Description

Technical Field

[0001] The utility model relates to the technical field of sewing machine motors, in particular to a long-life sewing machine motor. Background Art

[0002] With the rapid development of social industrialization, the degree of automation of sewing machines is getting higher and higher. Industrial sewing machines are commonly used equipment in garment processing enterprises. The power of industrial sewing machines is driven by an electric motor through a pulley.

[0003] In addition, the application document with publication number CN220492750U mentions a waterproof DC brushless motor. This motor installs a waterproof device on the shell. According to the characteristics of the waterproof and breathable membrane, it can prevent water vapor outside the shell from entering the shell while not hindering the air circulation inside and outside the shell. At the same time, by installing sealing rubber, the through position between the brushless motor and the box cover can be sealed by the sealing rubber to prevent external water vapor from entering the shell and causing a short circuit in the brushless motor. 2. Through the mutual cooperation between the connecting protrusion and the adjusting screw inside the adjusting device, the position of the shell can be adjusted, thereby achieving the adjustment of the position of the brushless motor, and through the mutual cooperation between the limit block, the return spring and the adjusting button, the shell and the connecting device can be limited after the adjustment is completed to prevent the brushless motor from causing the position of the shell to shift after a long period of movement. However, there are still certain defects that need to be optimized. The specific defects are as follows: Although the buffer plate, top rod, auxiliary block and buffer spring in the motor have a shock-absorbing effect to a certain extent, their shock-absorbing effect is limited. Long-term vibration will not only affect the operating stability of the motor, but may also accelerate the wear of the internal components of the motor and shorten the service life of the motor.

[0004] Therefore, it is particularly important to design a long-life sewing machine motor to change the above-mentioned technical defects and improve overall practicality. Utility Model Content

[0005] The purpose of the present utility model is to provide a long-life sewing machine motor to solve the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A long-life sewing machine motor includes a motor body, wherein buffer plates are symmetrically provided at the top and bottom ends of the motor body, the buffer plates are connected to a mounting frame, rotating rods are symmetrically provided inside the mounting frame, the rotating rods are connected to a fixed rod, and a spring damping shock absorber is provided at one end of the rotating rods.

[0011] As a preferred solution of the present invention, a slot is provided inside the front shell, and both ends of the fixing rod, one end of the spring damping shock absorber and the inner side wall of the slot are fixedly connected.

[0012] As a preferred solution of the present invention, a plurality of air holes are provided on the air permeable plate, a heat-conducting fin is provided on one side of each air hole, the buffer column is a rubber column, the exhaust fan assembly includes a battery compartment, an installation frame, and an exhaust fan, the installation frame and the air permeable plate are connected by bolts, and the battery compartment and the exhaust fan are linearly connected.

[0013] As a preferred solution of the present invention, the breathable waterproof device includes a fixing frame, a breathable waterproof membrane, a sealing gasket, and a protective layer. The fixing frame and the rear shell are connected by embedded bolts, and protective layers are provided on both sides of the breathable waterproof membrane.

[0014] As a preferred solution of the present invention, the front shell and the rear shell are connected by bolts, a threaded tube is provided on the connecting block, the connecting block and the sliding rod are fixed in position by a threaded rod, a mounting plate is provided at the external bottom end of the front shell, and a plurality of mounting bolt holes are provided on the mounting plate and the connecting device.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. In the utility model, a long-life sewing machine motor is provided, and the structure of the front housing, the rear housing, the buffer plate, the mounting frame, the rotating rod, the fixed rod, and the spring damping shock absorber is utilized. The upper and lower ends of the motor are limited by arranging the buffer plate. When the motor is working, it generates vibration, and the vibration squeezes the buffer plate to rotate the rotating rod, which slides along the fixed rod and squeezes the spring damping shock absorber to reduce the vibration of the motor. At the same time, the buffer column 205 on one side of the motor is also used to reduce the vibration of the motor. While reducing the vibration, the thermal conductive gel and the thermal conductive fins absorb the heat generated by the motor and discharge the heat from the interior of the housing through the waterproof breathable membrane under the guidance of the exhaust fan assembly. This solves the problem that although the buffer plate, the top rod, the auxiliary block and the buffer spring in the motor play a shock-absorbing role to a certain extent, their shock-absorbing effect is limited. Long-term vibration not only affects the operating stability of the motor, but may also accelerate the wear of the internal components of the motor and shorten the service life of the motor.
