Description

Technical Field

[0001] This utility model relates to the field of mixing devices, and more particularly to a mixing device used in the plaster production industry. Background Technology

[0002] Plaster production requires mixing various raw materials, including plaster, aggregates, and fibers. Mixing these materials evenly requires a lot of manpower and time, and the mixing process can also affect the health of workers. Therefore, mixing devices for plaster production have emerged in the industry to replace manual mixing.

[0003] Most existing plastering powder mixing devices in the building materials industry rely on manual pouring of raw materials into a tank, where a motor drives a stirring rod for mixing. This process results in uneven mixing of plaster powder, failing to reach every part of the mixing device and leading to low mixing efficiency. Furthermore, manual handling, unloading, and pouring of raw materials further reduce work efficiency. Additionally, the discharge port cannot be precisely controlled. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an automatic bag-breaking and filling airflow dust-dispersing mixing device, which aims to improve the problems of uneven mixing, low stirring efficiency, and time-consuming and labor-intensive process of disassembling and refilling raw material bags.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a mixing device for plaster production, comprising an airflow mixing tank and a circular base. The airflow mixing tank is equipped with a mixing assembly. A coaxial rotary motor is fixedly connected to the center of the circular base. A motor support hydraulic rod and a clamping mechanism support hydraulic rod are slidably connected in the groove of the circular base. A lead screw motor is fixedly connected to the top of the motor support hydraulic rod. A sliding clamp rod is threadedly connected to the outer wall of the lead screw motor. Fixed rods are fixedly connected to both sides of the lead screw motor. A double-output tooth motor is fixedly connected to the other side of the two fixed rods. A toothed sliding groove rod is rotatably connected to both output ends of the double-output tooth motor. A toothed sliding groove rod is slidably connected to both toothed sliding groove rods.

[0006] The stirring assembly includes a stirring motor, a coaxial reverse gear mechanism, and two coaxial reverse stirring blades. The outer wall of the stirring motor is fixedly connected to the outer wall. The output end of the stirring motor is fixedly connected to the drive shaft of the coaxial reverse gear mechanism. The outer wall of the coaxial reverse gear mechanism is provided with a bearing dust cover. The two output shafts inside the coaxial reverse gear mechanism are respectively fixedly connected to the two coaxial reverse stirring blades.

[0007] As a further description of the above technical solution:

[0008] A gear hydraulic rod is fixedly connected to the lower part of the lead screw motor, and a coaxial gear is fixedly connected to the outer wall of the gear hydraulic rod.

[0009] As a further description of the above technical solution:

[0010] The output end of the coaxial rotary motor is rotatably connected to the gear hydraulic rod.

[0011] As a further description of the above technical solution:

[0012] The top and bottom of the airflow mixing tank are fixedly connected to an upper spherical three-way valve and a lower spherical three-way valve. The top of the upper spherical three-way valve is fixedly connected to a feeding trough. The top of the feeding trough is slidably connected to a sliding cover. The edge of the sliding cover is rotatably connected to a linkage rod. The other end of the linkage rod is slidably connected to a rack.

[0013] As a further description of the above technical solution:

[0014] The coaxial gear is meshed with a rack.

[0015] As a further description of the above technical solution:

[0016] The lower spherical three-way valve is fixedly connected to an electromagnetic discharge valve and a pipeline particle air pump.

[0017] As a further description of the above technical solution:

[0018] The electromagnetic discharge valve is fixedly connected to the discharge funnel nozzle.

[0019] As a further description of the above technical solution:

[0020] The coaxial counter-stirring fan blades are rotatably connected to a wave-shaped screen.

[0021] This utility model has the following beneficial effects:

[0022] In this invention, the clamping mechanism first uses three hydraulic rods to position the sliding clamping rod at the top of the bagged raw material. Then, the sliding clamping rod is pushed by a screw motor to clamp the raw material bag. At this time, the hydraulic rods rise to a higher height, lifting the raw material bag. When the raw material bag is higher than the feeding trough, the coaxial rotary motor rotates towards the feeding trough. At this time, the coaxial gear also rotates accordingly, driving the rack and linkage rod to open the sliding cover. The dual-output motor of the top blade tooth of the clamping device starts to rotate, rotating the blade tooth rod down from the top. When the blade tooth rod pierces into the raw material bag, the blade tooth rod slides through the blade tooth sliding groove rod, cutting an opening in the raw material bag, allowing the raw material particles to fall into the feeding trough.

[0023] In this invention, the airflow mixing tank draws in raw materials through a pipeline particle pump. After passing through the corrugated screen of the airflow mixing tank, the granular raw materials fall into the coaxial counter-rotating mixing blades for mixing. At the same time, the raw materials at the bottom are transported to the top of the airflow mixing tank through the lower spherical three-way valve and the pipeline particle pump, achieving dust-free mixing and making the mixing more efficient, faster and more uniform.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-5This utility model provides an embodiment of a mixing device for plaster production, comprising an airflow mixing tank 1 and a circular base 17. The airflow mixing tank 1 is internally equipped with a mixing assembly. A coaxial rotary motor 23 is fixedly connected to the center of the circular base 17, providing a main support rotation point for the clamping mechanism. A motor-supporting hydraulic rod 18 and a clamping mechanism-supporting hydraulic rod 19 are slidably connected within a groove in the circular base 17, allowing them to slide according to the power provided by the coaxial rotary motor 23 at the main support point. A lead screw motor 7 is fixedly connected to the top of the motor-supporting hydraulic rod 18, and the lead screw motor 7 has a screw thread on its outer wall. The screw motor 7 is connected to a sliding clamp rod 8, which allows the sliding clamp rod 8 to move. The screw motor 7 is fixedly connected to two fixed rods 21 on both sides. The two ends of the fixed rods 21 are fixedly connected to the outer shell bracket of the screw motor 7 and the dual-output end motor 9 of the cutting teeth. The other side of the two fixed rods 21 is fixedly connected to the dual-output end motor 9 of the cutting teeth. The two output ends of the dual-output end motor 9 of the cutting teeth are rotatably connected to the cutting tooth sliding groove rods 10, which allows the cutting tooth sliding groove rods 10 to rotate and move the cutting tooth rod 11. The two cutting tooth sliding groove rods 10 are slidably connected to the cutting tooth rod 11, which allows the cutting tooth rod 11 to move and cut open the packaging bag.

