The term "based on" means "based at least in part on". The term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one other embodiment", etc.

[0059] In the present application, the terms "first", "second", etc. are not used to limit the order of precedence and the number of components, unless otherwise specified. In the present application, the meaning of "multiple" refers to two or more, unless otherwise clearly and specifically defined. In addition, in the present application, unless otherwise clearly and specifically defined, the terms "installation", "connection", "attachment", etc. should be understood in a broad sense.

For those skilled in the art, the specific meanings of the above terms in this article can be understood according to the specific circumstances.

[0060] The raw materials of short glass fibers include dry chopped strands and wet chopped strands. Among them, wet chopped strands are usually used in the slurry mixing process of gypsum board. The moisture in the glass fiber can restrict the divergence of the glass fiber. In the present application, the length of the wet chopped strands can be 6-12 mm, which is not easy to fuzz and entangle. During the addition of short glass fibers, the rolled glass fibers can be cut on site and then added to the gypsum slurry. However, this method has a low efficiency in adding glass fibers and cannot achieve large flow addition.

[0061] Wet chopped glass fibers in bags can be fed into the glass fiber feeding system to deliver glass fibers to the gypsum slurry mixer. The glass fibers lose weight and fall into a hopper with a conical bottom. The glass fibers are fed to the main material mixer of the gypsum slurry through a side feeding screw at the bottom outlet of the hopper.

[0062] Since the glass fiber is a free-falling body, it will collide when it contacts the bottom outlet of the hopper or the screw, causing the glass fiber to become fluffy and form a ball. When there is too much water vapor in the glass fiber feeding system, the spherical glass fiber group will become larger, eventually causing bridges and blockages. When the outlet of the feeding system is blocked, the uniformity of subsequent glass fiber addition will deteriorate, and even cause material breakage. In addition, the enlarged glass fiber group may suddenly fall into the screw due to the increased weight, causing the machine to jam and interrupt production.

[0063] In view of this, the present application solves the above problem by changing the feeding amount accordingly based on the changes in the glass fiber conveying process. The content of the present application is explained below based on several embodiments.

[0064] refer to Figure 1 , Figure 1 1 is a schematic diagram of a glass fiber feeding system 10 related to a glass fiber feeding method, in which an embodiment of the present application can be applied. The glass fiber feeding system 10 includes a feeding bin 11 and a feeder 12. The main body of the feeding bin 11 is conical, including a feeding inlet 111 at the top and a feeding outlet ( Figure 1 In some other examples, the feeding bin 11 may be in other shapes, such as a rectangular parallelepiped that is wide at the top and narrow at the bottom. In some examples, the top of the feeding bin may be open, that is, the entire top of the feeding bin is the feeding inlet. In some examples, the top of the feeding bin may be provided with a lid, and the lid may be provided with a hole as the feeding inlet. The feeding inlet may be located in the middle part of the lid, from which the glass fiber can fall freely to the feeding outlet. The feeding inlet may also be located at the edge of the lid, and the glass fiber can slide downward along the inner wall of the feeding bin to reduce collision.

[0065] The feeding bin 11 is installed on the feeder 12. The inlet of the feeder 12 ( Figure 1The feeder 12 is connected to the feed outlet of the feed bin 11 (not shown) and is used to receive the glass fiber from the feed outlet of the feed bin 11. In some other examples, the feed bin 11 may not be in direct contact with the feeder 12. For example, an intermediate conveying device (such as a pipe or a trough) is provided between the feed bin 11 and the feeder 12. After the glass fiber is transported from the feed outlet of the feed bin to the outlet 122 of the feeder 12, the glass fiber can be supplied to the mixer of the gypsum slurry. For example, a transverse screw may be provided below the outlet 122, and the glass fiber is transported to the mixer through the screw. Or the glass fiber coming out of the outlet 122 directly enters the mixer by free fall.

