A telescopic rod is installed on the lower surface of the mounting plate, and the telescopic rod is fixedly connected to a second motor mounting platform. A second motor is provided at the bottom, and the second motor is connected to a kneading block through a rotating shaft. A first motor mounting platform is provided at the lower part of the workbench, and a first motor is provided on the first motor mounting platform. The first motor is connected to a pulley through a rotating shaft, and the pulley is connected to an active eccentric shaft through a belt. The active eccentric shaft is rotatably connected to a kneading barrel, and a first kneading pattern is provided on the bottom surface of the kneading barrel, and a second kneading pattern is provided on the lower surface of the kneading block. A drainage port is also provided on the bottom surface of the kneading barrel, and a filter screen is provided on the drainage port. It also includes a driven eccentric shaft, and three driven eccentric shafts are provided on the workbench. The three driven eccentric shafts are evenly and fixedly connected to the kneading barrel at equal angles. However, the efficient tea kneading device still has the following disadvantages in actual use:

[0003] 1. The traditional rolling device can only adjust the distance between the entire rolling mechanism and the tea leaves according to the thickness of the tea leaves and the required rolling force. The entire rolling surface is adjusted, so it is easy to cause some tea leaves to be damaged during the rolling process, and it is inconvenient to adjust the rolling force of part of the rolling surface;

[0004] 2. During the rolling process, most of the tea leaves will be scattered at the edge of the box, resulting in uneven rolling. The traditional rolling device lacks a structure to improve the uniformity of tea leaf distribution during the rolling process.

[0005] In view of the above problems, it is urgent to carry out innovative design based on the original tea rolling machine. Summary of the invention

[0006] The purpose of the present invention is to provide a rolling machine for green tea processing with adjustable strength, so as to solve the problems proposed in the above-mentioned background technology that part of the tea leaves are easily damaged during the rolling process, it is inconvenient to adjust the rolling strength of part of the rolling surface, and most of the tea leaves will be scattered at the edge of the box during the rolling process, so uneven rolling will occur.

[0008] include:

[0009] A kneading plate is fixedly mounted on the bottom of the connecting shaft, a rubber protective pad is pasted on the lower end surface of the kneading plate, a movable groove is provided inside the kneading plate, and a movable roller is movably provided inside the movable groove, an adjusting rod is movably penetrated through the side of the kneading plate, and a worm is fixedly sleeved on one end of the adjusting rod close to the kneading plate, and a worm wheel is meshed on the side of the worm;

[0010] A material storage box is movably mounted inside the processing table, a fixing groove is provided in the processing table outside the material storage box, a fixing rod is fixed to the side of the material storage box, and a return spring is wound around the outside of the fixing rod;

[0011] The first magnet is fixed to the bottom of the storage box, the second magnet is movably arranged below the first magnet, and a movable rod is fixed to the lower end surface of the second magnet, and another return spring is wound around the outer side of the movable rod, the bottom of the movable rod is connected to a piston plate, and a connecting cavity is opened in the processing table outside the piston plate.

[0012] Preferably, the movable roller forms a longitudinal sliding structure through the movable groove and the kneading plate, and the movable roller is symmetrically distributed about the vertical axis of the kneading plate, and the bottom of the movable roller is in contact with the upper surface of the protective pad. At the same time, the kneading plate is eccentrically arranged with respect to the center of the storage box. Therefore, the kneading plate can knead the tea leaves through a plane, and can also drive the protective pad to bulge through the movable roller after moving downward, thereby achieving kneading of different intensities.

[0013] Preferably, a movable cylinder is fixed inside the worm wheel and penetrates therethrough, and connecting rods are threadedly connected to both ends of the movable cylinder, and a guide block is fixed to the end of the connecting rod away from the movable cylinder, and the movable cylinder can be driven to rotate through the transmission of the worm and the worm wheel, so that the two guide blocks can be driven to approach or move away from each other through the threaded connection between the connecting rod.

