Description

Technical Field

[0001] The invention relates to the technical field of paint production, in particular to an automatic cap placing device for paint production. Background Art

[0002] Paint is a chemical mixture coating that can be firmly covered on the surface of an object for protection, decoration, marking and other special purposes. The book "Coating Technology", which is relatively authoritative in the Chinese coating industry, defines it as follows: "Coating is a material that can be applied to the surface of an object using different construction processes to form a solid film that is firmly adhered, has a certain strength, and is continuous. The film formed in this way is generally called a coating film, also known as a paint film or a coating."

[0003] At present, after the paint is filled, the paint can needs to be capped and sealed. Before the capping, the paint can cover needs to be placed on the top surface of the paint can. However, the practice in the prior art is: the paint can filled with paint is placed on a conveyor belt, and then the cover is manually placed on the paint can, and then it is conveyed to the next step of capping processing. However, the manual operation not only has a low degree of automation, but also has a relatively high labor cost in long-term production, which is not conducive to large-scale production of enterprises. Secondly, the workers have subjective consciousness in operation. If they are in a bad mental state, the quality of capping will be reduced (deviation will occur), which will greatly affect the subsequent capping quality, thereby increasing the defective rate of the product; based on this, we propose an automatic capping device for paint production Summary of the invention

When working, the first private service motor 23 and the first reduction motor 24 are started first, thereby driving the first synchronous pulley 25 to work, and then synchronously driving the first moving rod 7 and the second moving rod 8 to rotate. When the first moving rod 7 and the second moving rod 8 rotate, they can drive the first moving part 9 and the second moving part 10 to clamp inwards or loosen outwards (the synchronized third moving part 11 and the fourth moving part 12 clamp inwards or loosen outwards), thereby driving the first clamping part 23 and the first reduction motor 24 to work.
