Description

Technical Field

[0001] This invention relates to the field of printing equipment, and in particular to a transport device for printing publications. Background Technology

[0002] Corrugated cardboard is a common material used in cartons. Printing is typically done on the cardboard to ensure the cartons' aesthetic appeal. During printing, the corrugated cardboard is fed into the offset printing press via a conveyor line. Because cartons are relatively light, there is little friction between the carton and the feed rollers of the conveyor line, making it prone to misalignment and causing the printed pattern on the corrugated cardboard to shift.

[0003] Existing technology application CN201520207971.3 discloses a pressing device on a carton printing and transport line, including a fixing module and a pressing module. The fixing module comprises a support arm and a crossbar. The support arm is bolted to the frame on both sides of the printing and transport line, and the crossbar is positioned between the two support arms. The pressing module is mounted on the crossbar and includes a pressing wheel and a pressing strip. The crossbar, perpendicular to the transport direction in the horizontal plane, sequentially comprises a pressing strip, a pressing wheel, a pressing wheel, and a pressing strip. The pressing wheel is mounted on the crossbar via a bracket. The pressing strip is connected to the crossbar via a connecting ring, and a pad is provided at the pressing position of the pressing strip. This utility model provides a pressing device on a carton printing and transport line, which can prevent the carton from shifting during the printing and transport process. However, the device has defects in actual use: the device uses the pressure rollers 3 and pressure strips 4 to press and roll the carton, but does not limit and guide the material on the side of the carton, so the carton may still shift during transportation. Moreover, when adjusting the pressure rollers 3 according to the size of the carton, the adjustment position of each pressure roller 3 needs to be adjusted individually, which is inconvenient to operate. Summary of the Invention

[0004] The purpose of this invention is to provide a transport device for printing publications to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a transport device for printing publications, comprising a material conveying base, wherein multiple guide rollers are arranged in the material conveying base, and each guide roller is provided with a paperboard guiding and positioning device. The guiding and positioning device includes guiding and positioning components arranged on both sides of the guide roller. The guiding and positioning components include a sliding sleeve slidably connected to the guide roller, wherein a ball is embedded inside the sliding sleeve and the ball rolls in contact with the outer wall of the guide roller. A side pressure roller bracket bent inward is welded to one side of the outer wall of the sliding sleeve, and the end of the side pressure roller bracket... A side pressure roller is connected to the sliding sleeve, and a top pressure roller support extending obliquely upward is welded on the sliding sleeve. The upper inner side of the top pressure roller support is connected to the middle of the deflection crank through a pin, and the lower inner side of the deflection crank is connected to the top pressure roller. A torsion spring is provided at the junction of the top pressure roller support and the deflection crank. Multiple sets of guide positioning components on the same side of the multiple guide rollers are connected and fixed by a linkage rod. One end of the linkage rod is provided with a connecting seat. A spacing adjustment rod is connected to the middle of the material conveyor base at the position corresponding to the connecting seat, and two connecting seats are connected to the spacing adjustment rod.

[0006] Preferably, the side pressure roller is arranged vertically along its axis and is located at the same horizontal height above the guide roller.

[0007] Preferably, the top pressure roller is located directly above the guide roller, and the axial direction of the top pressure roller is parallel to the axial direction of the guide roller.

[0008] Preferably, the end of the deflection crank away from the top pressure wheel is integrally formed with an armature support, and the bottom of the armature support is fixed with an armature. The side of the sliding sleeve away from the side pressure wheel bracket is welded with an electromagnet support, and an electromagnet is fixed to the inside of the electromagnet support by bolts. The magnetic end of the electromagnet is located on the side close to the armature, and the magnetic end of the electromagnet is located directly below the armature.

[0009] Preferably, the spacing adjustment rod includes a slide rod and a lead screw. The axial direction of the slide rod and the lead screw is parallel to the axial direction of the guide roller. Two connecting seats are slidably connected to the slide rod and screwed to the lead screw. One end of the lead screw extends out of the material conveyor base, and a handwheel is provided at the end of the lead screw extending out of the material conveyor base.

