Description

Technical Field

[0001] This utility model relates to the field of lead-acid battery manufacturing technology, and in particular to an intermittent lubrication system for continuous casting of grid plates. Background Technology

[0002] The grid acts as a conductor and framework in the plates of a lead-acid battery, and is a key material in the manufacture of lead-acid batteries. During the grid casting process, a related mold lubrication system is required to address issues such as the difficulty in removing the cast grid from the rotating mold and severe wear between the rotating and fixed molds, ensuring smooth grid casting and product quality.

[0003] In the process of grid casting, the continuous casting lubricating oil is a one-time use and the amount used is very small. Traditional mold lubrication systems use micro-control valves to control the flow rate. However, the channels of the micro-control valves are very small and they are prone to blockage, resulting in poor lubrication of the mold, affecting the service life of the mold and the casting quality of the grid. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide an intermittent lubrication system for continuous casting of plate grids, which can effectively reduce the occurrence of blockage and thus improve the lubrication effect.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] An intermittent lubrication system for continuous casting of grid plates includes a PLC, a lubricating oil tank, a pneumatic lubricating oil pump, a bracket, a pressurized metering dispenser, and an oil brushing assembly.

[0007] Both the pressurized metering dispenser and the oil brushing assembly are mounted on the bracket, with the oil brushing assembly located below the pressurized metering dispenser. The pressurized metering dispenser includes a main oil pipe and multiple metering oil outlets connected to the main oil pipe. The multiple metering oil outlets are located on the lower side of the main oil pipe and arranged along the length of the main oil pipe. The oil brushing assembly includes an oil trough, with the upper opening of the oil trough facing the multiple metering oil outlets, and an oil brush clamped in the lower opening of the oil trough.

[0008] The PLC is used to control the starting frequency of the pneumatic lubricating oil pump to achieve intermittent oil supply. The oil inlet of the pneumatic lubricating oil pump is connected to the lubricating oil tank, and the oil outlet of the pneumatic lubricating oil pump is connected to the main oil pipe.

[0009] Furthermore, the oil outlet of the pneumatic lubricating oil pump is connected to the main oil pipe through an oil delivery pipeline.

[0010] Furthermore, the pneumatic lubricating oil pump is provided with an air inlet.

[0011] Furthermore, the lubricating oil tank is provided with an oil filling port.

[0012] Furthermore, the pneumatic lubricating oil pump is installed inside the lubricating oil tank, and a control panel for the pneumatic lubricating oil pump is installed on the top of the lubricating oil tank.

[0013] Furthermore, the oil trough has a V-shaped structure, and the width of the upper opening of the oil trough is greater than the width of the lower opening of the oil trough.

[0014] Furthermore, the pneumatic lubricating oil pump uses a relay to control the switch of its own power supply, and the signal output terminal of the PLC is electrically connected to the control terminal of the relay.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] The intermittent lubrication system for continuous casting of slab grids provided by this utility model has a lubricating oil tank for storing lubricating oil, a PLC for controlling the starting frequency of the pneumatic lubricating oil pump to achieve intermittent oil supply, a constant amount of oil added to each metering port of the pressurized metering distributor, an oil trough of the oil brush assembly for receiving the lubricating oil discharged from the metering port, and lubrication achieved by the oil brush of the oil brush assembly contacting the mold.

[0017] Because it uses a pressurized quantitative distributor, which is a device that distributes lubricating oil under external pressure, it can ensure that the fluid overcomes the oil circuit resistance to flow, thereby effectively reducing blockage and improving the lubrication effect. Moreover, it can control the starting frequency of the pneumatic lubricating oil pump through PLC, thereby achieving the effect of flow control. Attached Figure Description

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0028] refer to Figures 1 to 3 This utility model provides an intermittent lubrication system for continuous casting of grid plates. The intermittent lubrication system includes a PLC, a lubricating oil tank 100, a pneumatic lubricating oil pump 200, a bracket 300, a pressurized metering distributor 400, and an oil brushing assembly 500.

[0029] In the intermittent lubrication system of this utility model embodiment, both the pressurized metering dispenser 400 and the oil brush assembly 500 are mounted on the bracket 300, with the oil brush assembly 500 positioned below the pressurized metering dispenser 400. The pressurized metering dispenser 400 includes a main oil pipe 401 and multiple metering oil outlets 402 communicating with the main oil pipe 401. The multiple metering oil outlets 402 are located below the main oil pipe 401 and arranged along its length. The oil brush assembly 500 includes an oil groove 501, with its upper opening opposite to the multiple metering oil outlets 402, and an oil brush 502 clamped in the lower opening of the oil groove 501.

[0030] In addition, the PLC is used to control the starting frequency of the pneumatic lubricating oil pump 200 to achieve intermittent oil supply. The oil inlet of the pneumatic lubricating oil pump 200 is connected to the lubricating oil tank 100, and the oil outlet of the pneumatic lubricating oil pump 200 is connected to the main oil pipe 401.

[0031] Specifically, in the intermittent lubrication system of this utility model embodiment, the oil outlet of the pneumatic lubricating oil pump 200 is connected to the main oil pipe 401 through the oil delivery pipe 201; the pneumatic lubricating oil pump 200 is provided with an air inlet 202; and the lubricating oil tank 100 is provided with a filling port 101.

[0032] Preferably, in the intermittent lubrication system of this utility model embodiment, the pneumatic lubricating oil pump 200 is installed inside the lubricating oil tank 100, and the control panel 203 of the pneumatic lubricating oil pump 200 is installed on the top of the lubricating oil tank 100; this arrangement can make the oil supply part of the intermittent lubrication system occupy less space and improve space utilization.

[0033] Preferably, in the intermittent lubrication system of this utility model embodiment, the oil groove 501 has a V-shaped structure, that is, the cross section of the oil groove 501 is V-shaped, and the width of the upper opening of the oil groove 501 is greater than the width of the lower opening of the oil groove 501. This facilitates the receiving of lubricating oil discharged from the quantitative oil distribution port 402 and facilitates the guiding of lubricating oil to the oil brush 502.

[0034] Preferably, in the intermittent lubrication system of this embodiment, the pneumatic lubricating oil pump 200 uses a relay to control its own power supply switch, and the signal output terminal of the PLC is electrically connected to the control terminal (i.e., the relay coil) of the relay. Specifically, when the signal output terminal of the PLC outputs a preset signal, the relay coil is energized, causing the controlled terminal of the relay, i.e., the relay contact, to close, thereby starting the oil pump. When the signal at the signal output terminal of the PLC disappears, the relay coil is de-energized, causing the relay contact to open, thereby shutting down the oil pump.

[0035] The intermittent lubrication system for continuous casting of grid plates provided in this embodiment of the utility model works as follows: the lubricating oil tank 100 is used to store lubricating oil, the PLC is used to control the starting frequency of the pneumatic lubricating oil pump 200 to achieve intermittent oil supply, the amount of oil added to each metering oil outlet 402 of the pressurized metering distributor 400 is constant, the oil trough 501 of the brushing assembly 500 is used to receive the lubricating oil discharged from the metering oil outlet 402, and the oil brush 502 of the brushing assembly 500 contacts the mold to achieve lubrication.

[0036] The device employs a pressurized quantitative distributor 400, which is a device that distributes lubricating oil under external pressure. This ensures that the fluid overcomes the resistance of the oil circuit and flows, thereby effectively reducing blockages and improving lubrication. Furthermore, the device can control the starting frequency of the pneumatic lubricating oil pump 200 via PLC, thus achieving flow control.

[0037] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
