Description

Technical Field

[0001] This utility model relates to the field of boron nitride and kaolin mixing technology, specifically a stirring device for mixing boron nitride and kaolin. Background Technology

[0002] Boron nitride and kaolin can be mixed for use in electronic heat dissipation substrates, insulating shells, thermal interface materials, and other fields. Kaolin, as a low-cost mineral filler, can reduce material costs. Boron nitride's high thermal conductivity and lubricity can be used to reinforce the functional shortcomings of the kaolin matrix and improve the overall performance of the composite material. In order to achieve efficient mixing and precise batching of kaolin and boron nitride, this utility model proposes a stirring device for mixing boron nitride and kaolin. Summary of the Invention

[0003] The purpose of this invention is to provide a mixing device for mixing boron nitride and kaolin, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a mixing device for mixing boron nitride and kaolin, comprising a mixing drum and a storage cylinder disposed above the side of the mixing drum. A weighing hopper is disposed at the bottom of the storage cylinder and is mounted on a weighing platform of a weighing mechanism. A feeding hopper is disposed on the top side of the mixing drum, with the weighing hopper positioned above one end and connected to the interior of the mixing drum at the other end. Two support plates are fixedly connected to the top of the weighing platform. Connecting shafts are connected to both ends of the weighing hopper; one connecting shaft passes through a slot on the side of the feeding hopper and is rotatably connected to a support plate, while the other connecting shaft passes through a slot on the side of the feeding hopper and is connected to the output end of a motor, which is fixedly mounted on the support plate. This design avoids contact between the weighing hopper, connecting shafts, support plates, and the feeding hopper, which could affect the weighing results of the weighing mechanism. The weighing mechanism can be an electronic scale. When the resistance strain gauge on the electronic scale deforms under the action of external force, its resistance changes. This change in resistance is converted into an electrical signal by the corresponding measuring circuit and transmitted to the control system. After the material to be weighed is weighed, the control motor drives the weighing hopper to rotate, so that the material falls into the feeding hopper during the rotation and enters the mixing drum from the feeding hopper for mixing.

[0005] Preferably, a stirring rod is rotatably installed inside the stirring drum, the top of the stirring rod extends out of the stirring drum and connects to the output end of a motor located at the top of the stirring drum, and multiple stirring blades are provided on the stirring rod.

[0006] Preferably, the bottom of the mixing drum and the bottom of the storage drum are provided with discharge pipes, and an electronic valve for controlling the passage of materials is provided on the discharge pipes. By setting the electronic valve, it is convenient to control the material in the storage drum to enter the weighing hopper for weighing, and to stop feeding material into the weighing hopper after the weight of the material in the weighing hopper reaches the set value. The electronic valve on the discharge pipe at the bottom of the mixing drum opens after the mixing is completed, and the mixed material is discharged.

[0007] Preferably, a baffle is slidably disposed inside the mixing drum, the baffle being penetrated and slidably connected to the mixing rod. An electric push rod is disposed at the top of the mixing drum, and the telescopic end of the electric push rod is connected to the top of the baffle. The baffle can move up and down inside the mixing drum via the connected electric push rod. During mixing operations, the baffle is moved down so that it is located below the connection between the feed hopper and the inside of the mixing drum. During mixing, the powdery material that is dispersed inside the mixing drum due to mixing is blocked by the baffle and will not float out of the feed hopper.

[0008] Compared with the prior art, the beneficial effects of this utility model are: by placing different materials in different storage cylinders, setting up a weighing mechanism and a weighing hopper to weigh the required materials, the materials are then fed from the feed hopper into the mixing cylinder for stirring and mixing. The baffle can prevent the dust generated by stirring from scattering. Attached Figure Description

[0013] 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.

[0014] Referring to Figures (1-3), a mixing device for mixing boron nitride and kaolin includes a mixing drum 1 and a storage drum 2 disposed above the side of the mixing drum 1. A weighing hopper 3 is disposed at the bottom of the storage drum 2 and is disposed on a weighing platform 41 on a weighing mechanism 4. A feeding hopper 14 is disposed on the top side of the mixing drum 1. The weighing hopper 3 is disposed above one end of the feeding hopper 14 and the other end of the feeding hopper 14 is connected to the inside of the mixing drum 1. Two support plates 32 are fixedly connected to the top of the weighing platform 41. Connecting shafts 31 are connected to both ends of the weighing hopper 3. One connecting shaft passes through a slot opened on the side of the feeding hopper 14 and is rotatably connected to the support plate 32. The other connecting shaft passes through a slot opened on the side of the feeding hopper 14 and is connected to the output end of a motor. The motor is fixedly mounted on the support plate 32.

[0015] A stirring rod 11 is rotatably mounted inside the stirring drum 1. The top of the stirring rod 11 extends out of the stirring drum 1 and connects to the output end of a motor located at the top of the stirring drum 1. Discharge pipes are located at the bottom of the stirring drum 1 and the bottom of the storage drum 2, and electronic valves for controlling the passage of materials are installed on the discharge pipes. A partition 12 is slidably mounted inside the stirring drum 1, and the partition 12 is penetrated and slidably connected to the stirring rod 11. An electric push rod 13 is located at the top of the stirring drum 1, and the telescopic end of the electric push rod 13 is connected to the top of the partition 12.

[0016] When using this device, the material is stored in the storage cylinder 2. By controlling the electronic valve on the discharge pipe at the bottom of the storage cylinder 2 to open, the material in the storage cylinder 2 falls into the weighing hopper 3. The weight increase measured by the weighing mechanism 4 is the weight of the material in the weighing hopper 3. After weighing to the required weight, the motor drives the weighing hopper 3 to rotate, causing the material in the weighing hopper 3 to fall onto the feeding hopper 14 and slide along the feeding hopper 14 into the mixing drum 1. After the material is added, the electric push rod 13 is controlled to push the partition 12 downward, so that the partition 12 is located below the connection between the feeding hopper 14 and the mixing drum 1. Then, the motor is started to drive the mixing shaft to rotate and mix the material.
