Description

Technical Field

[0001] This invention relates to the field of gypsum board raw material production technology, and specifically to a gypsum board raw material mixing device. Background Technology

[0002] In the production of gypsum board, the mixing of raw materials is a crucial step. The quality, strength, and performance of the gypsum board are directly related to the effectiveness of the mixing process. To ensure the quality of gypsum board, it is usually necessary to uniformly mix gypsum powder, additives, fibers, and other auxiliary materials during production. However, currently common gypsum board raw material mixing equipment has the following shortcomings in practical use:

[0003] 1. Traditional gypsum board raw material mixing equipment typically employs a single mixing structure, such as a single-shaft mixer or ribbon mixer. While these devices can perform basic mixing tasks, their mixing efficiency is low due to design limitations. They cannot quickly achieve the required uniformity, especially when dealing with raw materials with high viscosity or containing particulate matter. The mixing effect of traditional equipment becomes inadequate, resulting in incomplete uniformity of the raw materials during the mixing process, which may affect the quality of the gypsum board.

[0004] 2. Currently, most mixing equipment has a fixed integrated design for its mixing system and mixing tank. This greatly reduces the flexibility and operability of the equipment in actual use. Gypsum raw materials usually contain a certain amount of moisture and sticky substances. These substances are easy to adhere to the surfaces of the mixing equipment such as the mixing blades and tank walls. The integrated design of the mixing system and mixing tank makes it difficult to clean, which can easily lead to the accumulation of equipment residues, thereby affecting the operating efficiency of the equipment and may even cause cross-contamination, affecting the production quality of subsequent batches. Summary of the Invention

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a gypsum board raw material mixing device, which can effectively solve the problems that the existing gypsum board raw material mixing devices usually adopt a single mixing structure and that the stirring system and mixing tank of most current mixing devices are usually designed as a fixed integrated unit, which greatly reduces the flexibility and operability of the equipment in actual use.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] This invention provides a gypsum board raw material mixing device, including a base, two upright plates symmetrically fixedly connected to the upper end of the base, a support plate fixedly connected to the upper end of the two upright plates, a mixing tank rotatably connected to the upper end of the support plate, a plurality of guide holes opened in the support plate, a guide rod slidably connected to each guide hole, the lower ends of the plurality of guide rods abutting against the upper end of the base, a top plate fixedly connected to the upper end of the plurality of guide rods, and a stirring assembly provided on the upper end of the top plate;

[0008] The stirring assembly includes multiple support frames fixedly connected to the upper end of a support plate, and all support frames are L-shaped. The other ends of the multiple support frames are fixedly connected to a mounting box. An upper driven bevel gear and a lower driven bevel gear are rotatably connected to the inner top wall and inner bottom wall of the mounting box, respectively. A rotary motor is rotatably mounted on the inner side wall of the mounting box. A driving bevel gear is coaxially fixedly connected to the output end of the rotary motor. The driving bevel gear meshes with the upper driven bevel gear and the lower driven bevel gear. A connecting cylinder passing through the bottom wall of the mounting box is coaxially fixedly connected to the lower end of the lower driven bevel gear. A cover plate is coaxially fixedly connected to the lower end of the connecting cylinder. A rotating groove is opened on the top plate, and the cover plate is rotatably connected to the rotating groove. A stirring shaft is coaxially fixedly connected to the lower end of the upper driven bevel gear. The lower end of the stirring shaft extends into the interior of the mixing tank, and multiple stirring plates are fixedly connected to the shaft of the mixing tank.

[0009] According to the above-mentioned gypsum board raw material mixing equipment, a limiting groove is provided at the upper end of the support plate, and the limiting groove is wider at the top and narrower at the bottom. The mixing barrel is rotatably connected to the limiting groove.

