These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0021] The following is a further description of the embodiments of the present invention in conjunction with the accompanying drawings:

[0022] Reference Figure 1 and Figure 2 As shown, a sewing machine is a machine that uses one or more sewing threads to form one or more stitches on the sewing material to interweave or sew one or more layers of sewing material. In the working process of the existing sewing machine, the fabric needs to be continuously transported, and the machine head needs to stop during the transportation process. However, the existing stoppage mostly needs to be controlled by the operator, resulting in reduced overall processing efficiency and prone to errors in the sewing process. In order to solve such problems, a zigzag double-needle sewing machine is proposed, including a sewing machine frame 1, the sewing machine frame 1 is provided with a mounting plate 12 on the upper side, a through slot 211 for passing fabric is formed between the mounting plate 12 and the sewing machine frame 1, a pressing member 2 is provided in the through slot 211 for sliding up and down, the pressing member 2 comprises a pressing arc plate 21 which slides vertically up and down along the through slot 211, both sides of the pressing arc plate 21 are arranged in an upwardly curved shape, and a clamping groove 213 is provided in both sides of the pressing arc plate 21, a guide rod 223 is slidably provided in the clamping groove 213, one end of the guide rod 223 extends outward to the pressing arc plate 2 1, and a buffer plate 221 is provided on one end of the guide slide rod 223 below the pressing arc plate 21, and a limit plate 224 is provided on the other end of the guide slide rod 223 relative to the buffer plate 221 for sliding and limiting the guide slide rod 223, and a reset member 22 for resetting the buffer plate 221 is provided between the buffer plate 221 and the slot 213, and a driving member 3 for driving the pressing arc plate 21 to slide up and down is provided on the upper side of the pressing arc plate 21; the arrangement of the sewing machine frame 1 and the mounting plate 12 can achieve the effect of making the cloth The purpose of orderly transmission is achieved in the through groove 211, and the setting of the pressing arc plate 21 in the pressing member 2 can achieve the purpose of real-time pressing or contact pressing of the cloth in the through groove 211, and can cooperate with the machine head to perform the sewing process in real time. The setting of the buffer plate 221 can also achieve the purpose of moving the raised parts of some cloth downwards, and can ensure that the cloth is in a relatively flat state during processing. The setting of the driving member 3 can achieve the effect of making the above-mentioned pressing member 2 present a reciprocating pressing effect on the cloth, which greatly improves the processing efficiency.

[0023] It should be noted that the pause of the fabric during the sewing process mentioned above specifically refers to that when the sewing machine head is processing a certain area of ​​the fabric, the fabric is in a non-transmitted state. When the sewing machine head has completed processing of this area, the operator is required to pull the fabric to realize a transmission process, and the process of pulling the fabric is the process of the sewing machine pause. In this embodiment, the purpose of orderly pressing or contact pressing of the fabric can be achieved by setting the pressing arc plate 21 in the pressing member 2.

[0024] Moreover, the entire arc-pressing plate 21 presents an upward arc surface in order to avoid damage to the fabric by the two ends of the arc-pressing plate 21. The above arrangement can achieve the purpose of protecting the fabric. A protective coating 212 is also provided on the top of the arc-pressing plate 21 to prevent burrs on the fabric.

[0025] Furthermore, the buffer plate 221 can not only provide buffering protection for the fabric, but also ensure the purpose of pressing down the protruding part of the fabric. After the fabric passes through, in order to ensure that the buffer plate 221 can be reset, in this embodiment, the reset member 22 includes a reset spring 222 arranged between the buffer plate 221 and the slot 213, one end of the reset spring 222 is arranged on a side surface of the buffer plate 221 close to the slot 213, and the other end is arranged on a side wall of the slot 213 close to the buffer plate 221. The reset spring 222 can be arranged to drive the buffer plate 221 to gradually reset after the buffer plate 221 is separated from the contact with the fabric, thereby ensuring the continuous operation of the buffer plate 221.

[0026] It should also be noted that in order to prevent the above-mentioned buffer plate 221 from causing damage to the fabric, in this embodiment, a protective pad 2211 is provided on the bottom surface of the buffer plate 221 for protecting the raised part of the fabric; the provision of the protective pad 2211 can achieve the purpose of making the buffer plate 221 have a better protective effect.

[0027] Furthermore, the specific structure of the above-mentioned driving member 3 is as follows: the driving member 3 includes a telescopic cylinder 31 arranged in the mounting plate 12, and a pushing base plate 32 is provided at the output end of the telescopic cylinder 31, and a plurality of mounting rods 33 are connected between the pushing base plate 32 and the top of the pressing arc plate 21; through the setting of the telescopic cylinder 31, the purpose of making the pushing base plate 32 slide up and down in an orderly manner when the telescopic cylinder 31 is running can be achieved, thereby driving the mounting rod 33 and the pressing arc plate 21 to slide up and down synchronously, and the whole up and down sliding process is the process of the fabric being processed or transmitted.

[0028] It should be noted that in order to ensure that the above-mentioned pushing base plate 32 and the pressure arc plate 21 can slide up and down in an orderly manner, in this embodiment, guide rails 331 are also provided on both sides of the mounting plate 12 for enabling the pushing base plate 32 to slide up and down in an orderly manner; the arrangement of the guide rails 331 can ensure the orderliness of the up and down sliding of the pushing base plate 32 and the pressure arc plate 21.

[0029] It is worth mentioning that in order to ensure that the entire sewing machine frame 1 can be stably set on the ground, in this embodiment, the bottom of the sewing machine frame 1 is provided with supporting feet 11 for supporting the sewing machine frame 1; the setting of the supporting feet 11 can achieve the sewing machine frame 1 being stably set on the ground.

[0030] It should be emphasized that the embodiments described in the present invention are illustrative rather than restrictive. Therefore, the present invention is not limited to the embodiments described in the specific implementation manner. Any other implementation manners derived by those skilled in the art based on the technical solution of the present invention also fall within the scope of protection of the present invention.
