Description

A speaker mesh slitting device for speaker production Technical Field

[0001] This utility model relates to the field of loudspeaker manufacturing, specifically to a loudspeaker mesh cutting device for loudspeaker manufacturing. Background Technology

[0002] In order to avoid affecting sound quality, modern audio equipment requires dustproof mesh to be installed on the outside of the speaker to prevent dust from entering the speaker and corroding the internal circuitry. In order to avoid affecting sound quality, the speaker mesh needs to be made as thin as possible. Thin speaker mesh is easily deformed under pressure, and the cut surface is prone to curling during speaker mesh cutting, which is not conducive to subsequent processing. Therefore, the demand for speaker mesh cutting equipment for speaker production is increasing.

[0003] Traditional speaker mesh cutting devices lack a mechanism for tensioning the speaker mesh, which easily leads to uneven cuts and further affects the quality of the mesh cutting. Therefore, a new technical solution is needed to address this issue. Summary of the Invention

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a speaker mesh cutting device for speaker production. This solves the technical problem that the current speaker mesh cutting device for speaker production lacks a mechanism for tensioning the speaker mesh, which easily causes uneven cutting ends during speaker mesh cutting and further affects the quality of speaker mesh cutting.

[0005] To achieve the objective of this utility model, the technical solution adopted by this utility model is as follows: A speaker mesh slitting device for speaker production is designed, comprising:

[0006] A conveying mechanism for conveying the speaker grille;

[0007] The slitting mechanism includes an electric hydraulic cylinder fixedly connected to the middle of the top of the gantry frame. A connecting plate is fixedly connected to the drive end of the electric hydraulic cylinder. Both ends of the connecting plate are provided with connecting grooves. Connecting rods are rotatably connected between the inner cavities of the two connecting grooves via bearings. Fixed rods are fixedly connected to the outer sides of the two connecting rods. An elastic smoothing roller is rotatably connected between the two fixed rods on the same side via bearings. The fixed rods on both sides are in an "eight" shape. A slitting blade is fixedly installed at the middle of the bottom end of the connecting plate. The length of the fixed rod is greater than the height of the slitting blade.

[0008] Preferably, the conveying mechanism includes two sets of drive rollers rotatably connected to the inner side of the frame via bearings, with two drive rollers in each set, and a conveyor belt disposed between the outer sides of the two drive rollers in each set.

[0009] Preferably, a torsion spring is sleeved on the outside of one side of the connecting rod, and the two ends of the torsion spring are fixedly connected to the inner wall of the connecting groove and the fixing rod, respectively.

[0010] Preferably, a support rod is fixedly connected to the inner wall of the connecting groove, and one outer end of the support rod movably abuts against the connecting rod.

[0011] Preferably, a mounting plate is fixedly connected to one side of the top of the frame, a groove is provided on the top of the mounting plate, a connecting shaft is provided in the groove, and an unwinding roller is fixedly connected to the outside of the connecting shaft.

[0012] Preferably, two fixed plates are fixedly connected to the frame between the mounting plate and the gantry. Each of the two fixed plates has a sliding groove, and a slider is slidably connected in each of the two sliding grooves. A pressure roller is rotatably connected between the two sliders through a bearing. A spring is fixedly connected to the top of the inner cavity of the sliding groove, and the bottom end of the spring is fixedly connected to the slider. A drive motor is fixedly connected to one of the outer ends of one of the sliders, and the drive end of the drive motor rotates through the slider and is fixedly connected to the pressure roller.

[0013] Preferably, a limiting groove is formed on both sides of the inner cavity of the slide groove, and a limiting block is slidably connected in both limiting grooves, with the end of the limiting block near the slider being fixedly connected to the slider.

[0014] Preferably, a base plate is fixedly connected to the frame between each group of drive rollers, and the surface of the base plate is in contact with the inner surface of the conveyor belt.

[0015] Preferably, an anvil is fixedly connected between the two sides of the frame between the two drive rollers, the surface of the anvil is on the same horizontal plane as the surface of the conveyor belt, and the two sides of the anvil are in contact with the surface of the conveyor belt.

