Description

Technical Field

[0001] The invention relates to the technical field of paper feeding devices, in particular to a positioning paper feeding device for white cardboard processing. Background Art

[0002] Currently, the common paper feeding device sucks up the jammed paper through a suction cup, and then controls the suction cup to move to send it between two rollers or wheels, and then sends it to the back-end transmission equipment or processing equipment by rotating the two rollers or wheels towards each other. For wider jammed paper, it is generally sucked by multiple suction cups, that is, multiple suction cups are installed on the same structural member (usually an optical axis or an optical rod), and then the movement of the structural member is controlled to drive all suction cups to move synchronously.

[0003] However, in actual use, sometimes the required cardboard size will change due to product changes. At this time, it is necessary to adjust the positions of multiple suction cups to adapt to cardboards of different widths. Otherwise, some suction nozzles will not contact the cardboard, causing vacuum leakage and resulting in poor suction.

The driving assembly is installed on the frame 1, and the bracket 4 can be driven to slide by the driving assembly. The feeding assembly is connected to the loading assembly, and the cardboard sent by the loading assembly can be sent to the back-end processing equipment.

[0031] When in use, just place the white cardboard raw material on the stocking component, then pick up the white cardboard in the stocking component through the loading component and pass it to the feeding component to complete the positioning and paper feeding process, wherein the stocking component can adjust the position of the limit plate 3 through the first adjustment component to be compatible with a variety of white cardboards of different sizes, and when the first adjustment component is in operation, it can also drive the second adjustment component to operate, and then drive the suction nozzle 5 in the loading component to automatically adjust the position, thereby realizing automatic adjustment, so that maintenance personnel do not need to disassemble and assemble the suction nozzle 5 for adjustment, which greatly facilitates use.

[0032] like Figure 1 As shown, the limiting plate 3 includes a transverse plate 301 and a longitudinal plate 302, both of which are slidably arranged on the surface of the support plate 2, and the transverse plate 301 and the longitudinal plate 302 are vertically distributed. There are two transverse plates 301, and they are symmetrically distributed in the middle of the frame 1, so that the white card paper can be limited in length and width directions.

[0033] like Figure 3As shown, the first adjustment component includes a first screw rod 6, a first threaded seat 7 and a first slide groove 8. The first slide groove 8 is opened through the surface of the support plate 2. There are two first threaded seats 7, and both are slidably set in the first slide groove 8. At the same time, the two cross plates 301 are fixedly connected to the two first threaded seats 7 respectively. The first screw rod 6 is rotatably installed under the support plate 2, and the first screw rod 6 and the two first threaded seats 7 are respectively connected by left-handed threads and right-handed threads. In this way, only the first screw rod 6 needs to rotate to drive the two first threaded seats 7 to move closer to each other, which will synchronously drive the two cross plates 301 to move closer to each other until they are in contact with the edge of the white cardboard, thereby realizing the width direction positioning of the white cardboard.

[0034] like Figure 3 and Figure 5 As shown, a baffle 9 is fixedly installed on one side of the horizontal plate 301 away from the vertical plate 302, and the two baffles 9 are located between the two horizontal plates 301. In this way, the white cardboard can be positioned in the length direction by the cooperation between the baffle 9 and the vertical plate 302. The first adjustment component also includes a second screw rod 10, a second threaded seat 11 and a second slide groove 12. The second slide groove 12 is penetrated and opened on the support plate 2. The second threaded seat 11 is slidably installed in the second slide groove 12. The second screw rod 10 is rotatably installed under the support plate 2, and the second screw rod 10 is threadedly connected to the second threaded seat 11. In this way, only the second screw rod 10 needs to rotate to drive the vertical plate 302 to move, so as to push the white cardboard raw material to move toward the baffle 9 until the edge of the white cardboard raw material fits with the baffle 9 and the vertical plate 302, thereby realizing the positioning of the white cardboard in the length direction.

