0 bow rumors In China's beverage industry, PET bottle filling, plastic bottle cap sealed beverages have dominated, in order to prevent counterfeit and shoddy products, to ensure that the quality of the contents is not maliciously damaged, the current bottle caps are generally The anti-theft structure is adopted, and the cap is called an anti-theft cover. The anti-theft cover is composed of two parts, namely a cap body and an anti-theft ring, and the cap body and the anti-theft ring are connected by a connecting bridge. Once the cap is broken, the anti-theft ring remains on the bottle mouth. The traditional capping process is one-shot injection molding, which uses a slider-type core pulling mechanism to generate an anti-theft ring. The disadvantage of this molding process is that the mold structure is large, and the core pulling mechanism is easy to wear. With the wear of the core pulling mechanism, the cap body and the anti-theft ring are likely to be stuck. When the cap that produces the adhesion is opened, the cap body and the anti-theft ring are not easily separated, and the anti-theft ring is taken away from the bottle mouth by the cap body, which seriously affects the normal use of the cap. In order to solve the problem of the adhesion of the cap body and the anti-theft ring and the huge mold structure, this study uses a mechanical cutting method to generate an anti-theft ring to replace the one-shot injection molding process. 1 cap structure The beverage bottle cap mainly consists of two parts, namely the cap body and the anti-theft ring, and the cap body and the anti-theft ring are connected together through a connecting bridge. The main body of the bottle cap has a sealing inner plug, a thread, a capping tooth line, a connecting bridge and the like, and the anti-theft ring has a buckle. A typical beverage bottle cap is as shown. Anti-theft ring 2 cutting machine structure and working principle 2.1 Structure of the cutting machine The structural drawing of the vertical cutting machine is as shown. The cutting machine consists of four components: the power component, the head component, the gland wheel component, and the tool holder component. Parts such as gears (33) form a power component. The motor and the shaft are fixed on the frame (1), and the handle (34) and one of the bevel gears are fixed on the shaft, and the timing pulley and one of the bevel gears are fixed on the motor. The power component is used to power the entire machine. The handle and bevel gear are manual devices for use during commissioning and do not participate in normal cutting work. Head parts: machine table (2), spindle seat (3), spindle (4), head (28), ring gear holder (7), mechanical seal ring (10), ring (9), etc. The parts make up the head parts. The head unit is fixed to the frame (1) by the machine table. The spindle seat is fixed on the machine board, the spindle is fixed in the spindle seat, the ring gear fixing frame and the machine head are mounted on the spindle. The function of the head member is to drive the gland wheel member mounted inside it to rotate around the main shaft. A plurality of capping wheel members are evenly distributed on the circumference of the handpiece. The mechanical seal moving ring and the fixed ring are respectively connected with the machine head and the ring gear fixing frame, and are used for blowing air when the bottle cap is removed. Capping wheel parts: bearing housing (14), gland wheel (17), gland axle (14), gear (12) and the like constitute a gland wheel component. The bearing housing is mounted in the head (28), the gland axle is mounted in the bearing housing, and the gland wheel and gear are fixed to the gland axle. The function of the capping wheel member is to carry the planetary motion of the cap rotating and rotating around the main shaft, and press the cap to cut the cutter. The tool holder component: the tool holder (26), the cutter pressure plate (25), and the bottle side guide plate (23) and the like constitute a tool holder component. The knife seat is fixed on the main shaft (3), and the bottle side guide plate and the cutter pressing plate are fixed on the knife seat. The working principle of the cutter fixed on the cutting 2.2 cutting machine can be seen from the structure diagram of the cutting machine (as shown). The power is from the motor, and the moped head rotates around the main shaft through the timing belt. The gland wheel parts installed in the machine head are randomly. The head rotates together. The cutting schematic is shown. The cap is from the inlet air duct, and the cap surface of the cutting machine is all facing down. When the cap enters the cutting machine, it is placed on the gland wheel. The capping wheel is driven by the head and the gear to make the planetary motion of rotating and rotating around the main shaft, so that the cap is rolled on the cutting edge of the cutter. . During the cutting process, the cover surface of the bottle cap is supported by the bottom cover of the bottle