Description

Technical Field

[0001] The utility model relates to an infusion set sticker tape device. Background Art

[0002] An infusion set is a disposable infusion set, a common medical consumable. It's sterile and creates a pathway between the vein and the medication, allowing for intravenous infusion. It typically consists of eight connected components: an IV needle or hypodermic needle, a needle cap, an infusion hose, a medication filter, a flow regulator, a drip pot, a bottle puncture device, and an air filter. Some infusion sets also include an injection device and a dosing port.

[0003] The assembly of the various parts of the disposable infusion set is completed by the disposable infusion set assembly equipment. After the various parts of the disposable infusion set are assembled, the disposable infusion set will be coiled into a ring structure to facilitate the later placement and transportation of the disposable infusion set. In order to prevent the disposable infusion set from becoming scattered after being coiled into a ring structure, it is necessary to stick paper tape on the ring structure to tighten the ring structure. The tape sticking work is generally done by staff using manual tape sticking. Although the staff maintains high work efficiency in a short period of time, once the working time is too long, the staff will feel tired and the speed of tape sticking will slow down, resulting in a rapid decrease in work efficiency. In addition, the manual tape sticking method is difficult to ensure that the quality of tape sticking is consistent each time. At the same time, during the tape sticking process, if the staff makes a mistake, the disposable infusion set originally coiled into a ring structure will become scattered. If the tape sticking work is performed after manual coiling, the quality of the tape sticking will be further affected. Summary of the Invention

[0036] The method of using the utility model is as follows:

[0037] The unwinding wheel 7 is used for the early stage of winding up the paper tape, and at the same time, it releases the originally wound paper tape 26 little by little in the later stage, so as to realize uninterrupted pasting tape action. The paper tape 26 wound up by the unwinding wheel 7 adopts a paper tape with an adhesive layer on one side. The adhesive layer of this paper tape 26 has great adhesive force when it is folded in half and pasted to each other. When it contacts the wall of other components, the adhesive force is extremely small and will not affect the normal transportation of the paper tape 26.

[0038] When the paper tape 26 is normally conveyed, the first cylinder 14 and the fourth cylinder 503 can be started first. When the first cylinder 14 is started, the piston rod of the first cylinder 14 can drive the first moving block 15 to move, thereby ensuring that the upper blocking arm 107 is directly above the extension arm 18 through the first moving block 15, completing the first guide. When the fourth cylinder 503 is started, the piston rod of the fourth cylinder 503 drives the fourth moving block 504 to move forward, thereby realizing the synchronous downward movement of the upper plate 507 and the lower plate 508. After the lower plate 508 moves forward for a certain distance, the lower plate 508 is just between the raised parts 314 on the left and right sides. At this time, the upper surface of the lower plate 508 is coplanar with the upper surface of the raised part 314, and the guide gap 509 between the lower surface of the upper plate 507 and the upper surface of the lower plate 508 and the guide channel formed by the lower surface of the cover plate 106 and the guide groove are in the same plane.

[0039] The paper tape 26 is then guided by the gap between the upper stop arm 107 and the extension arm 18, and the paper tape 26 is then guided by the gap between the upper stop arm 107 and the extension arm 18. At this time, the paper tape 26 is clamped between the lower end of the regulating wheel 20 and the upper end of the driving wheel 19.

[0040] When it is necessary to automatically convey the paper tape 26, the drive motor 201 can be started. At this time, the motor shaft of the drive motor 201 drives the first synchronous wheel to rotate, and the first synchronous wheel and the second synchronous wheel 211 are connected by a synchronous belt 212. When the first synchronous wheel rotates, the second synchronous wheel 211 rotates synchronously, and the second synchronous wheel 211 is connected to the driving wheel 19 through the driving shaft 210. Therefore, when the second synchronous wheel 211 rotates, the driving wheel 19 rotates accordingly, and the driving wheel 19 and the adjusting wheel 20 clamp the sticker. As the driving wheel 19 rotates, the driving wheel 19 can use friction to drive the adjusting wheel 20 to rotate synchronously, thereby realizing the conveyance of the paper tape 26, so that the paper tape 26 is continuously conveyed to the right, and the paper tape on the unwinding wheel 7 is continuously released.

