[0013] A method for preparing a rubber preparation device for soft capsule production comprises the following steps: S1: Connect the pipeline: Before use, connect the feed pipe and the water inlet pipe to the corresponding pipelines, and ensure that the power supply of the motor is in working condition.

[0014] S2: Start the equipment: Connect the power supply to ensure that the motor starts working and drives the stirring shaft to rotate at a low speed. The material particles enter the feed pipe. When the fan blade scraper and the large particle filter plate rotate and rub against them, the large particles are screened and enter the lower stirring mechanism. The bottom end of the stirring shaft drives the reverse arc stirring rod to rotate and stir in the opposite direction of the forward arc stirring rod, and ensure that the bottom mechanical energy is in normal working condition.

[0015] The present invention has the following beneficial effects: (1) The present invention aims to solve the problem of excessive bubbles generated when stirring the glue liquid. A stirring mechanism and a stirring assembly are arranged on the inner wall of the device. Before use, the motor is connected to the power supply and ensured to be in working state. 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 to ensure the normal circulation of the two pipes. During operation, the motor drives the stirring shaft to rotate. When the material enters the stirring barrel through the feed pipe, it will fall on the large particle filter plate and be filtered and fused by the fan blade scraper connected to the stirring shaft, pushing the material and the large particle filter plate to grind, so that the material enters the bottom while letting the large particles The particles are ground into smaller pieces during the rotation of the blade scraper, and then enter the bottom through the large particle filter plate to be mixed and stirred with pure hot water. Two forward-rotating arc-shaped stirring rods are fixed on the outer wall of the stirring shaft and rotate at a low speed driven by the stirring shaft. Two reverse-rotating arc-shaped stirring rods are attached to the outer wall of the stirring shaft for reverse rotation. The reverse-rotating arc-shaped stirring rods are powered by gears installed at the bottom of the stirring shaft for reverse rotation. One pair of rotating blades rotates forward, and the other pair rotates in the opposite direction. At the same time, they rotate at a low speed with a large torque. The low-speed rotation also reduces the generation of bubbles in the glue. At the same time, the materials in the tank are fully stirred by the special rotating blades that rotate over a large area and at a low speed.

[0016] (2) The force of the stirring shaft is used to drive the bottom connecting shaft 2 to rotate. The outer wall of the connecting shaft 2 is fixedly connected with a plurality of push rods. Each time the push rod rotates through the rotation of the connecting shaft 2, the push rod pushes the high and low slides from the lower part of the high and low slides to move downward. When the push rod rotates past the highest point of the high and low slides, the spring fixedly connected to the support plate below the high and low slides will drive the vibrating screen housing and the high and low slides to reset upward. Because the push rod leaves directly from the highest point of the high and low slides without buffering, and due to the characteristics of the spring, it will generate shaking when resetting upward. Several push rods rotate through the high and low slides, and the above shaking occurs repeatedly, providing high-frequency vibration up and down for the glue liquid flowing downward through the vibrating screen, and removing tiny bubbles generated in the glue liquid through vibration. At the same time, the glue liquid with tiny bubbles removed will be diverted to the bottom along the holes of the vibrating screen.

[0017] (3) Taking advantage of the viscosity of the above-mentioned glue liquid, the cross-connected rotating shaft connected to the bottom end of the connecting shaft 2 changes the connection position, so that the transmission shaft 1 fixedly connected below the cross-connected rotating shaft is vertically connected downward, and the rotational force is transmitted to the gear 5 through the gear 4, and the gear 5 is transmitted to the connecting shaft 1, and the connecting shaft 1 is transmitted to the transmission shaft so that the transmission shaft drives the rotating drum to rotate in the sedimentation chamber. When the rotating drum rotates, the glue liquid will adhere to the rotating drum in a thin film due to its own viscosity. The rotating drum continues to roll upward, and the scraper fixed on the sedimentation chamber is attached not far from the outer wall of the rotating drum to scrape off the excess glue liquid. At the same time, an extrusion cylinder is set at the upper end of the rotating drum. Cooling water is injected into the extrusion cylinder through the addition port or edible oil is added to the surface of the extrusion cylinder, so that the extrusion cylinder extrude and roll the gel coat that rolls up, making the surface of the gel coat flat and smooth, while also avoiding small bubbles remaining inside the gel coat.

[0018] (4) By utilizing the force of the above-mentioned rotating drum, the cutting wheel is tightly attached to the surface of the rotating drum. When the rotating drum rotates, due to the effect of friction, the cutting wheel will also rotate in the opposite direction when the rotating drum rotates, thereby cutting the edges and corners of the glue on the rotating drum and making the edges and corners of the gel coat consistent. When the scraper fixed on the sedimentation chamber is 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 gel coat edges and corners removed are dropped onto the discharge plate through the discharge ports on both sides and discharged. The discharge plate can also be removed so that the edges and corners fall back into the sedimentation chamber. Through the above-mentioned components and the extrusion cylinder, the surface of the gel coat is flattened to make its surface 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 glue formed on the rotating drum is scraped off by the scraper onto the conveyor belt for transportation to facilitate the next process. BRIEF DESCRIPTION OF THE DRAWINGS

When drum 61 rotates, the adhesive liquid will adhere to drum 61 in the form of a thin film due to its own viscosity. Drum 61 continues to roll upward, and scraper 611 fixed on sedimentation chamber 12 is attached not far from the outer wall of drum 61 to scrape off excess adhesive liquid. At the same time, an extrusion cylinder 62 is provided at the upper end of drum 61.

