Description

Technical Field

[0001] This utility model relates to the technical field of dispensing equipment for liquid photosensitive resin, and in particular to a dispensing device for liquid photosensitive resin. Background Technology

[0002] Liquid photosensitive resin is a polymer material that is cured through photochemical reaction under ultraviolet light irradiation. It is mainly composed of oligomers, photoinitiators, and diluents. Its core characteristic is that after the photoinitiator absorbs ultraviolet light of a specific wavelength, it generates active groups, which triggers the cross-linking polymerization of resin molecules to form a stable solid structure.

[0003] Traditionally, after the liquid photosensitive resin is manufactured, it needs to be dispensed from the reactor into various storage tanks. This is done by setting several output pipes at the outlet of the reactor and connecting them to each storage tank. However, since the pipes are located on the outside, if the pipes are damaged by external force during the dispensing process, personnel need to shut off the liquid photosensitive resin supply to replace the pipes, which can easily affect the overall delivery efficiency of the liquid photosensitive resin. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a dispensing device for liquid photosensitive resin.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a dispensing device for liquid photosensitive resin, comprising a plurality of output pipes disposed at each group of outlets of a reaction vessel, each output pipe comprising a side tube plate one and a side tube plate two, the side tube plate one and the side tube plate two being arranged opposite to each other, and each having an extension plate on its outer wall, the two sets of extension plates being screwed together, a fixed tube being disposed inside the output pipe at the outlet of the reaction vessel, a support being disposed at the lower end of the reaction vessel, the end of the output pipe away from the reaction vessel being connected to the inner wall of the support, a through hole being opened on the support, an auxiliary tube being slidably disposed at the through hole opposite to the fixed tube, and the upper end of the auxiliary tube passing through the support and located inside the output pipe, a pusher being disposed on the outer wall of the auxiliary tube, the pusher being driven to move the auxiliary tube along the length direction of the output pipe.

[0006] Preferably, the pusher includes a telescopic air pipe disposed on the side of the auxiliary pipe away from the fixed pipe and an air pump disposed on the bracket, the air pump being connected to the telescopic air pipe.

[0007] Preferably, the inner wall of the output pipe is provided with a sliding groove, and the upper end of the auxiliary pipe is slidably connected to the sliding groove.

[0008] Preferably, a sealing ring one is embedded in the side of the fixed tube facing the auxiliary tube, a sealing ring two is embedded in the upper end of the auxiliary tube away from the fixed tube, and a sealing ring three is embedded in the lower side of the bracket directly above the lower end of the auxiliary tube.

[0009] Preferably, a sealing strip is embedded along the length of the side tube plate one facing the side tube plate two.

[0010] Preferably, the fixed tube is provided with a plug on the side facing the auxiliary tube, and the upper side of the auxiliary tube is provided with a slot for plugging into the plug.

[0011] The beneficial effects of this utility model are as follows: By setting a fixed tube for outputting liquid photosensitive resin under the reactor, and covering the fixed tube with an output pipe fitting, the output pipe fitting is divided into a left tube plate and a right tube plate. By screwing together the expansion plate on the outer wall, a set of pipes for transporting liquid photosensitive resin is fixed. A support is set on the lower side of the reactor, and an auxiliary tube with one end that can extend into the output pipe fitting is slidably set on the support. A telescopic air pipe is set on the lower side of the upper end of the auxiliary tube and is connected to the telescopic air pipe through an air pump. Compared with the prior art, this utility model can push the telescopic air pipe with a cylinder to make the auxiliary tube and the fixed tube fit and connect in the output pipe fitting. Thus, the damaged output pipe fitting can be disassembled and replaced without affecting the output of liquid photosensitive resin, without stopping the dispensing and transportation of liquid photosensitive resin, reducing the impact on the overall transportation efficiency of liquid photosensitive resin.

[0023] like Figures 1 to 6 As shown, a dispensing device for liquid photosensitive resin includes several sets of output pipes disposed at each group of outlets of a reactor 1. In this embodiment, the output pipes include a side tube plate 2 and a side tube plate 3 with an arc-shaped design. The side tube plate 2 and the side tube plate 3 are arranged opposite to each other and can be assembled into a hollow cylinder. Each of them is provided with an extension plate 4 on its outer wall. The two sets of opposite extension plates 4 are screwed together by bolts and nuts to achieve the splicing between the side tube plate 2 and the side tube plate 3. Disassembly can be achieved by unscrewing the bolts and nuts to separate the side tube plate 2 and the side tube plate 3.