[0014] Preferably, the side of the guide block close to the movable roller is set as an inclined surface, and the inclined surface of the guide block contacts the top of the movable roller, and the moving directions of the two guide blocks are set in opposite directions. When the guide block pushes the movable roller, it can drive the movable roller to slide down in the movable groove and drive the protective pad under the movable groove to bulge downward.

[0015] Preferably, the material storage box forms a horizontal relative moving structure through a fixed groove and a processing table, and the fixed rod and the processing table are slidably connected, a piston block is fixed to the end of the fixed rod away from the material storage box, and a fixed cavity is opened in the processing table outside the piston block, when the material storage box is pushed, it can move horizontally in the fixed groove and drive the fixed rod to slide on the processing table.

[0016] Preferably, the top of the fixed cavity and one end of the gas pipe are connected to each other, and a connecting sleeve block is fixed to the other end of the gas pipe, and the connecting sleeve block is sleeved on the outside of the connecting shaft. At the same time, the connecting sleeve block and the connecting shaft are rotatably connected. When the piston block moves, the gas in the fixed cavity can be squeezed into the gas pipe, and then enters the connecting shaft through the connecting sleeve block and the fixed hole.

[0017] Preferably, the connecting sleeve block is connected to the connecting shaft through a fixing hole, and the fixing hole is arranged on the surface of the connecting shaft inside the connecting sleeve block, and the lower end side of the connecting shaft is connected to the inside of the kneading plate through a fixing tube, and an air outlet is reserved at the center of the lower surface of the kneading plate. The gas in the connecting shaft can enter the inside of the kneading plate through the fixing tube, so that it has the effect of dispersing the tea leaves when discharged from the air outlet.

[0018] Preferably, the first magnet and the second magnet are magnets of the same polarity, and the second magnet forms a longitudinal sliding structure through a movable rod and a processing table. The edge of the piston plate slides in contact with the inner wall of the connecting cavity.

When the second magnet descends, the piston plate can be driven to descend synchronously, and the gas in the connecting chamber is transmitted to the connecting hose through the air supply channel.

[0020] Preferably, the connecting hose is connected to the storage box and the air outlet nozzle, and the air outlet nozzle is fixed at an equal angle to the inner wall of the storage box, and the outer diameter of the storage box is smaller than the length of the fixed groove. Finally, the gas can be discharged through the air outlet nozzle and blow the tea leaves from all sides to the center of the storage box to avoid uneven kneading of the tea leaves.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: the green tea processing rolling machine with adjustable strength can adjust part of the rolling surface on the rolling plate according to the thickness of the tea leaves and the strength required for rolling, thereby reducing the damage to the tea leaves, and during the rolling process, it can ensure the uniformity of the distribution of the tea leaves in the material storage box, thereby improving the rolling efficiency. The specific contents are as follows:

[0022] 1. The movable cylinder can be driven to rotate through the transmission of the worm and the worm wheel, so that the two guide blocks can be driven to move closer to or farther away from each other through the threaded connection between the connecting rod. When they move away from each other, the movable roller can be pushed to slide down in the movable groove and the protective pad can be pushed to bulge downward, so that the kneading force of part of the kneading surface can be adjusted without causing damage to a large amount of tea. When the guide blocks are close to each other, the movable roller is automatically moved upward by the resilience of the protective pad to ensure that the lower surface of the kneading plate is flat;

[0023] 2. When the kneading plate rotates and contacts the left side of the material storage box, the material storage box can be pushed to move in the fixed groove. By setting the return spring, the material storage box can be moved back and forth by the rotation of the kneading plate, thereby ensuring the uniformity of the distribution of the tea leaves. At the same time, when the material storage box moves to the right, the gas in the fixed cavity can be squeezed into the gas pipe through the piston block, and then enters the kneading plate through the connecting shaft and the fixed pipe. Therefore, during the rotating kneading process, the blown gas can accelerate the drying of the moisture on the surface of the tea leaves after withering.

