Description

Technical Field

[0001] This utility model relates to the field of winding device technology, and in particular to a PET sheet winding device. Background Technology

[0002] PET sheets are a new type of plastic product that has been developed in recent years. PET sheets have good ductility and plasticity, and are also environmentally friendly. PET sheets have good weather resistance, chemical stability, low water absorption, and are resistant to weak acids and organic solvents, but they are not resistant to hot water immersion or alkalis. Due to the large demand for PET sheets, after the sheets are extruded by the extruder, they are wound up on the winding rollers in the roll mill through the unfolding frame and traction machine for easy storage and handling.

[0003] Although a sheet winding machine in the prior art (publication number: CN213230801U) can effectively prevent the wound sheet from falling off due to excessive weight during the winding process through the placement device, after the winding machine completes the single roll winding process, it is necessary to remove the completed roll from the surface of the winding roller. Since the winding is tight, it is often not convenient to unload the material. Therefore, there is an urgent need to design a PET sheet winding device that is easy to unload. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a PET sheet winding device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] The winding assembly has two winding assemblies that are symmetrically installed in the main frame of the equipment, and the two winding assemblies alternately perform winding operations.

[0008] The support components are provided in two and are respectively disposed below the two winding components. Each support component is used to support the material during unloading to prevent it from shaking.

[0009] As a further embodiment of this utility model, the winding assembly includes a winding motor, a hydraulic telescopic rod, and a bracket. The bracket has a U-shaped structure and is fixedly installed on one side of the main frame of the equipment. The winding motor is fixedly installed at the bottom of the main frame of the equipment. The hydraulic telescopic rod is fixedly installed on one side of the bracket, and a main shaft is rotatably installed on the other side of the bracket.

[0010] As a further embodiment of this utility model, a slider is slidably installed inside the bracket, one end of the main shaft passes through the bracket and a pulley is sleeved on the arc surface near the end, a pulley is also fixedly installed at the output end of the winding motor, a transmission belt is sleeved between the two pulleys, one end of the main shaft has a cross-shaped through hole penetrating its outer surface, a movable shaft is slidably installed inside the through hole, one end of the movable shaft is rotatably connected to one side of the slider, and the other side of the slider is fixedly installed to the telescopic end of the hydraulic telescopic rod.

[0011] As a further embodiment of this utility model, the main shaft surface is provided with multiple adjustment mechanisms evenly arranged in a circular pattern. Each adjustment mechanism includes an active support rod, multiple driven support rods, multiple adapter blocks, and a movable blade. The multiple driven support rods are linearly and uniformly rotatably mounted on the main shaft surface. The other ends of the multiple driven support rods are rotatably connected to the multiple adapter blocks respectively. The active support rod is rotatably mounted on one end of the movable shaft. The other end of the active support rod is rotatably mounted to an adjacent adapter block. The movable blade has an arc plate-shaped structure and is fixedly mounted to the multiple adapter blocks.

[0012] As a further embodiment of this utility model, the support component includes a base, which is fixedly installed on one side of the main frame of the equipment. A sliding groove is provided on the top of the base, and a lifting support block is slidably installed in the sliding groove. A V-shaped groove is provided on the top of the lifting support block, and the bottom of the lifting support block has a downward-facing U-shaped structure.

[0013] As a further embodiment of this utility model, a push block is slidably installed on the top of the base, and the push block has an inclined surface for pushing on the side near the lifting support block. The lifting support block abuts against the inclined surface of the push block, and a connecting rod is fixedly installed on the other side of the push block. The other end of the connecting rod is fixedly installed to the bottom of the slider.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] By setting up a winding assembly, when the equipment is ready to wind up the sheet, the hydraulic telescopic rod is activated to drive the movable shaft to slide inside the main shaft, and then the active support rod lifts the movable blades. The sheet is then wound onto the surface of multiple movable blades. When unloading, the movable shaft is driven to slide in the opposite direction, which causes the multiple movable blades to retract toward the main shaft, so that the winding assembly and the wound sheet are automatically separated, improving the convenience of unloading the sheet after winding.

