[0015] To solve the above technical problems, the present invention also provides a method for packaging tuo tea, and its innovation lies in: specifically including the following steps:

[0016] (1) Preparation of tuo tea: The tuo tea enters the feeding trough through the feeding device, and moves to the position of the pushing cylinder through the conveyor belt at the straight part where the feeding trough is connected to the feeding device. The pushing cylinder extends to push the tuo tea to be packaged to the position directly above the feeding cylinder in the feeding trough. Since the tip of the tuo tea sent from the feeding device faces upward, the tip of the tuo tea located directly above the feeding cylinder faces upward at this time;

[0017] (2) Preparation of packaging paper: The lifting cylinder adjusts the height of the paper pushing cylinder according to the thickness of the packaging paper in the paper trough. Start the air compressor, and the vacuum suction cup generates negative pressure between it and the packaging paper by suction, sucking the topmost packaging paper. The paper pushing cylinder extends to push the paper sucking unit to move the packaging paper to directly above the tuo tea prepared in step (1), so that the vacuum suction cup stops sucking and covers the packaging paper on the tuo tea;

[0018] (3) Packaging feeding: The feeding cylinder feeds the tuo tea and the packaging paper covering the tuo tea together from the lower end of the tuo tea into the interior of the packaging unit below, that is, into the tea placing hole of the packaging unit, and is clamped by the snap ring;

[0019] (4) Closing of packaging paper: The motor causes the rotating seat to rotate clockwise by 90 degrees. The closing cylinder extends to squeeze the rotating part, causing the rotating part to rotate counterclockwise. The counterclockwise rotation of the rotating part drives the turntable to rotate counterclockwise. The counterclockwise rotation of the turntable causes the closing parts in each chute to move relatively clockwise to the middle position of each corresponding chute, so that the closing parts close, and the periphery of the packaging paper closes towards the center of the tuo tea;

[0020] (5) Squeezing of packaging paper: The motor causes the rotating seat to rotate clockwise by 90 degrees again. The opening cylinder shortens and squeezes the rotating part clockwise. The clockwise rotation of the rotating part drives the turntable to rotate clockwise. The clockwise rotation of the turntable causes the closing parts in each chute to move relatively counterclockwise towards the edge of the chute, so that each closing part slides to open the tea placing hole. The squeezing cylinder extends to squeeze the closed packaging paper downward, squeezing the packaging paper into the concave part of the tuo tea to complete the packaging;

[0021] (6) Packaging and discharging: The motor causes the rotating seat to continue to rotate clockwise by 90 degrees. The discharging cylinder extends towards the receiving device, so that the end of the discharging moving part extends into the tea placement hole inside the packaging unit of the corresponding receiving device, and pushes the well-packaged tuo tea inside the packaging unit into the receiving device. After discharging, the packaging unit rotates clockwise and moves above the feeding unit.

[0022] (7) Repeat steps (1)-(6) to continuously complete the packaging of tuo tea.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] (1) The cooperative use of the packaging base, driving box, feeding mechanism, paper feeding mechanism, rotary packaging mechanism, telescopic packaging mechanism, discharging mechanism and receiving device provided in the tuo tea packaging machine of the present invention can complete the packaging of the handleless mushroom-shaped structure of tuo tea through a simple and convenient packaging structure, and the cooperation degree between each component is relatively high, making the overall packaging efficiency of the packaging machine of the present invention relatively high.

[0025] (2) The packaging unit of the tuo tea packaging machine of the present invention is provided with a housing, a chassis, several snap rings, a rotating part, a turntable and six closing parts. The feeding mechanism sends the tuo tea and the packaging paper into the tea placement hole through the opening of the housing and fixes them with several snap rings. After the rotating seat rotates clockwise by 90 degrees, the closing cylinder moves downward to squeeze the rotating part to rotate counterclockwise, driving the turntable to rotate counterclockwise, so that each closing part moves clockwise to the middle of the chute to close the opening of the turntable. At the same time, it drives the periphery of the packaging paper to close towards the concave part of the tuo tea. After the rotating seat rotates clockwise by 90 degrees again, the extrusion block on it squeezes the rotating part to rotate clockwise through the opening cylinder, driving the closing part to move and open the tea placement hole, and then squeezing the closed packaging paper into the concave part of the tuo tea through the extrusion cylinder to complete the packaging. The structure of the packaging unit is relatively flexible, playing a fast, convenient and relatively good packaging role in the process of closing and squeezing the packaging paper.

