Detailed Implementation

[0028] To make the technical means, creative features, achieved objectives and functions of this utility model clearer and easier to understand, the utility model will be further described below with reference to the accompanying drawings and specific embodiments:

[0029] like Figure 1As shown, this utility model proposes a winding device for a plastic extrusion production line, including: a winding device 1, a clamping device 2, and a conveying device 3. The winding device 1 includes: a winding frame 11, a servo motor 12, a pressing mechanism 13, and a winding mechanism 14. The servo motor 12 is mounted on the winding frame 11, and the winding mechanism 14 is mounted on the output end of the servo motor 12. The winding mechanism 14 is rotatably mounted on the winding frame 11 and can be driven to rotate by the output end of the servo motor 12. A plastic roll 15 is placed on the winding mechanism 14. The pressing mechanism 13 is mounted on one side of the winding frame 11, and the output end of the pressing mechanism 13 can press the outer layer of the plastic roll 15 onto the winding mechanism 14. A conveying device 3 is provided on one side of the winding frame 11. The conveying device 3 includes: a guide rail 31, a movable bearing device 32, a blocking mechanism 33, and an upward guiding component. 34. The guide rail 31 is installed below the winding mechanism 14. The movable carrier device 32 is slidably connected to the guide rail 31. The blocking mechanism 33 is installed at the end of the guide rail 31 away from the winding frame 11. The blocking mechanism 33 can prevent the movable carrier device 32 from sliding off the guide rail 31. The upward guide component 34 is located at the end of the guide rail 31 away from the winding frame 11. The upward guide component 34 is used to guide the bottom of the movable carrier device 32 onto the guide rail 31. The upward guide component 34 is installed next to the blocking mechanism 33. A clamping device 2 is installed above the movable carrier device 32. The clamping device 2 includes: a base 21, a mounting rod 22 and a supporting clamping mechanism 23. The base 21 is connected to the top of the movable carrier device 32 through the mounting rod 22. The clamping mechanism is installed above the base 21. The output end of the clamping mechanism is used to support and clamp the plastic roll 15.

[0030] During operation, the servo motor 12 drives the winding mechanism 14 to rotate, thereby winding the plastic roll 15. The clamping mechanism 13 presses the outer layer of the plastic roll 15 onto the winding mechanism 14 to ensure tight winding. After the plastic roll 15 is wound up, it is removed from the winding mechanism 14 and placed on the clamping device 2, where it is clamped. The movable carrier device 32 slides on the guide rail 31 to transport the plastic roll 15 to the unloading area for material collection. The blocking mechanism 33 prevents the carrier device from sliding out of the guide rail 31, thus achieving stable conveying and collection of the plastic roll 15. When the clamping device 2 needs maintenance or inspection, the blocking mechanism 33 can be adjusted to allow the carrier device to slide out of the guide rail 31 from the upward guide component 34.

[0031] like Figure 2As shown, the support and clamping mechanism 23 includes: a support plate 231, a support plate 232, a mounting plate 233, a rotating shaft 234, a clamping arm 235, and an adjusting mechanism 236. There are at least two support plates 232, which are mounted on the support plate 231. The two support plates 232 are used to support the plastic roll 15. The mounting plates 233 are mounted at both ends of the base 21. A rotating shaft 234 is provided between the two mounting plates 233. There are two rotating shafts 234, which are located on both sides of the base 21 respectively. The rotating shafts 234 can rotate relative to the mounting plates 233. A clamping arm 235 is mounted on the rotating shaft 234. The clamping arm 235 cannot rotate relative to the rotating shaft 234. The end of the rotating shaft 234 away from the winding mechanism 14 is connected to the adjusting mechanism 236. The adjusting mechanism 236 is used to adjust the clamping or opening of the clamping arm 235 on the rotating shaft 234. A support plate 232 is mounted on a support plate 231 and forms at least two support points for stably supporting the bottom of the plastic roll 15. Mounting plates 233 are fixed to both ends of a base 21. Two rotating shafts 234 are provided between the two mounting plates 233, located on both sides of the base 21, and the rotating shafts 234 can rotate relative to the mounting plates 233. Clamping arms 235 are mounted on the rotating shafts 234. The clamping arms 235 are mechanically fixed to the rotating shafts 234 and cannot rotate relative to the rotating shafts 234. The clamping and releasing of the clamping arms 235 are achieved by controlling the adjusting mechanism 236 to rotate the rotating shafts 234.

