[0035] Reference Figure 1-Figure 6 According to an embodiment of a friction traction slitting machine of the utility model, it includes a frame 11, in which an unwinding component 101, a traction component 102, a slitting component 103 and a winding component 104 are arranged.

[0036] The traction assembly is used to pull the material unwound by the unwinding assembly so that the material has a transition during the unwinding and rewinding process to avoid excessive stretching. The traction assembly includes two large-diameter shafts 13 that are rotatably connected to the frame 11 and arranged on the left and right. The frame 11 is also equipped with a No. 1 motor for driving the large-diameter shaft 13 to rotate, and also includes a clamping shaft 14 and an adjustable clamping mechanism for controlling the distance between the clamping shaft 14 and the large-diameter shaft 13.

[0037] In this embodiment, the diameter of the large diameter shaft 13 is 200 mm, so that the friction traction slitting machine has two traction modes:

[0038] One is that the pressing shaft 14 is away from the large diameter shaft 13, and the material is unwound by the unwinding assembly, and then wound around the No. 1 rotating shaft 91 between the frames 11, and then wound around the lower curved surface of the large diameter shaft 13 on the right, and then wound around the upper curved surface of the large diameter shaft 13 on the left, and then enters the slitting assembly, such as Figure 4 As shown, during this process, the large diameter shaft 13 actively rotates, and relies on the friction between the material and the curved surface of the large diameter shaft 13 to pull the material.

[0039] Secondly, the pressing shaft 14 is attached to the large diameter shaft 13 on the right side to press the material onto the large diameter shaft 13 , and at this time, the material can be pulled by the rotation of the large diameter shaft 13 .

[0040] Some materials that are easily deformed under the influence of the clamping shaft 14 are suitable for the first traction method mentioned above. The setting of this traction method in the friction traction slitting machine increases the scope of application and can pull thinner and more easily deformed materials with less influence.

[0041] The adjustable clamping mechanism includes two mounting plates 15 which are hinged in the frame 11 and distributed front and back. The clamping shaft 14 is rotatably connected between the two mounting plates 15. A No. 1 cylinder 16 is also hinged in the frame 11. A No. 1 piston rod in the No. 1 cylinder 16 is hinged on the mounting plate 15. That is, the staff can control the distance between the clamping shaft 14 and the large diameter shaft 13 by controlling the No. 1 cylinder 16.

[0042] In addition, in this embodiment, the slitting assembly is located at the lower side of the traction assembly, and the slitting assembly includes two slitting rollers 21 rotatably connected to the frame 11, the two slitting rollers 21 are respectively equipped with an upper knife and a lower knife, the two slitting rollers 21 are connected by a gear set, and the frame 11 is equipped with a No. 2 motor for driving the slitting rollers 21 to rotate.

[0043] It also includes an adjusting roller 22 that can be adjusted left and right, and the adjusting roller 22 is located between the slitting assembly and the traction assembly.

[0044] A second rotating shaft 92 is also rotatably connected between the frame 11 on the lower side of the slitting roller 21. The material pulled by the traction assembly will stick to the adjusting roller 22 and then enter between the slitting rollers 21 and be slit. After that, the material will wrap around the No. 2 rotating shaft 92 and enter the winding assembly. Since the adjusting roller 22 can be adjusted left and right, the angle of the material when entering the slitting roller 21 can be adjusted to minimize the wrap angle between the material and the slitting roller 21 (lower knife), and minimize the bending and wrinkles formed by the material wrapping around the slitting roller 21 and after cutting, thereby improving product quality.

[0045] The mounting method of the adjusting roller 22 is as follows: two mounting seats 23 distributed front and back are installed in the frame 11, and an adjusting block is slidably connected to the mounting seat 23 from left to right, and the adjusting roller 22 is rotatably connected between the two adjusting blocks, and an adjusting shaft 25 threadedly connected to the mounting seat 23 is rotatably connected in the mounting seat 23;

[0046] It also includes a pressure plate 26 fixed to the mounting seat 23 by screws to press the adjusting shaft 25, that is, the staff can rotate the adjusting shaft 25 to control the left and right positions of the adjusting block and the adjusting roller 22, and after the adjustment is completed, the staff can install the pressure plate 26 to press the adjusting shaft 25, and the position of the adjusting shaft 25 is locked.

