[0025] The following is a further detailed description of the technical solution of the present invention in conjunction with the accompanying drawings and specific embodiments. Figures 1 to 8 , the present application provides a printing sleeve roller which is easy to disassemble, please refer to Figure 1 and Figure 2 , including a main shaft 1, both sides of the main shaft 1 are connected with a disassembly assembly 4, the outer side of the main shaft 1 is movably provided with a sleeve assembly 2, the side of the disassembly assembly 4 away from the main shaft 1 is connected with a side rod assembly 3, the disassembly assembly 4 is operated to fix the sleeve assembly 2 to be in an installed state, the disassembly assembly 4 is reversely operated to separate from the sleeve assembly 2 to be in a disassembled state, and the sleeve assembly 2 can be quickly disassembled and assembled.

[0026] Please refer to Figure 2 , Figure 3 The sleeve assembly 2 includes a sleeve body 201, a mounting hole 202 is opened on one side of the sleeve body 201, the length of the mounting hole 202 is the same as the length of the sleeve body 201, fixing grooves 203 are opened on the circumference of both sides of the inner wall of the mounting hole 202, and the outer diameter of the main shaft 1 is clearance-matched with the inner diameter of the mounting hole 202.

[0027] Please refer to Figure 4 , Figure 7 The side rod assembly 3 includes a side rod body 301, a circular groove 303 is opened on the side of the side rod body 301 close to the main shaft 1, a first movable groove 304 is opened on the side of the circular groove 303 away from the main shaft 1, a first movable hole 302 is opened in the middle of the outer side of the side rod body 301, and a fixing hole 305 is opened on the side of the side rod body 301 away from the main shaft 1.

[0028] Please refer to Figure 4 The disassembly and assembly component 4 includes a driving wheel 401, a driving rod 402 is connected to the side of the driving wheel 401 close to the main shaft 1, a first limiting plate 403 is connected to the side of the driving rod 402 close to the main shaft 1, a second limiting plate 404 is rotatably provided on the side of the first limiting plate 403 close to the main shaft 1, and a disassembly and assembly rod 405 is slidably provided on the inner side of the second limiting plate 404. Rotating the driving wheel 401 drives the first limiting plate 403 to rotate relative to the second limiting plate 404, thereby driving the disassembly and assembly rod 405 to spread outward or gather toward the center.

[0029] Specifically, by setting the sleeve assembly 2 and the disassembly assembly 4 to cooperate with each other, when other content printing is required after a single batch of printing is completed, the sleeve assembly 2 with different content engraved on the outside needs to be replaced, and the disassembly assembly 4 is separated from the sleeve assembly 2 by removing the fixing assembly 5 and rotating the driving wheel 401, so that the sleeve assembly 2 can be quickly disassembled for replacement. During installation, it is only necessary to put the sleeve assembly 2 on the outside of the main shaft 1 and rotate the driving wheel 401 to quickly fix the disassembly assembly 4 and the sleeve assembly 2, which is convenient to operate and saves time and effort.

[0030] Please refer to Figure 5 , Figure 6 , Figure 7 The driving wheel 401 includes a rotating disk body 4011, and the side of the rotating disk body 4011 away from the main shaft 1 is rotatably connected to the side of the circular groove 303 close to the main shaft 1, and the side of the rotating disk body 4011 close to the main shaft 1 is fixedly connected to the driving rod 402, and a circular hole 4012 is opened on one side of the rotating disk body 4011, and a second movable groove 4013 is opened on the top and bottom of the rotating disk body 4011. A spring 4014 is fixedly connected to the inner wall of the second movable groove 4013 on the side close to the center of the rotating disk body 4011, and a rotating handle 4015 is fixedly connected to the end of the spring 4014 away from the center of the rotating disk body 4011.

[0031] Specifically, the outer diameter of the rotating handle 4015 at one end close to the center of the rotating disk body 4011 is clearance matched with the inner diameter of the second movable groove 4013, and the width of the outer side of the rotating handle 4015 is clearance matched with the width of the inner side of the first movable hole 302. The operator first squeezes the upper and lower rotating handles 4015 at the same time to make the rotating handles 4015 sink into the inner side of the first movable hole 302, so that the sleeve body 201 can pass through the driving wheel 401, and then slides the sleeve assembly 2 to the outside of the main shaft 1, so that the two ends of the sleeve body 201 are respectively aligned with the side of the first disk body 4031 close to the main shaft 1. When the rotating handle 4015 loses the squeezing force, it will extend out of the first movable hole 302 under the action of the spring 4014, so that the operator can rotate the rotating disk body 4011 by rotating the handle 4015.

