[0002] Since most flexible materials are produced and transported in rolls, when they arrive at the user's factory, an important process is to convert the rolled composite geotextile into a multi-layer flat state so that it can be easily cut and used. Therefore, automated production equipment such as cloth pulling devices came into being.

[0003] In the processing of composite geotextiles, especially in the flattening and finishing process, the traditional flattening method mainly uses linear flattening equipment to flatten the surface of the fabric by applying mechanical pressure. However, these traditional methods have exposed some significant defects in practice, especially in dealing with the edges and local wrinkles of the fabric. The mechanical structure of the equipment makes the pressure mainly concentrated in the central area of ​​the pressure plate, while the pressure on the edge is relatively small, so it is difficult to achieve a uniform effect. This problem of uneven pressure distribution is particularly significant when processing composite geotextiles. Therefore, it is necessary to redesign the composite geotextile pulling device to address the above problems. Utility Model Content

[0022] By driving the small pressure roller 16 to slide through the reciprocating screw 11, the small pressure roller can move more flexibly along the surface of the cloth to adapt to various deformations and unevenness of the cloth. Since the surface area of ​​the pressure roller 16 is small, its contact area is small, and the pressure distribution can be controlled more accurately.

[0023] Reference Figure 2 and Figure 3 The inner wall of the frame 7 is fixedly connected to the limit rod 12, the screw sleeve 13 is slidably connected to the outer wall of the limit rod 12, the ends of the two sets of slide bars 17 are fixedly connected to the limit blocks 19, the radius of the limit blocks 19 is larger than the radius of the slide bars 17, and the outer wall of the slide bars 17 is sleeved with a spring 18, one end of the spring 18 is fixedly connected to the upper end surface of the slide plate 15, and the other end of the spring 18 is fixedly connected to the lower end surface of the limit block 19, the side wall of the frame body 1 is rotatably connected with a transmission wheel 18 and a transmission wheel 2 9, the transmission wheel 18 is coaxially fixedly connected to the adjacent roller 14, the transmission wheel 2 9 is coaxially fixedly connected to the reciprocating screw 11, and the transmission wheel 18 is connected to the transmission wheel 2 9 through a belt 10;

[0024] The radius of the transmission wheel 1 8 is greater than that of the transmission wheel 2 9 . When the roller 14 drives the transmission wheel 1 8 to rotate, the transmission wheel 2 9 that is arranged in cooperation with the transmission wheel 1 8 accelerates the motion, thereby accelerating the rotation of the reciprocating screw 11 .

[0025] The side wall of the frame body 1 is fixedly connected with a side plate 2 , the outer wall of the side plate 2 is rotatably connected with a roller body 3 , the side wall of the frame body 1 is fixedly connected with a servo motor 6 , and the output shaft of the servo motor 6 is coaxially fixedly connected with the rotating roller 14 .

[0026] In the utility model, the specific function of the device is: when using the device, the roller body 3 is placed on the upper end of the side plate 2, and one end of the composite geotextile is attached to the upper end surface of the Velcro 5. The servo motor 6 is used to drive the roller 14 to rotate, and the transmission belt 4 provided in conjunction with the device can drive the composite geotextile to move horizontally. During the horizontal movement, the composite geotextile is gradually flattened from the roller body 3 to the transmission belt 4 to achieve the initial flattening of the fabric. The synchronously provided transmission wheel 1 8 and the transmission wheel 2 9 can drive the reciprocating screw 11 to rotate, and then the screw sleeve 13 on its threaded section drives the outer wall slide plate 15 and the pressure roller 16 at the lower end to slide horizontally on the upper end surface of the composite geotextile, and slides along the upper end surface of the composite geotextile during sliding. At the same time, the force applied by the pressure roller 16 can not only flatten the middle part, but also process the edge area, thereby avoiding the problem of insufficient edge pressure in the traditional flattening method, and the provided spring 18 can make the provided pressure roller 16 always tightly against the upper end surface of the composite geotextile.

In this process, the cloth is continuously flattened and compacted, and the cloth pulling and flattening are carried out simultaneously.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
