[0002] Hollow capsules are one of the most commonly used pharmaceutical excipients. With the improvement of people's living standards and medical levels, capsules have begun to be used in large quantities in the food and cosmetics industries in addition to medicines.

[0055] A third electric push rod is fixedly mounted on both ends of the inner wall of the hollow tube;

[0056] An extrusion plate is fixedly mounted on the output end of the third electric push rod via a piston rod.

[0057] A fully automatic production method for plant enteric-coated hollow capsules comprises the following specific steps:

[0058] Step 1: Select a hollow mold column or a solid mold column according to the size of the hollow capsule to be produced. If a solid mold column is selected, remove the hollow mold column;

[0059] Step 2: The servo motor rotates the screw. When the screw rotates, it drives the slider to move up and down. When the slider moves up and down, it drives the mold mechanism to move up and down until the mold mechanism is located above the oil storage tank.

[0060] Step 3: When the mold mechanism is located above the oil storage tank, the fixed rod drives the mold mechanism to move toward the oil storage tank through the first electric push rod until the mold mechanism is directly above the oil storage tank. Afterwards, the mold mechanism is lowered by the lifting assembly until the hollow mold column or the solid mold column is immersed in the oil on the oil storage tank, thereby achieving oiling of the hollow mold column or the solid mold column;

[0061] Step 4: After the hollow mold column or the solid mold column is oiled, the mold mechanism is positioned directly above the glue liquid storage tank by means of the position adjustment mechanism. When the mold mechanism is directly above the glue liquid storage tank, the mold mechanism is lowered by means of the lifting assembly until the hollow mold column or the solid mold column is immersed in the glue liquid on the glue liquid storage tank, thereby achieving the dipping of the hollow mold column or the solid mold column in glue;

[0062] Step 5: After the hollow mold column or the solid mold column is dipped in glue, the mold mechanism is positioned directly above the thickness adjustment mechanism through the position adjustment mechanism. When the mold mechanism is directly above the thickness adjustment mechanism, the mold mechanism is lowered by the lifting assembly until the hollow mold column or the solid mold column is inserted into the through hole. At this time, the scraper is moved toward the hollow mold column or the solid mold column by the second electric push rod until the distance between the scraper and the hollow mold column or the solid mold column reaches a desired value. At this time, the rotating plate is driven by the motor to rotate the scraper around the hollow mold column or the solid mold column, thereby adjusting the thickness of the glue on the hollow mold column or the solid mold column, wherein the scraped glue flows into the collection box;

[0063] Step 6: After adjusting the thickness of the glue on the hollow mold column or the solid mold column, the mold mechanism is positioned in the inner cavity of the U-shaped plate through the position adjustment mechanism. At this time, the glue on the hollow mold column or the solid mold column is heated by the heating tube, thereby drying the glue on the hollow mold column or the solid mold column;

[0064] Step 7: After the glue on the hollow mold column or the solid mold column is dried, the mold mechanism is positioned directly above the demoulding mechanism through the position adjustment mechanism. At this time, the mold mechanism is lowered by the lifting assembly until the hollow mold column or the solid mold column is inserted into the hollow tube. After that, the extrusion plate is squeezed on the hollow mold column or the solid mold column by the third electric push rod. After squeezing, the mold mechanism is raised by the lifting assembly to realize demoulding of the hollow capsule, and the removed hollow capsule will flow down through the discharge hole;

[0065] Step 8: When one set of mold mechanisms is demoulding, the other set of mold mechanisms will carry out the remaining processes, thereby enabling the two sets of mold mechanisms to work alternately.

