This arrangement results in a large installation area of ​​the magnets on the circumference of the roller and a large number of installations, which increases costs. Utility Model Content

[0003] The present application aims to at least solve the technical problem in the related art that in order to adsorb the wound plate, the magnetic roller of a large-scale flexible platemaking machine needs to install magnetic parts on the entire circumference of the roller, resulting in a large installation area of ​​the magnetic parts on the circumference of the roller, a large number of installations, and increased costs.

[0004] To this end, the present application provides a plate making device.

[0005] In view of this, the present application provides a plate-making device, which is used for engraving plate materials, and the plate-making device includes: a frame; a carrying platform, which is arranged on the frame and is used to carry the plate materials; a roller assembly, which is arranged on the frame; a first driving assembly, which is connected to the roller assembly and is used to drive the roller assembly to rotate on the frame; the roller assembly includes a cylinder, a positioning member and a plurality of magnetic members, the plurality of magnetic members are arranged on the cylinder, the positioning member is arranged on the circumferential surface of the cylinder, and the positioning member extends from one end of the cylinder to the other end of the cylinder along the axial direction of the cylinder; wherein the plate material can be laid on the carrying platform, and one end of the plate material is clamped on the positioning member, so that as the roller assembly rotates, the plate material is adsorbed and wound on the cylinder by the magnetic member, and the positioning member is intercepted along the radial direction of the roller assembly, and the line between the positioning member and the axis of the roller assembly is L, and the axis of the roller assembly is taken as the center of the circle O, and the line L is deflected by a preset angle θ toward a side away from the positioning member, and the plurality of magnetic members are distributed on the circumferential surface area of ​​the cylinder outside the preset angle θ.

[0006] The plate-making device provided in the present application is used for engraving plate materials, and the plate-making device includes a frame, a bearing platform, a roller assembly, and a first driving assembly. Among them, a bearing platform is provided on the frame, and the bearing platform is used to bear the plate material, the roller assembly is installed on the frame, and the first driving assembly is connected to the roller assembly, so that the roller assembly can be driven to rotate on the frame under the drive of the first driving assembly. Through the rotation of the roller assembly, the plate material is adsorbed and wound, thereby completing the adsorption function of the special plate material, improving the accuracy of the laser engraved plate material, and reducing the error.

[0007] Specifically, the roller assembly includes a cylinder, a positioning member and a plurality of magnetic members. Among them, there are a plurality of magnetic members, and the plurality of magnetic members are arranged on the cylinder to realize that the cylinder is a magnetic cylinder, and the cylinder can adsorb and wrap the plate material during rotation. The positioning member is arranged on the circumference of the cylinder, and along the axis direction of the cylinder, the positioning member extends from one end of the cylinder to the other end of the cylinder, that is, the setting direction of the positioning member is parallel to the axis of the cylinder, and the positioning member is arranged horizontally on the circumference of the cylinder.

[0008] Specifically, the positioning member plays a role in fixing and positioning the plate in the plate-making device. By fixing one end of the plate on the cylinder, when the cylinder rotates, the plate can be adsorbed and attached to the cylinder as the cylinder rotates, so as to achieve adsorption and winding of the plate, thereby completing the adsorption function of the special plate, improving the accuracy of the laser engraved plate, and reducing errors. It can be understood that the bearing platform is a platform for placing the plate, that is, the plate can be laid on the bearing platform, and one end of the plate is clamped on the positioning member. In this way, as the drum assembly rotates, the plate will be adsorbed and wound on the cylinder through the magnetic member, thereby completing the engraving of the plate, completing the adsorption function of the special plate, improving the accuracy of the laser engraved plate, and reducing errors.

[0009] Among them, the positioning member is intercepted along the radial direction of the roller assembly, the connecting line between the positioning member and the axis of the roller assembly is L, and the axis of the roller assembly is taken as the center of the circle O, and the connecting line L is deflected by a preset angle θ toward the side away from the positioning member; specifically, the preset angle θ satisfies: 0°<θ≤7.5°; in this way, a fan-shaped area is formed near the clamping and fixing area of ​​the positioning member, and when multiple magnetic members are arranged on the circumferential surface of the cylinder, it is only necessary to install the circumferential area distributed on the circumferential surface of the cylinder outside the preset angle θ, and there is no need to arrange the magnetic members on the circumferential area within the preset angle θ on the circumferential surface of the cylinder. It can be understood that, outside a fan-shaped area formed near the clamping and fixing area of ​​the positioning member, multiple magnetic members are arranged, and there is no need to install the magnetic members within the fan-shaped area, so as to reduce the number of magnetic members installed or reduce the proportion of magnetic members distributed on the cylinder.

