Description

Technical Field

[0001] The present invention relates to the technical field of tea packaging machines, and specifically to an automatic tea packaging machine. Background Art

[0002] At present, during the mass production of tea, it is necessary to perform packaging operations on the dried tea. Existing tea packaging machines generally include equipment for tea transportation, weighing, packing, and sealing. Since the mass production of tea is a streamlined operation, the weighing, packing, and sealing processes during tea packaging are carried out by multiple packaging workers on multiple different devices. Although this has a high packaging efficiency, it requires a large number of personnel. Moreover, once an interruption occurs in one of these links, it will affect the subsequent packaging process. In addition, the equipment for streamlined operation is bulky, which not only increases energy consumption, is not conducive to controlling the cost of tea packaging, but also requires a large amount of workshop space, further increasing the investment in tea production costs. Summary of the Invention

[0003] The present invention provides an automatic tea packaging machine, which overcomes the deficiencies described in the background art.

[0004] The technical solution adopted by the present invention to solve its technical problems is as follows:

[0005] An automatic tea packaging machine includes a tea sorting device for outputting the tea inner material, a feeding plate, a tea transfer device, a packaging bag storage mechanism, a transfer mechanism, a bag-supporting mechanism, a packaging shaping mechanism, and a vacuum packaging chamber. Several weighing hoppers are provided at the bottom of the tea sorting device. The weighing hoppers output tea of a preset weight, which is sent into the tea transfer device through the feeding plate. The packaging bag storage mechanism horizontally stacks several outer packaging bags. The transfer mechanism transfers the outer packaging bags to a predetermined position at the bottom of the bag-supporting mechanism through a grasping suction cup. And an auxiliary suction cup is provided on one side of this predetermined position. The top opening of the outer packaging bag is opened by the auxiliary suction cup and the grasping suction cup. The tea transfer device sends the tea into the bag-supporting mechanism. The bag-supporting mechanism first opens the outer packaging bag through a bag-supporting claw, and then the bag-supporting claw and the outer packaging bag move downward to the packaging shaping mechanism together. The packaging shaping mechanism clamps the bottom end of the outer packaging bag through a shaping clip and moves upward to shape the three-dimensional bottom corner structure of the outer packaging bag. An inner pressing rod that moves vertically is provided in the bag-supporting mechanism. The inner pressing rod moves downward to push the tea to the bottom of the outer packaging bag, and the outer packaging bag containing the tea is sent into the open vacuum packaging chamber. A pushing component is provided on the back side of the vacuum packaging chamber. After the vacuum packaging chamber vacuum-seals the outer packaging bag and opens it again, the vacuum-sealed outer packaging bag is sent out through the pushing component.

[0006] The packaging bag storage mechanism in the present invention can be adjusted to adapt to tea outer packaging bags of different lengths. The transfer mechanism switches the outer packaging bag from a horizontally placed state to a vertical state through a grasping suction cup, facilitating the subsequent opening of the bag by the bag-opening mechanism. The packaging shaping mechanism shapes the bottom of the outer packaging bag, which was originally in a planar state, into a three-dimensional bottom corner structure.

[0007] A preferred technical solution: It further includes an inner film winding and unwinding mechanism. An inner film is selectively arranged inside the outer packaging bag. At this time, the tea transfer device is a transfer bin mechanism. The transfer bin mechanism includes a funnel, a grasping clamp, a first heat-sealing component, and a cutting component. The inner film is wound on the inner film winding and unwinding mechanism, and the inner film is drawn to the bottom end of the transfer bin mechanism. A grasping clamp is installed at the bottom side of the funnel. The grasping clamp clamps and positions the inner film and penetrates through to the bottom end of the funnel. First, the driving component is used to control the funnel and the inner film to be drawn vertically by a predetermined distance. Subsequently, the inner film is heat-sealed and closed by the first heat-sealing component. Finally, the inner film is cut by the cutting component to form a film bag with an open top and a closed bottom.

[0008] The automatic tea packaging machine in the present invention can selectively arrange an inner film inside the outer packaging bag, that is, first pack the tea with the inner film, and then pack the inner film containing the tea into the outer packaging bag for vacuum packaging. The inner film winding and unwinding mechanism is used to store the inner film. It grabs the inner film through the grasping clamp at the bottom side of the funnel, and controls the displacement of the funnel and the grasping clamp to grab the inner film through the corresponding vertical movement component. The inner film is processed by the first heat-sealing component and the cutting component to form an independent film bag with an open top and a closed bottom.

