Description

Technical Field

[0001] This invention relates to the field of soft capsule production equipment technology, specifically to a soft capsule production rubber preparation equipment and preparation method. Background Technology

[0002] The outer shell of soft capsules is mainly made of gelatin, glycerin and other pharmaceutical excipients. In the production of soft capsule shells, various raw materials are usually weighed accurately and placed in a clean container. They are then heated to a certain temperature to dissolve them quickly. The gel is then extruded through a special extrusion head or pump head to form continuous, thin filaments, which are then dried quickly to form a solid shell.

[0003] However, if the raw materials are excessively agitated at high speed using a stirring fan blade during the rubber production process to accelerate the fusion and molding of the gel coat, unnecessary small air bubbles will be generated in the raw materials, resulting in voids in the gel coat. This can cause the soft capsules to become sticky when exposed to saliva, making them difficult to swallow. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a rubber preparation equipment for soft capsule production, including a support frame, a stirring tank fixedly connected inside the support frame, a sedimentation chamber fixedly connected to the inner wall of the support frame, a water inlet pipe fixedly connected to the outer wall of the stirring tank, and a feed pipe fixedly connected to the outer wall of the stirring tank.

[0005] The stirring mechanism includes a motor, a large particle filter plate for filtering materials, a stirring shaft, fan blades and scrapers, and stirring components for limiting the stirring speed and reducing air bubbles.

[0006] The inner wall of the mixing tank is fixedly connected to the outer wall of the large particle filter plate, the outer wall of the motor is fixedly connected to the outer wall of the mixing tank, the inner wall of the mixing tank is rotatably connected to the mixing shaft, the outer wall of the mixing shaft is fixedly connected to the rotating part of the motor, and the outer wall of the mixing shaft is fixedly connected to the fan blade scraper.

[0007] Preferably, the stirring assembly includes two clockwise rotating arc-shaped stirring rods fixedly connected to the outer wall of the stirring shaft. A fixing ring is fixedly connected to one end of the two clockwise rotating arc-shaped stirring rods away from the stirring shaft, and the outer wall of the fixing ring is fitted and connected to the inner wall of the stirring tank.

[0008] Preferably, a gear one is fixedly connected to the end of the stirring shaft furthest from the motor. A housing is fixedly connected to the outer wall of the stirring shaft. A housing two is meshed with the inner wall of the housing. A connecting rod is fixedly connected to the outer wall of the housing two. Two gears two are fixedly connected to the outer wall of the connecting rod. The outer walls of the two gears two mesh with the outer walls of the gear one. The inner wall of the housing two meshes with the interior of the mixing tank. A gear three is rotatably connected to the inner wall of the mixing tank. The outer wall of the gear three meshes with the outer walls of the two gears two. A connecting shaft two is fixedly connected to the outer wall of the gear three. The outer wall of the connecting shaft two penetrates through the inner wall of the mixing tank. Before use, connect the motor to the power supply and ensure that the motor is in working condition. Before use, connect the water inlet pipe to the corresponding hot water pipe and the feed pipe to the corresponding material pipe to ensure normal flow of both pipes. During operation, the motor drives the stirring shaft to... The mixing tank rotates as the material enters through the feed pipe and falls onto a large-particle filter plate. The blades connected to the mixing shaft then rotate and filter the material, pushing it to grind against the filter plate. As the material passes below, the large particles are ground smaller by the rotating blades before passing through the filter plate and mixing with the pure hot water. Two forward-rotating arc-shaped mixing rods are fixed to the outer wall of the mixing shaft, rotating at low speed. Two reverse-rotating arc-shaped mixing rods are attached to the outer wall of the mixing shaft, rotating in opposite directions. These rods are powered by gears mounted at the bottom of the mixing shaft. One pair of rotating blades rotates forward, while the other pair rotates in the opposite direction. This low-speed, high-torque rotation reduces air bubbles in the liquid. Simultaneously, the special rotating blades ensure thorough mixing of the material in the tank over a large area at low speed.

[0009] Preferably, the two ends of the connecting rod away from the outer shell are fixedly connected to a reverse arc-shaped stirring rod, and the two reverse arc-shaped stirring rods are fixedly connected to a fixing rod at the end away from the outer shell. The inner wall of the fixing rod is rotatably connected to the outer wall of the stirring shaft.

