[0002] The biggest advantages of plywood pallets are: export-ready without fumigation, free from insects and pests, and without time restrictions. They can be directly exported to Europe, America, and other countries worldwide. This product meets the import and environmental requirements of various countries, making it a great helper for export products. (Plywood belongs to the category of engineered wood products and is also called three-ply board). High-quality boards with a thickness of 12-18mm are used as pallet raw materials, making them sturdy and durable. In addition to producing products that meet the standards of various countries, pallets of various sizes can also be customized according to user needs. During the processing of plywood pallets, cutting and sanding operations are required, which necessitates the use of pallet edge cutting and sanding equipment.

[0003] However, current plywood pallet edge cutting and sanding devices on the market require the plywood pallet to be cut first, and then sanded by sanding equipment. This results in low cutting and sanding efficiency, increases processing steps, prolongs cutting and sanding time, and reduces the efficiency of the device. In addition, it is impossible to collect debris simultaneously during cutting and sanding, affecting the cleanliness of the device and polluting the processing environment, which is inconvenient for operators.

[0042] The base 1 has a support mounting assembly 5 at its bottom. The support mounting assembly 5 includes support rods 500 fixedly installed at the four corners of the bottom of the base 1. The bottom of the support rods 500 is threadedly connected to threaded legs 501. The bottom of the threaded legs 501 is rotatably connected to a support plate 502 through a bearing. The bottom of the support plate 502 is provided with anti-slip texture. The upper surface of the base 1 is provided with a groove. The inner bottom wall of the groove is inlaid with a rubber plate 6. The upper surface of the rubber plate 6 is provided with anti-slip texture. The rubber plate 6 facilitates the placement of the plywood pallet during use and prevents the pallet from slipping during use.

[0043] Working principle: During use, the equipment is initially leveled and its height is adjusted. The whole machine is placed in the processing area. The threaded support leg 501 of the rotating support mounting component 5 is rotated to drive the bottom support plate 502 to rise and fall. The anti-slip texture on the bottom of the support plate 502 completes the leveling and anti-slip fixation of the whole machine. Support rods 500 are set at the four corners of the bottom of the base 1 to ensure the stability of the equipment.

[0044] The plywood pallet to be processed is laid flat in the groove on the upper surface of the base 1. The groove is inlaid with a rubber plate 6, and the anti-slip texture on the surface of the rubber plate 6 prevents the plywood from slipping during processing.

[0045] Adjusting component 2 according to the thickness of the pallet plate: Loosen nut 203, and a through groove is opened on the side wall of positioning tube 200. Adjusting stud 202 can slide up and down along the through groove, driving positioning rod 201 to rise and fall to a suitable height. After the height is determined, tighten nut 203. Anti-slip ring 204 is clamped between nut 203 and positioning tube 200 to increase friction and lock positioning rod 201, avoiding height deviation during processing.

[0046] The processing angle can be freely adjusted. The top of the adjusting component 2 is fixed with a horizontal plate 300, which has a bearing embedded in it. A rotating rod 301 is inserted inside the bearing, allowing it to rotate 360°. A limiting ring 306 is provided above the bearing for limiting. The bottom of the bottom elastic support rod 307 of the baffle 302 is inlaid with a ball 308. The ball 308 rolls in contact with the top surface of the bearing, reducing rotational friction resistance. Rotating the rotating rod 301 can drive the lower housing 303 and the entire cutting and grinding component 4 to rotate, adapting to the processing of different corners of the pallet. A limiting rod 304 is fixed inside the housing 303. A torsion spring 305 is sleeved on the limiting rod 304. A cover plate 310 is sleeved on the threaded rod 309 at one end of the limiting rod 304. A threaded tightening ring 311 locks the cover plate 310, forming a limiting assembly for the torsion spring 305.

[0047] Downward pressing operation, simultaneous cutting, sanding, and dust extraction. The operator holds the handle of the cutting and polishing component 4 and pulls the pull rope 400 downwards to overcome the elasticity of the torsion spring 305, pressing the box 412 down to the edge of the tray. The concave strip 414 at the bottom of the box 412 contacts the board and squeezes the spring 410 in the internal mounting tube 409. After the spring 410 is compressed, it triggers the touch switch 411, and the entire circuit is turned on, and the drive motor 401 and the vacuum cleaner 407 start synchronously.

[0048] Power cutting and grinding process: The output shaft of the drive motor 401 drives the cutting rod 402 to rotate at high speed. The teeth 403 on the surface of the cutting rod 402 synchronously mesh with the gear 404 inside the box 412. The gear 404 drives the grinding rod 405 to rotate synchronously, and the grinding wheel 406 at the lower end of the grinding rod 405 rotates synchronously. The cutting rod 402 passes through the round hole at the bottom of the box 412 to complete the edge and corner cutting. The grinding wheel 406 passes through the through hole to synchronously polish the edge of the cut board. Two processes are completed in one press.

[0049] Synchronous dust removal process: The vacuum cleaner 407 works synchronously, and the airflow extends into the bottom processing area of ​​the box 412 through the air inlet pipe 408 to suck up the wood chips generated by cutting and sanding in real time. The vacuum cleaner 407 is equipped with a cleaning cover 413 on the outside. After the operation is completed, the cleaning cover 413 can be opened to discharge the collected dust and debris.

[0050] Release the pressure component, and the machine will automatically reset and stop. After the pallet edges are processed, the operator releases the handle of the cutting and polishing component 4. The torsion spring 305 inside the housing 303 releases its elastic tension, pulling the pull rope 400 upwards to retract, causing the box body 412 and drive motor 401 to be lifted as a whole, detaching from the surface of the board. After being lifted, the concave strip 414 separates from the board, the spring 410 rebounds, the touch switch 411 is turned off, and the drive motor 401 and vacuum cleaner 407 are simultaneously powered off. The equipment stops working and waits for the next processing.
