[0002] Sponge is a porous material with good water absorption and can be used to clean items. It is generally made of wood cellulose fibers or foamed plastic polymers. There are also natural sponges made from sponge animals. In addition, there are three types of synthetic sponges made of other materials, namely low-density polyether (non-absorbent sponge), polyvinyl alcohol (highly absorbent material without obvious pores) and polyester.

[0003] After the sponge is produced, it needs to be processed into various types of sponge products according to its purpose. At this time, a corresponding sponge pressing machine is needed. However, the existing sponge pressing machines are limited by structure and design in actual use. Most of the molds of the pressed sponge are connected to the rotating shaft of the motor using bolts, etc., and different types of sponge products require different molds for pressing and molding. The molds fixed with bolts are very troublesome to disassemble, and the operator needs to use corresponding tools to repeatedly tighten and loosen the bolts, which is not only time-consuming and laborious, but also affects the efficiency of sponge processing. Therefore, improvements are needed. Utility Model Content

[0052] The working principle and use process of this utility model:

[0053] First, the operator starts the driving motor 501, so that the driving shaft 502 drives the rotating disk 503 to rotate, so that the two connecting rods 405 hinged to the rotating disk 503 respectively generate a thrust on the first fixed box 403 and the second fixed box 404, pushing the first fixed box 403 with the first short card block 9 and the first long card block 15, and the second fixed box 404 with the second short card block 11 and the second long card block 17 to move in opposite directions, so that the first short card block 9 and the second short card block 11, the first long card block 15 and the second The long clamping block 17 releases the lock on the upper mold 10 and the lower mold 16 in turn, and then the operator can use it to remove the upper mold 10 and the lower mold 16, and replace the upper mold 10 and the lower mold 16 with different specifications, and then start the drive motor 501, so as to lock the new upper mold 10 and the lower mold 16 in turn, and then the operator starts the pneumatic cylinder 26 to align the blade 27 with the middle position of the upper mold 10 and the lower mold 16, so that the mold can be quickly disassembled and replaced, thereby improving the convenience of the sponge pressing machine.

[0054] Then the operator starts the first motor 6, so that the rotating shaft 7 rotates with the driving gear 8, the first short block 9 and the upper mold 10. At this time, the driven gear 13 meshing with the driving gear 8 will rotate in the opposite direction with the lower mold 16 through the round rod 14 and the first long block 15. Then the operator starts the second motor 22, so that the threaded rod 23 rotates, so that the rectangular block 24 threadedly sleeved with the threaded rod 23 moves downward with the bottom ends of the two connecting rods 25, and then the top ends of the two connecting rods 25 respectively generate a pulling force on the two sliders 20, pulling the two sliders 20 to move towards each other with the two guide blocks 21 until the spacing between the two guide blocks 21 matches the width of the sponge. Then the operator can push the sponge, so that the sponge is pressed and formed under the action of the upper mold 10 and the lower mold 16, and is cut into two symmetrical halves when passing through the blade 27. The mutual cooperation of various mechanisms realizes the auxiliary positioning of the sponge, so that the operator does not need to manually support it, avoiding injuries to the operator.
