Abstract
Description
Technical Field
[0001] This utility model relates to the field of tea packaging equipment technology, and more specifically, it relates to a tea bag packaging device. Background Technology
[0002] To facilitate brewing and storage, and for aesthetic purposes, tea packaging in the tea industry mostly uses small bags weighing 5-10 grams. These bags are then placed into boxes to complete the packaging. Since tea bags are usually not filled completely, they need to be folded and arranged before being placed into boxes to reduce the size of the packaging.
[0003] Existing tea packaging machines can only pack tea leaves into bags. After bagging, the tea leaves generally need to be placed into boxes, and then the boxes into cartons. For example, Chinese utility model patent application number CN201520508560.8 discloses a tea gift box packaging production line, including a manual boxing platform, a gift box inkjet printer, a conveyor for the inkjet printer, an automatic laminating and heat shrink machine, a transition conveyor, a manual boxing platform, an automatic box sealing machine, an inkjet printer, an inkjet printer conveyor, a strapping machine, and a non-powered roller. In operation, this tea gift box packaging production line relies on manual labor to arrange the tea bags on the manual boxing platform to facilitate placement into smaller boxes. This method is inefficient and makes it difficult to guarantee product packaging quality, thus requiring further improvement. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a tea bag packaging device to solve the above-mentioned technical problems.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a tea bag packaging device, comprising: a conveying mechanism; a limiting mechanism for restricting the position of the tea bag is provided on the conveying mechanism; and a moving and flipping mechanism for moving and flipping the tea bag, a pushing mechanism for pushing the tea bag into the moving and flipping mechanism, and a folding mechanism for folding the tea bag flipped by the moving and flipping mechanism are sequentially provided on the conveying mechanism.
[0006] Specifically, a conveyor mechanism transports tea bags containing tea leaves, a limiting mechanism restricts the position of the tea bags to ensure they remain within the conveyor, a pushing mechanism pushes the tea bags so that the empty portion of the tea bags enters a moving flipping mechanism. As the tea bags move with the conveyor, the moving flipping mechanism flips the empty portion of the tea bags to a certain angle with the conveyor. A folding mechanism folds the empty portion of the tea bags so that it rests on the tea-filling part of the tea bag. The limiting mechanism further restricts both the tea-filling part and the empty portion of the tea bags, ensuring that the empty portion is tightly attached to the tea-filling part. This completes the automatic sorting of the tea bags. By sorting the tea bags using this tea bag sorting device and folding the empty portion onto the tea-filling part, sorting efficiency is improved, and the packaging quality of the tea bags in subsequent packaging processes is ensured.
[0007] Optionally, the conveying mechanism includes: a chain conveyor belt; a plurality of isolation baffles are provided on the chain conveyor belt, and a storage groove adapted to the size of the tea bag is formed between two adjacent isolation baffles; and a clearance groove adapted to the limiting mechanism is provided on the isolation baffle.
[0008] Specifically, several isolation baffles are set up on the chain conveyor belt to form several storage slots. Each time the chain conveyor belt moves, it only moves the distance between two adjacent isolation baffles, so as to facilitate the sorting of tea bags placed in each storage slot.
[0009] Optionally, the moving and flipping mechanism includes: a first guide crank and a second guide crank; the first guide crank and the second guide crank are spaced apart on the conveying mechanism; the first guide crank is used to guide the empty part of the tea bag to contact the second guide crank, and the second guide crank is used to push the empty part of the tea bag to form an angle with the conveying mechanism.
[0010] Specifically, when the conveying mechanism moves, the empty part of the tea bag is initially below the first guide crank. As the conveying mechanism moves, the empty part of the tea bag comes into contact with the second guide crank, which is slightly higher than the first guide crank. Under the limiting action of the first and second guide cranks, the empty part of the tea bag gradually rises and forms an angle with the tea-filling part of the tea bag.
[0011] Optionally, the first guide rod includes: a first bent rod and a first straight rod; the first bent rod is disposed at one end of the first straight rod; the first bent rod is in the shape of an arc with an opening facing upward.
[0012] Specifically, by setting the first bending rod to an arc shape with the opening facing downwards, the empty part of the tea bag can be guided when it comes into contact with the first bending rod, so that the empty part of the tea bag can smoothly enter the bottom of the first straight rod.
