Description

Technical Field

[0001] The present application relates to the technical field of printing equipment, and in particular to a shielding structure for preventing printing paper from being contaminated. Background Art

[0002] In the prior art, since some papers require multiple color information, a monochrome printing press is selected for printing for relatively simple texts and patterns. Since this type of printing press can only use one color of ink for printing at a time, in order to print multiple colors, there are multiple monochrome printing presses in one process, and each printing press is responsible for printing different colors. After the paper is printed in sequence by multiple monochrome printing presses, it can have multiple color information.

[0003] The paper between adjacent monochrome printing presses is usually provided with conveying rollers at the exit and entrance of the printing presses for conveying the paper. When the monochrome printing press is printing, the paper between the two printing presses may be splashed with ink spots, which affects the printing quality of the paper, and thus further improvement is needed. Utility Model Content

[0004] In order to reduce the possibility of ink dots splashing on paper, the present application provides a shielding structure to prevent the printed paper from being contaminated.

[0005] The present application provides a shielding structure for preventing printed paper from being contaminated, which adopts the following technical solution:

[0006] A shielding structure for preventing printed paper from being contaminated comprises a first baffle plate arranged between two adjacent printing presses and two fixing components for fixing the two ends of the first baffle plate to the printing presses on both sides, wherein the first baffle plate is arranged above the paper, and the size of the first baffle plate is larger than the size of the paper exposed to the printing press; the first baffle plate comprises two first plate bodies that slide against each other, a relatively sliding limiter is arranged between the two first plate bodies, and two fixing components are respectively arranged at the two ends of the first plate body that are far away from each other.

[0007] By adopting the above technical solution, a first baffle is arranged between two adjacent printing presses and arranged above the paper. Since the size of the first baffle is larger than the size of the paper exposed to the printing press, the paper is shielded to block the ink dots originally thrown onto the paper, so as to reduce the possibility of ink dots splashing on the paper and prevent the possibility of the printed paper being contaminated. And since the two first plates slide against each other, the size of the first baffle can be adjusted according to the distance between the two printing presses to improve the protection effect on the paper.

[0008] Preferably, a through groove is formed on the first plate body near the inlet of the printing press along its thickness direction for paper to pass through, and a second baffle is provided upwardly on the first plate body, and the second baffle includes a blocking portion installed with the first plate body and a mounting portion arranged between the blocking portion and the printing press.

[0009] By adopting the above technical solution, since the paper inlets of some printing presses are located at a relatively high position, the paper needs to be transported upward (the paper is in a continuous long strip shape), and the adjacent printing presses need to transport the paper from the lower paper outlet to the higher paper inlet. The first baffle set may hinder the moving direction of the paper. Therefore, a through groove for the paper to pass through is opened on the first plate body to transport the paper upward. For the part exposed on the first baffle, a second baffle is correspondingly arranged upward to cover the paper, thereby reducing the possibility of ink spots being thrown onto the exposed paper.

[0010] Preferably, the second baffle includes a second plate body and a third plate body in a direction away from the first baffle, the second plate body is the blocking part, the third plate body is the mounting part, the second plate body is rotated on the first plate body, the third plate body is rotatably connected to the second plate body, the second plate body includes two sliding plates arranged for relative sliding, a relative sliding limiter is also arranged between the two sliding plates, and a fixing component is also arranged on the third plate body for installation with the printing press.

[0011] By adopting the above technical solution, the second plate body includes two sliding plates that are relatively slidably arranged, so that the height of the second plate body can be adjusted according to the openings of different printing presses to adapt to the height positions of the inlets of different printing presses.

[0012] Preferably, the third plate body also includes two sliding plates arranged to slide relative to each other.

[0013] By adopting the above technical solution, when the second baffle is set on the first plate body without a through groove, when the width formed by the two first plates changes, there may be a gap between the third plate body in the second baffle and the printing press, which is inconvenient for the installation between the third plate body and the printing press. Therefore, the third plate body also includes two sliding plates that are relatively slidingly arranged to facilitate corresponding adjustments and changes, so as to improve the protective effect of the second baffle on the paper.

[0014] Preferably, the lower end of the second baffle is slidably connected to the first plate body, and the first plate body is provided with a limiting member for limiting the sliding of the second baffle.

