Matchmaking process

Manufacturing process of matches

The manufacturing process of matches varies by variety

Manufacturing of matches with wood stems can be roughly divided into There are 5 parts: stalk manufacturing, stalk processing, match tip manufacturing, box manufacturing, packaging and phosphorous brushing.

①Stalk manufacturing: The matchstick should be made of wood with loose texture, straight texture, flammable and no peculiar smell. Commonly used tree species are poplar or linden, but also pine or spruce. Pine wood is cooked to remove turpentine.

After the material is selected, the logs are sawn into sections, the bark is peeled off, and it is spun into continuous stalks of uniform thickness. The stalks are then cut into stalks of a certain size.

2 Treatment of stalks: The stalks are soaked with phosphoric acid or ammonium phosphate solution with a concentration of about 1%, which is called anti-burning treatment, which can prevent the embers from falling after the matches are burned. After draining to remove the surface moisture, it is sent to the stem drying machine for drying, so that the moisture content of the stem stems is reduced to 6-8%. After the stalks are dried, they are screened by a stalk selection machine to remove the broken branches and long and wide pieces, and select the stalks that meet the specifications.

③Manufacture of match tip: qualified stems and branches are sent to the match automatic continuous machine through wind pipes or conveyor belts, and automatically carry out stem trimming, stem loading, waxing, medicine soaking, drying and stem unloading, etc. Dao craftsmanship, that is, to complete the production of matches.

④Matchbox manufacturing: Matchboxes are divided into two types: paper boxes and wooden boxes. The carton is made of rolled cardboard or flat paper with a thickness of 0.4mm and a basis weight of 300g/m2. The paper separator divides the original roll board into different widths to meet the production needs of the outer box or the inner box. After the inner and outer boxes are prepared separately, the boxes are assembled to form a whole. The wooden box is made of wood segments with better material and no scars, and the inner or outer box pieces with scratches are unscrewed on the rotary box machine, and then cut into box strips respectively. Boxes, labels.

⑤Packaging and phosphorus brushing: matches and matchboxes converge in the packaging process. The cartoning machine puts the matches neatly into the box according to the specified count, and then the phosphorus brushing machine brushes the phosphorus slurry on the side of the box. Another kind of phosphor surface is printed on the side of the box when printing the trademark, which is called “printing phosphor surface”. The main components of phosphorus paste are red phosphorus and binder. The traditional adhesive is leather glue, but now synthetic adhesives are also used. After drying, the packaging machine will seal each 10 boxes of matches into small packages and put them into boxes (100 packages in a small box, called “pieces”; 200 packages in a large box, called “double pieces”), which is the finished product.

Wax Stick Matchmaking Wax sticks are manufactured in two ways: one is die-drawing and the other is extrusion. It all goes through the process of raw paper slitting, wax dipping, forming, cooling and cutting. It uses a roll of glossy paper with a quantitative 40-45g/m2 as the raw material, and cuts it into coiled paper with a width of 20-25mm, and forms a round or square shape in the molten paraffin at a temperature of about 120 ℃ through a forming die or forming wheel. The stalks of the cross-section are cut into stalks after being cooled by cold water or cold air to form a shape. The specifications of wax stems are generally 28-38mm in length, 1.5mm in diameter for round stems, and 1.6×1.6mm in section for square stems.

The manufacture of match tips is the same as that of wood-stem matches. After stemming, it enters the ordinary match continuous machine, dipped in medicine, and made into matches. But do not need to dip wax before dipping medicine. The bonding fastness of the wax stalk and the medicine head is poor. Before dipping the medicine slurry, it needs to be pretreated to remove the wax layer on the surface of the end of the stalk (the place where the medicine is dipped), and loosen the paper layer slightly to increase the number of medicine heads and stalks. The drying of the head is carried out at a lower temperature (20 ~ 40 ° C) to avoid melting of the paraffin in the stem.

Manufacture of paper-stem book-style matches is divided into three parts: stem making (commonly called match comb), cover making and binding. In order to prevent the residual branches from smoldering after the paper stems are burned and extinguished, the cardboard used for making stems needs to be treated with anti-burning treatment. This treatment is the last step in the production process of cardboard, that is, before the paper blank passes through the final dryer, it is evenly sprayed on the cardboard with a 5% aqueous solution of diammonium hydrogen phosphate, and then dried, and the moisture content should be kept at 8 %about.

Adopt the match comb automatic continuous machine (CM machine) to automatically complete the stem making and the dipping head. Use the cover phosphorus coating slitting machine (PM machine) to coat the printed cover paper with a phosphorus layer. After drying in the drying tower, it is firstly cut into strips longitudinally and then transversely into slices for packaging. . The match comb and the cover are combined in the binding machine (AM machine), the match comb is cut on the machine, and the cover is folded and bound into a book, which is the finished product.
