Description

Technical Field

[0001] This utility model relates to the field of overlock machine technology, and in particular to an overlock machine for carpets with lifting presser feet. Background Technology

[0002] An overlock machine is a piece of equipment used to finish the edges of fabrics, securing the yarns with specific stitches to prevent fraying and creating a smooth, even edge for improved finish. It is a key piece of equipment in garment and textile production. In existing technology, some machines have a presser foot lifting function. This allows the overlock machine to work with fabrics of varying thicknesses. Typically, a lever is mounted on one side of the machine head; rotating the lever raises or lowers the presser foot.

[0003] However, in the existing technology, the drive device of the tie rod seat of the general overlock machine has a relatively complex structure and is difficult to assemble. It is difficult for non-professionals to install and maintain the drive device. In addition, the high precision requirements of the multi-component cooperation increase the probability of failure. During repair, multiple related components need to be disassembled to access the drive core, which prolongs the downtime, affects production efficiency, and cannot meet production needs. Utility Model Content

[0004] The purpose of this utility model is to provide a carpet overlock machine with a lifting foot, which aims to at least solve the technical problems of complex structure and inconvenient maintenance of the drive device of the pull rod seat in the existing overlock machine.

[0005] To achieve the above objectives, the present invention provides a carpet edge-locking machine with a raised foot, comprising:

[0006] The machine head, with a pull rod seat extending from one side of the machine head,

[0007] The first mounting post is disposed on one side of the machine head;

[0008] A connecting rod having a first mounting hole and a second mounting hole, the first mounting hole corresponding to the pull rod seat and the pull rod seat being rotatably connected to the connecting rod, and the second mounting hole corresponding to the first mounting post;

[0009] A drive assembly, which is mounted on the connecting rod;

[0010] A connecting rod, one end of which is drivenly connected to the drive assembly, and the other end of which is connected to the pull rod seat.

[0011] Furthermore, a bearing is fitted onto the pull rod seat, the inner ring of the bearing is connected to the pull rod seat, and the outer ring of the bearing is connected to the inner wall of the first mounting hole, so that the pull rod seat and the connecting rod are rotatably connected.

[0012] Furthermore, the first mounting post is arranged parallel to the tie rod seat.

[0013] Furthermore, the first mounting hole and the second mounting hole are located on the same plane.

[0014] Furthermore, the connecting rod is provided with a first opening so that the second mounting hole is provided in a U-shaped hole with one side open, and a first elastic claw and a second elastic claw are formed on both sides of the opening.

[0015] Furthermore, the first mounting post includes a rod and a mushroom head, the front end of the rod is connected to the machine head, the mushroom head is disposed at the end of the rod, and the first elastic claw and the second elastic claw are used to pass through the mushroom head and clamp the rod.

[0016] Furthermore, a U-shaped fastening ring is provided at the other end of the connecting rod. A first connecting plate and a second connecting plate are provided at opposite ends of the opening of the U-shaped fastening ring. A first threaded hole is provided on the first connecting plate, and a second threaded hole is provided on the second connecting plate. By inserting and tightening bolts into the first threaded hole and the second threaded hole, the first connecting plate moves toward the side closer to the second connecting plate, thereby reducing the diameter of the U-shaped fastening ring so that the U-shaped fastening ring can be fixedly installed on the tie rod seat.

[0017] Furthermore, the connecting rod is located between the machine head and the U-shaped fastening ring.

[0018] Furthermore, the side of the connecting rod facing the machine head abuts against the machine head, and the side of the connecting rod away from the machine head abuts against the U-shaped fastening ring.

[0019] Furthermore, one end of the connecting rod has an abutment plane, which abuts against the driving end of the driving assembly.

