The needle assembly typically comprises a needle bar, a needle plate fixedly mounted on the needle bar, and a plurality of needles arranged on the needle plate (the needles are typically distributed evenly on the needle plate), wherein the needle bar is connected to the push rod. When the transmission shaft assembly rotates, the eccentric wheels on the transmission shaft assembly are driven to rotate, the eccentric wheels drive the needle assembly to do reciprocating linear motion through the rocker arms and the push rods, repeated needling is conducted on the fiber web, and the fluffy fiber web is solidified through the needling effect.
Generally, the higher the number of needle punching times per unit time (i.e., the higher the needle punching frequency) of the needle punching mechanism, the higher the needle punching density (the number of needle punching per unit area), the better the quality of the obtained web, and the higher the production efficiency.

The main shaft bearing of the needling mechanism can generate heat in the high-speed needling process, lubricating oil is needed to be used for lubricating, the main shaft bearing is in a good lubricating effect state, the heat productivity is reduced, and meanwhile, the heat is dissipated by utilizing the flowing of the lubricating oil, however, the existing lubricating mode can not supply proper amount of lubricating oil to each main shaft bearing according to the actual operation condition, the lubricating and heat dissipating effects on the main shaft bearing are not ideal enough, the service life of the main shaft bearing is short, and the main shaft bearing is difficult to find by workers in time when being damaged, so that the needling machine is damaged more greatly.
Disclosure of Invention
The technical problem to be solved by the invention is to provide an automatic lubricating system of a needling machine, which not only can automatically supply lubricating oil to each main shaft bearing, but also can detect the temperature value of each main shaft bearing in real time and accordingly control the oil supply quantity to each main shaft bearing, so that each main shaft bearing can keep the optimal lubricating and heat dissipation effects. The technical scheme is as follows:
the utility model provides a needle loom's automatic lubrication system, includes headstock, main shaft and a plurality of main shaft bearing, and the main shaft passes through the rotatable installation of each main shaft bearing in the cavity of headstock, its characterized in that: the automatic lubricating system also comprises an oil tank, an oil delivery pump, a plurality of oil supply joints for supplying lubricating oil to each main shaft bearing, a control device and a plurality of temperature sensors for detecting the temperature of each main shaft bearing, wherein an oil inlet of the oil delivery pump is communicated with the cavity of the oil tank through a first oil delivery pipe, an inlet of each oil supply joint is respectively communicated with an oil outlet of the oil delivery pump through a second oil delivery pipe, and the second oil delivery pipe is provided with an electromagnetic switch valve; each temperature sensor is respectively and electrically connected with the corresponding input end of the control device, and the oil transfer pump and each electromagnetic switch valve are respectively and electrically connected with the corresponding output end of the control device; the control device detects the actual temperature value of the corresponding main shaft bearing through each temperature sensor, compares the actual temperature value with the upper limit value of the temperature range value set in the control device, and outputs a control signal according to the comparison result to control the oil transfer pump and each electromagnetic switch valve to be in an open or closed state so as to control the oil supply amount to each main shaft bearing and enable each main shaft bearing to be in the set temperature range value.
Typically, there is one oil supply connection and one temperature sensor for each spindle bearing.
In the automatic lubricating system, lubricating oil is filled in an oil tank; when the oil delivery pump and each electromagnetic switch valve are in an open state, lubricating oil in the oil tank flows through the first oil delivery pipe, the oil delivery pump and each second oil delivery pipe in sequence under the pumping of the oil delivery pump to enter each oil supply joint, and the lubricating oil is supplied to each main shaft bearing for lubrication and heat dissipation; the control device detects the actual temperature value of the corresponding main shaft bearing through each temperature sensor, compares the actual temperature value with the upper limit value of the temperature range value set in the control device, and outputs a control signal according to the comparison result to control the oil transfer pump and each electromagnetic switch valve to be in an open or closed state so as to control the oil supply amount to each main shaft bearing, so that each main shaft bearing keeps the optimal lubricating and heat dissipation effects, and each main shaft bearing is in the set temperature range value.
