Description

Technical Field

[0001] The present invention relates to the technical field of laser marking equipment, and specifically to a fully automatic double-sided laser marking machine for carton processing. Background Art

[0002] The intelligent manufacturing equipment industry includes intelligent welding systems, intelligent heat treatment production lines, automatic and semi-automatic arc, plasma arc welding machines and other metal cutting and welding equipment manufacturing. Among them, laser equipment is an important part. A laser marking machine uses a laser beam to make permanent marks on the surfaces of various different substances. The marking principle is to expose the deep layer of substances by evaporating the surface layer of substances, so as to engrave beautiful patterns, trademarks and characters. Currently, the most common carton laser marking machine on the market requires operators to place the cartons to be marked one by one on the conveyor belt. When the cartons reach the position of the marking machine, the marking machine performs the marking operation.

[0003] When the existing laser marking equipment marks a carton, if it is necessary to accurately align the middle position on both sides of the carton body for marking, it is necessary to adjust the position of the laser marking device in advance according to the dimensions such as the length, width and height of the carton. This method needs to be adjusted separately before processing cartons of different sizes each time, which is rather inconvenient. Summary of the Invention

[0004] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide a fully automatic double-sided laser marking machine for carton processing to solve the problems raised in the above background art.

[0009] Furthermore, a plurality of return springs are fixed to the tail end of the top plate, and the other end of the return spring is fixedly connected to the back side of the transfer platform, vertical rods are fixed to the top of the top plate and the cross beam, the tops of the two vertical rods are connected to connecting plates, and the vertical rods at the top of the cross beams are fixedly connected to the connecting plates, a movable groove is opened on the connecting plate corresponding to the top of the transfer platform, and the vertical rods at the top of the transfer platform slide along the inside of the movable groove through a slide plate.

[0010] Further, the marking assembly further includes a laser device. A laser device is provided between the two side plates. Four groups of connecting rods are symmetrically and rotatably connected to the back of the laser device through a rotating shaft. The four groups of connecting rods are respectively rotatably connected to the bottom of the cross beam and the side plates through a rotating shaft.

[0011] Further, the interception assembly further includes a vertical column. Vertical columns are provided at both ends of the marking table corresponding to the transfer table, and a slot is opened at the top of the vertical column.

[0012] Further, the bottom of the vertical column is rotatably installed with a long plate through a bearing, and the bottom of the second baffle is rotatably installed at the other end of the long plate through a rotating shaft. A chute is opened on the surface of the marking table near the bottom of the second baffle, and the long plate slides along the chute.

[0013] Further, a transmission belt is sleeved on the bottom of the vertical column, and the other pulley of the transmission belt is rotatably installed on the surface of the long plate near the bottom of the second baffle through a rotating shaft.

[0014] Further, a first gear is fixed to the bottom of the rotating shaft of the second baffle, and a second gear is fixed to the surface of the other pulley of the transmission belt. The first gear is meshed with the second gear.

[0015] Advantages of the present invention: When the present invention keeps the cardboard box moving along the marking table and the transfer table, it can be limited and will not shift. Moreover, the second limiting plates and the first limiting plates on the transfer table and the marking table are adjusted synchronously. Through the cooperation of the steering motor and the first electric push rod, the inlet ends of the transfer table and the marking table are brought closer, and the cardboard box is conveyed through the roller shafts of the two.

[0016] The present invention pushes the transfer table outwards through the first electric push rod to prevent the transfer table from being interfered by the marking table and unable to rotate. Then, the steering motor drives the transfer table to rotate, and the opening of the transfer table faces outwards to receive the cardboard box sent by the conveying table. Since there are second insertion blocks at both ends of the second limiting plate, after the rotation direction, the second insertion blocks on the back can still be inserted into the jacks of the first limiting plate. The rotation of the screw driven by the motor drives the second limiting plate and the first limiting plate to move synchronously to adjust the thickness of both sides of the cardboard box.

[0017] When the carton enters from the entrance end of the transfer table in the present invention, its top will be squeezed by the inclined plate, so the height of the top plate will be adjusted to keep the top plate in squeezing contact with the top of the carton. At the same time, the connecting plate and the two vertical rods will synchronously adjust their heights, which will also drive the adjustment of the position of the cross beam to keep the height of the cross beam corresponding to that of the carton. After the cross beam is adjusted, through the rotation of the connecting rod, the laser device will approach the middle position of the carton from the vertical direction. The moving groove of the connecting plate can allow the vertical column to slide along the moving groove when the transfer table moves outwards without causing moving interference.

