Description

Technical Field

[0001] This utility model relates to the field of textile fabric processing technology, specifically to an unwinding device for textile fabric processing. Background Technology

[0002] Textile fabric is the material used to make clothing. As one of the three elements of clothing, fabric can not only interpret the style and characteristics of clothing, but also directly affect the color and shape of clothing. After the finished fabric is sent to the customer, the customer will ask the fabric factory to rework the non-conforming items. The rework requires the fabric to be removed from the hollow paper core tube.

[0003] According to patent document CN104555521A, a fabric unwinding device is disclosed, including a U-shaped bottom fixing bracket, a support frame mounted on two short sides of the bottom fixing bracket, a push rod fixed on the long side of the bottom fixing bracket, and movable rollers. The support frame and the short sides of the bottom fixing bracket form a triangular structure, and an arc-shaped paper core support opening is provided at the top of the support frame. Movable rollers are provided at the same end of the two short sides of the bottom fixing bracket, and a movable roller is also provided at the middle position of its long side.

[0004] Currently, traditional unwinding equipment for textile fabric processing has a simple structure. During the unwinding process, it cannot properly handle fabric wrinkles, and the underlying fabric is prone to rolling under tension, affecting unwinding efficiency. In addition, the roller diameters are often inconsistent. If the roller diameter is smaller than the gap between adjacent shafts, the fabric may fall between adjacent shafts when the unwinding is almost complete. Utility Model Content

[0005] The purpose of this utility model is to provide an unwinding device for textile fabric processing, in order to solve the problems mentioned in the background art. The existing traditional unwinding devices for textile fabric processing have a simple structure, cannot handle fabric wrinkles well during the unwinding process, and the bottom layer of fabric is easily rolled by the tension during the unwinding process, which affects the unwinding efficiency. At the same time, the roller diameters are often different. If the roller diameter is smaller than the gap between adjacent rotating shafts, the fabric will fall between the adjacent rotating shafts when the unwinding is almost complete.

[0006] To achieve the above objectives, this utility model provides the following technical solution: It includes a base frame, a steering wheel is provided on one side of the lower end of the base frame, a support frame is provided on the upper end of the base frame, a support rod is fixedly connected to one side of the support frame, a fixed roller is rotatably connected to the inner wall of the support rod, a flattening mechanism is fixedly connected to the inner wall of the support frame, a driving mechanism is rotatably connected to the middle of the flattening mechanism, a push rod is fixedly connected to one side of the upper end of the base frame, and a directional wheel is fixedly connected to the lower end of the base frame away from the steering wheel.

[0007] The flattening mechanism includes a connecting disc, the outer side of which is fixedly connected to the inner wall of a support frame. An elastic connecting rod is provided on the outer wall of the connecting disc. An arc-shaped block is provided at one end of the elastic connecting rod. A roller is rotatably connected to the inner wall of the arc-shaped block. A U-shaped frame is fixedly connected to the open side of the arc-shaped block. Slide grooves are embedded and connected to both sides of the inner wall of the U-shaped frame. A spring is fixedly connected to one side of the inner wall of the slide groove. A slider is fixedly connected to one end of the spring. A connecting shaft is rotatably connected to the two sliders that are close to each other. A magnet is fixedly connected to the outer wall of the connecting shaft. A pressure roller is sleeved on the outer wall of the connecting shaft.

[0008] Preferably, an elastic connecting rod is fixedly connected to the outer wall of the connecting disc in an annular shape, and one end of the elastic connecting rod is fixedly connected to the inner side wall of the arc-shaped block.

[0009] Preferably, the number of elastic connecting rods, arc blocks, and rollers is set to seven sets.

[0010] Preferably, the upper end of the steering wheel is fixedly connected to one side of the lower end of the base frame, and the lower end of the support frame is fixedly connected to the upper end of the base frame.

[0011] Preferably, the drive mechanism includes a motor, the lower end of which is bolted to the bottom wall of the support frame. The output shaft of the motor is provided with a drive wheel, the outer wall of which is provided with a synchronous belt. The upper end of the synchronous belt is connected to a driven wheel, a rotating rod is inserted into the middle of the driven wheel, an unwinding roller is sleeved on the outer wall of the rotating rod, and bearings are sleeved at both ends of the rotating rod.

