Description

Technical Field

[0001] The invention relates to the technical field of tea processing machinery, and in particular to an automatic tea wrapping and kneading machine and an automatic tea wrapping and kneading method. Background Art

[0002] The production of tea requires many processes to complete, among which the wrapping and kneading process is a crucial link in the tea production process, and this process has a crucial impact on the quality of tea production. At present, many processes in my country's tea production process still rely on manual production or manual and mechanical semi-automatic production. The efficiency of the production process is greatly limited by the scarce labor resources, and the quality of tea production also depends to a large extent on the manual skills of the production master. Therefore, the mechanization and automation of the tea wrapping and kneading process is imperative.

[0003] The traditional tea bagging and kneading process has been accumulated and passed down for many years. In recent years, with the development of science and technology, the research on the automation of the tea bagging and kneading process is conducive to the large-scale quantitative production of enterprises, which not only alleviates the labor shortage, but also significantly reduces the production cost of tea and improves the quality of tea making.

[0004] The wrapping and kneading in the tea making process is commonly known as "ball tea". The function of wrapping and kneading is to make the leaf-shaped tea leaves curl into particles. At present, the more commonly used method is to wrap the tea leaves in a square cotton towel, pinch the mouth of the cotton towel by hand, put the cotton towel in the wrapping and kneading machine for extrusion, rotation and kneading for a certain period of time. During the operation of the wrapping and kneading machine, the mouth of the cotton towel needs to be pinched by hand all the time. The rotation of the wrapping and kneading machine drives the cotton towel to rotate, and the sealing part of the cotton towel is constantly tightened into a twisted rope shape. The tea leaves wrapped in the cotton towel gather into a ball shape. The more the wrapping and kneading machine rotates, the greater the pressure, and the smaller the ball shape of the tea leaves gathered in the cotton towel. After the wrapping and kneading machine drives the cotton towel wrapped in the tea leaves to rotate for a certain period of time, the cotton towel is untied to break up the tea leaves, and the cotton towel is pinched by hand and put into the wrapping and kneading machine again, and it is repeated many times until the tea leaves curl into particles. Although this reduces some labor intensity and improves production efficiency, it requires continuous cooperation between people and machines, and the degree of dependence on manual labor is still relatively large.

[0048] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in combination with the implementation modes and the accompanying drawings.

[0049] Please refer to Figures 1 to 5The present invention provides an automatic tea wrapping and kneading machine, and the specific embodiments are as follows:

[0050] A tea automatic wrapping and kneading machine comprises a left kneading plate 1, a right kneading plate 2, a left kneading motor 3, a right kneading motor 4, a wrapping and kneading drum 5, a hydraulic power push rod assembly 6, a drum seat rotating assembly 7 and a frame 8, wherein the left kneading plate 1 and the right kneading plate 2 are arranged vertically opposite to each other, the left kneading motor 3 is located on the left side of the left kneading plate 1, and its output end is connected to the center of the left kneading plate 1, the right kneading motor 4 is located on the right side of the right kneading plate 2, and its output end is connected to the center of the right kneading plate 2, the wrapping and kneading drum 5 is a cylindrical structure with left and right ends opened, the right kneading plate 2 extends into the right end of the wrapping and kneading drum 5, the hydraulic power push rod assembly 6 drives the left kneading plate 1 to horizontally enter and exit the left end of the wrapping and kneading drum 5, the drum seat rotating assembly 7 drives the wrapping and kneading drum 5 to flip so that the left end can be lifted upward, placed horizontally, and the left end can be tilted downward, and the hydraulic power push rod assembly 6 and the drum seat rotating assembly 7 are fixed on the frame 8.

[0051] When the wrapping and kneading drum 5 is in a horizontal position, the hydraulic power push rod assembly 6 can drive the left kneading plate 1 to enter and exit the wrapping and kneading drum 5. When the left kneading plate 1 extends into the wrapping and kneading drum 5, the left kneading plate 1 cooperates with the right kneading plate 2 to automatically wrap and knead. When the left kneading plate 1 extends out of the wrapping and kneading drum 5, the left end of the wrapping and kneading drum 5 can be lifted up to receive tea leaves or tilted downward to pour out tea leaves. The hydraulic power push rod assembly 6 can not only drive the left kneading plate 1 into the wrapping and kneading drum 5, but also has a certain squeezing effect on the tea leaves in the wrapping and kneading drum 5, so that the wrapped and kneaded tea leaves can be kneaded and formed faster and taste good. The left wrapping and kneading motor 3 drives the left kneading plate 1 to rotate, and the right wrapping and kneading motor 4 drives the right kneading plate 2 to rotate, so that the movements of the left kneading plate 1 and the right kneading plate 2 do not interfere with each other.

