Description

A fabric spreading mechanism for a fabric inspection machine Technical Field

[0001] This utility model relates to the field of fabric testing technology, specifically a fabric spreading mechanism for a fabric inspection machine. Background Technology

[0002] Fabric inspection machines are specialized equipment used in the garment industry to inspect extra-large, double-width, and single-width fabrics such as cotton, wool, linen, silk, and synthetic fibers before production. The operating method involves providing the necessary hardware environment for inspection, continuously unfolding the fabric in sections, providing ample light, and having the operator visually observe or use the equipment to detect surface defects and color differences. However, existing fabric inspection machines lack effective fabric unfolding capabilities. During operation, the fabric often fails to unfold completely laterally, resulting in wrinkles or partial overlap. This reduces the effectiveness of the inspection, as wrinkles and overlaps may obscure defects and color differences, leading to missed detections and impacting the machine's efficiency. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this utility model provides a fabric spreading mechanism for a fabric inspection machine, which solves the technical problem of missed inspections due to fabric wrinkles or overlaps when using existing fabric inspection machines.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a fabric spreading mechanism for a fabric inspection machine, including a frame, a flattening mechanism installed on the top of the frame, a pad installed on the inner side of the frame below the flattening mechanism, and a tensioning component movably connected inside the frame;

[0005] The flattening mechanism includes a bracket fixed to the top of the frame, a motor mounted on the top of the bracket, a drive shaft fixed to the output shaft of the motor, and a smoothing component and a flattening component connected to the drive shaft.

[0006] Preferably, the smoothing assembly includes a turntable fixed to the bottom of the drive shaft, a swing arm hinged to the bottom of the turntable via a connecting rod, a smoothing plate fixed to the bottom of the swing arm, and one end of the swing arm rotatably connected to the bottom of the bracket via a rotating shaft.

[0007] Preferably, the leveling assembly includes a drive wheel fixedly connected to the drive shaft, the drive wheel being connected to a driven wheel via a belt, the driven wheel being fixedly connected to a connecting shaft, the connecting shaft being rotatably connected to the inner side of the bracket, a bevel gear one being fixedly connected to the bottom of the connecting shaft, a bevel gear two being meshed on one side of the bevel gear one, a leveling roller being fixedly connected to the bevel gear two, the leveling roller being rotatably connected to the inner side of the frame, and two sets of symmetrically arranged auger blades being provided on the outer wall of the leveling roller.

[0008] Preferably, the frame is rotatably connected with guide roller one, guide roller two, guide roller three and take-up roller, and the tensioning assembly is located between guide roller three and take-up roller.

[0009] Preferably, the tensioning assembly includes a tensioning roller, both ends of which are rotatably connected to sliders. The sliders are slidably disposed in sliding holes opened on the side wall of the frame. A positioning post is fixed on the slider, and a counterweight ring is sleeved on the positioning post.

[0010] Preferably, a light panel is also installed on the frame.

[0011] By employing the above technical solution, this utility model provides a fabric spreading mechanism for a fabric inspection machine, which has at least the following beneficial effects:

[0012] 1. This fabric inspection machine uses a fabric spreading mechanism. By setting up a flattening mechanism, a motor drives the smoothing component and the flattening component to run. The smoothing component moves back and forth on the fabric surface through a smoothing plate, thereby flattening the fabric. Then, after the fabric passes through the flattening component, due to the two sets of auger blades symmetrically arranged on the flattening roller, the auger blades provide lateral tension to the fabric, thereby further flattening the fabric. This can solve the problem of missed inspections caused by wrinkles or partial overlaps on the fabric during the operation of the fabric inspection machine.

[0013] 2. The fabric inspection machine uses a fabric spreading mechanism. By setting up a tensioning component, the weight of the counterweight rings is used to make the tensioning roller exert downward pressure on the fabric, so that the fabric is in a taut state before winding, ensuring that the fabric is more neat and tight after winding. The tension can be adjusted by changing the number of counterweight rings. Attached Figure Description

[0021] 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.

[0022] Fabric inspection machines are mainly used in the textile, apparel, and home textile industries. In fabric manufacturing plants, they are used to inspect the quality of the produced fabrics. In garment processing plants, they can inspect the purchased fabrics before cutting and sewing to ensure the quality of the finished garments.

