Description

Technical Field

[0001] The utility model relates to the technical field of sound insulation panels, and more particularly to a sound insulation panel for tobacco machinery and equipment. Background Art

[0002] The primary function of sound insulation panels is to reduce the noise generated by operating machinery and minimize sound transmission. This is particularly important in workplaces such as tobacco factories where a low-noise environment is crucial, as long-term exposure to high noise levels can damage workers’ hearing and overall health.

[0003] A search of existing public documents revealed that patent publication number CN220848118U discloses a sound insulation and noise reduction panel with a sound insulation and noise reduction structure. This panel works by abutting the top of a circular ring against two internal limit blocks, squeezing the beveled surface, and causing the two limit blocks to slide within corresponding grooves, moving the circular ring above the two limit blocks. Then, under the elastic force of two springs, the two limit blocks return to their original positions and secure the circular ring, thereby completing the docking of the two panels. This allows for rapid docking and splicing of the panels, improving docking efficiency. However, this panel has the following drawbacks.

[0004] When soundproofing tobacco machinery and equipment, sound insulation and noise reduction panels need to be placed in the gaps of the tobacco machinery and equipment shell. However, the gaps at the joints of the sound insulation panels are difficult to seal and soundproof, resulting in the tobacco machinery and equipment being difficult to seal and soundproof during use. The sound insulation effect is poor, so sound insulation and silencer panels are needed for tobacco machinery and equipment. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the utility model provides a sound insulation and silencer plate for tobacco machinery equipment.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a sound insulation and silencer panel for tobacco machinery and equipment, comprising a stainless steel plate, a foam layer and a reinforcement frame, wherein the foam layer is bonded to one side of the stainless steel plate, and the reinforcement frame is fixedly connected to the outer wall of the foam layer, and an edge sealing sound insulation mechanism is provided on one side of the reinforcement frame; the edge sealing sound insulation mechanism comprises sound insulation cotton fixedly arranged on one side of the reinforcement frame, and a sponge frame is bonded and fixed to one side of the sound insulation cotton, an outer wall of the sponge frame is fixedly connected with an adhesive strip, and a groove is provided on the outer wall of the adhesive strip and near its four corner lines; a support plate is fixedly installed on the inner wall of the sponge frame.

[0007] Preferably, the foam layer has a rectangular vertical cross-section, the stainless steel plate has a larger vertical cross-sectional area than the foam layer, and the foam layer has a plurality of sound-absorbing holes formed therein, each of which has a circular vertical cross-section and a smooth inner wall.

[0008] A reinforcement strip is fixedly connected to one side of the support plate, and a support column is fixedly connected between the support plate and the foam layer. A vacuum groove is opened inside the stainless steel plate, and the inner wall of the vacuum groove is a smooth surface.

[0009] In this technology, a stainless steel plate is inserted into the slot of the tobacco machinery's outer shell and squeezed into the slot by the outer wall of the reinforcement frame. The multiple slots on the adhesive strip can spread outward and move. The outer wall of the adhesive strip is bonded to the outer edge of the tobacco machinery. The sound insulation cotton seals the gaps around the outer edge of the tobacco machinery, and the noise is absorbed by the multiple sound-absorbing holes in the foam layer, making the foam layer more stable in sound insulation. At the same time, the foam layer further insulates the sound. The sound insulation cotton, sponge frame, and adhesive strip provide edge sealing and sound insulation, which has a better edge sealing sound insulation effect.

[0010] Preferably, an outward-expanding sound insulation component is installed on the other side of the stainless steel plate; the outward-expanding sound insulation component includes a sound insulation cotton board, a rubber frame, a bonding cotton strip, a bonding film, multiple slots and a support frame; the sound insulation cotton board is fixedly connected to the other side of the stainless steel plate, and the rubber frame is fixed to one side of the sound insulation cotton board, and the bonding cotton strip is bonded to the outer wall of the rubber frame; the inner wall of the rubber frame is fixedly connected to the bonding film, and the outer wall of the bonding cotton strip is provided with slots near its four corner lines, and one end of the reinforcement strip is fixedly installed with a support frame, and the rubber frame can be made of rubber material, and the multiple slots are arranged in a rectangular distribution.

[0011] In this technology, sealing glue is applied to the outer wall of the bonding cotton strip, the bonding film is pushed outward, the rubber frame squeezes the bonding cotton strip to spread outward, and the groove on the bonding cotton strip is moved outward to achieve outward diffusion. The bonding cotton strip can be sealed and bonded to the outer edge of the groove body of the tobacco machinery equipment shell. The bonding cotton strip, rubber frame and bonding film realize multiple sealing and sound insulation.

[0024] In this embodiment, as shown in the attached Figure 2-3 As shown, a plurality of sound-absorbing holes 8 are provided inside the foam layer 2, and the vertical cross-section of the sound-absorbing holes 8 is circular, and the inner wall of the sound-absorbing holes 8 is a smooth surface, so that noise can be absorbed through the plurality of sound-absorbing holes 8 on the foam layer 2, and the sound absorption effect is better. A reinforcement strip 10 is fixedly connected to one side of the support plate 9, and a support column 11 is fixedly connected between the support plate 9 and the foam layer 2, so that the support plate 9 can be supported by the reinforcement strip 10.
