Description

Technical Field

[0001] The utility model relates to the technical field of vulcanizer lubrication, and particularly relates to an oil injection lubrication system for a tire vulcanizer. Background Art

[0002] In the tire industry, multiple vulcanizers are usually neatly arranged along both sides of a trench to form a group of equipment. Each moving part of the vulcanizer makes periodic reciprocating motions according to production requirements, with relatively large friction. Therefore, it is necessary to regularly inject oil into the vulcanizer for lubrication.

[0003] At present, there are mainly two ways to lubricate the vulcanizer. One is manual application, and the other is to use a dry oil pump to determine the lubrication period according to the state of the lubricating oil on the moving parts after several production cycles and automatically inject oil. Therefore, adding lubricating oil to the oil cup of the dry oil pump has become an important part of the maintenance of the vulcanizer.

[0004] Generally, lubricating oil is added to the oil cup of the dry oil pump manually. Workers need to add lubricating oil to the oil cups of the dry oil pumps of each vulcanizer respectively, which will result in problems such as a long refueling cycle, high labor intensity, and dirt brought by the oil during refueling. At the same time, the existing oil injection lubrication operation lacks a detection device, so that workers cannot detect in time whether the oil in the oil cup of the dry oil pump is full. Once the oil is overfilled and spills, it will cause waste of oil products, increase the maintenance cost, and affect the normal operation of the vulcanizer. Content of the Utility Model

[0005] The purpose of the utility model is to solve the above technical deficiencies and provide an oil injection lubrication system for a tire vulcanizer.

[0006] To this end, the utility model provides an oil injection lubrication system for a tire vulcanizer, which includes a centralized lubrication system end and multiple vulcanizer ends. The centralized lubrication system end transports the lubricating oil in the storage tank to the multiple vulcanizer ends. Each vulcanizer end is provided with a detection device for detecting whether the oil is full, and the detection device transmits a signal to the centralized lubrication system end.

[0007] Preferably, the centralized lubrication system end includes a main oil pump, a main solenoid valve, a main oil pipe, and a PLC control system. The inlet of the main oil pump is connected to the storage tank, the outlet of the main oil pump is connected to the main oil pipe, the main solenoid valve is installed on the main oil pipe, and the main solenoid valve is electrically connected to the PLC control system.

[0008] Preferably, the vulcanizer end includes a branch oil pipe, a branch solenoid valve, and a dry oil pump oil cup. One end of the branch oil pipe is communicated with the main oil pipe, and the other end is communicated with the dry oil pump oil cup. The branch solenoid valve is installed on the branch oil pipe, the branch solenoid valve is electrically connected to the PLC control system, and the dry oil pump oil cup is connected to the detection device.

[0009] Preferably, the detection device includes a pressing plate, a spring, a mounting seat and a signal switch. The dry oil pump oil cup is placed on the pressing plate. The mounting seat is arranged below the pressing plate. The spring is installed between the pressing plate and the mounting seat. The signal switch is fixedly installed at the middle position of the mounting seat. The signal switch is signal-connected to the PLC control system.

[0010] Preferably, both ends of the pressing plate are bent upward to form an inverted trapezoid.

[0011] Preferably, an iron plate is fixedly installed at the top of the mounting seat, and the signal switch is fixedly installed at the top of the iron plate.

[0012] The beneficial effects of the present utility model are as follows: The present utility model provides an oil injection lubrication system for a tire vulcanizer, and has the following beneficial effects.

[0013] (1) The centralized lubrication system supplies oil from the centralized lubrication system end to each vulcanizer end. Workers only need to add enough oil to the storage tank at the centralized lubrication system end, and there is no need to frequently add oil to the refueling trolley (a refueling vehicle pushed by people, a refueling tool) and then push it to each machine station. The cumbersome steps of connecting power, connecting pipes, disconnecting power, and disconnecting pipes for the refueling trolley are omitted, which reduces the workload and labor intensity of workers, greatly improves the efficiency of oil injection lubrication of the vulcanizer, shortens the refueling cycle, reduces the emulsification and deterioration of oil products during long-term storage in the pipeline, and can also avoid the oil pollution problem caused by oil products during refueling, further reducing the input cost of lubricating oil, changing from a one-time large purchase to a small batch purchase in batches;

[0014] (2) The setting of the detection device saves the labor cost of having a special person to observe the oil volume in the dry oil pump oil cup in real time during refueling, can detect in time whether the oil cup is full of oil, prevent the lubricating oil from overflowing, reduce oil product waste, and ensure the normal operation of the vulcanizer;

