Description

Technical Field

[0001] This invention relates to the field of paperboard manufacturing technology, and in particular to a drying apparatus for water-based printed paperboard. Background Technology

[0002] With increasingly stringent environmental protection requirements, water-based inks are gaining wider application in the paperboard printing industry due to their advantages such as low VOC emissions and environmental friendliness. However, water-based inks have an inherent drawback of slow drying speed. If the printed paperboard is not fully dried, problems such as ink sticking and surface scratches can easily occur, directly affecting the quality of subsequent processing. Currently, there is usually a lack of dedicated integrated drying and conveying equipment between paperboard printing and slotting / die-cutting processes: some production scenarios use natural air drying, which is extremely inefficient and cannot meet the needs of large-scale production; some use simple hot air drying devices, but these devices only achieve the drying function and do not consider the positioning requirements of the paperboard during the conveying process. This causes the paperboard to easily shift and warp when entering the slotting / die-cutting equipment, resulting in problems such as die-cutting size deviation and inaccurate slotting position, significantly increasing the scrap rate. In addition, existing drying devices and positioning mechanisms are mostly set up independently, which is cumbersome to connect, occupies a large space, and requires additional conveying components, resulting in a discontinuous production process and high equipment investment costs, making it difficult to meet the high-efficiency and precise production requirements of modern paperboard processing. Therefore, this paper proposes a paperboard drying device after water-based printing to solve the above problems. Summary of the Invention

[0003] This invention addresses the problems of low drying efficiency, insufficient positioning accuracy, and cumbersome equipment connection in existing technologies by providing a water-based post-printing paperboard drying device. This device integrates hot air drying and conveying functions, directly connecting printing equipment and slotting / die-cutting equipment without the need for additional independent drying devices and conveying components. It enables continuous operation of printing, drying, positioning, and conveying, significantly shortening the production cycle and effectively meeting the high-efficiency requirements of large-scale production. This invention effectively solves the problems mentioned in the background art.

[0004] The technical solution adopted by the present invention to solve the above problems is as follows: A water-based post-printing paperboard drying device includes a conveyor base, on which a printing machine and a slotting machine are respectively located on both sides. A flow bed is located at the upper end of the conveyor base, and multiple hot air pipes are also located at the upper end of the conveyor base. Multiple air blowers inclined along the moving direction of the paperboard are provided on the outer surface of each hot air pipe. When the paperboard moves from the printing machine into the flow bed, the air blowers can blow the paperboard, and the paperboard can be dried while moving to one side along the flow bed. A positioning platform is also located at the upper end of the conveyor base, and a positioning clamp is provided on the positioning platform. The positioning clamp includes multiple positioning rods and a rotatable drive disk. When the drive disk rotates, it can move the multiple positioning rods inward.

[0005] The inner wall of the flow bed is provided with multiple limiting strips, and a conveying roller connected to the positioning table is also provided on one side of the flow bed.

[0006] The positioning platform has two long sliders slidably connected to the inner walls on both sides. The positioning rods are rotatably connected to the corresponding long sliders. A horizontal connecting rod is provided at the lower end of each of the two long sliders. Two centrally symmetrical first connecting rods are hinged at the non-center position of the upper surface of the drive disk. The outer ends of the two first connecting rods are hinged to the corresponding horizontal connecting rods.

[0007] The upper end of the conveyor seat is provided with a movable U-shaped drive seat, the upper end of the U-shaped drive seat is provided with a drive pin, and the lower end of the drive disk is coaxially fixed with a swing arm, and the swing arm is provided with a long keyway that cooperates with the drive pin.

[0008] The upper end of the U-shaped drive seat is provided with a rotatable threaded rod, and an adjusting seat that is slidably connected to the U-shaped drive seat is threaded on the outer surface of the threaded rod. The drive pin is installed on the adjusting seat.

[0009] The inner wall of the U-shaped drive seat is provided with a first sliding pin, and the upper end of the conveyor seat is provided with a rotatable positioning disc cam. The upper surface of the positioning disc cam is provided with a variable diameter groove and a large arc groove that cooperate with the first sliding pin.

[0010] The lower end of the positioning platform is provided with a rectangular frame that can move left and right. A pusher plate is provided on one side of the upper end of the positioning platform, and two stop bars are provided on the other side of the upper end of the positioning platform. When the rectangular frame moves to the right, it can drive the pusher plate to move to the right and forward at the same time, and the stop bars to move outward and downward at the same time.

