Problems solved by technology

However, due to the faster heat dissipation at both ends of this form, the temperature at both ends of the drum is always lower than the middle temperature, which is likely to cause a large temperature difference in the axial direction of the drum, generally at 5-12°C, which affects the quality of the coating.
And whether the heating device of the prior art is used in a pre-coating type laminating machine or an instant coating type laminating machine, the laminating speed is 40-50 m / min, and the speed is relatively low.

Embodiment Construction

[0028] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0029] see figure 2 As shown, a heating device for a laminating machine proposed by the present invention includes an outer drum 1 and an inner drum 3. The outer drum 1 is a hollow structure, the inner drum 3 is nested inside the outer drum 1, and the outer drum wall of the inner drum 3 is There is a gap of a certain width between the outer drum 1 and the inner side of the barrel wall; the relative position of the outer drum 1 and the inner drum 3 remains fixed; the outer sides of the left and right end faces of the outer drum 1 are respectively provided with a rotating shaft 14, When rotating, the outer cylinder 1 drives the inner cylinder 3 to rotate.

[0030] Two cavities are formed between the outer sides of the lef...

Abstract

The invention discloses a heating device of a film laminating machine and belongs to the field of film laminating machines. According to the technical scheme, heat-conducting media enter a water inlet, pass through a first cavity, flow into a second cavity along the space between an inner roller and an outer roller, flow back to the heating device after returning to a water outlet through a water outlet pipe, and then flow into the water inlet after being heated again by the heating device. In this way, uniform heating is conducted on the outer roller, and circulating utilization of the heat-conducting media is achieved. The heating device of the film laminating machine can greatly increase the operating speed of the film laminating machine.

Description

technical field [0001] The invention relates to the field of laminating machines, in particular to a heating device for a laminating machine. Background technique [0002] Due to the rapid development of the packaging industry, the performance requirements of the packaging industry for post-press processing equipment, including laminating machines, are increasing. Not only the production accuracy of the equipment is increased, but the production efficiency of the equipment is also significantly improved. The laminating machine can be divided into two categories: instant coating laminating machine and pre-coating laminating machine. The ready-to-coat laminating machine includes three parts: gluing, drying, and hot pressing. It has a wide range of applications and stable and reliable processing performance. It is currently the most widely used laminating equipment in China. Pre-coating laminating machine, without gluing and drying parts, small size, low cost, flexible and con...
