Problems solved by technology
The present invention aims at the above-mentioned shortcomings existing in the prior art, and makes improvements to overcome the difficulty in inserting pins into corrugated paper samples due to the uneven spacing of corrugated cardboard holes, troublesome disassembly when pins are damaged, and insertion after a period of use. Needle jacks are easy to loose, uneven force affects accuracy and precision, and different corrugated types need to replace templates with different aperture sizes, and many spare parts are more troublesome to use.

Embodiment 1
[0026] Embodiment 1 refers to Figure 1 to Figure 16 As shown, the corrugated paper adhesive strength device of the present invention includes a lower pin fixing base 1, a pressing plate 2, a lower pin 3, a connecting screw 4, a lower support 5, a connecting nut 6, an upper pin 7, a slider 8, an upper Pin fixing base 9, support slider 10, upper support member 11.
[0027] In this embodiment, E corrugated cardboard is selected as the experimental sample to detect the bonding strength.
[0028](1) First take the sample size of 100*25mm; (2) Remove the pin 3 and the upper pin 7 according to the test standard, and the diameter and spacing of the pins are respectively suitable for the height of the corrugated cardboard and the spacing of the corrugated holes match. Since the flute height of E-corrugated cardboard is very small, there are 4 types of sizes for the design of the lower pin 3 and the upper pin 7 (the diameter of the pin is 1mm, 2mm, 3mm and 3.5mm) to choose from, and ...

Abstract
The invention discloses a device for detecting bonding strength of corrugated paper. The device for detecting the bonding strength of the corrugated paper comprises upper and lower parts, wherein thelower part at least comprises a lower thrusting needle fixing base 1, a pressing plate 2, a lower thrusting needle 3, a connecting screw rod 4, a lower supporting piece 5 and a connecting nut 6; and the upper part at least comprises an upper thrusting needle 7, a sliding block 8, an upper thrusting needle fixing base 9, a supporting sliding block 10 and an upper supporting piece 11. According to the device for detecting bonding strength, by using a flexible method that corrugated paper plates are penetrated and inserted firstly by the thrusting needles and then fixed, the flexible method is applied to the detecting of the bonding strength of various types of the corrugated paper plates, the loss of the thrusting needles can be reduced and fine adjustment time is saved, the using range is wide, the disassembly and displacement of the thrusting needles are convenient, and maintenance and using costs are reduced.
Description
technical field [0001] The invention relates to an auxiliary tool for detecting the bonding strength of corrugated cardboard, and more specifically relates to a device for detecting the bonding strength of corrugated cardboard. Background technique [0002] The bonding strength of corrugated cardboard is an important index to detect the physical performance strength of corrugated cardboard, which reflects the bonding fastness between the paper surface of a certain length of corrugated cardboard and the corrugated base paper. Whether the bonding is tight and firm, and whether the strength meets the requirements will directly affect the use effect of corrugated cardboard. If the cardboard is not bonded firmly, the strength of the produced corrugated carton is insufficient, and the layers are prone to peeling off during use, which directly leads to a decrease in the shock resistance and compressive strength of the finished carton, and is prone to damage during stacking and tran...
