Description

Technical Field

[0001] This utility model belongs to the field of continuous stirring technology of stirring paddles, and specifically relates to a continuous stirring paddle motor connection structure. Background Technology

[0002] Mixing devices are widely used in chemical, food, pharmaceutical, and building materials industries. In actual production processes, it is often necessary to maintain the continuous operation of the mixing paddle for extended periods to ensure uniform mixing of materials and stability of the process. Existing mixing equipment generally uses a single motor to drive the mixing rod, with the motor transmitting power through an output shaft and transmission gears or couplings. However, in long-cycle production environments, if the main motor fails or experiences a malfunction that cannot be immediately repaired, the mixing device will be unable to continue operating, forcing a production interruption and impacting production efficiency and product quality.

[0003] To mitigate downtime risks, some equipment has pre-installed motor mounting locations on the exterior of the frame for motor replacement in case of failure. However, these structures generally require complete disassembly of the coupling, drive shaft, or stirring rod, which is time-consuming and cumbersome, hindering the rapid restoration of stirring functionality in emergencies. Furthermore, most mixing equipment currently lacks effective backup power switching mechanisms. Even when a backup motor is provided, professional personnel are often required to disassemble transmission components to complete the power switch, making it difficult to deploy the backup motor promptly.

[0004] Especially in continuous and batch production scenarios, the shutdown of the agitator often leads to material stratification, agglomeration, or process interruption. Enterprises urgently need a motor connection structure that can quickly switch over when the main motor fails, while ensuring continuous agitation. However, existing technologies generally lack a structural design that allows the backup motor to quickly engage with the agitator drive system through simple operation. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide a continuous stirring paddle motor connection structure, which can quickly replace the main motor and realize the continuous operation of the stirring rod.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A continuous stirring paddle motor connection structure includes a flange, a stirring rod, a slide rod, and a switching gear. A flange bearing is installed inside the flange, and the inner ring of the flange bearing is nested and fixed to the top of the stirring rod. A rod drive gear is nested and fixed after the top of the stirring rod passes through the inner ring of the flange bearing. A meshing chamber is provided on one side of the flange, and the meshing chamber and the flange are an integral structure.

[0008] The upper surface of the meshing chamber is provided with an equipment hole A, a sector window and an equipment hole B, and the two ends of the meshing chamber corresponding to the sector window are respectively provided with a positioning threaded hole group A and a positioning threaded hole group B.

[0009] The main motor is fixed to the position corresponding to equipment hole A in the meshing chamber by screws, and the spare motor is fixed to the position corresponding to equipment hole B in the meshing chamber by screws.

[0010] A gear bearing is installed at the center of the switching gear disc, and the switching gear disc is placed inside the meshing chamber. The top of the slide rod passes through the gear bearing and the fan-shaped window in sequence, and an airfoil sleeve is nested on the top of the slide rod.

[0011] A bolt is installed through the airfoil sleeve and the slide rod, and the airfoil sleeve and the slide rod are fixed together by bolts.

[0012] The two wing plates of the wing sleeve have through holes inside, and the through holes inside the two wing plates of the wing sleeve are correspondingly set with positioning threaded hole group A or positioning threaded hole group B. The wing sleeve is connected and fixed to positioning threaded hole group A or positioning threaded hole group B by screws.

[0013] The main motor's rotor shaft passes through equipment hole A and is then nested and fixedly installed with a main gear. The standby motor's rotor shaft passes through equipment hole B and is then nested and fixedly installed with a standby gear.

[0014] The switching gear and the rod drive gear are meshed together, and the switching gear is also meshed with the main gear or the spare gear.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] In continuous mixing production scenarios, a failure of the main motor can cause the mixing rod to stop operating, leading to problems such as material settling, stratification, or process interruption. The combination of the flange, flange bearing, mixing rod, rod drive gear, and meshing chamber in this structure ensures the integrity and stability of the mixing components even in the event of a main motor failure, avoiding prolonged downtime due to disassembly of transmission components. By designing the flange and meshing chamber as an integrated structure, the support rigidity is enhanced, allowing the meshing chamber to simultaneously accommodate the main gear, spare gear, and switching gear disc. This provides reliable space and a fixed foundation for rapid power switching, ensuring the continuity of the mixing process.

[0017] In traditional mixing equipment, the backup motor often fails to quickly establish a transmission connection, resulting in the inability to restore mixing function within a short time. This structure addresses this by incorporating an equipment hole, a fan-shaped window, and a set of positioning threaded holes at the top of the meshing chamber. These features allow the main and backup motors to be fixedly mounted at the equipment hole location, while the fan-shaped window and positioning threaded holes provide movement and positioning paths for the slide bar and airfoil sleeve. This structure enables the backup motor to quickly resume operation after the main motor fails, reducing delays caused by power switching and improving continuous operation capability.

[0018] To address the issues of inaccurate positioning and unstable meshing in traditional switching mechanisms, this structure utilizes the cooperation of a switching gear, gear bearings, sliding rod, and wing-shaped sleeve to enable accurate switching between the main and spare gears. The engagement of the wing-shaped sleeve with the positioning threaded hole group ensures reliable locking of the sliding rod at different positions, preventing gear misalignment or poor meshing during switching. This guarantees a stable meshing between the switching gear and the rod-driven gear, improving the reliability of power transmission. Attached Figure Description

[0026] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings.

