In order to improve the composite effect of two-sided color printed plastic material, the rate of reducing the number of rejects and seconds, improve the quality of products, reduce the deviation that produces between two color printing films, a more excellent scheme, the number of described set composite is two, is respectively first set composite, second set composite, first set composite cooperates with the first color printing film conveying mechanism, and second set composite cooperates with the second color printing film conveying mechanism.That is to say that two-sided plastic compounding machine is arranged by the order of production procedure, comprises plastic foil unreeling structure, the first color printing film conveying mechanism, first set composite, the second color printing film conveying mechanism, second set composite, deviation correction mechanism, rolling-up mechanism successively.Like this, it is compound that the recombination process of two-sided color printed plastic material is become secondary, by the first color printing film conveying mechanism, first set composite that first face and the first color printing film of plastics is compound earlier.Then, by the second color printing film conveying mechanism, second set composite that second face and the second color printing film of plastics is compound again.This two-sided plastic compounding machine can cooperate above-mentioned method for correcting error preferably, its benefit is: 1) with traditional two sides once simultaneously compound change into twice compound, each compound face, therefore plastics can be than cooling faster, therefore can not be in higher temperature for a long time because of plastics, and cause plastics and color printing film easy deformation and the situation of relative displacement takes place under the pulling force effect, reduce the probability that produces deviation between two color printing films significantly, can reduce the generation of about 30% deviation in the actual production.2) because this structure of employing when therefore rectifying a deviation, can not need the first color printing film conveying mechanism is rectified a deviation with the first for the first time compound color printing film as benchmark, therefore rectify a deviation fast, the step of correction is few, and energy consumption is little.
Described set composite comprises frame, rack-mounted pressure roller, silica gel roller, cold roller, and pressure roller is pressed onto silica gel roller on the cold roller, on the frame of silica gel roller, top, cold roller junction the adhesive extrusion mechanism is installed.
For the tensile force that the color printing film of make carrying is subjected to more steady, thereby further reduce the generation of deviation, the described first color printing film conveying mechanism comprises that first master broadcasts frame, first pair is broadcasted frame, the first servo clamping and conveying device, the first servo clamping and conveying device comprises first nip rolls of first servomotor, two contacts of rolling, one first nip rolls is connected with the first servomotor output shaft, and the signal output part of first servomotor all connects the signal input part of control device.
For the tensile force that the color printing film of make carrying is subjected to more steady, thereby further reduce the generation of deviation, the described second color printing film conveying mechanism comprises that second master broadcasts frame, second pair is broadcasted frame, the second servo clamping and conveying device, the second servo clamping and conveying device comprises second nip rolls of second servomotor, two contacts of rolling, one second nip rolls is connected with the second servomotor output shaft, and the control signal input of second servomotor connects the control signal output of control device.
The color printing film error-correcting method that this two-sided plastic compounding machine adopted may further comprise the steps:
1) two color printing film conveying mechanisms of control device control keep identical normal transfer rate;
2) the colour code checkout gear detects the mark on two-sided two-sided color printed plastic material two sides after compound, and two of will obtain know the mark information and deliver to control device;
3) control device compares above-mentioned two knowledge mark information, and knowing mark information with first is benchmark, relatively knows mark information with respect to the deviate of marking information as the knowledge of benchmark for second;
4) according to above-mentioned deviate, the control of control device output control signal with second know the second corresponding color printing film conveying mechanism of mark information eliminate with the first corresponding color printing film conveying mechanism of first knowledge mark information between deviate, this color printing film conveying mechanism recovers normal transfer rate then.
Step 1 makes that the transfer rate of two color printing film conveying mechanisms is identical, so the position adjustments of color printing film good after, in the problem of not changing color printing film volume, there is not the color printing film because long-time the stretching causes under the situation of moderate finite deformation problem yet, the film that two color printing film conveying mechanisms are sent can guarantee that the color printing film that carries out on two faces of compound resulting two-sided color printed plastic material all is in correct position, and the color printing film is subjected to the external force effect and the degree that stretches can be reduced to minimum degree.
Step 2 colour code checkout gear only detects the two-sided color printed plastic material after compound, just can know whether compound color printing film before should rectify a deviation, and therefore need not the color printing film before compound is detected, and only needs a colour code checkout gear to get final product.
Step 3 control device is known mark information to above-mentioned two and is compared, knowing mark information with first is benchmark, relatively know mark information with respect to the deviation of marking information as the knowledge of benchmark for second, the pairing color printing film of first knowledge mark information conveying mechanism just need not to adjust like this, can know mark information according to second only adjusts second the pairing color printing film of knowledge mark information conveying mechanism with respect to the deviation of marking information as the knowledge of benchmark, the parts that need control have been reduced, simplify step, improved the operating efficiency of control device.For example: second knowledge mark information is slower 0.05 second than first knowledge mark information, and second transmission speed of knowing the pairing color printing film of mark information conveying mechanism is 100 mm/second, and deviation is exactly 5 millimeters so.
In the above-mentioned steps 4, during correction, with the operation of correction speed, correction speed is that normal transfer rate deducts the correction relative velocity to the second color printing film conveying mechanism in the correction time, and the correction relative velocity equals above-mentioned deviate with the product of correction time.That is to say that if deviate is-5 millimeters, the correction time is 1 second, the correction relative velocity is-5 mm/second.The explanation of giving an example below: the transfer rate of two color printing film conveying mechanisms is identical, is 100 mm/second, and second known mark information to know mark information than first slow 5 millimeters, and just deviate is-5 millimeters.So, control device output control signal makes second speed of knowing the color printing film conveying mechanism of mark information correspondence become 105 mm/second, and after one second, speed is got back to 100 mm/second.Like this, in this second, the first color printing film that color printing film conveying mechanism than first knowledge mark information correspondence of the second color printing film that the color printing film conveying mechanism of second knowledge mark information correspondence is sent is sent has been Duoed 5 millimeters, therefore the second color printing film has just been aimed at the first color printing film after one second, has not just had deviation between the color printing film that two color printing film conveying mechanisms are sent.Therefore, this control method can be rectified a deviation in the shortest time, significantly reduces the waste product that produces, and compares with Chinese patent literature CN2475558 technical scheme, can shorten the correction time more than 50%, reduces the waste product more than 50%.
