Description

Technical Field

[0001] This utility model relates to the field of sewing machine teeth technology, specifically a sewing machine teeth assembly. Background Technology

[0002] The sewing machine feed dog is a key component in a sewing machine used to feed fabric. Through an elliptical motion trajectory, it combines the back-and-forth movement of the feed shaft and the up-and-down movement of the feed dog shaft to ensure that the fabric is fed smoothly and continuously. During use, the feed dog needs to be maintained and cared for to reduce the residue of foreign objects and extend its service life.

[0003] However, in the use of some existing dental frames, the gaps between each tooth are easily blocked by foreign objects such as fibers and dust in the fabric, which reduces the friction between the component and the fabric. This not only affects the pushing of the component on the fabric during use, but also makes it inconvenient to clean foreign objects frequently, thus reducing the applicability of the component. Utility Model Content

[0004] The purpose of this invention is to provide a sewing machine teeth assembly to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sewing machine feeder assembly, including a mounting bracket and positioning holes formed on its surface, and further comprising:

[0006] A needle slot is provided at the top of the mounting frame, and a fixing plate is fixedly connected to the top of the mounting frame. A toothed mechanism with a split design is installed on the top of the fixing plate to reduce foreign matter residue.

[0007] A discharge chute located on the top of a fixed plate, which guides impurities through its shape.

[0008] Preferably, the tooth mechanism includes a fixed tooth fixed to the top of the fixed plate, a material clamping groove is provided on one side of the fixed tooth, and support seats are fixedly connected to both sides of the bottom of the fixed tooth.

[0009] Preferably, one side of the fixing tooth is designed with an inclined structure, and the inner wall of the material clamping groove is designed with an arc shape. The material clamping groove is used in conjunction with the fixing tooth.

[0010] Preferably, the surface of the fixing plate is provided with a connecting plate, and the surface of the connecting plate is fixedly connected to the surface of the fixing tooth.

[0011] Preferably, the number of discharge troughs is several, and their inner walls are designed with an inclined structure.

[0012] Preferably, the number of fixing plates is three, the inner wall of the needle-threading groove is designed with an inclined structure, and the needle-threading groove is used in conjunction with the fixing plates.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention, through the cooperation of a fixing plate, allows each toothed mechanism to be separated individually, enabling impurities to fall and be discharged from the gap between two toothed mechanisms. This reduces the possibility of impurities clogging the gap between the two toothed mechanisms and affecting the fabric movement. Furthermore, with the cooperation of the discharge groove and the needle insertion groove, impurities and other foreign objects can be discharged in a timely manner, further improving the cleanliness of the component itself and effectively enhancing its applicability. This solves the problem that foreign objects affect the fabric movement and have poor applicability in existing components. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4As shown, a sewing machine toother assembly includes a mounting frame 1. The mounting frame 1 has positioning holes 2 on its surface, which can be easily installed using bolts, making assembly and disassembly easier. The top of the mounting frame 1 has a needle groove 3, and three fixing plates 4 are fixedly connected to the top of the mounting frame 1. The inner wall of the needle groove 3 has an inclined structure design. The needle groove 3 works in conjunction with the fixing plates 4, allowing impurities to fall into the needle groove 3 and be effectively discharged through its internal shape, thus reducing the residue of foreign matter inside the needle groove 3. The positions of the fixing plates 4 and the needle groove 3 correspond to each other, allowing impurities discharged from the surface of the fixing plates 4 to be discharged through the needle groove 3. A toothed mechanism 6 is installed on the top of the fixing plates 4, which increases the stability after connection with the fabric, allowing the assembly to move the fabric during swinging.

[0022] The top of the fixed plate 4 is provided with a discharge groove 5. There are several discharge grooves 5, and their inner walls are designed with an inclined structure. Under this function, when impurities fall on the surface of the tooth mechanism 6, they can be discharged from the surface of the fixed plate 4 through the guide of the discharge groove 5, thereby reducing the situation where impurities remain on the top of the fixed plate 4. This effectively reduces the situation where impurities block the component and affect the movement of the fabric, and also reduces the residue of impurities between each tooth mechanism 6.

[0023] The toothed mechanism 6 includes several fixed teeth 61 fixed to the top of the fixed plate 4. One side of each fixed tooth 61 has an inclined design with an angle of 45 degrees. This increases the friction between the fixed teeth 61 and the fabric, thereby moving the fabric. A material-catching groove 62 is provided on one side of each fixed tooth 61. The inner wall of the material-catching groove 62 has an arc-shaped design. The material-catching groove 62 works in conjunction with the fixed teeth 61. With the cooperation of the material-catching groove 62, even when the fixed teeth 61 experience significant wear, their angle remains below 45 degrees. Furthermore, the material-catching groove 62 causes the fixed teeth 61 to form a hook shape, further increasing the friction between them and the fabric, thus allowing the fabric to move smoothly. The component is designed to prevent slippage, effectively improving its stability during use. Support seats 63 are fixedly connected to both sides of the bottom of the fixing tooth 61. The surface of the support seats 63 is fixedly connected to the surface of the fixing plate 4, providing oblique support for the fixing tooth 61. This prevents the fixing tooth 61 from tilting or falling off easily when it is pushed against the fabric, thus improving its stability during use. A connecting plate 7 is provided on the surface of the fixing plate 4, and its surface is fixedly connected to the surface of the fixing tooth 61. This allows the fixing teeth 61 to be connected through the connection of the connecting plate 7, ensuring that each fixing tooth 61 can be interconnected, thereby reducing the possibility of one fixing tooth 61 falling off.

[0024] Working principle: First, the component is installed by bolts and positioning holes 2. When in use, the component can be swung to push the fabric. With the cooperation of the fixing teeth 61 and the material groove 62, the fixing teeth 61 can make closer contact with the fabric, thus making the fabric move more smoothly. During the movement of the fabric, impurities will adhere to the surface of the fixing teeth 61. Under the action of weight, they will fall through the space between the two fixing teeth 61 and then be discharged from the needle groove 3 with the cooperation of the discharge groove 5. This reduces the possibility of impurities clogging the gap between the two fixing teeth 61 and effectively improves the pushing effect of the component on the fabric.
