Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of gypsum board production, in particular to an automatic additive adding machine for auxiliary materials in a gypsum board production line. Background Art
[0002] During the production of gypsum boards, a certain amount of auxiliary materials need to be added. The traditional operation of adding dry materials with wet methods is rather cumbersome. During the production process, after manual weighing, they need to be added to the mixing tank. The labor intensity of workers is high, the operation deviation is large, which is not conducive to accurate material control, and the degree of automation is low.
[0003] The Chinese patent discloses a weighing screw conveyor batching device (authorization announcement number CN216704236U). This patented technology measures the total weight of the screw conveyor and the auxiliary materials during the production process of gypsum boards in real time through a weight sensor, so as to obtain the weight of the auxiliary materials conveyed by the screw conveyor, which is convenient to set through the controller according to the weight of the auxiliary materials to be added. After the screw conveyor is started, it stops after reaching the set weight value. This device fully realizes automatic batching, with accurate proportioning, reduces the manual operation link, avoids deviation, is convenient for adjustment and control, reduces the labor intensity, and improves the automation level of the production line;
[0004] However, it has certain drawbacks: it can only convey the auxiliary materials and cannot perform crushing and refining treatment on the auxiliary materials. This makes it easy for the auxiliary materials with larger particle sizes to agglomerate when mixed with water or other raw materials, resulting in poor mixing uniformity, and further affecting the final quality and performance of the gypsum board. Summary of the Utility Model

Two second motors are symmetrically installed on the left surface of the feed hopper. Auxiliary material crushing rollers are installed at the output ends of the two second motors. A screening mechanism is jointly arranged below the two auxiliary material crushing rollers inside the feed hopper.

Specific implementation mode
[0021] Please refer to Figure 1 and Figure 2 In the embodiment of the present utility model, an automatic additive machine for auxiliary materials in a gypsum board production line includes an auxiliary material conveying cylinder 1. A first motor 2 is installed on the left side surface of the auxiliary material conveying cylinder 1. The output end of the first motor 2 is installed with a spiral tube 3. The spiral tube 3 is located inside the auxiliary material conveying cylinder 1, and the right end of the spiral tube 3 is rotatably connected to the right side surface inside the auxiliary material conveying cylinder 1. The right end of the lower surface of the auxiliary material conveying cylinder 1 is penetrated and connected with a discharge pipe 4, and the left end of the upper surface of the auxiliary material conveying cylinder 1 is penetrated and connected with a feed hopper 5. Two second motors 6 are symmetrically installed on the left side surface of the feed hopper 5. The output ends of the two second motors 6 are both installed with auxiliary material crushing rollers 7. The auxiliary material crushing rollers 7 are located inside the feed hopper 5, and the right ends of the auxiliary material crushing rollers 7 are rotatably connected to the right side surface inside the feed hopper 5. A floor scale 17 is installed on the lower surface of the auxiliary material conveying cylinder 1 on the left side of the discharge pipe 4;
[0022] The feed hopper 5 is used for discharging gypsum board auxiliary materials;
[0023] The first motor 2 drives the spiral tube 3 to rotate, which is used for conveying gypsum board auxiliary materials;
[0024] One of the two first motors 2 rotates forward and the other rotates reversely, both rotating towards the middle direction;
[0025] The second motor 6 drives the auxiliary material crushing roller 7 to rotate, which is used for crushing the auxiliary materials, refining the auxiliary materials, so that the subsequent auxiliary materials can be quickly mixed with water;
[0026] The floor scale 17 is used for weighing the transported gypsum board auxiliary materials, ensuring the accurate addition of the auxiliary materials. The floor scale 17 first detects the total weight. When the reduced weight reaches the required added weight, the external control system controls the first motor 2 to stop running.
[0027] In Figure 2 and Figure 3In the middle: Inside the feed hopper 5, a screening mechanism 8 is jointly arranged below the two auxiliary material crushing rollers 7. The screening mechanism 8 includes a screening plate 9. The screening plate 9 is movably attached to the inner surface of the feed hopper 5. At the four corners of the screening plate 9, support rods 10 are movably penetrated. At the lower end of the support rod 10, a first support block 11 is installed, and at the upper end of the support rod 10, a second support block 12 is installed. One end of the first support block 11 and the second support block 12 are both installed on the inner side surface of the feed hopper 5;
[0028] The second support block 12 is very close to the auxiliary material crushing roller 7, but does not contact it;
[0029] The screening plate 9 is used to filter the incompletely crushed materials.
[0030] In Figures 2 to 4 In the middle: On the left and right side surfaces inside the feed hopper 5, below the screening mechanism 8, a knocking mechanism 13 is arranged. The knocking mechanism 13 includes a support plate 14. One end of the support plate 14 is installed on the inner side surface of the feed hopper 5. On the rear surface of the support plate 14, a third motor 15 is installed. The output end of the third motor 15 is installed with a cam 16. The cam 16 is located on the front side of the support plate 14;
[0031] When the convex end of the cam 16 rotates to the uppermost position, the screening plate 9 can be quickly pushed to the uppermost position. At this time, the screening plate 9 is very close to the second support block 12, but does not contact it. Through the inertia when the screening plate 9 rises, the incompletely crushed auxiliary materials are driven to contact the auxiliary material crushing roller 7 for further crushing, and the crushed auxiliary materials can pass through quickly;
[0032] One of the two cams 16 rotates counterclockwise and the other rotates clockwise, so as to push the screening plate 9 simultaneously.
[0033] The working principle of the present utility model is as follows: When in use, the gypsum board auxiliary materials are put into the feed hopper 5, and the platform scale 17 detects the total weight; after the auxiliary materials fall into the feed hopper 5, the second motor 6 drives the auxiliary material crushing roller 7 to rotate to crush the auxiliary materials. The crushed auxiliary materials fall onto the surface of the screening plate 9, and the incompletely crushed auxiliary materials will be blocked; the third motor 15 drives the cam 16 to rotate and continuously push the screening plate 9 upward, so that the incompletely screened auxiliary materials on the surface of the screening plate 9 are swung to contact the auxiliary material crushing roller 7 for further crushing. The crushed auxiliary materials fall into the auxiliary material conveying cylinder 1, the first motor 2 drives the spiral tube 3 to rotate to drive the auxiliary materials to move to the right, and finally are discharged through the discharge pipe 4. When the reduced weight reaches the required added weight, the first motor 2 stops running.
[0034] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
