Description

Technical Field

[0001] This invention relates to the field of capsule tea production technology, and in particular to an automatic packaging device for Dragon Pearl capsule tea. Background Technology

[0002] Capsule packaging is a manufacturing process that involves filling tea powder or granules into capsule shells. This packaging method offers many advantages, such as ease of carrying and storage, protection of tea from environmental factors like oxygen, sunlight, and moisture, extended shelf life, and improved taste and quality. Existing capsule packaging equipment primarily employs a production line approach, completing the filling and packaging of tea capsules through a continuous process. This equipment typically arranges capsule shells at the bottom of the packaging unit, then uses robotic arms or automated equipment to fill the capsule shells with the filler material, and finally seals them.

[0003] Dragon ball tea is a common type of tea on the market, characterized by its large, spherical tea leaves. It boasts a unique taste and health benefits, making it popular among consumers. Most commercially available tea capsules contain tea dust, dregs, or powder; there's a lack of products that encapsulate dragon ball tea, indicating a promising market potential. However, current capsule packaging technology can only handle tea dust, dregs, or powder, not dragon ball tea. Therefore, the market lacks products that encapsulate dragon ball tea in capsules. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic packaging device for Dragon Pearl Tea capsules, which is suitable for packaging Dragon Pearl Tea into capsules, laying a foundation for expanding the market for Dragon Pearl Tea capsules.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0006] An automatic packaging device for dragon pearl capsule tea includes a frame, within which two opposing chains are movably arranged. A drive motor for driving the chains is installed within the frame. The two chains are connected to multiple support blocks distributed along their length. Each support block has a cup groove that conforms to the shape of a capsule cup. An automatic cup dropping device, an automatic feeding device, an automatic film feeding device, an automatic sealing device, and an automatic material picking device are sequentially arranged on the frame along the length of the chains.

[0007] The automatic cup-dispensing device includes a cup-dispensing rack connected to the frame and located above the support block, with an open lower end. The upper end of the cup-dispensing rack has a cup-dispensing opening corresponding to the cup slot. A cup-storage rack is provided on the upper end of the cup-dispensing rack around the outer periphery of the cup-dispensing opening. At least two arc-shaped cup-guide strips are provided downwards along the edge of the cup-dispensing opening. An arc-shaped protruding support strip is provided on the inner side of each arc-shaped cup-guide strip. At least two electromagnets are installed on the support frame at the edge of the cup-dispensing opening. Each electromagnet is directly opposite the gap between the two arc-shaped cup-guide strips. A baffle is provided below each electromagnet on the cup-dispensing rack, and each baffle has an upward-facing... The vertical sliding shaft connected to the cup holder has a sliding iron plate movably installed at the upper end of each baffle. Each sliding iron plate has a sliding hole that is slidably connected to the corresponding vertical sliding shaft. Each vertical sliding shaft is fitted with a vertical spring located between the cup holder and the corresponding sliding iron plate. Each sliding iron plate has a pull-down plate at its upper end. The tip of the pull-down plate can extend into the gap between two arc-shaped guide cup strips. The cup holder has at least two guide strips that cooperate with the pull-down plate on the outer periphery of the cup opening. Each guide strip can allow the corresponding pull-down plate to rise to its highest point and then extend into the gap between the two arc-shaped guide cup strips and maintain the extended state as it descends.

[0008] The automatic feeding device includes a feeding hopper disposed on one side above the frame. A rotating disk is horizontally rotatably connected to the bottom of the feeding hopper. A rotating motor for driving the rotating disk to rotate is installed at the lower end of the feeding hopper. A conical guide platform is provided upward in the middle of the rotating disk. Multiple circularly distributed feeding ports are opened downward on the edge of the conical guide platform on the rotating disk. A discharge port corresponding to the feeding ports is opened directly above the cup groove of the feeding hopper.

[0009] The automatic film feeding device includes an inverted L-shaped film feeding frame disposed on one side of the upper end of the frame. The upper end of the inverted L-shaped film feeding frame has a lower film opening corresponding to the position of the cup groove. Multiple arc-shaped protrusions are provided on the inner side of the lower film opening. A film storage frame is provided on the upper end of the inverted L-shaped film feeding frame at the outer periphery of the lower film opening. A horizontal reciprocating motor is installed on the side of the inverted L-shaped film feeding frame that is horizontally facing the support block. A telescopic negative pressure suction device is installed on the power output shaft of the horizontal reciprocating motor. The operating end of the telescopic negative pressure suction device can move vertically back and forth at the opening of the lower film opening and the cup groove.