[0010] Preferably, a discharge pipe is fixedly connected to the outer wall of the mixing tank, and the inner wall of the discharge pipe is connected through the inner wall of the mixing tank. A stainless steel screen is fixedly connected to the inner wall of the discharge pipe, and a support plate is fixedly connected to the outer wall of the discharge pipe. Several springs are fixedly connected to the outer wall of the support plate. A vibrating screen shell is fixedly connected to the end of the spring away from the support plate. A vibrating screen is fixedly connected to the lower end of the vibrating screen shell, and a high and low sliding plate is fixedly connected to the outer wall of the vibrating screen shell.

[0011] Preferably, several push rods are fixedly connected to the outer wall of the fixed rod; the outer walls of several connecting shafts 2 are rotatably connected to the outer wall of the mixing tank; a cross-shaped rotating shaft is fixedly connected to the end of the connecting shaft 2 away from the gear 3; a drive shaft 1 is fixedly connected to the end of the cross-shaped rotating shaft away from the connecting shaft 2; an outer shell 3 is fixedly connected to the outer wall of the sedimentation chamber; a transmission hole is opened on the outer wall of the outer shell 3; the outer wall of the drive shaft 1 is rotatably connected to the inner wall of the transmission hole; the end of the drive shaft 1 away from the cross-shaped rotating shaft is rotatably connected to the inner wall of the outer shell 3; a gear 4 is fixedly connected to the outer wall of the drive shaft 1; a connecting shaft 1 is passed through the inner wall of the outer shell 3; a gear 5 is fixedly connected to the outer wall of the connecting shaft 1; the outer walls of gear 4 and gear 5 are meshed; a belt is rotatably connected to the end of the connecting shaft 1 away from gear 5; and a transmission shaft is rotatably connected to the inner wall of the sedimentation chamber. The shaft and belt are rotatably connected at the end away from the connecting shaft one to the outer wall of the drive shaft. Several push rods are fixedly connected to the outer wall of the connecting shaft two. The rotation of the connecting shaft two pushes the push rods to move downward by pushing the high and low slide plates. When the push rods pass the highest point of the high and low slide plates, the springs fixedly connected to the support plate below the high and low slide plates will drive the vibrating screen shell and the high and low slide plates to return to their original position. Because the push rods leave directly from the highest point of the high and low slide plates without buffering, and due to the characteristics of the springs, vibration will be generated when returning upward. The rotation of several push rods through the high and low slide plates will repeatedly cause the above vibration, providing high-frequency up and down vibration for the glue flowing downward through the vibrating screen. The vibration removes the tiny air bubbles generated in the glue, and the glue with the tiny air bubbles removed will flow downward through the holes of the vibrating screen.

[0012] Preferably, a second drive shaft is rotatably connected to the inner wall of the support frame, a fourth outer shell is fixedly connected to the outer wall of the sedimentation chamber, the outer wall of the second belt is rotatably connected to the outer wall of the second drive shaft, a rotating column is rotatably connected to the inner wall of the fourth outer shell, a second belt is rotatably connected to the outer wall of the drive shaft, the inner wall of the second belt is rotatably connected to the outer wall of the rotating column, the outer wall of the second belt is rotatably connected to the outer wall of the second drive shaft, a third drive shaft is penetratingly connected to the inner wall of the fourth outer shell, and the inner wall of the second belt is rotatably connected to the outer wall of the third drive shaft.

