[0003] The above-mentioned device is intended to solve the problem in the prior art that the geomembrane roll is not fixed when the commonly used hydraulic guillotine for geomembrane cutting is in use, and the geomembrane roll is subjected to the pressure of the guillotine, which easily causes the displacement of the geomembrane roll, thereby resulting in low cutting accuracy of the geomembrane roll. However, when the device is in use, the pressure block and the stop block for fixing the geomembrane roll are in a fixed form. When it comes to geomembranes of different thicknesses, the two sides of the geomembrane cannot be fitted and fixed. Therefore, when using this device, problems such as tilting and deviation may still occur during cutting. Utility Model Content

[0004] The technical problem to be solved by the utility model is as follows: when cutting, the geomembrane may be tilted and deviated due to the pressure of the cutting knife.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] An extrusion shaft 206 is fixedly mounted on the end surface of the clamping jaw 204 away from the gasket 207. The extrusion shaft 206 passes through the arc groove 208 and the side wall is slidably connected to the arc groove 208. When the arc groove 208 rotates with the rotating disk 205, the extrusion shaft 206 is pushed by the arc groove 208 and thus displaced.

[0025] A connecting rod 209 is fixedly installed at one end of the bottom of the turntable 205, and a cam 210 is rotatably connected to the bottom of the back of the connecting rod 209. One end of the cam 210 passes through the connecting rod 209 and is fixedly installed with a knob 1. The support plate 201 is located below the turntable 205 and is provided with a groove 211. The top and bottom of the inner wall of the groove 211 are fixedly installed with a gasket 212. The outer wall of the gasket 212 is movably connected to the cam 210. A threaded sleeve 202 is fixedly installed in the middle of the bottom of the support plate 201. The material of the gasket 212 is rubber. The purpose is to deform and fix the two sides of the cam 210 when it contacts the cam 210. In addition, it can increase the friction with the cam 210 to prevent movement.

[0026] The adjustment mechanism 1 includes a device base 101, and both sides of the inner wall of the device base 101 are rotatably connected with threaded rods 102, the outer ends of the threaded rods 102 pass through the device base 101 and are fixedly installed with knobs 2, the outer wall of the threaded rod 102 on one side is threadedly sleeved with a threaded sleeve 202, the inner wall of the device base 101 is slidably connected with a support plate 201, and the support plate 201 simply supports the bottom of the geomembrane, so that the geomembrane roll is conveniently fixed by the clamping claws 204;

[0027] The outer wall thread sleeve of the threaded rod 102 on the other side is provided with a threaded sleeve 105, and a limit baffle 106 is fixedly installed on the top of the threaded sleeve 105. The bottom side wall of the limit baffle 106 is slidably connected to the device base 101, and the limit baffle 106 clamps and fixes the other end of the geomembrane roll;

[0028] A limiting groove 103 is provided on the inner wall of the device base 101 and in the middle of the threaded rod 102. A spring 104 is fixedly installed on the top of the device base 101 located outside the limiting groove 103. A lower support plate 108 is sleeved on the inner wall of the spring 104. The middle bottom of the lower support plate 108 passes through the spring 104 and is slidably connected to the limiting groove 103. A cutting knife 107 is fixedly installed in the middle of the back of the device base 101. The cutting knife 107 is a shearing knife in the prior art. The geomembrane roll can be cut by pushing the blade down.

[0029] The working principle of this utility model:

[0030] First, place the geomembrane roll on the top of the lower support plate 108, then press the geomembrane roll downward, so that one end of the geomembrane contacts the support plate 201, and ensure that one end of the geomembrane roll is located in the middle of the inner side of the clamp 204. At this time, turn the turntable 205. When the turntable 205 rotates inside the support plate 201, the arc groove 208 squeezes and pushes the extrusion shaft 206 to move. The extrusion shaft 206 is fixed to the clamp 204, and the clamp 204 is limited inside the limit frame 203. When the arc groove 208 pushes the extrusion shaft 206, the clamp 204 moves linearly in the limit frame, and the distance between the clamps 204 changes.

[0031] Secondly, the clamping jaws 204 are contracted so that the gasket 1 207 contacts the geomembrane and limits the side of the geomembrane. At this time, the knob 1 is turned to control the cam 210 to rotate inside the groove 211. The cam 210 contacts and squeezes the gasket 212. The gasket 212 is deformed and fixes the two ends of the cam 210, thereby making the connecting rod 209 unable to rotate, the rotating disk 205 unable to rotate, and the spacing of the clamping jaws 204 is fixed;

[0032] In addition, rotating the knob 2 on one side causes the threaded rod 102 to rotate and drive the limit baffle 106 and the other end of the geomembrane to limit the position through the threaded sleeve 105. At this time, rotating the knob 2 at the same time can change the overall position of the geomembrane roll, making it convenient for the cutting knife 107 to cut different parts.

[0033] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
