Gluer, temperature control device and heat conduction mechanism

Abstract

The invention discloses a gluing machine and a temperature control device and a heat conducting mechanism thereof. The gluing machine comprises a rubber roll used for hot pressing against sheets, a heating unit for heating the rubber roll, the temperature control device comprising a control circuit and a temperature sensor, a heat conducting plate comprising a plane which is attached to a plane detection end of the temperature sensor and a cambered surface which is attached to the surface of the rubber roll. The output end of the control circuit is connected with the heating unit to control the work of the heating unit. The output end of the temperature sensor is connected with the input end of the control circuit for transmitting the temperature information of the rubber roll to the control circuit and the input end of the temperature sensor is the plane detection end. The invention can rapidly detect the temperature of the rubber roll of the gluing machine and accurately control the temperature.

Description

technical field [0001] The invention relates to a laminator for laminating at least two layers of film materials, in particular to a gluing machine. Background technique [0002] The gluing machine is a device that places the items to be sealed (documents, pictures, etc.) in the middle of the plastic film and presses them together, also known as a plastic sealing machine or a plastic laminating machine. The laminating film can also be called a plastic sealing film, a card protection film or a shell protection film. Generally, a PET film is used as a base material, coated with a dry glue, and then specially processed. [0003] refer to figure 1 , is a schematic cross-sectional view of a gluing machine in the prior art. The gluing machine 100 includes a housing 110 , an inlet 120 , an outlet 130 , an upper rubber roller 140 , a lower rubber roller 150 , a temperature controller 160 and the like. The upper rubber roller 140 and the lower rubber roller 150 are arranged in par...

AI Technical Summary

Problems solved by technology

[0006] However, even if the flat plate temperature sensor 161 is close to the upper rubber roller 140 and the lower rubber roller 150, since the upper rubber roller 140 and the lower rubber roller 150 are arc surfaces, the temperature sensor 161 is in contact with the upper rubber roller 140 and the lower rubber roller. The contact surface of 150 is still small, and the temperature sensor 161 cannot quickly perceive the temperature changes of the upper rubber roller 140 and the lower rubber roller 150, resulting in the temperature controller 160 being unable to perform accurate temperature control according to the current situation. If the temperature of 150°C is too hot or too cold, it will affect the quality of the glue, and may also lead to the scrapping of the plastic products, resulting in irreparable losses