[0016] Preferably, limiting discs are fixedly connected to the outside of the connecting shafts on both sides of the unwinding roller, and the two limiting discs are respectively movably abutting against the opposite ends of the two mounting plates.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. This utility model combines elastic smoothing rollers, connecting plates, electric hydraulic cylinders, connecting rods, fixing rods, and slitting structures. Two sets of symmetrically arranged "eight"-shaped elastic smoothing rollers first contact the surface of the speaker mesh, and then perform bidirectional flattening of the speaker mesh during continuous downward pressure. At the same time, the dynamic static friction coupling principle is used to achieve bidirectional tension adaptive adjustment of the speaker mesh, effectively eliminating processing stress deformation. After the tension of the speaker mesh reaches the preset parameters, the slitting blade contacts the speaker mesh to cut it, and then automatically smooths and tightens the cut speaker mesh, thereby improving the flatness of the cut end face of the speaker mesh and further improving the quality of speaker mesh cutting.

[0019] 2. This utility model utilizes a torsion spring. When the electric hydraulic cylinder pushes the elastic smoothing roller to perform bidirectional flattening of the trumpet mesh, the torsion spring simultaneously enters an elastic pre-tension state, precisely storing the mechanical potential energy required for the operation. After the slitting process is completed, the electric hydraulic cylinder pulls the elastic smoothing roller to reset. During this process, the preloaded torsion spring releases the stored energy, and the reset of the elastic smoothing roller is achieved through the torque transmission system. This not only ensures that the processing unit quickly returns to its initial work position, but also, through the dynamic stress compensation function of the torsion spring, ensures that the elastic smoothing roller always maintains optimal working tension. This provides a constant and stable flattening force and radial tension force for each trumpet mesh slitting unit in continuous production, effectively ensuring the consistency of batch-processed products.

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0026] Example 1: A speaker mesh slitting device for speaker production, as shown in Figures 1 to 4, includes: a conveying mechanism for conveying speaker mesh, the conveying mechanism including two sets of drive rollers 12 rotatably connected to the inner side of a frame 1 via bearings, each set of drive rollers 12 having two rollers, and a conveyor belt 11 disposed between the outer sides of the two drive rollers 12 in each set, the drive rollers 12 being driven to rotate by a motor; and a slitting mechanism, the slitting mechanism including an electric hydraulic cylinder 41 fixedly connected to the middle of the top end of a gantry frame 4, the electric hydraulic cylinder 41 being driven to rotate by a motor. A connecting plate 42 is fixedly connected to the moving end. Both ends of the connecting plate 42 are provided with connecting grooves 43. Connecting rods 44 are rotatably connected between the two inner cavities of the two connecting grooves 43 through bearings. Fixing rods 45 are fixedly connected to the outer sides of the two connecting rods 44. An elastic smoothing roller 46 is rotatably connected between the two fixing rods 45 on the same side through bearings. The fixing rods 45 on both sides are in an "eight" shape. A slitting blade 49 is fixedly installed in the middle of the bottom end of the connecting plate 42. The length of the fixing rod 45 is greater than the height of the slitting blade 49.

[0027] During operation, the motor drives the drive roller 12 to rotate, which in turn drives the conveyor belt 11 to rotate. After the speaker mesh to be cut is transported to the area below the slitting blade 49, the electric hydraulic cylinder 41 is activated to push the connecting plate 42 downward. As a result, the two sets of symmetrically arranged "eight"-shaped elastic smoothing rollers 46 first come into contact with the surface of the speaker mesh. During the continuous downward pressure, the speaker mesh is flattened in both directions. At the same time, the dynamic static friction coupling principle is used to achieve bidirectional tension adaptive adjustment of the speaker mesh, effectively eliminating processing stress deformation. After the tension of the speaker mesh reaches the preset parameters, the slitting blade 49 contacts the speaker mesh to cut it. The cut speaker mesh can be automatically smoothed and tightened, thereby improving the flatness of the cut end face of the speaker mesh and further improving the quality of speaker mesh cutting.

[0028] Specifically, referring to Figure 2, a torsion spring 47 is sleeved on the outside of one side of the connecting rod 44. The two ends of the torsion spring 47 are fixedly connected to the inner wall of the connecting groove 43 and the fixing rod 45, respectively. When the electric hydraulic cylinder 41 pushes the elastic smoothing roller 46 to perform bidirectional flattening operation on the trumpet mesh, the torsion spring 47 simultaneously enters the elastic pre-tension state, accurately storing the mechanical potential energy required for the operation. After the slitting process is completed, the electric hydraulic cylinder 41 pulls the elastic smoothing roller 46 to reset. During this process, the preloaded torsion spring 47 releases the stored energy, and the reset of the elastic smoothing roller 46 is achieved through the torque transmission system. This not only ensures that the processing unit quickly returns to the initial work position preparation state, but also, through the dynamic stress compensation function of the torsion spring 47, ensures that the elastic smoothing roller 46 always maintains the best working tension, providing a constant and stable flattening force and radial tension force for each trumpet mesh slitting unit in continuous production, effectively ensuring the consistency of batch processed products.

