Description
Technical Field
[0001] The invention relates to the technical field of rotary printing, and in particular to a positioning device for rotary glue spray printing. Background Art
[0002] The rotary press is a highly efficient printing equipment, widely used in large-scale printing production. It uses a roller to continuously rotate and die-cut, and is one of the most efficient die-cutting machines. The characteristics of the rotary press include the use of roll paper, high printing speed, simultaneous printing on both sides, and suitability for printed products with large print runs and short delivery times. The rotary press's glue spraying printing method is an advanced printing technology that uses inkjet technology to evenly spray glue on the printing material to achieve efficient and accurate printing.
[0003] When inkjet printing is performed on roll paper, the paper on the roll paper is transported through the positioning device by the feeding device, and then the paper enters the printing device for inkjet printing. Since roll paper is used, unlike cut paper, the roll paper is continuous paper and cannot be straightened by simply pushing it. Therefore, it is very important to check whether the roll paper is loose and whether the paper is aligned with the printing device during the transportation of the roll paper. After detecting that the position of the roll paper is offset during the movement of the paper, the traditional positioning device will drive the paper back to the aligned position by the translation of the positioning device. However, when the paper deviates again, since the paper cannot slide on the positioning device, the translation distance of the positioning device may be too far to be corrected again. At the same time, when the paper deviates on the positioning device, the two sides of the paper contact the two sides of the positioning device, which may cause the edge of the paper to be damaged and broken. Therefore, in order to correct and position various offset situations of the paper, we propose a positioning device for rotary press inkjet printing. Summary of the invention

The sleeve shafts on both sides of each pushing wheel are respectively rotatably provided on the two ends of the pushing frame. The multiple pushing wheels are staggered, and the multi-section driving cylinder is provided with a plurality of equidistant telescopic sliding output ends. The multiple pushing frames are respectively connected to the multi-section output ends on the multi-section driving cylinder, and the multiple pushing frames do not contact each other.
[0010] The paper support mechanism also includes a support wheel, a second motor and a sliding support assembly. The support wheel is rotatably arranged on the flip frame.

[0011] The sliding support assembly includes a sliding cylinder, a triangular groove, a rotating sleeve and a hollow through hole. The sliding cylinder is rotatably set on the flip frame.

The sliding block 2 is larger than the sliding block 1, and the sliding block 1 is slidably set in the triangular groove close to the hollow through hole.
[0012] The working principle and beneficial effects of the present invention are: 1. In the present invention, a plurality of driving cylinders and driving wheels are provided, and the plurality of driving wheels are provided in a stepped shape. When the driving wheels slide under the drive of the plurality of driving cylinders, the distances between all the driving wheels change in the same manner, and the driving wheels drive the paper to move. Since the plurality of driving wheels are in a stepped shape and the driving wheels are not staggered, the paper is prevented from being clamped in the gaps between the driving wheels when the driving wheels drive the paper to move. At the same time, when the plurality of driving wheels are pulled by the multi-section driving cylinder to change the spacing, the driving cylinder pulls the displacement base to slide, and the plurality of driving wheels are translated at the same time, and the paper is pulled to deflect accordingly. The distances between the plurality of driving wheels are expanded or contracted when in contact with the paper, and the plurality of driving wheels smooth out the wrinkles that may exist on the paper when passing through the paper, so as to avoid the wrinkles that may exist after the paper deflection affecting the subsequent printing. 2. In the present invention, by setting the sliding block 1 and the sliding block 2, the paper drives the rotating sleeve to rotate, and the sliding block 1 and the sliding block 2 on the rotating sleeve will contact the straight edge of the triangular groove to push the sliding cylinder to rotate. At the same time, when the paper is corrected and moves horizontally, the paper drives the rotating sleeve to slide on the sliding cylinder. At this time, the sliding block 1 and the sliding block 2 are in contact with the straight edge of the triangular groove, and the rotating sleeve can slide. When the correction of the paper is completed, the sliding cylinder is driven by the output end of the motor 2 to rotate to the side that is not in contact with the paper. At this time, the hollow through hole on the sliding cylinder is closed under the action of gravity. When the sliding block rotates to the upper side of the sliding cylinder, since the sliding block 2 is larger than the sliding block 1, the sliding block 2 is heavier than the sliding block 1. Under the weight of the sliding block 2, the rotating sleeve rotates on the sliding cylinder. The sliding block 2 moves downward in the triangular groove, and the sliding block 1 moves upward in the triangular groove. Both the sliding block 1 and the sliding block 2 are in contact with the inclined edge of the triangular groove. Under the action of gravity, the rotating sleeve continues to rotate, the sliding block 1 continues to slide upward, and the sliding block 2 continues to slide downward, so that the rotating sleeve slides toward the center of the sliding sleeve, and the rotating sleeve is automatically reset for the next use. 3. In the present invention, by setting up a paper support mechanism, the paper can be pulled to move horizontally, and the wrinkles on the paper can be smoothed by the equal-spaced movement of multiple push wheels. By setting up a correction mechanism, the paper can be supported during the paper correction process and can move and reset with the paper. BRIEF DESCRIPTION OF THE DRAWINGS

