Description

Technical Field

[0001] This invention relates to the field of tea processing technology, and in particular to a rapid tea packaging sorting device. Background Technology

[0002] The tea packaging process generally includes: soft packaging filling - further packaging (into tea boxes or tin cans, etc.) - sealing - adding labels - packaging and boxing. The soft packaging filling step includes: 1. tea bagging; 2. tea bag sorting and conveying. For soft packaging filling, in order to avoid affecting the smooth operation of subsequent processes, most existing tea packaging production lines rely on manual handling to sort tea bags onto the conveyor belt or sorting them on the conveyor belt. There is a lack of coordination between various devices, resulting in a low level of automation. Because production is carried out by combining manual and machine operations, the speed of manual operation becomes a bottleneck, making it difficult to maximize the production efficiency of the machines and further increasing the production speed. Secondly, in existing tea packaging production lines, the use of conveyor belts to transport tea bags can lead to problems such as improper sorting of tea bags at the front end or mismatched speeds of multiple conveyor belt sections, resulting in material accumulation and jamming. In such cases, manual intervention is required for correction, which is detrimental to packaging production.

[0003] For example, Chinese utility model patent CN216685174U discloses a tea packaging production line, including a small tea bag packaging machine, a converging conveyor, a manual boxing conveyor, an automatic laminating machine, a heat shrink machine, and a manual boxing platform. The converging conveyor receives and transports the finished small tea bags forward, while the manual boxing conveyor connects to the converging conveyor to receive the arriving finished small tea bags and serves as a platform for manual boxing. In this utility model, the small tea bag packaging machine and the converging conveyor are only simply connected via the finished small tea bag conveyor; manual sorting is required after the tea bags are output.

[0004] For example, Chinese utility model patent CN204776114U discloses an automatic tea packaging production line, including a Z-type elevator, an electronic weighing scale, an eight-station bagging machine, a transition conveyor, an accelerating conveyor, a lining conveyor, and an automatic case packer. The electronic weighing scale and the eight-station bagging machine automatically weigh and package the tea, which is then conveyed to the automatic case packer for automatic case packing, followed by automatic sealing, bundling, and coding. This high level of automation reduces the intensity of manual operation and saves labor costs. However, the transition conveyor and accelerating conveyor lack the ability to coordinate material transport, making it difficult to avoid material accumulation. Summary of the Invention

[0005] The present invention addresses the shortcomings of the prior art by providing a rapid tea packaging sorting device. This device uses a clamping component of a packaging and conveying mechanism to sort and transfer tea bags, and uses a detection component to control the feeding and conveying components to achieve quantitative feeding, thereby improving production efficiency.

[0006] This invention provides a rapid tea packaging sorting device, including an automatic packaging machine, a packaging conveying mechanism, and a packaging transfer mechanism. The automatic packaging machine is connected to the packaging conveying mechanism, which is mounted on the packaging transfer mechanism. The packaging conveying mechanism includes a gripping component for removing materials output from the automatic packaging machine. The packaging transfer mechanism includes a conveying component, a feeding component, and a detection component. The feeding component is located at the output end of the conveying component. The detection component is mounted above the conveying component and electrically connected to both the conveying component and the feeding component. It is used to detect whether tea bags are present in a corresponding area, thereby activating or stopping the conveying component and the feeding component.

[0007] Automatic packaging machines, a current technology, are used to package tea leaves into tea bags. A packaging conveying mechanism connects to the automatic packaging machine and the packaging transport mechanism, using gripping components to remove tea bags produced by the automatic packaging machine for transfer and sorting. The packaging transport mechanism transports the tea bags to the next process. A detection component checks the presence of tea bags in corresponding areas, controlling the opening and closing of the conveying and unloading components to coordinate the transport of tea bags, preventing accumulation and achieving quantitative unloading. Specifically, the detection component detects specific areas on the conveying component and the interior and lower areas of the unloading component, transmitting detection signals when material is detected. When material passes over the conveying component and is detected by the detection component, the conveying component transports tea bags according to the detection signal. When the detection component detects material in the unloading component, the conveying component pauses transport according to the detection signal. When the detection component detects material below the unloading component, the unloading component pauses unloading according to the detection signal, and then resumes unloading after a preset time. This rapid tea packaging sorting device combines an automatic packaging machine, a packaging conveying mechanism, and a packaging transfer mechanism. It can solve the problem of manual labor and achieve quantitative transfer of tea bags, preventing material blockage and jamming, which is beneficial to packaging production.

