Description

Technical Field

[0001] The invention belongs to the technical field of PVC floor processing, and in particular relates to an embossing molding device for PVC floor processing. Background Art

[0002] PVC flooring is a lightweight flooring material made of polyvinyl chloride and its copolymer resin as the main raw materials, with fillers, plasticizers, stabilizers, colorants and other auxiliary materials added. It is produced on a sheet-like continuous substrate through a coating process or a calendering, extrusion or extrusion process.

[0003] In the production process of PVC flooring, the raw materials after mixing will be initially calendered by a calender, and by adding embossing rollers during the calendering process, textures and patterns will be formed on the surface of the floor to enhance the aesthetics and anti-slip properties. As the equipment continues to operate and the color film raw materials are continuously fed, the positional relationship of the texture on the color film relative to the overall equipment will shift due to various error factors, making the final molding quality of the product worse. In response to the above technical problems, the applicant has retrieved some existing technologies, such as the Chinese patent with patent announcement number CN117283968B, which embosses the sheet material by squeezing it with a base and a template during use. During embossing, the base and the template follow the movement of the PVC sheet material. The base and the template move back to the unembossed position, and then the embossing operation is performed again. Since the forming of the PVC sheet is continuous, but the moving stroke of the pressing plate and the base is limited, the PVC sheet is continuously moving during the embossing process. The PVC sheet is always moving during the return movement of the base and the template. At this time, when the base and the template emboss the PVC sheet again, the position of the template is closer to the end point of the template movement than the position of the template during the previous embossing. Each subsequent embossing will be closer to the end point of its stroke, that is, the embossing stroke of the base and the template becomes smaller, and the embossing time is reduced, which leads to a decrease in the subsequent embossing quality. Summary of the Invention

[0004] The purpose of the present invention is to provide an embossing forming device for PVC floor processing, aiming to solve the technical problem in the prior art that it is impossible to ensure that the embossing time at different positions of the board is the same in a continuous operation scenario, resulting in a decrease in the subsequent embossing quality.

[0005] The present invention is implemented as follows: an embossing molding device for PVC floor processing includes a feeding module, a calendering module, an embossing module and a cutting module, wherein the feeding module, the calendering module, the embossing module and the cutting module are connected in sequence; The embossing module includes a frame, in which a conveyor belt driven by a first rotating power member is rotatably installed. A supporting plate located inside the conveyor belt is provided in the frame, and the supporting plate is in sliding contact with the conveyor belt. A plurality of groups of striped molded plates for embossing the plate are provided in the frame, and the plurality of groups of striped molded plates are connected end to end in sequence and pressed on the plate. Two groups of top plates located on both sides of the conveyor belt are provided in the frame, and the striped molded plates are in contact with the top plates when moving with the plate. A circulation component for driving the striped molded plates to circulate is provided on the frame.

[0006] Further technical solution: A mounting frame is fixedly installed at the bottom of the frame, and a first adjusting screw is rotatably installed on the mounting frame. The first adjusting screw drives the first base plate of the H-shaped structure to move up and down. The respective ends of the first base plate are fixedly connected to the four corners of the supporting plate through the first connecting rod. The first connecting rod passes through the frame and is slidably connected to the frame.

[0007] Further technical solution: A first telescopic part is fixedly installed at the bottom of the frame, and the first telescopic part drives the second bottom plate of the H-shaped structure to move up and down. The ends of the second bottom plate are fixedly connected to the two ends of the top plate through a second connecting rod, and the second connecting rod passes through the frame and is slidably connected to the frame.

[0008] Further technical solution: The top plate is rotatably installed with multiple sets of limiting rollers on the surface close to the conveyor belt. The multiple sets of limiting rollers are distributed in a linear array along the length direction of the top plate. When the striped molded plate enters under the top plate, its two ends roll in contact with the limiting rollers on the top plates on both sides.

[0009] Further technical solution: Both ends of the striped molded plate are provided with horizontal plates, which are distributed along the length direction of the top plate. The horizontal plates are rotatably installed away from the surface of the striped molded plate with multiple sets of spaced rotating parts. The horizontal plates are installed on the striped molded plate through two sets of telescopic rods. Multiple sets of elastic parts are fixedly installed on the horizontal plates. The ends of the elastic parts away from the horizontal plates are fixedly connected to the striped molded plate. Two sets of second electromagnets are fixedly installed on the striped molded plate. The second electromagnets are distributed at both ends of the striped molded plate and the second electromagnets are in sliding contact with the horizontal plates on the corresponding sides. When the second electromagnets are energized, they adsorb and fix the horizontal plates.

