[0010] Preferably, the processing plate is also provided with a pushing mechanism, and the pushing mechanism includes a one-way shaft rotatably arranged on the top of the processing plate, and a first rotating gear and a second rotating gear are arranged on the one-way shaft. A pushing tooth plate is also slidably arranged on the top of the processing plate, and a side pushing frame is fixedly connected to the pushing tooth plate, and the pushing tooth plate is meshed with the second rotating gear. A tension spring is also connected between the pushing tooth plate and the processing plate, and a positioning tooth plate is also fixedly arranged on the supporting frame, and the positioning tooth plate is meshed with the first rotating gear.

[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 sliding table drives the hot cutting frame to move along the plastic plate. The hot cutting frame drives the hot cutting machine to perform a cutting operation on the plastic plate. When the hot cutting frame moves, the hot cutting frame will drive the bearing frame to move. When the bearing frame moves, the fixed rod on the bearing frame will contact the inclined slot on the adjusting frame. At this time, under the restriction of the inclined slot and the fixed rod, the adjusting frame will be pressed down. After the adjusting frame is pressed down, the pressing frame will be pressed down to press and limit the plastic plate, so that the separated plastic plate can be stably subjected to subsequent cleaning operations under the limitation of the pressing frame;

[0015] S4: After cutting, the plastic plate is unfolded outward by the expansion mechanism, and the plastic plate will move towards the cleaning part. The outer wall of the plastic plate squeezes the telescopically arranged cleaning scraper. The bottom of the cleaning scraper is inclined so that the plastic plate can drive the cleaning scraper to lift upward. At this time, the cleaning scraper shrinks. Subsequently, under the drive of the side plate, the plastic plate is moved between the two cleaning scrapers on the support frame. At this time, when the hot cutting frame cuts another group of plastic plates on the processing plate, the hot cutting frame drives the bearing frame to move, and the bearing frame will drive the support frame to clean and sweep the processing part of the plastic plate with the two cleaning scrapers;

[0016] S5: After the hot cutting frame cuts another group of plastic plates on the processing plate, under the drive of the electric sliding table, the hot cutting frame will be reset. When the hot cutting frame is reset, it drives the bearing frame to move back to its original position. The bearing frame will drive the pressing frame to move upward and reset. At the same time, when the bearing frame moves, the positioning tooth plate on the bearing frame contacts the first rotating gear, and the positioning tooth plate will drive the first rotating gear to rotate. When the first rotating gear rotates, it drives the one-way shaft to rotate, which will cause the second rotating gear to rotate. When the second rotating gear rotates, it 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 cross groove, so that when the next group of plastic plates move to the cross groove, they can enter between the two cleaning scrapers. When the hot cutting frame cuts the plastic plate with the hot cutting machine again, when the bearing frame moves, the bearing frame drives the cleaning part to clean the plastic plate. Due to the one-way shaft provided, the second rotating gear will not drive the pushing tooth plate to move, and thus will not cause the side pushing frame to push the plastic plate being cleaned.

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

[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.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the present invention.

[0034] See also Figures 1 to 10, the present invention provides a technical solution: a plastic sheet hot cutting machine, including a processing table 1 arranged horizontally. On the top of the processing table 1, there is a processing plate 12 for placing plastic sheets. On the top of the processing table 1, a pushing electric cylinder 14 is fixedly arranged. The telescopic end of the pushing electric cylinder 14 is connected to a propulsion mechanism 2. The propulsion mechanism 2 is slidably matched with the processing plate 12.

The expansion mechanism 3 is connected to the propulsion mechanism 2. A transverse groove 13 is opened at the position of the processing plate 12 corresponding to the expansion mechanism 3. On the top of the processing table 1, an electric sliding table 15 is also arranged. On the electric sliding table 15, there is a hot cutting frame 16. A hot cutting machine 17 is fixedly arranged on the hot cutting frame 16. The hot cutting machine 17 is arranged towards the processing plate 12. On both sides of the transverse groove 13 at the top of the processing plate 12, a limiting mechanism 4 is arranged.

