Description

Technical Field

[0001] This invention relates to the field of tea packaging technology, and in particular to a fully automatic tea bag blending and packaging equipment and its packaging method. Background Technology

[0002] In the production of teas with different flavors, different teas need to be blended and matched according to specific proportions. After blending, the tea is packed into tea bags for subsequent packaging. In the current tea production process, the various procedures in the blending and packaging processes need to be carried out separately using different devices. The next process can only proceed after the previous process is completed, making it difficult to achieve a complete process from blending to packaging, resulting in low work efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide a fully automatic tea bag blending and packaging equipment and its packaging method, so as to solve the problems mentioned in the background art, such as the difficulty in realizing the whole process of tea blending and packaging and the low work efficiency.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a fully automatic tea bag blending and packaging equipment, comprising a housing, an L-shaped device plate inside the housing, three first assembly hoppers arranged in parallel between the top of the housing and the L-shaped device plate, the first assembly hoppers being connected to the top of the L-shaped device plate via vibration components, three circular vibrating discs arranged side by side on the top of the L-shaped device plate, the discharge ports of the three first assembly hoppers corresponding one-to-one with the inlets of the circular vibrating discs, a weighing module being provided at the discharge port of each of the three circular vibrating discs, and second assembly hoppers being respectively arranged on the side walls of the L-shaped device plate. The device includes a second and a third assembly hopper. The second assembly hopper is used to transport tea leaves from the circular vibrating plate to the third assembly hopper. The L-shaped device plate is equipped with a storage mechanism for storing tea bags and a linkage suction cup bag opening mechanism. Below the linkage suction cup bag opening mechanism are a tea bag bottom folding mechanism and a multi-functional tea bag sealing mechanism. The multi-functional tea bag sealing mechanism is located below the tea bag bottom folding mechanism. The L-shaped device plate is equipped with a feeding mechanism and a laser mechanism. The feeding mechanism, the third assembly hopper, and the multi-functional tea bag sealing mechanism are on the same horizontal line, and the laser mechanism is located outside this horizontal line.

[0005] The beneficial effects of this invention are: This invention integrates a linkage-type suction cup bag opening mechanism, a tea bag bottom folding mechanism, a multi-functional tea bag sealing mechanism, a feeding mechanism, and a laser mechanism within the device, and is equipped with multiple weighing hoppers. This allows the device to automatically convey different proportions of various teas according to their production type. The linkage-type suction cup bag opening mechanism, in coordination with the various hoppers, completes the operations of picking up, opening, and filling empty tea bags. After filling, the laser mechanism, feeding mechanism, and multi-functional tea bag sealing mechanism work together to code the tea bags. The coded tea bags are then pushed to the multi-functional tea bag sealing mechanism for sealing. This achieves a complete process from tea blending to packaging, improving production efficiency. Furthermore, during tea packaging, the tea bags are coded immediately after filling, achieving a "one bag, one code" operation. This effectively ensures the accurate correspondence between the tea type and the traceability code within the tea bag, avoiding situations where the traceability code does not match the tea type.

[0008] 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.

[0009] Reference Figure 1-3A fully automatic tea bag blending and packaging equipment includes a housing 79, with an L-shaped device plate 80 built into 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 vibration components. 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. A weighing module is installed at the discharge port of each of the three circular vibrating discs 88. Second assembly hoppers 82 and third assembly hoppers 83 are respectively arranged on the side walls of the L-shaped device plate 80. The assembly hopper 82 is used to transport tea leaves from the circular vibrating plate 88 to the third assembly 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 assembly 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.

[0010] 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.

[0011] Reference Figure 2 , 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.

[0012] 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.

[0013] Reference Figure 2 , Figure 6-8 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.

[0014] 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.

[0015] Reference Figure 7 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.

[0016] Reference Figure 9 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.

[0017] Reference Figure 6An 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.

[0018] Reference Figure 2 , Figure 10 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.

[0019] 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.

[0020] Reference Figure 10-11 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.

[0021] 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.

[0022] Reference Figure 12-13 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.

[0023] Reference Figure 13 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.

[0024] Reference Figure 12 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.

[0025] 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.

[0026] Reference Figure 10Each 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.

[0027] Reference Figure 2 , Figure 14 , Figure 15 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.

[0028] 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.

[0029] Reference Figure 14 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.

[0030] 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.

[0031] Reference Figure 15 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.

[0032] Reference Figure 2 , Figure 16 , Figure 17 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.

[0033] 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.

[0034] Reference Figure 16 , 19 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.

[0035] Reference Figure 18 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.

[0036] 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.

[0037] Reference Figure 17 , 18A 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.

[0038] 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.

[0039] Reference Figure 18 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.

[0040] Reference Figure 19 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.
