They mainly include fully automatic black tea packaging machines, tea bag packaging machines, and black tea dispensing machines.

[0003] The fully automatic black tea packaging machine uses a PLC control system, supporting automatic bag making, filling, sealing, cutting, and counting. Some models are equipped with a color sorting system to select tea leaves, improving the integrity of the finished product, and use ultrasonic sealing technology to ensure a good seal. The tea bag packaging machine uses a servo control system to simultaneously form the inner bag filter paper and the outer bag composite paper. It supports multiple categories including black tea and herbal tea, and is equipped with a vision inspection module to automatically reject products with defective labels. This black tea dispensing machine is suitable for quantitative dispensing of strip-shaped black tea. It employs spiral feeding technology and supports various packaging sizes, including triangular and square packs. The machine is compact and operates with low noise.

[0004] Existing black tea packaging machines often use mechanical structures to cut the tea leaves during feeding, which inevitably damages the tea leaves, causing them to break and crumble. Summary of the Invention

At the position of the feeding pipe above the bridging nozzles, downwardly oriented serrated patterns are provided.

[0008] Preferably, the rotary material distribution system includes a rotary bucket and a material distribution motor. The material distribution motor is mounted on the frame, the rotary bucket is mounted on the output end of the material distribution motor, and each material distribution device is slidably mounted on the rotary bucket. A photoelectric sensor is provided on the top of each material distribution device.

[0009] Preferably, the tape supply system includes a tape supply roller, a plurality of guide rollers and a folding guide, the folding guide is mounted on the frame, the tape supply roller is rotatably mounted on the frame, each of the guide rollers is rotatably mounted on the frame, and a tape supply motor is drivenly connected to the tape supply roller.

[0010] Preferably, the sealing system includes a sealing roller assembly and a separating device. The sealing roller assembly includes two heat sealing rollers arranged opposite each other. The separating device is mounted on a frame and has two mutually opening and closing separating heat sealing plates.

[0012] Preferably, the material dispensing device includes a dispensing cylinder, an upper dispensing cylinder, a lower dispensing cylinder, a pneumatic telescopic device, and a dispensing opening and closing device. The rotary bucket is rotatably mounted on the frame. The upper dispensing cylinder is mounted below the rotary bucket. The dispensing cylinder is slidably mounted inside the upper dispensing cylinder. The lower dispensing cylinder is slidably mounted below the lower dispensing cylinder. The lower dispensing cylinder slides along the top of the injection device. An upper compression spring is provided between the dispensing cylinder and the rotary bucket. A lower compression spring is provided on the side of the lower dispensing cylinder near the top of the injection device. A sliding sleeve is provided on the lower side of the lower compression spring, and the sliding sleeve covers the dispensing cylinder. The lower cylinder slides along its lower side, and the sliding sleeve slides along the top of the injection device. The material distributing opening and closing device is installed inside the distributing cylinder. The pneumatic telescopic device is installed between the distributing cylinder and the lower distributing cylinder. The pneumatic telescopic device is connected to the material distributing opening and closing device. The pneumatic telescopic device is a telescopic airbag. The material distributing opening and closing device includes a material distributing opening and closing plate and a material distributing opening and closing control rod. The material distributing opening and closing control rod is slidably installed on the distributing cylinder.

[0014] The packaging process for black tea includes the following steps: S1: The feeding system loads the black tea material; S2: The material feeding system is blocked when the bridging nozzle is spraying air; the black tea material falls when the bridging nozzle is not spraying air. S3: The rotary material distribution system drives each material distribution device to rotate. When the material distribution device rotates to the lower side of the feeding system, the material in the feeding system falls to the material distribution device. S4: When the material distribution device rotates back to the upper side of the feeding device, the black tea material falls into the feeding system; S5: The feeding system drives the packaging belt through, and the sealing system seals the packaging belt.