[0009] A preferred technical solution: An inner film bag-opening component is installed at the bottom end of the transfer bin mechanism. The inner film bag-opening component includes a bag-opening frame. Space gaps are separated on the outer sides of the bag-opening frame where the two sides of the inner film are arranged at intervals. By means of the inner film bag-opening component, a certain three-dimensional space is formed on both sides of the inner film, facilitating the subsequent loading of tea into the independent film bag.

[0010] A preferred technical solution: The tea sorting device sends out tea of a preset weight, which is sent into the film bag at the bottom end of the funnel through a feeding plate. After the film bag containing the tea is filled, the top end of the film bag is clamped and closed by a clamping hand and transferred into the bag-opening mechanism.

[0011] When there is a deviation between the clamping hand at the initial position and the height position where the clamping hand sends the film bag containing the tea into the bag-opening mechanism, the inclined slope can be used to cooperate with the movement of the clamping hand.

[0012] A preferred technical solution: The tea is directly packed into the outer packaging bag. At this time, the tea transfer device is a kicking bin mechanism. The kicking bin mechanism is controlled to move to the bottom end of the feeding plate. The bag-opening mechanism opens the outer packaging bag through a bag-opening claw and moves to a position communicating with the kicking bin mechanism.

[0013] A better technical solution: The tea transfer device also includes a kicking bin mechanism. When the weight of the tea weighed by the weighing hopper does not meet the requirements, the kicking bin mechanism starts to intercept before the transfer bin mechanism. The weighing hopper sends the tea with a weight different from the preset weight into the kicking bin for removal. The kicking bin includes a main slope inclined to the lower right and an L-shaped opening and closing plate. In the initial state of the L-shaped opening and closing plate, the main slope and the L-shaped opening and closing plate cooperate to construct a complete slope; in the open state of the L-shaped opening and closing plate, the L-shaped opening and closing plate rotates with the connecting rod as the rotation base point. The L-shaped opening and closing plate intercepts and changes the tea conveying path, and conveys the tea to the collection container for storage.

[0014] A better technical solution: The packaging bag storage mechanism includes a fixed side plate, a movable side plate, a first motor, a rack, and a linear guide. The fixed side plate and the movable side plate cooperate to store horizontally placed outer packaging bags. The first gear is installed at the output end of the first motor. The gear engages with the rack for displacement. The rack and the linear guide cooperate to control the displacement of the movable side plate, thereby adjusting the distance between the movable side plate and the fixed side.

[0015] A better technical solution: the transfer mechanism includes a second motor, a matching tooth part, a right-angle frame, and a steering arc plate. The second gear is installed at the output end of the second motor. The matching tooth part includes an incomplete gear and a matching handle. The incomplete gear and the matching handle are assembled into a whole. A sliding groove is arranged on the matching handle. The back side of the right-angle frame is matched with the sliding groove through a connecting shaft. The grabbing suction cup is installed on the right-angle frame. A steering arc opening with a quarter of the circumference is arranged on the steering arc plate. The right-angle frame and the grabbing suction cup are displaced along the steering arc opening through the connecting shaft to adjust the direction of the outer packaging bag on the grabbing suction cup. The direction of the outer packaging bag is adjusted from the horizontal direction to the vertical direction.

[0016] A preferred technical solution: the shaping clamp is divided into a first shaping clamp and a second shaping clamp. The first shaping clamp and the second shaping clamp achieve clamping or separation action through the meshing cooperation of the third gear and the two racks. The first shaping clamp and the second shaping clamp are respectively connected to one of the two racks, and the third gear is installed at the output end of the third motor. The first shaping clamp, the second shaping clamp, the third motor, the third gear and the two racks are located in the same frame, and the frame controls the vertical displacement through another motor and the corresponding gears and racks.

[0017] A better technical solution: The vacuum packaging chamber includes a solenoid valve, an exhaust pipe, an exhaust pump, a fixed chamber cover, a movable chamber cover, a supporting frame, a second heat sealing component, and a vacuum clamp. The movable chamber cover is displaced along the guide rod to fit onto the side end of the fixed chamber cover. The outer packaging bag in the vacuum packaging chamber is evacuated through the cooperation of the exhaust pump, the exhaust pipe, and the solenoid valve. The supporting frame is vertically displaced through the cooperation of the first driving component. The second heat sealing component heat-seals the vacuumized outer packaging bag. The vacuum clamp clamps the outer packaging bag after heat sealing, and controls the vacuum clamp to shape the outer packaging bag in the vertical direction through the second driving component.

