Description

Edge bonding machine

Technical Field

The invention relates to the technical field of edge bonding machines, in particular to an edge bonding machine.

Background

The edge bonding machine is a processing device which is commonly used for processing products such as wood furniture and the like, and the edge bonding machine is mainly used for bonding edges of boards and comprises a milling cutter guide plate mechanism, a pressing mechanism, a trimming mechanism, an edge scraping mechanism and other components for realizing edge bonding. In the conventional edge bonding machine, for example, the chinese invention application with publication number CN114619539A, when the thickness of the edge bonding tape needs to be changed, the direct distance between the guiding plate, the pressing wheel, the trimming cutter, the edge scraping cutter and other components and the plate material to be edge bonded needs to be manually adjusted, so that the distance can adapt to the thickness of the edge bonding tape. The manual focusing mode is adopted, so that not only is the automation degree low and the efficiency is low, but also the final edge sealing effect is uneven due to the fact that the adjusting distance is not ideal enough due to the technical level of operators, and the product processing quality is affected.

In addition, in the conventional edge bonding machine, for example, in the invention patent with publication number CN106426503B, the gluing mechanism, the belt feeding mechanism and the pressing mechanism are driven by the same gluing motor (refer to fig. 3 and 4 of the drawings in the specification of the invention patent), although this design may bring about a lower price, the structure itself is also designed to be the gluing shaft of the gluing mechanism and the belt feeding shaft of the belt feeding mechanism, and the surface linear speeds of the pressing wheels of the pressing mechanism are equal, but in actual use, the speeds of the three mechanisms are different due to factors such as the tolerance of parts and the tightness of the transmission chain, thereby affecting the edge bonding quality.

In addition, in order to switch the cutting edges corresponding to different arc angles, the conventional edge bonding machine often does not have such a function, does not have a very complicated structure, and is difficult to switch the different cutting edges quickly and conveniently to adapt to edge bonding processing of the corresponding edge bonding belt thicknesses under different arc angles (for example, two arc angles of R1.5 and R1).
