Description

Technical Field

[0001] This utility model relates to the field of tea packaging technology, and in particular to a production line for packaging irregularly shaped tea cakes. Background Technology

[0002] In the production and processing of compressed tea cakes, packaging is a crucial process for ensuring product quality and enhancing its added value. Currently, in addition to the traditional round shape, oval and other irregularly shaped tea cakes are gaining popularity among consumers due to their unique appearance and cultural connotations. Existing tea cake packaging production lines are primarily designed and developed for round tea cakes, with their core positioning components often employing centering mechanisms based on a circular outline. These centering mechanisms typically utilize the central symmetry of a round tea cake, achieving positioning through radial clamping or pushing. However, for oval tea cakes, due to the difference between their major and minor axes and the lack of central symmetry inherent in a round structure, traditional centering mechanisms cannot accurately identify their geometric center and outline boundaries, resulting in a significant decrease in positioning accuracy.

[0003] To address the aforementioned positioning issues, some manufacturers still rely on manual placement of tea cakes. However, manual operation is not only inefficient and unable to meet the demands of large-scale production, but also susceptible to subjective influences from operators, leading to positional shifts and angular deviations at the packaging station. This, in turn, affects the subsequent packaging and sealing quality, resulting in uneven packaging, incomplete sealing, and other defects, impacting the overall product quality and market competitiveness. Some companies have attempted to use mechanical pushing methods to position oval tea cakes, but existing mechanical positioning equipment often employs rigid, fixed-size clamping structures, lacking the ability to adapt to irregular contours. When clamping and positioning oval tea cakes, the rigid clamping structure cannot perfectly conform to the irregular contours, easily generating excessive compressive stress in localized areas at the edges. Especially for brittle, compressed tea cakes, this excessive localized compressive force can easily cause the edges to crack, crumble, or even deform, severely affecting the product's appearance integrity and quality stability, increasing production losses and costs. In view of this, this utility model proposes a production line for packaging irregularly shaped tea cakes. Utility Model Content

[0023] Example

[0024] like Figure 1 and Figure 4 As shown, this utility model proposes a production line for packaging irregularly shaped tea cakes, including two sets of discharge mechanisms 1. The discharge mechanism 1 is used to arrange and transport the tea cakes to the packaging position. The discharge mechanism 1 includes a vibrating plate 11. After the tea cakes are poured into the vibrating plate 11, the vibration of the vibrating plate 11 arranges the tea cakes and discharges them. The vibrating plate 11 is existing technology and will not be described in detail here. A first conveyor belt 12 is installed at the output position of the vibrating plate 11. A second conveyor belt 13 is arranged below the end of the first conveyor belt 12 away from the vibrating plate 11. The tea cakes discharged from the vibrating plate 11 are transported by the vibrating plate 11 and the first conveyor belt 12. At the same time, the length of the vibrating plate 11 and the first conveyor belt 12 is suitable for temporarily storing multiple tea cakes, and photoelectric sensors are used to sense the distribution of tea cakes. An inclined plate 14 is arranged at the end of the first conveyor belt 12 away from the vibrating plate 11, so that the tea cakes at the end of the first conveyor belt 12 can slide onto the second conveyor belt 13 through the inclined plate 14. The top of the first conveyor belt 12 and the second conveyor belt 13 are provided with two sets of baffles 15. The baffles 15 limit the movement of the tea cake and prevent the tea cake from rotating. The distance between the two sets of baffles 15 is less than the length of the tea cake.

[0025] For further details, please refer to Figures 1 to 4The aforementioned packaging production line includes a pushing assembly 2 positioned between two sets of discharge mechanisms 1. The pushing assembly 2 is used to push the tea cake into the packaging bag. The pushing assembly 2 includes two sets of first push rods 21 mounted on the frame. The output ends of the two sets of first push rods 21 are respectively fixedly connected to a movable frame 22. Push blocks 23 are respectively fixedly connected to opposite sides of the two sets of movable frames 22. The push blocks 23 have arc-shaped grooves that cooperate with the tea cake. After the first push rods 21 are started, the movable frames 22 drive the push blocks 23 to contact the tea cake, pushing the tea cake out from the end of the second conveyor belt 13. Two sets of push plates 24 are arranged between the two sets of push blocks 23. Each push plate 24 has a slot 29 near the end of the bag-opening component 4. A limiting part 210 is provided on the opposite side of each slot 29. The limiting part 210 ensures that one side of the tea cake contacts and is positioned when the push block 23 moves the tea cake. Simultaneously, the slots 29 hold the tea cake in place as the push plate 24 moves, facilitating the movement of the tea cake while preventing it from shifting position. A connecting plate 25 is fixedly connected between the two sets of push plates 24. A first slider 26 is fixedly connected to the bottom of the connecting plate 25. A first slide rail 27 is slidably connected to the first slider 26 and mounted on the frame. The limiting action of the first slider 26 and the first slide rail 27 ensures smooth movement of the push plate 24 and the connecting plate 25. The frame is also equipped with a first linear motor 28. The moving end of the first linear motor 28 is fixedly connected to the connecting plate 25. After the first linear motor 28 is started, it drives the connecting plate 25 to move, thereby driving the two sets of push plates 24 to move synchronously.