[0012] Preferably, the output shaft of the motor is connected to one end of the drive wheel, and the outer wall of the drive wheel is sleeved with the inner wall of the synchronous belt.

[0013] Preferably, the bearings fitted at both ends of the rotating rod are fixedly connected to the support frame and the inside of the connecting disc.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The flattening mechanism allows the equipment to exert a mutual squeezing force between the pressure rollers on both sides, thus flattening the fabric. When the fabric moves, it drives the pressure rollers to rotate, flattening the fabric as it moves away. The rolled fabric is placed within the arc-shaped block. The elastic connecting rod adapts to the radius of the rolled fabric, and the rollers within the arc-shaped block roll in contact with the rolled fabric. When one end of the rolled fabric needs to be unwound, it leaves the arc-shaped block through a notch. As the unwound amount increases, the radius of the rolled fabric decreases, and the elastic connecting rod causes the arc-shaped block to retract, ensuring the rollers remain in rolling contact with the fabric. This effectively holds the rolled fabric and prevents it from falling.

[0016] 2. The drive mechanism ensures smooth rotation of the unwinding roller, guaranteeing a seamless unwinding process. The use of a synchronous belt not only improves transmission efficiency but also reduces noise and wear. The driven pulley ensures uniform transmission, preventing fabric damage caused by uneven speed. The bearings fitted on the outer wall of the unwinding roller reduce friction and extend the equipment's lifespan. The lower end of the motor is bolted to the bottom wall of the support frame, ensuring the motor's stability and reliability. This allows the unwinding equipment to achieve efficient and stable unwinding operations, meeting the high-precision requirements of textile fabric processing. Attached Figure Description

[0023] Please see Figure 1 , Figure 2 and Figure 4 This utility model provides a technical solution: an unwinding device for textile fabric processing, including a base frame 1, a steering wheel 2 provided on one side of the lower end of the base frame 1, a support frame 3 provided on the upper end of the base frame 1, a support rod 4 fixedly connected to one side of the support frame 3, a fixed roller 5 rotatably connected to the inner side wall of the support rod 4, a flattening mechanism 6 fixedly connected to the inner side wall of the support frame 3, a driving mechanism 7 rotatably connected to the middle of the flattening mechanism 6, a push rod 8 fixedly connected to one side of the upper end of the base frame 1, and a directional wheel 9 fixedly connected to the lower end of the base frame 1 away from the steering wheel 2. The flattening mechanism 6 includes a connecting disc 61, the outer side of the connecting disc 61 fixedly connected to the inner side wall of the support frame 3, an elastic connecting rod 62 provided on the outer wall of the connecting disc 61, an arc-shaped block 63 provided at one end of the elastic connecting rod 62, and the inner side wall of the arc-shaped block 63 rotating... A roller 64 is dynamically connected. A U-shaped frame 65 is fixedly connected to one side of the opening of the arc block 63. Slide grooves 66 are embedded in both sides of the inner wall of the U-shaped frame 65. A spring 67 is fixedly connected to one side of the inner wall of the slide groove 66. A slider 68 is fixedly connected to one end of the spring 67. A connecting shaft 69 is rotatably connected to the end of the two sliders 68 that are close to each other. A magnet block 610 is fixedly connected to the outer wall of the connecting shaft 69. A pressure roller 611 is sleeved on the outer wall of the connecting shaft 69. An elastic connecting rod 62 is fixedly connected to the outer wall of the connecting disc 61 in a ring. One end of the elastic connecting rod 62 is fixedly connected to the inner side wall of the arc block 63. There are seven sets of elastic connecting rods 62, arc blocks 63 and rollers 64. The upper end of the steering wheel 2 is fixedly connected to one side of the lower end of the base frame 1. The lower end of the support frame 3 is fixedly connected to the upper end of the base frame 1.

