The bottoms of the first edge pressing mechanism and the second edge pressing mechanism are both in rolling fit connection with a belt. The structures and shapes of the first edge pressing mechanism and the second edge pressing mechanism are the same.

[0009] Further, the first edge pressing mechanism includes a first double-acting cylinder; a positioning ring is fixedly connected to the center of the central axis of the outer wall of the first double-acting cylinder. A positioning column is fixedly connected to the top of the positioning ring, and a second double-acting cylinder is fixedly connected to the top end of the positioning column. The output ends on both sides of the first double-acting cylinder are drivingly connected to limiting parts, and the output ends on both sides of the second double-acting cylinder are drivingly connected to linkage parts, and the bottom of the linkage part is rotatably connected to the top of the limiting part.

[0010] Further, the limiting part includes an outer cylinder; one end of the outer cylinder is of an open structure, and the other end of the outer cylinder is of a closed structure. A plurality of heat dissipation holes are formed on the outer wall of the outer cylinder on the side far away from the opening. An inner ring is fixedly connected to the inner wall of the outer cylinder on the side close to the closed end.

[0011] Further, the inner wall of the outer cylinder on the side close to the closed end is drivingly connected to the output end of the first double-acting cylinder. A docking ring is fixedly connected to the end of the outer cylinder close to the opening. An adsorption magnetic ring is fixedly connected to one end of the docking ring. An assembly cavity is arranged between the inner wall of the adsorption magnetic ring and the outer wall of the inner ring.

[0012] Further, a limiting ring is movably clamped in the assembly cavity, and a sealing ring is fixedly connected to one end of the limiting ring. A plurality of groups of micro fans are embedded on the outer wall of the sealing ring on the side far from the limiting ring. A plurality of groups of mounting holes are formed in one side wall of the limiting ring. One ends of the plurality of groups of mounting holes communicate with the micro fans, and the other ends of the plurality of groups of mounting holes communicate with the assembly cavity.

[0013] Further, the linkage part includes a linkage ring; the inner wall of the linkage ring is slidably and fittingly connected to the outer cylinder and the docking ring, and the inner wall of the linkage ring is also adsorbed and connected to the adsorption magnetic ring. A plush layer is arranged on the outer wall of the linkage ring.

[0015] The beneficial effects of the present invention are as follows:

[0016] 1. The top of the fabric conveying assembly is used to convey the fabric. During the conveying process, the first fabric fixing assembly and the second fabric fixing assembly move downward, and first fix the two sides of the fabric and synchronously press the fabric when approaching the fabric conveying assembly. After the fabric is pressed and enters the electric sewing machine, the electric sewing machine is driven by the electric slide to reciprocate, so as to sew and process the fabric with both sides fixed, and can reasonably fix both sides of the fabric before and after sewing.

[0017] 2. When the output end of the first double-shaft cylinder pushes the limiting parts on both sides to move horizontally, the two docking rings can move towards each other, so that the fabric clamped between the two docking rings and the belt is horizontally stretched. While the driven wheel moves horizontally on the spline rod, it compresses the spring to assist in completing the horizontal stretching action of the fabric, so that the fabric during sewing is in a continuously taut state.

[0018] 3. Pull the linkage parts on both sides through the output end of the second double-shaft cylinder, so that the linkage rings inside move to the adsorption magnetic rings and are magnetically adsorbed and connected to each other. Then, use the plush layer on the surface of the linkage ring to elastically contact natural fiber fabrics such as silk materials, avoiding problems caused by the smooth and soft texture that is easy to snag during the sewing process. The felt roller can always contact the plush layer on the surface of the linkage ring to clean the fabric fibers on the surface of the plush layer.

[0019] 4. Push the linkage parts on both sides through the output end of the second double-shaft cylinder, so that the linkage rings inside block the heat discharge holes. Then, when the micro-fan continues to work and the air flow enters the installation holes, use the continuous operation of the electric heating wire in the installation holes to raise the temperature of the air flow, and use the formed high-temperature air flow to continuously heat the inner wall of the outer cylinder, so that the heated outer cylinder meets the requirements for artificial fiber / blended fabrics such as rayon, and needs to be ironed at a low temperature before sewing.

[0020] Other features and advantages of the present invention will be described in the following specification, and partly will be obvious from the specification, or will be understood by implementing the present invention.

[0040] The limiting part 435 includes an outer cylinder 4351; Exemplarily, as Figure 6 and Figure 7 shown.

[0041] One end of the outer cylinder 4351 is an open structure, and the other end of the outer cylinder 4351 is a closed structure. A plurality of groups of heat dissipation holes 4352 are formed on the outer wall of the outer cylinder 4351 on the side far from the opening. An inner ring 4353 is fixedly connected to the inner wall of the outer cylinder 4351 on the side close to the closed end. The output end of the first double-axis cylinder 431 is in transmission connection with the inner wall of the outer cylinder 4351 on the side close to the closed end. A docking ring 4354 is fixedly connected to the end of the outer cylinder 4351 close to the opening. An adsorption magnetic ring 4355 is fixedly connected to one end of the docking ring 4354. An assembly cavity is provided between the inner wall of the adsorption magnetic ring 4355 and the outer wall of the inner ring 4353. A limiting ring 4358 is movably clamped in the assembly cavity. One end of the limiting ring 4358 is fixedly connected with a sealing ring 4356. A plurality of groups of micro fans 4357 are embedded on the side of the outer wall of the sealing ring 4356 far from the limiting ring 4358. A plurality of groups of mounting holes 4359 are formed on one side wall of the limiting ring 4358. One end of the plurality of groups of mounting holes 4359 is communicated with the micro fans 4357, and the other end of the plurality of groups of mounting holes 4359 is communicated with the assembly cavity. Electric heating wires are arranged on the inner walls of the plurality of groups of mounting holes 4359.