[0035] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 shown, the propulsion mechanism 2 includes a pushing plate 21 fixedly connected to the telescopic end of the pushing electric cylinder 14. The pushing plate 21 is slidably matched with the processing table 1. At the bottom of the pushing plate 21, a moving frame 22 is fixedly connected. The moving frame 22 is slidably matched with the accommodation cavity 11 on the processing table 1. A propulsion plate 23 is slidably arranged on the moving frame 22. A limiting rod 24 is fixedly connected to the propulsion plate 23. The limiting rod 24 is slidably matched with the moving frame 22. A pressure spring 25 is sleeved on the limiting rod 24. The two ends of the pressure spring 25 are respectively connected to the propulsion plate 23 and the moving frame 22. A support rod 26 is fixedly connected in the accommodation cavity 11 of the processing table 1. A limiting frame 27 is rotatably arranged on the support rod 26. A torsion spring 28 is sleeved on the support rod 26. The two ends of the torsion spring 28 are respectively connected to the support rod 26 and the limiting frame 27. A limiting block 29 is fixedly arranged on the propulsion plate 23. A notch 210 is opened on one side of the limiting block 29. An inclined surface 211 is arranged on the other side of the limiting block 29 away from the notch 210. The end of the limiting frame 27 facing the limiting block 29 is inclined. And a stop block 212 for abutting against the notch 210 on the limiting block 29 is arranged at the bottom of the limiting frame 27. A wedge-shaped block 213 is also fixedly arranged on the moving frame 22. The wedge-shaped block 213 contacts the inclined end of the limiting frame 27;

[0036] The expansion mechanism 3 includes a sliding plate 31 slidably disposed in the accommodation cavity 11. The sliding plate 31 is fixedly connected to the propulsion plate 23. Rack bars 32 are fixedly provided on both sides of the sliding plate 31. Rotating rods 33 are rotatably disposed on both sides of the sliding plate 31 in the accommodation cavity 11. A rotating gear 34 is fixedly connected to the rotating rod 33. The rotating gear 34 meshes with the rack bar 32 on the sliding plate 31. A rotating frame 35 is also fixedly connected to the rotating rod 33. A sliding groove 36 is formed in the rotating frame 35. An unfolding plate 37 is slidably disposed on the processing plate 12. A clamping rod 38 is fixedly connected to the unfolding plate 37. A clamping wheel 39 is rotatably disposed on the clamping rod 38. The clamping wheel 39 is located in the sliding groove 36. A side plate 310 extending towards the transverse groove 13 is provided on the unfolding plate 37. The side plate 310 is slidably engaged with the transverse groove 13;

[0037] Place the plastic plate on the top of the processing plate 12. The hot cutting machine frame 16 moves along the plastic plate driven by the electric sliding table 15 and performs laser cutting operations along the center line of the plastic plate driven by the hot cutting machine 17. After the plastic plate is cut, the pushing plate 21 will drive the plate to move towards the direction of the transverse groove 13 driven by the pushing electric cylinder 14. When the pushing plate 21 continuously moves 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 limit block 29 on the pushing plate 23 abuts against the stop block 212 on the limit frame 27. Then, when the moving frame 22 continuously moves, the pushing plate 23 is limited by the limit frame 27 so that the pushing plate 23 cannot move and the compression spring 25 located between the moving frame 22 and the pushing plate 23 gradually stores energy. 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 on the limit frame 27. At this time, the wedge-shaped block 213 squeezes the limit frame 27 to make the limit frame 27 lift upward on the support rod 26. After the limit frame 27 lifts, the stop block 212 on the limit frame 27 will separate from the notch 210 on the limit block 29. At this time, the compressed compression spring 25 will quickly push the pushing plate 23. When the pushing plate 23 moves, the pushing 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 cavity 11. The chute 36 opened on the rotating frame 35 will drive the clamping wheel 39 to move. Thus, the clamping rod 38 on the clamping wheel 39 can drive the two approaching expansion plates 37 to separate. When the pushing plate 21 pushes the cut plastic plate towards the direction of the transverse groove 13, since the plastic plate is cut along its center line, the plastic plate will be stuck between the two approaching side plates 310. When the two expansion plates 37 are separated driven by 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, there are residues on the surface of its outer wall. When the cut plastic plates are separated, they can be further processed through the limiting mechanism 4 on both sides of the transverse groove 13, and the two cut plates are processed respectively, improving the processing efficiency of the plastic plates;

[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 Figure 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 , Figure 9 and Figure 10 As shown in Figure 8 , Figure 9 , and Figure 10 , a cleaning member 5 is further provided on the carrier 42. The cleaning member 5 includes a support frame 51 fixedly connected to the outer wall of the carrier 42. At the bottom of both sides of the support frame 51, cleaning scrapers 52 are provided. A friction layer is provided on the inner wall of the cleaning scraper 52. Both cleaning scrapers 52 are elastically telescopic.

