Description

Technical Field

[0001] This invention relates to the field of packaging box printing technology, specifically to a hot stamping printing apparatus for packaging box products. Background Technology

[0002] Hot stamping printing equipment for packaging boxes is a device used to emboss some bright fonts or patterns on the packaging box surface. It generally uses materials such as gold foil to color the fonts and patterns, making them more beautiful and eye-catching. It is an important part of the packaging box production line.

[0003] Patent publication number CN214188908U discloses a hot stamping printing device for packaging boxes, including a main body and a drying mechanism on the outside of the main body. The drying mechanism includes a connecting block located on the outside of the main body. A first slot is formed on the inside of the connecting block, and a first spring is provided inside the first slot. The first spring is fixedly connected to the locking block. A second fixing block is connected to one end of the connecting block and is connected to one side surface of the main body. A rotating rod is connected to one side of the connecting block, and an air duct is provided on the surface of the rotating rod. An adjusting block is connected to one end of the rotating rod, and one end of the rotating rod passes through the connecting block. A second slot is formed on the outer surface of the inner side of the rotating rod of the connecting block. By setting up a drying mechanism, the problem of metal foil not drying and solidifying properly during the operation of the hot stamping printing device, which leads to the deformation of the printed pattern, is effectively avoided. Using this mechanism can save the time of natural air drying and improve the working efficiency of the device.

[0004] Currently, hot stamping printing equipment used for packaging boxes still has the following problems: Before hot stamping, it is necessary to cover the printing area and surrounding area with materials such as gold foil. Because the gold foil and other materials are lightweight, they are easily blown away by the airflow generated by the mechanical movement, which can lead to hot stamping printing failure. Therefore, it is necessary to design a hot stamping printing equipment that can automatically roll and prevent the gold foil from being blown away. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a hot stamping printing apparatus for packaging boxes, which solves the problem mentioned in the background art that requires covering the printing area and surrounding area with materials such as gold foil before hot stamping. Because such materials are lightweight, they are easily blown away by the airflow generated by mechanical movement, leading to hot stamping printing failure.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a hot stamping printing apparatus for packaging boxes, comprising a box body, wherein an impression device, an edge removal device, a fixing device, and a drying device are provided inside the box body; the impression device comprises a telescopic rod, an impression plate, a connecting rod, and a roller; the telescopic rod is fixed to both sides of the inner wall of the box body, the impression plate is fixed to the telescopic end of the telescopic rod, the top end of the connecting rod is hinged to the bottom surface of the impression plate, and the roller is rotatably mounted at the bottom end of the connecting rod. Before the hot stamping printing operation, gold foil and other materials are laid on the printing area. These materials are often lightweight and easily blown away by the airflow during the impression process, so manual rolling and bonding are required. The telescopic rod is activated, causing the impression plate to move downwards, and the impression plate presses down for printing. The impression plate pushes the connecting rod, and the connecting rod pushes the roller, which rolls over the impression area to press the gold foil onto the impression area, thereby pre-compacting and bonding the gold foil in advance to prevent the airflow from blowing away the gold foil and causing the hot stamping printing to fail.

[0007] According to the above technical solution, the imprinting device further includes a cylinder, a connecting plate, a spring rod, and a locking column. The cylinder is fixed to the side of the connecting rod, and the locking column is slidably installed on the bottom surface of the imprinting plate. The locking head of the locking column is located on the movement trajectory of the cylinder. The connecting plate is fixed to the front of the locking column. One end of the spring rod is fixed to the back of the connecting plate, and the other end of the spring rod is fixed to the front of the imprinting plate. When the imprinting plate is pressed down, the imprinting plate pushes the connecting rod to rotate, and the connecting rod drives the cylinder to rotate. The cylinder squeezes the locking head of the locking column and engages above the locking head of the locking column, thereby lifting the roller and avoiding affecting other subsequent operations of the imprinting part. When unlocking is required for the next printing, the connecting plate is pulled, and the connecting plate drives the spring rod to extend. The connecting plate pulls the locking column, causing the cylinder to disengage from the locking column. The roller will fall down by itself under the action of gravity for the next pre-compacting operation of the gold foil.

