[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0030] Refer to Figure 1 , Figure 3 and Figure 4 An embodiment provided by the present invention: An auxiliary winding device for a winding machine, including a support steel roller 1, the support steel roller 1 plays a supporting role, and feeding operation is carried out from the top end of the support steel roller 1 to the left end. The left end of the support steel roller 1 is fixedly connected with a rubber roller 3 through two side steel plates. The rubber roller 3 plays a role of connecting and flattening. The left end of the rubber roller 3 is fixedly connected with a rotating steel roller 6 through two side steel plates. The rotating steel roller 6 can rotate 180 degrees as a whole, that is, rotate from A to B. An air shaft 7 is arranged at the left end of the rubber roller 3. A paper core 5 is arranged on the outer arc surface of the air shaft 7. The air shaft 7 is a special winding and unwinding shaft. After being inflated with high pressure, its surface can protrude, and after deflation, the surface part quickly retracts. The paper core 5 is used for winding the sheet material to form a rolled material. The bottom end of the rotating steel roller 6 is fixedly connected with a guide cylinder 10. The guide cylinder 10 is located at the bottom of the rotating steel roller 6, and drives the rotating steel roller 6 to squeeze upward at A through the guide cylinder 10. The guide cylinder 10 is fixedly connected to the surface of the notched gear 11 through a bracket. The bracket is L-shaped. A horizontal notch is arranged at the left end of the notched gear 11, so as to cooperate with the paper core 5 and then be able to rotate around the paper core 5. The right end of the notched gear 11 meshes with a pinion gear 12. By rotating the pinion gear 12, the notched gear 11 is driven to rotate from A to B. After winding is completed, it rotates from B to A. The pinion gear 12 is driven by a fixed servo motor synchronous pulley and a synchronous belt. A cutter 8 is arranged at the left end of the rotating steel roller 6. The cutter 8 is driven by a driving cylinder to move on a linear guide rail, so as to cut the sheet material 2. An auxiliary steel wheel 9 is arranged at the left end of the cutter 8. The auxiliary steel wheel 9 plays an auxiliary connection role. The top end of the support steel roller 1 contacts the sheet material 2, and the sheet material 2 starts to feed from the support steel roller 1.
[0031] Refer to Figures 1-3, the supporting steel roller 1 is fixedly connected to the right end of the rotating steel roller 6 through two side steel plates, and their lateral movement trajectories are the same. The top of the rotating steel roller 6 is located at the bottom of the paper core 5, and the top of the rotating steel roller 6 contacts the bottom of the paper core 5. During operation, first, the supporting steel roller 1, the rubber roller 3, the rotating steel roller 6, the cutting knife 8, and the auxiliary steel roller 9 are integrally fixed on the two side steel plates and connected to the movable end of the horizontal cylinder through the fixed sliders at the bottom of the steel plates. By moving the movable end of the horizontal cylinder, the whole is moved until the rubber roller 3 presses against the winding paper core 5. After the whole stops, the rotating steel roller 6 is moved upward by the guiding cylinder 10 until it contacts the bottom of the paper core 5, and then the rotating steel roller 6 is rotated from A to B. The rotating steel roller 6 is an integrally chrome-plated steel roller. Chromium plating can improve its wear resistance and corrosion resistance, and the surface is smooth. The two ends of the rubber roller 3 are fixedly connected with one-way bearings 4. Through the setting of the one-way bearings 4, the rubber roller 3 can only rotate counterclockwise. The left end of the rubber roller 3 contacts the outer wall of the sheet 2, and the contact between the two achieves the flattening operation. The top of the sheet 2 contacts the bottom of the paper core 5, and the contact between the two causes the paper core 5 to rotate, so that the sheet 2 can be flattened as a whole. The bottom of the sheet 2 contacts the bottom of the auxiliary steel wheel 9, and the contact between the two can provide a certain tension.
[0032] Working principle: When it is necessary to perform the feeding and winding operation on the sheet 2, the movable end of the horizontal cylinder moves to drive the supporting steel roller 1, the rubber roller 3, the rotating steel roller 6, the cutting knife 8, and the auxiliary steel roller 9 to move laterally. The rubber roller 3 stops when it approaches the paper core 5. The bottom of the sheet 2 contacts the tops of the supporting steel roller 1 and the rubber roller 3 as Figure 1 shown. At this time, the guiding cylinder 10 is started to drive the rotating steel roller 6 to move upward, so that the top of the rotating steel roller 6 contacts the paper core 5. At this time, the rotating steel roller 6 is at the position of A. The driving cylinder cooperating with the cutting knife 8 is started to drive the cutting knife 8 to move horizontally and tighten the sheet 2 with two guide rollers for cutting. Then, the small gear 12 is started to drive the notched gear 11 to rotate from A to B, so as to press the sheet 2. After the sheet 2 is pressed at the B position, the rotating steel roller 6 ensures that the inlet end of the sheet 2 is neat, and the air shaft 7 and the paper core 5 rotate synchronously to drive the rubber roller 3 to rotate synchronously. This rubber roller 3 can only rotate counterclockwise through the one-way bearing 4 to wind the sheet 2 into the paper core 5, and the sheet 2 will not be unable to be wound into the paper core 5 due to the reverse rotation of the rubber roller 3.
[0033] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
