Description

Technical Field

[0001] This utility model relates to the technical field of fabric laying devices, and in particular to a fabric laying device. Background Technology

[0002] During the fabric production process, a series of processing steps are required. Because fabric is relatively soft and has good stretchability, it needs to be laid flat during processing. To avoid wrinkles when the fabric is laid flat, which would affect subsequent processing, a special fabric flattening device is often used.

[0003] To address this, patent specification CN215828015U discloses a fabric flattening device, including a fixed frame, a moving strip, a steering clamp, a rubber brush, and a motor. The fixed frame has a column and a lead screw. One end of the moving strip is slidably connected to the column, and the other end is connected to the lead screw. The steering clamp is rotatably connected to the moving strip. The rubber brush is connected to the steering clamp. The motor is connected to one end of the moving frame and to the lead screw. The steering clamp has a positioning post. The purpose of this invention is to design a fabric flattening device that uses a motor to control the moving strip to flatten the fabric and a flexible rubber brush to improve the error tolerance, ensuring that the fabric can still be flattened on the production line, resulting in a smooth, fold-free finished fabric. While the above-mentioned fabric flattening device has a good flattening effect, some problems still exist:

[0004] 1. Because different specifications of fabrics have different thicknesses, it is often impossible to adjust the smoothing effect of the fabric according to its thickness when laying it out.

[0005] 2. Because the fabric is relatively soft, when the fabric is pulled and laid flat by the winding equipment, the tension of the fabric decreases during the pulling process, which can cause a lot of wrinkles to appear. Utility Model Content

[0006] The purpose of this invention is to provide a fabric flattening device to solve the problem that existing fabric flattening devices cannot be adjusted according to the thickness of the fabric.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a fabric laying device, including a support frame and a fixing plate, wherein an internally threaded slider is slidably connected inside the support frame, a fixing plate is fixedly connected to one side of the support frame, and an adjustment structure is fixedly connected to the top of the internally threaded slider. The adjustment structure includes a side frame, a drive rod, a guide plate, a bidirectional threaded groove, an internally threaded seat, a hinge rod, a bottom frame, a pressing cotton plate, and a buffer spring. The side frame is fixedly connected to the top of the internally threaded slider. Guide rollers are rotatably connected to the bottom ends of both sides of one end of the fixing plate. A tensioning structure is fixedly connected to the other end of the fixing plate. The tensioning structure includes an adjustment frame, a tensioning roller, a rotating shaft seat, a tensioning spring, an adjustment plate, and an adjustment screw. The adjustment frame is fixedly connected to the other end of the fixing plate.

[0008] In use, the device is installed on a designated platform, and the two sets of support frames are fixed on both sides of the platform. The fabric is passed through the guide rollers and tension rollers in sequence to be rolled up and pulled, and the fabric is laid on the inside of the two sets of support frames. Then, a motor drives the bidirectional screw inside one set of support frames, so that the internal thread slider drives the adjustment structure to move in the opposite direction, and in this way, the laid fabric is pressed flat by the pressing cotton board to prevent wrinkles.

[0009] Preferably, a drive rod is rotatably connected to the top of one end of the side frame, a guide plate is fixedly connected to the middle position of one end of the side frame, a bidirectional threaded groove is provided on the outer side of the drive rod, an internal threaded seat is sleeved on the outer side of the bidirectional threaded groove, a hinge rod is hinged to the bottom end of the internal threaded seat, a bottom frame is hinged to the bottom end of the hinge rod, a pressing cotton plate is slidably connected to the bottom end inside the bottom frame, and a buffer spring is fixedly connected to the top end of the pressing cotton plate.

[0010] Preferably, the bidirectional threaded grooves are evenly distributed on the outside of the drive rod, and the bidirectional threaded grooves are threadedly connected to the internal threaded seat, so as to press and flatten the fabric.

[0011] Preferably, the bottom frame and the pressing cotton plate have a sliding structure, and the buffer springs are evenly distributed at the top of the pressing cotton plate to avoid excessive pressing pressure that could damage the fabric.

[0012] Preferably, a tensioning roller is provided above the middle position of one end of the fixed plate, a rotating shaft seat is slidably connected inside the adjusting frame, a tensioning spring is fixedly connected to the bottom end of the rotating shaft seat, an adjusting plate is slidably connected to the lower part of the adjusting frame, and an adjusting screw passes through the bottom end of the adjusting frame.

[0013] Preferably, the adjustment frames are symmetrically distributed about the vertical center line of the tension roller, and the tension roller and the rotating shaft seat have a rotating structure, so as to make the fabric smoother when it is laid flat and stretched.

[0014] Preferably, the bottom end of the adjusting frame is threadedly connected to the adjusting screw, and the bottom end of the adjusting plate is rotating with the top end of the adjusting screw. This allows the fabric tension to be adjusted by pressing the tension spring with the adjusting plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are: by rotating the drive rod, the pressing pressure of the pressing cotton plate on the fabric is adjusted, and at the same time, the fabric is unfolded through the guide roller and the tension roller, and the tension is improved by the elastic support of the tension spring.

