Description

Technical Field

[0001] The utility model relates to the technical field of textile equipment, in particular to a fabric storage device with tension adjustment. Background Technique

[0002] At present, during the production of geotextiles, the flatness of the fabric surface has been increasingly emphasized. The flatness of the fabric surface is closely related to the fabric tension. When the fabric tension is too large, it will cause excessive stretching of the product. When the fabric tension is too small, it will cause insufficient stretching. These problems will cause wrinkles in the fabric during winding. Therefore, in order to avoid the above problems, a tension adjustment device is required during the production process. On the other hand, when the fabric roll is full, the fabric roll needs to be replaced. When changing the roll, the winding of the fabric stops, and the production line must also stop, affecting production efficiency. Moreover, the existing fabric storage mechanisms generally achieve it through the opposite movement of the upper fabric storage roller and the lower fabric storage roller. This opposite movement will cause the fabric surface to be stretched, affecting the fabric tension and resulting in a decline in product quality. Therefore, a fabric storage device with real-time tension adjustment is needed. Summary of the Invention

[0003] Aiming at the problems mentioned in the background technique, the purpose of the utility model is to provide a fabric storage device with tension adjustment.

[0004] A fabric storage device with tension adjustment includes a frame, a sending roller, a first tension detection mechanism, a first adjusting roller, a first driving roller, a second adjusting roller, an input fabric guiding roller, a lifting frame, an upper fabric storage roller, a lower fabric storage roller, an output fabric guiding roller, a third adjusting roller, a second driving roller, a second tension detection mechanism, and a winding roller. Among them, the first driving roller is located directly above the sending roller; the second adjusting roller is located directly above the first adjusting roller. The tops of the first to third adjusting rollers are fixedly connected to a swing arm, and the swing arm is fixedly connected to the telescopic rod of a cylinder; the tension detection mechanisms are respectively located at the input end and the output end of the geotextile; multiple upper fabric storage rollers arranged side by side front and back are fixedly installed on the lifting frame. The upper fabric storage rollers and the lower fabric storage rollers are arranged in an alternating manner so that the geotextile bypasses in a snake shape. The lower fabric storage rollers are fixedly installed on a crossbar; a pulley is provided at each of the left and right ends of the lifting frame and is fixedly connected to a chain, and can be pulled by a driving motor to move up and down along the frame through the chain.

[0005] The geotextile is fed into the device from the upper side of the sending roller, and sequentially passes through the lower side of the first tension detection mechanism, the lower side of the first adjusting roller, the upper side of the first driving roller, and the lower side of the second adjusting roller. Then it is wound into from the upper side of the input fabric guiding roller, down to the lower side of the frontmost lower fabric storage roller, and sequentially bypasses the upper fabric storage roller and the lower fabric storage roller in a snake shape. Then it exits from the lower side of the last lower fabric storage roller, up to the upper side of the output fabric guiding roller, and then sequentially passes through the lower side of the third adjusting roller, the upper side of the second driving roller, and the second tension detection mechanism, and finally is wound and output by the winding roller.

[0006] Among them, the tension detection mechanism is composed of three rollers arranged staggeredly up and down. There are two lower rollers and one upper roller. The geotextile is pressed by the front and rear rollers to maintain a tensioned state, and the change in the surface tension of the geotextile is detected by the middle roller.

[0007] Among them, the number of the lower fabric storage rollers is one more than that of the upper fabric storage rollers, ensuring that the geotextile is wound in and out from the lower fabric storage rollers.

[0008] Among them, a driving motor is arranged at the uppermost end of the frame. On the left and right sides along the frame direction directly below the lifting frame, there is a sprocket each, and the sprockets are connected by a chain drive to the driving motor.

[0009] The beneficial effects provided by the present utility model are:

[0010] In the present utility model, the change in the surface tension of the geotextile is detected by the tension detection mechanism. The tension detection mechanism is composed of three rollers arranged staggeredly up and down. The geotextile is pressed by the front and rear rollers to maintain a tensioned state, and the change in the surface tension of the geotextile is detected by the middle roller and the data is transmitted to the terminal. When the surface tension of the fabric exceeds or is lower than the set value, the terminal will control the telescopic cylinder to drive the swing arm to move, and the swing arm will drive the adjusting roller to move up and down, so as to achieve the purpose of adjusting the surface tension of the fabric in real time and avoid the occurrence of uneven surface tension of the fabric.

[0011] In the present utility model, through the combination of the tension detection and adjustment mechanism and the fabric storage mechanism, fabric storage can be carried out while adjusting the tension in real time, realizing non-stop roll change. When the winding of the geotextile stops and roll change is required, the second tension detection mechanism detects that the surface tension of the fabric becomes smaller. At this time, the terminal controls the third adjusting roller to swing downward. Moreover, since the previous production process has not stopped, the geotextile will accumulate on the production line. The first tension detection mechanism detects that the surface tension of the fabric becomes smaller, and the terminal will control the first adjusting roller and the second adjusting roller to swing downward to make the overall surface tension of the fabric reach the normal value. At the same time, the driving motor drives the lifting frame to rise, and the geotextile produced during the roll change process is collected in the fabric storage rack; similarly, when the roll change is completed, the terminal will also adjust the surface tension of the fabric to the normal value and lower the lifting frame to release the stored geotextile and continue production. Moreover, for the uneven surface tension caused by the stretching of the geotextile when the lifting frame rises and falls, it can also be adjusted by the up and down swing of the adjusting roller.

