Description

Technical Field

[0001] This patent relates to a processing equipment for office paper products, and more particularly to a multifunctional printing paper production equipment. Background Technology

[0002] Computer printing paper can be categorized by the number of layers into single-layer and multi-layer paper. Multi-layer paper, made from carbonless copy paper, is also known as carbonless copy paper and is primarily used in dot matrix printers. It can also be categorized by printing method into folded paper and single-copy paper. Folded paper is suitable for continuous printing, while single-copy paper is suitable for flatbed printers. To achieve continuous paper feeding, folded paper typically requires feed holes on both sides for precise feeding by the printer's chain teeth. Computer printing paper can also be categorized by whether it contains pre-printed content into printed paper and blank paper. Furthermore, it can be categorized by whether it has tear-off edges into tear-off paper and non-tear-off paper. In practical applications, different combinations of paper layers, fold / single-copy configurations, feed holes, and printing characteristics can create a wide variety of products. In existing production equipment and processes, folded printing paper, single-sheet printing paper, and printed printing paper are produced using different equipment and processes. For example, folded printing paper is produced using multi-layer or single-layer folded printing paper production equipment. Single-sheet printing paper is produced by first producing folded printing paper and then tearing and trimming it, or by cutting a large sheet of paper into smaller sheets and then collating and trimming it. Printed printing paper is produced by first printing single sheets and then collating them. These production methods use a variety of equipment, have long process flows, low production efficiency, and require multiple processing allowances, resulting in high costs. Summary of the Invention

[0003] The purpose of this patent is to provide a multifunctional printing paper production device that solves the technical problem of directly producing finished products from various types of printing paper on a single production line.

[0004] To achieve the above objectives, this patent adopts the following technical solution: This multifunctional printing paper production equipment includes multiple sets of unwinding stations, a web guiding device, a printing device, an easy-tear line cutting device, a marking device, a locking device, a paper pressing device, a punching device, a paper pressing conveyor, a cutting device, a separating conveyor, a stacking conveyor, and a vibrating paper receiving table arranged in sequence. It also includes a paper pulling conveyor installed above the separating conveyor, a folding device installed above the stacking conveyor, and a control system for the equipment. The control system includes a controller, a touch screen, an encoder installed at the end of the bottom blade roller, a servo motor installed at the end of the loading blade roller, and a computer. The controller is electrically connected to the touch screen, encoder, servo motor, traction electromagnet, and computer. The computer is electrically connected to multiple printheads.

[0005] The separating conveyor is installed at a downward inclination behind the cutting device, and includes a lower conveyor belt and an upper conveyor belt. The lower conveyor belt and the upper conveyor belt are installed in a staggered manner, and the conveying line speed of the separating conveyor is higher than the paper pressing conveyor line speed.

[0006] The superimposed conveyor is installed behind and below the separating conveyor, and the speed of the conveyor belt is lower than that of the separating conveyor. The superimposed conveyor includes a flat belt group consisting of two interconnected and angle-adjustable flat belt groups, and an auxiliary pressure roller on the flat belt group.

[0007] The paper-pulling conveyor is installed above the separating conveyor and connected to the cutting device. It includes a drive roller and a pair of rubber pressure rollers mounted on the drive roller, as well as a support roller and a pressure roller installed in front of the drive roller. The folding device is installed above the stacking conveyor and connected to the rear and lower part of the paper-pulling conveyor. It includes a swing frame, with a pair of spiral folders installed on each side of the swing frame.

[0008] Compared with existing technologies, the beneficial effects of this patent are as follows: The multifunctional printing paper production equipment and method described in this patent include most of the production equipment and methods for producing single-sheet printing paper, folded printing paper, blank printing paper, and printed printing paper. Multiple production processes can be formed by adjusting the various devices within the equipment to produce different types of printing paper. Furthermore, this production process and equipment uses roll paper as raw material for continuous production, reducing the turnover of intermediate semi-finished products and improving production efficiency. The paper is precisely cut to length, allowing for direct production of finished products without secondary precision cutting or leaving processing allowances, thus reducing processing losses associated with traditional production methods. This technical solution solves the technical problem of directly producing finished products of various types of printing paper on a single production line. Attached Figure Description

Detailed Implementation

[0019] To make the implementation purpose, technical solution and advantages of this patent clearer, the following detailed description of the patent solution by way of embodiments, in conjunction with the accompanying drawings, is provided.

