Description

Technical Field

[0001] This utility model belongs to the technical field of tea processing equipment, specifically relating to a tea wheel-type weighing and feeding mechanism. Background Technology

[0002] The current material discharge mechanism adopts a funnel-type discharge method. For example, the automatic feeding and dispensing machine with patent number CN202322165764.3 has a discharge structure that is achieved by opening and closing the covers on both sides.

[0003] However, during the tea feeding process, precise measurement is performed in grams, with an allowable tolerance range of ±0.2 grams. When the weight of the tea leaves in the hopper reaches the acceptable standard, the left cover will open, and the tea leaves will fall into the steam chamber, after which the cover will close. If a few extra tea leaves are fed, causing the weight to exceed the acceptable range, the right cover will open to discharge the substandard material, and then the cover will close again.

[0004] During actual use, the inventors discovered that these prior art technologies have at least the following technical problems:

[0005] Throughout the entire operation, the opening and closing of the lid is relatively rapid, whether discharging qualified or unqualified materials. This often results in some tea leaves remaining in the funnel after the material is discharged and the lid is closed. After feeding and discharging, or after multiple feeding and discharging operations, to ensure the accuracy of subsequent weighing, the weighing device needs to be zeroed and its parameters automatically recalibrated. If the tea leaves in the hopper are not completely discharged at this time, the weight of the tea leaves fed later will be too heavy after zeroing. In the subsequent pressing process, this weight deviation will cause the batch of products to be overweight, ultimately requiring scrapping. More seriously, continuous overweight conditions may also damage the mold and mechanical structure. Summary of the Invention

[0006] To overcome the aforementioned shortcomings, the inventors of this utility model, through long-term exploration, experimentation, and continuous efforts, have proposed a tea disc-type weighing and feeding mechanism. This mechanism can solve the problem in the prior art where residual material in the hopper affects weighing, leading to deviations in the weight of subsequent materials and causing product and equipment problems.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a tea wheel type weighing and feeding mechanism is provided, which includes a hopper, a support, a weight sensor and a rotary drive device. The weight sensor and the rotary drive device are mounted on the support. The hopper is fixedly connected to the output shaft of the rotary drive device. The hopper includes two turntables arranged opposite each other and a material support plate installed between the two turntables.

[0008] The further preferred technical scheme of the tea wheel disc type weighing and discharging mechanism is that the material receiving plates are four and are evenly arranged between the two rotating discs.

[0009] The further preferred technical scheme of the tea wheel disc type weighing and discharging mechanism is that the weight sensor is fixedly arranged at the bottom of the support.

[0010] The further preferred technical scheme of the tea wheel disc type weighing and discharging mechanism is that the rotating driving device is a motor.

[0011] The further preferred technical scheme of the tea wheel disc type weighing and discharging mechanism is that the rotating driving device is installed at the top of the support, and the output shaft of the rotating driving device is fixedly connected with the center of the hopper through the support.

[0012] The further preferred technical scheme of the tea wheel disc type weighing and discharging mechanism is that the support comprises a side plate and a bottom plate, and the side plate and the bottom plate are fixedly connected perpendicularly.

[0013] The further preferred technical scheme of the tea wheel disc type weighing and discharging mechanism is that it further comprises a fixing plate, the fixing plate is arranged on the support perpendicularly, one side of the fixing plate is fixedly connected with the side plate, and the other side of the fixing plate is fixedly connected with the bottom plate.

[0014] Compared with the prior art, the technical scheme of the present application has the following advantages / benefits:

[0015] The present application is provided with a hopper, a support, a weight sensor and a rotating driving device, the hopper comprises two oppositely arranged rotating discs and a plurality of material receiving plates arranged between the rotating discs, the hopper is divided into loading areas by the material receiving plates, and tea enters the loading areas when discharging. The gravity sensor weighs the hopper. The output shaft of the rotating driving device is fixedly connected with the hopper, if the weight is qualified, the hopper is driven by the rotating driving device to rotate in one direction, if the weight is unqualified, the hopper rotates in the other direction, thereby completing the discharging and sub-packaging. Compared with the prior art which needs to sequentially complete the steps of discharging, opening the cover, discharging and closing the cover, the present application completes the discharging under the action of gravity by rotating the hopper, omits the steps of opening and closing the cover, and the previous loading area can continue to discharge when discharging the next loading area, thereby prolonging the discharging time and preventing the tea from being blocked in the hopper, so that the weight sensor is not affected.

[0023] Embodiment:

[0024] A tea leaf wheel disc type weighing and discharging mechanism for packaging qualified weight tea leaves and unqualified weight tea leaves, comprising: a hopper 1, a support 2, a weight sensor 3, a rotary drive device 4, a fixed plate 5, a rotary disc 11 and a material receiving plate 12.

The fixing plate 5 is in a triangular structure, which is vertically fixed on the bracket 2, that is, one straight angle side of the fixing plate 5 is fixedly connected with the side plate 21, and the other straight angle side of the fixing plate 5 is fixedly connected with the bottom plate 22. The fixing plate 5 can form multidirectional support with the bracket 2, reduce local stress concentration, and because of the stable triangular structure of the fixing plate 5, the torsion resistance of the connecting part of the side plate 21 and the bottom plate 22 can be enhanced.

[0026] A weight sensor 3 is fixedly installed at the bottom of the bracket 2, which is used to detect the weight of tea in the hopper 1. A rotary driving device 4 is fixedly installed at the top of the bracket 2, which is a motor, and the output shaft of the rotary driving device 4 is fixedly connected with the center of the hopper 1 through the side plate 21 of the bracket 2, that is, the hopper 1 and the rotary driving device 4 are respectively arranged at two ends of the side plate 21, and the hopper 1 is driven to rotate around the center by the rotary driving device 4.

[0027] The hopper 1 is used to catch tea during discharging, which comprises a rotating disc 11 and a material receiving plate 12.

[0028] Working principle: The hopper 1 of the present application is evenly divided into multiple equal funnel-shaped structures by the material receiving plate 12, forming multiple loading areas. The tea enters the loading area, and the weight is weighed by the weight sensor 3. If the weight is qualified, the hopper 1 is rotated clockwise by a certain angle, and under the action of gravity, the tea can be poured into the container of the next process.

[0029] Use method: The tea enters the hopper 1, and the weight sensor 3 weighs. When it is detected that the weight is unqualified, the rotary driving device 4 is started to make the hopper 1 rotate counterclockwise by a certain angle. When it is detected that the weight is qualified, the rotary driving device 4 is started to make the hopper 1 rotate clockwise by the angle, and then the tea enters the hopper 1, and the above steps are continued to complete the sub-packaging of the tea.
