Description

Screen printing screen plate capable of accurately controlling printing size

Technical Field

The utility model relates to a silk screen field especially relates to a compound silk screen of printing down accurate control of version size.

Background

The silk screen printing refers to that a silk screen is used as a plate base, and a silk screen printing plate with pictures and texts is manufactured by a photosensitive plate making method. The using method comprises the following steps: when printing, ink or slurry is poured into one end of the screen printing plate, a scraper is used for applying certain pressure to the ink or slurry position on the screen printing plate, meanwhile, the scraper moves towards the other end of the screen printing plate at a constant speed, the ink or slurry is extruded onto a printing stock from meshes of the image-text part by the scraper in the moving process, and a specific pattern is displayed on the printing stock, namely, the screen printing is realized.

As can be seen from the above-mentioned method of use, if different patterns are required, different screens need to be produced, and if the patterns are different in size, the screen sizes required will also be different. The basic process of printing in the production of the screen printing plate is that the screen cloth is coated with the photosensitive glue, the screen cloth coated with the photosensitive glue is attached to a plate-making negative film with patterns, and the plate is printed in a printing machine, and the printing machine finishes printing in dozens of seconds or minutes. When printing down, the rubber skin on the machine of printing down can laminate with the screen cloth under the evacuation state, if be jumbo size screen cloth (surpassing a meter's screen cloth), the screen cloth size is too big, the rubber skin can make the screen cloth expansion, the pattern and the screen cloth contact on the negative of making a plate this moment can form the pattern on the screen cloth, but the vacuum state disappears the back, the screen cloth can contract, the pattern can diminish promptly, with the pattern size on the negative of making a plate inconsistent, lead to subsequent screen cloth to use and cause the obstacle, the failure of printing down promptly.

Therefore, the inventor of the present invention aims to provide a screen printing plate with accurately controlled printing size, which aims to solve the above technical problems.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects, the utility model aims to provide a screen printing plate for accurately controlling printing size.

In order to achieve the above purpose, the utility model discloses a technical scheme is: the utility model provides a screen printing half tone of printing down accurate control of size, includes the screen frame, the center of screen frame is provided with the silk screen, just the silk screen stretches tight the setting on the screen frame, just be provided with the pattern district on the silk screen, just be in setting up outside sensitization glued membrane layer around the pattern district, be in simultaneously the inside in pattern district sets up inside sensitization glued membrane layer, just inside sensitization glued membrane layer enables the pattern district forms specific pattern the scraper face of silk screen still sets up the protection film, and under the exogenic action, the protection film can be got rid of.

Preferably, one side of the protection film is provided with an adhesive layer, and one side of the adhesive layer is provided with a release film. When the protection film used promptly, get rid of the parting film, then paste the scraper face at the silk screen with the protection film that has the tie coat, before the printing down machine prints the version, set up the protection film, place the half tone on the printing down machine this moment, the rubber skin above the printing down machine can contract under vacuum condition, and wrap up the half tone, at this moment, because scrape the knife face and set up the protection film, when the rubber skin wraps up the half tone under vacuum condition, because the existence of protection film, the rubber skin can not direct contact silk screen (screen cloth in the background art), consequently, the expansion effect to the silk screen reduces to the minimum, make the size of the pattern on the silk screen obtain accurate control.

Preferably, the specific pattern of said pattern area consists of a mesh on a wire mesh. During printing, ink or slurry enters the printing surface from the mesh through the scraper surface, and then a specific pattern is displayed on a printing stock, so that the aim of screen printing is fulfilled.

Preferably, the internal photosensitive film layer is provided in plurality, and a plurality of the internal photosensitive film layers form a specific pattern in the pattern area. The design of the pattern is realized through the arrangement of the internal photosensitive film layer, and the design completeness of the pattern in the pattern area is ensured.

Preferably, the net frame is rectangular and is integrally formed. Guarantee the stability of whole screen frame promptly, when carrying out screen printing, guarantee the holistic stability of pattern, when preventing the scraper blade coating, cause the distortion of pattern.

Preferably, the screen frame is made of an aluminum alloy material. The screen frame is guaranteed to have certain mechanical strength, and meanwhile, the quality is light, and the screen frame is convenient for a user to use.

The utility model relates to a print down the screen printing screen of accurate control of version size's beneficial effect is, through when printing down the version, increase the protection film, guarantee the stability of pattern size on the large-size screen printing screen, when having prevented to print down under the vacuum condition, to the expansion of the silk screen size on the screen printing screen, and then cause the deformation of pattern.

Detailed Description

The following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so as to enable those skilled in the art to more easily understand the advantages and features of the present invention, and thereby define the scope of the invention more clearly and clearly.

Referring to fig. 1-4, the screen printing plate for accurately controlling printing size in the present embodiment includes a screen frame 1, a screen 2 is disposed in the center of the screen frame 1, the screen 2 is tightly disposed on the screen frame 1, a pattern area 3 is disposed on the screen 2, an external photosensitive adhesive film layer 4 is disposed around the pattern area 3, an internal photosensitive adhesive film layer 5 is disposed inside the pattern area 3, the internal photosensitive adhesive film layer 5 enables the pattern area 3 to form a specific pattern, a protective film 6 is further disposed on a scraper surface of the screen 2, and the protective film 6 can be removed under an external force.

One side of the protection film 6 is provided with an adhesive layer 7, and one side of the adhesive layer 7 is provided with a release film 8. When protection film 6 used promptly, will get rid of from parting film 8, then paste the scraper face at silk screen 2 with protection film 6 that has tie coat 7, before the printing down machine prints down the version, set up protection film 6, place the half tone this moment on the printing down machine, the rubber skin above the printing down machine can contract under vacuum condition, and wrap up the half tone, at this moment, because the knife scraping face sets up protection film 6, the rubber skin is when wrapping up the half tone under vacuum condition, because the existence of protection film 6, the rubber skin can not direct contact silk screen 2 (the screen cloth in the background art), consequently, the expanding effect to silk screen 2 reduces to the minimum, make the size of the pattern on silk screen 2 obtain accurate control.

The specific pattern of the pattern area 3 consists of meshes on the screen 2. During printing, ink or slurry enters the printing surface from the mesh through the scraper surface, and then a specific pattern is displayed on a printing stock, so that the aim of printing the silk screen 2 is fulfilled.
