Description

Technical Field

[0001] This utility model belongs to the field of fabric processing technology, and in particular relates to a fabric pre-loosening device. Background Technology

[0002] During fabric cutting, to ensure the final product meets size and shape requirements, pre-loosening is typically necessary when removing the fabric from the roll. This is because the fabric, due to internal stress during rolling, retains some deformation after cutting. Traditional pre-loosening involves pulling the fabric fully out and cutting it directly. However, even in this case, residual stress remains, leading to deformation in the finished product and failing to meet high-quality standards. Therefore, further processing steps are required after pre-loosening to eliminate internal stress and ensure the cut fabric achieves the ideal size and shape. Utility Model Content

[0003] The purpose of this invention is to provide a fabric pre-loosening device, which aims to solve the technical problem in the prior art that when fabric is rolled into a roll, it is affected by internal stress, which causes a certain degree of deformation after cutting.

[0004] To achieve the above objectives, this utility model provides a fabric pre-loosening device, including a feeding mechanism, a storage mechanism, and a vibration mechanism. The feeding mechanism is located on one side of the storage mechanism and is used to pull the fabric roll onto the storage mechanism. The vibration mechanism is disposed on the storage mechanism and is used to drive the storage mechanism to vibrate. The storage mechanism includes a mounting frame and a loading box. The loading box is disposed on the mounting frame and is used to load the fabric roll pulled apart by the feeding mechanism. The vibration mechanism is disposed on one side of the loading box and is used to drive the loading box to vibrate.

[0005] Furthermore, the vibration mechanism includes a vibration motor, which is connected to the loading box and is used to drive the loading box to vibrate.

[0006] Furthermore, the bottom of the loading box has a V-shaped structure.

[0007] Furthermore, the feeding mechanism includes two mounting frames, a drive assembly, a drive shaft, and a driven shaft. Two support columns extend outward from one side of the mounting frame, and the two mounting frames are respectively mounted on the two support columns. A first mounting plate and a second mounting plate are provided inside the mounting frames. The first mounting plate is located below the second mounting plate. A first bearing is provided on the first mounting plate, and a second bearing is provided on the second mounting plate. Both ends of the drive shaft are rotatably connected to the first bearing, and both ends of the driven shaft are rotatably connected to the second bearing. A gap is provided between the drive shaft and the driven shaft for the fabric to pass through. One end of the drive shaft extends outward and connects to the drive assembly, which is used to drive the drive shaft to rotate.

[0008] Furthermore, the feeding mechanism also includes two lifting cylinders, which are respectively set at the upper ends of the two mounting frames. The second mounting plate is slidably set on the mounting frame. The driving end of the lifting cylinder passes through the mounting frame and is connected to the second mounting plate. The lifting cylinder is used to drive the second mounting plate to rise or fall.

[0009] The above-mentioned technical solutions of one or more of the fabric pre-loosening devices provided in this utility model embodiment have at least one of the following technical effects: before the fabric roll needs to be cut, the feeding mechanism pulls the fabric roll open and enters the loading box. Then, the vibration mechanism causes vibration in the loading box, so that the fabric in the loading box is stress-relieved. After vibration, the fabric is fed into the cutting machine. The cut fabric will not be deformed, thus improving the pass rate of the products cut by the cutting machine. Attached Figure Description

[0018] In one embodiment of this utility model, reference is made to Figures 1-2 As shown, a fabric pre-loosening device is provided, including a feeding mechanism 100, a storage mechanism 200, and a vibration mechanism 300. The feeding mechanism 100 is located on one side of the storage mechanism 200 and is used to pull the fabric roll onto the storage mechanism 200. The vibration mechanism 300 is disposed on the storage mechanism 200 and is used to drive the storage mechanism 200 to vibrate. The storage mechanism 200 includes a mounting frame 210 and a loading box 220. The loading box 220 is disposed on the mounting frame 210 and is used to load the fabric that has been pulled apart by the feeding mechanism 100. The vibration mechanism 300 is disposed on one side of the loading box 220 and is used to drive the loading box 220 to vibrate. In this embodiment, before the fabric roll needs to be cut, the feeding mechanism 100 pulls the fabric roll open and puts it into the loading box 220. Then, the vibration mechanism 300 causes vibration in the loading box 220 to relieve the stress on the fabric inside the loading box 220. After vibration, the fabric is fed into the cutting machine. The cut fabric will not be deformed, thus improving the pass rate of the products cut by the cutting machine.

[0019] Specifically, refer to Figures 1-2As shown, the vibration mechanism 300 includes a vibration motor 310, which is connected to the loading box 220 and is used to drive the loading box 220 to vibrate. In this embodiment, the vibration motor 310 is used to drive the device box to vibrate in order to eliminate the internal stress of the fabric in the loading box 220.

[0020] Specifically, refer to Figures 1-2 As shown, the bottom of the loading box 220 has a V-shaped structure. In this embodiment, the bottom of the loading box 220 has a V-shaped structure, which makes the contact area between the box body and the fabric larger during vibration, and eliminates the stress in the fabric more quickly.

[0021] Specifically, refer to Figures 1-2 As shown, the feeding mechanism 100 includes two mounting frames 110, a drive assembly 120, a drive shaft 130, and a driven shaft 140. Two support columns 211 extend outward from one side of the mounting frame 210. The two mounting frames 110 are respectively mounted on the two support columns 211. A first mounting plate 111 and a second mounting plate 112 are provided inside the mounting frames 110. The first mounting plate 111 is located below the second mounting plate 112. A first bearing 113 is provided on the first mounting plate 111, and a second bearing 114 is provided on the second mounting plate 112. Both ends of the drive shaft 130 are rotatably connected to the first bearing 113, and both ends of the driven shaft 140 are rotatably connected to the second bearing 114. A gap is provided between the drive shaft 130 and the driven shaft 140 for the fabric to pass through. One end of the drive shaft 130 extends outward and connects to the drive assembly 120, which drives the drive shaft 130 to rotate. In this embodiment, one end of the fabric roll is placed in the gap between the drive shaft 130 and the driven shaft 140, and the fabric abuts against the drive shaft 130 and the driven shaft 140. The drive assembly 120 drives the drive shaft 130 to rotate, so that the fabric on the fabric roll is pulled open and enters the loading box 220 for internal stress relief.

[0022] Specifically, refer to Figures 1-2 As shown, the feeding mechanism 100 also includes two lifting cylinders 150, which are respectively disposed at the upper ends of the two mounting frames 110. The second mounting plate 112 is slidably disposed on the mounting frame 110. The driving end of the lifting cylinder 150 passes through the mounting frame 110 and is connected to the second mounting plate 112. The lifting cylinder 150 is used to drive the second mounting plate 112 to rise or fall. In this embodiment, when one end of the fabric roll is about to enter the gap between the drive shaft 130 and the driven shaft 140, the lifting cylinder 150 drives the driven shaft 140 to rise, facilitating the entry of the fabric. When the fabric enters between the drive shaft 130 and the driven shaft 140, the lifting cylinder 150 drives the driven shaft 140 to move towards the drive shaft 130, so that the drive shaft 130 and the driven shaft 140 press down on the fabric. When the drive shaft 130 rotates, the fabric is pulled out from the fabric roll and enters the loading box 220.

[0023] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
