Technical Field
[0001] This utility model belongs to the field of maintenance technology for mixer drive motors, specifically relating to a rotary maintenance mechanism for mixer drive motors. Background Technology
[0002] A mixer is a mechanical device used to uniformly mix two or more materials, widely used in the food, chemical, and pharmaceutical industries. Based on the container's motion, it can be divided into fixed-container and rotary-container types. Rotary-container mixers use the rotation of the container to tumble and mix the materials, resulting in high mixing uniformity but a longer mixing time; fixed-container mixers use internal agitators for mixing, offering higher efficiency. Based on the operation method, it can be divided into continuous and intermittent types. Continuous mixers are suitable for large-scale production, offering high efficiency but poor adaptability; intermittent mixers provide good mixing quality and are suitable for small-batch, multi-variety production. Based on the working principle, it can be divided into gravity mixers and forced mixers. Gravity mixers rely on the material's own gravity for mixing, while forced mixers use external mechanical force (such as ribbons or paddles) to force mixing. Currently, mixers suitable for large-scale mixing typically have a drive mechanism and mixing blades located at the top of the mixing drum. However, for mixing highly viscous materials, the main technical problem with top-rotating mixers is the limited mixing torque, and the top-stirring method easily causes vibration in the mixer. Therefore, the improved mixer currently employs a drive mechanism located at the bottom of the mixer. A slewing bearing causes the mixing drum to rotate, while a vertical stirring paddle is positioned at the top. As the stirring paddle rotates, the mixing drum rotates in coordination, achieving high-torque mixing of materials with high viscosity. This solves the problems of insufficient stirring torque and vibration associated with a drive mechanism located at the top of the mixing drum.
[0003] In existing technologies, a drive mechanism is located at the bottom of the mixer. Typically, a motor and a reducer generate a large rotational torque, which drives the mixing drum to rotate through the meshing of a drive gear and the outer ring gear of the slewing bearing. This, combined with the stirring device at the top of the mixer, achieves the mixing of materials with high viscosity. The meshing position of the drive gear and the outer ring gear of the slewing bearing is fixed (i.e., the positions of the motor and reducer are fixed). The main technical problem with this is that when the motor or reducer malfunctions and requires maintenance, both the motor and reducer must be disassembled simultaneously for repair. This disassembly process is time-consuming, extending the maintenance cycle and directly affecting the normal mixing operation of the mixer. Based on the above-mentioned technical deficiencies in existing technologies, the inventor has developed a rotary maintenance mechanism for the mixer drive motor, which effectively solves the aforementioned technical problems. Utility Model Content
[0004] To address the aforementioned technical problems, this invention provides a rotary maintenance mechanism for a mixer drive motor. The mechanism features a simple, scientifically designed structure. This invention solves the problem of lengthy disassembly times for the motor or reducer, which prolongs maintenance cycles and directly affects the normal mixing operation of the mixer.
[0005] The technical solution adopted by this utility model is as follows: a rotary maintenance mechanism for a mixer drive motor, including a mixer, a rotary bearing, and a rotating shaft; a rotary bearing is provided at the center of the bottom of the mixing drum of the mixer, the outer ring of the rotary bearing is fixed to the bottom of the mixing drum of the mixer, and the inner ring of the rotary bearing is fixed to the upper part of the protrusion; the protrusion is fixedly located at the center of the bottom of the mixer support; the skirt is ring-shaped, the bottom of the skirt is fixedly located on the mixer support, the protrusion is fixedly located at the upper part of the skirt, and the mixing drum of the mixer is placed in the protrusion; a first fixing ring is located at the lower part of the skirt, and the skirt and the first fixing ring are fixedly connected by a connecting post; a second fixing ring is located at the lower part of the first fixing ring, and the second fixing ring and the first fixing ring are fixedly connected by a connecting post. The following are the components: an arc-shaped groove is located on the front left side of the first fixed ring, running through the upper and lower parts of the first fixed ring; a reducer is installed at the right end of the motor, with the drive shaft fixed on the power output shaft of the reducer and the drive gear fixed on the upper end of the drive shaft; the support plate is square and fixed on the front side of the reducer; the tie rod connecting plate is symmetrically fixed on the front side of the support plate, with the tie rod vertically fixed in the middle of the symmetrically fixed tie rod connecting plate, and a gap is reserved between the tie rod and the support plate; the first limiting hole is symmetrically opened on the lower tie rod connecting plate, and the limiting screw is engaged and tightened in the first limiting hole; the second limiting hole is symmetrically opened on the upper left side of the second fixed ring, and the second limiting hole is inclined to the left and right.
