Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automobile sound-absorbing cotton production, in particular to an automobile sound-absorbing cotton production forming equipment and a forming method thereof. BACKGROUND

[0002] In the field of modern automobile manufacturing, sound-absorbing cotton, as an important sound insulation and noise reduction material, is widely used in various parts of the vehicle body, such as the engine compartment, doors, roofs, and interior floor, to improve the comfort and noise control performance of the vehicle. The manufacturing process of traditional sound-absorbing cotton usually includes raw material mixing, melt spinning, fiber accumulation, hot pressing, cutting, and other steps. The forming process plays a decisive role in the physical properties, density distribution, and dimensional stability of the final product. Most of the current sound-absorbing cotton forming equipment has low automation, high energy consumption, and unstable pressing effect, especially in temperature control, pressure regulation, and mold adaptation, which lacks fine management, resulting in uneven density, poor elasticity, and insufficient resilience of sound-absorbing cotton products, which cannot meet the strict requirements of high-end vehicle noise control. Therefore, developing a sound-absorbing cotton production forming equipment with reasonable structure, stable operation, and multi-parameter linkage control has become a key technical direction for automobile parts manufacturers to improve product quality and production efficiency.

[0003] The existing sound-absorbing cotton forming technology mostly uses fixed molds with hot pressing mechanisms for shaping operations, but when facing the needs of sound-absorbing materials with different thicknesses, densities, and shapes, the adaptability of the equipment is poor, and frequent mold replacement not only affects the production rhythm but also increases maintenance and management costs.

[0004] In view of the above situation, in order to overcome the above technical problems, the present application designs an automobile sound-absorbing cotton production forming equipment and a forming method thereof, which solves the above technical problems. SUMMARY

[0005] The technical purpose to be achieved by the present application is to design an automobile sound-absorbing cotton production forming equipment and a forming method thereof, which improves the adaptability of the equipment and reduces the time for replacing molds.

[0006] In order to achieve the above technical purpose, the present application provides the following technical scheme:

[0007] The application relates to an automobile sound-absorbing cotton production forming equipment, which mainly comprises a forming machine, a controller, a moving machine, a fixing mechanism, a forming mechanism, a support, a forming frame and a driving cylinder and the like key components. The forming machine in the equipment is installed on the bottom platform of the equipment and serves as the main bearing structure of the whole system, thereby providing firm and stable support. The controller is installed in the interior of the forming machine and is used for intelligently controlling and adjusting parameters such as temperature, pressure, time and the like key forming parameters of the whole set of equipment, so as to ensure the precision and consistency of the forming process. The moving machine is installed above the forming machine and is used for driving the upper mechanism to move horizontally or longitudinally, thereby realizing switching and coordinated operation between multiple stations and improving the automation level of the equipment. The fixing mechanism is arranged on the side of the moving machine and ensures the stability of the forming die during the running process through precise alignment. The forming mechanism is installed on the outside of the fixing mechanism and is the core component for realizing heating and pressing of the sound-absorbing cotton and forming and shaping.

[0008] In addition, the equipment further comprises a support installed above the forming machine and used for supporting the forming frame structure, the forming frame is installed on the side of the support and provides a stable fulcrum for the driving cylinder. The driving cylinder is installed above the forming frame and drives each component to move up and down through pneumatic control, so as to complete the pressing and demolding of the sound-absorbing cotton material and the like operation process. The driving motor is further arranged in the interior of the fixing mechanism, the driving motor drives the rotating component to operate, the locking component arranged in the interior is rotated, the fixing limiting block is accurately clamped into the fixing clamping groove arranged in the locking component, the positioning and fixing effects are achieved, and the quick connection and stable support of multiple forming mechanisms are realized. The structure design not only enhances the running stability of the equipment, but also improves the convenience and operation safety of die replacement, and is overall beneficial to improving the sound-absorbing cotton production efficiency and product quality.

