Embodiment Construction

[0014] Such as figure 1 As shown, the static mixing device according to the embodiment of the present invention is arranged on both sides of the sandwich panel edge banding production line, figure 1 Taking the left side as an example, the working principle of the left and right sides is the same, including the raw material mixer 11, the air compressor 12, the air filter 13, and the air pipeline 14, the outlet of the raw material mixer 11 and the sandwich panel The position of sealing edge 15 is corresponding.

[0015] In addition, it also includes a first raw material pipeline 21, which communicates with the feeding pipeline of the first raw material tank 23 through a tee 22, and the first raw material tank 23 pumps the first raw material 26 into the raw material tank through the material pump 25, and passes the first raw material The air compressor 24 sends compressed gas into the first raw material tank, and sends the raw materials in the tank into the raw material mixer. ...

Abstract

The invention discloses a method for statically mixing raw materials for a banding production line of a sandwich panel. A raw material mixer is respectively arranged on each of the two sides of the banding production line of the sandwich panel, wherein the raw material mixer is provided with a compressed air inlet, a first raw material inlet, a second raw material inlet and a discharging port; an air compressor is utilized to feed compressed air into the raw material mixers; and the compressed air is utilized to mix raw materials fed into the raw material mixers and then blow the raw materials to to-be-banded side edge of the sandwich panel from the discharging port. According to the method, the compressed air is utilized to directly spray the chemical raw materials from a spraying tube through the discharging port, so that the phenomena of increasing the temperature of the chemical raw materials and plugging a discharging pipeline caused by a process of mixing the chemical raw materials by a stirrer under the control of a motor are avoided, the chemical reaction time of the chemical raw materials is balanced and stable, and the proportion of the raw materials is finer than that of foam cells.

Description

technical field [0001] The invention relates to a raw material mixing method, in particular to a raw material static mixing method used in a sandwich panel edge banding production line. Background technique [0002] In the existing sandwich panel production lines, such as metal surface rock wool sandwich panels and metal surface glass wool sandwich panel production lines, both sides of the sandwich panels need to be edge-sealed with polyurethane. [0003] However, the existing edge banding equipment uses a motor-controlled agitator to stir the chemical raw materials, and the temperature generated by the agitator during the stirring process will speed up the reaction time of the chemical raw materials, and will block when the temperature of the chemical raw materials reaches a certain temperature. The discharge pipe makes the foam shape unstable after the chemical raw materials are foamed, and the cells are large and rough, which affects the product performance. Contents of...
