Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 4, the present invention provides a printing roller for printing plastic packaging bags, which comprises:

a printing roll for plastic packaging bag printing, as shown in fig. 1, comprising: the device comprises a roll shaft 1, wherein a first gear 11 is fixedly sleeved at one end of the outer surface of the roll shaft 1, a first fixing position 12 is arranged on one side, close to the first gear 11, of the outer surface of the roll shaft 1, a second gear 14 is fixedly sleeved at the other end of the outer surface of the roll shaft 1, and a second fixing position 13 is arranged on one side, close to the second gear 14, of the outer surface of the roll shaft 1; the outer surface of the roller shaft 1 is fixedly sleeved with a roller body 2 between the first fixing position 12 and the second fixing position 13.

Specifically, as shown in fig. 2, the outer surface of the roller body 2 is uniformly welded with a plurality of connecting rods 21, each connecting rod 21 is provided with at least one inverted step-shaped ring on the outer surface, and the inverted step-shaped rings arranged on the surfaces of the connecting rods 21 can prevent the connecting ring 31 from falling off, so that the printing block 3 is damaged.

Specifically, as shown in fig. 2 and 3, there is printing piece 3 at connecting rod 21 top through quick detach mechanism swing joint, printing piece 3 still includes go-between 31, stamp district 32, go-between 31 sliding connection is in printing piece 3 bottom, printing piece 3 is in each through go-between 31 swing joint connecting rod 21 is outside, each the stamp district 32 sculpture content at printing piece 3 top is all inequality, connects the printing piece 3 of carving different printing patterns through a plurality of connecting rods 21, makes the printing content more nimble.

Specifically, as shown in fig. 1, the roller 1 is located first fixed position 12, the fixed 13 both sides of second and has all welded the spacing ring, first fixed position 12, the fixed 13 inside of second and all be provided with at least one ball bearing between the roller 1, the spacing ring can prevent that roll body 2 during operation from taking place the displacement of horizontal direction, causes the printing pattern to warp, influences printing quality, and ball bearing can weaken the friction between roller 1 and first fixed position 12, the fixed 13 of second, reduces wearing and tearing.

Specifically, as shown in fig. 3, the outer surface of the connection ring 31 is provided with anti-slip lines, so that friction between a hand and the connection ring 31 when the printing block 3 is detached is increased, and slipping is prevented.

Specifically, as shown in fig. 2, the transverse and longitudinal length dimensions of the printing area 32 are equal to half of the distance dimension between two adjacent connecting rods 21, and after the printing blocks 3 are mounted on the connecting rods 21, a smooth overall curved surface is formed between the printing blocks 3, so that the printing blocks 3 cannot rotate along the axial direction of the connecting rods 21, and printed patterns cannot rotate or twist.

The working principle is as follows: when the printing plate roller is used, the first fixing position 12 and the second fixing position 13 are fixed in a reserved plate roller clamping groove of equipment, the first gear 11 and the second gear 14 are meshed with a power gear of the equipment, the printing block 3 is connected to the connecting rod 21 through the quick-release structure according to the content to be printed, starting printing can be conducted after the printing is completed, when the printing content is changed, only the machine is stopped to replace the changed printing block, the whole plate roller does not need to be replaced, various plate rollers do not need to be manufactured to print different contents, the cost is saved, the time for replacing the plate roller is reduced, and the working efficiency is greatly improved.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
