[0003] At present, veneer panel manufacturers all use scraper machines to scrape the four sides of the hot-pressed panels. Among them, scraper mechanisms such as scrapers are set on both sides of the conveying mechanism for conveying the veneer panels. During the conveying process, when the veneer panels pass through the scraper mechanisms, the scraper mechanisms scrape the two sides of the veneer panels, and then scrape the other two sides of the veneer panels.

[0044] The present invention provides an automatic paper scraping production line for decorative panels. In order to make the purpose, technical solution and effect of the present invention clearer and more specific, the present invention is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention and are not used to limit the present invention.

[0045] It should be noted here that when describing the orientation of the first conveying mechanism, the conveying direction of the first conveying mechanism is the front-to-back direction; when describing the orientation of the second conveying mechanism, the conveying direction of the second conveying mechanism is the front-to-back direction; when describing the orientation of the lifting mechanism and the support member, the conveying direction of the first conveying mechanism is the front-to-back direction.

[0046] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 The present invention provides an automatic paper scraping production line for decorative panels, which includes a first conveying mechanism 100 and a second conveying mechanism 200 for conveying decorative panels 500, a plate lifting mechanism 102 respectively arranged on both sides of the first conveying mechanism 100, a paper scraping mechanism 104 respectively arranged on both sides of the first conveying mechanism 100, a plate lifting mechanism 202 respectively arranged on both sides of the second conveying mechanism 200, a paper scraping mechanism 204 respectively arranged on both sides of the second conveying mechanism 200, a positioning mechanism 103 respectively arranged on both sides of the first conveying mechanism 100 and capable of moving toward the middle to center the lifted decorative panel 500, a positioning mechanism 203 respectively arranged on both sides of the second conveying mechanism 200 and capable of moving toward the middle to center the lifted decorative panel 500, a lifting mechanism 400 arranged on the exit side of the first conveying mechanism 100 and located in front of the plate lifting mechanism 202 of the second conveying mechanism 200, a control device (not shown in the figure), and a position detector (not shown in the figure).

[0047] The second conveying mechanism 200 is disposed at the outlet end of the first conveying mechanism 100 and its conveying direction is perpendicular to the conveying direction of the first conveying mechanism 100 ; and the conveying plane of the second conveying mechanism 200 is lower than the conveying plane of the first conveying mechanism 100 .

[0048] like Figure 2 , Figure 3 , Figure 4 As shown, in the structure of the first conveying mechanism 100, the positioning mechanism 103 is located at both ends of the plate lifting mechanism 102, that is, at the front and rear ends of the plate lifting mechanism 102; the positioning mechanism 103 can move back and forth along the horizontal direction perpendicular to the conveying direction of the first conveying mechanism 100; the scraping mechanism 104 is located behind the plate lifting mechanism 102. In the structure of the second conveying mechanism 200, the positioning mechanism 203 is located at both ends of the plate lifting mechanism 202, that is, at the front and rear ends of the plate lifting mechanism 202; the positioning mechanism 203 can move back and forth along the horizontal direction perpendicular to the conveying direction of the second conveying mechanism 200; the scraping mechanism 204 is located behind the plate lifting mechanism 202.

[0049] like Figure 1 , Figure 4 , Figure 5 , Figure 6 As shown, a plurality of support members 405 with a circular axial cross-section for supporting the decorative panel 500 can be rotatably provided on the top of the lifting mechanism 400; the axial direction of the support member 405 is consistent with the conveying direction of the second conveying mechanism 200; the top surface of the support member 405 is flush with the conveying plane of the first conveying mechanism 100 when the lifting mechanism 400 rises into position, and is used to support the decorative panel conveyed from the first conveying mechanism 100, and is located below the conveying plane of the second conveying mechanism 200 when the lifting mechanism 400 descends into position; from a top-down perspective, the projection surface of the support member 405 crosses and overlaps with the conveying plane of the second conveying mechanism 200, so that the support member 405 places the supported decorative panel on the conveying plane of the second conveying mechanism 200 through a downward movement.

[0050] The position detectors are respectively arranged at the rear side of the plate lifting mechanism 102 of the first conveying mechanism 100, the rear side of the plate lifting mechanism 202 of the second conveying mechanism 200, and the left rear side of the lifting mechanism 400. The position detectors can be, but are not limited to, non-contact position detectors such as photoelectric proximity switches. The non-contact position detectors are used to prevent them from causing damage to the surface of the decorative panel.

