[0042] Furthermore, the dust cover 2 is hinged with doors on the side and top to facilitate inspection and maintenance.

[0043] When implementing it, Figure 1-4In the embodiment, the top of the assembly box 1 is fixed with a dust cover 2 by bolts, and the bottom of the dust cover 2 is installed with a bottom plate 3. The left side of the bottom plate 3 drives the rotation of the driving spindle 13 through the driving structure, and the right end of the driving spindle 13 drives the rotation of the grinding disc assembly 9. Specifically, the motor 16 drives the driving pulley 17 connected to its output end to rotate, and the driving pulley 17 is connected to the driven pulley 15 through a belt, and the driving spindle 13 is driven to rotate through the driven pulley 15. The right end of the driving spindle 13 drives the rotation of the grinding assembly 9 and grinds with the round tube 28 on the condenser.

The grinding disc 98 is driven to rotate by the stepper motor 97 .

[0046] A roller seat A99 and a roller seat B910 are installed on the side of the turntable 92 below the grinding disc 98. The roller seats A99 and B910 are symmetrically arranged and tilted to form an eight-shaped structure, and grinding bearings 911 are installed on the top of the roller seats A99 and B910 by screws. The grinding bearings 911 cooperate to form a placement groove for the round tube 28 on the condenser. The grinding bearings 911 can support the end of the round tube 28 and rotate with the round tube 28 at the same time.

[0047] During specific grinding, the round tube 28 on the condenser is inserted into the guide hole 8 in the guide nozzle 7 through the opening on the side of the dust cover 2, and extends through the guide hole 8 to the placement groove formed by the two grinding bearings 911, and is fixed in position by abutting against the sides of the roller seat A99 and the roller seat B910.

The outer side of the cloth bag 20 is clamped by a chuck clamp 24, which is convenient for disassembly and installation, and the debris in the dust box 21 is cleaned regularly.

[0049] like Fig.11 As shown, one end of the condenser is connected to a condenser round tube 28, and the condenser round tube 28 needs to be polished and dezincified so that the condenser tube can be firmly welded to the refrigerator side plate to improve the heat dissipation effect.

[0050] like Fig.12 As shown, on the one hand, the roller seat A99 and the roller seat B910 can be installed with a grinding bearing 911 to facilitate the support of the end of the round tube 28 and can rotate with the round tube 28; on the other hand, the roller seat A99 and the roller seat B910 can limit the free end of the round tube 28 to ensure that each round tube 28 is inserted into a certain position, thereby ensuring a certain grinding position.

[0051] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
