[0020] See also Figures 1 to 3 The paper processing and conveying cutting equipment includes a cutting mechanism 200, a sorting mechanism 100 and a conveying mechanism 300.

[0021] The cutting mechanism 200 is arranged at the first station, and the cutting mechanism 200 can cut multiple papers 900 at the same time; the sorting mechanism 100 can transfer the cut paper 900 from the first station to the conveying mechanism 300 at the second station, and the conveying mechanism 300 can transport the paper 900 to the next process.

[0022] See also Figure 1 In some embodiments, the paper processing conveying and cutting equipment also includes a slitting mechanism 500 and a moving mechanism. The slitting mechanism 500 can cut the entire sheet of paper 900 into multiple strips along the length direction of the paper, and the moving mechanism can transport the multiple strips of paper 900 after cutting to the first workstation for easy cutting by the cutting mechanism 200.

[0023] See also Figure 1 In some embodiments, the paper processing conveying and cutting device further includes a frame 400 , and the slitting mechanism 500 , the moving mechanism, the cutting mechanism 200 and the sorting mechanism 100 are respectively arranged on the frame 400 .

[0024] See also Figure 2 and Figure 3 In some embodiments, the cutting mechanism 200 includes a cutter 210 and a support plate 220. The support plate 220 is fixed to the frame 400 and is located above the finishing mechanism 100. The cutter 210 is movably mounted on the frame 400. The moving mechanism can simultaneously transport multiple strips of paper 900 to the upper surface of the support plate 220. The cutter 210 can simultaneously cut the multiple strips of paper 900 by moving in a vertical downward direction. The support plate 220 can support one end of the paper 900 while the cutter 210 is cutting the paper 900.

[0025] Preferably, the cutter 210 cuts along the width direction of the paper 900 .

[0026] See also Figure 5 and Figure 6 The sorting mechanism 100 includes a plurality of first rollers 110 and a plurality of second rollers 120. The axial direction of the first roller 110 is the same as the axial direction of the second roller 120. The plurality of first rollers 110 and the plurality of second rollers 120 are connected in sequence at intervals so that the plurality of first rollers 110 and the plurality of second rollers 120 can rotate synchronously.

[0027] The outer diameter of the first roller 110 is larger than the outer diameter of the second roller 120. A first inclined member 111 is provided on the first roller 110, and a second inclined member 121 is provided on the second roller 120. The slope of the upper surface of the first inclined member 111 is smaller than the slope of the upper surface of the second inclined member 121. As a result, first limiting portions 113 are formed on both sides of the front end of the first roller 110 along the axial direction of the first roller 110, and second limiting portions 123 are formed on both sides of the rear end of the second roller 120 along the axial direction of the second roller 120. When the first roller 110 and the second roller 120 drive the corresponding paper 900 to move from the first station to the second station, the second limiting portions 123 can limit the movement of the paper 900 on the first inclined member 111, and the first limiting portions 113 can limit the movement of the paper 900 on the second inclined member 121.

[0028] It should be noted that, when the first inclined member 111 moves from the first station to the second station, the end that first approaches the second station is defined as the front end of the first inclined member 111, and the end that later approaches the second station is defined as the rear end of the first inclined member 111; when the second inclined member 121 moves from the first station to the second station, the end that first approaches the second station is defined as the front end of the second inclined member 121, and the end that later approaches the second station is defined as the rear end of the second inclined member 121.

[0029] Since the outer diameter of the first roller 110 is larger than the outer diameter of the second roller 120, and the inclination of the upper surface of the first inclined member 111 is smaller than the inclination of the upper surface of the second inclined member 121, before the paper 900 completely falls onto the second inclined member 121, the first limiting portion 113 on the first inclined member 111 adjacent to the second inclined member 121 can limit the movement of the front end of the paper 900 along the axial direction of the first roller 110, so as to ensure that the paper 900 accurately falls onto the upper surface of the first inclined member 111, and before the paper 900 completely falls onto the first inclined member 111, the second limiting portion 123 on the second inclined member 121 adjacent to the first inclined member 111 can limit the movement of the rear end of the paper 900 along the axial direction of the first roller 110, so as to ensure that the paper 900 accurately falls onto the upper surface of the second inclined member 121.

[0030] The first inclined member 111 and the second inclined member 121 can carry and drive the corresponding paper 900 to move from the cutting mechanism 200 to the conveying mechanism 300. During the movement, the first limiting portion 113 and the second limiting portion 123 can still prevent the corresponding paper 900 from deviating, thereby ensuring that the landing point of the paper 900 on the conveying mechanism 300 is consistent, and preventing the paper 900 from being misplaced and stacked on the conveying mechanism 300.

