At this time, the debris falls into the collection tank through the leakage holes and cavities. After the debris accumulates in the collection tank, the slider slides along the slide rail through the telescopic mechanism. When the slider slides, it drives the fixed bar to slide. When the fixed bar slides, the cleaning brush at the bottom cleans the material debris in the collection tank. The collection tank is convenient for collecting material debris, and then the staff will handle it uniformly, which is convenient for the staff to take care of it. BRIEF DESCRIPTION OF THE DRAWINGS

The linkage block 203 is slidably connected to the sliding groove 202. The connecting block 204 forms a lifting structure along the sliding groove 202 through the cooperation between the hydraulic rod 209 and the linkage block 203. A plurality of telescopic connecting rods 205 are provided, and the telescopic connecting rods 205 are evenly distributed along the horizontal direction of the connecting block 204. The auxiliary strip 206 is annularly coated on the outer surface of the telescopic connecting rod 205. The outer surfaces of both ends of the auxiliary strip 206 are fixedly connected to the placing pedestal 207 and the connecting block 204. The placing pedestal 207 forms a telescopic structure with the connecting block 204 through the cooperation between the auxiliary strip 206 and the telescopic connecting rod 205.

The cutting seat 301 and the cutting knife 208 are arranged in parallel. The limit end 210 is horizontally arranged on the top outer surface of the sliding groove 202. The cutting seat 301 is symmetrically distributed on both sides of the connecting plate 3. The connecting plate 3 is fixedly connected to one side of the top of the workbench 101. The memory spring 304 is evenly distributed along the horizontal direction of the movable groove 302.

The outer surfaces of the two sets of cleaning sheets 308 are tightly fitted together. The guide block 309 is arranged above the fixed end 306, and the guide block 309 is inclined at 60 degrees. First, when the device is used, the PVC material roll is placed on the cutting seat 301 above the device workbench 101, and the hydraulic rod 209 drives the top connecting block 204 to be lifted and lowered by its own lifting. When the connecting block 204 is lifted and lowered, the linkage blocks 203 fixed on both sides slide along the vertical direction of the sliding groove 202, so that the connecting block 204 can maintain the vertical direction when lifting and lowering, and the sliding groove 202 limits the connecting block 204, and the top limiting end 210 prevents the connecting block 204 from being lifted and lowered. When the cutting blade 208 is moved to the middle of the two cutting seats 301, the cutting blade 208 is aligned with the cutting position to start working. When the cutting is finished, the telescopic link 205 controls the cutting blade 208 to move back to the side of the connecting block 204. When the cutting blade 208 is above the cutting seat 301, the hydraulic rod 209 controls the connecting block 204 to start descending, so that the cutting blade 208 starts cutting. When the cutting blade 208 cuts the PVC material and enters the inside of the cutting blade 208 on both sides,The cleaning sheet 308 is driven to tilt downward, and the cleaning sheet 308 drives the fixing strip 307 and the fixed end 306 downward.

When the cutting knife 208 rises, the cleaning sheets 308 on both sides downward block the PVC material adsorbed on the cutting knife 208, so that the material can be directly separated after being cut and will not be taken out by the cutting knife 208. When the cutting knife 208 leaves the bottom of the cleaning sheet 308, the rebound strip 305 cooperates with the memory spring 304 to make the fixed end 306 rebound to the original position, thereby starting the next cutting work.

[0031] A leakage hole 4 is provided on the top outer surface of the workbench 101, a cavity 401 is provided at the bottom of the leakage hole 4, a collecting groove 402 is provided at the bottom of the cavity 401, slide rails 403 are fixedly connected to the inner surfaces of both sides of the collecting groove 402, a telescopic mechanism 404 is movably connected to the inner surface of one side of the slide rail 403, a slider 405 is fixedly connected to the outer surface of one side of the telescopic mechanism 404, a fixing bar 406 is fixedly connected to the inner surface of one side of the slider 405, and a cleaning brush 407 is fixedly connected to the outer surface of the bottom end of the fixing bar 406;