[0010] The automatic sealing device includes an inverted L-shaped sealing frame disposed on one side of the upper end of the frame. A downwardly oriented vertical telescopic motor is installed at the upper end of the inverted L-shaped sealing frame. The telescopic shaft at the lower end of the vertical telescopic motor is connected to an electric heating sealing ring that cooperates with the cup groove.

[0011] The automatic feeding device includes a vertical reciprocating motor installed on one side of the upper end of the frame and a telescopic negative pressure suction device installed on the power output shaft of the vertical reciprocating motor. The telescopic negative pressure suction device is capable of horizontal reciprocating motion and its operating end cooperates with the cup slot.

[0012] When using the above technical solution to package Dragon Pearl Tea capsules, the following steps are performed:

[0013] 1. When the electromagnet is energized, it attracts the sliding iron piece to move upward. When it reaches the highest position, the guide shaft of the pull-down piece enters the vertical guide groove from the inlet. The tip of the pull-down piece is inserted between the mouths of the two capsule cups at the bottom of the cup holder. Finally, the electromagnet is de-energized. Under the action of the vertical spring, the sliding iron piece and the pull-down piece are pushed downward. The guide shaft moves downward along the vertical guide groove, pushing the bottom capsule cup downward. The edge of the capsule cup undergoes elastic deformation and comes off the arc-shaped protruding support strip, eventually falling into the cup groove of the support block. Then the electromagnet is energized again. At this time, when the guide shaft moves upward, it is blocked by the stop bar and cannot enter the vertical guide groove. It can only move upward along the outside of the elastic bar. At this time, the pull-down piece moves outward, so that the pull-down piece moves upward to the top and then inserts inward between the mouths of the two capsule cups at the bottom of the cup holder, pushing the bottom capsule cup downward. Then it withdraws outward and continues to move upward.

[0014] Second, when the support block moves to the automatic feeding device, it is directly opposite the feeding port of the feeding bucket. A sorting port is also directly opposite the feeding port, and a piece of dragon ball tea falls into the cup groove of the support block. Then the support block continues to move.

[0015] 3. When the support block moves to the automatic film feeding device and is directly facing the lower film opening, the telescopic negative pressure suction device lifts up to suck up an aluminum film from the lower film opening, rotates down to place the aluminum film on the capsule cup opening in the cup slot, and then the support block continues to move.

[0016] 4. When the support block moves directly below the automatic sealing device, the vertical telescopic motor extends, causing the heating sealing ring to descend and contact the aluminum film in the cup groove. It continues to extend, increasing the pressure of the heating sealing ring on the aluminum film. At the same time, the heating sealing ring heats up, causing the aluminum film to stick to the opening of the capsule cup under heat and pressure. Then the support block continues to move.

[0017] 5. When the support block moves directly under the automatic feeding device, the horizontal reciprocating motor drives the telescopic negative pressure suction device to rotate and face the capsule tea. The electric telescopic rod of the telescopic negative pressure suction device extends, so that its suction cup picks up the capsule tea. Finally, the electric telescopic rod shortens and rotates back to remove the capsule tea from the cup slot and place it in the collection box.

[0018] A further provision of the present invention includes an automatic inflation device located between the automatic feeding device and the automatic film feeding device. The automatic inflation device includes an inverted L-shaped inflation frame disposed on one side of the upper end of the frame, a nitrogen tank, an inflation nozzle disposed at the lower end of the inverted L-shaped inflation frame and corresponding to the position of the cup slot, and a solenoid valve disposed at the upper end of the inverted L-shaped inflation frame and communicating with the inflation nozzle. The outlet end of the nitrogen tank is connected to the solenoid valve through an inflation pipe.

[0019] By adopting the above technical solution, when the support block moves to the automatic inflation device and is located directly below the inflation nozzle, the solenoid valve opens and injects nitrogen into the capsule cup, which can effectively extend the shelf life of the capsule tea.

