[0052] Please refer to Figure 2 The present embodiment provides a conveying mechanism of a paper cutter, comprising:

[0053] A first conveying belt 110, the first conveying belt is used to convey a paper sheet 200 at a first speed;

[0054] blowing devices 130, at least two groups, arranged at the output end of the first conveying belt 110, used to blow the paper sheet 200 at the output end of the first conveying belt 110;

[0055] a second conveying belt 120, connected to the output end of the first conveying belt 110, used to convey the paper sheet 200 at a second speed, the first speed being greater than the second speed;

[0056] a first vacuum device, the suction port of which is arranged between the first conveying belt 110 and the second conveying belt 120, used to form a first vacuum zone 140 between the first conveying belt 110 and the second conveying belt 120, and to suck the paper sheet 200 blown by the blowing device 130 to the second conveying belt 120;

[0057] a second vacuum device, the suction port of which is arranged at the input end of the second conveying belt 120, used to form a second vacuum zone 150 at the input end of the second conveying belt 120, and to suck the paper sheet 200 to the second conveying belt 120.

[0058] When the paper sheet 200 is conveyed on the conveying mechanism of the paper cutter, when the paper sheet 200 is conveyed by the first conveying belt 110, it is blown up by the blowing device 130 at the output end of the first conveying belt 110 when it reaches the output end of the first conveying belt 110, and at least two groups of blowing devices 130 can generate greater wind power to blow the paper sheet 200 to a higher position, thereby generating a gap with the paper sheet 200 in front that is vacuum-sucked, avoiding scratches there, and because the height of the paper sheet 200 is increased, the time for the paper sheet 200 to be transferred from the fast belt to the stacking area on the second conveying belt 120 is relatively extended, the speed of the paper sheet 200 when it finally contacts is reduced, and the probability of scratches is reduced; after the paper sheet 200 is blown up by the blowing device 130, the first vacuum device forms a first vacuum between the first conveying belt 110 and the second conveying belt 120, and sucks the paper sheet 200 blown up by the blowing device 130 to make it fall onto the second conveying belt 120, and the second vacuum device forms a second vacuum zone 150 at the input end of the second conveying belt 120, and sucks the paper sheet 200 to the second conveying belt 120, and the paper sheet 200 is driven by the second conveying belt 120, and can be slowed down by the second vacuum zone 150 without the paper sheet 200 being slowed down by the deceleration belt 160, avoiding scratches caused by the contact between the paper sheet 200 and the deceleration belt 160.

[0059] In some embodiments, the transmission belt of the second transmission belt 120 is a transmission net. By using a transmission net as the second transmission belt 120, the second vacuum area 150 can suck the paper sheet 200 onto the second transmission belt 120. In other embodiments, the second transmission belt 120 can also be composed of multiple transmission belts arranged at intervals, and the second vacuum area 150 can also suck the paper sheet 200 onto the second transmission belt 120 through the gaps on the second transmission belt 120.

[0060] Referring to Figure 3 In some embodiments, the blowing device 130 is at least two groups.

[0061] By using at least two groups of blowing devices 130, greater wind power can be generated to blow the paper sheet 200 to a higher position, thereby generating a gap with the paper sheet 200 in front that is sucked by the vacuum, avoiding scratches there. In addition, due to the increase in the height of the paper sheet 200, the time for the paper sheet 200 to transition from the first transmission belt 110 to the stacking area on the second transmission belt 120 is relatively extended, the speed of the paper sheet 200 when finally contacting is reduced, and the probability of scratches is reduced.

[0062] Referring to Figure 3 In some embodiments, the cutting machine further comprises:

[0063] A deceleration belt 160 is arranged above the output end of the first transmission belt 110 and the second transmission belt 120.

[0064] A deceleration press roller 170 is arranged on the deceleration belt 160.

[0065] In order to avoid the paper sheet 200 being blown too high by the blowing device 130 and being unable to be sucked by the first vacuum area 140, the deceleration belt 160 is arranged above the output end of the first transmission belt 110 and the second transmission belt 120. When the paper sheet 200 is blown to a higher position by the blowing device 130, the height of the paper sheet 200 being blown up is limited by the deceleration belt 160. The deceleration press roller 170 further decelerates the paper sheet 200 by pressing down the deceleration belt 160, so that the paper sheet 200 will not be blown to a higher position and will not be unable to be sucked by the first vacuum area 140. At the same time, due to the suction of the first vacuum area 140 and the second vacuum area 150, the paper sheet 200 will not stay on the deceleration belt 160 for a long time, and the deceleration belt 160 will reduce the scratches on the paper sheet 200 while decelerating the paper sheet 200.

[0066] In another embodiment, a cutting machine comprises a transmission mechanism, referring to Figure 2 The transmission mechanism comprises:

[0067] A first transmission belt 110 is used to transport the paper sheet 200 at a first speed.

