DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Example

[0020] See also Figure 1-Figure 4The packaging material plate flattening device shown in the figure includes a shell 1, a telescopic cylinder 2 is provided on the top of the shell 1, one end of the telescopic cylinder 2 is fixedly connected to the pressing plate 3, a bearing plate 4 is provided below the pressing plate 3, the bearing plate 4 is slidably connected to the base 5, a spring 6 is provided inside the base 5, a plurality of fixed brackets 7 are provided on the outside of the base 5, the plurality of fixed brackets 7 are rotatably connected to a plurality of connecting plates 8, and one end of the plurality of connecting plates 8 is snap-fitted with a plurality of side pressing plates 9. The utility model is provided with a telescopic cylinder on the top of the shell, the telescopic cylinder is fixedly connected to the pressing plate, the bearing plate is provided below the pressing plate, the bearing plate is slidably connected to the base, a spring is provided inside the base, a fixed bracket is provided on the outside of the base to rotate the connecting plate, and the connecting plate is snap-fitted with the side pressing plate, so that the side pressing plate is driven when the bearing plate is pressed down, and additional pressure is applied to the side of the packaging material plate, thereby effectively solving the problem of bending or wavy unevenness of the side edge paper.

[0021] Furthermore, an extension plate 101 is provided on one side of the shell 1, and the extension plate 101 is fixedly connected to the telescopic cylinder 10. One end of the telescopic cylinder 10 is fixedly connected to the push plate 11, and the push plate 11 is slidably connected to the shell 1. By adding an extension plate on one side of the shell and the associated telescopic cylinder 10 and the push plate, the packaging material plate can be smoothly pushed out from the inside of the shell after the pressing is completed, thereby reducing manual intervention and reducing the difficulty of operation.

[0022] Furthermore, a connecting block 401 is provided at the bottom of the supporting plate 4, and a limiting rod 402 is provided inside the connecting block 401. The limiting rod 402 is slidably connected to the base 5. By setting a connecting block at the bottom of the supporting plate and equipping a limiting rod inside the connecting block, the shaking or misalignment that may occur during the flattening process is reduced, thereby ensuring the stability and accuracy of the flattening operation, and at the same time, disassembly and installation become more convenient and quick.

[0023] Furthermore, a positioning rod 501 is provided inside the base 5, and a spring 6 is provided outside the positioning rod 501. One end of the spring 6 is tightly pressed against the bottom of the connecting block 401. The positioning rod provided inside the base improves the accuracy and efficiency of the flattening operation. By providing elasticity and buffering functions, the service life of the equipment is extended, the maintenance cost is reduced, and the product quality and production efficiency are also improved.

[0024] Furthermore, a connecting rod 801 is provided at one end of the connecting plate 8, and a counterweight rod 802 is provided inside the connecting rod 801. The connecting rod 801 tightly presses the side pressure plate 9. The combination of the connecting plate, the connecting rod and the side pressure plate ensures that the side pressure plate can accurately and smoothly flatten the side of the packaging material plate under the drive of the connecting plate. The counterweight rod arranged inside it also provides stable counterweight support for the side pressure plate, effectively preventing the side pressure plate from shaking or deflecting during the flattening process, thereby ensuring the accuracy and consistency of the flattening.

[0025] Furthermore, a sliding rod 901 is provided at the bottom of the side pressure plate 9, and a limit block 902 is provided in the middle of the side pressure plate 9. The sliding rod 901 is slidably connected to the inside of the shell 1, and the limit block 902 tightly presses the connecting rod 801. The sliding rod added at the bottom of the side pressure plate and the limit block in the middle ensure the precise movement of the side pressure plate during the flattening process, and effectively reduce friction and resistance, thereby preventing the side pressure plate from being offset or excessively moved during the movement.

[0026] In this solution, the working process is: first, place the material plate on the carrying plate, then start the telescopic cylinder to push the pressure plate downward to flatten the packaging material plate on the carrying plate; at this time, the carrying plate moves downward with the cooperation of the spring and the base, and at the same time, the side pressure plate performs additional flattening operations on the side of the material plate under the action of the connecting plate and the connecting rod to ensure that the side will not bend or wave-like and uneven.

[0027] When the pressure plate and the side pressure plate complete their respective flattening actions, the telescopic cylinder and telescopic cylinder 2 are gradually retracted, so that the pressure plate and the load-bearing plate return to their initial positions. Then the telescopic cylinder 2 is started to push the push plate to slide along the outer shell and push the pressed packaging material plate to one side, waiting for the operator to take out the flattened packaging material plate.
