[0002] Impact-resistant PVC membrane, also known as polyester fiber reinforced polyvinyl chloride (PVC) waterproof membrane, is a thermoplastic PVC membrane. It uses polyester fiber fabric as reinforcement and uses a special extrusion coating process to tightly combine the double-sided polyvinyl chloride plastic layer and polyester fiber fabric to form a waterproof membrane with excellent impact resistance.

[0004] However, traditional impact-resistant PVC coils are prone to deviation during the unwinding process, which may cause the coil position on the unwinding roller to shift, making it impossible for the coil to be unwound accurately along the set path. At the same time, the friction between the coil and the unwinding roller increases, thereby aggravating the wear of the unwinding roller, and the coil on the winding roller is not wound evenly, resulting in problems such as misalignment, overlap or gaps at the edges of the coil. This not only affects the appearance quality of the coil, but may also affect the stability and accuracy of the subsequent processing process, greatly affecting the production schedule and increasing maintenance costs. Utility Model Content

[0005] The utility model discloses a material discharge structure for processing impact-resistant PVC coils, aiming to solve the problem that conventional impact-resistant PVC coils are prone to deviation during the material discharge process, which may cause the position of the coil on the discharge roller to shift, making it impossible for the coil to be discharged accurately along a set path, and at the same time, the friction between the coil and the discharge roller increases, thereby aggravating the wear of the discharge roller, and the coil on the winding roller is not wound evenly, resulting in the problem of misalignment, overlap or gap of the coil edge, which not only affects the appearance quality of the coil, but also may affect the stability and accuracy of the subsequent processing process, greatly affect the production progress, and increase the technical problem of maintenance cost.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] The material discharge structure for processing impact-resistant PVC coiled materials comprises a base, wherein the top outer wall of the base is provided with four mounting seats, wherein a material discharge roller is provided between two of the mounting seats, wherein a material collection roller is provided between two of the mounting seats, and further comprises:

[0010] The second adjusting mechanism is located at one side of the deviation correcting mechanism.

[0011] When the impact-resistant PVC coil is unloaded, the first adjusting mechanism is used to adjust and limit the impact-resistant PVC coil according to the impact-resistant PVC coil of different widths, so as to adjust the distance between the two mounting frames, and then the impact-resistant PVC coil passes through the inside of the limiting clamp, and then the motor is started, and the output shaft of the motor drives the second connecting rod to rotate, thereby driving the first connecting rod and the mounting rod to move linearly, thereby realizing the movement of the two gears on the lower tooth plate. Since the teeth of the gear and the upper tooth plate are meshed with each other, the upper tooth plate will be pushed to move synchronously during the movement of the gear, and the moving rod and the slider will move synchronously on the inner wall of the slide groove and provide support and limiting effects for it.

[0013] When in use, due to the mutual meshing between the teeth of the upper tooth plate and the gear, when the gear is connected with the correction mechanism, it drives the gear to move on the lower tooth plate, thereby pushing the upper tooth plate to move synchronously. Due to the connection between the moving rod and the upper tooth plate and the sliding connection of the slider in the slide groove, when the upper tooth plate moves, it provides moving power for the moving rod and the slider. The roller is arranged to reduce the friction between the upper and lower surfaces of the impact-resistant PVC coil, so as to avoid affecting the appearance quality of the impact-resistant PVC coil.

The components of the embodiments of the present application usually described and marked in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

[0026] The unwinding structure for processing impact-resistant PVC coils disclosed by the utility model is mainly used in conventional impact-resistant PVC coils, which are prone to the phenomenon of coil deviation during the unwinding process, which may cause the coil position on the unwinding roller to shift, making it impossible for the coil to be accurately unwound along the set path, and at the same time, the friction between the coil and the unwinding roller increases, thereby aggravating the wear of the unwinding roller, and the coil on the winding roller is unevenly wound, resulting in problems such as misalignment, overlap or gaps at the edges of the coil, which not only affects the appearance quality of the coil, but may also affect the stability and accuracy of the subsequent processing process, greatly affecting the production schedule and increasing the maintenance cost.

