TW586972B - Adhesive coating using electrostatic charged spraying - Google Patents

Abstract

A method and means to spray hot melt adhesive on a desired non metallic surface by means of using charges adhesive powder sprayed from a powder gun sprayer. The powder is charged in advance with electrostatic charge. A metallic surface is placed behind the surface which the powder has not coat. The metallic surface is connected to high DC voltage and generates an electrostatic field that attracts the sprayed charged particles. As a result of the charged powder accelerating to the metal plates, it hits the non metallic surface standing in the way and coats it with a layer of hot melt adhesive powder. The high speed impact of the powder particles with the surface generate heat that melts the adhesive into active state.

Description of the invention (2) Please refer to the first picture, the spray head (2) is connected to a filling by a pipe (4) A powder tank (1) with an adhesive powder. The powder tank (1) is pressurized by a gas pump (air p u m p) (9) under a high-pressure state. The powder is then pressed out of the powder tank (1) and enters the spray head (2). The spray head (2) is connected to the positive potential of the high-voltage source (3). This voltage causes the powder particles to be charged through the spray head (2) with a positive charge. It is worth noting that the powder may be composed of dry adhesive particles. A surface (5) must have the powder acting on it and be placed under the spray grab. The first metal plate (7) is connected to the positive potential of the high-voltage source (3). The second metal plate (6) is positioned below the surface (5). The second metal plate (6) is connected to the negative potential of the high-voltage source (3). As a result, a strong electrostatic field is formed between the spray head (2) and the second metal plate (6). The powder particles charged in the nozzle of the spray head (2) are accelerated toward the second metal plate (6). Because the surface (5) is between the spray head (2) and the second metal plate (6), when accelerated in an electrostatic field, most of the powder particles will hit the surface (5) . The result of this shock is heat / energy due to the energy released during the collision. This heat melts the adhesive powder particles, so the surface (5) is covered with a layer of adhesive. The second figure describes a synthesis of the method and device described in the first figure. In addition to the second metal plate (6), the metal plates (61), (62), (63) (64) are Around the surface (5). Each of the metal plates (η) ′ ^ 2), (63), (64) is individually connected to a high-voltage electrode to provide a high-voltage potential. Each electrode is connected to a high-voltage distributor (1 0). The high-voltage distributor (10) is

Description of the Invention (3) Selectively connect each metal plate (61), (62), (63), (64) to high voltage at different periods, with different Voltage level. Therefore, the electrostatic field formed between the metal plates (61), (62), (63), (64) and the spray head (2) can use the distributor (voltage generator) < voltage generator >) (10) changes with time and shape. As a result, the acceleration path of each powder particle is accelerated from the nozzle of the spray head (2), and can be guided and controlled at will by the distributor (voltage generator) (丨 〇), and the distribution of (10) can be further advanced Controlled by a microprocessor (14). 'Set (63), in any (data) buy operator to control the computer monitor is to use the board element to be painted in the industry (5) the order of the time and the distribution to the different metal plates (6 丨) The high voltage level of (62) (6 4) is provided as an arithmetic program. On a computer data storage medium, such as a magnetic disk, and read out through the device (12), the data device (12) can The machine is connected to the microprocessor (1 4). The microprocessor (1 4) further uses a control sheet composed of a data entry device, such as a keyboard and a display device, which can be used for measurement (c0 m p u t e r m m n i t〇r). The second figure illustrates another embodiment of the present invention. In this implementation of the surface (5) (which can be made of arbitrary geometry), the board is connected to the -v potential. It is worth noting that the covering surface (5) may be the sole of a shoe. The surface (5) is first coated with a conductive layer. This coating is usually made from a variety of suitable conductive sprayers. The high-voltage source (3) is directly connected to the surface (5) by the V potential, so an electrostatic field is directly formed between the first: m⑺, and the first storage device, a magnetic disk, can be one yuan (16), such as one
