Description

Technical Field

[0001] This utility model relates to the field of tea production technology, and in particular to a tea mesh belt cooling conveyor. Background Technology

[0002] After the tea leaves are processed, the temperature is very high, requiring rapid cooling. Otherwise, the polyphenols and other components in the tea leaves will oxidize, causing the green tea to turn black and its taste to deteriorate. Currently, most tea leaves are cooled by spreading them directly on a mesh conveyor belt and cooling them with fans during transportation. However, this method tends to result in the surface tea leaves being cooled more quickly by the air blowing, while the tea leaves piled at the bottom cool slowly, leading to uneven cooling and affecting the overall cooling effect.

[0003] Therefore, a tea mesh belt cooling conveyor is proposed. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To overcome the shortcomings of existing technologies, a tea mesh belt cooling conveyor is proposed to solve the problems of uneven cooling and poor cooling effect of current mesh belt tea conveyors, which affect the quality of the tea.

[0006] (2) Technical solution

[0007] This utility model is achieved through the following technical solution: This utility model proposes a tea mesh belt cooling conveyor, including a cooling box. Inside the cooling box, rotating rollers are connected by bearings, and a conveyor belt is connected between the rotating rollers. A drive motor is installed at one end of the outside of the cooling box and connected to one of the rotating rollers.

[0008] The cooling box is equipped with a row of fans at the upper end of the conveyor belt;

[0009] The cooling box is located at the upper end of the conveyor belt and is connected to a row of rotating rods via bearings. Several agitating rods are staggered on the outer side of the rotating rods. A motor is installed at the top of the cooling box, and the output end of the motor is connected to the rotating rods via a gear transmission mechanism.

[0010] Furthermore, side guards made of soft rubber material are provided on both sides of the conveyor belt.

[0011] Furthermore, the gear transmission mechanism includes two driven wheels located on the protrusion of the rotating rod, and a driving wheel located at the output end of the motor. The driving wheel is connected to one of the driven wheels via a first belt, and the other driven wheels of the rotating rod are connected to each other via a second belt.

[0012] Furthermore, the front end of the cooling box is provided with a through push-pull groove located in the middle of the conveyor belt, and a collection frame is slidably connected inside the push-pull groove. Inside the cooling box, at the push-pull groove, there are several load-bearing strips connected to the collection frame.

[0013] Furthermore, an air blowing pipe is arranged inside the conveyor belt at the upper end of the collection frame, and several nozzles are provided at the upper end of the air blowing pipe. A blower is installed at the bottom of the cooling box, and the output end of the blower is connected to the air blowing pipe through an air pipe passing through one side of the cooling box.

[0014] Furthermore, the upper end of the hair dryer is provided with a partition that connects to the cooling box.

[0015] Furthermore, an observation window and a control panel are respectively installed on the outside of the cooling box.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model has the following advantages:

[0018] 1. In this utility model, after the tea leaves are placed on the conveyor belt, the conveyor belt is rotated by the drive motor, which moves the tea leaves into the cooling box. The tea leaves are cooled down by the action of a row of fans at the top, so that the tea leaves can be cooled down quickly and avoid the slow efficiency of natural cooling.

[0019] 2. In this utility model, the motor drives the drive wheel, which in turn drives a rotating rod to rotate under the action of the first belt. With the driven wheels connected by the second belt, all the rotating rods are subjected to force and rotate, which drives the stirring rod to turn the tea leaves on the conveyor belt. This turns the tea leaves at the bottom out for cooling, preventing the upper surface of the tea leaves from cooling quickly while the lower surface of the tea leaves cools slowly, resulting in uneven cooling. This makes the cooling effect more uniform, faster and better.

[0020] 3. In this utility model, by placing a collection frame inside the conveyor belt, the tea leaves generated during the transmission process can be collected, avoiding the scattering of the leaves and the resulting difficulty in subsequent cleaning, thus making the work more efficient.