[0066] A channel for conveying glass fiber is provided in the feeder 12. Figure 1 In the example, the channel of the feeder 12 is a trough 123, which delivers the glass fiber to the mixer. One end (inlet) of the trough is used to receive the glass fiber from the feeding outlet of the feeding bin, and the other end (outlet) of the trough is used to feed the glass fiber to the external mixer. Usually, the inlet of the trough 123 is higher than its outlet, which helps the glass fiber to move from the inlet of the trough to the outlet of the trough due to gravity. The outlet of the trough 123 may be inclined at an angle of 10-15° relative to the inlet. The trough 123 may be a curved curve in its extension direction, for example, the trough is disc-shaped. Figure 1 In the example of , the material trough 123 is a straight line in its extension direction. The cross section of the material trough 123 can be U-shaped, and its bottom is flat. The cross section of the material trough 123 can also be other shapes, such as V-shaped.

[0067] The glass fiber feeding system 10 also includes a sensor 13 (first sensor). The sensor 13 can be used to obtain changes in the glass fibers in the feeding bin 11. In some examples, the changes in the glass fibers in the feeding bin include changes in the weight of the glass fibers in the feeding bin, such as the mass of the glass fibers reduced in the feeding bin per unit time (such as per minute). In this case, the sensor 13 can be a weighing sensor. The sensor 13 can include a plurality of sub-weighing sensors, which are arranged on the feeder to detect weight changes in the upper feeding bin. For example, the sensor 13 can include two sub-weighing sensors arranged opposite to each other, which are arranged on opposite sides of the bracket of the feeder.

[0068] In some other examples, the change of the glass fiber in the feeding bin includes the change of the material level height of the glass fiber in the feeding bin, such as the material level height of the glass fiber reduced in the feeding bin per unit time. In this case, the sensor 13 can be a material level height sensor, which can be arranged inside the feeding bin 11.

[0069] The glass fiber feeding system 10 also includes a vibrator 14, which is used to initiate vibration of the feeder 12 so that the glass fiber is transported in the feeder 12 and transported to the outlet of the feeder 12. In some examples, the vibrator 14 is a pneumatic vibrator. The air pressure of the compressed air in the pneumatic vibrator can be adjusted to change the degree of air beating of the pneumatic vibrator. In some examples, the vibrator 14 can be a linear electromagnetic vibrator. The linear electromagnetic vibrator can include a vibration plate, an electromagnet, a suction block, an elastic sheet, a base, etc. The vibration plate is connected to the base through an elastic sheet, the suction block is fixed on the vibration plate, and the electromagnet is fixed on the base. The electromagnet is energized at a certain frequency, and the electromagnet attracts the suction block at a certain frequency to drive the vibration plate to vibrate. The use of a linear electromagnetic vibrator can achieve periodic high-frequency vibration. The linear electromagnetic vibrator produces directional vibration perpendicular to the wall of the mechanism to which the force is applied, so the force condition of the wall is good. Compared with a mechanical vibrator, a linear electromagnetic vibrator has the advantages of simple structure and long service life. The electromagnetic vibrator can be controlled by an electromagnetic controller and a frequency conversion controller to change the operating parameters of the electromagnetic vibrator.

[0070] The vibrator 14 is used in conjunction with the feeder 12 to achieve vibratory feeding. In some examples, the vibrator can apply vibration to the entire feeder. In other examples, the vibrator can apply vibration to one or more components in the feeder. Figure 1 In the example of FIG. 1 , the vibrator 14 is disposed inside the feeder 12, specifically inside the bracket of the feeder 12. The vibrator 14 may be installed at Figure 1 Near the outlet of the mid-feed bin or on the bottom / side wall of the trough 123. The vibrator 14 can be used to initiate vibration to the trough so that the glass fiber moves from one end (inlet) of the trough to the other end (outlet) of the trough.

