Description

Technical Field

[0001] The utility model relates to the technical field of drawframe components, in particular to a pressure roller group for a drawframe. Background Art

[0002] A drawframe is an important textile machine, mainly used for the drawing process in textile production. It is a spinning machine that processes several carded or combed sliver into sliver with certain quality requirements. The function of the drawframe is to improve the internal structure of the sliver, thereby enhancing its long-term evenness, reducing the weight unevenness rate, straightening and parallelizing the fibers in the sliver, reducing hooks, making the fineness meet the regulations, and evenly mixing different types or qualities of raw materials to achieve the specified mixing ratio.

[0003] In existing drawframes, the pressure roller group usually has a rubber roller group. When installing the rubber roller, lubricating oil is generally applied to the connection end first and then installed. The purpose is to reduce friction during rotation. However, when the rubber roller rotates continuously at high speed, the lubricating oil is easily heated and lost, resulting in poor operation of the rubber roller. At this time, regular inspection and maintenance are required to ensure a good lubrication state, but regular inspection and maintenance will cause downtime and affect work efficiency. Therefore, it is particularly important to provide a rubber roller group that can automatically replenish lubricating oil. In view of this, we propose a pressure roller group for a drawframe. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, meet the actual needs, and provide a pressure roller group for a drawframe to solve the technical problem that the current guide roller will cause the lubricating oil to be heated and lost during high-speed operation, requiring regular shutdown inspection and maintenance, which affects work efficiency.

Specific embodiments

[0023] The present utility model will be further described below with reference to the accompanying drawings and embodiments:

[0024] Embodiment: A pressure roller set for a drawing frame, see Figures 1 to 5 , including a fixed frame 1 and a rubber roller 2. A plurality of rubber rollers 2 are installed on the fixed frame 1. Lubricating oil boxes 3 are fixedly arranged on the front and rear side surfaces of the fixed frame 1, and lubricating oil is placed inside the lubricating oil boxes 3;

[0025] Connecting rods 201 are fixedly arranged at both the front and rear ends of the rubber roller 2, and the connecting rods 201 pass through the connection holes on the side plates of the fixed frame 1. The rubber roller 2 can be limited by combining with the connecting rods 201 through the connection holes. A plurality of slotted grooves 202 are formed on the rod wall of the connecting rod 201, and the shape of the slotted grooves 202 is trapezoidal. The bottom of the slotted grooves 202 is narrow and the upper side opening is wide. The inclined groove surface facilitates the movement of the lubricating oil. The position of the slotted grooves 202 facilitates the lubricating oil to flow to the inner side position of the connection holes. In this way, when the connecting rod 201 rotates, it can drive the lubricating oil to contact the inner wall of the connection holes, maintaining the lubrication effect of the connection. The angle between the groove surface of the slotted grooves 202 and the outer wall of the connecting rod 201 is an arc angle 203. The setting of the arc angle 203 can form an arc inclined plane, which can form a gap with the connection holes, facilitating the flow of the lubricating oil and facilitating contact with the connection holes. The side end of the connecting rod 201 is installed with a limit screw 204 through a threaded hole. A plurality of protruding parts 4 are arranged on the front and rear side plates of the fixed frame 1. The setting of the protruding parts 4 can prevent the limit screw 204 from contacting the side surface of the fixed frame 1. In this way, it is convenient for the lubricating oil to contact the connecting rod 201, and at the same time, it can also reduce the friction range when the limit screw 204 rotates.

[0026] Specifically, the convex member 4 includes a fixed block 401, and a marble 402 is rotatably installed inside the fixed block 401; this setting facilitates the self-rotation of the marble 402.

[0027] Further, one side of the limit screw 204 close to the side end of the connecting rod 201 is in contact connection with the outer wall of the marble 402; the rotatably arranged marble 402 can rotate synchronously when the limit screw 204 rotates, which can reduce the frictional force of rotation and reduce structural loss.

[0028] Furthermore, the lubricating oil box 3 includes a box body 301, one side of the box body 301 is fixedly connected to the side plate of the fixed frame 1, a cover plate 302 is installed on the outer wall of the upper side opening of the box body 301, a filling block 306 is fixedly provided at the bottom of the inner cavity of the box body 301, and the filling block 306 is attached to the inner wall of the box body 301 and the side surface of the side plate of the fixed frame 1; by providing the filling block 306 in the box body 301, the storage space of the lubricating oil can be reduced, so that the lubricating oil only exists at the position of the connecting rod 201, improving the sufficiency of the use of the lubricating oil.

[0029] Furthermore, slots 303 are longitudinally formed on the upper side surfaces of the left and right side plates of the box body 301, and insertion plates 304 combined with the slots 303 are fixedly provided on the lower side surface of the cover plate 302, and fixing screws 305 are connected between the box body 301 and the insertion plates 304; through the cooperation, it is convenient to disassemble and assemble the cover plate 302, facilitating the assembly operation.

[0030] Furthermore, the upper surface of the filling block 306 is set as a triangular inclined surface 307, and the outer side surfaces of the filling block 306 are all smooth surfaces; through the setting of the triangular inclined surface 307, it is convenient for the lubricating oil to flow and avoid accumulation on the upper surface of the filling block 306.

[0031] Furthermore, an injection hole 308 is longitudinally formed on the plate wall of the cover plate 302, and a sealing plug 309 is installed inside the injection hole 308; through the position of the injection hole 308, it is convenient to add lubricating oil into the box body 301, so that the step of disassembling the cover plate 302 to add lubricating oil can be omitted, avoiding repeated disassembly from affecting the sealing performance.

[0032] Working principle: During use, the connecting rods 201 at both ends of the rubber roller 2 are located inside the lubricating oil box 3. Because the protrusion 4 is set, a gap is left between the limit screw 204 and the side plate of the fixed frame 1, which makes it convenient for the lubricating oil in the box body 301 to contact with the connecting rod 201. The slot 202 set on the side end of the connecting rod 201 can facilitate the lubricating oil to flow into the position of the connecting hole. During the rotation of the connecting rod 201, the setting of the arc angle 203 on the slot 202 can leave a gap between the connecting hole, which makes it convenient for the lubricating oil to flow out and contact the inner wall of the connecting hole. In this way, the lubricating oil can be replenished during the rotation of the connecting rod 201, which makes up for the lubricating oil lost due to overheating of the rubber roller 2 under high-speed rotation, and ensures the lubricity of the connection. Through such a structural setting, regular inspection and maintenance operations can be omitted, and the sustainable use time of the rubber roller 2 can be increased. Lubricating oil can be added at one time through the position of the injection hole 308, which can save the time required for disassembling the rubber roller 2 in sequence to add lubricating oil, is convenient to use, and maintains the good effect of continuous use of the rubber roller 2.

A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present invention, they are all within the protection scope of the present invention.
