Description

Technical Field

[0001] This application relates to the field of cable production equipment, and in particular to an airbag fixing device for cable production interruption and changeover. Background Technology

[0002] To meet production demands, companies frequently need to perform line stoppages for changeovers. These stoppages aim to quickly switch production lines to accommodate different product models and specifications by adjusting equipment parameters, changing molds or tools. This process involves the coordinated operation of multiple production stages. The production line itself (such as conveyor lines and traction lines) is a key component for material transport and process integration; its stable operation is crucial for ensuring production efficiency. Under normal production conditions, the production line maintains smooth operation through precise tension control, ensuring that materials are transported according to predetermined speeds and paths.

[0003] In actual production line shutdown and changeover processes, when the tension control system on the production line malfunctions and cannot maintain the cable tension during the changeover period, the cable is prone to losing tension and falling onto the production line. When the cable falls, it will collide with other equipment, easily becoming damaged, dirty, and scratched. Moreover, when production is resumed, it is necessary to re-thread the cable, reducing production efficiency. Repairing the tension control system takes a certain amount of time, during which production is difficult to carry out. Summary of the Invention

[0004] To address the technical problem of difficulty in changing production during the maintenance of tension control systems, this application provides an airbag fixing device for changing production during wire and cable line shutdowns.

[0005] The technical solution of the airbag fixing device for wire and cable production stoppage and changeover provided in this application is as follows:

[0006] An airbag fixing device for cable production stoppage and changeover includes a base, a support rod fixed on the base, an angle control component at the upper end of the support rod, a vertical plate above the angle control component, the angle control component controlling the tilt angle of the vertical plate, two mounting plates fixed on the vertical plate, mounting blocks on one side of each mounting plate, telescopic airbags mounted on the mounting blocks, an air pump mounted on the base, and the air pump connected to the telescopic airbags via a hose, a pressure relief solenoid valve connected to the hose for venting the telescopic airbags, and a signal receiver module mounted on the base for receiving stoppage signals.

[0007] By adopting the above technical solution, the angle control component can adjust the tilt angle of the vertical plate, which can be used for cables with different tilt angles. The cable is passed between the two mounting plates. When the signal receiver module receives the stop signal from the host, the air pump starts to inflate the two telescopic airbags. The two telescopic airbags clamp and fix the cable, thereby maintaining the tension of the cable when the line stops. In the event of a failure of the tension control system and the inability to maintain the cable tension during production changeover, the normal production changeover can be guaranteed. Moreover, the device has a simple structure, is easy to move, and has good portability, making it convenient to move and use in the workshop.

[0008] Preferably, the support rod includes a sleeve fixed to the base, a lifting rod is slidably inserted inside the sleeve, and a first fastening bolt is threaded onto the side wall of the sleeve. The end of the first fastening bolt abuts against the lifting rod to fix the lifting rod.

[0009] By adopting the above technical solution, the lifting rod can slide in the sleeve and be fixed by the first fastening bolt, which can change the height of the support rod, thereby improving the clamping ability of cables of different heights, expanding the application range of the device, and improving its practical value.

[0010] Preferably, the angle control component includes a connecting seat fixed to the upper end of the support rod, the connecting seat is rotatably connected to a rotating disk via a rotating shaft, and a second fastening bolt is threaded onto the connecting seat, with the end of the second fastening bolt abutting against the rotating disk to fix the rotating disk.

[0011] By adopting the above technical solution, the rotating disk can rotate on the connecting seat and be fixed by the second fastening bolt, which can change the tilt angle of the vertical plate, thereby clamping cables with different tilt angles and further expanding the applicability of the device.

[0012] Preferably, a base plate is fixed above the rotating disk, a vertical rod is fixed on the base plate, a top plate is provided at the upper end of the vertical rod, a connecting plate is fixed at the bottom of the vertical plate, and the vertical rod slides through the connecting plate. A first balance spring and a second balance spring are fixed on the upper and lower sides of the connecting plate, respectively. The first balance spring abuts against the top plate, and the second balance spring abuts against the base plate.

[0013] By adopting the above technical solution, under the action of the first and second balance springs, the connecting plate can be held between the top plate and the bottom plate, and can move freely along the vertical rod. When the cable is not in the middle of the two telescopic airbags, it can automatically adjust its position during clamping to prevent one of the telescopic airbags from providing excessive lateral thrust to the cable, causing the cable to deviate and ensuring the stability of the cable.

[0014] Preferably, the mounting plate has a sliding groove, and the mounting block is slidably disposed in the sliding groove. Both sides of the mounting block are provided with a pressure relief valve, and the pressure relief valve is connected to the inside of the telescopic airbag. Both sides of the mounting block are provided with a stabilizing spring, and the two ends of the stabilizing spring abut against the inner wall of the end of the mounting block and the sliding groove, respectively.

[0015] By adopting the above technical solution, if the signal receiver module experiences signal delay or damage, the telescopic airbag will still be clamped on the cable when production resumes. At this time, the cable moves, and its tension is greater than the tension set by the production line. The telescopic airbag moves with the cable and compresses the stabilizing spring on one side. Then, the pressure relief valve on that side will press against the end side wall of the slide to release the pressure of the telescopic airbag and prevent the cable from being damaged or broken.

