Suction tubes are medical consumables, which are in great demand and need to be manufactured and used in large quantities. The existing processing and assembly of suction tubes is generally divided into multiple processes and the multiple processes are completely separated. At the same time, as medical consumables, the more processes there are, the more difficult it is to control the contamination of the product. At the same time, the transfer of suction tubes between different processes also consumes too much time and economic costs. Therefore, an efficient and low-cost manufacturing method is required; the suction tube assembly machine of the present invention realizes mechanized operation from entering the suction tube body to completing the installation and punching of the connector without any pause in between; the installation and punching mechanism 400 can simultaneously install and punch the connectors at both ends of the suction tube body, effectively improving work efficiency; the integrated processing machinery can solve the transfer of suction tubes between different processing equipment, reduce labor costs and time costs, and improve work efficiency; at the same time, it reduces the pollution problems that may be caused by the suction tube during the transfer process.

[0037] In some embodiments of the present invention, the transmission mechanism 200 includes a transmission belt 210, a driving motor 220 and a driving shaft 240. The output shaft of the driving motor 220 is connected to the driving shaft 240 by transmission. The transmission belt 210 is connected to the driving shaft 240 by transmission. The rotation of the driving motor 220 drives the driving shaft 240 to rotate, thereby driving the transmission belt 210 to move in one direction. The outer surface of the transmission belt 210 is provided with a slot 250, and the slot 250 is used to clamp the suction tube body to limit it. Specifically, as Figure 6As shown, there are multiple conveyor belts 210, and the multiple conveyor belts 210 are arranged at intervals along the connecting line direction of the connecting device and the punching device 402. The driving shaft 240 is penetrated by the multiple conveyor belts 210, and the driving shaft 240 is provided with multiple gears, and the multiple gears are respectively engaged with the multiple conveyor belts 210 for transmission; the transmission mechanism 200 also includes a driving belt 230, and the driving shaft 240 is also provided with a driving gear. The output shaft of the driving motor 220 is connected to the driving gear through the driving belt 230, and the driving gear is fixedly connected to the driving shaft 240. The driving motor 220 rotates and then drives the driving shaft 240 through the driving belt 230 to select, thereby driving the conveyor belt 210 to move in a single direction. The outer surface of the conveyor belt 210 is provided with multiple slots 250, and the slots 250 are provided with grooves consistent with the outer diameter of the suction tube. The suction tube is placed in the slots 250 of the conveyor belt 210, and the suction tube can be limited to prevent the suction tube from slipping off the conveyor belt 210 during transmission.

[0038] In some embodiments of the present invention, the hose supply device 301 includes a hose reel 310, a guide wheel 320 and a sliding tube feeder 340. The suction tube body wound on the hose reel 310 is fed to the sliding tube feeder 340 through the guide wheel 320. The sliding tube feeder 340 clamps the end of the suction tube body fed by the guide wheel 320 and drives it to move horizontally. The sliding tube feeder 340 is provided with a device for cutting off the suction tube body. Specifically, Figure 1 , Figure 2 As shown, the hose reel 310 is used to wind a continuous long suction tube body thereon, and the hose reel 310 can be replaced as a whole. When the suction tube body on a hose reel 310 is used up, another new hose reel 310 with the suction tube body wound around it can be used to replace it, and the overall replacement is more convenient and quick. A longer suction tube body is arranged between the hose reel 310 and the guide wheel 320 to reduce the resistance of the sliding tube feeder 340 to pull and prevent the sliding tube feeder 340 from pulling the hose too fast to damage the equipment.

[0039] In some embodiments of the present invention, the sliding tube feeder 340 is disposed above the rotating device 302, and includes a tube cutter 330, a sliding frame 341 and a first finger cylinder 342. The tube cutter 330 is disposed at one end of the sliding tube feeder 340 close to the guide wheel 320, and the first finger cylinder 342 is installed on the sliding frame 341. The first finger cylinder 342 is connected to a driving device that drives it to slide horizontally along the sliding frame 341. After the first finger cylinder 342 clamps the end of the suction tube body and slides to the end of the sliding frame 341, the rotating device 302 clamps the suction tube body, and the tube cutter 330 cuts off the suction tube body. Specifically, as Figure 3As shown, the first finger cylinder 342 can be opened or closed to clamp the end of the suction tube, and is connected to a pneumatic drive device to drive it to slide along the sliding frame 341. The tube shearing machine 330 is provided with shear blades 331, and two shear blades 331 are arranged on both sides of the suction tube body, and are connected to a cylinder that can drive the two to close; after the first finger cylinder 342 slides to the end of the sliding frame 341, the rotating device 302 will clamp the suction tube body located above it, and at this time, the two shear blades 331 will close to cut off its connection with the entire suction tube long hose, leaving the suction tube body of the rated length for the next step of processing.

