Description

Technical Field

[0001] The present invention relates to an automatic packaging machine for infusion sets, belonging to the technical field of medical devices. Background Art

[0002] In the medical industry, disposable infusion tubes are often used. These tubular medical devices need to be wound and packaged with packaging bags when leaving the factory. When in use, they do not need to be disinfected again and only need to open the packaging bag to be used.

[0003] An infusion tube generally consists of a drip chamber assembly, a catheter, a puncture device, a liquid medicine filter, a flow regulator, a venous needle, etc. It has many components, a very long overall length, and a complex assembly process, such as the assembly of the needle and the tube body, the winding of the infusion tube, and the packaging of the wound infusion tube into a bag. Due to the particularity of the infusion tube, the winding and packaging of the infusion tube are mainly completed by manual operation at present. The biggest disadvantage of manual operation is low efficiency and it is easy to attach germs. Workers often need to be strictly disinfected, and at the same time, the operation needs to be carried out in a huge aseptic purification workshop, which consumes a large amount of energy and production space, has high costs, and it is difficult to guarantee the quality. Summary of the Invention

[0004] The purpose of the present invention is to overcome the shortcomings of the existing technology and provide an automatic packaging machine for infusion sets.

[0005] The technical solution adopted by the present invention to achieve the purpose is as follows:

[0006] The automatic packaging machine for infusion sets includes a feeding and loading mechanism, a picking and shifting mechanism, a tube winding mechanism, a packaging bag feeding mechanism, a bagging and transferring mechanism, and a packaging bag sealing mechanism. An operator places the infusion set on the feeding and loading mechanism, the picking and shifting mechanism moves the infusion set to the tube winding mechanism, the tube winding mechanism drives the infusion set to rotate and wind the tube, the picking and shifting mechanism moves the wound infusion set to the bagging and transferring mechanism, and at the same time, the packaging bag feeding mechanism places the packaging bag at the corresponding position of the bagging and transferring mechanism. After the bagging and transferring mechanism completes the bagging of the infusion set, it moves the infusion set to the packaging bag sealing mechanism for sealing.

[0007] As a further optimization of the above technical solution: the tube winding mechanism includes a rotation driving motor, a tube winding panel, a rotation fixture, a tube winding bottom plate, a limiting device, and a material trough device. When the rotation driving motor operates, it drives the rotation fixture to rotate. The tube winding panel is provided with a rotation hole, and the rotation fixture is located in the rotation hole. The limiting device is installed on the tube winding panel and is laid around the rotation hole. The tube winding panel is also provided with a right tube winding guide and a left tube winding guide.

[0008] As a further optimization of the above technical solution: The feeding and loading mechanism includes an infusion set fixture and a flat-laying mechanism. The infusion set fixture is installed on the flat-laying mechanism. The flat-laying mechanism includes a limiting device, a dislocation device, a swing rod cylinder, and a rotating fixing plate. When the infusion set fixture is feeding, it is vertically placed, and when loading, it is driven by the swing rod cylinder to flip 90° to a horizontal placement.

[0009] As a further optimization of the above technical solution: The dislocation device includes a flat-laying bottom plate. A rotating cylinder joint is installed at the bottom of the flat-laying bottom plate. The swing rod cylinder is installed on the rotating cylinder joint. A dislocation fixing plate is installed on the flat-laying bottom plate. Dislocation guide rods are provided at both ends of the dislocation fixing plate. One end of the dislocation guide rod is fixed on a dislocation retaining frame, and the other end is installed on a dislocation side plate. The infusion set fixture is installed on the dislocation side plate. A dislocation cylinder bracket is also installed on the dislocation fixing plate. A dislocation cylinder is fixed on the dislocation cylinder bracket. The piston rod of the dislocation cylinder passes through the dislocation fixing plate and is installed with a dislocation joint. A dislocation joint seat is installed on the dislocation side plate. The dislocation joint is connected in cooperation with the dislocation joint seat.

[0010] As a further optimization of the above technical solution: The feeding and loading mechanism is installed on a feeding bottom plate. The picking and shifting mechanism is slidably installed on a bracket. The bagging and transferring mechanism and the packaging bag sealing mechanism are both installed on a bracket bottom plate. Several groups of the feeding and loading mechanism, the picking and shifting mechanism, the tube winding mechanism, the bagging and transferring mechanism, and the packaging bag sealing mechanism are arranged side by side. There are two groups of the packaging bag feeding mechanism. The packaging bag feeding mechanism includes a feeding trough bottom plate, and the feeding trough bottom plate is fixed on both sides of the bracket bottom plate.

[0046] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Figures 1 - 34As shown in the figure, the automatic packaging machine for infusion sets includes a feeding and loading mechanism 1, a picking and shifting mechanism 2, a tube winding mechanism 3, a packaging bag feeding mechanism 4, a bagging and transferring mechanism 5, and a packaging bag sealing mechanism 6. An operator places the infusion set on the feeding and loading mechanism 1, and the picking and shifting mechanism 2 moves it to the tube winding mechanism 3. The tube winding mechanism 3 drives the infusion set to rotate and wind the tube. The picking and shifting mechanism 2 moves the tube-wound infusion set to the bagging and transferring mechanism 5. At the same time, the packaging bag feeding mechanism 4 places the packaging bag at the corresponding position of the bagging and transferring mechanism 5. The bagging and transferring mechanism 5 completes the bagging of the infusion set and moves the packaging bag to the packaging bag sealing mechanism 6 for sealing.

[0047] In the above technical solution: as Figure 33 , 34 shown, the feeding and loading mechanism 1 is installed on the feeding bottom plate 7, the picking and shifting mechanism 2 is slidably installed on the upper part of the bracket 9. The tube winding mechanism 3 includes a tube winding bottom plate 36. The bagging and transferring mechanism 5 and the packaging bag sealing mechanism 6 are both installed on the bracket bottom plate 8. The feeding and loading mechanism 1, the picking and shifting mechanism 2, the tube winding mechanism 3, the bagging and transferring mechanism 5, and the packaging bag sealing mechanism 6 are all provided with several groups arranged in parallel. In this embodiment, there are four groups arranged in parallel. The packaging bag feeding mechanism 4 is provided with two groups. The packaging bag feeding mechanism 4 includes a feeding trough bottom plate 42, and the feeding trough bottom plate 42 is fixed on both sides of the bracket bottom plate 8.

[0048] In the above technical solution: as Figures 1 - 4 shown, the feeding and loading mechanism 1 includes an infusion set fixture and a horizontal placement mechanism. The infusion set fixture is installed on the horizontal placement mechanism. The horizontal placement mechanism includes a limiting device, a dislocation device, a swing rod cylinder 11, and a rotating fixing plate 17. When the infusion set fixture feeds the material, it is placed vertically, and when loading the material, it is driven by the swing rod cylinder 11 to flip 90° to a horizontal placement.

[0049] In the above technical solution: the infusion set jig includes a fixed bottom plate 12, and a plurality of mounting grooves 127 are formed on the fixed bottom plate 12. A top stop block 13, an infusion set positioning stop block 14, a drip chamber stop block 15 and a catheter stop block 16 are sequentially fixed on the mounting groove 127. Each stop block is composed of a fixing plate 145 and a support plate perpendicular to the fixing plate 145. A fixing hole 144 is formed on the fixing plate 145, and an insertion block 146 matching with the mounting groove 127 is formed at the bottom of the fixing plate 145. The length of the mounting groove 127 enables each stop block to translate on the fixed bottom plate 12 to adjust the position. A puncture device sliding slope 131 is further formed on the support plate of the top stop block 13. U-shaped grooves 142 are formed on the upper parts of the support plates of the infusion set positioning stop block 14 and the drip chamber stop block 15. Sliding slopes 141 are formed at the upper ends of the two inner walls of the U-shaped groove 142. A catheter groove is formed on the support plate of the catheter stop block 16, and the two side surfaces of the catheter groove are formed into catheter sliding slopes.

[0050] In the above technical solution: the fixing hole 144 is in the shape of an oblong ellipse with semicircles at both ends and a rectangle in the middle. A screw passes through the fixing hole 144 to mount each stop block on the fixed bottom plate 12. This shape provides a certain moving space for the screw in the fixing hole 144, enabling each stop block to move relative to the fixed bottom plate 12. That is, when the sizes of the infusion sets are inconsistent, each stop block can slightly move its position on the fixed bottom plate 12 to make it suitable for infusion sets of different sizes.

