Description

Technical Field

[0001] The utility model belongs to the technical field of co-injection cap production and processing, and particularly relates to an internal and external integrated wrapping machine for co-injection cap production and processing. Background Art

[0002] A co-injection cap is a bottle cap manufactured by using co-injection molding technology. It combines two or more plastic materials and forms an integrated product in the same mold through multi-layer injection molding technology. It has different plastic materials for the inner layer and the outer layer to enhance sealing performance or chemical resistance, etc. It is commonly used in the fields of food, beverages, pharmaceuticals, etc., and can provide better performance than single materials while maintaining production efficiency and cost-effectiveness.

It can not only cooperate with the injection process to inject the outer layer and inner layer raw materials, but also push down a plurality of co-injection lids fixed on the injection machine housing 21 due to hardened raw materials in the spray nozzle 210 through the sliding rod 211, completing the function of automatically removing the co-injection lids, without manual operation to remove them, effectively avoiding the occurrence of personnel accidents to a certain extent.

[0031] As shown in Figure 2 and Figure 3 The moving mechanism 3 includes a driving component, a linkage component and a sliding component. The driving component includes a motor 31 fixedly connected to the top surface of the receiving plate 1. A fixed ring 32 is fixedly connected to the top surface of the receiving plate 1. The output end of the motor 31 is fixedly connected to a rotating shaft 33. The left end of the rotating shaft 33 is rotatably connected to the right side of the fixed ring 32. The linkage component includes two belt grooves 34 formed on the outer wall of the rotating shaft 33. Two belt pulleys 35 are rotatably connected to the right side of the fixed ring 32.

The left ends of the two threaded rods 38 extend to the inner wall of the second sliding groove 37 and are rotatably connected to the second sliding groove 37. Sliders 39 are slidably connected to the inner walls of the two second sliding grooves 37. The inner walls of the two sliders 39 are threadedly connected to the outer wall of the threaded rod 38.

[0032] By setting the moving mechanism 3, the motor 31 is used to drive the two sliders 39 to drive the mold pressing block 43 to slide, assisting the injection molding mechanism 2 to bring a plurality of mold grooves 44 on the mold pressing block 43 into contact with a plurality of material spraying nozzles 210, and cooperating to complete the injection molding process, further realizing automated operation.

[0033] As shown in Figure 2 and Figure 3 The mold mechanism 4 includes a support component and a mold component. The support component includes a plurality of support columns 41 fixedly connected to the bottom surface of the receiving plate 1. A sealing ring 42 is fixedly connected to the right side of the injection molding machine housing 21. The mold component includes a mold pressing block 43 fixedly connected to the side where the two sliders 39 are close to each other. A plurality of mold grooves 44 are formed on the left side of the mold pressing block 43.

[0034] By setting the mold mechanism 4, the plurality of support columns 41 play a role in supporting the device, the sealing ring 42 plays a role in sealing the injection molding when the mold grooves 44 on the mold pressing block 43 are connected to the material spraying nozzles 210, and the shapes of the mold grooves 44 on the mold pressing block 43 correspond to the outer shape of the co-injection lid to be produced.

[0035] A specific application of this embodiment is as follows: By setting up the injection molding mechanism 2, when the outer layer raw material enters from the first feed pipe 213 and the inner layer raw material enters from the second connecting pipe 215, the hydraulic cylinder 23 in the fixed cylinder 22 drives the push plate 25 to slide in the first chute 24. The push plate 25 pushes the sliding rod 211 in the injection pipe 27 to slide in the nozzle 210, adjusting the sliding position of the sliding rod 211. According to the injection molding process, the hydraulic cylinder 23 drives the sliding rod 211 to slide backward, blocking the connection port of the inner plastic groove 29, connecting the space between the nozzle 210 and the inner wall of the outer plastic groove 28. The outer layer raw material enters the outer plastic connecting pipe 212 through the first feed pipe 213, injects a certain amount of the outer layer raw material, and then enters the nozzle 210 through the outer plastic groove 28. Cooperating with the moving mechanism 3, the mold pressing block 43 is driven to be fixed on the right side of the injection molding machine housing 21. The outer layer raw material is injected into the mold groove 44 through the nozzle 210. When it reaches a certain amount, the sliding rod 211 retracts again to expose the connection port of the inner plastic groove 29. Then the inner layer raw material enters the inner plastic connecting pipe 214 through the second connecting pipe 215, flows into the inner plastic groove 29 from the inner plastic connecting pipe 214, and enters the nozzle 210 from the exposed connection port of the inner plastic groove 29, and is injected into the mold groove 44 together with the outer layer raw material. After injection molding, through a certain period of cooling, the co-injection lid formed by injection molding hardens and is fixed. And there is still a certain amount of relatively hardened raw material left at one end of the co-injection lid in the nozzle 210. The hydraulic cylinder 23 drives the sliding rod 211 to push forward to eject the hardened raw material remaining in the nozzle 210 from the nozzle 210. The co-injection lid falls and is collected by the subsequent process, completing the detachment of the co-injection lid. It realizes the sliding adjustment of the sliding rod 211 driven by the hydraulic cylinder 23 in the injection pipe 27 and the nozzle 210. It can not only cooperate with the injection molding process to inject the outer layer and inner layer raw materials, but also use the sliding rod 211 to push down several co-injection lids fixed on the injection molding machine housing 21 due to the hardened raw material in the nozzle 210, completing the function of automatically removing the co-injection lid, without the need for manual operation to remove it, effectively avoiding the occurrence of personnel accidents to a certain extent.

[0036] By setting up the moving mechanism 3, the motor 31 drives the rotating shaft 33 to rotate. Under the mutual cooperation of the belt groove 34, the belt 36 and the belt pulley 35, the rotating shaft 33 drives the two belt pulleys 35 to rotate synchronously through the linkage of the belt 36 on the two belt grooves 34. The rotation of the two belt pulleys 35 drives the two threaded rods 38 to rotate. Since the two sliders 39 are threadedly connected to the two threaded rods 38, the rotation of the two threaded rods 38 drives the two sliders 39 to slide synchronously along the thread in the two second chutes 37 respectively, driving the mold pressing block 43 fixed on the two sliders 39 to slide into the sealing ring 42. It realizes the sliding of the two sliders 39 driven by the motor 31 to drive the mold pressing block 43, assisting the injection molding mechanism 2 to bring the several mold grooves 44 on the mold pressing block 43 into contact with the several nozzles 210, and cooperating to complete the injection molding process, further realizing automated operation.

[0037] By setting the mold mechanism 4, several support columns 41 play a supporting role for the device, and the sealing ring 42 plays a sealing role for injection molding when the mold groove 44 on the mold pressing block 43 is connected to the material spraying nozzle 210. The shape of the mold groove 44 on the mold pressing block 43 corresponds to the outer shape of the co-injection lid to be produced.