[0040] In some embodiments of the present invention, Figure 5 As shown, the rotating device 302 is provided with a turntable 350 and a second finger cylinder 360. The second finger cylinder 360 is provided on the turntable 350 and is used to clamp the suction tube body supplied by the sliding tube feeder 340. There are two turntables 350, which are arranged in parallel and spaced apart. The middle of the two turntables 350 is rigidly connected. The two ends of the turntable 350 are connected to the first rotating motor 352 for driving the rotation thereof. The turntable 350 is provided with a second finger cylinder 360. The second finger cylinder 360 is provided with two pairs, one turntable 350 is provided with a pair, and the finger clamping ends of the pair of second finger cylinders 360 are away from each other and extend out of the turntable 350. The first rotating motor 352 rotates 180 degrees each time, so that the second finger cylinder 360 is turned upside down. Since there are two pairs, each flip of the first rotating motor 352 can ensure that there are two second finger cylinders 360 above the turntable 350 for clamping the suction tube body. When the first finger cylinder 342 slides along the sliding frame 341, the two second finger cylinders 360 facing upwards on the two turntables 350 are both in an open state, so that the second finger cylinder 360 will not interfere with the first finger cylinder 342; the first finger cylinder 342 clamps the suction tube body and passes it between the two opened second finger cylinders 360. After the first finger cylinder 342 reaches the end of the sliding frame 341, the two second finger cylinders 360 facing upwards close together to clamp the suction tube body placed therein. At this time, the tube cutter 330 cuts off the continuity between the suction tube body clamped by the rotating device 302 and the overall hose, and then the turntable 350 rotates to rotate the second finger cylinders 360 facing upwards to the bottom to supply them to the clamping and feeding device 303; the first clamping finger quickly slides back toward the direction of the tube cutter 330 during the rotation of the turntable 350. The rotating device 302 further includes a guide hole platform 351, which is disposed on one side of the tube shear 330 close to the guide wheel 320. The suction tube hose enters the guide hole platform 351 from the guide wheel 320 and is then sent to the clamping position of the first finger cylinder 342. The guide hole platform 351 is provided with a hole for the suction tube body to pass through, and the guide hole platform 351 can make the suction tube body in a straight state after passing through the hole.

[0041] In some embodiments of the present invention, the clamping device 303 includes a third finger cylinder 370, a horizontal telescopic cylinder 371 and a vertical telescopic cylinder 372, the vertical telescopic cylinder 372 is installed on the frame 100, the horizontal telescopic cylinder 371 is arranged on the vertical telescopic cylinder 372, and the third finger cylinder 370 is arranged on the horizontal telescopic cylinder 371. Figure 4 As shown, after the turntable 350 rotates to drive the suction tube body to rotate downward, the vertical telescopic gas rod extends upward, the horizontal telescopic cylinder 371 extends toward the direction of the conveyor belt 210, and the third finger cylinder 370 opens; after reaching the position of the suction tube body, the third finger cylinder 370 closes and clamps the two ends of the suction tube body clamped by the second finger cylinder 360, the second finger cylinder 360 opens, and the vertical telescopic cylinder 372 descends; then the horizontal telescopic cylinder 371 continues to extend toward the conveyor belt 210, and after reaching above the conveyor belt 210, the vertical telescopic cylinder 372 continues to descend, the third finger cylinder 370 opens, and the clamped suction tube body is placed on the conveyor belt 210. After the second finger cylinder 360 releases the suction tube body it clamps, the turntable 350 can start to rotate due to the descent of the vertical telescopic cylinder 372. After the third finger cylinder 370 places the suction tube body on the conveyor belt 210, the vertical telescopic cylinder 372 moves upward a short distance, and then the horizontal telescopic cylinder 371 retracts, and the third finger cylinder 370 remains in the open state until the next clamping.

[0042] In some embodiments of the present invention, the connecting device 401 includes a sliding finger clamp 430 and a glue applicator 440. The sliding finger clamp 430 is used to clamp the connecting head and drive it to slide to a connection position with the suction tube body; the glue applicator 440 is used to apply glue and limit one end of the suction tube body.

[0043] In some embodiments of the present invention, the connection device 401 further includes a joint slide rail 410 and a stopper 420. One end of the joint slide rail 410 is connected to a feeding device for supplying a joint head. A sliding finger clamp 430 is provided at the other end of the joint slide rail 410 to clamp the joint head that slides out of the joint slide rail 410. The stopper 420 is provided between the joint slide rail 410 and the sliding finger clamp 430 to limit the joint head that slides out of the joint slide rail 410. Specifically, as Figure 7As shown, one end of the joint slide rail 410 is used for feeding, and the joint slide rail 410 is inclined, the connector slides in from one end of the joint slide rail 410 and slides out from the other end. After sliding out, it is clamped by the sliding finger clamp 430 and drives the connector to move for connection with the suction tube; because the sliding finger clamp 430 slides back and forth, it is necessary to wait for one connector to be sent out before sliding out the next connector for the sliding finger clamp 430 to clamp; when the sliding finger clamp 430 drives the connector to slide, the limiter 420 is used to limit the subsequent connector from sliding out; when the sliding finger clamp 430 is located at the end of the joint slide rail 410 to clamp the connector, the limiter 420 is used to limit the connector to a position for the sliding finger clamp 430 to clamp.