[0051] In the above technical solution: such as Figure 4As shown, plunger screw holes are formed on both sides of the U-shaped groove 142, and plunger screws 143 are installed in the plunger screw holes. The plunger screw 143 includes a spring 1433 and a ball 1431 and a positioning plug 1432 respectively located at both ends of the spring 1433. The positioning plug 1432 installs the plunger screw 143 in the plunger screw hole, and a part of the spherical surface of the ball 1431 protrudes from the inner surface of the U-shaped groove 142. When discharging, the infusion pump is inserted into the U-shaped groove 142 and squeezes the ball 1431 protruding from the inner surface of the U-shaped groove 142. The spring 1433 is compressed and the ball 1431 retracts into the plunger screw hole. When the infusion pump enters the U-shaped groove 142, the ball 1431 is no longer squeezed, the spring 1433 is elastically released, and the ball 1431 returns to the state of protruding from the inner surface of the U-shaped groove 142, and plays a positioning role for the infusion pump in the U-shaped groove 142 to prevent it from falling off during the loading process. When taking materials, the material taking assembly clamps the infusion pump and moves upward. During the upward movement, the infusion pump squeezes the ball 1431 protruding from the inner surface of the U-shaped groove 142, the spring 1433 is compressed, and the ball 1431 retracts into the plunger screw hole until the infusion pump is completely out of the U-shaped groove 142. At this time, the ball 1431 is no longer squeezed, the spring 1433 is elastically released, and the ball 1431 returns to the state of protruding from the inner surface of the U-shaped groove 142.

[0052] In the above technical solution: the dislocation device includes a flat bottom plate 18, a rotary cylinder joint 19 is installed at the bottom of the flat bottom plate 18, the rocker cylinder 11 is installed on the rotary cylinder joint 19, and a dislocation fixing plate 110 is installed on the flat bottom plate 18. Both ends of the dislocation fixing plate 110 are provided with a dislocation guide rod 111, one end of the dislocation guide rod 111 is fixed to the dislocation retaining frame 112, and the other end is installed on the dislocation side plate 113. The infusion jig is mounted on the offset side plate 113. The offset fixed plate 110 is also mounted with an offset cylinder bracket 117. The offset cylinder bracket 117 is fixed with an offset cylinder 114. The piston rod of the offset cylinder 114 passes through the offset fixed plate 110 and is mounted with an offset joint 115. The offset side plate 113 is mounted with an offset joint seat 116. The offset joint 115 is mated with the offset joint seat 116. The offset device offsets the infusion jig from the rocker cylinder 11, so that the infusion jig does not interfere with the material removal mechanism during the 90° flipping process. After the flip is completed, the infusion jig is in a flat position and can be located just below the material removal mechanism, making it convenient for material removal. When the infusion jig deviates from the material removal mechanism, the piston rod of the offset cylinder 114 drives the infusion jig and the infusion jig to move horizontally below the material removal mechanism, making it convenient for material removal.

[0053] In the above technical solution: The limiting mechanism includes a first positioning stop nut 118, a second positioning stop nut 120, a vertical limiting block 121 and a horizontal rotation shaft 122. A horizontal buffer seat 119 is installed on the rotation fixing plate 17. The first positioning stop nut 118 is installed on the horizontal buffer seat 119. A bearing seat bottom plate 126 is also installed on the rotation fixing plate 17. A first bearing side plate 123 and a second bearing side plate 125 are respectively installed at both ends of the bearing seat bottom plate 126. One end of the horizontal rotation shaft 122 passes through the first bearing side plate 123 and is fixed to the vertical limiting block 121. The other end of the horizontal rotation shaft 122 passes through the second bearing side plate 125 and is fixed to the horizontal bottom plate 18. A vertical buffer seat 124 is installed at the top of the first bearing side plate 123. The second positioning stop nut 120 is fixed on the vertical buffer seat 124. The first positioning stop nut 118 and the second positioning stop nut 120 play a role of limiting and buffering during the flipping process.

[0054] In the above technical solution: As Figures 5 - 10As shown, the material taking and shifting mechanism 2 includes a material taking component, a shifting component, and a translation cylinder 21. The material taking component includes a material taking plate 23. A material taking cylinder 22 is installed on the bottom surface of the material taking plate 23. The piston rod of the material taking cylinder 22 is connected to a first clamping device. The shifting component includes a material shifting plate 24. A material pulling cylinder 25 is installed on the bottom surface of the material shifting plate 24. The piston rod of the material pulling cylinder 25 is connected to a second clamping device. The fixing method of the material taking cylinder 22 and the material taking plate 23 is as follows: The material taking cylinder 22 is fixed on the cylinder side plate. The top of the cylinder side plate is fixed to the cylinder seat at the bottom of the material taking plate 23. A reinforcing rib is also installed between the cylinder side plate and the cylinder seat. The fixing method of the material pulling cylinder 25 and the material shifting plate 24 is the same as the fixing method of the above-mentioned material taking cylinder 22 and the material taking plate 23. Sliders 27 are installed on both the material taking plate 23 and the material shifting plate 24. Slide rails 26 are provided on the sliders 27. The sliders 27 can slide within the slide rails 26. The slide rails 26 are fixed on the bracket 9. A material pulling front buffer seat 261 and a material pulling rear buffer seat 262 are respectively installed at both ends of the slide rails 26. The cooperation between the sliders 27 and the slide rails 26 enables the material taking plate 23 and the material shifting plate 24 to slide. The material pulling front buffer seat and the material pulling rear buffer seat prevent the material taking plate 23 and the material shifting plate 24 from sliding out of the slide rails 26. A translation cylinder 21 and a material pulling drag chain box 223 are also installed on the material shifting plate 24. A manipulator connecting plate 222 is fixedly connected between the material taking plate 23 and the material shifting plate 24. The translation cylinder 21 can drive the material taking component and the shifting component to translate synchronously. The material taking cylinder 22 drives the first clamping device to descend to take materials. The material pulling cylinder 25 drives the second clamping device to descend to pull materials. After the feeding and loading are completed, the translation cylinder 21 drives the material taking component to move directly above the loading mechanism. Then, the material taking cylinder 22 drives the first clamping device to descend, clamp the infusion set, and then rise and reset. The translation cylinder 21 drives the material taking component to move directly above the tube winding mechanism. The material taking cylinder 22 drives the first clamping device to descend and place the infusion set on the tube winding mechanism and then rise and reset. After the tube winding mechanism finishes winding the tube, the translation cylinder 21 drives the shifting component to move directly above the tube winding mechanism. The material pulling cylinder 25 drives the second clamping device to descend and enter the infusion set that has been wound into a loop. Then, through the action of the translation cylinder 21, the infusion set that has been wound into a loop is shifted to the corresponding position of the bag loading and moving mechanism 5. During the entire movement process of the translation cylinder 21, the material taking component and the shifting component are driven to translate synchronously.

[0055] In the above technical solution: As Figure 6As shown, the first gripping device includes a gripper mounting plate 28, which is mounted on the piston rod of the material-retrieving cylinder 22. Gripper adjustment blocks 29 are mounted on both ends of the gripper mounting plate 28. A front gripper cylinder 210 and a rear gripper cylinder 211 are mounted on the two gripper adjustment blocks 29, respectively. The front gripper cylinder 210 is connected to a front gripper bracket 212. Two front grippers 213 are mounted on the front end of the front gripper bracket 212. A right rear gripper 214 and a left rear gripper 215 are mounted on the rear end of the front gripper bracket 212. Two tracheal grippers 216 are mounted on the piston rods on both sides of the rear gripper cylinder 211. After loading and unloading, the first gripping device descends to the infusion jig to retrieve the material. The position where the first gripping device grips the infusion jig is offset from the position where the infusion jig secures the infusion jig.

[0056] In the above technical solution: Figure 7 As shown, the head of the front air gripper 213 is formed with a semicircular puncture device fixing block 2131, one side of the upper end of the puncture device fixing block 2131 is formed with a front air gripper protrusion 2132, and the other side is formed with a front air gripper groove 2133 that cooperates with the front air gripper protrusion 2132. The two front air grippers 213 cooperate with each other to clamp the puncture needle part of the infusion set. Figure 8 As shown, the right rear clamping jaw 214 includes a first conduit fixing block 2141 with a semicircular head and a clamping jaw protrusion 2142. Figure 9 As shown, the left rear clamping jaw 215 includes a second catheter fixing block 2151 with a semicircular head and a clamping jaw groove 2152. The right rear clamping jaw 214 and the left rear clamping jaw 215 cooperate with each other to clamp the end of the infusion tube. The middle part of the tracheal clamping jaw 216 is provided with a clamping step. The upper end of the clamping step is fixed to the piston rod on both sides of the rear clamping jaw cylinder 211, and the lower end of the clamping step cooperates with each other to clamp the catheter part of the infusion set.

[0057] In the above technical solution: Figure 10As shown in the figure, the second clamping device includes a blanking adjustment plate 217, which is installed on the blanking cylinder 25. At both ends of the bottom of the blanking adjustment plate 217, blanking stoppers 218 are installed. When the blanking stoppers 218 move the material, they extend into the coiled infusion set and just clamp both ends of the coiled infusion set. A blanking pressure column 219 is installed on the blanking stopper 218, and the blanking pressure column 219 presses the catheter part of the coiled infusion set. A blanking middle stopper 220 is also installed at the bottom of the blanking adjustment plate 217. A semi-circular groove is made at the lower end of the blanking middle stopper 220, and the semi-circular groove of the blanking middle stopper 220 clamps the drip chamber part of the infusion set. A blanking inductor 221 is installed on the blanking middle stopper 220, and the blanking inductor 221 is used to sense whether there is a product below the second clamping device to prevent empty grasping.

