Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical equipment technology, specifically a novel multi-bag continuous bag filling device. Background Technology

[0002] In the current pharmaceutical filling industry, the filling process for bagged pharmaceutical solutions is a crucial step. Traditional filling methods mainly include filling single bags and filling multiple bags simultaneously. The filling process typically involves several steps: First, the bag is clamped and then the bag opening is opened. Next, the bag is transferred to the next process, where a flaring device is used to flare the bag opening. Finally, the bag is transferred to the next process for filling. However, this traditional filling method has some problems.

[0003] First, the filling process is quite cumbersome due to the multiple steps involved, making it prone to various problems during transport, such as bag damage and liquid leakage. This not only affects production efficiency but can also lead to product quality issues. Second, in traditional filling methods, a single clamping mechanism is typically used for opening and flaring the bag opening. This clamping mechanism can easily cause the bag opening to shorten during opening and flaring, resulting in friction between the outer surface of the filling bag and the clamping mechanism. This friction can not only cause difficulties in opening and flaring but also scratches on the bag surface, affecting product appearance and packaging quality.

[0004] Furthermore, traditional filling methods often focus only on widening the bag opening during the flaring process, neglecting the space inside the bag. This may result in the bag's interior not being fully opened, thus affecting filling speed and volume. To address these issues, the industry urgently needs a new type of multi-bag continuous filling device to improve production efficiency, reduce production costs, and simultaneously ensure product quality. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a novel multi-bag continuous filling device, which solves the problems of cumbersome processes and difficulties in opening and widening the opening of existing medicines.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: a novel multi-bag continuous bag filling device, including a workbench, on which a conveyor belt and a filling assembly are provided, the filling assembly including a clamping unit arranged along the conveying direction of the conveyor belt and multiple filling units located inside the clamping unit;

[0008] The filling unit includes an upper positioning platform, a filling tube is provided inside the upper positioning platform, and an air blowing pipe is provided on one side of the filling tube; a flaring head is provided at the bottom of the filling tube, a filling nozzle is provided at the bottom end of the flaring head, and an air jet nozzle communicating with the air blowing pipe is provided circumferentially on the outer wall of the flaring head.

[0009] Preferably, the nozzle includes a cone with a bottom surface that is parallelogram-shaped or triangular, and the filling nozzle is located at the apex of the cone.

[0010] Preferably, each of the two retainers is provided with an electric telescopic rod, the output end of which is provided with an air suction pipe, and the air suction pipe is provided with a plurality of suction cups.

[0011] Preferably, the suction tubes located on the two retainers are arranged opposite each other.

[0012] Preferably, each of the opposite surfaces of the clamping platform is provided with a buffer cylinder, and the output end of the buffer cylinder is provided with a head.

[0013] Preferably, the front of the end is provided with a groove, and a clamping head is slidably connected in the groove via a guide rail. A guide rod penetrating the clamping head is provided on the side wall of the groove, and a spring is sleeved on the part of the guide rod located between the clamping head and the side wall of the groove.

[0014] Preferably, the guide rod is arranged along the direction of the guide rail.

[0016] The beneficial effects of this utility model are as follows: By using the novel multi-bag continuous filling device provided by this utility model, compared with the prior art, this device uses a clamping unit to clamp the filling bag and directly uses the cooperation of suction cups and electric telescopic rods to open it, eliminating multiple transfer steps in the traditional method. Furthermore, during the opening and flaring stages, the clamping head moves horizontally on the guide rail in accordance with the opening amount of the filling bag, effectively preventing the bag mouth from detaching from the clamping head or causing scratches on the bag mouth surface. The dual flaring method using a flaring head and an air jet nozzle fully opens both the bag mouth and the inside of the bag. Because the bag mouth and the inside space are fully expanded, the filling speed is significantly improved, thereby increasing overall production efficiency. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present invention 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 invention, and not all embodiments. Various changes can be made to the implementation scheme as long as the effects of the present invention can be achieved.

[0026] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0027] Reference Figure 1-6 This embodiment describes a novel multi-bag continuous filling device. The filling device includes a workbench 1, on which a conveyor belt and filling components are mounted.

[0028] In this embodiment, the filling assembly includes a clamping unit arranged along the conveyor belt conveying direction and multiple filling units located inside the clamping unit. The clamping unit is mainly used for opening and clamping the multi-bag filling bags during filling, ensuring that the filling bags do not shift. The filling units are mainly used for widening and filling the multi-bag filling bags, completing multiple steps in one operation.

