Description

Technical Field

[0001] This utility model relates to the field of sewing machine technology, and in particular to a sewing machine needle positioning device. Background Technology

[0002] Currently, conventional sewing machines on the market lack positioning tools during assembly, even though the needles are accurately assembled. Therefore, needle adjustments need to be made while the machine is running. This requires disassembly and adjustment, which is not convenient and increases manpower and material resources, thus increasing labor costs. Furthermore, adjustments rely on human experience, which can lead to large errors and further increases labor costs. Utility Model Content

[0003] This invention aims to overcome the shortcomings of the prior art by providing a sewing machine needle positioning device. The device allows for positioning adjustment during needle assembly, ensuring needle positioning accuracy and enabling multi-needle positioning.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: This sewing machine needle positioning device includes a needle, a needle positioning tool for positioning the needle is provided on the needle, and a plurality of needle positioning holes are provided on the needle positioning tool, the positions of the needle positioning holes corresponding to and matching the needle.

[0005] Furthermore, the cross-section of the needle positioning device is set in a rectangular shape.

[0006] Furthermore, the number of needle positioning holes is the same as the number of needles.

[0007] Furthermore, the number of needle positioning holes is two.

[0008] Furthermore, the corners of the needle positioning device are set in an arc shape.

[0009] Furthermore, a needle bar is connected to the needle.

[0010] The beneficial effects of this utility model are as follows: The sewing machine needle positioning device of this utility model has a reasonable structure. Positioning adjustment can be performed during needle assembly to ensure the positioning accuracy of the needle and the working accuracy of the sewing machine. It can also achieve the effect of multi-needle positioning, making it easy to check whether double or multiple needles are installed in place and to check whether the needle is deformed. It can be adjusted during needle assembly without subsequent adjustment, reducing manpower and material resources, lowering labor costs and production costs. It has good performance and is easy to promote. Attached Figure Description

[0013] Explanation of reference numerals in the attached diagram: needle 1, needle positioning device 2, needle positioning hole 3, needle bar 4. Detailed Implementation

[0014] The present invention will be further described below with reference to the accompanying drawings:

[0015] Referring to the attached diagram: This sewing machine needle positioning device includes a needle 1, which is used for sewing. The needle 1 is equipped with a needle positioning device 2 for positioning the needle 1. The needle positioning device 2 is used to check whether double or multiple needles are installed correctly and to check whether the needle is deformed. It can be adjusted during the assembly of the needle 1. The needle positioning device 2 is provided with several needle positioning holes 3, the positions of which correspond to and match the needle 1. In this way, the needle positioning device 2 can use the needle positioning holes 3 to match and position the needle 1. If the needle 1 is not installed correctly or is deformed, the needle 1 cannot match the needle positioning holes 3, and the error can be detected and adjusted until the needle 1 is installed correctly. The needle positioning device 2 makes it convenient to check whether double or multiple needles are installed correctly and to check whether the needle is deformed.

[0016] Furthermore, the needle positioning device 2 has a rectangular cross-section. This design facilitates positioning checks for dual or multiple needles.

[0017] Furthermore, the number of needle positioning holes 3 is the same as the number of needles. This setting can be applied to both dual-needle and multi-needle machines.

[0018] Furthermore, the number of needle positioning holes 3 is two. This setting, as... Figure 1 , Figure 2 As shown, in this embodiment, a dual-needle positioning and viewing method is used.

[0019] Furthermore, the corners of the needle positioning device 2 are set in an arc shape. This design facilitates manual operation of the needle positioning device 2.

[0020] Furthermore, a needle bar 4 is connected to the needle 1.

[0021] When using, such as Figure 1 , Figure 2 As shown, after the needle 1 is installed, the needle positioning tool 2 is used to position and match the needle positioning hole 3 with the needle 1. If the needle 1 is not installed in place, or the needle 1 is deformed, the needle 1 cannot match the needle positioning hole 3. The error can be checked and adjusted until the needle 1 is installed in place.

[0022] The features of this utility model embodiment are: positioning adjustment can be performed during needle assembly to ensure the positioning accuracy of the needle and the working accuracy of the sewing machine. It can also achieve the effect of multi-needle positioning, making it easy to check whether double or multiple needles are installed in place and to check whether the needle is deformed. It can be adjusted during needle assembly without subsequent adjustment, reducing manpower and material resources, lowering labor costs and production costs. It has good performance and is easy to promote.

[0023] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