[0010] By setting the magnetic parts outside the preset range of the clamping and fixing area of ​​the positioning parts, the magnetic parts are installed outside the preset range, that is, on the circumference area outside the preset angle θ on the circumference of the cylinder. Through this setting method, the number of magnetic parts set in the circumference area within the preset angle θ on the circumference of the cylinder is reduced, thereby reducing the number of magnetic parts installed and reducing production costs. In the related art, the magnetic roller of the large-scale platemaking machine for flexible plates needs to install magnetic parts on the entire circumference of the roller in order to adsorb the wound plate, which results in a large installation area of ​​the magnetic parts on the circumference of the roller, a large number of installations, and an increase in costs.

DETAILED DESCRIPTION

[0040] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0041] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present application is not limited to the specific embodiments disclosed below.

[0042] Refer to the following Figures 1 to 5 To describe the platemaking device 100 provided according to some embodiments of the present application.

[0043] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, an embodiment of the present application provides a plate-making device 100, which is used for engraving plate materials, and the plate-making device 100 includes: a frame 110; a carrying platform 150, which is arranged on the frame 110 and is used to carry the plate material; a roller assembly 130, which is arranged on the frame 110; a first driving assembly 140, which is connected to the roller assembly 130 and is used to drive the roller assembly 130 to rotate on the frame 110; the roller assembly 130 includes a cylinder 132, a positioning member 136 and a plurality of magnetic members 138, and the plurality of magnetic members 138 are arranged on the cylinder 132; the positioning member 136 is arranged on the circumferential surface of the cylinder 132, along the axial direction of the cylinder 132, as shown in FIG. Figure 4As shown, N is indicated as the axial direction of the cylinder 132. It can also be understood that N can also be the length direction of the cylinder 132. The positioning member 136 extends from one end of the cylinder 132 to the other end of the cylinder 132; wherein, the plate material can be laid on the supporting platform 150, and one end of the plate material is clamped on the positioning member 136, so that as the roller assembly 130 rotates, the plate material is adsorbed and wound on the cylinder 132 by the magnetic member 138, and the positioning member 136 is intercepted along the radial direction of the roller assembly 130. The line between the positioning member 136 and the axis of the roller assembly 130 is L, and with the axis of the roller assembly 130 as the center of the circle O, the line L is deflected by a preset angle θ toward the side away from the positioning member 136; multiple magnetic members 138 are distributed on the circumferential surface area of ​​the cylinder 132 outside the preset angle θ.

[0044] Specifically, Figure 2 and Figure 4 As shown, the plate-making device 100 includes a frame 110, a carrying platform 150, a roller assembly 130 and a first driving assembly 140. The frame 110 is provided with a carrying platform 150, which is used to carry the plate material, the roller assembly 130 is installed on the frame 110, and the first driving assembly 140 is connected to the roller assembly 130, so that the roller assembly 130 can be driven to rotate on the frame 110 under the drive of the first driving assembly 140. The plate material is adsorbed and wound by the rotation of the roller assembly 130, thereby completing the adsorption function of the special plate material, improving the accuracy of the laser engraving plate material, and reducing the error.

[0045] Specifically, Figure 2 As shown, the roller assembly 130 includes a cylinder 132, a positioning member 136 and a plurality of magnetic members 138. There are a plurality of magnetic members 138, and the plurality of magnetic members 138 are arranged on the cylinder 132, so that the cylinder 132 is a magnetic cylinder, and the cylinder 132 can adsorb and wrap the plate material during the rotation process. The positioning member 136 is arranged on the circumference of the cylinder 132, and along the axis direction of the cylinder 132, the positioning member 136 extends from one end of the cylinder 132 to the other end of the cylinder 132, that is, the setting direction of the positioning member 136 is parallel to the axis of the cylinder 132, and the positioning member 136 is arranged horizontally on the circumference of the cylinder 132.

[0046] Specifically, the positioning member 136 plays a role in fixing and positioning the plate in the plate-making device 100. By fixing one end of the plate on the cylinder 132, when the cylinder 132 rotates, the plate can be adsorbed and attached to the cylinder 132 as the cylinder 132 rotates, so as to achieve adsorption and winding of the plate, thereby completing the adsorption function of the special plate, improving the accuracy of the laser engraved plate, and reducing the error. It can be understood that the bearing platform 150 is a platform for placing the plate, that is, the plate can be laid on the bearing platform 150, and one end of the plate is clamped on the positioning member 136. In this way, as the roller assembly 130 rotates, the plate will be adsorbed and wound on the cylinder 132 by the magnetic member 138, thereby completing the engraving of the plate, completing the adsorption function of the special plate, improving the accuracy of the laser engraved plate, and reducing the error.