[0011] The pusher plate is slidably connected to the inner wall of the rectangular frame. Short pins are provided on both ends of the pusher plate. Two track frames are provided on the lower surface of the positioning table. The inner wall of each track frame is provided with a first short inclined groove and a first long transverse groove that cooperate with the short pins.

[0012] The positioning platform has two square sleeves slidably connected to its inner wall. The stop rods are slidably connected to the inner wall of the square sleeves. The lower surface of the positioning platform has two guide plates that are fixed to the corresponding square sleeves. Long pins are provided on both sides of the rectangular frame. The inner wall of the guide plates is provided with a second short oblique groove and a second long horizontal groove that cooperate with the long pins. The lower surface of the positioning platform is also fixed with two guide seats. The lower end of the stop rods is provided with a third sliding pin. The inner wall of the guide seats is provided with a third oblique groove that cooperates with the third sliding pin.

[0013] The inner wall of the rectangular frame is provided with a second sliding pin, and the upper end of the conveyor seat is provided with a rotatable drive shaft. A pusher disc cam is fixedly connected to the outer surface of the drive shaft. The upper surface of the pusher disc cam is provided with a small arc groove and a protrusion that cooperate with the second sliding pin.

[0014] Compared with the prior art, the present invention has the following advantages: During operation, the blower head moves the cardboard within the flow bed along its inner wall to one side, simultaneously drying the cardboard. When the cardboard reaches the positioning table, positioning fixtures (positioning rods, drive discs, etc.) clamp the cardboard, preventing deviations during die-cutting in the slotting machine. This device integrates hot air drying and conveying functions, directly connecting printing and slotting / die-cutting equipment without requiring separate drying or conveying components. It enables continuous printing, drying, positioning, and conveying, significantly shortening the production cycle and effectively meeting the high-efficiency demands of large-scale production. The directional hot air blowing method for targeted drying of the printed cardboard quickly cures water-based inks, preventing ink adhesion, surface scratches, and ensuring stable printing quality. This device provides a good foundation for subsequent slotting and die-cutting processes. The addition of a clamping and positioning mechanism before the cardboard enters the die-cutting machine effectively corrects deviations caused by airflow impact and warping during cardboard transport, ensuring the cardboard enters the slotting and die-cutting equipment with a precise orientation. This significantly reduces scrap rates caused by die-cutting size deviations and inaccurate slotting positions, improving the finished product qualification rate. The device integrates drying, conveying, and positioning functions into one compact structure, minimizing space requirements and reducing equipment footprint. It also simplifies the production process, eliminating the need for separate positioning and conveying equipment, reducing equipment purchase and installation costs, and improving production cost-effectiveness. The device can adjust hot air speed, drying time, and clamping and positioning parameters according to different cardboard specifications, adapting to the processing needs of various cardboard sizes. Furthermore, the overall connection is smooth, requiring no complex manual intervention, reducing operational difficulty and improving the stability and controllability of the production process.

Detailed Implementation

[0031] The following are specific embodiments of the present invention, and the technical solutions of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0032] like Figures 1-15 As shown, the present invention provides a water-based printing paperboard drying device, including a conveyor seat 1. A printing machine 2 and a slotting machine 3 are respectively provided on both sides of the conveyor seat 1. A flow bed 6 is provided at the upper end of the conveyor seat 1. A plurality of hot air pipes 4 are also provided at the upper end of the conveyor seat 1. A plurality of air blowers 5 inclined along the moving direction of the paperboard are provided on the outer surface of the hot air pipes 4. When the paperboard moves from the printing machine 2 into the flow bed 6, the air blowers 5 can blow the paperboard. The paperboard can be dried while moving to one side along the flow bed 6. A positioning platform 9 is also provided at the upper end of the conveyor seat 1. A positioning fixture is provided on the positioning platform 9. The positioning fixture includes a plurality of positioning rods 28. The positioning fixture also includes a rotatable drive disk 24. When the drive disk 24 rotates, it can move the plurality of positioning rods 28 inward.

