Description

Technical Field

[0001] This utility model relates to the technical field of particleboard production equipment, specifically to a trimming and cutting device for particleboard production. Background Technology

[0002] Side trimming of particleboard is a crucial step in the production process to ensure accurate product dimensions and neat edges, involving multiple stages and technological steps. First, after inspection and pre-treatment, the raw materials are placed on a conveyor system and enter the trimming stage. Commonly used trimming equipment includes CNC panel saws or high-speed cutting saws, which can automatically trim according to preset dimensional parameters. Operators set the trimming dimensions, speed, and pressure via a control panel, ensuring the board is precisely positioned and clamped before trimming to prevent movement and guarantee straight lines and accuracy. During the trimming process, the saw blade or cutter gradually trims the board edges along a predetermined path, using multiple cuts to progressively achieve the design requirements. After cutting, minor unevenness or burrs may remain on the edges. Therefore, sanding and scraping processes are performed to ensure smooth and neat edges. However, current side-cutting equipment, using a high-speed cutting saw, can only complete the cutting of the left or right side in a single processing operation. This means the cutting path is limited by the guide rails, clamping devices, and the range of motion of the cutting tool. The equipment needs to be adjusted or repositioned after cutting one side before cutting the other side. Because only one side can be cut at a time, the entire cutting process becomes cumbersome and time-consuming. Especially in mass production, multiple cutting steps significantly reduce production efficiency. Furthermore, the need for mechanical adjustment and repositioning after each cut can lead to accumulated errors, affecting the dimensional consistency of the final product. Utility Model Content

[0003] The purpose of this invention is to provide a trimming and cutting device for particleboard production. The particleboard to be trimmed simultaneously on both sides is placed at the bottom of a U-shaped hollow frame. After adjusting the position of the particleboard and the left cutting disc, the position of the L-shaped shaft carrier, T-shaped hollow bushing, inner spline shaft, and right cutting disc is controlled by the control panel and the X-axis lead screw electric module. After adjustment, the motor transmits power to the outer spline shaft and the inner spline shaft, causing the left and right cutting discs to rotate synchronously. The operator manually pushes the particleboard until the left and right cutting discs complete the trimming of the particleboard, thus solving the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a trimming and cutting device for particleboard production, comprising a U-shaped bottom hollow frame, sponge rollers rotatably mounted at the front and rear positions inside the U-shaped bottom hollow frame via bearing seats, a drive shaft rotatably mounted on one inner wall of the U-shaped bottom hollow frame, and an external spline shaft rotatably mounted on the inner wall of the U-shaped bottom hollow frame below the drive shaft. A left cutting disc is fixed to one end of the external spline shaft near the inner wall of the U-shaped bottom hollow frame. A three-gear speed-increasing transmission structure is installed between the drive shaft and the external spline shaft. A three-chain drive structure for power transmission is installed between the two sponge rollers and the drive shaft. A motor for driving one of the sponge rollers to rotate is installed on one side of the outer wall of the frame. An X-axis lead screw electric module is installed on the other side of the inner wall of the U-shaped bottom hollow frame. An L-shaped shaft carrier is fixed to the moving end of the X-axis lead screw electric module. A T-shaped hollow bushing is fixed inside the L-shaped shaft carrier. An inner spline shaft is rotatably installed inside the T-shaped hollow bushing. The inner spline shaft and the outer spline shaft are concentrically fitted. A right cutting disc is fixed to the end of the inner spline shaft away from the outer spline shaft. A control panel is installed on the outer wall of the U-shaped bottom hollow frame on the side of the motor. The output end of the control panel is electrically connected to the input end of the X-axis lead screw electric module and the motor.

[0005] Preferably, pads are installed at the corners of the bottom of the U-shaped hollow frame.

[0006] Preferably, the three-sprocket drive structure includes a first sprocket mounted on the same end of two sponge rollers and a second sprocket fixed on one end of the drive shaft. Chains are mounted on the two first sprockets and the second sprocket, and the diameter of the first sprocket is smaller than the diameter of the second sprocket.

[0007] Preferably, square crossbeams are fixed at both the front and rear positions inside the U-shaped hollow frame, and the square crossbeams are located above the sponge roller.

