Detailed Implementation

[0007] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0008] Reference Figure 1-2 A multifunctional fully automated tea gift box production line includes a vertical storage unit 63 for storing tea raw materials, a tea box circulation conveyor line 200, and a fully automated tea bag blending and packaging equipment 300. The fully automated tea bag blending and packaging equipment 300 is located between the vertical storage unit 63 and the tea box circulation conveyor line 200. A pressure-relief opening mechanism 400 is installed on the side of the vertical storage unit 63 furthest from the fully automated tea bag blending and packaging equipment 300, and a lifting and unloading mechanism 500 is installed on the side of the vertical storage unit 63 closest to the fully automated tea bag blending and packaging equipment 300. The bag blending and packaging equipment 300 has automatic bag picking, filling, and sealing functions, and is used to package blended tea into small bags of tea. The tea box circulation transport line 200 is equipped with a forward and reverse tea bag blowing mechanism 600, a multi-bag tea bag automatic placement mechanism 800, and an automatic lid-opening mechanism 700 for tea boxes. At the end of the tea box circulation transport line 200, a card issuing machine 144, a desiccant dispensing mechanism 145, a label pasting mechanism 146, and a weighing platform 142 are also arranged in sequence. The weighing platform 142 is electrically connected to a third feeding push rod 143.

[0009] When using this production line, the tea storage boxes are opened and closed via a pressure-relief box-opening mechanism 400, allowing different types of tea to be placed into their corresponding coded storage boxes. The storage boxes containing tea are then placed into the vertical storage unit 63 by an external robotic arm. The external robotic arm then removes the required tea storage boxes and places them onto a lifting and unloading mechanism 500. The lifting and unloading mechanism 500 feeds the tea into the fully automatic tea bag blending and packaging equipment 300, where the bag-taking, filling, and sealing processes are completed, transforming loose tea into bagged tea. After the tea bags are packaged, they are transported to various processing stages by a tea box circulation transport line 200.

[0010] During the conveying process, all bagged tea first passes through the forward and reverse tea bag blowing mechanism 600. This mechanism adjusts the tea bags so that their front and back faces the same direction, ensuring uniform orientation. After unifying the orientation, the bagged tea undergoes dual-line production. In the first line, the bagged tea is conveyed to the automatic lid-opening mechanism 700 for tea boxes. This mechanism controls the opening and closing of the pull-out tea boxes, inserting two bags of tea into each box when it opens, thus achieving two-bag tea packaging. After packaging, the tea box circulation transport line 200 conveys the tea to the final stacking stage. In the second line, the uniformly oriented bagged tea is conveyed to the multi-bag tea automatic placement mechanism 800. This mechanism adjusts all the bagged tea into a side-standing position, with pairs of tea bags adjacent to each other. Then, an appropriate quantity of these bags is selected and placed into medium-sized tea boxes, completing the multi-bag tea packaging process. Medium-sized tea boxes are continuously conveyed by a tea box circulation conveyor line 200. During the conveying process, medium-sized tea boxes are filled into large-sized tea boxes. During the filling process, a card issuing machine 144 and a desiccant dispensing mechanism 145 insert product cards and desiccant into the large-sized tea boxes, and a label affixing mechanism 146 affixes labels to the large-sized tea boxes. Finally, the packaged large tea boxes are weighed by a weighing platform 142, and the weighing data is fed back to the system. When the weighing data meets the standard, the large tea box is conveyed to the palletizing stage; if it does not meet the standard, a third feeding pusher 143 pushes the large tea box off the conveyor line, thereby achieving precise control over the quality of the packaged tea boxes.

[0011] Reference Figure 3-5 In this embodiment, the pressure relief box opening mechanism 400 includes a second mounting frame 53 disposed at one end in the vertical storage 63, a first placement platform 54 disposed at the lower part of the second mounting frame 53 for placing the tea storage box, and a third connecting plate 64 disposed at the upper part of the second mounting frame 53, and a pressure relief mechanism disposed on the third connecting plate 64. The pressure relief mechanism includes several seventh cylinders 55 disposed on the lower wall of the third connecting plate 64. The output ends of the several seventh cylinders 55 are connected to the same suction cup plate 56. The middle part of the suction cup plate 56 is hollow. A liftable pressure relief suction cup 57 is disposed on the suction cup plate 56. The pressure relief suction cup 57 passes through the hollow part of the suction cup plate 56 and is located below the suction cup plate 56. A third clamping mechanism 58 is disposed on the suction cup plate 56. The third clamping mechanism 58 is used for fixing the tea storage box.

[0012] When using this device, the tea storage box is first placed on the first placement platform 54. The pressure relief suction cup 57 moves downwards until it contacts the top of the tea storage box, and the pressure relief valve on the storage box is opened to release the negative pressure inside the storage box. Then, several seventh cylinders 55 are controlled to move the suction cup plate 56 downwards until it contacts the tea storage box and sucks the lid in place. The seventh cylinders 55 are then controlled to move the lid upwards simultaneously, thus opening the lid. The staff then put an appropriate amount of tea into the tea storage box. After the tea is put in, the seventh cylinders 55 move the lid downwards and securely close the lid on the tea storage box, thus completing the tea storage process.

[0013] Reference Figure 5 The suction cup plate 56 is provided with a third clamping mechanism 58, which is used to fix the tea storage box, thereby preventing the suction cup plate 56 and the pressure relief suction cup 57 from sucking the entire tea storage box during the pressure relief process, thus affecting the normal opening of the lid.

