DETAILED DESCRIPTION

[0032] In order to further understand the features, technical means and specific purposes and functions of the present application, the present application is described in detail below in combination with the drawings and specific embodiments.

[0033] REFERENCE Figures 1 to 12The utility model discloses a high -efficient PP filling rope pay -off device, including mobile base 1, guide structure 2 and two pay -off structure 3, guide structure 2 sets up in the middle part of mobile base 1, and guide structure 2 includes guide assembly 21 and lifting assembly 22, and guide assembly 21 sets up in the upper end of lifting assembly 22, and lifting assembly 22 sets up in the middle part of mobile base 1, two pay -off structure 3 are arranged respectively in the both sides of guide structure 2, and pay -off structure 3 includes vertical pay -off frame 31, lifting base 32, four reset guide structure 33 and locking structure 34, and the lower end of vertical pay -off frame 31 is connected with mobile base 1, and lifting base 32 is horizontally arranged in the inside of vertical pay -off frame 31, and four reset guide structure 33 are arranged respectively on the four corners of lifting base 32, and reset guide structure 33 includes second guide pillar 331 and second spring 332, and second guide pillar 331 is perpendicular to lifting base 32, and the both ends of second guide pillar 331 are connected with the upper and lower ends of vertical pay -off frame 31, and second spring 332 sets up in the lower end of lifting base 32, and second spring 332 is sleeved on second guide pillar 331, and the both ends of second spring 332 are respectively with the end of lifting base 32 and second guide pillar 331 abuts, and locking structure 34 sets up in the lower end of lifting base 32.

[0034] The packing size of the filling rope is larger, the filling rope can be continuously and uninterruptedly provided, the number of joints between the filling ropes in the cable is reduced, and the quality hidden danger of the cable product is reduced, but the packing height of the filling rope is higher, and it is not convenient to connect two filling ropes. Therefore, the discharging device is arranged. In the initial state, the locking structure 34 stably fixes the height of the lifting base 32, ensures the stable placement of the filling rope, then the operator places two filling ropes on the two lifting bases 32 respectively, then 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 exert downward pressure on the second spring 332, causing the second spring 332 to be compressed, thereby promoting the lifting base 32 to move downward along the second guide column 331 to reduce the height of the top of the filling rope. Then, the lifting assembly 22 is started and drives the guide assembly 21 to descend to adapt to the adjusted height of the filling rope. Then, the operator passes one end of one of the filling ropes through the guide assembly 21, so that it is smoothly connected into 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 below the lifting base 32 gradually decreases, promoting 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 fixed by the locking structure 34 again. At the same time, the second spring 332 below the lifting base 32 corresponding to the standby filling rope is compressed due to the weight of the filling rope, so that the top height of the standby filling rope is lowered, facilitating the operator to quickly and conveniently connect two filling ropes, thereby effectively reducing the time required for connecting the filling ropes and improving the overall production efficiency.

[0035] Referring to Figure 3 and Figure 4 As shown: the locking structure 34 includes two locking clamping plates 341, four fixed blocks 342 and a fourth driving structure 343; the two locking clamping plates 341 are symmetrically arranged about the middle of the lifting base 32; the four fixed blocks 342 are respectively arranged at the two ends of the two locking clamping plates 341, the opposite sides of the two fixed blocks 342 at the same end of the two locking clamping plates 341 are provided with clamping grooves, and the fixed blocks 342 are connected with the vertical discharging rack 31; the fourth driving structure 343 is arranged between the two locking clamping plates 341.

[0036] If the lifting base 32 is only supported by the second spring 332, when placing the filling rope, the filling rope may not be placed stably, and the lifting base 32 may move downward due to local stress, causing the filling rope to tilt. Therefore, in the initial state, the two ends of the locking clamping plate 341 abut against the end of the clamping groove of the two fixed blocks 342, preventing the locking clamping plate 341 from continuing to move upward. Then, the fourth driving structure 343 is started, the fourth driving structure 343 drives the two locking clamping plates 341 to move away from each other, and the two ends of the locking clamping plate 341 move into the clamping grooves of the two fixed blocks 342 at the same time. The clamping grooves limit the locking clamping plate 341 in the vertical direction, preventing the locking clamping plate 341 from moving downward. Therefore, the position of the lifting base 32 remains fixed, thereby enabling the filling rope to be stably placed on the lifting base 32, and achieving stable descent of the filling rope.

