Description

Technical Field

[0001] This utility model relates to the field of cutting technology, specifically a cutting device for processing honeycomb automotive sound insulation cotton. Background Technology

[0002] In the automotive manufacturing industry, honeycomb sound insulation cotton, with its unique honeycomb structure, can effectively absorb and block noise, significantly improving driving comfort and becoming a key material for noise reduction in automotive interiors. However, in the process of processing honeycomb automotive sound insulation cotton, it needs to be divided, so a cutting device is required to achieve the division. However, the existing cutting devices for processing automotive sound insulation cotton still have certain defects in use.

[0003] For example, the cutting device for producing automotive sound insulation cotton proposed in application number CN202421142969.8 belongs to the field of sound insulation cotton cutting technology. It includes a mounting frame, and an adjustment mechanism is provided at the upper end of the mounting frame. The adjustment mechanism includes a motor and two adjustment discs. The motor drives the two adjustment discs to rotate synchronously. Each of the two adjustment discs is provided with a rod, and the two rods are rotatably connected to the slider. A cutting mechanism is provided on the lifting plate. In actual use, this cutting device for producing automotive sound insulation cotton achieves the cutting of sound insulation cotton by driving the cutting blade to rise and fall. However, it is not convenient to adjust the cutting angle of the sound insulation cotton during cutting. At the same time, the sound insulation cotton is prone to move during the cutting process of the cutting blade rising and falling, which reduces the cutting effect.

[0004] Therefore, we propose a cutting device for processing honeycomb automotive sound insulation cotton to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to provide a cutting device for processing honeycomb automotive sound insulation cotton, so as to solve the problems mentioned in the background art, such as the inconvenience of adjusting the cutting angle of the sound insulation cotton and the movement of the sound insulation cotton affecting the cutting effect.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cutting device for processing honeycomb automotive sound insulation cotton, including a support base, a fixed plate fixedly installed in the middle of the support base, a rotating seat rotatably passing through the inside of the fixed plate, a cutting table fixedly connected to the top of the rotating seat, and grooves formed at equal angles on the surface of the cutting table;

[0007] An angle positioning mechanism is connected between the rotating base and the fixed plate to achieve angle positioning;

[0008] Cylinders are fixedly installed at both ends of the support base. A limit frame is connected to the top of the cylinder. The limit frame is slidably connected to both ends of the support base. A lifting seat is fixedly connected to the top of the limit frame.

[0009] A cutting mechanism, which is installed at the top rear end of the lifting platform, is used to perform cutting operations;

[0010] The extrusion mechanism is installed on the top inner side of the lifting seat for extrusion positioning.

[0011] Preferably, the angle positioning mechanism includes a rotating disk fixedly installed on the top outer ring of the rotating seat. The rotating disk has positioning grooves formed at equal angles inside. The bottom end of the rotating seat is connected to a connecting bearing. The bottom end of the connecting bearing is connected to a connecting block. The bottom end of the connecting block is fixedly installed with a limit rod. The bottom of the limit rod is fixedly installed with a baffle. A lifting plate is slidably arranged on the surface of the limit rod. A first spring is sleeved on the outer ring of the limit rod between the lifting plate and the baffle. Positioning rods are fixedly installed at both ends of the lifting plate. A pedal is fixedly connected to the bottom end of the positioning rod.

[0012] Preferably, the lifting plate forms a telescopic structure with the first spring and the baffle, and the positioning rod is movably engaged with the positioning groove.

[0013] With the above-described structure, pressing the pedal causes the lifting plate to compress the first spring and disengage the positioning rod from the positioning slot. At this point, the cutting table and rotating seat can be rotated. After adjusting to the appropriate angle, the pedal is released, and under the elastic force of the first spring, the positioning rod re-engages into the positioning slot, achieving precise angle positioning of the cutting table and facilitating cutting operations at different angles on honeycomb automotive sound insulation cotton.

[0014] Preferably, the cutting mechanism includes an electric slide fixedly installed on the rear side of the top of the lifting seat. A connecting frame is fixedly connected to the bottom surface of the sliding part of the electric slide. A drive motor is fixedly installed at the bottom end of the connecting frame. A cutting blade is fixedly connected to the shaft end of the drive motor.

[0015] With the above-mentioned structural design, the electric slide can drive the connecting frame, drive motor and cutting blade to move in a straight line. The drive motor drives the cutting blade to rotate at high speed, so as to achieve stable and precise cutting of honeycomb automotive sound insulation cotton placed on the cutting table. The electric slide can accurately control the cutting stroke and position, improving cutting accuracy and efficiency.