[0044] In some embodiments of the present invention, the joint rail 410 includes a chute tube 411 and a reversing disk 412. Two chute tubes 411 are provided and arranged in the same straight line. The reversing disk 412 is provided between the two chute tubes 411 and can reverse the direction of the connectors entering therein to ensure that the connectors entering the next chute tube 411 are all in the same direction. Specifically, the connector has directionality and is not consistent at both ends, so it must be ensured that the same end of the connector is connected to the sputum suction tube. The connector has radially protruding air holes, and the air holes are connected to a plug. The upper surface of the chute tube 411 is provided with a gap for the connector to slide along the axial direction, and the protruding air holes and the plug of the connector are exposed from the chute tube 411. A direction sensor 413 is provided on one side of the reversing disk 412. The direction sensor 413 is used to detect the position of the plug of the connector. When it is detected that the orientation of the plug is inconsistent with the required orientation of the connector, the direction sensor 413 sends a signal to the reversing disk 412, and the reversing disk 412 will rotate one hundred and eighty degrees so that all connectors used to connect to the suction tube are in the same orientation.

[0045] It is understandable that the supply device for supplying the connectors may be controlled so that the connectors entering the connector slide rail 410 are all oriented in the same direction.

[0046] In some embodiments of the present invention, the stopper 420 includes a rotating cylinder 421, a rotating arm 422 and a rotating horizontal bar 423. The rotating horizontal bar 423 is provided with two, which are respectively arranged at the two ends of the rotating arm 422. The middle part of the rotating arm 422 is installed on the rotating cylinder 421. The rotating cylinder 421 can drive the rotating arm 422 to rotate, thereby driving the two rotating horizontal bars 423 to alternately extend into the output path of the connector. Figure 1 , Figure 7As shown, one end of the slide groove tube 411 close to the sliding finger clamp 430 is provided with a sliding path extending outward, and the rotating horizontal bar 423 extends into this sliding path; when the rotating arm 422 rotates, the interval between the two rotating horizontal bars 423 is just enough to allow a single connector to pass through. On the other side of the slide tube 411 relative to the limiter 420, a first sensor 424 is provided. The first sensor 424 is used to detect the sliding finger clamp 430. When the first sensor 424 detects that the sliding finger clamp 430 is located at the end of the slide tube 411, the rotating arm 422 drives the rotating horizontal bar 423 near the end of the sliding finger clamp 430 to extend into the output path of the connector, preventing the connector from sliding out of the slide tube 411, and the rotating horizontal bar 423 near the end of the joint slide rail 410 is retracted; after the fourth finger cylinder 431 clamps the connector, the rotating arm 422 drives the rotating horizontal bar 423 near the end of the joint slide rail 410 to extend into the output path of the connector, and the rotating horizontal bar 423 near the sliding finger clamp 430 is retracted. The action is simple, efficient and not prone to errors.

[0047] In some embodiments of the present invention, the sliding finger clamp 430 includes a first slide 432, a first slide seat 433 and a fourth finger cylinder 431. The first slide 432 is installed on the frame 100, and the first slide seat 433 is installed on the first slide 432, and is connected to a driving device that can drive it to slide along the first slide 432; the driving device is a pneumatic device, which drives the first slide 432 to slide along the first slide seat 433 through airflow. The fourth finger cylinder 431 is arranged at the end of the first slide seat 433, and is used to clamp the connector that slides out from the joint slide rail 410; when the first slide seat 433 slides, it can drive the connector clamped by the fourth finger cylinder 431 to slide to the connection position with the suction tube. Specifically, as Figure 8 As shown, a clamping finger is provided at the end of the fourth finger cylinder 431, which can open and close to clamp the connector. After the glue coating machine 440 limits the glue coating on the end of the suction tube, the fourth finger cylinder 431 slides with the first slide seat 433 to the connection position with the end of the suction tube, and the connector is inserted into the end of the suction tube.

[0048] In some embodiments of the present invention, the glue coating machine 440 includes a sponge box 441, a hose connector 442 and a first telescopic cylinder 443. The sponge box 441 is provided with a sponge. The hose connector 442 is provided in the sponge box 441 and is used to connect with the glue box to supply glue to the sponge in the sponge box 441. The sponge box 441 is provided at the end of the first telescopic cylinder 443. The two sponge boxes 441 are relatively arranged on both sides of the end of the connecting pipe. The two first telescopic cylinders 443 can move toward each other, thereby driving the two sponge boxes 441 to close. Specifically, the two opposite surfaces of the two sponge boxes 441 are in an open state, the sponge is arranged in the box body and partially extends out of the box body; the sponge box 441 is also provided with a semicircular groove. When the two sponge boxes 441 are closed, a hole for the suction tube to pass through is formed in the middle of the two semicircular grooves. The two sponge boxes 441 limit the end of the suction tube to the hole formed by the two semicircular grooves, and the sponge in the sponge box 441 applies glue to the outer peripheral wall of the end of the suction tube.
