[0020] The utility model is described in detail below in conjunction with the accompanying drawings.

[0021] Reference Figure 1-Figure 3 , an acrylic resin raw material dispersing device, comprising a stirring tank 1, a partition 2 is arranged on the upper part of the stirring tank 1, the edge of the partition 2 is fixedly connected to the inner wall of the stirring tank 1, and the interior of the stirring tank 1 is divided into a first chamber 3 and a second chamber 4 from top to bottom, a mounting groove is opened at the center of the partition 2, a mounting seat is fixedly arranged in the mounting groove, a universal ball 5 is embedded in the mounting seat, and a movable rod 6 is fixedly passed through the center of the universal ball 5;

[0022] A first rectangular frame 7 is slidably connected in the first chamber 3, and a second rectangular frame 8 is slidably connected below the first rectangular frame 7. The sliding direction of the first rectangular frame 7 is perpendicular to the sliding direction of the second rectangular frame 8. A driving mechanism for driving the first rectangular frame 7 and the second rectangular frame 8 to slide in sequence is provided in the first chamber 3;

[0023] The upper end of the movable rod 6 extends to the inner side of the first rectangular frame 7 and the second rectangular frame 8, and the outer wall of the movable rod 6 fits with the inner walls of both sides of the first rectangular frame 7 and the second rectangular frame 8. The lower end of the movable rod 6 extends into the second chamber 4 and is fixed with a base 9. A first motor is fixed in the base 9. A stirring shaft 10 is transmission-connected to the output shaft of the first motor, and a plurality of stirring rods 11 are fixed on the stirring shaft 10.

[0024] The driving mechanism includes two reciprocating screw rods 12 rotatably connected to the inner wall of the first chamber 3. The two reciprocating screw rods 12 extend along the sliding directions of the first rectangular frame 7 and the second rectangular frame 8 respectively. A fixed block 13 is fixed on the first rectangular frame 7 and the second rectangular frame 8. The reciprocating screw rod 12 passes through the fixed block 13 and cooperates with its thread. A second motor for driving the reciprocating screw rod 12 to rotate is fixed on the outside of the mixing tank 1.

[0025] Two slide rails 14 are fixedly connected to the inner wall of the first chamber 3, and the two slide rails 14 are respectively parallel to the two reciprocating screws 12. A slider 15 is fixedly provided on the side of the first rectangular frame 7 and the second rectangular frame 8 away from the fixed block 13. The slider 15 is located in the slide rail 14 and slidably cooperates with the slider 14, and the slide rail 14 is fixedly provided with limit blocks 16 for contacting the slider 15 on both sides of the slider 15. The reciprocating motion stroke of the slider 15 is limited by the limit blocks 16, which is more precise and prevents the stirring rod 11 from continuously tilting and contacting the inner wall of the second chamber 4.

[0026] The stirring rods 11 are generally in a C-shaped structure that is longer at the top and shorter at the bottom. To match the movement trajectory of the stirring shaft 10, the stirring rods 11 are configured to be C-shaped that is longer at the top and shorter at the bottom to match it. This allows the stirring rods 11 to fully contact the raw materials at the edge of the second chamber 4 while preventing the stirring rods 11 from hitting the inner wall of the second chamber 4 and causing damage.

[0027] A plurality of feed pipes 17 are circumferentially arranged on the side wall of the second chamber 4 , a discharge pipe 18 is arranged at the bottom of the second chamber 4 , and a valve for controlling the opening and closing of the discharge port is arranged on the discharge pipe 18 .

[0028] Working principle: When in use, the raw materials for producing acrylic resin are added into the second chamber 4 through the feed pipe 17, and then the first motor is started. The first motor drives the stirring shaft 10 to rotate, and then drives multiple stirring rods 11 to stir the materials. At the same time, the driving mechanism drives the first rectangular frame 7 and the second rectangular frame 8 to slide in sequence. When the first rectangular frame 7 slides, the inner wall of the first rectangular frame 7 will push the upper end of the movable rod 6, and the second rectangular frame 8 provides space for the movable rod 6 to move. Through the flexible rotation of the universal ball 5, the lower end of the movable rod 6 will drive the stirring shaft 10 to tilt at a certain angle in the second chamber 4, so that the stirring shaft 10 rotates and swings to stir the materials. Similarly, when the second rectangular frame 8 slides, the stirring shaft 10 rotates and swings in a perpendicular direction to stir the materials, so that the stirring direction is diversified, avoiding uneven stirring caused by a single stirring direction, and improving the material dispersion effect. After mixing is completed, open the valve on the discharge pipe 18 to discharge the material from the mixing tank 1.

[0029] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
