Description

Technical Field

[0001] This utility model relates to the field of sound-absorbing cotton slitting technology, and in particular to a slitting machine for processing automotive sound-absorbing cotton. Background Technology

[0002] Sound-absorbing cotton is a type of man-made inorganic fiber, made primarily from natural minerals such as quartz sand, limestone, and dolomite, combined with chemical raw materials like soda ash and borax, melted into glass-like particles. In its molten state, it is blown and spun into fine, flocculent fibers by external force. These fibers are three-dimensionally intertwined, creating numerous tiny gaps. During production, sound-absorbing cotton is mostly wound up using a winding device. To obtain a specific width of sound-absorbing cotton during the winding process, a slitting machine is typically used to cut the cotton. Existing technologies use slitting blades with fixed positions, limiting the cutting width. When the cutting width needs adjustment, the slitting blades must be replaced or individually repositioned, making the operation complex and cumbersome. Therefore, there is an urgent need for a slitting machine for processing sound-absorbing cotton that allows for easy adjustment of the cutting width. Utility Model Content

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0016] Reference Figure 1-3This utility model provides a slitting machine for processing automotive sound-absorbing cotton, including a support frame body 1, an unwinding roller 2 rotatably installed inside the support frame body 1, a winding mechanism 3 provided inside the support frame body 1, the unwinding roller 2 and the winding mechanism 3 being located on both sides of the support frame body 1, two mounting brackets 4 fixedly connected to the top of the support frame body 1, a motion shaft 5 rotatably connected between the two mounting brackets 4, a plurality of sliding blades 6 slidingly fitted on the motion shaft 5 along its axial direction, the sound-absorbing cotton on the unwinding roller 2 being connected to the winding mechanism 3 via the sliding blades 6, a slitting motor 7 for driving the motion shaft 5 and the sliding blades 6 to rotate is installed on any mounting bracket 4, and an adjustment component for adjusting the spacing of the sliding blades 6 is installed on the support frame body 1. By setting a rotating shaft between the unwinding roller 2 and the winding mechanism 3, and enabling the slitting blade 6 to rotate with the rotating shaft while moving along the axis of the rotating shaft under the action of the adjustment component, it is easy to adjust the position of the slitting blade 6, thereby adjusting the slitting width of the sound-absorbing cotton. When adjustment is required, it is only necessary to drive the motion roller 16 to rotate to complete the adjustment, which is convenient and quick to control.

[0017] The design is further optimized by fixing a base plate 8 between the two mounting brackets 4 to support the sound-absorbing cotton. The base plate 8 is located below the motion shaft 5 and has a through groove, which is correspondingly set with the slitting blade 6.

[0018] The design is further optimized by incorporating a sliding connection between the mounting frame 4 and a lifting plate 9. A motion shaft 5 is located between the two lifting plates 9 and rotates with them. A threaded rod 10 is threadedly connected to the mounting frame 4, with its bottom end rotatably connected to the lifting plate 9. The threaded rod 10 can drive the lifting plate 9 to rise, thereby driving the slitting blade 6 and the motion shaft 5 to rise, facilitating position adjustments, especially during initial use when sound-absorbing cotton needs to be passed from below the slitting blade 6 to engage with the winding mechanism 3.

[0019] Further optimization of the scheme: the adjustment component includes several retaining rings 11 rotatably connected to the motion shaft 5. The retaining rings 11 are respectively positioned on both sides of the slitting blade 6. Several connecting frames 12 are positioned on one side of the motion shaft 5 corresponding to the slitting blade 6. Two retaining rings 11 corresponding to the same slitting blade 6 are rotatably engaged with the connecting frame 12. A connecting plate 13 is fixedly connected to the side of the connecting frame 12 away from the slitting blade 6. A limiting rod 14 is fixedly connected between two mounting frames 4, passing through several connecting plates 13 and slidably engaged with them. A control component for controlling the sliding of the connecting plates 13 is installed on the support frame body 1. By controlling the sliding of the connecting plates 13 through the control component, the retaining rings 11 are moved. During the movement of the retaining rings 11, the slitting blade 6 is pushed, thereby adjusting the position of the slitting blade 6. Furthermore, the slitting blade 6 is limited by the two retaining rings 11 during rotation and will not arbitrarily deviate.

