Description

Technical Field

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

[0002] Woven fabric is a fabric formed by interlacing warp and weft yarns. Common materials include cotton, polyester, and nylon. It is made using plain weave, twill weave, or satin weave processes. Its structure is compact and has the characteristics of wear resistance, breathability, and tensile strength. Fabric spreading machines are automated equipment in textile processing, used to lay out and position rolls of fabric flat for subsequent cutting.

[0003] The pile on the surface of woven fabric is formed by fiber breakage or friction shedding. Static electricity adsorption exacerbates dust accumulation, affecting the appearance and texture and reducing the product grade. In addition, pile accumulation may affect the uniformity of printing and dyeing, weaken the protective effect of functional coatings, and pose a potential risk to precision industrial applications. To address these issues, we propose a fabric spreading machine for garment production. Utility Model Content

[0004] The purpose of this utility model is to address the problems existing in the background technology by proposing a fabric spreading machine for garment production.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A fabric spreading machine for garment production includes a conveying roller, a fixed frame, a mounting plate, a tension roller, a first motor, a support plate, and a second motor. A support roller is rotatably mounted inside the fixed frame. Mounting plates are provided on both the front and rear sides of the support roller. A tension roller is rotatably mounted inside the mounting plate. Woven fabric is conveyed between the tension roller, the support roller, and the conveying roller. A collection box is provided below the support plate. A fan is provided at one end of the collection box, and a suction pipe is provided at another end of the collection box. A negative pressure box fitted onto the outside of the woven fabric is provided at one end of the suction pipe. A negative pressure port is opened on the inner wall of the negative pressure box. A frame is fixed on one side above the support plate. A second motor is provided at one end of the frame. A rotating shaft rotatably mounted inside the frame is provided at the output end of the second motor. Equally spaced springs are provided at the upper end of the frame. A limit ring is provided at the upper end of each spring, and a guide rod passes through the limit ring.

[0006] Preferably, the frame is internally fitted with equally spaced sliding sleeves, and the lower end of the guide rod is slidably inserted into the sliding sleeve. The guide rod receives sliding support inside the sliding sleeve and sliding guidance inside the support plate.

[0007] Preferably, the outer wall of the rotating shaft is provided with a protrusion, and a ball bearing is rotatably mounted on the lower end of the guide rod. When the rotating shaft rotates, it causes the protrusion to pass through the guide rod, which applies a compressive force to the guide rod. At the same time, it applies a compressive force to the spring, and the ball bearing reduces the resistance and friction as the protrusion passes through.

[0008] Preferably, a sleeve frame is fixed on one side above the support plate, and both ends of the sleeve frame have travel openings for fitting onto the outside of the woven fabric. The upper end of the guide rod is fitted with the lower end of the sleeve frame. During the conveying process, the woven fabric passes effectively through the travel openings at both ends of the sleeve frame.

[0009] Preferably, guide rollers are rotatably mounted on the inner walls of both the upper and lower ends of the travel opening. When the woven fabric passes through the travel opening, it rotates and fits against the outer wall of the guide rollers, reducing friction and resistance as the woven fabric passes through. The guide rod, supported by the elastic force of the spring, impacts the lower end of the sleeve frame.

[0010] Preferably, an installation shaft is rotatably mounted on the upper end of the support plate, and a rubber scraper is provided on the upper end of the installation shaft. A torsion spring is sleeved between the rubber scraper and the support plate, extending outward from the installation shaft. The rubber scraper receives rotational support through the installation shaft. When the installation shaft rotates, it applies a torsional force to the torsion spring. When the woven fabric passes through the rubber scraper, it drives the installation shaft to rotate. Furthermore, because the rubber scraper is supported by the torsional force of the torsion spring, it applies a force opposite to that applied when the woven fabric passes through, thus smoothing out the wrinkles in the woven fabric.

[0011] Preferably, the inner wall of the collection box is equipped with a filter screen, and the lower end of the collection box is equipped with a discharge pipe, the discharge pipe having a valve inside. Dust entering the collection box is sucked in, intercepted by the filter screen to prevent dust from entering the fan, and the dust inside the collection box is discharged through the discharge pipe, the opening and closing of which is controlled by the valve.

[0012] Preferably, a motor is mounted at one end of the fixing frame, and a gear is mounted at one end of the motor. Adjusting shafts, rotatably mounted inside the fixing frame, are mounted on the inner wall of the mounting plate. A gear, meshing with gear one, is sleeved on the outer wall of each adjusting shaft. When the motor operates, it drives gear one to rotate, which in turn drives the adjusting wheel to rotate, thereby rotating the mounting plate and tension roller around the adjusting shafts, applying different tensions to the woven fabric.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model involves conveying the woven fabric between a support roller, a tension roller, and a conveying roller. During the conveying process, the tension roller adjusts the tension of the woven fabric to maintain tension during the conveying process. As the woven fabric is continuously conveyed, it vibrates at high frequency. The vibration causes the fibers on the outer wall of the woven fabric to fall off. Subsequently, a negative pressure structure is used for dust removal, which cleans the outer wall of the woven fabric and removes excess fibers, improving the appearance quality of the woven fabric and facilitating subsequent processing and winding.

