Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical production line technology, specifically to a continuous filling and sealing production line for infusion soft bags. Background Technology

[0002] Infusion bags are fully closed intravenous infusion products widely used in clinical practice. Currently, common infusion bag production lines mainly include bag-making and filling processes. While the bag-making and filling processes are interconnected, the filling process is fixed, and the infusion bags in the bag-making process pass through the filling stage intermittently via a first conveyor belt. The next infusion bag can only be filled after the previous one is completed. After filling, the infusion bags are further conveyed by the first conveyor belt for sealing. Therefore, the production process is intermittent, making continuous processing difficult and resulting in low production efficiency, which urgently needs improvement. Utility Model Content

[0003] The technical problem solved by this utility model is to provide a continuous filling and sealing production line for infusion soft bags, so as to overcome the shortcomings in the above-mentioned background technology.

[0004] The technical problem solved by this utility model is achieved by the following technical solution:

[0005] A continuous filling and sealing production line for infusion soft bags includes a bag-making section, a filling section, and a capping section. The filling section includes a rotary filling machine, with a first gripper at each filling port. The bag-making section and the filling section are connected by a horizontally rotating first gripper disc, and the filling section and the capping section are connected by a horizontally rotating second gripper disc. Both the first and second gripper discs have multiple second grippers spaced circumferentially. The claws on the first and second grippers are horizontally open and matched to the interface of the infusion soft bag.

[0006] In this invention, a second conveyor belt is provided between the bag-making section and the gripper plate. Multiple third grippers are provided on the second conveyor belt. The claws on the third grippers are all horizontally open and matched with the interface of the infusion soft bag.

[0007] In this invention, the first gripper, the second gripper, and the third gripper are each equipped with an independent cam assembly, and the gripper opens or closes under the drive of the cam assembly.

[0008] In this utility model, the bag making section includes a frame and a first conveyor belt set on the frame. A film feeding mechanism, a forming mechanism, and an interface heat welding mechanism are arranged sequentially along the conveying direction of the first conveyor belt.

[0009] In this utility model, the capping section includes a capping mechanism and a capping mechanism. The capping mechanism and the capping mechanism are connected by a third gripper plate. The capping mechanism is equipped with a heating mechanism and a fourth gripper that matches the third gripper plate.

[0010] In this invention, the capping section is also connected to the bag-out section.

[0011] Beneficial effects: The continuous filling and sealing production line for infusion soft bags described in this utility model solves the problem of mismatch between filling, sealing and bag making capacity in traditional technology. It improves upon traditional technology so that the production and filling of infusion soft bags can be carried out without interruption, thereby realizing continuous processing and production of infusion soft bags. After practical application, it can maximize bag making capacity and greatly improve production efficiency and unit capacity. Attached Figure Description

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0018] See Figures 1-4 As shown.

[0019] The continuous filling and sealing production line for infusion soft bags includes a bag making section 1, a filling section 2, a capping section 4, and a bag exit section 6.

[0020] like Figure 1As shown, the bag-making section 1 includes a frame 11 and a first conveyor belt 12 mounted on the frame 11. Along the conveying direction of the first conveyor belt 12, a film feeding mechanism 13, a forming mechanism 14, and an interface heat welding mechanism 15 are sequentially arranged. The film feeding mechanism 13 pulls the film onto the first conveyor belt 12. The forming mechanism 14 heat-seales and cuts the periphery of the film to form a bag preform. The interface heat welding mechanism 15 connects a rigid interface to the bag preform. The bag preform, after being connected to the interface, is further conveyed in an orderly manner via the first conveyor belt 12.

[0021] The filling section 2 includes a rotary filling machine with multiple filling ports at its bottom, each equipped with a matching first gripper 21. The bag-making section 1 and the filling section 2 are connected by a horizontally rotating first gripper disc 3. The first gripper disc 3 has multiple second grippers 31 spaced circumferentially, and the claws 7 on the second grippers 31 are all laterally open and matched to the interfaces on the infusion bag. Figure 2 As shown, in a preferred embodiment, for further efficient connection, a second conveyor belt 16 is provided between the bag-making section 1 and the first gripper plate 3. Multiple third grippers 161 are provided on the second conveyor belt 16, with the claws 7 on each gripper 161 having transverse openings and matching the infusion bag. The third grippers 161 on the second conveyor belt 16 are used to grip the preform bag with the interface on the first conveyor belt 12, so as to connect it to the first gripper plate 3 more efficiently. In practical applications, the second conveyor belt 16 can be arranged adjacent to the first conveyor belt 12, or it can be connected with the assistance of a short conveyor belt. In this embodiment, since filling does not require interruption, it is extremely efficient. One filling section 2 can simultaneously connect two or more bag-making sections 1, greatly improving production efficiency.

[0022] The filling section 2 and the capping section 4 are connected by a horizontally rotating second gripper disc 9. In practical applications, multiple adjacent second gripper discs 9 can be used to meet actual production needs. The second gripper disc 9 also has multiple second grippers 31 distributed circumferentially. The claws 7 on the second grippers 31 are all laterally open and matched with the interfaces of the preforms on the filling section 2 and the capping section 4. The capping section 4 includes a capping mechanism 5 and a capping mechanism. The capping mechanism 5 and the capping mechanism are connected by a third gripper disc 10. The capping mechanism is equipped with a heating mechanism 41 for heating the interface of the preform to ensure a sealed connection between the cap and the interface. The capping mechanism is equipped with a fourth gripper 42 that matches the third gripper disc 10. The claws 7 on the fourth gripper 42 are laterally open and matched with the capping mechanism 5.

[0023] The pawls 7 on the first gripper 21, second gripper 31, third gripper 161, and fourth gripper 42 are each equipped with independent cam assemblies 8, such as... Figure 3As shown, the chuck 7 opens or closes under the drive of the cam assembly 8, and the chuck 7 clamps the rigid interface or cap of the preform, such as... Figure 4 As shown, the upper and lower parts of the rigid interface of the preform can be respectively connected to the claws 7 on the two grippers, thereby achieving efficient and continuous connection. Furthermore, in actual production, regardless of the bag's size, shape, or structure, as long as the interface is identical, the production line described in this invention can be used, making its practical application extremely wide.

[0024] The capping section 4 is connected to the bag exit section 6, so that the filled and capped bags can be automatically transported for subsequent packaging.