[0014] Reference Figure 5 A weighing sensor is installed on the first placement platform 54. The weighing sensor detects the net weight of the tea storage box and the weight of the tea leaves added, thereby standardizing the storage amount of tea leaves in several tea storage boxes.

[0015] Reference Figure 4-5 In this embodiment, a first moving mechanism 59 is provided at the lower part of the second mounting frame 53. One end of the first moving mechanism 59 is located on the outside of the second mounting frame 53. The first placement platform 54 is driven by the first moving mechanism 59 to move the second mounting frame 53 in the front and back direction, so that the first moving mechanism 59 can drive the first placement platform 54 to move to the front of the second mounting frame 53, so that the tea storage box after opening can move synchronously to the outside of the second mounting frame 53. During this movement, the third clamping mechanism 58 releases the fixation of the tea storage box body, so that the first placement platform 54 can drive the tea storage box to move synchronously to the outside of the second mounting frame 53, thereby providing convenience for manual tea feeding.

[0016] Reference Figure 5 A second moving mechanism 60 is provided on the moving end of the first moving mechanism 59. The second moving mechanism 60 is used to control the first placement platform 54 to move left and right along the second mounting frame 53. The second moving mechanism 60 facilitates the left and right movement and adjustment of the position of the first placement platform 54 on the second mounting frame 53, so that the tea storage box can be directly facing the suction cup plate 56, which facilitates the depressurization and opening of the tea storage box.

[0017] Reference Figure 4A third moving mechanism 61 is provided on the top of the second mounting frame 53. The third moving mechanism 61 controls the pressure relief mechanism to move back and forth along the second mounting frame 53. A fifth conveyor belt 62 is provided on the side of the second mounting frame 53 away from the first moving mechanism 59. After tea is put into the tea storage box, it can be moved by the third moving mechanism 61 to the fifth conveyor belt 62 for unified transportation, thereby improving the transportation efficiency.

[0018] Reference Figure 1 The vertical storage unit 63 is equipped with several storage compartments for storing tea storage boxes and a movable robotic arm. The fifth conveyor belt 62 runs through the entire vertical storage unit 63, so that the movable robotic arm can place the tea storage boxes on the fifth conveyor belt 62 into the storage compartments on the vertical storage unit 63, thereby achieving rapid storage of the tea storage boxes. Reference Figure 1 , 6 7. The lifting and unloading mechanism 500 includes a third mounting frame 65 and a fourth mounting frame 66 disposed between the vertical storage 63 and the fully automatic tea bag blending and packaging equipment 300. The third mounting frame 65 is provided with a first hopper 67 and a second placement platform 68. The bottom of the second placement platform 68 is connected to a first drive shaft 69, which is driven by a first motor 70 mounted on the third mounting frame 65. The fourth mounting frame 66 is provided with a drive belt 71, which is connected to several second hoppers 72. A transverse conveyor belt 73 is provided on the outside of the fourth mounting frame 66. One end of the transverse conveyor belt 73 is located at the fourth mounting frame 66, and the other end is located at and above the blending device. A third hopper 74 is connected to the transverse conveyor belt 73, and the height of the third hopper 74 is lower than the height of the top of the drive belt 71.

[0019] When the mechanism is in operation, a robotic arm places the tea storage box on the second placement platform 68. The first motor 70 drives the first transmission shaft 69 to rotate, thereby causing the second placement platform 68 to tilt inward into the first hopper 67, so that the tea in the tea storage box is poured into the first hopper 67 and flows from the first hopper 67 into the second hopper 72. Then, the transmission belt 71 drives several parallel second hoppers 72 to be lifted above the third hopper 74, and the tea in the second hoppers 72 is put into the third hopper 74. Then, the transverse conveyor belt 73 drives the third hopper 74 to the blending device, and puts the tea into the blending device, thus completing the feeding operation into the blending device.

[0020] Reference Figure 6In this embodiment, a fourth clamping mechanism 75 is provided on the second placement platform 68. The fourth clamping mechanism 75 is used to fix the tea storage box placed on the second placement platform 68, thereby preventing the tea storage box from falling into the first hopper 67.

[0021] Reference Figure 6 In this embodiment, a pressure relief mechanism is provided on the third mounting frame 65. The pressure relief mechanism is located above the second placement platform 68 so that the tea storage box can be depressurized and opened before the tea is poured into the first hopper 67, and the lid can be suctioned so that the tea can be poured from the tea storage box into the first hopper 67.

[0022] Reference Figure 7 In this embodiment, the bottom of the third hopper 74 and several second hoppers 72 are all provided with an opening and closing mechanism 76. The opening and closing mechanism 76 controls the feeding situation of the second hoppers 72 and the third hopper 74, so that the second hoppers 72 and the third hopper 74 move to a specific position for feeding.

[0023] Reference Figure 7 In this embodiment, a U-shaped connecting plate 77 is provided on the fourth mounting frame 66, and a fourth moving mechanism 78 is provided on the U-shaped connecting plate 77. The fourth moving mechanism 78 is used to control a plurality of second hoppers 72 to move horizontally, so as to control the plurality of second hoppers 72 to move to an appropriate position according to the material receiving and discharging situation in the second hoppers 72, so as to replace the second hoppers 72 that are receiving or discharging materials.

