One end of the carrying platform 204 is slidably assembled on the guide rod 202, and the other end of the carrying platform 204 is engaged with the screw rod 203. The first reversing wheel 205 is rotatably assembled on the carrying platform 204, and the conical cylinder 206 is fixedly arranged on one end of the carrying platform 204 and is arranged toward the side of the winding drum 105. The infusion tube to be wound is wound around the first reversing wheel 205, and the end of the infusion tube is passed through the conical cylinder 206. The end of the infusion tube is wound around the surface of the winding drum 105 and fixed in the elastic clip 103.

[0043] In actual application of this embodiment, a guide rod 202 is fixedly arranged on the sub-frame 201, and the carrying platform 204 is limitedly slidably assembled on the guide rod 202. The screw rod 203 is fixedly arranged on the sub-frame 201 and is driven by an independent external driving source, so that the screw rod 203 rotates in a clockwise and counterclockwise direction, thereby driving the carrying platform 204 to reciprocate in the first direction x. During the movement of the carrying platform 204, the infusion tube wound on the first reversing wheel 205 passes through the conical cylinder 206 and is continuously wound on the winding drum 105, so that the infusion tube is evenly wound on the outer surface of the winding drum 105, and the infusion tube is stacked on the winding drum 105, ensuring that the infusion tubes are closely connected, saving the space occupied by the infusion tubes.

[0044] See also Figure 2 and Figure 3In a preferred embodiment of the present embodiment, the tube winding assembly 2 further includes a fixed bracket 207, a movable bracket 208, a second reversing wheel 209, a pushing arm 210, a third reversing wheel 211 and a fourth reversing wheel 212, one end of the fixed bracket 207 is fixedly mounted on the sub-frame 201, and the other end of the fixed bracket 207 is slidably mounted with the movable bracket 208, the movable bracket 208 is rotatably mounted with the second reversing wheel 209, one end of the pushing arm 210 is rotatably connected to the carrying platform 204, and the other end of the pushing arm 210 is rotatably connected to the movable bracket 208, the third reversing wheel 211 and the fourth reversing wheel 212 are respectively arranged on the carrying platform 204 and the sub-frame 201, and the infusion tube to be wound is respectively wound around the second reversing wheel 209, the third reversing wheel 211 and the fourth reversing wheel 212.

The infusion tube wound on the second reversing wheel 209 and the third reversing wheel 211 is output to one end of the conical cylinder 206 via the first reversing wheel 205. When the carrying platform 204 moves toward one end close to the fixed bracket 207, the linear speed of the reel 105 on one side remains unchanged, so that the traction speed of the infusion tube remains unchanged. Since the carrying platform 204 continues to move relative to the fixed bracket 207, the infusion tube 206 is rotated in the first direction x. There is displacement, which causes the rolled-up infusion tube to become increasingly loose. Since a push arm 210 is rotatably mounted on one side of the carrying platform 204, and the end of the push arm 210 is rotatably mounted on the movable bracket 208, the movable bracket 208 is pushed to move in the positive direction of the third direction z, thereby causing the second reversing wheel 209 to tighten the loose infusion tube during the rising process to prevent the infusion tube from loosening and falling from the device. Similarly, when the carrying platform 204 moves toward the end away from the fixed bracket 207, the movable bracket 208 moves in the negative direction of the third direction z, thereby causing the continuously tightened infusion tube to gradually loosen, thereby preventing the infusion tube from being torn off due to excessive traction.

The infusion tube to be wound moves toward the side of the carrying platform 204 through the front pipe inlet groove 303. When a section of the infusion tube enters the rear pipe outlet groove 304, when the end of the infusion tube leaves the infrared sensor 307 at one end of the front pipe inlet groove 303, it is detected that the infusion tube is disconnected from here. At this time, the main driver 104 controls the winding drum 105 to stop rotating, and the screw rod 203 is simultaneously The first step stops rotating so that the end of the infusion tube stays at the infrared sensor 307 on the side of the rear tube outlet groove 304, and the infusion tube fed in subsequently is pushed to the infrared sensor 307 on the side of the front tube inlet groove 303 and then stops moving. At this time, the hot pressing head 306 is continuously pressed down by the cylinder 305, and the tube ends of the two infusion tubes are hot-pressed and bonded. After the bonding is formed, the main driver 104 continues to drive the winding drum 105 to rotate, and the screw rod 203 continues to move, so that the several disconnected sections of infusion tube are continuously formed after hot pressing, so that the whole is wound on the winding drum 105.

