Description

Technical Field

[0001] The present application relates to the technical field of glass production, and in particular to a feeding control method and controller, a feeding control device and a storage medium. Background Art

[0002] In the glass production process, various raw materials for glass are usually put into a glass melting furnace to form a pile of materials, and the pile of materials is heated at high temperature so that the raw materials are melted and converted into glass liquid, and then gradually cooled and solidified into glass. When heating the pile of materials, it is often necessary to control the length of the pile of materials to ensure the quality of the final glass. For example, if the pile of materials is too long, the raw materials that have not been fully melted may be mixed into the glass liquid, so that the final glass is mixed with impurities and does not meet the quality requirements. In addition, if the length of the pile of materials changes too much, the melting speed of the pile of materials may fluctuate, resulting in uneven material quality of the glass. At present, the length of the pile of materials is mainly adjusted manually by manual observation, which relies on people's subjective judgment, is often not reliable enough, and consumes a lot of manpower and time costs.

[0003] Therefore, how to improve the reliability and efficiency of stockpile length adjustment has become a technical problem that needs to be solved urgently. Summary of the invention

[0004] The main purpose of the embodiments of the present application is to propose a feeding control method and controller, a feeding control device and a storage medium, aiming to realize an automated feeding control method, which can dynamically adjust the length of the material pile and improve the stability and efficiency of the material pile length adjustment.

[0005] To achieve the above-mentioned purpose, a first aspect of an embodiment of the present application proposes a feeding control method, which determines the lengths of at least two target stockpiles in a material processing area and obtains the initial stockpile lengths of each of the target stockpiles;

[0006] Comparing the initial stockpile length with a preset stockpile standard length threshold, obtaining a length comparison result; wherein the stockpile standard length threshold is determined by the position distribution characteristics of the target stockpile in the material processing area;

[0007] If the length comparison result indicates that the initial stockpile length is not equal to the stockpile standard length threshold, the thickness of the target stockpile is adjusted to make the initial stockpile length equal to the stockpile standard length threshold.

[0008] In some embodiments, at least two of the target material piles are evenly stacked in the first chemical material sub-region and the second chemical material sub-region of the chemical material zone;

[0009] The determining of the lengths of at least two target stockpiles in the material processing area to obtain the initial stockpile lengths of each of the target stockpiles includes:

[0010] The first transverse image acquisition module deployed in advance acquires an image of the target material pile in the second material processing sub-area from the end of the material processing area in a target transverse direction to obtain a first transverse material pile image;

[0011] The target material pile of the first material processing sub-area is imaged by a pre-deployed second transverse image acquisition module from the end of the material processing area in the opposite direction of the target transverse direction to obtain a second transverse material pile image;

[0012] The pre-deployed longitudinal image acquisition module acquires images of all the target stockpiles in the target longitudinal direction to obtain a longitudinal stockpile image;

[0013] Calculate the length of the target stockpile in each of the second material sub-areas by calculating the length of the target stockpile according to the first transverse stockpile image and the longitudinal stockpile image;

[0014] The length of the target material pile of each of the first material sub-areas is obtained by performing length calculation according to the second transverse material pile image and the longitudinal material pile image.

[0015] In some embodiments, the longitudinal image acquisition module includes a first longitudinal image acquisition module and a second longitudinal image acquisition module, and the longitudinal stockpile image includes a first longitudinal stockpile image and a second longitudinal stockpile image;

[0016] The pre-deployed longitudinal image acquisition module acquires images of all the target stockpiles in the target longitudinal direction to obtain a longitudinal stockpile image, including:

[0017] By using the first longitudinal image acquisition module, an image of the target material pile in the first chemical material sub-region is acquired to obtain the first longitudinal material pile image;

[0018] The second longitudinal image acquisition module is used to acquire an image of the target material pile in the second material processing sub-area to obtain the second longitudinal material pile image; wherein the first longitudinal image acquisition module and the second longitudinal image acquisition module are deployed in an area away from the end of the material processing area, and the first longitudinal image acquisition module and the second longitudinal image acquisition module are separated by a predetermined distance.

