Description

Technical Field

[0001] This utility model relates to the field of printing auxiliary technology, and in particular to an auxiliary limiting device for a digital printing machine. Background Technology

[0002] Digital printing presses are widely used in modern office and commercial printing; during the printing process, the printed paper is continuously output through the paper outlet.

[0003] A search revealed Chinese patent CN219883552U, which discloses an auxiliary limiting device for a digital printing machine. The device includes a printing device body with a printing outlet on one side. Fixed blocks are fixedly connected to both ends of the printing device body, and a sliding rod is fixedly connected to one end of each fixed block. This device, by adding an outlet limiting component, can limit and hold the printed paper material, facilitating the operator's sorting and binding, and effectively preventing the paper material from becoming messy and affecting subsequent use.

[0004] However, the device still has the following problems. When the device is in use, the printed paper falls on the top of the placement plate. Then, the staff manually adjusts the distance between the movable limit block and the fixed limit block to make the paper neatly arranged. However, in actual use, the paper output position of the printing press is prone to deviation, which requires the staff to frequently adjust the position of the movable limit block, resulting in a heavy workload and making it difficult to effectively improve the convenience of using the device. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an auxiliary limiting device for digital printing machines.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An auxiliary limiting device for a digital printing machine includes a printing machine body, a paper outlet is provided on one side of the outer wall of the printing machine body, and a sorting component and a driving component are provided at one end of the printing machine body.

[0007] The sorting component includes a paper tray fixedly connected to the printing press body near the paper outlet. A baffle is fixedly connected to one end of the paper tray. A pair of sorting plates are slidably connected to the top two sides of the paper tray. A pair of guide plates are fixedly connected to the bottom of each sorting plate. Two pairs of guide grooves adapted to the guide plates are opened on the bottom two sides of the paper tray, and the outer wall of the guide plate is slidably connected to the inner wall of the guide groove. A pair of rotating shafts are rotatably connected to the outer wall of the printing press body near the paperboard. A pair of cams are fixedly connected to both ends of the outer peripheral wall of each rotating shaft. A pair of side plates are fixedly connected to both sides of the outer wall of the paperboard. A connecting rod is slidably connected to one end of each side plate, and one end of each connecting rod is fixedly connected to one end of an adjacent guide plate. A spring is sleeved between the outer peripheral wall of each connecting rod and the outer wall of the guide plate. By setting a sorting component driven by a drive assembly, the periodic rotation of the cams pushes the sorting plate to reciprocate through the connecting rods and springs. This continuously and automatically pushes the paper output from the paper outlet to one side of the baffle and sorts it neatly without manual intervention, significantly improving the neatness of the paper output and work efficiency.

[0008] Preferably, each of the guide grooves has rolling grooves on both sides of its inner wall, and each of the guide plates has rolling balls that are adapted to the rolling grooves on both sides of its outer wall. Through the cooperation of the rolling balls and the rolling grooves, the sliding friction between the guide plate and the guide groove is transformed into rolling friction, which greatly reduces the frictional resistance and wear of the finishing plate during the movement process.

[0009] Preferably, the drive assembly includes a support plate fixedly connected to the outer wall of the printing press body away from the paperboard, and a pair of fixing brackets are fixedly connected to one side of the top of the support plate.

[0010] Preferably, one end of each pair of fixed brackets is rotatably connected to a drive shaft, and a pair of bevel gears are fixedly connected to both ends of the drive shaft.

[0011] Preferably, one end of each of the rotating shafts is fixedly connected to a bevel gear, and each bevel gear meshes with an adjacent bevel gear.

[0012] Preferably, a motor is fixedly connected to the top of the support plate near the fixed frame, and a belt is fitted together between the output shaft of the motor and one end of the outer peripheral wall of the transmission shaft to form a transmission connection.

[0013] The beneficial effects of this utility model are as follows: 1. The rotating shaft drives the cam to rotate, and the cam rotates to abut against the guide plate. The guide plate then drives a pair of sorting plates to move away from each other synchronously. The cam continues to rotate, and through the cooperation of the spring, connecting rod and side plate, the guide plate is reset, so that the pair of sorting plates move closer to each other synchronously. This achieves the reciprocating movement of the pair of sorting plates away from each other, which facilitates the sorting of the paper piled on top of the paperboard, keeps the paper clean, facilitates subsequent work, and effectively improves the convenience of using the device. 2. The motor and belt work together to drive the transmission shaft to rotate. Then, the transmission shaft works with bevel gear 2 and bevel gear 1 to drive a pair of rotating shafts to rotate synchronously in opposite directions, further improving the ease of use of the device.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Example 1, referring to Figure 1-4 An auxiliary limiting device for a digital printing machine includes a printing machine body 1, wherein the printing machine body 1 is a Lenovo Xiaoxin P7525HD color printing machine, and a paper outlet 2 is provided on one side of the outer wall of the printing machine body 1. It also includes a sorting component and a driving component provided at one end of the printing machine body 1.

