A tea impurity removal device

Abstract

This invention relates to the field of tea processing technology and discloses a tea impurity removal device, including a combing machine and an infrared color sorter. The combing machine has a tea refining machine at its feeding end, a translating machine at its feeding end, and an elevator at its feeding end to lift the tea leaves into the infrared color sorter. The device also includes an electrical control box. This invention removes impurities from the tea leaves before they are fed into the infrared color sorter, thereby reducing the pressure on the color sorter and effectively improving tea quality. The electrical control box controls the coordinated operation of the equipment. Furthermore, the feeding end of the combing machine can blow away ash from the falling tea leaves. Simultaneously, a driving component drives a striking cam to rotate, which reciprocates by striking a shaking mechanism, causing the shaking mechanism to rise and fall repeatedly, thus dispersing the falling tea leaves and ensuring that the gas ejected from the vent effectively blows away ash from the falling tea leaves.

Technical Field

[0001] This invention relates to the field of tea processing technology, and in particular to a tea impurity removal device. Background Technology

[0002] During the tea picking process, tea leaves often become contaminated with impurities such as tea fruit, tea buds, and dust. For health and food safety reasons, it is necessary to remove these impurities, especially harmful ones. With the widespread research, development, and use of color sorters in my country, many large and medium-sized tea companies now use tea color sorters for impurity removal. This improves the efficiency and automation of tea impurity removal, reduces manual labor, and to a certain extent ensures the stability of impurity sorting and removal results.

[0003] If impurities such as tea leaves, dust, stones, and hair can be removed before they enter the color sorting equipment, reducing the pressure on the color sorter, the quality of the tea can be effectively improved. Currently, the combing machine in tea impurity removal equipment does not have the technical effect of effectively shaking and removing dust from the tea leaves after initial dispersion. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a tea impurity removal device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A tea impurity removal device includes a combing machine and an infrared color sorter. The combing machine has a tea refining machine at its feeding end, a translating machine at its feeding end, and an elevator at its feeding end for lifting the tea leaves into the infrared color sorter. The device also includes an electrical control box for controlling the equipment. The combing machine's feeding end has a feeding housing for transferring the dispersed tea leaves into the tea refining machine. The combing machine's feeding end also has a fan, and the fan's outlet has an air guide hood extending into the feeding housing. One end of the combing machine is provided with an air outlet housing, and the side wall of the air outlet housing is provided with an air outlet hole; the feeding end of the combing machine is provided with a dust collection housing, which is used to collect impurities blown by the air outlet housing; the inside of the feeding housing is provided with a shaking mechanism, which is used to shake the tea leaves falling at the feeding housing; the position of the shaking mechanism corresponds to the opening position of the air outlet hole; a striking cam is movably installed on the inner wall of the feeding housing, and a driving component is also included for driving the striking cam to rotate, the position of the striking cam corresponds to the position of the shaking mechanism.

[0007] Preferably, the material shaking mechanism includes several fixed seats horizontally installed inside the material feeding housing, and inclined material shaking side wings are installed on both sides of the fixed seats by means of springs.

[0008] Preferably, mounting seats are slidably installed on both inner walls of the feeding housing, and the same lifting seat is installed on the opposite side of the two mounting seats at the same horizontal position. The lifting seat is located on top of the adjacent fixed seat, and the top side of the material shaking wing is movably connected to the side of the lifting seat.

[0009] Preferably, the fixing base has a through first hole at both ends and a through second hole at the top, with the opening positions of the first and second holes corresponding to each other.

[0010] Preferably, a lifting rod is movably installed inside the first and second perforations, and a pushing component is provided on the side of the lifting rod, which is located between the lifting seat and the fixed seat; the bottom position of the lifting rod corresponds to the position of the striking cam.

[0011] Preferably, the inner wall of the unloading housing is provided with a guide groove, and a guide block is provided on the side of the mounting seat away from the lifting seat. The outer diameter of the guide block is adapted to the inner diameter of the guide groove, which is used to guide the lifting and lowering movement of the mounting seat and the lifting seat.

[0012] Preferably, the length of the material-shaking side wings increases sequentially from top to bottom.

[0013] The beneficial effects of this invention are as follows:

[0014] In operation, the tea leaves to be processed are fed into the combing machine, which initially disperses the tea leaves. The processing speed can be controlled by the rotation speed of the belt inside the combing machine. The refining machine further shakes and removes impurities from the tea leaves after initial dispersion. A transfer machine then transports the tea leaves, after impurity removal by the refining machine, to an elevator. The elevator then lifts the tea leaves and feeds them into an infrared color sorter. The infrared color sorter separates the tea leaves from discolored impurities, harmful impurities, stems, buds, and leaves, in addition to the tea leaves themselves. This meets customer needs by removing impurities from the tea leaves before they are fed into the infrared color sorter, thereby reducing color defects. The pressure of the machine selection can effectively improve the quality of tea. The coordinated operation of the equipment can be controlled by the electrical control box. At the feeding end of the combing machine, air can be injected into the air outlet housing through the fan and air guide hood. The airflow is sprayed out from the air outlet to blow dust off the tea leaves falling from the feeding end of the combing machine. The light dust blown away from the tea leaves falls into the dust collection housing. At the same time, the drive component drives the striking cam to rotate. The striking cam reciprocates to strike the shaking mechanism, causing the shaking mechanism to rise and fall and shake back and forth, thereby shaking and dispersing the tea leaves falling from the feeding end of the combing machine, ensuring that the air sprayed from the air outlet can effectively blow dust off the falling tea leaves.

