Description

Technical Field

[0001] The utility model relates to the technical field of cigarette production equipment, in particular to a special suit for flexible and efficient bearing disassembly. Background Art

[0002] At present, the leaf air separator is widely used in cigarette thread making to screen the agglomerated tobacco leaves and debris, so as to improve the purity of tobacco leaves and avoid mixing with debris. Before the tobacco leaves enter the air separation box of the leaf air separator, they need to be thrown through a high-speed conveyor. Although the bearings of the roller shaft of the high-speed conveyor are the same size as those of the general conveyor, because the roller shaft of the equipment is always in a high-speed rotating state, more expensive high-speed bearings are generally selected and replaced regularly, and the replaced bearings can still be used for low-speed equipment. Since the high-speed bearings are tightly matched with the conveyor roller shaft, maintenance personnel often have to perform destructive treatment on the high-speed bearings when they are replaced regularly because they are difficult to remove. The maintenance process is labor-intensive and inefficient, and the removed bearings cannot be used again due to damage, which causes a waste of resources to a certain extent. Utility Model Content

DETAILED DESCRIPTION

[0017] The following is a detailed description of an embodiment of the utility model. This embodiment is implemented on the premise of the technical solution of the utility model, and a detailed implementation method and a specific operation process are given, but the protection scope of the utility model is not limited to the following embodiment.

[0018] See also Figures 1 to 4The present embodiment discloses a special set for flexible and efficient disassembly of a bearing 1. The bearing 1 and the bearing base 2 are integrally formed. The special set includes a bearing mounting back plate 3 and a disassembly tool. The bearing base 2 is detachably mounted on the equipment side plate 4 through the bearing mounting back plate 3. Four mounting bolts 5 are fixed on the bearing mounting back plate 3. A countersunk hole 6 is opened on the bearing mounting back plate 3. The mounting bolts 5 are countersunk bolts. The heads of the mounting bolts 5 are welded in the countersunk holes 6 of the bearing mounting back plate 3. The four mounting bolts 5 pass through the four mounting holes 7 of the bearing base 2 upward one by one and are screwed with locking nuts, so that the bearing base 2 and the bearing mounting back plate 3 can be locked and installed. The disassembly tool includes a disassembly base plate 8. The center of the disassembly base plate 8 has a central screw hole, and the four corners of the disassembly base plate 8 have through holes. The main screw 9 is threadedly connected in the central screw hole of the disassembly base plate 8. Four connecting bolts 10 are correspondingly inserted in the four through holes of the disassembly base plate 8. The rods of the four connecting bolts 10 and the rods of the four mounting bolts 5 are detachably connected through four connecting blocks 11 respectively.

[0019] The two ends of the connection block 11 are respectively provided with internal threaded holes 12, which are respectively threadedly connected with the rod of the connection bolt 10 and the rod of the mounting bolt 5. The connection block 11 is in the shape of a regular hexagonal prism, which is convenient for cooperating with a wrench to realize its rotation operation.

[0020] The rod end of the main screw 9 is a pointed end 13 , and the main screw 9 is pressed against the roller shaft end at the center of the bearing 1 through the pointed end 13 .

[0021] Take the bearing 1 on the high-speed conveyor as an example to illustrate the working process of this special set:

[0022] Four waist-shaped holes 14 are opened on the bearing mounting back plate 3, and four waist-shaped holes 14 are opened on the equipment side plate 4 of the high-speed conveyor. Four bolts are respectively passed through the waist-shaped holes 14 of the bearing mounting back plate 3 and the waist-shaped holes 14 on the equipment side plate 4 of the high-speed conveyor and the nuts are tightened to realize the installation of the bearing mounting back plate 3 and the side plate of the high-speed conveyor.

[0023] When the bearing 1 needs to be disassembled, first loosen the nuts installed on the bearing mounting back plate 3 and the equipment side plate 4 of the high-speed conveyor, and loosen the locking bolts installed on the bearing mounting back plate 3 and the bearing base 2. Then connect the four connecting bolts 10 of the disassembly tool with the four mounting bolts 5 of the bearing mounting back plate 3 through four connecting blocks 11, and make the pointed end 13 of the main screw 9 press against the roller end of the center of the bearing 1. Then rotate the main screw 9, and under the action of the thread cooperation between the main screw 9 and the central screw hole of the disassembly base plate 8, drive the disassembly base plate 8 to move outward, and the force is transmitted to the bearing mounting back plate 3 through the four connecting bolts 10, four connecting blocks 11, and four mounting bolts 5 in turn, and pull the bearing mounting back plate 3 outward, then the bearing 1 seat located outside the bearing mounting back plate 3 moves outward together with the bearing 1, so that the bearing 1 gradually separates from the roller shaft. During the whole disassembly process, the bearing 1 is evenly stressed, and no damage is caused to the bearing 1, so that the flexible, efficient, safe and non-destructive disassembly of the bearing 1 is achieved. The disassembled bearing 1 can be further used in low-speed equipment, thereby realizing the reuse of the bearing 1 and saving resources.
