Description

Technical Field

[0001] The utility model relates to the technical field of linear motors for driving a printing head, in particular to a linear motor for driving a printing head. Background Art

[0002] In the field of linear motor technology equipment, when an AC power supply is passed through the primary winding, a traveling wave magnetic field is generated in the air gap. The secondary winding will induce an electromotive force and generate current under the cutting of the traveling wave magnetic field. This current interacts with the magnetic field in the air gap to generate electromagnetic thrust.

[0003] The existing linear motor used to drive the printing head drives the printing head connected to the linear motor by sliding the motor on the slide rail, and the linear motor moves back and forth to print.

The magnitude of the friction is related to the weight of the motor. Under the action of friction, the linear motor will produce additional work when moving, resulting in increased energy consumption. At the same time, it will cause the linear motor to overload and cause the motor to heat up, which is not conducive to the linear motor driving the printing head to drive printing.

The sliding seat 3 is provided with:

[0026] The adjusting unit includes a screw rod 4, a side fixed block 401 and a rotating seat 402.

[0027] The extrusion unit includes a moving seat 5, a connecting seat 503 and a ball 504. The moving seat 5 is connected to the rotating seat 402. The rotating seat 402 moves to push the moving seat 5 to move, so that the connecting seat 503 connected to the moving seat 5 moves, and the ball 504 rotatably connected on the connecting seat 503 is pushed to be squeezed with the slide rail 301.

Under the rolling of the ball 504, the friction between the sliding seat 3 and the slide rail 301 is reduced, so that the sliding seat 3 and the motor 2 can move more easily, reduce energy consumption, and reduce the occurrence of heat generation of the motor 2.
