Description

Technical Field

[0001] This application relates to the technical field of edge trimming devices for geomembrane production, specifically an edge trimming device for geomembrane production. Background Technology

[0002] Edge trimming devices for geomembrane production are specialized equipment used in the geomembrane production process to cut and trim the edges of the membrane material, removing burrs, flash, or irregular edges generated during extrusion, stretching, and other processes.

[0003] Chinese utility model patent with publication number CN222537857U discloses a trimming device for geomembrane production, which relates to the field of geomembrane production technology. By operating an electric bidirectional chute, two moving blocks can be driven to move simultaneously to both sides or simultaneously to the middle, thereby adjusting the cutting width.

[0004] However, when adjusting the side distances of the geomembrane on both sides using the above-mentioned device, it can only move synchronously, meaning that the side distances on both sides can only be equal. It is not convenient to make independent adjustments according to actual needs. For example, if the width of the rough edges on both sides is different, the side distances that need to be cut off will be different, which cannot be achieved by the above-mentioned device.

[0005] Therefore, this application provides a trimming device for geomembrane production to solve the above-mentioned problems. Utility Model Content

[0006] This application provides a trimming device for geomembrane production, which aims to solve the problem mentioned in the background art that the existing trimming devices for geomembrane production can only adjust the cutting edge distance on both sides of the geotextile synchronously, and cannot be adjusted independently to meet actual needs.

[0007] To achieve the above objectives, this application provides the following technical solution: a trimming device for geomembrane production, comprising a workbench, with an unwinding roller and a take-up roller rotatably mounted at both ends of the workbench, and two driving components for driving the unwinding roller and the take-up roller respectively fixedly mounted at both ends of the workbench, with two tensioning rollers rotatably mounted at the center of the workbench, and an edge-adjusting cutting blade positioned on the workbench corresponding to the position between the two tensioning rollers, the edge-adjusting cutting blade comprising an adjustment groove opened at the center of the workbench, two blade holders symmetrically arranged on both sides of the adjustment groove and moving laterally within the adjustment groove, and a push rod fixedly mounted on the side of the workbench with its movable end connected to the blade holder on the same side, wherein each blade holder has a cutting blade vertically fixed on it. In this way, by setting an adjustable cutting blade, and using the cooperation of the adjusting groove, two independently movable blade holders and the push rod, the cutting edge distance on both sides can be independently adjusted according to the actual needs such as the different rough edge widths on both sides of the geomembrane. This solves the problem that the existing device can only adjust the edge distance on both sides at the same time and cannot adapt to the actual diverse needs, thus improving the flexibility and accuracy of edge cutting.

[0008] Preferably, the tool holder has limiting sliders on both sides, and the inner walls of both sides of the adjustment groove are provided with sliding grooves that are slidably connected to the limiting sliders.

[0009] Preferably, the drive assembly includes two gearboxes fixedly mounted on the sides of both ends of the worktable and whose output shafts are respectively connected to the unwinding roller and the winding roller, and a servo motor fixedly mounted on the gearboxes and whose output shaft is connected to the corresponding input shaft of the gearbox.

[0010] Preferably, both ends of the tension roller are rotatably connected to bearing seats, and a tension sensor connected to the bottom of the bearing seat is fixedly installed on the worktable.

[0011] Preferably, the output end of the tension sensor, the input end of the servo motor, and the input end of the push rod are all connected to an external control system.

[0012] Preferably, a waste outlet is provided at the rear end of the cutting area on both sides of the workbench, and a waste collection box is placed below the waste outlet. A waste guiding mechanism is provided in the waste outlet to guide the waste into the waste collection box.

[0013] Preferably, the waste guiding mechanism includes a pair of clamping rollers rotatably connected in the waste inlet for clamping waste and conveying it downward by rotation, a waste collection motor fixedly installed on the side of the workbench with its output shaft connected to one of the clamping rollers, and a pair of transmission gears fixedly connected to the ends of the two clamping rollers away from the waste collection motor and meshing with each other.

[0014] This edge-cutting device for geomembrane production, by setting an adjustable edge-distance cutting blade, and utilizing the cooperation of an adjustment groove, two independently movable blade holders, and a push rod, can independently adjust the cutting edge distance on both sides according to actual needs such as different rough edge widths on both sides of the geomembrane. This solves the problem that existing devices can only adjust the edge distance on both sides simultaneously and cannot adapt to diverse actual needs, thus improving the flexibility and accuracy of edge cutting.

[0015] This edge-cutting device for geomembrane production automatically transports waste to a waste collection box via a waste guiding mechanism, greatly reducing manual operation, lowering labor intensity, improving production efficiency, preventing waste from accumulating on the workbench and affecting the flatness of the geomembrane, and ensuring cutting quality.

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] Example 1

[0025] This embodiment provides a trimming device for geomembrane production, such as... Figures 1-3As shown, the edge trimming device for geomembrane production includes a workbench 1. A roll unwinding roller 2 and a roll rewinding roller 3 are rotatably mounted at both ends of the workbench 1. Two drive components 4, used to drive the roll unwinding roller 2 and the roll rewinding roller 3, are fixedly installed at both ends of the workbench 1. Two tension rollers 5 are rotatably mounted in the center of the workbench 1. An edge-adjusting cutter 6 is positioned on the workbench 1 at a location corresponding to the two tension rollers 5. The edge-adjusting cutter 6 includes an adjustment groove 11 located in the center of the workbench 1, two cutter holders 61 symmetrically arranged on both sides of the adjustment groove 11 and moving laterally within the adjustment groove 11, and a push rod 62 fixedly mounted on the side of the workbench 1 with its movable end connected to the cutter holder 61 on the same side. Each cutter holder 61 has a cutting blade vertically fixed on it.

