Background

In the filling process of medical soft bags, an operator needs to divide a plurality of stacked medicine soft bags into single soft bags and then transfer the single soft bags to a designated station for subsequent filling process. The large-capacity soft bag needs to be transferred to a designated filling station to realize filling, and the soft bag conveying station and the filling station have discontinuity, namely the soft bag is conveyed to the filling station in place and then needs to be carried to the filling station with assistance, so that a transfer mechanism is needed to ensure the suction and transfer of the soft bag. At present, a large-capacity soft bag is made of two materials of PVC and non-PVC, a non-PVC film is generally made of bag making, filling and sealing integrated equipment, and a plurality of PVC bags are made by first making bags or purchasing finished bags and then filling. PVC bags are easy to be adhered, and manual bag separation and bag feeding are needed. And because the soft bag is easy to deform in the filling process, the opening of the soft bag is difficult to be opposite to a liquid filling pipe of the filling machine, so that the soft bag is often separated and combined with the end part of the liquid filling pipe manually, the combination degree of each soft bag and the end part of the liquid filling pipe is difficult to be kept consistent, and the leakage of liquid medicine in the untight soft bag is easy to cause.

The utility model has the advantages of simple structure, being beneficial to controlling the residual oxygen content of the soft bag, and the like; however, the above patent still has a defect, when the invention is applied to the filling treatment of the soft bag with larger capacity, because the large capacity soft bag stores more liquid medicine, the liquid in the large capacity soft bag is basically concentrated under the soft bag under the action of gravity in the whole filling process, and the soft bag is kept fixed only by the combination between the pipe orifice part and the suspension device, so that the liquid medicine enters the soft bag during filling, larger gravity is generated, and for the suspension conveying of the large capacity soft bag, the larger gravity can damage the critical parts of the soft bag such as the pipe orifice and the like, and the soft bag is incomplete; so that the technical solution is limited.

In view of this, the present invention provides a medical infusion soft bag filling machine to solve the above technical problems.

During operation, the infusion soft bag 13 after liquid filling is moved to the end part of the operation groove far away from the liquid filling host 21 after passing through the liquid filling host 21, at the moment, the part 123 of the first fixed block in contact with the infusion soft bag 13 is moved to the end part of the first conveyor belt 12, the first fixed block 123 in contact is separated at the moment, the fixed hole 15 at the position of the relative gap of the first fixed block 123 is decomposed into a first half hole 151 and a second half hole 152, the surface of the bag body 132 of the infusion soft bag 13 is also separated from the second conveyor belt 16 in contact, the support effect is not exerted, and a part of the infusion soft bag 13 is separated from the first half hole 151 and falls into the collection box 17 under the action of gravity; the other part of the soft infusion bag 13 still attached to the first half-hole 151 moves along with the first belt 122 and is in contact with the extrusion block 111, the side surface of the second fixing block 136 on the soft infusion bag 13 is in contact with the inclined side surface of the extrusion block 111 and is extruded, and a component force far away from the first half-hole 151 can be decomposed in the extrusion force applied to the second fixing block 136, so that the second fixing block 136 drives the soft infusion bag 13 to be separated from the first half-hole 151 and fall into the collection box 17, the labor amount for manually recycling the soft infusion bag 13 is reduced, and the labor intensity of an operator is further reduced.

The specific working process is as follows:

an operator starts the first conveyor belt 12 in the first groove 141 on the two sides of the conveying groove 14, the first belt 122 on the first conveyor belt 12 rotates around the first roller 121 at a slow speed, when the first half hole 151 of the first fixed block 123 on the side surface of the first conveyor belt 12 on the left side is exposed, the infusion tube 131 on the large-capacity infusion soft bag 13 is embedded into the first half hole 151 through a mechanical arm or a manual work, so that the infusion soft bag 13 is combined with the first belt 122, at the moment, the infusion soft bag 13 is kept vertical, and the part, close to the infusion tube 131, in the attaching part 134 on the infusion soft bag 13 is contacted with the inner surface 124 of the second groove on the first fixed block 123; with the rotation of the first belt 122, the first belts 122 on two sides are contacted at the gap part between the transmission grooves 14, the first half holes 151 and the second half holes 152 on the first belts 122 on two sides are combined to form the fixed holes 15, the infusion tube 131 is tightly fixed in the fixed holes 15, and the part, which is contacted with the infusion soft bag 13, on the first fixed blocks 123 on two sides is moved to the gap between the transmission grooves 14, and the distance between the opposite surfaces of the second grooves 124 on the first fixed blocks 123 on two sides is smaller than the thickness of the fitting part 134, so that the part, which is close to the infusion soft bag 13, of the fitting part 134 is tightly contacted with the opposite surfaces of the second grooves 124 on two sides, and is further fixed, and the tight combination state between the first fixed blocks 123 is kept when the infusion soft bag 13 moves in the transmission grooves 14, and the relative movement is avoided; when the infusion soft bag 13 moves to a position right below the infusion gun 22 of the infusion main machine 21, the intelligent control terminal of the infusion main machine 21 controls the first conveyor belt 12 to stop moving, then the movable sliding block 23 drives the infusion gun 22 to move downwards and extend into the opening of the infusion tube 131, the infusion gun 22 is started, and liquid medicine is injected into the liquid storage cavity 133 in the bag body 132; after the liquid medicine is injected, the gravity of the bag body 132 is rapidly increased due to the large volume of the soft infusion bag 13, the pulling force on the infusion tube 131 is rapidly increased, and the part of the infusion tube 131 may be damaged; therefore, the fixing hole 15 is tightly combined with the infusion tube 131 to ensure the fixation of the filled infusion soft bag 13, the part of the attaching part 134 on the bag body 132 close to the top is tightly contacted with the opposite surface of the second groove 124, and the bag body 132 is subjected to upward friction force, so that the gravity increased after a part of the bag body 132 is filled with liquid is offset, the pulling force on the infusion tube 131 is reduced, and the damage of the infusion tube 131 caused by over-tension is avoided; and the part of the outer surface of the fitting part 134, which is in close contact with the opposite surface of the second groove 124, is uniformly provided with a transverse anti-slip groove 135, so that the friction force applied to the fitting part 134 is further increased, and the infusion soft bag 13 after liquid filling is kept stable in the transmission groove 14; after the liquid filling is finished, the soft infusion bag 13 continues to move to the position below the gland device, and the opening part of the infusion tube 131 is combined with the sealing cover under the action of the gland device, so that the soft infusion bag 13 is sealed; finally, the transfusion soft bag 13 after sealing treatment continues to move forward to be recovered; after the infusion tube 131 is embedded into the first half-hole 151, the end part of the infusion tube 131 is vertically pressed downwards, so that the infusion tube 131 moves in the first half-hole 151, and the lower surface of the second fixing block 136 on the outer surface of the infusion tube 131 is in contact with the upper surface of the first fixing block 123, so that the infusion hose is limited, the infusion hose is prevented from falling downwards in the first half-hole 151 and falling, and the workload of operators for recovering the falling infusion hose is increased; the pipe orifice part of each infusion soft bag 13 entering the transmission groove 14 is positioned on the same plane through the limiting function of the second fixing block 136, so that the depth of the infusion gun 22 embedded into each infusion pipe 131 is kept consistent when the infusion gun 22 is combined with the infusion pipe 131, the situation that the infusion gun 22 is embedded into the infusion pipe to be too shallow to cause liquid medicine seepage is avoided, and the filling quality of the infusion soft bags 13 is further ensured; because the second conveyor belt 16 below the conveying groove 14 is obliquely arranged, and the moving speed of the second belt 161 on the second conveyor belt 16 is consistent with that of the first conveyor belt 12, when the soft infusion bag 13 moves into the conveying groove 14, the surface of the bag body 132 of the soft infusion bag 13 is contacted with the oblique surface of the first conveyor belt 12, and the part of the first conveyor belt 12 contacted with the bag body 132 is synchronously moved with the bag body 132; after the infusion soft bag 13 is filled, the bag body 132 expands and is tightly contacted with the surface of the first conveyor belt 12, so that the surface of the bag body 132, which is contacted with the first belt 122, is subjected to upward friction force which is parallel to the surface of the first belt 122 in an inclined manner, the gravity of the bag body 132 is further counteracted, and the tension force applied to the infusion tube 131 is reduced; the conical rubber on the first conveying belt 12 increases the relative friction between the contact surfaces, so that the transfusion soft bag 13 is further ensured to be stable in the moving process; in addition, in the moving process of the infusion soft bag 13, the bag body 132 leans against the surface of the second belt 161 to be limited, so that the infusion soft bag 13 after liquid filling is prevented from shaking left and right in the transportation process, and the fixing of the first fixing block 123 on the infusion soft bag 13 is prevented from being influenced.
