Everyone usually puts things in a cardboard box if they send things, so that they can have a protection for such things. Many businesses now use a type of corrugated box. Do you know how to calculate the size of this corrugated box ? Everyone may not be familiar with this kind of carton, or let Xiaobian introduce it to everyone. Corrugated box size calculation formula: The determining factors of the inner diameter are mainly the maximum outer diameter of the inner casing, the tolerance coefficient determined according to the form of the inner body, the arrangement of the contents, the relevant dimensions of the inner partition and the cushioning member. The calculation of the inner diameter size can be obtained by the following formula: Xi = Xmaxnx + d(nx-1) + k' + T. Where, Xi is the inner diameter of the carton; Xmax is the maximum outer diameter of the individual contents; d is the number of the contents of the contents in the carton; k' is the compensation for the inner diameter of the carton; T is the total of the spacer or cushion thickness. The length units are all mm. Need to meet the outer diameter size of Xi > interior goods. The correction factor and tolerance factor can be found in the table. The manufacturing dimensions are calculated as: X = Xi + t + k where, for corrugated board manufacturing dimensions, cardboard thickness, is the correction factor. The size of the value is related to the specific size of the carton. In actual use, due to the rebound of the inner flap, it has a tendency to tilt outward. In order to reduce the increase in headroom caused by this reason, the value in the height direction should be 2t. The outer diameter dimension is calculated as: X0 = X + K where X0 is the outer diameter dimension and K is the correction factor. The manufacturing dimensions of the corrugated box outer flap are also a key part to be aware of. In the box type of the corrugated box outside the flap, such as 0201, 0204, 0207, etc., the theoretical value of the width of the flap width should be one-half of the manufacturing size of the box width. However, due to the rebound effect of the inner flap, the lid is not horizontal after being closed, but is slightly inclined, and the outer flap must have a certain gap at the joint. Therefore, the width of the outer flap is not half the width, but is slightly longer, so an amplification factor is added to the actual production. The magnification factor can be calculated by a trigonometric function. However, due to the plasticity of the carton itself, and for ease of calculation, most companies calculate a fixed magnification factor based on the thickness of the cardboard. As shown in the following table: Cardboard thickness 3 mm or less 3 mm~5 mm 5 mm~8 mm 8 mm~12 mm Magnification factor does not increase by 1 mm, enlarges by 3 mm, increases by 4 mm Of course, such a magnification factor is only suitable for a general corrugated box. If a carton that requires a high amount of the flap is encountered, the magnification factor of the carton cover can be found by a function. In addition, the magnification factors listed in the above table are not suitable for cartons with a width of less than 20 cm. Everyone seems to believe that the above content has a certain understanding of the corrugment box size calculation formula, the next time we send things out, we can measure the most suitable carton size.
For the working population, sedentary is a common normal, all kinds of lumbar disease, cervical spondylosis "into" people's body, bring a lot of trouble to people. Sitting for more than 2 hours without standing up and changing sitting posture is considered as sedentary.
Stand up desk is of great help to healthy office, and modern people's demand for health is also growing. Fully stand in the perspective of users to think about the problem, and the lifting desk with freely adjustable height can bring users a new experience of healthy office.
stand up desk can adjust the height of the desk according to its own needs, so that it can work in the most comfortable state.