[0018] In the present invention, through the rotation of the vertical column and the transmission of the transmission belt, the first gear meshes with the second gear and rotates to drive the second baffle to rotate and open. At this time, the positions of the inserting block and the inserting slot are perpendicular to the moving direction of the transfer table. Therefore, when the moving frame drives the first baffle to move, the vertical column and the long plate will move together, squeezing the outside of the carton by the first baffle, cooperating with the back surface of the transfer table to measure the width of the carton and locking it in this position. Subsequently, the first baffle is opened by the electric rotating shaft and the second baffle is closed. Because the positions of the first baffle and the second baffle are adjusted synchronously, when the carton moves to the position of the second baffle, the middle positions on both sides will just correspond to the laser device, so as to keep the marking position close to the middle area.

[0019] Compared with the prior art, in the present invention, through the cooperation of the feeding component and the marking table, the dimensions such as the length, width and height of the carton are measured before feeding, and the positions of each limiting structure on the marking component and the marking table are synchronously adjusted to match the size of the carton. The carton can be limited during the moving process. The intercepting component is adjusted according to the width of the carton to keep the marking position of the carton maintained at a position close to the middle of both sides, avoiding the deviation of the marking position.

Specific embodiments

[0022] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0023] Please refer to Figures 1 to 8, the present invention provides a technical solution: a fully automatic double-sided laser marking machine for carton processing, including a marking table 1. A feeding assembly 2 is provided at the front end of the marking table 1. The feeding assembly 2 includes a transfer table 22, and a plurality of roller shafts are evenly rotatably installed on the surfaces of the marking table 1 and the transfer table 22. A first limiting plate 11 is slidably installed on the surface of the marking table 1, and a second limiting plate 29 is slidably installed on the surface of the transfer table 22. A top plate 211 is slidably inserted into the top of the transfer table 22, and an upward inclined plate 213 is fixed at one end of the top plate 211 corresponding to the entrance end of the transfer table 22. A marking assembly 3 is provided at the middle top of the transfer table 22. The marking assembly 3 includes two groups of side plates 31. The two groups of side plates 31 are respectively fixed on one side of the marking table 1 and the top of the first limiting plate 11. A cross beam 32 is provided at the top of the side plate 31, and telescopic rods 34 are symmetrically fixed inside the side plate 31. A moving plate 33 is slidably sleeved on the surface of the cross beam 32 located at the top of the first limiting plate 11. The extending ends of the telescopic rods 34 of the side plate 31 are respectively fixed to one end of the cross beam 32 and the moving plate 33. Intercepting assemblies 4 are provided on both sides of the entrance end of the transfer table 22 and the exit side of the marking assembly 3. The intercepting assembly 4 includes a first blocking plate 28. The first blocking plates 28 are symmetrically provided on both sides of the entrance end of the transfer table 22, and second blocking plates 44 are provided on both sides of the transfer table 22 at the exit end of the marking assembly 3. And the first blocking plate 28 and the second blocking plate 44 are in transmission connection. When using the device, the cartons are intermittently conveyed by a conventional conveying table. The transfer table 22 rotates outwards to receive the cartons. The positions of the top plate 211 and the second limiting plate 29 are adjusted according to the width and height of the cartons. The first limiting plate 11 and the cross beam 32 on the marking table 1 are adjusted synchronously. Then the open end of the transfer table 22 rotates to correspond to the marking table 1. After measuring the length of the carton by the first blocking plate 28 and adjusting the position of the second blocking plate 44, the carton is sent out. The carton moves along the marking table 1, passes through the interception of the second blocking plate 44, and the laser device 36 of the marking assembly 3 performs simultaneous marking work on the middle areas on both sides of the carton. Finally, through the opening of the second blocking plate 44, the carton is sent out and received from the tail end of the marking table 1.