[0031] Furthermore, the shape of the upper surface of the first inclined member 111 is adapted to the shape of the paper 900 , and the shape of the upper surface of the second inclined member 121 is adapted to the shape of the paper 900 .

[0032] It is worth noting that the support plate 220 is located above the first roller 110 and the second roller 120. When the cutter 210 moves in the vertical downward direction, it will exceed the height of the upper surface of the support plate 220, but will not exceed the height of the lower surface of the support plate 220 to prevent interference between the cutter 210 and the first roller 110 or the second roller 120.

[0033] The first inclined member 111 is provided with a first baffle 112 along the axial direction of the first roller 110, and the second inclined member 121 is provided with a second baffle 122 along the axial direction of the second roller 120. The first baffle 112 is capable of limiting the movement of the paper 900 on the first inclined member 111, thereby preventing the paper 900 from falling off the first inclined member 111 during the process of being transferred from the first station to the second station by the first inclined member 111. The second baffle 122 is capable of limiting the movement of the paper 900 on the second inclined member 121, thereby preventing the paper 900 from falling off the second inclined member 121 during the process of being transferred from the first station to the second station by the second inclined member 121.

[0034] The two adjacent first baffles 112 can limit the movement of the front end of the paper 900 along the axial direction of the first roller 110 , thereby ensuring that the paper 900 accurately falls onto the upper surface of the second inclined member 121 .

[0035] See also Figure 3 and Figure 5 In some embodiments, the length of the first inclined member 111 is the same as the length of the second inclined member 121, and the first baffle 112 on the adjacent first inclined member 111 and the second baffle 122 on the second inclined member 121 are staggered. The second baffle 122 approaches the conveying mechanism 300 earlier than the first baffle 112. When the cutter 210 cuts the paper 900, the maximum height of the rear end of the upper surface of the first inclined member 111 supporting the paper 900 and the maximum height of the rear end of the upper surface of the second inclined member 121 supporting the paper 900 are both the same as the height of the upper surface of the support plate 220. When the paper 900 is cut by the cutter 210, the front and rear ends of the paper 900 are respectively supported, thereby improving the cutting effect of the paper 900.

[0036] See also Figure 5 In some embodiments, each first roller 110 is provided with a plurality of first inclined members 111, and the plurality of first inclined members 111 are arranged at intervals along the circumferential direction of the first roller 110; each second roller 120 is provided with a plurality of second inclined members 121, and the plurality of second inclined members 121 are arranged at intervals along the circumferential direction of the second roller 120.

[0037] See also Figure 2 and Figure 5 In some embodiments, the plurality of first rollers 110 and the plurality of second rollers 120 are sequentially spaced apart and connected by a bolt structure, so that the plurality of first rollers 110 and the plurality of second rollers 120 can rotate synchronously.

[0038] See also Figure 2 In some embodiments, the finishing mechanism 100 further includes an end cover 130 , which is connected to the outer side of a first roller 110 . The end cover 130 can drive the multiple first rollers 110 and the multiple second rollers 120 to rotate synchronously.

[0039] Illustratively, the end cover 130 is fixed to the outer side of the first roller 110 by a bolt structure.

[0040] See also Figure 1 In some embodiments, the paper processing conveying and cutting device further includes a driving mechanism 600 , which can drive the end cover 130 to rotate.

[0041] Exemplarily, the driving mechanism 600 is a crawler drive, and the driving mechanism 600 includes a motor, a crawler and a rotating disk; one end of the end cover 130 is rotatably provided on the frame 400 and connected to the rotating disk, one end of the crawler is sleeved on the rotating disk, and the other end is sleeved on the driving end of the motor. The driving end of the motor drives the crawler to rotate, so that the crawler can drive the rotating disk to rotate, thereby causing the rotating disk to drive the end cover 130 to rotate, and then drive the multiple first rollers 110 and the multiple second rollers 120 to rotate synchronously.

[0042] See also Figure 5 、 Figure 6 and Figure 8 In some embodiments, the paper processing conveying and cutting equipment further includes a negative pressure cylinder 150, a plurality of first rollers 110 and a plurality of second rollers 120 are rotatably disposed on the negative pressure cylinder 150, and a first negative pressure chamber 151, a second negative pressure chamber 152 and a third negative pressure chamber 153 are respectively provided in the negative pressure cylinder 150, a plurality of first through holes 1111 and a plurality of second through holes 1112 are provided on the first inclined member 111, and a plurality of third through holes 1211 and a plurality of fourth through holes 1212 are provided on the second inclined member 121.