[0024] Reference Figure 7 In this embodiment, the first hopper 67 has a notch on the side near the vertical storage tank 63. Part of the second placement platform 68 is located inside the first hopper 67 through the notch, so that when the first motor 70 drives the second placement platform 68 to rotate, the tea in the tea storage box placed on the second placement platform 68 can be poured into the first hopper 67, avoiding the tea falling outside the first hopper 67 and causing tea loss.

[0025] Reference Figure 8-10The fully automatic tea bag blending and packaging equipment 300 is equipped with a housing 79 and an L-shaped device plate 80 inside the housing 79. Three first assembly hoppers 81 are arranged in parallel between the top of the housing 79 and the L-shaped device plate 80. The first assembly hoppers 81 are connected to the top of the L-shaped device plate 80 via a vibration assembly. Three circular vibrating discs 88 are arranged side-by-side on the top of the L-shaped device plate 80. The discharge ports of the three first assembly hoppers 81 correspond one-to-one with the inlets of the circular vibrating discs 88. Weighing modules are installed at the discharge ports of the three circular vibrating discs 88. Second assembly hoppers 82 and third assembly hoppers 83 are respectively arranged on the two side walls of the L-shaped device plate 80. The second-stage hopper 82 is used to transport tea leaves from the circular vibrating plate 88 to the third-stage hopper 83. The L-shaped device plate 80 is equipped with a storage mechanism 84 for storing tea bags and a linkage suction cup bag opening mechanism 85. Below the linkage suction cup bag opening mechanism 85 are a tea bag bottom folding mechanism 86 and a multi-functional tea bag sealing mechanism 87. The multi-functional tea bag sealing mechanism 87 is located below the tea bag bottom folding mechanism 86. The L-shaped device plate 80 is equipped with a feeding mechanism 89 and a laser mechanism 90. The feeding mechanism 89, the third-stage hopper 83 and the multi-functional tea bag sealing mechanism 87 are on the same horizontal line, and the laser mechanism 90 is located outside the horizontal line.

[0026] In use, different types of tea are fed into different first assembly hoppers 81. The first assembly hopper 81, under the action of a vibrating component, transports the tea to a circular vibrating plate 88. The tea is weighed by a weighing module on the circular vibrating plate 88. After weighing, a specific amount of tea is fed into a second assembly hopper 82, which then transfers the tea to a third assembly hopper 83. Finally, a linkage-type suction cup bag-opening mechanism 85 removes the tea bag from the storage mechanism 84, and a bottom-folding mechanism 86 folds the bottom edge of the tea bag. The tea bag is folded, and then the tea bag is opened and filled by the coordinated operation of the linkage suction cup opening mechanism 85 and the third assembly hopper 83. At the same time, the tea bag is laser-coded by the laser mechanism 90 to facilitate the traceability of the product source and the verification of authenticity. Then, the unloading mechanism 89 pushes the filled tea bag downwards so that the tea bag falls into the multi-functional tea bag sealing mechanism 87. The multi-functional tea bag sealing mechanism 87 seals the filled tea bag, thus realizing the whole process of tea blending and packaging.

[0027] Reference Figure 9 , Figure 4 , Figure 5In this embodiment, the storage mechanism 84 includes a fourth connecting plate 841 mounted on an L-shaped device plate 80. One end of the fourth connecting plate 841 is fixedly connected to a first cylindrical plate 842, and the other end is slidably connected to a second cylindrical plate 843 in the horizontal direction. A first rack 844 is connected to the second cylindrical plate 843, and a first gear 845 is meshed on the first rack 844. The first gear 845 is driven by a first servo motor 846, which is mounted on the top of the fourth connecting plate 841.

[0028] When the first servo motor 846 drives the first gear 845 to rotate, it can drive the first rack 844 to move the second cylinder plate 843 back and forth in the horizontal direction, thereby realizing the adjustment and control of the distance between the first cylinder plate 842 and the second cylinder plate 843, so that the storage mechanism 84 can meet the storage work of tea bags of different heights and improve the adaptability of the storage mechanism 84.

[0029] Reference Figure 9 , Figure 13-15 In this embodiment, the linkage suction cup bag opening mechanism 85 includes a positioning suction cup 91 disposed at the lower end of the feeding mechanism 89, a storage mechanism 84 disposed on the L-shaped device plate 80 for placing tea bags, and a gripping mechanism. The gripping mechanism includes a sixth connecting plate 99 mounted on the L-shaped device plate 80, a seventh connecting plate 100 disposed on the sixth connecting plate 99, an L-shaped connecting groove 111 extending through the L-shaped device plate 80, the sixth connecting plate 99, and the seventh connecting plate 100, and an incomplete gear 101 disposed on the seventh connecting plate 101, with a third gear 102 meshing on the incomplete gear 101. Gear 102 is driven by third servo motor 103. A first connecting rod 104 is installed on the incomplete gear 101. A second drive shaft 105 is slidably connected to the first connecting rod 104. The second drive shaft 105 passes through the L-shaped device plate 80 via the L-shaped connecting groove 111 and is connected to the second connecting rod 106. A second suction cup 107 is connected to the second connecting rod 106. A first connecting block 108 is rotatably connected to the sixth connecting plate 99 via bearings. Two first slide rods 109 are provided on the first connecting block 108. The second drive shaft 105 is slidably connected to the two first slide rods 109 via the second connecting block 110.