[0024] In this embodiment, the feeding assembly 2 further includes a base 21. The bottom of the transfer table 22 is rotatably mounted on the base 21 through a bearing. Two sets of first electric push rods 13 are fixed at the position of the marking table 1 corresponding to the base 21, and the extending ends of the first electric push rods 13 are fixedly connected to the base 21. A steering motor 23 is fixed to the bottom of the base 21, and the output end of the steering motor 23 is fixedly connected to the transfer table 22. A screw rod 216 is rotatably mounted on the back of the transfer table 22. One end of the second limiting plate 29 is threadedly sleeved on the screw rod 216. Second insertion blocks 210 are fixed at the front and rear ends of one side of the first limiting plate 11 and the transfer table 22. Jacks 12 are provided at the positions of the side of the marking table 1 and the first limiting plate 11 corresponding to the second insertion blocks 210. The second insertion blocks 210 are slidably inserted into the jacks 12. A moving frame 25 is provided on the back of the transfer table 22. Electric rotating shafts 26 are slidably inserted into the transfer table 22 from both sides of the top of the moving frame 25. The first baffle 28 is rotatably mounted on the moving frame 25 through the electric rotating shafts 26. Second electric push rods 24 are fixed to both sides of the bottom of the transfer table 22, and the extending ends of the second electric push rods 24 are fixedly connected to the moving frame 25. The transfer table 22 is pushed outwards by the first electric push rod 13 to prevent the transfer table 22 from being interfered by the marking table 1 and unable to rotate. Then, the steering motor 23 drives the transfer table 22 to rotate, turning the opening of the transfer table 22 outwards to receive the cartons sent out by the conveying table. Since there are second insertion blocks 210 at both ends of the second limiting plate 29, after the rotation direction, the second insertion blocks 210 on the back can still be inserted into the jacks 12 of the first limiting plate 11. The screw rod 216 driven by the motor rotates to drive the second limiting plate 29 and the first limiting plate 11 to move synchronously, adjusting the thickness of both sides of the carton to keep the carton under the limiting effect when moving along the marking table 1 and the transfer table 22, without deviation, and keeping the second limiting plate 29 and the first limiting plate 11 on the transfer table 22 and the marking table 1 adjusted synchronously. Through the cooperation of the steering motor 23 and the first electric push rod 13, the transfer table 22 is brought close to the entrance end of the marking table 1, and the cartons are conveyed by the roller shafts of both of them.

[0025] In this embodiment, a plurality of reset springs 212 are fixed to the tail end of the top plate 211, and the other ends of the reset springs 212 are fixedly connected to the back surface of the transfer table 22. Vertical rods 215 are fixedly installed on the top of both the top plate 211 and the cross beam 32. A connecting plate 214 is connected to the tops of the two vertical rods 215, and the vertical rod 215 on the top of the cross beam 32 is fixedly connected to the connecting plate 214. A moving groove 217 is formed in the connecting plate 214 corresponding to the top of the transfer table 22. The vertical rod 215 on the top of the transfer table 22 slides along the inside of the moving groove 217 through a sliding plate. The marking assembly 3 further includes a laser device 36. The laser device 36 is arranged between the two side plates 31. Four groups of connecting rods 35 are symmetrically rotatably connected to the back surface of the laser device 36 through rotating shafts. The four groups of connecting rods 35 are respectively rotatably connected to the bottom of the cross beam 32 and the side plates 31 through rotating shafts. When the cardboard box enters from the entrance end of the transfer table 22, its top will be squeezed by the inclined plate 213, so that the height of the top plate 211 will be adjusted to keep the top plate 211 in squeezing contact with the top of the cardboard box. At the same time, the connecting plate 214 and the two vertical rods 215 will be adjusted in height synchronously, and the position of the cross beam 32 will also be driven to be adjusted to keep the height of the cross beam 32 corresponding to that of the cardboard box. At the same time, after the cross beam 32 is adjusted, through the rotation of the connecting rods 35, the laser device 36 is moved from the vertical direction to a position close to the middle of the cardboard box. The moving groove 217 of the connecting plate 214 can allow the vertical column 42 to slide along the moving groove 217 when the transfer table 22 moves outwards without causing movement interference.

[0026] In this embodiment, the interception component 4 further includes a vertical column 42. Vertical columns 42 are provided at both ends of the marking table 1 corresponding to the transfer table 22. A slot 45 is formed at the top of the vertical column 42. A first insertion block 27 is fixed to the bottom of the electric rotating shaft 26, and the first insertion block 27 is slidably inserted into the slot 45. The bottom of the vertical column 42 is rotatably installed with a long plate 41 through a bearing, and the bottom of the second baffle 44 is rotatably installed at the other end of the long plate 41 through a rotating shaft. A chute 46 is formed on the surface of the marking table 1 near the bottom of the second baffle 44, and the long plate 41 slides along the chute 46. A transmission belt 43 is sleeved on the bottom of the vertical column 42, and the other pulley of the transmission belt 43 is rotatably installed on the surface of the long plate 41 near the bottom of the second baffle 44 through a rotating shaft. A first gear 47 is fixed to the bottom of the rotating shaft of the second baffle 44, and a second gear 48 is fixed to the surface of the other pulley of the transmission belt 43. The first gear 47 is meshed with the second gear 48. The directions of the first baffle 28 and the second baffle 44 differ by 90 degrees. When the opening end of the transfer table 22 rotates to correspond to the marking table 1, at this time, the first baffle 28 is in an open state, while the second baffle 44 is in a closed state. After the first insertion block 27 and the slot 45 of the vertical column 42 are horizontally inserted, the connection of this part can be realized by the movement of the transfer table 22 pushed by the first electric push rod 13. The insertion direction of the first insertion block 27 and the slot 45 is just the same as the moving direction of the transfer table 22. The electric rotating shaft 26 drives the first baffle 28 to rotate to close the outlet end of the transfer table 22. Through the rotation of the vertical column 42 and the transmission of the transmission belt 43, the first gear 47 and the second gear 48 are meshed and rotated to drive the second baffle 44 to rotate and open. At this time, the positions of the insertion block and the slot 45 are perpendicular to the moving direction of the transfer table 22. Therefore, when the moving frame 25 drives the first baffle 28 to move, the vertical column 42 and the long plate 41 will move together, extruding the outer side of the carton by the first baffle 28, cooperating with the back surface of the transfer table 22 to measure the width of the carton, and locking it in this position. Subsequently, the first baffle 28 is opened by the electric rotating shaft 26, and the second baffle 44 is closed. Because the positions of the first baffle 28 and the second baffle 44 are adjusted synchronously, when the carton moves to the position of the second baffle 44, the middle positions on both sides will just correspond to the laser device 36, so as to keep the marking position close to the middle area.