[0020] A further feature of the present invention is that: each pull tab is slidably connected to the upper end of a corresponding sliding iron piece; each sliding iron piece has two sliding sleeves at its upper end; each sliding iron piece has a horizontal sliding shaft slidably connected to the sliding sleeve at its end away from the cup opening; each horizontal sliding shaft is fitted with a horizontal spring disposed between the corresponding pull tab and the corresponding sliding sleeve; each pull tab has guide shafts arranged outward on both sides; each guide bar includes a vertical bar and an elastic bar; each vertical bar and its corresponding elastic bar form a vertical guide groove; the upper sidewall of each elastic bar is connected to the corresponding vertical bar; each elastic bar has an inlet communicating with the corresponding vertical guide groove at its upper end; and each elastic bar has a stop bar inclined downward at its lower end, facing the corresponding vertical bar, the stop bar being used to prevent the guide shaft from entering the vertical guide groove upward.

[0021] A further feature of the present invention is that a limiting strip corresponding to each of the sliding iron pieces is provided at the top of the cup holder. When the sliding iron pieces move upward and contact the limiting strips, the guide shaft can enter the vertical guide groove from the inlet.

[0022] A further configuration of the present invention is as follows: the telescopic negative pressure suction device includes an electric telescopic rod installed on the power output shaft of the horizontal reciprocating motor or the power output shaft of the vertical reciprocating motor, a voice coil motor installed on the free end of the telescopic shaft of the electric telescopic rod, a piston cylinder disposed on the free end of the voice coil motor, and a suction cup disposed on the free end of the piston cylinder and communicating with its interior, wherein the telescopic shaft of the voice coil motor is connected to a negative pressure piston that is slidably connected to the inner wall of the piston cylinder.

[0023] By adopting the above technical solution, the voice coil motor drives the negative pressure piston to move inward, which can generate negative pressure in the suction cup to attract the aluminum film or tea capsules. At the same time, the electric telescopic rod extends and retracts to pick up the aluminum film or tea capsules. The voice coil motor has an extremely fast operating speed, which can quickly and efficiently attract the aluminum film or tea capsules.

[0024] A further configuration of the present invention is as follows: the telescopic shaft at the lower end of the vertical telescopic motor is connected to the electrothermal sealing ring via a buffer. The buffer includes a horizontal fixed plate connected to the telescopic shaft at the lower end of the vertical telescopic motor and a horizontal movable plate disposed below and opposite to the horizontal fixed plate. The electrothermal sealing ring is disposed at the lower end of the horizontal movable plate. The horizontal movable plate is provided with multiple T-shaped sliding shafts facing upward. Multiple sliding connection holes are provided through the horizontal fixed plate and are slidably connected to the T-shaped sliding shafts one by one. Each T-shaped sliding shaft is fitted with a support spring located between the horizontal fixed plate and the horizontal movable plate.

[0025] A further feature of the present invention is that both the cup holder and the film holder are composed of four vertical shafts arranged in a circle.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] Firstly, this invention, through an automatic cup-dropping device, an automatic feeding device, an automatic inflation device, an automatic film-feeding device, an automatic film-sealing device, and an automatic material-retrieving device, can encapsulate dragon pearl tea into capsule cups. It is suitable for the encapsulation of dragon pearl capsule tea, and the encapsulation process is efficient and fast, which helps to lay a good foundation for the market expansion of dragon pearl capsule tea.

[0028] Secondly, this invention adopts a brand-new automatic cup-dropping technology, which uses the on and off power of an electromagnet to achieve automatic cup dropping. When dropping the cup, the capsule cup is pulled downwards and quickly into the cup slot. Compared with the traditional method of automatically dropping the cup by the weight of the capsule cup, the dropping speed is faster, which can effectively save the time spent dropping the cup and can effectively shorten the packaging time of Dragon Pearl Capsule Tea.

[0029] Thirdly, the automatic feeding device of the present invention can automatically feed the Dragon Ball Tea during the rotation of the rotating plate. It does not have a complicated conveying structure, and the feeding speed is fast, which can effectively shorten the packaging time of Dragon Ball Tea capsules. Attached Figure Description

[0038] The present invention will be further described in detail below with reference to the accompanying drawings.