[0020] Further optimization of the scheme: The control component includes mounting plates 15 located on the side of the mounting frame 4 and fixedly connected to the main body 1 of the support frame. A motion roller 16 is rotatably connected between two mounting plates 15. A connecting rod 17 is fixedly connected to the side of the connecting plate 13 away from the connecting frame 12. Several limiting grooves 18 are opened on the periphery of the motion roller 16 corresponding to the connecting rod 17. The connecting rod 17 slides within the limiting grooves 18. The number of connecting plates 13 is odd. The limiting groove 18 in the middle position is an annular groove, and the remaining limiting grooves 18 are inclined grooves. The limiting grooves 18 on both sides of the motion roller 16 are correspondingly set. The inclination angle of the limiting grooves 18 increases with the increase of the distance from the limiting groove 18 in the middle position. A control motor 19 that drives the motion roller 16 to rotate is fixedly connected to any mounting plate 15. The control motor 19 drives the motion roller 16 to rotate, thereby driving the connecting rod 17 to move. The connecting rod 17 drives the connecting plate 13 and the connecting frame 12 to move along the axis of the motion shaft 5, thereby driving the slitting blade 6 to move, thereby adjusting the position of the slitting blade 6.

[0021] In a further optimized design, two first guide rollers 20 are rotatably connected between the two support frame bodies 1. The two first guide rollers 20 are located on both sides of the mounting frame 4, and the top surfaces of the two first guide rollers 20 are flush with the top surface of the base plate 8. Several second guide rollers 21 are rotatably connected between the two support frame bodies 1. The second guide rollers 21 are respectively set between the first guide rollers 20 and the unwinding roller 2 and between the first guide rollers 20 and the winding mechanism 3.

[0022] In a further optimized design, the central part of the motion shaft 5 is a square shaft, and rounded corners are provided at each of the four corners of the motion shaft 5. The arcs of the four rounded corners of the motion shaft 5 lie on the same circle, and several sliding blades 6 are slidably mounted on the square shaft. By making the central part of the motion shaft 5 square, the sliding blades 6 can be rotated while simultaneously sliding along the axial direction of the motion shaft 5.

[0023] Further optimization of the design: the motion roller 16 is a cylinder with a limiting groove 18, and its surface, after unfolding, becomes... Figure 3 The rectangle shown has grooves on its surface, which allow... Figure 3 The rectangle forming a cylinder is the motion roller 16, and the strip groove is the limiting groove 18. Figure 3 The middle strip groove is horizontally set, and the two side strip grooves are symmetrical and gradually inclined. The slope of the nearest strip groove in the middle strip groove is x, and the slopes of the side strip grooves are 2x, 3x and so on, thus ensuring that the spacing of the slitting blade 6 is adjusted simultaneously after the slitting blade 6 moves with the limiting groove 18.

[0024] The working process of this utility model is as follows: During use, the winding mechanism winds up the sound-absorbing cotton. When the sound-absorbing cotton passes through the mounting frame 4, it comes into contact with the rotating slitting blade 6 and is cut into a certain width. When it is necessary to adjust the slitting width, the control motor 19 is started, which drives the motion roller 16 to rotate. During the rotation of the motion roller 16, it drives the connecting rod 17 and the connecting plate 13 to move through the limiting groove 18. The connecting rod 17 located in the middle position is stationary. Taking the connecting rod 17 in the middle position as the starting point, the connecting rods 17 on both sides are rod a, rod b, and rod c in sequence. When the motion roller 16 rotates, rod a is displaced by L with the limiting groove 18, then rod B is displaced by 2L, rod c is displaced by 3L, and so on. This ensures that the distance between the connecting rods 17 is equal after the movement. This drives the slitting blade 6 to move through the connecting frame 12 and makes the distance between the slitting blades 6 equal, thereby adjusting the position of the slitting blade 6 and thus adjusting the slitting width of the sound-absorbing cotton.

They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
