Description

Technical Field

[0002] The melt spinning syringe is a special syringe used in the melt spinning process. It is mainly used to load and inject melt spinning materials. These materials are converted into fibers through a specific process after injection. The needle at the bottom of the syringe is responsible for accurately delivering the melt material to the spinning machine or other equipment. During the melt spinning process, laser heating can ensure that the melt at the spinning needle is fully stretched and deposited under the action of a strong electric field to form high-quality nanofibers.

[0003] The automatic calibration devices for melt spinning syringes currently available on the market are mainly improved in terms of functionality and other aspects of automatic calibration. For example, Chinese patent CN209779055U provides an automatic calibration device for a melt spinning syringe, which has the advantage of convenient automatic calibration of a laser transmitter. However, in actual use, when the swing amplitude or jitter of the melt spinning syringe is suddenly too large, the automatic calibration device may take too long to adjust. Therefore, an automatic calibration device for a melt spinning syringe is proposed to solve the above problem. Utility Model Content

[0027] See also Figure 1-4 , an automatic calibration device for a melt spinning syringe, comprising an injection device and a calibration device, wherein the calibration device is arranged on the right side of the injection device.

[0028] Example 1

[0029] The injection device comprises a fixed plate 1, a syringe 2 is clamped in the middle of the bottom of the fixed plate 1, a fixed sleeve frame 3 is sleeved on the outer wall of the syringe 2, a needle 4 is arranged in the middle of the bottom of the syringe 2, and a guide 5 is fixedly installed on the outer wall on the left side of the needle 4.

[0030] In this embodiment, fixing rods 9 are fixedly installed between the left and right ends of the top of the fixing sleeve 3 and the bottom of the fixing plate 1 , and the front, rear, left and right outer walls of the fixing sleeve 3 are rotatably connected with adjusting screws 10 .

[0031] It should be noted that the fixing rod 9 connects the fixing sleeve 3 and the fixing plate 1 to enhance the stability of the fixing sleeve 3 and ensure that the fixing sleeve 3 can be firmly fixed on the fixing plate 1 and is not easy to shake. Rotating the adjusting screw 10 can change the position of the buffer frame 11 in the fixing sleeve 3, thereby adjusting the compression degree of the buffer spring 12. By adjusting the compression degree of the buffer spring 12, the stabilization and shock-absorbing effect of the syringe 2 is achieved, thereby improving the injection accuracy.

[0032] In this embodiment, the adjusting screws 10 all penetrate the outer wall of the fixing sleeve 3 , and the buffer frames 11 are fixedly mounted on the parts of the four adjusting screws 10 inside the fixing sleeve 3 .

[0033] It should be noted that the buffer frame 11 is the fixing point of the adjusting screw 10 and is also the fixing frame of the buffer spring 12, ensuring that the buffer spring 12 can be evenly distributed around the syringe 2 to provide an all-round shock-absorbing effect.

[0034] In this embodiment, a buffer spring 12 is disposed inside the buffer frame 11 , and a connecting rod 13 is fixedly installed at one end of the buffer spring 12 close to the syringe 2 , and the connecting rod 13 is fixedly connected to the outer wall of the syringe 2 .

[0035] It should be noted that the connecting rod 13 ensures that the shock absorbing effect of the buffer spring 12 can directly act on the syringe 2, thereby strengthening the connection between the buffer spring 12 and the syringe 2 and improving the shock absorbing effect.

[0036] Example 2

[0037] The calibration device includes a fixed column 14 arranged at the lower left of the fixed plate 1, a slide groove is opened in the middle of the fixed column 14, a slide column 6 is slidably connected inside the slide groove, a turntable 7 is arranged on the top of the slide column 6, and a laser transmitter 8 is fixedly installed on the top of the turntable 7.

[0039] It should be noted that the gear groove is used to accommodate the rotating gear 16 and transmit the rotational motion of the adjusting rod 15. Through the engagement of the gear groove and the rotating gear 16, the rotational motion of the adjusting rod 15 can be converted into the sliding motion of the sliding column 6 to achieve precise calibration adjustment.

[0040] In this embodiment, a rotating gear 16 is sleeved on the surface of the adjustment rod 15, and the rotating gear 16 is meshed with the gear groove. A mounting block is fixedly installed on the top of the laser transmitter 8, and a calibration laser 17 is rotatably connected to the surface of the mounting block.

[0041] It should be noted that the calibration laser 17 is used to send signals and receive signals from the guide 5 to guide the laser emitter 8 for calibration. By pairing the calibration laser 17 and the guide 5, automatic calibration of the laser emitter 8 can be achieved to ensure that the laser beam can be accurately aligned with the syringe needle, thereby improving the accuracy and efficiency of the calibration.

[0042] In summary, the automatic calibration device for the melt spinning syringe allows the user to fine-tune the tightness of the fixed sleeve 3 to adapt to syringes of different sizes or shapes by adjusting the screw 10 and the buffer frame 11. At the same time, the setting of the buffer spring 12 and the connecting rod 13 can effectively reduce the impact of these forces on the syringe 2 when the syringe 2 is subjected to external shock or vibration, further improving the stability of the syringe. Moreover, by pairing the guide 5 with the calibration laser 17, the laser emitter 8 can be automatically calibrated so that it is accurately aligned with the needle 4, thereby performing accurate heating operations, which is convenient for users.