[0009] The fixing mechanism comprises an installation rod, a fixing rod, a driving motor, a rotating component and a locking component, and the structure design is reasonable and hierarchical. The installation rod is arranged on the side of the moving machine and serves as support and connection, thereby providing an installation basis for subsequent components. The fixing rod is installed on the side of the installation rod and is used for enhancing the stability and bearing capacity of the structure. The driving motor is installed on the back of the fixing rod and serves as a power source, thereby providing rotating driving force for the whole fixing mechanism. The rotating component is installed in front of the driving motor and realizes the rotating movement of the locking mechanism by receiving the torque output by the driving motor. The locking component is installed at the front end of the rotating component and is used for connecting and fixing with the external forming mechanism. Through the cooperation of the series, the whole fixing mechanism can realize the quick locking and releasing of the sound-absorbing cotton forming mechanism, improve the die replacement efficiency, and ensure the positioning precision and running safety in the forming process.

[0010] The driving motors are installed on the fixed rod in an equidistant manner, which not only helps to balance the stress distribution during equipment operation, but also improves the stability and durability of the entire fixing mechanism under high-frequency operation. Equidistant arrangement can effectively avoid the mechanism deflection or component wear caused by uneven stress, which is beneficial to prolong the service life of the equipment. At the same time, the driving motor, rotating assembly and locking assembly are coaxially installed to ensure the high-precision coaxial operation of the moving parts during transmission, reducing the energy loss and deviation transmission in mechanical movement. This structure design can realize efficient conduction of power output, improve the response speed and positioning accuracy of the locking assembly during rotation, thereby ensuring reliable locking and quick unlocking of the forming mechanism during operation, and greatly improving the automation level and production efficiency of the sound-absorbing cotton forming equipment.

[0011] The rotating assembly includes a fixed sleeve, a rotating sleeve and a rotating clamping strip, and the components are compactly structured and tightly matched. The fixed sleeve is installed at the front end of the fixed rod to provide a stable mounting base for the entire rotating structure, ensuring that it does not shift or loosen during equipment operation. The rotating sleeve is arranged inside the fixed sleeve and can rotate around the fixed sleeve. It is made of wear-resistant metal material to ensure good mechanical properties even after long-term high-frequency operation. The rotating clamping strip is installed on the inner surface of the rotating sleeve and serves as a key component for connecting and transmitting the locking assembly, enabling accurate rotational movement under the action of the driving motor. This rotating assembly realizes precise control of the locking structure through the rotational cooperation between the inner and outer sleeves and the limiting action of the clamping strip, ensuring transmission efficiency while enhancing the overall operation stability and reliability of the equipment.

[0012] The locking assembly includes a rotating block, a rotating clamping groove, a fixed block and a fixed limiting block, with a scientific and reasonable structure design and good locking performance. The rotating block is installed inside the rotating assembly and serves as the core element connecting the transmission system and the locking mechanism, enabling synchronous rotation under the action of the driving motor. The rotating clamping groove is opened on the outer surface of the rotating block to form a fitting relationship with the rotating clamping strip, realizing stable rotational transmission. The fixed block is installed above the rotating block as a structural support and force transmission node, further transmitting the movement of the rotating block to the locking end. The fixed limiting block is installed at the top edge of the fixed block to mechanically limit the cooperation with other forming components, realizing quick and reliable positioning and locking. The edges of the fixed limiting block are rounded to effectively reduce wear and damage caused by frequent contact, while improving the safety and service life of the structure. The locking assembly operates in harmony to realize efficient clamping and release of the forming mechanism, meeting the high requirements of quick die changing and precise positioning for automatic sound-absorbing cotton production equipment.

[0013] The forming mechanism includes a forming block, a forming groove and a fixing hole, which is the key functional unit to realize the shaping processing of sound-absorbing cotton. The forming block is installed on the side of the fixing mechanism as the main component for bearing and supporting the forming structure, and its material is usually selected from high-strength and high-temperature-resistant alloy materials to ensure good stability and durability during hot pressing. The forming groove is opened on the upper surface of the forming block and is used to accommodate sound-absorbing cotton materials with predetermined shape and thickness. The inner groove can be designed into different geometric shapes according to actual needs to adapt to the sound-absorbing structure required by various automobile parts. The size and depth of the forming groove are precisely processed to ensure the excellent performance of the sound-absorbing cotton products in terms of size consistency and density distribution. The fixing hole is opened on the side of the forming block as a mounting hole, which can be firmly fixed on the fixing mechanism through bolts or latches, facilitating maintenance and replacement. The whole forming mechanism is compact in structure and convenient to operate, which helps to improve the forming precision and production efficiency of sound-absorbing cotton products.

