At the same time, it should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.

[0020] See Figures 1 to 3 As shown, a slitting device for modified polyurethane sponge comprises a slitting table 1 and a support frame 2 installed on the top of the slitting table 1, a slitting roller 3 is rotatably arranged inside the support frame 2, a plurality of slitting pieces 4 are slidably arranged on the slitting roller 3, the slitting pieces 4 and the slitting roller 3 are installed and fixed by fixing pieces, a wide groove 5 corresponding to the slitting roller 3 is also opened on the top of the slitting table 1, a conveying roller 6 is rotatably arranged in the wide groove 5, the slitting piece 4 comprises a supporting ring 21 and a cutting blade 22, the supporting ring 21 is slidably arranged on the slitting roller 3, the cutting blade 22 is fixed on the outer wall of the supporting ring 21, the fixing piece adopts bolts, the supporting ring 21 is fixed on the slitting roller 3 by bolts, when the sponge needs to be slid, the spacing between the supporting rings 21 can be adjusted by the width of the sponge to be cut, the cutting blade 22 is slidably arranged on the slitting roller 3 through the supporting ring 21, and the supporting ring 21 is fixed by bolts when sliding to the specified position.

[0021] Slide grooves 2 19 are provided on both side walls of the support frame 2. The top thread of the support frame 2 is equipped with an adjusting bolt 20. The bottom of the adjusting bolt 20 is rotatably set in the slide groove 2 19. A connecting ring 1 is rotatably set on the slitting roller 3. The bottom of the adjusting bolt 20 is rotatably connected to the connecting ring 1. The slitting roller 3 can be adjusted in height by adjusting the bolt 20. When adjusting the spacing of the support ring 21, it is necessary to first rotate the adjusting bolt 20. The rotation of the adjusting bolt 20 drives the connecting ring 1 to adjust the height, so that the height of the slitting roller 3 is adjusted, thereby preventing the cutting blade 22 from being limited by the conveying roller 1 6 when adjusting the support ring 21 later.

[0022] A plurality of connecting rings 23 are also slidably arranged on the conveying roller 6, and an annular groove 24 corresponding to the cutting blade 22 is opened on the connecting ring 23. The connecting ring 23 is fixed to the conveying roller 6 by bolts. When the position of the slitting piece 4 is adjusted, the corresponding connecting ring 23 will also be adjusted accordingly so that the annular groove 24 on the connecting ring 23 can correspond to the cutting blade 22, thereby preventing the cutting blade 22 from directly cutting the conveying roller 6 during cutting.

[0023] A support plate 7 is symmetrically fixed on the side wall of the slitting table 1 close to the support frame 2. The support plate 7 is a concave structure. A conveying roller 2 8 is rotatably arranged between the two support plates 7, and a conveying roller 3 9 is slidably arranged between the two support plates 7. A driving component 10 for driving the slitting roller 3, the conveying roller 1 6 and the conveying roller 2 8 is also arranged on the side wall of the slitting table 1. When the sponge needs to be cut, the sponge is first inserted between the conveying roller 1 6 and the slitting roller 3. At this time, the driving component 10 can be started to rotate the conveying roller 1 6 and the slitting roller 3 to promote the sponge to be conveyed and thus achieve cutting.

[0024] The driving assembly 10 includes two gears 11, two sprockets 12 and sprocket 2 13. One end of the slitting roller 3 and the conveying roller 1 6 respectively penetrates the support frame 2 and the slitting table 1. The two gears 11 are respectively fixed on the slitting roller 3 and the conveying roller 1 6, and the two gears 11 are meshed. One end of the conveying roller 2 8 penetrates the support plate 7. The two sprockets 12 are respectively fixed on the conveying roller 1 6 and the conveying roller 2 8. A driving motor 14 is also installed inside the slitting table 1. The output shaft of the driving motor 14 passes through the slitting table 1 and is fixed to the sprocket 2 13. When starting the driving assembly 10, the driving motor 14 can be started first. The output shaft of the driving motor 14 will drive the sprocket 2 13 to rotate, and the sprocket 12 and A chain 15 is connected between the sprockets 13, and the sprockets 1 12 and the sprockets 13 are connected by the chain 15. The sprockets 13 will drive the two sprockets 12 to rotate through the chain 15. The rotation of the sprocket 12 on one side will drive the conveying roller 6 to rotate, and the conveying roller 6 will drive the gear 11 to rotate. After the adjustment of the support ring 21 is completed, the slitting roller 3 will be reset to a high level and the meshing of the two gears 11 will be ensured again. The gear 11 on the conveying roller 6 will drive the gear 11 on the slitting roller 3 to rotate, thereby realizing the rotation of the conveying roller 6 and the slitting roller 3, so as to push the sponge between the two rollers and cut it by the cutting blade 22.

[0025] The cut sponge will enter between the conveying roller 2 8 and the conveying roller 3 9, and the conveying roller 2 8 will be rotated through the sprocket 2 13. The rotation of the conveying roller 2 8 will push the cut sponge away from the slitting roller 3, and the conveying roller 2 8 and the conveying roller 3 9 will cooperate to better promote the movement of the sponge.

[0026] A slide groove 16 is provided on the upper inner wall of the support plate 7, and connecting plates 17 are slidably arranged in the two slide grooves 16. The conveying roller 39 is rotatably arranged on the connecting plate 17, and a spring 18 is installed in the slide groove 16. One end of the spring 18 is fixed to the bottom of the slide groove 16, and the other end of the spring 18 is fixed to the connecting plate 17. Due to different requirements, the thickness of the cut sponge will also change. In order to better convey the sponge, the conveying roller 39 is designed to be a height-adjustable structure. When the thicker sponge passes through the conveying roller 2 8 and the conveying roller 3 9, the sponge will lift the top conveying roller 3 9, so that the spring 18 generates elastic force. When the sponge is conveyed away, the conveying roller 39 is convenient to drive the connecting plate 17 to reset through the spring 18, thereby realizing the conveying of sponges of different thicknesses.

[0027] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect.