The fourth transmission shaft wheel 410 is transmission-connected to the third transmission shaft wheel 409.

[0050] In actual application of this embodiment, the curved baffle 404 is spirally arranged in the inner cavity of the material distribution shell 401 and is arranged around the outer cylinder 503. The sliders 505 on the several straight grooves 504 approach each other when approaching the top of the material distribution shell 401, and move away from each other when approaching the bottom of the material distribution shell 401, so that the infusion tube dropped into the feed port 403 is pulled by two sets of sleeves 509 to straighten the chaotically wound infusion tube. The main shaft 406 is independently driven by an external driving source, thereby driving the outer cylinder 503 to rotate around the inner cylinder 501, and at the same time engaging and driving the first transmission shaft wheel 407 to rotate, thereby driving the second transmission shaft wheel 408 and the third transmission shaft wheel 409 to rotate at the same time, so that the second transmission shaft wheel 408 drives the clamping assembly 6 to move, and the third transmission shaft wheel 409 drives the fourth transmission shaft wheel 410 to rotate.

[0051] Furthermore, the material distributing component 4 also includes a material blocking groove 411, a return gear 412 and a pressing belt 413. The two groups of the material blocking grooves 411 are fixedly arranged on both sides of the bottom notch 405. The return gear 412 is rotatably arranged in the groove of the material blocking groove 411 and is coaxially fixedly connected with the fourth transmission shaft wheel 410. A pressing belt 413 is also wound around the surface of the return gear 412. The fourth transmission shaft wheel 410 drives the return gear 412 to rotate during the rotation process. The pressing belt 413 wound around the return gear 412 can push the infusion tube that falls on one side of the bottom plate of the distributing shell 401 along the second The positive direction of direction y is pressed, and the infusion tube is moved to the side of the bottom groove 405, so that the tube clamping assembly 6 can clamp a single infusion tube from the bottom groove 405, and the infusion tube that is not clamped moves along the positive direction of the second direction y to the side of the return gear 412, and when it abuts against the side of the groove wall of the blocking groove 411, it is rotated and lifted to the top of the pressing belt 413 through the tooth plate on the return gear 412, so that the infusion tube that is not clamped moves along the negative direction of the second direction y to the initial position on the bottom plate side of the material distribution shell 401, so that the infusion tube that is not clamped is pressed to the bottom of the pressing belt 413 again, which is convenient for the tube clamping assembly 6 to clamp it.

[0052] See also Figure 9 In a preferred embodiment of the present invention, the pulling tube assembly 5 also includes a column rod 507 and a cutting edge 508. The column rod 507 is fixedly arranged on the slider 505, and a cutting edge 508 is fixedly provided on one side of the column rod 507. The sleeve 509 is elastically slidably sleeved on the column rod 507, and the cutting edge 508 is slidably inserted into the groove on the surface of the sleeve 509.

[0053] When this embodiment is actually used, the column rod 507 is fixedly set on the slider 505, and a cutting edge 508 is arranged at one end of the column rod 507. The cutting edge 508 is slidably inserted into the groove on the surface of the sleeve 509. When the two groups of sleeves 509 pull the infusion tube normally, since the two groups of sleeves 509 are subjected to limited force, the cutting edge 508 is still received inside the sleeve 509 under the action of elastic force. When the wound infusion tube is knotted, the two groups of sleeves 509 are continuously subjected to force when pulling the infusion tube, so that the sleeve 509 overcomes the elastic force and slides relative to the column rod 507, thereby making the cutting edge 508 pass through the groove on the surface of the sleeve 509 and abut against the infusion tube, thereby cutting off the knotted infusion tube, so that the long infusion tube that is randomly wound can be quickly broken into several short infusion tubes, which is convenient for clamping a single infusion tube.

