Thus, when the first upper air cylinder and the first lower air cylinder act, the upper guiding plate and the lower guiding plate can be driven to close or open;

[0044] Specifically, by arranging the guiding assembly, when the coil is conveyed, the first upper air cylinder and the first lower air cylinder can act to close the upper guiding plate and the lower guiding plate to clamp the coil and accurately guide the coil, so that the front end of the coil enters the insertion groove of the winding shaft.

[0045] Preferably, as Figure 3 shown, the cutting assembly includes a cutting seat, a cutting motor, a cutting saw blade and a cutting moving mechanism. The cutting seat is slidably connected to the conveying frame horizontally. The cutting motor is installed on the cutting seat. The cutting saw blade is connected to the main shaft of the cutting motor. The cutting moving mechanism is connected to the cutting seat and drives the cutting seat to move horizontally. A conveying area is arranged between the feeding side and the discharging side of the conveying frame. A cutting groove is arranged in the conveying area. The cutting saw blade passes through the cutting groove and extends into the conveying area;

[0046] Specifically, when the coiled material needs to be cut after being wound up, the cutting motor and the cutting moving mechanism are started, driving the cutting seat to move horizontally, so that the cutting saw blade cuts the coiled material in the conveying area.

[0047] Preferably, as Figure 3 shown, a cutting guide rail is arranged below the conveying area of the conveying frame, a sliding block is arranged at the bottom of the cutting seat, and the sliding block is connected with the cutting guide rail in a sliding fit manner, so that the cutting seat is horizontally slidably connected with the conveying frame.

[0048] Preferably, as Figure 3 shown, a pressing mechanism is arranged above the cutting groove of the conveying frame. The pressing mechanism includes a lifting cylinder and a pressing frame. The lifting cylinder is fixed above the cutting groove of the conveying frame and is arranged vertically. The pressing frame is connected with the piston rod of the lifting cylinder.

The body of the second cylinder is hinged to the conveying frame, and the piston rod of the second cylinder is hinged to the flip-up plate. The sleeve cover is installed on the flip-up plate and is rotatably connected with the flip-up plate. When the second cylinder is started, it can drive the flip-up plate to rotate, so that the sleeve cover is in contact with or away from the end of the winding side of the winding shaft.

[0052] Specifically, by setting up the flip mechanism, when the second cylinder drives the flip plate to rotate, after the bushing cover contacts the winding side end of the winding shaft, the winding shaft can be rotationally supported, avoiding the winding effect being affected by the single-sided support state of the winding shaft. And when the winding of the coil material is completed and blanking is carried out, the second cylinder will start again to drive the flip plate to flip towards the side of the conveying rack, so that the bushing cover is away from the winding side end of the winding shaft, and the winding side end of the winding shaft is completely opened, thus blanking and conveying can be carried out.

[0053] Preferably, as Figure 4 shown, the tape pasting mechanism includes a support frame, a lifting module, a tape pasting component and an automatic cutting knife. The support frame is erected on the winding side of the winding shaft. The lifting module is installed on the support frame and is located above the winding side of the winding shaft. The tape pasting component and the automatic cutting knife are installed on the lifting end of the lifting module;

[0054] Specifically, after the winding of the coil material is completed and cut off, the lifting module lowers the tape pasting component and the automatic cutting knife to the coil material. The tape pasting component pastes a tape at the end of the coil material, so that the end of the coil material can be fixed to the coil material itself. Subsequently, the automatic cutting knife cuts the tape, and finally the lifting module rises again to complete the pasting of the end of the coil material.

[0055] Preferably, as Figure 7 and 13 shown, the clamping component includes a clamping plate and a flipping driving device. The clamping plate is located in the cavity. The flipping driving device is installed on the winding shaft and is connected to the clamping plate, and is used to drive the clamping plate to rotate in the cavity to fix the coil material extending into the cavity.

[0056] Preferably, as Figure 9 shown, the clamping plate is a C-shaped clamping plate. The C-shaped clamping plate fits the inner wall of the winding shaft, and the C-shaped clamping plate covers the winding side of the winding shaft along the length direction of the winding shaft, so as to realize complete clamping and fixing of the coil material in the width direction.

