Description

Technical Field

[0001] This utility model relates to the field of fabric production, and in particular to a fabric feeding storage rack. Background Technology

[0002] In the fabric processing process, it is inevitable to process both sides of the original fabric. During processing, the original fabric is often transported in a roll. After the previous roll of fabric is processed, it is often necessary to temporarily stop the machine to continue processing the next roll of fabric. Only after the new roll of fabric is connected to the end of the previous roll can the machine be restarted to continue processing, which slows down the fabric processing speed. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a material storage rack for feeding fabric.

[0004] This utility model is achieved by the following technical solution: a material storage rack for feeding fabric, including a support frame, a material storage component on the support frame, the material storage component including an upper moving part and a lower fixed part, the lower fixed part being located at the bottom of the support frame, the upper moving part being located on the crossbeam of the support frame, and the upper moving part and the lower fixed part being arranged opposite to each other;

[0005] The upper moving part moves downward along the height direction of the support frame to the lower fixed part. Before the fabric enters the processing station, it needs to be wrapped between the upper moving part and the lower fixed part. The support frame is provided with a driving component to drive the upper moving part away from or closer to the lower fixed part.

[0006] The upper movable part includes a movable beam, and the two ends of the movable beam are provided with rollers that contact the side wall of the support frame. The movable beam is driven by a drive assembly to move away from or towards the lower fixed part.

[0007] The movable beam is provided with a plurality of movable rollers on the side facing the lower fixed part. The plurality of movable rollers are rotatably connected to the movable beam and are arranged in a straight line along the length of the movable beam.

[0008] The lower fixing part includes a fixing beam, which is fixed to the bottom of the support frame and opposite to the crossbeam. The fixing beam has several fixing rollers on the side facing the crossbeam. The fixing rollers are arranged in a straight line along the length of the fixing beam, and the moving rollers and the fixing rollers correspond one-to-one.

[0009] The drive assembly is located at the bottom of the crossbeam and below the lower fixing part.

[0010] The drive assembly includes a first drive unit and a first counterweight unit. The first drive unit includes a first transmission wheel and a first transmission chain. The top of the crossbeam is rotatably connected to a first transmission wheel on the fixed beam. The first transmission chain is wound between a pair of first transmission wheels. The first transmission wheel on the fixed beam is driven to rotate by a motor through a sprocket. The first counterweight unit is fixed on the first transmission chain on one side of the first transmission wheel. The moving beam is fixed on a first steel cable on the other side of the first transmission wheel. When the first transmission chain drives the moving beam to descend, the counterweight unit rises.

[0011] The drive assembly is located above the crossbeam.

[0012] The drive assembly includes a second drive unit and a second counterweight unit. The second drive unit includes a second drive wheel and a second drive chain. The second drive wheel is fixed on the crossbeam. One end of the second drive chain is fixed on the moving beam. The second drive chain is wound around the second drive wheel and the other end of the second drive chain is fixed on the second counterweight unit. The second drive wheel is driven to rotate by the drive motor through the sprocket drive. When the second drive wheel drives the moving beam to rise, the second counterweight unit descends.

[0013] The first counterweight is provided with a guide frame on the side facing the support frame. A guide groove is opened on the column of the support frame along the height direction of the support frame, and the guide frame is inserted into the guide groove.

[0014] The support frame has guide holes on its uprights, which are arranged along the height of the support frame. The second counterweight is provided with a guide bracket on the side facing the support frame, and a guide post is provided on the guide bracket, which passes through the guide holes.

[0015] Compared to existing technologies, this invention requires multiple pairs of roller sets (one fixed roller and one corresponding movable roller, collectively referred to as a roller set) in actual use. The fabric is wound in an S-shape, sequentially wound onto the fixed and movable rollers to create fabric redundancy. When new and old fabric rolls are joined, the movable beam descends to release the redundant fabric. Simultaneously, manual joining is performed. During this joining process, subsequent fabric processing effectively utilizes the redundant fabric in the storage rack, thus enabling fabric roll changes without stopping the machine and resulting in higher fabric processing efficiency.

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0020] Reference Figure 1-2 A fabric feeding storage rack includes a support frame 1, on which a storage assembly 2 is provided. The storage assembly 2 includes an upper moving part 21 and a lower fixed part 22. The lower fixed part 22 is located at the bottom of the support frame 1, and the upper moving part 21 is located on the crossbeam 11 of the support frame 1. The upper moving part 21 and the lower fixed part 22 are arranged opposite to each other. The upper moving part 21 moves along the height direction of the support frame 1 towards the lower fixed part 22. Before the fabric enters the processing station, it needs to be wound between the upper moving part 21 and the lower fixed part 22. The support frame 1 is provided with a driving assembly 3 for driving the upper moving part 21 away from or towards the lower fixed part 22. In actual use, the fabric is wound in an S-shape between the upper moving part 21 and the lower fixed part 22, forming a redundancy of fabric. When new and old fabric rolls are joined, the moving part descends, and the descent rate is equal to the rate at which the redundant fabric is released. At the same time, manual splicing is performed. During the splicing process, the subsequent fabric processing actually utilizes the excess fabric in the storage rack, thus enabling the fabric roll to be changed without stopping the machine, resulting in higher fabric processing efficiency.

