DETAILED DESCRIPTION

[0050] Example 1: Please refer to Figure 1-Figure 3 and Figure 5-Figure 7 As shown, during the use of the existing stirring mixer for tungsten powder processing, the materials need to be added at one time, so that multiple materials are stacked separately, and automatic intermittent feeding cannot be achieved, thereby reducing the mixing effect of the materials. In order to solve this technical problem, this embodiment discloses the following technical content;

[0051] A multi-directional stirring mixer for tungsten powder processing comprises a base 1 stably placed in a workshop, a support seat 2 is rotatably installed above the base 1, and a mixing barrel 3 is rotatably arranged inside the support seat 2;

[0052] It also includes: a fixing frame 4, fixedly mounted on the lower outer side of the support seat 2, a driving motor 5 is fixedly mounted on the fixing frame 4, a driving gear 8 is fixedly mounted on the output end of the driving motor 5, a driving shaft 6 is rotatably mounted on the fixing frame 4, and the output end of the driving motor 5 and the left end of the driving shaft 6 are connected by a transmission belt 7;

[0053] The gear ring 9 is fixedly mounted on the outer side of the left end of the mixing barrel 3; the support frame 10 is fixedly mounted on the outer side of the upper part of the support seat 2, the outer side of the support frame 10 is fixedly mounted with a hopper 11, and the inner side of the hopper 11 is provided with a dredging rod 12, and a dredging assembly 13 is installed between the hopper 11 and the dredging rod 12;

[0054] The driving gear 8 is meshedly connected with the gear ring 9, and the mixing barrel 3 is driven by the gear ring 9 to rotate, and the mixing barrel 3 and the driving shaft 6 are coaxially arranged, and the mixing barrel 3 and the driving shaft 6 rotate in opposite directions.

[0055] A feeding hole 301 is provided on the outer side of the right end of the mixing barrel 3, and the lower end of the hopper 11 passes through the support seat 2, and the feeding hole 301 and the lower end of the hopper 11 are intermittently connected during the rotation of the mixing barrel 3.

[0056] The hopper 11 and the dredging rod 12 are coaxially arranged, and the lower end of the dredging rod 12 is arranged in a conical structure, and the dredging rod 12 forms an elastic lifting structure through the dredging assembly 13 and the hopper 11. At the same time, when the feeding hole 301 and the lower end of the hopper 11 are moving away from and offset, the lower end inclined surface of the dredging rod 12 will be resisted by the inner wall of the feeding hole 301.

[0057] The dredging assembly 13 includes a movable rod 1301 elastically rotatably mounted on the inner wall of the hopper 11 and a movable cylinder 1302 elastically rotatably mounted on the upper part of the dredging rod 12, and the movable rod 1301 and the movable cylinder 1302 are telescopically connected.

[0058] Two paddles 1303 are symmetrically and elastically mounted on the outer wall of the movable cylinder 1302, and a limit plate is arranged on the outer side of the movable cylinder 1302 to limit the upward rotation angle of the paddle 1303. When the movable cylinder 1302 moves upward and resets, the paddle 1303 will be elastically rotated downward under the obstruction of the material.

[0059] By adopting the above technical solution, the raw materials are put into the hopper 11, and the driving motor 5 is started, so that the driving gear 8 installed on the outer side of the output shaft of the driving motor 5 rotates, and the driving gear 8 will drive the gear ring 9 and the mixing barrel 3 to rotate through the meshing action. At this time, the feeding hole 301 opened on the mixing barrel 3 will intermittently pass through the lower end of the hopper 11 and communicate with the hopper 11. At this time, the hopper 11 will feed part of the material inside it into the mixing barrel 3 through the feeding hole 301, and when the feeding hole 301 and the lower end of the hopper 11 are staggered, the lower end of the hopper 11 can be closed to avoid mixing difficulties caused by the material being put in at one time. When the feeding hole 301 and the lower end of the hopper 11 are gradually staggered away, the vertebral body at the lower end of the dredging rod 12 will be resisted by the inner wall of the feeding hole 301, thereby making the dredging The rod 12 elastically rises, and the dredging rod 12 drives the movable cylinder 1302 to move upward synchronously. At this time, the movable rod 1301 and the movable cylinder 1302 rotate synchronously and adjust their extension and contraction. At the same time, the paddle 1303 rotates downward under the resistance of the raw material. When the feeding hole 301 and the lower end of the hopper 11 are connected again, the movable rod 1301 and the movable cylinder 1302 rotate elastically to reset and contract, thereby driving the dredging rod 12 to move downward, and the paddle 1303 on the outer side of the movable cylinder 1302 rotates upward and moves downward. Since the upward rotation angle of the paddle 1303 is limited, the paddle 1303 can cooperate with the dredging rod 12 to push the powder downward, thereby promoting the feeding of the powder, avoiding blockage at the discharge port of the hopper 11, and realizing automatic dredging.

