Description

Technical Field

[0001] The utility model belongs to the technical field of label testing, and particularly relates to a fixing device for tensile testing of labels. Background Art

[0002] Common labels mainly include self-adhesive labels. Self-adhesive labels are a kind of universal labels, which have the advantages of not requiring glue brushing, paste, water dipping, being pollution-free, saving labeling time, etc. They have a wide range of applications and are convenient and fast. Self-adhesive labels are a composite material with paper, film or other special materials as the fabric, an adhesive coated on the back, and a silicone-coated protective paper as the base paper, and are made into finished labels after processes such as printing and die-cutting.

[0003] In the production of labels, tensile testing operations need to be carried out on them. Conventional testing equipment is a tensile testing device, which is a device for testing and evaluating the tensile strength and durability of labels under force.

[0004] However, when the existing tensile testing device tests label products, the clamping effect on the label products is poor, which easily causes the labels in the test to fall off. Moreover, when fixing the labels, it is also a vertical fixation on one end of the label. Therefore, when the label is under force, the label will still have a detachment problem, thus affecting the normal testing of the label and further affecting the accuracy of the test data.

[0005] Therefore, the fixing structure used in cooperation with the tensile testing device during testing is extremely important. It fixes the self-adhesive label to be detected accurately and stably to complete the next force application test action, etc. The rationality of the design of the fixing structure will directly affect the tensile testing efficiency and testing accuracy of the testing device.

It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present utility model. In addition, the terms "first", "second", "third", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0092] In addition, the terms "horizontal", "vertical", "hanging", etc. do not mean that the components are required to be absolutely horizontal or hanging, but can be slightly inclined. For example, "horizontal" only means that its direction is more horizontal relative to "vertical", and does not mean that the structure must be completely horizontal, but can be slightly inclined.

[0093] In the present utility model, unless otherwise clearly specified and defined, the first feature being above or below the second feature may include the first and second features being in direct contact, or may include the first and second features not being in direct contact but being in contact through additional features therebetween. Moreover, the first feature being above, over, and on the second feature includes the first feature being directly above and obliquely above the second feature, or merely indicating that the first feature has a higher horizontal height than the second feature. The first feature being below, under, and beneath the second feature includes the first feature being directly below and obliquely below the second feature, or merely indicating that the first feature has a lower horizontal height than the second feature.

[0094] Although the description of the present utility model is made in conjunction with the above specific embodiments, it is obvious that those skilled in the art can make many substitutions, modifications, and changes based on the above content. Therefore, all such substitutions, improvements, and changes are included within the spirit and scope of the appended claims.
