Description

Technical Field

[0001] This utility model relates to the field of stirring motor technology, and in particular to a noise reduction structure for a stirring motor. Background Technology

[0002] A search revealed Chinese patent CN214674710U, which discloses a brushless motor with a noise reduction device for a mixer. The motor includes a motor housing, with a noise reduction device fitted onto the surface of the housing. This device comprises a mounting base plate, a first noise reduction frame, a second noise reduction frame, a buffer mechanism, and shock-absorbing rubber blocks. The first noise reduction frame is fixedly mounted on the upper surface of the mounting base plate, and the buffer mechanism is located on one side of the first noise reduction frame on the upper surface of the mounting base plate. This brushless motor with a noise reduction device for a mixer, belonging to the field of motors, utilizes noise-reducing cotton to adhere to the rear and front end covers of the motor housing during use. This absorbs the noise generated by the motor's vibration during operation, achieving initial noise reduction. Simultaneously, the motor housing reduces vibration through multiple buffering cycles and prevents resonance with the equipment installation area, further enhancing noise reduction performance and improving the motor's noise reduction capabilities.

[0003] The brushless motor with noise reduction device used in the stirrer in the above patent has the following shortcomings: it can reduce the noise generated by motor vibration, but the effect of dealing with the noise generated by the motor itself when it is working is not ideal. This noise will also spread to the surrounding environment, resulting in an unquiet working environment, which may affect the operator's concentration and comfort. Therefore, it is necessary to design a noise reduction structure for the stirring motor to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a noise reduction structure for a stirring motor.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A noise reduction structure for a stirring motor includes a mounting base plate. Two noise reduction frames are fixedly connected to the top of the mounting base plate. Rubber pads are fixedly connected to the inner walls of the noise reduction frames. Fixing rods pass through both sides of each noise reduction frame, and the fixing rods slidably connect to the noise reduction frames. A single motor is mounted on both rubber pads. End caps are provided at both ends of each motor. Fixing holes are provided on both sides of each end cap, and the fixing holes are adapted to the fixing rods. Positioning rods are fixedly connected to the bottom ends of both sides of each noise reduction frame. Positioning sleeves are fitted onto the positioning rods. Two positioning sleeves on the same side are fixedly connected to the same soundproof cover. Limiting mechanisms are provided on the sides of the two soundproof covers that are far apart from each other. Two limiting grooves are provided on the top of the mounting base plate. Top rods are fixedly connected to the inner walls of both ends of each soundproof cover. This structure utilizes soundproof covers and sound-absorbing cotton to treat the noise generated during motor operation, and the limiting mechanisms and limiting grooves work together effectively. The technology of restricting the position of the soundproof cover effectively reduces noise transmission when used in conjunction with the sound insulation cotton. When the limiting block is within the limiting groove, the position of the soundproof cover is restricted, allowing for proper installation. This restriction also restricts the position of the top rod, ensuring the fixing rod is stably positioned within the fixing hole, thus limiting the position of the motor. This ensures the stability of both the soundproof cover and the motor, effectively addressing the issue raised in the background technology where the noise generated by the motor itself is not ideal and can propagate into the surrounding environment, leading to an unpleasant working environment and potentially affecting the operator's concentration and comfort. The technology effectively absorbs and isolates noise, reducing its transmission to the external environment. It also facilitates the installation and disassembly of the soundproof cover and motor, making subsequent motor maintenance easier and ensuring overall maintenance efficiency.

[0007] Preferably, the inner wall of the soundproof cover is fixedly connected with soundproof cotton.

[0008] Preferably, the limiting mechanism includes a mounting box, a limiting block is slidably connected to the inner wall of the mounting box, two round rods are fixedly connected to the top of the limiting block, the round rods pass through the top of the mounting box, the round rods are slidably connected to the mounting box, the round rods are sleeved with springs, and the tops of the two round rods are fixedly connected to the same handle.

[0009] Preferably, the limiting block is adapted to the limiting groove on the mounting base plate, and the bottom end of the limiting block near the soundproof cover is inclined.

[0010] Preferably, two mounting components are fixedly connected to both sides of the mounting base plate, and the mounting components are provided with mounting holes.

[0011] Preferably, a heat dissipation mesh is provided on one side of the soundproof cover.

[0012] The beneficial effects of this utility model are as follows:

[0013] By employing soundproof covers and sound-absorbing cotton to treat the noise generated during motor operation, and by using a limiting mechanism and a limiting groove to restrict the position of the soundproof cover, the combination of the soundproof cover and sound-absorbing cotton effectively reduces noise transmission. When the limiting block is in the limiting groove, it restricts the position of the soundproof cover, allowing it to be installed properly. The restricted position of the soundproof cover also restricts the position of the top rod, ensuring the fixing rod is stably positioned within the fixing hole, thus limiting the position of the motor. This ensures the stability of both the soundproof cover and the motor, effectively solving the problem mentioned in the background technology where the noise generated by the motor itself during operation is not ideal, and this noise can also spread to the surrounding environment, leading to an unpleasant working environment and potentially affecting the operator's concentration and comfort. Therefore, this technology effectively absorbs and isolates noise, reducing its transmission to the external environment, facilitating the installation and disassembly of the soundproof cover and motor, and simplifying subsequent motor maintenance, thus ensuring overall maintenance efficiency.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-6 A noise reduction structure for a stirring motor includes a mounting base plate 1. Two noise reduction frames 2 are fixedly connected to the top of the mounting base plate 1. Rubber pads 3 are fixedly connected to the inner walls of the noise reduction frames 2. Fixing rods 4 pass through both sides of the noise reduction frames 2, and the fixing rods 4 slidably connect to the noise reduction frames 2. A single motor 5 is mounted on both rubber pads 3. End caps 501 are provided at both ends of the motor 5. Fixing holes 502 are opened on both sides of the end caps 501, and the fixing holes 502 are adapted to the fixing rods 4. Fixing rods 502 are fixedly connected to the bottom ends of both sides of the noise reduction frames 2. Positioning rod 6, with positioning sleeve 7 fitted on it. Two positioning sleeves 7 on the same side are fixedly connected to the same protective cover 8. Both protective covers 8 are provided with limit mechanisms 9 on their opposite sides. Two limit grooves 10 are opened on the top of the mounting base plate 1. Top rods 11 are fixedly connected to the inner walls of both ends of the protective cover 8. Sound insulation cotton 12 is fixedly connected to the inner wall of the protective cover 8. By setting the sound insulation cotton 12, it has good sound absorption performance, which can absorb the sound from the motor 5 and reduce the reflection and propagation of sound waves. This invention employs a soundproof enclosure and sound-absorbing cotton to treat the noise generated during motor operation, along with a limiting mechanism and a limiting groove that work together to restrict the position of the soundproof enclosure. The combination of the soundproof enclosure and sound-absorbing cotton effectively reduces noise transmission. When the limiting block is within the limiting groove, it restricts the position of the soundproof enclosure, allowing for proper installation. The restricted position of the soundproof enclosure also restricts the position of the top rod, ensuring the fixing rod is stably positioned within the fixing hole, thus limiting the position of the motor. This ensures the stability of both the soundproof enclosure and the motor, effectively addressing the problem in the background technology where the noise generated by the motor itself is not ideal and can propagate into the surrounding environment, leading to an unpleasant working environment and potentially affecting the operator's concentration and comfort. This invention effectively absorbs and isolates noise, reducing its propagation to the external environment, facilitating the installation and disassembly of the soundproof enclosure and motor, and simplifying future motor maintenance, thus ensuring overall maintenance efficiency.

[0023] In this utility model, the limiting mechanism 9 includes a mounting box 901. A limiting block 902 is slidably connected to the inner wall of the mounting box 901. Two round rods 903 are fixedly connected to the top of the limiting block 902. The round rods 903 pass through the top of the mounting box 901 and are slidably connected to the mounting box 901. A spring 904 is sleeved on the round rods 903. The tops of the two round rods 903 are fixedly connected to the same handle 905.

[0024] In this utility model, the limiting block 902 is adapted to the limiting groove 10 on the mounting base plate 1. The bottom end of the limiting block 902 near the protective cover 8 is inclined. The limiting block 902 is inserted into the limiting groove 10 to limit the soundproof cover 8, so that the two soundproof covers 8 can be installed.

[0025] In this utility model, two mounting parts 13 are fixedly connected to both sides of the mounting base plate 1. The mounting parts 13 are provided with mounting holes 14. The device is installed by passing bolts through the mounting holes 14.

[0026] In this utility model, a heat dissipation mesh 15 is provided on one side of the protective cover 8 to dissipate heat and prevent the motor 5 from overheating when it is working.

[0027] Working principle: In use, the soundproof cover 8 and soundproof cotton 12 work together. The soundproof cover 8 effectively reduces noise transmission to the surrounding environment by sealing off the noise source and physically blocking the sound transmission. The soundproof cotton 12 has good sound absorption performance and can absorb the sound from the motor 5, reducing the reflection and transmission of sound waves. The rubber pad 3 can effectively absorb the vibration generated by the motor 5 during operation, reducing the transmission of vibration to the equipment frame or the ground, thus effectively reducing noise. During assembly, the motor 5 is placed on the rubber pad 3, and the fixing holes 50 are aligned. 2. Align with the fixing rod 4 and press the soundproof cover 8 to lower it. The soundproof cover 8 will then lower the mounting box 901, causing the limiting block 902 to compress the spring 904, thus retracting the spring 904. Then, place the positioning sleeve 7 on the positioning rod 6 and push the soundproof cover 8 to move laterally. The positioning sleeve 7 moves along the positioning rod 6, and the movement of the soundproof cover 8 will move the mounting box 901. The mounting box 901 will then move the limiting block 902. When the limiting block 902 moves to the position of the limiting groove 10, the retracted spring 904... The 04 will extend, allowing the limiting block 902 to enter the limiting groove 10, thus limiting the position of the soundproof cover 8. When the soundproof cover 8 moves laterally, it will also drive the top rod 11 to move. The top rod 11 will contact the fixing rod 4 and continue to move, causing the fixing rod 4 to move until it inserts into the fixing hole 502, thus limiting the position of the motor 5 and fixing its position. When the limiting block 902 is within the limiting groove 10, the position of the soundproof cover 8 is limited, completing the assembly process. During disassembly, pull handle 905 to raise it, which will then drive the round rod 903 to rise. The round rod 903 will then drive the limit block 902 to rise, moving the limit block 902 out of the limit groove 10, thus releasing the limit and allowing the two soundproof covers 8 to move away from each other. Remove the positioning sleeve 7 from the positioning rod 6 to remove the soundproof cover 8. Pull the fixing rod 4 to remove it from the fixing hole 502, thus releasing the limit on the motor 5 and allowing the motor 5 to be disassembled, completing the disassembly work.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
