Description

Technical Field

[0001] The utility model relates to the field of texturing machines, in particular to a driving support and connection structure for a roller main shaft of a texturing machine. Background Art

[0002] The roller main shaft of a texturing machine has the characteristics of high rotational speed, large load and continuous operation without shutdown. Therefore, its driving support structure is required to be both stable and reliable, and convenient for subsequent maintenance. The traditional structure of the roller main shaft directly extends out of the main wallboard and is supported by a diamond-shaped bearing. However, the load-bearing capacity of this structure can no longer meet the requirements of the current large-spindle models. Once the diamond-shaped bearing is damaged, it will surely wear the outer diameter of the main shaft at the position where the bearing is located, resulting in the scrapping of the entire main shaft. Replacing the entire main shaft requires disassembling and assembling many parts, which is time-consuming and costly.

[0003] Therefore, the inventor of the present case has conducted further research and developed a driving support and connection structure for a roller main shaft of a texturing machine, and this case is thus generated. Content of the Utility Model

[0004] The purpose of the utility model is to provide a driving support and connection structure for a roller main shaft of a texturing machine, which has a stable structure and can bear a greater load.

[0005] In order to achieve the above purpose, the technical solution of the utility model is as follows:

[0006] A driving support and connection structure for a roller main shaft of a texturing machine includes a roller main shaft. The end of the roller main shaft passes through the middle wallboard and is linked with a transmission shaft through a coupling. The transmission shaft is driven to rotate by an actuating device; wherein, the transmission shaft is arranged on the main wallboard through a bearing seat, and two bearings are arranged in the bearing seat to support the transmission shaft.

[0007] Through the above structure, a structural body that can support a greater load is formed, and the stability and reliability are better.

[0008] Further, the roller main shaft is linked with a transition shaft through a first coupling, and the transition shaft is linked with the transmission shaft through a second coupling.

[0009] Through the connection of two groups of couplings and the transition shaft, the coaxiality error caused by the installation of the transmission shaft and the roller main shaft can be better eliminated, and during subsequent maintenance, only one of the couplings needs to be loosened.

[0010] Further, the actuating device is a motor, and the motor is linked with the transmission shaft through a synchronous belt and a synchronous pulley.

[0011] Further, the main wallboard and the middle wallboard are connected through a wallboard connection column.

[0012] Further, the synchronous pulley includes a driving synchronous pulley and a driven synchronous pulley. The driving synchronous pulley is arranged on the output shaft of the motor, and the driven synchronous pulley is arranged on the transmission shaft.

[0013] Further, both the first coupling and the second coupling are elastic diaphragm couplings.

[0014] The coupling can be the elastic diaphragm coupling applied by the applicant in 2023, which has better flexibility and a wider application ability.

[0015] After adopting the above scheme, compared with the prior art, the utility model has the following advantages:

[0016] The bearing seat has a stable structure and can bear a large load, and is more suitable for the transmission requirements of a high-end false twister; the maintenance cost is relatively low, and the disassembly, replacement of parts are convenient and fast. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following further describes the utility model with reference to the drawings and specific embodiments.

[0024] As Figure 1 shown (showing one end of the support connection structure), a transmission support and connection structure for a roller main shaft 14 of a false twister includes a main wallboard 7 and an intermediate wallboard 11. The main wallboard 7 and the intermediate wallboard 11 are connected by a wallboard connection column 8. Among them, a roller main shaft 14 is arranged between the intermediate wallboards 11, and a plurality of rollers are arranged on the roller main shaft 14; one end of the roller main shaft 14 close to the main wallboard 7 is linked with a transition shaft 12 through a first diaphragm coupling 13, and the transition shaft 12 is linked with a transmission shaft 5 through a second diaphragm coupling 10; a driven synchronous pulley 4 is arranged on the transmission shaft 5, and the driven synchronous pulley 4 is linked with a driving synchronous pulley 2 through a synchronous belt 3, and the driving synchronous pulley 2 is arranged on the output shaft of the motor and is driven by the motor 1 to rotate.

[0025] Through the linkage of two couplings, the coaxiality error caused by the installation of the transmission shaft 5 and the roller main shaft 14 can be better eliminated, and during subsequent maintenance, only one of the couplings needs to be loosened to proceed.

[0026] The aforementioned transmission shaft 5 is passed through the main wallboard 7 through the bearing seat 6, and two bearings 9 are arranged in the bearing seat 6 to support the transmission shaft 5. The two bearings 9 are respectively located on both sides of the main wallboard 7; the bearing seat 6 is fixedly connected to the main wallboard 7 through its own flange, forming a structure that can support a large load, with better stability and reliability.

[0027] The aforementioned diaphragm coupling is the prior design CN202320514081.1 of the applicant, and will not be repeated here.
