[0028] 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.

[0029] Example 1

[0030] In existing technologies, the reduced fabric production rate is due to the need for manual pressing of the fabric and the inability to quickly switch between different colored threads. This embodiment provides a sewing machine with dual-needle, dual-color functionality. Please refer to [reference needed]. Figures 1-7This sewing machine, featuring a double-needle, double-color function, automatically presses and tightens the fabric, thereby improving the processing stability and production quality of the fabric. It includes a sewing head 2 mounted on a frame 1. The sewing head 2 employs a double-needle, double-color structure, enabling rapid sewing of the fabric and improving sewing quality. A controller is installed at the top of the sewing head 2 to control the operation of relevant structures on the frame 1. The frame 1 is equipped with a fabric-folding and shrinking mechanism 3, and the sewing head 2 is equipped with a pressing and sewing mechanism 4 for quickly switching between different colored threads. The shrinking mechanism 3 automatically folds and picks up the processed fabric, accelerating the fabric production rate, while the pressing and sewing mechanism 4 secures the fabric, thus improving the stability of the sewing process.

[0031] In the fabric production process, in order to fix the fabric and improve the stability of the sewing process, the pressing and sewing mechanism 4 includes a transmission frame 41 installed on the machine frame 1. The transmission frame 41 is equipped with a mounting frame 42. The mounting frame 42 is equipped with two sets of cylinders 43. The cylinders 43 are symmetrically distributed on both sides of the mounting frame 42, which improves the stability of fixing the fabric. A connecting plate 44 is installed on the cylinder 43. A pressure plate 45 is installed on the connecting plate 44. The pressure plate 45 is made of aluminum alloy. Aluminum alloy has the functions of moisture resistance and corrosion resistance, which provides a certain degree of protection for the fabric. A cover 46 is installed on the outside of the machine head 2. A linkage rod 47 is installed on the outside of the cover 46. An auxiliary needle 48 is rotatably installed at one end of the linkage rod 47. A fixing component 49 is installed inside the machine head 2. A telescopic source component 410 is installed inside the fixing component 49. A double needle 411 is installed at the bottom of the telescopic source component 410. A bonding component 401 that fits with the fabric is provided on the mounting frame 42. When the fabric moves directly under the pressure plate 45, the operation of the two sets of cylinders 43, connected by the connecting plate 44, causes the pressure plate 45 to press and fix the fabric at the back pocket of the jeans, thereby improving the sewing stability of the fabric and enhancing the sewing quality of the back pocket of the jeans. Furthermore, by passing the two-color thread through the double needles 411 and with the continuous extension and retraction of the telescopic source 410, different colored threads can be quickly switched, thereby increasing the production rate of the back pocket of the jeans. With the support of the auxiliary needle 48, the sewing quality is also improved.

[0032] In the fabric production process, to fix the fabric of the back pockets of jeans and further improve the processing effect of the device on the jeans pockets, the bonding assembly 401 includes a second cylinder 4011 mounted on a mounting frame 42. A lifting plate 4012 is mounted on the second cylinder 4011, and an electric push cylinder 4013 is mounted on the lifting plate 4012. A bonding plate 4014 adapted to the pressure plate 45 is mounted on the electric push cylinder 4013. The height of the bonding plate 4014 can be adjusted by operating the second cylinder 4011, and the longitudinal position of the bonding plate 4014 can be adjusted by operating the electric push cylinder 4013, thereby improving the fixing effect on the jeans and increasing the efficiency of sewing the jeans pockets.

[0033] Example 2

[0034] Based on Example 1, such as Figures 1-7 As shown, based on the existing technology, the fabric production rate is reduced due to manual pressing of the fabric and the inability to quickly switch between different colored threads. However, in the fabric processing process, if the processed fabric is not quickly removed after processing, it will easily affect the processing of other fabrics, thereby affecting the fabric production efficiency. Therefore, the device is also equipped with a structure for automatically picking up the processed fabric.

[0035] During the fabric production process, the processed fabric can be automatically folded and stored, accelerating the fabric processing speed. The shrinking mechanism 3 includes a pneumatic rod 31 mounted on the frame 1, with a connector 32 rotatably mounted on the pneumatic rod 31. A fixing plate 33 is mounted on the frame 1, and a support sleeve 34 is mounted on the fixing plate 33. A shrinking rod 35 connected to the connector 32 is rotatably mounted on the support sleeve 34. The shrinking rod 35 is adapted to a groove on the front of the frame 1, facilitating the placement of the feeding rod 37 inside the groove, improving the fabric handling efficiency. The shrinking rod 35 is L-shaped, further accelerating the fabric processing efficiency. A support rod 36 is mounted on the frame 1, with the feeding rod 37 mounted on the support rod 36. Through the operation of the pneumatic rod 31, and with the connection of the connector 32, the shrinking rod 35 rotates due to the support of the support sleeve 34, facilitating the placement of the processed jeans onto the feeding rod 37, thus accelerating the jeans production speed.