[0010] Further technical solution: A cooling cavity is opened in the striped molded plate and the cooling cavity is connected to a water inlet pipe and a water outlet pipe. The end of the water inlet pipe away from the striped molded plate is connected to a water pump. The water pump and the end of the water outlet pipe away from the striped molded plate both extend into a water tank located on the side of the frame.

[0011] Further technical solution: The circulation component includes a placement plate, which is fixedly mounted on the side of the frame. A movable plate driven by a servo module is provided on the placement plate. A rotating plate driven by a third rotating power component is rotatably mounted on one end of the movable plate away from the placement plate. A second telescopic component is fixedly mounted on the end of the rotating plate. The second telescopic component drives the substrate to move up and down and a first electromagnet is fixedly mounted on the substrate. When the first electromagnet is energized, it adsorbs and fixes a positioning frame fixedly mounted on the striped molded plate.

[0012] Further technical solution: The substrate is fixedly mounted with cameras distributed on both sides of the first electromagnet for photographing the position of the striped molded plate below, and the substrate is fixedly mounted with a laser ranging sensor for detecting the distance the substrate moves up and down.

[0013] Further technical solution: two sets of synchronous wheels are rotatably installed on one group of the top plates, and a synchronous belt is installed to rotate with the two sets of synchronous wheels together. A plurality of L-shaped limit plates with intervals are fixedly installed on the synchronous belt. The limit plates move synchronously with the striped molded plates and the limit plates contact the blocks fixedly installed on the striped molded plates. A second rotating power component is fixedly installed on the top plate to drive one of the sets of synchronous wheels to rotate.

[0014] Further technical solution: A top frame is fixedly installed on the frame at the discharge end of the conveyor belt, a lifting frame is slidably installed on the top frame, and a second adjusting screw that drives the lifting frame to move is rotatably installed on the top frame, and a separation roller is rotatably installed on the lifting frame.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The circulation component sequentially grabs and places a set number of striped molded plates, so that the set number of striped molded plates form a complete cycle, so that multiple groups of striped molded plates can continuously emboss the plates, ensuring that the plate forming and plate embossing are carried out synchronously and continuously, thereby improving the production efficiency of the PVC floor. Moreover, the embossing time of each group of striped molded plates on the plates is the same, ensuring that each group of striped molded plates has enough time to complete the embossing operation, thereby improving the embossing quality.

[0016] 2. When the striped molded plate moves under the top plate, the cross plate is not in a fixed state, and the elastic part can always press the striped molded plate against the plate to ensure the embossing effect of the striped molded plate. When the striped molded plate finishes embossing, the cross plate is in a fixed state, and the subsequent group of striped molded plates moves to the front end of the top plate and can directly enter under the top plate. At this time, the rotating part can directly contact the top plate, avoiding the elastic part stretching and causing the rotating part to impact the top plate when the striped molded plate is used subsequently, so that the striped molded plate can stably emboss the plate, further improving the embossing quality of the striped molded plate.

[0017] 3. When the striped molded plate moves under the top plate, the limit plate is always in contact with the stop block. Since the rotation speed of the synchronous belt is the same as the rotation speed of the conveyor belt and the movement speed of the plate, the position of the striped molded plate can be limited by the limit plate to ensure that the striped molded plate always moves synchronously with the plate, avoiding slippage between the striped molded plate and the plate, resulting in poor embossing quality, and further improving the quality of embossing.

