Specific Embodiments

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

[0024] Please refer to Figures 1 to 3 , the present invention provides a technical solution: a powder feeding mechanism for plasma spraying, including a storage box 1, the left side of the storage box 1 is hinged with a box cover 2 through a hinge, the inside of the storage box 1 is provided with a powder feeding mechanism 300 for realizing powder feeding, and an observation window 5 is fixed on the front of the storage box 1.

[0025] Through the combined use of the storage box 1, the powder feeding mechanism 300, and the observation window 5, during actual use, when it is necessary to add and supplement the spraying powder in the powder bucket, the spraying powder can be quickly and effectively added without removing the powder bucket, and the plasma spraying equipment can work normally during the addition process, thereby improving its working efficiency. At the same time, the spraying powder in the powder bucket can also be monitored. When the spraying powder is less, an alarm can be issued in a timely and effective manner, so as to notify the staff, effectively avoiding mechanical failures caused by the spraying powder being used up without the staff's knowledge, and improving the practicality of the plasma spraying powder feeding mechanism.

[0026] In this embodiment, the powder feeding mechanism 300 is a structure for realizing powder feeding.

[0027] As Figure 1 、 Figure 2 and Figure 3 shown, the powder feeding mechanism 300 includes a controller 301 fixed to the left side of the storage box 1, an alarm 302 fixed to the left side of the storage box 1, first triangular prisms 303 fixed to both the left and right inner side walls of the storage box 1, a fixed frame 304 fixed to the bottom of the first triangular prism 303, a laser emitter 305 fixed inside the left fixed frame 304, a laser receiver 306 fixed inside the right fixed frame 304, second triangular prisms 307 fixed to both the left and right inner side walls of the storage box 1, two adjusting plates 308 slidably connected to the inner bottom wall of the storage box 1, and an adjusting assembly 309 for adjusting the adjusting plates 308 provided inside the storage box 1.

[0028] It should be noted that the adjusting assembly 309 includes screws 3091 threadedly connected to the inside of the adjusting plates 308, adjusting blocks 3092 fixed to the opposite ends of the two screws 3091, stabilizing blocks 3093 fixed to the bottom of the adjusting plates 308, and two stabilizing grooves 3094 opened on the inner bottom of the storage box 1.

[0029] Among them, the stabilizing block 3093 is slidably connected inside the stabilizing groove 3094 to ensure that the adjusting plate 308 moves left and right more stably through the stabilizing block 3093 and the stabilizing groove 3094. The width of the stabilizing block 3093 is equal to the width of the stabilizing groove 3094, so that the stabilizing block 3093 slides more stably in the stabilizing groove 3094. The adjustable distance of the stabilizing block 3093 inside the stabilizing groove 3094 is less than the adjustable distance of the screw 3091 in the adjusting plate 308, effectively avoiding the situation where the screw 3091 and the adjusting plate 308 fall off during the adjustment process.

[0030] In addition, a discharge pipe 4 is fixed to the bottom of the storage box 1 to ensure that the sprayed powder can be discharged. The diameter of the adjusting block 3092 is larger than that of the screw 3091, which facilitates the rotation of the screw 3091 through the adjusting block 3092. The width of the adjusting plate 308 is larger than the diameter of the discharge pipe 4, ensuring that the powder discharge amount of the discharge pipe 4 can be effectively controlled through the adjusting plate 308.

[0031] In addition, the top of the adjusting plate 308 is slidably connected to the bottom of the second triangular prism 307, making the adjustment of the adjusting plate 308 more stable. The opposite sides of the two fixing frames 304 are respectively fixed to the left and right inner side walls of the storage box 1, ensuring that the fixing frames 304 can be fixed more stably. The opposite ends of the two screws 3091 sequentially penetrate through the storage box 1 and the adjusting plate 308 and are threadedly connected to the adjusting plate 308. The outer side of the screw 3091 is rotationally connected to the storage box 1 through a bearing, ensuring that the screw 3091 can be effectively threadedly connected to the adjusting plate 308 to drive the adjusting plate 308 to adjust and ensuring that the screw 3091 can rotate effectively in place.

[0032] At the same time, the output end of the controller 301 is electrically connected to the input end of the alarm 302, and the input end of the controller 301 is electrically connected to the output end of the laser receiver 306, ensuring that when the laser receiver 306 can receive the laser signal emitted by the laser transmitter 305, it transmits its information to the controller 301, and then controls the alarm 302 to emit an alarm.

[0033] The working principle of the above embodiment is as follows:

[0034] During use, when there is a large amount of sprayed powder in the storage box 1, the laser emitted by the laser transmitter 305 is blocked by the sprayed powder, so that the laser receiver 306 cannot receive the laser signal. When there is less sprayed powder in the storage box 1, the laser receiver 306 can receive the laser signal emitted by the laser transmitter 305, transmits its information to the controller 301, and then controls the alarm 302 to emit an alarm, thus achieving the effect of reminding the staff. Just open the box cover 2 to effectively add the sprayed powder into the storage box 1. Under the action of the first triangular prism 303 and the fixing frame 304, the laser emitted by the laser transmitter 305 and the laser receiver 306 can be effectively protected. Then, the sprayed powder can be fed through the second triangular prism 307 and the discharge pipe 4. During actual use, when the required powder feeding amount is different, rotate the two adjusting blocks 3092 to drive the screw 3091 to rotate in place. Under the action of the internal threaded rotation thrust and the limiting effect of the stabilizing block 3093, the adjusting plate 308 moves left and right at the bottom of the storage box 1, so that the adjusting plate 308 can block the discharge pipe 4 to a certain extent, and thus the powder output amount can be effectively adjusted.

[0035] Compared with the prior art, in the powder feeding mechanism of this plasma spraying, through the combined use of the storage box 1, the controller 301, the adjusting plate 308, the adjusting block 3092 and the observation window 5 in the powder feeding mechanism 300, during actual use, when it is necessary to add and supplement the spraying powder in the powder bucket, the spraying powder can be quickly and effectively added without removing the powder bucket, and the plasma spraying equipment can work normally during the addition process, thereby improving its working efficiency. At the same time, it can also monitor the spraying powder in the powder bucket. When the spraying powder is less, it can issue an alarm in a timely and effective manner, so as to notify the staff, thus effectively avoiding mechanical failures caused by the staff's ignorance when the spraying powder is used up, improving the practicability of the plasma spraying powder feeding mechanism, and solving the problem of the low practicability of the existing plasma spraying powder feeding mechanism.

[0036] All the electrical components mentioned in the text are electrically connected to the controller and the power supply. The control mode of the present invention is controlled by the controller. The control circuit of the controller can be realized by simple programming by those skilled in the art. The provision of the external power supply also belongs to the common knowledge in the art. And the present invention is mainly used to protect mechanical devices, so the control mode and circuit connection of the present invention will not be explained in detail.