[0035] like Figure 1 , Figure 2 as well as Figure 3 As shown, a first hand wheel 13 is fixedly mounted on the end of the first screw rod 6, and a second hand wheel 14 is fixedly mounted on the end of the second screw rod 10. Thus, the first screw rod 6 can be driven to rotate by rotating the first hand wheel 13, and the second screw rod 10 can be driven to rotate by rotating the second hand wheel 14.

[0036] like Figure 6 and Fig. 9As shown, the bracket 4 is a hollow structure, the second adjustment component includes a first connecting rod 15, a second connecting rod 16, a connecting pipe 17 and a power component, the first connecting rod 15 and the second connecting rod 16 have the same structural size and are both installed in the bracket 4, and at the same time, there are a plurality of first connecting rods 15 and a second connecting rod 16, and the number is the same and the position is relative, the ends of the plurality of first connecting rods 15 are rotated and connected together in sequence, and the ends of the plurality of second connecting rods 16 are rotated and connected together in sequence, and at the same time, the middle of the first connecting rod 15 and the second connecting rod 16 in relative positions are rotated and connected together in a cross shape, and the connecting pipe 17 is rotatably installed between the first connecting rod 15 and the second connecting rod 16. At the rotating connection of the two connecting rods 16, the top end of the connecting tube 17 is connected to the external vacuum, the suction nozzle 5 is installed at the bottom end of the connecting tube 17, and the upper and lower surfaces of the bracket 4 are provided with a third sliding groove 18 that penetrates through. The first sliding seat 19 is slidably installed in the third sliding groove 18, and the connecting tube 17 is rotatably installed in the middle of the first sliding seat 19. The power component is connected to the first connecting rod 15 and the second connecting rod 16 at the same time, and the rotation of the first connecting rod 15 and the second connecting rod 16 is controlled by the power component. At the same time, a transmission component is connected between the power component and the first adjusting component, and the first adjusting component can drive the power component to operate through the transmission component.

[0037] In this way, when the first adjustment component is in operation, the transmission component can drive the power component to operate, and the power component will drive the first connecting rod 15 and the second connecting rod 16 to rotate, thereby driving the connecting tube 17 to move synchronously, and then driving the suction nozzles 5 to move closer to or away from each other, so that the spacing between the suction nozzles 5 automatically corresponds to the size of the white paper card, thereby realizing automatic adjustment, thereby eliminating the need for manual disassembly and adjustment, and greatly facilitating use.

[0038] like Fig. 9 As shown, the power assembly includes a third screw rod 20 and a third threaded seat 21. The third screw rod 20 is a double-headed screw rod. The third screw rod 20 is rotatably installed in the middle of the bracket 4. There are two third threaded seats 21, which are respectively connected to the third screw rod 20 with left-handed threads and right-handed threads. The two third threaded seats 21 are respectively rotatably connected to the ends of the first connecting rod 15 and the second connecting rod 16. At the same time, the positions of the first connecting rod 15 and the second connecting rod 16 rotatably connected to the two third threaded seats 21 correspond to each other, and the rotational connection parts also correspond. At the same time, the first connecting rod 15 and the second connecting rod 16 on both sides of the third screw rod 20 are symmetrically distributed.

[0039] In this way, the two third threaded seats 21 can be driven to synchronously move toward or away from the middle of the third screw rod 20 only by rotating the third screw rod 20. In this process, the first connecting rod 15 and the second connecting rod 16 can be synchronously driven to rotate relative to each other.

[0040] like Figure 1 , Figure 2 and Figure 6As shown, the transmission assembly includes a first gear 22, a rack 23, a guide rail 24, a slider 25, a third connecting rod 26 and a telescopic rod 27. The first gear 22 is rotatably mounted on the side of the bracket 4, and the first gear 22 is coaxially connected to the rotating shaft of the third screw rod 20. The rack 23 is slidably mounted on the side of the bracket 4 and the rack 23 is meshed with the first gear 22. The guide rail 24 is fixedly mounted on the side of the bracket 4. The slider 25 is slidably mounted on the surface of the guide rail 24, and the slider 25 is fixedly connected to the side of the rack 23. One end of the third connecting rod 26 is fixedly connected to the side of the slider 25, and the other end is rotatably connected to the end of the telescopic rod 27. The end of the telescopic rod 27 away from the third connecting rod 26 is rotatably connected to the side of a horizontal plate 301.

