Description

Technical Field

[0001] The present application relates to the technical field of fabric smoothing, and in particular to a smoothing device for producing high-elastic double-sided crepe yarn-dyed fabrics. Background Art

[0002] In the textile industry, fabric smoothing is an important step, especially for high-quality fabrics such as high-elastic double-sided crepe yarn-dyed fabrics.

[0003] Existing fabric flattening devices mainly use a single flattening method to flatten the fabric. The specific means include using a single or multiple pairs of pressure rollers to directly apply pressure to the fabric, so that the fabric becomes relatively flat after passing through the pressure rollers. In addition, some devices use gravity or other auxiliary equipment to flatten the fabric. Although these methods can play a certain flattening role, they still have certain limitations in actual application.

[0004] Regarding the above-mentioned related technologies, for highly elastic fabrics, the existing flattening devices often cannot effectively prevent the occurrence of fabric rebound and wrinkling during the processing process, resulting in poor overall flattening effect; and, frequent manual adjustments are required during the operation, increasing production and time costs. Summary of the invention

[0005] In order to improve the flatness of fabrics and reduce the wrinkling of fabrics, the present application provides a flattening device for producing high-elastic double-sided crepe yarn-dyed fabrics.

[0006] The present application provides a flattening device for producing high-elastic double-sided crepe yarn-dyed fabrics, which adopts the following technical solution: A flattening device for producing high-elastic double-sided crepe yarn-dyed fabrics, comprising a frame, a transmission component, a first flattening component and a first driving component; The conveying assembly is installed on the frame, and the conveying assembly includes a conveyor belt and two conveyor rollers. The two conveyor rollers are parallel to each other and parallel to the first direction. The two conveyor rollers are spaced apart along the second direction, and the second direction is perpendicular to the first direction. The conveyor rollers are rotatably connected to the frame, and the conveyor rollers are parallel to the first direction along the rotation axis of the frame. The conveyor belt is wound around the two conveyor rollers, and one side of the conveyor belt is a feed port, and the other side is a discharge port. The first driving assembly is used to drive the conveying roller to rotate; The first flattening component is arranged above the conveyor belt, and the first flattening component includes a first flattening piece and an auxiliary flattening piece. The first flattening piece is directly or indirectly connected to the frame, the first flattening piece includes a first flattening plane, and an auxiliary flattening piece is provided at each end of the first flattening piece. The auxiliary flattening piece includes a second flattening plane, and a side of the first flattening plane close to the conveyor belt is flush with a side of the second flattening plane close to the conveyor belt, and the auxiliary flattening piece is slidably connected to the first flattening plane along a first direction.

[0007] By adopting the above technical solution, since the high elastic fabric may be wrinkled or uneven during transportation, a first flattening member is set, and the fabric is transported from the feed port to the discharge port on the conveyor belt. When the fabric passes through the first flattening member, the first flat surface of the first flattening member flattens the fabric. If wrinkles are generated in the middle of the fabric, the wrinkled part in the middle of the fabric will be extended to both sides during the process of flattening the fabric by the first flattening member. In order to avoid the warping or bulging of the fabric on both sides, an auxiliary flattening member is set. The two auxiliary flattening members slide along the first direction, so that the auxiliary flattening members can smooth both sides of the fabric during the sliding process, and the auxiliary flattening members can flatten the fabric at the same time, thereby further improving the flatness of the fabric and reducing the wrinkling of the fabric.

[0008] Optionally, it further comprises a second driving assembly for driving the auxiliary flattening member to slide along the first direction, wherein the second driving assembly comprises a first mounting seat, a screw rod and a second motor; The first mounting seat is connected to the frame, the screw rod is parallel to the first direction, and the screw rod is passed through and rotatably connected to the first mounting seat; The auxiliary flattening piece is threadedly connected to the screw rod, the first flattening piece is connected to the screw rod via a bearing, and the thread directions of the screw rod at the two auxiliary flattening pieces are opposite; The housing of the second motor is fixedly connected to the first mounting seat, and the output shaft of the second motor is coaxially fixedly connected to the screw rod.

[0009] By adopting the above technical solution, in order to guide the sliding of the auxiliary flattening member along the first direction, a second driving assembly is set, and the second motor drives the screw to rotate. Since the first flattening member is connected to the screw through a bearing, the first flattening member does not rotate with the rotation of the screw. The rotation of the screw drives the two auxiliary flattening members to slide back and forth along the first direction, and the second flattening surfaces of the two auxiliary flattening members flatten the fabric.

[0010] Optionally, it also includes a second flattening component, which is arranged on a side of the first flattening component close to the discharge port, and the second flattening component includes a first flattening roller, which is parallel to the first direction and is rotatably connected to the frame through a second mounting seat.

[0011] By adopting the above technical solution, in order to further flatten the fabric, a second flattening component is set up, and the second flattening component includes a first flattening roller. The first flattening roller further flattens the fabric, and because the first flattening roller is rotatably arranged on the frame, in conjunction with the transportation of the conveyor belt, that is, when the fabric passes through the first flattening roller, the fabric can pass in a natural state rather than a pulled state, and the first flattening roller flattens the fabric for a second time.

[0012] Optionally, a heating ring is provided inside the second flattening roller.

[0013] By adopting the above technical solution, a heating ring is arranged in the second flattening roller. During the transportation of the fabric, the heating ring transfers heat to the fabric through the second flattening roller to iron the fabric, thereby further improving the flatness of the fabric.

