Description

Technical Field

[0001] The utility model relates to the technical field of sound-absorbing cotton production equipment, and specifically, to a sound-absorbing cotton composite production equipment. Background Art

[0002] Sound-absorbing cotton is an artificial composite material with an attractive effect. Usually, a sound-absorbing cotton compounding machine is used to compound the embossed aluminum foil layer, the polyester fiber sound-absorbing cotton layer and the adhesive layer with release paper into one layer. The aluminum foil layer is the surface layer, the polyester fiber sound-absorbing cotton layer is the middle layer, and the adhesive layer with release paper is the bottom layer.

[0003] The function of the aluminum foil embossing machine is to emboss patterns on the originally smooth aluminum foil, and use the embossed aluminum foil on sound-absorbing cotton and sound-insulating cotton products to improve their sound insulation and noise reduction effects. Most of the existing aluminum foil embossing machines use two symmetrically arranged screw rods to adjust the distance between the upper and lower pressing rollers, thereby adjusting the embossing force of the aluminum foil embossing machine. However, the adjustment of the two screw rods cannot be completely synchronized, which may cause the two ends of the upper pressing roller to be not on the same horizontal line, thereby affecting the quality of the finished aluminum foil.

[0004] During the process of producing sound-absorbing cotton, the sound-absorbing cotton compounding machine needs to simultaneously transport the embossed aluminum foil layer, the polyester fiber sound-absorbing cotton layer and the adhesive layer with release paper to the inside of the compounding machine for processing. In order to prevent the adhesive layer with release paper from adhering to the aluminum foil layer and the polyester fiber sound-absorbing cotton layer when transporting the materials for producing sound-absorbing cotton to the inside of the compounding machine body, the embossed aluminum foil layer, the polyester fiber sound-absorbing cotton layer and the adhesive layer with release paper are usually transported separately to the inside of the machine. Therefore, it is necessary to install a device to guide the aluminum foil layer, the polyester fiber sound-absorbing cotton layer and the adhesive layer, resulting in a relatively large size of the compounding machine for producing sound-absorbing cotton, which requires a large floor space, and therefore requires a relatively large workshop area, increasing the investment cost of the factory.

[0005] Therefore, improvements are made to address the above problems. Utility Model Content

The second gear 3-5 is meshed with the first gear 3-3. Transmission wheels 3-6 are arranged at one end of the center roller 3-1 and one end of the side roller 3-2.

[0033] In this embodiment, in order to achieve the effect of synchronous conveying of the three materials of the aluminum foil layer, the polyester fiber sound-absorbing cotton layer and the adhesive layer, a synchronous conveying component 3 is designed. A center roller 3-1 and two side rollers 3-2 are arranged inside the first base frame 1. The center roller 3-1 is driven to rotate by a motor as a driving force. When rotating, it drives one of the side rollers 3-2 to rotate through the transmission wheel 3-6. The side rollers 3-2 are driven by the first gear 3-3, the second gear 3-5 and the transmission shaft 3-4 to achieve opposite rotation effects, so as to achieve the effect of synchronous rotation of the center roller 3-1 and the side rollers 3-2, ensuring that there will be no deviation when the materials are conveyed simultaneously.

[0034] Specifically, in order to achieve effective clamping and bonding of the conveyed materials, a clamping and bonding component 4 is designed, which can clamp and bond the three materials being conveyed at a controllable interval.

[0035] Furthermore, the clamping and fitting component 4 includes a pair of side grooves 4-1, and the side grooves 4-1 are opened on the inner surface of the first base frame 1. A driving screw 4-2 is rotatably connected in the side grooves 4-1. A second motor 4-3 is provided on the outer surface of the first base frame 1. The output end of the second motor 4-3 is connected to the driving screw 4-2. A pair of moving blocks 4-4 are connected to the outside of the driving screw 4-2 through threaded cooperation. A connecting rod 4-5 is provided on the inner surface of the first base frame 1. A clamping roller 4-6 is rotatably connected to the side end face of the moving block 4-4, and the other end of the clamping roller 4-6 is slidably sleeved and connected to the outside of the connecting rod 4-5.

[0036] In this embodiment, a driving screw 4-2 with a double-start thread structure is provided on the side surface of the first base frame 1, and the thread directions at both ends are respectively positive spiral and reverse spiral. The two moving blocks 4-4 can be synchronously driven to shorten or expand the distance through rotation, and the distance between the two clamping rollers 4-6 can be adjusted according to the clamping thickness. The other end of the clamping roller 4-6 is slidably connected to a connecting frame, which serves as a support.

[0038] In this embodiment, the clamped sound-absorbing cotton is transported by a conveying roller 5-3, and a heating tube 5-4 and a heat-conducting pressing layer 5-5 are arranged in the second base frame 2, so that the heat-conducting pressing layer 5-5 can maintain a certain temperature, and the circular holes 5-6 on the surface can increase the temperature transfer effect, thereby heating the sound-absorbing cotton during the transportation process. The top is connected to a pressing plate 5-8 through a second cylinder 5-7, and the pressing plate 5-8 presses the sound-absorbing cotton against the surface of the heat-conducting pressing layer 5-5, thereby completing the processing stably and effectively.

[0039] Furthermore, the transmission wheels 3-6 are connected by belt transmission, and the first gear 3-3 and the second gear 3-5 are both bevel gears.

[0040] In this embodiment, the two transmission wheels 3-6 can be kept synchronous and rotate in the same direction through the belt transmission, and then through the bevel gear, the two side rollers 3-2 can achieve the effect of opposite rotation.

[0041] Furthermore, both right angles at the bottom ends of the pressed plates 5-8 are arc-shaped transition structures.

[0042] In this embodiment, the arc-shaped transition structure allows the material to slide more smoothly against the surface of the pressing plates 5-8, and the conveying movement is more fluent.

[0043] When processing is required, the aluminum foil layer, polyester fiber sound-absorbing cotton layer and adhesive layer are respectively installed on the outside of the central roller 3-1 and the two side rollers 3-2, and then all are pulled out between the clamping rollers 4-6. Manual bonding is first performed and then the second motor 4-3 is started. The two moving blocks 4-4 are driven by the driving screw 4-2 to adjust the spacing of the clamping rollers 4-6 to clamp the material, and then the material is started and conveyed. The material passes through the conveying roller 5-3 and enters the surface of the heat-conducting pressing layer 5-5. Then, according to the start of the second telescopic cylinder 5-1, the pressing plate 5-8 is adjusted until it is pressed on the surface of the material, and the heating tube 5-4 is heated for heating. The heating and forming are maintained during the conveying process to complete the processing.