[0030] When it is necessary to grab tea bags, the grabbing mechanism operates first. The third servo motor 103 drives the third gear 102 to rotate, which in turn drives the incomplete gear 101 to rotate. The incomplete gear 101 then drives the first connecting rod 104 to move synchronously. The first connecting rod 104 then drives the second drive shaft 105, the second connecting rod 106, and the second suction cup 107 to move along the path of the L-shaped connecting groove 111 towards the storage mechanism 84. While the first connecting rod 104 drives the second drive shaft 105 to move, the second connecting block 110 slides on the two first sliding rods 109. With the continuous rotation of the incomplete gear 101, when the first connecting rod 104 rotates to the corner of the L-shaped connecting groove 111, the connection between the second connecting block 110 and the first sliding rod 109 drives the first connecting block 108 to rotate. At this time, the first connecting block 108 rotates the two first sliding rods 109 and the components mounted on the first sliding rods 109 around the bearing, causing the first sliding rods 109 to change from a horizontal to a vertical state, thereby causing the angle of the second connecting rod 106 to change by 90°. When the second connecting rod 106 is in a vertical state, the second suction cup 107 picks up the tea bag in the storage mechanism 84; when the second connecting rod 106 is in a horizontal state, the second suction cup 107 and the tea bag it has picked up can move to the positioning suction cup 91. By working synchronously with the second suction cup 107, the positioning suction cup 91 picks up both sides of the tea bag, and the movement of the second connecting rod 106 drives the second suction cup 107 to move synchronously, thus opening the tea bag.

[0031] Reference Figure 14 The first connecting rod 104 has a first connecting groove 112. The second drive shaft 105 is slidably connected to the first connecting groove 112 through a bearing. The length of the first connecting groove 112 is greater than the diameter of the bearing, so that the second drive shaft 105 can be slidably connected to the first connecting rod 104 through the first connecting groove 112, thereby realizing the purpose of the second drive shaft 105 moving along the path of the L-shaped connecting groove 111.

[0032] Reference Figure 16 An adjustment plate 113 is provided on the second suction cup 107, and a third suction cup 114 is slidably mounted on the adjustment plate 113. The distance between the third suction cup 114 and the second suction cup 107 can be controlled by manual adjustment. The two suction cups make the gripping mechanism grip the tea bag more securely, and the adjustable distance between the two suction cups makes it easy for the gripping mechanism to grip tea bags of different lengths.

[0033] Reference Figure 13An eighth connecting plate 115 is mounted on the seventh connecting plate 100. The body of the third servo motor 103 is mounted on the eighth connecting plate 115. The incomplete gear 101 is connected between the seventh connecting plate 100 and the eighth connecting plate 115 through a bearing, so as to provide a stable connection between the third servo motor 103 and the incomplete gear 101.

[0034] Reference Figure 9 , Figure 17 In this embodiment, the bottom folding mechanism 86 of the tea bag includes a fourth connecting plate 92 disposed on the L-shaped device plate 80. The fourth connecting plate 92 is provided with a second lifting mechanism 93 and a relative motion mechanism 94. The second lifting mechanism 93 is used to drive the relative motion mechanism 94 to move vertically up and down. The moving end of the relative motion mechanism 94 is connected to two folding plates 95. The edges of the two folding plates 95 that are close to each other are staggered and located directly below the two positioning suction cups 91.

[0035] When in use, the mechanism uses two positioning suction cups 91 to adhere and fix the tea bag to both sides, so that the tea bag is between two folding plates 95. Then, the relative motion mechanism 94 runs, which drives the two folding plates 95 to move closer to each other, thereby forming a clamping force on the tea bag. Through the staggered arrangement of the two folding plates 95, the bottom edge of the tea bag is bent. Then, the relative motion mechanism 94 controls the two folding plates 95 to move away, thereby relieving the force exerted by the folding plates 95 on the tea bag. The second lifting mechanism 93 then moves the relative motion mechanism 94 and the folding plates 95 to the bottom of the tea bag. At this point, the two folding plates 95 are brought into contact with each other to form a plane, so that the bottom edge of the folded tea bag is on this plane. The second lifting mechanism 93 then moves the folding plates 95 vertically back and forth, causing the plane to move up and down. When moving upward, the plane contacts the bottom folded edge of the tea bag, thus performing an upward lifting operation on the tea bag. Through multiple upward lifting actions, the creases of the tea bag's edge are deepened, thereby changing the bottom folded edge of the tea bag from a vertical state to a stable horizontal folded edge, further improving the stability of the folded edge.

[0036] Reference Figure 17-18 The second lifting mechanism 93 includes a first servo motor 931 mounted on the fourth connecting plate 92. A first gear 932 is connected to the output shaft of the first servo motor 931. A first rack 933 meshes with the first gear 932. The first rack 933 is slidably connected to the fourth connecting plate 92 via a first slide rail 934. The first rack 933 is connected to the relative motion mechanism 94.

[0037] The first servo motor 931 drives the first gear 932 to rotate, thereby driving the first rack 933 to move up and down on the fourth connecting plate 92 in the vertical direction via the first slide rail 934, which in turn drives the relative motion mechanism 94 to move synchronously, thereby achieving the purpose of controlling the height of the relative motion mechanism 94.