[0008] In a preferred embodiment of the present invention, the gripping assembly includes a gripper assembly, a telescopic cylinder, an electric slider, and a guide assembly. The shaft end of the telescopic cylinder is connected to the gripper assembly, and one side of the telescopic cylinder is also connected to the electric slider. The electric slider reciprocates on the guide assembly.

[0009] The electric slider can slide back and forth on the guide assembly, thereby driving the telescopic cylinder to move towards the automatic packaging machine. The piston rod of the telescopic cylinder extends into the automatic packaging machine, allowing the gripper assembly to enter the output port and grasp the sealed end of the tea bag. When the tea bag needs to be removed, the electric slider drives the telescopic cylinder to slide in the opposite direction, while the piston rod of the telescopic cylinder retracts, causing the gripper assembly to move out of the output port. The gripper assembly then releases the tea bag, placing it on the conveyor assembly. This process simultaneously removes and organizes the tea bags, standardizing their removal from the automatic packaging machine, which is beneficial for the next process and thus improves overall production efficiency.

[0010] In a preferred embodiment of the present invention, the conveying assembly includes a first conveyor belt, a second conveyor belt, and a third conveyor belt connected in sequence, and is provided with a first driving member, a second driving member, and a third driving member accordingly. The packaging and conveying mechanism is disposed above the first conveyor belt, and the detection assembly is disposed above the second conveyor belt and the third conveyor belt.

[0011] The output end of the first conveyor belt connects to the input end of the second conveyor belt, and the output end of the second conveyor belt connects to the input end of the third conveyor belt, thus connecting the conveying components end-to-end. At this time, the packaging and conveying mechanism transports tea bags from the first conveyor belt. The detection component above the second conveyor belt can detect whether there is material at the end of the second conveyor belt, i.e., the output end. Above the third conveyor belt, two detection signals are issued based on the detection results inside and below the feeding component. The third drive unit can receive relevant signals to start and stop, thereby controlling the operation of the third conveyor belt. Specifically, it starts based on the detection signal from the detection component at the end of the second conveyor belt and stops based on the first signal detected inside the feeding component, making material transport controllable and preventing material accumulation in the feeding component. The feeding component continuously feeds material, stopping when the detection component detects the second signal below the feeding component. Feeding resumes after a preset time, thus preventing material blockage below the feeding component. This design achieves coordinated material transport by controlling the third conveyor belt and the feeding component, enabling precise control of material transport, quantitative feeding, and prevention of blockage.

[0012] In a preferred embodiment of the present invention, the detection component includes a first detection element and a second detection element. The first detection element is located at the output end of the second conveyor belt, and the second detection element is located at the output end of the third conveyor belt. Both the first and second detection elements are electrically connected to the third conveyor belt, and the second detection element is also electrically connected to the unloading component.

[0013] The first detection component is responsible for detecting the material presence at the end of the second conveyor belt. The second detection component is responsible for detecting the material presence inside and below the feeding assembly and sending two different signals respectively. The third drive component responds according to the detection signals of the first and second detection components, and the feeding assembly responds according to the detection signal of the second detection component.

[0014] In a preferred embodiment of the present invention, the feeding assembly includes a material box, with two symmetrical through-holes on opposite sides of the bottom of the material box. Two feeding plates are respectively installed through the two through-holes, and a cylinder is connected to the end of each feeding plate away from the material box. A controller is provided on the cylinder, and the controller is electrically connected to the detection assembly. The material box and the cylinder are both fixed on the conveying assembly. One end of the material box is connected to the output end of the conveying assembly, and the top and bottom of the material box are open.

[0015] The sides of the two feeding plates can pass through the through-hole and abut against each other. The extension and retraction of the cylinder allows for an opening and closing effect within the material box. Since the bottom of the material box is open, material can be fed through the feeding plates. The cylinder operates continuously, and the controller can receive relevant signals to pause the cylinder, leaving the tea bags in the material box. At this time, because there are tea bags in the material box, the conveying component will synchronously pause transmission. After a preset time, the cylinder will resume operation to feed tea bags until the material box is empty. The conveying component will then resume outputting tea bags, replenishing the material box. This ensures that only one tea bag is fed each time, achieving precise quantitative feeding of tea bags.