[0019] In some embodiments, if the length comparison result indicates that the initial stockpile length is not equal to the stockpile standard length threshold, adjusting the thickness of the target stockpile so that the initial stockpile length is equal to the stockpile standard length threshold includes:

[0020] If the length comparison result indicates that the initial stockpile length is not equal to the stockpile standard length threshold, a difference calculation is performed between the initial stockpile length and the stockpile standard length threshold to obtain a stockpile length deviation value;

[0021] Determining the number of times the pile thickness is adjusted according to the pile length deviation value, the preset initial pile thickness and the preset first thickness adjustment range;

[0022] The initial material pile thickness is adjusted according to the material pile thickness adjustment times and the first thickness adjustment amplitude, so that the initial material pile length is equal to the material pile standard length threshold.

[0023] In some embodiments, before comparing the initial stockpile length with a preset stockpile standard length threshold to obtain a length comparison result, the method further includes:

[0024] Initializing the stockpile standard length threshold specifically includes:

[0025] Calculate the distance between each target stockpile and the center position of the material processing area to obtain the stockpile center distance of each target stockpile;

[0026] The standard length threshold of the material pile of each target material pile is determined according to the material pile center distance of each target material pile; wherein the material pile center distance is positively correlated with the standard length threshold of the material pile.

[0027] In some embodiments, after determining the standard length threshold of each target stockpile according to the stockpile center distance of each target stockpile, the method further includes:

[0028] Determine the distance between the pre-deployed material pile heating module and the head end of the material-processing zone in the target transverse direction to obtain the upper limit value of the standard length of the material pile;

[0029] If the standard length threshold of at least one of the target material piles is greater than the upper limit of the standard length of the material pile, the standard length threshold of each of the target material piles is updated according to the upper limit of the standard length of the material pile, so that the updated standard length threshold of the material pile is less than or equal to the upper limit of the standard length of the material pile.

[0030] In some embodiments, the step of adjusting the thickness of the target stockpile so that the initial stockpile length is equal to the stockpile standard length threshold further includes:

[0031] Performing temperature detection on the target pile of materials to obtain the temperature of the pile of materials;

[0032] Comparing the material pile temperature with a preset material pile standard temperature threshold to obtain a temperature comparison result;

[0033] If the temperature comparison result indicates that the material pile temperature is not equal to the material pile standard temperature threshold, the thickness of the target material pile is adjusted according to a preset second thickness adjustment range so that the initial material pile length is equal to the material pile standard length threshold; wherein the second thickness adjustment range is smaller than the first thickness adjustment range.

[0034] To achieve the above-mentioned purpose, the second aspect of an embodiment of the present application proposes a controller, which includes a memory and a processor, the memory stores a computer program, and the processor implements the feeding control method described in the first aspect when executing the computer program.

[0035] To achieve the above-mentioned purpose, the third aspect of the embodiment of the present application proposes a feeding control device, which comprises: the controller according to claim 8, a chemical material tank, a feeding module, a material pile heating module, a temperature detection module, a first horizontal image acquisition module, a second horizontal image acquisition module, a first longitudinal image acquisition module and a second longitudinal image acquisition module;

[0050] First, some nouns involved in this application are analyzed:

[0051] Glass melting furnace: is an industrial equipment used to make glass, which can melt glass raw materials into liquid glass at high temperatures. Glass melting furnaces can include a furnace pool built with refractory materials, in which the glass batch is melted to form glass liquid, which is further cooled to form glass sheets after clarification, homogenization and other processes.

[0058] Figure 1 is an optional flow chart of the feeding control method provided in the embodiment of the present application. Figure 1 The method may include but is not limited to steps 101 to 103.

[0059] Step 101, determining the lengths of at least two target stockpiles in the material processing area, and obtaining the initial stockpile lengths of the respective target stockpiles;

[0060] Step 102, comparing the initial stockpile length with a preset stockpile standard length threshold to obtain a length comparison result; wherein the stockpile standard length threshold is determined by the position distribution characteristics of the target stockpile in the material processing area;

[0061] Step 103 : if the length comparison result indicates that the initial stockpile length is not equal to the stockpile standard length threshold, the thickness of the target stockpile is adjusted to make the initial stockpile length equal to the stockpile standard length threshold.

[0062] The beneficial effects of the embodiments of the present application include but are not limited to: after determining the initial stockpile length of each target stockpile, a comparison is made between the initial stockpile length and a preset stockpile standard length threshold; wherein the stockpile standard length threshold is determined by the position distribution characteristics of the target stockpile in the material processing area, thereby adaptively setting different stockpile standard length thresholds for different stockpiles; if the initial stockpile length is not equal to the stockpile standard length threshold, the thickness of the target stockpile is adjusted to make the initial stockpile length equal to the stockpile standard length threshold, thereby ensuring that all target stockpiles maintain a relatively stable shape as a whole, realizing an automated feeding control method, and improving the reliability and efficiency of stockpile length adjustment.