In the working process of the needling machine, the control device enables the oil transfer pump to keep an opening state and controls each electromagnetic switch valve to be opened for a certain time at intervals and then closed: when each electromagnetic switch valve is in an open state, lubricating oil in the oil tank flows through the first oil conveying pipe, the oil conveying pump and each second oil conveying pipe in sequence under the pumping of the oil conveying pump to enter each oil supply joint, and the lubricating oil is quantitatively supplied to the corresponding main shaft bearing by each oil supply joint; when each electromagnetic switch valve is in a closed state, each oil supply joint stops supplying lubricating oil to the corresponding main shaft bearing, so that the lubricating oil is regularly and quantitatively supplied to each main shaft bearing, each main shaft bearing is in a set temperature range value, and each main shaft bearing keeps the optimal lubricating and heat dissipation effects. If the temperature of the main shaft bearing rises abnormally (namely the actual temperature value is detected to exceed the upper limit value of the set temperature range value), the control device controls the electromagnetic switch valve on the second oil pipeline corresponding to the main shaft bearing to be in a continuous opening state (other electromagnetic switch valves are still closed after being opened for a certain time), and the main shaft bearing is subjected to rapid heat dissipation and cooling until the actual temperature value of the main shaft bearing returns to the set temperature range value. The temperature range set in the control device is set by taking into account the requirement that the temperature rise range does not exceed 30 ℃ when the main shaft bearing is normally operated (i.e. the temperature of the main shaft bearing is at most 30 ℃ higher than the ambient temperature) and the maximum temperature of the main shaft bearing itself does not exceed 80 ℃, for example, in the case of an ambient temperature of 30 ℃, the set temperature range may be 30 ℃ to 60 ℃ and the upper limit value of the temperature range is 60 ℃.

In the working process of the needling machine, lubricating oil flows into the mounting groove of the bearing seat through an outlet of the oil supply joint and lubricates a main shaft bearing in the mounting groove; because the main shaft bearing and the bearing seat are made of metal materials and have good heat conductivity, the control device can detect the temperature value of the bearing seat through the temperature sensor to obtain the actual temperature value of the corresponding main shaft bearing, and then the opening duration of the corresponding electromagnetic switch valve is controlled according to the actual temperature value.

A worker can control parameters such as the opening and closing of the oil transfer pump and each electromagnetic switch valve, the opening duration of each electromagnetic switch valve, the set temperature range value and the like through a human-computer interface, and the human-computer interface can display the actual temperature value of each main shaft bearing and whether the main shaft bearing is in an abnormal state or not in real time. In the working process of the needling machine, if the actual temperature value of the main shaft bearing is detected to exceed the upper limit value of the set temperature range value, the control device can control the electromagnetic switch valve on the second oil pipeline corresponding to the main shaft bearing to be in a continuous opening state, and simultaneously, a human-computer interface alarms (can alarm in the forms of flashing, sound and the like to warn workers) to warn the workers that the temperature of the main shaft bearing rises abnormally; then, if the temperature sensor detects that the temperature of the main shaft bearing returns to the set temperature range value, the control device controls the corresponding electromagnetic switch valve to be closed and enables the human-computer interface to stop alarming; if the temperature sensor detects that the temperature of the main shaft bearing does not drop (the temperature is kept unchanged or rises), the main shaft bearing is damaged, the control device gives an alarm continuously through a human-computer interface, maintenance personnel are reminded to handle the main shaft bearing in time, exception removal is waited, and larger damage is avoided.
In another preferred scheme, the automatic lubricating system further comprises a plurality of alarms, the alarms are in the same number with the main shaft bearings and are in one-to-one correspondence, and each alarm is electrically connected with the corresponding output end of the control device. If the actual temperature value of the main shaft bearing is detected to exceed the upper limit value of the set temperature range value, the control device controls the electromagnetic switch valve on the second oil pipeline corresponding to the main shaft bearing to be in a continuous opening state, and meanwhile, the corresponding alarm gives an alarm to warn a worker that the temperature of the main shaft bearing rises abnormally; then, if the temperature sensor detects that the temperature of the main shaft bearing returns to the set temperature range value, the control device controls the corresponding electromagnetic switch valve to be closed and enables the corresponding alarm to stop alarming; if the temperature sensor detects that the temperature of the main shaft bearing does not drop (the temperature is kept unchanged or rises), the main shaft bearing is damaged, the control device gives an alarm continuously to remind maintenance personnel to process in time, wait for abnormal removal and avoid larger damage.
Generally, the control device adopts a PLC controller or a single chip microcomputer. The worker can select the optimal oil supply amount and oil supply time through experiments, corresponding working parameters (such as the opening duration of each electromagnetic switch valve, the set temperature range value and the like) are input into the control device in advance, and the control device controls the switch of each electromagnetic switch valve in the working process of the needling machine so as to achieve the optimal lubricating and heat dissipation effects.
