Description

Lever type plasma bag pulling mechanism

Technical Field

The utility model relates to a pharmaceutical equipment field, especially a bag mechanism is dialled to lever plasma bag.

Background

The raw material for producing blood products is frozen plasma (plasma is sealed bags) stored at the temperature of-20 ℃ or below, and the plasma bags are stored, transferred, selected and the like in the common environment and are easily polluted by the external environment, so the outer surfaces of the plasma bags need to be cleaned and disinfected before feeding to remove microorganisms and pyrogens on the outer surfaces of the plasma bags, then the plasma bags are broken open, the plasma in the plasma bags is melted in a plasma melting tank, and then the plasma bags are transferred to the subsequent processes for treatment.

The bag breaking machine is needed to perform operations such as cleaning, disinfection, bag breaking and the like on the plasma bag. The bag pulling mechanism contained in the bag breaking machine is used for horizontally conveying and transferring the frozen plasma bag and is an important component of the bag breaking machine.

The structure of a bag pulling mechanism in a conventional bag breaking machine is shown in fig. 2, and comprises a frame 5, a conveying assembly and a bag pulling assembly. The conveying assembly comprises a driving shaft A, a driven shaft A, a conveying belt 63 and a driving motor A64. The driving shaft A and the driven shaft A are installed at both ends of the frame 5 and arranged in parallel with each other. The conveyer belt 63 is wound between the driving shaft A and the driven shaft A. A drive motor a64 is fixedly mounted on the frame 5 and is associated with the drive shaft a to drive the drive shaft a in rotation. The bag poking assembly comprises a reduction box 71, a drive motor B72 and a bag poking roller 73. The reduction box 71 is fixedly mounted on the frame 5, and is provided with a power input shaft and a power output shaft. The driving motor B72 is fixedly arranged on the frame 5 and is connected with the power output shaft of the reduction box 71. The bag poking roller 73 is connected to the power output shaft of the reduction box 71 and is positioned at the upper end of the rear end part of the conveying belt 63, and a gap for the passing of the blood pulp bag is formed between the bag poking roller and the conveying belt 63.

When dialling bag mechanism during operation, the plasma bag is along the removal after conveyer belt 63 from the past, when the plasma bag removed conveyer belt 63 rear end portion, will contact with 5 borders of frame, 5 borders of frame can hinder the transport of plasma bag to a certain extent, need dial bag roller 73 and assist and stir the plasma bag and move forward to make the complete conveyer belt 63 and the frame 5 that break away from of plasma bag, get into subsequent process and handle.

Because the thickness of each frozen plasma bag has certain deviation, the gap between the bag poking roller and the conveying belt is fixed. For the plasma bag with the thinner thickness, the bag pulling roller is not contacted with the surface of the plasma bag or is contacted with the surface of the plasma bag in a small amount, and for the plasma bag with the thicker thickness, the plasma bag is difficult to pass through the gap, and the effect of assisting the plasma bag to be discharged from the rear end of the conveying belt is difficult to achieve.

Therefore, the reliability and the adaptability of the bag shifting mechanism in the existing bag breaking machine are required to be improved.
