Description

Disc type milling cutter for preventing glue overflow during edge sealing of plate

Technical Field

The utility model relates to a plate fitment becomes the processing equipment of producing required panel, especially a disc milling cutter who produces excessive glue when being used for preventing panel banding.

Background

The prior plate-type furniture is widely used and mainly comprises a shaving board, a density board, a multilayer board, an ecological board and the like, wherein the surface of the shaving board, the density board, the multilayer board, the ecological board and the like is provided with a veneer, after cutting, edge finishing is carried out, glue is coated, and then an edge sealing strip is attached.

Due to the fact that the board material physical properties for the panel furniture are different, after the board is cut and sawed, the cut end face is uneven or sawn marks, waves and the like exist, if the edge is directly sealed, the edge sealing strips are difficult to attach, and the phenomenon of obvious glue lines or glue overflow can be caused.

Because the cutting edges of the cutting plate and the sawing tool are sharp, the quality of workpiece surface processing is better because the cutting edges of the cutting tool are sharp when the cutting plate and the sawing tool are just started to process, but after the cutting plate and the sawing tool are used for a period of time, the cutting edges are worn and passivated, and saw marks, waves and even edge breakage can occur on the cutting end surface of the workpiece. Therefore, before the edge of the plate is sealed, the cut end face needs to be trimmed to reduce the phenomena of wave and edge breakage.

Usually, a disc-type milling cutter is adopted on edge banding equipment to trim the cut end faces of the plates, and the trimming effect of the disc-type milling cutter of the existing edge banding machine on the cut end faces of the plates is poor. This is because, when processing panels such as shaving board, multiply wood, ecological plate, because there is vertically and horizontally staggered's wood fiber, the radial cutting of cutter, wood fiber is difficult to cut off, and some places can produce the arch, and when the bag sealer banding, the banding strip can not wrap the panel completely, and the laminating is insecure, must rubber coating during the banding in addition, and glue spills over the face easily, can produce obvious glue line after the banding, influences pleasing to the eye.

SUMMERY OF THE UTILITY MODEL

Utility model purpose: the utility model aims at providing a to current panel for furniture board banding strip laminating insecure and the easy problem of appearing overflowing gluey when the banding, provide a produce the disk milling cutter that overflows gluey when being used for preventing the panel banding.

In order to achieve the above purpose, the utility model adopts the following technical scheme: the disc-type milling cutter comprises a cutter body and cutter teeth arranged on the outer circular surface of the cutter body, wherein the cutting outline of the cutter teeth is an arc.

Furthermore, the cutting profile of the cutter tooth is a symmetrical circular arc with a high middle and two low sides.

Further, the height difference between the highest point and the lowest point of the cutting profile of the cutter tooth is 0.02-0.5 mm.

Furthermore, the cutter teeth are split into a plurality of groups of cutting teeth along the direction of a rotating shaft of the cutter body, two adjacent groups of cutting teeth are mutually staggered in the circumferential direction and partially overlapped along the direction of the rotating shaft of the cutter body, the cutting profiles of each group of cutting teeth are short arcs, the cutting profiles of the two adjacent groups of cutting teeth have the same radius and are in smooth transition, and the cutting profiles of the cutting teeth of each group are spliced to form a smooth long arc.

Has the advantages that: utilize this circular arc cutting profile curve of disc milling cutter can produce slight arc surface on the work piece, and this arc surface can be in the glue containing space that panel and banding strip formed, can avoid panel to cut the terminal surface and have the fibre arch to cause the banding strip can not wrap up the panel completely, should hold gluey space and can hold appropriate amount of glue, make panel and banding strip fully adhere, and the banding strip is more firm with the laminating of panel, has avoided appearing the excessive phenomenon of gluing on the panel banding.

In the figure: 1, a cutter body; 1-1-outer circular surface; 1-2-rotation axis; 2-cutting teeth; 3-a plate material; 3-1-cutting end faces; 4-decorating edge banding strips; 5-glue containing space.

The specific implementation mode is as follows:

the present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 1, the disc milling cutter for preventing glue overflow during edge sealing of a plate of the present invention comprises a cutter body 1 and cutter teeth arranged on an outer circumferential surface 1-1 of the cutter body 1, wherein the cutting profile of the cutter teeth is a circular arc. The utility model discloses a cutting profile in indicates: during the rotation of the milling cutter, the cutting edge part of the cutter tooth forms the outer contour of the rotation surface.

In this embodiment, as shown in fig. 2 and 3, the cutting profile of the cutter tooth is a symmetrical arc with a high middle and two low sides, and the height difference T between the highest point and the lowest point of the cutting profile of the cutter tooth is controlled to be 0.02-0.5 mm according to the thickness of the plate 3, so that a fine concave arc surface can be processed on the cutting end surface 3-1 of the plate 3, and the adhesive can be conveniently applied in the process of attaching the decorative edge banding.

In order to reduce the resistance of the cutter teeth in the process of cutting a plate and reduce the abrasion, as shown in fig. 1 and 2, the cutter teeth are split into a plurality of groups of cutter teeth 2 along the direction of a rotating shaft 1-2 of a cutter body 1, two adjacent groups of cutter teeth 2 are staggered with a certain distance in the circumferential direction, the two adjacent groups of cutter teeth 2 are partially overlapped along the direction of the rotating shaft 1-2 of the cutter body 1, the overlapping size is D, the cutting profile of each group of cutter teeth 2 is a short circular arc, the cutting profiles of the two adjacent groups of cutter teeth 2 have the same radius and are in smooth transition, and the cutting profiles of the cutter teeth 2 are spliced to form a smooth long circular arc.

As shown in fig. 4 and 5, according to the method for preventing glue overflow when the edge of the plate material is sealed by the disc milling cutter, the height of the disc milling cutter is adjusted according to the thickness of the plate material 3, the highest point of the cutting profile of the cutter teeth is adjusted to be flush with the central position of the plate material 3, and then the cutting end surface 3-1 of the plate material 3 is processed into an arc surface by the cutter teeth with the arc-shaped cutting profile of the disc milling cutter, so that a glue containing space 5 is formed between the plate material 4 and the decorative edge sealing strip 4.

In the subsequent gluing and attaching process of the decorative edge banding 4, due to the existence of the glue containing space 5, the situation that the edge banding cannot completely wrap the panel due to the fact that the fiber protrusion exists on the cutting end face 3-1 of the panel can be avoided, the glue containing space 5 can contain a proper amount of glue, the panel 3 and the decorative edge banding 4 are fully bonded, the decorative edge banding 4 is more firmly attached to the panel 3, and meanwhile, the glue overflowing phenomenon of the attaching seam of the panel 3 and the decorative edge banding 4 is avoided.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
