Description

Technical Field

[0001] The utility model belongs to the technical field of industrial raw material bundling equipment, and particularly relates to an adjustable unwinding reel suitable for steel strips with a width of 32 mm or more. Background Art

[0002] The reel trolley is a device that supplies strapping equipment with strapping tape. It is generally composed of three major components: a base, a strap accumulator, and a payout reel. The strap accumulator and payout reel are fixedly mounted on the base, and the strapping tape in the payout reel is stored in the payout reel in the form of a reel. Before supplying strapping tape to strapping equipment such as strapping mechanisms, the strapping tape in the payout reel must first be sent to the strap accumulator. The strap accumulator generally uses a storage mechanism consisting of a fixed pulley block and a movable pulley block. By changing the distance between the fixed pulley block and the movable pulley block, the strap required for strapping is first stored in the strap accumulator. When the strapping tape in the strap accumulator is used up, the strapping tape is supplied to the strap accumulator via the payout reel.

[0003] The material and width of the strapping tape vary depending on the object being bundled. When bundling lighter items, plastic strapping with a smaller width (e.g., 10-19mm) is generally used. When bundling heavier materials, such as stacks of metal raw materials, plastic-steel or steel strapping with a wider width (e.g., 32mm or larger) is required to ensure the stability of the bundle and avoid accidents such as strap breakage during packaging, transfer, or transportation.

[0004] In addition to being wound and stored in the tape storage device, the strapping tape is mainly wound on the tape unwinding reel. The tape unwinding reel is generally a storage device for strip materials composed of two parallel circular discs connected by a coaxial shaft. In order to facilitate the release of the stored strapping and prevent it from being strung together, the strapping tape is not directly wound on the shaft, but on an internal support structure that is coaxial with the shaft. However, due to the relatively large weight of strapping tape with a width of 32mm and above, an internal support structure with greater structural strength is required. At the same time, the unwinding process of the strapping tape is generally driven by a motor or released manually. The excessive weight of the unwinding reel itself will undoubtedly increase the energy consumption or labor intensity of the working process. In addition, at present, the internal support structure of the unwinding reel is often an integrated structure connected to the side disc, and the storage capacity can only be adjusted by the amount of strapping tape wound. If the storage capacity exceeds the maximum storage capacity, the entire reel needs to be replaced. Utility Model Content

The circular disk body 61 is provided with three slots 62, evenly spaced along the circumference, for connecting to the side of the circumferential support body 5 where the notch II 54 is provided. Six connection holes IV 64 are also provided circumferentially outside the shaft connection seat 65 to facilitate secure connection to the adjacent side disk 1.

[0051] Figure 8 The figure schematically shows a front view of the structure of a tape reel according to a preferred embodiment of the present invention. Figure 9 for Figure 8 Schematic diagram of the three-dimensional structure. Figure 10 for Figure 8 Schematic diagram of the three-dimensional structure from another perspective. Figure 8-10 It can be seen that in this preferred embodiment, the side plates each adopt a Figure 1 and Figure 2 The side plate 1 shown is also provided with a hand wheel 7. Figure 1 The fixed plate 6 is installed on the outer side of the side plate 1. Figure 2 The hand wheel 7 is installed on the outside of the side plate 1. The shaft 2 passes through the two side plates and passes through the main body from one side of the fixed plate 6, and is connected to the bracket, power mechanism and other components.

[0052] A core support body 3 is mounted on the shaft 1 between the two side discs 1. This core support body 3 is equipped with three wings 32, each connected to a vertical plate 52 of a circumferential support body 5 via two connecting plates 4, forming a hinged structure. To secure the circumferential support body 5, one side of the circumferential support body 5 is provided with a notch I 53, which engages with the spokes 12 of the side disc 1. On the other side of the circumferential support body 5, the notch II 54 of the extended vertical plate 52 is inserted into the bar hole 62, leaving three positioning holes 56 on either side of the notch II 54, allowing for bolt fixation.

[0053] On the side connected to the fixed plate 6, shaft 2 extends from the payout reel. Connecting hole IV 64 on the fixed plate 6 corresponds to connecting hole I14 on the side plate 1, and the connection is secured by bolts. On the side without the fixed plate 6, shaft 2 can be directly connected to the handwheel or indirectly connected using a known coupling method. Rotating the handwheel drives the entire feed reel to release or tighten the strapping strap.

[0054] The side discs of the above tape feed discs are connected by means of inner and outer rings and spokes, which greatly reduces the weight of the tape unwinding disc itself. At the same time, the structure supporting the strapping belt inside the disc body can be three (or a few) and does not have to be wrapped around the outside of the shaft, further reducing the weight of the device. At the same time, the hinge structure formed by the core support body, the connecting plate and the circumferential support body can change the support outer diameter of the support body by telescoping. One side of the circumferential support body is connected to one side of the side disc through a U-shaped notch, and the other side is limited by the bar hole and the position is adjusted up and down. Positioning holes are provided on both sides of the corresponding part of the movable notch in the bar hole. The positioning holes can be bar-shaped holes to adapt to the position change of the adjustment (the hole position can also be fixed by installing nuts of different outer diameters to fix the position).

[0055] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
