The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0026] To address the problems of high manpower consumption and low production efficiency associated with traditional manual weighing and mixing, this invention provides a weighing and mixing device. The device consists of a feeder, a feeding-type loss-in-weight scale, and a mixing hopper, fixedly mounted sequentially from top to bottom on the main frame. Multiple feeders and feeding-type loss-in-weight scales are arranged in a one-to-one configuration, spaced circumferentially along the mixing hopper, effectively improving space utilization and the device's feasibility. An industrial control computer is also fixedly mounted on the outside of the main frame, communicating and controlling with the feeder, feeding-type loss-in-weight scale, and mixing hopper. This enables automated execution of material handling, weighing, and mixing, improving production efficiency, reducing manpower requirements, and featuring a compact structure with high space utilization, reducing site requirements and enhancing feasibility.

[0027] Specifically, please refer to Figure 1 The figure shows a three-dimensional structural diagram of the weighing and mixing device in an embodiment of the present invention. It includes a main frame 100, and a feeder 200, a feeding loss-in-weight scale 300 and a mixing hopper 400 fixedly mounted on the main frame 100. The feeder 200, the feeding loss-in-weight scale 300 and the mixing hopper 400 are arranged sequentially from top to bottom to complete the material taking, weighing and mixing in sequence. After the mixing is completed, the mixing hopper 400 opens the bottom discharge port to discharge the material.

[0028] Multiple feeders 200 and feeder-type loss-in-weight scales 300 are provided and are arranged in a one-to-one correspondence. The feeders 200 and feeder-type loss-in-weight scales 300 are arranged at intervals along the circumference of the mixing hopper 400 to form a ring layout, which can improve the space utilization of the equipment, facilitate the balance of counterweight, and improve the overall structural stability of the weighing and mixing device.

[0029] An industrial control computer 500 is also fixedly installed on the outside of the main frame. The industrial control computer 500 is connected to the feeder 200, the feeder loss-in-weight scale 300 and the mixing hopper 400 for communication and control (not shown in the relevant wiring diagram). It is used to monitor and control the working status of the feeder 200, the feeder loss-in-weight scale 300 and the mixing hopper 400, so as to control the material taking and weighing of each feeder 200 and the feeder loss-in-weight scale 300 according to the set mixing ratio, and to control the mixing operation of the mixing hopper 400.

[0030] To facilitate the control of material feeding volume, this embodiment also includes a pneumatic butterfly valve 201. The pneumatic butterfly valve 201 is installed at the discharge port of the feeder 200 and is connected to the industrial control computer 500 for communication control. This allows the material to be temporarily stored in the feeder 200's hopper after feeding. After the previous batch of material is mixed, the pneumatic butterfly valve 201 is opened to feed the next batch of material. Furthermore, the temporary storage of material in the feeder 200's hopper ensures a more stable material flow rate from the feeder 200 to the loss-in-weight feeder 300, guaranteeing production efficiency. It also improves the control accuracy of material feeding, ensuring that the feed volume of the loss-in-weight feeder 300 remains within the set range, thereby ensuring the accuracy of weighing and feeding, and improving the mixing accuracy.

[0031] To facilitate the feeding of powdered materials, in this embodiment, as follows: Figure 2 As shown, the feeding machine 200 is a vacuum feeding machine. A vacuum pumping device 202 is also fixedly installed on the main frame 100. The vacuum pumping device 202 is connected to each vacuum feeding machine and is also connected to the industrial control computer 500 for communication and control. The industrial control computer 500 can monitor the material storage level in the feeding machine 200. When the material storage level is lower than the preset basic storage level, the vacuum pumping device 202 is controlled to operate, providing negative pressure to the vacuum feeding machine to extract the material. The vacuum pumping device 202 is also controlled to start when the weighing and mixing device is started.

[0032] Since this embodiment has multiple feeders 200, which share a single vacuum device 202, the types of materials corresponding to each feeder 200 are generally different, the required proportions are also different, the feeding amount is different, and the feeding frequency is different. In order to adapt to different feeding needs, control valves can be installed in the negative pressure suction pipe or feed pipe of each feeder 200, and the industrial control computer 500 can control each feeder 200 to independently feed and unload materials.

[0033] In a preferred embodiment, the feeding machine 200 in this embodiment is provided with 7 sets, which can realize the mixing operation of seven kinds of raw materials. For the mixing needs of fewer than seven kinds of raw materials, and for raw materials with a large mixing ratio, the number of feeding machines used for feeding the raw materials can be increased, reducing the feeding load of a single feeding machine. Moreover, each feeding machine 200 and the vacuum equipment 202 are evenly spaced along the circumference of the main frame 100, with a compact layout and high space utilization.

[0034] The vacuum pump 202 is positioned opposite the industrial control computer 500, which avoids obstruction by the industrial control computer 500 and facilitates the maintenance and debugging of the vacuum pump 202. Furthermore, there is no feeder-type loss-in-weight scale 300 directly below the vacuum pump 202, which can form an open window that provides a maintenance and operation window for the agitator 400 enclosed inside.

[0035] The projection of the main frame 100 onto the horizontal plane is a regular octagon. The feeding machine 200 and the vacuum equipment 202 are respectively set in the triangular sectors of the regular octagon, resulting in uniform weight distribution. The support columns of the main frame 100 are located at the corners of the regular octagon, ensuring overall support stability. The support columns of the main frame 100 can be fixed to the ground with expansion bolts, and the overall material can be stainless steel.

[0036] Vacuum equipment 202, such as a Roots blower, can meet the negative pressure requirements of a vacuum feeder at a low cost.

[0037] To facilitate the material feeding layout, in this embodiment, the feeding machine 200 is fixedly installed on the top plate 110 of the main frame 100, and the main structure of the feeding machine 200 is located in the space above the top plate 110, so that the feeding pipe of the feeding machine 200 can be arranged above, and the height of the main frame 100 can be reduced, saving the cost of the main frame 100.

[0038] The top plate 110 has a window structure 111 in the middle that is aligned with the mixing hopper 400. This can reduce the weight of the top plate 100 and allow the mixing hopper 400 inside to be observed through the window structure 111. It can also be used for the installation and maintenance of structural components such as the mixing shaft and bushing on the top of the mixing hopper 400.

[0039] To prevent debris from falling into the mixing hopper 400, in this embodiment, as follows: Figure 3 As shown, the mixing hopper 400 also includes a top cover 410, on which a plurality of feed openings 411 are provided at intervals along the circumference. The discharge port 301 of the feed type loss-in-weight scale 300 is connected to each feed opening 410 in a corresponding manner.

[0040] Corresponding to the surrounding layout of the feed-type loss-in-weight scale 300, the discharge port 301 of the feed-type loss-in-weight scale 300 is extended towards the center of the main frame 100, and the discharged material falls vertically into the mixing hopper 400.

[0041] The weighing and mixing device provided by this utility model has a feeder, a feeding-type loss-in-weight scale, and a mixing hopper fixedly installed on the main frame from top to bottom. Multiple feeders and feeding-type loss-in-weight scales are installed and arranged in a one-to-one correspondence. The feeders and feeding-type loss-in-weight scales are spaced apart along the circumference of the mixing hopper, which can effectively improve space utilization and enhance the feasibility of the equipment. An industrial control computer is also fixedly installed on the outside of the main frame. The industrial control computer is connected to the feeder, feeding-type loss-in-weight scale, and mixing hopper for communication and control, which can realize the automated execution of material handling, weighing, and mixing, improve production efficiency, reduce the demand for human resources, and has a compact structure and high space utilization, which can reduce the requirements for the site and improve feasibility.