[0016] In a preferred embodiment of the present invention, the guide rail assembly includes a parallel guide rail and a slide rail. The guide rail passes through the electric slider, and a first connecting block and a second connecting block are fixed at both ends of the guide rail, respectively. A connecting plate is fixed between the first connecting block and the second connecting block. The slide rail is disposed on the side of the connecting plate near the guide rail, and the slide rail is slidably connected to the electric slider. The connecting plate is fixedly connected to the automatic packaging machine and the packaging conveying mechanism.

[0017] The guide rail guides and supports the electric slider, and provides friction for the electric slider to slide, thereby driving the gripper assembly to move and realize the picking and moving function of the gripper assembly. The connecting plate can fix the whole structure on the automatic packaging machine and packaging transmission mechanism, making the structure stable.

[0018] In a preferred embodiment of the present invention, the gripper assembly includes a gripper cylinder and a gripper hand, the gripper hand being disposed on the gripper cylinder, and the shaft end of the telescopic cylinder being fixedly connected to the side of the gripper cylinder opposite to the gripper hand.

[0019] The gripper cylinder is fixed to the gripper hand on one side relative to the telescopic cylinder, so the gripper hand can be used to pick up tea bags when driven by the telescopic cylinder.

[0020] In a preferred embodiment of the present invention, the third driving component includes a forward and reverse reversing motor, which drives the first conveyor belt to reverse when it receives a fault signal.

[0021] If the tea packaging quick sorting device is installed in the production line, the forward and reverse motor rotates forward during normal operation. At this time, the first conveyor belt will transport tea bags to the second conveyor belt. When the equipment at the back end of the production line malfunctions and sends a fault signal, the forward and reverse motor will reverse according to the signal, causing the first conveyor belt to transport materials in the opposite direction, stopping the continuous input of tea bags to the back end from the source, thus preventing material blockage.

[0022] In a preferred embodiment of the present invention, the detection component further includes a third detection element and a fourth detection element, both of which are located above the third conveyor belt. The packaging conveying mechanism is also provided with a speed regulator, which is electrically connected to the detection component, the first driving element, the second driving element, and the third driving element.

[0023] The speed controller is used to adjust the rotational speed of the first drive component, the second drive component, and the third drive component according to the detection results of the detection component, thereby controlling the conveying speed of the first conveyor belt, the second conveyor belt, and the third conveyor belt to achieve multi-level speed regulation.

[0024] In a preferred embodiment of the present invention, a plurality of baffles are fixed on the material box, and the bottoms of the plurality of baffles are inclined toward the inside of the material box and connected to the opening edge of the material box.

[0025] Multiple baffles are circumferentially arranged on the opening of the material box. Specifically, the baffles are slightly higher than the upper surface of the conveying component. The conveying component can guide the tea bags into the material box along the baffles on both sides of the material box. At the same time, the bottoms of the multiple baffles move towards the inside of the material box to form an inverted cone shape, which can enlarge the top opening of the material box and facilitate the entry of tea bags.

[0026] The rapid tea packaging sorting device provided by this invention has the following advantages compared with the prior art:

[0027] This invention provides a rapid tea packaging and sorting device. An automatic packaging machine can bag and package loose tea leaves into tea bags. A packaging and conveying mechanism uses a clamping component to connect to the output port of the automatic packaging machine, then removes the tea bags and places them into the packaging and conveying mechanism. The packaging and conveying mechanism transports the tea bags to the next process via a conveying component. During this process, a detection component detects whether a tea bag has passed through, thereby controlling the switching of the conveying and unloading components to control the speed of tea bag transport. This invention replaces manual operation by using a clamping component to remove and transport tea bags, thus enhancing the coordination between the automatic packaging machine and the conveying component, overcoming the limitations of manual labor, further maximizing the equipment's production capacity, and coordinating the unloading and conveying components through the detection component to achieve quantitative delivery of tea bags and avoid material accumulation.

