Description

Technical Field

[0001] This utility model belongs to the technical field of batching equipment, and in particular relates to a precise batching and feeding device. Background Technology

[0002] Precision batching equipment refers to devices used on automated production lines to accurately measure and dispense various raw materials. These devices typically include high-precision weighing sensors, automatic control systems, mixing equipment, and other auxiliary facilities. They can complete the batching process according to preset formula requirements, ensuring consistent product quality and maximizing production efficiency. Precision batching equipment is widely used in industries such as chemical, food, pharmaceutical, and rubber and plastic products, and is an important component of modern industrial automation. However, it still has the following drawbacks in practical use:

[0003] During the batching process, materials are usually transported directly to the silo through an external conveying structure. During the conveying process, the material is directly driven by the spiral blades, which will generate dust at the conveying location. This results in a large amount of dust around the feeding device during operation, affecting the safety of the working environment.

[0004] During the batching process, different materials are directly conveyed to the receiving equipment through different conveying devices, resulting in multiple steps required for batching, a lengthy workflow, and inconvenient operation. Utility Model Content

[0005] The purpose of this utility model is to provide a precise batching and feeding device. By setting up a support platform, a hopper, a vacuum feeder, a drive motor, and a receiving hopper, it solves the problems of dust pollution during material conveying and the inconvenience of operation due to the many batching steps.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a precision batching and feeding device, comprising a support platform, a hopper, a vacuum feeder, a drive motor, and a receiving hopper. Three hoppers are arranged in a circular array above the top of the support platform. A vacuum feeder is fixed to the top of each hopper, and the output end of the vacuum feeder is fixedly connected to a discharge pipe, which is fixedly inserted through the top of the hopper. A mounting frame is fixed to the lower periphery of each hopper, and a drive motor is fixed to the outer side of the mounting frame. A drive shaft is fixed to the output end of the drive motor, and the drive shaft is inserted through the mounting frame and one side of the hopper. A weighing module is fixed in a circular array at the bottom of the mounting frame. A receiving hopper is fixed to the bottom of the support platform, and the top of the receiving hopper is open. During operation, the support platform supports the hoppers and the vacuum feeder. The hoppers temporarily store the raw materials for batching, the vacuum feeder transports the raw materials into the hoppers, the drive motor drives the drive shaft to rotate, and the receiving hopper collects the material output from the hoppers.

[0008] Furthermore, the support platform has three vertically arranged movable holes in a circular array inside, which are located inside the receiving hopper. Support legs are fixed at the four corners of the bottom of the support platform, and the support platform is movably connected to the output pipe through the movable holes.

[0009] Furthermore, the bottom end of the silo is fixedly connected to a central hopper, and the output end of the central hopper is fixedly connected to an output pipe. The three output pipes are respectively inserted into three movable holes. An electric control valve is fixed around the output pipe above the support platform. The silo concentrates and outputs the material in it to the output pipe through the central hopper, and controls the on / off of the output pipe through the electric control valve.

[0010] Furthermore, a support column is fixed to the bottom of the weighing module, and the bottom end of the support column is fixed to the top of the support platform. When the weighing module is working, the support column supports the hopper on the top of the support platform.

[0011] Furthermore, a feeding pipe is fixedly connected to one side of the vacuum feeder, and a rotating frame is fixed to the end of the drive shaft located inside the hopper. The vacuum feeder conveys the material through the feeding pipe, and the rotating frame disperses the material in the hopper when it rotates.

[0012] Furthermore, a corrugated pipe is fixed to the output end of the receiving hopper, and a discharge pipe is fixedly connected to the bottom end of the corrugated pipe. The receiving hopper conveys the material received therein to the discharge pipe through the corrugated pipe.

[0013] This utility model has the following beneficial effects:

[0014] This invention solves the problem of dust pollution during material conveying in the batching process by setting up a support platform, a hopper, a vacuum feeder, a drive motor, and a receiving hopper. After the material is drawn in by the vacuum feeder, it is conveyed to the hopper through the discharge pipe, so that a certain amount of material is stored in the hopper. At the same time, the weight of the material in the hopper is weighed by a weighing module, and the weight data is transmitted to an external operating platform to confirm the weight of the material in the hopper. During batching, after the solenoid valve is started, the drive motor is turned on. The drive motor drives the drive shaft to rotate. The rotation of the drive shaft drives the rotating frame to rotate. The rotation of the rotating frame disperses the material in the hopper and the bin, so that the material is smoothly conveyed to the receiving hopper through the output pipe. When the material in the hopper has decreased to a suitable weight, the solenoid valve is closed to stop the material conveying. This reduces the steps that generate dust in the overall batching and conveying process, thereby reducing environmental dust pollution.

