The following is a further explanation of this creation in conjunction with the drawings and embodiments, but it is not used as a basis for restricting the creation.

Implementation: 1: The structure of the active and double passive cloth lifting wheel is shown in Figure 1. It is set in the head 1 of the dyeing machine and includes a cloth wheel 23, a rotating shaft 21 arranged in the middle of the cloth wheel 23, and a device The cloth reel 22 on the cloth reel 23.

In another preferred solution of this embodiment, referring to Figure 6, in the cloth dyeing machine head 1, two sets of rotating shafts 21 can be independently installed oppositely, and each rotating shaft 21 is equipped with a cloth wheel 23, which is equivalent to Two independent cloth lifting wheels, which work independently, can perform double-channel cloth dyeing work.

A first detachable piece 212 is installed between the rotating shaft 21 and the cloth wheel 23 for switching between the rotating connection state to the fixed connection state; as shown in FIG. 1, the middle part of the cloth wheel 23 is fixedly welded There is a first self-lubricating bearing seat 231, the rotating shaft 21 is inserted into the first self-lubricating bearing seat 231, the rotating shaft 21 and the sleeve 231 are transitionally connected by a first self-lubricating bearing 24, the first self-lubricating bearing 24 and the first The self-lubricating bearing seat 231 is fixedly clamped, and the first self-lubricating bearing 24 is rotatably connected with the rotating shaft 21.

The first self-lubricating bearing 24 is away from the side of the first self-lubricating bearing seat 231, and a limit ring 232 is installed. The limit ring 232 is fixed on the rotating shaft 21 and abuts against the first self-lubricating bearing 24 to limit the position. The axial movement of the first self-lubricating bearing 24.

Because the rotating shaft 21 and the cloth wheel 23 have two connections, the two first self-lubricating bearing seats 231 and the first self-lubricating bearing 24 are symmetrical in structure; in this embodiment, the first detachable part 212 includes In the figure, the plate-like structure and the first bolts 213 are located in the circumferential direction of the rotating shaft; the head and tail ends of the first detachable part 212 are fixedly installed on the first self-lubricating bearing seats 231 on both sides, and the positioning bolts 213 are inserted in the middle. As the positioning bolt 213 advances, the first detachable part 212 is fixedly connected or interference fit with the shaft 21; when the positioning bolt 213 is withdrawn, the first detachable part 212 is separated from the shaft 21. On this basis, in order to make The connection between the bolt and the shaft 21 is more coordinated, and a straight groove 211 is opened on the corresponding position of the shaft 21; in another preferred solution of this embodiment, the structure of the first detachable part is shown in FIG. The plate-shaped structure is arranged in two independent sections, and fixed and separately arranged on the first self-lubricating bearing seat 231 located on both sides. Installing positioning bolts 213 on the two-section plate-shaped structure can also achieve the same effect as above; In a preferred solution, referring to FIG. 4 and FIG. 5, in this solution, an end cover plate 2222 is replaced with the limit ring 232. The specific structure is: a hole for mounting the shaft 21 is opened in the middle of the end cover plate 2222 , The circumferential direction of the hole is provided with a threaded hole communicating with it, and the threaded hole is threaded to connect the fixing bolt 2221; in the locked state, tighten the fixing bolt 2221 to abut the shaft 21, and in the released state, only need to fix the The bolt 2221 can be loosened.

The connection structure of the rotating shaft 21 also includes a connection with the cloth dyeing machine head 1; specifically referring to FIG. 1, a bearing seat 13 is fixed on the outer side wall of the cloth dyeing machine head 1, and a rolling bearing is passed between the bearing seat 13 and the rotating shaft 21 12 Transition connection, the specific rolling bearing 12 is fixedly clamped with the bearing seat 13, and the rolling bearing 12 is rotatably connected with the rotating shaft 21; It is worth mentioning here that, in order to ensure that the cloth dyeing machine head 1 is kept sealed from the outside, a mechanical shaft seal 14 is sleeved on the end of the rotating shaft 21 close to the inner wall of the cloth dyeing machine head 1; the rolling bearing there is 12 is mainly used in the active state, because in the passive state, due to the existence of the mechanical shaft seal 14, the shaft 21 is stationary, and because it is located outside the dyeing machine head 1, only ordinary The rolling bearing 12 is sufficient.

The above is the connection structure of the rotating shaft 21. The installation structure of the rotating shaft 21 is an important component that determines whether the cloth lifting wheel operates actively or passively, and whether it is active or passive. The rotating shaft is a necessary part of force transmission, so the bearing is installed on the connection with the cloth wheel 23 for transition, reducing friction, and stabilizing the friction coefficient as much as possible, so as to ensure the stable transmission of the overall mechanism during operation; Look at the connection structure of the cloth wheel roller 22. When the cloth wheel roller 22 is in the active state, it does not need the freedom of rotation because it directly contacts the fabric winding. If the cloth lifting wheel itself rotates actively, the cloth and the cloth wheel The friction between the rollers 22 will be converted into a part of the force driving the cloth roller 22 to rotate itself, and the transmission efficiency of the cloth is also easy to spin; In the passive state, the cloth wheel roller 22 can be given a degree of freedom to rotate around its own axis. At this time, the power will be distributed to the cloth wheel roller 22 and the cloth wheel disc 23. The cloth wheel roller 22 itself It can take on the function of cloth guiding, and the cloth wheel roller 22 itself is lighter than the cloth wheel 23, so it is more labor-saving to drive it, so when the power of the nozzle drops, it will not have a big impact on the cloth guiding (The cloth guide roller 22 can independently guide the cloth); when the overall structure is in use, it has better fault tolerance and flexibility.

