Detailed Description
The invention will be further described with reference to the accompanying drawings and specific embodiments.
The first embodiment.
As shown in fig. 1, the centralized oil supply system of the knitting machine according to the present embodiment includes a main oil tank 10 and a plurality of knitting machine oil tanks 20, wherein the knitting machine oil tank 20 is a self-contained oil tank of an existing knitting machine having a lubricating device, and belongs to a part of the knitting machine, and the knitting machine may be a conventional knitting machine such as a hosiery machine, a warp knitting machine, or a flat knitting machine.
Each oil distributing pipe 12 is provided with an electronic control switch, which may be a conventional switch, in this embodiment, an electromagnetic valve 13 is adopted as the electronic control switch, and the electromagnetic valve 13 is a normally closed electromagnetic valve. Each knitting machine oil tank 20 is provided with a liquid level switch 30 which is in communication connection with the corresponding electromagnetic valve 13 (namely, an electronic control switch), so that the liquid level switch 30 can be used for controlling the opening and closing of the electromagnetic valve 13 (namely, the electronic control switch) to realize automatic oiling. Preferably, in the present embodiment, the liquid level switch 30 includes a relay 31 and a first float switch 32 and a second float switch 32 electrically connected to the relay 31, respectively, the relay 31 is electrically connected to the corresponding electromagnetic valve 13 (i.e. an electronic control switch), and a trigger liquid level of the first liquid level switch 32 is higher than a trigger liquid level of the second float switch 33.
The main oil tank 10 is connected with a main oil pipe 11, specifically, the main oil pipe 11 is connected with the lower end of the main oil tank 10, the main oil pipe 11 is connected with a plurality of branch oil pipes 12 which are in one-to-one matching connection with the oil tanks 20 of the knitting machines, and preferably, the main oil pipe 10 is provided with a main valve (not shown in the figure), and of course, the main valve is not required. The oil pressure at the connecting position of the main oil pipe 11 and the main oil tank 10 is greater than the oil pressure at the connecting position of each branch oil pipe 12 and the corresponding knitting machine oil tank 20, so as to ensure that the oil can automatically flow into the knitting machine oil tank 20 from the main oil tank 10 after the corresponding valve is opened, specifically, in the embodiment, the horizontal position of the bottom of the main oil tank 10 is higher than the horizontal position of the top of each knitting machine oil tank 20, so as to ensure that the oil pressure at the connecting position of the main oil pipe 11 and the main oil tank 10 is greater than the oil pressure at the connecting position of each branch oil pipe 12 and the corresponding knitting machine oil tank 20, so as to facilitate the automatic oiling by using the gravity action and save the energy consumption, of course, the oil pressure at the connecting position of the main oil pipe 11 and the main oil tank 10 can also be greater than the oil pressure at the connecting position of each branch oil pipe 12 and the corresponding knitting machine oil, and will not be described in detail herein.
Taking one of the knitting machine oil tanks 20 as an example, in the using process, when the liquid level in the knitting machine oil tank 20 is reduced to trigger the first float switch 32, the relay 31 does not act, when the liquid level in the knitting machine oil tank 20 continuously drops and triggers the second float switch 33, the relay 32 acts to enable the electromagnetic valve 13 to be electrified and opened, the main oil tank 10 is communicated with the knitting machine oil tank 20, the knitting machine oil tank 20 is automatically oiled under the action of gravity, in the oiling process, the liquid level in the knitting machine oil tank 20 can slowly rise and trigger the second float switch 33, at the moment, the relay 31 does not act, when the liquid level in the knitting machine oil tank 20 continuously rises and triggers the first float switch 32, the relay 32 acts to enable the electromagnetic valve 13 to be powered off and closed, and oiling is stopped. Two level switch are formed through setting up two float switches, can ensure that knitting machine oil tank 20 interior liquid level has been close the bottom and begins to refuel again, avoid fluid deposit, and the volume of refueling at every turn is more relatively simultaneously, avoids needing frequently to refuel.
Example two.
Referring to fig. 1, the present embodiment is different from the first embodiment in that, instead of ensuring that the oil pressure at the connecting position of the main oil pipe 11 and the main oil tank 10 is greater than the oil pressure at the connecting position of each branch oil pipe 12 and the corresponding knitting machine oil tank 20, an oil pump, preferably a booster pump, is provided on the main oil pipe 11, and when any one or more of the solenoid valves 13 is opened, the booster pump is also automatically opened to pump the oil in the main oil tank 10 into the corresponding knitting machine oil tank 20.
The present invention has been described in detail with reference to the accompanying drawings, but the embodiments of the present invention are not limited to the above embodiments, and those skilled in the art can make various modifications to the present invention according to the prior art, and these all belong to the protection scope of the present invention.
