[0038] The use method of the utility model is as follows:
[0039] When the components of the disposable infusion set 11 are assembled by the infusion set assembly equipment, the disposable infusion set 11 is conveyed to the front feeding mechanism 5 and the rear feeding mechanism 6, and then the front feeding mechanism 5 and the rear feeding mechanism 6 can clamp the disposable infusion set 11. At this time, the second lifting mechanism 503 drives the third clamping jaw 507 on the third pneumatic finger 506 to move downward to clamp the drip bottle 1101 of the disposable infusion set 11, and the third lifting mechanism 607 drives the fourth clamping jaw 616 on the fourth pneumatic finger 615 to move downward to clamp the needle seat 1102 of the disposable infusion set 11. When the clamping is completed, the second lifting mechanism 503 drives the third clamping jaw 507 to move upward, and the third lifting mechanism 607 drives the fourth clamping jaw 616 to move upward, so that the disposable infusion set 11 is separated from the conveying device. Since the third pneumatic finger 506 is arranged on the slider of the first multi-slider linear module 505, and the fourth pneumatic finger 615 is arranged on the slider of the second multi-slider linear module 609, as long as the first multi-slider linear module 505 operates, the distance between the adjacent third pneumatic fingers 506 can be adjusted by the movement of the sliders. The second multi-slider linear module 609 and the first multi-slider linear module 505 both use the existing multi-slider linear module, and the distance between the fourth pneumatic fingers 615 can be adjusted by the movement of the sliders, so as to effectively adjust the distance between the adjacent disposable infusion sets during batch winding of the disposable infusion set, and effectively adapt to the position distribution of the winding motor 405.
[0040] When the front feeding mechanism 5 needs to move forward, the second motor 804 can be started. At this time, the motor shaft of the second motor 804 drives the second screw 805 to rotate. The second moving plate 808 is provided with a second screw hole matched with the second screw 805, and the second sliding block 810 on the lower surface of the second moving plate 808 is matched with the second guide rail 807. Therefore, when the second screw 805 rotates, the second moving plate 808 can convert the rotating force into the force for moving forward. At this time, the second moving plate 808 can drive the front feeding seat plate 501 to move forward through the second traction plate 811, so as to realize the forward movement of the third clamping jaw 507.
[0041] When the third clamping jaw 507 clamps the drip bottle 1101 of the disposable infusion device 11 and moves forward to the top of the first pneumatic finger 410, the forward movement is stopped, and then the third clamping jaw 507 moves downward under the action of the second lifting mechanism 503. When the third clamping jaw 507 moves downward, the fourth clamping jaw 616 moves downward synchronously under the action of the third lifting mechanism 607, so as to realize the overall downward movement of the disposable infusion device. After the third clamping jaw 507 moves downward by a certain stroke, the drip bottle 1101 can be partially placed between the first clamping jaws 411 on the left and right sides of the first pneumatic finger 410. At this time, the first pneumatic finger 410 is started, the first clamping jaws 411 on the left and right sides are close to each other to clamp the drip bottle 1101, the third clamping jaw 507 releases the drip bottle 1101 under the action of the third pneumatic finger 506, and the transfer of the drip bottle 1101 is completed. At the same time, the third clamping jaw 507 moves backward by a certain stroke and clamps again. At this time, the hose 1103 of the disposable infusion device 11 is in the gap between the third clamping jaws 507 on the left and right sides, and the hose 1103 can move freely in the gap. The gap between the third clamping jaws 507 on the left and right sides is smaller than the width of the flow regulator 1104 of the disposable infusion device 11, so when the third clamping jaw 507 moves backward, the flow regulator 1104 can be pushed backward by the rear sidewall of the third clamping jaw 507, effectively changing the position of the flow regulator 1104 on the hose 1103, thereby effectively changing the distance between the flow regulator 1104 and the drip bottle 1101. As the distance between the two changes, the flow regulator 1104 can effectively avoid colliding with the drip bottle 1101 after the hose 1103 is wound. When the hose 1103 of the disposable infusion device 11 is wound into a circle, the positions of the flow regulator 1104 and the drip bottle 1101 can be effectively staggered, and no collision occurs. When the position adjustment of the flow regulator 1104 is completed, the third clamping jaw 507 releases and moves upward to reset. Then the third clamping jaw 507 moves upward to reset on the second lifting mechanism 503. At this time, the fourth clamping jaw 616 always clamps the hose of the disposable infusion device.
