It is widely used in punching and cutting non-metallic materials such as foam, cardboard, textiles, plastic materials, leather, rubber, packaging materials, flooring materials, carpets, fiberglass, cork, etc.

[0003] Our company uses a four-post hydraulic cutting machine to punch nonwoven fabrics for nonwoven hygiene products. The nonwovens are fed from the back of the machine, passed under the pressure plate, and punched and cut by the die. A pull plate is pulled out to the front to remove the punched and cut material. The excess waste is then pulled out to the front, the die is replaced, and the pull plate is pushed in for the next punching and cutting. The pulled waste accumulates on the ground below the front of the cutting machine, which is a hindrance and affects the workers' mobility. Furthermore, most cutting machines currently on the market lack a waste collection function, which is inconvenient to use. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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.

[0023] like Figure 1-6 As shown, the utility model provides a technical solution: a precise cutting device for surgical gown materials, comprising a cutting frame 1 and a pressing plate 2 located above the cutting frame 1. Extension brackets 13 are symmetrically installed on the front of the cutting frame 1 near the cutting table. A winding drum 6 is horizontally arranged below the position between the two extension brackets 13. The extension brackets 13 are for facilitating the forward and backward sliding of the upper drag plate 14.

[0024] A sliding shaft seat 3 and a rotating shaft seat 4 are fixedly installed at the front of the cutting machine frame 1 near the positions on both sides. A connecting shaft 5 is horizontally installed in the sliding shaft seat 3 and the rotating shaft seat 4. The opposite ends of the two connecting shafts 5 are fixedly connected to chucks 7 that are movably plugged into the two ends of the winding drum 6. The chuck 7 includes a limit plate 701 and a hollow frustum-shaped plug-in cylinder 702 on one side of the winding drum 6 corresponding to the limit plate 701. The circumferential side of the plug-in cylinder 702 is provided with an extrusion ridge 703, which is convenient for inserting the winding drum 6 from both ends to connect with it;

[0025] The diverging ends of the two connecting shafts 5 are fixedly connected to a vertical inertia flywheel 8. Hand grooves 802 are equidistantly arranged on the side of the inertia flywheel 8 near the circumference, which facilitates the rotation of the inertia flywheel 702. The sliding shaft seat 3, the fixed seat 9, the positioning screw 11 and the handwheel 12 are located on the left side of the winding drum 6, and the rotating shaft seat 4 is located on the right side of the winding drum 6. The frequency of disassembly and assembly of the winding drum 6 is lower than the frequency of winding. This arrangement makes it convenient to rotate the inertia flywheel 8 from the right side to drive the winding drum 6 to wind up the cut waste.

[0026] A fixing seat 9 fixedly mounted on the front side of the cutting machine frame 1 is provided on the side of the inertia flywheel 8 corresponding to the sliding shaft seat 3 facing away from the winding drum 6. The fixing seat 9 is transversely threadedly connected to a positioning screw 11 through an internal threaded sleeve 10. The end of the positioning screw 11 facing away from the inertia flywheel 8 is fixedly connected to a handwheel 12. The end of the positioning screw 11 corresponding to the inertia flywheel 8 is pointed and inserted into a positioning slot 801 on the side of the inertia flywheel 8. The positioning slot 801 is a conical groove located at the center of the side of the inertia flywheel 8, which reduces the friction when in contact with the positioning screw 11.

[0027] Working principle:

[0028] The non-woven fabric is fed from the back of the four-column hydraulic cutting machine, passes through the bottom of the pressure plate 2 and is punched and cut by the knife die. After the drag plate 14 is pulled out to the front to remove the punched and cut material, the excess continuous waste is pulled out to the front, the knife die is rearranged and the drag plate is pushed in for the next punching and cutting. The end of the pulled out continuous waste is fixed to the surface of the winding drum 6 and can be pasted with tape. The inertia flywheel 8 is rotated, and the winding drum is driven to rotate 6 through the inertia flywheel 8, the connecting shaft 5 and the chuck 7 to wind up the excess continuous non-woven fabric waste, so as to prevent the excess non-woven fabric waste from accumulating on the ground and affecting the safety of the staff walking and working;

[0029] To remove the winding drum 6, it is only necessary to turn the left hand wheel 12 counterclockwise. The hand wheel 12 drives the positioning screw 11 to rotate counterclockwise and move to the left to separate from the left inertia flywheel 8. The inertia flywheel 8, the connecting shaft 5 and the chuck 7 are moved to the left along the sliding shaft seat 3, so that the left end chuck 7 is separated from the winding drum 6. At this time, the winding drum 6 can be removed.

[0030] When installing the winding drum 6, put the right end of the winding drum 6 on the plug-in tube 702 of the right chuck 7, align it with the plug-in tube 702 of the left chuck 7, turn the handwheel 2 clockwise, drive the positioning screw 11 to rotate clockwise and move to the right to insert it into the positioning slot 801 of the inertia flywheel 8, continue to turn the handwheel 2 clockwise, drive the left inertia flywheel 8, connecting shaft 5 and chuck 7 to move to the right through the positioning screw 11, and insert the plug-in tube 702 into the winding drum 6. Make sure that the handwheel 12 is tightened and the winding drum 6 is wound clockwise, so as to prevent the positioning screw 11 from loosening during the rotation and winding of the winding drum 6.

[0031] It should be noted that, in this document, terms such as "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements that are inherent to such process, method, article or apparatus.

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
