[0001] The utility model relates to the technical field of thermal transfer equipment, in particular to an automatic pressure thermal transfer device. Background Art

[0002] Existing automatic pressure heat transfer machines generally use hydraulic or pneumatic methods, which are complex in structure and heavy. To solve the above problems, some manufacturers have designed solutions using motor transmission. CN204054923U discloses an automatic clothing ironing machine, which includes a machine base, a base, a work plate, an electric control box, and a heated platen assembly. The work plate is set on the base, and a right-angle reduction gearbox is set on the machine base. The right-angle reduction gearbox includes a housing, which is fixed to the machine base. The housing is provided with a basin gear and a bevel gear. The basin gear and the bevel gear are fixed to the housing by bearings. The basin gear and the bevel gear mesh with each other. A screw nut is set at the center hole of the basin gear. The screw nut cooperates with the screw thread. The screw extends from the bottom of the housing, and the lower end of the screw is fixed to the heated platen assembly. During operation, the servo motor drives the basin gear through the bevel gear to drive the screw nut to rotate. Under the action of the thread, the screw moves up and down, thereby driving the heated platen assembly to move up and down. Technical issues

[0003] Since the lead screw moves up and down, the right-angle reducer needs to be designed with space for the lead screw to move up and down. Moreover, the right-angle reducer composed of cone teeth and bevel teeth takes up a large space, resulting in a large drive mechanism and the need to occupy a large space on the upper side of the machine base, resulting in a large volume and weight of the entire product and high cost. Technical Solutions

[0004] The purpose of the utility model is to solve the problem that the existing automatic pressure heat transfer machine driven by a motor has a large driving mechanism, which leads to the large volume and weight of the entire product, high cost and inconsistent appearance. The problem is solved by fixing the reduction gear on the upper end of the screw rod, fixing the screw rod nut on the hot pressing plate assembly, and connecting the motor to the reduction gear through a transmission tooth component. The driving mechanism is designed to be inside the machine body.