[0032] The adjustment mechanism 236 includes: a first linkage block 2361, a mounting shell 2362, a first linkage shaft 2363, and a telescopic adjustment rod 2364. The first linkage block 2361 is located on the side of the mounting plate 233 away from the clamping arm 235. The first linkage block 2361 has a first linkage hole and a second linkage hole. Each rotating shaft 234 is rotatably connected to the first linkage hole at one end away from the clamping and winding mechanism 14, and rotatably connected to one end of the first linkage shaft 2363 at the second linkage hole. The other end of the first linkage shaft 2363 is rotatably mounted on the mounting shell 2362. There are two of each of the first linkage block 2361, mounting shell 2362, and first linkage shaft 2363. Each set of the first linkage block 2361, mounting shell 2362, and first linkage shaft 2363 is mounted on a rotating shaft 234. The two mounting shells 2362 are connected by the telescopic adjustment rod 2364. When the opening and closing degree of the clamping arm 235 needs to be adjusted, the distance between the two mounting shells 2362 is adjusted by adjusting the adjusting rod. Since there are two of each of the first linkage block 2361, mounting shell 2362, and first linkage shaft 2363, all mounted on a rotating shaft 234, the extension and retraction of the adjusting rod will cause the two mounting shells 2362 to move closer or further apart, thereby driving the rotating shaft 234 to rotate through the first linkage shaft 2363 and the first linkage block 2361. The rotation of the rotating shaft 234, in turn, causes the clamping arm 235 to rotate around its axis, realizing the opening or clamping action of the clamping arm 235. This structure makes the opening and closing action of the clamping arm 235 more precise and stable, can adapt to plastic rolls 15 of different sizes, and ensures its stability during winding, transfer, and conveying processes.

[0033] The telescopic adjusting rod 2364 includes a threaded rod 241, a threaded sleeve 242, and a connecting block 243. One end of the threaded rod 241 is connected to a mounting housing 2362, and the other end of the threaded rod 241 is threadedly connected to one end of the threaded sleeve 242. The other end of the threaded sleeve 242 is rotatably mounted on another mounting housing 2362 via the connecting block 243. By rotating the threaded rod 241, the threaded sleeve 242 moves along the thread direction due to the threaded connection between the threaded rod 241 and the threaded sleeve 242. The movement of the threaded sleeve 242 drives the other mounting housing 2362 to move accordingly via the connecting block 243, thereby adjusting the distance between the two mounting housings 2362 to ensure that the clamping arm 235 can adapt to different specifications of plastic rolls 15, achieving stable clamping or release.

[0034] like Figure 3As shown, the mobile support device 32 includes: a support base 321, a sliding housing 322, a roller 323, a second linkage shaft 324, a main gear 325, a driven gear 326, and a travel drive motor 327. The top of the support base 321 is connected to the mounting rod 22. A sliding housing 322 is mounted on each side of the bottom of the support base 321. A roller 323 and a second linkage shaft 324 are provided between the two sliding housings 322. There are two sets of rollers 323 and second linkage shafts 324. The rollers 323 are slidably connected to the guide rail 31. The two rollers 323 are connected by the second linkage shaft 324. A mounting block protrudes downward from the bottom of the support base 321. A travel drive motor 327 is provided on one side of the mounting block. A main gear 325 is mounted on the output end of the drive motor. The driven gear 326 is mounted on the second linkage shaft 324 between the two rollers 323. The main gear 325 and the driven gear 326 mesh. When the walking drive motor 327 starts, its output end drives the main gear 325 to rotate. The main gear 325 meshes with the driven gear 326, thereby driving the driven gear 326 to rotate and driving the roller 323 to roll on the guide rail 31 to realize the conveying of the plastic roll 15.

