Description

Technical Field

[0001] This utility model relates to the field of wood panel edge banding technology, and in particular to a PVC edge banding strip cleaning device. Background Technology

[0002] Wooden furniture has become an indispensable part of modern furniture design. How to process high-quality and aesthetically pleasing wood panels has always been a research focus for wood processing plants. How to treat the edges and sides of the wood panels to improve their neatness and appearance has been a significant technical challenge in the industry. Edge banding strips are typically wound on a shaft to form a feed roll. When edge banding the boards, the edge banding strip is supplied to the edge banding machine through the feed roll. To ensure the quality of the edge banding, the edge banding machine must clean the wood chips and impurities from the bonding surface of the edge banding strip before edge banding, improving the cleanliness of the bonding surface.

[0003] For example, Chinese utility model patent application number 202421179358.0 discloses an edge banding cleaning device, including a frame, a horizontally oriented elongated base plate on the frame, and a feeding roll, a tensioning mechanism, and a cleaning mechanism arranged in sequence along the length of the base plate. An edge banding strip is wound on the feeding roll, and the outer end of the edge banding strip passes through the tensioning mechanism for tensioning, and is then cleaned by the cleaning mechanism. After that, it is conveyed to the edge banding machine, which cleans the adhesive surface of the edge banding strip by setting the cleaning mechanism to ensure the bonding strength between the edge banding strip and the furniture.

[0004] The aforementioned patent, which uses a brush to remove wood chips and impurities adsorbed on the bonding surface of the edge banding strip, lacks a dust suction structure to remove the brushed wood chips, impurities, and dust. This can easily cause wood chips to fly or dust to rise, polluting the working environment. Furthermore, the dust may be re-adsorbed onto the bonding surface of the cleaned edge banding strip, affecting the subsequent edge banding effect of the wood boards. This patent has certain limitations and needs improvement.

[0005] Therefore, it is necessary to provide a PVC edge banding cleaning device to solve the above-mentioned technical problems. Utility Model Content