[0018] By adopting the above technical solutions, the beneficial effects of the present invention are as follows:

[0019] The overall structure of the automatic tea packaging machine of the present invention is streamlined, and one device has two packaging modes. Mode 1: directly package the tea into the outer packaging bag; Mode 2: first package the tea into the inner film, and then package the inner film with the tea into the outer packaging bag. The whole machine mostly adopts common structures such as motors, gears, racks, and guide rails, with a streamlined structure, low maintenance costs, simple and efficient operations.

[0051] Embodiment 1

[0052] As Figures 1 - 28As shown, the present embodiment provides an automatic tea packaging machine, comprising a tea sorting device 1 for outputting tea material, a feeding plate 2, a tea transfer device 3, a packaging bag storage mechanism 4, a transfer mechanism 5, a bag support mechanism 6, a packaging shaping mechanism 7, and a vacuum packaging chamber 8. A plurality of weighing hoppers 101 are arranged at the bottom of the tea sorting device 1. The weighing hoppers 101 output tea of ​​preset weight and feed it into the tea transfer device 3 through the feeding plate 2. A plurality of outer packaging bags 41 are stacked horizontally in the packaging bag storage mechanism 4. The transfer mechanism 5 transfers the outer packaging bag 41 to a predetermined position at the bottom of the bag support mechanism 6 through a grabbing suction cup 51, and an auxiliary suction cup 52 is arranged on one side of the predetermined position. The top opening of the outer packaging bag 41 is opened by the auxiliary suction cup 52 and the grabbing suction cup 51, and the tea is The transfer device 3 sends the tea leaves into the bag-holding mechanism 6, which first opens the outer packaging bag 41 through the supporting claws 61, and then the supporting claws 61 cooperate with the outer packaging bag 41 to move downward to the packaging shaping mechanism 7. The packaging shaping mechanism 7 clamps the bottom end of the outer packaging bag 41 through the shaping clamp 71, and moves upward to shape the three-dimensional bottom corner structure 411 of the outer packaging bag 41. The bag-holding mechanism 6 is provided with an internal pressure rod 62 that moves along the vertical direction. The internal pressure rod 62 moves downward to push the tea leaves to the bottom of the outer packaging bag 41, and the outer packaging bag 41 containing the tea leaves is sent into the vacuum packaging chamber 8 in an open state. The back side of the vacuum packaging chamber 8 is provided with a push-out component 81. The vacuum packaging chamber 8 vacuum-seales the outer packaging bag 41 and then opens again, and the vacuum-sealed outer packaging bag 41 is sent out through the push-out component 81.

[0053] Furthermore, it also includes an inner film winding and unwinding mechanism 9, and an inner film 91 is optionally set in the outer packaging bag 41. At this time, the tea transfer device 3 is a transfer warehouse mechanism 31, and the transfer warehouse mechanism 31 includes a funnel 311, a gripping hand 312, a first heat sealing component 313, and a cutting component 314. The inner film 91 is wound on the inner film winding and unwinding mechanism 9, and the inner film 91 is pulled to the bottom end of the transfer warehouse mechanism 31, and a gripping hand 312 is installed at the bottom side end of the funnel 311. The gripping hand 312 clamps the inner film 91 to limit the position and passes through the bottom end of the funnel 311. The funnel 311 and the inner film 91 are first controlled by the driving component 315 to be pulled a predetermined distance in the vertical direction, and then the inner film 91 is heat-sealed by the first heat sealing component 313. Finally, the inner film 91 is cut by the cutting component 314 to form a film bag with an open top and a closed bottom.

[0054] Furthermore, an inner film bagging assembly 32 is installed at the bottom of the transfer bin mechanism 31, and the inner film bagging assembly 32 includes a bagging frame 321. The two sides of the inner film 91 are separated by a space gap along the outer side of the bagging frame 321 arranged at intervals. The inner film bagging assembly 32 assists the two sides of the inner film 91 to form a certain three-dimensional space, which is convenient for the tea leaves to be subsequently loaded into independent film bags.

[0055] Further, the tea sorting device 1 sends out a preset weight of tea, which is sent into the membrane bag at the bottom of the funnel 311 through the feeding plate 2. The top of the membrane bag filled with tea is clamped and closed by the clamping hand 10 and transferred into the bag supporting mechanism 6.

[0056] When there is a deviation between the clamping hand 10 at the initial position and the height position where the clamping hand 10 sends the membrane bag packed with tea into the bag supporting mechanism 6, the clamping hand 10 can be moved by cooperating with the inclined slope.