[0013] Preferably, a rotating drum is fixedly connected to the outer wall of the drive shaft, an extrusion cylinder is fixedly connected to the outer wall of the second drive shaft, a rotating shaft is rotatably connected to the inner wall of the support frame, the end of the third drive shaft away from the outer casing four is rotatably connected to the outer wall of the support frame, a conveyor belt is rotatably connected to the outer wall of the outer casing three, the end of the conveyor belt away from the third drive shaft is rotatably connected to the outer wall of the rotating shaft, a rotating shaft one is fixedly connected to the outer wall of the outer casing four, a cutting wheel is rotatably connected to the end of the rotating shaft one away from the outer casing four, and the cross-shaped connecting rotating shaft connected to the bottom end of the second connecting shaft has changed its connection position, so that the first drive shaft fixedly connected below the cross-shaped connecting rotating shaft is vertically downward connected, thus increasing the rotational force. The transmission is via gear four to gear five, gear five to connecting shaft one, and connecting shaft one to the drive shaft, causing the drive shaft to rotate the drum in the settling chamber. As the drum rotates, the adhesive adheres to the drum as a thin film due to its viscosity. The drum continues to roll upwards, and a scraper fixed to the settling chamber adheres to the outer wall of the drum, scraping off the excess adhesive. At the same time, a squeezing cylinder is installed at the upper end of the drum. Cooling water is injected into the squeezing cylinder through the addition port, or edible oil is added to the surface of the squeezing cylinder, causing the squeezing cylinder to squeeze and roll the gel coat that is rolling up, making the surface of the gel coat smooth and flat, while also preventing small air bubbles from remaining inside the gel coat.

[0014] Preferably, another rotating shaft is fixedly connected to the outer wall of the sedimentation chamber. A cutting wheel is rotatably connected to the end of this rotating shaft away from the sedimentation chamber. A discharge plate is fixedly connected to the outer wall of the sedimentation chamber, with a discharge port on each of its upper sides. A drive shaft is connected through-hole to the outer casing at the end away from the support frame. A feeding port is provided on the drive shaft. A scraper is fixedly connected to the inner wall of the sedimentation chamber, and a shovel is fixedly connected to the inner wall of the sedimentation chamber. The end of the shovel away from the sedimentation chamber is fixedly connected to the outer wall of the outer casing. The cutting wheel is tightly pressed against the surface of the rotating drum. When the drum rotates, due to friction, the cutting wheel also... The rollers rotate in opposite directions, cutting the edges of the gel coat to ensure consistent size and shape. A scraper fixed to the settling chamber is then placed on the scraper conveyor belt, with the scraper blade adhering to the surface of the roller. Excess gel coat edges are removed and fall through the discharge ports on both sides onto the discharge plate. Alternatively, the discharge plate can be removed, allowing the scrap to fall back into the settling chamber. Through these components and the extrusion cylinder, the gel coat surface is smoothed to achieve a uniform surface. The cutting wheel removes excess edges from both sides of the gel coat, ensuring neatness and uniformity. Finally, the scraper scrapes the formed gel coat from the roller onto the conveyor belt for transport to the next process.

[0015] A method for preparing a rubber coating preparation device for soft capsule production includes the following steps:

[0016] S1: Connect the pipes: Before use, connect the feed pipe and water inlet pipe to the corresponding pipes, and ensure that the motor power supply is in working condition.

[0017] S2: Start the equipment: Connect the power supply to ensure that the motor starts working and drives the stirring shaft to rotate at low speed. Material particles enter the feed pipe and are screened by the rotation and friction of the fan blade scraper and large particle filter plate. The large particles enter the lower stirring mechanism. The bottom end of the stirring shaft drives the reverse arc stirring rod to rotate in the opposite direction to the forward arc stirring rod, and ensures that the bottom mechanical energy is in normal working condition.

[0018] The present invention has the following beneficial effects:

[0019] (1) This invention addresses the problem of excessive air bubbles generated during the mixing of adhesive solutions. The inner wall of this equipment is equipped with a mixing mechanism and mixing components. Before use, the motor is connected to the power supply and ensured to be in working condition. Before use, the water inlet pipe is connected to the corresponding hot water pipe, and the feed pipe is connected to the corresponding material pipe, ensuring normal flow of both pipes. During operation, the motor drives the mixing shaft to rotate. When the material enters the mixing tank through the feed pipe, it falls onto the large particle filter plate. The fan blades connected to the mixing shaft rotate and filter the material, pushing it and grinding it against the large particle filter plate. This allows the material to enter the lower part of the filter while simultaneously allowing the large particles to pass through. The particles are ground down to smaller sizes during the rotation of the fan blades and scrapers, then pass through a large particle filter plate and enter below to mix with pure hot water. Two forward-rotating arc-shaped stirring rods are fixed to the outer wall of the stirring shaft and rotate at low speed under the drive of the stirring shaft. Two reverse-rotating arc-shaped stirring rods are attached to the outer wall of the stirring shaft and rotate in opposite directions. The reverse-rotating arc-shaped stirring rods are powered by gears installed at the bottom of the stirring shaft to reverse. One pair of fan blades rotates forward, and the other pair rotates in opposite directions. At the same time, the low-speed, high-torque rotation reduces the generation of air bubbles in the liquid. Meanwhile, the special rotating blades rotate the material in the tank over a large area at low speed, which fully agitates the material.

