Description

Technical Field

[0001] The present invention relates to an earphone device, in particular to a stamping device with a linked noise reduction earphone applied in the technical field of stamping equipment. Background Art

[0002] Stamping is a forming method that relies on a press and a die to apply external force to plates, strips, pipes and profiles to cause plastic deformation or separation, thereby obtaining a workpiece of the desired shape and size. There are different classification methods for stamping processing according to different process conditions. However, during the stamping process, the workshop will emit huge noise interference. There are two sources of noise. One is the mechanical noise generated by extrusion and friction when the punching machine is running, and the other is the vibration noise generated when the punching machine is running. People working in a workshop with high noise intensity for a long time will seriously damage their hearing. Therefore, it is necessary to reduce the noise to ensure the physical and mental health of workers.

[0003] The specification of Chinese patent CN206612266U discloses a mining safety helmet, which includes a helmet body and a safety belt. External ear covers are provided on both sides of the helmet body, and an inner ear component is provided inside the external ear cover. The inner ear component includes an inner ear plug that slides along the central axis of the external ear cover and fits in the external ear cover, and a pushing member that is rotatably connected to the external ear cover and applies force to the inner ear plug to realize the movement of the inner ear plug. Combined with the external ear cover and the inner ear plug, it can achieve the effect of double sound insulation and noise reduction.

[0004] The specification of Chinese patent CN104413979A discloses a noise-proof safety helmet with earplugs, which includes a helmet body, a safety belt, rivets and earplugs. The safety belt is fixed to the lower part of the helmet body by rivets, and the earplugs are installed on the inner walls on the left and right sides of the helmet body by rivets. The earplugs can prevent noise from damaging the ears.

[0005] A mining helmet uses earplugs to expand and fill the ear canal to reduce noise. A noise-proof helmet with earplugs reduces noise by filling the ear canal with soft rubber earplugs. However, it still has certain limitations. It still requires manual twisting operation, simple earplugs cannot achieve deep noise reduction, and the noise reduction cannot be flexibly adjusted according to the noise level. Summary of the invention

[0006] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is to automatically and deeply reduce the noise in the stamping operation and flexibly adjust the noise reduction according to the noise level.

[0007] In order to solve the above problems, the present invention provides a stamping device with a linked noise-reducing headset, comprising a headset, an ear handle, an ear pad and a stamping machine. An ear cavity is arranged between the ear handle and the ear pad, a noise control component is installed inside the ear cavity, the noise control component comprises a guide frame fixedly connected between the ear handle and the ear pad, a moving magnetic block is slidably connected to the guide frame, a septum is fixedly connected to one side of the moving magnetic block, an electromagnetic block is fixedly connected to the other end of the septum, an embedding rod is fixedly connected to the middle of the moving magnetic block, the embedding rod passes through the septum and one end of the electromagnetic block is fixedly connected to a nipple plug, and an extension sleeve is fixedly connected to the end of the electromagnetic block away from the septum. A noise adjusting component is arranged on the noise control component, the noise adjusting component comprises a micro motor, the micro motor is fixedly connected to the upper surface of the guide frame, a guide rope is wound around the micro motor, the other end of the guide rope is fixedly connected to a control plate, the control plate is rotatably connected to the guide frame, and a control groove is opened on the guide frame, and the diameter of the control groove is the same as that of the control plate.

[0008] Preferably, the stretch sleeve is hollowed out, and a plurality of shaping strips are arranged on the inner wall of the stretch sleeve. The shaping strips are annular strip structures, and the plurality of shaping strips are all made of rubber material.

[0009] Preferably, the electromagnetic block is an annular structure, and the electromagnetic block and the moving magnetic block are located on the same center line.

[0010] Preferably, the sac is made of rubber material, and the interior of the sac is filled with gas or liquid, such as nitrogen or water.

[0011] Preferably, the nipple plug is made of medical highly transparent silicone gel and has a soft jelly texture.

[0012] Preferably, the earphone is provided with a noise monitor, a noise collection module, a signal sending module, a 5G communication module, a noise discrimination module and a GPS positioning module. The noise monitor is a CPU data processing chip. The noise collection module is provided with a signal conversion module. The signal conversion module converts the collected noise into an electrical signal. The signal sending module sends the electrical signal to the terminal. The 5G communication module is used to transmit the electrical signal to the control room of the stamping machine in real time.

[0013] Preferably, an indication module is provided in the noise monitor, and an LED status light electrically connected to the indication module is provided on the surface of the earphone, and the LED status light is used to indicate the noise index level.

