[0022] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0023] Reference Figure 1-3 As shown, a talcum powder box stop alarm device comprises a talcum powder box 1, a spiral stirring shaft 2 transversely arranged in the talcum powder box 1, and four groups of legs 3 respectively fixed on the four corners of the bottom surface of the talcum powder box 1, a connecting plate 4 is fixed between two legs 3 on the same side, one end of the spiral stirring shaft 2 is rotatably connected to the inner wall of the talcum powder box 1 through a bearing, and the other end of the spiral stirring shaft 2 rotates to pass through the talcum powder box 1, and a driving mechanism for providing a rotating force for the spiral stirring shaft 2 is arranged on one of the connecting plates 4;

[0024] The driving mechanism includes a motor 5 installed on one side of a connecting plate 4, the output shaft of the motor 5 rotates through the connecting plate 4 and is tightly sleeved with a first transmission wheel 6, one end of the spiral stirring shaft 2 located outside the talcum powder box 1 is tightly sleeved with a second transmission wheel 19, and a transmission belt 7 is connected between the first transmission wheel 6 and the second transmission wheel 19;

[0025] When in use, the motor 5 is turned on, and the output shaft of the motor 5 drives the first transmission wheel 6 to rotate continuously, so that the second transmission wheel 19 and the spiral stirring shaft 2 as a whole can rotate synchronously under the transmission force of the transmission belt 7, thereby allowing the spiral stirring shaft 2 to continuously stir the talcum powder in the talcum powder box 1.

[0026] Since, in the prior art, the end of the spiral stirring shaft 2 is rotatably connected to the inner wall of the talcum powder box 1 through a bearing, the bearing is immersed in talcum powder for a long time, and a certain amount of small particles of talcum powder can easily enter the gap between the bearing and the spiral stirring shaft 2, which can seriously cause the spiral stirring shaft 2 to get stuck and stop rotating. Once manual maintenance is not timely, it is very easy to cause thousands of meters or more of sheathed cables to be scrapped.

[0027] For this purpose, refer to Figure 1-3 As shown, it is worth noting that an emergency alarm mechanism is provided on the outside of the talcum powder box 1;

[0028] The emergency alarm mechanism includes a telescopic bracket and a controller 14 installed on the outer wall of the talcum powder box 1, an alarm 15 is installed on the top of the controller 14, a Hall sensor 9 is provided on the telescopic bracket, the Hall sensor 9 and the alarm 15 are both electrically connected to the controller 14, and a strong magnetic steel 13 corresponding to the detection end of the Hall sensor 9 is fixed to the shaft of the spiral stirring shaft 2 located outside the talcum powder box 1;

[0029] According to the existing GYJ-016163-C motor stall detector, the Hall sensor 9, strong magnetic steel 13, controller 14 and alarm 15 in this scheme are all components of the existing motor stall detector. As technical features that are already well known to the public, this scheme does not give too much introduction to the specific circuit connection, internal structure and usage principle between the components. This invention only roughly explains the usage effect. When the spiral stirring shaft 2 is stuck and stalled, the Hall sensor 9 detects the stall signal and turns on the alarm 15 to send out an alarm, so as to promptly remind the staff to inspect and troubleshoot.

[0030] In the above-mentioned embodiment, the emergency alarm mechanism composed of the Hall sensor 9, the strong magnetic steel 13, the controller 14 and the alarm 15 can use the Hall sensor 9 to promptly issue an alarm when the spiral stirring shaft 2 is stuck and stops rotating. However, from the perspective of actual installation, the prior art generally pre-installs the Hall sensor 9 on a simple bracket, and then uses bolts to fix the simple bracket to the outer wall of the talcum powder box 1, so as to achieve the installation effect of the Hall sensor 9. Once the installation is wrong, the distance between the Hall sensor 9 and the strong magnetic steel 13 is too large, which exceeds the reasonable detection range of the Hall sensor 9. It is necessary to manually remove the bolts first, manually adjust the position of the simple bracket, and finally tighten the bolts to complete the position adjustment of the Hall sensor 9. The actual operation is generally cumbersome and the work efficiency is poor.

[0031] In view of this, refer to Figure 3 As shown, it is worth noting that the telescopic bracket includes a mounting plate 10 with an open bottom and mounted on the outer wall of the talcum powder box 1 by bolts, a movable plate 8 is slidably arranged below the mounting plate 10, a Hall sensor 9 is mounted on the movable plate 8, and an adjustment seat 11 vertically fixed to the movable plate 8 is slidably arranged on the inner side of the mounting plate 10;

[0032] A thread groove is provided in the inner wall of the adjustment seat 11, and an adjustment screw 12 is threadedly connected in the thread groove. An adjustment column 20 is provided above the mounting plate 10, and the adjustment column 20 passes through the mounting plate 10 and is fixed to the adjustment screw 12;

[0033] Through the setting of the telescopic bracket, if the distance between the Hall sensor 9 and the strong magnetic steel 13 is too large due to installation errors, it is only necessary to simply turn the knob to adjust the column 20 so that the adjusting screw 12 rotates in the thread groove, and the adjusting seat 11 can slide on the inside of the mounting plate 10 under the thread structure, and synchronously lift the movable plate 8. In this way, the position of the Hall sensor 9 can be adjusted in a short time without manually disassembling the mounting plate 10, thereby enhancing practicality.

[0034] Further, refer to Figure 3 As shown, it is worth noting that the spiral stirring shaft 2 is located outside the talcum powder box 1 and is also covered with a combination seat 16 that is attached to the outer wall of the talcum powder box 1. The detection end of the Hall sensor 9 and the strong magnetic steel 13 are both located on the inner side of the combination seat 16;

[0035] A mounting block 18 is fixed to the top of the assembly seat 16, and a notch matching the mounting block 18 is provided on the side of the movable plate 8 away from the talcum powder box 1, and the mounting block 18 can be detached from the notch by bolts;

[0036] A side of the assembly seat 16 facing the talcum powder box 1 is provided with an escape groove 17 adapted to the transmission belt 7;

[0037] By setting the combination seat 16, after the Hall sensor 9 is fixedly installed by using the telescopic bracket, the combination seat 16 is immediately covered on the rod body of the spiral stirring shaft 2 located outside the talcum powder box 1, and the top and side of the combination seat 16 are respectively in contact with the bottom surface of the movable plate 8 and the outer wall of the talcum powder box 1, so that the combination seat 16, the talcum powder box 1 and the movable plate 8 form a relatively sealed box body, and the detection end of the combination seat 16 and the strong magnetic steel 13 are sealed and protected, so as to prevent the detection end of the combination seat 16 from being exposed to the external environment for a long time and being attached by a large amount of dust, which affects the use effect;

[0038] During the process of covering the combined seat 16 on the rod body of the spiral stirring shaft 2, it is necessary to pay attention to inserting the belt body of the transmission belt 7 into the inner side of the avoidance groove 17, and then using the avoidance groove 17 to provide a movable space for the transmission belt 7, and at the same time, it is also necessary to pay attention to inserting the mounting block 18 into the notch, so as to use bolts to lock the mounting block 18 in the notch, thereby ensuring a firm connection between the movable plate 8 and the combined seat 16.

[0039] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the specification only describe the principles of the utility model. The utility model may be subject to various changes and improvements without departing from the spirit and scope of the utility model. These changes and improvements fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