[0020] As shown in the schematic diagram of the production equipment in Figure 1, this multifunctional printing paper production equipment includes multiple sets of unwinding stations 10, a web guiding device 11, a printing device 12, an easy-tear line cutting device 13, a marking device 14, a locking device 15, a paper pressing device 16, a punching device 17, a paper pressing conveyor 18, a cutting device 19, a separating conveyor 20, a stacking conveyor 21, and a vibrating paper receiving table 22, and also includes a paper pulling conveyor 23 installed above the separating conveyor 20, a folding device 24 installed above the stacking conveyor 21, and a control system 99. The structure of each device is described in detail below.

[0021] As attached Figure 2As shown, the unwinding station 10 includes two wall plates 103. The upper paper 1, middle paper 2, and lower paper 3 are respectively mounted on an unwinding shaft 102. Both ends of the unwinding shaft 102 are mounted on the upper ends of the wall plates 103 via bearings. One end is also connected to a magnetic powder clutch 104, which is fixedly mounted on the upper side of one wall plate 103. At least one guide roller 101 is also installed between the two wall plates 103. This embodiment has three unwinding stations 10, which can produce three-piece products. When producing four-piece products, one more unwinding station 10 is added. Similarly, for other numbers of pieces, the corresponding number of unwinding stations 10 is added. When producing two-piece products, only two of the unwinding stations 10 can be used. When producing single-layer products, only one unwinding station 10 can be used. That is, the number of unwinding stations 10 is configured according to the number of pieces in the equipment configuration.

[0022] The technical solution of the correction device 11 can be composed of multiple high-precision CNC correction devices (utility model patent number: 2019224780041) designed by our company in 2019, which are stacked and combined. The correction device 11 is used to correct the deviation phenomenon that occurs during the transmission of paper after unwinding to the normal position.

[0023] The printing apparatus 12 includes a printing bracket 122 with multiple paper guide rollers 101 and at least one printhead 121, with one printhead 121 for each layer of paper. The printing position of each layer of paper can be adjusted by adjusting the longitudinal mounting position of the printhead 121. This printhead 121 uses existing mature industrial inkjet printing technology, and the images are pre-stored in a computer 995 (as shown in the attached document). Figure 3 As shown, the computer 995 controls the printhead 121 to print preset images and text onto the paper. The printhead 121 can be a color inkjet printhead, capable of producing both color and black-and-white graphic products.

[0024] The easy-tear line cutting device 13 includes a bottom roller 131, and at least one set of circular dotted line cutters 132 are installed above the bottom roller 131, pressing against the bottom roller 131. When the paper passes over the bottom roller 131, pressing down the circular dotted line cutters 132 continuously cuts longitudinal easy-tear lines on the paper. Depending on the product requirements, multiple circular dotted line cutters 132 can be installed simultaneously above the bottom roller 131 to cut multiple longitudinal easy-tear lines. Using two sets of circular dotted line cutters 132, easy-tear lines can be cut on both sides of the paper.

[0025] The marking device 14 includes a pen clip 143, one end of which holds a marker pen 141, and the other end is connected to a traction electromagnet 142. The pen clip 143 also has a rotating shaft, as shown in the attached figure. Figure 3As shown. The action of the traction electromagnet 142 depresses the marker pen 141, drawing a book-division mark on the paper. The timing of the traction electromagnet 142's action is based on the preset number of copies per book. The controller 991 of the control system 99 counts the number of cuts made by the cutter 192 of the cutting device 19. Once the preset number of copies is reached, the traction electromagnet 142 is activated. Drawing book-division marks is used to control the number of copies per finished product. After paper collection, the copies can be manually removed according to the marks, and then each book can be packaged as a finished product.

[0026] The locking device 15 includes a grooved bottom mold 151 and an upper die 152. The bottom mold 151 and die 152 are each mounted on a drive shaft. A locking blade 153 is mounted on the die 152. The blade of the locking blade 153 is pressed into the groove of the bottom mold 151 by rotational force, pressing the paper through it to form a locking code and riveting the layers of paper together. The blade of the locking blade 153 includes at least two pairs of evenly spaced V-shaped cutting edges that match the groove of the bottom mold 151.

[0027] The paper pressing device 16 is installed behind the pressure locking device 15 and includes an adjustable upper pressure roller 161 and a lower roller 162. The paper pressing device 16 is used to adjust the wrap angle of the paper on the bottom die 151 to increase the stability of paper conveying.

