[0027] like Figure 1-6As shown, in the embodiment, a high-speed horizontal medical device braiding machine is provided, including a protective shell 1, on which an unwinding mechanism 2, a braiding mechanism 3, a traction mechanism 4 and a winding mechanism 5 are arranged from left to right, the braiding mechanism 3 includes a bottom box 31, a braiding power motor 32, a dial 33, a running spindle 34 and a lubrication module 35, the bottom box 31 is vertically arranged on the inner wall of the protective shell 1, a braiding power motor 32 is arranged on one side of the bottom box 31 close to the unwinding mechanism 2, and an annular groove 311 is arranged on the other side of the bottom box 31, and more than two dials 33 are evenly arranged in the annular groove 311. 3, a running spindle 34 is connected to the dial 33, a transmission gear is also arranged in the bottom box 31, the weaving power motor 32 drives the dial 33 to operate through the transmission gear, the lubrication module 35 includes a heat collecting block 351, a heat bending sheet 352 and a sponge oil absorbing block 353, a groove 312 is arranged on the side wall of the annular groove 311, a heat collecting block 351 is arranged in the groove 312, and the end face of the heat collecting block 351 is flush with the side wall of the annular groove 311, a heat bending sheet 352 is arranged at the other end of the heat collecting block 351, and a sponge oil absorbing block 353 is arranged on the heat bending sheet 352, and a control panel 6 is arranged on the protective shell 1. In this embodiment, the unwinding mechanism 2 and the rewinding mechanism 5 are respectively arranged on the left and right sides of the protective shell 1, the weaving mechanism 3 and the traction mechanism 4 are arranged inside the protective shell 1, and the protective shell 1 can protect the internal components and reduce the impact of the external environment (such as dust pollution). The structures of the unwinding mechanism 2 and the rewinding mechanism 5 are both existing technologies and will not be repeated here. A core wire is wound on the unwinding mechanism 2, and the rolled yarn is installed on the running spindle 34. The weaving mechanism 3 can weave the yarn on the surface of the core wire to form a weaving wire. The traction mechanism 4 can pull the weaving wire to one side to achieve simultaneous tensioning of the core wire and the yarn, thereby ensuring the weaving quality and realizing continuous weaving operations. The winding mechanism 5 is used to wind up the weaved weaving wire for easy storage and management. Among them, a core wire tube is horizontally arranged at the center of the bottom box 31, and the end of the core wire tube passes through the left and right side walls of the bottom box 31, which is used to convey the core wire and realize the positioning of the core wire; the weaving power motor 32 is used to provide power for the weaving mechanism 3 to realize automatic weaving operation; more than two dials 33 cooperate with the inner wall of the annular groove 311 to form an "8"-shaped runway, and when the dial 33 rotates, it can drive the running spindle 34 to slide in the "8"-shaped runway; a cavity is also provided in the bottom box 31, and a transmission gear is arranged in the cavity. The weaving power motor 32 drives the dial 33 to operate through the transmission gear, thereby driving the running spindle 34 to slide in the "8"-shaped runway, so as to realize the uniform weaving and winding of the yarn on the core wire.The lubrication module 35 is configured to lubricate the "8"-shaped runway to reduce the friction between the running spindle 34 and the dial 33 and the side wall of the annular groove 311, thereby increasing the service life of the device. There are more than two grooves 312, and the grooves 312 correspond to the dials 33 one by one. The heat collecting block 351 can contact the running spindle 34. When the amount of lubricating oil in the annular groove 311 decreases, the friction between the heat collecting block 351 and the running spindle 34 will increase, thereby generating heat, thereby causing the thermal bending sheet 352 to be thermally bent. The sponge oil absorption block 353 absorbs lubricating oil, and when the hot bending sheet 352 is bent by heat, the sponge oil absorption block 353 can be pushed out of the groove 312 and contact the running spindle 34 to achieve the purpose of applying lubricating oil, and then the inside of the runway is completely coated with lubricating oil during the movement of the running spindle 34. Compared with the traditional method of applying oil by atomizing nozzle, on the one hand, it can reduce the volatilization of lubricating oil, and on the other hand, it can absorb the excess oil droplets gathered on the surface of the running spindle 34 or the inside of the runway to avoid being thrown out of the annular groove 311 and causing pollution. The unwinding mechanism 2, the weaving mechanism 3, the traction mechanism 4 and the winding mechanism 5 are all electrically connected to the control panel 6, and the control panel 6 can control the coordinated work of each component.

[0028] Specifically, more than two notches 331 are evenly arranged on the circumferential surface of the dial 33, and the running spindle 34 is snap-fitted and installed in the notches 331. In this embodiment, the notches 331 are semicircular in structure, and when the dial 33 rotates, the notches 331 on two adjacent dials 33 are aligned, and the running spindle 34 can move between the adjacent dials 33.

[0029] Specifically, the lubrication module 35 also includes an oil storage tank 354, a pump body 355 and an oil spray nozzle 356. The oil storage tank 354 is arranged inside the protective shell 1, and the output end of the oil storage tank 354 is connected to the pump body 355. The oil spray nozzle 356 is arranged in the groove 312, and the oil spray nozzle 356 is connected to the pump body 355 through a delivery pipeline. In this embodiment, the oil storage tank 354 is filled with lubricating oil, and a refueling port is provided on the oil storage tank 354 to facilitate the staff to add lubricating oil. The provided pump body 355 can pump the lubricating oil to the oil spray nozzle 356 for spraying, thereby realizing the replenishment of lubricating oil into the sponge oil absorption block 353, so as to ensure that the device can work stably for a long time without frequent shutdown for oiling.

