Description

Technical Field

[0001] The utility model relates to the technical field of pharmaceutical manufacturing, in particular to a feeding and strip making mechanism with a novel flap. Background Art

[0002] For Chinese medicine pills, it is necessary to first prepare a moderately hard and soft medicine strip, and then cut the medicine strip into suitable pills. The feeding flap used in the existing Chinese medicine pill making machine is a straight-shaped flap composed of two blades, which realizes feeding by rotation. The straight-shaped flap is prone to material return when the material enters the silo, and it is impossible to ensure that the material enters the silo continuously and stably, and thus it is impossible to ensure that the silo is filled and provide sufficient strip-making pressure for the strip feeding mechanism, so that the pressure is insufficient when the material is pushed to the strip-out plate, resulting in uneven shape (diameter, density, conveying speed) of the medicine strips on the strip-out plate, which ultimately leads to different sizes of pills and a large number of unqualified pills. Utility Model Content

[0003] The utility model provides a feeding strip making mechanism with a novel flap, which can solve the problems of material return caused by the feeding flap during the feeding process, unstable feeding leading to insufficient material filling in the silo and insufficient strip making pressure, and ensure uniform strip production and consistent pill shape and weight.

[0022] like Figure 1 As shown, a feeding and strip making mechanism with a new flap, the feeding and strip making mechanism includes a feeding barrel 1, a feeding bin 3, a feeding flap 4, a strip making bin 6, a screw propeller 7, and a strip output template 8. The upper end of the feeding barrel 1 is provided with a feeding port 5, and the lower end is connected to the feeding bin 3. The feeding flap 4 is arranged in the feeding bin 3, and the feeding flap 4 includes a rotating shaft 41 and a cross-shaped flap 42. Figure 2 As shown, the cross-shaped flap 42 is composed of four blades 421 connected in a cross manner, and the thickness of each blade 421 gradually decreases from the inside to the outside. The cross-shaped flap 42 is fixed on the rotating shaft 41, and both ends of the rotating shaft 41 are rotatably connected to the side walls of the feed bin 3 and connected to the second driving motor. The bottom of the feed bin 3 is connected to the strip making bin 6, and a spiral propeller 7 is provided in the strip making bin 6. The front end of the spiral propeller 7 is provided with a strip output template 8, and the shaft at the rear end is connected to the third driving motor. A material guide trough 9 is provided below the strip output template 8.

[0023] The Chinese medicine pill making process includes feeding and strip making, strip feeding, and pill rolling. When the present application is used for feeding and strip making, the Chinese medicine raw materials are first added into the feeding barrel 1 from the feeding port 5, and the driving motor 2 drives the rotating shaft 41 of the feeding flap 4 to rotate, driving the feeding flap 4 to rotate and flip the Chinese medicine raw materials down and squeeze them into the strip making bin 6, and the driving motor 3 drives the shaft of the spiral propeller 7 to rotate, and the spiral propeller 7 pushes the Chinese medicine raw materials out of the strip output template 8 and forms a medicine strip. After the medicine strip is extruded, it is introduced into the feeding mechanism and the pill rolling mechanism through the guide groove 9 for subsequent processes. The feeding mechanism delivers the medicine strip to the pill rolling mechanism, and the pill rolling mechanism is a mechanism for the pill making tool to do reciprocating kneading. When the medicine strip is delivered to the pill rolling tool, the medicine strip is kneaded into a spherical pill by the pill rolling tool.

[0024] In order to further improve the uniformity of feeding, a spiral feeder 2 is provided in the feeding barrel 1, and the spiral feeder 2 includes a screw 21 and a spiral guide piece 22 arranged around the screw 21. The screw 21 is connected to a driving motor 1, and the driving motor 1 drives the screw 21 of the spiral feeder 2 to rotate, so that the Chinese medicine material falls into the feeding bin 3 in an orderly and uniform manner along the spiral guide piece 22. The feeding port 5 is funnel-shaped for convenient feeding.

[0025] The spiral guide piece 22 is in clearance with the inner wall of the feed barrel 1, and the outer end of the blade 421 is a pointed end, which is in clearance with the side wall of the feed bin 3, thereby preventing material return and ensuring that the raw materials enter the bin in an orderly manner.

[0026] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, technicians familiar with the field may make various corresponding changes and deformations based on the present invention, but these corresponding changes and deformations should all fall within the scope of protection of the claims attached to the present invention.
