Point contact type conveying chain

Abstract

The invention discloses a point contact type conveying chain which is composed of inner chain links, connection sheets and steel balls. The connection sheets are arranged at the left end and the rightend of the inner chain links, the steel balls are arranged on the connection sheets, and therefore a whole point contact type conveying chain is formed. In the application process of the point contact type conveying chain, when plates coated with glue are conveyed to the point contact type conveying chain, only some round points composed of the steel balls need to move synchronously to receive and convey the plates, since plate contact faces are small, the glue on the plates is not brought away, the phenomenon that the plates evenly coated with glue originally are lack of glue or short of glue is avoided, therefore, a manual loss and a glue loss are avoided, and the adhesion face gluing effect is also not affected. By applying the point contact type conveying chain, the glue on the platesurfaces coated with glue is not brought away through conveying equipment, the good gluing effect is effectively ensured, the glue lack and short phenomena are reduced, and a quality guarantee is provided for the next step of veneer pressing working procedure.

Description

technical field [0001] The invention belongs to a matching part of a new type of board feeding equipment, and in particular relates to a point-contact conveying chain. technical background [0002] my country is a big producer of plywood, with an output of 170 million cubic meters in 2016. In the production process of plywood, the last veneering process is very critical. Before veneering, it is necessary to evenly apply glue on the two major surfaces of the semi-finished substrate, and then cover it with a thin wood veneer, glue and press it. [0003] When the traditional boards implement the above process, the glue is applied by the glue machine and the boards that have been coated with glue are picked up in the following three ways, and then the post-process veneer processing is carried out: [0004] 1. Manual board connection: After the board coated with glue is rolled out by the glue applicator, two people will manually join, transport and veneer the board at both ends ...

Problems solved by technology

This method is not only labor-intensive and time-consuming, but also has low output and high energy consumption.

[0006] 3. Double-sided gluing: The glue-coated board is sent out by the glue machine and then sent by the roller. This method is efficient, but when the roller feeds the board, the board will be on the surface of the roller when it touches the surface of the roller. If the glue is taken away, it is easy to cause less glue or lack of glue on the plate that has been evenly glued, and then affect the quality of the veneer