[0010] According to the above-mentioned gypsum board raw material mixing equipment, two positioning holes are symmetrically opened at the upper end of the mixing barrel, and two positioning blocks that are inserted and matched with the positioning holes are symmetrically fixedly connected at the lower end of the cover plate, and the top view projection of the cover plate covers the top view projection of the mixing barrel.

[0011] According to the above-mentioned gypsum board raw material mixing equipment, each of the multiple mixing plates has multiple turbulence holes.

[0012] According to the above-mentioned gypsum board raw material mixing equipment, the lower driven bevel gear has a clearance hole, and the lower end of the stirring shaft passes through the clearance hole and the bottom wall of the mounting box from top to bottom.

[0013] According to the above-mentioned gypsum board raw material mixing equipment, a guide groove is provided at the upper end of the base between two vertical plates, and a collection box is slidably connected to the guide groove.

[0014] According to the above-mentioned gypsum board raw material mixing equipment, the lower end of the mixing barrel is connected to a feeding pipe, and the lower end of the mixing barrel is also equipped with a solenoid valve for controlling the feeding of the feeding pipe, and the collection box is located directly below the feeding pipe.

[0015] The technical solution provided by this invention has the following advantages compared with the known prior art:

[0016] 1. In this invention, the stirring shaft drives the stirring plate to rotate, stirring the raw materials. The reverse rotation of the mixing drum causes the raw materials to convect within the mixing drum. Compared with traditional single-structure mixing equipment, this greatly improves the mixing efficiency, meets the production line's demand for rapid mixing of gypsum board raw materials, allows the raw materials to be mixed more thoroughly, improves the uniformity of mixing, and ensures the quality of gypsum board. The turbulence holes on the stirring plate increase the mixing effect between materials, further enhancing the overall mixing effect.

[0017] 2. The mixing component and mixing tank of this invention are not a fixed integrated design. During equipment cleaning, the mixing component and mixing tank can be easily separated, facilitating individual cleaning of each component. This reduces the accumulation of residue on the equipment, avoids cross-contamination, ensures the production quality of subsequent batches, extends the service life of the equipment, and reduces maintenance costs.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0026] The present invention will be further described below with reference to embodiments.

[0027] Example: Refer to Figures 1 to 5 A gypsum board raw material mixing device includes a base 1, two upright plates 2 are symmetrically fixedly connected to the upper end of the base 1, a support plate 3 is fixedly connected to the upper end of the two upright plates 2, a mixing tank 17 is rotatably connected to the upper end of the support plate 3, a guide groove 21 is opened between the two upright plates 2 at the upper end of the base 1, and a collection box 22 is slidably connected to the guide groove 21. The collection box 22 is used to receive the mixed gypsum board raw material, which facilitates the subsequent processing and use of the gypsum board raw material.

[0028] The lower end of the mixing tank 17 is connected to a feeding pipe. A solenoid valve for controlling the feeding of materials through the feeding pipe is also installed at the lower end of the mixing tank 17. The collection box 22 is located directly below the feeding pipe. When the raw materials are mixed to the required uniformity, the stirring component stops working. Then, the solenoid valve installed at the lower end of the mixing tank 17 is opened, and the mixed raw materials fall into the collection box 22 below through the feeding pipe, completing the discharge process. The collection box 22 can be easily removed along the guide groove 21 for subsequent processing of the mixed raw materials.

[0029] A limiting groove 31 is provided at the upper end of the support plate 3, and the limiting groove 31 is wider at the top and narrower at the bottom. The mixing barrel 17 is rotatably connected to the limiting groove 31. The mixing barrel 17 is rotatably supported by the limiting groove 31 on the support plate 3, and the mixing barrel 17 is rotatably connected to the limiting groove 31 to ensure that the mixing barrel 17 can rotate stably.