[0063] In step 101 of some embodiments, the target material pile refers to a material pile formed by the accumulation of glass raw materials in the material-making area. The material-making area can specifically be an area in a material-making pool. It should be noted that the material-making pool refers to a kiln pool in a glass melting furnace used to process the target material pile. The material-making pool can be specifically divided into a material-making area and a clarification area. The material-making area is an area where the target material pile is heated at high temperature. The target material pile is melted into glass liquid in the material-making area, and the glass liquid flows into the clarification area. The clarification area is an area where the glass liquid is clarified. Through the clarification process, impurities in the glass liquid can be reduced and the glass liquid can be homogenized, thereby improving the transparency and optical properties of the glass.

[0064] It should be noted that a feeding port (i.e., feeding position) is provided at one end of the material processing area. After the glass raw materials enter the material processing area from the feeding port, a target material pile is formed. The target material pile moves away from the feeding port and gradually melts into glass liquid. The length of the target material pile, i.e., the initial material pile length, refers to the distance from the feeding port to the farthest end of the target material pile. Among them, the farthest end of the target material pile refers to the end of the target material pile farthest from the feeding port.

[0065] In step 102 of some embodiments, the unit of the stockpile standard length threshold may be meters, such as 9 to 14 meters. The length comparison result is used to indicate whether the initial stockpile length is equal to the stockpile standard length threshold, or whether the initial stockpile length is not equal to the stockpile standard length threshold.

[0066] It should be noted that the position distribution characteristics of the target material pile in the chemical zone may refer to the spatial layout of each target material pile in the chemical zone. For example, a plurality of feeding modules are arranged horizontally (such as from east to west) at one end of the chemical zone, and each feeding module feeds glass raw materials into the chemical zone to form a target material pile, and each target material pile moves longitudinally (such as from south to north). The chemical zone can be evenly divided into a symmetrical first chemical sub-region and a second chemical sub-region through a longitudinal central axis, that is, the chemical zone on the east side and the chemical zone on the west side. The position distribution characteristics may refer to the distance between the target material pile and the central axis of the chemical zone. The closer the target material pile is to the central axis of the chemical zone, the smaller the corresponding standard length threshold of the material pile; the farther the target material pile is from the central axis of the chemical zone, the larger the corresponding standard length threshold of the material pile. Specifically, the above-mentioned method of determining the standard length threshold of the material pile is to make the standard length threshold of the material pile of each target material pile adapt to its melting speed. The material pile heating modules for heating the target material pile are arranged horizontally on both sides of the material processing area, so the closer the target material pile is to the two sides (i.e., away from the central axis of the material processing area), the faster its melting speed. The melting speed of the target material pile will affect the length of the target material pile. If the melting speed is faster, the standard length threshold of the target material pile will be shorter; conversely, if the melting speed is slower, the standard length threshold of the target material pile may be longer.

[0067] Specifically, the number of target material piles may be an even number, such as 6, 10 or 12, and the number of target material piles in the first chemical material sub-region and the number of target material piles in the second chemical material sub-region are equal.

[0068] In step 103 of some embodiments, it should be noted that since the target stockpile is heated at high temperature in the material-melting zone and melted into glass liquid, it is difficult to directly adjust the length of the initial stockpile, so the initial stockpile length is indirectly adjusted by adjusting the thickness of the target stockpile. For example, the thickness of the target stockpile can be adjusted by controlling the amount of material fed by the feeding module. The thickness of the target stockpile can also be adjusted by other means, not limited thereto.

[0069] See also Figure 2 In some embodiments, at least two target stockpiles are evenly stacked in the first and second sub-regions of the chemical material processing area. Step 101 may include but is not limited to steps 201 to 205:

[0070] Step 201, using a pre-deployed first transverse image acquisition module to acquire an image of a target material pile in a second material processing sub-area from the end of the material processing area in a target transverse direction, to obtain a first transverse material pile image;

[0071] Step 202, using a pre-deployed second transverse image acquisition module to acquire an image of a target material pile in the first material processing sub-area from the end of the material processing area in the opposite direction of the target transverse direction, to obtain a second transverse material pile image;

[0072] Step 203, using a pre-deployed longitudinal image acquisition module to acquire images of all target stockpiles in the target longitudinal direction, to obtain a longitudinal stockpile image;

[0073] Step 204, calculating the length of the target stockpile in each second material sub-area according to the first transverse stockpile image and the longitudinal stockpile image, and obtaining the initial stockpile length of the target stockpile;

[0074] Step 205 , performing length calculation based on the second transverse stockpile image and the longitudinal stockpile image to obtain an initial stockpile length of the target stockpile in each first material sub-area.

