Description

Technical Field

[0001] This invention relates to the field of printmaking technology, and more specifically to a printmaking machine. Background Technology

[0002] Contemporary printmaking refers to artworks conceived and created by artists and produced through plate-making and printing processes. Specifically, it involves carving or etching images onto a plate made of wood, stone, linoleum, copper, zinc, or other materials using knives or chemicals before printing. However, existing printmaking machines typically use rollers to apply color to the plate, but this design is only suitable for relief prints. Intaglio prints require that the ink be filled only into the grooves of the plate while ensuring that the outer surface of the plate remains untouched by ink, making existing printmaking machines unsuitable for intaglio printing.

[0003] Therefore, it is necessary to provide a new type of printing press. Summary of the Invention

[0004] In view of the above-mentioned problems existing in the prior art, the purpose of this invention is to provide a printing machine that can handle the coloring work of gravure printing.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A printing machine is provided, comprising a frame, a worktable, a spraying module, and a drive module. The spraying module is positioned above the worktable and includes a mounting block, a paint plate, a pull rope, a take-up reel, an elastic element, and a rotary driver. The mounting block is connected to the drive module, the paint plate is connected to the mounting block, the take-up reel is rotatably fitted onto the mounting block, and the rotary driver is connected to the take-up reel to drive its rotation. One end of the pull rope is connected to the paint plate, and the other end is connected to the take-up reel. The elastic element is positioned between the paint plate and the mounting block. The paint plate has a spraying surface and a pointed tip. The spraying surface faces the worktable, and paint is gathered on the spraying surface. The pointed tip is located at the end of the paint plate. When the take-up reel tightens the pull rope, the pull rope resists the elastic force of the elastic element, causing the paint plate to be in a first state, i.e., the pull rope pulls the paint plate to deform and bend until the pointed tip is higher than the spraying surface. When the take-up reel releases the pull rope, the elastic element applies elastic force, causing the paint plate to be in a second state, i.e., the elastic element pushes the paint plate to deform and bend until the pointed tip is lower than the spraying surface.

[0006] Furthermore, the coating panel includes a main body, a swing section, and a rotating structure. The main body is fixedly connected to the mounting block, the swing section is located at the end of the main body, and the sprayed surface and the tip are both located on the swing section. A rotating structure is provided between the main body and the swing section, which is connected to both the main body and the swing section, so that the swing section can swing relative to the main body around the rotating structure.

[0007] Furthermore, the coating plate also includes a deformation layer, which is connected to the main body and the swing section. The deformation layer is made of a flexible material, such that the deformation layer and the portion located between the main body and the swing section constitute a rotating structure.

[0008] Furthermore, the coating plate has spray holes on the side of the coating plate closer to the spraying surface, and an interface is provided on the side of the coating plate away from the spraying surface, and the interface is connected to the spray holes.

[0009] Furthermore, the spray holes are multiple, and a collecting cavity is provided on the coating plate between the interface and the multiple spray holes, the collecting cavity connecting the interface and the multiple spray holes.

[0010] Furthermore, the interface, nozzle, and collection cavity are located on the swing section.

[0011] Furthermore, the printing machine also includes an upper roller, which is rotatably mounted on the frame and located above the worktable.

[0012] Furthermore, the printing machine also includes a lower roller that rotates with the frame, the lower roller being located below the worktable, and the bottom wall of the worktable abutting against the peripheral side wall of the lower roller.

[0013] Furthermore, the frame is provided with a guide portion corresponding to the worktable for cooperating with the worktable to slide linearly on the frame.

[0014] Furthermore, the drive module includes a first linear module, a second linear module, and a third linear module. The first linear module, the second linear module, and the third linear module are drive devices that output linear motion power. The first linear module is used to drive the second linear module to perform linear reciprocating motion along a first direction, the second linear module is used to drive the third linear module to perform linear reciprocating motion along a second direction, and the drive end of the third linear module is connected to the mounting block of the paint spraying module through a connecting bracket.

[0015] The beneficial effects of this invention are as follows: This invention provides a printmaking machine, including a frame, a worktable, a paint spraying module, and a drive module. The worktable is slidably mounted on the frame along a straight line. The paint spraying module is positioned above the worktable and includes a mounting block, a paint plate, a pull rope, a take-up reel, an elastic element, and a rotary driver. The mounting block is connected to the drive module, enabling the drive module to drive the paint spraying module to move on the worktable. The paint plate is connected to the mounting block, and the take-up reel is rotatably engaged with the mounting block. The rotary driver is connected to the take-up reel, thereby driving the take-up reel to rotate. One end of the pull rope is connected to the paint plate. The other end is connected to a take-up reel. An elastic element is positioned between the paint plate and the mounting block. The paint plate has a spraying surface and a tip. The spraying surface faces the worktable, and paint is gathered on the spraying surface so that when the spraying surface approaches or contacts the template on the worktable, the paint adheres to the template. The tip is located at the end of the paint plate. When the take-up reel tightens the pull rope, the pull rope can resist the elastic force of the elastic element to keep the paint plate in the first state, that is, the pull rope pulls the paint plate to deform and bend until the tip is higher than the spraying surface. When the take-up reel loosens the pull rope, the elastic element can apply elastic force to keep the paint plate in the second state, that is, the elastic element pushes the paint plate to deform and bend until the upper tip is lower than the spraying surface. The controllable paint plate is initially in the first state. At this time, the drive module can drive the paint plate to move on the template, while the paint adheres to the template. For relief printing, it is only necessary to adjust the height of the spraying surface and the template so that the paint is applied to the outer surface of the template. For gravure printing, the height of the spraying surface and the template is adjusted so that the paint plate moves relative to the template until the paint at least completely covers the engraving grooves of the template. Then, the paint plate is controlled to be in the second state, and the paint plate is driven to move on the template again, while keeping the tip in contact with the outer surface of the template. Thus, the paint on the outer surface of the template is scraped off or moved into the engraving grooves by the tip of the paint plate, completing the coloring work of the gravure printing template.

