Description

Technical Field

[0001] This utility model relates to the field of tea frying technology, specifically a tea frying and forming machine. Background Technology

[0002] In the tea processing, the frying and shaping process is a key step that determines the quality and appearance of the tea. It uses high temperatures to kill the green and dehydrate the tea leaves, and shapes them into strips, curls, and other characteristics, which directly affect the aroma, taste, and market value of the tea. Existing tea frying and shaping equipment has several limitations in practical applications: First, the stirring mechanism lacks flexibility. Traditional equipment often has a fixed height or rotation trajectory for the stirring shaft, making it impossible to adapt to the amount of tea added to the wok or the stage of frying. This results in uneven frying, easily leading to localized overheating and scorching or under-frying. Second, the unloading operation is cumbersome. Due to the influence of the stirring mechanism, the wok is either fixedly installed or can only be tilted at a small angle. The fried tea must be slowly removed manually. The obstruction caused by the stirring mechanism prevents thorough unloading, increasing labor intensity and potentially causing tea breakage due to improper manual operation, thus affecting the yield. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a tea frying and shaping machine to solve the shortcomings of the existing technology.

[0004] The purpose of this utility model is achieved through the following technical solution: a tea frying and forming machine, including a machine base and a frying pan, one end of which is rotatably mounted on the machine base, the rotation axis of which is horizontally set, a heating cavity is formed between the inner and outer walls of the frying pan, and a plurality of electric heating elements are arranged in the heating cavity. A stirring and frying mechanism is provided on the machine base, the stirring and frying mechanism including a rotating frame, a telescopic shaft and a stirring shaft, the rotating frame being rotatably mounted on the machine base, the rotation axis of which is vertically set, one end of the telescopic shaft being rotatably connected to the rotating frame, and the other end being fixedly connected to the stirring shaft, and a plurality of side stirring shafts being fixed to the side wall of the stirring shaft, the plurality of side stirring shafts being evenly distributed around the circumference of the stirring shaft.

[0005] Furthermore, the telescopic shaft includes a rotating shaft and a sliding shaft. A main shaft is fixed to the top of the telescopic shaft. The main shaft is rotatably connected to a rotating frame via a first bearing. A geared motor is mounted on the rotating frame. The output shaft of the geared motor is connected to the main shaft. A sliding hole is provided at the top of the sliding shaft. The rotating shaft is slidably fitted into the sliding hole. A vertical groove is provided on the side wall of the sliding hole on the sliding shaft. A slider is fixed to the side wall of the rotating shaft. The slider is slidably fitted into the vertical groove. A stirring shaft is coaxially fixed at the end of the sliding shaft away from the rotating shaft.

[0006] Furthermore, a cylinder is vertically mounted on the rotating frame, and a lifting plate is connected to the telescopic shaft of the cylinder. A circular hole is opened on the lifting plate, and a second bearing is installed in the circular hole. The outer ring of the second bearing is fixedly connected to the lifting plate, and the sliding shaft is assembled on the inner ring of the second bearing.

[0007] Furthermore, a rotating spindle is fixed to the bottom of the rotating frame, and the rotating spindle is rotatably connected to the machine base.

[0008] Furthermore, a motor is mounted on the base, the output shaft of the motor is connected to a drive pulley, a driven pulley is mounted on the rotating main shaft, and the drive pulley is connected to the driven pulley via a belt drive.

[0009] Furthermore, a deflection main shaft is fixedly inserted at the end of the wok away from the rotating frame, a support base is fixed on the machine base, the deflection main shaft is rotatably connected to the support base, a lever is fixed on the side wall of the deflection main shaft, a push cylinder is hinged on the machine base, the telescopic shaft of the push cylinder is hinged to the lever, and the hinge axis of the push cylinder is parallel to the axis of the deflection main shaft.

[0010] The beneficial effects of this utility model are: 1. By adjusting the length of the telescopic shaft, the stirring shaft can be extended into the wok, ensuring that the tea leaves are heated evenly and resulting in a better frying effect.

[0011] 2. After frying, the telescopic shaft drives the stirring shaft and the side stirring shaft to detach from the frying pan. Then, through the deflection of the rotating frame, the stirring and frying mechanism is positioned on one side of the frying pan, so that the stirring and frying mechanism does not affect the deflection of the frying pan. The tea leaves can be discharged by deflecting the frying pan. This solves the problem of limited tilt angle of the frying pan and incomplete discharge caused by the obstruction of the stirring mechanism in traditional equipment. The tea leaves can slide down quickly by their own gravity, reducing manual assistance, reducing labor intensity, and avoiding tea leaf breakage caused by manual operation, thus improving the yield.