[0033] like Figures 1-9As shown, the printing press 2, slotting machine 3, and conveyor 1 are all placed on the ground. The printing press 2 is capable of printing on cardboard, and the slotting machine 3 is capable of slotting the cardboard. Both the printing press 2 and the slotting machine 3 are existing technologies and will not be described in detail. The flow bed 6 restricts the cardboard from the printing press 2 to move only along the direction of the flow bed 6. The lower ends of the hot air pipes 4 are all connected to blowers or pressure tanks, which enable the blowers 5 to continuously blow out hot air. The blowers 5 are evenly arranged at the upper and lower ends of the flow bed 6, and the blowers 5 are inclined, so that when the blowers 5 are working, they can blow the cardboard inside the flow bed 6. The paperboard moves to one side along the inner wall of the flow bed 6, and is dried simultaneously with the blowing process. When the paperboard in the flow bed 6 reaches the positioning table 9, it is clamped and positioned by the positioning fixtures, namely the positioning rod 28 and the drive disk 24. When the drive disk 24 rotates, it drives the positioning rod 28 to move inward, thus preventing deviation when entering the slotting machine 3 for die cutting. This device integrates hot air drying and conveying functions, directly connecting the printing equipment and the slotting and die-cutting equipment. It eliminates the need for separate drying devices and conveying components, achieving continuous printing, drying, positioning, and conveying. This process significantly shortens the production cycle and effectively meets the high-efficiency requirements of large-scale production. Targeted drying of the printed cardboard using directional hot air blowing quickly cures the water-based ink, preventing ink sticking and surface scratches, ensuring stable printing quality, and providing a good foundation for subsequent slotting and die-cutting processes. Adding a clamping and positioning mechanism before the cardboard enters the die-cutting machine effectively corrects deviations caused by airflow impact and warping during transport, ensuring the cardboard enters the slotting and die-cutting equipment with precise orientation, significantly reducing die-cutting dimensional deviations and inaccurate slotting positions. This device reduces scrap rates caused by issues such as high product defect rates and improves finished product qualification rates. It integrates drying, conveying, and positioning functions into a single unit with a compact design and small footprint, reducing the equipment's floor space. Simultaneously, it simplifies the production process, eliminating the need for separate positioning and conveying equipment, thus lowering equipment purchase and installation costs and improving production cost-effectiveness. The device can adjust hot air speed, drying time, and clamping and positioning parameters according to different cardboard specifications, adapting to the processing needs of various cardboard sizes. Furthermore, its seamless integration eliminates the need for complex manual intervention, reducing operational difficulty and enhancing the stability and controllability of the production process.

[0034] The inner wall of the flow bed 6 is provided with multiple limiting strips 7, and a conveying roller 8 connected to the positioning table 9 is also provided on one side of the flow bed 6.

[0035] like Figure 3 and Figure 5As shown, the flow bed 6 is fixed to the upper surface of the conveyor seat 1. The limiting bar 7 is a cylindrical rod, which is welded to the inner wall of the flow bed 6. The cylindrical rods are arranged in a set at the top and bottom, and multiple sets are arranged horizontally. There is a gap between the upper and lower sets of limiting rods, which allows the paper to move on the inner wall of the flow bed 6. When the paper moves to one side into the conveyor roller 8, the conveyor roller 8 can transport the paper to the positioning table 9 when it is working, so that the paper moves more smoothly. The conveyor roller 8 is existing technology and will not be described in detail.

[0036] The inner walls on both sides of the positioning platform 9 are slidably connected to two long sliders 27, and the positioning rods 28 are rotatably connected to the corresponding long sliders 27. The lower end of each of the two long sliders 27 is provided with a horizontal connecting rod 26. The upper surface of the drive disk 24 is hinged to two centrally symmetrical first connecting rods 25 at the non-center position, and the outer ends of the two first connecting rods 25 are hinged to the corresponding horizontal connecting rods 26.

[0037] like Figure 6 and Figure 9 As shown, the long slider 27 can slide back and forth on the inner wall of the positioning platform 9. The positioning rod 28 is rotatably connected to the upper end of the long slider 27. After the positioning rod 28 clamps and positions the cardboard on the upper end of the positioning platform 9, the positioning rod 28 can rotate when pushing the cardboard, thereby reducing friction with the cardboard and preventing deformation or damage to both sides of the cardboard. Through the set horizontal connecting rod 26 and the first connecting rod 25, when the drive disk 24 rotates, it can drive the inner ends of the two first connecting rods 25 to move circumferentially. The outer ends of the two first connecting rods 25 will drive the horizontal connecting rod 26, the long slider 27, and the positioning rod 28 to move inward, thereby clamping and positioning the cardboard. When the drive disk 24 rotates in the reverse direction to reset, it can cause the positioning rod 28 to move outward, that is, it no longer clamps the cardboard.

