Description

Technical Field

[0001] The invention relates to the field of tungsten powder auxiliary mixing devices, in particular to a tungsten powder auxiliary mixing device for tungsten wire processing. Background Art

[0002] Tungsten wire is a filament made of pure tungsten material. It has many special physical and chemical properties, which makes it widely used in many applications. It has the characteristics of high melting point, high density, good conductivity, good corrosion resistance and high mechanical strength. Tungsten powder is one of the starting materials for making tungsten wire, and it needs to be fully mixed with other materials.

[0003] The Chinese invention patent with publication number CN116078229A discloses a tungsten powder auxiliary mixing device for tungsten wire processing, including a mounting platform, an annular mounting frame, a CNC motor, a crossbar, a bearing, a curved support rod and an annular guide rail, etc.; the bottom of the mounting platform is fixedly connected to the annular mounting frame, the CNC motor is fixedly connected to the annular mounting frame, the output shaft of the CNC motor is keyed to the crossbar, one side of the crossbar is fixedly connected to the outer ring of the bearing, the inner ring of the bearing is keyed to the outer wall of the stirring tank, and the lower part of the mounting platform is evenly distributed and fixedly connected to a number of curved support rods, and the lower part of the curved support rods is jointly fixedly connected to the annular guide rail. By rotating the stirring tank, the high-density material inside the tank body and other low-density materials are turned over and mixed, and the stirring frame rotates and stirs more quickly inside, which can make the hydrochloric acid solution fully exert the effect of chemical reaction and reduce the difficulty of mixing when preparing doped tungsten wire. Although this patent allows the mixing barrel to rotate around the annular guide rail while rotating on its own, which can make the mixing more uniform, the upper and lower positions of the mixing barrel remain unchanged, so that during the mixing process, there will be a certain difference in the distribution of heavier and lighter materials in the mixing barrel at the upper and lower ends of the barrel, making it difficult to mix the upper and lower parts of the mixing barrel more uniformly.

[0004] The Chinese invention patent with publication number CN118751122A discloses a tungsten powder auxiliary mixing device for tungsten wire processing. The patent can solve the above problems. It includes a Mobius ring track, a support seat, a mixing barrel and a fixed rail. The Mobius ring track is arranged on the support seat. The end rails are symmetrically arranged at the edges of both sides of the Mobius ring track. The two ends of the mixing barrel are slidably arranged between the two end rails on one side of the Mobius ring track. The mixing barrel is driven to rotate by a driving mechanism. The driving mechanism includes a main gear, a first motor and a rotating shaft. The two ends of the mixing barrel are respectively assembled and connected with the main gear through the rotating shaft. The fixed rail is arranged on the side of the end rail away from the mixing barrel. The mixing barrel of the invention can move while rotating on the Mobius ring track. The mixing barrel is constantly turned upside down along the path of the Mobius ring track, which can achieve up and down mixing of the materials inside the mixing barrel. With the rotation of the mixing barrel, the mixing effect of the materials in the mixing barrel is better, and a better mixing effect can also be achieved in a shorter time.

[0005] However, the above patent still has the following shortcomings during actual use: the patent can fully mix the tungsten powder in the mixing cylinder with other materials through the Möbius ring track, but a plurality of mixing cylinders are arranged on the Möbius ring track of the patent. If the mixing cylinder is set to a large-volume mixing cylinder, since the Möbius ring track is installed with a plurality of mixing cylinders, the overall volume of the Möbius ring track is also very large, which invisibly occupies too much production floor space and affects the placement layout of other equipment. If the mixing cylinder is set to a small-volume mixing cylinder, the overall volume of the Möbius ring track will be reduced accordingly, but the mixing cylinder capacity will also be reduced, that is, the amount of tungsten powder assisted mixing by one mixing cylinder is also reduced. Although there are multiple mixing cylinders, the amount of tungsten powder assisted mixing by all mixing cylinders is still not considerable, thereby invisibly reducing the processing efficiency of tungsten powder. Summary of the invention

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figure 1-8 The present invention describes the above technical solution in detail through the following embodiments:

[0033] A tungsten powder auxiliary mixing device for tungsten wire processing, comprising a mixing drum 1, a bottom plate 2 and a bottom frame 3, wherein a diagonally arranged feed pipe 11 and a discharge hopper 12 are arranged on the outer wall of the mixing drum 1, a sealing cover 111 is arranged on the feed pipe 11, and a solenoid valve 121 is installed on the discharge hopper 12, connecting flanges 13 are arranged at both ends of the mixing drum 1, a stirring mechanism 4 is arranged in the mixing drum 1, two symmetrically arranged mounting seats 21 are arranged on the top of the bottom plate 2, a first rotating shaft 22 is arranged on the two mounting seats 21 for horizontal rotation, two symmetrically arranged rotating disks 23 are installed on the first rotating shaft 22, and an inclined connecting seat 2 is arranged on the inner side wall of the rotating disk 23 31, a first motor 211 is provided on the outer side wall of one mounting seat 21, the output end of the first motor 211 is fixedly connected to one end of the first rotating shaft 22, a transmission member cooperating with the stirring mechanism 4 is provided on the inner side wall of the mounting seat 21, a driving mechanism 5 for driving the bottom plate 2 to reciprocate left and right is provided in the bottom frame 3, a knocking mechanism 6 for assisting the knocking of the mixing drum 1 is provided on the top of the bottom frame 3, the driving mechanism 5 is connected to the knocking mechanism 6 in transmission, the mixing drum 1 is arranged obliquely, and the connecting flanges 13 at both ends of the mixing drum 1 are respectively fixedly connected to the connecting seats 231 on the two turntables 23, and the bottom plate 2 is arranged on the driving mechanism 5.

[0034] The present invention adopts an inclined mixing drum 1, and the first motor 211, the first rotating shaft 22, and the turntable 23 cooperate to drive the mixing drum 1 to rotate around the axis of the first rotating shaft 22, so that the high and low end positions of the mixing drum 1 can be continuously reversed and replaced, and the driving force of the first motor 211 can be transmitted to the stirring mechanism 4 through the cooperation of the stirring mechanism 4 and the transmission member. The stirring mechanism 4 can stir and mix the tungsten powder and other materials in the mixing drum 1, and the bottom plate 2 and the mixing drum 1 can be driven to move back and forth left and right through the driving mechanism 5, so that the tungsten powder and other materials can be subjected to three-axial mixing and stirring driving forces, ensuring that the tungsten powder can be fully mixed with other materials, reducing the floor space, and improving applicability. The mixing drum 1 can be auxiliaryly knocked by the knocking mechanism 6 to avoid the mixed tungsten powder from being retained in the mixing drum 1.

[0035] The inner wall of the mixing drum 1 is provided with a plurality of spiral plates 14 arranged at equal angles along the circumference thereof, and the spiral plates 14 serve to simply separate the materials in contact with the inner wall of the mixing drum 1 to prevent the materials from being piled up too tightly and affecting the mixing efficiency.

[0036] There is an avoidance interval 15 between the tail end of the spiral plate 14 and the inner wall of the tail end of the mixing barrel 1, and the feed port of the discharge hopper 12 is located in the avoidance interval 15. If the spiral plate 14 is connected to the inner wall of the tail end of the mixing barrel 1, the material is easy to be retained at the connection between the tail end of the spiral plate 14 and the inner wall of the tail end of the mixing barrel 1. Therefore, the avoidance interval 15 is set to avoid the situation where the material is retained on the spiral plate 14.

[0037] When using the device, let the feed pipe 11 be at the high end of the mixing barrel 1, then remove the cover 111, and then pass tungsten powder and other materials into the mixing barrel 1 through the feed pipe 11, install the cover 111, and then start the first motor 211 and the stirring mechanism 4. The stirring mechanism 4 includes a linkage disk 41 that matches the cross-section of the mixing barrel 1, and the tail end of the linkage disk 41 is provided with a plurality of spiral stirring rods 42 arranged at equal angles along its circumference. The spiral direction of the spiral stirring rods 42 is opposite to that of the spiral plate 14. The head end of the linkage disk 41 is provided with a linkage shaft 43, and the head end of the mixing barrel 1 is provided with a first rotating seat 44. The outer side wall of the rotating disk 23 is provided with a second rotating seat 232 coaxial with the first rotating seat 44. The linkage disk 41 is slidably arranged in the mixing barrel 1, and the head end of the spiral plate 14 is in contact with the tail end of the linkage disk 41. The linkage shaft 43 is rotatably arranged on the first rotating seat 44 and the second rotating seat 232, and the linkage shaft 43 is connected to the transmission member.

[0038] The transmission member is a transmission gear ring 7 . A bevel gear 431 is provided at one end of the linkage shaft 43 . The transmission gear ring 7 is arranged on the inner side wall of the mounting seat 21 . The bevel gear 431 is meshed with the transmission gear ring 7 .

