Abstract
Bearing breakage can be resulted from different shearing stresses of different plastics and excessive feeding and other human factors during extruding of plastics, and the problems of accumulated bulks and poor quality of extruded plastics and the like can be caused in case of untimely finding of bearing breakage. The utility model aims at the bearing breakage problem of plastic extruders to provide a bearing breakage alarm for a plastic extruder, which is capable of well monitoring operation states of a bearing. When the bearing is undamaged, an electrode A, an electrode D, an alarm, an electrode C, an electrode B and the inner wall of the bearing form a conductive loop, and the alarm gives no alarm. When the bearing is broken, cracked or the like, the conductive loop is cut off or resistance is increased sharply, and the alarm gives an alarm while the plastic extruder is stopped under control of a control circuit.
Description
Technical field
The utility model relates to the plastic extruder servicing unit, relates in particular to a kind of plastic extruder bearing breaking alarm.
Background technology
Extrude in the production link in plastic processing; Since different plastics shear stress be not quite similar; When reaching, overcharge artificially wait some other reasons that the problem of bearing breaking can take place; If, pile up problems such as material and extrusion plastic degradation if find the untimely bulk that then can cause in case occur.Therefore the alarm device of bearing breaking is very necessary.
The utility model content
The utility model provides a kind of plastic extruder bearing breaking alarm to the breakage problem of plastic extruder bearing, comprises bearing, electrode A, electrode B, electrode C, electrode D, lead, and wherein, electrode A links to each other with bearing inner wall with electrode B and is communicated with; Electrode C is connected with the bearing end with electrode D, and electrode C and electrode D and bearing inner wall insulation; Electrode A, electrode D, alarm, electrode C, electrode B, bearing inner wall constitute the galvanic circle.There are power supply, control circuit in alarm inside.
The plastic extruder bearing breaking alarm that the utility model provides can well be monitored the duty of bearing.When bearing was intact, electrode A, electrode D, alarm, electrode C, electrode B, bearing inner wall constituted the galvanic circle, and alarm is not reported to the police; When problems such as bearing appearance fracture, crackle, galvanic circle fracture or resistance sharply increase, and alarm is reported to the police, and the plastic extruder of control circuit control is simultaneously shut down.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1, bearing, 2, electrode A, 3, electrode B, 4, electrode C material, 5, electrode D, 6, lead
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of the utility model, comprises 1 bearing, 2 electrode A, 3 electrode B, 4 electrode C, 5 electrode D, 6 leads, wherein, 2 electrode A link to each other with 1 bearing inner wall with 3 electrode B and together with; 4 electrode C are connected with 1 bearing end with 5 electrode D, and 4 electrode C and 5 electrode D and the insulation of 1 bearing inner wall; 2 electrode A, 5 electrode D, alarm, 4 electrode C, 3 electrode B, 1 bearing inner wall constitute the galvanic circle.There are power supply, control circuit in alarm inside.When 1 bearing was intact, 2 electrode A, 5 electrode D, alarm, 4 electrode C, 3 electrode B, 1 bearing inner wall constituted the galvanic circle, and alarm is not reported to the police; When problems such as 1 bearing appearance fracture, crackle, galvanic circle fracture or resistance sharply increase, and alarm is reported to the police, and the plastic extruder of control circuit control is simultaneously shut down.The plastic extruder bearing breaking alarm that the utility model provides can well be monitored the duty of bearing.
More than show and described basic principle of the utility model and the advantage of principal character and the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; That describes in the foregoing description and the specification just explains principle of the present invention; Under the prerequisite that does not break away from spirit and scope of the invention, the present invention also has various changes and modifications, and these variations and improvement all fall in the scope of the invention that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
Claims (2)
