Description

Technical Field

[0001] The present application relates to the technical field of cutting equipment, and in particular to an integrated cutting assembly for a slitting machine. Background Art

[0002] CPP is a polypropylene (PP) film produced by cast extrusion in the plastics industry. After aluminum plating, it can be used as a metallized film for barrier packaging and decoration.

[0003] In some companies, during the production process of CPP film, part of it is aluminum-coated and part of it is not, and the aluminum-coated part and the non-aluminum-coated part are distributed alternately, so the colors are different, like the yin and yang sides, which is what we often call yin and yang film, also called mandarin duck film.

[0004] After the production of the positive and negative films, they will be rolled up and then transferred to the cutting workshop for cutting. The cutting will be done along the black line formed in the contact part of the two color parts of the positive and negative films, so as to separate the aluminized film from the non-aluminized CPP film.

[0005] However, the finished yin-yang membranes produced in different production processes or different production requirements have different widths. In existing production lines, the cutting tools are mostly fixed and the position adjustment is not flexible. In addition, most of the current cutting tools separate the yin-yang membranes like scissors, and the black lines on the contact surface of the yin-yang membranes may not be completely removed, requiring additional trimming.

[0006] To this end, the present application provides a slitting machine integrated cutting assembly to solve the problem of incomplete cutting of the black line at the color matching part of the yin and yang film. Utility Model Content

[0007] The purpose of the present application is to solve the problems existing in the prior art and to propose a slitting machine integrated cutting assembly.

[0008] In order to achieve the above purpose, this application adopts the following technical solutions:

[0010] Preferably, a plurality of cutting grooves are arranged in an array on the transition roller, and the spacing between two groups of cutters is an integer multiple of the spacing between adjacent cutting grooves.

[0014] Preferably, an extension plate is provided on the side of the lower end of the movable frame, and limiting columns are provided on the extension plate at intervals. The limiting columns are plugged into the tool holder, and the tool holder is installed on the extension plate via fasteners.

[0015] Preferably, the limiting column is threadedly connected to the extension plate.

[0016] Preferably, the locking mechanism comprises a bolt, a retaining ring is installed on the end of the bolt, the retaining ring abuts against the bent side wall of the slide rail, and a through hole is provided on the movable frame for the bolt to pass through.

DETAILED DESCRIPTION

[0030] The following will be combined with the attached examples of the present application Figure 1-6 , the technical solutions in the embodiments of the present application are described clearly and completely. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0031] In order to solve the problems existing in the prior art, the present embodiment provides an integrated cutting assembly of a slitting machine, including a transition roller 1 and a yin and yang film on the circumference of the transition roller 1, the yin and yang film are cut by the cutting assembly, the cutting assembly includes a slide rail 2 located above the transition roller 1, a movable frame 3 is slidably mounted on the slide rail 2, a locking mechanism is provided on the movable frame 3, a tool holder 4 is detachably mounted on the lower end side of the movable frame 3, two groups of knives 5 are symmetrically plugged into the tool holder 4, and the spacing between the two groups of knives 5 is adjustable.

[0032] Principle details of this embodiment:

[0033] During the production process, the positive and negative films are spread out from the winding end, pass through multiple tensioning rollers and transition roller 1, are cut by the cutting assembly on the transition roller 1 at the rear side, and are then respectively wound onto other free rolls.

[0034] Before the cutting operation, the tool 5 on the mobile frame 3 is first shifted so that the black line at the color matching contact part of the yin-yang film is located between the two tools 5, and then the mobile frame 3 is fixed to the slide rail 2 through the locking mechanism. The winder is started, and the yin-yang film is pulled and wound. Since the tool 5 is against the yin-yang film, the yin-yang film is cut when it is wound. Since two sets of tools 5 are provided, and the spacing between the two sets of tools 5 can be adjusted according to the width of the black line formed after aluminum plating, the black line is always located between the two sets of tools 5, thereby ensuring the complete removal of the black line, avoiding leaving residues, and reducing the labor burden of subsequent secondary trimming. The mobile frame 3 can adjust its position as the width of the yin-yang film changes, which greatly improves the flexibility of the equipment.

[0035] In a further embodiment of the present solution, a plurality of cutting grooves 10 are arranged in an array on the transition roller 1. The width of the cutting grooves 10 is greater than the width of the cutter 5, leaving cutting space for the cutter 5, so as to avoid the cutter 5 being continuously worn against the surface of the transition roller 1 and shortening the service life. Moreover, even if the positions of the two sets of cutters 5 are adjusted, the spacing between the two sets of cutters 5 is always an integer multiple of the spacing between adjacent cutting grooves 10, so as to ensure that the cutting end of the cutter 5 always falls into the cutting groove 10.

