Description
Technical Field
The invention relates to the field of printing, in particular to a corner printing method for a special-shaped bottle.
Background
The silk screen printing refers to that a silk screen is used as a plate base, and a silk screen printing plate with pictures and texts is manufactured by a photosensitive plate making method. When printing, ink is poured into one end of the screen printing plate, a scraper plate is used for applying a certain pressure to the ink position on the screen printing plate, meanwhile, the scraper plate moves towards the other end of the screen printing plate at a constant speed, and the ink is extruded onto a printing stock from meshes of the image-text part by the scraper plate in the moving process. The requirement of using a bottle as a printing stock is increasing day by day, but the bottle as the printing stock is not necessarily regular cylindrical, and for a special-shaped bottle with a corner or a bottle body with a radian, the traditional silk-screen process is obviously not enough, and the traditional silk-screen process generally adopts the height adjustment of a printing knife for printing the corner of the bottle body, but because the curvature of the corner of the bottle body is different from the curvature of the plane of the bottle body, namely in the silk-screen process, the printing speed of the corner is inconsistent with the printing speed of the bottle body, the problem of unclear printing or ink overflow at the corner can be caused.
Disclosure of Invention
In order to solve the technical problem that the corner of the bottle body printed by the traditional silk-screen printing process is unclear or ink overflows at present, the invention provides a corner printing method of a special-shaped bottle, which comprises a positioning step and a silk-screen printing step which are sequentially carried out,
the positioning step comprises: the clamping part of the screen printing machine has a stabilizing effect on a bottle to be printed, the fixing rod at the front end of the clamping part clamps the bottle mouth position of the bottle, the rear end of the clamping part stabilizes the bottom of the bottle, the clamping part can ascend or descend along with the screen printing process, and the fixing rod of the clamping part drives the bottle body to rotate;
the silk-screen printing step comprises surface silk-screen printing and corner silk-screen printing,
and (3) surface silk-screen printing: pressing down the printing cutter component, starting a screen printing plate system, synchronously starting a clamping part, enabling the clamping part to float up and down in the silk-screen printing process, keeping a certain distance between the surface of the bottle body to be printed and a screen plate, simultaneously driving the bottle body to rotate by the clamping part, enabling the printing cutter component to swing left and right, keeping the cutter point of the printing cutter in contact with the highest point of the bottle body to be printed, and extruding ink on the bottle body to be printed by the printing cutter through the screen plate to form patterns and characters;
and (3) corner silk-screen printing: connecting two adjacent surface silkscreens by corner silkscreens, determining height compensation parameters and speed coefficients, driving the bottle body to continue rotating by the clamping part after the previous surface silkscreen is finished, compensating the height of the printing knife upwards or downwards at the corner according to the radian of the corner, adjusting the speed change of the bottle body rotating according to the set speed coefficient, extruding ink onto the bottle body uniformly by the printing knife through a screen printing plate, performing the surface silkscreen again after the corner silkscreen printing is finished, and repeating the steps until the silkscreen printing is finished.
The surface silk screen printing is the arc surface silk screen printing, the main height compensation of the printing cutter is required to be determined according to the curvature radius of the arc surface, the pressing distance of the printing cutter component is adjusted according to the main height compensation, the clamping part floats up and down, the surface of the bottle body to be printed is kept at a certain distance from the screen plate, meanwhile, the bottle body is driven to rotate according to the clamping part, and the printing cutter extrudes printing ink to the bottle body to be printed through the screen plate to form patterns and characters.
The bottle body is shaped like a special-shaped bottle with a corner.
The special-shaped bottle is a bottle with a round-corner rectangle or an eight-arc cross section.
When the corner is printed, the height of the corner can be adjusted through height compensation, the contact pressure between the printing knife shaft and the printing surface can be adjusted, the height increased by the printing knife is height compensation, the range of the height compensation is +/-5 mm, and the range of the main height compensation is +/-5 mm.
The speed of the printed article is different on different radians or planes, the speed of the printing plane or the radian is changed by arranging a speed system, the attachment amount of the used printing ink on the object is different, the ratio of the change value of the speed of the printing arc surface to the speed of the printing plane is a speed coefficient, the speed coefficient is 0.1-5%, and the main speed coefficient is 0.1-5%.
Advantageous effects
According to the invention, the height compensation and the speed coefficient are arranged at the corner of the printing bottle body, the printing knife adjusts the ascending or descending distance according to the radian of the corner, and the rotating speed of the bottle is adjusted according to the radian of the corner, so that the rotating speed of the bottle body is matched with the silk-screen printing speed of the printing knife, and the effect of solving the problems of unclear corner silk-screen printing or ink overflow is achieved.
Detailed Description
The present invention will be further described with reference to the following examples.
A method for printing the corner of shaped bottle includes such steps as sequentially locating the bottle to be silk-screened on feeding conveyer belt, putting the bottle in the clamping position, clamping the bottle mouth by the fixing rod at front end of the clamping position, stabilizing the bottom by the fixing rod at back end, driving the fixing rod to rotate by the clamping position to drive the bottle body to rotate,
the silk screen printing step includes face silk screen printing and corner silk screen printing that carry out in proper order, and during face silk screen printing, seal sword uniform motion, the dead lever is rotatory simultaneously and is driven the body rotatory, carries out interface silk screen printing after rotatory to the corner, carries out face silk screen printing again after accomplishing corner silk screen printing, repeats above step until the silk screen printing is accomplished.
Example 1
Round corner rectangle: the height compensation is 3mm, and the speed coefficient is 0.1%;