[0024] 3. When the storage box moves, the first magnet and the second magnet are displaced, so that the second magnet can be raised by the resilience of the reset spring. When the storage box moves to the state where the first magnet and the second magnet overlap, the repulsion performance can drive the second magnet, the movable rod and the piston plate to move downward, and then the gas in the connecting chamber is transported to the storage box through the gas transmission channel and the connecting hose, and finally discharged from the air outlet nozzle, and the tea leaves are blown to the center from all sides of the storage box, avoiding uneven kneading and ensuring the uniform distribution of the tea leaves.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

A worm 10 is provided at the end fixing sleeve, and a worm wheel 11 is meshed on the side of the worm 10; a material storage box 15 is movably mounted inside the processing table 1, a fixing groove 16 is provided in the processing table 1 outside the material storage box 15, and a fixing rod 17 is fixed to the side of the material storage box 15, and a return spring 18 is wound around the outside of the fixing rod 17; a first magnet 26 is fixed to the bottom of the material storage box 15, a second magnet 27 is movably provided below the first magnet 26, and a movable rod 28 is fixed to the lower end surface of the second magnet 27, and another return spring 18 is wound around the outside of the movable rod 28, a piston plate 29 is connected to the bottom of the movable rod 28, and a connecting cavity 30 is provided in the processing table 1 outside the piston plate 29.

[0037] like Figure 1-4 As shown in the figure, the movable roller 8 forms a longitudinal sliding structure through the movable groove 7 and the kneading plate 5, and the movable roller 8 is symmetrically distributed about the vertical axis of the kneading plate 5, and the bottom of the movable roller 8 is in contact with the upper surface of the protective pad 6, and the kneading plate 5 is eccentrically arranged with respect to the center of the storage box 15; a movable cylinder 12 is fixedly penetrated inside the worm gear 11, and connecting rods 13 are threadedly connected at both ends of the movable cylinder 12, and a guide block 14 is fixed at the end of the connecting rod 13 away from the movable cylinder 12; the side of the guide block 14 close to the movable roller 8 is set as an inclined surface, and the inclined surface of the guide block 14 is in contact with the top of the movable roller 8, and the moving directions of the two guide blocks 14 are set in opposite directions. When the kneading force needs to be adjusted, it can be adjusted by rotating the adjustment The node rod 9 drives the worm 10 to rotate synchronously, and then drives the movable cylinder 12 to rotate through the meshing with the worm wheel 11, so that the threaded connection between the movable cylinder 12 and the connecting rod 13 can drive the two guide blocks 14 to approach or move away from each other. When moving away from each other, the movable roller 8 can be pushed to slide down in the movable groove 7, and then the protective pad 6 below it can be pushed to bulge, so that the distance between the protective pad 6 below the movable roller 8 and the tea leaves is reduced, thereby increasing the kneading strength. When there is no need to adjust the movable roller 8, the adjusting rod 9 can be rotated in the opposite direction, so that the movable roller 8 can be driven to move up through the resilience of the protective pad 6, so that the lower surface of the kneading plate 5 is in a plane state, thereby realizing plane kneading, so as to meet the kneading requirements of different strengths;

[0038] like Figure 1 and Figure 5 As shown, the material storage box 15 forms a horizontal relative movement structure with the processing table 1 through the fixed groove 16, and the fixed rod 17 and the processing table 1 are slidably connected. A piston block 19 is fixed to the end of the fixed rod 17 away from the material storage box 15, and a fixed cavity 20 is opened in the processing table 1 outside the piston block 19. After adjusting the required kneading force, the motor 3 drives the connecting shaft 4 to rotate through the pulley mechanism, thereby driving the kneading plate 5 to rotate in the material storage box 15 to knead the tea leaves. When the kneading plate 5 rotates and contacts the left end of the material storage box 15, the material storage box 15 can be pushed to move in the fixed groove 16 and drive the fixed rod 17 to slide on the processing table 1. When the kneading plate 5 does not push the material storage box 15, the resilience of the reset spring 18 can drive the material storage box 15 to return to its original position. In this way, the continuous rotation of the kneading plate 5 can realize the reciprocating horizontal movement of the material storage box 15, improve the uniformity of the distribution of the tea leaves in the material storage box 15, and thus improve the comprehensiveness of the kneading.