[0051] The control device is electrically connected to the position detector, the first conveying mechanism, the second conveying mechanism, the paper scraping mechanism, the plate lifting mechanism, the positioning mechanism and the lifting mechanism. The control device can be, but is not limited to, a PLC controller.

[0052] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, when the veneer panel 500 moves on the first conveying mechanism 100, the position detector detects that it moves to the plate lifting mechanism 102, and the control device controls the plate lifting mechanism 102 to rise and lift the veneer panel according to the signal of the position detector, and then controls the positioning mechanism 103 to move closer to the veneer panel to center the veneer panel. After the centering is completed, the plate lifting mechanism 102 moves down, allowing the first conveying mechanism 100 to continue conveying, and the paper scraping (or edge scraping) process is completed through the paper scraping mechanism 104.

[0053] Subsequently, the decorative panel moves from the first conveying mechanism 100 to the support 405 on the lifting mechanism 400. When the position detector located on the left rear side of the lifting mechanism 400 detects that the decorative panel has moved into place, the control device controls the lifting mechanism 400 to descend according to the signal of the position detector until the decorative panel falls onto the conveying plane of the second conveying mechanism 200, and the decorative panel is transported by the second conveying mechanism 200.

[0054] When the position detector located at the left rear side of the lifting mechanism 400 detects that the decorative panel has completely left the area directly above the lifting mechanism under the conveying action of the second conveying mechanism 200, the control device controls the lifting mechanism 400 to move up and return to the original position to wait for the next decorative panel conveyed from the first conveying mechanism. The lifting mechanism and the support are set to complete the 90° transfer of the decorative panel, from the first conveying mechanism to the second conveying mechanism, so that the scraping mechanism 204 can scrape the remaining two sides of the decorative panel.

[0055] Similarly, the position detector located at the rear side of the plate lifting mechanism 202 detects that the veneer panel has moved into position under the conveying action of the second conveying mechanism 200, and then the control device controls the plate lifting mechanism 202 to move up, lift the veneer panel, and then the positioning mechanism 203 starts to work under the control of the control device, moving closer to the two sides of the veneer panel to achieve the centering of the veneer panel. After the centering is completed, the plate lifting mechanism 202 descends, allowing the second conveying mechanism 200 to continue to convey the veneer panel, and then the scraping mechanism 204 located on both sides of the second conveying mechanism 200 performs the scraping work.

[0056] During the conveying process of the first conveying mechanism and the second conveying mechanism, the scrapers of the scraping mechanism 104 and the scraping mechanism 204 contact the two side surfaces of the veneer panel to scrape off the excess surface paper (or veneer material) protruding from the side surfaces of the veneer panel.

[0057] like Figure 1 , Figure 4As shown, a conveying mechanism 300 can be set at the outlet end of the second conveying mechanism 200. A third brush 301 is provided above the conveying mechanism 300 to remove the scraps of paper on the top surface of the decorative panel that has been scraped off. The staff does not need to handle it by themselves, thus reducing manpower investment.

[0058] like Figure 1 , Figure 2 , Figure 4 , Figure 5 As shown, the structures of the first conveying mechanism 100 and the second conveying mechanism 200 are consistent. The first conveying mechanism 100 includes a frame 107 and at least two belt conveying components 101 spaced apart and arranged in parallel. The second conveying mechanism 200 includes a frame 207 and at least two belt conveying components 201 spaced apart and arranged in parallel. In this embodiment, the first conveying mechanism 100 is evenly spaced apart and three belt conveying components 101 are evenly spaced apart, and the second conveying mechanism 200 is evenly spaced apart and four belt conveying components 201 are evenly spaced apart.

[0059] Specifically, Figure 7 As shown, the belt conveying component includes a supporting square rod 12 horizontally fixed on the frame 7, a driving roller 14 and a driven roller 13 rotatably arranged at both ends of the supporting square rod 12, a conveying belt 11 wound between the driving roller 14 and the driven roller 13, and a first driving mechanism for driving the driving roller 14 to rotate. The driving roller 14 and the driven roller 13 are provided with a rotating shaft, which is installed on a bearing seat fixed to the supporting square rod 12, so that the driving roller and the driven roller can rotate relative to the supporting square rod, and then the conveying belt 11 is driven by the first driving mechanism to work.