[0014] The side surface of the forming block is provided with a clamping limiting groove and a clamping guide groove, which are mainly used for precise mechanical connection and position positioning with matching components. The clamping limiting groove can effectively limit the lateral movement of the forming block during equipment operation, ensuring that it always maintains a stable working posture during the forming operation and avoiding position deviation caused by vibration or uneven stress. The clamping guide groove is used to guide the clamping component to smoothly insert and align, improving the efficiency and accuracy of the assembly process. At the same time, the other side surface of the forming block is installed with a clamping limiting block and a clamping guide block matched therewith. These structures realize firm fitting through convex-concave matching, which not only enhances the overall connection strength, but also facilitates subsequent disassembly and maintenance. The clamping guide block provides good guiding effect at the initial stage of butt joint, making the components not easy to deflect or jam in rapid assembly, improving the stability of automatic assembly. The overall structure design fully embodies the modularization and high-precision manufacturing concept, providing strong structural guarantee for the reliable operation of the sound-absorbing cotton forming equipment.

[0015] The cross-sectional shape of the clamping limiting groove and the clamping limiting block adopts a trapezoidal design. This geometric structure not only enhances the tightness between the components, but also effectively improves the locking strength and resistance to lateral displacement. The trapezoidal cross-section, with its wide base and narrow top design, allows the clamping limiting block to be firmly embedded in the limiting groove, preventing loosening or falling under mechanical vibration or external force, ensuring the stability and safety of the forming block during operation. At the same time, the trapezoidal structure facilitates self-locking effect, improving the overall reliability of the equipment. On the other hand, the cross-sectional shape of the clamping guide groove and the clamping guide block is designed as a circle. This design helps to achieve smooth guidance and rotation function. The circular cross-section can reduce the frictional resistance of the components during insertion and alignment, allowing the guide block to slide smoothly into the guide groove, improving assembly efficiency and reducing wear. In addition, the circular structure has uniform stress distribution under stress, which helps to prolong the service life of the guide assembly. Overall, the combination of trapezoidal and circular cross-sections achieves efficient cooperation and reliable operation of the mechanical structure.

[0016] The inside of the fixing hole is designed with two structures of fixing limiting groove and fixing clamping groove, which jointly act to realize the stable installation and accurate positioning of the forming block. The fixing limiting groove is opened on the inner surface of the fixing hole, which limits the axial and radial movement of the installation part in the hole, effectively preventing the forming block from shifting or loosening under stress, thereby ensuring the operation stability of the overall equipment. At the same time, the fixing clamping groove is arranged on the bottom surface of the fixing hole, and the cross-sectional shape is designed as a fan ring. This shape not only enhances the carrying capacity of the clamping groove, but also allows the clamping groove and the corresponding clamping component to achieve a tight fit. The fan ring design allows the clamping component to smoothly slide in and be securely locked when inserted, effectively improving the assembly efficiency of the equipment and the safety of mechanical connection. In addition, this structure is convenient for dealing with vibration and impact generated during the forming process, ensuring that the forming block still maintains good fixing effect in a high-frequency operating environment, thereby improving the overall performance and reliability of the sound-absorbing cotton production forming equipment.

