Description

Technical Field

[0001] This utility model relates to the field of cutting and processing, and discloses a slitting machine. Background Technology

[0002] A slitting machine is a mechanical device used to cut wide rolls of material into narrow strips. For example, it can slit and rewind aluminum foil, copper foil, and composite foil. During the slitting process, the machine generates waste debris. To reduce the impact of this debris on the machine's mechanical transmission structure and the material being slitted, negative pressure suction pipes are currently installed to collect the waste debris. While these pipes are effective at collecting smaller pieces of dust, they are not reliable for larger waste materials such as edge pieces. Therefore, there is an urgent need for a slitting machine that improves the efficiency of waste debris collection. Utility Model Content

[0028] Reference Figure 1According to a first aspect of the present invention, a slitting machine includes a base 100, an unwinding mechanism 200, a slitting mechanism 300, a material suction mechanism 400, and a winding mechanism. The unwinding mechanism 200 is disposed on the base 100 and has a rotatable unwinding roller. In practical applications, the unwinding roller can rotate when the material strip is pulled out, at which point the unwinding mechanism 200 may not contain a motor, or it may contain a motor that drives the unwinding roller to rotate, thereby actively unwinding. The slitting mechanism 300 is disposed on the base 100 and has multiple cutters 310 spaced apart along a direction parallel to the unwinding roller. The material suction mechanism 400 includes a main pipe 410, a negative pressure source, a connecting frame 420, a transfer roller 430, and a pressure roller 440. The main pipe 410 and the connecting frame 420 are connected to the base 100. 0. The negative pressure source is interconnected with the main pipe 410. The negative pressure source is used to create negative pressure inside the main pipe 410. The negative pressure source can be a vacuum pump. Multiple suction pipes 480 are spaced apart on the bottom side of the main pipe 410. Multiple pressure rollers 440 are provided on the connecting frame 420. Multiple pressure rollers 440 form material passage gaps with the transfer rollers 430 respectively. Multiple suction pipes 480 extend to the material passage gaps respectively. In practical applications, the transfer rollers 430 can be passively rotated on the base 100, or a motor can be directly configured inside the suction mechanism 400, which drives the transfer rollers 430 to rotate, thereby actively sending the waste material to the suction pipes 480. The winding mechanism has a rotatable winding roller 500. Naturally, the winding mechanism has a motor inside, which drives the winding roller 500 to rotate, thereby realizing the winding of the slit strip.

[0029] As described above, the cylindrical roll material to be slit is loaded into the unwinding roller and unwound. The unwound strip is then guided through the slitting mechanism 300 and onto the take-up roller 500. When the strip passes through the slitting mechanism 300, multiple cutters 310 within the slitting mechanism 300 slit the strip into multiple strips. During the slitting process, small debris and dust are generated and are sucked into the main pipe 410 by multiple suction pipes 480 with negative pressure. Larger waste materials, such as edge materials, are wound upwards into the pressure roller 440 and transfer roller after slitting. Within the material passage gap between rollers 430, the waste material is guided and limited by the pressure roller 440 and the intermediate roller 430, and can smoothly enter the main pipe 410 through the negative pressure of the suction pipe 480. Finally, the waste material is discharged and collected outward through the main pipe 410. In this way, the waste material generated during slitting can be adsorbed and recycled. Furthermore, for larger waste materials such as strips, they can also be stably adsorbed and recycled under the guidance of the pressure roller 440 and the intermediate roller 430, thereby improving the cleanliness of the slitting machine during operation and the recycling rate of materials.

[0030] To facilitate adjustment of the position of the pressure roller 440 relative to the intermediate transfer roller 430, such as Figure 2 As shown, in this embodiment, a plurality of first adjusting frames 450 are arranged on the connecting frame 420 in a direction parallel to the unwinding roller. The plurality of first adjusting frames 450 can be moved and positioned on the connecting frame 420 in a direction parallel to the unwinding roller. A plurality of pressure rollers 440 are rotatably connected to the plurality of first adjusting frames 450. There are various ways in which the first adjusting frames 450 can be moved and positioned on the connecting frame 420. For example, the first adjusting frame 450 is slidably connected to the connecting frame 420, and a first bolt is passed through the first adjusting frame 450. When the first bolt is away from the connecting frame 420, the first adjusting frame 450 can move on the connecting frame 420. When the end of the first bolt abuts against the connecting frame 420, the first adjusting frame 450 can be relatively positioned on the connecting frame 420. Before slitting the strip, the position of the first adjusting frame 450 on the connecting frame 420 can be adjusted according to the location of the waste generated by slitting the strip, so that the waste generated can enter the position between the pressure roller 440 and the intermediate roller 430 accordingly.

[0031] Similarly, to facilitate the adjustment of the position of the suction pipe 480 relative to the transfer roller 430, in this embodiment, a plurality of second adjustment frames 460 are provided on the connecting frame 420 in a direction parallel to the unwinding roller. The plurality of second adjustment frames 460 can be moved and positioned on the connecting frame 420 in a direction parallel to the unwinding roller. The plurality of suction pipes 480 are respectively connected to the plurality of second adjustment frames 460. The plurality of suction pipes 480 are respectively connected to the main pipe 410 by hoses 470. There are various ways in which the second adjustment frame 460 can be moved and positioned on the connecting frame 420. For example, the second adjustment frame 460 is slidably connected to the connecting frame 420, and a second bolt is passed through the second adjustment frame 460. When the second bolt is away from the connecting frame 420, the second adjustment frame 460 can move on the connecting frame 420. When the end of the second bolt abuts against the connecting frame 420, the second adjustment frame 460 can be positioned relative to the connecting frame 420. Before the material strip is cut, the position of the second adjusting frame 460 on the connecting frame 420 can be adjusted according to the location of the waste generated by the cutting of the material strip, so that the suction pipe 480 is closer to the location of the waste generated, and the hose 470 between the suction pipe 480 and the main pipe 410 can be flexibly adjusted to ensure the connection between the suction pipe 480 and the main pipe 410.

