Description

Technical Field

[0001] The utility model relates to the technical field of filling equipment, in particular to a novel quantitative feeding device. Background Art

[0002] In industries like pharmaceuticals and food, fragile materials (powder particles, sugar, coffee, etc.) often need to be stirred, mixed, stably conveyed, and ultimately precisely metered for the next process for filling. However, existing material handling technologies often face the following technical difficulties when dealing with such fragile materials, resulting in significant material loss, unstable product quality, and poor equipment adaptability:

[0003] 1. Material wear and breakage problems are prominent:

[0004] Damage during conveying: Traditional conveying methods (such as screw conveyors, bucket elevators, pneumatic conveying, and vibrating feeders) are prone to extrusion, shearing, collision, or friction on brittle materials during material movement. The rotating extrusion of spiral blades, the tipping collision of elevator hoppers, the high-speed airflow impact of pneumatic conveying, and the high-frequency impact of vibrating feeders can all easily lead to material breakage and excessive fine powder production. This not only causes material loss but also seriously affects the particle size distribution, appearance, and performance properties (such as solubility, flowability, and activity) of the final product.

[0005] Damage during mixing: When conventional agitators (such as paddle type, ribbon type, and high-speed shear type) mix materials, their rigid blades or high-speed rotating parts will exert a large mechanical force on the materials, which can easily cause particle breakage or structural damage to fragile materials.

[0006] 2. Poor cutting accuracy and controllability:

[0007] Unstable flowability of fragile materials: The fine powder produced after the fragile materials are broken can easily cause the material to form arches, rat holes or stick to the wall, making the flow of materials in the silo or conveying channel extremely unstable and discontinuous, seriously affecting the accuracy and consistency of subsequent quantitative feeding.

[0008] Existing dosing devices lack adaptability: Common volumetric (e.g., rotary valves, screw feeders) or gravity (e.g., vibrating feeders, belt scales) dosing devices struggle to precisely control discharge volume when faced with changes in fluidity, density, or increased adhesion caused by breakage of fragile materials, resulting in significant fluctuations in accuracy. Adjusting discharge volume often requires replacing components (e.g., screws with different pitches, valves of different sizes) or performing complex mechanical adjustments, resulting in slow response and limited flexibility.

[0026] In order to make the purpose, technical solutions and advantages of the present invention clearer, Figure 1-Figure 2 The utility model is further described in detail with reference to the accompanying drawings.

[0031] The rotation driving device 6 of this embodiment is a common driving form commonly used to drive the rotating shaft 2 to rotate, such as a motor combined with a reducer, and is not further limited or elaborated in this embodiment.

[0032] This embodiment does not limit the number of stirring blocks 3 .

[0033] In this embodiment, the number of the discharge holes 11 corresponds to the number of the stirring blocks 3 .

[0034] Furthermore, the two sides of the bottom of the storage box 1 are inclined, and the inclination direction is inclined toward the discharge hole 11.

A gap is provided between the arc-shaped surface 31 and the arc-shaped recess 12 to prevent excessive wear of the material.

[0035] This embodiment optimizes the mixing and conveying form of the material. The mixing block mixes the material and performs a circular motion to drive the material in the storage box to be discharged to the discharge hole. The mixing block pushes the material by performing a circular motion, which has the advantage of less wear on the material.

[0036] The dosing module 4 includes a cup support plate 41, a plurality of cups 42, and a lifting drive 43. The cup support plate 41 is arranged to be raised and lowered at the bottom of the storage box 1. Specifically, four guide shafts 13 are vertically mounted at the bottom of the storage box 1, and the four guide shafts 13 are arranged diagonally. Linear bearings are fixedly mounted at the four diagonal corners of the cup support plate 41 and are slidably connected to the guide shafts 13.

[0037] A plurality of material cups 42 are arranged on the material cup support plate 41 at intervals along the length direction of the material storage box 1. In this embodiment, the number of material cups 42 corresponds to the number of discharge holes 11, and they are opposite to each other up and down.

[0038] Specifically, the cup support plate 41 is provided with a through-hole 411 for accommodating the cup 42. The lower half of the cup 42 is inserted into the through-hole 411, with the bottom of the cup 42 flush with the bottom of the cup support plate 41. The outer periphery of the bottom of the cup 42 is secured against the cup support plate 41 by screws. Simultaneously, the top of the cup 42 is inserted into the discharge hole 11, with the outer periphery of the cup 42 sliding along the inner wall of the discharge hole 11.

The number of the material blocking portions 52 of the embodiment is consistent with the number of the measuring cups, and each of the material blocking portions 52 is opposite to the measuring cup in a one-to-one manner.

[0043] Compared with the prior art, the material cup is reversibly arranged in the discharge hole in the embodiment, which greatly reduces the conveying distance of the material, simplifies the structure of the equipment, and reduces the production cost and maintenance cost of the equipment. At the same time, through the cooperation of the arc-shaped recess and the stirring block with the arc-shaped bottom surface, the stirring block realizes stirring and feeding, and at the same time, the opening part of the movable opening and closing discharge hole is prevented from entering the quantitative cavity, thereby further simplifying the structure of the equipment.

[0044] The bottom of the material storage box body 1 is provided with a turnover driving device 8 for driving the material blocking plate 5 to perform a turnover action, and the bottom of the material storage box body 1 is provided with a support arm 14.

[0046] Further, the bottom of the plug-in hole 411 is provided with a shielding cover 9, and the top of the shielding cover 9 is fixedly connected with the bottom of the material cup support plate 41.

[0047] In the initial state, the stirring block 3 is set vertically with its bottom end facing upwards.

[0048] S1, the rotary drive device 6 drives the rotating shaft 2 to rotate so that the stirring block 3 stirs the material. The stirring block 3 rotates one circle to push the material in the storage box 1 into the discharge hole 11 and into the quantitative chamber 7. At the same time, the bottom end of the stirring block 3 is relative to the discharge hole 11 so that the material stops falling into the measuring cup;

[0049] S2, the turning drive device 8 drives the material blocking plate 5 to turn downward so that the material blocking portion 52 is away from the bottom of the material cup support plate 41, and the material in the quantitative cavity 7 is discharged from the bottom end of the insertion through hole 411 for discharge;

[0050] S3, the turning drive device 8 drives the material blocking plate 5 to turn upward, so that the material blocking portion 52 abuts against the top of the material cup support plate 41 to close the quantitative cavity 7 and wait for the next material discharge operation.

[0051] Compared with the existing unloading device, this device has the advantages of less dust and low material wear rate, and can be used for unloading fragile items.