[0024] The operator starts the motor 71. The output shaft of the motor 71 drives the driven wheel 74 to rotate via the driving wheel 72 and the synchronous belt 73. A rotating rod 75 is fixedly connected to the middle of the inner wall of the driven wheel 74 by a key, enabling the motor 71 to drive the rotating rod 75 to rotate. In use, after the motor 71 starts, it drives the rotating rod 75 to rotate via the synchronous belt 73, thereby causing the unwinding roller 76 to roll inside the connecting disc 61, realizing the unwinding of the textile fabric. At the same time, due to the presence of the flattening mechanism 6, the fabric can be kept flat during the unwinding process, avoiding wrinkles or damage. In addition, the U-shaped frame 65 allows the spring 67 to... The pressure roller 611 applies appropriate elasticity to ensure that the fabric is subjected to uniform pressure during unwinding, thereby improving the unwinding quality. The operator attaches a U-shaped frame 65 to both sides of the notch at the upper end of the arc-shaped block 63. The length of the U-shaped frame 65 is equal to the length of the arc-shaped block 63. Sliding grooves 66 are embedded on both sides of the inner wall of the U-shaped frame 65, and sliders 68 are slidably connected within the grooves 66. A connecting shaft 69 is fixed between the sliders 68 on both sides, and the pressure roller 611 is rotatably connected to the connecting shaft 69. An annular magnet 610 is interference-fitted at both ends of the connecting shaft 69. The magnets 610 on both sides magnetically attract each other, thereby... This ensures a tight fit between the two pressure rollers 611. When it's necessary to remove one end of the fabric from the arc-shaped block 63, the operator pushes the pressure rollers 611 on both sides of the U-shaped frame 65. This causes the pressure rollers 611 to push the slider 68 to move to one side within the groove 66 via the connecting shaft 69. The spring 67 is compressed by the pushing force of the slider 68 and accumulates elastic potential energy, creating a gap between the two pressure rollers 611. The fabric passes through this gap. Then, the pressure rollers 611 are released, the pushing force of the two pressure rollers 611 disappears, and the compression force on the spring 67 is released. The elastic potential energy of the spring 67 causes the pressure rollers 611 to return to their original position. The slider 68 is pushed within the groove 66 towards another set of springs 67. The springs 67 are not yet in their natural state, so they still exert a certain pushing force on the slider 68. This pushing force is transmitted to the pressure roller 611 through the slider 68 and the connecting shaft 69. There is a mutual squeezing force between the two pressure rollers 611, which allows the fabric to be squeezed and flattened by the pressure rollers 611. As the fabric moves, it can drive the pressure rollers 611 to rotate, and the pressure rollers 611 can flatten the fabric as it leaves. The structure is compact and easy to operate, which can effectively improve the efficiency and quality of textile fabric processing.

[0025] Please see Figure 1 , Figure 3 ,and Figure 4The drive mechanism 7 includes a motor 71. The lower end of the motor 71 is bolted to the bottom wall of the support frame 3. The output shaft of the motor 71 is provided with a drive wheel 72. The outer wall of the drive wheel 72 is provided with a synchronous belt 73. The upper end of the synchronous belt 73 is connected to a driven wheel 74. A rotating rod 75 is inserted into the middle of the driven wheel 74. The outer wall of the rotating rod 75 is fitted with a rewinding roller 76. Both ends of the rotating rod 75 are fitted with bearings 77. The output shaft of the motor 71 is connected to one end of the drive wheel 72. The outer wall of the drive wheel 72 is fitted with the inner wall of the synchronous belt 73. The bearings 77 fitted at both ends of the rotating rod 75 are fixedly connected to the support frame 3 and the inside of the connecting disc 61.

[0026] The gap width between the unwinding roller 76, the pressure roller 611, and the fixed roller 5 is equal to the thickness of the fabric, facilitating the smoothing of wrinkles. The fabric is pulled between the unwinding roller 76 and the pressure roller 611 to the top of the fixed roller 5. Wrinkles are smoothed by the unwinding roller 76, the pressure roller 611, and the fixed roller 5. The two pressure rollers 611 provide better smoothing. The fixed roller 5 is positioned above the support frame 3 and the pressure roller 611, facilitating increased fabric tension during unwinding. The drive mechanism 7 ensures smooth rotation of the unwinding roller 76, thereby maintaining... The use of synchronous belt 73 ensures a smooth unwinding process, which not only improves transmission efficiency but also reduces noise and wear. The driven wheel 74 ensures uniform transmission and avoids fabric damage caused by uneven speed. The bearing 77 sleeved on the outer wall of the unwinding roller 76 reduces friction and extends the service life of the equipment. The lower end of the motor 71 is bolted to the bottom wall of the support frame 3, ensuring the stability and reliability of the motor 71. This enables the unwinding equipment to achieve efficient and stable unwinding operations during operation, meeting the high precision requirements of textile fabric processing.

