Technical Field

[0001] This utility model relates to the technical field of tea cake pressing equipment, and in particular to a tea cake pressing device with automatic weighing function. Background Technology

[0002] A tea cake press is a device that presses loose tea into cakes. Its main function is to compress tea, making it easier to store, transport, and sell, while also aiding in aging and quality improvement. When using a tea cake press, an appropriate amount of loose tea is placed into a mold, and then pressure is applied to the tea using a pressing device to shape it into a cake. The published patent document "CN222916938U" discloses a tea cake press that integrates tea feeding, steaming, pressing, and conveying, improving equipment integration, reducing manual labor, and increasing production efficiency. However, this solution does not pre-weigh each batch of tea; therefore, weighing after pressing and discarding substandard tea not only wastes tea but also increases production costs. Therefore, this invention proposes a tea cake pressing device with an automatic weighing function before pressing. Utility Model Content

[0020] like Figures 1 to 5 As shown, the pressing device with automatic weighing function proposed in this utility model includes a frame 1 and a storage hopper 2 installed on the top of the frame 1. A vibrating feeding plate 3 is also provided at a corresponding position below the storage hopper 2. A material trough 4 is provided at the discharge port of the vibrating feeding plate 3. A weighing component 5 and a conveyor belt 6 are installed at the bottom of the material trough 4 for weighing and conveying the tea leaves. A fixing frame for installing the conveyor belt 6 is provided above the guide plate 7. The guide plate 7 is inclined. A tea pressing component 9 for pressing tea cakes is provided at the discharge end of the tea steaming chamber 8. A discharge channel is opened at the discharge end of the tea pressing component 9 on the frame 1. A collection frame 10 located below the frame 1 is provided below the discharge channel. Specifically, the conveyor... The drive end of conveyor belt 6 is a forward and reverse motor. Below conveyor belt 6, there are guide plates 7 and steaming chamber 8. If the weighing sensor 500 weighs the tea leaves within ±0.3g of the set amount, it means that the tea leaves meet the production requirements. The tea leaves are conveyed by the weighing component 5 to the steaming chamber 8 for steaming, and then pressed into cakes by the pressing component 9. Finally, they are conveyed to the collection frame 10 for centralized collection. The specific technology and equipment used for steaming and pressing are based on the technology in patent "CN222916938U", which will not be elaborated here. If the weighing weight of the tea leaves is greater than ±0.3g, the conveyor belt 6 is driven in reverse to convey the tea leaves that do not meet the weight requirements to the guide plate 7 for centralized collection, which is convenient for subsequent recycling and reuse.

[0021] Combination Figure 4 and Figure 5 As shown, the weighing assembly 5 includes a material carrier plate 54 rotatably mounted on the bottom discharge port of the material trough 4. A push rod motor 56 is also installed below the material trough 4. The output end of the push rod motor 56 is fixedly connected to a clamping plate 55 that is engaged with the material carrier plate 54. A push-pull opening 40 is provided on the side of the material trough 4 for the clamping plate 55 to pass through. A groove is provided below the push-pull opening 40 for the push rod motor 56 to be installed, and a shock-absorbing pad is provided in the groove to reduce the impact of motor vibration on the metering accuracy. A clamping plate is provided at the end of the material carrier plate 54 for the clamping plate 55 to be engaged. The groove 540 has anti-slip textures on its inner wall to ensure stable transmission. A rotating shaft 53 is installed through the other end of the material carrier plate 54. A drive motor 52 is fixedly connected to the outer wall of the material trough 4 at one end of the rotating shaft 53. A weighing sensor 500 is installed on the upper surface of the material carrier plate 54. The sensor surface is covered with an anti-stick coating to prevent tea residue. A PLC controller 51 is also installed on the side wall of the material trough 4. The PLC controller 51 is electrically connected to the control terminal of the drive motor 52. The weighing sensor 500 is communicatively connected to the PLC controller 51. Real-time data transmission is achieved through wired communication to ensure synchronous response of weighing and sorting actions.

[0022] In this embodiment, loose tea leaves in the storage hopper 2 enter the vibrating feeding tray 3. This component adopts a spiral feeding structure and accurately controls the amount of tea leaves fed at one time according to preset parameters to avoid excessive accumulation or insufficient feeding of tea leaves, ensuring that the tea leaves fall smoothly into the material trough 4 below. A weighing sensor 500 is installed on the upper surface of the loading plate 54 at the bottom of the material trough 4. After the tea leaves fall in, the sensor immediately collects weight data and transmits the data to the PLC controller 51 in real time through wired communication. The anti-stick coating on the surface of the sensor can prevent tea residue from affecting the measurement accuracy and ensure the accuracy of the weighing data each time. After receiving the weighing data, the PLC controller 51 compares it with the preset weight threshold. When the weight of the tea leaves is within the preset value ±0.3g error range, it is determined to be a qualified product. The controller sends a positive drive signal to the push rod motor 56 and the conveyor belt 6. The output end of the push rod motor 56 pushes the card plate 55 to disengage from the card slot 540. The drive motor 52 drives the material plate 54 to rotate, so that the tea leaves are fed to the conveyor belt 6. The conveyor belt 6 drives the tea leaves in the steaming chamber 8 to steam for subsequent processing. When the weight of the tea leaves exceeds the above error range, it is determined to be a defective product. The controller sends a reverse drive signal, and the conveyor belt 6 reverses the drive to drop the tea leaves onto the guide plate 7 for recycling.

[0023] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
