[0040] The top of the main frame 1 is fixedly installed with two groups of cotton roller driving parts 9, which are respectively in driving connection with the first cotton roller 2 and the second cotton roller 3. The cotton roller driving part 9 comprises a cotton roller driving motor 901 and a first sprocket 902 fixedly installed on the output shaft end of the cotton roller driving motor 901.

The fourth sprocket 10 is drivingly connected between the second sprocket 903 and the first sprocket 902. The top of the main frame 1 is fixedly installed with a small shaft support 11, the first small shaft 12 is rotatably installed in the small shaft support 11, and the fourth sprocket 10 is fixedly installed on the shaft end of the first small shaft 12. The fourth sprocket 10 is arranged to tighten the transmission sprocket between the two groups of first cotton rollers 2, so as to ensure smooth chain transmission.

[0041] The main frame 1 is provided with a conveying roller frame 7 on one side, which is used to convey the glass fiber cotton felt into the main frame 1. The conveying roller frame 7 comprises a bottom support 701, an inclined bracket 702 is arranged in the bottom support 701, and roller shafts 703 are equidistantly arranged in the bottom support 701 and the inclined bracket 702 and are rotatably installed. The glass fiber cotton felt is conveyed into the main frame 1 by the conveying roller frame 7.

[0042] The main rack 1 is provided with a PLC general control module 24, which is electrically connected with the belt scale 6, the swing driving motor 801 and the cotton roll driving motor 901 respectively, and the electric signal control of each electrical control device is realized through the PLC general control module 24, so that the intelligent control of the glass fiber multi-section transportation segmented weight distribution device is realized.

[0043] Exemplarily, in a glass fiber automatic packaging process, the basic requirements are: accurate weight distribution of 20 kg ± 0.1 kg; and the cotton felt is continuously and uniformly run without interruption.

[0044] In an embodiment of the glass fiber multi-section transportation segmented weight distribution device, the weight distribution device is controlled by the PLC (MCU module) in the first stage of the first cycle, and the first group of roller shafts and the second group of roller shafts are synchronously operated. By introducing the end of the cotton felt between the first group of roller shafts to pull the cotton felt along the second group of roller shafts, the cotton felt is brought into the swing cylinder to make accelerated motion, and after acceleration to the first speed, the cotton felt is uniformly run along the swing cylinder to stack on the belt scale. When the weight of the cotton felt on the belt scale exceeds the set value of 19 kg, the belt scale sends a speed change signal to the PLC (MCU module), and the first group of roller shafts and the second group of roller shafts are controlled by the PLC (MCU module) to enter the second stage of operation.

[0045] In the second stage, according to the speed change signal, the speed of the first group of roller shafts is reduced, and the speed of the cotton felt entering the first group of roller shafts is reduced to the second speed. At this time, the second speed is less than the conveying speed of the cotton felt conveying belt, and the cotton felt is accumulated in the storage area. The second speed is less than the first speed of the second group of roller shafts, and the cotton felt generates a pulling stress between the running first group of roller shafts and the second group of roller shafts. The second group of roller shafts pulls the cotton felt forward, which eventually leads to a large speed difference, resulting in a larger pulling stress. The cotton felt is intermittently broken into block-shaped cotton felt between the two groups of roller shafts and falls on the belt scale in turn. The belt scale intermittently feeds the weight condition to the PLC (MCU module) until the belt scale accurately weighs 20 kg (± 0.1 kg) (considering that there is still a part of the cotton felt that has not fallen, the threshold value of the belt scale can be appropriately adjusted to a value less than 20 kg). The PLC (MCU module) controls the first group of roller shafts and the second group of roller shafts to enter the third stage.

[0046] In the third stage, the first group of roller shafts stops running, the belt scale accurately weighs 20 kg (± 0.1 kg), and the cotton felt with the weighed weight is conveyed to the packaging conveying belt for packaging. The system completes the first cycle and sends an electric signal to the PLC (MCU module); and enters the fourth stage.

[0047] In the fourth stage, the PLC (MCU module) controls the first group of roller shafts to accelerate to the first speed. The first group of roller shafts sends the clamped cotton felt to the second group of roller shafts again, and accelerates to the first speed equal to the second group of roller shafts, and then runs at a constant speed in synchronization with the second group of roller shafts, and the system enters the first stage of the second cycle and runs repeatedly in an intermittent manner to achieve multi-section transportation and segmented weight distribution of the cotton felt.

