Description

Technical Field

[0001] This utility model relates to the field of clothing sewing, and in particular to a material pushing structure for a double-sided wool hand sewing machine. Background Technology

[0002] In existing garment sewing technology, to achieve efficient and precise sewing, operators often need to manually push the garment towards the needle so that it can be sewn along a predetermined path. However, existing sewing equipment or auxiliary structures have certain design flaws. When the operator pushes the garment, some parts of the structure occupy the space where the fingers are placed, obstructing the operation. This obstruction not only restricts the operator's hand movements and makes operation extremely inconvenient, but also reduces the space between the hand and the garment, making it difficult for the operator to flexibly adjust the position and angle of the garment. This, in turn, affects the smoothness and quality of the sewing operation, reduces work efficiency, and increases the rework rate. Therefore, there is an urgent need for an improved technical solution that can effectively expand the space between the hand and the garment without affecting the sewing operation, thereby improving operational comfort and sewing results. Utility Model Content

[0003] This application provides a material pushing structure for a double-faced wool hand sewing machine, which solves a problem in the design of existing sewing equipment or auxiliary structures. In these designs, when the operator pushes the garment, parts of the structure occupy the space where fingers are placed, obstructing the operation. This obstruction not only restricts the operator's hand movements and makes operation extremely inconvenient during sewing, but also reduces the space for movement between the hand and the garment.

[0004] The technical solutions adopted in the embodiments of this application are as follows.

[0005] A material feeding structure for a double-sided wool hand sewing machine includes a table, a sewing machine head mounted on the table, an eccentric wheel mounted on the sewing section of the sewing machine head, a mounting base detachably connected to the sewing machine head, a swing arm hinged to the mounting base, a material feeding plate hinged to the mounting base, a presser foot block detachably connected to the table, and a reset component for repositioning the material feeding plate. The eccentric wheel rotates synchronously with the frequency of the needle's up-and-down movement. The middle of the swing arm is hinged to the mounting base. One end of the swing arm corresponds to the eccentric wheel, and the other end corresponds to the material feeding plate. The material feeding plate corresponds to the presser foot block. One end of the reset component is connected to the mounting base, and the other end corresponds to the material feeding plate. The eccentric wheel drives the swing arm to deflect at a certain angle at its hinge point, thereby pushing the material feeding plate into the presser foot block.

[0006] As a further improvement to the above technical solution: the pusher plate, the mounting base and the swing arm are all positioned by bolts, which facilitates maintenance and replacement of parts.

[0007] As a further improvement to the above technical solution: a bearing is provided at the end of the swing arm facing the eccentric wheel; the bearing corresponds to the eccentric wheel.

[0008] As a further improvement to the above technical solution: a movable plate is provided on the pusher plate; a first hook is provided on the movable plate; a second hook is provided on the mounting base; one end of the reset member corresponds to the first hook, and the other end of the reset member corresponds to the second hook; the reset member drives the pusher plate to rotate toward the swing arm.

[0009] As a further improvement to the above technical solution: a connecting plate is provided on the side of the swing arm facing the pusher plate; an adjusting component is threadedly connected to the connecting plate; the adjusting component is threadedly connected to the connecting plate; one end of the adjusting component abuts against the moving plate; the adjusting component can adjust the relative position of the pusher plate and the pressure foot block.

[0010] As a further improvement to the above technical solution: a limiting plate is provided at the bottom of the connecting plate to prevent the adjusting member from disengaging; the limiting plate and the connecting plate are L-shaped.

[0011] As a further improvement to the above technical solution: the presser foot block can be replaced according to different sewing processes.

[0012] As a further improvement to the above technical solution: the reset component is a tension spring.

[0013] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0014] 1. Due to the linkage mechanism of the eccentric wheel, swing arm and pusher plate, the pusher plate can accurately follow the movement rhythm of the needle, periodically push the fabric into the presser foot block and reset it in time, ensuring that the fabric is continuously and stably fed. This not only greatly improves sewing efficiency, but also effectively avoids sewing quality problems caused by poor fabric feeding, laying a solid foundation for high-quality sewing operations.

[0015] The bearing positioned at the end of the swing arm facing the eccentric wheel significantly reduces friction between them, effectively extending component lifespan, reducing energy consumption, and improving equipment operating efficiency and economy. Meanwhile, the pusher plate, mounting base, and swing arm are bolted together, and the convenient and quick disassembly design makes maintenance and parts replacement easy, greatly reducing equipment downtime and ensuring efficient production operation.

[0016] To meet diverse sewing needs, the swing arm is specially equipped with an adjustment mechanism. By rotating the adjustment mechanism to adjust its depth, the relative position of the pusher plate and presser foot can be precisely controlled. This ensures that the pushing force reaches its optimal state in various complex sewing processes, significantly improving sewing accuracy and quality. Furthermore, the L-shaped limiting plate at the bottom of the connecting plate effectively prevents the adjustment mechanism from disengaging during operation, further enhancing the stability and reliability of the pushing structure and ensuring safe operation of the equipment.

[0017] The replaceable presser foot is another highlight of this structure, allowing for flexible adjustment based on different sewing processes such as fabric thickness and stitching method. This significantly improves the versatility and adaptability of the pusher structure, broadening the application range of the equipment. The inclusion of a reset spring provides the pusher with an automatic reset function. When the thrust of the eccentric wheel on the swing arm weakens, the spring promptly applies force to reset the pusher, ensuring a smooth and consistent pusher process, reducing manual intervention, and increasing automation.

[0021] This application provides a material pushing structure for a double-faced wool hand sewing machine, which solves a problem in the design of existing sewing equipment or auxiliary structures. In these designs, when the operator pushes the garment, parts of the structure occupy the space where fingers are placed, obstructing the operation. This obstruction not only restricts the operator's hand movements and makes operation extremely inconvenient during sewing, but also reduces the space for movement between the hand and the garment.