[0057] Preferably, a number of saw teeth arranged along the length direction of the C-shaped clamping plate are provided at the opening of the C-shaped clamping plate, so as to strengthen the fixing effect on the coil material through the number of saw teeth and ensure that the coil material will not fall off.

The driving motor is installed on the frame, the driving sprocket is connected to the main shaft of the driving motor, the driven sprocket is installed on the driving side of the winding shaft, and the chain is respectively mounted on the driving sprocket and the driven sprocket.

[0062] Preferably, Figure 8 As shown, a hand wheel is provided on the driving side of the winding shaft, and the hand wheel is fixedly connected to the winding shaft.

[0063] Preferably, Figure 5 As shown, a receiving assembly and a discharging assembly are provided below the reeling side of the reeling shaft;

[0064] Specifically, by setting up a receiving component, when the coil is completed or the coil is large, the receiving component contacts the coil and bears the force on the coil, avoiding the winding shaft from bearing a large force alone and affecting the function of the winding shaft; and the discharging component is set to unload the coil that has completed winding, so that the coil can be discharged from the winding shaft.

[0065] Preferably, Figure 11 As shown, the receiving assembly includes a receiving seat, a first auxiliary roller and a second auxiliary roller, the first auxiliary roller and the second auxiliary roller are symmetrically arranged below the winding side of the winding shaft and are rotatably connected to the receiving seat, a lifting assembly is provided between the second auxiliary roller and the receiving seat, the lifting assembly includes a flip lifting frame, the flip lifting frame is rotatably connected to both sides of the receiving seat, both ends of the second auxiliary roller are connected to one side of the flip lifting frame, a flip cylinder is provided on one side of the receiving seat, the flip cylinder body is hinged to the receiving seat, and the piston rod of the flip cylinder is hinged to the side of the flip lifting frame away from the connection with the second auxiliary roller;

[0066] Specifically, by setting up the lifting component, after the coil is wound up, the flipping cylinder is activated to drive the flipping and lifting frame to rotate, causing the second auxiliary roller to lift upward, so that the end of the coil firmly adheres to the coil itself, which can prevent the end of the coil from falling off and avoid the coil from loosening.

[0067] Preferably, as Figure 5 and Figure 14 shown, the discharging component includes a discharging seat, a discharging track and a discharging driving device. A guiding wheel is arranged at the bottom of the discharging seat, and the guiding wheel is matched with the discharging track. The receiving seat is installed on the discharging seat. U-shaped baffles are arranged at both ends of the discharging seat, and the discharging driving device is used to drive the discharging seat to move;

[0068] Specifically, by setting up the discharging track to limit and guide the movement of the discharging seat, and setting the U-shaped baffles can limit the wound coil within the discharging seat, thus ensuring smooth discharging.

[0069] Preferably, as Figure 14 shown, the discharging driving device includes a discharging motor, a driving gear and a rack. The discharging motor is fixedly connected to the discharging seat, the driving gear is connected to the main shaft of the discharging motor, the rack is installed on the discharging guide rail and arranged parallel to the discharging guide rail, and the driving gear meshes with the rack;

[0070] Specifically, when the coil is discharged after being wound up, the discharging motor is activated to drive the driving gear to rotate. Under the action of the driving gear and the rack, finally, the discharging seat is driven to move along the discharging track, so as to realize the discharging movement of the coil.

