Description

Technical Field

[0001] The utility model relates to production equipment for automobile sound insulation pads, in particular to a composite device for producing automobile sound insulation pads. Background Art

[0002] The production process of automobile sound insulation pads generally requires processes such as drying and cutting after the steam-injected molding is completed. Considering that the composition of the sound insulation pads includes some fiber materials such as cotton, filament, and floc, the heat generated during the traditional cutting process will affect these components. Therefore, water jet cutting is generally considered. However, the waste water generated during the water jet cutting process will be centrally collected in the water tank below. Because the flow rate of the water jet is extremely fast, it will cause a great impact on the water in the water tank. Therefore, splashing water will be generated, and this water will splash back onto the sound insulation pad again, causing the dried sound insulation pad to become wet again and affecting the quality.

A jet buffer structure 6 is arranged below the cutting device 5. The jet buffer structure 6 includes a water tank 61, and the water tank 61 is fixedly installed on the bracket 1. By arranging the workbench 2, drying is completed during the process of moving the sound insulation pad material by the feeding roller 3 and the discharging roller 4. At the same time, the arranged cutting device can cut the sound insulation pad to complete the composite processing of the sound insulation pad.

[0029] In this embodiment, discontinuous holes 21 are arranged on the workbench 2, and the discontinuous holes 21 are located directly below the water jet nozzle 51, facilitating the flow of water to the water tank 61 below.

[0030] In this embodiment, the cutting device 5 further includes an adjustment bracket 52, a threaded rod 53, a guide rod 54, and a mounting plate 55. The adjustment bracket 52 is fixedly installed on the bracket 1. The threaded rod 53 and the guide rod 54 are arranged side by side and parallel on the adjustment bracket 52. An electric motor 56 is provided at the end of the threaded rod 53. Gaskets 56 are provided at both ends of the guide rod 54 and the guide rod 54 is fixedly installed on the adjustment bracket 52 through the gaskets 56. Both ends of the mounting plate 55 are respectively installed on the threaded rod 53 and the guide rod 54. The water jet nozzle 51 is fixedly installed on the mounting plate 55. The threaded rod 53 can drive the mounting plate 55 to move back and forth to help the water jet nozzle 51 move and cut the sound insulation pad.

[0031] In this embodiment, the adjustment bracket 52 includes a fixing frame 521, a guide frame 522, a cross beam 523, and a cylinder 524. The fixing frame 521 is symmetrically installed on the bracket 1. The guide frame 522 is symmetrically arranged on both sides of the fixing frame 521 and is provided with guide grooves. Both ends of the cross beam 523 are slidably connected to the guide frame 522 through sliders. The middle position of the cross beam 523 is connected to the output shaft of the cylinder 524. The cylinder 524 is installed on the fixing frame 521 through a cylinder bracket. The cylinder 524 can drive the cross beam 523 and drive the threaded rod 53 and the guide rod 54 installed on the cross beam 523 to move up and down. At the same time, the guide frame 522 can provide guidance.

[0032] In this embodiment, the jet buffer structure 6 further includes a flow collector 62, a water inlet cover 63, and a partition 64. The bottom of the flow collector 62 is fixedly installed on the partition 64. The water inlet cover 63 is fixedly installed on the water tank 61 and is coaxially installed with the flow collector 62 in the vertical direction. There is a drain hole between the bottom of the water inlet cover 63 and the flow collector 62. Water inlet pipes 631 are provided on both sides of the lower end of the water inlet cover 63. The water inlet pipes 631 are connected to an external water pump. The partition 64 is fixedly installed in the water tank 1 and divides the water tank 1 into upper and lower parts. Water will flow into the water inlet cover 63 from bottom to top through the water inlet pipes 631, and these waters will finally be discharged from the bottom of the water tank 61 through the flow collector 62.

[0033] In this embodiment, the cross section of the flow collector 62 is a trumpet shape with a spherical shell at the upper end and a hollow plate at the lower end. The top of the water inlet cover 63 is higher than the flow collector 62 and a guiding plate 632 is provided at the upper end of the side wall. The guiding plate 632 is higher than the flow collector 62 and bends towards the inside of the flow collector 62. When the water flowing in from below the water inlet cover 63 rises to the guiding plate 632, it flows into the spherical shell from the guiding plate 632 and finally flows into the flow collector 62, forming a situation where the water level is high at the position of the guiding plate 632 and low at the middle position of the flow collector 62.

[0034] In this embodiment, a suction pipe 65 installed on the bottom plate of the water tank 61 is provided below the partition 64, and a drain pipe 66 is also provided on the water tank 1. The suction pipe 65 is used to suck out the water flow in the collecting cover 62 to keep the water flow at the mouth of the spherical shell on the top of the collecting cover 62 stable.

[0035] Working principle: First, start the feed roller 3 to transport the sound insulation pad material to the workbench 2. At this time, the sound insulation pad can be dried by the heating wire on the workbench 2. At the same time, when the front end of the sound insulation pad enters the discharge roller 4, the feed roller 3 and the discharge roller 4 stop, and the sound insulation pad is cut by the set water jet nozzle 51. During cutting, the water inlet cover 63 located below will flow water from bottom to top through the water inlet pipe 631. When the inflowing water rises to the guide plate 632, it flows from the guide plate 632 to the spherical The water flows into the shell and finally flows into the collecting cover 62, forming a situation where the water level at the position of the guide plate 632 is high and the water level at the middle position of the collecting cover 62 is low. At this time, since the water flow sprayed by the water jet nozzle 51 above is located at the center of the collecting cover 62, the incoming water flow will be eliminated by the collecting cover 62 and the splashing water will be blocked by the higher water surfaces on both sides to prevent the splashing water from wetting the sound insulation pad. After the cutting is completed, the discharge roller 4 will send the sound insulation pad out of the workbench 2 until the next cutting.

[0036] Based on the above, the utility model is provided with a workbench with a heating wire, which can complete the drying of the sound insulation pad during transportation; the collecting hood is provided to collect the water flow sprayed by the water jet nozzle, and eliminate the impact force of the water flow through the hollow plate at the lower end of the collecting hood that is deep enough; the water inlet hood is provided to allow surging water to flow into the collecting hood from both sides of the collecting hood, which can destroy the tension of the water surface through continuous flow, and at the same time form a water surface with high sides and low middle. When the jet of the water jet hits the low water surface in the middle, the splashing water will be blocked by the high water bodies on both sides to prevent splashing onto the sound insulation pad.

[0037] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the utility model concept and technical solution of the utility model, or the utility model concept and technical solution are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