[0016] Preferably, the mounting block has an internal cavity, and the telescopic airbag and the pressure relief valve are both connected to the cavity. The bottom of the slide groove has a long slot, and the upper end of the mounting block is connected to a connecting pipe, which is connected to the cavity. The hose has one air inlet and two air outlets. The air inlet is connected to an air pump, and the two air outlets are connected to two connecting pipes respectively.

[0017] By adopting the above technical solution, the air pump can inflate the two telescopic airbags through the hose. At the same time, pressing the pressure relief valve can also depressurize the telescopic airbags. In addition, the hose can be bent arbitrarily when adjusting the position of the vertical plate, making adjustment more convenient.

[0018] Preferably, the end of the telescopic airbag is fixed with an anti-slip pad.

[0019] By adopting the above technical solution, when the anti-slip pad comes into contact with the cable, it can increase the clamping force of the telescopic airbag on the cable, and further improve the stability of the cable.

[0020] Preferably, the base has several grooves, and the grooves contain an adjustable number of counterweights.

[0021] By adopting the above technical solution, the device is lighter and easier to move when the counterweight is removed. When the device is in use, placing the counterweight in the groove can improve the stability of the device and prevent it from tipping over.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. When the signal receiver module receives a stop signal from the host, the air pump inflates the two telescopic airbags to clamp the cable. When the tension control system on the production line malfunctions and cannot maintain the cable tension during production stoppage, this device can be placed in an appropriate position to maintain the cable tension during production stoppage and changeover, thus ensuring normal production changeover.

[0024] 2. By adjusting the angle of the vertical plate and the support rod, the position and angle of the vertical plate can be changed, thereby changing the clamping angle of the two telescopic airbags. When the cable is at different heights and different tilt angles, it can still provide a stable clamping force on the cable, thus expanding the applicability of the device.

[0030] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0031] This application discloses an airbag fixing device for wire and cable production shutdown and changeover.

[0032] Example 1

[0033] Reference Figure 1 An airbag fixing device for power cable production stoppage and changeover includes a base 1, on which an air pump 6, a signal receiver module 9, and a support rod are mounted. The signal receiver module 9 receives stoppage signals. An angle control component is located at the upper end of the support rod, and a vertical plate 2 is positioned above the angle control component, which adjusts the tilt angle of the vertical plate 2. Two mounting plates 3 are fixed to the vertical plate 2, and mounting blocks 4 are located on the sides of the two mounting plates 3 that are close to each other. Telescopic airbags 5 are mounted on the mounting blocks 4. The air pump 6 is connected to the telescopic airbag 5 via a flexible hose 7, which is also connected to a pressure relief solenoid valve 8 for venting the telescopic airbag 5.

[0034] The above-mentioned design makes the device simple in structure, portable, and easy to move. It can be flexibly adapted to the needs of different locations in the workshop and can be used as an emergency device when the tension control system fails or the cable tension cannot be maintained during production stoppage.

[0035] In use, the moving device allows the cable to pass through the space between the two mounting plates 3 on the vertical plate 2. When the signal receiver module 9 receives the stop signal, the air pump 6 starts and inflates the telescopic airbags 5 on the two mounting blocks 4, so that the two anti-slip pads 27 press against the cable and clamp and fix the cable from both sides, thereby maintaining the tension of the cable during the stop. In addition, the angle control component can flexibly adjust the tilt angle of the vertical plate 2 to adapt to various cables with different tilt angles.

[0036] Reference Figure 1 and Figure 2 The angle control component includes a connecting seat 13 fixed to the upper end of the support rod. A rotating disk 14 is rotatably connected to the connecting seat 13 via a rotating shaft. The rotating disk 14 can rotate around the rotating shaft to adjust the angle. A second fastening bolt 15 is also threaded onto the connecting seat 13. When the rotating disk 14 is adjusted to a suitable angle, the second fastening bolt 15 is tightened so that its end abuts against the rotating disk 14, thereby fixing the rotating disk 14.

[0037] The support rod consists of a sleeve 10 and a lifting rod 11. The sleeve 10 is fixed on the base 1, and the lifting rod 11 is slidably inserted inside the sleeve 10 and can slide up and down along the sleeve 10. Moreover, a first fastening bolt 12 is threaded on the side wall of the sleeve 10, and the end of the first fastening bolt 12 abuts against the lifting rod 11 to fix the lifting rod 11.

[0038] With the above settings, the height of the support rod can be adjusted, and the rotating disk 14 in the angle adjustment component can rotate to adjust the angle and height of the vertical plate 2, thereby adjusting the clamping angle and height of the two telescopic airbags 5. When the height and angle of the cable are different, it can be stably clamped, which has a wide range of applications and is convenient for practical use.