[0015] By adopting the above technical solution, when the second baffle is set on the first plate body at the exit of the printing press, when the width formed by the two first plates changes, there may be a gap between the third plate body in the second baffle and the printing press, which is inconvenient for the installation between the third plate body and the printing press. Therefore, the second baffle is slidably connected to the first plate body to allow corresponding adjustments and changes to be made, so as to improve the protective effect of the second baffle on the paper.

[0016] Preferably, the first baffle is arranged at an angle, and a blocking portion for blocking ink dots is provided at the lower end of the first baffle.

[0017] By adopting the above technical solution, the first baffle is set at an angle so that the ink dots thrown on the first baffle flow along the inclination direction of the first baffle, reducing the possibility of overflowing from both sides of the first baffle to the outside when retained on the parallel first baffle. In order to reduce the possibility of excessive ink dots falling onto the paper along the lower end of the first baffle, a blocking portion for blocking the ink dots is provided at the lower end of the first baffle for blocking.

[0018] Preferably, an adsorption member for adsorbing ink dots is provided on the first baffle.

[0019] By adopting the above technical solution, an adsorbent is provided on the first baffle plate to adsorb ink dots, thereby reducing the possibility of ink flowing to both sides of the first baffle plate.

[0020] Preferably, an adsorption member for adsorbing ink dots is provided on the second baffle.

[0021] By adopting the above technical solution, since the second baffle is arranged upward, the ink dots may bounce back and splash to other positions, such as splashing onto paper, when they are thrown onto the blocking part in the second baffle. Therefore, an adsorbent is provided to reduce the possibility of the ink dots being thrown onto the paper.

[0022] In summary, the utility model has the following beneficial effects:

[0023] 1. A first baffle is provided between two adjacent printing presses and above the paper. Since the size of the first baffle is larger than the size of the paper exposed to the printing press, the paper is shielded to block the ink dots originally thrown onto the paper, thereby reducing the possibility of ink dots splashing on the paper and preventing the possibility of the printed paper being contaminated. Furthermore, since the two first plates slide against each other, the size of the first baffle can be adjusted according to the distance between the two printing presses to improve the protection effect on the paper.

[0024] 2. A through slot for paper to pass through is provided on the first plate body so that the paper can be transported upward. For the paper exposed on the first baffle, a second baffle is provided upward correspondingly to cover the paper, thereby reducing the possibility of ink spots being thrown onto the exposed paper.

[0031] The following is combined with Figure 1-5 , further details of this application are given.

[0032] The embodiment of the present application discloses a shielding structure for preventing printed paper from being contaminated.

[0033] Embodiment 1:

[0034] A shielding structure for preventing printed paper from being contaminated, referring to Figure 1 , Figure 2 , including a first baffle 2 arranged between two adjacent printing machines 1 and two fixing components 3 for fixing the two ends of the first baffle 2 to the printing machines 1 on both sides, wherein the first baffle 2 is arranged above the paper 11. It should be noted that the size of the first baffle 2 is larger than the size of the paper 11 exposed from the printing machine 1, and extends to both sides of the paper 11 to improve the protection of the paper 11.

[0035] It should be noted that since the height positions of the outlets 12 and inlets 13 between adjacent printing presses 1 are different, in order to reduce the impact on the transmission of the paper 11, in this embodiment, the first baffle 2 is correspondingly set at an angle, and since the printing press 1 is usually located at a higher height position at the inlet 13, the upper end of the first baffle 2 is close to the inlet 13 of the printing press 1, and the lower end of the first baffle 2 is close to the outlet 12 of the printing press 1.

[0036] Reference Figure 2 , Figure 3 Furthermore, in order to reduce the possibility of ink dots sliding away along the lower end of the first single plate, in this embodiment, a blocking portion 4 for blocking the ink dots is provided at the lower end of the first baffle 2, and the blocking portion 4 can be a blocking plate arranged perpendicular to the upper surface of the first plate body 21.

[0037] Among them, the first baffle 2 specifically includes two first plate bodies 21 that slide against each other, and a relatively sliding limiter 5 is arranged between the two first plate bodies 21. The ends of the two first plate bodies 21 away from the printing machine 1 are overlapped. Specifically, the first plate body 21 close to the outlet 12 of the printing machine 1 abuts against the upper surface of the first plate body 21 close to the inlet 13 of the printing machine 1. The upper surface of the first plate body 21 arranged close to the outlet 12 is penetrated by a first slide groove 211 along its own width direction. A plurality of first slide grooves 211 are arranged at intervals along the length direction of the first plate body 21. In this embodiment, there are specifically two of them, wherein the limiter 5 is a limit bolt threadedly connected to the first plate body 21 located below, the limit bolt is penetrated through the first slide groove 211, and the bolt portion of the limit bolt abuts against the upper surface of the first plate body 21 located on both sides of the first slide groove 211.

