Description

Technical Field

[0001] The utility model relates to printing equipment, in particular to a continuous winding mechanism of a satellite flexographic printing press. Background Art

[0002] A satellite flexographic printing press is a common printing equipment. After the printing of the base material is completed, a winding mechanism is required to wind and collect the printed base material. For a traditional winding mechanism, after the winding of one air shaft is completed, it is necessary to stop the machine to replace the air shaft and change the roll, resulting in poor smoothness of the equipment operation and affecting the overall processing efficiency of the equipment; in order to achieve continuous winding of the base material, a cutting component is usually set to cut and transfer the base material. The traditional cutting mechanism adopts a structure with upper and lower cutting knives, and the structure size of this cutting mechanism is relatively large, requiring a large layout space, resulting in a bloated internal structure of the equipment. Content of the Utility Model

[0003] In view of the deficiencies of the background art, the technical problem to be solved by the present utility model is to provide a continuous winding mechanism of a satellite flexographic printing press for solving the above problems.

[0004] To this end, the present utility model is implemented as follows:

A first card slot for pre-storing a winding air shaft is arranged on the front side of the frame near the winding rubber roller. A shaft pushing component is arranged corresponding to the first card slot. A swing frame is arranged on the rear side near the winding rubber roller. A second card slot for placing the winding air shaft is arranged on the swing frame. The swing frame is connected with a swing driving component, so that the printed product wound on the winding air shaft is tightly pressed on the winding rubber roller. It is characterized in that: rotating seats are arranged at both ends corresponding to the winding rubber roller. The rotating seats are connected with a rotation driving component.

The inflation joint is connected with an air pump. When the rotating seat rotates to the cutting angle, the first cylinder can drive the inflation joint to move and tightly press on the other end of the air hole.

[0006] The two ends of the winding rubber roller are extended with transmission shafts. A transmission sleeve is further included. The transmission sleeve is connected to the driving motor through a sprocket transmission group. The transmission sleeve is connected to the rotating seat. A rotating support ring is arranged between the transmission sleeve and the transmission shaft. The rotating support ring is composed of two semi-circular copper sleeves. The copper sleeves are connected to the transmission sleeve through fasteners.

[0007] The swing driving assembly includes a second air cylinder. The cylinder body of the second air cylinder is hinged on the frame. The piston rod of the second air cylinder is hinged to the swing frame.

[0018] As shown in the figure, the continuous winding mechanism of the satellite flexible plate printing machine disclosed by the present utility model has a frame. A winding rubber roller 9 is arranged on the frame. A first card slot 11 for pre-storing a winding air shaft 1 is arranged on the front side of the frame near the winding rubber roller 9. A push shaft assembly is arranged corresponding to the first card slot 11. Specifically, the push shaft assembly includes a push shaft block 18. The push shaft block 18 is connected to the piston rod of a fourth cylinder 21. A sliding seat 19 is arranged on the push shaft block 18. The end part of the winding air shaft 1 is partially inserted into the card cavity of the push shaft block 18, ensuring that the push shaft block 18 can push the winding air shaft 1 to be positioned and moved to the required position. A slide rail 20 cooperating with the sliding seat 19 is arranged on the frame. A swing frame 13 is arranged on the rear side near the winding rubber roller 9. A second card slot 14 for placing the winding air shaft 1 is arranged on the swing frame 13. The swing frame 13 is connected to a swing driving assembly, so that the printed product wound on the winding air shaft 1 is tightly pressed on the winding rubber roller 9. Specifically, the swing driving assembly includes a second cylinder 12. The cylinder body of the second cylinder 12 is hinged on the frame, and the piston rod of the second cylinder 12 is hinged to the swing frame 13. Rotating seats 27 are arranged at both ends corresponding to the winding rubber roller 9. The rotating seats 27 are connected to a rotating driving assembly. The rotating seats 27 have a first extension arm 26 and a second extension arm 31. A cutter holder 10 is arranged on the first extension arm 26. A rodless cylinder 22 is arranged in the cutter holder 10. A slider 25 of the rodless cylinder 22 is connected to a cutter seat 24. A cutting knife 23 is arranged on the cutter seat 24. An air hole 32 is arranged on the second extension arm 31. One end of the air hole 32 is connected to the rodless cylinder through a trachea. A first cylinder 29 is arranged on the frame. An inflation joint 30 is arranged on the piston rod of the first cylinder 29. The inflation joint 30 is connected to an air pump. When the rotating seat 27 rotates to the cutting angle, the first cylinder 29 can drive the inflation joint 30 to move and tightly press on the other end of the air hole 32.