[0030] The support plate 3 has multiple guide holes 4, and each guide hole 4 is slidably connected to a guide rod 5. The lower ends of the multiple guide rods 5 abut against the upper end of the base 1, and the upper ends of the multiple guide rods 5 are fixedly connected to a top plate 6. The guide rods 5 pass through the guide holes 4 on the support plate 3 and are fixedly connected to the top plate 6 at their upper ends, thus playing a guiding and supporting role for the top plate 6 and ensuring the stability of the top plate 6 during subsequent movement.

[0031] Multiple guide rods 5 are provided, as well as multiple guide holes 4 for sliding the guide rods 5. The guide rods 5 can slide in the vertical direction of the guide holes 4, which facilitates the separation of the stirring component and the mixing tank 17, simplifies the operation, and changes the previous integrated design of the mixing tank 17 and the stirring component.

[0032] A stirring assembly is provided at the upper end of the top plate 6. Specifically, the stirring assembly includes multiple support frames 7 fixedly connected to the upper end of the support plate 3, and the multiple support frames 7 are all L-shaped. The other ends of the multiple support frames 7 are fixedly connected to a mounting box 8. The upper driven bevel gear 9 and the lower driven bevel gear 10 are rotatably connected to the inner top wall and inner bottom wall of the mounting box 8, respectively. A rotary motor 12 is rotatably installed on the inner side wall of the mounting box 8. The output end of the rotary motor 12 is coaxially fixedly connected to a driving bevel gear 11. The driving bevel gear 11 meshes with the upper driven bevel gear 9 and the lower driven bevel gear 10. The rotary motor 12 drives the driving bevel gear 11 to rotate. Since the driving bevel gear 11 meshes with the upper driven bevel gear 9 and the lower driven bevel gear 10, the rotation of the driving bevel gear 11 will drive the upper driven bevel gear 9 and the lower driven bevel gear 10 to rotate simultaneously, and the rotation directions of the upper driven bevel gear 9 and the lower driven bevel gear 10 are opposite.

[0033] The lower driven bevel gear 10 is coaxially fixedly connected to a connecting cylinder 13 that passes through the bottom wall of the mounting box 8. The lower end of the connecting cylinder 13 is coaxially fixedly connected to a cover plate 14. The upper end of the mixing tank 17 has two symmetrically opened positioning holes 171. The lower end of the cover plate 14 is symmetrically fixedly connected to two positioning blocks 16 that are inserted into the positioning holes 171. When the lower driven bevel gear 10 rotates, it drives the connecting cylinder 13, which is coaxially fixedly connected to it, to rotate. The cover plate 14, which is coaxially fixedly connected to the lower end of the connecting cylinder 13, will also rotate accordingly. Since the positioning blocks 16 at the lower end of the cover plate 14 are inserted into the positioning holes 171 at the upper end of the mixing tank 17, the mixing tank 17 is driven to rotate. The rotation direction of the mixing tank 17 is opposite to that of the stirring shaft 18. The cover plate 14 is rotatably connected to the rotating groove 15 on the top plate 6. This not only ensures the stability of the rotation of the cover plate 14, but also makes the stirring assembly more stable during operation.

[0034] The top view projection of the cover plate 14 covers the top view projection of the mixing tank 17, which can prevent the raw materials from overflowing from the top of the mixing tank 17 during the mixing process and play a sealing role.

[0035] The top plate 6 has a rotating groove 15, and the cover plate 14 is rotatably connected to the rotating groove 15. The lower end of the upper driven bevel gear 9 is coaxially fixedly connected to the stirring shaft 18. The lower end of the stirring shaft 18 extends into the interior of the mixing tank 17, and multiple stirring plates 19 are fixedly connected to the shaft of the mixing tank 17. The lower driven bevel gear 10 has a clearance hole. The lower end of the stirring shaft 18 passes through the clearance hole and the bottom wall of the mounting box 8 from top to bottom. When the upper driven bevel gear 9 rotates, it drives the stirring shaft 18, which is coaxially fixedly connected to it, to rotate. The lower end of the stirring shaft 18 extends into the interior of the mixing tank 17. The rotation of the stirring shaft 18 causes the multiple stirring plates 19 fixedly connected to the shaft of the mixing tank 17 to rotate accordingly, thereby stirring and mixing the gypsum board raw materials in the mixing tank 17.

