Automatic production process of special-shaped strip

Abstract

The invention relates to the technical field of a special-shaped strip and particularly relates to an automatic production process of the special-shaped strip. The automatic production process comprises the following steps of: A, extruding: adding raw materials into extrusion molding equipment to be extruded and molded to prepare a special-shaped strip primary product; B, cooling: introducing the special-shaped strip primary product into cooling equipment to be cooled and sized; C, drawing: drawing the special-shaped strip primary product by drawing equipment; D, drying: carrying out drying treatment on the special-shaped strip primary product; E, covering: carrying out protection layer covering on the special-shaped strip primary product by a covering machine to obtain a special-shaped strip semi-finished product; and F, cutting: cutting the special-shaped strip semi-finished product according to a needed specification size to prepare a special-shaped strip finished product. According to the automatic production process of the special-shaped strip disclosed by the invention, the production is integrated, raw materials are saved, the production cost is reduced, secondary heating is avoided, 20-30% of heat is saved and the production efficiency is improved to be more than 3 times of the previous production efficiency. The special-shaped strip prepared by the invention has good quality, the size stability is improved by 5-10% and the stripping strength of a protection layer and a substrate is improved by 10%.

Description

technical field [0001] The invention relates to the technical field of special-shaped strips, in particular to an automatic production process for special-shaped strips. Background technique [0002] With the improvement of people's living standards, people's requirements for home life are getting higher and higher. When modern people decorate interiors, they pay more attention to the overall perfection of decoration in order to beautify the living space in an all-round way. In the current interior decoration, in order to achieve a beautiful and high-end decoration effect, decorative building materials such as baseboards, floor closing strips, wardrobes, door and window frame strips are generally set. Skirting lines and floor closing strips are used to make up the joints of solid wood floors or composite wood floors, or the gaps reserved between the floor and the wall. Using skirting lines or floor closing strips to connect the joints or gaps can protect the The surface mak...

Problems solved by technology

[0003] At present, in the existing preparation process of special-shaped strips, the extruded special-shaped strips need to be cut first, and then coated. After coating each special-shaped strip, there will be more than 1cm of residual material at both ends, which requires Cutting off the remaining material of the coated special-shaped strip again increases labor costs and wastes raw materials

Moreover, after the special-shaped strip is cut, it needs to go through the intermediate link of manual handling, and then wrap it to produce the finished product. The degree of automation of the production line is low, the operation is troublesome, the production efficiency is low, and the labor intensity is increased, and the labor cost increases accordingly. Moreover, the handling process is easy to cool and scratch the special-shaped edge banding strips. When it is to be coated, it needs to be heated twice to ensure the coating effect, which consumes energy and increases the cost of the enterprise. Moreover, the quality of the finished special-shaped strips produced by the second heating is poor, and the product The dimensional stability is low, the peel strength between the protective layer and the substrate is low, it does not meet the production requirements, and it is not suitable for large-scale and efficient automatic production by enterprises