[0060] More specifically, the first driving mechanism is a driving motor 15 fixed to the frame 7; the driving motor 15 is connected to a transmission shaft 16, and the transmission shaft 16 is coaxially connected to all the active rollers 13. The output shaft of the driving motor 15 is provided with a driving pulley 18, and one end of the transmission shaft 16 is provided with a transmission pulley 17, and a transmission belt (not shown in the figure) is wound between the driving pulley 18 and the transmission pulley 17. When the driving motor 15 works, the transmission shaft 16 is driven to rotate by the transmission belt, thereby driving the conveyor belt 11 to convey the veneer panel. The driving motor 15 is electrically connected to the control device.

[0061] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the plate lifting mechanisms 102 are respectively arranged on the outside of the belt conveying components 101 , and the plate lifting mechanisms 202 are respectively arranged on the outside of the belt conveying components 201 .

[0062] Of course, a roller conveyor may be used to replace the belt conveyor component, and the plate lifting mechanism 102 and the plate lifting mechanism 202 may be arranged between the rollers.

[0063] like Figure 1 , Figure 2 , Figure 4 , Fig.10 As shown, a scraper mechanism 104 is provided on both sides of the first conveying mechanism 100, and a scraper mechanism 204 is provided on both sides of the second conveying mechanism 200. The scraper mechanism 4 is slidably connected to a fixed guide rail 41, and the scraper mechanism 4 is connected to a first telescopic cylinder 42 that can drive the scraper mechanism 4 to move from both sides of the first conveying mechanism 100 and both sides of the second conveying mechanism 200 to the middle. The first telescopic cylinder 42 is electrically connected to the control device.

[0064] Specifically, Fig.10 As shown, a connector 45 fixedly connected to the piston rod of the first telescopic cylinder 42 is fixedly provided at the bottom of the scraper mechanism 4, and the first telescopic cylinder 42 is fixed to a U-shaped bracket 43, and the bracket 43 can be fixed to the frame of the first conveying mechanism 100 and the second conveying mechanism 200. In addition, a second brush 44 for cleaning the side of the decorative panel is fixed to the rear side of the scraper mechanism 4, which is used to remove the scraps of paper on the two sides of the decorative panel.

[0065] The piston rod of the first telescopic cylinder 42 is extended and retracted to drive the scraper mechanism 4 to move back and forth along the length direction of the guide rail 41, so that the staff can adjust the distance between the scraper mechanisms, thereby enabling the automatic scraper assembly line to scrape the sides of decorative panels of different sizes.

[0066] like Figure 2 , Figure 3 , Figure 4 As shown, the first conveying mechanism 100 is provided with two sets of positioning mechanisms 103, and the second conveying mechanism 200 is provided with two sets of positioning mechanisms 203. Fig. 9 As shown, the positioning mechanism includes a vertical rod 35, a positioning roller 31 coaxially arranged on the top of the vertical rod 35, and a second driving mechanism for driving the positioning roller 31 to move to abut against the side of the decorative panel.

[0067] In this embodiment, two positioning rollers 31 are arranged on both sides of the first conveying mechanism 100 and the second conveying mechanism 200, which are rotatably arranged on the top of the vertical rod 35 through bearings, to center the decorative panel. When the plate lifting mechanism lifts the decorative panel, the positioning roller 31 moves toward the middle of the first conveying mechanism 100 or the second conveying mechanism 200 under the operation of the second driving mechanism, pushing the decorative panel to achieve centering and positioning. Then, the plate lifting mechanism moves down with the decorative panel, and the rolling surface of the positioning roller 31 is always in contact with the side of the decorative panel to avoid the decorative panel from shifting during the downward movement, resulting in poor positioning effect. After moving down to the right position, the first conveying mechanism 100 or the second conveying mechanism 200 continues to convey the decorative panel. When the decorative panel moves along the conveying direction, the positioning roller 31 rotates relative to the decorative panel, reducing the contact area between the positioning roller and the decorative panel, thereby reducing friction, so as to achieve both better positioning effect and fast and stable conveying of the decorative panel, thereby improving work efficiency.

[0068] Specifically, the second driving mechanism is a fixed second telescopic cylinder 32, a first slide seat 33 is fixed to the bottom of the vertical rod 35, and the first slide seat 33 is slidably connected to a fixed first slide rail 34; the piston rod of the second telescopic cylinder 32 is connected to the first slide seat 33. The second telescopic cylinder 32 and the first slide rail 34 are fixed to a support plate 36, and the support plate 36 is fixed to the frame of the first conveying mechanism 100 and the second conveying mechanism 200 by welding or bolts. The second telescopic cylinder 32 is electrically connected to the control device.