[0020] (2) The force of the above-mentioned stirring shaft drives the bottom connecting shaft two to rotate. Several push rods are fixedly connected to the outer wall of the connecting shaft two. The rotation of the connecting shaft two drives the push rods to rotate each time, pushing the high and low slide plates. This causes the push rods to move downwards from the lower part of the high and low slide plates. When the push rods rotate past the highest point of the high and low slide plates, the springs fixedly connected to the support plate below the high and low slide plates will drive the vibrating screen shell and the high and low slide plates to return to their original positions. Because the push rods leave directly from the highest point of the high and low slide plates without buffering, and due to the characteristics of the springs, vibration will be generated when returning upwards. Several push rods rotate through the high and low slide plates, and the above vibration is repeated, providing high-frequency vibration for the glue flowing downwards through the vibrating screen. The vibration removes the tiny air bubbles generated in the glue, and the glue with the tiny air bubbles removed will flow downwards through the holes of the vibrating screen.

[0021] (3) Taking advantage of the viscosity of the adhesive itself, the cross-shaped rotating shaft connected to the bottom of the connecting shaft 2 changes the connection position, so that the transmission shaft 1 fixedly connected below the cross-shaped rotating shaft is vertically downward. The rotational force is transmitted to gear 5 through gear 4, gear 5 is transmitted to connecting shaft 1, and connecting shaft 1 is transmitted to the transmission shaft, causing the transmission shaft to drive the rotating drum to rotate in the sedimentation chamber. When the drum rotates, the adhesive itself will adhere to the drum and form a thin film. The drum continues to roll upward. The scraper fixed on the sedimentation chamber is close to the outer wall of the drum and scrapes off the excess adhesive. At the same time, a squeezing cylinder is set at the upper end of the drum. Cooling water is injected into the squeezing cylinder through the addition port or edible oil is added to the surface of the squeezing cylinder, so that the squeezing cylinder squeezes and rolls the gel coat that rolls up, making the surface of the gel coat smooth and flat, and also avoiding small air bubbles remaining inside the gel coat.

[0022] (4) Using the force of the rotating drum, the cutting wheel is tightly attached to the surface of the rotating drum. When the rotating drum rotates, due to the friction, the cutting wheel will also rotate in the opposite direction, thereby cutting the edges of the glue on the rotating drum and making the edges of the gel coat consistent. The scraper fixed on the settling chamber is then placed on the scraper conveyor belt. The scraper part of the scraper is attached to the surface of the rotating drum. At the same time, the excess edges of the gel coat are removed and fall onto the discharge plate through the discharge ports on both sides. Alternatively, the discharge plate can be removed so that the scrap material falls back into the settling chamber. Through the above components and the extrusion cylinder, the surface of the gel coat is flattened to make it flat and consistent. The cutting wheel removes the excess edges on both sides of the gel coat to make it neat and consistent. Finally, the scraper scrapes the formed glue on the rotating drum onto the conveyor belt for transportation to facilitate the next process. Attached Figure Description