[0039] The first motor 211 drives the first rotating shaft 22 to rotate, and the first rotating shaft 22 drives the two rotating disks 23 to rotate. The inclined mixing drum 1 rotates around the axis of the first rotating shaft 22, and the high and low end positions of the mixing drum 1 are continuously reversed. The linkage rotating shaft 43 and the bevel gear 431 also rotate around the axis of the first rotating shaft 22 with the mixing drum 1. Since the transmission gear ring 7 is engaged with the bevel gear 431, the bevel gear 431 rotates while the mixing drum 1 rotates. The bevel gear 431 drives the linkage rotating shaft 43 and the linkage disk 41 to rotate, and the linkage disk 41 drives all the spiral stirring rods 42 to rotate, so that the tungsten powder and other materials in the mixing drum 1 are subjected to two-axis mixing and stirring driving forces.

[0040] Furthermore, two mixing cylinders 1 are provided, and the two mixing cylinders 1 are respectively arranged on both sides of the first rotating shaft 22, and the inclination directions of the two mixing cylinders 1 are opposite, which can improve the balance and invisibly improve the efficiency of tungsten powder processing.

[0041] While the first motor 211 and the stirring mechanism 4 are working, the driving mechanism 5 also starts to work. The driving mechanism 5 includes two first guide rods 51, a second rotating shaft 52 and a second motor 53. An eccentric cam 54 is provided in the middle of the second rotating shaft 52, and a pulling rod 55 is hinged on the eccentric cam 54. Four guide seats 24 distributed in a rectangular shape and guided and matched with the first guide rods 51 are provided at the bottom of the bottom plate 2, wherein a hinge shaft 241 is provided between two guide seats 24, a movable window 31 is provided at the top of the bottom frame 3, the two first guide rods 51 are symmetrically arranged in the bottom frame 3, the second rotating shaft 52 is horizontally rotatably arranged in the middle of the bottom frame 3, and the axis of the second rotating shaft 52 is perpendicular to the axis of the first guide rod 51. The second motor 53 is arranged on the outer wall of the bottom frame 3, and the output end of the second motor 53 is fixedly connected to one end of the second rotating shaft 52, and one end of the pulling rod 55 is hingedly set on the hinge shaft 241.

[0042] The second motor 53 drives the second rotating shaft 52 to rotate, and the second rotating shaft 52 drives the eccentric cam 54 to rotate synchronously around the axis of the second rotating shaft 52. The eccentric cam 54 can pull one end of the pulling rod 55 to rotate around the axis of the second rotating shaft 52, and the other end of the pulling rod 55 can drive the hinge shaft 241 to move. Since the hinge shaft 241 is fixed on two of the guide seats 24, the hinge shaft 241 can drive the two guide seats 24 to move synchronously, that is, the guide seats 24 can move back and forth left and right on the first guide rod 51, and these two guide seats 24 drive the bottom plate 2 to move back and forth left and right synchronously, and the mixing barrel 1 also moves back and forth left and right with the bottom plate 2, so that the tungsten powder and other materials can be subjected to three-axial mixing and stirring driving force, which not only improves the mixing effect of the tungsten powder, but also improves the mixing efficiency of the tungsten powder.

[0043] After mixing is completed, when the feed pipe 11 on the mixing cylinder 1 is at the high end of the mixing cylinder 1, the first motor 211 stops working, and then the solenoid valve 121 opens, so that the mixed tungsten powder can be discharged from the discharge hopper 12, and then the driving mechanism 5 and the knocking mechanism 6 cooperate to prevent the mixed tungsten powder from being retained in the mixing cylinder 1.

[0044] The knocking mechanism 6 includes two knocking components, which are symmetrically arranged on both sides of the bottom plate 2. The knocking components include a synchronous vertical plate 61, a stand 62, a transmission component 63 for driving the synchronous vertical plate 61 to always move backward, and a separation component 64 for driving the synchronous vertical plate 61 to separate from the transmission component 63. A rubber knocking column 611 is provided on the outer wall of the upper end of the front part of the synchronous vertical plate 61, and two symmetrically arranged second guide rods 612 are provided on the back of the synchronous vertical plate 61. The tail ends of the two second guide rods 612 are provided with limit plates 613. A spring 614 is sleeved on one of the second guide rods 612, and two symmetrically arranged guide holes are provided on the stand 62. The two second guide rods 612 are respectively slidably arranged in the two guide holes. The two ends of the spring 614 are respectively fixedly connected to the stand 62 and the limit plate 613. The stand 62, the transmission component 63 and the disengagement component 64 are all arranged on the top of the bottom frame 3, and the transmission component 63 and the disengagement component 64 are respectively located on both sides of the stand 62. The second rotating shaft 52 and the synchronous vertical plate 61 are both transmission-connected to the transmission component 63.

