    Detailed Description of the Preferred Embodiments
  • As shown in Figures 1 and 2, the high-speed negative suction roller-type oblique feeding folding machine comprises a frame 1, a stacking platform 2, a folding mechanism 4 and a paper feeding mechanism 3. The stacking platform 2 is used for placing a paper stack, that is, package inserts; the folding mechanism 4 is used for folding the paper, which may be folded once or more times; the paper feeding mechanism 3 is used for feeding the paper stack on the stacking platform 2 to the folding mechanism 4 one piece by one piece from the bottom, and finally the folding operation is completed by the folding mechanism 4.
  • The paper feeding mechanism 3 of a general horizontal feeding folding machine comprises a negative suction roller 32 and a paper feeding pressure roller 31 that rotate in a coupled manner for feeding paper, a negative suction hole 320 connected to the vacuum source is arranged on the roller surface of the negative suction roller 32; in order to realize paper feeding, the negative suction roller 32 and the paper feeding pressure roller 31 of the horizontal feeding folding machine are mounted on the sliding block, and paper feeding is realized through the movement of the sliding block and the coupled rotation of the negative suction roller 32 and the paper feeding pressure roller 31.
  • As shown in Figure 1, the stacking platform 2 of this invention is disposed obliquely. As the stacking platform 2 is disposed obliquely, paper feeding cannot be realized by the movement of the sliding block; in order to couple with the obliquely disposed stacking platform 2, the negative suction roller of this invention is drivingly connected with a paper suction transmission mechanism that drives the negative suction roller 32 to rotate back and forth along the curved surface on the paper feeding pressure roller 31. As shown in Figure 5, as the negative suction roller 32 rotates back and forth along the curved surface on the paper feeding pressure roller 31, its movement trajectory is also an oblique line from the start point to the end point, which corresponds to the oblique direction of the stacking platform 2. As shown in Figures 5 and 6, when the negative suction roller 32 sucks the leading edge of the paper through its negative suction hole 320, the paper suction transmission mechanism drives the negative suction roller 32 to move on the paper feeding pressure roller 31 in the direction of the lower left corner (the direction in Figure 6) along the curved surface of the paper feeding pressure roller 31, that is, The arc of the wheel 31, that is, it rotates in the oblique direction of the stacking platform 2, so that the paper is smoothly wound around the negative suction roller 32; in other words, the negative suction roller 32 travels along the paper while rotating, so that the paper is naturally wound on the negative suction drum 32 instead of pulling the paper by force; in this way, the front side of the paper is mostly wound around the negative suction roller 32; as the portion of the paper pressed by the paper stack above is reduced, and the paper enters between the negative suction roller 32 and the paper feeding pressure roller 31, the paper pressure bearing 322 on the negative suction roller 32 and the paper feeding pressure roller 31 grip the paper to take it out and convey it down (the negative suction hole 320 on the negative suction roller 32 is responsible for sucking the paper, and the paper pressure bearing 322 is used to press the paper against the paper feeding pressure roller 31; as the paper pressure bearing 322 is rotatable, the paper pressure bearing 322 and the paper feeding pressure roller 31 press the paper without causing resistance to the paper when the negative suction roller 32 rotates back and forth); when the paper is conveyed down, the paper suction transmission mechanism drives the negative suction roller 32 to move on the paper feeding pressure roller 31 in the direction of the upper right corner (direction in Figure 5) along the curved surface of the paper feeding pressure roller 31 and take another piece of paper.