[0052] Specifically, the outer diameter of the left kneading plate 1 is the same as that of the right kneading plate 2, and both are matched with the inner diameter of the wrapping and kneading drum 5, preferably with clearance, to prevent the tea leaves from running between the left kneading plate 1 and the wrapping and kneading drum 5 or between the right kneading plate 2 and the wrapping and kneading drum 5.

[0053] Furthermore, the hydraulic power push rod assembly 6 includes a hydraulic cylinder 61, a horizontal linear guide assembly 62 and an inverted L-shaped frame 63. The cylinder body of the hydraulic cylinder 61 is fixed on the slider of the horizontal linear guide assembly 62, the piston rod end of the hydraulic cylinder 61 is fixed on the frame 8, the guide rail of the horizontal linear guide assembly 62 is fixed on the frame 8, the bottom end of the vertical frame of the inverted L-shaped frame 63 is fixed on the slider of the horizontal linear guide assembly 62, and the left wrapping and kneading motor 3 is fixed in the right end of the horizontal frame of the inverted L-shaped frame 63. The guide rail and the slider sliding against each other in the horizontal linear guide assembly 62 guide the left and right telescopic movement of the hydraulic cylinder 61. The left and right telescopic movement of the hydraulic cylinder 61 drives the inverted L-shaped frame 63 to slide left and right, thereby driving the left wrapping and kneading motor 3 and the left kneading plate 1 to slide left and right, and the left kneading plate 1 can extend into or out of the wrapping and kneading drum 5.

[0054] Regardless of whether the piston rod end of the hydraulic cylinder 61 is fixed on the frame 8 and the cylinder body of the hydraulic cylinder 61 is fixed on the slider, or the cylinder body of the hydraulic cylinder 61 is fixed on the frame 8 and the piston rod of the hydraulic cylinder 61 is fixed on the slider, the functions are the same, which is to provide power for the left and right sliding of the inverted L-shaped frame 63.

[0055] Specifically, the left wrapping and kneading motor 3 is located inside the right end of the horizontal frame of the inverted L-shaped frame 63, and the right end of the horizontal frame of the inverted L-shaped frame 63 is placed as a whole within the horizontal extension size range of the outer diameter of the left kneading plate 1, so that the distance between the left wrapping and kneading motor 3 and the left kneading plate 1 is relatively close. When the left kneading plate 1 enters the wrapping and kneading drum 5, a part of the left wrapping and kneading motor 3 and a part of the right end of the horizontal frame of the inverted L-shaped frame 63 can also enter the wrapping and kneading drum 5. The horizontal frame is wide and stable, so that the structure of the entire automatic wrapping and kneading machine is compact and stable.

[0056] Furthermore, the hydraulic power push rod assembly 6 also includes a pressure detection sensor, which is used to detect the pressure of the hydraulic cylinder 61 to prevent the hydraulic cylinder 61 from over-pressuring the tea leaves.

[0057] Furthermore, the roller seat rotating assembly 7 includes a seat frame 71, a bearing seat 72, a connecting rod 73 and an electric push rod 74. The seat frame 71 is fixedly connected to the wrapping and kneading drum 5. The middle part of the seat frame 71 is rotatably connected to the frame 8 through the bearing seat 72. The right end of the seat frame 71 is rotatably connected to one end of the connecting rod 73. The other end of the connecting rod 73 is rotatably connected to the upper end of the electric push rod 74. The lower end of the electric push rod 74 is rotatably connected to the frame 8. The wrapping and kneading drum 5 is fixedly connected to the seat frame 71. The bearing seat 72 realizes the rotational connection between the seat frame 71 and the frame 8, thereby realizing the rotational connection between the wrapping and kneading drum 5 and the frame 8. Specifically, there are two bearing seats 72, which are respectively located at the front and rear sides of the wrapping and kneading drum 5, and the two bearing seats 72 are coaxially arranged. A connecting rod 73 slider mechanism is formed between the electric push rod 74, the connecting rod 73, one end of the connecting rod 73 and the bearing seat 72, and between the bearing seat 72 and the lower end of the electric push rod 74, which can drive the seat frame 71 to swing in the vertical plane, thereby driving the kneading drum 5 to flip in the vertical plane, thereby realizing the action requirements of lifting the left end of the kneading drum 5 upward, placing it horizontally, and tilting the right end downward.

