Description

Technical Field

[0001] This invention relates to the field of edge banding machine technology, and specifically to an edge banding machine end-cutting mechanism with adjustable angle. Background Technology

[0002] In the manufacturing process of panel furniture, edge banding is a core process that determines the product's appearance quality, moisture resistance, and service life. The edge banding mechanism, as a key functional unit of the edge banding machine, is responsible for accurately removing excess edge banding strips that extend beyond the edge of the board at both ends.

[0003] Existing conventional edge banding and trimming mechanisms have the following significant drawbacks: The cutting mode is limited and cumbersome to adjust, only allowing for right-angle cuts. The resulting cuts produce sharp right-angle edges, affecting product aesthetics and posing a significant risk of injury to operators during handling and use. To achieve beveling, multiple sets of screws must be manually loosened, the saw blade angle adjusted, and the forward and backward positions repeatedly calibrated. This severely impacts production efficiency, and the adjustment accuracy is highly dependent on operator experience, making it difficult to guarantee consistency in mass production.

[0004] Without the function of pre-reserved edge banding, conventional edge-cutting mechanisms cut the edge banding flush with the end face of the board. In subsequent edge trimming processes, the cutting tool is very likely to damage the intact edge banding on the other side of the board. At the same time, due to uneven distribution of cutting force, it is easy to cause quality problems such as rough trimming surface, chipping, and warping.

[0005] Therefore, developing an edge banding machine end-cutting mechanism that can quickly switch cutting modes, reserve edge banding tape, achieve high cutting accuracy, and is easy to operate has become an urgent technical problem to be solved in this field. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide an edge banding machine end-cutting mechanism with adjustable angle, which can quickly switch between straight and oblique cutting modes without manual adjustment of screws, greatly shortening changeover time, providing good cutting effect, significantly improving safety, realizing the function of pre-reserving edge banding tape, reducing the scrap rate of subsequent processes, with stable structure and high adjustment accuracy.

[0007] To achieve the above objectives, the technical solution of the present invention is as follows: it is an angle-adjustable edge banding machine end-cutting mechanism, comprising: The conveying assembly, frame, and two inclined guide structures are provided on the frame; the two inclined supports are inclined downwards from left to right, with one inclined support located to the upper right of the other inclined support, the conveying assembly located on the left side of the lower left inclined support, and the two inclined guide structures respectively mounted on the corresponding inclined supports; and Two sway-angle cutting assemblies; the two sway-angle cutting assemblies are mounted on corresponding oblique guide structures.

Detailed Implementation

[0019] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding the present invention, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0020] like Figures 1 to 9 As shown, it is an angle-adjustable edge banding machine end-cutting mechanism, comprising: The conveying assembly 1, the frame 2, and two inclined guide structures 5 are provided on the frame 2. The two inclined supports 2a are inclined downwards from left to right, with one inclined support 2a located to the upper right of the other. The conveying assembly 1 is located on the left side of the lower left inclined support 2a. The two inclined guide structures 5 are respectively mounted on the corresponding inclined supports 2a. Two sway-angle cutting assemblies are provided. Each sway-angle cutting assembly is mounted on a corresponding oblique guide structure 5. Each assembly includes a first mounting base 3, a second mounting base 6, a motor displacement drive 7, a motor 8, a blade 10, a first mounting base drive 18, a third mounting base drive 19, a third mounting base 20, a second mounting base drive 21, and a fourth mounting base 22. The first mounting base 3 is mounted on the corresponding oblique guide structure 5 and moves with it. The first mounting base drive 18 is mounted on the frame 2, and its drive end is connected to the first mounting base 3, thereby driving the first mounting base 3 to move. The second mounting base 6 is mounted on the first mounting base 3 and can move back and forth on it. The second mounting base drive 21 is mounted on the first mounting base 3 and drives the second mounting base. The driving end of component 21 is connected to the second mounting base 6, thereby driving the second mounting base 6 to move. An arc-shaped guide structure 62 is provided on the second mounting base 6. The third mounting base 20 is mounted on the second mounting base 6 and cooperates with the arc-shaped guide structure 62 to rotate the third mounting base 20. The third mounting base driving component 19 is mounted on the second mounting base 6. The driving end of the third mounting base driving component 19 is connected to the third mounting base 20, thereby driving the third mounting base 20 to swing. The fourth mounting base 22 is mounted on the third mounting base 20 and can move left and right along the third mounting base 20. The motor displacement driving component 7 is mounted on the third mounting base 20. The driving end of the motor displacement driving component 7 is connected to the fourth mounting base 22, thereby driving the fourth mounting base 22 to move. The motor 8 is mounted on the fourth mounting base 22. The blade 10 is mounted on the output shaft of the motor 8.

