Description

Technical Field

[0001] This utility model relates to the technical field of bottle preform processing equipment, and in particular to a bottle preform servo tail shearing machine. Background Technology

[0002] One of the processes from the production of plastic preforms to their packaging is to cut off the residual plastic head, also known as tail trimming (when the plastic preform just comes out of the mold, the plastic inside the gating gate, which is connected to the mold cavity, comes out together with the preform body. The plastic inside the gating gate is attached to the top of the preform body, and the plastic inside the gating gate forms the residual plastic head, which is waste generated during production). In the above process, only the plastic head of one plastic preform can be cut off at a time, which is extremely inefficient. Moreover, the cutting position is different each time, which affects the quality of the plastic preform and has a significant impact on the subsequent processing of the plastic preform.

[0003] Traditionally, bottle trimming is mainly done manually, which is not only labor-intensive but also inefficient. To improve efficiency, some bottle trimming devices have emerged. However, existing trimming devices mainly use a conveyor belt to transport the preform to the lower end of the device, where the tail is cut off. This type of device not only requires a conveyor belt, increasing its footprint, but it can also typically only trim one or two preforms simultaneously, resulting in relatively low efficiency.