[0016] 1. By controlling the forward and reverse rotation of the drive rod, the hinge rod is raised and lowered to lift the bottom frame, so that the pressing cotton board can press and move the fabric to flatten it, and the elastic force of the buffer spring prevents excessive pressure from damaging the fabric.

[0017] 2. Since both ends of the tension roller extend into the interior of the rotating shaft seat, and the tension roller supports the fabric passing over the top of the tension roller under the elastic force of the tension spring, the adjusting plate can be pressed against the bottom of the tension spring by rotating the adjusting screw, thereby allowing the tension to be adjusted according to the flexibility of the fabric.

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.

[0025] Please see Figures 1-5 This utility model provides a fabric laying device, including a support frame 1 and a fixing plate 4. An internally threaded slider 2 is slidably connected inside the support frame 1. The fixing plate 4 is fixedly connected to one side of the support frame 1.

The side frame 301 is fixedly connected to the top of the internally threaded slider 2. The drive rod 302 is rotatably connected to the top of one end of the side frame 301. The middle of one end of the side frame 301... A guide plate 303 is fixedly connected to the position. A bidirectional threaded groove 304 is opened on the outer side of the drive rod 302. An internal threaded seat 305 is sleeved on the outer side of the bidirectional threaded groove 304. A hinge rod 306 is hinged to the bottom end of the internal threaded seat 305. A bottom frame 307 is hinged to the bottom end of the hinge rod 306. A pressing cotton plate 308 is slidably connected to the bottom end inside the bottom frame 307. A buffer spring 309 is fixedly connected to the top end of the pressing cotton plate 308. The bidirectional threaded groove 304 is evenly distributed on the outer side of the drive rod 302. The bidirectional threaded groove 304 and the internal threaded seat 305 are threadedly connected. The bottom frame 307 and the pressing cotton plate 308 are slidably connected. The buffer spring 309 is evenly distributed on the top end of the pressing cotton plate 308.

[0026] See attached document Figure 1 , Figure 2 and Figure 3 When using this device, since the thickness of different specifications of fabrics is not the same, after the fabric is laid flat, the motor connected to the bidirectional screw inside the support frame 1 is started, so that the screw rotates and drives the two sets of internal thread sliders 2 to move the adjustment structure 3 in the opposite direction, so that the pressing cotton plate 308 can flatten the fabric laid at the bottom. When the fabric is thick, the internal thread seats 305 that are threaded to the bidirectional thread groove 304 can be moved by rotating the drive rod 302. By controlling the forward and reverse rotation of the drive rod 302, the hinge rod 306 can be raised and lowered on the bottom frame 307, so that the pressing cotton plate 308 can press and move the fabric flat, and the elastic force of the buffer spring 309 can prevent excessive pressure from damaging the fabric.

[0027] The other end of the fixed plate 4 is fixedly connected to a tensioning structure 6. The tensioning structure 6 includes an adjusting frame 601, a tensioning roller 602, a rotating shaft seat 603, a tensioning spring 604, an adjusting plate 605, and an adjusting screw 606. The adjusting frame 601 is fixedly connected to the other end of the fixed plate 4. The tensioning roller 602 is provided above the middle position of one end of the fixed plate 4. The rotating shaft seat 603 is slidably connected inside the adjusting frame 601. The tensioning spring 604 is fixedly connected to the bottom end of the rotating shaft seat 603. The adjusting plate 605 is slidably connected to the lower part of the adjusting frame 601. The adjusting screw 606 passes through the bottom end of the adjusting frame 601. The adjusting frame 601 is symmetrically distributed about the vertical center line of the tensioning roller 602. The tensioning roller 602 and the rotating shaft seat 603 have a rotating structure. The interior of the bottom end of the adjusting frame 601 is threadedly connected to the adjusting screw 606. The bottom end of the adjusting plate 605 and the top end of the adjusting screw 606 have a rotating structure.

[0028] See attached document Figure 1 , Figure 4 and Figure 5 When this device is in use, because the fabric is relatively soft, it is easy to have a lot of wrinkles when it is laid out due to being too loose. Therefore, fixing plates 4 are fixed on both sides of the support frame 1, and the fabric passes through the guide roller 5 and the tension roller 602 in sequence. Since the two ends of the tension roller 602 penetrate into the inside of the rotating shaft seat 603, and under the elastic force of the tension spring 604, the tension roller 602 provides elastic support to the fabric passing through the top of the tension roller 602, thereby improving the tension of the fabric when it is laid out and avoiding loose wrinkles caused by low tension of the fabric. At the same time, the adjustment plate 605 can be pressed against the bottom of the tension spring 604 by rotating the adjustment screw 606, so that the tension can be adjusted according to the flexibility of the fabric.

[0029] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