[0028] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0029] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0030] like Figure 1-Figure 7 As shown, an embossing molding device for PVC floor processing provided by the present invention includes a feeding module 1, a calendering module 2, an embossing module 3 and a cutting module 4, and the feeding module 1, the calendering module 2, the embossing module 3 and the cutting module 4 are connected in sequence; The embossing module 3 includes a frame 6, in which a conveyor belt 7 driven by a first rotating power member 8 is rotatably installed. A supporting plate 9 located in the conveyor belt 7 is provided in the frame 6. The supporting plate 9 is in sliding contact with the conveyor belt 7. A mounting frame 10 is fixedly installed at the bottom of the frame 6. A first adjusting screw 13 is rotatably installed on the mounting frame 10. The first adjusting screw 13 drives the first bottom plate 11 of the H-shaped structure to move up and down. Each end of the first bottom plate 11 is fixedly connected to the four corners of the supporting plate 9 by a first connecting rod 12. The first connecting rod 12 passes through the frame 6 and is slidably connected to the frame 6. A plurality of groups for embossing the plate are provided in the frame 6. A striped molded plate 34 is embossed, and multiple groups of striped molded plates 34 are connected end to end in sequence and pressed on the plate. Two groups of top plates 17 are provided in the frame 6 and are located on both sides of the conveyor belt 7. The striped molded plates 34 contact the top plates 17 as they move with the plate. A first telescopic member 14 is fixedly installed at the bottom of the frame 6. The first telescopic member 14 drives the second bottom plate 15 of the H-shaped structure to move up and down. The ends of the second bottom plate 15 are fixedly connected to the two ends of the top plate 17 through the second connecting rod 16. The second connecting rod 16 passes through the frame 6 and is slidably connected to the frame 6. A circulation component 49 is provided on the frame 6 to drive the striped molded plates 34 to circulate.

[0031] In actual application of this embodiment, the raw materials are mixed by the feeding module 1 and extruded into a plate through a die. The plate then enters the calendering module 2 for shaping and lamination of the color film wear-resistant layer. The plate then enters the embossing module 3. The conveyor belt 7 is driven to rotate by the first rotating power member 8 and the rotation speed of the conveyor belt 7 is made to be the same as the forming movement speed of the plate, ensuring the synchronous movement of the conveyor belt 7 and the plate, avoiding relative displacement between the conveyor belt 7 and the plate, thereby avoiding scratching the surface of the plate. After the plate moves onto the conveyor belt 7, the circulation component 49 grabs a group of striped molded plates 34. After identifying the position of the end of the plate, the circulation component 49 keeps the striped molded plates 34 moving synchronously with the plate and presses the striped molded plates 34 on the plate. The conveyor belt 7 on which the plate is placed is supported by the supporting plate 9 to ensure that there is stable support under the plate during embossing. When the supporting plate 9 is worn after long-term use, the first bottom plate 11 can be driven to move upward by the first adjusting screw 13, thereby making the supporting plate The support plate 9 moves upward. When the striped molded plates 34 partially enter under the top plate 17, the striped molded plates 34 can contact with the top plate 17 and maintain pressure on the plate. At this time, the striped molded plates 34 move synchronously with the plate under the action of pressure. According to the thickness of the plate, the second bottom plate 15 can be driven up and down by the first telescopic member 14 to adjust the height of the top plate 17. At this time, the circulation component 49 detaches from the group of striped molded plates 34 and grabs another group of striped molded plates 34. At this time, the previous group of striped molded plates 34 has not completely entered under the top plate 17. Then, the group of striped molded plates 34 is pressed on the plate and the edges of the two groups of striped molded plates 34 overlap. The above steps are repeated until the set number of groups of striped molded plates 34 are placed on the plate for embossing. After all the set number of striped molded plates 34 are put into use, when the last group of placed striped molded plates 34 partially enters under the top plate 17, the first group of placed striped molded plates 34 is about to leave under the top plate 17, and at this time, the circulation component 49 moves to the tail end of the conveyor belt 7 and grabs the first group of placed striped molded plates 34 after they leave under the top plate 17, and then drags the first group of placed striped molded plates 34 to the front end of the conveyor belt 7 for re-placement. At this time, the last group of placed striped molded plates 34 has not yet completely entered under the top plate 17. Repeating the above steps can make the set number of striped molded plates 34 form a complete cycle, so that multiple groups of striped molded plates 34 can continuously emboss the plates, ensuring that the plate forming and plate embossing are carried out synchronously and continuously, thereby improving the production efficiency of the PVC floor, and the embossing time of each group of striped molded plates 34 on the plates is the same, ensuring that each group of striped molded plates 34 has enough time to complete the embossing operation, thereby improving the embossing quality and further improving the quality of the PVC floor; The embossed boards are transported to the cutting module 4 via the cooling bridge for cutting and stacking. The boards can emit residual heat when moving on the cooling bridge. Of course, ABA co-extruded foam boards, WPC floors, and LVT floors made of PVC can also be formed and produced by this equipment.