[0042] When the first clamping jaw 411 clamps the drip bottle of the disposable infusion set and the fourth clamping jaw 616 clamps the hose of the disposable infusion set, the winding work of the disposable infusion set can be started, and before the winding work starts, the third lifting mechanism 607 drives the fourth clamping jaw 616 to move upward by a certain stroke, so that the disposable infusion set is in a state of being inclined with the front end downward. This state is beneficial to the winding work of the disposable infusion set. Since the drip bottle of the disposable infusion set is clamped and fixed by the first clamping jaw 411, when the winding motor 405 operates, the rotating table 406 rotates, and the supporting seat 408 rotates synchronously with the first clamping jaw 411. At this time, the first clamping jaw 411 is clamped and rotated by the drip bottle, and the hose of the disposable infusion set is pulled forward and wound around the outer ring of the winding rod 409. After the disposable infusion set is wound around the outer ring for the first time, the third lifting mechanism 607 drives the fourth clamping jaw 616 to move upward by a certain stroke again. After the disposable infusion set is wound around the outer ring again, the fourth clamping jaw 616 moves upward by a certain stroke again, so that the hose of the disposable infusion set always maintains an inclined state during the winding process, thereby forming a stacked winding effect, rather than being wound around the outer ring all the time, which effectively avoids the collision of various components of the disposable infusion set.
[0043] When the disposable infusion set is pulled forward for winding, the fourth clamping jaw 616 is always clamped on the needle seat 1102 of the disposable infusion set 11. At this time, the presence of the spring 619 ensures that the disposable infusion set hose can be stably forwarded. When the hose of the disposable infusion set is pulled forward, the fourth clamping jaw 616 is synchronously pulled forward. At this time, the guide rod 617 moves stably forward along the track of the inner wall of the guide sleeve 613, and the spring 619 between the rear end face of the guide sleeve 613 and the front end face of the limiting head 618 is compressed and generates a spring force. This spring force can form a force for pulling the disposable infusion set backward, so as to ensure that the disposable infusion set is pulled into a straight line when being wound, facilitate the opening of the winding work, and avoid the situation that the disposable infusion set is loose and difficult to wind.
[0044] With the winding of the disposable infusion set around the winding rod 409 on the front and rear sides, the length of the disposable infusion set to be wound becomes shorter and shorter. At this time, the rear feeding mechanism 6 drives the fourth clamping jaw 616 to move forward to adapt to the change in length. When the fourth clamping jaw 616 needs to move forward, the displacement motor 902 can be started. At this time, the motor shaft of the displacement motor 902 drives the driving synchronous wheel 903 to rotate, and the driving synchronous wheel 903 and the driven synchronous wheel 906 are connected through the synchronous belt 907. When the driving synchronous wheel 903 rotates, the synchronous belt 907 rotates and conveys. Since the synchronous belt 907 is matched with the tooth plate 603, when the synchronous belt 907 rotates and conveys, the rear feeding seat plate 601 moves under the action of the tooth plate 603, and finally the fourth clamping jaw moves forward.
[0045] When the winding work is completed, the fourth clamping jaw 616 is loosened under the action of the fourth pneumatic finger 615, the first clamping jaw 411 is loosened under the action of the first pneumatic finger 410, and then the second clamping jaw 308 is lowered by the first lifting mechanism 303, so that the second clamping jaw 308 just passes through the gap between the winding rods 409 on the left and right sides to clamp the wound disposable infusion set, since the positions of the second pneumatic fingers 307 on the front and back sides are just corresponding to the front and back ends of the wound disposable infusion set, therefore the second clamping jaws 308 on the second pneumatic fingers 307 on the front and back sides just clamp the wound disposable infusion set at the same time, so as to avoid the wound disposable infusion set from being scattered, and when the wound disposable infusion set is clamped, it can be moved upward by the first lifting mechanism 303, and after being moved to the actual required height, it can be moved forward to the disposable infusion set packaging device for the final packaging work.
