Description

Technical Field

[0001] This utility model relates to the field of cable processing technology, and in particular to a calendering roller structure for wear-resistant treatment of cable surfaces. Background Technology

[0002] Cables are wire products that transmit electrical energy or signals. In the cable extrusion production process, surface abrasion resistance treatment is crucial. Currently, abrasion resistance treatment is often performed on the cable surface using a calendering roller structure located between two cooling water pools after pre-cooling and before final cooling. This structure makes the surface material denser and smoother by high-pressure rolling the cable outer sheath, thereby significantly improving abrasion resistance, mechanical strength and environmental resistance, effectively protecting the internal structure and extending the service life in complex environments.

[0003] A calender is a calendering roller structure used for abrasion-resistant treatment of cable surfaces. To accommodate cables of different sizes, calenders are often equipped with roller gap adjustment mechanisms. The hand-cranked turntable on top is the adjustment drive component. Operators can adjust the roller gap by rotating the turntable. However, during daily operation, the hand-cranked turntable is easily rotated by external forces such as collisions and vibrations, and it is often difficult to detect in time. This will directly cause the roller gap to deviate from the set parameters, resulting in uneven calendering effect on the cable surface and significantly reducing the working quality of the calender.

A sliding sleeve is fitted into the inner cavity of the corresponding limiting groove. Two limiting sliders 211 are symmetrically fixedly connected to the inner wall of the annular lifting plate 26. The limiting groove and the limiting sliders 211 are used to limit the movement trajectory of the annular lifting plate 26. 27. An external threaded tube 27 is fixedly fitted into the outer wall of the vertical rod 23. The external threaded tube 27 is located above the annular lifting plate 26. 3. A drive tube 28 is threaded to the outer wall of the external threaded tube 27. The outer wall of the drive tube 28 has evenly distributed stripes to increase the friction between the drive tube 28 and the operator's fingers. The bottom of the drive tube 28 is a smooth surface. 4. A retaining ring 212 is located above the external threaded tube 27. 12 is fixedly sleeved on the outer wall of the vertical rod 23. The retaining ring 212 is used to prevent the drive tube 28 from completely disengaging from the external threaded tube 27. Annular groove is formed on the top of the upper circular plate 24. Return spring 29 is fixedly connected at one end to the bottom of the inner wall of the annular groove and at the other end to the bottom of the annular lifting plate 26. The return spring 29 is used to drive the annular lifting plate 26 to automatically perform an upward return movement. Alignment groove one is formed on the outer wall of the lower circular plate 22.

[0047] The specific working principle of this utility model will be explained in detail below:

[0048] When the roller gap of the calender does not need to be adjusted, rotating the drive tube 28 counterclockwise will cause it to move upwards on the external threaded tube 27. During this process, the annular lifting plate 26 and multiple synchronous inserts 25 will move upwards synchronously with the drive tube 28 under the action of the return spring 29. When the synchronous inserts 25 are completely disengaged from the synchronous holes, the rotation of the drive tube 28 can be stopped. At this time, no matter how the hand crank 13 is rotated, the rotating rod 12 of the roller gap adjustment mechanism will not rotate. When the roller gap of the calender needs to be adjusted, align the first alignment groove with the second alignment groove, and then rotate clockwise. The drive tube 28 drives the annular lifting plate 26 and multiple synchronous rods 25 to move downward along the trajectory of the limiting slide groove. When the synchronous rods 25 are inserted into the synchronous holes and the drive tube 28 can no longer rotate clockwise, the force applied to the drive tube 28 is removed. At this time, the hand-cranked turntable 13 can drive the rotating rod 12 to rotate, and the roller gap can be adjusted. This ensures that when the roller gap does not need to be adjusted, the hand-cranked turntable 13 cannot act on the rotating rod 12 of the roller gap adjustment mechanism of the calender, thus avoiding the roller gap from being changed due to the accidental rotation of the hand-cranked turntable 13 and improving the working quality of the calender.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
