The friction force is inevitably caused by two structures with relative movement tendency. Therefore, bearings are added to these structures for connection to solve the problem of internal friction loss of the mechanism, provide a stable operating environment, and ensure the cloth and the cloth lifting wheel. Synchronous operation to ensure the quality of the fabric.

The present invention will be further described below in conjunction with the accompanying drawings and embodiments, but it is not used as a basis for limiting the present invention.

Embodiment 1: The structure of the active and double passive cloth lifting wheel is shown in FIG. The cloth reel 22 on the cloth reel 23.

In another preferred solution of this embodiment, referring to Fig. 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 and the fixed connection state;

1 shows, the middle of the cloth wheel disc 23 is fixedly welded with a first self-lubricating bearing seat 231, the rotating shaft 21 is inserted into the first self-lubricating bearing seat 231, and the first self-lubricating bearing seat 231 passes between the rotating shaft 21 and the sleeve 231. The lubricating bearing 24 is transitionally connected, the first self-lubricating bearing 24 is fixedly clamped with the first self-lubricating bearing seat 231, and the first self-lubricating bearing 24 is rotatably connected with the rotating shaft 21.

Because the rotating shaft 21 and the cloth wheel 23 have two connections, they are two first self-lubricating bearing seats 231 and the first self-lubricating bearing 24 that are symmetrical in structure;

In this embodiment, the first detachable part 212 includes a plate-like structure in the circumferential direction of the rotating shaft and first bolts 213; On the seat 231, the positioning bolt 213 inserted in the middle of the positioning bolt 213 makes the first detachable part 212 and the shaft 21 realize a fixed connection or interference fit; when the positioning bolt 213 is withdrawn, the first detachable part 212 is separated from the rotating shaft 21. On this basis, in order to make the connection between the bolt and the rotating shaft 21 more compatible, a straight groove 211 is opened on the corresponding position of the rotating shaft 21;

In another preferred solution of this embodiment, the structure of the first detachable part is shown in FIG. For the bearing seat 231, the positioning bolts 213 are installed on the two-section plate-shaped structure, and the same effect as above can also be achieved;

In the second preferred solution, referring to Figures 4 and 5, in this solution, an end cover plate 2222 is replaced with the limit ring 232, and the specific structure is: the middle part of the end cover plate 2222 is provided with a shaft 21 The mounting hole is provided with a threaded hole communicating with it in the circumferential direction, and the threaded hole is threaded to connect the fixing bolt 2221; when in the locked state, tighten the fixing bolt 2221 to abut the shaft 21. When in the released state, only The fixing bolt 2221 needs to be loosened.

The connection structure of the rotating shaft 21 also includes the connection with the cloth dyeing machine head 1; specifically referring to FIG. 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 12 here mainly plays a role in the active state, because in the passive state, due to the existence of the mechanical shaft seal 14, the rotating shaft 21 is stationary, and because it is located outside the dyeing machine head 1, so Only ordinary rolling bearings 12 are needed.

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 stability of the 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 that drives the cloth roller 22 to rotate itself, and the transmission efficiency of the cloth is also easy to run idly;

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 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 great impact on the cloth guiding (The cloth guide roller 22 can independently bear the cloth guide); when the overall structure is in use, it is more fault-tolerant and more flexible.

According to the general idea of the invention, 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 second self-lubricating bearing seat 222 is fixed at the pre-installation position of the cloth wheel disc 23 and the cloth wheel roller 22, and the second self-lubricating bearing 221 is embedded between the second self-lubricating bearing seat 222 and the cloth wheel roller 22 , The second self-lubricating bearing 221 is fixedly clamped with the second self-lubricating bearing seat 222, 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 the bolt 223 is screwed out, both Separate, can rotate with each other.

The following analyzes the normal operation of the cloth-lifting wheel from the active state and the passive state:

In the active state, a power-providing motor and a motor output structure are also required, as shown in the drive motor 11 shown in FIG. 1. The output end of the drive motor 11 is connected to the input end of the rotating shaft 21 by a belt;

In the active state of the cloth lifting wheel, the shaft 21 and the cloth wheel are fixed through the first detachable part 212, and the cloth wheel roller 22 is fixedly connected to the cloth wheel 23 through the second detachable part 224, and the drive motor 11 When the power is output, the entire cloth wheel 23 is rotated together by the action of the shaft 21, thereby driving the cloth set on it to circulate;

It should be noted here that the power of the entire cloth lifting mechanism 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 mechanism and the outside is only the shaft 21 and the cloth dyeing machine. In the connection structure of the head 1, the rolling bearing 12 at the connection at this time plays its due role, reducing the coefficient of friction, and maintaining the stability of the coefficient of friction, thereby ensuring the stability of the cloth-lifting wheel mechanism; Of course, because it is an active drive mode, the adjustment of the cloth travel can be achieved by directly controlling the output power of the motor.

In the 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 sprays the cloth to generate power, and then drives the cloth wheel 23 to rotate around the rotating shaft 21, and the cloth wheel roller 22 guides the cloth and reduces the tension.

In the mechanism at this time, there are three joints that involve friction loss: the cloth roller 22 and the cloth reel 23 and the rotating shaft 21, the rotating shaft 21 and the cloth reel 23; therefore, the second self-lubricating at the connection The bearing 221 and the first self-lubricating bearing 24 play their due role to reduce additional friction loss and ensure that the cloth and the cloth lifting wheel can move in coordination as a whole. In addition, it is worth integrating that the reason why the two bearings use 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 disc have passive rotation) are introduced. On this basis, the "cloth characteristics" can include the material of the cloth according to the characteristics of the cloth. , Surface roughness, thickness, weight and other characteristics, flexible adjustment of multiple operating modes (including the above-mentioned active and dual passive modes), as follows:

Single-passive operation: the first detachable part makes the cloth wheel disc 23 and the rotating shaft 21 rotatably connected, and the second detachable part 224 makes the cloth wheel roller 22 and the cloth wheel 23 fixedly connect; at this time, the role of the cloth Next, 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 is rotatably connected to the cloth reel 23 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.
