Description
Technical Field
[0001] This utility model relates to the field of anti-adhesion vibration technology, and more specifically, to an anti-adhesion vibration device. Background Technology
[0002] With the widespread application of rotary drum equipment, such as dryers, mixers, and rotary kilns, in industries such as chemical, building materials, and food processing, materials often adhere to the inner wall of the drum during drying, mixing, and calcination processes due to their high temperature, high humidity, and stickiness, forming a bonding layer. This not only leads to a decrease in the equipment's heat transfer efficiency and effective volume but can also cause localized overheating, resulting in drum deformation and even requiring frequent shutdowns for cleaning. This severely impacts production efficiency and equipment lifespan, while increasing energy consumption and maintenance costs.
[0003] Traditional anti-adhesion technologies, such as mechanical scraping devices, remove scale by using fixed scrapers, which are prone to wear due to friction and have poor adaptability to complex-shaped rollers. Externally mounted vibrators result in uneven vibration force transmission and insufficient local rapping effect. Chemical coating treatments are costly, have limited coating life, and require regular maintenance. In addition, traditional solutions generally suffer from incomplete rapping coverage, inflexible parameter adjustment, and cumbersome maintenance processes, making it difficult to meet the demands of modern industry for efficient, intelligent, and reliable equipment.
[0004] Therefore, it is necessary to design an anti-adhesion rapping device to solve the problems of uneven rapping, easy wear and tear of equipment, high maintenance costs, and poor adaptability to working conditions in the existing technology. The device can achieve full circumferential rapping coverage of the inner wall of the drum, uniform distribution of rapping force, quick replacement of parts and intelligent adjustment of parameters, improve the anti-adhesion efficiency and service life of the equipment, reduce the difficulty of operation and maintenance and energy consumption, and adapt to the needs of diversified production processes. Utility Model Content

A movable frame is provided on the fixed end of the electric telescopic rod, and a locking block that matches the slot is provided on the movable frame.
[0012] Furthermore, it also includes a sun gear, which meshes with planet gears.
[0013] Furthermore, the drive shaft of the sun gear is connected to an external motor.

[0019] The fixed gear ring of this application meshes with the planetary assembly, replacing the complex multi-stage transmission, reducing the size of the equipment and improving the transmission efficiency.

