Description

Technical Field

[0001] The invention relates to the technical field of water-ink printing, in particular to a printing press with an auxiliary paper loading device. Background Art

[0002] A printing press is a device used to print text and patterns on printing carrier materials. There are many types, among which water-based ink printing press is one of them. Water-based ink printing press is mostly used for printing on cardboard or small cartons, and it is the basic equipment of a small carton factory. It is mainly composed of a paper loading and unloading part, a conveyor line part, a positioning part, a printing part (ink supply part, inkjet part) and other parts. When printing on cardboard or small cartons, first the paper loading and unloading part is used to hold the cardboard, and the cardboard is grabbed and sent to the conveyor line by a mechanical arm or an automatic suction cup, and then the positioning part positions it on the conveyor line, and then the ink supply part uses the ink supply pipe to transport the ink in the ink tank to the ink nozzle, and then the computer control system controls the ink nozzle to vibrate at high speed according to the input signal, so that the ink forms a fine spray, which is evenly sprayed and printed on printing materials such as cardboard or small cartons.

[0003] When printing on cardboard, the paper loading part and the conveyor line part are as follows: first, the cardboard is placed in a storage box, and then the intelligent automatic suction cup is extended downward to absorb the cardboard in the storage box, then retracted and then translated to the conveyor line, and then extended and released The suction makes the cardboard fall on the conveyor belt in the conveyor line, and then the conveyor belt moves with the cardboard through the bottom of the printing part above the conveyor line and prints it. After printing is completed, it is transported and dropped by the conveyor line.

[0004] The above intelligent automatic suction cups must be used together with a precise automatic control system, and the overall investment cost is high. The requirements and costs for later maintenance and repair are also not low. For the third-level factories, the ink printing machine is the main body and also accounts for the largest investment. Generally, it also requires a gluer, a stapler and a baler to be used in conjunction with it, which makes the cost investment too high for the third-level factories. For this reason, we propose a printing machine with an auxiliary paper loading device to solve the above problems. Summary of the invention

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Reference Figure 1-14 , a printing press with an auxiliary paper loading device, including a conveyor line structure and a receiving box 4, an ink printing part is arranged above the conveyor line structure, and the cardboard conveyed from the conveyor belt 3 is printed by the ink printing part of the prior art, the conveyor line structure is the prior art including a transmission roller 1 and a squeezing roller 2, there are two transmission rollers 1, and the two transmission rollers 1 are externally sleeved with a conveyor belt 3, the squeezing roller 2 is located between the two transmission rollers 1, it should be noted that the squeezing roller 2 is located close to the position where the cardboard initially falls, and close to the transmission roller 2 at this position, so that when the cardboard falls, the cardboard is squeezed and released to expand the shell 332 to adsorb the cardboard, the transmission roller 1, the squeezing roller 2 is installed between the external support frames, the support frames are not completely drawn and have no number in the figure, and the prior art only needs to know that the inner ring surface of the conveyor belt 3 is provided with a notch 32, and the notch 32 is connected with an air suction member 33, the air suction member 33 includes an expansion shell 332, the expansion shell 332 is made of rubber, and the bottom edge of the expansion shell 332 has a connecting edge 331, the connecting edge 331 is connected to the notch 32 by gluing or riveting, the expansion shell 332 is provided with a resilient body 333, and the middle section of the resilient body 333 is a disc-shaped airbag body, and the disc-shaped airbag body can be better opened after being squeezed, and the outer ring surface of the conveyor belt 3 is provided with an adsorption hole 31 and connected to the notch 32; When the transmission roller 1 rotates to drive the conveyor belt 3 to rotate, the expansion shell 332 of the inner ring of the conveyor belt 3 contacts and is squeezed by the transmission roller 1 and the squeezing roller 2, and the elastic body 333 is also squeezed, and the gas between the notch 333 and the expansion shell 332 is squeezed out through the adsorption hole 31; when the expansion shell 332 leaves the transmission roller 1 and the squeezing roller 2, the elastic restoring force of the expansion shell 332 itself makes the expansion shell 332 return to the bulging state, and at the same time, the disc-shaped airbag end of the elastic body 333 is also restored after being squeezed, so that the elastic body 333 also assists the expansion shell 332 to return to the original bulging state. When the expansion shell 332 swells and recovers, air can be sucked between the recess 333 and the expansion shell 332 through the adsorption hole 31. In this way, when the cardboard to be printed falls on the conveyor belt 3, it is adsorbed on the conveyor belt 3 by the adsorption hole 31, so that the conveyor belt 3 drives the cardboard to be printed to move. When the cardboard is driven by the conveyor belt 3 to pass the printing position and away from the falling position, the expansion shell 332 on the inner ring surface of the conveyor belt 3 is squeezed by the transmission roller 1 away from the falling position. In this way, the gas between the recess 333 and the expansion shell 332 is discharged from the adsorption hole 31 and the adsorption of the cardboard is released, thereby preventing the printed cardboard from being conveyed and falling.

