Abstract

This invention discloses a split-type powder mixer, relating to the technical field of powder mixers. It includes a mixing motor, with a motor coupling fixedly connected to the output end of the motor. A mixing rod is fixedly connected to the bottom of the motor coupling. A fixing mechanism is fixedly connected to the inner wall of the motor coupling, and an inner support mechanism is fixedly connected to the bottom of the fixing mechanism. By providing the inner support mechanism, this invention effectively reduces the eccentricity between the motor shaft and the mixing component shaft, thereby improving mixing efficiency and quality. Specifically, before the mixing rod is fixed to the motor coupling, the inner wall of the coupling disc contacts the outer wall of the push column. The push column rises with the coupling disc, causing the sliding column to slide along the cylindrical rod. The upward movement of the sliding column causes the hinge block and hinge rod to rotate, thereby causing the inner support plate to unfold outwards. After the inner support plate is fully unfolded, it adheres tightly to the inner wall of the coupling disc, providing stable support and ensuring the stability of the mixing rod during high-speed rotation.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. This application, by setting an internal support mechanism, can effectively reduce the eccentricity between the mixing motor shaft and the mixing component shaft, thereby improving mixing efficiency and mixing quality. Specifically, before the mixing rod is fixed by the motor coupling, the inner wall of the coupling disc contacts the outer wall of the push column. The push column rises with the coupling disc, driving the sliding column to slide along the cylindrical rod. The upward movement of the sliding column causes the hinge block and hinge rod to rotate, thereby causing the internal support plate to unfold outward. After the internal support plate is fully unfolded, it is tightly attached to the inner wall of the coupling disc, providing stable support force and ensuring the stability of the mixing rod when it rotates at high speed. This design improves the efficiency of the mixer, enhances the durability and reliability of the equipment, and ensures the uniformity and quality of the mixture.

[0019] 2. This application, through the installation of a fixing mechanism, uses a sliding rod located at the center of the top of the inner wall of the motor coupling. The cooperation of the sliding frame and hydraulic push rod enables precise alignment between the mixing motor shaft and the mixing component shaft, further ensuring the stability of the mixing process. Specifically, when connecting the mixing rod, the top of the coupling is inserted into the inner wall of the motor coupling. The operator activates the hydraulic push rod, causing the sliding frame and push plate to slide upwards along the sliding rod, moving the hinge block and rotating rod upwards. The expansion rod slides within the groove, and the connecting block and clamping plate move inwards, engaging the fixing groove of the coupling plate, thus achieving a tight connection between the motor coupling and the mixing rod. The entire process is controlled by a hydraulic system, ensuring a stable and precise connection. After connection, the mixer can begin operation, with the mixing rod rotating at high speed under motor drive, mixing and dispersing powder materials.

[0020] 3. This application, by setting up a stirring rod coupling and a coupling disc, makes the connection between the stirring rod and the motor coupling more secure, while facilitating maintenance and replacement, and improving the service life of the mixer;

[0021] 4. This application, by setting an internal support linkage mechanism, not only enhances the structural stability of the mixer, but also provides additional support force during the mixing process, ensuring the smooth progress of the mixing process. Attached Figure Description

Detailed Implementation

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments 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.

[0034] Example: Figures 1-3 As shown, the present invention provides a technical solution for a split-type powder mixer, including a stirring motor 1, a motor coupling 2 fixedly connected to the output end of the stirring motor 1, a stirring rod 3 fixedly connected to the bottom of the motor coupling 2, a fixing mechanism 4 fixedly connected to the inner wall of the motor coupling 2, and an inner support mechanism 5 fixedly connected to the bottom of the fixing mechanism 4.