[0042] Example 1

[0043] See Figures 1 to 3 As shown, the present invention provides a rapid tea packaging sorting device, including an automatic packaging machine 1, a packaging conveying mechanism 2, and a packaging transfer mechanism 3. The automatic packaging machine 1 is connected to the packaging conveying mechanism 2, and the packaging conveying mechanism 2 is disposed on the packaging transfer mechanism 3. The packaging conveying mechanism 2 includes a clamping component 21, which is used to remove the material output by the automatic packaging machine 1. The packaging transfer mechanism 3 includes a conveying component 31, a feeding component 32, and a detection component 33. The output end of the conveying component 31 is fixed to the feeding component 32. The detection component 33 is installed above the conveying component 31 and the feeding component 32, and is electrically connected to the conveying component 31 and the feeding component 32. It is used to detect whether there are tea bags in the corresponding area, so as to start or stop the conveying component 31 and the feeding component 32.

[0044] In this embodiment, the automatic packaging machine 1 can use existing equipment to package tea leaves into tea bags. The packaging conveying mechanism 2 is located on the output side of the automatic packaging machine 1 and is used to connect the automatic packaging machine 1 and the packaging conveying mechanism 3. The clamping component 21 removes the tea bags produced by the automatic packaging machine 1, achieving the purpose of transfer and sorting. The packaging conveying mechanism 3 receives the tea bags that have fallen from the packaging conveying mechanism 2 and conveys them to the next process. At the same time, the detection component 33 detects whether there are tea bags in the corresponding area, thereby controlling the opening and closing of the conveying component 31 and the unloading component 32 to coordinate the transmission of tea bags, prevent the tea bags from piling up, and achieve the effect of quantitative unloading. The detection component 33 has multiple detection elements, which are distributed above the conveying component 31. The detection elements can be commonly used sensors on the market. The multiple detection elements are connected to the conveying component 31 and the unloading component 32 through wiring, and a PLC controller is provided in the connection circuit. The PLC controller controls the start and stop of the unloading component 32 and the conveying component 31 by receiving the detection signals from the detection component 33. The detection component 33 can detect a portion of the conveying component 31 and the interior and lower areas of the feeding component 32, respectively. It transmits a detection signal when material is detected. The feeding component 32 can be a top-open device to facilitate internal detection by the detection component 33, and is set to continuously feed material at regular intervals. When material passes over the conveying component 31 and is detected by the detection component 33, the conveying component 31 outputs tea bags based on the detection signal sent by the detection component 33. When the detection component 33 detects material in the feeding component 32, the conveying component 31 pauses output based on the detection signal. When the detection component 33 detects material below the feeding component 32, the feeding component 32 pauses feeding based on the detection signal, and then resumes feeding after a preset time. This preset time is set according to actual conditions and should match the output speed of the conveying component 31 to avoid material accumulation in the feeding component 32. This rapid tea packaging and sorting device combines an automatic packaging machine 1, a packaging conveying mechanism 2, and a packaging transmission mechanism 3. It can solve the shortcomings of manual labor and achieve quantitative tea bag transmission, preventing material blockage and jamming, which is beneficial to packaging production.

[0045] See Figure 2 As shown, the gripping assembly 21 includes a gripper assembly, a telescopic cylinder 213, an electric slider 214, and a guide assembly. The shaft end of the telescopic cylinder 213 is connected to the gripper assembly, and one side of the telescopic cylinder 213 is also connected to the electric slider 214. The electric slider 214 reciprocates on the guide assembly.

[0046] In this embodiment, the electric slider 214 is movably mounted on the guide assembly, allowing it to slide back and forth on the guide assembly. The telescopic cylinder 213 is fixedly connected to the electric slider 214 on one side perpendicular to the piston rod. Thus, the electric slider 214 can drive the telescopic cylinder 213 to move towards the automatic packaging machine 1. In addition, the piston rod of the telescopic cylinder 213 extends towards the automatic packaging machine 1, causing the gripper assembly to extend into the output port of the automatic packaging machine 1, thereby gripping one sealed end of the tea bag. When it is necessary to remove the tea bag, the electric slider 214 moves in the opposite direction using the guide assembly, driving the telescopic cylinder 213 to slide in the opposite direction. At the same time, the piston rod of the telescopic cylinder 213 retracts, causing the gripper assembly to move out of the output port. Subsequently, the gripper assembly releases the tea bag and places it on the conveying assembly 31, preventing the tea bags from piling up. This simultaneously realizes the removal and sorting of tea bags, standardizing the state of the tea bags leaving the automatic packaging machine 1, which is beneficial for the next process and thus improves the overall production efficiency.

