Description

Technical Field

[0001] This application relates to the field of soft capsule production technology, and in particular to a dust removal device for soft capsule production. Background Technology

[0002] The production process of soft capsules includes steps such as preparation of the gelatin solution (mixing gelatin, glycerin, etc.), formulation of contents, rotary molding, drying, polishing and cleaning, and packaging. During this process, the adhesion of dust or powder mainly comes from the raw materials of the gelatin solution (such as gelatin debris, opacifier titanium dioxide), polishing agents (talc powder or starch residue), environmental dust (airborne particles), and glue debris generated by mold friction. These contaminants may remain on the capsule due to electrostatic adsorption or surface stickiness, making it difficult to ensure that the product surface is clean and compliant.

[0003] Patent document CN209663744U discloses a dust removal device for fish oil soft capsules. It uses a dust removal fan, dust removal duct and dust removal cylinder to blow air onto the fish oil soft capsules placed on the fish oil soft capsule carrier tray, thereby ensuring that the fish oil soft capsules are not damaged and performing all-round and efficient dust removal, which has certain positive significance. However, the fish oil soft capsules placed on the fish oil soft capsule carrier tray are easily blown off, and it is not possible to blow air from different angles, thus failing to guarantee the dust removal effect and the stability of the dust removal process.

[0023] The present application will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present application, and therefore only show the components relevant to the present application.

[0024] like Figures 1-5 As shown, a dust removal device for soft capsule production includes a dust removal chamber 3. The dust removal chamber 3 is provided with a flipping mechanism that rotates in a vertical horizontal plane. The bottom of the dust removal chamber 3 is provided with a filter screen 6. Below the filter screen 6 is an air chamber 8. The air chamber 8 is provided with an air blowing assembly. The top of the dust removal chamber 3 is provided with a dust suction channel 1.

[0025] This dust removal device includes a dust removal chamber 3, inside which is a flipping mechanism that rotates along a vertical horizontal plane. This flipping mechanism allows the soft capsule to continuously change position within the dust removal chamber 3 and to flip the soft capsule from bottom to top, thus allowing it to be treated for dust removal from multiple angles.

[0026] Below the filter screen 6 is an air chamber 8, and inside the air chamber 8 is an air blowing component. The airflow generated by the air blowing component blows through the filter screen 6 to the dust removal chamber 3, thereby blowing air at different angles onto the constantly rotating soft capsules on the filter screen 6 to blow up the dust and impurities on the surface of the soft capsules, making it easier for subsequent cleaning.

[0027] The top of the dust removal chamber 3 is equipped with a suction channel 1, which can suck away the blown dust and impurities, further improving the dust removal effect.

[0028] Compared to existing technologies where soft capsules placed on a support plate are easily blown off and cannot be blown from multiple angles, this device, through the dust removal chamber 3 and the flipping mechanism, can blow dust off the soft capsules from different angles without worrying about them falling off, thus ensuring the stability and efficiency of the dust removal process.

[0029] In some further embodiments, the flipping mechanism includes a rotating shaft 5 and blades 50. There are multiple blades 50, which are circumferentially spaced on the rotating shaft 5. A bending plate 51 is provided at the end of the blade 5 away from the rotating shaft 5, and the bending direction of the bending plate 51 is consistent with the tangential direction of the blade 50's movement direction.

[0030] The flipping mechanism includes a rotating shaft 5 and multiple blades 50, which are circumferentially spaced on the rotating shaft 5. This multi-blade design allows the soft capsule to be fully flipped up, thereby increasing the contact area with the airflow.

[0031] A bending plate 51 is provided at the end of the blade 50 away from the rotation axis 5. The bending direction of the bending plate 51 is consistent with the tangential direction of the blade 50's movement direction. The design of the bending plate 51 can better bring the soft capsule to a higher position when it flips over, and then drop it as the blade 50 continues to rotate, thereby further increasing the contact area with the airflow. This allows the airflow to more comprehensively blow on the surface of the soft capsule, improving the uniformity of dust removal and ensuring the effectiveness of air blowing dust removal.