[0058] In the above technical solution: As Figures 11 - 14 shown in the figure, the tube winding mechanism 3 includes a rotary drive motor 31, a tube winding panel 310, a rotary jig, a limiting device and a material tank device. A rotary shaft 32 is connected to the rotary drive motor 31. The rotary shaft 32 sequentially passes through a motor fixing plate 33, a detection disc 34, a rotary sleeve 35, a tube winding bottom plate 36 and is connected to a rotary bottom plate 37. A photoelectric adjustment plate is also provided on the side of the detection disc 34. The detection disc 34 and the photoelectric adjustment plate cooperate to detect the origin of the rotary drive motor 31. A lifting guide rod 38 is fixed on the rotary bottom plate 37. The lifting guide rod 38 passes through a lifting bottom plate 39 and is connected to the rotary jig. A telescopic cylinder 323 is also fixed on the rotary bottom plate 37. A cylinder fixing block 324 is fixed at the bottom of the lifting bottom plate 39. The piston rod of the telescopic cylinder 323 is installed on the cylinder fixing block 324. When the piston rod of the telescopic cylinder 323 moves, it drives the lifting bottom plate 39 to lift and lower along the lifting guide rod 38. When the rotary drive motor 31 operates, it drives the rotary jig to rotate. A rotary hole is made on the tube winding panel 310, and the rotary jig is located in the rotary hole. The limiting device is installed on the tube winding panel 310 and is laid around the rotary hole. A tube winding right guide 312 and a tube winding left guide 313 are also installed on the tube winding panel 310. The tube winding right guide 312 and the tube winding left guide 313 play a role in limiting the catheter during tube winding to prevent the catheter from flinging around randomly. The tube winding panel 310 is connected to the tube winding bottom plate 36 through a tube winding side plate 331. The material tank device is located at the feeding place of the tube winding mechanism 3.

[0059] In the above technical solution: the rotary fixture includes a rotary disk 311 and a fixing device. The bottom of the rotary disk 311 is connected to the lifting guide rod 38. The rotary disk 311 and the tubing panel 310 are in the same plane. The bottom of the fixing device passes through the rotary disk 311 and is fixed on the lifting bottom plate 39. The fixing device rises and falls with the lifting bottom plate 39. As Figure 11 , 12 shown, the fixing device includes a catheter stopper group 315 at both ends of the rotary disk 311 and a drip chamber stopper group 314 between the catheter stopper group 315. The drip chamber stopper group 314 is composed of two relatively arranged first stoppers 3141. One opposite corner at the upper end of the first stopper 3141 is made into an inclined surface. The catheter stopper group 315 is composed of two middle second stoppers 3151 and third stoppers 3152 on both sides. The second stoppers 3151 and the third stoppers 3152 are arranged in an arc shape. Both corners at the upper end of the second stopper 3151 are made into inclined surfaces. One corner of the upper end of the third stopper 3152 opposite to the second stopper 3151 is made into an inclined surface. The setting of the inclined surfaces facilitates the fitting and installation between the infusion set and the fixing device. The tail of the drip chamber of the infusion set is clamped between the drip chamber stopper group 314. The catheter of the infusion set extends out between the two second stoppers 3151 and hangs on the trough device.

[0060] In the above technical solution: the limiting device includes an elastic stopper 317, a needle-shaped cylinder 325 and a tension spring 326. The limiting device is installed on the tubing panel 310 by an elastic pad seat 316. The cylinder body of the needle-shaped cylinder 325 is fixed on the elastic pad seat 316. The piston rod is connected to the tail of the elastic stopper 317. The head of the elastic stopper 317 is located on the rotary disk 311. When winding the tubing, the needle-shaped cylinder 325 drives the elastic stopper 317 to swing closely against the infusion set on the rotary fixture. The tension spring 326 is installed on the elastic pad seat 316 and cooperates with the elastic stopper 317. The pulling force of the tension spring 326 enables the elastic stopper 317 to quickly reset after the swing stops. When the rotary fixture is driven by the rotary drive motor 31 to rotate, the catheter of the infusion set is wound around the periphery of the catheter stopper group 315 into an approximate ellipse under the action of the limiting device.

[0061] In the above technical solution: the trough device includes a front guide plate 318, the front guide plate 318 includes a feeding port with an arc-shaped head, a trough left baffle 320 and a trough right baffle 321 are installed on the feeding port, one end of the trough right baffle 321 is provided with a baffle notch, a trough movable baffle 319 is arranged inside the trough right baffle 321, the head of the trough movable baffle 319 extends out of the baffle notch, a trough rotating shaft 327 is connected below the trough movable baffle 319, the trough rotating shaft 327 passes through the front guide plate 318 and is fixed to a stop swinging block 322, an end of the stop swinging block 322 is connected with a swinging air cylinder 330, a rotating shaft bearing seat 328 and a swinging air cylinder seat 329 are installed at the bottom of the feeding port, the trough rotating shaft 327 is installed on the rotating shaft bearing seat 328, and the swinging air cylinder 330 is fixed to the swinging air cylinder seat 329. During feeding, the infusion set is fixed on the rotary fixture, the catheter part of the infusion set hangs on the front guide plate 318, the swinging air cylinder 330 drives the trough movable baffle 319 to rotate a certain angle through the stop swinging block 322 and the trough rotating shaft 327, so that the trough movable baffle 319 and the trough left baffle 320 cooperate to press the catheter of the infusion set, prevent the catheter from randomly swinging due to the rotational force generated during tube winding, and keep it in a tensioned state for convenient winding.

[0062] In the above technical solution: as Figure 14 shown, a plurality of winding mechanisms 3 are arranged in parallel and are controlled by the same rotary drive motor 31. A turntable 332 is also fixed on the rotating shaft 32. A synchronous belt 333 is sleeved between adjacent turntables 332, and a tensioning device is arranged on the synchronous belt 333.

[0063] In the above technical solution: The tensioning device includes a tensioning wheel 334, the tensioning wheel 334 is in close contact with the surface of the synchronous belt 333, a tensioning fixing column 335 is fixed to the bottom of the pipe winding bottom plate 36, a tensioning positioning block 336 is fixed to the lower end of the tensioning fixing column 335, two tensioning guide rods 337 are horizontally arranged on the tensioning positioning block 336, one end of the tensioning guide rod 337 is fixed with a tensioning bottom plate 339, the other end is fixed with a tensioning block 338, a tensioning wheel shaft 340 is connected below the tensioning block 338, a nut is fixed to the bottom of the tensioning wheel shaft 340, and the tensioning wheel 334 is sleeved outside the tensioning wheel shaft 340 and positioned by the nut. When the synchronous belt 333 is slack, manually push the tensioning guide rod 337 towards the tensioning positioning block 336, so that the tensioning block 338 drives the tensioning wheel 334 to press the synchronous belt 333 inward, thereby adjusting the tightness of the synchronous belt 333. When the rotary drive motor 31 rotates, the first pipe winding mechanism 3 driven to rotate transmits the rotation action to the adjacent next pipe winding mechanism 3 through the synchronous belt 333, and so on. All the pipe winding mechanisms 3 will be driven to rotate synchronously by relying on a rotary drive motor 31 through the cooperation of the synchronous belt 333, which is energy-saving and environment-friendly.

[0064] In the above technical solution: As Figures 15 - 17 shown, the packaging bag feeding mechanism 4 includes a packaging bag feeding groove 41, a bag taking suction cup assembly and a bag taking up and down mechanism. A number of required packaging bags are placed in the packaging bag feeding groove 41. The bag taking up and down mechanism drives the bag taking suction cup assembly to suck the packaging bag and place it on the bag entering and moving mechanism 5. A feeding groove bottom plate 42 is fixed below the packaging bag feeding groove 41, and the feeding groove bottom plate 42 is connected with a lifting mechanism, and the lifting mechanism controls the height of the packaging bags in the packaging bag feeding groove 41.