[0068] blowing devices 130, at least two groups, arranged at the output end of the first conveying belt 110, used to blow the paper sheet 200 at the output end of the first conveying belt 110;

[0069] a second conveying belt 120, connected to the output end of the first conveying belt 110, used to convey the paper sheet 200 at a second speed, the first speed being greater than the second speed;

[0070] a first vacuum device, the suction port of which is arranged between the first conveying belt 110 and the second conveying belt 120, used to form a first vacuum zone 140 between the first conveying belt 110 and the second conveying belt 120, and to suck the paper sheet 200 blown by the blowing device 130 to the second conveying belt 120;

[0071] a second vacuum device, the suction port of which is arranged at the input end of the second conveying belt 120, used to form a second vacuum zone 150 at the input end of the second conveying belt 120, and to suck the paper sheet 200 to the second conveying belt 120.

[0072] When the paper sheet 200 is conveyed on the conveying mechanism of the paper cutter, when the paper sheet 200 is conveyed by the first conveying belt 110, it reaches the output end of the first conveying belt 110, and is blown up by the blowing device 130 at the output end of the first conveying belt 110. With at least two groups of blowing devices 130, greater wind power can be generated to blow the paper sheet 200 to a higher position, thereby creating a gap with the paper sheet 200 in front that is vacuum-sucked, avoiding scratches there, and because the height of the paper sheet 200 is increased, the time for the paper sheet 200 to transition from the fast belt to the stacking area on the second conveying belt 120 is relatively extended, the speed at which the paper sheet 200 finally contacts is reduced, and the probability of scratches is reduced. When the paper sheet 200 is blown up by the blowing device 130, the first vacuum device forms a first vacuum between the first conveying belt 110 and the second conveying belt 120, and sucks the paper sheet 200 blown up by the blowing device 130 to make it fall onto the second conveying belt 120. The second vacuum device forms a second vacuum zone 150 at the input end of the second conveying belt 120, and sucks the paper sheet 200 to the second conveying belt 120. The paper sheet 200 is driven by the second conveying belt 120, and can be slowed down without the deceleration belt 160 through the vacuum suction of the second vacuum zone 150, avoiding scratches caused by contact between the paper sheet 200 and the deceleration belt 160.

[0073] In some embodiments, the transmission belt of the second conveyor belt 120 is a conveying net. By using a conveying net as the second conveyor belt 120, the second vacuum area 150 can suck the paper sheet 200 onto the second conveyor belt 120. In other embodiments, the second conveyor belt 120 can also be composed of multiple transmission belts arranged at intervals, and the second vacuum area 150 can also suck the paper sheet 200 onto the second conveyor belt 120 through the gaps on the second conveyor belt 120.

[0074] Referring to Figure 3 In some embodiments, the blowing device 130 is at least two groups.

[0075] By using at least two groups of blowing devices 130, greater wind power can be generated to blow the paper sheet 200 to a higher position, thereby generating a gap with the paper sheet 200 in front that is sucked by the vacuum, avoiding scratches there. In addition, due to the increase in the height of the paper sheet 200, the time of the paper sheet 200 passing from the first conveyor belt 110 to the stacking area on the second conveyor belt 120 is relatively prolonged, and the speed of the paper sheet 200 when finally contacting is reduced, thereby reducing the probability of scratches.

[0076] Referring to Figure 3 In some embodiments, the transmission mechanism further comprises:

[0077] A deceleration belt 160 is arranged above the output end of the first conveyor belt 110 and the second conveyor belt 120;

[0078] A deceleration press wheel 170 is arranged on the deceleration belt 160.

[0079] In order to avoid the paper sheet 200 being blown by the blowing device 130 to a too high position and being unable to be sucked by the first vacuum area 140, the deceleration belt 160 is arranged above the output end of the first conveyor belt 110 and the second conveyor belt 120. When the paper sheet 200 is blown by the blowing device 130 to a higher position, the height of the paper sheet 200 being blown up is limited by the deceleration belt 160. The deceleration press wheel 170 further decelerates the paper sheet 200 by pressing down the deceleration belt 160, so that the paper sheet 200 will not be blown to a higher position and will not be unable to be sucked by the first vacuum area 140. At the same time, due to the suction of the first vacuum area 140 and the second vacuum area 150, the paper sheet 200 will not stay on the deceleration belt 160 for a long time, and the deceleration belt 160 will not scratch the paper sheet 200 while decelerating the paper sheet 200.

[0080] Finally, it should be noted that the above embodiments have been described in the specification and drawings of the application, but this does not limit the patent protection scope of the application. Any equivalent structure or equivalent process replacement or modification based on the essential concept of the application, using the content described in the specification and drawings of the application, and directly or indirectly implementing the technical solutions of the above embodiments in other related technical fields, etc., are all included in the patent protection scope of the application.
