[0015] The utility model is provided with a nozzle that connects the needle part of the syringe barrel to the top of the device through a hose, and uses a movable frame to slide on a slide bar, so as to drive the nozzle to move left and right, so as to realize more injection directions in the spinning process, and provide greater flexibility and freedom.

[0017] The utility model is provided with a first motor to drive the first rotating shaft to rotate, and a heat-insulating material coating is provided on the first rotating shaft, because the adhesion of high-temperature fibers may cause the resistance of the rotating shaft to increase, which may affect the normal operation of the equipment and be difficult to remove. The heat-insulating material coating can prevent the high-temperature fibers from adhering to the first rotating shaft, thereby protecting the normal operation of the first rotating shaft. This helps to extend the service life of the first rotating shaft and improve the stability of the equipment. The second motor drives the second rotating shaft to rotate, and the fibers sprayed onto the first rotating shaft can be brought to the second rotating shaft, which is convenient for collecting the fibers. Through the rotation of the second rotating shaft, the fibers can be wound onto the second rotating shaft, making the collection and processing of the fibers more convenient and efficient.

The surfaces of the first rotating shaft 202 and the second rotating shaft 204 are fixedly connected to a heat insulation material coating 206.

[0030] The support mechanism 3 includes a workbench 301, the bottom of the connection seat 201 is fixedly connected to the workbench 301, the bottom of the workbench 301 is fixedly connected to a support column 302, the bottom of the support column 302 is fixedly connected to a support pad 303, and the top of the workbench 301 is fixedly connected to a placement table 304.

[0032] The implementation principle of the injection device of an electrospinning machine in the embodiment of the present application is: by setting the needle 111 part of the syringe barrel 107 to the external connection hose 112 to the nozzle 405 on the top of the device, and using the moving frame 402 to slide on the slide bar 401, the nozzle 405 can be driven to move left and right, which can realize more injection directions during the spinning process, providing greater flexibility and freedom. The spinning machine can produce more diverse fiber structures and shapes, and at the same time, the sprayed spinning liquid is more evenly distributed in the spinning area, reducing the residence time of the spinning liquid on the surface of the nozzle 405, thereby reducing the coagulation and aggregation of the spinning fibers, and reducing the occurrence of blockage and adhesion problems.

The motor is set to drive the threaded column 102 to rotate (the motor is on the left side of the fixed plate 101, and the motor that drives the threaded column 102 to rotate is not shown in the figure). The threaded column 102 rotates and drives the connecting block 104 to rotate and move forward, pushing the piston rod 106 to move forward, and the piston rod 106 pushes the syringe barrel 107, so that the water in the syringe barrel 107 reaches the needle 111, and the hose 112 connected to the surface of the needle 111 is connected to the water inlet 404 of the nozzle 405, and the water in the syringe barrel 107 is sprayed out through the nozzle 405 to achieve the effect of spraying water. The threaded column 102 is driven to rotate by the motor, the connecting block 104 moves forward, the piston rod 106 is pushed forward, and finally the syringe barrel 107 is pushed, so that the water reaches the needle 111. The two ends of the hose 112 are respectively connected to the needle 111 and the nozzle 405, so that the water can flow smoothly. Since the hose 112 is used to connect the needle 111 and the nozzle 405, the position and angle of the water spray can be easily adjusted and changed. Through the structure of the threaded column 102 and the piston, more precise water control can be achieved, and the amount and speed of the water spray can be adjusted. The first motor 203 is set to drive the first rotating shaft 202 to rotate, and the first rotating shaft 202 is provided with a heat insulation material coating 206, because the adhesion of high-temperature fibers may cause the shaft resistance to increase, which affects the normal operation of the equipment and is difficult to remove. The heat insulation material coating 206 can prevent the high-temperature fibers from adhering to the first rotating shaft 202, thereby protecting the normal operation of the first rotating shaft 202. This helps to extend the service life of the first rotating shaft 202 and improve the stability of the equipment. The second motor 205 drives the second rotating shaft 204 to rotate, and can bring the fibers ejected onto the first rotating shaft 202 to the second rotating shaft 204, so as to facilitate the collection of the fibers. Through the rotation of the second rotating shaft 204, the fibers can be wound onto the second rotating shaft 204, making the collection and processing of the fibers more convenient and efficient.
