Problems solved by technology

(1) Although the normal log materials are degreased and dried, and then processed, the log door leaves produced in this way will appear cracks after seasonal changes, that is, the door imitation and crosspieces and other places will expand or shrink. Phenomenon, cracks on the paint surface, forming traces, especially in the cold north, the phenomenon is particularly prominent, affecting the overall appearance of the log door leaf
(2) From the perspective of the process flow, the process requires a long production cycle. After analysis, the most difficult operation is the operation of the paint, because it takes a long time for the paint to dry, so it needs to wait, so during this period the factory Employees have to stop production, which affects production efficiency and increases costs over time
(3) However, in the production process, the refinement of the paint is often neglected. Due to improper handling of the paint, the paint on the surface of the produced door often falls off and delaminates, which seriously affects the appearance and use

Embodiment approach 1

[0038] 1) Preparation: Spray a layer of primer on the plates used to prepare the door frame and door core, and set aside;

[0039] 2) Sanding operation: Use a sanding machine to sand and polish the surface as a whole, and the surface of the material is required to be smooth and flat;

[0040] 3) Coloring and rolling bottom treatment; roll coating a layer of unsaturated resin paint on the surface of the board as the top coat for oxygen barrier curing treatment, the time is 40-60 minutes, and the unsaturated resin paint can be operated with PV paint and UV paint ,spare;

[0041] 4) Film: In order to prevent the surface of the product from being damaged, a protective film is pasted on the finished plate to prevent the finished product from being damaged when trimming and assembling accessories;

[0042] 5) Edge trimming: trim the above-mentioned finished panels according to the geometric dimensions of the door leaf and the door cover;

[0043] 6) Assembling operation: glue and ...

[0046] However, in the production process, the detailed treatment of the paint is often neglected. Due to improper handling of the paint, the paint on the surface of the produced door often peels off and delaminates, which seriously affects the appearance and use. In order to solve these problems the present invention also provides a kind of improvement on above-mentioned technology basis, and its specific technology is:

[0047] 1) Preparation: Spray a layer of resin paint on the board used to prepare the door frame and door core as an oxygen-barrier curing primer, such as unsaturated resin paint, and then dry it for 40-60 minutes. Standby;

[0048] 2) Sanding operation: use a sanding machine to sand and polish the surface as a whole, and the surface of the material is required to be smooth and flat;

[0049] 3) coloring and rolling bottom treatment; after the above operations, it is necessary to roll one layer of UV paint on the surface of the plate as a primer;

Abstract

The invention discloses a manufacturing process of a wood door, which is characterized by comprising preparation, sanding operation, colorizing and bottom rolling treatment, lamination, trimming treatment, assembling operation, decorative and shaping fastening piece installation and final entire packaging. The process prevents expansion and contraction in door vertical frame, cross beam and other places. In the invention, the surface oil paint stripping and layering can be prevented by adopting half drying operation, paint spraying, a thermal leveling process and overall drying operation, time is saved and product quality is improved. At the same time, the invention also provides a half drying machine for half drying operation.

Description

technical field [0001] The invention relates to a process for making a wooden door, specifically including a process for making a wooden door and a semi-drying machine for realizing the process. Background technique [0002] The fashionable and elegant characteristics of wooden doors have become the first choice for home decoration. The traditional preparation method is to process the wood into door stands and crosspieces, and then assemble the door standforms and crosspieces into door blanks, and then form door blanks. Paint throughout. (1) Although the normal log materials are degreased and dried, and then processed, the log door leaves produced in this way will appear cracks after seasonal changes, that is, the door imitation and crosspieces and other places will expand or shrink. Phenomenon, cracks on the paint surface, forming traces, especially in the cold north, the phenomenon is particularly prominent, affecting the overall appearance of the log door leaf. (2) From...
