Description

Technical Field

[0001] This utility model relates to the field of double-needle machine technology, and in particular to a double-needle machine for garment processing. Background Technology

[0002] Double-needle sewing machines in garment processing are primarily used to improve the efficiency and quality of garment sewing, meeting the demand for double-thread stitching in garment production. They can simultaneously create two parallel seams in a single operation, suitable for sewing various garments, such as shirt cuffs, trouser hems, and collars, resulting in more aesthetically pleasing and durable stitches and enhancing the overall quality of the garment. Through the application of double-needle machines, garment manufacturers can improve production efficiency, reduce production costs, and meet market demand for high-quality clothing. In practical applications, double-needle sewing machines in garment processing typically require the following technologies:

[0003] A high-precision needle position adjustment system ensures the accuracy of the double needle spacing and sewing stitch.

[0004] A stable thread tension control system ensures that the tension of the two seams is consistent, avoiding uneven tension.

[0005] The efficient fabric feeding mechanism can push the fabric evenly, preventing fabric shifting or wrinkling.

[0006] The intelligent sewing speed adjustment function adapts to fabrics of different materials and thicknesses.

[0007] A durable and low-noise drive system ensures stable operation of the equipment over long periods of time.

[0008] Currently, various equipment and methods are used to realize the functions of double-needle sewing machines in garment processing. Some manufacturers use traditional mechanical transmission double-needle machines, which achieve double-needle sewing through complex mechanical structures, but their operation is relatively cumbersome and difficult to debug. Other manufacturers use computer-controlled double-needle machines, which have advantages such as high automation and flexible programming, but the cost is higher. Some manufacturers have also launched double-needle machines with special functions, such as models that can perform zigzag stitches or decorative stitches, to meet the needs of different garment styles.

[0009] For example, a Chinese patent discloses a double-needle sewing device for garment processing, patent number: CN219752650U. After using the double-needle sewing machine body, the fixed slot and the fixed block can be engaged and fixed together, thereby fixing the protective half-groove and the connecting groove, and fixing the two protective half-grooves together. This isolates and protects the sewing needle when it is not in use, preventing it from getting wet and damaged, and preventing the sewing needle from causing injury to people when it is not in use. When the sewing needle needs to be used again, the fixed block can be separated from the fixed slot, and the protective half-groove can be separated from the connecting groove.

[0010] However, the above method has a prominent problem: although the device can isolate and protect the sewing needle, since the sewing needle is started by a pedal, the device lacks a limit function for the pedal. If the operator steps on the pedal unexpectedly, it can easily cause impact and excessive wear to the transmission parts, needles, etc. of the machine and protective structure, thus shortening the service life of the equipment. Utility Model Content

[0011] To address the shortcomings of existing technologies, this utility model provides a double-needle garment processing machine. It solves the technical problem that while the device can isolate and protect the sewing needle, since the sewing needle is controlled by a pedal, the aforementioned device lacks a pedal-limiting function. If the operator steps on the pedal unexpectedly, it can easily cause impact and excessive wear to the transmission components, needles, etc. of the machine and protective structure, thus shortening the service life of the equipment.

[0012] To achieve the above objectives, this utility model provides the following technical solution:

[0013] A double-needle garment processing machine includes a garment processing table. A sliding and limiting bonding mechanism is slidably connected inside the garment processing table. The bonding mechanism includes a wedge-shaped slider, a U-shaped limiting seat, and a support column. The wedge-shaped slider is slidably connected inside the garment processing table. The U-shaped limiting seat is fixedly connected to the outer surface of the wedge-shaped slider. The support column is fixedly connected to the lower end of the U-shaped limiting seat. A mounting mechanism for supporting the bonding mechanism is fixedly connected to one side of the garment processing table. The mounting mechanism includes a mounting base, which is fixedly connected to one side of the garment processing table. A pushing mechanism for sliding the bonding mechanism is provided inside the mounting base. The pushing mechanism includes a lifting slider and a wedge-shaped groove. The lifting slider is slidably connected inside the mounting base, and the wedge-shaped groove is formed inside the lifting slider, with the wedge-shaped groove and the outer surface of the wedge-shaped slider being in contact.

[0014] Preferably, the garment processing table is rotatably connected to a pedal body, and the U-shaped limiting seat and the outer surface of the pedal body are in contact.

[0015] Preferably, a first spring is sleeved on the outer surface of the support column away from the lifting slider, and the first spring is sleeved inside the garment processing table.