[0032] Please refer to Figure 4 The first limiting plate 403 includes a first plate body 4031 , a side of the first plate body 4031 away from the main shaft 1 is fixedly connected to a side of the driving rod 402 close to the main shaft 1 , and arc holes 4033 are opened around one side of the first plate body 4031 .

[0033] Please refer to Figure 4 , Figure 5 The first limiting plate 403 includes a second plate body 4041, and the side of the second plate body 4041 away from the main shaft 1 is rotatably connected to the side of the first plate body 4031 close to the main shaft 1, and I-shaped holes 4042 are opened around one side of the second plate body 4041. The side of the second plate body 4041 close to the main shaft 1 is fixedly connected with a support rod, and the support rod of the second plate body 4041 is fixedly connected to the main shaft 1.

[0034] Specifically, the support rod of the second plate body 4041 can position the second limiting plate 404 to ensure that the second limiting plate 404 is in a fixed state, and the first limiting plate 403 can rotate relative to the second limiting plate 404. When the first limiting plate 403 rotates, the overlapping position of the arc hole 4033 and the I-shaped hole 4042 moves.

[0035] Please refer to Figure 4 The disassembly and assembly plug rod 405 includes a limit rod 4051, a side of the limit rod 4051 away from the main shaft 1 is fixedly connected to a limit ring 4052, a side of the limit rod 4051 close to the main shaft 1 is fixedly connected to a limit block 4054, and a side of the limit block 4054 away from the center of the second disk body 4041 is fixedly connected to a fixed plug rod 4053, an outer diameter and shape of the fixed plug rod 4053 are clearance-matched with an inner diameter and shape of the fixed groove 203, and a length of the limit rod 4051 is the sum of the lengths of the second disk body 4041 and the first disk body 4031.

[0036] Specifically, the limiting rod 4051 is limited by the arc hole 4033 and the I-shaped hole 4042. The movement of the overlapping position of the arc hole 4033 and the I-shaped hole 4042 toward the center of the second disk body 4041 will drive the limiting rod 4051 to move along the overlapping position of the two. When the overlapping position of the arc hole 4033 and the I-shaped hole 4042 is closest to the center of the second disk body 4041, it is in the disassembly state; when the overlapping position of the arc hole 4033 and the I-shaped hole 4042 is farthest from the center of the second disk body 4041, it is in the installation completion state.

[0037] Please refer to Figure 8 The fixing assembly 5 includes a main fixing rod 501, and the end of the main fixing rod 501 close to the main shaft 1 is fixedly connected to the secondary fixing rod 502. The end of the driving rod 402 away from the main shaft 1 is provided with a slot. The outer diameter of the secondary fixing rod 502 and the inner diameter of the slot of the driving rod 402 are clearance matched. The outer diameter of the main fixing rod 501, the inner diameter of the fixing hole 305, the inner diameter of the circular hole 4012, and the width of the inner side of the first movable groove 304 are all clearance matched.

[0038] Specifically, along Figure 4 The installation is completed when the first movable groove 304 is rotated clockwise as shown. Figure 4 The first movable groove 304 is rotated counterclockwise until the other end is in the disassembly state, and the positions of the two fixing holes 305 and the two circular holes 4012 are consistent with the first movable groove 304. Figure 4 One ends of the two first movable grooves 304 are on the same straight line, and the installation is completed only when the circular hole 4012, the fixed hole 305 and the first movable groove 304 are all overlapped. At this time, the fixing component 5 is inserted into the fixing hole 305. Since the driving rod 402 is fixedly connected to the side of the circular hole 4012 close to the main shaft 1, the secondary fixing rod 502 is directly inserted into the driving rod 402 slot to complete the limit of the installation completion state of the device to avoid its deviation, so that the fixing groove 203 and the fixing plug 4053 are fixed more stably.

[0039] Please refer to Figure 4The circumference of the first plate 4031 is provided with grooves at equal intervals, and the inner side of each groove of the first plate 4031 is fixedly connected with a reflective strip 4032 .

[0040] Specifically, during the process of disassembling and assembling the sleeve assembly 2, it is necessary to rotate the driving wheel 401 to drive the first limit plate 403 to rotate, and the first limit plate 403 is located on both sides of the outside of the sleeve assembly 2. The operator can directly observe during operation. When the first plate body 4031 rotates driven by the driving wheel 401, the reflective strip 4032 will also rotate accordingly. At this time, the reflective strip 4032 will receive the light in the operating workshop to form an emitted light, which can remind the operator that it is currently in the disassembly mode or the installation mode, thereby preventing the operator from operating incorrectly.