[0008] According to the above technical solution, the edge removal device includes a screw, a moving block, a telescopic sleeve, an inner empty box, a wiping block, a square plate, a semi-circular block, and a holding plate. The holding plate is fixed to the middle of the inner wall of the box. The screw is fixed to the output end of the motor, and the motor is fixed to the middle of the inner wall of the box. The moving block is threaded to the outer wall of the screw and slidably mounted on the bottom surface of the holding plate. The telescopic sleeve is fixed to the top surface of the moving block. A through transverse groove for the movement of the telescopic sleeve is formed on the top surface of the holding plate. The inner empty box is fixed to the top surface of the telescopic sleeve. The wiping block is slidably mounted on the inner wall of the inner empty box. The square plate is fixed to both ends of the wiping block. Two rectangular grooves are formed on the top surface of the holding plate. The semicircular blocks are staggered and fixed to the inner walls of two rectangular grooves. The semicircular blocks are located on the movement trajectory of the square plate. After the printing is completed, the motor is started. The motor drives the screw to rotate, the screw drives the moving block to move forward, the moving block drives the telescopic sleeve rod to move forward, the telescopic sleeve rod drives the inner empty box to move forward, the inner empty box drives the wiping block to move forward, and the wiping block drives the square plate to move forward. The square plate collides and squeezes the staggered semicircular blocks, causing the wiping block to move back and forth, thus allowing the wiping block to move in all directions. The wiping block is used to wipe away and clean the excess gold foil outside the hot stamping printing area, achieving the purpose of automatic cleaning, reducing the workload of the staff, and making the hot stamping printing speed faster.

[0009] According to the above technical solution, the edge removal device also includes bolts and pads. Stepped blocks are fixed at both ends of the inner empty box. The pads are slidably installed on the top surface of the holding plate. The bolts are threaded in the middle of the pads. The front end of the bolts is rotatably installed on the back of the inner empty box 34. The stepped blocks at both ends of the inner empty box are located on the movement trajectory of the pads. When hot stamping is performed on packaging boxes of different thicknesses, it is necessary to adjust the height of the inner empty box and the wiping blocks. At this time, the bolts can be turned to adjust the distance between the pads and the inner empty box. The height of the stepped blocks at both ends of the inner empty box can be adjusted by using the pads, thereby achieving the purpose of adjusting the height of the inner empty box and the wiping blocks. This makes the device more applicable and can fit packaging boxes of various thicknesses.

[0010] According to the above technical solution, the fixing device includes a base plate, a rebound column, a chamfered block, a lifting column, and a pressure block. A square placement groove is formed in the center of the top surface of the holding plate, and a square recess is formed in the inner wall of the square placement groove. The pressure block is slidably installed on the inner wall of the square recess. A spring is provided between the top surface of the pressure block and the inner wall of the square recess. The base plate is slidably installed on the inner wall of the box. The bottom end of the rebound column is fixed to the upper surface of the base plate, and the top end of the rebound column is fixed to the bottom surface of the holding plate. The chamfered block is fixed to the upper surface of the base plate and is located on the moving block trajectory. The lifting column is fixed to the upper surface of the base plate. A circular through-slot for the movement of the lifting column is formed on the bottom surface of the inner wall of the square recess. The pressure block is located on the trajectory of the lifting column. When the moving block moves towards the front of the holding plate, it presses against the chamfered block, causing the chamfered block to move downwards. The chamfered block then moves the base plate downwards, which in turn causes the return column to extend downwards. The base plate then moves the lifting column downwards, locking the edge of the packaging box into the bottom surface of the pressure block. Under the action of the spring force, the pressure block will hold the edge of the packaging box in place, preventing the packaging box from sliding during pressing and edge trimming, which could lead to product failure. When the moving block moves to the rear of the holding plate, the moving block and the chamfered block no longer contact each other. At this time, the return column retracts upwards, causing the base plate to move towards the holding plate. The base plate then moves the lifting column upwards, causing the lifting column to press against and squeeze the pressure block, thus lifting the pressure block and unlocking it.

