Description

TECHNICAL FIELD

[0001] The present application relates to the field of medical devices, in particular to a full-automatic assembling equipment for infusion bags in disposable bag-type infusion devices. BACKGROUND

[0002] The disposable bag-type infusion device is widely used in the medical industry, which is generally composed of a bottle plug puncture device, a puncture device protective sleeve, an air filter, an infusion bag, a drip chamber, a flow regulator, a liquid filter, an intravenous infusion needle, etc. The infusion bag has a handle (or a hanging structure) connected to one end of the infusion bag. A short catheter and a long catheter are connected to the end of the infusion bag with the handle. The long catheter is used for connecting the upper infusion tube and the bottle plug puncture device, and is used for inputting liquid. The short catheter is used for connecting the air filter. A long catheter is connected to the other end of the infusion bag and is connected to the drip chamber, which is used for outputting liquid. In the prior art, manual assembly is mostly used, which has low work efficiency and high labor intensity. CN2021227858806 discloses a rapid assembling device for an intravenous infusion bag. Although this device can replace manual work to achieve automatic assembly, the work efficiency is still not high due to the design of the structure, such as the bag body which needs to be cut in advance and then layered into the bag body storage mechanism and lifted one by one by the lifting mechanism. The catheter feeding mechanism and the pipe lifting feeding mechanism use a vertical pushing method to push the catheters into the bag body one by one. Moreover, the catheter at the other end of the bag body needs to be connected in another process, and the scale on the bag body also needs to be transferred to another device for processing. SUMMARY

Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0028] In this article, terms related to connection relationships, such as "fixed connection" and "connection," are used in a conventional manner, such as bolted connection or welding. Furthermore, structures described as "lifting" utilize conventional lifting methods, such as lifting cylinders.

[0029] like Figures 1-9The full-automatic infusion bag assembling equipment of the present application comprises a bag body feeding mechanism 2, a printing mechanism 3, a first catheter welding mechanism 4, a second catheter welding mechanism 5, a hanger pipe welding mechanism 6, and a conveying mechanism 1.

The bag body blank roll is fed by the bag body feeding mechanism 2 and then enters the conveying mechanism 1 to be cut into individual bag bodies with both ends open. Then, under the action of the conveying mechanism 1, the bag bodies are printed with scales by the printing mechanism 3 and then sequentially reach between the first catheter welding mechanism 4 and the second catheter welding mechanism 5 and on one side of the hanger pipe welding mechanism 6. The insertion and welding of the long catheter at one end of the bag body are realized at the first catheter welding mechanism 4, the insertion and welding of the long catheter and the short catheter at the other end of the bag body are realized at the second catheter welding mechanism 5, and the bending, insertion, and welding of the hanger pipe into the bag body are realized at the hanger pipe welding mechanism 6. The specific structures of the mechanisms are as follows:

[0030] The conveying mechanism 1 comprises a conveying belt 1.1 and a plurality of lifting press plates 1.2 arranged at equal intervals on the conveying belt 1.1. The lifting press plates 1.2 can also be arranged at equal intervals in multiple areas of the conveying belt. Each lifting press plate 1.2 mainly comprises a press plate and one or more lifting cylinders. The piston rod of the lifting cylinder vertically extends upward and is fixedly connected to the press plate at the free end of the piston rod. The piston rod of the lifting cylinder needs to pass through the upper and lower surfaces of the conveying belt, and the connection point between the lifting cylinder and the press plate is located on the central axis in the width direction of the press plate, so that one press plate can press one end of two bag bodies. A bag body placement area 1.3 is formed between each two adjacent lifting press plates 1.2, and the bag body placement area 1.3 and the bag body passing area 2.6 in the bag body feeding mechanism 2 one-to-one correspond in terms of arrangement position and number.

The length of the lifting press plate 1.2 is shorter than the width of the conveying belt 1.1, and the two ends of the lifting press plate 1.2 in the length direction and the two sides of the conveying belt 1.1 in the width direction are both spaced apart.

The partition wheel rod 2.3 is formed by coaxially fixing more than one wheel pair 2.31 on a rod. Each wheel pair 2.31 forms a bag body passing area 2.6. One winding wheel 2.1 is matched with one tension wheel 2.2 and one bag body passing area 2.6. The lifting cutting knife 2.4 mainly comprises at least two lifting cylinders and a cutting knife fixed on the ends of the vertically downward extending piston rods of the two lifting cylinders.

The sliding block 2.51 is embedded in the bottom of the support frame 2.7 and slides in the width direction of the conveying mechanism 1. The maximum position of the sliding block 2.51 sliding away from the lifting cutting knife 2.4 is located directly above the corresponding side of the conveying mechanism 1. The cross rod 2.52 is fixed on the bottom of the sliding block 2.51. The automatic lifting column 2.53 (a lifting cylinder in the prior art) is fixedly connected to the bottom of one end of the cross rod 2.52. The negative pressure suction disc 2.54 is fixed to the bottom of the vertically downward extending free end of the automatic lifting column 2.53.

[0032] During feeding, the lifting pressing plate 1.2 is raised, the one end of the bag body blank roll is placed between the two lifting pressing plates 1.2 of the conveying belt, then the lifting pressing plate 1.2 is pressed down to press the two sides of the bag body blank roll / bag body, and then the lifting cutting knife is lowered to cut the independent bag body from the bag body blank roll. By using such a bag body feeding mechanism, continuous feeding can be realized without the need for prior cutting of the bag body.

When the cut bag body is conveyed to below the printing frame by the conveying belt and the conveying is paused, the sliding ink box 3.3 slides to below the lifting printing plate 3.2, the lifting printing plate 3.2 is lowered to dip the printing plate in ink, the lifting printing plate 3.2 is raised, then the sliding ink box 3.3 returns, and the lifting printing plate 3.2 is lowered to print the scale and scale value on the surface of the bag body.

Under the action of the servo motor, the second lifting pneumatic finger rotates to be longitudinally arranged with the third lifting pneumatic finger, realizes the bending of the pipe, and then slides to the conveying mechanism to realize the connection of the pipe and the side surface of the bag. Then the second lifting hot melting block is lowered to realize the welding of the pipe and the bag.