[0038] The upper end of the conveyor seat 1 is provided with a movable U-shaped drive seat 15, the upper end of the U-shaped drive seat 15 is provided with a drive pin 19, and the lower end of the drive disk 24 is coaxially fixed with a swing arm 20, and the swing arm 20 is provided with a long keyway 21 that cooperates with the drive pin 19.

[0039] like Figures 9-10As shown, a U-shaped support 23 is fixedly connected to the upper surface of the conveyor seat 1, and a circular sleeve 22 is fixedly connected to the inner wall of the center of the drive disk 24. The circular sleeve 22 is rotatably connected to the inner wall of the U-shaped support 23, and the swing arm 20 is fixedly connected to the lower end of the outer surface of the circular sleeve 22. This is equivalent to the drive disk 24 and the swing arm 20 being coaxially fixedly connected, so that when the swing arm 20 swings, the drive disk 24 can rotate, and the circular sleeve 22 is rotatably connected to the inner wall of the U-shaped support 23, which can limit the movement of the drive disk 24 and the swing arm 20. Arm 20 can only rotate; U-shaped drive seat 15 can slide left and right on the upper surface of conveyor seat 1. When U-shaped drive seat 15 moves left and right, it can cause drive pin 19 to move left and right. When drive pin 19 moves left and right, it can drive swing arm 20 to swing back and forth through engagement with long keyway 21. When swing arm 20 swings back and forth, it can cause drive disk 24 to rotate forward and backward, thereby driving the corresponding positioning rod 28 to close inward or open outward.

[0040] The upper end of the U-shaped drive seat 15 is provided with a rotatable threaded rod 17. An adjusting seat 18 that is slidably connected to the U-shaped drive seat 15 is threaded on the outer surface of the threaded rod 17. A drive pin 19 is installed on the adjusting seat 18.

[0041] like Figure 10 As shown, bearing seats are rotatably connected to both ends of the outer surface of the threaded rod 17. The bottom ends of the bearing seats are fixed to the upper surface of the U-shaped drive seat 15, limiting the rotation of the threaded rod 17 to the upper end of the U-shaped drive seat 15. A handle 16 is also fixed to one side of the outer surface of the threaded rod 17, which facilitates the rotation of the threaded rod 17. The adjusting seat 18 is slidably connected to the inner wall of the U-shaped drive seat 15, and the drive pin 19 is fixed to the upper surface of the adjusting seat 18. When the threaded rod 17 rotates, it can drive the adjusting seat 18 and the drive pin 19 to move forward or backward under the threaded connection with the adjusting seat 18. When the drive pin 19 moves forward or backward, it can change the initial position of meshing with the long keyway 21. Under the threaded connection between the threaded rod 17 and the adjusting seat 18, it has a self-locking function, that is, when the threaded rod 17 does not rotate, the adjusting seat 18 and the drive pin 19 are locked. The moving pin 19 is fixed at the upper end of the U-shaped drive seat 15. That is, when the U-shaped drive seat 15 moves left and right, it can drive the adjusting seat 18 and the drive pin 19 to move back and forth. When the drive pin 19 moves back and forth, it can drive the swing arm 20 and the drive disk 24 to rotate forward and backward under the engagement with the long keyway 21. When the threaded rod 17 is rotated to adjust the position of the drive pin 19, the drive pin 19 can change the initial position of engagement with the long keyway 21 when it moves forward or backward. That is, when the U-shaped drive seat 15 and the drive pin 19 move back and forth, the swing arm 20 can be changed to change the swing angle of the drive disk 24, and the positioning rod 28 can also be changed to change the stroke of the inward closing and outward opening. It can be adjusted adaptively according to the size of the cardboard, that is, the positioning fixture can be adjusted according to the size of the cardboard.

[0042] The inner wall of the U-shaped drive seat 15 is provided with a first sliding pin 14, and the upper end of the conveying seat 1 is provided with a rotatable positioning disc cam 11. The upper surface of the positioning disc cam 11 is provided with a variable diameter groove 12 and a large arc groove 13 that cooperate with the first sliding pin 14.

