Abstract
Description
Technical Field
[0001] The utility model relates to a rolling mill for fabric production, in particular to a rolling mill for ribbon production. Background Art
[0002] After the weaving process, the ribbon generally needs to be dyed to make the ribbon have rich colors and patterns. In the dyeing process, the ribbon fabric needs to be pre-treated to remove impurities and residues. Then, the ribbon is dyed with dye. Dyeing can be done by soaking, spraying or printing. When soaking dyeing is used, it is generally necessary to use a padder for pressing. In the fabric dyeing and finishing process, the padder is used to improve the flatness of the fabric, adjust the density of the fabric, and stabilize the size of the fabric. The padder can not only remove excess water from the fabric, but also improve the uniformity of the rolling liquid and improve the dyeing effect.
[0003] However, the webbing is sensitive to pressure control during the rolling process. When the pressure is too high, the remaining amount of liquid in the webbing is small, the pigment content is too low, and the color after drying is too light; when the pressure is too low, the remaining amount of liquid in the webbing is too much, the pigment content is too high, and the color after drying is too dark, which will also increase the subsequent drying time. Since the thickness of each batch of webbing may be slightly different, and the preset spacing between the loading roller and the bearing roller on the rolling machine is generally fixed, this will cause different batches of webbings with different thicknesses to be subjected to different rolling forces during the rolling process, resulting in inconsistent dyeing and finishing effects. Summary of the invention
[0004] The utility model provides a rolling machine for ribbon production, which solves the problem in the prior art that ribbons of different batches and thicknesses have different dyeing and finishing effects after rolling.
[0005] The above-mentioned technical problems of the utility model are mainly solved by the following technical solutions: a rolling machine for ribbon production, comprising a loading roller and a load-bearing roller arranged to rotate horizontally, characterized in that it also includes a turning frame rotatably connected at one end, a first guide roller arranged to rotate horizontally, a second guide roller arranged to rotate horizontally and a fixed limit rod, the other end of the turning frame is connected to a loading cylinder, the loading roller is rotatably connected to the turning frame, a plurality of rubber rings distributed at equal intervals are sleeved on the loading roller, and pre-tightening positioning sleeves screwed to the loading roller are arranged on both sides of each rubber ring, and the pre-tightening positioning sleeve is provided with a rotating portion that forms a rotational fit with the outer wall of the loading roller and an abutting portion that abuts against the rubber ring.
[0006] The utility model controls the flipping state of the flip frame by a loading cylinder. When the utility model needs to perform rolling, the loading cylinder pushes the flip frame to rotate until it abuts against the limit rod, and makes the rubber ring on the loading roller abut against the load-bearing roller. Since the position of the limit rod is fixed, the abutment axis distance between the loading roller and the load-bearing roller is fixed. After the rubber ring contacts the load-bearing roller, a certain deformation will occur. The greater the deformation, the greater the contact area between the two, the greater the rolling force, and the more obvious the rolling effect. After the rubber ring is worn, its outer diameter will be slightly reduced, so the rolling force will be reduced, and the thickness change of the webbing will also affect the actual rolling force. The utility model can change the spacing between the two abutting parts by rotating the two sides of the rubber ring to pre-tighten the positioning sleeve, so as to achieve fine adjustment of the outer diameter of the rubber ring. Specifically, when the spacing is reduced, the rubber ring is squeezed, so the outer diameter of the rubber ring tends to increase; when the spacing is increased, the rubber ring tends to rebound to its original state, so the outer diameter of the rubber ring tends to decrease.
[0007] Furthermore, the two guide rollers each include a core shaft, a guide wheel sleeved on the core shaft, a positioning ring and a locking ring. The core shaft is provided with an anti-rotation rib. The number and spacing of the guide wheels correspond to the rubber rings one by one. An annular groove is provided on the outer wall of the guide wheel. The positioning ring is located on both sides of the guide wheel. The locking ring is screwed to both ends of the core shaft and abuts against the positioning ring. The width of the rubber ring is slightly larger than the width of the webbing. The annular groove on the guide wheel is used to limit the position of the webbing to ensure that the webbing is facing the rubber ring when flowing through the load-bearing roller. At the same time, the utility model can adapt to webbings of different widths by replacing rubber rings of different sizes and guide wheels with annular grooves of different sizes, so that the utility model has good versatility.