cap (20), the upper surface is pressed by the gland ring (18) for axial positioning, and the outer side surface is closely attached to the cap side guide plate (23). The side is pressed by the capping wheel (17) to achieve radial positioning. The cutter is fan-shaped and has a sloped notch on the cutting edge. Since the cutter (20) is higher than the side guide of the bottle cap, the side wall of the cap is forcibly pierced by the cutter under the action of the pressure roller, and the gap of the cutter blade leaves a small section of the connecting bridge on the cap. The entire cap is cut into a tamper-evident cover composed of a cap body and an anti-theft ring. After the cutting process is completed, the compressed air from the air pipe joint (5) blows the bottle cap away from the gland wheel, and enters the cover air duct. The bottle cap enters the packing box through the cover air duct and the binning machine. 3 cutting cap process The whole process of cutting the cap is as shown. The operator manually adds the cap to the hoist, and the hoist automatically adds the cap to the capping machine. The capping machine arranges the caps into a traveling candidate cover plate, and the cover plate sends the caps facing downwards to the caps, and the caps facing upwards are sent back to the capping machine to re-queue. The cover air duct sends the cap facing down to the cutting machine for cutting, and the cut bottle cap enters the binning machine through the cover air duct. There are 2 capping stations at the exit of the binning machine. The binning machine will send the caps to one of the capping stations according to the required quantity. After the station reaches a certain number, the bottle will be sent to another one. Cover the work station to achieve the same number of caps per case. 4 The motor of the automatic control cutting machine and the cover machine is controlled by frequency conversion to meet the requirements of different production speeds. The hoist uses ordinary three-phase AC motor. The cutting machine usually uses two speeds, ie high speed cutting (1 200 / min) and normal cutting (1000 / min). If there is special speed requirement, it can be realized by manual frequency modulation. The cover machine usually has only one speed. If you need to change the speed, you can also use manual frequency modulation. The control diagram for the entire process flow is shown. The sensor 1 is mounted on the capping machine to control the number of caps in the capping machine. When the cap reaches a certain amount, the hoist stops working. The sensor 2 is installed on the air supply duct of the cover, and is a reverse cover detecting device. If the cover plate is operated incorrectly and the cover is fed into the cover air duct, the cutting machine stops working. The sensor 3 is installed on the air supply duct. If there is no bottle cover to enter the cutting machine, the cutting machine automatically turns to a low speed operation and is in a standby state. The cylinder 1 is installed in the population of the cutting machine, and the channel is automatically closed when the cutting machine is stopped, and the cap cannot enter the cutting machine. The sensor 4 is worn in the cutting machine. If the cover is jammed inside the machine, the cover will automatically stop. The sensor 5 is installed on the air outlet of the cover, and if the cover air duct is blocked, the cutting machine automatically stops. The counter is installed on the outlet air duct to control the number of caps of the cover station. When the cap of the cover station reaches a certain amount, the cylinder 2 automatically turns, and the cap is guided to another cover station to realize each bottle. The number of covers is equal. The sensor 6 is mounted on the shaft, and when the handle (34) is manually rotated, the cutter cannot be started to ensure the safety of the operator. 5 Conclusion This study uses mechanical cutting to create an anti-theft ring, avoiding the adhesion of the cap and improving the quality of the cap. The cutting machine is highly productive, with a cutting machine with 9 gland wheel parts producing 60,000 pieces per hour. Because it is a vertical structure, the bottle cap is easy to get out of the pressure roller, and it is not easy to block and cover the cap. After the anti-theft ring is mechanically cut, the cover mold does not need to be core-pulled, which simplifies the structure of the mold. The practice results show that the capacity of the injection cap is more than doubled. Take the 3025 anti-theft cap as an example. The distance between the two cavities of the mold without core is 67mm, and the distance between the two cavities of the core-pulling mold is 157mm. At the same time, it also avoids the disadvantages such as easy wear and trouble of the mold core pulling mechanism, reducing the maintenance cost and improving the life of the mold. The research results show that the design has obvious economic benefits and has a good promotion prospect.
