[0036] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0037] The die-casting cloth is an auxiliary material that plays an important role in the sheet production process. It prevents the sheet from sticking to the die, facilitates the smooth release of the sheet from the die after molding, ensures a smooth and flat surface, protects the die, and extends its service life. After the sheet is processed, the die-casting cloth needs to be removed from the sheet surface. In current technology, the removal of the die-casting cloth is mostly done manually, which suffers from poor removal effect and low efficiency.

[0038] To address the problems in related technologies, this application provides a device for tearing release cloth from the surface of pultruded sheet, comprising: a frame, a guide assembly, a tearing assembly, and a release cloth winding assembly. At least two sets of guide assemblies are provided, located at the inlet and outlet ends of the frame, respectively. Each guide assembly includes a conveyor roller mounted on the frame and a pressure roller mounted on the frame via a first elastic component. The conveyor roller and pressure roller are located on opposite sides of the sheet along a first direction. The first elastic component is used to press the pressure roller and conveyor roller against the sheet surface. The conveyor roller is used to move the sheet from the inlet end to the outlet end along a second direction. The first and second directions are perpendicular to each other, the first direction being the thickness direction of the sheet, and the second direction being the direction of sheet movement. The tearing assembly is located between the inlet and outlet ends of the frame. The tearing assembly includes two tearing fixtures symmetrically arranged about the sheet. The tearing fixtures are detachably mounted on the frame via a second elastic component. A first inclined surface, inclined relative to the sheet, is provided on the side of the tearing fixture near the outlet end. As the sheet moves towards the outlet end, the distance between the sheet and the first inclined surface gradually increases. The fabric rewinding assembly is rotatably mounted on the frame and is located on the side of the tearing assembly away from the exit end. As the sheet moves toward the exit end, the fabric on the sheet surface adheres to the first inclined surface and, after being wound around the tearing fixture, is wrapped around the rotating fabric rewinding assembly to tear off the fabric from the sheet surface.

[0039] like Figure 1-4 As shown, this application provides a device for tearing release cloth from the surface of pultruded sheet metal, including a frame 1. The frame 1 serves as the supporting skeleton of the entire device, possessing sufficient strength and stability to support the various components. The frame 1 can be made of metal to enhance its strength and rigidity; the metal material can be, for example, stainless steel or aluminum. The frame structure of the frame 1 not only provides sufficient support strength but also reduces the overall weight of the frame 1. The frame 1 is provided with an inlet end and an outlet end. The sheet metal 7 to be torn off moves from the inlet end to the outlet end of the frame 1.

[0040] The direction in which the thickness of the plate 7 is located is denoted as the first direction, and the direction in which the plate 7 moves is denoted as the second direction. The first direction and the second direction are perpendicular to each other. The second direction is also the direction from the entrance end of the frame 1 to the exit end.

[0041] In such Figure 1-2In the illustrated embodiment, the frame 1 includes a platform 11 and multiple support legs 12, which are disposed at the bottom of the platform 11 to support it. The support legs 12 are fixedly connected to the platform 11, and the connection can be welding, bolting, or integral molding. The platform 11 can be made of metal, such as iron plate, and the support legs 12 can be welded from high-strength steel. A through-slot can be provided on the platform 11 to facilitate the passage and collection of torn fabric 8. Furthermore, to facilitate movement of the entire device, casters can be provided on the support legs 12. When movement is needed, the casters are used for movement; when movement is not needed, the casters can be fixed to secure the entire frame 1.

[0042] like Figure 1-2 As shown, the device for removing the release cloth from the surface of the pultruded sheet also includes a guide assembly 2. At least two sets of guide assemblies 2 are provided, and the at least two sets of guide assemblies 2 are located at the entrance end and the exit end of the frame 1, respectively, for driving the sheet 7 to move.

