[0014] In the figure, 1 is a machine body, 2 is a feeding disc, 3 is a rotating shaft, 4 is a speed reducer, 5 is a motor, 6 is a belt, 7 is a detection block, 8 is a proximity switch, 9 is a connecting frame, 10 is a controller, 11 is an alarm, and 12 is a rotating speed sensor. DETAILED DESCRIPTION

[0015] The utility model will be explained in detail below in combination with the drawings:

[0016] As Figure 1 shown, a disc feeder fault detection device, including machine body 1, machine body 1 is equipped with the feeding disc 2 that is horizontally set, the feeding disc 2 top is equipped with the hopper, through the rotation of feeding disc 2, the material in the hopper can be transported to the conveyer belt, the bottom of feeding disc 2 is fixed with the rotating shaft 3 for driving feeding disc, the rotating shaft 3 is vertically arranged, the bottom end of rotating shaft 3 is connected with speed reducer 4, machine body 1 is equipped with motor 5, speed reducer 4 and motor 5 are driven connection through belt 6, the connection installation mode of feeding disc 2 and rotating shaft 3, speed reducer 4 and motor 5 are all conventional disc feeder installation mode, the lower surface of feeding disc 2 is fixed with detection block 7, detection block 7 can rotate with feeding disc 2, the lower side of detection block 7 is equipped with proximity switch 8, machine body 1 is equipped with connecting frame 9, proximity switch 8 is installed on connecting frame 9, when detection block 7 rotates to the upper side of proximity switch 8, can be detected by proximity switch 8, proximity switch 8 is connected with controller 10, controller 10 is connected with alarm 11, but when the feeding disc 2 occurs deviation, proximity switch 8 cannot detect detection block 7, that is, deviation fault can be found in time, when the phenomenon of plugging appears, feeding disc 2 cannot rotate, also can make proximity switch 8 cannot detect detection block 7, in addition, controller 10 is also connected with motor 5, when fault occurs, can control motor 5 to stop running in time, and control alarm 11 to alarm simultaneously, prompt operating personnel to handle in time.

[0017] Machine body 1 is equipped with rotating speed sensor 12 for detecting the rotating speed of rotating shaft 3, rotating speed sensor 12 is connected with controller 10, when rotating speed sensor 12 detects that the rotating speed of rotating shaft 3 does not match the rotating speed of motor 5, it indicates that the jamming and sliding fault occurs, and controller 10 controls motor 5 to customize operation.

[0018] The use mode of the utility model is as follows:

[0019] When the disc feeder is in normal operation, the rotating shaft 3 drives the feeding disc 2 to rotate, and the feeding disc 2 drives the detection block 7 to rotate, and the detection block 7 can be detected by the proximity switch 8 every rotation, when the disc feeder fails, the feeding disc 2 deviates, the detection block 7 deviates with it and cannot be detected by the proximity switch 8, or the feeding disc 2 cannot rotate due to blockage, the detection block 7 also cannot be detected by the proximity switch 8, at this time, the proximity switch 8 sends a signal to the controller 10, the controller 10 controls the motor 5 to stop running, and controls the alarm 11 to send an alarm signal, prompting the operator to handle the fault in time, if the feeding disc 2 appears the phenomenon of jamming and sliding, the rotating shaft 3 appears jamming in the rotating process, the rotating speed slows down, the rotating speed of the rotating shaft 3 and the rotating speed of the motor 5 are not matched, the rotating speed sensor 12 sends a signal to the controller 10, the controller 10 controls the motor 5 to stop running, and controls the alarm 11 to send an alarm signal.

[0020] The device can accurately detect the fault of the disc feeder in time, so that the operator can quickly handle it.
