[0002] In the textile industry, fabric laying is a crucial step before cutting, directly affecting the accuracy and efficiency of subsequent cutting. Traditional fabric laying methods mainly rely on manual operation, which is not only labor-intensive but also inefficient, making it difficult to meet the demands of the modern textile industry for efficient and precise production. With the advancement of technology, automatic fabric laying machines have emerged and are gradually becoming the mainstream equipment in the textile industry.

[0003] An automatic fabric spreading machine is a computer-controlled mechanical device that can automatically perform operations such as fabric spreading, cutting, edge trimming, changing fabric rolls, and recording the number of layers spread. Automatic fabric spreading machines can complete complex fabric spreading operations without human intervention, greatly improving production efficiency. However, existing automatic fabric spreading machines still have some shortcomings. For example, when some automatic fabric spreading machines pull the fabric to move, wrinkles are prone to appear in the middle of the fabric near the pressure plate. Utility Model Content

Detailed Implementation

[0025] 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.

[0026] Example

[0027] Please see Figure 1-4In this embodiment of the present invention, an automatic fabric spreading machine includes a worktable 100, a fabric spreading mechanism 200, a fabric pressing mechanism 300, a leveling mechanism 400, and a cutting mechanism 500. A groove 110 is provided on the top surface of the worktable 100 near one end. A lead screw 130 is rotatably connected inside the groove 110. A motor 150 is fixedly connected to the outer wall of the worktable 100, and the motor shaft of the motor 150 is drively connected to the end of the lead screw 130. The fabric spreading mechanism 200 is located on the top surface of the worktable 100 and is used to mount rolled fabric, enabling the fabric to be spread on the top surface of the worktable 100. The fabric pressing mechanism 300 includes a pressure plate 310, which is located on the top surface of the worktable 100 near the groove 110 and can press down the end of the fabric during spreading. The leveling mechanism 400 includes two moving blocks 410. Both moving blocks 410 are provided with threaded holes. The two moving blocks 410 are screwed to the outer walls of both ends of the lead screw 130. The lead screw 130 is a positive and negative threaded lead screw. The two moving blocks 410 are symmetrical to each other. The top surface of each moving block 410 is fixedly connected to an electric telescopic rod 420. The output end of each electric telescopic rod 420 is fixedly connected to a rotating seat 430. The interior of each rotating seat 430 is rotatably connected to a fixed frame 440. The bottom of each fixed frame 440 is rotatably connected to a pressure roller 450. The top surface of each rotating seat 430 is fixedly connected to a motor 460. The motor shafts of each motor 460 are respectively connected to the ends of the fixed frames 440. The cutting mechanism 500 is fixedly connected to the fabric spreading mechanism 200. The cutting mechanism 500 includes a cutting blade 580, which can cut the flat fabric.

[0028] Specifically, the rolled fabric is installed on the fabric spreading mechanism 200. The fabric spreading mechanism 200 is controlled to move the fabric closer to the fabric pressing mechanism 300, and the end of the fabric is placed in the position of the fabric pressing mechanism 300. The pressure plate 310 is controlled to press down the end of the fabric. Then the fabric spreading mechanism 200 moves back, laying the fabric flat on the top surface of the worktable 100. The two fixed brackets 440 are initially collinear with the lead screw 130. When the fabric spreading mechanism 200 moves back, the two motors 460 are started, causing the two fixed brackets 440 to deflect in opposite directions until they are parallel and perpendicular to the lead screw 130 from a top view. Then the two electric telescopic rods 420 are controlled to retract. The two pressure rollers 450 are brought into contact with the fabric being laid. The motor 150 is started to drive the lead screw 130 to rotate, causing the two moving blocks 410 to move in opposite directions, thereby moving the two pressure rollers 450 away from each other and smoothing the fabric from the middle to both sides. After the fabric pulling mechanism 200 moves to the initial position, the cutting blade 580 is controlled to cut the fabric. The electric telescopic rod 420 extends to lift the pressure rollers 450, and the motors 150 and 460 are started to return the two pressure rollers 450 to the initial position. The fabric pulling mechanism 200 then drives the fabric to lay it flat for the next time. The fabric pressing mechanism 300 and the flattening mechanism 400 then repeat the above operation.

[0029] like Figure 1-2 As shown, in this embodiment, the top surface of the workbench 100 has two sliding grooves 120, and the interior of each sliding groove 120 is rotatably connected to a lead screw 140 driven by a motor. The fabric pulling mechanism 200 includes two side frames 210, the bottom of which is screwed to the outer wall of each lead screw 140. An installation roller 220 and several guide rollers 230 are arranged between the two side frames 210. The fabric pressing mechanism 300 includes two electric telescopic rods 330, the bottom ends of which are fixedly connected to the top surface of the workbench 100. The output ends of each electric telescopic rod 330 are fixedly connected to a connecting plate 320, and the ends of each connecting plate 320 are fixedly connected to the side wall of the pressing plate 310.

[0030] In this embodiment, the rolled fabric can be installed on the mounting roller 220, and then the end of the fabric is pulled through several guide rollers 230 to straighten the fabric so that it can remain roughly flat when laid flat. The motor 3 drives the lead screw 2 140 to rotate, which allows the fabric pulling mechanism 200 to move along the slide groove 2 120. When the fabric pulling mechanism 200 feeds the fabric, the electric telescopic rod 1 330 can extend to lift the pressure plate 310. When the fabric pulling mechanism 200 sends the end of the fabric to the bottom of the pressure plate 310, the electric telescopic rod 1 330 is controlled to retract, so that the bottom surface of the pressure plate 310 presses on the end of the laid fabric, preventing the fabric from moving with the fabric pulling mechanism 200 during the laying process.

[0031] like Figure 4 As shown, in this embodiment, the cutting mechanism 500 includes a strip frame 510. The outer wall of the strip frame 510 is fixedly connected to the side walls of two side frames 210. A support plate 520 is fixedly connected to the bottom surface of the strip frame 510. A clamping plate 530 is provided above the support plate 520. Two electric telescopic rods 540 are fixedly connected to the top surface of the clamping plate 530. The two electric telescopic rods 540 are installed and fixed to the strip frame 510. A sliding groove 511 is provided on the side wall of the strip frame 510 near the leveling mechanism 400. A lead screw 550 driven by a motor 4 is provided inside the sliding groove 511. A movable seat 560 is screwed onto the outer wall of the lead screw 550. An electric telescopic rod 570 is fixedly connected inside the movable seat 560. The bottom end of the electric telescopic rod 570 is fixedly connected to the cutting blade 580.

[0032] In practice, the end of the fabric passes through several guide rollers 230 and is placed in the gap between the support plate 520 and the clamping plate 530. The two electric telescopic rods 540 are extended to lower the clamping plate 530, narrowing the gap. The clamping plate 530 and the support plate 520 clamp the end of the fabric. After the end of the fabric is moved to the bottom of the pressure plate 310 and pressed down by the pressure plate 310, the electric telescopic rods 540 retract. The fabric pulling mechanism 200 moves back to the cutting position. Then, the electric telescopic rods 540 are extended to clamp the fabric between the clamping plate 530 and the support plate 520. At this time, the electric telescopic rods 570 are extended and the cutting blade 580 is started. Then, the motor 4 is started to drive the lead screw 550 to rotate, so that the cutting blade 580 moves laterally to cut the fabric.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
