[0001] This application relates to the technical field of rewinding machines, and particularly to a fully automatic rewinding machine. Background Art

[0002] At present, rewinding machines are generally used for rewinding and slitting materials such as mica tapes, papers, films, non-woven fabrics, etc. mainly by first slitting a wide-width coil material. After the slitting is completed, the narrow-width coil materials after slitting are then wound up, and it is a special processing equipment for coil materials such as papers, mica tapes, films, non-woven fabrics, etc.

[0003] Existing rewinding machines are usually composed of a frame, a slitting mechanism, and winding rollers. When processing coil materials, first, the wide-width coil material is processed into multiple narrow-width coil materials by the slitting mechanism, and then the narrow-width coil materials are wound into multiple coils by the winding rollers for subsequent use.

[0004] Regarding the above related technologies, the inventor believes that there is a defect that after a winding roller winds up a coil of material, it is necessary to first remove the coil material on the winding roller before continuing to wind, resulting in a low use efficiency of the rewinding machine. Summary of the Invention

The connecting plate 183 is a rectangular plate. An installation hole is formed in the connecting plate 183, and a bolt is in threaded fit with the installation hole. By rotating the bolt to make the bolt abut against the connecting rod 181, the connecting plate 183 can be fixedly installed on the connecting rod 181. The pressing brush 184 can directly adopt a rectangular brush, and the pressing brush 184 is installed on the connecting plate 183 by means of bolt fixation. When the coiled material that has been wound up rotates to a position close to the third driving member 142, the pushing frame 141 drives the pressing brush 184 to abut against the outer side surface of the coiled material.

[0051] Refer to Figure 3 and Figure 4 , the free end of the coiled material that has been wound up is located at a position far from the third driving member 142.

[0055] Referring to Figure 5 and Figure 6 , when it is necessary to remove the coiled material wound at the bottom, first start the first driver 73. The piston rod of the first driver 73 extends, driving the clamping bracket 723 to slide in the direction close to the winding roller 3. The clamping bracket 723 pushes the through shaft 722, causing the through shaft 722 to rotate in the direction close to the winding roller 3, driving the rotating rod 71 to rotate, and causing the end of the rotating rod 71 close to the support frame 61 to drive the rotating rod 71, thereby driving the end of the support plate 621 close to the winding roller 3 to rotate away from the winding roller 3, and a gap for the coiled material to pass through is formed between the insertion block 622 and the winding roller 3.

[0056] Referring to Figure 5 and Figure 7 , a pushing device 8 is provided on the frame 1.

When it is necessary to remove the coil material on the lowermost winding roller 3, first start the second driver 841 to drive the mounting bracket 842 and the pushing plate 843 to move towards the winding roller 3, and make the side of the pushing plate 843 away from the winding frame 41 correspond to the side of the coil material. Then start the synchronous belt linear module 83 to drive the mounting plate 82 to move towards the support frame 61. The coil material slips off from the end of the winding roller 3 close to the support frame 61 and falls vertically downward.

[0058] Referring to Figure 2 and Figure 5 , a rectangular mounting opening is provided on the side of the frame 1 close to the support frame 61. A conveying device 9 is installed at the mounting opening. The conveying device 9 is located below the lowermost winding roller 3. The conveying device 9 includes a fixing frame 91 fixedly installed on the frame 1 and a conveying component 92 fixedly installed on the fixing frame 91. The conveying component 92 can directly adopt the method of driving the conveying roller to rotate by a motor, and then driving the conveyor belt wound around the conveying roller to rotate. After the coil material slips off from the winding roller 3, it will fall onto the conveying component 92. Starting the conveying component 92 can convey the coil material out of the frame 1 to complete the rewinding operation of the coil material.

[0059] The implementation principle of an automatic rewinder in an embodiment of the present application is as follows: When it is necessary to perform a rewinding operation on the coil material, first cut the coil material through the slitting mechanism 2. The coil material then passes through the guiding mechanism 12 and reaches the uppermost winding roller 3. Then the winding roller 3 winds the coil material. After the winding is completed, cut the coil material through the cutting mechanism 16. Subsequently, start the driving mechanism 42 to rotate, rotate the winding roller 3 by 90°, then wind the uppermost winding roller 3. After the winding is completed, continue to rotate the winding roller 3 by 90°. When the initially wound winding roller 3 rotates to the lowermost position, start the adjusting device 7 to make the supporting device 6 no longer support the winding roller 3. Then start the pushing device 8 to slip the coil material off from the lowermost winding roller 3 and drop it onto the conveying device 9. The conveying device 9 conveys the coil material out to complete the rewinding operation of the coil material.

[0060] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