[0043] like Figures 10-11 As shown, the first sliding pin 14 is fixed to the inner wall of the U-shaped drive seat 15, meaning the first sliding pin 14 can only move left and right. The installation and shape of the first sliding pin 14, the variable diameter groove 12, and the large arc groove 13 are as follows. Figure 11 As shown, when the positioning disc cam 11 rotates, it engages with the variable diameter groove 12, causing the first sliding pin 14 and the U-shaped drive seat 15 to move to the right. When the U-shaped drive seat 15 moves to the right, it drives the positioning rod 28 to close inward, thus clamping and positioning the cardboard on the upper end of the positioning table 9. When the positioning disc cam 11 continues to rotate, causing the first sliding pin 14 to enter the inner wall of the large arc groove 13, the first sliding pin 14 and the U-shaped drive seat 15 move to the top position to the right, that is, the corresponding positioning rod 28 moves inward. When the inner side moves to the top position, as the positioning disc cam 11 continues to rotate, the first sliding pin 14 remains at the rightmost position due to the engagement of the first sliding pin 14 with the large arc groove 13, meaning the positioning rod 28 remains in the innermost clamping state. When the positioning disc cam 11 continues to rotate, the first sliding pin 14 can enter the inner wall of the next diameter-changing groove 12. At this time, the first sliding pin 14 and the U-shaped drive seat 15 can move to the left, meaning the corresponding positioning rod 28 can move outward and open, allowing for repeated cyclic use.

[0044] The lower end of the positioning platform 9 is provided with a rectangular frame 34 that can move left and right. One side of the upper end of the positioning platform 9 is provided with a pusher plate 35, and the other side of the upper end of the positioning platform 9 is provided with two stop bars 45. When the rectangular frame 34 moves to the right, it can drive the pusher plate 35 to move to the right and forward at the same time, and the stop bars 45 to move outward and downward at the same time.

[0045] like Figure 6 and Figure 12As shown, multiple support columns are fixed to the lower surface of the positioning table 9, and the lower ends of the support columns are all fixed to the upper surface of the conveyor seat 1. The support columns support and fix the positioning table 9. A sliding seat is fixed to the upper end of the rectangular frame 34. The sliding seat is slidably connected to the lower surface of the positioning table 9, that is, the rectangular frame 34 can only move left and right at the lower end of the positioning table 9. When the cardboard on the upper end of the positioning table 9 is clamped and positioned, when the rectangular frame 34 moves to the right, it can drive the pusher plate 35 to move upward and to the right at the same time. When the pusher plate 35 moves upward, it can move out to the upper surface of the positioning table 9. When it moves to the right, it can push the cardboard on the upper end of the positioning table 9. When the rectangular frame 34 moves to the right, it can also push the cardboard on the upper end of the positioning table 9. Multiple stop bars 45 can move outward and downward simultaneously. When moving downward, they can enter the positioning table 9, thus preventing the cardboard from moving to the right. When the pusher plate 35 continues to move to the right, it can push the positioned cardboard into the slotting machine 3, thereby performing precise die-cutting on the cardboard. When the pusher plate 35 is at the leftmost position, it is at the bottommost position, i.e., the inner wall of the positioning table 9. At this time, the cardboard flowing out from the flow bed 6 can be moved into the positioning table 9. When the stop bar 45 is at the innermost end, the stop bar 45 can move out to the top of the positioning table 9, thus blocking the cardboard and preventing it from moving excessively to the right, so that the positioning rod 28 can clamp and position the cardboard.

[0046] The pusher plate 35 is slidably connected to the inner wall of the rectangular frame 34. Short pins 36 are provided on both ends of the pusher plate 35. Two track frames 37 are provided on the lower surface of the positioning table 9. The inner wall of each track frame 37 is provided with a first short inclined groove 38 and a first long transverse groove 39 that cooperate with the short pins 36.

