Description

Technical Field

[0001] This utility model relates to the field of frame technology, and more specifically to a structurally stable fabric rolling frame. Background Technology

[0002] Fabric winding machines are core equipment in the textile industry used for winding and storing fabrics. The fabric winding frame is a major component of the machine, and its structural stability directly affects production efficiency and safe operation. Traditional fabric winding frames are typically constructed by welding or bolting together components such as a vertical box, a lower tube, reinforcing square tubes, and side square tubes. However, under long-term high-speed rotation and load conditions, the following defects exist: frequent loosening of connections: for example, the interface between the lower tube and the vertical box is only fixed by simple welding or bolts, lacking an effective limiting mechanism. This causes fretting wear during dynamic rotation of the frame, which over time leads to structural instability, increased noise, and even the risk of breakage. Utility Model Content

[0003] The purpose of this utility model is to provide a structurally stable fabric rolling frame in order to solve the above-mentioned technical problems.

[0004] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0005] A structurally stable fabric rolling frame includes vertical boxes, a lower tube is provided between the bottoms of the two vertical boxes, and a reinforcing square tube is connected between the two lower tubes;

[0006] Two lateral tubes are connected to the side walls of the two vertical boxes. The lateral tubes are arranged parallel to each other on both sides of the width direction of the vertical boxes.

[0007] Both ends of the lower tube are provided with connecting seats;

[0008] The connecting seat includes an L-shaped plate with a vertical plate on its bottom. The L-shaped plate is flush against the bottom corner of the vertical box and fixed to the side wall of the vertical box using screws and bolts. The side wall of the L-shaped plate is welded to the lower tube. The bottom of the vertical box has a insertion hole through which the vertical plate is inserted. The L-shaped plate is designed to ensure a tighter fit between the lower tube and the vertical box, making the connection more secure and preventing loosening at the connection point during frame rotation. The insertion hole at the bottom of the vertical box allows the vertical plate to be inserted into the vertical hole, serving as a limiting mechanism. The L-shaped plate and the vertical plate are integrally formed.

[0009] The reinforced square tube is provided with mounting bases at both ends;

[0010] The mounting base includes a right-angled folding plate with a limiting part at its bottom. The side wall of the folding plate is welded to the reinforcing square tube. The right-angled folding plate is tightly attached to the bottom of the lower tube and fixed to the side wall of the lower tube by screws and bolts. The bottom of the right-angled folding plate provides support contact to the bottom of the lower tube, while the side and limiting parts of the right-angled folding plate limit and fix both sides of the lower tube. The right-angled folding plate and limiting parts ensure a firm connection between the reinforcing square tube and the lower tube.

[0011] The side tube is provided with limiting steps at both ends. The side tube is closely fitted to the vertical box through the limiting steps. Both ends of the side tube are welded with connecting plates, and the connecting plates are connected and fixed to the side wall of the vertical box by bolts and screws.

[0012] The vertical box is equipped with a cover plate on its outer side. The edge of the cover plate is fixed to the vertical box with screws and bolts. Multiple rubber support sleeves are installed on the inner wall of the vertical box. When the cover plate is fixed to the vertical box, the rubber support sleeves are pressed tightly against the cover plate. The rubber support sleeves provide support and cushioning for the cover plate, preventing it from deforming upon impact. The rubber support sleeves are either bonded to the vertical box or fixed with screws.

[0013] The inner side of the cover plate is provided with two parallel rubber fixing posts, and the side wall of the side tube is provided with fixing grooves that mate with the rubber fixing posts. The vertical box contains many components, and when the fabric rolling machine malfunctions, the cover plate needs to be opened for repair. Currently, there is no designated place for the cover plate; usually, it is simply leaned against the side tube or a corner. This is unsafe, as the cover plate is easily bumped and damaged or can cause injury. By providing fixing grooves and rubber fixing posts, the cover plate can be temporarily fixed to the side tube, making the fixation quick and convenient.

[0014] The two rubber fixing posts are inserted into two rubber support sleeves located above the vertical box. The insertion of the rubber fixing posts and rubber support sleeves serves as a positioning mechanism, facilitating the connection and fixation of the cover plate and the vertical box by the operators. The outer diameter of the rubber fixing posts is the same as the inner diameter of the rubber support sleeves, ensuring that the cover plate is fixed to the rubber support sleeves when the rubber fixing posts are inserted.

[0015] The outer wall of the rubber support sleeve is provided with a large winding groove and a small winding groove, the width and depth of which are larger than those of the small winding groove. Many wires are arranged inside the vertical box; without proper routing, the wires would appear messy and difficult to inspect later. By setting up the large and small winding grooves, the wires can be neatly wound and routed, preventing them from tangling.

[0016] This utility model employs a multi-layered reinforcement design to ensure the frame maintains rigidity under high-load rotation conditions. Specifically, the integrated structure of the L-shaped plate and the vertical plate (inserted through the insertion holes at the bottom corners of the vertical box), combined with double fixing with screws and bolts, forms a mechanical interlock, effectively absorbing shear forces and vibrations during rotation; at the same time, the right-angle folding plate and the limiting part provide three-dimensional limiting (support contact and lateral constraint) at the interface between the reinforced square tube and the lower tube, preventing loosening caused by fretting wear.

[0017] The beneficial effects of this utility model are as follows:

[0018] This invention ensures that the frame remains rigid under high-load rotation conditions by setting a connecting seat, a mounting seat, and a limiting step, thereby extending the service life of the equipment, reducing noise, and minimizing downtime losses and safety accidents.