[0026] (3) In the tuo tea packaging method of the present invention, the tuo tea conveyed into the packaging machine is sent to the upper end of the feeding cylinder through the feeding mechanism, and then the packaging paper is sent to the top of the tuo tea through the paper feeding mechanism. The feeding cylinder pushes the tuo tea and the packaging paper into the packaging unit. The rotary packaging mechanism rotates the packaging unit and sequentially rotates to four positions clockwise according to the attached drawings shown in the present invention. Then, in cooperation with the telescopic packaging mechanism, the packaging paper is sequentially closed, squeezed, and the packaged tuo tea is pushed out onto the receiving device. The whole packaging process can achieve a relatively high packaging qualification rate in a relatively short time. Brief Description of the Drawings

It also includes a drive box 2, a feeding mechanism, a paper feeding mechanism, a rotary packaging mechanism, a telescopic packaging mechanism, a discharging mechanism, and a material receiving device 3. The drive box, the feeding mechanism, the paper feeding mechanism, and the discharging mechanism are all arranged on the upper surface of the packaging base. The rotary packaging mechanism and the telescopic packaging mechanism are both arranged on the drive box. A motor 4 is arranged inside the drive box. The rotary packaging mechanism is rotationally connected to the motor, and the rotary packaging mechanism is controlled by the motor to perform packaging during rotation. The telescopic packaging mechanism is located above the rotary packaging mechanism, and the telescopic packaging mechanism and the rotary packaging mechanism cooperate to perform the packaging of tuo tea. The feeding mechanism is located in front of the drive box and below the rotary packaging mechanism. The rotary packaging mechanism is used to specifically package the tuo tea and the wrapping paper fed by the feeding mechanism.

[0042] The paper feeding mechanism is located on one side of the feeding mechanism and is used to send the wrapping paper above the tuo tea to be fed into the rotary wrapping mechanism. The discharging mechanism is located on the other side of the feeding mechanism and extends into the rotary wrapping mechanism, and is used to push the wrapped tuo tea into the receiving device. The receiving device is arranged on the side of the packaging base and can receive the materials coming out of the rotary wrapping mechanism.

[0043] The feeding mechanism of a tuo tea packaging machine of the present invention includes a pushing cylinder 5, a feeding cylinder 6 and a feeding chute 7. The feeding chute is an L-shaped feeding chute. One end of the feeding chute is connected to the feeding device outside the packaging base, and the other end is located below the rotary wrapping mechanism. As Figure 1 and 2 shown, the part where the feeding chute communicates with the feeding device is located at the front end of the upper surface of the packaging base, and is used to sequentially convey the tuo tea conveyed by the feeding device 9 to the rotary wrapping mechanism in sequence. A conveyor belt is provided at the bottom of the straight part of the feeding chute connecting the feeding device. Since the conveyor belt is a well-known technology, the solution of the present invention will not be elaborated here. The feeding cylinder is arranged in the packaging base below the rotary wrapping mechanism, and the upper end of the telescopic part of the feeding cylinder penetrates through the packaging base and is connected to the feeding chute, and can push the tuo tea upward into the rotary wrapping mechanism during use. The pushing cylinder is fixed on the packaging base through a cylinder base 8 and is on the same straight line as the part of the feeding chute below the rotary wrapping mechanism. When the tuo tea is conveyed to the right angle of the feeding chute through the conveyor belt, the pushing cylinder extends to push the tuo tea to the upper end part of the feeding cylinder.

[0044] The paper feeding mechanism of a tuo tea packaging machine of the present invention includes a cylinder frame 10, a lifting cylinder 11, a paper pushing cylinder 12, two slide rails 13, a lifting member 14, a lifting connecting member 15, an air compressor 16 and a paper suction unit 17; the cylinder frame is in an inverted U shape and is fixed on the packaging base; a paper chute 18 is arranged on the packaging base between the cylinder frame and the part of the feeding chute below the rotary wrapping mechanism, and wrapping paper 19 is placed in the paper chute; slide rails are arranged on the side of the cylinder frame close to the paper chute, and the lifting member is slidably sleeved on the slide rails; the lifting connecting member is in an L shape, the upper end of the vertical part of the lifting connecting member is connected to the lifting member, the lower surface of the horizontal part is connected to the paper pushing cylinder, and the upper surface of the horizontal part is connected to the lower end of the telescopic part of the lifting cylinder, and the upper end of the lifting cylinder is arranged on the horizontal part of the cylinder frame; the telescopic end of the paper pushing cylinder is connected to the paper suction unit, the paper suction unit is located above the paper chute, and the air compressor is arranged on the packaging base. In the present invention, the functions of the cylinder frame, the slide rails, the lifting member and the lifting connecting member are, on the one hand, to share the load of the paper pushing cylinder and the paper suction unit, so that the whole structure is more stable when working, and on the other hand, to adjust the height of the paper suction unit when the thickness of the wrapping paper changes, so as to accurately suck up the wrapping paper and then transfer it above the tuo tea to be packaged.

