Cartons through the device of small enterprises to transform tap potential – cardboard boxes, equipment, and potential – Paper Industry
Currently, Carton Industry faces rising prices of raw materials and carton prices will be difficult to control and profit margins become smaller and smaller situation, in order to reduce the carton costs and take more market share, many enterprises in the base paper cartons moving a lot of selection on brains?? a low weight to the base of low-level production. The technical quality of the workers and the original state of production equipment limitations, it is difficult to produce satisfactory products, often in poor adhesion? Serious bent? Cardboard soft case. Carton plant this do nothing. So, is there a solution then? This will be a cardboard box on the transformation of enterprises to illustrate how the paper under the circumstances and equipment construction companies were "small reform", in order to tap the potential of upgrading product quality to enable enterprises to burst out of energy.
Example of a company using a domestically produced line of five cardboard, better site management, the board well-organized workshops, equipment, maintenance is not bad, but production of cardboard point of view, common soft ? less smooth and Corrugated Pour flute serious phenomenon?? Measured with a caliper thickness of less than five board 7 mm. Most of them matching the paper from 110 to 125 grams in between, with special requirements of corrugated carton used 130 grams or 110 grams applied adhesive tape, and each must be a shovel paperboard combination with 9 fans for hair treatment, the water vapor Chuijin cardboard in order to increase the hardness of cardboard. Some use heavy cardboard as severe bending of the heap pressure, resulting in cardboard surface wrinkles? Crease. The overall quality of the product gives the impression less. The following appeared on the actual production issues to analyze and find out the solution.
Comprehensive analysis of the product obtained after the cause of these conditions, there are four reasons: first, excessive glue cause cardboard soft? Serious bent? Not high enough; second bridge on the previous two cardboard approach is not suitable for the present paper through the production of low weight paper, the actual situation, this would have caused some corrugated shape of the injury; third double-adhesive paper roll-off gap inappropriate; the fourth is a compound machine on the hot plate gravity roller is not adjusted correctly according to requirements.
Analysis and implement the Equipment from the current situation and the workers usually accustomed to the operation point of view, the equipment part of the structure there are some defects, because the machine's structure is designed in accordance with the production of heavy cardboard boxes, unable to adapt to low-weight paper production. Therefore, to bridge the way through to make changes on paper, so that the two low-weight paper, corrugated board in the wear process to minimize damage, and avoid the corrugated deformation. For these considerations lead to the bridge on the paper planes were some changes, changed the way the original warm-wore paper. Double-checking on the glue machine rubber roller, other than to find defects on the device, also found the operational errors. Because the original glue roller which resulted in the board often blistering phenomenon degumming operation workers in order to avoid the occurrence of the phenomenon degumming, blindly increasing the glue, so that the moisture content of cardboard far exceeded. This is a completely erroneous understanding that there may be many manufacturers will have such a misunderstanding. Measuring two double coater glue roller and pressure roller gap over paper, and found that over two on Roller Paper space requirements significantly smaller than the actual number of, and having the gap is too small is a severely shocked the the main reason.
The finding of a few points, first proposed to reform of the adhesive roller to require processing units according to our technical requirements for processing, and personally supervise the processing of the quality of processing units. After installation, confirmed by the production changes due roller, so that the glue did not significantly effect the same basic control on the width of the corrugated plastic peak 1 mm to 1.5 mm, the reduction of plastic than the original more than half, and glue Coating Quite uniform. Finally, roll the hot plate and gravity carried out as required careful adjustments, look at the quality of produce cardboard case, not the phenomenon of inverted flute, and board thickness up to 7.7 mm, not only remove the hair in the process, and paperboard significantly increased the hardness does not need to board a heavy heap pressure.
Equipment is original equipment, or used in the original paper, but the production of the product is entirely different. Facts have proved that the machine can also be made to produce first-class products. Scientific transformation of the equipment? Precise adjustments to ensure product quality and reduce production costs an important factor.