[0039] like Figure 1 and Figure 6-7As shown, the top of the fixed cavity 20 and one end of the gas pipe 21 are connected to each other, and the other end of the gas pipe 21 is fixed with a connecting sleeve block 22, and the connecting sleeve block 22 is sleeved on the outside of the connecting shaft 4, and the connecting sleeve block 22 and the connecting shaft 4 are rotatably connected. When the storage box 15 moves to the left, it drives the fixed rod 17 and the piston block 19 to move to the left. When the storage box 15 is not pushed, the piston block 19 can be driven to move quickly to the right through the resilience of the return spring 18, and the gas in the fixed cavity 20 is pushed into the gas pipe 21; the connecting sleeve block 22 is connected to the connecting shaft 4 through the fixing hole 23, and the fixing hole 23 is set The surface of the connecting shaft 4 inside the connecting sleeve 22, and the lower end side of the connecting shaft 4 is connected to the inside of the kneading plate 5 through the fixed pipe 24, and the air outlet 25 is reserved at the center of the lower surface of the kneading plate 5. The gas in the air supply pipe 21 can enter the connecting shaft 4 through the fixed hole 23, and the setting of the connecting sleeve 22 will not hinder the rotation of the connecting shaft 4. Then the gas enters the kneading plate 5 through the fixed pipe 24, and is discharged from the air outlet 25 to the surface of the kneaded tea leaves, which can remove the excess moisture on the surface of the tea leaves after withering, and remove it synchronously during the kneading process, and no additional air supply equipment is needed;

[0040] like Figure 1 and Figure 8-9 As shown, the first magnet 26 and the second magnet 27 are magnets of the same polarity, and the second magnet 27 forms a longitudinal sliding structure through the movable rod 28 and the processing table 1, and the edge of the piston plate 29 slides in contact with the inner wall of the connecting chamber 30; the connecting chamber 30 is connected to the connecting hose 32 through the air supply channel 31, and the air supply channel 31 is arranged inside the processing table 1, and the two ends of the connecting hose 32 are respectively connected to the inner corner of the fixed groove 16 and the outer corner of the storage box 15; the connecting hose 32 is connected to the air outlet nozzle 33 through the storage box 15, and the air outlet nozzle 33 is fixed at an equal angle to the inner wall of the storage box 15, and the outer diameter of the storage box 15 is smaller than the length of the fixed groove 16. When the storage box 15 moves to the left, it drives the first magnet 26 The second magnet 27 is staggered with the second magnet 27, so that the second magnet 27 is not subjected to the repulsive force, and the second magnet 27 can be driven to move upward by the resilience of the reset spring 18. When the storage box 15 drives the first magnet 26 to move to just above the second magnet 27, the repulsion between the two can drive the second magnet 27 to move downward, and the piston plate 29 is driven downward synchronously by the movable rod 28 to push the gas in the connecting chamber 30 into the gas delivery channel 31. In this way, during the movement of the storage box 15, the gas can also enter the storage box 15 through the connecting hose 32, and finally be discharged from the air outlet nozzle 33, blowing the tea leaves at the edge of the storage box 15 to its center, avoiding the phenomenon of blind areas of kneading, and further improving the uniformity of kneading.

[0041] Working principle: Figure 1-9As shown, the tea leaves to be rolled are placed in the storage box 15, and then the height of the movable roller 8 is adjusted according to the amount of tea leaves and the required rolling force. When the movable roller 8 is lowered, the protective pad 6 can be pushed to a convex state to achieve rolling with different forces. In the rolling process, the tea leaves can be dried by the blown gas, and the storage box 15 can be moved horizontally to improve the uniformity of tea leaf distribution.

[0042] At the same time, the repulsion of the magnets is used to generate gas, and the gas is blown toward the tea leaves from the air outlet nozzle 33, which can further improve the uniformity of the distribution of the tea leaves and prevent the tea leaves from piling up at the edge of the storage box 15 and affecting the comprehensiveness of the rolling.

[0043] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein.
