Abstract
Description
Technical Field
[0002] This invention belongs to the field of calendar production equipment technology, and relates to a calendar production line. Background Technology
[0004] A calendar is a printed publication that displays information about a day on each page. It mainly records information such as year, month, day, week, solar terms, and holidays, and is widely used in people's daily lives.
[0005] like Figure 1 As shown, most calendars currently on the market are manufactured using traditional methods. This involves first cutting large sheets of paper and creating large sheets for the days of the year. Each large sheet is then composed of multiple smaller sheets for the same day. A certain number of these large sheets are printed, and then they are stacked sequentially. The stacks are then trimmed to create single-page stacks, which are finally bound together. Because this process requires at least 365 or 366 large sheets, the plate-making cost is high. Furthermore, the need to print such a large number of different sheets makes it impossible to integrate the entire production process into an automated assembly line. Each sheet must be printed individually, and then manually selected and stacked one by one for cutting. This entire production process requires significant space, has low efficiency, and is highly susceptible to errors such as misplaced or missing pages due to worker negligence, demanding high levels of manual skill. Summary of the Invention
[0007] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a calendar production line. The technical problem this invention aims to solve is: how to achieve automated calendar production.
[0008] The objective of this invention can be achieved through the following technical solution: a calendar production line, characterized in that it includes: an unwinding mechanism for outputting paper tape;
[0009] A transfer printing mechanism used for printing on paper tape;
[0010] The first production line is used to receive the printed paper tape and transport it backward. Along the transport direction, the first production line is provided with a slitting mechanism for cutting the paper tape into large sheets of paper, a staggered stacking mechanism for stacking the large sheets of paper into large sheets of paper and transporting them backward intermittently, and a first cutting mechanism for cutting the large sheets of paper into long strips of paper.
[0011] The second production line is located at the end of the first production line and is used to receive long strips of paper, so that the long strips of paper are stacked in a staggered manner and conveyed intermittently. The second production line is equipped with a second cutting mechanism for cutting the staggered stacks of long strips of paper into single sheets of paper.
[0012] This invention employs a fully automated production line design. First, the paper tape is printed. Then, according to the size of the printing plate, the paper tape is cut into large sheets of paper. The large sheets of paper are then stacked into a series of staggered stacks. The large sheets of paper are then cut into long strips of paper, which are then stacked in a staggered manner. Finally, they are cut into single-page stacks of paper the size of a calendar page, ready for binding. The entire production process is continuous and smooth, stable and reliable, and has higher production efficiency.
[0013] In the aforementioned calendar production line, there are multiple unwinding mechanisms and one-to-one correspondences between them. The paper tapes output by the unwinding mechanisms are printed by the corresponding transfer mechanisms, stacked one on top of the other, and then enter the first production line. In this way, the unwinding mechanisms and transfer mechanisms are connected in series in a one-to-one correspondence, and the groups form a parallel structure, which can improve production efficiency and reduce the size requirements of the paper rolls and printing plates in the transfer mechanisms, thus facilitating manufacturing and installation.
[0014] In the aforementioned calendar production line, the transfer mechanism has several printing rollers, including a front printing roller for printing the front side and a back printing roller for printing the back side, so as to print on both the front and back sides of the paper tape.
[0015] In the aforementioned calendar production line, the first conveyor line includes a first conveyor section and a second conveyor section arranged sequentially along its length. The first conveyor section includes an upper conveyor belt and a lower conveyor belt arranged vertically along the length of the first conveyor line, forming a conveying channel for large sheets of paper to pass through. The second conveyor section includes a horizontally arranged conveyor table located below the conveying channel. The first conveyor section provides the power to convey large sheets of paper to the second conveyor section through the upper and lower conveyor belts working in tandem. However, the conveyor table of the second conveyor section itself does not have the power to convey large sheets of paper backward. Furthermore, due to the height difference between the second conveyor table and the conveying channel of the first conveyor section, large sheets of paper stack on the conveyor table.