[0026] Furthermore, such as Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the packaging production line includes a mouth-supporting mechanism 3 located at the pusher assembly 2. This mechanism prevents the packaging bag opening from closing during tea feeding. The mouth-supporting mechanism 3 includes a movable plate 31 positioned between two sets of second conveyor belts 13. A second slider is fixedly connected to the bottom of the movable plate 31 and slidably connected to a first slide rail 27. The second slider ensures smooth movement of the movable plate 31. Two sets of synchronous plates 32 are positioned above the movable plate 31. Two sets of pushers 23 move to the bottom of the synchronous plates 32 and push the tea cake between the movable plate 31 and the synchronous plates 32. Multiple sets of connecting columns 33 are fixedly connected between the synchronous plates 32 and the movable plate 31, allowing the synchronous plates 32 and the movable plate 31 to move synchronously. Two sets of limiting plates 34 are respectively provided between the two sets of synchronization plates 32 and the moving plate 31. The limiting plates 34 are fixedly connected to the moving plate 31. Two sets of push plates 24 are slidably connected between the two sets of limiting plates 34. The setting of the limiting plates 34 limits the tea cake when the push plate 24 pushes it. Two sets of support plates 35 are provided between the two sets of limiting plates 34. The two sets of support plates 35 are fixedly connected to the moving plate 31 and the synchronization plate 32 respectively. The setting of the limiting plates 34 and support plates 35 facilitates insertion into the packaging bag opening and prevents the packaging bag opening from closing when pushing the tea cake. A second push rod 36 is provided below the moving plate 31 and installed on the frame. A push plate 37 is fixedly connected between the output end of the second push rod 36 and the moving plate 31. After the second push rod 36 is started, it drives the moving plate 31 to move through the push plate 37, which facilitates the movement of one end of the limiting plate 34 and the support plate 35 into the bag opening. A fixed frame 38 is fixedly connected above the synchronization plate 32. The fixed frame 38 is located at the slot 29. A third push rod 39 is installed on the top of the fixed frame 38. The output end of the third push rod 39 passes through the synchronization plate 32. After activation, the third push rod 39 extends to press down on the tea cake, ensuring that the position of the tea cake is fixed after the push block 23 pushes the tea cake to one end of the push plate 24. This prevents the tea cake from shifting position when the moving plate 31 moves, thus preventing the slot 29 at one end of the push plate 24 from failing to hold the tea cake. During operation, the push block 23 pushes the tea cake under the third push rod 39, and the third push rod 39 extends to fix the tea cake. Then, the moving plate 31 moves, causing the limiting plate 34 and the support plate 35 to enter the bag opening. Finally, the push plate 24 moves to push the tea cake into the packaging bag.

[0027] For details, please refer to Figure 4 and Figure 5The aforementioned packaging production line includes a bag-opening assembly 4, which is used to open the packaging bag opening. The bag-opening assembly 4 includes a fixed plate 41, with positioning plates 42 fixedly connected to both ends of the fixed plate 41, and the positions of the fixed plate 41 and the positioning plates 42 are fixed. Multiple sets of top rods 43 are installed on the top of the upper set of positioning plates 42, and a top plate 44 is fixedly connected to the top of the multiple sets of top rods 43, with the position of the top plate 44 fixed. A servo motor 45 is installed on the top of the top plate 44, and the output end of the servo motor 45 passes through the top plate 44 and is fixedly connected to a bidirectional threaded rod 46 via a coupling. After the servo motor 45 starts, it drives the bidirectional threaded rod 46 to rotate. The bidirectional threaded rod 46 is rotatably connected to the two sets of positioning plates 42, and the bidirectional threaded rod 46 rotates while remaining in its original position. The two ends of the bidirectional threaded rod 46 have opposite thread directions and are respectively threadedly connected to moving blocks 47. When the bidirectional threaded rod 46 rotates, it drives the two sets of moving blocks 47 to rotate synchronously but in opposite directions. A lifting rod 48 is fixedly connected to the side of the movable block 47 away from the fixed plate 41. The movable block 47 drives the lifting rod 48 to move synchronously. Multiple sets of first suction cups 49 are respectively provided on opposite sides of the two sets of lifting rods 48. When the two sets of lifting rods 48 approach each other, the first suction cups 49 contact the packaging bag, holding the bag opening closed. Thus, when the two sets of lifting rods 48 move away from each other, the bag opening opens. Multiple sets of limiting rods 410 are fixedly connected between the two sets of positioning plates 42. The limiting rods 410 pass through the movable block 47 and slide against it, ensuring smooth movement of the movable block 47.