[0042] How it works When printing of other contents is required after a single batch of printing is completed, the sleeve assembly 2 with different contents engraved on the outside needs to be replaced. At this time, the power of the printing machine needs to be turned off, and then the sleeve assembly 2 is separated from the spindle 1, that is, the sleeve assembly 2 that has completed the printing work is disassembled to replace the new sleeve assembly 2 for a new batch of printing work: When disassembling, the fixing components 5 on both sides must be separated from the driving rods 402 on both sides, that is, the auxiliary fixing rods 502 are separated from the driving rod 402 slots. At this time, the driving wheel 401 can rotate relative to the side rod body 301, such as Figure 4 As shown, grasp the rotating handle 4015 and rotate the rotating disk body 4011 to drive the first limiting disk 403 to rotate along the Figure 4 4041, the arc hole 4033 and the I-shaped hole 4042 overlap position to move closer to the center of the second disk 4041, and the limiting rod 4051 is limited by the arc hole 4033 and the I-shaped hole 4042, driving the limiting rod 4051 to move along the arc hole 4033 and the I-shaped hole 4042 overlap position to move closer to the center of the second disk 4041. When the arc hole 4033 and the I-shaped hole 4042 overlap position is closest to the center of the second disk 4041, it is in the disassembly state, that is, the fixing rod 4051 is fixed to the center of the second disk 4041. 53 is out of the fixing groove 203 and the outer diameter of the three fixing rods 4053 is smaller than the outer diameter of the second plate body 4041. At this time, the sleeve assembly 2 is no longer limited by the disassembly assembly 4. The sleeve assembly 2 can slide to one side relative to the main shaft 1 and the side rod assembly 3. When passing through the driving wheel 401 on one side, the operator can squeeze the upper and lower rotating handles 4015 at the same time to make the rotating handles 4015 sink into the inner side of the first movable hole 302, ensuring that the sleeve assembly 2 passes through the driving wheel 401 smoothly, and then disassemble and replace the new sleeve assembly 2. When installing a new sleeve assembly 2, the operator first squeezes the upper and lower rotating handles 4015 at the same time so that the rotating handles 4015 are immersed in the inner side of the first movable hole 302, so that the sleeve body 201 passes through the driving wheel disc 401, and then slides the sleeve assembly 2 to the outer side of the main shaft 1, so that the two ends of the sleeve body 201 are respectively aligned with the side of the first disk body 4031 close to the main shaft 1. When the squeezing force is lost, the rotating handle 4015 will extend out of the first movable hole 302 under the action of the spring 4014, so that the operator can rotate the rotating disk body 4011 by rotating the handle 4015. Figure 4 As shown, grasp the rotating handle 4015 along Figure 4 The rotating disk body 4011 is rotated clockwise, the rotating handle 4015 is rotated clockwise along the first movable hole 302 and drives the driving rod 402 to rotate clockwise along the first movable groove 304, so that the driving rod 402 drives the first disk body 4031 to rotate clockwise, so that the overlapping position of the arc hole 4033 and the I-shaped hole 4042 moves away from the center of the second disk body 4041, and drives the limiting rod 4051 to move along the overlapping position of the arc hole 4033 and the I-shaped hole 4042 away from the center of the second disk body 4041. When the device is at the point farthest from the center of the second disk body 4041, the fixed rod 4053 is completely inserted into the fixed groove 203, and each circular hole 4012, the fixed hole 305 and the first movable groove 304 overlap one by one. At this time, the installation is completed, and then the fixing component 5 is inserted into the fixing hole 305. Since the driving rod 402 is fixedly connected to the side of the circular hole 4012 close to the main shaft 1, the secondary fixing rod 502 is directly inserted into the driving rod 402 slot, completing the limit of the installation completion state of the device to prevent it from deflecting, so that the fixing groove 203 and the fixed rod 4053 are fixed more stably; During the process of disassembling and assembling the sleeve assembly 2, it is necessary to rotate the driving wheel 401 to drive the first limit plate 403 to rotate, and the first limit plate 403 is located on both sides of the outside of the sleeve assembly 2. The operator can directly observe during operation. When the first plate body 4031 rotates driven by the driving wheel 401, the arc hole 4033 will also rotate accordingly. At this time, the reflective strip 4032 will receive the light in the operating workshop to form emitted light, which can remind the operator that it is currently in disassembly mode or installation mode to prevent the operator from misoperation.

[0043] An example of the present specific implementation mode is described above, but the present embodiment is not limited to the above-mentioned specific implementation mode, which is merely illustrative and not restrictive. A person skilled in the art may make many forms inspired by the present embodiment, all of which are protected by the present embodiment.