[0047] like Figure 14 As shown, the pusher plate 35 can slide up and down on the inner wall of the rectangular frame 34. The short pin 36 is fixed on the front and rear end surfaces of the pusher plate 35. The bottom of the track frame 37 is fixed to the lower end surface of the positioning table 9. When the rectangular frame 34 moves to the right, it can drive the pusher plate 35, the short pin 36, etc. to move to the right simultaneously. When the short pin 36 moves to the right, it can move to the right and up at the same time through engagement with the first short inclined groove 38. That is, the corresponding short pin 36 and pusher plate 35 move to the right and up at the same time, so that the pusher plate 35 moves up to the upper end surface of the positioning table 9, which is convenient for pushing the cardboard. When the rectangular frame 34 continues to move to the right, it can drive the pusher plate 35, the short pin 36, etc. to continue to move to the right. When the short pin 36 moves to the right and meets the inner wall of the first long horizontal groove 39, the short pin 36 and pusher plate 35 move up to the top position. That is, at this time, the pusher plate 35 moves to the right at the top position, thus pushing the cardboard into the slotting machine 3.

[0048] The positioning platform 9 has two square sleeves 44 slidably connected to its inner wall. The stop rods 45 are slidably connected to the inner wall of the square sleeves 44. The lower surface of the positioning platform 9 has two guide plates 41 that are fixed to the corresponding square sleeves 44. The rectangular frame 34 has long pins 40 on both sides. The inner wall of the guide plates 41 has a second short oblique groove 42 and a second long horizontal groove 43 that cooperate with the long pins 40. The lower surface of the positioning platform 9 also has two guide seats 47 fixedly connected to it. The lower end of the stop rods 45 has a third sliding pin 46. The inner wall of the guide seats 47 has a third oblique groove 48 that cooperates with the third sliding pin 46.

[0049] like Figures 12-13 As shown, the square sleeve 44 can slide back and forth on the inner wall of the positioning platform 9, and the guide plate 41 can slide back and forth on the lower surface of the positioning platform 9. The square sleeve 44 is fixed to one side of the guide plate 41. That is, when the guide plate 41 moves back and forth, it can drive the square sleeve 44 and the stop rod 45 to move back and forth. Support plates are fixed to the outer surface of the long pin 40. The support plates are fixed to the two end faces of the rectangular frame 34. That is, the long pin 40 is fixed to the rectangular frame 34. When the rectangular frame 34 moves left and right, it can drive the long pin 40 to move left and right. The stop rod 45 can slide up and down. On the inner wall of the square sleeve 44, the third sliding pin 46 is fixed to the lower inner wall of the stop rod 45. When the square sleeve 44, the stop rod 45, and the third sliding pin 46 move outward, the stop rod 45 can move downward while moving outward through the engagement of the third sliding pin 46 and the third inclined groove 48. When the rectangular frame 34 and the long pin 40 move to the right, the guide plate 41, the square sleeve 44, and the stop rod 45 can be driven to move outward synchronously through the engagement of the second short inclined groove 42. When the stop rod 45 moves outward, the engagement of the third sliding pin 46 and the third inclined groove 48... The device allows the stop bar 45 to move outwards and downwards simultaneously. When the rectangular frame 34, long pin 40, etc., continue to move to the designated position to the right, that is, when the long pin 40 enters the inner wall of the second long transverse groove 43 from the inner wall of the second short inclined groove 42, the guide plate 41, square sleeve 44, stop bar 45, etc., move outwards to the top position, that is, the stop bar 45 moves into the inner wall of the positioning table 9 and no longer obstructs the cardboard. When the rectangular frame 34 continues to move to the right, the pusher plate 35 can push the cardboard into the slotting machine 3; that is, when the rectangular frame 34 moves from left to right, the pusher plate 35 can move outwards and downwards simultaneously. As the upper moving side moves to the right, the pusher plate 35 moves out to the upper end face of the positioning table 9. At the same time, the stop rod 45 can move outward and downward at the same time. The stop rod 45 moves into the inner wall of the positioning table 9. When the rectangular frame 34 continues to move to the right, the pusher plate 35 can push the cardboard into the slotting machine 3. When the rectangular frame 34 moves from right to left to reset, the pusher plate 35 can move to the left to reset. When it moves to the designated position to the left, the pusher plate 35 can move to the left and downward at the same time. At the same time, the stop rod 45 can move upward and inward at the same time, that is, reset to the initial state.

[0050] The inner wall of the rectangular frame 34 is provided with a second sliding pin 32, and the upper end of the conveying seat 1 is provided with a rotatable drive shaft 29. A pusher disc cam 30 is fixedly connected to the outer surface of the drive shaft 29. The upper surface of the pusher disc cam 30 is provided with a small arc groove 31 and a protrusion 33 that cooperate with the second sliding pin 32.

