Description

Technical Field

[0001] This utility model relates to the field of tea packaging machine technology, specifically an automatic tea packaging machine. Background Technology

[0002] Currently, in the process of mass tea production, the dried tea needs to be packaged. Existing tea packaging machinery generally includes equipment for conveying, weighing, packing, and sealing tea. Since mass tea production is an assembly line operation, the weighing, packing, and sealing processes are performed by multiple packaging workers on multiple different machines. Although this method is efficient, it requires a large number of personnel, and if any link is interrupted, it will affect subsequent packaging processes. In addition, the equipment used in assembly line operations is bulky, which not only increases energy consumption and makes it difficult to control the cost of tea packaging, but also requires a large amount of production space, further increasing the input of tea production costs. Utility Model Content

[0003] This utility model provides an automatic tea packaging machine that overcomes the shortcomings described in the background art.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] An automatic tea packaging machine includes a tea sorting device for outputting tea 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. The tea sorting device has several weighing hoppers at its bottom, which output a preset weight of tea, which is then fed into the tea transfer device via the feeding plate. The packaging bag storage mechanism has several outer packaging bags stacked horizontally. The transfer mechanism uses gripping suction cups to transfer the outer packaging bags to a predetermined position at the bottom of the bag-supporting mechanism. An auxiliary suction cup is located on one side of this predetermined position, and the auxiliary suction cup, along with the gripping suction cup, opens the top opening of the outer packaging bag, allowing the tea material to escape. The rotating device feeds the tea into the bag-supporting mechanism. The bag-supporting mechanism first opens the outer packaging bag with the support claws. Then, the support claws move the outer packaging bag down to the packaging shaping mechanism. The packaging shaping mechanism clamps the bottom of the outer packaging bag with shaping clamps and moves upward to shape the three-dimensional bottom corner structure of the outer packaging bag. The bag-supporting mechanism is equipped with an inner pressure rod that moves vertically. The inner pressure rod moves down to push the tea to the bottom of the outer packaging bag and sends the outer packaging bag containing the tea into the open vacuum packaging chamber. The vacuum packaging chamber is equipped with an ejection component on the back side. After the vacuum packaging chamber vacuum seals the outer packaging bag, it is opened again and the vacuum-sealed outer packaging bag is sent out through the ejection component.

[0006] The packaging bag storage mechanism of this utility model can be adjusted to fit tea outer packaging bags of different lengths. The transfer mechanism uses a gripping suction cup to switch the outer packaging bag from a horizontal position to a vertical position, making it easier for the bag-supporting mechanism to open it later. The packaging shaping mechanism shapes the bottom of the originally flat outer packaging bag into a three-dimensional bottom corner structure.

[0007] A preferred technical solution includes an inner film winding mechanism. An inner film is selectively placed inside the outer packaging bag. At this time, the tea transfer device is a transfer chamber mechanism. The transfer chamber mechanism includes a funnel, a gripper, a first heat sealing component, and a cutting component. The inner film is wound on the inner film winding mechanism and pulled to the bottom of the transfer chamber mechanism. A gripper is installed at the bottom side of the funnel. The gripper clamps and limits the inner film and extends to the bottom of the funnel. First, the funnel and the inner film are pulled vertically a predetermined distance by the drive component. Then, the inner film is heat-sealed 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 of this utility model can optionally include an inner film inside the outer packaging bag. That is, the tea is first packaged with the inner film, and then the inner film containing the tea is vacuum-sealed inside the outer packaging bag. The inner film winding mechanism stores the inner film. It grips the inner film using a gripper at the bottom of the funnel, and the vertical movement component controls the displacement of the funnel and gripper. The inner film is then processed by a first heat-sealing component and a cutting component to form an independent film bag with an open top and closed bottom.

[0009] A preferred technical solution: The bottom of the transit warehouse mechanism is equipped with an inner film bag assembly, which includes a bag frame. Space gaps are created on both sides of the inner film along the outer edges of the spaced-apart bag frame. The inner film bag assembly helps to form a certain three-dimensional space on both sides of the inner film, facilitating the subsequent packing of tea leaves into individual film bags.

