Description

Technical Field

[0001] This utility model relates to the field of textile roll forming equipment technology, and in particular to an automatic roll forming mechanism. Background Technology

[0002] In the production processes of textile, packaging, printing and related manufacturing industries, the winding mechanism plays a crucial role as the core equipment for achieving continuous material winding. It can not only efficiently wind raw materials or semi-finished products into regular rolls, but also provide great convenience for subsequent storage, transportation and further processing. The working performance and winding quality of the winding mechanism directly determine the tension, flatness and uniformity of the roll, all of which have a profound impact on the overall quality, appearance and end-user experience of the final product.

[0003] However, traditional winding mechanisms cannot flexibly adjust the compressive strength according to the thickness of the roll material, which makes it easy for thinner roll materials to become loose and misaligned when winding, while thicker roll materials may wrinkle and damage the material surface due to excessive compaction. It is difficult to meet the compaction and flatness requirements of roll materials of different thicknesses. Therefore, this application is made. Utility Model Content

[0004] To overcome the technical defects of the existing technology, this utility model provides an automatic unwinding winding mechanism, which has the technical characteristics of ensuring that the roll material remains compact and flat during the winding process and adapting to the compaction requirements of roll materials of different thicknesses.

[0005] The technical solution adopted by this utility model is: an automatic unwinding winding mechanism, including a frame, a telescopic cylinder hinged on the frame, a connecting plate hinged to the output end of the telescopic cylinder, the connecting plate being rotatably connected to the frame, a take-up shaft being snapped between the connecting plates, a rotating shaft being rotatably mounted on the frame, a motor for driving the rotating shaft being mounted on the frame, a fixing bolt being threaded onto the rotating shaft, the take-up shaft being connected to the rotating shaft through the fixing bolt, and a detachable compaction assembly being provided on the frame.

[0006] To ensure that the roll material remains compact and flat during winding and to avoid problems such as looseness and wrinkles, while adapting to the compaction requirements of roll materials of different thicknesses, this utility model improves upon the following: the detachable compaction component includes a moving rod and a limiting plate. The moving rod is inserted into the frame, and the upper end of the moving rod is provided with a limiting plate. A return spring is sleeved on the moving rod, and both ends of the return spring are fixedly connected to the limiting plate and the frame, respectively. The lower end of the moving rod is provided with a mounting base, and a rolling cylinder is provided on the mounting base.

[0007] To facilitate the disassembly, maintenance, and replacement of the roller burnishing cylinder, and to ensure its installation stability during operation and prevent axial movement, this utility model is improved by providing mounting holes on the mounting base. The roller burnishing cylinder is engaged with the mounting base through the mounting holes. Both ends of the roller burnishing cylinder are provided with connecting threads, and fixing nuts are threadedly connected to both ends of the roller burnishing cylinder. The fixing nuts are pressed tightly against the mounting base.

[0008] To buffer the vibration and impact force experienced by the fixing bolt during the rotation of the winding shaft, this utility model is improved by having a connecting spring sleeved on the fixing bolt, with both ends of the connecting spring rotatably connected to the rotating shaft and the fixing bolt, respectively.

[0009] To improve the connection strength and rotational flexibility of the hinged joint between the telescopic cylinder and the frame and connecting plate, this utility model is improved by providing a hinge seat on the frame and the connecting plate, and the telescopic cylinder is hinged to the frame and the connecting plate through the hinge seat.

[0010] In order to limit the rotation angle of the connecting plate, the present invention is improved by providing a limiting hole on the frame and a limiting rod on the connecting plate, wherein the limiting rod is slidably engaged with the limiting hole.

[0011] To simplify the assembly and disassembly process of the take-up shaft and the connecting plate, facilitate quick unwinding after winding, and ensure the radial positioning stability of the take-up shaft during rotation and winding, this utility model is improved by providing a U-shaped hole on the connecting plate, and the take-up shaft engaging with the U-shaped hole.

[0012] To achieve adjustable installation of the moving rod on the frame, facilitate adjustment of the height position of the rolling cylinder according to changes in the roll diameter, and ensure the verticality and stability of the moving rod after installation, this utility model is improved by providing a positioning hole on the frame, through which the moving rod is inserted into the frame.

[0013] The beneficial effects of this utility model are:

[0014] 1. This utility model, through a detachable compaction component, can ensure that the roll material remains tight and flat during the winding process, effectively avoiding looseness and wrinkles, and adapting to the compaction requirements of roll materials of different thicknesses. It can facilitate the disassembly, maintenance and replacement of the roller, while ensuring the installation stability of the roller during operation and preventing its axial movement.

[0015] 2. This utility model utilizes a telescopic cylinder, a connecting plate, a U-shaped groove, and a limiting hole. The telescopic cylinder, through its own telescopic movement, drives the connecting plate to rotate, thereby realizing the function of unwinding the rolled material. This process effectively improves the convenience of operation and work efficiency. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings:

[0023] like Figures 1-5 As shown, this embodiment provides an automatic unwinding winding mechanism, including a frame 1. A telescopic cylinder 2 is hinged to the frame 1, and a connecting plate 3 is hinged to the output end of the telescopic cylinder 2. The connecting plate 3 is rotatably connected to the frame 1. The telescopic cylinder 2 extends and retracts to drive the connecting plate 3 to rotate around the frame 1, thereby causing the take-up shaft 4 to disengage from the rotating shaft 5, realizing automatic unwinding. The take-up shaft 4 is clamped between the connecting plates 3. The rotating shaft 5 is rotatably mounted on the frame 1. A motor 6 for driving the rotating shaft 5 is mounted on the frame 1. A fixing bolt 7 is threadedly connected to the rotating shaft 5. The take-up shaft 4 and the rotating shaft 5 are connected by the fixing bolt 7. The motor 6 drives the rotating shaft 5 to rotate, and the rotating take-up shaft 4 rotates synchronously to realize the winding operation of the material. A detachable compaction component 8 is provided on the frame 1.