[0065] In the above technical solution: The bag taking up and down mechanism includes a bag sucking moving plate 43 and a bag taking cylinder 44. Moving bag sliders 45 are arranged at both ends of the bottom of the bag sucking moving plate 43, and the moving bag sliders 45 cooperate with moving bag slide rails 427, and the moving bag slide rails 427 are fixed on the bracket 9. Two bag sucking guide rods 46 are longitudinally arranged on the bag sucking moving plate 43. The upper ends of the bag sucking guide rods 46 are fixed to a guide rod connecting block 47, and the lower ends are connected to a bag sucking lower pressing plate 48. A bag taking suction cup assembly is connected below the bag sucking lower pressing plate 48. A wire passing pipe 49 is also connected between the guide rod connecting block 47 and the bag sucking lower pressing plate 48. The wire passing pipe 49 makes the connection between the guide rod connecting block 47 and the bag sucking lower pressing plate 48 more firm. The cylinder body of the bag taking cylinder 44 is fixed on the bag sucking moving plate 43, and the piston rod of the bag taking cylinder 44 passes through the bag sucking moving plate 43 and is connected to the bag sucking lower pressing plate 48. The bag taking cylinder 44 drives the bag taking suction cup assembly to pick up and place materials.

[0066] In the above technical solution: the bag-taking suction cup assembly includes a suction cup fixing plate 410 and four suction cup buffer rods 411. The suction cup fixing plate 410 is fixed below the bag-sucking lower pressing plate 48. A material pressing support column 414 is fixed below the suction cup fixing plate 410. The material pressing support column 414 is connected to a suction cup material pressing plate 415. Suction cup holes are made at the four corners of the suction cup material pressing plate 415. The upper ends of the four suction cup buffer rods 411 are respectively fixed at the four corners of the bottom surface of the suction cup fixing plate 410, and a bag-taking suction cup 412 is installed at the lower end. The suction head part of the bag-taking suction cup 412 passes through the suction cup holes of the suction cup material pressing plate 415 and is driven by the bag-taking up-and-down mechanism to extend into the packaging bag feeding slot 41 to take the bag by suction. A spring 413 is also sleeved outside the suction cup buffer rod 411. The two ends of the spring 413 are respectively in contact with the protrusion at the upper end of the suction cup buffer rod 411 and the bag-taking suction cup 412. The height of each bag-taking suction cup 412 is adjusted through its restoring force to prevent the situation that the bag-taking suction cup 412 cannot suck the bag due to the different heights of the four corners of the bag.

[0067] In the above technical solution: The lifting mechanism includes a feeding chute support rod 416. The upper end of the feeding chute support rod 416 is located inside the packaging bag feeding chute 41 and supports the packaging bag, while the lower end extends out of the feeding chute bottom plate 42 and is fixed on the support rod bottom plate 417. A transfer guide rod 418 is fixed to the bottom of the feeding chute bottom plate 42. A feeding chute position sensor 419 is fixed on the transfer guide rod 418. There are two groups of the feeding chute position sensors 419, which are respectively located at the upper and lower ends of the transfer guide rod 418. A position detection block is provided on the side of the support rod bottom plate 417 opposite to the feeding chute position sensor 419. The lower end of the transfer guide rod 418 is connected to a transfer bottom plate 420. A motor support rod 421 is fixed to the bottom of the transfer bottom plate 420. The lower end of the motor support rod 421 is connected to a motor bottom plate 422. A micro AC reduction motor 425 is fixed to the bottom surface of the motor bottom plate 422. A screw rod 424 is also fixed to the bottom of the feeding chute bottom plate 42. A nut 426 is installed on the support rod bottom plate 417. The screw rod 424 cooperates with the nut 426. The lower end of the screw rod 424 passes through the transfer bottom plate 420 and is connected to a coupling 423. The lower end of the coupling 423 passes through the motor bottom plate 422 and is connected to the micro AC reduction motor 425. Sensors are provided on both sides of the packaging bag feeding chute 41. The height where the sensors are located is the lowest height at which the bag-taking suction cup 412 can suck the packaging bag. When the height of the packaging bag in the packaging bag feeding chute 41 decreases below the height where the sensors are located as the number of used packaging bags decreases, the sensors receive the signal and start the micro AC reduction motor 425. The micro AC reduction motor 425 drives the screw rod 424 to rotate through the coupling 423, so that the support rod bottom plate 417 rises along the screw rod 424 in cooperation with the nut 426, and thus the feeding chute support rod 416 drives the packaging bag in the packaging bag feeding chute 41 to move upward until the sensors sense the packaging bag, preventing the situation that the bag-taking suction cup assembly grabs nothing. When the packaging bags in the packaging bag feeding chute 41 are used up, the position detection block on the support rod bottom plate 417 contacts the feeding chute position sensor 419 at the upper end of the transfer guide rod 418 and then provides a stop signal to the micro AC reduction motor 425. The cooperation between the position detection block and the feeding chute position sensor 419 limits the moving distance of the support rod bottom plate 417 on the screw rod 424, preventing the situation that the support rod bottom plate 417 rises and falls excessively, resulting in the feeding chute support rod 416 moving upward excessively and touching and damaging the upper components.

[0068] In the above technical solution: Two packaging bag feeding troughs 41 are arranged side by side on the bottom plate 42 of the feeding trough. The lifting mechanism simultaneously controls the height of the packaging bags in the two packaging bag feeding troughs 41. There are two bag-taking up-and-down mechanisms and two bag-taking suction cup assemblies respectively. Each bag-taking up-and-down mechanism and the bag-taking suction cup assembly cooperate with each other to form a group, and the two groups are arranged side by side on the bag-transferring slide rail 427. A middle push cylinder 428 is arranged between the two bag-taking up-and-down mechanisms, and the middle push cylinder 428 adjusts the distance between the two bag-taking up-and-down mechanisms. One side of the bag-sucking moving plate 43 is installed with the piston rod of the outer push cylinder 429 through an outer push connecting block 430, and the other side of the bag-sucking moving plate 43 is installed with a bag-sucking drag chain box 431. The bag-transferring slider 45 cooperates with the bag-transferring slide rail 427 to drive the two groups of bag-taking up-and-down mechanisms to move together between the packaging bag feeding trough 41 and the bag-inserting and transferring mechanism 5 by the outer push cylinder 429. A positioning stop nut 432 is also installed on one side surface of the bag-transferring slide rail 427, and the cooperation between the outer push connecting block 430 and the positioning stop nut 432 plays a role of buffering and limiting.

[0069] In the above technical solution: As Figures 18 - 26 shown, the bag-inserting and transferring mechanism 5 includes a shifting bin 52, a shifting mechanism, a bag-opening mechanism, and a bag-inserting mechanism. The shifting bin 52 receives the wound infusion sets. The bag-opening mechanism receives and opens the packaging bag. The shifting mechanism drives the shifting bin 52 to move the wound infusion sets into the packaging bag, and continues to drive the packaging bag to move into the bag-inserting mechanism together. After the bag-inserting mechanism positions the packaging bag and the infusion set, the shifting mechanism drives the shifting bin 52 to withdraw from the packaging bag and reset. Subsequently, the bag-inserting mechanism drives the packaging bag containing the infusion set to rotate 90° to cooperate with the next mechanism.

[0070] In the above technical solution: As Figure 19 shown, the shifting bin 52 is a cuboid structure with a hollow interior. A rectangular observation port is made on the upper surface of the shifting bin 52. After the shifting component of the material-taking and shifting mechanism 3 translates the wound infusion sets into the shifting bin 52, it can directly exit vertically from the observation port and reset, while the infusion sets are stuck by the observation port and remain in the shifting bin 52. A U-shaped notch is made at one end of the bottom of the shifting bin 52 close to the bag-opening mechanism. A shifting plate 548 is fixed on one side of the shifting bin 52, and the shifting plate 548 installs the shifting bin 52 on the shifting mechanism, so that the shifting bin 52 can move synchronously with the shifting mechanism.

[0071] In the above technical solution: The bag-opening mechanism includes an opening device and a bag-receiving device. As Figure 20As shown, the opening device includes an upper support plate 53, a lower support plate 56, an opening bottom plate 513, an opening cylinder 57 and a bag receiving cylinder 517. An upper support fixing plate 54 is fixed above the upper support plate 53. An upper support side plate 55 is installed on the side of the upper support fixing plate 54. The lower end of the upper support side plate 55 is fixed on a side cylinder plate 511. The lower support plate 56 is installed on the piston rod of the opening cylinder 57. A cylinder limit block 510 is installed between the piston rod and the cylinder block of the opening cylinder 57. An opening back plate is fixed on the opening cylinder 57. An opening limit block 59 is provided on the opening back plate. The side of the opening cylinder 57 is fixed on the side cylinder plate 511. The lower ends of the opening back plate and the side cylinder plate 511 are both fixed on an opening moving plate 515. An opening slider 514 is provided below the opening moving plate 515. An opening slide rail 512 is installed on the opening bottom plate 513. The opening slider 514 and the opening slide rail 512 cooperate with each other. An opening fixing plate 516 is fixed on the opening bottom plate 513. The cylinder block of the bag receiving cylinder 517 is fixed on the opening fixing plate 516. The piston rod of the bag receiving cylinder 517 is connected to the side cylinder plate 511. When the bag receiving device receives a packaging bag, the opening cylinder 57 drives the lower support plate 56 to move upward. The bag receiving cylinder 517 drives the opening moving plate 515 to move backward to the front of the bag receiving device in cooperation with the opening slider 514 and the opening slide rail 512. The upper and lower support plates 53 and 56 enter the packaging bag. Then the opening cylinder 57 drives the lower support plate 56 to move downward to open the packaging bag. The bag receiving cylinder 517 drives the opening moving plate 515 to reset to receive the infusion set into the bag. Above the opening fixing plate 516, a connection adjustment plate 518 is fixed. Above the connection adjustment plate 518, a connection side plate 519 is fixed. Above the connection side plate 519, a connection baffle 58 is fixed. The connection baffle 58 just blocks the U-shaped notch on the lower surface of the displacement bin 52 to prevent the infusion set from falling before entering the bag. When the infusion set enters the bag, the connection baffle 58 is at the same height as the lower support plate 56, so that the displacement bin 52 can smoothly move the infusion set into the packaging bag. A displacement induction switch 564 is also provided on the side of the connection side plate 519. A displacement induction hole 581 is made at the corresponding position of the connection baffle 58. The displacement induction switch 564 and the displacement induction hole 581 cooperate to sense whether a coiled infusion set is placed on the connection baffle 58. When the displacement induction switch 564 senses the infusion set, the displacement induction switch 564 sends a displacement instruction to the transfer drive motor 51.

