Description

Technical Field

[0001] This utility model belongs to the field of trouser production technology, specifically relating to a positioning mechanism for a fabric cutting machine used in trouser production. Background Technology

[0002] A fabric cutting machine is a device used for cutting fabric. It is widely used in many textile-related industries such as garment manufacturing, home textile production, and bag making. In garment production, it can cut fabric into the required sizes for various parts of the garment, greatly improving production efficiency. In trouser production, the fabric cutting machine is needed to further cut the initially cut fabric into trouser pieces. Because many pieces of fabric are stacked together and cut simultaneously during the cutting process, and to avoid injury to the operator from the blades, it is not convenient to press and position the fabric around the blades during the cutting and moving process. Therefore, when cutting fabric manually with a fabric cutting machine, the uneven force on the fabric and the inability to press and position the fabric at the cut point can easily lead to large deviations in the shape and size of the cut multi-layered fabric, affecting subsequent production. Utility Model Content

[0003] This utility model provides a positioning mechanism for a fabric cutting machine used in trouser production. It features that the positioning pressure plate can press and position the fabric on both sides of the fabric cutting machine body by the contraction of several springs, and that the positioning pressure plate can move on the fabric as the fabric cutting machine body moves by the rolling of several balls.

[0004] This utility model provides the following technical solution: it includes a fabric cutting machine body, with fixed rods on both sides of the fabric cutting machine body, a fixed block at the end of the fixed rod away from the fabric cutting machine body, a plurality of movable rods slidably connected to the inner side of the fixed block, a positioning pressure plate at the bottom of the plurality of movable rods, a plurality of movable blocks at the bottom of the positioning pressure plate, a ball bearing at the bottom of the movable block, a connecting plate at the top of the plurality of movable rods, a plurality of springs between the fixed block and the connecting plate, a connecting rod at the top of the connecting plate, and a handle connecting two of the connecting rods.

[0005] The fixed block has several through slots inside, and the movable rod is slidably connected to the inside of the through slots.

[0006] The bottom of the positioning plate has several slots, and the movable block is slidably connected to the inside of the slots.

[0007] The cavity is equipped with a second spring, one end of which is fixedly connected to the movable block.

[0008] The movable block has a connecting groove at its bottom, and the ball bearing is located inside the connecting groove.

[0009] The two ends of the spring are fixedly connected to the fixed block and the connecting plate, respectively, and several springs are located on the outside of several movable rods.

[0010] The movable rod, the positioning pressure plate, and the connecting rod are all located on both sides of the fabric cutting machine body, and the handle is located on the top of the fabric cutting machine body.

[0011] The beneficial effects of this utility model are: the contraction of several springs can enable the positioning pressure plate to press and position the fabric on both sides of the fabric cutting machine body, avoiding the situation where the upper fabric is curled up due to less pressure during the cutting process, resulting in large deviations in the size and shape of the cut trouser pieces. Furthermore, the rolling of several balls allows the positioning pressure plate to move on the fabric as the fabric cutting machine body moves, ensuring the flatness of the fabric without affecting the movement of the fabric cutting machine body.

[0012] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0018] Please see Figures 1-4The present invention provides the following technical solution: it includes a fabric cutting machine body 1, with fixed rods 11 on both sides of the fabric cutting machine body 1, a fixed block 2 at the end of the fixed rod 11 away from the fabric cutting machine body 1, a plurality of movable rods 3 slidably connected to the inner side of the fixed block 2, a positioning pressure plate 4 at the bottom of the plurality of movable rods 3, a plurality of movable blocks 43 at the bottom of the positioning pressure plate 4, a ball bearing 44 at the bottom of the movable block 43, a connecting plate 31 at the top of the plurality of movable rods 3, a plurality of springs 22 between the fixed block 2 and the connecting plate 31, a connecting rod 32 at the top of the connecting plate 31, and two connecting rods 32 connected by a handle 321.

