Description

Technical Field

[0001] The utility model belongs to the technical field of liquid packaging bottle cap processing, in particular to a shearing structure for injection molding waste of liquid packaging bottle plastic bottle caps. Background Art

[0002] A bottle cap is a device used to close or seal a container, such as a bottle, jug, can, tube, or jar. It can take many forms, including caps (in the narrow sense of the word), lids, and stoppers. The main types of caps include twist-on caps, crown caps, flip-top caps, and corks. Plastic packaging bottle caps are injection molded and then trimmed around the cap using a shearing mechanism to create a smooth surface before use.

[0003] Among them, the utility model patent with publication (announcement) number CN220373766U discloses a shearing structure for plastic bottle cap injection molding waste, including a shearing mechanism, a pressing member provided on one side of the shearing mechanism, the upper end of the pressing member being connected to a movable structure, and the bottom wall of the movable structure being mounted on the surface of a processing table, the upper end of the processing table being further provided with a placement structure for placing the injection molded bottle cap products, and the lower end of the processing table being fixedly mounted with support legs for support; the surface of the processing table being fixedly mounted with raised blocks, the placement structure comprising a placement plate provided at the upper end of the processing table and mounting blocks provided at the front and rear sides of the placement plate, the position of the mounting blocks being fixed by bolts, the surface of the placement plate being uniformly provided with circular grooves, and the surface of the processing table also being provided with open grooves, the open grooves and the circular grooves being connected. When the operator uses the provided electric push rod structure to start in the positive direction, the shearing blade can be moved downward until the periphery of the bottle cap is sheared, making the periphery of the bottle cap smooth.

[0004] However, in actual use, it was found that after the shearing blade sheared around the bottle cap, the bottle cap would be stuck in the inner cavity of the circular groove. Since the bottle cap was upside down on the surface of the raised block, it was inconvenient for the user to pick out the bottle cap. Therefore, it is necessary to design a shearing structure for injection molding waste of liquid bottle plastic bottle caps to solve the above problem. Utility Model Content