[0016] Preferably, a dovetail-shaped slider is fixedly connected to the lower end of the support column, the dovetail-shaped slider is slidably connected inside the garment processing table, and a second spring is sleeved on the lower end of the lifting slider.

[0017] Preferably, the second spring is sleeved inside the mounting base, and a round rod is fixedly connected to the outer surface of the lifting slider, the round rod being slidably connected inside the mounting base.

[0018] Preferably, the lifting slider is internally connected to a pull rod, and the pull rod is internally connected to a limit block.

[0019] Preferably, the limiting block is engaged with the outer surface of the round rod, and the outer surfaces of the lifting slider and the pull rod are fitted with tension springs.

[0020] Preferably, the upper end of the garment processing table is fixedly connected to the machine body, and two needles are provided inside the machine body.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. Step on the lifting slider to make it slide downwards within the mounting base. As the lifting slider slides, its internal wedge-shaped groove pushes the wedge-shaped slider towards one end of the pedal body through the inclined surface. The wedge-shaped slider drives the U-shaped limit seat and support column to move. The U-shaped limit seat fits against the surface of the pedal body to limit its movement and prevent accidental activation. The support column provides support for the pedal and prevents damage caused by workers stepping on the pedal forcefully. By limiting the pedal, accidental activation of the pedal when it is not needed is prevented, reducing the risk of accidents caused by misoperation and ensuring the safety of the operator.

[0023] 2. When the position of the lifting slider needs to be fixed, pull the lever to rotate the limit block. The round rod will press against the surface of the limit block to make it rotate. When the lever rotates, the lifting slider is limited by the inner surface of the limit block against the round rod, ensuring its stability when placed. When it is necessary to remove the limit of the lifting slider, manually pull the limit block to rotate, and then pull the lever to remove the limit. Manually pulling the lever and the limit block can realize the fixing and release of the limit. The operation is simple and convenient, improving work efficiency. Attached Figure Description

[0030] This application provides a double-needle garment processing machine that effectively solves the problem that while the device can isolate and protect the sewing needle, the lack of a pedal-controlled limit function means that if the operator steps on the pedal unexpectedly, it can easily cause impact and excessive wear to the transmission components and needles of the machine and protective structure, shortening the equipment's lifespan. By pressing down on the lifting slider, it slides downwards within the mounting base. As the lifting slider slides, its internal wedge-shaped groove pushes the wedge-shaped slider towards the end closest to the pedal body through an inclined surface. The wedge-shaped slider drives the U-shaped limit seat and support column to move. The U-shaped limit seat conforms to the surface of the pedal body to limit its movement, preventing accidental activation. The support column provides support for the pedal, preventing damage caused by the operator stepping on the pedal forcefully. By limiting the pedal, accidental activation when not needed is prevented, reducing the risk of accidents due to misoperation and ensuring the safety of the operator.

[0031] Example

[0032] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the technical solution in this application embodiment effectively solves the technical problem that while the device can isolate and protect the sewing needle, since the sewing needle is controlled by a pedal, the device lacks a pedal limiting function. If the operator steps on the pedal unexpectedly, it can easily cause impact and excessive wear to the transmission components and needles of the machine and protective structure, shortening the equipment's service life. The overall concept is as follows: A double-needle garment processing machine includes a garment processing table 11. A sliding limiting fitting mechanism is slidably connected inside the garment processing table 11. The fitting mechanism includes a wedge-shaped slider 12, a U-shaped limiting seat 13, and a support... The support column 14 and wedge-shaped slider 12 are slidably connected inside the garment processing table 11. A U-shaped limiting seat 13 is fixedly connected to the outer surface of the wedge-shaped slider 12. The support column 14 is fixedly connected to the lower end of the U-shaped limiting seat 13. The sliding U-shaped limiting seat 13 adheres to the surface of the pedal, limiting its movement and preventing accidental activation. The U-shaped limiting seat 13 drives the support column 14 to slide, providing support for the pedal and preventing damage caused by workers stepping on it forcefully. A mounting mechanism for the support and fitting mechanism is fixedly connected to one side of the garment processing table 11. The mounting mechanism includes a mounting base 15, which is fixedly connected to the garment processing table 11. On one side of the garment processing table 11, a mounting base 15 is fixed to provide mounting support. The mounting base 15 contains a pushing mechanism for the sliding of the compression and bonding mechanism. This pushing mechanism includes a lifting slider 16 and a wedge-shaped groove 17. The lifting slider 16 is slidably connected inside the mounting base 15, and the wedge-shaped groove 17 is formed inside the lifting slider 16. The outer surfaces of the wedge-shaped groove 17 and the wedge-shaped slider 12 are in contact. When the lifting slider 16 is pressed down, it slides. As the lifting slider 16 slides, the inclined surface of the wedge-shaped groove 17 pushes the wedge-shaped slider 12 towards one end of the U-shaped limiting seat 13 for limiting. The pedal body 18 is internally rotatably connected to the U-shaped limiting seat 13, which is in contact with the outer surface of the pedal body 18. When the pedal is stepped on for garment processing, the lifting slider 16 is stepped on and slides downward within the mounting base 15. When the lifting slider 16 slides, its internal wedge-shaped groove 17 pushes the wedge-shaped slider 12 towards one end of the pedal body 18 through the inclined surface. The wedge-shaped slider 12 drives the U-shaped limiting seat 13 and the support column 14 to move. The U-shaped limiting seat 13 fits against the surface of the pedal body 18 to limit its movement and prevent it from starting accidentally. The support column 14 provides support for the pedal and prevents the operator from stepping on the pedal too hard and causing damage.

