Description

Technical Field

[0001] This utility model relates to the field of extrusion roller technology, and in particular to an extrusion roller. Background Technology

[0002] Extrusion rollers are mechanical components widely used in industrial production. They typically refer to a pair or a group of cylindrical rollers with a certain diameter and length. Through mutual squeezing, rolling and other actions, they apply pressure to the material or object placed between them to achieve specific process objectives, such as crushing, compacting, shaping, dewatering, stretching and other operations on the material.

[0003] During long-term use, the surface of the extrusion roller is prone to wear, which leads to a decrease in the extrusion effect and requires replacement. However, the installation of extrusion rollers in the existing technology is usually reinforced with a large number of bolts. Disassembling them one by one will increase production costs and downtime. Furthermore, some extrusion rollers need to adjust the spacing between them when processing different objects, but this adjustment will increase production costs and downtime. Therefore, there is a need to propose an extrusion roller. Utility Model Content

The turntable 6 and the L-shaped ring bar 19 are fixedly connected, and the L-shaped ring bar 19 is rotatably connected to the L-shaped annular groove. The L-shaped annular groove can guide and limit the L-shaped ring bar 19, thereby guiding and limiting the turntable 6. A retaining groove 7 is formed on the side of each of the two turntables 6 that is close to each other. Each slot 7 has a sliding block 8 inside. Both the slot 7 and the block 8 are rectangular. The outer wall of the block 8 fits against the inner wall of the slot 7. The same lower extrusion roller 9 is provided between the two blocks 8.

The left side of the vertical plate 5 is fixedly connected to the right side of the rotary motor 10. The output end of the rotary motor 10 is fixedly connected to a turntable 6 on the left side.

[0024] The output of the rotary motor 10 drives the turntable 6 to rotate, which in turn drives the clamping block 8 to rotate, and then drives the lower extrusion roller 9 to rotate. The left side of each of the two vertical plates 5 is provided with a through adjustment groove. The top surface of each vertical plate 5 is provided with a hollow motor 11. The top surface of the vertical plate 5 is fixedly connected to the bottom surface of the hollow motor 11. The interior of each hollow motor 11 is threaded with a screw 12.

[0027] In this embodiment, when using this device, if it is necessary to adjust the distance between the lower extrusion roller 9 and the upper extrusion roller 17, the hollow motor 11 needs to be operated. The inner rotor of the hollow motor 11 drives the screw 12 to move up and down inside the hollow motor 11, thereby driving the adjusting plate 13 to move up and down, which in turn drives the turntable 14, the slot 15, the block 16, and the upper extrusion roller 17 to move up and down, thus adjusting the distance between the upper extrusion roller 17 and the lower extrusion roller 9. When it is necessary to replace the lower extrusion roller 9 or the upper extrusion roller 17, the rotary motor 2 needs to be operated. The output end of the rotary motor 2 drives the screw 3 to rotate, and the rotation of the screw 3 drives the threaded block 4 to move left and right along the screw 3. This causes the threaded block 4 to move the left vertical plate 5 to the left, allowing the locking block 8 on the lower extrusion roller 9 to disengage from the slot 7 and the locking block 16 on the upper extrusion roller 17 to disengage from the slot 15, thus completing the disassembly. During installation, the locking blocks 8 and 16 on the right side of the new lower extrusion roller 9 and upper extrusion roller 17 are first installed into the right slot 7 or slot 15. Then, the rotary motor 2 is run, causing the output end of the rotary motor 2 to drive the screw 3 to rotate. The rotation of the screw 3 can drive the threaded block 4 to move to the right, thereby moving the left vertical plate 5 to the right. Then, the left locking blocks 8 and 16 are installed into the left slots 7 and 15, completing the installation.