  • The negative suction roller 32 has a negative suction hole 320. Each time a piece of paper is fed, the negative suction hole 320 sucks once. If the negative suction roller 32 rotates in only one direction, the negative suction roller 32 needs to rotate once to complete the feeding of one piece of paper, which not only affects the paper feeding efficiency, but also makes it difficult to ensure the continuity and accuracy of paper feeding. Therefore, a curved rack 35 is fixedly mounted on the frame 1 according to this invention, a negative suction roller pinion 320 is mounted at one end of the negative suction roller 32, and the negative suction roller pinion 320 engages with the curved rack 35; with the reaction force of the curved rack 35, the negative suction roller 32 can achieve clockwise rotation and counterclockwise rotation when moving back and forth. The advantage of this rotation mode is as follows: as shown in Figure 6, the negative suction roller 32 moves towards the lower left corner (the direction of the stacking platform 2), the negative suction roller 32 rotates only by 180° clockwise to couple with the counterclockwise rotation of the paper feeding pressure roller 31, then the paper is conveyed down, and in this process, the negative suction hole 320 on the negative suction roller 32 only rotates by 180° while sucking the paper; after the paper feeding is completed, the negative suction roller 32 moves towards the upper right corner, and then with the reaction force of the curved rack 35, the negative suction roller 32 rotates by 180° counterclockwise, so that the negative suction hole 320 on the negative suction roller 32 returns to the bottom of the paper stack to suck the next piece of paper; driven by the power source, the paper feeding pressure roller 31 rotates in only one direction, that is, the counterclockwise direction as shown in Figure 6. With the above method, to feed one piece of paper, the negative suction roller 32 only needs to rotate by 180° back and forth, thus significantly increasing the paper feeding speed, and ensuring the continuity and accuracy of the entire paper folding process; meanwhile, the transmission relationship is also simpler, and the structure is also more reasonable.
  • The diameter of the paper feeding pressure roller 31 of this invention is larger than that of the negative suction roller 32, the paper feeding pressure roller 31 with a larger diameter can realize different speed ratios, and is more suitable for feeding different sizes of paper, and at the same time, it can make the movement trajectory of the negative suction roller 32 on its surface closer to the tangent, so that the paper can be more easily wound around the negative suction roller 32; in addition, the inner end of the stacking platform 2 is located above the negative suction roller 32, the negative suction roller 32 is located between the inner end of the stacking platform 2 and the negative suction roller 32, and the negative suction roller 32 rotates back and forth along the oblique direction of the stacking platform 2 on the paper feeding pressure roller 31.
  • The movement of the negative suction roller 32 on the paper feeding pressure roller 31 is driven by the paper suction transmission mechanism, as shown in Figures 1-3. The paper suction transmission mechanism comprises a transmission shaft 33, a transmission pulley 330 and a transmission swing arm 34, the transmission pulley 330 is mounted on the transmission shaft 33, one end of the transmission swing arm 34 is hinged at an eccentric position on the transmission pulley 330, and the other end of the transmission swing arm is hinged on the negative suction roller 32. During operation, the power source drives the transmission shaft 33 to rotate, and the transmission pulley 330 mounted on the transmission shaft 33 rotates accordingly; one end of the transmission swing arm 34 is hinged at an eccentric position on the transmission pulley 330, and the other end of it is hinged on the negative suction roller 32, so the transmission swing arm 34 drives the negative suction roller 32 to move on the paper feeding pressure roller 31 along the curved surface of the paper feeding pressure roller 31.
  • As only one end of the negative suction roller is pressed by the curved rack 35, if the other end is not pressed, the negative suction roller 32 may be lifted when rotating back and forth (if pressed by the left and right two curved racks 35, it is difficult to ensure the consistency of the curved racks 35 on both sides); to this end, the other end of the negative suction roller 32 is mounted with a positioning bearing, the frame 1 is mounted with a positioning curved bar 36, as shown in Figure 1, the positioning bearing acts on the inner curved surface of the positioning curved bar 36. With this structure, it is possible to effectively prevent the negative suction roller 32 from being lifted when moving back and forth, and to ensure the stability of the movement of the negative suction roller 32.