[0021] 4. In this utility model, the blower works to blow air into the air pipe through the air pipe, and then sprays air onto the conveyor belt through the nozzle, which can cool the tea leaves at the bottom, resulting in a better cooling effect. Attached Figure Description

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0029] Please see Figure 1-Figure 4 This utility model provides a tea mesh belt cooling conveyor, including a cooling box 1, which allows tea to be cooled inside, making the airflow more concentrated for cooling. An observation window 2 and a control panel 3 are respectively installed on the outside of the cooling box 1. The observation window 2 facilitates observation of the tea inside the cooling box 1, and the control panel 3 facilitates operation of the electrical components, making operation more convenient. Inside the cooling box 1, rotating rollers 10 are connected via bearings, and a conveyor belt 4 is connected between the rotating rollers 10. A drive motor 113 is installed at one end of the outside of the cooling box 1 and connected to one of the rotating rollers 10. When the drive motor 113 drives the rotating rollers 10 to rotate, the conveyor belt 4 moves the tea, facilitating the tea to enter the cooling box 1 for cooling. Side guards 11 made of soft rubber material are provided on both sides of the conveyor belt 4 to prevent the tea from being squeezed into the gaps when it is turned over.

[0030] A row of fans 8 is installed at the upper end of the conveyor belt 4 in the cooling box 1 to cool the incoming tea leaves. A row of rotating rods 17 is connected to the upper end of the conveyor belt 4 in the cooling box 1 via bearings. Several agitating rods 18 are staggered on the outer side of the rotating rods 17. The staggered arrangement of the agitating rods 18 allows for the agitation of tea leaves at different locations, ensuring all tea leaves are turned over and preventing any from being missed, thus improving the cooling effect. A motor 9 is installed at the top of the cooling box 1, and the output end of the motor 9 is connected to the rotating rods 17 via a gear transmission mechanism. The gear transmission mechanism includes... The rotating rod 17 has two driven wheels 19 at its protrusion and a driving wheel 110 at the output end of the motor 9. The driving wheel 110 is connected to one of the driven wheels 19 via a first belt 111, and the other driven wheels 19 of the rotating rod 17 are connected to each other via a second belt 112. This allows the rotating rod 17 to rotate when the motor 9 connects the driving wheel 110 and the driven wheel 19 via the first belt 111. When the rotating rod 17 rotates, it drives the other driven wheels 19 to rotate under the action of the second belt 112, thereby achieving the purpose of turning the tea leaves by rotating the entire rod.

[0031] Preferably, the front end of the cooling box 1 is provided with a through push-pull groove 5 located in the middle of the conveyor belt 4, and a collection frame 6 is slidably connected inside the push-pull groove 5. This facilitates the pulling out of the collection frame 6 inside the push-pull groove 5, and the collection frame 6 facilitates the collection of tea leaves, avoiding the scattering of leaves and the resulting cleaning difficulties. Inside the cooling box 1, at the push-pull groove 5, there are several load-bearing bars 12 connected to the collection frame 6. The load-bearing bars 12 provide better support and stability for the collection frame 6. Inside the conveyor belt 4, at the upper end of the collection frame 6, there are air blowing pipes 15, and at the upper end of the air blowing pipes 15, there are several nozzles 16 for cooling. A blower 13 is installed at the bottom of the interior of the box 1. The output end of the blower 13 is connected to the air pipe 15 through the air pipe 14 through one side of the cooling box 1. Under the action of the blower 13, the nozzle 16 at the upper end of the air pipe 15 sprays air onto the tea leaves at the bottom, resulting in better cooling effect. The air pipe 15 is located at the upper end of the collection frame 6 to avoid interference. The air pipe 14 passes through the other side of the opening of the push-pull groove 5 to avoid obstructing the pulling out. A partition 7 is provided at the upper end of the blower 13 and connected to the cooling box 1 to prevent debris from falling down and being sucked into the blower 13.

[0032] Working principle: In use, first connect the control panel 3, fan 8, motor 9, blower 13 and drive motor 113 to an external power source. Then, drive motor 113 drives rotating roller 10 to rotate conveyor belt 4, thereby transporting the tea leaves placed at the top to the cooling box 1. At the same time, fan 8 works to cool the tea leaves on conveyor belt 4. Motor 9 drives drive wheel 110 to drive first belt 111 to drive a driven wheel 19 to rotate. Through second belt 112, all driven wheels 19 drive rotating rod 17 to rotate stirring rod 18 to turn the tea leaves, making the tea leaves cool more evenly. At the same time, blower 13 blows air through air pipe 14 and nozzle 16 at the top of air pipe 15 to cool the tea leaves at the bottom of conveyor belt 4, thus completing the work.
