Description

Technical Field

[0001] The invention relates to a paper loading device, in particular to a paper loading device for a composite printing press. Background Art

[0002] During the use of the composite printing machine, it is necessary to first place the rolled base paper in the unwinding unit of the composite printing unit, then pull out one end of the base paper and insert it into the printing unit for printing, and then print through the rotation of the unwinding unit and the operation of the printing unit.

[0003] First, in the existing method of transporting rolled base paper, it is usually manually transported directly to the unwinding unit of the composite printing machine, which is more labor-intensive to operate. There is also a unwinding device of a coating machine as shown in the authorized patent publication number CN212863331U. Its coating cloth structure is similar to that of rolled base paper and can also replace the base paper as a whole. However, when transporting it, the whole roll of base paper must be placed on the base first, and then the air expansion shaft is inserted into the base, and then the base paper is supported by the downward movement of the connecting seat and the air expansion shaft, and then the base paper is lifted. However, when transporting, the above patent needs to transport the base paper to the base first, and the base paper is easily rubbed with the base, causing wear on the outer surface of the base paper, and the worn base paper usually needs to be removed, which easily causes waste of base paper.

[0004] Secondly, in the existing method, when pulling out the base paper and feeding it into the printing unit, one end of the base paper is usually pulled out manually and fed into the printing unit. When the base paper is pulled into the printing unit from the paper loading position, the ends of the base paper are usually gathered together to facilitate the movement of the base paper, which can also facilitate the base paper to be inserted into the printing unit. However, the gathered base paper is difficult to print as the leading base paper, and in the subsequent transportation process, the rest of the base paper will also be affected by the front end and wrinkled, which will affect the printing of the base paper and easily cause waste of base paper. Summary of the invention

[0005] In view of this, the present invention provides a paper loading device for a composite printing press capable of reducing the waste of base paper.

DETAILED DESCRIPTION

[0026] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments, but is not intended to limit the present invention. Example

[0027] A paper loading device for a composite printing press, such as Figure 1-Figure 4As shown, it includes a bottom plate 1, a guide seat 2, a base paper clamping mechanism 3, a first side upright plate 4, a second side upright plate 41, a bonding roller 5, a stripping rod 51, a driving assembly 6, a supporting roller 7, and a placing assembly 8. A guide seat 2 is arranged in the middle of the top of the bottom plate 1, and the base paper clamping mechanism 3 is arranged on the guide seat 2 for clamping the base paper. The first side upright plate 4 and the second side upright plate 41 are bolted to the left side of the top of the bottom plate 1. The first side upright plate 4 and the second side upright plate 41 are symmetrically arranged front to back. A track guide groove in a waist-shaped shape is opened on the front side of the first side upright plate 4. A driving assembly 6 is arranged on the second side upright plate 41. An bonding roller 5 is arranged between the driving assembly 6 and the track guide groove. The outer side of the bonding roller 5 has a bonding The adhesive roller 5 has a plurality of support rollers 7 connected to the first side plate 4 and the second side plate 41, and the support rollers 7 are located in the track guide groove. A placement component 8 is provided on the top right side of the bottom plate 1 for placing rolled base paper.

[0028] like Figure 2-Figure 3 As shown, the base paper clamping mechanism 3 includes a sliding seat 31, a clamping arm 32, a hydraulic cylinder 33, a clamping cylinder 34, a control panel 35 and a driving rotation component. The front and rear sides of the guide seat 2 are slidably connected to the sliding seat 31, the clamping arm 32 is rotatably connected to the sliding seat 31, the middle part of the clamping arm 32 is rotatably connected to the hydraulic cylinder 33, the piston rod of the hydraulic cylinder 33 is rotatably connected to the sliding seat 31, two clamping cylinders 34 are installed on the right side of the bottom plate 1, the two clamping cylinders 34 are both located between the two sliding seats 31, and the telescopic rods of the two clamping cylinders 34 are respectively connected to the sides of the two sliding seats 31 that are close to each other, a control panel 35 is installed on the top of the front clamping arm 32, and a driving clamping component is provided on the clamping arm 32, which can clamp the base paper and drive the base paper to rotate, and the two clamping cylinders 34 and the two hydraulic cylinders 33 are electrically connected to the control panel 35.

[0029] like Figure 2-Figure 3 As shown, the driving rotation assembly includes a servo motor 361 and a supporting shaft 362 . The servo motor 361 is installed on the right side of the clamping arm 32 , and the supporting shaft 362 is connected to the output shaft of the servo motor 361 .

[0030] like Figure 4 and Figure 5As shown, the driving assembly 6 includes a driving motor 61 and a belt transmission group 62. The driving motor 61 is installed at the lower part of the second side vertical plate 41, and the belt transmission group 62 is arranged on the second side vertical plate 41. The output shaft of the driving motor 61 is connected to the transmission shaft on the lower side of the belt transmission group 62, so that the operation of the driving motor 61 can drive the belt transmission group 62 to run, and the adhesion roller 5 is connected to the belt transmission group 62, so that the operation of the belt transmission group 62 can drive the adhesion roller 5 to move along the track guide groove.

[0031] like Figure 4 As shown, the placement component 8 includes a placement rail 81 and a placement seat 82. The placement rail 81 is connected to the right side of the top of the bottom plate 1, and the placement seat 82 is slidably connected to the top of the placement rail 81. The placement seat 82 is used to place the roll of base paper. After the roll of base paper is placed on the placement seat 82, the distance between the center position of the roll of base paper and the top of the placement rail 81 is greater than the radius of the roll of base paper to prevent the roll of base paper from being worn due to friction between the roll of base paper and the placement rail 81.