[0039] In the description of this invention, it should be understood that the terms "upper", "lower", "left", "right", "front", "rear", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0040] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0041] Example, refer to Figure 1-7An automatic packaging device for dragon pearl capsule tea includes a frame 1. Two opposing chains 11 are movably arranged inside the frame 1. A drive motor 12 for driving the chains 11 is installed inside the frame 1. The two chains 11 are connected to a plurality of support blocks 13 distributed along their length direction. Each support block 13 has a cup groove 14 that matches the shape of the capsule cup. An automatic cup dropping device, an automatic feeding device, an automatic inflation device, an automatic film feeding device, an automatic sealing device, and an automatic material picking device are arranged sequentially along the length direction of the chains 11 on the frame 1.

[0042] The automatic cup dropping device includes a cup dropping rack 2 connected to the frame 1 and located above the support block 13 with an open bottom. The cup dropping rack 2 is approximately U-shaped with an open bottom. The upper end of the cup dropping rack 2 has a cup dropping opening 21 corresponding to the position of the cup slot 14. The upper end of the cup dropping rack 2 has a cup storage rack 22 arranged upward on the outer periphery of the cup dropping opening 21. The cup storage rack 22 is composed of four vertical shafts arranged in a circle. The edge of the cup dropping opening 21 has two arc-shaped cup guide strips 23 arranged in a front-to-back pattern. There are at least two arc-shaped cup guide strips 23, or more. Each arc-shaped cup guide strip 23 has three arc-shaped protruding support strips 24 on its inner side. The arc-shaped protruding support strips 24 are used to prevent the capsule cup from sliding down.

[0043] Two electromagnets 25 are installed on both the left and right sides of the edge of the cup-dropping opening 21 of the support frame. The number of electromagnets 25 is the same as that of the arc-shaped guide cup strips 23. Each electromagnet 25 is directly opposite the gap between the two arc-shaped guide cup strips 23. A baffle 26 is provided below each electromagnet 25 of the cup-dropping frame 2. A vertical sliding shaft 27 connected to the cup-dropping frame 2 is provided on both the front and back sides of each baffle 26. A sliding iron plate 3 is movably provided at the upper end of each baffle 26. Each sliding iron plate 3 has two sliding holes 31 that are slidably connected to the corresponding vertical sliding shaft 27. Each vertical sliding shaft 27 is fitted with a vertical spring 28 located between the cup-dropping frame 2 and the corresponding sliding iron plate 3. When no external force is applied, the sliding iron plate 3 is in contact with the baffle 26. When the electromagnet 25 is energized, it generates magnetism and attracts the sliding iron plate 3 to move upward. Each sliding iron plate 3 has a pull-down piece 32 at its upper end, and the tip of the pull-down piece 32 can extend into the gap between the two arc-shaped guide cup strips 23.

[0044] Each pull tab 32 is slidably connected to the upper end of the corresponding sliding iron plate 3. Each sliding iron plate 3 has two sliding sleeves 33 at its upper end. Each sliding iron plate 3 has two horizontal sliding shafts 34 slidably connected to the sliding sleeves 33 at the end away from the cup opening 21. Each horizontal sliding shaft 34 is fitted with a horizontal spring 35 between the corresponding pull tab 32 and the corresponding sliding sleeve 33. The horizontal spring 35 drives the pull tab 32 to extend into the two arc-shaped guide cup strips 23. Each pull tab 32 has a guide shaft 36 extending outward on both its front and rear sides. Inside the cup holder 2, around the outer periphery of the cup opening 21, there is a guide bar 4 on both the front and rear sides of each arc-shaped guide bar 23, which cooperates with the pull-down tab 32. Each guide bar 4 includes a vertical bar 41 and an elastic bar 42. Each vertical bar 41 and the corresponding elastic bar 42 form a vertical guide groove 43. The upper sidewall of each elastic bar 42 is connected to the corresponding vertical bar 41. An inlet 44 communicating with the corresponding vertical guide groove 43 is provided at the upper end of each elastic bar 42. A stop bar 45 is inclined downward at the lower end of each elastic bar 42 and faces the corresponding vertical bar 41. 45 is used to prevent the guide shaft 36 from entering the vertical guide groove 43 upwards. After the pull tab 32 moves upwards to its highest position, under the action of the horizontal spring 35, the guide shaft 36 enters the vertical guide groove 43 from the inlet 44. When the pull tab 32 moves downwards from top to bottom, it moves downwards along the vertical guide groove 43 and finally pushes open the stop bar 45, causing the elastic bar 42 to undergo elastic deformation and slide out from the lower end of the vertical guide groove 43. When the pull tab 32 moves upwards from bottom to top, it contacts the stop bar 45, which then blocks the guide shaft 36 from entering the vertical guide groove 43 and allows it to move upwards along the outside of the elastic bar 42. Two limiting bars 29 are provided downwards on the left and right sides of the top of the cup holder 2, corresponding one-to-one with the sliding iron piece 3. When the sliding iron piece 3 moves upwards and contacts the limiting bar 29, the guide shaft 36 can just enter the vertical guide groove 43 from the inlet 44.

