Description

Technical Field

[0001] The utility model relates to the field of geomembrane production and processing, in particular to a cutting device with good cross-section flatness. Background Technique

[0002] The geomembrane is a geomantic impervious material made of a plastic film as an impervious base material and compounded with a non-woven fabric. The impervious performance of the geomembrane mainly depends on the impervious performance of the plastic film. It is mainly applied to reservoirs, tunnels, landfills and other places. When laying the geomembrane, it is necessary to cut the geomembrane roll, so it is necessary to assist in cutting through a geomembrane cutting device.

[0003] The inventor found the following problems in the prior art during the implementation of the present application:

[0004] In the prior art, the geomembrane is usually only placed on the cutting table for cutting during the cutting process, and the position of the geomembrane itself is not fixed. Therefore, during use, the geomembrane is easily displaced under the pressure of the cutting knife, resulting in an uneven cross-section. Moreover, in the prior art, when cutting the geomembrane, the worker usually pulls the wound geomembrane under the cutting knife by hand. This pulling method easily causes uneven stress on the geomembrane, resulting in deformation and wrinkles, affecting the cutting accuracy.

[0005] Therefore, those skilled in the art provided a cutting device with good cross-section flatness to solve the problems raised in the above background technique. Content of the Utility Model

[0006] The purpose of the utility model is to solve the shortcomings existing in the prior art, and to propose a cutting device with good cross-section flatness, which can make the cross-section of the geomembrane more flat and improve the cutting accuracy of the geomembrane.

[0007] To achieve the above purpose, the utility model provides the following technical solutions:

[0008] A cutting device with good cross-section flatness includes a workbench. Four corners of the lower end surface of the workbench are fixedly provided with supports. The front and rear ends of one side of the center of the upper end surface of the workbench are fixedly provided with support plates. A fixed box is slidably arranged on the opposite sides of the two support plates. A pressing box is slidably arranged on the inner wall of the fixed box. A cutting knife is fixedly arranged at the center of the lower end surface of the pressing box. A stretching mechanism is arranged at the lower end surface of the fixed box. The stretching mechanism includes two stretching plates, two second springs and four rotating plates;

[0009] On the upper end surface of the workbench, a sliding base is slidably arranged on the other side. Inside the inner wall of the sliding base, a clamping block is slidably arranged. At both front and rear ends of the upper end surface of the sliding base, a rebound groove is respectively opened. In both of the two rebound grooves, a fixing mechanism is arranged. Both of the two fixing mechanisms include an inlay block, a dial plate and a third spring. On one side of the workbench, a winding roller is rotatably arranged.

[0010] Further, one ends of the four rotating plates are respectively hinged at the front and rear ends of one side of the upper end surfaces of the two stretching plates, and the other ends of the four rotating plates are respectively hinged at the four corners of the lower end surface of the fixing box. The two second springs are respectively fixedly arranged at the front and rear ends of the opposite sides of the two stretching plates close to each other.

[0011] Further, the two dial plates are respectively slidably arranged inside the two rebound grooves. The two inlay blocks are respectively fixedly arranged at the centers of the opposite sides of the two dial plates. The two third springs are respectively fixedly arranged at the centers of the opposite sides of the two dial plates.

[0012] Further, at the centers of both sides of the inner wall of the fixing box, a clamping groove is respectively opened. At the bottom end surfaces of the inner walls of the two clamping grooves, five first springs are respectively fixedly arranged. At the upper ends of the centers of both sides of the pressing box, a clamping block is respectively fixedly arranged. The two clamping blocks are respectively slidably clamped inside the two clamping grooves and are respectively fixedly connected with the five first springs in the two clamping grooves.

[0013] Further, at the centers of the opposite surfaces of the two support plates, a slide rail is respectively fixedly arranged. At the centers of the front and rear end surfaces of the outer wall of the fixing box, a slider is respectively fixedly arranged. The two sliders are respectively slidably arranged inside the two slide rails.

[0014] Further, at the centers of the front and rear end surfaces of the inner wall of the sliding base, a clamping groove is respectively opened. At the centers of the front and rear end surfaces of the clamping block, a clamping block is respectively fixedly arranged. At the upper ends of the opposite surfaces of the two clamping blocks, an inlay groove is respectively opened. The two clamping blocks are respectively slidably arranged inside the two clamping grooves. The two inlay blocks are respectively embedded inside the two inlay grooves.

[0015] Further, at the front and rear ends of one side of the upper end surface of the workbench, a fixing block is respectively fixedly arranged. Of the four fixing blocks, two fixing blocks located at the front and rear ends respectively have a slide rod fixedly arranged on the opposite side. The two slide rods respectively penetrate through the lower ends of one side of the sliding base close to the front and rear ends.