[0023] like Figures 1-6As shown, this utility model proposes a fabric spreading machine for garment production, including a conveying roller 1, a fixed frame 3, a mounting plate 5, a tension roller 6, a first motor 8, a support plate 11, and a second motor 31. A support roller 4 is rotatably mounted inside the fixed frame 3. Mounting plates 5 are provided on both the front and rear sides of the support roller 4. A tension roller 6 is rotatably mounted inside the mounting plate 5. Woven fabric 2 is conveyed between the tension roller 6, the support roller 4, and the conveying roller 1. A collection box 12 is provided below the support plate 11, and a fan 2 is provided at one end of the collection box 12. 5. A suction tube 26 is provided at one end of the collection box 12. A negative pressure box 13 is provided at one end of the suction tube 26 and is sleeved on the outside of the woven fabric 2. A negative pressure port 27 is provided on the inner wall of the negative pressure box 13. A frame 17 is fixed on one side above the support plate 11. A motor 31 is provided at one end of the frame 17. A rotating shaft 22 is rotatably installed inside the frame 17 at the output end of the motor 31. Springs are evenly distributed at the upper end of the frame 17. A limit ring 19 is provided at the upper end of the springs. A guide rod 18 passes through the inside of the limit ring 19.

[0024] The frame 17 is embedded with equally spaced sliding sleeves 20, and the lower end of the guide rod 18 is slidably inserted into the sliding sleeve 20.

[0025] The outer wall of the rotating shaft 22 is provided with a protrusion 23, and a ball bearing 21 is rotatably installed at the lower end of the guide rod 18;

[0026] A sleeve frame 16 is fixed on one side above the support plate 11. Both ends of the sleeve frame 16 are provided with travel openings 15 that fit onto the outside of the woven fabric 2. The upper end of the guide rod 18 is attached to the lower end of the sleeve frame 16.

[0027] Guide rollers 28 are rotatably installed on the inner walls of both the upper and lower ends of the stroke port 15.

[0028] A mounting shaft 29 is rotatably mounted on the upper end of the support plate 11. A rubber scraper 14 is provided on the upper end of the mounting shaft 29. A torsion spring 30 is sleeved on the mounting shaft 29 between the rubber scraper 14 and the support plate 11.

[0029] The inner wall of the collection box 12 is equipped with a filter screen 24, and the lower end of the collection box 12 is equipped with a discharge pipe, and a valve is installed inside the discharge pipe;

[0030] One end of the fixed frame 3 is equipped with a motor 8, and the other end of the motor 8 is equipped with a gear 9. The inner wall of the mounting plate 5 is equipped with an adjusting shaft 10 that is rotatably installed inside the fixed frame 3. The outer wall of the adjusting shaft 10 is sleeved with a gear 7 that meshes with the gear 9.

[0031] Based on the implementation steps of Example 1: First, start motor 8 to drive gear 9 to rotate, which drives adjustment shaft 10 and gear 7 to make mounting plate 5 rotate around adjustment shaft 10, adjust the pressing angle of tension roller 6 on woven fabric 2, and achieve tension adjustment through gear ring meshing to ensure that different materials of fabric maintain a constant tension during the conveying process. Then, start motor 31 to drive rotating shaft 22 to rotate, and protrusion 23 intermittently squeezes ball 21 at the lower end of guide rod 18, so that guide rod 18 forms high-frequency reciprocating motion in sliding sleeve 20, which drives limit ring 19 and spring system to generate periodic vibration waves. This vibration is transmitted to the surface of woven fabric 2 through sleeve frame 16, and its longitudinal vibration acceleration can efficiently separate attached lint and electrostatically adsorbed dust particles.

[0032] During the dust removal stage, the negative pressure box 13, through the negative pressure port 27, works in conjunction with the guide roller 28 to rotate and lift, and the negative pressure adsorption combined effect, so that the shed lint and dust enter the collection box 12 through the suction pipe 26. After being intercepted by the filter screen 24, they are periodically removed through the discharge valve. When the woven fabric 2 passes through the rubber scraper 14, the mounting shaft 29 rotates under the action of the fabric friction force, with a maximum rotation angle of 30°. The torsion spring 30 provides a reverse pre-tightening force, so that the scraper always maintains a dynamic contact of 0.1-0.3mm with the fabric surface, which effectively smooths out wrinkles without damaging the fiber structure.

[0033] The vibration peeling and negative pressure adsorption system removes the lint from the outer wall of the woven fabric 2, solving the problem of dust accumulation caused by electrostatic adsorption. The dynamic tension adjustment mechanism can adapt to different tension requirements, avoiding fabric stretching and deformation. The elastic scraper system eliminates wrinkles, ensuring the uniformity of subsequent printing and dyeing. A three-in-one processing module of vibration, adsorption and smoothing is constructed, making the equipment have multiple functions of cleaning, tension control and shaping. It is especially suitable for the pretreatment of woven fabric 2 for precision industrial use, which can significantly improve coating adhesion and extend the service life of functional fabrics.