[0058] Preferably, the left end of the wrapping and kneading drum 5 is lifted upward by 45° for receiving the materials, and the left end of the wrapping and kneading drum 5 is tilted downward by 45° for unloading the materials.

[0059] Furthermore, the drum seat rotating assembly 7 also includes a horizontal position detection sensor, which is used to detect whether the wrapping and kneading drum 5 reaches a horizontal position, and the horizontal position detection sensor is installed on the frame 8. The horizontal position detection sensor is installed on the frame 8 to ensure the accuracy of the horizontal placement of the wrapping and kneading drum 5, thereby ensuring that the left kneading plate 1 can smoothly enter the wrapping and kneading drum 5, and ensuring that the left kneading plate 1 does not generate a large friction with the wrapping and kneading drum 5 when rotating.

[0060] Furthermore, it also includes a conveyor belt 9, the feeding end of the conveyor belt 9 is located below the left end of the wrapping and kneading drum 5, and the discharging end of the conveyor belt 9 is located above the left end of the wrapping and kneading drum 5. The feeding end of the conveyor belt 9 can receive the tea leaves poured out from the wrapping and kneading drum 5, and the conveyor belt 9 can transport the tea leaves into the wrapping and kneading drum 5 again, thereby realizing automatic circulation to wrap and knead the tea leaves multiple times.

[0061] Of course, if the tea leaves are transferred from the previous process, they can be directly sent to the conveyor belt 9, whether it is the feeding end of the conveyor belt 9 or the middle of the conveyor belt 9. If the tea leaves are transferred to the next process, the tea leaves in the wrapping and kneading drum 5 can be directly poured onto the connecting piece of the next process, or the tea leaves can be first poured onto the conveyor belt 9 and then transferred to the connecting piece of the next process via the conveyor belt 9. In this way, the automatic wrapping and kneading process of tea leaves can be conveniently connected with the previous process and the next process, so as to realize the automation of tea production. In addition, the conveyor belt 9 can loosen the tea leaves in the process of conveying the tea leaves, so as to facilitate the wrapping and kneading next time.

[0062] Furthermore, the inner side surface of the left kneading plate 1 is evenly distributed with three first step surfaces arranged along the radial direction, and the three first step surfaces are respectively vertically downward, inclined inward, and inclined outward, and the bottom end of each first step surface is uniformly smoothly connected with the top end of the next first step surface along the clockwise or counterclockwise direction to form three first fan-shaped surfaces, and the first fan-shaped surfaces are provided with convex points, and the first step surfaces are straight step surfaces / arc step surfaces. The inner side surface of the right kneading plate 2 is evenly distributed with three second step surfaces arranged along the radial direction, and the three second step surfaces are respectively vertically downward, inclined inward, and inclined outward, and the bottom end of each second step surface is uniformly smoothly connected with the top end of the next second step surface along the clockwise or counterclockwise direction to form three second fan-shaped surfaces, and the second fan-shaped surfaces are provided with convex points, and the second step surfaces are arc step surfaces / straight step surfaces.

[0063] The first step surface on the left kneading plate 1 and the second step surface on the right kneading plate 2 have the function of cutting and kneading the tea leaves. During the kneading process, the tea leaves are squeezed and kneaded inward at a certain angle. During the forward, reverse, and forward and reverse rotation of the left kneading plate 1 and the right kneading plate 2, the tea leaves are squeezed and kneaded in different directions, so that the tea leaves can be rolled up quickly. The convex points on the left kneading plate 1 and the right kneading plate 2 have a stirring effect on the tea leaves in the kneading drum 5, so that the tea leaves in the kneading drum 5 are kneaded more evenly. Under the horizontal thrust of the hydraulic power push rod assembly 6, the left kneading plate 1 also has a squeezing effect on the tea leaves in the kneading drum 5, which is more conducive to the rapid kneading of the tea leaves.