[0032] In an example of this embodiment, the first rotating power component 8 is a first motor, and of course it can also be other components that can output rotational power, such as a hydraulic motor. The conveyor belt 7 is driven to rotate by the first motor. The first telescopic component 14 is a first electric telescopic rod, and of course it can also be other components that can actively change the length, such as a hydraulic cylinder. The top plate 17 is driven up and down by the first electric telescopic rod.

[0033] like Figures 1-9 As shown, an embossing molding device for PVC floor processing provided by the present invention is provided. A plurality of sets of limiting rollers 18 are rotatably installed on the surface of the top plate 17 close to the conveyor belt 7. The plurality of sets of limiting rollers 18 are distributed in a linear array along the length direction of the top plate 17. When the striped molded plate 34 enters under the top plate 17, its two ends roll in contact with the limiting rollers 18 on the top plates 17 on both sides.

[0034] Specifically, a horizontal plate 38 is provided at both ends of the striped molded plate 34, and the horizontal plates 38 are distributed along the length direction of the top plate 17. The horizontal plates 38 are rotatably installed away from the surface of the striped molded plate 34 with multiple groups of spaced rotating parts 39. The horizontal plates 38 are installed on the striped molded plate 34 through two groups of telescopic rods 36. Multiple groups of elastic parts 37 are fixedly installed on the horizontal plates 38. The ends of the elastic parts 37 away from the horizontal plates 38 are fixedly connected to the striped molded plate 34. The striped molded plate 34 is fixedly installed with two groups of second electromagnets 40. The second electromagnets 40 are distributed at both ends of the striped molded plate 34 and the second electromagnets 40 are in sliding contact with the horizontal plates 38 on the corresponding sides. When the second electromagnets 40 are energized, they adsorb and fix the horizontal plates 38.

[0035] Specifically, a cooling cavity is opened in the striped molded plate 34 and the cooling cavity is connected to a water inlet pipe 41 and a water outlet pipe 42. The end of the water inlet pipe 41 away from the striped molded plate 34 is connected to a water pump 43. The water pump 43 and the end of the water outlet pipe 42 away from the striped molded plate 34 both extend into a water tank 44 located on the side of the frame 6.

[0036] In actual application of this embodiment, the plate passes over the conveyor belt 7, and the conveyor belt 7 moves synchronously with the plate. In the initial state, the transverse plate 38 approaches the striped mold plate 34 and compresses the elastic member 37, and the second electromagnet 40 is energized to adsorb and fix the transverse plate 38. Then, the circulation component 49 places the striped mold plate 34 on the plate. The circulation component 49 and the striped mold plate 34 move synchronously with the plate. When the striped mold plate 34 partially enters under the top plate 17, the second electromagnet 40 is de-energized. Under the action of the elastic member 37, the transverse plate 38 moves upward and the rotating member 39 contacts the top plate 17. Then, under the action of the elastic member 37, the striped mold plate 34 can be pressed on the plate for embossing. At this time, the two ends of the striped mold plate 34 are limited and guided by the limiting roller 18 and pressed tightly on the plate. Then, the circulation component 49 releases the connection with the group of striped mold plates 34. At this time, driven by the conveyor belt 7 and the plate, the stripe mold plate 34 will move with the plate at the same time. When the stripe mold plate 34 moves to the rotating member 39 and is about to leave the top plate 17, the second electromagnet 40 is energized again to adsorb and fix the cross plate 38 to maintain the position of the cross plate 38. When the group of stripe mold plates 34 moves to the front end of the top plate 17 again and moves below the top plate 17, the second electromagnet 40 is de-energized again, so that the cross plate 38 is not in a fixed state when the stripe mold plate 34 moves below the top plate 17, and the elastic member 37 can always hold the stripe mold plate 34 in place. The pressing plate 34 is pressed tightly against the sheet material to ensure the embossing effect of the striped die pressing plate 34. When the striped die pressing plate 34 finishes embossing, the cross plate 38 is in a fixed state. Then, when the striped die pressing plate 34 subsequently moves to the front end of the top plate 17, it can directly enter under the top plate 17. At this time, the rotating member 39 can directly contact the top plate 17, avoiding the elastic member 37 extending when the striped die pressing plate 34 is subsequently used, causing the rotating member 39 to impact the top plate 17. This allows the striped die pressing plate 34 to stably emboss the sheet material, thereby improving the embossing quality of the striped die pressing plate 34. When in use, the water tank 44 is filled with cooling water. When the striped mold plate 34 is pressed on the plate, the water pump 43 and the water outlet pipe 42 are both extended into the water tank 44. At this time, the water pump 43 draws cooling water and transports it to the cooling cavity opened on the striped mold plate 34 through the water inlet pipe 41. Then the cooling water returns to the water tank 44 through the water outlet pipe 42 to complete the circulation of the cooling water. The cooling water enters the cooling cavity to cool the striped mold plate 34 and the plate, thereby accelerating the shaping of the plate and the shaping of the embossing, and further improving the quality of the plate embossing.

