[0002] In industrial production, we often encounter situations where multiple material ratios need to be controlled. In most cases, workers weigh different raw materials according to the required ratios, then add the weighed raw materials into the insulation bucket in turn, and finally obtain the finished product after a series of processes such as stirring and mixing. In this process, not only does it require the cooperation of multiple workers, which is labor-intensive, but it is also easily affected by the proficiency of the workers, resulting in low batching accuracy, which affects the quality of the final product. Summary of the invention

[0003] In order to overcome the above-mentioned shortcomings, the purpose of the present invention is to provide a multi-station ingredient weighing system, which realizes the automatic weighing and preparation of multiple materials, which not only reduces the labor intensity of workers, avoids the problem of low proportioning accuracy caused by human factors, but also improves production efficiency.

[0004] In order to achieve the above purpose, the technical solution adopted by the present invention is: a multi-station ingredient weighing system, including a frame, on which a liquid weighing device and a powder weighing device are arranged side by side, a mixing device fixedly connected to the frame is provided below the liquid weighing device, and the mixing device includes a mixing bin, and the upper end of the mixing bin is respectively provided with a liquid feed port corresponding to the liquid weighing device and a powder feed port corresponding to the powder weighing device.

[0005] The liquid weighing device comprises a plurality of liquid storage tanks arranged side by side, each of which is provided with a corresponding liquid weighing bucket below the liquid storage tank, and the lower ends of the liquid weighing buckets are provided with a confluence assembly connected with the liquid feed port.

[0006] The powder weighing device comprises a plurality of powder storage tanks arranged side by side, a powder weighing box which can move laterally along the frame is arranged below the powder storage tank; a weighing box inlet is arranged at the upper end of the powder weighing box, and a weighing box outlet is arranged at the lower end. A telescopic tube assembly matching the powder feed inlet is arranged at the weighing box outlet.

[0007] A mixing rod for stirring materials is arranged in the mixing bin, and a heating component for heating materials is arranged on the side wall.

[0008] The beneficial effects of the present invention are as follows: separate storage of liquid materials is achieved through multiple liquid storage tanks, and separate quantitative weighing of liquid materials is achieved through the setting of one-to-one corresponding liquid storage tanks and liquid weighing hoppers; multiple weighed liquid materials are introduced into the liquid feed port through the setting of the confluence component; separate storage of powder materials is achieved through the powder storage tank, and the movable powder weighing box can be moved to the bottom of any powder storage tank and above the powder feed port; the powder material in the powder storage tank is introduced into the powder weighing box for weighing through the powder weighing feed port; the weighed powder material is introduced into the powder feed port through the weighing box outlet; the weighing box outlet and the powder feed port are connected through the telescopic tube assembly; the powder material and liquid material are stirred and mixed through the mixing rod, and the mixing bin is heated and kept warm through the heating component, thereby ensuring sufficient mixing of the powder material and liquid material.

When the inner feed pipe moves downward, the lower end of the inner feed pipe abuts against the baffle and drives the baffle to rotate and open along the hinge position, at which time the powder material enters from the inner feed pipe onto the baffle and enters the mixing bin along the baffle; when the powder material is put in, the baffle covers the lower end surface of the outer feed pipe under the action of the spring hinge to close the powder feed port, and at this time the inner feed pipe moves upward along the outer feed pipe. The baffle is used to close the mixing bin to prevent dust from being generated during material mixing and materials from escaping from the powder feed port; the baffle is opened by the inner feed tube that can move up and down, so that the powder material enters the mixing bin from the inner feed tube along the baffle, and the guiding effect of the baffle further reduces the dust from escaping from the inner feed tube during feeding; the automatic closing of the baffle is achieved by the spring hinge.

[0012] Furthermore, the upper end of the inner discharge tube is provided with a funnel-shaped opening, and the radial dimension of the upper end of the funnel-shaped opening is larger than the radial dimension of the outlet of the weighing box. The funnel-shaped opening having a radial dimension larger than the outlet of the weighing box allows all the materials discharged from the split weighing outlet to enter the inner discharge tube, thereby avoiding material loss.

[0013] Furthermore, the heating assembly includes a heating layer and a heat preservation layer which are sequentially sleeved on the outer wall of the mixing bin, and a temperature sensor is also fixedly connected to the inner wall of the mixing bin. The heating layer heats the mixing bin, the heat preservation layer suppresses the loss of heat, and the temperature sensor monitors the temperature in the mixing bin in real time.