[0028] The punching device 17 is installed behind the paper pressing device 16 and includes a punching plate 171 and a punching plate 172. The punching plate 171 and the punching plate 172 are respectively installed on the drive shaft. Punch nuts are arranged in a circular pattern on the punching plate 171, and punches that cooperate with the punch nuts are arranged in a circular pattern on the punching plate 172. The punches and punch nuts can press the paper through the conveying hole by rotating and cooperating with each other.

[0029] The paper conveying device 18 includes a rubber pressure roller 181 pressing on the bottom knife roller 191 of the cutting device 19, and a lower support roller 182 installed in front of the rubber pressure roller 181. The rotation of the bottom knife roller 191 generates tension on the paper, causing the paper to be conveyed backward. The lower support roller 182 increases the contact area of ​​the paper on the rubber pressure roller 181, ensuring that the paper does not slip during conveying and making the paper conveying more stable. The tension of the upper paper 1, middle paper 2, and lower paper 3 is determined by the braking force of the magnetic powder clutch 104 installed on the unwinding seat 10. The braking force generated by the magnetic powder clutch 104 is controlled by adjusting its current. Therefore, each magnetic powder clutch 104 is equipped with a current regulator to adjust the tension of each layer of paper to ensure smooth paper conveying.

[0030] The cutting device 19 includes a bottom cutter roller 191 and a cutting roller 193. The cutting roller 193 has a long groove on its circumference for mounting a straight cutter 192. The cutter 192 is mounted on the cutting roller 193 and cuts the paper passing over the surface of the bottom cutter roller 191 by rotating pressure on the bottom cutter roller 191. In the process of producing a single finished product, in order to cut the paper under tension, the head of the paper enters the separating conveyor 20 before cutting. The conveying linear speed of the separating conveyor 20 is set to be higher than the linear speed of the paper pressing conveyor. Tension is generated between the head of the paper and the rubber pressure roller 181, so that the paper is cut into a single finished product 4 under tension.

[0031] The separating conveyor 20 is installed at a downward angle behind the cutting device 19. It includes a lower conveyor belt 201 and an upper conveyor belt 202. The lower conveyor belt 201 and the upper conveyor belt 202 are installed in a staggered manner and their surfaces are close together. When the paper comes out of the cutting device 19, it is driven by the rotation of the upper conveyor belt 202 and is clamped between the lower conveyor belt 201 and the upper conveyor belt 202 and conveyed backward. Since the conveying line speed of the separating conveyor 20 is set to be higher than the line speed of the paper pressing conveyor 18, the paper head can generate tension at the rubber pressure roller 181 under the action of belt friction before the paper is cut. After cutting, the single finished product 4 can quickly leave the cutter 192 and be conveyed backward quickly with intervals. The staggered installation of the lower conveyor belt 201 and the upper conveyor belt 202 and their surfaces being close together can make the upper and lower belt rollers of metal material staggered with each other, so that there is elastic contact between the upper and lower belts. After the paper enters, it will not cause discoloration due to excessive local pressure. The upper conveyor belt 202 is detachable and is not needed when producing folded finished products 5, so it can be easily removed.

[0032] The stacking conveyor 21 is installed behind and below the separating conveyor 20, and its conveyor belt speed is lower than that of the separating conveyor 20. This allows the head of the incoming single-piece finished product 4 to press against the tail of the incoming single-piece finished product 4, enabling the heads and tails of the two single-piece finished products 4 to overlap. The stacking conveyor 21 includes a flat belt group 211 composed of two sets of interconnected and angle-adjustable flat belts. An auxiliary pressure roller 212 is also mounted on the flat belt group 211. The flat belt group 211, composed of two sets of angle-adjustable flat belts, allows the single-piece semi-finished product 4 to be raised during subsequent transport to accommodate the operating height of the rear vibrating paper receiving table 22. The auxiliary pressure roller 212 on the flat belt group 211 uses its own weight and passive rotation to press down on the single-piece finished product 4, ensuring the paper does not loosen during transport and providing a smoother conveying process. The auxiliary pressure roller 212 is detachable and is not needed when producing folded finished products 5, allowing for easy removal.

[0033] The vibrating paper receiving table 22 can be a vibrating paper receiving table with three-level vibration reduction and automatic lifting function developed by our company (utility model patent number: 2020217053187). The table panel of the vibrating paper receiving table 22 is behind the stacking conveyor 21 and lower than the belt surface of the flat belt group 211, and is tilted backward so that the conveyed single finished product 4 can fall on the table panel, and the single finished product 4 is stacked neatly one by one through high-frequency vibration.

