[0011] Preferably, the method for using the plastic sheet heat cutting machine comprises the following steps:

[0012] S1: Place the plastic plate on top of the processing plate, and the hot cutting machine frame moves along the plastic plate driven by the electric slide, and laser cutting is performed along the center line of the plastic plate driven by the hot cutting machine. After the plastic plate is cut, the pushing plate drives the plate to move toward the direction of the transverse groove under the drive of the pushing electric cylinder. When the pushing plate continues to move the plate, the moving frame at the bottom of the pushing plate will move synchronously. When the moving frame moves, the notch in the upper limit block of the pushing plate abuts against the block on the limit frame, and then when the moving frame continues to move, the pushing plate is limited by the limit frame so that the pushing plate cannot move. At the same time, the pressure spring between the moving frame and the pushing plate gradually accumulates force. When the pushing plate moves the cut plastic plate to the transverse groove on the processing plate, the wedge block on the moving frame will contact the inclined part of the limit frame. At this time, the wedge block squeezes the limit frame so that the limit frame is When the two expansion plates are separated by the drive of the rotating frame, the two side plates will push the cut plastic plate in the opposite direction.

[0013] S2: When the push electric cylinder drives the push plate to move and reset, the push plate resets and drives the moving frame to move. When the moving frame moves, it will synchronously drive the push plate to move under the connection of the pressure spring. The push plate will pull the sliding plate to move the two unfolding plates to reset to a close state. When the push plate moves, the inclined surface of the upper limit block of the push plate will contact the block on the limit frame, and the block on the limit frame will not limit the block, so that the push plate moves and resets under the drive of the moving frame. After the push plate moves and resets, the notch on the limit block set will re-contact the block on the limit frame, so that when the next plastic plate is pushed by the push plate, the cut plastic plate can be continuously separated;

[0014] S3: When the plastic plate is placed on the processing plate, the electric slide drives the hot cutting frame to move along the plastic plate, and the hot cutting frame drives the hot cutting machine to cut the plastic plate. When the hot cutting frame moves, the hot cutting frame drives the carrying frame to move. The carrying frame moves through the fixed rod on the carrying frame and contacts the inclined groove on the adjusting frame. At this time, the adjusting frame is pressed down under the restriction of the inclined groove and the fixed rod. After the adjusting frame is pressed down, the lower pressing frame is pressed down to press and limit the plastic plate, so that the separated plastic plate can be stably cleaned under the limit of the lower pressing frame.

[0015] S4: After cutting, the plastic sheet is expanded outward through the expansion mechanism, and the plastic sheet moves toward the cleaning part. The outer wall of the plastic sheet squeezes the telescopic cleaning scraper. The bottom of the cleaning scraper is inclined so that the plastic sheet can drive the cleaning scraper to lift upward. At this time, the cleaning scraper shrinks, and then the plastic sheet is moved between the two cleaning scrapers on the support frame under the drive of the side plate. At this time, when the hot cutting frame cuts another group of plastic sheets on the processing plate, the hot cutting frame drives the supporting frame to move, and the supporting frame drives the supporting frame to make the two cleaning scrapers clean and scrape the processed part of the plastic sheet;