[0010] Preferably, the lead screw is composed of two threaded rods with opposite helical directions, and two connecting seats are respectively screwed to the two threaded rods of the lead screw. The outer wall of the slide rod is provided with length scale lines, and the length scale lines are engraved along the axial direction of the slide rod.

[0011] Preferably, a brush support is connected between the two sets of guiding and positioning components on the guide roller. The brush support is located directly above the guide roller, and a brush part is provided at the bottom of the brush support. The brush support consists of a first brush branch support and a second brush branch support, which are respectively fixed to the two sets of guiding and positioning components.

[0012] Preferably, the material conveyor base is provided with a chip suction chamber in the middle, and a chip guide plate extending obliquely upward to both sides is provided at the upper end of the chip suction chamber. The chip guide plate extends to the bottom of multiple guide rollers. A cloth filter bag extending into the chip suction chamber is passed through one side of the chip suction chamber, and an exhaust fan is provided at the insertion port of the cloth filter bag.

[0014] The technical effects and advantages of this invention are as follows: 1. This invention uses multiple guide rollers to transport cardboard. At this time, it is necessary to adjust the two sets of guiding and positioning components on the guide rollers to match the size of the cardboard. By turning the handwheel to drive the lead screw, the two threaded sections of the lead screw are respectively screwed to the two connecting seats, thereby simultaneously adjusting the distance between the guiding and positioning components on both sides of the guide roller until the side pressure rollers in the two sets of guiding and positioning components abut against the side of the cardboard, thereby laterally limiting the cardboard and effectively preventing lateral deviation of the cardboard during transportation.

[0015] 2. In this invention, before the cardboard is fed into the guide roller, the electromagnet works to attract the armature with its magnetic end, thereby driving the deflection crank to deflect and lift the top pressure roller, making it easier for the cardboard to enter the guide roller for feeding. Then the electromagnet stops working and disengages from the armature. Under the action of the torsion spring, the top pressure roller rolls and presses the cardboard to feed, effectively preventing the cardboard from lifting during transportation.

[0016] 3. In this invention, a brush support is connected between two sets of guiding and positioning components on the guide roller. The bottom of the brush support is provided with a brush part, which sweeps the surface of the cardboard guided by the guide roller to remove residual paper scraps or dust, ensuring the printing quality of the cardboard. Then, the paper scraps or dust fall onto the chip guide plate for collection. At the same time, the exhaust fan performs air extraction to guide the paper scraps or dust into the chip collection chamber. The air is filtered by a cloth filter bag, and the paper scraps and dust settle in the chip collection chamber. Then, the paper scraps and dust settled in the chip collection chamber fall into the chip collection box for collection. Attached Figure Description

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] This invention provides, for example Figure 1-8The illustrated transport device for printing publications includes a material conveyor base 1, in which multiple guide rollers 2 are arranged. Each guide roller 2 is equipped with a paperboard guiding and positioning device. The guiding and positioning device includes guiding and positioning components 3 disposed on both sides of the guide roller 2. The guiding and positioning components 3 include a sliding sleeve 301 slidably connected to the guide roller 2. A ball bearing 3011 is embedded inside the sliding sleeve 301, and the ball bearing 3011 makes rolling contact with the outer wall of the guide roller 2, reducing contact wear between the sliding sleeve 301 and the guide roller 2, and making the sliding contact between the sliding sleeve 301 and the guide roller 2 smoother. Figure 4 and Figure 6 As shown, a side pressure roller bracket 302 that bends inward is welded to the outer wall of one side of the sliding sleeve 301, and a side pressure roller 3021 is connected to the end of the side pressure roller bracket 302. The axial direction of the side pressure roller 3021 is vertically arranged, and the side pressure roller 3021 is located at the same horizontal height at the upper end of the guide roller 2. When the position of the two sets of guide positioning components 3 on the guide roller 2 is adjusted until the side pressure roller 3021 in the two sets of guide positioning components 3 abuts against the side of the cardboard 7, the cardboard 7 is laterally limited, effectively preventing the cardboard 7 from shifting laterally during transportation.

