Description

Technical Field

[0001] The utility model relates to the technical field of film production, and particularly relates to a blockage prevention device for a lubricating oil pipeline of a tenter. Background Art

[0002] In the lubricating system of the tenter chain in a film production line, an oil injection motor slowly injects lubricating oil into a pipeline and flows out through a small oil injection port to lubricate the chain. When the production line stops for maintenance and the tenter stops running, the oil injection motor stops working. Due to the high internal temperature of the tenter and the non-flowing state of the lubricating oil in the pipeline, under the influence of high temperature for a long time, the lubricating oil will carbonize, and the carbide is likely to accumulate at the small oil injection port, resulting in blockage of the lubricating pipeline, affecting chain lubrication, posing serious equipment hazards, and reducing the equipment operation efficiency.

[0040] Referring to Figures 1 to 3 , in some embodiments of the present utility model, a clogging prevention device for a lubricating oil pipeline of a horizontal drawing machine includes: a horizontal drawing machine 600, a tee joint 100, an oil injection pipeline 200, a gas transmission assembly 300, an oil transmission assembly 400, and a driving module 500.

[0041] The input end of the driving module 500 is electrically connected to the horizontal drawing machine 600, and the output end of the driving module 500 is electrically connected to the gas transmission assembly 300. The tee joint 100 is provided with a first interface, a second interface, and a third interface.

[0042] In one embodiment, the tee joint 100 is a Y-shaped tee joint 100. The second interface and the third interface are both on the same side, both on one side of the tee joint 100, and the first interface is on the other side of the tee joint 100.

[0043] The first interface is communicated with one end of the oil injection pipeline 200. The other end of the oil injection pipeline 200 faces the horizontal drawing machine 600, and the lubricating oil in the oil injection pipeline 200 flows into the horizontal drawing machine 600.

[0044] The second interface is communicated with the gas transmission assembly 300. By being communicated with the second interface of the tee joint 100, the gas transmission assembly 300 can output compressed gas to the oil injection pipeline 200.

[0045] The third interface is communicated with the oil transmission assembly 400. By being communicated with the third interface of the tee joint 100, the oil transmission assembly 400 can output lubricating oil to the oil injection pipeline 200.

[0046] The horizontal drawing machine 600 sends a stop signal, that is, the horizontal drawing machine 600 is in a stopped state. The driving module 500 receives the stop signal and drives the gas transmission assembly 300 to output compressed gas into the oil injection pipeline 200, preventing the lubricating oil from staying for too long and carbonizing, thereby clogging the oil injection pipeline 200.

[0047] When the horizontal drawing machine 600 sends a stop signal, that is, when the horizontal drawing machine 600 is in a stopped state, the gas transmission assembly 300 is driven to operate. The gas transmission assembly 300 outputs compressed gas to blow out the lubricating oil in the oil injection pipeline 200 facing the horizontal drawing machine 600, preventing the lubricating oil from staying for too long and carbonizing and then clogging the oil pipe. There is no need to wait for the horizontal drawing machine 600 to cool down before entering the interior of the horizontal drawing machine 600 to replace the oil pipe and clean the carbide accumulated at the oil injection port 210, which is convenient for repairing the horizontal drawing machine 600 and improving the operating efficiency of the equipment.

[0048] Reference Figures 1 to 3 , in some embodiments of the present utility model, the driving module 500 includes: a driving power supply, a first relay KT1, and a second relay KT2.

[0049] One end of the normally closed contact of the first relay KT1 is electrically connected to the solenoid valve 330 in the gas transmission assembly 300, and the other end of the normally closed contact of the first relay KT1 is electrically connected to one end of the second normally open contact of the second relay KT2. The other end of the second normally open contact of the second relay KT2 is electrically connected to the driving power supply.

[0050] Among them, the driving power supply is a 24V DC power supply. Both the first relay KT1 and the second relay KT2 are time-delay relays.

