Description

Technical Field

[0001] The utility model relates to the technical field of capsule forming machines, in particular to a soft capsule pill forming machine. Background Art

[0002] The soft capsule pills formed by the soft capsule machine are very soft and have too high water content because the rubber covering the medicine is very thin and contains a lot of water. In addition, the rubber surface needs to be lubricated with lubricating liquid during the production process. Therefore, the capsule pills produced are very soft and have too high water content. They cannot be directly packaged and stored, which requires immediate shaping, drying, and dehydration. Shaping and drying need to be carried out at the same time, that is, each new soft capsule must be dried and dehydrated during the continuous tumbling process. Usually, this process is carried out in a traditional rolling cage dryer. The main body of the traditional dryer is a rolling cage rotating around the axis. The rolling cage is mainly composed of a cylindrical rolling cage net formed by a mesh, and the two ends are composed of a feed end plate with a feed port and a discharge end plate with a discharge port. The existing drying forming machine has added a heating and drying mechanism, but the heating and drying mechanism has a complex structure, and natural cooling is required after heating and drying, which affects the production efficiency of the forming machine.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-5 The utility model is a soft capsule pill forming machine, comprising a rotatable rolling cage 2, one end of which is provided with a feed port 204, both ends of which are rotatably mounted on a box body 101 through a rotating shaft, a feed port 204 is provided in the middle of the rotating shaft, and wet soft capsule pills made by the soft capsule machine are put into a drying cage 201 through the feed port 204.

[0025] The rolling cage 2 includes a drying cage 201 at one end close to the feed port 204 and a cooling cage 202 at one end away from the feed port 204. A spiral channel 6 is installed between the drying cage 201 and the cooling cage 202. The spiral channel 6 connects the drying cage 201 and the cooling cage 202. When the spiral channel 6 rotates forward under the driving action of the rolling cage 2, the soft capsule pills are blocked from entering the cooling cage 202 from the drying cage 201. When the spiral channel 6 reverses, the soft capsule pills enter the cooling cage 202 from the drying cage 201.

[0026] The spiral channel 6 includes an outer ring 601 and a spiral plate 602. The spiral plate 602 is fixedly installed in the outer ring 601. The outer ring 601 is coaxial and fixedly connected with the steel wire mesh of the drying cage 201 and the cooling cage 202. The inlet of the spiral plate 602 is connected to the interior of the drying cage 201, and the outlet is connected to the interior of the cooling cage 202.

[0027] The spiral channel 6 is fixedly connected to the drying cage 201 and keeps synchronous rotation. The drying cage 201 and the cooling cage 202 are an integrated structure. After the same batch of soft capsule pills enters the drying cage 201 for drying, they enter the cooling cage 202 for cooling. After the cooling of the batch of soft capsule pills is completed, they are taken out of the cooling cage 202, and then the next batch of soft capsule pills are sent to the drying cage 201 to enter the drying operation of the next batch.

[0028] In order to allow the soft capsule pills in the drying cage 201 to enter the cooling cage 202 more smoothly through the spiral channel 6, a lifting cylinder can be installed at the bottom of the end of the box 101 close to the feed port 204. When the soft capsule pills need to be fed into the cooling cage 202, the lifting cylinder rises, causing the end of the box 101 close to the feed port 204 to rise, and at the same time the rolling cage 2 reverses, and the soft capsule pills in the drying cage 201 automatically flow to the entrance of the spiral channel 6.

[0029] The heating mechanism of the forming machine includes a vortex tube 3 installed below the drying cage 201, and the hot air outlet of the vortex tube 3 faces the drying cage 201. The vortex tube 3 includes an air inlet 301 and hot air outlets 302 and cold air outlets 303 located at both ends. The air inlet can be connected to the air outlet port of the air compressor of the pharmaceutical factory. The existing heating and drying mechanism generally includes at least a heating structure and a blowing mechanism. The heating mechanism uses an electric heater or other heat source, and the blowing mechanism mostly uses a fan. The fan blows the heat of the electric heater to the drying cage 201 to dry the soft capsule pills. In this application, only the vortex tube is connected to the air compressor. Since the air compressor is one of the basic equipment of the pharmaceutical factory, the heating structure in this application is mainly to add a set of vortex tubes, and the vortex tube is mainly a mechanical structure, the structural complexity is reduced, and it can be used in conjunction with the air compressor in the pharmaceutical factory, which is convenient for improving the existing soft capsule pill drying equipment.

[0030] A first ejector 4 is installed between the hot air outlet of the vortex tube 3 and the drying cage 201. The working principle of the first ejector 4 and the second ejector 5 is the same as that of the jet pump. The first ejector 4 and the second ejector 5 themselves include a nozzle, a suction chamber, a mixing tube and a diffusion tube. The end of the nozzle away from the suction chamber is a nozzle inlet 401, the end of the suction chamber away from the nozzle is a suction inlet 402, and the end of the diffusion tube principle suction chamber is a diffusion outlet 403.

