Description

Technical Field

[0001] This utility model relates to the field of textile machinery and equipment technology, and in particular to a fabric feeding device. Background Technology

[0002] The traditional method of loading fabric onto a fabric roll using a fabric spreading machine is to manually lift the roll until it is parallel to the fabric hopper of the machine, then lift it onto the back roller and finally tumble it back onto the hopper. This method is very inconvenient. On the one hand, large-diameter and heavy fabric rolls require multiple people working together to complete the loading process, resulting in high labor intensity, long loading time, and low work efficiency. On the other hand, during the unwinding process, the fabric tension is uneven before and after the unwinding due to the reduced weight of the roll, which affects the quality of subsequent production. Utility Model Content

[0003] In view of the above-mentioned prior art, the present invention provides a fabric feeding device that uses a winch to lift the fabric roll, reducing the physical exertion of workers. The fabric roll is clamped and fixed from both ends by a telescopic shaft and a rotating shaft, and rotates synchronously. A tension adjustment device is installed on the rotating shaft so that the tension of the fabric remains constant throughout the unwinding process, ensuring stable product quality.

[0004] To achieve the above objectives, the technical solution of this utility model embodiment is implemented as follows:

[0005] A fabric feeding device includes two support platforms, with support rods fixedly connected to the support platforms. A crossbar is fixedly connected to the top of the support rod, and a lifting device is installed on the crossbar for lifting the fabric roll. A telescopic clamping device is installed on the support platforms for clamping and fixing the fabric roll with a roll roller. A tension adjusting device is installed on the telescopic clamping device for adjusting the fabric tension of the fabric roll.

[0006] Furthermore, the hoisting device includes a winch, which is installed on the lower surface of the crossbar. The winch's winding and unwinding ends are connected to a main steel cable, which is used to suspend a balance beam. Both ends of the lower surface of the balance beam are connected to auxiliary steel cables. The end of the auxiliary steel cable away from the balance beam is connected to a hook assembly, which is used to fix the fabric roll's winding roller.

[0007] Furthermore, the hook assembly includes a connector, which is fixedly connected to the auxiliary steel cable. A first hook and a second hook are rotatably connected to the lower part of the connector, and the first hook and the second hook are in opposite directions.

[0008] Furthermore, the upper surface of the balance beam is provided with at least two limiting rods, which pass through the crossbar and are slidably connected to the crossbar.

[0009] Furthermore, the telescopic clamping device includes a movable clamping assembly and a stationary clamping assembly. The movable clamping assembly is mounted on one support platform, and the stationary clamping assembly is mounted on another support platform. The movable clamping assembly includes a closed sleeve, and a second movable block is slidably connected inside the closed sleeve. A telescopic shaft is rotatably connected to one side surface of the second movable block. One end of the telescopic shaft passes through one side wall of the closed sleeve and is rotatably connected to the closed sleeve. A first screw is provided inside the closed sleeve. The first screw passes through the second movable block and is threadedly connected to the second movable block. One end of the first screw passes through the other side wall of the closed sleeve and is rotatably connected to the closed sleeve. The stationary clamping assembly includes a support base, and a rotating shaft is mounted on the support base. The axes of the telescopic shaft and the rotating shaft are on the same line, and a tapered head is provided on the opposite end faces of the telescopic shaft and the rotating shaft.

[0010] Furthermore, the tension adjustment device includes a rotating disk, which is installed on the outside of the rotating shaft. The axes of the rotating disk and the rotating shaft coincide. An arc-shaped friction plate is provided on the outer surface of the rotating disk. One end of the friction plate is fixedly connected to the upper surface of the support platform, and the other end of the friction plate is fixedly connected to a first movable block. A second screw is rotatably connected to the upper surface of the support platform. The second screw passes through the first movable block and is threadedly connected to the first movable block.

[0011] Furthermore, the contact surfaces between the first hook and the second hook and the fabric roll roller are rough surfaces.

[0012] Furthermore, a rotating handle is fixedly connected to one end of the first screw located outside the closed sleeve.

[0013] Furthermore, the conical surface of the cone-shaped head is covered with an anti-slip material.

[0014] The beneficial effects of this utility model are as follows: the fabric roll is directly hoisted by a winch, avoiding manual lifting and reducing the workload of personnel. The two ends of the fabric roll are fixed by inserting the telescopic shaft and the rotating shaft respectively. The fabric roll rotates together with the telescopic shaft and the rotating shaft. A tension adjustment device is added to the rotating shaft to ensure that the tension of the fabric remains constant during the unwinding process and will not change due to the weight reduction after unwinding.

[0015] A balance beam is added to the main steel cable to prevent pitching sway during fabric roll hoisting, making the entire hoisting process safer. A limit bar is added to the balance beam to further prevent pitching sway and horizontal swaying of the fabric roll, resulting in better safety during fabric roll hoisting.