[0015] (3) The lubricating oil in the storage tank is respectively transported to each sub-oil pipe through the main oil pipe, and then the lubricating oil is injected into the dry oil pump oil cups corresponding to each vulcanizer through the sub-oil pipe and the sub-solenoid valve. The main oil pipe is installed in the middle of the vulcanizer equipment group, and the environmental temperature is high, so that the oil product can maintain good fluidity;

[0016] ⑷ By monitoring the time interval of the signal switch signal transmitted to the PLC control system, it is judged whether there is any abnormality in the lubrication system of the dry oil pump at each vulcanizer end. If the time interval is too long, there is a blockage in the oil circuit and the equipment cannot be effectively lubricated; if the time interval is too short, there is a leakage in the lubricating oil circuit of the equipment. The maintenance personnel can judge the faulty machine and the type of fault only according to the alarm of the PLC control system, without having to conduct a patrol inspection on the entire equipment group. At the same time, the PLC control system can also control the dry oil pump oil cup to supply less oil when it is less and more oil when it is more, ensuring that the oil quality is always good, will not deteriorate in the oil circuit, and will not cause blockage.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The present invention will be further described below in conjunction with the drawings and specific embodiments to help understand the content of the present invention. The methods used in the present invention are all conventional methods unless otherwise specified; the raw materials and devices used are all conventional commercially available products unless otherwise specified.

[0020] Embodiment:

[0021] As Figure 1 shown, the present invention provides an oil injection lubrication system for a tire vulcanizer, including a centralized lubrication system end 1100 and a plurality of vulcanizer ends 2100. The centralized lubrication system end 1100 conveys the lubricating oil in the oil storage tank 1 to the plurality of vulcanizer ends 2100. Each vulcanizer end 2100 is provided with a detection device 2 for detecting whether the oil volume is full, and the detection device 2 transmits a signal to the centralized lubrication system end 1100.

[0022] Further, the centralized lubrication system end 1100 includes a main oil pump 3, a main solenoid valve 4, a main oil pipe 5 and a PLC control system 6. The inlet of the main oil pump 3 is connected to the oil storage tank 1, the outlet of the main oil pump 3 is connected to the main oil pipe 5, the main solenoid valve 4 is installed on the main oil pipe 5, and the main solenoid valve 4 is electrically connected to the PLC control system 6.

[0023] Furthermore, the vulcanizer end 2100 includes a sub-oil pipe 7, a sub-solenoid valve 8, and a grease pump oil cup 9. One end of the sub-oil pipe 7 is communicated with the main oil pipe 5, and the other end is communicated with the grease pump oil cup 9. The sub-solenoid valve 8 is installed on the sub-oil pipe 7. The sub-solenoid valve 8 is electrically connected to the PLC control system 6. The PLC control system 6 can control the grease pump oil cup 9 to supply less oil and make up more oil, ensuring that the oil quality is always good, and the oil will not deteriorate in the oil circuit, nor will it cause blockage. The grease pump oil cup 9 is connected to the detection device 2.

[0024] Specifically, the lubricating oil entering the grease pump oil cup 9 is transported to each moving part in the vulcanizer through a grease distributor (not shown in the figure) and a connecting oil pipe (not shown in the figure).

[0025] Furthermore, the detection device 2 includes a pressing plate 21, a spring 22, a mounting seat 23, and a signal switch 24. The grease pump oil cup 9 is placed on the pressing plate 21. The mounting seat 23 is arranged below the pressing plate 21. The spring 22 is installed between the pressing plate 21 and the mounting seat 23. The signal switch 24 is fixedly installed at the middle position of the mounting seat 23. The signal switch 24 is signal-connected to the PLC control system 6.

[0026] In this embodiment, the number of the springs 22 is two, symmetrically distributed on both sides of the signal switch 24. The button trigger length on the signal switch 24 of each grease pump oil cup 9 matches the deformation range of the spring 22. The signal switch 24 in this embodiment adopts a normally closed contact that cuts off power when pressed and connects power when released, avoiding damage to the switch caused by long-term power connection, and at the same time being able to maintain the circuit.

[0027] Furthermore, both ends of the pressing plate 21 are bent upward to form an inverted trapezoid. Specifically, the pressing plate 21 is in the form of an oil receiving tray to prevent the grease pump oil cup 9 from leaking oil and polluting the equipment and the environment.

