An L-shaped rod is fixedly connected to one side of the baffle, and an arc-shaped block is fixedly connected to one end of the L-shaped rod, and the arc-shaped block is arranged on the rotation path of the second spherical rod.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] 1. By providing the material pushing plates, initially two material pushing plates are provided, and the two material pushing plates are arranged above the edge of the sulfur-free paper. The distance from the end of the material pushing plate to the edge of the sulfur-free paper is two centimeters. The two material pushing plates are initially in an inclined state with an inclination angle of twenty degrees. When the sulfur-free paper is adsorbed by the suction cup and moves upward, the sulfur-free paper contacts the two inclined material pushing plates, so that the edge of the sulfur-free paper can be bent. If the bottom of the sulfur-free paper adheres to the lower layer, the edge tension generated by the bending will concentrate on pulling the adhesion point, and the brittle nature of the paper fibers is used to tear the tiny adhesions or electrostatic adsorption, thereby assisting in the peeling of the adhered sulfur-free paper, ensuring the stability of subsequent packaging, and thus improving the overall practicality of the device;

[0014] 2. Through the cooperation of components such as the air inlet pipe, the air inlet pipe can be rotatably connected to the output end of an external air pump. The air pump can be installed on the outer wall of the baffle. Through the external air pump, gas can be transported into the air inlet pipe. The gas can enter the material pushing plate through the air inlet 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, through the multiple inclined grooves that blow out gas obliquely, the gas can be blown into the bottom of the sulfur-free paper. If the bottom of the sulfur-free paper adheres, through the obliquely blown gas and the sulfur-free paper with a bent edge at the edge, the adhered sulfur-free paper can be peeled, thereby improving the overall effect of peeling the adhered sulfur-free paper of the device;

[0015] 3. Through the cooperation of components such as the driving motor, when the sulfur-free paper is transferred away and the next sulfur-free paper needs to be adsorbed and processed, the driving motor can be started. The output end of the driving motor drives the material pushing plate to rotate towards the sulfur-free paper, thereby driving the brush rod to rotate. Through the bristles at the ends of the two brush rods, contact with the sulfur-free paper can be made, and a flattening operation on the sulfur-free paper can be formed. In the previous process, the edge of the sulfur-free paper is bent by the material pushing plate, and after leaving the suction cup, the edge will rebound to form wrinkles. The brush rod flattens along the opposite direction of the bending, avoiding the generation of creases again during stacking, and thus ensuring the accuracy of subsequent adsorption of the sulfur-free paper;

[0016] 4. Through the cooperation of components such as the brush rod, the bristles at the end of the brush rod are pressed against the top of the sulfur-free paper and the bristles are pressed on 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-shaped block. Under the rotation of the material pushing plate, it can move from the lowest point of the inner arc-shaped inclined surface of the arc-shaped block to the highest point, thereby pushing the second spherical rod to drive the straight rack to move horizontally, and further driving the second spherical rod to drive the single-threaded screw rod to rotate, thereby driving the U-shaped block to drive the brush rod to contract towards the material pushing plate. The contraction action makes the bristles slide along the top of the sulfur-free paper instead of vertically rubbing and pulling, reducing the hard wear between the bristles and the sulfur-free paper;

[0017] 5. By setting the cooperation of parts such as the air blowing groove, when the material pushing plate rotates towards the sulfur-free paper, when the first straight gear contacts the arc-shaped rack, the first straight gear is driven to drive the rotating plate to rotate away from the material pushing plate through the coupling shaft. When the material pushing plate stops rotating, the air 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 pushing 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 gradually decreases, 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 the space between the two sulfur-free papers through the air blowing groove, and the electrostatic adsorption or tiny friction between the two sulfur-free papers is forcibly cut off by using the air pressure difference, solving the problem that the traditional suction cup is easy to pick up multiple sulfur-free papers.

The embodiments of the present invention will be described below according to its overall structure.

[0035] Please refer to Figures 1 to 14 , this embodiment provides an automatic plate and paper placing machine for product packaging, including: a support frame 1, a conveyor 2, a tray rack 3, and a linear module 4 respectively installed inside the support frame 1. A plurality of sulfur-free papers 8 are stacked on the top of the tray rack 3. A baffle 7 is fixedly connected to the top of the tray rack 3 around the sulfur-free papers 8. An auxiliary stripper, a flattening component, and a 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 at the bottom of the moving frame 6. The auxiliary stripper includes a material pushing plate 9 arranged between two baffles 7. A driving motor 26 is installed on one side of one of the baffles 7, and the output end of the driving motor 26 penetrates to the inside of the baffle 7 and is fixedly connected to the material pushing plate 9. The blowing component includes a rotating plate 13 arranged at the bottom of the material pushing plate 9. A plurality of inclined slots 14 communicating with the outside are opened on the inner side of the rotating plate 13. A plurality of straight slots 15 are opened on the inner side of the rotating plate 13, and each straight slot 15 communicates 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 pushing plate 9. An air inlet groove 12 communicating with the air outlet is opened inside the material pushing plate 9. One end of the material pushing plate 9 is fixedly connected to an air inlet pipe 10 communicating with the air inlet groove 12, and one end of the air inlet pipe 10 penetrates to the outside of the baffle 7 and is rotatably connected to the baffle 7;