[0011] According to the above technical solution, the fixing device further includes a rotating plate and a retractable spring plate. The bottom surface of the pressing block has a small groove. The rotating plate is rotatably installed on the inner wall of the small groove. The retractable spring plate is fixed on the inner wall of the small groove. The top surface of the telescopic end of the retractable spring plate is a beveled surface. The telescopic end of the retractable spring plate is located on the movement trajectory of the rotating plate. At the same time, when the pressing block is in a fixed state, the packaging box will be pressed by the rotating plate. The retractable spring plate restricts the rotation direction of the rotating plate, so that the rotating plate can only rotate from top to bottom towards the inside of the small groove, that is, it can only push the packaging box towards the inside of the small groove. When the packaging box is pulled, the rotating plate will be locked by the retractable spring plate to prevent the packaging box from moving when removing the edge, which would cause the packaging box to detach from the fixation and improve the fixation effect.

[0012] According to the above technical solution, the air-drying device includes a fan, an air outlet, louvers, gears, and a toothed plate. The fan is fixed to the top surface of the inner wall of the housing, the air outlet is fixed to the bottom surface of the fan, the louvers are rotatably installed on the inner wall of the air outlet, the gears are fixed to the outer wall of the louver shaft, and the toothed plate is slidably installed on the inner wall of the housing. The gears are located on the movement trajectory of the toothed plate. Before the edge removal is performed after the printing is completed, the metal parts need to be air-dried and solidified to ensure that the gold foil and the printing parts are bonded to a certain extent. Therefore, the fan needs to blow air onto the printing parts to increase the airflow. At the same time, the toothed plate is pushed and pulled, and the toothed plate drives the gear to rotate. The gear drives the louvers inside the air outlet to rotate back and forth. By adjusting the direction of the louvers, the air outlet angle is adjusted so that the airflow can be better directed to the printing parts, improving the air-drying efficiency and saving printing time.

[0013] According to the above technical solution, the air drying device also includes a push rod and a return air plate. The top end of the push rod is hinged to the bottom surface of the toothed plate, the return air plate is hinged to the inner wall of the box, and the bottom end of the push rod is hinged to the top surface of the return air plate. When the toothed plate moves, the toothed plate will push and pull the push rod, and the push rod will push and pull the return air plate. The return air plate guides and adjusts the airflow, preventing the imprinting device from blocking the airflow direction, so that the airflow can blow directly to the bottom imprinting area. It also facilitates the removal and cleaning of excess edge trimming waste, avoiding waste from contaminating the new packaging box and facilitating the next operation.

[0014] This invention provides a hot stamping printing apparatus for packaging box products. It has the following advantages:

[0015] (1) The present invention, through the setting of the printing device, enables the telescopic rod, printing plate, connecting rod and roller to cooperate. Before the hot stamping printing operation, gold foil and other materials are laid on the printing area. These materials are often light in weight and are easily blown away by the airflow during printing. The printing plate presses down to print, the printing plate pushes the connecting rod, the connecting rod pushes the roller, and the roller rolls over the printing area to press the gold foil onto the printing area, thereby pre-compacting and adhering the gold foil in advance, preventing the airflow from blowing away the gold foil and causing the hot stamping printing to fail. The cylinder, connecting plate, elastic rod and locking column cooperate. When the printing plate presses down, the cylinder squeezes the locking head of the locking column and locks into the top of the locking head of the locking column, thereby lifting the roller. This can avoid affecting other subsequent operations of the printing area. When the next printing needs to be unlocked, the connecting plate is pulled, the connecting plate drives the elastic rod to extend, the connecting plate pulls the locking column, so that the cylinder disengages from the locking column, and the roller will fall down by itself under the action of gravity, to carry out the next pre-compacting operation of the gold foil.

[0016] (2) The present invention, through the setting of the edge removal device, enables the screw, moving block, telescopic sleeve, inner empty box, wiping block, square plate, semi-circular block and holding plate to cooperate. The inner empty box drives the wiping block to move forward, the wiping block drives the square plate to move forward, the square plate collides and squeezes the staggered semi-circular blocks, so that the wiping block moves back and forth, so that the wiping block can move forward, backward and left and right. The wiping block is used to wipe and clean the excess gold foil outside the hot stamping printing area, so as to achieve the purpose of automatic cleaning, reduce the workload of workers, and make the hot stamping printing speed faster. The bolt and the pad are coordinated. Tightening the bolt adjusts the distance between the pad and the inner empty box. The height of the stepped blocks at both ends of the inner empty box is adjusted by using the pad, so as to adjust the height of the inner empty box and the wiping block. This makes the device more applicable and can fit packaging boxes of various thicknesses.

