Description

Technical Field

[0001] This utility model relates to the field of tea processing technology, and in particular to a tea withering machine that provides uniform heating. Background Technology

[0002] Tea leaves, commonly known as tea, generally include the leaves and buds of the tea plant. Other names include tea, jia, ming, and chuan. Tea contains catechins, cholesterol, caffeine, inositol, folic acid, and pantothenic acid, all beneficial to health. Tea beverages are one of the world's three major beverages. The processing steps for tea are: withering, cooling, oxidation, pan-frying, rolling, roasting, and finally, evenly stacking and packaging.

[0003] With economic development, tea leaves are withered using a tea withering trough cooling machine. For example, utility model CN220675047U discloses a tea withering machine, including a base, a tea withering machine body fixedly installed on top of the base, and a control panel fixedly installed outside the tea withering machine body. A withering trough frame is fixedly installed on the top of the tea withering machine body, and a filter screen is fixedly installed on the inner bottom wall of the withering trough frame. The tea withering machine body has a collection rack and a mounting plate inside. By operating the control panel, the first telescopic cylinder is activated, causing its output end to lift one side of the collection rack. At this time, the collection rack is tilted, facilitating the unloading of tea leaves from the collection rack, improving tea cleaning efficiency, and achieving advantages such as easy collection. This solves the problem of workers finding it inconvenient to collect tea leaves from the collection plate.

[0004] However, the withering machine in the above application requires manual spreading of tea leaves in the withering trough and manual picking up of withered tea leaves, which affects the uniformity of heating and discharge efficiency of the tea leaves during the withering process, thus affecting the processing efficiency. Therefore, a tea withering machine with uniform heating is proposed. Utility Model Content

For example, "connected" can be a fixed connection, such as welding, riveting, or bonding; it can also be a detachable connection, such as threaded connection, keyed connection, or pin connection; or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] like Figure 1-4 As shown, the present invention proposes a tea withering machine with uniform heating, including a frame 1, a discharge port 2 on the front of the frame 1, a tea withering processing component 4 on the frame 1, a tea placing trough 3 on the processing component 4, and a set of hot air fans 5 installed on the back of the frame 1.

[0026] In this invention, the processing component 4 located on the frame 1 can drive the placement trough 3 to vibrate while also driving the placement trough 3 to rotate, so that the tea leaves in the placement trough 3 can be automatically discharged, improving the convenience of material discharge.

[0027] In an optional embodiment, the processing component 4 includes two support plates 41 slidably connected to the inner wall of the frame 1. The placement slot 3 is rotatably connected between the two support plates 41. A horizontal plate 43 located below the placement slot 3 is fixedly connected between the two support plates 41. A guide frame 48 is slidably connected to the horizontal plate 43. A set of first racks 45 is fixedly installed on the guide frame 48, and one end of the first rack 45 passes through the frame 1. A set of second racks 47 is fixedly connected to the outer surface of the placement slot 3. A mounting frame 44 is fixedly connected to the back of the horizontal plate 43. A dual-axis motor 410 is fixedly installed on the inner side of the mounting frame 44. The output shaft of the dual-axis motor 410 is fixedly connected to gears 411 that mesh with the first rack 45 and the second rack 47 respectively. A drive motor 412 is fixedly installed on the back of the frame 1. A rotating shaft 49 with one end passing through and extending to the inner side of the frame 1 is fixedly connected to the output shaft of the drive motor 412. A set of cams 413 is fixedly connected to the outer side of the rotating shaft 49.

[0028] In this embodiment, when the cam 413 is driven to rotate by the start-up drive motor 412 and repeatedly vibrates the placement groove 3 on the support plate 41, the tea leaves can be automatically flattened to improve the heat uniformity of the tea leaves during withering. When the gear 411 is driven to rotate by the start-up dual-axis motor 410, it can cooperate with the first rack 45 and the second rack 47 to drive the guide frame 48 to slide outward from the discharge port 2, while also driving the placement groove 3 to rotate, so that the tea leaves in the placement groove 3 fall into the guide frame 48 for discharge, thereby improving the convenience for operators to collect the discharged tea leaves.

[0029] It should be noted that the inner wall of the frame 1 is provided with a groove for the support plate 41 to slide. The lower end of both the support plate 41 and the groove is T-shaped. Several springs 42 are fixedly connected between the T-shaped end of the support plate 41 and the inner side of the groove. The springs located between the groove and the support plate 41 provide elastic support to the support plate 41 to improve the buffering performance of the support plate 41 when it vibrates with the horizontal plate 43.

[0030] The placement trough 3 is semi-circular, and the front and rear sides of the inner wall of the placement trough 3 are inclined. The inner bottom wall of the placement trough 3 has a number of ventilation holes, so that the hot air blown by the hot air blower 5 can be blown through the ventilation holes onto the flat tea leaves.

[0031] In addition, two second racks 47 are symmetrically distributed in a fan shape on the placement groove 3, and the first racks 45 are symmetrically distributed in a straight line on the upper surface of the guide frame 48. The inner bottom wall of the guide frame 48 is inclined and one end is missing, so that the tea leaves falling into the guide frame 48 can slide along the inclined part and be discharged through the missing end of the guide frame 48.

[0032] Secondly, the mounting bracket 44 is U-shaped, and a rectangular groove is opened on the inner wall of the frame 1 for the mounting bracket 44 to slide, so that the mounting bracket 44 on the connecting frame horizontal plate 43 has space to move up and down. The upper end of the mounting bracket 44 is conical, and the left and right sides of the mounting bracket 44 are fixedly connected with support covers 46 located on the outside of the gear 411 and the second rack 47, respectively. When the tea leaves fall along the ventilation hole on the placement groove 3, the guide of the conical end of the mounting bracket 44 and the blocking of the support cover 46 can prevent the tea leaves from falling onto the gear 411 and affecting the rotation of the gear 411.

[0033] Then, a set of sliders is fixedly connected to the upper surface of the horizontal plate 43, and a groove for the sliders to slide on the lower surface of the guide frame 48 is provided to improve the stability of the guide frame 48 sliding on the slide plate.

[0034] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art, which is common knowledge in the field. Since this utility model is mainly used to protect mechanical structures, the control method and circuit connection and other technical means will not be described in detail here.

[0035] The working principle in the above embodiments is as follows:

[0036] After the tea leaves to be withered are placed in the placement trough 3, they can be automatically spread out without manual flattening. The drive motor 412 drives the cam 413 on the rotating shaft 49 to rotate, causing the cam 413 to repeatedly push up the support plate 41, thereby causing the placement trough 3 to vibrate. This automatically flattens the tea leaves. At the same time, during withering, the vibration between the tea leaves creates some gaps, which improves the uniformity of heating during withering. After the tea leaves have withered, the dual-shaft motor 410 drives the gear 411 to rotate, which in turn drives the first rack 45 to... While the guide frame 48 slides outward toward the discharge port 2, it can also drive the placement groove 3 to rotate through the second rack 47. When most of the volume of the guide frame 48 slides out of the discharge port 2, the placement groove 3 is rotated to an inclined position. With the vibration, the tea leaves in the placement groove 3 can fall along the inner side of the frame 1 into the guide frame 48, and then be discharged through the inclined part of the bottom wall of the guide frame 48. The operator only needs to place a regular receiving box to the missing end of the guide frame 48 to collect the tea leaves, thereby improving the convenience of the operator when collecting the tea leaves.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
