Abstract

The present invention provides a powder-dispensing device that is capable to reduce the amount of powder flying away and preventing the powder from being dispensed in a lump. The powder-dispensing device is constructed so that a powder-dispensing roller 18 arranged under a powder storage tank 12 is rotated to cause the powder 10 attached to the powder-dispensing roller 18 to be dispensed onto a powder coated article 30 passing under the powder-dispensing roller 18. Space isolating rollers 32, 34 that are adjacent to the powder-dispensing roller 18 are arranged in the moving direction of the powder coated article 30 and located at the upstream and downstream sides of the powder-dispensing roller 18, respectively, so as to form an isolated space 36 for powder-dispensing directly below the powder-dispensing roller 18.

Description

technical field

[0001] The present invention relates to a powder dispersing device, in particular to a powder dispersing device for dispersing powder on the surface of a plastic film or a rubber sheet, etc. Adhesion that occurs between films or rubber sheets and is used to improve the slipperiness required in subsequent processes. Background technique

[0002] Rolled thin laminates, plastic films or rubber sheets, etc., if left as they are without any treatment, tend to stick to each other, thereby causing inconvenience to subsequent processes such as printing. In order to avoid this problem, the general practice is to spread fine powder on the surface of these materials when rolling up plastic films or rubber sheets so as to avoid the occurrence of adhesion. However, a powder dispersing device commonly used in the prior art is equipped with a rotating roller at the lower opening of the powder storage tank storing the powder to be dispersed. The powder in the powder storag...

Embodiment Construction

[0012] Hereinafter, specific embodiments of the powder dispersion device of the present invention will be described in detail with reference to the drawings.

[0013] Figure 1 ~ Figure 2 It is a sectional view and an end view of the powder dispersion device according to the first embodiment of the present invention. As shown in the figure, the powder dispersing device of this embodiment has a powder storage tank 12 capable of storing powder 10 such as starch and dispersing the stored powder 10 from the lower part thereof. More specifically, the inside of the powder storage tank 12 is formed with a receiving space 14 with a rectangular cross-section, and a cover 16 is provided on the top thereof so as to prevent the placed powder 10 from flying outside. In addition, a spreading roller 18 having a diameter smaller than the width of the storage space 14 is horizontally provided at the lower rectangular opening of the storage tank 12 so that the lower half thereof is exposed.
