Description

Tool of excessive black protection of spraying

Technical Field

The utility model belongs to the technical field of the spraying equipment, concretely relates to tool of excessive black protection of spraying.

Background

The present intelligent wearing industry rises, the manufacture of the watch cover and the dial plate needs to be completed by using a spraying process, an upper clamping plate and a lower clamping plate are usually adopted to clamp a target spraying part during spraying, the part needing spraying is exposed, the spraying process can cause ink overflow pollution to other non-spraying areas in different degrees, secondary wiping treatment is needed, and the spraying in the present industry exists. The conventional timely scheme for reducing ink overflow pollution is that parts such as sponge absorbing ink are added in an ink overflow area to absorb ink overflow, but the sponge absorbing ink overflow needs to be replaced and cleaned, and a certain trace is left at the position where the sponge absorbing ink overflow, so that the spraying efficiency is reduced, and the precision is not high. Or the adhesive tape is adhered to the surface of the sprayed workpiece, the surface which is not sprayed is shielded, and the surface which is not sprayed is prevented from being polluted, however, the adhesive tape is usually discarded after being used once, and the adhesive tape is a consumable material, so that the production cost is increased.

Disclosure of Invention

The utility model aims at having the above-mentioned problem to current technique, provided a tool that excessive china ink of spraying protected, the utility model aims to solve the technical problem that: how to prevent the condition of ink overflow during spraying.

The purpose of the utility model can be realized by the following technical proposal:

a jig for protecting ink overflow during spraying comprises an upper clamp plate and a lower clamp plate and is characterized in that a flexible wrapping piece made of flexible materials is clamped between the upper clamp plate and the lower clamp plate, a first spraying hole penetrating through the top surface of the flexible wrapping piece is formed in the flexible wrapping piece, the first spraying hole is a step hole, a second spraying hole communicated with the first spraying hole is formed in the upper clamp plate, and the aperture of the second spraying hole is larger than or equal to that of the first spraying hole.

The part that needs to carry out the spraying is placed and is leaned on with the step face in spraying hole one in flexible parcel piece, the size of part slightly is greater than the internal diameter in spraying hole one and makes flexible parcel piece produce slight deformation and wrap up the part edge, the part that spraying hole one will need on the part exposes, flexible parcel piece is placed between lower plate and upper plate, with spraying hole two alignment spraying hole one, upper plate and lower plate hold flexible parcel after, the upper plate pushes down flexible parcel piece fixedly, can also prevent that the spraying from sending out coating and overflowing into between lower plate and the flexible parcel piece, reduce flexible parcel piece and contact coating, the life of extension flexible parcel piece, and prevent the condition of the excessive black of spraying.

In the above-mentioned spraying ink overflow protection jig, a connecting structure for connecting the upper clamping plate and the lower clamping plate is arranged between the upper clamping plate and the lower clamping plate.
