Description

Technical Field

[0001] The invention relates to the technical field of tea processing equipment, in particular to withering equipment for tea processing. Background Art

[0002] At present, the spreading and withering of tea leaves is usually carried out using spreading and withering equipment. The conveyor belt is used to transport the tea leaves to the drying board at a uniform speed, artificially creating a withering environment and accelerating the tea processing efficiency. However, the spreading of tea leaves is mostly one-time, and it is difficult to turn the tea leaves during the processing without manual labor. On the one hand, the accumulated tea leaves are not conducive to air flow to carry away moisture, and on the other hand, it is not convenient for the tea leaves to be fully withered. There are also cases of manual spreading, and the tea leaves can be turned manually during the withering process, but the degree of automation is limited. Therefore, we propose a withering equipment for tea processing. Summary of the Invention

DETAILED DESCRIPTION

[0016] See also Figure 1-9 The present invention provides a technical solution: a withering device for tea processing, comprising a frame 1, a heat circulation mechanism 2 for withering tea leaves, a tea feeding mechanism 3 for spreading tea leaves, and a conveying and spreading mechanism 4 for spreading tea leaves. The heat circulation mechanism 2 includes a housing 21, a lighting assembly 22, and a ventilation assembly 23. The housing 21 is mounted on the frame 1 and has an opening on its sidewall. The lighting assembly 22 is disposed within the housing 21 and utilizes light to accelerate the withering process of the tea leaves. The ventilation assembly 23 is disposed on the frame 1 and within the housing 21 and is used to exhaust air and reduce moisture in the housing 21. The ventilation assembly 23 is mounted on the frame 1 and is located inside the conveyor belt 41. The ventilation assembly 23 is a fan. The tea feeding mechanism 3 is installed on the top of the housing 21; See also Figure 1-3 , 6-7 The conveying and spreading mechanism 4 includes a conveyor belt 41, a spreading component 42, a driving component 43 and a magnetic driving component 44. The conveyor belt 41 is installed on the frame 1, and the driving component 43 is also installed on the frame 1 to drive the conveyor belt 41. The conveyor belt 41 mentioned here should also be equipped with at least two transmission rollers to form a transmission connection. The driving component 43 drives the transmission roller to rotate to drive the conveyor belt 41. In this application, in order to prevent the transmission roller from affecting the free movement of the spreading component 42, the transmission roller adopts a design of thick ends and thin middle. The transmission roller only contacts the edge of the conveyor belt 41 and is out of the motion range of the spreading component 42. As a well-known technology, it will not be repeated. The driving component 43 is electric. The conveyor belt 41 is provided with mounting holes 5 arranged at equal distances. The spreading component 42 is arranged in the mounting holes 5 for spreading tea leaves. The magnetic driving component 44 is arranged on the frame 1 and is on both sides of the conveyor belt 41. The tea leaves are flattened by the action of the magnetic driving spreading component 42, and one end of the conveyor belt 41 extends to the outside of the shell 21 for discharging after the tea leaves are withered.

[0017] See also Figure 1-2 4. The tea feeding mechanism 3 includes a material box 31, a material shifting assembly 32, and a discharging assembly 33. The material box 31 is installed at the opening on the top of the shell 21. The material box 31 is respectively provided with an inlet and a outlet. The material shifting assembly 32 is arranged in the material box 31 to disperse the tea leaves for smooth discharge. The discharging assembly 33 is arranged at the discharge port of the material box 31 and is on the upper side of the conveyor belt 41 to discharge the tea leaves in the material box 31.

[0018] See also Figure 9The discharging assembly 333 includes a roller 331, blades 332 and a runner 333. The roller 331 is movably connected to the side wall of the material box 31 through a bearing and is located at the discharge port of the material box 31. Several blades 332 are arranged on the side wall of the roller 331. The number of blades 332 is selected according to processing requirements. The more blades 332, the less material is discharged each time, and the corresponding tea leaves falling on the paving assembly 42 are less, that is, the spread tea leaves are thinner. One end of the roller 331 extends outside the material box 31 and is fixedly connected to the runner 333. A protrusion 6 is provided on the conveyor belt 41 at a position corresponding to the paving assembly 42. The protrusion 6 contacts the runner 333 and can use the conveyor belt 41 to drive the runner 333 to rotate and discharge the material. The setting of the protrusion 6 makes the roller 331 rotate only when the paving assembly 42 moves below it, so that the tea leaves can be accurately distributed. The tea leaves are then moved to the feed container 31 and the tea leaves are moved to the feed container 31. The tea leaves are then moved to the feed container 31 and the tea leaves are moved to the feed container 31. The tea leaves are then moved to the feed container 31 and the feed container 31 is moved to the feed container 31.