[0057] Further, the packaging bag storage mechanism 4 includes a fixed side plate 42, a movable side plate 43, a first motor 44, a rack 45, and a linear guide 46. The fixed side plate 42 and the movable side plate 43 cooperate to store the outer packaging bags 41 placed horizontally. The output end of the first motor 44 is installed with a first gear 441. The gear meshes with the rack 45 for displacement. The rack 45 and the linear guide 46 cooperate to control the displacement of the movable side plate 43, thereby adjusting the distance between the movable side plate 43 and the fixed side.

[0058] Further, the transfer mechanism 5 includes a second motor 53, a mating tooth member 54, a right-angle frame 55, and a steering arc plate 56. The output end of the second motor 53 is installed with a second gear 531. The mating tooth member 54 includes an incomplete gear 541 and a mating handle 542. The incomplete gear 541 and the mating handle 542 are assembled into an integral body. A sliding slot 5421 is provided on the mating handle 542. The back side of the right-angle frame 55 is in transmission cooperation with the sliding slot 5421 through a connecting shaft 551. The grasping suction cup 51 is installed on the right-angle frame 55. A quarter-circular steering arc opening 561 is provided on the steering arc plate 56. The right-angle frame 55 and the grasping suction cup 51 are displaced along the steering arc opening 561 through the connecting shaft 551 to adjust the direction of the outer packaging bag 41 on the grasping suction cup 51. The direction of the outer packaging bag 41 is adjusted from the horizontal direction to the vertical direction. A bearing is installed on the connecting shaft 551, so that the direction of the outer packaging bag 41 is adjusted under the cooperation of the above structures.

[0059] Further, the shaping clamp 71 is divided into a first shaping clamp 711 and a second shaping clamp 712. The packaging shaping mechanism 7 uses the third motor 72 as the power source. The first shaping clamp 711 and the second shaping clamp 712 realize the clamping or separating action through the meshing cooperation of the third gear 713 with two racks. The first shaping clamp 711 and the second shaping clamp 712 are respectively connected to one of the two racks, and the third gear 713 is installed at the output end of the third motor 72. The first shaping clamp 711, the second shaping clamp 712, the third motor 72, the third gear 713, and the two racks are located within the same frame. The frame controls the vertical displacement through another motor and the corresponding gears and racks.

[0060] Furthermore, the vacuum packaging chamber 8 includes a solenoid valve, an exhaust pipe, an exhaust pump, a fixed chamber cover 82, a movable chamber cover 83, a supporting frame 84, a second heat sealing component 85, and a vacuum clamp 86. The movable chamber cover 83 is displaced along the guide rod 87 to fit the side end of the fixed chamber cover 82. The outer packaging bag 41 in the vacuum packaging chamber 8 is evacuated by the cooperation of the exhaust pump, the exhaust pipe, and the solenoid valve. The supporting frame 84 is vertically displaced by the first driving component 88. The second heat sealing component 85 heat-seals the vacuumized outer packaging bag 41. The vacuum clamp 86 clamps the outer packaging bag 41 after heat sealing, and controls the vacuum clamp 86 to shape the outer packaging bag 41 in the vertical direction through the second driving component 89. A guide rail is installed in the vacuum packaging chamber 8 along the vertical direction, and the back side of the vacuum clamp 86 slides along the guide rail. The vacuum clamp 86 has two parts, which are in contact with each other and attached to the surface of the outer packaging bag. The bottom end of the vacuum clamp structure located on the side of the fixed chamber cover 82 is connected to the second driving component 89. The second driving component 89 uses a gear meshing rack, and a rod body is installed on the rack, and the top end of the rod body is connected to this vacuum clamp.

[0061] In order to avoid installing the auxiliary pressure rod 30 on the funnel 311, the auxiliary pressure rod 30 is realized by cooperating with common structures such as a motor, a gear, a rack, and a guide rail.

[0062] The clamping hand 10 may include a fixed clamping hand, a displacement clamping hand, and a gripping seat. The displacement clamping hand is driven to contact the fixed clamping hand through the displacement of the rack. The fixed clamping hand and the displacement clamping hand are installed on the gripping seat. The clamping hand can be controlled to move by the front and rear control components and the left and right control components. The front and rear control components are laterally displaced by the left and right control components, and the gripping seat is displaced forward and backward by the front and rear control components.

