Description

Technical Field

[0001] The utility model relates to the technical field of offset printing ink insulation, in particular to a thermal insulation device for environmentally friendly offset printing ink. Background Art

[0002] Offset ink is a commonly used fountain solution in offset printing. In offset printing in northern regions, due to the low temperature in winter, the offset ink generally has problems such as high hardness and poor fluidity during the preparation process, which is inconvenient for workers to operate. Therefore, the offset ink is often stably heated through a heat preservation device to facilitate the staff to use it for printing.

[0003] When the existing insulation device insulates the offset ink inside, a heating structure installed outside the insulation device is used to heat the inside of the device to ensure the fluidity of the offset ink. However, the internal offset ink is heated unevenly and causes agglomeration, which will cause the extraction structure to be unable to extract all the offset ink inside the device. At the same time, offset ink with low heating effect enters the extraction structure and is prone to clogging inside it. Therefore, an insulation device for environmentally friendly offset ink is proposed. Utility Model Content

[0004] In view of the fact that the above-mentioned existing internal offset ink has the phenomenon of agglomeration due to uneven heating, which will cause the extraction structure to be unable to extract all the offset ink inside the device, and the offset ink with low heating effect will easily get stuck inside the extraction structure, the present utility model is proposed.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a heat preservation device for environmentally friendly offset printing ink, comprising a heating barrel and a heat preservation barrel, wherein the heat preservation barrel is installed inside the heating barrel, a driving shaft is rotatably plugged into the upper surface of the heat preservation barrel, an inner cavity prism shaft is slidably plugged into the inner part of the driving shaft, one end of the inner cavity prism shaft located inside the heat preservation barrel is fixedly sleeved with an inner cavity plate, a heating plate is installed on the bottom surface of the inner cavity plate, floating cavity balls are fixedly installed on the front and back sides of the inner cavity plate, absorption holes are provided on the bottom surface and the front and back sides of the inner cavity plate, a power extraction tube is installed on the right side surface of the heating barrel, a connecting tube is slidably plugged into the upper end of the power extraction tube, and the other end of the connecting tube is fixedly plugged into the upper end of the inner cavity prism shaft, a power structure is installed on the upper surface of the heat preservation barrel, the power structure is connected to the driving shaft, and an absorption groove is provided at the lower end of the inner cavity prism shaft.

[0006] Preferably, the power structure includes a motor, a driving gear and a driven gear, the driven gear is fixedly sleeved on the outer surface of the driving shaft, the driving gear is meshed with the driven gear, the driving gear is fixedly connected to the output end of the motor, and the motor is installed on the upper surface of the insulation barrel.

[0007] Preferably, the outer ring surface of the driving gear is provided with a plurality of notches, and the plurality of notches are distributed in an array around the axis of the driving gear.

[0008] Preferably, the inner cavity plates are distributed in an S-shape, and the center of the inner cavity plates is coaxially arranged with the inner cavity prism axis.

[0009] Preferably, the two floating cavity balls are distributed in a circular array along the axis of the inner cavity prism axis, and the lower ends of the floating cavity balls are located above the absorption holes.

[0010] Preferably, the outer surface of the inner cavity prism shaft is a prismatic structure, and the inner annular surface of the driving shaft matches the outer surface of the inner cavity prism shaft.

[0011] Preferably, the bottom surface of the inner cavity prism axis contacts the inner bottom wall of the inner cavity plate, and a plurality of absorption grooves are provided and distributed in a circular array around the axis of the inner cavity prism axis.

[0012] Preferably, a plurality of heating rods are provided on both sides of the inner cavity plate, and the lower ends of the heating rods are mounted on the surface of the heating plate.

[0013] Beneficial effects of the utility model:

[0014] 1. By setting the heating plate, the inner cavity plate and the absorption hole, when the material is drawn from the device, the heating plate heats the offset ink around the absorption hole, and heats the offset ink at the drawing location to a sufficient temperature to ensure the fluidity of the offset ink entering the inner cavity plate. At the same time, the power structure drives the inner cavity prism shaft, the inner cavity plate and the heating plate to rotate through the driving shaft, so that the circumferential surface in the insulation barrel can be evenly heated and drawn.

[0015] 2. By setting a float ball, the float ball floats on the surface of the offset ink liquid, so that the heating plate and the inner cavity plate can start to draw materials from the upper layer of the liquid.
