At least part of the arc-shaped peripheral wall of the paper suction roller protrudes outward from the air suction opening.
[0016] In one embodiment, the second conveying unit further includes a first motor, which is mounted on the paper feeding table and connected to the suction roller to drive the suction roller to rotate.
[0017] In one embodiment, the housing is provided with a guide shaft portion extending in the vertical direction, and one end of the paper feeding table is slidably mounted on the guide shaft portion;

[0043] Sheet-fed presses are one of the core pieces of equipment in the modern printing industry, especially dominating commercial printing, packaging printing, and high-end printing. The technological background of sheet-fed presses is the result of the high integration and continuous innovation of precision mechanical engineering, fluid mechanics (ink-water balance), materials science, automatic control, sensor technology, computer technology (digital workflow), and optical technology (color management). Its core objectives are to pursue higher print quality, faster production efficiency, shorter start-up time, wider material adaptability, lower scrap rates and operating costs, greater automation and intelligence, and better environmental and safety performance. Continuous technological advancements, such as shaftless drives, closed-loop color control, inline processing, and hybrid printing, are constantly driving sheet-fed presses towards greater efficiency, intelligence, and versatility. Current technological problems include: Modern digital sheet-fed presses use a mechanical structure with left-right paper shifting during paper feeding. When paper shifting is required, the machine needs to slow down to ensure the mechanical structure is in place without disrupting the paper. This structure wastes a significant amount of time when printing small batches of documents.
[0044] This invention proposes a paper receiving structure to solve the above problems.
[0045] Please see Figures 1 to 2 and Figure 5 In one embodiment of this utility model, the paper receiving structure 100 includes a housing 1, a paper feeding structure 2, and a misaligned book structure 4. The housing 1 has a paper feeding platform 3 on its inner side, and the paper feeding platform 3 has a vertical travel distance on the housing 1. The paper feeding structure 2 includes a first conveying part 21 and a second conveying part 22, which together form a paper feeding path on the paper feeding platform 3. The first conveying part 21 is disposed at one end of the paper feeding platform 3 to transfer paper onto the paper feeding platform 3. The second conveying part 22 is mounted on the housing 1 above the paper feeding platform 3 to absorb paper upwards and convey the paper along the paper feeding path. The misaligned book structure 4 is disposed on the housing 1 above the paper feeding platform 3, and the misaligned book structure 4 includes at least two paper blocking parts, which are spaced apart on the paper feeding path.
[0046] The structure described in the above embodiment is mainly applied to the paper collection operation after printing. The first conveying unit 21 serves as an intermediate connecting structure between the entire paper collection structure 100 and the front-end printing structure. It can convey the printed paper to the paper feed table 3. The coordinated operation of the first conveying unit 21 and the second conveying unit 22 can move the paper from one end of the paper feed table 3 to the side of the paper stop. The above paper feeding process corresponds to the paper feeding path on the paper feed table 3.
[0047] Specifically, the above structure allows for the continuous printing of multiple books and documents. After one book is printed, the misprint structure 4 automatically misprints it, thus preventing two books from accumulating vertically and becoming indistinguishable. Specifically, when the paper moves onto the second conveyor section 22, the second conveyor section 22 not only moves the paper towards the paper stop but also simultaneously picks up the paper, lifting one end of the paper. This avoids interference between two adjacent sheets of paper on the paper feed path, which is the structural basis for multiple sheets of paper to be accumulated on the side of the paper stop.
[0048] Both paper stop sections are located on one side of the second conveyor section 22 along the paper feeding path to limit and block the paper, thereby causing multiple sheets of paper to accumulate on one side of the paper stop section. It should be noted that the downward extension lengths of the two paper stop sections in the vertical direction differ, with the downward extension lengths increasing progressively from the first conveyor section 21 to the second conveyor section 22. Specifically, during paper collection, the paper stop section furthest from the paper feeding structure 2 is used to block the paper initially. When the paper accumulates to a certain extent vertically, or when the same sheet of paper is printed, the paper feed table 3 can move downwards a short distance vertically. At this point, the paper stop section closest to the second conveyor section 22 can continue to block the paper, allowing the paper to continue accumulating through the first conveyor section 21 and the second conveyor section 22.
[0049] It should be noted that the movement of the paper receiving table, the first conveying unit 21, and the second conveying unit 22 are all synchronized. During the switching of the paper stop, the entire paper receiving operation is uninterrupted and can continue continuously. Furthermore, because the two paper stopes are spaced apart on the paper receiving path, switching the paper stopes during paper receiving can prevent misalignment between two types of paper or two sets of paper, avoiding the accumulation of two printed documents that would make separation difficult later.
[0050] The error book structure 4 further includes a structure base body 41, which is fixedly installed on the upward end of the outer shell 1; at least one of the two paper-blocking parts is configured as a fixed paper-blocking part 42, which is fixedly installed on the side of the structure base body 41 away from the paper feeding structure 2, and the downward end of the fixed paper-blocking part 42 protrudes from the end of the structure base body 41.