[0037] In one embodiment of the present invention, the elastic member 37 is a spring, and of course it can also be other elastic components such as an elastic ball, which generates downward pressure on the striped molded plate 34 through spring compression, and the rotating member 39 is a ball, and of course it can also be other rotating components such as a roller, which reduces the friction between the horizontal plate 38 and the top plate 17 through the ball.

[0038] like Figure 2-Figure 4 As shown, an embossing molding device for PVC floor processing provided by the present invention, the circulation component 49 includes a placement plate 23, and a plurality of positioning grooves 24 for placing stripe mold plates 34 are provided on the placement plate 23. The placement plate 23 is fixedly mounted on the side of the frame 6, and a movable plate 26 driven by a servo module 25 is provided on the placement plate 23. The movable plate 26 is rotatably mounted on one end away from the placement plate 23 and a rotating plate 28 driven by a third rotating power member 27 is rotatably mounted. A second telescopic member 29 is fixedly mounted on the end of the rotating plate 28. The second telescopic member 29 drives the base plate 30 to move up and down, and a first electromagnet 32 ​​is fixedly mounted on the base plate 30. When the first electromagnet 32 ​​is energized, it adsorbs and fixes the positioning frame 35 fixedly mounted on the stripe mold plate 34.

[0039] Specifically, cameras 31 for photographing the position of the stripe mold plate 34 below are fixedly mounted on the substrate 30 and are distributed on both sides of the first electromagnet 32 ​​. Laser ranging sensors 33 for detecting the vertical movement distance of the substrate 30 are fixedly mounted on the substrate 30 .

[0040] In actual application of this embodiment, in the initial state, multiple groups of stripe mold plates 34 are respectively placed in the positioning grooves 24. When embossing is required, the servo module 25 drives the movable plate 26 to move horizontally, the third rotating power member 27 drives the rotating plate 28 to rotate, and the second telescopic member 29 drives the substrate 30 to move up and down, so that the first electromagnet 32 ​​can enter the positioning frame 35 on the stripe mold plate 34. The camera 31 can capture the position of the stripe mold plate 34 and the plate under the substrate 30, thereby completing the positioning of the substrate 30. At the same time, the laser distance sensor 33 can detect the distance the substrate 30 moves up and down, thereby ensuring that the stripe mold plate 34 can be placed in the correct position later. Then, the first electromagnet 32 ​​is energized to adsorb the positioning frame 35. At this time, the group of stripe molded plates 34 is fixedly connected to the base plate 30. Then, the second telescopic member 29 contracts to make the stripe molded plates 34 leave the placement plate 23, and the rotating plate 28 rotates 180 degrees so that the stripe molded plates 34 are located directly above the conveyor belt 7. Then, the servo module 25 drives the movable plate 26 to move horizontally so that the stripe molded plates 34 move to the end of the frame 6. When the plate moves onto the conveyor belt 7 and the camera 31 detects that the stripe molded plates 34 are aligned with the end of the plate, the servo module 25 drives the movable plate 26 to move synchronously with the plate. At the same time, the second telescopic member 29 extends to make the stripe molded plates 34 move downward on the movable plate 26 and contact the plate. When the stripe molded plates 34 partially enter under the top plate 17, the first electromagnet 32 ​​is de-energized. At the same time, the first electromagnet 32 ​​continues to transport new stripe molded plates 34. When the first electromagnet 32 ​​continues to transport the new striped molded plates 34, the previous set of striped molded plates 34 moves with the plate and the striped molded plates 34 do not completely enter under the top plate 17. The steps are repeated so that the new striped molded plates 34 are pressed against the plate and the edges of the two sets of striped molded plates 34 touch each other. The above steps are repeated until all the set number of striped molded plates 34 are put into use, thereby achieving full embossing of the plate. After all the set number of striped die-pressing plates 34 are put into use, when the last group of striped die-pressing plates 34 partially enters under the top plate 17, the first group of striped die-pressing plates 34 is about to leave under the top plate 17. When the base plate 30 moves to above the first group of striped die-pressing plates 34, it leaves under the top plate 17. At this time, the base plate 30 moves downward to connect the first electromagnet 32 ​​with the first group of striped die-pressing plates 34. Then, the first group of striped die-pressing plates 34 are dragged to the front end of the conveyor belt 7 for re-placement. Repeating the above steps can form a complete cycle of the set number of striped die-pressing plates 34, so that multiple groups of striped die-pressing plates 34 can continuously emboss the plate and the embossing time of each group of striped die-pressing plates 34 on the plate is the same, ensuring that each group of striped die-pressing plates 34 has enough time to complete the embossing operation, thereby improving the embossing quality. When not in use, the first electromagnet 32 ​​sequentially absorbs the stripe molded plate 34 removed from the bottom of the top plate 17 and places it in the placement groove 23.

