Description

Technical Field

[0001] The utility model relates to the technical field of plate trimming equipment, in particular to a tracking trimming device. 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

[0076] In some embodiments, the rotary drive mechanism 51 provides power to drive the tool 3. The plate is transported horizontally by a linear transport mechanism, such as a conveyor belt, to the tracking trimming device of one or more embodiments described herein, so that one of the upper surface, lower surface, front end face, and rear end face of the plate is aligned with the first guide cylindrical surface 1a of the first supporting roller 1, and the side face of the plate is aligned with the second guide annular surface 2a of the second supporting roller 2. The tool 3 rotates to chamfer one or more of the edges at the angle between the upper surface and the side face, the angle between the lower surface and the side face, the angle between the front end face and the side face, or the angle between the rear end face and the side face, or the four edges are chamfered in sequence.

[0077] In some embodiments, the linear drive mechanism 52 drives the second plate-like structure 54, the guide post 55, the first plate-like structure 51, and the second supporting wheel 2 to move toward or away from the tool 3. Based on the coverage of the tool 3 by the inner cylindrical surface of the second supporting wheel 2 and the pushing and positioning effect of the second guide annular surface 2a of the second supporting wheel 2 on the side of the plate, the feed depth of the plate relative to the tool 3 can be adjusted, thereby achieving different chamfering depths.

[0078] In one or more embodiments of the present specification, a tracking trimming method is also provided, which is suitable for a tracking trimming device. The tracking trimming method includes: driving the trimming mechanism B to move along with the movement of the plate, and making the tool 3 circle the outer edge of a surface to be trimmed of the plate while the trimming mechanism B moves along with the movement of the plate.

[0079] In one or more embodiments of the present specification, the tracking trimming method further includes: driving the second wheel 2 toward or away from the tool 3 to adjust the position of the plate, thereby adjusting the cutting position of the arc-shaped blade of the tool 3 relative to the edge of the plate.

[0080] In the above tracking trimming method, the first plane is a vertical plane. In other tracking trimming devices or tracking trimming methods not shown, the first plane may also be other planes close to the vertical plane, or a horizontal plane, or other planes close to the horizontal plane.

[0082] Taking a rectangular side of a plate as an example, it has an upper edge and a lower edge in the length direction, and a left edge and a right edge in the thickness direction. Based on the above-mentioned translational motion trajectory of the tool 3, the relative motion between the tool 3 and the plate can be achieved by transporting the plate in the first stage. Figures 1 to 3 As shown, the plate can move from the left side to the right side. In the first stage, the tool 3 cuts the upper edge of the plate. In the second stage, the tool 3 cuts the left edge of the plate. In the third stage, the tool 3 cuts the lower edge of the plate. In the fourth stage, the tool 3 cuts the right edge of the plate. In the fifth stage, the tool 3 resets and waits for the next plate.

[0083] In other embodiments, in the first stage, the tool 3 may also be in motion, as long as the speed difference between the tool 3 and the plate 3 is maintained. For example, see further Figures 1 to 3 As shown, during the movement of the plate 3 from left to right, the tool 3 may initially be located in the middle of the device and move to the left, thereby cutting the upper edge of the plate.

[0084] The translational motion trajectory of the tool 3 specifically refers to the running trajectory of the trimming mechanism B driven by the motion mechanism A. In addition to having the translational motion trajectory, the tool 3 also rotates during its translational motion trajectory to achieve cutting.

[0085] In the above-mentioned translation motion trajectory of the tool 3 , the first to fifth stages are not required to be implemented in sequence.

[0086] The above-mentioned translation motion trajectory of the tool 3 is not required to be implemented from the first stage, and it can also be implemented from any one of the first stage, the second stage, the third stage, and the fourth stage.

[0087] The above description is only a preferred embodiment of the present invention and does not limit the implementation method and protection scope of the present invention. For those skilled in the art, it should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