[0016] Preferably, the extrusion mechanism includes a limiting plate fixedly installed inside the lifting seat, a lifting rod slidingly passing through the inside of the limiting plate, a stop block fixedly installed at the top of the lifting rod, a pressure plate fixedly connected to the bottom of the lifting rod, a second spring sleeved on the outer ring of the lifting rod between the pressure plate and the limiting plate, and a through groove opened inside the pressure plate.

[0017] Preferably, the lifting rods are evenly distributed inside the limiting plate, the pressure plate and the limiting plate are connected by a second spring, and the position of the through groove corresponds to the position of the cutting blade.

[0018] With the above-mentioned structure, the cylinder pushes the lifting seat down, and the pressure plate first contacts the sound insulation cotton. Under the action of the second spring, the pressure plate can uniformly and stably squeeze and position the sound insulation cotton to prevent it from moving during cutting and ensure cutting accuracy. At the same time, the through groove allows the cutting blade to pass smoothly for cutting.

[0019] Compared with the prior art, the beneficial effects of this utility model are: the cutting device for processing honeycomb automotive sound insulation cotton;

[0020] 1. The angle positioning mechanism allows the positioning rod to disengage from the positioning groove when the pedal is pressed, enabling the cutting table to rotate flexibly. When the pedal is released, the positioning rod engages with the positioning groove under the action of the spring, achieving precise angle positioning. This design allows operators to easily adjust the cutting angle, perfectly meeting the different angle cutting needs of automotive sound insulation cotton, greatly improving the flexibility and adaptability of cutting. The cutting mechanism uses an electric slide table with a drive motor and cutting blade. The precise linear motion control of the electric slide table allows the cutting blade to move smoothly along the set path. The drive motor drives the cutting blade to rotate at high speed, generating powerful cutting force, improving the processing quality and production efficiency of the sound insulation cotton.

[0021] 2. The extrusion mechanism consists of a limiting plate, lifting rods, anti-reverse block, pressure plate, and second spring. When the cylinder pushes the lifting seat down, the pressure plate contacts the sound insulation cotton under the action of the second spring. Since the lifting rods are evenly distributed and can freely extend and retract within the limiting plate, the pressure plate can apply pressure evenly to the sound insulation cotton, effectively preventing the sound insulation cotton from shifting during the cutting process. The through groove corresponds to the position of the cutting blade, which does not affect the cutting operation and ensures the stable fixation of the sound insulation cotton, thus comprehensively ensuring the cutting accuracy and improving the product qualification rate.

[0029] 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.

[0030] Please see Figure 1-6 This utility model provides a technical solution: a cutting device for processing honeycomb automotive sound insulation cotton, including a support base 1, a fixed plate 2 fixedly installed in the middle of the support base 1, a rotating base 3 rotatably passing through the inside of the fixed plate 2, a cutting table 4 fixedly connected to the top of the rotating base 3, grooves 5 equally spaced on the surface of the cutting table 4, and an angle positioning mechanism connected between the rotating base 3 and the fixed plate 2 for angle positioning. The angle positioning mechanism includes a rotating plate 6 fixedly installed on the outer ring of the top of the rotating base 3, positioning grooves 7 equally spaced inside the rotating plate 6, and the bottom of the rotating base 3... A connecting bearing 8 is connected to the end of the connecting bearing 8. A connecting block 9 is connected to the bottom end of the connecting block 9. A limit rod 10 is fixedly installed at the bottom end of the connecting block 9. A baffle 11 is fixedly installed at the bottom of the limit rod 10. A lifting plate 12 is slidably arranged on the surface of the limit rod 10. A first spring 13 is sleeved on the outer ring of the limit rod 10 between the lifting plate 12 and the baffle 11. The lifting plate 12 and the baffle 11 form a telescopic structure through the first spring 13. Positioning rods 14 are fixedly installed at both ends of the lifting plate 12. The positioning rods 14 are movably engaged with the positioning groove 7. A pedal 15 is fixedly connected to the bottom end of the positioning rod 14.

[0031] In the above-described structure, when the angle of the cutting table 4 needs to be adjusted, the operator steps on the pedal 15. The pedal 15 drives the positioning rod 14 and the lifting plate 12, which are fixedly connected to it, to move downward. During this process, the lifting plate 12 compresses the first spring 13 on the limit rod 10, causing the positioning rod 14 to gradually disengage from the positioning groove 7 inside the rotating disk 6, thus releasing the angle lock on the rotating seat 3. Since the bottom end of the rotating seat 3 is connected to the limit rod 10 through the connecting bearing 8 and the connecting block 9, the rotating seat 3 can rotate freely after the positioning rod 14 disengages from the positioning groove 7. The operator can manually rotate the cutting table 4 according to the cutting requirements, thereby driving the rotating seat 3 and the rotating disk 6 to rotate to the appropriate angle.

