A weaving winding tensioning mechanism for polyester fabric production

Abstract

This utility model discloses a weaving and winding tensioning mechanism for polyester fabric production, relating to the technical field of tensioning mechanisms. The weaving and winding tensioning mechanism for polyester fabric production includes a support frame, with a winding mechanism positioned above the support frame for winding the polyester fabric. The winding mechanism includes a tension adjustment component positioned above the support frame for adjusting the tension of the polyester fabric. During winding, a winding motor drives a transmission disc to rotate, and the transmission disc transmits power to a transmission shaft via a transmission spring. When the damping of the transmission shaft changes due to the increase in the diameter of the paper roll, the deformation of the transmission spring changes accordingly. Pressure sensors at both ends of the spring can capture this pressure change in real time, obtaining the load condition of the transmission shaft. Based on the real-time data from the two pressure sensors, the control system drives an electric push rod to adjust the elongation, causing the pressure roller to change its relative height to the limit rod, thereby changing the tension of the polyester fabric and achieving real-time dynamic adjustment of tension during the winding process.

Description

Technical Field

[0001] This utility model relates to the field of tensioning mechanism technology, specifically a weaving winding tensioning mechanism for polyester fabric production. Background Technology

[0002] Polyester fabric, which is a fabric woven from polyester (chemical name: polyethylene terephthalate, PET), is one of the most widely used categories of synthetic fiber fabrics. With its excellent physical properties and cost-effectiveness, it has penetrated into many fields such as clothing, home textiles, and industry.

[0003] The existing utility model patent with publication number CN219929165U discloses a stretch film winding device with a tensioning mechanism. The device includes a housing with four casters fixedly mounted on its bottom surface. Two anti-winding devices are fixedly installed inside the housing. A control panel is fixedly mounted on the front of the housing, and a cutter is fixedly mounted on its top surface. A winding device is located below the cutter and is fixedly installed inside the housing. An auxiliary rotating rod is located on the left side of the winding device and is fixedly connected to the housing. This utility model, by incorporating anti-winding devices, prevents the stretch film from swaying during winding. If the edges of the stretch film are not folded during winding, it can cause large areas of the subsequent stretch film to fold. Therefore, during winding, the swaying of the stretch film causes the anti-winding strip to extend and retract within the extension groove via a telescopic block and a telescopic spring, preventing edge curling.

[0004] The aforementioned winding device cannot adjust the tension in real time according to the damping of the winding assembly during winding. As the roll diameter increases over time during winding, maintaining a constant tension will result in excessive stretching of the inner layer and loosening of the outer layer. Furthermore, a paper tube is generally required as the core during winding, and the aforementioned winding device cannot be quickly fitted onto the winding machine, affecting its efficiency. Utility Model Content

[0010] Preferably, the limiting rod and the support frame are rotatably connected, the guide column and the support frame are slidably connected, the center of the movable frame and the movable end of the electric push rod are fixedly connected, a pressure sensor is also provided at the connection between the bottom of the electric push rod and the movable frame, the pressure roller and the movable frame are rotatably connected, the center diameter of the pressure roller is larger than the two ends, and the whole is spindle-shaped.

[0011] Preferably, the transmission disk, transmission shaft, and support frame are all rotatably connected. One side of the transmission shaft is provided with a disc-shaped structure with the same size as the transmission disk. The disc-shaped structure of the transmission shaft fits into the transmission disk. The surfaces of the transmission disk and the disc-shaped structure of the transmission shaft are provided with openings for mounting transmission springs.

[0012] Preferably, the transmission spring has plate-like structures at both ends, and the two ends of the transmission spring are fixedly connected to the transmission disk and the transmission shaft respectively through pressure sensors.

The drive shaft is rotatably connected to the limiting block and the movable block.

