Description

Technical Field

[0001] This utility model relates to the field of cutting device technology, and in particular to an auxiliary cutting device for acoustic mesh production. Background Technology

[0002] As a key component of loudspeakers, acoustic instruments, and other equipment, acoustic mesh must possess both sound transmission performance and structural stability. Its production process demands stringent requirements for cutting precision and edge quality. Traditional cutting methods have several drawbacks: manual cutting is inefficient and prone to dimensional deviations, making it difficult to meet the needs of mass production; ordinary mechanical cutting equipment often results in rough edges and material wrinkles due to the thinness of the mesh and the ease with which fibers slip, affecting the sealing performance of subsequent assembly.

[0003] Existing automated cutting equipment largely relies on complex sensors for correction and positioning, which is not only costly but also prone to misjudgment due to fiber interference in the processing of flexible materials such as yarn. Furthermore, traditional cutting blades have poor compatibility with the yarn fiber structure, easily causing filament pulling and fiber breakage. In addition, problems such as scattered material stacking after cutting and low material collection efficiency also restrict the improvement of the continuity and consistency of acoustic yarn production. Therefore, there is an urgent need for a simple and highly adaptable auxiliary cutting device to solve these problems.

[0004] The existing auxiliary cutting device for acoustic mesh production has not solved the problem of enabling more precise cutting operations, reducing product quality issues caused by instability in cutting, improving production efficiency and product quality, and meeting the requirements for cutting stability and precision in acoustic mesh production. Therefore, we propose an auxiliary cutting device for acoustic mesh production. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies that lack precision in cutting operations, reduce product quality issues caused by unstable cutting, improve production efficiency and product quality, and meet the requirements for cutting stability and precision in the production of acoustic mesh. Therefore, this invention proposes an auxiliary cutting device for acoustic mesh production.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An auxiliary cutting device for acoustic mesh production includes a fixed base and a transport assembly. The transport assembly is fixedly connected to the top of the fixed base. The transport assembly includes a protective mounting frame, which is mounted on the fixed base. A first set of vertically mounted hydraulic cylinders is fixedly connected to the upper surface of the inner wall of the protective mounting frame. A square mounting frame is fixedly connected to the lower end of the first set of vertically mounted hydraulic cylinders. Two sets of supporting shafts are rotatably connected to the left and right sides of the inner wall of the square mounting frame. Two lower mounting frames are fixedly connected to the upper surface of the fixed base perpendicular to the lower end of the square mounting frame. Two active rotating columns are rotatably connected to the middle of the two lower mounting frames. Three sets of driven rotating columns are fixedly connected to one side of the two active rotating columns and inside the square mounting frame.

[0008] As a further improvement of this utility model: the driven rotating column located in the middle of the square mounting frame is installed in the middle of the two sets of supporting rotating shafts, and two servo motors are fixedly connected to one side of each of the two lower mounting frames.

[0009] By installing the driven rotating column in the middle of two sets of support shafts, stable support is achieved for the driven rotating column, ensuring its stable position during rotation and thus making the transportation of the mesh smoother. Simultaneously, two servo motors are installed to provide power, achieving efficient drive of the entire transportation component and ensuring fast and stable transportation of the mesh.

[0010] As a further embodiment of this utility model: the output ends of the two servo motors are rotatably connected to two sets of driving pulleys, and two sets of driven pulleys are rotatably connected to one side of the driving pulleys. The two sets of driving pulleys and the two sets of driven pulleys are connected by a transmission belt.

[0011] A servo motor drives the drive pulley to rotate, transmitting the motor's power to it and providing initial power to the transmission system. The drive pulley then drives the driven pulley via a transmission belt. The transmission belt ensures efficient power transfer, allowing the driven and drive pulleys to rotate synchronously, thus guaranteeing a stable transmission process.

[0012] As a further improvement of this utility model: three sets of rollers are rotatably connected to the surfaces of the two active rotating columns and the three sets of driven rotating columns, and rubber anti-slip sleeves are fixedly connected to the surfaces of the three sets of rollers.

[0013] By connecting rollers to the surfaces of the driving and driven rotating columns, the rotation of the rotating columns drives the rotation of the rollers, thus providing direct power for the transport of the yarn. Rubber anti-slip sleeves are installed on the roller surfaces; the increased friction between the rubber sleeves and the yarn ensures stable transport of the yarn, preventing slippage during transport and ensuring transport accuracy.