[0031] The hot air outlet of the vortex tube 3 is connected to the nozzle inlet of the first ejector 4, and the diffusion outlet of the first ejector 4 is toward the drying cage 201. When the hot air flow in the vortex tube 3 enters the first ejector 4 from the nozzle inlet, it will suck in the external room temperature air from the suction inlet. The temperature of the room temperature air is lower than the hot air flow ejected from the vortex tube 3. After mixing, it is used to adjust the temperature of the hot air flow to avoid the hot air flow temperature being too high.

[0032] A flow valve is installed at the suction inlet to control the amount of room temperature air entering from the suction inlet, thereby improving the accuracy of adjusting the temperature of the hot air flow.

[0033] In addition to being directly connected to the external environment (the external environment is the dust-free constant temperature workshop in the pharmaceutical factory), the suction inlet can also be connected to the air outlet pipe of the air compressor to provide room temperature air.

[0034] A distributor 7 is installed between the first ejector 4 and the drying cage 201 . The distributor 7 makes the hot air flow ejected from the diffusion outlet of the first ejector 4 more evenly distributed and blows evenly toward the soft capsule pills in the drying cage 201 .

[0035] The cold air outlet of the vortex tube 3 faces the cooling cage 202. The dried soft capsule pills in the cooling cage 202 are not only naturally cooled by the turning action of the cooling cage 202, but also accelerated cooled by the cold air flow blown out by the vortex tube 3, thereby improving the cooling efficiency.

[0036] When a vortex tube is used in the prior art, it is generally only used for heating or cooling, resulting in a low energy conversion efficiency of the vortex tube. However, in the present application, the hot air flow and the cold air flow ejected by the vortex tube can be used at the same time, effectively improving the energy conversion efficiency of the vortex tube.

[0037] The cold air outlet of the vortex tube 3 and the cooling cage 202 are installed with a second ejector 5, the cold air outlet of the vortex tube 3 is connected with the nozzle inlet of the second ejector 5, the diffusion outlet of the second ejector 5 faces the cooling cage 202, the structure of the second ejector 5 is the same as that of the first ejector 4, the suction inlet of the second ejector 5 is also installed with a flow valve, and the suction inlet is directly connected to the external environment, or connected to the outlet pipe of the air compressor, which is used to adjust the temperature of the cold air flow ejected from the vortex tube 3 to avoid the cold air flow temperature being too low.

[0038] A distributor 7 is installed between the second ejector 5 and the cooling cage 202. The distributor 7 allows the cold air flow ejected from the second ejector 5 to be more evenly distributed and blown toward the soft capsule pills.

[0039] It should be noted that the temperature of the hot air flow blowing towards the soft capsule pills should not be too high to avoid melting the soft capsule pills, and the temperature of the cold air flow blowing towards the soft capsule pills should not be too low to avoid condensed water vapor blowing towards the surface of the soft capsule. The staff should choose the appropriate temperature based on the actual production scale.

[0040] The forming machine also includes a housing 1, the main function of which is to prevent the rolling cage 2 from directly contacting the external environment and improve safety. The housing 1 includes a box body 101 and a box cover 102. The rolling cage 2, the vortex tube 3, the first ejector 4, the second ejector 5, and the uniform distributor 7 are all installed in the box body 101. Slide grooves 103 are installed at both ends of the box body 101, and the box cover 102 is slidably installed on the slide grooves 103.

[0041] There are two box covers 102, one large and one small. The big box cover 102 is sleeved on the outside of the small box cover 102. The two box covers 102 are respectively sleeved on the upper outside of the drying cage 201 and the cooling cage 202, and the sliding box cover 102 can reach the box cover 102.

[0042] The box cover 102 is made of a transparent material to facilitate observation of the situation inside the rolling cage 2.

[0043] The top of the box cover 102 is processed with an air vent 104 to facilitate the air flow in the box cover 102 to flow outward. An exhaust pipe can also be installed on the air vent to discharge the water vapor generated in the rolling cage 2.

[0044] Cage doors 203 are hingedly installed on the side walls of the drying cage 201 and the cooling cage 202. One end of the cage door 203 is hinged to the drying cage 201 and the cooling cage 202, and the other end is buckled. The cage door 203 is closed during operation. After cooling is completed, the cage door 203 is opened to take out the dried and cooled soft capsule pills from the cooling cage 202. The cage door 203 can also be opened to clean the inside of the drying cage 201 and the cooling cage 202.

[0045] Working principle: When in use, the soft capsule pills from the soft capsule machine are fed into the drying cage 201 from the feed port 204. The drying cage 201 rotates to drive the soft capsule pills to turn over. The hot air outlet of the vortex tube 3 blows out hot air, which is mixed with the external room temperature air through the first ejector 4 and cooled down, and then blown to the soft capsule pills in the drying cage 201 to dry the soft capsule pills.

[0046] After the soft capsule pills are dried, the rolling cage 2 is turned over, and the dried soft capsule pills enter the cooling cage 202 through the spiral channel 6. The cooling cage 202 continues to rotate, driving the dried soft capsule pills to turn over. The cold air outlet of the vortex tube 3 blows out cold air, which is mixed with the external room temperature air through the second ejector 5 and heated up, and then blown to the soft capsule pills in the cooling cage 202 to quickly cool the soft capsule pills.