[0020] As can be seen from the above technical solution, the carpet overlocking machine with lifting foot of this utility model, by setting a first mounting column and a connecting rod with a first mounting hole and a second mounting hole, allows the first mounting hole of the connecting rod to be inserted into the pull rod seat, and the second mounting hole of the connecting rod to be inserted into the first mounting column. Finally, the whole installation is completed by installing the other end of the connecting rod onto the pull rod seat. This setting reduces the number of parts, lowers the assembly difficulty and the precision requirements of the parts, not only making it easier for non-professionals to install, but also reducing malfunctions caused by misalignment. On the other hand, the drive component is directly installed on the connecting rod, so the drive core can be accessed without disassembling multiple related parts during maintenance, greatly shortening downtime for maintenance, and ultimately improving equipment stability and production efficiency to meet production needs.

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0034] For ease of understanding, in this application, the observer faces the appendix Figure 2 When observing, the left side of the observer is designated as front, the right side as back, the front of the observer as left, the back of the observer as right, the top of the observer as up, and the bottom of the observer as down. It should be noted that the terms "front end", "rear end", "left side", "right side", "middle", "above", and "below" in the text indicate the orientation or positional relationship based on the accompanying drawings. They are only for the purpose of clearly describing this utility model and do not indicate or imply that the structure or component referred to must have a specific orientation or be constructed in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0035] Please refer to the following: Figures 1 to 5 This embodiment provides a carpet overlocking machine with a lifting foot, including a machine head 100, a first mounting post 120, a connecting rod 200, a drive assembly 300, and a connecting rod 400. A pull rod seat 110 extends from one side of the machine head 100. The first mounting post 120 is disposed on one side of the machine head 100. The connecting rod 200 has a first mounting hole 210 and a second mounting hole 220. The first mounting hole 210 is correspondingly disposed with the pull rod seat 110, and the pull rod seat 110 and the connecting rod 200 are rotatably connected. The second mounting hole 220 is correspondingly disposed with the first mounting post 120. The drive assembly 300 is mounted on the connecting rod 200. One end of the connecting rod 400 is drivenly connected to the drive assembly 300, and the other end of the connecting rod 400 is connected to the pull rod seat 110.

[0036] As can be seen, the carpet overlock machine with lifting foot in this embodiment, by setting a first mounting post 120 and a connecting rod 200 with a first mounting hole 210 and a second mounting hole 220, allows the first mounting hole 210 of the connecting rod 200 to be inserted into the pull rod seat 110, and the second mounting hole 220 of the connecting rod 200 to be inserted into the first mounting post 120. Finally, the overall installation is completed by installing the other end of the connecting rod 400 onto the pull rod seat 110. This setting reduces the number of parts, lowers the assembly difficulty and the precision requirements for component matching, and not only makes it convenient for non-professionals to install, but also reduces malfunctions caused by matching problems. On the other hand, the drive component 300 is directly installed on the connecting rod 200, so the drive core can be accessed without disassembling multiple related components during maintenance, which greatly shortens the downtime for maintenance and ultimately improves the stability and production efficiency of the equipment to meet production needs.

[0037] In this embodiment, a bearing 111 is fitted onto the pull rod seat 110. The inner ring of the bearing 111 is connected to the pull rod seat 110, and the outer ring of the bearing 111 is connected to the inner wall of the first mounting hole 210, so that the pull rod seat 110 and the connecting rod 200 are rotatably connected. The bearing 111 can be a ball bearing in the prior art. By fitting the bearing 111 onto the pull rod seat 110 and connecting the inner ring of the bearing 111 to the pull rod seat 110 and the outer ring to the inner wall of the first mounting hole 210 of the connecting rod 200, the direct friction between the pull rod seat 110 and the connecting rod 200 can be converted into rolling friction inside the bearing 111, which greatly reduces the wear generated when the two rotate relative to each other and extends the service life of the components. On the other hand, the characteristics of rolling friction can reduce rotational resistance, making the relative rotation of the pull rod seat 110 and the connecting rod 200 smoother and more stable, avoiding the problem of jamming or reduced transmission accuracy caused by uneven frictional resistance, further ensuring the smoothness of the lifting presser foot action, and indirectly improving the working reliability of the overlock machine.

