Continuous heat-sealing device for back-glue bags

Abstract

The invention discloses a continuous heat-sealing device for back-glue bags. The device structurally comprises a supporting cabinet, an electric control box, a back-glue bag starting point winding reel, a power roller, a pressing roller, a case, a heat-sealing base plate, a double-heat-sealing-machine body, a guiding roller, a case door and a back-glue bag end point winding reel; the electric control box is arranged in front of the supporting cabinet and is connected with the front surface of the supporting cabinet through electric welding; the electric control box is electrically connected with the power roller, the double-heat-sealing-machine body and the back-glue bag end point winding reel; the back-glue bag starting point winding reel is arranged above the supporting cabinet and is perpendicularly welded to the supporting cabinet through a supporting rod; and the power roller and the pressing roller are arranged on the upper side of the inside of the supporting cabinet. The devicehas the beneficial effects as follows: heat-sealing work is performed on the back-glue bags through two heat-sealing machines of the double-heat-sealing-machine body alternately, timed glue scrapingis performed on a heat-sealing block while the heat-sealing continuity is guaranteed, the influence on the heat conductivity due to the fact that much residual glue adheres to the heat-sealing block is prevented, the heat-sealing efficiency of the continuous heat-sealing device for the back-glue bags is effectively improved, and the heat-sealing quality of the back-glue bags is guaranteed.

Description

technical field [0001] The invention is a continuous heat-sealing device for adhesive bags, which belongs to the field of adhesive bag processing equipment. Background technique [0002] The plastic back bag is a bag made of PE or PP material with self-adhesive glue on the back. It is mainly used for the shipment of product transportation transfer bills, bills of lading, invoices, and safety data. The self-adhesive adhesive on the back of the envelope can be pasted on any surface, and it is convenient and easy to use. The sealing of the adhesive bag can be made into a sealed form, which can ensure the safety of the documents in transit and convey the relevant information completely and accurately. [0003] However, the continuous heat-sealing device for adhesive bags in the prior art cannot perform glue scraping on the heat-sealing block during continuous heat-sealing work, resulting in more glue sticking to the heat-sealing block, which affects its thermal conductivity and...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a continuous heat sealing device for adhesive bags to solve the problem that the continuous heat sealing device for adhesive bags in the prior art cannot perform glue scraping on the heat sealing block during continuous heat sealing work. Causes more glue sticking on the heat-sealing block, which affects its thermal conductivity and reduces the heat-sealing quality of the adhesive bag
