Ultraviolet curing machine

Abstract

The invention discloses an ultraviolet curing machine. The ultraviolet curing machine comprises a machine case, a product conveying roller arranged in the machine case, a plurality of ultraviolet light source groups which are arranged above the product conveying roller, and an air draft device which is arranged on the machine case, wherein the machine case comprises a framework which consists of aplurality of stand columns, a housing arranged on the framework and an access door mounted on the framework; and the framework is divided into an air draft device region on the top, an ultraviolet curing region on the middle part and a control system mounting region on the lower part. According to the ultraviolet curing machine disclosed by the invention, two draft fans are arranged on the top ofthe machine case to separately correspond to the product conveying roller and the ultraviolet light source groups, so that ultraviolet light source group type heat extraction is realized, the servicelife of a lamp tube is prolonged, and a dried product is protected from being heated to deform. The ultraviolet curing machine is novel in model, is reasonable in structure, is large in effective working area, is high in drying speed, is high in production efficiency, is convenient to maintain and regulate, is small in noise, is high in reliability, is low in cost and is low in energy consumption. The surface of the machine case is totally sealed and is sprayed, so that the machine case is attractive and elegant, and is resistant to corrosion.

Description

technical field [0001] The invention relates to an ultraviolet curing machine. Background technique [0002] The working principle of the ultraviolet curing machine is that the ultraviolet light irradiates the special glue to make the glue polymerize and then cure. The ultraviolet curing device generally includes a casing, a product conveying roller, a light source reflector and an ultraviolet light source group. In order to discharge the heat in the casing, an exhaust device is provided on the casing. However, the existing exhaust device has a single structure and can only exhaust the position of the product conveying roller in the cabinet, resulting in the untimely heat dissipation of the ultraviolet light source group and short service life. In large-scale UV curing machines, the exhaust ducts are arranged in a mess, which not only affects the appearance, but also is not easy to maintain. The internal structure is complex and the production cost is high, which is not con...

Problems solved by technology

However, the existing exhaust device has a single structure, which can only exhaust the position of the product conveying roller in the cabinet, resulting in the untimely heat dissipation of the ultraviolet light source group and short service life.

In large-scale UV curing machines, the exhaust ducts are arranged in a mess, which not only affects the appearance, but also is not easy to maintain. The internal structure is complex and the production cost is high, which is not conducive to popularization and use.