[0063] Example 2

[0064] like Figures 1 - 28 As shown, the present embodiment provides an automatic tea packaging machine, and the difference between the present embodiment and the embodiment 1 is that the present embodiment further arranges a kicking bin mechanism 11 on the basis of the embodiment 1, that is, the tea transfer device 3 not only includes the transfer bin mechanism 31, but also includes the kicking bin mechanism 11. When the weight of the tea weighed by the weighing hopper 101 does not meet the requirements, the kicking bin mechanism 11 starts to intercept before the transfer bin mechanism 31. The weighing hopper 101 sends the tea with a weight different from the preset weight into the kicking bin for rejection. The kicking bin 111 includes a main slope 112 inclined to the lower right and an L-shaped opening and closing plate 113. In the initial state of the L-shaped opening and closing plate 113, the main slope 112 cooperates with the L-shaped opening and closing plate 113 to construct a complete slope; in the open state of the L-shaped opening and closing plate 113, the L-shaped opening and closing plate 113 rotates with the connecting rod as the rotation base point. The L-shaped opening and closing plate intercepts and changes the tea conveying path, and conveys the tea to the collection container for storage.

[0065] The automatic tea packaging machine in Example 1 can be understood as a packaging machine that packages tea with an inner film 91 inside an outer packaging bag 41. In order to further improve the function of the automatic tea packaging machine, this embodiment introduces a kicking bin mechanism 11, so that an automatic tea packaging machine can vacuum-package tea directly through the outer packaging bag 41 without the inner film 91; it can also first package the tea with the inner film 91, and then place the film bag packaged with the tea inside the outer packaging bag 41 to complete the vacuum packaging. That is, the kicking bin mechanism 11 has two functions. Function 1: when the weight of tea weighed by the weighing hopper 101 does not meet the requirements, the weight of tea is insufficient or excessive, and the kicking bin mechanism 11 is started before the transfer bin mechanism 31 to intercept; when the weight of tea meets the requirements, the kicking bin mechanism 11 is always located at the initial side position, the kicking bin mechanism 11 is not started, and the transfer bin mechanism 31 is started, and the inner film 91 is grabbed by the gripping hand 312 at the bottom of the funnel 311, and the bottom of the inner film 91 is heat-sealed by the first heat-sealing component 313, and the inner film 91 is cut by the cutting component 314, so that the inner film 91 forms an independent film bag, and then the film bag packed with tea is sent to the outer packaging bag 41 at the bottom of the bag-supporting mechanism 6 for packaging. Function 2: Without using the inner film 91, the tea is directly transferred to the bag-supporting mechanism 6 by the kicking bin mechanism, and the bottom of the bag-supporting mechanism 6 is opened by the supporting claw 61 to set the outer packaging bag 41, so that the tea can be directly packaged in the outer packaging bag 41.

[0066] Example 3

[0067] like Figures 1 - 28 As shown, this embodiment provides an automatic tea packaging machine.

[0068] The automatic packaging machine in this embodiment packs the tea leaves directly into the outer packaging bag 41. At this time, the tea transfer device 3 is a kicking bin mechanism, which controls the kicking bin mechanism to move to the bottom end of the feeding plate 2. The bag-supporting mechanism 6 opens the outer packaging bag 41 through the supporting claws 61 and moves to a position that is connected to the kicking bin mechanism.

[0069] The automatic packaging machine for tea described in Examples 1-3 realizes packaging methods with or without inner membrane 91 by selecting the specific structure of the tea transfer device 3. The automatic packaging machine in Example 1 can realize packaging of tea with inner membrane 91 through the corresponding structure. The automatic packaging machine in Example 2 can realize packaging of tea with or without inner membrane 91 through the corresponding structure on the basis of Example 1. Therefore, the automatic packaging machine with the best effect in Examples 1-3 is the automatic packaging machine in Example 2, and the automatic packaging machine in Example 3 realizes packaging of tea without inner membrane 91 through the corresponding structure.

[0070] Taking the automatic tea packaging machine in Example 2 as an example, its overall structure and packaging process are described in detail:

[0071] The automatic tea packaging machine has a housing 100, and each structure is commonly installed inside the housing 100. At the top of the housing 100, a tea sorting device 1 is provided. The tea sorting device 1 usually includes a tea bin for storing tea. To prevent the tea from being too concentrated, a dispersing rod 20 for dispersing the tea is also provided. A vibrating disk 21 is provided at the bottom end of the tea bin. A sensor can be provided at a corresponding position of the housing 100 to detect whether there is tea. The vibrating disk 21 feeds the tea into a weighing hopper 101. The weighing hopper 101 mainly weighs the tea and is provided with an openable and closable cover plate 22. The above tea sorting device 1 can all adopt the same or similar technologies in the prior art. The automatic tea packaging machine is provided with a touch display screen and corresponding physical buttons. At the same time, the touch display screen stores a corresponding control system, enabling the selection of tea packaging with an inner film 91 and tea packaging without an inner film 91 to be realized.