[0051] Of the two paper stop sections, the one furthest from the paper feeding structure 2 is designated as a fixed paper stop section 42. During installation, the fixed paper stop section 42 is fixedly installed on the side of the structure base body 41 furthest from the paper feeding structure 2, with its downward-facing end protruding from the structure base body 41. As the paper moves along the paper feeding path towards the structure base body 41, it is blocked by the fixed paper stop section 42, allowing the paper to accumulate on one side of the fixed paper stop section 42.
[0052] As mentioned above, another paper stop is located near the paper feeding structure 2, specifically in front of the fixed paper stop 42 along the paper feeding path. During the paper-stopping process of the fixed paper stop 42, to minimize its impact on the fixed paper stop 42, it is preferable to configure another paper stop as a movable paper stop 43. The movable paper stop 43 is located on the structural base body 41 at the end of the fixed paper stop 42 near the paper feeding structure 2, and has a vertical travel distance on the structural base body 41.
[0053] The movable paper stop 43 includes two baffle sections 431, both of which are slidably mounted on the structural base body 41 in the vertical direction. A corresponding drive structure 44 is provided on the structural base body 41, connected to the two baffle sections 431 to drive them to move vertically. The drive structure 44 can be a linear drive structure, such as a cylinder and electric actuator, or a linkage structure, depending on the actual production conditions.
[0054] During the actual printing process, the drive structure 44 first drives the two baffle parts 431 to be housed within the structure base body 41. The lower end face of the fixed paper stop part 42 is basically in contact with the upper end face of the paper feed table 3. After the same paper document is printed, the program automatically controls the printing device to print the next paper document. During this process, the paper feed table 3 moves downward a certain distance synchronously, and at the same time, the drive structure 44 drives the two baffle parts 431 to extend downward from inside the structure base body 41, with their ends pressing down on the paper of the previous document. The paper conveyed from the paper delivery path will be blocked by the two baffle parts 431. This enables the printing of two documents without misprints. When the paper feed table 3 moves downward a certain distance, the operator can also directly remove the previously printed document from the paper feed table 3.
[0055] Specifically, the structural base body 41 is installed at the upper end of the outer shell 1. A mounting bracket portion 11 is provided on the upward-facing end of the outer shell 1. The mounting bracket portion 11 includes at least two through rods 111, and the structural base body 41 is installed on the two through rods 111. The structural base body 41 has through holes 411. During installation, the two through rods 111 are respectively inserted into the two through holes 411. For actual fixing, clamping plates can be provided on both sides of the structural base body 41, and bolts or other structures can be used to fix the structural base body 41 to the fixed positions on the through rods 111.
[0056] The second conveying unit 22 includes a paper suction roller 221 and an air suction device 222. The paper suction roller 221 is rotatably mounted on the paper feeding table 3 corresponding to the paper feeding path. An air suction chamber is formed on the inner side of the paper suction roller 221. The two ends of the air suction chamber pass through the two ends of the paper suction roller 221 in the axial direction, and a plurality of suction holes 2212 are provided on the arc-shaped peripheral wall of the paper suction roller 221. The air suction device 222 is mounted on the paper feeding table 3, and one end of the air suction device 222 is connected to one end of the air suction chamber.
[0057] Specifically, the paper feeding table 3 is provided with two right-angled plate portions 31. The two ends of the suction roller 221 are rotatably mounted on the two right-angled plate portions 31 respectively. The suction device 222 is mounted on one of the right-angled plate portions 31, and one end of the suction device 222 is connected to the inner cavity of the suction chamber. A suction gap is formed between the paper feeding table 3 and the suction roller 221. When the suction device 222 is working, it can generate negative pressure in the suction chamber. When one end of the paper moves to the position of the suction gap, the multiple suction holes 2212 will suck one end of the paper upward. During the rotation of the suction roller 221, it can synchronously drive the paper towards the paper stop. In actual settings, the negative pressure suction force of the suction device 222 can be adjusted according to the overall weight of the paper to ensure that the suction roller 221 can feed the paper along the paper feeding path.
[0058] Considering that the suction roller 221 has a plurality of suction holes 2212 evenly provided on its peripheral wall, if the suction force is too large during the rotation of the suction roller 221, the paper may be rolled up on the arc-shaped outer wall of the suction roller 221, thereby affecting the paper conveying. Considering the above problems, in this embodiment, a shielding structure is provided at the outer peripheral wall of the suction roller 221. Specifically, the second conveying part 22 also includes an air blocking block 223, which is installed on the paper feeding table 3. The air blocking block 223 is provided with a mounting slot 2231. Both ends of the mounting slot 2231 in the length direction pass through the air blocking block 223. An air suction opening 2232 is formed on one side of the mounting slot 2231 corresponding to the paper feeding table 3. The suction roller 221 is disposed in the mounting slot 2231, and both ends of the suction roller 221 extend outward from both ends of the mounting slot 2231. At least part of the arc-shaped peripheral wall of the suction roller 221 protrudes outward from the air suction opening 2232.
