Description

Technical Field

[0001] This utility model relates to the field of diaphragm slitting machine technology, and more specifically, to a diaphragm slitting machine with a flattening function. Background Technology

[0002] In electroacoustic devices, such as loudspeakers, receivers, and headphones, the diaphragm is a key component that converts electrical signals into mechanical vibrations and radiates sound waves. Its physical properties, such as flatness, thickness uniformity, and surface tension consistency, directly affect the acoustic performance of the final product, such as the smoothness of the frequency response curve, distortion rate, and sensitivity.

[0003] Diaphragms are typically made of polymers or metal / composite materials and require precision machining to form thin sheet structures of specific shapes and sizes. A diaphragm slitting machine is a crucial downstream process in diaphragm production, its function being to cut large rolls of raw substrate, several meters wide and hundreds of meters long, into multiple independent diaphragm units according to target specifications, providing the base material for subsequent die-cutting, lamination, and other processes. According to authorization announcement number CN220593312U, an automatic diaphragm cutting machine is disclosed, including a worktable. A turntable for fixing the diaphragm is rotatably mounted on the top of the worktable. An inner ring cutting mechanism and an outer ring cutting mechanism are mounted on the top of the worktable. One end of each mechanism is fixed to the top surface of the worktable, and the other end extends to the inner and outer ring edges of the turntable. Each mechanism is movably equipped with a first blade and a second blade for cutting the diaphragm. A first motor that drives the turntable to rotate is mounted at the bottom of the worktable, and a pressing mechanism that presses the upper plate tightly against the lower plate is mounted on the top of the worktable. The inner and outer ring cutting mechanisms have first and second blades pointing towards the inner and outer ring edges of the turntable, respectively. The rotation of the first motor drives the turntable to rotate, causing the first and second blades to automatically cut the diaphragm without the need for personnel to handle the blades, thus reducing manual labor intensity. At the same time, the mechanically fixed blades are more stable.

[0004] Currently, when slitting diaphragm substrates with a large width, the diaphragm substrates are quite long during the slitting process. Due to the influence of the elastic coefficient of different diaphragm materials, if the tension of the transmission components is constant during slitting, some substrates with greater elasticity may become skewed and deformed during transport because they are not flattened with the assistance of a tensioning structure.

A piston rod two for driving is provided inside the cylinder two, and a support frame two is fixedly installed at the end of the piston rod two.

[0008] Preferably, both sides of the second support frame are fixed with bearing seats, and the same central shaft is rotatably installed inside the two bearing seats.

[0009] Preferably, a guide roller is fixedly sleeved on the surface of the central shaft, and the surface of the guide roller is provided with a plurality of cutting grooves, which are equidistantly distributed along the surface of the guide roller.

[0010] Preferably, the upper end of the positioning frame is fixed with bushings on both sides, and the two bushings distributed on both sides are rotatably connected to the same shaft.

[0011] Preferably, a plurality of cutting discs are fixedly distributed on the surface of the shaft two, and any one of the cutting discs is fitted with a cutting groove at a corresponding position. A motor two is provided at the outer end of the shaft two, and the outer ring wall of the motor two is fixed to the surface of the positioning frame through a bracket. A rotating shaft two for driving is provided inside the motor two, and the end of the rotating shaft two is connected to the shaft two for transmission through a coupling.

[0012] Preferably, a connecting plate is fixedly installed on the side of the base away from the positioning frame.

A vacuum adsorption stage is fixedly installed at the end of the piston rod three. The vacuum adsorption stage has an inner cavity. An adsorption port penetrating through the inner cavity is opened at the upper end of the vacuum adsorption stage. The adsorption port is connected to the inner cavity.

[0013] Preferably, a side plate is fixedly installed on the lower end of one side of the vacuum adsorption stage, and a vacuum pump is fixedly installed on the surface of the side plate by a bracket.

[0014] The targeted solution provided by this utility model has the following beneficial effects: 1. This utility model utilizes symmetrically arranged cylinders to drive the support frame for precise up-and-down movement, thereby flexibly adjusting the distance between the two conveying rollers. This adjustment mechanism ensures that the diaphragm substrate is always subjected to appropriate clamping force during the conveying process, which not only effectively prevents the material from loosening or wrinkling, but also assists in flattening the surface through the rolling friction of the rollers. At the same time, the motor drives the conveying rollers to rotate actively, ensuring that the substrate is conveyed forward at a uniform speed, avoiding slippage or deviation. 2. The guide roller of this utility model has equally spaced cutting grooves on its surface, and its height is adjusted by a cylinder so that the diaphragm substrate can be closely attached to the surface of the guide roller to form a solid support area. At the same time, multiple cutting discs on the shaft are precisely matched with the corresponding cutting grooves and rotate at high speed under the drive of the motor to realize the continuous slitting of the diaphragm substrate. 3. The vacuum adsorption table of this utility model has an inner cavity connected to the adsorption port, and a vacuum pump generates negative pressure to firmly adsorb the diaphragm substrate onto the table surface during the transport process, effectively suppressing its warping or sliding. The cylinder drives the vacuum adsorption table to make fine adjustments to its height, so that it can quickly approach the substrate or maintain the optimal adsorption distance in the initial adsorption stage, adapting to materials with different thicknesses or tension requirements.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Example