[0039] refer to Figure 2 A base plate 16 is fixedly installed above the rotating disk 14. A vertical rod 17 is vertically fixed on the base plate 16. The vertical rod 17 extends upward and a top plate 18 is installed at its upper end, forming a stable vertical support frame.

[0040] A connecting plate 19 is fixed to the bottom of the vertical plate 2. The connecting plate 19 has holes that fit the vertical rod 17, allowing the vertical rod 17 to slide through the connecting plate 19. The vertical plate 2 can then slide up and down on the vertical rod 17 to a certain extent. A first balance spring 20 and a second balance spring 21 are installed on the upper and lower sides of the connecting plate 19, respectively. The first balance spring 20 abuts against the top plate 18, and the second balance spring 21 abuts against the bottom plate 16.

[0041] With the above settings, under the combined action of the first balance spring 20 and the second balance spring 21, the connecting plate 19 is stably held between the top plate 18 and the bottom plate 16, and can move freely along the vertical rod 17, so that the position of the vertical plate 2 can also move up and down.

[0042] In practical applications, when the cable is not accurately positioned in the exact middle of the two telescopic airbags 5, the connecting plate 19 and the vertical plate 2 can move freely during the clamping process of the telescopic airbags 5. They will automatically adjust their positions to adapt to the actual position of the cable, which can effectively prevent one of the telescopic airbags 5 from applying excessive lateral thrust to the cable, thereby preventing the cable from shifting and ensuring the stability of the cable during the clamping process.

[0043] refer to Figure 3 The mounting plate 3 has a sliding groove 22, and the mounting block 4 is slidably disposed in the sliding groove 22 and can slide along the sliding groove 22. Both sides of the mounting block 4 are provided with a press-to-release valve 23, and the press-to-release valve 23 is connected to the inside of the telescopic airbag 5. Stabilizing springs 24 are also provided on both sides of the mounting block 4. The two ends of the stabilizing springs 24 abut against the inner walls of the mounting block 4 and the sliding groove 22 respectively. The stabilizing springs 24 can provide a certain elastic support for the mounting block 4, so that it maintains a relatively stable position in the sliding groove 22.

[0044] With the above settings, if the signal receiver module 9 experiences abnormalities such as signal delay during production, the telescopic airbag 5 may remain clamped on the cable when production resumes. When the production line starts running, the cable will move accordingly. During the movement of the cable, it will be clamped by the telescopic airbag 5, increasing the tension, and the telescopic airbag 5 will move along with the cable.

[0045] During movement, the telescopic airbag 5 compresses the stabilizing spring 24 on one side. As the telescopic airbag 5 continues to move, the pressure relief valve 23 on that side gradually presses against the end side wall of the slide groove 22. When the pressure relief valve 23 contacts the end side wall of the slide groove 22, it triggers the pressure relief action to release the pressure of the telescopic airbag 5.

[0046] This pressure relief mechanism effectively prevents cable damage or breakage caused by excessive cable tension, ensuring smooth production.

[0047] refer to Figure 4 The mounting block 4 has an internal cavity, through which the telescopic airbag 5 and the pressure relief valve 23 are connected, allowing gas to flow smoothly and achieve the pressure relief function. The bottom of the slide groove 22 has a long slot 25, and the upper end of the mounting block 4 is connected to a connecting pipe 26 that communicates with the cavity. Through the connecting pipe 26, the hose 7 is provided with an air inlet and two air outlets. The air inlet is connected to the air pump 6, and the gas generated by the air pump 6 enters the hose 7 through the air inlet. The two air outlets are connected to the two connecting pipes 26 respectively. In this way, the gas generated by the air pump 6 can enter the cavity of the mounting block 4 through the hose 7 and the connecting pipe 26, thereby inflating the telescopic airbag 5.

[0048] refer to Figure 1 The base 1 has several grooves 28 and a counterweight 29 that matches the grooves 28, which can be freely removed and placed.

[0049] With the above settings, the device is lighter and easier to move when the counterweight 29 is removed. When the device is in use, placing the counterweight 29 in the groove 28 can improve the stability of the device and prevent it from tipping over.

[0050] The implementation principle of this embodiment is as follows:

[0051] The angle control component can adjust the tilt angle of the vertical plate 2, making it suitable for cables with different tilt angles. The height of the support rod can be adjusted, thereby improving the clamping capacity for cables of different heights. When using the device, the cable passes between the two mounting plates 3 by adjusting the height and angle. When the signal receiver module 9 receives the stop signal from the host, the air pump 6 starts to inflate the two telescopic air bags 5, clamping and fixing the cable through the two telescopic air bags 5, thus maintaining the cable tension when the line stops. In the event of a malfunction in the tension control system and the inability to maintain cable tension during production changeover, the device ensures the normal operation of the changeover. Moreover, the device has a simple structure, is easy to move, and has good portability, making it convenient to move and use within the workshop.

[0052] In summary, this device can maintain cable tension and prevent the cable from falling during production changeover by clamping the cable with two telescopic airbags 5. When the tension control system on the production line malfunctions and cannot maintain cable tension during production changeover, it ensures the normal progress of production changeover.

[0053] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
