DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Reference Figure 1-Figure 5 The present embodiment provides a slitting and rewinding machine for plastic woven materials, comprising a first frame 1, on which a lower knife roller 2 is arranged, and on which a plurality of slitting mechanisms 4 are arranged through an upper knife roller 3 arranged parallel to the lower knife roller 2, and on which a rewinding roller 5 is arranged behind the lower knife roller 2 and the upper knife roller 3 on the first frame 1, and in front of the first frame 1 a second frame 7 is arranged through a base 6, and on which a rewinding roller 8 is arranged.

[0026] In the utility model, wide-width plastic woven material is released through the unwinding roller 8 of the second frame 7 on the base 6, and the released wide-width plastic woven material passes between the upper knife roller 3 and the lower knife roller 2 and then is rewound by the rewinding roller 5. When the plastic woven material passes through the upper knife roller 3 and the lower knife roller 2, the slitting mechanism 4 on the upper knife roller 3 slits the wide-width plastic woven material into narrow-width plastic woven material, and the narrow-width plastic woven material is rewound by the rewinding roller 5. The number of slitting mechanisms 4 on the upper knife roller 3 can be adjusted according to the slitting needs of the wide-width plastic woven material, thereby adjusting the narrow width, so that the slitting and rewinding machine can flexibly adapt to the slitting needs of materials of different widths and thicknesses.

[0027] Specifically, Figure 2 As shown, the slitting mechanism 4 includes a mounting plate 41 , which is fixedly connected to the upper knife roller 3 via a mounting assembly 42 , and a knife assembly 44 is disposed below the front end of the mounting plate 41 via a cylinder 43 .

[0028] Among them, the mounting plate 41 is connected to the upper knife roller 3 by means of the mounting assembly 42, so that the slitting mechanism 4 is fixed on the upper knife roller 3, and the tool assembly 44 is connected through the cylinder 43 to be able to perform the lifting and lowering adjustment of the tool assembly 44. When slitting wide plastic woven materials, the tool assembly 44 can be adjusted according to the thickness of the material, so that it can flexibly adapt to the slitting work of plastic woven materials of different thicknesses.

[0029] Specifically, Figure 2 and Figure 3 As shown, the mounting assembly 42 includes a connecting seat 421 arranged at the bottom of the mounting plate 41, the bottom of the connecting seat 421 is recessed upward to form a slot 422, bolt seats 423 are arranged on both sides of the connecting seat 421, and a clamping plate 424 is arranged at the bottom of the connecting seat 421 to cooperate with the slot 422 to form a circular hole groove, and a connecting bolt 425 that cooperates with the bolt seat 423 is arranged on the clamping plate 424.

[0030] Among them, when installing the slitting mechanism 4, the slot 422 of the connecting seat 421 is stuck on the upper knife roller 3, and then the clamping plate 424 is attached to the bottom of the connecting seat 421, and the clamping plate 424 is connected and fixed to the bolt seat 423 of the connecting seat 421 through the connecting bolt 425, so that the connecting seat 421 and the clamping plate 424 are clamped and fixed on the upper knife roller 3, thereby realizing the installation and fixation of the slitting mechanism 4 on the upper knife roller 3.

[0031] Specifically, Figure 2 and Figure 3 As shown, a plug plate 426 with a wedge-shaped top is provided on the clamping plate 424 , and a plug hole 427 matching with the plug plate 426 is provided on the bolt seat 423 .

[0032] Among them, when installing the installation component 42 and the upper knife roller 3, the clamping plate 424 is attached to the bottom of the connecting seat 421, and the plug plate 426 of the clamping plate 424 passes through the insertion hole 427. Since the plate-shaped plug plate 426 has a certain elasticity, when the plug plate 426 passes through, the plug plate 426 will be squeezed and bent backward due to the wedge-shaped structure on the top. When the plug plate 426 completely passes through the insertion hole 427 of the bolt seat 423, the plug plate 426 is reset, so that the wedge block on the top of the plug plate 426 is against the top of the bolt seat 423. The clamping plate 424 and the connecting seat 421 are fixed first through the cooperation of the plug plate 426 and the insertion hole 427. The operator can quickly complete the initial fixation and then focus on the tightening of the bolts, saving the overall installation time.

[0033] Specifically, Figure 2-Figure 4 As shown, the upper knife roller 3 is provided with a plurality of positioning holes 31 evenly arranged along its length direction, and the two ends of the upper knife roller 3 are fixedly connected with connecting ends 32, and the slot 422 and the clamping plate 424 are both provided with positioning strips 428 that match the positioning holes 31.

[0034] The positioning and limiting of the slitting mechanism 4 and the upper knife roller 3 are achieved by the positioning strip 428 and the positioning hole 31. When the connecting seat 421 and the clamping plate 424 are clamped on the upper knife roller 3, the positioning strip 428 on the clamping groove 422 of the connecting seat 421 and the positioning strip 428 on the clamping plate 424 are clamped in the positioning hole 31 of the upper knife roller 3. On the one hand, the stable installation of the slitting mechanism 4 on the upper knife roller 3 can be ensured, and on the other hand, the slitting mechanism 4 can be prevented from rotating on the upper knife roller 3 to affect the slitting work.

[0035] It should be noted that there are several positioning holes 31 and they are arranged along the length direction of the upper knife roller 3. Through several positioning holes 31, different numbers of slitting mechanisms 4 can be installed, which can flexibly adapt to the slitting needs of materials of different widths and thicknesses. Whether it is wide-width material or narrow-width material, precise slitting can be achieved by adjusting the number of slitting mechanisms 4.

[0036] The slot 422 and the clamping plate 424 are both provided with rubber pads 429. The rubber pads 429 play a buffering role on the one hand, making the slitting mechanism 4 more stable when the upper knife roller 3 is installed, and on the other hand, play an anti-skid role to prevent the slitting mechanism 4 and the upper knife roller 3 from sliding relative to each other, thereby improving the accuracy of the slitting mechanism 4 during slitting.

[0037] Specifically, Figure 2 and Figure 5 As shown, the tool assembly 44 includes a tool seat 441 located at the output end of the cylinder 43, a blade 443 is arranged on the tool seat 441 through a connecting shaft 442, a connecting hole 444 matching with the connecting shaft 442 is opened in the middle position of the blade 443, and a nut 448 abutting against the blade 443 is arranged at one end of the connecting shaft 442 away from the tool seat 441 through a screw rod 447.

[0038] When installing the blade 443, align the connecting hole 444 with the connecting shaft 442, and then screw the nut 448 onto the screw 447 at one end of the connecting shaft 442, so that the blade 443 can be connected to the connecting shaft 442 of the blade holder 441. While ensuring that the blade 443 is stably installed on the blade holder 441, it is convenient for the installation and disassembly of the blade 443, so that the blade 443 can be easily disassembled and repaired.

[0039] It should be noted that the connecting shaft 442 is provided with a plurality of limit blocks 445 arranged along the length direction thereof, and the connecting hole 444 is provided with a limit groove 446 that matches the limit block 445. The cooperation between the limit block 445 and the limit groove 446 can prevent the blade 443 and the connecting shaft 442 from sliding relative to each other, thereby preventing wear between the blade 443 and the connecting shaft 442 and extending the service life of the blade 443.

[0040] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