[0029] Furthermore, referring to Figure 2, a support rod 48 is fixedly connected to the inner wall of the connecting groove 43. One outer end of the support rod 48 is movably abutted against the connecting rod 44. The support rod 48 supports the connecting rod 44, ensuring that the elastic smoothing rollers 46 on both sides are always arranged in a figure-eight shape. This further ensures that the elastic smoothing rollers 46 continuously press down and perform bidirectional flattening and tightening of the speaker mesh.

[0030] It is worth noting that, referring to Figure 1, a mounting plate 2 is fixedly connected to one side of the top of the frame 1. A groove 21 is provided on the top of the mounting plate 2, and a connecting shaft 22 is provided in the groove 21. An unwinding roller 24 is fixedly connected to the outside of the connecting shaft 22. Limiting discs 23 are fixedly connected to the outside of the connecting shaft 22 on both sides of the unwinding roller 24. The two limiting discs 23 are respectively movably abutting against the opposite ends of the two mounting plates 2. The groove 21 facilitates the placement of the connecting shaft 22, and facilitates the rotation, unwinding, and cutting of the trumpet mesh wound on the unwinding roller 24. The limiting discs 23 limit the connecting shaft 22 in the groove 21, thereby preventing the unwinding roller 24 from rotating and causing the connecting shaft 22 to disengage from the groove 21, which would cause the unwinding roller 24 to fall off.

[0031] It is worth noting that, referring to Figures 1 and 3, two fixed plates 31 are fixedly connected to the frame 1 between the mounting plate 2 and the gantry 4. Each of the two fixed plates 31 has a sliding groove 32, and a slider 33 is slidably connected in each of the two sliding grooves 32. A pressure roller 3 is rotatably connected between the two sliders 33 through a bearing. A spring 34 is fixedly connected to the top of the inner cavity of the sliding groove 32. The bottom end of the spring 34 is fixedly connected to the slider 33. A drive motor 35 is fixedly connected to one of the outer ends of one of the sliders 33. The drive end of the drive motor 35 rotates through the slider 33 and is fixedly connected to the pressure roller 3. When the speaker mesh is being cut, the pressure roller 3 is placed above the speaker mesh conveyed by the conveyor belt 11. The elastic force of the spring 34 pushes the pressure roller 3 to make stable contact with the speaker mesh on the conveyor belt 11. Thus, when the speaker mesh is being moved and cut by the conveyor belt 11, the drive motor 35 drives the pressure roller 3 to rotate, thereby the friction between the pressure roller 3 and the speaker mesh assists in conveying the speaker mesh on the conveyor belt 11.

[0032] It is worth noting that, as shown in Figure 3, limiting grooves 36 are provided on both sides of the inner cavity of the slide groove 32. Limiting blocks 37 are slidably connected in both limiting grooves 36, and the end of the limiting block 37 near the slider 33 is fixedly connected to the slider 33. The limiting block 37 guides the slider 33 to move within the limiting groove 36, thereby preventing the slider 33 from detaching from the slide groove 32 and affecting the normal use of the pressure roller 3.

[0033] It is worth mentioning that, referring to Figure 4, a base plate 5 is fixedly connected to the frame 1 between each group of drive rollers 12. The surface of the base plate 5 is in contact with the inner surface of the conveyor belt 11. By setting the base plate 5, when the elastic smoothing roller 46 flattens and tightens the trumpet net, the base plate 5 supports the conveyor belt 11, so as to prevent the conveyor belt 11 from deforming and affecting the flattening and tightening effect of the trumpet net.

[0034] It is worth mentioning that, referring to Figure 4, an anvil 6 is fixedly connected between the two sides of the frame 1 between the two drive rollers 12. The surface of the anvil 6 is on the same horizontal plane as the surface of the conveyor belt 11. The two sides of the anvil 6 move against the surface of the conveyor belt 11. The anvil 6 supports the horn mesh at the cutting position, further ensuring that the slitting blade 49 can complete the cutting of the horn mesh when it comes into contact with the anvil 6.

Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.
