Description

Drying device for plastic sheets

technical field

The utility model belongs to the technical field of biaxially stretched polystyrene sheet processing, in particular to a drying device for plastic sheets.

Background technique

When producing BOPS (Biaxially oriented polystyrene) sheets, due to process requirements, media such as silicone oil and anti-fogging agents need to be coated on the surface of the product, and then dried in a post-stage oven to obtain the finished product. The improvement of the product and the gradual improvement of the quality requirements, the original equipment can not improve the drying degree of the product again, and the previous drying method will cause the product temperature to be too high to increase the brittleness and reduce the toughness. In this case, the produced product cannot be Satisfy customer needs, that is, the quality is not up to standard.

Utility model content

The purpose of the embodiments of the present invention is to provide a drying device for plastic sheets, which can effectively dry the sheets.

The utility model embodiment is realized like this:

A drying device for plastic sheets, comprising: an oven for drying the sheets and a ventilation mechanism, the ventilation mechanism is arranged at the sheet drying outlet of the oven, the ventilation mechanism includes a fan, a main air supply duct , the upper air nozzle and the lower air nozzle, the fan is connected to the main air supply pipe, the upper air nozzle and the lower air nozzle are respectively connected to the main air supply pipe, the horizontal position of the upper air nozzle is higher than the sheet drying outlet of the oven, and the lower air nozzle The horizontal position is lower than the sheet drying outlet of the oven.

Wherein, there are two upper air nozzles, which are arranged side by side on the same horizontal line.

The embodiment of the utility model constitutes a drying device by adding a ventilation mechanism with an upper tuyere and a lower tuyere on the basis of the oven, so that the temperature of the upper and lower surfaces of the sheet coming out of the oven is reduced and air-dried after passing through the blower mechanism, so that the The surface temperature of the product after baking improves the drying degree of the product surface and improves the overall quality of the product.

detailed description

In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model.

The concrete realization of the present utility model is described in detail below in conjunction with specific embodiment:

As shown in Figures 1 and 2, a drying device for plastic sheets includes: an oven 1 for drying the sheet 5 and a ventilation mechanism, and the ventilation mechanism is arranged at the sheet drying output port of the oven 1 , the ventilation mechanism includes a fan 3, a main air supply duct 2, an upper air nozzle 6 and a lower air nozzle 4, the fan 3 communicates with the main air supply duct 2, and the upper air nozzle 6 and the lower air nozzle 4 communicate with the main air supply duct 2 respectively, so The horizontal position of the upper tuyere 6 is higher than the sheet drying output port of the oven 1 , and the horizontal position of the lower tuyere 4 is lower than the sheet drying output port of the oven 1 . In the figure, there are two upper air nozzles 6 arranged side by side on the same horizontal line. In this way, the drying device of the utility model adds the functions of air cooling and air drying on the basis of the original oven, which speeds up the drying treatment efficiency of the two surfaces of the sheet and improves the production efficiency.

Add air ducts and fans at the product outlet of the original equipment, add two sets of air nozzles above the product at the exit, and add a set of air nozzles below the product. The nozzle blows the upper and lower surfaces of the product. Due to the natural wind and temperature angle after the original fan enters the air, it can cool down the product coming out of the oven equipment. At the same time, the flow of a certain wind speed accelerates the evaporation of moisture on the product surface. It plays the role of accelerating drying. Adding this whole set of ventilation device not only reduces the surface temperature of the product, improves the toughness of the sheet product, but also improves the drying degree of the medium coated on the product surface, thereby improving the overall quality of the product. .

The above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present utility model shall be included in this utility model. within the scope of protection of utility models.
