Description

Technical Field

[0001] This utility model relates to the technical field of tea processing, and in particular to a tea rolling machine. Background Technology

[0002] Rolling is the initial shaping process in tea processing. Rolling creates a tightly rolled and curved shape and also affects the improvement of the 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 facilitates material transformation. Because tea processing involves large quantities, manual labor is relatively inefficient; therefore, rolling machines are needed to perform the rolling operation.

[0003] A search revealed that patent CN221152828U discloses a continuous tea kneading machine. In operation, tea leaves are first added to a storage cylinder. A pressing mechanism compresses the tea leaves into the cylinder, with the leaves at the bottom falling onto the kneading disc. A drive mechanism then rotates the storage cylinder, kneading the tea leaves on the ribs. After kneading, an electric telescopic rod lowers a lifting plate, which in turn lowers a tilting mechanism and the kneading disc. A second motor drives a first gear and a second gear, which in turn rotates a support shaft. This rotation of the support shaft tilts the kneading disc to an inclined position, facilitating the falling tea leaves into the collection box. Simultaneously, a fan delivers airflow into the main body tube, which is then blown onto the kneading disc through multiple nozzles, further ensuring thorough tea leaf removal. In summary, this invention offers convenient tea kneading, easy and thorough feeding.

[0004] While the patent does have some practicality in use, there is still room for improvement. For example, the patent uses a fan to deliver airflow into the main tube and blows it onto the kneading disc through multiple nozzles. The airflow is used to blow the tea leaves off the kneading disc for collection. However, because the tea leaves are very light, they may fall off the kneading disc in large quantities after being blown by the airflow. This results in the tea leaves being scattered all over the ground, causing a lot of waste. At the same time, it is difficult to collect some tea powder, making it difficult to clean up the tea powder, resulting in poor tea leaf collection. Utility Model Content

[0005] The purpose of this utility model is to provide a tea kneading machine to solve the problem mentioned in the background art that existing kneading machines are prone to scattering tea leaves over a wide area due to excessive wind force when collecting tea leaves, making them difficult to collect and clean.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a tea kneading machine, comprising a worktable and a collection frame, wherein a circular frame is fixedly connected to the upper surface of the worktable, a kneading disc is inserted into the inner wall of the circular frame, three sets of drive structures are fixedly connected to the upper surface of the worktable, a kneading assembly is fixedly connected to the output end of the three sets of drive structures, two feeding assemblies are fixedly connected to the upper surface of the worktable, an auxiliary assembly is fixedly connected to the left side of the worktable, the kneading assembly includes a kneading cylinder, a support frame is fixedly connected to the surface of the kneading cylinder, a strip plate is fixedly connected to the top of the support frame, a lead screw is threadedly connected to the upper surface of the strip plate, a circular cover is fixedly connected to the bottom end of the lead screw, and a handwheel is fixedly connected to the top end of the lead screw;

[0007] The feeding assembly includes cylinders, with a first fixed frame and a second fixed frame fixedly connected to the output ends of the two cylinders respectively. A first motor is fixedly connected to the inner wall of the first fixed frame, and a circular rod is fixedly connected to the output end of the first motor.

[0009] Preferably, the position of the circular cap corresponds to the position of the kneading cylinder, and the diameter of the circular cap is adapted to the inner diameter of the kneading cylinder.

[0010] Preferably, the front end of the circular rod is rotatably connected to the back of the second fixed frame, and the top end of the connecting rod is fixedly connected to the lower surface of the kneading disc.

[0011] Preferably, a circular through hole adapted to the kneading disc is provided on the upper surface of the workbench at a position corresponding to the circular frame.

[0012] Preferably, the bottom end of the threaded rod is rotatably connected to the inner bottom wall of the groove, and the slider is threadedly connected to the threaded rod.

[0013] Preferably, the circular plate is slidably connected to the surfaces of the two limiting rods respectively, and one end of the spring overlaps with the inner wall of the sleeve, while the other end overlaps with the side of the circular plate.

[0014] Preferably, the right end of the sleeve is provided with a round hole adapted to the push rod, and the left side of the worktable is provided with a strip hole adapted to the electric push rod.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This tea kneading machine, through the setting of the feeding component and auxiliary components, in use, uses two cylinders to drive the kneading disc to descend below the worktable. The first motor, circular rod, fixed block and connecting rod drive the kneading disc to rotate to an inclined angle. At the same time, the electric push rod drives the sleeve to move to the right so that the cleaning brush contacts the surface of the kneading disc. After the second motor and the third motor are started, they can drive the cleaning brush to descend through the slider. The cleaning brush is squeezed by the U-shaped frame and the top rod, which causes the spring to deform. The reaction force generated by the spring can keep the cleaning brush pressed against the kneading disc. The third motor drives the cleaning brush to rotate, which can scrape all the tea leaves on the kneading disc into the collection frame, without the problem of large-scale falling, without the waste of tea leaves and the difficulty of cleaning. The collection effect of tea leaves is better. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 This utility model provides a technical solution: a tea kneading machine, including a workbench 1 and a collection frame 2. A circular frame 3 is fixedly connected to the upper surface of the workbench 1. A kneading disc 4 is inserted into the inner wall of the circular frame 3. Three sets of drive structures 5 are fixedly connected to the upper surface of the workbench 1. A kneading component is fixedly connected to the output end of the three sets of drive structures 5. Two feeding components are fixedly connected to the upper surface of the workbench 1. An auxiliary component is fixedly connected to the left side of the workbench 1. The kneading component includes a kneading cylinder 6. A support frame 7 is fixedly connected to the surface of the kneading cylinder 6. A strip plate 8 is fixedly connected to the top of the support frame 7. A lead screw 9 is threadedly connected to the upper surface of the strip plate 8. A circular cover 10 is fixedly connected to the bottom end of the lead screw 9. A handwheel 11 is fixedly connected to the top end of the lead screw 9.

