The above structure is basically the same as that of the existing winding device, except that:

[0024] The automatic winding device of the cotton roll provided by the present invention also includes a paper feeding structure for feeding paper (specifically, vellum paper or kraft paper, etc.) to the upper side of the cotton cloth for separating each circle of cotton cloth. Furthermore, the paper feeding structure can be used or not (paper 23 is not output, and each structure thereon is not operated). The winding structure in this embodiment can realize the automatic winding and discharging of the cotton roll. The winding structure includes a horizontal belt 5 (moving backward) arranged in the front-to-back direction (horizontally arranged) and a pressure roller mechanism 6 (used to press the cotton cloth on the horizontal belt 5 to ensure that the cotton cloth is transported backward), a vertical winding mechanism 7, a positioning mechanism 8 and an inclined winding mechanism 9 arranged in sequence above the horizontal belt 5 from front to back; the horizontal belt 5, the vertical winding mechanism 7, the positioning mechanism 8 and the inclined winding mechanism 9 cooperate to realize the winding of the cotton cloth roll 16. When the cotton cloth roll 16 is wound, the horizontal belt 5, the vertical winding mechanism 7 and the inclined winding mechanism 9 form a triangular structure and the arrangement method thereof should ensure that the cotton cloth can be wound into the cotton roll 16.

Among them, the middle part (left and right sides) of the pressing roller frame 17 is rotatably arranged on the rear end of the front turning frame 10 through left and right rotating shafts (two in total, symmetrically arranged on the left and right, specifically the front rotating shaft) and two pressing rollers 11 are arranged side by side on the front and back, the front end of the front turning frame 10 is rotatably arranged on the frame, the pressing roller 11 is arranged in the left and right direction and can press the cotton cloth against the horizontal belt 5, and the front turning frame 10 can be driven by the front driving unit to turn upward so that the pressing roller 11 leaves the cotton cloth. The vertical winding mechanism 7 includes vertical brackets 12 on the left and right sides of the frame (specifically, it can be a door-type frame or two vertical beams arranged side by side on the left and right sides, located on the left and right sides of the cotton cloth), a vertical belt 13 vertically arranged on the vertical bracket 12, and a front belt driving unit driving the vertical belt, etc. The vertical belt 13 is located adjacent to and above the horizontal belt 5 (the cotton cloth can pass through). The inclined winding mechanism 9 includes a rear flip frame 14 arranged along the front-to-back direction and rotatably arranged on the frame, an inclined belt 15 on the rear flip frame 14 and arranged along the front-to-back direction (when flipping upward, it is arranged obliquely downward from front to back), a rear flip driving unit driving the rear flip frame 14 to flip, and a rear belt driving unit driving the inclined belt 15, etc. The rear end of the rear flip frame 14 is rotatably arranged on the frame and can be driven by the rear flip driving unit to flip upward, and the front end of the inclined belt 15 is located adjacent to the rear of the vertical belt 13 and adjacent to and above the horizontal belt 5 (the cotton cloth cannot pass through). The positioning mechanism 8 includes two top plates (vertical plates) located on the left and right sides of the cotton roll 16, respectively. The two top plates can move toward or away from each other synchronously. The top plates are located above the horizontal belt 5 and behind the vertical belt 13. The top plates are required not to affect the inclined winding mechanism 9. The speeds of the horizontal belt 5, the vertical belt 13 and the inclined belt 15 are coordinated (the linear speeds are the same), the rear side of the vertical belt 13 moves downward, the lower side of the inclined belt 15 moves forward, and the horizontal belt 5 moves backward.The paper feeding structure includes a paper feeding bracket (composed of two side plates arranged side by side on the left and right, with a paper roll 18, a paper guiding mechanism 19, a paper output mechanism 20 and a paper cutting mechanism 21 arranged between the two side plates) and the paper roll 18, the paper guiding mechanism 19 (used to guide the paper 23 and adjust the tension of the paper 23, and to prevent it from being pulled at will), the paper output mechanism 20 (used to output the paper 23 backward and downward), the paper cutting mechanism 21 (used to cut the paper 23) and the paper discharge mechanism 22 (used to lead the paper 23 out), etc., which are arranged on it from top to bottom in sequence. The paper feeding bracket is arranged on the frame, and the paper discharge mechanism 22 is located above between the rear feed roller structure 4 and the pressure roller frame 17. The paper 23 is obliquely discharged backward and downward from the paper discharge mechanism 22 to between the pressure roller 11 and the cotton cloth.

[0025] The working process of the device is as follows: when the cotton roll 16 is wound, the pressure roller 11 presses the paper 23 (optional) against the cotton cloth, the cotton roll 16 is placed on the horizontal belt 5 and its front side is pressed against (pressed by the inclined belt 15) the rear side of the vertical belt 13, the lower side of the inclined belt 15 is pressed against the rear upper side of the cotton roll 16, the two top plates move towards each other and press against the left and right sides of the cotton roll 16 respectively to ensure that the two sides are neat during winding, and the rear turning frame 14 gradually turns upward as the cotton roll 16 becomes larger. After the cotton roll 16 is wound (when the cotton cloth reaches a certain length or weight), the cutting structure 3 cuts the cotton cloth, the paper output mechanism 20 stops feeding the paper 23 and the paper cutting mechanism 21 cuts the paper 23 (this process may be omitted), the front flip frame 10 flips upward to make the pressure roller 11 leave the cotton cloth, the rear flip frame 14 continues to flip upward to make the inclined belt 15 leave the cotton roll 16, the two top plates move away from each other and separate from the corresponding side of the cotton roll 16, and the horizontal belt 5 conveys the cotton roll 16 backward and passes under the upwardly flipped inclined belt 15. Among them, the cutting structure 3 in this embodiment is similar to the existing structure. Among them, in this embodiment, if the paper 23 is abnormally output (the cotton cloth is not output backward, but the paper 23 is continuously output backward (the paper 23 cannot adhere to the cotton cloth, and it will not be affected for a short time)), the paper 23 can be wound on the rear side of the pressure roller 11 to prevent the horizontal belt 5 from outputting the paper 23 backward. The pressing roller 11 in this embodiment has the function of closely fitting the cotton cloth and the paper 23, and also has the function of cooperating with the horizontal belt 5 to transport the cotton cloth or the cotton cloth and the paper 23 backward. The pressing roller frame 17 and the pressing roller 11 form a floating pressing structure to ensure the pressing and compounding effect.