[0033] A first spring 19 is sleeved on the outer surface of the support column 14 away from the lifting slider 16. The first spring 19 is sleeved inside the garment processing table 11. A dovetail slider 21 is fixedly connected to the lower end of the support column 14 and is slidably connected inside the garment processing table 11. A second spring 22 is sleeved on the lower end of the lifting slider 16 and is sleeved inside the mounting base 15. The first spring 19 and the second spring 22 provide reset force after the support column 14 and the lifting slider 16 lose their compressive force. The dovetail slider 21 provides a guiding function when the support column 14 slides. A round rod 23 is fixedly connected to the outer surface of the lifting slider 16 and is slidably connected inside the mounting base 15. A pull rod 24 is rotatably connected inside the lifting slider 16. A limit block 25 is rotatably connected inside the pull rod 24 and is locked onto the outer surface of the round rod 23. A tension spring 26 is sleeved on the outer surface of the lifting slider 16 and the pull rod 24. Holding the pull rod 24 moves the limit block 26. 5. During the rotation and locking operation, the round rod 23 presses against the surface of the limiting block 25, causing it to rotate. When the pull rod 24 rotates, the inner surface of the limiting block 25 adheres to the round rod 23, limiting the lifting slider 16 and ensuring its stability during placement. To release the limiting of the lifting slider 16, the limiting block 25 needs to be manually pulled to rotate. Pulling the pull rod 24 releases the limiting. When using the pedal for garment processing, first hold the surface of the pull rod 24 to rotate the limiting block 25. To remove the locking limit of the round rod 23, when it is necessary to fix the position of the lifting slider 16, pull the lever 24 to rotate the limiting block 25. The round rod 23 will press against the surface of the limiting block 25 to rotate. When the lever 24 rotates, the lifting slider 16 will be limited by the inner surface of the limiting block 25 against the round rod 23 to ensure its stability when placed. When it is necessary to remove the limit of the lifting slider 16, manually pull the limiting block 25 to rotate, and then pull the lever 24 to remove the limit.

[0034] The upper part of the garment processing table 11 is fixedly connected to the body 27. The body 27 is equipped with two needles 28. The garment to be processed is placed on the upper part of the garment processing table 11, and the body 27 performs sewing processing on the surface of the garment. The two needles 28 inside the body 27 work simultaneously, forming two parallel seams at one time. Compared with single-needle sewing, the sewing speed is greatly improved. After processing, the garment is removed for subsequent processing.

[0035] To address the problems existing in the prior art, this utility model provides a double-needle garment processing machine. When the lifting slider 16 is stepped on, it slides downward within the mounting base 15. As the lifting slider 16 slides, its internal wedge-shaped through groove 17 pushes the wedge-shaped slider 12 towards one end of the pedal body 18 through the inclined surface. The wedge-shaped slider 12 drives the U-shaped limiting seat 13 and the support column 14 to move. The U-shaped limiting seat 13 fits against the surface of the pedal body 18 to limit its movement and prevent accidental activation. The support column 14 provides support for the pedal and prevents damage caused by the operator stepping on the pedal forcefully. By limiting the pedal, accidental activation of the pedal when it is not needed is prevented, reducing the risk of accidents caused by misoperation and ensuring the safety of the operator.