[0071] Reference now Figure 2 , Figure 2 2 shows a flow chart of an exemplary glass fiber feeding control method 200 according to an embodiment of the present application. Any one or more steps in the method 200 may be performed by, for example, Fig.10 Electronic equipment 600, Figure 1 The method 200 can be implemented by any device in the glass fiber feeding system 10. In some examples, the method 200 can be performed by a computing device for managing a feeding system at a glass fiber feeding process. In some examples, the method 200 can be performed by a server (such as a central server or a cloud server) located in or away from the production site. The server can perform information management on the entire gypsum board production process to achieve centralized and unified management of the factory. The method 200 includes S201 to S203.

[0072] In S201, changes in glass fibers in a feeding bin are obtained, wherein the feeding bin is configured to deliver glass fibers to a feeder.

[0073] In some examples, changes in glass fiber in the feeding bin can be obtained based on the sensing data of the sensor. The sensor can be Figure 1 The sensor 13 in the feeding bin. The number of sensors can be one or more. The sensor 13 can be set in the feeding bin or in the feeder downstream of the feeding bin. The sensor 13 can sense the material level height of the glass fiber in the feeding bin or the weight of the glass fiber in the feeding bin. The change of the glass fiber in the feeding bin includes the weight difference of the glass fiber per unit time and / or the material level height difference per unit time. In some examples, the change or difference here reflects the reduction in the amount of glass fiber, such as the reduced material level height or the reduced weight.

[0074] In some examples, the amount of glass fiber (material level height and / or weight) in the feeding bin can be obtained from a controller (such as a programmable logic controller (PLC)) of a glass fiber feeding system or other process equipment, a sensor, and / or any storage device storing sensor data, and then the change of the glass fiber can be determined based on the amount of glass fiber over a period of time. For example, the device executing method 200 can read the change of glass fiber from the storage unit of the PLC of the glass fiber feeding system or other process equipment, or can receive the change of glass fiber sent by the processor of the PLC or directly by the sensor. For another example, the processor and / or sensor of the PLC can store the change of glass fiber in another storage device, and the device for executing method 200 reads the change of glass fiber from the storage device.

[0075] In S202 , the vibrator is started to vibrate the feeder so that the glass fiber is transported to the outlet of the feeder.

[0076] Vibratory feeding can be achieved by applying vibration to the feeder through a vibrator so that the glass fiber from the feeding bin is transmitted to the outlet of the feeder. The vibration of the feeder can drive the vibration of the channel in the feeder and reduce the blockage of the feeder. In some examples, the vibrator can directly vibrate the channel in the feeder, such as in Figure 1 In the process, the vibrator 14 drives the slot 123 of the feeder 12, so that the glass fibers on the slot 123 slide along the slot 123 to the outlet 122 and then are transported to the gypsum slurry mixer. In addition, the glass fibers discharged from the outlet of the feeding bin 11 are continuously collapsed and reduced, and the amount of glass fibers in the feeding bin will change.

[0077] In S203, the feeding amount at the outlet of the feeder is adjusted based on the change of the glass fiber.

[0078] In some examples, the feeding amount at the outlet of the feeder can be controlled by turning on or off the vibrator. For example, when the change of the glass fiber is too large, the vibrator can be turned off to buffer and reduce the feeding amount of the feeder. When the change of the glass fiber is too small, the number of vibrators started can be increased or the parameters of the current vibrator can be changed to increase the vibration of the feeder to increase the feeding amount output by the feeder. In some other examples, the vibrator can work continuously so that the feeder keeps vibrating and feeding. In this case, the feeding amount at the outlet of the feeder can be adjusted by changing the operating parameters of the vibrator to achieve fine adjustment of the feeding amount. S203 is based on the feedback of the glass fiber changes in the feeding bin upstream of the feeder to adjust the feeding amount of the feeder. Unlike setting the feedback of glass fiber changes on the vibrating feeder or downstream thereof to adjust the feeding amount, S203 can improve the accuracy of glass fiber adjustment.

