Description
Technical Field
[0001] The utility model relates to the technical field of a width opening machine, in particular to a twist-releasing and cloth-loosening mechanism of a width opening machine. Background Art
[0002] When printing and dyeing, fabrics often need to be wet processed and dehydrated. After passing through the dehydration treatment port, the fabric is easily twisted into a rope-like object. When it is processed in the next process, it needs to go through a detwisting and opening process to unfold the fabric into a sheet of cloth. To unfold the rope-like fabric, an opening machine is often used.
[0003] The detwisting mechanism is generally used in the opening machine to detwist the cloth. After a series of processing, the cloth is basically in an uncertain state, such as curled, twisted or wrinkled. At this time, the cloth needs to be detwisted to unfold it.
[0004] When loosening cloth, most existing opening machines put the cloth on the cloth loosening roller and rotate the cloth loosening roller to untwist the cloth. However, the cloth will slide and deviate during the rotation, causing the cloth to move toward the end of the roller, making it inconvenient to untwist the cloth, and the untwisting effect is poor, and the untwisting cannot be fully untwisted, thereby reducing the quality of untwisting and loosening the cloth.

[0021] It should be noted that the opening machine belongs to the existing technology in this field. The main innovation of this article is not in the opening machine. Its positioning is only included, so it will not be described in detail.
[0022] In this embodiment, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a first motor 51 is fixed to the bottom of the fixed plate 4, and a rotating shaft 52 is fixedly connected to the output end of the first motor 51. The rotating shaft 52 is rotatably connected to the fixed plate 4. A turntable 53 is fixedly sleeved on the outside of the rotating shaft 52, and a protruding rod 54 is fixed on the surface of the turntable 53. A support rod 56 is rotatably embedded in the end of the crank 5, and a support plate 57 is fixed to the bottom of the support rod 56, and the support plate 57 is fixedly connected to the bracket 3.
[0023] In this embodiment, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an annular groove 55 is provided on the surface of the crank 5, and the protruding rod 54 is placed in the annular groove 55 to slide horizontally.
[0024] It should be noted that the annular groove 55 is provided to facilitate the sliding of the protruding rod 54 inside the annular groove 55 , and the crank 5 swings back and forth along with the sliding of the protruding rod 54 .
[0025] In this embodiment, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a second motor 91 is fixed to the surface of the connecting frame 7, and a rotating rod 92 is fixedly connected to the output end of the second motor 91. A worm 94 is fixedly sleeved on the outside of the rotating rod 92, and a worm wheel 95 is meshed at the end of the worm 94. A rotating rod 96 is fixed in the middle of the worm wheel 95, and a gear 97 is fixedly sleeved on the bottom outside of the rotating rod 96, and a toothed plate 98 is meshed at the end of the gear 97.
[0026] In this embodiment, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, support blocks 93 are rotatably sleeved at both ends of the rotating rod 92, the support blocks 93 are fixedly connected to the connecting frame 7, and the rotating rod 96 is placed in the connecting frame 7 for rotational movement.
[0027] In this embodiment, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a protrusion is installed on the side wall of the tooth plate 98, the second unwinding wheel 9 is fixedly connected to the tooth plate 98 through the protrusion, and a sliding groove 71 is opened on the side wall of the connecting frame 7 to facilitate the horizontal sliding of the protrusion.
[0028] It should be noted that a protrusion is installed at the end of the tooth plate 98, and the tooth plate 98 is connected to the second unwinding wheel 9 through the protrusion. When the tooth plate 98 slides horizontally, the second unwinding wheel 9 installed at the end through the protrusion can slide with the tooth plate 98, and then the distance between the second unwinding wheel 9 and the first unwinding wheel 8 can be adjusted, so that it can clamp and limit cloth of different thicknesses.
[0029] It should be noted that the specific models and specifications of the first motor 51 and the second motor 91 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it is not repeated here.
[0030] The use method and advantages of the utility model: When the untwisting and loosening cloth mechanism of the width-opening machine is working, the working process is as follows:
[0031] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, when the cloth loosening mechanism is used to untwist and loosen the cloth, the spacing between the first untwisting wheel 8 and the second untwisting wheel 9 is first adjusted according to the thickness of the twisted cloth, and the second motor 91 is started to drive the rotating rod 92 to rotate in the supporting block 93. When the rotating rod 92 rotates, the worm 94 outside it rotates immediately and meshes with the worm wheel 95. The worm wheel 95 is rotated by force and drives the rotating rod 96 in the middle to rotate. When the rotating rod 96 rotates, the gear 97 placed inside the connecting frame 7 rotates immediately, and meshes with the tooth plate 98 during the rotation. The tooth plate 98 is forced to drive the protrusion to slide horizontally in the slide groove 71 on the side wall of the connecting frame 7. The second untwisting wheel 9 connected to the end of the protrusion slides immediately and then adjusts the spacing of the cloth, so that the cloth is limited to avoid slipping during the process of loosening the cloth, so that the cloth is always kept between the first untwisting wheel 8 and the second untwisting wheel 9 during the rotation, so that the cloth will not slide or deviate when the cloth is loosened, thereby improving the untwisting effect.
[0032] Then, the first motor 51 is started to drive the rotating shaft 52 to drive the turntable 53 to rotate. When the turntable 53 rotates, the protruding rod 54 on its surface slides in the annular groove 55 of the crank 5, so that the crank 5 is forced to rotate around the support rod 56. At the same time, with the continuous rotation of the rotating wheel, the crank 5 is forced to swing back and forth, thereby driving the connecting frame 7 installed at the end through the connecting rod 6 to swing back and forth, so that the cloth clamped between the first unwinding wheel 8 and the second unwinding wheel 9 at the end of the connecting frame 7 swings back and forth back and forth, so that the cloth is pulled back and forth one by one and then untwisted, so that the cloth is fully untwisted, and the quality of cloth loosening and untwisting is improved.
[0033] The above shows and describes the basic principle, main features and advantages of the utility model. Technical staff in this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, which fall within the scope of the utility model to be protected.
