[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] The utility model provides a technical solution: Figure 1 - Figure 4 As shown, in this embodiment, a plastic bottle cap compression molding machine includes a protective cover 1, a compression molding frame 10 is arranged inside the protective cover 1, a plurality of driving devices 11 are fixedly installed on one side of the compression molding frame 10, a mounting groove 18 is provided inside the output end of the driving device 11, an elastic clamping ring 20 is fixedly installed inside the mounting groove 18, a threaded groove 17 is provided inside the driving device 11, a threaded ring 19 is threadedly connected to the inner wall of the threaded groove 17, a rotating ring 14 is fixedly connected to one end of the threaded ring 19, a concave mold 13 is clamped inside the elastic clamping ring 20, the inner wall of the threaded ring 19 is slidably connected to one side of the outer wall of the elastic clamping ring 20, and the rotating ring 14 is fixedly connected to the inner wall of the threaded ring 19. The rotating ring 14 causes the threaded ring 19 to rotate in the thread groove 17. When the threaded ring 19 is taken out of the driving device 11, the threaded ring 19 is separated from the elastic clamping ring 20, and the clamping block restriction on the elastic clamping ring 20 is released. The elastic force of the elastic clamping ring 20 itself will separate each clamping block, so that the concave mold 13 can be removed from the driving device 11. The structural design of the elastic clamping ring 20 and the threaded ring 19 is that the concave mold 13 can be disassembled and replaced by simply rotating the rotating ring 14 from the driving device 11, which reduces the replacement time and improves the production efficiency of plastic bottle caps. The male mold 12 is installed in the same manner as the female mold 13.

[0022] like Figure 2 As shown, a driving motor 7 is fixedly installed on one side of the inner bottom of the protective cover 1, and the output end of the driving motor 7 is transmission-connected with a bevel gear 15, and the outer wall of the bevel gear 15 is meshed with a gear plate 9, and the middle part of the upper end of the gear plate 9 is fixedly connected to the lower end of the compression molding frame 10, and a feeding device 6 is fixedly installed on one side of the inner wall of the protective cover 1. The cooperation of the driving motor 7 and the feeding device 6 can inject production raw materials into each concave mold 13 on the compression molding frame 10.

[0023] like Figure 2As shown, a limit ring 8 is fixedly connected to the other side of the inner bottom of the protective cover 1, and the inner wall of the limit ring 8 is slidably connected to the outer wall of the gear plate 9. The limit ring 8 is used to limit the rotation of the gear plate 9 to prevent the gear plate 9 from deflecting due to long-term rotation.

[0024] like Figure 1 and Figure 2 As shown, a feeding device 4 is provided on the other side of the inner wall of the protective cover 1 , and a plurality of male molds 12 are fixedly mounted on the other side of the compression molding frame 10 . The feeding device 4 is used to transport the bottle caps produced on the male molds 12 out of the protective cover 1 .

[0025] like Figure 1 and Figure 2 As shown, support feet 5 are fixedly connected to the four corners of the lower end of the protective cover 1, and a maintenance door 2 is rotatably connected to the other side of the protective cover 1. A transparent glass 3 is fixedly installed on one side of the maintenance door 2. The transparent glass 3 is used for the staff to observe the bottle cap compression molding.

A plurality of air inlet holes 22 are penetrated through the outer wall of the ventilation frame 21, and a heat dissipation semiconductor 23 is fixedly installed on one side of the inner wall of the ventilation frame 21. When the heat dissipation semiconductor 23 is turned on, the gas temperature in the ventilation frame 21 is reduced, and when the cooling fan 16 is turned on, the cooled gas is blown into the protective cover 1, thereby accelerating the cooling of the bottle caps on the male mold 12 and reducing the number of defective bottle caps when unloading.

The filter frame 24 is used to filter the gas sucked into the ventilation frame 21 to increase the service life of the cooling fan 16 .

[0028] The utility model provides a plastic bottle cap compression molding machine, the specific working principle is as follows:

[0029] When producing plastic bottle caps, firstly, the raw material is added into the concave mold 13 through the feeding device 6, and then the driving motor 7 is turned on to rotate the compression molding frame 10. The feeding device 6 adds the raw material to each concave mold 13. When the concave mold 13 moves out from the bottom of the feeding device 6, the driving device 11 will push the concave mold 13 onto the convex mold 12, so as to compression mold the bottle cap. Then, the cooling fan 16 and the cooling semiconductor 23 are turned on to cool the bottle cap on the convex mold 12, and then the unloading device is used to heat the bottle cap. The bottle caps on the male mold 12 are transported out. When it is necessary to produce bottle caps of different types, the rotating ring 14 is rotated to make the threaded ring 19 rotate in the threaded groove 17. When the threaded ring 19 is taken out from the driving device 11, the threaded ring 19 is separated from the elastic clamping ring 20, and the clamping block restriction on the elastic clamping ring 20 is released. The elastic force of the elastic clamping ring 20 itself will separate each clamping block, so that the female mold 13 can be removed from the driving device 11, and then the bottle cap mold to be produced can be replaced.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