[0048] The glass fiber multi-section transportation and segmented weight distribution device realizes segmented weight distribution to the target weight through roller shafts in steps. First, the roller shafts run at a first speed to stack the fiber cotton on the weighing scale through the swing cylinder, cut the fiber cotton when the weight approaches the target weight, and then perform a small amount of weight distribution by reducing the rotation speed of the roller shafts. The second group of roller shafts keeps the first speed unchanged, and the first group of roller shafts changes the speed to control multi-section weight distribution, so as to achieve accurate weight distribution. After multiple speed reduction and small amount of weight distribution to reach the target weight, the speed is increased again to enter the next segmented weight distribution cycle, and finally the effect of multi-section transportation and segmented weight distribution of glass fiber cotton is realized.

[0049] The application also provides a control method of a glass fiber multi-section transportation and segmented weight distribution device, which comprises the following steps:

[0050] S1, controlled by the PLC general control module 24, start the two groups of cotton pressing roller drive motors 901 to drive the two groups of first cotton pressing rollers 2 to roll and the two groups of second cotton pressing rollers 3 to roll, so that the two groups of roller shafts run synchronously. The worker introduces the end of the glass fiber cotton felt between the two groups of first cotton pressing rollers 2 to pull the glass fiber cotton felt along the second cotton pressing rollers 3, so as to bring the glass fiber cotton felt into the cotton collecting cylinder 4 and then into the swing cylinder 5 to do acceleration motion. After acceleration to V1, run at a constant speed. The glass fiber cotton felt falls on the belt scale 6 and is stacked in a shaped manner along the swing cylinder 5. When the weight of the glass fiber cotton felt on the belt scale 6 exceeds the set value 19Kg, the belt scale 6 sends an electrical signal to the PLC general control module 24, and the PLC general control module 24 controls the two groups of first cotton pressing rollers 2 and the two groups of second cotton pressing rollers 3 to enter the second stage of operation;

[0051] S2, the rotation speed of the first cotton pressing roller 2 is reduced, and the glass fiber cotton felt enters the first cotton pressing roller 2 at a reduced speed. At this time, the V1 speed is less than the conveying speed of the glass fiber cotton felt conveying roller frame 7, and the glass fiber cotton felt is stacked in the storage area. V 1第一压棉辊 <V 1第二压棉辊, the glass fiber cotton felt generates a tensile stress between the first running cotton pressing roller 2 and the second cotton pressing roller 3, the second cotton pressing roller 3 pulls the glass fiber cotton felt forward, and finally the greater the speed difference, the greater the tensile stress generated, the glass fiber cotton felt is intermittently broken into block-shaped glass fiber cotton felt between the first cotton pressing roller 2 and the second cotton pressing roller 3, and then falls on the belt scale 6, the belt scale 6 intermittently feeds the weight to the PLC general control module 24, until the belt scale 6 accurately weighs 20Kg±0.1Kg, considering that there is still a part of the glass fiber cotton felt that has not fallen down, the threshold value of the belt scale needs to be adjusted to a value less than 20Kg, and the PLC general control module 24 controls the first cotton pressing roller 2 and the second cotton pressing roller 3 to enter the third stage;

[0052] S3, V 1第一压棉辊 Stop running, the belt scale 6 completes accurate weighing of 20Kg±0.1Kg, and the glass fiber cotton felt with the weighed weight is conveyed to the packaging conveyor belt for packaging, the system completes the first cycle, and sends a signal to the PLC general control module 24, and enters the fourth stage:

[0053] S4, at the same time, the PLC general control module 24 controls the first cotton pressing roller 2 to run at V 3第一压棉辊 acceleration, the two groups of first cotton pressing rollers 2 convey the glass fiber cotton felt clamped again to the two groups of second cotton pressing rollers 3, and V 3第一压棉辊 accelerate to equal V 1第二压棉辊 running speed and V 1第二压棉辊 maintain synchronous uniform speed running, the whole glass fiber multi-section transportation segmented weighing system enters the second cycle running, and repeated intermittent running can realize multi-section transportation segmented weighing of the glass fiber cotton felt.

[0054] The control method of the glass fiber multi-section transportation segmented weighing device realizes weighing to the target weight through step-by-step segmented weighing of the roller shaft. First, two groups of roller shafts run at a first speed, the fiber cotton is stacked on the weighing scale through the swing cylinder, and the fiber cotton is cut when approaching the target weight. Then, a small amount of weighing is realized by reducing the rotation speed of the roller shaft, the second group of roller shafts remains at the first speed, the multi-section weighing is controlled by changing the speed of the first group of roller shafts, the accurate weighing is realized, and the target weight is realized after multiple speed reduction and small amount of weighing. Then, the speed is increased again to enter the next segmented weighing cycle, and finally the effect of multi-section transportation segmented weighing of the glass fiber cotton is realized.

[0055] Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions recorded in the foregoing embodiments can be modified, or some technical features can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
