Description

Technical Field

[0001] This utility model belongs to the field of composite geomembrane production technology, and in particular relates to a composite device for producing composite geomembranes. Background Technology

[0002] Composite geomembranes are widely used in canal seepage prevention projects. The extensive application and effectiveness of geosynthetics in civil engineering, especially in flood control and disaster relief projects, have attracted great attention from engineering technicians. Composite geomembranes are impermeable materials made of geotextiles and geomembranes. They are mainly used for seepage prevention. Composite geomembranes are divided into one-layer geotextile and one-layer geomembrane and two-layer geotextile and one-layer geomembrane, with a width of 4-6m and a weight of 200-1500g / m2. They have high physical and mechanical properties such as tensile strength, tear resistance, and puncture resistance, and can meet the needs of civil engineering projects such as water conservancy, municipal engineering, construction, transportation, subway, and tunnels.

[0003] However, some composite devices used for producing composite geomembranes have relatively simple structures. They often use hydraulic cylinders to directly press down and extrude geotextiles and geomembranes to form a composite. Since the hydraulic cylinder is designed and adjusted to have a constant pressure, unexpected situations may occur when pressing the membrane. When geotextiles or geomembranes of different thicknesses are fed into the device, the constant pressure may cause damage to the device. Utility Model Content

[0004] The purpose of this utility model is to provide a composite device for producing composite geomembranes. By setting up a composite mechanism, the elasticity of the spring is used to buffer the constant downward pressure of the hydraulic cylinder and the pressure roller. This helps to stabilize the pressure fluctuations caused by the feeding of composite membranes of different thicknesses into the device in case of unexpected situations during the membrane pressing process. This solves the problem of device damage when geotextiles or geomembranes of different thicknesses are fed into the device in case of unexpected situations.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a composite device for producing composite geomembranes, including a shell, on which an extrusion mechanism and a film conveying mechanism are provided;

[0007] The composite mechanism includes a pressing component and a buffer component. The pressing component includes a fixed block fixedly connected to the top surface of the outer shell. A hydraulic cylinder is fixedly connected to the inner wall of the fixed block. A pressing plate is fixedly connected to the output end of the hydraulic cylinder.

The outer wall of each of the guide rods is slidably connected to the inner wall of the pressing plate.

[0008] Furthermore, the buffer assembly includes several springs that are fixedly connected to the bottom surface of the lower pressure plate, and a slider is fixedly connected to the bottom end of each of the springs.

[0009] Furthermore, each of the pressure rollers has a limiting groove on its inner wall, and each of the limiting grooves has a limiting post rotatably connected to its inner wall. The ends of the limiting posts that are far apart from each other are fixedly connected to the sides of the two connecting plates that are close to each other. The inner walls of the sliders are slidably connected to the outer walls of the guide rods.

[0010] Furthermore, the film conveying mechanism includes a conveying component, a film discharging component, and a reversing component. The conveying component includes a first motor fixedly connected to the left side of the housing. A plurality of first rotating shafts are rotatably connected to the inner wall of the housing. The left end of the first rotating shaft located on the rear side is fixedly connected to the output end of the first motor.

[0014] This utility model has the following beneficial effects:

[0015] 1. By setting up a composite mechanism, the elasticity of the spring is used to buffer the pressure roller that is constantly pressed down by the hydraulic cylinder.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 As shown, this utility model is a composite device for producing composite geomembranes, including a shell 1, on which an extrusion mechanism 2 and a film conveying mechanism 3 are provided;

[0028] The composite mechanism 2 includes a pressing component and a buffer component. The pressing component includes a fixed block 21 fixedly connected to the top surface of the outer shell 1. A hydraulic cylinder 22 is fixedly connected to the inner wall of the fixed block 21. A pressing plate 23 is fixedly connected to the output end of the hydraulic cylinder 22. A plurality of sliding grooves 24 are provided on the inner wall of the outer shell 1. Guide rods 25 are fixedly connected to the inner walls of the plurality of sliding grooves 24. The outer walls of the plurality of guide rods 25 are slidably connected to the inner wall of the pressing plate 23.

[0029] Among them, such as Figure 2 , Figure 3 and Figure 5 As shown, the buffer assembly includes several springs 26 fixedly connected to the bottom surface of the lower pressure plate 23. Each spring 26 has a slider 27 fixedly connected to its bottom end. Two connecting plates 28 are fixedly connected to the sides of the sliders 27 that are close to each other. Several pressure rollers 29 are rotatably connected to the sides of the two connecting plates 28 that are close to each other. Each pressure roller 29 has a limit groove 210 on its inner wall. Each limit groove 210 has a limit post 211 rotatably connected to its inner wall. Each limit post 211 has a section that is far apart from each other and is fixedly connected to the side of the two connecting plates 28 that are close to each other. The inner walls of the sliders 27 are slidably connected to the outer wall of the guide rod 25.

[0030] By setting up the composite mechanism 2, the elasticity of the spring 26 is used to buffer the pressure roller 29 that is constantly pressed down by the hydraulic cylinder 22. This helps to stabilize the pressure fluctuations caused by the delivery of composite films of different thicknesses into the device in case of unexpected situations during film pressing. To a certain extent, this avoids the possibility of damage to the composite film or machine due to constant pressure caused by unexpected situations, thus ensuring the stable operation of the device.

