Description

Technical Field

[0001] This utility model relates to the field of tea production technology, specifically to an automatic tea feeding mechanism. Background Technology

[0002] During the production and packaging process, tea needs to be transported through a feeding mechanism. Generally, the tea is first stored in a hopper, and when feeding is needed, the valve body set at the bottom of the hopper is opened, and the tea can fall through the pipe.

[0003] However, in most existing tea feeding mechanisms, the tea leaves, being rod-shaped, are prone to crossing each other during the feeding process, which can easily cause blockages and prevent the tea leaves from being fed properly, thus reducing the production efficiency of the device. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic tea feeding mechanism to solve the technical problems mentioned in the background art.

[0005] The technical problem to be solved by this utility model can be achieved through the following technical solution:

[0006] An automatic tea feeding mechanism,

[0007] It includes a feeding rack, the top of which is provided with a hopper for storing tea leaves, and the bottom of which is provided with a feeding square tube for discharging tea leaves;

[0008] It also includes an anti-clogging component for clearing tea leaves. The anti-clogging component includes several sets of pneumatic pipes installed inside the feeding rack, with one end of the pneumatic pipe penetrating the feeding rack, a manifold set at the penetrating end of the pneumatic pipe, several sets of exhaust holes opened at the bottom of the pneumatic pipe, a cross-shaped material distribution plate rotatably installed inside the feeding square tube, and a protective plate installed inside the feeding square tube that matches the cross-shaped material distribution plate. The protective plate is an arc-shaped plate with gas channels opened inside the protective plate, and several sets of guide holes for exhausting gas are opened on the top side wall of the protective plate and communicate with the gas channels.

[0009] Preferably, the end face of the protective plate opposite to the rotation direction of the gas flow channel is an inclined surface, and the output end of the guide hole is provided with a dust cover.

[0010] Preferably, three sets of baffles are provided at the top edge of the hopper, and a vertical screen is inclinedly provided at the top of the hopper.

[0011] Preferably, a magnetically controlled air valve communicating with a gas flow channel is provided on the side wall of the feeding square tube, an annular plate connected to a cross-shaped material distribution plate is rotatably provided on the side wall of the feeding square tube, and a pressure switch is provided on the side wall of the feeding square tube with the annular plate, and the pressure switch is electrically connected to the magnetically controlled air valve.

[0012] Preferably, four sets of pressure plates are equidistantly distributed on the side of the annular plate near the pressure switch, and the side of the pressure plates near the pressure switch is inclined along the rotation direction of the annular plate.

[0013] Preferably, the feeding square tube is provided with a servo motor on one side of the annular plate for driving the cross-shaped feeding plate to rotate.

[0014] Preferably, the unloading rack is equipped with a pressurized air pump for supplying air.

[0015] Preferably, the output end of the pressurized air pump is provided with a three-way pipe, and the output end of the three-way pipe is respectively provided with an air supply hose for connecting the manifold and the magnetic control air valve.

[0016] Preferably, a recycling trough is slidably disposed on one side of the top of the hopper, and the recycling trough is located below the lowest end of the vertical screen.

[0017] Preferably, the top side of the unloading rack is provided with a T-shaped chute for guiding and limiting the recycling tank, and the top of the recycling tank is provided with a T-shaped guide rail that matches the T-shaped chute.

[0018] The beneficial effects of this utility model are:

[0019] 1. In this utility model, the compressed air generated by the pressurizing air pump is delivered to the manifold through the three-way pipe and the air delivery hose, and then distributed to each pneumatic pipe by the manifold. The exhaust hole opened on the pneumatic pipe sprays the airflow downward into the hopper and the inside of the feeding square pipe. The gas flows between the tea leaves during the feeding process, so that there are certain gaps between them, ensuring that the tea leaves also have a certain fluidity, thereby avoiding blockage and ensuring that the tea leaves can be fed smoothly.