[0013] Optionally, the second guide rod includes: a second bent rod and a second straight rod; the second bent rod is disposed at one end of the second straight rod; the second bent rod is in the shape of a downward-opening arc.
[0014] Specifically, as the empty part of the tea bag moves below the first straight rod, the second bent rod with its opening facing downwards guides the empty part of the tea bag. The lower end of the empty part of the tea bag contacts the upper end of the second bent rod, guiding the empty part of the tea bag to the top of the second straight rod. Since the height of the second straight rod is higher than that of the first straight rod, the empty part of the tea bag tilts upwards around the first straight rod, thus achieving the flipping of the empty part of the tea bag.
[0015] Optionally, the folding mechanism includes: a first push plate assembly, a second push plate assembly, and a pressing assembly; the first push plate assembly is disposed on one side of the chain conveyor belt, and the second push plate assembly is disposed on the other side of the chain conveyor belt; the pressing assembly is disposed at the lower end of the second push plate assembly; the pressing assembly is used to press the tea bag onto the moving flipping mechanism.
[0016] Specifically, when the tea bag moves to the folding mechanism, the pressing component first pushes the tea bag, pressing it firmly onto the moving and flipping mechanism. The first pusher component folds the empty part of the tea bag, pushing it to press the empty part against the tea-filling part. Then, the second pusher component squeezes the first pusher component, ensuring that the empty part of the tea bag is always pressed against the tea-filling part when the tea bag is moving. When the tea bag moves into the subsequent limiting mechanism, both the empty part and the tea-filling part of the tea bag are simultaneously limited.
[0017] Optionally, the first pusher assembly includes: a first pusher cylinder and a first folding pusher; the first pusher cylinder is disposed on one side of the chain conveyor belt, and the first folding pusher is disposed at the output end of the first pusher cylinder.
[0018] Specifically, when folding the empty part of the tea bag, the first folding pusher is pushed by the first pusher cylinder to move towards the tea bag. The first folding pusher contacts the empty part of the tea bag and pushes the empty part of the tea bag to tilt towards the tea-filling part of the tea bag, so that the empty part of the tea bag is gradually folded and placed below the first folding pusher, so that the empty part of the tea bag overlaps with the tea-filling part of the tea bag.
[0019] Optionally, the second pusher assembly includes: a second pusher cylinder and a second folding pusher; the second pusher cylinder is disposed on the other side of the chain conveyor belt, and the second folding pusher is disposed at the output end of the second pusher cylinder and located above the first folding pusher.
[0020] Specifically, after the first folding pusher overlaps the empty part of the tea bag with the tea-filling part of the tea bag, the second pusher cylinder pushes the second folding pusher towards the first pusher cylinder. The lower end of the second folding pusher contacts and squeezes the first folding pusher, further pressing the empty part of the tea bag onto the tea-filling part of the tea bag, so that the tea bag can enter the subsequent limiting mechanism in a folded posture.
[0021] In summary, this utility model has the following beneficial effects: A conveying mechanism transports tea bags containing tea leaves; a limiting mechanism restricts the position of the tea bags, ensuring they remain within the conveying mechanism; a pushing mechanism pushes the tea bags, causing the empty portion of the tea bags to enter a moving flipping mechanism; as the tea bags move with the conveying mechanism, the moving flipping mechanism flips the empty portion of the tea bags to a certain angle with the conveying mechanism; a folding mechanism folds the empty portion of the tea bags, placing it on the tea-filling part of the tea bag; and a limiting mechanism restricts both the tea-filling part and the empty portion of the tea bags, ensuring the empty portion is tightly attached to the tea-filling part. This completes the automatic sorting of the tea bags. By using a tea bag sorting device to fold the empty portion of the tea bags onto the tea-filling part, sorting efficiency is improved, and the packaging quality of the tea bags in subsequent packaging processes is ensured.

The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature.
[0029] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0030] Example 1
[0031] This embodiment provides a tea bag packaging device, such as... Figure 1-4 As shown, it includes: a conveying mechanism 1; a limiting mechanism 2 provided on the conveying mechanism 1 for restricting the position of the tea bag 8; a moving and flipping mechanism 3 for moving and flipping the tea bag 8, a pushing mechanism 4 for pushing the tea bag 8 into the moving and flipping mechanism 3, and a folding mechanism 5 for folding the tea bag 8 flipped by the moving and flipping mechanism 3.
