Abstract
The invention discloses a mechanism for adjusting film flatness. The mechanism comprises two adjusting units, wherein each adjusting unit comprises a clamping body, a roller support frame, a fixing base and a screw rod; the clamping body is connected with the screw rod; a roller supporting seat is connected with a roller end; and the screw rod is connected with the roller supporting seat. Through rotation, the roller supporting seat on the screw rod moves up and down, so that the contact surface between the roller and the film is adjusted; and moreover, a fine tuning bolt is adjusted, so that the contact surface of the roller and the film moves back and forth, and the tightness state of the film plane is adjusted. The roller is adjusted to move up and down and back and forth through the fine tuning bolt and the screw rod, and the film flatness is adjusted by changing the contact surface between the roller and the film. The mechanism is easy to operate and only needs to be adjusted according to the basic conditions of the film plane during compounding, and the phenomenon that the compounded film generates bubbles or wrinkles because the tightness at two ends of the film is inconsistent is avoided.
Description
Technical field
The present invention relates to a kind of governor motion, specifically refer to a kind of for the mechanism that regulates the film flatness.
Background technology
The film compounding machine must guarantee that the compound film of wanting guarantees its flatness before recombination process, avoid fold occurring or produce bubble between compound tense layer and layer, thereby cause producing defect ware or waste product laminated film.For reducing to produce the possibility of fold, normally consider in the material of cylinder or vpg connection in the prior art, rotate roller as two of collapser upper end and be generally the aluminium roller, aluminium has good heat conductivity, so the aluminium roller can not produce too many problem on this link.
Nonetheless, influence after the eliminating temperature is compound to film, in the compound flow process of whole film, in the transmission way before film is compound, may exist the film two ends the inconsistent situation of degree of tightness to occur, thereby cause fold occurring between compound tense thin layer and the layer, uneven thickness appears in final finished film, and the optics of film, mechanical property reduce.
Summary of the invention
The present invention a kind ofly solves the problem that compound tense tracting film two ends degree of tightness differs for the mechanism that regulates the film flatness by arranging, to reach by regulating the purpose of cylinder gradient smooth corrugationless compounding machine when making the compound transmission of film.
Purpose of the present invention reaches by the following technical programs:
The present invention is a kind of for the mechanism that regulates the film flatness, comprise two adjustment units, described adjustment unit, comprise screens body, roller cage, fixed pedestal and screw rod, described screens body is connected with screw rod, described idler seat and cylinder termination join, and described screw rod is connected with the cylinder supporting seat, can realize the function of cylinder supporting seat upper and lower displacement by rotary screw; Described screens physical efficiency limits it and continues motion after the roller cage distance certain to top offset, avoided faulty operation to make that compound film is impaired.
Further, described fixed pedestal is provided with endoporus, and screw rod passes endoporus, and the external diameter of screw rod is less than the internal diameter of endoporus.Fixed pedestal can make screw rod fix, and keeps its original place to rotate to be the power that roller cage provides upper and lower displacement.
Further, screw rod is rotatable and upper and lower displacement do not take place.By original place rotation, make cylinder supporting seat upper and lower displacement on the screw rod, thus the gradient of regulating the contact-making surface of cylinder and film.
Further, described supporting seat is provided with trimming bolt.Regulate trimming bolt and can make cylinder and film move forward and backward, thereby regulate the degree of tightness state of thin film planar.
Further, the installation and removal maintenance is convenient to for removably connecting in described cylinder supporting seat and cylinder termination.
The present invention is made up of two adjustment units, places the both sides of cylinder respectively.
The present invention compared with prior art, have following advantage and a beneficial effect:
1 the present invention is a kind of to be regulated cylinder by trimming bolt and screw rod and moves forward and backward up and down for the mechanism that regulates the film flatness, the flatness of regulating film by the contact-making surface that changes cylinder and film.The present invention is simple to operate, only needs regulate according to the basal conditions of compound tense thin film planar, has avoided causing because film two ends degree of tightness is inconsistent compound rear film bubble or has produced fold.
2 the present invention are a kind of for the mechanism that regulates the film flatness, and the installation and removal maintenance is convenient to for removably connecting in cylinder supporting seat and cylinder termination.
3 the present invention are a kind of for the mechanism that regulates the film flatness, and are detachable, easy for installation between each parts, applicable to the supporting use of plurality of devices.
Description of drawings
Fig. 1 is structural representation of the present invention.
The specific embodiment
As shown in Figure 1, when the transmission of film compound tense, when finding the situation of the tight and right-hand member pine of film left end, by fixedly connected screw rod 4 on the rotation right-hand member fixed pedestal 3, cylinder supporting seat 2 upwards is subjected to displacement, drive roller shifting, finely tune the trimming bolt 5 on the cylinder supporting seat 2 simultaneously, make the cylinder right-hand member move inward, thereby make right-hand member tighten, reach required effect.
As shown in Figure 1, when the compound transmission of film, when finding the situation of the tight and left end pine of film right-hand member, by fixedly connected screw rod 4 on the rotation left end fixed pedestal 3, cylinder supporting seat 2 upwards is subjected to displacement, drive roller shifting, finely tune the trimming bolt 5 on the cylinder supporting seat 2 simultaneously, make the cylinder left end move inward, thereby make left end tighten, reach required effect.
As shown in Figure 1, screw rod 4 is rotatable and upper and lower displacement do not take place.By original place rotation, make cylinder supporting seat 2 upper and lower displacements on the screw rod 4, thus the gradient of regulating the contact-making surface of cylinder and film.
As shown in Figure 1, the difference of present embodiment and embodiment 4 is that screw rod 4 is connected with the mode of cylinder supporting seat 2 by the screw thread coupling.
In sum, namely can better realize the present invention.
