Description

Technical Field

[0001] This utility model relates to the field of roller mill technology, specifically to a coupling protection mechanism for roller mills. Background Technology

[0002] It mainly consists of rollers, roller support bearings, frame, base, screw pressing device and adjusting device, roller disassembly device and drive device, etc. During the operation of the roller mill, a coupling is required to connect the bearings.

[0003] In existing technology, the output shaft of the motor and the input shaft of the reducer are usually connected by a coupling. However, in actual use, the bearings and couplings rotate for a long time during the operation of the roller mill. When the operator needs to operate the roller mill, the operator is prone to accidentally touching the coupling during the rotation, which poses a certain safety hazard. Therefore, it is necessary to improve the coupling protection mechanism of the roller mill to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a coupling protection mechanism for a roller mill to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a coupling protection mechanism for a roller mill, comprising a base, a protection mechanism being provided on the top of the base, and a limit mechanism being provided inside the protection mechanism.

[0006] Preferably, the protection mechanism includes a vertical block, which is fixedly installed on the top of the base. A rotating shaft is rotatably installed inside the vertical block, and a rotating plate is fixedly installed outside the rotating shaft. A first protective plate is fixedly installed on the top of the rotating plate, and a second protective plate is fixedly installed on the inner side of the first protective plate. A baffle is fixedly installed on the top of the base, and the baffle has an clearance groove inside to facilitate the protection of the coupling of the roller mill.

[0007] Preferably, the protection mechanism is provided in two sets, and the two sets of protection mechanisms are symmetrically arranged on the top of the base, which facilitates the comprehensive protection of the coupling and avoids accidental contact between the operator and the coupling.

[0008] Preferably, the limiting mechanism includes a connecting shell, which is fixedly installed inside the rotating plate. A worm gear is rotatably installed inside the connecting shell and is rotatably installed with the rotating plate. A worm wheel meshes with the outside of the worm gear, and a rotating column is fixedly installed inside the worm wheel. The rotating column is rotatably installed with the connecting shell. A limiting plate is fixedly installed at the end of the rotating column away from the connecting shell. A block is fixedly installed at one end of the worm gear. A storage groove is provided inside the rotating plate, and a positioning cylinder is movably installed inside the storage groove. A rotating handle is fixedly installed on the front of the positioning cylinder to facilitate the limiting operation of the rotating plate.

[0009] Preferably, a through hole is provided inside the connecting shell at the position corresponding to the rotating column, and the rotating column is rotatably installed in the through hole to facilitate the rotation of the rotating column and the limiting plate.

[0010] Preferably, the positioning cylinder has a groove at the position corresponding to the block, and the block is inserted into the groove, which facilitates the positioning of the positioning cylinder and the rotation of the block and the worm gear.

[0011] Compared with the prior art, this utility model provides a coupling protection mechanism for a roller mill, which has the following advantages:

[0012] 1. The coupling protection mechanism of this roller mill, through the setting of the protective mechanism, facilitates the rotation of the rotating plate and the first protective plate during use through the setting of the upright block and the rotating shaft, thereby facilitating the cleaning of the first protective plate and the second protective plate, and facilitating the movement of the base by passing it through the bottom of the coupling. The setting of the baffle facilitates the positioning of the first protective plate, and with the cooperation of the clearance groove, it facilitates the subsequent limiting of the first protective plate.

[0013] 2. The coupling protection mechanism of this roller mill, through the setting of the limiting mechanism, facilitates the positioning of the positioning cylinder through the setting of the storage groove during use. By rotating the handle, the block and worm can be rotated, thereby facilitating the rotation of the limiting plate and making it convenient to limit the rotation of the rotating plate. By keeping the positioning cylinder away from the storage groove, the handle is prevented from being rotated by external force, thereby preventing the block and worm from rotating and ensuring the stability of the rotating plate.

[0022] Example 1:

[0023] Please see Figure 1-2 This utility model provides a technical solution: a coupling protection mechanism for a roller mill, including a base 1, a protection mechanism 2 on the top of the base 1, and a limit mechanism 3 inside the protection mechanism 2.

[0024] Furthermore, the protection mechanism 2 includes a stand block 201, which is fixedly installed on the top of the base 1. A rotating shaft 202 is rotatably installed inside the stand block 201. A rotating plate 203 is fixedly installed on the outside of the rotating shaft 202. A first protective plate 204 is fixedly installed on the top of the rotating plate 203.

[0025] Furthermore, the protection mechanism 2 is provided in two sets, and the two sets of protection mechanisms 2 are symmetrically arranged on the top of the base 1, which facilitates the comprehensive protection of the coupling and avoids accidental contact between the operator and the coupling.

[0026] Example 2:

[0027] Please see Figure 3-4 Furthermore, in conjunction with Embodiment 1, the limiting mechanism 3 includes a connecting shell 301, which is fixedly installed inside the rotating plate 203. A worm gear 302 is rotatably installed inside the connecting shell 301 and is rotatably installed with the rotating plate 203. A worm wheel 303 meshes with the outside of the worm gear 302. A rotating column 304 is fixedly installed inside the worm wheel 303 and is rotatably installed with the connecting shell 301. A limiting plate 305 is fixedly installed at the end of the rotating column 304 away from the connecting shell 301. A block 306 is fixedly installed at one end of the worm gear 302. A storage groove 307 is provided inside the rotating plate 203. A positioning cylinder 308 is movably installed inside the storage groove 307. A rotating handle 309 is fixedly installed on the front of the positioning cylinder 308 to facilitate the limiting operation of the rotating plate 203.

[0028] Furthermore, a through hole is provided inside the connecting shell 301 at the position corresponding to the rotating column 304, and the rotating column 304 is rotatably installed in the through hole, which facilitates the rotation of the rotating column 304 and the limiting plate 305.
