Problems solved by technology

[0005] The current pressure control mainly relies on experience for adjustment, and repeated adjustments and tests are required in the actual production process. In addition, in the actual production process, for different product batches, the sealing performance of small cigarette packs varies greatly, and it is impossible to guarantee the sealing performance of each pack. The sealing quality of the product

Embodiment 1

[0155] (1) Obtain information on the production factors of the brand, including information on equipment used, transparent paper materials, and small box trademark materials.

[0156] a. It is known that the cigarettes of this brand are produced in medium-speed equipment, and the operating speed of the equipment is 400 packs / min;

[0157] b. Using transparent paper material A, according to the melting point temperature of the transparent paper material and the heat-sealing temperature setting table information of the equipment operating speed, the corresponding heat-sealing temperature range of the transparent paper material is [144°C, 152°C];

[0158] c. The grammage of the trademark leaflet in the small box is m2, and according to the comparison table of trademark single weight and heat-sealing distance, the heat-sealing distance is [87.2mm, 87.6mm].

[0159] (2) Set the initial heating temperature of the heat-sealing plate, and take the median T0 of the heat-sealing tempera...

Embodiment 2

[0169] After the equipment has been working for a period of time, it is necessary to detect and determine the effectiveness of the heat-sealing plate. It is known that the heat-sealing temperature range corresponding to the transparent paper material is [145°C, 155°C], and it is necessary to control the standard deviation S≤2.8 and the range R≤ 8.

[0170] (1) The equipment is powered on, and the initial heating temperature is set to T0 = 150°C;

[0171] (2) Detect the temperature of the heat-sealing plate with a thermal imager;

[0172] (3) Calculate the average value of the temperature at each location point 〒=147°C, standard deviation S=2.5, range R=5, S and R all meet the requirements;

[0173] (4) According to the deviation ΔT between T0 and 〒, correct the heat sealing setting temperature to be T0+ΔT before production.

Embodiment 3

[0175] According to the comparison table between the weight of the small box sheet paper and the distance between the heat seals in the above table 2, select a certain brand product, and during the production process of changing the brand, conduct a verification test on the setting effect of the distance between the two heat seal plates, and select the heat seal of this brand. Any numerical value within the spacing interval is set as the initial heat-sealing spacing.

[0176] After the normal production of the product, in addition to the small packs that are fixedly rejected by the initial stage of the equipment, continuous sampling of 200 packs of small packs that normally flow into the subsequent process is carried out to test the sealing degree of the small packs and the appearance quality of the packaging, and the quality is qualified. The rate is 100%.

[0177] Compared with the previous production process of changing brands, the workshop often needs to repeatedly adjust ...

Abstract

The invention relates to a method for heat sealing a small cigarette packet. The method comprises the following steps of before heat sealing, adjusting spacing between two opposite heat sealing platesaccording to a preset heat sealing spacing; and operating equipment to carry out heat sealing on the small cigarette packet, detecting whether the sealing of the heat sealed small cigarette packet meets the requirement or not, if yes, continuing heat sealing production, and if no, readjusting the spacing between the two heat sealing plates. According to the method, the spacing between the two heat sealing plates can be preliminarily adjusted according to the preset heat sealing spacing, part of samples can be heat sealed firstly to determine whether the adjusted spacing is appropriate or not,if yes, subsequent production is carried out, and if not, the spacing is readjusted; the sealing performance of the small cigarette pack can be improved by controlling the pressure of the heat sealing plates and the small cigarette pack, the sealing stability of the product during batch production is improved, and the quality risks such as mildew of the cigarette product due to poor sealing are reduced; and moreover, by means of the method, the heat sealing production efficiency can be improved, and unqualified products can be reduced.

Description

technical field [0001] The invention relates to the technical field of cigarette packaging, and in particular designs a heat-sealing method for small packs of cigarettes. Background technique [0002] Transparent paper is used as an auxiliary material for internal packaging in the tobacco industry. Its function is mainly to ensure the quality of cigarette products and prevent products from being damp and polluted. At present, the packaging equipment for small boxes of transparent paper in the industry consists of two heat-sealing plates, which respectively seal the front and rear of small boxes of cigarettes. The transparent paper at the end is heat-sealed. There is a layer of coating on the working surface of the heat sealing plate, which is used for heat preservation and anti-friction functions. [0003] Its working principle is: when the small packs of cigarettes enter the transparent paper heat-seal along the conveying track, the left and right cylinders respectively pu...