The drive assembly and the multi-section drive cylinder 5 are arranged on the displacement platform 10. When the positioning electric eye 2 detects that the position of the paper is offset, the output end of the drive cylinder 9 extends to push the displacement platform 10 to rise, so that the push wheel 17 contacts the paper. At this time, the paper can be driven to move by the push wheel 17. While the push assembly drives the paper to move, the output end of the drive cylinder 8 drives the displacement base 7 to move horizontally, which can also drive the paper to deviate. The contact and separation of the push wheel 17 and the paper are controlled by the drive cylinder 9, so that the displacement base 7 can be moved repeatedly to correct the paper in the same direction for multiple times.
[0019] like Figure 2~Figure 4 As shown, the driving assembly includes a motor 11, a driving wheel 12, a clamping wheel 13, a tensioning wheel 14, a transmission belt 15 and a square rod 16. The motor 11 is fixedly arranged on the displacement platform 10.

A clamping wheel 13 is provided on both sides of each driving wheel 12. A plurality of tensioning wheels 14 are provided, and the plurality of tensioning wheels 14 are rotatably arranged on the displacement platform 10. The transmission belt 15 is provided with a plurality of tensioning wheels 14. The tensioning sleeve is arranged on the driving wheel 12, the pressing wheel 13 and the tensioning wheel 14. A square rod 16 is fixedly arranged on each driving wheel 12. The driving wheel 12, the pressing wheel 13 and the tensioning wheel 14 in this embodiment are preferably gears, and the transmission belt 15 is preferably a chain. When the output end of the motor 11 drives the driving wheel 12 to rotate, the driving wheel 12 drives all the driving wheels 12 to rotate in the same direction and at the same speed through the chain. The square rod 16 is set as a hexagonal rod. When the driving wheel 12 rotates, it can drive all the square rods 16 to rotate at a uniform speed. Through the uniform rotation of the square rods 16, all the driving wheels 17 can be driven to rotate.
[0020] like Figure 5~Figure 7As shown, the pushing component includes a pushing wheel 17, a sleeve shaft 18 and a pushing frame 19, a plurality of pushing wheels 17 are provided, a pushing wheel 17 is slidably provided on each square rod 16, a plurality of sleeve shafts 18 are provided, the sleeve shaft 18 is slidably provided on the square rod 16, a sleeve shaft 18 is provided on both sides of each pushing wheel 17, a plurality of pushing frames 19 are provided, the pushing frames 19 correspond to the pushing wheels 17 one by one, the sleeve shafts 18 on both sides of each pushing wheel 17 are rotatably provided on the two ends of the pushing frame 19, the plurality of pushing wheels 17 are staggered, the multi-section driving cylinder 5 is provided with a plurality of equidistant telescopic sliding output ends, the plurality of pushing frames 19 are respectively connected to the multi-section output ends on the multi-section driving cylinder 5, the plurality of pushing frames 19 do not contact each other, all the pushing wheels 17 rotate at the same speed as the square rod 16, and the plurality of pushing wheels 17 are provided with a plurality of sleeve shafts 18 on both sides of the pushing wheel 17. The plurality of push wheels 17 are arranged in a stepped shape. When the push wheel 17 slides under the drive of the multi-section driving cylinder 5, the distance between all the push wheels 17 changes in the same way. The push wheels 17 drive the paper to move. Because the plurality of push wheels 17 are in a stepped shape and the push wheels 17 are not staggered, the paper is prevented from being clamped in the gap between the push wheels 17 when the push wheels 17 push the paper to move. At the same time, while the multi-section driving cylinder 5 pulls the changing spacing of the plurality of push wheels 17, the driving cylinder 8 pulls the displacement base 7 to slide, and the plurality of push wheels 17 then translate at the same time, pulling the paper to deflect accordingly. The distance between the plurality of push wheels 17 opens or contracts when in contact with the paper. When the plurality of push wheels 17 pass through the paper, the wrinkles that may exist on the paper will be smoothed to avoid the wrinkles that may exist after the paper is deflected and affect the subsequent printing.