[0046] When the wound disposable infusion set needs to be moved forward, the first motor 704 can be started, at this time, the motor shaft of the first motor 704 drives the first lead screw 705 to rotate, the first moving plate 708 is provided with a first screw hole matched with the first lead screw 705, and the lower surface of the first moving plate 708 is provided with a first sliding block 710 matched with the first guide rail 707, therefore when the first lead screw 705 rotates, the first moving plate 708 can convert the rotating force into the force for moving forward, when the first moving plate 708 moves forward, the first moving plate 708 can drive the clamping seat plate 301 to move forward through the first traction plate 711, so that the second clamping jaw 308 moves to the disposable infusion set packaging device with the wound disposable infusion set.
[0047] As can be seen from the above, the disposable infusion set is first clamped by the first clamping jaw 411, and then the soft tube of the disposable infusion set is pulled by the rear feeding mechanism, every time the winding mechanism 4 winds the disposable infusion set once, the rear feeding mechanism 6 drives the soft tube of the disposable infusion set to move upward by a certain stroke, so that the disposable infusion set is always in a state of downward inclination at the front when being wound, and winding in this state can ensure that the disposable infusion set is stacked and wound, effectively avoiding the situation that the components collide with each other when the disposable infusion set is wound in the same plane, and effectively avoiding the situation that the soft tube slips and the disposable infusion set is scattered after being wound in a flat state.
[0048] The rear side of the lower surface of the upper seat plate 403 is provided with a fixing seat 412, the lower surface of the fixing seat 412 is provided with a first cylinder mounting plate 413, the upper surface of the rear end of the first cylinder mounting plate 413 is provided with a first cylinder 414 matched therewith, the upper end of the piston rod of the first cylinder 414 is provided with a supporting plate 415 higher than the upper seat plate 403, the supporting plate 415 can hold the hose upward when the disposable infusion device is rolled, further ensuring the stability during rolling, and the presence of the first cylinder 414 can effectively adjust the height of the supporting plate.
[0049] The first double sliding block cylinder 407 and the second double sliding block cylinder 305 are both existing double sliding block cylinders, the first double sliding block cylinder 407 can effectively adjust the distance between the front and rear rolling rods 409 through the distance between the two sliding blocks thereof, thereby effectively adjusting the volume of the disposable infusion device after rolling, and the second double sliding block cylinder 305 can effectively adjust the distance between the front and rear second clamping jaws 308 through the distance between the two sliding blocks thereof, thereby effectively adapting to the position change of the rolling rod 409.
[0050] The first lifting mechanism 303, the second lifting mechanism 503 and the third lifting mechanism 607 can all adopt existing lifting mechanisms as long as they can realize the lifting function, the simplest lifting mechanism is a cylinder, which can directly control the lifting through the extension and retraction of the piston rod of the cylinder, or a new structure can be adopted, such as a speed reducer mounting seat 1001, the speed reducer mounting seat 1001 is provided with a lifting opening 1002, the lifting opening 1002 has a lifting column 1003, the speed reducer mounting seat 1001 is provided with a speed reducer 1004 matched therewith, the output shaft end of the speed reducer 1004 penetrates into the lifting opening 1002 and is provided with a gear 1005, the lifting column 1003 is provided with a rack 1006 engaged with the gear 1005, at the same time, guide rails 1007 can be arranged on the sidewalls of the lifting column 1003, the lifting opening 1002 is provided with guide sliding blocks 1008 matched with the guide rails 1007, and the material clamping seat plate 301, the front material feeding seat plate 501 and the rear material feeding seat plate 601 can all be arranged at the lower end of the lifting column 1003, when the speed reducer 1004 is started, the gear 1005 rotates, the rack 1006 engaged with the gear 1005 makes the lifting column realize lifting under the guidance of the guide rails 1007, thereby realizing the lifting of the material clamping seat plate 301, the front material feeding seat plate 501 and the rear material feeding seat plate 601.
