Technical Field

[0001] This utility model relates to the field of fabric spreading machine technology, and in particular to an automatic fabric spreading and cutting device. Background Technology

[0002] In the garment and textile industry, fabric spreading and cutting play a crucial role. Only regular cut pieces can be sewn into products that meet specifications. If the cut pieces are not regular, even the best sewing machine and the most skilled sewing worker will find it difficult to sew high-quality fabric products. Fabric spreading and cutting devices typically include a fabric feeding mechanism, a fabric cutting mechanism, and a fabric spreading mechanism. Fabric spreading mainly involves clamping the fabric ends and pulling them to the worktable for the fabric cutting device to cut.

[0003] Currently available fabric spreading and cutting devices in textile processing cannot move quickly and stably, and are unstable during cutting, which easily causes fabric wrinkles, resulting in low fabric spreading efficiency. Utility Model Content

[0004] The purpose of this invention is to provide an automatic fabric pulling and cutting device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

The tray, which is a rectangular frame structure, is slidably fitted onto the support. A driving device is installed at the bottom of the support and is connected to the tray for transmission. A fabric feeding groove is formed through the fabric spreading table. A fabric cutting device is installed at the top of the fabric spreading table. Several fixing blocks are fixedly connected at intervals to the bottom of the fabric feeding groove on the side of the fabric spreading table near the tray. A cylinder is fixedly installed on the fabric spreading table above the fixing blocks. The cylinder is drivenly connected to a connecting plate.

The drive motor 101 is fixed on one side of the bottom of the support 1 and is connected to the ball screw 102. The two guide rods are fixedly connected to the bottom of the support 1. A limit block 106 is installed on the side of the support 1 near the fabric spreading table 2. The limit block 106 is located on the side wall of the support 1 between the fabric spreading table 2 and the tray 3. The limit block is set to prevent the drive motor from malfunctioning and causing a collision.

[0027] like Figure 5 As shown, a transmission block 307 extends downward from the bottom of the support plate 3. A threaded hole is provided in the transmission block 307. The transmission block 307 is slidably connected to the ball screw 102 through the threaded hole. Two guide blocks 306 extend upward from the bottom of the support plate 3. Guide holes are provided in the guide blocks 306. The guide blocks 306 are slidably connected to the guide rod 105 through the guide holes. The support plate 3 is slidably connected to the bracket 1 through the ball screw 102 and the guide rod 105.

[0028] like Figure 3-4 As shown, a fabric feeding groove 201 is provided on the fabric feeding table 2, which runs through the fabric feeding table 2. Several fixed blocks 211 are fixedly connected at intervals at the bottom of the fabric feeding groove 201 on the side of the fabric feeding table 2 near the support plate 3. A cylinder 208 is fixedly installed on the fabric feeding table 2 above the fixed blocks 211. The cylinder 208 is driven by a connecting plate 209. Several upper pressing blocks 210 are fixedly provided at intervals at the bottom of the connecting plate 209. The upper pressing blocks 210 and the fixed blocks 211 are adjacent to each other to form a gap that communicates with the fabric feeding groove 201.

[0029] A fabric cutting device is installed on the top of the fabric spreading table 2. The fabric cutting device includes a drive motor 202, a ball screw 203, two support plates 204, two guide rods 205, a slider 206, and a cutting knife 207. The two support plates 204 are located on both sides of the top of the fabric spreading table 2. The ball screw 203 is rotatably connected between the two support plates. The two guide rods 205 are fixedly connected between the two support plates 204 at the bottom of the ball screw 203. The drive motor 202 is fixed to the top of the fabric spreading table 2. The top side of the fabric table 2 is connected to the ball screw 203. The slider 206 has a threaded hole and two guide holes in sequence. The slider 206 is slidably connected to the ball screw 203 and the guide rod 205 through the threaded hole and the guide hole. The fabric cutter 207 is fixed at the bottom of the slider 206.

[0030] like Figure 5-6 As shown, cylinders 301 are provided on both sides of the top of the pallet 3. Cylinders 301 are fixedly installed on the top of the pallet 3 via fixing plates 302. The two cylinders 301 are respectively connected to the two ends of the connecting plate 303. Two cylinders are provided because the pallet needs to clamp the fabric and drag it backward, so a higher clamping force is required. Several upper pressing blocks 304 are fixedly spaced at the bottom of the connecting plate 303. Fixing blocks 305 are fixedly connected to the bottom of the upper pressing blocks 304 on the pallet 3. The upper pressing blocks 304 and the fixing blocks 305 are adjacent to each other to form a gap that communicates with the fabric inlet groove 201.

[0031] like Figure 7-8 As shown, upper pressure block 1 210 and upper pressure block 2 304 are arranged alternately, and fixing block 1 211 and fixing block 2 305 are arranged alternately.

[0032] The working principle of this utility model:

[0033] The fabric to be cut is guided from the feed groove 201 on one side of the fabric pulling table 2 into the gap between the upper pressure block 210 and the fixing block 211. Then, the drive motor 101 is started to drive the ball screw 102 to rotate, thereby causing the tray 3 to slide towards the fabric pulling table 2 on the guide rod 105 and the ball screw 102. Figure 7-8As shown, the upper pressure block 210, the fixing block 211, the upper pressure block 304, and the fixing block 305 are interleaved, so that the fabric is simultaneously located in the gap between the upper pressure block 210, the fixing block 211, the upper pressure block 304, and the fixing block 305. Then, the two cylinders 301 are activated to drive the connecting plate 303 downward, causing the upper pressure block 304 to move towards the fixing block 305 to press the fabric. After the drive motor 101 reverses and drives the support plate 3 away from the fabric pulling table 2 to the preset position, the cylinder 208 is activated to drive the connecting plate 209 downward. The upper pressure block 210 moves toward the fixed block 211 to press the fabric. Then, the drive motor 202 is started to drive the ball screw 203 to rotate, so that the slider 206 moves on the ball screw 203 and the guide rod 205, which drives the cutting knife 207 at the bottom of the slider 206 to cut the fabric. After the cutting is completed, the drive motor 202 reverses to return to the initial position, and the cylinders 208 and 301 return to the initial position at the same time to loosen the fabric, so that the fabric falls onto the bracket 1. One operating cycle is completed. The above operation is repeated until the fabric pulling and cutting work is completed.

[0034] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention.