[0027] Reference Figure 1 , Figure 2 and Figure 3 The material discharge structure for processing impact-resistant PVC coils includes a base 1, four mounting seats 2 are arranged on the top outer wall of the base 1, a material discharge roller 3 is arranged between two mounting seats 2, a material collection roller 4 is arranged between two mounting seats 2, and further includes:

[0028] The first adjustment mechanism is located inside the base 1;

[0029] Correction mechanism: Located at the top of the first adjustment mechanism, the correction mechanism includes two mounting frames 5 and two gears 12. The top outer wall of the mounting frame 5 is provided with a lower tooth plate and two fixed frames 16. A motor 17 is provided on the outer wall of one side of one of the fixed frames 16. The output shaft of the motor 17 passes through the outer wall of one side of one of the fixed frames 16 and is fixedly connected with a second connecting rod 15. One end of the second connecting rod 15 is hinged with a first connecting rod 14. Slide grooves 10 are provided on the outer walls of both sides of the mounting frame 5. The inner wall of the slide groove 10 is slidably connected with a guide assembly. The two gears 12 are meshed with the teeth of the lower tooth plate. One end of the first connecting rod 14 is hinged with a mounting rod 13. The two ends of the mounting rod 13 are connected to the outer wall of one side of the two gears 12 near the center of the circle through bearings.

[0030] The second adjusting mechanism: located on one side of the deviation correcting mechanism.

[0031] Among them, the guide assembly includes two upper toothed plates 6, and moving rods 9 are provided at the four corners of the upper toothed plates 6. Slide blocks are provided on the outer walls of one side of the moving rods 9. The slide blocks are slidably connected to the inner walls of the slide grooves 10. The teeth of the upper toothed plates 6 are meshed with the two gears 12. A limiting clip 11 is provided on the outer wall of one side of the upper toothed plates 6. A plurality of rollers 19 are provided on the top inner walls and bottom inner walls of the limiting clip 11. When in use, due to the mutual meshing between the teeth of the upper toothed plates 6 and the gears 12, when the gears 12 are connected by the deviation correction mechanism, the gears 12 are driven to move on the lower toothed plates, thereby pushing the upper toothed plates 6 to move synchronously. Due to the connection between the moving rod 9 and the upper toothed plates 6 and the sliding connection of the slide blocks in the slide grooves 10, when the upper toothed plates 6 move, the moving rods 9 and the slide blocks are provided with moving power. The rollers 19 are provided to reduce the friction between the upper and lower surfaces of the impact-resistant PVC coils to avoid affecting the appearance quality of the impact-resistant PVC coils.

[0032] In a specific implementation process, the lower tooth plate is located near the center of the top outer wall of the mounting frame 5, and the upper tooth plate 6 and the lower tooth plate have the same length.

[0033] Specifically, when the impact-resistant PVC coil is unloaded, the first adjustment mechanism is used to adjust the limit position of the impact-resistant PVC coil according to the different widths of the impact-resistant PVC coil, so as to adjust the distance between the two mounting frames 5, and then the impact-resistant PVC coil passes through the inside of the limit clamp 11, and then the motor 17 is started, and the output shaft of the motor 17 drives the second connecting rod 15 to rotate, thereby driving the first connecting rod 14 and the mounting rod 13 to move linearly, and then the two gears 12 are moved on the lower tooth plate. Since the teeth of the gear 12 and the upper tooth plate 6 are meshed with each other, the gear 12 will push the upper tooth plate 6 during the movement process. Synchronously move, and the moving rod 9 and the slider move synchronously on the inner wall of the slide groove 10, and provide support and limiting effects therefor. When the upper tooth plate 6 moves, it will drive the limiting clamp 11 to move synchronously. Therefore, when the impact-resistant PVC coil is unloaded, the limiting clamp 11 can move back and forth in a straight line and limit and guide the edge of the impact-resistant PVC coil, thereby preventing the impact-resistant PVC coil from positionally shifting during unloading, allowing the impact-resistant PVC coil to be unloaded along a set path, reducing friction with the unloading roller 3 and the receiving roller 4, improving production efficiency, and reducing maintenance costs.

