Sound absorbing cotton composite device

Abstract

This utility model discloses a sound-absorbing cotton composite device, including a base, a frame mounted on the base, and a pressing device mounted on the frame. A mounting plate is fixed inside the base, and a support is slidably connected to the mounting plate. A partition plate is located inside the support, a driving mechanism is located below the partition plate, and a limiting mechanism is located above the partition plate. In this device, the limiting mechanism can limit the position of the sound-absorbing cotton. The limiting mechanism uses an electric push rod to push a sliding rod to slide within a guide groove, adjusting the position of the limiting block to ensure effective limiting of sound-absorbing cotton raw materials of different specifications. An air pump inside the limiting block draws air through an air nozzle, using air pressure to assist in fixing the sound-absorbing cotton raw material, preventing the material from shifting during processing and affecting the composite quality. Simultaneously, the air pressure reduces damage to the surface of the sound-absorbing cotton raw material, making it suitable for softer sound-absorbing cotton materials.

Description

Technical Field

[0001] This utility model relates to the field of sound-absorbing cotton processing technology, specifically to a sound-absorbing cotton composite equipment. Background Technology

[0002] Sound-absorbing cotton is a type of artificial composite material widely used to reduce sound propagation.

[0003] When producing sound-absorbing cotton, it is necessary to bond and press the cotton together to fix the pattern and cut it into the required shape. In existing equipment, there is no fixed structure around the sound-absorbing cotton, which makes it easy for the sound-absorbing cotton to shift during pressing under the influence of external forces, thus affecting the pressing effect of the sound-absorbing cotton. Utility Model Content

[0004] The main objective of this invention is to provide a sound-absorbing cotton composite device to solve the aforementioned technical problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sound-absorbing cotton composite device, including a base, a frame on the base, a pressing device on the frame; an installation plate fixedly installed inside the base, a support slidably connected to the installation plate, a partition plate inside the support, a driving mechanism below the partition plate, and a limiting mechanism above the partition plate.

[0006] Based on the above scheme and as a preferred embodiment of the above scheme: the driving mechanism includes a sector gear, which is disposed on the bottom of the inner cavity of the support, and a drive motor is disposed below the sector gear. The drive motor is fixed on the inner bottom wall of the base; racks are provided on both sides of the bottom of the inner cavity of the support, and the sector gear meshes with the racks for transmission.

[0007] Based on the above scheme and as a preferred embodiment of the above scheme: the bottom outer wall of the support is slidably connected to the mounting plate.

[0008] Based on the above scheme and as a preferred embodiment of the above scheme: the limiting mechanism includes a guide groove opened on the top of the support and an electric actuator fixed on the partition plate. The output end of the electric actuator is provided with a slide rod, and a limiting block is provided on the slide rod. An air pump is provided inside the limiting block. A limiting groove is opened on the outside of the limiting block, and an air nozzle is provided inside the limiting groove. The output end of the air pump is connected to the air nozzle. The slide rod is slidably connected to the guide groove.

[0009] Based on the above scheme and as a preferred embodiment of the above scheme: the pressing device includes a cylinder mounted on a frame, the output end of the cylinder is provided with a fixing plate, and the fixing plate is provided with a pressing mold.

[0010] The beneficial effects of this utility model are as follows: By setting a limiting mechanism, the sound-absorbing cotton can be limited. The limiting mechanism pushes the slide rod to slide in the guide groove through the electric push rod, and the position of the limiting block can be adjusted to ensure effective limiting of sound-absorbing cotton raw materials of different specifications. The air pump in the limiting block draws air through the air nozzle, which can use air pressure to assist in fixing the sound-absorbing cotton raw material, avoiding the material from affecting the composite quality due to position displacement during processing. At the same time, the air pressure also reduces the damage to the surface of the sound-absorbing cotton raw material, which is suitable for softer sound-absorbing cotton materials.

[0015] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. However, the specific implementation methods and embodiments described below are for illustrative purposes only and are not intended to limit the present invention.

[0016] See attached diagram. Figures 1 to 4 The sound-absorbing cotton composite device in this embodiment includes a base 1, a frame 2 on the base 1, and a pressing device on the frame 2; an installation plate 3 is fixedly installed inside the base 1, a support 4 is slidably connected to the installation plate 3, a partition plate 40 is installed inside the support 4, a driving mechanism is provided below the partition plate 40, and a limiting mechanism is provided above the partition plate 40.

[0017] In the above scheme, the driving mechanism includes a sector gear 50, which is disposed on the bottom of the inner cavity of the support 4. A drive motor 5 is disposed below the sector gear 50 and is fixed on the inner bottom wall of the base 1. A rack 51 is provided on both sides of the bottom of the inner cavity of the support 4, and the sector gear 50 meshes with the rack 51 for transmission.

[0018] In the above scheme, the bottom outer wall of the support 4 is slidably connected to the mounting plate 3.

[0019] In the above scheme, the limiting mechanism includes a guide groove 41 opened on the top of the support 4 and an electric push rod 400 fixed on the partition plate 40. The output end of the electric push rod 400 is provided with a slide rod 6, a limiting block 7 is provided on the slide rod 6, an air pump is provided in the limiting block 7, a limiting groove 70 is opened on the outside of the limiting block 7, an air nozzle 71 is provided in the limiting groove 70, and the output end of the air pump is connected to the air nozzle 71; the slide rod 6 is slidably connected to the guide groove 41.

[0020] In the above scheme, the pressing device includes a cylinder 20 mounted on the frame 2, a fixed plate 21 at the output end of the cylinder 20, and a pressing mold 22 mounted on the fixed plate 21.

[0021] In this equipment, the drive mechanism adopts a transmission method of sector gear 50 and rack 51 meshing. Under the action of drive motor 5, it can drive support 4 to reciprocate and slide horizontally on mounting plate 3; this facilitates continuous processing of sound-absorbing cotton and improves processing efficiency. Specifically, after the sound-absorbing cotton is placed on the top of support 4 and fixed, drive motor 5 is started and sector gear 50 is driven to rotate. Sector gear 50 meshes with rack 51 on one side, causing support 4 to slide to one side under pressing device for processing. At the same time, drive motor 5 stops rotating until processing is completed and material is unloaded. After unloading, drive motor 5 is started again. At this time, sector gear 50 meshes with rack 51 on the other side, causing support 4 to return to its original position, and feeding can continue.

[0022] Furthermore, the limiting mechanism pushes the slide bar 6 to slide within the guide groove 41 via the electric push rod 400, which can adjust the position of the limiting block 7 to ensure effective limiting of sound-absorbing cotton raw materials of different specifications; the air pump inside the limiting block 7 draws air through the air nozzle 71, which can use air pressure to assist in fixing the sound-absorbing cotton raw materials, avoiding the material from affecting the composite quality due to positional displacement during processing; at the same time, the air pressure also reduces damage to the surface of the sound-absorbing cotton raw materials, making it suitable for softer sound-absorbing cotton materials;

[0023] In the pressing device, the cylinder 20 drives the fixed plate 21 and the pressing mold 22 to move up and down, and the limiting mechanism ensures that there will be no misalignment or displacement during the pressing process.

[0024] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