[0017] (3) The present invention, through the setting of the fixing device, enables the base plate, spring-loaded column, corner-cutting block, lifting column and pressure block to cooperate. When the moving block moves to the front end of the holding plate, the moving block squeezes the corner-cutting block, the corner-cutting block moves downward, the corner-cutting block drives the base plate to move downward, the base plate drives the spring-loaded column to extend downward, the base plate drives the lifting column to move downward, and the edge of the packaging box is stuck into the bottom surface of the pressure block. Under the action of spring force, the pressure block will press the edge of the packaging box to achieve the fixing effect, and prevent the packaging box from sliding during pressing and edge trimming, which would lead to the failure of the finished product. The rotating plate and the retractable spring plate cooperate, and the retractable spring plate restricts the rotation direction of the rotating plate, so that the rotating plate can only rotate from top to bottom towards the inside of the small groove, that is, it can only push the packaging box towards the inside of the small groove. When the packaging box is pulled, the rotating plate will be locked by the retractable spring plate, which prevents the packaging box from moving during edge trimming, causing the packaging box to fall off the fixing, and improves the fixing effect.

[0018] (4) The present invention, through the setting of the air drying device, enables the fan, air outlet, louver, gear and toothed plate to cooperate, push and pull the toothed plate, the toothed plate drives the gear to rotate, the gear drives the louver inside the air outlet to rotate back and forth, and by adjusting the direction of the louver, the air outlet angle can be adjusted so that the airflow can be better blown to the printing area, improving the air drying efficiency and saving printing time; the push rod and return air plate cooperate, the push rod will push and pull the return air plate, and the return air plate is used to guide and adjust the airflow, preventing the printing device from blocking the airflow direction, so that the airflow can blow directly to the bottom printing area, and at the same time, it is convenient to blow away and clean up the excess edge removal waste, avoid the waste from contaminating the new packaging box, and facilitate the next operation.

The roller 24 is rotated and installed at the bottom end of the connecting rod 23. The connecting rod 23 pushes the roller 24. The roller 24 rolls over the printing area and presses the gold foil onto the printing area, thereby pre-compacting and adhering the gold foil in advance to prevent the airflow from blowing away the gold foil and causing the hot stamping printing to fail.

[0031] The impression device 2 also includes a cylinder 25, a connecting plate 26, a spring rod 27, and a locking post 28. The cylinder 25 is fixed to the side of the connecting rod 23. When the impression plate 22 presses down, the impression plate 22 pushes the connecting rod 23 to rotate, and the connecting rod 23 drives the cylinder 25 to rotate. The locking post 28 is slidably installed on the bottom surface of the impression plate 22. The locking head of the locking post 28 is located on the movement trajectory of the cylinder 25. The cylinder 25 squeezes the locking head of the locking post 28 and engages with the top of the locking head of the locking post 28, thereby achieving the purpose of lifting the roller 24, thus enabling... To avoid affecting other subsequent operations on the printing area, the connecting plate 26 is fixed to the front of the locking post 28. When unlocking is required for the next printing, the connecting plate 26 is pulled. One end of the elastic rod 27 is fixed to the back of the connecting plate 26, and the other end of the elastic rod 27 is fixed to the front of the printing plate 22. The connecting plate 26 drives the elastic rod 27 to extend. The connecting plate 26 pulls the locking post 28, causing the cylinder 25 to disengage from the locking post 28. The roller 24 will fall down by itself under the action of gravity to carry out the next pre-compacting operation of the gold foil.

