Description

Technical Field

[0001] The utility model relates to the technical field of printing plate cylinders, in particular to a high-definition wood grain imitation printing plate cylinder. Background Art

[0002] The plate cylinder is also called a steel roller. Plate cylinders are usually divided into hollow rollers, solid rollers, shafted rollers and non-shafted rollers. Plate cylinders are generally used for plate making and printing. Copper is plated on the surface of the drum, and then patterns are engraved by an intaglio electronic engraving machine, and then a layer of chromium is plated. Finally, products are batch-printed through the pattern engraved on the surface of the plate cylinder drum.

[0003] During the use of the plate cylinder, since different patterns often need to be printed, it is often necessary to replace and install plate cylinders with different patterns for printing. Due to the excessive self-weight of the solid plate cylinder, it is inconvenient to replace and install, resulting in a cumbersome actual printing operation process, consuming a large amount of working time and labor costs, and not being conducive to cost savings; although the hollow plate cylinder has a lighter self-weight, when different patterns need to be printed, the plate cylinder still needs to be disassembled and replaced, resulting in a cumbersome operation, a long time-consuming process, and a large demand for plate cylinders with different patterns, resulting in a high production cost. In order to reduce the disassembly difficulty of the plate cylinder and reduce the printing cost of the plate cylinder, the utility model proposes a high-definition wood grain imitation printing plate cylinder. Content of the Utility Model

[0004] The utility model aims to solve at least one of the technical problems in the related technologies to some extent. For this reason, an object of the utility model is to provide a high-definition wood grain imitation printing plate cylinder with a roll surface formed by combining multiple roll surface components, which can be disassembled and separated, has a light self-weight, a firm and stable structure, and is convenient for disassembly, washing and maintenance.

[0005] The technical solution is as follows:

[0006] A high-definition wood grain imitation printing plate cylinder includes a plate cylinder main body. The plate cylinder main body is a hollow shafted plate cylinder. The plate cylinder main body includes a core shaft. A roll surface is detachably connected to the periphery of the core shaft. The roll surface is radially and evenly disassembled into four sheet-shaped roll surface components. The core shaft includes a core shaft main body. Support plates a and b are respectively fixed at both ends of the core shaft main body. A connecting rod structure is arranged between the support plates a and b corresponding to the roll surface components. One end of the connecting rod structure is fixedly connected to one side of the end face of the support plate a, and the other end side is fixedly connected to the periphery of the support plate b. A chute is arranged at the connecting side of two adjacent roll surface components corresponding to the connecting rod structure. Both ends of the chute are open. A fixing plate is detachably connected to one side of the support plate b.

[0007] Furthermore, the diameter of the support plate a is larger than the diameter of the support plate b, the outer side diameter of the roller surface matches the diameter of the support plate a, the inner side wall diameter of the roller surface matches the diameter of the support plate b, and the fixed plate diameter matches the diameter of the support plate a.

[0008] Furthermore, the connecting rod structure includes a connecting rod main body, which is a rod with an "I"-shaped cross-section. An extension rod is vertically provided on one side of the connecting rod main body connected to the support plate b. One end of the extension rod is fixedly connected to the connecting rod main body, and the other end is fixedly connected to the peripheral side of the support plate b. The slide groove formed by fitting the slide grooves on one side of the two adjacent roller surface assemblies matches the size of the connecting rod structure.

[0009] Furthermore, both ends of the chute are open.

[0010] Furthermore, one end of the connecting rod structure connected to the support plate b is horizontally aligned with the end surface of the support plate b, and the length of the roller surface assembly matches the length of the connecting rod structure.

[0011] Furthermore, the support plate a and the support plate b are both provided with a roller on the side away from the core shaft, and a screw plate is fixed on the side of the support plate b where the roller is provided. The screw plate is provided with threads on the circumference, and matching screw holes are provided on the fixed plate corresponding to the screw plate. Two handles are symmetrically provided on one side of the fixed plate, and the handles are L-shaped.

[0012] Furthermore, a through opening with matching size is provided on one side of the fixed plate corresponding to the roller shaft.

[0013] Beneficial effects of the utility model:

[0014] 1. The setting of the hollow plate roller of the utility model can effectively reduce the dead weight of the plate roller, thereby reducing the difficulty of disassembling and assembling the plate roller.

[0015] 2. By disassembling the roller surface of the plate roller into four sheet-shaped roller surface components, the roller surface components on the plate roller surface can be quickly replaced separately when the printing pattern of the plate roller needs to be replaced. This not only avoids the complicated operation of disassembling and assembling when replacing the plate roller, effectively reducing the printing cost of the plate roller, but also facilitates the daily disassembly, cleaning and maintenance of the plate roller surface components.

[0016] 3. The roller surface assembly is assembled and fixed by arranging a connecting rod structure on the circumferential side of the core shaft, and the assembled roller surface assembly is further reinforced and fixed by screwing a fixing plate on one side of the plate roller, which effectively improves the firmness of the plate roller structure in the utility model and the stability of the roller surface assembly during printing.

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0025] Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present utility model and should not be construed as a limitation to the present utility model.