[0045] The automatic feeding device includes a feeding hopper 5 located on one side above the frame 1. A rotating disk 51 is horizontally rotatably connected to the bottom of the feeding hopper 5. A rotating motor 52 is installed at the lower end of the feeding hopper 5 to drive the rotating disk 51 to rotate. A conical guide platform 53 is provided upward in the middle of the rotating disk 51. Multiple circularly distributed feeding ports 54 are opened downward on the edge of the conical guide platform 53 on the rotating disk 51. The conical guide platform 53 allows the dragon pearl tea in the feeding hopper 5 to continuously roll into the feeding ports 54. A dropping port 55 corresponding to the feeding port 54 is opened directly above the cup groove 14 of the feeding hopper 5. The rotation speed of the rotating disk 51 is matched with the movement speed of the support block 13. When a support block 13 is facing the dropping port 55, a feeding port 54 is also facing the dropping port 55, and just then a dragon pearl tea falls into the cup groove 14 of the support block 13.

[0046] The automatic inflation device includes an inverted L-shaped inflation frame 6 located on one side of the upper end of the frame 1, a nitrogen tank 61, an inflation nozzle 62 located at the lower end of the inverted L-shaped inflation frame 6 and corresponding to the position of the cup slot 14, and a solenoid valve 63 located at the upper end of the inverted L-shaped inflation frame 6 and connected to the inflation nozzle 62. The outlet end of the nitrogen tank 61 is connected to the solenoid valve 63 through an inflation pipe 64. Whenever the support block 13 is directly below the inflation nozzle 62, the solenoid valve 63 opens to inject nitrogen into the capsule cup, increasing the shelf life of the capsule tea.

[0047] The automatic film feeding device includes an inverted L-shaped film feeding frame 7 located on one side of the upper end of the frame 1. The upper end of the inverted L-shaped film feeding frame 7 has a lower film opening 71 corresponding to the position of the cup groove 14. The inner side of the lower film opening 71 is provided with two arc-shaped protrusions 72. The upper end of the inverted L-shaped film feeding frame 7 is provided with a film storage frame 73 on the outer periphery of the lower film opening 71. The film storage frame 73 is composed of four vertical shafts distributed in a circle. A horizontal reciprocating motor 74 is installed on the side of the inverted L-shaped film feeding frame 7 facing the support block 13. A telescopic negative pressure suction device 8 is installed on the power output shaft of the horizontal reciprocating motor 74. The operating end of the telescopic negative pressure suction device 8 can move vertically back and forth at the opening of the lower film opening 71 and the cup groove 14 to take the aluminum film of the film storage frame 73 from the lower film opening 71 and place it on the capsule cup opening in the cup groove 14.

[0048] The automatic sealing device includes an inverted L-shaped sealing frame 9 located on one side of the upper end of the frame 1. A downward-facing vertical telescopic motor 91 is mounted on the upper end of the inverted L-shaped sealing frame 9. A buffer is connected to the telescopic shaft at the lower end of the vertical telescopic motor 91. The buffer includes a horizontal fixed plate 92 connected to the telescopic shaft at the lower end of the vertical telescopic motor 91, and a horizontal movable plate 93 located below and opposite the horizontal fixed plate 92. Four T-shaped sliding shafts 94 are arranged upwards along the edge of the horizontal movable plate 93, penetrating water... The edge of the flat fixed plate 92 has four sliding connection holes (figure omitted) that correspond one-to-one with the T-shaped sliding shafts 94. Each T-shaped sliding shaft 94 is fitted with a support spring 95 located between the horizontal fixed plate 92 and the horizontal movable plate 93. The lower end of the horizontal movable plate 93 is connected to an electrothermal sealing ring 96 that cooperates with the cup groove 14. The buffer allows the electrothermal sealing ring 96 to gradually press downward instead of pressing it directly into place, preventing the electrothermal sealing ring 96 from heat-sealing the aluminum film and the capsule cup, which would result in a poor seal.

