Technical Field
[0001] The invention relates to the field of tea processing machinery, in particular to a small tea blending and stacking machine. Background Art
[0002] In tea processing, in order to improve the uniformity of the taste and aroma of tea, the tea needs to be blended and piled before packaging after the tea processing is completed.

Driven by the driving device, the tea leaves fall onto the bulk feeder and are thrown out in the reverse direction under the action of the bulk feeder. The tea leaves after being thrown out fall onto the mixing hopper and are turned over and mixed under the action of the reverse guide ribs and slide downward along the reverse guide ribs.
[0008] For preliminary mixing, a feed hopper is provided at the feed end of the mixing barrel, and a drop inclined pipe is provided at the bottom of the feed hopper.

[0009] In order to achieve batching, at least one batching conveyor belt is provided; each of the raw material conveyor belts can independently adjust the discharge flow rate.
[0010] In order to achieve mixing of tea leaves while shuffling them on the bulk feeder, a group of positive guide ribs are provided on the bulk feeder, and the positive guide ribs extend downwardly from the upper part of the bulk feeder to the lower edge in a clockwise direction.

[0017] Beneficial effects of the present invention: The present invention completes the blending and stacking of tea leaves by cooperating with a blending conveyor belt and a mixing barrel. The structure occupies a small space as a whole and has a low cost. The present invention first spreads various tea leaves evenly on the blending conveyor belt according to a set ratio through multiple raw material conveyor belts, so that a multi-layer tea structure is formed on the blending conveyor belt, and then multiple mixing is performed through a mixing barrel, thereby improving the uniformity of tea mixing to achieve a uniform stacking effect. The present invention ensures the uniformity of tea mixing by designing the structure inside the mixing barrel. Specifically, an umbrella-shaped spreader is first used to rotate to spread the fallen tea leaves, and then the tea leaves are dropped into the mixing hopper for mixing. At the same time, the tea leaves are further mixed and scattered by combining the forward guide ribs on the spreader and the reverse guide ribs on the mixing hopper, thereby improving the uniformity of blending. In addition, an umbrella-shaped spreader is also provided below the discharge port of the mixing hopper to further scatter the fallen tea leaves, thereby further improving the uniformity of the mixed pile. At the same time, a falling inclined pipe is arranged in front of the mixing barrel, which can achieve the purpose of preliminary mixing, increase the number of times the tea leaves are mixed, and thus improve the final uniform stacking effect.