[0034] When the product being produced is a single finished product 4, the cutter 192 installed on the cutter roller 193 of the cutting device 19 is a straight cutter. The cutter 192 can completely cut the paper passing over the surface of the bottom cutter roller 191 by rotating pressure on the bottom cutter roller 191. The paper is then conveyed to the vibrating paper receiving table 22 through the separating conveyor 20 and the stacking conveyor 21 to form a neatly stacked single finished product 4.

[0035] The paper conveying device 23 is installed above the separating conveying device 20 and connected to the cutting device 19. It includes a drive roller 231 and a pair of rubber pressure rollers 232, as well as a support roller 233 and a pressure roller 234 installed in front of the drive roller 231. The pair of rubber pressure rollers 232 are mounted on a rubber pressure roller shaft 232-1 and their axial position can be adjusted according to the paper width. The paper conveying device 23 uses the drive roller 231 and the rubber pressure rollers 232 to press the paper and convey it under tension. The support roller 233 and the pressure roller 234 can maintain stable paper conveying.

[0036] The folding device 24 is installed above the stacking conveyor 21 and below the paper pulling conveyor 23, and includes a frame 241, as shown in the attached figure. Figure 1 As shown, a pair of spiral folders 242 are installed on each side of the display stand 241.

[0037] As attached Figure 3 The diagram shown is an installation schematic of the swing frame 241, the drive roller 231, and the rubber pressure roller 232. For ease of description, please refer to the attached diagram. Figure 3 The position of the components is indicated by the front end (near end) being called the operating side and the rear end (far end), which is the direction of the main power transmission of the equipment being called the transmission side. For ease of reading, the operating side and transmission side of some components with the same serial number are both marked. At the same time, to simplify the drawing, some common auxiliary components that do not involve the main structure, such as keys, positioning sleeves, glands, screws, etc., are not shown in the drawing, and their textual descriptions are also omitted.

[0038] The swing frame 241 includes a pair of brush rollers I 241-1 and II 241-2 that are in contact with each other. The brush rollers are made by winding nylon brush strips around steel rollers. The main purpose of using a pair of brush rollers to transport paper is to guide the paper correctly and reduce the pressure on the paper, preventing the paper from being stressed and discolored during the swinging process. Brush roller I 241-1 is mounted on the fixed block 241-3 at both ends by bearings. Brush roller II 241-2 is mounted on the fixed block 241-3 at both ends by bearings and eccentric sleeves 241-4 that mount the bearings. The outer circle of the eccentric sleeve 241-4 is in sliding fit with the mounting hole of the fixed block 241-3, and the eccentric sleeve 241-4 is fastened to the side of the fixed block 241-3 by screws. The brush roller II 241-2 is mounted with eccentric sleeves 241-4 at both ends. The gap between brush roller II 241-2 and brush roller I 241-1 can be flexibly adjusted by rotating the eccentric sleeves 241-4, ensuring appropriate paper pressure during transmission. This is especially beneficial after brush wear, as adjusting the gap can extend the service life of the brush rollers. Meshing brush roller gears 241-5 are installed inside the drive-side fixing blocks 241-3 of brush roller I 241-1 and brush roller II 241-2 to ensure consistent rotational speeds of the two rollers. A synchronous pulley I 241-6 is installed at the outer end of the operating-side fixing block 241-3 of brush roller I 241-1. The synchronous pulley I 241-6 is connected to the synchronous pulley II at the operating-side end of the rubber pressure roller shaft 232-1, which mounts the rubber pressure roller 232, via a synchronous belt 241-7 to obtain rotational power.

[0039] The upper end of the fixing block 241-3 is fixed to the lower end of a corner plate 241-8 by screws. A pair of bent guide plates 241-9 are fixedly installed between the two corner plates 241-5 directly above brush roller I 241-1 and brush roller II 241-2, forming a funnel-shaped guide groove 241-10, which is reinforced and fixed by a reinforcing roller 241-11. In addition to connecting the two corner plates 241-5, the guide groove 241-10 also facilitates paper feeding during the machine setup stage and ensures stable paper feeding during operation.

[0040] Two corner plates 241-8 are fixedly mounted on the upper ends of the swing frame handle 241-12. The middle of the swing frame handle 241-12 is connected to both ends of the drive roller 231 via bearings, allowing the drive roller 231 to rotate freely within the swing frame handle 241-12. The contact line between the drive roller 231 and the rubber pressure roller 232 is directly above the guide groove 241-10. Paper can fall into the guide groove 241-10 after the drive roller 231 rotates 90 degrees. After the drive roller 231's drive-side journal extends from the swing frame handle 241-12, a sprocket 231-1 is also fixedly mounted, as shown in the attached diagram. Figure 4 As shown. The rotational power of the main unit is obtained through sprocket 231-1.