[0059] like Figure 2 , Figure 3 and Figure 4 As shown, the air-blocking block 223 is also installed on the two right-angled plate portions 31, and the air intake opening 2232 is set corresponding to the paper suction gap. Specifically, the diameter of the mounting slot 2231 is set as close as possible to the arc-shaped outer wall of the suction roller, so that the suction force generated by the suction roller can be concentrated as much as possible at the positions of the multiple suction holes 2212 leaking outward from the air intake opening 2232. When the paper moves to the position below the air intake opening 2232, the paper suction roller 221 can suck one end of the paper upward through the multiple suction holes 2212, thereby avoiding interference between one end of the paper and one end of the previous paper. In addition, during the rotation of the paper suction roller 221, due to the air-blocking effect of the air-blocking block 223, it can effectively prevent one end of the paper from wrapping around the paper suction roller 221. During the rotation of the paper suction roller 221, it can ensure that the paper moves along the paper feeding path to one side of the paper stop portion.
[0060] The entire paper feeding structure 2 can achieve automated adjustment and control during actual operation. Specifically, the second conveying section 22 includes a first motor 224 to drive the suction roller 221 to rotate. The first motor 224 is mounted on the paper feeding table 3 and connected to the suction roller 221 to drive its rotation. During installation, the first motor 224 is mounted on one of the right-angle plate sections 31, and a belt structure is provided at the output end of the first motor 224, which is connected to one end of the suction roller 221.
[0061] In one embodiment of this solution, the outer casing 1 is provided with a guide shaft portion 51 extending in the vertical direction, and one end of the paper feeding table 3 is slidably mounted on the guide shaft portion 51; the paper receiving structure 100 further includes a height adjustment assembly 5, which includes a lead screw 52 and a second motor 53. The lead screw 52 is rotatably mounted on the outer casing 1 along an axis extending in the vertical direction, and the paper feeding table 3 and the lead screw 52 are threadedly engaged; the second motor 53 is mounted on the outer casing 1, and the output end of the second motor 53 is connected to the lead screw 52 to drive the lead screw 52 to rotate.
[0062] When the second motor 53 is working, it drives the lead screw 52 to rotate. During the rotation of the lead screw 52, it can drive the paper feeding table 3 to move in the vertical direction. During the movement of the paper feeding table 3, the guide shaft 51 can guide it, thereby ensuring the stability of the paper feeding table 3 in the vertical direction.
[0063] The above structure is a linear drive structure 44. In addition to the structure disclosed above, the drive structure 44 that drives the paper feeding table 3 can also be set as a pneumatic or hydraulic cylinder structure, or a linear motor structure, etc.
[0064] like Figure 2 and Figure 3 As shown, the first conveying unit 21 includes a receiving plate 211, a paper feeding roller 212, and a third motor 213. The receiving plate 211 is mounted on the outer casing 1 on one side corresponding to the paper feeding table 3; the paper feeding roller 212 is rotatably mounted on the outer casing 1 above the receiving plate 211; the third motor 213 is disposed on the outer casing 1 and is connected to the paper feeding roller 212 to drive the paper feeding roller 212 to rotate.
[0065] The paper is fed onto the receiving plate 211, and the third motor 213 drives the paper feeding roller 212 to rotate. When the paper moves to the position of the paper feeding roller 212, the paper feeding roller 212 can press down the paper and feed the paper onto the feeding plate.
[0066] To improve the paper feeding efficiency and effectiveness of the paper feeding structure 2, at least two paper feeding rollers 212 can be configured. These two rollers are arranged parallel to each other above the receiving plate 211. Using two rollers improves the contact between the rollers and the paper, and effectively increases the paper feeding stroke. Specifically, a third motor 213 can simultaneously drive both rollers 212 to rotate in the same direction. Both rollers 212 are rotatably mounted on the housing, and a belt structure connects them on the same side. A belt structure is also provided at the output end of the third motor 213, and this belt structure is also fitted onto one end of one of the rollers 212. When the third motor 213 operates, the two belt structures allow the two rollers 212 to rotate in the same direction, thus jointly delivering paper to the paper feeding table 3.
[0067] Another possibility is that the aforementioned mechanical structure can achieve fully automatic printing control by setting corresponding sensing devices and control structures. For example, corresponding sensing structures can be set on the outer casing 1 at the positions of the first conveying section 21 and the conveying section, allowing adjustment of the paper feeding speed of the two conveying structures based on the specific position of the previous sheet. Furthermore, a corresponding sensing device can be set on the right-angle plate section 31 to count the number of sheets in the same printout, or the number of sheets in the current printout can be input into the control structure. After the same printout is completed, the movable paper stop section 43 can be controlled to automatically switch paper stops. The above control process involves the circuit connection and program control of the sensing elements and control structures, which is achievable and will not be elaborated further here.
[0068] This utility model also includes a printer, which includes a paper feeding structure 2. The specific structure of the paper feeding structure 2 is as described in the above embodiments. Since the paper feeding structure 2 includes all the technical solutions in the above embodiments, the printer also has all the beneficial effects of the above embodiments, which will not be repeated here.
[0069] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
