Abstract
The utility model discloses an etching machine, and belongs to the technical field of the etching equipment. The etching machine comprises a roller conveying device which is arranged in a box body; the left side and the right side of the box body are both provided with a plurality of liquid feeding ports; each liquid feeding port is communicated with two spray pipes which are arranged vertically; either spray pipe is provided with a plurality of nozzles; the roller conveying device is arranged between the nozzles of the upper spray pipe and the lower spray pipe; and spray pipes which are communicated with the left liquid feeding port and spray pipes which are communicated with the right liquid feeding port are arranged at intervals. The utility model has the advantages of uniform etching and high production efficiency.
Description
Technical field
The utility model discloses a kind of etching machine, belong to the etching machines technical field.
Background technology
The feed liquor mode of existing etching machine is non-convection type, and as shown in Figure 1, etching solution enters each self-corresponding shower 2 by several fluid inlets 1 that are positioned at homonymy, by several nozzles 3 that are installed on each shower 2 etching solution atomizing back is sprayed again.Each fluid inlet 1 is communicated with two showers 2 that distribute up and down.Between the nozzle 3 of each upper and lower shower 2 roller conveying device 4 is installed.Metal sheet 5 is entered by the front side of roller conveying device 4, and rear side spreads out of.In the course of conveying, etching solution to spraying on the metal sheet 5, carries out etching to metal sheet 5 from upper and lower after nozzle 3 atomizings of each upper and lower shower 2.The metal sheet 5 that comes out by this non-convection type etching machine etching, have the uneven problem of etching, and this problem is caused by following reason mainly: nozzle 3 pressure that are positioned at shower 2 liquid feeding ends are big, and nozzle 3 pressure that are positioned at shower 2 ends are little, thereby cause etching inhomogeneous, influence product performance.
The utility model content
In order to address the above problem, the utility model provides a kind of etching uniform etching machine.
To achieve these goals, the technical scheme that the utility model adopted is:
A kind of etching machine, comprise and be installed in the intravital roller conveying device of case, the described casing left and right sides all offers several fluid inlets, each fluid inlet is communicated with two showers that distribute up and down, several nozzles are installed on every shower, roller conveying device and is communicated with each shower and each the shower space arrangement that is communicated with the right side fluid inlet of left side fluid inlet between the nozzle of each upper and lower shower.
As the further setting of such scheme, the spacing distance H of described each shower is 15 centimetres.
On each shower of fluid inlet 7 nozzles are installed on the left of described the connection, on each shower of connection right side fluid inlet 6 nozzles are installed.
After adopting such scheme, the utility model all offers fluid inlet in the casing left and right sides, each shower that is communicated with the left side fluid inlet is arranged with each the shower space that is communicated with the right side fluid inlet, solved one-sided fluid inlet, big because of the nozzle pressure that is positioned at the shower liquid feeding end, as the to be positioned at the shower end little etching problem of non-uniform that produces of nozzle pressure.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Description of drawings
Fig. 1 is the structural representation of the non-convection type etching machine of prior art;
Fig. 2 is the structural representation of the utility model etching machine.
Embodiment
As shown in Figure 2, the utility model etching machine, comprise that the left and right sides all offers the casing 6 of several fluid inlets 8, each fluid inlet 8 is communicated with two showers 9 that distribute up and down, several nozzles 10 are installed on every shower 9, between the nozzle 10 of each upper and lower shower 9 roller conveying device 7 is installed, and is communicated with each shower 9 and each the shower 9 spaces arrangement that is communicated with right side fluid inlet 8 of left side fluid inlet 8.
Each shower 9 that is communicated with left side fluid inlet 8, its nozzle 10 pressure that are positioned at shower 9 liquid feeding ends nozzle 10 pressure big, that be positioned at shower 9 ends are little; Each shower 9 that is communicated with right side fluid inlet 8, its nozzle 10 pressure that are positioned at shower 9 liquid feeding ends nozzle 10 pressure big, that be positioned at shower 9 ends are little.Combination by left and right sides fluid inlet 8 is provided with, and has overcome the shortcoming of one-sided feed liquor, has solved metal sheet 11 etching problem of non-uniform.
More reasonable for the layout that makes each shower 9 and nozzle 10, so that further improve etch effect and production efficiency, the spacing distance H of each shower 9 is 15 centimetres; On each shower 9 of fluid inlet 87 nozzles 10 are installed on the left of being communicated with, on each shower 9 of connection right side fluid inlet 86 nozzles 10 are installed.
The foregoing description only is used to the inventive concept of the present utility model of explaining, but not to the qualification of the utility model rights protection, allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should fall into protection domain of the present utility model.
