Description

Technical Field

[0001] This utility model relates to the field of agricultural product processing, and in particular to a metering fine-tuning device for a tea bag packaging machine. Background Technology

[0002] Tea bags are a very convenient form of tea, as they encapsulate tea leaves in small bags, making brewing simple and quick.

[0003] Currently, to ensure that the amount of tea leaves in each tea bag remains consistent and meets expected standards during the processing of tea bags, strict control over the measurement of tea bags is necessary. This is not only a key factor in product quality and consumer satisfaction, but also an important guarantee for enterprise production efficiency, cost control, and brand image.

[0004] However, most current tea bag packaging machines rely on relatively simple mechanical adjustment devices for their metering systems. For example, they use centralized weighing followed by sorting and feeding. This method requires multiple motors to drive different conveyor devices to distribute the tea leaves to various packaging areas. However, the fixed sorting and feeding pattern makes it difficult to quickly adapt to the processing needs of different batches or types of tea. When it is necessary to change to different types or densities of tea, the parameters of the entire system must be readjusted, which increases the difficulty of operation and time costs.

[0005] Therefore, there is an urgent need to propose a metering fine-tuning device for a tea bag packaging machine. Utility Model Content

[0006] In order to overcome the shortcomings of the existing technology, this utility model provides a metering fine-tuning device for a tea bag packaging machine.

[0007] The technical solution of this utility model is as follows: a metering fine-tuning device for a tea bag packaging machine, comprising a frame, a loading hopper, a discharging hopper, a cover plate, a handle, a conveying pipe, a motor, a screw conveyor, a feeding pipe, a weighing frame, a guide rail, a baffle, a weighing sensor, an electric cylinder, and a collecting hopper. Two loading hoppers are arranged close together on the rear top of the frame. The bottom of the loading hoppers is connected to the discharging hopper. A cover plate is embedded and hinged to the top of the loading hoppers. A handle is provided on the outward side of the cover plate. The bottom of the discharging hopper is connected to the conveying pipe. A motor is installed outside the conveying pipe, and the output shaft of the motor extends into the conveying pipe. A screw conveyor is rotatably arranged inside the conveying pipe. The conveyor paddle and the screw conveyor paddle are connected to the output shaft of the motor. The bottom of the front of the conveyor pipe is connected to the discharge pipe. Weighing frames are set on both sides of the upper part of the frame. Each weighing frame is connected to the corresponding discharge pipe above. Guide rails are set on both sides of the lower part of the weighing frame. A baffle is slidably set between the guide rails at the bottom of each weighing frame. The baffle covers the opening at the bottom of the weighing frame. A weighing sensor is installed at the bottom of the baffle. Electric cylinders are installed on both sides of the lower rear part of the frame. The extension and retraction ends of the electric cylinders are connected to the rear end of the corresponding baffle at the front. A collection hopper is set on the front side of the lower part of the frame. The opening at the top of the collection hopper corresponds to the bottom of the two baffles.

[0008] In a preferred embodiment of this utility model, the lower part of the collecting hopper is arranged in an inclined shape with the four sides converging.

[0009] In a preferred embodiment of the present invention, an inclined tube is also included, and the gathering part at the bottom of the collecting hopper is connected to the inclined tube.

[0010] In a preferred embodiment of the present invention, rubber pads are also included, with each support foot of the frame having a rubber pad at its bottom.

[0011] In a preferred embodiment of this utility model, a protective cover is also included, and the frame is covered with a protective cover.

[0012] In a preferred embodiment of this utility model, a control panel is also included. The control panel is installed on the outside of the protective cover, and the control panel is electrically connected to the motor, the weighing sensor and the electric cylinder.

[0013] In a preferred embodiment of the present invention, a receiving frame is further included, wherein the receiving frame is snapped between the top of each support leg of the frame, and the receiving frame is located below the opening at the bottom of the inclined tube and the collecting hopper.

[0014] The beneficial effects of this utility model are as follows: 1. This utility model uses data from a weighing sensor to calculate the required amount of tea leaves using a control panel, and finely adjusts the position of the baffle by using the telescopic end of an electric cylinder to ensure that the amount of tea leaves in each tea bag meets the preset standard, which significantly improves the consistency of tea filling and reduces batch-to-batch differences.