[0042] After cutting, the plastic sheet is unfolded outward by the expanding mechanism 3, and the plastic sheet will move in the direction of the cleaning member 5. The outer wall of the plastic sheet presses against the elastically 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 contracts, and then under the drive of the side plate 310, the plastic sheet is moved to between the two cleaning scrapers 52 on the support frame 51. 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 carrier 42 to move, and the carrier 42 will drive the support frame 51 to make the two cleaning scrapers 52 clean and sweep the processing area of the plastic sheet, so as to scrape off the residual impurities on the cutting part of the plastic sheet and clean the surface of the cut plastic sheet.

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

[0047] S1: Place the plastic board on the top of the processing board 12. The hot cutting machine frame 16 moves along the plastic board driven by the electric slide table 15, and performs laser cutting operations along the midline of the plastic board driven by the hot cutting machine 17. After the plastic board is cut, the pushing plate 21 will drive the board to move towards the transverse groove 13 driven by the pushing electric cylinder 14. When the pushing plate 21 continuously moves the board, 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 limit block 29 on the pushing plate 23 abuts against the stop block 212 on the limit frame 27. Then, when the moving frame 22 continues to move, the pushing plate 23 is limited by the limit frame 27 so that the pushing plate 23 cannot move, and the compression spring 25 located between the moving frame 22 and the pushing plate 23 gradually stores energy. When the pushing plate 21 moves the cut plastic board to the transverse groove 13 on the processing board 12, the wedge-shaped block 213 on the moving frame 22 will contact the inclined part on the limit frame 27. At this time, the wedge-shaped block 213 squeezes the limit frame 27 to lift the limit frame 27 upward on the support rod 26. After the limit frame 27 is lifted, the stop block 212 on the limit frame 27 will separate from the notch 210 on the limit block 29. At this time, the compressed spring 25 that has stored energy will quickly push the pushing plate 23. When the pushing plate 23 moves, the pushing 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 cavity 11. The sliding groove 36 opened on the rotating frame 35 will drive the clamping wheel 39 to move. Furthermore, the clamping rod 38 on the clamping wheel 39 can drive the two approaching expansion plates 37 to separate. When the pushing plate 21 pushes the cut plastic board towards the transverse groove 13, because the plastic board is cut along its midline, the plastic board will be stuck between the two approaching side plates 310. When the two expansion plates 37 are separated driven by the rotating frame 35, the two side plates 310 will push the cut plastic board in opposite directions;

[0048] S2: When the push cylinder 14 drives the push plate 21 to move back to its original position, the push plate 21 drives the moving frame 22 to move when it returns to its original position. When the moving frame 22 moves, it will synchronously drive the propulsion plate 23 to move under the connection of the compression spring 25. The propulsion plate 23 will then pull the sliding plate 31 to move the two expansion plates 37 back to their original position and close state. When the propulsion plate 23 moves, the inclined surface 211 of the limit block 29 on the propulsion plate 23 will contact the stop block 212 on the limit frame 27. The stop block 212 on the limit frame 27 will not limit or block the limit block 29. Thus, the propulsion plate 23 moves back to its original position driven by the moving frame 22. After the propulsion plate 23 moves back to its original position, the notch 210 on the limit block 29 provided will re-contact the stop block 212 on the limit frame 27. Thus, when the next plastic plate is pushed by the push plate 21, the cut plastic plates can be continuously separated;

[0049] S3: When the plastic plate is placed on the processing plate 12, the electric slide table 15 drives the hot cutting frame 16 to move along the plastic plate. The hot cutting frame 16 drives the hot cutting machine 17 to perform cutting operations on the plastic plate. When the hot cutting frame 16 moves, the hot cutting frame 16 will drive the bearing frame 42 to move. The bearing frame 42 moves and the fixed rod 43 on the bearing frame 42 will contact the inclined slot 45 on the adjusting frame 44. At this time, under the restriction of the inclined slot 45 and the fixed rod 43, the adjusting frame 44 will be pressed down. After the adjusting frame 44 is pressed down, the pressing frame 46 will be pressed down to press and limit the plastic plate, so that the separated plastic plate can be stably subjected to subsequent cleaning operations under the limitation of the pressing frame 46;

[0050] S4: The cut plastic plate unfolds outward through the expansion mechanism 3, and the plastic plate will move towards the cleaning member 5. The outer wall of the plastic plate squeezes the telescopically arranged cleaning squeegee 52. The bottom of the cleaning squeegee 52 is inclined so that the plastic plate can drive the cleaning squeegee 52 to lift upward. At this time, the cleaning squeegee 52 contracts. Subsequently, driven by the side plate 310, the plastic plate moves to between the two cleaning squeegees 52 on the support frame 51. 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 bearing frame 42 to move. The bearing frame 42 will drive the support frame 51 to make the two cleaning squeegees 52 clean and sweep the processing area of the plastic plate;

[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.