[0051] One end of the first normally open contact of the second relay KT2 is electrically connected to the driving end of the first relay KT1, and the other end of the first normally open contact of the second relay KT2 is electrically connected to the driving power supply. The driving end of the second relay KT2 is electrically connected to the horizontal pulling machine 600, and the horizontal pulling machine 600 is electrically connected to the driving power supply.

[0052] In one embodiment, when the horizontal pulling machine 600 sends a stop signal, the driving end of the second relay KT2 is powered on, and both the first normally open contact and the second normally open contact of the second relay KT2 are delayed to close. The driving power supply passes through the second normally open contact of the second relay KT2 and the normally closed contact of the first relay KT1, so that the solenoid valve 330 in the gas transmission assembly 300 is powered on and conducts, and the gas transmission assembly 300 operates to output compressed gas. The compressed gas enters the oil injection pipeline 200 through the three-way joint 100 and blows out the lubricating oil in the oil injection pipeline 200.

[0053] Since the first normally open contact of the second relay KT2 is closed, the driving end of the first relay KT1 is powered on, and the normally closed contact of the first relay KT1 is delayed to open. At this time, the gas transmission assembly 300 has been operating for a period of time. Through the opened normally closed contact of the first relay KT1, the driving power supply cannot supply power to the solenoid valve 330 in the gas transmission assembly 300, and the gas transmission assembly 300 stops operating, and the compressed air stops entering the oil injection pipeline 200.

[0054] In one embodiment, when the horizontal pulling machine 600 outputs a start signal and the horizontal pulling machine 600 is in a start state, the driving end of the second relay KT2 loses power, both the first normally open contact and the second normally open contact of the second relay KT2 are disconnected, the driving end of the first relay KT1 loses power, and the normally closed contact of the first relay KT1 is closed, and the driving module 500 realizes automatic reset.

[0055] In this embodiment, the delay times of the first relay KT1 and the second relay KT2 can be adjusted according to the length of the pipeline, the output of the lubricating oil, or the temperature of the horizontal drawing machine 600. In the present utility model, the delay times of the relays are not specifically limited.

[0056] Referring to Figures 1 to 3 , in some embodiments of the present utility model, the horizontal drawing machine 600 includes: a horizontal drawing driver 610 and a horizontal drawing chain.

[0057] The output end of the horizontal drawing driver 610 is electrically connected to the drive power supply in the drive module 500, and the output end of the horizontal drawing driver 610 is also electrically connected to the drive end of the second relay KT2.

[0058] The horizontal drawing driver 610 can output a stop signal to make the drive end of the second relay KT2 energized, and the horizontal drawing driver 610 can also output a start signal to make the drive end of the second relay KT2 de-energized.

[0059] In one embodiment, a stop switch is provided on the horizontal drawing driver 610. One end of the stop switch is electrically connected to the drive power supply in the drive module 500, and the other end of the stop switch is electrically connected to the drive end of the second relay KT2.

[0060] When the stop switch is closed and the horizontal drawing driver 610 can output a stop signal, the drive end of the second relay KT2 is energized, and the first normally open contact and the second normally open contact of the second relay KT2 are both delayed to close. The drive power supply passes through the second normally open contact of the second relay KT2 and the normally closed contact of the first relay KT1, so that the solenoid valve 330 in the gas transmission assembly 300 is energized and conducted. The gas transmission assembly 300 operates to output compressed gas, and the compressed gas enters the oil injection pipeline 200 through the three-way joint 100 to blow out the lubricating oil in the oil injection pipeline 200.

[0061] When the stop switch is disconnected, the horizontal drawing driver 610 can output a start signal, and the horizontal drawing machine 600 is in the start state. Then the drive end of the second relay KT2 is de-energized, the first normally open contact and the second normally open contact of the second relay KT2 are both disconnected, the drive end of the first relay KT1 is de-energized, and the normally closed contact of the first relay KT1 is closed, and the drive module 500 realizes automatic reset.

[0062] The lubricating oil in the oil injection pipeline 200 flows into the horizontal drawing chain to lubricate the horizontal drawing chain.

[0063] Referring to Figures 1 to 3 , in some embodiments of the present utility model, the oil transmission assembly 400 includes: an oil injection motor 410, an oil distributor 420, and an oil transmission pipeline 430.