[0015] 2. The design of this utility model, through the electric cylinder and the screw conveyor, allows the system to respond quickly and adjust the material flow rate, ensuring that each filling can quickly reach the expected weight, shortening the processing time of a single tea bag and increasing the output per unit time.

[0016] 3. By designing the loading hopper into two closely spaced hoppers, this utility model can classify and load tea according to different batches or types, improving production flexibility and meeting the processing needs of various tea varieties.

[0017] 4. This utility model, through the inclined arrangement of the lower part of the hopper converging on all four sides and the connected inclined pipe, can guide the tea leaves to be discharged quickly and centrally, reducing the workload of cleaning up residues. Attached Figure Description

[0025] Although this invention may be described with respect to a particular application or industry, those skilled in the art will recognize its broader applicability. Those skilled in the art will understand that terms such as "above," "below," "upward," "downward," etc., are used to describe the drawings and not to indicate a limitation on the scope of the invention as defined by the appended claims. Any numerical designations such as "first" or "second" are merely illustrative and not intended to limit the scope of the invention in any way.

[0026] Example: A metering fine-tuning device for a tea bag packaging machine, such as... Figures 1-6As shown, the device includes a frame 1, a loading hopper 2, a discharging hopper 21, a cover plate 3, a handle 31, a conveying pipe 4, a motor 5, a screw conveyor 6, a discharge pipe 7, a weighing frame 8, a guide rail 9, a baffle 10, a weighing sensor 11, an electric cylinder 12, and a collecting hopper 13. The frame 1 serves as the basic support structure for the entire device, ensuring the stable installation and operation of all components. Two closely spaced loading hoppers 2 are located on the top rear side of the frame 1 for loading tea leaves or other herbal materials to be packaged. Their close proximity allows for categorized loading according to different batches or types of tea, improving production flexibility. The bottom of the loading hopper 2 is connected to the discharging hopper 21 via a flange. The tea leaves in the loading hopper 2 are guided into the conveying pipe 4, ensuring that the material moves forward evenly and continuously. A cover plate 3 is hinged and embedded at the top of the loading hopper 2. A handle 31 is screwed onto the outward side of the cover plate 3, assisting the operator in easily opening and closing the cover plate 3 for convenient material addition. The bottom of the discharge hopper 21 is connected to the conveying pipe 4 via a flange. A motor 5 is installed outside the conveying pipe 4, and the output shaft of the motor 5 extends into the conveying pipe 4. A rotating screw conveyor 6 is installed inside the conveying pipe 4, and the screw conveyor 6 is connected to the output shaft of the motor 5 via a coupling. The front bottom end of the conveying pipe 4 is connected to the discharge pipe 7 via a flange. The tea leaves are gradually pushed into the discharge pipe 7 by the rotation within the conveying pipe 4. The screw conveyor 6 ensures that the material moves forward evenly and continuously. Weighing frames 8 are installed on both sides of the upper part of the frame 1. The feed pipe 7 guides the tea leaves in the conveyor pipe 4 to the corresponding weighing frame 8, ensuring that the material falls accurately into the weighing area. Each weighing frame 8 is connected to the corresponding feed pipe 7 above. Guide rails 9 are bolted to both sides of the lower part of the weighing frame 8. A baffle 10 is slidably installed between the guide rails 9 at the bottom of each weighing frame 8. The guide rails 9 provide a sliding path for the baffle 10, ensuring that the baffle 10 moves smoothly and is accurately positioned. The baffle 10 covers the opening at the bottom of the weighing frame 8. A weighing sensor 11 is installed at the bottom of the baffle 10 by a bracket for real-time monitoring and recording of the weighing frame. The current weight within 8 ensures that the amount of tea leaves in each tea bag is highly consistent. Electric cylinders 12 are bolted to both sides of the lower rear part of the frame 1. The telescopic ends of the electric cylinders 12 are connected to the rear end of the corresponding front baffles 10 through pins. The electric cylinders 12 finely adjust the position of the baffles 10 through the telescopic ends to achieve precise control of the amount of tea leaves. A collection hopper 13 is set on the lower front side of the frame 1 through a bracket. The lower part of the collection hopper 13 is inclined in a four-sided converging shape. The opening of the upper part of the collection hopper 13 corresponds to the lower part of the two baffles 10. The collection hopper 13 collects tea leaves that meet the preset standards in the weighing frame 8. The inclined shape of the lower part helps to guide the tea leaves to quickly concentrate and discharge.

