They lack a dedicated design to match the production process of fully biodegradable bamboo shoe materials, and cannot achieve precise material mixing and continuous conveying. They require additional independent mixing equipment, which increases the length of the production line and makes the process connections cumbersome. In addition, human error is prone to occur in the manual weighing process, and the maintenance cost of mechanical feeding equipment is high. Overall, this results in low production efficiency and high costs. Therefore, we need to provide a dedicated feeding system for the production of fully biodegradable bamboo shoe materials.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-3 This utility model provides a technical solution: a special feeding system for the production of fully degradable bamboo shoe materials, comprising: The system consists of a first draft fan 1, a second draft fan 2, a secondary silo 3, and a primary silo 4. The first draft fan 1 is installed at the inlet of the primary silo 4 to draw fully biodegradable bamboo shoe material into the primary silo 4. The second draft fan 2 is installed at the outlet of the primary silo 4, and the discharge end of the second draft fan 2 is connected to the secondary silo 3. A mixer 5 is provided between the primary silo 4 and the second draft fan 2.

[0016] The first induced draft fan 1 includes a first induced draft fan 11 and a first feeding air duct 12. The first induced draft fan 11 is connected to the primary material silo 4 through the first feeding air duct 12, and a feed pipe 6 is provided on one side of the first induced draft fan 11. Specifically, by integrating primary silo 4, secondary silo 3, weighing and mixing equipment, and a dedicated exhaust fan, the system achieves precise material proportioning, mixing, and continuous conveying in one integrated system. This eliminates the need for additional independent mixing equipment, significantly shortens the production line length, simplifies process connections, reduces equipment investment and maintenance costs, avoids errors from manual weighing, and improves material proportioning accuracy by relying on the system's automated weighing and conveying functions. This ensures the stability of the production quality of fully degradable bamboo shoe materials, reduces energy consumption and environmental risks, optimizes the exhaust fan operating parameters, and designs a dedicated conveying structure to reduce energy consumption to meet carbon neutrality requirements. At the same time, it prevents materials from absorbing water and deteriorating, reducing the generation of waste materials.

[0017] The second induced draft device 2 includes a second induced draft fan 21 and a second feeding air duct 22. The second induced draft fan 21 is connected to the mixer 5 through an installation pipe, and the second induced draft fan 21 is connected to the secondary silo 3 through the second feeding air duct 22. Furthermore, the outlet of the first induced draft fan 11 is sealed to one end of the first feeding duct 12 via a flange, and the other end of the first feeding duct 12 is welded and fixed to the inlet at the top of the primary silo 4. A flanged feed pipe 6 is welded to the inlet of the first induced draft fan 11, and a polytetrafluoroethylene anti-sticking layer is pasted on the inner wall of the feed pipe 6. The first induced draft fan 11 is a variable frequency induced draft fan, which is electrically connected to an external PLC controller and can adjust the operating frequency in the range of 10-40Hz. The feed pipe 6 is protected from bamboo material fibers sticking to the pipe wall by the anti-sticking layer. The first induced draft fan 11 controls the frequency through the PLC, and in conjunction with the sealed connection of the first feeding duct 12, it accurately controls the material suction speed and amount, ensuring that the material is stably conveyed to the primary silo 4. It forms a conveying and metering coordination with the weighing device 42 in the primary silo 4, avoiding excessive or insufficient material conveying.

[0018] The primary silo 4 includes a storage tank 41, a weighing device 42, and a control valve pipe 43. The discharge end of the first feeding air duct 12 is equipped with four weighing devices 42. The bottom of the weighing device 42 is equipped with a storage tank 41. The bottom of the storage tank 41 is connected to the mixer 5 through the control valve pipe 43. It should be noted that the air inlet of the second induced draft fan 21 is connected to one end of the installation pipe via a thread, and the other end of the installation pipe is connected to the discharge port of the mixer 5. The air outlet of the second induced draft fan 21 is welded to one end of the second feeding air duct 22, and the other end of the second feeding air duct 22 is sealed to the inlet of the top of the secondary silo 3 via a sealing ring. The second feeding air duct 22 is made of 304 stainless steel, and the inner diameter of the duct gradually increases from the air inlet to the air outlet. The quick-release buckle of the installation pipe facilitates the cleaning and maintenance of the mixer 5. The gradual inner diameter design of the second feeding air duct 22, combined with the air force of the second induced draft fan 21, reduces the impact and accumulation of materials in the duct, and realizes the smooth delivery of the mixed materials to the secondary silo 3, forming a connection between mixing and conveying with the secondary silo 3, and avoiding secondary agglomeration of materials.