In this embodiment, traction track 401 is arranged horizontally on horizontal plate 11, so that sliding seat 403 can slide left and right in protective shell 1, and electric push rod that can drive it to slide is arranged on sliding seat 403, so as to facilitate adjustment of distance between transmission belt 410 and bottom box 31 to meet different processing needs. The protective cover 402 is used to prevent foreign matter from falling onto traction track 401, so as to protect traction track 401. The vertical plate 404 supports the vertical slide rail 405, and there are two vertical slide rails 405. The mounting seat 408 can move up and down along the vertical slide rail 405. The screw rod 407 is arranged vertically, and the screw rod 407 is provided with two sections of threads with opposite spiral directions, and the two mounting seats 408 are respectively connected to one section of the threads. The provided lifting motor 406 can drive the screw rod 407 to rotate, thereby achieving the effect of driving the two mounting seats 408 to move closer to or away from each other. A transmission belt 410 is horizontally arranged on each mounting seat 408, and the two transmission belts 410 are arranged in parallel. When the two mounting seats 408 are close to each other, the two transmission belts 410 can be driven to move closer to each other synchronously, thereby clamping and fixing the braided wire, and vice versa, the braided wire can be loosened.

[0031] Specifically, guide posts 411 are symmetrically arranged vertically on both sides of the transmission belt 410, and the bottom ends of the guide posts 411 are connected to the sliding seat 403. A slider 412 is slidably connected to the guide posts 411, and a die eye 413 is provided on the slider 412. In this embodiment, the slider 412 can slide up and down along the guide posts 411, so that the position of the die eye 413 can be adjusted adaptively. And one end of the braided wire passes through the die eye 413 and is clamped by the transmission belt 410, which can play a role in assisting the positioning and fixing of the braided wire to prevent it from shaking.

[0032] Specifically, a camera mounting frame 414 is further provided above the traction track 401, and a camera 415 is provided on the camera mounting frame 414. In this embodiment, the camera mounting frame 414 is fixed to the inner top of the protective housing 1, and the camera mounting frame 414 is located between the bottom box 31 and the transmission belt 410. The provided camera 415 can capture image information of the weaving process in real time, and send the captured image data to the control panel 6 for analysis and processing, so as to achieve the effect of real-time monitoring of the weaving quality of the weaving line.

[0033] Specifically, a tension detection module 7 is provided above the unwinding mechanism 2 and the rewinding mechanism 5. The tension detection module 7 includes a crossbeam 71, a weighing seat 72, a fixed block 73 and a guide wheel 74.

In this embodiment, the tension detection module 7 is capable of monitoring the unwinding tension of the unwinding mechanism 2 and the rewinding tension of the rewinding mechanism 5 in real time, thereby preventing the core wire and the braided wire from being broken. Among them, the core wire and the braided wire respectively pass through the grooves on the circumferential surface of one of the guide wheels 74, thereby driving the guide wheel 74 to rotate synchronously. The weighing seat 72 is capable of detecting the pressure on the guide wheel 74, and then obtaining the tension value of the core wire and the braided wire.

[0034] Specifically, the bottom box 31 is an octagonal shell. In this embodiment, the octagonal shell is selected to increase the rigidity of the machine and the long-term working stability.

[0035] Working principle: When in use, the lifting motor 406 and the braiding power motor 32 are started by controlling the control panel 6, the lifting motor 406 will drive the screw rod 407 to rotate, the screw rod 407 drives the two mounting seats 408 to approach each other, and then the transmission belt 410 clamps the core wire, and then the traction motor 409 is started, the traction motor 409 will drive the transmission belt 410 to rotate, and then the core wire is pulled to the right, and at the same time, the braiding power motor 32 drives the dial 33 to rotate through the transmission gear, and the rotation of the dial 33 drives the walking spindle 34 to slide in the "8"-shaped runway, so that the yarn is wound on the surface of the core wire to form a braided wire, and then the winding mechanism 5 winds up the braided wire for easy storage and management. When the core wire and the braided wire roll on the guide wheel 74, the weighing seat 72 will monitor the tension of the yarn and the braided wire in real time to prevent the core wire and the braided wire from being broken due to excessive tension. The pump body 355 is configured to pump the lubricating oil in the oil storage tank 354 to the oil nozzle 356 for spraying, so that the sponge oil absorption block 353 is filled with the lubricating oil. When the amount of lubricating oil in the annular groove 311 decreases, the friction between the heat collecting block 351 and the running spindle 34 will increase and generate heat, thereby causing the hot bending sheet 352 to bend due to the heat. When the hot bending sheet 352 bends, the sponge oil absorption block 353 will be pushed out of the groove 312 and contact the running spindle 34 to achieve the purpose of applying lubricating oil, thereby reducing the friction between the running spindle 34 and the dial 33 and the side wall of the annular groove 311, and improving the service life of the device.
