Description

Technical Field

[0001] The present invention belongs to the technical field of textile equipment, and particularly relates to a pretreatment device for the production of rayon grey cloth. Background Art

[0002] Rayon grey cloth is a fabric made of regenerated cellulose fiber (rayon). Due to its softness, comfort, breathability and other characteristics, it is widely used in clothing and home textile products. After the rayon grey cloth is produced, a smoothing agent is usually used to treat the rayon grey cloth to reduce the surface roughness and make the grey cloth smoother, which is convenient for subsequent use.

[0003] When it is necessary to smooth the rayon grey cloth, in the prior art, generally, the produced rayon grey cloth is taken off from the winding reel by the staff, then laid flat on the surface of the treatment platform, and then the smoothing agent is sprayed on the surface of the rayon grey cloth to smooth the rayon grey cloth. However, this process is relatively complex and requires manual operation to lay the rayon grey cloth flat on the surface of the treatment platform, which reduces the treatment efficiency of the rayon grey cloth. After the treatment of the rayon grey cloth is completed, the rayon grey cloth needs to be wound around the winding reel again. At this time, one end of the rayon grey cloth needs to be fixed on the outer wall of the winding reel, and then the staff tightly pulls the other end of the rayon grey cloth, and then makes the winding reel rotate continuously to wind the tightened rayon grey cloth around the winding reel. At this time, the rayon grey cloth is pulled horizontally. Rayon grey cloth is usually woven by warp yarns (longitudinal) and weft yarns (transverse). Due to the characteristics of the fabric structure, the warp yarns and weft yarns often show different behaviors when stressed. When pulled horizontally, the weft yarns are stretched, while the warp yarns cannot move freely due to the restraint of the interweaving points, resulting in the formation of wrinkles in the longitudinal direction of the warp yarns. After the rayon grey cloth with longitudinal wrinkles is wound around the winding reel, wrinkles will be formed on the surface of the rayon grey cloth, which will directly affect the appearance of the finished product, resulting in an uneven surface of the product, and greatly reducing the pretreatment effect and reliability of the rayon grey cloth.

[0004] Therefore, we propose a pretreatment device for the production of rayon grey cloth to solve the above problems. Summary of the Invention

[0038] The operating principle of the present invention is described as follows:

