Description

Technical Field

[0001] This utility model relates to the field of leather sewing machine technology, specifically to an industrial sewing machine for leather processing. Background Technology

[0002] Sewing machines can sew fabrics such as cotton, linen, silk, wool, and synthetic fibers, as well as products made of leather, plastic, and paper. The stitches produced are neat, beautiful, flat, and strong. Sewing is fast and easy to use. Sewing machines have also become one of the important instruments for leather processing. In order to ensure the efficiency of leather processing, an adjustable sewing machine for leather processing is needed.

[0003] Utility model patent CN215668444U discloses an adjustable leather processing sewing machine, including a table. A groove is formed on the upper surface of the table, and a sewing table is mounted on the upper side of the groove. A slider is installed on the lower surface of the sewing table near the groove, and a pulley is provided on the side of the slider. A first magnetic block is installed on the edge of the sewing table. A sewing machine is mounted on the upper surface of the sewing table, and a first handle is installed on the side of the sewing machine. A second handle is connected to the side of the sewing table away from the sewing machine. Support and adjustment leg mechanisms are installed at the four corners of the lower end of the table, and an operating position is provided on the side of the table. This utility model uses a slider that slides within the groove on the sewing table, which assists in the stable sliding of the entire device. It also effectively increases the flexibility of adjusting the sewing machine on the sewing table, thereby increasing the operating area of ​​the worktable when processing leather and ensuring a more spacious processing area.

[0004] However, the above-mentioned existing technical solutions still have the following shortcomings: When the device is adjusted, it is necessary to remove the two bolts on the front side and insert them into the corresponding holes. This results in a limited range of angle adjustment for the device, which can only be fixed in the preset position. Moreover, the operator needs to bear the overall weight of the table and the sewing machine during adjustment, which makes the adjustment physically demanding and difficult to meet the usage requirements. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide an industrial sewing machine for leather processing, so as to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an industrial sewing machine for leather processing, including a table, a sewing table is provided on the top of the table, a sewing machine is fixed on the top of the sewing table, an angle adjustment mechanism is provided below the table, a lifting mechanism and a driving mechanism are provided on the surface of the angle adjustment mechanism, a displacement mechanism is provided on the top of the table, and a controller is fixed on the top of the table;

[0007] The angle adjustment mechanism includes a base plate, two supports are fixed to the top of the base plate, guide rods slide through the top of the supports, a horizontal plate is fixed to the top of the two guide rods, L-shaped plates are fixed to the left and right sides of the horizontal plate, and semi-circular plates are fixed to the left and right sides of the bottom of the platform. An arc groove is opened on the surface of the semi-circular plate, and a shank bolt is slidably connected to the inner wall of the arc groove. The shank bolt is threaded through the L-shaped plate.

[0008] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0009] This invention achieves continuous angle adjustment of the sewing table by using a synergistic design of an arc groove and a bolt with a handle, replacing the bolt-hole fixing method and providing a wider adjustment range. The bolt with a handle and the arc groove form a support structure, allowing a single person to complete the table angle adjustment, solving the problems of traditional sewing machine angle adjustment requiring disassembly and reassembly, rigid positioning, and heavy physical load on manual support of the table.

[0017] The specific embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0018] Please see Figure 1-6 An industrial sewing machine for leather processing includes a table 1, a sewing table 2 on the top of the table 1, a sewing machine 3 fixed on the top of the sewing table 2, an angle adjustment mechanism 4 below the table 1, a lifting mechanism 6 and a drive mechanism 7 on the surface of the angle adjustment mechanism 4, a displacement mechanism 5 on the top of the table 1, and a controller 8 fixed on the top of the table 1.

[0019] The angle adjustment mechanism 4 includes a base plate 401. Two supports 402 are fixed to the top of the base plate 401. Guide rods 403 slide through the top of the supports 402. A horizontal plate 404 is fixed to the top of the two guide rods 403. L-shaped plates 405 are fixed to the left and right sides of the horizontal plate 404. Semicircular plates 406 are fixed to the left and right sides of the bottom of the platform 1. An arc groove 407 is opened on the surface of the semicircular plate 406. A shank bolt 408 is slidably connected to the inner wall of the arc groove 407. The shank bolt 408 is threaded through the L-shaped plate 405.

[0020] Through the above technical solution, the angle adjustment mechanism 4 is fixed in the base position by the base plate 401, the bracket 402 supports the guide rod 403 to achieve vertical guidance, and the horizontal plate 404 and the L-shaped plate 405 form a linkage frame; the semi-circular plate 406 is fixed to the bottom of the table plate 1, and its arc groove 407 and the shank bolt 408 constitute the core adjustment unit. During operation, the shank bolt 408 is loosened to release the locking of the L-shaped plate 405, and the table plate 1 is manually pushed to rotate around the axis of the shank bolt 408 through the arc groove 407. After the angle is adjusted to the target position, the shank bolt 408 is tightened again to pass through the L-shaped plate 405 to complete the rigid fixation. The arc groove 407 design breaks through the traditional plug-in type limit, realizing stepless adjustment of the angle of the table plate 1, adapting to any leather sewing tilt angle requirements. The shank bolt 408 replaces the bolt disassembly and reassembly process, making the operation more efficient; the L-shaped plate 405 and the shank bolt 408 form a support structure, so that the operator only needs to apply a small pushing force to overcome the weight of the sewing machine 3, solving the problem of laborious adjustment of traditional devices.