[0032] The leak hole 4 is opened through the top of the leak hole 4, and there are several leak holes 4. The cavity 401 is opened at the top of the device body 1. The collection tank 402 is connected to the workbench 101 through the cavity 401 and the leak hole 4. The slide rails 403 are symmetrically distributed on the inner surfaces of both sides of the collection tank 402. The slider 405 is a telescopic structure with the slide rail 403 through the telescopic mechanism 404. The slider 405 and the slide rail 403 are slidably connected. The inner surface of the slide rail 403 is tightly fitted with the outer surface of the slider 405. The sliders 405 are symmetrically distributed on the outer surfaces of both sides of the fixing bar 406. The fixing bar 406 is placed parallel to the inside of the collection tank 402. The cleaning brush 407 is evenly distributed along the horizontal direction of the fixing bar 406. The material debris in the collecting tank 402 is evenly distributed, and the outer surface of the bottom end of the cleaning brush 407 fits tightly with the inner surface of the bottom end of the collecting tank 402. After the cutting work is completed, some of the debris left during cutting remains on the workbench 101. At this time, the debris falls into the collecting tank 402 through the leakage hole 4 and the cavity 401. After the debris accumulates in the collecting tank 402, the slider 405 slides along the slide rail 403 through the telescopic mechanism 404. The slider 405 drives the fixed bar 406 to slide when sliding. When the fixed bar 406 slides, the cleaning brush 407 at the bottom cleans the material debris in the collecting tank 402. The collecting tank 402 is convenient for collecting material debris, and then the staff will carry out unified processing, which is convenient for the staff to take care of.

[0033] Working principle: First, when the device is used, the PVC material roll is placed on the cutting seat 301 above the device workbench 101, and the hydraulic rod 209 drives the top connecting block 204 to rise and fall through its own lifting. When the connecting block 204 is lifted, the linkage blocks 203 fixed on both sides slide along the vertical direction of the sliding groove 202, so that the connecting block 204 can maintain the vertical direction during lifting, and the sliding groove 202 limits the connecting block 204. The top limit end 210 prevents the connecting block 204 from rising excessively. The linkage block 203 cooperates with the connecting block 204 to make the multiple sets of telescopic connecting rods 205 more stable during work. The telescopic connecting rods 205 cooperate with the auxiliary strips 206 to extend and retract the placing platform 207. When the placing platform 207 is extended and retracted, it drives the cutting knife 208 at the bottom to move, so that the cutting knife 208 moves to the middle of the two sets of cutting seats 301, so that it is aligned with the cutting position to officially start working. When the cutting is finished, the telescopic connecting rod 205 controls the cutting knife 208 to move back to one side of the connecting block 204. When the cutting knife 208 is above the cutting seat 301, the hydraulic rod 209 controls the connecting block 204 to start to descend, so that the cutting knife 208 starts to cut. When the cutting knife 208 cuts the PVC material and enters the inside of the cutting knives 208 on both sides, it drives the cleaning piece 308 to tilt downward. The cleaning piece 308 drives the clamping strip 307 and the fixed end 306 downward. When the fixed end 306 moves downward, it moves together through the memory spring 304 and the rebound strip 305. When the cutting knife 208 rises, the downward cleaning pieces 308 on both sides block the PVC material adsorbed on the cutting knife 208, so that the material can be directly separated after being cut and will not be taken out by the cutting knife 208. When the cutting knife 208 leaves the bottom of the cleaning piece 308, the rebound strip 305 cooperates with the memory spring 304 to make the fixed end 306 rebound to the original position, thereby starting the next cutting work;

[0034] Then, after the cutting work is completed, some of the debris left over from the cutting remains on the workbench 101. At this time, the debris falls into the collecting tank 402 through the leak hole 4 and the cavity 401. After the debris accumulates in the collecting tank 402, the slider 405 slides along the slide rail 403 through the telescopic mechanism 404. The slider 405 drives the fixed bar 406 to slide when sliding. When the fixed bar 406 slides, the cleaning brush 407 at the bottom of the fixing bar 406 cleans the material debris in the collecting tank 402. The collecting tank 402 is convenient for collecting the material debris, which is then uniformly processed by the staff, making it easy for the staff to take care of it.