[0064] The oil injection motor 410 is electrically connected to the oil distributor 420. The oil injection motor 410 runs in the forward direction, driving the lead screw to push the plunger rod body of the oil distributor 420 forward, so that the oil distributor 420 outputs lubricating oil. One end of the oil delivery pipe 430 is communicated with the oil distributor 420, and the other end of the oil delivery pipe 430 is communicated with the third interface of the three-way joint 100.

[0065] The lubricating oil flows through the three-way joint 100 through the oil delivery pipe 430 and into the oil injection pipe 200. The other end of the oil injection pipe 200 is provided with an oil injection port 210. The lubricating oil is slowly injected into the oil injection pipe 200 and flows out through the small oil injection port 210 into the horizontal pulling chain, so that the horizontal pulling chain is lubricated under the action of the lubricating oil. Among them, the oil injection port 210 faces the horizontal pulling chain so that the lubricating oil can accurately flow into the horizontal pulling chain.

[0066] Refer to Figures 1 to 3 , in some embodiments of the present invention, the air delivery assembly 300 includes: a compressed air source 310, an air pipe 320, and a solenoid valve 330.

[0067] The compressed air source 310 is communicated with one end of the air pipe 320, and the second interface of the three-way joint 100 is communicated with the other end of the air pipe 320. The compressed air source 310 can provide compressed gas.

[0068] The solenoid valve 330 is installed at one end of the air pipe 320. The solenoid valve 330 is electrically connected to the normally closed contact of the first relay KT1. The solenoid valve 330 can adjust the conduction of the air pipe 320 so that compressed air flows into the air pipe 320. The solenoid valve 330 can also adjust and control the cut-off of the pipe so that the compressed air stops flowing into the air pipe 320.

[0069] In one embodiment, when the horizontal pulling driver 610 outputs a stop signal, the driving end of the second relay KT2 is powered on. The first normally open contact and the second normally open contact of the second relay KT2 are both delayed to close. The driving power supply passes through the second normally open contact of the second relay KT2 and the normally closed contact of the first relay KT1, so that the solenoid valve 330 is powered on and the valve core of the solenoid valve 330 opens. The air pipe 320 is conducted, and the compressed gas supplied by the compressed air source 310 sequentially enters the oil injection pipe 200 through the air pipe 320 and the three-way joint 100, and the compressed gas blows out the lubricating oil in the oil injection pipe 200.

[0070] In one embodiment, since the first normally open contact of the second relay KT2 is closed, the driving end of the first relay KT1 is powered on, and the normally closed contact of the first relay KT1 is delayed to open. At this time, the gas transmission assembly 300 has been operating for a period of time. Through the opened normally closed contact of the first relay KT1, the driving power supply cannot supply power to the solenoid valve 330, the solenoid valve 330 loses power, the valve core of the solenoid valve 330 closes, the air pipeline 320 is cut off, and the compressed gas supplied by the compressed gas source 310 cannot enter the air pipeline 320 to stop the compressed air from entering the oil injection pipeline 200.

[0071] When the horizontal drawing machine 600 sends a stop signal, that is, in the stopped state of the horizontal drawing machine 600, the gas transmission assembly 300 is driven to operate, and the gas transmission assembly 300 outputs compressed gas to blow out the lubricating oil in the oil injection pipeline 200 facing the horizontal drawing machine 600, avoiding carbonization caused by too long residence time of the lubricating oil and then blocking the oil pipe. It is not necessary to wait for the horizontal drawing machine 600 to cool down before entering the inside of the horizontal drawing machine 600 to replace the oil pipe and clean the carbide accumulated at the oil injection port 210, which is convenient for the maintenance of the horizontal drawing machine 600 and improves the operation efficiency of the equipment.

[0072] The preferred embodiments of the present invention have been specifically described above, but the present invention is not limited to the described embodiments. Those skilled in the art can also make various equivalent variations or substitutions without departing from the spirit of the present invention, and these equivalent variations or substitutions are all included within the scope defined by the claims of this application.
