Description

Technical Field

[0001] The utility model relates to the technical field of production auxiliary noise reduction devices, in particular to a noise reduction device for factory doors. Background Art

[0002] Factory doors refer to doors used to enter and exit industrial plants, also known as factory gates. Factory doors usually have larger sizes and load-bearing capacity to meet the needs of industrial production. They are usually made of metal materials (such as steel) and have high safety and durability. Factory doors can be used to control the entry and exit of personnel and materials, and can also play a role in fire prevention, theft prevention and protection. Some factory doors are also equipped with automatic opening and closing devices to improve the convenience and efficiency of operation. Noise is often generated in industrial production, especially the operation of mechanical equipment, equipment impact and vibration, etc. will cause noise. If the factory door does not have a noise reduction device, the noise will spread to the outdoors or other areas through the door gap, door frame, etc., affecting the quietness of the surrounding environment and personnel. Noise has a certain impact on human health and work efficiency. Working in a high-noise environment for a long time may cause hearing damage, mental fatigue, distraction and other problems. By installing noise reduction devices, the spread and reflection of noise can be reduced, providing a relatively quiet working environment, improving the work comfort and production efficiency of employees; and reducing the noise pollution generated by industrial plants is an important measure to meet environmental protection requirements. By installing a noise reduction device on the factory door, the interference of factory noise on the surrounding environment can be effectively reduced, protecting the health of surrounding residents and the ecological environment. Therefore, this case hopes to propose a noise reduction device to vibrate the noise generated during industrial processing and specifically reduce the noise of the factory door. For the above problems, there may already be technical means to solve them in the existing technology, but this case wants to provide an alternative or replacement technical solution. Utility Model Content

[0003] To achieve the above objectives, the utility model is implemented through the following technical solutions: a noise reduction device for a factory door, comprising: a displacement bearing frame, a pair of noise reduction and silent door panels and a bottom coupling auxiliary frame, the displacement bearing frame is installed above the outer side of the factory door leaf, the bottom coupling auxiliary frame is installed below the outer side of the factory door leaf, a transverse displacement slide groove is opened on the displacement bearing frame, a pair of the noise reduction and silent door panels are respectively inserted into the displacement bearing frame through the transverse displacement slide groove, and a pair of the noise reduction and silent door panels are respectively connected to the factory door leaf, a groundless wheel displacement structure is installed in the displacement bearing frame, and a placement locking component is respectively installed on the displacement bearing frame and the bottom coupling auxiliary frame;

[0004] The groundless wheel displacement structure comprises: a silent plate displacement motor, a double reverse threaded threaded rod, a pair of noise reduction coupling rubber strips, a pair of side wall composite noise reduction rubber strips, a pair of plate bottom permanent magnets, a load-bearing electromagnet in the bottom frame, a pair of bottom side V-shaped covering rubber strips, an inverted V sliding key, and a pair of brushes on the strips;

[0005] The silent plate displacement motor is installed in the displacement bearing frame, the double reverse threaded rod is installed in the displacement bearing frame, and the double reverse threaded rod is connected to the silent plate displacement motor, a pair of the noise reduction and silent door panels are respectively installed on the double reverse threaded rod, a pair of the noise reduction coupling rubber strips are respectively installed on the side walls of a pair of the noise reduction and silent door panels, and a pair of the noise reduction coupling rubber strips are respectively connected to each other, a pair of the side wall composite noise reduction rubber strips are respectively installed on both sides of a pair of the noise reduction and silent door panels, a pair of the plate bottom permanent magnets are respectively installed on the bottom of a pair of the noise reduction and silent door panels, the inner bearing electromagnet of the bottom frame is installed in the bottom coupling auxiliary frame, a pair of the bottom side V-shaped covering rubber strips are respectively installed on a pair of the plate bottom permanent magnets, and a pair of the bottom side V-shaped covering rubber strips are respectively connected to a pair of bristles on the strips, the inverted V sliding key is installed on the bottom coupling auxiliary frame, and the inverted V sliding key is respectively connected to a pair of bristles on the strips.

[0006] It should be noted that, in the above, the displacement bearing frame and the bottom coupling auxiliary frame are respectively installed at the top and bottom of the factory door by installing locking components. At the same time, a pair of noise-reducing and silent door panels are tightly attached to the door surface of the factory door, and the installation position must be on the opposite side of the factory door opening side to avoid affecting the opening and closing of the factory door. If it is side-opening, it can be installed on both sides. When the factory workshop is processing, the factory door is closed first, and then the silent panel displacement motor is driven to drive the double reverse threaded rod to rotate, so that the pair of noise-reducing and silent door panels on it are close to each other until they are fitted together and closed, and the pair of noise-reducing coupling strips on it are tightly fitted together, and a pair of side wall composite noise-reducing strips fill the gap in the factory door, so that the noise on the processing side will not be transmitted to the outside world from the door gap.

The inverted V-shaped sliding key can prevent dust and processing dust from accumulating on the bottom coupling auxiliary frame, thereby blocking the closing and movement of the noise-reducing and silent door panels. At the same time, the bristles on a pair of strips in a pair of bottom V-shaped covering rubber strips will rub and clean the inverted V-shaped sliding keys that are in contact, making the noise-reducing and silent door panels move more smoothly and further reducing the risk of jamming. Even if the processing environment is harsh, it will not affect the normal operation of the device. The bottom V-shaped covering rubber strip can further prevent the bottom gap from transmitting sound noise outward.

The honeycomb sound-absorbing layer arranged in the noise-reducing and silent door panel can prevent excessive noise from being transmitted to the outside through the noise-reducing and silent door panel, thereby further enhancing the noise reduction function of the entire device.

[0011] Preferably, a maintenance door is provided on the bottom coupling auxiliary frame;

[0012] Preferably, a honeycomb sound-absorbing layer is provided in the noise-reducing and silent door panel;

[0013] Preferably, a wear-resistant protective layer is provided on the inverted V-shaped sliding key. Beneficial Effects

[0014] The utility model provides a noise reduction device for factory doors. Compared with the prior art, the noise reduction device for factory doors has the following beneficial effects: the device uses a groundless wheel displacement structure to replace the normal door panel bottom slide by magnetic force, thereby perfectly solving the problem that the general pulley and slide groove combination in the industry is often prone to dust accumulation, resulting in slippage and difficulty in maintenance, and further makes the ease of use and maintenance of the device much better than the general noise reduction door panel equipment without affecting the noise reduction function.
