Description

Technical Field

[0001] This utility model relates to the field of mixing technology, and in particular to a mixing device with weighing function. Background Technology

[0002] Vitamin and mineral blends are premixed products made by mixing vitamins and minerals in a specific ratio, used to supplement nutrition, enhance health, or improve specific functions. In the production process of vitamin and mineral blends, controlling the proportions of each ingredient is the core step in ensuring product quality and efficacy. As key components of the blend, deviations in the ratio of vitamins and minerals can not only reduce the nutritional supplementation effect but may also have adverse effects due to excess or deficiency of certain components.

[0003] In existing technologies, traditional mixing processes often require manual weighing of various vitamins and minerals before transferring them to mixing equipment. This method has several drawbacks: firstly, manual weighing is susceptible to human error; secondly, multiple transfers of raw materials not only increase production steps and time costs but may also cause material loss or contamination during the transfer process. Therefore, we propose a mixing device with weighing functionality to address these issues. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a mixing device with weighing function.

The bottoms of the multiple hoppers are all fixedly interconnected with feed pipes. Rotary metering valves are fixedly installed on the outer walls of the multiple feed pipes. The bottoms of the multiple feed pipes are fixedly interconnected with the top of the tank. Two U-shaped frames are fixedly connected to the outer wall of the tank. A first motor and a second motor are fixedly connected to the inner walls of the two U-shaped frames, respectively. The top of the output shaft of the second motor passes through the bottom of the tank and is fixedly connected to a stirring shaft. A stirring blade is fixedly connected to the outer wall of the stirring shaft. A drive shaft is fixedly connected to one end of the output shaft of the first motor. A feeding assembly is provided on the outer wall of the drive shaft.

[0006] Preferably, the feeding assembly includes a material frame, a rectangular plate is fixedly sleeved on the outer wall of the drive shaft, a weighing sensor is fixedly connected to the top of the rectangular plate, the top of the detection end of the weighing sensor is fixedly connected to the bottom of the material frame, a U-shaped membrane is fixedly connected to the outer wall of the material frame, a conical guide hopper is fixedly sleeved on the outer wall of the U-shaped membrane, and the bottom of the conical guide hopper is fixedly connected to the top of the rectangular plate. By setting the feeding assembly, multiple raw materials are fed sequentially.

[0007] Preferably, the outer wall of the tank has two through holes, the inner walls of the two through holes are rotatably connected to the outer walls of the output shafts of the first motor and the second motor, respectively, and the inner walls of the two through holes are sealed.

[0008] Preferably, the outer wall of the conical guide hopper is fixedly fitted with a rubber sleeve, and the outer wall of the rubber sleeve is slidably connected to the inner wall of the tank. The rubber sleeve increases the sealing between the conical guide hopper and the tank.

[0009] Preferably, the outer wall of the tank is fixedly connected to a discharge pipe, and the outer wall of the discharge pipe is fixedly connected to an electronic valve, through which the mixed raw materials are discharged.

[0010] Preferably, a bracket is fixedly connected to the bottom of the tank to support the tank.

[0011] Compared with the prior art, the advantages of this utility model are: This solution uses a rotor metering valve at the bottom of the silo to sequentially open and close the material feeding mechanism, combined with a weighing sensor at the bottom of the material frame for real-time weighing. The two work together to avoid operational errors associated with traditional manual weighing, while eliminating the tedious process of manual weighing and multiple material transfers. The material enters the material frame from the silo via a conical guide hopper and a U-shaped membrane slope, and then falls into the tank through the tilting of the material frame. The entire process is completed in a relatively enclosed structure, reducing contact with the external environment and lowering the probability of moisture absorption for hygroscopic materials and adhesion loss for materials with poor flowability. It also avoids the contamination problems that may occur during manual transfer. Attached Figure Description

[0015] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0016] Depend on Figures 1-3 As shown, a mixing device with weighing function is disclosed, including a tank 1. A U-shaped frame 2 is fixedly connected to the top of the tank 1. Multiple hoppers 3 are fixedly connected inside the U-shaped frame 2. The U-shaped frame 2 arranges the multiple hoppers 3 in an orderly manner. The multiple hoppers 3 are used to store various raw materials such as vitamins and minerals, realizing the separate storage of different raw materials. The bottom of each of the multiple hoppers 3 is fixedly interconnected with a feed pipe 4. A rotor metering valve 5 is fixedly installed on the outer wall of each of the multiple feed pipes 4. The rotor metering valve 5 controls the amount of raw materials fed by opening and closing in sequence. The bottom of each of the multiple feed pipes 4 is fixedly interconnected with the top of the tank 1.