[0043] In other embodiments, three sets of guide components 2 are provided, with two sets located at the inlet and outlet ends respectively, and the third set located between the inlet and outlet ends. The arrangement of multiple sets of guide components 2 makes the movement of the conveyor plate 7 more stable, improving transmission stability and reliability.

[0044] like Figure 2-3 As shown, each guide assembly 2 includes a conveyor roller 21 and a pressure roller 22. The conveyor roller 21 can be mounted on the frame 1 via a bearing seat. The conveyor roller 21 rotates along its axis driven by a drive component, which can be a motor (not shown in the figure). The motor is fixedly connected to the end of the conveyor roller 21, driving the conveyor roller 21 to rotate. When the conveyor roller 21 rotates, it has static friction with the surface of the plate 7, and the static friction causes the plate 7 to move in the second direction. The pressure roller 22 is mounted on the frame 1 via a first elastic component 3, which causes the pressure roller 22 to press against the surface of the plate 7.

[0045] In such Figure 2-3 In the illustrated embodiment, along a first direction, the conveyor roller 21 and the pressure roller 22 are located on opposite sides of the plate 7. The first direction is vertical, with the conveyor roller 21 below the plate 7 and the pressure roller 22 above it. The first elastic component 3 presses the pressure roller 22 downwards, causing it to contact the plate 7. Simultaneously, the plate 7 contacts the conveyor roller 21, meaning the upper and lower sides of the plate 7 contact the pressure roller 22 and the conveyor roller 21, respectively. When the conveyor roller 21 rotates, static friction exists between it and the lower surface of the plate 7, causing the plate 7 to move along a second direction (i.e.,...). Figure 2The plate 7 moves from left to right, and as it moves, it experiences static friction with the pressure roller 22, thereby causing the pressure roller 22 to rotate. Figure 2 In the middle, the direction of movement of plate 7 is horizontal to the right.

[0046] By setting the first elastic component 3, the upper and lower sides of the plate 7 can abut against the pressure roller 22 and the conveyor roller 21 respectively, which makes it easier for the conveyor roller 21 to drive the plate 7 to move. At the same time, the pressure roller 22 and the conveyor roller 21 are located on the upper and lower sides of the plate 7 and abut against the plate 7, which can limit the direction of movement of the plate 7 and prevent the plate 7 from being unnecessarily deviated.

[0047] By setting pressure roller 22, static friction can be generated between the plate 7 and the surface of pressure roller 22 during the movement of the plate 7. Static friction can reduce the wear on the surface of plate 7 to a certain extent.

[0048] The device for removing the release cloth from the surface of the pultruded sheet also includes a tearing component 4, which is located between the inlet end and the outlet end.

[0049] In an exemplary embodiment, from the inlet end to the outlet end, the tearing component 4, one of the two sets of guide components 2, and the other of the two sets of guide components 2 are sequentially arranged on the frame 1. Thus, the tearing component 4 will first tear off the mold cloth 8 so that the board 7 conveyed by the guide component 2 are all board 7 with the mold cloth 8 already torn off.

[0050] In another exemplary embodiment, two sets of guide components 2 and tear-off components 4 are sequentially arranged on the frame 1 from the inlet end to the outlet end. Thus, when the guide components 2 convey the sheet material 7, they all contact and convey the sheet material 7 with the untorn fabric 8 removed. Therefore, the sheet material 7 conveyed by the guide components 2 is the sheet material 7 with the untorn fabric 8 removed.

[0051] In other possible embodiments, the tear-off component 4 may also be positioned between the two sets of guide components 2. For example... Figure 1 , Figure 2 and Figure 4 As shown, the tear-off assembly 4 includes two tear-off fixtures 41, which are symmetrically arranged about the sheet material 7 to... Figure 2 As shown, two tearing fixtures 41 are arranged on the upper and lower sides of 7. The tearing fixtures 41 are mounted on the frame 1 via the second elastic component 5. The second elastic component 5 is mounted on the frame 1 and the tearing fixtures 41 are detachably connected to the second elastic component 5, which facilitates the inspection and replacement of the tearing fixtures 41.