[0006] The inner diameter of the convex ring is larger than the inner diameter of the skirt plate, and the inner diameter of the convex ring is larger than the outer diameter of the mixing cylinder of the mixer.
[0007] The connecting columns that are fixedly connected between the skirt plate, fixing ring one, and fixing ring two are evenly arranged at equal angles around the circumference of the skirt plate, fixing ring one, and fixing ring two.
[0008] The motor's power output shaft is fixedly connected to the reducer's power input shaft, and the motor is fixedly connected to the power supply via a control switch using wires.
[0009] The height of the support plate is equal to the distance between the first fixing ring and the second fixing ring.
[0010] The inner walls of the first limiting hole and the second limiting hole are provided with internal threads.
[0011] The distance from the circular points of the first and second limiting holes to the tip circle of the slewing bearing teeth is equal to the diameter of the drive gear.
[0012] The working process of this rotary maintenance mechanism for the mixer drive motor is as follows: When the motor malfunctions and requires maintenance, the operator first loosens the limit screw, disengaging it from the second limit hole. The operator then pulls the lever forward, causing the drive shaft to rotate along the arc of the arc groove towards the forward position. Simultaneously, the top surface of the drive gear disengages from the top surface of the outer ring gear of the slewing bearing. This continues until the motor, reducer, and support plate are rotated to the front position of the first and second fixed rings, thus enabling maintenance of the motor or reducer. After the motor or reducer is repaired, to re-engage the drive gear with the outer ring gear of the slewing bearing, the operator repeats the reverse action. Once the drive gear is engaged with the outer ring gear, the operator tightens the limit screw, which passes through the first and second limit holes to fix the support plate in place.
[0013] The beneficial effects of this utility model are as follows: by setting up an arc groove, a motor, a reducer, a drive shaft, a drive gear, a support plate, a tie rod connecting plate, a tie rod, a first limiting hole, a limiting screw, and a second limiting hole, the motor and reducer can rotate under the sliding cooperation of the support plate, the drive shaft, and the arc groove. This improves the speed of troubleshooting motor or reducer failures and shortens the maintenance cycle without disassembling the motor or reducer. Attached Figure Description

[0018] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.
[0019] This utility model provides a rotary maintenance mechanism for a mixer drive motor:
[0020] like Figure 1As shown in Figure 2, a slewing bearing 2 is provided at the center of the bottom of the mixing cylinder of the mixer 1. The outer ring of the slewing bearing 2 is fixed to the bottom of the mixing cylinder of the mixer 1, and the inner ring of the slewing bearing 2 is fixed to the upper part of the protrusion 3. The protrusion 3 is fixedly located at the center of the bottom of the support of the mixer 1. The skirt plate 5 is ring-shaped. The bottom of the skirt plate 5 is fixedly located on the support of the mixer 1, and the protrusion ring 4 is fixedly located on the upper part of the skirt plate 5. The mixing cylinder of the mixer 1 is placed in the protrusion ring 4. The inner diameter of the protrusion ring 4 is larger than the inner diameter of the skirt plate 5, and the inner diameter of the protrusion ring 4 is larger than the outer diameter of the mixing cylinder of the mixer 1.
[0021] The above structure is inherent to the mixer 1 itself and falls entirely within the scope of existing technology, which is fully known to those skilled in the art.
[0022] The above-mentioned arrangement of the slewing bearing 2, driven by the motor 9, reducer 10, drive shaft 11 and drive gear 12, and through the meshing transmission between the outer ring teeth of the slewing bearing 2 and the drive gear 12, enables the mixing cylinder of the mixer 1 to rotate inside the convex ring 4.
[0023] like Figure 1 or Figure 2 As shown, fixing ring 1 6 is located at the lower part of skirt plate 5, and skirt plate 5 and fixing ring 1 6 are fixedly connected by connecting post; fixing ring 2 7 is located at the lower part of fixing ring 1 6, and fixing ring 2 7 and fixing ring 1 6 are fixedly connected by connecting post.
