Description

Technical Field

[0001] The utility model relates to the technical field of edge banding machines, in particular to an edge banding machine and a flat shovel knife device thereof. Background Technique

[0002] An edge banding machine is a mechanical device specifically used in the woodworking and furniture manufacturing industries. It is mainly used for edge banding treatment of the edges of wood-based panels, artificial boards, metal plates and other materials to improve the aesthetics, durability and functionality of the panels. The edge banding process usually involves pasting an edge banding strip (such as PVC, ABS, wood grain paper, aluminum alloy, etc.) onto the edge of the panel, and then through processes such as grinding, trimming and polishing, the edge banding strip is tightly combined with the panel edge to form a flat and smooth edge surface.

[0003] During the edge banding work, after the panel and the rough trimming device have been roughly trimmed, the edge banding strip is broken into fragments and a small amount of powder by the diamond rough trimming knife. Due to the properties of the PVC edge banding strip, static electricity is generated, and there is residual glue on the edge banding strip, which often causes the broken edge banding strip to stick to the dust suction outlet, resulting in the blockage of the suction layer. If it is not cleaned in time after the blockage occurs, the subsequent panels will be contaminated with waste chips when passing through the diamond rough trimming knife, and there will be a blockage situation. Content of the Utility Model

[0004] Therefore, it is necessary to provide an edge banding machine and a flat shovel knife device thereof to solve the problems of static electricity generated due to the properties of the PVC edge banding strip, waste chips appearing after the panel passes through the diamond rough trimming knife, and blockage situations.

[0043] To describe in detail the technical content, structural features, achieved objectives and effects of the technical solution, the following will be described in detail in conjunction with specific embodiments and with reference to the accompanying drawings.

[0044] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , in this embodiment, a flat shovel knife device 15 of an edge banding machine is provided, which includes a limit plate 16, a first adjustment mechanism, an upper body 5, a linear motion mechanism 2, a second adjustment mechanism, a fixed seat 10, a blade 12 and a blowing mechanism. The limit plate 16 is connected to the upper body 5 through the first adjustment mechanism. The first adjustment mechanism is used to adjust the distance between the upper body 5 and the limit plate 16. A linear motion mechanism 2 is provided on the upper body 5. The linear motion mechanism 2 is connected to the lower body 6 and is used to translate the lower body 6 along a straight line. The lower body 6 is connected to the blade 12 through the second adjustment mechanism. The blade 12 is horizontally placed. A fixed seat 10 is provided on the lower body 6. A blowing hole 14 is provided on the fixed seat 10. The blowing mechanism is connected to the blowing hole 14 and is used to blow air into the blowing hole 14. The flat shovel knife device 15 further includes a linear guiding mechanism. The limit plate 16 is connected to the upper body 5 through the linear guiding mechanism, ensuring smooth sliding between the upper body 5 and the lower body 6 under the drive of the linear motion mechanism 2, and can improve the overall operation stability.

[0045] Pre-adjust the distance between the machine body and the plate through the fine adjustment of the first adjustment mechanism to avoid deformation or damage of the plate caused by excessive pressure. Pre-adjust the height of the blade 12 up and down through the second adjustment mechanism to control the cutting depth. When the edge banding machine is started, the linear motion mechanism 2 drives the lower body 6 to translate along the set path, driving the blade 12 to mill the plate, and the blowing mechanism blows air near the blade 12 through the blowing hole 14, blowing away the strip-shaped waste generated during the milling process, preventing blockage, keeping the working environment clean, and at the same time facilitating the recycling and treatment of the waste.

[0046] Please refer to Figure 2 , in this embodiment, the linear guiding mechanism includes two groups of sliding rods 4 and linear bearings 19 arranged side by side. There is one sliding rod 4 and one linear bearing 19 in one group. The two groups can be symmetric about the linear motion mechanism 2 left and right. The linear bearing 19 is provided in the upper body 5. The sliding rod 4 is slidably connected to the linear bearing 19. The sliding rod 4 is connected to the lower body 6. On the one hand, it ensures the stable connection between the limit plate 16 and the upper body 5. On the other hand, it provides accurate guidance for the machine body during linear motion, avoiding processing errors caused by deviation or shaking. One end of the sliding rod 4 can be fixed on the limit plate 16 through a sliding rod fixing nut 8, and the other end of the sliding rod 4 can be connected to a sliding rod locking nut 7 to form a more fixed connection.

[0047] Please refer to Figure 2, in this embodiment, the first adjustment mechanism includes a first stud 21 and a first nut 1. A first nut 1 is rotatably provided on the limit plate 16. The first nut 1 is threadedly connected to the first stud 21. The axial direction of the first stud 21 is along the direction from the upper body 5 to the lower body 6. The gap between the first stud 21 and the upper body 5 is an adjustable movement amount. When it is necessary to adjust the distance between the limit plate 16 and the upper body 5, the operator only needs to rotate the first nut 1. Due to the effect of the thread, the first stud 21 will move axially (up and down) relative to the first nut 1 to adjust the movement amount, playing a buffering role to prevent the plate member from being damaged.

