Description

Technical Field

[0001] The utility model belongs to the technical field of printing thickener detection equipment, in particular to a testing device for printing thickener. Background Art

[0002] Printing thickener is the most commonly used thickener in the printing industry. In printing, two main materials, glue and color paste, are used. Because the consistency will be reduced under high shear force, thickeners are needed to increase the consistency of the printing material. At this time, printing thickeners are needed. Printing thickeners need to be tested before use. The most important thing is to test the concentration and pH value of printing thickeners. The current testing device has the following disadvantages in testing the concentration and pH value of printing thickeners:

[0003] 1. When testing the concentration of printing thickeners, densitometers are often used. However, the current electronic densitometers are not only expensive, but also corroded and damaged by the printing thickeners during long-term use, making the concentration testing of printing thickeners by electronic densitometers less economical.

[0004] 2. At present, the pH of printing thickeners is generally tested by pH testers. When using pH testers, testers are required to put the detection probe connected with a wire into the container containing printing thickeners, and pull it out after the test is completed. This can easily cause the testing personnel's hands to be stuck with printing thickeners and dirty their hands.

[0005] Therefore, it is necessary to improve the prior art to solve the above-mentioned technical problems. Utility Model Content

[0006] The utility model aims to provide a testing device for printing thickeners. When in use, the greater the concentration of the printing thickener in the sample frame, the greater the weight of the sample frame, the greater the downward displacement of the sliding inner frame, and the greater the scale number pointed to by the indicator block. The test personnel can quickly know the concentration of the printing thickener in the sample frame by observing the scale number pointed to by the indicator block, thereby solving the problem that the existing use of electronic densitometers for testing is not only expensive but also will be corroded and destroyed by the printing thickener during long-term use.

[0007] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

DETAILED DESCRIPTION

[0025] 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.

[0026] See also Figure 1-4As shown, the utility model is a testing device for printing thickeners, comprising a fixed outer frame 100, springs 110 are fixedly installed on the lower end of the inner wall of the fixed outer frame 100 in a circumferential arrangement, a sliding inner frame 200 is fixedly installed on the upper end of the outer walls of all the springs 110, a sample frame 300 is placed inside the sliding inner frame 200, a strip opening groove 400 is opened at the front end of the side wall of the fixed outer frame 100, a connecting rod 410 is fixedly installed at the front end of the side wall of the sliding inner frame 200, the front end of the outer wall of the connecting rod 410 passes through the strip opening groove 400 and an indicating block 420 is fixedly installed, a mounting plate 500 is fixedly installed at the front end of the outer wall of the fixed outer frame 100 and located on the side of the strip opening groove 400, a scale plate 510 is fixedly installed on the front end of the outer wall of the mounting plate 500, the sample frame 300 containing a unit volume of printing thickener is put into the sliding inner frame 200, and the sliding inner frame 200 will be subjected to downward movement. The pressure moves downward and squeezes the compression spring 110. If the concentration of the printing thickener in the sample frame 300 is greater, the weight of the sample frame 300 is greater, the pressure on the sliding inner frame 200 is greater, and the displacement of the sliding inner frame 200 moving downward is greater. The downward movement of the sliding inner frame 200 will drive the indicating block 420 to move downward, pointing to different scales on the scale plate 510. The scales on the scale plate 510 increase from top to bottom. The greater the concentration of the printing thickener, the larger the scale number pointed to by the indicating block 420. T-shaped grooves 210 are symmetrically opened on the left and right sides of the outer wall of the sliding inner frame 200, and T-shaped sliders 220 are symmetrically fixedly installed on the left and right sides of the inner wall of the fixed outer frame 100. The T-shaped slider 220 is slidably connected to the T-shaped groove 210. The slidable connection between the T-shaped slider 220 and the T-shaped groove 210 improves the stability of the connection between the sliding inner frame 200 and the fixed outer frame 100.