[0029] Specifically, the clamping unit in this embodiment includes a bidirectional cylinder 2, which is fixed to the workbench 1 by a beam arm. The two output ends of the bidirectional cylinder 2 are equipped with retainers 3, which are arranged along the conveying direction of the conveyor belt and located on both sides of the multi-bag filling bag. Clamping platforms 4 are arranged opposite each other on the inner sides of the two retainers 3. When the bidirectional cylinder 2 retracts, it drives the retainers 3 on both sides to move, clamping and fixing the two ends of the filling bag through the clamping platforms 4.

[0030] Furthermore, each of the opposing clamping platforms 4 is provided with a buffer cylinder 10 on its opposing surface, and the output end of the buffer cylinder 10 is provided with a head 11. When clamping the filling bag, the buffer cylinder 10 can reduce the impact force when the two opposing heads 11 come into contact, preventing damage to the filling bag. The front of the head 11 is provided with a groove, and a clamping head 16 is slidably connected in the groove through a guide rail 12. The clamping head 16 protrudes from the groove and contacts the filling bag. A guide rod 14 is provided on the side wall of the groove, penetrating the clamping head 16. The guide rod 14 is arranged along the direction of the guide rail 12. A spring 13 is sleeved on the part of the guide rod 14 located between the clamping head 16 and the side wall of the groove.

[0031] When the filling unit flares and fills multi-bag filling bags, the bag opening will be opened, and the length of the bag opening will be shortened (e.g., Figure 6 As shown, the two opposing clamping heads 16 clamp the filling bag. When the bag opening shortens, the clamping heads 16 move laterally on the guide rail 12 to prevent damage to the bag opening caused by hard friction with the clamping heads 16 when the bag opening shrinks. After the clamping table 4 is released, the clamping heads 16 return to their original position under the pull force of the spring 13.

[0032] In a preferred embodiment, a friction pad 15 is provided on the outer wall surface of the clamping head 16 to increase the friction between the clamping head 16 and the outer wall surface of the bag opening.

[0033] In another preferred embodiment, each of the two retainers 3 is equipped with an electric telescopic rod 5. The output end of the electric telescopic rod 5 is equipped with a suction pipe 6, which is connected to a vacuum pump. Several suction cups 7, which are vacuum suction cups, are mounted on the suction pipe 6. When the clamping head 16 clamps onto the outer wall of the filling bag, the suction cups 7 simultaneously adhere to the outer wall of the filling bag. Then, the electric telescopic rod 5 retracts, opening the filling bag. At this time, the opening of the filling bag also experiences a certain amount of displacement, and the clamping head 16 moves along the guide rail 12 in accordance with the opening amount of the filling bag.

[0034] Furthermore, the suction pipes 6 located on the two retainers 3 are arranged opposite each other to ensure that the opening of the filling bag is neat and symmetrical when it is opened, which facilitates the insertion of the nozzle 18.

[0035] The filling unit in this embodiment includes an upper positioning platform 8, which is fixed on the workbench 1. A filling tube 9 is provided inside the upper positioning platform 8. The filling tube 9 is a filling tube in the prior art, which moves up and down with the filling equipment. This part of the technology is prior art and will not be described in detail here. An air blowing pipe 17 is provided on one side of the filling tube 9, and the air blowing pipe 17 is connected to a gas generating device. A flared nozzle 18 is provided at the bottom of the filling tube 9, and a filling nozzle 20 is provided at the bottom end of the flared nozzle 18. An air jet nozzle 19 communicating with the air blowing pipe 17 is provided circumferentially on the outer wall of the flared nozzle 18.

[0036] Furthermore, the nozzle 18 includes a cone with a bottom surface that is parallelogram-shaped or triangular, and the filling nozzle 20 is located at the apex of the cone.

[0037] As the filling tube 9 descends, the nozzle 18 first contacts the open opening of the filling bag and extends into the bag along the opening. Under the action of the cone, the bag opening assembly opens. Gas from the blowing tube 17 is ejected from the nozzle 19 around the nozzle 18 and into the filling bag, causing the inside of the filling bag to be blown open by the gas. At this time, the liquid medicine in the filling tube 9 flows out from the filling nozzle 20 and into the inside of the filling bag.

[0038] After filling is completed, the filling tube 9 rises, causing the nozzle 18 to detach from the filling bag. The suction tube 6 closes, causing the suction cup 7 to lose suction. The bidirectional cylinder 2 pushes forward, causing the retainer 3 to move to both sides, moving the clamping platform 4 away from the filling bag. The conveyor belt continues to transport the filled bag to the next process.

[0039] 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.
