Description

Technical Field

[0001] The invention relates to the technical field of candy packaging and processing, and in particular to a claw plate module of a packaging machine. Background Art

[0002] As the main component of the packaging machine, the claw plate module performs indexed intermittent motion, which plays an important role in the periodic packaging of products.

[0003] In the existing claw plate module, although the chocolate is clamped and fixed by the joint movement of the cam, the current operation mode is that one side of the claw is a fixed side and the other side is a movable side. The ejector rod pushes the product to be packaged into the clamping range of the claw, and then moves from the movable side of the gripper to the fixed side, so as to achieve the purpose of fixing the product.

[0004] Since each product is not very regular, every time the feed rod pushes the product to the clamping position of the claw, some irregular products are easy to hit the claw. For example, some products have one side protruding more, and the product will interfere with the fixed edge of the claw when the push rod feeds the product. These products that hit the claw will be squeezed and damaged by the mechanical structure. Therefore, the compatibility effect of the current gripping method cannot meet expectations. Summary of the invention

[0005] The present invention aims to provide a claw plate module of a packaging machine, in which the claws do not interfere with the product when a push rod feeds the material, so that the overall operation of the packaging machine is more stable.
