Detailed Description
The invention will be further explained with reference to the drawings.
The invention provides an enameled wire lubricant coating device, which comprises:
the coating device comprises a coating groove 1, wherein the interior of the coating groove 1 is divided into a plurality of functional grooves, the functional grooves comprise a first functional groove 11, a second functional groove 12 and a third functional groove 13 which are sequentially arranged, and adjacent functional grooves are communicated through a through hole 15;
a lubricant supply mechanism 2 connected to the first functional tank 11 through a pipe;
and a roller coating mechanism 3 disposed above the third functional tank 13.
Specifically, as shown in fig. 1 of the drawings, the coating tank 1 is internally divided into a first functional tank 11, a second functional tank 12 and a third functional tank 13 which are arranged in sequence, and the three functional tanks are communicated with each other through a through hole 15 between each two functional tanks. Wherein the first function is connected via a line to the lubricant supply 2 for the feeding of lubricant; a roller coating mechanism 3 is arranged above the third functional groove 13 and is used for directly coating; the second functional groove 12 is located between the first functional groove 11 and the third functional groove 13 for buffering when lubricant is fed.
The buffer effect of the second functional groove 12, in particular, when the lubricant supply mechanism 2 feeds the lubricant into the first functional groove 11, because the lubricant is usually pumped in, the lubricant has a large kinetic energy and flow rate when entering the first functional groove 11, and thus in the first functional groove 11, the lubricant level will rise instantaneously and the kinetic energy will be reduced. In addition, the first functional groove 11 is communicated with the second functional groove 12 only through the through hole 15, and the aperture of the through hole 15 is small, so when the lubricant enters the second functional groove 12 through the through hole 15, the flow rate and the kinetic energy of the lubricant are reduced, and the liquid level of the lubricant in the second functional groove 12 rises stably. Meanwhile, when the lubricant in the second functional groove 12 enters the third functional groove 13 through the through hole 15, the kinetic energy of the lubricant is further reduced, and the flow rate is further reduced, so that the lubricant enters the third functional groove 13 more stably, and the lubricant level in the third functional groove 13 is basically and stably and uniformly increased. Therefore, when lubricant is input, the first functional groove 11 has a certain buffer function, and the second functional groove 12 plays a main buffer function, so that the lubricant cannot be led out to cause the instantaneous rise of the liquid level at the inlet when entering the third functional groove 13, and the problem of uneven distribution of the lubricant coating amount on the roller coating mechanism 3 caused by the sudden rise of the local liquid level is avoided.
It should be noted that the tops of the first functional groove 11 and the second functional groove 12 shown in fig. 1 are open, which is provided on the premise that the pumping amount of the lubricant can be accurately controlled. In practical application, the tops of the first functional groove 11 and the second functional groove 12 may be closed according to specific situations, so as to avoid lubricant overflow.
In one embodiment, the through-hole 15 opens on the partition structure 14 between adjacent functional grooves and near the groove bottoms of the functional grooves.
In particular, the partition structure 14 may be a partition as shown in fig. 1, and the through hole 15 is opened at the bottom of the partition close to the bottom of the functional tank, and the purpose of the through hole 15 is that: so that the lubricant is input from the groove bottom of the functional groove, and the liquid level of the lubricant is ensured to stably rise from bottom to top.
In one embodiment, the through holes 15 connecting the first functional groove 11 and the second functional groove 12 are relatively completely staggered from the through holes 15 connecting the second functional groove 12 and the third functional groove 13.
Specifically, the two through holes 15 are completely staggered relatively, so that the lubricant does not continuously pass through the two through holes 15 and directly enters the third functional groove 13 after entering the first functional groove 11, and the lubricant fully plays a role in buffering through the second functional groove 12.
In one embodiment, the aperture of the through-hole 15 communicating the first functional groove 11 and the second functional groove 12 is larger than the aperture of the through-hole 15 communicating the second functional groove 12 and the third functional groove 13.
Specifically, as shown in fig. 1, when lubricant is pumped into the first functional groove 11, the kinetic energy and the flow rate of the lubricant are large, and the space of the first functional groove 11 is limited, so that the lubricant can be prevented from filling the first functional groove 11 instantaneously. The hole diameter of the through hole 15 communicating the first functional groove 11 and the second functional groove 12 is increased so that the lubricant in the first functional groove 11 can be more quickly introduced into the second functional groove 12 while ensuring the cushioning effect.
In one embodiment, the coating tank 1 is provided with a temperature control device, which includes a temperature detection device and a heating device.
In particular, temperature control means (not shown in the drawings) on the coating tank 1 are used to ensure that the lubricant is at a suitable working temperature, typically 40-50 ℃, to ensure that the lubricant has a suitable fluidity. The temperature detecting means monitors the temperature of the lubricant in the coating tank 1 in real time, and the heating means operates and heats the lubricant when the temperature is lower than the operating temperature. Wherein, the heating device is arranged on the outer wall or the bottom of the coating tank 1, and the structure can adopt a jacket type heating structure.
In one embodiment, a liquid level indicator 4 for indicating the lubricant level in the third functional tank 13 is provided on one side end surface of the coating tank 1 near the third functional tank 13.
Specifically, the liquid level display 4 can reflect the lubricant liquid level in the third functional tank 13 in real time, so as to ensure that the lubricant is replenished in time before the lubricant liquid level in the third functional tank 13 is lower than the working liquid level lower limit.
In one embodiment, the lubricant supply mechanism 2 includes:
a storage tank 21 for storing lubricant;
and the delivery pump 22 is arranged on the storage tank 21, and the output end of the delivery pump 22 is connected with the first functional tank 11 through a delivery pipe 23.
Preferably, the bottom of the storage box 21 is further opened with a drain 211. Drain 211 is used to drain lubricant from storage tank 21, to facilitate maintenance of storage tank 21 and to prevent lubricant from freezing as it is stored in storage tank 21 during a shutdown event.
Preferably, the storage tank 21 is provided with a liquid level display 4 and a temperature control device. Wherein the temperature control device on the storage tank 21 ensures that the temperature of the lubricant in the storage tank 21 is maintained between 28-40 ℃.
In one embodiment, the storage tank 21 is also communicated with the first functional tank 11 through a return pipe 24;
wherein, one end of the return pipe 24 connected with the first functional groove 11 extends into the first functional groove 11, and the mouth of the return pipe is upward and higher than the groove bottom of the first functional groove 11.
Specifically, the return pipe 24 is used for returning the pumped redundant lubricant from the first functional tank 11 to the storage tank 21, and the nozzle of the return pipe 24 is higher than the bottom of the first functional tank 11, so as to ensure that the first functional tank 11 has a certain amount of lubricant, and the lubricant will only flow back when the pumped amount of the lubricant is too large, which causes the liquid level of the lubricant to be higher than the nozzle of the return pipe 24.
In one embodiment, the roll coating mechanism 3 includes:
a coating roller 31 horizontally disposed above the third functional bath 13 with a lower portion thereof located in the third functional bath 13;
and a drive motor 32 that is connected to and drives the coating roller 31 through a gear mechanism 33.
Specifically, as shown in fig. 1 of the drawings, the gear mechanism 33 includes a driven gear provided on the shaft of the coating drum 31 and a drive gear provided on the output shaft of the drive motor 32. The specific structure of the gear mechanism 33 can be selected adaptively, and may be a cylindrical gear as shown in fig. 1, or may be a bevel gear. Meanwhile, according to practical situations, the gear mechanism 33 may be replaced by other transmission structures, for example, a chain wheel and chain mechanism or a shaft directly connecting the output shaft of the driving motor 32 and the coating roller 31 between couplings may be adopted.