[0010] A preferred technical solution: The tea sorting device delivers a preset weight of tea through a feeding plate into a membrane bag at the bottom of the funnel. After the membrane bag is filled with tea, the top of the bag is clamped and closed by a clamping hand and transferred to the bag supporting mechanism.

[0011] If there is a discrepancy between the initial position of the clamping hand and the height at which the clamping hand feeds the tea-containing film bag into the bag-supporting mechanism, the clamping hand can be moved by using an inclined ramp.

[0012] A preferred technical solution: The tea is directly packaged 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 of the feeding plate. The bag supporting mechanism opens the outer packaging bag through the supporting claw and moves to the position that is connected with the kicking bin mechanism.

[0013] A preferred 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 it before the transfer bin mechanism. The weighing hopper sends the tea with a weight different from the preset weight into the kicking bin for rejection. The kicking bin includes a main slope that slopes downward to the 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 form a complete slope. In the open state of the L-shaped opening and closing plate, the L-shaped opening and closing plate rotates around 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 preferred 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 rail. The fixed side plate and the movable side plate cooperate to store the horizontally placed outer packaging bag. A first gear is installed at the output end of the first motor. The gear meshes with the rack to move. The rack and the linear guide rail cooperate to control the movement of the movable side plate, thereby adjusting the distance between the movable side plate and the fixed side plate.

[0015] A preferred technical solution: The transfer mechanism includes a second motor, a mating gear, a right-angle frame, and a steering arc plate. A second gear is installed at the output end of the second motor. The mating gear includes an incomplete gear and a mating handle. The incomplete gear and the mating handle are assembled into a whole. A sliding groove is provided on the mating handle. The back side of the right-angle frame is driven by the sliding groove through a connecting shaft. The gripping suction cup is installed on the right-angle frame. A quarter-circumference steering arc opening is provided on the steering arc plate. The right-angle frame and the gripping suction cup are adjusted along the steering arc opening through the connecting shaft to adjust the direction of the outer packaging bag on the gripping suction cup 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 are engaged with the two racks through a third gear to achieve clamping or separation action. 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. The vertical displacement of the frame is controlled by another motor and corresponding gears and racks.

[0017] A preferred technical solution: The vacuum packaging chamber includes a solenoid valve, a suction pipe, a suction pump, a fixed chamber cover, a movable chamber cover, a support frame, a second heat-sealing assembly, and a vacuum clamp. The movable chamber cover moves along the guide rod to fit against the side of the fixed chamber cover. The suction pump, suction pipe, and solenoid valve work together to evacuate the outer packaging bag inside the vacuum packaging chamber. The support frame moves vertically with the help of a first drive assembly. The second heat-sealing assembly heat-seals the vacuum-sealed outer packaging bag. The vacuum clamp holds the outer packaging bag after heat sealing and controls the vacuum clamp to shape the outer packaging bag vertically with the second drive assembly.

[0018] By adopting the above technical solution, the beneficial effects of this utility model are:

[0019] This utility model of an automatic tea packaging machine has a simplified overall structure and features two packaging modes: Mode 1, directly packaging tea into an outer packaging bag; and Mode 2, first packaging the tea into an inner film, and then packaging the inner film containing the tea into an outer packaging bag. The machine primarily uses common components such as motors, gears, racks, and guide rails, resulting in a simplified structure, low maintenance costs, simple operation, and high efficiency.