[0014] As a further embodiment of this utility model: a controller is fixedly connected to the surface of the square mounting bracket, a square hole is opened on the upper surface of the square mounting bracket, and a cutting component is fixedly connected to the top of the square hole. The cutting component includes a second set of vertically mounted hydraulic cylinders, and a cutting mounting bracket is fixedly connected to the lower end of the second set of vertically mounted hydraulic cylinders.

[0015] By fixing a controller to the surface of the square mounting bracket, centralized control of the entire device is achieved, allowing operators to precisely control the operation of each component as needed. Square holes are made in the square mounting bracket to provide a channel for the cutting blade of the cutting assembly to descend, ensuring that the cutting blade accurately reaches the cutting position. A second set of vertically mounted hydraulic cylinders is connected to the cutting mounting bracket. The extension and retraction of the hydraulic cylinders drives the cutting mounting bracket to move up and down, thereby controlling the raising and lowering of the cutting blade to meet different cutting requirements.

[0016] As a further improvement of this utility model: a cutting blade is fixedly connected to the bottom of the cutting mounting bracket, and two L-shaped mounting brackets are fixedly connected to both sides of the cutting mounting bracket.

[0017] By fixing a cutting blade to the bottom of the cutting mounting frame, cutting power is transmitted to the cutting blade to achieve the purpose of cutting the mesh. L-shaped mounting brackets are connected to both sides of the cutting mounting frame. The cooperation between the L-shaped mounting brackets and the cutting base provides positioning and stable support for the cutting mounting frame, ensuring accurate cutting blade positioning during the cutting process and improving cutting quality.

[0018] A cutting seat is fixedly connected to the top of the fixed base perpendicular to the lower end of the cutting mounting bracket, and two grooves are opened on the left and right sides of the upper surface of the cutting seat.

[0019] By connecting a cutting base to the top of the fixed base, a stable support foundation is provided for the cutting operation, ensuring the stability of the device throughout the cutting process. Two grooves are formed on the upper surface of the cutting base, which, by engaging with the lower end of the L-shaped mounting bracket, achieve precise positioning of the cutting mounting bracket, further improving cutting stability and accuracy.

[0020] Compared with the prior art, this utility model provides an auxiliary cutting device for acoustic mesh production, which has the following advantages:

[0021] 1. This utility model uses two servo motors fixedly connected to one side of two lower mounting brackets as the power source for the transport component. After the motors start, they transmit rotational power through two sets of drive pulleys rotatably connected to their output ends. The drive pulleys are connected to two sets of driven pulleys located on one side of them via a transmission belt. This connection method utilizes the flexibility and friction of the transmission belt to smoothly transmit the rotation of the drive pulleys to the driven pulleys, thereby driving the drive rotating column connected to the driven pulleys and the driven rotating column in the square mounting bracket to rotate together. Through this power transmission system, reliable power is provided for the transport of the mesh, ensuring that the mesh can move continuously on the device.

[0022] Three sets of rollers, rotatably connected to the surfaces of the driving and driven rotating columns, rotate synchronously with the rotating columns. Rubber anti-slip sleeves fixedly connected to the roller surfaces, when in contact with the mesh, utilize the friction of the rubber anti-slip sleeves to convert the circular motion of the rollers into the linear motion of the mesh, thus transporting the mesh on the device. This design not only ensures smooth mesh transport but also adaptively adjusts the friction between the rubber anti-slip sleeves and the mesh to accommodate the transport needs of meshes of different materials and thicknesses, achieving stable transport regardless of mesh size or material.

[0023] The driven rotating column in the center of the square mounting bracket is installed between two sets of support shafts. This structural design provides stable support for the driven rotating column, ensuring its smooth rotation and consequently guaranteeing the smooth movement of the connected rollers and the mesh transported on them. This support structure prevents the mesh from swaying or shifting during transport, laying the foundation for precise cutting later.