[0032] Once the cutting table 4 reaches the target angle, the operator releases the pedal 15. At this time, the elastic force generated by the elastic deformation of the first spring 13 pushes the lifting plate 12 upward, causing the lifting plate 12 to drive the positioning rod 14 to return to its original position. The positioning rod 14 is then re-engaged into the positioning groove 7 at the corresponding position of the rotating disk 6, thereby achieving the angular positioning of the rotating seat 3 and the cutting table 4 and stabilizing the cutting table 4 at the required angle for subsequent cutting of honeycomb automotive sound insulation cotton.

[0033] Cylinders 16 are fixedly installed at both ends of the support base 1. A limit frame 17 is connected to the top of the cylinder 16. The limit frame 17 is slidably connected to both ends of the support base 1. A lifting seat 18 is fixedly connected to the top of the limit frame 17. A cutting mechanism is installed at the top rear end of the lifting seat 18 to realize the cutting work. The cutting mechanism includes an electric slide table 19 fixedly installed on the top rear side of the lifting seat 18. A connecting frame 20 is fixedly connected to the bottom surface of the sliding part of the electric slide table 19. A drive motor 21 is fixedly installed at the bottom end of the connecting frame 20. A cutting blade 22 is fixedly connected to the shaft end of the drive motor 21.

[0034] In the above structure design, after the sound insulation cotton is placed on the cutting table 4 and the angle is fixed by the angle positioning mechanism, the cylinders 16 at both ends of the support seat 1 start to work. The cylinders 16 pull down the limit frame 17, thereby driving the lifting seat 18 to slide down along both ends of the support seat 1, so that the cutting mechanism installed at the top rear end of the lifting seat 18 moves closer to the sound insulation cotton. When the lifting seat 18 reaches the appropriate position, the cutting mechanism starts to run.

[0035] As the core driving component, the electric slide table 19 has an internal drive system that controls the sliding part to move linearly along the slide rail according to a pre-set program or instructions input by the operator. The sliding part drives the connecting frame 20, which is fixedly connected to it, to move horizontally. The connecting frame 20 then drives the drive motor 21 and the cutting blade 22 at the bottom to move synchronously. At the same time, the drive motor 21 starts, and its shaft drives the cutting blade 22 to rotate at high speed, generating a strong cutting force. Under the precise control of the electric slide table 19, the high-speed rotating cutting blade 22 performs cutting work on the sound insulation cotton according to the set trajectory. After completing one cutting stroke, the electric slide table 19 controls the cutting blade 22 to reset, and the cylinder 16 drives the lifting seat 18 and the cutting mechanism to rise, so as to perform the next cutting operation or remove the cut sound insulation cotton.

[0036] The extrusion mechanism is installed on the top inner side of the lifting seat 18 for extrusion positioning. The extrusion mechanism includes a limiting plate 23 fixedly installed on the inner side of the lifting seat 18. A lifting rod 24 slides through the inside of the limiting plate 23. The lifting rods 24 are evenly distributed inside the limiting plate 23. A stop block 25 is fixedly installed at the top of the lifting rod 24. A pressure plate 26 is fixedly connected to the bottom of the lifting rod 24. A second spring 27 is sleeved on the outer ring of the lifting rod 24 between the pressure plate 26 and the limiting plate 23. The pressure plate 26 and the limiting plate 23 are telescopically connected by the second spring 27. A through groove 28 is opened inside the pressure plate 26. The position of the through groove 28 corresponds to the position of the cutting blade 22.

[0037] In the honeycomb automotive sound insulation cotton cutting process described above, the operation of the extrusion mechanism and the action of the cutting mechanism are closely coordinated. When the cylinder 16 drives the limiting frame 17 and the lifting seat 18 to move towards the sound insulation cotton, the extrusion mechanism installed on the inner side of the top of the lifting seat 18 descends accordingly. During the descent, the pressure plate 26 first contacts the surface of the sound insulation cotton. Since the lifting rods 24 are evenly distributed within the limiting plate 23 and can slide freely, and the pressure plate 26 and the limiting plate 23 are telescopically connected by the second spring 27, when the pressure plate 26 is blocked by the sound insulation cotton, the first spring 27... The second spring 27 is compressed, and under the elastic force of the second spring 27, the pressure plate 26 applies pressure evenly to the sound insulation cotton, firmly squeezing and fixing the sound insulation cotton on the cutting table 4, effectively preventing the sound insulation cotton from shifting or sliding during the cutting process, and ensuring the stability of the cutting operation. When the cutting mechanism is running, the high-speed rotating cutting blade 22 can smoothly pass through the through groove 28 to cut the sound insulation cotton fixed by the pressure plate 26. The through groove 28 not only ensures the normal cutting path of the cutting blade 22, but also does not affect the squeezing and positioning effect of the pressure plate 26 on the sound insulation cotton.

[0038] This completes a series of tasks. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0039] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