[0032] Specifically, a tea bag 8 containing tea leaves is conveyed by a conveying mechanism 1. A limiting mechanism 2 restricts the position of the tea bag 8 to ensure it remains within the conveying mechanism 1. A pushing mechanism 4 pushes the tea bag 8, causing the empty portion 81 to enter a moving flipping mechanism 3. As the tea bag 8 moves with the conveying mechanism 1, the moving flipping mechanism 3 flips the empty portion 81 to a certain angle with the conveying mechanism 1. A folding mechanism 5 folds the empty portion 81 onto the tea-filling portion 82 of the tea bag. The limiting mechanism 2 further restricts the tea-filling portion 82 and the empty portion 81, ensuring the empty portion 81 is tightly attached to the tea-filling portion 82. This completes the automatic sorting of the tea bag 8. By sorting the tea bags using this tea bag sorting device and folding the empty portion onto the tea-filling portion, sorting efficiency is improved, ensuring the packaging quality of the tea bags in subsequent packaging processes.
[0033] In this embodiment, the pushing mechanism 4 includes a cylinder, and a pushing plate is provided at the output end of the cylinder. When the empty part 81 of the tea bag moves to the moving flipping mechanism 3, the cylinder pushes the pushing plate so that the empty part 81 of the tea bag is completely inside the moving flipping mechanism 3. The empty part 81 of the tea bag flips under the action of the moving flipping mechanism 3 so that the folding mechanism 5 can fold the empty part 81 of the tea bag.
[0034] Optionally, the conveying mechanism 1 includes: a chain conveyor belt 101; a plurality of isolation baffles 102 are provided on the chain conveyor belt 101, and a storage groove 6 adapted to the size of the tea bag 8 is formed between two adjacent isolation baffles 102; and a clearance groove 7 adapted to the limiting mechanism 2 is provided on the isolation baffles 102.
[0035] Specifically, several storage slots 6 are formed on the chain conveyor belt 101 by setting several isolation baffles 102. Each time the chain conveyor belt 101 moves, it only moves the distance between two adjacent isolation baffles 102, so as to facilitate the sorting of tea bags 8 placed in each storage slot 6.
[0036] The chain conveyor belt 101 is driven by a stepper motor, which causes the chain conveyor belt 101 to start intermittently, and each movement causes the isolation baffle 102 to move the same distance.
[0037] Optionally, the moving and flipping mechanism 3 includes: a first guide crank 31 and a second guide crank 32; the first guide crank 31 and the second guide crank 32 are spaced apart on the conveying mechanism 1; the first guide crank 31 is used to guide the empty part 81 of the tea bag to contact the second guide crank 32, and the second guide crank 32 is used to push the empty part 81 of the tea bag to form an angle with the conveying mechanism 1.
[0038] Specifically, when the conveying mechanism 1 moves, the empty part 81 of the tea bag is initially below the first guide crank 31. As the conveying mechanism 1 conveys, the empty part 81 of the tea bag comes into contact with the second guide crank 32, and the second guide crank 32 is slightly higher than the first guide crank 31. Under the limiting action of the first guide crank 31 and the second guide crank 32, the empty part 81 of the tea bag gradually rises and forms an angle with the tea-filling part 82 of the tea bag.
[0039] The first guide crank 31 is positioned between the second guide crank 32 and the chain conveyor belt 101, and the empty portion 81 of the tea bag contacts the first guide crank 31 first, and then contacts the second guide crank 32. The first guide crank 31 is mounted on the platform of the chain conveyor belt 101 by a bracket, and the bracket is fixed to the upper end of the first guide crank 31 to ensure that the empty portion 81 of the tea bag can pass normally through the lower end of the bracket.
[0040] Optionally, the first guide rod 31 includes: a first bent rod 311 and a first straight rod 312; the first bent rod 311 is disposed at one end of the first straight rod 312; the first bent rod 311 is an arc shape with the opening facing upward.
[0041] Specifically, by setting the first bending rod 311 to an arc shape with the opening facing downwards, the empty part 81 of the tea bag can be guided when it comes into contact with the first bending rod 311, so that the empty part 81 of the tea bag can smoothly enter below the first straight rod 312.
