Description

Technical Field

[0001] The utility model relates to motor equipment, in particular to a motor for a full-automatic paper shredder. Background Art

[0002] A motor is a device that converts electrical energy into mechanical energy. It uses an energized coil to generate a rotating magnetic field and acts on the rotor to form a magneto-electrical rotation torque. Motors are divided into DC motors and AC motors according to the power supply used. Most motors in the power system are AC motors, which can be synchronous motors or asynchronous motors. The motor is mainly composed of a stator and a rotor. The direction of the force movement of the energized wire in the magnetic field is related to the direction of the current and the direction of the magnetic flux lines. The working principle of the motor is that the magnetic field acts on the force of the current to make the motor rotate.

[0003] The motor in the shredder is a high-speed motor. When shredding paper in large quantities, the motor will generate heat. There are also more paper scraps and higher temperatures in the shredder, which poses certain safety hazards.

[0004] In view of the above-mentioned defects, the designers have actively carried out research and innovation in order to create a motor for a fully automatic paper shredder to make it more valuable for industrial use. Summary of the invention

[0005] In order to solve the above technical problems, the purpose of the utility model is to provide a motor for a fully automatic paper shredder.

[0006] The utility model discloses a motor for a fully automatic paper shredder, comprising a motor housing, a magnetic steel being installed in the motor housing, a rotatable rotor being installed in the motor housing, the upper end and the lower end of the motor housing being open, an upper cover and a bottom cover being installed in the openings respectively, a rotor being installed between the upper cover and the bottom cover via a bearing, a mounting head being provided at the rear end of the rotor passing through the bottom cover, and an axial flow fan being fixed on the mounting head.

[0007] This fully automatic paper shredder motor uses an axial flow fan that rotates with the rotor to drive air into the click casing, and then cools the inside of the motor, effectively reducing the temperature of the motor and improving safety during use.

[0008] Furthermore, the bottom cover is provided with a plurality of through slots for air circulation.

[0009] The through slots on the bottom cover facilitate air circulation and improve heat dissipation efficiency.

[0010] Furthermore, a retaining ring is installed at the lower end of the bottom cover, and the axial flow fan is located in the retaining ring.

[0011] The retaining ring installed on the bottom cover plays a protective role to prevent the axial flow fan from hitting other components or objects.

[0012] Furthermore, there is a full circle of ventilation holes on the motor housing near the upper cover.

[0013] The ventilation holes at the upper end of the motor housing facilitate air flow and improve heat dissipation efficiency.

[0014] Furthermore, the motor housing is cylindrical and fits into each other at the docking position.

[0015] The motor housing docking positions fit each other and the structure is stable after molding.

[0016] Furthermore, the position where the motor housing fits is a raised interactive disc.

[0017] The discs that fit on the surface of the motor housing bite into each other to increase the strength after fixation.

[0018] Through the above scheme, the present invention has at least the following advantages: when the motor for the fully automatic paper shredder is in use, the rotation of the motor itself drives the axial flow fan at its tail end to rotate, driving the cold air outside the motor to enter the inside of the motor, thereby cooling the motor and effectively extending the service life of the motor.

[0019] The above description is only an overview of the technical solution of the utility model. In order to more clearly understand the technical means of the utility model and implement it according to the contents of the specification, the following is a detailed description of the preferred embodiments of the present invention in conjunction with the accompanying drawings.