[0023] Example 1:

[0024] Based on the technical defects of existing technologies, such as missed detection of fabrics due to wrinkles or overlaps, please refer to Figures 1-4. This embodiment provides a fabric spreading mechanism for a fabric inspection machine, which can solve the problem of missed detection caused by wrinkles or partial overlaps in the fabric during operation. The mechanism includes a frame 1, a flattening mechanism 3 installed on the top of the frame 1, and a pad 4 installed on the inner side of the frame 1 below the flattening mechanism 3. A tensioning component 7 is also movably connected inside the frame 1. In use, the fabric is conveyed along the inner side of the frame 1. Under the action of the flattening mechanism 3, the fabric can be fully spread out, avoiding the problem of missed detection caused by wrinkles or folds in the fabric.

[0025] Existing fabric inspection machines often experience issues with fabric not fully unfolding laterally during operation, resulting in wrinkles or partial overlap. This reduces the effectiveness of the inspection. To address this problem, please refer to Figure 2. The flattening mechanism 3 includes a support 301 fixed to the top of the frame 1. A motor 302 is mounted on the top of the support 301, and a drive shaft 303 is fixed to the output shaft of the motor 302. A smoothing component 304 and a flattening component 305 are connected to the drive shaft 303. The motor 302 drives the smoothing component 304 and the flattening component 305. The smoothing component 304 moves back and forth on the fabric surface via a smoothing plate 3044, thus flattening the fabric. After passing through the flattening component 305, the fabric is further flattened.

[0026] Furthermore, to achieve smooth fabric flattening, please refer to Figure 2. The smoothing assembly 304 includes a turntable 3041 fixed to the bottom of the drive shaft 303. A swing rod 3043 is hinged to the bottom of the turntable 3041 via a connecting rod 3042. A smoothing plate 3044 is fixed to the bottom of the swing rod 3043. One end of the swing rod 3043 is rotatably connected to the bottom of the bracket 301 via a rotating shaft 3045. The flattening assembly 305 includes a drive wheel fixed to the drive shaft 303. 3051, the driving wheel 3051 is connected to the driven wheel 3053 via belt 3052. The driven wheel 3053 is fixed to the connecting shaft 3054. The connecting shaft 3054 is rotatably connected to the inner side of the bracket 301. A bevel gear 3055 is fixed to the bottom of the connecting shaft 3054. A bevel gear 3056 meshes with one side of the bevel gear 3055. A flattening roller 3057 is fixed to the bevel gear 3056. The flattening roller 3057 is rotatably connected to the frame 1. On the inner side, two sets of symmetrically arranged auger blades 3058 are provided on the outer wall of the flattening roller 3057; when the motor 302 drives the drive shaft 303 to rotate, the drive shaft 303 can drive the turntable 3041 to rotate, the turntable 3041 drives the swing rod 3043 to move through the connecting rod 3042, the swing rod 3043 drives the smoothing plate 3044 to move, thereby smoothing the wrinkles on the surface of the fabric. Then, after the fabric passes through the flattening assembly 305, the active wheel 3051 and the driven wheel 3058 are connected. Under the transmission action of 53, the connecting shaft 3054 can be rotated. The connecting shaft 3054 drives the flattening roller 3057 to rotate through the meshing action of bevel gear 1 3055 and bevel gear 2 3056. Due to the two sets of auger blades 3058 symmetrically arranged on the flattening roller 3057, the auger blades 3058 provide a pulling force to both sides on the fabric, thereby further flattening the fabric. This can solve the problem of missed inspection caused by wrinkles or partial overlap on the fabric when the fabric inspection machine is working.

[0027] Furthermore, within the frame 1, guide roller 1 2, guide roller 2 5, guide roller 3 6 and take-up roller 8 are rotatably connected, and tensioning assembly 7 is located between guide roller 3 6 and take-up roller 8; the fabric can be gradually unfolded using guide roller 1 2, guide roller 2 5 and guide roller 3 6 to facilitate the detection of defects on the fabric, and after detection, it can be rewound by take-up roller 8.

[0028] After the fabric inspection is completed, the fabric needs to be rewound. However, the fabric is prone to loosening during rewinding, which makes subsequent storage and transportation inconvenient. To address this issue, please refer to Figure 4. The tensioning assembly 7 includes a tensioning roller 704, with sliders 701 rotatably connected to both ends of the tensioning roller 704. The sliders 701 are slidably disposed in sliding holes opened on the side wall of the frame 1. A positioning post 702 is fixed on the slider 701, and a counterweight ring 703 is sleeved on the positioning post 702. The weight of the counterweight ring 703 itself causes the tensioning roller 704 to exert downward pressure on the fabric, thereby keeping the fabric taut before rewinding. This ensures that the fabric is more neat and compact after rewinding, and the tension can be adjusted by changing the number of counterweight rings 703.

[0029] Furthermore, a light panel 9 is also installed on the frame 1; the light panel 9 illuminates the fabric from the back, making the defects on the fabric more obvious, so as to facilitate subsequent inspection.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