[0017] Two U-shaped frames are fixedly connected to the outer wall of the tank body 1. The inner walls of the two U-shaped frames are respectively fixedly connected to the first motor 6 and the second motor 7. An existing encoder is installed on the outer wall of the output shaft of the first motor 6. The encoder detects the rotation angle of the output shaft of the first motor 6. Two through holes are opened on the outer wall of the tank body 1. The inner walls of the two through holes are rotatably connected to the outer walls of the output shafts of the first motor 6 and the second motor 7, respectively. The top of the output shaft of the second motor 7 passes through the bottom of the tank body 1 and is fixedly connected to the stirring shaft 8. The outer wall of the stirring shaft 8 is fixedly connected to the stirring blade 9. The second motor 7 drives the stirring shaft 8 and the stirring blade 9 to rotate, thereby achieving the mixing of multiple raw materials.

[0018] One end of the output shaft of the first motor 6 is fixedly connected to a drive shaft 10, a discharge pipe 16 is fixedly connected to the outer wall of the tank body 1, an electronic valve is fixedly connected to the outer wall of the discharge pipe 16, and a bracket 17 is fixedly connected to the bottom of the tank body 1.

[0019] The outer wall of the drive shaft 10 is provided with a feeding assembly, which includes a material frame 13. A rectangular plate 11 is fixedly sleeved on the outer wall of the drive shaft 10. A weighing sensor 12 is fixedly connected to the top of the rectangular plate 11. The weighing sensor 12 can detect the weight of the raw material in the material frame 13 in real time. It works with the rotor metering valve 5 to achieve accurate weighing of the raw material. When the weight of the raw material reaches the preset value, the rotor metering valve 5 can be closed by the existing PLC controller to avoid excessive or insufficient raw material.

[0020] The top of the detection end of the weighing sensor 12 is fixedly connected to the bottom of the material frame 13. A U-shaped membrane 14 is fixedly connected to the outer wall of the material frame 13. A conical guide hopper 15 is fixedly sleeved on the outer wall of the U-shaped membrane 14. The U-shaped membrane 14 is fixedly connected to the outer wall of the material frame 13. It has good elasticity and sealing performance and can fill the gap between the material frame 13 and the conical guide hopper 15, so as to avoid the conical guide hopper 15 from affecting the weighing of the material frame 13.

[0021] The bottom of the conical guide hopper 15 is fixedly connected to the top of the rectangular plate 11. A rubber sleeve is fixedly fitted on the outer wall of the conical guide hopper 15. The outer wall of the rubber sleeve is slidably connected to the inner wall of the tank 1. The inclined design of the conical guide hopper 15 can guide the raw material to slide smoothly into the material frame 13, avoiding the raw material from accumulating in a certain place during the falling process.

[0022] Working principle: During use, vitamins and minerals are placed into multiple hoppers 3. The raw materials in the hoppers 3 are fed out sequentially through the opening and closing of the rotor metering valves 5 at the bottom. The vitamins and minerals are discharged downwards into the conical guide hopper 15, and then fall along the inclined surface of the conical guide hopper 15 and the U-shaped film 14 into the material frame 13. The raw materials are weighed by the weighing sensor 12 at the bottom of the material frame 13. After weighing, the rotor metering valves 5 close, and the first motor 6 rotates, driving the drive shaft 10 to rotate. The rotating shaft 10 drives the rectangular plate 11 to rotate, which in turn drives the conical guide hopper 15 to rotate. The conical guide hopper 15 and the material frame 13 rotate downwards, and the raw materials in the material frame 13 fall into the bottom of the tank 1. The first motor 6 restarts and drives the material frame 13 and the conical guide hopper 15 to reset. The above steps are repeated to weigh the raw materials in multiple hoppers 3 in sequence and then feed them. After the batching is completed, the second motor 7 rotates and drives the stirring shaft 8 to rotate. The stirring shaft 8 rotates and drives the stirring blades 9 to mix the various raw materials.

[0023] It should be noted that, in actual use, an existing PLC controller can be added. The PLC controller is electrically connected to the rotor metering valve 5, the first motor 6, the second motor 7, the weighing sensor 12, and the electronic valve, which facilitates the control of the overall operation.
