[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting a material-dividing plate, two material-dividing plates are initially set, and the two material-dividing plates are set above the edge of the sulfur-free paper, and the distance between the end of the material-dividing plate and the edge of the sulfur-free paper is two centimeters. The two material-dividing plates are initially inclined, and the inclination angle is twenty degrees. When the sulfur-free paper moves upward after being adsorbed by the suction cup, the sulfur-free paper contacts the two inclined material-dividing plates, so that the edge of the sulfur-free paper can be bent. If the bottom of the sulfur-free paper is adhered to the lower layer, the edge tension generated by the bending will concentrate on pulling the adhesion point, and the brittle tearing micro-adhesion or electrostatic adsorption of the paper fiber is used to assist the adhesion of the sulfur-free paper to be peeled off, so as to ensure the stability of subsequent packaging, thereby improving the overall practicality of the device; 2. By arranging the cooperation of parts such as the air intake pipe, the air intake pipe can be rotatably connected with the output end of the external air pump, the air pump can be installed on the outer wall of the baffle, and the gas can be transported into the air intake pipe through the external air pump. The gas can enter the inside of the material-diverting plate through the air intake pipe and be discharged to the outside through multiple inclined grooves. When the sulfur-free paper moves upward and contacts the bottom of the rotating plate, the gas can be blown into the bottom of the sulfur-free paper through multiple inclined grooves for blowing out gas obliquely. If the bottom of the sulfur-free paper is adhered, the adhered sulfur-free paper can be peeled off by the obliquely blown gas in conjunction with the sulfur-free paper bent at the edge, thereby improving the overall effect of peeling off the adhered sulfur-free paper of the device; 3. By setting the cooperation of the driving motor and other parts, when the sulfur-free paper is transferred away and the next sulfur-free paper needs to be adsorbed, the driving motor can be started, and the output end of the driving motor drives the material stripping plate to rotate in the direction of the sulfur-free paper, thereby driving the brush rod to rotate, and the bristles at the ends of the two brush rods can contact the sulfur-free paper, so that the sulfur-free paper can be smoothed. In the previous process, the edge of the sulfur-free paper is bent by the material stripping plate, and the edge will rebound to form wrinkles after leaving the suction cup. The brush rod is smoothed in the opposite direction of the bending to avoid creases again when stacking, thereby ensuring the accuracy of subsequent adsorption of the subsequent sulfur-free paper; 4. By setting up the coordination of parts such as the brush rod, the bristles at the end of the brush rod are against the top of the sulfur-free paper and the bristles are pressed against the top of the sulfur-free paper. At this time, the second spherical rod contacts the lowest point of the inner arc-shaped inclined surface of the arc block. Under the rotation of the material-dispensing plate, it can move along the lowest point of the inner arc-shaped inclined surface of the arc block to the highest point, thereby pushing the second spherical rod to drive the spur rack to move horizontally, and then driving the second spherical rod to drive the one-way threaded screw to rotate, thereby driving the U-shaped block to drive the brush rod to shrink toward the direction of the material-dispensing plate. The shrinking action makes the bristles slide along the top of the sulfur-free paper instead of vertical friction and pulling, thereby reducing the hard wear of the bristles and the sulfur-free paper; 5. By setting the cooperation of parts such as the blowing groove, when the material-dipping plate rotates toward the direction of the sulfur-free paper, when the first spur gear contacts the arc-shaped rack, the first spur gear is driven to drive the rotating plate to rotate away from the material-dipping plate through the connecting shaft. When the material-dipping plate stops rotating, the blowing groove opened on the inner side of the rotating plate is aligned between the two sulfur-free papers. When the rotating plate rotates out from the inner side of the material-dipping plate, the first spherical rod moves from the highest point to the lowest point of the inclined block, so that the extrusion force on the connecting spring is gradually reduced, so that the connecting spring can push the first spherical rod to drive the sealing plate to reset, so that the through groove opened on the inner side of the sealing plate is misaligned with the straight groove, so that the gas inside the air inlet groove can be blown into between the two sulfur-free papers through the blowing groove, and the electrostatic adsorption or tiny friction between the two sulfur-free papers is forcibly cut off by the air pressure difference, thereby solving the problem that traditional suction cups are prone to carry too much sulfur-free paper.

