Description

Technical Field

[0001] This utility model relates to the field of embroidery machine technology, specifically to an embroidery machine head with a buffer structure. Background Technology

[0002] In the textile industry, embroidery machines are key equipment for creating exquisite patterns on fabrics, and their performance directly affects embroidery quality and production efficiency. Among these components, the embroidery machine head, as a core part, is responsible for driving the needles and presser feet, and the rationality of its structural design is crucial.

[0003] Existing embroidery machine heads (typically, as disclosed in application number CN202211571529.X, an independent embroidery machine head and embroidery machine) are prone to significant impact and vibration during operation due to the lack of an effective buffer structure, as the presser foot and needle tip undergo frequent up-and-down reciprocating movements. On one hand, this impact force leads to unstable pressure from the presser foot on the fabric, affecting the flatness and precision of the embroidery pattern, and may even damage the fabric. On the other hand, the impact force on the needle tip during high-speed movement reduces the precision of the fit between the needle tip and the needle, increasing the probability of thread breakage, needle breakage, and other malfunctions, thus reducing production efficiency and increasing equipment maintenance costs. Therefore, it is urgent to improve the structure of the embroidery machine head to solve the above-mentioned technical problems. Utility Model Content

The presser foot can move up and down along the length of the presser foot drive rod. The presser foot elastic element provides a buffering elastic force for the up and down movement of the presser foot on the presser foot drive rod. The needle sleeve is fixed to the needle drive rod. The shaft of the needle sleeve is in telescopic engagement with the sleeve hole on the needle sleeve. The needle elastic element provides a buffer elastic force for the shaft of the needle sleeve to move up and down along the sleeve hole.

[0006] Furthermore, it also includes a limiting structure that provides a limit for the up and down movement of the presser foot. The limiting structure includes a limiting screw, a limiting groove, and a screw hole. The presser foot drive rod is provided with the aforementioned screw hole. The limiting groove is provided on the side of the through hole and communicates with the through hole.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0024] This utility model provides an embroidery machine head with a buffer structure.

[0025] In this embodiment, refer to Figure 1-5 The embroidery machine head with a buffer structure includes a machine head housing 1, a presser foot drive rod 2, a presser foot 3, a needle drive rod 4, a needle tip drive rod 5, a cam 6, and a needle tip 7, and also includes a presser foot elastic element 8, a needle tip sleeve 9, and a needle tip elastic element 10. The presser foot is fitted onto the presser foot drive rod through the through hole 11 on the presser foot. The presser foot can move up and down along the length of the presser foot drive rod. The presser foot elastic element provides a buffer elastic force for the up and down movement of the presser foot on the presser foot drive rod. The needle sleeve is fixed on the needle drive rod. The shaft portion 12 of the needle sleeve is in telescopic cooperation with the sleeve hole 13 on the needle sleeve. The needle elastic element provides a buffer elastic force for the shaft portion of the needle sleeve to move up and down along the sleeve hole.

[0026] In the above technical solution, based on the traditional embroidery machine head structure, a presser foot elastic component, a needle tip sleeve, and a needle tip elastic component are added. The presser foot is fitted onto the presser foot drive rod through a through hole and can move up and down along the rod. The presser foot elastic component provides a buffering elastic force, which plays a buffering role when the presser foot moves. The needle tip sleeve is fixed to the needle tip drive rod, and the shaft of the needle tip is in telescopic cooperation with the sleeve hole of the needle tip sleeve. The needle tip elastic component provides a buffering elastic force for the up and down movement of the needle tip shaft along the sleeve hole, thereby reducing the impact force when the needle tip moves.

[0027] It effectively buffers the impact force generated during the movement of the presser foot and needle tip, making the pressure of the presser foot on the fabric more stable, improving the flatness and precision of the embroidery pattern; it ensures high-precision matching between the needle tip and the needle, reducing the probability of failures such as thread breakage and needle breakage, and improving production efficiency; it reduces equipment vibration and noise, reduces component wear, and extends the service life of the equipment.

[0028] Among them, the presser foot elastic element and the needle tip elastic element can be made of helical springs.

