Description

Technical Field

[0001] This utility model relates to the field of vacuum mixer technology, specifically a vacuum mixer that is easy to feed. Background Technology

[0002] A vacuum mixer is a device that mixes materials in a vacuum environment. It creates a vacuum in a sealed container, eliminating air and other gases, thereby preventing the materials from oxidizing, decomposing, or being contaminated by other gases during the mixing process. This type of equipment is often used for mixing oxygen-sensitive materials, such as food, pharmaceuticals, and chemical raw materials.

[0003] Existing vacuum mixers mainly rely on vacuum feeders for material supply. This reliance limits production flexibility, increases system complexity and cost. Moreover, current vacuum feeders often require manual operation at the suction end to ensure material intake, which is very troublesome. Therefore, a vacuum mixer that is easy to feed is proposed.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0007] Preferably, a speed reducer is connected to the bottom of the mixer body, and a drive motor is connected to one side of the speed reducer.

[0008] Preferably, a corrugated pipe is connected to the top of the transfer hopper, and the other end of the corrugated pipe is connected to the extraction pipe.

[0009] Preferably, the bottom end of the fixed platform is provided with a guide hole, and the bottom end of the extended platform is connected with a bolt, the bottom end of the bolt passing through the guide hole and connected with a compression nut.

[0019] 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.

[0020] Please see Figure 1-3 This utility model provides a technical solution: it includes a mixer body 1, a connecting frame 4 rotatably mounted on the outer surface of the mixer body 1, wherein an anti-slip rubber sleeve is connected to the inner side of the connecting frame 4, thereby increasing the damping effect between the connecting frame 4 and the mixer body 1, so that it will not shake after rotation and adjustment. A fixed platform 5 is connected to one side of the connecting frame 4, and an extension platform 6 is slidably mounted on one side of the fixed platform 5. A transfer hopper 7 is connected to the top of the extension platform 6, and an air extraction tank 8 is connected to the top of the transfer hopper 7. A vacuum pump 9 is connected to the other end of the air extraction tank 8. A feeding pipe 10 is connected to one side of the bottom of the transfer hopper 7, and the other end of the feeding pipe 10 is connected to the mixer body 1. The main body 1 of the feeder is connected to the extension platform 6. A suction pipe 11 is slidably installed on one side of the extension platform 6. A valve is connected to one end of both the feeding pipe 10 and the suction pipe 11. Since this is a conventional setting, it is not described in detail in the manual. The bottom end of the suction pipe 11 passes through the extension platform 6 and is connected to a suction hopper 12. A protective fence 13 is connected to the outer ring of the suction hopper 12. A ball bearing 14 is rotatably installed on the outer ring of the protective fence 13. An air inlet pipe 15 is connected to the top surface of the suction hopper 12. A drive unit is connected to the top of the extension platform 6. A loading bucket 121 for loading materials is set below the suction hopper 12. Materials to be fed into the main body 1 of the feeder can be poured into the loading bucket 121.

[0021] Reference Figure 2 As shown, the mixer body 1 is a conventional vacuum mixing device, connected to a corresponding vacuum pump. It has an internal stirring shaft and stirring blades. Since it is a mature technology, it is not described in detail in the manual. A reducer 2 is connected to the bottom of the mixer body 1, and a drive motor 3 is connected to one side of the reducer 2 to drive the internal stirring shaft.

[0022] Reference Figure 1 As shown, a corrugated pipe 16 is connected to the top of the transfer hopper 7. The other end of the corrugated pipe 16 is connected to the extraction pipe 11. When the extraction pipe 11 is driven up and down by the drive unit, the corrugated pipe 16 can maintain the connection between the extraction pipe 11 and the transfer hopper 7 by its own extensibility, so as to ensure the feeding effect.

[0023] Reference Figure 2As shown, a guide hole is provided at the bottom of the fixed platform 5, and a bolt 20 is connected to the bottom of the extension platform 6. The bottom end of the bolt 20 passes through the guide hole and is connected to a compression nut 21. A pull buckle is connected to one side of the extension platform 6. The extension platform 6 can be pulled out from the fixed platform 5 by pulling the buckle, thereby adjusting the feeding position. Then, the compression nut 21 is rotated to compress the fixed platform 5, thereby completing the positioning between the extension platform 6 and the fixed platform 5 and ensuring the stability of use.

[0024] Reference Figure 3 As shown, the drive unit includes a fixed mounting frame 17, with two drive rollers 18 connected between the mounting frames 17. A servo motor 19 is connected to one side of the mounting frame 17, and the output end of the servo motor 19 is connected to one of the drive rollers 18. The suction pipe 11 is located between the two drive rollers 18, and its two sides abut against the drive rollers 18. Starting the servo motor 19 can drive the drive rollers 18 to rotate. The drive rollers 18, through the squeezing between themselves and the suction pipe 11, drive the suction pipe 11 to move up and down, thereby completing the position adjustment of the suction hopper 12. As the material is sucked in, the suction hopper 12 can be continuously driven downward to keep it on the surface of the material, ensuring the feeding effect.

[0025] The implementation principle of this application is as follows: When using this utility model, the material container 121 is placed in the correct position according to the surrounding environment of the mixing machine body 1. Then, the position of the suction hopper 12 is adjusted by rotating the connecting frame 4 so that it is directly above the material container 121. Then, the vacuum pump 9 is started to put the transfer hopper 7 into a negative pressure state. Then, the drive unit is started to drive the suction pipe 11 to move down until the suction hopper 12 enters the material container 121. When the suction hopper 12 enters the material container 121, the ball bearings 14 on the outer ring of the protective fence 13 are exactly aligned with the material container. The inner walls of 121 are pressed together, and then the valve at one end of the extraction pipe 11 is opened. The negative pressure is used to draw the raw material in the loading bucket 121. The air inlet pipe 15 can ensure the entry of air, so that the material can enter the extraction pipe 11 well. After the material enters the extraction pipe 11, it falls to the bottom of the transfer hopper 7 by its own weight. The air is discharged by the vacuum pump 9. After there is enough material in the transfer hopper 7, the valve at one end of the feeding pipe 10 is opened. The negative pressure in the mixer body 1 draws the material in the transfer hopper 7 through the feeding pipe 10, thus completing the feeding.
