Embodiment

[0012] A kind of EVA glue additive temperature control heating spray device of the present embodiment, as figure 1 As shown, it includes a spray tube 1 and a motor-driven propulsion screw 2 installed in the spray tube 1; an electric heating chip 3 is evenly mounted on the outer wall of the spray tube 1; the electric heating chip 3 is controlled by a central processing unit.

[0013] The input port of the central processing unit is connected to a voltage divider circuit composed of a simple adjustable resistor and a fixed value resistor. The PWM is controlled by this voltage signal, and then the power of the electric heating chip 3 is controlled. The structure is very simple and effective. The adjustable resistance adopts the knob type, which is convenient for manual operation. During operation, the upper opening of the spray cylinder 1 is connected with the additive conveying pipeline, and the additive is injected into the spray cylinder, and then sent out from the bottom op...

Abstract

The invention relates to a temperature-controlled heating spray device of an EVA (ethylene-vinyl acetate copolymer) glue addition agent, belonging to the technical field of high polymer material preparation. The heating spray device comprises a spraying barrel and a propelling screw rod, wherein the propelling screw rod is arranged in the spraying barrel and is driven by a motor, and electrical heating pieces are uniformly pasted on the outer wall of the spraying barrel, and are controlled by a central processing unit.

Description

technical field [0001] The invention relates to an EVA glue additive heating and spraying device, which belongs to the technical field of polymer material manufacturing. Background technique [0002] In the existing EVA film manufacturing process, additives are added to the EVA film by spraying, mixed and heated thoroughly, then extruded by an extruder, and then cooled and formed by pressing rollers. However, the existing sprayer does not have a heating function, so that when colder additives are added to the heated EVA glue, it will cause uneven heating and uneven stirring. Contents of the invention [0003] The technical problem solved by the invention is to provide an additive spraying device with heating function. [0004] In order to solve the above technical problems, the technical solution proposed by the present invention is: a temperature-controlled heating spray device for EVA glue additives, comprising a spray cylinder and a motor-driven propulsion screw arrang...
