Currently, many powder and granular materials are conveyed by wind power, which can easily lead to insufficient or excessive materials in the batching bin. During the batching process, the proportion of materials can easily become unbalanced, affecting subsequent processing. Therefore, a multi-station automatic batching device is needed. Utility Model Content
[0003] The technical problem solved by this utility model is to provide a multi-station automatic batching device to solve the problems mentioned in the background art.
[0004] The technical problem solved by this utility model is achieved by the following technical solution: a multi-station automatic batching device, including a frame and negative pressure suction hoppers, buffer hoppers and metering hoppers installed on the frame. The negative pressure suction hoppers, buffer hoppers and metering hoppers are vertically installed on the frame in sequence. The negative pressure suction hoppers are arranged in a ring at the upper end of the frame, and the buffer hoppers are arranged in the middle of the frame to receive the material falling from the corresponding negative pressure suction hopper. A buffer hopper discharge valve is installed at the lower end of the buffer hopper. The metering hoppers are arranged on corresponding weighing sensors at the lower end of the frame to receive the material falling from the buffer hopper and weigh it. A metering hopper discharge valve is installed at the lower end of the metering hopper. The metering hopper discharge valve is inclined towards the center of the frame to collect the falling material for batching and mixing.
[0005] As a further embodiment of this utility model:
[0006] The upper end of the negative pressure suction hopper is provided with a negative pressure pipe to connect to the pneumatic conveying pipeline. The lower end of the negative pressure suction hopper is provided with a conical guide cylinder. The lower end of the guide cylinder is fitted with an air guide cylinder. An air guide hole is opened on one side of the air guide cylinder. The air guide hole is connected to a negative pressure device through an air pipe. The material falls from the guide cylinder into the buffer hopper.
[0007] As a further embodiment of this utility model:
[0008] The upper end of the buffer hopper is open to receive material from the negative pressure suction hopper. Buffer plates are provided on both sides of the buffer hopper, and sliders are provided on both sides of the buffer plates. The sliders are slidably mounted on the corresponding slide rails of the frame. The frame is also equipped with a displacement cylinder to drive the buffer hopper to move. The output rod of the displacement cylinder is fixedly connected to the buffer hopper through a support plate to control the reciprocating movement of the buffer hopper to adjust the receiving or discharging position.
[0009] As a further embodiment of this utility model:
[0010] The buffer hopper discharge valve includes a first valve seat, a fast discharge valve plate slidably mounted on one side of the first valve seat, and a slow discharge valve plate disposed on the other side of the first valve seat. A fast discharge cylinder is provided on one side of the valve seat to control the movement of the fast discharge valve plate, and a slow discharge cylinder is provided on the other side to control the movement of the slow discharge valve plate. Specifically, when the buffer hopper discharge valve discharges material, the fast discharge valve plate is first opened for rapid material discharge. Once a certain weight is reached, the fast discharge valve plate is closed, and the slow discharge valve plate is opened for slow material discharge, thus avoiding excessively fast discharge speed leading to overloading and improving weighing accuracy.
[0011] As a further embodiment of this utility model:
[0012] Sensor brackets are provided around the metering hopper, and weighing sensors are mounted on the sensor brackets to detect the weight of the material falling from the buffer hopper.

[0014] The metering hopper discharge valve includes an inclined second valve seat and a second valve plate slidably mounted on the upper end of the second valve seat. A valve control cylinder that drives the second valve plate to move is fixedly installed on the outer side of the upper end of the second valve seat so as to open the valve port through the valve control cylinder and discharge the material.
[0015] As a further embodiment of this utility model:
[0016] The negative pressure suction hoppers are arranged in a ring of eight, and there are four sets of buffer hoppers corresponding to the negative pressure suction hoppers, and four sets of metering hoppers corresponding to the buffer hoppers, for sequentially guiding materials.
[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: The negative pressure suction hopper, buffer hopper, and metering hopper in this device are vertically installed on the frame in sequence, allowing for sequential material feeding. The buffer hopper is used to accumulate materials and is equipped with upper and lower level sensors respectively. When the upper level is reached, the negative pressure suction hopper stops feeding; when the lower level is reached, the negative pressure suction hopper starts feeding to maintain material stability in the buffer hopper. After the metering hopper is set with a specified weight, the buffer hopper discharge valve introduces the material into the metering hopper. The weighing sensor detects the weight of the material in the metering hopper. First, the fast discharge valve plate is opened; after a certain weight is reached, the slow discharge valve plate is switched on to avoid excessive discharge speed leading to overloading and improve weighing accuracy. After the metering hopper reaches the specified weight, the buffer hopper discharge valve closes. The lower end of the metering hopper guides the material to the central area of the frame through the inclined metering hopper discharge valve, where it is collected and dispensed by the distributed metering hoppers. This device uses a combination of a buffer hopper and a metering hopper to control the weight of the material in the metering hopper, ensuring accurate batching. The lower end of the metering hopper is inclined towards the center of the frame to facilitate material collection. Attached Figure Description

[0024] like Figures 1-4 As shown,
[0025] This embodiment provides a multi-station automatic batching device, including a frame 1 and a negative pressure suction hopper 2, a buffer hopper 3, and a metering hopper 4 installed on the frame 1. The negative pressure suction hopper 2, the buffer hopper 3, and the metering hopper 4 are vertically installed on the frame 1 in sequence. The negative pressure suction hopper 2 is arranged in a ring at the upper end of the frame 1, and the buffer hopper 3 is arranged in the middle of the frame 1 to receive the material falling from the corresponding negative pressure suction hopper 2. A buffer hopper discharge valve 5 is installed at the lower end of the buffer hopper 3. The metering hopper 4 is arranged on the corresponding weighing sensor 42 at the lower end of the frame 1 to receive the material falling from the buffer hopper 3 and weigh it. A metering hopper discharge valve 6 is installed at the lower end of the metering hopper 4. The metering hopper discharge valve 6 is inclined towards the center of the frame 1 to collect the falling material for batching and mixing.