[0075] The advantage of this embodiment is that the first transverse image acquisition module is used to acquire images of the target material pile of the second material sub-area from the end of the material-processing area in the transverse direction of the target, and the second transverse image acquisition module is used to acquire images of the target material pile of the first material sub-area from the end of the material-processing area in the opposite direction of the transverse direction of the target, so that the images of all the target material piles in the material-processing area can be acquired clearly and completely. In addition, the longitudinal image acquisition module is used to acquire images of all the target material piles in the longitudinal direction of the target. By acquiring images of the target material piles from both the transverse direction of the target and the longitudinal direction of the target, the image of each target material pile can be acquired more clearly, and one of the multiple target material piles can be prevented from being blocked by other target material piles, so that the initial material pile length of each target material pile can be accurately calculated.

[0076] In step 201 of some embodiments, one side (e.g., the east side) of the chemical zone is close to the first chemical sub-region, and the other side (e.g., the west side) is close to the second chemical sub-region. The first transverse image acquisition module can be deployed at the end of the chemical zone close to the first chemical sub-region, so as to acquire images of the target material pile in the second chemical sub-region. It should be noted that the end refers to the end of the chemical zone away from the feeding port; for example, the feeding port is set on the north side of the chemical zone, and the end of the chemical zone refers to the south side of the chemical zone. Since the target material pile continuously moves from the feeding port to the end of the chemical zone, and melts into glass liquid and flows out of the chemical zone, the first transverse image acquisition module (and the second transverse image acquisition module) are set at the end of the chemical zone, so that the first transverse material pile image of the target material pile in the first chemical sub-region and the second transverse material pile image of the target material pile in the second chemical sub-region can be completely acquired, thereby calculating the length of each target material pile.

[0077] In step 202 of some embodiments, the second transverse image acquisition module can be deployed at the end of the chemical material area close to the second chemical material sub-area, so as to acquire images of the target material pile in the first chemical material sub-area. For example, the first transverse image acquisition module and the second transverse image acquisition module are both cameras, and the acquisition angle of the camera is limited. Therefore, two different image acquisition modules are used to acquire images of the target material piles in the first chemical material sub-area and the second chemical material sub-area, respectively, so as to obtain a clearer image of the target material pile, avoid the occlusion problem caused by a single acquisition angle, that is, avoid the problem of being unable to acquire a complete image of all target material piles using only one image acquisition module.

[0078] In step 203 of some embodiments, the longitudinal image acquisition module may be disposed at a position close to the end of the material processing area, so as to completely acquire the longitudinal stockpile images of all target stockpiles.

[0079] It should be noted that the target transverse direction is perpendicular to the target longitudinal direction. The first transverse image acquisition module, the second transverse image acquisition module and the longitudinal image acquisition module can specifically be monitoring camera devices, such as high-temperature industrial monitors. The target stockpile needs to be melted in a high-temperature environment, and the high-temperature industrial monitor can work normally in a high-temperature environment to obtain images or videos, which improves the reliability of the first transverse stockpile image, the second transverse stockpile image and the longitudinal stockpile image, thereby improving the reliability of the initial stockpile length calculated based on the above images.

[0080] Specifically, the high temperature industrial monitor may include an imaging system for collecting images (or videos) and a cooling protection system for protecting the imaging system. The cooling protection system may include a water cooling system and an air cooling system, and the cooling protection system can withstand a high temperature of 1000 degrees Celsius.

[0081] It should be noted that the first transverse material pile image, the second transverse material pile image and the longitudinal material pile image may be depth images, and the depth image has distance information of each object (such as the target material pile) in the image.

[0082] In step 204 of some embodiments, after collecting images of the target stockpile from two different directions, namely, the target transverse direction and the target longitudinal direction, image correction may be performed on the first transverse stockpile image and the longitudinal stockpile image, and then image fusion is performed, and depth calculation is performed on the fused images, thereby calculating the three-dimensional position of the target stockpile and obtaining the length of the target stockpile. Specifically, the first transverse stockpile image has distance information of the target stockpile in the second material sub-area.

