Abstract

This utility model discloses a lifting hopper mixing device, including a support frame and a hopper. A ring is fitted on the hopper, and the ring is slidably connected to the support frame. A gear is fitted on the hopper, and the gear is slidably connected to the support frame. A stirring mechanism is fixedly installed on the hopper. During the hopper's ascent, the hopper rotates on its own in the opposite direction to the stirring direction of the stirring mechanism. This relates to the field of hopper mixing technology. The stability of the hopper's lifting and lowering is ensured by the U-shaped guide rail in the support frame and the ring on the hopper. The U-shaped support column in the support frame meshes with the gear on the hopper, causing the hopper to rotate during the ascent. By controlling the rotation direction of the stirring rod in the stirring mechanism, the rotation direction of the stirring rod is made opposite to the rotation direction of the hopper, resulting in a greater relative speed difference between the stirring rod and the material, thus achieving more thorough mixing of the material.

Description

Technical Field

[0001] This utility model relates to the field of hopper mixing technology, specifically to a lifting hopper mixing device. Background Technology

[0002] A hopper mixer is a device for uniformly mixing materials such as powders and granules. Its working principle primarily involves the continuous rotation and tumbling of the hopper to mix the materials. After loading the materials to be mixed into the hopper, the equipment is started to make the hopper rotate. During rotation, the hopper continuously tumbles, ensuring the material is evenly distributed within the hopper. When the hopper reaches a certain angle, it automatically tilts, discharging the mixed material. The hopper mixer mainly consists of a mixing chamber, blades, and a motor. The motor drives the blades to rotate via belt drive, creating fluidization within the mixing chamber. This causes the material to continuously tumble, collide, disperse, and mix, achieving a uniform mixing effect. When using a hopper mixer, the specified amount of material must be added according to the process control requirements, and the motor speed must be adjusted within the specified range. After mixing is complete, the machine is stopped by adjusting the motor speed button, and the discharge port is opened for refilling. Hopper mixers are widely used in the pharmaceutical, food, and chemical industries for mixing various powders and granules. A lifting hopper mixer, on the other hand, mixes materials as the hopper rises.

[0003] Existing lifting hopper mixing equipment has the following shortcomings:

[0004] Material mixing is achieved solely by rotating the hopper. The material rotates in the same direction as the hopper, with denser components moving in front and less dense components moving behind. As a result, the material is difficult to mix effectively in a short period of time. Utility Model Content

[0005] In view of the problems existing in a current lifting hopper mixing device, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a lifting hopper mixing device that solves the problem of mixing materials by simply rotating the hopper, where the materials rotate in the same direction as the hopper, with the denser components in front and the less dense components in the back, making it difficult to achieve effective mixing of materials in a short time.

[0007] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0008] A lifting hopper mixing device includes a support frame and a hopper. A ring is fitted on the hopper and is slidably connected to the support frame. A gear is fitted on the hopper and is slidably connected to the support frame.

[0009] A stirring mechanism is fixedly installed on the hopper. During the process of the hopper rising, the hopper rotates on its own and in the opposite direction to the stirring direction of the stirring mechanism.

[0010] In a preferred embodiment of the lifting hopper mixing device described in this utility model, the support frame includes a bottom support plate, two U-shaped guide rails are welded to both ends of the bottom support plate, and a U-shaped support column is welded to the bottom support plate.

[0011] In a preferred embodiment of the lifting hopper mixing device described in this utility model, the inner wall of the U-shaped guide rail is slidably connected to a ring, the inner wall of the U-shaped support column has teeth, and the U-shaped support column is connected to a gear through meshing between the teeth.

[0012] As a preferred embodiment of the lifting hopper mixing device described in this utility model, the hopper has an inlet and outlet, the top of the inlet and outlet is covered with a sealing cover, the sealing cover and the inlet and outlet are hinged together by a hinge, and the opposite end of the sealing cover is connected to the inlet and outlet by a snap fastener.

[0013] As a preferred embodiment of the lifting hopper mixing device described in this utility model, it further includes a lifting mechanism;

[0014] The lifting mechanism includes an L-shaped support plate welded to the bottom support plate, a U-shaped support frame welded to the top of the L-shaped support plate, a first servo motor fixedly mounted on the U-shaped support frame, the output shaft of the first servo motor connected to a winding drum via a coupling, a steel wire rope wound on the winding drum, a hanging ring connected to the bottom end of the steel wire rope, the hanging ring welded to a large bearing, and the large bearing fixedly mounted on the hopper.