[0036] First, when multiple groups of conveyors 2 can be horizontally arranged according to requirements to convey different boards respectively, a tray and a longitudinal linear module can be provided at the top of the tray rack 3, which is located at the bottom of the sulfur-free paper 8. The longitudinal linear module drives the tray to drive the stacked sulfur-free paper 8 on the top to move upward intermittently. A hydraulic cylinder for driving the suction cup 5 to move upward can be installed inside the moving frame 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 can be conveyed and transferred through the linear module 4. Since the above operations are prior arts, they are not elaborated in this solution. Also, the specific structural composition of the linear module and how the linear module realizes driving are not elaborated in this solution. This solution mainly aims to solve the problem that the bottom of the sulfur-free paper 8 is prone to sticking to other sulfur-free papers 8 in the prior art. The specific implementation is as follows:

[0037] There are initially two material separating plates 9, and the two material separating plates 9 are arranged above the edge of the sulfur-free paper 8. The distance from the end of the material separating 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 be bent significantly. The two material separating plates 9 are initially in an inclined state, and the inclination angle is twenty degrees, which can make the sulfur-free paper 8 contact with the inclined material separating plate 9, so that the edge of the sulfur-free paper 8 can be bent in an arc shape, facilitating the subsequent better peeling of two adhered sulfur-free papers 8. When the sulfur-free paper 8 is adsorbed by the suction cup 5 and moves upward, the sulfur-free paper 8 contacts the two inclined material separating plates 9, so that the edge of the sulfur-free paper 8 can be bent. If the bottom of the sulfur-free paper adheres to the lower layer, the edge tension generated by the bending will concentrate on pulling the adhesion point, using the brittleness of the paper fibers to tear tiny adhesions or electrostatic adsorption, thereby assisting in peeling the adhered sulfur-free paper 8, ensuring the stability of subsequent packaging, and thus improving the overall practicality of the device;

[0038] The air inlet pipe 10 can be rotatably connected to the output end of an external air pump. The air pump can be installed on the outer wall of the baffle 7. The external air pump can convey gas into the air inlet pipe 10. The gas can enter the material separating plate 9 through the air inlet pipe 10 and be discharged to the outside through multiple inclined slots 14. When the sulfur-free paper 8 moves upward and contacts the bottom of the rotating plate 13, through the multiple inclined slots 14 that blow out gas obliquely, the gas can be blown into the bottom of the sulfur-free paper 8. If the bottom of the sulfur-free paper 8 adheres, the gas blown out obliquely and the sulfur-free paper 8 with a bent edge at the edge are used to peel the adhered sulfur-free paper 8, thereby improving the overall effect of peeling the adhered sulfur-free paper 8 of the device;

[0039] The flattening component includes a brush rod 11 arranged at one end of the material pushing plate 9. A unidirectional threaded lead screw 34 is rotatably connected to the inner side of the material pushing plate 9. A U-shaped block 33 is threadedly connected to the outer wall of the unidirectional threaded lead screw 34. A limiting groove 37 matching the U-shaped block 33 is formed in the inner side of the material pushing plate 9, 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 pushing plate 9 and is fixedly connected to the brush rod 11. The flattening component further includes a second straight gear 35 fixedly connected to the outer wall of the unidirectional threaded lead screw 34. A straight rack 36 is meshed with the top of the second straight gear 35. One end of the straight rack 36 is fixedly connected to a second spherical rod 25, and one end of the second spherical rod 25 penetrates to the outside of the material pushing plate 9 and is slidably connected to the material pushing plate 9. An auxiliary spring 38 is installed between the straight rack 36 and the material pushing plate 9. One side of the baffle 7 is fixedly connected to an L-shaped rod 31. One end of the L-shaped rod 31 is fixedly connected to an arc-shaped block 27, and the arc-shaped block 27 is arranged on the rotation path of the second spherical rod 25;