[0072] The packaging bag storage mechanism 4 is used to store the outer packaging bags 41 of tea, and it can be adjusted to adapt to different lengths of the outer packaging bags 41 of tea. The transfer mechanism 5 switches the outer packaging bag 41 from the horizontal placement state to the vertical state through the grasping suction cup 51, which facilitates the subsequent opening of the outer packaging bag 41 by the bag-opening mechanism 6. The packaging and shaping mechanism 7 shapes the bottom of the outer packaging bag 41 originally in a planar state into a three-dimensional bottom corner structure 411. When choosing to package with the inner film 91, the inner film winding mechanism 9 rotates and outputs the inner film 91 in cooperation. The inner film 91 is stored on the inner film winding mechanism 9. It grabs the inner film 91 through the clamping hand 312 at the bottom side of the funnel 311, and controls the displacement of the funnel 311 and the clamping hand 312 to grab the inner film 91 through the corresponding vertical movement component. The inner film 91 is processed by the first heat-sealing component 313 and the cutting component 314 to form an independent film bag with an open top and a closed bottom. Subsequently, the funnel 311 continues to move downward, displaces to the bottom end of the feeding plate 2, and matches with the feeding plate 2. The cover plate 22 on the weighing hopper 101 is opened, and the tea is fed into the film bag. The funnel 311 moves downward to the position of the clamping hand 10. The clamping hand 312 on the funnel 311 releases the grasping state. The clamping hand 10 clamps and closes the top of the film bag, and transfers it to the bag-opening mechanism 6 along the predetermined displacement path. Control the bag-opening mechanism 6 to move upward, which facilitates the transfer mechanism 5 to transfer the outer packaging bag 41 from the bottom end of the packaging bag storage mechanism 4 to a predetermined position at the bottom end of the bag-opening mechanism 6 through the grasping suction cup 51. The transfer mechanism 5 switches the outer packaging bag 41 from the horizontal state to the vertical state, and the grasping suction cup 51 cooperates with the auxiliary suction cup 52 to open the outer packaging bag 41. The bag-opening mechanism 6 moves downward. The bag-opening mechanism 6 first opens the outer packaging bag 41 through the bag-opening claws 61. The packaging and shaping mechanism 7 clamps the bottom end of the outer packaging bag 41 through the shaping clamp 71 and moves upward to shape the three-dimensional bottom corner structure 411 of the outer packaging bag 41. Subsequently, the inner pressure rod 62 in the bag-opening mechanism 6 moves downward to push the tea to displace to the bottom of the outer packaging bag 41, and sends the outer packaging bag 41 containing the tea into the opened vacuum packaging chamber 8. The vacuum packaging chamber 8 includes an electromagnetic valve, an air extraction pipe, an air extraction pump, a fixed chamber cover 82, a movable chamber cover 83, a supporting frame 84, a second heat-sealing component 85, and a vacuum clamp 86. The movable chamber cover 83 displaces along the guide rod and fits to the side end of the fixed chamber cover 82. At this time, the vacuum packaging chamber 8 is airtight. The outer packaging bag 41 in the vacuum packaging chamber 8 is evacuated through the cooperation of the air extraction pump, the air extraction pipe, and the electromagnetic valve. Subsequently, the second heat-sealing component 85 heat-seals the evacuated outer packaging bag 41. The supporting frame 84 moves downward vertically through the cooperation of the first driving component 88. The vacuum clamp 86 clamps the outer packaging bag 41, and controls the vacuum clamp 86 to displace in the vertical direction to shape the outer packaging bag 41. The vacuum packaging chamber 8 is opened, and the outer packaging bag 41 packaged with tea is pushed out through the pushing component 81.

[0073] When choosing not to use the inner film 91, the tea is directly transferred to the bag-opening mechanism 6 through the kicking material mechanism. At this time, the funnel 311 structure does not operate.

[0074] The above is only a preferred embodiment of the present invention, and thus the scope of implementation of the present invention cannot be limited thereby. That is, equivalent changes and modifications made according to the scope of the present invention patent and the content of the specification should still fall within the scope covered by the present invention.