[0024] A controller, fixedly connected to the surface of the square mounting frame, provides centralized control of all components. When a cutting operation is required, the operator activates the second set of vertically mounted hydraulic cylinders via the controller. This second set of vertically mounted hydraulic cylinders is fixedly connected to the cutting mounting frame. Through extension and retraction, the hydraulic cylinders drive the cutting mounting frame and the cutting blade fixedly connected to its bottom vertically downwards. Because the hydraulic cylinders can precisely control the extension and retraction length, this precise control method allows for accurate control of the cutting blade's descent position according to the set cutting length, achieving precise positioning and cutting of the mesh.

[0025] Two L-shaped mounting brackets are fixedly connected to both sides of the cutting mounting frame, and these brackets engage with grooves on the left and right sides of the upper surface of the cutting seat, which is fixedly connected to the top of the fixed base perpendicular to the lower end of the cutting mounting frame. As the cutting blade descends to cut the mesh, the lower end of the L-shaped mounting bracket accurately engages in the groove. This engaging design positions and supports the cutting mounting frame in both horizontal and vertical directions. Horizontally, the grooves restrict the lateral movement of the L-shaped mounting brackets, ensuring that the cutting mounting frame does not shift left or right during cutting; vertically, the grooves provide stable support for the L-shaped mounting brackets, preventing them from wobbling due to cutting force or gravity. This positioning and stabilizing design further ensures the stability and precision of the cutting process, guaranteeing accurate dimensions and neat edges on the cut mesh.

[0026] In summary, the transport component, through power drive, the synergy between the rollers and the yarn, and a stable support structure, achieves adaptive transport of yarn of different sizes, greatly reducing manpower required for yarn transport. The cutting component, with precise power control and a robust positioning design, achieves accurate cutting of the yarn. The close cooperation of all components in the entire device ultimately achieves the goal of facilitating the adaptive transport and precise cutting of yarn of different sizes, effectively improving the efficiency and quality of acoustic yarn production and meeting diverse production needs.

[0027] 2. The connection and function of the cutting mounting base groove and the L-shaped mounting bracket in this utility model: The cutting mounting base is fixed to the top of the fixed base perpendicular to the lower end of the cutting mounting bracket. Its function is to provide a stable support foundation for the entire cutting positioning system, ensuring that the entire structure will not shift during the cutting process. The two grooves on the left and right sides of the upper surface of the cutting mounting base are key structures for achieving precise positioning and enhancing stability.

[0028] The two L-shaped mounting brackets fixedly connected to both sides of the cutting mounting bracket are designed to match the grooves. During the cutting process, when the cutting mounting bracket descends under the action of the second set of vertically mounted hydraulic cylinders, the lower ends of the L-shaped mounting brackets will accurately engage with the grooves on the upper surface of the cutting mounting base.

[0029] This interlocking design enables dual positioning of the cutting mount in both the vertical and horizontal directions. Vertically, the groove supports the lower end of the L-shaped mount, preventing excessive sinking or swaying due to gravity or cutting force during descent. Horizontally, the groove restricts the lateral movement of the L-shaped mount, ensuring a stable position during cutting.

[0030] This precise positioning method effectively improves the stability of the cutting process, avoiding cutting deviations caused by shaking or displacement of the cutting mounting frame, thus ensuring cutting accuracy and making the cut mesh edges neat and in line with production requirements.

[0031] In summary, the design of the groove on the upper surface of the cutting mounting base interlocking with the L-shaped mounting bracket provides stable positioning and support for the cutting mounting bracket during the cutting process of the auxiliary cutting device used in acoustic mesh production. This design effectively ensures cutting stability, enabling more precise cutting operations, reducing product quality problems caused by cutting instability, improving production efficiency and product quality, and meeting the requirements for cutting stability and precision in the acoustic mesh production process.

[0041] Example: Reference Figures 1 to 3 An auxiliary cutting device for acoustic mesh production includes a fixed base 1 and a transport component 2. The transport component 2 is fixedly connected to the top of the fixed base 1. The transport component 2 includes a protective mounting frame 201, which is mounted on the fixed base 1. A first set of vertically mounted hydraulic cylinders 202 is fixedly connected to the upper surface of the inner wall of the protective mounting frame 201. A square mounting frame 203 is fixedly connected to the lower end of the first set of vertically mounted hydraulic cylinders 202. Two sets of supporting rotating shafts 204 are rotatably connected to the left and right sides of the inner wall of the square mounting frame 203. Two lower mounting frames 205 are fixedly connected to the upper surface of the fixed base 1 perpendicular to the lower end of the square mounting frame 203. Two active rotating columns 206 are rotatably connected to the middle of the two lower mounting frames 205. Three sets of driven rotating columns 207 are fixedly connected to one side of the two active rotating columns 206 and inside the square mounting frame 203.