[0064] It also includes a PLC control system, which is electrically connected to the left kneading plate 1 motor, the right kneading plate 2 motor, the pressure detection sensor in the hydraulic power push rod assembly 6, the electric push rod 74 in the roller seat rotating assembly 7, and the horizontal position detection sensor.

[0065] Further, the side wall of the wrapping and kneading drum 5 is provided with ventilation holes arranged in an array. Ventilation holes are arranged in the wrapping and kneading drum 5 to make the air permeability in the wrapping and kneading drum 5 good.

[0066] Please refer to Figures 1 to 5The whole operation process of the above automatic tea wrapping and kneading machine is as follows:

[0067] At the beginning, the left kneading plate 1 is located outside the wrapping and kneading drum 5; the electric push rod 74 contracts downward to drive the wrapping and kneading drum 5 to flip upward, preferably with the left end tilted 45° upward; the conveyor belt 9, the previous process or manual tea is loaded into the wrapping and kneading drum 5, and the electric push rod 74 is pushed upward. When the horizontal position detection sensor detects that the wrapping and kneading drum 5 is in a horizontal position, the electric push rod 74 stops moving; the hydraulic cylinder 61 moves to drive the inverted L-shaped frame 63 to move right as a whole, until the left kneading plate 1 enters the wrapping and kneading drum 5, and the tea in the wrapping and kneading drum 5 is moved. The left kneading motor 3 and the right kneading motor 4 are started, and the left kneading plate 1 and the right kneading plate 2 rotate according to the preset program to automatically knead the tea leaves in the kneading drum 5. After one automatic kneading is completed, the left kneading motor 3 and the right kneading motor 4 stop rotating; the hydraulic cylinder 61 drives the inverted L-shaped frame 63 to move to the left as a whole, and moves the left kneading plate 1 out of the kneading drum 5; the electric push rod 74 pushes up to drive the kneading drum 5 to flip downward, preferably with the left end tilted downward by 45°, and the tea leaves in the kneading drum 5 are poured out, completing one kneading action. If kneading is required again, pour the tea leaves in the kneading drum 5 to the feeding end of the conveyor belt 9; the electric push rod 74 contracts downward to drive the kneading drum 5 to flip upward, preferably with the left end tilted upward by 45°, and the conveyor belt 9 transports the tea leaves to the kneading drum 5, realizing automatic circulation feeding of tea leaves. Of course, the conveyor belt 9 can also be automatically connected to the previous process, and the tea leaves processed in the previous process can be poured onto the conveyor belt 9; the conveyor belt 9 can also be automatically connected to the next process, and the tea leaves conveyed by the conveyor belt 9 can be transported to the connection point of the next process. The automatic tea bagging and kneading machine is initially loaded with leaf-shaped green tea leaves that have been processed by sun drying, killing green tea leaves, and airing green tea leaves. After being kneaded by the automatic tea bagging and kneading machine, the leaf-shaped green tea leaves gradually form a curved spiral shape from leaf shape. When the equipment is initially operated, the required number of tea bagging and kneading times is determined by observing the shape of the tea leaves. After multiple tests, the threshold of the number of tea bagging and kneading times can be pre-set to allow the equipment to work automatically.

[0068] Please refer to Figure 6 The present invention also provides a method for automatically wrapping and kneading tea leaves, and the specific embodiments are as follows:

[0069] A method for automatically wrapping and kneading tea leaves, the operating steps are as follows:

[0070] The S1 drum seat rotating assembly drives the wrapping and kneading drum to flip so that its left end is lifted upwards, and the tea leaves to be rolled are sent into the wrapping and kneading drum;

[0071] The S2 roller seat rotating assembly drives the bag kneading roller to flip and place it horizontally;

[0072] The S3 hydraulic power push rod assembly drives the left kneading plate to extend into the kneading drum and squeeze the tea leaves in the kneading drum; the left kneading motor and the right kneading motor drive the left kneading plate and the right kneading plate to rotate according to the preset steps to knead the tea leaves;

[0073] The S4 hydraulic power push rod assembly drives the left kneading plate to move out of the kneading drum, and the drum seat rotation assembly drives the kneading drum to flip so that its left end tilts downward to pour out the tea leaves in the kneading drum.

