[0002] Geotextile, also known as geotextile fabric, is a permeable geosynthetic material made of synthetic fibers by needling or weaving. Geotextile is one of the new geosynthetic materials, and the finished product is in the shape of a cloth, generally with a width of 4-6 meters and a length of 50-100 meters. Geotextiles are divided into woven geotextiles and non-woven filament geotextiles.

[0003] When geotextiles are produced, they need to be cut to meet the length requirements. When the existing geotextile cutting equipment works, after the geotextile is cut, for the geotextile behind the cutting knife, due to the softness of the geotextile, it is difficult to convey it by pushing, so at present, only the method of manual pulling by personnel can be used to pull the geotextile behind the cutting knife to the front of the cutting knife and connect it to the winding roller.

[0004] However, the method of manual pulling increases the pulling strength of personnel on the one hand, and on the other hand, the operation position is relatively close to the cutting knife, so it is easy to cause danger. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the utility model without creative efforts shall fall within the protection scope of the utility model.

[0018] As shown Figures 1-3 in the figure, a geotextile 13 cutting device includes a workbench 1, a gantry plate 9, a cylinder 8, a moving plate 6, a cutting knife 11, a motor 17, a pulley set 18 and a pair of conveyor rollers 3. A pair of mounting grooves 2 are formed on the workbench 1, and the pair of conveyor rollers 3 are respectively arranged in the mounting grooves 2. The gantry plate 9 straddles the workbench 1, and both sides of the gantry plate 9 cover both ends of the mounting grooves 2. Axle shafts 15 are fixedly arranged along the axial positions of the pair of conveyor rollers 3, and the conveyor rollers 3 are rotationally connected to the side walls of both sides of the gantry plate 9 through the axle shafts 15. The axle shaft 15 on one side penetrates out of the gantry plate 9 and is connected through the pulley set 18, and the axle shaft 15 on the other side penetrates out of the gantry plate 9 and is connected to the output end of the motor 17. The motor 17 is fixedly connected to the outer side wall of the gantry plate 9. A cutting table 14 is arranged on the side surface of the conveyor roller 3, and the cutting table 14 can be flush with the upper surface of the workbench 1. The cylinder 8 is fixedly arranged at the central position of the top of the gantry plate 9, and the telescopic end of the cylinder 8 is fixedly connected to the central position of the upper surface of the moving plate 6. The cutting knife 11 is arranged at the central position of the moving plate 6, and a plurality of pressing components are respectively arranged on both sides of the moving plate 6 corresponding to the cutting knife 11. The pressing component includes a limiting rod 10, a pressing plate 12 and a compression spring 5. The limiting rod 10 vertically and movably penetrates through the moving plate 6. The upper end of the limiting rod 10 is connected with a clamping plate 7, and the lower end is connected to the upper surface of the pressing plate 12. The compression spring 5 is sleeved on the limiting rod 10. The upper end of the compression spring 5 is connected to the bottom surface of the moving plate 6, and the lower end is connected to the upper surface of the pressing plate 12. Rubber particles 16 are evenly arranged on the side surface of the conveyor roller 3. A backing plate 4 is arranged on the workbench 1 at the position corresponding to the cutting knife 11.

[0019] The detailed connection means are well-known techniques in the art. The following mainly introduces the working principle and process, which are as follows:

[0020] According to the attached Figures 1-3 drawings of the specification, it can be seen that the attached drawings of the present utility model only show the cutting device, and there is a winding roller or a pulling and conveying device for conveying the geotextile 13 on the right side (front) of the cutting device, which is the prior art.

[0021] When the utility model works, the motor 17 drives the rotating shaft 15 and the conveying roller 3 to rotate. Since the two conveying rollers 3 are connected and driven by a pulley set 18, the two conveying rollers 3 rotate simultaneously, making the cutting table 14 on the conveying roller 3 flush with the upper surface of the workbench 1, and the motor 17 pauses working. The telescopic end of the cylinder 8 on the gantry plate 9 contracts, driving the moving plate 6 and the cutting knife 11 to move upward, away from the workbench 1. The geotextile 13 is wound by the winding roller. After a certain length, the winding stops. The telescopic end of the cylinder 8 extends, driving the moving plate 6 to move downward, thereby driving the cutting knife 11 and the pressing assembly to move downward. The pressing assembly presses the geotextile 13 against the cutting table 14 of the driving roller. Then, the cutting knife 11 continues to move downward to cut the geotextile 13. After cutting, the telescopic end of the cylinder 8 retracts, separating the cutting knife 11 and the pressing assembly from the geotextile 13. The geotextile 13 on the right side (in front of the cutting knife 11) after cutting is wound by an external winding roller, and the geotextile 13 on the left side (behind the cutting knife 11) at the cutting position is ready for conveying. At this time, the motor 17 is started, and the motor 17 rotates to drive the two conveying rollers 3 to rotate clockwise. Since the cutting table 14 of the conveying roller 3 is flush with the upper surface of the workbench 1, its side surface must be higher than the workbench 1, as Figure 3 shown. Therefore, when the conveying roller 3 rotates, friction is generated between its side surface and the geotextile 13, which can drive the geotextile 13 to move to the right until it moves to the end away from the cutting knife 11, and then personnel can install it on the winding roller or the conveying device. Compared with the prior art, the utility model does not require personnel to reach out to the cutting knife 11 to pull the geotextile 13. Instead, it can convey the geotextile 13 to a position in front of the cutting knife 11 and away from the cutting knife 11 through the conveying roller 3, reducing the pulling strength of personnel and improving safety. Moreover, the cutting table 14 provided on the conveying roller 3 can be flush with the workbench 1, and cooperate with the pressing assembly to press the geotextile 13, ensuring stability and not affecting the cutting quality of the cutting knife 11.

[0022] Among them, the pressing assembly includes a limiting rod 10, a pressing plate 12 and a compression spring 5. The limiting rod 10 vertically and movably penetrates the moving plate 6. The upper end of the limiting rod 10 is connected with a clamping plate 7, and the lower end is connected with the upper surface of the pressing plate 12. The compression spring 5 is sleeved on the limiting rod 10. The upper end of the compression spring 5 is connected with the bottom surface of the moving plate 6, and the lower end is connected with the upper surface of the pressing plate 12.

[0023] When working, the telescopic end of the cylinder 8 drives the moving plate 6 to move downward, so that the pressing plate 12 first contacts the geotextile 13, and the compression spring 5 is compressed. The reaction force causes the pressing plate 12 to press the geotextile 13 against the cutting table 14 of the conveying roller 3, ensuring the stability of the geotextile 13 and the cutting quality.

[0024] Among them, rubber particles 16 are uniformly arranged on the side surface of the conveying roller 3. The rubber particles 16 can increase the friction with the geotextile 13 and can convey the geotextile 13 on the left more smoothly.

[0025] Among them, a backing plate 4 is arranged at the position on the workbench 1 corresponding to the cutting tool 11 to provide cutting quality and the service life of the cutting tool 11.

[0026] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
