Ink supply device, pad printing machine comprising same and control method thereof

Abstract

The invention provides an ink supply device, a pad printing machine comprising the same and a method for controlling the ink supply device, which are used for pad printing operation for coating surfaces of plastic toys and the like, realize coating of the toys with large change of curves, can overcome shortcomings of traditional pad printing equipment, and improve production efficiency and guarantee coating quality. The ink supply device comprises an ink supply box with an internal cavity, an ink opening communicated with the cavity is arranged on the top of the ink supply box, and the ink supply device is further provided with a squeezing device used for squeezing out ink in the cavity to the ink opening. The pad printing machine with the ink supply device comprises the ink supply device, a pad printing head component, a pad printing head transmission component, a plastic part fixing component, a control unit and a framework, the pad printing head component is used for printing a plastic part to be printed, the pad printing head transmission component is used for moving the pad printing head component, the plastic part to be printed is fixed by the aid of the plastic part fixing component, the ink supply device, the plastic part fixing component, the pad printing head transmission component and the control unit are mounted on the framework, and the pad printing component is mounted on the pad printing head transmission component.

Description

technical field [0001] The invention belongs to the field of toy production technology and automation technology, and in particular relates to an ink supply device, a pad printing machine using the ink supply device and a control method thereof, which are used for pad printing of plastic toy surface coating. Background technique [0002] Plastic toys are a variety of products with large changes in appearance, and each style of toy has its unique appearance and structure. Especially in the toy surface coating process, due to the complexity and diversity of product positions, it is necessary to use a large number of pad printing equipment to paint different patterns and colors on the toy surface. [0003] The principle of pad printing equipment is to etch the required pattern and text shape on the metal lithography to form a depression, then apply ink on the metal lithography, and then use a scraper to scrape off the ink outside the depression, and use a soft rubber head to pr...

AI Technical Summary

Problems solved by technology

The pad printing equipment mentioned above is only suitable for occasions where the pattern area is small and the surface of the toy is flat and uniform. When encountering a toy product with a large area and a large change in the surface surface, it is difficult to apply ink with good quality on the pad printing plate, so it cannot be guaranteed Painting quality

In this way, manual spraying can only be used to replace the pad printing process. However, manual spraying also has obvious disadvantages: the proficiency and fatigue of the operator will directly affect the production efficiency and spraying quality, making it difficult to control the production progress, and the deviation of spraying techniques A lot of spray paint will be wasted, which will increase the cost; at the same time, intensive manual spraying stations will pose potential risks to employee health and environmental protection. With the development of the economy, labor costs will become higher and higher, which will also push up manual spraying. the cost of

However, there is no pad printing equipment suitable for the characteristics of toy production, which greatly limits the development of the toy industry.
