Abstract

The utility model relates to the screen printing machine technical field, especially for an automatic positioning device on the silk screen printing machine; the silk screen printing machine is installed with a color code sensor and a supporting arm, and a cross bar is connected and fixed with two supporting arms which are matched through a sliding chute and a sliding rail and fixed on the frame; moreover, the supporting arm can slide right and left; a servo-motor drives the cross bar and the supporting arm to slide right and left through a screw rod and a nut, and the color code sensor measures the offset of the pattern on the printing paper; moreover, the offset is transmitted to the controller of the servo-motor, and the controller controls the servo-motor to drive the supporting arm to slide corresponding offset; the utility model is provided with a simple structure and realizes automatic positioning and regulation to the screen block, and the printing precision and the operational efficiency are greatly enhanced.

Description

Automatic contraposition device on a kind of screen process press
Technical field:
The utility model relates to the screen process press technical field, refers in particular to the automatic contraposition device on a kind of screen process press.
Background technology:
Screen process press need print through multiple chromatography contraposition when the pattern of the two or more colors of printing in process of production, thus require the location between half tone and the stock accurate, otherwise deviation, dislocation will appear in the picture and text that print, and influence printing effect.Usually, screen process press all needed the half tone of back level printing place is regulated and located in when printing, made appointed positions on its accurate corresponding stock.Through after the pattern that comes out of screen painting of level printing place or color printing on predefined position, with the pattern that has printed or color-set synthetic one and designed with patterns, finally be printed as the finished product of standard.
And at present to the adjusting of this kind machine half tone and location all by operation manually, and this position is fixed dead.So not only positioning difficulty is big, the more important thing is the half tone position that regulates, soon with, stretch or the stock that is shifted takes place than large deviation because of the influence that is subjected to tension force and other factors, the printing loss is big, operating efficiency is extremely low; Because each half tone must arrange at least one workman to be responsible for adjusting work, need number of workers many simultaneously, cause the increase of labour cost.
The utility model content:
The purpose of this utility model is to provide automatic contraposition device on a kind of screen process press at the deficiencies in the prior art, and the automatic contraposition device accuracy height on this kind screen process press is simple in structure, has greatly improved the printed matter quality.
For achieving the above object, the utility model is achieved through the following technical solutions: it comprises the half tone installing rack, holds up arm, screw mandrel, servomotor, color mark sensor, cross bar is connected and fixed two and holds up arm, holds up arm to cooperate by the chute slide rail for two and slidably is fixed on the frame; On the described frame servomotor is installed, servomotor is connected with screw mandrel by decelerator, and screw mandrel is provided with and its spiral nut engaged, and nut is fixed on the cross bar; And being fixed in two, holds up on the arm half tone installing rack, the color mark sensor that is connected to the controller of servomotor is installed on the frame of printing machine, the another one characteristics of this structural design are: whole automatic kinematic system is positioned at the top of print station, the arm sling of holding up that is used for fixing half tone is hung on the printing frame, be convenient to operation, installation and maintenance.
The utility model is that color mark sensor is installed on screen process press, this color mark sensor is finished in the feeding process at stock, automatically detect and pick out on the stock position, some colors ground of impression case, and the contrast of the sensed position pre-set with it calculates the difference amount, and this difference amount is sent to the controller of servomotor; Also be provided with two arms of holding up that install and fix the half tone installing rack on the screen process press, cross bar is connected and fixed two and holds up arm, hold up arm to cooperate by the chute slide rail for two and be fixed on the frame, and hold up arm to horizontally slip, the described arm of holding up can also be fixed on the frame by alternate manner slidably; Servomotor also is installed on the frame, servomotor is connected with screw mandrel by decelerator, and this decelerator can be planetary reduction gear, and nut is installed on the screw mandrel, this nut is fixed on the cross bar, and servomotor can drive cross bar and hold up arm to horizontally slip by decelerator, screw mandrel and nut.When skew takes place in the pattern position on stock, the controller of servomotor is then controlled servomotor and is rotated after receiving the detected difference amount of color mark sensor, and drive and to hold up the arm corresponding displacement of sliding, and the half tone that is installed on the half tone installing rack is moved on the preposition, its pattern that prints can just be dropped on the preposition, finish automatic location and adjusting work automatically, need not stop machine in the printing process, also do not need workman's manual operations to regulate, high efficiency, cost of labor is low, the another one characteristics of this structural design are: whole automatic kinematic system is positioned at the top of print station, the arm sling of holding up that is used for fixing half tone is hung on the printing frame, is convenient to operation, installation and maintenance.In sum, the utility model is simple in structure, realizes full-automatic location and adjusting to half tone, operation, install, safeguard simple and convenient, and print definition height, printing efficiency height.