[0069] The piston rod of the second telescopic cylinder 32 is extended in a direction perpendicular to the conveying direction, and the first slide rail 34 and the second telescopic cylinder are both arranged horizontally. The fixed second telescopic cylinder 32 drives the first slide seat 33 to move back and forth relative to the first slide rail 34, thereby prompting the positioning rollers 31 located on both sides of the first conveying mechanism 100 and the second conveying mechanism 200 to move in a horizontal direction perpendicular to the conveying direction, so as to center and position the decorative panel.

[0070] Of course, in addition to using the second telescopic cylinder, a motor and a screw rod can also be used instead. The motor drives the screw rod to rotate, and the rotation of the screw rod drives the first slide 33 threadedly connected to it, driving the first slide 33 to move back and forth along the first slide rail 34.

[0071] like Figure 2 , Figure 3 , Figure 4 As shown, a plate lifting mechanism 102 is provided on both sides of the first conveying mechanism 100, and a plate lifting mechanism 202 is provided on both sides of the second conveying mechanism 200. Figure 8As shown, the plate lifting mechanism includes a lifting rod 22 which is horizontally arranged on both sides of the first conveying mechanism 100 and whose length direction is consistent with the conveying direction of the first conveying mechanism 100 or is horizontally arranged on both sides of the second conveying mechanism 200 and whose length direction is consistent with the conveying direction of the second conveying mechanism 200, a plurality of supporting rollers 21 which are spaced apart at the top of the lifting rod 22, and a third driving mechanism for driving the lifting rod 22 to move up and down; the axial direction of the supporting roller 21 is consistent with the length direction of the lifting rod 22.

[0072] The decorative panel is driven to move up and down by the lifting rod 22, and support rollers 21 are also provided to provide a supporting function; moreover, when the positioning mechanisms 103 and 203 are correspondingly moved toward the middle of the first conveying mechanism 100 and the second conveying mechanism 200 to center the decorative panel, the decorative panel moves in a horizontal direction perpendicular to the conveying direction due to the push of the positioning mechanism. In order to avoid damage to the surface of the decorative panel, a plurality of support rollers 21 are specially provided on the lifting rod 22. When the decorative panel moves, the contact area with the decorative panel is reduced, and the sliding friction is changed to rolling friction, which greatly reduces friction, makes the decorative panel move faster, speeds up the centering efficiency, and the surface of the decorative panel is well protected.

[0073] Specifically, the third driving mechanism is a third telescopic cylinder 26 that is fixedly arranged, a guide rod 24 is fixedly arranged at the bottom of the lifting rod 22, the guide rod 24 is slidably connected to a fixed guide seat 23, and a piston rod of the third telescopic cylinder 26 is connected to the lifting rod 22. The third telescopic cylinder 26 is electrically connected to the control device.

[0074] Of course, in addition to using the third telescopic cylinder, a motor and a screw rod can also be set up instead. The motor drives the screw rod to rotate. Correspondingly, a connecting part that is threadedly connected to the screw rod is provided at the bottom of the lifting rod. During the rotation of the screw rod, the lifting rod threadedly connected to it is driven to rise and fall.

[0075] In this embodiment, four supporting rollers 21 are evenly mounted on the top surface of the lifting rod 22 through roller brackets. In addition, positioning mechanisms are respectively arranged outside the two ends of the lifting rod 22. The frames of the first conveying mechanism 100 and the second conveying mechanism 200 are fixed with a U-shaped bracket 25 by welding or bolting, the cylinder body of the third telescopic cylinder 26 is bolted to the U-shaped bracket 25, and the guide seat 23 is also bolted to the U-shaped bracket 25. Moreover, the guide seat 23 is symmetrical about the piston rod of the third telescopic cylinder 26.

[0076] like Figure 1 , Figure 5 , Figure 6As shown, the support member 405 is a roller arranged between the belt conveying components 201 of the second conveying mechanism 200; the lifting mechanism 400 includes a lifting frame 401 slidably arranged on the frame 207 of the second conveying mechanism 200, and a fourth driving mechanism for driving the lifting frame 401 to move up and down; the roller is rotatably arranged on the lifting frame 401 through a bearing seat.