[0054] See also Figure 10 、 Figure 11 and Figure 13In a preferred embodiment of the present invention, the clamping assembly 6 includes a driven disc 601, a pin hole 602, a bracket 603, a slide rod 604, a sleeve 605, a circular groove 606, a limiting hole 607, a built-in cavity 608, a curved slide 609 and a locking ring 610. The driven disc 601 is rotatably arranged at the bottom of the material distribution shell 401 and is coaxially fixedly connected to the second transmission shaft wheel 408. The outer diameter end of the driven disc 601 is circumferentially provided with a plurality of pin holes 602, and a plurality of the brackets 6 03 is fixedly assembled on the surface of the driven disk 601, and a slide rod 604 is assembled on the top of the bracket 603. The two groups of sleeve devices 605 are elastically slidably assembled on the slide rod 604. A circular groove 606 is also arranged in the middle of the sleeve device 605, and a limiting hole 607 is arranged on one side of the circular groove 606. A built-in cavity 608 is arranged inside the circular groove 606. The curved slide 609 is arranged in the built-in cavity 608 along the circular groove 606 in an annular direction, and the locking ring 610 is slidably assembled in the curved slide 609.

[0055] In actual application of this embodiment, the driven disc 601 is driven to rotate by the second transmission shaft wheel 408, and during the rotation of the driven disc 601, the multiple brackets 603 thereon rotate along with it. Since the two sets of sleeve devices 605 are elastically slidably assembled in the slide bar 604, when the bracket 603 rotates to one side of the bottom notch 405, the two sets of sleeve devices 605 are in a state of mutual contact, and in the process of passing through the bottom notch 405, the sleeve devices 605 are in a state of mutual contact. The V-shaped notch at the front end can clamp the infusion tube moving on the bottom notch 405 and slide the infusion tube into the circular groove 606. The diameter of the circular groove 606 is matched to the diameter of the infusion tube. After the single infusion tube is clamped in the circular groove 606, the locking ring 610 set in the built-in cavity 608 slides along the curved slide 609 after being triggered, and then moves around the infusion tube and is clamped into the limiting hole 607, so that the single infusion tube is clamped in the two sets of cannula devices 605.

[0056] Furthermore, since the front end of the sleeve device 605 is set as a V-shaped groove, after one infusion tube is stuck in the circular groove 606, the remaining infusion tubes are blocked outside the locking ring 610. As the driven disk 601 continues to rotate, the remaining infusion tubes slide along the groove wall of the V-shaped groove and detach from the group of sleeve devices 605, thereby preventing the sleeve device 605 from pulling multiple infusion tubes out of the bottom groove 405.

[0057] See also Figure 11 、 Figure 12 and Figure 13In a preferred embodiment of the present invention, the clamping assembly 6 further includes a strip groove 611, a connecting piece 612, an axial hole 613, a traction rod 614, a straight shaft hole 615, a trigger rod 616, a lifting frame 617, a lifting rod 618, a linkage arm 619, a reset rod 620, a U-shaped slot 621, a limit shaft rod 622 and a fixed slider 623. The back side of the sleeve 605 is provided with a strip groove 611, and the strip groove 611 and the built-in cavity 608 are connected. The connecting piece 612 is inserted into the strip groove 611, and the end of the connecting piece 612 is provided with an axial hole 613. The traction rod 614 is slidably inserted into the two sets of axial holes 613. The middle part of the sleeve 605 is also provided with a straight shaft hole 615. The trigger rod 616 is elastic Sliding into the straight shaft hole 615, the lifting frame 617 is slidably arranged on one side of the bracket 603, and the bottom of the lifting frame 617 is fixedly connected with a lifting rod 618, and the lifting rod 618 is slidably passed through the pin hole 602. The lifting frame 617 is also rotatably connected with two sets of linkage arms 619, and the ends of the two sets of linkage arms 619 are rotatably connected to the two sets of sleeves 605 respectively. One end of the reset rod 620 is rotatably connected to the lifting frame 617, and the end of the reset rod 620 is fixedly connected with a U-shaped groove 621, one end of the limiting shaft 622 is rotatably connected to the bracket 603, and the other end of the limiting shaft 622 is rotatably connected to the U-shaped groove 621, and the fixed sliding block 623 is arranged in the driven disk 601 and fixedly assembled at the bottom of the distributing shell 401.