The following is an explanation of an embodiment of the present invention based on the overall structure of the present invention.

[0017] See also Figure 1 to Figure 14The present embodiment provides an automatic board and paper placing machine for product packaging, comprising: a support frame 1 and a conveyor 2, a material tray frame 3 and a linear module 4 respectively installed on the inner side of the support frame 1, a plurality of sulfur-free papers 8 are stacked on the top of the material tray frame 3, a baffle 7 is fixedly connected to the four sides of the sulfur-free paper 8 on the top of the material tray frame 3, and an auxiliary stripper, a smoothing component and an air blowing component are arranged between every two baffles 7; a moving frame 6 is installed on the top of the linear module 4, and a suction cup 5 is installed on the bottom of the moving frame 6, and the auxiliary stripper includes a material stripping plate 9 arranged between the two baffles 7, a driving motor 26 is installed on one side of one baffle 7, and the conveyor 26 of the driving motor 26 is driven by the driving motor 26. The outlet end penetrates to the inner side of the baffle plate 7 and is fixedly connected to the material-diverting plate 9. The blowing assembly includes a rotating plate 13 arranged at the bottom of the material-diverting plate 9. A plurality of inclined grooves 14 communicating with the outside are provided on the inner side of the rotating plate 13. A plurality of straight grooves 15 are provided on the inner side of the rotating plate 13, and each straight groove 15 is communicated with one rotating plate 13. A first corrugated pipe 17 is installed at the air inlet of the top of the rotating plate 13 and the air outlet of the material-diverting plate 9. An air inlet groove 12 communicating with the air outlet is provided inside the material-diverting plate 9. An air inlet pipe 10 communicating with the air inlet groove 12 is fixedly connected to one end of the material-diverting plate 9, and one end of the air inlet pipe 10 penetrates to the outside of the baffle plate 7 and is rotatably connected to the baffle plate 7. First, when the conveyor 2 can be arranged in multiple groups horizontally according to the needs, different plates can be transported respectively. The top of the tray rack 3 is located at the bottom of the sulfur-free paper 8, and a tray and a longitudinal linear module can be arranged. The tray is driven by the longitudinal linear module to drive the top stacked sulfur-free paper 8 to move upward intermittently. A hydraulic cylinder for driving the suction cup 5 to move upward can be installed on the inner side of the movable rack 6. After the sulfur-free paper 8 is adsorbed by the suction cup 5, the adsorbed sulfur-free paper 8 can be driven upward by the hydraulic cylinder, and then it can be transported and transferred by the linear module 4. Since the above operation is a prior art, this scheme does not go into too much detail, and the specific structural composition of the linear module and how the linear module is driven are not described too much in this scheme. This scheme is mainly to solve the problem that the bottom of the sulfur-free paper 8 in the prior art is easily adhered to other sulfur-free papers 8 after being adsorbed by the suction cup. The specific implementation is as follows: Two stripping plates 9 are initially provided, and the two stripping plates 9 are arranged above the edge of the sulfur-free paper 8, and the distance from the end of the stripping plate 9 to the edge of the sulfur-free paper 8 is two centimeters, so that the corners of the sulfur-free paper 8 will not bend significantly. The two stripping plates 9 are initially in an inclined state, and the inclination angle is twenty degrees, so that the sulfur-free paper 8 can be in contact with the inclined stripping plates 9, so that the edges of the sulfur-free paper 8 can be bent in an arc shape, so that the two sulfur-free papers 8 adhered together can be better peeled off later. When the sulfur-free paper 8 is absorbed by the suction cup 5 and moves upward, the sulfur-free paper 8 contacts the two inclined stripping plates 9, so that the edges of the sulfur-free paper 8 can be bent. If the bottom of the sulfur-free paper is adhered to the lower layer, the edge tension generated by the bending will concentrate on pulling the adhesion point, and the brittle tearing micro-adhesion or electrostatic adsorption of the paper fiber is used to assist the adhesion