As an embodiment of the present invention, two corresponding sealing plates 35 are provided with a third sliding groove on the side surface on the opposite side; the inside of the third sliding chute is connected with a sealing block 29 in a sliding way; during operation, because two sealing plate 35 in the in-process of motion in opposite directions, can seal the extrusion to infusion bag, the infusion bag that especially can make produces high pressure inside, lead to the infusion bag to be propped brokenly easily, consequently through one of them relative one side sliding connection sealing block 29 in two corresponding sealing plate 35, through the slip of sealing block 29, two sealing plate 35 that can make can't seal completely, consequently, the liquid medicine of infusion bag below can flow upwards, when accomplishing the laminating of two sealing plate 35, sealed block 29 is removed to the rethread, realize sealing plate 35's complete sealing, effectual reduction produces stronger pressure to infusion bag inside because of sealed.
The specific working process is as follows:
when the infusion bag filling machine works, when the infusion bag needs to be filled with liquid medicine, firstly, the soft infusion bag is placed in the filling machine, the liquid filling ports of the infusion bag are required to be correspondingly inserted into the insertion columns 31 of the filling machine respectively, the infusion bag can be positioned on the basis through the insertion columns 31, the insertion columns 31 face the opening direction of the filling machine under the initial condition, then the switch of the filling machine is started, further, the conveying columns 3 of the filling machine rotate to drive the insertion columns 31 to rotate to the position right below the conveying columns 3, at the moment, the liquid filling ports of the infusion bag vertically face the upward direction, then the sliding blocks in the first sliding chute and the second sliding chute slide backwards, further, the sliding blocks can convey the infusion bag to the position right above the limiting groove through the conveying columns 3, the liquid filling port of the infusion bag can be effectively clamped through moving the clamping blocks 33, then, the insertion columns 31 reset, and a new, meanwhile, a piston rod of the cylinder 2 below the top plate is ejected out to drive the movable plate 21 to move downwards, the sliding plate 22 is controlled to move back and forth, the injection head 24 can be moved to a position right above an injection port of an infusion bag and ejected downwards through the telescopic rod 23, the injection head 24 can be inserted into the infusion bag, the infusion bag is firstly inflated through the air inlet pipe to avoid inner wall adhesion of the infusion bag, then quantitative liquid medicine is injected into the infusion bag, meanwhile, redundant gas in the infusion bag is sucked out through the air outlet pipe, then, the position, close to the injection port of the infusion bag, of the infusion bag can be clamped and sealed through the clamping plate by moving the clamping plate, at the moment, the telescopic rod 23 can be upwards recovered to drive the injection head 24 to be pulled out of the injection port of the infusion bag, then, the sliding plate 22 is moved forwards, the telescopic rod, after the sealing is finished, the sealing plate 35 and the clamping block 33 are opened, and the infusion bag falls onto the conveying belt 11, so that the infusion bag can be quickly moved out of the filling machine; the lower edge of the liquid injection head 24 is chamfered, so that a guiding effect can be achieved, the insertion is smoother, the liquid injection head 24 is made of rubber, on one hand, effective sealing can be achieved, and meanwhile, the phenomenon of propping and cracking of an injection port of an infusion bag can be effectively avoided due to the elastic characteristic of the rubber; the annular groove is formed in the outer arc surface of the liquid injection head 24, the telescopic annular air bag 25 is arranged in the annular groove, and the annular air bag 25 is inflated and deflated to realize a sealing effect, so that the liquid injection head 24 is easy to insert and pull; through one of them relative side sliding connection sealing block 29 in two corresponding sealing plates 35, through the slip of sealing block 29, two sealing plates 35 that can make can't seal completely, consequently the liquid medicine of infusion bag below can flow upwards, and when accomplishing the laminating of two sealing plates 35, the rethread removes sealing block 29, realizes sealing plate 35's complete sealing, and effectual reduction produces stronger pressure to infusion bag inside because of sealed.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
