Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical liquid production technology, specifically a closed-loop dust-free feeding device for pharmaceutical liquid production. Background Technology

[0002] The closed-loop dust-free dispensing system for liquid preparation is an advanced piece of equipment used in the production of pharmaceutical solutions. It mainly consists of a feeding port, a dust removal device, a material conveying pipeline, and a mixing container. The entire system is closed, which effectively prevents dust from escaping and can precisely control the amount of material dispensed. In the injection production workshops of some large pharmaceutical companies, this equipment can ensure that no dust is generated during the process of adding drug powder into the liquid preparation container, thus maintaining a clean environment in the workshop.

[0003] Currently, closed-loop dust-free feeding devices for pharmaceutical liquid production use fans to suck in dust and prevent it from falling into the room and affecting the working environment of the staff. However, current dust-free feeding stations require opening the hopper doors and pouring the powder into the feeding station when feeding powder. During the pouring process, some powder will float out and enter the room, resulting in poor dust suppression. Utility Model Content

[0004] The purpose of this invention is to provide a closed-loop dust-free feeding device for pharmaceutical liquid production, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a closed-loop dust-free feeding device for pharmaceutical liquid production, comprising a feeding station body and a dust suppression device. The top of the feeding station body is equipped with a dust suppression device for cleaning floating dust. The interior of the feeding station body is equipped with multiple support rods. The inner wall of the feeding station body away from the feed inlet is equipped with an auxiliary component for supporting bagged raw materials. The outer wall of the dust suppression device is equipped with a shell. The interior of the shell is equipped with a transmission rod for transmission. A pull rope is wound around the outer wall of the transmission rod. The other end of the pull rope is equipped with a hook for assisting in feeding. The outer wall and the top interior of the feeding station body are equipped with a guide component for guiding the pull rope.

[0006] Preferably, an opening is provided on the lower part of the front surface of the housing to provide space for the pull cord to move.

[0007] Preferably, a spring is provided inside the connection between the transmission rod and the outer shell, and the inner ring of the spring is connected to the transmission rod, while the outer ring is connected to the inner wall of the outer shell.

[0008] Preferably, the pull rope is made of nylon.

[0009] Preferably, the auxiliary component includes a connecting plate disposed on the inner wall of the feeding station body, and a support baffle for supporting the bagged dust material is provided on the side of the connecting plate away from the inner wall of the feeding station body.

[0010] Preferably, the surface of the support baffle is uniformly provided with multiple through holes.

[0011] Preferably, the guiding assembly includes a first guide wheel, which is disposed on the outer wall of the feeding station body. The top of the inner part of the feeding station body is provided with a sleeve for cleaning dust from the outer wall of the pull rope. A second guide wheel is disposed at the center of the inner part of the feeding station body.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The sleeve can clean the dust on its outer wall during the rope pulling process, preventing the rope from carrying dust into the feeding station or other areas, further maintaining the cleanliness of the inside and surrounding environment of the device, and avoiding the accumulation of dust on the key components of the device, which would affect the normal operation of the equipment and the quality of the liquid.

[0014] Multiple support rods and support baffles in the auxiliary components work together to provide a stable and reasonable support structure for powder bag filling. The multiple through holes on the surface of the support baffles allow a small amount of scattered dust to fall down for easy collection and treatment without hindering the support function. This support design makes it easy for operators to place the powder bag in the right position and effectively prevents the powder bag from tilting during the subsequent pouring process, ensuring that the material can be accurately put into the liquid preparation process and improving the accuracy of feeding.

[0015] By utilizing the coordinated operation of the transmission rod, pull rope, hook, and guide assembly, the operator can easily pass the hook through the powder bag and pull it upwards to pour the material by simply pulling the pull rope and using the guidance of the first and second guide wheels. The high-strength nylon pull rope has good mechanical properties and can reliably complete the lifting action of the powder bag. The entire operation process is simple and convenient, reducing the labor intensity of manual feeding and improving production efficiency. It is especially suitable for frequent feeding operations in large-scale pharmaceutical liquid production, thereby reducing dust entering the room and causing pollution.

[0016] The outer casing design not only provides stable support for the transmission rod, but the through hole at its bottom and the internal spring structure allow the spring to cleverly store and release energy when the rope pulls the transmission rod, assisting in the rope's winding and unwinding actions. This makes the entire feeding operation smoother and more stable, while also reducing the need for an additional power source and lowering the equipment's energy consumption and operating costs.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a closed-loop dust-free feeding device for pharmaceutical liquid production, such as... Figure 1 As shown, the existing dust-free feeding device includes a feeding station body 1 and a dust suppression device 2. The feeding station body 1 has an inlet and an outlet on its front and bottom, respectively, and a hopper plate is installed at the inlet. The top of the feeding station body 1 is equipped with a dust suppression device 2 for cleaning floating dust, and the dust suppression device 2 is used to clean the dust inside the feeding station body 1.

[0024] In one implementation, such as Figure 2 As shown, multiple support rods 3 are evenly arranged inside the feeding station body 1 and at the top of the discharge port. The support rods 3 are used to support the powder bag. When the multiple support rods 3 are set, gaps are formed on their inner sides, allowing the powdered material to fall into the discharge port through the gaps. The multiple support rods 3 are set horizontally to form a horizontal plane, ensuring that the powder bag is above the discharge port and below the dust suppression device 2 when the powdered material is put in, preventing the powder bag from shifting. An auxiliary component is provided on the inner wall of the feeding station body 1 on the side away from the inlet to support the bagged raw materials.

