Description

Technical Field

[0001] This utility model relates to the field of spreading machine technology, specifically to a spreading device for an untwisting spreading machine. Background Technology

[0002] The spreading machine is an essential piece of equipment in the dyeing and printing industry for setting processes such as boiling, bleaching, dyeing, dehydration and spreading. The spreading machine turns the rope-like fabrics after dyeing and dehydration of knitted, woven, and warp-weft knitted fabrics into flat fabrics, while the spreading machine uses a spreading device during operation.

[0003] A spreading machine uses a beak to open a cylindrical fabric, suitable for opening knitted fabrics. Currently, most spreading machines use multiple fabric rollers with oppositely rotating threads on them. The fabric is spread by the interaction of the threads. However, relying solely on the fabric rollers to spread the fabric is not ideal for textiles with low thickness and density, such as yarns. This can lead to tangling and other problems after the fabric is spread, resulting in poor overall practicality.

[0004] Therefore, we propose a fabric spreading device for a twist-reversing and spreading machine to solve the above problems. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an embodiment of the present invention provides a fabric spreading device for a twist-reducing and spreading machine, including a support 1, a connecting plate 2 fixedly connected to the middle of one side of the support 1, and a fixing seat 3 fixedly disposed on one end surface of the connecting plate 2.

[0027] A guide roller 4 is rotatably connected to the side wall of the fixed base 3, and a rubber strip 5 is sleeved on the outer surface of the guide roller 4. Four guide rollers 4 are provided, arranged in pairs, with the two pairs of guide rollers 4 symmetrically distributed along the transverse center line of the spreading belt 11. The rubber strip 5 is spirally coiled on the outer ring surface of the guide roller 4. A first motor 6 is fixed to one end of the back of the connecting plate 2, and the output end of the first motor 6 is connected to a first pulley 7. Multiple small teeth are equidistantly distributed along the center point on the outer ring surfaces of the first pulley 7 and the second pulley 9. The first pulley 7 and the second pulley 9 are meshed with the internal tooth belt 8 through the teeth. The outer ring surface of the first pulley 7 is fitted with the internal tooth belt 8, and the inner side of the other end of the internal tooth belt 8 is connected to the second pulley 9. One end of the second pulley 9 is fixedly connected to the rotating roller 10, and the outer ring surface of the rotating roller 10 is fitted with the spreading belt 11. The spreading belt 11 and the front end extension of the connecting plate 2 are inclined, and the inclination angle of the spreading belt 11 is consistent with the inclination of the guide roller 4. The inner side of the other end of the spreading belt 11 is connected to the driven roller 12.

[0028] In use, when the fabric passes through the guide roller 4 under the conveying action of the roller body, the fabric will come into contact with the rubber strip 5 coiled on the outer ring surface of the guide roller 4. Since the guide roller 4 and the fixed base 3 are rotatably connected, the guide roller 4 will rotate under the conveying action of the fabric. The guide roller 4 is inclined, so the rotation of the guide roller 4 facilitates the subsequent use of the rubber strip 5 to perform preliminary unfolding of the fabric. At the same time, the first motor 6 works, causing the first pulley 7 connected to its output end to rotate. At this time, the rotation of the first pulley 7 drives the internal toothed belt 8 meshing with its outer ring surface to follow. The first motor rotates, and then the inner toothed belt 8 rotates, driving the second pulley 9 connected to its other inner side to rotate as well. This facilitates the rotation of the rotating roller 10 by using the rotation of the second pulley 9. At this time, the rotation of the rotating roller 10 drives the spreading belt 11 to move, and the movement of the spreading belt 11 drives the driven roller 12 to rotate, which facilitates the further unfolding of the conveyed fabric. It is worth noting that there are two first motors 6, and the two first motors 6 work independently. The first motors 6 are symmetrically arranged on both sides and their rotation directions are opposite. Therefore, the movement directions of the spreading belts 11 on both sides are also opposite.