[0051] Example 1

[0052] like Figures 1-28As shown, this embodiment provides an automatic tea packaging machine, including 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 supporting mechanism 6, a packaging shaping mechanism 7, and a vacuum packaging chamber 8. The tea sorting device 1 has several weighing hoppers 101 at its bottom, which output tea of ​​a preset weight. The tea is fed into the tea transfer device 3 via the feeding plate 2. The packaging bag storage mechanism 4 has several outer packaging bags 41 stacked horizontally. The transfer mechanism 5 uses a gripping suction cup 51 to transfer the outer packaging bags 41 to a predetermined position at the bottom of the bag supporting mechanism 6. An auxiliary suction cup 52 is provided on one side of this predetermined position. The auxiliary suction cup 52 and the gripping suction cup 51 open the top opening of the outer packaging bag 41, allowing the tea to be released. The transfer device 3 feeds the tea into the bag-supporting mechanism 6. The bag-supporting mechanism 6 first opens the outer packaging bag 41 with the support claw 61. Then, the support claw 61 moves the outer packaging bag 41 down to the packaging shaping mechanism 7. The packaging shaping mechanism 7 clamps the bottom of the outer packaging bag 41 with the shaping clamp 71 and moves upward to shape the three-dimensional bottom corner structure 411 of the outer packaging bag 41. The bag-supporting mechanism 6 is provided with an inner pressure rod 62 that moves vertically. The inner pressure rod 62 moves down to push the tea to the bottom of the outer packaging bag 41 and sends the outer packaging bag 41 containing the tea into the vacuum packaging chamber 8, which is in an open state. The vacuum packaging chamber 8 is provided with an ejection component 81 on the back side. After the vacuum packaging chamber 8 vacuum seals the outer packaging bag 41, it is opened again and the vacuum-sealed outer packaging bag 41 is sent out through the ejection component 81.

[0053] Furthermore, it also includes an inner film winding mechanism 9, and an inner film 91 is selectively set inside the outer packaging bag 41. At this time, the tea transfer device 3 is a transfer chamber mechanism 31. The transfer chamber mechanism 31 includes a funnel 311, a gripper 312, a first heat sealing component 313, and a cutting component 314. The inner film 91 is wound on the inner film winding mechanism 9, and the inner film 91 is pulled to the bottom of the transfer chamber mechanism 31. The gripper 312 is installed on the bottom side of the funnel 311. The gripper 312 clamps the inner film 91, limits its position, and extends to the bottom of the funnel 311. First, the funnel 311 and the inner film 91 are pulled vertically a predetermined distance by the drive component 315. 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, the bottom of the transit warehouse mechanism 31 is equipped with an inner film bag assembly 32, which includes a bag frame 321. The two sides of the inner film 91 are separated by a spatial gap along the outer side of the bag frame 321. The inner film bag assembly 32 helps to form a certain three-dimensional space on both sides of the inner film 91, making it easier to pack the tea leaves into individual film bags later.

[0055] Furthermore, the tea sorting device 1 delivers a preset weight of tea through the feeding plate 2 into the film bag at the bottom of the funnel 311. After the film bag is filled with tea, the top of the film bag is clamped and closed by the clamping hand 10 and transferred into the bag supporting mechanism 6.

[0056] If there is a discrepancy between the initial position of the clamping hand 10 and the height at which the clamping hand 10 sends the film bag containing tea into the bag-supporting mechanism 6, the clamping hand 10 can be moved by adjusting the inclined slope.

[0057] Furthermore, 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 rail 46. The fixed side plate 42 and the movable side plate 43 cooperate to store the horizontally placed outer packaging bag 41. The output end of the first motor 44 is equipped with a first gear 441. The gear meshes with the rack 45 to move. The rack 45 and the linear guide rail 46 cooperate to control the movement of the movable side plate 43, thereby adjusting the distance between the movable side plate 43 and the fixed side plate.

