Description

Technical Field

[0001] The utility model relates to the technical field of screen printing, in particular to a screen printing stencil. Background Art

[0002] Screen printing refers to a method of obtaining a pattern by using a stencil and printing ink. The screen printing process is simple, has high production efficiency and low cost, and is suitable for mass production.

[0003] At present, the stencils for screen printing mainly consist of a screen frame and a screen. The surface of the screen usually needs to be covered with a photosensitive material. During printing, the ink can be printed on the surface of the substrate through the mesh holes on the surface of the screen. Therefore, the cleanliness of the screen is very important for the subsequent printing effect. At present, when some screen printing stencils are idle, the staff needs to use a plastic film to wind the screen frame to protect the screen. However, when using this protection method, it is not only easy to cause material loss, that is, the plastic film is difficult to be reused, but also easy to affect the use efficiency, that is, it is time-consuming for the staff to wind the plastic film around the screen frame one by one, so that the overall efficiency of screen printing will be affected. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a screen printing stencil to solve the problems put forward in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A screen printing stencil, including a screen frame body and a screen body fixedly connected to the bottom of the screen frame body, further including:

[0006] A T-shaped groove opened on the surface of the screen frame body and a T-shaped plate slidably connected to the inside of the T-shaped groove.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-6As shown in the figure, a screen printing stencil includes a frame body 1 and a screen body 2 fixedly connected to the bottom of the frame body 1. A T-shaped groove 3 is formed on the surface of one side of the frame body 1. A T-shaped plate 4 is slidably connected inside the T-shaped groove 3. A fixing plate 5 is fixedly connected to the surface of the T-shaped plate 4. An adjusting plate 6 is hinged to the surface of the fixing plate 5. Rectangular grooves 7 are formed above and below the surface of the adjusting plate 6. A rectangular plate 8 is slidably connected inside the rectangular groove 7. The number of the rectangular plates 8 is two. Positioning grooves 21 are formed on the surfaces of the opposite sides of the two rectangular plates 8. One end of the rectangular plate 8 is fixedly connected with a pulling plate. A baffle 9 is fixedly connected to the surface of the rectangular plate 8. The surface of the baffle 9 is in contact with the surface of the adjusting plate 6. The connection between the rectangular plate 8 and the adjusting plate 6 can be restricted through the arrangement of the baffle 9 and the pulling plate. A groove 10 is formed at the bottom of the fixing plate 5. After the adjusting plate 6 rotates, the groove 10 can be used in cooperation with the adjusting plate 6 and the baffle 9. A cylindrical groove 11 is formed on the surface of the frame body 1. A limiting mechanism 12 is arranged inside the cylindrical groove 11. A cavity 13 is formed inside the frame body 1. Lead screws 14 are rotatably connected to the top and bottom of the inner wall of the cavity 13. One end of each lead screw 14 is fixedly connected with a disc 15. An adjusting mechanism 16 is arranged on the surface of the disc 15. A threaded collar 17 is sleeved on the surface of the lead screw 14. The surface of the threaded collar 17 is in contact with the surface of the disc 15. The diameter of the disc 15 is larger than that of the lead screw 14. The number of the threaded collars 17 is two. The top of the upper threaded collar 17 and the bottom of the lower threaded collar 17 are respectively fixedly connected with a first guide rod 18 and a second guide rod 19. One end of each of the first guide rod 18 and the second guide rod 19 is fixedly connected with a positioning disc 20. Chute grooves are formed at the top and bottom of the frame body 1. The surface of the positioning disc 20 is slidably connected with the inner wall of the chute groove. The first guide rod 18 and the second guide rod 19 both slidably penetrate through the frame body 1. The surface of the positioning disc 20 is in contact with the inner wall of the positioning groove 21.

[0025] The limiting mechanism 12 includes a connecting rod 121 and a limiting plate 122. The surface of the connecting rod 121 is rotatably connected with the inner wall of the cylindrical groove 11. The number of the limiting plates 122 is two. The two limiting plates 122 are respectively fixedly connected to the two ends of the connecting rod 121. The surface of the limiting plate 122 is in contact with the surface of the frame body 1. The surface of the limiting plate 122 is in contact with the surface of the T-shaped plate 4. The position of the T-shaped plate 4 can be restricted through the arrangement of the connecting rod 121 and the limiting plate 122. When the staff needs to disassemble the T-shaped plate 4, they can rotate one of the limiting plates 122. At this time, with the cooperation of the connecting rod 121, the other limiting plate 122 can rotate simultaneously. Accordingly, the staff can take out the T-shaped plate 4 from the inside of the T-shaped groove 3.

[0026] The adjusting mechanism 16 includes a rotating shaft 161, bevel gears 162, a bevel gear disc 163, and a vertical rod 164. The rotating shaft 161 rotates through the screen frame body 1. One end of the rotating shaft 161 is fixedly connected to a turntable. The bevel gear 162 is fixedly connected to the other end of the rotating shaft 161. Both ends of the vertical rod 164 are respectively fixedly connected to the two lead screws 14. The bevel gear disc 163 is fixedly sleeved on the surface of the vertical rod 164. The bevel gear 162 meshes with the bevel gear disc 163. When the staff rotates the turntable, the rotating shaft 161 drives the bevel gear 162 to rotate. At this time, the vertical rod 164 rotates accordingly to drive the lead screw 14 to rotate. The thread directions of the two lead screws 14 are opposite. The diameter of the bevel gear disc 163 is larger than the diameter of the disc 15. Accordingly, it is convenient to adjust the distance between the two threaded collars 17.

[0027] Working principle: When this screen printing plate is idle, the staff can adjust this screen printing plate to the Figure 1 state shown in the figure. At this time, the two rectangular plates 8 can protect the top of the screen frame body 1 and the bottom of the screen body 2. And when the positioning disc 20 is placed inside the positioning groove 21, the positions of the two rectangular plates 8 can be fixed. Accordingly, the possibility of the screen body 2 being polluted can be reduced;

[0028] When this screen printing plate needs to be used, the staff rotates the turntable, and the bevel gear disc 163 rotates accordingly to drive the lead screw 14 to rotate through the disc 15. Accordingly, the two threaded collars 17 respectively drive the two positioning discs 20 to move out of the two positioning grooves 21 through the first guide rod 18 and the second guide rod 19, and move into the inside of the chute, so as to release the fixation of the position of the rectangular plate 8. After that, the staff pulls the pull plate, and the rectangular plate 8 moves accordingly to release the protection of the screen frame body 1 and the screen body 2. Finally, the staff rotates the adjusting plate 6 to place the rectangular plate 8 vertically, so that the screen frame body 1 and the screen body 2 can be used normally. After that, the staff pours the ink into the inside of the screen frame body 1, that is, pours it on the top of the screen body 2, and then can use a squeegee for screen printing.
