Description

Technical Field

[0001] The utility model relates to the technical field of geomembrane processing, in particular to a cutting device for geomembrane processing. Background Art

[0002] Geomembrane is a geotechnical anti-seepage material made of plastic film as the anti-seepage base material and composited with non-woven fabrics. The anti-seepage performance of the new material geomembrane mainly depends on the anti-seepage performance of the plastic film. The plastic films used for anti-seepage applications at home and abroad are mainly polyvinyl chloride and polyethylene. ECB is also designed for use in tunnel applications. They are a kind of polymer chemical flexible material with low specific gravity, strong extensibility, high adaptability to deformation, corrosion resistance, low temperature resistance, and good anti-freeze performance. When manually cutting geomembrane, the geomembrane cannot be well fixed, which easily causes uneven cutting edges. For this reason, the Chinese utility model patent with announcement number CN220128887U discloses a multi-station cutting device for geomembrane processing. When it works, the cylinder is first started to push the sliding rod and the cutter to smoothly descend under the action of the limit groove. At the same time, the connecting rod and the fixed rod are lowered. When the bottom end of the pressure rod contacts the geomembrane, the fixed column slides in the sliding hole on the fixed rod. Under the limit of the limit block, the fixed column cannot be separated from the action of the fixed rod. Under the action of the spring on the fixed column, the pressure rod is pressed against the geomembrane to fix it. Then, when the cutter descends and contacts the geomembrane, the cutting is completed, realizing the fixing and cutting of the geomembrane in one, and improving the flatness of the cut edge. However, the cutter of the device is a downward pressure cutting method, and the blade penetrates the width of the geomembrane, which can only cut the geomembrane, and the position and size of the cut edge cannot be flexibly selected.

The bottom of the lifting plate 13 is provided with a pair of second support plates 12 parallel to the first support plates 18, and a screw 25 parallel to the support shaft 20 is rotatably provided between the pair of second support plates 12. The two ends of the screw 25 are rotatably connected to the pair of second support plates 12 through a bearing structure, and a moving block 4 is movably provided on the screw 25. A threaded hole is provided in the middle of the moving block 4. The screw 25 is inserted in the threaded hole and connected to the moving block 4 through a threaded structure. The moving block 4 and the screw 25 are equivalent to the screw nut of the screw, and the bottom of the moving block 4 is provided with a blade 3 axially parallel to the support shaft 20, and the blade 3 is vertically arranged. The blade 3 is moved along the first limiting groove 26 to cut and cut the geomembrane covered on the support shaft 20.

[0026] The method of using the cutting device for geomembrane processing provided by the present technical solution is as follows: first, the geomembrane is passed through and covered on the support shaft 20, so that the position to be cut corresponds to the first groove, and then the geomembrane on both sides of the support shaft 20 is tightened so that the contact part of the geomembrane and the surface of the support shaft 20 is attached and the first limiting groove 26 is covered to fix the geomembrane, and then the screw 25 is rotated to directly or indirectly drive the blade 3 to move. After reaching the position to be cut, the lifting plate 13 is moved down to directly or indirectly drive the blade 3 to drop until the tip passes through the geomembrane and then inserts into the first limiting groove 26, and then the screw 25 is rotated to move the blade 3 along the first limiting groove 26 to cut the geomembrane until the cutting opening meets the required size, and the lifting plate 13 is moved up to indirectly drive the blade 3 to move up and separate from the geomembrane; then the geomembrane is moved to the next position to be cut corresponding to the first limiting groove 26, and the above cutting process is repeated.

[0027] The utility model includes at least the following beneficial effects: a pair of vertical first support plates 18 are arranged on the support platform 24, a horizontal support shaft 20 is arranged between the pair of first support plates 18, a horizontal lifting plate 13 is arranged to be lifted just above the support shaft 20, a pair of second support plates 12 parallel to the first support plate 18 are arranged at the bottom of the lifting plate 13, a screw 25 parallel to the support shaft 20 is arranged to rotate between the pair of second support plates 12, a moving block 4 is screwed on the screw 25, a blade 3 parallel to the support shaft 20 and arranged vertically is provided at the bottom of the moving block 4, a first limiting groove 26 extending along its length direction and opening upward and located just below the blade 3 is provided on the support shaft 20, a pair of first limiting plates 14 perpendicular to them is also provided between the pair of second support plates 12, the moving block 4 is located between the pair of first limiting plates 14 and is in sliding contact with each first limiting plate 14; when in use, the geomembrane is first passed through and covered on the support shaft 20 so that the position to be cut corresponds to the first groove, and then The geomembrane is fixed, and the screw 25 is rotated to indirectly drive the blade 3 to move horizontally. After it reaches the position to be cut, the lifting plate 13 is moved down to indirectly drive the blade 3 to descend until the tip passes through the geomembrane and inserts into the first limiting groove 26. The screw 25 is rotated again to make the blade 3 move along the first limiting groove 26 to cut the geomembrane until the cutting opening meets the required size. The lifting plate 13 is moved up to indirectly drive the blade 3 to move up and separate from the geomembrane to complete one cutting. During use, the blade 3 can be lifted or moved horizontally multiple times to select different positions of the geomembrane for cutting according to the position to be cut, and the horizontal movement position distance is controllable, and incisions of different sizes can also be cut. The cutting position and size can be flexibly selected, and the scope of application is wider; the two ends of the support shaft 20 are respectively fixedly connected to a pair of first support plates 18, so that the support shaft 20 supports the geomembrane more stably; the tip of the blade 3 can be inserted into the first limiting groove 26 and move along the first limiting groove 26, which can prevent the blade 3 from colliding and rubbing with the support shaft 20 during the cutting process of the geomembrane and being damaged.

