Description

Technical Field

[0001] The invention relates to the technical field of cable preparation, in particular to a cable armor wrapping machine. Background Art

[0002] The production process of spirally wrapping various types of strip-shaped, linear metal or non-metallic materials onto the cable core or cable core at a specified pitch is called the wrapping process. This processing method is mostly used for wrapping cable core tapes, armored steel tape wrapping, aluminum (copper) plastic composite tape shielding wrapping, paper insulated cable wrapping insulation, etc. The armored wrapped cable can increase the mechanical strength of the cable and improve its corrosion resistance.

[0003] When wrapping, there is a concept of wrapping angle, that is, the complementary angle between the angle between the wrapping tape and the cable core is defined as the wrapping angle. Under the premise that other conditions remain unchanged, the smaller the wrapping angle, the more turns per unit length, and the slower the production rate. The larger the wrapping angle (the wrapping tape is wrapped longitudinally, and the limit method considers that the wrapping angle is 90°), the more stress the wrapping tape will be subjected to when the cable is bent. If the wrapping tape is not strong enough, it will break. If the strength is enough, it will increase the hardness of the product and affect the flexibility. Therefore, the wrapping angle of the cable armor needs to be selected according to the actual situation.

[0004] The existing cable armor wrapping machines have the following main drawbacks during use: the wrapping angle is difficult to adjust accurately, and the tape frame is prone to shaking during the wrapping process, resulting in changes in the wrapping angle, affecting the wrapping effect. In addition, the existing wrapping mechanism is more troublesome to adjust the tension during wrapping, which is difficult to adjust accurately, and it is necessary to manually confirm the remaining length of the tape on the tape reel and replace it in time when the tape is about to run out, which is more troublesome. Summary of the invention

[0005] The present invention aims to solve one of the technical problems existing in the prior art or related technology.

[0006] To this end, the technical solution adopted in the present invention is:

[0007] A cable armor wrapping machine comprises: a main mechanism and a wrapping mechanism, wherein the main mechanism comprises a driving device, an annular disk mounted on the driving device, a U-shaped frame symmetrically fixed to one side of the annular disk, a frame rotatably mounted on the U-shaped frame, a first driving member mounted on the U-shaped frame and connected to an end of the frame, a first angle sensor mounted on one side of the U-shaped frame and connected to the end of the frame, and a locking member symmetrically mounted on the other side of the U-shaped frame.

[0008] The wrapping mechanism includes a second motor installed on the frame and with its shaft extending through the frame, a placement plate fixed on the shaft of the second motor, a second driving member installed on the frame, an adjustment seat arranged on one side of the frame and meshing with the second driving member, a movable seat movably arranged in the inner cavity of the adjustment seat, a pressure sensor arranged between the movable seat and the inner wall of the adjustment seat, a first roller rotatably sleeved on the movable seat, a guide installed on the frame, and an alarm light installed on the top of the frame.

[0009] The placement plate includes a bottom plate fixed on the second motor shaft, an arc-shaped triangular block symmetrically fixed in the middle of the bottom plate, a bolt fixed in the middle of the bottom plate, a trapezoidal block sleeved on the bolt and located between the opposite arc-shaped triangular blocks, and a nut engaged on the bolt.

[0010] In a preferred example, the present invention can be further configured as follows: the guide member includes a bearing fixed on the frame, a rotating shaft fixed on the inner ring of the bearing, a second roller fixedly sleeved on one end of the rotating shaft, and a second angle sensor installed on the frame through a support rod and connected to the other end of the rotating shaft.

[0011] By adopting the above technical solution, when wrapping, the wrapping tape is released through the second roller, driving the second roller to rotate, and the second angle sensor monitors the number of rotations of the second roller in real time. The number of rotations of the second roller is multiplied by the outer diameter of the second roller to calculate the length of the released wrapping tape.

[0012] In a preferred example, the present invention can be further configured as follows: circular shafts are provided on both sides of the frame, and the circular shafts are rotatably engaged on the U-shaped frame. The first driving member includes a gear ring fixedly sleeved on the circular shaft on one side of the frame, a first motor installed on the U-shaped frame, a gear fixed on the first motor shaft, and a toothed belt with one end sleeved on the gear and the other end sleeved on the gear ring.

