As shown in fig. 1-3, a printing roller with a plate locking device provided in an embodiment of the present utility model includes a printing roller 1, a pin offset, a plate reeling roller 3, and a plate locking device 4, wherein a mounting hole 11 and a first bayonet slot 12 are formed on the circumferential surface of the printing roller 1 in the axial direction thereof, and as shown in fig. 2, the mounting hole 11 and the first bayonet slot 12 are arranged side by side with each other, and an opening 111 is formed on the mounting hole 11, and the width of the opening 111 is smaller than the diameter of the mounting hole 11 and smaller than the diameter of the plate reeling roller 3, so that the plate reeling roller 3 is prevented from falling out through the opening 111 in the mounting hole 11 when the plate reeling roller 3 is mounted in the mounting hole 11. The plate roller 3 is rotatably arranged in the mounting hole 11 and is provided with a second bayonet slot 31; the printing offset plate 2 is wrapped on the circumferential surface of the printing roller 1 in a winding manner, and clamping blocks 21 are arranged at two edges of the printing offset plate, namely, clamping blocks 21 are arranged on two edges which are parallel to the axis of the printing roller 1, one clamping block 21 is clamped in the first bayonet slot 12, and the other clamping block is clamped in the second bayonet slot 31. The plate locking device 4 is arranged at the end part of the plate roller 3 and comprises a ratchet wheel 41 and a rack 42 matched with the ratchet wheel, wherein the record is fixedly arranged on the end part of the plate roller 3, the rack 42 and the ratchet wheel 41 are correspondingly arranged at the end part of the printing roller 1, pawl teeth 421 matched with the ratchet wheel 41 are arranged on the surface of the rack 42 facing the ratchet wheel 41, one end of the rack 42 is rotatably connected on the end part of the printing roller 1 through a pin 422, and the other point is provided with an elastic support facing the direction of the ratchet wheel 41, so that the rack 42 and the ratchet wheel 41 are kept in an engaged state. Through the above-mentioned structure, under the mutual cooperation of ratchet 41 and pawl tooth 421, make ratchet 41 and the roll plate roller 3 only have single direction of rotation, that is, under the cooperation of ratchet 41 and rack 42 of intermeshing, only have the direction of going on rotating towards first bayonet socket 12, at this moment, through printing offset plate 2 joint on second bayonet socket 31 one end will twine on roll plate roller 3 through fixture block 21, thereby make printing offset plate 2 cladding portion and the mutual laminating between printing roller 1 closely, the installation is firm, simultaneously, because roll plate roller 3 rotates in mounting hole 11, thereby can twine the printing offset plate 2 of cladding on printing roller 1 closely with it, at this moment, can prevent effectively that fixture block 21 breaks away from in first bayonet socket 12 or second bayonet socket 31, can guarantee printing offset plate 2 installation stability, because with the rack 42 of ratchet 41 joint under the effect of elastic support, thereby can prevent that the roll plate roller 3's of wrapping up in production from laminating each other closely with each other, can prevent that printing offset plate roller 3's the situation can not appear firm, can not guarantee the printing offset plate 2's that the printing accuracy can appear in the course. It will be appreciated that when the printing blanket 2 needs to be replaced, only the rack 42 needs to be supported against the resilient support so that the rack 42 rotates along the pin 422, thereby causing the pawl teeth 421-the ratchet wheels 41-to disengage from each other so that the plate roller 3 can be reversed, so that the printing blanket 2 and the printing roller 1 can be released from each other, and the clamp block 21 can be removed from the first bayonet slot 12 and the second bayonet slot 31, and the printing blanket 2 can be removed and replaced.
In use, one clamping block 21 of the printing plate 2 is clamped in the first bayonet groove 12 above the printing roller 1, the other clamping block 21 is clamped in the second bayonet groove 31 above the plate roller 3, during the rotation of the plate roller 3 in the mounting holes 11, the printing plate 2 can be wound on the plate roller 3, so that the printing plate 2 coated on the printing roller 1 can be tightly abutted on the printing roller 1, simultaneously, under the cooperation of the ratchet wheel 41 and the rack 42 of the plate locking device 4, the plate roller 3 can only rotate towards one direction towards the first bayonet groove 12, namely, the printing plate 2 can only be wound on the plate roller 3, so that the printing plate 2 can be tightly mounted on the printing roller 1, and meanwhile, the rack 42 is supported by elasticity to keep engaged with the ratchet wheel 41, so that the ratchet wheel 41 can be locked and prevented from overturning, namely, the printing plate 2 is locked on the printing roller 1. The printing offset plate 2 can be conveniently and rapidly disassembled and assembled through the structure, and the mounting firmness and compactness of the printing offset plate 2 can be ensured when the printing offset plate 2 is mounted on the printing roller 1, so that the printing quality is ensured.
Further, in the machining process, the first bayonet slot 12 and the second bayonet slot 31 are provided with dovetail structures, and accordingly, the clamping block 21 is also provided with dovetail structures, and by the above structure, the clamping block 21 can be firmly clamped in the bayonet slots.
As shown in fig. 1 and 3, a shoulder 411 is formed on the end surface of the ratchet wheel 41 facing away from the printing roller 1, and as shown in fig. 3, the diameter size of the shoulder 411 is smaller than the diameter size of the root circle of the ratchet wheel 41, meanwhile, a mounting seat 43 matched with the ratchet wheel 41 is arranged on the end surface of the printing roller 1, and a hole site 431 for rotationally connecting the shoulder 411 is formed on the mounting seat 43, wherein the hole site 431 is in communication with the mounting hole 11. The end of the plate roller 3 is rotationally connected onto the mounting seat 43 through the ratchet wheel 41, and the mounting seat 43 is fixedly connected onto the end of the printing roller 1, so that the plate roller 3 can rotate stably in the mounting hole 11, and the condition of movement and shaking cannot occur.
Meanwhile, the size of the mounting hole 11 is set, specifically, the radius size is larger than the sum of the radius size of the plate roller 3 and the thickness size of the printing offset plate 2, so that enough space is provided in the mounting hole 11 for accommodating the printing offset plate.
As shown in fig. 3, to ensure the stability of the plate roller 3, two plate locking devices 4 are provided, which are respectively located at two ends of the plate roller 3.
The embodiment of the present utility model also gives a specific example of a specific structure of the elastic support, as shown in fig. 3, a spring seat 44 is fixedly installed on the end face of the printing roller 1 and below the rack 42, a mounting hole 441 is provided on the surface of the spring seat 44 facing the rack 42 for mounting one end of a spring 45 therein, and the other end of the spring 45 protrudes toward the rack 42 and abuts against the bottom of the rack 42, thereby providing a force to the rack 42 in a size facing the ratchet 41 direction, so that the pawl is continuously engaged with the ratchet 41.
In this embodiment, since the rack 42 can be assembled with the ratchet 41 in a mutually matched manner under the action of the spring 45, the spring force of the spring 45 can be overcome in the process of rotating the ratchet 41, so that the rotation of the ratchet 41 is limited by the pawl when the printing blanket 2 is turned over, and the printing blanket 1 is locked on the printing roller 1.
Various other corresponding changes and modifications will occur to those skilled in the art from the disclosure herein, and all such changes and modifications are intended to be included within the scope of the present utility model.
