Description

Technical Field

[0001] This utility model relates to the technical field of liquid photosensitive resin processing equipment, and in particular to a stirring processing 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, the production and processing of liquid photosensitive resin requires stirring. Generally, the liquid photosensitive resin material is transported into a mixing tank, where a stirring rod inside the tank mixes the material. After mixing, it is discharged from the output pipe at the bottom of the mixing tank. Due to the photosensitive properties of liquid photosensitive resin, exposure to external light sources must be avoided during stirring and transportation. However, when liquid photosensitive resin is mixed in a closed mixing tank, it is inconvenient for personnel to check the internal stirring and mixing process. Summary of the Invention

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

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a stirring and processing device for liquid photosensitive resin, comprising a barrel body and a barrel cover disposed thereon, a main rod disposed at the lower end of the barrel cover, a plurality of stirring rods sleeved on the outer wall of the main rod, the bottom end of the main rod being connected to the bottom side of the inner wall of the barrel body, a placement cavity being opened at the bottom end of the main rod, a through hole communicating with the placement cavity being opened on the bottom side of the inner wall of the barrel body, a conveying pipe being disposed in the placement cavity, one end of the conveying pipe extending out of the placement cavity and located outside the main rod, a storage box being disposed below the conveying pipe in the placement cavity, an opening communicating with the conveying pipe being opened on the storage box, and a solenoid valve being disposed on the conveying pipe.

[0006] Preferably, the storage box has an extension tube at its opening, the conveying pipe has an internal thread on the inner wall of the end facing the storage box, and the extension tube has an external thread on its outer wall that is screwed into the internal thread.

[0007] Preferably, a hollow rod is provided on the inner wall of the end of the extension cylinder facing the conveying pipe, a telescopic spring is vertically provided on the side of the hollow rod facing the storage box, a baffle is provided on the end of the telescopic spring away from the hollow rod, a positioning plate is provided on the inner wall of the end of the conveying pipe facing the extension cylinder, and a push rod is provided on the positioning plate along the length direction of the extension cylinder.

[0008] Preferably, the telescopic spring is fitted with a telescopic cover.

[0009] Preferably, a sealing ring is embedded at one end of the delivery pipe located inside the placement cavity.

[0010] Preferably, a knob is fitted on the outer wall of the storage box at the end away from the main rod.

[0011] Preferably, an observation window is embedded in the bottom side of the storage box, and a light shield is slidably disposed on the bottom side of the storage box at the observation window.

[0012] The beneficial effects of this utility model are as follows: By setting a placement cavity at the lower end of the main rod, and opening a through hole on the bottom side of the inner wall of the barrel that communicates with the placement cavity, the storage box can be inserted into the placement cavity through the through hole. The upper end of the storage box extends into the placement cavity and is connected to the inside of the barrel through a delivery pipe. The opening and closing of the delivery pipe is controlled by a solenoid valve, which makes it convenient for personnel to open and deliver liquid photosensitive resin into the storage box when needed. Compared with the prior art, this utility model makes it easier for personnel to collect and check the liquid photosensitive resin in the mixing barrel, avoiding the problem of excessive external light source shining on the liquid photosensitive resin in the barrel when it is necessary to check the processing status of the liquid photosensitive resin in the mixing barrel.