[0008] Preferably, the length of the internal spline shaft is 1.5m to 2m.

[0009] Preferably, the inner wall of the T-shaped hollow bushing is provided with two annular grooves, and one end of the surface of the inner spline shaft is fixed with an annular flange for engaging with the annular grooves.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This edge trimming equipment for particleboard production has a structure that includes a U-shaped bottom hollow frame, an outer spline rotating shaft, a left cutting disc, an X-axis lead screw electric module, an L-shaped shaft carrier, and an inner spline rotating shaft. The particleboard to be trimmed simultaneously on both sides is placed at the bottom of the U-shaped bottom hollow frame. After adjusting the position of the particleboard and the left cutting disc, the position of the L-shaped shaft carrier, the T-shaped hollow bushing, the inner spline rotating shaft, and the right cutting disc are controlled by the control panel and the X-axis lead screw electric module. After the adjustment is completed, the motor transmits power to the outer spline rotating shaft and the inner spline rotating shaft, causing the left and right cutting discs to rotate synchronously. The operator manually pushes the particleboard until the left and right cutting discs complete the edge trimming of the particleboard.

[0011] The system employs a well-designed mechanical structure, placing the particleboard at the bottom of a U-shaped, perforated frame to ensure stability and prevent positional shifts during cutting. After adjusting the position of the particleboard relative to the left cutting disc, the control panel and X-axis lead screw motor precisely control the relative positions of the left and right cutting discs, achieving accurate edge positioning. This ensures the cut edges not only conform to design dimensions but also maintain symmetry, significantly improving product appearance and structural precision. Furthermore, the internal spline shaft and synchronized rotation of the left and right cutting discs ensure synchronized movement throughout the cutting process, preventing uneven edges or dimensional errors caused by asynchrony. Synchronized rotation not only guarantees smooth cut edges but also effectively reduces material waste and rework due to deviations, improving overall production efficiency. Finally, operators simply push the particleboard manually, coordinating with the synchronized mechanical control, to achieve fast and accurate edge cutting. This semi-automated operation, combined with precise mechanical control, reduces operational difficulty and shortens cutting time, meeting the demands of high-efficiency production.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0020] Please see Figure 1-6 This utility model provides an embodiment of a particleboard trimming device, comprising a U-shaped bottom hollow frame 1, sponge rollers 2 rotatably mounted at the front and rear positions inside the U-shaped bottom hollow frame 1 via bearing seats, a drive shaft 3 rotatably mounted on one side of the inner wall of the U-shaped bottom hollow frame 1, and an external spline shaft 5 rotatably mounted on the inner wall of the U-shaped bottom hollow frame 1 below the drive shaft 3. A left cutting disc 6 is fixed to one end of the external spline shaft 5 near the inner wall of the U-shaped bottom hollow frame 1. A three-gear speed-increasing transmission structure 7 is installed between the drive shaft 3 and the external spline shaft 5. Two sponge rollers 2 are installed between the two sponge rollers 2 and the drive shaft 3. There is a three-chain drive structure 4 for power transmission. A motor 13 for driving one of the sponge rollers 2 to rotate is installed on one outer wall of the U-shaped bottom hollow frame 1. An X-axis lead screw electric module 8 is installed on the inner wall of the other side of the U-shaped bottom hollow frame 1. An L-shaped axle carrier 9 is fixed at the moving end of the X-axis lead screw electric module 8. A T-shaped hollow bushing 901 is fixed inside the L-shaped axle carrier 9. An inner spline shaft 10 is rotatably installed inside the T-shaped hollow bushing 901. The inner spline shaft 10 and the outer spline shaft 5 are concentrically fitted. The length of the inner spline shaft 10 is 1.5m to 2m.

[0021] A right cutting disc 11 is fixed at the end of the inner spline shaft 10 away from the outer spline shaft 5. A control panel 12 is installed on the outer wall of the U-shaped bottom hollow frame 1 on one side of the motor 13. The output end of the control panel 12 is electrically connected to the input end of the X-axis lead screw electric module 8 and the motor 13.