[0021] During operation, the third mounting base drive 19, i.e., the swing cylinder, drives the third mounting base 20 to swing along the arc-shaped guide structure 62, which can quickly switch between straight cutting and bevel cutting modes without the need for manual adjustment of screws, greatly shortening changeover time and ensuring stable quality in mass production. In bevel cutting mode, the edges and corners of the board can be cut into a smooth 15° chamfer, completely eliminating the risk of sharp right-angle scratches and improving the product's aesthetics. The saw blade cutting position is precisely adjusted by the motor displacement drive 7, the first mounting base drive 18, the second mounting base drive 21, and the third mounting base drive 19, ensuring that excess edge banding can be accurately removed in both straight and bevel cutting modes, without incomplete or excessive cutting. It can also reserve edge banding, reducing the scrap rate in subsequent processes. It can reserve allowance at the end of the edge banding, effectively preventing the tool from damaging the edge banding on the other side of the board during subsequent trimming processes, while making the cutting force distribution more uniform. The multi-stage guide rail slide structure ensures smooth operation of all moving parts.

[0022] Straight cut mode: The third mounting base drive member 19 extends its drive end, causing the third mounting base 20 to swing along the arc-shaped guide structure 62, adjusting the motor 8 and the blade 10 to a vertical position; simultaneously, the second mounting base drive member 21 retracts its drive end, causing the second mounting base 6 to move backward to the rear limit position; subsequently, the first mounting base drive member 18 extends its drive end, driving the first mounting base 3 to move downward along the inclined guide structure 5, causing the blade 10 to approach the front end of the board; the motor 8 starts in advance, driving the blade 10 to rotate at high speed, and when the blade 10 contacts the edge banding, the excess edge banding at the front end of the board is removed; after cutting... The drive end of the first mounting base drive component 18 retracts, causing the sway angle cutting assembly to reset. The plate continues to be conveyed forward. When the rear end of the plate reaches the predetermined position, the drive end of the first mounting base drive component 18 extends, driving the first mounting base 3 to move downward along the inclined guide structure 5. The support wheel 91 mounted on the support frame 9 first adheres to the upper surface of the plate to play a guiding role. At the instant the support wheel 91 leaves the rear end of the workpiece, the motor displacement drive component 7 drives the blade 10 to feed quickly, cutting off the excess edge banding at the tail of the plate. After the cutting is completed, the upper sway angle cutting assembly resets, and the end trimming process ends.

[0023] Bevel mode: The third mounting base drive 19 retracts, causing the third mounting base 20 to swing along the arc-shaped guide structure 62, adjusting the motor 8 and the blade 10 to a 15° tilt position; at the same time, the second mounting base drive 21 extends, causing the second mounting base 6 to move forward to the front limit position; the subsequent cutting process is exactly the same as the straight cutting mode, and finally a 15° smooth chamfer is formed at the edge of the board, which is both beautiful and not easy to hurt hands.

[0024] Pre-reserved edge banding mode: The third mounting base drive 19 retracts, causing the third mounting base 20 to swing along the arc-shaped guide structure 62, adjusting the motor 8 and the blade 10 to a 15° tilt position; at the same time, the second mounting base drive 21 retracts, causing the second mounting base 6 to move back to the rear limit position; at this time, the cutting position of the saw blade is shifted backward relative to the bevel cutting mode, thus leaving a margin at the end of the edge banding; in the subsequent edge trimming process, the reserved edge banding can effectively protect the intact edge banding on the other side of the board from damage by the blade, while making the cutting force distribution more uniform and the trimming quality higher.

[0025] This invention achieves automatic switching between three working modes through a pneumatic system, eliminating the need for manual adjustment. It is easy to operate, has high production efficiency, and provides stable cutting quality, meeting the high precision and high efficiency requirements of modern panel furniture production.