[0017] An automobile sound-absorbing cotton production forming method, which is used in cooperation with the above-mentioned automobile sound-absorbing cotton production forming equipment; characterized in that: the steps of the method are as follows:

[0018] S1: The staff selects the forming mechanism with appropriate forming groove according to the shape required by the automobile sound-absorbing cotton, and installs the forming plate on the fixing mechanism by cooperating the fixing limiting groove and the fixing block on the fixing limiting block on the side of the fixing hole of the forming mechanism;

[0019] S2: Start the driving motor, and the driving motor drives the rotating sleeve to rotate inside the fixed sleeve. The rotating sleeve drives the rotating block to rotate under the cooperation of the rotating clamping strip and the rotating clamping groove, so that the fixing block rotates by a certain angle;

[0020] S3: The fixed limiting block is rotated into the fixed clamping groove for clamping and fixing, the fixing mechanism fixes the plurality of forming mechanisms on the side surface, and relies on the mobile machine to drive the position adjustment;

[0021] S4: The staff places the raw material of the sound-absorbing cotton on the forming mechanism, controls the driving cylinder to drive the structure inside the forming frame to move downward, covers the forming mechanism, and realizes the sound-absorbing cotton manufacturing.

[0022] The beneficial effects of the present application are as follows:

[0023] (1) The automobile sound-absorbing cotton production forming equipment disclosed by the present application realizes high automation and precise control of the sound-absorbing cotton forming process through reasonable structure design and collaborative work of key components. The built-in intelligent controller can monitor and adjust parameters such as temperature, pressure and forming time in real time, ensuring that the sound-absorbing cotton material is uniformly heated and compacted during the forming process, thereby improving the density consistency and physical properties of the finished product. The fixing mechanism and the forming mechanism are made of high-strength materials, and the rotating assembly and the locking assembly are driven by the driving motor to realize rapid and stable mold switching and positioning, significantly shortening the production cycle and reducing manual operation errors. In addition, the close cooperation between the forming block and the fixing mechanism ensures the stability of the mold during the forming process, avoiding product deformation or quality fluctuations caused by vibration or displacement, and improving the reliability of the production line and the qualification rate of the product.

[0024] (2) The compact and modular design of the equipment structure facilitates maintenance and upgrading, reducing the cost of later maintenance. The reasonable geometric design of the clamping limiting groove and the clamping guide groove, as well as the fan-shaped clamping groove design in the fixing hole, ensures the stable connection and precise alignment between the components, improving the durability and operation safety of the mechanical structure. The coaxial design of the driving motor and the rotating assembly improves the power transmission efficiency and reduces energy loss, so that the equipment can still run smoothly under high frequency operation. Overall, the present application not only improves the production efficiency and finished product quality of automobile sound-absorbing cotton, but also meets the strict requirements of modern automobile manufacturing for environmentally friendly, energy-saving and high-performance sound insulation materials, and has significant market application value and promotion prospects.

[0037] In order to better understand the above technical solutions, the above technical solutions will be described in detail below in combination with the drawings in the specification and specific embodiments.

[0038] As Figures 1-8As shown, an automobile sound-absorbing cotton production forming equipment mainly includes key components such as a forming machine 1, a controller 2, a moving machine 3, a fixing mechanism 4, a forming mechanism 5, a support 6, a forming frame 7, and a driving cylinder 8. The forming machine 1 in the equipment is installed on the bottom platform of the equipment, serving as the main bearing structure of the entire system and providing solid and stable support. The controller 2 is installed inside the forming machine 1, used to realize intelligent control and parameter adjustment of the running state of the entire equipment, such as temperature, pressure, time, and other key forming parameters, to ensure the precision and consistency of the forming process. The moving machine 3 is installed above the forming machine 1, used to drive the upper mechanism to move horizontally or vertically, realize switching and coordinated operation between multiple stations, and improve the automation level of the equipment. The fixing mechanism 4 is arranged on the side of the moving machine 3, ensuring the stability of the forming mold during operation through precise alignment. The forming mechanism 5 is installed outside the fixing mechanism 4, which is the core component for realizing the heating and pressing of sound-absorbing cotton and forming.

