Variable-speed transmission mechanism of flake thermal-superposition device

Abstract

The invention relates to a variable-speed transmission mechanism of a flake thermal-superposition device, which comprises a variable-speed module, a motor, a switching gear, a first connection gear, a second connection gear and a thermal-compression gear, wherein the first connection gear is engaged with the first-layer gear to enable a thermal-compression roller wheel to rotate at a first rotation speed, and the second connection gear is engaged with the second-layer gear to enable the thermal-compression roller wheel to rotate at a second rotation speed; when the variable-speed module movesto enable the switching gear to engage with the first connection gear, the dynamic of the motor is transmitted to the thermal-compression gear through the switching gear and the first connection gear, thereby enabling the thermal-compression roller wheel to rotate at the first rotation speed; or when the variable-speed module moves to enable the switching gear to engage with the second connectiongear, the dynamic of the motor is transmitted to the thermal-compression gear through the switching gear and the second connection gear, thereby enabling the thermal-compression roller wheel to rotate at the second rotation speed. By controlling the variable-speed module to enable the switching gear to be in contact with different gears, the invention provides the functions of the variable-speed thermal compression and the exit of flakes.

Description

technical field [0001] The invention relates to a thermal lamination device, in particular to a sheet thermal lamination device for thermally pressing two pieces of thermoplastic film and a sheet wrapped therein. Background technique [0002] In daily life, it is often necessary to add a layer of protective film to some fragile paper data, such as documents or photos, to prevent the documents or photos from being damaged. Usually, a heat lamination device is used to clamp the loose-leaf between two protective films to achieve the protective effect. Next, the structure of a conventional sheet thermal lamination apparatus will be described. [0003] Please refer to FIG. 1 , which is a schematic structural diagram of a conventional sheet thermal lamination device. The sheet heat lamination device 10 includes a heat treatment device 20 , a driving pressing device 30 and a conveying channel 40 , wherein the heat treatment device 20 includes an electric heating plate 21 and a he...

However, if the temperature is adjusted arbitrarily, it will cause a waste of time. For example, the original thermal lamination device is used for thermal lamination at a temperature of 100 degrees. When encountering thicker documents that need to be protected at a temperature of 130 degrees, the The temperature is increased to 130 degrees and the thicker document is thermally laminated. At this time, the thermal lamination device after the temperature is raised can only perform thermal lamination at 130 degrees or a higher temperature. Thermal lamination below 130 degrees must wait for the thermal lamination device to cool down before proceeding, so it takes a period of time to wait for cooling

[0007] In view of this, the prior art proposes a sheet thermal lamination device capable of variable speed, which uses different speeds to thermally laminate documents of different thicknesses at a fixed temperature, that is, thicker documents are thermally laminated at a slower speed. Lamination, while thinner documents use faster speed for thermal lamination, but it is more expensive to use the controller to control the variable speed of the motor, which does not meet the cost considerations
