DETAILED DESCRIPTION

[0019] The following is a more detailed description of the implementation of the utility model in conjunction with the drawings and the figure marks, so that those skilled in the art can implement it after reading this specification. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0020] The utility model provides Figure 1-4 The roll paper slitting device for effectively reducing the warpage shown in the figure comprises a frame 10 and an upper roll frame 20, a first anti-warpage device 30, a second anti-warpage device 40, a traction device 50, a paper cutting device 60, a conveying device 70 and a lifting paper receiving platform 80 which are sequentially arranged on the frame 10. The roll paper is placed on the upper roll frame 20 and can be rotated to pull out the paper; under the traction of the traction device 50, the paper is smoothed by the first anti-warpage device 30 and the second anti-warpage device 40, and then cut into flat paper by the paper cutting device 60, and then transported by the conveying device 70 to the lifting paper receiving platform 80 for temporary storage. The upper roll frame 20, the traction device 50, the paper cutting device 60, the conveying device 70 and the lifting paper receiving platform 80 can all refer to the relevant technology.

[0021] Please refer to Figure 1 The upper roll frame 20 includes a first upper roll frame 21 and a second upper roll frame 22, one for use and the other for backup. A front guide roller 24 is arranged between the first upper roll frame 21 and the first anti-warping device 30 to increase the tension of the paper when the paper enters the first anti-warping device 30. The roll paper on the first upper roll frame 21 enters the first anti-warping device 30 through the front guide roller 24. The second upper roll frame 22 is arranged at the bottom of the first anti-warping device 30, and a transition guide roller 23 is further arranged between the second upper roll frame 22 and the front guide roller 24 to increase the tension. The roll paper on the second upper roll frame 22 enters the first anti-warping device 30 through the transition guide roller 23 and the front guide roller 24 in sequence.

[0022] The first anti-warping device 30 and the second anti-warping device 40 each include a manual tension adjusting device 31, a middle guide roller 32, an electric tension adjusting device 33 and a rear guide roller 34 arranged in sequence. The transition guide roller, the front guide roller, the middle guide roller and the rear guide roller are all rotatably connected to the frame.

[0023] Specifically, the manual tension adjustment device 31 includes an anti-warping roller 311, two bearing seats 312 respectively connected to the two ends of the anti-warping roller 311, and a screw 313 threadedly connected to the bearing seat 312, and the screw 313 is perpendicular to the anti-warping roller 311; the frame 10 is provided with an axial positioning seat 314, the screw 313 is rotatably connected to the axial positioning seat 314, and a knob is provided at one end of the screw 313. The operator drives the screw to rotate through the knob to adjust the position of the anti-warping roller 311 relative to the front guide roller 24 and the middle guide roller 32, thereby adjusting the tension of the paper. Under the action of appropriate tension, the paper is smoothed when passing through the anti-warping roller 311. Furthermore, the installation height of the rear guide roller of the first anti-warping device 30 is higher than that of the middle guide roller of the second anti-warping device 40, so as to increase the adjustment range of the manual tension adjustment device of the second anti-warping device 40.

[0024] The electric tension adjustment device 33 includes a mounting seat 331, an anti-warping roller 332 rotatably connected to the mounting seat 331, two screw rods 333 respectively threadedly connected to the two ends of the mounting seat 331, a transmission shaft 334 transmission-connected to the screw rod 333, and a motor driving the transmission shaft 334 to rotate, wherein the screw rod 333 is perpendicular to the anti-warping roller 332; the frame 10 is provided with an axial positioning seat 335, wherein the screw rod 333 is rotationally connected to the axial positioning seat 335. The motor output shaft is connected to the transmission shaft 334 through a coupling, and the transmission shaft 334 is transmission-connected to the screw rod 333 through a bevel gear, so that the motor drives the screw rod to rotate, thereby changing the positions of the mounting seat 331 and the anti-warping roller 332 relative to the middle guide roller 32 and the rear guide roller 34, thereby adjusting the tension of the paper, and the paper is smoothed again when passing through the anti-warping roller 332. Preferably, the mounting seat 331 is also rotatably connected to a plurality of support wheels 336 , and the support wheels 336 are tangent to the anti-warping roller 332 to prevent the anti-warping roller 332 from deforming.

[0025] When in use, the electric tension adjustment device can be used to perform preliminary tension adjustment, and then the manual tension adjustment device can be used to perform secondary tension optimization, so as to achieve flexible regulation of paper tension. Under the action of appropriate tension, the paper is smoothed multiple times by the first anti-warping device 30 and the second anti-warping device 40, which can effectively reduce the warping degree of the paper.

[0026] The traction device 50 includes a lower roller, a motor for driving the lower roller to rotate, and an upper roller arranged above the lower roller. The upper roller is a rubber-coated roller with a thread groove on the surface, and the lower roller is a sandblasted steel roller. The paper is clamped between the upper and lower rollers, and the motor drives the lower roller to rotate, and the paper is pulled forward by friction and sent to the paper cutting device 60 to be cut into flat sheets, and the upper roller also rotates accordingly.

[0027] The conveying device 70 is used to convey flat paper, and includes a first belt conveyor 71 and a second belt conveyor 72 which are arranged in sequence. The height of the second belt conveyor 72 is lower than that of the first belt conveyor 71. By adjusting the speed difference between the two, the flat paper can be initially stacked on the second belt conveyor 72.

[0028] The lifting paper receiving platform 80 is arranged at the end of the conveying device 70 away from the paper cutting device 60. A hanging basket type reel lifting platform can be used. Flat sheets of paper are stacked on the lifting platform, and the platform height can be automatically lowered as the height of the paper stack increases. Paper beaters 81 are arranged on both sides of the top of the lifting paper receiving platform 80 and on the side away from the conveying device 70. The paper is stacked neatly in the lifting paper receiving platform 80 by reciprocatingly pushing the side of a stack of flat sheets of paper. Specifically, the paper beater 81 includes a cylinder 811 arranged on the frame 10 and a clapper 812 arranged on the output shaft of the cylinder 811. The cylinder 811 drives the clapper 812 to reciprocate to collect the staggered flat sheets of paper.

[0029] The above are one or more embodiments of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
