Description

Technical Field

[0001] The invention relates to the technical field of water-based UV resin preparation, and in particular to a stirring device for preparing water-based UV resin. Background Art

[0002] Water-based UV resin is a kind of UV resin that is soluble in water or dispersible in water, with low viscosity. Its molecules contain a certain number of strong hydrophilic groups, such as carboxyl, hydroxyl, amino, ether, amide, etc., and unsaturated groups, such as acryloyl, methacryloyl or allyl. This structure enables water-based UV resin to form a stable dispersion or emulsion in water and other liquid media, and at the same time have the ability of UV curing. In addition, different color developers and modifiers are added as needed, and commonly used modifiers are silicone, aluminum oxide and SiO2 nanoparticles. Adding silicone can improve the comprehensive performance of water-based UV resin; adding aluminum oxide and SiO2 nanoparticles can effectively improve the hardness of the coating without affecting the adhesion between the coating and the adherend.

The two guide strips 24 are movably embedded in the two guide notches 222 on each mixing plate 22.

[0040] A threaded hole 223 is formed in each mixing plate 22 , a screw rod 225 is inserted into the uppermost threaded hole 223 , and a pull ring 2251 is formed at the end of the screw rod 225 .

[0041] A driven gear 13 is also fixed concentrically to one end of the moving tube 141 close to the reduction motor 12 . Correspondingly, a driving gear 16 is also fixed concentrically to the rotating shaft of the reduction motor 12 and meshes with the driven gear 13 .

[0042] A bracket 15 and an end block 17 are fixed to the left and right outer walls of the lower box body 11 , respectively. Two ends of the fixed shaft 142 are fixed to the bracket 15 and the end block 17 , respectively. The driven gear 13 is arranged inside the bracket 15 .

[0043] Working principle:

[0044] All the formula materials constituting the water-based UV resin are poured into the upper mixing plate 22 located at the top of the upper box 21 through the top opening of the upper box 21, so as to make the various formula materials preliminarily mixed with each other; then, after flowing through each spiral mixing channel 23, the mixed material will pass through the cavity 211 and enter the lower box 11 through the top opening of the lower box 11. In the above process, the mixed material is divided into a corresponding number of tributaries according to the number of spiral mixing channels 23, and each tributary flows downward along the trajectory of the spiral mixing channel 23, thereby extending the flow path and time of each mixed material tributary to allow the materials to be fully mixed, and avoiding excessive flow and flow rate of the mixed material entering the lower box 11.

[0045] The reduction motor 12 is started to rotate its rotating shaft, and then the plurality of stirring units 143 are driven to rotate by means of the moving tube 141 in the stirring body 14, so that the stirring shaft 1431 in each stirring unit 143 is used to stir the mixed material in the lower box 11 in a revolving manner.

[0046] During the above process, the fixed shaft 142 is always fixed, and the stirring shaft 1431 will rotate around the fixed shaft 142. Since the bevel gear ring 14311 located at the root of the stirring shaft 1431 is engaged with the annular bevel gear surface 14331 on the fixed plate 1433, the stirring shaft 1431 will rotate while rotating around the fixed shaft 142, and then the mixed material located in the lower box body 11 will be stirred by the stirring block 1432 in a self-rotating manner. The simultaneous effects of orbital stirring and self-rotation stirring can greatly improve the mixing uniformity of the mixed material.

[0047] If the length of each spiral mixing channel 23 is to be changed, the number of mixing plates 22 can be increased or decreased from top to bottom, which is flexible and convenient to use; when taking out the mixing plate 22, just hook the pull ring 2251 with your hand or a tool, and then pull the mixing plate 22 vertically upward until it leaves the upper box body 21, then rotate the pull ring 2251 to unscrew the screw 225 from the threaded hole 223 on the mixing plate 22, and then screw it into the threaded hole 223 on the mixing plate 22 located at the top of the upper box body 21 at this time, thereby preventing the mixed material from falling into the lower box body 11 through the threaded hole 223 on each mixing plate 22, and so on; the mutual cooperation between the two guide strips 24 and the two guide notches 222 on each mixing plate 22 can prevent the mixing plate 22 from shifting laterally, thereby ensuring that the spiral mixing channel 23 can be accurately combined and connected, and ensuring the stable flow rate of the mixed material flowing through.

[0048] To disassemble the stirring shaft 1431, first separate the two seat blocks 1435 from each other, then pull the stirring shaft 1431 and the seat block 1435 on which the stirring shaft 1431 is located outward in a direction perpendicular to the central axis of the fixed shaft 142, and then slide the stirring shaft 1431 outward along the inner wall of the sealing sleeve 1434, so that the bevel gear ring 14311 at the root of the stirring shaft 1431 can be pulled out of the sealing sleeve 1434. To install the stirring shaft 1431, simply perform the above-mentioned operation in reverse.

[0049] The present invention adopts a lateral stirring method to be suitable for water-based UV resins with lower viscosity, thereby accelerating the stirring speed and improving the stirring efficiency; the various formula materials are first preliminarily mixed with the help of the mixing component 2, and then finely mixed with the help of the stirring body 14, and the stirring body 14 adopts a combination of rotation and orbital rotation, thereby increasing and optimizing the stirring mode, thereby greatly improving the mixing effect of each formula material and significantly improving the uniformity of the mixed material.