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0027] Example 1

[0028] like Figures 1 to 5 As shown, this embodiment provides a structurally stable fabric rolling frame, including a vertical box 1, a lower tube 2 between the bottoms of the two vertical boxes 1, and a reinforcing square tube 3 connecting the two lower tubes 2;

[0029] Two side tubes 4 are connected to the side walls of the two vertical boxes 1. The two side tubes 4 are arranged in parallel on both sides of the width direction of the vertical box 1.

[0030] Both ends of the lower tube 2 are provided with connecting seats 5;

[0031] The connecting seat 5 includes an L-shaped plate 6, with a vertical plate 7 on its bottom. The L-shaped plate 6 is tightly fitted to the bottom corner of the vertical box 1 and fixed to the side wall of the vertical box 1 by screws and bolts. The side wall of the L-shaped plate 6 is welded to the lower tube 2. The bottom of the vertical box 1 has an insertion hole 8, through which the vertical plate 7 is inserted into the vertical box 1. The L-shaped plate 6 is designed to ensure a tighter fit between the lower tube 2 and the vertical box 1, making the connection more secure and preventing loosening at the connection point when the frame rotates. The insertion hole 8 at the bottom of the vertical box 1 allows the vertical plate 7 to be inserted into the vertical hole, serving as a limiting device. The L-shaped plate 6 and the vertical plate 7 are integrally formed.

[0032] The reinforced square tube 3 is provided with mounting bases 9 at both ends;

[0033] Mounting base 9 includes a right-angled folding plate 10, with a limiting part 11 at its bottom. The side wall of the right-angled folding plate 10 is welded to the reinforcing square tube 3. The right-angled folding plate 10 is tightly attached to the bottom of the lower tube 2 and is fixed to the side wall of the lower tube 2 by screws and bolts. The bottom of the right-angled folding plate 10 provides support contact to the bottom of the lower tube 2, and the side of the right-angled folding plate 10 and the limiting part 11 limit and fix both sides of the lower tube 2. By setting the right-angled folding plate 10 and the limiting part 11, the connection between the reinforcing square tube 3 and the lower tube 2 is made firm.

[0034] The side tube 4 is provided with limiting steps 12 at both ends. The side tube 4 is closely fitted and limited to the vertical box 1 by the limiting steps 12. Both ends of the side tube 4 are welded with connecting plates 13. The connecting plates 13 are connected and fixed to the side wall of the vertical box 1 by bolts and screws.

[0035] The vertical box 1 has a cover plate 14 on its outer side. The edge of the cover plate 14 is fixed to the vertical box 1 by screws and bolts. Multiple rubber support sleeves 15 are provided on the inner wall of the vertical box 1. When the cover plate 14 is fixed to the vertical box 1, the rubber support sleeves 15 are pressed tightly against the cover plate 14. The rubber support sleeves 15 provide support and cushioning for the cover plate 14, preventing it from deforming due to impact. The rubber support sleeves 15 are bonded to the vertical box 1 or fixed with screws.

[0036] The inner side of the cover plate 14 is provided with two parallel rubber fixing posts 16, and the side wall of the side tube 4 is provided with fixing grooves 17 that cooperate with the rubber fixing posts 16 for insertion. There are many components assembled inside the vertical box 1. When the fabric rolling machine malfunctions, the cover plate 14 needs to be opened for maintenance. Currently, there is no place designed for the cover plate 14. Usually, the cover plate 14 is directly leaned against the side tube 4 or a corner. This practice is relatively unsafe, as the cover plate 14 can easily be bumped and damaged or scratched. By setting the fixing grooves 17 and the rubber fixing posts 16, the cover plate 14 can be temporarily fixed to the side tube 4, which is quick and convenient.

[0037] The two rubber fixing posts 16 are inserted into the two rubber support sleeves 15 located above the vertical box 1. The rubber fixing posts 16 and the rubber support sleeves 15 are inserted to provide a positioning function, making it convenient for workers to connect and fix the cover plate 14 and the vertical box 1. The outer diameter of the rubber fixing post 16 and the inner diameter of the rubber support sleeve 15 are the same, so that when the rubber fixing post 16 is inserted into the rubber support sleeve 15, the cover plate 14 is fixed on the rubber support sleeve 15.

[0038] The outer wall of the rubber support sleeve 15 is provided with a large winding groove 18 and a small winding groove 19. The width and depth of the large winding groove 18 are both larger than those of the small winding groove 19. Many wires will be arranged inside the vertical box 1. If the wires are not properly routed, they will appear messy and inconvenient for later inspection. By setting up the large winding groove 18 and the small winding groove 19, the wires can be neatly wound and routed, preventing them from tangling.

[0039] This utility model employs a multi-layered reinforcement design to ensure the frame maintains rigidity under high-load rotation conditions. Specifically, the integrated structure of the L-shaped plate 6 and the vertical plate 7 (inserted through the insertion hole 8 at the bottom corner of the vertical box 1), combined with double fixing by screws and bolts, forms a mechanical interlock, effectively absorbing shear force and vibration during rotation; at the same time, the right-angle folding plate 10 and the limiting part 11 provide three-dimensional limiting (support contact and lateral constraint) at the interface between the reinforced square tube 3 and the lower tube 2, preventing loosening caused by fretting wear.