[0022] The U-shaped bottom hollow frame 1 provides a sturdy and stable working platform, effectively preventing vibration and shifting, and ensuring the stability of the particleboard and the accuracy of the cutting process;

[0023] A pad 101 is installed at the corner of the bottom of the U-shaped hollow frame 1. The pad 101 can be processed into different thicknesses. By selecting a pad 101 with a suitable thickness, the pad 101 can lift the particleboard upwards, so that the upper surface of the particleboard contacts the sponge roller 2.

[0024] The three-sprocket drive structure 4 includes a first sprocket mounted on the same end of two sponge rollers 2 and a second sprocket fixed on one end of the drive shaft 3. Chains are mounted on the first and second sprockets. The diameter of the first sprocket is smaller than that of the second sprocket. When the motor 13 drives one of the sponge rollers 2 to rotate, the other sponge roller 2 also rotates synchronously under the drive of the three-sprocket drive structure 4, and then actively sweeps out the debris attached to the particleboard through the sponge roller 2.

[0025] The sponge roller 2 drives the drive shaft 3 to rotate through the three-chain drive structure 4. Then, the drive shaft 3 forces the external spline shaft 5 to rotate through the three-gear speed-increasing drive structure 7, so that the sponge roller 2, drive shaft 3, external spline shaft 5, and right cutting disc 11 share the rotational power from the motor 13.

[0026] Square crossbeams are fixed at the front and rear positions inside the U-shaped bottom hollow frame 1, and the square crossbeams are located above the sponge roller 2.

[0027] The X-axis ball screw electric module 8 provides high-precision, controllable linear motion, which can easily and quickly fine-tune the cutting position of the right cutting disc 11 to ensure the accuracy of the cutting path.

[0028] The inner wall of the T-shaped hollow bushing 901 is provided with two annular grooves. One end of the surface of the inner spline shaft 10 is fixed with an annular flange for engaging with the annular grooves. The two annular grooves on the inner wall of the T-shaped hollow bushing 901 and the two annular flanges on the outer wall of the inner spline shaft 10 engage with each other, thereby supporting the rotation of the inner spline shaft 10 through the T-shaped hollow bushing 901. When the outer spline shaft 5 stops rotating, the inner spline shaft 10 and the right cutting disk 11 can be driven to move laterally linearly through the X-axis lead screw electric module 8, the L-shaped shaft carrier 9, and the T-shaped hollow bushing 901.

[0029] In this embodiment, the worker first places the particleboard to be cut at the bottom of the U-shaped hollow frame 1, ensuring the particleboard is stable and flat. Then, the position of the particleboard and the left cutting disc 6 is fine-tuned. After the position is adjusted, the worker controls the X-axis lead screw electric module 8 via the control panel 12. The X-axis lead screw electric module 8 drives the L-shaped shaft carrier 9, the T-shaped hollow bushing 901, the internal spline shaft 10, and the right cutting disc 11 to move left and right, precisely adjusting the position of the right cutting disc 11 according to the particleboard's dimensions. This ensures that the left and right cutting discs 6 and 11 can cut edges that meet specifications along a predetermined trajectory, achieving a consistent cutting distance between the right and left cutting discs 11. After the position adjustment is complete, the worker... The operator restarts the motor 13 via the control panel 12. The motor 13 first drives one of the sponge rollers 2 to rotate. Then, the sponge roller 2 transmits the rotational power to the outer spline shaft 5 through the three-chain drive structure 4, drive shaft 3, and three-gear speed-increasing drive structure 7. The outer spline shaft 5 drives the left cutting disc 6, the inner spline shaft 10, and the right cutting disc 11 to rotate synchronously. After the left cutting disc 6 and the right cutting disc 11 have rotated, the operator manually pushes the particleboard, causing it to gradually enter the cutting area along the predetermined path. That is, the left cutting disc 6 and the right cutting disc 11 simultaneously cut both sides of the particleboard. The operator should maintain a uniform and stable pushing force to avoid affecting the cutting effect due to human deviation. After the cutting is completed, the operator gradually removes the particleboard and checks whether the flatness and size of the cut edges meet the requirements.
