Description

Technical Field

[0001] The utility model relates to the technical field of screen coating, in particular to a screen photosensitive glue coater. Background Technique

[0002] Photosensitive glue, also known as photosensitive film or film, is generally uniformly coated on the screen through a coater. Then, a printed pattern is pasted on its surface. After plate exposure, the photosensitive glue in the exposed part on the screen hardens and remains as a covering layer of the screen with water resistance, while the unexposed part remains water-soluble. Later, the exposed screen is cleaned to remove the photosensitive glue in the unexposed part until the pattern is clear, and then the screen can be used for printing.

[0003] At present, most screen coatings use a coater for surface coating. The coater is a long strip-shaped tubular structure with an opening along its length at one end. After pouring the photosensitive glue into the coater, it is coated while pouring to coat a layer of photosensitive glue on the screen. In the prior art, since there is a frame at the edge of the screen, the coater generally has a fixed length, and a suitable coater needs to be selected according to the width of the screen to facilitate insertion inside the frame for coating. When coating screens of different sizes, multiple different coaters need to be prepared, increasing equipment investment. At the same time, it is not convenient to recycle the unused photosensitive glue. Summary of the Invention

[0004] The purpose of the utility model is to provide a screen photosensitive glue coater to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A screen photosensitive glue coater includes an inner tube, an outer tube movably sleeved outside the inner tube, and a fixing component for fixing the two. The outer tube can move back and forth along the length direction of the inner tube, and the opposite ends of the inner tube and the outer tube are provided with communicating openings. Openings for pouring glue are arranged on the outer peripheral walls of the inner tube and the outer tube along their length directions, and rubber squeegee strips are detachably arranged at the edges of the openings.

[0006] Further, both the inner tube and the outer tube are hollow prisms.

[0007] Further, the fixing component includes a fixing bracket fixed on the outer side wall of the inner tube along the length direction of the inner tube and a fixing bolt threadedly connected to the fixing bracket. The fixing bolt is located at one end of the fixing bracket close to the outer tube.

[0008] Further, a discharge end is arranged at one end of the outer tube away from the inner tube, one end of the discharge end is communicated with the inside of the outer tube, and a sealing cover is arranged at the other end of the discharge end.

[0009] Furthermore, the discharge end includes an outlet section and a transition section with a gradually decreasing size from the outer tube to the discharge end, and the sealing cover is threadedly connected to the outlet section.

[0010] Furthermore, a filtering structure is provided at one end of the outer tube close to the discharge end.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows: By providing an inner tube, an outer tube, and a fixing component, the overall length of the screen printing photosensitive glue coater can be adjusted according to the width of the screen, meeting different coating requirements and reducing equipment investment.

[0016] Please refer to Figure 1-2, An embodiment provided by the utility model: a screen printing photosensitive glue coater, which includes an inner tube 1, an outer tube 2 movably sleeved outside the inner tube 1, and a fixing component 3 for fixing the two. The outer tube 2 can move back and forth along the length direction of the inner tube 1, and openings communicating with each other are provided at one end of the inner tube 1 and the outer tube 2 facing each other. Openings for pouring glue are provided on the outer peripheral walls of the inner tube 1 and the outer tube 2 along their length directions, which is convenient for pouring glue. In this embodiment, both the inner tube 1 and the outer tube 2 are hollow prisms, so that the inner tube 1 and the outer tube 2 can only relatively slide in the length direction, avoiding relative rotation, resulting in misalignment of the openings for pouring glue, and at the same time, it is also convenient for the staff to take. Further, in order to improve the sealing performance, rubber gaskets can be provided on the outer side wall of one end of the inner tube 1 and the inner side wall of the outer tube 2.

[0017] The fixing component 3 includes a fixing bracket 301 fixed on the outer side wall of the inner tube 1 along the length direction of the inner tube 1 and a fixing bolt 302 threadedly connected to the fixing bracket 301. The fixing bracket 301 is an L-shaped structure, including a vertical section fixed to the inner tube 1 and a horizontal section parallel to the outer side wall of the inner tube 1. The fixing bolt 302 is located at one end of the horizontal section of the fixing bracket 301 close to the outer tube 2. After adjusting the position of the outer tube 2, the fixing bolt 302 can be rotated to press the outer tube 2 tightly against the outer side wall of the inner tube 1, realizing the relative fixation of the inner tube 1 and the outer tube 2. In this embodiment, only one group of fixing components 3 is provided. In order to improve the stability of the two, multiple groups of fixing components 3 can also be provided.

[0018] A rubber squeegee 4 is detachably provided at the edge of the opening. Specifically, an opening sleeved on the opening edges of the inner tube 1 and the outer tube 2 is provided on one side of the rubber squeegee 4, which is convenient for disassembly and assembly. The rubber squeegee 4 is in flexible contact with the screen, which can reduce the wear on the screen and improve the uniformity of coating at the same time. When a coater with a different length is needed, only the rubber squeegee 4 with a different length needs to be replaced, reducing equipment investment.

[0019] A discharge end 5 is provided at one end of the outer tube 2 away from the inner tube 1, and one end of the discharge end 5 is communicated with the inside of the outer tube 2. A sealing cover 6 is provided at the other end of the discharge end 5. In this embodiment, the discharge end 5 includes an outlet section 502 and a transition section 501 whose size gradually decreases from the outer tube 2 to the discharge end 5. The sealing cover 6 is threadedly connected to the outlet section 502. When the coating is completed, the coater is tilted, and the remaining photosensitive glue inside can be poured out through the discharge end 5 for recycling, which is convenient to use.

[0020] A filtering structure is provided at one end of the outer tube 2 close to the discharge end 5. In this embodiment, the filtering structure is a plurality of filter holes 201 provided on the side wall of one end of the outer tube 2, which can filter out impurities entering the photosensitive glue before recycling. Further, the filtering structure can also be set as a detachable filter screen according to needs.

[0021] Working principle: By pulling the inner tube 1 or the outer tube 2, the overall length is adjusted. At the same time, the outer tube 2 slides back and forth between the fixed bracket 301 and the outer side wall of the inner tube 1. Rotate the fixing bolt 302 to press the outer tube 2 tightly against the outer side wall of the inner tube 1, and the relative fixation of the inner tube 1 and the outer tube 2 can be achieved. Then select a rubber squeegee 4 with an appropriate length and fix it at the opening edges of the inner tube 1 and the outer tube 2. During coating, pour the photosensitive glue into the inner tube 1 and the outer tube 2 through the opening. Press the rubber squeegee 4 against the bottom end of the screen plate, and apply the photosensitive glue upward while pouring. After the coating is completed, unscrew the sealing cap 6, and it is convenient to recycle the remaining photosensitive glue through the discharge end 5.
