One-piece mouth tube non-pvc film automatic bag filling and sealing machine

Abstract

The invention discloses an integral oral tube non-PVC membrane full-automatic bag-making filling and sealing machine. The integral oral tube non-PVC membrane full-automatic bag-making filling and sealing machine comprises a machine body, a membrane supplying mechanism, an oral tube supplying mechanism, a bag maker, a first annular conveying component, a filling and sealing machine, a second annular conveying component, a bag body transferring mechanism and a bag outputting mechanism, wherein the bag maker is used for making membrane materials and integral oral tubes which are conveyed to the bag maker into flexible bags which are partial to one side of each oral tube and are provided with preserved openings; the first annular conveying component is arranged on the bag maker in a matched mode, and is provided with an oral tube fixture; the filling position and the sealing position of the filling and sealing machine correspond to preserved openings of the flexible bags; the second annular conveying component is arranged on the filling and sealing machine in a matched mode, and is provided with a bag body fixture; the bag body transferring mechanism is arranged between the first annular conveying component and the second annular conveying component. An integral oral tube is adopted for the bag-making filling and sealing machine, and the bag-making filling and sealing machine is used for filling and sealing from the preserved openings partial to one side of the oral tube without heating the oral tube and a seal cap at high temperature; solid particles can be effectively prevented; the quality of liquid conveying flexible bags can be improved; the clinical hazard can be reduced; meanwhile, the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of pharmaceutical packaging machinery, in particular to a non-PVC film bag-making filling-sealing machine integrating bag-making and filling-sealing functions, which is suitable for fully automatic mass production of infusion soft bags by pharmaceutical enterprises. Background technique [0002] With the general application of infusion therapy, the infusion method has gone through the development process from open, semi-open to fully closed, and the infusion set has changed from the initial glass bottle, to polyvinyl chloride (PVC) soft bag, to polyvinyl chloride (PVC) soft bag, to poly Propylene, polyethylene (PP / PE) hard plastic bottles, until now the world's most advanced non-PVC composite film soft bags that are fully compliant with environmental protection. [0003] The existing non-PVC film infusion soft bag automatic bag making and filling machine is only suitable for the production of conventional in...

AI Technical Summary

Problems solved by technology

[0007] First, in order to fill from the tail, after the soft bag is formed, it needs to enter the second circular conveying assembly with the mouth tube facing down, so that the filling port at the tail faces up, which is convenient for the filling machine to fill. After hanging upside down, the mouth tube faces down, and the positioning on the fixture of the circular transfer assembly cannot be performed through the mouth tube. Therefore, two positioning holes need to be pre-processed at the tail of the bag body. In order to process the positioning holes, a punching mechanism needs to be added before the trimming and tearing mechanism , which not only increases the equipment cost, but also causes the mechanism to be too complicated

[0008] Second, when using the punching mechanism to process the positioning hole at the tail of the bag, debris is likely to be generated, and there is a risk of mixing the liquid medicine, resulting in a reduction in medical safety. Moreover, due to the existence of the positioning hole, the size of the welding edge at the tail of the soft bag is relatively small. Large, it will take up too much drug-filling space of the soft bag

[0009] Third, the positioning hole at the end of the soft bag only functions during the production process, and has no other purpose in the use of the soft bag. Once the soft bag is processed, it will be a redundant part, and it will affect the overall shape of the soft bag. The infusion hanging hole at the end of the bag is confused

[0010] Fourth, the form of upside-down filling requires the bag body transfer mechanism to fix one end of the mouth tube and one end of the bag tail at the same time when transferring the bag body. Only in this way can the soft bag be adjusted from the horizontal state to the upside-down state and enter smoothly. The second ring transfer assembly requires an interface positioning device and a bag tail positioning device to be installed at both ends of the flipping fixture of the bag body transfer mechanism, resulting in a complex structure of the bag body transfer mechanism, and difficulty in debugging and maintenance

[0011] Fifth, the clamp on the circular transmission assembly penetrates the positioning pin into the positioning hole to hang the soft bag, the action of the clamp is not flexible enough, and the function has great limitations, and the clamp and the guide rail are connected by the cooperation of the V-shaped groove and the roller. The operation is not stable enough and reliable