[0042] Optionally, the second guide rod 32 includes: a second bent rod 321 and a second straight rod 322; the second bent rod 321 is disposed at one end of the second straight rod 322; the second bent rod 321 is in the shape of an arc with an opening facing downward.
[0043] Specifically, when the empty portion 81 of the tea bag moves below the first straight rod 312, the downward-opening second bent rod 321 guides the empty portion 81 of the tea bag. The lower end of the empty portion 81 of the tea bag contacts the upper end of the second bent rod 321, guiding the empty portion 81 of the tea bag to the upper part of the second straight rod 322. Since the height of the second straight rod 322 is higher than that of the first straight rod 312, the empty portion 81 of the tea bag tilts upward around the first straight rod 312, thus achieving the flipping of the empty portion 81 of the tea bag.
[0044] The second bending rod 321 is fixed to the platform of the chain conveyor belt 101. Since the empty part 81 of the tea bag only passes through the upper end of the second bending rod 321 and the second straight rod 322, the support at the lower end of the second bending rod 321 and the second straight rod 322 will not affect the folding of the empty part 81 of the tea bag.
[0045] Optionally, the folding mechanism 5 includes: a first push plate assembly 51, a second push plate assembly 52, and a pressing assembly 53; the first push plate assembly 51 is disposed on one side of the chain conveyor belt 101, and the second push plate assembly 52 is disposed on the other side of the chain conveyor belt 101; the pressing assembly 53 is disposed at the lower end of the second push plate assembly 52; the pressing assembly 53 is used to press the tea bag 8 onto the moving flipping mechanism 3.
[0046] Specifically, when the tea bag 8 moves to the folding mechanism 5, the pressing component 53 first pushes the tea bag 8, pressing it against the moving and flipping mechanism 3. The empty part 81 of the tea bag is folded by the first push plate component 51, pushing the empty part 81 of the tea bag to press it against the tea-filling part 82 of the tea bag. Then, the second push plate component 52 squeezes the first push plate component 51 to ensure that the empty part 81 of the tea bag is always pressed against the tea-filling part 82 of the tea bag when the tea bag 8 is moved. When the tea bag 8 moves into the subsequent limiting mechanism 2, the empty part 81 of the tea bag and the tea-filling part 82 of the tea bag are simultaneously limited.
[0047] Specifically, the limiting mechanism 2 includes a first limiting plate 21 and a second limiting plate 22. The first limiting plate 21 covers the moving and flipping mechanism 3 and the folding mechanism 5, and the second limiting plate 22 covers the folding mechanism 5 and the rear station. The overlapping part of the first limiting plate 21 and the second limiting plate 22 is inclined downward. The second limiting plate 22 overlaps the first limiting plate 21. The first push plate assembly 51 and the second push plate assembly 52 are located at the overlap of the first limiting plate 21 and the second limiting plate 22. The first push plate assembly 51 pushes the empty part 81 of the tea bag between the first limiting plate 21 and the second limiting plate 22. The second push plate assembly 52 presses against the first push plate assembly 51 and is located below the second limiting plate 22, further limiting the empty part 81 of the tea bag so that the empty part 81 of the tea bag can smoothly transition from above the first limiting plate 21 to below the second limiting plate 22.
[0048] Example 2
[0049] This embodiment provides a tea bag packaging device, such as... Figure 1-4 As shown, it includes: a conveying mechanism 1; a limiting mechanism 2 provided on the conveying mechanism 1 for restricting the position of the tea bag 8; a moving and flipping mechanism 3 for moving and flipping the tea bag 8, a pushing mechanism 4 for pushing the tea bag 8 into the moving and flipping mechanism 3, and a folding mechanism 5 for folding the tea bag 8 flipped by the moving and flipping mechanism 3.