[0029] like Figure 1 and Figure 2 As shown, in some embodiments, a first fixed roller 13 is rotatably connected to the bottom inner side of the bracket 1, a second motor 14 is fixedly installed on the top side wall of the bracket 1, and the output end of the second motor 14 is connected to a first feeding roller 15. The other end of the first feeding roller 15 is fixedly connected to a drive gear 16, and a driven gear 17 is meshed on one side of the top end of the drive gear 16. The drive gear 16 is fixedly connected to the first feeding roller 15 through a rod passing through the side wall of the bracket 1. A second feeding roller 18 is fixedly connected to the center point of one end of the driven gear 17, and a second fixed roller 19 is distributed on one side of the second feeding roller 18. The two ends of the second fixed roller 19 are rotatably connected to the bracket 1 through bearing seats.

[0030] In use, the fabric passes through the first fixed roller 13, which assists in conveying the fabric. After being conveyed, the fabric passes through the spreading belt 11 and the guide roller 4. After spreading, the fabric passes through the first feeding roller 15. At this time, the rotation of the first feeding roller 15 drives the drive gear 16 fixedly connected to its other end to rotate. The rotation of the drive gear 16 drives the driven gear 17 meshing with it on one side to rotate as well. This facilitates the subsequent movement of the second feeding roller 18 by the rotation of the driven gear 17. The first feeding roller 15 and the second feeding roller 18 move in opposite directions, which facilitates the subsequent better conveying of the fabric by the second fixed roller 19.

[0031] like Figure 3 and Figure 4 As shown, in some embodiments, the guide roller 4 is rotatably connected to the fixed base 3 via a shaft, and the guide roller 4 and the fixed base 3 are inclinedly distributed.

[0032] When in use, as the fabric passes through the guide roller 4 during the conveying process, the inclined distribution of the guide roller 4 facilitates the subsequent unfolding of the fabric.

[0033] like Figure 3 and Figure 4 As shown, in some embodiments, one end of the rotating roller 10 is fixedly connected to the second pulley 9, and the other end of the rotating roller 10 is rotatably connected to the front end extension of the connecting plate 2 through a bearing seat.

[0034] When in use, when the second pulley 9 rotates, the rotating roller 10 will rotate accordingly. Then, the rotation of the rotating roller 10 will facilitate the movement of the spreading belt 11 fitted on its outer surface.

[0035] like Figure 2 As shown, in some embodiments, the outer ring surface of the driving gear 16 has teeth evenly distributed along the center point, and the driving gear 16 forms a meshing connection with the driven gear 17 through the teeth.

[0036] In use, since the driving gear 16 and the driven gear 17 are meshed, the rotation of the driving gear 16 can easily enable the subsequent rotation of the driven gear 17.

[0037] In summary, during use, the fabric passes through the spreading guide roller 4 under the rotation of the first fixed roller 13. The fabric then contacts the rubber strip 5 coiled on the outer ring of the guide roller 4. Since the guide roller 4 and the fixed base 3 form a rotatable connection, the guide roller 4 rotates under the conveying action of the fabric. Because the guide roller 4 is inclined, the rotation of the guide roller 4 facilitates the subsequent initial spreading of the fabric using the rubber strip 5. Simultaneously, the first motor 6 operates, causing the first pulley 7 connected to its output end to rotate. This rotation of the first pulley 7 drives the inner toothed belt 8, which is meshed with its outer ring, to rotate. The rotation of the inner toothed belt 8 then drives the second pulley 9, connected to its other inner side, to rotate as well. This facilitates the subsequent rotation of the rotating roller 10, which in turn drives the spreading belt 11 to move. The movement of the spreading belt 11 then drives the driven roller 12 to rotate, facilitating further spreading of the conveyed fabric. After being spread out, the fabric passes through the first feeding roller 15. The rotation of the first feeding roller 15 drives the drive gear 16 to rotate. The rotation of the drive gear 16 drives the driven gear 17 to move the second feeding roller 18, which facilitates the subsequent transport and processing of the fabric by the second fixed roller 19.

[0038] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
