The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0039] In order to better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0040] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0041] Reference below Figure 1-Figure 5 , the implementation of the tungsten powder feeding and smoothing mechanism proposed in the embodiment of the utility model is described in detail.

[0042] The tungsten powder unloading and smoothing mechanism according to the embodiment of the utility model is suitable for unloading the tungsten powder in the boat to the next process, and comprises: a rotating disk 11 , a scraping member 21 and a smoothing member 31 .

[0043] Specifically, the scraper 21 is rotatably arranged on the turntable 11; the smoothing member 31 is swingably arranged on the turntable 11; the turntable 11 is rotatably arranged. When the turntable 11 rotates, the turntable 11 drives the scraper 21 in a self-rotating state and the smoothing member 31 in a swinging state to rotate around the rotation center of the turntable 11 to smooth the tungsten powder in the boat and scrape it to the discharge port of the boat.

[0044] That is to say, due to the high density and poor fluidity of tungsten powder, it is difficult to discharge from the boat and is easy to adhere to the inner wall of the boat. The tungsten powder accumulated on the inner wall of the boat can be broken up and spread out by the swinging smoothing member 31 driven by the turntable 11. At the same time, the tungsten powder in the boat can be scraped and sent to the discharge port of the boat by the rotating scraping member 21 driven by the turntable 11 for unloading.

[0045] Thus, the rotating scraper 21 and the swinging smoothing member 31 are driven by the turntable 11 to rotate synchronously, and the tungsten powder in the boat is smoothed and scraped to the discharge port of the boat. The tungsten powder unloading and smoothing mechanism has high unloading efficiency and the tungsten powder is not easy to remain in the boat.

[0046] As for the scraper 21 and the smoothing member 31, the scraper 21 has a scraper 211 and a first connecting shaft 212, the scraper 211 is connected to the first connecting shaft 212, the first connecting shaft 212 is rotatably mounted on the turntable 11, and the smoothing member 31 has a smoothing rod 311 and a second connecting shaft 312, the smoothing rod 311 is connected to the second connecting shaft 312, and the second connecting shaft 312 is swingably mounted on the turntable 11. It can be understood that the scraper 211 and the smoothing rod 311 can be extended by setting the first connecting shaft 212 and the second connecting shaft 312 to better match the boat. Among them, the scraper 21 can be set to a flat shape with a certain length and width, so as to improve the scraping efficiency of tungsten powder, and the smoothing rod 311 can be an L-shaped round rod, and the smoothing rod 311 can be as close to the inner wall of the boat as possible when swinging.

[0047] For the installation of the scraper 211 and the trowel rod 311, the scraper 211 is detachably connected to the first connecting shaft 212; the trowel rod 311 is detachably connected to the second connecting shaft 312. It can be understood that the detachable connection between the scraper 211 and the trowel rod 311 facilitates the installation and maintenance of the scraper 211 and the trowel rod 311. The scraper 211 and the trowel rod 311 can be connected to the first connecting shaft 212 and the second connecting shaft 312 in a one-to-one correspondence through threads.

[0048] For the movement of the scraper 211 and the smoothing rod 311, the first gear 41 is also included. The first gear 41 is rotatably arranged relative to the turntable 11. The first connecting shaft 212 is connected to the second gear 213. The second connecting shaft 312 is connected to the third gear 314 through the connecting rod mechanism 313. The second gear 213 and the third gear 314 are both meshed with the third gear 314. It can be understood that since the boat is mostly cylindrical, when the first gear 41 rotates, it drives the second gear 213 and the third gear 314 to revolve around the rotation center of the first gear 41, and at the same time, the second gear 213 can be rotated, so that the scraper 211 can realize the revolution and rotation synchronously. When the third gear 314 rotates, the connecting rod mechanism 313 can drive the smoothing rod 311 to swing and revolve around the rotation center of the first gear 41, so that the scraper 211 and the smoothing rod 311 can more fully flatten the tungsten powder in the boat and scrape it to the discharge port of the boat.

[0049] For the swing of the smoothing member 31, the connecting rod mechanism 313 has an eccentric shaft 3131, a first connecting arm 3132, a second connecting arm 3133 and a third connecting arm 3134. The third gear 314 is installed on the eccentric shaft 3131. The first connecting arm 3132 is hinged to the output end of the eccentric shaft 3131. One end of the second connecting arm 3133 is hinged to the first connecting arm 3132. The other end of the second connecting arm 3133 is slidably connected to the sliding groove of the third connecting arm 3134. The second connecting shaft 312 is connected to the third connecting arm 3134. It can be understood that when the rotating disk 11 rotates, the third gear 314 is driven to rotate. The third gear 314 drives the eccentric shaft 3131 to push the first connecting arm 3132 to move, so that the second connecting arm 3133 drives the third connecting arm 3134 to move, and then the second connecting shaft 312 drives the smoothing rod 311 to swing repeatedly. Among them, the swing angle of the smoothing rod 311 can be about 150°.

