Vacuum-free surrounding coating machine

Abstract

The invention relates to the technical field of surrounding coating machines, in particular to a vacuum-free surrounding coating machine. The vacuum-free surrounding coating machine comprises a rack, a fabric supply device arranged on the rack, a backing material supplying and positioning device, a coating forming device, a cutting forming device, a material conveying device and an electrical control system, wherein the fabric supply device comprises a fabric rolling frame, a fabric guide rod, a fabric guiding, positioning and regulating block, a fabric detecting pressure plate, a bottom paper release reel and an anti-adhering pressure roller which are sequentially connected through fabric; and the backing material supplying and positioning device comprises a supporting frame, a backing material length positioning regulating block arranged on the supporting frame, a backing material positioning supporting baffle block, a material supply air cylinder and an unloading pressure plate air cylinder. The vacuum-free surrounding coating machine can simplify equipment regulation operation, expands range of application of the material type and the product dimension processed by the vacuum-free surrounding coating machine, increases an adaptable product rate of the surrounding coating machine, and improves operation stability of the surrounding coating machine, so that production efficiency is improved.

Description

Technical field [0001] The invention relates to the technical field of edge wrapping machines, in particular to a non-vacuum edge wrapping machine. Background technique [0002] The automatic edge wrapping machine is used for mass production of all kinds of packing boxes. The automatic edge wrapping machine has a wide range of applications in the packaging field. However, the automatic edge wrapping machine in the prior art has the following problems: (1) The existing edge wrapping machine limits the edge material to be gray board paper, and the edge material is flannel, and it is not suitable for production The production of covering fabrics with a large width and adjustable range above 30mm, therefore, the adjustable range of size is single, and the applicability of materials is severely limited; (2) The existing edge covering machine needs to be carried out by vacuum adsorption When conveying gray board paper, because the vacuum suction hole is easily blocked by flannel dust,...

Problems solved by technology

However, the automatic edge wrapping machine in the prior art has the following problems: (1) The existing edge wrapping machine limits the edge material to be gray board paper, and the edge material is flannelette, and cannot be used in production The production of covering fabrics within the wide adjustable range of more than 30mm, therefore, the size adjustable range is single, and the applicability of materials is severely limited; (2) The existing edge covering machine needs to be carried out by vacuum adsorption Conveying gray board paper, because the vacuum adsorption hole is easily blocked by flannelette dust, causing the dust to be stuck in the pressing place, affecting the positioning of the gray card, resulting in serious product quality problems; (3) the existing edge wrapping machine The start-up time is as long as 2 hours. If the vacuum adsorption hole is blocked, it needs to be restarted for debugging, which seriously affects the production efficiency; (4) It is difficult to adjust the pressing part, the balance of pressure and tension is difficult to control, and the material is easy to get stuck at the pressing plate. , resulting in quality problems due to poor pressing of the fabric