[0045] The transmission component 63 includes a transmission shaft 631, a transmission disk 632, a worm wheel 633 and a worm 634. The top of the transmission disk 632 is provided with four abutment columns 6321 arranged at equal angles along its circumference. A third rotating seat 32 is provided on the inner top wall of the bottom frame 3. The lower end of the back of the synchronous vertical plate 61 is provided with an L-shaped driven rod 615 abutting and cooperating with the abutment column 6321. The transmission shaft 631 is arranged on the third rotating seat 32 for vertical rotation. The bottom of the transmission disk 632 is fixedly connected to the top of the transmission shaft 631. The worm wheel 633 is fixedly connected to the bottom of the transmission shaft 631. The worm 634 is arranged on the second rotating shaft 52, and the worm 634 is meshed with the worm wheel 633.

[0046] The disengagement component 64 includes an L-shaped bracket 641, a pushing cylinder 642 and a disengagement rod 643. A sliding groove is provided on the inner top wall of the L-shaped bracket 641, a connecting plate 644 is provided on the side wall of the disengagement rod 643, a sliding block 645 is provided on the top of the disengagement rod 643, a first wedge surface 6431 is provided at one end of the disengagement rod 643, a second wedge surface 616 matching the first wedge surface 6431 is provided on one side of the synchronous vertical plate 61, the pushing cylinder 642 is fixedly connected to the inner top wall of the L-shaped bracket 641, the sliding block 645 is slidably set in the sliding groove, and the output end of the pushing cylinder 642 is fixedly connected to the connecting plate 644.

[0047] The disengagement component 64 works first, and the push cylinder 642 drives the disengagement rod 643 to move, so that the disengagement rod 643 gradually moves away from the synchronous vertical plate 61, and the synchronous vertical plate 61 gradually loses the limit of the disengagement rod 643. The elastic force of the spring 614 can pull the limit plate 613 to move forward, and the limit plate 613 drives the two second guide rods 612 to move forward synchronously. The two second guide rods 612 drive the synchronous vertical plate 61 to move forward, and the synchronous vertical plate 61 drives the L-shaped driven rod 615 to move forward synchronously. The L-shaped driven rod 615 can hit an abutment column 6321 on the transmission plate 632, and then the second motor 53 works to drive the second rotating shaft 52 to rotate, and then the bottom The plate 2 can reciprocate left and right, and the second rotating shaft 52 can drive the worm 634 to rotate synchronously after rotating, and the worm 634 drives the worm wheel 633 to rotate, and the worm wheel 633 drives the transmission rotating shaft 631 and the transmission plate 632 to rotate, and all the abutment columns 6321 rotate synchronously with the transmission plate 632. When the abutment column 6321 rotates, it can abut against the L-shaped driven rod 615 to move backward, and the rubber knocking column 611 can be away from the mixing cylinder 1. The spring 614 is stretched, and the abutment column 6321 can gradually separate from the L-shaped driven rod 615 as the transmission plate 632 rotates. After the L-shaped driven rod 615 separates from the abutment column 6321, The elastic force of the spring 614 drives the synchronous vertical plate 61 and the L-shaped driven rod 615 to move forward, and the L-shaped driven rod 615 can hit the next abutting column 6321. At this time, the rubber knocking column 611 also hits the outer wall of the mixing cylinder 1, and the abutting column 6321 drives the L-shaped driven rod 615 to move backward. In this cycle, the rubber knocking column 611 can continuously knock on the mixing cylinder 1, and the mixed tungsten powder in the mixing cylinder 1 can be subjected to the left and right reciprocating translation driving force and the continuous knocking force, so that the mixed tungsten powder can be completely discharged from the mixing cylinder 1 to avoid the occurrence of retention. After the mixed tungsten powder in the mixing cylinder 1 is exhausted, the second The motor 53 stops working. At this time, the L-shaped follower rod 615 and the abutment column 6321 are about to disengage. Then the push cylinder 642 drives the disengagement rod 643 to move in the opposite direction. The second wedge surface 616 on the disengagement rod 643 abuts against the first wedge surface 6431 of the synchronous vertical plate 61. Through the cooperation of the first wedge surface 6431 and the second wedge surface 616, the synchronous vertical plate 61 continues to move backward, and the L-shaped follower rod 615 moves backward synchronously therewith. The L-shaped follower rod 615 moves away from the abutment column 6321, so that the abutment column 6321 can no longer abut against the L-shaped follower rod 615, that is, when the mixing barrel 1 is performing a mixing operation, the knocking mechanism 6 does not work.
