Sheet heat polyunit with real-time temperature control function

Abstract

The invention relates to a sheet heat polyunit with real-time temperature control function, which comprises a first long roller, a second long roller, a first long metal sheet, a second long metal sheet, a first electric heating box, a second electric heating box, a contact sensor and a controller. By using the small and thin long metal sheets, the long rollers have the characteristic of quick temperature change; and by matching with the controller and the contact sensor used for detecting the surface temperature of the long rollers, the sheet heat polyunit can achieve the effects of controlling temperature in real time, realizing more stable working temperature and further improving plastic package (hot press) quality.

Description

technical field [0001] The invention relates to a thermal lamination device, in particular to a sheet thermal lamination device with real-time temperature control function for thermally pressing two thermoplastic film sheets and documents wrapped therein. Background technique [0002] In daily life, sheet thermal lamination devices, commonly known as laminating machines, are often used to form protection for paper such as documents or photos. The user uses two thermoplastic film sheets to cover the documents, and then sends the film sheets into the laminator for thermal pressing (commonly known as plastic sealing) to form a protective film on the surface of the document to achieve the effect of protecting the document . [0003] see figure 1 , which is a structural schematic diagram of an existing thermal lamination device for sheets. The sheet heat lamination device 1 includes a heat treatment device 10 , a driving pressing device 11 and a conveying channel 12 , and the ...

Problems solved by technology

However, the plastic sealing machine 2 that reduces the thickness of the heat conduction box 22 has the disadvantage of too fast loss of heat energy, which causes the working temperature of the drum 21 to be unstable, resulting in poor quality of plastic sealing

In addition, the heat conduction box 22 has a large covering range covering the outer edge of the drum 21, which makes the heat conduction box 22 too large and increases the cost of the plastic sealing machine 2