[0013] By adopting the above technical solution, when the first motor is started, it drives the gear to rotate, and the rotation of the gear drives the gear ring to rotate through the toothed belt. The rotation of the gear ring drives the circular shaft to rotate, that is, drives the frame to rotate. The rotation of the frame drives the wrapping mechanism installed on the frame to rotate, thereby adjusting the wrapping angle between the wrapping mechanism and the cable.

[0014] In a preferred example, the present invention can be further configured as follows: the locking member includes a shell fixed on the U-shaped frame, an electric telescopic rod installed on the top of the shell and extending into the inner cavity of the shell, and a friction block fixed at the end of the electric telescopic rod.

[0015] By adopting the above technical solution, when the wrapping angle between the frame and the cable is adjusted, the electric telescopic rod drives the friction block to press against the circular shaft on one side of the frame, thereby fixing the frame and preventing the frame from shaking during the rotation of the annular disk and affecting the wrapping angle.

[0016] In a preferred example, the present invention can be further configured as follows: the second driving member includes a fixing plate symmetrically fixed on the frame, a threaded rod rotatably installed between the relatively fixing plates, and a third motor installed on one side fixing plate and with its shaft fixedly connected to the end of the threaded rod.

[0017] By adopting the above technical solution, the fixing plate can ensure the stability of the threaded rod, and the third motor is used to drive the threaded rod to rotate, and the rotation of the threaded rod drives the adjustment seat to move.

[0018] In a preferred example, the present invention can be further configured as follows: the adjustment seat includes a U-shaped plate arranged on one side of the frame and a threaded sleeve with one end fixed to the U-shaped plate and the other end passing through the frame and sleeved on the threaded rod, and the threaded rod and the threaded sleeve are engaged with each other.

[0019] By adopting the above technical solution, the U-shaped plate is used to install the movable seat, and the threaded sleeve is engaged with the threaded rod. When the third motor drives the threaded rod to rotate, the rotation of the threaded rod drives the threaded sleeve to move, and the movement of the threaded sleeve drives the adjustment seat to move, that is, drives the first roller to move, thereby adjusting the tension of the wrapping tape.

[0020] In a preferred example, the present invention can be further configured as follows: grooves are provided on the opposite inner sides of the U-shaped plate, and the two sides of the movable seat are embedded in the grooves.

[0021] By adopting the above technical solution, the movement of the movable seat can be limited. The greater the tension of the wrapping tape, the greater the pressure on the first roller. The movable seat can transfer the pressure to the pressure sensor, making it convenient for the pressure sensor to monitor the pressure on the movable seat in real time.

[0022] In a preferred example, the present invention can be further configured as follows: the output end of the second angle sensor is electrically connected to the input end of the warning light through an electric wire.

[0023] By adopting the above technical solution, when the second angle sensor calculates that the tape on the tape reel is about to run out, the alarm light is activated to alert the worker, reminding the worker to replace the tape reel as soon as possible.

[0024] By adopting the above technical solution, the beneficial effects achieved by the present invention are:

[0025] 1. In the present invention, two U-shaped frames are symmetrically installed on the annular disk, and a frame is installed on the U-shaped frame, and the wrapping mechanism is installed on the frame. At the same time, a first driving member is installed on one side of the U-shaped frame to be connected to the frame. The first driving member can drive the pitch angle adjustment of the frame relative to the annular disk, that is, adjust the wrapping angle between the wrapping mechanism installed on the frame and the cable. In addition, a first angle sensor is installed on one side of the U-shaped frame. The first angle sensor can be used to monitor the pitch angle of the frame, that is, the wrapping angle of the wrapping mechanism in real time, to achieve automatic and high-precision wrapping angle adjustment, thereby increasing the level of automation. In addition, a locking member is installed on the other side of the U-shaped frame, which can lock the frame after the frame angle adjustment is completed, thereby avoiding the frame shaking during the rotation and bypassing of the annular disk, resulting in a change in the wrapping angle, thereby ensuring the effect of cable armor wrapping.