[0041] A movable block 241-14 is also mounted on the swing arm handle 241-12 via a pin 241-13. The movable block 241-14 is connected to both ends of the rubber pressure roller shaft 232-1 via bearings, allowing the rubber pressure roller shaft 232-1 to rotate freely within the movable block 241-14. The pin 241-13 is located above the rubber pressure roller shaft 232-1. A stepped through-hole is located on the lower side of the movable block 241-14 below the rubber pressure roller shaft 232-1. An adjusting screw 241-15 within the stepped through-hole, via a pressure spring, mounts the lower end of the movable block 241-14 onto the swing arm handle 241-12. The adjusting screw 241-15 is used to adjust the contact pressure between the rubber pressure roller 232 and the drive roller 231 to ensure smooth paper feeding. A synchronous pulley II (not shown in the figure as it is not visible) is mounted on the end of the rubber pressure roller shaft 232-1 within the movable block 241-14 on the operating side.

[0042] The drive roller 231 and rubber pressure roller shaft 232-1 on the inner side of the swing frame handle 241-12 are also equipped with a pair of meshing transmission gears 231-2. The sprocket 231-1 obtains the rotational power of the main machine and transmits it to the rubber pressure roller shaft 232-1 through the pair of gears. Then, through the synchronous pulley II, synchronous belt 241-7, and synchronous pulley I 241-6, the rotational power is transmitted to the brush roller I 241-1. Then, through the brush roller gear 241-5, it is transmitted to the brush roller II 241-2, which ensures the rotational operation of the swing frame 241 and enables paper feeding.

[0043] The swing arm handle 241-12 is mounted on the hoisting frame 241-16 via bearings, and the hoisting frame 241-16 is hoisted onto the main unit by bolts.

[0044] As attached Figure 3 As shown, a swing arm 241-17 is also installed on the outer circular surface of the portion of the swing frame handle 241-12 extending out of the hoisting frame 241-16 on the transmission side. A swing rod 241-18 is installed at the lower end of the swing arm 241-17 via a pin. The main power source reciprocates through the swing rod 241-18 to push the swing arm 241-17, causing the swing frame handle 241-12 to swing in a fan shape, thereby causing the components installed on the swing frame handle 241-12 to swing, thus causing the entire swing frame 241 to swing. After passing through the drive roller 231, the paper enters the guide groove 241-10, and is then output to the stacking conveyor 21 by brush roller I 241-1 and brush roller II 241-2.

[0045] When the product being produced is a folded finished product 5, the cutter 192 mounted on the cutting roller 193 of the cutting device 19 is a dotted-line cutter. The cutter 192, through rotational pressure, cuts the paper passing through the bottom cutter roller 191 to create a transverse tear line, i.e., a folding line. The paper is then conveyed to the rack 241 of the folding device 24 via the paper conveying device 23. The rack 241 then moves the paper back and forth to the spiral folders 242 on both sides. The spiral folders 242 fold the paper downwards along the folding line by spiral rotation, allowing it to fall onto the stacking conveyor 21 and be stacked and conveyed backwards. The paper then falls onto the vibrating delivery table 22 and is stacked neatly. At this time, the vibrating delivery table 22 needs to have its vibration power turned off. Since the folded finished product 5 is folded along the folding line, vibration is not required for neat stacking.

[0046] As attached Figure 5 As shown, the control system 99 includes a controller 991, a touch screen 992, an encoder 993 mounted on the end of the bottom cutter roller 191, a servo motor 994 mounted on the end of the loading roller 73, and a computer 995. The controller 991 is electrically connected to the touch screen 992, the encoder 993, the servo motor 994, the traction electromagnet 142, and the computer 995. The computer 995 is electrically connected to multiple printheads 121.

[0047] The production equipment described in the above embodiments can be used to implement various methods for producing printing paper. The following examples of representative process flow embodiments illustrate how the equipment is used.

