Description

Technical Field

[0001] The utility model relates to the technical field of embroidery machines, in particular to a mounting structure of a needle bar driving block. Background Art

[0002] The needle bar driver is a device used to drive the needle bar to move up and down. A drive block is usually provided on the needle bar driver to cooperate with the drive slot on the needle bar. After the drive block is inserted into the drive slot, it drives the needle bar to move up and down. The installation position of the existing needle bar drive block is usually fixed. Since the position of the needle bar drive block is fixed, the drive slot of the needle bar also needs to be set at the same installation height as the needle bar drive block and cannot be adjusted. In addition, there may be errors during processing and installation, resulting in position deviations. Summary of the invention

[0003] In order to solve the defects of the prior art, the utility model provides a mounting structure of a needle bar driving block, which can adjust the height of the driving block to match the needle bar, reduce errors, and facilitate adjustment.

[0004] The technical solutions adopted are as follows:

[0005] A mounting structure for a needle bar driving block comprises a driving block movable sleeve sleeved outside a needle bar driving shaft and a driving block mounting base for mounting the driving block. The driving block mounting base is height-adjustable and is arranged on the driving block movable sleeve.

[0006] Furthermore, the driving block movable sleeve includes an extension block extending outward.

[0007] Furthermore, the driving block mounting base includes a connecting block mounted corresponding to the extending block and a mounting block for mounting the driving block.

[0008] Furthermore, the connection block is provided with a strip groove with adjustable height, or adjustment holes with multiple holes.

[0009] Furthermore, the extension block is provided with a screw hole and a corresponding screw, and the screw passes through the strip groove or the adjustment hole and is installed in the screw hole.

[0010] Furthermore, at least one strip-shaped groove may be provided.

[0011] Furthermore, the mounting block is provided with a mounting shaft, and the driving block is mounted on the mounting shaft.

[0012] Compared with the prior art, the beneficial effects produced by the utility model are:

[0013] The utility model provides an installation structure for a needle bar driving block, wherein the driving block is installed on a driving block installation base, the driving block installation base is height-adjustable and installed on a driving block movable sleeve, and a driving block movable sleeve fixed sleeve is arranged outside the needle bar driving shaft. Since the height of the installation base is adjustable, the position of the driving block can be adjusted to match the driving groove on the needle bar, which can improve the fault tolerance rate during processing, eliminates the need to adjust the position of the needle bar, reduces errors, and is easy to use.

[0015] Figure 2 This is a disassembly diagram of the utility model;

[0016] Figure 3 It is a bottom view of the utility model;

[0017] Among them, the driving block 1, the driving block movable sleeve 2, the extension block 201, the strip groove 3, the screw 4, the driving block mounting base 5, the connecting block 501, the mounting block 502, the screw hole 6, and the mounting shaft 7. DETAILED DESCRIPTION

[0018] The present invention is further described below in conjunction with specific embodiments.

[0019] refer to Figure 1 , 2 3. A mounting structure for a needle bar driving block, comprising a driving block movable sleeve 2 sleeved on the needle bar driving shaft (not shown) and a driving block mounting base 5 for mounting a driving block 4, wherein the driving block mounting base 5 is height-adjustable and is arranged on the driving block movable sleeve 2.

[0020] Furthermore, the driving block movable sleeve 2 is installed outside the needle bar driving shaft and can be driven to move up and down. The driving block cooperates with the needle bar to drive the needle bar to move up and down.

[0021] Furthermore, the driving block movable sleeve 2 includes an extension block 201 extending outward.

[0022] Furthermore, the driver block mounting base 5 comprises a connection block 501 mounted corresponding to the extension block 201 and a mounting block 502 for mounting the driver block 1. The connection block 501 is fitted with the extension block 201 and is mounted in a fitted manner with the extension block 201.

[0023] Furthermore, the connecting block is provided with a strip groove 3 with adjustable height, or an adjustment hole with multiple holes can be set. The extension block 201 is provided with a screw hole 6 and a corresponding screw 4, and the screw 4 passes through the strip groove 3 or the adjustment hole and is installed in the screw hole 6. Since the screw 4 has enough space to move in the strip groove 3, the installation height of the drive block mounting base 5 can be adjusted up and down, and fixed by the screw 4 after the height is adjusted. The drive block 1 is arranged on the mounting block 502, which is equivalent to the height of the drive block 1 being adjustable. By adjusting the height of the drive block 1 to match the drive groove on the needle bar, the fault tolerance rate can be further improved, the error can be reduced, and the drive block 1 can be accurately embedded in the drive groove to complete the drive of the needle bar.

[0024] By disassembling and installing through screw 4, the position of the driving block can be adjusted at any time to match the needle bar.

[0025] Further, at least one strip groove 3 may be provided. Preferably, two strip grooves 3 are provided, which is more firmly fixed.

[0026] Furthermore, the mounting block 502 is provided with a mounting shaft 7, and the driving block is mounted on the mounting shaft 8. The driving block 1 can rotate relative to the mounting shaft, thereby disengaging from or engaging with the needle bar.

[0027] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