The expansion force of the tension spring 752 can squeeze the pressing plate 753 downward onto the cardboard placed in the receiving box 4, and there is a moving gap between the two ends of the pressing plate 753 and the inner wall of the receiving box 4.

[0031] Reference Figure 1-14 A printing press with an auxiliary paper loading device, a double-sided rack B8 is sleeved on the locking rod 46 through a through hole 81, a square hole 411 is opened on the side plate 41 for the double-sided rack B8 to pass through, a positioning assembly 9 is provided on the side plate 41, and the positioning assembly 9 includes two mounting blocks G91, and the two mounting blocks G91 have connecting blocks on opposite sides, and the connecting blocks are connected to the side plate 41 by bolts, and the two mounting blocks G91 are respectively located on both sides of the square hole 411, and two positioning gears 92 are rotatably connected between the two mounting blocks G91 through two shafts, and the two positioning gears 92 are located above and below the square hole 411, and the two positioning gears 92 are meshed and matched with the double-sided rack B8.

[0032] Reference Figure 1-14 , a printing press with an auxiliary paper loading device, before the double-sided rack B8 is inserted into the square hole 411, it must first pass through the two positioning gears 92. When the double-sided rack B8 is pushed forward, the two positioning gears 92 rotate to ensure the position of the double-sided rack B8 in this way, that is, to ensure that one tooth surface of the double-sided rack B8 is on the top and the other tooth surface is on the bottom, and the double-sided rack B8 is continuously pushed to move and pass over the transmission gear C722, driving the transmission gear C722 to rotate counterclockwise, and then continue to push the double-sided rack B8 to move through the transmission gear A712 and rotate clockwise until the end of the double-sided rack B8 abuts against the inner surface of the receiving box 4. At this time, the locking rod 46 is in the through hole 81, and the locking rod 46 is rotated to make the end without the faceplate screwed to the inner surface of the receiving box 4, and at the same time, the double-sided rack B8 is locked and immovable; In the process that the transmission gear C722 rotates counterclockwise and the transmission gear A712 rotates clockwise, the transmission gear C722 drives the transmission rod B721 to rotate, the transmission gear A712 drives the transmission rod A711 to rotate, the transmission rod B721 drives the two transmission gears B713 to rotate, and the transmission rod A711 drives the two transmission gears D723 to rotate. Since the double-sided rack A732 is meshed between a transmission gear B713 and a transmission gear D723, when the transmission gear B713 rotates counterclockwise and the transmission gear D723 rotates counterclockwise, the double-sided rack A732 is driven to move downward by the principle of meshing transmission. It should be noted that the outer displacement rod 731 and the inner displacement rod 733 The initial state is higher than the top of the storage box 4, which is not shown in the figure. The reason is that the tension spring 75 squeezes the stopper 742 upward, and the stopper 742 drives the outer displacement rod 731 and the inner displacement rod 733 upward through the adjusting rod 741. When the double-sided rack A732 moves downward, the outer displacement rod 731 and the inner displacement rod 733 move downward, the adjusting rod 741 and the stopper 742 move downward, and the stopper 742 moves downward on the surface of the movable rod 751 and squeezes the tension spring 72. Further, the tension spring 72 squeezes the pressure plate 753 on the cardboard in the storage box 4 to provide a little downward pressure on the cardboard, increase some pressure between the cardboard and the wheel sleeve 522, and help the wheel sleeve 522 to roll the cardboard out of the storage box 4.