[0051] like Figure 7 or Figure 11 or Figure 14 As shown, the second sliding pin 32 is fixed to the inner wall of the rectangular frame 34, that is, when the second sliding pin 32 moves left and right, it can drive the rectangular frame 34 to move left and right; a motor 10 is fixedly connected to the lower surface of the conveyor seat 1, and the drive shaft 29 is fixedly connected to the output end of the motor 10. The function of the motor 10 is to provide rotational power to the drive shaft 29. The motor 10 is existing technology and will not be described in detail; when the drive shaft 29 rotates, it can drive the pusher disc cam 30 to rotate. When the pusher disc cam 30 rotates, it passes through the small arc groove 31 and the convex When the groove 33 engages with the second sliding pin 32, the second sliding pin 32 and the rectangular frame 34 can move back and forth left and right. That is, when the pusher disc cam 30 rotates, the second sliding pin 32 and the rectangular frame 34 can be kept stationary at the leftmost position through the engagement of the second sliding pin 32 with the small arc groove 31. When the pusher disc cam 30 continues to rotate and the second sliding pin 32 enters the inner wall of the convex groove 33, the second sliding pin 32 and the rectangular frame 34 can be moved to the right. After moving to the top of the right, they will move to the left. When the pusher disc cam 30 continues to rotate, the second sliding pin 32 can re-enter the inner wall of the small arc groove 31, meaning the second sliding pin 32, rectangular frame 34, etc., are in a stationary state at the leftmost position. The positioning disc cam 11 is fixed to the lower end of the outer surface of the drive shaft 29. Through the cooperation of the positioning disc cam 11 and the pusher disc cam 30, when the drive shaft 29 rotates, the positioning fixture can be activated first, meaning the two positioning rods 28 move inward and close, aligning with the upper end of the positioning table 9. The cardboard is clamped and positioned. Then, the rectangular frame 34 moves to the right, causing the pusher plate 35 to move upward and to the right. The stop bar 45 moves outward and downward into the positioning table 9. When the pusher plate 35 moves to the right, it can push the cardboard to the right and into the slotting machine 3. When the drive shaft 29 continues to rotate, it can cause the pusher plate 35 to move to the left and reset. The corresponding stop bar 45 moves to the upper inner side and resets. The positioning bar 28 moves to the outer side and resets. The entire working process can be repeated cyclically.

[0052] In use, when the blower head 5 is working, it can blow the cardboard in the flow bed 6 to move to one side along the inner wall of the flow bed 6, and at the same time, it can dry the cardboard. When the cardboard in the flow bed 6 reaches the positioning table 9, the positioning clamps, namely the positioning rod 28 and the drive disk 24, etc., are used. When the drive disk 24 rotates, it can drive the positioning rod 28 to move inward, thereby clamping and positioning the cardboard to avoid deviation when entering the slotting machine 3 for die cutting. This device integrates hot air drying and conveying functions, directly connecting the printing equipment and the slotting and die cutting equipment. It does not require additional independent drying devices and conveying components, realizing continuous operation of printing, drying, positioning and conveying, which greatly shortens the production cycle and effectively meets the high-efficiency requirements of large-scale production. By using hot air directional blowing to dry the printed cardboard in a targeted manner, the water-based ink can be cured quickly, avoiding problems such as ink sticking and surface scratches, and ensuring the surface of the cardboard. The stability of printing quality provides a solid foundation for subsequent slotting and die-cutting processes. Adding a clamping and positioning mechanism before the cardboard enters the die-cutting machine effectively corrects deviations caused by airflow impact and warping during cardboard transport, ensuring the cardboard enters the slotting and die-cutting equipment with a precise orientation. This significantly reduces scrap rates caused by die-cutting size deviations and inaccurate slotting positions, improving the finished product qualification rate. This device integrates drying, conveying, and positioning functions into one compact structure, minimizing space requirements and reducing equipment footprint. It also simplifies the production process, eliminating the need for separate positioning and conveying equipment, reducing equipment purchase and installation costs, and improving production cost-effectiveness. The device can adjust hot air speed, drying time, and clamping and positioning parameters according to different cardboard specifications, adapting to the processing needs of various cardboard sizes. Furthermore, the overall integration is smooth, requiring no complex manual intervention, reducing operational difficulty and improving the stability and controllability of the production process.
