Description

Technical Field

[0001] This utility model relates to the field of tea processing technology, specifically a withering device for fresh tea leaves. Background Technology

[0002] The leaf withering machine is a key piece of equipment used in the withering stage of tea making. It is mainly used to reduce the moisture content of fresh leaves and promote the transformation of internal substances, laying the foundation for subsequent processes.

[0003] In the prior art, patent announcement number CN222722367U discloses a tea withering machine, including a trough and a mesh plate installed in the trough. A main pipe extending along its axis is installed in the trough, and multiple branch pipes are connected to the main pipe. The multiple branch pipes are arranged at intervals along the axis of the trough. Multiple air outlets facing the mesh plate are also evenly opened on the branch pipes. A blower is provided on one side of the trough, and the air outlet pipe of the blower is connected to the main pipe. An electric heating wire is also installed in the air outlet pipe of the blower.

[0004] During use, the tea leaves are laid flat on a mesh tray, and hot air vents through the air holes to reduce the moisture content of the fresh leaves. When the hot air begins to circulate, the tea leaves at the bottom of the tray come into contact with the hot air first. Because some of the heat is absorbed by the bottom tea leaves, as the hot air continues to rise and reaches the upper tea leaves, the temperature of the air has decreased, which may result in the upper tea leaves drying less evenly than the bottom tea leaves. Utility Model Content

[0005] The purpose of this invention is to provide a withering device for fresh tea leaves to solve the problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a withering device for fresh tea leaves, comprising a device housing, an air inlet fixedly installed at one end of the device housing, a mesh plate fixedly installed at the upper edge of the device housing, a drive mechanism installed on the device housing, the drive mechanism comprising a motor fixedly installed inside the device housing and a mounting frame fixedly installed on the device housing, a reciprocating lead screw rotatably installed on the mounting frame, a lead screw nut installed on the reciprocating lead screw, a material turning mechanism connected to the lead screw nut, and a slide rail mechanism installed on one side of the device housing.

[0007] Preferably, the drive mechanism further includes a transmission shaft rotatably mounted between the reciprocating screw and the motor, wherein helical gears are fixedly mounted at one end of the reciprocating screw, both ends of the transmission shaft, and the output end of the motor, and the helical gears mesh together in pairs, and fan blades are fixedly mounted at the output end of the motor.

[0008] Preferably, the mounting bracket is equipped with a bearing, and the reciprocating lead screw is rotatably mounted on the mounting bracket via the bearing.

[0009] Preferably, the fan blades are mounted inside the air inlet by a motor, and the lead screw nut is mounted above the mesh plate by a reciprocating lead screw.

[0010] Preferably, the material turning mechanism includes a base slidably mounted on the upper end of the equipment housing, and the base is fixedly mounted on a lead screw nut. A sliding strip is slidably mounted inside the base. Rake teeth are fixedly mounted at the bottom of the sliding strip. Sliding feet are fixedly mounted at both ends of the sliding strip. A positioning seat is fixedly mounted inside the base. A return spring is provided between the positioning seat and the sliding feet. A top rod is fixedly mounted on the sliding feet.

[0011] Preferably, the slide rail mechanism includes a slide rail seat fixedly installed on one side of the equipment housing, a slide rail body slidably installed inside the slide rail seat, a connecting plate fixedly installed on the slide rail body, an electric push rod fixedly installed on one side of the slide rail seat, and the output end of the electric push rod fixedly installed on the connecting plate.

[0012] Preferably, the rake teeth are slidably mounted on the bottom of the base via a sliding strip, one end of the reset spring is connected to the positioning seat, and the other end of the reset spring is connected to the sliding support.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In this application, after the motor starts, it drives the fan blades and drive shaft to rotate. The rotation of the fan blades acts on the airflow, blowing it towards the tea leaves. The rotation of the drive shaft further drives the reciprocating lead screw to rotate, and the rotation of the reciprocating lead screw causes the lead screw nut to reciprocate linearly. During the reciprocating linear motion of the lead screw nut, the rake teeth at the bottom of the base reciprocate back and forth, thereby turning the tea leaves on the screen back and forth to achieve the effect of uniform withering of the tea leaves.

[0015] In this application, during the back-and-forth movement of the base, the sliding of the top rod along the slide rail body causes it to move left and right. This left-and-right movement of the top rod then drives the sliding bar to move laterally, which in turn causes the rake teeth to perform a left-and-right oscillating motion. This action allows the tea leaves on the screen to be turned left and right. Simultaneously, through the action of the electric push rod, the connecting plate moves forward. The forward movement of the connecting plate causes the slide rail body to move forward, thereby changing the left-and-right trajectory of the top rod. This alters the trajectory of the rake teeth as they turn the tea leaves, thus achieving uniform heating of the tea leaves. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1 and Figure 2 As shown, this utility model provides a technical solution for a withering device for fresh tea leaves, including a device housing 1, an air inlet 2 fixedly installed at one end of the device housing 1, a mesh plate 3 fixedly installed at the upper edge of the device housing 1, a drive mechanism 4 installed on the device housing 1, a turning mechanism 5 connected to a lead screw nut 406, and a slide rail mechanism 6 installed on one side of the device housing 1. Through the coordinated use of the drive mechanism 4, the turning mechanism 5 and the slide rail mechanism 6, the tea leaves on the mesh plate 3 can be turned over, so that the tea leaves wither evenly.

