DETAILED DESCRIPTION

[0026] In order to make the personnel in the technical field better understand the technical scheme in the present application, the technical scheme in the embodiments of the present application will be described clearly and completely in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by the person skilled in the art without creative labor should belong to the scope of protection of the present application.

[0027] As Figures 1 to 5As shown, the utility model discloses a printing roller in one embodiment, including roller body 1, and the connecting block 11 and fixed assembly are installed on roller body 1. The connecting block 11 and fixed assembly are all a pair, and the connecting block 11 of a pair is integrally formed on the opposite side wall of roller body 1.

Locking assembly is installed on fixed block 2, and locking assembly is used for locking connecting block 11 in clamping groove 201, and the device for adjusting the height of connecting block 11 is installed in clamping groove 201. The side wall away from clamping groove 201 of fixed block 2 is fixedly connected with docking assembly, and fixed block 2 is fixedly installed on the rotating shaft of printing device through docking assembly.

[0028] Specifically, locking assembly includes first screw rod 21, and the first screw thread hole 202 matched with first screw rod 21 is formed on fixed block 2, and the pressing plate 24 is rotatably connected on first screw rod 21, and the pressing block 25 matched with clamping groove 201 is integrally formed on the lower end surface of pressing plate 24.

[0029] When replacing roller body 1 on printing device, anticlockwise screwing first screw rod 21 makes first screw rod 21 gradually bolt from first screw thread hole 202, when the lower end surface of pressing block 25 is higher than the end surface of fixed block 2, rotating pressing plate 24, and the slot of pressing block 25 is away from clamping groove 201. At this time, lifting roller body 1 upwards, and connecting block 11 can slide out from clamping groove 201, and clamping groove 201 is in idle state at this time. Then take out the roller body 1 needed to be replaced, and the connecting block 11 on roller body 1 is clamped into clamping groove 201, and rotating pressing plate 24 makes pressing block 25 align with clamping groove 201, and clockwise screwing first screw rod 21, and pressing block 25 gradually slides downwards until pressing connecting block 11 in clamping groove 201, and the replacement is completed.

[0030] In order to conveniently make pressing block 25 slide into clamping groove 201, a pair of inclined surfaces 251 are formed on the lower end surface of pressing block 25. A pair of inclined surfaces 251 make the lower end surface of pressing block 25 form wedge shape, and can guide pressing block 25, even if pressing block 25 does not completely align with clamping groove 201, when first screw rod 21 gradually rotates into first screw thread hole 202, pressing block 25 will automatically adjust its direction.

[0031] In order to make pressing plate 24 rotate on first screw rod 21, as shown, Figures 3 to 5 Fixed block 2 is rotatably connected with sleeve 23, and pressing plate 24 is integrally formed on sleeve 23, and pressing plate 24 rotates around first screw rod 21 through sleeve 23.

[0032] Further, the first screw rod 21 is integrally formed with a pair of limiting plates 22, and opposite side walls of the pair of limiting plates 22 are attached to upper and lower end faces of the sleeve 23. The pair of limiting plates 22 can limit the sleeve 23, and can prevent the sleeve 23 from sliding upward and downward on the first screw rod 21 after being stressed.

[0033] Further, the first screw rod 21 is integrally formed with a pair of limiting plates 22, and opposite side walls of the pair of limiting plates 22 are attached to upper and lower end faces of the sleeve 23. The pair of limiting plates 22 can limit the sleeve 23, and can prevent the sleeve 23 from sliding upward and downward on the first screw rod 21 after being stressed.

[0034] In addition, the connecting block 11 is integrally formed with a baffle 111, and when the connecting block 11 on the two side walls of the roller body 1 is clamped in the clamping groove 201 on the pair of fixing blocks 2, the pair of baffles 111 are attached to the side walls of the fixing blocks 2, respectively, so that the roller body 1 is guaranteed to be in the center position of the printing equipment, and the phenomenon of deviation of the roller body 1 during printing is prevented.

[0035] As shown in Figure 1 , Figure 3 and Figure 5 , the device for adjusting the height of the connecting block 11 includes a second screw rod 26, and the fixing block 2 is provided with a second threaded hole 203 matched with the second screw rod 26, and the second screw rod 26 penetrates through the lower groove wall of the clamping groove 201.

[0036] Specifically, after the roller body 1 is replaced, if the diameter of the roller body 1 at this time is different from that of the last roller body 1 installed in the clamping groove 201, the height of the connecting block 11 in the clamping groove 201 can be changed by rotating the second screw rod 26, so that the second screw rod 26 penetrates through the bottom wall of the clamping groove 201 and protrudes from the bottom wall of the clamping groove 201 to lift the connecting block 11 in the clamping groove 201 upward. By adjusting the distance between the roller body 1 and the non-woven fabric, the depth of the printing pattern is controlled to ensure the printing quality.

[0037] Further, the second screw rod 26 is integrally formed with a rotating disc 261. The clamping groove 201 is slidably connected with a pad 27, and the pad 27 is provided with a rotating groove 271 matched with the rotating disc 261. The rotating groove 271 can increase the contact area between the second screw rod 26 and the connecting block 11, and prevent the pressure between the second screw rod 26 and the connecting block 11 from being too large to damage the connecting block 11.

[0038] In addition, the rotating disc 261 rotates in the rotating groove 271, which can also prevent the connecting block 11 from being damaged by friction when the second screw rod 26 rotates.

Specifically, the fixing disc 3 can be fixed on the rotating shaft of the printing equipment by screwing a bolt through the third threaded hole 301. When the rotating shaft of the printing equipment rotates, the fixing disc 3 rotates to drive the roller body 1 to rotate.

[0040] In use, when the roller body 1 needs to be replaced, the nut 211 on the first screw rod 21 is first unscrewed, and then the first screw rod 21 is unscrewed counterclockwise to move upward in the fixing block 2. When the pressing block 25 is higher than the upper end surface of the fixing block 2, the pressing block 25 is rotated to move away from the slot opening of the clamping groove 201, and then the lower roller body 1 can be removed.

[0041] After the required roller body 1 is replaced, if the diameters of the two roller bodies 1 before and after the replacement are the same, the above-mentioned operation can be repeated in reverse to fix the roller body 1 on the fixing block 2.

[0042] If the diameters of the two roller bodies 1 before and after the replacement are different, first, the second screw rod 26 is screwed according to the diameter difference between the two roller bodies 1 to adjust the height of the gasket 27 in the clamping groove 201, and then the connecting block 11 is placed in the clamping groove 201, the first screw rod 21 is screwed clockwise to press the connecting block 11 with the pressing block 25, and then the nut 211 is tightened.