[0072] In the above technical solution: As Figure 21As shown, the bag receiving device includes a bag opening suction cup 520, a front bag receiving cylinder 522, a rear bag receiving cylinder 526, a rear bag receiving backing plate 524 and a bag receiving bottom plate 528. The bag opening suction cup 520 is fixed on the lower suction cup fixing plate 521, and the lower suction cup fixing plate 521 is installed on the piston rod of the front bag receiving cylinder 522. A bag receiving lifting plate 525 is fixed to the bottom of the rear bag receiving backing plate 524, and the bag receiving lifting plate 525 is installed on the rear bag receiving cylinder 526. The bag opening suction cup 520 is used for receiving the bag. When the bag taking up and down mechanism sucks the packaging bag and moves it directly above the bag receiving device, the front bag receiving cylinder 522 drives the bag opening suction cup 520 to rise until the bag opening suction cup 520 sucks the packaging bag. At the same time, the rear bag receiving cylinder 526 drives the rear bag receiving backing plate 524 to rise. The rear bag receiving backing plate 524 provides a support point for the rear part of the packaging bag, making the packaging bag lie flat as much as possible, which is convenient for inserting the infusion set into the bag. After the bag opening suction cup 520 sucks the packaging bag, the front bag receiving cylinder 522 drives the bag opening suction cup 520 to descend slightly, so that a small opening is made in the packaging bag by the bag opening suction cup 520 until the opening device catches and opens the packaging bag, and then the bag opening suction cup 520 and the rear bag receiving backing plate 524 reset. A bag receiving fixing plate 523 is fixed to the back of the front bag receiving cylinder 522. The bag receiving fixing plate 523 is fixed to the bag receiving lifting plate 525. A bag receiving cushion block 527 is fixed below the rear bag receiving cylinder 526, and the bag receiving cushion block 527 is fixed on the bag receiving bottom plate 528.

[0073] In the above technical solution: the bag inserting mechanism includes a bag receiving rotating device and a rotating seat, as Figure 23As shown, the bag receiving and rotating device includes a bag receiving box 531 which is used to receive the packaging bags containing the coiled infusion sets transported by the shifting silo 52. On the upper and lower sides at the front end of the bag receiving box 531, there are fixed cylinder fixing plates 533. A suction cup cylinder 547 is installed on the cylinder fixing plate 533, and a bag receiving suction cup 530 is installed on the suction cup cylinder 547. The bag receiving suction cup 530 is driven by the suction cup cylinder 547 to hold the opening part of the packaging bag. At the rear end of the bag receiving box 531, there is fixed a jaw cylinder 535. Two rear pressing jaws 534 are connected to the jaw cylinder 535, and a rubber head pressing point 532 is installed at the end of the rear pressing jaw 534. A jaw groove 5312 is made at the corresponding position of the bag receiving box 531. When a packaging bag containing an infusion set is placed in the bag receiving box 531, the rear pressing jaw 534 is driven by the jaw cylinder 535 to press downwards, and the position where the rubber head pressing point 532 presses down is exactly at the center of the circle formed by coiling the infusion set, so as to position the infusion set and the packaging bag. Then, the shifting silo 52 is driven by the shifting mechanism to withdraw from the packaging bag and reset. Below the bag receiving box 531, there is fixed a rotation switch base 565. A rotation induction switch 566 is installed on the rotation switch base 565. A rotation induction hole 5311 is made at the corresponding position of the bag receiving box 531. The rotation induction switch 566 cooperates with the rotation induction hole 5311 to sense whether a packaging bag is received in the bag receiving box 531. When the rotation induction switch 566 senses the packaging bag, the rotation induction switch 566 sends an action instruction to the rotating base.

[0074] In the above technical solution: the rotating base includes a rotating shaft fixing plate 542 and a rotating cylinder 529. The rotating shaft fixing plate 542 is fixed on the workbench. Rotating right side plates 543 and rotating left side plates 541 are respectively installed at two ends of the rotating shaft fixing plate 542. A rotating shaft 545 is installed between the rotating right side plate 543 and the rotating left side plate 541. A rotating shaft bottom plate 546 is fixed on the rotating shaft 545. The bag receiving box 531 is fixed on the rotating shaft bottom plate 546. One end of the rotating shaft 545 passes through the rotating left side plate 541 and is hinged to one end of a rotating connecting rod 539. A rotating push pin 538 is installed at the other end of the rotating connecting rod 539. The rotating push pin 538 hinges the piston rod of the rotating cylinder 529 to the rotating connecting rod 539. The cylinder block of the rotating cylinder 529 is fixed on a rotating push rear seat 537. The rotating push rear seat 537 is fixed on the workbench through a rotating push fixing plate 536. The rotating cylinder 529 drives the rotating connecting rod 539 and the rotating shaft 545 to flip by 90°, so that the rotating shaft bottom plate 546 and the bag receiving rotating device are also driven to flip by 90°. A first rotating push buffer block 544 is also installed between the rotating right side plate 543 and the rotating left side plate 541. A second rotating push buffer block 540 is also installed on the rotating left side plate 541. Elastic members 568 are installed on both the first rotating push buffer block 544 and the second rotating push buffer block 540. The heads of the elastic members 568 have elasticity. When the rotating cylinder 529 drives the rotating connecting rod 539 to flip for feeding, the second rotating push buffer block 540 buffers the rotating connecting rod 539 through the elastic member 568 thereon. When the rotating cylinder 529 drives the rotating shaft bottom plate 546 and the bag receiving rotating device to flip and reset, the first rotating push buffer block 544 buffers the rotating shaft bottom plate 546 through the elastic member 568 thereon.

[0075] In the above technical solution: The shifting mechanism includes a shifting block 552, a shifting bottom plate 550, a moving drive motor 51 and a shifting synchronous belt 549. The shifting plate 548 fixes the shifting bin 52 on the shifting block 552. The shifting block 552 is in an inverted concave shape, including moving feet on both sides and a moving groove between the two moving feet. The bottom of the moving feet is provided with moving sliders 553, and the shifting bottom plate 550 is provided with moving slide rails 551. The moving sliders 553 cooperate with the moving slide rails 551. The two ends of the shifting bottom plate 550 are fixed with shifting bearing seats 558, and a shifting driving shaft 559 and a shifting driven shaft are respectively installed on the two shifting bearing seats 558. The shifting synchronous belt 549 is connected between the shifting driving shaft 559 and the shifting driven shaft. The shifting synchronous belt 549 passes through the moving groove and is fixed on the shifting block 552 by a belt pressing plate 557. A shifting detection plate 560 is installed on the side of the shifting block 552. The two ends of the side of the shifting bottom plate 550 are fixed with shifting stop switch seats 567, and a shifting stop switch 561 is installed on the shifting stop switch seats 567. When the shifting stop switch 561 contacts the shifting detection plate 560, it transmits a stop signal to the moving drive motor 51 to stop moving and prevent the shifting block 552 from moving excessively and damaging components. The bottom of the shifting bottom plate 550 is installed with a shifting adjustment block 554. Two parallel tensioning side plates 555 are installed on the shifting adjustment block 554, and a shifting tensioning wheel 556 is installed between the two tensioning side plates 555. The shifting tensioning wheel 556 cooperates with the shifting synchronous belt 549 to adjust the tension of the shifting synchronous belt 549, ensuring that the shifting synchronous belt 549 has an appropriate tension during the shifting process and avoiding slipping. The bottoms of the two ends of the shifting bottom plate 550 are fixed with shifting support plates 562, and the shifting support plates 562 are installed on the workbench through a jig support bottom plate 563.

