Description

Technical Field

[0001] The utility model relates to the technical field of candy packaging and processing, and particularly relates to a sugar paper pre-pressing mechanism of a packaging machine. Background Art

[0002] Nowadays in the market, there are various candies and endless packaging methods. Among them, the kink-packaged candies are quite popular. Therefore, there are corresponding single-twist or double-twist paper wrapping machines for candies to perform kink packaging on small candies. The full-automatic packaging of the paper wrapping machine can also reduce contact with humans, avoid secondary pollution, increase packaging efficiency and product qualification rate, and greatly reduce production costs compared with manual packaging.

[0003] The current packaging method is as follows: After the candies are fed and transported in place, the paper feeder senses the paper feeding and sends the sugar paper above the sugar block. The top block and the upper punch respectively clamp the sugar block and the paper under the action of different cam-link mechanisms, and at the same time transport them upward. The sugar block is grasped by the sugar clamping hand, and then the swing arm installed on the mounting plate moves under the chocolate clamped by the sugar clamping hand at the first station, and folds the right sugar paper upwards to be close to the chocolate. Rotate to the second station. During the rotation process, passing through the arc plate, there is a small gap between the arc plate and the moving sugar block, so that the left sugar paper can be tightened and overlapped on the sugar paper tightly attached to the bottom right. Then directly, the tightening gripper at the second station grasps both ends of the sugar paper and tightens them. Since there is glue on both inner sides of the sugar paper, directly copying the paper by the paper copying block will cause the glue of one side of the sugar paper to stick to the bottom of the sugar or the sugar clamping hand, thus affecting the packaging quality.
