In this process, fillers are needed to fill the gaps when the wire cores are twisted. The reel length of the filler wire is short. Frequent parking and replacement of fillers and joints during use lead to slow actual production speed and high labor intensity, which seriously affects production efficiency. The more filler joints there are, the more impact on appearance quality. In addition, with the development of the industry, there is an increasing demand for long-length multi-core cables at this stage.

In the initial state, the two ends of the locking card plate are in contact with the ends of the slots of the two fixed blocks. The activation of the fourth driving structure drives the two locking card plates to move away from each other, so that the two ends of the locking card plate can be moved into the slots of the two fixed blocks at the same time, effectively locking the position of the lifting base. When the filling rope is placed on the lifting base, the stabilizing effect of the locking card plate can avoid the lifting base from moving downward prematurely due to local force, thereby allowing the filling rope to be stably placed on the lifting base and achieving stable descent of the filling rope.

DETAILED DESCRIPTION

[0031] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0032] Reference Figures 1 to 12As shown: a new type of high-efficiency PP filling rope unloading device, including a mobile base 1, a guide structure 2 and two unloading structures 3; the guide structure 2 is arranged in the middle of the mobile base 1, and the guide structure 2 includes a guide component 21 and a lifting component 22, the guide component 21 is arranged at the upper end of the lifting component 22, and the lifting component 22 is arranged in the middle of the mobile base 1; the two unloading structures 3 are respectively arranged on both sides of the guide structure 2, and the unloading structure 3 includes a vertical unloading rack 31, a lifting base 32, four reset guide structures 33 and a locking structure 34, the lower end of the vertical unloading rack 31 is connected to the mobile base 1, and the lifting base 32 It is horizontally arranged inside the vertical material unloading rack 31, and four reset guide structures 33 are respectively arranged on the four corners of the lifting base 32. The reset guide structure 33 includes a second guide column 331 and a second spring 332. The second guide column 331 is perpendicular to the lifting base 32, and both ends of the second guide column 331 are connected to the upper and lower ends of the vertical material unloading rack 31. The second spring 332 is arranged at the lower end of the lifting base 32, and the second spring 332 is sleeved on the second guide column 331. The two ends of the second spring 332 are respectively abutted against the ends of the lifting base 32 and the second guide column 331, and the locking structure 34 is arranged at the lower end of the lifting base 32.

[0033] The new filling rope has a larger packaging size and can provide filling rope continuously and uninterruptedly, reducing the number of joints between filling ropes in the cable and reducing the quality risks of cable products. However, the packaging height of the new filling rope is relatively high, which is not convenient for connecting two filling ropes. For this reason, a discharging device is provided. In the initial state, the locking structure 34 stably fixes the height of the lifting base 32 to ensure the stable placement of the filling rope. Subsequently, the operator places the two new filling ropes on the two lifting bases 32 respectively. After that, the locking structure 34 releases the fixing effect on the lifting base 32. At this time, the lifting base 32 and the filling rope carried thereon apply downward pressure to the second spring 332, causing the second spring 332 to be compressed, thereby prompting the lifting base 32 to move downward along the second guide column 331 to lower the height of the top of the filling rope. Then, the lifting component 22 starts and drives the guide component 2 1 is lowered to adapt to the adjusted height of the filling rope. Subsequently, the operator passes one end of one of the filling ropes through the guide assembly 21 to smoothly connect it to the production process of the cable. As the production process proceeds, the filling rope is gradually consumed, and the downward pressure on the second spring 332 under the corresponding lifting base 32 is gradually reduced, prompting the lifting base 32 to slowly rise under the elastic force of the second spring 332. When the filling rope on the lifting base 32 is completely consumed, the lifting base 32 is reset to the initial position and is re-fixed by the locking structure 34. At the same time, the second spring 332 under the lifting base 32 corresponding to the spare filling rope is compressed due to the weight of the filling rope, so that the top height of the spare filling rope is reduced, which is convenient for the operator to quickly and conveniently connect the two filling ropes, thereby effectively reducing the time required for connecting the filling ropes and improving the overall production efficiency.

[0034] Reference Figure 3 and Figure 4 As shown: the locking structure 34 includes two locking clamps 341, four fixed blocks 342 and a fourth driving structure 343; the two locking clamps 341 are symmetrically arranged about the middle surface of the lifting base 32; the four fixed blocks 342 are respectively arranged at the two ends of the two locking clamps 341, and a clamping groove is provided on the opposite side of the two fixed blocks 342 at the same end of the two locking clamps 341, and the fixed blocks 342 are connected to the vertical material rack 31; the fourth driving structure 343 is arranged between the two locking clamps 341.