[0071] Working process:

[0072] The previous equipment feeds the coil into the conveying frame and enters from the feeding side. Subsequently, the coil exits from the discharging side of the conveying frame into the guiding frame. Then, the first upper cylinder and the first lower cylinder body act, causing the upper guiding plate and the lower guiding plate to close and align with the insertion groove of the winding shaft, precisely guiding the front end of the coil, and enabling the front end of the coil to be conveyed into the insertion groove;

[0073] After the front end of the coil is conveyed into the insertion groove of the winding shaft, the driving cylinder is activated to drive the C-shaped clamping plate to rotate, so that the C-shaped clamping plate closes the notch of the insertion groove and simultaneously clamps the front end of the coil located in the insertion groove, realizing the clamping and fixing of the coil. Then, the air-expanding shaft sleeve is activated and expands. Then, the driving motor is activated to drive the driving sprocket, the chain and the driven sprocket to rotate in sequence. Finally, the winding shaft is driven to rotate, and the coil is wound up until it reaches an appropriate size;

[0074] When the coil is wound to a suitable size, the clamping mechanism on the conveyor frame presses the coil on both sides of the cutting groove, and then the cutting motor and the cutting moving mechanism are started, driving the cutting seat to move horizontally, so that the cutting saw blade cuts the coil in the conveying area. After the cutting is completed, the clamping mechanism releases the pressure on the coil, and then the driving motor continues to drive the winding shaft to rotate, so that the end of the coil is wound from the conveyor frame to the winding shaft;

[0075] When the end of the coil is wound onto the coil on the reel, the tape sticking mechanism starts to work. The lifting module lowers the glue sticking assembly and the automatic cutting knife to the coil. The reel is in continuous rotation, and the glue sticking assembly sticks the tape to the end of the coil so that the end of the coil can be fixed to the coil itself. The automatic cutting knife then cuts the tape. Finally, the lifting module rises again to complete the sticking of the end of the coil.

[0076] After the coil is wound and the end is pasted, the cover mechanism is started, and the second cylinder is started to drive the flip plate to flip toward one side of the conveyor frame, so that the shaft sleeve cover is away from the winding side end of the winding shaft, so that the winding side end of the winding shaft is completely opened, so that the material can be unloaded and conveyed;

[0077] When the coil is being unloaded and conveyed, the air-expanding bearing is deflated, allowing the coil to detach from the reel. Then the unloading assembly is opened, and the unloading motor is started. The unloading motor drives the driving gear to rotate, and with the cooperation of the driving gear and the rack, the entire unloading seat is driven to move along the unloading track. At the same time, under the action of the U-shaped baffle, the coil is limited on the receiving assembly of the unloading seat, and finally moved out of the reel, completing the unloading and unloading. The coil is then taken out manually or by equipment.

[0078] The utility model can accurately guide and convey the coiled material, fix the front end, automatically rewind, cut the end, fix the end, and discharge and unload the material through the guiding conveying and cutting mechanism, the paper tube-free winding mechanism, the tape pasting mechanism, the receiving assembly and the discharging assembly. The whole process is automated, no manual operation is required, and the efficiency is high.

[0079] And a special air shaft structure is adopted. By setting a cavity inside the winding shaft and an insertion groove communicating with the cavity, and arranging a C-shaped clamping plate inside the cavity, a flipping driving device is further arranged between the C-shaped clamping plate and the winding shaft. Thus, the front end of the coil can extend into the insertion groove. Subsequently, the flipping driving device drives the C-shaped clamping plate to rotate, so that the C-shaped clamping plate closes the notch of the insertion groove and clamps the front end of the coil located inside the insertion groove, realizing the clamping and fixing of the coil. There is no need to fix the coil through a paper tube and tape (glue) like the existing air shaft. Moreover, the entire fixing process of the front end of the coil is automatically fixed, without manual operation, and the fixing process takes a short time and has high efficiency, which can effectively improve the overall winding efficiency and is adapted to the existing fully automated production process. At the same time, the overall structure of the air shaft is relatively simple and the cost is relatively low;

[0080] At the same time, a handwheel is also arranged in the air shaft of the present utility model, and the angle of the air shaft can be adjusted through the handwheel, which is convenient for manual adjustment when the insertion groove is not aligned with the front end of the coil and for later maintenance.

[0081] The above are only the preferred embodiments of the present utility model, and the protection scope of the present utility model is not limited to the above embodiments. All technical solutions falling within the idea of the present utility model belong to the protection scope of the present utility model. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and retouches should also be regarded as the protection scope of the present utility model.