[0016] In the aforementioned calendar production line, the staggered stacking mechanism includes a movable frame, a baffle, a translation drive mechanism, and a lifting drive mechanism. The movable frame is movably disposed below the conveyor table. The translation drive mechanism is used to drive the movable frame to reciprocate along the conveyor table. The baffle is movably connected to the movable frame and is horizontally disposed above the conveyor table. The lifting drive mechanism is used to drive the baffle to move up and down relative to the movable frame. After the baffle moves down relative to the movable frame, it can cooperate with the movable frame to form a clamp, and the front end of the baffle can abut against the large sheet of paper conveyed by the first conveyor section. Before a new sheet of paper enters the conveyor table, the moving frame first moves the baffle forward, then the baffle moves down and works in conjunction with the moving frame to clamp and fix the stacked sheets of paper on the conveyor table. When the front end of the new sheet of paper enters the conveyor table and stacks on top of the sheets of paper on the conveyor table, the moving frame moves the stacked sheets of paper backward by a calendar page distance and stops. Then, the new sheet of paper is pushed into the second conveyor section by the first conveyor section and its front end abuts against the front end of the baffle, ensuring that the adjacent sheets of paper are staggered by a calendar page distance after stacking. Then the baffle moves up and moves forward again with the moving frame. This cycle repeats, so that the staggered stacked sheets of paper are intermittently conveyed in the second conveyor section.
[0017] In the aforementioned calendar production line, a pre-knife pressing mechanism is also provided between the staggered stacking mechanism and the first cutting mechanism. The pre-knife pressing mechanism includes a pressure plate located above the conveyor table and a pressing drive mechanism for driving the pressure plate to move up and down. The pre-knife pressing mechanism can press down and fix the large sheet of paper after the staggered stacking mechanism has conveyed it, so that the large sheet of paper can still maintain a stable fit after the staggered stacking mechanism is released.
[0018] In the aforementioned calendar production line, the rearward end of the upper conveyor belt extends to the rear side of the staggered stacking mechanism. A blowing assembly is located on the front side of the conveyor table, used to blow air onto the conveyor table and push the large sheets of paper upwards. The blowing assembly blows air onto the conveyor table, allowing the air to support the lower surface of the large sheets of paper as they enter the conveyor table, ensuring that the upper surface of the large sheets of paper contacts and engages with the upper conveyor belt, thus guaranteeing the stable transport of the large sheets of paper to the front of the baffle to form a staggered stack.
[0019] In the aforementioned calendar production line, the lower side of the upper conveyor belt is inclined downward along the conveying direction of the first production line. This allows the large sheets of paper to maintain a certain contact with the upper conveyor belt even after they are far away from the blowing assembly, making the conveying more stable and smooth.
[0020] In the aforementioned calendar production line, the second production line is arranged transversely relative to the first production line. The second production line has a conveyor belt, with positioning plates and alignment mechanisms on both sides. The positioning plates are elongated strips arranged along the length of the conveyor belt. The alignment mechanism includes a pusher plate and a transverse drive mechanism, which drives the pusher plate to reciprocate relative to the positioning plates. After the elongated paper stack enters the conveyor belt, the alignment mechanism pushes the side of the elongated paper stack, causing it to abut against the positioning plate on the other side, thus ensuring the neatness of the elongated paper stack.
[0021] In the aforementioned calendar production line, a post-knife paper pressing mechanism is provided on the rear side of the gantry suspension. This mechanism includes a translation component and several paper pressing components. Each paper pressing component includes a pressing block and a lifting drive for driving the pressing block up and down. The translation component includes a mounting frame fixed relative to the gantry suspension, a slide rod slidably mounted on the mounting frame along the conveying direction of the second production line, and a translation drive for driving the slide rod to reciprocate along the conveying direction of the second production line. The paper pressing components are spaced apart along the length of the slide rod and located directly above the second production line. The post-knife paper pressing mechanism can cooperate with the first cutting mechanism to press and fix large sheets of paper before cutting, and can also continue to press and fix long strips of paper after cutting, and can cooperate with the intermittent conveying of long strips of paper by the second production line.
