Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary printing equipment, in particular to a paper conveying device for printing equipment. Background Art

[0002] A printing device is a machine that processes and finishes printed sheets into printed products. When printing, the printing device uses a conveying device to continuously convey paper, uses a printing mechanism to print the conveyed paper, then uses a slitting mechanism to slit the printed paper, and finally uses a packing mechanism to pack the slit and printed paper.

[0003] At present, relatively mature technical applications have been made in paper conveying of printing equipment, mainly including using methods such as rollers or pneumatic adsorption for paper transfer, which effectively improve the automation level and production efficiency of printing equipment.

[0004] Common paper conveying devices mainly rely on the coordinated work of multiple groups of rollers to achieve the step-by-step transmission of paper. The rollers drive the paper to move along a set path through surface friction. However, in the existing roller conveying method, problems such as paper deviation and sliding are likely to occur during high-speed operation, affecting printing accuracy and the finished product rate. Summary of the Utility Model

[0005] Aiming at the disadvantages that the method of conveying paper by rollers is prone to problems such as paper deviation and sliding during high-speed operation, which affect printing accuracy and the finished product rate, the utility model provides a paper conveying device for printing equipment, and the specific technical solutions are as follows:

[0006] A paper conveying device for printing equipment includes a machine body and a conveying mechanism installed in the machine body for conveying paper. The conveying mechanism includes a number of steel conveying rollers rotatably arranged in the machine body. Anti-slip patterns for preventing the conveyed paper from slipping are provided in the middle of the outer wall of the steel conveying rollers. Two paper retaining rings for positioning the conveyed paper to prevent deviation are respectively slidably arranged on the outer walls at both ends of the steel conveying rollers.

[0007] An adjusting mechanism for adjusting the position of the paper retaining ring is arranged outside the steel conveying roller. The adjusting mechanism includes adjusting threads opened on the outer walls at both ends of the steel conveying roller, and an annular plate threadedly arranged at the adjusting threads of the steel conveying roller. The annular plate is fixedly arranged on one side of the paper retaining ring, and a fixing mechanism for further fixing the paper retaining ring is arranged on one side of the annular plate.

[0008] By adopting the above technical solutions, through the setting of the anti-slip patterns, the conveyed paper is not easy to slide on the steel conveying rollers. Through the positioning of the intermediate conveyed paper by two adjacent paper retaining rings, the paper will not be skewed during the conveying of the steel conveying rollers, indirectly improving printing accuracy and the finished product rate.

[0009] Optionally, driven gears located outside the machine body are fixedly provided on the outer walls of one ends of several of the steel conveying rollers, a transmission gear is meshed and connected between the driven gears of adjacent steel conveying rollers, a fixing frame is fixedly provided on the outer wall of the machine body, and a motor is fixedly installed in the fixing frame. A driving gear for driving the rotation of the driven gear is fixedly provided on the outer wall of the output end of the motor.

[0010] By adopting the above technical solution, through the connection of components such as the driven gear, only a single motor drive can drive several steel conveying rollers to rotate at the same speed and in the same direction, which is helpful for the conveying of paper.

[0011] Optionally, a connecting cylinder located outside the steel conveying roller is fixedly provided between the paper blocking ring and the annular plate. The fixing mechanism includes a limiting rod slidably arranged in the connecting cylinder and a magnet fixedly provided at one end of the limiting rod and magnetically attracted to the outer wall of the steel conveying roller. A pulling plate is fixedly provided at one end of the limiting rod and located outside the connecting cylinder.

[0012] By adopting the above technical solution, through the magnetic attraction of the magnet and the limitation of the limiting rod, the position of the adjusted paper blocking ring can be fixed, avoiding the loosening of the paper blocking ring and causing the paper to deviate from the positioning and shift.

[0013] Optionally, several bristles are fixedly provided in the circular groove opened at one end of the annular plate away from the connecting cylinder, and one end of the bristles is inserted and matched in the adjusting thread.

[0014] By adopting the above technical solution, the bristles can partially clean the adjusting thread when the annular plate rotates, brush away dust and other foreign matters, and prevent foreign matters such as dust from being stuck at the connection between the adjusting thread and the annular plate, thereby increasing the resistance when people rotate the annular plate.

[0015] In summary, the present utility model has at least the following beneficial effects:

[0016] 1. Through the setting of the anti-slip pattern, the conveyed paper is not easy to slide on the steel conveying roller. Through the positioning of the intermediate conveyed paper by two adjacent paper blocking rings, the paper will not be skewed during the conveying of the steel conveying roller, indirectly improving the printing accuracy and the finished product rate. Through the adjusting mechanism, the position of the paper blocking ring can be adjusted, facilitating the device to prevent deviation and position different-width papers, and having a wide application range.

[0017] 2. By rotating the annular plate outside the adjusting thread, the position of the paper blocking ring can be adjusted. Through the magnetic attraction of the magnet and the limitation of the limiting rod, the position of the adjusted paper blocking ring can be further fixed, avoiding the loosening of the paper blocking ring and causing the paper to deviate from the positioning and shift. Through the connection of components such as the driven gear, only a single motor drive can drive several steel conveying rollers to rotate at the same speed and in the same direction, which is helpful for the conveying of paper.

Detailed implementation manners

[0022] The following further elaborates on the present utility model in conjunction with the attached Figures 1 - 3 drawings.

[0023] An embodiment of the present utility model discloses a paper conveying device for a printing device. Referring to Figures 1 - 3 , it includes a machine body 1 and a conveying mechanism.

