A textile fabric storage rack with periodic unfolding function

Abstract

The present invention relates to the technical field of workshop storage equipment, and in particular to a textile fabric storage rack with a periodic unfolding function. The technical problem is that due to the long turnover time of some processes, the textile fabrics are in a wound state for a long time, and the current storage racks are not convenient for stretching and rubbing the textile fabrics when storing them, which makes the textile fabrics prone to memory deformation and stress creases and reduces their softness, resulting in poor storage effect of the storage rack on the textile fabrics. A textile fabric storage rack with a periodic unfolding function includes a frame, a handle fixed to one side of the frame, four universal wheels fixed to the bottom of the frame, and two winding rollers rotatably connected to the frame. After the textile fabrics are stored in a wound state for a certain period of time, they are unfolded and reversely wound to stretch the textile fabrics, so that the textile fabrics are not easily prone to memory deformation, thereby enhancing the storage effect of the storage rack on the textile fabrics.

DETAILED DESCRIPTION

[0034] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] Example 1: A textile fabric storage rack with periodic unfolding function, such as Figures 1-9 As shown, it includes a frame 1, one side of the frame 1 is connected to a handle 11 by bolts, and the bottom of the frame 1 is connected to four universal wheels 2 by bolts, and the universal wheels 2 are used to move the frame 1. Two winding rollers 3 are rotatably connected to the frame 1, and both winding rollers 3 are provided with mounting grooves. The winding rollers 3 are used to wind up textile fabrics. One side of the frame 1 is connected to a protective shell 4 by bolts, and the protective shell 4 is used to protect internal components. The winding roller 3 is provided with a fixing mechanism 5 for fixing the textile fabric, and the frame 1 is provided with a driving mechanism 6. The winding roller 3 is provided with a transmission assembly for driving the winding roller 3 to rotate through the driving mechanism 6.

[0036] The fixing mechanism 5 includes a worm 51, and the two worms 51 are respectively rotatably connected to the ends of the two winding rollers 3 away from the protective shell 4. Two rotating shafts 52 are rotatably connected in the two winding rollers 3. The two rotating shafts 52 in the same winding roller 3 form a group. The two rotating shafts 52 in each group are connected to a fixed roller 53 through a key groove. The two fixed rollers 53 on the same group of rotating shafts 52 form a group. The two fixed rollers 53 in the same group press against each other to fix the textile fabric. The two rotating shafts 52 in each group are connected to a worm gear 54 through a key groove on the ends away from the protective shell 4. The two worm gears 54 on the same group of rotating shafts 52 form a group. The two groups of worm gears 54 are respectively engaged with the two worms 51.

[0037] The fixed roller 53 is made of rubber.

[0038] The driving mechanism 6 includes a reduction motor 61, which is connected to the frame 1 by bolts. A sliding sleeve 62 is slidably connected to the output shaft of the reduction motor 61, and a first gear 63 is connected to the sliding sleeve 62 through a keyway. An electric push rod 64 is connected to the frame 1 by bolts, and a connecting frame 65 is connected to the telescopic rod of the electric push rod 64 by bolts. The connecting frame 65 is rotatably connected to the sliding sleeve 62.

[0039] The transmission assembly includes a first pulley 66, and the two first pulleys 66 are respectively connected to one end of the two winding rollers 3 close to the reduction motor 61 through a keyway. Two second pulleys 661 are rotatably connected to the side of the frame 1 close to the first pulley 66. A transmission belt 662 is respectively wound around the two second pulleys 661 and the two first pulleys 66. A second gear 663 is clamped on the two second pulleys 661.