[0042] The driven rotating column 207 located in the middle of the square mounting bracket 203 is installed in the middle of the two sets of support rotating shafts 204, and two servo motors 208 are fixedly connected to one side of each of the two lower mounting brackets 205.

[0043] The output ends of the two servo motors 208 are rotatably connected to two sets of driving pulleys 209, and two sets of driven pulleys 210 are rotatably connected to one side of the driving pulleys 209. The two sets of driving pulleys 209 and the two sets of driven pulleys 210 are connected by a transmission belt 211.

[0044] Three sets of rollers 212 are rotatably connected to the surfaces of the two active rotating columns 206 and the three sets of driven rotating columns 207, and rubber anti-slip sleeves 213 are fixedly connected to the surfaces of the three sets of rollers 212.

[0045] In this embodiment, two servo motors 208 are fixedly connected to one side of the two lower mounting brackets 205, serving as the power source for the transport component 2. When the servo motors 208 start running, they are connected to the two sets of drive pulleys 209 via their output shafts, efficiently converting the electrical energy generated inside the motors into mechanical energy and transmitting it to the drive pulleys 209, causing them to rotate. This direct connection method achieves stable power output, providing initial power to the transport component 2 and ensuring the smooth operation of subsequent transmission links.

[0046] Two sets of driving pulleys 209 are connected to two sets of driven pulleys 210 on the same side via a transmission belt 211. The transmission belt 211 wraps around the driving pulleys 209 and driven pulleys 210. When the driving pulley 209 rotates, the friction between the belt and the pulley drives the transmission belt 211, causing the driven pulleys 210 to rotate synchronously with the driving pulley 209. This transmission method not only transmits power smoothly but also has a certain degree of elasticity and buffering, effectively reducing the impact caused by motor starting, stopping, or speed changes. Through this power transmission mechanism, the power of the servo motor 208 is accurately transmitted from the driving pulley 209 to the driven pulley 210, enabling the driving column 206 and driven column 207 to obtain rotational power, thereby providing continuous power support for the transportation of the mesh.

[0047] The driving rotary column 206 and the driven rotary column 207 are each connected to their corresponding pulleys. When the driven pulley 210 rotates, it drives the driving rotary column 206 and the driven rotary column 207 to rotate synchronously. This connection ensures that power can be smoothly transmitted from the pulleys to the rotary columns, and further transmits the rotational power to the roller 212, which is rotatably connected to the surface of the rotary column. Through this transmission connection, rotational power is provided to the roller 212, enabling it to rotate and transport the yarn.

[0048] Three sets of rollers 212 are rotatably connected to the surfaces of two driving rotating columns 206 and three sets of driven rotating columns 207, respectively. The rotation of the rotating columns drives the rollers 212 to rotate as well, making the rollers 212 the components that directly contact the yarn and perform the transport function. Rubber anti-slip sleeves 213 are fixedly connected to the surface of the rollers 212, making close contact with the yarn placed on them when the rollers 212 rotate. The surface of the rubber anti-slip sleeves 213 has a large frictional force, which converts the circular motion of the rollers 212 into the linear motion of the yarn, thereby driving the yarn forward on the device. The design of the rubber anti-slip sleeves 213 not only enhances the driving force on the yarn but also adaptively adjusts the frictional force according to the material, weight, and other characteristics of the yarn, ensuring that different types and sizes of yarn can be stably transported on the rollers 212, thus adapting to diverse yarn transport needs and ensuring that the yarn does not slip or deviate during transport.

[0049] The driven rotating column 207 in the middle of the square mounting bracket 203 is mounted between two sets of supporting rotating shafts 204. This mounting method provides a reliable support structure for the driven rotating column 207. The supporting rotating shafts 204 act as stable supports for the driven rotating column 207, enabling it to maintain a stable posture during high-speed rotation and preventing swaying or displacement due to centrifugal force or other external forces. This support structure ensures the stability of the driven rotating column 207's rotation, thereby guaranteeing the smooth operation of the connected roller 212 and the yarn transported on it, providing strong support for the stability of the yarn transport process.