[0019] The spreading assembly 42 includes a spreading plate 421, a connecting rod 422 and a magnetic plate 423. The two ends of the spreading plate 421 are movably connected to the inner wall of the mounting hole 5 through the connecting rod 422. The spreading plate 421 is in the mounting hole 5 and can use the side wall of the mounting hole 5 to block the tea leaves and prevent them from escaping from the range of the spreading plate 421. Both ends of the spreading plate 421 are fixedly connected with a magnetic plate 423. The magnetic plate 423 is affected by the magnetic drive assembly 44 and can drive the spreading plate 421 to shake and spread the tea leaves evenly.

[0020] The paving plate 421 is a glass plate, and the paving plate 421 is provided with evenly distributed ventilation holes 8, and the upper surface of the paving plate 421 is provided with evenly distributed protrusions 9 to enhance the friction with the tea leaves. Figure 8 In order to ensure that the paving board 421 remains horizontal in a balanced state, the thickness of the paving board 421 increases from both sides to the middle.

[0021] Compared with the withering equipment in the prior art, this technical solution makes the tea spreading space on the conveyor belt into an independent unit, namely the spreading component 42. During the withering process, it is more convenient to use the shaking of the spreading plate 421 to turn the tea leaves without causing tea leaves to accumulate, thus solving the problems mentioned in the background technology.

[0022] The magnetic drive assembly 44 includes a mounting shell 441 and an electromagnet 442. The mounting shell 441 is mounted on the frame 1 and is parallel to the conveyor belt 41. Multiple electromagnets 442 are installed in the mounting shell 441. When the electromagnet 442 is energized, it can use magnetic force to drive the magnetic plate 423 to move.

[0023] The electromagnet 442 should be installed evenly along the extension direction of the mounting shell 441 to ensure that the magnetic plate 423 is always in the influence range of the electromagnet 442 when the conveyor belt 41 is running. Changing the direction and magnitude of the current of the electromagnet 442 can control the change of the magnetic force of the controller, and then drive the spreading plate 421 to shake rapidly through the magnetic plate 423. The shaking amplitude should ensure that the spreading plate 421 does not leave the range of the mounting hole 5 to prevent tea leaves from falling. The shaking amplitude of the spreading plate 421 is larger when turning the tea leaves than when shaking the tea leaves evenly.

[0024] The lighting assembly 22 includes a mounting plate 221, a strip hole 222 and a fluorescent lamp 223. The two mounting plates 221 are respectively mounted on the inner top wall of the outer shell 21 and the frame 1. The mounting plate 221 on the frame 1 is located on the inner side of the conveyor belt 41. Several strip holes 222 are opened at equal distances on the mounting plate 221, and the fluorescent lamp 223 is installed in the strip hole 222.

[0025] When the device is working, the fluorescent lamp 223 and the ventilation component 23 are turned on, the tea leaves to be processed are put into the material box 31, and the driving component 43 is started to drive the conveyor belt 41 to rotate. As the conveyor belt 41 rotates, the protrusion 6 contacts the runner 333 and drives the roller 331 to rotate so that the tea leaves fall on the paving board 421. As the runner 333 separates from the protrusion 6, the discharging stops, and as the next protrusion 6 arrives, the discharging continues. In this process, the electromagnet 442 corresponding to the horizontal section of the conveyor belt 41 works, and the magnetic pole strength changes continuously, driving the magnetic plate 423 to shake slightly, so that the tea leaves are shaken evenly on the paving board 421. When all the paving boards 421 are loaded with tea leaves, the single loading is completed, and the brake component is started to lock the roller 331. The conveyor belt 41 continues to move, driving the tea leaves in the outer shell 21 to be irradiated by the simulated fluorescent lamp 223 for withering. The corresponding electromagnets 442 at both ends of the conveyor belt 41 do not work, and the spreading plate 421 is transported to the transmission roller position following the conveyor belt 41 and remains in a horizontal state. The mounting hole 5 here is open, and the ventilation component 23 discharges the humid hot air from the mounting hole 5. After completing a period of withering, the electromagnet 442 corresponding to the horizontal section of the conveyor belt 41 works, driving the magnetic plate 423 to shake greatly, turning over the tea leaves on the spreading plate 421, and then withering for a period of time. After the withering is completed, the electromagnet 442 corresponding to the conveyor belt 41 outside the outer shell 21 works, causing the spreading plate 421 to tilt, and the tea leaves fall to complete the discharge.

[0026] Various modifications to these embodiments will be apparent to those skilled in the art. The general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will be accorded the widest scope consistent with the principles and novel features disclosed herein.