[0041] In one embodiment of the present invention, the third rotating power component 27 is a third motor, and of course it can also be other components that can output rotational power, such as a hydraulic motor. The third motor drives the rotating plate 28 to rotate, thereby adjusting the position of the base plate 30. The second telescopic component 29 is a second electric telescopic rod, and of course it can also be other components that can actively change the length, such as a hydraulic cylinder. The second electric telescopic rod drives the base plate 30 to move in the vertical direction.

[0042] like Figures 1-4 As shown, an embossing molding device for PVC floor processing provided by the present invention, wherein two sets of synchronous wheels 19 are rotatably installed on one set of top plates 17, and a synchronous belt 20 is installed to rotate with the two sets of synchronous wheels 19 together. A plurality of sets of spaced-apart L-shaped limit plates 21 are fixedly installed on the synchronous belt 20. The limit plates 21 move synchronously with the stripe mold plate 34 and the limit plates 21 contact with the stop blocks 48 fixedly installed on the stripe mold plate 34. A second rotating power member 22 is fixedly installed on the top plate 17 to drive one of the sets of synchronous wheels 19 to rotate.

[0043] In actual application of this embodiment, the second rotating power member 22 drives the synchronous wheel 19 to rotate, thereby causing the synchronous belt 20 to drive the multiple groups of limit plates 21 to move. The rotation speed of the synchronous belt 20 is the same as the rotation speed of the conveyor belt 7 and the movement speed of the plate. When the striped mold plate 34 partially enters the bottom of the top plate 17, one of the groups of limit plates 21 moves to a straight moving path. The movement direction of the group of limit plates 21 is the same as the movement direction of the striped mold plate 34, and the limit plates 21 contact the stoppers 48 on the group of striped mold plates 34. At this time, the first electromagnet 32 ​​is de-energized and leaves the stoppers 48 on the group of striped mold plates 34. Therefore, when the striped molded plate 34 moves under the top plate 17, the limit plate 21 is always in contact with the stop block 48. Since the rotation speed of the synchronous belt 20 is the same as the rotation speed of the conveyor belt 7 and the movement speed of the plate, the position of the striped molded plate 34 can be limited by the limit plate 21, ensuring that the striped molded plate 34 always moves synchronously with the plate, avoiding slippage between the striped molded plate 34 and the plate, resulting in poor embossing quality, and further improving the quality of embossing.

[0044] In one embodiment of the present invention, the second rotating power component 22 is a second motor, and of course it can also be other components that can output rotational power, such as a hydraulic motor. The second motor drives multiple sets of limit plates 21 to move, thereby ensuring that the striped molded plate 34 always moves synchronously with the plate.

[0045] like Figures 1-4 As shown, an embossing forming device for PVC floor processing provided by the present invention is provided. A top frame 5 is fixedly installed on the frame 6 at the discharge end of the conveyor belt 7, a lifting frame 45 is slidably installed on the top frame 5, and a second adjusting screw 46 that drives the lifting frame 45 to move is rotatably installed on the top frame 5, and a separation roller 47 is rotatably installed on the lifting frame 45.

[0046] In actual application of this embodiment, the height of the lifting frame 45 is adjusted by the second adjusting screw 46 according to the thickness of the plate, so that the separation roller 47 is in rolling contact with the upper surface of the plate. When the striped molded plate 34 is separated from the plate, the plate is restricted by the separation roller 47, thereby avoiding the striped molded plate 34 moving the plate and causing complete deformation when separating from the plate, thereby further improving the quality of the plate.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.

[0048] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