Detailed Implementation

[0013] Example 1 like Figures 1 to 3 As shown, a tea frying and forming machine includes a base 1 and a frying pan 2. One end of the frying pan 2 is rotatably mounted on the base 1. The rotation axis of the frying pan 2 is horizontally set. A heating chamber is formed between the inner and outer walls of the frying pan 2. Several electric heating elements are arranged in the heating chamber. A stirring and frying mechanism is provided on the base 1. The stirring and frying mechanism includes a rotating frame 3, a telescopic shaft 4, and a stirring shaft 5. The rotating frame 3 is rotatably mounted on the base 1. The rotation axis of the rotating frame 3 is vertically set. One end of the telescopic shaft 4 is rotatably connected to the rotating frame 3, and the other end is fixedly connected to the stirring shaft 5. Multiple side stirring shafts 6 are fixed to the side wall of the stirring shaft 5. The multiple side stirring shafts 6 are evenly distributed around the circumference of the stirring shaft 5. The telescopic shaft 4 first extends to drive the stirring shaft 5 and the side stirring shafts 6 to stir. Shaft 6 extends into wok 2, and then the tea leaves to be fried are put into wok 2. The telescopic shaft 4 drives the stirring shaft 5 and the side stirring shaft 6 to rotate, thereby turning the tea leaves and making them evenly heated. After frying, the telescopic shaft 4 retracts, driving the stirring shaft 5 and the side stirring shaft 6 to move above wok 2. Then the rotating frame 3 drives the stirring and frying mechanism to deflect, so that the stirring and frying mechanism does not affect the deflection of wok 2. The tea leaves can be discharged by deflecting the wok. This solves the problem of limited wok tilt angle and incomplete discharge caused by the stirring mechanism blocking the traditional equipment. The tea leaves can slide down quickly by their own gravity, reducing manual assistance, reducing labor intensity, and avoiding tea leaf breakage caused by manual operation, thus improving the yield.

[0014] Example 2 Based on Embodiment 1, a deflection main shaft 22 is fixedly inserted at the end of the wok 2 away from the rotating frame 3. A support base 23 is fixed on the machine base 1. The deflection main shaft 22 is rotatably connected to the support base 23. A lever 24 is fixed to the side wall of the deflection main shaft 22. A push cylinder 25 is hinged on the machine base 1. The telescopic shaft of the push cylinder 25 is hinged to the lever 24. The hinge axis of the push cylinder 25 is parallel to the axis of the deflection main shaft 22. When the tea is fried, the push cylinder 25 is activated. The push cylinder 25 drives the deflection main shaft 22 to deflect through the lever 24, causing the wok 2 to deflect away from the rotating frame 3 and tilt. This allows the tea to be discharged by its own gravity. With the help of workers, the tea in the wok 2 is completely poured out, realizing a fast and thorough tea discharge operation.

[0015] Example 3 Based on Example 2, such as Figures 1 to 3 As shown, the telescopic shaft 4 includes a rotating shaft 7 and a sliding shaft 8. A main shaft 9 is fixed to the top of the telescopic shaft 4. The main shaft 9 is rotatably connected to the rotating frame 3 via a first bearing. A reduction motor 10 is mounted on the rotating frame 3. The output shaft of the reduction motor 10 is connected to the main shaft 9. A sliding hole 11 is provided on the top of the sliding shaft 8. The rotating shaft 7 is slidably fitted into the sliding hole 11. A vertical groove 12 is provided on the side wall of the sliding hole 11 of the sliding shaft 8. A slider 13 is fixed to the side wall of the rotating shaft 7. The slider 13 is slidably fitted into the vertical groove 12. A stirring shaft 5 is coaxially fixed to the end of the sliding shaft 8 away from the rotating shaft 7. A cylinder 14 is vertically mounted on the rotating frame 3. The telescopic shaft of the cylinder 14 is connected to a lifting plate 15. A circular groove is provided on the lifting plate 15. A second bearing 16 is installed inside the hole. The outer ring of the second bearing 16 is fixedly connected to the lifting plate 15. The sliding shaft 8 is assembled on the inner ring of the second bearing 16. The sliding shaft 8 can slide on the rotating shaft 7 through the cooperation of the vertical sliding groove 12 and the slider 13. However, the sliding shaft 8 does not have relative rotational freedom between the rotating shaft 7 and the rotating shaft 7. When the reduction motor 10 drives the rotating shaft 7 to rotate through the main shaft 9, the rotating shaft 7 drives the sliding shaft 8 to rotate, which in turn drives the stirring shaft 5 and the side stirring shaft 6 to rotate to complete the stir-frying of the tea. After the stir-frying is completed, the cylinder 14 drives the lifting plate 15 to move upward, so that the lifting plate 15 drives the sliding shaft 8 to slide upward, thereby disengaging the stirring shaft 5 and the side stirring shaft 6 from the frying pan 2, making it convenient to discharge the tea.

[0016] Example 4 Based on Example 3, such as Figure 1 As shown, a rotating main shaft 17 is fixed at the bottom of the rotating frame 3. The rotating main shaft 17 is rotatably connected to the machine base 1. A motor 18 is installed on the machine base 1. The output shaft of the motor 18 is connected to a drive pulley 19. A driven pulley 20 is mounted on the rotating main shaft 17. The drive pulley 19 is connected to the driven pulley 20 via a belt 21. The motor 18 drives the drive pulley 19 to rotate. The drive pulley 19 drives the driven pulley 20 to rotate via the belt 21. The driven pulley 20 drives the rotating frame 3 to deflect via the rotating main shaft 17, which is used to adjust the position of the stirring and frying mechanism and complete the switching between tea frying and tea discharge states.