[0058] Furthermore, the transfer mechanism 5 includes a second motor 53, a mating gear 54, a right-angle frame 55, and a steering arc plate 56. A second gear 531 is mounted on the output end of the second motor 53. The mating gear 54 includes an incomplete gear 541 and a mating handle 542. The incomplete gear 541 and the mating handle 542 are assembled as a whole. A sliding groove 5421 is provided on the mating handle 542. The back side of the right-angle frame 55 is driven by the sliding groove 5421 via a connecting shaft 551. The gripping suction cup 51 is mounted on the right-angle frame 55. The steering arc plate 56 has a quarter-circumference steering arc opening 561. The right-angle frame 55 and the gripping suction cup 51 are displaced along the steering arc opening 561 via the connecting shaft 551, adjusting the direction of the outer packaging bag 41 on the gripping suction cup 51 from a horizontal to a vertical direction. A bearing is mounted on the connecting shaft 551, allowing the direction of the outer packaging bag 41 to be adjusted under the above structural cooperation.

[0059] Furthermore, the shaping clamp 71 is divided into a first shaping clamp 711 and a second shaping clamp 712. The packaging shaping mechanism 7 uses a third motor 72 as a power source. The first shaping clamp 711 and the second shaping clamp 712 achieve clamping or separation actions by meshing with two racks through a third gear 713. 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 in the same frame. The frame controls vertical displacement through another motor and corresponding gears and racks.

[0060] Furthermore, the vacuum packaging chamber 8 includes a solenoid valve, a vacuum pipe, a vacuum pump, a fixed chamber cover 82, a movable chamber cover 83, a support frame 84, a second heat-sealing assembly 85, and a vacuum clamp 86. The movable chamber cover 83 moves along the guide rod 87 to fit against the side of the fixed chamber cover 82. The vacuum pump, vacuum pipe, and solenoid valve work together to evacuate the outer packaging bag 41 inside the vacuum packaging chamber 8. The support frame 84 moves vertically with the help of the first drive assembly 88. The second heat-sealing assembly 85 heat-seals the vacuumed outer packaging bag 41. The vacuum clamp 86 holds the outer packaging bag 41 after heat sealing and is controlled by the second drive assembly 89 to shape the outer packaging bag 41 vertically. A guide rail is installed vertically inside the vacuum packaging chamber 8. The back side of the vacuum clamp 86 slides along the guide rail. There are two vacuum clamps 86, 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 one side of the fixed chamber cover 82 is connected to the second drive assembly 89. The second drive assembly 89 uses gears to mesh with racks. A rod is installed on the rack, and the top of the rod is connected to the vacuum clamp.

[0061] To avoid the need for an auxiliary pressure rod 30 to be mounted on the funnel 311, the auxiliary pressure rod 30 is implemented using common structures such as motors, gears, racks, and guide rails.

[0062] The clamping hand 10 may include a fixed clamp, a displacement clamp, and a gripper base. The displacement clamp is driven to contact the fixed clamp by a rack and pinion mechanism. The fixed clamp and the displacement clamp are mounted on the gripper base. The clamping hand can be moved by a front-back control component and a left-right control component. The front-back control component moves laterally through the left-right control component, and the gripper base moves back and forth through the front-back control component.

[0063] Example 2

[0064] like Figures 1-28 As shown, this embodiment provides an automatic tea packaging machine. The difference between this embodiment and embodiment 1 is that this embodiment further sets up a kicking bin mechanism 11 on the basis of 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 it 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 that slopes downward to the right and an L-shaped opening and closing plate 113. In the initial state, the main slope 112 and the L-shaped opening and closing plate 113 cooperate to form a complete slope. In the open state, 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 sets an inner film 91 inside the outer packaging bag 41 to package tea. In order to further improve the function of the automatic tea packaging machine, this example 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; or it can first package tea through the inner film 91, and then place the film bag containing the tea inside the outer packaging bag 41 to complete the vacuum packaging. The kicking mechanism 11 has two functions. Function 1: When the weight of the tea weighed by the weighing hopper 101 is not up to standard (both insufficient and excessive weight are considered non-compliant), the kicking mechanism 11 will intercept the tea before the transfer mechanism 31. If the weight of the tea is up to standard, the kicking mechanism 11 will remain in its initial, side-by-side position and will not be activated. Instead, the transfer mechanism 31 will activate, grabbing the inner film 91 through the gripper 312 at the bottom of the funnel 311. The bottom of the inner film 91 will be heat-sealed by the first heat-sealing component 313, and the inner film 91 will be cut by the cutting component 314, forming an independent film bag. The film bag containing the tea will then be sent into 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 can be directly transferred to the bag-supporting mechanism 6 via the kicking mechanism. The bottom of the bag-supporting mechanism 6 will be opened by the support claw 61 to set up the outer packaging bag 41, allowing the tea to 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] In this embodiment, the automatic packaging machine directly packages the tea into the outer packaging bag 41. At this time, the tea transfer device 3 is a kicking bin mechanism. The kicking bin mechanism is controlled to move to the bottom of the feeding plate 2. The bag supporting mechanism 6 opens the outer packaging bag 41 through the supporting claw 61 and moves to a position that communicates with the kicking bin mechanism.