[0014] Preferably, a wireless charging module is provided in the earphone, and the wireless charging module is a 2000mA wirelessly rechargeable lithium battery.

[0015] Preferably, the terminal includes a stamping machine control room, in which a signal receiving module is provided for receiving the noise electrical signal sent by the signal sending module in the earphone, and the stamping machine control room includes a display module, a prompt module, a coordinate module, an alarm module and a monitoring module.

[0016] Preferably, the electromagnetic block and the micro motor are both electrically connected to a controller.

[0017] In summary, this solution has the following beneficial effects: 1. The energized electromagnetic block attracts the moving magnetic block to move and squeeze the septum, so that the nipple plug is tightly pressed against the extension sleeve. The nipple plug expands and bulges fully filling the inside of the ear canal, which has the effect of sound insulation and noise reduction. The nipple plug is medical silicone gel with a very soft texture. It can fit the ear canal completely, which is safer and more comfortable.

[0018] 2. The stretch sleeve is a hollow high-elastic mesh with multiple tough shaping strips inside, which can effectively prevent the stretch sleeve from becoming soft and collapse, ensuring that the nipple plug can be more accurately and completely inserted into the stretch sleeve. Both the stretch sleeve and the shaping strips are made of flexible materials, do not damage the ear canal, are highly breathable, and are safe and hygienic.

[0019] 3. According to the noise intensity, the retracting and releasing states of the left and right motors are controlled so that the control panel can flip freely in the control slot, thereby automatically blocking the moving magnetic block or releasing the lock of the moving magnetic block, triggering different sound insulation and noise reduction operating states for different noise levels, with high flexibility, full automation and high efficiency.

[0020] 4. The noise discrimination module divides the noise level into three levels: low, medium and high, thereby triggering and switching different operating states of the noise control components. The indication module will also trigger the corresponding LED status light to light up, so that when adjacent personnel communicate, they only need to observe whether the LED status light of the headset is on to determine whether the headset is in the noise reduction state, so as to carry out normal language communication without removing the headset.

DETAILED DESCRIPTION

[0023] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings. Example

[0024] Figure 1-Figure 12 FIG. 1 shows a stamping device with a linked noise reduction headset, comprising a headset 1, an ear handle 2, an ear pad 3 and a stamping machine, an ear cavity 4 is provided between the ear handle 2 and the ear pad 3, a noise control component 5 is installed inside the ear cavity 4, the noise control component 5 comprises a guide frame 501 fixedly connected between the ear handle 2 and the ear pad 3, a moving magnetic block 502 is slidably connected to the guide frame 501, a spacer 503 is fixedly connected to one side of the moving magnetic block 502, an electromagnetic block 505 is fixedly connected to the other end of the spacer 503, an embedded rod 504 is fixedly connected to the middle of the moving magnetic block 502, and the embedded rod 504 penetrates the spacer 503. One end of the capsule 503 and the electromagnetic block 505 is fixedly connected with a nipple plug 506, and one end of the electromagnetic block 505 away from the septum 503 is fixedly connected with a stretching sleeve 507. The noise control component 5 is provided with a noise adjustment component 6, and the noise adjustment component 6 includes a micro motor 601, and the micro motor 601 is fixedly connected to the upper surface of the guide frame 501, and the micro motor 601 is wound with a guide rope 602, and the other end of the guide rope 602 is fixedly connected with a control plate 603, and the control plate 603 is rotatably connected to the guide frame 501, and a control groove is opened on the guide frame 501, and the diameter of the control groove is the same as that of the control plate 603; The stretch sleeve 507 is hollowed out, and a plurality of shaping strips 508 are arranged on the inner wall of the stretch sleeve 507. The shaping strips 508 are annular strip structures, and the plurality of shaping strips 508 are made of rubber material. The electromagnetic block 505 is annular in structure, and the electromagnetic block 505 and the moving magnetic block 502 are located on the same center line. The septum 503 is made of rubber material, and the interior of the septum 503 is filled with gas or liquid, such as nitrogen or water. The nipple plug 506 is a medical highly transparent silicone gel, and the nipple plug 506 has a soft jelly texture.