[0039] In addition, the equipment also includes a support 6 installed above the forming machine 1, used to support the forming frame 7 structure. The forming frame 7 is installed on the side of the support 6 and provides a stable fulcrum for the driving cylinder 8. The driving cylinder 8 is installed above the forming frame 7 and drives each component to move up and down through pneumatic control, completing the pressing and demolding operations of sound-absorbing cotton materials. Inside the fixing mechanism 4, there is also a driving motor 43. The driving motor 43 drives the rotating component 44 to operate, causing the locking component 45 inside to rotate, thereby driving the fixed limiting block 454 to accurately clamp into the fixed clamping groove 532 inside the locking component 45, achieving positioning and fixing, and realizing the quick connection and stable support of multiple forming mechanisms 5. This structure design not only enhances the running stability of the equipment, but also improves the convenience and operation safety of mold replacement, which is overall beneficial to improving the production efficiency and product quality of sound-absorbing cotton.

[0040] As Figure 4As shown, the fixing mechanism 4 includes a mounting rod 41, a fixing rod 42, a drive motor 43, a rotating assembly 44, and a locking assembly 45, with a reasonable and well-defined structure. The mounting rod 41 is located on the side of the mobile machine 3, serving as support and connection, providing a foundation for subsequent components. The fixing rod 42 is mounted on the side of the mounting rod 41 to enhance the stability and load-bearing capacity of the structure. The drive motor 43 is mounted on the back of the fixing rod 42, serving as a power source to provide rotational driving force for the entire fixing mechanism 4. The rotating assembly 44 is mounted in front of the drive motor 43, receiving the torque output from the drive motor 43 to achieve the rotational movement of the locking mechanism. The locking assembly 45 is mounted at the front end of the rotating assembly 44 for connection and fixation with the external molding mechanism 5. Through this series of actions, the entire fixing mechanism 4 can quickly lock and release the sound-absorbing cotton molding mechanism 5, improving mold change efficiency and ensuring positioning accuracy and operational safety during the molding process.

[0041] The drive motors 43 are mounted on the fixed rods 42 at equal intervals. This arrangement not only helps to balance the force distribution during equipment operation but also improves the stability and durability of the entire fixed mechanism 4 under high-frequency operation. The equal-interval arrangement effectively avoids mechanism sway or component wear caused by uneven force distribution, thus extending the equipment's service life. Simultaneously, the drive motors 43, rotating components 44, and locking components 45 are coaxially mounted, ensuring high-precision coaxial operation of each moving part during transmission and reducing energy loss and deviation transmission in mechanical motion. This structural design enables efficient power output transmission, improves the response speed and positioning accuracy of the locking components 45 during rotation, thereby ensuring reliable locking and rapid unlocking of the forming mechanism 5 during operation, significantly improving the automation level and production efficiency of the sound-absorbing cotton forming equipment.

[0042] like Figure 5 As shown, the rotating assembly 44 includes a fixed sleeve 441, a rotating sleeve 442, and a rotating retaining bar 443. The components are compactly structured and tightly fitted. The fixed sleeve 441 is installed at the front end of the fixed rod 42, providing a stable mounting base for the entire rotating structure and ensuring it does not shift or loosen during operation. The rotating sleeve 442 is located inside the fixed sleeve 441 and can rotate around it. It is made of wear-resistant metal to maintain good mechanical performance under long-term high-frequency operation. The rotating retaining bar 443 is installed on the inner surface of the rotating sleeve 442 and serves as a key component for connection and transmission with the locking assembly 45. It can achieve accurate rotation under the drive of the motor 43. This rotating assembly 44, through the rotational cooperation between the inner and outer sleeves combined with the limiting effect of the retaining bar, achieves precise control of the locking structure, ensuring transmission efficiency while enhancing the overall operational stability and reliability of the equipment.

