Description

Technical Field

[0001] This utility model belongs to the field of sound insulation cotton slitting technology, and in particular relates to a multi-blade slitting device for conveying sound insulation cotton. Background Technology

[0002] Automotive sound insulation cotton is a lightweight, porous material installed inside vehicles (such as door panels, floors, wheel arches, hoods, and trunks) primarily to absorb and block noise, improving ride comfort. It is typically made of polyester fibers, glass wool, foam, or composite acoustic materials. By filling cavities in the vehicle body and covering metal sheeting, it effectively attenuates the propagation and reflection of engine noise, tire noise, wind noise, and external environmental noise within the vehicle. Simultaneously, its material also possesses thermal insulation properties, reducing heat transfer and further optimizing the cabin environment. Ultimately, through physical blocking and sound wave energy conversion, it creates a quieter and smoother moving space for passengers.

[0003] After the automotive sound insulation cotton is produced, it needs to be cut into the required width according to the customer's needs by a slitting device. The slitting device is installed at the end of the automated sound insulation cotton production equipment and is located in front of the winding mechanism. After the sound insulation cotton is cut by the slitting device, it is then wound up by the winding mechanism.

[0004] During production, sound insulation cotton is cut into different widths and equal parts according to different customer needs. When it is necessary to increase or decrease the number of cut parts, traditional equipment needs to install or remove a cutter before the cutting work is carried out. The removed cutter requires extra storage space, and the installation and removal work is also cumbersome and complicated, which is not conducive to the quick switching of cut parts.

[0005] To address the aforementioned issues, this application proposes a multi-blade cutting device for conveying sound-insulating cotton. Utility Model Content

[0006] The purpose of this invention is to provide a multi-blade cutting device for conveying sound insulation cotton, which solves the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model relates to a multi-blade cutting device for conveying sound insulation cotton, comprising a frame, the frame including a fixed frame and an adjusting seat fixed to the side of the fixed frame, a support seat fixed to the top of the fixed frame, an adjusting slider with horizontal sliding in the adjusting seat, a spline shaft with elastic lifting and lowering via a spring in the adjusting slider, a blade mounted on the lower end of the spline shaft, a cylinder fixed on the support seat, the output end of the cylinder facing downward and fixed to a follower seat, a follower block with horizontal sliding at the lower end of the follower seat, a linkage block fixed to the side of the follower block, a through hole coaxial with the spline shaft through the linkage block, at least part of the upper end of the spline shaft being inserted into the through hole, and a long bolt in the linkage block capable of blocking the top of the spline shaft in the through hole.

[0009] Furthermore, the adjusting slider has a spline hole that slides with the spline shaft, and the spring is sleeved on the outside of the spline shaft with its two ends fixed between the bottom of the adjusting slider and the backing plate, respectively.

[0010] Furthermore, a clamping screw that passes through the adjusting seat is fixed to the side of the adjusting slider, and a clamping sleeve is threadedly connected to the clamping screw to screw-tighten the adjusting seat.

[0011] Furthermore, a guide rod is fixed at the bottom of the follower seat, and a guide hole is opened on the follower block to slide outside the guide rod, and at least two sets of the guide rod and guide hole are provided.

[0012] Furthermore, guide grooves are provided on both sides of the follower seat, and guide strips are fixedly provided at both ends of the inner side of the support seat to slide in cooperation with the guide grooves.

[0013] Furthermore, the side of the linkage block is provided with threaded holes that are perpendicular to and interconnected with the through holes, and the long bolt is threadedly connected to the threaded holes.

[0014] Furthermore, the cylinder has at least two symmetrical cylinders.

[0015] This utility model has the following beneficial effects:

[0016] This invention switches whether the cylinder drives the blade by intercepting the long bolt at the top of the spline shaft. When the long bolt is intercepted at the top of the spline shaft, the cylinder moves down to drive the blade to move down for cutting. When the long bolt is disengaged, the cylinder cannot move the blade down, thus achieving a quick switch between whether the blade is working and improving the flexibility and variability of actual use.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0026] 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.

[0027] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0028] Please see Figure 1 - Figure 5 As shown, this utility model is a multi-blade cutting device for conveying sound insulation cotton, including a frame 1. The frame 1 includes a fixed frame 11 and an adjusting seat 12 fixed to the side of the fixed frame 11. A support seat 13 is fixed to the top of the fixed frame 11. An adjusting slider 2 that slides horizontally is provided in the adjusting seat 12. A spline shaft 3 that can be elastically lifted and lowered is provided in the adjusting slider 2 through a spring 4. A blade 32 is installed at the lower end of the spline shaft 3. A cylinder 6 is fixed on the support seat 13. The output end of the cylinder 6 faces downward and is fixed with a follower seat 7. A follower block 8 that slides horizontally is provided at the lower end of the follower seat 7. A linkage block 82 is fixed to the side of the follower block 8. A through hole 821 coaxial with the spline shaft 3 is provided through the linkage block 82. At least part of the upper end of the spline shaft 3 is inserted into the through hole 821. A long bolt 9 that can block the top of the spline shaft 3 in the through hole 821 is provided in the linkage block 82.