A tea refining machine 2 is installed at the feeding end of the combing machine 1. A translation machine 3 is installed at the feeding end of the tea refining machine 2. A lifting machine 4 is installed at the feeding end of the translation machine 3 to lift the tea leaves into the infrared color sorter 5. The device also includes an electrical control box 6 for controlling the equipment. A feeding shell 9 is installed at the feeding end of the combing machine 1 to transfer the dispersed tea leaves into the tea refining machine 2. A fan 7 is installed at the feeding end of the combing machine 1, and an air guide hood 8 is installed at the air outlet end of the fan 7, extending into one end of the feeding shell 9. The machine is equipped with an air outlet housing 12, and the side wall of the air outlet housing 12 has an air outlet hole; the feeding end of the combing machine 1 is equipped with a dust collection housing 11, which is used to collect impurities blown by the air outlet housing 12; the inside of the feeding housing 9 is equipped with a shaking mechanism 24, which is used to shake the tea leaves falling at the feeding housing 9; the position of the shaking mechanism 24 corresponds to the opening position of the air outlet hole; the inner wall of the feeding housing 9 is movably installed with a striking cam 13, and also includes a driving component 21 for driving the striking cam 13 to rotate, the position of the striking cam 13 corresponds to the position of the shaking mechanism 24.

[0027] In operation, the tea leaves to be processed are fed into the combing machine 1, which initially disperses the tea leaves. The processing speed can be controlled by the rotation speed of the belt inside the combing machine 1. The refining machine 2 further shakes and removes impurities from the tea leaves initially dispersed by the combing machine 1. The transfer machine 3 conveys the tea leaves after impurity removal by the refining machine 2 to the elevator 4. The elevator 4 lifts the tea leaves and feeds them into the infrared color sorter 5. The infrared color sorter 5 separates the discolored impurities, harmful impurities, stems, buds, and leaves from the tea leaves to meet customer needs. The coordination of the equipment can be controlled by the electrical control box 6. When the combing machine 1 is in operation, air can be injected into the air outlet housing 12 through the fan 7 and the air guide 8 at the feeding end. The airflow is sprayed out from the air outlet to blow dust off the tea leaves falling from the feeding end of the combing machine 1. The light dust blown off the tea leaves falls into the dust collection housing 11. At the same time, the drive component 21 drives the striking cam 13 to rotate. The striking cam 13 repeatedly strikes the shaking mechanism 24, causing the shaking mechanism 24 to rise and fall repeatedly and shake, thereby shaking and dispersing the tea leaves falling from the feeding end of the combing machine 1, ensuring that the air sprayed from the air outlet can effectively blow dust off the falling tea leaves.

[0028] In a preferred embodiment of the present invention, the driving component 21 is a DC motor.

[0029] As a preferred embodiment of the present invention, the material shaking mechanism 24 includes a plurality of fixed seats 18 horizontally installed inside the material feeding housing 9, and inclined material shaking side wings 10 are installed on both sides of the fixed seats 18 by means of springs 15.

[0030] In a preferred embodiment of the present invention, mounting seats 19 are slidably installed on both inner walls of the feeding housing 9. The same lifting seat 14 is installed on the opposite side of the two mounting seats 19 at the same horizontal position. The lifting seat 14 is located on the top of the adjacent fixed seat 18. The top side of the shaking side wing 10 is movably connected to the side of the lifting seat 14.

[0031] In a preferred embodiment of the present invention, the fixed base 18 has a through first hole 22 at both ends, and the mounting base 19 has a through second hole 23 at the top. The opening positions of the first hole 22 and the second hole 23 correspond to each other.

[0032] In a preferred embodiment of the present invention, a lifting rod 17 is movably disposed inside the first through hole 22 and the second through hole 23, and a pushing component 16 is disposed on the side of the lifting rod 17. The pushing component 16 is located between the lifting seat 14 and the fixed seat 18; the bottom position of the lifting rod 17 corresponds to the position of the striking cam 13.

[0033] In a preferred embodiment of the present invention, a guide groove 20 is provided on the inner wall of the feeding housing 9, and a guide block is provided on the side of the mounting base 19 away from the lifting seat 14. The outer diameter of the guide block is adapted to the inner diameter of the guide groove 20, which is used to guide the lifting and lowering movement of the mounting base 19 and the lifting seat 14. When the tea leaves fall at the feeding end of the combing machine 1, the driving component 21 drives the striking cam 13 to rotate. The striking cam 13 repeatedly strikes the bottom of the lifting rod 17. Under the striking action of the striking cam 13, the lifting rod 17 moves upward. At this time, the pushing component 16 pushes upward with the upward movement of the lifting rod 17. The lifting seat 14 is moved, and the shaking side wing 10 is moved upward under the pulling action of the lifting seat 14. The side of the shaking side wing 10 is compressed and installed with spring 15. When the striking cam 13 is misaligned with the bottom end of the lifting rod 17, the lifting rod 17, the lifting seat 14, and the shaking side wing 10 move downward under the action of gravity. At this time, the shaking side wing 10 is reset and unfolded under the elastic action of the installed spring 15. That is, the lifting seat 14 moves up and down and shakes back and forth, while the shaking side wing 10 swings back and forth, so that when the tea leaves come into contact with the shaking side wing 10 and the lifting seat 14, they can be effectively shaken apart, improving the dust blowing effect of the air outlet housing 12.

[0034] In a preferred embodiment of the present invention, the length of the shaking side wing 10 increases sequentially from top to bottom, ensuring that the shaking side wing 10 at the bottom can contact the tea leaves that have been shaken and dispersed by the shaking side wing 10 at the top, and to shake and disperse the tea leaves multiple times.

[0035] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
