[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] like Figure 1-Figure 7As shown, the utility model discloses a plate roller that is easy to assemble, which consists of a roller body 1, a left rotating shaft 2 and a right rotating shaft 3. The axial direction of the roller body 1 extends horizontally, the left rotating shaft 2 is located on the left side of the roller body 1, and the right rotating shaft 3 is located on the right side of the roller body 1. The left rotating shaft 2 and the right rotating shaft 3 are respectively rotatably installed on the printing press, and at this time, the roller body 1 is driven to rotate by rotating the left rotating shaft 2 and the right rotating shaft 3 so that the content engraved on the copper layer of the roller body 1 can be printed on paper (this is the prior art and is not described in detail here). The left rotating shaft 2 includes a left positioning section 21 and a left disc 22 protruding to the right, and the right rotating shaft 3 includes a right positioning section 31 and a right disc 32 protruding to the left. The left positioning section 21 and the right positioning section 31 are both hexagonal prisms and are respectively inserted on the left and right sides of the roller body 1. The left disc 22 and the right disc 32 are both against the roller body 1 and are connected to the roller body 1 by bolts, buckles, etc. Removable connection, 1. Since the left positioning section 21 on the left rotating shaft 2 and the right positioning section 31 on the right rotating shaft 3 are both arranged in a polygonal prism, when the left rotating shaft 2, the roller body 1 and the right rotating shaft 3 are assembled together, the left positioning section 21 and the right positioning section 31 located in the roller body 1 cannot rotate along the axial direction compared with the roller body 1, thereby providing convenience for fixing the left rotating shaft 2, the roller body 1 and the right rotating shaft 3 together; 2. Since the left disc 22 and the right disc 32 are both against the roller body 1 and are detachably connected to the roller body 1, when the left positioning section 21 and the right positioning section 31 are respectively inserted into the roller body 1, the left disc 22 and the right disc 32 will be against the roller body 1 to realize the positional relationship of the left rotating shaft 2, the right rotating shaft 3 and the roller body 1, and since the left disc 22 and the right disc 32 are detachably connected to the roller body 1, the left rotating shaft 2 and the right rotating shaft 3 can be stably installed on the roller body 1.

[0029] Among them, the roller body 1 is provided with a plurality of positioning plugs 11 made of rubber or other materials that are easy to deform at intervals along the circumference to the right, each positioning plug 11 includes a fixed section 111 and a limiting section 112, the length direction of each fixed section 111 extends left and right and is fixed to the roller body 1 by welding or other means, the length direction of each limiting section 112 is perpendicular to the length direction of the corresponding fixed section 111, each limiting section 112 is inserted with a right disk 32 and is against the right side end face of the right disk 32, because the positioning plug 11 includes the fixed section 111 extending left and right in the length direction and the limiting section 112 perpendicular to the fixed section 111 in the length direction, after the right positioning section 31 is inserted into the roller body 1, At this time, before each fixing segment 111 is inserted into the right disc 32, it is necessary to bend the limiting segment 112 downward so that each limiting segment 112 can pass through the right disc 32. At this time, after each fixing segment 111 is inserted into the right disc 32, the limiting segment 112 can return to its original state after losing the force, that is, it extends up and down and abuts against the right side end surface of the right disc 32, thereby achieving the fixation of the roller body 1 and the right disc 32; and when the right disc 32 needs to be removed from the roller body 1, at this time, a downward force is applied to each limiting segment 112 to be bent downward, and the right disc 32 is moved to the right at this time, so that each limiting segment 112 can move to the left in the right disc 32 and separate from the right disc 32, thereby achieving the separation of the right disc 32 from the roller body 1.

