[0002] With the rapid development of the modern packaging industry, PVC zipper bags are widely used in many fields such as food, medicine, cosmetics, daily necessities, etc. due to their good transparency, flexibility and certain barrier properties. For example, in food packaging, PVC zipper bags can facilitate consumers to open and reseal, and are used to package snacks such as nuts and candies. However, in the actual production process, the quality problems of the bag edges gradually emerge, so it is necessary to flat press the edges of PVC zipper bags.

[0003] However, in the process of using the existing bag edge flat pressing device, since the pressure directly acts on the PVC zipper bag, it will cause indentations, deformations or even breakages on the bag edge, and there will also be permanent indentations on the bag edge, affecting the appearance and normal use of the bag. Content of the Utility Model

By setting a buffer mechanism, it solves the problems that in the process of using the existing bag edge flat pressing device, since the pressure directly acts on the PVC zipper bag, it will cause indentations, deformations or even breakages on the bag edge, and there will also be permanent indentations on the bag edge, affecting the appearance and normal use of the bag.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model is a PVC zipper bag edge flat pressing device, which includes a workbench, and a buffer mechanism and a positioning mechanism are arranged on the workbench;

[0007] A U-shaped support plate is fixedly connected to the top of the workbench, a hydraulic cylinder is fixedly connected to the top of the U-shaped support plate, the output shaft of the hydraulic cylinder slides through the U-shaped support plate, a connecting plate is fixedly connected to the output shaft of the hydraulic cylinder, a flat pressing plate is arranged below the connecting plate, two sliding grooves are opened on the workbench, the buffer mechanism includes a buffer component and a buffer component two, the buffer component includes a plurality of telescopic rods fixedly connected to the top of the flat pressing plate, the tops of the plurality of telescopic rods are all fixedly connected to the connecting plate, a first spring is sleeved on the outer walls of the plurality of telescopic rods, the tops of the plurality of first springs are all fixedly connected to the connecting plate, and the bottoms of the plurality of first springs are all fixedly connected to the flat pressing plate.

[0008] Further, the buffer component two includes a trapezoidal sliding groove opened on the top of the flat pressing plate, and an L-shaped moving plate is slidably connected to the inner wall of the trapezoidal sliding groove.

[0009] Furthermore, two U-shaped support plates are fixedly connected to the top of the flat pressing plate, and the two L-shaped movable plates are fixedly connected to a sliding rod 1 on one side away from each other, and the two sliding rods 1 slide on the other side away from each other to observe the two U-shaped support plates and extend to the outside.

[0010] Furthermore, a spring 2 is sleeved on the outer wall of the two sliding rods 1, and the sides of the two springs 2 that are close to each other are fixedly connected to the two L-shaped movable plates respectively, and the sides of the two springs 2 that are away from each other are fixedly connected to the two U-shaped support plates respectively, and the tops of the two L-shaped movable plates are fixedly connected with an arc-shaped elastic plate, and the tops of the arc-shaped elastic plates are in contact with the connecting plate.

[0011] Furthermore, the positioning mechanism includes a positioning component 1 and a positioning component 2. The positioning component 1 includes a support plate fixedly connected to the inner wall of the workbench, and a motor is fixedly connected to the top of the support plate.

[0012] Furthermore, a rectangular block is fixedly connected to the bottom of the workbench, a rotating shaft is rotatably connected to the bottom of the rectangular block, and the output shaft of the motor is fixedly connected to the rotating shaft through a coupling.

[0013] Furthermore, the positioning assembly 2 includes a connecting rod 1 fixedly connected to the outer wall of the rotating shaft, and a connecting rod 2 is hingedly provided on the left and right sides of the connecting rod 1.

[0014] Furthermore, a second slide rod passes through the central axis of the rectangular block, and the second slide rod is fixedly connected to the rectangular block.

[0015] The utility model has the following beneficial effects:

[0016] 1. By setting a buffer mechanism, the hydraulic cylinder can be started after positioning is completed. The hydraulic cylinder drives the flat plate to move downward through the connecting plate. When the flat plate contacts the zipper bag, the flat plate will stop pressing down. Since the connecting plate is still pushed downward by the hydraulic cylinder, the telescopic rod and spring 1 cooperate with each other to provide preliminary buffering for this pressure. Due to the downward pressure of the connecting plate, the two L-shaped moving plates will move away from each other under the action of the arc-shaped elastic plate. As the two L-shaped moving plates move away from each other, the two springs 2 will also be compressed, thereby further buffering the pressure, so that it can avoid the problems of indentation, damage or deformation of the bag edge caused by the sudden excessive pressure exerted by the flat plate, thereby ensuring the integrity and normal use of the bag.

[0017] 2. By setting a positioning mechanism, when the PVC zipper bag needs to be flattened, the PVC zipper bag to be flattened can be placed on the workbench, and the motor is started to drive the rotating shaft to rotate one circle. When the rotating shaft rotates, the two sliders are driven to approach each other through the connecting rod 1 and the connecting rod 2 under the action of the sliding rod 2, thereby driving the two positioning plates to approach each other, and then positioning the zipper bag in the middle of the workbench, so as to ensure that in the subsequent bag edge flattening process, the pressure on each part of the bag edge is more uniform, so that each part of the bag edge can be properly flattened, thereby improving the flattening quality.

There is a second slide bar 323 running through it, which is fixedly connected to the rectangular block 313. Two sliders 324 are slidably connected to the outer wall of the rectangular block 313. The bottoms of the two sliders 324 are hinged to the two connecting rods 322 respectively. The tops of the two sliders 324 are fixedly connected with positioning plates 325.

[0030] A specific application of this embodiment is as follows: when in use, first place the device in the corresponding position, place the PVC zipper bag to be flattened on the workbench 1, start the motor 312, and drive the rotating shaft 314 to rotate one circle. When the rotating shaft 314 rotates, it will drive the two sliders 324 to move closer to each other under the action of the slider 323 through the connecting rod 1 321 and the connecting rod 2 322, thereby driving the two positioning plates 325 to move closer to each other, and then positioning the zipper bag in the middle of the workbench 1, so that it can ensure that in the subsequent bag edge flattening process, the pressure on each part of the bag edge is more uniform, so that each part of the bag edge can get appropriate flattening, improving the flattening quality. After the positioning is completed, the hydraulic cylinder 102 can be started. The hydraulic cylinder 102 The connecting plate 103 drives the flat pressing plate 104 to move downward. When the flat pressing plate 104 contacts the zipper bag, the flat pressing plate 104 stops pressing downward. Since the connecting plate 103 is still being pushed downward by the hydraulic cylinder 102, the telescopic rod 211 and the first spring 212 cooperate with each other to initially buffer the pressure. Due to the downward pressure of the connecting plate 103, the two L-shaped movable plates 222 are moved away from each other under the action of the arc-shaped elastic plate 226. As the two L-shaped movable plates 222 move away from each other, the two second springs 225 are also compressed, thereby further buffering the pressure. This can prevent the flat pressing plate from suddenly applying excessive pressure, which may cause indentations, damage or deformation on the bag edge, thereby ensuring the integrity and normal use of the bag.