[0050] A rotating drum 61 is fixedly connected to the outer wall of drive shaft 57; an extrusion cylinder 62 is fixedly connected to the outer wall of drive shaft 2 59; a rotating shaft 63 is rotatably connected to the inner wall of support frame 1; the end of drive shaft 3 511 away from outer casing 4 512 is rotatably connected to the outer wall of support frame 1; a conveyor belt 64 is rotatably connected to the outer wall of outer casing 3 51; the end of conveyor belt 64 away from drive shaft 3 511 is rotatably connected to the outer wall of rotating shaft 63; a rotating shaft 1 65 is fixedly connected to the outer wall of outer casing 4 512; a cutting wheel 66 is rotatably connected to the end of rotating shaft 1 65 away from outer casing 4 512; the cross-shaped rotating shaft 49 connected to the bottom of connecting shaft 2 310 has changed its connection position, so that drive shaft 1 52 fixedly connected below the cross-shaped rotating shaft 49 is vertically downward connected, allowing rotation... Force is transmitted to gear 54 via gear 4 53, gear 54 transmits to connecting shaft 1 55, and connecting shaft 1 55 transmits to drive shaft 57, causing drive shaft 57 to drive the rotating drum 61 to rotate in the sedimentation chamber 12. When the rotating drum 61 rotates, the adhesive itself adheres to the rotating drum 61 in a thin film. The rotating drum 61 continues to roll upward. The scraper 611 fixed on the sedimentation chamber 12 is close to the outer wall of the rotating drum 61 and scrapes off the excess adhesive. At the same time, an extrusion cylinder 62 is provided at the upper end of the rotating drum 61. Cooling water is injected into the extrusion cylinder 62 through the addition port 69 or edible oil is added to the surface of the extrusion cylinder 62, so that the extrusion cylinder 62 squeezes and rolls the gel coat that rolls up, making the surface of the gel coat smooth and flat, while also avoiding the presence of small air bubbles inside the gel coat.

[0051] Another rotating shaft 65 is fixedly connected to the outer wall of the sedimentation chamber 12. A cutting wheel 66 is rotatably connected to the end of the rotating shaft 65 away from the sedimentation chamber 12. A discharge plate 68 is fixedly connected to the outer wall of the sedimentation chamber 12, with a discharge port 67 on each of its upper sides. A drive shaft 59 is connected through-hole to the outer casing 512 at the end away from the support frame 1. An addition port 69 is provided on the drive shaft 59. A scraper 611 is fixedly connected to the inner wall of the sedimentation chamber 12, and a scraper 612 is fixedly connected to the inner wall of the sedimentation chamber 12. The end of the scraper 612 away from the sedimentation chamber 12 is fixedly connected to the outer wall of the outer casing 512. The cutting wheel 66 is tightly pressed against the surface of the rotating drum 61. When the rotating drum 61 rotates, the cutting wheel 66 is pressed against the surface of the rotating drum 61 due to friction. As the drum 61 rotates, the gel coat also rotates in the opposite direction, thus achieving the goal of cutting the edges of the gel coat on the drum 61 to ensure that the formed edges of the gel coat are consistent in size. The scraper 612, which is fixed on the settling chamber 12, is attached to the scraper conveyor belt 64. The scraper part of the scraper 612 is attached to the surface of the drum 61, and the excess gel coat edges are removed and fall onto the discharge plate 68 through the discharge ports 67 on both sides. Alternatively, the discharge plate 68 can be removed so that the scrap material falls back into the settling chamber 12. Through the above components, the extrusion cylinder 62 is used to flatten the surface of the gel coat to make it flat and consistent. The cutting wheel 66 removes the excess edges of the gel coat on both sides to make it neat and consistent. Finally, the scraper 612 scrapes the formed gel coat off the drum 61 onto the conveyor belt 64 for transportation to the next process.

[0052] A method for preparing an apparatus for making rubber sheets for soft capsule production, characterized by comprising the following steps:

[0053] S1: Connect the pipes: Before use, connect the feed pipe 14 and the water inlet pipe 13 to the corresponding pipes, and ensure that the power supply of the motor 21 is in working condition.

[0054] S2: Start the equipment: Connect the power supply to ensure that the motor 21 starts working and drives the stirring shaft 23 to rotate at low speed. The material particles enter the feed pipe 14. When the large particles are rotated and rubbed by the fan blade scraper 24 and the large particle filter plate 22, they are screened and enter the lower stirring mechanism. The bottom end of the stirring shaft 23 drives the reverse arc stirring rod 36 to stir in the opposite direction of the forward arc stirring rod 32, and ensures that the bottom mechanical energy is in normal working condition.

