Embodiment

[0045] Embodiment: a kind of waistcoat bag production equipment, see figure 1, including a frame, a feeding device 1 arranged on the frame, a tensioning device 2 arranged on one side of the feeding device 1, a connecting device 3 arranged on the frame, and a connection device 3 arranged on a side far away from the feeding device 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 assembly 6 arranged on the side of the heat sealing device 5 away from the feeding device 1, the adjustment assembly 6 arranged on the side away from the feeding device 1 The die cutting device 7 on one side, the waste removal device 8 arranged on the side away from the feeding device 1 of the die cutting device 7 , and the discharge device 9 arranged on the side of the waste removal device 8 away from the feeding device 1 .

[0046] There are two groups of tensioning devices 2 and adjusting de...

Embodiment 2

[0074] Embodiment two: a kind of production process of even back waistcoat bag, comprises 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 temporarily store the plastic film to balance the problem of uneven feeding caused by the fast and slow operation of the equipment.

[0077] Step three: adjust. Due to the existence of tension, the trajectory of the plastic film movement is greatly increased, and small changes will cause the position of the feed to be shifted. By adjusting the adjustment device 4, the...

Abstract

The invention discloses vest bag production equipment and a vest bag production technology, and relates to the technical field of bag making. According to the technical scheme, the vest bag productionequipment is characterized by comprising a rack, a loading device arranged on the rack, a heat seal device arranged at one side of the loading device, and a discharging device arranged at a discharging end of the rack, and further comprising a die cutting device arranged between the heat seal device and the discharging device; and the die cutting device comprises a die cutting support, a workbench arranged at the top end of the die cutting support, supporting frames fixed to the top end of the workbench, die cutting blocks connected with the supporting frames, die cutting rollers rotatably connected with the die cutting blocks, and die cutting molds arranged on the die cutting rollers. The vest bag production equipment and the vest bag production technology have the effects that a production technology is optimized, and the situations of uneven trimming of bag bodies are reduced.

Description

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