Description

Technical Field

[0001] The utility model relates to the technical field of lubrication systems, and more specifically, to a chain clip track oil injection lubrication system and a diaphragm stretching system. Background Art

[0002] In recent years, lithium-ion batteries have been widely used in fields such as smart phones, tablet computers, smart wearables, power tools, and electric vehicles.

[0003] With the wide application of lithium-ion batteries, consumers' requirements for the usage environment and demands of lithium-ion batteries are constantly increasing. This requires lithium-ion batteries to have high safety while taking into account high and low temperature performance, and at the same time, the cost requirements are constantly decreasing. As an important component of lithium-ion batteries, the battery diaphragm determines the interface structure, internal resistance, etc. of the battery, and directly affects the performance of the battery such as cycle life, capacity, and safety. On the battery diaphragm production line, the high-speed horizontal stretching track is one of the important core devices. However, when the existing horizontal stretching track runs at high speed, a large amount of heat is generated due to friction between the chain clip and the track, which makes the track vulnerable to heat fatigue. The chain clip bearings and the track surface are worn without lubrication under high temperature conditions, affecting the service life and working stability of the equipment. In addition, insufficient lubrication will also lead to increased wear of the track and reduce the operating efficiency of the equipment.

[0004] The existing oil injection method is to inject oil once before the equipment runs. However, when the existing horizontal stretching track runs at high speed in a high-temperature oven, the production temperature in the oven is 100 - 150 °C, and the lubricating oil on the track will quickly volatilize in the high-temperature oven, resulting in wear of the track surface and the walking rollers on the chain clip.

[0032] See Figure 1 and Figure 2 , the utility model discloses a chain clip track oil injection lubrication system. The thin oil coming out of the lubricating pump 2 in the whole lubrication system is precisely and quantitatively circulated and distributed through a progressive distributor to each lubrication point.

[0033] The chain clip track oil injection lubrication system includes a chain clip track 9, a control system 1, a lubricating pump 2, a main pipeline safety overflow valve 3, a branch pipeline safety overflow valve 4, a mechanical pressure gauge 5, a pressure switch 6, a first-stage distributor 7, and a second-stage distributor 8. Among them, the lubricating pump 2 is a high-pressure lubricating pump 2. The top cover of the fuel tank of the high-pressure lubricating pump 2 is internally provided with a float liquid level switch, and the top cover is provided with a filtered fuel filling port.

[0034] The control system 1 is electrically connected to the lubricating pump 2. The oil outlet end of the lubricating pump 2 is connected to the first-stage distributor 7 through a first pipeline. The first-stage distributor 7 includes a first counting pulse signal module, which is used to measure the oil supply times of the first-stage distributor 7, and the first counting pulse signal module is signal-connected to the control system 1. A main pipeline safety overflow valve 3 and a pressure switch 6 are arranged on the first pipeline. The main pipeline safety overflow valve 3 is communicated with the fuel tank of the lubricating pump 2, and the action threshold of the main pipeline safety overflow valve 3 is 160 bar. The action threshold of the pressure switch 6 is 100 bar, and the pressure switch 6 is signal-connected to the control system 1.

[0035] A plurality of secondary distributors 8 are provided, and the plurality of secondary distributors 8 are arranged in parallel. The secondary distributor 8 includes a second counting pulse signal module for measuring the number of times of oil supply of the secondary distributor 8, and the second counting pulse signal module is signal-connected to the control system 1. Each secondary distributor 8 is individually connected to the oil outlet end of the primary distributor 7 through a separate second pipeline, and a branch pipeline safety overflow valve 4 is provided on each second pipeline. The action threshold of the branch pipeline safety overflow valve 4 is 120 bar. The branch pipeline safety overflow valve 4 is communicated with the fuel tank; a plurality of oil outlet pipelines are arranged in parallel at the oil outlet end of each secondary distributor 8; the oil outlet points of the plurality of oil outlet pipelines are sequentially arranged at a plurality of lubrication points (the first lubrication point A11, the second lubrication point A12, the third lubrication point A21, the fourth lubrication point A22, the fifth lubrication point B11, the sixth lubrication point B12, the seventh lubrication point B13, the eighth lubrication point B14, the ninth lubrication point B21, the tenth lubrication point B22, the eleventh lubrication point B23, the twelfth lubrication point B24, the thirteenth lubrication point C11, the fourteenth lubrication point C12, the fifteenth lubrication point C13, the sixteenth lubrication point C21, the seventeenth lubrication point C22, the eighteenth lubrication point C23) in the length direction of the chain gripper track 9.

[0036] The mechanical pressure gauge 5 is installed on the first overflow pipeline connecting the main pipeline safety overflow valve 3 and the first pipeline and on the second overflow pipeline connecting the branch pipeline safety overflow valve 4 and the second pipeline for detecting the oil pressure of the first overflow pipeline and the second overflow pipeline.

