Abstract
A liquid coating technology includes such steps as spraying a thicker liquid layer on the surface of the object to be coated, fixing the object to the center of a controllable rotary platform, high-speed rotating for centrifugally removing excessive liquid to form a uniform coated film layer. Said centrifugal coating machine is composed of machine frame, rotary platform, controllable motor, at least 3 locating cylinders with locating head on said platform for fixing said object to be coated onto platform, and a variable-frequency speed regulator.
Description
Technical field
What the present invention relates to is a kind of special coating process and special-purpose centrifugal plated film machinery that sprays the last layer liquid film on a planar object, belongs to the coating process and the special-purpose plated film machinery of the bad object of a kind of surperficial seepage of water.
Background technology
In the prior art, the coating process of the bad object of surperficial seepage of water often utilizes a kind of airless spray unit to carry out the airless spraying technology of liquid spray.This airless spray unit is made up of the transmission system of fluid reservoir, infusion pump, flowmeter, pipeline, valve, frame, shower nozzle and adjustable-speed; Plated body is fixed on conveying roller upper edge directions X and travels forward, and its movement velocity is stepless adjustable by RHVC; Shower nozzle is installed in the reciprocating motion of making the Y direction on the frame, and the speed of swing is also stepless adjustable by RHVC; Plated film work shower nozzle is done to adjust up and down on the Z direction, to regulate the distance on shower nozzle and plated body surface, reach best spraying effect, adjust the motion of X, Y two directions, make the spraying effect of plated body reach the effect that looks like the television set electron scanning, guarantee the uniformity of plated film layer in spraying process, avoid coating liquid to pile up undue overlapping of body surface.Though the cost of above-mentioned coating process plated film is lower, technology is simple relatively, and the quality of plated film also is not so good as people's will, and the surface coating layer thickness of plated body and the uniformity of concentration are relatively poor, are difficult to satisfy the plated film product needed that some have required precision.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned existence, and provide a kind of and can improve the liquid coating quality, satisfy the liquid coating process and the centrifugal coating machine of plated film required precision.This liquid coating process, it is to form thicker plated film liquid layer by airless spraying technology on the plated body surface earlier, again with the plated body fixed placement at a controlled rotary centrifuge workbench center, and rotation thereupon, the coating liquid unnecessary on following plated body surface of action of centrifugal force forms uniform plated film layer equably to shedding away on the plated body surface all around.
A kind of centrifugal coating machine that is exclusively used in the aforesaid liquid coating process, it includes a frame, one rotatable workbench is installed above the frame, the rotating shaft center of this workbench links to each other with a controlled motor, outer on workbench is evenly equipped with three positional cylinders at least, and its front end is connected with the location working head that can clamp plated body.
Described motor is fixed on the frame and by a variable-frequency governor and links to each other with external power supply, and the output shaft of motor links by the rotary middle spindle of shaft coupling and workbench.
The invention belongs to a kind of improvement to existing liquid coating process, it combines airless spraying with rotating centrifugal two covering devices and technology, it is convenient, controlled, simple and easy to do to have whole technological operation, the plated film qualification rate of product can be present more than 95% by originally bringing up on a small quantity, the characteristics such as coating quality on plated body surface have been improved greatly, for the production of industrialization plated film provides necessary condition.
Description of drawings
Fig. 1 is a centrifugal coating machine structural representation of the present invention.
The specific embodiment
The present invention will be described in detail below in conjunction with drawings and Examples: the present invention mainly finishes by following two procedures, and first procedure is: form a uniform plated film liquid layer by airless spray unit on the surface of plated body; Second operation work is: through rotating centrifugal, the unnecessary coating liquid in plated body surface is shed away equably, form the plated film layer that liquid level was evenly distributed, did not have mottling, transparency height, boundless effect phenomenon on the plated body surface, and described thicknesses of layers can be adjusted according to rotary speed, the coating liquid concentration of plated film layer also can be adjusted according to rotary speed, makes it to reach fully the requirement of technological requirement and industrialization production.
Liquid coating process of the present invention, it is to form thicker plated film liquid layer by airless spraying technology on the plated body surface earlier, again with the plated body fixed placement at a controlled rotary centrifuge workbench center, and rotation thereupon, the coating liquid unnecessary on following plated body surface of action of centrifugal force forms uniform plated film layer equably to shedding away on the plated body surface all around.
Figure 1 shows that a kind of centrifugal coating machine that is exclusively used in the aforesaid liquid coating process, it includes a frame 1, one rotatable workbench 2 is installed above the frame 1, the rotating shaft center of this workbench 2 links to each other with a controlled motor 3, described motor is fixed on the frame and by a variable-frequency governor and links to each other with external power supply, and the output shaft of motor links by the rotary middle spindle of shaft coupling and workbench; Outer on workbench 2 is evenly equipped with three positional cylinders 4 at least, and its front end is connected with the location working head 5 that can clamp plated body.
Specifically when operation, should be according to as much as possible the center of gravity of plated body being placed on the central point of rotary working platform by the shape of poisonous substance, in order to avoid in the rotating centrifugal operation, form excessive centrifugal force, influence the uniformity of rete, with guarantee coating liquid in the rotating centrifugal operating process along center of gravity to around do radially to leave equably, also to adjust the position of positioning cylinder according to the shape of plated body, guarantee that plated body is securely fixed on the workbench, plated body takes place when preventing the rotating centrifugal operation shed case accident, the fixing working head of cylinder should be acute angle, firm plastic object, the plane that can not use the plane or have a relative length is blocked, to avoid coating liquid in operation packing phenomenon to be arranged, cause the inhomogeneous of rete in limit portion.The speed of described centrifugal rotation realizes by variable-frequency governor control motor.In specific implementation process, can select glass as plated body, form even plated film layer at described glass surface.
