Description

Technical Field

[0001] The invention relates to the technical field of soft capsule production, and in particular to integrated equipment for producing traditional Chinese medicine soft capsules. Background Art

[0002] Chinese medicine soft capsule is a dosage form that is quantitatively encapsulated in a soft capsule after extraction and concentration of Chinese medicine. It is convenient to carry and does not come into contact with air to keep the medicinal properties stable. Chinese medicine soft capsule is usually produced by a pill press, that is, a pair of capsule outer membranes are transported between a pair of pill press rollers, and the injection machine quantitatively injects the Chinese medicine liquid into the pair of capsule outer membranes, and then the pair of capsule outer membranes are extruded and formed using the molding grooves on the surface of the pill press rollers, so that the Chinese medicine liquid is wrapped inside the capsule outer membrane to form a Chinese medicine soft capsule. When the Chinese medicine soft capsule production equipment is in use, because the capsule outer membrane is sticky and easy to break, after the pill press roller squeezes the capsule outer membrane, the surface of the pill press roller and the inside of the molding groove are prone to residual sticky residues of the capsule outer membrane or drug leakage. Over time, the residues accumulate more and more, which will affect the use of the pill press roller and cause the molding quality of the capsule to decline.

[0003] In order to be able to clean the sticky residues of the capsule outer membrane or leaked drugs remaining on the surface of the pill pressing roller and inside the forming groove in time, there are many existing methods. For example, the Chinese invention patent with publication number "CN202410633716.9" adopts a detection rod to detect whether there are residual soft capsules in the groove. If so, the rubber clip will clamp the residual soft capsules out of the groove to prevent the soft capsules from sticking in the groove and affecting subsequent operations; there is also a Chinese invention patent with publication number "CN202311703929.6" that uses clean water to rinse the pill pressing roller and the forming groove, and then uses elastic wire to scrape and clean the residues on the pill pressing roller and in the forming groove. When using rubber clamps to clamp the residues, it is necessary to check the forming grooves one by one and then clamp them, which makes the efficiency of removing the residues very low; when using clean water flushing combined with elastic wire scraping, it is necessary to stop the soft capsule production before cleaning. After cleaning, clean water remains on the pill pressing roller and in the forming groove, and drying operation has to be carried out, which takes a long time and will reduce the production efficiency of the soft capsule. Therefore, the existing cleaning methods either have low cleaning efficiency or take a long time, which will affect the production efficiency of the soft capsule. Summary of the invention

[0004] The purpose of the present invention is to provide an integrated equipment for producing Chinese medicine soft capsules, so as to solve the problem that when cleaning the residues on the pill pressing roller and in the forming groove, the cleaning efficiency is low and the time is long, resulting in reduced production efficiency of the soft capsules.

[0005] In order to solve the above problems, the technical solutions provided are as follows:

[0006] An integrated device for producing Chinese medicine soft capsules comprises a pill pressing roller and a plurality of forming grooves arranged on the pill pressing roller, a rotating cleaning mechanism is arranged at the bottom end of the pill pressing roller, an arc-shaped suction head facing the pill pressing roller is arranged at the bottom end of the pill pressing roller, the length of the arc-shaped suction head is greater than the length of the pill pressing roller, the arc-shaped suction head is located above and behind the rotating cleaning mechanism in the rotating direction, and the side of the arc-shaped suction head away from the pill pressing roller is connected to an adsorption mechanism capable of generating negative pressure through a pipeline.

[0007] The basic principle of the above technical solution is that the Chinese medicine soft capsules are formed in the molding groove of the pill pressing roller, and the pill pressing roller continues to rotate. The rotating cleaning mechanism will clean out the Chinese medicine soft capsules formed in the molding groove. When there are Chinese medicine soft capsules remaining on the pill pressing roller and in the molding groove, leaked drugs or adhesion of capsule outer membranes, the pill pressing roller rotates through the arc-shaped suction head. At this time, the adsorption mechanism is started. The arc-shaped suction head can generate suction under the action of the adsorption mechanism to suck away all the residual materials on the pill pressing roller and in the molding groove. The pill pressing roller continues to rotate, and the production of Chinese medicine soft capsules can continue.

[0008] The beneficial effect of the above technical solution is that compared with the existing method of clamping residues by rubber clips or rinsing with clean water and scraping the residues on the pill pressing roller and in the forming groove with elastic wire, the present technical solution directly adopts an arc-shaped suction head that can generate suction to suck away all the residues at one time, and the pill pressing roller does not need to stop working, and will not affect the production efficiency of Chinese medicine soft capsules. After each time the pill pressing roller presses and forms a soft capsule in the forming groove, it will rotate through the arc-shaped suction head, and the arc-shaped suction head will clean the residues on the pill pressing roller and in the forming groove. There is no accumulation of residues, which improves the cleaning efficiency and does not waste the production time of the pill pressing roller.

[0009] Furthermore, the adsorption mechanism includes an adsorption box, in which a storage box and a motor fan are arranged, an air outlet is arranged on one side of the storage box, and an inlet is arranged on the other side, the air inlet of the motor fan is inserted into the air outlet of the storage box, a filter plate is arranged at the connection between the motor fan and the storage box, and the inlet of the storage box is connected to the arc-shaped suction head through a pipe. When the electric fan is turned on to start suction, the inside of the storage box is in a negative pressure state, and the arc-shaped suction head connected to the storage box can generate suction to absorb the residue on the pill pressing roller and in the forming groove, and the residue remains in the storage box under the barrier of the filter plate, while the sucked air flows out of the storage box through the air outlet.

[0010] Furthermore, one end of the filter plate passes through the top of the storage box and extends out of the adsorption box, and a lifting handle is provided at the end of the filter plate extending out of the adsorption box. The lifting handle can be used to conveniently pull the filter plate out of the storage box for replacement.

[0011] Furthermore, a strip opening is provided at the top of the storage box, the strip opening of the filter plate is inserted into the storage box and blocks the air outlet of the storage box, and a sealing ring is provided at the strip opening. When the filter plate is inserted into the storage box, the sealing ring can ensure that the air sucked out by the fan will hardly flow out from the strip opening.

[0012] Furthermore, the adsorption mechanism includes a venturi tube and a fan. The venturi tube is arranged vertically and is located on one side of the pill pressing roller. The top of the venturi tube is fixedly connected to the air outlet of the fan. The throat of the venturi tube is connected to the arc-shaped suction head through a pipe. A storage box is placed at the bottom of the venturi tube. When the fan is started to blow air from top to bottom into the venturi tube, the throat of the venturi tube will be in a negative pressure state, so that the arc-shaped suction head generates suction to adsorb the residue on the pill pressing roller and in the forming groove. The residue will be sucked into the venturi tube. Under the action of wind force, the residue will be blown to the bottom of the venturi tube and fall into the storage box for collection.

[0013] Furthermore, the arc-shaped suction head is 5-20 mm away from the pill pressing roller. The arc-shaped suction head is 5-20 mm away from the pill pressing roller, which will not affect the rotation of the pill pressing roller, and can also make the suction force generated by the arc-shaped suction head act on the pill roller and the forming groove.
