Description

Technical Field

[0001] This invention belongs to the field of particleboard production technology, and specifically discloses a processing equipment and method for producing particleboard based on recycled materials. Background Technology

[0002] Recycled wood particleboard is an environmentally friendly engineered wood product made from waste wood and wood processing residues through processes such as crushing, sorting, gluing, and hot pressing. The production of this type of board effectively realizes the recycling of wood resources, reducing production costs while alleviating the environmental pressure of waste wood. In the continuous production process of recycled wood particleboard, the formed raw boards need to be sawn to size according to downstream application requirements to obtain finished boards with uniform specifications. The sawing process, as the first finishing step after the board is formed, directly affects the effect of subsequent edge banding, surface finishing, and other processes, making it one of the key processes determining the final quality of the board.

[0003] Existing sawing equipment for recycled particleboard typically only uses an upper pressure beam or roller to apply unidirectional vertical pressure to the board during the sawing process. This lack of effective constraint on the separated portions of the board after sawing causes warping or displacement of these sections due to stress release at the moment of sawing completion, affecting the flatness of the cut surface. Furthermore, existing equipment generally lacks lateral limiting mechanisms, failing to effectively restrict the lateral freedom of the board. When the sawing position deviates from the center of the board or the board itself has slight warping deformation, the board is prone to lateral movement during sawing, causing dimensional deviations or even saw jamming. In addition, the large amount of debris generated during sawing accumulates on the worktable. Subsequent board transfer directly presses onto this debris, preventing the board from fully adhering to the worktable and creating localized gaps, severely affecting the flatness of the positioning reference surface and sawing accuracy.

[0011] Preferably, the lateral limiting mechanism includes two movable discs. A push block is provided at the middle of the upper end of each of the two movable discs. A second electric telescopic rod is provided on one side of each of the two push blocks. The two second electric telescopic rods are respectively fixed to one side of a corresponding inclined rod via a crossbar. A rotating roller is embedded in the lower part of one side of each movable disc. The rotating roller is used to contact the side of the material to achieve limiting. First ball bearings are embedded in the inner wall of each movable disc. The first ball bearings are used to make the movable disc slide smoothly on the outer wall of the first or second pressure roller. Second ball bearings are embedded in the lower end of each movable disc, and the lower ends of the multiple second ball bearings roll in contact with the upper part of the worktable.

[0012] A processing method for producing particleboard based on recycled materials includes the following steps: S1: The sheet material is conveyed to the worktable, and the lifting mechanism drives the first and second pressure rollers to descend synchronously and press the upper surface of the sheet material; at the same time, the lateral limiting mechanism is activated, and the second electric telescopic rod pushes the moving disc to move along the axial direction of the pressure rollers, so that the rotating rollers contact the two sides of the sheet material to achieve lateral limiting. S2: The hydraulic cylinder drives the saw blade to saw the board. The cutting grooves produced by the sawing fall into the collection frame and are discharged into the collection box. S3: After sawing is completed, the drive motor drives the first pressure roller to rotate 360°, and the material feeding pad pushes the cut and separated board to the guide plate; at the same time, the air intake mechanism circulates air into the pressure roller through the air intake pipe, and the air blowing nozzle blows away the debris on the workbench surface; the second pressure roller remains in a pressed state; after the material feeding and debris blowing are completed, the lifting mechanism drives the pressure roller to rise and reset, and the lateral limit mechanism retracts.

[0013] Compared with the prior art, the present invention has the following beneficial effects: By synchronously lifting and pressing the first and second pressure rollers, combined with the lateral limiting mechanism to roll and clamp the two sides of the board, the rolling limit on both sides of the board is achieved. This effectively suppresses the lateral movement of the board caused by warping or offset of the sawing position during the sawing process, and avoids damage to the loose fibers on the edge of the board through rolling contact, ensuring that the sawed surface is flat and the dimensions are accurate. After the sawing is completed, the first pressure roller rotates independently and uses the flexible contact between the silicone material feeding pad and the board to complete the material feeding. This avoids secondary damage to the edge and achieves smooth removal of the board after cutting, solving the common problems of concentrated force on the board and easy edge breakage during the feeding of existing equipment.