[0079] In method 200, glass fiber is delivered to the feeder through the feeding bin, and the feeder transmits the received glass fiber to the downstream gypsum slurry mixer. In addition, the vibrator is used to make the feeder vibrate and feed, which can reduce the situation of glass fiber blocking or insufficient material. In addition, the feeding stability of the feeder can be improved by adjusting the feeding amount of the feeder by obtaining the change of glass fiber in the feeding bin, thereby achieving continuous feeding.

[0080] Figure 3 The flowchart of a method 300 for adjusting the feeding amount according to an embodiment of the present application is shown. The method 300 includes S301-S304.

[0081] In S301, a set value of a change in glass fiber is obtained.

[0082] In some examples, the set value of the change of glass fiber is affected by the production process of gypsum board. For example, in the mixing process of gypsum slurry, the addition flow rate of glass fiber is required to be 5.3 kg / min. In this case, the set value of the change of glass fiber in the feeding bin can be determined to be -5.3 kg / min. The set value of the change of glass fiber can be read from the storage unit of the PLC of the glass fiber feeding system or other process equipment, or another storage device.

[0083] In S302, a test value of a change in glass fiber is obtained.

[0084] The test value of the change of the glass fiber can be obtained based on the sensing data of the sensor. For example, the weight of the glass fiber measured by the weighing sensor at time t1 and time t2 is g1 and g2 respectively. In this way, the test value of the change of the glass fiber is (g2-g1) / (t2-t1).

[0085] In some examples, when the change of the glass fiber is characterized by the material level height, the set value of the change of the glass fiber can also be represented by the material level height difference. Correspondingly, the test value of the change of the glass fiber can be the ratio of the material level height difference to the time period.

[0086] In some examples, the sensor may continuously detect the glass fiber over a period of time, and the test value of the change in the glass fiber may include the change during the period of time.

[0087] In S303, the operating parameters of the vibrator are obtained.

[0088] In some examples, the operating parameters of the vibrator may include one or more of load, vibration frequency, and amplitude. The amplitude of the vibrator is determined by the air gap between the electromagnet and the suction block. The amplitude of the vibrator may be between 1 mm and 3 mm. The vibration frequency of the vibrator may be adjusted by adjusting the current in the electromagnet coil. The vibration frequency may be between 10 Hz and 60 Hz.

[0089] In some examples, the feed amount in the feeder, which can also be referred to as the moving speed of the glass fiber in the feeder, is positively correlated with the amplitude and / or frequency of the vibrator. The feed amount of the feeder can be adjusted by adjusting the operating parameters of the vibrator.

[0090] In S304 , the operating parameters are adjusted based on the difference between the set value and the test value.

[0091] In some examples, the operating parameters of the vibrator can be adjusted based on the relative size of the set value and the test value. For example, when the test value is less than the set value, the current amplitude and frequency can be increased by an electromagnetic controller and a frequency conversion controller to increase the amplitude and vibration frequency of the vibrator near the feeder, thereby increasing the amplitude and frequency of the vibration of the feeding channel in the feeder. In this way, the glass fibers in the feeding channel become looser and are transported to the discharge port faster to enter the slurry mixer. When the test value is greater than the set value, the current amplitude and frequency can be reduced by an electromagnetic controller and a frequency conversion controller to reduce the amplitude and vibration frequency of the vibrator near the feeder, thereby reducing the amplitude and frequency of the vibration of the feeding channel in the feeder. In this way, the glass fibers in the feeding channel are transported to the discharge port more slowly to reduce the feeding amount.

[0092] In some examples, a PID algorithm can be used to adjust the operating parameters of the vibrator. The test value of the real-time change of the glass fiber obtained in S302 can be input into a control unit based on the PID algorithm. The control unit based on the PID algorithm can compare the actual change of the feedback with the preset change, and calculate the error between the two. Then, the operating parameters of the electromagnetic vibrator are automatically adjusted through the PID algorithm to reduce this error, and finally the actual vibration state of the channel of the feeder is close to the preset target state. In this way, a closed-loop feedback control system is formed, which can realize real-time active and precise regulation of glass fiber feeding.