[0041] With the continuous rightward conveying of the paper tape 26, the end of the paper tape 26 enters into the guiding channel formed by the lower surface of the cover plate 106 and the guiding groove 104 from the gap between the upper blocking arm 107 and the extension arm 18, and then enters into the guiding gap 509 between the upper plate 507 and the lower plate 508, and the double blades 5110 of the pneumatic scissors 511 are just between the guiding channel and the guiding gap 509. When the end of the paper tape 26 enters into the guiding gap 509 between the upper plate 507 and the lower plate 508, the paper tape 26 is between the double blades 5110 of the pneumatic scissors 511 at the same time. With the continuous rightward movement of the end of the paper tape 26, the end of the paper tape 26 is finally adsorbed by the air suction hole 315 on the right pad 314, and at the same time, the air suction hole 315 on the left pad 314 adsorbs the paper tape 26. After the paper tape 26 is adsorbed by the air suction holes 315 on the left and right sides, the stability of the paper tape 26 when being cut can be ensured, and the cutting quality can be effectively ensured. The air pipe 3150 penetrating through the air suction hole 315 is arranged on the clamping jaw 312, and the air pipe 3150 is directly connected with the existing negative pressure device, so that effective suction force can be generated, so that the upper end hole of the air suction hole 315 can generate corresponding suction force. When the right part of the paper tape 26 is adsorbed and fixed by the air suction holes 315 on the left and right sides, the pneumatic scissors 511 can be started. At this time, the double blades 5110 of the pneumatic scissors 511 are closed under the action of the cylinder of the pneumatic scissors 511, so that shearing force is generated, so that the part of the paper tape 26 between the double blades 5110 is cut off. At this time, the part of the paper tape 26 on the upper surface of the pad 314 is an independent individual.

[0042] When the cutting is completed, the pneumatic scissors 511 are reset, and the fourth cylinder 503 simultaneously drives the upper plate 507 and the lower plate 508 to move back and reset. At this time, the suction hole 315 still firmly absorbs the cut paper tape 26. At the same time, the clamping device on the disposable infusion set assembly equipment clamps the disposable infusion set that has been coiled into a ring structure to the top of the hinge head 311, and then the second cylinder 302 can be started. At this time, the piston rod of the second cylinder 302 will drive the second moving block 303 to move upward, thereby realizing the upward movement of the slide rail seat 304, and finally realizing the upward movement of the hinge head 311. When the hinge head 311 moves upward, the paper tape 26 above the clamping claws 312 on the left and right sides will move upward accordingly. When the paper tape 26 moves to the actual position, the paper tape 26 just touches the lower surface of the ring structure coiled by the disposable infusion set. When the hinged seat 308 moves up, the swing arm 313 moves up accordingly, and the upper end of the swing arm 313 is hinged to the clamping claw 312, and the clamping claw 312 is in an inverted L shape. When the hinged seat 308 moves up, the raised portions 314 on the left and right sides move up and approach each other, like the tips of two fingers pinched together, and the left and right ends of the independent paper tape 26 are just on the upper surfaces of the raised portions 314 on the left and right sides. When the raised portions 314 on the left and right sides are closed together, the left and right ends of the independent paper tape 26 are just stuck together, achieving the effect of tightening the ring structure formed by the disposable infusion set.

[0043] In summary, the present invention can not only automatically convey the paper tape 26, but also can automatically cut the paper tape 26 by using the pneumatic scissors 511 after the paper tape 26 is conveyed to the actually required position. The length of the cut paper tape 26 just meets the actual requirements. When the disposable infusion set is wound into a ring structure with the paper tape 26, the suction hole 315 can be used to firmly adsorb the paper tape 26 to ensure that the paper tape 26 can be folded in half and pasted stably through the clamping claw 312, thereby effectively ensuring the quality of the paper tape 26. When the paper tape 26 is pasted, the adsorption function of the suction hole 315 will be closed, and the other components will be reset at the same time. At the same time, the subsequent paper tape 26 is always in an automatic conveying state, thereby realizing uninterrupted paper tape 26 operation, always maintaining high work efficiency, and effectively avoiding the situation where the efficiency continues to decline in the later stage due to the manual pasting of the paper tape 26.
