Description

Round pressing round die cutting equipment suitable for single paper

Technical field:

the structure is applied to the range of single paper die-cutting equipment.

The background technology is as follows:

at present, most of the production processes adopted in various domestic big cigarette packet printing factories are the following two types of cigarette packet products due to the printing process requirements: and (3) rewinding by a rewinding device after the printing is finished by the first process and the printing machine, and then transferring to an off-line round pressing and round die cutting machine for embossing, indentation and die cutting to finish the forming of a final product. And after the printing is finished by the printing machine, cutting the large sheet by a self-contained transverse large sheet device, cutting the printed product into large sheets with fixed length according to typesetting by the device, and then transferring the large sheets to a flat pressing and flattening device for embossing, indentation and die cutting to finish the final forming of the product. The subsequent equipment of these two production processes is directed to the web and the sheet, respectively. They each have various advantages and disadvantages. The off-line circular pressing circular die cutting machine for the roll paper has the advantages that: 1. because the round pressing round is continuously die-cut, the typesetting does not need a bleeding position, so that the paper waste can be greatly reduced, and objective economic cost is saved; 2. the continuous rolling cutting is adopted, so that the production efficiency is high; 3. the degree of integration of functions is high. The round pressing die-cutting machine adopts automatic wire connection quality inspection, automatic waste shaving, automatic collection and stacking and automatic bundling, and the discharged products can be directly packaged. The device has the defects of high equipment cost, high technical threshold of consumable materials such as cutters and the like and high replacement cost. The process is suitable for long-line large single products. The flat pressing device for the single paper has the advantages of 1, low equipment cost and low flat pressing knife plate cost for die cutting. Its disadvantages are: 1. because of die cutting of single paper, the paper is required to be transferred by the splice bleeding and the gripper with larger size, so that a lot of paper is wasted, and the economic cost is high; 2. the intermittent die cutting is adopted, so that the production efficiency is low; 3. the integration level of the device functions is not high. Although the flat-pressing device has been provided with the function of completely clearing waste in the last two years, the waste cleared products are still connected together by connecting points and output in a flat state. The product is separated by a separate separating device, and then transferred to a separate quality control machine for quality control and waste shaving. The process is suitable for the production of small batches of single sheets. In the production process requirements of tobacco bale products, a gold stamping process is needed on many products, and the gold stamping patterns are only suitable for gold stamping on flat plates due to the specificity of the patterns, so that the products are required to be cut into large sheets.

The products of other tobacco companies in the world are basically round-press round-die cutting equipment which is connected or disconnected, and the equipment sold by several large international die cutting equipment manufacturers is also basically round-cut for roll paper and flat-cut for single paper. Very individual companies like gaobao have circular cutting equipment for single sheets of social products on the market, but the equipment also uses the principle of a single sheet printer to realize the transfer of the sheets through gripper bars and grippers, and the problems of production efficiency and sheet cost are not solved at all.

Through research and analysis to market, combine self advantage again, propose a special circular press circular die cutting equipment that is applicable to single paper, this equipment not only can realize circular press circular die cutting with single paper product, can also realize functions such as online quality control, reject, transport, collection, pile up neatly, can also realize the paper that does not have holding mouth of single paper printed product simultaneously to practice thrift the paper cost. The appearance of the equipment can greatly improve the existing production process. At the same time, the equipment also provides more production process options for customers.
