Description

Technical Field

[0001] This utility model relates to the field of wet-process diaphragm technology, and more specifically to a threading and tensioning structure for a wet-process diaphragm production line. Background Technology

[0002] The production of wet-process diaphragms involves multiple processes such as batching, casting, stretching, extraction, and drying. Among these, the extraction and stretching processes require high-precision traction and tension control of the diaphragm.

[0003] Existing threading and tensioning structures may generate significant meshing impact noise during diaphragm production, affecting the working environment and equipment lifespan. When equipment malfunctions, it is difficult to disassemble and repair quickly, increasing the complexity and time cost of maintenance. Furthermore, the existing structure cannot adjust chain tension in real time, making it difficult to adapt to instantaneous load changes, which may lead to chain slack or excessive tightness, affecting equipment performance. In the event of a hydraulic failure, there are no protective components to avoid the risk of chain breakage, which may result in equipment damage and safety accidents. Utility Model Content

The threading and tensioning structure for a wet diaphragm production line involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Reference Figure 1-5 This utility model provides a threading and tensioning structure for a wet diaphragm production line, including a plate assembly 1, a threading assembly 2 symmetrically installed on one side of the plate assembly 1, a tensioning assembly 3 provided on one side of the plate assembly 1, a protective assembly 4 installed at the bottom of the tensioning assembly 3 on one side of the plate assembly 1, and a fixing bolt 5 provided on one side of the plate assembly 1 and the threading assembly 2.

[0021] The plate assembly 1 includes a side plate 101, a guide groove 102, and a mounting shaft 103. The guide groove 102 is formed on one side of the side plate 101, and the mounting shaft 103 is fixedly inserted through the interior of the side plate 101. Multiple mounting shafts 103 are provided on the side plate 101, which is beneficial for installing the entire device on the machine.

[0022] The threading assembly 2 includes a threading fixing shaft 201, a bushing 202, rolling balls 203, a double-angle involute toothed section 204, and a collar 205. The threading fixing shaft 201 is fixedly installed on one side of the side plate 101. The bushing 202 is movably sleeved on the outside of one side of the threading fixing shaft 201, and multiple bushings 202 are provided on the outside of one side of the threading fixing shaft 201. Multiple rolling balls 203 are provided inside the bushings 202, and the double-angle involute toothed section 204 movably sleeves... The ball bearing 203 is attached to the outside of the bushing 202, and the ball bearing 203 is in contact with the guide fixing shaft 201 and the double-angle involute tooth profile 204. The collar 205 is movably engaged with one side of the inner bushing 202 of the guide fixing shaft 201. The fixing bolt 5 is fixedly installed inside one side of the guide fixing shaft 201, and a fixing block is provided on one side of the guide fixing shaft 201. This facilitates the removal of the collar 205 and the fixing bolt 5, allowing for the disassembly of the guide assembly 2, which is convenient for maintenance and replacement.

[0023] The tensioning assembly 3 includes a hydraulic cylinder 301, a proportional valve 302, a first connecting ring 303, a tensioning fixing shaft 304, a roller 305, and a rotating shaft 306. The hydraulic cylinder 301 is movably sleeved on one side of the side plate 101 via a fixing bolt 5, and the proportional valve 302 is mounted on the top of the hydraulic cylinder 301. A pressure sensor is installed inside one end of the hydraulic cylinder 301. The first connecting ring 303 is fixedly connected to one end of the hydraulic cylinder 301. The tensioning fixing shaft 304 is movably sleeved inside the first connecting ring 303, and a roller 305 is movably sleeved on one side of the tensioning fixing shaft 304. Roller 305 and rotating shaft 306 are fixedly installed on one side of the bottom of hydraulic cylinder 301. A threading assembly 2 with the same structure is provided on the outside of one side of tensioning fixed shaft 304. The threading assembly 2 provided on the outside of tensioning fixed shaft 304 plays a role in adjusting tension. It is convenient to control the start of hydraulic cylinder 301 through proportional valve 302, so that the first connecting ring 303 pushes tensioning fixed shaft 304, roller 305 and threading assembly 2 provided on the outside of tensioning fixed shaft 304 to move along guide groove 102 on one side of side plate 101, so as to adjust the tension on the diaphragm during production.

[0024] The protective component 4 includes a sleeve 401, a rod 402, a second connecting ring 403, and a spring 404. The bottom of the sleeve 401 is movably sleeved on the bottom of one side of the side plate 101 via a fixing bolt 5. The rod 402 is movably sleeved inside the sleeve 401. The second connecting ring 403 is symmetrically installed on both sides of the top of the rod 402. The spring 404 is located inside the sleeve 401 at the bottom of the rod 402. This is beneficial because, in the event of a failure of the hydraulic cylinder 301, the tensioning fixing shaft 304 will not fall directly due to the elastic force of the spring 404, thus avoiding the risk of chain breakage.

[0025] The working principle of this utility model:

[0026] First, the chain is fixed sequentially to the outside of the corresponding double-angle involute tooth profile 204. The hydraulic cylinder 301 is activated by the proportional valve 302 controlled by the external device. The hydraulic cylinder 301 controls the tension fixing shaft 304, the roller 305 and the threading assembly 2 set outside the tension fixing shaft 304 to move along the guide groove 102 on one side of the side plate 101. At the same time, the pressure sensor set on the top of the hydraulic cylinder 301 will monitor the tension of the chain in real time and transmit it to the external control device to facilitate tension control. During the movement, the roller 305 rolls in the guide groove 102 to reduce the friction generated.

[0027] Secondly, if the hydraulic cylinder 301 malfunctions, the threading assembly 2 installed outside the tension fixing shaft 304 will not fall directly to the bottom of the device under the elastic force of the spring 404, thus avoiding the loss of tension control and chain breakage when the hydraulic cylinder 301 malfunctions.

[0028] Finally, after removing the collar 205 and the fixing bolt 5, the threading assembly 2 can be disassembled, which facilitates the maintenance and replacement of the bushing 202, the ball bearing 203 and the double-angle involute tooth profile 204.

[0029] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
