Embodiment

[0045] Example: a production equipment for a vest bag with a back, see figure 1, including the frame, the feeding device 1 arranged on the frame, the tensioning device 2 arranged on one side of the feeding device 1, the connecting device 3 arranged on the frame, and the connecting device 3 is arranged away from the feeding device 1-1 The adjustment device 4 on the side, the heat sealing device 5 arranged on the side of the adjustment device 4 away from the feeding device 1, the adjustment component 6 arranged on the side of the heat sealing device 5 away from the feeding device 1, the adjustment component 6 arranged on the side away from the feeding device 1 The die-cutting device 7 on one side, the scrapping device 8 arranged on the side of the die-cutting device 7 away from the feeding device 1 , and the discharging device 9 arranged on the side of the scrapping device 8 away from the feeding device 1 .

[0046] There are two sets of tensioning devices 2 and adjusting device...

Embodiment 2

[0074] Embodiment 2: a kind of production process of even-back vest bag, comprising the following steps:

[0075] Step 1: Loading. Place the double-layer plastic film roll folded inward on both sides on the feeding device 1, and connect the head end of the new plastic film roll with the tail end of the old plastic film roll through the connecting device 3 to maintain the plastic film. Continuity of feed.

[0076] Step 2: Tension and temporary storage. During the processing of the plastic film, the plastic film is tensioned by the tensioning device 2 to reduce wrinkles and stacking of the plastic bag. And the plastic film is temporarily stored to balance the uneven feeding problem caused by the fast and slow operation of the equipment.

[0077] Step 3: Adjust. Due to the existence of tension, the trajectory of the movement of the plastic film is greatly increased, and a small change will cause the position of the feed to be offset. stability.

[0078] Step 4: Heat sealing...

Abstract

The present application discloses a production equipment and a process for an even-back vest bag, which relates to the technical field of bag making. The discharging device arranged at the discharging end of the frame also includes a die-cutting device arranged between the heat-sealing device and the discharging device; the die-cutting device includes a die-cutting bracket, a workbench arranged at the top of the die-cutting bracket, and a die-cutting device fixed on the die-cutting bracket. A support frame at the top of the workbench, a die-cutting block connected to the support frame, a die-cutting roller rotatably connected with the die-cutting block, and a die-cutting die set on the die-cutting roller. The present application has the effect of optimizing the production process and reducing the occurrence of irregular cutting of the bag body.

Description

technical field [0001] The present application relates to the technical field of bag making, in particular to a production equipment and a process for a vest bag with a back. Background technique [0002] Vest bag, also known as vest bag, is a kind of common plastic bag. It is named after its shape resembles a vest. Most vest bags include two bag bodies with the same structure. The upper edge of the bag body has an upwardly extending handle. The lower edges of the bag body are pressed together, and the two edges on the left and right sides have inwardly folded expansion parts and are connected together. In the production process, the bag body of the vest bag is formed by heat-sealing the double-layer plastic film folded inward on both sides, and the handle of the vest bag is formed by cutting the bag body. Stacking is performed, and then the stacked bag bodies are cut to form the handles of the vest bag. However, stacking first and then cutting will cause uneven stacking, ...