[0052] To adapt to various situations, such as adapting to different thicknesses of the sheet 7 or to situations where the sheet 7 is deformed or warped, the second elastic component 5 is provided to flexibly adjust the position of the tearing tool 41 in the first direction, so that the distance between the two tearing tools 41 can ensure that the sheet 7 passes through smoothly, thereby improving the reliability and applicability of the entire device.

[0053] In an exemplary embodiment, both tearing fixtures 41 are mounted on the frame 1 via second elastic components 5, that is, two second elastic components 5 are provided, and the second elastic components 5 are provided in a one-to-one correspondence with the tearing fixtures 41.

[0054] In another exemplary embodiment, such as Figure 4 As shown, two tearing fixtures 41 are provided. One of the tearing fixtures 41 is mounted on the frame 1 via the second elastic component 5, and the other tearing fixture 41 is mounted on the frame 1 via a connecting rod.

[0055] like Figure 2 and Figure 4 As shown, the tearing fixture 41 has a first inclined surface 411 on the side near the exit end, which is inclined relative to the plate 7. As the plate 7 moves toward the exit end, the distance between the plate 7 and the first inclined surface 411 gradually increases. The first inclined surfaces 411 of the two tearing components 4 are arranged opposite each other, thus forming a shape similar to a trumpet.

[0056] exist Figure 2 and Figure 4 In the embodiment shown, with reference to the orientation shown in the figure, the first inclined surface 411 is located on the right side of the tearing tool 41. The first inclined surface 411 is inclined relative to the upper surface of the plate 7, and the first inclined surface 411 and the upper surface of the plate 7 are set at an acute angle. When the plate 7 moves to the right, the distance between the plate 7 and the first inclined surface 411 gradually increases.

[0057] By setting the first inclined plane 411, even if the plate 7 warps to a certain extent, it can still pass through smoothly, reducing the jamming that occurs during the movement of the plate 7.

[0058] like Figure 1-2 As shown, the fabric rewinding assembly 6 is mounted on the frame 1. The fabric rewinding assembly 6 is located on the side of the tearing assembly 4 furthest from the exit end, i.e., in the direction from the inlet end to the outlet end. The fabric rewinding assembly 6 and the tearing assembly 4 are arranged sequentially. The fabric rewinding assembly 6 is capable of rotation, and while rotating, it rewinds the fabric 8 that has detached from the board 7.

[0059] Before using this device, place the sheet material 7 on the guide assembly 2 at the inlet end, so that the sheet material 7 is located between the conveyor roller 21 and the pressure roller 22. The conveyor roller 21 rotates and drives the sheet material 7 to move along the second direction. When the end of the sheet material 7 passes the tearing assembly 4, that is, when the end of the sheet material 7 is located near the outlet end of the tearing assembly 4, control the conveyor roller 21 to stop rotating, manually tear off a distance of the mold cloth 8 at the end of the sheet material 7, so that the mold cloth 8 adheres to the first inclined surface 411. After passing through the tearing fixture 41, the end of the mold cloth 8 is fixed on the mold cloth winding assembly 6. Then, the fabric take-up assembly 6 is controlled to rotate, causing the fabric 8 to wrap around the fabric 8 tear-off assembly 4. Simultaneously, the conveyor roller 21 continues to operate, driving the sheet 7 to move along the second direction. This causes the fabric 8 on the surface of the sheet 7 to adhere to the first inclined surface 411 and wrap around the tear-off fixture 41, then, as the fabric take-up assembly 6 rotates, it wraps around the fabric take-up assembly 6, thus achieving the tearing off of the fabric 8 from the surface of the sheet 7 and its wrapping around the fabric take-up assembly 6. As the sheet 7 moves, the fabric 8 on the surface of the sheet 7 passes through the tear-off assembly 4 and wraps around the fabric take-up assembly 6, thereby achieving the purpose of tearing off the fabric 8 from the surface of the sheet 7. Figure 2 As shown, the arrows indicate the direction of movement of the sheet 7 and the die cloth 8.