[0015] This invention solves the problem of multiple steps and inconvenient operation in the batching process by setting up a support platform, silos, and receiving hoppers. When batching materials, the receiving device is first pushed under the support platform. Then, the corrugated pipe is bent, and the end of the discharge pipe is inserted into the receiving device. Batching then begins. After batching, the material is conveyed from the discharge pipe to the receiving hopper. After being collected in the receiving hopper, it is conveyed through the corrugated pipe to the discharge pipe, and then through the discharge pipe to the receiving device. After receiving, the discharge pipe is pulled out, and one batching operation is completed. Multiple batching silos are concentrated on one support platform, and the materials are finally combined through the receiving hopper, eliminating the need for multiple batching steps and making the operation more convenient.

Three hoppers 2 are arranged in a circular array above the top of the support platform 1. When the support platform 1 is working, the hoppers 2 are supported on it to facilitate material feeding. The hoppers 2 temporarily store the raw materials for feeding. A vacuum feeder 3 is fixed to the top of each hopper 2. The vacuum feeder 3 sucks in the material and transports it into the hopper 2. The output end of the vacuum feeder 3 is fixedly connected to a discharge pipe 302, which is fixedly installed at the top of the hopper 2. When the vacuum feeder 3 is working, it draws in the material and transports it into the hopper 2 through the discharge pipe 302. A fixed frame 201 is fixed to the lower part of the perimeter. The hopper 2 is connected to the drive motor 4 and the weighing module 202 through the fixed frame 201. The drive motor 4 is fixed to the outside of the fixed frame 201. The output end of the drive motor 4 is fixed to the drive shaft 401. The drive shaft 401 is inserted through the fixed frame 201 and the hopper 2 on one side. The drive motor 4 drives the drive shaft 401 to rotate, which drives the rotating frame 402 to rotate. The weighing module 202 is fixed in a ring array at the bottom of the fixed frame 201. The weighing module 202 weighs the hopper 2, the vacuum feeder 3, and the material entering the hopper 2. The bottom of the support platform 1 is fixed with a receiving hopper 5. The top of the receiving hopper 5 is open. The material output by the proportioning is contained in the receiving hopper 5.

[0027] Specifically, the support platform 1 has three vertically arranged movable holes 101 in a circular array inside. The movable holes 101 are located inside the receiving hopper 5.

[0028] Furthermore, the bottom end of the silo 2 is fixedly connected to a central hopper 204, and the output end of the central hopper 204 is fixedly connected to an output pipe 205. The three output pipes 205 are respectively inserted into three movable holes 101. An electric control valve 206 is fixedly installed around the output pipe 205 above the support platform 1. When the silo 2 is working, the material in the silo 2 is concentratedly transported to the output pipe 205 through the central hopper 204, and the material in the central hopper 204 is transported to the receiving hopper 5 through the output pipe 205. The receiving hopper 5 concentrates the batched material.

[0029] Furthermore, a support column 203 is fixed to the bottom of the weighing module 202, and the bottom end of the support column 203 is fixed to the top of the support platform 1. The weighing module 202 supports the hopper 2 and the vacuum feeder 3 on it on the support platform 1 through the support column 203.

[0030] The operation process of this embodiment is as follows: During operation, after the material is drawn in by the vacuum feeder 3, the material is transported to the silo 2 through the discharge pipe 302, so that the silo 2 stores a certain amount of material. At the same time, the weight of the material in the silo 2 is weighed by the weighing module 202, and the weight data is transmitted to the external operating table to determine the weight of the material in the silo 2. During batching, after starting the solenoid valve 206, the drive motor 4 is turned on at the same time. The drive motor 4 drives the drive shaft 401 to rotate. Through the rotation of the drive shaft 401, the rotating frame 402 is driven to rotate. Through the rotation of the rotating frame 402, the material in the collection hopper 204 and the silo 2 is dispersed, so that the material is smoothly transported to the receiving hopper 5 through the output pipe 205. When the material in the silo 2 has reduced to a suitable weight, the solenoid valve 206 is closed to stop the material conveying and accurately batching is performed.