[0083] In step 205 of some embodiments, length calculation is performed based on the second transverse stockpile image and the longitudinal stockpile image, which may be image fusion and depth calculation of the second transverse stockpile image and the longitudinal stockpile image. Specifically, the second transverse stockpile image has distance information of the target stockpile in the first material sub-area.

[0084] In some embodiments, a reference object may be provided in the material processing area, and the longitudinal stockpile image includes a first longitudinal stockpile image and a second longitudinal stockpile image. Step 204 may include: performing image positioning and identification on the first transverse stockpile image according to the position of the reference object to obtain a first initial stockpile length data group of all target stockpiles in the second material processing sub-area; performing image positioning and identification on the second longitudinal stockpile image to obtain the number of each target stockpile in the second material processing sub-area; performing data fusion on each initial stockpile length in the first initial stockpile length data group with each target stockpile in the second material processing sub-area, so that each target stockpile in the second material processing sub-area corresponds to each initial stockpile length. Similarly, step 205 may include: performing image positioning and recognition on the second transverse stockpile image according to the position of the reference object to obtain a second initial stockpile length data set of all target stockpiles in the first material sub-region; performing image positioning and recognition on the first longitudinal stockpile image to obtain the number of each target stockpile in the first material sub-region; and performing data fusion on each initial stockpile length in the second initial stockpile length data set with each target stockpile in the first material sub-region, so that each target stockpile in the first material sub-region corresponds to each initial stockpile length one by one. The advantage is that the initial stockpile length can be accurately matched to each target stockpile.

[0085] See also Figure 3 In some embodiments, the longitudinal image acquisition module includes a first longitudinal image acquisition module and a second longitudinal image acquisition module, and the longitudinal stockpile image includes a first longitudinal stockpile image and a second longitudinal stockpile image. Step 203 may include but is not limited to steps 301 to 302:

[0086] Step 301, using a first longitudinal image acquisition module, acquire an image of a target stockpile in a first chemical material sub-region to obtain a first longitudinal stockpile image;

[0087] Step 302, using a second longitudinal image acquisition module, capture an image of a target material pile in a second material processing sub-area to obtain a second longitudinal material pile image; wherein the first longitudinal image acquisition module and the second longitudinal image acquisition module are deployed in an area away from the end of the material processing area, and the first longitudinal image acquisition module and the second longitudinal image acquisition module are separated by a predetermined distance.

[0088] The advantage of this embodiment is that the images of the target material piles in the first material processing sub-area and the second material processing sub-area are respectively captured by the first longitudinal image acquisition module and the second longitudinal image acquisition module, so that the image of the target material pile in the material processing area can be captured more clearly and reliably, and the first longitudinal image acquisition module and the second longitudinal image acquisition module are deployed in an area far away from the end of the material processing area, so that the images of all target material piles in the material processing area can be completely captured, so as to obtain clear and complete first longitudinal material pile images and second longitudinal material pile images, thereby improving the accuracy of the initial material pile length.

[0089] In step 301 of some embodiments, the first longitudinal image acquisition module may be a camera, such as a high-temperature industrial monitor.

[0090] In step 302 of some embodiments, the predetermined distance can be adjusted according to the layout characteristics of the chemical material area. For example, the shape of the chemical material area is a rectangle, and the width of the chemical material area is 20 meters. In this case, the first longitudinal image acquisition module can be deployed on the central axis of the first chemical material sub-area, and the second longitudinal image acquisition module can be deployed on the central axis of the second chemical material sub-area. The predetermined distance between the first longitudinal image acquisition module and the second longitudinal image acquisition module can be 10 meters. The predetermined distance can also be other pre-set values, which are not limited in the embodiments of the present application.

[0091] See also Figure 4 In some embodiments, step 103 may include but is not limited to steps 401 to 403:

[0092] Step 401, if the length comparison result indicates that the initial stockpile length is not equal to the stockpile standard length threshold, a difference calculation is performed between the initial stockpile length and the stockpile standard length threshold to obtain a stockpile length deviation value;

[0093] Step 402, determining the number of times the pile thickness is adjusted according to the pile length deviation value, the preset initial pile thickness and the preset first thickness adjustment range;

[0094] Step 403 : adjusting the thickness of the initial material pile according to the number of material pile thickness adjustment and the first thickness adjustment amplitude, so that the initial material pile length is equal to the material pile standard length threshold.