[0014] Optionally, a fixing piece is fixedly connected to a side of the first mounting seat close to the discharge port, and a plurality of nozzles are fixedly connected to a side of the fixing piece close to the conveyor belt.

[0015] By adopting the above technical solution, when the fabric is ironed under the heating action of the heating ring, in order to avoid the fabric being damaged by excessive temperature or scorch marks on the surface of the fabric, a fixing piece is provided, and a plurality of nozzles are provided on the fixing piece. After the fabric passes through the first flattening piece, the nozzles spray water on the fabric. After the soaked fabric passes through the first flattening roller, the heat generated by the heating ring evaporates the moisture on the surface of the fabric, further reducing the heat of the heating ring, thereby avoiding damage to the inside of the fabric.

[0016] Optionally, the fixing member includes a first connecting part and a second connecting part, one end of the first connecting part is fixedly connected to the first mounting seat, and the other end is connected to the second connecting part, the nozzle is arranged on the first flattening part, and the second connecting part is inclined toward the side close to the conveyor belt along the direction from the feed port to the discharge port.

[0017] By adopting the above technical solution, when the nozzle sprays water on the fabric, the first connecting part and the second connecting part are set, and the second connecting part is set obliquely. The inclined second connecting part blocks the water splashed on the fabric by the nozzle, thereby reducing excessive wetting of the fabric.

[0018] Optionally, a second flattening roller is rotatably connected to a side of the second connecting portion close to the conveyor belt, and the second flattening roller is parallel to the first direction.

[0019] By adopting the above technical solution, a second flattening roller is arranged on the second connecting part, and the second flattening roller flattens the soaked fabric for the first time, and the second flattening roller can squeeze out excess water on the fabric to prevent the fabric from being over-soaked.

[0020] Optionally, the first flattening member is slidably connected to the frame along a third direction.

[0021] By adopting the above technical solution, due to the difference in fabric thickness, in order to make the first flattening member come into close contact with the fabric, the first flattening member is slidably connected to the frame along the third direction so that the first flattening member comes into close contact with the fabric to achieve a better flattening effect.

[0022] Optionally, a third drive assembly is also included, which includes a third mounting seat, a fixing member and a cylinder, the third mounting seat is fixedly connected to the frame, the fixing member is fixedly connected to the first mounting seat and the second mounting seat, the cylinder housing is fixedly connected to the third mounting seat, the extension and retraction direction of the cylinder piston rod is parallel to the third direction, and the cylinder piston rod is directly or indirectly connected to the fixing member.

[0023] By adopting the above technical solution and setting a third driving assembly, the cylinder drives the first mounting seat to slide along the third direction, further driving the first flattening member and the first flattening roller to slide along the third direction, so as to adjust the distance between the first flattening member, the first flattening roller and the fabric, so that the first flattening member and the first flattening roller can adapt to fabrics of different thicknesses.

[0024] Optionally, the third driving assembly further comprises an elastic member, the expansion and contraction direction of the elastic member is parallel to the third direction, and the elastic member is fixedly connected between the fixing member and the cylinder piston rod. By adopting the above technical solution, since the fabric may be uneven, in this case, in order to ensure the smooth transportation of the fabric, an elastic member is provided. Under the action of the elastic member, the first flattening member flattens the fabric. If the fabric is uneven, the first flattening member can float in the third direction to ensure the smooth transportation of the fabric.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. The present application sets a first flattening member and an auxiliary flattening member. If wrinkles are generated in the middle of the fabric and the first flattening member flattens the fabric, the two sides of the fabric will extend, and curling, warping or bulging may occur. By setting auxiliary flattening members on both sides of the first flattening member, the auxiliary flattening members slide along the first direction to flatten and smooth the fabric on both sides, thereby further improving the flatness of the fabric; 2. The present application provides a second flattening roller and a heating ring, so that the first flattening roller flattens the fabric for the second time, and the heating ring heats and irons the fabric through the first flattening roller, so as to further improve the flatness of the fabric; 3. The present application sets a nozzle and a second flattening roller, wherein the nozzle wets the fabric to disperse the heat of the heating ring, thereby reducing the heating ring from scalding the fabric or causing scorch marks on the fabric surface, and the second flattening roller squeezes out excess water on the fabric.

The pulley 41 further drives the conveyor roller 22 to rotate. Under the rotation of the conveyor roller 22, the conveyor belt 21 is further driven to slide along the frame 1 to transport the fabric. Reference Figure 1 During transportation, for highly elastic fabrics, wrinkles may appear on the fabrics. In order to further flatten the fabrics, a first flattening assembly 3 is arranged above the conveyor belt 21. The first flattening assembly 3 includes a first flattening member 31 and an auxiliary flattening member 32. The first flattening member 31 is connected to the frame 1. The first flattening member 31 includes a first flattening plane 311. The first flattening plane 311 of the first flattening member 31 contacts the fabrics to flatten the fabrics. Reference Figure 1 If wrinkles are generated in the middle of the fabric, the wrinkles in the middle of the fabric will be extended to both sides during the process of flattening the fabric by the first flattening member 31.

The housing of the second motor 53 is fixedly connected to the first mounting seat 51, and the output shaft of the second motor 53 is coaxially fixedly connected to the screw 52. The second motor 53 drives the screw 52 to rotate, and the screw 52 drives the two auxiliary flattening members 32 to slide back and forth along the rod length direction of the screw 52, ​​so that the two auxiliary flattening members 32 flatten the two sides of the fabric.