[0028] In another technical solution, Figure 1 、 Figure 2 As shown in the figure, in the cutting device for processing geomembrane, the blade 3 is an isosceles triangle with the top angle facing downward, which is convenient for cutting the middle part of the geomembrane.

[0029] In another technical solution, Figure 1 、 Figure 2As shown, in the cutting device for geomembrane processing, a pair of first support plates 18 are provided with horizontal first support plates 6 on the opposite surfaces thereof, and the first support plates 18 are also provided with movable holes located above the first support plates 6, and horizontal slots 9 corresponding to the movable holes are provided on the opposite surfaces of the pair of first support plates 18, and second support plates 7 are inserted into the corresponding slots 9 and movable holes. The lifting plates 13 are placed on the pair of second support plates 7, and the distance between the first support plate 6 and the second support plate 7 is the same as the thickness of the lifting plates 13. A pair of vertical second limit plates 10 are provided on the opposite surfaces of the pair of first support plates 18, and the ends of the lifting plates 13 are slidably arranged between their corresponding pairs of second limit plates 10. The two ends of the lifting plate 13 are respectively located between the corresponding pair of second limit plates 10 and placed on the corresponding second supporting plates 7. The second supporting plates 7 support the lifting plate 13. At this time, the position of the blade 3 is higher than the support shaft 20, so that the geomembrane can pass through between the blade 3 and the support shaft 20 to adjust its position. When lifting and adjusting the lifting plate 13, you can first hold or pull the lifting plate 13 with your hands or tools to keep it stationary, and at the same time pull the second supporting plate 7 from the slot 9 side of the first support plate 18 away from the lifting plate 13 to disengage the second supporting plate 7 from the moving hole. Then slowly lower the lifting plate 13 so that the lifting plate 13 moves down along the second limit plate 10 until the lifting plate 13 falls on the first supporting plate 6, and then push the second supporting plate 7 so that it is inserted into the moving hole and tangent to the top surface of the lifting plate 13 to position the lifting plate 13 to prevent it from moving up and down at will, and then operate the screw 25 and the blade 3 to make the blade 3 move and cut more stably; a plurality of handle rings 11 can be provided on the top of the lifting plate 13, preferably two, distributed on the lifting plate 13 near its end, so as to facilitate hand holding and position the lifting plate 13.

[0030] In another technical solution, Figure 1 As shown, in the geomembrane processing cutting device, a vertical third limit plate 8 is provided at the end of the second support plate 7 located on the back side of the pair of first support plates 18. This prevents the second support plate 7 from moving too far toward the lifting plate 13 and fully inserting into the slot 9, and facilitates the pushing and pulling of the second support plate 7.

The rotation of the unwinding roller 2 drives the limiting ring 17 to rotate and slide within the limiting groove 16. The limiting groove 16 and the limiting ring 17 cooperate to prevent the unwinding roller 2 from moving arbitrarily in the axial direction.

[0033] In another technical solution, Figure 1 、 Figure 2 As shown, in the cutting device for geomembrane processing, a pair of support blocks 23 are further provided on the support platform 24, and a second rotating shaft 22 is rotatably provided on the pair of support blocks 23. The position of the second rotating shaft 22 is lower than the support shaft 20, and the unwinding roller 2 is located on both sides of the support shaft 20 respectively. The two ends of the second rotating shaft 22 are connected to the corresponding support blocks 23 for rotation through a bearing structure, and one end is connected to the output shaft of the second motor 19 located on the support platform 24 and is driven to rotate by the second motor 19; when in use, one end of the geomembrane starts from the unwinding roller 2, passes through the top of the support shaft 20, and is connected to the second rotating shaft 22. Then, the second rotating shaft 22 is rotated to adjust the cutting position of the geomembrane in length until the cutting position is located above the first groove and covers it, the rotation of the second rotating shaft 22 is stopped, and the position of the blade 3 is adjusted to cut the geomembrane; if the geomembrane on the support shaft 20 becomes loose during the process of adjusting the position of the geomembrane, the second rotating shaft 22 or the unwinding roller 2 can be rotated in the opposite direction appropriately until the contact surface between the geomembrane and the support shaft 20 is covered without warping or wrinkling, thereby preventing the cutting edge of the blade 3 from being incomplete.

[0034] In another technical solution, Figure 3 As shown, in the cutting device for geomembrane processing, a positioning groove 28 parallel to the axis thereof is provided on the second rotating shaft 22, and a plurality of elastic positioning blocks 29 are inserted into the positioning groove 28. Preferably, there are three positioning blocks 29, which are evenly distributed in the length direction of the positioning groove 28. When the second rotating shaft 22 and the geomembrane need to be connected, the positioning block 29 can be first removed from the positioning groove 28, and then part of the geomembrane can be inserted into the positioning groove 28. Then, the positioning block 29 can be inserted into the positioning groove 28, and the geomembrane can be clamped between the positioning block 29 and the inner wall of the positioning groove 28. The geomembrane is positioned and easy to install and remove.

[0035] In another technical solution, Figure 1 、 Figure 2As shown, in the cutting device for geomembrane processing, a first rotating shaft 21 is provided below the support shaft 20 and is parallel thereto. Both ends of the first rotating shaft 21 are rotatably connected to a pair of first support plates 18. The geomembrane starts from the unwinding roller 2 and passes under the first rotating shaft 21, then passes between the first rotating shaft 21 and the support shaft 20, then passes over the support shaft 20, and finally extends to the second rotating shaft 22 and is connected to the second rotating shaft 22. The first rotating shaft 21 changes the stretching direction of the geomembrane to assist the geomembrane in further stretching.
