Description

Technical Field

[0001] This utility model relates to the field of powder screw metering and packaging technology, specifically a leak-proof screw mesh for powder metering and packaging. Background Technology

[0002] The screw feeder is a new generation product that integrates stable flow conveying, weighing and metering, and quantitative control of powder materials. It is suitable for continuous metering and batching of powder materials in various production environments. It adopts a number of advanced technologies, is reliable in operation, and has high control accuracy. It is especially suitable for continuous metering and batching of powder materials in the food production industry.

[0003] Authorization announcement number CN219971231U discloses a screw conveyor device for powder production. This device mainly utilizes the combined action of a conveying motor and screw blades. The conveying motor is fixedly mounted on one side of a mounting plate, and the screw blades are fixedly connected to the outside of a rotating rod. The conveying motor drives the rotating rod to rotate, which in turn drives the screw blades to rotate. The rotation of the screw blades enables conveying, effectively preventing powder blockage and improving conveying efficiency. However, in actual use, the device still has the following drawbacks:

[0004] The aforementioned patent mainly uses the combined action of the conveying motor and the spiral blades to convey materials and avoid blockage. However, when the powder has good flowability, the powder material is easy to slip out from the conveying blades of the screw, resulting in the powder falling vertically and causing leakage. This affects the accuracy of the screw feeding and metering, and reduces the stability of the screw feeding of highly flowable materials. Utility Model Content

[0007] Preferably, the outer side of the tube body has multiple sets of grooves, which facilitates the reduction of the tube body's weight by utilizing the grooves.

[0008] Preferably, the interior of the mounting tube is a mounting hole, and the inner side of the mounting hole is provided with a hollow screw that is fixedly engaged with the leak-proof mesh.

[0009] Preferably, the outer diameter of the leak-proof mesh is 10-100mm, and the number of blades is 2-8, which facilitates the installation of a specified number of blades according to the needs of the screw to prevent leakage of powder materials during feeding.

[0010] Preferably, a specified number of leak-proof mesh sheets are installed on the outside of the mounting tube, and the mounting tube and leak-proof mesh sheets are set at the bottom of the rod body to improve the stability and leak-proof effect of screw feeding.

[0011] Preferably, the rod and spiral blades are disposed on the inner side of the tube, which facilitates the metering of powder inside the tube by rotating the rod and spiral blades.

[0012] The powder metering and packaging leak-proof screw mesh proposed in this utility model has at least the following beneficial effects:

[0013] By installing an installation tube and a leak-proof mesh at the bottom of the rod, and utilizing the leak-proof mesh with an outer diameter of 10-100mm and the number of blades set to 2-8 according to the screw requirements, with a blade overlap dimension of ±15°, the leak-proof function of the screw feeding process is achieved.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0020] Please see Figure 1-4The present invention provides an embodiment of a powder metering and packaging leak-proof screw mesh, comprising a tube body 1 and a rod body 2. The rod body 2 extends into the interior of the tube body 1. Multiple sets of grooves are provided on the outer side of the tube body 1 to facilitate the reduction of the weight of the tube body by utilizing the grooves. Spiral blades 3 are provided on the outer side of the rod body 2. An installation tube 5 is connected to the bottom of the rod body 2. A leak-proof mesh 4 is provided on the outer side of the installation tube 5. The interior of the installation tube 5 is an installation hole, and a hollow screw is provided on the inner side of the installation hole to fix and cooperate with the leak-proof mesh 4.

[0021] A specified number of leak-proof mesh sheets 4 are installed on the outside of the mounting pipe 5. The mounting pipe 5 and the leak-proof mesh sheets 4 are set at the bottom of the rod body 2 to improve the stability of screw feeding and the leak-proof effect.

[0022] The rod 2 and the spiral blade 3 are arranged inside the tube 1, which facilitates the feeding and metering of powder inside the tube 1 by rotating the rod 2 and the spiral blade 3.

[0023] Example 1, as Figure 1-4 As shown, the outer diameter of the leak-proof mesh 4 is 10-100mm, and the number of blades is 2-8, with a blade overlap of ±15°. By setting a specified number of leak-proof meshes 4 on the outside of the mounting pipe 5, the bottom of the rod 2 is blocked from leakage. In this way, in conjunction with the rotation of the rod 2 and the spiral blades 3, the blocked and leak-proof powder material is re-conveyed upwards and fed, improving the accuracy of material metering.

[0024] Working principle: This powder metering and packaging leak-proof screw mesh;

[0025] By setting a rod 2 and a spiral blade 3 inside the tube body 1, the screw can feed powder using the combined action of the rod 2 and the spiral blade 3. The structure of the mounting tube 5 and the leak-proof mesh 4 allows for the installation of a leak-proof screw mesh at the bottom of the rod 2 as needed. The synchronous rotation of the mesh can block and prevent leakage of free-flowing powder, and allow the powder to be conveyed upwards again, improving the accuracy of screw feeding and metering. This solves the defect of powder leakage and inaccurate metering caused by screw feeding.