[0032] The edge removal device 3 includes a screw 31, a moving block 32, a telescopic sleeve 33, an inner empty box 34, a wiping block 37, a square plate 38, a semi-circular block 39, and a holding plate 310. The holding plate 310 is fixed to the middle of the inner wall of the box 1. The screw 31 is fixed to the output end of the motor, and the motor is fixed to the middle of the inner wall of the box 1. After the stamping is completed, the motor is started, and the motor drives the screw 31 to rotate. The moving block 32 is threaded to the outer wall of the screw 31 and is slidably installed on the bottom surface of the holding plate 310. The screw 31 drives the moving block 32 to move forward. The telescopic sleeve 33 is fixed to the top surface of the moving block 32. The top surface of the holding plate 310 has a through transverse groove for the movement of the telescopic sleeve 33. The moving block 32 drives the telescopic sleeve 33 to move forward. The inner empty box 34 is fixed to the top surface of the telescopic sleeve 33. The retracting rod 33 drives the inner empty box 34 to move forward. The wiping block 37 is slidably installed on the inner wall of the inner empty box 34. The inner empty box 34 drives the wiping block 37 to move forward. The square plate 38 is fixed at both ends of the wiping block 37. The inner wiping block 37 drives the square plate 38 to move forward. The top surface of the holding plate 310 has two rectangular grooves. The semi-circular blocks 39 are fixed alternately on the inner walls of the two rectangular grooves. The semi-circular blocks 39 are located on the movement trajectory of the square plate 38. The square plate 38 collides and squeezes the alternately arranged semi-circular blocks 39, causing the wiping block 37 to move back and forth. Thus, the wiping block 37 can move forward, backward, left and right. The wiping block 37 is used to wipe and clean the excess gold foil outside the hot stamping printing area, achieving the purpose of automatic cleaning, reducing the workload of the staff, and making the hot stamping printing speed faster.

[0033] The edge removal device 3 also includes bolts 35 and pads 36. Stepped blocks are fixed at both ends of the inner empty box 34. The pads 36 are slidably installed on the top surface of the holding plate 310. The bolts 35 are threadedly connected to the middle of the pads 36. When hot stamping is performed on packaging boxes of different thicknesses, it is necessary to adjust the height of the inner empty box 34 and the wiping blocks 37. At this time, the bolts 35 can be turned. The front end of the bolts 35 is rotated and installed on the back of the inner empty box 34. The stepped blocks at both ends of the inner empty box 34 are located on the movement trajectory of the pads 36. The distance between the pads 36 and the inner empty box 34 is adjusted by the bolts 35. The height of the stepped blocks at both ends of the inner empty box 34 is adjusted by the pads 36, thereby achieving the purpose of adjusting the height of the inner empty box 34 and the wiping blocks 37. This makes the device more applicable and can fit packaging boxes of various thicknesses.

[0034] In use, before the hot stamping printing operation, gold foil and other materials are laid on the printing area. These materials are often lightweight and easily blown away by the airflow during printing. Therefore, manual laying and rolling are required. The telescopic rod 21 is activated, causing the printing plate 22 to move downwards. The printing plate 22 then presses down for printing. The printing plate 22 pushes the connecting rod 23, which in turn pushes the roller 24. The roller 24 rolls over the printing area, pressing the gold foil onto it. This pre-pressing and bonding of the gold foil prevents the airflow from blowing it away and causing printing failure. Simultaneously, when the pressure... When the printing plate 22 is pressed down, the printing plate 22 pushes the connecting rod 23 to rotate, the connecting rod 23 drives the cylinder 25 to rotate, the cylinder 25 squeezes the locking head of the locking column 28 and engages above the locking head of the locking column 28, thereby lifting the roller 24 and avoiding affecting other subsequent operations of the printing part. When the next printing needs to be unlocked, the connecting plate 26 is pulled, the connecting plate 26 drives the elastic rod 27 to extend, the connecting plate 26 pulls the locking column 28, so that the cylinder 25 disengages from the locking column 28, and the roller 24 will fall down by itself under the action of gravity, to carry out the next pre-compacting operation of the gold foil.

