Multi-specification automatic chopstick painting equipment and method

Abstract

The invention relates to multi-specification automatic chopstick painting equipment and method. The method comprises the steps of: (1) inserting chopsticks in boards in rows in a vibrating way; (2) supplying the boards in an automatic stepping way and supplying empty boards by pressure; (3) overturning the boards and moving the chopstick boards in a positioning way; (4) vertically immersing in paint and guiding and correcting chopsticks; (5) supplying paint by circulating pressure; and (6) moving the chopstick boards upward and scraping paint off at a rubber opening. The invention has the advantages that one set of equipment can make work load of 26 workers and can replace manual painting operation efficiently, reduce labor intensity and greatly improve labor productive power; the consumption of paint raw material is saved; the length of the blank of the chopstick is shortened; the utilization rate of specification draw material is improved; the bottleneck effect of the output improvement of the chopstick enterprises can be broken down; production output can be improved; product quality can be stabilized; and labor cost and raw material cost can be reduced.

Description

technical field The invention relates to an automatic painting equipment and method for multi-standard chopsticks. Background technique At present, the paint of bleached decal paint chopsticks at home and abroad mainly adopts the production process of manual workshops, and there are mainly the following major problems: low production efficiency, low output, and unstable quality; artificial loss of paint during use; When pulling the paint, the mouth of the paint pot needs to be operated downwards. It is artificially caused that when the chopsticks are pulled out and the next chopstick is not inserted into the paint pot, the paint will flow out from the small rubber mouth and be lost, which is about 300mm per person per day; it is not good for the specifications of the chopsticks. Raw materials are wasted. Conventional finished chopsticks have five specifications: 255mm, 245mm, 240mm, 225mm, and 180mm. The large end of the chopsticks formed by manual operation needs to be left...

At present, the paint of bleached decal paint chopsticks at home and abroad mainly adopts the production process of manual workshops, and there are mainly the following major problems: low production efficiency, low output, and unstable quality; artificial loss of paint during use; When pulling the paint, the mouth of the paint pot needs to be operated downwards. It is artificially caused that when the chopsticks are pulled out and the next chopstick is not inserted into the paint pot, the paint will flow out from the small rubber mouth and be lost, which is about 300mm per person per day; it is not good for the specifications of the chopsticks. Raw materials are wasted. Conventional finished chopsticks have five specifications: 255mm, 245mm, 240mm, 225mm, and 180mm. The large end of the chopsticks formed by manual operation needs to be left 40-50mm long to be held tightly by hand. The chopsticks blank fixture part Too long is unfavorable to the specification of materials, which wastes a lot of raw materials; polyester paint is not environmentally friendly, cannot be dried, and is not conducive to the application of environmentally friendly water-based paint. Most of the paint materials for chopsticks use polyester paint, and the benzene and ketone solvents in the paint volatilize Polyester paint has a great negative impact on the health of operators who work for a long time. There is a phenomenon that it is difficult to recruit paint workers. Polyester paints are not environmentally friendly. Polyester paint chopsticks cannot be dried, which prolongs the time period for the second painting. If environmental protection water-based paint is used as raw material, although it can be dried, each chopstick needs to be painted more than 6 times to meet the requirements. , which greatly increases the labor cost and is not easy to popularize and apply; only when the paint work efficiency is greatly improved can the popularization and application of environmentally friendly water-based paint be possible