[0016] S5: After the hot cutting frame cuts another group of plastic plates on the processing plate, the hot cutting frame will be reset under the drive of the electric slide, and the hot cutting frame will drive the load-bearing frame to move and reset when it is reset, and the load-bearing frame will drive the lower pressure frame to move up and reset, and at the same time the load-bearing frame moves, the positioning tooth plate on the load-bearing frame contacts with the first rotating gear, and the positioning tooth plate will drive the first rotating gear to rotate, and when the first rotating gear rotates, it will drive the one-way shaft to rotate, which will cause the second rotating gear to rotate, and the second rotating gear will drive the pushing tooth plate to move, and after the pushing tooth plate moves, it will drive the side push frame to push the cleaned plastic plate to the transverse groove, so that the next group of plastic plates can enter the two cleaning scrapers when they move to the transverse groove, and when the hot cutting frame cuts the plastic plate again with the hot cutting machine, when the load-bearing frame moves, when the load-bearing frame moves and drives the cleaning member to clean the plastic plate, due to the one-way shaft, the second rotating gear will not drive the pushing tooth plate to move, and thus the side push frame will not push the plastic plate being cleaned.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] In the present invention, when the push plate pushes the cut plastic plate toward the direction of the transverse groove, the plastic plate will be stuck between two side plates close to each other because the plastic plate is cut along its center line. When the two unfolding plates are separated under the drive of the rotating frame, the two side plates will push the cut plastic plate toward opposite directions. After the plastic plate is cut by the hot cutting machine, the surface of the outer wall of the plastic plate contains residues. After the cut plastic plate is separated, the plastic plate can be further processed by the limiting mechanisms on both sides of the transverse groove, and the two cut plates can be processed separately, thereby improving the efficiency of plastic plate processing.

[0019] In the present invention, when the cut plastic plate is moved toward the transverse groove by the pushing mechanism, the plastic plate is separated and moved toward the two limiting mechanisms after reaching the designated position, so that the plastic plate can be processed by the two limiting mechanisms respectively.

[0020] In the present invention, the hot cutting frame drives the carrier frame to move, and the carrier frame drives the support frame to make two cleaning scrapers clean and scrape the processed part of the plastic plate, thereby scraping off the residual impurities on the cut part of the plastic plate and cleaning the surface of the plastic plate after cutting.

[0021] In the present invention, the positioning tooth plate on the carrier is in contact with the first rotating gear, and the positioning tooth plate will drive the first rotating gear to rotate. When the first rotating gear rotates, it will drive the one-way shaft to rotate, which will cause the second rotating gear to rotate. The rotation of the second rotating gear will drive the pushing tooth plate to move. After the pushing tooth plate moves, it will drive the side pushing frame to push the cleaned plastic plate to the horizontal groove, so that the next group of plastic plates can enter the two cleaning scrapers when they move to the horizontal groove.

[0037] The plastic plate is placed on the top of the processing plate 12, and the hot cutting frame 16 moves along the plastic plate under the drive of the electric slide 15. The laser cutting operation is performed along the center line of the plastic plate under the drive of the hot cutting machine 17. After the plastic plate is cut, the pushing plate 21 drives the plate to move toward the direction of the transverse groove 13 under the drive of the pushing electric cylinder 14. When the pushing plate 21 continues to move the plate, the moving frame 22 at the bottom of the pushing plate 21 will move synchronously. When the moving frame 22 moves, the notch 210 in the upper limit block 29 of the pushing plate 23 abuts against the stopper 212 on the limit frame 27, and then when the moving frame 22 moves, the notch 210 in the upper limit block 29 of the pushing plate 23 abuts against the stopper 212 on the limit frame 27. When the moving frame 22 continues to move, the pushing plate 23 is limited by the limiting frame 27 so that the pushing plate 23 cannot move. At the same time, the pressure spring 25 located between the moving frame 22 and the pushing plate 23 gradually accumulates force. When the pushing plate 21 moves the cut plastic plate to the transverse groove 13 on the processing plate 12, the wedge-shaped block 213 on the moving frame 22 will contact the inclined part of the limiting frame 27. At this time, the wedge-shaped block 213 squeezes the limiting frame 27 to lift the limiting frame 27 upward on the support rod 26. After the limiting frame 27 is lifted, the stopper 212 on the limiting frame 27 will contact the notch 21 on the limiting block 29. 0 separation, at this time, the pressure spring 25 after accumulating force will quickly push the push plate 23, when the push plate 23 moves, the push plate 23 will drive the sliding plate 31 to move, the sliding plate 31 moves so that the rack 32 can drive the rotating gear 34 to rotate, the rotating gear 34 rotates and drives the rotating rod 33 to rotate, the rotating frame 35 on the rotating rod 33 will expand outward in the accommodating chamber 11, and the sliding groove 36 provided on the rotating frame 35 will drive the clamping wheel 39 to move, so that the clamping rod 38 on the clamping wheel 39 can drive the two unfolding plates 37 that are close to each other to separate, and the push plate 21 will cut the plastic plate When pushed in the direction of the transverse groove 13, the plastic plate is cut along its center line, and the plastic plate will be stuck between the two side plates 310 that are close to each other. When the two unfolding plates 37 are separated under the drive of the rotating frame 35, the two side plates 310 will push the cut plastic plate in opposite directions. After the plastic plate is cut by the hot cutting machine 17, the surface of the outer wall contains residues. After the cut plastic plate is separated, the limiting mechanism 4 on both sides of the transverse groove 13 can be used to further process the plastic plate, and the two cut plates can be processed respectively, thereby improving the efficiency of plastic plate processing.