Specific embodiments

[0014] To make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0015] As Figure 1 shown, the present utility model provides a tension adjusting fabric storage device, which includes a frame 1, a sending roller 2, a first tension detection mechanism 3, a first adjusting roller 4, a first driving roller 5, a second adjusting roller 6, an input fabric guiding roller 7, a lifting frame 8, multiple upper fabric storage rollers 9 arranged side by side front and back, multiple lower fabric storage rollers 10 arranged side by side front and back, an output fabric guiding roller 11, a third adjusting roller 12, a second driving roller 13, a second tension detection mechanism 14, and a winding roller 15. Among them, the first driving roller 5 is directly above the sending roller 2; the second adjusting roller 6 is directly above the first adjusting roller 4. The tops of the first adjusting roller 4, the second adjusting roller 6, and the third adjusting roller 12 are respectively fixedly connected to the swing arm 16. One end of the swing arm 16 is connected to the frame 1, and the other end is fixedly connected to the telescopic rod of the cylinder 17. The movement relationship is as follows: the telescopic rod of the cylinder 17 drives the swing arm 16 to swing, and the swing arm 16 then drives each adjusting roller to move, so as to achieve the purpose of adjusting the fabric surface tension of the geotextile 18.

[0016] As Figure 1 shown, in the present utility model, the tension detection mechanism is composed of three rollers arranged vertically and staggeredly. There are two lower rollers and one upper roller. The geotextile 18 is pressed by the front and rear rollers to keep it in a tensioned state, and the fabric surface tension change of the geotextile 18 is detected by the middle roller.

[0017] As Figure 1 shown, in the present utility model, multiple upper fabric storage rollers 9 arranged side by side front and back are fixed on the lifting frame 8. The lower fabric storage rollers 10 are fixed on the cross bar 19. The upper fabric storage rollers 9 and the lower fabric storage rollers 10 are arranged staggeredly so that the geotextile 18 bypasses in a snake shape. The number of the lower fabric storage rollers 10 is one more than the number of the upper fabric storage rollers 9 to ensure that the fabric surface 18 enters and exits from the lower fabric storage rollers 10. An input fabric guiding roller 7 is provided above the front end of the lower fabric storage roller 10 to guide the fabric surface 17 into the fabric storage area, and an output fabric guiding roller 11 is provided above the end of the lower fabric storage roller 10 to output the geotextile 18.

[0018] As Figure 1As shown in the figure, in the present utility model, a driving motor 20 is provided at the uppermost end of the frame 1. On the left and right sides along the direction of the frame 1 directly below the lifting frame 8, a sprocket 21 is provided respectively. The sprocket 21 and the driving motor 20 are connected by a chain 22 for transmission. Among them, a pulley 23 is provided at each of the left and right ends of the lifting frame 8, and it can move up and down along the fixed frame 1. Among them, the chain 22 is fixedly connected to the lifting frame 8, and the up and down movement of the lifting frame 8 is realized by the driving motor 20 driving the chain 22 to pull.

[0019] As Figure 1 shown in the figure, in the present utility model, the geotextile 18 is fed into the device from the upper side of the sending roller 2, and sequentially passes through the lower side of the first tension detection mechanism 3, the lower side of the first adjusting roller 4, the upper side of the first driving roller 5, and the lower side of the second adjusting roller 6. Then it winds into the storage area from the upper side of the input guiding cloth roller 7, winds around the upper storage cloth roller 9 and the lower storage cloth roller 10 in a snake shape in sequence, and then winds out from the upper side of the output guiding cloth roller 11. Then it passes through the lower side of the third adjusting roller 12 and the upper side of the second driving roller 13 and the second tension detection mechanism 14 in sequence, and finally is wound and output by the winding roller 15. During this process, if the winding of the geotextile 18 stops and the roll change starts, the second tension detection mechanism 14 detects that the cloth surface tension becomes smaller and transmits the data to the terminal. The terminal will control the air cylinder 17 to drive the third adjusting roller 12 to swing downward. At this time, since the winding stops while the previous production process does not stop, the produced geotextile 18 increases. The first tension detection mechanism 3 detects that the cloth surface tension becomes smaller, and the air cylinder 17 drives the first adjusting roller 4 and the second adjusting roller 6 to swing downward, so that the overall cloth surface tension reaches the normal value. At the same time, the driving motor 20 drives the lifting frame 8 to rise, and collects the geotextile 18 produced during the roll change process in the storage cloth rack. Similarly, when the roll change ends and the winding restarts, the second tension detection mechanism 14 detects that the cloth surface tension increases, and the air cylinder 17 drives the third adjusting roller 12 to swing upward. At this time, the first tension detection mechanism 3 detects that the cloth surface tension becomes larger, and the air cylinder 17 drives the first adjusting roller 4 and the second adjusting roller 6 to swing upward, so that the overall cloth surface tension reaches the normal value. At the same time, the driving motor 20 drives the lifting frame 8 to descend, and releases the stored geotextile 18.

[0020] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