[0016] When the two conical heads lock the fabric roll together, an anti-slip material is covered on the conical surface of the conical head to increase the friction between the fabric roll and the conical head. This prevents the fabric roll from sliding relative to the conical head during unwinding, thus preventing unstable fabric tension. Attached Figure Description

Detailed Implementation

[0021] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this utility model belongs. The terminology used in this specification of this utility model is for the purpose of describing particular embodiments only and is not intended to limit the utility model. In the following description, the expression "some embodiments" refers to a subset of all possible embodiments; however, it should be understood that "some embodiments" can be the same subset or different subsets of all possible embodiments and can be combined with each other without conflict.

[0022] Combined with reference to the appendix Figures 1 to 3This utility model provides a fabric loading device, including two support platforms 1. Support rods 2 are fixedly connected to the support platforms 1, and a crossbar 3 is fixedly connected to the top of each support rod 2. A lifting device 4 is installed on the crossbar 3 for lifting the fabric roll. A telescopic clamping device 5 is installed on the support platforms 1 for clamping and fixing the fabric roll's winding roller. A tension adjusting device 6 is installed on the telescopic clamping device 5 for adjusting the fabric tension of the roll. The support platforms 1 are firmly connected to the ground to ensure the stability of the device during fabric roll lifting and unwinding operations. The lifting device 4 reduces the labor intensity of personnel when lifting the fabric roll. After lifting the fabric roll, the telescopic clamping device 5 locks and fixes the fabric roll's winding roller to prevent the winding roller from shaking during unwinding, which could cause unstable fabric tension. The tension adjusting device 6 on the telescopic clamping device 5 ensures that the fabric tension remains consistent throughout the unwinding process, guaranteeing stable quality in subsequent production.

[0023] Preferably, the lifting device 4 includes a winch 7, which is installed on the lower surface of the crossbar. A main steel cable 8 is wound around the winding end of the winch 7. A balance beam 9 is suspended from the main steel cable 8. Secondary steel cables 10 are connected to both ends of the lower surface of the balance beam 9. A hook assembly is connected to the end of the secondary steel cable 10 furthest from the balance beam 9. The hook assembly is used to fix the fabric roll's winding roller. Using the two hook assemblies to fix both ends of the winding roller, the winch 7 is started to lift the fabric roll. The end of the main steel cable 8 furthest from the winch 7 is connected to the balance beam 9, lowering the center of gravity of the fabric roll and preventing it from swaying during lifting. The secondary steel cable 10 connects the balance beam 9 and the hook assembly, allowing the lifted fabric roll to move to a certain extent, facilitating the alignment of the telescopic clamping device 5 with the fabric roll's winding roller.

[0024] Preferably, the hook assembly includes a connector 11, which is fixedly connected to the auxiliary steel cable 10. A first hook 12 and a second hook 13 are rotatably connected to the lower part of the connector 11. The first hook 12 and the second hook 13 are in opposite directions. The first hook 12 and the second hook 13 are at the same height. The first hook 12 and the second hook 13 open to both sides of the fabric roll roller and hook the fabric roll roller respectively, so that the fabric roll roller will not accidentally fall off during the fabric roll lifting process. After the fabric roll roller is locked and fixed by the telescopic clamping device 5, the first hook 12 and the second hook 13 can be easily disengaged from both sides of the fabric roll roller.

[0025] Preferably, the upper surface of the balance beam 9 is provided with at least two limiting rods 14, which pass through the crossbar 3 and are slidably connected to the crossbar 3. When the main steel cable 8 lifts the balance beam 9 upward, due to the limiting effect of the limiting rods 14, the balance beam 9 can only move up and down and will not sway horizontally, which improves the safety when lifting the fabric roll and also improves the efficiency of aligning the fabric roll roller with the telescopic clamping device 5. The auxiliary steel cable 10 is relatively short, which allows the fabric roll to be finely adjusted in the horizontal direction, facilitating manual alignment.

[0026] Preferably, the telescopic clamping device 5 includes a movable clamping assembly and a stationary clamping assembly. The movable clamping assembly is mounted on one support platform 1, and the stationary clamping assembly is mounted on another support platform 1. The movable clamping assembly includes a closed sleeve 15, in which a second movable block 26 is slidably connected. A telescopic shaft 18 is rotatably connected to one side surface of the second movable block 26. One end of the telescopic shaft 18 passes through one side wall of the closed sleeve 15 and is rotatably connected to the closed sleeve 15. A first screw 16 is provided inside the closed sleeve 15. The first screw 16 passes through the second movable block 26 and is threadedly connected to the second movable block 26. One end of the first screw 16 passes through the other side wall of the closed sleeve 15 and is rotatably connected to the closed sleeve 15. The stationary clamping assembly includes a support base 20, on which a rotating shaft 21 is mounted. The axes of the telescopic shaft 18 and the rotating shaft 21 are on the same line. Tapered heads 19 are provided on the opposite end faces of the telescopic shaft 18 and the rotating shaft 21. The rotating shaft 21 included in the stationary clamping assembly can only rotate and cannot move axially. The second movable block 26 in the movable clamping assembly moves towards the rotating shaft 21 within the closed sleeve 15 by rotating the first screw 16. The second movable block 26 pushes the telescopic shaft 18 towards the rotating shaft 21, reducing the distance between the rotating shaft 21 and the telescopic shaft 18. The rotating shaft 21 and the telescopic shaft 18 respectively clamp and fix the two ends of the fabric roll. The telescopic shaft 18 is rotatably connected to the second movable block 26 and can rotate on its own. Therefore, the rotating shaft 21 and the telescopic shaft 18 rotate together with the fabric roll. The opposite shaft end faces of the telescopic shaft 18 and the rotating shaft 21 are provided with conical heads 19. The fabric roll is a hollow tube. The conical head 19 is inserted into part of the interior of the fabric roll, which can effectively prevent the fabric roll from disengaging from the telescopic clamping device 5 during rotation. The conical head 19 can adapt to fabric rolls within a certain tube diameter range and has a wide range of applications.

