Description

Technical Field

[0001] This utility model relates to the field of furniture processing technology, specifically to a planer device for furniture processing. Background Technology

[0002] The planer is a core piece of equipment in furniture making used to plan and polish the surface and edges of wood. It cuts the surface of the wood with planing blades to achieve a flat and square effect, providing a precise reference surface for subsequent processing.

[0003] In existing planing devices, a safety push handle is typically used to press against the surface of the wood to assist in manual feeding. When the wood contains knots, has disordered fiber grain, or is unusually hard, the resistance generated when the planer blade contacts the wood suddenly increases, causing the wood to bounce uncontrollably or unexpectedly rebound under the planing force, which can injure the operator. Therefore, a planing device for furniture processing is proposed to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a planer for furniture processing, which has the advantage of high safety. It solves the problem that in existing planer devices, the planer pushes the wood by pressing a safety handle against the surface of the wood to assist in manual feeding. When the wood contains knots, has disordered fiber texture, or is abnormally hard, the resistance generated when the planer blade contacts the wood suddenly increases, which can easily cause jumping or rebounding, thus causing injury to the operator.

[0005] To achieve the aforementioned goal of high safety in use, this utility model provides the following technical solution: a planer for furniture processing, comprising a planer table, wherein a planing mechanism is provided on the planer table; and a board limiting mechanism is provided on the surface of the planer table; The plate limiting mechanism includes two mounting side plates fixedly installed on the upper surface of the flat polishing platform. An electric push rod is fixedly installed on the surface of the mounting side plate. A mounting box is fixedly installed at the output end of the electric push rod. A feeding drive assembly is provided inside the mounting box. A mounting frame is fixedly installed on the top of the mounting side plate. A cylinder with its output end extending through the inner side of the mounting frame is fixedly installed on the upper surface of the mounting frame. A U-shaped frame is fixedly installed at the output end of the cylinder. A pressure roller is rotatably installed inside the U-shaped frame.

[0006] Furthermore, each of the mounting side plate surfaces has four electric push rods, each of the mounting side plate surfaces has two mounting boxes, and there are two electric push rods between the mounting boxes and the mounting side plate.

[0007] Furthermore, the feeding drive assembly includes two drive rollers rotatably mounted inside the mounting box, a plurality of clamping rollers rotatably mounted on the surface of the mounting box away from the electric push rod, a conveyor belt sleeved on the surface of the drive rollers and sleeved with the clamping rollers, and two drive motors fixedly mounted on the top surface of the mounting box, the output end of the drive motors extending into the mounting box and fixedly connected to the drive rollers.

[0008] Furthermore, a rectangular hole is provided on the surface of the mounting box away from the electric push rod, the pressure roller is rotatably mounted inside the rectangular hole and the pressure roller part protrudes out of the rectangular hole, and the conveyor belt extends to the outer surface of the mounting box through the rectangular hole.

[0009] Furthermore, the number of cylinders is three, and the three cylinders are arranged in a straight line on the upper surface of the mounting frame. The number of U-shaped frames and pressure rollers is the same as the number of cylinders.

[0010] Furthermore, the planing mechanism includes a fixed plate fixedly installed on the opposite side surface of the planer table, a planing blade fixedly installed between the opposite sides of the two fixed plates, a planing motor fixedly installed on the surface of one of the fixed plates, the output end of the planing motor passing through the fixed plate and fixedly connected to the planing blade, and a strip hole opened on the surface of the planer table.

[0011] Furthermore, the outer shape of the polishing cutter is cylindrical, the polishing cutter is located inside the strip-shaped hole, the inner width of the strip-shaped hole is greater than the diameter of the polishing cutter, the inner length of the strip-shaped hole is greater than the length of the polishing cutter, and the highest point of the polishing cutter is higher than the surface of the planer table.

[0012] Furthermore, each pair of the mounting boxes is distributed as a group on both sides of the blasting blade and the strip hole.

[0013] Furthermore, the surface of the pressure roller is provided with a groove, and the inner surface of the groove is arc-shaped.

[0014] Compared with the prior art, this utility model provides a planer device for furniture processing, which has the following beneficial effects: 1. This planer for furniture processing uses a cylinder-driven U-shaped frame to press down pressure rollers, firmly pressing the wood onto the planer table. This effectively limits the wood's movement and rebound during processing. A drive motor rotates the drive rollers, which in turn drive the conveyor belt, achieving automatic feeding of the wood. Simultaneously, the pressure rollers, in conjunction with the conveyor belt, further clamp and limit the wood laterally, ensuring stability during feeding. This significantly reduces the risk of operator injury and avoids processing quality problems caused by unstable manual feeding, improving the precision and consistency of furniture processing.