[0055] One specific application of this embodiment is as follows: Before use, connect the motor 21 to the power supply and ensure that the motor 21 is in working condition. Connect the water inlet pipe 13 to the corresponding hot water pipe and the feed pipe 14 to the corresponding material pipe to ensure normal flow of the two pipes. Ensure that the motor 21 is connected to the power supply and in working condition. During operation, the motor 21 drives the stirring shaft 23 to rotate. When the material enters the mixing tank 11 through the feed pipe 14, it will fall onto the large particle filter plate 22. The fan blade scraper 24 connected to the stirring shaft 23 will rotate and filter the material, thus promoting the material and large particles to mix. The filter plate 22 grinds the material, allowing large particles to be ground down as the scraper blades 24 rotate. These particles then pass through the large particle filter plate 22 and mix with the purified hot water below. Two forward-rotating arc-shaped stirring rods 32 are fixed to the outer wall of the stirring shaft 23, rotating at low speed under its drive. Two reverse-rotating arc-shaped stirring rods 36 are attached to the outer wall of the stirring shaft 23, rotating in opposite directions. The reverse-rotating arc-shaped stirring rods 36 are powered by gears mounted at the bottom of the stirring shaft 23. One pair of rotating fan blades rotates forward, while the other pair rotates in the opposite direction. Simultaneously, the low-speed, high-torque rotation reduces the generation of air bubbles in the adhesive. Furthermore, the large-area, low-speed rotation of the special rotating blades ensures thorough mixing of the material in the tank. The force of the stirring shaft 23 drives the bottom connecting shaft 310 to rotate. Several push rods 41 are fixedly connected to the outer wall of the connecting shaft 310. Each rotation of the connecting shaft 310 pushes the push rods 41, causing them to move downwards by pushing the lower part of the high-low slide plate 43. When the push rod 41 passes the highest point of the high-low slide plate 43, the high-low slide plate... The spring fixedly connected to the support plate 45 below the plate 43 will drive the vibrating screen housing 46 and the high and low slide plate 43 to return to the upper position. Because the push rod 41 leaves directly from the highest part of the high and low slide plate 43 without buffering, and due to the characteristics of the spring, it will generate vibration when returning to the upper position. Several push rods 41 rotate through the high and low slide plate 43, repeating the above vibration, providing high-frequency up and down vibration for the glue flowing downward through the vibrating screen 48. The vibration removes the tiny air bubbles generated in the glue, and the glue with the tiny air bubbles removed will flow downward through the holes of the vibrating screen 48.

[0056] The cross-shaped rotating shaft 49 connected to the bottom of the connecting shaft 2 310 has changed its connection position, so that the transmission shaft 1 52 fixedly connected below the cross-shaped rotating shaft 49 is vertically downward connected. The rotational force is transmitted to the gear 54 through the gear 4 53, the gear 54 transmits to the connecting shaft 1 55, and the connecting shaft 1 55 transmits to the transmission shaft 57, causing the transmission shaft 57 to drive the rotating drum 61 to rotate in the sedimentation chamber 12. When the rotating drum 61 rotates, the adhesive itself will adhere to the rotating drum 61 in a thin film due to its viscosity. The rotating drum 61 continues to roll upward. The scraper 611 fixed on the sedimentation chamber 12 is close to the outer wall of the rotating drum 61 and scrapes off the excess adhesive. At the same time, the upper end of the rotating drum 61 is provided with an extrusion cylinder 62. Cooling water is injected into the extrusion cylinder 62 through the addition port 69 or edible oil is added to the surface of the extrusion cylinder 62, so that the extrusion cylinder 62 squeezes and rolls the gel coat that rolls up, making the surface of the gel coat smooth and flat, and also avoiding the presence of small air bubbles inside the gel coat.

[0057] The cutting wheel 66 is tightly attached to the surface of the rotating drum 61. When the rotating drum 61 rotates, due to the friction, the cutting wheel 66 will also rotate in the opposite direction, thus achieving the goal of cutting the edges of the adhesive on the rotating drum 61, ensuring that the size and edges of the gel coat are consistent. The scraper 612, which is fixed on the settling chamber 12, is attached to the scraper conveyor belt 64. The scraper part of the scraper 612 is attached to the surface of the rotating drum 61. At the same time, the excess gel coat edges are removed and fall onto the discharge plate 68 through the discharge ports 67 on both sides. Alternatively, the discharge plate 68 can be removed so that the scrap material falls back into the settling chamber 12. Through the above components, the surface of the gel coat is flattened by the extrusion cylinder 62 to make the surface flat and consistent. The cutting wheel 66 removes the excess edges of the gel coat on both sides to make it neat and consistent. Finally, the scraper 612 scrapes the formed adhesive on the rotating drum 61 onto the conveyor belt 64 for transportation to the next process.