[0050] Specifically, a tea bag 8 containing tea leaves is conveyed by a conveying mechanism 1. A limiting mechanism 2 restricts the position of the tea bag 8 to ensure that the tea bag 8 is within the conveying mechanism 1. A pushing mechanism 4 pushes the tea bag 8 so that the empty part 81 of the tea bag enters the moving flipping mechanism 3. As the tea bag 8 moves with the conveying mechanism 1, the moving flipping mechanism 3 flips the empty part 81 of the tea bag to a certain angle with the conveying mechanism 1. A folding mechanism 5 folds the empty part 81 of the tea bag so that the empty part 81 of the tea bag is folded onto the tea-filling part 82 of the tea bag. The limiting mechanism 2 restricts the tea-filling part 82 and the empty part 81 of the tea bag to ensure that the empty part 81 of the tea bag is tightly attached to the tea-filling part 82 of the tea bag, thus completing the automatic sorting of the tea bag 8.
[0051] In this embodiment, the pushing mechanism 4 includes a cylinder, and a pushing plate is provided at the output end of the cylinder. When the empty part 81 of the tea bag moves to the moving flipping mechanism 3, the cylinder pushes the pushing plate so that the empty part 81 of the tea bag is completely inside the moving flipping mechanism 3. The empty part 81 of the tea bag flips under the action of the moving flipping mechanism 3 so that the folding mechanism 5 can fold the empty part 81 of the tea bag.
[0052] Optionally, the conveying mechanism 1 includes: a chain conveyor belt 101; a plurality of isolation baffles 102 are provided on the chain conveyor belt 101, and a storage groove 6 adapted to the size of the tea bag 8 is formed between two adjacent isolation baffles 102; and a clearance groove 7 adapted to the limiting mechanism 2 is provided on the isolation baffles 102.
[0053] Specifically, several storage slots 6 are formed on the chain conveyor belt 101 by setting several isolation baffles 102. Each time the chain conveyor belt 101 moves, it only moves the distance between two adjacent isolation baffles 102, so as to facilitate the sorting of tea bags 8 placed in each storage slot 6.
[0054] The chain conveyor belt 101 is driven by a stepper motor, which causes the chain conveyor belt 101 to start intermittently, and each movement causes the isolation baffle 102 to move the same distance.
[0055] Optionally, the moving and flipping mechanism 3 includes: a first guide crank 31 and a second guide crank 32; the first guide crank 31 and the second guide crank 32 are spaced apart on the conveying mechanism 1; the first guide crank 31 is used to guide the empty part 81 of the tea bag to contact the second guide crank 32, and the second guide crank 32 is used to push the empty part 81 of the tea bag to form an angle with the conveying mechanism 1.
[0056] Specifically, when the conveying mechanism 1 moves, the empty part 81 of the tea bag is initially below the first guide crank 31. As the conveying mechanism 1 conveys, the empty part 81 of the tea bag comes into contact with the second guide crank 32, and the second guide crank 32 is slightly higher than the first guide crank 31. Under the limiting action of the first guide crank 31 and the second guide crank 32, the empty part 81 of the tea bag gradually rises and forms an angle with the tea-filling part 82 of the tea bag.
[0057] The first guide crank 31 is positioned between the second guide crank 32 and the chain conveyor belt 101, and the empty portion 81 of the tea bag contacts the first guide crank 31 first, and then contacts the second guide crank 32. The first guide crank 31 is mounted on the platform of the chain conveyor belt 101 by a bracket, and the bracket is fixed to the upper end of the first guide crank 31 to ensure that the empty portion 81 of the tea bag can pass normally through the lower end of the bracket.
[0058] Optionally, the first guide rod 31 includes: a first bent rod 311 and a first straight rod 312; the first bent rod 311 is disposed at one end of the first straight rod 312; the first bent rod 311 is an arc shape with the opening facing upward.
[0059] Specifically, by setting the first bending rod 311 to an arc shape with the opening facing downwards, the empty part 81 of the tea bag can be guided when it comes into contact with the first bending rod 311, so that the empty part 81 of the tea bag can smoothly enter below the first straight rod 312.
[0060] Optionally, the second guide rod 32 includes: a second bent rod 321 and a second straight rod 322; the second bent rod 321 is disposed at one end of the second straight rod 322; the second bent rod 321 is in the shape of an arc with an opening facing downward.
[0061] Specifically, when the empty portion 81 of the tea bag moves below the first straight rod 312, the downward-opening second bent rod 321 guides the empty portion 81 of the tea bag. The lower end of the empty portion 81 of the tea bag contacts the upper end of the second bent rod 321, guiding the empty portion 81 of the tea bag to the upper part of the second straight rod 322. Since the height of the second straight rod 322 is higher than that of the first straight rod 312, the empty portion 81 of the tea bag tilts upward around the first straight rod 312, thus achieving the flipping of the empty portion 81 of the tea bag.