[0020] 2. In this utility model, the protective plate can flatten the highest end of the cross-shaped material distribution plate, thereby avoiding excessive tea leaves in the storage space, which would cause excessive compression during the feeding process and breakage of the tea leaves. This further protects the tea leaves. In addition, the protective plate has gas flow channels and guide holes inside and on the end face. The gas blown out from the end face of the protective plate can further prevent the tea leaves from being squeezed against the end face of the protective plate during quantitative feeding, thus preventing the tea leaves from breaking.

[0027] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0028] like Figure 1-4 As shown, an automatic tea feeding mechanism is described.

[0029] The device includes a feeding rack 1, a hopper 2 for storing tea leaves at the top of the feeding rack 1, three sets of baffles 3 at the top edge of the hopper 2, a vertical screen 4 at the top of the hopper 2, and a feeding square tube 5 at the bottom of the hopper 2 for discharging tea leaves. The feeding rack 1 serves as the supporting frame of the entire mechanism, providing a foundation for the installation and positioning of other components and ensuring the overall stability of the device during operation. The baffles 3 prevent tea leaves from spilling outside the hopper 2 during the process of adding tea leaves to the hopper 2, ensuring that all tea leaves enter the hopper 2 and reducing waste. The vertical screen 4 can perform preliminary screening of the tea leaves added to the hopper 2, removing any larger impurities or non-compliant tea stalks, thereby improving the quality of the tea leaves. The feeding square tube 5 guides the tea leaves to fall smoothly from the hopper 2.

[0030] It also includes an anti-clogging component for clearing tea leaves. The anti-clogging component includes several sets of pneumatic pipes 6 installed inside the feeding rack 1, with one end of each pneumatic pipe 6 penetrating the feeding rack 1; a manifold 7 located at the penetrating end of the pneumatic pipe 6; several sets of exhaust holes 8 at the bottom of the pneumatic pipe 6; a cross-shaped dividing plate 9 rotatably installed inside the feeding square tube 5; a protective plate 10 matching the cross-shaped dividing plate 9, installed inside the feeding square tube 5; the protective plate 10 is an arc-shaped plate; a gas flow channel 11 is opened inside the protective plate 10; and several sets of exhaust guide holes communicating with the gas flow channel 11 are opened on the top side wall of the protective plate 10. A magnetically controlled air valve 12 communicating with the gas flow channel 11 is installed on the side wall of the feeding square tube 5. A magnetically controlled air valve 12 rotatably installed on the side wall of the feeding square tube 5 is also connected to the cross-shaped dividing plate 9. The annular plate 13 is connected to the material sorting plate 9. The material discharge square tube 5 is provided with a pressure switch 14 on the side wall of the annular plate 13, and the pressure switch 14 is electrically connected to the magnetic control air valve 12. Four sets of pressure plates 15 are equidistantly distributed on the side of the annular plate 13 near the pressure switch 14, and the side of the pressure plates 15 near the pressure switch 14 is inclined along the rotation direction of the annular plate 13. The material discharge rack 1 is provided with a pressurizing air pump 17 for air supply. The output end of the pressurizing air pump 17 is provided with a three-way pipe 18. The output end of the three-way pipe 18 is respectively provided with air delivery hoses 19 for connecting the manifold 7 and the magnetic control air valve 12. During material discharge, the compressed air generated by the pressurizing air pump 17 is delivered to the manifold 7 through the three-way pipe 18 and the air delivery hoses 19, and then distributed by the manifold 7 to each pneumatic tube. 6. The exhaust port 8 on the pneumatic pipe 6 sprays air downwards into the hopper 2 and the inside of the feeding square tube 5. The gas flows between the tea leaves during the feeding process, creating a certain gap between them, ensuring that the tea leaves also have a certain degree of fluidity, thereby avoiding blockage and ensuring that the tea leaves can be fed smoothly. The rotating cross-shaped dispensing plate 9 can play a role in quantitative dispensing. A pressure sensor can be installed on it. When the tea leaves in the storage space enclosed by the cross-shaped dispensing plate 9 and the feeding square tube 5 accumulate to a certain weight, the pressure sensor can control the servo motor 16 to rotate, thereby realizing quantitative dispensing. When the cross-shaped dispensing plate 9 rotates, the top of the protective plate 10 is aligned with the tangent direction of the highest point of the cross-shaped dispensing plate 9. The protective plate 10 can control the highest point of the cross-shaped dispensing plate 9. The ends are scraped flat to prevent excessive tea leaves from being trapped in the storage space, which could lead to over-compression and breakage during feeding. This further protects the tea leaves. Furthermore, the protective plate 10 has gas channels 11 and guide holes inside and on its end face. Gas blown from the end face of the protective plate 10 further prevents the tea leaves from being compressed against the end face of the protective plate 10 during quantitative feeding, thus preventing breakage. When the cross-shaped feeding plate 9 rotates, it synchronously drives the annular plate 13 to move. The pressure plate 14 on the annular plate 13 periodically presses the pressure switch 15. Whenever the cross-shaped feeding plate 9 feeds, the pressure plate 14 presses the pressure switch 15, which controls the magnetic control air valve 12 to open, allowing the pressurized air pump 17 to supply air to the protective plate 10. After feeding is complete...When the pressure plate 14 moves away from the pressure switch 15, the magnetic control air valve 12 closes. At this time, the cross-shaped material distribution plate 9 stops rotating, allowing the tea leaves in the feeding square tube 5 sufficient time to enter the storage space.