[0074] The drum seat rotating assembly can drive the wrapping and kneading drum to do a flipping movement, and the left end of the wrapping and kneading drum is lifted upward, and the tea leaves are loaded into the wrapping and kneading drum. The wrapping and kneading drum is placed horizontally, and the left kneading plate is extended into the wrapping and kneading drum under the drive of the hydraulic power push rod assembly, and has a certain squeezing effect on the tea leaves in the wrapping and kneading drum. The left and right kneading plates rotate according to the preset program to wrap and knead the tea leaves in the wrapping and kneading drum, thereby realizing automatic wrapping and kneading of the tea leaves. After wrapping and kneading, the hydraulic power push rod assembly drives the left kneading plate to leave the wrapping and kneading drum. At this time, the left end of the wrapping and kneading drum tilts downward, and the tea leaves in the wrapping and kneading drum are poured out, completing a wrapping and kneading process.

[0075] For further information, please refer to Figure 7 The automatic tea wrapping and kneading method further comprises:

[0076] The left end of S5 wrapping and kneading drum tilts downward to pour the tea leaves in the wrapping and kneading drum onto the feeding end of the conveyor belt, and the wrapping and kneading times increase by 1;

[0077] S6 queries whether the number of wrapping and kneading times reaches the wrapping and kneading times threshold. If not, the drum mount rotating assembly drives the wrapping and kneading drum to flip so that its left end is lifted upward, and the conveyor belt delivers the tea leaves from the discharge end into the wrapping and kneading drum, and goes to step S2; if yes, the conveyor belt delivers the tea leaves to the next process for use.

[0078] A tea bagging and kneading times threshold is preset. When the tea bagging and kneading times threshold is not reached, the conveyor belt receives the tea leaves in the bagging and kneading drum and conveys the tea leaves again to the bagging and kneading drum lifted upward at the left end for further bagging and kneading. When the tea bagging and kneading times threshold is reached, the tea leaves are automatically bagged and kneaded, and the tea leaves in the bagging and kneading drum are poured onto the conveyor belt and sent to the next process for use, such as the drying process.

[0079] Furthermore, during the automatic wrapping and kneading of the tea leaves,

[0080] Step S3 is specifically as follows:

[0081] The S31 hydraulic power push rod assembly drives the left kneading plate to extend into the kneading drum and squeeze the tea leaves in the kneading drum until the pressure sensor detects that the pressure of the hydraulic cylinder reaches the pressure threshold;

[0082] S32 The left kneading plate and the right kneading plate respectively operate in one of the following steps until the pressure sensor detects that the pressure of the hydraulic cylinder reaches the pressure threshold:

[0083] S321 The left kneading motor drives the left kneading plate to rotate forward, and the right kneading motor drives the right kneading plate to rotate reversely;

[0084] S322 The left kneading motor drives the left kneading plate to rotate forward, while the right kneading motor drives the right kneading plate not to rotate;

[0085] S323 The left kneading motor drives the left kneading plate to rotate forward, and the right kneading motor drives the right kneading plate to rotate forward;

[0086] S324 The left kneading motor drives the left kneading plate to stop rotating, while the right kneading motor drives the right kneading plate to reverse;

[0087] S325 The left kneading motor drives the left kneading plate to stop rotating, while the right kneading motor drives the right kneading plate to rotate forward;

[0088] S326 The left kneading motor drives the left kneading plate to reverse, and the right kneading motor drives the right kneading plate to reverse;

[0089] S327 The left kneading motor drives the left kneading plate to reverse, and the right kneading motor drives the right kneading plate not to rotate;

[0090] S328 The left kneading motor drives the left kneading plate to rotate in reverse, and the right kneading motor drives the right kneading plate to rotate in forward direction;

[0091] S33: the left kneading plate and the right kneading plate respectively operate in a program in the opposite direction of the rotation in step S32 until the pressure sensor detects that the pressure of the hydraulic cylinder reaches the pressure threshold;

[0092] S34: The number of times the hydraulic cylinder stays is increased by 1, and it is detected whether the number of times the hydraulic cylinder stays reaches the threshold value of the number of times. If not, the hydraulic cylinder drives the left kneading plate to move M distance to the left and stays for N seconds, and then goes to step S31; if yes, then goes to step S4.