[0028] Furthermore, such as Figure 4 and Figure 6 As shown, the above-mentioned packaging production line includes a bag-picking mechanism 5 located on one side of the bag-opening assembly 4. The bag-picking mechanism 5 is used to provide packaging bags. The bag-picking mechanism 5 includes a vertical plate 51, and two sets of bag-collecting frames 52 are provided on the side of the vertical plate 51. Multiple sets of support blocks 53 are fixedly connected to the bottom of the two sets of bag-collecting frames 52, and the bag-collecting frames 52 and support blocks 53 are used to temporarily store packaging bags. A fourth push rod 54 is provided below the bag-collecting frame 52, and a lifting plate 55 is fixedly connected to the output end of the fourth push rod 54. Multiple sets of second suction cups 56 are provided on the lifting plate 55. The second suction cups 56 are positioned corresponding to the bag-collecting frame 52. After the fourth push rod 54 extends, it drives the second suction cups 56 to approach the packaging bag. After the second suction cups 56 adsorb the packaging bag, the fourth push rod 54 shortens and removes the bottommost packaging bag.

[0029] For further details, please refer to Figure 1 , Figure 4 , Figure 5 and Figure 6The aforementioned packaging production line includes a clamping assembly 6 located on the side of the bag opening assembly 4 away from the pushing assembly 2. The clamping assembly 6 is equipped with elastic clamping blocks 7 for clamping the packaging bag. The clamping assembly 6 includes two sets of first drive units 61, each with a control end connected to two sets of clamping plates 62. The first drive units 61 drive the clamping plates 62 to move. Each of the two sets of clamping plates 62 has two sets of elastic clamping blocks 7. When the clamping plates 62 approach each other, they clamp the packaging bag through the elastic clamping blocks 7. The clamping assembly 6 also includes a second drive unit 63, with a control end connected to two sets of connecting rods 64. Each of the two sets of connecting rods 64 has a clamping rod 65 fixedly connected to one end. The second drive unit 63 drives the clamping rods 65 to move through the connecting rods 64. Six sets of elastic clamping blocks 7 are symmetrically arranged on both sides of the connecting rods 64. When the clamping rods 65 approach each other, they clamp the packaging bag through the elastic clamping blocks 7. The first drive unit 61 and the second drive unit 63 are used to drive the clamping plate 62 and the connecting rod 64 to open and close. This is existing technology and will not be described in detail here.

[0030] The elastic clamping block 7 includes a T-shaped column 71 that is slidably connected to the clamping plate 62 or the clamping rod 65. One end of the T-shaped column 71 is fixedly connected to the squeezing block 72. A spring 73 is sleeved on the outer ring of the T-shaped column 71. When the two sets of clamping plates 62 or the two sets of clamping rods 65 are close together, the spring 73 is in a compressed state, and the squeezing block 72 is located on both sides of the packaging bag to clamp it.

[0031] like Figure 1 As shown, the packaging production line includes a transfer mechanism 8, which drives the clamping assembly 6 and the elastic clamping block 7 to move. The transfer mechanism 8 includes a fixedly mounted side plate 81. A second linear motor 82 is mounted on the side plate 81 near the clamping assembly 6. The moving end of the second linear motor 82 is fixedly connected to a mounting plate 83, and the second linear motor 82 drives the mounting plate 83 to move. The first drive unit 61 and the second drive unit 63 are both mounted on the side of the mounting plate 83. The mounting plate 83 drives the two sets of first drive units 61 and the set of second drive units 63 to move synchronously. Multiple sets of third sliders 84 are fixedly connected to the side plate 81 of the mounting plate 83. A second slide rail 85 is slidably connected to the multiple sets of third sliders 84. The second slide rail 85 is fixedly connected to the side plate 81. The arrangement of the third sliders 84 and the second slide rail 85 makes the movement of the mounting plate 83 smooth.

[0032] Finally, please see Figure 4The aforementioned packaging production line includes a sealing assembly 9 located on the side of the bag opening assembly 4 away from the bag taking mechanism 5. The sealing assembly 9 is used for heat sealing of the packaging bag opening. The sealing assembly 9 includes two sets of fifth push rods 91 mounted on the frame. The two sets of fifth push rods 91 are arranged opposite each other and respectively fixedly connected to sealing blocks 92. One set of sealing blocks 92 is equipped with an electric heating wire. After the fifth push rods 91 are activated, they drive the two sets of sealing blocks 92 to move closer together to clamp the packaging bag. At the same time, the electric heating wire or electric heating plate is activated to perform heat sealing.