[0038] In this embodiment, the first mounting post 120 and the pull rod seat 110 are arranged in parallel. By setting the first mounting post 120 and the pull rod seat 110 in a parallel state, the connecting rod 200 can be connected between the two in a more regular and stable manner. This ensures that when the drive component 300 drives the pull rod seat 110 to rotate through the connecting rod 400, the direction of force transmission is more accurate and smooth, reducing the risk of jamming or component misalignment during the transmission process. This further ensures the stability of the lifting press foot action and also provides a clearer positioning reference for subsequent component assembly, reducing the difficulty of alignment during assembly.

[0039] In this embodiment, the first mounting hole 210 and the second mounting hole 220 are located on the same plane. This arrangement ensures that the connection point between the connecting rod 200 and the pull rod seat 110, as well as the connection point between the first mounting post 120 of the connecting rod 200, are in the same plane. This ensures that the connecting rod 200 will not twist or deflect when subjected to force due to the holes not being in the same plane, thereby improving the stability and force balance of the overall structure of the connecting rod 200, ensuring the accuracy and smoothness of the lifting and pressing foot action, and providing a unified reference surface for the processing and assembly of components, reducing the error risk during manufacturing and assembly.

[0040] In this embodiment, the connecting rod 200 is provided with a first opening 230 so that the second mounting hole 220 is provided in a U-shaped hole with one side open, and a first elastic claw 240 and a second elastic claw 250 are formed on both sides of the opening.

[0041] This design eliminates the need for complete disassembly of the first mounting post 120 or complex alignment of the connecting rod 200. Users can directly engage the second mounting hole 220 with the first mounting post 120, significantly simplifying the assembly process of the connecting rod 200 and the first mounting post 120. At the same time, the clamping action of the elastic claws provides stable fixation to the first mounting post 120 after assembly, preventing loosening of the connection. Furthermore, during subsequent maintenance, the connecting rod 200 and the first mounting post 120 can be quickly separated by opening the elastic claws, reducing the difficulty and time cost of disassembly and assembly.

[0042] In this embodiment, the first mounting post 120 includes a rod 121 and a mushroom head 122. The front end of the rod 121 is connected to the machine head 100, and the mushroom head 122 is disposed at the end of the rod 121. The first elastic claw 240 and the second elastic claw 250 are used to pass through the mushroom head 122 and clamp the rod 121.

[0043] This configuration, in conjunction with the first elastic claw 240 and the second elastic claw 250 of the connecting rod 200, allows the first elastic claw 240 and the second elastic claw 250 to pass through the mushroom head 122 and stably clamp the rod part 121 during assembly. This not only prevents the connecting rod 200 from falling off the first mounting post 120 during use, ensuring the reliability of the connection, but also simplifies the assembly process between the connecting rod 200 and the first mounting post 120. Furthermore, during subsequent disassembly and maintenance, the elastic claws can be used to separate the rod, thus balancing connection stability and ease of assembly and disassembly.

[0044] In this embodiment, a U-shaped fastening ring 410 is provided at the other end of the connecting rod 400. A first connecting plate 411 and a second connecting plate 413 are provided at opposite ends of the opening of the U-shaped fastening ring 410. A first threaded hole 412 is provided on the first connecting plate 411, and a second threaded hole 414 is provided on the second connecting plate 413. By inserting and tightening bolts into the first threaded hole 412 and the second threaded hole 414, the first connecting plate 411 moves toward the side closer to the second connecting plate 413, thereby reducing the diameter of the U-shaped fastening ring 410 so that the U-shaped fastening ring 410 can be fixedly installed on the tie rod seat 110.

