Abstract
Description
Technical Field
[0001] This utility model relates to the field of textile equipment technology, and in particular to a tension adjustment mechanism for the leather roller of a combing machine. Background Technology
[0002] When the wool tops pass through the carding machine's rollers, the tension should not be too tight or too loose. This process often requires tension control of the rollers to ensure that the flow rate of the processed wool tops is equal at all points on the continuous production line. This prevents material buildup and breakage, ensuring the quality of the processed product, such as dimensional accuracy, straightness, winding tightness, shape, and material properties, meets standard requirements.
[0003] When adjusting the tension of the carding machine's rollers, the spacing between the rollers is usually adjusted. This necessitates that the rollers be either movable or detachable. Movable rollers often have less secure connections and are prone to loosening over time. Detachable rollers, such as those using bolt connections, make adjusting the tension more complicated.
[0004] In addition, when adjusting the tension of the carding machine's rollers, it is generally necessary to adjust both ends of the rollers together to ensure they are level. However, this method of adjusting the roller ends separately is not only more cumbersome, but also prone to inconsistent adjustment ranges, which can lead to the rollers shifting and becoming less level. Utility Model Content
[0005] In view of this, the purpose of this utility model is to propose a tension adjustment mechanism for the leather roller of a combing machine, so as to solve the problem of cumbersome tension adjustment of the leather roller in the prior art.
[0006] To achieve the above objectives, this utility model provides a tension adjustment mechanism for a carding machine's leather roller, comprising a leather roller bracket on the carding machine and a leather roller rotatably connected to the leather roller bracket. The tension adjustment mechanism further includes:
[0007] Rotary screws are connected to both ends of the roller, and the screws are slidably connected to the outside of the roller bracket. Fasteners are threaded onto the screws to fix them to the roller bracket.
[0008] Furthermore, the rollers are provided in multiples, all of which are equidistant in the horizontal direction and staggered vertically.
[0009] Furthermore, the inner side of the roller bracket is provided with a roller movable groove, and the two ends of the roller are slidably connected in the roller movable groove. The diameter of the two ends of the roller is the same as the width of the roller movable groove, and the length direction of the roller movable groove is vertical.
[0010] Furthermore, the outer side of the roller bracket is provided with a screw movable groove, the inner end of the screw is slidably connected in the screw movable groove, and the diameter of the screw is the same as the width of the screw movable groove, and the length direction of the screw movable groove is vertical.
[0011] Furthermore, the inner side of the fastener is connected with a plurality of balls.
[0012] Furthermore, the screw has an inner groove, and a horizontal tube is movably connected inside the inner groove. The central axis of the horizontal tube is collinear with the central axis of the screw. The horizontal tube is filled with liquid and has an air bubble inside.
[0013] Furthermore, the liquid in the horizontal tube is alcohol, ether, glycerin, water, or a mixture of the above liquids.
[0014] Furthermore, a return spring is provided in the inner groove of the screw, with its two ends connected to the inner end of the inner groove of the screw and the inner end of the horizontal tube, respectively. A screw end cap is also provided at the outer end of the screw, which is fixedly connected to the outer end of the horizontal tube, and the diameter of the screw end cap is larger than the inner diameter of the inner groove of the screw.
[0015] The beneficial effects of this utility model are as follows: 1. By setting screws at both ends of the roller and placing the screws on the outside of the roller bracket, adjusting the roller position only requires adjusting the screw position by attaching it to the outside of the roller bracket, which is more convenient. Fasteners are set on the screws and are threadedly connected to them. Therefore, tightening the fasteners to firmly clamp the roller bracket ensures a secure connection, while loosening the fasteners allows for tension adjustment of the roller, which is very convenient.
[0016] 2. Several rollers are provided, equidistantly arranged horizontally and staggered vertically. Therefore, the tension of the rollers can be adjusted simply by changing the distance between two adjacent rollers vertically. Furthermore, the tension of multiple rollers can be adjusted simultaneously. The tension adjustment is confined within the roller's movable groove and the screw's movable groove, making the adjustment more controllable.
[0017] 3. A level tube is installed inside the screw. The level tube is stored inside the screw and can be pulled out when needed. When not needed, it will automatically retract under the action of a return spring, which is very convenient. The level tube allows the position of the bubble to be judged to determine the level of the screw, and thus the level of the roller, ensuring the accurate positioning of the roller.

Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.
[0027] The first aspect of this utility model is as follows: Figure 1 , Figure 2 and Figure 4 As shown, since the tension adjustment of the carding machine's rollers generally involves adjusting the distance between the rollers, the rollers need to be either movable or detachable. Movable rollers often have less secure connections and are prone to loosening over time. Detachable rollers, for example, using bolt connections, make adjusting the roller tension cumbersome. Therefore, this embodiment provides a roller bracket 101 on the carding machine and a roller 102 rotatably connected to the roller bracket 101. Screws 105 are rotatably connected to both ends of the roller 102, and the screws 105 are slidably connected to the outside of the roller bracket 101. Fasteners 106 are threaded onto the screws 105 to fix them to the roller bracket 101.