[0019] Further, drive shafts 33 extend from both ends of the winding rubber roller 9. It also includes a transmission sleeve 35. The transmission sleeve 35 is connected to the drive motor through a sprocket transmission group 28. The transmission sleeve 35 is connected to the rotating seat 27. A rotating support ring is arranged between the transmission sleeve 35 and the drive shaft 33. The rotating support ring is composed of two semi-circular copper sleeves 34. The copper sleeves 34 are connected to the transmission sleeve 35 through fasteners. By adopting this structure, the rotation support of the transmission sleeve 35 can be realized, replacing the structure using bearings for rotation support. Since there are many transmission wheel structures at the end of the drive shaft 33, when the copper sleeve 34 wears, the fasteners between the copper sleeve 34 and the transmission sleeve 35 can be removed, and then the copper sleeve 34 can be slid inward along the drive shaft 33 out of the transmission sleeve 35, so that the copper sleeve 34 can be taken out and replaced with a new copper sleeve. It is not necessary to remove the multiple transmission wheel structures outside the drive shaft 33, effectively simplifying the replacement operation of the copper sleeve 34 for rotation support.

[0020] Further, a discharge swing arm 16 is arranged corresponding to the position where the swing frame 13 swings to the outermost end. A third card slot 15 for the winding air shaft 1 to be inserted into is arranged on the discharge swing arm 16. One end of the discharge swing arm 16 is connected to the rotating shaft 4. It also includes a third cylinder 7. The cylinder body of the third cylinder 7 is hinged on the machine frame. The piston rod of the third cylinder 7 is hinged to one end of the transmission arm 5. The other end of the transmission arm 5 is connected to the rotating shaft 4. With the above structure, when the winding air shaft 1 on the swing frame 13 finishes winding, the winding air shaft 1 will be inserted into the third card slot 15 of the discharge swing arm 16, and then the discharge swing arm 16 is controlled to swing downward to realize the unloading operation of the base material.

[0021] Further, bearings 17 are arranged at both ends of the winding air shaft 1. A guide rail part 8 matched with the bearings 17 is arranged on the machine frame. By adopting this structure, the movement guidance of the winding air shaft 1 during the winding process can be realized, improving the stability of its movement.

[0022] The working principle of the utility model is as follows: The winding air shaft 1 during winding is clamped in the second card slot 14 on the swing frame 13, and under the action of the second cylinder 12, the printed finished product is always elastically pressed between the winding rubber roller 9 and the winding air shaft 1. By controlling the rotation of the winding rubber roller 9, the printed finished product is continuously wound on the winding air shaft 1. When the finished product on the winding air shaft 1 is wound to the required amount, the push shaft block 18 pushes the pre-stored winding air shaft 1 to the required position. At this time, the glue on the winding air shaft comes into contact with the finished product during winding, causing the finished product to adhere to the winding air shaft. Meanwhile, the rotating seat 27 rotates, driving the cutter holder 10 to move to the cutting position. And at this time, the air hole 32 on the second extension arm 31 is aligned with the inflation joint 30, and the first cylinder 29 drives the inflation joint 30 to tightly press on the air hole 32. At this time, the inflation joint 30 transmits high-pressure gas through the air hole 32 and the air pipe into the rodless cylinder 22, driving the slider 25, the cutter seat 24 and the cutting knife 23 to move, cutting off the finished product during winding. Then the rotating seat 27 rotates in reverse to reset. The previously completed winding air shaft enters the third card slot 15 of the unloading swing arm 16 and moves downward for unloading under the drive of the unloading swing arm 16. The swing frame 13 swings back under the drive of the second cylinder 12. The push block 18 pushes the air shaft and it falls to the guide rail part 8. The air shaft is clamped into the second card slot 14 on the swing frame 13, and the winding operation continues.

[0023] With this structure of the utility model, by setting the rotating seat to realize the overall movement of the cutting component, the cutting component can be retracted or moved out to the cutting position. The rodless cylinder is used to drive the cutting knife to perform cutting, replacing the traditional structure of the upper and lower cutting knives cooperating for cutting, making its structure simpler, the size specification smaller, and facilitating the compact layout inside the equipment. In addition, the mobile inflation joint and the air hole are used for inflation cooperation, which can avoid the winding or drooping of the air pipe during the rotation of the rotating seat, ensuring the stability and reliability of the equipment operation.