[0019] Reference Figures 1-4 This utility model provides a technical solution: a diaphragm slitting machine with a flattening function, including a base 1, a rectangular frame 10 fixedly installed at the upper center of the base 1, and cylinders 11 fixedly installed at both the upper and lower ends of the inner wall of the rectangular frame 10. A piston rod for extension and retraction is provided inside the cylinder 11, and a support frame 12 is fixedly installed at the end of the piston rod. Bushings 13 are fixedly installed through both sides of the support frame 12. A shaft 14 is rotatably installed inside the two bushings 13 distributed along both sides. By extending and retracting the piston rod of the cylinder 11, the two support frames 12 can be driven to move up and down in a matching manner.

[0020] A conveyor roller 15 is fixedly sleeved on the surface of shaft 14. A motor 16 is installed at the outer end of shaft 14. The outer ring wall of motor 16 is fixed to the surface of support frame 12 by bracket. A drive shaft is installed inside motor 16, and the end of the drive shaft is connected to shaft 14 for transmission via coupling. A rectangular hole 17 is opened on one side of rectangular frame 10, and motor 16 is installed inside the rectangular hole 17. The two support frames 12 can be adjusted to adjust the distance between the two conveyor rollers 15. When the diaphragm substrate is conveyed, the diaphragm substrate can be pressed and flattened at the same time. The motor 16 is connected to the power supply to make the drive shaft rotate, so that shaft 14 can drive conveyor roller 15 to roll, thereby achieving stable conveying of diaphragm substrate. With the continuous adjustment of piston rod of cylinder 11, the height of diaphragm substrate at the position of conveyor roller 15 can be adjusted, thus having an auxiliary tensioning effect.

[0021] A positioning frame 20 is fixedly installed on one side of the upper end of the base 1. A cylinder 21 is fixedly installed on the lower end of the inner wall of the positioning frame 20. A piston rod 2 for driving is provided inside the cylinder 21, and a support frame 22 is fixedly installed at the end of the piston rod 2. The piston rod 2 of the cylinder 21 can extend and retract to adjust the height of the support frame 22.

[0022] Among them, the two sides of the support frame 22 are fixed with bearing seats 23, and the same central shaft 24 is rotatably installed inside the two bearing seats 23. The central shaft 24 can rotate stably based on the bearing seats 23.

[0023] Among them, a guide roller 25 is fixedly sleeved on the surface of the central shaft 24. The surface of the guide roller 25 is provided with several cutting grooves 26. The cutting grooves 26 are evenly distributed along the surface of the guide roller 25. When the diaphragm substrate is continuously conveyed and slit, the guide roller 25 plays a transitional bearing role, so that the diaphragm substrate has a stable support area when it is slit. By extending and retracting the piston rod of the second cylinder 21, the guide roller 25 can drive the diaphragm substrate to contact the cutting disc 203, so as to achieve stable contact slit slit.

[0024] Among them, the upper end of the positioning frame 20 is fixed with bushing 201 on both sides, and the two bushings 201 distributed on both sides are rotatably connected to the same shaft 202. The shaft 202 can rotate stably based on the bushing 201.

[0025] The shaft 202 has several cutting discs 203 fixedly distributed on its surface. Each cutting disc 203 is fitted with a corresponding cutting groove 26. A motor 204 is installed at the outer end of the shaft 202. The outer ring wall of the motor 204 is fixed to the surface of the positioning frame 20 through a bracket. The motor 204 has a rotating shaft 2 for driving inside. The end of the rotating shaft 2 is connected to the shaft 202 through a coupling. When the cutting disc 203 needs to rotate, the power supply of the motor 204 is turned on, so that the rotating shaft 2 can rotate and the shaft 202 can rotate synchronously, thereby achieving stable rotation of the cutting disc 203.

[0026] A connecting plate 30 is fixedly installed on the side of the base 1 away from the positioning frame 20. Cylinders 31 are symmetrically fixed on the top of the connecting plate 30. A piston rod 3 for extension and retraction is provided inside the cylinder 31, and a vacuum adsorption table 32 is fixedly installed at the end of the piston rod 3. The vacuum adsorption table 32 has an inner cavity. An adsorption port 33 is opened at the upper end of the vacuum adsorption table 32, which is connected to the inner cavity. The extension and retraction of the piston rod 3 of the cylinder 31 can realize the height adjustment of the vacuum adsorption table 32, so that when the diaphragm substrate is transported, the vacuum adsorption table 32 can first adhere to the diaphragm substrate or reach the specified adsorption distance in the initial adsorption stage.

