[0002] In the context of plastic product production, the development of automatic stamping and forming equipment is to meet the growing market demand, improve production efficiency and reduce production costs. However, traditional plastic bottle cap stamping and forming equipment has some shortcomings in some aspects, which limits its application in efficient and automated production.

[0003] Inefficient workflow: Some traditional stamping equipment may use manual or semi-automatic workflows, which require more manual intervention and operation. This leads to relatively low production efficiency, especially under high production demand, and cannot meet the requirements of fast production.

[0004] The export process is not automated enough: some equipment may require additional manual operation to push or export the formed bottle caps after stamping and shaping. This not only increases the production cycle, but also easily causes operational errors and reduces the overall automation level.

[0005] Risk of human error: Since there are many links that require human intervention, there is a risk of human error, which may lead to increased scrap rate and reduced product quality.

[0006] Therefore, this invention proposes a kind of automatic punching and forming device for plastic bottle caps to solve the above problems. Utility Model Content

[0045] Please refer to the instruction manual Figure 1-Figure 5 The utility model provides an automatic stamping and forming device for plastic bottle caps, comprising a bottom chassis 1, wherein a stamping feeding belt 2 and a discharge conveyor belt 10 are installed in parallel in the upper and lower order inside the bottom chassis 1, and a plurality of lower forming molds 3 are arranged equidistantly on the top of the stamping feeding belt 2 along the conveying direction of the belt surface thereof, and a top platform 7 is arranged directly above the bottom chassis 1, and a telescopic cylinder 8 is installed at the center of the top platform 7, and a lifting platform 9 is connected to the output end of the telescopic cylinder 8, and a plurality of stamping and shaping components 4 are installed at the bottom of the lifting platform 9;

[0046] A forming groove 31 is provided at the top center of the forming mold 3;

[0047] The stamping and shaping component 4 comprises:

[0048] A fixed block 41 installed at the bottom of the lifting platform 9;

[0049] A stamping column 42 disposed at the bottom center of the fixing block 41;

[0050] A bottle cap ejection ring 43 slidably sleeved on the punching column 42;

[0051] An annular connection pad 44 connected between the bottle cap ejection ring 43 and the fixing block 41;

[0052] A return spring 45 sleeved on the upper end of the punching column 42 and pressed tightly between the fixing block 41 and the bottle cap ejection ring 43;

[0053] Among them, the telescopic cylinder 8 drives the lifting platform 9 to move downward, thereby causing several stamping and shaping components 4 to stamp on the top of several lower forming molds 3 at this position of the stamping feeding belt 2. At this time, the stamping columns 42 in several stamping and shaping components 4 are correspondingly stamped to the inside of the molding grooves 31 inside the several lower forming molds 3 at this position, until the bottle cap ejection ring 43 is pressed and slid upward. At this time, the internal liquid plastic is pressed into a bottle cap shape, and then the telescopic cylinder 8 is started again to drive the lifting platform 9 to lift upward. At this time, the stamping column 42 is separated from the inside of the molding groove 31. At this time, the reset spring 45 rebounds and the bottle cap ejection ring 43 can be pushed downward to its original position. At this time, the bottle cap adhered to the stamping column 42 can be pushed down and remain in the inside of the molding groove 31, and then follow the stamping feeding belt 2 to return to the bottom, and finally fall off in the molding groove 31 and fall on the top belt surface of the unloading conveyor belt 10, and finally exported at one end.

[0054] An injection molding machine case 5 is installed at the front end of the top of the bottom case 1 , and an injection molding gun 6 is installed at the bottom center of the injection molding machine case 5 . The output end of the injection molding gun 6 is located directly above the movement trajectory of the plurality of lower molding molds 3 .

[0055] A transmission assembly 13 is provided at the front end of the outer wall of the bottom chassis 1;

[0056] The transmission assembly 13 comprises:

[0057] A first transmission sprocket 131 connected to the end of the front end driving roller inside the punching feeding belt 2;

[0058] A second transmission sprocket 132 connected to the end of the front end driving roller inside the discharge conveyor belt 10;

[0059] and a transmission chain 133 sleeved between the first transmission sprocket 131 and the second transmission sprocket 132;

[0060] The design of the first transmission sprocket 131 , the second transmission sprocket 132 and the transmission chain 133 can ensure that the stamping feeder belt 2 and the discharge conveyor belt 10 share the same power source.

[0061] A driving motor 12 is disposed at the rear end of the outer wall of the bottom chassis 1 , and the output end of the driving motor 12 is connected to the end of the rear end driving roller inside the stamping feed belt 2 .

[0062] Guide columns 91 are provided on both sides of the top of the lifting platform 9 , and the guide columns 91 on both sides are correspondingly slidably connected to the inside of the top platform 7 .

[0063] The annular connection pad 44 is made of a flexible and resilient material.

[0064] The top surface of the stamping support platen 11 is supported on the bottom of the top belt surface of the stamping feeding belt 2 .

[0065] Bottle cap stamping and shaping workflow:

[0066] Feeding and positioning: At the beginning, the stamping feeder belt 2 and the unloading conveyor belt 10 are in a standby state. The injection gun 6 in the injection molding machine box 5 injects the liquid plastic into the molding groove 31 in the lower molding mold 3. The stamping feeder belt 2 is driven by the transmission assembly 13 to transport the multiple lower molding molds 3 to be stamped to the bottom of the multiple stamping shaping assemblies 4.

[0067] Stamping process: the telescopic cylinder 8 is started to move the lifting platform 9 downward. The stamping column 42 of the stamping shaping component 4 punches into the molding groove 31 of the lower molding die 3 to press the liquid plastic into a bottle cap shape. The plastic stamping molding is completed until the bottle cap is ejected and the sleeve ring 43 is pressed and slides upward.

[0068] Lifting and pushing: The telescopic cylinder 8 is started again, and the lifting platform 9 is lifted upward, so that the punching column 42 is separated from the forming groove 31. The return spring 45 rebounds and pushes the bottle cap ejection ring 43 downward to the original position. At this time, the bottle cap adhered to the punching column 42 is pushed down and remains in the forming groove 31.

[0069] Discharging and returning: the punching feeder belt 2 runs again, and the bottle cap in the lower forming mold 3 is moved downward together with the forming groove 31. Finally, the bottle cap falls off inside the forming groove 31 and falls on the top belt surface of the discharging conveyor belt 10.

[0070] Finished product export: The unloading conveyor belt 10 smoothly exports the punched bottle caps through the power source at its driving end, completing the entire automatic punching and automatic collection operation.
