Abstract
The utility model discloses a screen printing plate pretensioner, which includes a power plant, a steel rope, and two fixtures. An outward tension is preset to the screen frame by clamping the relative two sides of the screen frame, when the screen is stretched and fixed, the tension of the screen frame is counteracted with the stress and deformation generated by the tension of the silk screen cloth, and the screen cloth is sufficiently streched to a flat shape in order to ensure the accuracy of printing.
Description
Technical field
The utility model relates to a kind of printing servicing unit, is specifically related to a kind of half tone pretension fixing device.
Technical background
Screen painting is called as omnipotent printing, it can print on various printable fabrics, such as various plastics, textile, materials such as metal, glass, pottery can be applied to commerce, advertising, decoration trade, fine arts industry, building industry, publishing business, dyeing industry, electronics industry etc.In a word, no matter any have object shape, size, thickness, the quality of shape all can carry out screen painting.Screen painting has the advantage of himself uniqueness: small investment, and expense is low, and technology is easily grasped, and is convenient to promote development.The half tone structure generally includes screen frame and screen cloth, after screen cloth carries out stretch-draw, be fixed on the screen frame by variety of ways such as stickups, the co-ordination of screen cloth is made up of polyester or metal wire, for making in the screen painting process, guarantee that printing is clear, reliable in quality, usually the co-ordination stretch-draw of wishing screen cloth gets tighter, keeps half tone more smooth, and has good durability, this has just proposed requirements at the higher level to the intensity and the rigidity of screen frame, and be subjected to cross sectional shape, the size of screen frame, and length and materials limitations, some requires to have exceeded the scope that normal employed material allowed.Screen cloth Zhang Detai is tight, and the inconsistent bullet of size, plastic deformation are caused in the variant position of screen frame, makes the screen cloth unbalance stress conversely, and produces distortion, causes printing quality not meet required precision.If open too loosely, then the durability in the screen painting process influence printing quality again less than assurance, and the replacing half tone causes the waste of cost and material again.
Technology contents
At the deficiencies in the prior art, the purpose of this utility model is intended to provide a kind of half tone pretension fixing device, to guarantee the reliability of screen painting quality.
For achieving the above object, the utility model adopts following technical scheme:
A kind of half tone pretension fixing device, this half tone pretension fixing device comprise, power set, a steel wire tow line, two anchor clamps.
Technique scheme can also be optimized design by following technological means:
Described wherein anchor clamps are fixedlyed connected with described power set, and described steel wire tow line connects another anchor clamps and described power set.
Described anchor clamps can be regulated it and clamp size.
On the described power set device for testing tensile force is installed.
Described power set are provided with stopping means.
Described steel wire rope is equipped with displacement tester.
Described power set are cylinder or oil cylinder.
The half tone pretension fixing device that the utility model is set forth, its beneficial effect is, by clamping the relative both sides of screen frame, screen frame is preset an outside tension force, when throwing the net and fixedly the time, stress and distortion that the tension force of screen frame and screen cloth tension force produce offset, and screen cloth is expanded to smooth shape fully, to guarantee the accuracy of printing.
Description of drawings
A kind of half tone pretension fixing device of Fig. 1 the utility model structural representation;
Fig. 2 is the use schematic diagram of half tone pretension fixing device shown in Figure 1.
The specific embodiment
Below, in conjunction with the accompanying drawings the utility model is described further:
As Fig. 1, for a kind of half tone pretension fixing device of the present utility model, comprise cylinder 1, fixed installation anchor clamps 21 on the cylinder, the movable end of cylinder 1 connects steel wire tow line 3, the other end jockey 22 of steel wire tow line.
Said structure in use, as shown in Figure 2, two relative frames that its anchor clamps 21 and anchor clamps 22 clamp screen frame 4 respectively start cylinders 1, make steel wire tow line 3 tensions and the distance of further anchor clamps 21 and anchor clamps 22; In operating process, two above-mentioned half tone pretension fixing devices use simultaneously, simultaneously the relative edge of two couples of screen frame are inwardly strained, according to general mechanics general knowledge, make this screen frame have outside tension force, at this moment, stop the activity of cylinder 1, throw the net then and be fixed on the screen frame, unclamp anchor clamps, then screen frame produces the stress and the trend of outside resilience, has offset stress and distortion that screen cloth tension force produces, and screen cloth is expanded to smooth shape fully.
For enhance productivity and to the tension degree accurate control, the utility model is installed device for testing tensile force on cylinder, pulling force is controlled; The pulling force stopping means is installed on cylinder, is realized reaching and specify pulling force to stop automatically, realize automation mechanized operation; On steel wire rope, displacement tester can also be installed, displacement is monitored.
Anchor clamps of the present utility model can also be the adjustable anchor clamps of clamping distance, to mate the frame of various different size screen frames.
According to known mechanical general knowledge, power set of the present utility model can also be oil cylinders.
For a person skilled in the art, can make other various corresponding changes and distortion, and these all changes and distortion should belong within the protection domain of the utility model claim all according to technical scheme described above and design.