[0076] In the above technical solution: As Figure 26 shown, several groups of the bagging and moving mechanisms 5 are arranged in parallel and are synchronously controlled by the same moving drive motor 51. A component connecting rod 569 is arranged between two adjacent bagging and moving mechanisms 5, and the moving drive motor 51 drives each shifting driving shaft 559 to rotate synchronously through the component connecting rod 569.

[0077] In the above technical solution: As Figures 27 - 32 shown, the packaging bag sealing mechanism 6 includes a transfer device, a bag transferring finger device, a bag transferring and shifting device and a sealing machine 654. The transfer device receives the packaging bag with an infusion set from the bag receiving and rotating device of the bagging and moving mechanism 5 and transfers it to the bag transferring finger device. The bag transferring finger device is driven by the bag transferring and shifting device to send the packaging bag to the sealing machine 654, and the packaging bag is sealed by the sealing machine 654 to complete the packaging.

[0078] In the above technical solution: as Figure 28 shown, the transfer device includes a lifting cylinder 61 and a horizontal pushing cylinder 63. The cylinder block of the lifting cylinder 61 is fixed on the transfer movable plate 619. The piston rod of the lifting cylinder 61 passes through the transfer movable plate 619 and is fixed on the bottom plate 69. A horizontal pushing cylinder joint 62 is fixed on the transfer movable plate 619. The piston rod of the horizontal pushing cylinder 63 is installed on the horizontal pushing cylinder joint 62. The cylinder block of the horizontal pushing cylinder 63 is fixed on the horizontal pushing cylinder seat 64. The horizontal pushing cylinder seat 64 is installed on the horizontal pushing fixed plate 65. A buffer seat 66 is installed on the horizontal pushing fixed plate 65. A buffer elastic member 623 is installed on the buffer seat 66. The buffer elastic member 623 cooperates with a buffer pad 67 on the side of the transfer movable plate 619. When the transfer movable plate 619 is driven by the horizontal pushing cylinder 63 to move horizontally, the buffer elastic member 623 and the buffer pad 67 play a role in limiting and buffering the contact collision of the transfer movable plate 619. A transfer slider 618 is also installed below the transfer movable plate 619. A transfer slide rail 659 is installed on the upper part of the bracket 9. The transfer slider 618 cooperates with the transfer slide rail 659 to facilitate the horizontal movement of the transfer device. Two guide rods 68 are provided on the transfer movable plate 619. The upper ends of the guide rods 68 pass through the transfer movable plate 619 and are fixedly connected to a guide rod connecting block 620, and the lower ends are fixed on the bottom plate 69. The guide rods 68 play a role in fixed connection. A transfer wire passing pipe 616 is also installed between the guide rod connecting block 620 and the bottom plate 69. A transfer cylinder 615 is installed at the bottom of the bottom plate 69. A finger clamping bottom plate 610 is connected below the transfer cylinder 615. A bag supporting cylinder 614 is fixed below the finger clamping bottom plate 610. Finger clamping limit blocks 611 are also installed at both ends of the finger clamping bottom plate 610. A limit elastic member 624 is installed on the finger clamping limit blocks 611. The piston rods at both ends of the bag supporting cylinder 614 are connected to a finger clamping fixed plate 612. A bag supporting finger 613 is installed on the finger clamping fixed plate 612. The bag supporting finger 613 cooperates with the packaging bag. When the bag supporting finger 613 extends into the packaging bag, the piston rod of the bag supporting cylinder 614 drives the bag supporting finger 613 to expand to both sides until it is limited by the limit elastic member 624. At this time, the bag opening of the packaging bag is just expanded to the maximum by the bag supporting finger 613, and the packaging bag is changed from being sucked by the bag receiving suction cup 530 to being clamped by the bag supporting finger 613. Then, the horizontal pushing cylinder 63 drives the transfer device to move towards the bag transferring device. After arriving, the transfer cylinder drives the packaging bag to rotate 90° to facilitate the bag transferring finger device to clamp it. A vacuum suction nozzle 617 is also installed below the bag supporting cylinder 614. The vacuum suction nozzle 617 is located between the bag supporting fingers 613. The vacuum suction nozzle cooperates with the packaging bag to evacuate the packaging bag to a vacuum state to prevent the infusion set from being infected.

[0079] In the above technical solution: As Figure 29 shown, the bag-transfer finger device includes finger components. There are two sets of the finger components, which are arranged oppositely. The finger components include bag-transfer fingers 621. An elastic rubber plate 622 is installed on one side of the bag-transfer fingers 621 opposite to each other. A bag-transfer side plate 625 is fixed below the bag-transfer fingers 621. The bag-transfer side plate 625 is installed on a bag-transfer clamping plate 627. A bag-clamping reinforcing rib 626 is fixed between the bag-transfer side plate 625 and the bag-transfer clamping plate 627. A bag-pressing adjustment block 629 is fixed on the bag-transfer clamping plate 627. A bag-transfer slider 631 is installed below the bag-transfer clamping plate 627. The bag-transfer slider 631 cooperates with a bag-transfer slide rail 632 on a bag-transfer finger bottom plate 630. A clamping connection block 633 is also fixed below the bag-transfer clamping plate 627. A finger cylinder 634 is installed below the bag-transfer finger bottom plate 630. Slider side plates 635 are fixed at both ends of the bag-transfer finger bottom plate 630. A finger cylinder groove is formed on the slider side plates 635. The piston rod of the finger cylinder 634 passes through the finger cylinder groove and is connected to the clamping connection block 633. When the bag-transfer finger device receives a bag, the piston rod of the finger cylinder 634 drives the clamping connection block 633 to move towards the middle. The bag-transfer clamping plate 627 and the bag-transfer fingers 621 are also driven to move towards the middle under the cooperation of the bag-transfer slider 631 and the bag-transfer slide rail 632 until the bag-transfer fingers 621 grab the packaging bag. A conveyor belt fixing block 636 is installed between the slider side plates 635. A conveyor belt upper pressing block 637 is installed below the conveyor belt fixing block 636. A slider fixing block 638 is also fixed below the slider side plates 635. A translation slider 639 is installed below the slider fixing block 638. A bag-transfer detection block 628 is also installed on the slider fixing block 638 on one side.

[0080] In the above technical solution: As Figure 30As shown in the figure, the bag transfer and displacement device includes a bag transfer bottom plate 642 and a lower drive bottom plate 646. A translation slide rail 650 is installed on the bag transfer bottom plate 642. The translation slide rail 650 cooperates with a translation slider 639 on the bag transfer finger device to facilitate movement. Three bag transfer switch seats 651 are also installed on the side of the bag transfer bottom plate 642. The bag transfer switch seats 651 are respectively located at the front and rear ends of the bag transfer bottom plate 642 and the position of receiving the bag in the middle. Bag transfer sensors 658 are provided on the three bag transfer switch seats 651. The bag transfer sensors 658 cooperate with a bag transfer detection block 628 on the bag transfer finger device. Displacement bearing seats are fixed at both ends of the bag transfer bottom plate 642. A bag transfer driving shaft 643 and a bag transfer driven shaft 649 are respectively installed on the displacement bearing seats. A second conveyor belt 640 is connected between the bag transfer driving shaft 643 and the bag transfer driven shaft 649. The second conveyor belt 640 is fixed on a conveyor belt fixing block 636 through a conveyor belt upper pressing block 637. A bag transfer tensioning block 655 is also installed at the bottom of the bag transfer bottom plate 642. Two parallel bag transfer tensioning side plates 656 are installed on the bag transfer tensioning block 655. A bag transfer tensioning wheel 657 is installed between the two bag transfer tensioning side plates 656. The bag transfer tensioning wheel 657 cooperates with the second conveyor belt 640. The bag transfer tensioning wheel 657 is used to adjust the tightness of the second conveyor belt 640 to ensure that the second conveyor belt 640 has an appropriate tension during transmission to avoid slipping. One end of the bag transfer driving shaft 643 passes through the displacement bearing seat and is connected to a first conveyor belt 641. The other end of the first conveyor belt 641 is connected to a lower drive shaft 645 below the lower drive bottom plate 646. Displacement bearing seats are fixed below the lower drive bottom plate 646. The lower drive shaft 645 is installed between the displacement bearing seats. One end of the lower drive shaft 645 passes through the displacement bearing seat and is installed with a conveyor belt motor 652. The conveyor belt motor 652 is fixed by a conveyor belt motor fixing seat 653. A drive limit block 647 is also installed at the tail of the lower drive bottom plate 646. The drive limit block 647 is connected to a drive adjustment block 648. The bag transfer and displacement device is responsible for driving the bag transfer finger device to move to receive the bag and send it to a sealing machine 654. The specific transmission process is as follows: The conveyor belt motor 652 starts to operate, driving the lower drive shaft 645 to rotate. The first conveyor belt 641 transmits the rotational movement to the bag transfer driving shaft 643, and thus the second conveyor belt 640 starts to move. Since the bag transfer finger device is fixed on the second conveyor belt 640 by the conveyor belt fixing block 636 and the conveyor belt upper pressing block 637, the second conveyor belt 640 drives the bag transfer finger device to move under the cooperation of the translation slider 639 and the translation slide rail 650.After the bag transfer sensor 658 comes into contact with the bag transfer detection block 628, the bag transfer sensor 658 transmits a stop command to the bag transfer motor 652. The bag transfer sensors 658 at the front and rear ends limit the moving distance of the bag transfer finger device on the bag transfer bottom plate 642, and the bag transfer sensor 658 in the middle controls the bag transfer finger device to stop moving and cooperate with the transfer device to receive the bag.

