[0026] Specific implementation method and principle

[0027] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

"Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0029] The first aspect of the utility model is as follows Figure 1 and Figure 2As shown, the utility model adds a set of tension control devices to the wool top conveying table, which mainly includes a tension adjustment wheel 102 for adjusting the tension of the wool top 01 and a reversing wheel 104 located on both sides of the tension adjustment wheel 102 for adjusting the forward direction of the wool top 01. Among them, the tension adjustment wheel 102 is movably connected to the bracket 101 through the tension control device, and the reversing wheel 104 is fixedly connected to the bracket 101 through the cantilever 103.

[0030] Among them, Figure 3 and Figure 4 As shown, the tension control device is composed of a connecting member 107, a slider 110 and a buffer connection mechanism connected between the connecting member 107 and the slider 110. A movable groove 105 is provided on the bracket 101. The connecting member 107 and the slider 110 are both slidably connected in the movable groove 105. The movable groove 105 is arranged up and down, and the connecting member 107 and the slider 110 are both in contact with the movable groove 105 on the left and right sides and the inner side surfaces. Therefore, the tension control device can only move up and down along the movable groove 105.

[0031] In addition, a fixing bolt 111 is fixedly connected to the slider 110, and the other end of the fixing bolt 111 is located outside the bracket 101 and is threadedly connected to a fastening nut 112. The bracket 101 outside the movable groove 105 is also provided with a through groove 106 that penetrates inside and outside, and the fixing bolt 111 is movably connected in the through groove 106. Therefore, by tightening the fastening nut 112, the slider 110 can be tightly fitted in the movable groove 105, and then the tension control device as a whole is fixed relative to the bracket 101. When the tension needs to be adjusted, it is only necessary to loosen the fastening nut 112 so that the tension control device as a whole can move freely on the bracket 101, and then move the tension adjustment wheel 102 up and down.

[0032] On the other hand, Figure 5 and Figure 6 As shown, a buffer connection mechanism is provided between the connecting member 107 and the slider 110. When the wool strip 01 is conveyed, if the force fluctuates, the pressure of the wool strip 01 on the tension adjustment wheel 102 will also change. At this time, the tension adjustment wheel 102 needs to have a certain buffer.

[0033] Specifically, the buffer connection mechanism includes a fixed cylinder 108 and a telescopic rod 109, the fixed cylinder 108 is fixedly connected to the lower end of the slider 110, the telescopic rod 109 is fixedly connected to the upper end of the connecting member 107, a telescopic groove 113 is provided in the fixed cylinder 108 and the slider 110, and the upper end of the telescopic rod 109 is movably connected in the telescopic groove 113.

[0034] The buffer force may be provided by the elastic force of the spring 114, and the spring 114 is provided in the telescopic slot 113, and the upper and lower ends of the spring 114 are respectively connected to the slider 110 and the telescopic rod 109. Therefore, when the pressure of the wool strip 01 on the tension adjustment wheel 102 changes, the connecting member 107 directly connected to the tension adjustment wheel 102 will also experience a force change, which is then transmitted to the telescopic rod 109 and finally to the spring 114, and the spring 114 can play a buffering role at this time.

[0035] Preferably, air pressure can also be used as a buffer force, and a sealing ring is provided at the connection between the telescopic rod 109 and the telescopic slot 113, and a plurality of micropores 115 are provided on the slider 110, and the telescopic slot 113 is connected to the micropores 115. Therefore, when the pressure of the wool strip 01 on the tension adjustment wheel 102 changes, the force of the connecting piece 107 directly connected to the tension adjustment wheel 102 will also change, and then be transmitted to the telescopic rod 109, causing the telescopic rod 109 to move up and down. At this time, the air in the telescopic slot 113 is not smooth because the aperture of the micropores 115 is very small, so the air pressure in the telescopic slot 113 will play a buffering role similar to that of a spring, and compared with the spring, there is no metal fatigue and a longer service life. DETAILED DESCRIPTION

[0036] In the device of the utility model, the wool strip 01 is first transported through the reversing wheel 104 on the front side of the tension adjustment wheel 102, then connected with the tension adjustment wheel 102, and then through the reversing wheel 104 on the rear side of the tension adjustment wheel 102. During this process, the tension adjustment wheel 102 plays a role in adjusting and controlling the tension of the wool strip 01.

[0037] When the wool strip 01 is subjected to a large force and becomes tight, adjust the position of the tension adjustment wheel 102 upward to release the tension. Specifically, loosen the fastening nut 112 by the handle on the fastening nut 112 so that the tension control device as a whole can move freely on the bracket 101, and then move the slider 110 and the connector 107 upward, so that the tension adjustment wheel 102 will also move upward to release the tension. Finally, tighten the fastening nut 112 by the handle on the fastening nut 112 so that the slider 110 fits tightly in the movable groove 105, thereby fixing the tension control device as a whole relative to the bracket 101.

[0038] If the wool top 01 is loose, the position of the tension adjustment wheel 102 needs to be adjusted to increase the tension. Similarly, by loosening the fastening nut 112 through the handle on the fastening nut 112, the tension control device as a whole can move freely on the bracket 101, and then the slider 110 and the connecting piece 107 are moved downward, so that the tension adjustment wheel 102 will also move downward, thereby increasing the tension. Finally, by tightening the fastening nut 112 through the handle on the fastening nut 112, the slider 110 is tightly fitted in the movable groove 105, and the tension control device as a whole is fixed relative to the bracket 101.

[0039] During the conveying process of the wool strip 01, if the force fluctuates, the pressure of the wool strip 01 on the tension adjustment wheel 102 will also change, and the tension adjustment wheel 102 needs to have a certain buffer. The buffer can be provided by providing a spring 114 in the telescopic groove 113. When the pressure of the wool strip 01 on the tension adjustment wheel 102 changes, the connecting piece 107 directly connected to the tension adjustment wheel 102 will also change in force, which will be transmitted to the telescopic rod 109 and finally to the spring 114. The spring 114 can play a buffering role at this time. Alternatively, a sealing ring is provided at the connection between the telescopic rod 109 and the telescopic groove 113, and the slider 110 is provided with a plurality of micropores 115 connected to the telescopic groove 113, so that the air in the telescopic groove 113 cannot flow in and out smoothly, and the air pressure in the telescopic groove 113 will play a buffering role similar to that of the spring 114.

[0040] Based on the above, the utility model increases the tension of the wool strip 01 by adding a downwardly bent component during the conveying process of the wool strip, and the height of the tension adjustment wheel 102 is adjustable, so that the tension of the wool strip can be simply controlled. The tension adjustment wheel 102 is connected to the bracket 101 through the slider 110 in conjunction with the fixing bolt 111 and the fastening nut 112. The setting is simple and the cost is low. When the tension needs to be adjusted, it is only necessary to move the tension adjustment wheel 102 up and down, and the operation is also simple and convenient. A buffer component is set at the tension adjustment wheel 102. The buffer component can use spring elastic force or air pressure as the buffer force, has a good buffer effect, is simple to set, and has a long service life.