[0048] As attached Figure 6 The process flow shown is one for producing blank, unprinted single-sheet printing paper, and includes the following steps:

[0049] Process 1000: Unwinding the roll: Using roll paper as raw material, the paper is unwound on the unwinding station 10 by the guide roller 101 under the pulling force of the paper conveying device 18, and the top paper 1, middle paper 2, and bottom paper 3 are then conveyed and unwound separately. In this embodiment, it is a three-part product, i.e., there is one layer of middle paper 2. When producing a four-part product, an additional layer of middle paper 2 is added. Similarly, for other numbers of parts, the corresponding number of layers of middle paper 2 are added. The number of unwinding stations 10 is configured according to the number of parts. When producing a two-part product, the middle paper 2 is removed, and only the top paper 1 and bottom paper 3 are used. When producing a single-layer product, the middle paper 2 and bottom paper 3 are removed, and only the top paper 1 is used. Multi-part products use carbonless copy paper as raw material, while single-layer products can use writing paper as raw material.

[0050] Process 2000 Correction: The correction device 11 is used to correct the deviation of the paper during the unwinding and transmission process to the normal position.

[0051] Process 3000: Page setting: Stack the unwound continuous paper together in the order of top paper 1, middle paper 2 and bottom paper 3, and pass it over the upper surface of the bottom roller 131 of the easy-tear line cutting device 13.

[0052] Step 4000 Cutting longitudinal tear lines: The circular dotted line knife 132 on the tear line cutting device 13, which is pressed against the upper surface of the bottom roller 131, cuts longitudinal tear lines on the folded paper. Two sets of circular dotted line knives 132 can be used to cut tear lines on both sides of the paper.

[0053] Process 4500 Marking the Books: Marking each book of the product according to the set number of copies is marked on the paper using the marker pen 141 of the marking device 14; the control method is that the controller 991 of the control system 99 counts the number of cuts by the cutter 192 of the cutting device 19. When the preset number of copies is reached, the controller controls the traction electromagnet 142 of the marking device 14 to activate, pressing down the marker pen 141 to draw a mark on the paper.

[0054] Process 5000: Pressing and locking: Use two sets of pressing and locking devices to press and lock the paper on both sides, and rivet the layers of paper together.

[0055] Step 6000: Paper Pressing and Conveying: The pressure applied by the rubber pressure roller 181 of the paper pressing and conveying device 18 to the bottom knife roller 191 of the cutting device 19, along with the rotation of the bottom knife roller 191, generates tension on the paper, causing it to be conveyed backward. A paper pressing device 16 is located before the paper pressing and conveying device 18. The wrap angle of the paper on the rubber pressure roller 181 is adjusted by the height-adjustable upper pressure roller 161, lower roller 162, and lower support roller 182, increasing the stability of paper conveying. The tension of the upper paper 1, middle paper 2, and lower paper 3 is determined by the braking force of the magnetic powder clutch 104 mounted on the unwinding station 10. The braking force generated by the magnetic powder clutch 104 is controlled by adjusting its current; therefore, each magnetic powder clutch 104 is equipped with a current regulator to adjust the tension of each layer of paper, ensuring smooth paper conveying.

[0056] Step 7000: Cutting into Single Pieces: The continuous paper with the sheets arranged is cut by the cutter 192 of the cutting device 19, which presses it against the bottom knife roller 191 with rotational pressure. The paper, passing under tension, becomes a single piece of finished product 4 according to the designed finished product length. The cutter 192 is mounted on the knife roller 193 and presses it against the bottom knife roller 191 with rotational pressure to cut the paper on the bottom knife roller 191. In order to cut the paper under tension, the head of the paper has entered the separation conveyor 20 before cutting. The conveying linear speed of the separation conveyor 20 is set higher than the paper pressing conveyor linear speed, so that tension force is generated between the head of the paper and the rubber pressure roller 181, so that the paper is cut under tension.

[0057] Process 8000 Separation Conveying: The conveying line speed of the separation conveying device 20 is set to be higher than that of the paper pressing conveying device 18. After the cut single finished product 4 enters the separation conveying device 20, a gap is created, and it is quickly conveyed backward.

[0058] Because the linear speed of the separating conveyor 20 is higher than that of the paper pressing conveyor 18, tension can be generated at the head of the paper to the rubber pressure roller 181 under the action of belt friction before the paper is cut. After cutting, the single finished product 4 can quickly leave the cutter 192 and be quickly conveyed backward with intervals. The lower conveyor belt 201 and the upper conveyor belt 202 are installed in a staggered manner and the belt surfaces are close together, which can make the upper and lower belt rollers of metal material stagger each other, so that there is elastic contact between the upper and lower belts. After the paper enters, it will not cause discoloration due to excessive local pressure.

