[0002] Polyethylene foamed cotton is a non-crosslinked closed-cell structure, also known as EPE pearl cotton, which is a new type of environmentally friendly packaging material. It is composed of countless independent bubbles generated by physical foaming of low-density polyethylene resin. It overcomes the disadvantages of ordinary foamed glue such as being fragile, deformed, and having poor recoverability. It has many advantages such as water resistance, moisture resistance, shock resistance, sound insulation, heat preservation, good plasticity, strong toughness, recyclability, environmental protection, and strong impact resistance. It also has good chemical resistance and is an ideal substitute for traditional packaging materials. A punching device for EPE processing is disclosed in the prior art, with the application number: CN202220934585.4, including a support block. One side of the support block is welded with an L-shaped block, the bottom of the L-shaped block is welded with a round tube, the side of the round tube away from the L-shaped block is fixedly communicated with a first rectangular hole block, the inner wall top of the first rectangular hole block is welded with two first guide plates, the side of the support block close to the L-shaped block is welded with a second rectangular hole block, the inner wall bottom of the second rectangular hole block is installed with a servo motor through a fixed block, and the rear surface of the inner wall of the first rectangular hole block is rotatably connected with two connecting rods through a first fixed bearing. In the above technical solution, the hydraulic rod drives the punching needle to punch the EPE. Therefore, during the punching process, only a single punching can be performed on the EPE. However, the usage scenarios of EPE are numerous, and the punching requirements are also different, resulting in a low punching range and unable to meet the production requirements. Therefore, the inventor proposes a punching device for EPE packaging products. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present utility model.

[0023] This specific embodiment is a punching device for EPE packaging products, and its structural schematic diagram is as Figure 1As shown in the figure, it includes a support box 1, a fixed plate 6, a template 7 and a driving box 2. The inner side of the support box 1 is a hollow structure, and a support plate 8 is installed above the inner side. One side of the support box 1 is fixedly installed with a support frame 3. The support frame 3 is in an L-shaped structure and extends upward toward the support box 1. A telescopic cylinder 5 is fixedly installed on the surface of the support frame 3 facing the support box 1. The telescopic cylinder 5 is arranged vertically, and the end away from the support frame 3 is connected to the fixed plate 6. The fixed plate 6 is in a C-shaped structure, and a template 7 is slidably installed inside. The template 7 corresponds to the support plate 8.

[0024] Referring to Figure 2 , a driving box 2 is installed on the upper surface of the fixed plate 6. Connecting pipes 14 are installed at both ends of the driving box 2 respectively. The connecting pipes 14 are in an L-shaped structure, with one end slidably connected to the driving box 2 and the other end extending out. A limiting rod 15 is fixedly connected to the end of the connecting pipe 14 extending out of the driving box 2. The limiting rod 15 passes through the side wall of the fixed plate 6 and is inserted into the template 7. There are limiting holes 9 on the side wall of the template 7, and the limiting rod 15 is inserted into the limiting holes 9 in a matching manner. An adjusting knob 4 is rotatably installed above the driving box 2. A rotating shaft 10 is horizontally installed inside the driving box 2. There are meshing bevel gears one and two between the rotating shaft 10 and the adjusting knob 4. Driving screws 12 are installed at both ends of the rotating shaft 10 respectively. The driving screws 12 are threadedly connected to the connecting pipes 14.

[0025] Referring to Figure 3 , Figure 4 , there are support strips 17 on the inner wall of the support box 1. The support plate 8 is in contact with the support strips 17. A limiting groove 16 is opened on the side wall of the support plate 8. An adjusting screw 18 is threadedly installed on the outer wall of the support box 1. The adjusting screw 18 threadedly penetrates into the support box 1 and is rotatably connected to a limiting block 19. The limiting block 19 is inserted into the limiting groove 16 in a matching manner.

[0026] Working principle: When in use, first replace the support plate 8 and the template 7 according to the punching requirements of the EPE. By rotating the adjusting screw 18 to drive the limit block 19 away from the limit groove 16, the support plate 8 can be removed from the inside of the support box 1. After replacing the support plate 8 with a suitable specification, rotate the adjusting screw 18 again to insert the limit block 19 and the limit groove 16 into each other, and the support plate 8 can be fixed. The replacement method of the template 7 is to rotate the adjusting knob 4. The adjusting knob 4 drives the rotating shaft 10 to rotate, and then drives the screw 12 to rotate under force. The connecting pipe 14 threadedly connected to the driving screw 12 slides out along the driving box 2, and then the limit rod 15 at the bottom moves synchronously and moves out from the inside of the limit hole 9, so that the template 7 can be taken out from the inside of the fixing plate 6. After replacing the template 7 with a suitable specification, rotate the adjusting knob 4 in the reverse direction to drive the connecting pipe 14 to retract into the inside of the fixing plate 6, and the limit rod 15 slides along the fixing plate 6 until it is inserted into the limit hole 9, and the template 7 can be limited with the fixing plate 6. The template 7 is provided with protruding needles, and the support plate 8 is provided with concave holes. The needles and the concave holes cooperate to punch the EPE.

[0027] Subsequently, start the telescopic cylinder 5. The telescopic cylinder 5 extends to drive the fixing plate 6 to lower the height, and then the template 7 can be forced to move towards the support plate 8. Place the EPE raw material on the upper surface of the support plate 8. When the template 7 approaches the support plate 8, the EPE is punched. The replaceable support plate 8 and template 7 can be adapted to different punching requirements. The EPE waste generated by punching enters the support box 1 for collection. A door panel is hinged on the support box 1 (which can be set at any position of the support box 1). After opening the door panel, the EPE waste can be cleaned up uniformly.

[0028] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