[0014] Beneficial effects

[0015] This invention provides a weaving and winding tensioning mechanism for polyester fabric production. Compared with the prior art, it has the following advantages:

[0016] (1) The weaving and winding tensioning mechanism used in the production of polyester fabric involves a winding motor driving a transmission disc to rotate during winding. The transmission disc transmits power to the transmission shaft through a transmission spring. When the damping of the transmission shaft changes due to the increase in the diameter of the paper roll, the deformation of the transmission spring will change accordingly. The pressure sensors at both ends can capture this pressure change in real time and obtain the load status of the transmission shaft. At the same time, the pressure sensor at the connection between the electric push rod and the movable frame monitors the reaction force of the polyester fabric on the pressure roller, indirectly reflecting the current tension status. Based on the real-time data from the two pressure sensors, the control system drives the electric push rod to adjust the elongation. The electric push rod drives the movable frame to slide along the guide column, and the movable frame in turn drives the pressure roller to change its relative height with the limit rod. By adjusting the height difference between the two, the tension of the polyester fabric is changed, realizing the real-time dynamic adjustment of tension during the winding process, avoiding the problems of excessive stretching of the inner layer and loosening of the outer layer.

[0017] (2) The weaving and tensioning mechanism used in the production of polyester fabric allows for quick release of the movable block's limit by rotating the fixed rod during paper tube installation. After removing the movable block, pulling down the positioning block and compressing the limit spring allows the positioning block to disengage from the notch in the limit block, thus removing the limit block and freeing one end of the drive shaft from clamping. Subsequently, the limit plate on the outside of the drive shaft can be removed by rotating the threaded connection, providing sufficient space for paper tube installation. After the paper tube is installed, the limit plate, limit block, and movable block are reset by reversing the operation, and the fixed rod is rotated again to fix the movable block, completing the installation. Throughout the process, the limiting connection between the fixed rod and the movable block, the fitting connection between the positioning block and the limit block, and the threaded connection between the limit plate and the drive shaft greatly simplify the operation steps, eliminating the need for complex disassembly, making paper tube installation more convenient, and improving operational efficiency.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a weaving and winding tensioning mechanism for polyester fabric production includes a support frame 1, and a winding mechanism 2 is arranged above the support frame 1 for winding the polyester fabric. The winding mechanism 2 includes:

[0025] Tension adjustment component 21, located above support frame 1, is used to adjust the tension of polyester fabric. Tension adjustment component 21 includes a limiting rod 211 fixedly installed between support frames 1, and an electric push rod 212 on the top of support frame 1. A guide column 213 is inserted and installed above support frame 1. A movable frame 214 is fixedly installed at the bottom of guide column 213. A pressure roller 215 is movably installed below movable frame 214. The limiting rod 211 is rotatably connected to support frame 1, and the guide column 213 is slidably connected to support frame 1. The center of movable frame 214 is fixedly connected to the movable end of electric push rod 212. A pressure sensor 227 is also provided at the connection between the bottom of electric push rod 212 and movable frame 214. The pressure roller 215 is rotatably connected to movable frame 214. The center diameter of pressure roller 215 is larger than that at both ends, and the whole is spindle-shaped.

[0026] Specifically, the limiting rod 211 can limit the height of the polyester fabric. The electric push rod 212 drives the movable frame 214 to move downward, so that the pressure roller 215 installed at the bottom of the movable frame 214 and the limiting rod 211 are separated by a height difference, thereby adjusting the tension of the polyester fabric. The pressure sensor 227 between the electric push rod 212 and the movable frame 214 monitors the reaction force exerted by the polyester fabric on the pressure roller 215. The guide column 213 can limit the direction of movement of the movable frame 214.

[0027] The winding assembly 22 includes a winding motor 221 fixedly mounted on one side of the support frame 1. A transmission disc 222 is fixedly mounted at the end of the shaft of the winding motor 221. A transmission shaft 223 is inserted and mounted above the support frame 1. A sealing gasket 224 is fixedly mounted on one side of the transmission disc 222 and the transmission shaft 223. A limit disc 225 is threadedly mounted on the outside of the transmission shaft 223. A transmission spring 226 is fitted into one side of the transmission disc 222. Pressure sensors 227 are provided at both ends of the transmission spring 226. A positioning block 228 is provided above the support frame 1. A limit spring 229 is sleeved below the positioning block 228. A limit block 2210 is movably mounted above the support frame 1. A fixing rod 2211 is movably mounted above the limit block 2210. A movable block 2212 is fitted into the limit block 2210. The transmission disc 222, the transmission shaft 223, and the support frame 1 are all rotatably connected. A disc-shaped structure with the same size as the transmission disc 222 is provided. The disc-shaped structure of the transmission shaft 223 is in contact with the transmission disc 222. The surfaces of the disc-shaped structures of the transmission disc 222 and the transmission shaft 223 are provided with openings for the installation of the transmission spring 226. The two ends of the transmission spring 226 are provided with plate-shaped structures, and the two ends of the transmission spring 226 are fixedly connected to the transmission disc 222 and the transmission shaft 223 respectively through pressure sensors 227. The positioning block 228 is slidably connected to the support frame 1. The bottom of the limiting block 2210 is provided with a notch structure that fits into the positioning block 228. The movable block 2212 is slidably connected to the limiting block 2210. The fixed rod 2211 is rotatably connected to the limiting block 2210. The bottom surface of the movable block 2212 and the top surface of the limiting block 2210 form a cylindrical opening structure that fits into the transmission shaft 223. The transmission shaft 223 is rotatably connected to the limiting block 2210 and the movable block 2212.

