[0002] A double-roll rubber calender is an important rubber processing equipment, which is mainly used to calender rubber raw materials into rubber sheets with specific thickness, width and shape. It is widely used in the production of rubber products. For example, the production of yoga mats requires the use of a rubber calender to calender the rubber. However, the installation and disassembly process of the two sets of rollers of the current rubber double-roll calender requires not only the disassembly of the frame, but also the screwing on and off of a large number of bolts, which is not only inconvenient, but also easily causes the loss of bolts. For this reason, we propose a rubber double-roll calender. Utility Model Content

By rotating the second rotating shaft 13, the docking plug plate 25 can be rotated from the rotating insertion groove 16 into the docking insertion groove 15. At this time, loosen the locking nut 12 and rotate the screw 10 to drive the adjusting plate 20 to move to the right again, so that the docking plate 14 can leave the pressure roller body 23. At this time, the pressure roller body 23 can be directly pulled off the first rotating shaft 7. In summary, the device is very simple for the installation and disassembly of the upper pressure roller 21 and the lower pressure roller 22, and does not require the use of a large number of bolts and other tools, which greatly facilitates the replacement and maintenance of the upper pressure roller 21 and the lower pressure roller 22.

[0034] The servo motor 6 drives the first rotating shaft 7 to rotate, thereby driving the upper pressing roller 21 and the lower pressing roller 22 to rotate.

[0035] A front material guide roller frame 27 and a rear material guide roller frame 28 are respectively disposed on the front and rear sides of the central frame 1 .

[0036] The front material guide roller frame 27 and the rear material guide roller frame 28 are used for exporting and importing materials respectively.

[0037] The adjustment mechanism includes a fixing plate 9 on which the bottom of the lower support frame 2 and the top of the upper support frame 4 are installed, and a screw 10 is rotatably installed on the fixing plate 9 and a guide slide bar 11 is fixedly installed, and the screw 10 and the guide slide bar 11 both pass through the adjustment plate 20, and the screw 10 is threadedly connected to the adjustment plate 20, and a locking nut 12 is threadedly installed on the outer side of the screw 10.

[0038] By rotating the screw rod 10, the adjusting plate 20 can be driven to move in cooperation with the guide slide rod 11 to adjust the position of the second rotating shaft 13. When the adjusting plate 20 moves to the leftmost side, the locking nut 12 can be tightened to assist in fixing the adjusting plate 20.

[0039] A spring 19 is connected between the second square rod 18 and the inner wall of the second rotating shaft 13 . One end of the second square rod 18 passes through the second rotating shaft 13 and is connected to a handle 29 .

[0040] When the docking insertion slot 15 and the docking plug plate 25 are inserted into place, the second square plug rod 18 is squeezed into the interior of the second rotating shaft 13. At this time, the spring 19 is compressed, and the second rotating shaft 13 is rotated by the handle 29 to rotate the docking plug plate 25 into the rotating insertion slot 16. At this time, the second square plug rod 18 is aligned with the square slot 24 at the right end of the pressure roller body 23. After releasing the handle 29, under the action of the rebound force of the spring 19, the second square plug rod 18 is automatically inserted into the square slot 24 at the right end of the pressure roller body 23.

[0041] An integrally formed first limit plate 17 is disposed on the inner side of the rotation insertion groove 16 , and an integrally formed second limit plate 26 is disposed on the docking plug plate 25 .

[0042] After the docking plug plate 25 is rotated into the rotating insertion groove 16, the second limiting plate 26 and the first limiting plate 17 coincide with each other, so as to limit the pressure roller body 23 and the docking plate 14 to each other and prevent them from being separated.

[0043] Working principle and use process of the utility model: When installing the upper pressure roller 21 and the lower pressure roller 22, the locking nut 12 is first loosened, and then the screw 10 is rotated. Under the spiral transmission between the screw 10 and the adjusting plate 20, the adjusting plate 20 is driven to move rightward together with the second rotating shaft 13, and then the upper pressure roller 21 and the lower pressure roller 22 are placed between the second rotating shaft 13 and the first rotating shaft 7, and first the square slot 24 at the left end of the pressure roller body 23 and the first square insertion rod 8 on the first rotating shaft 7 are inserted, and then the screw 10 is rotated in the opposite direction to move the adjusting plate 20 back, and the second rotating shaft 13 is rotated by the handle 29 so that the docking insertion groove 15 on the second rotating shaft 13 and the docking insertion groove 15 on the right end of the pressure roller body 23 are aligned with each other. The connecting plate 25 is aligned, and as the adjusting plate 20 moves, the connecting slot 15 and the connecting plug plate 25 are inserted and connected. After being inserted into place, the second square plug rod 18 is squeezed into the inside of the second rotating shaft 13, and the second rotating shaft 13 is rotated by the handle 29 to rotate the connecting plug plate 25 into the rotating inserting slot 16, so that the second limiting plate 26 and the first limiting plate 17 overlap with each other, which plays a role in limiting the second rotating shaft 13 and the roller body 23, and cooperates with the insertion of the first square plug rod 8 and the square slot 24 to initially fix the roller body 23. At this time, the second square plug rod 18 is aligned with the square slot 24 at the right end of the roller body 23, and the handle 29 is released. Under the action of the rebound force of the spring 19, the second square plug rod 18 is automatically inserted into the square slot 24 at the right end of the roller body 23. Finally, the locking nut 12 is retightened to complete the installation of the upper roller 21 and the lower roller 22. When disassembly is required, it is only necessary to pull the handle 29 to drive the second square plug rod 18 to leave the square slot 24. At this time, the handle 29 is turned to drive the second rotating shaft 13 to rotate, so that the docking plug plate 25 can be rotated from the rotating insertion groove 16 into the docking insertion groove 15. At this time, the locking nut 12 is loosened and the screw 10 is turned to drive the adjusting plate 20 to move to the right again, so that the docking plate 14 can leave the roller body 23. At this time, the roller body 23 is directly pulled out from the first rotating shaft 7. In summary, the device is very simple to install and disassemble the upper pressure roller 21 and the lower pressure roller 22, and there is no need to use a large number of bolts and other tools, which greatly facilitates the replacement and maintenance of the upper pressure roller 21 and the lower pressure roller 22. When calendering the rubber, the hydraulic adjustment device 3 drives the upper support frame 4 to adjust the distance between the upper pressure roller 21 and the lower pressure roller 22 according to the calendering thickness, and the material to be calendered is introduced between the upper pressure roller 21 and the lower pressure roller 22 through the rear guide roller frame 28. The upper pressure roller 21 and the lower pressure roller 22 are driven to rotate by the servo motor 6 to calender the material. The calendered material is guided out to the cutting device or the winding device through the front guide roller frame 27.
