Description

Technical Field

[0001] This application relates to the field of rewinding machine technology, and more particularly to a dual-core optional rewinding device. Background Technology

[0002] A rewinding machine is a specialized piece of equipment used to rewind large rolls of material into smaller rolls or to adjust the roll diameter. Among them, the dual-core selectable rewinding device is a specialized piece of equipment that can switch between two rewinding modes: with core and without core. It is widely used in the slitting and rewinding of roll materials such as paper, film, and mica tape.

[0003] A rewinding device is designed in the related technology, including an upper rewinding roller, a lower rewinding roller, and a core tube holder for conveying the core tube. The rewinding device has two working modes: a cored mode and a coreless mode. In the cored mode, the gap between the upper and lower rewinding rollers is larger, which can accommodate the core tube. At this time, the end of the core tube holder is located in the gap between the two rollers for conveying the core tube. In the coreless mode, the gap between the upper and lower rewinding rollers is smaller for coreless rewinding. However, when switching between the cored and coreless modes, the core tube holder needs to be disassembled and reassembled. Repeated disassembly and reassembly of the core tube holder not only affects the working efficiency of the rewinding machine, but also easily causes damage to the core tube holder, affecting its service life. Therefore, it needs to be improved. Utility Model Content

[0020] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0021] This application discloses a dual-core optional rewinding device. (Refer to...) Figure 1 and Figure 2The system includes a frame 1, which includes a base 11 and side panels 12 disposed on both sides of the base 11. A conveying mechanism 2 is disposed on the surface of the base 11. In this embodiment, the conveying mechanism 2 can be a belt conveyor. One end of the conveying mechanism 2 is connected to a core tube frame 3 for conveying the core tube. A positioning frame 4 is disposed on the side of the core tube frame 3 away from the conveying mechanism 2. A central rewinding roller 41 is rotatably connected to the positioning frame 4. An adjusting frame 5 is disposed on the side of the positioning frame 4 away from the core tube frame 3. A horizontal support arm 51 and an inclined support arm 52 are disposed on the adjusting frame 5. An upper rewinding roller 53 is rotatably connected to arm 51. The upper rewinding roller 53 is located above the central rewinding roller 41, and the gap between the two is small, so as to carry out coreless rewinding operations. A lower rewinding roller 54 is rotatably connected to inclined support arm 52. The lower rewinding roller 54 is located obliquely below the central rewinding roller 41, and the gap between the two is used to carry out cored rewinding operations. The end of the core tube frame 3 away from the conveying mechanism 2 is arc-shaped. The arc-shaped end of the core tube frame 3 is located between the central rewinding roller 41 and the lower rewinding roller 54, so as to carry out core tube conveying.

[0022] Reference Figure 3 and Figure 4 The core tube frame 3 includes a fixed end 31 and an extended end 32. The fixed end 31 is connected to the conveying mechanism 2. An adjustment groove 311 is provided on the side wall of the fixed end 31 near the positioning frame 4 for the extended end 32 to slide into. An adjustment member 312 is provided in the adjustment groove 311. In this embodiment, the adjustment member 312 adopts a small electric telescopic device, whose piston rod is connected to the extended end 32 to drive the extended end 32 to slide along the adjustment groove 311, thereby changing the position of the extended end 32. The arc-shaped part of the core tube frame 3 is provided on the extended end 32, thereby enabling the adjustment of the position of the arc-shaped part.

[0023] Reference Figure 3 and Figure 4 The extended end 32 has a relief groove 321 on its surface, and a plurality of pads 322 are provided in the relief groove 321. An elastic element 323 is provided between the bottom wall of each pad 322 and the bottom wall of the relief groove 321. In this embodiment, the elastic element 323 is a spring. After the pad 322 follows the extended end 32 out of the adjustment groove 311, the pad 322 pops out under the action of the elastic element 323, so that the surface of the pad 322 is flush with the surface of the fixed end 31, thereby maintaining the normal movement of the core tube. In this embodiment, in order to facilitate the pad 322 to enter the adjustment groove 311, a relief slope 324 is provided on the side wall of the pad 322 near the adjustment groove 311. Similarly, the opening of the adjustment groove 311 is provided with the same slope so that the pad 322 can enter the adjustment groove 311.