[0081] In the above technical solution: several groups of the packaging bag sealing mechanisms are provided and arranged in parallel. For example, Figure 31 as shown, the transfer devices are fixed by an intermediate connection block 660 and are translated by the same flat push cylinder 63. As Figure 32 shown, Figure 32 To more clearly show the overall structure, only the three-dimensional structure diagram when two groups of bag transfer finger devices and bag transfer displacement devices are arranged in parallel is shown. A bag transfer component connecting rod 661 is arranged between two adjacent bag transfer displacement devices, and the bag transfer motor 652 drives each bag transfer displacement device to move synchronously.

[0082] The working process of the present invention is as follows. First, an operator places the infusion set on the infusion set fixture of the feeding and loading mechanism 1. When feeding, the flat placement mechanism and the infusion set fixture are in a vertical state. First, the head of the puncture part of the infusion set abuts against the top block 13, and the tail is clamped into the infusion set positioning block 14. Since a plunger screw 143 is installed on the infusion set positioning block 14, when the infusion set is clamped into the U-shaped groove 142, the ball 1431 protruding from the inner surface of the U-shaped groove 142 is squeezed, and the spring 1433 is compressed. The ball 1431 retracts into the plunger screw hole. When the infusion set enters the U-shaped groove 142, the ball 1431 is no longer squeezed, and the spring 1433 elastically releases. The ball 1431 returns to the state of protruding from the inner surface of the U-shaped groove 142 and plays a positioning role for the infusion set in the U-shaped groove 142 to prevent it from falling off during the loading process. At the same time, the tail of the drip chamber is also clamped into the drip chamber block 15 in the same way as the tail of the puncture part of the infusion set cooperates with the infusion set positioning block 14, and the middle part of the catheter is located in the catheter groove of the catheter block 16, and the remaining part of the catheter naturally hangs down. At this time, the cooperation between the infusion set and the infusion set fixture is completed, that is, the feeding is completed.

[0083] Next, under the action of the swing cylinder 11, the horizontal placement mechanism rotates clockwise by 90° around the horizontal placement rotation shaft 122 until the horizontal placement bottom plate 18 is limited by the first positioning stop nut 118. The specific limiting process is that the horizontal placement bottom plate 18 slowly presses down the cap head of the first positioning stop nut 118 until the cap head is fully retracted into the nut, and the horizontal placement bottom plate 18 is limited by the nut and stops moving. At this time, the horizontal placement mechanism is in the horizontal feeding state. After the feeding component of the material taking and shifting mechanism 2 takes away the infusion set, the horizontal placement mechanism is driven by the swing cylinder 11 to rotate counterclockwise by 90° around the horizontal placement rotation shaft 122 to reset, and the vertical limiting block 121 is also driven to rotate together until the vertical limiting block 121 is limited by the second positioning stop nut 120. At this time, the horizontal placement mechanism returns to the vertical state for manual feeding, and the feeding is completed.

[0084] After the feeding and loading are completed, the translation cylinder 21 drives the feeding component of the material taking and shifting mechanism 2 to move directly above the loading mechanism. Then, the feeding cylinder 22 drives the first clamping device to descend. When it descends to a certain position, the front clamping jaw cylinder 210 drives the front jaw support 212 to open, so that the two front clamping jaws 213 are separated from each other, and the right rear clamping jaw 214 and the left rear clamping jaw 215 are also separated from each other. The rear clamping jaw cylinder 211 also drives the two air pipe clamping jaws 216 to open. When the first clamping device descends to a certain position, the front clamping jaw cylinder 210 and the rear clamping jaw cylinder 211 drive the first clamping device to close and clamp the infusion set. At this time, the puncture device of the infusion set is located in the puncture device fixing block 2131 of the front clamping jaw 213, the end of the catheter is located in the catheter fixing block formed by the cooperation of the left rear clamping jaw 215 and the right rear clamping jaw 214, and the middle part of the catheter is clamped in the air pipe clamping jaws 216. After clamping the infusion set, the feeding cylinder 22 drives the first clamping device to rise and reset. The translation cylinder 21 drives the feeding component to move directly above the tube winding mechanism 3. Then, the feeding cylinder 22 drives the first clamping device to descend. After the first clamping device descends to a certain position, the front clamping jaw cylinder 210 and the rear clamping jaw cylinder 211 drive the first clamping device to open, so that the infusion set slowly falls onto the rotating jig of the tube winding mechanism 3. Finally, the feeding cylinder 22 drives the first clamping device to rise and reset.

[0085] The infusion set is fixed by the fixing device of the tubing winding mechanism 3. The specific fixing method is as follows: The tail of the drip chamber of the infusion set is clamped between the drip chamber stopper groups 314. The catheter of the infusion set extends out between the two second stoppers 3151 and hangs on the front guide plate 318. The swing cylinder 330 drives the chute movable baffle 319 to rotate a certain angle through the stopper swing block 322 and the chute rotating shaft 327, so that the chute movable baffle 319 and the chute left baffle 320 cooperate to press the catheter part of the infusion set. After the infusion set is fixed, the rotation drive motor 31 drives the rotation fixture to rotate synchronously. Under the action of the limiting device, the catheter of the infusion set is wound around the periphery of the catheter stopper group 315 into an approximately elliptical shape. The specific cooperation mode between the limiting device and the catheter of the infusion set is: When winding the tubing, the needle-shaped cylinder 325 drives the elastic stopper 317 to make it closely follow the rotating infusion set and swing, that is, the catheter of the infusion set is continuously resisted by the elastic stopper 317 during the rotation process and cannot be thrown outwards, and can only be wound around the periphery of the catheter stopper group 315 into an approximately elliptical shape while rotating. After the catheter is wound, the rotation drive motor 31 and the needle-shaped cylinder 325 stop moving. The pulling force of the tension spring 326 causes the elastic stopper 317 to quickly reset after the swing stops. The shifting component of the material taking and shifting mechanism 2 descends until it touches the surface of the rotating disk 311. At the same time, the telescopic cylinder 323 drives the fixing device to descend along the lifting guide rod 38 through the lifting bottom plate 39 until the fixing device is lower than the surface of the rotating disk 311. Subsequently, the shifting component drives the wound infusion set to move into the shifting bin 52. The telescopic cylinder 323 drives the fixing device to rise and reset along the lifting guide rod 38 through the lifting bottom plate 39, and the tubing winding is completed.

[0086] The action process of the shifting component of the material taking and shifting mechanism 2 moving the wound infusion set is as follows: The translation cylinder 21 drives the shifting component to move directly above the rotation fixture. The material extraction cylinder 25 drives the second clamping device to descend and cooperate with the wound infusion set. The cooperation mode between the second clamping device and the wound infusion set is specifically as follows: The material extraction stoppers 218 at both ends of the material extraction adjustment plate 217 extend into the wound infusion set and just clamp the two ends of the wound infusion set, while the material extraction pressing column 219 presses the catheter part of the wound infusion set. The semi-circular groove of the material extraction middle stopper 220 clamps the drip chamber part of the infusion set. Then the shifting component moves horizontally together with the translation cylinder 21 until the second clamping device pushes the wound infusion set into the shifting bin 52. Then the material extraction cylinder 25 drives the second clamping device to rise and reset. The second clamping device directly exits the shifting bin 52 from the observation port, and the infusion set is stuck by the observation port and remains in the shifting bin 52.

[0087] While the infusion set is displaced by being wound around, the bag loading mechanism 4 starts to pick up and transfer bags. The bag picking cylinder 44 starts to actuate and drives the bag picking suction cup assembly to move downward to pick up materials. The specific process of the bag picking suction cup assembly for picking up materials is as follows: After the bag picking suction cup 412 touches the packaging bag, the bag picking cylinder 44 continues to drive the bag picking suction cup assembly to move downward a certain distance, so that the suction head part of the bag picking suction cup 412 is subjected to a certain extrusion and the air between the bag picking suction cup 412 and the packaging bag is discharged. At this time, the bag picking suction cup 412 sucks the packaging bag by the vacuum effect. Subsequently, the bag picking cylinder 44 drives the bag picking suction cup assembly to rise, and the bag transfer slider 45 cooperates with the bag transfer slide rail 427 to drive the bag picking up and down mechanism to be moved by the outer pushing cylinder 429 to directly above the bag receiving device of the bag inserting and transferring mechanism 5. Then the bag picking cylinder 44 drives the bag picking suction cup assembly to descend and cooperate with the bag receiving device. If the sensors on both sides of the packaging bag feeding slot 41 cannot sense the packaging bag, the sensors receive the signal and start the micro AC reduction motor 425. The micro AC reduction motor 425 drives the screw rod 424 to move through the coupling 423, so that the support rod bottom plate 417 rises along the screw rod 424 under the cooperation of the nut 426, and thus the packaging bag in the packaging bag feeding slot 41 is driven by the feeding slot support rod 416 to move upward until the sensors sense the packaging bag, and the micro AC reduction motor 425 stops running.