[0043] During the rotation stroke of the first roller 110 and the second roller 120 from the first station to the second station, the first through hole 1111 can be connected to the second negative pressure chamber 152 and the third negative pressure chamber 153 in sequence, the second through hole 1112 can be connected to the first negative pressure chamber 151 and the second negative pressure chamber 152 in sequence, the third through hole 1211 can be connected to the first negative pressure chamber 151, the second negative pressure chamber 152 and the third negative pressure chamber 153 in sequence, and the fourth through hole 1212 can be connected to the second negative pressure chamber 152, so that the paper 900 on the first inclined member 111 can be adsorbed on the upper surface of the first inclined member 111, and the paper 900 on the second inclined member 121 can be adsorbed on the upper surface of the second inclined member 121, thereby preventing the paper 900 from falling off the first inclined member 111 or the second inclined member 121 when moving from the first station to the second station.

[0044] See also Figure 6 In some embodiments, multiple first through holes 1111 are opened at the front end of the first inclined member 111, multiple second through holes 1112 are opened at the rear end of the first inclined member 111, multiple third through holes 1211 are opened at the front end of the second inclined member 121, and multiple fourth through holes 1212 are opened at the rear end of the second inclined member 121.

[0045] After the paper 900 is cut by the cutter 210, the rear end of the paper 900 that falls on the first inclined member 111 can be adsorbed to the upper surface of the first inclined member 111 by the negative pressure in the second through hole 1112, thereby preventing the paper 900 from falling off the first inclined member 111. The front end of the paper 900 that falls on the second inclined member 121 can be adsorbed to the upper surface of the second inclined member 121 by the negative pressure in the third through hole 1211, thereby preventing the paper 900 from falling off the second inclined member 121.

[0046] When the first inclined member 111 and the second inclined member 121 drive the corresponding paper 900 to gradually move toward the second workstation, the paper 900 on the first inclined member 111 can be adsorbed on the upper surface of the first inclined member 111 through the negative pressure in the first through hole 1111 and the second through hole 1112, and the paper 900 on the second inclined member 121 can be adsorbed on the upper surface of the second inclined member 121 through the negative pressure in the third through hole 1211 and the fourth through hole 1212.

[0047] When the first inclined member 111 and the second inclined member 121 drive the corresponding paper 900 to approach the second workstation, the front end of the paper 900 on the first inclined member 111 can be adsorbed to the upper surface of the first inclined member 111 through the negative pressure in the first through hole 1111, and the front end of the paper 900 on the second inclined member 121 can be adsorbed to the upper surface of the second inclined member 121 through the negative pressure in the third through hole 1211.

[0048] See also Figure 6 、 Figure 8 and Figure 9 In some embodiments, a plurality of first communicating grooves 1511 and a plurality of second communicating grooves 1512 are formed on the inner wall of the first negative pressure chamber 151, the first communicating grooves 1511 are used to connect the first negative pressure chamber 151 and the third through hole 1211, and the second communicating grooves 1512 are used to connect the first negative pressure chamber 151 and the second through hole 1112; an opening 1521 is formed on the inner wall of the second negative pressure chamber 152, the opening 1521 is used to connect the first through hole 1111, the second through hole 1112, the third through hole 1211 and the fourth through hole 1212 with the second negative pressure chamber 152; a plurality of third communicating grooves 1531 are formed on the inner wall of the third negative pressure chamber 153, a part of the third communicating grooves 1531 are used to connect the third negative pressure chamber 153 and the first through hole 1111, and another part of the third communicating grooves 1531 are used to connect the third negative pressure chamber 153 and the third through hole 1211.