[0047] More specifically, the plate material currently in use is a steel base plate, which is heavy. The original air groove of the roller assembly 130 cannot adsorb the plate material on the surface of the cylinder 132. By installing a magnetic part 138 on the cylinder 132, the magnetic part 138 can firmly adsorb the plate material on the steel base plate, so that the flexible plate material on the steel base plate is snugly wrapped on the surface of the roller, and the cylinder 132 can adsorb and wrap the plate material during rotation.

[0048] Among them, Figure 5 As shown, the positioning member 136 is cut along the radial direction of the roller assembly 130, Figure 5 P in the figure indicates the radial direction of the roller assembly 130, the line between the positioning member 136 and the axis of the roller assembly 130 is L, and the axis of the roller assembly 130 is taken as the center of the circle O, and the line L is deflected by a preset angle θ toward the side away from the positioning member 136; specifically, the preset angle θ satisfies: 0°<θ≤7.5°; in this way, when the plurality of magnetic members 138 are arranged on the circumferential surface of the cylinder body 132, as Figure 5 As shown in the middle dotted area M, it is sufficient to install the magnetic parts 138 distributed on the circumferential area outside the preset angle θ on the circumferential surface of the cylinder 132, and there is no need to set the magnetic parts 138 on the circumferential area within the preset angle θ on the circumferential surface of the cylinder 132, so as to reduce the number of magnetic parts 138 installed or reduce the proportion of magnetic parts 138 distributed on the cylinder 132.

[0049] Specifically, since the positioning member 136 has a function of fixing and positioning the end of the plate material, the end of the plate material can be fitted and fixed on the cylinder 132, so that the plate material in the area around the positioning member 136 can be stably wound on the cylinder 132, and therefore, there is no need to set a magnetic member 138 on the circumferential surface of the cylinder 132 in the area around the positioning member 136 to absorb the plate material. Through calculation and experiment, it is found that in a cut-away view of the positioning member 136 taken along the radial direction of the drum assembly 130, when the center of the positioning member 136 is connected to the axis of the cylinder 132 and deflected to one side of the positioning member 136 within a range of 0° to 7.5°, there is no need to set a magnetic member 138. It can be understood that in the cut-away view of the positioning member 136 taken along the radial direction of the roller assembly 130, the axial line connecting the positioning member 136 and the cylinder 132 is centered, and the maximum deflection angle is 7.5° to one side. The circumference of the cylinder 132 within the range of this deflection angle does not need to be provided with magnetic members 138. This area includes the length direction and width direction areas of the circumference of the cylinder 132, because the circumference area within the preset angle θ on the circumference of the cylinder 132 can be clamped and fixed by the positioning member 136 to achieve adsorption and winding of the plate. This setting method can reduce the number of magnetic members 138, thereby achieving the purpose of reducing the number of magnetic members 138 installed and reducing production costs.

[0050] Alternatively, for a given platemaking device 100, the ratio of the area of ​​a region within a preset range near the clamping and fixing area of ​​the positioning member 136 to the area of ​​a region outside the preset range near the clamping and fixing area of ​​the positioning member 136 is set as a preset threshold, and the size of the preset threshold is calculated to determine the number of magnetic members 138 to be installed or the proportion of magnetic members 138 distributed in the cylinder, thereby reducing the number of magnetic members 138 to be installed or reducing the proportion of magnetic members 138 distributed in the cylinder 132.

[0051] like Figure 5 As shown, the magnetic member 138 is arranged outside the clamping and fixing area of ​​the positioning member 136, that is, on the peripheral area of ​​the cylinder 132 outside the preset angle θ, as shown in FIG. Figure 5 As shown in the dotted area M, a magnetic member 138 is installed. By this arrangement, the number of magnetic members 138 installed in the circumferential area within the preset angle θ on the circumferential surface of the cylinder 132 is reduced, thereby reducing the number of magnetic members 138 installed or reducing the proportion of magnetic members 138 distributed on the cylinder 132, thereby reducing production costs. In the related art, the magnetic roller of a large-scale platemaking machine for flexible plates needs to be installed with magnetic members on the entire circumferential surface of the roller in order to adsorb the wound plate, which results in a large installation area of ​​the magnetic members on the circumferential surface of the roller, a large number of installations, and an increase in costs.