[0045] Preferably, the paper suction unit of the present invention includes four vacuum suction cups 20, two limiting members 21, a limiting connecting member 22 and a paper suction connecting member 23, as Figure 3As shown, four vacuum suction cups are arranged in a rectangle on the same plane. A limiting block 24 is provided above the vacuum suction cups. Two limiting members are arranged in parallel and are respectively sleeved in a limiting manner under the limiting blocks of the two vacuum suction cups on the corresponding sides; a limiting connecting member connects the two limiting members; the paper suction connecting member is L-shaped, the horizontal part of the paper suction connecting member is connected to the limiting connecting member, and the vertical part is fixedly connected to the telescopic end of the paper pushing cylinder; the vacuum suction cups are communicated with an air compressor through an air pipe 25. When the paper pushing cylinder acts, the packaging paper sucked by the vacuum suction cups can be just sent to the top of the feeding cylinder above the tuo tea to be packaged, so that when the feeding cylinder pushes the tuo tea upward into the internal rotating packaging mechanism, the packaging paper is pushed in together.

[0046] The rotating packaging mechanism of a tuo tea packaging machine of the present invention includes a rotating rod 26, a rotating seat 27 and four packaging units 28; the rotating seat is cube-shaped and is located directly above the feeding cylinder. The center of the rotating seat and the motor are on the same straight line. One end of the rotating rod is connected to one surface of the rotating seat, and the other end is rotatably connected to the motor; the four packaging units are respectively arranged on the four surfaces adjacent to the surface of the rotating seat connected to the motor; the rotating seat is hollow and the side surface far from the motor is open. The rotating seat of the present invention rotates clockwise, and the rotation angle each time is 90 degrees. The tuo tea enters the lower packaging unit through the feeding mechanism, and then through the clockwise rotation of the rotating seat, the actions of closing the packaging paper, squeezing the packaging paper, and pushing out the tuo tea are carried out in sequence.

[0047] Preferably, each packaging unit of the present invention includes a housing 29, a chassis 30, several snap rings 31, a rotating member 32, a turntable 33, and six closing members 34; the chassis, snap rings, rotating member, turntable, and six closing members are all placed inside the housing. As Figures 4 - 6 shown, circular openings with the same aperture are provided at the center positions of the chassis, turntable, and housing. The openings provided on the chassis, turntable, and housing form a tea placing hole 35 that penetrates the entire packaging unit. When the four packaging units are respectively rotated to the lower part, the tea placing hole is located directly above the feeding cylinder. An extension member 36 extends upward from the edge of the opening of the chassis; each snap ring includes a curved panel 37 that matches the inner side surface of the opening of the chassis and two snap blocks 38 provided on the upper and lower parts of the curved panel. As Figure 7 shown, several snap rings are evenly arranged along the inner side surface of the opening of the chassis, and the two snap blocks are respectively stuck to the bottom of the chassis and the upper edge of the extension member. Preferably, the number of snap rings for feeding in the embodiment of the present invention is three; the turntable is hollow and has an opening at the lower part, and the lower end of the turntable is placed on the upper surface of the extension member; one end of the rotating member penetrates the turntable and extends into the turntable and is fixed to the extension member through a spring 40, and the other end extends outward; the installation position of the rotating member on the packaging unit is: when the packaging unit rotates to below the closing cylinder, the rotating member is located directly below the closing cylinder.

