Description

Technical Field

[0001] This utility model relates to the field of fabric filament splitting and expansion technology, specifically to a quick roller changing mechanism for a fabric intelligent control expansion device. Background Technology

[0002] In the dyeing and printing process, to maintain the fabric's stretch and prevent uneven processing during dyeing and washing due to shrinkage, widening rollers are often used to stretch the fabric's edges. Different fabrics will produce different stretching effects when passing through the same widening roller, so it is necessary to adjust the wrap angle of the fabric on the widening roller to improve the stretching effect. Currently, most dyeing and printing companies use a separate tension roller next to the widening roller, changing the wrap angle of the widening roller by changing the position of the tension roller. However, this method still cannot meet the stretching requirements of some fabrics. Sometimes, it may be necessary to increase the number of widening rollers to achieve the required stretching effect. On this basis, it may be necessary to add tension rollers, making the equipment structure and installation complex and cumbersome, and the operation of adjusting the wrap angle is also difficult.

[0003] A search revealed an adjustable widening device (publication number: CN211079657U) in the prior art, which describes that "the two widening rollers are arranged parallel to each other and are respectively a first widening roller and a second widening roller; a turntable is provided with a meshing main shaft gear and a transmission gear, and the ends of the first widening roller and the second widening roller are respectively provided with a first gear and a second gear, wherein the first gear meshes with the main shaft gear and the second gear meshes with the transmission gear, and the main shaft gear is driven by a motor; the turntable is rotatably mounted on a housing." This device widens the edge of the fabric using two parallel widening rollers, resulting in a better widening effect and allowing for... The rotation of the turntable changes the wrap angle of the two expansion rollers, eliminating the need for additional tension rollers and offering simple and efficient operation. However, since both ends of the expansion rollers are movably connected to the turntable, the fabric between the two rollers cannot be easily separated. When the expansion rollers wear out after a period of use and need to be replaced, the turntable must be removed first to separate the expansion rollers from the fabric before replacement can be performed. Furthermore, before installing the turntables at both ends of the new expansion rollers, the fabric must be laid between the new rollers for subsequent installation. This makes the replacement process for the expansion rollers cumbersome, prolongs the replacement time, and ultimately reduces the efficiency of fabric production. Utility Model Content

[0019] Reference Figures 1 to 5As shown, this utility model provides a quick roller changing mechanism for a fabric intelligent control expansion device, including: a base 1, a through-hole in the left bend of the base 1, a variable frequency motor 7 fixedly connected inside the through-hole, and a through hole in the right bend of the base 1. A sleeve 15 is movably connected to the through hole via a bearing, and one end of a main screw 16 is screwed into the sleeve 15. The other end of the main screw 16 is fixedly connected to a fastening plate 11, and positioning holes are symmetrically opened on the surface of the fastening plate 11. A rotating ring 14 is fixedly connected to the end of the sleeve 15 away from the fastening plate 11. The surface of the main fixed plate 4 is movably connected to the main expanding roller 3 and the driven expanding roller 2 via bearings. The ends of the main expanding roller 3 and the driven expanding roller 2 away from the main fixed plate 4 are movably connected to the auxiliary fixed plate 9 via bearings. The lower surfaces of the main fixed plate 4 and the auxiliary fixed plate 9 are provided with positioning grooves 17. The upper surface of the base 1 is connected to the positioning block 5 corresponding to the position of the positioning groove 17. The main expanding roller 3 and the driven expanding roller 2 are engaged by the transition wheel 6. The driven wheel 8 fixedly connected to the main expanding roller 3 engages with the driving wheel fixedly connected to the output shaft of the variable frequency motor 7.

[0020] In this embodiment, when the fabric intelligent control widening device needs to change rollers, the PLC intelligent control component shuts down the electrically connected variable frequency motor 7. The rotating ring 14 rotates the sleeve 15, which, through the screwed main screw 16, drives the fastening plate 11 and guide rod 12 to move synchronously. This causes the fastening plate 11 to detach from the surface of the secondary fixing block, and the positioning rod 10 to disengage from the positioning hole. This releases the restriction between the base 1 and the main widening roller 3 and the secondary widening roller 2, allowing workers to quickly remove the main widening roller 3 and the secondary widening roller 2 from the base 1. The fabric between the main widening roller 3 and the secondary widening roller 2 can also detach from the gap between the two sets of secondary fixing plates 9, thus preventing the fabric from interfering with the disassembly of the main widening roller 3 and the secondary widening roller 2. A new main widening roller 3 and a new secondary widening roller 2 are then installed on the base. When installing the fabric on the base 1, first insert the fabric into the gap between the corresponding secondary fixing plates 9 so that the fabric is positioned between the new main expansion roller 3 and the new secondary expansion roller 2. Then, align the positioning grooves 17 of the corresponding main fixing plate 4 and secondary fixing plate 9 with the positioning block 5. Subsequently, the positioning block 5 can be smoothly embedded into the positioning grooves 17 opened in the main fixing plate 4 and secondary fixing plate 9, thereby completing the initial installation of the expansion roller. In the reverse rotation ring 14, the rotation ring 14 drives the sleeve 15 to push the main lead screw 16 and the fastening plate 11 to reset. At this time, the worker fine-tunes the angle of the secondary fixing plate 9 so that the positioning rod 10 on the surface of the secondary fixing plate 9 can be smoothly embedded into the positioning hole opened in the surface of the fastening plate 11, thereby completing the installation of the new expansion roller. This effectively improves the efficiency of roller changing in the expansion device, shortens the time required for roller changing, and helps to improve the production efficiency of the fabric.