[0093] For example, the proportional, integral and differential parameters of the PID controller can be determined based on the rate of change of the current test value and the set value. These adjustments are then input into the PID controller to dynamically optimize the output amplitude and vibration frequency of the electromagnetic vibrator, so that the actual vibration state of the feeder channel is as close to the preset target state as possible. Ultimately, the feed rate at the feeder outlet is controlled to achieve continuous and stable feeding, and the feeding accuracy can be guaranteed. The feeding accuracy of the feeder can be within ±1%.

[0094] Figure 4a A perspective view of a feeder 12 according to one embodiment of the present application is shown. Figure 4b Shows Figure 4a A front view of the feeder 12. Figure 4c Shows Figure 4b Cross-sectional view of the middle feeder in the AA direction.

[0095] The feeder 12 includes a top plate 127, which can serve as a base for the feeding bin 11. The feeder also includes a telescopic sleeve 125 located between the feeding bin and the trough. The telescopic sleeve 125 connects the feeding outlet of the feeding bin and the entrance of the trough. When the trough vibrates, the glass fibers on the trough are transported downstream. The transportation of the glass fibers on the trough will cause the glass fiber piles discharged from the feeding bin near the entrance of the trough to collapse continuously. In some examples, the telescopic sleeve 125 can be tubular. In some other examples, the telescopic sleeve can be in the shape of a shovel. The telescopic sleeve 125 can be used to adjust the distance between the feeding outlet and the entrance end of the trough, and can guide the glass fibers to fall into the trough.

[0096] In some examples, a heating device may be provided at the bottom of the trough to heat the bottom of the trough. For example, the bottom of the outside of the trough 123 may include a heating device 128. The heating device 128 may be a heating plate. Since the moisture content in the wet chopped glass fibers is relatively high, the heating plate may be used to dry the bottom of the trough to prevent the water-containing glass fibers from adhering to the bottom of the trough. In some examples, the temperature of the heating device 128 is controllable.

[0097] The vibrator 14 is installed in the feeder 12. The feeder 12 includes a bracket 1261 arranged horizontally and a bracket 1262 arranged vertically. The brackets 1261-1262 together constitute a bracket supporting the vibrator 14. The bracket 1262 is suspended inside the feeder 12, and the bracket 1261 is a distance away from the bottom of the feeder. The vibrator 14 is connected to the inlet end of the trough. Because the vibrator 14 is suspended, it can only apply vibration to the trough 123 of the feeder 12 without affecting other components in the feeder 12. In addition, the feeder 12 may also include a buffer device, such as a silicone shock-absorbing block installed under the top plate 127, which can reduce the impact of the vibrator on other components.

[0098] In some examples, a guide plate may be provided on the trough, and the angle of the guide plate is adjustable, which can be used to change the thickness of the glass fiber on the trough. For example, a guide plate 124 is provided inside the trough 123. The guide plate 124 is a rectangular plate, wherein the long side contacts the surface of the trough 123, and the guide plate remains in a vertical state. One end of the guide plate 124 is close to the entrance of the trough 123, and the other end is close to the outlet of the trough 123. The angle between the guide plate 124 and the side wall of the trough 123 is adjustable. The inclination angle of the guide plate can be determined according to the size of the required feeding amount. For example, when the feeding amount of the feeder 12 is small, if the angle of the guide plate 124 is parallel to the side wall of the trough, the thickness of the glass fiber on the trough is low, and the glass fiber is relatively dispersed. Glass fiber retention will occur at the outlet 122 of the trough. At this time, if the angle of the guide plate 124 is changed, such as increasing the angle between the guide plate 124 and the adjacent side wall, the path of the glass fiber on the trough becomes narrower, and the thickness of the glass fiber increases, so that the glass fiber will not be retained at the outlet 122.

[0099] The method 200 may further include steps S211 - S212 of adjusting the guide plate according to the feed amount.

[0100] In S211, the feeding amount is obtained.