[0035] If the lifting base 32 is supported only by the second spring 332, the filling rope may not be placed stably when placing the filling rope, and the lifting base 32 will move downward due to local force, causing the filling rope to tilt. Therefore, in the initial state of the lifting base 32, the two ends of the locking card plate 341 abut against the ends of the slots of the two fixing blocks 342 to prevent the locking card plate 341 from continuing to move upward. Then the fourth driving structure 343 is started, and the fourth driving structure 343 drives the two locking card plates 341 away from each other, and the two ends of the locking card plate 341 move into the slots of the two fixing blocks 342 at the same time. The slots limit the locking card plate 341 in the vertical direction to prevent the locking card plate 341 from moving downward. Therefore, the position of the lifting base 32 remains fixed, so that the filling rope is stably placed on the lifting base 32, and the filling rope is stably lowered.

[0036] Reference Figure 4 and Figure 5 As shown: the fourth driving structure 343 includes two bidirectional screw rods 3431, two fifth gears 3432 and a sixth gear 3433; the two bidirectional screw rods 3431 are arranged in parallel between the two locking card plates 341, and the two ends of the bidirectional screw rods 3431 are provided with second moving blocks 3434, the second moving blocks 3434 are threadedly connected with the bidirectional screw rods 3431, and a second driving plate 3435 is arranged on one side of the second moving block 3434, and the two ends of the second driving plate 3435 are respectively axially connected with the second moving block 3434 and the middle part of the locking card plate 341; the two fifth gears 3432 are respectively arranged at the same end of the two bidirectional screw rods 3431; the sixth gear 3433 is arranged between the two fifth gears 3432, and the sixth gear 3433 is meshed with the two fifth gears 3432.

[0037] When the lifting base 32 is in the initial position, the sixth gear 3433 rotates forward, driving the two fifth gears 3432 to rotate synchronously. The two fifth gears 3432 respectively drive the two bidirectional screw rods 3431 to rotate. The two second moving blocks 3434 of the bidirectional screw rods 3431 approach each other. The two second driving plates 3435 apply a thrust toward the card slot to the locking card plate 341, so that the locking card plate 341 is inserted into the card slot, and the lifting base 32 is locked. When the new filling rope is stably placed on the lifting base 32, the sixth gear 3433 Reverse rotation, the two fifth gears 3432 drive the two bidirectional screw rods 3431 to rotate in the opposite direction, the two second moving blocks 3434 on the bidirectional screw rods 3431 move away from each other, and the two second driving plates 3435 apply a pulling force to the locking card plate 341 away from the card slot. Since the two bidirectional screw rods 3431 rotate synchronously, the two locking card plates 341 move synchronously, so that the lifting base 32 can be subjected to or lose the force applied by the two locking card plates 341 at the same time, thereby helping to maintain the stability of the lifting base 32 during the locking and releasing process.

[0038] Reference Figure 4 and Figure 6 As shown: the locking structure 34 also includes four rolling assemblies 344, each two of the four rolling assemblies 344 form a group, and the two rolling assemblies 344 in a group are respectively arranged at both ends of the locking card plate 341, and the rolling assembly 344 includes a mounting plate 3441 and a plurality of third rollers 3442, the mounting plate 3441 is connected to the end of the locking card plate 341, and the plurality of third rollers 3442 are equidistantly arranged on the mounting plate 3441.

[0039] The lifting base 32 is preferably pressed against the locking plate 341 and the fixing block 342 to prevent the lifting base 32 from sliding out of the locking plate 341 and the fixing block 342.

[0040] Reference Figure 3 , Figure 4 and Figure 7 As shown: the locking structure 34 also includes two limiting guide structures 345, and the two limiting guide structures 345 are respectively arranged on both sides of the two locking clamps 341, and the limiting guide structure 345 includes a second guide rod 3451, and the second guide rod 3451 is perpendicular to the bidirectional screw rod 3431, one end of the second guide rod 3451 is connected to the lifting base 32, and the locking clamp 341 is slidably connected to the second guide rod 3451, and the second guide rod 3451 is also sleeved with a third spring 3452, and the two ends of the third spring 3452 are respectively abutted against the end of the second guide rod 3451 and the locking clamp 341.

[0041] The second guide rod 3451 limits the movement of the locking card plate 341, so that the locking card plate 341 can maintain translation when affected by the third driving structure 233. When the locking card plate 341 is in the slot of the fixing block 342, the third spring 3452 is in a compressed state and stores elastic potential energy. The resistance when the locking card plate 341 moves out of the slot is large, and the third spring 3452 can release elastic potential energy in this process. The force applied to the locking card plate 341 is consistent with the direction of the force provided by the third driving structure 233, thereby effectively sharing the workload of the third driving structure 233, making the entire unlocking process more efficient and smooth.

