Description

Technical Field

[0001] The utility model relates to the technical field of ink detection, in particular to an ink back adhesion detector. Background Art

[0002] Ink is an important material used for printing. It prints or sprays patterns and texts on substrates. In the existing testing process, only the stability of ink quality at normal temperature and pressure is generally tested. When the ink arrives at the printing factory for printing, the printed products cannot meet the constant temperature and humidity conditions in the customer's workshop and warehouse. The temperature and humidity change greatly, and the rolls and stacks are placed after printing for an uncertain period of time, which greatly causes the instability of product quality. It is very easy for the printed surface of the paper to stick to the back of the previous paper, which is called back sticking. After checking, the utility model patent with publication number CN206848146 U records a device for detecting the anti-sticking performance of water-based varnish, which includes a base, a cylindrical pillar, a load-bearing pillar and a table top. A hydraulic cylinder is installed at the center of the support box opposite to the load-bearing head, and an electric heating pressure head is installed at the lower end of the hydraulic cylinder piston rod, and an upper thermocouple sensing head is installed at the lower end of the electric heating pressure head. An electric heating load-bearing head is installed at the upper end of the load-bearing pillar, and a lower thermocouple sensing head is installed at the upper end of the electric heating load-bearing head. The device can perform sticking detection at different pressures and temperatures. The device provides pressure through a hydraulic box and a hydraulic rod, and provides a heat source through an electric heating pipe. However, this method is not only costly but also difficult to control constant temperature and pressure. Therefore, in response to this technical problem, the present application provides an ink sticking detection instrument. Utility Model Content

In this way, compared with the hydraulic cylinder, the adjustment is more convenient, the constant pressure is more stable and the cost is lower. The upper pressing block 11 and the lower supporting block 10 are connected by a water supply hose 12, so that hot water can be injected into the upper pressing block 11 and the lower supporting block 10. The upper pressing block 11 is connected to the water pump 5 through a water inlet hose 13, and the water inlet port of the water pump 5 is connected to the constant temperature water pot 2. The lower supporting block 10 is connected to the constant temperature water pot 2 through a drainage hose 14, so as to achieve the effect of circulating water inlet.

[0021] Embodiment 2:

[0022] On the basis of the above embodiment, another embodiment of the utility model is that it also includes a base plate 1, and the constant temperature water pot 2, water pump 5, side plate 6 and sensor mounting seat 7 are all arranged on the base plate 1.
