Description

Technical Field

[0001] This utility model relates to the field of pre-shrinking technology in textile fabric production, and in particular to a pre-shrinking machine for textile fabric production. Background Technology

[0002] During the production of textile fabrics, fibers are subjected to stretching and thermal stress during weaving and dyeing, making them prone to shrinkage and deformation during subsequent processing or use, affecting the quality of the finished product. As a key piece of equipment in textile finishing, the pre-shrinking machine is mainly used to pre-shrink the fabric to stabilize its dimensions and reduce shrinkage problems during subsequent use. Traditional pre-shrinking machines usually use methods such as steam heating and mechanical extrusion to shrink the fabric. However, the efficiency and adaptability of the winding and guiding structure directly affect production efficiency and fabric processing results. With the textile industry's increasing demand for production automation and high efficiency, how to optimize the winding and guiding mechanism of the pre-shrinking machine so that it can be quickly disassembled and adapted to fabrics of different sizes has become a technical problem that needs to be solved.

[0003] Existing pre-shrinking machines typically employ a fixed take-up roller structure, which is driven by a motor to rotate the take-up roller so that the fabric is wound evenly. In addition, the take-up roller is usually disassembled by bolt fixing or pin connection, requiring manual disassembly and assembly using tools.

[0004] Existing preshrinking machines typically use fixed connections for their take-up rollers, such as bolt fastening or pin locking. This makes disassembly cumbersome after the rollers have been wound to their maximum extent, requiring manual loosening of each fastener with tools, which is time-consuming. This not only reduces production efficiency but can also lead to equipment wear or personnel injury due to improper operation. Therefore, a preshrinking machine for textile fabric production is proposed to solve the above problems. Utility Model Content

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A pre-shrinking machine for textile fabric production includes a support frame, a traction platform on one side of the support frame, a pre-shrinking chamber on the top of the support frame, multiple conveying rollers inside the support frame, all of which are rotatably connected inside the support frame, a limiting ring fixedly connected to the side wall of the traction platform, a take-up roller rotatably connected inside the limiting ring, a motor fixedly connected to the top of the traction platform, a threaded cylinder fixedly connected to the output end of the motor, a slot being provided inside the threaded cylinder, and a disassembly assembly being provided on the outer wall of the take-up roller. The disassembly assembly includes a threaded sleeve and a retaining pin. The threaded sleeve is slidably connected to the outer wall of the take-up roller, and the retaining pin is fixedly connected to the inside of the take-up roller. The inner wall of the threaded sleeve is threadedly connected to the outer wall of the threaded cylinder, and the outer wall of the retaining pin is slidably connected to the inner wall of the retaining groove. A guide assembly is provided inside the bracket.

[0007] The above technical solution achieves the effect of disassembling the take-up roller.

The first sliding rod is slidably connected inside the bracket, the second sliding rod is slidably connected inside the bracket, and the bottoms of the plurality of guide rollers are all fixedly connected to the tops of the first sliding rod and the second sliding rod.

[0009] The above technical solution achieves the effect of guiding the fabric.

[0010] Preferably, a slide rail is fixedly connected inside the bracket, and both the first slide rod and the second slide rod are slidably connected to the top of the slide rail.

[0011] The above technical solution enables the transmission component to achieve the effect of limiting sliding.

[0012] Preferably, a rack two is fixedly connected to the inner wall of the sliding rod one, and a rack one is fixedly connected to the inner wall of the sliding rod two.

[0013] The above technical solution achieves the purpose of mechanical force transmission.

[0014] Preferably, both the sliding rod one and the sliding rod two have limiting grooves inside, and both the rack one and the rack two are slidably connected inside the limiting grooves.

[0015] The above technical solution enables the transmission component to slide within a preset range.

[0016] Preferably, the bracket has multiple limiting frames fixedly connected inside, and both rack one and rack two are slidably connected inside the multiple limiting frames.

[0017] The above technical solution aims to prevent displacement of the transmission components.

[0018] Preferably, the bracket is rotatably connected with gears, and all gears mesh with rack one and rack two.

[0019] The above technical solution achieves the effect of converting rotational motion into linear motion.

[0020] Preferably, a second motor is installed inside the bracket, the bottom of the second motor is fixedly connected to the top of the pre-shrinking chamber, and the gear is fixedly connected to the output end of the second motor.

[0021] The above technical solution ensures that the output end is fixedly installed inside the device.

[0022] This utility model has the following beneficial effects: 1. In this utility model, by rotating the threaded sleeve, the threaded sleeve is disengaged from the threaded cylinder. Then, the take-up roller is pulled, and the take-up roller slides out from inside the threaded cylinder. At the same time, the locking pin slides out from inside the locking groove. Then, the take-up roller drives the threaded sleeve and the locking pin to slide out from inside the limiting ring, thereby achieving the effect of quickly disassembling the take-up roller of the pre-shrinking machine. This solves the problem that the take-up roller of the pre-shrinking machine occupies space when it is wound to the maximum extent, making it impossible to quickly unload and collect materials, and improves the material unloading and collection efficiency of the pre-shrinking machine.

[0023] 2. In this utility model, the output end of motor 2 rotates to drive rack 1 and rack 2 to slide inside the limiting frame. Rack 1 and rack 2 drive sliding rod 1 and sliding rod 2 to move relative to each other. At the same time, sliding rod 1 and sliding rod 2 are limited to slide, thereby achieving the effect of guiding fabrics of different sizes to the center during the conveying process. This solves the problem that fabrics of different sizes are prone to edge deviation and deviation during conveying, which leads to uneven subsequent winding and processing obstruction, and improves the stability of the pre-shrinking process.

A guide assembly is provided inside the bracket 1. The guide assembly is used to adjust the fabric conveying path and prevent deviation.

[0028] Reference Figure 4 and Figure 5The guiding assembly includes a sliding rod 15, a sliding rod 16, and multiple guide rollers 4. Sliding rod 15 drives one side of the guide roller 4 to move and maintain stability, while sliding rod 16 drives the other side of the guide roller 4 to move and maintain symmetry. The multiple guide rollers 4 guide the fabric direction and prevent deviation. Sliding rod 15 and sliding rod 16 are slidably connected inside the bracket 1. The bottoms of the multiple guide rollers 4 are fixedly connected to the tops of sliding rod 15 and sliding rod 16.

[0029] Working principle: When it is necessary to collect the rolled-up fabric, the threaded sleeve 9 on the outer wall of the threaded cylinder 8 is rotated to disengage the threaded sleeve 9 from the threaded cylinder 8. Then, the take-up roller 5 is pulled out from the inside of the threaded cylinder 8 by sliding the take-up roller 5. At the same time, the take-up roller 5 drives the threaded sleeve 9 and the slot 11 to slide out from the inside of the limiting ring 7. Meanwhile, the locking post 10 slides out from the inside of the slot 11, thereby separating the take-up roller 5 from the traction platform 2 and collecting the fabric. This achieves the purpose of quickly unloading the rolled-up fabric. When pre-shrinking fabrics of different sizes, the output of motor 12 drives rack 19 to rotate. When rack 19 rotates, it drives racks 18 and 19 to slide. At the same time, racks 18 and 19 slide within the limiting frame 20. The displacement of racks 18 and 19 drives sliding rods 15 and 16 to slide relative to each other on the slide rail 14, moving synchronously towards the center of the bracket 1. This also drives the guide roller 4 above to move synchronously, thus achieving the purpose of centering and guiding fabrics of different sizes.
