Description

Technical Field

[0001] This utility model relates to the technical field of tea rolling machines, specifically a tea rolling machine with steam function. Background Technology

[0002] Rolling is the shaping process in the initial processing of oolong tea. Rolling forms its tight and curved shape and also affects the improvement of its internal quality. Rolling can tighten the tea strips, reduce their volume, and lay a good foundation for drying into strips. It also appropriately breaks down the leaf tissue and promotes the transformation of substances. Oolong tea is mostly rolled using a rolling machine. There are various models of rolling machines. During the rolling process, the tea should be rinsed or turned once in the rolling drum. The rolling process should follow the principles of "hot rolling, appropriate pressure, speed, and short time".

[0003] There are still some problems with the existing tea rolling machines. During the rolling process, some tea leaves are relatively dry, and these leaves are more prone to breakage, affecting the integrity and appearance of the tea. At the same time, the tea aroma is more easily lost, resulting in a monotonous and bland aroma, which has a certain impact on the quality of subsequent tea production. Utility Model Content

[0004] The purpose of this invention is to provide a tea kneading machine with a steam function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a tea kneading machine with steam function, comprising a chassis, with supports installed on three sides of the lower end of the chassis, a transmission wheel connected to the outer end of one support, a rotating shaft vertically installed inside the other support, and the lower end of the rotating shaft being connected to the transmission wheel, a connecting arm connected to the upper end of the rotating shaft, the connecting arm being rotatably connected to the outer side of a connecting ring, a tea barrel being installed inside the connecting ring, a lifting and opening assembly being provided opposite to the outer side of the tea barrel, and the lifting and opening assembly being connected to the outer side of the connecting ring, a steam assembly being installed at the lower end of the chassis, and a baffle being installed at the bottom of the chassis, and the baffle being connected to the outside of the steam assembly.

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

[0014] 1. This utility model incorporates a lifting and opening assembly. Under the meshing transmission of the first and second bevel gears, the screw inside the guide cylinder can rotate, flexibly enabling the moving sleeve to move up and down. Guided by the first guide groove, the moving sleeve can move the rotating arm up and down, thereby driving the pressure plate to move up and down, thus pressing the tea leaves inside the tea canister.

Detailed Implementation

[0024] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0025] Please see Figure 1-2 This utility model provides a tea kneading machine with steam function, including a chassis 1, with supports 2 installed on three sides of the lower end of the chassis 1. The outer end of the front support 2 is connected to a transmission wheel 3, and the transmission wheel 3 is connected to an external drive device. A rotating shaft 4 is vertically installed inside the front support 2, and the lower end of the rotating shaft 4 is connected to the transmission wheel 3. A connecting arm 5 is connected to the upper end of the rotating shaft 4, and the connecting arm 5 is rotatably connected to the outer side of a connecting ring 6. A tea barrel 7 is installed inside the connecting ring 6, and there is a gap between the lower end of the tea barrel 7 and the chassis 1. A lifting and opening assembly 8 is provided opposite to the outer side of the tea barrel 7, and the lifting and opening assembly 8 is connected to the outer side of the connecting ring 6. A steam assembly 9 is installed at the lower end of the chassis 1, and a baffle 10 is installed at the bottom of the chassis 1, and the baffle 10 is connected to the outside of the steam assembly 9.

[0026] Among them, the connecting arm 5 is rotatably connected to the three sides of the outer end of the connecting ring 6, and the other two connecting arms 5 are rotatably connected to the upper ends of the two side supports 2, so as to ensure that the three connecting arms 5 are connected to the three sides of the outer end of the connecting ring 6, so as to ensure the stable realization of the subsequent bias kneading process.

[0027] Please see Figure 3-4 In this embodiment, the lifting and opening assembly 8 includes a connecting seat 81 installed on the upper front side of the connecting ring 6, a motor 82 connected to the side of the connecting seat 81, a first bevel gear 83 connected to the bottom output end of the motor 82, a second bevel gear 84 meshing with the side of the first bevel gear 83 and located inside the connecting seat 81, a screw 85 vertically connected to the upper end of the second bevel gear 84, a guide cylinder 86 installed on the outside of the screw 85 and connected to the upper end of the connecting seat 81, and the lifting and guiding engagement can be achieved through the installation of the guide cylinder 86, a movable sleeve 87 movably built into the guide cylinder 86 and threadedly connected to the screw 85, and a first bevel gear 84 opened on the front side of the guide cylinder 86. The guide groove 88 and the second guide groove 89, which are located at the upper front end of the guide cylinder 86 and connected to the upper end of the first guide groove 88, can achieve stable guidance during the lifting, rotating and opening / closing process through the guidance of the first guide groove 88. The rotating arm 810, which is movably sleeved on the outside of the guide cylinder 86 and connected to the outside of the movable sleeve 87, can drive the rotating arm 810 simultaneously when the movable sleeve 87 moves and rotates. The vertical rod 811, which is vertically connected to the side of the rotating arm 810 away from the guide cylinder 86, and the pressure plate 812, which is connected to the lower end of the vertical rod 811 and located inside the tea canister 7, can assist in the kneading and processing of tea leaves through the setting of the pressure plate 812.