[0048] Please refer to Figure 2 , in this embodiment, the second adjustment mechanism includes a second stud 20, a second nut 9 and a third nut 22. A second nut 9 and a third nut 22 are rotatably provided on the lower body 6. The second nut 9 and the third nut 22 are respectively threadedly connected to the second stud 20. The second stud 20 is connected to the blade 12. The axial direction of the second stud 20 is along the direction from the upper body 5 to the lower body 6. The blade 12 is located on the side of the lower body 6 away from the upper body 5. When it is necessary to adjust the position of the blade 12, the operator can independently rotate the second nut 9 or the third nut 22 to change the position of the second stud 20 relative to the lower body 6. Since the blade 12 is fixed to one end of the second stud 20, the up and down displacement of the second stud 20 also reflects the change in the up and down height of the blade 12.

[0049] Please refer to Figure 2 , in this embodiment, the linear motion mechanism 2 can be a component that can be telescoped in a straight line, such as an oil cylinder, a cylinder, or an electric push rod. Preferably, it is a cylinder. The cylinder block of the cylinder can be fixed to the upper body 5. In addition, a cylinder locking nut 17 can be used. The piston rod of the cylinder can be fixed to the upper body 5 through a fixing nut 18.

[0050] In this embodiment, the upper body 5 is fixed to the frame of the edge banding machine through 4 fixing holes 3 and 4 fasteners.

[0051] Please refer to Figure 2 , in this embodiment, the fixing seat 10 is provided with a limit groove adapted to the shape of the blade 12, and the blade 12 is provided in the limit groove to ensure that the blade 12 will not deflect too much during the working state.

[0052] Please refer to Figure 2 , in this embodiment, the blade 12 is an alloy flat shovel blade 12, usually made of high-strength and high-hardness materials such as high-speed steel and cemented carbide, and has excellent wear resistance and impact resistance.

[0053] Please refer to Figure 2, in this embodiment, the fixing base 10 protrudes from the lower edge of the lower body 6, and the lower corners of the fixing base 10 are rounded to enhance safety during operation and prevent damage to the plate due to impact.

[0054] In this embodiment, the air blowing mechanism includes an air blowing pump and an air blowing pipeline. The air blowing pump is connected to the air blowing holes 14 through the air blowing pipeline. The air blowing pump, as the source of air flow, can be driven by electricity or other power to generate an air flow with a certain pressure. The generated air flow is guided to the air blowing holes 14 on the fixing base 10 through the air blowing pipeline. When the blade 12 cuts, the waste generated will be blown away from the working area by the air flow released from the air blowing holes 14, avoiding the accumulation of waste and affecting the normal operation of the blade 12.

[0055] Please refer to Figure 2 , in this embodiment, the fixing base 10 can be fixed to the lower body 6 through the fixing base locking nut 11.

[0056] Please refer to Figure 2 , in this embodiment, the blade 12 can be fixed to the screw through the tool locking nut 13.

[0057] Please refer to Figures 1 to 4 , this embodiment further provides an edge banding machine, which includes a frame, a conveyor belt and a flat shovel knife device 15. A conveyor belt is provided on the frame, and the conveyor belt is used to convey the plate. The flat shovel knife device 15 is the flat shovel knife device 15 of an edge banding machine in any of the above embodiments. The limiting plate 16 of the flat shovel knife device 15 is arranged on the frame of the edge banding machine and is located on one side of the conveyor belt. The blade 12 of the flat shovel knife device 15 faces the direction of the conveyor belt and is used to contact the plate located on the conveyor belt. Among them, the air blowing pump of the flat shovel knife device 15 can be arranged on the frame.

[0058] The plate reaches the flat shovel knife device through the conveyor belt. The conveyor belt drives the plate to move. When passing through the flat shovel knife device, the lower body presses on the plate, and the blade and the plate surface are in a straight line to realize the action of milling the edge banding. The remaining material forms a roll during the milling process, and the air blowing port at the cutting edge blows air to blow the rolled edge banding out of the machine body.

[0059] It should be noted that the edge banding machine is an existing device. In this application, the flat shovel knife device 15 replaces the diamond roughing knife of the existing edge banding machine. It does not require the power of a motor, saves electric energy, can save two degrees of electricity per hour, and does not require dust collection. The waste passes through the flat shovel knife device and is discharged in strips, which is easy to recycle and can be reused.

[0060] Generally speaking, this application has the following beneficial effects:

[0061] 1. Using the flat shovel knife device, the waste passes through the flat shovel knife and is discharged in strips, which is easy to recycle and can be reused;

[0062] 2. Using a flat shovel device, the machine adjustment is simple, the method is fast, and the time consumption is short;

[0063] 3. The flat shovel device replaces the original rough repair. The original rough repair requires two motors with a power of 1KW to drive, consuming two degrees of electricity per hour.