[0039] In the present invention, when it is necessary to pre-treat the rayon grey fabric after production, first, the second motor 1110 is controlled to start, driving the third electric telescopic rod 1111 to rotate, so that the clamping rod 1114 and the fourth electric telescopic rod 1113 rotate 90 degrees without blocking the fixed cylinder 118. Then, the staff puts the winding reel wrapped with rayon grey fabric on the outside of the fixed cylinder 118. After that, the second motor 1110 is controlled to rotate in the reverse direction, and the clamping rod 1114 is located at one end of the fixed cylinder 118. Then, the fourth electric telescopic rod 1113 is controlled to start, driving the clamping rod 1114 to move towards the inside of the fixed cylinder 118. After that, the fifth electric telescopic rod 1115 is controlled to start, driving the clamping plate 1116 to move towards the inner wall of the fixed cylinder 118, and the fixed cylinder 118 is fixed by the clamping plate 1116. Then, the sixth electric telescopic rod 1117 is controlled to start, driving the clamping plate 1118 to move, and the outer winding reel is fixed by the clamping plate 1118. After the winding reel is fixed, a group of second electric slide rails 132 corresponding to both sides of the bottom plate 1 are controlled to start, driving the corresponding second slide plate 133 to move to one end of the winding reel. Then, the corresponding ninth electric telescopic rod 136 is controlled to start, so that the anti-fold plate 1317 in the first U-shaped plate 137 is in the same plane as one end of the winding reel. Then, the staff puts one end of the rayon grey fabric into the two first U-shaped plates 137. After that, the corresponding twelfth electric telescopic rod 1316 is controlled to start to fix one end of the rayon grey fabric. Then, the corresponding second electric slide rail 132 and the first motor 117 are controlled to start simultaneously, so that during the continuous rotation of the winding reel, it cooperates with the movement of the anti-fold plate 1317, and one end of the rayon grey fabric moves under the pressing plate 127. Then, the seventh electric telescopic rod 126 is controlled to start, and one end of the rayon grey fabric is fixed by the pressing plate 127. And during the process of the two first U-shaped plates 137 driving the rayon grey fabric to move, the eighth electric telescopic rods 134 above the other two second electric slide rails 132 respectively arranged on both sides of the bottom plate 1 will start, driving the first support plate 135 to move upward without blocking the first U-shaped plate 137 driving the rayon grey fabric to move. After one end of the rayon grey fabric is fixed by the pressing plate 127, the third motor 124 is controlled to rotate, so that the collecting rod 123 rotates continuously, and the rotation speed of the third motor 124 matches the rotation speed of the first motor 117 to ensure that the rayon grey fabric is stably wound around the outer wall of the collecting rod 123. And when the first U-shaped plate 137 drives the rayon grey fabric to move under the second nozzle 8, at this time, the first nozzle 4, the second nozzle 8 and the water pump 10 are controlled to start simultaneously, and the smoothing agent in the liquid storage shell 5 is evenly sprayed on the surface of the rayon grey fabric through the first nozzle 4 and the second nozzle 8. After the two first U-shaped plates 137 pass through the two first U-shaped plates 137 in the middle, at this time, the two eighth electric telescopic rods 134 in the middle are controlled to start, so that the corresponding first U-shaped plate 137 moves to the rear part of the previous first U-shaped plate 137.And at this time, the first U-shaped plates 137 are all located inside the upper and lower sides of the rayon grey fabric. Then, control the corresponding twelfth electric telescopic rod 1316 to start, driving the corresponding pressing plate 127 to clamp both sides of the rayon grey fabric. Then, control the ninth electric telescopic rod 136 in the middle to contract, pulling both sides of the rayon grey fabric to prevent longitudinal creases from occurring on the rayon grey fabric. After the first U-shaped plates 137 of the previous group move to one side of the collecting rod 123, at this time, control the corresponding twelfth electric telescopic rod 1316 and the ninth electric telescopic rod 136 to contract and return to their original positions. Then, control the corresponding second electric slide rail 132 and the eighth electric telescopic rod 134 to start, driving the first support plate 135 to move downward, enabling the first U-shaped plates 137 of the first group to move towards the winding drum. As the first U-shaped plates 137 of the second group in the middle move to one side of the third U-shaped plate, control the corresponding ninth electric telescopic rod 136 and the twelfth electric telescopic rod 1316 to start according to the above method to continue tightening both sides of the rayon grey fabric, and the corresponding second electric slide rail 132 follows the movement. After the first U-shaped plates 137 of the first group move to the rear side of the first U-shaped plates 137 of the third group, control the eighth electric telescopic rod 134, the ninth electric telescopic rod 136, and the twelfth electric telescopic rod 1316 to start to continue tightening both ends of the rayon grey fabric, ensuring that there are no creases on the surface of the rayon grey fabric when it is wound around the collecting rod 123. After the first U-shaped plates 137 of the second group move to one side of the collecting rod 123, control the corresponding electrical components according to the above method to make the first U-shaped plates 137 of the second group re-locate to one side of the first U-shaped plates 137, thereby continuously longitudinally tightening both ends of the rayon grey fabric, while the transverse direction of the rayon grey fabric is tightened by the collecting rod 123 and the winding drum. At this time, after the surface of the rayon grey fabric is sprayed with a smoothing agent, the surface of the rayon grey fabric can maintain a tightened state and have no creases, and the moving speed of the second electric slide rail 132 when driving the first U-shaped plate 137 to move is all matched with the moving speed of the collecting rod 123 for the rayon grey fabric, facilitating continuous longitudinal tightening of the rayon grey fabric. After all the rayon grey fabric on the winding drum is wound around the collecting rod 123, at this time, the smoothing treatment of the rayon grey fabric is completed, and when the rayon grey fabric sprayed with the smoothing agent is wound around the collecting rod 123, the pressure applied between the rayon grey fabrics helps the surface of the rayon grey fabric to be smoother. Then, the staff puts one end of the rayon grey fabric into the first group of second U-shaped plates 1315 on both sides of the bottom plate 1. Then, control the twelfth electric telescopic rod 1316 to start to fix both ends of the rayon grey fabric. Then, control the first electric telescopic rod 114 and the third electric telescopic rod 1111 to start, driving the winding drum to move upward so that the winding drum moves above the collecting rod 123. Then, control the first electric slide rail 112 to start, driving the first slide plate 113 and the winding drum to move to the other side of the bottom plate 1, facilitating the collection of the dried rayon grey fabric. Then, control the third electric slide rail 1310 and the third motor 124 of the first group to start simultaneously,Continuously release the rayon grey fabric wound on the collecting rod 123, so that one end of the rayon grey fabric moves to the surface of the winding drum. After the staff fixes one end of the rayon grey fabric on the surface of the winding drum, control the first motor 117 to continue rotating, so that the rayon grey fabric on the collecting rod 123 is rewound on the outer wall of the winding drum. At the same time, when one end of the rayon grey fabric moves below the first drying plate 1320, control the thirteenth electric telescopic rod 1319, the first drying plate 1320, the fourteenth electric telescopic rod 1322 and the second drying plate 1323 to start simultaneously, so that the first drying plate 1320 and the second drying plate 1323 heat and dry the rayon grey fabric after approaching the rayon grey fabric, making the surface of the rayon grey fabric dry and facilitating subsequent use. And when the second U-shaped plate 1315 of the first group drives one end of the rayon grey fabric to move to the second U-shaped plate 1315 of the second group, control the corresponding eleventh electric telescopic rod 1314 and the twelfth electric telescopic rod 1316 to start, and tighten both sides of the rayon grey fabric. According to the above steps, control the third electric slide rail 1310, the tenth electric telescopic rod 1312, the eleventh electric telescopic rod 1314 and the twelfth electric telescopic rod 1316 of each group to start in turn, so that the anti-fold plate 1317 in the second U-shaped plate 1315 can continuously tighten the rayon grey fabric, ensuring that when the rayon grey fabric is rewound on the winding drum, there are no creases in the longitudinal and transverse directions of the rayon grey fabric, improving the reliability during the smoothing process of the rayon grey fabric, being able to automatically smooth the rayon grey fabric wound on the winding drum, and using the collecting rod 123 to wind the rayon grey fabric after spraying the smoothing agent, making the surface of the rayon grey fabric smoother due to the pressure exerted between the rayon grey fabrics. At the same time, the rayon grey fabric wound on the collecting rod 123 can be rewound on the outer wall of the winding drum. During this process, the rayon grey fabric can be heated and dried to keep the rayon grey fabric dry, reducing the influence after spraying the smoothing agent on the rayon grey fabric. At the same time, during the process of winding the rayon grey fabric on the collecting rod 123 and rewinding it on the winding drum, the two ends of the rayon grey fabric can always be longitudinally tightened, preventing the rayon grey fabric from forming wrinkles longitudinally when only the rayon grey fabric is transversely tightened, resulting in wrinkles on the surface when the rayon grey fabric is wound on the collecting rod 123 and the winding drum, affecting the appearance of the finished product and causing the surface of the product to be uneven, improving the pretreatment effect and working efficiency of the device on the rayon grey fabric.
