Description

Technical Field

[0001] The utility model relates to the technical field of photosensitive adhesive production, in particular to a defoaming device for photosensitive adhesive production. Background Art

[0002] Photosensitive adhesive is also called photosensitive emulsion or photoresist. It and photosensitive film (also called film) are currently commonly used photosensitive materials. Photosensitive adhesive is used for direct plate making. It is generally divided into single-liquid type and double-liquid type. Single-liquid photosensitive adhesive has photosensitizer mixed into latex during production, so it can be used without preparation. Before using double-liquid photosensitive adhesive, photosensitizer must be dissolved in water according to the formula, then mixed in latex, stirred thoroughly and left for 1-2 hours. It can be used after the bubbles disappear completely.

[0003] During the production process of photosensitive adhesive, due to the presence of bubbles, it is difficult to eliminate the bubbles for a while, which affects the efficiency of production and use. Most of the existing defoaming devices are defoaming thorns, which can easily defoam the bubbles on the surface of the photosensitive adhesive. The bubbles inside the photosensitive adhesive need to be moved to the inside of the photosensitive adhesive. Bubbles are very easy to be generated during the movement process, which reduces its work efficiency and product quality. For this reason, we propose a defoaming device for photosensitive adhesive production. Utility Model Content

[0024] like Figure 1-Figure 5As shown, a defoaming device for photosensitive adhesive production comprises a placing barrel 1, a fixing frame 2 is fixedly connected to the top outer surface of the placing barrel 1, two limiting grooves 9 are provided on one side surface of the fixing frame 2, a servo motor 3 is fixedly connected to the one side surface of the fixing frame 2, a connecting rod 4 is fixedly connected to the output end of the servo motor 3, a movable block 5 is fixedly connected to the outer surface of one end of the connecting rod 4, the outer surface of the movable block 5 is movably connected to the fixed block 6, a moving groove 7 is provided on one side surface of the fixed block 6, the outer surface of the movable block 5 is movably connected to the inner wall of the moving groove 7, the other side surface of the fixed block 6 is fixedly connected to a movable rod 8, the outer surface of the movable rod 8 is movably connected to the inner wall of the limiting groove 9, a material barrel 17 is fixedly connected to the one end surface of the movable rod 8, a connecting block 18 is fixedly connected to the top surface of the material barrel 17, a plurality of evenly distributed slide grooves 19 are provided on the surface of the connecting block 18, a sliding rod 11 is movably connected to the inner wall of the sliding groove 19, and the bottom end of the sliding rod 11 is fixedly The top of the slide bar 11 passes through a slide groove 19 and is fixedly connected to a top block 14. A return spring 12 and a return spring 2 13 are sleeved on the outer surface of the slide bar 11. A connecting pipe 10 is provided at the bottom end of the placement barrel 1. A return spring 3 15 is fixedly connected to the bottom surface of the placement barrel 1. A fixing ring 16 is fixedly connected to the top of the return spring 3 15. The surface of the fixing ring 16 is fixedly connected to the outer surface of the bottom end of the material barrel 17. A connecting frame 21 is movably connected to the outer surface of the slide bar 11. A movable ring 20 is fixedly connected to one side surface of the connecting frame 21. The inner wall of the movable ring 20 is tightly fitted to the outer surface of the bottom end of the material barrel 17. A slide groove 22 is provided on the surface of the connecting frame 21. The inner wall of the slide groove 22 is movably connected to the outer surface of the slide bar 11 and is located between the return spring 12 and the return spring 2 13. A discharge pipe 23 is fixedly connected to the bottom surface of the material barrel 17. The bottom end of the discharge pipe 23 passes through the connecting pipe 10.

[0025] The working principle of the above technical solution is as follows:

[0026] When it is necessary to defoam the photosensitive adhesive, first pour the photosensitive adhesive into the barrel 17. At this time, the servo motor 3 can be driven so that the output end of the servo motor 3 drives the connecting rod 4 to rotate, and the connecting rod 4 can drive the movable block 5 to rotate, so that the movable block 5 can move on the surface of the fixed block 6, and the outer surface of the movable block 5 can move on the inner wall of the movable groove 7. When the movable block 5 moves under the movable groove 7, the movable block 5 can drive the movable groove 7 to move downward. When the movable groove 7 moves downward, it can drive the movable rod 8 to move vertically, so that the movable rod 8 can move on the inner wall of the limiting groove 9. When the movable rod 8 moves vertically, the connecting block 18 can be pushed to drive the barrel 17, the movable ring 20 and the fixed ring 16 to move vertically. When the barrel 17 moves vertically, it can move on the outer surface of the slide rod 11 through the slide groove 19, so that the connecting block 18 squeezes the reset spring 12. At this time, the movable ring 20 can drive the connecting frame 21 to move vertically, and the connecting frame 21 can be connected through the slide groove 19. The second slide groove 22 moves on the outer surface of the slide rod 11, so that the connecting frame 21 squeezes the reset spring 2 13, and the fixed ring 16 moves vertically, which can squeeze the reset spring 3 15. Since the reset spring 12, the reset spring 2 13 and the fixed ring 16 have resilience, they can respectively drive the connecting block 18, the connecting frame 21 and the fixed ring 16 to move and reset. When the barrel 17 moves back and forth vertically, the photosensitive glue in the barrel 17 can be shaken and vibrated, so that the photosensitive glue can be The bubbles inside the glue move to its surface and can be defoamed. When the barrel 17 moves vertically, it can drive the discharge pipe 23 to move vertically. When all the bubbles inside the photosensitive glue move to the surface, the photosensitive glue without bubbles can flow in through the discharge pipe 23. The top block 14 can limit the height of the reciprocating vertical movement of the barrel 17. The setting of this device can facilitate the defoaming of bubbles in the photosensitive glue, shorten the defoaming time, and improve work efficiency.

[0027] The above embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
