Abstract
Description
Technical Field
[0001] This utility model relates to the field of carpet edge-locking technology, specifically to an auxiliary belt edge-locking device for carpets. Background Technology
[0002] Carpet overlocking refers to the special treatment of the carpet edges to prevent curling, shifting, or wear during use. This treatment typically involves using a special material or method to ensure the carpet's flatness and durability. There are several methods for carpet overlocking, including using edge trimming strips, flame-sealing the edges, and machine sewing. Edge trimming strips are a common solution that not only prevents the carpet edges from curling but also increases aesthetics and durability. Flame-sealing the edges is a traditional method that treats the carpet edges with a flame; while it effectively prevents shedding, it may produce black edges and unpleasant odors. Machine sewing is a more refined and durable method, using a sewing machine to tightly sew the carpet edges together to prevent edge wear and fraying.
[0003] A carpet overlock machine is a machine specifically designed for sewing the edges of carpets. It uses needles and thread to fix the carpet edges, ensuring that the carpet is both beautiful and sturdy. The structure of a carpet overlock machine mainly consists of the following parts: frame, feeding mechanism, main shaft drive system, sewing machine, thread cutter, fabric pulling mechanism, cutting mechanism, sewing machine, and electrical control system. Carpet overlock materials mainly include polyester thread, cotton thread, and metal binding. Since most carpets use thread materials for overlocking, conventional overlock machines do not have a belt conveyor structure. When using edge trim materials for overlocking, an overlock machine suitable for edge trim needs to be purchased separately, increasing costs. Utility Model Content
[0004] The purpose of this invention is to provide an auxiliary belt overlocking device for carpets, so as to solve the problem that conventional overlocking machines do not have a belt conveyor structure.
[0005] To achieve the above objectives, the basic solution provided by this utility model is as follows: an auxiliary belt edge-locking device for carpets, comprising a base, a reversing shaft and an adjusting component. The adjusting component is an S-shaped multi-layer frame, which is threadedly connected to the edge-locking machine. The adjusting component is provided with an adjusting component for adjusting the belt tension. The base and the reversing shaft are both fixedly connected to the edge-locking machine. A main shaft is fixedly connected to the base, and a rotating tube is rotatably sleeved on the main shaft.
[0006] The principle and beneficial effects of this utility model are as follows: In use, the belt is wound around the main shaft, and the free end of the belt wound passes through the reversing shaft and the adjusting component in sequence, and finally enters the sewing machine of the overlock machine. According to the actual structure of the overlock machine, the belt path is changed by the reversing shaft, which increases the practicality of the device. According to the material of the overlock, the tension of the belt can be changed by the adjusting component according to the elasticity of the material, which further increases the practicality of the device. Since the adjusting component is an S-shaped multi-layer frame, when the belt enters the sewing machine, the curling or misalignment of the belt can be reduced. The device has a simple structure and is easy to operate.
[0007] Option 2, which is a preferred option of the basic option, has a pressure plate threaded onto the main shaft, and a limiting component for limiting the belt is fixed to the pressure plate; the belt roll is sleeved on the main shaft, and then the pressure plate is pressed to a position suitable for the belt width, increasing the weight of the belt roll, which can reduce the loosening of the belt roll when the overlock machine is paused or the carpet is changed, thus increasing the practicality of the device.
[0008] Option 3, which is a preferred option of Option 2, includes four clamping components, each of which is fixed to the inside of the pressure plate. In use, the clamping components press against the outer ring of the belt roll. As the belt roll is used, the diameter of the belt roll decreases, which can prevent the belt roll from loosening in the later stages of use and increase the practicality of the device.
[0009] Option 4 is a preferred option of the basic option. The adjustment component includes a limiting plate, which is threadedly connected to the overlock machine. The limiting plate has several limiting holes, and the limiting plate and the adjusting component are bolted together. Since the belt material is different, the belt tension is also different. When using the device, the position of the adjusting component on the limiting plate is set according to the actual situation of the belt to increase the practicality of the device.
[0010] Option 5, which is a preferred option of the basic option, has a movable tube rotatably connected to the reversing shaft; in use, it converts sliding friction into rolling friction, reduces friction between the belt and the reversing shaft, and also increases the service life of the device.
[0011] Option 6, which is a preferred option of the basic option, has an adjusting tube threaded onto the adjusting component; when the belt width increases, the adjusting tube can be threaded onto the adjusting component to increase the width of the adjusting component, thereby increasing the practicality of the device.

[0017] Example
[0018] like Figures 1 to 3 As shown: A carpet auxiliary belt edge-locking device includes a base 1, a reversing shaft 6, and an adjusting component 7. The adjusting component 7 is an S-shaped multi-layer frame. The adjusting component 7 is threadedly connected to the edge-locking machine 11. An adjusting tube 10 is threadedly connected to the adjusting component 7. The adjusting component 7 is provided with an adjusting assembly for adjusting the belt tension. The adjusting assembly includes a limiting plate 8, which is threadedly connected to the edge-locking machine 11. The limiting plate 8 has several limiting holes 12. The limiting plate 8 and the adjusting component 7 are bolted together. The base 1 and the reversing shaft 6 are both fixedly connected to the edge-locking machine 11. A main shaft 4 is fixedly connected to the base 1. A rotating tube 5 is rotatably sleeved on the main shaft 4. A pressure plate 2 is threadedly connected to the main shaft 4. A limiting assembly for limiting the belt is fixedly connected to the pressure plate 2. The limiting assembly includes four clamping parts 3, each of which is fixedly connected to the inner side of the pressure plate 2. A movable tube 9 is rotatably connected to the reversing shaft 6.
[0019] The implementation method of this embodiment is as follows: During installation, firstly, the limiting plate 8 is threaded onto the overlock machine 11 to facilitate the belt entering the sewing machine 11. Then, the base 1 and the reversing shaft 6 are welded onto the overlock machine 11. Next, the pressure plate 2 is rotated to separate the pressure plate 2 from the main shaft 4, and the belt roll is sleeved on the rotating tube 5. Then, the pressure plate 2 is rotated again to press against the upper side of the belt roll. At the same time, the two clamping parts 3 are pried up so that the four clamping parts 3 press against the outer ring of the belt roll respectively. Finally, the free end of the belt roll is passed around the movable tube 9 and the adjusting part 7 in sequence, and finally enters the sewing machine 11; overlocking. When machine 11 starts sewing, as the free end of the belt is sewn onto the carpet, the movable tube 9 and the rotating tube 5 rotate with the belt. At the same time, the clamping parts 3 gradually shrink as the belt roll is used, so that the belt roll cannot loosen. When changing the belt roll, rotate the pressure plate 2 to separate the pressure plate 2 from the main shaft 4, put the new belt roll on the rotating tube 5, and then rotate the pressure plate 2 so that the pressure plate 2 presses against the upper side of the belt roll. At the same time, pry up the two clamping parts 3 so that the four clamping parts 3 press against the outer ring of the belt roll respectively. Finally, the free end of the belt roll passes through the movable tube 9 and the adjusting part 7 in sequence, and finally enters the sewing machine of the overlock machine 11.