[0028] Preferably, the inner side of the fastener 106 is provided with a plurality of balls 112.
[0029] By providing screws 105 at both ends of the roller 102, and with the screws 105 located on the outside of the roller bracket 101, adjusting the position of the roller 102 is much more convenient; simply attach the screws 105 to the outside of the roller bracket 101. Fasteners 106 are provided on the screws 105, and these fasteners are threadedly connected to the screws 105. Tightening the fasteners 106 to firmly clamp the roller bracket 101 ensures a secure connection, while loosening the fasteners 106 allows for tension adjustment of the roller 102, which is also very convenient.
[0030] The inner side of the roller support 101 is provided with a roller movable groove 103. The two ends of the roller 102 are slidably connected in the roller movable groove 103, and the diameter of the two ends of the roller 102 is the same as the width of the roller movable groove 103. The length direction of the roller movable groove 103 is vertical.
[0031] In addition, a screw movable groove 104 is provided on the outer side of the roller bracket 101. The inner end of the screw 105 is slidably connected in the screw movable groove 104, and the diameter of the screw 105 is the same as the width of the screw movable groove 104. The length direction of the screw movable groove 104 is vertical.
[0032] Preferably, there are several rollers 102, all of which are equidistant in the horizontal direction and staggered in the vertical direction.
[0033] Therefore, the tension of the roller 102 can be adjusted simply by changing the distance between two adjacent rollers 102 in the vertical direction. Furthermore, the tension of multiple rollers 102 can be adjusted. Simultaneously, the tension adjustment of the roller 102 is confined within the roller movement groove 103 and the screw movement groove 104, making the adjustment more controllable.
[0034] The second aspect of this utility model is as follows: Figure 1 , Figure 3 and Figure 4 As shown, when adjusting the tension of the carding machine's rollers, it is generally necessary to adjust both ends of the rollers together to ensure they are horizontal. However, this method of adjusting the roller ends separately is not only more cumbersome but also prone to inconsistent adjustment ranges, leading to roller misalignment and insufficient horizontality. Therefore, in this embodiment, a screw inner groove 108 is provided within the screw 105. A horizontal tube 110 is movably connected within the screw inner groove 108, and the central axis of the horizontal tube 110 is collinear with the central axis of the screw 105. The horizontal tube 110 is filled with liquid and contains an air bubble 111.
[0035] Preferably, the liquid in the horizontal tube 110 is alcohol, ether, glycerin, water, or a mixture of the above liquids.
[0036] In addition, a return spring 109 is provided in the inner groove 108 of the screw. The two ends of the return spring 109 are respectively connected to the inner end of the inner groove 108 of the screw and the inner end of the horizontal tube 110. A screw end cap 107 is also provided at the outer end of the screw 105. The screw end cap 107 is fixedly connected to the outer end of the horizontal tube 110, and the diameter of the screw end cap 107 is larger than the inner diameter of the inner groove 108 of the screw.
[0037] Therefore, by setting a horizontal tube 110 inside the screw 105, the horizontal tube 110 is housed within the screw 105 and can be pulled out when needed. When not needed, it will automatically retract under the action of the return spring 109, which is very convenient. By setting the horizontal tube 110, the position of the bubble 111 in the horizontal tube 110 can be used to determine the levelness of the screw 105, and thus the levelness of the roller 102, ensuring the accurate positioning of the roller.
[0038] In summary, this utility model, by providing screws 105 at both ends of the roller 102, and with the screws 105 located on the outside of the roller bracket 101, makes adjusting the position of the roller 102 much more convenient; simply attach the screws 105 to the outside of the roller bracket 101 and adjust their position. Fasteners 106 are provided on the screws 105, and the fasteners 106 are threadedly connected to the screws 105. Tightening the fasteners 106 to firmly clamp the roller bracket 101 ensures a secure connection, while loosening the fasteners 106 allows for tension adjustment of the roller 102, which is very convenient. Several rollers 102 are provided, equidistantly arranged horizontally and staggered vertically. Therefore, adjusting the distance between two adjacent rollers 102 vertically allows for tension adjustment of the roller 102. Furthermore, the tension of multiple rollers 102 can be adjusted simultaneously. Meanwhile, the tension adjustment of the roller 102 is restricted within the roller movement groove 103 and the screw movement groove 104, making the adjustment more controllable. Additionally, a level tube 110 is installed inside the screw 105. The level tube 110 is stored within the screw 105 and can be pulled out when needed; when not needed, it automatically retracts under the action of the return spring 109, which is very convenient. The level tube 110 allows the position of the bubble 111 within it to determine the levelness of the screw 105, and thus the levelness of the roller 102, ensuring accurate roller positioning.