[0060] In this application, as the sheet 7 moves, the liner 8 on its surface bypasses the tearing fixture 41 and wraps around the liner winding assembly 6 in the opposite direction of the sheet 7's movement, improving the efficiency of tearing the liner 8. The liner winding assembly 6 not only winds up and collects the torn liner 8 but also provides tension to the liner 8 adhered to the sheet, allowing the liner 8 to be easily torn from the surface of the sheet 7. By setting the first inclined surface 411, the liner 8 separates more smoothly from the surface of the sheet 7, ensuring that the pulling force at the moment of tearing is moderate, avoiding excessive force causing the liner 8 to tear, or insufficient force preventing the liner 8 from being completely torn off, thereby improving the tearing effect of the liner 8.

[0061] In some embodiments, such as Figure 2 and Figure 4 As shown, a second inclined surface 412 is provided on the side of the tearing tool 41 away from the first inclined surface 411. The second inclined surface 412 is parallel to the first inclined surface 411. Both sides of the tearing tool 41 along the first direction are parallel to the plate 7.

[0062] exist Figure 2 and Figure 4In the illustrated embodiment, with reference to the orientation shown in the figure, the first inclined surface 411 is located on the right side of the tearing fixture 41, and the second inclined surface 412 is located on the left side of the tearing fixture 41. Both the upper and lower sides of the tearing fixture 41 are parallel to the sheet material 7, making the cross-section of the tearing fixture 41 a parallelogram. The first inclined surface 411 and the two sides have a smooth transition, i.e., rounded corners, and the second inclined surface 412 also has a smooth transition, i.e., rounded corners, allowing the molding cloth 8 to slide smoothly on the tearing fixture 41 and preventing scratches on the molding cloth 8. The parallelism of the two sides to the sheet material 7 prevents scratches when the molding cloth 8 adheres to the two sides.

[0063] When the first inclined plane 411 fails, since the second inclined plane 412 is also provided, the tearing tool 41 can be rotated 180° and continued to be used, thereby improving the utilization rate of the tearing tool 41, reducing the replacement time of parts, and increasing the service life of the device.

[0064] In some embodiments, the first elastic component 3 includes a first bracket 31, a first guide rod 32, a first support 33, and a first spring 34, with the first bracket 31 disposed on the frame 1. Figure 1-3 In the illustrated embodiment, the first support 31 may include a first horizontal plate and two first vertical plates. The two first vertical plates are fixedly connected to the frame 1, and are respectively fixedly connected to the bottom of both sides of the first horizontal plate to support the first horizontal plate. The fixed connection can be achieved by welding, bolting, or integral molding. A through hole is provided on the first horizontal plate to facilitate the passage of the first guide rod 32.

[0065] The first guide rod 32 is rod-shaped, passes through the first bracket 31, and slides along the first direction. Figure 1-3 In the illustrated embodiment, the first guide rod 32 passes through the through hole. The first guide rod 32 extends along a first direction to... Figure 2 Based on the orientation shown in the figure, the first guide rod 32 slides vertically in the through hole.

[0066] like Figure 1-3 As shown, the end of the first guide rod 32 closest to the plate 7 is connected to the first bracket 33, and the connection method is welding, bolting, or integral molding. Figure 1 In the first embodiment shown, the top end of the first guide rod 32 is located above the first horizontal plate, and the bottom end of the first guide rod 32 is located below the first horizontal plate and connected to the first bracket 33. The first guide rod 32 drives the first bracket 33 to slide vertically.

[0067] like Figure 1-3As shown, the first spring 34 is sleeved outside the first guide rod 32, and its two ends abut against the first bracket 31 and the first support 33 respectively. The first spring 34 is in a compressed state and applies force to the first support 33 to bring it closer to the plate 7. The two ends of the pressure roller 22 are rotatably mounted on the first support 33. Figure 2-3 In the embodiment described above, the first spring 34 exerts a downward force on the first bracket 33, causing the first bracket 33 to drive the pressure roller 22 to press against the surface of the plate 7.

