Description

Technical Field

[0001] The invention relates to the technical field of tea processing, in particular to a tea leaf twisting machine operating at a constant temperature. Background Art

[0002] Currently in the process of modern tea production, tea rolling is the next tea processing step after the tea leaves are withered. It usually requires the use of a rolling machine to roll the tea leaves into strips to prevent the tea fiber tissue from being damaged and to roll the tea leaves into the required shape for easy storage. The twisting action can also destroy the tissue cells of the tea leaves after withering, allowing the substances contained in the tea leaves to penetrate the surface of the tea leaves and increase the concentration of the tea leaves when brewing.

[0003] During the rolling process, since some tea leaves need to be hot-twisted during rolling, and the rolling machine itself does not have a heating function and cannot meet the hot-twisting requirements, the device has certain limitations when in use. In order to overcome the above-mentioned defects, a tea processing and rolling device with application number 2023236533357 is provided. By setting a heating device, if hot-twisting is required when rolling the tea leaves, the electric heating rod can be operated to heat the bottom of the rolling disk through the electric heating rod to heat the tea leaves on the rolling disk to achieve hot-twisting. The operation of the second motor can drive the fan blades to rotate, and the rotation of the fan blades accelerates the air flow at the bottom of the rolling disk to avoid the electric heating rod from continuously heating the bottom of the rolling disk as much as possible, causing the temperature of the rolling disk to be too high. Although the above technology can complete the hot twisting of tea leaves, in the actual working process, when the tea leaves are rolled on the rolling disk, they are only heated by the electric heating rod fixed at the bottom of the rolling disk, which is prone to uneven heating, resulting in poor hot twisting effect.

[0004] In view of the above problems, it is urgent to carry out innovative design based on the original equipment. Therefore, we proposed a constant temperature tea twisting machine that can solve the above problems well. Summary of the invention

[0005] The purpose of the present invention is to provide a constant temperature tea twisting machine to solve the problem that when the tea is rolled on a twisting plate, it is heated only by an electric heating rod fixed at the bottom of the twisting plate, which is prone to uneven heating and leads to poor heat twisting effect.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a tea leaf twisting machine operating at a constant temperature, comprising a twisting plate, a twisting barrel is arranged above the twisting plate, the twisting barrel repeatedly twists the tea leaf on the top of the twisting plate through three groups of linkage arms on the outside, wherein the bottoms of two groups of linkage arms are connected to the ground through supporting feet, and a first motor is arranged below the other group of linkage arms, the top output shaft of the first motor is fixedly connected to a rotating shaft, and the rotating shaft is connected to the linkage arm; The top of the rolling barrel is covered with a top cover. A through hole is provided at the bottom of the rolling barrel. A preheating assembly is arranged inside the rolling barrel. The preheating assembly includes a fixing frame fixedly connected to the top of the inner wall of the rolling barrel. A second motor is fixedly installed at the center of the top of the fixing frame. The bottom output shaft of the second motor is fixedly connected to a central shaft. Two groups of vertically distributed mounting frames are formed on the outer walls on both sides of the central shaft. Four preheating rods are limited and clamped inside the four mounting frames. A sliding block is movably arranged inside the mounting frame. The sliding block limits the preheating rod inside the mounting frame. A fastening screw is sleeved on the top of the sliding block. The end of the fastening screw is threadedly connected to the outer wall of the central shaft; An installation disk is arranged below the rolling disk. A heating curved pipe is installed inside the installation disk; During use, open the top cover to put the tea leaves into the rolling barrel. Start the second motor to drive the central shaft to rotate. The preheating rods installed on the outside thereof rotate synchronously to stir the put-in tea leaves. In this way, the tea leaves can be dispersed and preheated. The preheated tea leaves fall from the through hole at the bottom of the rolling barrel onto the rolling disk. At this time, start the first motor to drive the rotating shaft to rotate, and drive the rolling barrel to perform the rolling operation of the tea leaves on the rolling disk through three groups of linkage arms. At the same time, the heating curved pipe at the bottom of the rolling disk will continuously keep the tea leaves warm and heated. Throughout the process, the tea leaves can always be continuously heated by the preheating rods and the heating curved pipe, and the heat is evenly distributed, effectively improving the rolling effect; and only need to screw out the fastening screw from the outer wall of the central shaft and lift the sliding block upward to disengage from the mounting frame, then the preheating rod can be taken out from the inside of the mounting frame, so as to facilitate the disassembly and maintenance of the preheating rod.

[0007] Preferably, the two groups of preheating rods distributed vertically are perpendicular to each other. This structural setting can further increase the evenness of the preheating rods for stirring and preheating the tea leaves.

[0008] Preferably, an annular protrusion is formed on the outer wall of the middle part of the preheating rod. Grooves with dimensions matching this annular protrusion are provided on the inner wall of the mounting frame and the end wall of the sliding block. Through the cooperation of the annular protrusion and the groove, the preheating rod can be symmetrically and stably clamped and installed inside the mounting frame by using the sliding block.