[0047] See Figure 3 , 4 As shown, the conveying assembly 31 includes a first conveyor belt 311, a second conveyor belt 312 and a third conveyor belt 313 connected in sequence and with the same conveying direction, and is provided with a first drive member 4, a second drive member 5 and a third drive member 6. The packaging and conveying mechanism 2 is located above the first conveyor belt 311, and the detection assembly 33 is located above the second conveyor belt 312 and the third conveyor belt 313.

[0048] In this embodiment, the conveying assembly 31 adopts a conventional crawler-type conveyor belt. Each of the multiple conveyor belt segments has a limiting housing on both sides. The output end of the first conveyor belt 311 is connected to the input end of the second conveyor belt 312, and the output end of the second conveyor belt 312 is connected to the input end of the third conveyor belt 313. Specifically, the end of the first conveyor belt 311 is located near the starting end of the second conveyor belt 312, and the end of the second conveyor belt 312 is located near the starting end of the third conveyor belt 313, thus connecting the conveying assembly 31 end-to-end and ensuring a smooth connection of the upper surfaces of each conveyor belt segment. The inclination angle of each conveyor belt can be adjusted to adapt to the installation environment. The packaging and conveying mechanism 2 transports tea bags from the first conveyor belt 311. The detection component 33 above the second conveyor belt 312 can detect whether there is material at the end of the second conveyor belt 312, i.e., the output end. Above the third conveyor belt 313, two detection signals can be issued based on the detection results inside and below the feeding component 32. Each of the first drive unit 4, the second drive unit 5, and the third drive unit 6 is equipped with a signal processor. Through wiring connections with other structures, the third drive unit 6 can receive control signals from the PLC controller to start and stop, thereby controlling the operation of the third conveyor belt 313. Specifically, the detection signal from the detection component 33 at the end of the second conveyor belt 312 is converted into a first control signal by the PLC controller. The third drive unit 6 then receives this first control signal and starts. When the detection component 33 detects the first detection signal inside the feeding component 32 and converts it into a second control signal by the PLC controller, the third drive unit 6 receives this second control signal and stops driving, making material transport controllable and preventing material accumulation in the feeding component 32. During continuous feeding, the PLC controller receives the second detection signal from the detection component 33 below the feeding component 32 and controls the feeding component 32 to stop feeding. Feeding resumes after a preset time, thus preventing material blockage below the feeding component 32. This design achieves the effect of coordinating material transport by controlling the third conveyor belt 313 and the feeding component 32, which can accurately control material transport, realize quantitative feeding and prevent blockage.

[0049] See Figure 5 As shown, the detection component 33 includes a first detection element 331 and a second detection element 332. The first detection element 331 is located at the output end of the second conveyor belt 312, and the second detection element 332 is located at the output end of the third conveyor belt 313. Both the first detection element 331 and the second detection element 332 are electrically connected to the third conveyor belt 313. The second detection element 332 is also electrically connected to the unloading component 32.

[0050] In this embodiment, the first detection element 331 is responsible for detecting the material presence at the end of the second conveyor belt 312. The first detection element 331 is equipped with one of the aforementioned sensors, which faces the end of the second conveyor belt 312. The second detection element 332 is responsible for detecting the material presence inside and below the feeding assembly 32 and emitting two signals respectively. Specifically, the second detection element 332 is located above and diagonally opposite the feeding assembly 32, and can be equipped with two of the aforementioned sensors, one facing inside the feeding assembly 32 and the other facing below it. The third drive element 6 responds to the detection signals from the first detection element 331 and the second detection element 332. The feeding assembly 32 responds to the detection signal from the second detection element 332 and starts and stops accordingly.