[0024] The feeding assembly includes cylinders 12. The output ends of the two cylinders 12 are respectively fixedly connected to a first fixed frame 13 and a second fixed frame 14. The inner wall of the first fixed frame 13 is fixedly connected to a first motor 15. The output end of the first motor 15 is fixedly connected to a circular rod 16. The surface of the circular rod 16 is fixedly connected to a fixed block 17. The upper surface of the fixed block 17 is fixedly connected to a connecting rod 18.

[0025] The auxiliary components include a strip frame 19, a second motor 20 fixedly connected to the upper surface of the strip frame 19, a threaded rod 21 fixedly connected to the output end of the second motor 20, a slide groove on the right side of the strip frame 19, a slider 22 slidably connected to the inner wall of the slide groove, an electric push rod 23 fixedly connected to the right side of the slider 22, a sleeve 24 fixedly connected to the output end of the electric push rod 23, a circular plate 25 slidably connected to the inner wall of the sleeve 24, two limiting rods 26 fixedly connected to the inner wall of the sleeve 24, and springs 27 sleeved on the surfaces of the two limiting rods 26, a top rod 28 fixedly connected to the right side of the circular plate 25, a U-shaped frame 29 fixedly connected to the right end of the top rod 28, a third motor 30 fixedly connected to the front of the U-shaped frame 29, a rotating shaft 31 fixedly connected to the output end of the third motor 30, and a cleaning brush 32 fixedly connected to the surface of the rotating shaft 31.

[0026] Furthermore, the position of the circular cover 10 corresponds to the position of the kneading cylinder 6, and the diameter of the circular cover 10 is adapted to the inner diameter of the kneading cylinder 6. The circular cover 10 can be inserted into the kneading cylinder 6 and squeeze the tea leaves inside the kneading cylinder 6 to move downwards, thereby falling onto the kneading disc 4.

[0027] Furthermore, the front end of the circular rod 16 is rotatably connected to the back of the second fixed frame 14, and the top end of the connecting rod 18 is fixedly connected to the lower surface of the kneading disc 4. The circular rod 16 can rotate and drive the kneading disc 4 to rotate through the fixed block 17 and the connecting rod 18, thereby causing the kneading disc 4 to tilt at an angle.

[0028] Furthermore, a circular through hole adapted to the kneading disc 4 is provided on the upper surface of the workbench 1 at a position corresponding to the circular frame 3, allowing the kneading disc 4 to fall to the lower surface of the workbench 1 through the circular through hole.

[0029] Furthermore, the bottom end of the threaded rod 21 is rotatably connected to the inner bottom wall of the groove, and the slider 22 is threadedly connected to the threaded rod 21. The second motor 20 can drive the threaded rod 21 to rotate, thereby driving the slider 22 to move up and down.

[0030] Furthermore, the circular plate 25 is slidably connected to the surfaces of the two limiting rods 26 respectively, and one end of the spring 27 overlaps with the inner wall of the sleeve 24, and the other end overlaps with the side of the circular plate 25. The circular plate 25 can move left and right on the surfaces of the two limiting rods 26, thereby causing the spring 27 to produce a deformation effect.

[0031] Furthermore, the right end of the sleeve 24 is provided with a round hole that matches the push rod 28, and the left side of the worktable 1 is provided with a strip hole that matches the electric push rod 23. The push rod 28 can press the circular plate 25 to the left through the round hole, while the electric push rod 23 can move up and down in the strip hole.

[0032] Working principle: First, pour the tea leaves into the kneading cylinder 6. Then, turn the handwheel 11 to move the screw 9 down and drive the circular cover 10 to squeeze the tea leaves downward. The tea leaves leak out from the bottom of the kneading cylinder 6 and fall onto the kneading disc 4. At this time, the drive structure 5 is activated, driving the kneading cylinder 6 to rotate on the kneading disc 4, thus kneading the tea leaves. After kneading, the two cylinders 12 drive the first fixed frame 13 and the second fixed frame 14 to descend. Through the circular rod 16, the fixed block 17, and the connecting rod 18, the kneading disc 4 is driven down to a position below the worktable 1. At this time, the first motor 15 drives the circular rod 16 to rotate, thereby driving the kneading disc 4 to rotate to an inclined angle through the fixed block 17 and the connecting rod 18. At this time, the electric push rod 23 is activated, driving the sleeve 24 to move to the right until the cleaning brush 32 contacts the surface of the kneading disc 4. Then, the second motor 20 and the third motor 30 are activated. The second motor 20 drives the threaded rod 21 slowly. The rotation allows the slider 22 to slowly descend within the strip frame 19. Simultaneously, the third motor 30 drives the cleaning brush 32 to rotate, enabling the cleaning brush 32 to contact the surface of the kneading disc 4 and causing the tea leaves on the surface of the kneading disc 4 to fall into the collection frame 2. As the slider 22 continues to descend, the cleaning brush 32 can press the top rod 28 to the left through the U-shaped frame 29. The kneading disc 4 is prevented from shaking due to the self-locking function of the first motor 15. The further the slider 22 moves downward, the more the top rod 28 presses the circular plate 25 to the left, thereby causing the two springs 27 to deform. The reaction force generated by the two springs 27 can keep the cleaning brush 32 pressed firmly against the surface of the kneading disc 4, thus ensuring that the cleaning brush 32 can scrape all the tea leaves on the surface of the kneading disc 4 into the collection frame 2, preventing the tea leaves from falling over a large area. This results in a better collection effect and avoids waste and cleaning problems.

[0033] 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.
