Problems solved by technology

The needle-shaped accessories have a fixed width, and the regulations in the national standard corresponding to the width of various flute-type corrugated cardboard are range values, which leads to the need for needle-shaped accessories that cannot meet the needs of the experiment, and according to GB / T 6548-2011 According to the requirements in Table 1 of "Determination of Strength", each sample needs to be tested for each adhesive layer at least 5 times, resulting in at least 90 pin insertions for single corrugated cardboard, at least 180 times for double corrugated cardboard, and more than 270 times for triple corrugated cardboard.
This results in the insertion of a single needle taking too long

Embodiment Construction

[0022] Combine below Figure 1 to Figure 6 Specific embodiments of the present invention will be described.

[0023] figure 1 and figure 2 The overall structural form of the layout of the pin header is shown. The experimental pin header includes: a non-closed chain 2 connected by fourteen chain links 21, seven pins 1 and eight sliding shafts 22 as a non-closed chain The hinge shafts of 2 are alternately interspersed between the chain links 21, and the hinge holes on the outside of the chain links 21 at both ends of the non-closed chain 2 are sliding shafts 22; wherein, the sliding shafts 22 can only move in the length direction of the chain 2 to adjust The distance S between each pin 1 and the number of pins 1 can be increased or decreased according to actual detection requirements. This embodiment is described with the most conventional distance between seven pins 1 .

Abstract

The invention provides a pin header for a corrugated board bonding strength experiment. The pin header comprises a non-closed chain formed by connecting 2N chain links, N contact pins and N + 1 sliding shafts which are used as hinged shafts of the non-closed chain and alternately penetrate among the chain links, and the sliding shafts are arranged in hinge holes in the outer sides of the chain links at the two ends of the non-closed chain. The sliding shafts can only move in the length direction of the chain so as to adjust the distance S between the contact pins.

Description

technical field [0001] The invention relates to a pin header for bonding strength experiments, in particular to a pin header for corrugated cardboard bonding strength experiments. Background technique [0002] The bonding strength of corrugated cardboard reflects the tightness of the bonding between the corrugated cardboard sheets, which directly affects the compressive strength of the carton. When the adhesive strength of corrugated cardboard is unqualified, the probability of edge compressive strength and compressive strength of corrugated cardboard is unqualified is higher. It can be seen that adhesive strength is an important technical index that cannot be ignored. [0003] The original experimental equipment for testing the adhesive strength of corrugated cardboard is to use a fixed needle-shaped accessory or a single pressure needle to insert the experiment. The needle-shaped accessories have a fixed width, and the regulations in the national standard corresponding to...