[0014] After sawing, while the first pressure roller rotates to push the material, the air intake mechanism drives the surface air nozzles through the internal air passage of the pressure roller to simultaneously clean the debris on the worktable, realizing the parallel operation of pushing and cleaning. The second pressure roller keeps the material pressed throughout the pushing process, providing stable support for the other side of the board and preventing displacement. The cutting groove material generated during the sawing process is collected in time by the collection frame and discharged into the collection box, completely eliminating the residue of debris on the worktable. This fundamentally solves the problem of debris raising causing inaccurate positioning of subsequent boards, significantly improving the stability of continuous processing and the yield rate.

Those skilled in the art can select appropriate models and perform conventional circuit design according to actual needs. Their specific working principles will not be elaborated here.

[0027] A processing method for producing particleboard based on recycled materials includes the following steps: S1: The sheet material is conveyed to the workbench 3. The lifting mechanism drives the first pressure roller 23 and the second pressure roller 24 to descend synchronously and press the upper surface of the sheet material. At the same time, the lateral limiting mechanism is activated, and the second electric telescopic rod 34 pushes the moving disc 36 to move along the pressure roller axis, so that the rotating roller 37 contacts the two sides of the sheet material to achieve lateral limiting. S2: The hydraulic cylinder 6 drives the saw blade 12 to saw the board. The cutting groove produced by the sawing falls into the collection frame 11 and is discharged into the collection box 15. S3: After sawing is completed, the drive motor 25 drives the first pressure roller 23 to rotate 360°, and the material feeding pad 40 pushes the cut and separated board to the guide plate 16; at the same time, the air intake mechanism circulates air into the pressure roller through the air intake pipe 28, and the air blowing nozzle 29 blows away the debris from the surface of the workbench 3; the second pressure roller 24 remains in a pressed state; after the material feeding and debris blowing are completed, the lifting mechanism drives the pressure roller to rise and reset, and the lateral limit mechanism retracts.

[0028] Working principle: During use, the recycled particleboard to be processed is automatically conveyed to the top of the workbench 3 through the material conveying mechanism. After it is in place, the lifting mechanism drives the first pressure roller 23 and the second pressure roller 24 to descend synchronously, pressing the upper surface of the board. At the same time, the lateral limiting mechanism is activated, and the second electric telescopic rod 34 pushes the moving disc 36 to move along the axis of the pressure roller, so that the rotating roller 37 rolls into contact with the two sides of the board, thereby achieving lateral limiting of the board and preventing lateral movement during the sawing process.

[0029] Subsequently, the hydraulic cylinder 6 drives the saw blade 12 to rise and pass through the cutting groove of the worktable 3 to saw the board. The material generated during the sawing process falls directly into the collection frame 11 and is discharged into the collection box 15 through the discharge port 13 for centralized collection.

[0030] After sawing is completed, the drive motor 25 drives the first pressure roller 23 to rotate 360° through the meshing of the drive gear 26 and the driven gear 27. The material-pushing pad 40 on the outer wall of the first pressure roller 23 contacts the cut and separated board and uses friction to push it to the guide plate 16. The board slides out along the guide plate 16 to complete the discharge. While the first pressure roller 23 rotates to push the material, the air intake mechanism introduces compressed air into the first pressure roller 23 and the second pressure roller 24 through the air intake pipe 28. The gas is sprayed out from the air blowing nozzle 29. The air blowing nozzle 29 on the surface of the first pressure roller 23 cleans the debris on the surface of the workbench 3, and the air blowing nozzle 29 inclined inside the second pressure roller 24 performs directional cleaning of the area near the saw blade 12. During the material pushing and chip blowing process, the second pressure roller 24 always remains in a pressed state to provide stable support for the board on the other side.

[0031] After the material feeding and chip blowing are completed, the lifting mechanism drives the first pressure roller 23 and the second pressure roller 24 to rise and reset synchronously, and the lateral limiting mechanism returns to the initial position to wait for the next cycle.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention.