[0035] After the stamping is completed, the motor is started. The motor drives the screw 31 to rotate, which in turn moves the moving block 32 forward. The moving block 32 then moves the telescopic sleeve 33 forward, which in turn moves the inner empty box 34 forward. The inner empty box 34 then moves the wiping block 37 forward, which in turn moves the square plate 38 forward. The square plate 38 collides with and presses against the staggered semicircular blocks 39, causing the wiping block 37 to move back and forth. This allows the wiping block 37 to move in all directions, including forward, backward, left, and right, to remove excess gold foil outside the hot stamping area. The wiping and cleaning process achieves automatic cleaning, reducing the workload of staff and making hot stamping printing faster. When hot stamping packaging boxes of different thicknesses, it is necessary to adjust the height of the inner empty box 34 and the wiping block 37. At this time, the bolt 35 can be turned to adjust the distance between the pad 36 and the inner empty box 34. The height of the stepped blocks at both ends of the inner empty box 34 can be adjusted by using the pad 36, thereby achieving the purpose of adjusting the height of the inner empty box 34 and the wiping block 37. This makes the device more applicable and can fit packaging boxes of various thicknesses.

[0036] Please see Figure 1-9 Based on the above embodiments, another embodiment of the present invention further includes a fixing device 4 and a drying device 5.

[0037] The fixing device 4 includes a base plate 41, a spring-loaded column 42, a chamfered block 43, a lifting column 44, and a pressure block 45. A square placement groove is formed in the center of the top surface of the holding plate 310, and a square recess is formed in the inner wall of the square placement groove. The pressure block 45 is slidably mounted on the inner wall of the square recess. A spring is provided between the top surface of the pressure block 45 and the inner wall of the square recess. The base plate 41 is slidably mounted on the inner wall of the box 1. The bottom end of the spring-loaded column 42 is fixed to the upper surface of the base plate 41, and the top end of the spring-loaded column 42 is fixed to the bottom surface of the holding plate 310. The chamfered block 43 is fixed to the upper surface of the base plate 41 and is located on the movement trajectory of the moving block 32. When the moving block 32 moves towards the front end of the holding plate 310, the moving block 32 presses against the chamfered block 43, causing the chamfered block 43 to move downwards. The chamfered block 43 drives the base plate 41 to move downwards, and the base plate 41 drives the spring-loaded column. 42 extends downwards, and the lifting column 44 is fixed to the upper surface of the base plate 41. The base plate 41 drives the lifting column 44 to move downwards. The bottom surface of the inner wall of the square groove is provided with a circular through slot for the movement of the lifting column 44. The pressure block 45 is located on the movement trajectory of the lifting column 44. The edge of the packaging box is inserted into the bottom surface of the pressure block 45. Under the action of spring force, the pressure block 45 will press the edge of the packaging box to achieve the function of fixing, so as to prevent the packaging box from sliding during heat pressing and edge trimming, which would lead to the failure of the finished product. When the moving block 32 moves to the rear end of the holding plate 310, the moving block 32 and the corner block 43 do not contact each other. At this time, the return column 42 retracts upwards. The return column 42 drives the base plate 41 to move towards the holding plate 310. The base plate 41 drives the lifting column 44 to move upwards. The lifting column 44 abuts against and squeezes the pressure block 45, causing the pressure block 45 to lift up, thereby achieving the purpose of unlocking.

[0038] The fixing device 4 also includes a rotating plate 46 and a retractable spring plate 47. The bottom surface of the pressure block 45 has a small groove. The rotating plate 46 is rotatably installed on the inner wall of the small groove. The retractable spring plate 47 is fixed on the inner wall of the small groove. The top surface of the telescopic end of the retractable spring plate 47 is a beveled surface. The telescopic end of the retractable spring plate 47 is located on the movement trajectory of the rotating plate 46. When the pressure block 45 is in a fixed state, the packaging box will be pressed by the rotating plate 46. The retractable spring plate 47 restricts the rotation direction of the rotating plate 46, so that the rotating plate 46 can only rotate from top to bottom towards the inside of the small groove, that is, it can only push the packaging box towards the inside of the small groove. When the packaging box is pulled, the rotating plate 46 will be locked by the retractable spring plate 47 to prevent the packaging box from moving when removing the edge, which would cause the packaging box to fall off the fixing and improve the fixing effect.

