Description

Technical Field

[0001] The invention specifically relates to a polyester fabric pre-forming device, belonging to the technical field of polyester fabric production. Background Art

[0002] Polyester fabric is a kind of chemical fiber clothing fabric that is very commonly used in daily life. Its biggest advantage is that it has good wrinkle resistance and shape retention. Therefore, it is suitable for outdoor products such as outerwear, various bags and tents. After textile production, polyester fabric has certain internal stress in the weaving process, so it is often necessary to pre-shape the polyester fabric after it is woven into the fabric. The commonly used method is preheating and shaping. The purpose of preheating and shaping is to eliminate stress through the process of tension and relaxation of the fabric, so that the size of the fabric is fully stable and the creases that appear in the weaving process of the fabric are eliminated. However, in the process of pre-shaping, the prior art can often only pull the fabric horizontally, that is, pull the fabric in the forward direction. Even if the fabric can be pulled vertically, the fabric often needs to stop moving during the pulling process. Moreover, when the prior art pulls the fabric horizontally, it often affects the speed of fabric winding and the effect of winding. At the same time, the fabric needs to be watered when it is pre-shaped. The existing watering methods mostly use direct immersion in water or spraying. If it is directly immersed in water, it will cause too much water in the fabric, which is not conducive to subsequent drying. If spraying is used, the sprayed water cannot quickly penetrate the fabric.

[0003] As disclosed in publication number (CN210765894U), the pre-forming device for spandex fabrics comprises a water-passing mechanism, the water-passing mechanism is provided with an adjusting mechanism, the adjusting mechanism comprises a water tank, a controller, and a heating pipe, the controller is installed at the front of the water tank, the heating pipe is installed inside the water tank, a temperature sensor is installed on one side of the heating pipe, a conveying frame is provided on the side of the water tank, a No. 3 rotating roller is provided on the conveying frame, a tensioning roller is provided on one side of the No. 3 rotating roller, a No. 2 electric telescopic column is installed below the tensioning roller, a No. 3 electric telescopic column is provided on one side of the No. 2 electric telescopic column, a fixing frame is installed on the No. 3 electric telescopic column, and an electric telescopic rod is provided on the fixing frame. The utility model has the advantages of simple structure, convenient operation, great saving of manpower and guaranteed production quality. Even if the above-mentioned prior art can pull the fabric vertically, it needs to stop moving forward. Moreover, when the above-mentioned prior art directly pulls the fabric horizontally by adjusting the tensioning roller, the fabric will be stretched and relaxed when being rolled up, resulting in insufficient stability of the subsequent rolling. Moreover, the prior art wets the fabric by directly immersing the fabric in water, resulting in excessive moisture inside the fabric, which is not conducive to subsequent drying. Summary of the invention

Water outlet holes 22 are respectively provided on the water outlet shell 21 and the hollow water pipe 20.

[0025] When the fabric needs to be pre-shaped, first place the rolled fabric on the support sleeve 17, then clamp the support main shaft 16 with the support side plate 15, and tighten the locking nuts at both ends of the support main shaft 16 to fix the support main shaft 16 with the support side plate 15, then place the fabric under the water outlet shell 21, fit the water outlet shell 21 with the fabric, and then tighten the fixing nut on the support screw 18 to fix the water outlet shell 21, then pass the fabric through the two pulling components 5 respectively, and then place the fabric under the support inner wheel 8, and the inner of the water outlet shell 21 Sealing rings 24 are respectively provided on the walls, and the sealing rings 24 can prevent the water entering the water outlet shell 21 from flowing out from both ends of the water outlet shell 21. Sponge pads 25 are provided on the side walls of the water outlet shell 21, and the sponge pads 25 are beneficial to protecting the fabrics. A hot water tank 35 is provided on the top outer wall of the fixed bottom plate 1, and a heating coil is provided inside the hot water tank 35. The temperature of the water inside the hot water tank 35 can be adjusted by the heating coil. A water pump 36 is installed on the top outer wall of the hot water tank 35, and the output end of the water pump 36 is connected to the hollow water pipe 20 through a plastic pipe.

[0026] The pulling assembly 5 includes a U-shaped frame 501, which is located on the top outer wall of the support frame 2. A downward pressure cylinder 502 is installed on the top outer wall of the U-shaped frame 501. The output end of the downward pressure cylinder 502 is connected to a roller frame 503. A downward pressure roller 505 is rotatably connected to the roller frame 503. A driving roller 506 is rotatably connected to the U-shaped frame 501. A driving motor 507 is installed on one side wall of the U-shaped frame 501. The output end of the driving motor 507 is connected to the driving roller 506. Guide rods 504 are respectively installed on the top outer wall of the roller frame 503. The guide rods 504 are movably connected to the U-shaped frame 501. The rod 504 can guide the roller frame 503 when the roller frame 503 moves up and down, so that the roller frame 503 can be lifted and lowered more smoothly. During the movement of the fabric during the pre-setting, the hot water in the hot water tank 35 is pumped into the hollow water pipe 20 through the water pump 36, and the hot water flows into the water outlet shell 21 through the water outlet hole 22 on the hollow water pipe 20, and then flows out through the water outlet hole 22 on the water outlet shell 21. During the process of the fabric moving forward, it always moves close to the water outlet shell 21, so that the water flowing out of the water outlet shell 21 can penetrate the fabric more quickly, so that the fabric can be quickly soaked without being immersed in water, thereby avoiding the influence of excessive water content in the fabric on the back. During the continuous drying, the downward pressure cylinder 3 502 drives the downward pressure roller 505 to press the fabric during the movement. The rotation speed of the driving motor 507 on the U-shaped frame 3 501 on the side close to the supporting frame 3 is consistent with the winding speed, and is slightly greater than the rotation speed of the driving motor 507 on the side close to the supporting side plate 15, so that the fabric can be tightened between the two driving rollers 506 without affecting the subsequent winding. When the fabric moves out from between the two driving rollers 506, it will become relaxed again, realizing the elimination of stress on the fabric. The U-shaped frame 7 is driven down by the downward pressure cylinder 4, and the adjusting pull ring 9 is placed against the fabric. Then, the cylinder is pushed 12 drives the adjusting push fork 13 to move, and the adjusting push fork 13 can drive the adjusting pull ring 9 to move horizontally, so that the fabric is laterally tightened. At the same time, the supporting inner wheel 8 can still rotate, so that the fabric can continue to move forward, so it will not affect the production speed. When the fabric moves away from under the supporting inner wheel 8, it will become relaxed. After the fabric moves a certain distance, the pressing cylinder 4 is lifted again and the cylinder 12 is pushed to drive the adjusting push fork 13 to retract, and then the above steps are repeated, so that the equipment can continuously tighten the fabric. The device will not affect the winding and forward speed of the fabric while effectively eliminating the stress of the fabric, and can ensure production efficiency.

