DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example: An anti-clogging automatic sandblasting device for powder metallurgy products, such as Figure 1 、 Figure 2 and Figure 4As shown, it includes an outer frame 1, a door panel 2 and a cover plate 3. The outer frame 1 is a sandblasting container of the present device. The outer frame 1 is a cylindrical frame body. The door panel 2 is hinged to one side of the lower part of the outer frame 1, and the cover plate 3 is fixed to the top of the outer frame 1; it also includes: a sliding rod 4, which is symmetrically slidably installed on the inner wall of the outer frame 1, and a sliding groove is opened on the side wall of the outer frame 1 at the position of the sliding rod 4; a slider 5, which is fixed to the upper outer side of the sliding rod 4, and the slider 5 is located in the sliding groove of the outer frame 1; a fixed block 6, which is fixed in the side wall sliding groove of the outer frame 1; a spring I 7, which is arranged between the slider 5 and the fixed block 6; a fixed rod 8, which is symmetrically fixed to the sliding rod 4; two nozzles 9, which are installed on the sliding rod 4 through the fixed rod 8; a sand pump 10, which is installed on the top surface of the cover plate 3; a connecting pipe 11, which is connected to the outlet of the sand pump 10 and the nozzles 9 on both sides; a mounting plate 12, which is fixedly arranged on the inner wall of the lower part of the outer frame 1 On the wall, a compartment is provided between the mounting plate 12 and the inner bottom of the outer frame 1; the rotating plate 13 is rotatably mounted at the center of the top surface of the mounting plate 12, and the center of the top surface of the rotating plate 13 is used to place the metallurgical products to be processed; the motor 131 is mounted on the bottom of the inner wall of the outer frame 1, and the output shaft of the motor 131 passes through the mounting plate 12 and the rotation center of the rotating plate 13 and is connected; the push plate 15 is symmetrically fixed to the side wall of the rotating plate 13, and the push plate 15 is used to push and squeeze the sliding rod 4; the external sand powder is drawn from the connecting pipe 11 into the multiple nozzles 9 for pressurized spraying through the sand pump 10, and the metallurgical products placed on the rotating plate 13 are driven by the motor 131 to be uniformly sandblasted. The push plates 15 on both sides of the rotating plate 13 intermittently squeeze the sliding rod 4 through the inclined surface thereon, so that the sliding rod 4 drives the nozzle 9 thereon to vibrate, thereby reducing the risk of clogging of the nozzle 9.

[0024] like Figure 2 and Figure 3 As shown, the push plate 15 and the mounting plate 12 are in sliding contact, and a slope is provided on the top surface of the end of the push plate 15 that is away from each other. The slopes of the two push plates 15 are opposite, and the lower end of the sliding rod 4 is an inclined end surface that is adapted to the slope of the push plate 15. After the push plate 15 is rotated to slide and press the sliding rod 4, the sliding rod 4 drives the nozzle 9 thereon to compress the spring upward and bounce up. After the push plate 15 slides away from the sliding rod 4, the sliding rod 4 is reset and moved downward under the action of the spring I7, thereby reciprocating so that the nozzle 9 on the sliding rod 4 can achieve fine vibration sandblasting, reducing the clogging of the nozzle 9 without affecting the sandblasting.

[0025] like Figure 2As shown, a circular bucket-shaped sand leakage port 121 is provided on one side of the mounting plate 12. The sand leakage port 121 is used to guide and discharge the sand powder scraped by the push plate 15 on the mounting plate 12, so as to avoid waste of sand powder accumulated on the mounting plate 12 by the nozzle 9; the nozzles 9 on both sides are inclined toward the metallurgical products placed on the central top surface of the rotating plate 13, and the actual sandblasting angle of the nozzle 9 can be adjusted by tools on the fixed rod 8, thereby improving the ability of the nozzle 9 to adapt to the spraying requirements of metallurgical products of different sizes and improving the scope of application of the device.