[0027] like Figure 6 As shown, it also includes an inclined tube 14. The gathering part at the bottom of the collecting hopper 13 is connected to the inclined tube 14 by welding, which can further guide the tea leaves to be discharged in a concentrated manner, reducing the workload of cleaning residues.

[0028] like Figure 6 As shown, it also includes rubber pads 15. Each support foot of the frame 1 is provided with rubber pads 15 by adhesive to provide sufficient friction, prevent the device from sliding during operation, and reduce noise.

[0029] like Figure 1 As shown, it also includes a protective cover 16. The frame 1 is covered with a protective cover 16 by bolts, which can protect the internal components from dust and other impurities and extend the service life of the equipment.

[0030] like Figure 1 As shown, it also includes a control panel 17. The control panel 17 is installed on the outside of the protective cover 16. The control panel 17 is electrically connected to the motor 5, the load cell 11 and the electric cylinder 12. Automated control is realized through the electrical connection of the motor 5, the load cell 11 and the electric cylinder 12.

[0031] like Figure 1 As shown, it also includes a receiving frame 18. The receiving frame 18 is snapped between the top of each support leg of the frame 1. The receiving frame 18 is located below the opening at the bottom of the inclined tube 14 and the collecting hopper 13, and can collect tea leaves that are accidentally spilled, preventing tea waste.

[0032] First, place the entire device at the designated installation point, ensuring that the rubber pads 15 at the bottom of each support leg of the frame 1 provide sufficient friction to prevent the device from sliding during operation. Then, connect the power to the electrical components such as the motor 5, electric cylinder 12, and control panel 17. Open the cover 3 and add the tea leaves or other herbal materials to be packaged via the handle 31. The loading hopper 2 is designed with two closely fitting hoppers, allowing for categorized loading according to different batches or types of tea. Before starting formal packaging, calibrate the weighing frame 8 by setting the expected tea weight standard via the control panel 17 and verifying it using a standard weight of known weight to ensure the accuracy of the weighing sensor 11. Adjust the telescopic end of the electric cylinder 12 via the control panel 17 to position the baffle 10 appropriately below the bottom opening of the weighing frame 8, covering the opening to prevent premature material drop. Start the motor 5 to drive the spiral conveyor 6 to rotate within the conveying pipe 4, gradually pushing the tea leaves entering from the discharge hopper 21 to the discharge pipe 7. The design of the conveyor paddle 6 ensures that the material moves forward evenly and continuously, avoiding blockages or irregular flow. When the tea leaves fall into the corresponding weighing frame 8 through the feed pipe 7, the weighing sensor 11 monitors and records the current weight in real time. Once the preset value is reached, the control system will immediately stop the motor 5 and keep the baffle 10 closed to prevent excess material from continuing to flow in. After the initial measurement is completed, the control system accurately calculates the amount of tea leaves to be adjusted based on the data fed back by the weighing sensor 11. If a slight deficiency is detected, the baffle 10 is slightly loosened (i.e., the extension end of the electric cylinder 12 is shortened) to allow a small amount of extra tea leaves to be added; conversely, the same applies. This micro-adjustment mechanism ensures that the amount of tea leaves in each tea bag is highly consistent. When the amount of tea leaves fully meets the requirements, the control system instructs the electric cylinder 12 to fully open the baffle 10, allowing the tea leaves in the weighing frame 8 to fall smoothly into the collection hopper 13 below. The lower part of the collection hopper 13 is set in an inclined shape with four sides converging and is connected to an inclined pipe 14, which helps to guide the tea leaves to quickly concentrate and discharge.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that variations may be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
