Description

Technical Field

[0001] This utility model belongs to the field of black tea processing technology, specifically relating to a black tea pressing and forming machine. Background Technology

[0002] Black tea, a fully fermented tea, is the second largest tea category in China. It gets its name from the red color of its brewed tea liquor and leaves. The world's first black tea, named "Lapsang Souchong," was invented by tea farmers in the Wuyi Mountains of Fujian Province during the Ming Dynasty. It is made from the buds and leaves of the tea plant, refined through typical processes such as withering, rolling, fermentation, and drying. During fermentation, the chemical reactions involving tea polyphenols in black tea are reduced by more than 90%, and new components such as theaflavins and thearubigins are produced. Black tea is divided into three types: Gongfu black tea, Lapsang Souchong, and broken black tea.

[0003] Traditional tea cake presses rely on manual rotation of gears, resulting in relatively long pressing times per cycle. Demolding requires disassembling the sleeve. While hydraulic presses offer controllable pressure, loading and unloading cannot be done simultaneously with pressing, limiting production capacity. Furthermore, existing equipment lacks a softening process, making tea fibers prone to breakage and resulting in loose tea cakes. Alternatively, external steaming can be used for softening, but heat loss during the transfer process leads to an imbalance in moisture content control. Traditional cloth bag steaming can easily leave tea residue that breeds mold. Utility Model Content

[0004] The purpose of this invention is to provide a black tea pressing and forming machine, which aims to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A black tea pressing and forming machine includes: a pressing mechanism, a support frame fixedly connected to the rear of the pressing mechanism, and a feeding mechanism fixedly connected to the support frame;

[0007] The pressing mechanism includes a pressing table, a pressing frame fixedly connected above the pressing table, a first electric cylinder for longitudinal adjustment fixedly connected to the top of the pressing frame, an upper pressure plate fixedly connected to the piston rod of the first electric cylinder, a steam box fixedly connected to the upper surface of the pressing table and below the pressing frame, two guide plates fixedly connected to the rear side of the steam box, a lower template adapted to the steam box slidably connected to the inner side of the guide plates, a connecting seat fixedly connected to the upper surface of the guide plates, and a transfer hopper slidably connected to the upper surface of the connecting seat; a transfer box fixedly connected to the rear side of the bottom surface of the pressing frame, and the transfer hopper is adapted to the discharge port of the transfer box, and a conveying auger is rotatably connected inside the transfer box.

[0008] Compared with the prior art, the beneficial effects of this utility model are:

[0009] This solution involves feeding the tea leaves into the storage box via the feeding hopper of the feeding mechanism, then conveying them to the transfer box via the conveying pipe. The conveying auger pushes the tea leaves to the transfer hopper. At this time, the lower mold slides along the guide plate into the steam box. The steam box releases high-temperature steam to soften the tea leaves and improve their plasticity. Subsequently, the transfer hopper moves the softened tea leaves to the pressing station. The first electric cylinder drives the upper pressure plate to press down, which works with the lower mold to complete the shaping of the tea cake. Attached Figure Description

Detailed Implementation

[0017] 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.

[0018] Example

[0019] Please see Figure 1-4 The technical solution provided in this embodiment is as follows:

[0020] A black tea pressing and forming machine includes: a pressing mechanism 1, a support frame 2 fixedly connected to the rear of the pressing mechanism 1, and a feeding mechanism 3 fixedly connected to the support frame 2;

[0021] The pressing mechanism 1 includes a pressing table 101, a pressing frame 102 fixedly connected above the pressing table 101, a first electric cylinder 103 for longitudinal adjustment fixedly connected to the top of the pressing frame 102, an upper pressure plate fixedly connected to the piston rod of the first electric cylinder 103, a steam box 104 fixedly connected to the upper surface of the pressing table 101 and below the pressing frame 102, two guide plates 105 fixedly connected to the rear side of the steam box 104, a lower template 106 adapted to the steam box 104 slidably connected to the inner side of the guide plates 105, a connecting seat 107 fixedly connected to the upper surface of the guide plates 105, and a transfer hopper 108 slidably connected to the upper surface of the connecting seat 107; a transfer box 111 fixedly connected to the rear side of the bottom surface of the pressing frame 102, and the transfer hopper 108 is adapted to the discharge port of the transfer box 111, and a conveying auger 112 is rotatably connected inside the transfer box 111.

