Description

Technical Field

[0001] This invention belongs to the technical field of corrugated paper processing equipment, and particularly relates to a fully automatic servo paper guide device for corrugated cardboard. Background Technology

[0002] Currently, corrugated cardboard slits on the market often have burrs and flashes on the paper ends. During digital printing, these burrs and flashes can easily damage, spoil, or clog the printheads of digital printing machines, leading to defective prints and causing economic losses for customers. To address this, a fully automatic servo paper guide device for corrugated cardboard is proposed to solve the problem of burrs and flashes on the paper ends after slitting, which damage, spoil, or clog the printheads of digital printing machines. Summary of the Invention

[0003] The purpose of this invention is to provide a fully automatic servo paper guide device for corrugated cardboard, aiming to solve the problem in the prior art where burrs and sharp edges remain on the corrugated cardboard after slitting, causing damage, blockage, and clogging of the printheads of digital printing presses. To achieve this objective, the technical solution adopted by this invention is: a fully automatic servo paper guide device for corrugated cardboard, comprising a support, a paper guide device, a leading edge feeding device, a paper separating module, and a feeding tray. The leading edge feeding device is installed in the center of the support. The feeding tray and the paper guide device are respectively installed in front of and behind the leading edge feeding device and fixedly connected to the support. The paper separating module is installed above the leading edge feeding device. The corrugated paper enters the paper separating module and the leading edge feeding device from the feeding tray and then enters the paper guide device, where the paper guide device chamfers the corrugated paper head. The paper guide device includes an eccentric wheel lifting mechanism, a motor, a main drive roller, a driven drive roller, a paper guide roller, and a driven pressure roller. The paper guide roller and the driven pressure roller are mounted on the eccentric wheel lifting mechanism, while the main drive roller and the driven drive roller are mounted below them. The motor is connected to the paper guide roller and the main drive roller. The paper guide roller has four raised strips evenly distributed on its circumferential surface. Several sensors are installed on the support and the paper guide roller. This technical solution enables large-scale, fully automated chamfering of corrugated cardboard ends, preventing burrs and sharp edges from damaging the printing press nozzles.

[0004] Further describing the aforementioned solution, the eccentric wheel lifting device includes a lifting frame, a motor, a drive shaft, a rack, and eccentric wheels. The lifting frame, rack, and eccentric wheels are arranged in two sets at the ends of the guide roller and the driven pressure roller, respectively. The rack is connected to the driven pressure roller via a rack-and-pinion connection. The motor drives the drive shaft to rotate the two eccentric wheels, which in turn drives the lifting frame, the guide roller, and the driven pressure roller. The eccentric wheel lifting device raises and lowers the guide roller and the driven pressure roller, thereby adjusting the distance to the main drive roller and the driven drive roller, and performing chamfering processing on corrugated cardboard of different thicknesses. The main drive roller drives the driven roller via gears. The main drive roller is tangentially positioned to the driven pressure roller, and the driven roller is tangentially positioned to the guide roller.

[0005] Further description of the aforementioned scheme: the leading edge feeding device includes a feeding motor and several horizontally arranged rollers. The leading edge feeding device is fixedly mounted on the bracket by support feet to feed the corrugated paper.

[0006] Furthermore, the paper-separating module includes two side baffles, a front baffle, guide posts, and a lead screw. The side baffles are movably mounted on the guide posts and driven by the lead screw to feed corrugated cardboard of different widths. The top of the front baffle is connected to a hexagonal shaft, and the end of the hexagonal shaft is connected to a hexagonal shaft motor. The hexagonal shaft motor drives the hexagonal shaft to change the angle of the front baffle, thereby enabling the single-sheet release of corrugated cardboard of different thicknesses.

[0007] Furthermore, the side panels are connected to the ends of the telescopic protective cover to prevent debris and employees from entering the equipment.

[0008] Even better, the feeding bracket includes a paper separating roller and a paper supporting roller installed in parallel on the adjusting bracket. The bottom of the adjusting bracket is equipped with a rack. The adjusting motor drives the gear on the adjusting transmission shaft to move the adjusting bracket, so as to store corrugated cardboard of different lengths.

[0009] Even better, the entire equipment also includes a protective cover, which is mounted on the bracket and covers the paper guide device, the front feeding device, and the paper separating module, thus protecting the equipment components.

[0010] Compared with existing technologies, this invention uses a paper guide device, a leading edge feeding device, a paper blocking module, and a feeding bracket to chamfer the ends of corrugated paper in batches, quickly and efficiently removing burrs and flashes from the ends of corrugated paperboard, ensuring that the corrugated paperboard will not affect the print head of the printing press during printing, and improving printing quality.

[0027] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention.

[0028] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0029] Please see Figure 1-13 As shown, this invention provides a fully automatic servo paper guide device for corrugated cardboard, including a support 3, a paper guide device 1, a front feeding device 5, a paper separating module 2, and a feeding tray 6. The front feeding device 5 is installed in the center of the support 3. The feeding tray 6 and the paper guide device 1 are respectively installed in front of and behind the front feeding device 5 and fixedly connected to the support 3. The paper separating module 2 is installed above the front feeding device 5. Corrugated paper enters the paper separating module 2 and the front feeding device 5 from the feeding tray 6 and then enters the paper guide device 1. The paper guide device 1 bevels the corrugated paper head. The paper guide head device 1 includes an eccentric wheel lifting device 11, a motor 16, a main drive roller 12, a driven drive roller 13, a paper guide head roller 14, and a driven pressure roller 15. The eccentric wheel lifting device 11 is slidably mounted on a guide rail 19 and a bracket 3. The paper guide head roller 14 and the driven pressure roller 15 are mounted on the eccentric wheel lifting device 11. The main drive roller 12 and the driven drive roller 13 are mounted below the paper guide head roller 14 and the driven pressure roller 15. The motor 16 is connected to the paper guide head roller 14 and the main drive roller 12. Figure 9 As shown, the paper guide roller 14 has four protruding strips 141 that are evenly distributed on the circumferential surface. The bracket 3 and the paper guide roller 14 are equipped with several proximity switches 17 and photoelectric switches 171 to detect the corrugated cardboard and the paper guide roller 14.