[0068] exist Figure 1-2 In the first embodiment shown, two first guide rods 32 and two first springs 34 are provided. The two first springs 34 are respectively sleeved on the outside of the two first guide rods 32. The two first guide rods 32 extend along the first direction, and the first springs 34 are in a compressed state. The arrangement of the two first guide rods 32 and the two first springs 34 facilitates the first bracket 33 to be subjected to a uniform force, thereby driving the pressure roller 22 to more stably contact the surface of the plate 7.

[0069] The first bracket 31 serves as a support component for the first elastic component 3, possessing sufficient strength and stability to support the various components. The first guide rod 32 is designed to guide the movement, ensuring that the direction of the elastic force of the first spring 34 is always along the first direction, preventing the direction of the elastic force of the first spring 34 from shifting. This ensures that the first bracket 33 is always subjected to the elastic force from the first spring 34, thereby driving the pressure roller 22 to abut against the surface of the plate 7.

[0070] In some embodiments, such as Figure 1-3 As shown, the first elastic component 3 also includes a limiting block 35. The end of the first guide rod 32 furthest from the first bracket 33 passes through the first support 31 and connects to the limiting block 35. The connection method can be welding, screwing, or integral molding. The limiting block 35 is disposed on the first guide rod 32, and along the first direction, the limiting block 35 and the first bracket 33 are respectively located on both sides of the first support 31. Figure 2-3 In the illustrated embodiment, the limiting block 35 is connected to the top of the first guide rod 32. The limiting block 35 is located above the first bracket 31. The setting of the limiting block 35 restricts the sliding range of the first guide rod 32, allowing the first guide rod 32 to slide within a specified range, which facilitates control and operation.

[0071] like Figure 1 , Figure 2 and Figure 4 As shown, the second elastic element includes a second bracket 51, a second guide rod 52, and a second spring 53. The second bracket 51 is mounted on the frame 1. Figure 1-2In the described embodiment, the second support 51 includes a second horizontal bar and two second vertical bars. The two second vertical bars are vertically mounted on the frame 1, and the second horizontal bar is fixedly mounted on the top of the two second vertical bars. The connection method between the second horizontal bar and the second vertical bars, as well as the connection method between the two second vertical bars and the frame 1, can be welding, bolting, or integral molding.

[0072] like Figure 1 , Figure 2 and Figure 4 As shown, the second guide rod 52 is rod-shaped, and its length direction is the same as the first direction. The second guide rod 52 passes through the second bracket 51 and slides along the first direction. The end of the second guide rod 52 near the plate 7 is detachably connected to the tearing fixture 41, and the connection method can be a bolt connection. The second guide rod 52 can drive the tearing fixture 41 to slide along the first direction.

[0073] exist Figure 1 , Figure 2 and Figure 4 In the embodiment shown, two second guide rods 52 and two second springs 53 are provided. The two second guide rods 52 correspond one-to-one with the two second springs 53. Both second guide rods 52 are vertically arranged. The bottom of both second guide rods 52 are detachably connected to the tearing fixture 41. The top of the second guide rod 52 passes through the second bracket 51. The second guide rod 52 drives the tearing fixture 41 to slide vertically closer to the plate 7.

[0074] The second guide rod 52 is detachably connected to the tearing fixture 41, which facilitates the replacement of the tearing fixture 41 and makes the device easy to inspect and maintain.

[0075] The second spring 53 is sleeved on the outside of the second guide rod 52, and the two ends of the second spring 53 abut against the second bracket 51 and the tearing tool 41 respectively.

