DETAILED DESCRIPTION

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] Example 1: like Figure 1 、 Figure 2 As shown, the present invention provides a device for synchronously leading out, clamping, positioning and cutting of a roll material. The roll material is installed on a reeling device 1, and the free end of the roll material is led out to the upper table 31 of the cutting table 3 by a first traction device 2; a cutting knife 4 is provided between the cutting table 3 and the first traction device 2, and the rolled material is cut by the cutting knife 4 after being led out.

[0038] Recombination Figures 3 to 7 As shown, the upper surface 31 of the cutting table 3 is provided with two chutes 32 that extend through the upper surface 31. The two chutes 32 are located on either side of the upper surface 31 and are parallel to the direction in which the free end of the web extends. In this embodiment, a pair of avoidance cylinders 52 and a clamping cylinder 53 are respectively installed at the chutes 32 on either side of the cutting table 3 to improve adaptability to webs of varying widths.

[0039] The second traction device 5 includes a servo slide 51 arranged below the upper table 31, and the servo slide 51 is fixed to the cutting table 3 along the direction of the slide 32. There are linear slides 511 on both sides of the servo slide 51, and the linear slides 511 are located below the slide 32. The bracket 54 is fixed to the execution end of the servo slide 51, and the two ends of the bracket 54 are slidably connected to the linear slide 511. A pair of avoidance cylinders 52 and clamping cylinders 53 are respectively installed at both ends of the bracket 54. Under the action of the servo slide 51 and the linear slide 511, the avoidance cylinder 52 and the clamping cylinder 53 can accurately move left and right along the linear slide 511 to complete the precise fixed-length positioning of the material. A tank drag chain is connected to one side of the servo slide 51 to fix the cables.

[0040] Recombination Figures 8 to 10As shown, the end of the bracket 54 is fixed to the avoidance cylinder 52, and the piston rod end of the avoidance cylinder 52 is arranged vertically upward. A support plate 55 is fixed to the piston rod end of the avoidance cylinder 52. The clamping cylinder 53 is fixed under the support plate 55, and the piston rod end of the clamping cylinder 53 is arranged vertically upward. A clamping block 551 is fixed at the end of the support plate 55 relative to the piston rod of the clamping cylinder 53. The clamping block 551 cooperates with the piston rod end of the clamping cylinder 53 to clamp the material. When the avoidance cylinder 52 is extended, the support plate 55 and the piston rod end of the clamping cylinder 53 can be pushed out to the upper side of the chute 32, so as to facilitate the clamping cylinder 53 to clamp the material; when the avoidance cylinder 52 is retracted, the support plate 55 and the clamping cylinder 53 can be pulled into the lower side of the chute 32. At this time, the support plate 55, the avoidance cylinder 52 and the clamping cylinder 53 can move left and right under the upper table 31 without touching the material.

[0041] In this embodiment, the upper surface 31 of the cutting table 3 is covered with an antistatic rubber to protect the web from scratches. Evenly spaced air holes 33 are formed on the upper surface 31 and the antistatic rubber. Air pipes 34 are connected below the air holes 33 and to an air source. During operation, air is blown upward through the air pipes 34 and the air holes 33 toward the upper surface 31, further reducing friction between the web and the upper surface 31 and ensuring cleaning of the upper surface 31, preventing dust accumulation and contamination of the web.

[0042] When working; The free end of the rolled material is led out by the first traction device 2 to the upper surface 31 of the cutting table 3; The servo slide 51 moves to its initial right position, and the avoidance cylinder 52 extends to push the clamping cylinder 53 to the upper side of the chute 32. At this time, the first traction device 2 pulls the free end of the rolled material to the bottom of the clamping cylinder 53, and the clamping cylinder 53 retracts to clamp the free end of the rolled material. Then, the servo slide 51 moves to the predetermined position on the left end, and pulls the roll material of a fixed length to the crane clamping position, and then the cutter 4 cuts the roll material to complete the cutting of the fixed length of the roll material; Finally, the clamping cylinder 53 extends to release the rolled material; the servo slide 51 moves to the left a distance, the clamping cylinder 53 avoids the rolled material, and then the avoiding cylinder 52 retracts, pulling the clamping cylinder 53 to the lower side of the slide 32; the servo slide 51 moves to the right with the avoiding cylinder 52 and the clamping cylinder 53 to the initial position at the right end, ready for the next traction.

[0043] Example 2: Based on the above embodiment 1, combined with Figure 11 、 Figure 12As shown, the unwinding device 1 includes an air-expanding unwinding shaft 11 rotatably mounted on a frame. This shaft 11 is connected to a magnetic powder brake 12 via a gear assembly. During operation, the rolled material is placed on the air-expanding shaft 11. As the air-expanding shaft 11 unwinds the rolled material, the magnetic powder brake 12 controls the material tension. The magnetic powder brake 12 automatically adjusts the tension based on the different winding lengths and thicknesses of the rolled material, ensuring that the material does not shake or wrinkle during unwinding. In this embodiment, two unwinding devices 1 are provided, each with its air-expanding shaft 11 in parallel, allowing for the simultaneous unwinding of two identical or different rolled materials.

[0044] Combine Figure 13 、 Figure 14 As shown, the first traction device 2 comprises a traction roller 21 rotatably mounted on a frame and a pressing rubber roller 22 slidably mounted on the frame. The pressing rubber roller 22 is positioned above the traction roller 21. The traction roller 21 is connected to a traction servo motor 23 via a pulley assembly, while the pressing rubber roller 22 is rotatably mounted on the piston rod end of a pressing cylinder 24. During operation, the free end of the web passes between the traction roller 21 and the pressing rubber roller 22. The pressing cylinder 24 drives the pressing rubber roller 22 to press the web against the traction roller 21 to prevent it from slipping. The traction servo motor 23 drives the traction roller 21 to precisely pull the free end of the web to the left.

[0045] Combine Figure 15 、 Figure 16 As shown, the cutting knife 4 is mounted on the frame for sliding movement up and down, and both sides of the cutting knife 4 are connected to the lifting servo motor 41 through a transmission mechanism; when working, the lifting servo motor 41 drives the cutting knife 4 to move up and down to complete the cutting of the free end of the roll material.

[0046] Example 3: Based on the above embodiment 2, combined with Figure 17 、 Figure 18 As shown, a film rewinding device 6 is also provided on the side of the unwinding device 1 away from the cutting table 3. The film rewinding device 6 includes a rewinding shaft 62 rotatably mounted on the frame and parallel to the unwinding air shaft 11. The rewinding shaft 62 is connected to a rewinding servo motor 61 via a gear assembly. During operation, the surface protective film of the rolled material is rewound onto the rewinding shaft 62, and the rewinding servo motor 61 drives the rewinding shaft 62 to recycle the protective film, thereby achieving automatic film removal and rewinding of the film-coated rolled material.

Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