[0041] In this way, when the cross plate 301 moves, it will drive the telescopic rod 27 to move synchronously, thereby driving the third connecting rod 26 to move, the third connecting rod 26 will drive the slider 25 to move, and then drive the rack 23 to move synchronously, the rack 23 will drive the first gear 22 to rotate, and the rotation of the first gear 22 will rotate the third screw rod 20.

[0042] like Figure 1 , Figure 3 , Figure 7 and Figure 8 As shown, the driving assembly includes a motor 28, a crankshaft 29, a fourth connecting rod 30, a limit rod 31 and a guide groove 32. The motor 28 is fixedly mounted on the side of the frame 1. The main shaft of the crankshaft 29 is coaxially connected to the output shaft of the motor 28. One end of the fourth connecting rod 30 is rotatably connected to the bent portion of the crankshaft 29. The guide groove 32 is provided on the side of the frame 1. There are two limit rods 31, which are rotatably mounted on the side of the bracket 4. At the same time, the two limit rods 31 are rollingly mounted in the guide groove 32. The end of the fourth connecting rod 30 away from the crankshaft 29 is rotatably connected to a limit rod 31.

[0043] In this way, it is only necessary to start the motor 28, the motor 28 will drive the crankshaft 29 to rotate, and the crankshaft 29 will drive the limit rod 31 to slide in the guide groove 32 through the fourth connecting rod 30, thereby driving the bracket 4 to slide synchronously. During the sliding process of the bracket 4, the suction nozzle 5 will be driven to move synchronously, wherein the suction nozzle 5 will suck up a piece of white cardboard when it is close to the white cardboard raw material.

[0044] It should be noted that there are two groups of limit rods 31 symmetrically distributed on both sides of the bracket 4 , and each group has two limit rods. Both of the two limit rods 31 are in one guide groove 32 , so that the bracket 4 can be kept balanced.

[0045] like Figure 1As shown, the guide groove 32 is inclined, and the lower part is close to the material storage component, and the higher part is close to the material feeding component. There are two crankshafts 29 and two fourth connecting rods 30, which are symmetrically distributed on both sides of the bracket 4. At the same time, the main shafts of the two crankshafts 29 are coaxially connected. In this way, it can be ensured that the suction nozzle 5 can suck up the previous white cardboard after approaching the white cardboard, and feed the material feeding component at the rear end of the paper when the bracket 4 moves to a higher position.

[0046] like Figure 2 , Figure 5 , Figure 7 and Figure 8 As shown, the feeding assembly includes a feeding roller 33 and a second gear 34. There are two feeding rollers 33 and two second gears 34. The two feeding rollers 33 are rotatably installed in the middle of the frame 1. The two second gears 34 are coaxially connected to the rotating shafts of the two feeding rollers 33, and the two second gears 34 are meshed. The feeding roller 33 and the main shaft of the crankshaft 29 are driven by a pulley 35 and a synchronous belt 36. When the feeding assembly is running, the white cardboard can be fed to the middle of the two feeding rollers 33, and the feeding rollers 33 can drive the white cardboard to move when they rotate.

[0047] In this way, during the rotation of the crankshaft 29, the feed roller 33 will also be driven to rotate through the pulley 35 and the synchronous belt 36, and the two feed rollers 33 will rotate towards each other under the action of the second gear 34. In this way, after the white card paper is fed into the two feed rollers 33, the feed rollers 33 will send the white card paper to the rear end, thereby completing the entire positioning paper feeding process.