In a preferable scheme, the automatic lubricating system further comprises a plurality of push rod guide sleeve seats and an oil return pump; each push rod guide sleeve seat is sequentially arranged along the axial direction of the main shaft, each push rod guide sleeve seat comprises a push rod and a guide sleeve, each guide sleeve comprises an outer guide sleeve seat and an inner guide sleeve, the outer guide sleeve seats are fixedly arranged on the main shaft box, an installation cavity with an upper opening and a lower opening is formed in each outer guide sleeve seat, each inner guide sleeve is arranged in the installation cavity of each outer guide sleeve seat, the outer wall of each inner guide sleeve is fixedly connected with the inner wall of each outer guide sleeve seat, and each inner guide sleeve is internally provided with a guide hole in an up-and-down direction; the push rod is arranged in a guide hole of the inner guide sleeve, an oil storage gap is formed between the outer wall of the push rod and the inner wall of the guide hole, and an oil seal cover is arranged at the lower end of the outer guide sleeve seat; an oil storage tank is arranged on the inner wall of the upper part of the guide hole, and an annular groove extending along the circumferential direction of the inner wall of the middle part of the guide hole is arranged on the inner wall of the middle part of the guide hole; the upper end opening of the guide hole is communicated with the bottom of the cavity of the spindle box, an oil return opening is formed in the side wall of the outer guide sleeve seat and communicated with the lower end of the oil storage gap, the oil return opening is communicated with the cavity of the oil tank through an oil return pipe, and an oil return pump is installed on the oil return pipe.
In the push rod guide sleeve seat, an oil seal cover is used for sealing the lower end of the oil storage gap, so that lubricating oil cannot leak from the lower end of the outer guide sleeve seat; through set up annular groove at the middle part inner wall of guiding hole, can form the annular oil storage chamber that is used for saving lubricating oil between the outer wall of push rod and annular groove inner wall. In the working process of the needling machine, redundant lubricating oil lubricated for each main shaft bearing can drop to the bottom of a cavity of a main shaft box and is stored (the oil level of the lubricating oil in the main shaft box is generally slightly higher than the upper end opening of a guide hole), the lubricating oil in the main shaft box can enter an oil storage tank from the upper end opening of the guide hole and is refilled into an annular oil storage cavity and an oil storage gap below the annular oil storage cavity, a lubricating oil layer is formed between the inner wall of the guide hole and the outer wall of a push rod, and the lubricating oil flowing out of an oil return opening flows back into the oil tank through an oil return pipe so as to realize the purposes of recycling and cooling the lubricating oil; the contact area between the push rod and the inner guide sleeve can be reduced by arranging the annular groove, so that the friction force between the push rod and the inner guide sleeve is reduced, the heat productivity generated by friction in the process of up-and-down reciprocating motion of the push rod in the inner guide sleeve can be effectively reduced, and the up-and-down reciprocating motion frequency of the push rod can be increased. In the process that the push rod moves downwards along the guide hole of the inner guide sleeve, the annular step at the joint of the lower side groove wall of the annular groove and the inner wall of the lower part of the guide hole forms an oil retaining ring, a large amount of lubricating oil driven by the push rod can be blocked, most of the lubricating oil is left in the annular oil storage cavity, only a small amount of lubricating oil is filled in an oil storage gap below the annular oil storage cavity, and therefore the situation that oil leakage occurs due to overlarge pressure at the oil seal position caused by the fact that the excessive lubricating oil is brought to the oil seal position by the push rod can be avoided.
In a more preferable scheme, the guide hole is a circular through hole, the annular groove is a circular groove, and the center line of the annular groove coincides with the center line of the guide hole.
In a more preferable scheme, the upper end of the guide hole of the inner guide sleeve is provided with a round table-shaped opening with a large upper part and a small lower part, a gap between the top of the inner wall of the round table-shaped opening and the push rod forms an oil inlet, and the oil inlet is communicated with the upper end of the oil storage tank.

