[0035] The above solution will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are used to illustrate the present utility model but not to limit the scope of the present utility model. The implementation conditions adopted in the embodiments can be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are usually the conditions in conventional experiments.

[0036] Refer to Figure 1 , which is the structural schematic diagram of the embodiment of the present utility model, and provides a rolling barrel for a rolling and polishing machine, including a barrel body 1, an upper cover 2, and a locking device and a lifting mechanism provided on the upper cover 2.

[0037] As Figure 2 shown, the barrel body 1 has a regular hexagon longitudinal section, and the upper end surface and the lower end surface of the barrel body 1 extend horizontally.

[0038] As Figure 3 shown, the upper cover 2 is arranged on the upper end surface of the barrel body 1 and is detachably connected to the barrel body 1.

[0039] In order to facilitate the cooperation between the upper cover 2 and the barrel body 1, pressing plates 2-1 extending in the vertical direction are respectively provided at both ends of the upper cover 2 in the width direction. When the upper cover 2 is locked on the barrel body 1, the pressing plates 2-1 can be abutted against both ends of the barrel body 1.

[0040] A locking device for locking the upper cover 2 on the barrel body 1, comprising two locking mechanisms symmetrically arranged on the upper cover 2. Fixing plates 6 cooperating with the locking mechanisms are respectively provided at both ends of the barrel body 1 in the length direction of the upper cover 2. The upper cover 2 is locked on the barrel body 1 by the cooperation of the two locking mechanisms and the fixing plates 6 at both ends.

[0041] The locking mechanism comprises an eccentric shaft assembly 3 and a self-locking pin assembly 4. As Figure 4 and Figure 5 shown, the eccentric shaft assembly 3 comprises an eccentric sleeve 3-1 fixed on the upper cover 2, an eccentric shaft 3-2 inserted through the eccentric sleeve 3-1, and a pressing shaft 3-3 arranged on the side of the eccentric shaft 3-2 close to the self-locking pin assembly 4. A first positioning hole 3-1a matching the self-locking pin assembly 4 is provided on the pressing shaft 3-3, and a second positioning hole 6-1 matching the eccentric shaft 3-2 is provided on the fixing plate 6. When the self-locking pin assembly 4 is positioned on the pressing shaft 3-3 and the eccentric shaft 3-2 is positioned on the fixing plate 6, the locking between the upper cover 2 and the barrel body 1 is realized. Among them, the self-locking pin assembly 4 is prior art and will not be elaborated in this utility model.

[0042] A lifting mechanism, comprising two lifting assemblies 5 fixed on the upper cover 2. Each lifting assembly 5 comprises two connecting plates 5-1 fixed on both radial sides of the eccentric sleeve 3-1 and a lifting ring 5-2 arranged on at least one connecting plate 5-1. When it is necessary to install or disassemble the upper cover 2, the upper cover 2 is lifted by the cooperation of a lifting rod and the lifting ring 5-2.

[0043] In this example, bushings 3-4 are respectively provided at both ends of the inner wall of the eccentric sleeve 3-1 in the length direction. Preferably, the bushings 3-4 can be made of steel sleeves. Arranging the steel sleeves between the eccentric shaft 3-2 and the eccentric sleeve 3-1 can improve the wear resistance.

[0044] In order to facilitate the operation of the eccentric shaft 3-2, an oil injection port 3-1a is provided on the eccentric sleeve 3-1. At the same time, an oil groove 3-2a is provided on the outer wall of the eccentric shaft 3-2. Lubricating oil is injected into the eccentric sleeve 3-1 through the oil injection port 3-1a, which can play a lubricating role and facilitate the operation of the eccentric shaft 3-2. Preferably, the oil groove 3-2a extends spirally along the outer wall of the eccentric shaft 3-2.

[0045] In order to facilitate the limitation of the eccentric shaft 3-2, a limit snap spring 3-5 is sleeved on one end of the eccentric shaft 3-2 close to the fixing plate 6.

[0046] In this example, the fixing plate 6 is in an inverted U shape and both ends are respectively fixed on both sides of the barrel body 1 in the width direction of the upper cover 2.

[0047] In order to facilitate the installation of the fixing plate 6, two mounting blocks 1-1 are respectively provided at both ends of the barrel body 1 in the length direction of the upper cover 2. Both ends of the fixing plate 6 are respectively fixed on the two mounting blocks 1-1. For example, the fixing plate 6 can be fixed on the mounting blocks 1-1 by bolts.

[0048] To improve safety performance and prevent hot air from scalding operators when the upper cover of the drum is opened, a protective plate 1-2 is provided on one side of the drum body 1 in the width direction of the upper cover 2. The lower end of the protective plate 1-2 is fixed to the drum body 1 and the upper end extends above the upper cover 2. Setting the protective plate 1-2 on one side in the width direction of the upper cover 2 facilitates the installation and disassembly of the upper cover 2.

[0049] The working principle of the present utility model is as follows:

[0050] After the tumbling and grinding is completed, the centrifuge stops working. Manually open the self-locking pin assembly 4, connect the extension rod 7 to the pressing shaft 3-3 and drive the pressing shaft 3-3 to rotate (as Figure 6 shown), so that the eccentric shaft 3-2 is disengaged from the fixing plate 6. After both eccentric shafts 3-2 are withdrawn, lower the suspension rod, manually fasten the buckle of the suspension rod to the two lifting rings 5-2 on the upper cover 2, lift the upper cover 2 by raising the suspension rod, manually take out the product, and the abrasive and water in the drum body 1 can be automatically poured into the lower receiving hopper; put in a new grinding product, add abrasive, cleaning agent and water, lower the upper cover 2 by the suspension rod until it reaches the upper end face of the drum body 1, manually loosen the buckle on the suspension rod, and raise the suspension rod; then, manually press the eccentric shaft 3-2 into the second positioning hole 6-1 of the fixing plate 6, and then lock the self-locking pin assembly 4 in the first positioning hole 3-3a on the pressing shaft 3-3, and lock the two eccentric shafts 3-2 to complete the installation of one drum, facilitating subsequent grinding processes.

[0051] In summary, this drum is convenient for installation and disassembly, can reduce labor intensity, and improve production efficiency.