[0069] The automatic tea packaging machine described in Examples 1-3 achieves both packaging with and without an inner film 91 by selecting the specific structure of the tea transfer device 3. The automatic packaging machine in Example 1 can achieve tea packaging with an inner film 91 through the corresponding structure. The automatic packaging machine in Example 2, based on Example 1, can achieve both tea packaging with and without an inner film 91 through the corresponding structure. Therefore, the automatic packaging machine with the best effect among Examples 1-3 is the automatic packaging machine in Example 2, while the automatic packaging machine in Example 3 achieves tea packaging without an inner film 91 through the corresponding structure.

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

[0071] The automatic tea packaging machine has a housing 100, within which all components are installed. A tea sorting device 1 is located at the top of the housing 100. This device typically includes a tea storage bin for storing tea leaves. To prevent excessive concentration of tea leaves, a dispersing rod 20 is also included to break up the tea. A vibrating disc 21 is located at the bottom of the tea storage bin. Sensors can be installed at corresponding positions on the housing 100 to detect the presence of tea leaves. The vibrating disc 21 feeds the tea leaves into a weighing hopper 101, which primarily weighs the tea leaves and includes an openable cover 22. All components of the tea sorting device 1 can utilize existing or similar technologies. The automatic tea packaging machine is equipped with a touchscreen display and corresponding physical buttons. The touchscreen display also stores the corresponding control system, allowing for the selection of tea packaging with or without an inner film 91.

[0072] The packaging bag storage mechanism 4 is used to store the outer packaging bag 41 of tea. It can be adjusted to accommodate tea outer packaging bags 41 of different lengths. The transfer mechanism 5 uses the gripping suction cup 51 to switch the outer packaging bag 41 from a horizontal position to a vertical position, so that the bag opening mechanism 6 can open it later. The packaging shaping mechanism 7 shapes the bottom of the originally flat outer packaging bag 41 into a three-dimensional bottom corner structure 411. When packaging with inner film 91 is selected, the inner film winding mechanism 9 rotates to output the inner film 91. The inner film winding mechanism 9 holds the inner film 91 and uses the gripper 312 at the bottom end of the funnel 311 to grip the inner film 91. The funnel 311 and gripper 312 are controlled by the corresponding vertical moving components. The inner film 91 is displaced and processed by the first heat-sealing assembly 313 and the cutting assembly 314 to form an independent film bag with an open top and a closed bottom. Then, the funnel 311 continues to move downward, displaces to the bottom of the feeding plate 2, and matches the feeding plate 2. The cover plate 22 on the weighing hopper 101 is opened, and the tea leaves are fed into the film bag. The funnel 311 moves downward to the position of the clamping hand 10, the gripper 312 on the funnel 311 is released from the gripping state, the clamping hand 10 clamps the top of the closed film bag, and transfers it to the bag-supporting mechanism 6 along a predetermined displacement path. The bag-supporting mechanism 6 is controlled to move upward, so that the transfer mechanism 5 can transfer the outer packaging bag 41 from the bottom of the packaging bag storage mechanism 4 to the bag-supporting mechanism through the gripping suction cup 51.