[0026] like Figure 2 and Figure 5 As shown, a magnetic block 16 is provided on the rotating plate 13, and multiple magnetic blocks 16 are installed at the center of the rotating plate 13. The metallurgical products can be stably adsorbed at the center position of the rotating plate 13 through the magnetic block 16, thereby improving the stability of the metallurgical products placed on the rotating plate 13; the inner bottom of the outer frame 1 is equipped with a collecting tank 17, and the top of the collecting tank 17 is provided with an opening aligned with the sand leakage port 121. The collecting tank 17 is used to collect sand powder leaked from the sand leakage port 121, thereby improving the recycling of sand powder; a vibrator 18 is also installed on the sliding rod 4, and the vibrator 18 is used to vibrate the sliding rod 4, so that the nozzle 9 on the sliding rod 4 can continuously vibrate during sand blasting, thereby preventing sand powder from accumulating and clogging at the outlet of the nozzle 9, further improving the anti-clogging effect of the nozzle 9.

[0027] like Figure 5 As shown, a fixing plate 19 is fixedly connected in the compartment at the bottom of the mounting plate 12 and the outer frame 1, and a push rod 20 is slidably installed on the fixing plate 19. The push rod 20 is used to push out the collection tank 17. A spring II 21 is provided between the fixing plate 19 and the push rod 20. A limit block 22 for limiting the collection tank 17 is provided on the door panel 2. By closing the door panel 2, the limit block 22 is pressed on the collection tank 17, so that the collection tank 17 squeezes the push rod 20 and then aligns with the sand leakage port 121. Under the action of the spring II 21, the push rod 20 cooperates with the limit block 22 to stably clamp both sides of the collection tank 17.

[0028] First, place the metallurgical product to be processed at the center of the rotating plate 13 and stably adsorb it through the magnetic block 16. Close the door panel 2 to ensure a closed working environment. At this time, the limit block 22 on the door panel 2 will press the collection tank 17. The collection tank 17 pushes the push rod 20 and compresses the spring II 21. When the collection tank 17 is aligned with the sand leakage port 121, the collection tank 17 is clamped and fixed by the push rod 20 and the limit block 22 under the action of the spring II 21. Then, start the sand pump 10 to extract sand powder from the external sand powder source. The liquid is then delivered to the nozzles 9 on both sides through the connecting pipe 11. At the same time, the motor 131 starts working, and its output shaft drives the rotating plate 13 and the metallurgical products thereon to rotate at a constant speed. As the rotating plate 13 rotates, the push plate 15 located on the side wall of the rotating plate 13 also moves accordingly. When the inclined surface of the push plate 15 contacts the inclined end surface of the sliding rod 4, the push plate 15 exerts an upward force on the sliding rod 4, causing the sliding rod 4 and the nozzle 9 thereon to move upward and compress the spring Ⅰ 7. When the push plate 15 slides over the sliding rod 4, the push plate 15 will move upward. , the sliding rod 4 is reset under the elastic force of the spring I 7. During this process, the nozzle 9 on the sliding rod 4 will produce slight vibrations. As the rotating plate 13 continues to rotate, the metallurgical product on it is evenly covered by the sandblasting of the nozzle 9. Since the nozzle 9 on the sliding rod 4 is continuously affected by the vibration, even if a small amount of sand powder accumulates near the outlet of the nozzle 9, it is difficult to form a stable blockage. In addition, by activating the vibrator 18, the vibration effect of the nozzle 9 can be further enhanced, which helps to keep the nozzle 9 unobstructed. During the sandblasting process, the excess sand powder not attached to the metallurgical product will be scraped by the push plate 15 to the sand leakage port 121 on one side of the mounting plate 12, and finally fall into the collection tank 17 below. This not only avoids the waste of sand powder, but also facilitates subsequent reuse. After the sandblasting operation is completed, the door panel 2 is rotated to open, and the collection tank 17 is pushed out by the push rod 20 under the action of the spring II 21, which is convenient for the subsequent recycling of the sand powder in the collection tank 17. Finally, the metallurgical product after sandblasting is removed from the rotating plate 13.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