[0038] When the push cylinder 14 drives the push plate 21 to move and reset, the push plate 21 resets and drives the moving frame 22 to move. When the moving frame 22 moves, it will synchronously drive the push plate 23 to move under the connection of the pressure spring 25. The push plate 23 will pull the sliding plate 31 to move the two unfolding plates 37 to reset to a close state. When the push plate 23 moves, the inclined surface 211 of the upper limit block 29 of the push plate 23 will contact the stop block 212 on the limit frame 27, and the stop block 212 on the limit frame 27 will not limit the stop block 29, thereby making the push plate 23 is moved and reset under the drive of the moving frame 22. After the pushing plate 23 is moved and reset, the notch 210 on the limit block 29 set will re-contact the stop block 212 on the limit frame 27, so that when the next plastic plate is pushed by the pushing plate 21, the cut plastic plate can be continuously separated. Through this arrangement, when the cut plastic plate moves toward the direction of the transverse groove 13, the plastic plates are separated and moved toward the directions of the two limit mechanisms 4 after reaching the specified position, so that the plastic plates can be subsequently processed by the two limit mechanisms 4 respectively.

[0039] In this embodiment, Figure 1 , Figure 2 , Figure 7 , Figure 8 and Fig. 9 As shown, the two limiting mechanisms 4 each include a limiting seat 41 fixedly arranged on the top of the processing plate 12, a bearing frame 42 is horizontally slidably arranged on the limiting seat 41, a fixing rod 43 is fixedly connected to the bearing frame 42, and an adjusting frame 44 is longitudinally slidably arranged on the limiting seat 41, an inclined groove 45 is provided on the adjusting frame 44, and the fixing rod 43 extends toward the inclined groove 45, and a lower pressing frame 46 is fixedly arranged on the adjusting frame 44, and the lower pressing frame 46 is composed of a telescopic plate, and the lower pressing frame 46 is located above the horizontal groove 13 on the processing plate 12, and the bearing frame 42 is connected to the hot cutting frame 16;

[0040] When the plastic plate is placed on the processing plate 12, the electric slide 15 drives the hot cutting frame 16 to move along the plastic plate, and the hot cutting frame 16 drives the hot cutting machine 17 to cut the plastic plate. When the hot cutting frame 16 moves, the hot cutting frame 16 will drive the supporting frame 42 to move. The supporting frame 42 moves through the fixed rod 43 on the supporting frame 42 and contacts with the inclined groove 45 on the adjusting frame 44. At this time, the adjusting frame 44 will be pressed down under the restriction of the inclined groove 45 and the fixed rod 43. After the adjusting frame 44 is pressed down, the lower pressing frame 46 will be pressed down to press and limit the plastic plate, so that the separated plastic plate can be stably cleaned under the limitation of the lower pressing frame 46.

