Internal spraying device and method for pop-top can

Abstract

The invention relates to an internal spraying device and method for a pop-top can. A goods feeding part is arranged obliquely above a pre-rotating mechanism, and a goods sliding inlet is formed in thegoods feeding part; a goods discharge part is arranged obliquely below the pre-rotating mechanism, and a goods sliding outlet is formed in the goods discharge part; the pre-rotating mechanism comprises a transfer disc and sucking discs, the transfer disc is connected to the side part of a mounting plate, the sucking discs are annularly arranged on the transfer disc, and a goods carrying shaft hole is formed in the center of the transfer disc; a goods carrying mechanism comprises a goods carrying disc and a goods carrying shaft, and the goods carrying disc is connected with the goods carryingshaft hole through the goods carrying shaft; a spraying mechanism is arranged on the outer side of the goods carrying mechanism, an adjusting port is formed in the inner side of a spraying gun base, an adjusting block is arranged in the adjusting port, a spraying gun chassis is connected with the adjusting block, and a paint spraying gun is connected with the spraying gun chassis and faces towardsthe goods carrying mechanism; and a waste collecting mechanism comprises a paint suction port and a waste collecting box, an opening of the paint suction port faces towards the interface of the goodscarrying mechanism and the spraying mechanism. Spraying can be carried out in the high-speed rotating state of can bodies, coatings are more uniform, and paint consumption is reduced on the premise of ensuring quality.

Description

technical field [0001] The invention relates to an internal spraying device and method of pop cans, and relates to the technical field of pop can production. Background technique [0002] With the vigorous development of the pop can market, the demand for pop cans is increasing year by year, and the competition in the industry is becoming increasingly fierce, which prompts pop can production plants to continuously improve the production efficiency of pop cans and reduce production costs in order to have stronger market competitiveness. This equipment is put into operation under this background And born. [0003] In the traditional can spraying scheme, one-time spraying is usually used. It is difficult to take into account all corners of the inner surface of the can in one spraying process. During the spraying process, the can body of the can cannot be rotated at high speed, which may easily cause uneven spraying. In addition, the excess paint during the spraying process is ...

Problems solved by technology

[0003] In the traditional can spraying scheme, one-time spraying is usually used. It is difficult to take into account all corners of the inner surface of the can in one spraying process. During the spraying process, the can body of the can cannot be rotated at high speed, which may easily cause uneven spraying

In addition, the excess paint during the spraying process is likely to cause pollution to the can body and the environment. The adaptability of different specifications of cans is poor, and it is impossible to quickly switch between different types of cans in production, resulting in low production efficiency.
