[0019] Compared with the prior art, the viscosity control device provided by the present application has the following technical advantages:

The open end of the containing barrel is provided with a support member, and the dispersion mechanism and the viscosity detection mechanism are fixedly arranged on the support member and extend into the containing barrel. The control assembly is in signal connection with the viscosity detection mechanism and the dispersion mechanism. Since the fluid contained in the containing barrel is solvent-free ink, which is a non-Newtonian fluid, according to the characteristics of the non-Newtonian fluid, shear force / shear rate≠constant value, that is, the viscosity is a variable.

[0037] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The following examples and features in the examples can be combined with each other without conflict.

[0038] The viscosity control device provided in the embodiment includes a containing barrel 100 and a dispersion mechanism 200, a viscosity detection mechanism 300 and a control assembly;

[0039] The opening end of the containing barrel 100 is provided with a support 110, and the dispersion mechanism 200 and the viscosity detection mechanism 300 are fixedly arranged on the support 110 and extend into the containing barrel 100, and the control assembly is signal connected with the viscosity detection mechanism 300 and the dispersion mechanism 200 respectively.

[0040] Specific combination Figure 1 and Figure 2As shown, the support 110 is provided in a cover shape and covers the open end of the containing barrel 100, and the dispersion mechanism 200 is fixedly installed on the support 110 and extends into the containing barrel 100 to contact the fluid contained in the containing barrel 100. In this embodiment, the control assembly includes two frequency converters, a PLC control system and a viscosity meter voltage signal module. The two frequency converters control the dispersion mechanism 200 and the viscosity detection mechanism 300 respectively, the viscosity meter voltage signal module is signal connected with the viscosity detection mechanism 300, and the two frequency converters and the viscosity meter voltage signal module are connected with the PLC control system. In the working process of the viscosity control device, when the viscosity detection mechanism 300 detects the viscosity, the viscosity value is converted into a voltage signal, the viscosity meter voltage signal module transmits the captured signal to the PLC control system, the PLC control system compares the range of the input voltage signal with the set standard value, transmits the result to the two frequency converters, and then controls the dispersion mechanism 200 and the viscosity detection mechanism 300 through the two frequency converters, so as to control the viscosity of the ink by changing the corresponding operating state of the dispersion mechanism 200 and the viscosity detection mechanism 300. In this process, the situation that the viscosity of the solvent-free ink fluctuates too much can be avoided, the difficulty of viscosity control is reduced, and the waste of ink can be reduced. At the same time, the control assembly cooperates with the viscosity detection mechanism 300 and the dispersion mechanism 200 to realize automatic adjustment of the viscosity of the solvent-free ink, and further reduces the control difficulty of the viscosity of the solvent-free ink. In addition, the support 110 covers the open end of the containing barrel 100, so that foreign matters can be prevented from entering the containing barrel 100.

[0041] In the optional technical solution of this embodiment, the dispersion mechanism 200 includes a dispersion assembly 210 and a dispersion driving member 220, the dispersion driving member 220 is fixedly arranged on the support 110 and is in transmission connection with the dispersion assembly 210, and the dispersion assembly 210 is located in the containing barrel 100.

[0042] Specific combination Figure 1 As shown, the dispersion assembly 210 is located in the containing barrel 100 and is in transmission connection with the dispersion driving member 220. When it is necessary to change the viscosity of the solvent-free ink in the containing barrel 100, the dispersion driving member 220 is started, and the dispersion driving member 220 drives the dispersion assembly 210 to move. In this process, the dispersion assembly 210 shears the solvent-free ink, and according to the target viscosity, the working time and shearing speed of the dispersion driving member 220 are changed, so as to change the viscosity of the solvent-free ink. In this process, the situation that the viscosity of the solvent-free ink fluctuates too much can be avoided, the difficulty of viscosity control is reduced, and the waste of ink can be reduced.

[0043] In the optional technical scheme of the embodiment, the dispersion driving member 220 is arranged as a driving motor, and the dispersion assembly 210 comprises a dispersion disc 211 and at least one dispersion sawtooth 212.

[0044] The dispersion disc 211 is in transmission connection with the motor shaft of the driving motor, and the dispersion sawtooth 212 is fixedly arranged on the dispersion disc 211.