[0016] The utility model has the following beneficial effects:

[0017] 1. A cutting device with good cross-sectional flatness proposed by the present utility model. When pressing down the pressing box, the fixed box moves downward along the slide rail. After the two stretching plates contact the geomembrane, continue to press down the pressing box, so that the pressing box moves downward and presses downward through the first spring, causing the four rotating plates to rotate, thereby pushing the two stretching plates to move to both sides, and flattening the geomembrane through the friction force of the stretching plates, facilitating the cutting of the geomembrane by the cutting knife at the center of the lower end face of the pressing box, and improving the flatness of the cross-section.

[0018] 2. A cutting device with good cross-sectional flatness proposed by the present utility model. Place one end of the geomembrane on the winding roller on the inner wall of the sliding base, and then press down the clamping block. The insertion block is embedded in the insertion groove under the elastic force of the third spring to fix the position of the clamping block, so that the clamping block and the sliding base can clamp and fix the geomembrane. Then slide through the slide bar and use the scale bar on the slide bar to position the cutting length of the geomembrane, avoiding the problems of deformation and wrinkles of the geomembrane caused by pulling the geomembrane by hand in the prior art, resulting in low cutting accuracy of the geomembrane.

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0026] Referring to Figures 1 to 4 , an embodiment provided by the present invention is as follows:

[0027] A cutting device with good cross-sectional flatness includes a workbench 1. At the four corners near the lower end surface of the workbench 1, brackets 2 are fixedly arranged. At the front and rear ends on one side of the center of the upper end surface of the workbench 1, support plates 4 are fixedly arranged. A fixed box 8 is slidably arranged on the opposite surfaces of the two support plates 4. A pressing box 6 is slidably arranged on the inner wall of the fixed box 8. At the center of the lower end surface of the pressing box 6, a cutting knife 13 is fixedly arranged. A stretching mechanism 12 is arranged on the lower end surface of the fixed box 8. The stretching mechanism 12 includes two stretching plates 1201, two second springs 1202, and four rotating plates 1203.

[0028] On the other side of the upper end surface of the workbench 1, a sliding base 3 is slidably arranged. A clamping block 9 is slidably arranged on the inner wall of the sliding base 3. Rebound grooves 18 are respectively opened at the front and rear ends near the upper end surface of the sliding base 3. Fixed mechanisms 19 are arranged in the two rebound grooves 18. Both fixed mechanisms 19 include an inlay block 1901, a dial 1902, and a third spring 1903. A winding roller 5 is rotatably arranged on one side of the workbench 1.

[0029] Specifically, through the slide rail 7, the fixed box 8 can be slidably arranged on the opposite sides of the two support plates 4. By pressing down the pressing box 6, the pressing box 6 can drive the fixed box 8 to move downward, and the stretching mechanism 12 is used to flatten the geomembrane around the cutting point. Continuing to press down the pressing box 6 enables the cutting knife 13 to cut the flattened geomembrane, which can make the cross-section more flat. The geomembrane can be clamped by the clamping block 9, and the position of the clamping block 9 is fixed by the fixed mechanism 19, and then the sliding base 3 is pulled to adjust the cutting position, which can prevent the geomembrane from deforming and wrinkling during the pulling process, thereby improving the cutting accuracy of the geomembrane.

[0030] Referring to Figure 2 , one ends of the four rotating plates 1203 are respectively hinged to the front and rear ends on one side of the upper end surfaces of the two stretching plates 1201, and the other ends of the four rotating plates 1203 are respectively hinged to the four corners of the lower end surface of the fixed box 8. The two second springs 1202 are respectively fixedly arranged at the front and rear ends near the opposite sides of the two stretching plates 1201.

[0031] Specifically, when the fixed box 8 applies downward pressure and the two stretching plates 1201 are in contact with the geomembrane, the two rotating plates 1203 rotate under the pressure of the fixed box 8, thereby pushing the two stretching plates 1201 to move to both sides, and the geomembrane is stretched flat through the friction between the two stretching plates 1201 and the geomembrane.

[0032] Reference Figure 3 , Figure 4 The two plates 1902 are slidably disposed inside the two rebound grooves 18, respectively. The two inserts 1901 are fixedly disposed at the centers of the opposite sides of the two plates 1902, respectively. The two No. 3 springs 1903 are fixedly disposed at the centers of the separated sides of the two plates 1902, respectively.

