[0002] Polyurethane sponge is a low-density PU with a foam density below 18kg / m³. It is a porous elastic material made of polyurethane foam. Due to its good elasticity, it is often used in the packaging field to fix and prevent collisions of products. It can play a good protective role in the transportation and handling of products. In the actual processing of polyurethane sponge, according to the appearance requirements of different products that need to be fixed and protected, it is often necessary to further process the polyurethane sponge material into a certain shape structure. Common processing methods include slitting, grooving and hole opening.

[0003] With the existing polyurethane cutting equipment, most of the equipment can only perform one cutting operation at a time during the cutting process of polyurethane sponge. At the same time, when each polyurethane sponge needs to be cut into multiple pieces, workers are required to adjust the position of the polyurethane sponge after cutting the polyurethane sponge once, and then cut the polyurethane sponge again, which increases the workload of the workers. When a large number of polyurethane sponges need to be cut, the repeated adjustment work not only easily causes fatigue to the workers, resulting in reduced cutting quality of the polyurethane sponge, but also easily affects the cutting efficiency of the polyurethane sponge.

[0004] Therefore, it is necessary to provide a polyurethane sponge cutting device to solve the above-mentioned technical problems. Utility Model Content

Through the setting of the disassembly component, after the fixed limit of the plug plate 18 is released and it is moved to the side away from the mounting plate 5 to be separated from the mounting frame 4, the cutting knife 9 closest to the notch can be quickly disassembled from the separation point between the plug plate 18 and the mounting plate 5, or a new cutting knife 9 can be quickly installed from the notch, so that the number of cutting knives 9 on the device can be conveniently adjusted, thereby improving the practicability of the device.

[0030] A bracket 11 is fixedly connected to the top of the cutting table 1, and the cylinder 3 is fixedly installed on the bracket 11. Slide grooves 12 are provided on both sides of the inner wall of the bracket 11. Guide blocks 13 are slidably connected inside the two slide grooves 12. The opposite sides of the two guide blocks 13 are fixedly connected to the two sides of the mounting frame 4 respectively.

[0031] The fixing assembly includes a fixing pin 14 , which is movably connected to the mounting block 7 , a spring 15 is fixedly connected to the bottom of the fixing pin 14 , and the other end of the spring 15 is fixedly connected to the top of the mounting block 7 .

[0032] The pressing assembly includes two pressing plates 16, which are fixedly connected to the bottom of the fixed plate 8 through a plurality of telescopic rods 20. The outer surfaces of the plurality of telescopic rods 20 are sleeved with springs 17. The pressing plates 16 and the positioning plates 10 do not overlap up and down, so that the bottom of the corresponding pressing plate 16 that moves downward will not abut against the top of the positioning plate 10.

[0033] The disassembly assembly includes an insert plate 18, which is arranged on the mounting frame 4. One end of the insert plate 18 movably extends into the interior of the mounting plate 5.

One side of the push plate 19 is slidably connected to one side of the positioning plate 10. A fixed limiting assembly is arranged on the side of the push plate 19 away from the positioning plate 10. The fixed limiting assembly is a movable fixing rod used to limit the push plate 19 to prevent it from moving during use, thereby improving the cutting quality of the polyurethane sponge.

[0035] Working principle: When working, first adjust the number of cutting knives 9 on the mounting plate 5 according to the cutting quantity of each piece of polyurethane sponge, that is, turn the bolt of the fixed plug plate 18 so that the plug plate 18 is no longer fixed and limited, and then move it to the side away from the mounting plate 5 to separate it from the mounting frame 4, and then remove the cutting knife 9 closest to the separation point of the plug plate 18, that is, pull the fixed latch 14 to move it upward, stretch the spring 15, and separate it from the corresponding fixing groove 6 at its bottom, release the fixation of the mounting block 7, move the mounting block 7, and drive the corresponding cutting knife 9 to move, then remove it from the separation point of the plug plate 18 and the mounting plate 5, or install a new mounting block 7 and cutting knife 9 on the mounting plate 5, thereby completing the adjustment of the number of cutting knives 9;

[0036] After the number of cutting knives 9 is adjusted, the fixing latch 14 can be pulled and the mounting block 7 can be moved to drive the corresponding cutting knives 9 to move. Under the cooperation of the plurality of fixing grooves 6, the spacing of the plurality of cutting knives 9 can be adjusted individually. Then, the polyurethane sponge to be cut is placed on the cutting table 1, and one side of the polyurethane sponge is abutted against the positioning plate 10, and the front or back side is abutted against the push plate 19. Then, the cylinder 3 is started. Under the guidance of the slide groove 12 and the guide block 13, the plurality of cutting knives 9 and the corresponding pressing plates 16 are synchronously moved downward. After the pressing plates 16 are first abutted against the polyurethane sponge, under the cooperation of the spring 2 17 and the telescopic rod 20, the pressing plates 16 can be firmly abutted against the polyurethane sponge. Then, the cutting knives 9 that are moved downward again cooperate with the slot 2, so that different areas of the polyurethane sponge can be cut at one time.

[0037] When the polyurethane sponge is cut and the cutting knife 9 is reset, the fixed limit of the push plate 19 can be released, and the push plate 19 can be moved so that the cut polyurethane sponge can be quickly moved to the front or back of the cutting table 1 under the guidance of the positioning plate 10, thereby quickly unloading the cut polyurethane sponge.