[0045] Specifically Figure 1 As shown in the figure, the dispersion disc 211 is arranged as a plate and is fixedly connected with the motor shaft of the motor, and the dispersion sawtooth 212 is fixedly arranged on the dispersion disc 211. In the embodiment, the dispersion disc 211 is arranged as a circular plate, and the diameter of the dispersion disc 211 is arranged as 1 / 3 of the inner diameter of the containing barrel 100, and the distance from the dispersion disc 211 to the inner side of the bottom wall of the containing barrel 100 is arranged as ≤1 / 2 of the diameter of the dispersion disc 211. In this way, in the viscosity adjustment process, the motor shaft drives the dispersion disc 211 to rotate, and the dispersion disc 211 and the dispersion sawtooth 212 cooperate with each other to improve the shearing effect on the solvent-free ink, and according to the target viscosity, the working time and shearing speed of the driving motor are changed to change the viscosity of the solvent-free ink.

[0046] In the optional technical scheme of the embodiment, the dispersion sawtooth 212 is arranged as a plurality of dispersion sawteeth 212, the plurality of dispersion sawteeth 212 are divided into two groups, and the two groups of dispersion sawteeth 212 are fixedly arranged on the two end faces of the dispersion disc 211 and are arranged away from the central axis of the dispersion disc 211.

[0047] Specifically Figure 1 As shown in the figure, in the viscosity adjustment process, when the motor shaft drives the dispersion disc 211 to rotate, centrifugal force is generated on the motor shaft and the dispersion disc 211, and the solvent-free ink moves away from the axis of the motor shaft. Therefore, when the dispersion sawtooth 212 is arranged, the dispersion sawtooth 212 is arranged away from the central axis of the dispersion disc 211, and the plurality of dispersion sawteeth 212 are divided into two groups, and the two groups of dispersion sawteeth 212 are fixedly arranged on the two end faces of the dispersion disc 211. The two groups of dispersion sawteeth 212 cooperate with the dispersion disc 211 to further improve the shearing effect on the solvent-free ink, thereby reducing the difficulty of viscosity adjustment.

[0048] In the optional technical scheme of the embodiment, the viscosity detection mechanism 300 comprises a detection driving member 310, a feeding pump 320 and a viscosity detector 330.

[0049] The detection driving member 310 and the viscosity detector 330 are both fixedly arranged on the support member 110, the feeding pump 320 is in transmission connection with the detection driving member 310 and is located in the containing barrel 100, and the feeding pump 320 is in communication with the viscosity detector 330.

[0050] Specifically Figure 1 and Figure 2As shown, the detection driving member 310 is arranged as a driving motor, and the driving motor and the viscosity detector 330 are fixedly arranged on the support member 110. The feeding pump 320 is in transmission connection with the driving motor, and is located in the containing barrel 100 and in communication with the viscosity detector 330. When the voltage signal interval value K fed back by the viscosity detector 330 is greater than P0, the PLC control system sends a signal to the two frequency conversion controllers, and the two frequency conversion controllers control the motor frequency of the two driving motors to increase, so as to increase the stirring rate, the frequency of the feeding pump 320 is increased to improve the ink liquidity, and the effect of reducing the ink viscosity is achieved. When K is less than P0, the PLC control system sends a signal to the two frequency conversion controllers, and the two frequency conversion controllers control the motor frequency of the two driving motors to decrease, so as to decrease the stirring rate, the flow rate of the feeding pump 320 is decreased to reduce the ink liquidity, and the effect of restoring the ink viscosity is achieved. When the K signal value is in the P0 interval, the two driving motors are normally operated at the standard frequency value set by the corresponding frequency conversion control. In addition, in order to ensure the normal operation of the circulation system, the upper limit value and the lower limit value in the motor frequency adjustment process are set in the two frequency conversion controllers.

[0051] In the optional technical scheme of the embodiment, the viscosity control device further comprises a first pipeline 500 and a second pipeline 600, and one end of each of the first pipeline 500 and the second pipeline 600 is in communication with the viscosity detector 330, and the other end of each of the first pipeline 500 and the second pipeline 600 is in communication with the containing barrel 100.

[0052] Specific combination Figure 1 As shown, one end of the first pipeline 500 is in communication with the side wall of the viscosity detector 330, and the other end of the first pipeline 500 is in communication with the containing barrel 100. One end of the second pipeline 600 is in communication with the bottom wall of the viscosity detector 330, and the other end of the second pipeline 600 is in communication with the containing barrel 100. The communication points of the first pipeline 500 and the second pipeline 600 with the containing barrel 100 are arranged close to the open end of the containing barrel 100. In this way, the circulation of the solvent-free ink in the viscosity control device can be realized, and the control difficulty of the viscosity of the solvent-free ink can be further reduced in cooperation with the dispersion mechanism 200. Moreover, since the communication points of the first pipeline 500 and the second pipeline 600 with the containing barrel 100 are arranged close to the open end of the containing barrel 100, the solvent-free ink in the containing barrel 100 can be prevented from flowing back to the viscosity detector 330 through the first pipeline 500 and the second pipeline 600, and the use experience of the viscosity control device is improved. In addition, the above arrangement can realize the following effects. On the one hand, the detected solvent-free ink can be circulated into the containing barrel 100, and the waste amount of the solvent-free ink can be reduced. On the other hand, the solvent-free ink can be prevented from being taken out of the containing barrel 100 for detection, and the accuracy of the viscosity detection can be improved. Thirdly, the viscosity of the solvent-free ink in the containing barrel 100 can be monitored and adjusted automatically, the inconvenience of manual material taking and measuring can be reduced, and the labor cost can be saved.

