Description

Technical Field

[0001] This utility model relates to the technical field of tea processing equipment, and in particular to a quantitative feeding device for tea packaging. Background Technology

[0002] Tea is classified into six categories according to its processing methods, including green tea, white tea, and black tea. Tea can be used as a beverage, contains many beneficial components, and has health benefits. Tea packaging has become an important part of China's tea industry. During the packaging process, tea needs to be weighed before being placed into packaging boxes.

[0003] However, in the current tea packaging process, the tea is usually weighed manually before being dispensed. This manual weighing is not only inefficient but also inaccurate. In addition, some broken tea leaves may contain dust during the dispensing process, and this dust can easily combine with moisture in the air, causing the tea leaves to stick together and resulting in damage to the quality of the tea products dispensed later.

The placement blocks 2 are evenly distributed on the conveyor belt 1. The conveying speed of the conveyor belt 1 is consistent with the material dropping speed, that is, when the material is dropped into the material dropping groove 10, the tea leaves can fall into the evenly distributed placement blocks 2 on the conveyor belt 1. The upper middle part of the frame is provided with a mounting plate 3; the material dropping box 4 is provided on the mounting plate 3; the cleaning mechanism 5 is provided inside the material dropping box 4; the bottom of the material dropping box 4 is connected to the discharge box 6; the discharge box 6 is provided with a guide block 7; the material dropping cylinder 8 is rotatably installed at the bottom of the discharge box 6; the rear end of the mounting plate 3 is provided with a first drive motor 9; the output end of the first drive motor 9 is connected to the material dropping cylinder 8; the material dropping groove 10 is provided inside the material dropping cylinder 8; the discharge port 11 is provided at the bottom of the discharge box 6.

[0027] The side wall of the feeding box 4 is provided with the exhaust fan 51; the inside of the feeding box 4 is provided with the exhaust pipe 52 communicating with the exhaust fan 51; a plurality of exhaust ports 53 are evenly distributed on the exhaust pipe 52; a heating resistance wire is provided inside the exhaust pipe 52; the side wall of the feeding box 4 is also provided with a suction box; during the process of extracting debris, due to the negative pressure setting, most of the debris is extracted by the suction fan inside the suction box, and the blower is located at the bottom of the feeding box 4 to further prevent dust and debris from entering the discharge box 6; the top of the feeding box 4 is hinged with the flip cover 54; the rotating rod 55 is rotatably installed inside the feeding box 4; the side wall of the feeding box 4 is also provided with the second drive motor 56; the output end of the second drive motor 56 is connected to the rotating rod 55; the end face of the rotating rod 55 is fixedly connected with the screening frame 57; the screening frame 57 is provided with the feeding assembly 58.

[0028] The feeding assembly 58 includes a gap 581, a sliding plate 582, a slide bar 583, a support rod 584, a third drive motor 585, a gear 586, and a rack 583;

[0029] The screening frame 57 has a plurality of gaps 581 evenly distributed thereon, and a sliding plate 582 is slidably mounted on one of the gaps 581; the sliding plate 582 is provided with a sliding strip 583; the remaining gaps 581 may be equipped with mesh bags; a support rod 584 is fixedly provided on the top of the screening frame 57; a mounting plate is provided on the support rod 584; the third drive motor 585 is provided on the mounting plate; the output end of the third drive motor 585 is connected to the gear 586; the gear 586 meshes with the rack 583.

[0030] Working principle: First, the tea leaves are fed into the feeding box 4. Then, the second drive motor 56 is turned on, so that the output end of the motor drives the rotating rod 55 to rotate. Then, the screening frame 57 is driven. The rotation of the screening frame 57 causes the tea leaves to roll in the inner cavity of the screening frame 57, so that the dust and tea leaves collide and separate.

[0031] By turning on the exhaust fan 51, air is sprayed out from the exhaust port 53 at the upper end of the exhaust pipe 52. The fan inside the exhaust pipe 52 rotates, thereby drying the tea leaves and removing dust. This makes it easier for the tea leaves to separate more quickly during the rolling process. The dust is then collected by the suction fan.

[0032] After cleaning, the tea leaves fall into the discharge box 6. The first drive motor 9 is activated, causing the feeding cylinder 8 to rotate, quantitatively discharging the tea leaves into each feeding groove 10. The tea leaves then exit through the discharge port 11 at the bottom of the discharge box 6, falling into the placement block 2 above the conveyor belt 1. Before the placement block 2 is conveyed, the worker places a packaging bag onto it. The drive cylinder is then activated, causing the pressure plate to flatten the tea leaves inside the packaging bag, facilitating subsequent packaging. Content not described in detail in this specification is prior art known to those skilled in the art.

[0033] The embodiments described above are merely preferred embodiments of the present invention, and are described in a relatively specific and detailed manner. However, the present invention is not limited to these embodiments. It should be noted that for those skilled in the art, any improvements made without departing from the spirit of the present invention fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
