[0002] In the production process of lightweight sponges, it is necessary to punch holes in the sponge to form regular or irregular pore structures to meet production requirements.

[0003] However, when traditional mechanical punching machines process lightweight sponges, the sponges themselves are low in density, light in weight, and soft in texture. During the process of the punching head penetrating the sponge at high speed and quickly retracting, the friction between the punching head and the sponge, as well as the elastic recovery force of the sponge material itself, can easily cause the sponge to shift, affecting the processing accuracy. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-3A lightweight sponge punching device includes a body 1. A working plate 5 is mounted on the upper part of the body 1 via a movable plate 3. Pressure plates 8 are rotatably mounted on both sides of the working plate 5 via pins. A connecting plate 82 is mounted at an incline on the bottom of the pressure plate 8. A connecting rope 61 is connected to the bottom of each connecting plate 82. The other end of each connecting rope 61 is wound around a pulley 6. The pulley 6 is mounted on the bottom of the working plate 5 via a mounting seat.

[0023] The upper part of the working plate 5 has multiple air holes 51. The bottom of the air holes 51 is connected to the connecting pipe 22. One end of the connecting pipe 22 is connected to the air pump 2 through the air pipe 21.

[0024] An air pump 2 is installed on one side of the machine body 1. The air inlet of the air pump 2 is connected to an air pipe 21. The air pump 2 draws gas from the connecting pipe 22 through the air pipe 21 and generates negative pressure at the air hole 51 of the working plate 5 to produce a slight adsorption force on the sponge.

[0025] A cylinder 11 is installed on the upper part of the machine body 1. The telescopic rod of the cylinder 11 faces downward and is connected to a stamping plate 12. The cylinder 11 extends to realize the vertical movement of the stamping plate 12. A pair of punch heads 13 are installed at the bottom of the stamping plate 12 to realize the punching operation.

[0026] An electric lead screw moving mechanism 4 is provided in the middle of the body 1. The output moving end of the electric lead screw moving mechanism 4 is connected to the moving plate 3. The electric lead screw moving mechanism 4 realizes the lateral movement of the moving plate 3. A punching head 13 is arranged on the top of the moving plate 3.

[0027] A pulley 6 is rotatably mounted on the bottom center of the working plate 5 via a mounting base. A pair of connecting ropes 61 are symmetrically connected to the outer wall of the pulley 6 from top to bottom. When the pulley 6 rotates, the connecting ropes 61 are wound around the outer wall of the pulley 6.

[0028] Adjacent connecting ropes 61 are staggered on the outer wall of the pulley to avoid interference between adjacent connecting ropes 61.

[0029] A rubber band 81 is installed on the upper end of the pressure plate 8, and a torsion spring 83 is installed at the rotating connection between the pressure plate 8 and the working plate 5. When the working plate 5 rotates, the torsional force generated by the deformation of the torsion spring 83 will drive the working plate 5 to rotate and reset.

[0030] Under normal conditions, with the torsion spring 83 in place, the pressure plate 8 always generates a torsional force that deflects toward the working plate 5, that is, the pressure plate 8 covers the working plate 5.

[0031] A rocker arm 7 is fixedly connected to one side of the middle part of the pulley 6, and the pulley 6 is rotated by the rocker arm 7.

[0032] In this embodiment, the rocker arm 7 is manually rotated to drive the pulley 6 to rotate. During the rotation of the pulley 6, the two connecting ropes 61 are pulled and wound, causing the other end of the connecting ropes 61 to retract and move inward. The pressure plate 8 connected to the connecting ropes 61 then deflects. After the pressure plate 8 rotates, it drives the torsion spring 83 to deform. After the pressure plate 8 rotates and opens, the sponge material is placed on the working plate 5. At this time, the rocker arm 7 is released. Under the reset action of the torsion spring 83, the pressure plate 8 deflects and resets. The rubber band 81 then slightly presses down on the upper wall of the sponge to achieve a limiting effect.

[0033] When the pressure plate 8 is reset and rotated, the connecting plate 82 at its bottom will rotate accordingly. The resulting displacement will pull the connecting rope 61, causing the connecting rope 61 to stretch and move outward. The other end of the connecting rope 61 will drive the pulley 6 to rotate and reset adaptively.

[0034] It is worth noting that the pressure plate 8 is in a depressed state in its natural state, and the connecting rope 61 is in a taut and straight state.

[0035] After the material is fed, the cylinder 11 is controlled by the machine body 1 to run. The cylinder 11 drives the punching head 13 to move downward to punch the sponge. The specific punching process is common knowledge to those skilled in the art and will not be explained further.

[0036] Synchronously, the machine body 1 controls the operation of the air pump 2. The air pump 2 draws gas from the connecting pipe 22 through the air pipe 21 and generates negative pressure at the air hole 51 of the working plate 5 to generate a slight adsorption force on the bottom of the sponge, thereby ensuring the stable installation of the sponge.

[0037] It should be noted that the sponge material itself has complex pores. When it is subjected to negative pressure adsorption, these pores generate flow resistance to meet the negative pressure adsorption. The more specific adsorption principle will not be explained here, as it is common knowledge to those skilled in the art.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