[0031] Among them, such as Figure 2 , Figure 3 and Figure 4As shown, the film conveying mechanism 3 includes a conveying assembly, a film discharging assembly, and a reversing assembly. The conveying assembly includes a first motor 31 fixedly connected to the left side of the outer casing 1. A plurality of first rotating shafts 32 are rotatably connected to the inner wall of the outer casing 1. The left end of the first rotating shafts 32 located on the rear side is fixedly connected to the output end of the first motor 31. The right ends of the plurality of first rotating shafts 32 extend to the right side of the outer casing 1 and are fixedly connected to first gears 33. A chain belt 34 is sleeved between the plurality of first gears 33. The film discharging assembly includes rotating rollers 35 all fixedly connected to the outer wall of the plurality of first rotating shafts 32. A second motor 36 is fixedly connected to the left side of the outer casing 1. The inner wall of the outer casing 1 rotates... A plurality of second rotating shafts 37 are connected, with the right end of the lower second rotating shaft 37 and the output end of the second motor 36 fixedly connected. Two limiting plates 38 are fixedly connected to the outer walls of the two second rotating shafts 37. The reverse assembly includes a second gear 39 fixedly connected to the right end of the lower second rotating shaft 37. A connecting shaft 310 is rotatably connected to the right side of the housing 1. A third gear 311 is fixedly connected to the outer wall of the connecting shaft 310. Pulleys 312 are fixedly connected to the outer wall of the connecting shaft 310 and the right end of the second rotating shaft 37. A belt 313 is sleeved between the two pulleys 312. The third gear 311 meshes with the second gear 39.

[0032] By setting up the film conveying mechanism 3, the geotextile and geomembrane wound on the two second rotating shafts 37 are conveyed and extruded into composite molding by the first motor 31 and the second motor 36 driving the composite mechanism 2. The process is automated, and there is no need to set up an additional winding device in the subsequent process to drive the composite film conveying. This makes it convenient for workers to put the device into the production line for continuous processing and production, and further improves the practicality of the device.

[0033] A specific application of this embodiment is as follows: By setting up the composite mechanism 2, the hydraulic cylinder 22, which is fixed under the fixed block 21, is driven. The hydraulic cylinder 22 drives the four sections of the lower pressure plate 23 to descend in the slide groove 24. Under the downward pressure of the lower pressure plate 23, the slider 27 is driven to slide downward in the slide groove 24 by the elasticity of the spring 26. The guide rod 25 is set to limit the four ends of the lower pressure plate 23 and the sliders 27. The sliders 27 descend and drive the pressure roller 29 to press down through the connection of the two connecting plates 28. At this time, in conjunction with the film conveying mechanism 3, the geotextile and geomembrane are conveyed. The pressure roller 29 presses down on the geotextile and geomembrane located on the rotating roller 35. In conjunction with the film conveying mechanism 3, the rotating roller 35 is driven to rotate continuously to convey the composite film. The pressure roller 29 is limited by the limiting post 211 and the limiting groove 210. Rotating under the action of the position, the hydraulic cylinder 22 continues to drive. Since the pressure roller 29 is in a relatively fixed state in contact with the composite film, the lower pressure plate 23 continuously presses down to squeeze the spring 26. At this time, the spring 26 is in a compressed state. The elastic force of several springs 26 is applied to the composite film through the pressure roller 29. When the thickness of the composite film changes due to special circumstances, the buffering elastic force of the spring 26 further squeezes or stretches, forming a self-adjusting extrusion pressure, reducing sudden pressure peaks. This realizes the buffering effect of the spring 26 on the pressure roller 29 that is constantly pressed down by the hydraulic cylinder 22. It helps to stabilize the pressure fluctuations caused by composite films of different thicknesses being fed into the device during the pressing process, and to a certain extent avoids the composite film or machine from being damaged by constant pressure due to unexpected situations, thus ensuring the stable operation of the device.

[0034] By setting up the film conveying mechanism 3, the first motor 31 drives the rear-side 32 to rotate. The rear-side 32 drives the rear-side first gear 33 to rotate. With the cooperation of the chain belt 34 and several first gears 33, the rotation of the rear-side first gear 33 drives the other several first gears 33 to rotate synchronously through the linkage of the chain belt 34. This causes the several first gears 33 to drive the several fixedly connected 32 to rotate, completing the synchronous rotation of the several 32. The several 32 then drive the several rotating rollers 35 to rotate synchronously. At this time, the second motor 36 drives the lower-side second rotating shaft 37 to rotate. The lower-side second rotating shaft 37 drives the second gear 39 to rotate. Since the second gear 39 meshes with the third gear 311, the second gear 39 drives the connecting shaft 310 to rotate through the third gear 311. The connecting shaft 310 then drives the lower-side pulley 312 to rotate. With the cooperation of the two motors, the lower pulley 312 drives the upper pulley 312 to rotate synchronously through the linkage of the belt 313. The upper pulley 312 then drives the upper second shaft 37 to rotate. This completes the second motor 36 driving the two second shafts 37 to rotate in opposite directions, which facilitates the workers to better bond the geotextile and geomembrane together and facilitates the extrusion and bonding by the composite mechanism 2. Limiting plates 38 are set on the two second shafts 37 to limit the geotextile and geomembrane wound on the two second shafts 37. This realizes the automated process of conveying and extruding the geotextile and geomembrane wound on the two second shafts 37 by the first motor 31 and the second motor 36 in conjunction with the composite mechanism 2. The process does not require additional winding devices in subsequent processes to drive the composite membrane conveying, which makes it convenient for workers to put the device into the production line for continuous processing and production, and further improves the practicality of the device.
