Example (b):

the cotton cutting machine with the die comprises a rack, a cutting mechanism and a die assembly 3 for fixing the pearl cotton sheets, wherein the cutting mechanism and the die assembly 3 are arranged on the rack, and the die assembly 3 is controlled by a moving assembly to cut edges of the pearl cotton sheets 7 for one circle through the cutting mechanism. The rack comprises an upper table board 1 and a box body 2, wherein the upper table board 1 is positioned above the box body 2, the die assembly 3 is positioned above the upper table board 1, part of the cutting mechanism is positioned above the upper table board 1, and the other part of the cutting mechanism is positioned inside the box body 2. The bottom of the box body 2 is also provided with universal wheels 10, so that the box body can be conveniently carried to different positions for use.

The mold assembly 3 includes a lower mold 301 and an upper mold 302, and referring to fig. 3, the outer edge of the lower mold 301 protrudes upward, and the lower mold 301 has a size slightly larger than that of the upper mold 302 so that the upper mold 302 can be completely placed inside the lower mold 301. The upper mold 302 can be clamped in the lower mold 301, that is, a notch with the same shape as the upper mold 302 is formed on the inner bottom surface of the lower mold 301, and the pearl cotton sheet 7 to be edged is pressed in the lower mold 301 by the upper mold 302, because the upper mold 302 is clamped with the lower mold 301, the pearl cotton sheet 7 cannot be separated from the position when the mold assembly passes through the cutting mechanism.

Because the outer edge of the pearl cotton sheet 7 is exposed outside the whole mold assembly 3 for cutting, in this embodiment, the height of the raised outer edge of the lower mold 301 needs to be slightly higher than the height of the upper end surface of the upper mold 302 when the upper mold 302 and the pearl cotton sheet 7 are both placed in the lower mold 301. Meanwhile, the central position of the pearl cotton sheet 7 is fixed by the upper die 302, and since the pearl cotton sheet 7 is a semi-finished product to be processed, the shape and size of which is slightly larger than those of the lower die 301, after the pearl cotton sheet 7 is placed in the lower die 301 and adjusted, the edge (the part to be cut) of the pearl cotton sheet 7 is higher than the convex outer edge of the lower die 301.

The cutting mechanism in this embodiment is a band knife mechanism 15, and the band knife mechanism 15 may be an existing device including a driving wheel, a driven wheel and a cutting band, and the working principle thereof is not described in detail herein. In the device, the centers of the driving wheel and the driven wheel are positioned on the same horizontal line, the wheel body is partially higher than the upper table surface 1, and the upper table surface 1 is provided with a notch for the wheel body to extend out. In order to ensure the cutting quality, the cutting belt above the upper table 1 is at the same level with the upper end surface of the convex outer edge of the lower die 301, so that the part exceeding the lower die 301 is cut off, as shown in fig. 1, and the cotton edge 11 is cut off. Because the cutting belt of the band knife mechanism 15 is higher than the upper table top 1, in order to ensure the operation safety, a band knife protective cover 5 and baffle plates 6 positioned at the front side and the rear side are arranged above the band knife mechanism 15, and the band knife mechanism 15 is completely wrapped. Meanwhile, in order to ensure that the cutting belt is still tensioned after long-time use, one end of the driven wheel is provided with a band knife tensioning wheel 12, and the band knife tensioning wheel 12 is positioned outside the box body 2.

The mold component 3 completes the movement through the moving component arranged thereon, the moving component adopted in this embodiment is a ball screw pair, a nut 16 of the ball screw pair is fixed at the bottom end of the lower mold 301, a lead screw 13 of the ball screw pair is located below the upper table top 1, and the axial direction of the lead screw 13 is perpendicular to the central connecting line of the wheel body of the band knife mechanism 15. The upper table top 1 is provided with a moving groove 8 along the axial direction of the screw 13, the nut 16 of the ball screw pair is slidably connected in the moving groove 8, one end of the screw 13 is connected with the output end of the screw motor 14, and the other end of the screw 13 is arranged on the table frame through the mounting seat.

After the pearl wool sheet 7 is pressed on the mold assembly 3, the edge of the pearl wool sheet 7 may exceed the upright part of the upper edge of the lower mold 301. At this point, if the die assembly 3 passes directly over the band knife mechanism 15, a cutting offset may result. Therefore, this embodiment has installed supplementary clamp plate 4 additional before band knife mechanism 15 (along the direction of passing through of mould subassembly 3), and supplementary clamp plate 4 is for locating the type of falling U frame on last mesa 1, and mould subassembly 3 is when the logical groove that forms through supplementary clamp plate 4 and last mesa 1, and the edge that pearl cotton piece 7 is higher than mould subassembly 3 can be pressed downwards by supplementary clamp plate 4, makes the edge of pearl cotton piece 7 folded, and is more stable when the cutting area through band knife mechanism 15.

In addition, the side of the upper table board 1 is also provided with a control button 9, the control button 9 comprises an independent start button and an emergency stop button, and the start button and the emergency stop button can be arranged on two different sides to prevent mistaken touch.

The pearl wool sheet is used for illustration only, and the device is not limited to cutting of the material and can be used for cutting of other materials with elasticity.

It should be understood that the above-mentioned embodiments of the present invention are only examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention, and it will be obvious to those skilled in the art that other variations or modifications may be made on the basis of the above description, and all the embodiments of the present invention are not exhaustive, and all the obvious variations or modifications which are introduced in the technical scheme of the present invention are within the scope of the present invention.