[0045] By providing a U-shaped fastening ring with a first connecting plate 411 and a second connecting plate 413 at the other end of the connecting rod 400, the bolts can be inserted into the first threaded hole 412 of the first connecting plate 411 and the second threaded hole 414 of the second connecting plate 413 and tightened. This reduces the diameter of the U-shaped fastening ring and allows for fixation to the tie rod seat 110 without requiring complex processing of the tie rod seat 110 or the use of special connectors, significantly reducing the assembly difficulty of the connecting rod 400 and the tie rod seat 110. At the same time, the bolt tightening method allows for flexible adjustment of the clamping force of the fastening ring, ensuring a firm connection and preventing loosening, while also adapting to tie rod seats 110 of different diameters, improving the versatility of the components. Subsequent disassembly and maintenance only require loosening the bolts for separation, making the operation convenient and preventing damage to the tie rod seat 110.

[0046] Preferably, the connecting rod 200 is located between the machine head 100 and the U-shaped fastening ring 410. By placing the connecting rod 200 between the machine head 100 and the U-shaped fastening ring, the three are arranged in an orderly manner along the axial direction of the tie rod seat 110, avoiding overlap or interference of components in the radial space, optimizing the structural layout of the side of the overlock machine, and making the overall structure more compact. At the same time, this arrangement allows the fixing force of the U-shaped fastening ring on the tie rod seat 110 and the supporting force of the connecting rod 200 on the tie rod seat 110 to cooperate in the axial direction, reducing the shaking of the tie rod seat 110 caused by force offset, further ensuring the stability of the drive assembly 300 when driving the tie rod seat 110 to rotate through the connecting rod 400, and indirectly improving the accuracy of the presser foot lifting action.

[0047] Preferably, the side of the connecting rod 200 facing the machine head 100 abuts against the machine head 100, and the side of the connecting rod 200 away from the machine head 100 abuts against the U-shaped fastening ring 410.

[0048] Specifically, by having the side of the connecting rod 200 facing the machine head 100 abut against the machine head 100 and the side away from the machine head 100 abut against the U-shaped fastening ring, the connecting rod 200 is firmly restrained between the machine head 100 and the U-shaped fastening ring. This completely eliminates the space for the connecting rod 200 to move along the axial direction of the tie rod seat 110, preventing loosening of the connection or collision of parts due to axial displacement during equipment operation. At the same time, this bidirectional abutting structure allows the connecting rod 200, the machine head 100, and the U-shaped fastening ring to form a stable whole, ensuring that the force transmitted by the drive assembly 300 can act more directly and without loss on the tie rod seat 110, further improving the stability and response accuracy of the lifting pressure foot action, and also reducing additional wear caused by component displacement.

[0049] In this embodiment, one end of the connecting rod 200 has an abutment plane 420, which abuts against the driving end of the driving assembly 300.

[0050] Specifically, by forming an abutting plane 420 at one end of the connecting rod 200 and abutting the driving end of the driving assembly 300, the driving force output by the driving assembly 300 can be uniformly transmitted to the connecting rod 200 through the plane contact. Preferably, the driving assembly 300 is an electromagnet structure and the connecting rod 200 is an adsorbable metal material, so that the connecting rod 200 can be controlled to drive the pull rod seat 110 to rotate by adsorbing the connecting rod 200 through energization.

[0051] In other possible implementations, the drive assembly 300 may be a structure such as an electric actuator, a pneumatic cylinder, or a hydraulic cylinder, and such a simple replacement should also be within the scope of protection of this utility model.

[0052] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0053] This utility model discloses a carpet overlocking machine with a lifting foot. It features a first mounting post 120 and a connecting rod 200 with a first mounting hole 210 and a second mounting hole 220. The first mounting hole 210 of the connecting rod 200 is inserted into a pull rod seat 110, and the second mounting hole 220 of the connecting rod 200 is inserted into the first mounting post 120. Finally, the entire assembly is completed by installing the other end of the connecting rod 400 onto the pull rod seat 110. This design reduces the number of parts, lowers assembly difficulty and component precision requirements, making installation easier for non-professionals and reducing malfunctions caused by misalignment. Furthermore, the drive assembly 300 is directly mounted on the connecting rod 200, allowing access to the drive core without disassembling multiple related components during maintenance, significantly reducing downtime and ultimately improving equipment stability and production efficiency to meet production needs.