[0049] See also Figure 6 and Figure 9In some embodiments, the plurality of first communicating grooves 1511 corresponding to a single second inclined member 121 are divided into two rows, the plurality of first communicating grooves 1511 in each row are arranged at intervals along the circumference of the negative pressure cylinder 150, and the two first communicating grooves 1511 adjacent to each other in the axial direction of the negative pressure cylinder 150 are staggered, and the plurality of third through holes 1211 on each second inclined member 121 are divided into at least two rows, the plurality of third through holes 1211 in each row are arranged at intervals along the circumference of the negative pressure cylinder 150, so that the second inclined member 121 is arranged at intervals along the circumference of the negative pressure cylinder 150. During circumferential rotation, the two rows of third through holes 1211 along the axial direction of the second roller 120 can alternately connect with the corresponding first connecting grooves 1511, thereby causing the left and right sides of the paper 900 to be alternately attracted to the second inclined member 121. This alternating attraction prevents warping of the left and right sides of the paper 900. Furthermore, the vibration generated by the alternating attraction can also regulate the deviation of the front end of the paper 900, thereby preventing the front end of the paper 900 from deviating along the axial direction of the first roller 110. When the front end of the paper 900 completely lands on the second inclined member 121, the alternating attraction of the third through holes 1211 and the first stopper 113 effectively prevent the front end of the paper 900 from deviating.

[0050] It is worth noting that the left and right sides of the paper 900 refer to the two sides of the paper 900 along the axial direction of the first roller 110 .

[0051] See also Figure 6 and Figure 9 In some embodiments, the plurality of second communicating grooves 1512 corresponding to a single first inclined member 111 are divided into two columns, the plurality of second communicating grooves 1512 in each column are arranged at intervals along the circumference of the negative pressure cylinder 150, and the two second communicating grooves 1512 adjacent to each other in the axial direction of the negative pressure cylinder 150 are staggered, and the plurality of second through holes 1112 on each first inclined member 111 are divided into at least two columns, the plurality of second through holes 1112 in each column are arranged at intervals along the circumference of the negative pressure cylinder 150, so that the first roller 110 is arranged at intervals along the circumference of the negative pressure cylinder 150. When the paper 900 rotates in the axial direction of the first roller 110, the two rows of second through holes 1112 can alternately connect with the corresponding second connecting grooves 1512, thereby causing the left and right sides of the paper 900 to be alternately attracted to the first inclined member 111. This alternating attraction can prevent the left and right sides of the paper 900 from warping. The vibration generated by the alternating attraction can also regulate the deviation of the rear end of the paper 900, thereby preventing the rear end of the paper 900 from deviating along the axial direction of the first roller 110. When the rear end of the paper 900 completely falls onto the first inclined member 111, the alternating attraction of the second through holes 1112 and the second stopper 123 effectively prevent the rear end of the paper 900 from deviating.

[0052] See also Figure 4 and Figure 9 In some embodiments, the plurality of third communication grooves 1531 corresponding to a single first inclined member 111 or a single second inclined member 121 are divided into two rows, and each row of third communication grooves 1531 extends in the circumferential direction of the negative pressure cylinder 150. The plurality of third through holes 1211 on each second inclined member 121 are divided into at least two rows, and the plurality of third through holes 1211 in each row are spaced apart along the circumference of the negative pressure cylinder 150. The plurality of first through holes 1111 on each first inclined member 111 are divided into at least two rows, and the plurality of first through holes 1111 in each row are spaced apart along the circumference of the negative pressure cylinder 150. When the first inclined member 111 or the second inclined member 121 rotates to the vicinity of the third negative pressure chamber 153, the left and right sides of the front end of the paper 900 can be attracted to the first inclined member 111 or the second inclined member 121.

[0053] See also Figure 6 and Figure 9 In some embodiments, the multiple third through holes 1211 on each second inclined member 121 are divided into at least three columns, two of which can be connected to the first connecting groove 1511 or the third connecting groove 1531, and each column can be connected to the opening 1521 to improve the adsorption force of the second inclined member 121 on the paper 900 when it is at the opening 1521.

[0054] Furthermore, the plurality of fourth through holes 1212 on each second inclined member 121 are divided into a plurality of columns, and each column of fourth through holes 1212 is staggered with each column of third through holes 1211 so that the fourth through holes 1212 are not connected to the first communicating groove 1511 and the second communicating groove 1512 .

[0055] See also Figure 6 and Figure 9 In some embodiments, the multiple second through holes 1112 on each first inclined member 111 are divided into at least three columns, two of which can be connected to the second connecting groove 1512 or the third connecting groove 1531, and each column can be connected to the opening 1521 to improve the adsorption force of the first inclined member 111 on the paper 900 when it is at the opening 1521.

[0056] Furthermore, the multiple first through holes 1111 on each first inclined member 111 are divided into at least two columns, and each column of first through holes 1111 and each column of second through holes 1112 are staggered so that the first through holes 1111 are not connected to the second communicating grooves 1512 .

