Abstract
The utility model provides a scraper pressure adjusting device based on a servo motor, which comprises a scraper frame, a pressure sensor arranged in the scraper and a vertically arranged screw rod nut pair. The scraper frame is connected onto nuts of the screw rod nut pair, and a screw rod is positioned axially and provided with a first gear. The adjusting device is further provided with the servo motor and a transmission mechanism driven by the servo motor. The transmission mechanism is provided with a second gear, and the second gear is meshed with the first gear and outputs driving force to the first gear. The pressure sensor is connected with a scraper pressure adjusting controller, and the scraper pressure adjusting controller is connected with a servo controller of the servo motor. By means of the technical scheme, the scraper pressure adjusting device based on the servo motor can set scrapper pressure in remote mode, detect pressure through the pressure sensor, adjust scrapper pressure through the servo motor, control scrapper pressure more accurately and improve quality of flat screen printing.
Description
Technical field
The utility model relates to PLATE SCREAM PRINTING machinery field, relates in particular to the scraper pressure adjusting device based on servomotor.
Background technology
In PLATE SCREAM PRINTING, the pressure of scraper is regulated accurately significant to full, the coloured light of meticulous, the color of flower type.In the past, in PLATE SCREAM PRINTING, regulated scraper to transporting the pressure of belt with the height that transports belt through manual rotary screw adjustment scraper.This adjustment structure; The randomness that build-up of pressure is regulated is big, repeatability is poor, the adjustment time is long; Easily because of adjusting pressure causes the product quality difference of a large amount of defective works, repeatedly production big, the difficulty production technology standard formulation is big, factory also need train personnel for a long time in stamp production.
Utility model patent CN201626165U improves this structure, has realized the Position Control of scraper, and the principle of this scheme foundation is that the pressure of scraper is proportional with the positional value that presses down.But this position and pressure is a kind of non-linear relation in essence, so this scheme and be the accurate pressure control method.
Summary of the invention
The utility model technical problem to be solved provides a kind of scraper pressure adjusting device based on servomotor, need not manual intervention and promptly can carry out the mechanization adjustment of scraper and be convenient to automation control.For this reason; The utility model adopts following technical scheme: it comprises doctor blade holder, is installed on the pressure sensor on the scraper, vertically disposed feed screw nut pays; Said doctor blade holder is connected on the nut that the feed screw nut pays; Said screw mandrel is axially located and is being with first gear, said adjusting device also to be provided with servomotor and by the transmission mechanism of driven by servomotor, said transmission mechanism has second gear to the first gear output drive strength with said first gears engaged; Said pressure sensor links to each other with scraper pressure adjustment controller, and the servo controller of said scraper pressure adjustment controller and servomotor is connected.Owing to adopt the technical scheme of the utility model, can be through the long-range scraper pressure that is provided with, through the pressure sensor detected pressures, through servomotor adjustment scraper pressure, can more high-precision control scraper pressure, improve the quality of PLATE SCREAM PRINTING.
Description of drawings
Fig. 1 is the sketch map of the mechanical part of the embodiment that the utility model provided.

The specific embodiment
With reference to accompanying drawing 1.The utility model comprises that doctor blade holder 4, vertically disposed feed screw nut pay; Said doctor blade holder is connected on the nut 6 that the feed screw nut pays; The screw mandrel 7 that the feed screw nut pays is axially located and is being with first gear 1; The transmission mechanism that said adjusting device also is provided with servomotor 2 and is driven by servomotor 2, said transmission mechanism have second gear 3 to the first gear output drive strength with 1 engagement of said first gear.Said transmission device comprises that reducing gear 21, bevel gear pay 22, drive link 23, and said second gear 3 is installed on the drive link 23.Drawing reference numeral 5 is for being installed in the scraper on the doctor blade holder.
Said adjusting device also is provided with the pressure sensor 9 that is installed on the scraper 5, and said pressure sensor 9 links to each other with scraper pressure adjustment controller, and the servo controller of said scraper pressure adjustment controller and servomotor is connected.
With reference to accompanying drawing 2.The utility model is provided with servo controller, said servo controller control servomotor 2; Said adjusting device also is provided with position coder; Said position coder has data communication with servo controller and is connected; Said servo controller also is provided with scraper and adjusts the control interface device automatically, and said scraper is adjusted the control interface device automatically and had data communication with servo controller and be connected.It is an arithmetic unit that has display unit and human-computer interaction function that scraper is adjusted the control interface device automatically.
Servo controller control servomotor 2 descends scraper 5; Servomotor 2 is being with said position coder record position; When the scraper lower surface just contacts when transporting belt; Position coder can be pointed out the position of this moment; Position data is sent to servo controller, and servo controller is sent to scraper with position data and adjusts the control interface device automatically, and scraper is adjusted the control interface device automatically can the record position data and as original position.
Like needs adjustment scraper pressure; The host computer setting will be provided with parameter through the RS484 bus and deliver to scraper pressure adjustment controller; Control servo controller then doctor position is carried out coarse adjustment; Finely tune through the detected actual pressure of pressure sensor, when technology controlling and process personnel just can write down different production status scraper add accurate pressure value, can make corresponding technological standards.
Said scraper pressure adjustment controller can adopt single-chip microcomputer.Adjustment algorithm can adopt the proportional integral algorithm, can realize the quick-adjustsing while floating of pressure adjustment like this.