[0048] Six chutes 41 are evenly provided on the periphery of the upper surface of the turntable of the present invention. As Figure 9As shown, each chute is connected to the edge of the turntable. Each chute intersects with the chutes on its adjacent two sides, and the six chutes together form a regular hexagon. Each closing member is fan-shaped. Preferably, the fan shape of the present invention is specifically as Figure 8 shown. A convex block 39 corresponding to the chute is provided at the lower end of the closing member. The convex block is clamped in the chute. When each closing member is at the middle position of the chute, the six closing members can completely block the opening connecting the outer shell and the disc. A rotating clamping member 42 is provided on each closing member, and six clamping grooves 43 are respectively provided on the outer shell at positions corresponding to the six rotating clamping members 42. The six rotating clamping members are correspondingly clamped in the clamping grooves. The clamping grooves can limit the movement of the closing member, ensuring that when the rotating member drives the turntable to move back and forth, the distance that the closing member moves back and forth will not exceed the limited distance, so as to avoid the use of the closing member exceeding the operable range and affecting the packaging of the tuo tea. As Figure 8 and Figure 10 shown, Figure 10 is the state of the closing member when the tuo tea enters the installation unit. When the rotating seat rotates clockwise by 90 degrees, the closing cylinder squeezes the rotating member downward. The rotating member drives the turntable to rotate counterclockwise, so that the closing members inside each chute move clockwise to the middle position of the chute, and the periphery of the packaging paper is inwardly closed. The closed state is as Figure 8 shown.

[0049] The telescopic packaging mechanism of a tuo tea packaging machine of the present invention includes a cross-shaped telescopic connecting member 44, an opening cylinder 45, a closing cylinder 46 and a pressing cylinder 47.

One end of one straight line of the telescopic connecting member is fixed on the driving box, and a pressing cylinder is provided on the other end surface. The pressing cylinder and the tea placing hole of the packaging unit below it are on the same straight line. During use, the pressing cylinder extends downward to squeeze the closed packaging paper into the concave part of the tuo tea. On the other straight line of the telescopic connecting member, an opening cylinder and a closing cylinder are respectively provided at both ends. The closing cylinder is vertically arranged at one end far from the material receiving device, and the closing cylinder is directly above the rotating member of the packaging unit below it. The end of the telescopic connecting member connecting the opening cylinder extends downward to form an opening connecting member 48. The opening cylinder is horizontally arranged on the opening connecting member. Pressing blocks 49 are provided at the telescopic ends of both the opening cylinder and the closing cylinder. The pressing block on the opening cylinder is located on the side of the rotating member of the upper packaging unit close to the closing cylinder. Before the pressing cylinder acts, it is necessary to contract the opening cylinder, move the rotating member clockwise, drive the turntable to move clockwise, and indirectly make the closing member move counterclockwise inside the chute to open the tea placing hole, and then squeeze the packaging paper for packaging through the pressing cylinder.

[0050] The discharging mechanism of a tuo tea packaging machine of the present invention includes a discharging connecting member 50, a discharging cylinder 51 and a discharging moving member 52; the discharging connecting member is arranged at a position on the packaging base close to the material receiving device, the discharging cylinder is arranged at the upper end of the discharging connecting member, the discharging moving member is L-shaped and extends into the rotating seat, the telescopic rod of the discharging cylinder is fixed on the discharging moving member, and the linear direction of the discharging moving member controlled by the discharging cylinder to move is on the same straight line as the tea placing hole of the packaging unit close to the material receiving device. So that through the telescopic movement of the discharging cylinder, the packaged tuo tea inside the packaging unit is pushed into the material receiving device.

[0051] Preferably, the present invention further includes a control console 53, which is arranged on the packaging base and is communicatively connected to the driving box, the feeding mechanism, the paper feeding mechanism, the rotary packaging mechanism, the telescopic packaging mechanism and the discharging mechanism respectively.

[0052] The present invention also provides a method for packaging tuo tea, which specifically includes the following steps:

[0053] (1) Preparation of tuo tea: The tuo tea enters the feeding trough through the feeding device, moves to the position of the pushing cylinder through the conveyor belt at the linear part where the feeding trough is connected to the feeding device, and the pushing cylinder extends to push the tuo tea to be packaged to the position directly above the feeding cylinder in the feeding trough. Since the tip of the tuo tea fed from the feeding device faces upward, the tip of the tuo tea located directly above the feeding cylinder faces upward at this time;

