DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Please refer to Figures 1-4, the utility model provides an adjustable cutting device for geomembrane processing, including a working table 1. At the top of the working table 1, there is a U-shaped moving seat 2. At both ends of the top surface of the working table 1 located at the bottom of the moving seat 2, openings 3 are penetrated. Inside the openings 3, sliding seats 4 are inserted. The top of the sliding seat 4 is fixed to the bottom surface of the moving seat 2. At the middle position of one of the sliding seats 4, a limiting shaft 6 is penetrated and inserted. Both sides of the limiting shaft 6 are fixed to the inner wall of the sliding seat 4. At the middle position of the other sliding seat 4, a first threaded rod 5 is penetrated and threadedly connected. Both sides of the first threaded rod 5 are rotatably connected to the inner wall of the sliding seat 4. One end surface of the working table 1 is rotatably connected with a rotating rod 7. One end of the rotating rod 7 extends to the inner cavity position of the adjacent sliding seat 4. A first bevel gear 8 is fixedly sleeved on the outer peripheral surface of the rotating rod 7. A second bevel gear 9 is fixedly sleeved on the outer peripheral surface of the first threaded rod 5 near the first bevel gear 8. The first bevel gear 8 and the second bevel gear 9 are meshed with each other. At the bottom of the inner surface of the moving seat 2, there is a cutting seat 10. At the bottom of the cutting seat 10, there is a support seat 11. A cutting edge 12 is provided on the surface of the support seat 11. By rotating the rotating rod 7, the position of the moving seat 2 in the horizontal position can be adjusted, so as to adjust the position of the support seat 11 in the horizontal direction of the geomembrane, so as to facilitate adjusting the positions of the support seat 11 and the cutting seat 10 when there is an error in the subsequent geomembrane conveying to ensure accurate positioning of the required cutting part and ensure the flatness of the cutting opening.

[0022] Further, as Figure 1 , Figure 2 and Figure 3 shown, it is worth specifically explaining that on both sides of the inner surface of the opening 3, rod grooves 13 are provided. Inside the rod grooves 13, sliding sleeves 14 are inserted. The mutually approaching ends of the sliding sleeves 14 are fixed to the surface of the support seat 11. At the middle position of one of the sliding sleeves 14, a second threaded rod 15 is penetrated and threadedly connected. The bottom of the second threaded rod 15 is rotatably connected to the inner wall of the rod groove 13. The top of the second threaded rod 15 passes through the opening 3 and extends to the outside of the opening 3. Since the sliding sleeve 14 can limit the movement track of the support seat 11, when the second threaded rod 15 is rotated, the support seat 11 can move in the vertical direction under the cooperation of the internal thread structure on the inner wall of one of the sliding sleeves 14 and the external thread structure on the outer peripheral surface of the second threaded rod 15.

[0023] Further, as Figure 3As shown, it is worth specifically stating that two shaft grooves 16 are formed at the bottom of the inner surface of the moving seat 2. An embedded shaft 17 is fixed inside the shaft groove 16. A shaft sleeve 18 is slidably sleeved on the outer peripheral surface of the embedded shaft 17. The bottom of the shaft sleeve 18 is hinged with a connecting rod 19. The bottom of the connecting rod 19 is hinged with the top surface of the cutting seat 10. At the middle position of the top surface of the opening 3, a hydraulic cylinder 20 is fixed. The output end of the hydraulic cylinder 20 passes through the moving seat 2 and is fixed with the top surface of the cutting seat 10. By starting the hydraulic cylinder 20, the cutting seat 10 can move in the vertical direction, so that the connecting rod 19 can change its angle, enabling the shaft sleeve 18 to slide along the outer peripheral surface of the embedded shaft 17 in the inner cavity of the adjacent shaft groove 16, thereby playing a role in limiting the movement trajectory of the cutting seat 10 to ensure the stability of the movement of the cutting seat 10.

[0024] Furthermore, as Figure 2 shown in Figure 3 it is worth specifically stating that two clamping frames 22 are arranged outside the moving seat 2. Two positioning shafts 23 are fixed on the surfaces at both ends of the workbench 1. The clamping frames 22 are slidably connected with the plurality of positioning shafts 23. On one side of the top surface of the moving seat 2, a motor 21 is fixed. The output end of the motor 21 is fixed with a third threaded rod 24. The outer peripheral surface of the third threaded rod 24 is threadedly connected with one of the clamping frames 22. The bottom of the third threaded rod 24 is rotatably connected with the other clamping frame 22. One of the clamping frames 22 is fixed with the surface of the support seat 11. Since the positioning shafts 23 can play a role in limiting the movement trajectory of the clamping frames 22, when the motor 21 is started, the third threaded rod 24 can rotate. Thus, under the cooperation of the internal thread structure on the inner wall of one of the clamping frames 22 and the external thread structure on the outer peripheral surface of the third threaded rod 24, the distance between the two clamping frames 22 can change, thereby being able to position the geomembrane during cutting.