[0022] Compared with the prior art, the present invention has the following advantages:
[0023] 1. This invention adopts a brand-new process flow design, which enables the paper tape to go through unwinding, printing, slitting into large sheets of paper, staggered stacking, cross-cutting into long strips of paper, staggered stacking, and longitudinal cutting into single sheets of paper ready for binding. The entire process is fully automated, the production process is continuous and smooth, the operation is stable and reliable, and the production efficiency is higher.
[0024] 2. This invention achieves the connection between the first and second conveyor sections by using an upper conveyor belt and a blowing assembly to transport large sheets of paper. The design is ingenious and the transport of large sheets of paper is more stable. Attached Figure Description

[0048] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0049] Example 1
[0050] A calendar production line, such as Figure 2 As shown, the production line includes an unwinding mechanism 1, a transfer printing mechanism 2, a first production line 3, and a second production line 4 arranged sequentially along the production line. The unwinding mechanism 1 outputs paper tape 51 backwards, the transfer printing mechanism 2 prints on the paper tape 51, the first production line 3 receives the printed paper tape 51 and conveys it backwards, and the first production line 3 is equipped with a slitting mechanism 32, a staggered stacking mechanism 37, and a first cutting mechanism 39 arranged sequentially along the conveying direction. The second production line 4 is located at the end of the first production line 3, and the second production line... The water line 4 is equipped with a second cutting mechanism 44, so that the paper tape 51 output by the unwinding mechanism 1 is printed by the transfer mechanism 2 and enters the first production line 3. It is then cut into large sheets of paper by the slitting mechanism 32, and then stacked in a staggered manner by the staggered stacking mechanism 37. It is then cut into long strips of paper 53 by the first cutting mechanism 39. The long strips of paper 53 then enter the second production line 4 and are stacked in a staggered manner. They are then cut into single-page stacks of paper 54 by the second cutting mechanism 44, ready to be bound into a calendar, thus realizing full automation of the process.
[0051] Specifically, such as Figures 2-4As shown, the unwinding mechanism 1 is rotatably equipped with a large paper tube formed by winding paper tape 51. The transfer mechanism 2 is located behind the unwinding mechanism 1 and contains several printing rollers 21. Each printing roller 21 has a large plate arranged circumferentially, and the large plate is composed of several small plates arranged in a square matrix. The small plates are printing plates for calendar pages. In this embodiment, there are three printing rollers 21, including two front printing rollers and one back printing roller. The two front printing rollers use red and green ink respectively for two-color printing on the front of the paper tape 51, and the back printing roller uses black ink for single-color printing on the back of the paper tape 51. When the paper tape 51 output from the unwinding mechanism 1 passes through the transfer mechanism 2, it can sequentially contact the three printing rollers 21 to complete the printing on the front and back of the paper tape 51. In this embodiment, the front of the calendar page mainly prints the date, day of the week, solar terms, holidays, and other main information, while the back can print life tips, popular science knowledge, and other information.
[0052] In this embodiment, there are three unwinding mechanisms 1, which are arranged sequentially along the length of the production line. Correspondingly, there are also three transfer printing mechanisms 2, which correspond one-to-one with the three unwinding mechanisms 1. The three unwinding mechanisms 1 are located behind the three unwinding mechanisms 1 and are arranged sequentially along the length of the production line. In this embodiment, the paper tapes 51 output by the three unwinding mechanisms 1 all enter the transfer printing mechanism 2 from below, and all exit from above the transfer printing mechanism 2 and converge, forming a stack and entering the first production line 3 simultaneously.
[0053] Of course, the unwinding mechanism 1 and the transfer mechanism 2 can also be arranged in pairs first, and then arranged sequentially along the production line.