[0041] In this embodiment, Figure 1 , Figure 2 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 As shown, the carrier 42 is also provided with a cleaning member 5, and the cleaning member 5 includes a support frame 51 fixedly connected to the outer wall of the carrier 42, and cleaning scrapers 52 are provided at the bottom of both sides of the support frame 51, and a friction layer is provided on the inner wall of the cleaning scraper 52, and the two cleaning scrapers 52 are elastically retractable;

[0042] After cutting, the plastic plate is expanded outward through the expansion mechanism 3, and the plastic plate moves toward the cleaning member 5. The outer wall of the plastic plate squeezes the telescopic cleaning scraper 52. The bottom of the cleaning scraper 52 is inclined so that the plastic plate can drive the cleaning scraper 52 to lift upward. At this time, the cleaning scraper 52 shrinks, and then the plastic plate is moved to between the two cleaning scrapers 52 on the support frame 51 under the drive of the side plate 310. At this time, when the hot cutting frame 16 cuts another group of plastic plates on the processing plate 12, the hot cutting frame 16 drives the supporting frame 42 to move, and the supporting frame 42 drives the supporting frame 51 to make the two cleaning scrapers 52 clean and scrape the processed part of the plastic plate, thereby scraping off the residual impurities on the cut part of the plastic plate and cleaning the surface of the plastic plate after cutting.

[0043] In this embodiment, Figure 1 , Figure 2 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 As shown, the processing plate 12 is also provided with a pushing mechanism 6, and the pushing mechanism 6 includes a one-way shaft 61 rotatably arranged on the top of the processing plate 12, and the one-way shaft 61 is provided with a first rotating gear 62 and a second rotating gear 63, and the top of the processing plate 12 is also slidably provided with a pushing tooth plate 64, and a side push frame 65 is fixedly connected to the pushing tooth plate 64, and the pushing tooth plate 64 is meshed with the second rotating gear 63, and a tension spring 66 is also connected between the pushing tooth plate 64 and the processing plate 12, and a positioning tooth plate 67 is also fixedly provided on the carrier frame 42, and the positioning tooth plate 67 is meshed with the first rotating gear 62;

[0044] After the hot cutting frame 16 cuts another set of plastic plates on the processing plate 12, the hot cutting frame 16 will be reset under the drive of the electric slide 15. When the hot cutting frame 16 is reset, it drives the carrier frame 42 to move and reset. The carrier frame 42 will drive the lower pressing frame 46 to move up and reset. At the same time, the carrier frame 42 moves, and the positioning tooth plate 67 on the carrier frame 42 contacts the first rotating gear 62. The positioning tooth plate 67 drives the first rotating gear 62 to rotate. When the first rotating gear 62 rotates, it drives the one-way shaft 61 to rotate, which will cause the second rotating gear 63 to rotate. The rotation of the second rotating gear 63 will drive the pushing tooth plate 64 to move. After the pushing tooth plate 64 moves, it will drive the side push frame 65 to The cleaned plastic sheet is pushed out to the transverse groove 13, so that the next group of plastic sheets can enter the two cleaning scrapers 52 when it moves to the transverse groove 13. When the hot cutting frame 16 and the hot cutting machine 17 cut the plastic sheet again, the support frame 42 moves, and the support frame 42 moves to drive the cleaning member 5 to clean the plastic sheet. Due to the one-way shaft 61, the second rotating gear 63 will not drive the tooth plate 64 to move, and the side push frame 65 will not push the plastic sheet being cleaned. At the same time, the tooth plate 64 is pushed to move and reset under the drive of the tension spring 66, so that the cleaned plastic sheet can be pushed and fed in the future to complete the cutting process of the plastic sheet.