[0024] A U-shaped support 6 is installed on the lower outer wall of the reactor 1. A fixed pipe 5 is installed inside the output pipe at the outlet of the reactor 1. The end of the output pipe furthest from the reactor 1 is connected to the upper inner wall of the support 6. Several sets of through holes 7 are opened on the support 6, the number of which is the same as the number of output pipes on the reactor 1. The inner diameter of each through hole 7 is smaller than the inner diameter of the cylinder formed by the assembly of side pipe plate 2 and side pipe plate 3. An auxiliary pipe 8 is slidably installed at each through hole 7, concentrically positioned opposite the fixed pipe 5. The upper end of the auxiliary pipe 8 passes through the support 6 and is located inside the output pipe. A communicating groove 11 is opened on the inner walls of side pipe plate 2 and side pipe plate 3, extending along the height direction of the output pipe. Assume that the upper end of the auxiliary tube 8 is slidably connected to the slide groove 11, and a sealing ring 12 is embedded on the side of the fixed tube 5 facing the auxiliary tube 8. The outer diameter of the sealing ring 12 is smaller than the outer diameter of the upper end of the auxiliary tube 8 and larger than the inner diameter of the upper end of the auxiliary tube 8. A sealing ring 23 is embedded on the side of the upper end of the auxiliary tube 8 away from the fixed tube 5, and a sealing ring 34 is embedded on the lower side of the bracket 6 directly above the lower end of the auxiliary tube 8. A sealing strip 15 is embedded along the length of the side tube plate 12 facing the side tube plate 23. The purpose is to reduce gaps at the points where the fixed tube 5 and the auxiliary tube 8 are in contact, the points where the auxiliary tube 8 and the bracket 6 are in contact, and the points where the side tube plate 12 and the side tube plate 23 are in contact, so as to prevent leakage when the liquid photosensitive resin flows through.

[0025] Telescopic air pipes 9 are vertically arranged at the upper and lower sides of the auxiliary pipe 8. The lower end of the telescopic air pipe 9 is provided with a through hole 7 located at the lower end of the support 6. In this embodiment, the cross-section of the through hole 7 is T-shaped. An air pump 10 is provided on the lower side of the outer wall of the support 6. The output end of the air pump 10 is connected to the telescopic air pipe 9.

[0026] A plug 16 is provided on the side of the fixed tube 5 facing the auxiliary tube 8. A slot 17 is provided on the upper side of the auxiliary tube 8 to engage with the plug 16. The purpose is to limit the position between the auxiliary tube 8 and the fixed tube 5 by engaging the slot 17 and the plug 16 when the upper side of the auxiliary tube 8 is attached to the lower side of the fixed tube 5, so as to prevent the auxiliary tube 8 from being pushed to the left or right when it is subjected to external force or the internal liquid photosensitive resin moves.

[0027] When the output pipe is normally guiding the liquid photosensitive resin through, the telescopic air pipe 9 is in a compressed state, the air pump 10 is in a stopped state, the auxiliary pipe 8 is located at the lower end of the output pipe, and the sealing ring 13 on the lower side of the upper end of the auxiliary pipe 8 is attached to the lower side of the inner wall of the slide 11. The liquid photosensitive resin in the reactor 1 flows from the outlet through the fixed pipe 5, the output pipe and the auxiliary pipe 8 into the dispensing tank (not shown in the attached figure).

[0028] When the outer wall of the output pipe is damaged by impact and leaks, the personnel control the air pump 10 to start through the control system to inflate the telescopic air pipe 9. Since the upper end of the auxiliary pipe 8 is limited to sliding in the slide groove 11, the telescopic air pipe 9 moves vertically upward, pushing the upper end of the auxiliary pipe 8 to fit with the fixed pipe 5. The sealing ring 12 on the lower side of the fixed pipe 5 fits with the upper side of the upper end of the auxiliary pipe 8. At the same time, the insert 16 and the slot 17 are inserted and matched to limit the position of the auxiliary pipe 8. The upper side of the lower end of the auxiliary pipe 8 fits with the sealing ring 14 on the outer wall of the bracket 6. At this time, the personnel can disassemble and separate the side pipe plate 2 and the side pipe plate 3 that make up the output pipe for replacement. During the replacement process, the liquid photosensitive resin in the reactor 1 flows into the dispensing tank through the fixed pipe 5 and the auxiliary pipe 8.

[0029] It should be noted that, in this embodiment, the liquid photosensitive resin in the reactor 1 can be discharged by natural flow or by conveying by a pump. After the air pump 10 inflates the telescopic air pipe 9, the thrust of the telescopic air pipe 9 is greater than the downward pressure exerted by the liquid photosensitive resin on the auxiliary pipe 8 in the output pipe.

[0030] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
