Description

Technical Field

[0001] This utility model relates to the field of powder pharmaceutical production equipment, and in particular to a stirring blade mounting structure for powder dispensing equipment. Background Technology

[0002] Powder filling machines are core equipment in powdered pharmaceutical production lines. Existing powder filling machines include a filling mechanism and a powder feeding mechanism. The main function of the powder feeding mechanism is to transfer the powder raw materials temporarily stored in the powder hopper to the powder silo via a feeding device, and then the powder raw materials are sent to the filling mechanism via a conveying mechanism in the powder silo. Finally, the filling mechanism delivers the powder raw materials into the packaging bags of the pharmaceuticals according to the set amount.

[0003] In existing powder dispensing mechanisms, the stirring blades are in direct contact with the medicine for extended periods. Since the stirring blades are irregularly shaped, they typically need to be welded and fixed to a blade connector before being installed on the periphery of the stirring drive shaft, which transmits power to the stirring blades.

[0004] The installation and fixing of the aforementioned impeller connector and the stirring drive shaft generally adopts the method of fastening bolts. This traditional fixing method has two major drawbacks: First, the bolt connection has tiny thread gaps and mounting holes, which can easily trap powder and form a sanitary dead corner that is difficult to clean thoroughly, posing a risk of microbial contamination in aseptic production; Second, bolt fixing requires the use of tools in a Class A clean area for installation and removal, which is not only cumbersome and time-consuming, but also prone to introducing particles or contamination due to tool operation, posing a threat to the aseptic environment.

[0005] Since the agitator blades and blade connectors need to be disassembled regularly for cleaning and sterilization, the traditional threaded connection method is more cumbersome and time-consuming when dealing with such frequent disassembly and assembly, which delays the normal production schedule, and therefore needs to be improved. Utility Model Content

[0006] To address the problems existing in the prior art, the bolt connection between the impeller connector and the stirring drive shaft is cumbersome and time-consuming during frequent disassembly and assembly for cleaning and sterilization, thus delaying normal production progress. The purpose of this utility model is to provide a stirring impeller installation structure for powder dispensing equipment. A male connector is provided at the end of the stirring drive shaft and a female connector is provided on the impeller connector, so that the stirring drive shaft and the impeller connector can be connected and fixed by simple plug-in mating, which greatly improves the disassembly and assembly efficiency.

[0007] To achieve the above objectives, the technical solution of this utility model is as follows: A stirring blade mounting structure for a powder dispensing equipment is provided for mounting a blade connector below a stirring drive shaft. The structure includes a male connector and a female connector. The male connector is located on the stirring drive shaft at its bottom, and the female connector is located on the blade connector at its top. The male and female connectors are compatible and interlock. The male connector has a groove, and the female connector has a locking pin. When the male and female connectors are interlocked, the locking pin enters the groove and engages with it.

[0008] The present invention is further configured such that: the female connector is a hole formed on the blade connector, and the inner diameter of the female connector is adapted to the outer diameter of the male connector.

[0009] The present invention is further configured such that: the slot includes an inlet section and a locking section, the length direction of the inlet section is vertical and the axial direction of the stirring drive shaft is vertical, the length direction of the locking section is perpendicular to the inlet section, and the end of the inlet section is connected to the locking section.

[0010] The present invention is further configured such that the locking pin enters the slot from the inlet section.

[0011] The present invention is further configured such that: the card slot further includes a limiting segment, the length direction of the limiting segment is the same as the length direction of the guiding segment, and the limiting segment and the guiding segment are respectively located at both ends of the locking segment, and the limiting segment and the locking segment are connected.

[0012] The present invention is further configured such that the length of the limiting segment is less than the length of the guiding segment.

[0013] In summary, the beneficial effects achieved by this utility model are as follows: (1) The male connector is directly set on the stirring drive shaft, and the female connector is directly set on the blade connector. The connection between the stirring drive shaft and the blade connector can be realized without adding any other extra structures. (2) The male and female connectors are connected by a plug-in method. The locking between the male and female connectors is achieved by a locking pin and a locking groove. The operation is simple and quick, and the stirring blades can be quickly installed and disassembled without any tools. This completely eliminates the threaded connection and thus eliminates the resulting dead corners for hygiene. Attached Figure Description

[0018] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] As attached Figure 1-3 As shown, a stirring blade mounting structure for a powder dispensing equipment is used to install the blade connector 2 below the stirring drive shaft 1.

