Coordination, thereby improving the dyeing effect.

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.

Embodiment 1: The structure of the dual passive cloth lifting wheel is shown in Fig. 1, which includes a cloth belt wheel 23, a rotating shaft 21 rotatably connected to the middle of the cloth belt wheel 23, and an annular array fixed on the belt cloth wheel with the rotating shaft 21 as a symmetric center The cloth wheel roller 22 on the disc 23;

The rotating shaft 21 is also rotatably connected with the outer cloth dyeing machine head 1.

When working, the cloth is wound on the cloth belt roller 22, and under the power of the spray from the rear nozzle on the cloth, the cloth belt wheel 23 follows the circulation of the cloth and rotates around the rotating shaft 21.

Based on the above principles, it can be known that the factors affecting the rotation of the cloth wheel 23 are mainly reflected in two connection structures, one is the connection between the rotating shaft 21 and the dyeing machine head 1, and the other is the cloth wheel 23 and the rotating shaft. 21's connection.

Therefore, in order to reduce the friction loss on the two connecting structures, a self-lubricating bearing structure needs to be installed. The self-lubricating bearing can be suitable for the environment in the head 1 of the dyeing machine, is not easy to be corroded, and has a long service life.

Specifically, as shown in Fig. 2, a first self-lubricating bearing 12 is installed between the cloth dyeing machine head 1 and the rotating shaft 21. The specific installation structure is as follows: the outer wall of the cloth dyeing machine head 1 and the pre-installation place of the rotating shaft 21 are provided For the mounting hole, first install the first self-lubricating bearing seat 11 on one side of the mounting hole.

The first self-lubricating bearing seat 11 includes a cover plate portion and a connecting portion extending outward from the inner end surface of the cover plate portion. The connecting portion forms a cavity for accommodating the first self-lubricating bearing 12, and the outer end surface of the cover plate portion is fixedly connected by bolts. It is installed on the head 1 of the dyeing machine to facilitate disassembly and replacement.

After the first self-lubricating bearing 12 is embedded in the first self-lubricating bearing seat 11, it is in interference fit with the first self-lubricating bearing seat 11, and the first self-lubricating bearing 12 is rotatably connected with the rotating shaft 21.

A second self-lubricating bearing seat 24 is installed between the cloth turntable 23 and the rotating shaft 21. The specific installation structure is as follows: the second self-lubricating bearing seat 231 is welded in the middle of the cloth turntable 23, and the rotating shaft 24 is connected to the second self-lubricating bearing seat As shown in the figure, the second self-lubricating bearing seat 231 is located in the cavity between the rotating shaft 24 and the second self-lubricating bearing seat 231, the second self-lubricating bearing seat 24 and the second self-lubricating bearing The seat 231 has an interference fit, and the second self-lubricating bearing seat 231 is rotatably connected with the rotating shaft 21; a limit ring 25 is provided on the side of the second self-lubricating bearing seat 24 away from the second self-lubricating bearing seat 231, and the limit ring 25 uses bolts Fixed on the shaft 21.

In summary, the idea of this creation is to add a set of bearings at the connection between the rotating shaft 21 and the cloth wheel 22 on the basis of the existing cloth lifting wheel (as shown in Figure 1) to reduce the friction in the whole mechanism. , Reduce the kinetic energy loss in the rotation of the cloth wheel 22, so that the cloth travel and the nozzle power are more coordinated, and the cloth dyeing effect is improved.

Combined with the working environment in the head of the dyeing machine, the most suitable self-lubricating bearing is selected.

Embodiment 2: There is no difference from Embodiment 1 in the overall inventive idea, but the application scenario is changed.

Referring to FIG. 2, in this embodiment, there are two cloth reels 23 provided on one rotating shaft 21. Of course, in actual applications, there may be more than one.

As shown in Figure 3, the two cloth roulettes 23 are independent. In this case, the installation stability of the cloth roulette 23 needs to be considered. The length of the connection between the rotating shaft and the dyeing machine head 1 can be extended. Or directly install the bearing seat on the end of the two independent rotating shafts close to each other, and the bearing seat is fixedly connected with the inner wall of the dyeing machine. A person of ordinary skill in the art should be able to fully understand the installation structure, so it will not be repeated here.

In this scenario, based on the overall inventive idea, all connections between the rotating shaft 21 and other structures are connected by self-lubricating bearings, that is, the two cloth wheel discs and the rotating shaft 21 are connected with self-lubricating bearings.