[0035] Please see Figure 4-7The fixing mechanism 4 includes a fixing plate 41. A slide rod 42 is fixedly connected to the top center of the fixing plate 41. The top end of the slide rod 42 is fixedly connected to the top center of the inner wall of the motor coupling 2. The top of the fixing plate 41 has a ring array of sliding grooves 43. The outer wall of the fixing plate 41 is hollowed out on one side, which is aligned with the multiple sliding grooves 43. A slide frame 44 is slidably connected to the outer wall of the slide rod 42. Hydraulic push rods 45 are fixedly connected to the top two sides of the slide frame 44. The top ends of the two hydraulic push rods 45 are fixedly connected to the top two sides of the inner wall of the motor coupling 2. A push plate 46 is fixedly connected to the bottom of the outer wall of the slide frame 44. A hinge block 47 is fixedly connected to the outer wall of the push plate 46 in a ring array. Rotating rods 48 are rotatably connected to the inner walls of multiple hinge blocks 47. Expanding rods 49 are rotatably connected to the side of multiple rotating rods 48 away from the hinge blocks 47. The outer walls of multiple expanding rods 49 are slidably connected to the slide rods 44. The stirring rod 3 is connected to the inner wall of the chute 43. The outer ends of the multiple expanding rods 49 extend to the outer wall of the fixed plate 41. The outer ends of the multiple expanding rods 49 are fixedly connected to the connecting blocks 410. The inner bottom of the multiple connecting blocks 410 extends to the bottom of the outer wall of the fixed plate 41. The inner bottom of the multiple connecting blocks 410 is fixedly connected to the clamping plate connecting rod 411. The inner side of the multiple clamping plate connecting rod 411 is fixedly connected to the clamping plate 412. The stirring rod 3 includes a stirring rod body 31. The top of the stirring rod body 31 is fixedly connected to the stirring rod coupling 32. The top of the stirring rod coupling 32 is fixedly connected to the coupling disc 33. The inner wall of the coupling disc 33 is hollow. The outer wall of the coupling disc 33 is provided with a ring array of fixing grooves 34. The outer wall of the coupling disc 33 is movably connected to the bottom of the fixed plate 41. The inner walls of the multiple fixing grooves 34 are movably connected to the outer walls of the multiple clamping plates 412 respectively.

[0036] When connecting the stirring rod 3, the top coupling plate 33 of the stirring rod coupling 32 must first be inserted into the inner side of the multiple clamping plates 412 at the bottom of the inner wall fixing plate 41 of the motor coupling 2. To complete this connection, the operator needs to activate two hydraulic push rods 45. After activation, these two hydraulic push rods 45 will pull the slide 44 upward along the outer wall of the slide rod 42. As the slide 44 slides upward, it will drive the push plate 46 and the multiple hinge blocks 47 on the outer wall to move upward simultaneously. The upward movement of the hinge blocks 47 will further pull the rotating rod 48, causing the side of the rotating rod 48 away from the hinge blocks 47 to pull the expansion and contraction rod. The expansion rod 49 slides on the inner wall of the multiple grooves 43 opened on the fixed plate 41, and slides inward, thereby pulling the connecting block 410 to drive the clamping plate connecting rod 411 and the inner clamping plate 412 to move inward. The multiple clamping plates 412 move inward and finally get into the inner wall of the multiple fixed grooves 34 opened on the outer wall of the coupling plate 33. Through this process, the motor coupling 2 and the stirring rod 3 achieve a tight connection. The entire connection process is controlled by the hydraulic system, which ensures the stability and accuracy of the connection. After the connection is completed, the mixer can start working. The stirring rod 3 rotates at high speed under the drive of the motor to mix and disperse the powder material.

[0037] Please see Figure 7-10 The internal support mechanism 5 includes a cylindrical rod 51. An internal support linkage mechanism 52 is movably connected to the outer wall of the cylindrical rod 51 in a ring array. The cylindrical rod 51 includes a top column 511. A top column hinge block 512 is fixedly connected to the middle of the outer wall of the top column 511 in a ring array. A sliding column 513 is slidably connected to the bottom of the outer wall of the top column 511. A sliding column hinge block 514 is fixedly connected to the outer wall of the sliding column 513 in a ring array. A push column 515 is fixedly connected to the bottom of the sliding column 513. Each of the multiple internal support linkage mechanisms 52 includes an internal support plate 521. The top and bottom of the inner sides of the multiple internal support plates 521 are fixedly connected by hinges. The rod connecting block 522 has multiple hinge rod connecting blocks 522 at the top, each with a hinge rod 523 rotatably connected to its outer wall. Multiple hinge rod connecting blocks 522 at the bottom have multiple hinge rod connecting blocks 522 at the outer wall rotatably connected to a second hinge rod 524. The outer middle of multiple hinge rods 523 is rotatably connected to the inner middle of the second hinge rod 524. The inner wall of multiple hinge rods 523 on the side away from the top hinge rod connecting block 522 is rotatably connected to the outer wall of the sliding column hinge block 514. The inner wall of multiple second hinge rods 524 on the side away from the bottom hinge rod connecting block 522 is rotatably connected to the outer wall of the top column hinge block 512.

[0038] Before the stirring rod 3 is connected to the motor coupling 2 and fixed by the fixing mechanism 4, the inner wall of the coupling disc 33 is first connected to the outer wall of the push column 515. While the coupling disc 33 continues to move upward, it drives the push column 515 to move upward on the outer wall of the top column 511. At this time, the sliding column 513 slides upward along the outer wall of the cylindrical rod 51 under the push of the push column 515. The upward movement of the sliding column 513 drives the sliding column hinge block 514 to move upward. Since the sliding column hinge block 514 is rotated and connected to the hinge rod 523, the hinge rod 523 rotates upward. The upper end of the hinge rod 523 is connected to the hinge rod connecting block 522 of the inner support plate 521. Therefore, the inner support plate 521 will also unfold outward with the rotation of the hinge rod 523.

