[0025] This specific embodiment is a longitudinal cutting device for polypropylene backing cloth, and its structural schematic diagram is as shown in Figure 1 , Figure 2 , Figure 3 ,Figure 4 As shown in the figure, it includes a workbench 1 and a protection component 2. An installation plate 11 is installed at the middle position on the side of the workbench 1. A cylinder 13 penetrates through the top of the installation plate 11. A chute 14 is opened inside the installation plate 11. The lower end of the cylinder 13 is connected to a lifting block 12. A sliding plate 9 is connected to the side of the lifting block 12. A cutting blade 15 is slidably connected to the sliding plate 9. The upper surface of the lifting block 12 is fixedly connected to the cylinder 13. The lifting block 12 is slidably connected to the chute 14. A second motor 10 is installed on the side of the lifting block 12. The output end of the second motor 10 rotates through the lifting block 12. The output end of the second motor 10 is fixedly connected to the sliding plate 9. A scale line 16 is opened on the upper surface of the sliding plate 9. Two groups of symmetrically distributed limiting grooves 17 are opened on both sides of the sliding plate 9. A chassis 6 is installed at the lower part of the workbench 1. Two vertical plates 3 are installed at both ends of the upper surface of the workbench 1. A first motor 7 is installed on the side of a group of vertical plates 3. The first motor 7 is connected to a rotating roller 8. A driven roller 5 is rotatably connected to a group of vertical plates 3. A box body 4 is installed on the side of the workbench 1 away from the first motor 7 by threading. The protection component 2 is placed inside the box body 4. Two groups of symmetrically distributed clamping plates 18 are threaded on both sides of the cutting blade 15. A clamping groove 19 is opened in the cutting blade 15 and the clamping plate 18. The clamping groove 19 is adapted to the sliding plate 9 and the limiting groove 17. A bolt 20 is threaded through the side of the clamping plate 18. When actually performing the longitudinal cutting of the polypropylene felt cloth, first, according to the width of the polypropylene felt cloth after longitudinal cutting, use the protection component 2 to correspondingly install the cutting blade 15 and adjust the distance between the cutting blades 15. The scale line 16 is used to assist in observing the moving distance of the cutting blade 15. When the position of the cutting blade 15 is appropriate, remove the protection component 2 and use the bolt 20 to tighten against the side of the sliding plate 9. At this time, the position of the cutting blade 15 is fixed. Then, place the polypropylene felt cloth on the driven roller 5, pull out the polypropylene felt cloth and connect it to the rotating roller 8. Start the cylinder 13 to drive the lifting block 12 to move downward along the chute 14. The downward movement of the lifting block 12 drives the sliding plate 9 and the second motor 10 to move downward. The downward movement of the sliding plate 9 drives the cutting blade 15 and the clamping plate 18 to move downward. When the cutting blade 15 cuts through the polypropylene felt cloth, start the first motor 7 and the second motor 10. The start of the first motor 7 drives the rotating roller 8 to rotate. The rotation of the rotating roller 8 drives the polypropylene felt cloth to pass through the cutting blade 15. The rotation of the second motor 10 drives the sliding plate 9 to rotate. The rotation of the sliding plate 9 drives the cutting blade 15 to rotate to cut the polypropylene felt cloth.

[0026] Refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5As shown, the protection component 2 includes a first protection plate 201. Plug rods 206 are installed on both sides of the first protection plate 201. The first protection plate 201 is movably engaged with a second protection plate 202 through the plug rods 206. A jack 203 adapted to the plug rods 206 is provided in the second protection plate 202. The plug rods 206 and the jacks 203 are magnetically adapted. Handles 207 are installed on the sides of the first protection plate 201 and the second protection plate 202. Slots 204 are provided in the first protection plate 201 and the second protection plate 202, and the slots 204 are adapted to the cutting blades 15. Circular holes 205 adapted to the clamping plates 18 are provided at the middle positions of the first protection plate 201 and the second protection plate 202. The first protection plate 201 and the second protection plate 202 are aligned with the cutting blades 15 and snapped in through the handles 207 (at this time, the plug rods 206 are inserted into the jacks 203, and the plug rods 206 and the jacks 203 are magnetically arranged, and when the plug rods 206 are inserted into the jacks 203, there is a certain limiting effect). Among them, the cutting blades 15 are inside the slots 204, and the clamping plates 18 are at the circular holes 205. Both hands press the handles 207 towards the middle to lift the cutting blades 15 and the clamping plates 18 and align them with the sliding plate 9 and snap them in.

[0027] Working principle: When actually longitudinally cutting the polypropylene felt cloth, first, according to the width of the polypropylene felt cloth after longitudinal cutting, the protection component 2 is used to correspondingly install the cutting blades 15 and adjust the distance between the cutting blades 15. Specifically, the box body 4 is opened to take out the protection component 2. The first protection plate 201 and the second protection plate 202 are aligned with the cutting blades 15 and snapped in through the handles 207 (at this time, the plug rods 206 are inserted into the jacks 203, and the plug rods 206 and the jacks 203 are magnetically arranged, and when the plug rods 206 are inserted into the jacks 203, there is a certain limiting effect). Among them, the cutting blades 15 are inside the slots 204, and the clamping plates 18 are at the circular holes 205. Both hands press the handles 207 towards the middle to lift the cutting blades 15 and the clamping plates 18 and align them with the sliding plate 9 and snap them in. The auxiliary observation of the moving distance of the cutting blades 15 is carried out through the scale lines 16. When the positions of the cutting blades 15 are appropriate, the protection component 2 is removed, and the side of the sliding plate 9 is tightened with bolts 20. At this time, the positions of the cutting blades 15 are fixed. Subsequently, the cutting blades 15 are continuously installed. When the positions of the cutting blades 15 need to be adjusted, the bolts 20 are used to release the limitation on the cutting blades 15, and then the protection component 2 is used to move the cutting blades 15. Through the setting of the protection component 2, when the cutting blades 15 need to be moved, the protection of the cutting blades 15 is realized, thereby preventing the hands of the operators from accidentally touching the cutting blades 15 when moving the cutting blades 15 and causing the hands to be cut, and improving the operation safety;

[0028] Subsequently, place the polypropylene felt cloth on the driven roller 5, pull out the polypropylene felt cloth and connect it to the rotating roller 8 (the section of the polypropylene felt cloth between the rotating roller 8 and the cutting blade 15 is not cut off, and all subsequent polypropylene felt cloth will be cut off). Start the cylinder 13 to drive the lifting block 12 to move downward along the sliding groove 14. The downward movement of the lifting block 12 drives the sliding plate 9 and the second motor 10 to move downward. The downward movement of the sliding plate 9 drives the cutting blade 15 and the clamping plate 18 to move downward. When the cutting blade 15 cuts through the polypropylene felt cloth, start the first motor 7 and the second motor 10. The start of the first motor 7 drives the rotating roller 8 to rotate. The rotation of the rotating roller 8 drives the polypropylene felt cloth to pass through the cutting blade 15. The rotation of the second motor 10 drives the sliding plate 9 to rotate. The rotation of the sliding plate 9 drives the cutting blade 15 to rotate to cut the polypropylene felt cloth. Through the mounting plate 11 arranged on the side, the line of sight blocking of the cutting blade 15 is prevented, so that when installing and adjusting the position of the cutting blade 15, it is convenient for the operators to observe and the safety is improved.