It should be noted that a sealed bearing (not shown in the attached figure) is provided at the rotatable point between the bottom end of the main rod 3 and the bottom side of the inner wall of the barrel body 1. The purpose of this is to prevent the liquid photosensitive resin in the barrel body 1 from flowing out through the cavity between the bottom end of the main rod 3 and the bottom side of the inner wall of the barrel body 1. A placement cavity 5 is provided at the bottom end of the main rod 3. A through hole 6 communicating with the placement cavity 5 is provided on the bottom side of the inner wall of the barrel 1. The through hole 6 is concentric with the main rod 3, and the inner diameter of the through hole 6 is smaller than the inner diameter of the main rod 3. A conveying pipe 7 is provided in the placement cavity 5. The front end of the conveying pipe 7 extends out of the placement cavity 5 and is located outside the main rod 3, and communicates with the inside of the barrel 1. A storage box 8 is provided in the placement cavity 5 below the conveying pipe 7. An opening 9 communicating with the conveying pipe 7 is provided on the storage box 8. An extension tube 12 is provided at the opening 9. The conveying pipe 7 faces... An internal thread 11 is provided on the inner wall of one end of the storage box 8, and an external thread 13 is provided on the outer wall of the extension cylinder 12 to engage with the internal thread 11. A solenoid valve 10 is provided on the conveying pipe 7. A hollow rod 14 is provided on the inner wall of the end of the extension cylinder 12 facing the conveying pipe 7. In this embodiment, the cross-section of the hollow rod 14 is T-shaped, and its upper end is provided with an inner chamfer (not shown in the figure). A telescopic spring 15 is vertically provided on the side of the hollow rod 14 facing the inside of the storage box 8. Two sets of telescopic springs 15 are provided, one on the left and one on the right of the hollow rod 14. At both ends of the right, and at the end of the telescopic spring 15 away from the hollow rod 14, a baffle 16 is connected. A positioning plate 17 is provided on the inner wall of the end of the conveying pipe 7 facing the extension cylinder 12. A push rod 18 is provided on the lower side of the positioning plate 17 along the length of the extension cylinder 12. The diameter of the push rod 18 is smaller than the inner diameter of the hollow rod 14. A telescopic cover 19 is sleeved on the outside of the telescopic spring 15. The upper end of the telescopic cover 19 is connected to the hollow rod 14, and its lower end is connected to the upper side of the baffle 16.

[0020] A knob 21 is fitted on the outer wall of the storage box 8 at the end away from the main rod 3, and an observation window 22 is embedded on the bottom side of the storage box 8. A light shield 23 is horizontally slidably installed on the bottom side of the storage box 8 at the observation window 22.

[0021] When personnel do not need to observe the processing and mixing state of the liquid photosensitive resin in the barrel 1, the solenoid valve 10 is in the closed state. The liquid photosensitive resin in the barrel 1 is stirred and mixed by the stirring rod 4 on the main rod 3 and will not be sent out through the delivery pipe 7. The storage box 8 is not screwed to the delivery pipe 7. The light shield 23 blocks the observation window 22. The telescopic spring 15 is in the retracted state, pulling the upper side of the baffle 16 to fit against the lower end surface of the hollow rod 14.

[0022] When personnel need to check the mixing state of the liquid photosensitive resin inside barrel 1, the rotation of the main rod 3 is paused. Then, the storage box 8 is inserted into the placement cavity 5 and screwed onto the inner wall of the delivery pipe 7 via the extension tube 12. During the screwing process, the extension tube 12 moves upward, and the push rod 18 enters the extension tube 12 through the hollow rod 14 and presses down the baffle 16. The telescopic spring 15 is pulled and extended, and the baffle 16 moves down into the interior of the storage box 8. Then, the solenoid valve 10 is opened, and the liquid photosensitive resin inside barrel 1 flows into the extension tube 12 through the delivery pipe 7 and into the storage box 8, delivering a... After a set time, the personnel control the solenoid valve 10 to close, the delivery pipe 7 to stop delivery, and then the personnel reverse the storage box 8. The storage box 8 begins to move out of the placement cavity 5, and the telescopic spring 15 will retract synchronously, pulling the baffle 16 back into the extension tube 12, and then attaching it to the lower surface of the hollow rod 14. After the personnel take out the storage box 8 containing liquid photosensitive resin, they can move to a suitable environment to check the condition of the liquid photosensitive resin. When it needs to be poured out, a set of long rods is inserted into the extension tube 12 to press down the baffle 16, and the storage box 8 is reversed to pour out the liquid photosensitive resin for personnel to check and understand.
