Detailed Description
The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.
Example 1: the structure of the double passive cloth lifting wheel is shown in figure 1, and comprises a cloth carrying wheel disc 23, a rotating shaft 21 which is rotatably connected to the middle part of the cloth carrying wheel disc 23, and cloth carrying wheel rollers 22 which are fixed on the cloth carrying wheel disc 23 in an annular array by taking the rotating shaft 21 as a symmetrical center;
the shaft 21 is also rotatably connected to the external machine head 1 of the dyeing machine.
When the cloth winding machine works, cloth winds on the cloth wheel roller 22, and under the action of power of a rear end nozzle spraying on the cloth, the cloth wheel disc 23 moves along with the circulation of the cloth and rotates around the rotating shaft 21.
Based on the above principle, it can be known that the factors influencing the rotation of the cloth carrying rotary disc 23 are mainly embodied on two connecting structures, namely the connection between the rotary shaft 21 and the dyeing machine head 1 and the connection between the cloth carrying rotary disc 23 and the rotary shaft 21.
Therefore, in order to reduce the friction loss on the two connecting structures, a self-lubricating bearing structure is required to be additionally arranged. The self-lubricating bearing can be suitable for the environment in the machine head 1 of the cloth dyeing machine, is not easy to corrode, and has long service life.
As shown in fig. 2, a first self-lubricating bearing 12 is installed between the dyeing machine head 1 and the rotating shaft 21, and the installation structure is as follows: a mounting hole is formed in the pre-mounting position of the outer wall of the dyeing machine head 1 and the rotating shaft 21, and a first self-lubricating bearing seat 11 is mounted on one side of the mounting hole.
The first self-lubricating bearing seat 11 comprises a cover plate part and a connecting part extending outwards from the inner side end face of the cover plate part, a cavity for accommodating the first self-lubricating bearing 12 is formed in the connecting part, and the outer side end face of the cover plate part is fixedly connected to the cloth dyeing machine head 1 through a bolt so as to achieve the effect of convenient disassembly and replacement.
After the first self-lubricating bearing 12 is embedded into the first self-lubricating bearing seat 11, the first self-lubricating bearing 12 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 24 is arranged between the cloth-carrying rotary disc 23 and the rotating shaft 21, and the specific mounting structure is as follows: a second self-lubricating bearing seat 231 is welded in the middle of the cloth-carrying turntable 23, and the rotating shaft 21 penetrates through the second self-lubricating bearing seat 231; as shown in the figure, the second self-lubricating bearing seat 231 is located in the cavity between the rotating shaft 21 and the second self-lubricating bearing seat 231, the second self-lubricating bearing 24 is in interference fit with the second self-lubricating bearing seat 231, and the second self-lubricating bearing seat 231 is rotatably connected with the rotating shaft 21; a limiting ring 25 is arranged on one side of the second self-lubricating bearing 24, which is far away from the second self-lubricating bearing seat 231, and the limiting ring 25 is fixed on the rotating shaft 21 by bolts.
To sum up, the utility model discloses an idea lies in on the basis of carrying cloth wheel (like fig. 1) now, increases the bearing of a set of pivot 21 and the junction of taking cloth rim plate 22 to this reduces the frictional force in the whole mechanism, reduces the kinetic energy loss of taking cloth rim plate 22 in the rotation, thereby makes the cloth advance and more coordinate with nozzle power, improves the effect of dying cloth.
And the most suitable self-lubricating bearing is selected by combining the working environment in the head of the dyeing machine.
Example 2: the overall inventive concept is not different from that of embodiment 1, but is changed in application scenarios.
Referring to fig. 2, in the present embodiment, two pulley discs 23 are provided on one rotating shaft 21, but in actual use, a plurality of pulley discs may be provided.
Referring to fig. 3, the two cloth carrying wheel discs 23 are independent, in this case, the installation stability of the cloth carrying wheel discs 23 needs to be considered, and the length of the joint between the rotating shaft and the head 1 of the cloth dyeing machine can be prolonged, or a bearing seat is directly installed at one end of the two independent rotating shafts close to each other, and then the bearing seat is fixed and connected with the inner wall of the cloth dyeing machine. The mounting structure should be well understood by those skilled in the art and therefore will not be redundantly described here.
In this scenario, based on the overall invention concept, all the joints of the rotating shaft 21 and other structures are connected by self-lubricating bearings, that is, the joints of the two cloth-carrying wheel discs and the rotating shaft 21 are both provided with self-lubricating bearings.
