Technical Field

The invention relates to the technical field of calendering and molding of PVC materials, in particular to the field of a PVC decorative material production line integrating multi-layer glue-free composite embossing of PVC base material raw materials.

Background

In order to protect the environment and save the cost, the decoration material of the home decoration appliance generally adopts PVC decoration surface to replace the original natural grains on the surface of the decoration material such as log, etc., the fiber board or the shaving board made of secondary wood is used as the base material, the surface of the base material is adhered with the PVC film printed with natural grains as the main body and is embossed to be used as the decoration material. For example, patent document CN103707608B provides a continuous production device for PVC decorative film multilayer non-adhesive composite embossing, i.e. a processing device for producing the PVC film facing material.

The processing device belongs to a mature PVC multi-layer (two-layer or three-layer) glue-free composite embossing machine at present, belongs to equipment for processing PVC decorative films, and can produce thin raw materials with the thickness of about 0.5 mm. The application of two-layer and three-layer compounding is more according to the conventional compounding process and the actual requirement, and the PVC reel base material is discharged through three double-position machine frames during production. The thickness of the third layer (base layer) from the material placing frame is added with the thickness below 0.5mm, the composite material is mainly used as a furniture edge sealing strip and a material with specific thickness, and is applied by combining a surface layer and a printing layer aiming at the decoration and finishing material of the plastic veneer in the furniture door industry. The second layer with the thickness of 0.03-0.06 mm is a veneer printing layer and mainly used for embodying the visual decoration effect of various wood grains and stone grain veneers of the home industry decoration material. The first layer is that surface course material thickness is at 0.03 ~ 0.05mm, and the main effect of surface course is transparent wearing layer, for the scratch resistance of protection veneer and the effect of friction fastness, still keeps the printing veneer definition on second layer simultaneously. The PVC multi-layer composite reel material is characterized in that a multi-layer composite machine steel roller is used for heating the surfaces of a base layer, a printing layer and a surface layer PVC material by adopting heat conduction oil to be activated, the surfaces of the base layer, the printing layer and the surface layer PVC material uniformly enter a guiding and pressing part to be pressed into a layer, then the material enters a multi-roller to be subjected to positive and negative rotation under the condition of adjusting the temperature to realize the hardening and tempering, then the material enters an embossing preheating area to be subjected to the embossing process to finish the embossing process, and after the compounding and embossing process, the material is cooled, drawn, trimmed and reeled to finish the production of the PVC multi-layer composite reel material.

The main organization structure and the process flow of the existing equipment are as follows: 1. the material discharging part comprises three groups of double-position material discharging and changing units, namely a bottom layer, a printing layer and a surface layer; 2. three groups of preheating ironing rollers and compound machine group parts; 3. hot refining and tempering parts of a multi-roller hot homogenizing roller; 4. the surface is heated and embossed; 5. a multi-roll cooling section; 6. drawing the trimming part; 7. a double-station automatic coiling part; 8. the boiler or the electric energy heat supply part completes the whole production process flow.

However, the existing processing equipment and production process are suitable for producing PVC decorative films with the thickness of about 0.5mm, and when the thickness is required to be thicker, for example, more than 1mm, the processing equipment and the production process are difficult to meet the requirements for producing sheet-shaped and plate-shaped PVC decorative materials. When the processing thickness exceeds 1mm, the existing polymer processing technology generally adopts extrusion forming or compression molding, but the extrusion forming can not process patterns, and the production efficiency of the compression molding is low. For this reason, the inventor intends to follow the technical route of calendering and molding by the current PVC decorative film embossing machine and to modify the same so as to adapt to the processing of thicker sheet-shaped PVC decorative materials.