[0025] like Fig. 9 As shown in FIG. 1 , when all the stamping machines start to operate and are in a high noise state, the electromagnetic block 505 electrically connected to the controller is powered on, and the moving magnetic block 502 is attracted to move to the leftmost end, greatly compressing the septum 503, pushing the nipple plug 506 to completely press the extension sleeve 507, so that the nipple plug 506 is in a squeezed and raised state, fully filling the ear canal and completely isolating the noise. At the same time, Fig.11 As shown, the micro motor 601 is started to work, and the two micro motors 601 simultaneously perform the line-reeling motion, thereby pulling the two control plates 603 at the bottom of the lead ropes 602 at both ends to flip to a horizontal state together, thereby releasing the interception and blocking of the moving magnetic block 502; like Figure 8 As shown, when multiple sets of punching machines start to work and are in a medium noise state, the electromagnetic block 505 electrically connected to the controller is powered on, and the moving magnetic block 502 is attracted to move to the left end, thereby compressing the septum 503 and pushing the nipple plug 506 to press into the extension sleeve 507, so that the nipple plug 506 is in a squeezed and slightly raised state, filling the ear canal and isolating the noise. At the same time, Fig.10 As shown, the micro motor 601 is started to work, and the right micro motor 601 performs a line-reeling movement, thereby pulling the right control plate 603 at the bottom of the right guide rope 602 to flip to a horizontal state, and releasing the interception and blocking of the moving magnetic block 502. The left micro motor 601 performs a line-releasing movement, thereby loosening the left control plate 603 at the bottom of the left guide rope 602. The left control plate 603 loses traction and presents a vertical state due to its own weight, thereby blocking the further movement of the moving magnetic block 502, and controlling the compression degree of the septum 503 and the extrusion state of the nipple plug 506; like Figure 3 and 4 As shown, when the machine tool stops working or is in a low noise state, the electromagnetic block 505 is powered off, the spacer 503 pushes the moving magnetic block 502 to slide to the rightmost position, and the nipple plug 506 is set in the extension sleeve 507. At the same time, Figure 7 As shown, the micro motor 601 is started, and the two micro motors 601 simultaneously release the wires, so that the two control plates 603 at the bottom of the guide ropes 602 at both ends are restored to the initial state together, intercepting and blocking the moving magnetic block 502, and relying on the earphone 1 and the ear pad 2 themselves to reduce noise and sound insulation.

[0026] When personnel need to communicate, they can communicate without taking off the earphones 1. Figure 8 As shown, if the current working environment is of medium noise, it is only necessary to cut off the power supply state of the electromagnetic block 505, so that the moving magnet 502 slides to the rightmost end, pull the nipple plug 506 to reset, and release the filling state of the ear canal. At this time, the personnel can communicate normally. Example

[0027] Figure 13-14 As shown, the headset 1 is provided with a noise monitor, a noise collection module, a signal sending module, a 5G communication module, a noise discrimination module and a GPS positioning module. The noise monitor is a CPU data processing chip. The noise collection module is provided with a signal conversion module. The signal conversion module converts the collected noise into an electrical signal. The signal sending module sends the electrical signal to the terminal. The 5G communication module is used to transmit the electrical signal to the control room of the stamping machine in real time. The noise monitor is provided with an indication module, and the surface of the earphone 1 is provided with an LED status light electrically connected to the indication module, and the LED status light is used to indicate the noise index level. The earphone 1 is provided with a wireless charging module, and the wireless charging module is a 2000mA wirelessly rechargeable lithium battery; The terminal includes a stamping machine control room, in which a signal receiving module is provided for receiving the noise electrical signal sent by the signal sending module in the earphone 1. The stamping machine control room includes a display module, a prompt module, a coordinate module, an alarm module and a monitoring module.

[0028] The noise collection module collects the noise intensity of the current stamping workshop in real time, the signal conversion module converts the collected noise into an electrical signal, and the noise discrimination module divides the noise level into three levels: low, medium and high, thereby triggering and switching different operating states of the noise control component 5. The indication module will also trigger the corresponding LED status light to light up, such as different colors, so that when adjacent personnel communicate, they only need to observe whether the LED status light of the headset 1 is on to determine whether the headset 1 is in the noise reduction state, so as to conduct normal language communication without removing the headset; Under the transmission function of the 5G communication module, the personnel in the control room of the stamping machine can grasp the noise level and working conditions of the workshop in real time. The display module can simultaneously display the noise levels in different areas. The prompt module can promptly remind personnel of the low battery condition of earphone 1. The coordinate module can reflect the distribution of personnel in the workshop. When earphone 1 is low on battery and needs to be replaced in time, the coordinate module can be used to quickly locate earphone 1. The alarm module is used for abnormal fault alarm of personnel earphone 1, and the monitoring module is used to monitor the noise conditions of the workshop in real time and continuously.

[0029] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
