Description

Technical Field

[0001] This utility model belongs to the field of multi-layer board pallet processing technology, specifically relating to a dust removal device for multi-layer board pallet processing. Background Technology

[0002] Multi-layer plywood pallets (also known as composite board pallets or plywood pallets) are pallets made primarily from multi-layer plywood and are widely used in logistics transportation, warehousing and cargo containerization. Compared to traditional solid wood pallets, they feature high strength, good stability, no fumigation required (meeting international export standards), and high cost-effectiveness, making them particularly suitable for cross-border trade and scenarios with high pallet performance requirements.

[0003] Specifically, during the cutting of plywood pallets, the high-speed saw blade violently rubs against the multi-layer plywood (made of veneers such as poplar and pine), generating a large amount of sawdust and dust of varying sizes—including visible wood chips and many fine particles smaller than 10μm in diameter. These pollutants drift uncontrollably around the workshop, not only adhering to precision components of the processing equipment (such as saw blade bearings and transmission gears) and work surfaces, leading to increased equipment wear, decreased precision, and increased maintenance costs; but also permeating the working environment. If inhaled by workers, long-term accumulation can lead to occupational diseases such as pneumoconiosis and bronchitis, endangering their health. Utility Model Content

[0004] The purpose of this invention is to provide a dust removal device for processing multi-layer plywood pallets. This device addresses the problem that during the cutting process of multi-layer plywood pallets, the high-speed rotating saw blade and the multi-layer plywood (made of veneers such as poplar and pine bonded together) generate a large amount of sawdust and dust of varying particle sizes—including visible wood chips and many fine particles with a diameter of less than 10μm. These pollutants drift uncontrollably around the workshop, adhering not only to precision components of the processing equipment (such as saw blade bearings and transmission gears) and the work surface, leading to increased equipment wear, decreased precision, and increased maintenance costs, but also permeating the working environment. If inhaled by workers, long-term accumulation can lead to occupational diseases such as pneumoconiosis and bronchitis, endangering their health.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dust removal device for processing multi-layer board pallets, including a pallet cutting table and a dust collection hood installed on the bottom surface of the pallet cutting table. A steel pipe is connected to the bottom end of the dust collection hood, a fan is connected to the other end of the steel pipe, and a dust collection pipe is connected to the other end of the fan.

[0006] The other end of the suction pipe is connected to a sedimentation box. The air outlet of the sedimentation box is connected to a transfer pipe. The other end of the transfer pipe is connected to a filter box. The other end of the filter box is equipped with an air outlet pipe. A barrier screen is installed on the inner wall of the sedimentation box. A limit block is installed on the inner wall of the filter box. A filter screen is connected to the inner side of the limit block. A fixing block is connected to the inner wall of the filter box near the filter screen. A locking screw is connected through the surface of the fixing block. A sedimentation driving cylinder is installed on the surface of the sedimentation box. A filter driving cylinder is installed on the surface of the filter box.

[0007] In order to improve the pre-filtration effect, as a preferred embodiment of the dust removal device for processing multi-layer board pallets according to this utility model, the fan, sedimentation drive cylinder and filter drive cylinder are all electrically connected to the power supply on the pallet cutting table, and the barrier net is composed of four barrier plates spliced ​​together.

[0008] To facilitate the cleaning of attached sawdust, in a preferred embodiment of the dust removal device for processing multi-layer board pallets according to this utility model, the output end of the sedimentation drive cylinder passes through and extends into the interior of the sedimentation tank, and the output end of the sedimentation drive cylinder is connected to a sedimentation scraper.

[0009] To facilitate sawdust removal, in a preferred embodiment of the dust removal device for multi-layer board pallet processing according to this utility model, a sealed unloading window is connected to one side of the sedimentation tank via a hinge.

[0010] To improve the dust removal effect, in a preferred embodiment of the dust removal device for processing multi-layer board pallets according to this utility model, the surface size of the filter screen is adapted to the distance between the two limiting blocks, and the output end of the filter drive cylinder is connected to a filter scraper, the surface size of the filter scraper being adapted to the surface size of the filter screen.

[0011] To facilitate stable installation of the filter screen, in the preferred embodiment of this utility model of a dust removal device for processing multi-layer board trays, the locking screw passes through the fixing block and is threadedly connected to the opening on the side of the filter screen.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention involves placing a multi-layer board pallet on a pallet cutting table for processing. The sawdust generated during processing is then processed by a fan, creating negative pressure within the dust collection hood and drawing it into a sedimentation tank through a suction pipe. Larger sawdust particles are slowed down by a barrier screen and settled in the sedimentation tank. Smaller particles, after filtration, are transferred to a filter box through a transfer pipe and removed by a filter screen. The airflow is then discharged through an exhaust pipe. This process effectively collects sawdust waste generated during multi-layer board pallet processing, achieving dust removal and preventing uncontrolled dispersion of pollutants throughout the workshop, thus reducing maintenance costs.

[0023] Preferably, the fan 4, the sedimentation drive cylinder 61 and the filter drive cylinder 81 are all electrically connected to the power supply on the tray cutting table 1, and the barrier net 10 is composed of four barrier plates spliced ​​together.

[0024] Preferably, the output end of the sedimentation drive cylinder 61 passes through and extends into the interior of the sedimentation tank 6, and the output end of the sedimentation drive cylinder 61 is connected to a sedimentation scraper 62. In practical use, the sedimentation tank 6 facilitates the pre-filtration of large particulate impurities, preventing subsequent clogging.
