Description

Technical Field

[0001] This utility model relates to a structure for separating the felt from the heating roller in a roller heat transfer machine, and belongs to the field of roller heat transfer machine equipment. Background Technology

[0002] A rotary heat transfer machine applies pressure to a pre-printed pattern on transfer paper using a heated roller. This causes the hot-melt ink or coating on the transfer paper to sublimate or melt at high temperatures, penetrating the substrate surface and forming a durable pattern upon cooling. The temperature is typically 150℃~230℃ (adjusted depending on the material). Under normal operating conditions, the felt blanket is in moving contact with the heating roller. However, in the event of a sudden power outage or equipment malfunction, the felt blanket stops moving and becomes pressed tightly against the heating roller. Since the contact area between the felt blanket roller and the heating roller remains unchanged, the continuous high temperature can easily burn the felt blanket. Summary of the Invention

[0003] Based on the problems described in the background, the problem that this utility model aims to solve is:

[0004] How to prevent the residual heat of the heating roller from burning the stationary felt after the machine suddenly stops working?

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A structure for separating the felt from the heating roller in a roller heat transfer machine includes a separation mechanism and a power mechanism. The separation mechanism includes a movable shaft, a rack, and a rack passage groove. The power mechanism includes a reducer and a transmission gear. Two housings are provided on both sides of the movable shaft. The inner wall of the two housings near the movable shaft has a movable shaft trajectory hole. A rack passage groove is fixed on the inner wall of the housing. The groove of the rack passage groove covers the movable shaft trajectory hole. The two ends of the movable shaft pass through the movable shaft trajectory holes on both sides and are connected to the rack. The rack passes through the rack passage groove.

[0007] The rack has a meshing hole at the top of the rack passage groove. The transmission gear meshes with the rack at the meshing hole. The transmission gears in the two housings are connected by a transmission rod. One of the transmission gears is connected to a reducer. The reducer is equipped with a rotating handle.

[0008] Preferably, the speed reducer is connected to a motor.

[0009] Preferably, the movable shaft is connected to the rack via a fixed cap, and the movable shaft and the fixed cap are rotatably connected.

[0010] Preferably, the rack passage groove is composed of an inverted U-shaped groove and a fixing plate, and fixing plates are fixed on both sides of the bottom of the inverted U-shaped groove; the fixing plates are fixedly connected to the chassis by screws.

[0011] Working principle: The reducer is operated manually or electrically, which drives the transmission gear to rotate. The transmission gear drives the rack to move linearly in the rack groove. The movement of the rack causes the movable shaft to move away from or towards the heating roller. The felt is wrapped around the movable shaft and the fixed shaft. The felt moves with the movable shaft, achieving the effect of the felt sticking to or detaching from the heating roller.

[0012] The beneficial effects of this utility model are:

[0013] This utility model has a simple and durable structure and can withstand long-term operation;

[0014] This invention allows for the separation of the felt and heating roller by rotating a handle after the roller heat transfer machine has stopped working. In the absence of power failure, a motor-controlled reducer can also be used to detach the felt from the roller and apply it firmly; it is convenient and quick.

[0015] This invention can also be used for temporary standby. Simply rotate the handle to detach the blanket from the heating roller to ensure safe standby of the equipment, which is highly safe. Attached Figure Description