[0025] Reference Figures 1-5 A PET sheet winding device includes a main frame 1, which is welded from multiple profile tubes. A guide roller 2 is rotatably mounted on one side of the main frame 1. It also includes two winding assemblies 3, symmetrically installed within the main frame 1, which alternately perform winding operations. Two support assemblies 4 are also included, each positioned below one of the two winding assemblies 3. Each support assembly 4 is used to support the material during unloading to prevent it from shaking. Each winding assembly 3 includes a winding motor 301, a hydraulic telescopic rod 302, and a bracket 303. The bracket 303 has a U-shaped structure and is fixedly installed on one side of the main frame 1. The winding motor 301 is fixedly installed at the bottom of the main frame 1. The hydraulic telescopic rod 302 is fixedly installed on one side of the bracket 303. A main shaft 306 is rotatably mounted on the other side of the bracket 303. A slider 305 is slidably installed within the bracket 303. One end of the main shaft 306 passes through the bracket 303 and a pulley 3 is sleeved on its end arc surface. 07. A pulley 307 is also fixedly installed at the output end of the winding motor 301. A transmission belt 304 is sleeved between the two pulleys 307. One end of the main shaft 306 has a cross-shaped through hole penetrating its outer surface. A movable shaft 308 is slidably installed in the through hole. One end of the movable shaft is rotatably connected to one side of the slider 305. The other side of the slider 305 is fixedly installed to the telescopic end of the hydraulic telescopic rod 302. Multiple adjustment mechanisms are evenly arranged on the circumference of the surface of the main shaft 306. Each adjustment mechanism includes an active support rod 309. The system includes multiple driven support rods 310, multiple adapter blocks 311, and movable blades 312. The driven support rods 310 are linearly and uniformly rotatably mounted on the surface of the main shaft 306. The other end of each driven support rod 310 is rotatably connected to one of the adapter blocks 311. The active support rod 309 is rotatably mounted on one end of the movable shaft 308. The other end of the active support rod 309 is rotatably mounted to the adjacent adapter block 311. The movable blades 312 have an arc-shaped plate structure and are fixedly mounted to the multiple adapter blocks 311.

[0026] In use, by setting up the winding assembly 3, when the equipment is ready to wind up the sheet, the hydraulic telescopic rod 302 is activated to drive the movable shaft 308 to slide within the main shaft 306, thereby supporting the movable blades 312 through the active support rod 309, and then the sheet is wound onto the surface of multiple movable blades 312. When unloading, the movable shaft 308 is driven to slide in the opposite direction, thereby causing multiple movable blades 312 to retract towards the main shaft 306, so that the winding assembly 3 and the wound sheet are automatically separated, improving the convenience of unloading the sheet after winding. When the winding assembly 3 separates from the sheet, the support assembly 4 is raised synchronously to support the wound sheet, preventing it from shaking during the unloading process, thus improving the practicality of the equipment.

[0027] In this embodiment, the support component 4 includes a base 401, which is fixedly installed on one side of the main frame 1 of the equipment. A groove 403 is provided on the top of the base 401, and a lifting support block 404 is slidably installed in the groove 403. A V-shaped groove is provided on the top of the lifting support block 404, and the bottom of the lifting support block 404 has an inverted U-shaped structure with the opening facing downward. A push block 402 is slidably installed on the top of the base 401. A sloping surface for pushing is provided on the side of the push block 402 near the lifting support block 404. The lifting support block 404 abuts against the sloping surface of the push block 402. A connecting rod 5 is fixedly installed on the other side of the push block 402, and the other end of the connecting rod 5 is fixedly installed to the bottom of the slider 305.

[0028] In use, when the winding assembly 3 separates from the sheet, the slider 305 slides within the bracket 303, thereby moving the connecting rod 5. The connecting rod 5 then moves the push block 402 to slide on top of the base 401. The push block 402 lifts the lifting support block 404, which uses a groove at the top to support the rolled sheet and prevent it from shaking during the unloading process. The appropriate height of the push block 402 is selected according to the change in the outer diameter of the rolled sheet, so that the lifting support block 404 can fit more closely to the outer diameter of the sheet, further improving the stability of the equipment during unloading and facilitating better unloading of the rolled sheet.

[0029] As can be seen from the above description, the above embodiments of this utility model achieve the following technical effects: the extruder extrudes the sheet, which is then passed around the guide roller 2 by the traction machine and then wound on one of the winding components 3. Before winding, the hydraulic telescopic rod will drive the movable shaft 308 to slide and then lift up multiple movable blades 312. After winding is completed, the movable blades 312 are retracted to facilitate the unloading of the PET roll. By setting two winding components and two support components, winding can be carried out alternately, which improves the working efficiency of the equipment in winding the sheet.