[0024] Reference Figure 1 , Figure 2 and Figure 5Based on the position adjustment of the core tube frame 3, the central rewinding roller 41 and the lower rewinding roller 54 also need to be adjusted accordingly to meet the rewinding operation of core tubes with different diameters. Therefore, the positioning frame 4 is provided with a first adjustment component 6 for adjusting the central rewinding roller 41 on both sides, and the adjustment frame 5 is provided with a second adjustment component 7 for adjusting the lower rewinding roller 54 on both sides.

[0025] Reference Figure 1 , Figure 2 and Figure 5 The first adjustment component 6 includes an adjustment plate 61, an adjustment sleeve 62, an adjustment screw 63, and an adjustment motor 64. A lifting groove 42 is provided through the side wall of the positioning frame 4 in the rearward direction. The lifting groove 42 is opened along the height direction of the positioning frame 4. The connecting shaft at the end of the central rewinding roller 41 passes through the lifting groove 42. The adjustment plate 61 is set on the outer wall of the positioning frame 4. The connecting shaft at the end of the central rewinding roller 41 is rotatably connected to the adjustment plate 61. The adjustment sleeve 62 is set on the top wall of the adjustment plate 61. The adjustment motor 64 is set on the side wall of the positioning frame 4. The adjustment screw 63 is connected to the output shaft end of the adjustment motor 64. The adjustment screw 63 is inserted into the adjustment sleeve 62 and threadedly engaged with the adjustment sleeve 62. The side wall of the positioning frame 4 is provided with a limiting shaft 43. The adjustment plate 61 is provided through the thickness direction with a limiting groove 611 for the limiting shaft 43 to pass through. Under the action of the first adjustment component 6, the central rewinding roller 41 can move up and down in the vertical direction.

[0026] Reference Figure 1 , Figure 2 and Figure 5 The second adjustment component 7 includes a sliding block 71 and two electric telescopic rods 72. The inner wall of the adjustment frame 5 is provided with a sliding groove 55 for the sliding block 71 to be set and slide. The sliding groove 55 is opened in the horizontal direction. The inclined support arm 52 is connected to the sliding block 71. Both electric telescopic rods 72 are set in the sliding groove 55. The sliding block 71 is located between the two electric telescopic rods 72. The piston rod of the electric telescopic rod 72 is connected to the sliding block 71. Under the action of the second adjustment component 7, the lower rewinding roller 54 can perform horizontal adjustment movement.

[0027] Reference Figure 1 and Figure 2 Since the central rewinding roller 41 can be adjusted up and down, when the central rewinding roller 41 moves upward, the upper rewinding roller 53 needs to make some room. Therefore, the horizontal support arm 51 includes a main body section 511 and a rotating section 512. The main body section 511 is connected to the adjusting frame 5, and the rotating section 512 is rotatably connected to the end of the main body section 511 away from the adjusting frame 5. A rotating component 513 is provided at the rotatable connection between the rotating section 512 and the main body section 511. The upper rewinding roller 53 is rotatably connected to the end of the rotating section 512 away from the main body section 511. In this embodiment, the rotating component 513 is a motor.

[0028] Reference Figure 1 and Figure 2 To maintain the operational stability of the upper rewinding roller 53, the center rewinding roller 41, and the lower rewinding roller 54, the surrounding plate 12 is provided with a track groove 121 through the thickness direction for the connecting shafts of the upper rewinding roller 53, the center rewinding roller 41, and the lower rewinding roller 54 to pass through and slide.

[0029] The implementation principle of the dual-core selectable rewinding device in this application embodiment is as follows: This application can select appropriate rewinding rollers for rewinding operations according to the working mode. When a coreless mode is required, the upper rewinding roller 53 and the center rewinding roller 41 are selected. When a cored mode is required, the center rewinding roller 41 and the lower rewinding roller 54 are selected. At the same time, the core tube frame 3, the center rewinding roller 41 and the lower rewinding roller 54 of this application can be flexibly adjusted in position based on the diameter of the core tube to adapt to the rewinding operation of core tubes of different specifications.

[0030] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