[0040] First, the operator places one end of the textile fabric into the installation groove of the winding roller 3 near the handle 11, and then rotates the worm 51 on the winding roller 3, so that the worm 51 drives the two worm wheels 54 to rotate, and the rotation of the two worm wheels 54 drives the two fixed rollers 53 to rotate through the two rotating shafts 52, so that the two fixed rollers 53 of the same group are pressed against the textile fabric, thereby fixing the textile fabric, and then the operator starts the reduction motor 61, and the rotation of the output shaft of the reduction motor 61 drives the first gear 63 to rotate through the sliding sleeve 62, and then the operator controls the telescopic rod of the electric push rod 64 to extend, so that it drives the first gear 63 and the textile fabric near the handle 11 through the connecting frame 65 and the sliding sleeve 62. The second gear 663 is meshed with the first gear 63, so that the second gear 663 drives the second gear 663 to rotate. The rotation of the second gear 663 near the handle 11 will drive the winding roller 3 near the handle 11 to rotate through the two pulleys near the handle 11, the transmission belt 662 and the first pulley 66, so that the winding roller 3 starts to wind up the textile fabric, and then the textile fabric is wound and stored. After the textile fabric is wound up, the operator turns off the reduction motor 61 and controls the electric push rod 64 to reset at the same time, so that the first gear 63 is no longer meshed with the second gear 663. Then the operator pulls the other end of the textile fabric toward the winding roller 3 away from the handle 11, and fixes the textile fabric on the winding roller 3 When the textile fabric is stored in a wound state for a certain period of time in the installation groove, the reduction motor 61 is started, and the telescopic rod of the electric push rod 64 is controlled to retract, so that it drives the first gear 63 to engage with the second gear 663 away from the handle 11, so that the second gear 663 drives the winding roller 3 away from the handle 11 to rotate through the two pulleys, the transmission belt 662 and the first pulley 66 away from the handle 11, so that the winding roller 3 starts to pull the textile fabric and rewind, and at the same time, the other winding roller 3 will be pulled by the textile fabric and start to rotate in the opposite direction, so that the fabric is transferred from the winding roller 3 close to the handle 11 to the other winding roller 3. In this way, when the textile fabric is stored in a wound state for a certain period of time, it is passed through the second pulley 662 and the transmission belt 662 and the first pulley 66 away from the handle 11. By unfolding it and reversely winding it, the textile fabric is stretched, so that the textile fabric is not easy to produce memory deformation, and the storage effect of the storage rack on the textile fabric is enhanced; after the textile fabric is stretched, the reduction motor 61 is turned off and the electric push rod 64 is controlled to reset at the same time, and this is repeated. By regularly starting the reduction motor 61 and controlling the telescopic rod of the electric push rod 64 to extend and retract, the textile fabric is periodically stretched; when the textile fabric needs to be removed, the operator rotates the worm 51 on the two winding rollers 3 in the opposite direction, so that the worm 51 drives the fixed roller 53 to reset through the worm gear 54 and the rotating shaft 52, so that the fixed roller 53 no longer fixes the textile fabric, and then pulls the textile fabric to remove it.

[0041] Example 2: Based on Example 1, Figures 1-12As shown, a leveling mechanism 7 is also included, which is provided on the frame 1 and is used to level the textile fabric. The leveling mechanism 7 includes a synchronous frame 71, which is slidably connected to the frame 1, and four obliquely arranged guide bars are provided on the synchronous frame 71. The two guide bars on the synchronous frame 71 close to the handle 11 are a group, and the two guide bars on the synchronous frame 71 away from the handle 11 are a group. Four lifting frames 72 are slidably connected to the frame 1, and the bottoms of the four lifting frames 72 are respectively in contact with the four guide bars of the synchronous frame 71. The two lifting frames 72 close to the handle 11 are a group, and the two lifting frames 72 away from the handle 11 are a group. The two groups of guide bars on the synchronous frame 71 are used to squeeze the two groups of lifting frames 72 to move, and a first leveling roller 73 is rotatably connected between the two lifting frames 72 of each group. Two second leveling rollers 74 are rotatably connected to the frame 1, and the first leveling roller 73 and the second leveling roller 74 are used to guide the textile fabric.

[0042] The first leveling roller 73 and the second leveling roller 74 are both provided with guide grooves, and the guide grooves on the first leveling roller 73 and the second leveling roller 74 are used to stretch the textile fabric.