[0030] like Figure 4-9 As shown, the eccentric wheel lifting device 11 consists of a lifting frame 111, a rack 112, and an eccentric wheel 113, arranged in two groups at the ends of the guide roller 14 and the driven pressure roller 15, respectively. The rack 112 is connected to the driven pressure roller 15 via a rack and pinion mechanism. The motor 16 drives the transmission shaft to rotate the two eccentric wheels 113, thereby driving the lifting frame 111, the guide roller 14, and the driven pressure roller 15 to move up and down. The eccentric wheel lifting device 11 drives the guide roller 14 and the driven pressure roller 15 to rise and fall, thereby adjusting the distance to the main drive roller 12 and the driven drive roller 13, and performing chamfering processing on corrugated cardboard of different thicknesses. Figure 7 , 8As shown, the main drive roller 12 drives the driven roller 13 through the gear 18. The main drive roller 12 is tangentially arranged with the driven paper pressure roller 15, and the driven roller 13 is tangentially arranged with the paper guide roller 14.

[0031] like Figure 11 As shown, the leading edge feeding device 5 includes a feeding motor 53 and several horizontally arranged rollers 52. The leading edge feeding device 5 is fixedly mounted on the bracket 3 via support feet 51 to feed the corrugated paper. Figure 12 As shown, the paper-separating module 2 includes two side baffles 22, a front baffle 23, guide posts 24, and a lead screw 25. The side baffles 22 are movably mounted on the guide posts 24 and driven by the lead screw 25 to feed corrugated cardboard of different widths. The top of the front baffle 23 is connected to a hexagonal shaft 231, and the end of the hexagonal shaft 231 is connected to a hexagonal shaft motor 232. The hexagonal shaft motor 232 drives the hexagonal shaft 231 to change the angle of the front baffle 23, thereby enabling the single-sheet release of corrugated cardboard of different thicknesses. The side baffles 22 are connected to the end of a telescopic protective cover 21 to prevent debris and employees from entering the equipment.

[0032] like Figure 10 As shown, the feeding bracket 6 includes a paper separating roller 61 and a paper supporting roller 62 mounted parallel to the adjusting bracket 63. An adjusting rack 64 is provided at the bottom of the adjusting bracket 63. An adjusting motor 66 drives a gear 18 on the adjusting transmission shaft 65 to move the adjusting bracket 63, thereby accommodating corrugated cardboard of different lengths. The entire device also includes a protective cover 4, which is mounted on the bracket 3 and covers the paper guide device 1, the leading edge feeding device 5, and the paper separating module 2, thus protecting the equipment components.

[0033] To gain a more thorough and comprehensive understanding of the disclosure of this utility model, its principles will be further explained below in conjunction with its usage.

[0034] In actual use, the length, width, and thickness of the corrugated cardboard are input into the control system, and the length of the feeding bracket 6 is adjusted according to the length of the corrugated cardboard. Figure 10 As shown, by adjusting the motor 66 to drive the adjusting transmission shaft 65, the gear at the end of the adjusting transmission shaft 65 drives the adjusting rack 64 to move, thereby driving the adjusting bracket 63 and the paper separating roller 61 and paper supporting roller 62 mounted on the adjusting bracket 63, so that the length of the feeding bracket 6 is consistent with the length of the corrugated cardboard. Figure 12 As shown, based on the input width of the corrugated cardboard, the lead screw motor 251 drives the lead screw 25 to rotate, thereby adjusting the telescopic protective cover 21 and the side baffle 22 to the appropriate position. Based on the input thickness of the corrugated cardboard, the hexagonal shaft motor 232 drives the hexagonal shaft 231 to rotate, and the hexagonal shaft 231 drives the positive baffle 23 to rotate, as shown. Figure 12As shown, the tilt angle of the baffle 23 is just right for a single piece of corrugated cardboard to pass through; at the same time, the eccentric wheel lifting device 11 lifts and lowers according to the thickness of the input corrugated cardboard, such as... Figure 6-8 As shown, the distance between the main drive roller 12 and the driven pressure roller 15, and between the driven drive roller 13 and the guide roller 14, is just enough for a single piece of corrugated cardboard to pass through.

[0035] After each module is adjusted according to the length, width, and thickness of the input corrugated cardboard, the stacked corrugated cardboard is placed on the feeding tray 6. The feeding function is then activated, and the corrugated cardboard is fed by the front feeding device 5 to the tangent point between the driven pressure roller 15 and the main drive roller 12. The front feeding device 5 stops feeding, and the corrugated cardboard is clamped and driven by the main drive roller 12 and the driven pressure roller 15. When the photoelectric switch 171 detects the paper head, the drive servo motor of the guide roller 14 drives the guide roller 14 to start rotating in the same direction as the corrugated cardboard. When the corrugated cardboard is transported to the tangent position of the driven roller 13, the protrusion strip 141 of the guide roller 14 also rotates to the tangent position with the driven roller 13, at which point the paper head of the corrugated cardboard is pressed into a chamfer, completing the guiding function of one corrugated cardboard sheet. Figure 13 As shown, each time the through-beam photoelectric switch 171 detects a paper head, the paper guide roller 14 rotates 90 degrees and returns to the positioning proximity switch 17 to stop rotating, waiting for a signal from the through-beam photoelectric switch 171. This process is repeated to complete the chamfering of each paper head.