[0043] As Figure 6 shown, the locking assembly 45 includes a rotating block 451, a rotating clamping groove 452, a fixed block 453, and a fixed limiting block 454, which are scientifically designed and have good locking performance. The rotating block 451 is installed inside the rotating assembly 44 and serves as a core element connecting the transmission system and the locking mechanism, which can rotate synchronously under the action of the driving motor 43. The rotating clamping groove 452 is formed on the outer surface of the rotating block 451 and is used to form a fitting relationship with the rotating clamping strip 443 to achieve stable rotation transmission. The fixed block 453 is installed above the rotating block 451 and serves as a structural support and force transmission transition node to further transmit the movement of the rotating block 451 to the locking end. The fixed limiting block 454 is installed at the top edge of the fixed block 453 and is used to mechanically limit the cooperation with other formed parts to achieve quick and reliable positioning and locking. The edge of the fixed limiting block 454 is rounded to effectively reduce wear and damage caused by frequent contact, while improving the safety and service life of the structure. The locking assembly 45 operates in coordination as a whole to achieve efficient clamping and release of the forming mechanism 5, meeting the high requirements of quick mold changing and precise positioning of automatic sound-absorbing cotton production equipment.

[0044] As Figure 7 shown, the forming mechanism 5 includes a forming block 51, a forming groove 52, and a fixed hole 53, which is a key functional unit for realizing the shaping of sound-absorbing cotton. The forming block 51 is installed on the side of the fixing mechanism 4 and serves as a main component for bearing and supporting the forming structure. It is usually made of high-strength and high-temperature-resistant alloy materials to ensure good stability and durability during hot pressing. The forming groove 52 is formed on the upper surface of the forming block 51 and is used to accommodate sound-absorbing cotton materials with predetermined shapes and thicknesses. The inner groove can be designed in different geometric shapes according to actual needs to adapt to the sound-absorbing structures required by various automobile parts. The size and depth of the forming groove 52 are precisely processed to ensure the excellent performance of the shaped sound-absorbing cotton products in terms of size consistency and density distribution. The fixed hole 53 is formed on the side of the forming block 51 and serves as a mounting hole. It can be firmly fixed on the fixing mechanism 4 through bolts or latches, which is convenient for maintenance and replacement. The entire forming mechanism 5 is compact in structure and easy to operate, which helps to improve the forming precision and production efficiency of sound-absorbing cotton products.

[0045] The side of the forming block 51 is provided with a clamping limiting groove 511 and a clamping guide groove 512, which are mainly used for precise mechanical connection and position positioning with matching components. The clamping limiting groove 511 can effectively limit the lateral movement of the forming block 51 during equipment operation, ensuring that it always maintains a stable working posture during the forming operation, avoiding position deviation caused by vibration or uneven stress. The clamping guide groove 512 is used to guide the smooth insertion and alignment of the clamping component, improving the efficiency and accuracy of the assembly process. At the same time, the other side of the forming block 51 is installed with a clamping limiting block 513 and a clamping guide block 514 that cooperate with it. These structures realize firm fitting through convex-concave cooperation, which not only enhances the overall connection strength, but also facilitates subsequent disassembly and maintenance. The clamping guide block 514 provides good guiding effect at the initial stage of docking, making the component not easy to deviate or jam in rapid assembly, improving the stability of automatic assembly. The overall structural design fully embodies the modularization and high-precision manufacturing concept, providing strong structural guarantee for the reliable operation of the sound-absorbing cotton forming equipment.

[0046] The cross-sectional shape of the clamping limiting groove 511 and the clamping limiting block 513 adopts a trapezoidal design, which not only enhances the tightness of the components, but also effectively improves the locking strength and resistance to lateral displacement. The trapezoidal cross-section design with wide base and narrow top allows the clamping limiting block 513 to be firmly embedded in the limiting groove, avoiding loosening or falling under mechanical vibration or external force, ensuring the stability and safety of the forming block 51 during operation. At the same time, the trapezoidal structure facilitates self-locking effect, improving the overall reliability of the equipment. On the other hand, the cross-sectional shape of the clamping guide groove 512 and the clamping guide block 514 is designed as a circle, which helps to achieve smooth guidance and rotation function. The circular cross-section can reduce the frictional resistance of the components during insertion and alignment, allowing the guide block to slide smoothly into the guide groove, improving assembly efficiency and reducing wear. In addition, the circular structure has uniform stress distribution when stressed, which helps to prolong the service life of the guide assembly. Overall, the combination of trapezoidal and circular cross-sections realizes efficient cooperation and reliable operation of the mechanical structure.

