Description

Six-freedom-degree adjustable hot melt adhesive coating die head

Technical Field

The utility model relates to the technical field of hot melt adhesive coating equipment, in particular to a six-degree-of-freedom adjustable hot melt adhesive coating die head.

Background

Hot melt adhesive coating refers to coating a hot melt adhesive in a liquid or semi-solid form on the surface of an object to be bonded, and then cooling and solidifying the hot melt adhesive to achieve bonding. The hot melt adhesive is generally present in a columnar or granular form, is brought into a liquid state by heating at the time of coating, and is then fed into the interior of a coating die, and is uniformly coated on the surface of a web to be coated by manual or automatic control by aligning the coating port of the coating die with the surface of the web to be coated. After the coating is completed, the hot melt adhesive is rapidly cooled and solidified in a short time.

At present, when coating is carried out by utilizing a coating die head, as the coated coiled material can deviate in the conveying process, the position of the current coating die head is single, and corresponding position adjustment is generally difficult to be carried out aiming at the deviation of the coiled material, so that a conveying line can only be prolonged, and a deviation correcting mechanism aiming at the conveying of the coiled material is additionally arranged in the front of hot melt adhesive coating to ensure the coating position of the coiled material, but the following problems exist in the solution mode:

1. Because the coating die head cannot move transversely, when the coiled material deviates too much, the coiled material is adjusted by using the deviation correcting mechanism, so that the deviation correcting mechanism easily exceeds the adjustment limit, the coated thermosol side leaks out of the coiled material, and even is adhered to the conveying roller, and the coating quality of the coiled material is reduced;

2. the adopted deviation correcting mechanism not only increases the length of the production line, but also needs frequent maintenance and repair, increases the cost, and reduces the coating processing efficiency.

In summary, there is a need for a coating control system having multiple degree of freedom adjustments to a coating die.