[0066] Compared with existing technologies:

[0067] 1. By arranging the oil storage tank, glue storage tank, thickness adjustment mechanism, drying assembly and demoulding mechanism from top to bottom on the side plate, and then providing a position adjustment mechanism to drive the mold mechanism to move in multiple directions, the volume of the equipment is greatly reduced, thereby reducing the occupied space;

[0068] 2. By setting up two sets of position adjustment mechanisms to drive one set of mold mechanisms to move in multiple directions, it is possible to make the two sets of mold mechanisms work alternately, thereby greatly improving the production efficiency of hollow capsules;

[0069] 3. The thickness of the glue on the mold mechanism is adjusted by setting a thickness adjustment mechanism, which has the effect of keeping the thickness of the hollow capsule wall consistent, thereby improving the quality of the hollow capsule;

[0070] 4. By arranging a hollow mold column and a solid mold column at the bottom end of the first square plate, and then placing the solid mold column in the hollow mold column, it is possible to adjust the size of the hollow capsules to be produced, thereby enabling the production of hollow capsules of various sizes;

[0071] 5. By providing a demoulding mechanism to remove the hollow capsules on the mold mechanism, it is possible to remove several hollow capsules on the mold mechanism at the same time, thereby shortening the demoulding time and further improving the production efficiency of the hollow capsules.

[0105] A fully automatic production method for plant enteric-coated hollow capsules comprises the following specific steps:

[0106] Step 1: Select a hollow mold column 34 or a solid mold column 35 according to the size of the hollow capsule to be produced. If the solid mold column 35 is selected, remove the hollow mold column 34;

[0107] Step 2: The servo motor 24 rotates the screw 21. When the screw 21 rotates, it drives the slider 22 to move up and down. When the slider 22 moves up and down, it drives the mold mechanism 30 to move up and down until the mold mechanism 30 is located above the oil storage tank 40.

[0108] Step 3: When the mold mechanism 30 is located above the oil storage tank 40, the first electric push rod 25 causes the fixed rod 26 to drive the mold mechanism 30 to move toward the oil storage tank 40 until the mold mechanism 30 is directly above the oil storage tank 40.

[0109] Step 4: After the hollow mold column 34 or the solid mold column 35 is oiled, the mold mechanism 30 is positioned directly above the glue storage tank 50 by means of the position adjustment mechanism 20. When the mold mechanism 30 is directly above the glue storage tank 50, the mold mechanism 30 is lowered by means of the lifting assembly until the hollow mold column 34 or the solid mold column 35 is immersed in the glue in the glue storage tank 50, thereby achieving the dipping of the hollow mold column 34 or the solid mold column 35 in glue.

[0110] Step 5: After the hollow mold column 34 or the solid mold column 35 is dipped in glue, the mold mechanism 30 is positioned directly above the thickness adjustment mechanism 60 by the position adjustment mechanism 20. When the mold mechanism 30 is directly above the thickness adjustment mechanism 60, the mold mechanism 30 is lowered by the lifting assembly until the hollow mold column 34 or the solid mold column 35 is inserted into the through hole 62. At this time, the scraper 638 is moved toward the hollow mold column 34 or the solid mold column 35 by the second electric push rod 637 until the distance between the scraper 638 and the hollow mold column 34 or the solid mold column 35 reaches a desired value. At this time, the rotating plate 634 is driven by the motor 633 to rotate the scraper 638 around the hollow mold column 34 or the solid mold column 35, thereby adjusting the thickness of the glue on the hollow mold column 34 or the solid mold column 35. The scraped glue will flow into the collection box 631.

[0111] Step 6: After adjusting the thickness of the glue on the hollow mold column 34 or the solid mold column 35, the mold mechanism 30 is positioned within the inner cavity of the U-shaped plate 71 by the position adjustment mechanism 20. At this time, the glue on the hollow mold column 34 or the solid mold column 35 is heated by the heating tube 72, thereby drying the glue on the hollow mold column 34 or the solid mold column 35.

[0112] Step 7: After the glue on the hollow mold column 34 or the solid mold column 35 is dried, the mold mechanism 30 is positioned directly above the demolding mechanism 80 by the position adjustment mechanism 20. At this time, the mold mechanism 30 is lowered by the lifting assembly until the hollow mold column 34 or the solid mold column 35 is inserted into the hollow tube 831. Thereafter, the extrusion plate 833 is squeezed against the hollow mold column 34 or the solid mold column 35 by the third electric push rod 832. After squeezing, the mold mechanism 30 is raised by the lifting assembly to demold the hollow capsule. The removed hollow capsule flows down through the discharge hole 82.