[0018] like Figures 1-3As shown, in one embodiment, the sorting assembly includes a paper tray 3 fixedly connected to the printing press body 1 near the paper outlet 2 via a connecting rod. A baffle 4 is fixedly connected to one end of the paper tray 3. A pair of sorting plates 5 are slidably connected to the top two sides of the paper tray 3. A pair of guide plates 7 are bolted to the bottom of each sorting plate 5. Two pairs of guide grooves 8, adapted to the guide plates 7, are provided on both sides of the bottom of the paper tray 3. The outer wall of the guide plate 7 is slidably connected to the inner wall of the guide groove 8. The mutual cooperation between the guide plates 7 and the guide grooves 8 improves the stability of the sorting plate 5's movement. A pair of rotating shafts 14 are rotatably connected to the outer wall of the printing press body 1 near the paper tray 3. A pair of cams 15 are fixedly connected to both ends of the outer peripheral wall of each rotating shaft 14. The cams 15 press the guide plates 7, thereby... The paper sorting plate 5 is driven to slide back and forth to sort the paper. A pair of side plates 9 are fixedly connected to both sides of the outer wall of the paperboard 3. A connecting rod 10 is slidably connected to one end of each side plate 9, and one end of each connecting rod 10 is fixedly connected to one end of the adjacent guide plate 7. A spring 11 is sleeved between the outer peripheral wall of each connecting rod 10 and the outer wall of the guide plate 7. Through the mutual cooperation between the spring 11, the connecting rod 10 and the side plate 9, the guide plate 7 is driven to reset. Rolling grooves 12 are opened on both sides of the inner wall of each guide groove 8. Roller balls 13 that are adapted to the rolling grooves 12 are slidably connected to both sides of the outer wall of each guide plate 7. Through the mutual cooperation between the rolling grooves 12 and the roller balls 13, the sliding friction between the guide plate 7 and the guide groove 8 is converted into rolling friction, which improves the smoothness of the movement of the sorting plate 5 and reduces the frictional wear between the parts of the device.

[0019] like Figure 1 and Figure 4 As shown, in one embodiment, the driving assembly includes a support plate 6 fixedly connected to the outer wall of the printing machine body 1 away from the paperboard 3. A pair of fixed brackets 17 are fixedly connected to one side of the top of the support plate 6. One end of the pair of fixed brackets 17 is rotatably connected to a drive shaft 18. A pair of bevel gears 19 are fixedly connected to both ends of the drive shaft 18. One end of each rotating shaft 14 is fixedly connected to a bevel gear 16, and each bevel gear 16 meshes with the adjacent bevel gear 19. A motor 20 is fixedly connected to the top of the support plate 6 near the fixed brackets 17. A belt 21 is fitted between the output shaft of the motor 20 and one end of the outer peripheral wall of the drive shaft 18 to form a transmission connection. Through the mutual cooperation between the motor 20 and the belt 21, the drive shaft 18 is driven to rotate.

[0020] Working principle: During use, the paper printed by the printing press body 1 falls onto the paper tray 3 through the paper outlet 2. Then, the motor 20 is started. Through the interaction between the motor 20 and the belt 21, the transmission shaft 18 is driven to rotate. Then, through the interaction between the transmission shaft 18 and the bevel gear 19 and bevel gear 16, a pair of rotating shafts 14 are driven to rotate synchronously in opposite directions. Then, the rotating shafts 14 drive the cam 15 to rotate. Then, the cam 15 rotates and abuts against the guide plate 7. Then, the guide plate 7 drives a pair of sorting plates 5 to move away from each other synchronously. At the same time, the guide plate 7 drives the connecting rod 10 to move outward of the side plate 9 to compress the spring 11. Then, the cam 15 continues to rotate. Through the interaction between the spring 11, the connecting rod 10 and the side plate 9, the guide plate 7 is driven to reset, so that the pair of sorting plates 5 move closer to each other synchronously. This realizes the reciprocating movement of the pair of sorting plates 5 away and closer, which facilitates the sorting of the paper piled on top of the paper tray 3, keeps the paper clean, facilitates subsequent work, and effectively improves the convenience of using the device.