[0021] In a preferred embodiment, the base 1 has a U-shaped structure and is composed of a substrate, a left bend and a right bend. The width of the left bend and the right bend are both greater than the width of the substrate. At the same time, the left bend and the right bend are both rectangular, while the substrate is elongated.

[0022] In this embodiment, as Figure 1 and Figure 3 The overall structure of the base 1 facilitates the installation of the frequency conversion motor 7, sleeve 15 and main lead screw 16, ensures that the corresponding components can be installed inside the base 1, and ensures that the main expansion roller 3 and the secondary expansion roller 2 can rotate smoothly.

[0023] In a preferred embodiment, the main fixing plate 4 has a rectangular structure, while the two sets of auxiliary fixing plates 9 have square structures. The positioning grooves 17 opened on the main fixing plate 4 and the auxiliary fixing plates 9 have square structures, and the dimensions of the positioning grooves 17 and the positioning blocks 5 are compatible. At the same time, the main fixing plate 4, the main expanding roller 3, the secondary expanding roller 2 and the auxiliary fixing plates 9 are combined to form a U-shaped structure.

[0024] In this embodiment, as Figure 1 and Figure 2 The arrangement of the main fixing plate 4, the main expanding roller 3, the secondary expanding roller 2 and the auxiliary fixing plate 9 allows the main expanding roller 3 and the secondary expanding roller to be easily and uniformly installed and removed, and also facilitates the placement and separation of the main expanding roller 3 and the secondary expanding roller 2 from the fabric, thereby improving the efficiency of roller changing.

[0025] In a preferred embodiment, two sets of positioning rods 10 are symmetrically connected to the side of the secondary fixing plate 9 near the fastening plate 11. Both sets of positioning rods 10 are cylindrical in shape, and the size of the positioning rods 10 and the positioning holes opened on the surface of the fastening plate 11 are compatible.

[0026] In this embodiment, as Figure 2 , Figure 3 and Figure 4 The positioning rod 10 and the positioning hole are matched in size, which can help enhance the clamping and fixing effect of the fastening plate 11 on the secondary fixing plate 9, and avoid the secondary fixing plate 9 from shaking or being misaligned during the rotation of the main expanding roller 3 and the secondary expanding roller 2.

[0027] In a preferred embodiment, the fastening plate 11 has a rectangular structure, and the two sets of guide rods 12 fixedly connected to the surface of the fastening plate 11 are both cylindrical structures. The dimensions of the guide rods 12 and the guide holes 13 are matched, and scale lines are opened on the surface of the guide rods 12. The fastening plate 11 and the guide rods 12 are combined to form a Π-shaped structure.

[0028] In this embodiment, as Figure 3 , Figure 4 and Figure 5The guide rod 12 and the guide hole 13 are matched in size, which can help enhance the stability of the fastening plate 11 when it moves, and also prevent the main screw 16 and the fastening plate 11 from rotating synchronously with the sleeve 15. At the same time, the scale lines on the surface of the guide rod 12 make it easy for workers to confirm the moving distance of the fastening plate 11 in real time.

[0029] In a preferred embodiment, the sleeve 15 has a cylindrical structure, the axial length of the sleeve 15 is greater than the thickness of the right bend of the base 1, and the inner cavity of the sleeve 15 is screwed to the main screw 16 through a threaded structure. Meanwhile, the rotating ring 14 fixedly connected to the end face of the sleeve 15 has a circular structure, and the surface of the rotating ring 14 is movably connected to the handle through a bearing. The surface of the handle is evenly provided with anti-slip stripes.

[0030] In this embodiment, as Figure 3 , Figure 4 and Figure 5 The handle movably connected to the surface of the rotating ring 14 makes it easy for the worker to rotate the rotating ring 14. At the same time, the sleeve 15 and the rotating ring 14 allow the worker to conveniently adjust the position of the fastening plate 11 through the main screw 16, thereby realizing convenient loading and unloading between the main expansion roller 3 and the secondary expansion roller 2 and the base 1.

[0031] In a preferred embodiment, the through-hole in the left bend of the base 1 has a square structure, and the through-hole extends through both sides of the left bend. The output shaft of the variable frequency motor 7 is fixedly connected to the drive wheel. The size of the drive wheel is smaller than that of the driven wheel 8, while the size of the driven wheel 8 is larger than that of the transition wheel 6.

[0032] In this embodiment, as Figure 1 , Figure 3 and Figure 5 The size of the driving wheel is smaller than that of the driven wheel 8, so the variable frequency motor 7 and the main expansion roller 3 can form an equivalent speed reducer. At the same time, the PLC intelligent control component fixedly connected to the surface of the left bending part can be a common brand model on the market.
