Object moving device

Abstract

The invention discloses an object moving device used for controlling movement of an object (such as a printing medium), which comprises a first motor, a second motor, a mobile module, a first transmission module, a second transmission module and a control module, wherein the mobile module is used for driving the object to move; the first transmission module is coupled between the first motor and the mobile module and used for transferring the power from the first motor to the mobile module, so as to drive the mobile module to drive the object to move; the second transmission module is coupledbetween the second motor and the mobile module and used for transferring the power from the second motor to the mobile module, so as to drive the mobile module to drive the object to move; and the control module is coupled to the first motor and the second motor and used for selectively starting the first motor or the second motor.

Description

technical field [0001] The present invention relates to an object moving device, in particular to a device with a first motor, a second motor, a moving module and a control module, and the control module selectively activates the first motor or the second motor to The object mover that drives the move module. Background technique [0002] Generally speaking, color printers can be roughly divided into four categories: dot matrix printers, inkjet printers, laser printers, and thermal sublimation (also known as thermal transfer) printers. Among them, thermal sublimation printers use thermal transfer heads (thermal print head) to heat the ribbon, transfer the dye on the ribbon to the object to be printed, and form a continuous color gradation according to the length of heating time or the heating temperature. Dye-sublimation printers are more and more popular in the market because of their excellent printing quality and more continuous tone performance, which can make the print...

Problems solved by technology

[0005] In order to ensure the printing quality, it is hoped that the motor output working in the printing mode has the characteristics of high torque, and in order to improve the printing efficiency, it is hoped that the motor output working in the feeding and unwinding mode has the characteristics of high speed, and the stepping motor is composed of The winding of the stator determines the performance of its speed and torque. However, under the same driving voltage, the performance of the speed and torque is mutually exclusive. That is to say, the stepper motor only has high torque and low speed or low torque and high speed. Output characteristics, and from the above, it can be seen that the existing technology only uses a single stepping motor to drive the active roller to rotate. If the printing quality is considered, the printing efficiency will be reduced, and if high printing efficiency is required, the printing quality will be sacrificed. Therefore, in order to achieve the whole process The performance of high speed and high torque requires the use of high voltage or high current to drive the motor. In this case, in addition to high energy consumption, the volume of the required stepping motor will also be large, and the motor has almost no rest time, it will cause the motor temperature to be too high
