Spiral upper-end glue feeding device of automatic edge bonding machine

Abstract

The invention discloses a spiral upper-end glue feeding device of an automatic edge bonding machine. The spiral upper-end glue feeding device comprises a frame, a hopper-type housing and a glue core melting component. The glue core melting component comprises a shell, a screw rod and a reducing pneumatic motor. The shell comprises a shaft sleeve seat and a heating cylinder. Heating devices sleeve the heating cylinder. The lower end of the heating cylinder is provided with a diversion pipe communicated with a flow channel. The screw rod is matched with the flow channel and rotatably arranged in the same. A heating pipe is arranged in the lower end of the screw rod. The spiral upper-end glue feeding device has the advantages that the the heaters sleeving the heating cylinder are high in power and heat transferring efficiency, the screw rod extrudes hot melt glue for plasticizing, and glue melting speed is high, besides, by heating in the screw rod and constantly rotary stirring, mixing and extruding under driving of the reducing pneumatic motor, the melt glue is constantly extruded out of the heating cylinder, thus the problems of the traditional cylinder extruding glue of idle running and melting difficulty of solid particles in a cylinder glue extruding cylinder core are solved, and glue melting efficiency and quality is effectively increased.

Description

technical field [0001] The invention relates to the technology in the field of wood processing equipment, in particular to a spiral-type upper end glue supply device of an automatic edge banding machine. Background technique [0002] Edge banding is an important process in the manufacturing process of panel furniture. The quality of edge banding directly affects the quality, price and grade of products. The appearance quality of the furniture can be improved by sealing the edge, avoiding damage to the corners of the furniture during transportation and use, and the veneer layer being lifted or peeled off. At the same time, it can play the role of waterproofing, sealing the release of harmful gases and reducing deformation. , but also beautify the furniture, happy mood. The raw materials used by panel furniture manufacturers are mainly particle board, medium density board and other wood-based panels, and the edge banding strips used mainly include PVC, polyester, melamine and...