[0037] Referring to Figure 4 and Figure 5 illustrated: the fourth driving structure 343 includes two bidirectional lead screws 3431, two fifth gears 3432, and a sixth gear 3433. The two bidirectional lead screws 3431 are arranged in parallel between the two locking clamping plates 341. The two ends of each bidirectional lead screw 3431 are provided with a second moving block 3434, which is threadedly connected with the bidirectional lead screw 3431. One side of the second moving block 3434 is provided with a second driving plate 3435, and the two ends of the second driving plate 3435 are respectively connected with the second moving block 3434 and the middle part of the locking clamping plate 341. The two fifth gears 3432 are arranged at the same end of the two bidirectional lead screws 3431. The sixth gear 3433 is arranged between the two fifth gears 3432, and the sixth gear 3433 is engaged with the two fifth gears 3432.

[0038] 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, and the two fifth gears 3432 drive the two bidirectional lead screws 3431 to rotate, respectively. The two second moving blocks 3434 of the bidirectional lead screws 3431 move closer to each other, and the two second driving plates 3435 exert a pushing force on the locking clamping plate 341 towards the clamping groove, enabling the locking clamping plate 341 to be inserted into the clamping groove, thereby locking the lifting base 32. After the filling rope is stably placed on the lifting base 32, the sixth gear 3433 rotates reversely, driving the two bidirectional lead screws 3431 to rotate reversely through the two fifth gears 3432. The two second moving blocks 3434 of the bidirectional lead screws 3431 move away from each other, and the two second driving plates 3435 exert a pulling force on the locking clamping plate 341 away from the clamping groove. Since the two bidirectional lead screws 3431 rotate synchronously, the two locking clamping plates 341 move synchronously. Therefore, the lifting base 32 can simultaneously receive or lose the force exerted by the two locking clamping plates 341, thereby helping to maintain the stability of the lifting base 32 during the locking and releasing processes.

[0039] Referring to Figure 4 and Figure 6 The locking structure 34 further comprises four rolling assemblies 344, two of which are arranged at two ends of the locking plate 341 respectively, and each rolling assembly 344 comprises a mounting plate 3441 and a plurality of third rollers 3442 arranged at equal intervals on the mounting plate 3441.

[0040] When the filling rope is placed on the lifting base 32, the lifting base 32 is kept at a constant height by the cooperation of the locking plate 341 and the fixed block 342, but the force acting on the lifting base 32 is transmitted to the locking plate 341 and the fixed block 342, so that the friction between the locking plate 341 and the fixed block 342 is large, and when the locking plate 341 and the fixed block 342 need to be separated, a large resistance is encountered. By arranging the rolling assembly 344 at the end of the locking plate 341, the contact between the third roller 3442 and the fixed block 342 is rolling friction, which has a significantly lower friction coefficient than sliding friction. Therefore, under the action of the same force, the friction between the third roller 3442 and the fixed block 342 is much smaller than the friction generated when the locking plate 341 directly contacts the fixed block 342, thereby facilitating the movement of the locking plate 341 out of the fixed block 342.

[0041] Referring to Figure 3 , Figure 4 and Figure 7 The locking structure 34 further comprises two limiting guide structures 345, which are arranged on both sides of the two locking plates 341 respectively. The limiting guide structure 345 comprises a second guide rod 3451 which is perpendicular to the bidirectional screw rod 3431, one end of the second guide rod 3451 is connected with the lifting base 32, and the locking plate 341 is slidingly connected with the second guide rod 3451. A third spring 3452 is further sleeved on the second guide rod 3451, and the two ends of the third spring 3452 are respectively in abutment with the end of the second guide rod 3451 and the locking plate 341.