[0113] Step 8: When one set of mold mechanisms 30 is performing demoulding, the other set of mold mechanisms 30 will perform the remaining processes, thereby enabling the two sets of mold mechanisms 30 to work alternately.

6. A fully automatic production method for plant enteric-coated hollow capsules, characterized in that: The specific steps are as follows: Step 1: Select a hollow mold column (34) or a solid mold column (35) according to the size of the hollow capsule to be produced. If the solid mold column (35) is selected, remove the hollow mold column (34); Step 2: The screw (21) is rotated by the servo motor (24). When the screw (21) rotates, the slider (22) is driven to move up and down. When the slider (22) moves up and down, the mold mechanism (30) is driven to move up and down until the mold mechanism (30) is located above the oil storage tank (40). Step 3: When the mold mechanism (30) is located above the oil storage tank (40), the fixed rod (26) drives the mold mechanism (30) to move toward the oil storage tank (40) through the first electric push rod (25) until the mold mechanism (30) is located directly above the oil storage tank (40). Afterwards, the mold mechanism (30) is lowered through the lifting assembly until the hollow mold column (34) or the solid mold column (35) is immersed in the oil on the oil storage tank (40), thereby achieving oiling of the hollow mold column (34) or the solid mold column (35); Step 4: After the hollow mold column (34) or the solid mold column (35) is oiled, the mold mechanism (30) is positioned directly above the glue storage tank (50) by the position adjustment mechanism (20). When the mold mechanism (30) is positioned directly above the glue storage tank (50), the mold mechanism (30) is lowered by the lifting assembly until the hollow mold column (34) or the solid mold column (35) is immersed in the glue on the glue storage tank (50), thereby achieving the dipping of the hollow mold column (34) or the solid mold column (35); Step 5: After the hollow mold column (34) or the solid mold column (35) is dipped in glue, the mold mechanism (30) is positioned directly above the thickness adjustment mechanism (60) through the position adjustment mechanism (20). When the mold mechanism (30) is directly above the thickness adjustment mechanism (60), the mold mechanism (30) is lowered through the lifting assembly until the hollow mold column (34) or the solid mold column (35) is inserted into the through hole (62). At this time, the scraper (638) is moved toward the hollow mold column through the second electric push rod (637). The mold column (34) or the solid mold column (35) is moved until the distance between the scraper (638) and the hollow mold column (34) or the solid mold column (35) reaches a desired value. At this time, the motor (633) causes the rotating plate (634) to drive the scraper (638) to rotate around the hollow mold column (34) or the solid mold column (35), thereby adjusting the thickness of the glue on the hollow mold column (34) or the solid mold column (35). The scraped glue flows into the collection box (631); Step 6: After adjusting the thickness of the glue on the hollow mold column (34) or the solid mold column (35), the mold mechanism (30) is positioned in the inner cavity of the U-shaped plate (71) through the position adjustment mechanism (20). At this time, the glue on the hollow mold column (34) or the solid mold column (35) is heated through the heating tube (72), thereby drying the glue on the hollow mold column (34) or the solid mold column (35); Step 7: After the glue on the hollow mold column (34) or the solid mold column (35) is dried, the mold mechanism (30) is positioned directly above the demoulding mechanism (80) by the position adjustment mechanism (20). At this time, the mold mechanism (30) is lowered by the lifting assembly until the hollow mold column (34) or the solid mold column (35) is inserted into the hollow tube (831). After that, the extrusion plate (833) is squeezed on the hollow mold column (34) or the solid mold column (35) by the third electric push rod (832). After squeezing, the mold mechanism (30) is raised by the lifting assembly, thereby realizing demoulding of the hollow capsule, and the removed hollow capsule will flow down through the discharge hole (82); Step 8: When one set of mold mechanisms (30) is performing demoulding, the other set of mold mechanisms (30) will perform the remaining processes, thereby enabling the two sets of mold mechanisms (30) to work alternately.
