[0003] Currently, the existing fixation between the coil and the paper tube is achieved by gluing or taping the front end of the coil to the paper tube. This fixation method requires manual operation, and the operation process is cumbersome and inefficient. Therefore, it is necessary to design and develop a coil winding air shaft that can automatically fix the coil. Summary of the Utility Model

This coil winding air shaft can automatically fix the front end of the coil, with high fixation efficiency and firm fixation, effectively improving the overall winding efficiency. The overall structure is relatively simple and can solve the above technical problems.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0059] Specifically, by providing the receiving assembly 4, when the coil is completed or the coil is large, the receiving assembly 4 contacts the coil and bears the force on the coil, thereby preventing the reel 2 from bearing a large force alone and affecting the function of the reel 2;

[0060] The discharging assembly 5 is provided to discharge the coiled material that has completed winding, so that the coiled material is discharged from the winding shaft 2.

[0061] Preferably, as Figure 10 shown, the receiving assembly 4 includes a receiving seat 401, a first auxiliary roller 402 and a second auxiliary roller 403. The first auxiliary roller 402 and the second auxiliary roller 403 are symmetrically arranged below the winding side 202 of the winding shaft 2 and are rotatably connected to the receiving seat 401.

[0062] Preferably, as Figure 10 shown, a lifting assembly is provided between the second auxiliary roller 403 and the receiving seat 401.

The body of the flipping cylinder 404 is hinged to the receiving seat 401, and the piston rod of the flipping cylinder 404 is hinged to the side of the flipping and lifting frame 405 away from the side connected to the second auxiliary roller 403.

[0063] Specifically, by providing the lifting assembly, after the coiled material is wound, the flipping cylinder 404 is activated to drive the flipping and lifting frame 405 to rotate, so that the second auxiliary roller 403 is lifted upward, making the end of the coiled material firmly adhere to the coiled material itself, which can prevent the end of the coiled material from falling off and avoid the coiled material from unwinding loosely.

[0064] Preferably, as Figure 6 and 13 shown, the discharging assembly 5 includes a discharging seat 501, a discharging track 503 and a discharging driving device. Guide wheels are provided at the bottom of the discharging seat 501. The guide wheels cooperate with the discharging track 503. The receiving seat 401 is installed on the discharging seat 501. U-shaped baffles 504 are provided at both ends of the discharging seat 501. The discharging driving device is used to drive the discharging seat 501 to move.

[0065] Specifically, by providing the discharging track 503 to limit and guide the movement of the discharging seat 501, and by providing the U-shaped baffles 504, the coiled material wound can be restricted within the discharging seat 501, thus ensuring smooth discharging.

[0066] Preferably, as Figure 13 shown, the discharging driving device includes a discharging motor 502, a driving gear 505 and a rack 506. The discharging motor 502 is fixedly connected to the discharging seat 501. The driving gear 505 is connected to the main shaft of the discharging motor 502. The rack 506 is installed on the discharging guide rail and is arranged parallel to the discharging guide rail. The driving gear 505 meshes with the rack 506.

[0067] Specifically, when the coil is finished winding and ready for discharge, the discharge motor 502 starts, driving the drive gear 505 to rotate, and under the action of the drive gear 505 and the rack 506, the discharge seat 501 is finally driven to move along the discharge track 503, thereby realizing the discharge movement of the coil.

[0068] Working process and advantages:

[0069] When the coil is being wound, the preceding equipment feeds the front end of the coil horizontally to the winding side 202 of the winding shaft 2 and into the insertion slot 204. The air cylinder 11 is then driven to start, driving the C-shaped clamping plate to rotate, so that the C-shaped clamping plate closes the notch of the insertion slot 204 and clamps the front end of the coil in the insertion slot 204, thereby clamping and fixing the coil. The air bearing 15 is then started and expanded, and the driving motor 3 is then started, driving the driving sprocket 6, the chain 8 and the driven sprocket 7 to rotate in sequence, and finally driving the winding shaft 2 to rotate, starting to wind the coil, and finally completing the winding.

[0070] When the coil is completely wound, the cutting device cuts off the end of the coil so that the end of the coil is also completely wound. Then the lifting assembly is started, the turning cylinder 404 is started, and the turning lifting frame 405 is driven to rotate, so that the second auxiliary roller 403 is lifted upward, so that the end of the coil is firmly attached to the coil itself, which can prevent the end of the coil from falling off and the coil from being loosened.

[0071] Finally, the air-expanding bearing 15 is deflated to allow the coil to detach from the winding shaft 2, and then the discharge component 5 is opened, and the discharge motor 502 is started. The discharge motor 502 drives the driving gear 505 to rotate, and with the cooperation of the driving gear 505 and the rack 506, the entire discharge seat 501 is driven to move along the discharge track 503. At the same time, under the action of the U-shaped baffle 504, the coil is limited on the receiving component 4 of the discharge seat 501, and finally moved out of the winding shaft 2 to complete the discharge and unloading.

[0072] The utility model provides a reel 2, a cavity 203 and an insertion slot 204 connected to the cavity 203 are provided in the reel 2, and a C-shaped clamping plate is provided in the cavity 203, and a turning drive device is provided between the C-shaped clamping plate and the reel 2, so that the front end of the coil can be inserted into the insertion slot 204, and then the turning drive device drives the C-shaped clamping plate to rotate, so that the C-shaped clamping plate closes the notch of the insertion slot 204 and clamps the front end of the coil located in the insertion slot 204, so as to clamp and fix the coil. There is no need to fix the coil by paper tube and adhesive tape (glue) as in the existing air expansion shaft. Moreover, the whole process of fixing the front end of the coil is automatic, without manual operation, and the fixing process is short in time and efficient, which can effectively improve the efficiency of the overall reeling and is suitable for the existing fully automated production process. At the same time, the structure of the overall air expansion shaft is relatively simple and the cost is relatively low.

[0073] In addition, the pneumatic shaft in the present invention is also equipped with a hand wheel 9, by which the angle of the pneumatic shaft can be adjusted, which is convenient for manual adjustment when the insertion slot 204 is not aligned with the front end of the coil and for later maintenance; at the same time, a receiving component 4 and a discharging component 5 are provided, which cooperate with the winding shaft 2 to realize the winding, coil receiving and unloading of the coil.