[0051] See Figure 6 As shown, the feeding assembly 32 includes a material box 321. Two symmetrical through-holes are opened on opposite sides of the bottom of the material box 321. Two feeding plates 322 are respectively installed through the two through-holes. A cylinder 323 is connected to the end of each feeding plate 322 away from the material box 321. A controller is provided on the cylinder 323, and the controller is electrically connected to the detection assembly 33. The material box 321 and the cylinder 323 are both fixed on the conveying assembly 31. One end of the material box 321 is connected to the output end of the conveying assembly 31, and the top and bottom of the material box 321 are open.

[0052] In this embodiment, the feeding plate 322 is an L-shaped plate, with its short side fixedly connected to the top of the piston rod of the cylinder 323, and its long side located in the material box. Both through-holes are elongated elliptical. The cylinders 323 are symmetrically distributed on both sides of the material box 321, and the long sides of the two feeding plates 322 pass through the through-holes and abut against each other. The cylinders 323 drive the piston rod to move the feeding plates 322 closer together or further apart, thus achieving a switching effect in the material box 321. Since the bottom of the material box 321 is open, the feeding plates 322 can be switched to allow material to be fed or temporarily retained. The cylinder 323 operates continuously after being powered on. The PLC controller can receive the second detection signal from the second detection element 332 to adjust the controller, thereby controlling the cylinder 323 to pause, maintaining the abutting state of the feeding plates 322, so that the tea bag remains in the material box 321. At this time, since there are tea bags in the material box 321, the third conveyor belt 313 will pause transmission simultaneously. After a preset time, the cylinder 323 will resume operation to unload the material. After the material box 321 is unloaded, the third conveyor belt 313 will also resume outputting tea bags, thereby replenishing the material box 321 with material. This ensures that only one tea bag is unloaded each time, achieving precise quantitative conveying of tea bags.

[0053] The specific implementation process is as follows: First, the automatic packaging machine 1 outputs tea bags. The gripper assembly, driven by the electric slider 214, extends and retracts to grip the tea bags. Then, the first conveyor belt 311 receives and begins to transport the tea bags. After passing through the second conveyor belt 312, the tea bags reach the end of the second conveyor belt 312. At this time, the first detection element 331 detects the presence of material and sends a signal to the third drive element 6. The third drive element 6 starts, causing the third conveyor belt 313 to start transporting. Then, the material reaches the unloading assembly 32. At this time, the second detection element 332 detects the presence of material in the unloading assembly 32 and sends a first signal to the third drive element 6. The third drive element 6 pauses, causing the third conveyor belt 313 to stop transporting. Finally, after the second detection element 332 detects the presence of material below the unloading assembly 32, it sends a second signal to the unloading assembly 32, causing the unloading assembly 32 to temporarily stop unloading and retain the material. After a preset time, the unloading assembly 32 resumes unloading. At this time, there is empty space below the unloading assembly 32, which can avoid material blockage.

[0054] Example 2

[0055] This embodiment is an improvement on embodiment 1. Furthermore, the automatic packaging machine 1 includes a feeding mechanism, a bag picking mechanism, a heat sealing mechanism, and a machine base arranged in descending order. The feeding mechanism, the bag picking mechanism, and the heat sealing mechanism are all arranged on the machine base. A clamping component 21 is arranged on the outside of the heat sealing mechanism. One end of the connecting plate 219 is connected to the machine base and is arranged close to the heat sealing mechanism.

[0056] In this embodiment, a feeding mechanism is positioned above the bag-picking mechanism, and a heat-sealing mechanism is located below the bag-picking mechanism. The bag-picking mechanism is used to remove the packaging bag, and the feeding mechanism is used to fill the tea leaves into the packaging bag removed by the bag-picking mechanism. Subsequently, the heat-sealing mechanism can vent and seal the filled packaging bag, completing the tea packaging and forming a tea bag. One end of the connecting plate 219 is connected to the machine base, which can fix the insertion position of the gripper assembly in the heat-sealing mechanism, preventing the gripping assembly 21 from moving during use, thereby maintaining stability and improving gripping accuracy.