[0060] Embodiment 2: The technical content disclosed in this embodiment is a further improvement on the above embodiment 1. The stirring mechanism of the existing stirring mixer for tungsten powder processing is fixed, so that stirring can only be performed in a fixed direction at a fixed position, thereby limiting the stirring range and resulting in poor mixing effect. In order to further solve this technical problem, this embodiment discloses the following technical content, such as Figure 1-Figure 4 and Figure 8-Figure 10 As shown;

[0061] The stirring assembly is arranged on the mixing barrel 3 and the driving shaft 6 to realize multi-directional stirring of the tungsten powder; the counterweight block 19 is fixedly installed on the outer side of the mixing barrel 3; the buffer assembly 20 is supported and installed between the base 1 and the fixed frame 4 to realize buffer support for the mixing barrel 3.

[0062] The stirring assembly includes a first stirring rod 14 screw-fixedly mounted on the inner wall of the mixing barrel 3 and a sliding sleeve 16 slidably mounted on the outer side of the driving shaft 6 , and a second stirring rod 17 is evenly fixedly mounted on the outer side of the sliding sleeve 16 .

[0063] A second magnetic block 1701 is fixedly installed on the outer end of the second stirring rod 17, and a first magnetic block 1401 is fixedly installed on the outer side of one end of the first stirring rod 14 close to the inner wall of the mixing barrel 3, and the magnetic poles of the opposite surfaces of the first magnetic block 1401 and the second magnetic block 1701 are opposite, and fixing rings 15 are evenly arranged on the outer side of the driving shaft 6, and a return spring 18 is connected between the fixing ring 15 and the sliding sleeve 16.

[0064] The counterweight block 19 rotates synchronously with the mixing barrel 3 at a high speed, and the mixing barrel 3 drives the support seat 2 to reciprocate on the base 1 under the centrifugal force of the counterweight block 19 .

[0065] The buffer assembly 20 includes a support tube 21 rotatably mounted above the base 1 and a telescopic rod 22 rotatably mounted below the fixing frame 4.

[0066] The support tube 21 and the telescopic rod 22 are elastically connected, and a buffer spring 23 is connected between the support tube 21 and the telescopic rod 22.

[0067] By adopting the above technical solution, as the driving motor 5 is started, its output end will drive the driving shaft 6 to rotate synchronously through the transmission belt 7, and at the same time, the driving gear 8 installed at the output end of the driving motor 5 will be meshed and connected with the gear ring 9 to drive the gear ring 9 and the mixing barrel 3 to rotate synchronously. At this time, the mixing barrel 3 and the driving shaft 6 rotate in opposite directions. At the same time, the first stirring rod 14 on the mixing barrel 3 and the second stirring rod 17 on the driving shaft 6 can stir and mix the tungsten powder material in both directions. As the first stirring rod 14 and the second stirring rod 17 are stirred, the two will approach each other intermittently. At this time, the first magnetic block 1401 and the second magnetic block 1701 on the first stirring rod 14 and the second stirring rod 17 will generate magnetic force, so that The sleeve 16 slides elastically along the drive shaft 6 under the action of magnetic force, thereby adjusting the stirring position of the second stirring rod 17 outside the sleeve 16, thereby effectively expanding the stirring range and effect of the stirring mechanism of the equipment. At the same time, during the rotation of the mixing barrel 3, the counterweight block 19 on its outside will drive the mixing barrel 3 and the support seat 2 to reciprocate and rotate around the base 1 under the action of centrifugal force, so that the mixing barrel 3 can shake the material inside it, thereby further improving the turning and mixing effect of the material. During the rotation of the support seat 2, the support tube 21 and the telescopic rod 22 will elastically contract under the elastic force of the buffer spring 23, thereby realizing buffer support for the support seat 2 and ensuring the stability of the mixing barrel 3 when shaking.