[0028] Specifically, when the winding motor 221 drives the transmission disc 222 to rotate, the transmission disc 222 first compresses the transmission spring 226, and then the transmission spring 226 drives the transmission shaft 223 to rotate. The damping of the transmission shaft 223 during rotation is monitored by the pressure sensors 227 at both ends of the transmission spring 226, so that the electric actuator 212 can adjust the elongation according to the monitoring data of the pressure sensors 227 at both ends of the transmission spring 226 to control the tension of the polyester fabric. The positioning block 228 can limit the position of the limiting block 2210. When the movable block 2212 is fitted and installed above the limiting block 2210, the fixed rod 2211 can rotate... The method and the rod-shaped protrusion above the limiting block 2210 form a 90-degree structure, thereby restricting the position of the movable block 2212 and the limiting block 2210, so that the limiting block 2210 and the movable block 2212 can clamp one end of the drive shaft 223. When installing the paper tube, the movable block 2212 and the limiting block 2210 can be removed in sequence, so that the limiting plate 225 can be removed by rotation. Then, the paper tube is placed on the outside of the drive shaft 223. After the limiting plate 225 is reset, the limiting plate 225 can clamp the paper tube with the drive shaft 223. At the same time, the contents not described in detail in this specification are all prior art known to those skilled in the art.

[0029] During operation, the paper tube is installed first: rotate the fixed rod 2211 to release its restriction on the movable block 2212 and remove the movable block 2212; pull down the positioning block 228 to compress the limiting spring 229, so that the positioning block 228 is disengaged from the notch structure of the limiting block 2210 and the limiting block 2210 is removed; remove the limiting plate 225 on the outside of the drive shaft 223 by rotating the thread, put the paper tube on the drive shaft 223, reset the limiting plate 225 and fix it with the thread, then reset the limiting block 2210 and the movable block 2212 in sequence, rotate the fixed rod 2211 to form a 90-degree structure with the rod-shaped protrusion above the limiting block 2210, fix the movable block 2212, and complete the paper tube installation. Next, start the winding process: wrap one end of the polyester fabric around the top of the limiting rod 211, pass it under the pressure roller 215, and then around the top of the front limiting rod 211 to fix it on the paper tube; start the winding motor 221, which drives the transmission disc 222 to rotate. The transmission disc 222 compresses the transmission spring 226, and the transmission spring 226 transmits power to the transmission shaft 223 through the pressure sensors 227 at both ends. The transmission shaft 223 drives the paper tube to rotate and begin winding. Tension is adjusted in real time during winding: When winding, the increase in the diameter of the paper tube causes a change in the damping of the drive shaft 223, which in turn causes a change in the deformation of the drive spring 226. The pressure sensors 227 at both ends of the spring monitor the pressure change. At the same time, the pressure sensor 227 at the connection between the bottom of the electric push rod 212 and the movable frame 214 monitors the reaction force of the polyester fabric on the pressure roller 215. Based on the monitoring data of the two pressure sensors 227, the electric push rod 212 adjusts the elongation, which drives the movable frame 214 to slide up and down along the guide column 213. The movable frame 214 drives the pressure roller 215 to change the height difference with the limit rod 211, thereby adjusting the tension of the polyester fabric in real time to ensure the winding quality.