[0050] Two lower mounting brackets 205 support the active rotating column 206, ensuring its stable position during rotation. The cooperation between the lower mounting brackets 205 and the active rotating column 206 allows the column to rotate on a fixed axis, providing a stable foundation for its rotation. Simultaneously, the lower mounting brackets 205 also provide mounting positions for other components such as the servo motor 208, organically integrating all parts of the transport assembly 2 into a stable overall structure. This integrated support and stability design ensures the overall structural stability of the transport assembly 2 during operation, enabling the mesh to be transported in a stable environment and providing favorable conditions for subsequent cutting processes.

[0051] refer to Figure 1 , Figure 4 and Figure 5 A controller 3 is fixedly connected to the surface of the square mounting bracket 203. A square hole 4 is opened on the upper surface of the square mounting bracket 203. A cutting component 5 is fixedly connected to the top of the vertical square hole 4. The cutting component 5 includes a second set of vertically mounted hydraulic cylinders 501. A cutting mounting bracket 502 is fixedly connected to the lower end of the second set of vertically mounted hydraulic cylinders 501.

[0052] A cutting blade 503 is fixedly connected to the bottom of the cutting mounting bracket 502, and two L-shaped mounting brackets 504 are fixedly connected to both sides of the cutting mounting bracket 502.

[0053] A cutting seat 505 is fixedly connected to the top of the fixed base 1 perpendicular to the lower end of the cutting mounting bracket 502. Two grooves 506 are opened on the left and right sides of the upper surface of the cutting seat 505.

[0054] In this embodiment, the controller 3, fixedly connected to the surface of the square mounting bracket 203, controls the initiation and operation of the cutting operation. When the operator issues a cutting command through the controller 3 according to the cutting requirements of the mesh, this command signal is accurately transmitted to the second set of vertically mounted hydraulic cylinders 501. Through the signal transmission connection between the controller 3 and the hydraulic cylinders, precise control of the cutting power source is achieved, enabling flexible initiation and adjustment of the cutting action according to actual production requirements.

[0055] The second set of vertically mounted hydraulic cylinders 501 are fixedly connected to the cutting mounting frame 502, and are the core power components for realizing the cutting action. Upon receiving a command from the controller 3, the hydraulic system inside the cylinder begins to operate, using changes in hydraulic oil pressure to drive the piston in a telescopic motion. The piston's telescopic motion drives the connected cutting mounting frame 502 to move vertically up and down. Utilizing the hydraulic cylinder's ability to precisely control the telescopic length and speed, the descent position and speed of the cutting mounting frame 502 and its bottom cutting blade 503 are accurately controlled according to the set cutting length and cutting process requirements, achieving precise positioning and cutting of the mesh, ensuring accurate cutting dimensions.

[0056] The cutting blade 503, fixedly connected to the bottom of the cutting mounting bracket 502, is the key tool directly performing the cutting task. The secure connection between the cutting blade 503 and the cutting mounting bracket 502 ensures that the cutting blade 503 can work stably with the movement of the cutting mounting bracket 502 during the cutting process, without loosening or displacement. When the cutting mounting bracket 502 descends, the sharp edge of the cutting blade 503 contacts the mesh and applies cutting force. Thanks to its excellent cutting performance, it achieves efficient cutting of the mesh, meeting the requirements of the mesh cutting process and ensuring cutting quality.

[0057] Two L-shaped mounting brackets 504 fixedly connected to both sides of the cutting mounting frame 502, together with the grooves 506 on the left and right sides of the upper surface of the cutting seat 505 fixedly connected to the top of the fixed base 1 perpendicular to the lower end of the cutting mounting frame 502, constitute the positioning and stabilization structure during the cutting process. When the cutting mounting frame 502 is lowered by the hydraulic cylinder, the lower end of the L-shaped mounting bracket 504 will accurately engage with the groove 506 on the cutting seat 505. In the horizontal direction, this engagement method restricts the L-shaped mounting bracket 504, preventing the cutting mounting frame 502 from moving laterally during the cutting process and ensuring the accuracy of the cutting direction; in the vertical direction, the groove 506 provides stable support for the L-shaped mounting bracket 504, preventing the cutting mounting frame 502 from swaying due to the reaction force of the cutting force or its own weight, and ensuring the stability of the cutting process. Through this precise positioning and stabilization design, the cutting accuracy is improved, ensuring that the edges of the cut mesh are neat and meet production standards.