[0008] Therefore, compared with the prior art, the utility model has the following characteristics: 1. The utility model pre-tightens the positioning sleeves on both sides of the rotating rubber ring to change the distance between the two abutting parts, thereby achieving fine-tuning of the outer diameter of the rubber ring. In this way, before each pressing, the technician can compare the color of each ribbon after pressing, and then fine-tune the pressing force to achieve uniform dyeing and finishing effects for all ribbons.

[0016] Example 1: See Figure 1 , Figure 2 and Figure 3 A rolling mill for webbing production, comprising a loading roller 10 arranged to rotate horizontally and a rigid bearing roller 20 arranged to rotate horizontally, and also comprising a turning frame 30 rotatably connected at one end, a first guide roller 40 arranged to rotate horizontally, a second guide roller 50 arranged to rotate horizontally and a fixed limit rod 60, the webbing flows through the first guide roller, the bearing roller and the second guide roller in sequence, and the path is Ω-shaped, the other end of the turning frame is connected to a loading cylinder 70, the loading roller is rotatably connected to the turning frame, and four rubber rings 80 distributed at equal intervals are sleeved on the loading roller, and pre-tightening positioning sleeves 90 screwed to the loading roller are provided on both sides of each rubber ring, and the pre-tightening positioning sleeve is provided with a screw-on portion 91 screwed to the outer wall of the loading roller and an abutting portion 92 abutting against the rubber ring (see Figure 4 ), the outer diameter of the abutment part is larger than the outer diameter of the rotation part to increase the contact area with the rubber ring. The bearing roller is a power roller and needs to be connected to the motor transmission, and the loading roller is a non-powered driven roller.
[0017] See Figure 5 , the two guide rollers each include a core shaft 1, four guide wheels 2 sleeved on the core shaft, five positioning rings 3 and two locking rings 4, the core shaft is provided with an anti-rotation rib 11, the number and spacing of the guide wheels correspond to the rubber rings one by one, an annular groove 21 is provided on the outer wall of the guide wheel, the positioning rings are located on both sides of the guide wheel, and the locking rings are screwed to the two ends of the core shaft and abut against the positioning rings. The width of the rubber ring is slightly larger than the width of the webbing, and the annular groove on the guide wheel is used to limit the position of the webbing to ensure that the webbing is facing the rubber ring when flowing through the load-bearing roller. At the same time, this embodiment can adapt to webbings of different widths by replacing rubber rings of different sizes and guide wheels with annular grooves of different sizes, so that this embodiment has good versatility.
[0018] See Figure 4 A positioning groove 11 is provided on the loading roller corresponding to the position where the rubber ring is sleeved, and the inner wall shape of the rubber ring is adapted to the positioning groove.
[0019] See Figure 2 The flip frame is provided with an arc-shaped groove 31, which can abut against the limiting rod, so that the contact area between the two is large and not easy to deform.
[0020] In this embodiment, the flipping state of the flip frame is controlled by the loading cylinder. When the embodiment needs to perform rolling, the loading cylinder pushes the flip frame to rotate until it abuts against the limit rod, and makes the rubber ring on the loading roller abut against the load-bearing roller. Since the position of the limit rod is fixed, the abutment axis distance between the loading roller and the load-bearing roller is fixed. After the rubber ring contacts the load-bearing roller, a certain deformation will occur. The greater the deformation, the greater the contact area between the two, the greater the rolling force, and the more obvious the rolling effect. After the rubber ring is worn, its outer diameter will be slightly smaller, so the rolling force will be smaller, and the thickness change of the webbing will also affect the actual rolling force. In this embodiment, the positioning sleeves on both sides of the rotating rubber ring can be pre-tightened to change the spacing between the two abutting parts to achieve fine adjustment of the outer diameter of the rubber ring. Specifically, when the spacing is reduced, the rubber ring is squeezed, so the outer diameter of the rubber ring tends to increase; when the spacing is increased, the rubber ring tends to rebound to its original state, so the outer diameter of the rubber ring tends to decrease. When this embodiment is not subjected to rolling or needs debugging, the loading cylinder pulls the turning frame to make it leave the limiting rod, and the rubber ring is separated from the bearing roller to avoid the rubber ring from being locally squeezed and deformed for a long time.
[0021] It is obvious to those skilled in the art that the utility model can be changed in many ways, and such changes are not considered to be out of the scope of the utility model. All such modifications obvious to those skilled in the art will be included in the scope of the claims.