[0027] When using the device, the cartons are conveyed at intervals through a conventional conveying table. The transfer table 22 rotates outward to receive the cartons. The first electric push rod 13 pushes the transfer table 22 outward to prevent the transfer table 22 from being interfered by the marking table 1 and unable to rotate. Subsequently, the steering motor 23 drives the transfer table 22 to rotate, with the opening of the transfer table 22 facing outward, to receive the cartons sent by the conveying table. Since there are second insertion blocks 210 at both ends of the second limiting plate 29, after the rotation direction, the second insertion block 210 on the back can still be inserted into the insertion hole 12 of the first limiting plate 11. The screw rod 216 driven by the motor rotates to drive the second limiting plate 29 and the first limiting plate 11 to move synchronously, adjusting the thickness of both sides of the carton to keep the carton restricted when moving along the marking table 1 and the transfer table 22 without shifting, and keeping the second limiting plate 29 and the first limiting plate 11 on the transfer table 22 and the marking table 1 adjusted synchronously. Through the cooperation of the steering motor 23 and the first electric push rod 13, the transfer table 22 is brought close to the entrance end of the marking table 1, and the cartons are conveyed through the roller shafts of both. When the cartons enter from the entrance end of the transfer table 22, the top will be squeezed by the inclined plate 213, so the height of the top plate 211 will be adjusted to keep the top plate 211 in squeezing contact with the top of the carton. At the same time, the connecting plate 214 and the two vertical rods 215 will be adjusted in height synchronously, which will also drive the adjustment of the position of the cross beam 32 to keep the cross beam 32 corresponding to the height of the carton. At the same time, after the cross beam 32 is adjusted, through the rotation of the connecting rod 35, the laser device 36 is brought close to the middle position of the carton from the vertical direction. The moving groove 217 of the connecting plate 214 allows the vertical column 42 to slide along the moving groove 217 when the transfer table 22 moves outward without causing movement interference. When the open end of the transfer table 22 rotates to correspond to the marking table 1, at this time, the first baffle 28 is in the open state and the second baffle 44 is in the closed state. After the first insertion block 27 and the slot 45 of the vertical column 42 are horizontally inserted, the connection of this part can be realized by the movement of the first electric push rod 13 pushing the transfer table 22. The insertion direction of the first insertion block 27 and the slot 45 is just the same as the moving direction of the transfer table 22. The electric rotating shaft 26 drives the first baffle 28 to rotate to close the outlet end of the transfer table 22. Through the rotation of the vertical column 42 and the transmission of the transmission belt 43, the first gear 47 meshes with the second gear 48 to rotate, driving the second baffle 44 to rotate and open. At this time, the position of the insertion block and the slot 45 is perpendicular to the moving direction of the transfer table 22. So when the moving frame 25 drives the first baffle 28 to move, the vertical column 42 and the long plate 41 will move together, squeezing the outside of the carton by the first baffle 28, cooperating with the back of the transfer table 22 to measure the width of the carton and locking it in this position. Subsequently, the first baffle 28 is opened and the second baffle 44 is closed by the electric rotating shaft 26. Since the positions of the first baffle 28 and the second baffle 44 are adjusted synchronously, when the carton moves to the position of the second baffle 44, the middle positions on both sides will just correspond to the laser device 36.Thus, the marking position is kept close to the middle area, and the laser device 36 of the marking component 3 performs simultaneous marking operations on the middle areas on both sides of the carton. Finally, by opening the second baffle 44, the carton is sent out and received from the tail end of the marking table 1.

For those skilled in the art, it is obvious that the present invention is not limited to the details of the above-described exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms.