[0021] The displacement mechanism 5 includes two side plates 501, which are fixed to the top of the platform 1. A motor 502 is fixed to the surface of the side plate 501. The output shaft of the motor 502 passes through the side plate 501 and is fixed to a lead screw 503. The lead screw 503 is rotatably installed between the two side plates 501. A movable platform 504 is threadedly connected to the surface of the lead screw 503. The surface of the movable platform 504 is fixedly connected to the surface of the sewing table 2.

[0022] Through the above technical solution, the displacement mechanism 5 fixes the position of the motor 502 and the lead screw 503 through the side plate 501. The motor 502 receives the command from the controller 8 to drive the lead screw 503 to rotate. The threaded sleeve embedded in the movable table 504 meshes with the lead screw 503 to generate axial displacement, which drives the sewing table 2 to move linearly along the surface of the table plate 1. The electric translation of the sewing table 2 is achieved by the motor 502. The operator can control the position with one button through the controller 8, avoiding the physical consumption of manual pushing.

[0023] The surface of the table 1 has a groove, and a linear guide rail 505 is fixed to the inner wall of the groove. Two sliders 506 are slidably connected to the top of the linear guide rail 505, and the top of the sliders 506 is fixedly connected to the bottom of the sewing table 2.

[0024] With the above technical solution, when the lead screw 503 pushes the movable table 504, the slider 506 rolls along the linear guide rail 505, forcibly constraining the movement trajectory of the sewing table 2 to be an absolute straight line.

[0025] The lifting mechanism 6 includes a driven shaft 601, both ends of which are rotatably connected to the surface of the bracket 402. Two gears 602 are fixed on the surface of the driven shaft 601. The angle adjustment mechanism 4 has teeth 603 on its surface, and the gears 602 mesh with the teeth 603.

[0026] Through the above technical solution, the lifting mechanism 6 is connected to the bracket 402 by bearings at both ends of the driven shaft 601, and the gear 602 is installed on the surface of the driven shaft 601; the side of the horizontal plate 404 of the angle adjustment mechanism 4 is machined with teeth 603. When the drive mechanism 7 drives the driven shaft 601 to rotate, the gear 602 and the teeth 603 mesh and drive, forcing the horizontal plate 404 to rise and fall axially along the guide rod 403, and simultaneously changing the height of the platform 1 from the ground, supporting stepless height adaptation to different workers.

[0027] The drive mechanism 7 includes a connecting plate 701, which is fixed between two side supports 402. A seated bearing 702 is fixed to the top of the connecting plate 701. A worm gear 703 is fixedly connected to the inner wall of the seated bearing 702. A handwheel 704 is fixed to one end of the worm gear 703. A worm wheel 705 meshes with the surface of the worm gear 703. The worm wheel 705 is fixed to the surface of the driven shaft 601.

[0028] Through the above technical solution, the drive mechanism 7 is integrated into the bracket 402 through the connecting plate 701, the worm 703 is fixed by the bearing 702, the handwheel 704 is rotated to drive the worm 703 to rotate, the worm 703 and the worm wheel 705 form a 90° interlaced shaft transmission, the worm wheel 705 is press-fitted to the driven shaft 601 to drive it to rotate, and finally the torque of the handwheel 704 is amplified and transmitted to the lifting mechanism 6.

[0029] A accordion cover 507 is fixed to the surface of the side panel 501, and one end of the accordion cover 507 is fixedly connected to the surface of the movable table 504.

[0030] Through the above technical solution, one end of the bellows cover 507 is riveted to the side plate 501, and the other end is glued to the side of the movable platform 504. It expands and contracts with the displacement of the movable platform 504, completely covering the lead screw 503 and preventing the leather from contacting the lead screw 503.

[0031] Both the tabletop 1 and the semi-circular plate 406 are made of aluminum alloy.

[0032] Through the above technical solutions, aluminum alloy has a density that is only 1 / 3 that of steel, making it lighter overall and improving portability.

[0033] Working principle: When adjusting the angle, loosen the bolts 408 on both sides and gently push the table 1 so that the arc groove 407 of the semicircular plate 406 slides on the surface of the bolts 408. After the angle is in place, tighten the bolts 408 to complete the sewing tilt angle setting. When adjusting the height, turn the handwheel 704 to drive the worm gear 703 to rotate. The worm wheel 705 drives the driven shaft 601 to rotate. The gear 602 rolls along the teeth 603 on the side of the horizontal plate 404, forcing the horizontal plate 404 to rise and fall along the guide rod 403, realizing stepless adjustment of the working height. When the sewing table 2 is displaced, the motor 502 drives the lead screw 503 to rotate. The movable table 504 converts the rotational motion into linear motion. At the same time, the slider 506 on the linear guide rail 505 supports the sewing table 2 to move smoothly. The bellows cover 507 extends and retracts synchronously for protection. Through the above design, the problems of traditional sewing machine 3 requiring disassembly and reassembly for angle adjustment, rigid positioning, and heavy physical load for manual support of the table 1 are solved.