[0043] Initially, when the fabric is pulled from the winding roller 3 close to the handle 11 to the winding roller 3 away from the handle 11, it passes between the two first leveling rollers 73 and the two second leveling rollers 74. When the textile fabric needs to be wound from the winding roller 3 away from the handle 11 to the winding roller 3 close to the handle 11, the telescopic rod of the electric push rod 64 drives the synchronous frame 71 to move toward the second gear 663 through the connecting frame 65, so that a group of guide strips close to the handle 11 on the synchronous frame 71 squeezes a group of lifting frames 72 close to the handle 11 to move upward, so that the first leveling roller 73 and the second leveling roller 74 close to the handle 11 jointly press against the textile fabric. When the textile fabric needs to be wound from the winding roller 3 close to the handle 11 to the winding roller 3 away from the handle 11, the telescopic rod of the electric push rod 64 drives the synchronous frame 71 to move toward the second gear 663 through the connecting frame 65, so that the group of guide strips close to the handle 11 on the synchronous frame 71 squeezes the group of lifting frames 72 close to the handle 11 to move upward, so that the first leveling roller 73 and the second leveling roller 74 close to the handle 11 jointly press against the textile fabric. When the winding roller 3 of the handle 11 is turned, the synchronous frame 71 will squeeze a group of lifting frames 72 away from the handle 11 to move upward, so that the first leveling roller 73 and the second leveling roller 74 away from the handle 11 jointly press against the textile fabric, and at the same time, the guide grooves on the first leveling roller 73 and the second leveling roller 74 will apply a force extending to both sides to the textile fabric. In this way, when the textile fabric is transferred, the first leveling roller 73 and the second leveling roller 74 will limit the textile fabric and apply a force extending to both sides, thereby flattening the textile fabric, thereby reducing the possibility of folding of the textile fabric, and further enhancing the storage effect of the storage rack on the textile fabric; when the synchronous frame 71 is reset, the first leveling roller 73 and the lifting frame 72 are reset by gravity.

[0044] Example 3: Based on Example 2, Figures 1-16As shown, it also includes a rubbing mechanism 8, which is arranged on the lifting frame 72 and is used to rub the textile fabric. The rubbing mechanism 8 includes a first guide frame 81, and the two first guide frames 81 are respectively slidably connected between the four lifting frames 72. Two second guide frames 83 are connected to the frame 1 by bolts. A sliding plate 82 is slidably connected between the two first guide frames 81 and the two second guide frames 83. The lifting frame 72 drives the sliding plate 82 to move upward through the two first guide frames 81. A slide groove is opened on the end of the two sliding plates 82 close to the reduction motor 61, and a ventilation groove is opened in the middle of the sliding plate 82. A plurality of balls 821 are inlaid on the sides of the sliding plates 82 that are close to each other, and the two sliding plates 82 rub the textile fabrics through the balls 821 respectively. A guide sleeve 84 is connected to the side of the frame 1 close to the reduction motor 61 by bolts, and a support arm 85 is connected to the second guide frame 83 close to the guide sleeve 84 by bolts. A crankshaft 86 is rotatably connected between the support arm 85 and the guide sleeve 84. The crankshaft 86 is slidably connected to the sliding grooves of the two sliding plates 82. The bottom of the crankshaft 86 is connected to a bevel gear 87 through a keyway, and the output shaft of the reduction motor 61 is connected to a bevel gear 88 through a keyway, and the bevel gear 87 is meshed with the bevel gear 88.

[0045] The device further comprises a ventilation member 9 which is connected to the top of the sliding plate 82 between the two second guide frames 83 by means of bolts. The ventilation member 9 is used for drying the textile fabrics.

[0046] First, connect the ventilation member 9 to the drying fan. When the winding roller 3 starts to wind the textile fabric, one of the lifting frames 72 will move upward. The upward movement of the lifting frame 72 will drive the two first guide frames 81 to move upward, so that the sliding plate 82 at the bottom moves upward, so that the two sliding plates 82 can press against the textile fabric together through the ball bearings 821. When the reduction motor 61 rotates, it will drive the crankshaft 86 to rotate through the bevel gear 88 and the bevel gear 87. The rotation of the crankshaft 86 will drive the two sliding plates 82 to move back and forth in opposite directions through the slide grooves of the two sliding plates 82. In this way, the textile fabric is transferred through the two sliding plates 82. 2 drives the balls 821 to press against the textile fabric and move back and forth in opposite directions, thereby stretching the textile fabric and kneading it at the same time, thereby relieving the stress creases of the textile fabric and increasing its softness, significantly enhancing the storage effect of the storage rack on the textile fabric; while kneading, the drying fan is started, so that the dry air of the drying fan is blown toward the textile fabric through the ventilation slots of the ventilation member 9 and the sliding plate 82, thereby reducing the humidity of the textile fabric, so that the textile fabric is not easy to mold during storage; after the transfer of the textile fabric is completed, the synchronous frame 71 and the lifting frame 72 are reset, so that the first guide frame 81 and the bottom sliding plate 82 are reset by gravity.