[0033] When the two sets of first drive units 61 activate the bag-grabbing mechanism 5 to remove the packaging bag, the second drive unit 63 simultaneously activates to grip the packaging bag containing the tea cake. When the transfer mechanism 8 moves the two sets of first drive units 61 to the bag-opening assembly 4, the second drive unit 63 moves to the sealing assembly 9. At this time, the bag-opening assembly 4 absorbs the bag gripped by the first drive unit 61 and opens the bag, while the sealing assembly 9 seals the bag gripped by the second drive unit 63. Afterwards, the first drive units 61 and second drive units 63 release their grip on the bag, and the transfer mechanism 8 resets the first drive units 61 and second drive units 63.

[0034] In this embodiment, the irregularly shaped tea cake is first poured into the vibratory feeders 11 of the two sets of discharge mechanisms 1. The vibratory feeders 11 align the tea cakes through vibration and discharge them in an orderly manner to the first conveyor belt 12. The first conveyor belt 12 transports the tea cakes away from the vibratory feeders 11. During this process, the two sets of baffles 15 at the top limit the tea cakes and prevent them from rotating or shifting. When the tea cakes reach the end of the first conveyor belt 12, they slide onto the second conveyor belt 13 below via the inclined plate 14. The second conveyor belt 13 continues to transport the tea cakes to the corresponding positioning position of the pushing component 2. During this process, photoelectric sensors detect the distribution of the tea cakes to ensure a stable conveying rhythm.

[0035] At this time, the bag-retrieving mechanism 5 starts simultaneously. The fourth push rod 54 extends, driving the lifting plate 55 and the second suction cup 56 to rise below the bag collection frame 52. After the second suction cup 56 adsorbs the bottommost packaging bag in the bag collection frame 52, the fourth push rod 54 shortens to complete the bag retrieval. Subsequently, the second linear motor 82 of the transfer mechanism 8 starts, driving the mounting plate 83 to move along the second slide rail 85 to the position of the bag-retrieving mechanism 5. The two sets of first drive units 61 of the clamping assembly 6 move, driving the clamping plate 62 to move closer. The elastic clamping blocks 7 on the clamping plate 62 clamp the two sides of the packaging bag, completing the preparation for the transfer of the packaging bag.

[0036] The transfer mechanism 8 moves the first drive unit 61, which holds the packaging bag, to the position of the bag opening assembly 4, while the second drive unit 63 moves synchronously to the position of the sealing assembly 9. The servo motor 45 of the bag opening assembly 4 starts, driving the bidirectional threaded rod 46 to rotate. Since the threads at both ends of the bidirectional threaded rod 46 are opposite in direction, and the moving block 47 is threadedly connected to the bidirectional threaded rod 46 and limited by the limiting rod 410, the two sets of moving blocks 47 drive the lifting rods 48 to move closer to each other synchronously. When the first suction cup 49 on the lifting rod 48 contacts and clamps the opening of the packaging bag, the servo motor 45 reverses, driving the two sets of lifting rods 48 to move away from each other, thereby opening the opening of the packaging bag.

[0037] Then, the two sets of first push rods 21 of the pushing assembly 2 are activated, driving the push block 23 via the moving frame 22 to push the tea cake at the end of the second conveyor belt 13 towards the push plate 24. One side of the tea cake contacts and is positioned with the limiting part 210 of the push plate 24, while the slot 29 holds one end of the tea cake in place. At this time, the third push rod 39 extends, passing through the synchronization plate 32 to press the tea cake and prevent it from shifting. At the same time as the bag is opened, the opening mechanism 3 is activated, and the second push rod 36 drives the moving plate 31 to move along the first slide rail 27 via the push plate 37, so that the limiting plate 34 and the support plate 35 between the moving plate 31 and the synchronization plate 32 extend into the opened packaging bag opening to prevent the bag opening from closing. Finally, the third push rod 39 shortens and cancels the limiting of the tea cake, and at the same time, the first linear motor 28 is activated, driving the connecting plate 25 and the two sets of push plates 24 to move synchronously, pushing the tea cake smoothly into the packaging bag.

[0038] After the tea cake is placed in the bag, the second drive unit 63 of the clamping assembly 6 activates, driving the clamping rod 65 closer via the connecting rod 64. The elastic clamping block 7 on the clamping rod 65 clamps the packaging bag containing the tea cake. The transfer mechanism 8 moves the second drive unit 63 to the sealing assembly 9. The two sets of fifth push rods 91 of the sealing assembly 9 are activated, causing the sealing blocks 92 to move closer together. The electric heating wire inside one set of sealing blocks 92 heats up, performing heat-sealing on the opening of the packaging bag. After sealing, the first drive unit 61 and the second drive unit 63 release their clamps on the empty bag and the sealed bag, respectively. The transfer mechanism 8 drives the clamping assembly 6 to reset, entering the next packaging cycle.

[0039] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