[0033] A method for preparing a device for preparing rubber for soft capsule production, characterized in that it comprises the following steps: S1: Connect the pipeline: Before use, connect the feed pipe 14 and the water inlet pipe 13 to the corresponding pipelines, and ensure that the power supply of the motor 21 is in working state.

[0034] 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 a low speed. The material particles enter the feed pipe 14. When the fan blade scraper 24 and the large particle filter plate 22 rotate and rub against them, the large particles are screened and enter the lower stirring mechanism. The bottom end of the stirring shaft 23 drives the reverse arc stirring rod 36 to perform reverse rotation stirring compared with the forward arc stirring rod 32, and ensure that the bottom mechanical energy is in normal working condition.

[0035] A specific application of this embodiment is: before use, the motor 21 is powered on and ensured to be in working state, the water inlet pipe 13 is connected to the corresponding hot water pipe, the feed pipe 14 is connected to the corresponding material pipe, the normal circulation of the two pipes is ensured, and the motor 21 is powered on and in working state. When working, the motor 21 drives the stirring shaft 23 to rotate. When the material enters the stirring barrel 11 through the feed pipe 14, it will fall on the large particle filter plate 22 and be rotated and filtered and fused by the fan blade scraper 24 connected to the stirring shaft 23, pushing the material and the large particles to move. The particle filter plate 22 grinds the material so that the material enters the bottom and the large particles are ground into smaller particles during the rotation of the blade scraper 24. Then the large particles pass through the large particle filter plate 22 and enter the bottom to be mixed with the pure hot water. The outer wall of the stirring shaft 23 is fixed with two forward-rotating arc stirring rods 32. Driven by the stirring shaft 23, the stirring shaft 23 rotates at a low speed. The outer wall of the stirring shaft 23 is fitted with two reverse-rotating arc stirring rods 36 for reverse rotation. The reverse-rotating arc stirring rods 36 are powered by the gears installed at the bottom of the stirring shaft 23 for reverse rotation. One pair of rotating blades rotates forward, and the other pair rotates in the opposite direction. At the same time, the low-speed high-torque rotation also reduces the generation of bubbles in the glue. At the same time, the special rotating blades rotate the materials in the tank over a large area at a low speed to fully stir the materials. The force of the stirring shaft 23 drives the bottom connecting shaft 210 to rotate. The outer wall of the connecting shaft 210 is fixedly connected with a plurality of pushing rods 41. The rotation of the connecting shaft 210 pushes the high-low slide 43 each time the pushing rod 41 rotates, so that the pushing rod 41 is pushed from the lower part of the high-low slide 43 to move downward. When the pushing rod 41 rotates past the highest point of the high-low slide 43, the high-low slide The spring fixedly connected to the support plate 45 below the plate 43 will drive the vibration screen housing 46 and the high and low slide plates 43 to reset upwards, because the push rod 41 directly leaves the highest part of the high and low slide plates 43 without buffering, and due to the characteristics of the spring, shaking will be generated when resetting upwards. Several push rods 41 rotate through the high and low slide plates 43, and the above-mentioned shaking will be repeated, providing high-frequency vibration up and down for the glue liquid flowing downward through the vibration screen 48, and removing tiny bubbles generated in the glue liquid through vibration. At the same time, the glue liquid with tiny bubbles removed will be diverted to the bottom along the holes of the vibration screen 48.

[0036] The cross-connected rotating shaft 49 connected to the bottom end of the connecting shaft 2 310 changes the connection position, so that the transmission shaft 1 52 fixedly connected below the cross-connected rotating shaft 49 is connected vertically downward, and the rotational force is transmitted to the gear 54 through the gear 4 53, and the gear 54 is transmitted to the connecting shaft 1 55, and the connecting shaft 1 55 is transmitted to the transmission shaft 57 so that the transmission shaft 57 drives the rotating drum 61 to rotate in the sedimentation chamber 12. When the rotating drum 61 rotates, the glue liquid will adhere to the rotating drum 61 in a thin film due to its own viscosity. The rotating drum 61 continues to roll upward, and the scraper 611 fixed on the sedimentation chamber 12 is attached not far from the outer wall of the rotating drum 61 to scrape off the excess glue liquid. 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 extrude and roll the gel coat that rolls up, making the gel coat surface flat and smooth, and also avoiding small bubbles remaining inside the gel coat.

[0037] The cutting wheel 66 fits tightly on the surface of the rotating drum 61. When the rotating drum 61 rotates, due to the effect of friction, the cutting wheel 66 rotates in the opposite direction when the rotating drum 61 rotates, so as to achieve the effect of cutting the edges and corners of the glue liquid on the rotating drum 61, so that the size and corners of the gel coat are consistent. The scraper 612 fixed on the sedimentation chamber 12 is scraped on the conveyor belt 64, and the scraper part of the scraper 612 fits on the surface of the rotating drum 61. At the same time, the removed excess gel coat edges and corners are dropped on the discharge plate 68 through the discharge ports 67 on both sides and discharged. The discharge plate 68 can also be removed to make the edges and corners fall back into the sedimentation chamber 12. Through the above-mentioned components, the surface of the gel coat is flattened by the extrusion cylinder 62 to make its surface flat and consistent. The cutting wheel 66 removes the excess edges and corners on both sides of the gel coat to make it neat and consistent. Finally, the glue liquid formed on the rotating drum 61 is shoveled off to the conveyor belt 64 by the scraper 612 for transportation to facilitate the next process.