[0021] like Figure 5~Figure 7 As shown, the paper support mechanism also includes a support wheel 20, a second motor 21 and a sliding support assembly. The support wheel 20 is rotatably arranged on the flip frame 4, the second motor 21 is fixedly installed on the positioning platform 3, the output end of the second motor 21 is connected to the flip frame 4, and the sliding support assembly is rotatably arranged on the flip frame 4 on a side away from the support wheel 20. The sliding support assembly is used to support the paper when positioning and correcting the paper. When positioning and correcting the paper are not performed, the support wheel 20 supports the paper. When the push wheel 17 contacts the paper under the action of the driving cylinder 9, the output end of the second motor 21 rotates with the flip frame 4 so that the rotating sleeve 24 contacts the paper.
[0022] like Figure 5~Figure 7As shown, the sliding support assembly includes a sliding cylinder 22, a triangular groove 23, a rotating sleeve 24 and a hollow through hole 25. The sliding cylinder 22 is rotatably arranged on the flip frame 4. Two triangular grooves 23 are provided. The two triangular grooves 23 are circumferentially opened on the sliding cylinder 22. A plurality of rotating sleeves 24 are provided. The rotating sleeve 24 is arranged on the sliding cylinder 22. The hollow through hole 25 is opened on the sliding cylinder 22. The rotating sleeve 24 is provided with a sliding block 1 26 and a sliding block 2 27. The sliding block 1 26 is slidably arranged therein. In one triangular groove 23, a second sliding block 27 is arranged in another triangular groove 23, the second sliding block 27 is larger than the first sliding block 26, and the first sliding block 26 is slidably arranged in the triangular groove 23 near the hollow through hole 25. When the flip frame 4 rotates, the paper drives the rotating sleeve 24 to rotate, and the sliding block 1 26 and the second sliding block 27 on the rotating sleeve 24 will contact the straight edge of the triangular groove 23 to push the sliding cylinder 22 to rotate. At the same time, when the paper is corrected and moves horizontally, the paper drives the rotating sleeve 24 in the sliding cylinder 22. The sliding block 1 26 and the sliding block 27 are both in contact with the straight edge of the triangular groove 23 at this time, and the rotating sleeve 24 can slide. When the paper is corrected, the sliding cylinder 22 is driven by the output end of the motor 21 to rotate to the side that is not in contact with the paper. At this time, the hollow through hole 25 on the sliding cylinder 22 rotates to the upper side of the sliding cylinder 22 under the action of gravity. Since the sliding block 27 is larger than the sliding block 1 26, the sliding block 27 is heavier than the sliding block 1 26. Under the weight of the sliding block 27, the sliding block 27 The lower rotating sleeve 24 rotates on the sliding cylinder 22, the sliding block 27 moves downward in the triangular groove 23, and the sliding block 1 26 moves upward in the triangular groove 23. The sliding block 1 26 and the sliding block 27 are both in contact with the inclined edge of the triangular groove 23. Under the action of gravity, the rotating sleeve 24 continues to rotate, the sliding block 1 26 continues to slide upward, and the sliding block 27 continues to slide downward, so that the rotating sleeve 24 will slide toward the center of the sliding sleeve, and the rotating sleeve 24 will automatically reset for the next use.
[0023] In summary, the working principle of the positioning device of the rotary press glue printing is as follows: the positioning electric eye 2 detects that the paper is offset, at this time the motor 21 drives the flip frame 4 to rotate, so that the rotating sleeve 24 contacts the paper, and the output end of the driving cylinder 29 drives the displacement platform 10 to rise, so that the driving wheel 17 contacts the paper, at this time the output end of the motor 11 drives the driving wheel 12 and the transmission belt 15 to rotate, the square rod 16 drives the driving wheel 17 to rotate, at this time the output end of the driving cylinder 18 pulls the displacement base 7 and the displacement platform 10 to translate, and the multi-section output end of the multi-section driving cylinder 5 drives the displacement base 7 and the displacement platform 10 to translate. The output end drives the push wheel 17 to slide on the square rod 16 through the push frame 19, and the sleeve shaft 18 rotates on the push frame 19. When the paper deviates, the rotating sleeve 24 is driven to slide on the sliding cylinder 22. When the paper deviation correction is completed, the output end of the motor 21 drives the flip frame 4 to rotate so that the rotating sleeve 24 does not contact the paper. At this time, the sliding cylinder 22 rotates to the hollow channel at the top, and the sliding block 1 26 and the sliding block 2 27 on the rotating sleeve 24 move upward and downward in the triangular groove 23 respectively, so that the rotating sleeve 24 moves toward the center of the sliding cylinder 22 and resets.