[0027] Working principle: First, the operator starts the motor 71. The output shaft of the motor 71 drives the driven wheel 74 to rotate via the driving wheel 72 and the synchronous belt 73. A rotating rod 75 is fixedly connected to the middle of the inner wall of the driven wheel 74 by a key, enabling the motor 71 to drive the rotating rod 75 to rotate. In use, after the motor 71 starts, it drives the rotating rod 75 to rotate via the synchronous belt 73, which in turn causes the unwinding roller 76 to roll inside the connecting disc 61, realizing the unwinding of the textile fabric. At the same time, due to the presence of the flattening mechanism 6, the fabric can be kept flat during the unwinding process, avoiding wrinkles or damage. In addition, the U-shaped frame 65 makes the fabric flat during the unwinding process. Spring 67 can apply appropriate elastic force to pressure roller 611 to ensure that the fabric is subjected to uniform pressure during unwinding, thereby improving unwinding quality. The operator attaches U-shaped frames 65 to both sides of the notch at the upper end of the arc-shaped block 63. The length of the U-shaped frames 65 is equal to the length of the arc-shaped block 63. Slide grooves 66 are embedded on both sides of the inner wall of the U-shaped frames 65, and sliders 68 are slidably connected within the slide grooves 66. A connecting shaft 69 is fixed between the sliders 68 on both sides, and pressure roller 611 is rotatably connected to the connecting shaft 69. An annular magnet 610 is interference-fitted at both ends of the connecting shaft 69, and the magnets 610 on both sides magnetically attract each other. The two pressure rollers 611 are pulled together so that they fit tightly. When it is necessary to remove one end of the fabric from the arc block 63, the operator pushes the pressure rollers 611 on both sides of the U-shaped frame 65. This causes the pressure rollers 611 to push the slider 68 to move to one side in the groove 66 via the connecting shaft 69. The spring 67 is compressed by the pushing force of the slider 68 and accumulates elastic potential energy, thus creating a gap between the two pressure rollers 611. The fabric passes through the gap. Then, the pressure rollers 611 are released, and the pushing force of the two pressure rollers 611 disappears. At this time, the compression force on the spring 67 is released, and the elastic potential energy of the spring 67 causes the pressure rollers 611 to return to their original position. 67 pushes the slider 68 to move towards another set of springs 67 in the groove 66. The springs 67 are not in their natural state, so the springs 67 still exert a certain pushing force on the slider 68. This pushing force is transmitted to the pressure roller 611 through the slider 68 and the connecting shaft 69. There is a mutual squeezing force between the two pressure rollers 611, so that the fabric can be squeezed and flattened by the pressure rollers 611 on both sides. This allows the pressure roller 611 to rotate when the fabric moves, and the pressure roller 611 can flatten the fabric that leaves. The structure is compact and easy to operate, which can effectively improve the efficiency and quality of textile fabric processing.

[0028] Then, the gap width between the unwinding roller 76, the pressure roller 611, and the fixed roller 5 is equal to the thickness of the fabric, facilitating the smoothing of wrinkles. The fabric is pulled between the unwinding roller 76 and the pressure roller 611 to the top of the fixed roller 5. The wrinkled areas of the fabric are squeezed and smoothed by the unwinding roller 76, the pressure roller 611, and the fixed roller 5. The two pressure rollers 611 provide better smoothing. The fixed roller 5 is positioned above the support frame 3 and the pressure roller 611, which facilitates increasing the tension of the fabric during the unwinding process. The drive mechanism 7 ensures that the unwinding roller 76 can rotate smoothly, thus guaranteeing a smooth unwinding process. The use of the synchronous belt 73 not only improves... The transmission efficiency is improved, noise and wear are reduced, and the driven wheel 74 ensures uniform transmission and avoids fabric damage caused by uneven speed. The bearing 77 sleeved on the outer wall of the unwinding roller 76 reduces friction and extends the service life of the equipment. The lower end of the motor 71 is bolted to the bottom wall of the support frame 3, ensuring the stability and reliability of the motor 71. This enables the unwinding equipment to achieve efficient and stable unwinding operations during operation, meeting the high precision requirements of textile fabric processing. The above is the working process of the entire device, and all contents not described in detail in this specification belong to the prior art known to those skilled in the art.
