The present invention will be described in detail with reference to the accompanying drawings so as to facilitate the understanding of the present invention by those skilled in the art, and the present invention is not limited thereto.
Fig. 1 is a schematic structural diagram of a preferred embodiment of the present invention.
The quantitative coating device comprises a first liquid storage tank 1, a heating device (not shown in the figure), four liquid quantity regulators 2 and four coating devices 3, wherein the heating device heats the first liquid storage tank 1; the first reservoir 1 is provided with liquid volume regulators 2, the liquid volume regulators 2 are in contact with the liquid in the first reservoir 1 to quantitatively convey the liquid in the first reservoir 1 to the application devices 3, and each liquid volume regulator 2 corresponds to one application device 3. The liquid quantity regulator 2 is a device which can deliver a fixed quantity of liquid from the reservoir 1 to the application device 3.
The liquid quantity regulator 2 is a metering pump or a combination of a pure water pump without metering function and a flowmeter. What adopt in this embodiment is the measuring pump, specifically is miniature gear pump, and the size of the tooth of gear pump is tiny, and precision is higher, so can not the weeping at the in-process of gear interlock, and the ration is more accurate. The micro-gear pump is connected to the application device 3 via a line, so that the gear pump can deliver a defined quantity of the liquid from the first reservoir 1 to the application device 3.
Gear pumps are rotary pumps that rely on the change in working volume and movement created between a pump cylinder and a meshing gear to deliver or pressurize a fluid. Two closed spaces are formed by two gears, a pump body and front and rear covers, when the gears rotate, the volume of the space on the gear disengagement side is increased from small to large to form vacuum, liquid is sucked in, and the volume of the space on the gear engagement side is decreased from large to small to squeeze the liquid into a pipeline, so that the liquid enters the coating device 3. The suction chamber and the discharge chamber are separated by a meshing line of two gears.
The heating device can be an electric heating device or an oil heating device. When the liquid in the first liquid storage tank 1 is inflammable or explosive, the oil heating jacket is safer, and the heat transfer is more uniform and stable.
The oil heating jacket comprises a second liquid storage tank 4 arranged outside the first liquid storage tank 1, the top surface of the second liquid storage tank 4 is in contact with the bottom surface of the first liquid storage tank 1, and a heating opening 5 is formed in the second liquid storage tank 4. The heater enters the second reservoir 4 from the heating port 5 to heat the liquid therein. So that the liquid in the first reservoir 1 is heated by the second reservoir 4, and the liquid in the first reservoir 1 is heated more uniformly.
And a temperature measuring device is also arranged on the second liquid storage tank 4. The heating temperature is controlled to prevent overheating or over-low temperature.
The temperature measuring device is arranged in a mode that a temperature measuring port 6 is arranged in the second liquid storage tank 4, and the temperature measuring device is arranged in the temperature measuring port 6 and directly measures the temperature of the liquid in the second liquid storage tank.
The coating device 3 described in this embodiment is a coating cartridge in which a material capable of adsorbing a solution, such as felt or sponge, is provided. When the liquid in the first liquid storage tank 1 is input into the coating box by the metering pump, namely the liquid is input into the felt in the coating box, a workpiece to be coated penetrates through the felt, and the liquid in the felt can be taken away.
In order to facilitate the operation, the coating box is provided with a box cover which can be opened and closed. The opening and closing modes can be various, for example, one side of the box cover is movably connected with the coating box, and the other side of the box cover is connected in a buckling mode; or the whole box cover is arranged on the coating box through a buckle.
Furthermore, a through hole is formed in a box cover of the coating box. In order to prevent the insoluble substances formed by the high temperature of the workpiece to be coated, which is likely to quickly solidify the liquid, the case cover is provided with a through hole for heat dissipation.
The first reservoir 1 is often a mixed solution, and in order to prevent the mixed solution from being unevenly distributed due to various reasons and causing poor application effect, a return port 8 is provided in the first reservoir 1, and the return port 8 is connected to a receiving device. In this embodiment, feed inlet 7 sets up in the left lower part of first reservoir 1, and backward flow mouth 8 is located the upper right portion of first reservoir 1, and solution gets into from feed inlet 7, passes whole reservoir, flows out from backward flow mouth 8, accomplishes the circulation, can guarantee the degree of consistency of liquid concentration in first reservoir 1 well.
The bottom of the first reservoir 1 is provided with a pipeline which passes through the second reservoir 4, so that the solution in the first reservoir 1 can flow out from the first outlet 9 at the bottom when the operation is stopped conveniently. Similarly, the bottom of the second reservoir 4 is provided with a second outlet 10, so that the heating oil can flow out from the second outlet 10.
The outlets of the two reservoirs may also be used as inlets for the liquid. It is also possible to provide a further inlet opening 7 in the first reservoir 1 and a separate oil inlet in the second reservoir 4.
The device of the preferred embodiment of the present invention is used for applying lubricant to enamelled wires in the manufacturing industry.
The lubricant is a synthetic wax in liquid-solid state, diluted to proper concentration with cyclohexane, and painted to the wire to lubricate it. Before quantitative coating is adopted, a metering pump continuously pumps coating liquid into a coating box, a coating felt absorbs the liquid in the coating box, a thread penetrates through the felt for coating, the amount absorbed by the felt is non-quantitative, and the amount of the thread is the same as the amount of the thread, after the thread is coated, a thinner cyclohexane is volatilized, the wax is remained, the amount of the liquid coated on the thread cannot be controlled, the concentration of the liquid needs to be controlled to enable the remaining wax to reach a required value, and the mass concentration of the wax is generally controlled to be 1%. The quantitative coating can control the liquid amount, so the concentration can be increased as long as the wax is coated on the wire, the mass concentration of the wax is generally controlled to be 3 percent, and the same 100 kg of diluent is taken as an example: 1% concentration contains 1 kg of wax, while 3% concentration contains 1 kg of wax only in 33.3 kg of diluent, and under the condition of achieving the same waxing effect, the former uses 99 kg of cyclohexane as diluent, while the latter only needs 32.3kg, 99-32.3 is 66.7 kg, so that 66.7/99 x 100% of cyclohexane is reduced to 67.3 about 70%, the production cost is greatly reduced, and the pollution of the cyclohexane to the atmosphere is reduced.
Firstly, lubricant is fed into the first reservoir 1 from the feed port 7 through a circulating pump, the return port 8 is connected with a receiving device (not shown in the figure), and the lubricant continuously enters from the feed port 7 and flows out from the return port 8, so that the stability of the concentration of the lubricant in the first reservoir 1 is ensured. The heating oil in the second liquid storage tank 4 is heated by a heater in the heating port 5, the temperature in the second liquid storage tank 4 is measured by a temperature measuring device, and the temperature is controlled to be proper.
The four metering pumps on the first liquid storage tank 1 are respectively communicated with the four coating boxes through pipelines, the metering pumps are started to pump the lubricant in the liquid storage tank 1 into the corresponding coating boxes, and the enameled wires to be coated penetrate through materials such as felts or sponges and the like in the coating boxes at a constant speed to adsorb liquid, so that the purpose of quantitative coating is achieved.
After use, the circulating pump and the metering pump are closed, and the liquid in the first liquid storage tank 1 and the liquid in the second liquid storage tank 4 are discharged from the corresponding first outlet 9 and the second outlet 10.