[0015] The beneficial effects of this invention are: A rotary dispensing system is mounted on a frame and includes several dispensing devices. A feeding system is also mounted on the frame, with a pneumatic bridging device at its bottom. This bridging of the tea leaves refers to the artificial creation of blockages during feeding, controlling the descent rhythm of the tea leaves. The pneumatic bridging device has an upward-sloping bridging nozzle at its end, located at the bottom of the feeding system. When this nozzle sprays air, it lifts the tea leaves upwards, bridging them at the nozzle and stopping the feeding system. This prevents the tea leaves from breaking due to misalignment between the feeding system and the dispensing devices during rotation, ensuring the integrity of the tea leaves. The rotary dispensing system has several components corresponding to the feeding system. The corresponding dispensing device receives the black tea leaves falling from the feeding system and carries them to the dispensing device. The feeding system is mounted on the frame. The rotary dispensing system is connected to an injection device on its lower side. The injection device is mounted on the frame. When the corresponding dispensing device moves to the upper side of the injection device, the injection device aligns with the corresponding dispensing device. Each dispensing device moves along the top of the injection device. The top of the dispensing device is retractable. The injection device points towards the feeding system. Because the top of the dispensing device is retractable, it disengages from the feeding system when rotating, preventing the black tea leaves from breaking and ensuring their integrity. The sealing system is mounted on the frame and on the feeding path of the feeding system, thus sealing the tea leaves as the packaging belt passes through. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings: like Figure 1 — Figure 7As shown, this embodiment provides a black tea packaging machine, including a frame 1, a feeding system 2, a rotary dispensing system 3, a conveyor belt system 4, and a sealing system 5. The rotary dispensing system 3 is mounted on the frame 1 and is equipped with several dispensing devices 31. The feeding system 2 is mounted on the frame 1, and a pneumatic bridging device 6 is provided at the bottom of the feeding system 2. The black tea material bridging referred to here refers to the artificial blockage of black tea material during feeding, thereby controlling the falling rhythm of the black tea material. The end of the bridging device 6 is connected to an upwardly angled bridging nozzle 23, which is located at the bottom of the feeding system 2. When the bridging nozzle 23 sprays air, it lifts the black tea material upward, achieving bridging of the black tea material in the feeding system 2 at the bridging nozzle 23. This stops the feeding system 2 from feeding, preventing the black tea material from breaking in the area between the feeding system 2 and the distributing device 31 due to their mutual misalignment when the distributing device 31 rotates, thus ensuring the black tea material is safe. The rotary dispensing system 3 has several dispensing devices 31 corresponding to the corresponding feeding system 2. The tea leaves falling from the feeding system 2 fall to the dispensing device 31 and are carried by it. The feeding system 4 is mounted on the frame 1. A feeding device 7 is connected to the lower side of the rotary dispensing system 3. The feeding device 7 is mounted on the frame 1. When the corresponding dispensing device 31 moves to the upper side of the feeding device 31, the feeding device 7 corresponds to the corresponding dispensing device 31. Each dispensing device... The material distribution device 31 moves along the top of the feeding device 7. The top of the material distribution device 31 is retractable. The feeding device 7 points towards the feeding system 4. Since the top of the material distribution device 31 is retractable, when the material distribution device 31 rotates, the material distribution device 31 is disengaged from the feeding system 2, which avoids the black tea material from breaking when the material distribution device 31 rotates, thus ensuring the integrity of the black tea material. The sealing system 5 is installed on the frame 1 and on the feeding path of the feeding system 4, so as to achieve sealing when the packaging belt passes through.

[0026] Specifically, the feeding system 2 includes a feeding hopper 21 and a feeding pipe 22. The feeding pipe 22 is installed on the lower side of the feeding hopper 21. Several upward-sloping bridging nozzles 23 are provided on the lower bottom of the feeding pipe 22. The pneumatic bridging device 6 sprays air upward through the bridging nozzles 23 to lift the black tea material in the feeding pipe 22, thereby realizing the bridging of the feeding system 2. In order to achieve the bridging of the black tea material more quickly when it is lifted by the airflow, a downward-pointing serrated pattern is provided on the feeding pipe 22 above the bridging nozzles 23. When the bridging nozzles 23 spray air upward, they block the black tea material from continuing to rise, while when the bridging nozzles 23 do not spray air, the black tea material falls smoothly.

[0027] Specifically, the rotary feeding system 3 includes a rotary bucket 32 ​​and a feeding motor. The feeding motor is mounted on the frame 1, and the rotary bucket 32 ​​is mounted on the output end of the feeding motor. Each feeding device 31 is slidably mounted on the rotary bucket 32. The rotation of the rotary bucket 32 ​​drives the rotation of each feeding device 31. A photoelectric sensor is provided on the top of the feeding device 31. The pneumatic bridging device 6 intermittently blows air to bridge the material, dropping the black tea material into the feeding device 31 in batches. When the pneumatic bridging device 6 blows air to bridge the material, the photoelectric sensor senses the black tea material. When the feeding device 31 is full of material, the photoelectric sensor senses the black tea material, and the pneumatic bridging device 6 continues to blow air to bridge the material, thereby stopping the feeding.

[0028] Specifically, the tape supply system 4 includes a tape supply roller 41, several guide rollers 42, and a folding guide 43. The folding guide 43 is mounted on the frame 1. The tape supply roller 41 is rotatably mounted on the frame 1. Each guide roller 42 is rotatably mounted on the frame 1. A tape supply motor is connected to the tape supply roller 41 to supply the packaging tape. After the packaging tape is unwound from the tape supply roller 41, it is guided by the guide rollers 42 until it is folded by the folding guide 43, which facilitates the subsequent sealing system to separate and seal the packaging tape.