[0054] like Figure 2 , Figure 7 As shown, the first production line 3 is located behind the transfer mechanism 2 and is arranged in the same direction as the production line. The first production line 3 includes a first conveying section and a second conveying section. A conveying roller group 31 is arranged at the front of the first conveying section. The conveying roller group 31 includes two conveying rollers that are arranged vertically and vertically. The two conveying rollers are synchronously engaged by gears and connected to a drive motor, so that the paper strip 51 can pass between the two conveying rollers and move towards the first conveying section with the cooperation of the two conveying rollers. The slitting mechanism 32 is arranged between the conveying roller group 31 and the first conveying section. In this embodiment, the slitting mechanism 32 adopts a motor-driven roller cutter. The roller cutter is rotatably arranged above the paper strip 51 and contacts the paper strip 51. By driving the roller cutter to rotate, the paper strip 51 is slid into large sheets of paper. To ensure the continuity of conveying, the distance between the conveying roller group 31 and the first conveying section should be less than the length of the large sheets of paper.
[0055] like Figures 5-7As shown, in this embodiment, the first conveying section includes a lower conveyor belt 331 arranged along the length direction of the first conveying section and an upper conveyor belt 332 located above the lower conveyor belt 331, so that a conveying channel 3a is formed between the upper side of the lower conveyor belt 331 and the lower side of the upper conveyor belt 332. The lower conveyor belt 331 and the upper conveyor belt 332 are driven by the same motor, so that the upper conveyor belt 332 and the lower conveyor belt 331 are kept synchronized. After the printed large sheet of paper enters the conveying channel 3a, it can be stably conveyed to the second conveying section under the clamping of the upper conveyor belt 332 and the lower conveyor belt 331.
[0056] The second conveying section includes a conveying table 34, which is a horizontally placed long strip. The height of the conveying table 34 is slightly lower than that of the conveying channel 3a and is adjacent to the conveying channel 3a, so that the large sheets of paper entering the second conveying section are stacked on the conveying table 34.
[0057] Furthermore, to prevent the large sheets of paper from sticking together during continuous transport, a separation mechanism 36 is provided between the first and second transport sections. The separation mechanism 36 includes a rotating shaft 361 and a drive motor for driving the rotating shaft 361 to rotate. The rotating shaft 361 is mounted above the transport table 34 along the width direction. Several eccentrically arranged dials 362 are spaced along the length direction on the rotating shaft 361. When the tail of the large sheet of paper reaches below the dial 362, the drive motor can drive the dial 362 to rotate, so that the end of the dial 362 farther from the rotation center contacts and abuts against the tail of the large sheet of paper, and moves the large sheet of paper to ensure that adjacent large sheets of paper are completely separated for stacking.
[0058] like Figures 7-10As shown, the staggered stacking mechanism 37 is located in the second conveying section and includes a movable frame 371, a baffle 373, a translation drive mechanism 374, and a lifting drive mechanism. Two guide rods are arranged below the conveying table 34 along the length direction of the conveying table 34 and spaced apart along the width direction of the conveying table 34. The movable frame 371 is slidably engaged with the two guide rods. The translation drive mechanism 374 includes a transmission belt assembly arranged along the length direction of the guide rods and a drive motor for driving the transmission belt assembly. The transmission belt assembly is located below the movable frame 371, and the movable frame 371 is connected to the upper transmission belt through a connector, so that the drive motor can drive the movable frame 371 to reciprocate along the length direction of the guide rods. The baffle 373 is elongated and located above the conveyor table 34. Both ends of the baffle 373 are slidably connected to the movable frame 371. A lifting drive mechanism is provided between both ends of the baffle 373 and the movable frame 371 to drive the baffle 373 to move up and down relative to the movable frame 371, so that the baffle 373 and the movable frame 371 cooperate to clamp the large sheet of paper 52. In this embodiment, the lifting drive mechanism is a cylinder. Through the cooperation of the translation drive mechanism 374 and the lifting drive mechanism, this staggered stacking mechanism 37 can intermittently clamp the stacked large sheet of paper 52 and convey it towards the first cutting mechanism 39. After the baffle 373 moves down, its front end can abut against the newly conveyed large sheet of paper on the conveyor table 34, ensuring that the newly conveyed large sheet of paper forms a precise staggered stack with the large sheet of paper below.