[0059] Process 9000: Overlapping Conveying: The single finished product 4 from the separating conveyor 20 falls onto the overlapping conveyor 21 and continues to be conveyed. The overlapping conveyor 21 is connected after the separating conveyor 20 of the previous process and is lower than the separating conveyor 20. The speed of the conveyor belt is lower than the speed of the separating conveyor 20, so that the head of the single finished product 4 entering later can press on the tail of the single finished product 4 entering earlier, so that the heads and tails of the single finished products 4 can overlap each other and then be conveyed to the next process.

[0060] Process 9500 Vibration paper collection: Use the vibration paper collection table 22 to stack the individual finished products 4 neatly one by one using high-frequency vibration.

[0061] As attached Figure 7 The second process flow shown describes a method for producing single-sheet printed paper. Based on process flow one, after the correction step (step 2000) and before the collating step (step 3000), the following additional steps are performed:

[0062] Process 2500 Printing: The printer head 121 is controlled by computer 995 to print the preset graphics on the paper. The printer head 121 can be a color inkjet print head, which can produce color and black and white graphic products.

[0063] In the process flow 1 and 2 of the above embodiment, in the process of cutting into single pieces in step 7000, the process of becoming a single finished product 4 according to the designed finished product length is specifically as follows: the encoder 993 feeds back the rotation speed of the bottom blade roller 191 to the controller 991. The controller 991 calculates the linear speed of the paper running according to the received rotation speed signal and the diameter of the bottom blade roller 191. Then, according to the length of the finished product preset on the touch screen 992 and the rotation diameter of the blade 192 on the blade roller 193, the controller calculates the rotation speed of the blade roller 193. The controller feeds back and controls the servo motor 994 to drive the blade roller 193 to rotate according to the obtained rotation speed, so that the blade 192 presses the bottom blade roller 191 with rotational pressure to cut the paper into a finished product of the designed length. This method changes the traditional technical solution of using different diameter cutting rollers to control the cutting length, solves the problem of having to replace the cutting rollers when changing length specifications, and allows the length to be set arbitrarily within the range of 120mm to 500mm without being limited by transmission gears. Moreover, the dimensional accuracy of the cutting length can reach 0.1mm, which meets and exceeds the product size deviation standard of ±0.5mm.

[0064] As attached Figure 8 The process flow shown in step three describes a method for producing blank folded printing paper without printing. This method includes the following steps:

[0065] Process 1000: Unwinding the roll: Using roll paper as raw material, the paper is unwound on the unwinding station 10 by the guide roller 101 under the pulling force of the paper conveying device 18, and the top paper 1, middle paper 2, and bottom paper 3 are then conveyed and unwound separately. In this embodiment, it is a three-part product, i.e., there is one layer of middle paper 2. When producing a four-part product, an additional layer of middle paper 2 is added. Similarly, for other numbers of parts, the corresponding number of layers of middle paper 2 are added. The number of unwinding stations 10 is configured according to the number of parts. When producing a two-part product, the middle paper 2 is removed, and only the top paper 1 and bottom paper 3 are used. When producing a single-layer product, the middle paper 2 and bottom paper 3 are removed, and only the top paper 1 is used. Multi-part products use carbonless copy paper as raw material, while single-layer products can use writing paper as raw material.

[0066] Process 2000 Correction: The correction device 11 is used to correct the deviation of the paper during the unwinding and transmission process to the normal position.

[0067] Process 3000: Page setting: Stack the unwound continuous paper together in the order of top paper 1, middle paper 2 and bottom paper 3, and pass it over the upper surface of the bottom roller 131 of the easy-tear line cutting device 13.

[0068] Step 4000 Cutting longitudinal tear lines: The circular dotted line knife 132 on the tear line cutting device 13, which is pressed against the upper surface of the bottom roller 131, cuts longitudinal tear lines on the folded paper. Two sets of circular dotted line knives 132 can be used to cut tear lines on both sides of the paper.

[0069] Process 4500 Marking the Books: Marking each book of the product according to the set number of copies is marked on the paper using the marker pen 141 of the marking device 14; the control method is that the controller 991 of the control system 99 counts the number of cuts by the cutter 192 of the cutting device 19. When the preset number of copies is reached, the controller controls the traction electromagnet 142 of the marking device 14 to activate, pressing down the marker pen 141 to draw a mark on the paper.

[0070] Process 5000: Pressing and locking: Use two sets of pressing and locking devices to press and lock the paper on both sides, and rivet the layers of paper together.

[0071] Process 5500: Drilling feed holes: Use two sets of drilling devices 17 to drill feed holes between the locks on both sides of the paper. The feed holes are matched according to the specifications of the printer's feed chain teeth, generally with a hole diameter of 4mm and a hole spacing of 12.7mm.