[0062] The second bending rod 321 is fixed to the platform of the chain conveyor belt 101. Since the empty part 81 of the tea bag only passes through the upper end of the second bending rod 321 and the second straight rod 322, the support at the lower end of the second bending rod 321 and the second straight rod 322 will not affect the folding of the empty part 81 of the tea bag.
[0063] Optionally, the folding mechanism 5 includes: a first push plate assembly 51, a second push plate assembly 52, and a pressing assembly 53; the first push plate assembly 51 is disposed on one side of the chain conveyor belt 101, and the second push plate assembly 52 is disposed on the other side of the chain conveyor belt 101; the pressing assembly 53 is disposed at the lower end of the second push plate assembly 52; the pressing assembly 53 is used to press the tea bag 8 onto the moving flipping mechanism 3.
[0064] Specifically, when the tea bag 8 moves to the folding mechanism 5, the pressing component 53 first pushes the tea bag 8, pressing it against the moving and flipping mechanism 3. The empty part 81 of the tea bag is folded by the first push plate component 51, pushing the empty part 81 of the tea bag to press it against the tea-filling part 82 of the tea bag. Then, the second push plate component 52 squeezes the first push plate component 51 to ensure that the empty part 81 of the tea bag is always pressed against the tea-filling part 82 of the tea bag when the tea bag 8 is moved. When the tea bag 8 moves into the subsequent limiting mechanism 2, the empty part 81 of the tea bag and the tea-filling part 82 of the tea bag are simultaneously limited.
[0065] Specifically, the limiting mechanism 2 includes a first limiting plate 21 and a second limiting plate 22. The first limiting plate 21 covers the moving and flipping mechanism 3 and the folding mechanism 5, and the second limiting plate 22 covers the folding mechanism 5 and the rear station. The overlapping part of the first limiting plate 21 and the second limiting plate 22 is inclined downward. The second limiting plate 22 overlaps the first limiting plate 21. The first push plate assembly 51 and the second push plate assembly 52 are located at the overlap of the first limiting plate 21 and the second limiting plate 22. The first push plate assembly 51 pushes the empty part 81 of the tea bag between the first limiting plate 21 and the second limiting plate 22. The second push plate assembly 52 presses against the first push plate assembly 51 and is located below the second limiting plate 22, further limiting the empty part 81 of the tea bag so that the empty part 81 of the tea bag can smoothly transition from above the first limiting plate 21 to below the second limiting plate 22.
[0066] Optionally, the first pusher assembly 51 includes: a first pusher cylinder 511 and a first folding pusher 512; the first pusher cylinder 511 is disposed on one side of the chain conveyor belt 101, and the first folding pusher 512 is disposed at the output end of the first pusher cylinder 511.
[0067] Specifically, when folding the empty part 81 of the tea bag, the first folding push plate 512 is pushed towards the tea bag 8 by the first push plate cylinder 511. The first folding push plate 512 contacts the empty part 81 of the tea bag and pushes the empty part 81 of the tea bag to tilt towards the tea-filling part 82 of the tea bag, so that the empty part 81 of the tea bag is gradually folded and placed under the first folding push plate 512, so that the empty part 81 of the tea bag overlaps with the tea-filling part 82 of the tea bag.
[0068] Optionally, the second pusher assembly 52 includes: a second pusher cylinder 521 and a second folding pusher 522; the second pusher cylinder 521 is disposed on the other side of the chain conveyor belt 101, and the second folding pusher 522 is disposed at the output end of the second pusher cylinder 521 and located above the first folding pusher 512.
[0069] Specifically, after the first folding push plate 512 overlaps the empty part 81 of the tea bag with the tea-filling part 82 of the tea bag, the second push plate cylinder 521 pushes the second folding push plate 522 to move towards the first push plate cylinder 511. The lower end of the second folding push plate 522 contacts and squeezes the first folding push plate 512, further pressing the empty part 81 of the tea bag onto the tea-filling part 82 of the tea bag, so that the tea bag 8 can enter the subsequent limiting mechanism 2 in a folded posture.
