Description

Technical Field

[0001] The invention relates to processing equipment and a processing method for a plate required for producing plate-type furniture, in particular to a disc milling cutter and a method for preventing glue overflow when edge sealing a plate. Background Art

[0002] Currently, panel furniture is widely used. It is mainly made of particle board, density board, multi-layer board, ecological board, etc., with veneer on the surface. After cutting, the edges are refined and then coated with glue and then the edge strips are pasted.

[0003] Due to the different physical properties of the boards used in panel furniture, after cutting and sawing, the cut ends are uneven or have saw marks, waves, etc. If the edges are sealed directly, the edge banding strips will be difficult to fit, and obvious glue lines or glue overflow will occur.

[0004] Because the cutting and sawing tool edges are sharp, the workpiece surface processing quality is good at the beginning of processing due to the sharp cutting edge of the tool. However, after a period of use, the tool wears and the cutting edge becomes blunt, and saw marks, waves, and even edge collapse will appear on the cut end of the workpiece. Therefore, before the edge of the plate is sealed, the cut end needs to be trimmed to reduce the wave and edge collapse.

[0005] Disc milling cutters are usually used on edge banding equipment to trim the cut ends of boards. Existing disc milling cutters on edge banding machines have poor trimming effects on the cut ends of boards. This is because when processing particleboard, multilayer board, ecological board and other boards, the wood fibers are crisscrossed, and the radial cutting of the cutter makes it difficult to cut the wood fibers, and some places will produce bulges. When the edge banding machine is used for edge banding, the edge banding strip cannot completely wrap the board, and the fit is not secure. In addition, glue must be applied when edge banding, and the glue easily overflows from the board surface, resulting in obvious glue lines after edge banding, affecting the appearance. Summary of the invention

[0006] Purpose of the invention: The purpose of the present invention is to provide a disc milling cutter and method for preventing glue overflow when edge sealing the panels, in order to solve the problem that the edge banding strips of the panels used in existing panel furniture are not firmly attached and glue overflow is easy to occur when edge sealing the panels.

[0007] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: a disc milling cutter for preventing glue overflow during edge sealing of a plate, comprising a cutter body and teeth arranged on the outer circumferential surface of the cutter body, wherein the cutting profile of the teeth is an arc.

[0008] Furthermore, the cutting profile of the blade teeth is a symmetrical arc that is high in the middle and low on both sides.

[0009] Furthermore, the height difference between the highest point and the lowest point of the cutting profile of the blade teeth is 0.02-0.5 mm.

[0010] Furthermore, the cutting teeth are divided into several groups of cutting teeth along the rotating axis direction of the blade body. Two adjacent groups of cutting teeth are staggered in the circumferential direction and partially overlap along the rotating axis direction of the blade body. The cutting profile of each group of cutting teeth is a short arc. The radius of the cutting profile of two adjacent groups of cutting teeth is the same and the transition is smooth. The cutting profiles of each group of cutting teeth are spliced ​​together to form a smooth long arc.

[0011] According to the method for preventing glue overflow when edge banding a plate using the above-mentioned disc milling cutter: the height of the disc milling cutter is adjusted according to the thickness of the plate, and the cut end surface of the plate is processed into an arc surface using the teeth of the disc milling cutter having an arc-shaped cutting profile, thereby forming a glue-containing space between the plate and the decorative edge banding strip.

[0012] Beneficial effect: The circular cutting contour curve of the disc milling cutter can produce a subtle arc surface on the workpiece. This arc surface can form a glue-containing space between the plate and the edge banding strip, which can avoid the presence of fiber protrusions on the cut end face of the plate, resulting in the edge banding strip being unable to completely wrap the plate. The glue-containing space can accommodate an appropriate amount of glue, so that the plate and the edge banding strip are fully bonded, the edge banding strip and the plate fit more firmly, and glue overflow on the edge banding of the plate is avoided.

[0019] The present invention will be further explained below in conjunction with the accompanying drawings.

[0020] like Figure 1As shown, a disc milling cutter for preventing glue overflow during edge sealing of a plate according to 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 an arc. The cutting profile in the present invention refers to the outer profile of the rotating surface formed by the cutting edge of the cutter teeth during the rotation of the milling cutter.

[0021] In this embodiment, Figure 2 and 3 As shown, the cutting profile of the blade teeth is a symmetrical arc that is high in the middle and low on both sides. According to the thickness of the plate 3, the height difference T between the highest point and the lowest point of the cutting profile of the blade teeth is controlled at 0.02-0.5 mm. In this way, a fine concave arc surface can be processed on the cutting end surface 3-1 of the plate 3, which is convenient for gluing during the bonding process of the decorative edge banding.

[0022] In order to reduce the resistance of the blade when cutting the plate and reduce wear, Figure 1 and 2 As shown, the cutter teeth are divided into several groups of cutting teeth 2 along the rotating axis 1-2 direction of the cutter body 1, and two adjacent groups of cutting teeth 2 are staggered at a certain distance in the circumferential direction, and two adjacent groups of cutting teeth 2 partially overlap along the rotating axis 1-2 direction of the cutter body 1, and the overlap size is D. The cutting profile of each group of cutting teeth 2 is a short arc, and the radius of the cutting profile of two adjacent groups of cutting teeth 2 is the same and the transition is smooth. The cutting profiles of each group of cutting teeth 2 are spliced ​​together to form a smooth long arc.

[0023] like Figure 4 and 5 As shown, according to the method for preventing glue overflow during edge banding of a plate using the above-mentioned disc milling cutter, the method is to adjust the height of the disc milling cutter according to the thickness of the plate 3, adjust the highest point of the cutting profile of the cutter teeth to be flush with the center position of the plate 3, and then use the cutter teeth of the disc milling cutter with an arc-shaped cutting profile to process the cutting end surface 3-1 of the plate 3 into an arc surface, thereby forming a glue-containing space 5 between the plate 4 and the decorative edge banding strip 4.

[0024] In the subsequent process of gluing and bonding the decorative edge banding strip 4, the existence of the glue holding space 5 can avoid the fiber protrusions on the cut end surface 3-1 of the board 3, which may cause the edge banding strip to be unable to completely wrap the board. The glue holding space 5 can accommodate an appropriate amount of glue to fully bond the board 3 and the decorative edge banding strip 4, so that the decorative edge banding strip 4 and the board 3 are more firmly bonded, and at the same time, glue overflow in the bonding seam between the board 3 and the decorative edge banding strip 4 is avoided.

[0025] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