[0093] When the pressure sensor detects that the pressure of the hydraulic cylinder reaches the pressure threshold, the hydraulic cylinder stops driving the left kneading plate to move to the left to prevent damage to the tea tissue. The left kneading motor drives the left kneading plate to rotate forward and reversely, and the right kneading motor drives the right kneading plate to rotate forward and reversely. The left kneading plate and the right kneading plate rotate in the same direction, in the opposite direction, or only one of them rotates. The left kneading plate squeezes the tea leaves to the left for many times and moves the tea leaves in a variety of different directions in step S33, so that the tea leaves are kneaded and scattered, and the kneading effect is better. In step S33, the left kneading plate and the right kneading plate respectively run according to the program opposite to the rotation direction in step S32, which plays the role of breaking up the tea leaves on the one hand, and plays the role of stirring and reverse kneading on the other hand. In step S34, the hydraulic cylinder drives the left kneading plate to move M distance to the left and stays for N seconds, in order to provide space and time for the tea leaves in the kneading drum to be scattered. After the tea leaves are scattered in the kneading drum, the left kneading plate is transferred to step S31 to continue to move the left kneading plate to squeeze the tea leaves for further kneading.

[0094] In summary, the automatic tea wrapping and kneading method provided by the present invention is:

[0095] The S1 drum seat rotating assembly drives the wrapping and kneading drum to flip so that its left end is lifted upwards, and the tea leaves to be rolled are sent into the wrapping and kneading drum;

[0096] The S2 roller seat rotating assembly drives the bag kneading roller to flip and place it horizontally;

[0097] The S3 hydraulic power push rod assembly drives the left kneading plate to extend into the kneading drum and squeeze the tea leaves in the kneading drum; the left kneading motor and the right kneading motor drive the left kneading plate and the right kneading plate to rotate according to the preset steps to knead the tea leaves; specifically:

[0098] The S31 hydraulic power push rod assembly drives the left kneading plate to extend into the kneading drum and squeeze the tea leaves in the kneading drum until the pressure sensor detects that the pressure of the hydraulic cylinder reaches the pressure threshold;

[0099] S32 The left kneading plate and the right kneading plate respectively operate in one of the following steps until the pressure sensor detects that the pressure of the hydraulic cylinder reaches the pressure threshold:

[0100] S321 The left kneading motor drives the left kneading plate to rotate forward, and the right kneading motor drives the right kneading plate to rotate reversely;

[0101] S322 The left kneading motor drives the left kneading plate to rotate forward, while the right kneading motor drives the right kneading plate not to rotate;

[0102] S323 The left kneading motor drives the left kneading plate to rotate forward, and the right kneading motor drives the right kneading plate to rotate forward;

[0103] S324 The left kneading motor drives the left kneading plate to stop rotating, while the right kneading motor drives the right kneading plate to reverse;

[0104] S325 The left kneading motor drives the left kneading plate to stop rotating, while the right kneading motor drives the right kneading plate to rotate forward;

[0105] S326 The left kneading motor drives the left kneading plate to reverse, and the right kneading motor drives the right kneading plate to reverse;

[0106] S327 The left kneading motor drives the left kneading plate to reverse, and the right kneading motor drives the right kneading plate not to rotate;

[0110] The S4 hydraulic power push rod assembly drives the left kneading plate to move out of the kneading drum, and the drum seat rotating assembly drives the kneading drum to flip so that its left end tilts downward to pour out the tea leaves in the kneading drum;

[0111] The left end of S5 wrapping and kneading drum tilts downward to pour the tea leaves in the wrapping and kneading drum onto the feeding end of the conveyor belt, and the wrapping and kneading times increase by 1;

[0112] S6 queries whether the number of wrapping and kneading times reaches the wrapping and kneading times threshold. If not, the drum mount rotating assembly drives the wrapping and kneading drum to flip so that its left end is lifted upward, and the conveyor belt delivers the tea leaves from the discharge end into the wrapping and kneading drum, and goes to step S2; if yes, the conveyor belt delivers the tea leaves to the next process for use.