[0057] Furthermore, the feeding mechanism includes a feeder, a first guide hopper and a second guide hopper located below the feeder, and a feeding hopper movably connected to the second guide hopper. The bottom of the feeder is connected to the first guide hopper, and the bottom of the first guide hopper is connected to the second guide hopper. The feeding hopper is movably positioned above the bag-taking mechanism. The bag-taking mechanism includes a steering block, a guide rod, and a moving block. The steering block is hinged to the machine base. One end of the guide rod is fixed with a suction cup seat, and a suction cup is provided on the suction cup seat. The other end of the guide rod passes through the steering block. The moving block is positioned on the guide rod and is located between the suction cup seat and the steering block. A drive assembly is connected to the moving block, and the drive assembly can drive the moving block to move.

[0058] Specifically, the feeding hopper is located directly above the bag-collecting mechanism. When the bag-collecting mechanism removes the packaging bag and moves it under the feeding hopper to unfold, the bottom of the feeding hopper is vertically aligned with the opening of the packaging bag for tea filling. The filled packaging bag then falls into the heat-sealing mechanism, which vents the air and seals the bag. The feeder can dispense loose tea leaves, which are conveyed in two directions by the first and second guide hoppers. The feeding hopper is connected to a chute on the machine platform and can move up and down, connecting the second guide hopper and bringing the lower part of the feeding hopper close to the opening of the packaging bag, allowing the tea leaves to be smoothly filled. In this process, the feeder in the feeding mechanism releases loose tea leaves into the first guide hopper, which guides and conveys the tea leaves using the interconnected first and second guide hoppers. The feeding hopper then moves downwards, connecting the bottom of the second guide hopper with the top of the feeding hopper, thus connecting the tea leaves and conveying them to the bag-collecting mechanism. This design shortens the time required for tea to be fed into packaging, has high smoothness, and therefore improves the packaging efficiency of filling flexible packaging with tea. When the drive assembly drives the moving block in a circular motion, the moving block can rotate the steering block via the guide rod, thereby changing the tilt angle of the guide rod. Therefore, the orientation of the suction cup holder changes with the movement of the moving block. The packaging bag is placed in a bag slot on the machine platform, located above the steering block, allowing the suction cup holder to change its orientation after picking up the bag, moving it below the feeding mechanism. When the drive assembly drives the moving block in a linear motion, the moving block causes the guide rod to extend and retract, expanding the range of motion of the suction cup holder, allowing the suction cup to extend and retract to pick up the packaging bag.

[0059] See Figure 2 As shown, the guide slide assembly includes parallel guide rails 215 and slide rails 216. The guide rail 215 passes through the electric slider 214, and a first connecting block 217 and a second connecting block 218 are fixed at both ends of the guide rail 215, respectively. A connecting plate 219 is fixed between the first connecting block 217 and the second connecting block 218. The slide rail 216 is provided on the side of the connecting plate 219 near the guide rail 215. The slide rail 216 is slidably connected to the electric slider 214. The connecting plate 219 is fixedly connected to the automatic packaging machine 1 and the packaging conveying mechanism 3.

[0060] In this embodiment, the first connecting block 217 and the second connecting block 218 are both bolted to the connecting plate 219 and are located on the same side of the connecting plate 219. The entire clamping assembly 21 can be fixed by fixing the connecting plate 219. The guide rail 215 can guide the electric slider 214 and support it. The slide rail 216 provides friction for the electric slider 214, allowing the electric slider to slide. This causes the electric slider 214 to drive the gripper assembly to move, realizing the picking and moving function of the clamping assembly 21. The connecting plate 219 can fix the whole assembly on the automatic packaging machine 1 and the packaging transmission mechanism 3, making the structure stable.

[0061] Furthermore, the connecting plate 219 is provided with two mounting brackets for fixing the connecting plate 219, and the two mounting brackets are located at both ends of the connecting plate 219 respectively.

[0062] Specifically, both mounting brackets are located on the side of the connecting plate 219 opposite to the slide rail 216 and can be fixed to the conveying assembly 31 and the machine base respectively. The mounting bracket is an L-shaped metal frame, which is fixed to the connecting plate 219 and the machine base by bolts, and the connecting plate 219 is perpendicular to one side of the machine base. In this way, the clamping assembly 21 is fixed as a whole and the clamping assembly 21 faces the heat sealing mechanism, which is convenient for clamping tea bags.