[0028] Combination Figure 4 , Figure 6 and Figure 8 As shown, a top pressure wheel support 303 extending obliquely upward is welded onto the sliding sleeve 301. The inner side of the upper end of the top pressure wheel support 303 is rotatably connected to the middle part of the deflection crank 304 via a pin, and the inner side of the lower end of the deflection crank 304 is rotatably connected to the top pressure wheel 3041. A torsion spring 305 is provided at the junction of the top pressure wheel support 303 and the deflection crank 304. The top pressure wheel 3041 is located directly above the guide roller 2, and the axial direction of the top pressure wheel 3041 is parallel to the axial direction of the guide roller 2. Under the action of the torsion spring 305, the deflection crank 304 is pulled to deflect, thereby causing the top pressure wheel 3041 to press against the cardboard 7 guided on the guide roller 2, effectively preventing the cardboard 7 from warping during transportation.

[0029] Combination Figure 4 and Figure 7As shown, an armature support 3042 is integrally formed at the end of the deflection crank 304 away from the top pressure wheel 3041, and an armature 3043 is fixed to the bottom of the armature support 3042. An electromagnet support 306 is welded to the side of the sliding sleeve 301 away from the side pressure wheel bracket 302. An electromagnet 307 is fixed to the inside of the electromagnet support 306 by bolts. The magnetic end of the electromagnet 307 is located on the side close to the armature 3043, and the magnetic end of the electromagnet 307 is... Directly below the armature 3043, before the cardboard 7 is guided into the guide roller 2, the electromagnet 307 operates to attract the armature 3043 with its magnetic end, thereby driving the deflection crank 304 to deflect and lift the top pressure roller 3041, making it easier for the cardboard 7 to enter the guide roller 2 for guidance. Then the electromagnet 307 stops working and disengages from the armature 3043. Under the action of the torsion spring 305, the top pressure roller 3041 rolls and presses the cardboard 7 for guidance.

[0030] Combination Figure 1 and Figure 3 As shown, multiple sets of guide positioning components 3 on the same side of multiple guide rollers 2 are connected and fixed by linkage rods 4. One end of the linkage rod 4 is provided with a connecting seat 401. A spacing adjustment rod is connected to the middle of the material conveyor base 1 at the position corresponding to the connecting seat 401. Two connecting seats 401 are connected to the spacing adjustment rod. The spacing adjustment rod adjusts the spacing of multiple sets of guide positioning components 3 on multiple guide rollers 2 simultaneously. The specific structure is as follows: The spacing adjustment rod includes a slide rod 5 and a lead screw 501. The axial directions of the slide rod 5 and the lead screw 501 are parallel to the axial direction of the guide rollers 2. Two connecting seats 401 are slidably connected to the slide rod 5, and two connecting seats 401 are screwed to the lead screw 501. One end of the screw 501 extends outside the material conveyor base 1, and a handwheel 5011 is provided at the end of the screw 501 extending outside the material conveyor base 1. The screw 501 is composed of two threaded rods with opposite helical directions, and two connecting seats 401 are respectively screwed to the two threaded rods of the screw 501. By turning the handwheel 5011, the screw 501 is driven. With the two threaded rods of the screw 501 respectively screwed to the two connecting seats 401, the guide positioning components 3 on both sides of the guide roller 2 are adjusted to be closer or farther apart. The outer wall of the slide rod 5 is provided with a length scale line, and the length scale line is engraved along the axial direction of the slide rod 5 to determine the distance between the guide positioning components 3 on both sides of the guide roller 2.