[0032] A motor can be installed outside the dust removal chamber 3 to drive the rotating shaft 5 to rotate.

[0033] In some further embodiments, both the blade 50 and the bending plate 51 are provided with mesh 500.

[0034] Both the blade 50 and the bending plate 51 are provided with mesh holes 500. The mesh holes 500 allow airflow to pass more smoothly through the blade 50 and the bending plate 51, enhancing airflow permeability and ensuring all-round blowing and dust removal of the soft capsules. At the same time, the mesh holes 500 also prevent the soft capsules from being adsorbed by the blade 50 and the bending plate 51, avoiding the soft capsules from adhering to the blade 50 and the bending plate 51 due to static electricity or surface stickiness, thus ensuring the normal rotation of the soft capsules and the dust removal effect during the dust removal process.

[0035] In some further embodiments, the filter 6 is tilted.

[0036] Under the action of the flipping mechanism, the soft capsules will be concentrated in one side of the dust removal chamber 3. By setting the filter 6 to be tilted, the aggregation of soft capsules can be avoided.

[0037] In some further embodiments, the dust removal chamber 3 is provided with an inlet 30 and an outlet 31 on its side wall, with the inlet 30 located above the outlet 31.

[0038] The feed inlet 30 is used to introduce soft capsules into the dust removal chamber 3, and the discharge outlet 31 is used to discharge the soft capsules after the dust removal is completed.

[0039] In some further embodiments, the air blowing assembly includes an air inlet pipe 4 and an annular pipe 7; the air inlet pipe 4 is disposed through the side wall of the air chamber 8, and one end of the air inlet pipe 4 located inside the air chamber 8 is connected to the annular pipe 7, and air blowing holes 70 are arranged around the annular pipe 7.

[0040] The air inlet pipe 4 introduces external airflow into the air chamber 8, and then blows the airflow evenly onto the surface of the soft capsule through the air blowing holes 70 on the annular pipe 7. The design of the annular pipe 7 can create a uniform airflow field around the soft capsule, improving the uniformity and effectiveness of dust removal.

[0041] In some further embodiments, the intake pipe 4 is rotatably disposed with the side wall of the air chamber 8, a first pulley 40 is provided on one end of the intake pipe 4 located outside the air chamber 8, a drive motor 42 is provided on the outer side wall of the air chamber 8, a second pulley 41 is provided on the transmission end of the drive motor 42, and the first pulley 40 and the second pulley 41 are connected by a belt 43.

[0042] This rotating configuration allows the air inlet pipe 4 to rotate under the drive of the motor 42, thereby changing the direction of airflow in the annular pipe 7. By adjusting the airflow direction, dust and impurities on the surface of the soft capsule can be cleaned more thoroughly, further improving the dust removal effect. Meanwhile, the belt drive system 43 offers advantages such as simple structure and smooth transmission, ensuring reliable operation of the air blowing assembly.

[0043] The drive motor 42 rotates in a reciprocating motion, with an angle in one direction ranging from 3° to 8°.

[0044] The end of the intake pipe 4 away from the annular pipe 7 can be connected to a flexible hose to meet the reciprocating rotation requirements of the intake pipe 4.

[0045] In some further embodiments, the top of the dust removal chamber 3 is provided with a narrowing section 2, and the diameter of the narrowing section 2 gradually decreases from the direction along the dust removal chamber 3 toward the dust suction channel 1.

[0046] The constriction section 2 is designed to increase the airflow speed as it passes through it, thus enhancing the suction power of the suction channel 1. At the same time, the constriction section 2 also prevents dust and impurities from accumulating at the top of the dust collection chamber 3, improving suction efficiency.

[0047] In some further embodiments, a screen is provided in the dust removal chamber 3, and the screen is located in the narrowing section 2.

[0048] The barrier net can further intercept any soft capsules that are accidentally blown up, preventing them from entering the vacuum duct 1 and causing blockage.

[0049] The entire flipping mechanism can be made of flexible plastic to reduce impact on the soft capsule.

[0050] The rotation speed of the flipping mechanism should not be too high to avoid damaging the soft capsules.

[0051] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this application.
