Process for manufacturing injection moulding seal edge of wooden floor or furniture board and edger thereof

Abstract

The invention discloses an edge bander for bonding edges of wooden floor board or furniture board by injecting plastic and a production process thereof. The process comprises the following steps: using the edge bander and the method to place a pre-processed wooden floor board or furniture board into a corresponding mold cavity of an opened forming mold for mold spotting and locking mold, injecting high-temperature melt plastic into hot runners uniformly arranged in heating boards from a main feeding opening, injecting the plastic into the clearance between a forming mold cavity and the periphery of the wooden floor board or the furniture board from taper-shaped feeding ports which are uniformly arranged along the periphery of the forming mold and are provided with cold feeding positions respectively so as to melt and cast the plastic and the wood fiber into a whole, then cool the whole body, and make an edge banding product demould from a front mold and a back mold respectively through pneumatic and mechanical demolding. The edge bander and the process not only ensure the good quality of banding wooden floor board or the furniture board by using plastic, high strengthen of adhesion, long service and uneasy falling, but also realize mechanized one-time forming, rapid edge banding and enable the edge banding plastic and a plate material for edge banding to form a whole body with stable and reliable quality.

Description

technical field [0001] The invention relates to a manufacturing process of injection molding edge banding of wooden floor or furniture board and an improved injection molding edge banding machine thereof, in particular to a manufacturing process of wooden floor or furniture board injection molding edge banding and the edge banding machine. Background technique [0002] The traditional edge banding of wooden floors and veneered furniture panels is to process the edge banding materials into finished products or emulsions, and then use adhesives to bond or use emulsions to brush around wooden floors and veneered furniture panels to achieve edge banding. Moisture-proof, beautiful effect. [0003] Traditional solid wood flooring, bamboo wood flooring, laminate flooring, and multi-layer solid wood flooring are processed into tenon and groove joints, and then the tenon and groove joints are sealed and edged with waterproof paint or natural oil. In this way, the edge sealing treatm...

AI Technical Summary

Problems solved by technology

In this way, the edge sealing treatment cannot fully achieve the effect of moisture resistance, and its defects:

[0004] 1. Apply paint or oil essence once or twice, because the well-fitted mortise and groove can only be painted once or twice, and the waterproof membrane is only 0.03mm to 0.08mm. Can't be sealed, can't achieve the effect of edge sealing and moisture-proof

[0005]2. When processing wooden floor mortise and groove joints, whether it is a tenon or a tenon, it has an inner angle of about 90°. When painting, the inner angle is painted The layer is extremely uneven. When painting the mortise and groove, due to the complex shape of the mortise and groove, there is currently no equipment that can evenly coat the paint on the floor mortise and groove. It can only be painted manually or manually. spraying

Therefore, the waterproof edge sealing treatment of the tenon and groove joints of the wooden floor can only be a form, and it does not achieve the effect of moisture resistance

[0006]3. After the 0.03mm to 0.08mm thick waterproof coating of tenon-and-groove joints is assembled together on the floor, due to a certain height difference on the floor, people on the floor When walking up, there will be friction between the tongue and groove, only 0.03mm to 0.08mm thick waterproof coating will be worn away in a short time, and the effect of edge sealing and moisture resistance will not be achieved.

[0007]4. When paint or natural oil seals the edge of the floor, it not only pollutes the environment, but also takes a lot of work and time, and cannot fully achieve the effect of sealing the edge against moisture. Effect

[0009] The edge banding of traditional veneer furniture boards is to process plastic edge bands, metal edge bands, etc. into required width and thickness and different shapes of edge bands, and then use a hot-melt edge banding machine to bond the edge bands Adhesives are also used to seal the edges of the veneer furniture boards. This method of edge sealing: A. The speed is slow; B. The bonding strength is not good and it is easy to fall off; C. The edge banding has The joint cannot be completely sealed, and it also affects the appearance and moisture-proof effect; D. Waste materials and pollute the environment
