[0023] See also Figure 1-4 The present invention provides an embodiment of a calendering roller for metal calendering that is easy to disassemble and assemble, comprising a roller body 1, a rotating shaft 2 is fixedly mounted at the center position of the outer surface of both sides of the roller body 1, a plug-in column 3 is fixedly mounted on the top of the rotating shaft 2, the rotating shaft 2 and the plug-in column 3 are designed as an integrally formed structure, a locking connection block 4 is provided at the top of the plug-in column 3, and no less than three locking blocks 6 are provided on the outer surface of the locking connection block 4. The number of locking blocks 6 in the drawings of the specification of the present invention is four, and the specific number of use can be dynamically increased or decreased according to different usage requirements, and a plurality of locking blocks 6 are distributed circumferentially at equal intervals through the center point of the locking connection block 4;

[0024] An inner plug-in groove 5 adapted to the plug-in column 3 is provided at the center of the locking connection block 4. A bearing 8 is provided on the side of the locking connection block 4 away from the roller body 1. The inner ring of the bearing 8 is provided with an inner locking groove 9 adapted to the locking connection block 4 and the locking clamping block 6.

[0025] With this structural design, when the calendering roller needs to be installed, the locking connection block 4 of the present invention can be sleeved on the outside of the plug-in column 3 through the inner plug-in groove 5. After the locking connection block 4 is sleeved on the outside of the plug-in column 3 of the roller body, the two can be welded to complete the fixed connection between the locking connection block 4 and the roller body 1, so that the roller body 1 and the locking connection block 4 are connected to form an integral fixed structure, thereby ensuring that the subsequent bearing 8 structure is connected through the locking connection block 4;

[0026] In order to ensure the insertion adaptability between the inner locking groove 9 and the locking connecting block 4, the number of grooves in the inner locking groove 9 is the same as the number of the locking block 6;

[0027] After the locking connection block 4 is fixedly connected to the roller body 1, the locking block 6 of the locking connection block 4 can be aligned with the inner locking groove 9 of the bearing 8. After alignment, the locking connection block 4 can be inserted into the inner locking groove 9, so that the roller body 1 of the utility model can be preliminarily connected to the bearing 8 through the locking connection block 4.

[0028] In this embodiment, to ensure that the locking connection block 4 is inserted into the inner locking groove 9 of the bearing 8 and performs a fixed locking operation therebetween, a plurality of circumferentially distributed primary locking holes 7 are formed on the outer surface of the locking connection block 4, and a circumferentially distributed secondary locking holes 10 are formed on the outer surface of the inner ring of the bearing 8.

[0029] Furthermore, the primary locking hole 7 and the secondary locking hole 10 have the same aperture, and both the primary locking hole 7 and the secondary locking hole 10 are threaded through holes;

[0030] Furthermore, a locking washer 11 adapted to the primary locking hole 7 and the secondary locking hole 10 is provided on the outside thereof, and two positioning holes adapted to the primary locking hole 7 and the secondary locking hole 10 are provided on the locking washer 11;

[0031] With this structural design, when the locking connection block 4 is inserted into the inner locking groove 9 of the bearing 8, the outer end surface of the locking connection block 4 is vertically flush with the inner locking groove 9. At this time, the primary locking hole 7 of the locking connection block 4 is obliquely aligned with the secondary locking hole 10 of the inner ring of the bearing 8. For details, please refer to the attached manual. Figure 4 As shown, a locking gasket 11 can be added between the obliquely aligned first-level locking hole 7 and the second-level locking hole 10, so that the two through holes of the locking gasket 11 are aligned with the first-level locking hole 7 and the second-level locking hole 10, and then the locking gasket 11 is fixedly installed between the first-level locking hole 7 and the second-level locking hole 10 by fixing screws, thereby completing the detachable connection between the roller body 1 and the bearing 8 through the locking connecting block 4.

[0032] Working principle: When the calendering roller needs to be installed, the locking connection block 4 of the present invention can be sleeved on the outside of the plug-in column 3 through the inner plug-in groove 5. After the locking connection block 4 is sleeved on the outside of the plug-in column 3 of the roller body, the two can be welded to complete the fixed connection between the locking connection block 4 and the roller body 1, so that the roller body 1 and the locking connection block 4 are connected to form an integral fixed structure, thereby ensuring that the roller body 1 is connected to the subsequent bearing 8 structure through the locking connection block 4;

[0033] After the locking connection block 4 is fixedly connected to the roller body 1, the locking block 6 of the locking connection block 4 can be aligned with the inner locking groove 9 of the bearing 8. The locking block 6 can be inserted and positioned for connection, which has a certain positioning insertion connection effect. After alignment, the locking connection block 4 can be inserted into the inner locking groove 9, so that the roller body 1 of the utility model can be preliminarily connected to the bearing 8 through the locking connection block 4;

[0034] When the locking connection block 4 is inserted into the inner locking groove 9 of the bearing 8, the outer end surface of the locking connection block 4 is vertically flush with the outer end surface of the inner locking groove 9. At this time, the primary locking hole 7 of the locking connection block 4 is obliquely aligned with the secondary locking hole 10 of the inner ring of the bearing 8. For details, please refer to the attached manual. Figure 4 As shown, at this time, a locking washer 11 can be added between the obliquely aligned primary locking hole 7 and the secondary locking hole 10, so that the two through holes of the locking washer 11 are aligned with the primary locking hole 7 and the secondary locking hole 10, and then the locking washer 11 is fixedly installed between the primary locking hole 7 and the secondary locking hole 10 by a fixing screw, so that the roller body 1 can be detachably connected to the bearing 8 through the locking connecting block 4. The provided locking washer 11 can serve as a positioning locking structure between the bearing 8 and the locking connecting block 4, preventing the locking connecting block 4 from falling out of the inner locking groove 9 of the bearing 8, having better structural stability and improving the use effect of the roller;

[0035] Afterwards, the calendering roller structure assembly can be installed on the metal calender through the bearing 8. The roller installation work can be completed quickly through the use of the locking connection block 4 and the bearing 8, which has the characteristic of quick installation.

[0036] When the roller body 1 needs to be disassembled for maintenance, the several fixing screws on the locking gasket 11 can be removed one by one, and then the locking gasket 11 can be removed. At this time, the locking connecting block 4 of the roller body 1 can be pulled out from the inner locking groove 9 of the bearing 8, so that the roller can be quickly disassembled, which is convenient for maintenance and repair. It is easy to use and has the characteristics of quick installation and quick removal. The operation process is simple and maintenance is convenient.

[0037] To sum up, the utility model is provided with a locking connection block 4 that is adaptively connected to the bearing 8 on the side of the roller body 1. The locking connection block 4 can be adaptively connected to the bearing 8, which can extremely conveniently complete the rapid installation and disassembly of the roller body 1. It has the quick disassembly function for inspection and maintenance. The roller structure is easy to disassemble with low difficulty, which effectively improves the overall inspection and maintenance efficiency of the calendering roller, has a good use effect, and the overall structural design is simple and easy to assemble, which is suitable for popularization and use.