[0039] The air-drying device 5 includes a fan 51, an air outlet 52, a louvered plate 53, a gear 54, and a toothed plate 55. The fan 51 is fixed to the top surface of the inner wall of the housing 1. Before the edge removal is performed after the printing is completed, the metal parts need to be air-dried and solidified so that the gold foil and the printing parts are bonded to a certain extent. Therefore, the fan 51 needs to blow air onto the printing parts to increase the airflow of the printing parts. The air outlet 52 is fixed to the bottom surface of the fan 51. The louvered plate 53 is rotatably installed on the inner wall of the air outlet 52. The gear 54 is fixed to the outer wall of the louvered plate 53's rotating shaft. The toothed plate 55 is slidably installed on the inner wall of the housing 1. Pushing and pulling the toothed plate 55 causes the gear 54 to be located on the movement trajectory of the toothed plate 55. The toothed plate 55 drives the gear 54 to rotate. The gear 54 drives the louvered plate 53 inside the air outlet 52 to rotate back and forth. By adjusting the direction of the louvered plate 53, the air outlet angle is adjusted so that the airflow can be better directed to the printing parts, improving the air-drying efficiency and saving printing time.

[0040] The air drying device 5 also includes a push rod 56 and a return air plate 57. The top end of the push rod 56 is hinged to the bottom surface of the toothed plate 55. When the toothed plate 55 moves, it pushes and pulls the push rod 56. The return air plate 57 is hinged to the inner wall of the box 1, and the bottom end of the push rod 56 is hinged to the top surface of the return air plate 57. The push rod 56 pushes and pulls the return air plate 57, using the return air plate 57 to guide and adjust the airflow, preventing the imprinting device 2 from blocking the airflow direction, so that the airflow can blow directly to the bottom imprinting area. It also facilitates the removal and cleaning of excess edge trimming waste, avoiding waste from contaminating the new packaging box and facilitating the next operation.

[0041] In use, when the moving block 32 moves towards the front end of the holding plate 310, the moving block 32 presses against the corner-cutting block 43, causing the corner-cutting block 43 to move downwards. The corner-cutting block 43 drives the base plate 41 to move downwards, which in turn drives the return column 42 to extend downwards. The base plate 41 then drives the lifting column 44 to move downwards, locking the edge of the packaging box into the bottom surface of the pressure block 45. Under the action of the spring force, the pressure block 45 will press down on the edge of the packaging box to achieve a fixing effect, preventing the packaging box from sliding during pressing and edge trimming, which could lead to product failure. When the moving block 32 moves to the rear end of the holding plate 310, the moving block 32 and the corner-cutting block 43 are no longer in contact. At this time, the return column 42 retracts upwards. 42 drives the base plate 41 to move towards the holding plate 310. The base plate 41 drives the lifting column 44 to move upward. The lifting column 44 abuts against and squeezes the pressure block 45, causing the pressure block 45 to lift, thereby achieving the purpose of unlocking. At the same time, when the pressure block 45 is in a fixed state, the packaging box will be pressed by the rotating plate 46. The retractable spring plate 47 restricts the rotation direction of the rotating plate 46, so that the rotating plate 46 can only rotate from top to bottom towards the inside of the small groove, that is, it can only push the packaging box towards the inside of the small groove. When the packaging box is pulled, the rotating plate 46 will be locked by the retractable spring plate 47 to prevent the packaging box from moving when removing the edge, causing the packaging box to fall off the fixed position, thus improving the fixing effect.

[0042] Before removing the edges after the printing process, the metal parts need to be air-dried and solidified to ensure the gold foil and the printing area are bonded to a certain extent. Therefore, the blower 51 is needed to blow air onto the printing area to increase the airflow. At the same time, the toothed plate 55 is pushed and pulled, which drives the gear 54 to rotate. The gear 54 drives the louvered plate 53 inside the air outlet 52 to rotate back and forth. By adjusting the direction of the louvered plate 53, the air outlet angle is adjusted so that the airflow can be better directed to the printing area, improving drying efficiency and saving printing time. When the toothed plate 55 moves, it pushes and pulls the push rod 56, which in turn pushes and pulls the return air plate 57. The return air plate 57 guides and adjusts the airflow to prevent the printing device 2 from blocking the airflow direction, allowing the airflow to blow directly onto the bottom printing area. It also facilitates the removal and cleaning of excess edge removal waste, preventing waste from contaminating the new packaging box and facilitating the next operation.
