Description

Technical Field

[0001] The present invention relates to the technical field of kraft paper detection, and in particular to a kraft paper performance detection device and a use method thereof. Background Art

[0002] In the prior art, after the production of kraft paper is completed, its performance needs to be tested, and there are many test items. For example, a Chinese patent (application number: 202321318175.8) discloses a kraft paper waterproof performance testing device. The temperature of the water in the immersion bucket is changed by a thermostat to observe the waterproof performance of kraft paper under different temperature environments, thereby increasing the influencing factors during the test. At the same time, the kraft paper can be pressed during the test to obtain the waterproof performance of the kraft paper in a taut state, making the test results more universal, and solving the problem that the traditional kraft paper waterproof performance testing method has too single value and cannot achieve the purpose of comprehensive testing of the kraft paper waterproof performance.

[0003] For example, a Chinese patent (application number: 202321318179.6) discloses a kraft paper compression resistance testing device. The longitudinal position of the clamping arm is adjusted by adjusting the position of the longitudinal adjustment plate through the longitudinal push rod. The position of the transverse adjustment plate is adjusted by the transverse push rod, thereby adjusting the transverse position of the clamping arm. After the clamping arm clamps the kraft paper, the position of the clamping arm can be adjusted according to actual needs. The kraft paper can be tensioned and flattened by adjusting the position of the clamping arm, replacing manual flattening of the kraft paper, which is convenient and quick to operate.

[0004] However, when testing kraft paper, the above two patents only test a few items, and do not test the light transmittance, scratch resistance and fire resistance of the kraft paper. Therefore, improvements are needed. Summary of the invention

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] like Figure 1-5 As shown, the present invention provides a kraft paper performance testing device, including a testing table 1, a plurality of table legs 2 arranged in a rectangular array are fixed at the bottom of the testing table 1, a rectangular placement slot 1-1 is provided on the top of the testing table 1, the placement slot 1-1 is used to place kraft paper M, a rectangular detection slot 1-2 is provided at the bottom of the placement slot 1-1, the slot opening of the detection slot 1-2 is smaller than the bottom of the placement slot 1-1, a locking mechanism for fixing the kraft paper M is provided in the placement slot 1-1, a detection mechanism is slidably installed on the bottom of the testing table 1, and the detection mechanism can slide along the length direction of the detection slot 1-2.

[0024] In order to lock the kraft paper M, the locking mechanism includes a pressure ring 3 pressed on the kraft paper M, the pressure ring 3 matches the placement groove 1-1, and the two ends of the pressure ring 3 are detachably installed at the two ends of the placement groove 1-1. Ear plates 4 are fixed at both ends of the pressure ring 3, and card slots 1-3 matching the ear plates 4 are opened at both ends of the placement groove 1-1. Vertical bolts are threadedly installed on the ear plates 4, and the lower end of the bolt is threadedly installed at the bottom of the card slot 1-3.

[0025] Specifically in the present invention, the detection mechanism includes two symmetrically arranged mounting plates 5, the upper ends of the two mounting plates 5 are slidably mounted on the bottom of the detection platform 1, a mounting rod 6 is fixed between the two mounting plates 5, and a detection structure is installed on the mounting rod 6. The detection structure includes a ring 9 rotatably mounted on the mounting rod 6, and the angle of the ring 9 can be adjusted on the mounting rod 6. The outer circumferential surface of the ring 9 is fixed with a scratch needle 10, a lighting lamp 11, and a lighter 12 arranged in a circular array.

[0026] In order to realize the sliding of the detection structure, two symmetrically arranged sliding rods 7 are fixed to the bottom of the detection platform 1. The cross section of the sliding rod 7 is "convex". A sliding sleeve 8 matching the sliding rod 7 is fixed to the upper end of the mounting rod 6.

[0027] In order to lock the detection structure, the mounting rod 6 is a threaded rod, on which a nut 13 is threadedly mounted, and two nuts 13 are clamped on both sides of the ring 9 .

[0028] The present invention also discloses a method for using the above-mentioned hemodialysis device, comprising the following steps:

[0029] Step 1: Cut the kraft paper M into strips of the same shape as the placement slot 1-1, place them at the bottom of the placement slot 1-1, and then place the pressure ring 3 at the bottom of the placement slot 1-1. At this time, the ear plate 4 is stuck in the slot 1-3, and the bolt is screwed on the ear plate 4 until the lower end of the bolt is threadedly installed at the bottom of the slot 1-3, so as to fix the pressure ring 3 in the installation slot, thereby achieving the compression of the kraft paper M;

[0030] Step 2: First, test the light transmittance of the kraft paper M, rotate the two nuts 13 in opposite directions, and stop tightening the ring 9. Then, the ring 9 can be rotated to drive the illuminating lamp 11 to rotate. Here, the illuminating lamp 11 can be a flashlight with a battery. Then, the nuts 13 can be rotated relatively to clamp the two nuts 13 on both sides of the ring 9 to lock the ring 9, and then the illuminating lamp 11 can be locked. Then, the illuminating lamp 11 can be pushed to move, and the mounting plate 5 and the sliding sleeve 8 can slide along the sliding rod 7 to test the light transmittance of the entire kraft paper M.

[0031] Step 3: Secondly, the scratch resistance of the kraft paper M is tested. According to the above operation, the two nuts 13 are rotated in opposite directions without tightening the ring 9, so that the scratch needle 10 can be rotated upward. During the rotation process, the tip of the scratch needle 10 will scratch the kraft paper M until the kraft paper M is broken. The angle of the upward rotation of the scratch needle 10 is measured with a protractor to obtain the scratch resistance of the kraft paper M. Here, after the tip of the scratch needle 10 contacts the kraft paper M, the two nuts 13 can also be rotated relatively to clamp them on both sides of the ring 9, so that the detection structure can be pushed to make the sliding sleeve 8 slide along the sliding rod 7, so that the scratch needle 10 moves along the kraft paper M, scratch the kraft paper M, and judge the scratch resistance of the kraft paper M.

[0032] Step 4, then the fire resistance of the kraft paper M is tested. According to the above operation, the nuts 13 are rotated in opposite directions, the ignition gun 12 is rotated upward, the ignition gun 12 is started, and the height of the flame of the ignition gun 12 is changed to burn the kraft paper M. The fire resistance of the kraft paper M can be tested according to the height of the flame of the ignition gun 12 and the time for the kraft paper M to burn through;

[0033] Step 5, unscrew the bolts from the ear plate 4, so that the pressure ring 3 can be removed from the placement groove 1-1, and then the scrapped kraft paper M can be cleaned up.

[0034] Finally, the most important contribution of the present invention is that the scratch needle 10, the lighting lamp 11, and the lighter 12 in the detection structure can be rotated through the ring 9, so that one of them can detect one of the properties of the kraft paper M, thereby improving practicality.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