[0059] To ensure that the movable frame 371 and the baffle 373 cooperate while avoiding interference with the conveyor table 34, in this embodiment, the rear end of the conveyor table 34 is provided with several clearance grooves 34a arranged along the length direction. The clearance grooves 34a are spaced apart along the width direction of the conveyor table 34. Correspondingly, the movable frame 371 has several slides 372, all of which are arranged along the length direction of the conveyor table 34. The number of slides 372 is the same as that of clearance grooves 34a and they correspond one-to-one. The slides 372 are respectively embedded in the corresponding clearance grooves 34a and can move back and forth along the length direction of the clearance grooves 34a. The upper surface of the slide 372 is a smooth plane. After the slide 372 is embedded in the clearance groove 34a, the upper surface of the slide 372 is basically flush with the conveyor table 34 so as to form a clamping fit with the pressure plate.
[0060] like Figure 7As shown, in this embodiment, the rearward end of the upper conveyor belt 332 extends to the rear side of the staggered stacking mechanism 37. A blower assembly 35 for supplying air to the conveyor table 34 is also provided on the front side of the conveyor table. The blower assembly 35 can be a blower or a nozzle connected to an air source, creating a certain air pressure on the lower surface of the large sheet of paper entering the conveyor table 34 and pushing the large sheet of paper upwards. This causes the large sheet of paper to contact the upper conveyor belt 332 extending above the conveyor table 34, facilitating the upper conveyor belt 332 to continue providing power and moving the large sheet of paper towards the staggered stacking mechanism 37. Furthermore, since the air pressure decreases with distance from the blower assembly 35, once the large sheet of paper comes into contact with the baffle 373, there is essentially no longer contact between the large sheet of paper and the upper conveyor belt 332. The large sheet of paper can then stably stop in front of the baffle 373 and form a staggered stack with the large sheet of paper below.
[0061] Furthermore, such as Figure 10 As shown, the movable frame 371 is also equipped with a guide roller. The guide roller is located in front of the baffle 373 and is mounted above the conveyor table 34 along the width direction of the conveyor table 34. The lower side of the upper conveyor belt 332 passes under the guide roller and abuts against the guide roller, so that the lower side of the upper conveyor belt 332 is slightly inclined downward along the conveying direction of the first assembly line 3, with an inclination angle of about 1°. The lower end face of the baffle 373 has several clearance grooves 373a, which are distributed at intervals along the length direction of the baffle 373. The width of the clearance grooves 373a is slightly larger than the width of the upper conveyor belt 332, so that the upper conveyor belt 332 can pass through the clearance grooves 373a and extend to the rear side of the staggered stacking mechanism 37, avoiding interference.
[0062] Furthermore, a front-knife pressing mechanism 38 is provided between the staggered stacking mechanism 37 and the first cutting mechanism 39 for cooperating with the staggered stacking mechanism 37. The front-knife pressing mechanism 38 includes a pressure plate and a downward pressing drive mechanism. The pressure plate is located above the conveying table 34, and the lower end surface of the pressure plate is a smooth plane. The downward pressing drive mechanism can drive the pressure plate to move up and down. After the staggered stacking mechanism 37 clamps the stacked large sheet of paper 52 and conveys it to the rear position, the front-knife pressing mechanism 38 can take over from the staggered stacking mechanism 37 and continue to press the large sheet of paper 52.
[0063] like Figure 9 , Figure 13 As shown, the first cutting mechanism 39 is located at the tail of the first production line 3, and includes a gantry suspension 391, a first cutter 392, two eccentric shafts 393, and a drive motor. The gantry suspension 391 is mounted above the conveyor table 34 and has two spaced-apart crossbeams 3911. The first cutter 392 is laterally movable within the gap between the two crossbeams 3911 via the two eccentric shafts 393. Specifically, as... Figure 12As shown, the eccentric shaft 393 includes a shaft body 3931 and an eccentric wheel 3932. The shaft body 3931 is elongated, and the eccentric wheel 3932 is disc-shaped. The eccentric wheel 3932 is located in the middle of the shaft body 3931 and is eccentrically positioned relative to the shaft body 3931. Both eccentric shafts 393 are mounted between two crossbeams 3911, and both ends of the shaft body 3931 are rotatably connected to the two crossbeams 3911. Both ends of the first cutter 392 are rotatably connected to the eccentric wheel 3932 of the two eccentric shafts 393, and there is a certain angle difference between the eccentric wheel 3932 of the two eccentric shafts 393. The drive motor is connected to the shaft body 3931 of the two eccentric shafts 393 through chain drive or gear drive, so that the drive motor can drive the first cutter 392 to perform up-and-down twisting cutting motion relative to the large stack of paper 52 below.
