Description

Technical Field

[0001] This utility model relates to the field of formulation machine technology, and in particular to a weighing formulation machine for automatic proportioning of multiple materials. Background Technology

[0002] A batching machine, also known as a mixing machine, is a device used to weigh and mix materials. Most existing batching machines have only one mixing hopper. During use, each material needs to be weighed and measured manually before being added to the mixing hopper and mixed thoroughly. This type of batching machine requires manual weighing of each material, resulting in low work efficiency and a high risk of human error.

[0003] Some formula machines use vibration to make the material slide from the storage mechanism into the mixing tank, but vibration makes it difficult to control the flow rate of the material sliding down and is also prone to errors. Utility Model Content

[0004] This invention provides a weighing and formulating machine for automatic proportioning of multiple materials, which solves the technical problem that existing formulating machines are prone to errors.

[0005] To achieve this technical objective, the present invention adopts the following solution: a weighing and formulating machine for automatic proportioning of multiple materials, comprising a mixing tank, a feeding channel, a first support frame and multiple feeding mechanisms;

[0006] The mixing tank has an opening at the top for feeding.

[0007] One end of the feeding channel is located above the opening, and the other end of the feeding channel is fixed on the first support frame. The end of the feeding channel connected to the first support frame is higher than the other end.

[0008] Multiple feeding mechanisms are mounted on the first support frame, and each feeding mechanism has a feeding channel below its discharge port.

[0009] Furthermore, the bottom of the mixing tank is provided with an outlet for discharging material, and a second support frame is fixed to the outside of the mixing tank.

[0010] Furthermore, the first support frame includes a support plate and support legs;

[0011] The support plate is curved.

[0012] The support legs are fixed to the bottom of the support plate.

[0013] Furthermore, the feeding mechanism includes a fixed plate, a storage bin, a scraper body, a scraper bracket, and a motor;

[0014] The fixing plate is fixed on the support plate, and the fixing plate has a discharge port;

[0015] The storage bin is rotatably mounted above the fixed plate. The bottom of the storage bin has multiple storage holes that are evenly spaced along its circumference. A frustum is fixed in the middle of the storage bin.

[0016] The bottom of the scraper body abuts against the bottom of the storage hopper, and the top of the scraper body is fixedly connected to the scraper bracket;

[0017] The scraper bracket is fixed to the fixed plate;

[0018] The motor is fixedly mounted at the bottom of the support plate, and the output end of the motor passes through the support plate and the fixed plate and is coaxially and fixedly connected to the storage tank.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] 1. This utility model is equipped with multiple feeding mechanisms, each of which can add one type of material. The material enters the feeding channel through the feeding mechanism and finally enters the mixing tank through the opening to be mixed evenly, thus realizing the automatic feeding of multiple materials.

[0021] 2. In operation, the feeding mechanism of this utility model uses a motor to drive the storage bin to rotate. A scraper removes material from the top of the storage hole, making the material at the top of the storage hole approximately flush with the inlet. When the storage hole aligns with the outlet, material enters the outlet through the storage hole and then flows into the mixing bin through the feeding channel. The amount of material fed each time is approximately equal to the volume of the storage hole. The total amount of material entering the mixing bin is determined by the number of storage holes passing through the outlet. The amount of material used can be controlled by adjusting the rotation angle of the storage bin, ensuring accurate weighing. Attached Figure Description

[0029] To fully understand the purpose, features and effects of this utility model, the following specific embodiments will be used to describe this utility model in detail, but this utility model is not limited thereto.

[0030] like Figures 1 to 5 As shown, this utility model provides a multi-material automatic weighing and formulating machine, including a mixing tank 1, a feeding channel 2, a first support frame 3, and multiple feeding mechanisms 4. The mixing tank 1 has an opening 11 at the top for feeding, and an outlet 12 at the bottom for discharging. A second support frame 5 is fixed to the outside of the mixing tank 1. The mixing tank 1 is fixed to the ground by the second support frame 5.

[0031] One end of the feeding channel 2 is positioned above the opening 11. The feeding channel 2 can be suspended above the opening 11 by external support, which is not a limitation of this application. The other end of the feeding channel 2 is fixed to the bottom of the first support frame 3, and the end of the feeding channel 2 connected to the first support frame 3 is higher than the other end.

[0032] Preferably, the first support frame 3 includes a support plate 31 and a support leg 32; the support plate 31 is arc-shaped, the support leg 32 is fixed to the bottom of the support plate 31, and the material discharge channel 2 is also fixed to the bottom of the support plate 31.

[0033] In this embodiment, there are three feeding mechanisms 4, which are equally spaced on the first support frame 3. Each feeding mechanism 4 has a feeding channel 2 below its discharge port 41. Further, the feeding mechanism 4 includes a fixed plate 42, a storage bin 43, a scraper body 44, a scraper bracket 45, and a motor 46. The fixed plate 42 is fixed to the top surface of the support plate 31 and has only one discharge port 41 located above the feeding channel 2. The storage bin 43 is rotatably mounted on the top surface of the fixed plate 42. The bottom of the storage bin 43 has multiple storage holes 47 evenly spaced along its circumference, and a frustum 48 is fixed in the middle of the storage bin 43.

[0034] The bottom of the scraper body 44 abuts against the bottom of the storage hopper 43, and the top of the scraper body 44 is fixedly connected to the scraper bracket 45. Preferably, the scraper body 44 should fit as closely as possible to the inner wall and the frustum 48 of the storage hopper 43 so that the scraper body 44 can isolate the material in the storage hopper 43. That is, when the storage hopper 43 rotates, the material is blocked by the scraper body 44, and most of the material accumulates on one side of the scraper body 44.

[0035] The scraper bracket 45 is fixed on the fixed plate 42, so that the scraper body 44 does not rotate with the storage bucket 43.

[0036] The motor 46 is fixedly mounted at the bottom of the support plate 31. The output end of the motor 46 passes through the support plate 31 and the fixed plate 42 and is coaxially and fixedly connected to the storage tank 43.

[0037] In use, first pour the various materials into different storage bins 43, then start the motor 46. The motor 46 drives the storage bins 43 to rotate. During this process, the scraper body 44 scrapes the material at the top of the storage hole 47, so that the storage hole 47 is full of material and there is no material overflowing above it. During the rotation, the storage hole 47 is aligned with the discharge port 41. The material flows from the storage hole 47 into the discharge port 41, and then enters the mixing bin 1 through the feeding channel 2 to be mixed.

[0038] Preferably, the motor 46 is a stepper motor, which can align one of the storage holes 47 with the discharge port 41 in each operation.

[0039] Furthermore, the material in the storage bin 43 should not be too much, so as to prevent the material from accumulating too much on one side of the scraper body 44 and overflowing from the storage bin 43, causing waste.

[0040] Finally, it should be noted that the above-listed embodiments are merely preferred embodiments of the present invention. Of course, those skilled in the art can make modifications and variations to the present invention. If such modifications and variations fall within the scope of the claims of the present invention and their equivalents, they should be considered as being within the protection scope of the present invention.
