Description

Technical Field

[0001] The utility model relates to the technical field of vibration plates, in particular to a sound-insulating and noise-reducing vibration plate. Background Art

[0002] The vibration plate is an auxiliary feeding equipment for automatic assembly or automatic processing machinery. It can arrange various products in an orderly manner, and cooperate with automatic assembly equipment to assemble various parts of the product into a complete product, or cooperate with automatic processing machinery to complete the processing of workpieces. The vibration plate is widely used in various industries such as electronics, hardware, plastics, medicine, and food.

[0003] Since the working principle of the vibration plate is to transport materials by mechanical vibration, it will generate a lot of noise during the working process. At present, the main means to solve the noise in the industry are as follows:

[0004] 1. Apply PU glue on the surface of the vibration plate. Since PU glue is soft, it can reduce vibration noise. However, after long-term use, PU glue will gradually wear out, fall off, and pollute the material;

[0005] 2. Although the sound insulation cover is loaded on the outside of the vibration plate, it can achieve a certain sound insulation effect, but it is not convenient to add materials. The sound insulation cover must be removed every time before adding materials;

[0006] 3. Use a more precise frequency modulator to reduce the amplitude of the vibration plate, reduce the material jump, and also achieve the purpose of noise reduction. However, the purchase and modification cost of the precision frequency modulator is high, and not every company is willing to bear this cost.

[0007] In summary, the current means of solving the vibration plate noise all have certain drawbacks. In view of this, the present application proposes a sound-insulating and noise-reducing vibration plate in order to solve the above-mentioned problem. Utility Model Content

[0010] Furthermore, a sound insulation baffle is provided on both sides of the bottom of the feeding port, and the two sides of the sound insulation baffle are rotatably connected to the two sides of the bottom of the sound insulation cover through torsion springs.

[0011] Furthermore, a limiting ring is provided at each of the upper and lower ends of the feeding port.

[0012] Furthermore, a lower sound insulation cover is provided on the outer side of the bottom shell.

[0013] Furthermore, a rubber pad is provided at the bottom of the bottom shell.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The vibration plate of the utility model can effectively reduce the noise of the vibration plate when it is working by the arrangement of the sound insulation cover and the sound insulation cover, and the vibration plate can be conveniently fed with materials at any time by the arrangement of the feed port and the sound insulation baffle; the above-mentioned sound insulation method has a simple structure and low cost, which is conducive to enterprises to upgrade the existing vibration plates to reduce the overall noise of the production workshop.

[0017] Figure 2 It is a schematic diagram of the overall cross-sectional structure of the utility model. DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] like Figure 1-2 As shown, the sound insulation and noise reduction vibration plate of this embodiment includes a bottom shell 1, a pulse electromagnet 2, a spring sheet 3, a plate body 4, an upper sound insulation cover 5, a lower sound insulation cover 6 and a sound insulation cover 7. The pulse electromagnet 2 is arranged in the bottom shell 1, and multiple groups of spring sheets 3 are obliquely arranged on both sides of the pulse electromagnet 2. The plate body 4 is arranged above the bottom shell 1, and the upper and lower ends of the spring sheet 3 are respectively connected to the bottom shell 1 and the plate body 4.

[0020] The pulse electromagnet 2 can make the plate 4 vibrate in the vertical direction, and the inclined spring sheet 3 drives the plate 4 to do torsional vibration around its vertical axis. The material in the plate 4 rises along the spiral track due to this vibration, thereby realizing automatic and orderly loading of materials.

[0021] The upper soundproof cover 5 is arranged on the outside of the disc body 4, the lower soundproof cover 6 is arranged on the outside of the bottom shell 1, and the soundproof cover 7 is arranged on the top of the upper soundproof cover 5; the upper soundproof cover 5, the lower soundproof cover 6 and the soundproof cover 7 can be made of sponge, rubber, soundproof cotton and other materials, which can absorb the vibration generated when the vibration disc is working, thereby reducing the noise. The soundproof cover 7 is connected to the upper soundproof cover 5 in a threaded manner, which is convenient for disassembly during maintenance.

[0022] A rubber pad 8 is also provided at the bottom of the bottom shell 1 to further reduce the vibration and noise of the vibration plate.

[0023] A feeding port 9 is movably provided on the soundproof cover 7 , and a circle of limiting rings 10 are respectively provided at the upper and lower ends of the feeding port 9 for limiting the feeding port 9 on the soundproof cover 7 so that it can only slide up and down along the opening on the soundproof cover 7 .

[0024] A soundproof baffle 11 is provided on both sides of the bottom of the feeding port 9, and the two sides of the soundproof baffle 11 are rotatably connected to the two sides of the bottom of the soundproof cover 7 through the torsion spring 12. When feeding, the feeding port 9 is pressed downward, and the feeding port 9 pushes the soundproof baffles 11 on both sides open, so that the material can enter the plate body 4 along the feeding port 9; after the feeding is completed, the feeding port 9 is released, and the soundproof baffles 11 on both sides are driven to reset under the action of the torsion spring 12, closing the feeding channel, and at the same time isolating the noise during the working process of the vibration plate to prevent the noise from leaking out.

[0025] In summary, the sound insulation method adopted by the utility model has a simple structure and low cost, which is beneficial for enterprises to upgrade and transform existing vibration plates to reduce the overall noise of the production workshop.

[0026] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
