Description

Technical Field

[0001] The utility model relates to the technical field of soft capsule production, in particular to a pill pressing machine for soft capsule production. Background Technique

[0002] Soft capsules, also known as gelatin capsules, are a type of packaging for capsules, commonly found in pharmaceuticals or health foods. They are a type of capsule made by sealing liquid drugs or liquid fruit drugs in a soft capsule material after treatment. Specifically, substances such as vitamin D, vitamin K, compound houttuynia, and eicosapentaenoic acid ethyl ester can be contained in the capsule for people to take, so they are widely used.

[0003] The material of the soft capsule is made of capsule gelatin, glycerin, or other suitable pharmaceutical excipients alone or in combination, and is made through a pill pressing system. The pill pressing system for capsule preparation consists of a main machine, a chiller, a shaping and drying rotary cage, a heat preservation glue injection barrel, and a feeding barrel. The main machine includes a machine body, a feeder, an oil roller, a pill discharging device, a spreading box, etc. The gel liquid is evenly applied on the rotating rubber wheel to form a rubber sheet, which is sent to the rotating rubber guide wheel, and passes through a mold, a brush, and a pill discharging brush, and finally sent into the rubber sheet recycling machine. The wedge-shaped spray body is lowered to press on the rubber sheet by its own gravity to complete the filling of the material, and then the pill pressing is completed through two relatively rotating molds.

[0004] Specifically, during the pressing process of the soft capsule pill pressing machine, since the glue liquid is in a molten state and needs to solidify into a shell, its forming speed is relatively slow. As a result, the capsules are easily adhered to the mold. Although there is a brush to brush the capsules that have completed pill pressing for discharging, since most of the capsules are on the mold, when the capsules have a large viscosity, the brush cannot brush the capsules to demold, which greatly affects the preparation efficiency of the capsules. For this reason, we have proposed a pill pressing machine for soft capsule production. Content of the Utility Model

[0005] The utility model provides a pill pressing machine for soft capsule production, which solves the problems raised in the above background technique.

[0006] To achieve the above object, the utility model is realized by the following technical solutions: A pill - pressing machine for soft capsule production, comprising two rotary molds installed on the main body of the pill - pressing machine. The pills are pressed by the relative rotation of the two rotary molds. A plurality of capsule pill - pressing grooves for pressing pills are arranged on the outer side of the rotary mold. One side of the middle of the capsule pill - pressing groove close to the inside of the rotary mold is in through - communication with the inside of the capsule pill - pressing groove. And a capsule baffle plate capable of pushing the capsule to discharge is movably installed at the communication part between the inside of the rotary mold and the capsule pill - pressing groove. One side of the capsule baffle plate close to the inside of the rotary mold is fixedly connected with a discharge - guiding column. A pushing guide roller fixed to the main body of the pill - pressing machine is connected inside the rotary mold. The discharge - guiding column can contact the pushing guide roller to automatically push the capsule to discharge.

[0007] Optionally, the capsule baffle plate fits with the inner wall of the capsule pill - pressing groove, and the inner end of the discharge - guiding column extending into the inside of the rotary mold is semicircular. There is a gap between the side walls of the two adjacent pushing guide rollers and the inner wall of the rotary mold.

[0008] Optionally, the gap can completely accommodate the discharge - guiding column, and at this time, the capsule baffle plate fits with the inner wall of the capsule pill - pressing groove.

[0009] Optionally, a plurality of fixed connecting rods are fixedly connected to the outer side of the discharge - guiding column, and a circular transmission ring plate is fixedly connected to the outer ends of the fixed connecting rods.

[0010] Optionally, a return spring is fixedly connected to the side of the transmission ring plate close to the capsule baffle plate, and one end of the return spring is fixed to the inner wall of the rotary mold.

[0011] Optionally, the capsule pill - pressing grooves are evenly distributed on the rotary mold.

[0012] The utility model has the following beneficial effects:

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1 to 5, A pill - pressing machine for soft capsule production, including two rotary molds 1 installed on the main body of the pill - pressing machine. The main body of the pill - pressing machine is the same as the prior art and will not be elaborated in this application. By using the rotating mechanism of the main body of the pill - pressing machine to connect with the rotary mold 1, its actions are then completed to assist in subsequent preparation. Pills are pressed through the relative rotation of the two rotary molds 1. Through the relative rotation of the two rotary molds 1, pills are further pressed. This is the prior art and no improvement is made here, so no detailed elaboration is provided. A plurality of capsule - pressing grooves 2 for pressing pills are provided on the outer side of the rotary mold 1. When the rotary mold 1 rotates, the capsule - pressing grooves 2 on the two rotary molds 1 are closed for pill - pressing. The middle of the capsule - pressing groove 2 near the inner side of the rotary mold 1 is in through - communication with the inside of the capsule - pressing groove 2. And a capsule baffle 4 that can push the capsule to discharge is movably installed at the connection between the inside of the rotary mold 1 and the capsule - pressing groove 2. Through the push of the capsule baffle 4, the soft capsules that have completed pill - pressing in the capsule - pressing groove 2 can be smoothly pushed out of the capsule - pressing groove 2 by the capsule baffle 4, enabling the soft capsules to be discharged smoothly and preventing the soft capsules from adhering to the inner wall of the capsule - pressing groove 2. One side of the capsule baffle 4 close to the inside of the rotary mold 1 is fixedly connected to a discharge - guiding column 5. Driven by the discharge - guiding column 5, the capsule baffle 4 can move smoothly, enabling the capsule baffle 4 to push the material and return to its position. A push - guiding roller 3 fixed to the main body of the pill - pressing machine is connected inside the rotary mold 1. Then, when the rotary mold 1 rotates, the push - guiding roller 3 remains stationary, so that relative rotation can occur between the rotary mold 1 and the push - guiding roller 3. The discharge - guiding column 5 can contact the push - guiding roller 3 to automatically push the capsule to discharge.

[0023] Please refer to Figures 1 to 5 , The capsule baffle 4 fits with the inner wall of the capsule - pressing groove 2, enabling the soft capsule to be completely formed by pill - pressing. And the inner end of the discharge - guiding column 5 extending into the rotary mold 1 is semi - circular. Then, when the discharge - guiding column 5 rotates and moves, the discharge - guiding column 5 can smoothly move along the outer side of the push - guiding roller 3. There is a gap between the side walls of the two push - guiding rollers 3 close to each other and the inner wall of the rotary mold 1.

[0024] Please refer to Figures 1 to 5 , The gap can completely accommodate the discharge - guiding column 5. At this time, the capsule baffle 4 fits with the inner wall of the capsule - pressing groove 2, enabling the rotation of the rotary mold 1 to smoothly press pills in the capsule - pressing groove 2.

[0025] Please refer to Figures 1 to 5, a plurality of fixed connecting rods 6 are fixedly connected to the outer side of the discharge derivation column 5. Driven by the fixed connecting rods 6, the discharge derivation column 5 can move smoothly. The outer end of the fixed connecting rod 6 is fixedly connected with a transmission ring plate 7 in the shape of a ring. Driven by the transmission ring plate 7, the fixed connecting rod 6 can smoothly drive the discharge derivation column 5 to move.

[0026] Please refer to Figures 1 to 5 , one end of a return spring 8 is fixedly connected to the side of the transmission ring plate 7 close to the capsule baffle 4, and the other end of the return spring 8 is fixed to the inner side wall of the rotary die 1. Under the elastic force of the return spring 8, after the discharge derivation column 5 pushes out the material, as the rotary die 1 rotates, when the discharge derivation column 5 moves to the gap again, the discharge derivation column 5 can smoothly drive the capsule baffle 4 to return to its position, so as to facilitate the smooth pill pressing next time, thus ensuring the continuity of pill pressing.

[0027] The capsule pill pressing grooves 2 are evenly distributed on the rotary die 1 to ensure the preparation of capsules.

[0028] In summary, when the soft capsule pill press for soft capsule production is in use, when the two capsule pill pressing grooves 2 rotate relatively, at this time, the capsule film is pressed between the rotary dies 1, and before pressing, the material is injected. Then, under the relative rotation of the rotary dies 1, pill pressing is carried out in the capsule pill pressing grooves 2. After pill pressing, the rotary dies 1 continue to rotate, driving the soft capsules in the capsule pill pressing grooves 2 to rotate and discharge. The capsule baffle 4 is driven by the rotary die 1, and its discharge derivation column 5 contacts the pushing guide roller 3. Then, under the relative action of the pushing guide roller 3, the discharge derivation column 5 is gradually pushed towards the capsule pill pressing groove 2, and then the capsule baffle 4 can move towards the capsule pill pressing groove 2, thereby pushing out the soft capsules in the capsule pill pressing groove 2 to ensure the smooth discharge of the capsules. Under the action of the elastic force of the return spring 8, when the discharge derivation column 5 rotates one week and the capsule pill pressing groove 2 presses pills again, the capsule baffle 4 can smoothly return to its position to facilitate the next pill pressing.
