Mechanical-electrical integrated device for keeping constant temperature of dyeing solution

[0022] Embodiment 1, an electromechanical integrated device for the constant temperature of the dye solution, comprising a heating plate 9 and a thermometer 10:

[0023] Such as figure 1 As shown, the thermometer 10 is provided with a connecting mechanism 15 fixedly connected to it. The connecting mechanism 15 includes a connecting bracket. The connecting bracket is fixedly connected to the heating plate 9. The heating plate 9 is provided with a surrounding heating coil 7 and the heating coil 7 One end is electrically connected to the power supply 14, and the other end is provided with a temperature control mechanism 1 electrically connected to it. The connecting bracket includes a first fixing block 11 and a second fixing block 8. The first fixing block 11 is fixedly connected to the thermometer 10, and the second The fixing block 8 is fixedly connected with the heating plate 9, and the thermometer 10 is used to detect the temperature of the dye solution when the heating plate 9 is working.

[0024] Therefore, the current flows from the power supply 14 through the heating plate 9 and then from the heating plate 9 to the temperature control mechanism 1. The temperature control mechanism 1 realizes the interruption of the entire circuit. The thermometer 10 can facilitate the operator to observe the temperature of the dye liquor in transportation in time.

[0025] Such as figure 1 As shown, the temperature control mechanism 1 includes a housing 6 and a movable arm 4. The housing 6 is sealed and made of copper. The conductive contact piece 5 and the iron piece 2 are fixedly connected in the housing 6, and the heating coil 7 and The iron sheet 2 is electrically connected. One end of the movable arm 4 is in constant contact contact with the iron sheet 2 and the other end is electrically connected to the conductive contact sheet 5, and the iron sheet 2 is grounded.

[0026] The movable arm 4 includes a lower metal sheet 12 and an upper metal sheet 13. The upper metal sheet 13 and the lower metal sheet 12 are bonded and connected. The thermal expansion coefficient of the lower metal sheet 12 is greater than that of the upper metal sheet 13, and the upper metal sheet 13 and the lower metal sheet 12 are both It is in circumferential contact with the heating coil 7, and the contact 3 is where the movable arm 4 and the iron sheet 2 frequently touch.

[0027] Therefore, after the current flows from the conductive contact sheet 5 to the upper metal sheet 13 and the lower metal sheet 12, the two metal sheets will undergo thermal expansion according to the thermal effect of the current, and because the thermal expansion coefficient of the lower metal sheet 12 is greater than that of the upper metal sheet 13, so It shows that the movable arm 4 will bend upwards, that is, the contact 3 is disconnected, so that the entire circuit is disconnected, and the heating plate 9 stops heating the dye solution.

[0028] At this time, the temperature of the dye solution rises sufficiently, and the movable arm 4 is affected by the temperature of the dye solution, and the contact 3 can still be kept in an open state, that is, the heating of the dye solution is stopped.

[0029] The second embodiment is different from the first embodiment in that: the temperature control mechanism 1 also includes a bottom plate 25 and a liquid storage tank 16. The liquid storage tank 16 is provided with an independent driving layer 17 and a small bidirectional pump 18 is fixedly connected to the driving layer 17 One end of the small two-way pump 18 is connected with the upper layer of the liquid storage barrel 16, and the other end is connected with the lower layer of the liquid storage barrel 16. The lower layer of the liquid storage barrel 16 is provided with a U-shaped pipe 19 communicating with it, and the U-shaped pipe 19 is fixedly connected with a solenoid valve 20 A floating block 23 is provided at one end away from the liquid storage tank 16, and a linkage member 24 is provided on the floating block 23.

[0030] Such as figure 2 As shown, the linkage component 24 includes a top rod 241, one end of the top rod 241 is fixedly connected to the floating block 23 and protrudes out of the U-shaped pipe 19, the other end is fixedly connected with a pressure rod 243, and the bottom plate 25 is fixedly connected with a sliding groove 253 and The connecting table 251, the top rod 241 is slidingly connected with the sliding groove 253, the connecting table 251 is hinged with the pressing rod 243, the end of the pressing rod 243 away from the top rod 241 is fixedly connected with an electric iron sheet 242, and the bottom plate 25 is also fixedly connected with a conductive sheet 252 is in contact with the PLC board 21, the pad iron sheet is in contact with the conductive sheet 252, the thermometer 10 is provided with a temperature sensor 22, the temperature sensor 22 is electrically connected to the PLC board 21, the PLC board 21 is electrically connected to the solenoid valve 20, and the PLC board 21 is electrically connected to The small bidirectional pump 18 is electrically connected, and the conductive sheet 252 is electrically connected to the heating sheet 9.

[0031] Therefore, after the heating plate 9 continues to heat the dye solution, the thermometer 10 can detect the temperature of the dye solution, and the temperature sensor 22 can send an electric signal to the PLC board 21 when the temperature of the dye solution is in a lower range, so that the PLC The plate 21 controls the solenoid valve 20 to open, and the small two-way pump 18 is turned on. The small two-way pump 18 starts to guide the upper layer of liquid storage to the lower layer of the liquid storage tank 16, and flows out through the U-shaped pipe 19. After the liquid flow reaches a certain level , The floating block 23 on the other layer of the U-shaped pipe 19 will be lifted up by the liquid, so that the floating block 23 will push up the pressure rod 243 through the top rod 241, that is, the other end of the pressure rod 243 is on the electric iron sheet 242 and the bottom plate 25. The contact of the conductive sheet 252, that is, the heating sheet 9 electrically connected to the conductive sheet 252, starts to work, and starts to continuously raise the temperature of the dye solution.

[0032] After the dye solution temperature rises enough, that is, after the temperature sensor 22 detects that the dye solution temperature is at an appropriate temperature, the temperature sensor 22 sends an electrical signal to the PLC board 21, and then the PLC board 21 controls the small two-way pump 18 to realize the U-shaped pipe 19 and The liquid in the lower layer of the liquid storage barrel 16 is pumped to the upper layer of the liquid storage barrel 16, and the solenoid valve 20 is closed at the end, that is, the liquid level of the end of the U-shaped pipe 19 with the float 23 drops, and the float 23 pulls the pressure rod 243 downward, Finally, the electric iron sheet 242 is disconnected from the conductive sheet 252, the heating sheet 9 no longer works, and the constant temperature control of the dye solution temperature within a certain range is realized.
