Film dryer unit

Abstract

The invention relates to a film dryer unit. The film dryer unit comprises multiple film dryer bodies, multiple insulation covers, and a heat exchange box for supplying heat to external; one insulationcover covers one film dryer body; all the insulation covers are provided with intake ports and exhaust ports, and communicate with each other in sequence; the intake port of the insulation cover at one end is used for communicating with an air source; and the exhaust port of the insulation cover at the other end is used for communicating with an intake port of the heat exchange box. The film dryer unit can prevent film dryers from generating the condition of losing a lot of heat in the working process, so that the energy utilization rate is increased; all the insulation covers communicate with each other in sequence; carried heat after combustion of gas, introduced from the intake port of the insulation cover at one end, in the first film dryer body is transferred among later film dryer bodies in sequence by multiple stages; and in a similar way, the carried heat after combustion in the first film dryer body is transferred among the later film dryer units in sequence by multiple stages.

Description

technical field [0001] The invention relates to a product packaging mechanical equipment, in particular to a film drying machine unit. Background technique [0002] In daily life, all kinds of beverage bottles are generally made of plastic, and the outer circumference will be wrapped with a packaging film for marking the basic information of the product such as the product name, trademark, and production date. Before the product is formed, these packaging films must be dried and heated in a film dryer before they can be used. The usual practice is to inject the liquid of the packaging film to be processed into the film drying machine, and use coal gas or natural gas to burn and spray high-temperature airflow (the temperature can reach 300-400°C), so that the liquid of the packaging film to be processed can be rapidly shrunk into shape. [0003] Although the burning time is only 8-20 seconds, a lot of heat is emitted during the process. Since the film drying machine is open...

AI Technical Summary

Problems solved by technology

Since the film drying machine is open, there is a lot of heat loss in the process, and the waste is serious. At the same time, the indoor environment is affected, especially when the dryer unit is used in large-scale industrial production.

The drying film box unit in the prior art, on the one hand, due to its open structure design leads to serious heat loss, so it is necessary to increase the gas flow rate and increase energy consumption; on the other hand, it does not collect the lost heat reasonably and effectively use