[0024] The machine body 1 can be U-shaped, capable of supporting the conveying mechanism. The conveying mechanism can convey paper into the printing device, and the printing device prints the paper.

[0025] Referring to Figures 1 - 2 , the conveying mechanism includes a plurality of steel conveying rollers 2 rotatably arranged in the machine body 1. An anti-slip pattern 21 for preventing the conveyed paper from slipping is provided in the middle of the outer wall of the steel conveying roller 2. The machine body 1 can support and limit the steel conveying roller 2. The provision of the anti-slip pattern 21 makes the conveyed paper not easy to slide on the steel conveying roller 2, improving the stability during paper conveying.

[0026] Referring to Figures 1 - 2 , two paper retaining rings 3 for positioning the conveyed paper to prevent deviation are respectively slidably arranged on the outer walls at both ends of the steel conveying roller 2. An adjusting mechanism for adjusting the position of the paper retaining ring 3 is provided outside the steel conveying roller 2. The position of the paper retaining ring 3 can be adjusted through the adjusting mechanism, facilitating the device to prevent deviation and position papers of different width dimensions.

[0028] Reference Figures 1 - 2 A fixing mechanism for further fixing the paper stop ring 3 is provided on one side of the annular plate 32. The fixing mechanism includes a limit rod 34 slidably arranged in the connecting tube 33, and a magnet 35 fixed at one end of the limit rod 34 and magnetically attracted to the outer wall of the steel conveying roller 2. The limit rod 34 can be a square rod. Under the limitation of the limit rod 34, the magnet 35 can move laterally in the connecting tube 33.

[0029] After the magnet 35 magnetically attracts the steel conveying roller 2, the position of the rear paper stop ring 3 can be further fixed by the connection between the limit rod 34 and the connecting tube 33, so as to prevent the paper stop ring 3 from loosening and causing the paper to deviate from the position.

[0030] Reference Figures 1 - 2 A pull plate 36 located outside the connecting tube 33 is fixedly provided at one end of the limit rod 34, and a plurality of bristles 37 are fixedly provided in a circular groove opened at one end of the annular plate 32 away from the connecting tube 33, and one end of the bristles 37 is inserted into the adjusting thread 31. People can pull the magnet 35 away from the steel conveying roller 2 through the pull plate 36, and rotate the limit rod 34, the connecting tube 33, the paper stop ring 3 and the annular plate 32 as a whole through the pull plate 36 to change the position of the paper stop ring 3. The bristles 37 can partially clean the adjusting thread 31 when the annular plate 32 rotates, and brush away foreign matter such as dust in the adjusting thread 31, so that foreign matter such as dust from the outside is not easily stuck at the connection between the adjusting thread 31 and the annular plate 32, thereby increasing the resistance when people rotate the annular plate 32.

[0031] Reference Figure 1 and Figure 3, on the outer walls of one ends of several steel conveying rollers 2, driven gears 22 located outside the machine body 1 are fixedly provided. A transmission gear 23 is meshed and connected between the driven gears 22 of adjacent steel conveying rollers 2. A fixing frame 11 is fixedly provided on the outer wall of the machine body 1. A motor 12 is fixedly installed in the fixing frame 11. On the outer wall of the output end of the motor 12, a driving gear 13 for driving the driven gear 22 to rotate is fixedly provided. The fixing frame 11 can support and fix the motor 12. The driving gear 13 is meshed with the driven gear 22 of the steel conveying roller 2. A rotating rod is fixedly provided in the transmission gear 23, and one end of the rotating rod is rotatably connected to the outer wall of the machine body 1.

[0032] After the motor 12 rotates, it will drive the driving gear 13 to rotate. After the driving gear 13 rotates, it will drive the driven gear 22 of the steel conveying roller 2 to rotate, thereby rotating the steel conveying roller 2. The driven gears 22 between adjacent steel conveying rollers 2 will be meshed and connected through the transmission gear 23, so that when a certain steel conveying roller 2 rotates, it will drive other steel conveying rollers 2 to rotate synchronously, at the same speed and in the same direction, so as to stably convey the paper.

[0033] The implementation principle of a paper conveying device for a printing device according to an embodiment of the present utility model is as follows:

[0034] During use, the user can pull and rotate the pull plate 36 outward from the connecting cylinder 33 according to the width dimension of the paper to be conveyed, so as to rotate the annular plate 32 outside the steel conveying roller 2. With the threaded connection of the adjusting thread 31, it can drive the paper blocking ring 3 to move on the steel conveying roller 2, so as to adjust the position of the paper blocking ring 3, so that adjacent two paper blocking rings 3 can block and position the edge of the paper conveyed between the steel conveying rollers 2, so that the paper will not be deflected during the conveyance of the steel conveying roller 2;

[0035] Then people can push the pull plate 36 inward to the connecting cylinder 33. With the connection of the limiting rod 34, after the magnet 35 moves, it will magnetically attract the steel conveying roller 2 to further fix the position of the adjusted paper blocking ring 3, and prevent the paper blocking ring 3 from loosening and causing the paper to deviate from the positioning.

[0036] Then people start the motor 12. After the motor 12 rotates, it will drive the driving gear 13 to rotate. With the meshing of components such as the driven gear 22 and the transmission gear 23, it can drive the steel conveying rollers 2 to rotate synchronously, at the same speed and in the same direction. With the anti-slip effect of the anti-slip pattern 21, it can stably convey the paper.
