Description

Technical Field

[0001] This utility model relates to the field of embroidery machine technology, and in particular to an installation structure for a heavy-duty needle bar holder. Background Technology

[0002] To improve work efficiency, existing embroidery machines typically have multiple embroidery heads arranged side by side, connected to the frame via a connecting shaft. Each head corresponds to a needle bar holder. Given the diverse types of embroidery, a single head often houses multiple embroidery devices, such as cord embroidery, bead embroidery, and sequin embroidery. To achieve various embroidery techniques while minimizing the distance between embroidery heads, different types of embroidery devices are usually connected to the same side of the needle bar holder. Embroidery devices, such as five-bead feeders, are large and heavy. Placing them on only one side of the needle bar holder leads to excessive load, causing the needle bar holder to wobble easily during operation. Furthermore, excessive load on one side can deform the needle bar holder, shortening its lifespan. This is especially true for needle bars with small head spacing and fewer stitches, where the size is smaller but the weight is greater, making deformation even more likely. Utility Model Content

[0003] To address the problems of the prior art, this utility model provides an installation structure for a heavy-duty needle bar holder, which connects multiple needle bar holders through a connecting structure to share the load and reduce the shaking and deformation of the needle bar holder.

[0004] The technical solution adopted is as follows:

[0005] A heavy-duty needle bar holder mounting structure includes several machine heads arranged side by side on a machine frame, each machine head having a corresponding needle bar holder. The needle bar holder can slide laterally relative to the corresponding machine head. It also includes a first connecting structure that individually connects several needle bar holders. The needle bar holder can slide laterally relative to the first connecting structure. Lateral sliding refers to the needle bar holder sliding in the direction of movement when switching different needles into working positions.

[0006] Furthermore, the first connecting structure includes a connecting shaft for connecting the needle bar holder, and the needle bar holder is provided with a through hole for the connecting shaft to pass through.

[0007] Furthermore, the first connecting structure includes a connecting shaft for connecting the needle bar holder, and each needle bar holder is provided with at least one connecting block, which is slidably disposed on the connecting shaft.

[0008] Furthermore, each needle bar frame is equipped with a connecting block, with an embroidery device installed on one side of the needle bar frame and a connecting block installed on the other side.

[0009] Furthermore, the connecting block is provided with a connecting hole that mates with the connecting shaft.

[0010] Furthermore, a second connecting structure is provided between the connecting block and the needle bar holder.

[0011] Furthermore, the second connecting structure includes a groove on the connecting block that mates with the needle bar frame side plate, and also includes fixing bolts for fixing the connecting block to the needle bar frame.

[0012] Furthermore, a sliding assembly is provided between the needle bar holder and the corresponding machine head.

[0013] Furthermore, the sliding assembly includes a slider on the machine head and a slide rail on the needle bar frame that cooperates with the slider.

[0014] Furthermore, the sliding assembly includes a slide rail on the machine head and a slider on the needle bar frame that cooperates with the slide rail.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This utility model provides an installation structure for a heavy-duty needle bar holder. A first connecting structure is provided on several needle bar holders arranged side-by-side to connect them, distributing some of the force on the needle bar holders and reducing deformation and swaying caused by excessive load. The needle bar holders connected by the first connecting structure have better balance, are less prone to swaying, have stronger load-bearing capacity, and reduce deformation. The needle bar holders can be directly connected via a connecting shaft, or, preferably, connected to the connecting shaft via a connecting block. Only the connecting block needs to be machined separately, simplifying manufacturing. The needle bar holders can slide relative to the connecting shaft, and their movement is not affected during color changes. Attached Figure Description

[0022] The present invention will be further described below with reference to specific embodiments.

[0023] refer to Figure 1-5 A heavy-duty needle bar holder mounting structure includes several machine heads 1 arranged side-by-side on a frame, each machine head 1 corresponding to a needle bar holder 2. The needle bar holder 2 can slide laterally relative to its corresponding machine head 1. The structure also includes a first connecting structure 3 that individually connects the several needle bar holders. The needle bar holder 2 can slide laterally relative to the first connecting structure 3. Lateral sliding refers to the needle bar holder sliding in the direction of movement for switching different needles into their working positions. The sliding of the needle bar holder relative to the first connecting structure 3 does not affect the needle switching function.

[0024] In existing embroidery machines, a heavy embroidery device is typically located on one side of the needle bar frame. This is especially problematic for machines with small head spacing and low stitch counts, where the space between adjacent machine heads is limited. With the embroidery device positioned on one side of the needle bar frame, the frame is overloaded and prone to wobbling during operation. Excessive unilateral load can also cause deformation of the needle bar frame. Furthermore, embroidery machines with low stitch counts are even more susceptible to deformation due to their smaller size. Therefore, a first connecting structure 3 is installed to connect several needle bar frames 2, balancing some of the force, reducing deformation and wobbling, and extending the lifespan of the needle bar frames. Needle bar frames connected by the first connecting structure 3 exhibit better balance, are less prone to wobbling, have stronger load-bearing capacity, and reduce deformation.

[0025] In one embodiment, the first connecting structure 3 includes a connecting shaft 301 connecting the needle bar holder. The needle bar holder 2 has a through hole (not shown in the figure) through which the connecting shaft 301 passes, and the needle bar holder 2 can slide relative to the connecting shaft 301. The connecting shaft connects to the needle bar holder, and several needle bars are all on the same connecting shaft, which plays a certain positioning role for the needle bar holder and reduces the shaking of the needle bar holder.

[0026] In another embodiment, the first connecting structure 3 includes a connecting shaft 301 connecting the needle bar frame. Each needle bar frame 2 is provided with at least one connecting block 302, which is slidably mounted on the connecting shaft 301. The connecting block 302 is mounted on the needle bar frame 2, and the needle bar frame 2 can also slide relative to the connecting shaft 301. Preferably, each needle bar frame is provided with a connecting block 302. An embroidery device is installed on one side of the needle bar frame, and the connecting block 302 is installed on the other side. The embroidery device and the connecting block 302 are located on different sides, so they do not interfere with each other, facilitating the installation of the embroidery device and the connecting block. The connecting block 302 is provided with a connecting hole 4 that mates with the connecting shaft 301, allowing it to slide relative to the connecting shaft 301. By connecting the needle bar frame and the connecting shaft through the connecting block 302, there is no need to drill holes in the needle bar frame; only the connecting block 302 needs to be machined separately. This is more convenient for embroidery machines with small head spacing.

[0027] A second connecting structure 6 is provided between the connecting block 302 and the needle bar holder 2. The second connecting structure 6 includes a groove 601 on the connecting block 302 that mates with the side plate of the needle bar holder 2, and a fixing bolt 602 that fixes the connecting block 302 to the needle bar holder 2. The connecting block 302 has a groove that mates with the side plate of the needle bar holder 2. The groove is engaged with the side plate 7 of the needle bar holder 2, and the connecting block 302 is fixed to the needle bar holder 2 by the fixing bolt 602.

[0028] A sliding assembly 5 is provided between the needle bar holder 2 and the corresponding machine head. The needle bar holder 2 can slide relative to the machine head, switching different needles to enter the working position for embroidery. The sliding assembly 5 includes a slider 501 on the machine head and a slide rail 502 on the needle bar holder that cooperates with the slider. Alternatively, the sliding assembly 5 includes a slide rail 502 on the machine head and a slider 501 on the needle bar holder that cooperates with the slide rail. It is only necessary to ensure that the needle bar holder can slide laterally relative to the machine head 1.

[0029] The above description is only an optional embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
