Description

Technical Field

[0001] The utility model relates to the technical field of white cardboard rolling equipment, in particular to a rolling equipment for white cardboard. Background Art

[0002] White cardboard refers to single- or multi-layer paper made entirely from bleached chemical pulp and fully sized, suitable for printing and product packaging. After production, white cardboard typically requires a winder to be wound into a roll for subsequent transportation and transfer. Current white cardboard winders utilize a detachable winding roller connected to a motor that drives its rotation. One end of the white cardboard is then secured to the side of the winding roller by bonding or other means. The motor then drives the winding roller to rapidly rotate, forming a roll of white cardboard. Finally, the winding roller is removed to remove the roll for subsequent winding. However, in actual operation, these winders are limited in the radius of the roll that can be wound each time, as the winding roller can only be mounted at a fixed height on the winding frame. This makes them incapable of adapting to the needs of winding rolls with larger radii. Furthermore, the motor and winding roller are typically connected by a coupling, making manual assembly and disassembly of the winding roller time-consuming and labor-intensive. This results in long winder setup times and low winding efficiency. Utility Model Content

[0020] The following will clearly and completely describe the technical solutions of the present invention in conjunction with specific embodiments. Obviously, the embodiments described are only some of the embodiments of the present invention, and not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0021] Example: A winding device for white cardboard, such as Figure 1-3 As shown, it includes a pair of triangular frames 1 that are parallel to each other and spaced apart and in the shape of a right triangle, a pair of sliders 2 that are respectively slidably arranged on the oblique sides of the two triangular frames 1, two groups of driving components 3 that respectively drive the two sliders 2 to slide along the oblique sides of the triangular frame 1, a pair of U-shaped support seats 4 that are respectively fixed on the two sliders 2, winding rollers 5 that are movably placed on the middle parts of the two U-shaped support seats 4 at both ends, a pair of sprockets 6 that are rotatably arranged on one side of the triangular frame 1, a chain 7 that is sleeved on the two sprockets 6 and parallel to the oblique sides of the triangular frame 1, a sprocket 8 that is fixed to one end of the winding roller 5 and engages with the chain 7, and a motor 9 that drives the sprocket 6 to rotate. The motor 9 is fixedly installed on the side of the triangular frame 1 away from the sprocket 6, and the output end of the motor 9 rotates through the triangular frame 1 to connect with the sprocket 6.

[0022] Furthermore, the triangular frame 1 includes an L-shaped bracket 11 and a pair of support plates 12 spaced parallel to each other. The upper and lower ends of the support plates 12 are fixedly connected to the upper and lower ends of the L-shaped bracket 11, respectively. The slider 2 is slidably arranged between the gaps of the two support plates 12. The sprocket 6 and the motor 9 are respectively located on the opposite sides of the two support plates 12, and the output end of the motor 9 rotates through the two support plates 12 to connect to the sprocket 6. By adopting the above-mentioned triangular frame 1 structure, not only is welding and assembly manufacturing convenient, but it also provides sufficient installation and movement space for the various components of the drive assembly 3. Among them, a connecting rod 11a is fixedly connected between the two L-shaped brackets 11, and the connecting rod 11a is located at the corner of the two L-shaped brackets 11, which can further ensure the stability of the structure of the two triangular frames 1 and provide good support for the winding roller 5.

[0023] Furthermore, a pair of connecting plates 12a are fixedly connected between the two support plates 12, and the two connecting plates 12a are parallel to each other and respectively close to the upper and lower ends of the support plate 12, and the slider 2 is located between the two connecting plates 12a and slides; the driving assembly 3 includes a screw rod 31 whose two ends are respectively rotatably connected to the two connecting plates 12a and pass through the slider 2, a nut 32 fixed on the slider 2 and threadedly connected to the screw rod 31, a worm gear 33 fixedly installed at one end of the screw rod 31, a worm 34 rotatably arranged between the two support plates 12 and meshing with the worm gear 33, and a second motor 35 that drives the worm 34 to rotate, the screw rod 31 and the parallel are located in the middle of the two support plates 12, the worm gear 33 and the slider 2 are located on both sides of a connecting plate 12a, and the lower end of the screw rod 31 rotates through the connecting plate 12a to connect to the worm gear 33, the second motor 35 and the worm 34 are respectively located on both sides of a support plate 12, and the output end of the second motor 35 rotates through the support plate 12 to connect one end of the worm 34.