The following briefly describes the working principle of the automatic lubricating system:
the worker can select the optimal oil supply amount and oil supply time through experiments, corresponding working parameters (such as the opening time of each electromagnetic switch valve 43, a set temperature range value and the like) are input into the PLC 6 through the human-machine interface 11 in advance, the PLC 6 controls the opening time of each electromagnetic switch valve 43 in time in the working process of the needling machine so as to achieve the optimal lubricating and heat dissipation effects, and the human-machine interface 11 can display the actual temperature value of each main shaft bearing 3 and whether the main shaft bearing is in an abnormal state or not in real time. The temperature rise range of the main shaft bearing 3 is usually required to be not more than 30 ℃ when the main shaft bearing 3 is operated (i.e. the temperature of the main shaft bearing 3 is at most 30 ℃ higher than the ambient temperature), and the maximum temperature of the main shaft bearing 3 itself is not more than 80 ℃, and the temperature range value set in the PLC controller 6 is set as required, for example, in the case where the ambient temperature is 30 ℃, the temperature range value may be set to 30 ℃ to 60 ℃ and the upper limit value of the temperature range value is 60 ℃.
In the working process of the needling machine, the PLC 6 enables the oil transfer pump 4 to keep an opening state, and controls each electromagnetic switch valve 43 to be opened for a certain time at intervals and then closed: when each electromagnetic switch valve 43 is in an open state, the lubricating oil in the oil tank flows through the first oil delivery pipe 41, the oil delivery pump 4 and each second oil delivery pipe 42 in sequence under the pumping of the oil delivery pump 4 to enter each oil supply joint 5, and the lubricating oil is quantitatively supplied to the corresponding main shaft bearing 3 by each oil supply joint 5; when each electromagnetic switch valve 43 is in a closed state, each oil supply joint 5 stops supplying lubricating oil to the corresponding main shaft bearing 3, so that the lubricating oil is regularly and quantitatively supplied to each main shaft bearing 3, each main shaft bearing 3 is in a set temperature range value, and each main shaft bearing 3 keeps the optimal lubricating and heat dissipation effect. If the temperature of the main shaft bearing 3 rises abnormally (namely the actual temperature value is detected to exceed the upper limit value of the set temperature range value), the PLC 6 controls the electromagnetic switch valve 43 on the second oil pipeline 42 corresponding to the main shaft bearing 3 to be in a continuous opening state (other electromagnetic switch valves 43 are still closed after being opened for a certain time), the main shaft bearing 3 is subjected to rapid heat dissipation and cooling, meanwhile, the man-machine interface 11 is made to give an alarm (the alarm can be given in the forms of flashing, sound and the like to warn a worker, the worker is alerted that the temperature of the main shaft bearing 3 rises abnormally, the abnormality is waited to be eliminated, and larger damage is avoided; until the actual temperature value of the main shaft bearing 3 returns to the set temperature range value, and the human-computer interface 11 stops alarming.
In the working process, redundant lubricating oil lubricated for each spindle bearing 3 can drip to the bottom of the cavity of the spindle box 1 and is stored (the oil level of the lubricating oil in the spindle box 1 is generally slightly higher than that of the oil inlet 8203), the lubricating oil in the spindle box 1 can enter the oil storage tank 8222 from the oil inlet 8203 and is refilled into the annular oil storage cavity 8202 and an oil storage gap 8201 below the annular oil storage cavity 8202, a lubricating oil layer is formed between the inner wall of the guide hole 8221 and the outer wall of the push rod 81, and the lubricating oil flowing out of the oil return port 8212 flows back into the oil tank through an oil return pipe so as to achieve the purposes of recycling and cooling the lubricating oil; the contact area between the push rod 81 and the inner guide sleeve 822 can be reduced by arranging the annular groove 8223, so that the friction force between the push rod 81 and the inner guide sleeve 822 can be reduced, the heat productivity generated by friction in the process of up-and-down reciprocating motion of the push rod 81 in the inner guide sleeve 822 can be effectively reduced, and the up-and-down reciprocating motion frequency of the push rod 81 can be increased. In the process that the push rod 81 moves downwards along the guide hole 8221 of the inner guide sleeve 822, the annular step at the joint of the lower side groove wall of the annular groove 8223 and the lower inner wall of the guide hole 8221 forms an oil baffle ring, so that a large amount of lubricating oil driven by the push rod 81 can be blocked, most of the lubricating oil is remained in the annular oil storage cavity 8202, and only a small amount of lubricating oil is filled in an oil storage gap 8201 below the annular oil storage cavity 8202, so that the oil leakage caused by overlarge pressure at the oil seal position due to the fact that the excessive lubricating oil is brought to the oil seal position by the push rod 81 can be avoided, the lubricating oil is effectively prevented from polluting a needle plate and a non-woven product, the normal production of a needling mechanism cannot be greatly influenced, the production efficiency of the needling machine can be improved due to no need of stopping for maintenance, and the maintenance cost of the needling machine is reduced.