[0015] In a preferred embodiment of the lifting hopper mixing device of this utility model, the stirring mechanism includes a second servo motor fixedly installed on the hopper, the output shaft of the second servo motor is connected to the stirring shaft through a coupling, and a stirring rod is fixedly installed on the stirring shaft.

[0016] Compared with existing technologies:

[0017] The stability of the hopper's lifting and lowering is ensured by the U-shaped guide rail in the support and the ring on the hopper. The U-shaped support column in the support meshes with the gear on the hopper, causing the hopper to rotate during its ascent. By controlling the rotation direction of the stirring rod in the mixing mechanism, the rotation direction of the stirring rod is made opposite to that of the hopper, resulting in a greater relative speed difference between the stirring rod and the material, thus achieving more thorough mixing of the material.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0024] This utility model provides a lifting hopper mixing device. Please refer to [link / reference]. Figure 1-4 It includes a support frame and a hopper 11. A ring 10 is sleeved on the hopper 11 and is slidably connected to the support frame. A gear 16 is sleeved on the hopper 11 and is slidably connected to the support frame.

[0025] A stirring mechanism is fixedly installed on the hopper 11. During the process of the hopper 11 rising, the hopper 11 rotates on its own and in the opposite direction to the stirring direction of the stirring mechanism.

[0026] The support frame includes a bottom support plate 1, with two U-shaped guide rails 2 welded to both ends of the bottom support plate 1. The four U-shaped guide rails 2 limit the ring 10 on the hopper 11, thereby ensuring the stability of the lifting and lowering of the hopper 11. U-shaped support columns 3 are welded on the bottom support plate 1.

[0027] The inner wall of the U-shaped guide rail 2 is slidably connected to the ring 10. The inner wall of the U-shaped support column 3 has teeth that are equidistant from the entire height of the U-shaped support column 3. The U-shaped support column 3 is connected to the gear 16 through the meshing of the teeth. Thus, during the process of the hopper 11 rising, the gear 16 will rotate under the action of the U-shaped support column 3, and the gear 16 will drive the hopper 11 to rotate.

[0028] The hopper 11 has an inlet / outlet 14, and the top of the inlet / outlet 14 is covered with a sealing cover 20. The sealing cover 20 and the inlet / outlet 14 are hinged together by a hinge 15. The opposite end of the sealing cover 20 is connected to the inlet / outlet 14 by a snap fastener. That is, the sealing cover 20 and the inlet / outlet 14 are respectively equipped with a female snap fastener and a female snap fastener.

[0029] It also includes a lifting mechanism; the lifting mechanism includes an L-shaped support plate 13 welded to the bottom support plate 1, a U-shaped support frame 4 welded to the top of the L-shaped support plate 13, a first servo motor 5 fixedly installed on the U-shaped support frame 4, the output shaft of the first servo motor 5 connected to a winding drum 6 via a coupling, a bearing seat 7 fixedly installed on the U-shaped support frame 4, the other end of the winding drum 6 rotatably connected to the bearing seat 7 via a bearing, a steel wire rope 8 wound on the winding drum 6, a hanging ring connected to the bottom end of the steel wire rope 8, the hanging ring welded to a large bearing 9, and the large bearing 9 fixedly installed on the hopper 11; the first servo motor 5 drives the winding drum 6 to rotate, thereby winding and releasing the steel wire rope 8, realizing the lifting and lowering of the hopper 11.

[0030] The mixing mechanism includes a second servo motor 12 fixedly mounted on the hopper 11. The output shaft of the second servo motor 12 is connected to the mixing shaft 17 via a coupling. A mixing rod 18 is fixedly mounted on the mixing shaft 17. Specifically, the mixing rod 18 has a collar 181 in the middle, which is sleeved on the mixing shaft 17 and fixed to the mixing shaft 17 by bolts. The second servo motor 12 drives the mixing shaft 17 and the mixing rod 18 to rotate in the opposite direction to the rotation of the hopper 11, thereby making the relative speed difference between the mixing rod 18 and the material flow greater, and achieving more thorough mixing of the material.

[0031] In practical use, the first servo motor 5 drives the winding drum 6 to wind up the wire rope 8, thereby lifting the hopper 11. Under the action of the U-shaped support column 3, the gear 16 will rotate, and the gear 16 will drive the hopper 11 to rotate. At the same time, the second servo motor 12 is started, and the second servo motor 12 drives the stirring shaft 17 and the stirring rod 18 to rotate. The stirring rod 18 stirs the material, and the rotation direction of the stirring rod 18 is opposite to the rotation direction of the hopper 11, thereby achieving thorough mixing of the material.
