Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of sewing machine components, specifically a needle plate and a sewing machine thereof. Background Technology
[0002] A sewing machine is a machine that uses one or more sewing threads to create one or more stitches on fabric, interweaving or sewing together one or more layers of fabric. Sewing machines are generally equipped with a needle plate for sewing. Currently, there is a need to add a transparent elastic band to the lining of underwear to improve its elasticity and shaping effect. However, the needle plate on current sewing machines is prone to misalignment of the transparent rubber due to its softness when feeding and sewing it to the designated sewing position on the underwear lining. This results in poor sewing quality. Summary of the Invention
[0003] The purpose of this utility model is to address the aforementioned problems in existing technologies and propose a solution.
[0004] A needle plate and its sewing machine have the advantage of better sewing effect.
[0005] The objective of this utility model can be achieved through the following technical solution: a needle plate, comprising:
[0006] plate body,
[0007] The plate has pinholes for a machine needle to pass through.
[0008] The plate has at least one through slot; the through slot is used for the movement of the feed teeth;
[0009] The plate is provided with a channel, the outlet of which is aligned with the pinhole, and the channel is used to transport the strip material.
[0010] In the aforementioned needle plate, the channel is located on one side of the through groove, and the channel is arranged parallel to the through groove.
[0011] In the aforementioned needle plate, the inlet of the channel is lower than the supporting surface of the plate.
[0012] In the aforementioned needle plate, a support portion extends from the lower wall of the channel, the support portion being used to support the strip material.
[0013] In the aforementioned needle plate, the plate body is provided with a notch that faces the channel and is in contact with the supporting part.
[0014] In the aforementioned needle plate, the supporting portion and the sidewall of a portion of the notch form a guide groove.
[0015] In the aforementioned needle plate, the plate body has a protruding plate portion, the needle hole is disposed on the protruding plate portion, and a guide portion is disposed on the channel-facing side of the protruding plate portion, the guide portion being used to guide the strip material to the needle hole position.
[0016] In the aforementioned needle plate, the plate body is provided with a guide portion, which is arranged between the needle hole and the channel outlet. One end of the guide portion is not higher than the lower wall of the channel and is close to the channel, while the other end is higher than the lowest position of the guide portion.
[0017] A sewing machine including the aforementioned needle plate.
[0018] Compared with the prior art, the advantages of this utility model are: by setting a channel on the plate, with the outlet of the channel aligned with the needle hole, the transparent rubber is fed into the channel. Both the plate and the channel are made of stainless steel, which is relatively hard. The transparent rubber is guided by the channel, which helps to play a good guiding role and is not prone to left or right deviation. This enables the transparent rubber to be sewn onto the underwear lining, and it is convenient to sew, with better sewing effect and higher quality. Attached Figure Description

[0022] In the figure, 2 is the plate; 22 is the through groove; 23 is the channel; 41 is the bearing part; 42 is the notch; 43 is the guide groove; 5 is the protruding plate part; 51 is the guide part; and 6 is the guide part. Detailed Implementation
[0023] 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 a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.
[0024] like Figures 1 to 3 As shown, a needle plate includes:
[0025] Plate body 2,
[0026] The plate 2 has a pinhole for a machine needle to pass through;
[0027] The plate 2 has at least one through groove 22; the through groove 22 is used for the movement of the feed tooth;
[0028] The plate 2 is provided with a channel 23, the outlet of the channel 23 is aligned with the pinhole, and the channel 23 is used to transport the strip material.
[0029] The strip material in this invention is transparent rubber, which is existing technology.
[0030] Using the above structure, a channel 23 is provided on the plate 2, and the outlet of the channel 23 is aligned with the needle hole. Transparent rubber is fed into the channel 23. Both the plate 2 and the channel 23 are made of stainless steel, which is relatively hard. The transparent rubber is guided by the channel 23 and is not prone to left or right deviation. This helps to play a good guiding role, so that the transparent rubber can be sewn onto the underwear lining. It is also convenient to sew, and the sewing effect is better and the quality is better.
[0031] Specifically, such as Figures 1 to 3 As shown, the channel 23 is located on one side of the through groove 22, and the channel 23 is arranged parallel to the through groove 22.
[0032] With the above structure, the parallel arrangement of channel 23 and through groove 22 facilitates the parallel conveying and movement of the feed teeth and strip materials, making sewing easier.
[0033] like Figures 1 to 3 As shown, the inlet of the channel 23 is lower than the supporting surface of the plate 2.
[0034] like Figures 1 to 3 As shown, a support portion 41 extends from the lower wall of the channel 23, and the support portion 41 is used to support the strip material. By providing the support portion 41, it is beneficial to better support the transparent rubber, resulting in a good support effect.
[0035] like Figures 1 to 3 As shown, the plate 2 is provided with a notch 42 that is recessed toward the channel 23, and the notch 42 is connected to the supporting part 41.
[0036] The supporting part 41 and the side wall of part of the notch 42 form a guide groove 43.
[0037] By setting the notch 42 and the guide groove 43, it is convenient for the transparent rubber to be inserted into and penetrate into the bearing part 41 and the channel 23, which has a good guiding effect.
[0038] like Figures 1 to 3As shown, the plate 2 has a protruding plate portion 5, and the pinhole is disposed on the protruding plate portion 5. A guide portion 51 is provided on the side of the protruding plate portion 5 facing the channel 23. The guide portion 51 is used to guide the strip material to the pinhole position. By providing the protruding plate portion 5, it is convenient to guide the transparent rubber to the pinhole position.
[0039] like Figures 1 to 3 As shown, the plate 2 is provided with a guide portion 6, which is arranged between the needle hole and the outlet of the channel 23. One end of the guide portion 6 is not higher than the lower wall of the channel 23 and is close to the channel 23, while the other end is higher than the lowest position of the guide portion 51. A sewing machine includes the above-mentioned needle plate. By providing the guide portion 6, with one end not higher than the lower wall of the channel 23 and close to the channel 23, and the other end higher than the lowest position of the guide portion 51, it is beneficial to guide the transparent rubber from a low position to a high position, providing a good guiding effect and facilitating sewing.