[0064] Furthermore, such as Figure 11 As shown, to ensure the stability of the large sheet of paper 52 during cutting, a cutter pressing mechanism 394 and a rear-cutter pressing mechanism 395 are respectively provided on the front and rear sides of the gantry suspension 391, so that the first cutter 392 is located between the cutter pressing mechanism 394 and the rear-cutter pressing mechanism 395. In this embodiment, the structure of the cutter pressing mechanism 394 is basically the same as that of the front-cutter pressing mechanism 38, both including a pressing block and a lifting drive component that drives the pressing block to move up and down. The lifting drive component drives the pressing block to move up and down so that the cutter pressing mechanism 394 and the rear-cutter pressing mechanism 395 press the front and rear sides of the large sheet of paper 52 to be cut tightly before cutting. The lifting drive component is usually a pneumatic cylinder, an electric cylinder, or a hydraulic cylinder. In this embodiment, the lifting drive component is a hydraulic cylinder.
[0065] Furthermore, in this embodiment, the paper pressing mechanism 395 after the knife includes a translation component 3951 and a plurality of pressing components 3952. The pressing component 3952 includes a pressing block and a lifting drive for driving the pressing block to move up and down. The translation component 3951 includes a mounting frame, a slide rod, and a translation drive. The mounting frame is fixedly installed on the side of the gantry suspension 391 near the second production line 4. The slide rod is slidably disposed on the mounting frame along the conveying direction of the second production line 4. The pressing components 3952 are spaced apart on the slide rod along the length direction of the slide rod and are located directly above the second production line 4. The translation drive is connected to one end of the slide rod and can drive the slide rod to reciprocate along the conveying direction of the second production line 4. In this way, before cutting, the tail of the large paper stack 52 is directly fixed to the conveyor belt of the second production line 4 through the paper pressing mechanism 395 after the cutter, so that the cut long paper stack 53 is directly formed on the second production line 4. Moreover, under the drive of the translation drive, when the second production line 4 is conveying intermittently, the pressing component 3952 can maintain the pressing state and move synchronously with the long paper stack 53, and can move backward to reset after the second production line 4 stops conveying. This cycle is repeated to ensure the smooth conveying of the long paper stack 53.
[0066] like Figure 6 , Figure 13 As shown, the second production line 4 uses a conveyor belt 41 for conveying. The conveyor belt 41 is set along the length of the second production line 4. The height of the conveyor belt 41 is slightly lower than the conveyor table 34. The conveyor belt 41 is set horizontally below the first cutting mechanism 39 relative to the conveyor table 34. By controlling the drive motor of the conveyor belt 41, the conveyor belt 41 can achieve intermittent conveying. That is, every time the first cutting mechanism 39 cuts, the conveyor belt 41 feeds a certain distance, so that the long strip paper stack 53 forms a continuous staggered stack. The staggered stack of long strip paper stack 53 is conveyed to the second cutting mechanism 44 for cutting. The long strip paper stack 53 is cut into a single-page stack 54 containing a year's calendar pages.
[0067] Furthermore, in this embodiment, the second production line 4 is provided with a positioning plate 42 and an alignment mechanism 43 on both sides of the conveyor belt 41. The positioning plate 42 is in the shape of a long strip, and the alignment mechanism 43 is located on the other side of the conveyor belt 41. It includes a push plate 431 and a transverse drive mechanism 432 for driving the push plate 431 to move back and forth relative to the positioning plate 42. The long strip of paper 53 formed after being cut by the first cutting mechanism 39 can fall between the positioning plate 42 and the push plate 431. By driving the push plate 431 to laterally squeeze the long strip of paper 53 and make the long strip of paper 53 fit against the side wall of the positioning plate 42, the long strip of paper 53 is kept neat.