[0022] The tea leaves enter the storage box 302 through the feeding hopper 303 of the feeding mechanism 3, and are transported to the transfer box 111 through the conveying pipe 304. The conveying auger 112 pushes the tea leaves to the transfer hopper 108. At this time, the lower mold plate 106 slides along the guide plate 105 into the steam box 104. The steam box 104 releases high-temperature steam to soften the tea leaves and improve their plasticity. Then the transfer hopper 108 moves the softened tea leaves to the pressing station. The first electric cylinder 103 drives the upper pressure plate to press down, which works with the lower mold plate 106 to complete the shaping of the tea cake.

[0023] Specifically, a second electric cylinder 109 for horizontal adjustment is fixedly connected to the upper surface of the pressing table 101, and the piston rod of the second electric cylinder 109 is fixedly connected to the lower template 106.

[0024] In a specific embodiment of this utility model, the second electric cylinder 109 is rigidly connected to the lower template 106 through a piston rod, and horizontally pushes the lower template 106 to slide along the guide plate 105 to achieve switching. The sliding fit of the guide plate 105 eliminates displacement deviation and ensures that the lower template 106 is aligned with the center of the upper pressure plate, thus avoiding tea cake eccentricity or uneven thickness.

[0025] Specifically, a third electric cylinder 110 for horizontal adjustment is fixedly connected to the bottom of the transfer box 111, and the piston rod of the third electric cylinder 110 is fixedly connected to the transfer hopper 108.

[0026] In a specific embodiment of this utility model, the piston rod of the third electric cylinder 110 is fixed to the transfer hopper 108, and the transfer hopper 108 is pushed horizontally to slide on the connecting seat 107, so as to transfer the tea leaves from the discharge port of the transfer box 111 to the lower template 106.

[0027] Specifically, a servo motor 113 is fixedly connected to the surface of the transfer box 111, and the output shaft of the servo motor 113 is fixedly connected to the conveying auger 112.

[0028] In a specific embodiment of this utility model, the servo motor 113 drives the conveying auger 112 to rotate through the output shaft, so as to evenly push the tea leaves in the storage box 302 to the discharge port of the transfer box 111.

[0029] Specifically, the feeding mechanism 3 includes a feeding rack 301 fixedly connected to the upper surface of the support frame 2, a storage box 302 fixedly connected to the surface of the feeding rack 301, a feeding hopper 303 fixedly connected to the top of the storage box 302, and a conveying pipe 304 adapted to the transfer box 111 fixedly connected to the bottom of the storage box 302.

[0030] In a specific embodiment of this utility model, the feeding rack 301 supports the storage box 302 and the feeding hopper 303, and the tea leaves fall into the transfer box 111 by gravity through the conveying pipe 304.

[0031] Specifically, both sides of the bottom of the storage box 302 are rotatably connected to folding plates 305, and the surface of the folding plates 305 is rotatably connected to a connecting plate 306. One end of the inner side of the connecting plate 306 is fixedly connected to an opening and closing plate 307, and the two folding plates 305 are connected by a double-headed cylinder 308.

[0032] In a specific embodiment of this utility model, the double-headed cylinder 308 synchronously pushes two folded plates 305 to rotate around the axis, and the opening and closing angle is controlled by the connecting plate 306 to realize the opening and closing of the material conveying pipe 304.

[0033] Working principle: Loose tea enters the storage box 302 through the feeding hopper 303. The folding plate 305 opens periodically under the control of the double-headed cylinder 308. The tea leaves fall into the transfer box 111 through the conveying pipe 304. The servo motor 113 drives the conveying auger 112 to rotate, pushing the tea leaves to the discharge port of the transfer box 111 and into the transfer hopper 108. The transfer hopper 108 is moved above the steam box 104 by the third electric cylinder 110. At the same time, the second electric cylinder 109 pushes the lower template 106 to the steam station. The steam box 104 generates high-temperature steam that penetrates the tea leaf layer, softening it. After softening, the third electric cylinder 110 pulls the transfer hopper 108 to reset. At the same time, the lower template 106 catches the tea leaves. The first electric cylinder 103 drives the upper pressure plate to press down. After the pressure holding is completed, the upper pressure plate returns. The second electric cylinder 109 removes the lower template 106 from the steam box 104. At this time, the tea cake will fall.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