  • In the case where the paper stack is high, the paper may not be taken out by the movement of the negative suction roller 32. In order to ensure that the paper feeding mechanism 3 can work normally, this invention further provides a separation push plate 37, the separation push plate 37 is drivingly connected with the negative suction roller 32 through a connecting arm, the separation push plate 37 is connected with a guiding sheet 371, the guiding sheet 371 is slidably disposed between the two pressing blocks 372, the separation push plate 37 and the stacking platform 2 keep tilted in the same direction, the separation push plate 37 is provided with a blowing hole 370 connected to the air source, and the blowing port of the blowing hole 370 faces the upper portion or the position above the upper portion of the negative suction roller 32. The separation push plate 37 is slidably disposed between the two pressing blocks 372 through the guiding sheet 371, the negative suction roller 32 moves along the curved trajectory, and the separation push plate 37 also moves along with the negative suction roller 32 (the trajectory of the separation push plate 37 is also an arc, so the guiding sheet 371 is resilient); when the negative suction roller 32 sucks the paper, the blowing hole 370 blows toward the upper portion or the position above the upper portion of the negative suction roller 32, the air blown from the blowing hole 370 separates the paper sucked by the negative suction roller 32 from the upper paper and in this way, it is further ensured that the paper can be smoothly taken out.
  • As the front edge of the paper may warp, the negative suction roller 32 can not suck the whole leading edge of the paper. In order to solve this problem, a front baffle plate 38 is disposed above the separation push plate 37 according to this invention, the front baffle plate 38 keeps perpendicular to the stacking platform 2, the front baffle plate 38 is provided with an air jet hole 380 connected to the air source, the air jet port of the air jet hole 380 faces the upper portion of the negative suction roller 32. The front baffle plate 38 can be used to position the front side of the paper stack, and the air jet hole on it can blow the front edge of the paper down after being connected to the air source, so that the front edge of the paper can be completely attached to the negative suction roller 32.
  • As shown in Figure 3, the transmission shaft of this invention is provided with an eccentric weight 311, and the center of gravity of the eccentric weight 311 and the eccentric connection point of the transmission pulley 330 are respectively located on both sides centered on the axis of the transmission shaft. The eccentric weight 331 is used to compensate the transmission shaft 33 for driving the negative suction roller 32 to perform eccentric motion, so that the folding machine can fold the paper smoothly and smoothly at the folding rate of 500 pieces/min.
  • As shown in Figure 4, in order to achieve different speed ratios to realize the fastest folding of different sizes of paper, a drive shaft 65 and a driven shaft 66 are mounted on the frame 1 of this invention, the driven shaft 65 is drivingly connected with the negative suction roller 32 and the paper feeding pressure roller 31, the left drive synchronizing pulley 60 and the right drive synchronizing pulley 62 are disposed on the drive shaft 65, the left driven synchronizing pulley 61 and the right driven synchronizing pulley 63 are disposed on the driven shaft 66, the left drive synchronizing pulley 60 is connected to the left driven synchronizing pulley 61 through the first synchronizing belt, and the right drive synchronizing pulley 62 is connected to the right driven synchronizing pulley 63 through the second synchronizing belt. Every two combination speed ratios can be set on the drive shaft and the driven shaft at the same time, and the change of the paper format area can be completed by simply toggling the shifting device 64, so the combinations are rich, the switching is simple, and the application is wide.
  • As shown in Figure 3, a control shaft 5 is mounted on the frame 1, and the control shaft 5 is mounted with a mechanical valve pneumatic control mechanism 50 and a solenoid valve pneumatic control mechanism 51 capable of controlling the air jet hole 37, blowing hole 38 and negative suction hole 320. The requirements for the linking of the folding machine and the boxing machine are relatively low, and package inserts can be linked with the paper gripping device of the boxing machine only through aeration. The solenoid valve is usually controlled by the photoelectric switch of the boxing machine and the cam controller, and the folding machine can achieve paper folding by programming the PLC and entering the corresponding parameters in the man-machine interface.
  • Finally, it is worth mentioning that in order to prevent the obliquely placed paper stack from sliding down, as shown in Figure 1, the stacking platform 2 of this invention is also provided with a left clamping bar 20 and a right clamping bar 21 for retaining the paper stack, and the position of the left clamping bar 20 and the right clamping bar 21 on the stacking platform can be adjusted to accommodate different sizes of paper.
