[0032] Reference Figure 1 - Figure 3 , the utility model provides an embodiment: a tension-free preshrinkage device for knitted fabrics, including a preshrinkage machine 1, both sides of the preshrinkage machine 1 are fixedly connected with mounting blocks 2, a brush 3 is rotatably connected between the two mounting blocks 2, both sides of the top of the preshrinkage machine 1 are fixedly connected with side plates 4, one of the side plates 4 is fixedly connected with a motor 5 on the outside, a bidirectional threaded rod 6 is fixedly connected with the output end of the motor 5, both sides of the outside of the bidirectional threaded rod 6 are threadedly connected with moving blocks 7, a supporting assembly is arranged at the bottom of the moving block 7, a supporting rod 11 is rotatably connected to the outside of the moving block 7, a sleeve 12 is fixedly connected to the outside of the support rod 11, a telescopic rod 13 is slidably connected to the outside of the sleeve 12, a spring 14 is sleeved on the outer periphery of the telescopic rod 13, one end of the telescopic rod 13 is fixedly connected with a limiting plate 15, a fan box 16 is arranged at the bottom of the brush 3, and plug plates 17 are fixedly connected to the outside of the fan box 16, and fixed assemblies are arranged on both sides of the outside of the preshrinkage machine 1.
[0033] Specifically, the preshrinkage machine 1 is a device for processing knitted fabrics, the mounting block 2 serves to fix the brush 3, the brush 3 serves to remove dust from the knitted fabric, the side plate 4 serves to support and stabilize the motor 5 and the bidirectional threaded rod 6, the motor 5 serves to drive the bidirectional threaded rod 6 to rotate, the moving block 7 serves to drive the support rod 11, the cooperation between the sleeve 12, the telescopic rod 13 and the spring 14 serves to support the limit plate 15, the fan box 16 serves to collect waste by suction, and the plug plate 17 serves to facilitate the installation and fixation of the fan box 16.
[0034] Reference Figure 1 , Figure 3 and Figure 5 The fixing assembly includes a fixing block 18, a paddle rod 19 is slidably connected inside the fixing block 18, a spring 20 is sleeved on one side of the outside of the paddle rod 19, a square plate 21 is fixedly connected to the other side of the outside of the paddle rod 19, a limiting block 22 is fixedly connected to the top of the fixing block 18, a top plate 23 is fixedly connected to the outside of the limiting block 22, a card block 24 is slidably connected inside the limiting block 22, the paddle rod 19 passes through the plug plate 17, the spring 20 is slidably connected to one side of the inside of the fixing block 18, the square plate 21 is slidably connected to the other side of the inside of the fixing block 18, one end of the spring 20 is fixedly connected to the inner wall of the fixing block 18, and the other end of the spring 20 is fixedly connected to the outside of the square plate 21.
[0035] Specifically, the fixed block 18 plays a role in protecting the internal components, the paddle rod 19 plays a role in cooperating with the plug plate 17, thereby achieving the function of installing the fan box 16, the spring 20 plays a resetting role, the block plate 21 plays a role in driving the paddle rod 19, the limit block 22 plays a role in protecting the internal structure, the top plate 23 plays a role in limiting the block 24, and the block 24 plays a role in limiting the block plate 21, thereby achieving the function of limiting the paddle rod 19. When the spring 20 inside the fixed block 18 begins to reset, because the spring 20 is fixedly connected to the block plate 21, the spring 20 drives the block plate 21 to slide inside the fixed block 18, and then drives the paddle rod 19 through the plug plate 17 through the block plate 21, thereby completing the fixed installation.
[0036] Reference Figure 1 , Figure 3 and Figure 4 The support assembly includes a support column 8 and a fixed plate 9. The top of the support column 8 is fixedly connected to the bottom of the moving block 7. Both ends of the fixed plate 9 are fixedly connected between the two side plates 4. A slide groove 10 is opened inside the fixed plate 9. The bottom of the support column 8 is slidably connected inside the slide groove 10. One end of a spring 14 is fixedly connected to the side of the sleeve 12 away from the support rod 11, and the other end of the spring 14 is fixedly connected to the side of the limit plate 15 close to the support rod 11. Both ends of the bidirectional threaded rod 6 are rotatably connected between the two side plates 4, and the external plug plate 17 is slidably connected inside the pre-shrinking machine 1.
[0037] Specifically, the support column 8 slides with the moving block 7 in the slide groove 10 inside the fixed plate 9 to achieve the supporting effect on the moving block 7. The fixed plate 9 facilitates the sliding of the support column 8, and the slide groove 10 facilitates the sliding of the support column 8 inside it. By starting the motor 5, the bidirectional threaded rod 6 is driven to rotate. When the bidirectional threaded rod 6 rotates, it drives the moving block 7 outside it to move. At the same time, the support column 8 at the bottom of the moving block 7 also slides inside the slide groove 10. When the moving block 7 moves, it will drive the support rod 11 to move together until the limiting plate 15 contacts the knitted fabric, thereby achieving the limiting effect on the knitted fabric, so that it remains stable during operation.
[0038] Working principle: When using a tension-free preshrinkage device for knitted fabrics, first adjust the limit assembly according to the width of the knitted fabric, and start the motor 5 to drive the bidirectional threaded rod 6 to rotate. When the bidirectional threaded rod 6 rotates, it drives the moving block 7 outside it to move, and at the same time, the support column 8 at the bottom of the moving block 7 also slides inside the slide groove 10. When the moving block 7 moves, it will drive the support rod 11 to move together until the limit plate 15 contacts the knitted fabric and reaches the limit for the knitted fabric. Then, the knitted fabric is transported to the inside of the preshrinkage machine 1 through the brush 3. When the knitted fabric passes through the brush 3, the brush 3 brushes off the dust and fluff on its surface. The dust and fluff brushed off are sucked into the inside by the suction force generated by the fan box 16. When the machine is not working, the fan box 16 can be removed through the fixing assembly for cleaning. First, pull the paddle rod 19 , the square plate 21 is driven to slide inside the fixed block 18 by the paddle rod 19 and the spring 20 is compressed. At the same time, the block 24 slides to the outside of the paddle rod 19 to limit the displacement of the square plate 21. Because the paddle rod 19 is fixedly connected to the square plate 21, the block 24 also serves to limit the paddle rod 19, so that the paddle rod 19 is separated from the inside of the plug plate 17. Then the fan box 16 is removed for cleaning. After cleaning, the plug plate 17 outside the fan box 16 is reinstalled, and then the block 24 is lifted. At this time, the spring 20 inside the fixed block 18 begins to reset. Because the spring 20 is fixedly connected to the square plate 21, the spring 20 drives the square plate 21 to slide inside the fixed block 18, and then drives the paddle rod 19 through the plug plate 17 through the square plate 21, thereby completing the fixed installation.
[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