of the sulfur-free paper 8 to be peeled off, thereby ensuring the stability of the subsequent packaging, thereby improving the overall practicality of the device; The air inlet pipe 10 can be rotatably connected to the output end of an external air pump, and the air pump can be installed on the outer wall of the baffle 7. The external air pump can transport gas into the air inlet pipe 10, and the gas can enter the inside of the material-selecting plate 9 through the air inlet pipe 10, and be discharged to the outside through a plurality of inclined grooves 14. When the sulfur-free paper 8 moves upward and contacts the bottom of the rotating plate 13, the gas can be blown into the bottom of the sulfur-free paper 8 through a plurality of inclined grooves 14 for blowing out gas obliquely. If the bottom of the sulfur-free paper 8 is adhered, the adhered sulfur-free paper 8 can be peeled off by the obliquely blown gas in conjunction with the sulfur-free paper 8 bent at the edge, thereby improving the overall peeling effect of the device on the adhered sulfur-free paper 8. The smoothing component includes a brush rod 11 arranged at one end of the material stripping plate 9, the inner side of the material stripping plate 9 is rotatably connected to a one-way threaded screw 34, the outer wall of the one-way threaded screw 34 is threadedly connected to a U-shaped block 33, the inner side of the material stripping plate 9 is provided with a limiting groove 37 matching the U-shaped block 33, and the U-shaped block 33 is slidably connected to the inner side of the limiting groove 37, one end of the U-shaped block 33 extends to the outside of the material stripping plate 9 and is fixedly connected to the brush rod 11, and the smoothing component also includes a fixed connection to the outer wall of the one-way threaded screw 34. A second spur gear 35 of the wall, a spur rack 36 is meshed on the top of the second spur gear 35, one end of the spur rack 36 is fixedly connected to the second spherical rod 25, and one end of the second spherical rod 25 passes through the outside of the material-diverting plate 9 and is slidably connected to the material-diverting plate 9, an auxiliary spring 38 is installed between the spur rack 36 and the material-diverting plate 9, an L-shaped rod 31 is fixedly connected to one side of the baffle 7, one end of the L-shaped rod 31 is fixedly connected to the arc block 27, and the arc block 27 is arranged on the rotation path of the second spherical rod 25; When the sulfur-free paper 8 is transferred away and the next sulfur-free paper 8 needs to be adsorbed, the driving motor 26 can be started, and the output end of the driving motor 26 drives the material stripping plate 9 to rotate in the direction of the sulfur-free paper 8, thereby driving the brush rod 11 to rotate, and the bristles at the ends of the two brush rods 11 can contact the sulfur-free paper 8, so that the sulfur-free paper 8 can be smoothed. In the previous process, the edge of the sulfur-free paper 8 is bent by the material stripping plate 9 (20° inclination angle), and the edge will rebound to form wrinkles after leaving the suction cup 5. The brush rod 11 smoothes it in the opposite direction of the bending to avoid creases again when stacking, thereby ensuring the accuracy of subsequent adsorption of the subsequent sulfur-free paper 8; An arc-shaped inclined surface is provided on one side of the arc block 27. When the material-discharging plate 9 rotates toward the direction of the sulfur-free paper 8, the bristles at the end of the brush rod 11 are against the top of the sulfur-free paper 8 and the bristles are pressed against the top of the sulfur-free paper 8. At this time, the second spherical rod 25 contacts the lowest point of the inner arc-shaped inclined surface of the arc block 27. With the rotation of the material-discharging plate 9, it can move toward the highest point along the lowest point of the inner arc-shaped inclined surface of the arc block 27, thereby pushing the second spherical rod 25 to drive the spur rack 36 to move laterally, and then driving the second spherical rod 25 to drive the one-way threaded screw 34 to rotate, thereby driving the U-shaped block 33 to drive the brush rod 11 to retract toward the direction of the material-discharging plate 9. The retraction action causes the bristles to slide along the top of the sulfur-free paper 8 instead of vertical friction and pulling, thereby reducing the hard wear of the bristles and the sulfur-free paper 8.