[0038] Furthermore, in order to reduce the possibility of ink dots passing through the first slide groove 211, in this embodiment, the first plate 21 is provided with an elastic strip 212 embedded in the first slide groove 211 to block the first slide groove 211 located above the paper 11, thereby reducing the possibility of ink dots passing through the first slide groove 211 to the paper 11 below.

[0039] Among them, the two fixing components 3 are respectively arranged at the two ends of the first plate body 21 away from each other. In this embodiment, the fixing component 3 specifically includes a fixing seat 31 fixedly connected to the opposite side walls of the printing machine 1 at the outlet 12 and the inlet 13, and a fixing bolt 32 threadedly connected to the fixing seat 31. In order to reduce damage to the printing machine 1 produced in the prior art, the fixing seat 31 can be bonded to the inner wall of the printing machine 1 by adhesive.

[0040] The implementation principle of a shielding structure for preventing printing paper from being contaminated in the embodiment of the present application is as follows: a first baffle 2 is provided between two adjacent printing machines 1 and is provided above the paper 11. Since the size of the first baffle 2 is larger than the size of the paper 11 exposed to the printing machine 1, the paper 11 is shielded to block the ink dots originally thrown onto the paper 11, so as to reduce the possibility of ink dots splashing on the paper 11, so as to prevent the possibility of printing paper 11 being contaminated. And since the two first plates 21 slide against each other, the size of the first baffle 2 can be adjusted according to the distance between the two printing machines 1 to improve the protection effect on the paper 11.

[0041] Embodiment 2:

[0042] Reference Figure 4 , which is different from the embodiment 1, is that a through groove 213 is provided along its thickness direction on the first plate 21 near the inlet 13 of the printing machine 1, so that the paper 11 can pass through. In order to reduce the possibility of ink spots being thrown on the paper 11 exposed to the first baffle 2, in this embodiment, a second baffle 6 is provided upwardly on the first plate 21. The second baffle 6 specifically includes a blocking portion 61 installed with the first plate 21 and a mounting portion 62 provided on the blocking portion 61 and installed with the printing machine 1. The second baffle 6 specifically includes a second plate rotatably connected with the first baffle 2 and a third plate rotatably connected with the second plate, wherein the second plate is the blocking portion 61 and the third plate is the mounting portion 62. In this embodiment, the second plate and the third plate each include two sliding plates arranged to slide relative to each other, and are specifically provided with a first sliding groove 211 and a stopper 5 to limit the relative sliding of the two sliding plates, which are arranged with the two first plate 21 in the first baffle 2, and will not be described in detail here. The adjacent sliding plates in the second plate and the third plate are rotatably connected. A fixing assembly 3 is also provided on the sliding plate in the third plate body close to the printing machine 1 for installation with the printing machine 1 .

[0043] Furthermore, in order to reduce the possibility that the ink dots thrown onto the first baffle 2 fall onto the paper 11 and the ink dots thrown onto the second baffle 6 rebound and fall onto the paper 11, in this embodiment, the upper surface of the first baffle 2 and the outer surface of the second baffle 6 away from the paper 11 are both provided with an absorbent member 7 for absorbing the ink dots. Specifically, the absorbent member 7 is elastic absorbent cotton or absorbent paper, which is adhered to the upper surface of the first baffle 2 by non-stick adhesive to absorb the swung ink dots.

[0044] Embodiment 3:

[0045] Reference Figure 5 , which is different from the embodiment 2 in that the lower end of the second baffle plate 6 is slidably connected to the first plate body 21, and the first plate body 21 is provided with a limiter 5 for limiting the sliding of the second baffle plate 6. Specifically, the sliding plate located at the bottom of the second plate body is fixedly connected with the slider 8, and the first plate body 21 is provided with a second slide groove 214 for the slider 8 to be slidably connected, and the limit bolt is passed through the slider 8 and is threadedly connected to the bottom inner wall of the second slide groove 214 to limit the sliding of the second plate body.

[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