[0058] Working principle: First, the mesh is passed through the top of the two lower mounting brackets 205 and the top of the cutting seat 505. This step determines the starting position for the subsequent transportation and cutting of the mesh. The purpose of preparing for the entire processing flow is to manually place the mesh.

[0059] Subsequently, the first set of vertically mounted hydraulic cylinders 202 is activated, and the thrust generated by the hydraulic cylinders drives the square mounting frame 203 to descend. Hydraulic power is used to achieve vertical displacement of the square mounting frame 203, adjusting its height to be closer to the mesh, facilitating subsequent control of the mesh transportation process.

[0060] Next, the controller 3 is activated to start the device. The control commands issued by the controller 3 enable the activation of all components of the device, so as to make the components work together and ensure that the device enters normal operation.

[0061] Then, the servo motors 208 located on one side of the two lower mounting brackets 205 start working, and the power output of the motors drives the drive pulley 209 on the feed port side of the protective mounting bracket 201 to rotate. With the driving capability of the servo motors 208, the rotation of the drive pulley 209 is realized, providing the initial power source for the entire transmission system.

[0062] The rotation of the drive pulley 209 drives the driven pulley 210 inside the lower mounting bracket 205 to rotate synchronously via the transmission belt 211. Relying on the transmission characteristics of the transmission belt 211, power is transmitted from the drive pulley 209 to the driven pulley 210, so that the driven pulley 210 follows the drive pulley 209 to rotate, thereby further transmitting the power.

[0063] The rotation of the driven pulley 210 drives the connected driving column 206 and driven column 207 to rotate. Through the connection between the columns, synchronous rotation of the columns is achieved, which in turn drives the roller 212 mounted on the surface of the lower mounting frame 205 to rotate. By utilizing the connection structure between the column and the roller 212, the purpose of driving the roller 212 to rotate is achieved, providing power for the transportation of the mesh.

[0064] The rubber anti-slip sleeve 213, fixedly connected to the surface of the roller 212, contacts the mesh. The friction between them drives the driven rotating column 207 and the supporting rotating shaft 204 in the middle of the square mounting frame 203 to rotate together. By utilizing the friction between the rubber anti-slip sleeve 213 and the mesh, the mesh moves stably forward during transportation, while simultaneously driving the relevant rotating column and shaft to rotate, further ensuring the stability and continuity of transportation.

[0065] Once the required cutting length of the mesh is determined, the second set of vertically mounted hydraulic cylinders 501 is activated. The thrust of the hydraulic cylinders drives the cutting mounting frame 502 and the cutting blade 503 to descend together. Hydraulic power is used to move the cutting components vertically, allowing the cutting blade 503 to pass through the square hole 4 on the upper surface of the square mounting frame 203, bringing the cutting blade 503 close to the mesh and preparing it for cutting.

[0066] As the cutting blade 503 descends, the lower ends of the L-shaped mounting brackets 504 on both sides of the cutting mounting bracket 502 engage with the grooves 506 on the left and right sides of the upper surface of the cutting seat 505. Through the cooperation between the L-shaped mounting brackets 504 and the grooves 506 of the cutting seat 505, precise positioning of the cutting mounting bracket 502 is achieved, ensuring the stability of the cutting process and preventing the mesh from becoming loose during cutting.

[0067] Finally, the cutting blade 503 cuts the mesh. After cutting, the cut mesh is pulled out from the other exit. Then, the user manually places the uncut mesh end onto the top of the lower mounting bracket 205 on the other side, and restarts the servo motor 208, driving the drive wheel, driven wheel, and roller 212 to rotate, repeating the above transport and cutting process for the next mesh cutting operation. The entire process, through the orderly and coordinated operation of each component, completes the continuous cutting of the acoustic mesh.

[0068] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