[0035] The bottom of the guide rail 31 is provided with a support frame 4, which is located between the two guide rails 31. The blocking mechanism 33 includes: a stop block 331, a linkage rod 332, a fixed seat 333, a lifting block 334, and a spring 335. The fixed seat 333 is installed in the middle of the support frame 4. A lifting groove is opened in the middle of the fixed seat 333. A spring 335 is installed at the bottom of the lifting groove. The top of the spring 335 is connected to the lifting block 334. The lifting block 334 can rise and fall under the guidance of the fixed seat 333. A linkage rod 332 is provided on the lifting block 334. The two ends of the linkage rod 332 are connected to the stop block 331. The guide rail 31 has a slot 336 for the stop block 331 to retract. The stop block 331 is used to prevent the movable bearing device 32 from disengaging from the guide rail 31. When the movable support device 32 moves along the guide rail 31 to the end of the guide rail 31, the stop block 331 extends out of the slot 336 of the guide rail 31 under the elastic force of the spring 335, blocking the movable support device 32 from continuing to move forward and preventing it from derailing. When release is required, the lifting block 334 is pressed down by force, and the stop block 331 is driven to retract into the slot 336 through the linkage rod 332, so that the movable support device 32 can pass smoothly.

[0036] The upward guide component 34 is a pad 341, the top surface of which is arc-shaped and tangent to the top surface of the guide rail 31. When the mobile support device 32 moves to the end of the guide rail 31, its bottom smoothly transitions along the arc-shaped surface of the pad 341, successfully entering the guide rail 31, achieving automatic guidance and positioning, and improving the stability of the mobile support device 32 when entering the guide rail 31.

[0037] The winding mechanism 14 includes: a support block 141, a mounting plate 142, a blocking arm 143, and a connecting arm 144. At least three support blocks 141 are provided, forming a ring structure. A plastic roll 15 surrounds the support blocks 141. The support blocks 141 are connected to the mounting plate 142 via the connecting arm 144. The output end of the servo motor 12 passes through the mounting plate 142, which is fixed to the output end of the servo motor 12 by a nut. The mounting plate 142 can rotate relative to the servo motor 12. At least two blocking arms 143 are connected to the outer wall of the support block 141 to prevent the plastic roll 15 from detaching from the support block 141. The plastic roll 15 is placed on the support block 141, and the plastic material is wound up during rotation. The blocking arm 143 connected to the outer wall of the support block 141 blocks the radial movement of the plastic roll 15 during rotation, preventing it from detaching from the support block 141 due to centrifugal force, ensuring that the plastic roll 15 is stably and evenly wound on the support block 141, and completing an efficient winding operation.

[0038] The clamping mechanism 13 includes an upper clamping assembly 131 and a lower clamping assembly 132. Both the upper clamping assembly 131 and the lower clamping assembly 132 include a positioning plate 1311, a second linkage block 1312, a cylinder 1313, a rotating rod 1314, a clamping arm 1315, and a pressure roller 1316. The cylinder 1313 is mounted on one side of the winding frame 11, and the positioning plate 1311 is mounted beside the cylinder 1313 and connected to the winding frame 11. The output end of the cylinder 1313 is hinged to the second linkage block 1312. At one end of 12, the rotating rod 1314 passes through the other end of the second linkage block 1312. The second linkage block 1312 cannot rotate relative to the rotating rod 1314. The rotating rod 1314 is fixed to one end of the clamping arm 1315. The other end of the clamping arm 1315 is connected to a rolling pressure roller 1316, which is used to press the surface of the plastic roll 15. The clamping arm 1315 of the upper clamping assembly 131 is used to surround the upper side of the plastic roll 15, and the clamping arm 1315 of the lower clamping assembly 132 is used to surround the lower side of the plastic roll 15. When the cylinder 1313 is started, the extension and retraction action of its output end drives the second linkage block 1312 to move along the rotating rod 1314. Since the rotating rod 1314 is fixed to one end of the clamping arm 1315, the movement of the second linkage block 1312 will drive the clamping arm 1315 to rotate around the rotating rod 1314, thereby causing the pressure roller 1316 at the other end of the clamping arm 1315 to move closer to or away from the surface of the plastic roll 15. The clamping arm 1315 of the upper clamping assembly 131 surrounds the upper side of the plastic roll 15, and the pressure roller 1316 presses down on the top of the plastic roll 15; the clamping arm 1315 of the lower clamping assembly 132 surrounds the lower side of the plastic roll 15, and the pressure roller 1316 presses up on the bottom of the plastic roll 15. Through the precise control of the cylinder 1313, the pressure roller 1316 can apply a uniform clamping force to the plastic roll 15, ensuring the tightness and stability of the plastic roll 15 during the winding process and preventing loosening or deformation.