[0019] This implementation plan includes a fabric cutting machine body 1, which can cut stacked fabrics according to a designed shape and size. Since the fabric cutting machine body 1 is manually operated, the cutting is more flexible. Fixed rods 11 are provided on both sides of the fabric cutting machine body 1, and the fixed rods 11 are fixedly connected to the fabric cutting machine body 1. The two fixed rods 11 are symmetrical and horizontal. A fixed block 2 is provided at the end of the fixed rod 11 away from the fabric cutting machine body 1, and the fixed block 2 is fixedly connected to the fixed rod 11. Several movable rods 3 are slidably connected to the inner side of the fixed block 2. The movable rods 3 are perpendicular to the fixed block 2, and the distance between the movable rods 3 is the same. A positioning pressure plate 4 is provided at the bottom of the movable rods 3. Plate 4 is fixedly connected to the bottom of several movable rods 3, and the movable rods 3 are perpendicular to the positioning pressure plate 4. The height of the positioning pressure plate 4 can be adjusted by sliding the movable rods 3 up and down. The bottom of the positioning pressure plate 4 is provided with several movable blocks 43, which are evenly distributed on the bottom of the positioning pressure plate 4. The bottom of the movable blocks 43 is provided with ball bearings 44. When the positioning pressure plate 4 presses on the fabric, the ball bearings 44 at the bottom of the movable blocks 43 will contact the fabric, pressing the fabric on both sides of the fabric cutting machine body 1, so that it remains flat during the cutting process, avoiding the upper layer of fabric from curling up and causing deviations in the shape and size between the fabrics. At the same time, the rolling of the ball bearings 44 allows the positioning pressure plate 4 to move with the fabric cutting machine body 1 on the fabric. The top of the positioning plate 4 moves, so that the positioning pressure plate 4 always presses the fabric on both sides of the fabric cutting machine body 1 without interfering with the movement of the fabric cutting machine body 1. Several movable rods 3 have connecting plates 31 at their tops, which are fixedly connected to the movable rods 3. The connecting plates 31 are located on top of the fixed block 2. When the movable rods 3 move up and down, the distance between the connecting plates 31 and the fixed block 2 increases or decreases accordingly. Several springs 22 are provided between the fixed block 2 and the connecting plates 31. When the connecting plates 31 and the movable rods 3 move upward, the springs 22 are stretched. When the springs 22 contract, they drive the connecting plates 31 and the movable rods 3 downward. When the fabric is at the bottom of the positioning pressure plate 4, the tension of the contracting springs 22 will cause the fixed block 2 to move downward. The positioning plate 4 presses down on the top of the fabric. The top of the connecting plate 31 is provided with a connecting rod 32, which is fixedly connected to the connecting plate 31. The two connecting rods 32 are connected by a handle 321. The two ends of the handle 321 are fixedly connected to the two connecting rods 32 respectively. The handle 321 is in a horizontal state. The compression of several springs 22 can make the positioning plate 4 press and position the fabric on both sides of the fabric cutting machine body 1, so as to avoid the situation that the fabric on the top is curled up due to the small pressure during the cutting process, resulting in a large deviation in the size and shape of the cut trouser pieces. Furthermore, the rolling of several balls 44 allows the positioning plate 4 to move on the fabric as the fabric cutting machine body 1 moves, ensuring the flatness of the fabric without affecting the movement of the fabric cutting machine body 1.

[0020] The fixed block 2 has several through slots 21 inside, and the movable rod 3 is slidably connected to the inside of the through slots 21. The several through slots 21 are arranged at equal intervals. The connection between the movable rod 3 and the through slots 21 helps to ensure that the movable rod 3 is always in a vertical state.

[0021] The bottom of the positioning plate 4 has several slots 41, and the movable block 43 is slidably connected to the inside of the slots 41. By sliding the movable block 43 and the slots 41, the length of the movable block 43 outside the positioning plate 4 can be increased or decreased, which is beneficial for positioning the fabric when there are changes in the thickness of the fabric.

[0022] The cavity 41 is equipped with a second spring 42, one end of which is fixedly connected to the movable block 43. The second spring 42 ensures that the ball bearing 44 at the bottom of the movable block 43 is always in contact with the fabric, thus ensuring the positioning effect of the fabric.

[0023] The bottom of the movable block 43 is provided with a connecting groove 431, and the ball 44 is located inside the connecting groove 431. The size of the connecting groove 431 matches that of the ball 44, so that the ball 44 is limited while the rolling of the ball 44 is not affected.

[0024] The two ends of spring 22 are fixedly connected to the fixed block 2 and the connecting plate 31 respectively, and several springs 22 are located on the outside of several movable rods 3 respectively; when the connecting plate 31 moves upward, spring 22 will stretch accordingly, and the contraction of spring 22 can drive the connecting plate 31 and the movable rod 3 to move downward.

[0025] The movable rod 3, the positioning pressure plate 4, and the connecting rod 32 are all located on both sides of the fabric cutting machine body 1, and the handle 321 is located on the top of the fabric cutting machine body 1. The connecting rod 32, the movable rod 3, and the positioning pressure plate 4 can be lifted upward by the handle 321. When the fabric is below the positioning pressure plate 4, the movable rod 3 and the positioning pressure plate 4 will move downward by the spring 22 to position the fabric.

[0026] The working principle and usage process of this utility model are as follows: In use, the connecting rod 32, the movable rod 3, and the positioning pressure plate 4 are first lifted upward by the handle 321, so that the fabric cutting machine body 1 can move towards the position of the fabric. When the fabric is below the positioning pressure plate 4, the contraction of the spring 22 can drive the movable rod 3 and the positioning pressure plate 4 to move downward, and several balls 44 will press the fabric, thereby achieving the purpose of positioning the fabric. When the fabric cutting machine body 1 cuts and moves, the rolling of several balls 44 causes the positioning pressure plate 4 to move on the top of the fabric as the fabric cutting machine body 1 moves, so that the positioning pressure plate 4 always presses the fabric on both sides of the fabric cutting machine body 1.