[0036] Garment processing table 11: As the basic platform of the entire garment processing double needle machine, it provides space for the installation and operation of other components and supports the garment processing process;

[0037] Wedge slider 12: When the lifting slider 16 slides, it slides by being pushed by the wedge through groove 17, thereby driving the U-shaped limit seat 13 and the support column 14 to move, so as to limit and support the pedal body 18.

[0038] U-shaped limiting seat 13: fits against the surface of the pedal body 18 to limit the pedal and prevent it from starting unexpectedly;

[0039] Support column 14: Provides support for the pedal to prevent damage caused by workers stepping on the pedal forcefully, and works in conjunction with U-shaped limit seat 13;

[0040] Mounting base 15: Fixed to one side of the garment processing table 11, providing mounting support and guidance for components such as the lifting slider 16;

[0041] Lifting slider 16: It slides by stepping down or pulling up. Its internal wedge-shaped groove 17 pushes the wedge-shaped slider 12 to move, thereby controlling the pedal. Its outer round rod 23 is used to cooperate with the limit block 25 for limiting.

[0042] Wedge-shaped through groove 17: It is formed inside the lifting slider 16 and cooperates with the wedge-shaped slider 12 through the inclined surface to convert the sliding of the lifting slider 16 into the horizontal movement of the wedge-shaped slider 12;

[0043] Pedal body 18: for operators to step on to control the start and stop of garment processing;

[0044] First spring 19: Sleeves on the outer surface of support column 14, and provides reset power after support column 14 and lifting slider 16 lose the squeezing force, so that the component returns to the initial position;

[0045] Dovetail-shaped slider 21: Fixed to the lower end of the support column 14, it provides a guiding function when the support column 14 slides, ensuring smooth and accurate sliding;

[0046] The second spring 22 is sleeved on the lower end of the lifting slider 16 to provide the reset power for the lifting slider 16.

[0047] Round rod 23: Fixed to the outer surface of the lifting slider 16, and cooperates with the limiting block 25 to limit the lifting slider 16;

[0048] Pull rod 24: Internally connected to limit block 25, the limit block 25 is controlled by pulling and rotating operation to limit and release the lifting slider 16;

[0049] Limiting block 25: It is engaged with the outer surface of the round rod 23 to limit the lifting slider 16 and ensure its stability when placed.

[0050] Tension spring 26: It is sleeved on the outer surface of the lifting slider 16 and the pull rod 24 to assist the pull rod 24 and the limit block 25 in resetting;

[0051] Machine body 27: Fixed to the upper end of the garment processing table 11, with two needles 28 inside for garment sewing processing;

[0052] Needle 28: Two needles 28 work simultaneously to form two parallel seams at once, increasing sewing speed.

[0053] Working principle:

[0054] The first step is to place the garment to be processed on the upper part of the garment processing table 11. The machine body 27 performs sewing processing on the surface of the garment. The two needles 28 inside the machine body 27 work simultaneously to increase the sewing speed. After processing, the garment is removed for subsequent processing.

[0055] The second step involves using the pedal for garment processing. First, hold the pull rod 24 to rotate the limiting block 25, thus releasing the locking and limiting action of the round rod 23. When a limiting operation is required, step on the lifting slider 16 to make it slide downwards within the mounting base 15. As the lifting slider 16 slides, its internal wedge-shaped groove 17 pushes the wedge-shaped slider 12 towards one end of the pedal body 18 via its inclined surface. The wedge-shaped slider 12 drives the U-shaped limiting seat 13 and the support column 14 to move. The U-shaped limiting seat 13 then conforms to the surface of the pedal body 18 to limit its movement. To prevent accidental activation, the support column 14 provides support for the pedal, preventing damage caused by workers stepping on the pedal forcefully. When it is necessary to fix the position of the lifting slider 16, pull the lever 24 to rotate the limit block 25. The round rod 23 presses against the surface of the limit block 25 to make it rotate. When the lever 24 rotates, the lifting slider 16 is limited by the round rod 23 adhering to the inner surface of the limit block 25, ensuring its stability when placed. When it is necessary to cancel the limit of the lifting slider 16, manually pull the limit block 25 to rotate, and then pull the lever 24 to cancel the limit.

[0056] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