[0032] The cutter 310 within the slitting mechanism 300 can be fixed. When slitting the material strip, it relies solely on the blades on the cutter 310 to cut the strip. After prolonged use, the strip is prone to exhibiting uneven cuts. To improve the slitting effect of the material strip, such as... Figure 3As shown, in this embodiment, the slitting mechanism 300 includes a connecting shaft 320, blade holders 330, and drive motors 340. Multiple blade holders 330 are spaced apart on the connecting shaft 320 along a direction parallel to the unwinding roller. Each blade holder 330 is connected to a drive motor 340, and each drive motor 340 drives a cutter 310. During operation, the multiple drive motors 340 drive the multiple cutters 310 to rotate, thereby cutting the material strip and effectively improving the flatness of the material strip slitting and the service life of the cutters 310. In practical applications, the multiple blade holders 330 can also move and be positioned along the axial direction of the connecting shaft 320. For example, the blade holders 330 can be slidably connected to the connecting shaft 320, and adjusting bolts can be inserted through the blade holders 330. The ends of the adjusting bolts press against the connecting shaft 320, thereby locking the blade holders 330 to the connecting shaft 320.

[0033] After prolonged use, the cutter 310 requires cooling to improve its service life and the slitting effect on the material strip. In this embodiment, the cutter holder 330 is provided with a cutter cover 350, which has an arc-shaped slot. One side of the cutter 310 extends into the arc-shaped slot. The outer side of the cutter cover 350 has a lubrication port 351 and a cleaning port 352 along the circumference of the cutter 310. During use, a flexible material such as a sponge or wool felt moistened with oil can be inserted into the lubrication port 351, and a clean sponge or wool felt can be inserted into the cleaning port 352. When the cutter 310 rotates, it is cooled and lubricated by the oil-soaked sponge or wool felt, and then cleaned by the clean sponge or wool felt. Finally, it passes through the material strip to slit it, thus effectively improving the slitting effect.

[0034] To reduce oil dripping from the cutter 310 and contaminating structures such as the cutter holder 330, a recovery tank is provided in the cutter holder 330 below the cutter 310 in this embodiment. Oil dripping from the cutter 310 is collected in the recovery tank, effectively reducing the possibility of oil flowing around and contaminating the machine body and conveyor belt.

[0035] like Figure 4As shown, this utility model also includes an unloading mechanism, which includes a movable frame 610 and a hook 620. The movable frame 610 is slidably disposed on the top side of the machine base 100. A translation device is provided between the machine base 100 and the movable frame 610. The translation device can drive the movable frame 610 to move in a direction perpendicular to the unwinding roller. A lifting device is provided on the movable frame 610. The lifting device is driven and connected to a lifting rod 641. The lifting device can drive the lifting rod 641 to move up and down. The hook 620 is disposed on the lifting rod 641. When it is necessary to replace the roll material on the unwinding roller, the translation device and the lifting device respectively provide driving force for the translation and up and down movement of the lifting rod, so that the hook 620 hangs the roll material. Then, the hook 620 loads the product onto the unwinding roller. In this way, the transfer and handling of the roll material is realized mechanically, reducing the labor intensity of workers and improving the overall operating efficiency and convenience.

[0036] The translation device is mainly used to provide driving force for the translational movement of the hook 620. It has various structural forms. In this embodiment, the translation device includes a first motor, a rack 631, and a gear 632. The first motor is mounted on the base 100 and drives the gear 632. The rack 631 is connected to the movable frame 610, and the gear 632 and rack 631 mesh with each other. When the movable hook 620 needs to be translated, the first motor drives the gear 632 to rotate. Utilizing the meshing of the gear 632 and rack 631, the movable frame 610 can be slidably moved on the base 100 via the rack 631, thus allowing the movable frame 610 to move stably. In this way, by driving the gear 632 to rotate forward or reverse, the first motor can move the hook 620 closer to or away from the unwinding roller.

[0037] The lifting device is mainly used to provide driving force for the hook 620 to move in the vertical direction. It has various structural forms. In this embodiment, the lifting device includes a second motor 642, a sprocket 643, and a chain 644. The movable frame 610 is provided with two sprockets 643 spaced apart in the vertical direction. The chain 644 is connected to the two sprockets 643. The second motor 642 is connected to the movable frame 610 and drives one of the sprockets 643. The lifting rod 641 is connected to one side of the chain 644. The second motor 642 can drive one of the sprockets 643 to rotate. Because the sprocket 643 and the chain 644 cooperate with each other, when the sprocket 643 rotates, it can drive the chain 644 to rotate between the two sprockets 643, thereby causing the lifting rod 641 connected to one side of the chain 644 to slide up and down. Thus, by driving the chain 644 to rotate forward or backward by the second motor 642, the hook 620 can move upward or downward.

[0038] The number of hooks 620 can be one, but in this embodiment, multiple hooks 620 are provided on the lifting rod 641. Multiple hooks 620 simultaneously suspend materials at different positions, which can improve the stability of the material's vertical movement. In practical applications, the number of hooks 620 can be configured according to the different suspension positions of the materials; for example, two hooks can be spaced apart along the length of the lifting rod 641.

[0039] In some embodiments, the base 100 is provided with a plurality of transition rollers 700 located between the unwinding roller and the take-up roller 500. The strip released from the unwinding roller is guided by the plurality of transition rollers 700 before being fed to the take-up roller 500. The plurality of transition rollers 700 can increase the tension of the strip when it is released.

[0040] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