[0038] Reference Figures 19-20 The relative motion mechanism 94 includes a fifth connecting plate 941 connected to the moving end of the second lifting mechanism 93. A second servo motor 942 is mounted on the fifth connecting plate 941, and a second gear 943 is connected to the output shaft of the second servo motor 942. Two second racks 944 mesh with each other on both sides of the second gear 943. Each of the two second racks 944 has a first sliding groove 945, which is connected to one of the two folding plates 95. When the relative motion mechanism 94 is running, the second servo motor 942 drives the second gear 943 to rotate, thereby driving the two second racks 944 to move closer or further apart, thus achieving the purpose of moving the two folding plates 95 closer or further apart through the second racks 944. When the two folding plates 95 move closer together, they clamp the bottom edge of the tea bag, and fold the bottom edge of the tea bag during the process of the folding plates 95 moving closer. When the two folding plates 95 move further apart, the folding plates 95 release the restriction on the position of the tea bag.

[0039] Reference Figure 20 The bottom of the fifth connecting plate 941 is provided with a second slide rail 946. Both first slide grooves 945 are slidably connected to the second slide rail 946 so that the movement direction of the two second racks 944 can be restricted by the setting of the second slide rail 946, so that they can only move in the horizontal direction, thereby achieving the effect of the two being able to move closer or further apart.

[0040] Reference Figure 19 The fourth connecting plate 92 and the fifth connecting plate 941 are each provided with a first distance sensor 96, and the fourth connecting plate 92 and the second rack 944 are each provided with a first detection piece 97. The first distance sensor 96 acts on the corresponding first detection piece 97.

[0041] By sensing the position of the first detection piece 97 through the first distance sensor 96, the movement distance of the relative motion mechanism 94 and the second lifting mechanism 93 is controlled, thereby improving the stability of each mechanism during operation.

[0042] Reference Figure 17Each of the two folding plates 95 is equipped with a limiting plate 98, which allows the two limiting plates 98 and the two folding plates 95 to form a stable space. This allows the limiting plates 98 to restrict the thickness of the tea bags after tea leaves are placed inside, thus ensuring a uniform thickness across all tea bags.

[0043] Reference Figure 9 , Figure 21 , Figure 22 In this embodiment, the feeding mechanism 89 includes a ninth connecting plate 891 mounted on an L-shaped device plate 80. The ninth connecting plate 891 and the L-shaped device plate 80 are connected by the same tenth connecting plate 892. A fourth synchronous belt 893 is provided on the tenth connecting plate 892. A second feeding push rod 894 is connected to the fourth synchronous belt 893. The second feeding push rod 894 can reciprocate in the vertical direction and is directly opposite the third assembly hopper 83.

[0044] When the feeding mechanism 89 is running, the tea bag opens its mouth and is fixed in position by the positioning suction cup 91, the second suction cup 107, and the third suction cup 114, so that the discharge port of the third assembly hopper 83 is inserted into the tea bag. The second feeding push rod 894 is driven to move back and forth in the vertical direction by the fourth synchronous belt 893. When the second feeding push rod 894 moves downward, it is inserted into the third assembly hopper 83 and the tea bag. During the continuous downward movement of the second feeding push rod 894, the tea bag is pushed down and falls into the multi-functional tea bag sealing mechanism 87 for sealing.

[0045] Reference Figure 21 In this embodiment, the discharge port of the third assembly hopper 83 is rotatably connected to both sides of the opening and closing plate 895. When the bottom ends of the two opening and closing plates 895 are in contact, the discharge port of the third assembly hopper 83 is in a closed state. The tenth connecting plate 892 is provided with a ninth cylinder 896. The output shaft of the ninth cylinder 896 is connected to a U-shaped connecting rod 897. Rotating wheels 898 are provided on both sides of the U-shaped connecting rod 897. The two rotating wheels 898 are located on the outside of the two opening and closing plates 895.

[0046] When the ninth cylinder 896 is running, it drives the U-shaped connecting rod 897 to reciprocate vertically. When the U-shaped connecting rod 897 moves upward, it drives the two rotating wheels 898 to move upward synchronously, so that the rotating wheels 898 contact the upper part of the opening and closing plate 895, so that the upper parts of the two opening and closing plates 895 are close to each other and the lower parts are far apart, thereby forming a channel connected to the discharge port of the third assembly hopper 83, so as to put the tea leaves in the third assembly hopper 83 into the tea bag; when the U-shaped connecting rod 897 moves downward, the two rotating wheels 898 do not contact the opening and closing plate 895, and the two opening and closing plates 895 contact the discharge port of the third assembly hopper 83, so that the discharge port is in a closed state, thereby preventing tea leakage.

[0047] Reference Figure 22 In this embodiment, a fifth synchronous belt 899 is provided on the tenth connecting plate 892. The fifth synchronous belt 899 is used to drive the third assembly hopper 83 to move vertically, so that when the tea bags are unloaded and empty tea bags need to be replenished, the third assembly hopper 83 can be driven upward by the fifth synchronous belt 899, thereby providing sufficient space for the operation of the linkage suction cup bag opening mechanism 85.

[0048] Reference Figure 9 , Figure 23 , 24 In this embodiment, the multifunctional tea bag sealing mechanism 87 includes a first template 116 and a second template 117 disposed on an L-shaped device plate 80. A pressing plate 122 is slidably disposed between the first template 116 and the second template 117. A support plate 123 and a heating plate 124 are disposed between the first template 116 and the pressing plate 122. The heating plate 124 is located above the support plate 123 and is disposed inside the pressing plate 122. A fourth [other component] is installed on the outside of the second template 117. Servo motor 118, the output shaft of the fourth servo motor 118 is connected to a fourth gear 119, the fourth gear 119 is meshed with a bidirectional rack 120, one end of the bidirectional rack 120 is elastically connected to a first sliding block 121, the first sliding block 121 is used to drive the heating plate 124 to move, the bidirectional rack 120 is meshed with a coaxial double gear 125, the bottom gear of the coaxial double gear 125 is meshed with a third rack 126, the end of the third rack 126 is elastically connected to the pressing plate 122.