[0045] The use method and advantages of the present invention: The use method of the plastic sheet heat cutting machine, the working process is as follows:

[0046] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 As shown:

[0047] S1: Place the plastic plate on top of the processing plate 12, and the hot cutting frame 16 moves along the plastic plate under the drive of the electric slide 15. The laser cutting operation is performed along the center line of the plastic plate under the drive of the hot cutting machine 17. After the plastic plate is cut, the pushing plate 21 drives the plate to move toward the direction of the transverse groove 13 under the drive of the pushing electric cylinder 14. When the pushing plate 21 continues to move the plate, the moving frame 22 at the bottom of the pushing plate 21 will move synchronously. When the moving frame 22 moves, the gap in the upper limit block 29 of the pushing plate 23 is pushed. The opening 210 abuts against the stopper 212 on the limit frame 27, and then when the moving frame 22 continues to move, the push plate 23 is limited by the limit frame 27 so that the push plate 23 cannot move. At the same time, the pressure spring 25 located between the moving frame 22 and the push plate 23 gradually accumulates force. When the push plate 21 moves the cut plastic plate to the transverse groove 13 on the processing plate 12, the wedge-shaped block 213 on the moving frame 22 will contact the inclined part of the limit frame 27. At this time, the wedge-shaped block 213 squeezes the limit frame 27 so that the limit frame 27 The support rod 26 is lifted upward. When the limit frame 27 is lifted, the stopper 212 on the limit frame 27 will separate from the notch 210 on the limit block 29. At this time, the pressure spring 25 after storing force will quickly push the propulsion plate 23. When the propulsion plate 23 moves, the propulsion plate 23 will drive the sliding plate 31 to move. The movement of the sliding plate 31 enables the rack 32 to drive the rotating gear 34 to rotate. The rotation of the rotating gear 34 drives the rotating rod 33 to rotate. The rotating frame 35 on the rotating rod 33 will expand outward in the accommodating chamber 11. , and the slide groove 36 provided on the rotating frame 35 will drive the clamping wheel 39 to move, so that the clamping rod 38 on the clamping wheel 39 can drive the two unfolding plates 37 that are close to each other to separate. When the pushing plate 21 pushes the cut plastic plate toward the direction of the horizontal groove 13, the plastic plate is cut along the center line, and the plastic plate is clamped between the two side plates 310 that are close to each other. When the two unfolding plates 37 are separated under the drive of the rotating frame 35, the two side plates 310 push the cut plastic plate in opposite directions.

[0048] S2: When the electric cylinder 14 drives the push plate 21 to move and reset, the push plate 21 resets and drives the moving frame 22 to move. When the moving frame 22 moves, it will synchronously drive the push plate 23 to move under the connection of the pressure spring 25. The push plate 23 will pull the sliding plate 31 to make the two unfolding plates 37 move and reset to a close state. When the push plate 23 moves, the inclined surface 211 of the upper limit block 29 of the push plate 23 will contact the stopper 212 on the limit frame 27. The stopper 212 on the limit frame 27 will not limit the stopper 29, so that the push plate 23 is driven by the moving frame 22 to move and reset. After the push plate 23 moves and resets, the notch 210 on the limit block 29 set will re-contact the stopper 212 on the limit frame 27, so that when the next plastic plate is pushed by the push plate 21, the cut plastic plate can be continuously separated.

[0049] S3: When the plastic plate is placed on the processing plate 12, the electric slide 15 drives the hot cutting frame 16 to move along the plastic plate, and the hot cutting frame 16 drives the hot cutting machine 17 to cut the plastic plate. When the hot cutting frame 16 moves, the hot cutting frame 16 drives the carrier frame 42 to move. The carrier frame 42 moves through the fixed rod 43 on the carrier frame 42 and contacts with the inclined groove 45 on the adjustment frame 44. At this time, the adjustment frame 44 is pressed down under the restriction of the inclined groove 45 and the fixed rod 43. After the adjustment frame 44 is pressed down, the lower pressing frame 46 is pressed down to press and limit the plastic plate, so that the separated plastic plate can be stably cleaned under the restriction of the lower pressing frame 46.