[0063] See Figure 2 As shown, the gripper assembly includes a gripper cylinder 211 and a gripper 212. The gripper 212 is mounted on the gripper cylinder 211, and the shaft end of the telescopic cylinder 213 is fixedly connected to the side of the gripper cylinder 211 opposite to the gripper 212.

[0064] In this embodiment, the gripper cylinder 211 can be configured as a finger gripper cylinder 211, with one side of it fixedly connected to the gripper 212 relative to the telescopic cylinder 213. Therefore, the gripper 212 can be used to grip the tea bag under the drive of the telescopic cylinder 213. When gripping, the gripper 212 contacts one end of the tea bag's seal and moves by gripping the side of the tea bag that does not contain tea leaves, so that the side containing tea leaves faces downwards.

[0065] See Figure 5 As shown, the detection component 33 also includes a third detection element 333 and a fourth detection element 334, both of which are located above the third conveyor belt 313. The packaging transmission mechanism 3 is also provided with a speed regulator 34, which is electrically connected to the detection component 33, the first drive element 4, the second drive element 5 and the third drive element 6.

[0066] In this embodiment, the first detection element 331, the second detection element 332, the third detection element 333, and the fourth detection element 334 are all infrared sensors. The PLC controller is equipped with a signal analysis and processing section. Based on the signal analysis of the detection component 33, the speed of the material moving on the conveyor belt is analyzed, thereby controlling the speed regulator 34 to adjust the rotation speed of the first drive element 4, the second drive element 5, and the third drive element 6, and then controlling the conveying speed of the first conveyor belt 311, the second conveyor belt 312, and the third conveyor belt 313 respectively, thereby adjusting the moving speed of the tea bag to achieve the adjustment of the speed of multi-stage conveying.

[0067] Example 3

[0068] This embodiment is an improvement on embodiment 2. Furthermore, the third driving component 6 includes a forward and reverse motor, which drives the first conveyor belt 311 to reverse when it receives a fault signal.

[0069] In this embodiment, if the tea packaging quick sorting device is installed in the production line, the forward and reverse motor rotates forward during normal operation. At this time, the first conveyor belt 311 will transport the tea bags to the second conveyor belt 312. When the equipment at the back end of the production line malfunctions and sends a fault signal, the PLC controller receives the fault signal and sends a control signal. The forward and reverse motor will receive the control signal and reverse, so that the first conveyor belt 311 transports the material in reverse, stopping the continuous input of tea bags to the back end from the source, thus preventing material blockage.

[0070] See Figure 6 As shown, multiple baffles 7 are fixed on the material box 321. The bottom of the multiple baffles 7 is inclined towards the inside of the material box 321 and connected to the opening edge of the material box 321.

[0071] In this embodiment, multiple baffles 7 are arranged circumferentially on the opening of the material box 321. Specifically, the baffles 7 are slightly higher than the upper surface of the third conveyor belt 313. The conveying assembly 31 can guide the tea bags into the material box 321 along the baffles 7 on both sides of the material box 321. At the same time, the bottom of the multiple baffles 7 moves towards the inside of the material box 321 to form an inverted cone shape, which can enlarge the top opening of the material box 321 to facilitate the entry of tea bags.

[0072] Furthermore, the conveying assembly 31 has skirts on both sides, and the bottom of the skirts is fixed to the conveying assembly 31.

[0073] Specifically, the skirt is made of plastic vertical plates, which helps to prevent tea bags from slipping off the side during the conveying process and ensures that the tea bags can be transported stably along the center line of the conveyor belt. The baffles 7 on both sides of the material box 321 are connected to the skirt, which can ensure that the tea bags enter the material box 321 smoothly.

[0074] Furthermore, a mounting bracket is installed on the conveying assembly 31, and the detection assembly 33 is mounted on the mounting bracket.

[0075] Specifically, the fixing frames are evenly distributed above the second conveyor belt 312 and the third conveyor belt 313. The bottom of the fixing frames is connected to the skirt of the second conveyor belt 312 and the third conveyor belt 313. The top of the fixing frames is used to fix and install the detection components 33. This facilitates the installation and removal of the detection components 33 and allows the detection components 33 to be located above the conveyed tea bags. The close-range setting helps to improve the recognition accuracy.

Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