[0036] Since the mixing assembly and the mixing tank 17 are not fixed as a single unit, when the equipment needs to be cleaned, multiple guide rods 5 can be slid upward along the guide holes 4 by using the upward sleeve top plate 6, so that the cover plate 14 is separated from the mixing tank 17 (the positioning block 16 is pulled out from the positioning hole 171). This makes it convenient to clean the inside of the mixing tank 17, the mixing plate 19, and the cover plate 14 one by one, reducing the accumulation of equipment residues, avoiding cross-contamination, and ensuring the production quality of subsequent batches.

[0037] While the mixing assembly is working, because the mixing tank 17 is rotatably connected to the support plate 3, under the force generated by the mixing plate 19 stirring the raw materials and the influence of the mixing assembly's own operation, the mixing tank 17 will rotate around its own axis in the opposite direction to the mixing shaft 18. The reverse rotation of the mixing tank 17 further enhances the mixing effect of the raw materials, allowing the raw materials to tumble and mix more fully in the mixing tank 17, improving the uniformity of mixing, and improving the efficiency of mixing gypsum edge raw materials.

[0038] Multiple mixing plates 19 are each provided with multiple turbulence holes 20. The multiple turbulence holes 20 on the mixing plates 19 can change the flow state of the materials during mixing, increase the mixing effect between the materials, make the raw materials more uniformly mixed, and increase the mixing effect of the gypsum board raw materials.

[0039] The specific working principle of this invention:

[0040] Place the mixing bucket 17 on the limiting groove 31 of the support plate 3, pass the guide rod 5 through the guide hole 4 on the support plate 3, so that the lower end of the guide rod 5 abuts against the base 1. At this time, the cover plate 14 covers the upper end of the mixing bucket 17, and the two positioning blocks 16 are inserted downward into the two positioning holes 171 at the upper end of the mixing bucket 17. Then add the gypsum board raw material to be mixed into the mixing bucket 17.

[0041] The rotary motor 12 is started, which drives the active bevel gear 11 to rotate. The active bevel gear 11 meshes with the upper driven bevel gear 9 and the lower driven bevel gear 10, thereby driving the upper driven bevel gear 9 and the lower driven bevel gear 10 to rotate in opposite directions simultaneously. The upper driven bevel gear 9 drives the stirring shaft 18 to rotate. The lower end of the stirring shaft 18 extends into the mixing tank 17, causing the stirring plate 19 to rotate accordingly, thus stirring the raw materials in the mixing tank 17. The lower driven bevel gear 10 drives the connecting cylinder 13 to rotate, and the connecting cylinder 13 drives the cover plate 14 to rotate. Due to the insertion and engagement of the positioning block 16 and the positioning hole 171, the cover plate 14 drives the mixing tank 17 to rotate around its own axis in the opposite direction to the stirring shaft 18. During the stirring process, the turbulence holes 20 on the stirring plate 19 change the material flow state and promote the full mixing of the materials.

[0042] Once the raw materials have been mixed to the required uniformity, the rotating motor 12 is stopped, and the solenoid valve at the lower end of the mixing tank 17 is opened. The mixed raw materials fall through the feed pipe into the collection box 22 below. The collection box 22 can be easily removed along the guide groove 21 for subsequent processing of the mixed raw materials.

[0043] When the equipment needs to be cleaned, lift the top plate 6 upwards so that multiple guide rods 5 slide upwards along the guide holes 4. The positioning block 16 is pulled out from the positioning hole 171, separating the cover plate 14 from the mixing tank 17. Then, the interior of the mixing tank 17, the stirring plate 19, and the cover plate 14 can be cleaned one by one.

[0044] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