[0037] Working principle:

[0038] Under normal circumstances, the oil output of the oil outlets of multiple oil pipelines is approximately equal. Before the inlet of the first-stage distributor 7 at the system outlet, there is a 160-bar safety relief valve (main pipeline safety relief valve 3), and after the first-stage distributor, there is a 120-bar safety relief valve (sub-pipeline safety relief valve 4); at the outlet of the lubricating pump 2, there is a pressure switch 6, and the closing pressure of the pressure switch 6 is 100 bar. Once the lubrication system is blocked and the pressure exceeds 100 bar, the pressure switch 6 closes. System description: When the system is discharging oil normally, the lubricating pump 2 starts, and the two-stage distributor continuously operates under the drive of the lubricating pump 2. Both the first-stage distributor 7 and the second-stage distributor 8 output counting pulse signals, and the pressure switch 6 has no signal output. When the set pulses are reached, the control system 1 is powered off, the lubricating pump 2 stops working, and the first-stage distributor 7 and the second-stage distributor 8 stop at the current position. When the first-stage distributor 7 and the second-stage distributor 8 are started next time, they count and work from the current position. If a certain second-stage distributor 8 malfunctions, once a certain second-stage distributor 8 is blocked, the corresponding second-stage distributor 8 does not work and has no pulse signal output, and the other five second-stage distributors 8 work normally and the pulse counting is normal; at the same time, due to the excessive pressure of this path flowing back to the fuel tank through the sub-pipeline safety relief valve 4, at this time, the pressure in front of the first-stage distributor 7 exceeds 100 bar and the pressure switch 6 closes. If the first-stage distributor 7 malfunctions, once the first-stage distributor 7 is blocked, the corresponding distributor does not work and has no pulse signal output, and all six second-stage distributors 8 cannot work normally and there is no pulse output for the pulse counting; at this time, the excessive pressure in the pipeline flows back to the fuel tank through the 160-bar main pipeline safety relief valve 3, and at this time, the pressure in front of the first-stage distributor 7 exceeds 100 bar and the pressure switch 6 closes. If the lubricating pump 2 has abnormal oil output, once the lubricating pump 2 does not discharge oil, all seven distributors (one first-stage distributor 7 and six second-stage distributors 8) do not work and have no pulse signal output, and at this time, the pressure in front of the first-stage distributor 7 is lower than 100 bar and the pressure switch 6 disconnects. If the pressure switch 6 malfunctions, all seven distributors have pulse signal outputs. At this time, if the pressure switch 6 closes, it may be that the pressure setting of the pressure switch 6 is incorrect or the local pipeline is flattened, resulting in the triggering of the pressure signal.

[0039] In the second aspect of the present invention, a diaphragm stretching system is provided, including a high-temperature oven and a chain clamp track oil injection lubrication system arranged in the high-temperature oven. The chain clamp track oil injection lubrication system adopts the chain clamp track oil injection lubrication system of the first aspect of the present invention.

[0040] In summary, the chain clamp track oil injection lubrication system of the present invention supplies oil to each necessary lubrication part of the equipment as needed through a complete set of oil supply systems, which can reduce the frictional resistance, reduce contact wear, and lower the temperature of the friction surface. At the same time, it also plays a certain role in rust prevention, shock absorption, and sealing assistance.

[0041] The advantages of the present invention are as follows:

[0042] 1. The lubricating pump is successively connected to each level of distributors to alternately supply the grease to each lubrication point. Sensors are provided on the distributors to monitor the working state of the whole system, and the oil output is controlled by the running time. A pressure switch is installed between the lubricating pump and the distributors for fault early warning.

[0043] 2. The distributor supplies oil to each lubrication point one by one in a progressive manner through the sequential movement of each plunger. The running state of the whole distributor can be observed through the self - contained indicating rod, and the running condition of the whole distributor can be detected by installing sensors. Once a blockage occurs, an alarm can be realized.

[0044] 3. The sensor of the secondary distributor can be used to detect whether there is an oil circuit in this distributor that cannot work properly, but it does not affect the normal working of the oil circuits of other distributors. It is similar to temporarily "short - circuiting" this secondary distributor, and shutting down for maintenance and troubleshooting to prevent the blockage of a single pipeline or distributor from affecting the normal oil injection of all pipelines in the whole system, ensuring the lubrication performance of the track and chain clips, and extending the service life and precision of mechanical equipment.

[0045] 4. The pressure grease is transported to the distributors through the main lubricating pipeline, and the distributors then distribute the grease to each lubrication point. The distributor sensors detect the oil supply volume of the system in real - time and transmit it to the control system. When the oil injection volume reaches the set value, the lubricating pump stops working, and the monitor count of the control system is incremented by 1. The whole oil supply process of the system ends and enters the next working cycle.

Those skilled in the art should understand that the above embodiments can be modified without departing from the scope and spirit of the present utility model.