[0026] 2. In the present invention, a first motor is installed on a frame, and a placement plate is installed on the shaft of the first motor. The placement plate is composed of a base plate, an arc-shaped triangular block, bolts, a trapezoidal block and a nut. It can be applied to tape reels of different sizes, and the tape reels are convenient to fix and easy to install and disassemble.

[0027] 3. In the present invention, a second driving member is installed on one side of the frame, and an adjusting seat is arranged on the other side. The adjusting seat is driven to move by the second driving member, and a movable seat is movably arranged in the adjusting seat. A pressure sensor is arranged between the movable seat and the inner bottom wall of the adjusting seat. A first roller is installed on the movable seat as a tension adjusting wheel. When in use, the tape reel is fixed on the placement reel, the tape is passed around the first roller, and then passed around the guide member to be wound around the cable. At this time, the second driving member drives the adjusting seat to move, so that the tension of the tape can be automatically adjusted, and the tension of the tape can be converted into pressure and transmitted to the pressure sensor. Through the monitoring of the pressure sensor, precise control of the tension of the tape can be achieved.

[0028] 4. In the present invention, the guide member is composed of a bearing, a rotating shaft, a second roller and a second angle sensor. The second angle sensor can monitor the number of rotations of the second roller in real time. The length of the released tape can be calculated by multiplying the number of rotations of the second roller by the outer diameter of the second roller. When the length of the released tape is close to the length of the tape on the tape reel, the alarm light is activated to remind the worker to replace the tape reel, thereby ensuring the timeliness of the tape replacement and avoiding the trouble of manual confirmation.

DETAILED DESCRIPTION

[0041] To make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in combination with specific implementations and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0042] Some embodiments of the present invention are described below in conjunction with the accompanying drawings. Figure 1-Figure 9 , a cable armor wrapping machine, comprising: a main body mechanism 100 and a wrapping mechanism 200.

[0043] The main mechanism 100 includes a driving device 110, an annular disk 120 installed on the driving device 110, a U-shaped frame 130 symmetrically fixed on one side of the annular disk 120, a frame 140 rotatably installed on the U-shaped frame 130, a first driving member 150 installed on the U-shaped frame 130 and connected to an end of the frame 140, a first angle sensor 160 installed on one side of the U-shaped frame 130 and connected to the end of the frame 140, and a locking member 170 symmetrically installed on the other side of the U-shaped frame 130.

[0044] The driving device 110 is used to install the annular disk 120 and drive the annular disk 120 to rotate. The rotation of the annular disk 120 drives the wrapping mechanism 200 to rotate, which facilitates the cable wrapping operation. An empty pipe is provided in the middle of the driving device 110 for the cable to pass through.

[0045] The U-shaped frame 130 is fixed on the annular plate and used to install the frame 140. A circular shaft 141 is provided on both sides of the frame 140. The circular shaft 141 is rotatably engaged with the U-shaped frame 130 to ensure the stability of the frame 140 when rotating. The first driving member 150 is used to drive the frame 140 to rotate, including a gear ring 151 fixedly sleeved on the circular shaft 141 on one side of the frame 140, a first motor 152 installed on the U-shaped frame 130, a gear 153 fixed on the shaft of the first motor 152, and a first driving member 150. A toothed belt 154 is sleeved on one end of the gear 153 and on the other end of the gear ring 151. When the first motor 152 is started, the gear 153 is driven to rotate. The gear 153 rotates through the toothed belt 154 to drive the gear ring 151 to rotate. The rotation of the gear ring 151 drives the circular shaft 141 to rotate, that is, drives the frame 140 to rotate. The rotation of the frame 140 drives the wrapping mechanism 200 installed on the frame 140 to rotate, adjust the wrapping angle between the wrapping mechanism 200 and the cable, and realize automatic adjustment of the wrapping angle.