[0088] The specific cooperation mode between the bag picking suction cup assembly and the bag receiving device is as follows: Before bag receiving, the cylinder 522 drives the bag opening suction cup 520 to rise. After bag receiving, the cylinder 526 drives the post-bag receiving backing plate 524 to rise through the bag receiving lifting plate 525. The rising degree of the cylinder 522 before bag receiving is greater than that of the cylinder 526 after bag receiving, that is, when receiving the bag, the bag opening suction cup 520 is higher than the post-bag receiving backing plate 524, so that the post-bag receiving backing plate 524 always plays a certain supporting role on the rear part of the packaging bag. After the bag picking suction cup 412 on the bag loading mechanism 4 sucks the packaging bag and moves it directly above the bag receiving device, the bag opening suction cup 520 contacts the packaging bag and sucks the packaging bag. Then the cylinder 526 after bag receiving drives the post-bag receiving backing plate 524 to retract, and the cylinder 522 before bag receiving drives the bag opening suction cup 520 to slightly descend so that a small opening is formed between the head of the packaging bag by the bag opening suction cup 520 and the bag picking suction cup 412.

[0089] Subsequently, the opening device fully opens the head of the packaging bag. The opening cylinder 57 drives the lower support plate 56 to move upward by a certain distance. Then, the bag receiving cylinder 517 drives the upper support plate 53 and the lower support plate 56 to move backward to the front of the bag receiving device. The upper support plate 53 and the lower support plate 56 extend into the packaging bag. The opening cylinder 57 drives the lower support plate 56 to move downward and reset to the same height as the connection baffle 58. At this time, the head of the packaging bag is also fully opened by the upper support plate 53 and the lower support plate 56. While the packaging bag is being opened by the opening device, the packaging bag feeding mechanism resets, and the pre-bag receiving cylinder 522 retracts. At this time, the lower suction cup fixing plate 521 resets to the same height as the bag receiving lifting plate 525, so that the bag opening suction cup 520 does not interfere with the operation of other components. Then, the bag receiving cylinder 517 acts and drives the opening device to reset.

[0090] Then, the infusion set enters the bag. When the opening device opens and resets the packaging bag, the shifting mechanism moves the wound infusion set to the shifting bin 52 and directly above the U-shaped notch of the shifting bin 52. The U-shaped notch is blocked by the connection baffle 58 to prevent the infusion set from falling. At this time, the lower support plate 56 is also at the same height as the connection baffle 58, which is convenient for the infusion set to enter the bag. After the shifting induction switch 564 senses the infusion set on the connection baffle 58, it starts the moving drive motor 51. The moving drive motor 51 drives the shifting driving shaft 559 to rotate, and thus the shifting synchronous belt 549 starts to move. Since the belt pressing plate 557 fixes the shifting synchronous belt 549 on the shifting block 552, and the shifting bin 52 is fixed on the shifting block 552, the shifting synchronous belt 549 drives the shifting bin 52 to shift synchronously. The shifting bin 52 moves the wound infusion set into the packaging bag opened by the opening device and continues to drive the packaging bag to move forward together until the shifting detection plate 560 on the shifting block 552 touches the shifting stop switch 561. The shifting stop switch 561 receives the signal and sends an instruction to stop the operation to the moving drive motor 51. At this time, the shifting bin 52 just moves the packaging bag into the bag receiving box 531 of the bagging mechanism.

[0091] Then, the bagging mechanism drives the packaging bag to rotate 90°. After the bag receiving box 531 receives the bag, the bag receiving suction cup 530 is driven by the suction cup cylinder 547 to move towards the packaging bag and suck the upper and lower sides of the head of the packaging bag. At the same time, after the rotation induction switch 566 senses the packaging bag in the bag receiving box 531, it starts the jaw cylinder 535. The jaw cylinder 535 drives the rear pressing jaw 534 to press towards the middle through the jaw slot 5311, the observation port and the U-shaped notch of the shifting bin 52. The position where the rubber head pressing point 532 presses is exactly at the center of the circle formed by winding the infusion set, so as to position the infusion set and the packaging bag. Then, the shifting bin 52 is driven by the moving drive motor 51 to withdraw from the packaging bag and reset. Then, the rotating cylinder 529 drives the rotating link 539 and the rotating shaft 545 to flip 90°, so that the rotating shaft bottom plate 546 and the bag receiving rotating device are also driven to flip 90°.

[0092] After the infusion set is turned over and put into the bag, the packaging bag then passes through the transfer mechanism of the packaging bag sealing mechanism 6 for bag transfer. The lifting cylinder 61 starts to act and drives the bag-supporting clamp fingers 613 to descend to receive the bag. The specific bag-receiving process is as follows: The end of the bag-supporting clamp fingers 613 extends into the interior of the packaging bag, and the piston rod of the bag-supporting cylinder 614 drives the bag-supporting clamp fingers 613 to slowly open until they are limited by the limiting elastic member 624 and stop moving. At this time, the open state of the bag-supporting clamp fingers 613 just opens the bag mouth of the packaging bag to the maximum, making the bag mouth of the packaging bag flat and able to be supported by the bag-supporting clamp fingers 613 without falling. While the bag-supporting clamp fingers 613 receive the bag, the vacuum suction nozzle 617 evacuates the packaging bag to a vacuum. Subsequently, the flat-pushing cylinder 63 drives the entire transfer device and the packaging bag to translate to one side of the bag-transfer bottom plate 642, and the transfer cylinder 615 drives the lower bag-supporting clamp fingers 613 and the packaging bag to rotate 90°, making the packaging bag parallel to the bag-transfer bottom plate 642 and exactly located on the center line of the bag-transfer bottom plate 642 for the bag-transfer clamp finger device to pick up the material.

[0093] Then the bag-transfer clamp finger device clamps the packaging bag, and the bag-transfer displacement device is responsible for driving the bag-transfer clamp finger device to move to receive the bag and send it to the sealing machine 654. The specific transmission process is as follows: The conveyor belt motor 652 starts to act, and the lower transmission shaft 645 is driven to rotate. The first conveyor belt 641 transmits the rotational motion to the bag-transfer driving shaft 643, so that the second conveyor belt 640 starts to move. Since the bag-transfer clamp finger device is fixed to the second conveyor belt 640 by the conveyor belt fixing block 636 and the conveyor belt upper pressing block 637, the bag-transfer clamp finger device is driven by the second conveyor belt 640 to move under the cooperation of the translation slider 639 and the translation slide rail 650. When the bag-transfer sensor 658 in the middle of the bag-transfer bottom plate 642 contacts the bag-transfer detection block 628, the bag-transfer sensor 658 transmits a stop command to the conveyor belt motor 652, and the bag-transfer clamp finger device stops moving. At this time, the packaging bag clamped by the bag-supporting clamp fingers 613 is exactly located between the two bag-transfer clamp fingers 621. Then the piston rod of the clamp finger cylinder 634 drives the clamping connection block 633 to move towards the middle, and the two bag-transfer clamp fingers 621 and the bag-transfer clamping plate 627 are driven to move towards the middle together until the two bag-transfer clamp fingers 621 firmly clamp the packaging bag clamped by the bag-supporting clamp fingers 613. Then the piston rod of the bag-supporting cylinder 614 drives the bag-supporting clamp fingers 613 to reset, and the transfer device resets. At the same time, the conveyor belt motor 652 continues to drive the bag-transfer clamp finger device and the packaging bag to move on the bag-transfer bottom plate 642 through the second conveyor belt 640. When the bag-transfer detection block 628 contacts the bag-transfer sensor 658 near one end of the bag-transfer driven shaft 649, the bag-transfer sensor 658 transmits a stop command to the conveyor belt motor 652, and the bag-transfer clamp finger device stops moving. At this time, the packaging bag just enters the sealing machine 654. The piston rod of the clamp finger cylinder 634 drives the bag-transfer clamp fingers 621 to slowly move towards both sides. After releasing the packaging bag, the bag-transfer displacement device is driven by the conveyor belt motor 652 to retreat and reset, and the packaging bag is sealed in the sealing machine 654 to complete the packaging.