[0032] Example 1: Figures 1 to 11 As shown, a small tea blending and stacking machine includes a vertically arranged mixing barrel 1, a blending conveyor belt 5 connected to the feeding end of the mixing barrel 1, and a discharge conveyor belt 7 connected to the discharge end of the mixing barrel 1. Tea leaves are stacked and conveyed through the blending conveyor belt 5, and then mixed through the mixing barrel 1. After mixing, they are output and packaged through the discharge conveyor belt 7.
[0033] The following describes in detail the structure of each component and its connection relationship:
[0034] The blending conveyor belt 5 is provided with one, and a group of raw material conveyor belts 6 for feeding the blending conveyor belt 5 are arranged on both sides of the blending conveyor belt 5, and a storage hopper 61 is provided at the feeding end of the raw material conveyor belt 6, and the conveying speed of each raw material conveyor belt 6 can be adjusted. The discharge port of the storage hopper 61 is provided with a flow control valve 62, which can control the discharge amount of tea leaves, and the discharge flow rate of each raw material conveyor belt 6 is controlled by adjusting the flow control valve 62 and the conveying speed of the raw material conveyor belt 6, so as to control the discharge flow rate of each raw material conveyor belt 6, and various tea leaves are spread on the blending conveyor belt 5 through their respective raw material conveyor belts 6, so as to form a multi-layer tea structure on the blending conveyor belt 5 and send it to the feeding hopper 8. The blending conveyor belt 5 and the raw material conveyor belt 6 are both Z-shaped lifting conveyor belts, and the length of the horizontal section of the feeding end can be adjusted according to actual needs.
[0035] When the blending conveyor belt 5 is fed, the blending conveyor belt 5 is opened first, and then the first raw material conveyor belt 6 located at the front end of the blending conveyor belt 5 is started to spread the material on the blending conveyor belt 5. When the tea leaves output by the first raw material conveyor belt 6 are conveyed to below the discharge end of the second raw material conveyor belt 6, the second raw material conveyor belt 6 is opened to discharge the material, and the tea leaves on the second raw material conveyor belt 6 are stacked on the tea leaves output by the first raw material conveyor belt 6. By analogy, the remaining raw material conveyor belts 6 are started to discharge the material in turn.
[0036] The mixing barrel 1 includes a barrel frame 11 for supporting it above the discharge conveyor belt 7. A feed port 102 is provided above the mixing barrel 1, and a tea outlet 101 is provided at the bottom. A bulk feeder 2 is provided in the mixing barrel 1 below the feed port 102 and rotates in a counterclockwise direction. The bulk feeder 2 is an umbrella-shaped structure. The feed hopper 8 is located above the feed port 102. A drop-off inclined pipe 81 is provided at the bottom of the feed hopper 8. The discharge end of the drop-off inclined pipe 81 is located above the bulk feeder 2. The drop-off inclined pipe 81 is a variable diameter pipe structure with a large feed port diameter and a small discharge port diameter. Tea leaves are preliminarily mixed under the action of the drop-off inclined pipe 81.
[0037] A mixing hopper 3 is provided below the bulk feeder 2 for catching the tea leaves thrown out from the bulk feeder 2. The mixing hopper 3 is a trumpet-shaped structure with a large top and a small bottom, and collects the tea leaves falling on the mixing hopper 3. A drop opening is provided at the bottom of the bulk feeder 2, and the drop opening corresponds to the tea outlet 101 at the bottom of the mixing barrel 1. To ensure that the tea leaves thrown out from the bulk feeder 2 can accurately fall into the mixing hopper 3, the height of the lower edge of the bulk feeder 2 is lower than the height of the upper edge of the mixing hopper 3, and the maximum diameter of the bulk feeder 2 is smaller than the maximum diameter of the mixing hopper 3, that is, the bulk feeder 2 is placed in the mixing hopper 3.
[0038] In order to improve the mixing effect, a group of positive guide ribs 21 are provided on the bulk feeder 2, and the positive guide ribs 21 extend downward from the upper part of the bulk feeder 2 to the lower edge in a clockwise direction. Under the joint action of the positive guide ribs 21 and the counterclockwise rotation (reverse rotation) of the bulk feeder 2, the tea leaves are turned over and mixed while sliding down. In order to save the cost of the equipment, the mixing hopper 3 and the bulk feeder 2 share a driving device 4 and rotate in the same direction, that is, the mixing hopper 3 also rotates counterclockwise. Similarly, in order to further mix the materials, a group of reverse guide ribs 31 are provided in the mixing hopper 3, that is, the inclination direction of the reverse guide ribs 31 is opposite to the inclination direction of the positive guide ribs 21. At the same time, in order to further guide the mixing of the tea leaves, the cross-sections of the positive guide ribs 21 and the reverse guide ribs 31 are triangular structures, and the overall structure is small at the upper end and large at the lower end. Through the structural design of the present invention, the uniformity of the mixing can be improved, and the effect of blending and stacking can be improved. At the same time, the structure occupies a small space, has a simple structure, and is low in cost. In order to make the tea leaves fall evenly onto the discharge conveyor belt 7 , the tea outlet 101 is a rectangular outlet whose width is the same as the width of the discharge conveyor belt 7 , and the bottom opening diameter of the mixing hopper 3 is adapted to the width of the tea outlet 101 .
[0039] In order to realize the driving of the bulk material feeder 2 and the mixing hopper 3, and at the same time, taking into account the falling of materials and the cleanliness of tea leaves to avoid the tea leaves being contaminated during mixing, the specific structure of the driving device 4 is designed as follows.

In order to prevent the rotating shaft 41 from moving up and down, an upper limit sleeve 424 is provided on the rotating shaft 41 above the upper support bearing 421, and a lower limit sleeve 425 is provided below the lower support bearing 422. The upper limit sleeve 424 and the lower limit sleeve 425 are fixed on the rotating shaft 41 by welding or fixing screws 426. In order to prevent the oil in the lower support bearing 422 from contaminating the tea leaves or tea leaves from entering the lower support bearing 422 and affecting the normal operation of the rotating shaft 41, the rotating shaft 41 is located below the discharge port of the mixing hopper 3 and is also provided with an umbrella-shaped material distributor 5. The umbrella-shaped material distributor 5 covers the lower support bearing 422. While protecting the lower support bearing 422, the umbrella-shaped material distributor 5 can also further disperse the tea leaves, thereby further improving the uniformity of the mixed material pile.
[0042] To drive the rotating shaft 41, a motor mounting bracket 431 is provided at the upper end of the mixing barrel 1, and a driving motor 43 is installed on the motor mounting bracket 431.
