Description

Technical Field

[0001] This invention relates to the field of printing technology, specifically to a multi-nozzle color inkjet printing paper receiving device. Background Technology

[0002] Inkjet printing is a new plateless printing method. Through a special device and under computer control, piezoelectric crystals in the nozzles generate pulses that expel ink and spray it as a mist of ink droplets onto a substrate such as paper. Based on the electrostatic effect, the ink droplets directly form an image on the printed surface. An inkjet printer consists of a system controller, an inkjet controller, printheads, and a paper drive mechanism. Under the control of the inkjet controller, ink is ejected from the nozzles of the printheads and printed onto the paper. The paper drive mechanism feeds the paper as required, and the system controller is responsible for overall coordination.

[0003] After inkjet printing is completed, a paper collection device is needed to collect the printed paper. Generally, the paper is stacked in the paper collection device under the action of inertia to achieve paper collection. When printing test papers, because the test paper is large and thin, it is very easy for the paper to wrinkle and fold when it falls under the action of inertia after printing, which affects the collection and storage of test papers. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a multi-nozzle color inkjet printing paper collection device, which can solve the problem that when printing test papers, due to the large and thin paper size, the paper is prone to wrinkling and folding when falling under inertia after printing, which affects the collection and storage of test papers.

[0005] To achieve the above objectives, the technical solution of the present invention is as follows:

[0006] This invention is achieved through the following technical solution: a multi-head color inkjet printing paper receiving device.

[0007] The device includes a printing press. The printing press has a paper receiving component at its discharge port and a second support component fixed to its side. Inside the receiving component is a first support component, which, along with the second support component, is used to collect the printed paper into the receiving component. The first support component is connected to an inclined moving component, which moves the first support component. A rotary drive component is located on the side of the receiving component, which drives the first support component to rotate. The second support component is rotatably connected to the printing press's discharge port via a reset assembly. The second support component is connected to the moving component, and when the moving component moves, it drives both the first and second support components to rotate simultaneously. The synchronous rotation of the first and second support components is used for paper feeding and receiving in the printing press.

[0008] Furthermore, the first support includes a reset assembly, a baffle, a sleeve, a first support plate, and a rotating shaft. The rotating shaft is connected to the moving part through the reset assembly, and baffles are fixed at both ends of the rotating shaft. Multiple sleeves are fixed at equal intervals on the outer surface of the rotating shaft, and the first support plate is fixed on the side of each sleeve.

[0009] Furthermore, the storage component includes a side plate and a base, with the side plates fixed to both sides of the base; the movable component has two parts and is fixed to the two side plates respectively; the movable component includes a pneumatic guide rail and a pneumatic slider, the pneumatic guide rail is inclinedly fixed to the surface of the side plate, and the pneumatic guide rail is slidably connected to the pneumatic slider.

[0010] Furthermore, the rotary drive component includes a first screw and a fixing plate, the fixing plate being fixed to the end of the base, and the surface of the fixing plate being threadedly connected to the first screw; the first screw is adapted to the baffle.

[0011] Furthermore, the second support includes a second support plate, a pull rope, and a guide wheel. The second support plate is rotatably connected to the bottom end of the printing machine's outlet via a reset assembly, and the second support plate is connected to the pull rope. The pull rope passes through the guide wheel and is connected to the pneumatic slider, and the guide wheel is connected to the base.

[0012] Furthermore, it also includes a limiting member, which has two symmetrical sets and includes a limiting plate; the limiting plate adopts an inclined structure, and the opening width of the two limiting plates is greater than the bottom width of the limiting plate.

[0013] Furthermore, the limiting component also includes a second screw, a motor, and a cam; a placement groove is formed on the surface of the base; a spring is provided in the placement groove, and the limiting plate is slidably connected to the placement groove; the two limiting plates are connected by the spring; the side plate is threadedly connected to the second screw, and a motor is fixed to the end of the second screw; the motor is connected to the cam, and the cam is engaged with the limiting plate.

[0014] Furthermore, the limiting component also includes a binding strip, and storage slots are opened on opposite sides of the two limiting plates. The binding strip is placed in the storage slots and the placement slots. The binding strip adopts a frame structure. The binding strip is used to bind and lift the printed stacked paper.

[0015] Furthermore, it also includes a back stop, which includes a limiting groove, a locking bolt, and a back plate; the limiting groove is opened at the top of the base and is slidably connected to the back plate; multiple holes are opened on both sides of the limiting groove, and the back plate is connected to the holes by the locking bolt.

[0016] Compared with the prior art, the beneficial effects of the present invention include:

[0017] The printing paper receiving device of the present invention uses a first support member to receive the output paper. As the paper continues to be output, the first support member moves synchronously to support the paper. At the same time, the second support member supports the other end of the output paper, preventing the output paper from falling off due to gravity and inertia, thus avoiding folding or wrinkling of the output paper. This facilitates the collection of the printed paper and improves the printing quality.

