Description

TECHNICAL FIELD

[0002] In the printing equipment, the fixing mode of the base plate is crucial to guarantee the printing precision and speed. In the prior art, there are mainly three fixing modes of clamping type, automatic positioning type and air cylinder type. The clamping type fixes the base plate manually through the clamp, which is simple to operate but complex to adjust, is easy to produce errors and has poor stability at high speed printing. The automatic positioning type uses machine to accurately control the position of the base plate, improves the precision and stability and is suitable for high speed printing, but has high cost and needs regular maintenance. The air cylinder type flexibly adjusts the fixing force through the air cylinder pressure and adapts to base plates of different thicknesses, also needs additional cost and maintenance. Therefore, when selecting the fixing mode of the base plate, the printing precision, speed and cost factors need to be considered to find the most suitable fixing method and ensure the ideal printing effect.

[0003] From the above common fixing modes of the base plate in the prior art, it can be found that the fixing method of the air cylinder type is the most flexible, which can adjust the fixing force according to the thickness of the base plate. However, in the printing equipment, only in order to fix the base plate, the air cylinder is used for operation, which inevitably increases the manufacturing cost and maintenance cost of the whole device. The cost of the automatic positioning type is much higher than that of the air cylinder because it uses machine to accurately control the position of the base plate. If the clamping type is used, the fixing force cannot be adjusted according to the thickness of the base plate. Therefore, there is a need for a fixing mechanism which can fix the base plate according to the thickness of the base plate and has low cost and is convenient to maintain. SUMMARY