[0032] When it is necessary to feed paper to the composite printing unit, the device can be used. Before use, the device needs to be moved to the feed end of the printing unit in the composite printing unit, and the feed end of the printing unit is located above the first side vertical plate 4 and the second side vertical plate 41. Initially, the piston rod of the hydraulic cylinder 33 and the telescopic rod of the clamping cylinder 34 are both in an extended state. When in use, the rolled base paper is first moved to the placement seat 82. After placement, the placement seat 82 is pushed to move leftward along the placement track 81 until the rolled base paper on the placement track 81 is located at the moving track of the support shaft 362. At this time, the piston rod of the hydraulic cylinder 33 can be controlled to retract. When the piston rod of the hydraulic cylinder 33 is retracted, due to the hydraulic cylinder 33, the sliding seat 31 and the clamping arm 32 are all rotatable connections, which can make the clamping arm 32 rotate. The rotation of the clamping arm 32 can drive the supporting shaft 362 to rotate. After the supporting shaft 362 rotates, it is aligned with the front and rear sides of the center position of the base paper. At this time, the clamping cylinder 34 can be started to retract the telescopic rod to drive the sliding seats 31 on both sides to approach each other, thereby driving the supporting shafts 362 on both sides to approach each other. After the supporting shafts 362 on both sides are close to each other, they can extend into the tube at the center position of the base paper, thereby clamping the base paper. At this time, the piston rod of the hydraulic cylinder 33 can be started again to extend to drive the clamping arm 32 to reset, lift the base paper, and then pull one end of the base paper out and move it under the adhesion roller 5. When pulling it out, the base paper needs to be pulled out neatly and the end of the base paper emerges from the adhesion roller 5, and then the base paper The adhesion roller 5 is adhered to the adhesion roller 5, and then the driving motor 61 is started to drive the belt transmission group 62 to run, thereby driving the adhesion roller 5 to move clockwise along the track guide groove. When moving, the adhesion roller 5 can drive the base paper to move together, and the base paper will bypass the support roller 7. When the adhesion roller 5 moves to the top of the track guide groove, the end of the base paper that emerges from the adhesion roller 5 can also extend into the feed end of the printing unit, and the base paper also contacts the stripping rod 51. At this time, the adhesion roller 5 continues to move. Since the base paper is limited by the stripping rod 51, the adhesion roller 5 can be separated from the base paper. At this time, the driving motor 61 is turned off, so that the adhesion roller 5 is located above the track guide groove. At the same time, the printing unit also moves with the base paper for printing. When the printing unit is started, the servo motor 361 is started to drive The support shaft 362 rotates to release the base paper, so that the device can be used to load paper on the composite printing machine, and when loading paper, the rolled base paper can be placed on the placement seat 82 first, and then the movement of the placement seat 82 can drive the movement of the rolled base paper to transport the rolled base paper. In this process, since the distance between the center position of the base paper after it is placed on the placement seat 82 and the paper release track is greater than the radius of the rolled base paper, the contact and wear between the rolled base paper and the placement track 81 can be avoided, thereby avoiding the waste caused by the removal of the worn base paper; the base paper can also be neatly fed into the printing unit through the adhesive roller 5, without the need to gather the base paper into a ball for feeding, which can avoid the wrinkles of the base paper and also reduce the waste of base paper.

[0033] During actual use, a control program can be input on the control panel 35 so that the control panel 35 controls the operation of the clamping cylinder 34 and the hydraulic cylinder 33. A control program can also be input so that the control panel 35 controls the clamping cylinder 34 and the hydraulic cylinder 33 on both sides respectively, making the control more flexible. Example

[0034] On the basis of Example 1, Figure 1 , Figure 6 , Figure 7 and Figure 8 As shown, it also includes a tensioning mechanism 9, which includes a connecting plate 91, a tensioning cylinder 92 and a tensioning roller 93. The first side vertical plate 4 and the left side of the second side vertical plate 41 are both slidably connected to the connecting plate 91, and tensioning rollers 93 are evenly spaced and connected to the connecting plate 91. The number of tensioning rollers 93 is consistent with the number of rollers 7, and the tensioning rollers 93 and the rollers 7 are staggered. The first side vertical plate 4 and the second side vertical plate 41 are both installed with tensioning cylinders 92, and the telescopic rod of the tensioning cylinder 92 is connected to the connecting plate 91, so that the tensioning cylinder 92 can drive the tensioning roller 93 to move through the connecting plate 91, and the movement of the tensioning roller 93 can squeeze the base paper to make the base paper tight.

[0035] Initially, the telescopic rod of the tensioning cylinder 92 is in an extended state. After the base paper is fed into the printing unit, the telescopic rod of the tensioning cylinder 92 can be started to retract and drive the connecting plate 91 to move to the right. When the connecting plate 91 moves to the right, it can drive the tensioning roller 93 to move to the right. The movement of the tensioning roller 93 to the right can squeeze the base paper and move the base paper, so that the base paper is repeatedly bent along the tensioning roller 93 and the supporting roller 7, making the base paper more tensioned, thereby preventing the base paper from shrinking and wrinkling during transportation, thereby affecting printing.

[0036] like Figure 1 and Figure 6 As shown, a supporting roller 10 is also included, and the supporting roller 10 is connected between the right sides of the first side upright plate 4 and the second side upright plate 41.

[0037] When the base paper is pulled out, the support roller 10 can support the base paper to provide support for the base paper, thereby preventing the base paper from shaking and wrinkling during transportation due to lack of support over a long distance, thereby affecting printing.

[0038] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