[0029] To prevent the blade 32 from rotating on the adjusting slider 2 and affecting the cutting path, the adjusting slider 2 is provided with a spline hole 21 that slides with the spline shaft 3; furthermore, the spring 4 is sleeved on the outside of the spline shaft 3 and its two ends are respectively fixed between the bottom of the adjusting slider 2 and the backing plate 31. In this embodiment, the spring 4 is used for automatic reset of the blade 32.

[0030] Specifically, a clamping screw 22 passing through the adjusting seat 12 is fixed on the side of the adjusting slider 2, and a clamping screw sleeve 5 is threadedly connected to the clamping screw 22 to screw and clamp the adjusting seat 12.

[0031] More specifically, when the clamping screw 5 is turned clockwise, it is pressed against the adjusting seat 12 by the screw of the clamping screw 22, thus positioning the adjusting slider 2 on the adjusting seat 12; when the clamping screw 5 is turned counterclockwise, it is released from the clamping of the adjusting seat 12, and at this time the adjusting slider 2 can be slid on the adjusting seat 12 to adjust the cutting position.

[0032] To ensure the stability of the follower block 8 at the bottom of the follower seat 7, a guide rod 71 is fixed at the bottom of the sliding follower seat 7. A guide hole 81 is opened on the follower block 8 to slide outside the guide rod 71, and at least two sets of guide rods 71 ​​and guide holes 81 are provided. In this embodiment, by setting two sets of guide rods 71 ​​and guide holes 81, the stable sliding of the follower block 8 at the lower end of the follower seat 7 is improved.

[0033] Furthermore, guide grooves 72 are provided on both sides of the follower seat 7, and guide bars 131 are fixed at both ends of the inner side of the support seat 13 and slide in cooperation with the guide grooves 72. Through the cooperation of the guide bars 131 and the guide grooves 72, the stability of the follower seat 7 in lifting and lowering within the support seat 13 is improved, thereby ensuring the stable pushing of multiple blades 32.

[0034] Specifically, the side of the linkage block 82 is provided with threaded holes 822 that are perpendicular to and interconnected with the through holes 821, and the long bolt 9 is threadedly connected to the threaded holes 822.

[0035] More specifically, when the long bolt 9 is turned clockwise, it passes through the threaded hole 822 and the front end of the long bolt 9 enters the through hole 821 and forms a block at the top of the spline shaft 3. When the long bolt 9 is turned counterclockwise, the long bolt 9 disengages from the through hole 821, and at this time there is no block at the top of the spline shaft 3.

[0036] Specifically, there are at least two symmetrical cylinders 6. In this embodiment, the two cylinders 6 are used to ensure stable and uniform power transmission, stably push the follower seat 7, and thus enable the pushed blade 32 to move synchronously.

[0037] It is understandable that this utility model controls whether the switching cylinder can drive the blade to perform slitting work by using the interception state of the long bolt at the top of the spline shaft, thereby achieving rapid switching of the blade's working state and improving the flexibility and variability of use.

[0038] One specific application of this embodiment is as follows: Figure 3 All the blades 32 shown are in the reset state under the action of spring 4. At this time, the top of all spline shafts 3 are located in the through hole 821 and are lower than the long bolt 9.

[0039] Blade 32 position adjustment: Loosen the screws of the clamping sleeve 5 and the clamping screw 22, and the clamping sleeve 5 is disengaged from the adjusting seat 12. The sliding of the clamping sleeve 5 can drive the adjusting slider 2 to move horizontally in the adjusting seat 12. The adjusting slider 2 drives the linkage block 82 and the follower block 8 to move synchronously through the part of the spline shaft 3 inserted into the through hole 821. The guide hole 81 follows and slides outside the guide rod 71 until it is adjusted to the desired position. Tighten the clamping sleeve 5 and press it against the side of the adjusting seat 12 to position the adjusting slider 2.

[0040] Switching between cutting and splitting blade 32: When the blade 32 at the corresponding position needs to work, the long bolt 9 is turned and passed through the through hole 821. At this time, the long bolt 9 forms a block at the top of the spline shaft 3. When the cylinder 6 moves down in this state, the follower seat 7 and follower block 8 also move down. The long bolt 9 in the linkage block 82 presses down on the spline shaft 3 and pushes it down. The blade 32 moves down to the splitting position, and the spring 4 is stretched. When a certain blade 32 does not need to work, the long bolt 9 is turned outward so that the long bolt 9 is no longer blocking the spline shaft 3. At this time, after the cylinder 6 moves down, the linkage block 82 moves downward outside the spline shaft 3 through the through hole 821, but it will not drive the spline shaft 3 and the blade 32 to move down. Therefore, the blade 32 at this position does not perform splitting work.
