Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of photosensitive adhesive production, and particularly relates to a photosensitive adhesive self-service production system. BACKGROUND

[0002] Photosensitive adhesive is a photosensitive material used in the fields of silk screen printing and semiconductor manufacturing, etc. It and photosensitive film are both currently commonly used photosensitive materials, and it can undergo chemical or physical changes under the action of light to form a pattern. In production, photosensitive adhesive is usually made by stirring gelatin, polyvinyl alcohol, nylon, etc. as a matrix and adding a photosensitizer, then fully stirring and dissolving in emulsion and placing for 1-2 hours before use after the bubbles completely disappear. A stirring mechanism is used in the production process to stir the raw materials for producing photosensitive adhesive. However, a single stirring method needs a long time of stirring to completely and uniformly stir, which reduces the homogenization efficiency of the photosensitive adhesive raw materials. Photosensitive adhesive is inconvenient to scrape off after adhering to the inner wall of the kettle body, especially after a period of time, it needs to be more firmly adhered.

[0003] In order to solve the above problems, the present application is born. SUMMARY

[0023] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application is further described in detail below in combination with specific embodiments and with reference to the drawings.

[0024] Referring to the drawings Figures 1-2 As shown in the drawings, a photosensitive adhesive self-service production system includes a kettle body, which is divided into an upper kettle body 2, a lower kettle body 1 and an inner shrink adapter 3 in the middle part from top to bottom. A stirring shaft 6 is passed through the middle part of the kettle body, wherein the stirring shaft 6 is provided with an upper stirring rod 5 and a lower stirring rod 4, and is located in the upper kettle body 2 and the lower kettle body 1 respectively. The upper stirring rod 5 and the lower stirring rod 4 are arranged at intervals, and the interval is greater than the height of the inner shrink adapter 3.

[0025] The connecting sleeve 7 is fixedly installed on the stirring shaft 6, wherein the upper stirring rod 5 and the lower stirring rod 4 at the corresponding position are hingedly connected with the connecting sleeve 7, as shown in the drawings Figure 1 As shown in the drawings, the position of the lower stirring rod 4 in the normal state is shown, and the hinged lower stirring rod 4 can control the position of lifting according to the rotating speed of the stirring shaft 6, that is, the faster the rotating speed of the stirring shaft 6, the higher the position of the lower stirring rod 4 is lifted, and the stirring position of the lower stirring rod 4 can be flexibly changed according to the change of the rotating speed, so that the adhesive in the relatively inner side and the adhesive in the outer side in the lower kettle body 1 are more fully mixed.

[0026] The elastic pull rope 8 is tightened after being collected between the two adjacent upper stirring rods 5, so that the position is more and more lowered as the rotating speed of the stirring shaft 6 is greater, and the elastic rope is stretched (after speed reduction, the elastic rope is restored to continue to lift upward), so that the adhesive in the relatively inner side and the adhesive in the outer side in the upper kettle body 2 are more fully mixed.

[0027] The kettle body adopts the structure of large upper and lower parts and small middle part, so that the adhesive is more easily formed into a circulating flow during stirring, especially in the narrow middle part, the adhesive will be subjected to a large shear force, be quickly dispersed and flow upward and downward. This circulating flow mode makes the adhesive quickly and uniformly mixed in the kettle, reduces the aggregation or stratification of local materials, and further enables the adhesives in the upper and lower kettle bodies 1 to be fully mixed.

[0028] Further, by the shape design of the kettle body, the upper stirring rod 5 and the lower stirring rod 4 can be combined to the bottom inner wall of the upper kettle body 2 and the upper inner wall of the lower kettle body 1 with the expansion of the stirring speed when the inside is empty (the stirring rod generally cannot resist the inner wall of the kettle body due to the force of the colloid generally cannot be stirred), and the colloid residue on the inner wall of the kettle body is repeatedly scraped during the continuous rotation process, realizing the cleaning operation after the stirring of the kettle body.

[0029] Secondly, the colloid stirred by the mechanical stirring rod can promote the merging and floating of the bubbles, and when the colloid is stirred, the internal bubbles are easy to merge into large bubbles due to collision, and the large bubbles form larger buoyancy and quickly rise to the upper layer of the colloid.

[0030] Referring to the accompanying drawings Figures 3-4 As shown, the elastic pull rope 8 connected to the upper stirring rod 5 is replaced, and a disc-shaped filter bag 9 (which can be woven from elastic fibers, for example) is used. The pores of the filter bag 9 are as small as possible, and the material is elastic. The outer circle and radial position of the filter bag 9 can be supported by a larger elastic rope body 10. The upward floating bubbles are trapped by the pores of the filter bag 9 on the upper side, realizing the separation of bubbles and liquid. The filter bag 9 can continuously expand and contract with the upper stirring rod 5, further dispersing and trapping the floating bubbles.

[0031] The above specific embodiments further illustrate the purpose, technical solutions and advantages of the present application. It should be understood that the above description is only a specific embodiment of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application should be included in the protection scope of the present application.