[0042] The linkage part 436 includes a linkage ring 4361; Exemplarily, as Figure 8 shown.

[0043] The inner wall of the linkage ring 4361 is slidably and fittingly connected to the outer cylinder 4351 and the docking ring 4354, and the inner wall of the linkage ring 4361 is also adsorbed to the adsorption magnetic ring 4355. A plush layer is arranged on the outer wall of the linkage ring 4361. Two linkage blocks 4362 are movably abutted against both sides of the top of the linkage ring 4361. Mounting arms 4364 are fixedly connected to the tops of the two linkage blocks 4362. A positioning hollow column 4365 is horizontally penetrated and connected between the two mounting arms 4364. Internal threaded holes 4366 are formed at both ends of the positioning hollow column 4365. Bolts are threadedly connected to the internal threaded holes 4366. The inner wall of the positioning hollow column 4365 is movably and fittingly connected to the output end of the second double-axis cylinder 434. One end of the bolt is fixedly connected to the output end of the second double-axis cylinder 434. A felt roller 4363 is sleeved on the positioning hollow column 4365, and the bottom of the felt roller 4363 is in contact with the plush layer on the surface of the linkage ring 4361.

[0044] Specifically, the output end of the electric push rod 17 drives the linkage rod 42 to move downward, causing the docking rings 4354 inside the two side limiting parts 435 to fall synchronously and approach the belt 16, forming a function of fixing and clamping the two sides of the fabric, so as to fix the double-layer fabric between the belt 16 and the docking ring 4354;

[0045] During the process that the output end of the first double-axis cylinder 431 pushes the two side limiting parts 435 to move horizontally, the two groups of docking rings 4354 can move towards each other, so as to horizontally stretch the fabric clamped between the two groups of docking rings 4354 and the belt 16. At the same time, the driven wheel 15 squeezes the spring while the spline rod 13 moves horizontally, which is used to assist in completing the horizontal stretching action of the fabric, so that the fabric during sewing is in a continuously taut state;

[0046] The output end of the second double-axis cylinder 434 pulls the two side linkage parts 436, so that the linkage rings 4361 inside them move to the adsorption magnetic rings 4355 and are magnetically adsorbed and connected to each other. Then, the plush layer on the surface of the linkage ring 4361 makes elastic contact with natural fiber fabrics such as silk materials, avoiding the problems caused by the smooth, soft and easy-to-hook properties of the material during sewing. And the felt roller 4363 can always contact the plush layer on the surface of the linkage ring 4361 to clean the fabric fibers on the surface of the plush layer;

[0047] The output end of the second double-axis cylinder 434 pushes the two side linkage parts 436, so that the linkage rings 4361 inside them block the heat dissipation holes 4352. Then, when the micro fan 4357 works continuously and the air flow enters the installation hole 4359, the electric heating wire in the installation hole 4359 works continuously to raise the temperature of the air flow, which is used to form a high-temperature air flow to continuously heat the inner wall of the outer cylinder 4351, so that the heated outer cylinder 4351 meets the requirement of low-temperature ironing for artificial fiber / blended fabrics such as rayon before sewing.

[0048] The working principle of a fabric double-side fixing type sewing device proposed by the embodiment of the present invention is as follows:

[0049] By using the output end of the electric push rod 17 to drive the linkage rod 42 to move downward, the docking rings 4354 inside the two side limiting parts 435 fall synchronously and approach the belt 16, forming a function of fixing and clamping the two sides of the fabric, so as to fix the double-layer fabric between the belt 16 and the docking ring 4354;

[0050] During the process of pushing the limiting parts 435 on both sides to move horizontally through the output end of the first double-axis cylinder 431, the two sets of docking rings 4354 can move towards each other, horizontally stretching the fabric clamped between the two sets of docking rings 4354 and the belt 16. At the same time, the driven wheel 15 squeezes the spring while the spline rod 13 moves horizontally, assisting in completing the horizontal stretching action of the fabric, so that the fabric during the sewing process is in a continuously taut state;

[0051] By pulling the linkage parts 436 on both sides through the output end of the second double-axis cylinder 434, when the linkage rings 4361 inside them move to the adsorption magnetic rings 4355 and are magnetically adsorbed and connected to each other, the plush layer on the surface of the linkage ring 4361 makes elastic contact with natural fiber fabrics such as silk materials, avoiding problems caused by the smooth, soft and easy-to-hook-wire nature of the material during sewing. The felt roller 4363 can always be in contact with the plush layer on the surface of the linkage ring 4361 to clean the fabric fibers on the surface of the plush layer;

[0052] By pushing the linkage parts 436 on both sides through the output end of the second double-axis cylinder 434, after the linkage rings 4361 inside them block the heat dissipation holes 4352, and then using the continuous operation of the micro fan 4357, when the air flow enters the installation hole 4359, the continuous operation of the electric heating wire in the installation hole 4359 raises the temperature of the air flow, which is used to continuously heat the inner wall of the outer cylinder 4351 with the formed high-temperature air flow, so that the heated outer cylinder 4351 meets the requirement for artificial fiber / blended fabrics with rayon, and needs to be pre-sewn with low-temperature ironing treatment.

[0053] Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
