Plastic sign brushing ink sprayer

Abstract

The invention relates to the technical field of plastic product machining equipment, and discloses a plastic sign brushing ink sprayer. The plastic sign brushing ink sprayer comprises an ink box. An ink outlet pipe is arranged on the ink box and provided with a pressure limiting valve. The ink outlet pipe is connected with a spray head. The ink box is provided with two elastic layers. A threaded rod is arranged between the two elastic layers in a penetrating manner and is provided with a forward thread area and a reverse thread area. First threaded sleeves are arranged at the two ends of the threaded rod and located on the outer side of the ink box. An air inflation ball is arranged at the position, in the ink box, of the threaded rod. Second threaded sleeves are arranged at the positions, on the two sides of the air inflation ball, of the threaded rod. An air inflation pipe is arranged on the air inflation ball. A spray barrel is arranged on the outer side of the spray head. Supporting pipes and ink cleaning pipes are arranged on the spray barrel. A steel wire is mounted in each supporting pipe. The end, close to the ink box, of each supporting pipe communicates with the air inflation pipe. Each ink cleaning pipe is filled with a sponge. Multiple ink suction holes are formed in the face, facing the center axis of the spray barrel, of each ink cleaning pipe. By means of the plastic sign brushing ink sprayer, the problem that the portions, needing no sign brushing, of plastic products are contaminated can be solved.

Description

technical field [0001] The invention relates to the technical field of plastic product processing equipment, in particular to a plastic brush label inkjet. Background technique [0002] Plastic is a class of plastic synthetic polymer materials. Together with synthetic rubber and synthetic fibers, it forms the three major synthetic materials that are indispensable in today's daily life. Specifically, plastic is a material with natural or synthetic resin as the main component, adding various additives, which can be molded into a certain shape under certain temperature and pressure conditions, and can maintain the same shape at room temperature. Compared with metal, stone, wood and other materials, plastic has the advantages of low cost and strong plasticity. It is widely used in the national economy. The plastic industry occupies an extremely important position in the world today. Over the years, the production of plastic products has developed rapidly all over the world. . ...

Problems solved by technology

[0003] When manufacturing plastic products, it is necessary to print marks on the surface of plastic products to achieve the purpose of distinguishing plastic products. When printing on the surface of plastic products, usually use a mark brush to brush the plastic products. However, using the mark When brushing the label, since the brush head has no limit protection, the ink on the brush head is easy to disperse and drip on other parts of the plastic product, thereby polluting the part of the plastic product that does not need to be marked and affecting the appearance of the plastic product