[0029] Specifically, it also includes a limiting structure that provides a limit for the up and down movement of the presser foot. The limiting structure includes a limiting screw 14, a limiting groove 15, and a screw hole 16. The presser foot drive rod is provided with the aforementioned screw hole 16. The limiting groove is provided on the side of the through hole and communicates with the through hole. The limiting screw extends from the limiting groove and is threadedly connected to the screw hole on the presser foot drive rod that extends into the through hole.

[0030] In this embodiment, the limiting structure consists of a limiting screw, a limiting groove, and a screw hole. The presser foot drive rod has a screw hole, and the side of the through hole on the presser foot has a limiting groove communicating with the through hole. The limiting screw extends into the limiting groove and is threadedly connected to the screw hole on the presser foot drive rod. By adjusting the position of the limiting screw, the vertical movement range of the presser foot on the presser foot drive rod is limited. This avoids problems such as misalignment and impact caused by excessive movement of the presser foot during operation, ensuring the accuracy and stability of the presser foot's movement and further improving embroidery precision. Simultaneously, it prevents the presser foot from accidentally detaching from the presser foot drive rod, enhancing the safety of equipment operation.

[0031] Specifically, the presser foot drive rod located above the presser foot is fixed with a spring sleeve 17 by screws. One end of the presser foot elastic element abuts against the spring sleeve, and the other end abuts against the presser foot.

[0032] In this embodiment, a spring sleeve is fixed to the presser foot drive rod above the presser foot by a screw. One end of the presser foot elastic element abuts against the spring sleeve, and the other end abuts against the presser foot. In this way, the spring sleeve provides a fixed support point for the presser foot elastic element. When the presser foot moves up and down, the presser foot elastic element can generate a buffering elastic force through compression and extension. By loosening the screw, the height of the spring sleeve can be adjusted, thereby adjusting the elastic pressure of the presser foot elastic element to adapt to different working conditions.

[0033] Specifically, the bottom of the pressure foot drive rod is screwed with an anti-loosening bolt 18.

[0034] In this embodiment, an anti-detachment bolt is screwed to the bottom of the presser foot drive rod. By tightening the anti-detachment bolt, a block is formed at the bottom of the presser foot drive rod to prevent the presser foot from accidentally detaching from the bottom of the presser foot drive rod.

[0035] Specifically, it also includes a sleeve 19, which is clamped and fixed to the needle drive rod by bolts, and the sleeve and the needle sleeve are fixedly connected by bolts.

[0036] In this embodiment, the clamp is fixed to the needle drive rod by bolts, and the clamp and the needle sleeve are also fixed together by bolts. This connection method achieves a stable connection between the needle sleeve and the needle drive rod, while facilitating the disassembly and installation of the needle sleeve.

[0037] Specifically, the shaft portion of the needle sleeve is provided with a collar 20 to prevent the shaft portion from disengaging from the sleeve hole.

[0038] In this embodiment, a collar is provided on the shaft of the nozzle sleeve. The size of the collar is larger than the diameter of the sleeve hole on the nozzle sleeve, thereby restricting the nozzle sleeve shaft from disengaging from the sleeve hole and ensuring a stable telescopic fit between the nozzle sleeve shaft and the nozzle sleeve sleeve hole.

[0039] Specifically, the cam is provided with a first positioning hole 21, and the machine head housing is provided with a second positioning hole 22 and a third positioning hole 23.

[0040] In this embodiment, a first positioning hole 21 is provided on the cam, and a second positioning hole and a third positioning hole are provided on the machine head housing. During assembly, the relative position of the cam and the machine head housing can be accurately determined by the cooperation of the positioning holes and the corresponding positioning rods. For example, when the first positioning hole is aligned with the second positioning hole, inserting the positioning rod will position the cam at the location where the assembly bolts face the opening of the housing, facilitating fixation during assembly. When the first positioning hole is aligned with the third positioning hole, inserting the positioning rod will position the cam in the stop position, ensuring that the machine head is in the stop position when leaving the factory.

[0041] Attention all technical personnel: Although this utility model has been described according to the specific embodiments above, the concept of this utility model is not limited to this utility model. Any modification that utilizes the concept of this utility model will be included within the scope of protection of this patent right.