[0076] The second bracket 51 is a supporting component for the second elastic assembly 5, possessing sufficient strength and stability to support all components. The second guide rod 52 serves a guiding function, ensuring that the elastic force of the second spring 53 is always along the first direction, preventing the elastic force of the second spring 53 from deviating. When the sheet metal 7 deforms and warps, the second spring 53 allows the position of the tearing tool 41 to adapt to the warped sheet metal 7. Therefore, this device can adapt to sheet metal 7 of different shapes.

[0077] In some embodiments, the second guide rod 52 is a screw, and the second elastic component 5 further includes a nut 54. One end of the screw is connected to the tearing tool 41, and the other end of the screw passes through the second bracket 51 and is screwed to the nut 54.

[0078] In some embodiments, the tearing fixture 41 is provided with a threaded hole, and the screw is screwed into the threaded hole. The screw is detachably mounted on the tearing fixture 41 through the threaded hole, making it easier to disassemble and assemble the tearing fixture 41.

[0079] In some embodiments, such as Figure 1-2 As shown, the fabric winding assembly 6 is configured in two sets, with the two sets of fabric winding assemblies 6 located on both sides of the sheet 7 along the first direction. The fabric winding assembly 6 includes a winding roller 62 and a guide roller 61, which are arranged sequentially from the inlet end to the outlet end. The distance between the winding roller 62 and the sheet 7 along the first direction is greater than the distance between the guide roller 61 and the sheet 7. The torn fabric 8 is guided by the guide roller 61 and then wound around the winding roller 62. The first side of the guide roller 61 is the side closer to the sheet 7, and the distance between the first side of the guide roller 61 and the sheet 7 is the first distance. The distance between the side of the tearing fixture 41 away from the sheet 7 and the sheet 7 is the second distance. The first distance is less than the second distance.

[0080] The take-up roller 62 is existing technology. The take-up roller 62 includes a power component that enables the take-up roller 62 to rotate and wrap the torn molded fabric 8 layer by layer around its own surface, collect the torn molded fabric 8, and the take-up roller 62 can provide tension to ensure that the torn molded fabric 8 is tightly wrapped on the take-up roller 62.

[0081] The guide roller 61 is used to guide the direction of the die fabric 8, and the guide roller 61 also has a certain function of adjusting the tension of the die fabric 8.

[0082] In such Figure 2 In the illustrated embodiment, the take-up roller 62, guide roller 61, and tearing assembly 4 are arranged sequentially from left to right. In the fabric take-up assembly 6 located above the sheet 7, the height of the take-up roller 62 is greater than the height of the guide roller 61, and the bottom side height of the guide roller 61 is lower than the top side height of the tearing fixture 41. The torn fabric 8 adheres to the first inclined surface 411 and is wound around the top of the tearing fixture 41, then wound around the bottom side of the guide roller 61, and finally wrapped around the rotating take-up roller 62.

[0083] In some embodiments, the two conveyor rollers 21 are connected by a chain drive (not shown in the figure). A sprocket is provided on the same side of both conveyor rollers 21, and the two sprockets are connected by a chain to form a chain drive. A motor is connected to the end of one of the conveyor rollers 21, and the motor drives the conveyor roller 21 to rotate. The rotation of one conveyor roller 21 by the motor simultaneously drives the sprocket connected to it to rotate. The sprocket drives the chain to rotate, the chain drives the other sprocket to rotate, and the other sprocket drives the other conveyor roller 21 to rotate, thus realizing that one motor drives the rotation of both conveyor rollers 21.

[0084] The chain drive connection of the two conveyor rollers 21 can reduce the cost of the device, reduce energy consumption, and has a simple structure that is easy to maintain.

[0085] In some embodiments, the included angle between the first inclined plane 411 and the second direction is 40° to 50°. Specifically, the included angle between the first inclined plane 411 and the second direction is 45°. The setting of the included angle facilitates the smooth separation of the molding cloth 8 from the surface of the plate 7 during the movement of the plate 7, ensuring that the instantaneous force of tearing is appropriate and the molding cloth 8 is removed smoothly.