[0077] Specifically, the fourth driving mechanism is a fourth telescopic cylinder 402 fixed to the frame 207 of the second conveying mechanism 200; the fourth telescopic cylinder 402 is respectively arranged on both sides of the lifting frame 401 and the piston rod of the fourth telescopic cylinder 402 is fixedly connected to the lifting frame 401; the two sides of the lifting frame 401 are respectively provided with second slide rails 404, and the frame 207 of the second conveying mechanism 200 is correspondingly provided with a second slide seat 403 connected to the second slide rail 404 for sliding up and down. The cylinder body and the second slide seat 403 of the fourth telescopic cylinder 402 can be installed on the frame 207 of the second conveying mechanism 200 by bolts, and the fourth telescopic cylinder 402 works to drive the lifting frame 401 to move back and forth along the height direction. The fourth telescopic cylinder 402 is electrically connected to the control device.

[0078] In this embodiment, two fourth telescopic cylinders 402 are respectively provided on both sides of the lifting frame 401. The four fourth telescopic cylinders 402 work simultaneously, and in addition, a second slide rail 404 and a second slide seat 403 are provided to realize the rapid and stable rise or fall of the lifting frame 401, and ensure that the top surfaces of all the support members 405 on the lifting frame are in a horizontal plane, thereby ensuring that the decorative panel moves from the horizontal conveying plane of the first conveying mechanism to the horizontal top surface of the support member without tilting and sliding.

[0079] Certainly, a driving device can be set to drive the support member to rotate, such as a motor drives the support frame to rotate by driving a chain. In addition, when using a roller conveyor to replace the belt conveyor component, a plurality of rollers arranged between adjacent rollers can be used to make the support member.

[0080] Furthermore, if Figure 2 , Figure 3 , Figure 4 As shown, a belt conveyor 105 and a shredded paper recovery box (not shown in the figure) located at the outlet side of the belt conveyor 105 are provided below the first conveying mechanism 100, and a belt conveyor 205 and a shredded paper recovery box (not shown in the figure) located at the outlet side of the belt conveyor 205 are provided below the second conveying mechanism 200.

[0081] like Fig.12As shown, the belt conveyor includes a base frame 52, a driven roller 53 and a driving roller (not marked in the figure) rotatably arranged on the base frame 52 through a bearing, a conveying belt 51 wound around the driven roller 53 and the driving roller, and a driving motor 55 for driving the driving roller to rotate. A driving pulley 54 is provided at one end of the driving roller, a driving pulley (not marked in the figure) is provided on the output shaft of the driving motor 55, and a driving belt (not shown in the figure) is wound between the driving pulley and the driving pulley 54. The driving motor 55 is electrically connected to the control device.

[0082] When the driving motor 55 is in operation, the driving roller is driven to rotate through the transmission effect between the driving pulley, the driving pulley and the driving belt, thereby driving the conveying belt 51 to work. When the shredded paper scraped off the side of the decorative panel falls, it is transported to the shredded paper recycling box through the conveying belt 51 to realize the shredded paper recycling process, thereby preventing the shredded paper from being scattered and affecting the working environment. In this embodiment, the conveying direction of the belt conveyor 105 is consistent with that of the first conveying mechanism 100, and the conveying direction of the belt conveyor 205 is opposite to that of the second conveying mechanism 200. Therefore, only one shredded paper recycling box located at the exit side of the belt conveyor 105 and the belt conveyor 205 needs to be set below the lifting mechanism 400.

[0083] Furthermore, if Figure 2 , Figure 3 , Figure 4 As shown, the automatic paper-scraping assembly line also includes a first brush 108 arranged above the first conveying mechanism 100 and located at the rear side of the positioning mechanism 103, a pressing component 106 located at the rear side of the first brush 108, a first brush 208 arranged above the second conveying mechanism 200 and located at the rear side of the positioning mechanism 203, a pressing component 206 located at the rear side of the first brush 208, and a fifth driving mechanism for driving the pressing components 106 and 206 to swing so as to abut against the top surface of the decorative panel.

[0084] By setting the first brush 108 and the first brush 208, dust and paper scraps on the upper surface of the decorative panel are removed, and the downward pressing parts 106 and the downward pressing parts 206 are set to apply downward pressure to the decorative panel. The first conveying mechanism 100 and the second conveying mechanism 200 provide support, thereby preventing the decorative panel from moving upward during horizontal movement, and after being scraped by the scraping mechanism, a better scraping effect is obtained.