[0046] The first angle sensor 160 is installed on one side of the U-shaped frame 130 and fixedly connected to the end of the circular shaft 141 on one side of the frame 140. It is used to monitor the rotation angle of the frame 140 in real time and cooperate with the first driving member 150 to realize automatic and high-precision adjustment of the wrapping angle.

[0047] The locking piece 170 is used to lock the frame 140 after the angle adjustment of the frame 140 is completed to prevent the frame 140 from shaking during the rotation of the annular disk 120, and includes a shell 171 fixed on the U-shaped frame 130, an electric telescopic rod 172 installed at the top of the shell 171 and extending into the inner cavity of the shell 171, and a friction block 173 fixed at the end of the electric telescopic rod 172. The shell 171 is used to install the electric telescopic rod 172 and limit the movement of the friction block 173. The electric telescopic rod 172 is used to drive the friction block 173 to move. When the wrapping angle between the frame 140 and the cable is adjusted, the electric telescopic rod 172 drives the friction block 173 to press against the circular shaft 141 on one side of the frame 140 to fix the frame 140 to prevent the frame 140 from shaking during the rotation of the annular disk 120 and affecting the wrapping angle.

[0048] The wrapping mechanism 200 is installed on the frame 140 and is used to place the wrapping disk, including a second motor 210 installed on the frame 140 and with its shaft extending through the frame 140, a placement disk 220 fixed on the shaft of the second motor 210, a second driving member 230 installed on the frame 140, an adjustment seat 240 arranged on one side of the frame 140 and engaged with the second driving member 230, a movable seat 250 movably arranged in the inner cavity of the adjustment seat 240, a pressure sensor 260 arranged between the movable seat 250 and the inner wall of the adjustment seat 240, a first roller 270 rotatably sleeved on the movable seat 250, a guide member 280 installed on the frame 140, and an alarm light 290 installed on the top of the frame 140.

[0049] The second motor 210 is used to install the placement disk 220 and drive the placement belt to rotate at a uniform speed. The placement disk 220 rotates at a uniform speed, which drives the tape wrapping disk to rotate at a uniform speed, and releases the tape on the tape wrapping disk at a uniform speed.

[0050] The placing plate 220 is used to fix the tape wrapping plate to ensure the stability of the tape wrapping plate, including a bottom plate 221 fixed on the shaft of the second motor 210, an arc-shaped triangular block 222 symmetrically fixed to the middle of the bottom plate 221, a bolt 223 fixed to the middle of the bottom plate 221, a trapezoidal block 224 sleeved on the bolt 223 and located between the opposite arc-shaped triangular blocks 222, and a nut 225 engaged with the bolt 223. The bottom plate 221 is used to install other components, the arc-shaped triangular blocks 222 are symmetrically arranged, and the trapezoidal blocks 224 are symmetrically arranged. 24 is embedded between the relatively arc-shaped triangular blocks 222, and the inclined surfaces of the two are staggered. When the tape reel is fixed, the inclined surfaces on the arc-shaped triangular block 222 and the trapezoidal block 224 cooperate with each other, which can ensure the stability of the tape reel and can be applied to tape reels with different inner diameters, increasing the scope of application. The bolt 223 is used to engage with the nut 225, and the nut 225 is engaged with the bolt 223 to fix the trapezoidal block 224, thereby ensuring the stability of the tape reel fixation and facilitating installation and disassembly.

[0051] The second driving member 230 is used to drive the adjustment seat 240 to move, including a fixed plate 231 symmetrically fixed on the frame 140, a threaded rod 232 rotatably installed between the relatively fixed plates 231, and a third motor 233 installed on one side of the fixed plate 231 and with its shaft fixedly connected to the end of the threaded rod 232. At the same time, the adjustment seat 240 includes a U-shaped plate 241 arranged on one side of the frame 140 and a threaded sleeve 242 with one end fixed on the U-shaped plate 241 and the other end passing through the frame 140 and sleeved on the threaded rod 232. The threaded rod 232 and the threaded sleeve 242 are meshed with each other, so that when the third motor 233 is started, it drives the threaded rod 232 to rotate, the rotation of the threaded rod 232 drives the threaded sleeve 242 to move, and the movement of the threaded sleeve 242 drives the U-shaped plate 241 to move, that is, drives the first roller 270 to move, so as to adjust the tension of the wrapping tape.