[0048] Therefore, the complete usage process is to first place the white cardboard raw material on the support plate 2 and make it between the two horizontal plates 301. At the same time, the white cardboard raw material needs to be between the baffle plate 9 and the longitudinal plate 302. At this time, if there is a gap between the two horizontal plates 301 and the edge of the white cardboard raw material, the first hand wheel 13 can be manually turned, and the first hand wheel 13 will drive the first screw rod 6 to rotate, thereby driving the two first threaded seats 7 to move closer to each other, which will synchronously drive the two horizontal plates 301 to move closer to each other until they are in contact with the edge of the white cardboard. At the same time, the second hand wheel 14 can be manually turned to drive the second screw rod 10 to rotate, thereby driving the longitudinal plate 302 to move, so as to push the white cardboard raw material to move toward the baffle plate 9 until the edge of the white cardboard raw material is in contact with the baffle plate 9 and the longitudinal plate 302. In this way, the white cardboard can be completed. The raw material is limited, and then the motor 28 is started. The motor 28 will drive the crankshaft 29 to rotate, and the crankshaft 29 will drive the limiting rod 31 to slide in the guide groove 32 through the fourth connecting rod 30, thereby driving the bracket 4 to slide synchronously. During the sliding process of the bracket 4, the suction nozzle 5 will be driven to move synchronously, wherein the suction nozzle 5 will suck a piece of white cardboard when it is close to the white cardboard raw material, and when the suction nozzle 5 is close to the feeding roller 33, the sucked white cardboard will be sent between the two feeding rollers 33, and during the rotation of the crankshaft 29, the feeding roller 33 will be driven to rotate through the pulley 35 and the synchronous belt 36, and the two feeding rollers 33 will rotate towards each other under the action of the second gear 34, so that after the white cardboard is fed into the two feeding rollers 33, the feeding rollers 33 will send the white cardboard to the rear end, thereby completing the entire positioning and paper feeding process.

[0049] Among them, in the process of adjusting the cross plate 301 to fit the edge of the white cardboard, the movement of the cross plate 301 will drive the slider 25 to slide on the guide rail 24 through the telescopic rod 27 and the third connecting rod 26, thereby driving the rack 23 to slide synchronously, and the rack 23 will drive the first gear 22 to rotate. The rotation of the first gear 22 will rotate the third screw rod 20, thereby driving the two third threaded seats 21 to synchronously move closer to or away from the middle of the third screw rod 20. In this process, the first connecting rod 15 and the second connecting rod 16 will be synchronously driven to rotate relative to each other, thereby driving the connecting tube 17 to move synchronously, and then driving the suction nozzles 5 to move closer to or away from each other, so that the spacing between the suction nozzles 5 automatically corresponds to the size of the white paper card, thereby realizing automatic adjustment, so that there is no need for manual disassembly and adjustment, which greatly facilitates use.

[0050] In addition, during use, since the first connecting rod 15 and the second connecting rod 16 on both sides of the third screw rod 20 are symmetrically distributed, when the first connecting rod 15 and the second connecting rod 16 rotate, they will synchronously drive all the suction nozzles 5 to move synchronously, thereby ensuring that the spacing between each suction nozzle 5 is always the same, thereby ensuring that the suction force of the white cardboard is evenly distributed, and effectively ensuring the stable operation of the equipment.

[0051] In summary, during use, when replacing white cardboard raw materials of different sizes, the position of the limit plate 3 can be adjusted in real time through the first adjustment component to limit it well, and in this process, the spacing between each suction nozzle 5 can be synchronously adjusted through the second adjustment component to correspond to the width of the white cardboard, so that there is no need to disassemble and adjust each suction nozzle 5, which greatly facilitates use.

[0052] In addition, during use, when the first adjustment component drives the second adjustment component to operate, it synchronously drives each suction nozzle 5 to move. In this way, it can ensure that the distance between each suction nozzle 5 is always the same, so that the suction force of the white card paper can be evenly distributed, which will effectively ensure the stability of the equipment operation.

[0053] At the same time, during the operation of the entire device, the position of the first adjustment component and the second adjustment can also be adjusted in real time without stopping the machine for adjustment, which can facilitate real-time observation and timely adjustment of the working position of the suction nozzle 5. It is flexible and versatile to use, convenient for debugging and maintenance, and further facilitates use.

[0054] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
