Abstract

The invention provides a preheating structure, and belongs to the technical field of packaging. The preheating structure comprises a first preheating block and a second preheating block, wherein the first preheating block is fixedly connected with a rack; the second preheating block is movably connected with the rack and has a preheating state parallel to the first preheating block, and in the preheating state, a preheating gap is formed between the two opposite heating surfaces of the second preheating block and the first preheating block; the second preheating block also has a maintenance state far away from the first preheating block, and in the maintenance state, a maintenance space convenient for cleaning the heating surfaces is formed between the second preheating block and the firstpreheating block; and heating parts are arranged on the first preheating block and / or the second preheating block. According to the preheating structure, the space distance between the second preheating block and the first preheating block is adjusted through rotation adjustment of the second preheating block, so that the second preheating block has enough maintenance space to clean the heating surfaces of the first preheating block and the second preheating block, and cleaning difficulty caused by insufficient space is avoided; and in the low-speed preheating state, the preheating gap can beopened by a certain angle, and materials are prevented from being molten and bonded.

Description

technical field [0001] The invention relates to the technical field of packaging, in particular to a preheating structure. Background technique [0002] In the packaging industry, plastic packaging bags are generally sealed by heat sealing; in order to increase the strength of the seal, the bag mouth is preheated first, and then the preheated area of ​​the bag mouth is rolled and sealed horizontally. [0003] The preheating structure adopted in the prior art is a fixed structure, that is, a pair of preheating blocks are fixed at the corresponding installation positions of the equipment. In order to achieve the expected preheating effect, the preheating gap is generally small. [0004] For the above-mentioned preheating structure, when cleaning or maintaining, due to the small preheating gap, it is difficult to clean up the impurities such as overflow glue and dust on the heating surface of the preheating mechanism. Contents of the invention [0005] Therefore, the technic...
