The terms used in the description of this specification are only for the purpose of describing specific embodiments and are not intended to limit the present utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0023] To solve the above problems, please refer to Figures 1 to 2 , the present utility model provides a multi-channel rotating shaft stop alarm device, which is applied to a mixing device and includes a detection structure 1, an alarm structure 2, and a control structure 3. The detection structure 1 is used to detect the operating state of the mixing device. The detection structure 1 includes a measured part 11 and a detection part 12. The measured part 11 is arranged on the periphery of the linkage rotating shaft 4 of the mixing device. The detection part 12 is used to sense the rotation state of the measured part 11. The alarm structure 2 is used to give out a sound and light warning according to the sensing structure of the detection structure 1. The control structure 3 is electrically connected to a plurality of the detection structures 1 and the alarm structure 2. Among them, the detection part 12 and the measured part 11 are continuously connected or disconnected to form an electrical signal. The control structure 3 receives the electrical signal and controls the corresponding alarm structure 2 to give out a sound and light warning according to the electrical signal. Among them, the measured part 11 is an iron metal block, and the detection part 12 is a metal sensor. Within the measurable range of the detection part 12, the measured part 11 rotates with the linkage rotating shaft 4. When the measured part 11 rotates to the shortest distance from the detection part 12, the detection part 12 obtains the information that the measured part 11 has passed, and uses this as the basis for judging whether the mixing device has stopped rotating for a long time. The linkage rotating shaft 4 is a coupling, and the coupling is arranged outside the mixing device and connected to the mixing shaft of the mixing device. The coupling has the same rotation speed as the mixing device. The setting of the coupling facilitates the staff to monitor the rotation of the mixing shaft of the mixing device outside the mixing device.

[0024] In an alternative embodiment, as Figure 1 shown, the detection range of the detection part 12 is less than 5 mm. Within this detection range, the detection part 12 has a good accuracy rate.

[0025] In an alternative embodiment, as Figure 1 and Figure 2 shown, the control structure 3 includes a programmable controller 31 and an intermediate relay 32. The programmable controller 31 is electrically connected to the detection member 12 and drives the intermediate relay 32 to control the alarm structure 2 to give a warning. The programmable controller 31, as a signal input / output processor, can, through the parameters of the device program, monitor the stoppage of a stirring device at any rotational speed within the range of 1 revolution per minute to 100 revolutions per minute. The programmable controller 31 has a plurality of input ports, and each group of detection structures 1 is correspondingly connected to an input port. Among them, the intermediate relay 32 has a plurality of normally open contacts, and each normally open contact is connected to a group of alarm structures 2. By using identification or numbering, the alarm structures 2 corresponding to each stirring device are distinguished.

[0026] In an alternative embodiment, as Figure 1 and Figure 2 shown, the alarm structure 2 includes an indicator light 21 and an audible and visual alarm 22. The indicator light 21 is used to indicate the location where the abnormality occurs, and the audible and visual alarm 22 is used to give a warning sound. Specifically, each stirring device is correspondingly provided with a group of detection structures 1, and each group of detection structures 1 corresponds to a group of alarm structures 2. When one of the stirring devices stops rotating, after the corresponding detection structure 1 senses its stop, it transmits the abnormal information to the control structure 3. The control structure 3 further controls the indicator light 21 and the audible and visual alarm 22 to operate, reminding the staff that the stirring device has a stoppage abnormality and to go for processing. It is not necessary for the staff to patrol constantly and manually monitor the equipment abnormality all the time. Further, the indicator light 21 is provided with identification or numbering, so that the staff can quickly distinguish which stirring device has an abnormality, improving the work efficiency of the staff and having a high accuracy rate.

[0027] In an alternative embodiment, as Figure 1 shown, the detection structure 1 further includes a mounting bracket 13. One end of the mounting bracket 13 is connected to the detection member 12, and the sensing end of the detection member 12 faces the linkage rotating shaft 4. The other end is connected to the ground. A limiting hole is opened at one end of the mounting bracket 13 away from the ground, and the detection member 12 is passed through the limiting hole. The direction of the detection member 12 is adjusted so that the sensing end of the detection member 12 faces the linkage rotating shaft 4, facilitating the detection member 12 to sense the state of the measured member 11. Among them, the detection member 12 can be fixedly connected to the mounting bracket 13 by welding, improving the connection strength between the detection member 12 and the mounting bracket 13. Further, the mounting bracket 13 can also be provided with a clamping member for clamping the detection member 12, facilitating the adjustment of the position of the detection member 12 so that when the measured member 11 approaches the detection member 12, it is within the detectable range of the detection member 12.

[0028] In an alternative embodiment, as Figure 1 shown, the DUT 11 is detachably connected to the linkage rotating shaft 4. The linkage rotating shaft 4 is provided with a slot, and one end of the DUT 11 is inserted into the slot. Specifically, one end of the DUT 11 is provided with an external thread, and the inner wall of the slot is provided with an internal thread. The DUT 11 is connected to the linkage rotating shaft 4 by means of a threaded connection, which facilitates the replacement of the DUT 11. Further, the DUT 11 can also be connected to the linkage rotating shaft 4 by welding to improve the connection strength between the DUT 11 and the linkage rotating shaft 4.

[0029] Working principle: When the rotating shaft stops rotating, the DUT 11 stops at any position. The detecting element 12 is in contact with or disconnected from the DUT 11 for a long time. The detecting element 12 transmits this information to the programmable controller 31. The programmable controller 31 drives the intermediate relay 32 to actuate and close, so that the corresponding normally open contact closes. Further, it drives the indicator light 21 and the audio-visual alarm to emit light and sound. The indicator light 21 indicates the number of the stopped stirring equipment, which is convenient for the operator to check and handle.

[0030] In the embodiment of the present invention, by providing this multi-channel rotating shaft stop alarm device, the rotation condition of the stirring shaft of the stirring equipment is monitored in real time. When the stirring shaft stops rotating, the control structure 3 controls the alarm structure 2 to issue a warning according to the contact condition between the detecting element 12 and the DUT 11, quickly reminding the staff of the occurrence of the abnormality and indicating the abnormal position, which is convenient for the staff to quickly go to detect and handle. At the same time, by monitoring the stirring state of the stirring equipment in real time, the process production efficiency can be improved and the product quality can be guaranteed. It is possible to monitor multiple stirring equipments simultaneously, with strong adaptability.

[0031] In the drawings of this embodiment, the same or similar reference numerals correspond to the same or similar components. In the description of the present invention, it should be understood that if there are terms such as "upper", "lower", "left", "right", etc. indicating the orientation or positional relationship, they are based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the terms describing the positional relationship in the drawings are only for illustrative purposes and cannot be construed as a limitation of the present invention. For those of ordinary skill in the art, the specific meanings of the above terms can be understood according to specific circumstances.