[0101] The feeding amount can be a set value of the feeding amount determined in advance, or a value detected by a sensor, such as the change in the weight of the glass fiber in the feeding bin detected by a weighing sensor, or the change in the flow rate of the glass fiber detected by a flow sensor on the trough.

[0102] In S212, the glass fiber thickness on the trough is adjusted based on the feed amount.

[0103] In some examples, the glass fiber thickness is adjusted by a guide plate. When the feed amount is small, the glass fiber thickness on the trough can be increased by increasing the angle of the guide plate. When the feed amount is large, the glass fiber thickness on the trough can be reduced by reducing the angle of the guide plate. In other examples, multiple parallel channels can be set on the feed trough, and the glass fiber thickness can be adjusted by controlling the number of channels opened.

[0104] Figure 5a A front view of a feeding bin 11 according to an embodiment of the present application is shown. Figure 5b Shows Figure 5a The cross-sectional view of the mid-feed silo in the AA direction. Figure 5a In the embodiment, the feeding bin 11 includes a main body 110, which is a conical structure that is wide at the top and narrow at the bottom. It is understood that the structure of the main body 110 is not limited thereto. In some other examples, the main body 110 may be a four-sided cone. The inner wall surface of the main body 110 is smooth, and the angle of the inner wall may be greater than 60 degrees to facilitate the glass fiber on the inner wall to slide off. A heating device may be installed around the main body to heat the side walls of the main body to prevent the glass fiber from being retained on the inner wall of the main body.

[0105] A cover 114 is provided on the top of the feeding bin 11, and a hole is provided on the surface of the cover 114 as an inlet 111 for feeding. An exhaust port 112 may also be provided on the surface of the cover 114. The exhaust port 112 may discharge harmful gases and impurities generated during the transportation and processing of glass fibers to the outside for processing, thereby reducing air pollution and preventing them from being inhaled by the human body. In some examples, a filter and a fan may also be provided near the exhaust port 112 to facilitate the discharge of gas.

[0106] The feeding outlet 113 at the bottom of the feeding bin 11 is a flange structure, which can be directly inserted into the base of the feeder. The inside of the feeding bin 11 can include a decompression device to reduce the glass fiber density at the outlet of the feeding bin. Figure 5b As shown, the decompression cone 115 extends from the top feeding inlet to the bottom feeding outlet of the feeding bin 11. The decompression cone 115 can reduce the packing density of the glass fiber at the feeding outlet of the feeding bin 11 to reduce material blockage. The feeding bin 11 also includes a cross bar 116 of the decompression cone 115.

[0107] In some examples, a stirring device (not shown) may be provided at the bottom of the feeding bin 11 to stir the glass fibers near the feeding outlet. The stirring device may be a stirring rod with an arc that can rotate around the vertical direction to make the glass fibers entering the feeder more uniform.

[0108] In some examples, the feeding inlet of the feeding bin 11 can receive the feeding from another bin. The bin can become the feeding bin. The glass fiber enters the feeding bin from the feeding bin and then enters the feeder. The feeding bin can serve as an intermediate bin to buffer.

[0109] Figure 6a A front view of a feeding bin 15 according to an embodiment of the present application is shown. Figure 6bThe top view of the feeding bin 15 of one embodiment of the present application is shown. The feeding bin 15 includes a main body 150, which is a conical structure that is wide at the top and narrow at the bottom. It is understood that the structure of the main body 150 is not limited thereto. In some other examples, the main body 150 can be a four-sided cone.

[0110] The top of the feeding bin 15 is an open structure that can receive a large flow of glass fibers. In some examples, a material bag can be used to feed short glass fibers into the feeding bin 15 from the top. The material bag can be moved by a hoist. The hoist can be started to hoist the material bag filled with short glass fibers from the ground to the top of the feeding bin 15. Then the material bag is opened so that the short glass fibers fall into the feeding bin 15 due to their own gravity. The use of material bags to transport short glass fibers can avoid the problem of difficulty in feeding due to the large specific gravity of short glass fibers. In addition, the short glass fibers are packed in bags, and there is no relative movement, so they will not fluff.

