Description
Technical field
The utility model belongs to sewing machine technique field, is related to a kind of detection device, particularly a kind of food tray of sewing machine
Oil mass detection device.
Background technology
Sewing machine is in high-speed cruising state during fabric is sutured, old in order to avoid the appearance abrasion of transmission parts
Change, it is necessary to be lubricated to transmission parts.Food tray is generally provided with existing sewing machine, there is oil pocket on food tray, will moisten
Lubricating oil is injected into oil pocket, then is noted lubricating oil by the oil pump on sewing machine and suctioned out out of oil pocket, and will by oil feed line
On the transmission parts that lubricating oil supply needs lubricate.On the one hand meat can not be passed through during lubricating oil is injected into food tray
Eye is clearly seen that the fluid liquid level in food tray, once misoperation causes lubricating oil injection is excessive will overflow out of food tray
Go out；The situation of lubricating oil reduction necessarily occurs in another aspect sewing machine in use, once the lubricating oil in food tray
When content is less than the oil mass needed for sewing machine work, sewing machine strenuous vibration is may result in, can if things go on like this cause sewing machine
Transmission parts serious wear, the service life of sewing machine are short.
At present, in order to avoid the excessive or very few situation of oil mass appearance in oil pocket, Chinese patent net disclose a kind of sewing
Machine oil amount detecting device (application number：201610248464.X), it includes the food tray equipped with oil pocket, further includes and is installed in oil pocket
Pillar, change in oil pocket and with fluid height of liquid level in oil pocket and the float that fluctuates and be installed on float
By sensing unit, is equipped with annular seal space in the pillar, is installed with the annular seal space for sensing the sensor by sensing unit.
Although above-mentioned sewing machine oil amount detecting device several timely can be monitored the oil mass in oil pocket, sensor is set
Put in the annular seal space on pillar, it is close after aging occurs in the seal on pillar since pillar is arranged in oil pocket
Envelope chamber is no longer on sealing state, and then the lubricating oil in oil pocket is entered in annular seal space, causes sensor to be immersed in lubricating oil
In cause to damage, and the complicated of the device, component number are more, of high cost, it has not been convenient to are installed in oil pocket.
The content of the invention
The purpose of this utility model is that there are the above problem for existing technology, it is proposed that a kind of food tray oil of sewing machine
Amount detecting device, the technical problem that the utility model solves are：How to simplify food tray oil mass detection device structure and effectively
Isolation lubricating oil and sensor avoid the sensor from being soaked by lubricating oil.
The purpose of this utility model can be realized by following technical proposal：A kind of food tray oil mass detection dress of sewing machine
Put, the sewing machine includes the food tray with oil pocket, and the food tray oil mass detection device is arranged in oil pocket, it is characterised in that
The bottom surface of the oil pocket is equipped with boss, and mounting groove is offered along the axial direction of boss on the outer bottom of the food tray；The food tray
Oil mass detection device includes oil float mark and is arranged in mounting groove and can sense the sensor that oil float is marked on oily intracavitary locations, described
The fluid height of liquid level change in the surface of boss and with oil pocket of oil float mark fluctuates on the axis direction of boss.
The height and position that the utility model is marked on by sensor sensing oil float in oil pocket changes to judge in oil pocket
The height of fluid liquid level, when oil pocket inner fluid liquid level is less than the upper surface of boss, oil float mark is contacted with the upper surface of boss, this
When oil float mark and sensor it is closest, sensor output alarm signal warning user's oil pocket in lubricants capacity it is few, it is necessary to
Injection lubricating oil in toward oil pocket, and set boss to have when ensure that sensor output alarm signal in oil pocket also with a certain amount of
Lubricating oil.Mounting groove is located at outside oil pocket, by the way that sensor is arranged in mounting groove so that sensor also is located at outside oil pocket, is passed
Sensor and the lubricating oil in oil pocket are completely isolated, avoid the immersion sensor of the lubricating oil in oil pocket and cause sensor degradation, into
And improve the service life of sensor.
In a kind of food tray oil mass detection device of above-mentioned sewing machine, the food tray oil mass detection device further includes fixation
Case on boss upper surface, the case is upper end closed, the cylinder of lower ending opening, and the oil float mark is arranged on case
In inner cavity, connection oil pocket and the oil-through-hole of case inner cavity are offered on the side wall of the case lower end.Moisten when toward injection in oil pocket
During lubricating oil, when fluid liquid level rises above the height of boss, lubricating oil enters through oil-through-hole and enters case
So that oil float puts on floating, the distance between oil float mark and sensor increase in inner cavity, lubricating oil, which is persistently injected into oil pocket, to be caused
Oil float target upper end and the top contact of the inner cavity of case, at this time oil float mark and maximum, the sensor with the distance between sensor
Possesses enough lubricating oil in output alarm signal warning user's oil pocket, avoiding injecting excessive lubricating oil causes to overflow.
In a kind of food tray oil mass detection device of above-mentioned sewing machine, the upper end of the case offers through hole.So that
The gas that oil float is marked in uphill process in case can be discharged effectively, ensure that oil float mark can smoothly float.
In a kind of food tray oil mass detection device of above-mentioned sewing machine, the upper surface of the boss is equipped with protrusion, institute
State raised extend in the inner cavity of case.When the fluid liquid level in oil pocket is less than the upper surface of boss, oil float target lower face
With raised upper-end contact so that there is gap, toward the interior injection profit of oil pocket between oil float target lower face and the upper surface of boss
During lubricating oil, the lubricating oil entered in the inner cavity of case smoothly holds up oil float mark by the gap.
In a kind of food tray oil mass detection device of above-mentioned sewing machine, the lateral wall of the case lower end is equipped with installation
Plate, the installing plate are fixed on boss by fastener.Case is fixed on boss by installing plate, which is screw
Or bolt, case installation, convenient disassembly.
In a kind of food tray oil mass detection device of above-mentioned sewing machine, the oil float mark includes the internal housing hollowed out,
The bottom surface of the housing is equipped with sensing element.The inside of housing is hollowed out effectively alleviating the weight of housing afterwards, ensure that
Oil float target volume when oil float mark is floated on fluid in fluid is less so that oil float target bottom surface is close proximity to fluid liquid
Face, increases the distance between sensing element and sensor so that fluid liquid level during sensor output alarm signal in oil pocket
Highly maximize.
In a kind of food tray oil mass detection device of above-mentioned sewing machine, the sensing element is magnet, the sensor
For Hall sensor.The small, light-weight of Hall sensor, high sensitivity and easy for installation.
Compared with prior art, the food tray oil mass detection device of the sewing machine of the utility model has the following advantages：1st, lead to
Cross sensor being arranged in mounting groove and make it that sensor and the lubricating oil in oil pocket are completely isolated, avoid the lubrication in oil pocket
Oil immersion bubble sensor causes sensor degradation, and then improves the service life of sensor；2nd, the structure of the utility model is more