[0027] Preferably, the tension adjusting device 6 includes a rotating disk 23, which is installed on the outside of the rotating shaft 21. The axes of the rotating disk 23 and the rotating shaft 21 coincide. An arc-shaped friction plate 22 is provided on the outer surface of the rotating disk 23. One end of the friction plate 22 is fixedly connected to the upper surface of the support platform 1, and the other end of the friction plate 22 is fixedly connected to a first movable block 24. A second screw 25 is rotatably connected to the upper surface of the support platform 1. The second screw 25 passes through the first movable block 24 and is threadedly connected to the first movable block 24. The rotating shaft 21 rotates together with the fabric rolling roller, and the rotating disk 23 rotates with the rotating shaft 21. The outer surface of the rotating disk 23 is provided with an arc-shaped friction plate 22. One end of the friction plate 22 is fixedly connected to the upper surface of the support platform 1. When the second screw 25 is rotated, the first movable block 24 moves downward along the axial direction of the second screw 25. One end of the friction plate 22 is fixedly connected to the upper surface of the support platform 1, and the other end of the friction plate 22 moves downward with the first movable block 24. The pressure of the friction plate 22 on the outer surface of the rotating disk 23 increases, and the resistance to the rotation of the rotating disk 23 increases. The rotating disk 23 rotates synchronously with the rotating shaft 21 and the fabric rolling roller. By adjusting the resistance to the rotating disk 23, the resistance to the rotation of the fabric rolling roller is adjusted, so that the tension of the fabric during the unwinding process is not affected by the weight reduction during the unwinding process. The tension of the fabric remains stable and consistent throughout the unwinding process.

[0028] Preferably, the contact surfaces of the first hook 12 and the second hook 13 with the fabric roll's winding roller are rough surfaces. After the first hook 12 and the second hook 13 lift and fix the fabric roll to the winding roller, the first hook 12 and the second hook 13 will not slide along the axial direction of the winding roller, further ensuring that the fabric roll will not slip during the lifting process and improving safety.

[0029] Preferably, a rotating handle 17 is fixedly connected to one end of the first screw 16 located outside the closed sleeve 15. By manually turning the handle 17, the first screw 16 is rotated, the second movable block 26 is moved, and the telescopic shaft 18 is moved axially, which is more labor-saving.

[0030] Preferably, the conical surface of the conical head 19 is covered with an anti-slip material. When the conical head 19 is inserted into the fabric roll roller, the anti-slip material between the ends of the conical head 19 and the fabric roll roller increases the friction, thereby making the conical head 19 and the fabric roll roller rotate more synchronously, reducing relative slippage, and making the tension adjustment of the fabric more stable. The anti-slip material can be nitrile rubber or polyurethane, which has high strength and can withstand a large axial clamping force without damage when the two conical heads 19 approach each other and squeeze the fabric roll roller. It has good friction performance. When the fabric roll is unwound, the fabric roll roller rotates, and the fabric roll roller and the anti-slip material will not slip relative to each other, ensuring that the conical head 19 and the rotating shaft 21 always rotate synchronously with the fabric roll roller.

[0031] Working principle: The first hook 12 and the second hook 13 hook the fabric roll from both sides. The two hook assemblies hook the two ends of the fabric roll. Start the winch 7 to lift the fabric roll to a certain height. Crank the handle 17 by hand to rotate the first screw 16. The second movable block 26 moves and the telescopic shaft 18 moves closer to the rotating shaft. The conical head 19 on the telescopic shaft 18 and the rotating shaft 21 is inserted into the fabric roll and locked on the left and right. The telescopic shaft 18 and the rotating shaft 21 rotate together with the unwinding fabric roll. Rotate the second screw 25 and the first movable block 24 moves, changing the pressure of the friction plate 22 on the outer surface of the rotating disk 23. The resistance to the rotation of the friction plate 22 changes, that is, the resistance to the unwinding fabric roll changes, thereby adjusting the fabric tension when the fabric roll is unwound.

[0032] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. The protection scope of this utility model should be determined by the protection scope of the stated claims.