[0042] Reference Figure 4 and Figure 7 As shown: the limiting guide structure 345 also includes a mounting frame 3453 and a third guide rod 3454; one end of the mounting frame 3453 is connected to the lifting base 32; the third guide rod 3454 is vertically arranged, one end of the third guide rod 3454 is connected to the mounting frame 3453, and the other end of the third guide rod 3454 passes through the second guide rod 3451 and is slidably connected to the second guide rod 3451.

[0043] When the lifting base 32 is acted upon by the filling rope, it will move downward, and the locking card plate 341 cannot move due to the action of the fixing block 342, resulting in a close fit between the lifting base 32 and the locking card plate 341. At this time, the second guide rod will be acted upon by a force perpendicular to the axial direction, causing the second guide rod to bend, thereby affecting its guiding and supporting functions. By providing a third guide rod 3454, the third guide rod 3454 slidingly connects the second guide rod to the lifting base 32. The force perpendicular to the axial direction applied to the second guide rod will drive the second guide rod to move along the third guide rod 3454, thereby preventing the second guide rod from being bent due to the force, thereby ensuring the stability of the locking card plate 341 during movement.

[0044] Reference Figure 2 , Figure 8 and Fig. 9 As shown: the guide component 21 includes a rectangular frame 211, two clamping structures 212 and a first driving structure 213; the rectangular frame 211 is horizontally arranged, and the rectangular frame 211 is connected to the lifting component 22; the two clamping structures 212 are arranged inside the rectangular frame 211, and the clamping structure 212 includes a wheel frame 2121, a first roller 2122 and a plurality of second rollers 2123, the wheel frames 2121 in the two clamping structures 212 are parallel to each other, the first roller 2122 is arranged on the upper half of the wheel frame 2121, and the plurality of second rollers 2123 are arranged at equal intervals on the lower half of the wheel frame 2121; the first driving structure 213 is arranged on one side of the rectangular frame 211, and the first driving structure 213 is connected to the two clamping structures 212.

[0045] The filling rope is made of flexible material. When switching the filling rope, it is necessary to transfer the filling rope and connect it to another filling rope. At this time, the filling rope will be clamped, which may easily cause deformation of the filling rope. Therefore, a first roller 2122 and several second rollers 2123 are set in the clamping structure 212. The filling rope is S-shaped between the several second rollers 2123 in the two clamping structures 212, and enters the cable production line from between the two first rollers 2122. Since the filling rope is in contact with the several second rollers 2123 at the same time, when the first driving structure 213 drives the two clamping structures 212 to clamp the filling rope, the several second rollers 2123 in the two clamping structures 212 approach each other, and the several second rollers 2123 are in contact with the filling rope at the same time. The several second rollers 2123 apply force to the filling rope at the same time, so that the distribution range of the force on the filling rope is increased, thereby effectively dispersing the stress generated in the clamping process and avoiding large deformation of the filling rope due to concentrated force.

[0046] Reference Fig. 9 and Fig.10 As shown: the first driving structure 213 includes two first guide rods 2131, two first moving blocks 2132, two first springs 2133, a U-shaped push plate 2134 and a linear driver 2135; the two first guide rods 2131 are arranged in parallel, and the two ends of the first guide rods 2131 are connected to the rectangular frame 211; the two first moving blocks 2132 are symmetrically arranged about the middle surface of the rectangular frame 211, the two ends of the first moving block 2132 are respectively slidably connected to the two first guide rods 2131, and the first moving block 2132 is connected to the clamping structure 212, and the two first springs 2133 are respectively sleeved on the two first guide rods 2131; the U-shaped push plate 2134 is arranged at the same end of the two first moving blocks 2132; the linear driver 2135 is arranged at one end of the rectangular frame 211, and the linear driver 2135 is connected to the U-shaped push plate 2134.

[0047] When it is necessary to clamp the filling rope, the linear drive 2135 pushes the U-shaped push plate 2134 to move, and the two ends of the U-shaped push plate 2134 contact the two first moving blocks 2132. As the U-shaped push plate 2134 gradually approaches the two first moving blocks 2132, the two first moving blocks 2132 approach each other, and the first spring 2133 between the two first moving blocks 2132 is compressed and stores elastic potential energy. When it is necessary to release the clamping of the filling rope, the linear drive 2135 drives the U-shaped push plate 2134 away from the two first moving blocks 2132, and cooperates with the elastic potential energy released by the first spring 2133 to make the two first moving blocks 2132 move away from each other, thereby realizing the synchronous movement of the two clamping structures 212, ensuring the uniform distribution of the clamping force, and improving the clamping accuracy and stability.

