Description

Technical Field

[0001] The utility model relates to the technical field of plate trimming equipment, in particular to a trimming mechanism for the circumferential edge of a plate. Background Art

[0002] As people's living standards continue to improve, they pay more and more attention to the aesthetics and details of furniture. Therefore, some furniture manufacturers will perform edge banding on the edges of furniture when producing furniture (for example, attaching edge banding strips to the sides of the furniture edges). This can not only improve the appearance of the furniture, but also prevent sharp edges from causing cuts to the human body. After edge banding, it is usually necessary to further trim the edge banding strips to remove the part of the edge banding strips that protrude from the board, and further chamfer the board with the edge banding strips to obtain a rounded board shape.

[0003] Existing plate trimming mechanisms are typically designed with two sets of cutting tools, which can be arranged vertically or horizontally. The plate passes between the two sets of cutting tools (the gap between the two sets of cutting tools is equivalent to the thickness of the plate), thereby trimming and chamfering the edges between the two planes and the side surfaces of the plate. For example, when the two sets of cutting tools are arranged vertically, the plate is transported horizontally between the two sets of cutting tools, thereby chamfering the edges between the upper surface and the side surface, and between the lower surface and the side surface.

[0004] However, the aforementioned embodiment omitted the edges between the end face (i.e., the cross-section) and the side face of the sheet. Because the lengths of these two edges (the edge between the front face and the side face, and the edge between the rear face and the side face) are roughly the same as the thickness of the sheet, which is much smaller than both its length and width, conventional equipment cannot chamfer them. For example, if a trimming mechanism with two sets of cutting tools arranged one above the other were employed, the minimum gap between the two sets of tools would need to be equal to the width of the sheet. This makes tool gap errors difficult to control, easily leading to chamfering failures. Utility Model Content
