Description

Technical Field

[0001] The invention relates to the technical field of capsule production equipment, in particular to a single-piece capsule sorting device. Background Art

[0002] A medicinal capsule is a cylindrical shell with hemispherical ends, which is composed of two open shells nested together. People in the industry call half of the capsule shell a "single piece".

[0003] After the capsules are formed, they are usually of different lengths and need to be cut. The capsule cutting machine must separate the semi-finished products from the rubber heads during the process of cutting the capsule blanks. However, due to the influence of factors such as capsule dryness, static electricity, and ambient temperature, there are always rubber heads that fall into the semi-finished products, which need to be manually sorted later, resulting in low production efficiency and waste of manpower.

[0004] The application (patent) number is: CN202010654641.4. A rubber head screening device, wherein the suction nozzle sucks the semi-finished capsule or rubber head in the hopper under the action of negative pressure, and drives the rotating wheel to rotate through the motor, and the rotating wheel drives the suction nozzle fixed with the semi-finished capsule or rubber head to pass through the scraper, and the scraper scrapes off the semi-finished capsule or rubber head on the suction nozzle and drops it into the flow trough, and the semi-finished capsule or rubber head slides down along the length direction of the flow trough. When the semi-finished capsule and the rubber head pass through the rubber head dropping port, the rubber head falls from the rubber head dropping port because the size of the rubber head is smaller than that of the semi-finished capsule. The semi-finished capsule passes through the rubber head dropping port and falls into the collecting box from the front end of the flow trough. Although it can improve production efficiency and save manpower, the rubber head screening device conveys and screens one by one, so the production efficiency needs to be improved.

[0028] The air inlet 4426 is connected to the recovery box 44211 through a pipe 44210. The recovery box 44211 is provided with an exhaust fan 44212 connected thereto. The recovery box 44211 is provided with a mesh cover 44213 covering the input port of the exhaust fan 44212.

[0029] The sleeves 4424 are arranged in two rows, front and back, and the sleeves 4424 in the two rows are arranged alternately. The sleeves 4424 correspond to the corresponding sieve holes 41 one by one.

[0030] The baffle frame 43 is provided with a receiving hopper 46 located below the screening plate 42 . The output end of the receiving hopper 46 is connected to a conveying pipe 47 , and the front end of the conveying pipe 47 is connected to a blower 45 .

[0031] Working process of the present invention: In the working process of the capsule single-piece sorting device of the present invention, the vibration table 1 drives the collecting hopper 2 and the rubber head screening mechanism 3 to vibrate, and the capsule single piece and the cut rubber head enter the collecting hopper 2, and then pass through the discharge port 7, the guide plate 10 and the feed port 11 in sequence to enter between the upper mesh plate 31 and the lower mesh plate 32, and are screened between the upper mesh plate 31 and the lower mesh plate 32 under the action of vibration. When the cut rubber head passes through the mesh II321, the cut rubber head can be turned over and shaken into the mesh II321, and then fall into the rubber head hopper below the lower mesh plate 32 through the mesh II321. When the capsule single piece passes through the mesh II321, the capsule single piece cannot be turned over and cannot be shaken into the mesh II321. The capsule single piece passes through the lower mesh plate 32, and finally is output from the rear end of the lower mesh plate 32 and falls onto the screening plate 42.

[0032] The vibration table 1 drives the screening plate 42 to vibrate, and the capsule sheets on the screening plate 42 are vibrated into the sieve holes 41, and then fall into the receiving hopper 46 and enter the conveying pipe 47. Under the action of the air blower 45, the capsule sheets are conveyed to the next process along the conveying pipe 47, while some capsule sheets with poor appearance (such as: defective parts that are flattened and widened, etc.) cannot pass through the sieve holes 41, so the defective products are intercepted.

[0033] When cleaning defective products, the exhaust fan 44212 and the cylinder 4414 are started, and the compressed air enters the lower cavity 4428 from the air inlet 4425, and is finally blown out from the lower end of the sleeve 4424. The cylinder 4414 pushes the movable seat 4416 to move downward, and the movable seat 4416 drives the sleeve 4424 and the suction pipe 4421 to move downward through the hollow body 4422, so that the suction pipe 4421 is close to the sieve holes 41 in the corresponding area (the sieve holes in the area are in two rows and correspond to the suction pipe 4421 one by one). In this way, under the action of negative pressure, the defective products in the corresponding sieve holes 41 are sucked into the suction pipe 4421, and then enter the return pipe through the pipeline 44210. During the descent of box 44211, the air flow blown out through sleeve 4424 blows away the capsule monomers at the edge of the corresponding sieve hole 41 to prevent the capsule monomers from entering the bottom of the suction tube 4421 at the end of its descent, so as to avoid crushing the capsule monomers. After the current sieve hole 41 is cleaned, cylinder 4414 pulls moving seat 4416 to move upward, and moving seat 4416 drives sleeve 4424 and suction tube 4421 to move upward and return to their original positions through hollow body 4422, and then starts electric push rod 4411 to drive slide seat 4413 to move forward, so that suction mechanism 442 enters the next area, and then cleans the sieve holes 41 in the corresponding area.

[0034] The baffle II91 is used to prevent the capsule pieces and cut rubber heads output by the pneumatic conveying system from falling smoothly into the collecting hopper 2. The air leakage hole 93 is used to unload the airflow output by the pneumatic conveying system to prevent the cut rubber heads or capsule pieces from falling outside the collecting hopper 2 due to the airflow.

[0035] The mesh I311 facilitates the cleaning of unqualified products stuck in the mesh II321, and the screening working status can be observed, and further provides an escape space for unqualified products to flip into the mesh II321.

[0036] The above embodiments are intended to illustrate the present invention, not to limit the present invention. Any solution that is a simple transformation of the present invention belongs to the protection scope of the present invention.
