Description

Technical Field

[0001] The utility model relates to the technical field of dripping equipment, in particular to a dripping device for diluting vinyl ester resin. Background Art

[0002] Vinyl ester resin is made by esterification reaction of epoxy resin and acrylic acid or methacrylic acid. Epoxy acrylate resin is currently the most widely used and largest-volume photocurable oligomer. Its photocuring speed is the fastest among all types of oligomers, and its cured coating film has the characteristics of high hardness, good gloss, corrosion resistance, heat resistance and excellent electrochemical properties. In addition, epoxy acrylate raw materials are widely available, low in price and simple in synthesis process. Therefore, it is one of the most widely used photosensitive resins in photocurable coatings.

[0003] Existing drippers for diluting vinyl ester resins usually use valve-controlled dripping. After the valve is opened, the styrene dilution solvent slowly flows into the vinyl ester resin. The dilution state is uninterrupted like a thin stream of water, which can easily lead to excessive dilution of the vinyl ester resin. In order to reduce the excessive dilution of the vinyl ester resin, it is necessary to form a dripping state when styrene falls. Therefore, a dripper for diluting vinyl ester resin is proposed.

A valve 11 is installed on the outer surface of the liquid outlet pipe 10. When the valve 11 is opened, the diluted vinyl ester resin is discharged from the liquid outlet pipe 10.

[0022] See also Figure 1-2The dilution box 1 is provided with a stirring assembly 9, which includes a motor 91, a stirring shaft 92 and a stirring blade 93. The motor 91 is fixedly mounted on the top of the dilution box 1, the stirring shaft 92 is fixedly mounted on the output shaft of the motor 91, the stirring shaft 92 is rotatably connected to the top wall of the dilution box 1, and the stirring blade 93 is fixedly mounted on the outer surface of the stirring shaft 92. When the motor 91 is started, the stirring shaft 92 and the stirring blade 93 rotate, gradually stirring the vinyl ester resin and styrene, thereby increasing the contact area between the vinyl ester resin and the styrene and ensuring the quality of the vinyl ester resin. The stirring blade 93 is located in the dilution box 1.

[0023] See also Figure 1-5 A circulating dripping assembly 8 for repeated dripping is provided on the support shell 5 and the installation box 7. The circulating dripping assembly 8 includes a movable frame 81, a perforation 82, a motor 83, a rotating body 84, a convex rib 85, a guide rib 86 and a roller 87. The movable frame 81 is slidably connected to the inner wall of the support shell 5. The movable frame 81 moves horizontally and laterally in the support shell 5. The top view shape of the movable frame 81 is T-shaped. The movable frame 81 is slidably connected to the side wall of the installation box 7. The perforation 82 is opened in the movable frame 81. The perforation 82 can move horizontally and laterally with the movable frame 81. The perforation 82 corresponds to the dilution tube 3 and the hopper 4. When the perforation 82 is connected to the dilution tube 3 and the hopper 4, dripping is performed. When the movable frame 81 corresponds to the dilution tube 3 and the hopper 4, the dilution tube 3 and the hopper 4 can be blocked to form diluted droplets between the connection and blocking switching.

[0024] In addition, the motor 83 is fixedly mounted on the side wall of the installation box 7, and the rotating body 84 is fixedly mounted on the output shaft of the motor 83. When the motor 83 is started, the rotating body 84 rotates, and the dripping work of styrene is gradually carried out. The rotating body 84 is rotationally connected to the installation box 7, and the convex rib 85 is fixedly connected to the outer surface of the rotating body 84. The shape of the convex rib 85 is an incomplete ring. The guide rib 86 is fixedly mounted on the outer surface of the rotating body 84 and fixedly connected to the convex rib 85. The convex rib 85 and the guide rib 86 can rotate with the rotating body 84. The shape of the guide rib 86 is V-shaped, which is conducive to guiding the movable frame 81 to move reciprocatingly horizontally, which is conducive to the dripping work.

[0025] At the same time, the roller 87 is rotatably connected to the bottom of the movable frame 81 and contacts the outer surfaces of the convex rib 85 and the guide rib 86. The rotation of the convex rib 85 and the guide rib 86 can push the movable frame 81, so that the movable frame 81 can repeatedly move laterally to realize the dripping process of styrene. There are two rollers 87, and the two rollers 87 are distributed on both sides of the convex rib 85 and the guide rib 86. The rotating body 84, the convex rib 85, the guide rib 86 and the roller 87 are all located in the installation box 7.

[0026] When the present embodiment is used, the vinyl ester resin is first introduced into the dilution box 1, and the motor 83 is started. The rotating body 84, the convex rib 85 and the guide rib 86 rotate, and the movable frame 81 and the perforation 82 are driven to move horizontally repeatedly under the connection of the roller 87, so that the styrene in the perforation 82 forms droplets and falls into the dilution box 1, and then the motor 91 is started, and the stirring shaft 92 and the stirring blade 93 rotate to mix and dilute the vinyl ester resin and the styrene. After the dilution is completed, the valve 11 is opened to discharge the diluted vinyl ester resin from the liquid outlet pipe 10.

[0027] The beneficial effects of the above embodiments are:

[0028] The vinyl ester resin dilution dripper is provided with a circulating dripping assembly 8. After use, the circulating dripping assembly 8 continuously rotates the rotating body 84, driving the convex rib 85 and the guide rib 86 to rotate, and under the connection of the roller 87, the movable frame 81 and the perforation 82 can reciprocate and move horizontally left and right. After the perforation 82 is connected with the dilution tube 3 and the hopper 4, styrene falls. When the perforation 82 corresponds to the support shell 5, the movable frame 81 can block the dilution tube 3 and the hopper 4, so that the styrene forms droplets and falls, thereby achieving the purpose of dripping dilution, reducing the impact of excessive styrene added at one time on the quality of the vinyl ester resin, and ensuring the effectiveness of styrene dilution.

[0029] The motor 83 and the motor 91 mentioned in the text are both electrically connected to the main controller and the power supply. The main controller can be a conventional known device for control such as a computer, and the existing public power connection technology is not described in detail in the text.