[0027] like Figures 1-4 As shown, the continuous stirring paddle motor connection structure of this utility model includes a flange 101, a stirring rod 102, a slide rod 107, and a switching gear disc 108. During continuous stirring production, the stirring rod 102 must maintain stable operation for a long time; otherwise, the material will experience problems such as settling, stratification, or agglomeration due to machine shutdown. Existing stirring equipment generally uses a single main motor to drive the stirring rod 102, but the main motor 105 is prone to failure after long-term operation due to bearing wear, coil damage, or overload, resulting in the inability to continue stirring and failing to meet the requirements of continuous production. To solve the problems of difficult transmission switching and long maintenance time after the main motor 105 fails, this structure proposes an optimized stirring connection mechanism. A flange bearing 111 is installed inside the flange 101. The inner ring is nested and fixed to the top of the stirring rod 102 to provide stable support for the stirring rod 102 and reduce rotational friction; the top of the stirring rod 102 passes through the inner ring of the flange bearing 111 and is then nested and fixed with a rod drive gear 104, so that the rod drive gear 104 can mesh with the transmission mechanism at the rear end; a meshing chamber 103 is provided on one side of the flange 101, and the meshing chamber 103 and the flange 101 are an integral structure to accommodate transmission components including the switching gear 108, the main gear 151 and the spare gear 161; a protective cover is installed on the outside of the rod drive gear 104 to shield the rod drive gear 104, avoid personnel contact and safety risks, and prevent dust from entering and affecting gear meshing; through the above structural arrangement, the purpose of providing basic support for subsequent motor switching is achieved.

[0028] like Figure 1 and Figure 2 As shown, the upper surface of the meshing chamber 103 is provided with an equipment hole A131, a fan-shaped window 132, and an equipment hole B133. In traditional mixing equipment, the backup power mechanism often cannot be directly installed and switched, which means that when the main motor 105 is damaged, a large number of parts need to be disassembled for repair, and the mixing function cannot be quickly restored. This structure solves the problem of installation difficulty by reserving multiple installation positions inside the meshing chamber 103. The meshing chamber 103 is provided with a positioning threaded hole group A134 and a positioning threaded hole at both ends corresponding to the fan-shaped window 132. Group B135 is used to lock with the through hole of the airfoil sleeve 171, so that the slide rod 107 can apply axial positioning to the switching gear plate 108 at different positions; the sector window 132 is used to provide room for the swing of the slide rod 107 and to provide angular guidance when the switching gear plate 108 switches between the main motor and the standby motor; through the partitioned arrangement of equipment holes A131 and B133, the main motor 105 and the standby motor 106 can be synchronously fixed on the meshing chamber 103 structure, providing a structural basis for subsequent power switching.

[0029] like Figures 1-4As shown, the main motor 105 is fixedly mounted on the meshing chamber 103 at the position corresponding to the equipment hole A131 by screws, and the backup motor 106 is fixedly mounted on the meshing chamber 103 at the position corresponding to the equipment hole B133 by screws. In continuous stirring scenarios, when the main motor 105 is damaged or cannot be repaired immediately, it is difficult for traditional structures to replace the motor in a short time, causing the stirring process to be forced to stop. This structure effectively avoids the problem of long time-consuming motor replacement by fixing the main motor 105 and the backup motor 106. The equipment hole A131 provides a through channel for the rotor shaft of the main motor 105, allowing the main gear 151 to extend into the meshing chamber 103 from the inside to mesh with the switching gear 108. The equipment hole B133 provides an installation position for the rotor shaft of the backup motor 106, allowing the backup gear 161 to quickly enter the meshing state when needed. The main motor 105 is responsible for the power output when the equipment is running normally, and the backup motor 106 can quickly take over the work when the main motor 105 fails, thereby ensuring the continuity of stirring.

[0030] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, a gear bearing 181 is installed at the center of the switching gear disc 108, and the switching gear disc 108 is placed inside the meshing chamber 103. In traditional mixing equipment, due to the lack of a fast switching gear disc structure, the standby motor often cannot quickly establish a power transmission relationship with the mixing rod 102. This structure realizes the rapid switching of the motor output end through the switching gear disc 108. The gear bearing 181 is used to support the switching gear disc 108, so that the switching gear disc 108 can maintain smooth rotation and reduce friction during the meshing switching process. The top of the slide rod 107 passes through the gear bearing 181 and the fan-shaped window 132 in sequence, and a wing-shaped sleeve 171 is nested on the top, so that the slide rod 107 can adjust the angle by rotation, so that the wing-shaped sleeve 171 can achieve corresponding locking with the positioning threaded hole group A134 or the positioning threaded hole group B135. The switching gear disc 108 realizes the rapid switching of the meshing position through the positioning of the slide rod 107, so as to adapt to the different meshing requirements of the main motor 105 and the standby motor 106.