[0024] By adopting the above-mentioned drive assembly 3, not only can the slider 2 be effectively driven to slide along the middle of the support plate 12, but the transmission structure of the worm gear 33 and worm 34 therein can also self-lock before and after rotation, ensuring that the slider 2 remains stably at the desired height. The two connecting plates 12a not only provide installation conditions for the screw 31, but also further enhance the structural stability of the two support plates 12, ensuring that the slider 2 and the U-shaped support base 4 can stably support the winding roller 5.

[0025] Furthermore, the worms 34 in the two drive assemblies 3 are coaxial, and the adjacent ends of the two worms 34 are fixedly connected to a transmission shaft 36 that passes through the two support plates 12. The two drive assemblies 3 share the same motor 2 35, and the output end of the motor 2 35 and one end of the transmission shaft 36 are respectively connected to the two ends of the worm 34. By adopting this transmission shaft 36, not only can the synchronization of the sliding of the two sliders 2 be effectively guaranteed, but also one motor 2 35 can be eliminated, reducing the energy consumption and manufacturing cost of the winding device.

[0026] Furthermore, the lower end of the support plate 12 is bent, and the bent portion is horizontally supported on the ground, and the second motor 35 is fixed to the bent portion of the support plate 12. By adopting the support plate 12 with the above structure, not only can the structural stability of the triangular frame 1 be further enhanced, but also sufficient conditions for the installation of the second motor 35 are provided.

[0027] Furthermore, the slider 2 is square, and a horizontal support surface 21 is cut into one of its corners, and the U-shaped support base 4 is fixed on the support surface 21. By adopting the above-mentioned support surface 21, the opening of the U-shaped support base 4 can be made to face vertically upward, thereby making it convenient for workers to use a crane or lifting equipment to quickly place the ends of the winding roller 5 into the U-shaped support base 4 or remove it from the U-shaped support base 4.

[0028] Furthermore, a U-shaped groove 41U is defined within the U-shaped support base 4, with bearings 51 mounted at each end of the winding roller 5, each of which fits within the U-shaped groove 41U. A threaded hole 42 is defined on one side of the U-shaped support base 4, extending through the inner wall of the U-shaped groove 41U. A locking screw 43 is threadedly connected to the threaded hole 42, which locks the outer ring of the bearing 51. The use of the bearing 51 and the U-shaped groove 41U not only significantly reduces friction between the winding roller 5 and the interior of the U-shaped support base 4, but also, in conjunction with the threaded hole 42 and the locking screw 43, fully restricts the rotation of the two ends of the winding roller 5 within the U-shaped support base 4, thereby ensuring the safe winding of the winding roller 5.

[0029] The working principle of this embodiment is as follows:

[0030] When it is necessary to roll up the white card paper, first, the two ends of the winding roller 5 are placed in the two U-shaped support seats 4, and the bearing 51 is stuck in the U-shaped groove 41U inside the U-shaped support seat 4, the sprocket 8 is meshed with the chain 7, and then the locking screw 43 on one side of the U-shaped support seat 4 is tightened to lock the bearing 51 in the U-shaped groove 41U, and the installation preparation work of the winding roller 5 can be completed simply and quickly; then, the motor 2 35 is started to drive the worm 34, the transmission shaft 36 and the other worm 34 to rotate synchronously. Since the worm 34 meshes with the worm wheel 33, the worm wheel 33 is connected to one end of the screw rod 31, so under the meshing transmission of the worm 34 and the worm 34, the two screw rods 31 will rotate respectively in the middle of the two pairs of support plates 12, and because the nut 32 on the slider 2 is threadedly connected to the screw rod 31, When the rod 31 rotates, the two nuts 32 will respectively drive the two sliders 2 to slide upward synchronously along the two pairs of support plates 12; after that, the two U-shaped support seats 4 will drive the winding roller 5 to rise relative to the entire triangular frame 1 under the movement of the two sliders 2, and in this way, the radius of the paper roll wound by the winding roller 5 is not limited by the height; finally, after the winding roller 5 reaches the appropriate height, the motor 1 9 is turned off, and after one end of the white card paper is connected to the winding roller 5, the motor 2 35 is turned on to drive the sprocket 1 6 to rotate and the chain 7 to move. Since the sprocket 2 8 was previously engaged with the chain 7 and was raised as the winding roller 5 moved, it still remained engaged with the chain 7 by rotating while moving. Therefore, when the chain 7 moved, the sprocket 2 8 will also drive the entire winding roller 5 to rotate actively, thereby realizing the rotation of the winding roller 5 to rewind the white card paper.