[0023] like Figure 2 and Figure 3As shown, the drive mechanism 4 includes a motor 401 fixedly installed inside the equipment housing 1 and a mounting bracket 405 fixedly installed on the equipment housing 1. A reciprocating lead screw 407 is rotatably installed on the mounting bracket 405, and a lead screw nut 406 is installed on the reciprocating lead screw 407. The drive mechanism 4 also includes a transmission shaft 403 rotatably installed between the reciprocating lead screw 407 and the motor 401. Helical gears 404 are fixedly installed at one end of the reciprocating lead screw 407, both ends of the transmission shaft 403, and the output end of the motor 401. The helical gears 404 mesh together in pairs. A fan blade 402 is fixedly installed at the output end of the motor 401. A bearing is installed on the mounting bracket 405, and the reciprocating lead screw 407 is rotatably installed on the mounting bracket 405 through the bearing.

[0024] Specifically, when motor 401 is started, it drives fan blades 402 and drive shaft 403 to rotate. During rotation, fan blades 402 generate airflow and blow it onto the tea leaves, aiding in drying. Simultaneously, the rotating drive shaft 403 further drives the reciprocating screw 407 to rotate. The rotation of the reciprocating screw 407 causes the screw nut 406 to reciprocate back and forth. This reciprocating motion of the screw nut 406, in turn, drives the rake teeth 503 at the bottom of the base 501 to reciprocate accordingly. This movement of the rake teeth 503 causes the tea leaves on the mesh plate 3 to be turned over, achieving a uniform withering effect.

[0025] like Figure 3 and Figure 4 As shown, the material turning mechanism 5 includes a base 501 slidably installed on the upper end of the equipment housing 1, and the base 501 is fixedly installed on the lead screw nut 406. A sliding strip 502 is slidably installed inside the base 501. A rake tooth 503 is fixedly installed at the bottom of the sliding strip 502. Sliding support feet 506 are fixedly installed at both ends of the sliding strip 502. A positioning seat 504 is fixedly installed inside the base 501. A return spring 505 is provided between the positioning seat 504 and the sliding support foot 506. A top rod 507 is fixedly installed on the sliding support foot 506. The slide rail mechanism 6 includes a slide rail seat 601 fixedly installed on one side of the equipment housing 1. A slide rail body 602 is slidably installed inside the slide rail seat 601. A connecting plate 603 is fixedly installed on the slide rail body 602. An electric push rod 604 is fixedly installed on one side of the slide rail seat 601, and the output end of the electric push rod 604 is fixedly installed on the connecting plate 603.

[0026] Specifically, when the base 501 moves back and forth, the push rod 507 slides along the slide rail body 602. During this process, the push rod 507 not only slides back and forth along the slide rail body 602 but also moves left and right. This left and right movement of the push rod 507 causes the sliding bar 502 to also move left and right accordingly. The left and right movement of the sliding bar 502, in turn, drives the rake teeth 503 to move left and right. The left and right movement of the rake teeth 503 is responsible for turning the tea leaves on the mesh plate 3 left and right, ensuring that the tea leaves are turned evenly. Furthermore, the electric push rod 604 can push the connecting plate 603 forward. After the connecting plate 603 moves forward, it further drives the slide rail body 602 forward, thereby adjusting the trajectory of the push rod 507's left and right movement, causing the trajectory of the rake teeth 503 to turn the tea leaves each time. In this way, it is further ensured that the tea leaves are heated evenly, thereby improving the quality and efficiency of tea processing.

[0027] Working principle: When using, first spread the tea leaves flat on the mesh plate 3. After the tea leaves are spread flat on the mesh plate 3, start the motor 401. After starting the motor 401, it will drive the fan blades 402 and the transmission shaft 403 to rotate. After the fan blades 402 rotate, the airflow will blow towards the tea leaves. After the transmission shaft 403 rotates, it will drive the reciprocating screw 407 to rotate. After the reciprocating screw 407 rotates, it will drive the screw nut 406 to move back and forth. During the back and forth movement of the screw nut 406, it will drive the rake teeth 503 at the bottom of the base 501 to move back and forth, turning the tea leaves on the mesh plate 3 back and forth, so that the tea leaves wither evenly. Furthermore, when the base 501 moves back and forth, the top rod 507 slides along the slide rail body 602. As the top rod 507 slides along the slide rail body 602, it also moves left and right. This left and right movement of the top rod 507 causes the sliding bar 502 to move left and right, which in turn causes the rake teeth 503 to move left and right, flipping the tea leaves on the mesh plate 3. The electric push rod 604 can also drive the connecting plate 603 forward. After the connecting plate 603 moves forward, it causes the slide rail body 602 to move forward a certain distance, thereby adjusting the left and right trajectory of the top rod 507. This changes the trajectory of the rake teeth 503 each time they flip the tea leaves, further ensuring that the tea leaves are heated evenly.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
