重型纸箱的尺寸如何进行计算?

1.内外径及制造尺寸的计算
1. Calculation of internal and external diameters and manufacturing dimensions
内径尺寸的确定因素主要有内装物大外径尺寸、按内装物形式确定的公差系数、内装物排列方式、内装物隔衬与缓冲件的相关尺寸。内径尺寸的计算可由下式得到:Xi=Xmaxnx+d(nx-1) +k’ +T。式中,Xi为纸箱内径尺寸;Xmax为单个内装物大外径尺寸;d为内装物在纸箱内某一方向的排列数目;k’为纸箱内径尺寸补偿量;T是隔衬或缓冲件总厚度。长度单位均为mm。需要满足Xi >内装商品的外径尺寸。修正系数及公差系数可查表得到。
The determination factors of the inner diameter dimension mainly include the large outer diameter dimension of the interior, the tolerance coefficient determined according to the form of the interior, the arrangement of the interior, and the relevant dimensions of the interior spacer and buffer. The inner diameter dimension can be calculated by the following formula: xi = xmaxnx + D (nx-1) + K '+ t. Where Xi is the inner diameter of the carton; Xmax refers to the large outer diameter of a single interior; D is the arrangement number of contents in a certain direction in the carton; K 'is the compensation for the inner diameter of the carton; T is the total thickness of the spacer or buffer. The unit of length is mm. It is required to meet Xi > outer diameter dimension of internal goods. The correction coefficient and tolerance coefficient can be obtained from the table.
制造尺寸的计算为:X=Xi +t +k 。式中, 为瓦楞纸板制造尺寸, 为纸板厚度, 为修正系数。 值的大小与纸箱的具体尺寸有关。在实际使用过程中,由于内摇盖的回弹作用,使其有向外翘起的趋势。为减少由于这种原因而造成的净空高度增加,高度方向上的值应为2t
The calculation of manufacturing dimension is: x = Xi + T + K. Where, is the manufacturing size of corrugated board, is the thickness of board and is the correction coefficient. The size of the value is related to the specific size of the carton. In the actual use process, due to the rebound effect of the inner swing cover, it tends to tilt outward. In order to reduce the increase of headroom caused by this reason, the value in the height direction shall be 2T
外径尺寸计算为:X0=X+K。式中,X0为外径尺寸,K为修正系数。
The outer diameter dimension is calculated as: x0 = x + K. Where x0 is the outer diameter dimension and K is the correction factor.
2.纸箱摇盖尺寸的计算
2. Calculation of carton flap size
瓦楞纸箱外摇盖的制造尺寸也是需要注意的一个关键部位。在瓦楞纸箱外摇盖对接封合的箱型中,如0201、0204、0207等,摇盖宽度制造尺寸理论值应为箱宽制造尺寸的二分之一。但是,由于内摇盖的回弹作用,箱盖合上后并不是水平的,而是略倾斜,外摇盖必然在对接处产生一定的间隙。因此,外摇盖的宽度并不是宽度的一半,而是稍长,所以在实际的生产中要加上一个放大系数。放大系数可以通过三角函数计算得出。不过,由于纸箱自身的可塑性,也为了便于计算,多数企业都根据纸板的厚度计算出一个固定的放大系数。如下表所示:

The manufacturing size of corrugated box outer swing cover is also a key part that needs attention. In the case of butt sealing of corrugated box outer swing cover, such as 0201, 0204, 0207, etc., the theoretical value of manufacturing dimension of swing cover width shall be half of the manufacturing dimension of box width. However, due to the rebound effect of the inner swing cover, the box cover is not horizontal after closing, but slightly inclined, and the outer swing cover must produce a certain gap at the butt joint. Therefore, the width of the outer swing cover is not half of the width, but slightly longer, so an amplification factor should be added in the actual production. The amplification factor can be calculated by trigonometric function. However, due to the plasticity of the carton itself and for ease of calculation, most enterprises calculate a fixed magnification factor according to the thickness of the cardboard. As shown in the following table:
纸箱摇盖的放大系数
Magnification factor of carton flap
纸板厚度 3 mm以下 3 mm~5 mm 5 mm~8 mm 8 mm~12 mm
Paperboard thickness less than 3 mm 3 mm ~ 5 mm 5 mm ~ 8 mm 8 mm ~ 12 mm
放大系数 无 加大1 mm 加大3 mm 加大4 mm
The magnification factor is not increased by 1 mm, increased by 3 mm, increased by 4 mm
当然,这样的放大系数只是适合于一般的瓦楞纸箱,如果遇到对摇盖要求很高的纸箱,可以通过函数求出纸箱摇盖的放大系数。另外,上表列出的放大系数不适合于宽度低于20 cm的纸箱。
Of course, this amplification factor is only suitable for general corrugated boxes. If you encounter cartons with high requirements for flap, you can calculate the amplification factor of carton flap through function. In addition, the magnification factors listed in the above table are not suitable for cartons with a width of less than 20 cm.
3.接头尺寸的设计
3. Design of joint size
瓦楞纸箱通过粘合、钉合接头来成型,接头尺的尺寸一般根据瓦楞层数及工厂的工艺水平而定。为保持主箱面(LH面)的印刷面不被破坏,接头一般应与LH面连接。单瓦楞接头尺寸一般为35 mm~40 mm,双瓦楞45 mm~50 mm,三瓦楞为50 mm。
Corrugated boxes are formed by bonding and nailing joints. The size of the joint ruler is generally determined according to the number of corrugated layers and the process level of the factory. In order to keep the printed surface of the main box surface (LH surface) from being damaged, the joint shall generally be connected with the LH surface. The size of single corrugated joint is generally 35 mm ~ 40 mm, double corrugated joint is 45 mm ~ 50 mm, and three corrugated joint is 50 mm.
4.纸箱落料规格的计算
4. Calculation of carton blanking specification
生产的纸箱还是以0201型瓦楞纸箱为主,如下图所示。根据上述所讲,就可以计算出要将一个普通的0201型纸箱投于生产所需要耗费多少材料了。
The cartons produced are mainly 0201 corrugated cartons, as shown in the figure below. According to the above, we can calculate the amount of materials needed to put an ordinary 0201 carton into production.
纸板的长度=2L+2B+纸箱的结舌;
Length of paperboard = 2L + 2B + tongue of carton;
纸板的宽度=H+2倍的纸箱摇盖。
Width of paperboard = H + 2 times of carton shake cover.
根据公式,我们计算出纸箱的落料规格。这里计算出了纸箱的净料规格,在生产时还会修边。为了尽量节省材料,一般修边尺寸不会大于1 cm。靠近结舌的边不需要修边。异型箱落料尺寸根据同样的原理即可算出,只是不同的箱型计算的公式不一样而已。
According to the formula, we calculate the blanking specification of the carton. The net material specification of the carton is calculated here, and the edge will be trimmed during production. In order to save materials as much as possible, the general trimming size will not be greater than 1 cm. The edge near the tongue does not need trimming. The blanking size of special-shaped box can be calculated according to the same principle, but the calculation formulas of different box types are different.