[0050] Furthermore, it also includes a first flange 42 and a second flange 43, the rotating disk 11 is rotatably mounted on the first flange 42, the first gear 41 is arranged below the rotating disk and mounted on the first flange 42, the second flange 43 is connected to the first flange 42, the first flange 42 and the second flange 43 jointly construct a first sealed space, the first connecting shaft 212 and the second connecting shaft 312 are respectively penetrated through two through holes of the second flange 43 so that the scraper 211 and the smoothing rod 311 are outside the first sealed space. It can be understood that the first flange 42 and the second flange 43 jointly construct the first sealed space so that the first gear 41, the second gear 213, the third gear 314, the connecting rod mechanism 313, the moving pair and the rotating disk 11 are all in the sealed space, while the scraper 211 and the smoothing rod 311 are outside the sealed space, thereby preventing tungsten powder or other dust from entering the sealed space and affecting the normal operation of the equipment. Among them, the connection between the first connecting shaft 212 and the scraper 211, and the connection between the second connecting shaft 312 and the smoothing rod 311 can be outside the sealed space, which is convenient for replacing the scraper 211 and the smoothing rod 311. The first connecting shaft 212 and the second connecting shaft 312 are rotatable through bearings and pass through the through holes of the second flange 43; the turntable 11 is installed in the mounting groove of the first flange 42 through bearings; in addition, the second connecting arm 3133 can be installed on the second flange 43 through a moving pair, which is convenient for improving the strength of the connecting rod mechanism 313.

[0051] Furthermore, it also includes a rotation drive assembly 51, which includes a rotation drive member 511, a fourth gear 512 and a fifth gear 513. The fourth gear 512 is mounted on the first flange 42, and the fourth gear 512 is meshed with the fifth gear 513. The rotation drive member 511 is connected to the fifth gear 513 to drive the fifth gear 513 to rotate so that the fourth gear 512 drives the first flange 42 to rotate. It can be understood that the rotation drive member 511 drives the fourth gear 512 to rotate, so that the fifth gear 513 drives the first flange 42 to rotate, thereby driving the scraper 211 to rotate and revolve, and driving the smoothing member 31 to swing and revolve. Among them, the rotation drive member 511 can be a motor, and the fourth gear 512 can be an external gear and is sleeved on the first flange 42.

[0052] Further, the first flange 42 is rotatably arranged in the third flange 44, and the upper end of the third flange 44 is connected to a cover plate 45, which is rotatably connected to the first flange 42. The first flange 42, the third flange 44 and the cover plate 45 jointly construct a second sealed space so that the first gear 41 and the second gear 213 are in the second sealed space. It can be understood that the second sealed space is jointly constructed by the first flange 42, the third flange 44 and the cover plate 45, so that the fourth gear 512 and the fifth gear 513 are rotatably in the second sealed space, thereby preventing tungsten powder or other dust from entering the second sealed space and affecting the normal operation of the equipment. Among them, the first flange 42 can be installed in the installation groove of the third flange 44 through a bearing, and the first flange 42 is connected to the cover plate 45 through a bearing.

[0053] Furthermore, a shield 46 is included, and the shield 46 is connected to the third flange 44 through a fourth flange 47. The shield 46 is suitable for connecting to the boat so that the scraper 211 and the smoothing rod 311 can operate in the boat. It can be understood that the shield 46 is provided to facilitate better docking with the boat, thereby facilitating the operation of the scraper 211 and the smoothing rod 311 in the boat. Among them, the matching part of the shield 46 and the boat can be set to a circular folded edge, which is convenient for quick docking with the boat.

[0054] Furthermore, a detection switch 48 is included, and the detection switch 48 is arranged on the cover plate 45 to detect the rotation state of the first flange 42. It can be understood that by detecting the rotation state of the first flange 42 by the detection switch 48, the host controls the number of revolutions of the turntable 11, and then accurately controls the working time of the scraper 211 and the smoothing rod 311 to ensure that the tungsten powder in the boat is completely emptied.

[0055] In addition, sealing rings are provided at the connection between the first connecting shaft 212 and the second flange 43, the connection between the second connecting shaft 312 and the second flange 43, and the connection between the third flange 44 and the cover plate 45 to prevent tungsten powder or other dust from entering the first sealed space or the second sealed space.
