Abstract
Description
Technical Field
[0001] The utility model relates to the field of bearing removal of a vacuum conditioning machine, in particular to a bearing removal tool set for a vacuum conditioning machine. Background Technique
[0002] Tobacco leaf re-drying refers to the process of baking the preliminarily conditioned raw tobacco again. The main purpose is to adjust the moisture content of the tobacco leaves for safe storage.
[0003] In the process of tobacco leaf vacuum conditioning, an on-line continuous vacuum conditioning machine combines vacuum conditioning through a logistics conveying device to form an uninterrupted automatic production line. The functions of the on-line continuous vacuum conditioning machine are as follows: moderately increasing the temperature and moisture content of the tobacco slices, removing green and miscellaneous odors, loosening the tobacco slices, killing insect eggs, and providing suitable raw materials for the next process.
[0004] Since the tobacco leaf vacuum conditioning process is carried out in a completely vacuum, high-temperature, and high-humidity working environment, the working vacuum degree of the conditioning machine in the working state is ≤666 Pa, the working steam pressure is 0.8 - 1.1 MPa, and the relative humidity is not more than 80%. In the narrow space where the bearing of the vacuum conditioning machine is located, since the use state of the bearing of the vacuum conditioning machine cannot be observed, it often causes destructive damage to the bearing of the vacuum conditioning machine during the maintenance and removal period, that is, the bearing of the vacuum conditioning machine is scattered, and only the outer bearing ring of the bearing of the vacuum conditioning machine remains at the original bearing position, causing great difficulties in the maintenance of the equipment.
[0005] In addition, due to the narrow maintenance space and the lack of specific maintenance and removal tools during removal, violent disassembly is often used during maintenance, ultimately resulting in major equipment failures and major safety hazards. In the prior art, there is no corresponding special tool, and only rely on the personal maintenance skills of equipment maintenance personnel and the proficiency in equipment disassembly for disassembly. Two common methods are as follows;
[0006] (1) Equipment maintenance personnel use tools such as copper bars and hammers to impact the bearing at a 75° oblique angle in the working hole of the main transmission shaft at the rear end face of the bearing installation body of the conditioning machine with only 47 mm, which is only 100 mm away from the working surface of one side of the equipment, that is, the bearing installation body of the conditioning machine, on one side of the equipment working surface, so that the bearing embedded in the bearing installation body of the vacuum conditioning machine is destructively removed under the strong impact force. However, since this maintenance method is a fatal damage to the bearing, it often causes the bearing to be completely damaged, and only the bearing outer ring is stuck in the bearing installation body of the vacuum conditioning machine, thus increasing the maintenance difficulty. Therefore, there are major safety hazards, time-consuming and laborious, increasing production costs, and reducing the effective operation rate of the equipment.
[0007] (2) Equipment maintenance personnel use oxygen-acetylene to cut the bearings embedded in the bearing mounting body of the rehumidifier. First, because open flames (oxygen-acetylene) are used to repair equipment in the production area, safety hazards are increased to a certain extent. Secondly, the use of open flames (oxygen-acetylene) to repair equipment in the production area requires the completion of relevant open flame operation procedures, which invisibly increases the maintenance time of the equipment. Finally, when oxygen-acetylene is used to cut the bearings embedded in the bearing mounting body of the rehumidifier, the bearing mounting surface will be damaged to a certain extent. The high temperature flame generated during the open flame (oxygen-acetylene) cutting operation will also cause secondary annealing of the bearing mounting body of the rehumidifier, thereby affecting the service life of the equipment.

Refer to Figures 1 to 3 and it includes a fixed frame 1 which is adapted to be connected to the bearing installation body 4 of the vacuum conditioning machine. Refer to Figure 1 The shape of the bearing installation body 4 of the vacuum conditioning machine is annular, and an inner cavity is provided in the bearing installation body 4. The inner cavity can be divided into a first inner cavity 42 and a second inner cavity 43 from shallow to deep.

As Figure 8 shown, the bearing 5 is installed in the second inner cavity 43, and the model of the bearing 5 can be a 6208 deep groove ball bearing. Refer to Figure 4, a lifting mechanism 2 is provided in the fixed frame 1. Generally speaking, the lifting mechanism 2 is arranged at the middle position of the fixed frame 1, and a holding mechanism 3 is provided on the lifting mechanism 2. When disassembling the bearing, the lifting mechanism 2 drives the holding mechanism 3 to descend into the second inner cavity 43 of the bearing mounting body 4. At this time, the holding mechanism 3 should also be located in the bearing 5 to be disassembled. Subsequently, the holding mechanism 3 extends outwards to hold the inner wall of the bearing 5, making the bearing in a tensioned state (such as the state shown in Figure 5 ). Then, the lifting mechanism 2 drives the holding mechanism 3 to rise until a part of the bearing 5 enters the first inner cavity 42. Finally, by reaching into the first inner cavity 42 with the hand, the bearing 5 can be taken out. In some cases, the bearing 5 may be severely damaged, resulting in malignant damage or even detachment of the inner wall of the bearing 5 and the balls in the bearing 5, and finally only the outer bearing ring 6 as shown in Figure 9 remains. The disassembly method for the outer bearing ring 6 can still follow the disassembly method for the bearing 5, and their disassembly principles are the same.
