[0023] The following is combined with Figure 1-4 This application is described in further detail.

[0024] The present application embodiment discloses a high-precision screw conveying device for material production. Figure 1-4 , a high-precision screw conveying equipment for material production, comprising:

[0025] The main conveying mechanism includes a main screw conveyor 1, the main screw conveyor 1 is internally rotatably connected with a screw conveying rod 6, the screw conveying rod 6 is driven to rotate by a driving motor 5, the driving motor 5 is fixedly mounted on the outer wall of one end of the main screw conveyor 1, the output shaft end thereof passes through the main screw conveyor 1 and is fixedly connected to one end of the screw conveying rod 6, the outer shell of the main screw conveyor 1 is provided with a main screw conveyor feed port 3 and a main screw conveyor discharge port 4, the screw conveying rod 6 has a relatively large pitch and diameter, and is used to quickly convey materials to the transfer area;

[0026] The auxiliary conveying mechanism includes an auxiliary screw conveyor 2, which is fixedly connected to the outer wall of the main screw conveyor 1 at one end away from the driving motor 5. The auxiliary screw conveyor 2 is driven to rotate by the speed regulating motor 8. The top outer wall of the auxiliary screw conveyor 2 is fixedly connected with a shaft sleeve 7, and the shaft sleeve 7 is connected to the inside of the auxiliary screw conveyor 2. The output shaft of the speed regulating motor 8 passes through the shaft sleeve 7 and is fixedly connected to the top of the screw rod in the auxiliary screw conveyor 2. The feed port of the auxiliary screw conveyor 2 is connected to the main screw conveyor discharge port 4 of the main screw conveyor 1. The spiral blades on its screw rod have relatively small pitch and diameter, which are used to slowly and accurately convey the material conveyed from the main screw conveyor 1 to the subsequent process.

[0027] The main screw conveyor feed port 3 of the main screw conveyor 1 is connected to an external material storage device for receiving materials for conveying.

[0028] The auxiliary screw conveyor discharge port 9 of the auxiliary screw conveyor 2 leads to the subsequent packaging process link, and is used for high-precision conveying and packaging of materials.

[0029] The driving motor 5 and the speed regulating motor 8 are both electrically connected to an external control device, and the control device adopts a programmable logic controller.

[0030] A main screw material stop valve 11 is fixedly installed on the inner wall between the main screw conveyor 1 and the auxiliary screw conveyor 2. The main screw material stop valve 11 is located between the main screw conveyor 1 and the auxiliary screw conveyor 2. When the main screw conveyor 1 completes most of the work, the main screw material stop valve 11 closes its outlet, opens the auxiliary screw conveyor 2, and transports through the auxiliary screw conveyor 2.

[0031] A secondary screw material stop valve 10 is fixedly installed on the inner wall of the bottom of the secondary screw conveyor 2. The secondary screw material stop valve 10 can be used to finely cut off the material at the discharge end. When it is necessary to accurately control the discharge amount or switch the conveying path, the material can be quickly and effectively cut off. Both stop valves are electrically controlled and connected to the control system, and can be remotely or automatically controlled according to production needs.

[0032] The implementation principle of a high-precision screw conveying equipment for material production in an embodiment of the present application is as follows: first, the high-precision screw conveying equipment for material production is installed and debugged according to the design requirements to ensure that the components are firmly connected, the circuit connection between the external control device (not shown in the figure) and the drive motor and the speed regulating motor is normal, and the corresponding material conveying volume, motor speed and other parameters are preset in the control device.

[0033] The material enters the main screw conveyor 1 from a storage device such as a silo through the main screw conveyor feed port 3. The drive motor 5 drives the screw conveying rod 6 in the main screw conveyor 1 to operate at a preset higher speed. Due to the large pitch and large diameter spiral blades of the screw conveying rod 6, the material can be quickly transported toward the main screw conveyor discharge port 4 and reach the transfer area.

[0034] Next, the material coming out of the discharge port 4 of the main screw conveyor enters the auxiliary screw conveyor 2 through the feed port of the auxiliary screw conveyor (not shown in the figure), and the speed regulating motor 8 drives the internal screw rod (not shown in the figure) to rotate at a relatively slow speed according to the instruction of the control device. The screw rod in the auxiliary screw conveyor 2 relies on its small pitch and small diameter spiral blade to slowly and accurately convey the material out of the discharge port 9 of the auxiliary screw conveyor to supply the subsequent packaging process, etc., thereby realizing high-precision material transportation and ensuring that the material packaging accuracy meets the production requirements;

[0035] It is worth noting that the feed port of the auxiliary screw conveyor 2 is docked with the main screw conveyor discharge port 4 at the end of the main screw conveyor 1, so it is a re-fit connection. Therefore, only the main screw conveyor discharge port 4 is shown in the accompanying drawings, and the feed port of the auxiliary screw conveyor 2 is not shown.

[0036] During the entire operation of the equipment, the control device monitors the status of each link in real time, and dynamically adjusts the speed of the drive motor 5 and the speed regulating motor 8 according to the actual production progress, material transportation feedback and other information to ensure that the equipment is always in an efficient and high-precision material transportation working state.