[0026] In this embodiment, the upper end of the negative pressure suction hopper 2 is provided with a negative pressure pipe 21, which is connected to the pneumatic conveying pipeline. The lower end of the negative pressure suction hopper 2 is provided with a conical guide cylinder 22. The lower end of the guide cylinder 22 is fitted with an air guide duct 23. An air guide hole 24 is opened on one side of the air guide duct 23. The air guide hole 24 is connected to a negative pressure device through an air duct. The material falls from the guide cylinder 22 into the buffer hopper 3.
[0027] The upper end of the buffer hopper 3 is open to receive the material guided down by the negative pressure suction hopper 2. Buffer frame plates 31 are provided on both sides of the buffer hopper 3. Slider blocks are provided on both sides of the buffer frame plates 31 and are slidably mounted on the corresponding slide rails of the frame 1. The frame 1 is also provided with a displacement cylinder 32 to drive the buffer hopper 3 to move. The output rod of the displacement cylinder 32 is fixedly connected to the buffer hopper 3 through a support plate to control the reciprocating movement of the buffer hopper 3 to adjust the receiving or discharging position.
[0028] In this embodiment, the buffer hopper discharge valve 5 includes a first valve seat 51, a fast discharge valve plate 52 slidably mounted on one side of the first valve seat 51, and a slow discharge valve plate 53 disposed on the other side of the first valve seat 51. A fast discharge cylinder 54 is provided on one side of the valve seat to control the movement of the fast discharge valve plate 52, and a slow discharge cylinder 55 is provided on the other side to control the movement of the slow discharge valve plate 53. Specifically, when the buffer hopper discharge valve 5 discharges material, the fast discharge valve plate 52 is first opened for rapid material discharge. Once a certain weight is reached, the fast discharge valve plate 52 is closed, and the slow discharge valve plate 53 is opened for slow material discharge, thus avoiding excessively fast discharge speed leading to overloading and improving weighing accuracy.
[0029] In this embodiment, sensor brackets 41 are provided around the metering hopper 4, and the weighing sensor 42 is installed on the sensor brackets 41 to detect the weight of the material falling from the buffer hopper 3. The lower end of the metering hopper 4 is an arc-shaped bucket structure to guide the material to the central area of the frame 1 and discharge the material through the metering hopper discharge valve 6.
[0030] The metering hopper discharge valve 6 includes an inclined second valve seat 61 and a second valve plate 62 slidably mounted on the upper end of the second valve seat 61. A valve control cylinder 63 is fixedly mounted on the outer side of the upper end of the second valve seat 61 to drive the second valve plate 62 to move, so as to open the valve port through the valve control cylinder 63 and discharge the material.
[0031] In this embodiment, eight negative pressure suction hoppers 2 are arranged in a ring, four sets of buffer hoppers 3 are arranged corresponding to the negative pressure suction hoppers 2, and four sets of metering hoppers 4 are arranged corresponding to the buffer hoppers 3, so as to guide materials sequentially.
[0032] Specifically, the negative pressure suction hopper 2 uses wind power to convey materials and guide them into the buffer hopper 3. The buffer hopper 3 is used to accumulate materials. The buffer hopper 3 is equipped with upper and lower level sensors, respectively. When the upper level is reached, the negative pressure suction hopper 2 stops feeding; when the lower level is reached, the negative pressure suction hopper 2 starts feeding again to maintain material stability within the buffer hopper 3. After the metering hopper 4 is set with a specified weight, the buffer hopper discharge valve 5 introduces materials into the metering hopper 4. The weighing sensor 42 detects the weight of the materials in the metering hopper 4. Initially, the fast discharge valve plate is opened; after a certain weight is reached, the slow discharge valve plate is switched on to avoid excessively fast discharge leading to overloading and improve weighing accuracy. Once the metering hopper 4 reaches the specified weight, the buffer hopper discharge valve 5 closes. After the distributed metering hoppers 4 have weighed the specific materials, the lower end of the metering hoppers 4 guides the materials to the middle area of the frame 1 through the inclined metering hopper discharge valve 6, so that the materials can be collected and distributed through the distributed metering hoppers 4.
[0033] The device uses a buffer hopper 3 and a metering hopper 4 in combination to control the weight of the material in the metering hopper 4 and ensure the accuracy of the batching. The lower end of the metering hopper 4 is inclined towards the center of the frame 1 to facilitate the collection of material.
