[0002] Composite geomembrane is an engineering material composed of a composite membrane layer and a geotechnical part. The composite membrane layer is usually composed of two or more layers of materials, such as polyethylene, polypropylene, chlorinated polyethylene, etc. The geotechnical part uses plastic geogrids, geotextiles and other materials. Composite geomembrane has the characteristics of anti-seepage, waterproof, anti-corrosion, chemical corrosion resistance, and environmental protection. It is often used in engineering construction in the fields of water conservancy, mining, transportation, and environmental protection.

[0003] The utility model patent with publication number CN217911190U discloses a composite geomembrane surface roughening device, including a table top, the upper side wall of the table top is symmetrically fixedly connected to two support frames, the side walls of the two support frames on opposite sides are fixedly connected with nozzles, the nozzles are plate-like structures, the pipe walls of the nozzles are fixedly connected with multiple groups of nozzles, and the geotextile membrane passes between the two nozzles. Two nozzles are used to spray and roughen the two sides of the composite geomembrane, which improves the work efficiency. However, the nozzle area is fixed and cannot be adjusted for composite geomembranes of different widths. When the width of the composite geomembrane is narrow, excess material may be sprayed out, wasting raw materials.

In addition, the terms "first", "second", etc. are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, features defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "multiple" means two or more.

[0019] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0020] In conjunction with the accompanying drawings, a composite geomembrane surface roughening device includes a chassis 1, a guide roller 2, and a spraying frame 3. The guide roller 2 converts the horizontally transported composite geomembrane into vertical transport. Two spraying frames 3 are provided, which are respectively located on the left and right sides of the vertical composite geomembrane. A supporting beam 4 for supporting the spraying frame 3 is provided in the chassis 1. The spraying frame 3 is slidably set on the supporting beam 4. A mobile driving mechanism is provided on the supporting beam 4 to drive the spraying frame 3 to slide back and forth along the supporting beam 4. Two limit plates 5 are slidably provided on the supporting beam 4. The limit plates 5 are located on the front and rear sides of the spraying frame 3, and a limit switch 6 is provided on the side close to the spraying frame 3 for controlling the reverse action of the mobile driving mechanism. The composite geomembrane is located between the two limit plates 5. A feeding mechanism is provided on the chassis 1, and the feeding mechanism drives the composite geomembrane into the chassis 1.

[0021] The mobile driving mechanism includes a one-way threaded rod 7 and a driving motor 8. The supporting crossbeam 4 is provided with a strip slide 9. The output shaft of the driving motor 8 is connected to the end of the one-way threaded rod 7, driving the one-way threaded rod 7 to rotate and is arranged in the strip slide 9. The side of the spraying rack 3 that is away from each other cooperates with the strip slide 9. The spraying rack 3 is provided with a threaded hole 1, which cooperates with the one-way threaded rod 7 through the threaded hole 1. The limit switch 6 is electrically connected to the driving motor 8. When the spraying rack 3 contacts the limit switch 6, the driving motor 8 switches the rotation direction. The control circuit is a prior art and will not be described here.

[0022] The driving motors 8 on the two mobile driving mechanisms are of the same model and operate at the same speed.

[0023] The limit plate 5 matches the strip slide 9, and a through hole is provided on the limit plate 5 corresponding to the one-way threaded rod 7, and the one-way threaded rod 7 passes through the through hole to prevent the limit plate 5 from affecting the rotation of the one-way threaded rod 7. The limit plates 5 on the same side of the two supporting beams 4 are fixedly connected at one end close to each other, so that the composite geomembrane is located between the two limit plates 5. The chassis 1 is provided with a limit drive mechanism for driving the limit plates 5 on both sides to open and close. When working, the position of the limit plate 5 is adjusted so that its inner side is close to the side of the composite geomembrane, so as not to affect the transportation of the composite geomembrane.

[0024] The limit drive mechanism includes a bidirectional threaded rod 10 and a drive motor 11. The bidirectional threaded rod 10 is arranged parallel to the supporting beam 4. The output end of the drive motor 11 is connected to the end of the bidirectional threaded rod 10 to drive the bidirectional threaded rod 10 to rotate. A slider 12 is provided on the limit plate 5. A threaded hole 2 is provided in the middle of the slider 12, and the slider 12 cooperates with the bidirectional threaded rod 10 through the threaded hole 2, thereby driving the slider 12 to open and close, and then driving the limit plate 5 to open and close.

[0025] The feeding mechanism includes an active roller 13, a driven roller 14 and a second driving motor 15. The composite geomembrane is clamped between the active roller 13 and the driven roller 14. The output shaft of the second driving motor 15 is connected to the central axis of the active roller 13 to drive the active roller 13 to rotate and feed the material.

[0026] As attached Figure 1 , 2 As shown, a drying box is provided at the bottom of the chassis 1, and the roughened composite geomembrane is sent out after being dried. A guide roller 2 is provided at the bottom of the drying box to guide the composite geomembrane to be transported horizontally again.

[0027] A hot melt device is provided in the chassis 1, and a conveying pipe is connected to the hot melt device, and the hot melt material is sent to the spray rack 3 through the conveying pipe. An air pipeline (not shown in the figure) is also provided in the chassis 1, and the air pipeline is connected to the air inlet of the spray rack 3, which is used to provide high-pressure airflow for the spray rack 3 to spray the hot melt material.

[0028] When the utility model is implemented in a specific way, before work, the position of the limit plate 5 is adjusted according to the width of the composite geomembrane, and the driving motor 11 is started to drive the bidirectional threaded rod 10 to rotate. Since the limit plate 5 is limited by the strip slide groove 9, the sliding block 2 12 cannot rotate along with the rotation of the bidirectional threaded rod 10, so that when the bidirectional threaded rod 10 rotates, the sliding block 2 12 opens and closes, driving the limit plate 5 to open and close and move close to the composite geomembrane; the driving motor 2 15 rotates to drive the composite geomembrane to move and send it into the chassis, which is guided by the guide roller 2 and converted into vertical transportation. The spraying frame 3 is located on both sides of the composite geomembrane, and the driving motor 1 8 drives the unidirectional threaded rod 7 to rotate. When the spraying frame 3 contacts the limit switch 6, the driving motor 1 8 rotates in the opposite direction (the driving motor 1 8 rotates slowly to achieve an emergency stop in the reverse direction), driving the spraying frame 3 to move back and forth for spraying. The sprayed composite geomembrane enters the drying box for drying, and then is sent out for winding.

[0029] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