[0029] Throughout this specification, reference to "an embodiment" or "an embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment is included in at least one embodiment of this application. Therefore, the phrases "in one embodiment," "in some embodiments," or "in some of these embodiments" appear in various places throughout the specification, and not all refer to the same embodiment. Furthermore, in one or more embodiments, a particular feature, structure, or characteristic may be combined in any suitable manner.

[0030] Please refer to Figures 1 to 7 As shown, a printmaking machine provided by the present invention will now be described. The printmaking machine includes a frame 1, a worktable 2, a paint spraying module 4, and a drive module 6. The worktable 2 is slidably mounted on the frame 1 along a straight line. The paint spraying module 4 is positioned above the worktable 2. The paint spraying module 4 includes a mounting block 41, a paint plate 42, a pull rope 43, a take-up reel 44, an elastic element 45, and a rotary driver 47. The mounting block 41 is connected to the drive module 6, enabling the drive module 6 to drive the paint spraying module 4 to move on the worktable 2. The paint plate 42 is connected to the mounting block 41. The take-up reel 44 is rotatably engaged with the mounting block 41. The rotary driver 47 is connected to the take-up reel 44, thereby driving the take-up reel 44 to rotate. The pull rope... One end of the pull rope 43 is connected to the paint plate 42, and the other end of the pull rope 43 is connected to the take-up reel 44. The elastic element 45 is disposed between the paint plate 42 and the mounting block 41. The paint plate 42 has a spraying surface 425 and a tip 426. The spraying surface 425 faces the worktable 2, and paint is gathered on the spraying surface 425 so that when the spraying surface 425 approaches or contacts the template 100 on the worktable 2, the paint adheres to the template 100. The tip 426 is located at the end of the paint plate 42. When the take-up reel 44 tightens the pull rope 43, the pull rope 43 can resist the elastic force of the elastic element 45 to keep the paint plate 42 in the first state, that is, the pull rope 43 pulls the paint plate 42 to deform and bend until the tip 426 is higher than the spraying surface 425; Figure 5As shown, when the take-up reel 44 releases the pull rope 43, the elastic element 45 can apply elastic force to put the paint plate 42 in the second state, that is, the elastic element 45 pushes the paint plate 42 to deform and bend until the upper tip 426 is lower than the painted surface 425. The controllable paint plate 42 is initially in the first state. At this time, the drive module 6 can drive the paint plate 42 to move on the template 100, while simultaneously adhering the paint to the template 100. For relief printing, it is only necessary to adjust the height between the spraying surface 425 and the template 100 so that the paint is applied to the outer surface of the template 100. For gravure printing, the height between the spraying surface 425 and the template 100 is adjusted so that the paint plate 42 moves relative to the template 100 until the paint at least completely covers the engraving groove of the template 100. Then, the paint plate 42 is controlled to be in the second state, and the paint plate 42 is driven to move on the template 100 again, while keeping the tip 426 against the outer surface of the template 100. Thus, the paint on the outer surface of the template 100 is scraped off or moved into the engraving groove through the tip 426 of the paint plate 42, completing the coloring work of the gravure printing template.

[0031] In some embodiments, to allow the paint plate 42 to be bent and deformed to adjust the relative position of the tip 426 and the sprayed surface 425, such as... Figure 3 As shown, the paint plate 42 includes a main body 421, a swing section 422, and a rotating structure 424. The main body 421 is fixedly connected to the mounting block 41. The swing section 422 is located at the end of the main body 421, and the sprayed surface 425 and the tip 426 are both located on the swing section 422. A rotating structure 424 is provided between the main body 421 and the swing section 422, which is connected to both the main body 421 and the swing section 422. This allows the swing section 422 to swing relative to the main body 421 around the rotating structure 424, causing the paint plate 42 to bend and deform. This causes the sprayed surface 425 and the tip 426 to swing around the rotating structure 424, thereby adjusting the tip 426 to be higher or lower than the sprayed surface 425.