[0019] The bottom of the secondary silo 3 is equipped with a heating agitator 7, which includes a conveying pipe 71 and a heater 72. The bottom of the secondary silo 3 is connected to a conveying pipe 71 through a feed pipe 6, and a heater 72 is provided on one side of the conveying pipe 71. It is worth noting that a heating agitator 7 is provided at the bottom of the secondary silo 3. The heating agitator 7 includes a conveying pipe 71 and a heater 72. The discharge port at the bottom of the secondary silo 3 is connected to one end of the feed pipe 6 through a flange. The other end of the feed pipe 6 is welded to the feed end of the conveying pipe 71. The conveying pipe 71 is made of double-layer stainless steel pipe (inner layer 304 stainless steel, outer layer insulation cotton). The heater 72 is an electromagnetic heater 72, which is wound and fixed on the outer layer of the conveying pipe 71 and electrically connected to an external PLC controller. It can control the heating temperature between 30-60℃. The material stored in the secondary silo 3 enters the conveying pipe 71 through the feed pipe 6. The heater 72 controls the temperature through the PLC. In conjunction with the double-layer insulation structure of the conveying pipe 71, the bamboo material is preheated at a low temperature to ensure the temperature adaptability of the material for subsequent processing.

[0020] The conveying pipe 71 is provided with a conveying component 8 for material conveying. The conveying component 8 includes a driver 81 and a screw conveyor 82. The screw conveyor 82 is rotatably installed in the conveying pipe 71. The driver 81 for rotating the screw conveyor 82 is provided on one side of the conveying pipe 71. The screw conveyor 82 is made of nylon and is rotatably mounted on the inner wall of the conveying pipe 71 through bearings at both ends. The driver 81 is a stepper motor, which is connected to one end of the screw conveyor 82 through a coupling. The driver 81 is electrically connected to an external PLC controller. A discharge valve is provided on one side of the bottom of the conveying pipe 71. The discharge valve is a manual ball valve, which is welded to the conveying pipe 71. The driver 81 controls the speed through the PLC, driving the screw conveyor 82 to rotate at a uniform speed, and smoothly pushing the preheated material to the discharge valve. The nylon screw conveyor 82 avoids scratching the inner wall of the conveying pipe 71 and reduces material adhesion, ensuring a stable material discharge.

[0021] The induced draft fan, weighing device 42, control valve pipe 43, agitator and driver 81 in the conveying component 8 involved in this application are all implemented using existing mature technologies and are connected to an external PLC controller and power supply. This is a conventional technical means in this field, so its specific circuit connection, control logic and working process will not be described in detail.

[0022] The device starts the first induced draft fan 11 to send the material through the feed pipe 6 into the first feeding pipe, and then sends the material into four storage tanks 41. A weighing device 42 is installed on the top of the storage tank 41 to weigh the material, and a control valve pipe 43 is installed at the bottom of the storage tank 41. Through an external PLC controller, the material in the storage tank 41 is sent into the mixer 5. The mixer 5 is connected to the second induced draft fan 21 through an installation pipe, which can send the material in the mixer 5 into the second feeding air pipe 22, and then to the secondary silo 3. The bottom of the secondary silo 3 is connected to the conveying pipe 71 through a control valve, and the material can enter the conveying pipe 71. A heater 72 is installed on one side of the conveying pipe 71 to heat the material in the conveying pipe 71. The starting driver 81 drives the spiral conveyor 82 to rotate, which can discharge the material in the conveying pipe 71. A discharge valve pipe is installed on one side of the bottom of the conveying pipe 71 for material discharge.