[0049] When sealing the tea bag, the tea bag to be sealed is placed on the tray 123. The fourth servo motor 118 is started, which drives the fourth gear 119 to rotate, thereby driving the bidirectional rack 120 to move synchronously. When the bidirectional rack 120 moves, it drives the coaxial double gear 125 to rotate, thereby driving the third rack 126 to move synchronously. The bidirectional rack 120 and the third rack 126 respectively drive the heating plate 124 and the pressing plate 122 to move towards the tea bag. When the pressing plate 122 moves to contact the first template 116, it performs vacuuming on the tea bag; when the heating plate 124 moves to contact the top of the tea bag, it heats and seals the vacuumed tea bag, thus achieving synchronous vacuuming and sealing of the tea bag during the operation of the mechanism.

[0050] Reference Figure 23 , 26 A first spring 137 is provided between the bidirectional rack 120 and the first sliding block 121, and a second spring 138 is provided between the third rack 126 and the pressing plate 122. The length of the second spring 138 is longer than that of the first spring 137. By differentiating the lengths of the first spring 137 and the second spring 138, during the movement of the bidirectional rack 120 and the third rack 126, after the third rack 126 drives the pressing plate 122 to contact the first template 116, the first spring 137 will be compressed by the thrust as the third rack 126 continues to move towards the first template 116. This achieves the effect of the third rack 126 continuously outputting while the pressing plate 122 remains stationary. Simultaneously, the bidirectional rack 120 and the third rack 126 move synchronously with the same stroke. When the third rack 126 pushes the first spring 137 to compress, the bidirectional rack 120 continues to drive the first sliding block 121 and the heating plate 124 to move through the second spring 138. This achieves the operation of heat sealing after the pressing plate 122 contacts the first template 116 and then the heating plate 124 contacts the tea bag.

[0051] Reference Figure 25 A scraping mechanism is provided between the first template 116 and the pressing plate 122. The scraping mechanism includes a third slide rail 128 disposed inside the pressing plate 122. A first scraper 129 is slidably connected to the third slide rail 128. A second scraper 131 is coaxially connected to the first scraper 129. The second scraper 131 is slidably connected to the first template 116. A first synchronous belt 130 is provided on the back of the first template 116. The second scraper 131 moves vertically through the transmission of the first synchronous belt 130.

[0052] The scraping operation is performed before sealing the tea bags. During scraping, the pressing plate 122 moves towards the first template 116, causing the first scraper 129, connected to the pressing plate 122 via the third slide rail 128, to move towards the second scraper 131. This ensures that the two sides of the tea bag are tightly pressed between the first scraper 129 and the second scraper 131. Then, the first synchronous belt 130 drives the second scraper 131 to move downwards vertically. The first scraper 129 moves downwards synchronously through its coaxial connection with the second scraper 131 and its sliding connection with the third slide rail 128. This allows the first scraper 129 and the second scraper 131 to move downwards synchronously while maintaining contact with both sides of the tea bag, thereby scraping the tea leaves inside the tea bag to the bottom of the tea bag, making the tea leaves inside into a tofu-like shape. This ensures that the tea leaves in all tea bags have a uniform shape, facilitating subsequent packaging work.

[0053] Reference Figure 24 , 25A third drive shaft 132 is provided on the outer side of the pressing plate 122. A connecting rod-shaped irregular spring 133 is provided at one end of the third drive shaft 132. The tilt angle of the connecting rod-shaped irregular spring 133 can be manually adjusted. A fifth gear 134 is provided at the other end of the third drive shaft 132. A fourth rack 135 meshes on the fifth gear 134. The fourth rack 135 is connected to a first connecting shaft 127 through a connecting component. The first connecting shaft 127 is slidably connected to the pressing plate 122 and connected to the third slide rail 128.

[0054] When the tilt angle of the connecting rod-shaped irregular spring 133 is manually adjusted, the connecting rod-shaped irregular spring 133 drives the fifth gear 134 to rotate through the third transmission shaft 132, thereby pushing the fourth rack 135 to move. This causes the first connecting shaft 127, the third slide rail 128 and the first scraper 129 to move synchronously, thereby achieving fine adjustment of the distance between the first scraper 129 and the second scraper 131. This adjusts the clamping force of the first scraper 129 and the second scraper 131 on the tea bag, so that the clamping force is always kept within the standard range. This avoids the situation where the clamping force is too tight, making it difficult for the first scraper 129 and the second scraper 131 to move downwards in the tea bag, and the situation where the clamping force is too loose, making it difficult to scrape all the tea leaves to the bottom of the tea bag.

[0055] Reference Figure 25 The first template 116 has a second synchronous belt 136 on both sides. The tray 123 is connected to the second synchronous belt 136 through a connecting component. When the second synchronous belt 136 is running, it can drive the tray 123 to move up and down synchronously in the vertical direction, thereby achieving the purpose of adjusting the height of the tray 123 to meet the packaging requirements of tea bags of different heights.