[0033] The mixing assembly includes a mixing motor 6, a coaxial counter-rotating gear mechanism 27, and two coaxial counter-rotating mixing blades 24. The outer wall of the mixing motor 6 is fixedly connected to the outer wall of the airflow mixing tank 1. The output end of the mixing motor 6 is fixedly connected to the drive shaft of the coaxial counter-rotating gear mechanism 27. The outer wall of the coaxial counter-rotating gear mechanism 27 is provided with a bearing dust cover 25. The two output shafts inside the coaxial counter-rotating gear mechanism 27 are respectively fixedly connected to the two coaxial counter-rotating mixing blades 24. This allows for mixing in different directions within the airflow mixing tank 1, resulting in more uniform mixing of the raw materials.

[0034] Reference Figures 1-3 The lower part of the lead screw motor 7 is fixedly connected to the gear hydraulic rod 22, and the outer wall of the gear hydraulic rod 22 is fixedly connected to the coaxial gear 12. The output end of the coaxial rotary motor 23 is rotatably connected to the gear hydraulic rod 22.

[0035] Specifically, this allows the lead screw motor 7 to have a support point and to rotate together with the gear hydraulic rod 22 and the coaxial gear 12 to transfer raw materials.

[0036] Reference Figure 1 The top and bottom of the airflow mixing tank 1 are fixedly connected to an upper ball three-way valve 3 and a lower ball three-way valve 5. The top of the upper ball three-way valve 3 is fixedly connected to a feeding trough 16. The top of the feeding trough 16 is slidably connected to a sliding cover 15. The edge of the sliding cover 15 is rotatably connected to a linkage rod 14. The other end of the linkage rod 14 is slidably connected to a rack 13. The coaxial gear 12 is meshed with the rack 13. The lower ball three-way valve 5 is fixedly connected to an electromagnetic discharge valve 4 and a pipeline particle air pump 2. The electromagnetic discharge valve 4 is fixedly connected to a discharge funnel nozzle 20.

[0037] Specifically, when the airflow mixing tank 1 is filled with raw materials, the upper ball three-way valve 3 opens the channel to the feeding trough 16, while other channels are closed; during the mixing process, the upper ball three-way valve 3 opens the connection to the lower ball three-way valve 5, so that the raw materials circulate and mix in the airflow mixing tank 1; when the mixing is completed and the material is discharged, the lower ball three-way valve 5 opens the channel on one side of the electromagnetic discharge valve 4 to discharge the material, while other outlets are closed.

[0038] Reference Figure 1 A wave screen 26 is rotatably connected to the end of the coaxial counter-stirring fan blade 24.

[0039] Specifically, the raw materials are refined by passing through the wave screen 26 and then stirred more evenly by the coaxial reverse stirring fan blades 24.

[0040] Working principle: First, the bagged raw material is placed into the operating range of the clamping device. The motor-supported hydraulic rod 18, the clamping mechanism-supported hydraulic rod 19, and the gear hydraulic rod 22 in the clamping device simultaneously lower their heights, aligning the height of the sliding clamp rod 8 with the top height of the raw material belt. Then, the screw motor 7 pushes the sliding clamp rod 8 forward, squeezing the raw material bag onto the other clamp rod for clamping. Subsequently, the three supporting hydraulic rods raise their heights, lifting the bottom of the raw material bag above the feeding trough 16. The coaxial rotary motor 23 begins to rotate towards the feeding trough 16. At this time, the clamping mechanism-supported hydraulic rod 19 and the motor-supported hydraulic rod 18 rotate concentrically around the annular base 17. The coaxial gear 12 pulls the rack 13, causing the linkage rod 14 to move backward. The sliding cover 15 is pulled back through the rotation point on the linkage rod 14, thus opening the sliding cover 15. When the material is above the feeding trough 16, the toothed rod 11 at the top of the clamping device is rotated down by the toothed double-output motor 9 and smashed into the raw material bag. The toothed rod 11 slides on the toothed sliding groove rod 10, opening the raw material bag. The raw material particles fall into the feeding trough 16 from the upper ball three-way valve 3 through the wave screen 26. The pipeline particle air pump 2 draws the raw material particles into the airflow mixing tank 1 through the pipeline. The mixing motor 6 starts to drive the coaxial reverse gear mechanism 27 to move, causing the upper and lower coaxial reverse mixing fan blades 24 in the airflow mixing tank 1 to rotate and mix. The raw material falls into the bottom of the airflow mixing tank 1 and is drawn into the pipeline through the lower ball three-way valve 5 and sent back to the top of the airflow mixing tank 1. The raw material is mixed by airflow circulation. Finally, the mixing stops, and the lower ball three-way valve 5 is rotated to accurately discharge the material through the electromagnetic discharge valve 4.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
