[0029] Specifically, the raw materials to be mixed are added into the raw material box 7, and then the raw materials are quantitatively extracted with the cooperation of the feeding component 9, and are accurately delivered to the mixing device through the feeding trough 16, thereby achieving uniform stirring and mixing of the n-butyl methacrylate raw materials. Then, the motor 11 is started to drive the rotation of the stirring shaft 14, and the rotation of the stirring shaft 14 drives the rotation of the first-stage gear 13. Then, under the action of the engagement of the first-stage gear 13 and the second-stage gear 15, the rotation of the second-stage gear 15 is driven, and the rotation of the stirring shaft 14 is driven, thereby achieving sufficient stirring of the raw materials inside the mixing device.

A spring 603 is fixedly arranged on the lower end surface of the fixed plate and the other end of the spring 603 is fixedly connected to the side opposite to the upper end surface of the moving block 601. The center of the lower end surface of the moving block 601 An adjusting rod 604 is fixedly provided, and a first-level limiting rod 605 is hingedly provided at the center position of the front and rear end surfaces of the outer wall of the adjusting rod 604.

The two second-level limiting rods 607 are both movably clamped in the two limiting grooves 17.

[0031] Specifically, when it is necessary to clean the stirring shaft 14 inside the device, the pull rod 602 is pulled to drive the adjusting rod 604 on the lower end face of the moving block 601 to move, and the movement of the adjusting rod 604 drives the first-level limiting rod 605 hingedly set on the front and rear end faces of the outer wall to move relative to each other, and then the two second-level limiting rods 607 hingedly set are driven to retract under the relative movement of the two first-level limiting rods 605, and then disengage from the two limiting grooves 17 that are movably engaged with the inner wall of the mixing device. During this process, one side of the outer wall of the second-level limiting rod 607 is movably connected to the inner wall of the limiting block 606, ensuring its precise movement, so that the stirring shaft 14 together with the sealing cover 4 can be easily removed, which facilitates the convenient disassembly and cleaning and maintenance of the stirring shaft 14, and further improves the service life of the device.

[0032] The feeding assembly 9 includes a sleeve 901 and a rotating rod 907. A through slot 902 is provided on one side of the outer wall of the sleeve 901. Fixed slots 903 are provided at the lower end positions of the front and rear end surfaces of the outer wall of the sleeve 901. A rotating block 904 is provided for rotation in the sleeve 901. A notch 905 is provided at one side position of the lower end surface of the rotating block 904. The rotating rod 907 is fixedly arranged at the center of the upper end surface of the rotating block 904. A bearing 906 is fixedly sleeved on the outer wall of the rotating rod 907 near the rotating block 904, and the bearing 906 is fixedly sleeved on the upper end position of the inner wall of the sleeve 901. A through slot 908 is provided through the bottom end surface of the inner wall of the sleeve 901 near one side. A through slot 10 is provided through the lower end surface of the inner wall of the raw material box 7 and is located at the lower end position of the No. 2 through slot 908. A fixing mechanism 8 is provided on the lower end surface of the inner wall of the raw material box 7 and near the side position of the sleeve 901.

[0033] Specifically, the operator rotates rotating rod 907, driving rotation of rotating block 904. Consequently, notch 905 on rotating block 904 cooperates with slot 1 902 on sleeve 901 to achieve quantitative extraction of the raw material. When rotating block 904 aligns with slot 1 902 on sleeve 901, the raw material flows along slot 902 into notch 905. Continued rotation of rotating block 904 then precisely delivers the raw material in notch 905 through feed chute 16 into the mixing device, achieving uniform stirring and mixing of the n-butyl methacrylate raw material.

[0034] The fixing mechanism 8 includes a fixing box 801, a threaded rod 802 and two fixing blocks 806. The threaded rod 802 is rotatably set at the center of the front and rear end surfaces of the inner wall of the fixing box 801. A rotating handle 803 is fixedly set on the front end surface of the threaded rod 802. A sliding groove 804 is opened at the center of one side of the fixing box 801. The outer wall of the threaded rod 802 is threaded with fixing rods 805 at the front and rear end positions. The two fixing blocks 806 are fixedly set at the opposite side of the two fixing rods 805, and the two fixing blocks 806 are movably connected in the two fixing grooves 903.

[0035] Specifically, when it is necessary to replace the feeding assembly 9 of different specifications or capacity, the rotating handle 803 is rotated to drive the threaded rod 802 to rotate, and then the two fixing rods 805 are driven to move apart under the rotation of the threaded rod 802, and then the two fixing blocks 806 are driven to disengage from the fixing grooves 903 on the outer wall of the sleeve 901, so as to achieve the replacement and cleaning of the feeding assembly 9. When the replacement is completed, the rotating handle 803 is rotated in the opposite direction, so that the two fixing rods 805 are driven to move relative to each other under the rotation of the threaded rod 802, and then the two fixing blocks 806 are driven to snap into the fixing grooves 903, so as to achieve the installation and fixation of the feeding assembly 9. Through the convenient disassembly design, the operator can replace the quantitative feeding assembly 9 of different capacities and models according to production needs to meet different production needs. It has high flexibility and adaptability, and the replacement process is simple and fast, which reduces downtime and greatly improves feeding efficiency.

[0036] Working principle: The operator first rotates the rotary handle 803, and through the cooperation of the fixing mechanism 8, the feeding component 9 is replaced with a different specification or capacity. After the replacement is completed, the required mixed raw materials are then added to the raw material box 7. With the cooperation of the feeding component 9, the raw materials are quantitatively extracted and accurately delivered to the mixing device through the feeding trough 16, thereby achieving uniform stirring and mixing of the n-butyl methacrylate raw materials. Then, the motor 11 is started, which drives the stirring shaft 14 to fully stir the raw materials inside the device.

[0037] Secondly, when the internal stirring shaft 14 needs to be maintained and cleaned, the pull rod 602 is pulled, and then with the cooperation of the limiting mechanism 6, the stirring shaft 14 can be easily taken out, which facilitates the convenient disassembly and cleaning and maintenance of the stirring shaft 14, further improving the service life of the device.