[0058] In actual application of this embodiment, the strip groove 611 is arranged on the back side of the sleeve device 605, and the connecting piece 612 is provided with relative oblique grooves a1 and clamping grooves a2. In the default state, the connecting piece 612 is clamped on the strip groove 611 through the clamping groove a2, so that the connecting piece 612 overcomes the elastic force to pull the locking ring 610 into the curved slide 609. When the infusion tube enters the circular groove 606 along the V-shaped groove, the infusion tube will abut against the trigger rod 616, and the end of the trigger rod 616 is provided with a relative trigger surface a3. Therefore, when the trigger rod 616 slides along the straight axis hole 615, the trigger surface a3 contacts the oblique groove a1 and pushes the connecting piece 612 to move upward until the clamping groove a2 is disengaged from the strip groove 611. At this time, the connecting piece 612 slides toward the inside of the built-in cavity 608 under the action of elastic force, so that the locking ring 610 slides along the curved slide 609 and is stuck in the limit hole 607. At this time, the axial hole 613 at the end of the connecting piece 612 synchronously drives the traction rod 614 to move upward. When the infusion tube is clamped on the sleeve 605, the bracket 603 rotates out of the bottom notch 405. Since the bottom of the lifting rod 618 on one side of the bracket 603 slides against the fixed slider 623, and the fixed slider 623 has a first curved surface b1 and a second curved surface b2 relative to each other, when the bracket 603 rotates out of the bottom notch 405, the lifting rod 618 slides to the second curved surface b2, so that the lifting frame 617 moves toward the two sets of sleeves 605. The two sets of linkage arms 619 are brought closer together, so that the two sets of sleeve devices 605 are pushed on the sliding rod 604, and the two sets of sleeve devices 605 are moved away from each other, so that the infusion tubes clamped in the two sets of sleeve devices 605 are in a straight state, and at this time, the lifting frame 617 drives the reset rod 620 thereon to move synchronously as it continues to move upward. Since the end of the reset rod 620 is fixedly provided with a U-shaped groove 621, and the U-shaped groove 621 is rotatably connected to the limiting shaft 622, and the limiting shaft 622 is rotatably connected to the bracket 603, the U-shaped groove 621 can be rotated around the axis of the limiting shaft 622, and during the rotation process, the upper end of the U-shaped groove 621 slides into the bottom of the traction rod 614, thereby pushing the traction rod 614 to be stuck in the U-shaped groove. In the slot 621, when the lifting frame 617 moves downward in the opposite direction, the lifting frame 617 can pull the two groups of sleeve devices 605 closer to each other, and while the traction rod 614 is pulled by the U-shaped slot 621 and continues to move downward, the traction rod 614 is used to pull the connecting piece 612 toward the side away from the inner cavity 608, so that the slot a2 on one side of the connecting piece 612 is again stuck on the strip groove 611, so that the locking ring 610 slides and shrinks into the curved slide 609. At this time, the single infusion tube between the two groups of sleeve devices 605 can be released and transported to the side of the clamping conveyor 309 via the conveying structure, and transported along the clamping conveyor 309 and the fifth reversing wheel 308 to the front pipe inlet groove 303 for hot pressing with the remaining infusion tubes.