According to the general creative idea, the cloth wheel roller 22 in the passive state is a rotatable structure, so a bearing is also added here to reduce friction. The specific installation method is as follows: the cloth wheel disc 23 and the cloth wheel roller 22 The second self-lubricating bearing seat 222 is fixed in the pre-installation position of the second self-lubricating bearing seat 222 and the second self-lubricating bearing 221 is embedded between the second self-lubricating bearing seat 222 and the cloth roller 22. The bearing seat 222 is fixedly clamped, and the second self-lubricating bearing 221 is rotatably connected with the cloth roller 22.

It also includes a second detachable piece 224. As shown in FIG. 2, the second detachable piece 224 in this embodiment includes a plate-shaped structure fixed in the axial direction of the second self-lubricating bearing housing 222, and a plate-shaped structure located in the middle of the plate-shaped structure. The limit bolt 223 can be screwed with the cloth wheel roller 21 after being screwed into a certain shape to realize the fixed connection between the cloth wheel disc 23 and the cloth wheel roller 21; after screwing out the bolt 223, both Separate, can rotate mutually.

The following is an analysis of the normal operation of the cloth lifting wheel from the active state and the passive state: In the active state, a motor to provide power and a motor output structure are also required. As shown in Figure 1, the drive motor 11 is driven by a belt. Connected to the input end of the rotating shaft 21; in the active state of the cloth lifting wheel, the rotating shaft 21 and the cloth wheel are fixed by the first detachable part 212, and the cloth roller 22 and the belt cloth are connected by the second detachable part 224 The wheel 23 is fixedly connected. When the drive motor 11 outputs power, the entire cloth wheel 23 is rotated together by the action of the rotating shaft 21, thereby driving the cloth set on it to circulate; what needs to be noted here is that the entire cloth lifting wheel mechanism The power comes from two parts, one is the motor, and the other is the jet power of the nozzle. The friction loss between the cloth lifting wheel mechanism and the outside is only in the connection structure of the shaft 21 and the dyeing machine head 1, so it is located at this time. The rolling bearing 12 at the connection has played its due role, reducing the friction coefficient, and maintaining the stability of the friction coefficient, thereby ensuring the stability of the cloth lifting mechanism; of course, because it is an active drive mode, it is not The adjustment of travel can be achieved by directly controlling the output power of the motor.

In passive state, no additional power source is needed; the motor does not work.

At this time, the first detachable piece 212 is separated from the rotating shaft 21 (the rotating shaft 21 is rotatably connected with the cloth wheel 23), and the second detachable piece 224 is separated from the cloth wheel roller 22 (the cloth wheel roller 22 and the cloth wheel disk 23 rotating connection); the nozzle generates power to spray the cloth, and then drives the cloth wheel 23 to rotate around the shaft 21, and the cloth wheel roller 22 guides the cloth and reduces the tension.

In the mechanism at this time, there are three connections that involve friction loss, the cloth roller 22 and the cloth wheel 23 and the rotating shaft 21, the rotating shaft 21 and the cloth wheel 23; therefore, the second self-lubricating at the connection The bearing 221 and the first self-lubricating bearing 24 play their due role, reducing additional friction loss, and ensuring that the cloth and the cloth lifting wheel can move in coordination as a whole. In addition, it is worth integrating that the reason for the two bearings using self-lubricating bearings is that the internal environment of the dyeing machine head 1 is corrosive. In actual operation, it is found that the self-lubricating bearings used here have a longer life and better structural stability. .

Working principle: In the above, the active state and the dual-passive state (that is, the situation in which both the cloth wheel roller and the cloth wheel disk have passive rotation) are introduced. On this basis, multiple operation modes can be flexibly adjusted according to the characteristics of the cloth. The specifics are as follows: Single passive operation: the cloth reel 23 is connected to the rotating shaft 21 by the first detachable part, and the cloth reel 22 is fixedly connected to the cloth reel 23 by the second detachable part 224; Under the action of the cloth, force is applied to the cloth belt roller 22, so that the cloth belt wheel 23 runs together with the cloth.

Active plus single passive: the cloth reel 23 is fixedly connected to the rotating shaft 21 through the first detachable part, and the cloth reel 22 and the cloth reel 23 are rotationally connected through the second detachable part 224.

Active plus dual passive: the first detachable part makes the belt cloth wheel 23 and the rotating shaft 21 rotatably connected, and the second detachable part 224 makes the belt cloth wheel roller 22 and the belt cloth wheel 23 rotatably connect, and the drive motor 11 is turned on to drive The rotating shaft 21 rotates. During operation, the cloth belt wheel 23 rotates on the rotating shaft 21, and the cloth travels while the cloth belt roller 22 rotates.

The cloth is input from the input end of the dosing barrel T1, after being cleaned by the pre-wetting tank T2, the first shrinking tank T3, the second shrinking tank T4, and the washing tank T5, it is output from the output end, in the first shrinking tank T3, The second shrinking tank T4 and the washing tank T5 are equipped with rolling wheel rollers (place A in the figure). The function of the cloth lifting wheel here is to adjust the tension and guide the cloth. Generally speaking, several main drives are required. The rollers are driven to run; the rollers here can be replaced with the cloth lifting rollers in Example 1, which can flexibly adjust the active and driven relationship of each roller, and can be controlled more flexibly according to the lightness of the cloth Drive compensation to adjust the tension.