[0085] Specifically, Fig.11 As shown, the pressing component includes a bracket 64, a swing shaft 63 rotatably arranged on the bracket 64 through a bearing seat, at least one pressing roller 62 fixed to the swing shaft 63, and a connecting piece 65 fixedly connected to the swing shaft 63; the fifth driving mechanism is a fifth telescopic cylinder 61 hinged to the bracket 64; the piston rod of the fifth telescopic cylinder 61 is movably connected to the connecting piece 65. The fifth telescopic cylinder 61 is electrically connected to the control device.

[0086] Among them, Fig.11 As shown, the length of the first brush 8 is long enough to sweep the top surface of the veneer. The first brush 8 is fixed to a mounting rod by bolts or welding, and the mounting rod can also be fixed to the bracket 64 by bolts or welding. The height distance between the first brush 8 and the conveying plane of the first conveying mechanism 100 and the second conveying mechanism 200 can be equal to the height of the veneer, or 1 to 5 mm less than the height of the veneer.

[0087] The cylinder body of the fifth telescopic cylinder 61 is hinged to the bracket 64, and its piston rod is hinged to the connecting member 65 through a bolt. When the veneer is ready for paper scraping, the fifth telescopic cylinder 61 works, driving the connecting member 65 to swing down, thereby causing the pressing roller 62 to swing down along with the rotation of the swing shaft 63, until the rolling surface of the pressing roller 62 contacts the top surface of the veneer, exerting a downward pressure on the veneer.

[0088] In this embodiment, two pressing rollers 62 are provided, and the pressing rollers 62 are symmetrically arranged with respect to the connecting member 65 .

[0089] Furthermore, if Fig.13 As shown, the automatic paper scraping production line also includes a plate conveying mechanism 600 disposed at the outlet end of the second conveying mechanism 200 and movable up and down, and a plate drying line 700 disposed at the outlet end of the plate conveying mechanism 600; a position detection device (not shown in the figure) is disposed at the outlet end of the plate conveying mechanism 600, and the plate conveying mechanism 600 and the position detection device are both electrically connected to the control device. A telescopic cylinder can be used to drive the plate conveying mechanism 600 to move in the height direction.

[0090] The plate conveying mechanism 600 is provided with a plurality of belt conveying components at intervals, and the plate drying rods of the plate drying line are located between adjacent belt conveying components. Since the conveying plane of the second conveying mechanism 200 is lower than that of the first conveying mechanism 100, in order to cater to the plate drying line and perform perfect cooperation, a liftable plate conveying mechanism 600 is provided.

[0091] The position detection device can be a photoelectric proximity switch. The veneer panel that has completed the paper scraping work moves from the second conveying mechanism to the plate conveying mechanism. When the position detection device detects that the veneer panel has moved into place, the control device controls the plate conveying mechanism to move upward, allowing the drying rod of the drying line to lift and transport the veneer panel to perform the drying work; when the position detection device detects that the veneer panel has left the plate conveying mechanism, the control device controls the plate conveying mechanism to descend, waiting for the next veneer panel to be conveyed from the second conveying mechanism.

[0092] In summary, the present invention provides an automatic paper scraping production line for decorative panels, which has a novel and practical design, a high degree of automation, and high working efficiency, and can complete the paper scraping work on the four sides of the decorative panels.

[0093] The present invention utilizes a plate lifting mechanism and a positioning mechanism to sequentially lift and center the decorative panel, has a better positioning effect, and performs positioning work for the scraping mechanism before scraping, so as to obtain a better scraping effect.

[0094] In addition, a lifting mechanism with a support is provided at the outlet end of the first conveying mechanism to transfer the decorative panel from the first conveying mechanism to the second conveying mechanism, and then the second conveying mechanism continues to convey and complete the scraping work on the other two sides of the decorative panel. The decorative panel is moved on the first conveying mechanism and the second conveying mechanism in a through-type manner, which greatly improves the working efficiency of the scraping assembly line.

[0095] The present invention not only completes the 90° angle transfer of the decorative panel, but also has the function of performing paper scraping treatment on the four sides of the decorative panel.

[0096] On the other hand, the scraping mechanisms arranged on both sides of the first conveying mechanism and the second conveying mechanism can move horizontally, so as to adjust the distance between the scraping mechanisms, and can perform scraping treatment on the four sides of decorative panels of different sizes, with good applicability and compatibility.

[0097] It is understandable that those skilled in the art can make equivalent substitutions or changes based on the technical solution and inventive concept of the present invention, and all these changes or substitutions should fall within the protection scope of the claims attached to the present invention.
