JPH0342062A - Receiving method for powder in injector for spreading powder and controlling method for injected amount of powder - Google Patents

Abstract

PURPOSE:To inject large amounts of powder from an injection port communicated with the inside of a gutter by receiving powder passed through an air-feed pipe together with air to the inside of a powder receiving gutter. CONSTITUTION:An injector 2 of powder is provided to a prescribed position of an air-feed pipe 1 for sending powder by air. A powder receiving gutter 17 described hereunder is projected to the inside of the air-feed pipe 1 of the injector 2. This gutter 17 is communicated with the injection port 13 of the injector 2 and nearly formed into a gutter-shape. Powder passed through the pipe 1 is received to the inside of the gutter 17 together with air. Large amounts of powder are injected through the injection port 13 communicated with the inside of the gutter 17. Further the received amount of powder can be adjusted by turning the gutter 17 at the proper amount not less than the intermediate amount of the gutter. As a result, large amounts of powder are spread regardless of humidity of the atmosphere. Further, the spread amount of powder is freely controlled. Furthermore, the structure is made simple and a trouble is not caused.

Description

[Detailed description of the invention] (Industrial application field) This invention is currently a film that easily adheres to each other.

The present invention relates to a method for efficiently scattering powder, such as starch or corn powder, on the surface of a film, such as a vinyl film, in order to prevent the films from adhering to each other and improve workability.

(Prior art) Conventionally, powder was sprinkled directly onto the surface of the film to be spread, or powder was indirectly spread through a special blower for spreading, or an appropriate amount of powder was continuously inserted into the suction side of a blower. There was a method of blowing air into the air pipe and spraying it from an injection port suitably drilled in the air pipe.

(Problem to be solved by the invention) One of the traditional methods is the direct furikake method.

Apart from the method of dispersing only through a blower, there is a method in which powder is blown into a blower pipe through a blower and then sprayed from a powder injection port disposed at a predetermined position in the pipe. However, the amount of powder emitted cannot be adjusted, the source of the air pipe and the amount of powder sprayed from the injection port of the terminal are different, and it is difficult to spray when the humidity is high. , there is a problem that the powder stops spewing out.

(Means for solving the problem) In order to solve this problem, the powder injection device is provided with a valve that can be operated from the outside and a powder receiving amount in the air pipe.

(Function) A large amount of powder is received by the wind through the powder receiving volume, and the amount of powder to be sprayed is controlled by a valve.

(Example) Embodiments of the invention will be described below based on the drawings.

Fifth. FIG. 6 shows a conventional powder spreading state in which powder is spread on a film surface, and FIG. 5 shows a vertical method, and FIG. 6 shows a horizontal method. In both figures, a film (7) to which powder (8) is attached (for example, thickness 0°05-0.1, width 2
m to 6 m or more) is unrolled and moved directly or via an appropriately structured roller (9) and a drive device from an appropriately wound original fabric (20).

On both sides of the unraveled film (7) at a suitable predetermined position, a predetermined dimension from the film surface, for example 10 to 30 cm
Powder injection port (6), for example, diameter 6, on the film side
A powder blowing tube (1) having a diameter of 6α, for example, is installed, and the end of this tube is connected to a powder blowing device consisting of an annular blower (4) and a powder feeding device (5). There is. The powder blown by the blower is dispersed from the injection port (6) provided in the blowing pipe (1) and adheres to the surface of the film.

The powder dispersed in this way has the disadvantage that the amount of ejection is different between the source and the end of the air pipe (1), and this can be countered by changing the diameter of the injection port or by changing the dimensions of the perforation. There is. Additionally, when the humidity in the air increases, the powder becomes wet and the amount of spray from the nozzle becomes extremely low.
It was used as "something like this."

(First Example) This relates to the first invention, and includes a bright line hole (lO
) to which the injection device (2) shown in FIGS. 1, 2, and 3 is screwed.
