Detailed Description

As shown in fig. 1 and 2, a printing roller comprises a connecting rod 1, wherein an inner roller body 20 is fixedly connected to the middle position of the connecting rod 1, a group of mirror symmetry positioning holes 22 are formed in the front side and the rear side of the inner roller body 20, and an outer roller body 30 is fixedly connected to the outer portion of the inner roller body 20.

Referring to fig. 2, the outer roller 30 is composed of two mirror-symmetrical half roller bodies 31, the two half roller bodies 31 are arc-shaped, a pair of inserts 32 are fixedly connected to the middle positions of opposite sides of the half roller bodies 31, and when in use, the two half roller bodies 31 are inserted into the corresponding positioning holes 22 through the inserts 32 respectively, so that the outer roller body 30 is mounted outside the inner roller body 20. When in use, different outer roller bodies 30 can be replaced according to different printing patterns, so that the effect that the same printing roller can print various patterns is achieved, and if the surface of the outer roller body 30 is damaged, only a new outer roller body 30 or a half roller body 31 on the damaged side is needed to be replaced, so that the damage and replacement cost is greatly reduced.

Referring to fig. 2, the left and right sides of the half roll 31 are fixedly connected with arc blocks 33, and a set of fixing holes 34 are formed on opposite sides of the arc blocks 33. The connection between the arc-shaped blocks 33 and the half roller bodies 31 forms an arc-shaped gap, and when the two half roller bodies 31 are connected to the inner roller body 20, the connection between the two arc-shaped blocks 33 and the two half roller bodies 31 is a circular gap.

Referring to fig. 1 and 3, the left and right sides of the connecting rod 1 are provided with mirror symmetry fixing devices 4, and the fixing devices comprise two semicircular blocks 41, and the two semicircular blocks 41 are arranged in a mirror image.

Referring to fig. 4, slots 42 are formed on the right sides of the four semicircular blocks 41, a set of threaded holes 43 are formed on the left surfaces of the four semicircular blocks 41, and threaded nails 44 are connected to the internal threads of the threaded holes 43. When in use, the two semicircular blocks 41 are respectively arranged in a mirror image manner and are inserted into the arc-shaped blocks 33 through the slots 42, the semicircular blocks 41 are rotated to enable the threaded holes 43 to correspond to the fixing holes 34, and the threaded nails 44 are respectively screwed into the fixing holes 34, so that the semicircular blocks 41 are fixed on the half roller body 31.