[0025] like Figure 1and Figure 2 As shown, the dust suppression device 2 has an outer shell 6 on its outer wall. An opening is provided on the lower front surface of the outer shell 6 to provide space for the pull rope 8 to move. After passing through the outer shell 6, the pull rope 8 contacts the first guide wheel 9 on its outer wall. The outer shell 6 supports the transmission rod 7. Inside the outer shell 6 is the transmission rod 7 for transmission. One end of the pull rope 8 is fixedly wound around the outer wall of the transmission rod 7. A spring is installed inside the connection between the transmission rod 7 and the outer shell 6. The inner coil of the spring is connected to the transmission rod 7, and the outer coil is connected to the inner wall of the outer shell 6. During rotation, the transmission rod 7 can retract the inner coil of the spring.

[0026] Furthermore, a pull rope 8 is wound around the outer wall of the transmission rod 7, and a hook 12 for assisting in the feeding operation is provided at the other end of the pull rope 8. The pull rope 8 is made of nylon. When the pull rope 8 is pulled by the first guide wheel 9 and the second guide wheel 11, the powder bag can be pulled upward through the hook 12 to perform the feeding operation. The hook 12 can pass through the powder bag and pull it upward through the pull rope 8. The outer wall and the inner top of the feeding station body 1 are provided with guide components for guiding the pull rope 8. The pull rope 8 can guide the hook 12 to the center position of the feeding station body 1 through the guide components, thereby facilitating the upward pulling of the powder bag for feeding. One end of the pull rope 8 that fixes the hook 12 passes through the guide components and extends into the interior of the feeding station body 1, and is suspended above the support rod 3.

[0027] like Figure 1 and Figure 2 As shown, the guiding assembly includes a first guide wheel 9, which guides the pull rope 8 into the interior of the feeding station body 1. The first guide wheel 9 is located on the outer wall of the feeding station body 1. A second guide wheel 11 is located at the center of the interior of the feeding station body 1. The second guide wheel 11 provides support for the pull rope 8 and provides secondary guidance to one end of the pull rope 8 connected to the hook 12, so that the hook 12 is suspended above the support rod 3.

[0028] Furthermore, in this embodiment, a sleeve 10 for cleaning dust from the outer wall of the pull rope 8 is provided at the top of the inner part of the feeding station body 1. The inner diameter of the sleeve 10 matches the diameter of the pull rope 8. The pull rope 8 is successively attached to the first guide wheel 9 and the second guide wheel 11 and passes through the sleeve 10. After passing through the inside of the sleeve 10, the dust attached to the surface of the pull rope 8 can be cleaned through the cross section of the sleeve 10.

[0029] like Figure 2 As shown, the inner wall of the feeding station body 1 on the side away from the feed inlet is provided with an auxiliary component for supporting the powder bag. The auxiliary component can support the powder bag, thereby facilitating the upward pulling of the powder bag for feeding.

[0030] In a preferred embodiment, the auxiliary component includes a connecting plate 4, which is disposed on the inner wall of the feeding station body 1. The connecting plate 4 is used to provide an installation position for the support baffle 5. The other end of the connecting plate 4 is provided with a support baffle 5 for supporting the powder bag. The support baffle 5 is used to support the powder bag after it is placed inside the feeding station body 1 to prevent it from tilting and to ensure that the surface of the powder bag support baffle 5 is uniformly provided with multiple through holes.

[0031] Working principle: When starting to use the device, the user first opens the hopper plate in the main body 1 of the feeding station, and then puts the powder bag into the inside of the main body 1 and places it on the top of the support rod 3. One side of the powder bag is attached to the outer wall of the support baffle 5, and the powder bag is supported by the outer wall of the support baffle 5.

[0032] The user picks up hook 12 and pulls it downwards. During this pull, the user moves along the outer walls of the second guide wheel 11 and the first guide wheel 9 via the pull rope 8. As the user moves, pulling the rope downwards causes the transmission rod 7 to rotate. Because the mainspring has special elastic deformation characteristics, it initially stores a certain amount of elastic potential energy. When the transmission rod 7 starts to rotate, due to the connection between the inner coil of the mainspring and the transmission rod 7, the inner coil of the mainspring will contract and deform as the transmission rod 7 rotates. Simultaneously, the outer coil of the mainspring is relatively fixed due to its connection with the outer casing 6, thus generating elastic torque inside the mainspring. After pulling hook 12 to the desired position, it is passed through the powder bag to connect hook 12 to the powder bag. The mainspring will then... The elastic restoring force of the body attempts to return to the initial undeformed state, thereby driving the transmission rod 7 to rotate in the opposite direction, converting the stored elastic potential energy into the kinetic energy of the transmission rod 7, causing the pull rope 8 to pull the powder bag upward through the hook 12. When pulled upward, the powder bag is in a vertical state, and the powder material inside the powder bag falls downward through the opening at the bottom of the powder bag to the bottom of the feeding station body 1 for feeding. After the powder material in the powder bag has fallen out, the user opens the hopper plate and removes the powder bag from the outer wall of the hook 12. Then the user releases the hook 12, and the characteristics of the spring drive the transmission rod 7 to rotate and wind the pull rope 8, so that the hook 12 is reset.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
