Description

Technical Field

[0001] The utility model relates to the technical field of batching devices, in particular to an automatic batching device for gypsum board raw materials. Background Art

[0002] Gypsum board is generally composed of a mixture of multiple powders, and then water and foaming agent are added. The powders need to be mixed evenly before adding water, otherwise the powders will become milky after adding water, making it more difficult to mix evenly, which will ultimately affect the strength of the gypsum board.

[0003] Existing batching machines generally consist of a mixing barrel and a stirring rod extending into the mixing barrel. The mixing barrel is provided with a plurality of feeding ports for adding raw materials. The stirring rod mixes the powder evenly and then discharges it, as shown in a Chinese utility model patent with publication number CN215586127U, entitled A batching barrel for soil fertilizer.

[0004] The disadvantage of this mixer is that the materials of each component are concentrated together after entering the mixing barrel. If you want to mix all the materials evenly, the stirring rod needs to run for a long time; when the mixing barrel is large, the stirring rod needs to run for a longer time. In order to achieve the purpose of quickly mixing the materials evenly, the existing batching barrels are mostly improved in the structure of the stirring rod. Utility Model Content

DETAILED DESCRIPTION

[0024] The following is combined with Figure 1 To Attachment Figure 4 The principles and features of the present invention are described, and the examples given are only used to explain the present invention, and are not used to limit the scope of the present invention.

[0025] A gypsum board raw material automatic batching device comprises a batching barrel 1, a stirring rod 4 and a return material auger 6.

[0026] The batching barrel 1 is provided with an opening facing upward, and a pressure cover 12 is added at the opening. A plurality of feed ports 2 are provided on the top of the batching barrel 1 (i.e., on the pressure cover 12), and the plurality of feed ports 2 are arranged in an array along the circumferential direction, and each feed port 2 corresponds to a material. A discharge port 3 for discharging materials is provided at the bottom of the batching barrel 1. One end of the stirring rod 4 extends into the batching barrel 1 for stirring the materials, and the other end of the stirring rod 4 extends out of the batching barrel 1 and is connected to the first driving mechanism 5, and the first driving mechanism 5 is used to drive the stirring rod 4 to rotate. A return material chamber 7 is provided in the batching barrel 1, and the bottom of the return material chamber 7 is connected to the bottom of the batching barrel 1, and a return material port 8 is provided at the top of the return material chamber 7, and the return material auger 6 is rotatably connected to the return material chamber 7. The material can be uploaded from the bottom of the batching barrel 1 to the top of the batching barrel 1 through the return material chamber 7.

[0027] The return material chamber 7 is formed by the following structure. The batching barrel 1 includes an outer wall 10 and an inner wall 11, and a partition plate 13 is arranged between the outer wall 10 and the inner wall 11, and the partition plate 13 divides the chamber between the outer wall 10 and the inner wall 11 to form the return material chamber 7, and the number of the return material chambers 7 is the same as the number of the return material augers 6, and each return material chamber 7 is provided with a stirring rod 4.

[0028] The top of the return auger 6 extends out of the batching barrel 1 and is connected to the second drive mechanism 9. The first drive mechanism 5 and the second drive mechanism 9 are connected to each other through a power connection mechanism 17. The first drive mechanism 5 includes a motor 18 and a reducer 19. The output end of the motor 18 is connected to the input end of the reducer 19. The reducer 19 has two output ends, one of which is connected to the stirring rod 4. Under the action of the power connection mechanism 17, the motor 18 can simultaneously drive the stirring rod 4 and the return auger 6 to rotate simultaneously. Specifically, the second drive mechanism 9 includes a synchronous belt 14, a synchronous pulley 15 and a power wheel 16. One end of the return auger 6 extending out of the batching barrel 1 is connected to the synchronous pulley 15, all the synchronous pulleys 15 are connected and driven by the synchronous belt 14, and the power wheel 16 is meshed with the synchronous belt 14 for transmission. The power wheel 16 is used as the main power source to drive the synchronous belt 14 to rotate. The rotation of the synchronous belt 14 drives all the synchronous pulleys 15 to rotate and then drives the return auger 6 to rotate. The power connection mechanism 17 includes a clutch 20, a first commutator 21, a second commutator 22, a first connecting shaft 23 and a second connecting shaft 24. The first commutator 21 and the second commutator 22 are connected to the batching barrel 1. One end of the first connecting shaft 23 is connected to one side of the clutch 20, and the other end of the first connecting shaft 23 is connected to the output end of the first commutator 21. The input end of the first commutator 21 is connected to the output end of the reducer 19; one end of the second connecting shaft 24 is connected to the other side of the clutch 20, and the other end of the second connecting shaft 24 is connected to the input end of the second commutator 22, and the output end of the second commutator 22 is connected to the power wheel 16. When the clutches 20 are mutually attracted, the motor 18 can simultaneously drive the stirring rod 4 and all the return auger 6 to rotate; when the clutch 20 is not attracted, the motor 18 only drives the stirring rod 4 to rotate.

[0029] When the material returns from the bottom of the batching barrel 1 to the upper part of the batching barrel 1 through the return cavity 7, dust will be generated. Therefore, a negative pressure port 25 is provided on the batching barrel 1. The negative pressure port 25 can absorb the dust generated in this process and recycle it through the dust bag cage.

[0030] The device is provided with a return material chamber 7 and a return material auger 6 in the batching barrel 1, which can cooperate with the stirring rod 4 to complete the mixing of materials more quickly.

[0031] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