[0027] A side plate 34 is fixedly installed on the lower side of one side of the vacuum adsorption table 32. A vacuum pump 35 is fixedly installed on the surface of the side plate 34 by a bracket. A vacuum pipe 36 is fixedly installed through one side of the vacuum adsorption table 32. One end of the vacuum pipe 36 is connected to the inner cavity. The end of the vacuum pipe 36 away from the vacuum adsorption table 32 is connected to the air inlet flange of the vacuum pump 35. When it is necessary to adsorb the diaphragm substrate, the power supply of the vacuum pump 35 is turned on, so that the vacuum pump 35 produces a vacuuming effect, so that the diaphragm substrate passing through the vacuum adsorption table 32 can be attached to the top of the vacuum adsorption table 32 through the adsorption port 33. At the same time, when the diaphragm substrate is continuously adsorbed, it will not affect the conveying of the diaphragm substrate, but only has the effect of adsorption and auxiliary flattening. Furthermore, when the diaphragm substrate is stably slidably attached to the vacuum adsorption table 32, the height of the vacuum adsorption table 32 can be adjusted by extending and retracting the piston rod of the cylinder 31, so as to achieve auxiliary tensioning of the conveying of the diaphragm substrate.

[0028] In practical implementation: This scheme uses a cylinder 11 installed inside the rectangular frame 10 at the upper end of the base 1 to drive the piston rod to extend and retract, thereby driving the support frame 12 to move up and down. Bushings 13 are fixed on both sides of the support frame 12, and a shaft 14 is rotatably installed inside the bushings 13. A conveyor roller 15 is sleeved on the surface of the shaft 14 and is connected to the shaft 14 via the rotating shaft of the motor 16, enabling the conveyor roller 15 to roll. During the conveying of the diaphragm substrate, the two support frames 12 can adjust the distance between the two conveyor rollers 15 to press and flatten the diaphragm substrate. Simultaneously, after the motor 16 is powered on, the rotating shaft rotates, driving the shaft 14 and the conveyor roller 15 to roll, achieving stable conveying. The piston rod of the cylinder 11 continuously adjusts its height, causing the height of the diaphragm substrate at the position of the conveyor roller 15 to change, assisting in tensioning the diaphragm substrate and ensuring no loosening or wrinkling during conveying. A rectangular hole 17 on one side of the rectangular frame 10 allows the motor 16 to pass through, ensuring structural compactness and freedom of movement.

[0029] The slitting function is achieved by the cylinder 21 at the lower end of the positioning frame 20 driving the piston rod 2 to extend and retract, adjusting the height of the support frame 22. Support frame 22 has fixed bearing seats 23 on both sides, with a central shaft 24 rotatably mounted inside the bearing seats 23. Guide rollers 25 are sleeved on the surface of the central shaft 24, and cutting grooves 26 are equidistantly formed on the surface of the guide rollers 25. The upper end of the positioning frame 20 has fixed bushings 201 on both sides, with shaft rods 202 rotatably mounted inside the bushings 201. Cutting discs 203 are fixedly distributed on the surface of shaft rods 202. The cutting discs 203 are aligned with the support frame 20. When the cutting groove 26 is engaged, the rotating shaft of motor 204 is driven by shaft 202 through a coupling. After the power is turned on, the rotating shaft rotates, driving shaft 202 and cutting disc 203 to rotate. When the diaphragm substrate is being conveyed, cylinder 21 adjusts the height of guide roller 25 so that the diaphragm substrate contacts the cutting disc 203. Guide roller 25 provides a stable support area. During the rotation, the cutting disc 203 slits the diaphragm substrate. The cutting groove 26 ensures cutting accuracy and material integrity, achieving efficient slitting operation.

[0030] The flattening and adsorption functions are achieved by extending and retracting the piston rod of cylinder 31 symmetrically distributed on the connecting plate 30, which adjusts the height of the vacuum adsorption table 32. The vacuum adsorption table 32 has an internal cavity with an adsorption port 33 at the top that communicates with the cavity. The side plate 34 is fixed with a vacuum pump 35 by a bracket. One end of the vacuum pipe 36 is connected to the cavity of the vacuum adsorption table 32, and the other end is connected to the air inlet of the vacuum pump 35. During the transport of the diaphragm substrate, the vacuum pump 35 is powered on to generate a vacuuming effect, which allows the diaphragm substrate to adhere to the upper surface of the vacuum adsorption table 32 through the adsorption port 33, thus achieving adsorption and flattening. The height adjustment of the piston rod of cylinder 31 can change the position of the vacuum adsorption table 32, so that the diaphragm substrate can quickly adhere or reach a specified distance in the initial adsorption stage, assisting in the tensioning and transport process. The continuous adsorption of the vacuum adsorption table 32 does not affect the sliding of the diaphragm substrate, but only provides stable support and flattening, ensuring that the material is not deformed or shifted before cutting.

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.
