Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.

It is to be noted that unless otherwise specified, technical or scientific terms used herein shall have the ordinary meaning as understood by those skilled in the art to which the present invention belongs.

As shown in fig. 1, the present embodiment provides a steel ball flashing machine, which includes a box 1 and a workbench assembly 2 connected above the box 1, a motor is arranged in the box 1, and the motor is in transmission connection with a rotating shaft 3 of the workbench assembly 2 through belt transmission. The shell of the motor is distributed with a plurality of grooves 4 distributed along the circumferential direction, and all the grooves 4 are parallel to the rotor of the motor. Specifically, the rotor of the motor is vertically upward, and the other end of the motor is fixed on the bottom wall of the box body 1. And the grooves 4 are uniformly distributed on the outer surface of the shell, and the specific number of the grooves 4 is determined according to the actual diameter of the shell.

As shown in fig. 2 to 4, in order to meet the heat dissipation requirement of the motor in the case of long-time operation, the present embodiment further includes a heat exchanger 5, a water tank 6, a heat absorption pipe 7, and a water pump 8. A heat absorption tube 7 is fixedly connected in each groove 4, and the heat absorption tubes 7 are fixedly connected with the grooves 4 through heat conduction silicone grease. The heat-conducting silicone grease enables the connection between the heat absorbing pipe 7 and the groove 4 to be tighter, and the effective contact area is increased. In order to further improve the sealing performance, a cover 9 covering the outer surface of the motor casing is further included for sealing all the heat absorbing pipes 7 in the corresponding grooves 4. The cover 9 can effectively prevent the heat exchange between the heat absorption pipe 7 and the air in the box body 1, so that most heat generated by the motor is absorbed by the heat absorption pipe 7, and the heat dissipation efficiency of the motor is further improved.

The heat exchanger 5 is fixedly arranged on the outer side wall of the box body 1, the water tank 6 is fixedly connected to the upper surface of the heat exchanger 5, and a heat insulation pad 10 is arranged between the water tank 6 and the heat exchanger. The heat insulation pad 10 can effectively prevent the heat of the heat exchanger 5 from being transferred to the water tank 6, and the outer surface and the inner surface of the water tank 6 are both sprayed with heat insulation coatings, so that the heat insulation effect of the water tank 6 is improved, and the heat transfer between the water tank 6 and the ambient air is reduced. The water pump 8 is fixed in the water tank 6; a heat absorption pipe 7 is fixedly connected in each groove 4, all the heat absorption pipes 7, the water tank 6, the water pump 8 and the heat exchanger 5 are sequentially connected in series to form a circulation loop, the water pump 8 drives cooling liquid to circulate, and then the heat absorption pipes 7 absorb heat of the motor and transfer the heat to the heat exchanger 5. Specifically, the lower end water inlet of the heat exchanger 5 communicates with the corresponding heat absorbing pipe 7 through a conduit, and the upper end water outlet of the heat exchanger 5 communicates with the water tank 6 and protrudes from the top wall of the water tank 6. The water pump 8 is fixed on the bottom wall of the water tank 6, and the water outlet of the water pump 8 is communicated with the corresponding heat absorption pipe 7 through a guide pipe. The lower coolant liquid of bottom temperature in the water tank 6 is poured into heat-absorbing pipe 7 by water pump 8 in, and the coolant liquid gets into heat exchanger 5 after absorbing the heat and cools down, then flows back to in the water tank 6. The cooling liquid in the water tank 6 is always kept at a lower temperature, the cooling liquid at the lower temperature is collected at the bottom of the water tank 6, the temperature of the cooling liquid at the upper part of the water tank 6 is higher than that of the cooling liquid at the bottom, and therefore the water pump 8 always cools the cooling liquid at the lower temperature and injects the cooling liquid into the heat absorption pipe 7, so that the heat dissipation efficiency of the motor is guaranteed.

In order to improve the cooling efficiency of the heat exchanger 5, two fans 11 are disposed on the side of the heat exchanger 5, but not limited to two fans 11. As many fans 11 as possible are provided according to the heat dissipation surface area of the heat exchanger 5 to improve the heat dissipation efficiency of the heat exchanger 5. In addition, in order to increase the circulation speed of the cooling liquid and to improve the heat radiation efficiency of the motor, a booster pump 12 is provided in a pipe of a lower water inlet of the heat exchanger 5. Because the whole water circulation pipeline is long, the problems of insufficient pressure and small flow of the water pump 8 are solved, and the cooling liquid is ensured to circulate at a large flow.

The two fans 11 directly blow on the heat dissipating surface of the heat exchanger 5, so as to quickly transfer the heat of the heat exchanger 5 to the surrounding air, so that the temperature of the cooling liquid flowing through the heat exchanger 5 is quickly reduced for cooling, and finally the cooling liquid flows back to the water tank 6 to enter the next circulation, and the circulation is continued. Even if the motor is in a long-time working state, the heat of the motor can be transferred to the ambient air in time, the existing passive heat dissipation is converted into active heat dissipation, the heat dissipation efficiency is greatly improved, the possibility of burning out a coil is reduced, and the processing efficiency is favorably improved.
