[0032] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application belongs; the terms used herein are for the purpose of describing specific embodiments only and are not intended to limit this application. The terms "including" and "having" and any variations thereof in the specification and claims of this application and the accompanying drawings are intended to cover non-exclusive inclusions.

[0034] The sound-absorbing cotton used in cars usually needs to be covered with cloth on the upper and lower sides to ensure that it will not fall apart when installed on the car. Therefore, when cutting this type of sound-absorbing cotton, it is necessary to seal the edges while cutting. Generally, the die-cutting and hot-melt sealing processes are used to prevent the cloth and the sound-absorbing cotton from separating and misaligning after cutting. A small part of the cut sound-absorbing cotton will stick to the main body. At this time, manual separation is required, and the cut sound-absorbing cotton must be manually torn out one by one from the cutting edge on the main body, which increases the workload and is not conducive to improving work efficiency.

[0035] Based on this, the problem in the related technology that a small part of the cut sound-absorbing cotton will stick to the main body can be improved. At this time, manual separation is required, and the cut sound-absorbing cotton is manually torn out one by one from the cutting edge on the main body, which increases the workload and is not conducive to improving work efficiency.

[0036] See also Figure 1-Figure 7 A sound-absorbing cotton board cutting device includes a mounting bracket 1 and a cutting device 4. A conveyor belt 2 is installed on the top of the mounting bracket 1, and a driving device 3 is installed on the bottom of the mounting bracket 1. The conveyor belt 2 is driven by the driving device 3. The cutting device 4 is arranged at the outer end of the conveyor belt 2, and a winding assembly 5 is provided at the end of the conveyor belt 2 away from the cutting device 4. A guide assembly 6 is provided at one end of the mounting bracket 1, and an air jet assembly 7 and a material blocking assembly 8 are respectively provided on the inner side of the guide assembly 6. The material blocking assembly 8 includes a mounting shaft 81, and a scraper 82 is fixedly installed on the outer end of the mounting shaft 81. The air jet assembly 7 includes a mounting frame 71, and a plurality of nozzles 72 are fixedly installed on the outer end of the mounting frame 71.

[0037] A conveyor belt 2 is installed on the top of the mounting bracket 1 in this solution. The conveyor belt 2 is mainly driven by a driving device 3 installed at the bottom of the mounting bracket 1. The driving device 3 is mainly composed of a servo motor, a transmission gear and a reducer. The power provided by the driving device 3 can make the conveyor belt 2 move. A cutting device 4 and a winding component 5 are respectively provided at both ends of the conveyor belt 2. The cutting device 4 is mainly used for cutting the sound-absorbing cotton. The cutting device 4 is mainly composed of a cylinder driving device, a die-cutting tool and a hot-melt edge sealing device. The die-cutting tool needs to be customized to make it consistent with the size of the sound-absorbing cotton to be cut, and the hot-melt edge sealing device is mainly used to seal the cut sound-absorbing cotton. The die-cutting tool can achieve the edge sealing effect through the heat energy of the hot-melt edge sealing device and its own pressure during the cutting process, ensuring that the edge sealing process can effectively prevent burrs or warping. Since the sound-absorbing cotton is usually rolled, a feeding device is provided at the rear end of the cutting device 4, so that the sound-absorbing cotton cut by the cutting device 4 can be conveyed to the other end through the conveyor belt 2. At this time, the sound-absorbing cotton is guided to the bottom of the guide roller 1 62, and then after it passes under the guide roller 1 62, it is guided upward to the two guide rollers 2 63 and wound on the winding roller shaft 52. At this time, the sound-absorbing cotton can be automatically moved by the winding of the winding component 5. Since only a small part of the cut sound-absorbing cotton is adhered to the main body, the nozzle 72 blows out high-pressure gas to blow the cut small pieces of sound-absorbing cotton downward to separate them. At this time, if the nozzle 72 does not blow down and does not pass through the obstruction of the scraper 82, it can be scraped off, so that only manual auxiliary operation is required to automatically remove the cut sound-absorbing cotton. It is worth mentioning that a material receiving container needs to be provided under the guide component 6 when in use.

[0038] Optionally, in some embodiments, see Figure 3-Figure 5 The guide assembly 6 includes a fixing frame 61, which is fixedly mounted on the outer end of the mounting bracket 1, and a guide roller 62 is rotatably connected to the inner side of the fixing frame 61.

[0039] Two second guide rollers 63 are rotatably connected to the inner side of the fixing frame 61 . Two limit blocks 64 are fixedly connected to the inner side of the fixing frame 61 . The limit blocks 64 are located below the second guide roller 63 .

[0040] The fixing frame 61 mentioned above is fixed to the outer end of the mounting bracket 1, and a guide roller 1 62 and two guide rollers 2 63 are rotatably installed on the inner side of the fixing frame 61. The edge of the sound-absorbing cotton after being hot-melt sealed will be harder. Therefore, through the cooperation of guide roller 1 62 and guide roller 2 63, the sound-absorbing cotton with less adhesion can be squeezed and peeled off by guide roller 1 62 first, and then peeled off for the second and third time through the jet assembly 7 and the material blocking assembly 8, thereby improving the success rate of separation.