[0052] Grooves 2411 are provided on the relative inner side surfaces of the U-shaped plate 241, and the two sides of the movable seat 250 are embedded in the grooves 2411. The pressure sensor 260 is fixed on the inner bottom wall of the U-shaped plate 241, and the top end is close to the bottom of the movable seat 250. The first roller 270 is rotatably sleeved on the movable seat 250. When the tension of the wrapping tape is adjusted, the greater the tension of the wrapping tape, the greater the pressure on the first roller 270. The movable seat 250 can transmit the pressure to the pressure sensor 260, so that the pressure sensor 260 can monitor the pressure on the movable seat 250 in real time.

[0053] The guide member 280 is used to release the tape, and includes a bearing 281 fixed on the frame 140, a rotating shaft 282 fixed on the inner ring of the bearing 281, a second roller 283 fixedly sleeved on one end of the rotating shaft 282, and a second angle sensor 284 installed on the frame 140 through a support rod and connected to the other end of the rotating shaft 282. The bearing 281 is used to install the rotating shaft 282 to ensure the stability of the rotation of the rotating shaft 282. The rotating shaft 282 is used to install the second roller 283. The second roller 283 is used to guide the tape to be released. The second angle sensor 284 monitors the number of rotations of the rotating shaft 282, that is, the number of rotations of the second roller 283, in real time. The number of rotations of the second roller 283 is multiplied by the outer diameter of the second roller 283 to calculate the length of the tape released. When the length of the tape released is close to the length of the tape on the tape reel, the alarm light 290 is activated to remind the worker to replace the tape reel.

[0054] The working principle and use process of the present invention are as follows: when in use, unscrew the nut 225, remove the trapezoidal seat from the bolt 223, sleeve the middle part of the tape tray on the outside of the two arc-shaped triangular blocks 222, insert the trapezoidal seat into the bolt 223, and fit it between the two arc-shaped triangular blocks 222. At this time, the inclined surfaces on the arc-shaped triangular block 222 and the trapezoidal block 224 cooperate with each other to fix the tape tray, screw the nut 225 into the bolt 223, fix the trapezoidal block 224, and the installation of the tape tray is completed. The disassembly is similar. The tape on the tape reel is pulled out, passed around the first roller 270 and the second roller 283 and wound around the cable surface, and then the armor wrapping operation can be started. During the wrapping, when it is necessary to adjust the wrapping angle, the first motor 152 is started, and the first motor 152 rotates to drive the gear 153 to rotate, and the gear 153 rotates through the toothed belt 154 to drive the gear ring 151 to rotate, and the gear ring 151 rotates to drive the circular shaft 141 to rotate, and the circular shaft 141 rotates to drive the frame 140 to rotate, that is, the wrapping angle is adjusted. When the frame 140 rotates, the first angle sensor 152 is turned on. The sensor 160 monitors the rotation angle of the frame 140 in real time to ensure the accuracy of the angle adjustment. After the adjustment is completed, the electric telescopic rod 172 drives the friction block 173 to extend and press on the circular shaft 141 on one side of the frame 140 to fix the circular shaft 141, thereby preventing the frame 140 from shaking during the rotation of the annular disk 120. At the same time, the third motor 233 is started to drive the threaded rod 232 to rotate, and the rotation of the threaded rod 232 drives the threaded sleeve 242 to move, that is, drives the U-shaped plate 241 to move, and the U-shaped plate 241 is moved. The movement of the first roller 270 drives the movement of the first roller 270, so as to adjust the tension of the tape. In addition, when wrapping, the tape is released through the second roller 283, driving the second roller 283 to rotate. The second angle sensor 284 monitors the number of rotations of the second roller 283 in real time. The number of rotations of the second roller 283 is multiplied by the outer diameter of the second roller 283 to calculate the length of the released tape. When the length of the released tape is close to the length of the tape on the tape reel, the alarm light 290 is activated to remind the worker to replace the tape reel.
