[0042] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0043] Please refer to Figures 1-4 , the present invention provides the following technical solutions: A cotton feeding device for producing automotive interior sound insulation cotton, including a belt conveyor 1, a cutting box 2 fixed on the belt conveyor 1, and a cutting mechanism 3 installed on the cutting box 2. There is a feeding port 21 at the bottom of the cutting box 2 for the sound insulation cotton to pass through. The cutting mechanism 3 includes: an N-shaped movable frame 31, a cutting knife 32, an electric push rod 33, an extension plate 34, and a pressing plate 35.

[0044] Furthermore, as shown in Figure 1 and Figure 2 , in this embodiment, the N-shaped movable frame 31 is located inside the cutting box 2 and has a degree of freedom of movement in the vertical direction. The cutting knife 32 is fixed inside the N-shaped movable frame 31. The electric push rod 33 is fixed at the top of the cutting box 2, and the piston rod of the electric push rod 33 passes through the cutting box 2 and is fixedly connected to the N-shaped movable frame 31. Two extension plates 34 are symmetrically fixed on the N-shaped movable frame 31. The pressing plate 35 is elastically connected directly below the extension plate 34. After adopting the above solution, during use, the sound insulation cotton is conveyed to the belt conveyor 1 by the pre-feed equipment, and the belt conveyor 1 transfers the sound insulation cotton. When the sound insulation cotton moves to the cutting position, the electric push rod 33 is started, and the piston rod of the electric push rod 33 pushes the N-shaped movable frame 31 downward. Since the pressing plate 35 is elastically connected directly below the extension plate 34, the pressing plate 35 will first contact the sound insulation cotton and press the sound insulation cotton tightly as the N-shaped movable frame 31 moves downward, ensuring the stability of the sound insulation cotton. Finally, the sound insulation cotton is cut by the cutting knife 32, and the cutting accuracy is high.

[0045] Optionally, as shown in Figure 1 and Figure 2As shown, in this embodiment, it further includes: a telescopic rod 36 and a telescopic spring 37. A plurality of telescopic rods 36 are evenly distributed and fixed between the extension plate 34 and the pressing plate 35. The telescopic spring 37 is sleeved on the telescopic rod 36 and is located between the extension plate 34 and the pressing plate 35. After adopting the above solution, during use, when the pressing plate 35 contacts the sound insulation cotton and the n-shaped movable frame 31 continues to move downward, the telescopic rod 36 and the telescopic spring 37 will contract to gently press the sound insulation cotton downward.

[0046] It should be noted that the initial height of the pressing plate 35 is lower than the height of the cutting knife 32, ensuring that the pressing plate 35 contacts the sound insulation cotton first, and the telescopic rod 36 and the telescopic spring 37 will contract during cutting, ensuring the reliability of cutting and at the same time ensuring the stability of the sound insulation cotton. The telescopic rod 36 and the telescopic spring 37 can also ensure that the initial height of the pressing plate 35 is lower than the height of the cutting knife 32. Among them, the telescopic rod 36 is a telescopic structure composed of two hollow cylindrical members sleeved together.

[0047] Preferably, as shown by Figure 1 and Figure 2 in this embodiment, it further includes: a rubber gasket 351. The rubber gasket 351 is adhesively fixed to the bottom surface of the pressing plate 35. The rubber gasket 351 has flexibility, and the rubber gasket 351 is used to press the sound insulation cotton downward, with higher safety.

[0048] Optionally, as shown by Figure 1 、 Figure 2 and Figure 4 in this embodiment, it further includes: a locking bolt 38 and a locking nut 39. A plurality of locking bolts 38 are evenly distributed, and the locking bolts 38 penetrate through the n-shaped movable frame 31 and the cutting knife 32. The locking nut 39 is installed on the protruding end of the locking bolt 38 by means of screw thread engagement. Therefore, in this utility model, the cutting knife 32 is fixedly installed by using the locking bolt 38 and the locking nut 39, which is convenient and stable for installation, and at the same time, it is also easy to disassemble and maintain the cutting knife 32.

[0049] Preferably, as shown by Figure 1 and Figure 2 in this embodiment, it further includes: a guiding column 311. Two guiding columns 311 are symmetrically fixed to the top surface of the n-shaped movable frame 31 and penetrate through the cutting box 2. After adopting the above solution, the two guiding columns 311 are used to guide the n-shaped movable frame 31, improving the stability of the n-shaped movable frame 31.

[0050] Preferably, as shown by Figure 1As shown in the figure, in this embodiment, a material guiding mechanism 5 is further included. The material guiding mechanism 5 is fixed to the feeding end of the belt conveyor 1, and the material guiding mechanism 5 includes: a fixing frame 51, a material guiding roller 52, and a driving motor 53. The two fixing frames 51 are symmetrically fixed on the belt conveyor 1. The material guiding roller 52 is rotatably installed between the two fixing frames 51. The driving motor 53 is fixed on the fixing frame 51 and is used to drive the material guiding roller 52 to rotate. After adopting the above solution, during operation, the driving motor 53 is started to drive the material guiding roller 52 to rotate, so that the sound insulation cotton bypasses the material guiding roller 52 (whether it bypasses from above or below the material guiding roller 52 needs to be determined according to the height of the previous feeding equipment. For example, if the height of the previous feeding equipment is higher than that of the material guiding roller 52, it is preferably to make the sound insulation cotton bypass from below the material guiding roller 52), and the sound insulation cotton is assisted to be pushed.

[0051] Preferably, by Figure 1 As shown in the figure, in this embodiment, a double-door 4 and a transparent observation window 41 are further included. One end of the cutting box 2 has an opening. The double-door 4 is hinged in the opening. The transparent observation window 41 is embedded and fixed in the double-door 4. When processing, closing the double-door 4 can provide safety protection, and the cutting state of the sound insulation cotton can be observed through the transparent observation window 41. Opening the double-door 4 facilitates the maintenance of the cutting mechanism 3.

[0052] Preferably, by Figure 1 As shown in the figure, in this embodiment, a reserved interface 22 is further included.

[0056] Working principle and usage process of the present utility model: For the cotton feeding device of the present utility model, during use, the sound insulation cotton is conveyed to the belt conveyor 1 by the front-end feeding equipment, and the belt conveyor 1 transfers the sound insulation cotton. When the sound insulation cotton moves to the cutting position, the electric push rod 33 is started, and the piston rod of the electric push rod 33 pushes the n-shaped movable frame 31 to move downward. The pressing plate 35 will first contact the sound insulation cotton and press the sound insulation cotton tightly as the n-shaped movable frame 31 moves downward, ensuring the stability of the sound insulation cotton. Finally, the sound insulation cotton is cut by the cutter 32, and the cutting accuracy is high;

[0057] After the cutting is completed, the electric push rod 33 is started to pull up the n-shaped movable frame 31, and the belt conveyor 1 is continued to be started to transfer the sound insulation cotton. Repeatedly executing the above process can complete the cutting and cotton feeding of the sound insulation cotton;