[0031] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, a bolt is installed through the airfoil sleeve 171 and the slide rod 107, and the airfoil sleeve 171 and the slide rod 107 are fixed together by the bolt. In traditional structures, the motor switching mechanism generally lacks a reliable positioning and locking structure, which can easily lead to the switching gear 108 failing to accurately align with the corresponding gear, resulting in incomplete meshing or gear breakage. This structure, through the structural arrangement of the two wings of the airfoil sleeve 171, allows the airfoil sleeve 171 to align with the positioning threaded hole group A134 or the positioning threaded hole group B135 respectively after the slide rod 107 rotates. The bolt is used to provide fixing force in the axial and radial directions, so that the airfoil sleeve 171 does not loosen or shift when the switching gear 108 is working. The setting of the airfoil sleeve 171 ensures that the switching gear 108 can reliably switch between the main gear 151 and the spare gear 161, ensuring that the stirring rod 102 can still achieve continuous drive in the event of a failure.

[0032] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the two wing plates of the airfoil sleeve 171 have through holes inside, and the through holes inside the two wing plates of the airfoil sleeve 171 are correspondingly set with the positioning threaded hole group A134 or the positioning threaded hole group B135. Traditional mixing equipment often requires the disassembly of couplings or gear components when switching power, making it impossible for the standby motor to be put into use in a short time. This structure, by setting the correspondence between the through holes and the positioning threaded hole group, allows the airfoil sleeve 171 to be directly aligned with different positioning groups after the slide rod 107 rotates. The airfoil sleeve 171 is connected and fixed to the positioning threaded hole group A134 or the positioning threaded hole group B135 by screws, so that the switching gear plate 108 can be stably positioned between different fixed points. This structure not only ensures the meshing accuracy of the switching gear plate 108, but also allows the standby motor 106 to quickly participate in the driving process after the main motor 105 fails, meeting the needs of continuous production.

[0033] like Figure 1 , Figure 3 and Figure 4As shown, the rotor shaft of the main motor 105 passes through the equipment hole A131 and is nested and fixedly installed with the main gear 151. The rotor shaft of the standby motor 106 passes through the equipment hole B133 and is nested and fixedly installed with the standby gear 161. The standby power mechanism of traditional stirring devices often lacks a direct meshing interface with the main power transmission system, resulting in the inability to quickly establish a power transmission relationship. This structure fixes the main gear 151 and the standby gear 161 to the ends of the rotor shafts of the main motor 105 and the standby motor 106, respectively, so that both the main power and the standby power have the ability to mesh with the switching gear disk 108. The main gear 151 is used to form a transmission connection with the switching gear disk 108 under normal operating conditions, while the standby gear 161 is used to form an alternative transmission relationship with the switching gear disk 108 after the main motor 105 fails. Through this setting, the main motor 105 and the standby motor 106 can share the same transmission link inside the meshing chamber 103, further improving the power switching efficiency.

[0034] like Figure 1 , Figure 3 and Figure 4 As shown, the switching gear 108 and the rod drive gear 104 are meshed, and the switching gear 108 is also meshed with the main gear 151 or the spare gear 161. In traditional stirring systems, when the main motor fails, the lack of a quick switching mechanism prevents the spare motor from providing immediate power compensation, leading to continuous production interruptions. This solution achieves rapid switching between the dual motors and the stirring rod 102 through the switching gear 108. When the airfoil sleeve 171 is fixed at the position of the positioning threaded hole group A134, the switching gear 108 and the main gear 151 mesh. The 51 meshing connection enables the main motor 105 to drive the switching gear 108 and the rod drive gear 104, thereby rotating the stirring rod 102. When the airfoil sleeve 171 is fixed in the position of the positioning threaded hole group B135, the switching gear 108 meshes with the spare gear 161, enabling the spare motor 106 to quickly take over the function of the main motor 105, allowing the stirring rod 102 to continue operating. This structure effectively solves the problems of difficult power switching and long downtime in traditional devices, and improves the reliability and practicality of continuous stirring equipment.

[0035] The working principle of this utility model is as follows:

[0036] This design adds a meshing chamber 103 and a spare motor 106 to the traditional agitator structure, as well as supporting auxiliary mechanisms such as a slide bar 107 and a switching gear 108.

[0037] When the main motor 105 is damaged, but the production operation cannot be interrupted for too long, and it is necessary to restore the operation of the stirring rod 102 in a timely manner;

[0038] At this point, use a screwdriver to remove the screws securing the airfoil sleeve 171. Then, rotate the slide rod 107 so that the through holes on both wings of the airfoil sleeve 171 coincide with the positioning threaded hole group B135. Reinstall the threaded pins to fix the airfoil sleeve 171 in the position of the positioning threaded hole group B135. Engage the switching gear 108 with the spare gear 161. Then, turn on the power switch of the spare motor 106, and the spare motor 106 can start working. The spare gear 161 drives the switching gear 108, the rod drive gear 104, and the stirring rod 102 to rotate, ensuring the continuation of production operations. The switching time is short, the switching method is quick and convenient, and it is highly practical.