[0021] In this example, the upper moving part 21 includes a moving beam 211. Rollers 212 are provided at both ends of the moving beam 211, contacting the side walls of the support frame 1. The moving beam 211 is driven by the drive assembly 3 to move away from or towards the lower fixed part 22. Several moving rollers 213 are fixed to the side of the moving beam 211 facing the lower fixed part 22. The moving rollers 213 can be bolted to the moving beam 211. The several moving rollers 213 are rotatably connected to the moving beam 211, and are arranged in a straight line along the length of the moving beam 211. The moving rollers 213 are used to wind fabric. Rollers 212 are provided at both ends of the moving beam 211, contacting the columns 12 of the support frame 1. During the movement of the moving beam 211, the rollers serve both a limiting function, reducing the possibility of swaying during movement, and a guiding function, making the movement of the moving beam 211 more stable.

[0022] In this embodiment, the lower fixing part 22 includes a fixing beam 221, which is fixed to the bottom of the support frame 1 and opposite to the crossbeam 11. Several fixing rollers 222 are provided on the side of the fixing beam 221 facing the crossbeam 11. These fixing rollers 222 are arranged in a straight line along the length of the fixing beam 221, with each moving roller 213 corresponding to one of the fixing rollers 222. When the fabric passes through, it is actually wound between the fixing rollers 222 and the corresponding moving rollers 213 in an S-shape. If splicing is required, the drive assembly 3 can drive the moving beam 211 downwards, thereby releasing the fabric originally wound between the fixing rollers 222 and the moving rollers 213 to ensure continuous subsequent processing. During this process, splicing can be performed. That is, during the splicing operation, the subsequent fabric processing actually utilizes the redundant fabric in the storage rack, thus enabling fabric roll replacement without stopping the machine, resulting in higher fabric processing efficiency.

[0023] Based on the above embodiment, the drive assembly 3 can be located at the bottom of the crossbeam 11 and below the lower fixed part 22. In this embodiment, the drive assembly 3 includes a first drive part 31 and a first counterweight part 32. The first drive part 31 includes a first transmission wheel 312 and a first transmission chain 311. The top of the crossbeam 11 and the fixed beam 221 rotate respectively. A first transmission wheel 312 is connected, and the first transmission chain 311 is wound between a pair of first transmission wheels 312. The first transmission wheel 312 located on the fixed beam 221 is driven to rotate by a motor through a sprocket drive. The first counterweight part 32 is fixed on the first transmission chain 311 on one side of the first transmission wheel 312, and the moving beam 211 is fixed on the first steel cable on the other side of the first transmission wheel 312. When the first transmission chain 311 drives the moving beam 211 to descend, the counterweight part rises. Furthermore, a guide frame 321 is provided on the side of the first counterweight 32 facing the support frame 1. A guide groove 121 is opened on the column 12 of the support frame 1 along the height direction of the support frame 1, and the guide frame 321 is inserted into the guide groove 121. This makes the operation more stable. Although this method can achieve the purpose of continuous fabric laying without stopping the machine, it was found in actual use that the length of the transmission chain is too long, so it is easily affected by the external environment, causing the moving beam 211 to vibrate.

[0024] While the aforementioned installation method of the drive component 3 in the embodiment can achieve the purpose of continuous fabric feeding without stopping the machine, it was found in actual use that the excessive length of the transmission chain made it susceptible to external environmental influences, causing the moving beam 211 to vibrate. Therefore, this embodiment improves the installation method of the drive component 3. Specifically, the drive component 3 is located above the crossbeam 11. In this embodiment, the drive component 3 includes a second drive unit 33 and a second counterweight unit 34. The second drive unit 33 includes a second transmission wheel 332 and a second transmission chain 331. The second transmission wheel 332 is fixed on the crossbeam 11, one end of the second transmission chain 331 is fixed on the moving beam 211, and the second transmission chain 331 is wound around the second transmission wheel 332, with the other end of the second transmission chain 331 fixed on the second counterweight unit 34. The second transmission wheel 332 is driven to rotate by the drive motor through the sprocket transmission, and the second counterweight unit 34 descends when the second transmission wheel 332 drives the moving beam 211 to rise. Meanwhile, guide holes 122 are made on the uprights 12 of the support frame 1, and the guide holes 122 are arranged along the height direction of the support frame 1. The second counterweight 34 is provided with a guide bracket 341 on the side facing the support frame 1, and a guide post 342 is provided on the guide bracket 341, which passes through the guide holes 122. The overall arrangement of the drive assembly 3 reduces the amount of the second transmission chain 331, thereby reducing the possibility of chain vibration. It is more stable in actual use.

[0025] In this embodiment, the first and second counterweights only serve as counterweights and can be ordinary counterweights, such as iron or cement.

[0026] Compared to existing technologies, this invention requires multiple pairs of roller sets (one fixed roller 222 and one corresponding movable roller 213, collectively referred to as a roller set) in actual use. The fabric is wound in an S-shape, sequentially wound onto the fixed roller 222 and the movable roller 213 to create fabric redundancy. When new and old fabric rolls are joined, the movable beam 211 descends to release the redundant fabric. Simultaneously, manual joining is performed. During this joining process, subsequent fabric processing effectively utilizes the redundant fabric in the storage rack, thus enabling fabric roll replacement without stopping the machine and resulting in higher fabric processing efficiency.

[0027] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