[0072] Step 6000: Paper Pressing and Conveying: The pressure applied by the rubber pressure roller 181 of the paper pressing and conveying device 18 to the bottom knife roller 191 of the cutting device 19, along with the rotation of the bottom knife roller 191, generates tension on the paper, causing it to be conveyed backward. A paper pressing device 16 is located before the paper pressing and conveying device 18. The wrap angle of the paper on the rubber pressure roller 181 is adjusted by the height-adjustable upper pressure roller 161, lower roller 162, and lower support roller 182, increasing the stability of paper conveying. The tension of the upper paper 1, middle paper 2, and lower paper 3 is determined by the braking force of the magnetic powder clutch 104 mounted on the unwinding station 10. The braking force generated by the magnetic powder clutch 104 is controlled by adjusting its current; therefore, each magnetic powder clutch 104 is equipped with a current regulator to adjust the tension of each layer of paper, ensuring smooth paper conveying.

[0073] Step 7010: Cutting Fold Lines: The aligned continuous paper is pressed onto the bottom cutter roller 191 by the dotted-line cutter 192 of the cutting device 19 under rotational pressure, so that the paper passing through under tension is cut with fold lines according to the designed length of each finished product. At this time, the cutter 192 is a dotted-line cutter, and the paper on the bottom cutter roller 191 can be cut at intervals by pressing it onto the bottom cutter roller 191 under rotational pressure.

[0074] Process 7500 Paper conveying: The paper conveying device 23 uses the active roller 231 and the rubber pressure roller 232 to press the paper and convey it under tension, and then conveys the paper to the rack 241 of the folding device 24.

[0075] Process 8500 Folding: The paper coming out of the rack 241 is folded towards the spiral folders 242 on both sides by the reciprocating swing of the rack 241. The spiral folders 242 fold the paper down along the folding line by spiral rotation and fall onto the stacking conveyor 21.

[0076] Process 9000: Stacking Conveying: The folded product that falls onto the stacking conveyor 21 continues to be conveyed backward on the stacking conveyor 21. The speed of the stacking conveyor 21 is set to be significantly lower than the speed of the paper pressing conveyor 18, so that the folded finished product 5 can be slightly offset on the stacking conveyor 21 and continuously conveyed backward.

[0077] Step 9510 Paper Collection: The folded finished product 5 is caught on the table surface of the vibrating paper collection table 22 and stacked neatly. At this time, the vibration power of the vibrating paper collection table 22 needs to be turned off. Since the folded finished product 5 is folded along the fold line, it can be stacked neatly without vibration after falling on the table surface of the vibrating paper collection table 22.

[0078] As attached Figure 9 The process flow shown in step four describes a method for producing folded printing paper. Based on process flow three, after the correction step in step 2000 and before the collating step in step 3000, the following additional steps are performed:

[0079] Process 2500 Printing: The printer head 121 is controlled by computer 995 to print the preset graphics on the paper. The printer head 121 can be a color inkjet print head, which can produce color and black and white graphic products.

[0080] In the process flow 3 and 4 of the above embodiment, in the 7010 step of cutting the folding line, the specific method for cutting the folding line according to the designed length of each finished product is as follows: the encoder 993 feeds back the rotation speed of the bottom blade roller 191 to the controller 991. The controller 991 calculates the linear speed of the paper running based on the received rotation speed signal and the diameter of the bottom blade roller 191. Then, based on the length of each finished product preset on the touch screen 992 and the rotation diameter of the blade 192 on the blade roller 193, it calculates the rotation speed of the blade roller 193. The controller feeds back and controls the servo motor 994 to drive the blade roller 193 to rotate at the obtained rotation speed, so that the blade 192 presses against the bottom blade roller 191 through rotational pressure to cut the folding line on the paper according to the designed length. This method changes the traditional technical solution of using different diameter cutting rollers to control the cutting length, solves the problem of having to replace the cutting rollers when changing length specifications, and allows the length to be set arbitrarily within the range of 120mm to 500mm without being limited by transmission gears. Moreover, the dimensional accuracy of the cutting length can reach 0.1mm, which meets and exceeds the product size deviation standard of ±0.5mm.

[0081] In addition to the above embodiments, the process flow can be modified according to different changes in the product required by the customer. For example, the pressing and locking process is not required when producing single-layer products, and the process of cutting the longitudinal easy-tear line is eliminated when producing products that do not require tearing.

[0082] The technical solution described in this patent uses common materials, is suitable for industrial production, and is feasible and practical.
