Large-span double-end edge banding machine

Abstract

The invention discloses a large-span double-end edge sealing machine which comprises a framework and a transmission chain control device. The transmission chain control device comprises two transmission chains; an upward glue applying device and an edge sealing machine body mechanism are sequentially arranged on the outer side of each transmission chain; hooks are arranged on the transmission chains, can outwardly extend out of the upper sides of chain blocks under the effects of push-up mechanisms and can be driven to be inwardly retracted to the lower sides of the chain blocks under the effects of pull-down mechanisms. The large-space double-end edge sealing machine has the advantages that the hooks can be pushed out or withdrawn according to requirements, so that plates can be positioned and can be conveyed stably and accurately; glue can be applied and coated vertically separately, so that the volume of a glue box can be reduced, the glue hot melting time can be effectively shortened, energy consumption and the cost can be reduced, the production time can be prolonged, pyrolysis and carbonization of the hot melt glue can be prevented, and the quality of products of users can be improved; the glue does not need to be frequently applied, and accordingly the large-span double-end edge sealing machine is high in glue supply quantity and glue coating altitude, suitable for thick plates and high-speed edge sealing operation and high in efficiency, and has high value.

Description

technical field [0001] The invention relates to the technology in the field of woodworking machinery, in particular to a large-span double-end 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 wood strips. Edge banding strips of d...

Problems solved by technology

[0010] In view of this, the present invention aims at the deficiencies in the prior art, and its main purpose is to provide a large-span double-end edge banding machine, which can effectively solve the problem that the transmission chain of the existing edge banding machine cannot position and transport the boards. The glue adding device has the disadvantages of long hot melt glue time and insufficient glue supply, which lead to the problem that the quality and efficiency of edge banding are affected

[0011] The second purpose of the present invention is to provide a large-span double-end edge banding machine, which can effectively solve the problem that the existing synchronous shaft mechanism is complicated to install and debug, and it is difficult to ensure the synchronous operation of the two transmission chains

[0012] The third purpose of the present invention is to provide a large-span double-end edge banding machine, which can effectively solve the problem that the transmission chain of the existing edge banding machine is prone to looseness and cannot maintain a tensioned state