[0054] (2) Preparation of packaging paper: The lifting cylinder adjusts the height of the paper pushing cylinder according to the thickness of the packaging paper in the paper trough, starts the air compressor, and the vacuum suction cup generates negative pressure between it and the packaging paper by suction, sucks the topmost packaging paper, and the paper pushing cylinder extends to push the paper suction unit to move the packaging paper to directly above the tuo tea prepared in step (1), so that the vacuum suction cup stops sucking and covers the packaging paper on the tuo tea;

[0055] (3) Packaging feeding: The feeding cylinder feeds the tuo tea and the packaging paper covering the tuo tea together from the lower end of the tuo tea into the interior of the packaging unit below, that is, into the tea placing hole of the packaging unit, and is clamped by the snap ring;

[0056] (4) Closing of the packaging paper: The motor makes the rotating seat rotate clockwise by 90 degrees, the closing cylinder extends to squeeze the rotating member, so that the rotating member rotates counterclockwise, the counterclockwise rotation of the rotating member drives the turntable to rotate counterclockwise, and the counterclockwise rotation of the turntable makes the closing members in each chute move relatively clockwise to the middle position of each corresponding chute, so that the closing members are closed, and the periphery of the packaging paper is closed towards the center of the tuo tea;

[0057] (5)Wrapping paper extrusion: The motor causes the rotating seat to rotate clockwise by 90 degrees. The opening cylinder shortens and squeezes the rotating part clockwise. The clockwise rotation of the rotating part drives the turntable to rotate clockwise. The clockwise rotation of the turntable causes the closing parts inside each chute to move counterclockwise relative to the sides of the chute, so that each closing part slides open the tea placement hole. The extrusion cylinder extends and squeezes the closed wrapping paper downward, squeezing the wrapping paper into the concave part of the tuo tea to complete the packaging;

7. A method for packing tuo tea, characterized in that: Specifically, it includes the following steps: (1)Tuocha preparation: The tuocha enters the feeding trough through the feeding device. It moves to the position of the pushing cylinder through the conveyor belt at the straight part where the feeding trough is connected to the feeding device. The pushing cylinder extends to push the tuocha to be packaged to the position directly above the feeding cylinder in the feeding trough. Since the tip of the tuocha fed from the feeding device is upward, the tip of the tuocha at this time, which is directly above the feeding cylinder, is upward. (2)Packaging paper preparation: The lifting cylinder adjusts the height of the paper-pushing cylinder according to the thickness of the packaging paper in the paper trough. The air compressor is started. The vacuum suction cup creates a negative pressure between it and the packaging paper by sucking air, sucking the topmost packaging paper. The paper-pushing cylinder extends to push the paper-sucking unit to move the packaging paper to directly above the tuocha prepared in step (1). The vacuum suction cup stops sucking air, covering the packaging paper on the tuocha. (3)Packaging feeding: The feeding cylinder feeds the tuocha and the packaging paper covering the tuocha together from the lower end of the tuocha into the packaging unit below, that is, into the tea-placement hole of the packaging unit, and is clamped by the snap ring. (4)Closing of the packaging paper: The motor causes the rotating seat to rotate 90 degrees clockwise. The closing cylinder extends to squeeze the rotating part, causing the rotating part to rotate counterclockwise. The counterclockwise rotation of the rotating part drives the turntable to rotate counterclockwise. The counterclockwise rotation of the turntable makes the closing parts in each chute move relatively clockwise to the middle position of each corresponding chute, and the closing parts close, closing the periphery of the packaging paper towards the center of the tuocha. (5)Squeezing of the packaging paper: The motor causes the rotating seat to rotate another 90 degrees clockwise. The opening cylinder shortens and squeezes the rotating part clockwise. The clockwise rotation of the rotating part drives the turntable to rotate clockwise. The clockwise rotation of the turntable makes the closing parts in each chute move relatively counterclockwise towards the sides of the chutes, causing each closing part to slide open the tea-placement hole. The squeezing cylinder extends to squeeze the closed packaging paper downward, squeezing the packaging paper into the concave part of the tuocha to complete the packaging. (6)Packaging discharging: The motor causes the rotating seat to continue rotating 90 degrees clockwise. The discharging cylinder extends towards the placement of the receiving device, causing the end of the discharging moving part to extend into the opening inside the packaging unit of the corresponding receiving device, pushing the packaged tuocha inside the packaging unit out into the receiving device. After discharging, the packaging unit rotates clockwise and moves to directly above the feeding unit. (7)Repeat steps (1)-(6) to continuously complete the packaging of tuocha.
