Power assembly of automatic glue spreaders

Abstract

The invention provides a power assembly of automatic glue spreaders, which belongs to the technical field of spreading glue and solves the problems that the prior glue spreading technique realized by the mechanical power of the prior glue spreader is not good for accurate control and continuous operation. The power assembly of automatic glue spreaders comprises a compressed air source, a control system and a transfer passage which is connected with the compressed air source, wherein the transfer passage comprises a transfer pipeline (1) and a transfer pipeline (2) which are respectively used for transferring power airflows for regulating glue injection positions and injection glue; after being connected together, the air inlet ends of the transfer pipeline (1) and the transfer pipeline (2) are connected with an air outlet of the compressed air source; and the control system is used for controlling the transfer conditions of the power airflows in the transfer pipeline (1) and the transfer pipeline (2). The power assembly of automatic glue spreaders uses compressed air as power for replacing the mechanical power; moreover, a user finely regulates glue flow quantity, flow speed, spreading positions, and the like by various controllers and knobs, therefore, uniform spreading and wide application range are achieved.

Description

technical field [0001] The invention belongs to the technical field of gluing, and relates to a power assembly of an automatic gluing machine. Background technique [0002] In some processing fields, gluing is an essential processing procedure, and the fluid gel-like material is applied to the joint surface of the workpiece to achieve the effect of sealing and waterproofing and increasing the joint strength. [0003] At present, the gluing process in many fields adopts manual operation. Because it is manual operation, the operating level and experience of the operator directly affect the effect of applying glue. When applying glue, there are the following problems: it is difficult to control the amount of glue applied: if the amount of glue is applied too much, the glue will overflow, which will not only waste glue but also pollute the surface of the product, resulting in unqualified appearance of the product; too little application can not guarantee the sealing performance...

Because it is manual operation, the operator's operation level and experience directly affect the effect of applying glue

When applying glue, there are the following problems: it is difficult to control the amount of glue applied: if the amount of glue is applied too much, the glue will overflow, which will not only waste glue but also pollute the surface of the product, resulting in unqualified appearance of the product; too little application can not guarantee the sealing performance of the product

The application position is difficult to grasp, which will affect the firmness and sealing of the workpiece connection

[0004] For this reason, many gluing (or dispensing) devices have appeared on the market now, and some of them use mechanical power to realize gluing. Due to the rough control of mechanical power, the disadvantage is that the size of the glue flow is not easy to control uniformly, and the mechanical power is released. It is easy to have a hysteresis process in the end, and the flow cannot be cut off immediately, which is not conducive to precise control and continuous operation, and is easy to cause waste