[0018] After the paper is output, the limit plate moves repeatedly to straighten the stacked paper, ensuring that the printed paper is stacked more neatly for easy handling and collection. Attached Figure Description

[0026] It is readily understood that, based on the technical solution of this invention, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of the invention. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of this invention.

[0027] Multi-head color inkjet printing paper delivery device, such as Figure 1 As shown, the printer includes a printing press 1, which includes multiple ink cartridges 11. Each ink cartridge 11 has a multi-printer module 12 at its bottom and a discharge port 13 on its side.

[0028] The printing machine 1 has a paper storage component at the discharge port 13 end. The storage component includes a side plate 2 and a base 3. The side plates 2 are fixed on both sides of the base 3, and the printing machine 1 is fixed to the top side of the base 3.

[0029] A second support 7 is fixed to the side of the printing machine 1; the second support 7 is rotatably connected to the discharge port 13 of the printing machine 1 via a reset assembly.

[0030] The storage component has a first support 6 inside, and the first support 6 and the second support 7 are used to collect the printed paper into the storage component; the first support 6 is connected to an inclined moving part 9, and the moving part 9 is used to drive the first support 6 to move; the side of the storage component has a rotation drive 5, and the rotation drive 5 is used to drive the first support 6 to rotate; the second support 7 is connected to the moving part 9, and when the moving part 9 moves, it can drive the first support 6 to move and rotate while simultaneously driving the second support 7 to rotate; the first support 6 and the second support 7 rotate synchronously for feeding and collecting paper from the printing press 1.

[0031] For example, such as Figure 4 As shown, the first support member 6 includes a reset assembly 61, a baffle 62, a sleeve 63, a first support plate 631, and a rotating shaft 64. The rotating shaft 64 is connected to the moving member 9 through the reset assembly 61. The reset assembly 61 includes either a spring-loaded spring or a torsion spring, but is not limited to these. Two moving members 9 are provided and are respectively fixed on the two side plates 2. The moving member 9 includes a pneumatic guide rail 91 and a pneumatic slider 92. The pneumatic guide rail 91 is inclinedly fixed to the surface of the side plate 2, and the pneumatic guide rail 91 is slidably connected to the pneumatic slider 92. The moving member 9 can also be an electric linear guide rail. Any component capable of linear movement is within the protection scope of this invention.

[0032] The rotating shaft 64 is connected to the pneumatic slider 92 via the reset assembly 61. Baffles 62 are fixed at both ends of the rotating shaft 64. Multiple sleeves 63 are fixed at equal intervals on the outer surface of the rotating shaft 64, and a first support plate 631 is fixed on the side of each sleeve 63. The first support plate 631 is used to support the printed paper.

[0033] The rotary drive component 5 includes a first screw 51 and a fixing plate 52. The fixing plate 52 is fixed to the end of the base 3, and the first screw 51 is threadedly connected to the surface of the fixing plate 52. The first screw 51 is adapted to the baffle 62. Rotating the first screw 51 can adjust the length of the first screw 51 extending out of the fixing plate 52. During the downward movement of the first support plate 631, the baffle 62 contacts the first screw 51. As the baffle 62 continues to move downward with the pneumatic slider 92, the first screw 51 blocks the baffle 62, causing the rotating shaft 64 to rotate, thereby causing the first support plate 631 to rotate and complete the paper falling.

[0034] The second support 7 includes a second support plate 71, a pull rope 72, and a guide wheel 73. Multiple second support 7s are provided; for example, two second support 7s are provided. The second support plate 71 is rotatably connected to the bottom end of the discharge port 13 of the printing machine 1 via a reset assembly. The reset assembly includes either a spring-loaded spring or a torsion spring, but is not limited to these. The second support plate 71 is connected to the pull rope 72. The pull rope 72 passes through the guide wheel 73 and is connected to the pneumatic slider 92. The guide wheel 73 is connected to the base 3. As the pneumatic slider 92 moves on the pneumatic guide rail 91, when the first support 6 moves to the lower right, it can drive the second support plate 71 to move via the pull rope 72. After the paper printing is completed, the first support plate 631 and the second support plate 71 support and move downwards, allowing the paper to enter the receiving component, completing the paper receiving action.

[0035] To ensure that the printed paper can be stacked neatly, the present invention also includes a limiting member 8, such as... Figure 2 As shown, the limiting member 8 has two symmetrical sets, and the limiting member 8 includes a limiting plate 84; the limiting plate 84 adopts an inclined structure, and the opening width of the two limiting plates 84 is greater than the bottom width of the limiting plate 84.

