Embodiment 1

[0022] Example 1: from figure 1 and figure 2 You can clearly see the special motor for shredders, including: motor 1, fan 2 installed at the output end of motor 1, end cover 3 and insulating sheet 4.

[0023] The non-output end of the motor 1 is provided with an air inlet 5, the output end of the motor 1 is provided with a fan installation chamber 6, and the fan installation chamber 6 is provided with an air outlet 7, and the air inlet 5 and the air outlet 7 arranged at both ends of the motor 1 are connected. .

[0024] The fan 2 is installed on the output shaft 8 of the motor in the fan installation cavity 6 , the fan installation cavity 6 is closed by the end cover 3 , and the output shaft 8 of the motor 1 protrudes from the center hole of the end cover 3 .

[0025] The insulating sheet 4 is inserted on the output shaft 8 of the motor outside the end cover 3 .

Embodiment 2

[0026] Example 2: From image 3 and Figure 4 It can be seen that the basic structure of the special motor for shredders of the present invention is the same as that of Embodiment 1, the only difference being:

[0027] The fan 2 is installed in a fan box 9 made of a cavity box 91 and a cavity cover 92. The fan box 9 is provided with an air outlet 7, and the center of the cavity box 91 is provided with a suction port 5 communicating with the non-output end air inlet 5 of the motor 1. The hole 93 and the chamber cover 92 are provided with a central hole for the output shaft 8 of the motor 1 to pass through. The fan 2 is installed on the output shaft 8 of the motor 1 in the fan box 9, and the fan box 9 is fixed and installed in the fan installation cavity 6 by screws.

Abstract

A special motor for a paper shredder comprises a motor, and an end cover and an insulating sheet which are mounted at the output end of the motor, and is characterized in that an air inlet is formed in the non-output end of the motor, and a fan mounting cavity is formed in the output end of the motor; the fan mounting cavity is provided with an air outlet, and the air outlet is communicated with an air inlet of the motor; the fan is mounted on an output shaft of the motor in the fan mounting cavity; a fan mounting cavity of the motor is sealed by an end cover, and an output shaft of the motor extends out of a center hole of the end cover. The special motor has the advantages that the output shaft of the motor of the paper shredder drives the fan to rotate while driving the paper shredding knife to operate, the size of the special motor is reduced due to the simplified and compact structure, the size of the paper shredder is further reduced, and equipment manufacturing cost is reduced. Due to the fact that the fan is arranged at the output end of the motor, air is sucked in from the non-output end of the motor when the fan operates, cold air is conveyed to the operating motor and then exhausted from the output end of the motor, the refrigerating effect is better than that of the prior art, and heat dissipation of the motor is better facilitated.

Description

technical field [0001] The invention relates to a paper shredder, in particular to a special motor for the paper shredder. Background technique [0002] A paper shredder is a kind of equipment that starts frequently and is sometimes blocked and overloaded. The overloaded operation of the motor will cause the current to exceed the rated value for a long time, resulting in overheating of the motor, reducing the insulation of the winding, and eventually causing the motor to burn out; It will cause the motor bearing to heat up and shorten the life of the motor. It can be seen that the motor is the core component of the paper shredder, and its overload and heat generation will directly affect the performance and normal operation of the paper shredder. In order to reduce the heat generated by the overload operation of the shredder motor, the existing special motor for the shredder is usually connected to the fan box 9 composed of the cavity box 91 and the cavity cover 92 through ...