[0052] In a specific application, the plate structure is that the base plate is a steel plate, a resin layer is attached to the steel plate, and a coating layer is arranged on the resin layer, that is, the plate structure is a plate synthesized by a three-layer structure, and since the magnetic member 138 can magnetically attract the steel plate, the magnetic cylinder 132 can absorb the plate and wind it on the cylinder 132. Before the plate making device 100 works, one end of the plate is clamped and fixed by the positioning member 136, and the positioning member 136 plays a role of fixing and positioning in this process, so that one end of the plate is fixed on the cylinder 132, so that when the cylinder 132 rotates, the plate can be adsorbed and attached to the cylinder 132 as the cylinder 132 rotates, so as to achieve adsorption and winding of the plate.

[0053] In a specific application, the positioning member 136 can be specifically set as a plate clamping assembly, which can be understood as a fixed clamping assembly to achieve clamping and fixing of the plate. It is precisely because the positioning member 136 has the function of clamping and fixing the plate that the magnetic member 138 is set outside the clamping and fixing area of ​​the positioning member 136, that is, on the peripheral area of ​​the cylinder 132 outside the preset angle θ, such as Figure 5 As shown in the dotted area M, the magnetic component 138 is installed. This arrangement can reduce the number of magnetic components 138 to be installed, thereby reducing the number of magnetic components 138 to be installed and reducing production costs.

[0054] In a specific application, the carrying platform 150 can be specifically configured as a carrying platform 150 of a stainless steel patterned plate.

[0055] In some embodiments, optionally, Figure 1 , Figure 2 and Figure 4 As shown, the platemaking device 100 also includes: a mounting platform 112, which is arranged on the frame 110, a bearing seat 120, which is arranged on the mounting platform 112, and a roller assembly 130 is arranged on the bearing seat 120; the roller assembly 130 also includes a rotating shaft 134, the rotating shaft 134 is passed through the cylinder 132, and the rotating shaft 134 is connected to the first driving assembly 140 to drive the cylinder 132 to rotate under the drive of the first driving assembly 140; wherein, the preset angle θ satisfies: 0°<θ≤7.5°.

[0056] Specifically, Figure 2As shown, the plate-making device 100 further includes a mounting platform 112 and a bearing seat 120. The mounting platform 112 is arranged on the frame 110; the bearing seat 120 and the first driving assembly 140 are arranged on the mounting platform 112, the roller assembly 130 is mounted on the bearing seat 120, and the first driving assembly 140 is connected to the roller assembly 130, so that the roller assembly 130 can be driven to rotate on the bearing seat 120 under the drive of the first driving assembly 140. The plate material is adsorbed and wound by the rotation of the roller assembly 130, thereby completing the adsorption function of the special plate material, improving the accuracy of the laser engraving plate material, and reducing the error.

[0057] Specifically, the preset angle θ satisfies: 0°<θ≤7.5°; in this way, a fan-shaped area is formed near the clamping and fixing area of ​​the positioning member 136, and when multiple magnetic members 138 are set on the circumference of the cylinder 132, it is only necessary to install them in the circumferential area outside the preset angle θ on the circumference of the cylinder 132, and there is no need to set the magnetic members 138 on the circumferential area within the preset angle θ on the circumference of the cylinder 132. In other words, in addition to forming a fan-shaped area near the clamping and fixing area of ​​the positioning member 136, multiple magnetic members 138 are set, and there is no need to install the magnetic members 138 within the fan-shaped area, so as to reduce the number of magnetic members 138 installed or reduce the proportion of magnetic members 138 distributed in the cylinder.

[0058] In a specific application, the mounting platform 112 can be specifically set as a marble platform, and the bearing seat 120 and the first driving assembly 140 are fixed on the marble platform by screws. The frame 110 can be specifically set as a cast steel frame 110, or a frame 110 made of other materials, which are not listed here.

[0059] In some embodiments, optionally, Figure 2 As shown, the platemaking device 100 also includes: a guide rail 160, which is disposed on the mounting platform 112 and arranged side by side with the cylinder 132; a light carving component 170, which is disposed on the guide rail 160 and can move along the guide rail 160.

[0060] Specifically, the plate-making device 100 further includes a guide rail 160 and a light engraving assembly 170. The guide rail 160 is mounted on the mounting platform 112, and the mounting direction of the guide rail 160 is arranged side by side with the cylinder 132, that is, the mounting direction of the guide rail 160 is arranged parallel to the axial direction of the cylinder 132. The light engraving assembly 170 is arranged on the guide rail 160, and the light engraving assembly 170 can move along the guide rail 160.