[0111] The feeding bin may include a weighing sensor (second sensor) for detecting the weight of the glass fiber fed into the feeding bin, that is, the weight of the glass fiber flowing through the feeding bin. Detecting the feeding amount of the feeding bin is conducive to fine production management. Figure 6a-6b As shown, the feeding bin 15 includes a group of four weighing sensors 151, which are evenly arranged around the top of the feeding bin 15. Each weighing sensor 151 is fixed by a corresponding support ear 152.

[0112] The feeding bin 15 also includes a vibrator 153 disposed on the outer wall, which is used to initiate vibration feeding of the feeding bin 15. There can be two vibrators, which are disposed on opposite sides. The vibrator 153 is turned on when the feeding bin is started, which can prevent the glass fiber from bridging inside the feeding bin 15 and avoid material blockage. In some examples, the vibrator 153 is a pneumatic vibrator.

[0113] A valve 154 may be provided at the bottom of the feeding bin 15 to open and close the feeding bin 15 to control the feeding of the feeding bin and stop feeding of the feeding bin. In some examples, the valve 154 may be a pneumatic butterfly valve.

[0114] In some examples, the interior of the feeding bin may include a material uniformity device for making the glass fibers in the feeding bin fluffy. Figure 7The schematic diagram of the structure of a material uniform device 155 of an embodiment of the present application is shown. The material uniform device 155 includes a rotating shaft 1551 and comb-like components 1552a, 1552b. The rotating shaft 1551 can rotate under the drive of a motor. The comb-like components 1552a, 1552b are used to rotate along the rotating direction of the rotating shaft. The comb-like components 1552a, 1552b each include stainless steel round rods of different lengths. The smooth surface of the stainless steel round rods will not destroy the original shape of the short glass fibers, thereby avoiding fuzzing. The comb-like components 1552a, 1552b include a first subcomponent 1552a and a second subcomponent 1552b arranged up and down. The tooth spacing of the first subcomponent 1552a is greater than the tooth spacing of the second subcomponent 1552b. In this way, the arrangement in which the coarse comb-like structure is located at the top and the fine comb-like structure is located at the bottom can grade and loosen the glass fibers.

[0115] In some examples, the material uniformity device may include relatively arranged rotating devices, and movable short rods are evenly arranged on the circumference of the rotating devices. When the rotating devices rotate, the short rods on the circumference thereof are driven to move. When the glass fiber falls from the top of the rotating device to the bottom, the multiple short rods will break up the glass fiber that they come into contact with, causing it to fall into the feeding bin below.

[0116] Figure 8 The flowchart of a control method 400 for a feeding bin according to an embodiment of the present application is shown. The method 400 includes S401-S405.

[0117] In S401, the feeding bin is started.

[0118] The glass fiber in the form of a bag can be put into the feeding bin, then transported to the feeder through the intermediate buffer feeding bin, and finally sent to the gypsum slurry mixer. In some examples, starting the feeding bin can include sending an instruction to open the valve at the outlet of the feeding bin. In some examples, when the feeding bin is started, the vibration applied to the feeding bin can be started. For example, an instruction to start the vibration can be sent to a pneumatic vibrator installed on the feeding bin.

[0119] In S402, the feeding amount of the feeding bin to the feeding bin is obtained.

[0120] In some examples, the weight of the glass fiber conveyed downward to the feeding bin can be obtained from a weighing sensor on the feeding bin. In some embodiments, the weight of the received glass fiber can also be obtained from a weighing sensor on the feeding bin.

[0121] In method 400 , whether it is necessary to continue to transport glass fibers downstream from the feeding bin may be determined based on the feeding amount of the feeding bin.

[0122] For example, in S403, the feed amount is compared with the feed preset value M. T .