[0009] Preferably, a linkage rod is fixedly connected between the tops of the two sliding blocks at the same height. Through the setting of the linkage rod, the two sliding blocks in a group can be lifted synchronously, thereby increasing the convenience of disassembling the preheating rod.

[0010] Preferably, a first transmission wheel is fixedly connected to the outer wall of the rotating shaft. A rotating block is fixedly connected to the bottom wall of the mounting plate. The rotating block is rotationally limited at the bottom of the rolling and kneading plate. The bottom end of the rotating block penetrates to the outside of the bottom of the mounting plate and is fixedly connected to a second transmission wheel. A transmission belt is commonly connected to the outside of the first transmission wheel and the second transmission wheel. When the rotating shaft rotates, it will drive the first transmission wheel to rotate synchronously. The first transmission wheel continues to drive the second transmission wheel to rotate through the transmission of the transmission belt. The second transmission wheel continues to drive the mounting plate to rotate through the connection of the rotating block. In this way, the heating curved pipe inside the mounting plate will rotate synchronously, thereby improving the uniformity of heating the tea leaves on the top of the rolling and kneading plate.

[0011] Preferably, a fixed cushion table is fixedly installed on the ground flush with the bottom of the support feet. The first motor is fixedly installed on the top of the fixed cushion table. The setting of the fixed cushion table can increase the stability of the first motor during operation.

[0012] Preferably, guide posts are formed at the four corners of the top of the mounting plate. A guide groove is formed on the outer wall of the bottom end of the rolling and kneading plate. The four guide posts are all slidably arranged inside the guide groove. Through the sliding cooperation of the guide posts and the guide groove, when the mounting plate is driven to rotate along the bottom of the rolling and kneading plate, the stability of its axial rotation can be improved to prevent eccentric rotation.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: For this kind of tea leaf rolling and kneading machine with constant temperature operation, through the combined use of the preheating component and the heating curved pipe, the second motor is used to drive the central shaft to drive the preheating rod to rotate, so as to stir and disperse and preheat the tea leaves put into the rolling barrel. The preheated tea leaves fall onto the rolling and kneading plate for rolling and kneading operations. At the same time, the heating curved pipe at the bottom of the rolling and kneading plate will keep the tea leaves warm and heated. Throughout the process, the tea leaves can always be continuously heated by the preheating rod and the heating curved pipe, with uniform heating, effectively improving the hot rolling effect. The specific content is as follows: (1) Through the combined use of the preheating component and the heating curved pipe, the second motor is used to drive the central shaft to rotate. The central shaft drives the preheating rod to rotate synchronously to stir the tea leaves put into the rolling barrel. In this way, the tea leaves can be dispersed and preheated. The preheated tea leaves fall from the bottom through hole of the rolling barrel onto the rolling and kneading plate for rolling and kneading operations. At the same time, the heating curved pipe at the bottom of the rolling and kneading plate will continuously keep the tea leaves warm and heated. Throughout the process, the tea leaves can always be continuously heated by the preheating rod and the heating curved pipe, with uniform heating, effectively improving the hot rolling effect.

[0014] (2) Through the cooperation of the fastening screw and the sliding block, the preheating rod is fixedly clamped inside the mounting frame. Just unscrew the fastening screw from the outer wall of the central shaft and lift the sliding block upward to disengage from the mounting frame, then the preheating rod can be taken out from the inside of the mounting frame, so as to facilitate the disassembly and maintenance of the preheating rod.

[0015] (3) Through the cooperation of the first driving wheel, the rotating block, the mounting disc, the second driving wheel and the transmission belt, when the first motor drives the rotating shaft to rotate for kneading operation, the rotating shaft will drive the first driving wheel to rotate synchronously. The first driving wheel continues to drive the second driving wheel to rotate through the transmission of the transmission belt, and the second driving wheel continues to drive the mounting disc to rotate through the connection of the rotating block. In this way, the heating curved pipe inside the mounting disc will rotate synchronously, thereby improving the uniformity of heating the tea leaves at the top of the kneading disc by the heating curved pipe.

[0016] (4) Through the sliding cooperation of the guiding columns formed at the four corners of the top of the mounting disc and the guiding grooves formed in a circle on the outer wall of the bottom end of the kneading disc, when the mounting disc is driven to rotate along the bottom of the kneading disc, the stability of its axial rotation can be improved to prevent eccentric rotation.

A transmission belt 22 is commonly connected to the outer sides of the first transmission wheel 17 and the second transmission wheel 21. When the rotating shaft 6 rotates, it will drive the first transmission wheel 17 to rotate synchronously. The first transmission wheel 17 continues to drive the second transmission wheel 21 to rotate through the transmission of the transmission belt 22. The second transmission wheel 21 continues to drive the mounting plate 19 to rotate through the connection of the rotating block 18. In this way, the heating curved pipe 20 inside the mounting plate 19 will rotate synchronously, thereby improving the uniformity of the heating of the tea leaves on the top of the rolling plate 1 by the heating curved pipe 20.
