Description

Technical Field

[0001] This utility model relates to the field of automotive seat manufacturing technology, and in particular to an auxiliary device for sewing the hanging brace fabric of automotive seat covers. Background Technology

[0002] The slings (also known as straps or suspension straps) of car seat covers are auxiliary materials inside the seat covers used to secure and support the fabric, and are usually made of high-strength fabric or nylon straps.

[0003] When sewing the hanging reinforcement fabric for car seat covers, folding and sewing are required. During the folding process, a folding auxiliary device is needed. Existing folding auxiliary devices usually use roller sets with shaping channels between the roller sets. The folded hanging reinforcement fabric enters the sewing machine head through the roller set channels for sewing, which can improve sewing efficiency.

[0004] Existing folding aids can only shape the object after folding, and cannot achieve rapid folding. Utility Model Content

[0020] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] 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 scope of protection of the present utility model.

[0022] Example 1

[0023] like Figure 1-3 As shown, an auxiliary device for sewing the hanging brace fabric of an automobile seat cover includes an infeed guiding structure and an outfeed shaping structure. The infeed guiding structure includes a guide plate, and the outfeed shaping structure includes a base plate 203. The guide plate and the base plate 203 are distributed in parallel. The base plate 203 has a shaping channel, which includes a folded portion and a shaping portion distributed sequentially from the infeed end to the outfeed end. Specifically, the shaping channel includes two side plates 202 integrally formed on the base plate 203, forming a shaping channel between the two side plates 202. The distance between the two side plates 202 decreases sequentially from the infeed end to the outfeed end, thus forming a folded portion at the infeed end and a shaping portion at the outfeed end. The side plates 202 are also connected to... The buffer reinforcement structure includes an inner liner 201 integrally formed on the inner side of the side plate 202. There is a buffer gap between the inner liner 201 and the side plate 202. The inner liner 201 is suspended diagonally downwards, which makes the shaping channel a structure with a wide inlet end, a narrow outlet end, a narrow bottom end, and a wide top end. The end of the hanging rod cloth is placed downwards into the shaping part and then pushed forward. The hanging rod cloth is automatically folded and sent out after passing through the shaping channel, which is convenient for folding and shaping. Since the inner liner 201 is suspended diagonally downwards, the buffer gap at the bottom end is larger, which results in better buffer elasticity. During use, it can form elastic buffer and reduce the lateral extrusion force generated between the hanging rod cloth and the side plate 202 during the process of being pulled and moved.

[0024] The reinforcing structure also includes a reinforcing plate 301 installed between the inner liner plate 201 and the base plate 203. A support plate 302 is integrally formed on the side of the reinforcing plate 301, extending into the buffer gap. When the lateral compressive force generated between the suspension cloth and the side plate 202 is too large during the tensioning and movement of the suspension cloth, the lower end of the inner liner plate 201 will swing to the lower end of the side plate 202, which may cause the side plate 202 to deform. Furthermore, the high-frequency and large-amplitude swing of the inner liner plate 201 will cause fatigue, thus affecting its service life. By supporting the lower end of the buffer gap with the support plate 302, the swing amplitude of the inner liner plate 201 can be limited, and the structural strength at the side plate 202 can also be improved, thereby increasing the service life.

[0025] The base plate 203 also has a connecting structure for connecting to a sewing machine. The connecting structure includes a connecting shaft hole 205 machined on the base plate 203 and a positioning hole 303 machined on the reinforcing plate 301 at a position corresponding to the connecting shaft hole 205. A connecting shaft that mates with the connecting shaft hole 205 can be installed on the sewing machine. The connecting shaft is inserted upward into the connecting shaft hole 205 and the positioning hole 303. The connecting shaft is connected to the connecting shaft hole 205 and the positioning hole 303 through clearance fit, which facilitates installation and allows the base plate 203 to rotate around the connecting shaft to reduce the lateral extrusion force generated between the suspension fabric and the side plate 202 during the process of being pulled and moved.

[0026] The base plate 203 is connected to a connecting plate 204 that mates with the guide plate. The guide plate is integrally formed with a pressing part 102 that mates with the reinforcing plate 301. The pressing part 102 extends to the end of the shaping channel, thereby making the bottom surface of the shaping channel flat. The guide plate includes a guide part 101, and the guide part 101 is also integrally formed with a connecting part 103 that mates with the connecting plate 204. The connecting part 103 is formed by bending and is bent to the lower side of the connecting plate 204. During use, the connecting part 103 mates with the sewing machine operating platform, and together with the connecting shaft, supports the automotive seat cover hanging rod sewing auxiliary device. By pressing the connecting part 103, the guide plate, the reinforcing plate 301, and the base plate 203 can be fixed together without additional welding, making installation convenient.

[0027] The guide plate, reinforcing plate 301, and base plate 203 are all made of stainless steel plate with a thickness of 3mm, which has high wear resistance and high corrosion resistance.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