[0028] Furthermore, an iron plate 10 is fixedly installed on the top of the mounting seat 23, and the signal switch 24 is fixedly installed on the top of the iron plate 10. The iron plate 10 can further enhance the stability of the installation of the signal switch 24, ensure the normal operation of the signal switch 24, and at the same time enable the signal switch 24 to dissipate heat through the iron plate 10, ensuring that the working temperature of the signal switch 24 is always within the normal range, improving the stability and working life of the signal switch 24.

[0029] When the lubricating oil in the oil cup 9 of the dry oil pump is sufficient, it drives the pressure plate 21 to press downwards, causing the spring 22 to deform and compress. The pressure plate 21 presses the button of the signal switch 24, and the signal switch 24 transmits a signal to the PLC control system 6 through the signal switch control line 11 to close the sub-solenoid valve 8 and stop supplying oil to the oil cup 9 of the dry oil pump of this equipment. When there is no oil supply request for the oil cups 9 of the dry oil pumps of all vulcanizers (the oil supply request is judged by the signal of the signal switch 24), the PLC control system 6 gives a signal to close the main oil pump 3 and the main solenoid valve 4 and stop supplying oil to all vulcanizers.

[0030] This system is applicable to automatically lubricate and inject oil for a large number of vulcanizer equipment with the same structure and function and centrally installed in the same area and requiring regular lubrication.

[0031] The working principle of this embodiment is as follows:

[0032] First, install an oil storage tank 1 and a main oil pump 3 at one end of the middle trench of the vulcanizer equipment group, and the worker adds sufficient lubricating oil into the oil storage tank 1;

[0033] Second, erect a main oil pipe 5 above the middle trench of the vulcanizer equipment group. The main oil pipe 5 is connected to multiple sub-oil pipes 7 leading to the oil cups 9 of the dry oil pumps of each vulcanizer. If the number of vulcanizers is large and the conveying distance is far, a booster pump can be appropriately added to the oil circuit;

[0034] Third, install a PLC control system 6 at one end of the main oil pump 3;

[0035] Fourth, a sub-solenoid valve 8 for controlling the opening and closing of the oil circuit needs to be installed between each sub-oil pipe 7 and the inlet pipeline of the dry oil pump of each vulcanizer;

[0036] When it is necessary to inject oil and lubricate the moving parts in the vulcanizer, the PLC control system 6 controls the opening of the main oil pump 3 and the main solenoid valve 4 through the main control line 12. The main oil pump 3 transports the lubricating oil in the oil storage tank 1 into the main oil pipe 5. The lubricating oil in the main oil pipe 5 flows into each sub-oil pipe 7. The PLC control system 6 controls the corresponding sub-solenoid valve 8 to open through each sub-solenoid valve control line 13 (the number of sub-solenoid valves 8 to be opened can be controlled according to the actual oil injection needs), so that the lubricating oil in the sub-oil pipe 7 is injected into the oil cup 9 of the dry oil pump. The lubricating oil entering the oil cup 9 of the dry oil pump is transported to each moving part in the vulcanizer through the dry oil distributor and the connecting oil pipe.

[0037] When lubricating oil in the oil cup 9 of the dry oil pump is injected, a downward pressure is exerted on the pressure plate 21, causing the spring 22 to deform and compress, so that the pressure plate 21 presses on the button of the signal switch 24. At this time, the signal switch 24 transmits a signal to the PLC control system 6 through the signal switch control circuit 11. After receiving the signal, the PLC control system 6 closes the sub-solenoid valve 8 to stop supplying oil to the oil cup 9 of the dry oil pump of this equipment. When there is no oil supply request for the oil cups 9 of the dry oil pumps of all vulcanizers (the oil supply request is judged by the signal of the signal switch 24), the PLC control system 6 gives a signal to close the main oil pump 3 and the main solenoid valve 4 to stop supplying oil to all vulcanizers.

[0038] The oil injection lubrication system of this vulcanizer adopts automatic detection and control technology to timely detect the oil volume of the oil cups 9 of the dry oil pumps of each vulcanizer equipment and add oil as needed, which can save labor input, quantitatively inject oil into the oil cups 9 of the dry oil pumps according to the equipment requirements and maintenance cycles, shorten the maintenance cycle, and meet the equipment lubrication requirements; at the same time, it can detect whether there is leakage or oil circuit blockage in the lubrication system, reduce oil waste, and ensure the oil quality.