[0042] The second guide rod 3451 limits the movement of the locking plate 341, so that the locking plate 341 can keep translating when it is acted on by the third driving structure 233. When the locking plate 341 is in the clamping groove of the fixed block 342, the third spring 3452 is in a compressed state and stores elastic potential energy, and the resistance when the locking plate 341 moves out of the clamping groove is large. The third spring 3452 can release the elastic potential energy in this process, and the force acting on the locking plate 341 is consistent with the force provided by the third driving structure 233, thereby effectively sharing the working load of the third driving structure 233, making the entire unlocking process more efficient and smooth.

[0043] Referring to Figure 4 and Figure 7 As shown in The limiting and guiding structure 345 further comprises a mounting frame 3453 and a third guide rod 3454. One end of the mounting frame 3453 is connected with the lifting base 32. The third guide rod 3454 is vertically arranged, one end of the third guide rod 3454 is connected with the mounting frame 3453, and the other end of the third guide rod 3454 penetrates through the second guide rod 3451 and is in sliding connection with the second guide rod 3451.

[0044] When the lifting base 32 is subjected to the action force of the filling rope and moves downward, the locking clamping plate 341 cannot move under the action of the fixing block 342, so that the lifting base 32 and the locking clamping plate 341 are tightly attached to each other. At this time, the second guide rod will be subjected to an action force perpendicular to the axis direction, causing the second guide rod to bend and affecting its guiding and supporting functions. By arranging the third guide rod 3454, the third guide rod 3454 is in sliding connection between the second guide rod and the lifting base 32. The action force perpendicular to the axis direction of the second guide rod drives the second guide rod to move along the third guide rod 3454, thereby avoiding the bending of the second guide rod under stress and ensuring the stability of the locking clamping plate 341 during movement.

[0045] Referring to Figure 2 , Figure 8 and Figure 9 As shown in The guiding assembly 21 comprises a rectangular frame 211, two clamping structures 212 and a first driving structure 213. The rectangular frame 211 is horizontally arranged and connected with the lifting assembly 22. The two clamping structures 212 are arranged inside the rectangular frame 211. The clamping structure 212 comprises a wheel frame 2121, a first roller 2122 and a plurality of second rollers 2123. The wheel frames 2121 of the two clamping structures 212 are parallel to each other. The first roller 2122 is arranged at the upper half of the wheel frame 2121. The plurality of second rollers 2123 are arranged at the lower half of the wheel frame 2121 at equal intervals. The first driving structure 213 is arranged at one side of the rectangular frame 211 and connected with the two clamping structures 212.

[0046] The filling rope is a flexible material, and when the filling rope is switched, the filling rope needs to be connected with another filling rope, at this time the filling rope is clamped and is easy to deform, therefore, the first roller 2122 and the plurality of second rollers 2123 are arranged in the clamping structure 212, the filling rope is in an S shape between the plurality of second rollers 2123 in the two clamping structures 212 and enters the cable production line from between the two first rollers 2122, because the filling rope is in contact with the plurality of 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 plurality of second rollers 2123 in the two clamping structures 212 are close to each other, the plurality of second rollers 2123 are in contact with the filling rope at the same time, the plurality of second rollers 2123 simultaneously apply a force to the filling rope, so that the distribution range of the force acting on the filling rope increases, thereby effectively dispersing the stress generated in the clamping process and avoiding that the filling rope is deformed greatly due to stress concentration.

[0047] Referring to Figure 9 and Figure 10 , 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 rod 2131 are connected with 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 connected with the two first guide rods 2131 in a sliding manner, and the first moving block 2132 is connected with the clamping structure 212; 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; and the linear driver 2135 is arranged at one end of the rectangular frame 211 and connected with the U-shaped push plate 2134.

[0048] When the filling rope needs to be clamped, the linear driver 2135 pushes the U-shaped push plate 2134 to move, the two ends of the U-shaped push plate 2134 are in contact with 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 are close to each other, and the first spring 2133 between the two first moving blocks 2132 is compressed and stores elastic potential energy, when the clamping of the filling rope needs to be released, the linear driver 2135 drives the U-shaped push plate 2134 to move away from the two first moving blocks 2132, and cooperates with the elastic potential energy released by the first spring 2133, so that the two first moving blocks 2132 are away from each other, realizing the synchronous movement of the two clamping structures 212, ensuring the uniform distribution of the clamping force, and improving the clamping precision and stability.