[0024] The detachable compaction assembly 8 includes a moving rod 801 and a limiting plate 802. The moving rod 801 is inserted into the frame 1. The upper end of the moving rod 801 is provided with the limiting plate 802. A return spring 803 is sleeved on the moving rod 801. The two ends of the return spring 803 are fixedly connected to the limiting plate 802 and the frame 1, respectively. The moving rod 801 is inserted into the frame 1 through the positioning hole 14. The upper limiting plate 802 limits the return spring 803. The two ends of the return spring 803 are fixedly connected to the limiting plate 802 and the frame 1, respectively. The lower end of the moving rod 801 is provided with a mounting base 804. The mounting base 804 is provided with a rolling cylinder 805. The mounting base 804 has a mounting hole 806. As the material roll diameter increases, the reaction force of the rolling cylinder 805 on the material also increases. This force will drive the moving rod 801 to slide slowly upward along the positioning hole 14. At the same time, the return spring 803... The 03 is synchronously compressed, dynamically adapting to changes in material through its elastic deformation, thereby flexibly adjusting the pressure strength. This ensures that regardless of changes in the thickness of the roll, just the right pressure can be applied, neither excessive nor insufficient, effectively preventing the roll from becoming loose and wrinkled, guaranteeing the quality and stability of the roll, and improving overall work efficiency and product consistency. The rolling cylinder 805 is engaged with the mounting base 804 through the mounting hole 806. Both ends of the rolling cylinder 805 are provided with connecting threads, and both ends of the rolling cylinder 805 are threadedly connected to fixing nuts 807. The fixing nuts 807 are pressed tightly against the mounting base 804. The two ends of the rolling cylinder 805 are threadedly connected to the fixing nuts 807 through connecting threads. The fixing nuts 807 tightly press against both sides of the mounting base 804 to achieve axial limitation of the rolling cylinder 805, preventing axial movement during high-speed rotation and ensuring installation stability.

[0025] A connecting spring 9 is sleeved on the fixing bolt 7. The two ends of the connecting spring 9 are rotatably connected to the rotating shaft 5 and the fixing bolt 7, respectively. The connecting spring 9 can buffer the force between the fixing bolt 7 and the rotating shaft 5 to ensure connection stability. The frame 1 and the connecting plate 3 are provided with hinge seats 10. The telescopic cylinder 2 is hinged to the frame 1 and the connecting plate 3 through the hinge seats 10. The frame 1 has a limit hole 11. When the telescopic cylinder 2 is activated, the telescopic cylinder 2 extends and retracts, driving the connecting plate 3 to rotate around the frame 1, which drives the take-up shaft 4 to disengage from the rotating shaft 5, realizing automatic unwinding. The connecting plate 3 is provided with a limit rod 12, which slides and engages with the limit hole 11. At the same time, the limit rod 12 slides along the limit hole 11. The connecting plate 3 has a U-shaped hole 13, which engages with the take-up shaft 4. The frame 1 has a positioning hole 14, and the moving rod 801 is inserted into the frame 1 through the positioning hole 14.

[0026] Working principle: After the motor 6 starts, it drives the rotating shaft 5 to rotate. The fixing bolt 7 securely connects the take-up shaft 4 to the rotating shaft 5 under the action of the thread, so that the take-up shaft 4 rotates synchronously with the rotating shaft 5 to realize the winding operation. The telescopic cylinder 2 is hinged to the frame 1 and the connecting plate 3 through the hinge seat 10. Its telescopic movement can drive the connecting plate 3 to rotate around the frame 1. The limiting rod 12 on the connecting plate 3 slides along the limiting hole 11 of the frame 1 to ensure smooth rotation. At the same time, the take-up shaft 4 is engaged in the U-shaped hole 13 of the connecting plate 3 and adjusts its position with the rotation of the connecting plate 3 to adapt to the winding requirements. In the detachable compaction component 8, the moving rod 801 is inserted into the frame 1 through the positioning hole 14. The limiting plate 802 limits the vertical displacement range of the moving rod 801. The mounting base 804 is connected to the rolling cylinder 805 through the mounting hole 806. After the fixing nuts 807 at both ends of the rolling cylinder 805 are tightened, it is pressed and fixed to the mounting base 804. During the winding process, the rolling cylinder 805 is in contact with the surface of the rolled material and uses its own rotation to compact the rolled material to prevent the rolled material from loosening. The connecting spring 9 on the fixing bolt 7 is rotatably connected to the rotating shaft 5 and the fixing bolt 7 at both ends, which can buffer the vibration generated during the winding process and ensure the connection stability. After the winding is completed, the rolling cylinder 805 can be removed by loosening the fixing nut 807. Loosening the fixing bolt 7 can separate the take-up shaft 4 from the rotating shaft 5. The telescopic cylinder 2 retracts and drives the connecting plate 3 to rotate, making it easy to take out the finished rolled material on the take-up shaft 4 and realize the automatic unwinding function.

Those skilled in the art should understand that this invention is not limited to the above embodiments.