[0040] When the sulfur-free paper 8 is transferred away and the next sulfur-free paper 8 needs to be adsorbed and processed, the driving motor 26 can be started. The output end of the driving motor 26 drives the material pushing plate 9 to rotate towards the sulfur-free paper 8, thereby driving the brush rod 11 to rotate. The bristles at the ends of the two brush rods 11 can contact the sulfur-free paper 8, and a flattening operation on the sulfur-free paper 8 can be formed. In the previous process, the edge of the sulfur-free paper 8 is bent by the material pushing plate 9 (20° inclination angle). After leaving the suction cup 5, the edge will rebound to form wrinkles. The brush rod 11 flattens along the reverse direction of the bend, avoiding the generation of creases again during stacking, and thus ensuring the accuracy of the subsequent adsorption of the sulfur-free paper 8;

[0041] One side of the arc-shaped block 27 is provided with an arc-shaped inclined surface. When the material pushing plate 9 rotates towards the sulfur-free paper 8, after the bristles at the end of the brush rod 11 abut against the top of the sulfur-free paper 8 and press the bristles on 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-shaped block 27. Under the rotation of the material pushing plate 9, it can move from the lowest point to the highest point along the inner arc-shaped inclined surface of the arc-shaped block 27, thereby pushing the second spherical rod 25 to drive the straight rack 36 to move horizontally, and further driving the second spherical rod 25 to drive the unidirectional threaded lead screw 34 to rotate, so as to drive the U-shaped block 33 to drive the brush rod 11 to contract towards the material pushing plate 9. The contraction action enables the bristles to slide along the top of the sulfur-free paper 8 instead of vertically rubbing and pulling, reducing the hard wear between the bristles and the sulfur-free paper 8.

[0042] Please refer to Figures 5 to 14, a channel switching unit is provided inside the rotating plate 13. The channel switching unit includes a blowing groove 18 opened inside the rotating plate 13, and one end of the blowing groove 18 penetrates to the outside of the rotating plate 13. An arched sealing rubber 19 is fixedly connected to the inner side of the feeding plate 9 at the end of the blowing groove 18. A second corrugated pipe 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 further includes a sealing plate 16 slidably connected inside the rotating plate 13. A plurality of through grooves penetrating from the bottom to the top are opened inside the sealing plate 16, and the through grooves communicate with the straight groove 15. 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. A first fixing ring 22 is fixedly connected to the outer wall of the first spherical rod 21, and a connecting spring 23 is installed between the first fixing ring 22 and the rotating plate 13. An inclined block 20 is fixedly connected to the inner side of the feeding plate 9 at one end of the first spherical rod 21. The blowing assembly further includes a fixed seat 41 fixedly connected to the bottom of the feeding plate 9. One side of the rotating plate 13 is fixedly connected to a connecting shaft 30, and one end of the connecting shaft 30 penetrates to the outside of the fixed seat 41 and is rotatably connected to the fixed seat 41. A second ring 39 is fixedly connected to the outer wall of the connecting shaft 30, and a torsion spring 40 is installed between the second ring 39 and the fixed seat 41. A through groove 32 penetrating from one side to the other side is opened on one side of the baffle 7, and one end of the connecting shaft 30 extends from the inside of the through groove 32 to the outside and is fixedly connected to a first straight gear 29. An arc-shaped rack 28 is fixedly connected to one side of the baffle 7 on the rotation path of the first straight gear 29, and the arc-shaped rack 28 is meshed with the first straight gear 29;

[0043] When the feeding plate 9 rotates towards the sulfur-free paper 8, when the first straight gear 29 contacts the arc-shaped rack 28, the first straight gear 29 is driven to drive the rotating plate 13 to rotate away from the feeding plate 9 through the connecting shaft 30. When the feeding plate 9 stops rotating, the blowing groove 18 opened inside the rotating plate 13 is aligned between the two sulfur-free papers 8. When the rotating plate 13 rotates out from the inside of the feeding plate 9, the first spherical rod 21 moves from the highest point to the lowest point of the inclined block 20, so that the extrusion force received by the connecting spring 23 gradually decreases, 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 opened inside 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 the space between the two sulfur-free papers 8 through the blowing groove 18, and the electrostatic adsorption or tiny friction between the two sulfur-free papers is forcibly cut off by using the air pressure difference, solving the problem that the traditional suction cup 5 is easy to lift multiple sulfur-free papers;

[0044] After the suction cup 5 adsorbs the sulfur-free paper 8 and before it needs to be lifted, the driving motor 26 first drives the feeding plate 9 to reset, so that the feeding plate 9 is tilted upward. At the same time, the blowing operation stops during the rotation of the feeding plate 9;

[0045] Reverse the above steps so that during the process of the material pushing plate 9 tilting upward, the rotating plate 13 is received inside the material pushing plate 9, and the air outlet of the air blowing groove 18 is sealed by the arched sealing rubber 19, so that the gas can be discharged through the inclined groove 14.

[0046] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
