Portable rapid welding tool for PU round belt

Abstract

The invention relates to the field of PU round belt machining, and discloses a portable rapid welding tool for a PU round belt. The tool comprises two hinged clamp bodies, a hot melting device is arranged in the crossed and hinged position of the two clamp bodies, a battery is embedded in a first clamp handle, a heating control main board and a heating control button are arranged on a second clamp handle, the heating control main board is electrically connected with the heating control button, the battery and the hot melting device, the hot melting device comprises a hot melting positioning mechanism and a heating piece fixedly connected with one end of the hot melting positioning mechanism, and connection positioning structures are arranged at the ends, used for connection, of a first interface fixing device and a second interface fixing device correspondingly. The hot melting device is integrated to the clamp bodies, and the battery and the heating control main board are arranged, so that a handheld hot melting device does not need to be additionally arranged, and use and carrying are convenient; a hot melting device positioning device is arranged, and stable conveying and accurate positioning of the placed heating piece are achieved through a push rod and a self-locking reset device; the connection positioning structures are arranged, and accurate positioning of accurate connection is achieved through two step end surfaces.

Description

technical field [0001] The invention relates to the field of PU round belt processing, in particular to a portable PU round belt rapid welding tool. Background technique [0002] PU round belt is a commonly used connectable pipe belt. For example, the patent name of the applicant’s previous application is a simple PU round belt connection tool, the patent number is 202021094980.3, and the announcement number is CN212603506U. The Chinese utility model patent, the existing Although the PU round belt connector is easy to use and operate, usually when the joints at both ends of the PU round belt are connected, the joints at both ends of the PU round belt are in the hot-melt process, and an additional hand-held fuser is required to cut in. The melting method has the following disadvantages: [0003] ①Because it is hand-held and there is no positioning reference, it can only be positioned with the naked eye based on experience. Insufficient experience, it is easy for the fuser to...

AI Technical Summary

Problems solved by technology

[0003] ①Because it is hand-held and there is no positioning reference, it can only be positioned with the naked eye based on experience. Insufficient experience, it is easy for the fuser to melt the joints on both sides of the round belt. Due to hand shaking or visual deviation, the end faces of the joints on both sides of the round belt are uneven, causing the interface The bonding is not strong and needs to be re-welded;

[0004] ②In the connection of the existing technology, there is no positioning reference on the connection end surface, and the two ends are prone to deviation, resulting in incomplete connection or overpressure of the interface during connection, resulting in excessive flow of glue, requiring re-welding;

[0005] ③When going out to work, you need to carry an additional hand-held fuser, which is very inconvenient, and the fuser is separated from the connection tool, which is easy to forget and inconvenient to carry