[0048] Reference Figure 2 , Fig.10 and Fig.11 As shown: the lifting assembly 22 includes a fixed seat 221, two lifting guide structures 222, a lifting plate 223 and a second driving structure 224; both sides of the fixed seat 221 are connected to the two discharge structures 3; the two lifting guide structures 222 are arranged at the upper end of the fixed seat 221, and the two lifting guide structures 222 are symmetrically arranged about the middle surface of the fixed seat 221, the lifting guide structure 222 includes a guide sleeve 2221 and a first guide column 2222, the lower end of the guide sleeve 2221 is connected to the fixed seat 221, and the first guide column 2222 is slidably arranged in the guide sleeve 2221; the lifting plate 223 is arranged at the upper end of the lifting guide structure 222, and the two ends of the lifting plate 223 are connected to the two lifting guide structures 222; the second driving structure 224 is arranged between the two lifting guide structures 222 The second driving structure 224 is connected to the middle part of the lifting plate 223. The second driving structure 224 includes a bracket 2241, a first driving plate 2242, two racks 2243, two first gears 2244 and two second gears 2245. The two ends of the bracket 2241 are respectively connected to the two guide sleeves 2221. The first driving plate 2242 is vertically arranged, and the top of the first driving plate 2242 is connected to the lifting plate 223. The two first racks 2243 are respectively arranged on both sides of the first driving plate 2242. The two first gears 2244 are respectively meshed with the two first racks 2243, and the first gear 2244 is connected to the bracket 2241. The two second gears 2245 are respectively coaxially arranged with the two first gears 2244, and the two second gears 2245 are meshed with each other.

[0049] When the filling rope is placed on the lifting base 32, the lifting base 32 descends, the height of the filling rope decreases, and the guide assembly 21 needs to descend to dock with the filling rope. At this time, the two mutually meshing second gears 2245 rotate, driving the two first gears 2244 to rotate in opposite directions. At this time, the two first gears 2244 respectively apply forces in the same direction to the two racks 2243, and the first driving plate 2242 moves under the combined force of the two racks 2243, and the combined force acts on the lifting plate 223. When the combined force applied to the lifting plate 223 is upward, the lifting plate 223 drives the two first guide posts 2222 to extend out of the guide sleeve 2221. The cooperation between the first guide post 2222 and the guide sleeve 2221 enables the lifting plate 223 to keep moving smoothly. When the combined force applied to the lifting plate 223 is downward, the lifting plate 223 moves downward. During the lifting process, the lifting plate 223 drives the guide assembly 21 to move, thereby realizing the adjustment of the height of the guide assembly 21.

[0050] Reference Figure 2 and Fig.12As shown: the guide structure 2 also includes a switching component 23, which is arranged on the lifting plate 223. The switching component 23 includes a rotating shaft 231, two swing arms 232, a third driving structure 233 and a counterweight 234; both ends of the rotating shaft 231 are connected to the lifting plate 223 through bearings; the two swing arms 232 are respectively arranged at both ends of the rectangular frame 211, one end of the swing arm 232 is fixedly connected to the rotating shaft 231, and the other end of the swing arm 232 is rotatably connected to the rectangular frame 211; the third driving structure 233 is arranged on the rotating shaft 231. One end of the shaft 231, and the third driving structure 233 is connected to the rotating shaft 231, the third driving structure 233 includes a third gear 2331, a fourth gear 2332 and a rotation driver 2333, the third gear 2331 is connected to the rotating shaft 231, the fourth gear 2332 is meshed with the third gear 2331, the rotation driver 2333 is arranged on the lifting plate 223, and the rotation driver 2333 is connected to the fourth gear 2332; the counterweight block 234 is arranged at one end of the swing arm 232 connected to the rectangular frame 211.

[0051] In the initial state, the switching component 23 is located between the two discharging structures 3 and is in a horizontal state. When the filling rope is placed on the lifting base 32, the lifting base 32 drives the filling rope to move downward, and then the switching component 23 works, the fourth rotation driver 2333 works, the fourth rotation driver 2333 drives the fourth gear 2332 to rotate, the fourth gear 2332 drives the third gear 2331 to rotate, the third gear 2331 drives the rotating shaft 231 to rotate 90 degrees, and the rotating shaft 231 drives the rectangular frame 211 to rotate through the two swing arms 232. At the same time, the rectangular frame 211 can remain horizontal under the action of the counterweight block 234, and the rotating shaft 231 transfers the rectangular frame 211 to the top of the filling rope, so as to facilitate the connection of the filling rope with the guide assembly 21. When a new filling rope needs to be switched, the fourth rotation driver 2333 drives the fourth gear 2332 to rotate in the opposite direction, and the fourth gear 2332 drives the rotating shaft 231 to rotate 180 degrees in the opposite direction through the third gear 2331, and rotates the guide assembly 21 to the top of the spare filling rope, thereby realizing the switching of the guide assembly 21 between the two discharge structures 3.