[0053] In the optional technical solution of the embodiment, the second pipeline 600 is provided with a regulating valve 610.

[0054] Specific combination Figure 1 As shown, the regulating valve 610 is used to change the circulating amount of the solvent-free ink in the viscosity control device. Specifically, when the regulating valve 610 is closed, all the solvent-free ink reaching the viscosity detector 330 passes through the first pipeline 500 again to reach the containing barrel 100, that is, all the solvent-free ink reaching the viscosity detector 330 participates in the circulation; when the regulating valve 610 is fully opened, all the solvent-free ink reaching the viscosity detector 330 passes through the second pipeline 600 to reach the containing barrel 100, that is, all the solvent-free ink reaching the viscosity detector 330 does not participate in the circulation. In the whole process, by changing the opening amount of the regulating valve 610, the circulating amount of the solvent-free ink in the viscosity control device is changed, and the control difficulty of the viscosity of the solvent-free ink is further reduced in cooperation with the dispersion mechanism 200.

[0055] In the optional technical solution of the embodiment, the viscosity control device further comprises a trough 400, and one end of the first pipeline 500 away from the viscosity detector 330 is communicated with the containing barrel 100 through the trough 400.

[0056] Specific combination Figure 1 As shown, one end of the first pipeline 500 is communicated with the viscosity detector 330, and the other end is communicated with the trough 400, the trough 400 is communicated with the containing barrel 100 through a communication pipeline, and the communication point of the trough 400 and the containing barrel 100 is arranged close to the open end of the containing barrel 100. In this way, on the one hand, the solvent-free ink reaching the containing barrel 100 through the viscosity detector 330 has a certain buffering effect, avoiding the solvent-free ink directly rushing into the containing barrel 100; on the other hand, it is convenient for the operator to supplement the solvent-free ink in the containing barrel 100 through the trough 400; and thirdly, the communication point of the trough 400 and the containing barrel 100 is arranged close to the open end of the containing barrel 100, which can avoid the situation that the solvent-free ink in the containing barrel 100 flows back to the trough 400 through the communication pipeline.

[0057] In the optional technical solution of the embodiment, the side wall of the containing barrel 100 is provided with a heat preservation cavity, and a heat preservation structure 700 is arranged in the heat preservation cavity.

[0058] Specific combination Figure 1As shown, the side wall and the bottom wall of the containing barrel 100 are provided with cavities, and the cavities are provided with heat preservation structures 700, which cooperate with the side wall and the bottom wall of the containing barrel 100 to heat the solvent-free ink contained in the containing barrel 100, so as to avoid the situation that the temperature of the solvent-free ink in the containing barrel 100 is too low, thereby avoiding the situation that the viscosity of the solvent-free ink in the containing barrel 100 changes due to the change of the temperature, and further reducing the difficulty of controlling the viscosity of the solvent-free ink in the containing barrel 100. In addition, the bottom wall of the containing barrel 100 is fixedly provided with a plurality of supporting legs, which are uniformly and spacedly distributed along the circumference of the containing barrel 100, so as to ensure the stability of the containing barrel 100, and avoid placing the containing barrel 100 directly on other components, and further improve the heat preservation effect of the solvent-free ink in the containing barrel 100.

[0059] In the optional technical scheme of the embodiment, the side wall of the containing barrel 100 is provided with a residue discharge outlet 120, and the residue discharge outlet 120 is arranged close to the bottom wall of the containing barrel 100.

[0060] Specific combination Figure 1 As shown, the inner side of the bottom wall of the containing barrel 100 is provided as an inclined surface, the residue discharge outlet 120 is arranged close to the bottom wall of the containing barrel 100 and communicates with the inside of the containing barrel 100; and the depth of the side of the containing barrel 100 provided with the residue discharge outlet 120 is greater than the depth of the side of the containing barrel 100 without the residue discharge outlet 120, so as to more conveniently flow out the solvent-free ink in the containing barrel 100 through the residue discharge outlet 120.

[0061] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