[0027] Among them Figure 4 As shown, an annular height plate 310 is fixedly installed on the inner wall of the sample frame 300, and a handle bar 320 is symmetrically fixedly installed on the upper end of the outer wall of the annular height plate 310. The annular height plate 310 is used to conveniently limit the amount of printing thickener poured into the sample frame 300, so that the inspector can pour a unit volume of printing thickener into the sample frame 300. At the same time, the handle bar 320 can facilitate the inspector to move the sample frame 300.

[0028] Among them Figure 1-2As shown, a bottom plate 600 is fixedly installed at the lower end of the outer wall of the fixed outer frame 100, an electric telescopic rod 620 is fixedly installed at the upper end of the outer wall of the bottom plate 600 and located on the right side of the fixed outer frame 100, a connecting plate 630 is fixedly installed at the upper end of the outer wall of the electric telescopic rod 620, and a through hole 1 631 and a through hole 2 632 are opened, a pH detector 610 is fixedly installed at the upper end of the outer wall of the bottom plate 600, and a connecting wire 611 is fixedly installed on the pH detector 610, and the upper end of the outer wall of the connecting wire 611 penetrates from the through hole 1 631 to the top of the connecting plate 630 and exits from the through hole The second through hole 632 passes through the bottom of the connecting plate 630, and the free end of the connecting wire 611 is fixedly installed with a detection probe 612. After the electric telescopic rod 620 is contracted, it can drive the connecting plate 630 to move downward, so that the connecting wire 611 slides in the through hole 1 631 and the through hole 2 632, and the position of the detection probe 612 is lowered, and enters into the printing thickener in the sample frame 300 to detect the pH value of the printing thickener in the sample frame 300. After the detection is completed, the detection probe 612 can be lifted up by simply raising the connecting plate 630 again.

[0029] Among them Figure 1-2 As shown, a mounting frame 700 is fixedly installed at the upper end of the outer wall of the connecting plate 630 and between the through hole 1 631 and the through hole 2 632. A rotating wheel 710 is rotatably connected inside the mounting frame 700. The connecting wire 611 is slidably connected to the rotating wheel 710. The sliding connection between the connecting wire 611 and the rotating wheel 710 reduces the friction force on the connecting wire 611.

[0030] A specific application of this embodiment is as follows: when in use, the inspector first pours the printing thickener into the height position of the annular height plate 310 in the sample frame 300, and then puts the sample frame 300 into the sliding inner frame 200. At this time, the sliding inner frame 200 will be subjected to downward pressure and move downward and squeeze the compression spring 110. If the concentration of the printing thickener in the sample frame 300 is greater, the weight of the sample frame 300 is greater, the pressure on the sliding inner frame 200 is greater, and the displacement of the sliding inner frame 200 moving downward is greater. The downward movement of the sliding inner frame 200 will drive the indicator block 420 to move downward, pointing to different scales on the scale plate 510. The scales on the scale plate 510 increase from top to bottom, so the printing thickener in the sample frame 300 is greater than the printing thickener in the sample frame 300. The greater the concentration of the thickener, the larger the scale number pointed to by the indicator block 420. The inspector can quickly know the concentration of the printing thickener in the sample frame 300 by observing the scale number pointed to by the indicator block 420. At the same time, when performing pH value detection, the electric telescopic rod 620 can contract to drive the connecting plate 630 to move downward, so that the connecting wire 611 slides in the through hole 1 631 and the through hole 2 632, so that the position of the detection probe 612 is lowered and entered into the printing thickener in the sample frame 300, and the pH value of the printing thickener in the sample frame 300 is detected. After the detection is completed, the detection probe 612 can be lifted up by simply raising the connecting plate 630 again, and the inspector does not need to manually lift the detection probe 612.

[0031] The above are only preferred embodiments of the present invention and do not limit the present invention. Any modification to the technical solutions recorded in the aforementioned embodiments and any equivalent replacement of some of the technical features therein, any modification, equivalent replacement, and improvement made are all within the protection scope of the present invention.