[0020] Both the impeller connector 2 and the stirring drive shaft 1 are existing structures, both vertically arranged and with their axes coincident. At least two stirring blades (not shown in the figure) are welded and fixed to the outer sidewall of the impeller connector 2, and the stirring drive shaft 1 is used to transmit power to the impeller connector 2.

[0021] The bottom end of the stirring drive shaft 1 is a male connector 3, and the top opening of the blade connector 2 is a female connector 4. The inner diameter of the female connector 4 is matched with the outer diameter of the male connector 3, so that the male connector 3 and the female connector 4 can be plugged into each other.

[0022] The outer wall of the male connector 3 is symmetrically provided with two recessed slots, each of which includes an inlet section 31, a locking section 32 and a limiting section 33.

[0023] The length directions of both the inlet section 31 and the limiting section 33 are the same as the axis of the stirring drive shaft 1, and the length direction of the locking section 32 is perpendicular to the inlet section 31. The limiting section 33 and the inlet section 31 are located at the two ends of the locking section 32, and the top ends of the limiting section 33 and the inlet section 31 are simultaneously connected to the locking section 32. Moreover, the length of the limiting section 33 is less than the length of the inlet section 31.

[0024] Two protruding locking pins 41 are symmetrically arranged on the inner wall of the connecting female head 4. The locking pins 41 are adapted to the locking groove and can slide smoothly in the locking groove.

[0025] The bottom end of the guide section 31 of the slot extends directly to the bottom end of the male connector 3. Therefore, during the insertion and engagement of the male connector 3 and the female connector 4, the locking pin 41 can enter the slot from the bottom end of the guide section 31. When the locking pin 41 reaches the top of the guide section 31, the blade connector 2 is rotated horizontally, and the locking pin 41 enters the locking section 32. At this time, the locking pin 41 engages with the slot, thereby restricting the movement of the blade connector 2 relative to the stirring drive shaft 1 in the vertical direction.

[0026] The implementation principle of the above embodiments is as follows: When installing the blade connector 2, adjust its orientation so that the female connector 4 at the top of the blade connector 2 aligns with the male connector 3 at the bottom of the stirring drive shaft 1. Vertically lift the blade connector 2 so that the two locking pins 41 inside the female connector 4 enter the guide sections 31 of the two slots on the side wall of the male connector 3. Continue lifting the blade connector 2 until the locking pins 41 reach the top of the guide sections 31. Then, rotate the blade connector 2 horizontally, and the locking pins 41 move from the guide sections 31 into the locking section 32. Continue rotating until the locking pins 41 reach the top of the limiting section 33. Then, release or vertically pull down the blade connector 2 so that the locking pins 41 enter the bottom of the limiting section 33. At this point, the locking pins 41 are fully engaged with the slots, and the blade connector 2 can rotate circumferentially under the drive of the stirring drive shaft 1. Under the influence of the weight of the blade connector 2 and the stirring blade itself, the locking pin 41 cannot disengage from the limiting section 33, and the connection between the blade connector 2 and the stirring drive shaft 1 is stable.

[0027] When it is necessary to disassemble the blade connector 2, the operation is reversed. That is, first lift the blade connector 2 so that the locking pin 41 moves from the limiting section 33 into the locking section 32, then rotate the blade connector 2 horizontally so that the locking pin 41 moves from the locking section 32 into the guiding section 31, and then pull down the blade connector 2 to remove it from the stirring drive shaft 1.

[0028] Although preferred embodiments of the present invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including both the preferred embodiments and all changes and modifications falling within the scope of the present invention. Clearly, those skilled in the art can make various alterations and modifications to the present invention without departing from its spirit and scope. Thus, if such modifications and modifications fall within the scope of the claims of the present invention and their equivalents, the present invention also intends to include such modifications and modifications.
