A tape preheating device for an edge banding machine

Abstract

The invention discloses an adhesive tape preheating device of an edge banding machine. The adhesive tape preheating device comprises an edge banding main body, an adhesive tape disc and a conveying belt, wherein a positioning rod is arranged on the adhesive tape disc, a heater is arranged on the adhesive tape disc, and a driver is arranged on the heater; a travel switch is arranged beside the conveying belt, a controller is connected to the travel switch, and a time delay unit and the driver are connected to the controller; after the controller is started, a heating signal is sent to the driver, and the driver responds to the heating signal so as to supply heating power to the heater; a triggering signal of the travel switch and a time delay signal of the time delay unit are read by the controller, and if the triggering signal is not read by the controller within the time delay signal, the heating signal is stopped to send; after the controller is started, the controller and the driverare conducted first within the preset time of the time delay unit, and an edge banding adhesive tape on the adhesive tape disc is heated by the heater; and if the triggering signal cannot be read bythe controller within the time delay signal, the driver and the controller can be disconnected by the time delay unit, and the heating power is stopped to supply, so that the edge banding adhesive tape is prevented from being excessively heated so as to band edges.

Description

technical field [0001] The invention relates to the technical field of edge banding technology design, more specifically, it relates to an edge banding machine tape preheating device. Background technique [0002] Edge banding machine is a highly automated machine that replaces manual edge banding procedures: conveying, gluing, cutting, front and rear alignment, up and down trimming, up and down fine trimming, up and down scraping, and polishing. It is mainly divided into semi-automatic There are two kinds of portable and portable, and they are used in the wood product processing and design industry. In winter, the edge-banding tape is brittle and hard, and it is easy to have edge-banding chipping when trimming. By installing an auxiliary preheating device on the edge banding machine, the edge banding belt will enter the trimming stage immediately after preheating, so as to avoid missing corners. [0003] For example, the edge banding machine disclosed by the Chinese paten...

Problems solved by technology

[0005] Aiming at the technical problems that the edge banding glue on the existing edge banding machine is used up or there is no wood product on the edge banding machine, the heating operation is still carried out during processing, which wastes energy, and even causes the edge banding tape to overheat and cannot be edge banded. The present invention provides a Edge banding machine tape preheating device, which has the advantage of stopping heating when there is no edge banding tape or no wood products on the edge banding machine, so as to avoid the overheating of the rubber strip and the advantage of not being able to seal the edge