[0036] In a further embodiment of the present invention, a gasket 8 is provided between the two groups of the cutters 5, and the thickness of the gasket 8 is equal to the spacing between the adjacent cutting grooves 10. By increasing or decreasing the number of gaskets 8, the position adjustment between the two groups of cutters 5 is achieved; the shape of the gasket 8 is the same as that of the cutter 5, but the size of the gasket 8 is smaller than that of the cutter 5, so that the cutting section of the cutter 5 leaks out, and the contact surface of the gasket 8 with the side wall of the cutter 5 is increased as much as possible, so that the cutter 5 is clamped more stably and the cutter 5 is prevented from lateral deviation.

[0037] In a further embodiment of the present invention, a scale 11 is provided on the slide rail 2, and the scale lines on the scale 11 correspond one-to-one with the cutting groove 10. A pointer 12 is provided on the movable frame 3 to cooperate with the scale 11. When the pointer 12 points to the scale on the scale 11, the two cutters 5 correspond to the cutting groove 10. In this way, when adjusting the position of the movable frame 3, it is only necessary to transfer the corresponding relationship between the pointer 12 and the scale to determine whether the cutter 5 is aligned with the cutting groove 10 after the transfer, without the need to compare the positive and negative membranes with the naked eye, thereby improving the efficiency of the position adjustment of the movable frame 3.

[0038] In a further embodiment of the present invention, two insertion rods 17 are symmetrically arranged on the tool holder 4, and insertion holes corresponding to the insertion rods 17 are arranged on the tool 5 and the gasket 8, and a first through hole is arranged at the center of the center line of the two insertion holes on the tool 5, and a first threaded hole corresponding to the first through hole is arranged on the tool holder 4. When clamping, the tool 5 is pinched so that the insertion rods 17 pass through the insertion holes, and the tool 5 is positioned by the two insertion rods 17 to prevent the tool 5 from deflecting during the cutting process. Then, fasteners such as screws 7 are passed through the first insertion hole and connected to the first threaded hole, so that the tool 5 is stably mounted on the tool holder 4.

[0039] In a further embodiment of the present scheme, an extension plate 9 is provided at the lower side of the mobile frame 3, and a limiting column 16 is provided at intervals on the extension plate 9, and a second insertion hole is provided on the tool holder 4. During clamping, the limiting column 16 is passed through the second insertion hole, and then the tool holder 4 is fastened and installed on the extension plate 9 by fasteners such as studs 6, so as to realize the limited installation of the tool holder 4. The provision of the extension plate 9 also improves the spatial mobility between the tool 5 and the transition roller 1, and also increases the space between the slide rail 2 and the transition roller 1, which facilitates the guidance of the positive and negative membranes during dry spreading, as well as the disassembly and assembly of various equipment.

[0040] In a further embodiment of the present invention, the limiting column 16 is threadedly connected to the extension plate 9. Before the position of the mobile frame 3 is adjusted, the stud 6 is loosened, and then the limiting column 16 is screwed, so that the limiting column 16 is separated from the tool holder 4, and the tool holder 4 loses its limit. The tool holder 4 is deflected to prevent the cutting section of the tool 5 from hitting the cutting groove 10 when the mobile frame 3 is transferred. When the position adjustment of the mobile frame 3 is completed, the tool holder 4 is locked.

[0041] In a further embodiment of the present solution, the present embodiment provides a specific structure of a locking mechanism: comprising a bolt 13, a through hole for the bolt 13 to pass through is provided on the mobile frame 3, a plum blossom handle is provided at the head end of the bolt 13, and a retaining ring 14 is threadedly installed at the tail end, and the retaining ring 14 abuts against the bent side wall of the slide rail 2. The structure of the slide rail 2 is similar to a T-shape. When in use, the retaining ring 14 abuts against the edge of the slide rail 2, thereby clamping the mobile frame 3 on the slide rail 2, thereby fixing the mobile frame 3.

[0042] In a further embodiment of the present scheme, a cleaning assembly for discharging cut fragments is also included; the cleaning assembly includes a negative pressure pipe 15 corresponding to the movable frame 3 one by one, the negative pressure pipe 15 is connected to a negative pressure device, and the negative pressure pipe 15 is suspended on the side of the transition roller 1 (only a part of the negative pressure pipe 15 is shown in the accompanying drawing).

[0043] The negative pressure device forms negative pressure in the negative pressure tube 15, so that during the cutting process, the cut black line is sucked into the negative pressure tube 15 and then discharged to the designated collection area, avoiding the cut pieces from floating around, thus ensuring the cleanliness of the entire equipment and avoiding entanglement in the transmission part to affect the transmission stability.

[0044] In a further embodiment of the present invention, the negative pressure tube 15 is a corrugated tube, so that the negative pressure tube 15 can be stretched and extended, and can be moved more flexibly and conveniently with the position of the mobile frame 3.

[0045] In this solution, in order to facilitate the display of the drawings and reduce the impact of dense lines on the viewing of the drawings, the spacing between adjacent cutting grooves 10 and the spacing between scales on the scale 11 are adaptively enlarged.

Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed in the present application according to the technical solution and application concept of the present application, which should be covered by the protection scope of the present application.