[0022] The technical solution in this application embodiment is to solve the above problems, and the overall idea is as follows:

[0023] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0024] A double-sided wool hand sewing machine pusher structure includes a table 1, a sewing machine head 2 mounted on the table 1, an eccentric wheel 3 mounted on the sewing section of the sewing machine head 2, a mounting base 4 detachably connected to the sewing machine head 2, a swing arm 5 hinged to the mounting base 4, a pusher plate 6 hinged to the mounting base 4, a presser foot block 7 detachably connected to the table 1, and a reset member 8 for repositioning the pusher plate 6. The eccentric wheel 3 rotates synchronously with the frequency of the needle's up-and-down movement. The middle of the swing arm 5 is hinged to the mounting base 4. One end of the swing arm 5 corresponds to the eccentric wheel 3, and the other end corresponds to the pusher plate 6. The pusher plate 6 corresponds to the presser foot block 7. One end of the reset member 8 is connected to the mounting base 4, and the other end corresponds to the pusher plate 6. The eccentric wheel 3 drives the swing arm 5 to deflect at a certain angle at its hinge point, thereby pushing the pusher plate 6 into the presser foot block 7.

[0025] The pusher plate 6, mounting base 4 and swing arm 5 are all positioned by bolts, which facilitates maintenance and replacement of parts.

[0026] A bearing 51 is provided at one end of the swing arm 5 facing the eccentric wheel 3; the bearing 51 corresponds to the eccentric wheel 3.

[0027] A movable plate 61 is provided on the pusher plate 6; a first hook 62 is provided on the movable plate 61; a second hook 41 is provided on the mounting base 4; one end of the reset member 8 corresponds to the first hook 62, and the other end of the reset member 8 corresponds to the second hook 41; the reset member 8 drives the pusher plate 6 to rotate toward the swing arm 5.

[0028] A connecting plate 52 is provided on the side of the swing arm 5 facing the pusher plate 6; an adjusting component 53 is threadedly connected to the connecting plate 52; the adjusting component 53 is threadedly connected to the connecting plate 52; one end of the adjusting component 53 abuts against the moving plate 61; the adjusting component 53 can adjust the relative position of the pusher plate 6 and the pressure foot block 7.

[0029] The bottom of the connecting plate 52 is provided with a limiting plate 54 to prevent the adjusting member 53 from disengaging; the limiting plate 54 and the connecting plate 52 are L-shaped.

[0030] The presser foot 7 can be replaced according to different sewing processes.

[0031] The reset component 8 is a tension spring.

[0032] Workflow: The mounting base 4 is detachably connected to the sewing machine head 2 using bolts, ensuring the mounting base 4 corresponds to the eccentric wheel 3; the middle of the swing arm 5 is fixed to the mounting base 4 via a hinge shaft, with one end aligned with the eccentric wheel 3 and the other end aligned with the pusher plate 6; a bearing 51 is installed on the end of the swing arm 5 facing the eccentric wheel 3, ensuring the bearing 51 is tightly against the outer circumference of the eccentric wheel 3 to reduce friction; the pusher plate 6 is hinged to the mounting base 4, aligning it with the presser foot block 7; a movable plate 61 is installed on the pusher plate 6, and bolts are used to restrict the movement of the pusher plate 6, the mounting base 4, and the swing arm 5. The relative positions facilitate subsequent maintenance; one end of the spring of the reset piece 8 is hung on the first hook 62 of the moving plate 61 of the pusher piece 6, and the other end is hung on the second hook 41 of the mounting base 4, ensuring that the spring is in a naturally stretched state, which can drive the pusher piece 6 to reset towards the swing arm 5; an adjusting piece 53 is threadedly connected to the connecting plate 52 of the swing arm 5, and the adjusting piece 53 is rotated so that one end abuts against the moving plate 61. By adjusting the screw depth of the adjusting piece 53, the relative position of the pusher piece 6 and the presser foot block 7 is adjusted to ensure that the pushing force is moderate during sewing; an L-shaped limiting plate 54 is installed at the bottom of the connecting plate 52 to prevent the adjusting piece 53 from coming off during operation; according to the sewing process, such as fabric thickness and sewing method, the corresponding specification of the presser foot block 7 is selected and detachably connected to the table surface 1 by bolts to ensure that the presser foot block 7 and the pusher piece 6 are aligned.

[0033] Needle-driven eccentric wheel 3: When the sewing machine is started, the needle moves up and down reciprocally, driving the eccentric wheel 3 to rotate synchronously.

[0034] Swing of the swing arm 5: When the eccentric wheel 3 rotates, its profile pushes the bearing 51 at one end of the swing arm 5, causing the swing arm 5 to swing away from the eccentric wheel 3 with the hinge point as the center.

[0035] Pushing the material pusher 6 forward: The other end of the swing arm 5 pushes the material pusher 6, causing it to move into the presser foot block 7, pushing the fabric forward. The material pusher 6 cooperates with the presser foot block 7 to ensure that the fabric moves smoothly.

[0036] Reset component 8 pulls back pusher plate 6: When the eccentric wheel 3 rotates to a specific position and the pushing force on the swing arm 5 weakens, the tension spring of the reset component 8 drives the pusher plate 6 to rotate in the direction of the swing arm 5 through the tension, so that the pusher plate 6 is reset.

[0037] Circular feeding: As the needle moves up and down continuously, the eccentric wheel 3 drives the swing arm 5 to swing back and forth, and the pusher plate 6 periodically pushes the material into the presser foot block 7 and resets, so as to realize the continuous feeding of the fabric.
