Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tea making, in particular to a storage and discharging device for tea raw materials. Background Art
[0002] In the modern tea industry, traditional milk tea shops are the inheritors of classic culture and important places for consumers to relax in their daily lives. The way they store and use tea directly affects the quality of tea, brewing efficiency and customer experience. Traditionally, tea is usually stored in sealed tea storage tanks to maintain its freshness and aroma. However, when it is necessary to brew tea, shop assistants often need to manually open the opening at the top of the tea storage tank and grab the tea leaves manually. This process is not only inefficient and increases labor costs, but it is also easy to introduce hand bacteria or other contaminants during the grabbing process, posing a threat to the purity of the tea, and thus affecting the overall quality of the tea.
[0003] In order to improve this situation, some milk tea shops have begun to try to adopt a more automated tea discharging system. One of the designs is to set an automatically opened and closed discharging port at the bottom of the tea storage tank. The original intention of this design was to reduce human contact, improve hygiene standards, and enhance the convenience of tea leaves. However, in actual application, this design also exposed some significant problems. Specifically, when the discharging port is designed to be too large, the discharging speed of the tea leaves is difficult to control, which may cause a large amount of tea leaves to pour out in a short period of time, which not only increases the difficulty of subsequent dosage, but also may cause waste of tea leaves and a decrease in quality. If the discharging port is designed to be too narrow, the tea leaves are easily blocked at the discharging port, affecting the normal discharging of the tea leaves, and even requiring frequent manual intervention to clean up, which in turn reduces the efficiency and reliability of the automation system.
[0004] Therefore, developing a new tea storage and discharging system that can effectively avoid tea contamination, improve the efficiency of tea use, and accurately control the discharging speed and prevent blockage has become a technical problem that needs to be solved urgently in the current milk tea industry. This patent is proposed in this context, aiming to solve the deficiencies in the existing technology through innovative design and provide a more efficient, hygienic and intelligent solution for tea management in milk tea shops.

[0047] See Figures 1 to 3, the present utility model provides a storage and discharging device for tea drink raw materials, which includes a tea storage tank 1 for storing tea drink raw materials. A tank outlet is provided at the bottom of the tea storage tank 1. The device further includes a discharging mechanism 2 and a driving mechanism 3. The discharging mechanism 2 includes a discharging seat 21 and a spiral conveying rod 22. A conveying channel 211 is provided in the discharging seat 21. The upper end of the conveying channel 211 has a feeding port 212, and the feeding port 212 is communicated with the tank outlet of the tea storage tank 1. A discharging port 213 is provided on the bottom surface or the side wall surface of the conveying channel 211. The discharging seat 21 further has a blanking port 214 communicated with the discharging port 213. The spiral conveying rod 22 includes an intermediate rotating shaft 222 and conveying blades 221. The conveying blades 221 extend spirally around the intermediate rotating shaft 222 and are fixed to the intermediate rotating shaft 222. The conveying blades 221 are arranged in the conveying channel 211. The axis of the spiral conveying rod 22 is arranged vertically or obliquely. When it is oblique, the angle with the vertical direction should not be too large, preferably 0-20°; the driving mechanism 3 is connected to the intermediate rotating shaft 222 and can drive the intermediate rotating shaft 222 to rotate.
[0048] The main working principle of the storage and discharging device involved in the present utility model is as follows: Various tea drink raw materials (such as tea leaves, chrysanthemum tea, blended tea, etc.) can be stored in the tea storage tank 1 and automatically fall into the conveying channel 211 through the tank outlet and the feeding port 212. The conveying channel 211 can be a vertically extending channel or a slightly inclined extending channel deviating from the vertical direction. The gap between the conveying blades 221 of the spiral conveying rod 22 and the side wall surface of the conveying channel 211 is set according to the specific situation of the tea drink raw materials. Preferably, the gap is 1-4 mm to prevent the tea drink raw materials from entering the gap and directly falling through the gap. When the spiral conveying rod 22 does not rotate, the tea drink raw materials will not be conveyed out. When it is necessary to discharge the tea drink raw materials, the driving mechanism 3 drives the spiral conveying rod 22 to rotate. The spiral conveying blades 221 output the tea drink raw materials downward, and the raw materials fall out of the conveying channel 211 from the discharging port 213 and finally go out through the blanking port 214. When it is necessary to stop the conveying, the rotation of the spiral conveying rod 22 is stopped. Therefore, by controlling the rotation of the spiral conveying rod 22, the automatic discharging and stopping of the tea drink raw materials can be controlled, and the discharging speed can also be controlled. Compared with the conventional outlet design of the existing tea storage tank 1, the tank outlet, the feeding port 212 and the discharging port 213 in the present utility model can be made relatively large, effectively avoiding the blockage problem of the tea drink raw materials.
[0049] See Figures 1 to 4 , the following further illustrates the present utility model with a specific embodiment:

The difference between the radius R of the conveying channel 211 and the radius r of the conveying blades 221 is 1 to 4 mm, so that the gap between the conveying blades 221 and the side wall surface of the conveying channel 211 is 1 to 4 mm, which can prevent the tea drink raw materials from entering the gap and ensure the stable output of the tea drink raw materials. Of course, in other embodiments, the cross-sectional shape of the conveying channel 211 can also be elliptical, polygonal, etc., as long as it is ensured that the gap between the conveying blades 221 and the side wall surface of the conveying channel 211 is not large enough to allow the tea drink raw materials to enter and fall.
[0051] In this embodiment, refer to Figure 3 , as a preferred design, the axes of both the conveying channel 211 and the spiral conveying rod 22 are vertically arranged, and the upper end of the conveying channel 211 is an open structure, which forms the feed inlet 212, so as to ensure that the feed inlet 212 has a large cross-sectional area.

And an intermediate channel communicating the feeding port 212 and the tank outlet is provided in the upper fixing plate 42 for the smooth passage of the tea drink raw materials. The lower end of the intermediate rotating shaft 222 of the screw conveyor 22 is rotatably installed on the lower fixing plate 41 to keep the intermediate rotating shaft 222 stable. And a bearing 5 is provided between the intermediate rotating shaft 222 and the lower fixing plate 41 to ensure the stable rotation of the intermediate rotating shaft 222. The driving mechanism 3 is installed on the lower fixing plate 41.
[0054] In this embodiment, refer to Figure 3 and Figure 4 , as a preferred design, the upper fixing plate 42 further has a connecting member 421 located in the intermediate channel. The upper end of the intermediate rotating shaft 222 is rotatably installed in the connecting member 421, thereby stabilizing the upper end position of the intermediate rotating shaft 222 and further improving the working stability of the screw conveyor 22. A bearing 5 is preferably provided between the intermediate rotating shaft 222 and the connecting member 421 to ensure the stable rotation of the intermediate rotating shaft 222. In other embodiments, the upper and lower ends of the intermediate rotating shaft 222 can also be installed in other suitable ways. The driving mechanism 3 can also be connected to the upper end of the intermediate rotating shaft 222. At this time, the intermediate rotating shaft 222 can extend upward and extend out of the tea storage tank 1 as long as it does not affect the discharging of the tea drink raw materials.
[0055] In this embodiment, refer to Figure 2 and Figure 3 , as a preferred design, the driving mechanism 3 includes a motor 31, a transmission belt 33 and two belt pulleys 32. The two belt pulleys 32 are respectively coaxially fixed on the intermediate rotating shaft 222 and the output shaft of the motor 31. The transmission belt 33 connects the two belt pulleys 32. When the motor 31 rotates, the intermediate rotating shaft 222 is driven to rotate through the transmission belt 33 and the two belt pulleys 32. In other embodiments, the driving mechanism 3 can also adopt other suitable structures.
[0056] In this embodiment, refer to Figure 1 and Figure 3, As a preferred design, the tea storage can 1 is made of transparent acrylic board material, which can well observe the internal storage volume. The tea storage can 1 can also be made of other materials and provided with a visualization window. The top of the tea storage can 1 is provided with an openable and closable top cover 11 for adding tea drink raw materials. The bottom of the tea storage can 1 is an open mouth and forms a can outlet, and the shape and size of the can outlet are the same as or similar to the shape and size of the feed inlet 212 at the upper end of the conveying channel 211, so as to ensure that the can outlet has a large cross-sectional area.

When the spiral conveyor 22 rotates to convey and drop the tea drink raw materials into the container, weighing is carried out by the electronic weighing module, and the weight signal is transmitted to the control mechanism. When the weighed tea drink raw materials reach the required weight, the control mechanism controls the driving mechanism 3 to automatically stop driving. Moreover, according to the weight measured by the electronic weighing module, when the weighed tea drink raw materials are close to the required weight, the control mechanism controls the driving mechanism 3 to gradually decelerate and gradually reduce the rotation speed of the spiral conveyor 22, so as to ensure that the spiral conveyor 22 stops in time when the required weight is reached and avoid excessive output of tea drink raw materials. Among them, the control mechanism can adopt the existing structure, specifically, a PLC controller can be adopted and configured with corresponding electrical components. The control mechanism has functions such as data storage, calculation and analysis, and instruction sending, and can control the device to automatically execute the output work.

[0060] In summary, the present utility model effectively overcomes various shortcomings in the prior art and has high industrial utilization value.