5. The method for using a plastic sheet heat cutting machine according to claim 4, characterized in that: The steps include: S1: Place the plastic plate on top of the processing plate (12). The hot cutting machine frame (16) moves along the plastic plate driven by the electric sliding table (15), and performs laser cutting operations along the center line of the plastic plate driven by the hot cutting machine (17). After the plastic plate is cut, the pushing plate (21) drives the plate to move towards the transverse groove (13) driven by the pushing electric cylinder (14). When the pushing plate (21) continuously moves 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 limit block (29) on the pushing plate (23) abuts against the stop block (212) on the limit frame (27). Then, when the moving frame (22) continues to move, the pushing plate (23) is limited by the limit frame (27) so that the pushing plate (23) cannot move, and the compression spring (25) between the moving frame (22) and the pushing plate (23) gradually stores energy. 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 on the limit frame (27). At this time, the wedge-shaped block (213) squeezes the limit frame (27) to lift the limit frame (27) upward on the support rod (26). After the limit frame (27) is lifted, the stop block (212) on the limit frame (27) will separate from the notch (210) on the limit block (29). At this time, the compressed spring (25) that has stored energy will quickly push the pushing plate (23). When the pushing plate (23) moves, the pushing 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 cavity (11). The sliding groove (36) opened on the rotating frame (35) will drive the caster wheel (39) to move, so that the clamping rod (38) on the caster wheel (39) can drive the two approaching expansion plates (37) to separate. When the pushing plate (21) pushes the cut plastic plate towards the transverse groove (13), because the plastic plate is cut along its center line, the plastic plate will be stuck between the two approaching side plates (310). When the two expansion plates (37) are driven by the rotating frame (35) to separate, the two side plates (310) will push the cut plastic plate in opposite directions; S2: When the push cylinder (14) drives the push plate (21) to move back to its original position, the push plate (21) drives the moving frame (22) to move when it returns to its original position. When the moving frame (22) moves, it will synchronously drive the push plate (23) to move under the connection of the compression spring (25). The push plate (23) will pull the sliding plate (31) to move the two expansion plates (37) back to their closed state. When the push plate (23) moves, the inclined surface (211) of the limit block (29) on the push plate (23) will contact the stop block (212) on the limit frame (27). The stop block (212) on the limit frame (27) will not limit or block the limit block (29), so that the push plate (23) moves back to its original position driven by the moving frame (22). After the push plate (23) moves back to its original position, the notch (210) on the set limit block (29) will abut against the stop block (212) on the limit frame (27) again, so that when the next plastic plate is pushed by the push plate (21), the cut plastic plates can be continuously separated; S3: When the plastic plate is placed on the processing plate (12), the electric slide table (15) drives the hot cutting frame (16) to move along the plastic plate. 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 carrier frame (42) to move. The carrier frame (42) moves and the fixed rod (43) on the carrier frame (42) will contact the inclined groove (45) on the adjusting frame (44). At this time, under the restriction of the inclined groove (45) and the fixed rod (43), the adjusting frame (44) will be pressed down. After the adjusting frame (44) is pressed down, the pressing frame (46) will be pressed down to press and limit the plastic plate, so that the separated plastic plate can be stably subjected to subsequent cleaning operations under the limit of the pressing frame (46); S4: After being cut, the plastic plate is unfolded outward by the expansion mechanism (3), and the plastic plate will move in the direction of the cleaning part (5). The outer wall of the plastic plate presses the telescopically arranged 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. Then, driven by the side plate (310), the plastic plate moves between the two cleaning scrapers (52) on the support frame (51). 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 carrier frame (42) to move, and the carrier frame (42) will drive the support frame (51) to make the two cleaning scrapers (52) clean and sweep the processing 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. Due to the one-way shaft (61), the second rotating gear (63) will not drive the push tooth plate (64) to move, and the side push frame (65) will not push the plastic plate being cleaned.