[0029] Specifically, the sealing system 5 includes a sealing roller device 51 and a separating device 52. The sealing roller device 51 includes two heat sealing rollers arranged opposite each other to achieve folding and sealing of the packaging tape. The separating device 52 is installed on the frame 1 and has two heat sealing plates that open and close to each other to separate the packaging tape.

[0030] Specifically, the pneumatic bridging device 6 is a pneumatic blower, which is connected to each bridging nozzle 23 through a duct to realize the bridging of the bridging nozzle 23.

[0031] Specifically, the material distribution device 31 includes a material distribution cylinder 311, an upper material distribution cylinder 312, a lower material distribution cylinder 313, a pneumatic telescopic device 314, and a material distribution opening and closing device 315. The rotary bucket 32 ​​is rotatably mounted on the frame 1. The upper material distribution cylinder 312 is mounted below the rotary bucket 32. The material distribution cylinder 311 is slidably mounted inside the upper material distribution cylinder 312. The lower material distribution cylinder 313 is slidably mounted below the material distribution cylinder 311. The lower material distribution cylinder 313 slides along the top of the injection device 7. An upper compression spring 318 is provided between the material distribution cylinder 311 and the rotary bucket 32. A lower compression spring 316 is provided on the side of the lower material distribution cylinder 313 near the top of the injection device 7. A sliding sleeve 317 is provided on the lower side of 16. The sliding sleeve 317 slides around the lower side of the material distribution cylinder 313. On the other hand, the sliding sleeve 317 slides along the top of the feeding device 7. The sliding sleeve 317 can be replaced after wear, which increases the service life of the material distribution cylinder 313. The material distribution opening and closing device 315 is installed in the material distribution cylinder 311. The pneumatic telescopic device 314 is installed between the material distribution cylinder 311 and the material distribution cylinder 313. The pneumatic telescopic device 314 is connected to the material distribution opening and closing device 315. The pneumatic telescopic device 314 is a telescopic airbag. The telescopic movement of the pneumatic telescopic device 314 drives the material distribution upper cylinder 312 away from the feeding system 2 to avoid the breakage of the black tea material.

[0032] The dispensing opening and closing device 315 includes a dispensing opening and closing plate 3151 and a dispensing opening and closing control rod 3152. The dispensing opening and closing control rod 3152 is slidably mounted on the dispensing cylinder 311. The dispensing opening and closing control rod 3152 presses against the pneumatic telescopic device 314, thereby achieving sliding during the extension and retraction of the pneumatic telescopic device 314. The dispensing opening and closing plate 3151 is an elastic plastic plate, which is installed inside the lower dispensing cylinder 313. When the pneumatic telescopic device 314 inflates, the dispensing cylinder 311 rises until the dispensing cylinder... The material cylinder 311 is adapted to the feeding pipe 22. At the same time, the material distribution opening and closing plate 3151 extends, so that the two material distribution opening and closing plates 3151 approach each other and close the bottom of the material distribution cylinder 311, which facilitates the weighing of the black tea material in the material distribution cylinder 311. When the pneumatic telescopic device 314 shrinks, the material distribution cylinder 311 descends until the material distribution cylinder 311 is separated from the feeding pipe 22. At the same time, the material distribution opening and closing plate 3151 retracts, so that the two material distribution opening and closing plates 3151 move away from each other and open the bottom of the material distribution cylinder 311, allowing the black tea material to fall.

[0033] Specifically, the feeding device 7 includes a feeding plate 72 and a feeding pipe 71. The feeding device 31 slides along the top of the feeding plate 72, and the feeding pipe 71 is installed on the feeding plate 72. The feeding pipe 71 points to the feeding system 4 to realize the batch feeding of black tea material.

[0034] The packaging process for black tea includes the following steps: S1: Feeding system 2 loads black tea leaves; S2: When the bridging nozzle 23 is spraying air, the material feeding system 2 is blocked; when the bridging nozzle 23 is not spraying air, the black tea material falls. S3: The rotary material distribution system 3 drives each material distribution device 31 to rotate. When the material distribution device 31 rotates to the lower side of the feeding system 2, the material in the feeding system 2 falls to the material distribution device 31. S4: When the material distribution device 31 rotates to the upper side of the material feeding device 7, the black tea material falls into the feeding system 4; S5: The feeding system 4 drives the packaging belt through, and the sealing system 5 seals the packaging belt.