[0056] Reference Figure 26 An L-shaped support plate 139 is provided on the L-shaped device plate 80. The short plate of the L-shaped support plate 139 is connected to the L-shaped device plate 80. A third synchronous belt 140 is provided on the long plate of the L-shaped support plate 139. A first feeding push rod 141 is provided on the third synchronous belt 140. The first feeding push rod 141 moves back and forth in the horizontal direction and is on the same horizontal line as the pallet 123. After the tea bag is sealed, it can be driven by the operation of the third synchronous belt 140 to move the first feeding push rod 141 towards the pallet 123 and push the tea bag off the pallet 123, thereby realizing the automated feeding operation.

[0057] Reference Figure 27-29The tea box circulation transport line 200 includes a first conveyor belt 1 for transporting bagged tea that has been packaged. Below the first conveyor belt 1 are a second conveyor belt 8 and a sixth conveyor belt 37. The second conveyor belt 8 and the sixth conveyor belt 37 have the same transport direction and are both perpendicular to the first conveyor belt 1. They are used for transporting small tea boxes and medium-sized tea boxes, respectively. At the end of the second conveyor belt 8 and the sixth conveyor belt 37 is the same third conveyor belt 18. The third conveyor belt 18 is parallel to the rear end of the first conveyor belt 1. A seventh conveyor belt 38 is arranged between the third conveyor belt 18 and the first conveyor belt 1. The seventh conveyor belt 38 is used for transporting large tea boxes.

[0058] During operation, the packaged tea bags are transported via the first conveyor belt 1 to the starting points of the second and sixth conveyor belts 8 and 37, respectively. The tea bags are then placed into small tea boxes on the second conveyor belt 8 and medium-sized tea boxes on the sixth conveyor belt 37. These small and medium-sized tea boxes are then transported to the third conveyor belt 18, where they are further conveyed to the packaging stage. Simultaneously, the medium-sized tea boxes on the third conveyor belt 18 are transferred to large tea boxes transported on the seventh conveyor belt 38, completing the process of placing the medium-sized tea boxes into the large tea boxes. Finally, the seventh conveyor belt 38 transports the filled large packaging boxes to the next stage for subsequent sealing and packaging. This conveyor line, through strategic positioning and functional planning of each conveyor belt, achieves coordinated production processes and efficient material flow for small, medium, and large tea boxes within a limited space, ultimately enabling multi-functional packaging.

[0059] Reference Figure 27 In this embodiment, the first conveyor belt 1 is L-shaped with an arc at its corner. The second conveyor belt 8 and the sixth conveyor belt 37 are located within the planar space formed by the two ends of the first conveyor belt 1. The starting ends of the seventh conveyor belt 38 and the third conveyor belt 18 are located within this planar space. This achieves a dense and orderly distribution of multiple conveyor belts within the effective space, effectively reducing the site area requirements of existing conveyor lines.

[0060] Reference Figure 1 In this embodiment, supplementary conveyor belts 40 are provided at the starting ends of the second conveyor belt 8, the sixth conveyor belt 37 and the seventh conveyor belt 38. The three supplementary conveyor belts 40 are used for replenishing small tea boxes, medium tea boxes and large tea boxes respectively, so as to replenish tea boxes of various sizes on the conveyor line in a timely manner during the entire tea packaging process, thereby avoiding the situation of tea box shortage.

[0061] Reference Figure 27In this embodiment, each of the three supplementary conveyor belts 40 is provided with a fourth electric push rod 39, which is used to push the tea boxes of various sizes on the supplementary conveyor belts 40 to the corresponding conveyor belts, so as to effectively replenish the tea boxes by pushing the tea boxes on each supplementary conveyor belt 40 to the corresponding conveyor belts through the fourth electric push rod 39.

[0062] Reference Figure 27 In this embodiment, a second robotic arm 9 is provided at the junction of the first conveyor belt 1 and the second conveyor belt 8, a first robotic arm 7 is provided at the junction of the first conveyor belt 1 and the sixth conveyor belt 37, and a third robotic arm 43 is provided between the third conveyor belt 18 and the seventh conveyor belt 38. This allows the second robotic arm 9 and the first robotic arm 7 to grab the bagged tea and put it into medium-sized tea boxes and small tea boxes respectively. The third robotic arm 43 then puts the filled medium-sized tea boxes into large tea boxes, thus realizing the transfer between bagged tea and small and medium-sized tea boxes, and the transfer between medium-sized tea boxes and large tea boxes.

[0063] Reference Figure 27 , Figure 29 In this embodiment, a fifth mounting frame 44 is provided on the outer side of the seventh conveyor belt 38. Both ends of the fifth mounting frame 44 are provided with clamping mechanisms. A lid conveyor belt 45 is provided at the bottom of the fifth mounting frame 44. Both ends of the lid conveyor belt 45 are exposed outside the fifth mounting frame 44 so that when a large tea box is conveyed to the position of the fifth mounting frame 44, the lid of the tea box can be sucked up by the clamping mechanism at one end of the fifth mounting frame 44, removed from the tea box and placed on the lid conveyor belt 45, so as to put a medium-sized tea box into the large tea box. When the lid is conveyed to the other end of the lid conveyor belt 45, the lid is sucked up by another clamping mechanism and placed on the large tea box, thereby realizing the opening and closing of the large tea box.