[0123] Considering the strength requirements of the board, different types of gypsum boards have different glass fiber contents. T It can be determined according to the specific parameters of the gypsum board produced. The parameters of each gypsum board correspond to different proportions of gypsum slurry. The proportion of gypsum slurry corresponds to the flow rate of glass fiber delivered to the mixer, such as the weight of glass fiber within a certain period of time.

[0124] When the feed amount meets the preset value requirement, it indicates that the glass fiber required by the downstream is sufficient, and the process proceeds to S404; otherwise, the process proceeds to S405.

[0125] In S404, when the feeding amount is greater than or equal to the feeding preset value M T In S405, when the feeding amount is less than the feeding preset value M, T When the feeding amount is insufficient, the feeding amount is continued. During the feeding process, the feeding amount is continuously monitored, that is, the process returns to S402. This cycle is repeated until the feeding amount meets the requirements of the preset feeding value. By monitoring the feeding amount to adjust the state of the feeding bin, the feed breakage can be reduced, and the proportion of the working time of the glass fiber falling from the feeding bin into the feeding bin due to weight loss can reach more than 90%.

[0126] The feeding silo is an intermediate silo, in which the glass fibers are accumulated at the outlet at the bottom and transported to the feeding channel of the feeder. When the glass fibers in the feeding channel are transported to the downstream process link, the glass fibers accumulated at the bottom of the feeding silo will collapse, and the amount of glass fibers inside the feeding silo will also change accordingly. In some examples, the amount of glass fibers in the feeding silo can be monitored to control the device in the feeding silo or send a material level warning message. For example, the amount of glass fibers therein can be obtained from a sensor provided on the feeding silo. It can be determined whether the material uniformity device in the feeding silo needs to be started based on the amount of glass fibers obtained.

[0127] Fig. 9 The flowchart of a control method 500 for a feeding bin according to an embodiment of the present application is shown. The method 500 includes S501-S506.

[0128] In S501, the material level height of the glass fiber in the feeding bin is obtained.

[0129] The amount of glass fiber in the feeding bin can be the weight of the glass fiber or the material level height. The amount of glass fiber can be obtained by a weighing sensor or a material level height sensor arranged on the feeding bin. In S501, the material level height is used to characterize the amount of glass fiber.

[0130] In S502, it is determined whether the material level of the glass fiber is between the first threshold value H1 and the second threshold value H2.

[0131] The first threshold value H1 and the second threshold value H2 define the height range of the intermediate material level in the feeding bin. The first threshold value H1 is less than the second threshold value H2. The material level height within this range indicates that the amount of material in the feeding bin is appropriate and can provide enough glass fiber to the feeder. If the conditions are met, enter S503; otherwise, enter S504.

[0132] In S503, the material homogenizing device is started.

[0133] When the material level of the glass fiber in the feeding bin is within the range of the intermediate material level, the material uniformity device is activated. The material uniformity device may be a material uniformity device in the feeding bin. In some examples, the material uniformity device may also be a stirring device in the feeding bin. The material uniformity device enables the glass fiber to be uniformly transported to the downstream process.

[0134] In S504, determine whether the material level of the glass fiber exceeds the second threshold value H2. If the result is yes, it indicates that the amount of glass fiber in the feeding bin has exceeded the upper limit, then enter S505 and turn off the material uniformity device. If the result is no, it indicates that the amount of glass fiber in the feeding bin has fallen below the lower limit, then enter S506 and send an alarm message to prompt refilling. According to the alarm message, the feeding of the feeding bin can be increased. For example, multiple glass fiber bags are hoisted and placed in the feeding bin to feed the feeding bin.

[0135] refer to Fig.10 , Fig.10 A schematic diagram of an electronic device 600 according to an embodiment of the application is shown. The electronic device 600 includes a processor (e.g., a central processing unit (CPU)) 601 and a memory 602 coupled to the processor 601.

In some examples, the controller may be the processor 601.

The display device is also communicatively coupled to the control unit 16, and may be, for example, a touch screen, a liquid crystal display, or the like.