[0039] As the inner support plates 521 unfold, they will be tightly supported against the inner wall of the coupling disk 33. After the inner support plates 521 are fully unfolded and tightly attached to the inner wall of the coupling disk 33, the entire inner support mechanism 5 can provide sufficient support force to ensure the stability of the stirring rod 3 when rotating at high speed. This design not only improves the working efficiency of the mixer, but also greatly enhances the durability and reliability of the equipment. Due to the supporting effect of the inner support plates 521, the stirring rod 3 will not deviate or shake during operation, thereby ensuring the uniformity and quality of the mixture.

[0040] In addition, the design of the inner support mechanism 5 also takes into account the convenience of maintenance and replacement. When it is necessary to inspect or replace the stirring rod 3, the operator can easily separate the stirring rod 3 from the motor coupling 2 by retracting the inner support plate 521 through a simple operation. This design greatly reduces the time and labor intensity required for maintenance and improves the efficiency of the mixer.

[0041] Working principle: When connecting the stirring rod 3, the top coupling plate 33 of the stirring rod coupling 32 needs to be inserted into the inner side of the multiple clamping plates 412 at the bottom of the inner wall fixing plate 41 of the motor coupling 2. To complete this connection, the operator needs to activate two hydraulic push rods 45. After activation, these two hydraulic push rods 45 will pull the slide 44 upward along the outer wall of the slide rod 42. As the slide 44 slides upward, it will drive the push plate 46 and the multiple hinge blocks 47 on the outer wall to move upward simultaneously. The upward movement of the hinge blocks 47 will further pull the rotating rod 48, causing the side of the rotating rod 48 away from the hinge blocks 47 to pull the retractor. The expanding rod 49 slides on the inner wall of the multiple grooves 43 opened on the fixed plate 41. The retracting expanding rod 49 slides inward, thereby pulling the connecting block 410 to drive the clamping plate connecting rod 411 and the inner clamping plate 412 to move inward. The multiple clamping plates 412 move inward and finally get into the inner wall of the multiple fixed grooves 34 opened on the outer wall of the coupling plate 33. Through this process, the motor coupling 2 and the stirring rod 3 achieve a tight connection. The entire connection process is controlled by the hydraulic system, which ensures the stability and accuracy of the connection. After the connection is completed, the mixer can start working. The stirring rod 3 rotates at high speed under the drive of the motor to mix and disperse the powder material.

[0042] Before the stirring rod 3 is connected to the motor coupling 2 and fixed by the fixing mechanism 4, the inner wall of the coupling disc 33 first connects to the outer wall of the push column 515. As the coupling disc 33 continues to move upward, it drives the push column 515 to move upward along the outer wall of the top column 511. At this time, the sliding column 513 slides upward along the outer wall of the cylindrical rod 51 under the push of the push column 515. The upward movement of the sliding column 513 drives the sliding column hinge block 514 to move upward. Due to the rotation of the sliding column hinge block 514 and the hinge rod 523... Upon connection, the hinge rod 523 rotates upward, and its upper end connects to the hinge rod connecting block 522 of the inner support plate 521. Therefore, the inner support plate 521 also expands outward as the hinge rod 523 rotates. Before the stirring rod 3 is connected to the motor coupling 2 and fixed by the fixing mechanism 4, the inner wall of the coupling disc 33 first connects to the outer wall of the push column 515. As the coupling disc 33 continues to move upward, it drives the push column 515 to move upward on the outer wall of the top column 511. At this time... Pushed by the pusher 515, the sliding column 513 slides upward along the outer wall of the cylindrical rod 51. The upward movement of the sliding column 513 causes the sliding column hinge block 514 to move upward. Due to the rotational connection between the sliding column hinge block 514 and the hinge rod 523, the hinge rod 523 rotates upward accordingly. The upper end of the hinge rod 523 is connected to the hinge rod connecting block 522 of the inner support plate 521. Therefore, the inner support plate 521 will also unfold outward with the rotation of the hinge rod 523. As the inner support plate 521 unfolds, it will be tightly supported against the inner wall of the coupling disk 33. After the inner support plate 521 is fully unfolded and tightly attached to the inner wall of the coupling disk 33, the entire inner support mechanism 5 can provide sufficient support force to ensure the stability of the stirring rod 3 when rotating at high speed. This design not only improves the working efficiency of the mixer, but also greatly enhances the durability and reliability of the equipment. Due to the supporting effect of the inner support plate 521, the stirring rod 3 will not deviate or shake during operation, thus ensuring the uniformity and quality of the mixture.