[0034] Reference Figure 1 and Figure 4 In a preferred embodiment, the first adjustment mechanism includes two first threaded rods 20, a through groove is opened inside the base 1, and two limit grooves 7 are opened on the top outer wall of the base 1, and the limit groove 7 is communicated with the through groove. One end of the first threaded rod 20 is connected to the inner wall of one side of the base 1 through a bearing, and the end of the first threaded rod 20 away from the inner wall of the base 1 is provided with a first knob 8. The circumferential outer wall of the first threaded rod 20 is threadedly connected to two limit rods 18, and the limit rods 18 are slidably connected to the inner wall of the limit groove 7.

[0035] Among them, the circumferential outer wall of the first threaded rod 20 is provided with two threads in opposite directions. This arrangement makes it convenient for the two limit rods 18 on the first threaded rod 20 to approach or move away from each other when the operator turns the first knob 8, thereby flexibly adjusting the distance between the two limit rods 18.

[0036] In the specific implementation process, one end of the limiting rod 18 is in a "concave" structure near the top outer wall. This arrangement facilitates the second adjustment mechanism to slide on the inner walls on both sides of the limiting rod 18 and limit the second adjustment mechanism at the same time.

[0037] Specifically, when in use, the operator can simultaneously rotate the two first knobs 8, thereby rotating the two first threaded rods 20, and then adjust the distance between the two limit rods 18 on the same first threaded rod 20 according to the actual width of the impact-resistant PVC coil. Under the limiting action of the limit groove 7, the two limit rods 18 slide left and right along the inner wall of the limit groove 7.

[0038] Reference Figure 1 and Figure 4 In a preferred embodiment, the second adjustment mechanism includes four second threaded rods 21, one end of the second threaded rod 21 is connected to the top outer wall of the limiting rod 18 through a bearing, and the end of the second threaded rod 21 away from the limiting rod 18 is provided with a second knob, and the circumferential outer wall of the second threaded rod 21 is threadedly connected to a support block 22, and the support block 22 is slidably connected to the inner wall on the opposite side of the limiting rod 18, and the support block 22 is fixedly connected to the mounting frame 5.

[0039] Specifically, when in use, the second knob is first turned to drive the second threaded rod 21 to rotate, and then the support block 22 moves up and down on the circumferential outer wall of the second thread, thereby realizing the synchronous up and down movement of the correction mechanism. The movement of the support block 22 and the use of the limit clamp 11 can realize the anti-impact PVC coil tensioning and improve the stability of unwinding and winding.

[0040] Working principle: When the impact-resistant PVC coil is unloaded, the first adjustment mechanism is used to adjust and limit the impact-resistant PVC coil according to the different widths of the impact-resistant PVC coil, so as to adjust the distance between the two mounting frames 5, and then the impact-resistant PVC coil is passed through the inside of the limiting clamp 11, and then the motor 17 is started. The output shaft of the motor 17 drives the second connecting rod 15 to rotate, thereby driving the first connecting rod 14 and the mounting rod 13 to move linearly, thereby realizing the movement of the two gears 12 on the lower tooth plate. Since the teeth of the gear 12 and the upper tooth plate 6 are meshed with each other, the upper tooth plate 6 will be pushed to move synchronously during the movement of the gear 12. At the same time, the moving rod 9 and the slider move synchronously on the inner wall of the slide groove 10 and provide support and limiting effects for it. When the upper tooth plate 6 moves, it will drive the limiting clamp 11 to move synchronously. Therefore, when the impact-resistant PVC coil is unloaded, the limiting clamp 11 can move back and forth in a straight line and limit and guide the edge of the impact-resistant PVC coil.

The replacement can be a replacement of part of the structure, device, method step, or a complete technical solution. Equivalent replacement or change based on the technical solution of the utility model and its utility model concept should be included in the protection scope of the utility model.