[0015] 2. The planer for furniture processing has an inner arc-shaped groove on the surface of the pressure roller, which allows the pressure roller to adapt to both flat and arc-shaped wood surfaces, thus improving the adaptability of the pressure roller. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-5This embodiment of a planer for furniture processing includes a planer table 1, on which a planing mechanism 2 is provided; a board limiting mechanism 3 is provided on the surface of the planer table 1, the board limiting mechanism 3 includes two mounting side plates 31 fixedly installed on the upper surface of the planing table 1, an electric push rod 32 is fixedly installed on the surface of the mounting side plate 31, a mounting box 33 is fixedly installed at the output end of the electric push rod 32, a feeding drive assembly 34 is provided inside the mounting box 33, a mounting frame 35 is fixedly installed on the top of the mounting side plate 31, a cylinder 36 with its output end penetrating to the inside of the mounting frame 35 is fixedly installed on the upper surface of the mounting frame 35, a U-shaped frame 37 is fixedly installed at the output end of the cylinder 36, and a pressure roller 38 is rotatably installed inside the U-shaped frame 37. By setting the board limiting mechanism 3, the board can be limited and fixed, and the board can be prevented from jumping and rebounding during processing.

[0020] In this embodiment, there are four electric push rods 32 on each mounting side plate 31 surface, two mounting boxes 33 on each mounting side plate 31 surface, and two electric push rods 32 between the mounting box 33 and the mounting side plate 31. The lower surface of the mounting box 33 slides in contact with the upper surface of the planer table 1, so that the electric push rods 32 can smoothly adjust the position of the mounting box 33.

[0021] In this embodiment, the feeding drive assembly 34 includes two drive rollers 341 rotatably mounted inside the mounting box 33. A plurality of pressing rollers 342 are rotatably mounted on the surface of the mounting box 33 away from the electric push rod 32. A conveyor belt 343 is sleeved on the surface of the drive rollers 341 and sleeved with the pressing rollers 342. Two drive motors 344 are fixedly mounted on the top surface of the mounting box 33. The output end of the drive motors 344 extends into the mounting box 33 and is fixedly connected to the drive rollers 341. By setting the feeding drive assembly 34, the automatic conveying of the board material can be realized, which can avoid the safety hazards caused by manual conveying of the board material.

[0022] In this embodiment, a rectangular hole 5 is provided on the surface of the mounting box 33 away from the electric push rod 32. The pressure roller 342 is rotatably mounted inside the rectangular hole 5 and part of the pressure roller 342 protrudes out of the rectangular hole 5. The conveyor belt 343 extends to the outer surface of the mounting box 33 through the rectangular hole 5.

[0023] In this embodiment, there are three cylinders 36, which are arranged in a straight line on the upper surface of the mounting frame 35. The number of U-shaped frames 37 and pressure rollers 38 is the same as the number of cylinders 36. The pressing effect on the plate can be improved by using three cylinders 36 and pressure rollers 38.

[0024] In this embodiment, the planing mechanism 2 includes a fixed plate 21 fixedly installed on the opposite side surface of the planer table 1. A planing blade 22 is fixedly installed between the opposite sides of the two fixed plates 21. A planing motor 23 is fixedly installed on the surface of one of the fixed plates 21. The output end of the planing motor 23 passes through the fixed plate 21 and is fixedly connected to the planing blade 22. A strip hole 24 is opened on the surface of the planer table 1.

[0025] In this embodiment, the outer shape of the polishing cutter 22 is cylindrical. The polishing cutter 22 is located inside the strip hole 24. The inner width of the strip hole 24 is greater than the diameter of the polishing cutter 22, and the inner length of the strip hole 24 is greater than the length of the polishing cutter 22. The highest point of the polishing cutter 22 is higher than the surface of the planer table 1.

[0026] In this embodiment, every two mounting boxes 33 are distributed as a group on both sides of the polishing blade 22 and the strip hole 24.

[0027] In this embodiment, the surface of the pressure roller 38 is provided with a groove 4, and the inner surface of the groove 4 is arc-shaped, so that the pressure roller 38 can adapt to different shaped plates, which is beneficial to improving the adaptability of the pressure roller 38.

[0028] It should be noted that the multiple electric push rods 32 in this embodiment are precisely controlled by a programmable logic controller. The synchronous movement of the multiple electric push rods 32 is achieved through programming, so that the mounting boxes 33 on both sides can be adjusted to the same distance synchronously, and the planer 1 holding the plate is positioned in the middle.

[0029] The working principle of the above embodiments is as follows: The operator places the board to be processed on the planer table 1, positioning the wood between the opposing surfaces of the two mounting boxes 33. The position of the mounting boxes 33 is adjusted using the electric push rod 32, causing the conveyor belt 343 to contact the side surface of the wood, thus providing lateral clamping and limiting of the wood. The cylinder 36 is activated, its output end extending downwards, pushing the fixedly connected U-shaped frame 37 downwards until the pressure roller 38 presses against the upper surface of the board, thus securely fixing the board to the planer table 1. Simultaneously, the two drive motors 344 are activated. 4. The output end drives two drive rollers 341 to rotate. The rotation of the drive rollers 341 drives the conveyor belt 343 to move. At the same time, the pressure roller 342 can support the conveyor belt 343, so that the conveyor belt 343 is in close contact with the side surface of the plate, ensuring that the plate can move forward smoothly with the movement of the conveyor belt 343, realizing automatic feeding. The flat polishing motor 23 starts and drives the polishing knife 22 to rotate at high speed. When the plate passes above the strip hole 24, the high-speed rotating polishing knife 22 performs planing processing on the lower surface of the plate, processing the plate to the required thickness and flatness.
