[0019] By adopting the above technical solution, the weighing rod drives the material to form a swirling flow through the guide vanes during the spiral ascent, which facilitates the rapid passage of the material through the discharge hole and thus improves the efficiency of material weighing.
[0020] Preferably, a sealing ring is provided at the bottom of the sealing ring, the sealing ring is disposed in the discharge hole, and the sealing ring abuts against the tapered portion.
[0021] By adopting the above technical solution, the sealing ring is inserted into the discharge hole, which further reduces material leakage and thus further improves the accuracy of material weighing.

[0023] 1. This application provides a sealing gasket at the conical part at the bottom of the funnel body, so that the weighing rod abuts against the sealing gasket when blocking the discharge hole, thereby reducing the wear on the conical part and the weighing rod during the weighing process, thus improving the service life of the conical part and the weighing rod, reducing material leakage, and improving the accuracy of the material weighing process.
[0024] 2. The weighing rod spirals upward during discharge, causing the material to swirl, which improves the efficiency of the material passing through the discharge hole and thus improves the material weighing efficiency. Attached Figure Description

[0029] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0030] This application discloses an automatic weighing funnel.
[0031] Reference Figure 1 , Figure 2 and Figure 3 An automatic weighing funnel includes a funnel body 1, a conical portion 2 disposed at the bottom of the funnel body 1, a weighing rod 3, a weighing mechanism 4, a drive mechanism 5 for controlling the lifting and lowering of the weighing rod 3, and a sealing ring 6. One end of the conical portion 2 is fixedly connected to the funnel body 1, and the other end has a discharge hole 21. The weighing rod 3 is used to block the discharge hole 21. The sealing ring 6 is fixedly disposed at the end of the conical portion 2 with the discharge hole 21, and the weighing rod 3 abuts against the sealing ring 6.
[0032] The weighing mechanism 4 includes a support frame 41, a gravity sensor 42 fixedly mounted on the support frame 41, and a weighing ring 43 fixedly mounted on the funnel body 1. The weighing ring 43 is fixedly mounted on the gravity sensor 42.
[0033] The drive mechanism 5 includes a mounting frame 51 and an electric telescopic rod 52 fixedly mounted on the mounting frame 51. The electric telescopic rod 52 is connected to the weighing rod 3. A drive motor 53 is fixedly mounted at the end of the electric telescopic rod 52 away from the mounting frame 51, and the drive shaft of the drive motor 53 is fixedly connected to the weighing rod 3. The electric telescopic rod 52 and the drive motor 53 are used to drive the weighing rod 3 to spiral upward.
[0034] A sealing block 31 for blocking the discharge hole 21 and a conical guide block 32 are fixedly installed at the end of the weighing rod 3 away from the drive motor 53. The guide block 32 is located at the end of the sealing block 31 away from the drive motor 53. A through hole 33 for reducing resistance is opened on the sealing block 31. A guide vane 34 is fixedly installed at the end of the sealing block 31 near the guide block 32. During the spiral ascent of the weighing rod 3, the guide vane 34 agitates the material, causing the material to form a swirling flow and quickly pass through the discharge hole 21, thereby improving the material weighing efficiency.
[0035] The bottom of the sealing ring 6 is integrally formed with a sealing ring 61, which is disposed in the discharge hole 21 and abuts against the conical part 2.
[0036] The implementation principle of an automatic weighing funnel according to an embodiment of this application is as follows: The weighing rod 3 is inserted into the funnel body 1, and the guide block 32 on the weighing rod 3 is inserted into the discharge hole 21 of the conical part 2. The weighing rod 3 abuts against the sealing ring 6, and the guide block 32 abuts against the sealing ring 61. This achieves the sealing of the discharge hole 21, resulting in a good sealing effect, reducing material leakage during the weighing process, and thus improving the accuracy of material weighing. The setting of the sealing ring 6 reduces the wear between the weighing rod 3 and the conical part 2. Material is added to the funnel body 1, and the gravity sensor 42 is used to detect the weight of the material. After the material is weighed, the weighing rod 3 is driven to rise spirally through the electric telescopic rod 52 and the drive motor 53. During the rise of the weighing rod 3, the material is agitated, allowing the material to pass through the discharge hole 21 quickly, thereby improving the efficiency of material weighing.
[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
