Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of industrial sewing machines, in particular to a feeding device of an industrial sewing machine. Background Art
[0002] The feeding device of a sewing machine is a key component of the sewing machine. It is responsible for driving the fabric to feed at the set speed and direction to ensure the smooth progress of the sewing process.
[0003] During use of the feeding device of the existing industrial sewing machine, during the process of sewing the cloth, the feed teeth continuously push the cloth to one side. During the movement of the cloth, the operator is required to have professional skills and rich experience to control the direction of the cloth movement and complete the predetermined sewing trajectory. For novice or inexperienced operators, they may not be able to master the rhythm and strength of the cloth movement, resulting in the cloth being offset, twisted or misaligned during the movement, thereby reducing the quality of production. In addition, during the sewing process, the cloth may be squeezed by the presser foot and the feed teeth, which may cause wrinkles. Usually, the feeding device does not have a mechanism to eliminate cloth wrinkles, and this problem cannot be solved. Cloth wrinkles will directly affect the flatness and aesthetics of the sewing, thereby reducing the overall quality of the product. Utility Model Content

[0022] Please refer to Figures 1-4As shown in the figure, a feeding device for an industrial sewing machine includes a sewing machine body 1. A workbench 2 is provided at the bottom of the sewing machine body 1, and a housing 3 is provided on one side of the sewing machine body 1. A water tank 4 is provided below the workbench 2, and a feeding tooth 5 is provided on the outer side of the sewing machine body 1. By providing the feeding tooth 5, the feeding tooth 5 is a part of the feeding device of the sewing machine and is responsible for driving the fabric to be fed at a set speed and direction. During the sewing process, the feeding tooth 5 is in direct contact with the fabric, and its rotation drives the fabric to move forward, ensuring that the sewing thread can be sewn along a predetermined trajectory. This is the prior art and will not be elaborated here. It further includes: a driving component 6 provided inside the housing 3, a transmission component 7 provided on the outer side of the driving component 6, and a moving plate 8 provided on the outer side of the transmission component 7. By providing the moving plate 8, while the bidirectional screw 72 rotates following the worm gear 71, it can drive the moving plate 8 threadedly connected to its outer side to perform lifting adjustment; a guiding component 9 for guiding the moving path is provided on one side of the moving plate 8, a buffer component 10 is provided inside the moving plate 8, and a pressing wheel 15 for limiting the fabric is provided at one end of the buffer component 10. By providing the pressing wheel 15, a pressing wheel 15 is also provided on one side of the housing 3. When the upper and lower groups of pressing wheels 15 are attached to the outer side of the fabric, it can guide the direction of the fabric during the sewing process of the fabric, preventing the fabric from shifting and improving the production quality of the fabric; a conveying component 11 is provided on the outer side of the water tank 4, a manufacturing component 12 is provided inside the water tank 4, a fixing seat 13 is provided on the outer side of the conveying component 11, and two heating rollers 14 for removing wrinkles from the fabric are rotatably connected inside the fixing seat 13. By providing the heating rollers 14, the surface of the heating rollers 14 can be heated to a certain temperature. After the fabric is sewn, in cooperation with the hot steam delivered through the steam holes 112, the wrinkles that appear on the fabric during the sewing process can be eliminated.
[0023] The driving component 6 includes a runner 61 arranged on one side of the housing 3. By arranging the runner 61, when it rotates, it drives the worm 62 to rotate. By arranging the worm 62, when it rotates, it drives the meshing-connected worm wheel 71 outside it to rotate; one side of the runner 61 is fixedly connected with the worm 62; the transmission component 7 includes a worm wheel 71 meshing on the outside of the worm 62, and a bidirectional screw 72 is arranged inside the worm wheel 71. By arranging the bidirectional screw 72, when it rotates, it drives the moving plate 8 connected by threads outside it to perform lifting adjustment; the guiding component 9 includes two guiding blocks 91 fixed on one side of the moving plate 8, and the outside of the guiding block 91 is slidably connected with a guiding groove 92. By arranging the guiding component 9, when the guiding block 91 moves following the moving plate 8, it slides along the inside of the guiding groove 92, and the guiding groove 92 provides guidance for the moving path of the moving plate 8, improving the moving stability of the moving plate 8; the buffering component 10 includes a sliding rod 101 sliding inside the moving plate 8. By arranging the sliding rod 101, it can slide inside the moving plate 8; a spring 102 is sleeved on the outside of the sliding rod 101. By arranging the spring 102, the elastic force generated by it can reduce the risk of the fabric being damaged due to excessive clamping in the limited state.
[0024] The conveying component 11 includes a conveying pipe 111 arranged on the outside of the water tank 4. By arranging the conveying pipe 111, it facilitates the steam to be conveyed through it to the steam holes 112. By arranging the steam holes 112, when the fabric passes above it, the steam sprayed out by it can penetrate the fibers of the fabric, soften the fabric and increase the fluffiness, eliminating wrinkles and unevenness; four steam holes 112 are horizontally arranged on the outside of the conveying pipe 111, and a return pipe 113 is communicated with the outside of the conveying pipe 111. By arranging the return pipe 113, the outlet of the steam hole 112 is designed as an inclined surface, and water droplets are easily formed at the steam hole 112. The water droplets can flow back into the conveying pipe 111 under the influence of their own gravity, and then flow downward and flow into the water tank 4 through the return pipe 113, realizing the effective conservation of water resources and ensuring the recycling of water; the manufacturing component 12 includes an atomizer 121 arranged inside the water tank 4. By arranging the atomizer 121, it facilitates the conversion of water into water mist; a blower 122 is arranged above the atomizer 121. By arranging the blower 122, it facilitates the rapid conveying of the water mist to the top of the conveying pipe 111; a heating wire 123 is arranged at the air outlet end of the blower 122. By arranging the heating wire 123, the water mist blown out by the blower 122 is heated by it to form water vapor.
[0025] Working principle: When in use and it is necessary to limit the fabric, rotate the runner 61, drive the worm gear 71 to rotate through the worm 62. While the bidirectional screw 72 rotates accordingly, the moving plate 8 threadedly connected to its outer side moves downward along the guiding groove 92. Subsequently, the pressing wheel 15 fits on the surface of the fabric. When the feeding teeth 5 drive the fabric to move, the fabric slides along the inner sides of the upper and lower groups of pressing wheels 15, so that the fabric will not shift during the sewing process, improving the production quality. Subsequently, the sewn fabric moves towards the heating roller 14. The atomizer 121 is started to convert the water in the water tank 4 into water mist. The water mist blown out by the blower 122 is heated by the heating wire 123 to form water vapor with a certain temperature and is quickly blown by the wind to the top of the conveying pipe 111 and sprayed onto the fabric surface through the steam holes 112 on its outer side. The steam can penetrate the fibers of the fabric to soften the fabric. At the same time, when the surface of the heating roller 14 is heated to a certain temperature, it irons the fabric passing through its outer side to eliminate the wrinkles.