[0049] An automatic feeding device includes a vertical reciprocating motor 10 mounted on one side of the upper end of the frame 1 and a telescopic negative pressure suction device 8 mounted on the power output shaft of the vertical reciprocating motor 10. The telescopic negative pressure suction device 8 can move horizontally back and forth and its operating end cooperates with the cup slot 14. The telescopic negative pressure suction device 8 is used to take the capsule tea on the support block 13 out of the cup slot 14 and put it into the collection frame outside the support.

[0050] The telescopic negative pressure suction device 8 includes an electric telescopic rod 81 mounted on the power output shaft of a horizontal reciprocating motor 74 or a vertical reciprocating motor 10, a voice coil motor 82 mounted on the free end of the telescopic shaft of the electric telescopic rod 81, a piston cylinder 83 located at the free end of the voice coil motor 82, and a suction cup 84 located at the free end of the piston cylinder 83 and communicating with its interior. The telescopic shaft of the voice coil motor 82 is connected to a negative pressure piston 85 that is slidably connected to the inner wall of the piston cylinder 83. When the voice coil motor 82 drives the negative pressure piston 85 to move inward, the suction cup 84 can generate negative pressure, which can attract the aluminum film or capsule tea. The electric telescopic rod 81 extends and retracts to pick up the aluminum film or capsule tea.

[0051] Working principle: When packaging Dragon Pearl Tea capsules, the following steps are performed:

[0052] 1. When electromagnet 25 is energized, it attracts sliding iron plate 3 to move upward. When it reaches the highest position, the guide shaft 36 of pull-down plate 32 enters the vertical guide groove 43 from the inlet 44, so that the tip of pull-down plate 32 is inserted between the gaps of the two capsule cup mouths at the bottom of the cup holder 22. Finally, electromagnet 25 is de-energized, and under the action of vertical spring 28, it pushes sliding iron plate 3 and pull-down plate 32 downward. Guide shaft 36 moves downward along vertical guide groove 43, pushing the bottom capsule cup downward, causing the edge of the capsule cup mouth to... The elastic deformation detaches from the arc-shaped protruding support strip 24 and eventually falls into the cup groove 14 of the support block 13. Then the electromagnet 25 is energized again. At this time, when the guide shaft 36 moves upward, it is blocked by the stop strip 45 and cannot enter the vertical guide groove 43. It can only move upward along the outside of the elastic strip 42. At this time, the pull tab 32 moves outward, so that the pull tab 32 moves upward to the top and then inserts inward into the gap between the two capsule cup mouths at the bottom of the cup holder 22. It pushes the bottom capsule cup downward and then withdraws outward and continues to move upward.

[0053] Second, when the support block 13 moves to the automatic feeding device, it is directly opposite the feeding port 55 of the feeding bucket 5. A sorting port 54 is also directly opposite the feeding port 55. Just then, a piece of dragon pearl tea falls into the cup groove 14 of the support block 13. Then the support block 13 continues to move.

[0054] Third, when the support block 13 moves to the automatic inflation device and is directly below the inflation nozzle 62, the solenoid valve 63 opens to inject nitrogen into the capsule cup, and then the support block 13 continues to move.

[0055] Fourth, when the support block 13 moves to the automatic film feeding device and is directly facing the lower film opening 71, the telescopic negative pressure suction device 8 sucks up an aluminum film from the lower film opening 71 and rotates downward to place the aluminum film on the capsule cup opening in the cup groove 14. Then the support block 13 continues to move.

[0056] 5. When the support block 13 moves directly below the automatic sealing device, the vertical telescopic motor 91 extends, causing the electric heating sealing ring 96 to descend and contact the aluminum film in the cup groove 14. It continues to extend, increasing the pressure of the electric heating sealing ring 96 on the aluminum film. At the same time, the electric heating sealing ring 96 heats up, causing the aluminum film to stick together with the opening of the capsule cup under heat and pressure. Then the support block 13 continues to move.

[0057] 6. When the support block 13 moves directly under the automatic material handling device, the horizontal reciprocating motor 74 drives the telescopic negative pressure suction device 8 to rotate and face the capsule tea. The electric telescopic rod 81 of the telescopic negative pressure suction device 8 extends, so that its suction cup 84 sucks up the capsule tea.