[0033] Specifically, the position of the block 1901 can be controlled by the shift plate 1902 and the No. 3 spring 1903. When the block 1901 and the embedding groove 22 are located on the same horizontal line, the block 1901 can be embedded in the embedding groove 22 under the action of the No. 3 spring 1903, and the block 1901 can be driven out of the embedding groove 22 by shifting the shift plate 1902.

[0034] Reference Figure 2 A clamping groove 15 is provided at the center of both sides of the inner wall of the fixed box 8, and five No. 1 springs 16 are fixedly set on the bottom end surfaces of the inner walls of the two clamping grooves 15. A clamping block 14 is fixedly set at the upper end of the center of both sides of the pressing box 6. The two clamping blocks 14 are respectively slidably clamped in the two clamping grooves 15 and are respectively fixedly connected with the five No. 1 springs 16 in the two clamping grooves 15.

[0035] Specifically, the spring can make the No. 1 spring 16 play a certain buffering role when the pressing box 6 is pressed downward, thereby preventing the stretching plate 1201 from moving quickly to both sides due to excessive force applied during pressing, and the friction between the stretching plate 1201 and the geomembrane from damaging the surface of the geomembrane, affecting subsequent use.

[0036] Reference Figure 1 and Figure 2 A slide rail 7 is fixedly provided at the center of each opposite side of the two support plates 4 , and a slider 17 is fixedly provided at the center of each front and rear end surface of the outer wall of the fixed box 8 , and the two sliders 17 are slidably provided inside the two slide rails 7 , respectively.

[0037] Specifically, it is convenient to slide and adjust the position of the fixing box 8 so that the fixing box 8 can be moved up and down to cut the geomembrane using the cutting knife 13 .

[0038] Reference Figure 3 , Figure 4, clamping grooves 20 are formed at the centers of the front and rear end faces of the inner wall of the sliding base 3, clamping blocks 21 are fixedly arranged at the centers of the front and rear end faces of the clamping block 9, embedding grooves 22 are formed at the upper ends of the opposite sides of the two clamping blocks 21, the two clamping blocks 21 are respectively slidably arranged inside the two clamping grooves 20, and the two embedding blocks 1901 are respectively embedded inside the two embedding grooves 22.

[0039] Specifically, the position of the clamping block 9 can be restricted by the clamping block 21 and the clamping groove 20 to prevent the clamping block 9 from sliding to both sides during use. The embedding block 1901 and the embedding groove 22 can fix the vertical position of the clamping block 9 to prevent the clamping block 9 from slipping off and affecting the fixing effect on the geomembrane.

[0040] Refer to Figure 1 , fixing blocks 11 are fixedly arranged at the front and rear ends of one side of the upper end face of the workbench 1. Two of the four fixing blocks 11 located at the front and rear ends respectively have sliding rods 10 fixedly arranged on their opposite sides. The two sliding rods 10 respectively penetrate through the lower ends of one side of the sliding base 3 near the front and rear ends, and scale bars are fixedly arranged on the outer walls of the two sliding rods 10.

[0041] Specifically, after the geomembrane is clamped and fixed by the sliding base 3 and the clamping block 9, the sliding base 3 is slid to one side along the sliding rod 10, and the position of the sliding base 3 is conveniently adjusted through the scale bar on the sliding rod 10, which can improve the cutting accuracy of the geomembrane.

[0042] Working principle: One end of the geomembrane wound around the winding roller 5 is pulled out through the gap between the stretching mechanism 12 and the workbench 1 and placed on the inner wall of the sliding base 3. Then, the clamping block 9 is pressed downward through the clamping groove 20 and the clamping block 21. When the embedding groove 22 and the embedding block 1901 are on the same horizontal line, the embedding block 1901 is embedded inside the embedding groove 22 under the action of the third spring 1903 to restrict the position of the clamping block 9, thereby clamping and fixing one end of the geomembrane. Then, the sliding base 3 is moved to one side through the sliding rod 10, and the cutting position of the geomembrane is positioned through the scale bar on the sliding rod 10, which can effectively prevent the deformed and wrinkled end of the geomembrane from being pulled during cutting due to uneven force, affecting the accuracy during cutting. Then, the pressing box 6 is pressed to drive the fixing box 8 and the stretching mechanism 12 to move downward. When the two stretching plates 1201 contact the geomembrane, the fixing box 8 is continuously pressed through the pressing box 6, so that the four rotating plates 1203 rotate, thereby pushing the two stretching plates 1201 to move to both sides, enabling the two stretching plates 1201 to flatten the geomembrane. Then, the geomembrane is cut by the cutting knife 13, thereby improving the flatness of the cross-section of the geomembrane.

[0043] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