[0027] Leakage holes 33 are respectively provided on the support frame 2, a U-shaped frame 26 is installed on the top outer wall of the support frame 2, a downward pressure cylinder 27 is installed on the top outer wall of the U-shaped frame 26, the output end of the downward pressure cylinder 27 is connected to the water squeezing pressure plate 28, and a guide shaft 23 is installed on the top outer wall of the water squeezing pressure plate 28. The guide shaft 23 is movably connected with the U-shaped frame 26 and guided by the guide shaft 23, so that the water squeezing pressure plate 28 moves up and down more smoothly. After the fabric comes out from under the supporting inner wheel 8, it enters under the water squeezing pressure plate 28, and then the water squeezing pressure plate 28 is driven by the downward pressure cylinder 27 to press down the fabric, so that the moisture in the fabric can be squeezed out during the movement of the fabric, and the water flows out from the leakage holes 33, thereby improving the efficiency of subsequent drying.

[0028] An oven 29 is installed on the top outer wall of the support frame 2, and a heating box 30 is arranged inside the oven 29. A heating wire is arranged inside the heating box 30, and air outlets are respectively opened at the bottom of the heating box 30. A blower 31 is arranged on the top outer wall of the fixed bottom plate 1, and the output end of the blower 31 is connected to the heating box 30. After the fabric moves out from under the water squeezing plate 28, it enters the oven 29, and air is blown into the heating box 30 by the blower 31, so that the air is heated by the heating wire inside the heating box 30 and then blown out from the air outlet at the bottom of the heating box 30, so as to dry the fabric inside the oven 29.

[0029] A support inclined plate 37 is installed on one side wall of the fixed bottom plate 1. A guide roller 38 is rotatably connected to the support inclined plate 37. After the fabric comes out of the oven 29, it is placed on the guide roller 38. The guide roller 38 guides and supports the fabric. Then the fabric is connected to the winding mechanism, and the winding mechanism pulls the fabric to move. A water receiving box 1 32 and a water receiving box 2 34 are installed on one side wall of the support frame 2. The water receiving box 1 32 can receive water flowing from the water leakage hole 33, and the water receiving box 2 34 can receive water dripping from the water outlet shell 21.

[0030] When in use, the rolled fabric is placed on the support sleeve 17, and the support main shaft 16 is clamped with the support side plate 15, and then the locking nuts at both ends of the support main shaft 16 are tightened, and then the fabric is placed under the water outlet shell 21. After the water outlet shell 21 is fitted with the fabric, the fixing nut on the support screw 18 is tightened to fix the position of the water outlet shell 21, and then the fabric is passed through the two pulling components 5 respectively, and then placed under the support inner wheel 8 and the squeezing pressure plate 28 in turn, and finally passed through the oven 29 and placed on the guide roller 38, and then The fabric is then connected to the winding mechanism. When the fabric is pre-shaped, the fabric is moved by the winding mechanism. At the same time, the hot water in the hot water tank 35 is pumped into the hollow water pipe 20 by the water pump 36. The hot water enters the water outlet shell 21 through the water outlet hole 22 on the hollow water pipe 20, and then flows out through the water outlet hole 22 on the water outlet shell 21 to moisten the fabric. The fabric moves along the water outlet shell 21 during the process of moving forward, so that the water flowing out of the water outlet shell 21 can penetrate the fabric more quickly. Therefore, it is no longer necessary to immerse the fabric in water. The problem of excessive moisture in the fabric causing subsequent drying troubles is avoided. The pressing cylinder 3 502 drives the pressing roller 505 to descend and press the fabric. The rotation speed of the driving motor 507 on the U-shaped frame 3 501 on the side close to the supporting frame 3 is slightly greater than the rotation speed of the driving motor 507 on the side close to the supporting side plate 15, so that the fabric can be tightened between the two driving rollers 506, which will not affect the subsequent winding. When the fabric moves out from between the two driving rollers 506, it will become relaxed, thereby eliminating the stress on the fabric. The U-shaped frame 7 is driven down by the pressing cylinder 4, so that the adjusting pull ring 9 can be close to the fabric, and then the adjusting push fork 13 is driven to move by the pushing cylinder 12, so that the adjusting push fork 13 can drive the adjusting pull ring 9 to move horizontally, thereby tightening the fabric horizontally. While tightening, the supporting inner wheel 8 can rotate, so that the fabric can continue to move forward, and will not affect the production speed. The device can eliminate the stress of the fabric without affecting the winding and forward speed of the fabric, thereby ensuring production efficiency.