[0031] Combination Figure 3 and Figure 6As shown, a brush support 6 is connected between the two sets of guide positioning components 3 on the guide roller 2. The brush support 6 is located directly above the guide roller 2. The bottom of the brush support 6 is provided with a brush part 601. The brush part 601 sweeps the surface of the cardboard 7 guided by the guide roller 2 to remove residual paper scraps or dust. The brush support 6 is composed of a first brush branch rod seat and a second brush branch rod seat. The first brush branch rod seat and the second brush branch rod seat are respectively fixed to the two sets of guide positioning components 3. The first brush branch rod seat and the second brush branch rod seat are staggered to meet the structural requirements when adjusting the distance between the two sets of guide positioning components 3 on the guide roller 2.

[0032] Preferably, the first and second brush branch rod seats are staggered, and the bristles of the fixed brush portions 601 partially overlap in the horizontal direction. When the distance between the two sets of guide positioning components 3 changes, the staggered bristles can ensure continuous coverage of the upper surface of the cardboard 7, avoiding cleaning blind spots.

[0033] A chip suction chamber 101 is provided in the middle of the material conveyor base 1. A chip guide plate 1011 extending obliquely upward to both sides is provided at the upper end of the chip suction chamber 101. The bottom of multiple guide rollers 2 extend from the chip guide plate 1011. A cloth filter bag 1012 extends through one side of the chip suction chamber 101 and into the interior of the chip suction chamber 101. An exhaust fan 1013 is provided close to the insertion port of the cloth filter bag 1012. The air intake of the exhaust fan 1013 is aligned with the insertion port of the cloth filter bag 1012. Paper scraps or dust swept off the surface of the cardboard 7 by the brush part 601 fall onto the chip guide plate 1011 for collection. At the same time, the exhaust fan 101 collects the dust. 3. Perform air extraction to guide paper scraps or dust into the dust collection chamber 101, where the air is filtered by a cloth filter bag 1012, causing the paper scraps and dust to settle in the dust collection chamber 101. The bottom of the dust collection chamber 101 is equipped with a connected dust collection chamber 102, which contains a dust collection box 1021. The paper scraps and dust settled in the dust collection chamber 101 fall into the dust collection box 1021 for collection. The dust collection box 1021 is connected to the dust collection chamber 102 via a slide rail assembly, and extends along one side of the dust collection chamber 102 for easy cleaning of the paper scraps and dust collected in the dust collection box 1021.

[0034] Working principle of the invention: In use, multiple guide rollers 2 transport the cardboard 7. At this time, it is necessary to adjust the two sets of guide positioning components 3 on the guide rollers 2 to match the size of the cardboard 7. By turning the handwheel 5011, the lead screw 501 is driven. With the two threaded sections of the lead screw 501 respectively connected to the two connecting seats 401, the distance between the guide positioning components 3 on both sides of the guide rollers 2 is simultaneously adjusted until the side pressure rollers 3021 in the two sets of guide positioning components 3 abut against the side of the cardboard 7, thereby guiding the cardboard 7 forward. Lateral limiting effectively prevents lateral deviation of cardboard 7 during transportation; and before cardboard 7 is guided into guide roller 2, electromagnet 307 works to attract armature 3043 with magnetic end, thereby driving deflection crank 304 to deflect and lift top pressure roller 3041, making it easier for cardboard 7 to enter guide roller 2 for guidance. Then, electromagnet 307 stops working and disengages from armature 3043. Under the action of torsion spring 305, top pressure roller 3041 rolls and presses the cardboard 7 to guide it, effectively preventing cardboard 7 from tilting during transportation.

[0035] A brush support 6 is connected between the two sets of guide positioning components 3 on the guide roller 2. The bottom of the brush support 6 is provided with a brush part 601. The brush part 601 sweeps the surface of the cardboard 7 guided by the guide roller 2 to remove residual paper scraps or dust, ensuring the printing quality of the cardboard 7. Then, the paper scraps or dust fall onto the chip guide plate 1011 for collection. At the same time, the exhaust fan 1013 performs air extraction to guide the paper scraps or dust into the chip collection chamber 101. The air is filtered by the cloth filter bag 1012, and the paper scraps and dust settle in the chip collection chamber 101. Then, the paper scraps and dust settled in the chip collection chamber 101 fall into the chip collection box 1021 for collection.

[0036] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