[0059] See also Figure 14 and Figure 15 In a preferred embodiment of the present invention, the rapid winding device for recovering the infusion tube further includes a tube feeding assembly 7, which includes a base plate 701, a guide rail 702, a motorized carrier 703, a main lever 704, a hook head 705, a clamp 706, a supporting cylinder 707, a side pressure plate 708, a tube pressing groove 709, a tube pressing wheel 710 and an end sensor 711. The base plate 701 is fixedly arranged on the bottom of the material distribution shell 401, and a guide rail 702 is provided on the base plate 701 along the second direction y. The motorized carrier 703 is slidably assembled on the guide rail 702, and the machine A main shift lever 704 is rotatably mounted on the movable platform 703, and a hook head 705 is rotatably mounted on the end of the main shift lever 704. A clip 706 is elastically mounted on one side of the hook head 705. One end of the supporting cylinder 707 is movably connected to the movable platform 703, and the movable axis of the supporting cylinder 707 is movably connected to the hook head 705. The side pressure plates 708 are fixedly mounted on both ends of the hook head 705. A pipe pressing groove 709 is also provided on the other side of the movable platform 703. Pipe pressing wheels 710 are rotatably mounted on both sides of the pipe pressing groove 709, and an end sensor 711 is also provided at one end of the pipe pressing groove 709.

[0060] In actual application of this embodiment, the motorized carrier 703 is driven by an external driving source and moves along the guide rail 702 in the second direction y. When the bracket 603 on the driven disk 601 rotates from the second curved surface b2 to the side close to the first curved surface b1, the motorized carrier 703 moves in the positive direction of the second direction y. The hook head 705 on it rotates counterclockwise in the yoz plane under the push of the supporting cylinder 707, thereby pulling the infusion tube between the two sets of cannula devices 605 toward the side of the pressure tube groove 709. The clamping piece 706 on one side of the hook head 705 can assist in clamping the infusion tube. When the hook head 705 rotates to the side of the tube pressing groove 709, the infusion tube can be pressed between the two sets of tube pressing wheels 710. The side pressure plates 708 set at both ends of the hook head 705 can pull the infusion tube in the negative direction of the third direction z from both sides, so that the infusion tube is stuck between the two sets of tube pressing wheels 710. At this time, the bracket 603 moves to the first curved surface b1. At this time, the two sets of sleeves 605 are close to each other. At this time, the locking rings 6 10 slides and retracts into the curved slide 609, thereby loosening the infusion tube from the two sets of sleeves 605, so that a single infusion tube is clamped between the two sets of tube pressing wheels 710. At this time, the motorized carrier 703 continues to move in the positive direction of the second direction y. Since an end sensor 711 is provided at one end of the tube pressing groove 709, the end sensor 711 can control the two sets of tube pressing wheels 710 to rotate and push the infusion tube in the negative direction of the first direction x when detecting the infusion tube on one side, until the tube head of the infusion tube moves to the end sensor. When the two sets of tube pressing wheels 710 are on one side of the end sensor 711, they stop moving, and the motorized carrier 703 moves to the extreme point position of the second direction y, and the tube head of the infusion tube is located on the side of the end sensor 711. When the extreme point position is reached, the two sets of tube pressing wheels 710 rotate in the opposite direction, thereby pushing the infusion tube out in the positive direction of the first direction x. The clamping conveyor belt 309 is set at the end position of the base plate 701, so that the pushed-out infusion tube enters the clamping conveyor belt 309, thereby realizing hot pressing bonding.

[0061] Furthermore, the motorized platform 703 reciprocates on the base plate 701 , and one complete movement cycle corresponds to the clamping and feeding process of a group of cannula devices 605 , thereby realizing the continuous feeding of multiple sections of infusion tubes.

[0062] The above embodiment of the present invention provides a rapid winding device for recycling infusion tubes. By arranging a reciprocating carrying platform 204 on one side of the winding drum 105 and a continuously rotating tube pulling assembly 5 inside the material distribution shell 401, the wound infusion tube can be pulled and straightened, and the straightened single infusion tube can be clamped by the tube clamping assembly 6 and transported to the hot pressing assembly 3 for hot pressing and bonding, so that the recovered multiple sections of infusion tubes can be evenly wound on the winding drum 105, avoiding the tedious steps of manually sorting the infusion tubes and effectively improving the recycling efficiency.

[0063] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