[0018] See also Figures 5 to 14A channel switching unit is provided on the inner side of the rotating plate 13, and the channel switching unit includes a blowing groove 18 opened on the inner side of the rotating plate 13, and one end of the blowing groove 18 penetrates to the outside of the rotating plate 13, and the inner side of the material stripping plate 9 is located at the end of the blowing groove 18 and is fixedly connected with an arched sealing rubber 19, and a second bellows 24 is installed at the air inlet of the blowing groove 18 and the air outlet of the air inlet groove 12. The channel switching unit also includes a sealing plate 16 slidably connected to the inner side of the rotating plate 13, and a plurality of through grooves penetrating from the bottom to the top are opened on the inner side of the sealing plate 16, and the through grooves are communicated with the straight grooves 15, and one end of the sealing plate 16 is fixedly connected to a first spherical rod 21, and one end of the first spherical rod 21 penetrates to the outside of the rotating plate 13 and is slidably connected to the rotating plate 13, and the outer wall of the first spherical rod 21 is fixedly connected to a first fixing ring 22, and the first fixing ring 22 is fixedly connected to the outer wall of the first spherical rod 21. A connecting spring 23 is installed between the ring 22 and the rotating plate 13, an inclined block 20 is fixedly connected to one end of the first spherical rod 21 on the inner side of the material-diverting plate 9, and the blowing assembly also includes a fixed seat 41 fixedly connected to the bottom of the material-diverting plate 9, a connecting shaft 30 is fixedly connected to one side of the rotating plate 13, and one end of the connecting shaft 30 passes through the outside of the fixing seat 41 and is rotatably connected to the fixing seat 41, a second circular ring 39 is fixedly connected to the outer wall of the connecting shaft 30, and a torsion spring 40 is installed between the second circular ring 39 and the fixing seat 41, a smooth groove 32 is opened on one side of the baffle 7 and passes through the other side, and one end of the connecting shaft 30 extends from the inside of the smooth groove 32 to the outside and is fixedly connected to the first spur gear 29, and one side of the baffle 7 is located on the rotation path of the first spur gear 29 and is fixedly connected to an arc rack 28, and the arc rack 28 is meshed with the first spur gear 29; When the material-dipping plate 9 rotates toward the sulfur-free paper 8, when the first spur gear 29 contacts the arc-shaped rack 28, the first spur gear 29 is driven to drive the rotating plate 13 to rotate away from the material-dipping plate 9 through the connecting shaft 30. When the material-dipping plate 9 stops rotating, the blowing groove 18 provided on the inner side of the rotating plate 13 is aligned between the two sulfur-free papers 8. When the rotating plate 13 rotates out from the inner side of the material-dipping plate 9, the first spherical rod 21 moves from the highest point of the inclined block 20 to the lowest point, so that the extrusion force on the connecting spring 23 is gradually reduced, so that the connecting spring 23 can push the first spherical rod 21 to drive the sealing plate 16 to reset, so that the through groove provided on the inner side of the sealing plate 16 is misaligned with the straight groove 15, so that the gas inside the air inlet groove 12 can be blown into between the two sulfur-free papers 8 through the blowing groove 18, and the electrostatic adsorption or small friction between the two sulfur-free papers is forcibly cut off by the air pressure difference, thereby solving the problem that the traditional suction cup 5 is easy to carry more sulfur-free papers. After the suction cup 5 absorbs the sulfur-free paper 8, before it needs to be lifted, the driving motor 26 first drives the material-diverting plate 9 to reset, so that the material-diverting plate 9 is tilted upward, and the blowing operation is stopped during the rotation of the material-diverting plate 9; The above steps are reversed so that the rotating plate 13 is stored inside the material stripping plate 9 during the upward tilting of the material stripping plate 9 , and the air outlet of the blowing groove 18 is sealed by the arched sealing rubber 19 , so that the gas can be discharged through the inclined groove 14 .