[0068] Furthermore, in order to ensure the neatness of the long strip paper stack 53 when the second cutting mechanism 44 cuts it, a similar cutter pressing mechanism 394 is also provided on the front side of the second cutting mechanism 44 in this embodiment.
[0069] like Figures 14-16 As shown, in this embodiment, the large plates of the front plate rollers on the three transfer mechanisms 2 respectively correspond to... Figures 14-16That is, all the single-page small sheets on the front of the entire calendar are distributed in the three large sheets of the three transfer units 2. Each large sheet is the same size and is arranged in a square matrix of 11 rows and 12 columns, so that the total number of small sheets is greater than the total number of days in a year. The small sheets in each large sheet are sorted according to n=x+33(y-1)+3(z-1), where n is the page number of the corresponding single-page small sheet in the entire calendar, x is the corresponding large sheet number, y is the column number from right to left in the corresponding large sheet, and z is the row number from bottom to top in the corresponding large sheet. For example, if the first small page in the bottom right corner of the first large page has x=1, y=1, z=1, then n=1+33×(1-1)+3×(1-1)=1, meaning this small page corresponds to the first page of the entire calendar, with the date January 1st. Similarly, if the small page corresponding to the third column and fourth row of the second large page has x=2, y=3, z=4, then n=2+33×(3-1)+3×(4-1)=77, meaning this small page corresponds to the 77th page of the entire calendar, with the date March 18th. In this embodiment, if n is greater than the total number of days in a year, then the single-page small page uses a notepad page to maintain consistency in the layout of the small pages across the large pages.
[0070] like Figures 14-18 As shown, the working process of this invention is as follows: three unwinding mechanisms 1 respectively output paper tapes 51 to the corresponding transfer mechanisms 2 for printing. After printing, the three paper tapes 51 are stacked vertically and enter the first production line 3. They are then cut into three stacked large sheets of paper according to the large sheet size by the slitting mechanism 32. The stacked large sheets of paper are then continuously fed by the staggered stacking mechanism 37 to form a staggered stack of large sheets of paper 52, which is intermittently fed towards the first cutting mechanism 39. Each time the large sheet of paper 52 is fed, it is a small sheet along the longitudinal dimension, and each time it is fed... Each time, the first cutting mechanism 39 makes a horizontal cut and forms a long strip of paper on the second production line 4. Each time the first cutting mechanism 39 makes a cut, the horizontally arranged second production line 4 drives the long strip of paper to be intermittently transported by a distance equal to the horizontal dimension of each small plate, so that the long strips of paper on the second production line 4 are stacked in a staggered manner and pass through the second cutting mechanism 44. Each time the second production line 4 is intermittently transported, the second cutting mechanism 44 cuts the long strip of paper once in the longitudinal direction and forms a single-page paper stack 54 of single-page calendar-sized sheets, which are stacked in sequence for subsequent binding processing.
[0071] Example 2
[0072] like Figure 19 As shown, the technical solution of this embodiment is basically the same as that of embodiment one. The difference is that in this embodiment, there are four unwinding mechanisms 1 and four transfer mechanisms 2, which correspond one-to-one. All the small sheets required for the whole calendar are distributed in the four transfer mechanisms 2. After the paper tape 51 is cut by the cutting mechanism 32, it forms four large sheets of paper stacked in sequence. The four large sheets of paper contain all the pages of the whole calendar.
[0073] Example 3
[0074] like Figure 20 As shown, the technical solution of this embodiment is basically the same as that of Embodiment 1. The difference is that in this embodiment, the unwinding mechanism 1 and the transfer mechanism 2 are both one, so that all the small sheets required for the whole calendar are arranged in the same transfer mechanism 2. That is, each large sheet of paper after cutting contains all the pages of the whole calendar.