[0047] The winding assembly includes two winding rollers 31 which are rotatably connected to the frame 11 and are distributed up and down. A No. 3 motor for driving the winding rollers 31 is installed in the frame 11.

[0048] In addition, a clamping mechanism is included, and two clamping mechanisms are provided, and they act on the materials outside the two winding rollers 31 respectively;

[0049] Each of the clamping mechanisms includes two hinged plates 32 that are hinged in the frame 11 and distributed front and back, and a pressure roller 33 is rotatably connected between the front and rear hinged plates 32. A No. 2 cylinder 34 is also hinged in the frame 11, and a No. 2 piston rod in the No. 2 cylinder 34 is hinged to the hinged plate 32 to control the angle of the hinged plate 32.

[0050] In addition, a guide roller 35 is rotatably connected between the front and rear hinged plates 32, and a No. 3 cylinder 36 is provided on the hinged plate 32. A lifting platform 37 is installed on the No. 3 piston rod in the No. 3 cylinder 36, and a locking roller 38 is installed between the front and rear lifting platforms 37, and the locking roller 38 can be pressed on the guide roller 35.

[0051] The material that has passed through the No. 2 rotating shaft 92 and has been cut will be wound around the guide roller 35 and the pressure roller 33 and then rolled outside the two winding rollers 31. When the material outside the winding roller 31 is rolled and needs to be unloaded, the winding roller 31 stops rotating, and the staff controls the hinge plate 32 to rotate until the pressure roller 33 is pressed on the outer curved surface of the rolled material to prevent it from scattering. Then the No. 3 cylinder 36 controls the lifting platform 37 to sink until the material is clamped between the locking roller 38 and the guide roller 35, and at this time the staff can cut the material between the guide roller 35 and the pressure roller 33, and then the hinge plate 32 is lifted to facilitate unloading, and when the unloading is completed and the material needs to be rewound around the pressure roller 33, the No. 3 cylinder 36 can lift the lifting platform 37 upwards, and at this time the material is unlocked and can be rewound around the winding roller 31 to facilitate operation.

[0052] In the second embodiment of the friction traction slitting machine, an automatic unloading device 105 is further included. In order to achieve the docking of the two winding rollers 31 with the two unloading shafts in the automatic unloading device, the winding roller 31 is installed in such a way that the rear end of the winding roller 31 is rotatably connected to the frame 11, and a bearing is installed at the front edge of the outer curved surface of the winding roller 31;

[0053] The frame 11 is hinged with two support plates 39 distributed up and down and used to support the two winding rollers 31 respectively. The support plates 39 are provided with grooves for accommodating the bearings, and the frame 11 is equipped with a No. 4 cylinder for controlling the angle of the support plates 39.

[0054] It also includes a locking plate 40 that can be pressed on the outer curved surface of the bearing, and a No. 5 cylinder 41 for controlling the position of the locking plate 40 is installed on the support plate 39.

[0055] During normal winding, the locking plate 40 presses the bearing into the groove so that the winding roller 31 supported by the support plate 39 maintains stable rotation. During unloading, the two winding rollers 31 are docked with the two unloading shafts in the automatic unloading device, and then the support plate 39 swings downward to avoid interfering with the forward movement of the material roll on the winding roller 31.

[0056] In order to enable the material roll to automatically move forward into the automatic unloading device, a controlled plate 42 is also slidably connected to the frame 11, and a No. 4 motor is installed in the frame 11 for driving the controlled plate 42 to move forward and backward. Two push plates 43 distributed up and down are provided on the controlled plate 42, and an arc groove is provided in the push plate 43 for accommodating part of the winding roller 31, so that the stripping plate 43 can contact the material roll with a larger area.

[0057] It should be additionally explained that the unwinding device is used to support the material roll for unwinding, which is the prior art and will not be described in detail here. The automatic unloading device is used to receive the material roll on the winding roller 31, which will not be described in detail here, and reference can be made to the automatic unloading device of a slitting machine with application number 202321691257.7, and the winding roller 31 can be an inflatable shaft.

[0058] The above description is only a specific embodiment of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by any technician in the field of the present invention are included in the patent scope of the present invention.