Detailed Implementation
[0027] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.
[0028] In the description of this application, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this application.
[0029] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.
[0030] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0031] See Figure 1-2 As shown, this embodiment provides an anti-adhesion rapping device, including: a roller 1 and a transmission mechanism.
[0032] Specifically, the inner wall surface of the roller 1 is provided with a number of vibrating blocks 11 and bolt holes 12 along the circumferential direction.
[0033] Specifically, the transmission mechanism is provided with a fixed gear ring 23, which is fixedly connected to the inner side of the roller 1. The fixed gear ring 23 meshes with a planetary assembly, and the planetary assembly is provided with a rapping mechanism. The rapping hammer 31 of the rapping mechanism is correspondingly arranged with the rapping block 11.
[0034] Understandably, by striking the rapping block 11, the rapping block 11 transmits the striking force to the roller 1, thus avoiding damage caused by prolonged direct striking of the roller 1.
[0035] Specifically, the vibrating block 11 is bolted to the roller 1 through the bolt hole 12.
[0036] Understandably, bolted connections facilitate the installation and removal of the vibratory block 11. This allows for quick operation during equipment maintenance, repairs, or replacement of these components, reducing maintenance difficulty and time costs, and ensuring the normal operation of the equipment and subsequent upgrades.
[0037] It can be seen that the combination of roller 1, transmission mechanism and rapping mechanism constructs the basic structural framework of the anti-adhesion rapping device, laying the foundation for realizing the anti-adhesion function of rapping. The rapping block 11 on roller 1 provides the rapping hammer 31 with the target for rapping, while the transmission mechanism can transmit power to make the rapping mechanism work.
[0038] See Figure 1-2 As shown, in some embodiments of this application, the planetary assembly includes a plurality of planetary gears 21, a planet carrier 2, and a connecting rod 22.
[0039] Specifically, planetary gear 21 is hinged to planet carrier 2 via connecting rod 22, and planetary gear 21 meshes with fixed gear ring 23.
[0040] It is understandable that by using the meshing transmission between the planetary gear 21 and the fixed gear ring 23, a more complex and stable motion transmission can be achieved. Compared with a simple transmission method, it can achieve multi-directional and multi-angle motion distribution in a limited space, providing a suitable motion trajectory and power transmission for the rapping mechanism. The planetary carrier 2 follows the planetary gear 21 to perform cyclic reciprocating motion, thereby driving the rapping mechanism to achieve 360° striking.
[0041] See Figure 1-3 As shown, in some embodiments of this application, the vibrating mechanism further includes a vibrating rod 3.
[0042] Specifically, the vibrating rod 3 and the connecting rod 22 are detachably connected.
[0043] Understandably, the vibrating rod 3 and the connecting rod 22 are detachably connected, which facilitates quick disassembly and installation when the vibrating rod 3 is damaged or needs to be replaced with a vibrating rod of a different specification, thereby reducing maintenance costs and improving the maintainability and flexibility of the device.
[0044] See Figure 1-3 As shown, in some embodiments of this application, the end of the connecting rod 22 connected to the vibrating mechanism is provided with a slot 221 that matches the vibrating rod 3. The side wall of the slot 221 is provided with a plurality of slots 222. The side wall of the vibrating rod 3 is provided with a groove 32. An electric telescopic rod 33 is provided in the groove 32. The telescopic end of the electric telescopic rod 33 is fixedly connected to the groove 32. A movable frame 34 is provided on the fixed end of the electric telescopic rod 33. A locking block 35 that matches the slot 222 is provided on the movable frame 34.
[0045] It is understandable that the extension and retraction of the electric telescopic rod 33 can control the engagement and disengagement of the locking block 35 and the locking slot 222.
[0046] As can be seen, the above methods enable convenient and secure connection and disassembly between the vibrating rod 3 and the connecting rod 22. The electric control method makes operation more automated and precise; when the vibrating rod 3 needs to be replaced, it can be done quickly without complicated tools, improving the ease of use and work efficiency of the equipment.
[0047] See Figure 1 As shown, in some embodiments of this application, a sun gear 5 is also included.
[0048] Specifically, the sun wheel 5 meshes with the planet wheel 21.
[0049] Understandably, the inclusion of the sun gear 5 makes the planetary transmission system more complete and stable. As a power input component, the sun gear 5 can better coordinate the movement of the planetary gears 21, precisely control the speed and transmission ratio of the planetary components, thereby making the movement of the rapping mechanism more regular and stable, and improving the anti-adhesion rapping effect.
[0050] See Figure 1 As shown, in some embodiments of this application, the drive shaft 51 of the sun gear 5 is connected to an external motor.
[0051] Understandably, the external motor provides the power source for the entire transmission system. By connecting the external motor to the sun gear 5 and the drive shaft 51, the device can be easily powered. The operating frequency and intensity of the rapping device can be precisely adjusted by controlling parameters such as the motor's speed and direction, according to actual needs, thereby achieving effective control of the anti-adhesion rapping operation.
[0052] See Figure 1 As shown, in some embodiments of this application, the planetary carrier 2 and the drive shaft 51 are rotatably connected by bearings.
[0053] Understandably, the rotating bearing connection reduces the frictional resistance between the planetary carrier 2 and the drive shaft 51, allowing the planetary carrier 2 to rotate more smoothly during transmission, improving the transmission efficiency of the device, extending the service life of the components, and ensuring the stability of the entire transmission system.
[0054] See Figure 1-3 As shown, in some embodiments of this application, the end of the vibrating hammer 31 near the vibrating block 11 is the striking surface, which is arc-shaped, and a connecting block 312 is provided on the other side of the vibrating block 11.
[0055] See Figure 3 As shown, in some embodiments of this application, the vibrating rod 3 has a placement groove 36 at one end near the vibrating hammer 31.
[0056] Specifically, a spring 311 is provided in the placement groove 36, and a connecting block 312 is placed in the placement groove 36. One end of the spring 311 is fixed to the bottom of the placement groove 36, and the other end is connected to the connecting block 312.
[0057] Understandably, the presence of spring 311 can buffer the impact of the rapping hammer 31 on the rapping block 11, reducing the damage to the rapping rod 3 and other components of the rapping mechanism caused by the instantaneous impact of the rapping. At the same time, it gives the rapping hammer 31 a certain elastic restoring ability, making the rapping process more stable and continuous, and improving the reliability and service life of the rapping device.
[0058] As can be seen, the circumferentially arranged rapping blocks 11 on the inner wall of the roller 1 of this application can achieve 360° rapping without dead angles, eliminate blind spots for material adhesion, improve anti-adhesion efficiency, and solve the problem of local adhesion residue caused by uneven rapping in the prior art.
[0059] The fixed gear ring 23 of this application meshes with the planetary assembly, replacing the complex multi-stage transmission, reducing the size of the equipment and improving the transmission efficiency.
[0060] The rapping hammer 31 of this application corresponds one-to-one with the circumferential rapping block 11. The impact force is evenly distributed on the inner wall of the drum 1, avoiding local stress concentration, extending the service life of the drum 1, and reducing maintenance costs and downtime caused by equipment damage.
[0061] This application integrates planetary transmission with a circumferential rapping layout to construct an efficient, uniform, adaptable, and easy-to-maintain anti-adhesion rapping system. It solves the pain points of traditional technologies such as rapping blind spots, structural redundancy, uneven force distribution, single working conditions, and complex maintenance, and also significantly improves the performance and market competitiveness of the equipment in the field of material handling.
[0062] It will be understood by those skilled in the art that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