[0025] The present solution has the following working process: During actual use, when the user needs to cut the geomembrane, first, the conveying roller at the rear end passes the geomembrane through the middle position between the cutting seat 10 and the support seat 11. Adjust the position of the moving seat 2 in the horizontal direction according to the state of the geomembrane during conveyance, so that the cutting seat 10 can accurately cut the position where the geomembrane needs to be cut. By rotating the rotating rod 7, the first bevel gear 8 can be rotated, so that the first threaded rod 5 can be rotated under the meshing action between the first bevel gear 8 and the second bevel gear 9. Since the inner cavity of the opening 3 and the limiting shaft 6 can limit the sliding seat 4, the moving seat 2 can move horizontally under the cooperation between the internal thread structure on the inner wall of one of the sliding seats 4 and the external thread structure on the outer peripheral surface of the first threaded rod 5, so that the moving seat 2 can move to the top position of the position where the geomembrane needs to be cut. Since the sliding sleeve 14 can limit the movement trajectory of the support seat 11, then when the second threaded rod 15 is rotated, the support seat 11 can move vertically under the cooperation between the internal thread structure on the inner wall of one of the sliding sleeves 14 and the external thread structure on the outer peripheral surface of the second threaded rod 15, so that the support seat 11 can stably support the bottom of the geomembrane. By starting the motor 21, the third threaded rod 24 can make a rotational movement, so that the distance between the two clamping frames 22 can change under the cooperation between the internal thread structure on the inner wall of one of the clamping frames 22 and the external thread structure on the outer peripheral surface of the third threaded rod 24, so that the geomembrane being cut can be clamped and positioned. By starting the hydraulic cylinder 20, the cutting seat 10 can move vertically, so that the connecting rod 19 can change its angle and the bushing 18 can slide along the outer peripheral surface of the embedded shaft 17 in the inner cavity of the adjacent shaft groove 16, so that the movement trajectory of the cutting seat 10 can be limited to ensure the stability of the movement of the cutting seat 10, so that the bottom of the cutting seat 10 is embedded inside the cutting edge 12 to complete the cutting operation of the geomembrane.

[0026] According to the above working process, it can be known that: By rotating the rotating rod 7, the position of the moving seat 2 in the horizontal position can be adjusted, and by rotating the second threaded rod 15, the height of the support seat 11 can be adjusted. Thus, by adjusting the horizontal and vertical positions of the support seat 11 for supporting the geomembrane, it is convenient to adjust the positions of the support seat 11 and the cutting seat 10 when there are errors in the conveyance of the geomembrane at the rear end to ensure accurate positioning of the part to be cut and the flatness of the cutting opening, thereby improving the practicability of the device. By starting the motor 21, the distance between the two support seats 11 can be adjusted, so that the two support seats 11 can limit the geomembrane before cutting, thereby further ensuring the accuracy of cutting the geomembrane and further improving the practicability of the device.

[0027] Furthermore, as Figure 3 shown, it is worth specifically stating that a limiting rod 25 is inserted through the middle position of another sliding sleeve 14. The upper and lower ends of the limiting rod 25 are fixed to the inner wall of the adjacent rod slot 13. Due to the setting of the limiting rod 25, it can play a limiting role on the other sliding sleeve 14, thereby further improving the movement stability of the support base 11.

[0028] In summary: By rotating the rotating rod 7, the position of the moving seat 2 in the horizontal position can be adjusted. By rotating the second threaded rod 15, the height of the support base 11 can be adjusted. Thus, by adjusting the horizontal and vertical positions of the support base 11 for supporting the geomembrane, it is convenient to adjust the positions of the support base 11 and the cutting seat 10 when there is an error in the conveyance of the geomembrane at the rear end to ensure accurate positioning of the required cutting part and ensure the flatness of the cutting opening, thereby improving the practicality of the device. By starting the motor 21, the distance between the two support bases 11 can be adjusted, so that the two support bases 11 can limit the geomembrane before cutting, thereby further ensuring the accuracy of the geomembrane cutting and further improving the practicality of the device. Due to the setting of the limiting rod 25, it can play a limiting role on the other sliding sleeve 14, thereby further improving the movement stability of the support base 11.

[0029] The hydraulic cylinder 20 and the motor 21 can be purchased on the market. The hydraulic cylinder 20 and the motor 21 are equipped with power supplies, which are mature technologies in this field and have been fully disclosed, so they will not be repeated in the specification.