[0026] In use, the unwinding roller 2 rotates under the drive of the corresponding drive component 4, releasing the geomembrane to be cut. The geomembrane passes through the two tensioning rollers 5 in the center of the workbench 1, which keep the geomembrane taut. Finally, the geomembrane is wound up by the winding roller 3 under the drive of the corresponding drive component 4, thus realizing the transfer of the geomembrane on the workbench 1. When it is necessary to adjust the cutting edge distance according to the actual needs such as the different rough edge widths on both sides of the geomembrane, the push rod 62 fixedly installed on the side of the workbench 1 is operated. Since the movable end of the push rod 62 is connected to the cutter holder 61 on the same side, the push rod 62 can push the cutter holder 61 to move laterally in the adjustment groove 11 opened in the center of the workbench 1. Since there are two cutter holders 61 symmetrically arranged on both sides of the adjustment groove 11, the positions of the two cutter holders 61 can be adjusted independently, thereby adjusting the position of the vertical cutting blade fixed on the cutter holder 61, realizing the independent adjustment of the cutting edge distance on both sides of the geomembrane.

[0027] Specifically, the tool holder 61 has limiting sliders 611 on both sides, and the inner walls of both sides of the adjustment groove 11 are provided with sliding grooves 111 that are slidably connected to the limiting sliders 611. When the push rod 62 pushes the tool holder 61 to move laterally in the adjustment groove 11, the limiting sliders 611 on both sides of the tool holder 61 will slide along the sliding grooves 111 on both sides of the adjustment groove 11. The cooperation between the limiting sliders 611 and the sliding grooves 111 provides a guiding effect for the movement of the tool holder 61, so that the tool holder 61 can only move in a straight line along the direction of the sliding grooves 111, while limiting the swaying and offset of the tool holder 61 in the direction perpendicular to the movement direction.

[0028] Specifically, the drive assembly 4 includes two gearboxes 41 fixedly installed on the sides of both ends of the workbench 1, with their output shafts connected to the unwinding roller 2 and the take-up roller 3 respectively, and a servo motor 42 fixedly installed on the gearboxes 41 with its output shaft connected to the input shaft of the corresponding gearbox 41. The servo motor 42 has high-precision speed and position control capabilities. In conjunction with the speed reduction and torque increase function of the gearboxes 41, it can accurately control the speed and torque of the unwinding roller 2 and the take-up roller 3, ensuring that the geomembrane maintains stable tension during transmission and avoiding the impact on cutting quality due to excessive or insufficient tension.

[0029] Furthermore, both ends of the tension roller 5 are rotatably connected to bearing seats 51. A tension sensor 52, which is connected to the bottom of the bearing seat 51, is fixedly installed on the worktable 1. The output end of the tension sensor 52, the input end of the servo motor 42, and the input end of the push rod 62 are all connected to the external control system. The tension sensor 52 detects the pressure borne by the bearing seat 51 in real time and converts it into an electrical signal output. The external control system receives the electrical signal output by the tension sensor 52, analyzes and processes the signal, and compares it with the preset tension value and the actual detected value. If there is a deviation between the actual tension and the preset value, the external control system will issue a corresponding control signal to adjust the speed of the servo motor 42, thereby changing the unwinding or rewinding speed to adjust the tension of the geomembrane. At the same time, the external control system can also control the push rod 62 to adjust the position of the cutter holder 61 according to production needs, so as to realize the dynamic adjustment of the cutting edge distance.

[0030] Example 2

[0031] Unlike Embodiment 1, the cut waste falls to both sides and can only be collected manually. Moreover, the weight of the accumulated waste can easily affect the flatness of the geomembrane and cause cutting deviation. Therefore, waste passages 12 are provided on the workbench 1 at the rear end of the cutting points on both sides. A waste collection box 8 is placed below the waste passage 12. A waste guiding mechanism 7 is provided in the waste passage 12 to guide the waste into the waste collection box 8. The waste guiding mechanism 7 includes a pair of clamping rollers 71 rotatably connected in the waste passage 12 for clamping the waste and conveying it downward by rotation, a waste collection motor 73 fixedly installed on the side of the workbench 1 with its output shaft connected to one of the clamping rollers 71, and a pair of transmission gears 72 fixedly connected to the ends of the two clamping rollers 71 away from the waste collection motor 73 and meshing with each other. The waste collection motor 73 is connected to an external control system.

[0032] The waste material is inserted between two clamping rollers 71. The output shaft of the waste collection motor 73 drives one of the connected clamping rollers 71 to rotate. Since the ends of the two clamping rollers 71 away from the waste collection motor 73 are connected by a pair of meshing transmission gears 72, according to the principle of gear transmission, when one gear rotates, it will drive the other gear to rotate in the opposite direction. Therefore, when one clamping roller 71 rotates, it will drive the other clamping roller 71 to rotate in the opposite direction through the transmission gear 72. The two clamping rollers 71 rotate relative to each other, forming a clamping effect on the waste material, clamping the waste material in the middle. As the clamping rollers 71 continue to rotate, the waste material is conveyed downward and falls into the waste collection box 8 below through the waste material outlet 12, thereby realizing the automatic collection of waste material. During this period, the external control system makes the speed of the waste collection motor 73 match the conveying speed of the geomembrane. The waste material is automatically conveyed to the waste collection box 8 through the waste material guiding mechanism 7, which greatly reduces manual operation, reduces labor intensity, improves production efficiency, avoids the accumulation of waste material on the workbench 1 and affects the flatness of the geomembrane, and ensures the cutting quality.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