[0032] Preferably, in some embodiments, the coating plate 42 further includes a deformation layer 423, which is connected to the main body 421 and the swing segment 422. The deformation layer 423 is made of a flexible material, such that the portion of the deformation layer 423 located between the main body 421 and the swing segment 422 constitutes a rotating structure 424. Due to the flexible deformability of the deformation layer 423, the swing segment 422 can swing and deform relative to the main body 421. It is understood that in other embodiments not shown, the rotating structure 424 may also be a hinged structure.

[0033] like Figure 4As shown, in some embodiments, a spray hole 427 is provided on the paint plate 42 on the side of the paint plate 42 near the spray surface 425, and an interface 428 is provided on the side of the paint plate 42 away from the spray surface 425. The interface 428 is used to connect a paint supply pipe (not shown) and is connected to the spray hole 427, so that the paint entering the interface 428 can overflow through the spray hole 427 and adhere to the spray surface 425. When the paint on the spray surface 425 contacts the template 100, the paint is transferred to the template 100. Specifically, there are multiple spray holes 427, and a collecting cavity 429 is provided on the paint plate 42 between the interface 428 and the multiple spray holes 427. The collecting cavity 429 connects the interface 428 and the multiple spray holes 427, so that the paint entering the interface 428 can flow into the collecting cavity 429 and move towards the multiple spray holes 427, thereby improving the paint supply from a single interface 428 to multiple spray holes 427. Specifically, the interface 428, the nozzle 427, and the collection cavity 429 are located on the swing section 422.

[0034] In some embodiments, the printing machine further includes an upper roller 3, which is rotatably fitted onto the frame 1 and is located above the worktable 2. After the paper is covered on the template, the worktable 2 is driven to translate so that the template and paper pass between the upper roller 3 and the worktable 2. The ink in the picture area on the template can be transferred to the paper by the squeezing between the upper roller 3 and the worktable 2, and the picture is printed on the paper.

[0035] like Figure 6 and Figure 7 As shown, in some embodiments, the printing machine also includes a lower roller 5 that rotates with the frame 1. The lower roller 5 is located below the worktable 2, and the bottom wall of the worktable 2 abuts against the peripheral wall of the lower roller 5. Thus, through the contact friction between the lower roller 5 and the worktable 2, rotating the lower roller 5 can drive the worktable 2 to slide along a straight line on the frame 1.

[0036] like Figure 7 As shown, in some embodiments, the frame 1 is provided with a guide portion 11 corresponding to the worktable 2 for linear sliding on the frame 1, and the worktable 2 is slidably engaged with the guide portion 11. Specifically, in this embodiment, the guide portion 11 is a slide rod installed on the frame 1 and located below the worktable 2. The slide rod is slidably engaged with the bottom wall of the worktable 2. Specifically, a guide wheel 12 is rotatably engaged on the slide rod. The guide wheel 12 contacts the bottom wall of the worktable 2, and the rolling friction between the guide wheel 12 and the worktable 2 reduces the frictional resistance between the guide portion 11 and the worktable 2.

[0037] like Figure 1 and Figure 2As shown, in some embodiments, the drive module 6 includes a first linear module 61, a second linear module 62, and a third linear module 63. The first linear module 61, the second linear module 62, and the third linear module 63 are drive devices that output linear motion power. The first linear module 61 is used to drive the second linear module 62 to perform linear reciprocating motion along a first direction. The second linear module 62 is used to drive the third linear module 63 to perform linear reciprocating motion along a second direction. The drive end of the third linear module 63 is connected to the mounting block 41 of the spraying module 4 through the connecting bracket 48 to drive the spraying module 4 to perform linear reciprocating motion along a third direction. The first direction, the second direction, and the third direction are perpendicular to each other, thereby driving the spraying module 4 to perform lifting and translating operations relative to the frame 1 and the worktable 2, so as to drive the spraying module 4 to apply color to the template 100 on the worktable 2.

[0038] In some embodiments, the first linear module 61, the second linear module 62, and the third linear module 63 are ball screw linear modules. In other embodiments not shown, the first linear module 61, the second linear module 62, and the third linear module 63 may also be synchronous belt linear modules or linear motors.

[0039] like Figure 6 and Figure 7 As shown, in some embodiments, the printing machine further includes an adjustment structure 7, which is used to adjust the height of the upper roller 3 on the frame 1, thereby adjusting the distance between the upper roller 3 and the worktable 2 so that the distance between the upper roller 3 and the worktable 2 can adapt to templates of different materials and thicknesses. Specifically, the adjustment structure 7 includes a slider 71 and a lead screw 72. The slider 71 is slidably engaged with the frame 1 in the vertical direction, and the end of the upper roller 3 is rotatably engaged with the slider 71. The lead screw 72 is rotatably engaged with the frame 1, and the lead screw 72 is threadedly engaged with the slider 71, so that when the lead screw 72 is rotated, it can drive the slider 71 to slide vertically on the frame 1, thereby driving the upper roller 3 to rise and fall on the frame 1, so that the distance between the upper roller 3 and the worktable 2 can be adjusted.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