[0041] Optionally, in some embodiments, see FIG. Figure 3-Figure 5The material blocking assembly 8 also includes a threaded rod 84 , an outer shell 85 is fixedly installed on the outer end of the mounting shaft 81 , the scraper 82 is located inside the outer shell 85 , and a threaded block 83 adapted to the threaded rod 84 is fixedly connected to the bottom end of the outer shell 85 .

[0042] A sliding groove adapted to the threaded block 83 is provided at the bottom end of the fixing frame 61. The threaded block 83 passes through the sliding groove. The threaded rod 84 is rotatably installed at the bottom end of the fixing frame 61, and the threaded rod 84 is threadedly connected to the threaded block 83. The two limit blocks 64 are respectively in contact with the two ends of the outer shell 85.

[0043] The outer shell 85 in this scheme is fixed to the outer end of the mounting shaft 81, and a scraper 82 is fixed to the outer end of the mounting shaft 81. The scraper 82 is also located on the inner side of the outer shell 85. The limit block 64 fixed on the fixing frame 61 is adapted to the outer shell 85. The distance between the two limit blocks 64 is the same as the length of the outer shell 85. At the same time, a slide groove is provided at the bottom of the fixing frame 61 between the two limit blocks 64. The slide groove is mainly used to allow the threaded block 83 at the bottom of the outer shell 85 to pass through, and the threaded rod 84 is rotatably connected to the bottom of the fixing frame 61. The threaded rod 84 is threadedly connected to the threaded block 83. By rotating the threaded rod 84, the distance between the scraper 82 and the guide roller 62 can be adjusted, so that it can be adjusted according to the cutting of sound-absorbing cotton of different specifications. The edge of the sound-absorbing cotton after hot-melt sealing will be harder and the edge will be easy to curl up. At this time, the sound-absorbing cotton that was not blown off by the jet assembly 7 can be blocked and peeled off by the obstruction of the scraper 82.

[0044] Optionally, in some embodiments, see Figure 5 The jet assembly 7 also includes a connecting pipe 73, and multiple nozzles 72 are connected through the connecting pipe 73. The mounting frame 71 is fixedly mounted on the top of the fixing frame 61. One end of the connecting pipe 73 is connected to an external pipe 74, and one end of the external pipe 74 is externally connected to the air supply system.

[0045] The jet assembly 7 in this scheme is mounted above the material blocking assembly 8 and the guide assembly 6, and multiple nozzles 72 are installed through the mounting frame 71, and the air outlet of the nozzle 72 is set downward. The mounting frame 71 is fixed on the top of the fixing frame 61, and multiple nozzles 72 are connected through a connecting pipe 73. An external pipe 74 for air supply is connected to the connecting pipe 73. The external pipe 74 is connected to an external air supply system. The air supply system is mainly composed of an air pump and a switch valve. Through the connection of the external pipe 74 and the connecting pipe 73, the nozzle 72 can blow out high-pressure gas downward, blowing the cut small pieces of sound-absorbing cotton downward to separate them from the main body.

[0046] Optionally, in some embodiments, see Figure 7The winding assembly 5 includes a winding frame 51 and a belt 55. The winding roller shaft 52 is rotatably connected to the inner side of the winding frame 51. A driving motor 53 is fixedly installed on the inner side of the winding frame 51. A pulley 54 is fixedly installed at one end of the winding roller shaft 52 and the output end of the driving motor 53. The two pulleys 54 are connected by a belt 55.

[0047] The winding roller 52 is rotatably installed on the inner side of the winding frame 51 in this scheme. One end of the winding roller 52 passes through the side wall of the winding frame 51 and is installed with a pulley 54. At the same time, the driving motor 53 fixed to the bottom of the winding frame 51 also passes through its side wall. The output end is installed with a pulley 54, and the two pulleys 54 can be connected by a belt 55. When the driving motor 53 is working, the winding roller 52 can be rotated. The waste of the cut sound-absorbing cotton is wound on the winding roller 52, which can not only pull the sound-absorbing cotton and provide pulling force for it to pass through the guide component 6, the jet component 7 and the material blocking component 8, but also collect the waste on the winding roller 52, so that it can be conveniently collected and processed, which can reduce the labor intensity of the staff and improve their work efficiency.

[0048] Working principle: When using the device, the sound-absorbing cotton needs to be guided to the cutting device 4 first, and cut by the cutting device 4. The sound-absorbing cotton cut by the cutting device 4 is conveyed to the other end through the conveyor belt 2. At this time, the sound-absorbing cotton is guided to the bottom of the guide roller 1 62, and then after it passes under the guide roller 1 62, it is guided upward to the two guide rollers 2 63, and finally it is wound on the winding roller shaft 52. At this time, the winding of the winding assembly 5 can make the sound-absorbing cotton move automatically. The edge of the sound-absorbing cotton after the hot-melt edge sealing will be harder. Therefore, when passing through the guide roller 1 62, the sound-absorbing cotton with less adhesion can be squeezed and peeled off by the guide roller 1 62 first, and then the nozzle 72 blows out high-pressure gas to blow the cut small pieces of sound-absorbing cotton downward to separate them. At this time, if the nozzle 72 does not blow down and does not pass through the obstruction of the scraper 82, it can be scraped off, so that only manual auxiliary operation is required to automatically remove the cut sound-absorbing cotton.