[0047] As Figure 8As shown, the internal design of the fixing hole 53 includes two structures: a fixing limiting groove 531 and a fixing slot 532. These structures work together to achieve stable installation and precise positioning of the molding block 51. The fixing limiting groove 531 is formed on the inner surface of the fixing hole 53, which restricts the axial and radial movement of the installed parts within the hole, effectively preventing the molding block 51 from shifting or loosening under stress, thereby ensuring the overall operational stability of the equipment. Meanwhile, the fixing slot 532 is located on the bottom surface of the fixing hole 53, and its cross-sectional shape is designed as a fan-shaped ring. This shape not only enhances the load-bearing capacity of the slot but also allows for a tight fit between the slot and the corresponding snap-fit ​​component. The fan-shaped ring design allows the snap-fit ​​component to slide smoothly into and lock securely during insertion, effectively improving the assembly efficiency and mechanical connection safety of the equipment. Furthermore, this structure facilitates the handling of vibrations and impacts generated during the molding process, ensuring that the molding block 51 maintains good fixation even in high-frequency operating environments, thereby improving the overall performance and reliability of the sound-absorbing cotton production molding equipment.

[0048] A method for producing automotive sound-absorbing cotton, the method being used in conjunction with the aforementioned automotive sound-absorbing cotton production and molding equipment; characterized in that the steps of the method are as follows:

[0049] S1: The staff selects a molding mechanism 5 with a suitable molding groove 52 according to the required shape of the car sound-absorbing cotton, and installs the molding plate on the fixing mechanism 4 by using the fixing limit groove 531 and the fixing limit block 454 on the fixing block 453 to fix the fixing holes 53 on the side of the multiple molding mechanisms 5.

[0050] S2: Start the drive motor 43. The drive motor 43 drives the rotating sleeve 442 to rotate inside the fixed sleeve 441. The rotating sleeve 442 drives the rotating block 451 to rotate under the cooperation of the rotating retainer 443 and the rotating retainer 452, so that the fixed block 453 rotates at a certain angle.

[0051] S3: The fixed limit block 454 rotates into the fixed slot 532 for locking and fixing. The fixing mechanism 4 fixes multiple forming mechanisms 5 on the side and relies on the moving machine 3 to drive them to adjust their positions.

[0052] S4: The staff places the sound-absorbing cotton raw material on the molding mechanism 5, and controls the drive cylinder 8 through the controller 2 to drive the internal structure of the molding frame 7 to move downward and cover the molding mechanism 5, thereby realizing the manufacturing and molding of the sound-absorbing cotton.

[0053] In the working process of the application, the workers select the forming mechanism 5 with the corresponding forming groove 52 according to the specific shape required by the automobile sound-absorbing cotton. In order to ensure the stable operation of the equipment and the forming precision, the workers accurately match the fixing holes 53 on the side of the forming mechanism 5 with the fixing limiting blocks 454 on the fixing block 453 through the fixing limiting grooves 531, and firmly install the forming block 51 on the fixing mechanism 4. The accurate installation of this link provides a solid foundation for subsequent automated operation, while ensuring the stability and repeatability of the forming structure. The workers start the driving motor 43, and the driving motor 43 drives the rotating sleeve 442 installed on the fixing rod 42 to rotate smoothly inside the fixing sleeve 441. The rotating sleeve 442 drives the rotating block 451 inside to rotate through the close cooperation with the rotating clamping strip 443 and the rotating clamping groove 452, so as to rotate the fixing block 453 by a certain angle. This rotation creates conditions for the quick and firm positioning of the fixing mechanism 4. Then, with the fixing limiting block 454 rotating into the fixing clamping groove 532, the clamping and fixing are realized, and the multiple forming mechanisms 5 are stably fixed on the side of the fixing mechanism 4. At this time, the moving machine 3 drives the entire fixing mechanism 4 and the forming mechanism 5 to make accurate position adjustment, ensuring the correct positioning and coordinated action of the forming area. Finally, the workers place the sound-absorbing cotton raw material prepared in advance above the forming mechanism 5.