[0024] The above-mentioned skirt 5, fixing ring 1 6, fixing ring 2 7 and connecting column can fix the skirt 5, fixing ring 1 6 and fixing ring 2 7 into an integral structure; on the one hand, it provides an installation platform for motor 9, reducer 10 and drive shaft 11; on the other hand, it plays a fixed support role for motor 9, reducer 10, drive shaft 11 and drive gear 12.
[0025] like Figure 1 or Figure 2 As shown, the arc-shaped groove 8 is located on the front left side of the fixed ring 6, and the arc-shaped groove 8 runs through the upper and lower bodies of the fixed ring 6. The arc-shaped groove 8 provides a sliding track for the rotary movement of the drive shaft 11, which serves as a guide. On the other hand, it reduces the rotary movement resistance of the drive shaft 11 during the sliding process.
[0026] like Figure 1 or Figure 2As shown, a reducer 10 is provided at the right end of the motor 9, and the drive shaft 11 is fixedly mounted on the power output shaft of the reducer 10. The drive gear 12 is fixedly mounted on the upper end of the drive shaft 11. The main purpose of this arrangement is to increase the rotational torque of the drive shaft 11 by using the motor 9 as the driving force through the meshing of the speed-changing gear of the reducer 10, and then drive the stirring paddle in the mixer 1 to rotate through the meshing of the drive gear 12 with the slewing bearing 2.
[0027] like Figure 1 As shown in Figure 2, the support plate 13 is a square plate and is fixedly installed on the front side of the reducer 10; the height of the support plate 13 is equal to the distance between the first fixed ring 6 and the second fixed ring 7.
[0028] The aforementioned support plate 13, through its contact engagement with the first fixing ring 6 and the second fixing ring 7, can support the motor 9 and the reducer 10 in a horizontal state. On one hand, it serves to support the motor 9, the reducer 10, the drive shaft 11, and the drive gear 12. On the other hand, through the sliding engagement between the support plate 13, the drive shaft 11, and the arc-shaped groove 8, it enables the motor 9 and the reducer 10 to rotate. Furthermore, it provides a fixed installation position for fixing the tie rod connecting plate 14 and the tie rod 15.
[0029] like Figure 1 , 2 As shown in Figure 3, the tie rod connecting plate 14 is symmetrically fixed on the front side of the support plate 13, and the tie rod 15 is vertically fixed in the middle of the symmetrically fixed tie rod connecting plate 14. A gap is reserved between the tie rod 15 and the support plate 13. The first limiting hole 16 is symmetrically opened on the lower tie rod connecting plate 14, and the limiting screw 17 is engaged and tightened in the first limiting hole 16. The second limiting hole 18 is symmetrically opened on the upper left side of the second fixing ring 7, and the second limiting hole 18 is inclined to the left and right.
[0030] The aforementioned arrangement of the tie rod connecting plate 14, tie rod 15, limiting hole one 16, limiting screw 17, and limiting hole two 18 provides the operator with a gripping point for the motor 9, reducer 10, drive shaft 11, and drive gear 12 to rotate. On the other hand, the setting of the limiting screw 17 with the limiting hole one 16 and limiting hole two 18 can limit and fix the drive gear 12 to the position where it meshes with the slewing bearing 2.
[0031] like Figure 1-3As shown, the working process of this rotary maintenance mechanism for the mixer drive motor is as follows: When the motor 9 malfunctions and needs maintenance, the operator first loosens the limit screw 17, and the limit screw 17 leaves the limit hole 18. At this time, the operator holds the pull rod 15 and pulls it forward. At this time, the drive shaft 11 rotates along the arc surface of the arc groove 8 to the front position. At the same time, the tooth tip surface of the drive gear 12 disengages from the meshing with the tooth tip surface of the outer ring of the slewing bearing 2. Finally, the motor 9, the reducer 10 and the support plate 13 are rotated to the front position of the fixed ring 6 and the fixed ring 7, so as to realize the fault maintenance operation of the motor 9 or the reducer 10. After the maintenance of motor 9 or reducer 10 is completed, when the operator needs to re-engage the drive gear 12 with the outer ring teeth of the slewing bearing 2, the above-mentioned reverse action can be repeated. After the drive gear 12 engages with the outer ring teeth of the slewing bearing 2, the operator tightens the limit screw 17. The limit screw 17 passes through the limit hole 16 and the limit hole 18 to fix and limit the support plate 13.
[0032] Various modifications to the above embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