[0030] In addition, it also includes a heat dissipation column 4 and a cover plate 5. The heat dissipation column 4 is coaxially arranged with the roller body 1, and a mounting groove 12 for inserting the heat dissipation column 4 is arranged in the roller body 1. The heat dissipation column 4 includes a left mounting section 41, a connecting section 42 and a right mounting section 43. The right positioning section 31 is inserted with the right mounting section 43. A cooling pipe 421 is fixedly installed on the connecting section 42 by bonding or the like. The cooling pipe 421 is coaxially arranged with the connecting section 42 and the length direction extends left and right. The roller body 1 is located on the right side of the connecting section 42 and is integrally formed. The type is provided with a limit plate 13 that abuts against the connecting section 42, and the roller body 1 is provided with a loading slot 14 on the left side of the installation slot 12. The cover plate 5 is located in the loading slot 14 and is detachably connected to the roller body 1 by means of bolts, buckles, etc. 1. During the printing process, the plate roller (especially the chrome-plated plate roller in gravure printing) will generate heat due to friction with the ink and high-speed operation. If it is not effectively cooled, the heat accumulation will cause the plate roller to expand, affecting the printing accuracy, causing problems such as inaccurate pattern overprinting and poor dimensional stability. Thereby affecting the printing quality and aesthetics of the final product, and high temperature will accelerate the aging process of the plate roller material, especially for the chrome plating layer, high temperature may cause the plating layer to fall off, accelerate corrosion, and shorten the service life of the plate roller. Therefore, the cooling pipe 421 installed in the roller body 1 is filled with coolant, and the cooling pipe 421 is fixed on the connecting section 42 of the heat dissipation column 4. Therefore, after the heat dissipation column 4 is installed in the roller body 1, during the working process of the plate roller, the temperature of the coolant can be transmitted through the cooling pipe 421 to achieve cooling and heat dissipation of the surface of the roller body 1, thereby extending the service life of the roller body 1; 2. After the heat dissipation column 4 is installed in the installation groove 12, when the right side of the heat dissipation column 4 is against the limit plate 13, the position of the heat dissipation column 4 in the roller body 1 can be determined, so that the cover plate 5 and the limit plate 13 cooperate to limit the position of the heat dissipation column 4 in the roller body 1 to the left and right, and because the right positioning section 31 will be inserted into the right installation section 43, the heat dissipation column 4 cannot rotate relative to the roller body 1 so that it is stably located in the roller body 1.

[0031] Among them, the cooling pipe 421 includes a left connecting section 4211 and a right connecting section 4212, and the heat dissipation column 4 is provided with a left connecting groove 44 and a right connecting groove 45 for the left connecting section 4211 and the right connecting section 4212 to be inserted. Since the left connecting section 4211 and the right connecting section 4212 will be respectively inserted into the left connecting groove 44 and the right connecting groove 45 of the heat dissipation column 4, after the cooling pipe 421 is installed on the heat dissipation column 4, at this time, since the left connecting section 4211 and the right connecting section 4212 are respectively inserted at different positions of the heat dissipation column 4, the position of the cooling pipe 421 on the heat dissipation column 4 is determined, which provides convenience for the fixation of the cooling pipe 421 and the heat dissipation column 4.

[0032] Among them, the cover plate 5 is provided with a plurality of mounting blocks 51 at intervals along the circumferential direction toward the right, and the roller body 1 is provided with mounting slots 15 corresponding to each positioning block 11. After the cover plate 5 is installed on the roller body 1, each positioning block 11 will be located in the corresponding mounting slot 15 respectively. Therefore, the cover plate 5 cannot rotate compared with the roller body 1, thereby providing convenience for the positioning of the cover plate 5 and the roller body 1 during assembly.

[0033] Among them, it also includes a bolt (not shown in the figure), the roller body 1 is provided with a socket 16, and the right mounting section 43 is provided with a screw hole 431 corresponding to the socket 16. Since the bolt is inserted into the socket 16 and threadedly matched with the corresponding screw hole 431, the bolt can stably connect the right mounting section 43 to the roller body 1 and thus enable the heat dissipation column 4 to be stably connected to the roller body 1.

[0034] Preferably, each of the positioning plug blocks 11 is recessed inwardly and provided with a limiting slot 511, each of the limiting slots 511 is arranged in a ring shape, and the roller body 1 is provided with a limiting plug block 17 in each installation slot 15. Due to the existence of the upper limit slot 511 of each positioning socket 16, when the limiting plate 13 and the roller body 1 are assembled together, the part of each positioning plug block 11 located on the right side of the limiting slot 511 will first squeeze the limiting plug block 17 when inserted into the corresponding installation slot 15, and then forcibly pass over the corresponding limiting plug block 17. 7 so that the limiting slots 511 of the positioning socket 16 cooperate with the limiting plugs 17, and each positioning plug 11 will not be separated from the corresponding installation slots 15 without the action of external force, so as to achieve a stable connection between the cover body and the roller body 1. When the cover body needs to be removed from the roller body 1, a leftward force is applied to the cover body so that the part of each positioning plug 11 located on the right side of the limiting slot 511 moves to the left and forcibly passes over the corresponding limiting plug 17 to achieve the separation of the positioning plug 11 from the installation slot 15, so that the cover plate 5 can be removed from the roller body 1.

[0035] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