[0064] Reference Figure 29 In this embodiment, the clamping mechanism includes a lateral moving mechanism 46 mounted on the fifth mounting bracket 44. A vertical moving mechanism 47 is drivenly connected to the lateral moving mechanism 46, and a fifth clamping mechanism 48 is provided at the moving end of the vertical moving mechanism 47. The lateral moving mechanism 46 can drive the vertical moving mechanism 47 and the fifth clamping mechanism 48 to move directly above the seventh conveyor belt 38. Then, the vertical moving mechanism 47 drives the fifth clamping mechanism 48 to move downward, so that the fifth clamping mechanism 48 can clamp the lid of the large tea box. Afterwards, the lid is placed on the lid conveyor belt 45 for conveying through the coordinated operation of the lateral moving mechanism 46 and the vertical moving mechanism 47, and then the lid is closed on the large tea box.

[0065] Reference Figure 30-32The multi-bag tea bag automatic placement mechanism 800 includes a first vision recognition mechanism 2, an adjustment mechanism 3, and a pushing mechanism 4 sequentially arranged on a first conveyor belt 1. A merging mechanism 5 is arranged below the pushing mechanism 4 on the first conveyor belt 1. A device plate 6 is arranged on the outside of the merging mechanism 5. The device plate 6 is perpendicular to the first conveyor belt 1. A first robotic arm 7 is arranged on one side of the first conveyor belt 1. The first robotic arm 7 is used to transfer the tea bags placed at the merging mechanism 5 to the tea boxes on the device plate 6.

[0066] When in use, several tea bags are laid flat on the first conveyor belt 1. The first conveyor belt 1 transports the tea bags towards the first visual recognition mechanism 2. During the transport, the first visual recognition mechanism 2 takes pictures of the tea bags to identify their orientation. The orientation information of the tea bags is then transmitted to the control system. The control system controls the adjustment mechanism 3 to adjust the orientation of the tea bags so that each pair of adjacent tea bags is facing each other. After adjustment, the first conveyor belt 1 moves the adjusted tea bags to the pushing mechanism 4. The pushing mechanism 4 pushes two adjacent tea bags one by one from the first conveyor belt 1 onto the device plate 6. During the operation of the pushing mechanism 4, the flat position of the tea bags on the first conveyor belt 1 is adjusted to a side-standing position on the device plate 6. Then, the merging mechanism 5 moves the two tea bags together with their heads and tails facing each other. Finally, the first robotic arm 7 picks up the two side-standing tea bags and puts them into a tea box for packaging.

[0067] Reference Figure 32 The adjustment mechanism 3 includes a frame 31 mounted on the first conveyor belt 1. A rotary motor 32 is located at the center of the frame 31. A first cylinder 33 is connected to the output end of the rotary motor 32, and a first clamping mechanism 34 is connected to the output end of the first cylinder 33. When the adjustment mechanism 3 is running, the first cylinder 33 controls the first clamping mechanism 34 to move downward to clamp the tea bags whose orientation needs to be adjusted. Then, the rotary motor 32 operates, causing the first clamping mechanism 34 and the clamped tea bags to rotate synchronously, adjusting the orientation of the tea bags to the desired orientation, so as to achieve a distribution state where every two adjacent tea bags are opposite each other.

[0068] Reference Figure 32 A pressure sensor is provided at the clamping end of the first clamping mechanism 34. The pressure sensor is electrically connected to the power component of the first clamping mechanism 34 so as to control the clamping force on the first clamping mechanism 34 through the pressure sensor, so that the clamping force is always within a suitable range, thereby avoiding the situation where the tea leaves are crushed due to excessive clamping force or the tea bag cannot be effectively clamped due to insufficient clamping force.

[0069] Reference Figure 32The pushing mechanism 4 includes a first electric push rod 41 mounted on the first conveyor belt 1. A baffle 42 is mounted on the side of the first conveyor belt 1 opposite to the first electric push rod 41, and the distance between the baffle 42 and the first conveyor belt 1 is less than the width of the tea bag when it is laid flat. When the pushing mechanism 4 is running, the first electric push rod 41 pushes the tea bag to the gap between the first conveyor belt 1 and the baffle 42. Since the space in this gap is too small to accommodate the tea bag when it is laid flat, the tea bag changes from a flat position to a side-standing position and falls onto the device plate 6, thereby adjusting the standing position of the tea bag.

[0070] Reference Figure 32 The bottom of the baffle 42 is provided with a notch. The distance from the top of the notch to the device plate 6 is greater than the height distance when the tea bag is standing on its side, so that the merging mechanism 5 can contact the tea bag through the notch and ensure the normal movement of the tea bag.

[0071] Reference Figure 32 The merging mechanism 5 includes a second electric push rod 51 mounted on the device plate 6. When the merging mechanism 5 is in operation, the second electric push rod 51 pushes the first tea bag that has fallen on the device plate 6 to the end of the device plate 6, and then pushes the second tea bag that has fallen on the device plate 6 to a position where it is in contact with the first tea bag, thereby adjusting the two tea bags to a close fit with each other end to end.

[0072] Reference Figure 32 A baffle 52 is provided at the end of the device plate 6. The height of the baffle 52 is 1 / 3 of the height of the tea bag when it is standing on its side. A pressure sensor is provided at the end of the second electric push rod 51, and the pressure sensor is electrically connected to the second electric push rod 51. The baffle 52 is designed to prevent the tea bag from falling off the device plate 6, and the pressure sensor is designed to adjust the pushing force of the second electric push rod 51, so that the pushing force of the second electric push rod 51 is always within a reasonable range.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