[0050] S4: After cutting, the plastic sheet is expanded outward through the expansion mechanism 3, and the plastic sheet moves toward the cleaning member 5. The outer wall of the plastic sheet squeezes the telescopic cleaning scraper 52. The bottom of the cleaning scraper 52 is inclined so that the plastic sheet can drive the cleaning scraper 52 to lift upward. At this time, the cleaning scraper 52 shrinks, and then the plastic sheet is moved between the two cleaning scrapers 52 on the support frame 51 under the drive of the side plate 310. At this time, when the hot cutting frame 16 cuts another group of plastic sheets on the processing plate 12, the hot cutting frame 16 drives the supporting frame 42 to move, and the supporting frame 42 drives the supporting frame 51 to make the two cleaning scrapers 52 clean and scrape the processed part of the plastic sheet;

[0051] S5: After the hot cutting frame 16 cuts another set of plastic plates on the processing plate 12, the hot cutting frame 16 is reset under the drive of the electric slide 15. When the hot cutting frame 16 is reset, it drives the carrier frame 42 to move and reset. The carrier frame 42 drives the lower pressing frame 46 to move upward and reset. At the same time, the carrier frame 42 moves, and the positioning tooth plate 67 on the carrier frame 42 contacts the first rotating gear 62. The positioning tooth plate 67 drives the first rotating gear 62 to rotate. When the first rotating gear 62 rotates, it drives the one-way shaft 61 to rotate, which causes the second rotating gear 63 to rotate. The second rotating gear 63 rotates. It will drive the tooth plate 64 to move, and after the tooth plate 64 moves, it will drive the side push frame 65 to push the cleaned plastic plate to the transverse groove 13, so that the next group of plastic plates can enter the two cleaning scrapers 52 when they move to the transverse groove 13. When the hot cutting frame 16 and the hot cutting machine 17 cut the plastic plate again, the support frame 42 moves, and the support frame 42 moves to drive the cleaning member 5 to clean the plastic plate. Due to the one-way shaft 61, the second rotating gear 63 will not drive the tooth plate 64 to move, and the side push frame 65 will not push the plastic plate being cleaned.

