[0002] The dust removal system of cigarette companies generally uses bag dust collectors, which mainly use dust removal fans to drive bag dust removal equipment. The dust removal fans are mainly powered by dust removal motors. The bearings of dust removal motors will heat up or vibrate more during long-term use. When the fault worsens, it will cause serious equipment failures such as motor bearing damage and motor burning, affecting the normal operation of the entire cigarette equipment.
[0003] Therefore, monitoring the temperature and vibration changes of the motor bearings has become an important detection item for controlling the operation of the dust removal motor. The existing abnormal detection methods of dust removal motors all require the addition of motor temperature and vibration monitoring. Therefore, special dust removal motors must be purchased to reserve the assembly positions of temperature control sensors and vibration sensors, which brings unnecessary cost increases and also requires the replacement and assembly of new motors.
[0004] For the traditional dust removal motors that have been used, the motor bearing end cover needs to be additionally processed in order to collect internal temperature changes. However, through actual testing, it is found that installing the detection device on the bearing end not only requires reprocessing of the bearing end cover, but also affects the sealing of the bearing end cover.

[0022] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be interpreted as limiting the present invention.
[0023] The utility model proposes an embodiment of a detachable temperature and vibration integrated detection device for a dust removal motor. Specifically, Figure 1 to Figure 3 As shown, it includes: a vibration sensor 1, a vibration positioning bolt 2, a bracket fastening bolt 3, a gasket 4, a first bracket 5, a temperature sensor 6, a nut 8, a fixing gasket 9, a second metal bracket 10, a bracket positioning screw 11, a temperature sensor positioning screw 13, a vibration positioning gasket 15 and a vibration positioning nut 16.
[0024] The vibration sensor 1 is detachably mounted on the first bracket 5 through two sets of the vibration positioning bolts 2, the vibration positioning gaskets 15 and the vibration positioning nuts 16;
[0025] The first bracket 5 is detachably mounted on the second bracket 10 through two sets of the bracket fastening bolts 3, the washers 4, and the nuts 8;
[0026] The second bracket 10 is installed on the upper part of the bearing end cover 7 of the dust removal motor through two bracket positioning screws 11, a bearing end cover screw 12 provided by the original machine, and a fixing gasket 9;
[0027] The temperature sensor 6 is fixed in the assembly hole opened on the side of the second bracket 10 by the temperature sensor positioning screw 13 .
[0028] On the basis of the above embodiment, it can be further specifically explained that the two bracket positioning screws 11 and the bearing end cover screws 12 of the original machine are arranged in a triangular position; as for the shape of the two brackets, in actual operation, the first bracket 5 preferably adopts an L-shaped structure, and the second bracket 10 preferably adopts an L-shaped structure, the first bracket 5 is connected to the horizontal plate of the L-shaped structure of the second bracket 10, and an open groove is provided on the vertical plate of the L-shaped structure of the second bracket 10 for connecting the bearing end cover screws 12.
[0029] For the selection specifications of the aforementioned components, you can refer to the following: the temperature sensor can adopt PT100 7X35 / 350 platinum resistance; the vibration sensor can adopt Pepperl+Fuchs' ACY04-F99-2I-V15; the vibration positioning bolt 2 has a specification of M4×14-N; the vibration positioning gasket 15 has a specification of φ4; the vibration positioning nut 16 has a specification of M4-N; the bracket fastening bolt 3 has a specification of M5×25-N; the gasket 4 has a specification of φ5; the nut 8 has a specification of M5-N; the bracket positioning screw 11 has a specification of M5×8-N; the temperature sensor positioning screw 13 has a specification of M3×4-N; wherein, at least the second bracket 10 is preferably made of aluminum material.
[0030] Finally, the working principle of the utility model is schematically explained as follows: by fixing the integrated vibration and temperature sensor bracket to the upper part of the bearing end cover of the dust removal motor, fixing it with the original bearing end cover screws, and adding two screws to achieve three-point fixation in the plane, the second bracket is tightly attached to the bearing end cover. In this way, when the dust removal fan bearing heats up, the temperature increase is transmitted to the bearing end cover. When the temperature of the bearing end cover increases, the temperature is transmitted to the aluminum second bracket. At this time, the temperature sensor in the second bracket detects the temperature increase, indicating that the bearing has a temperature rise fault and needs to be inspected and repaired; the vibration sensor is fixed on the first bracket, and the first bracket and the second bracket are connected and fixed on the bearing end cover together. In this way, when there is an internal fault in the bearing, the vibration of the bearing end cover increases and the vibration phenomenon is transmitted to the vibration sensor through the first bracket and the second bracket. At this time, when the detected vibration has a relatively obvious increase, it can cooperate with the alarm device of the equipment (not within the scope of the focus of the utility model) to send out an alarm signal to trigger the shutdown. This is not limited by the utility model.
[0031] In summary, the main design concept of the utility model is that it consists of a vibration sensor, a vibration positioning bolt, a bracket fastening bolt, a gasket, a first bracket, a temperature sensor, a nut, a fixed gasket, a second bracket made of metal material, a bracket positioning screw, a temperature sensor positioning screw, a vibration positioning gasket and a vibration positioning nut, wherein the vibration sensor is detachably mounted on the first bracket, the temperature sensor is fixed at the second bracket, the first bracket and the second bracket are detachably mounted, and the second bracket is mounted on the bearing end cover of the dust removal motor through two bracket positioning screws, a bearing end cover screw that comes with the original machine, and a fixed gasket. The motor temperature is transmitted to the temperature sensor by the fitting installation of the second bracket and the bearing end cover, and the vibration generated by the motor is transmitted to the vibration sensor at the first bracket through the two interconnected brackets, thereby realizing the function of integrated detection of temperature and vibration. The utility model fills the blind spot of bearing detection in the dust removal motor and improves the sensitivity and maintainability of detection.