[0026] Please refer to Figures 1 to 5 as shown, a high-definition wood grain printing plate roll includes a plate roll body. The plate roll body is a hollow plate roll with a roll shaft. The plate roll body includes a mandrel 1, and a roll surface is detachably connected to the circumferential side of the mandrel 1. The roll surface is radially and evenly disassembled into four sheet-like roll surface assemblies 2.

[0027] As Figure 2As shown, the mandrel 1 includes a mandrel body, and a support plate a 103 and a support plate b 105 are respectively fixed at both ends of the mandrel body. The diameter of the support plate a 103 is larger than that of the support plate b 105. Corresponding to the roller surface assembly 2, a connecting rod structure 102 is provided between the support plate a 103 and the support plate b 105. The connecting rod structure 102 includes a connecting rod body, the connecting rod body is rod-shaped with a cross-section in the shape of "I", an extension rod is vertically provided on one side of the connecting rod body, one end of the extension rod is fixedly connected to the connecting rod body, and the other side of the end where the extension rod is located is fixedly connected to the circumferential side of the support plate b105.

[0028] As Figures 3 to 5 , the outer side diameter of the roller surface matches the diameter of the support plate a 103, and the inner side wall diameter of the roller surface matches the diameter of the support plate b 105. Corresponding to the connecting rod structure 102, a chute 201 is provided at the connecting side surface of two adjacent roller surface assemblies 2. Both ends of the chute 201 are open, and the chute 201 formed after the chutes 201 on one side of two adjacent roller surface assemblies 2 are fitted matches the size of the connecting rod structure 102.

[0029] According to the above solution, in the present utility model, by connecting and installing the connecting rod structure 102 between the support plates a 103 and b 105 on both sides, not only can the roller surface assembly 2 be assembled and fixed through the connecting rod structure 102, but also the structure of the mandrel 1 can be further strengthened, making the structure of the mandrel 1 more firm and stable.

[0030] One connecting rod structure 102 can simultaneously embed and fix one side edge of two roller surface assemblies 2. One roller surface assembly 2 needs to be reinforced and connected on both its sides by two connecting rod structures 102. The connection method between the connecting rod structure 102 and the roller surface assembly 2 makes the stability and firmness of the roller surface assembly 2 assembled and connected to the circumferential side of the mandrel 1 better.

[0031] The arrangement of the hollow plate roller makes the self-weight of the printing plate roller in the present utility model lighter and easier to be replaced and installed; and the roller surface disassembled into four sheet-like components not only effectively reduces the difficulty of daily maintenance and cleaning of the roller surface, reduces the difficulty of replacing the printing pattern of the plate roller, but also effectively reduces the production cost of printing different patterns on the plate roller.

[0032] As Figure 4 shown, the end of the connecting rod structure 102 connected to the support plate b 105 is connected to the support plate b

[0033] The 105 end faces are horizontally aligned, the length dimension of the roller surface assembly 2 matches the length dimension of the connecting rod structure 102, roller shafts 101 are provided on both sides of the support plate a 103 and the support plate b 105 away from the core shaft 1, and a fixing plate 3 is detachably screwed and connected to the side of the support plate b 105 where the roller shaft 101 is provided. A screwing plate 104 is fixed on one side of the support plate b 105 corresponding to the fixing plate 3. Threads are provided on the periphery of the screwing plate 104, and matching screw holes are provided on the fixing plate 3 corresponding to the screwing plate 104. Two handles 301 are symmetrically provided on one side of the fixing plate 3, and the handles 301 are L-shaped.

[0034] The diameter dimension of the fixing plate 3 matches the diameter dimension of the support plate a 103, and a through hole 302 with a matching dimension is provided on one side of the fixing plate 3 corresponding to the roller shaft 101.

[0035] According to the above solution, both ends of the roller surface assembly 2 are limited and fixed by the support plate a 103 and the fixing plate 3 respectively.

[0036] When replacing the roller surface on the periphery of the core shaft 1, as long as the four sheet-shaped roller surface assemblies 2 in a group are corresponding to the ends of the connecting rod structures 102 on one side of the support plate b 105, and the two connecting rod structures 102 are embedded into the sliding grooves 201 on both sides of the roller surface assembly 2 to slidably connect the roller surface assembly 2 to the periphery of the core shaft 1 until one end of the roller surface assembly 2 is pushed against one side of the support plate a 103, the assembly and replacement of the roller surface can be easily completed. Finally, the fixing plate 3 is screwed and fixed on one side of the support plate b 105, and the other end of the roller surface assembly 2 is limited and fixed by the fixing plate 3, so as to firmly assemble and connect the roller surface assembly 2 between the support plate a 103 and the fixing plate 3.

[0037] Among them, the through hole 302 provided on one side of the fixing plate 3 corresponding to the roller shaft 101 can quickly pass through the roller shaft 101 through the through hole 302 when screwing the fixing plate 3 to correspondingly connect it with the screwing plate 104, instead of having to first set it on the roller shaft 101 and then correspondingly connect it with the screwing plate 104, effectively improving the working efficiency of connecting the fixing plate 3 and making the operation process of fixing the roller assembly 2 simpler.

[0038] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent replacements or changes, and should be covered within the protection scope of the present invention.