[0031] In this embodiment, specifically, the end face of the protective plate 10 opposite to the rotation direction of the gas flow channel 11 is an inclined surface, and a dust cover is provided at the output end of the guide hole.

[0032] In this embodiment, specifically, a servo motor 16 for driving the cross-shaped material distribution plate 9 to rotate is provided on one side of the feeding square tube 5 relative to the annular plate 13. The servo motor 16 has high precision and good stability, ensuring that the cross-shaped material distribution plate 9 can rotate at the set speed and direction, thereby realizing the quantitative feeding of tea leaves.

[0033] In this embodiment, specifically, a recycling trough 20 is slidably provided on one side of the top of the hopper 2, and the recycling trough 20 is located below the lowest end of the vertical screen 4. A T-shaped chute 21 is provided on one side of the top of the unloading rack 1 to guide and limit the recycling trough 20. A T-shaped guide rail 22 matching the T-shaped chute 21 is provided on the top of the recycling trough 20. The recycling trough 20 is used to collect the impurities screened out by the vertical screen 4, making it convenient for workers to recycle the tea leaves mixed in the impurities. The T-shaped chute 21 and the T-shaped guide rail 22 cooperate with each other to facilitate the installation and disassembly of the recycling trough 20.

[0034] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0035] The working principle of this utility model is as follows: First, tea leaves are added to the hopper 2. The vertical sieve 4 performs preliminary screening of the tea leaves to remove impurities. The impurities fall into the recycling tank 20. Then, the servo motor 16 is started to drive the cross-shaped distributing plate 9 to rotate, distributing the tea leaves so that they fall evenly. When the tea leaves fall to the cross-shaped distributing plate 9, the compressed air generated by the pressurized air pump 17 is delivered to the manifold 7 and the pneumatic pipe 6 through the three-way pipe 18 and the air delivery hose 19. The pneumatic pipe 6 sprays gas downward through the exhaust hole 8, giving the tea leaves a certain degree of fluidity and preventing them from clogging the feeding square pipe 5. When the cross-shaped distributing plate 9 rotates to feed equal amounts of tea leaves, the annular plate 13 rotates, causing the pressure plate 14 to periodically contact the pressure switch 15, triggering the magnetic control air valve 12 to open, allowing gas to be blown out from the end face of the protective plate 10. This further prevents the tea leaves from being squeezed against the end face of the protective plate 10 during quantitative feeding, thus preventing the tea leaves from breaking.

[0036] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