[0036] To further organize the printed paper and ensure neat stacking by tapping it back and forth with the limiting plate 84, the limiting component 8 also includes a second screw 81, a motor 82, and a cam 83; a placement groove 31 is formed on the surface of the base 3; a spring 32 is provided in the placement groove 31, and the limiting plate 84 is slidably connected to the placement groove 31; the two limiting plates 84 are connected by the spring 32; the side plate 2 is threadedly connected to the second screw 81, and the end of the second screw 81 is fixed with the motor 82; the motor 82 is connected to the cam 83, and the cam 83 is engaged with the limiting plate 84; when the motor 82 starts, it can drive the cam 83 to rotate; when the protruding end of the cam 83 contacts the limiting plate 84, it pushes the two limiting plates 84 closer to each other; when the cam 83 rotates away, the limiting plate 84 is reset under the action of the spring 32, and so on, to organize the printed paper;

[0037] To facilitate the extraction of the printed paper, the limiting member 8 also includes a binding strip 85, such as... Figure 3 As shown, storage slots 841 are opened on opposite sides of the two limiting plates 84. Binding strips 85 are placed in the storage slots 841 and the placement slots 31. The binding strips 85 adopt a frame structure. The binding strips 85 are used to bind and lift the printed stacked paper. During printing, the binding strips 85 are placed in the storage slots 841 and the placement slots 31. After the printing paper is finished, it is stacked on the base 3, which can be stacked in the binding strips 85. After the printed paper is stacked to a suitable height, all the printed paper can be lifted out through the binding strips 85.

[0038] To limit the position of the printed paper on the back, the present invention also includes a back stop 4, which includes a limiting groove 41, a locking bolt 42, and a back plate 43. The limiting groove 41 is opened at the top of the base 3 and the limiting groove 41 is slidably connected to the back plate 43. Multiple holes are opened on both sides of the limiting groove 41, and the back plate 43 is connected to the holes by the locking bolt 42. The position of the printed paper falling and stacking is determined, and then the back plate 43 is moved so that the back plate 43 moves within the limiting groove 41. After moving to a suitable distance, the locking bolt 42 is inserted into the corresponding hole to complete the fixation.

[0039] In use, the paper receiving device in its initial state is as follows: Figure 1As shown, after printing is successful by printing press 1, the printed paper is output from the discharge port 13. The right end of the paper enters the second pallet 71, which supports the paper. At the same time, the pneumatic slider 92 is activated, causing it to move on the pneumatic guide rail 91. This moves the first support 6 to the right along the pneumatic guide rail 91. While the pneumatic slider 92 moves on the pneumatic guide rail 91, the paper continues to be output from printing press 1. The first support 6 moves the paper to the lower right. As the first support 6 moves, the pneumatic slider 92 moves, causing the second pallet 71 to rotate. This causes both ends of the printed paper to be supported by the first pallet 631 and the second pallet 71 and move downwards. When the paper reaches the baffle 62 on the side of the first screw 51, the first screw 51 blocks the baffle 62 as the first support 6 continues to move to the right. Figure 5 As shown, the rotating shaft 64 rotates, and the first support plate 631 rotates synchronously when the rotating shaft 64 rotates. At this time, the first support plate 631 loses support for the paper under the pull of the pneumatic slider 92, and the printed paper falls off.

[0040] The falling paper enters the limiting member 8, and the right end of the paper is blocked by the back stop member 4. The paper falls from the opening of the limiting plate 84. The motor 82 is turned on, and when the motor 82 starts, it drives the cam 83 to rotate. When the cam 83 rotates, it repeatedly hits the limiting plate 84. The two limiting plates 84 move closer to each other under the hitting of the cam 83, which straightens the printed paper. After the cam 83 rotates away, the limiting plates 84 move away from each other under the action of the spring 32. In this way, the paper that has been printed and fallen is repeatedly straightened. After one sheet of paper is placed, the first support member 6 is reset to transport the next sheet of paper.

[0041] After the paper on the base 3 is stacked to a certain thickness, all the stacked paper can be removed by using the handle strapping strip 85, and a new strapping strip 85 can be placed in the placement slot 31 and storage slot 841 to collect the newly printed paper.

[0042] The printing paper receiving device of the present invention uses a first support member to receive the output paper. As the paper continues to be output, the first support member moves synchronously to support the paper. At the same time, the second support member supports the other end of the output paper, preventing the output paper from falling off due to gravity and inertia, thus avoiding folding or wrinkling of the output paper. This facilitates the collection of the printed paper and improves the printing quality.

[0043] After the paper is output, the limit plate moves repeatedly to straighten the stacked paper, ensuring that the printed paper is stacked more neatly for easy handling and collection.

[0044] The technical scope of this invention is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this invention, and all such modifications and variations should fall within the protection scope of this invention.