[0028] The first guide groove 88 is vertically grooved along the front side of the guide cylinder 86, and its upper end is connected to the second guide groove 89, ensuring that the cooperation between the first guide groove 88 and the second guide groove 89 can achieve stable rotational opening and closing. The second guide groove 89 is semi-arc-shaped, and both the interior of the second guide groove 89 and the first guide groove 88 are connected to the front side of the movable sleeve 87, ensuring that when the movable sleeve 87 is screwed into the interior of the second guide groove 89, it can cooperate with the overall shape of the second guide groove 89 to achieve self-rotational transmission.

[0029] Please see Figure 5-7 In this embodiment, the steam assembly 9 includes fixed seats 91 that are symmetrically and fastened to both sides of the bottom of the chassis 1, connecting rods 92 that are rotatably connected to the inside of the fixed seats 91 on both sides, rocker arms 93 connected to one side of the connecting rods 92, opening and closing plates 94 connected to the outside of the connecting rods 92 and located between the fixed seats 91 on both sides, and the opening and closing plates 94 are installed in the middle of the chassis 1, convex strips 95 that are equidistantly arranged on the upper end of the opening and closing plates 94 to improve the tea kneading effect, connecting discs 96 that are connected to the lower end of the fixed seats 91, steam pipes 97 connected to the bottom of the connecting discs 96 for steam transmission, and steam ports 98 opened on the upper end of the convex strips 95 for steam exhaust.

[0030] Among them, at least five protruding strips 95 are equidistantly installed along the upper end of the opening and closing plate 94, and each of the corresponding protruding strips 95 has a steam port 98. This ensures that when steam is discharged through the steam port 98, it can moisten the kneaded tea leaves and prevent the tea leaves from breaking during kneading. The outer end of the steam pipe 97 is connected to the steam equipment, and the steam pipe 97 is connected to the inside of each steam port 98. In this way, the transmission and humidification of steam can be efficiently realized, thereby improving the kneading effect of the tea leaves.

[0031] The working principle is as follows:

[0032] First, after the tea leaves are placed inside the tea canister 7, the drive motor 82 causes the first bevel gear 83 and the second bevel gear 84, connected to the bottom output end, to mesh and drive each other. This causes the screw 85, connected to the upper end of the second bevel gear 84, to rotate. As the screw 85 rotates, the movable sleeve 87, threaded to the outside of the screw 85, moves downward, engaging with the first guide groove 88 on the front side of the guide cylinder 86. As the movable sleeve 87 moves downward, the rotating arm 810, which is sleeved on the outside of the guide cylinder 86 and connected to the outside of the movable sleeve 87, also moves downward, connecting with the vertical rod 811 on one side of the rotating arm 810. The lower end of the pressure plate 812 is pressed down, so that the pressure plate 812 presses down the tea placed inside the tea barrel 7. At this time, the drive wheel 3 at the outer end of the side support 2 can drive the rotating shaft 4 installed inside the side support 2 to rotate rapidly. As the rotating shaft 4 rotates, the upper end connecting arm 5 connected to the rotating shaft 4 will cooperate with the connecting arms 5 installed at the upper end of the other two side supports 2 to achieve the bias movement of the connecting ring 6 on the outside of the tea barrel 7. In this way, the tea barrel 7 will move in a biased manner, so that the tea inside the tea barrel 7 can achieve rapid kneading between the base plate 1 and the tea barrel 7.

[0033] The multiple protruding strips 95 installed on the upper end of the opening and closing plate 94 can enhance the kneading effect and improve the quality of tea processing. Simultaneously, the steam pipe 97, which connects the connecting plate 96 to the lower end of the opening and closing plate 94, can be connected to an external steam generator to assist in steam transmission. Steam enters between the connecting plate 96 and the opening and closing plate 94 along the steam pipe 97 and exits through the steam vents 98 located on the upper ends of the protruding strips 95, thus aiding in the steam humidification of drier tea leaves, improving the moisture content during kneading, and preventing... During the rolling process of relatively dry tea leaves, breakage occurs, affecting the overall production and preparation effect. At the same time, the old leaves can be moistened to improve the overall rolling and shaping quality. After rolling, the blocking effect of the baffle 10 on the opening and closing plate 94 can be released by moving the baffle 10 installed at the lower end of the base plate 1. Then, by shaking the rocker arm 93, the connecting rod 92 will be rotated synchronously. As a result, the connecting rod 92 will drive the opening and closing plate 94, so that the opening and closing plate 94 will open from the middle of the lower end of the base plate 1 to quickly discharge the rolled tea leaves.

[0034] Secondly, when the tea leaves need to be placed and kneaded again, the motor 82 can be driven again to achieve the meshing transmission of the first bevel gear 83 and the second bevel gear 84. At this time, when the screw 85 rotates, the external threaded movable sleeve 87 will move upward. As the movable sleeve 87 moves upward, the rotating arm 810, which is sleeved on the outside of the guide cylinder 86 and connected to the outside of the movable sleeve 87, will cooperate with the guide of the first guide groove 88 to achieve a pre-moving upward movement. In this way, the vertical rod 811 will move upward synchronously, so that the vertical rod 811 pulls the pressure plate 812 upward. When the movable sleeve 87 moves upward to the position of the second guide groove 89, it will perform a self-rotation movement through the inclined direction of the second guide groove 89. In this way, the rotating arm 810 connected to the outside of the movable sleeve 87 will rotate synchronously along the upper outer side of the guide cylinder 86. Thus, the vertical rod 811 can realize the upward movement and rotation opening steps of the pressure plate 812 in sequence, so as to quickly expose the upper opening of the tea barrel 7 and carry out the subsequent tea leaf placement and kneading preparation activities.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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.