[0057] In some embodiments, see Figure 9A plurality of fourth communicating grooves 1522 are provided on the inner wall of the second negative pressure chamber 152. The fourth communicating grooves 1522 are used to connect the second negative pressure chamber 152 and the third negative pressure chamber 153, so that the pressure in the second negative pressure chamber 152 and the pressure in the third negative pressure chamber 153 are the same, and the pressure in the second negative pressure chamber 152 and the pressure in the third negative pressure chamber 153 are lower than the pressure in the first negative pressure chamber 151, so that the paper 900 can detach from the first inclined member 111 or the second inclined member 121 and fall onto the conveying mechanism 300.

[0058] In some embodiments, see Figures 7 to 9 The sorting mechanism 100 also includes a negative pressure tube 140, and the negative pressure cylinder 150 has a cavity 154. The negative pressure tube 140 is arranged in the cavity 154. The negative pressure tube 140 has a first chamber and a second chamber separated from each other. The first chamber is connected to the first negative pressure cavity 151, and the second chamber is connected to the third negative pressure cavity 153. The pressure in the first chamber is greater than the pressure in the second chamber.

[0059] Illustratively, a partition is provided in the negative pressure tube 140 , and the partition is used to separate the first chamber from the second chamber.

[0060] In some embodiments, see Figure 1 and Figure 2 The paper processing conveying and cutting equipment also includes a first vacuum mechanism 700 and a second vacuum mechanism 800. One end of the negative pressure tube 140 is passed through the end cover 130 and the frame 400, and the negative pressure tube 140 is provided with a first joint 141 and a second joint 142. The first joint 141 corresponds to the first chamber and is connected to the first vacuum mechanism 700. The second joint 142 corresponds to the second chamber and is connected to the second vacuum mechanism 800. The first vacuum mechanism 700 is used to provide negative pressure to the first chamber, and the second vacuum mechanism 800 is used to provide negative pressure to the second chamber.

[0061] Illustratively, the first vacuum mechanism 700 and the second vacuum mechanism 800 are both vacuum pumps.

[0062] See also Figure 1 and Figure 4 In some embodiments, the conveying mechanism 300 includes a support frame 310, a conveyor belt 320 and a vacuum generator (not shown). The conveyor belt 320 is rotatably disposed on the support frame 310, and one end of the conveyor belt 320 is disposed at the second workstation. The vacuum generator is disposed in the conveyor belt 320. When the vacuum generator is operated, the paper 900 that falls onto the conveyor belt 320 is adsorbed on the conveyor belt 320.

[0063] Preferably, a plurality of adsorption holes are provided on the conveyor belt 320, and the vacuum generating element is a vacuum pump.

[0064] In some embodiments, the working process of the paper processing conveying and cutting device is as follows: In the first step, the slitting mechanism 500 slits the entire sheet of paper 900 so that the paper 900 is cut into multiple strips.

[0065] In the second step, the moving mechanism transports the cut pieces of paper 900 to the first workstation.

[0066] In the third step, the cutter 210 of the cutting mechanism 200 cuts the multiple papers 900 simultaneously at the first station.

[0067] In the fourth step, the arranging mechanism 100 arranges the cut paper 900 and drives the paper 900 to move from the first station to the second station.

[0068] When the first inclined member 111 and the second inclined member 121 drive the paper 900 to move to the first negative pressure chamber 151, the rear end of the paper 900 on the first inclined member 111 is attracted to the first inclined member 111, and the front end of the paper 900 on the second inclined member 121 is attracted to the second inclined member 121. When the first inclined member 111 and the second inclined member 121 drive the paper 900 to move to the second negative pressure chamber 152, both the front and rear ends of the paper 900 on the first inclined member 111 are attracted to the first inclined member 111, and both the front and rear ends of the paper 900 on the second inclined member 121 are attracted to the second inclined member 121. When the first and second inclined members 111, 121 move the paper 900 toward the third negative pressure chamber 153, the front end of the paper 900 is attracted to the first inclined member 111, allowing the rear end to hang freely. Similarly, the front end of the paper 900 is attracted to the second inclined member 121, allowing the rear end to hang freely. When the first and second inclined members 111, 121 move the paper 900 away from the third negative pressure chamber 153, the paper 900 falls onto the conveying mechanism 300 under its own gravity.

[0069] In the fifth step, the conveying mechanism 300 receives the paper 900 at the second workstation and drives the paper 900 to move to the next process.