The laser cutting operation is performed along the center line of the plastic plate under the drive of the hot cutting machine (17). After the plastic plate is cut, the driving cylinder (14) drives the pushing plate (21) to move the plate toward the direction of the transverse groove (13). When the pushing plate (21) continues to move the plate, the moving frame (22) at the bottom of the pushing plate (21) moves synchronously. When the moving frame (22) moves, the notch (210) in the upper limit block (29) of the pushing plate (23) is pushed. ) abuts against the stopper (212) on the limit frame (27), and then when the moving frame (22) continues to move, the push plate (23) is limited by the limit frame (27) so that the push plate (23) cannot move. At the same time, the pressure spring (25) located between the moving frame (22) and the push plate (23) gradually accumulates force. When the push plate (21) moves the cut plastic plate to the transverse groove (13) on the processing plate (12), the wedge-shaped block (213) on the moving frame (22) contacts the inclined portion of the limit frame (27). At this time, the wedge-shaped block (213) squeezes the limit frame (27) so that the limit frame (27) ) is lifted upward on the support rod (26). When the limit frame (27) is lifted, the stopper (212) on the limit frame (27) is separated from the notch (210) on the limit block (29). At this time, the pressure spring (25) after accumulating force will quickly push the push plate (23). When the push plate (23) moves, the push plate (23) drives the sliding plate (31) to move. The movement of the sliding plate (31) enables the rack (32) to drive the rotating gear (34) to rotate. The rotation of the rotating gear (34) drives the rotating rod (33) to rotate. The rotating frame (35) on the rotating rod (33) is in the accommodating chamber ( 11), and the slide groove (36) provided on the rotating frame (35) drives the clamping wheel (39) to move, so that the clamping rod (38) on the clamping wheel (39) can drive the two mutually close unfolding plates (37) to separate, and when the push plate (21) pushes the cut plastic plate toward the direction of the transverse groove (13), the plastic plate is cut along the center line, and the plastic plate is clamped between the two mutually close side plates (310), and when the two unfolding plates (37) are separated under the drive of the rotating frame (35), the two side plates (310) push the cut plastic plate in opposite directions; S2: When the push cylinder (14) drives the push plate (21) to move and reset, the push plate (21) resets and drives the moving frame (22) to move. When the moving frame (22) moves, it will synchronously drive the push plate (23) to move under the connection of the pressure spring (25). The push plate (23) will pull the sliding plate (31) to move the two unfolding plates (37) to reset to a close state. When the push plate (23) moves, the inclined surface (211) of the upper limit block (29) of the push plate (23) will contact the limit frame (2 7), the stopper (212) on the limit frame (27) will not limit the stopper (29), so that the push plate (23) is moved and reset under the drive of the moving frame (22), and the notch (210) on the limiter (29) will re-contact the stopper (212) on the limit frame (27), so that when the next plastic plate is pushed by the push plate (21), the cut plastic plate can be continuously separated; S3: When the plastic plate is placed on the processing plate (12), the electric slide (15) drives the hot cutting frame (16) to move along the plastic plate, and the hot cutting frame (16) drives the hot cutting machine (17) to cut the plastic plate. When the hot cutting frame (16) moves, the hot cutting frame (16) drives the supporting frame (42) to move. The supporting frame (42) moves through the fixing rod (43) on the supporting frame (42) and contacts the inclined groove (45) on the adjusting frame (44). At this time, the adjusting frame (44) is pressed down under the restriction of the inclined groove (45) and the fixing rod (43). After the adjusting frame (44) is pressed down, the lower pressing frame (46) is pressed down to press and limit the plastic plate, so that the separated plastic plate can be stably cleaned under the restriction of the lower pressing frame (46). S4: After cutting, the plastic plate is expanded outward through the expansion mechanism (3), and the plastic plate moves toward the cleaning member (5). The outer wall of the plastic plate squeezes the telescopic cleaning scraper (52). The bottom of the cleaning scraper (52) is inclined so that the plastic plate can drive the cleaning scraper (52) to lift upward. At this time, the cleaning scraper (52) contracts, and then the plastic plate is moved between the two cleaning scrapers (52) on the support frame (51) under the drive of the side plate (310). At this time, when the hot cutting frame (16) cuts another group of plastic plates on the processing plate (12), the hot cutting frame (16) drives the supporting frame (42) to move, and the supporting frame (42) drives the supporting frame (51) to make the two cleaning scrapers (52) clean and scrape the processed part of the plastic plate; S5: After the hot cutting frame (16) cuts another set of plastic plates on the processing plate (12), the hot cutting frame (16) is reset under the drive of the electric slide (15). When the hot cutting frame (16) is reset, it drives the carrier frame (42) to move and reset. The carrier frame (42) drives the lower pressing frame (46) to move upward and reset. At the same time, the carrier frame (42) moves, and the positioning tooth plate (67) on the carrier frame (42) contacts the first rotating gear (62). The positioning tooth plate (67) drives the first rotating gear (62) to rotate. When the first rotating gear (62) rotates, it drives the one-way shaft (61) to rotate, which causes the second rotating gear (63) to rotate. The second rotating gear (63) ) rotates, which drives the push tooth plate (64) to move. After the push tooth plate (64) moves, it drives the side push frame (65) to push the cleaned plastic plate to the transverse groove (13), so that the next group of plastic plates can enter the two cleaning scrapers (52) when they move to the transverse groove (13). When the hot cutting frame (16) cuts the plastic plate again with the hot cutting machine (17), the support frame (42) moves, and the support frame (42) moves to drive the cleaning member (5) to clean the plastic plate.