[0095] The advantage of this embodiment is that the number of thickness adjustments to be made to the target material pile is determined based on the material pile length deviation value. Specifically, the number of material pile thickness adjustments is determined based on the material pile length deviation value, a preset initial material pile thickness and a preset first thickness adjustment range. Then, based on the number of material pile thickness adjustments and the first thickness adjustment range, the initial material pile thickness is adjusted to make the initial material pile length equal to the material pile standard length threshold, thereby improving the reliability of the material pile length adjustment.

[0096] In step 401 of some embodiments, the pile length deviation value may be the absolute value of the difference between the initial pile length and the pile standard length threshold.

[0097] In step 402 of some embodiments, the greater the pile length deviation value is, the more times the pile thickness is adjusted.

[0098] In step 403 of some embodiments, if the length comparison result indicates that the initial stockpile length is greater than the stockpile standard length threshold, the stockpile thickness is adjusted three times, and the first thickness adjustment amplitude is 1 mm (millimeter), then the initial stockpile thickness is adjusted three times, each time by 1 mm.

[0099] Specifically, the first thickness adjustment range may be 0.05 to 2 mm, such as 1 mm.

[0100] In some embodiments, before step 402, the feeding control method further includes: initializing the first thickness adjustment range. Specifically, initializing the first thickness adjustment range includes:

[0101] Calculate the distance between each target stockpile and the center position of the material processing area to obtain the stockpile center distance of each target stockpile;

[0102] According to the material pile center distance of each target material pile, the first thickness adjustment range of each target material pile is determined; wherein the material pile center distance is positively correlated with the first thickness adjustment range.

[0103] The advantage of this embodiment is that the closer the target material pile is to the center of the material processing area (such as the central axis of the material processing area), the lower the temperature of the target material pile is, so the adjustment range of the first thickness is smaller, which is conducive to maintaining the shape stability of the target material pile.

[0104] In some embodiments, before step 402, the feeding control method further includes: initializing the initial stockpile thickness. Specifically, initializing the initial stockpile thickness includes:

[0105] Obtain the target pulling amount of each target stockpile;

[0106] The initial stockpile thickness of each target stockpile is determined according to the target pulling amount; wherein the target pulling amount is positively correlated with the initial stockpile thickness.

[0107] The advantage of this embodiment is that the initial material pile thickness of each target material pile is determined according to the target pulling amount. If the target pulling amount is larger, the initial material pile thickness of the target material pile is larger.

[0108] It should be noted that the target stockpile is melted in the melting zone to form glass. The melting zone is an area of ​​the furnace pool of the glass melting furnace. The target pull amount refers to the speed or mass of glass pulled out of the glass melting furnace to form products (such as flat glass, glass fiber, etc.). The unit of the target pull amount can be kilograms (kg), for example 700kg.

[0109] In some embodiments, before step 102, the feeding control method may further include:

[0110] Initialize the standard length threshold of the stockpile;

[0111] Among them, the initialization of the standard length threshold of the pile includes:

[0112] Calculate the distance between each target stockpile and the center position of the material processing area to obtain the stockpile center distance of each target stockpile;

[0113] According to the material pile center distance of each target material pile, the material pile standard length threshold of each target material pile is determined; wherein the material pile center distance is positively correlated with the material pile standard length threshold.

[0114] The advantage of this embodiment is that the standard length threshold of each target stockpile is determined according to the stockpile center distance of each target stockpile, and the stockpile center distance is positively correlated with the stockpile standard length threshold, so that a suitable stockpile standard length threshold is set.

[0115] It should be noted that the material-forming area may have a bilaterally symmetrical shape, and the central position of the material-forming area may refer to the central axis (ie, the symmetry axis) of the material-forming area.

[0116] In some embodiments, after determining the standard length threshold of each target stockpile according to the stockpile center distance of each target stockpile, the feeding control method further includes:

[0117] Determine the distance between the pre-deployed pile heating module and the head end of the material treatment zone in the target transverse direction to obtain the upper limit of the standard length of the pile;

[0118] If the standard length threshold of at least one target pile of material is greater than the upper limit of the standard length of the material, the standard length threshold of each target pile of material is updated according to the upper limit of the standard length of the material so that the updated standard length threshold of the material is less than or equal to the upper limit of the standard length of the material.

[0119] The advantage of this embodiment is that the distance between the material pile heating module and the head end of the material processing zone in the target transverse direction is used as the upper limit of the standard length of the material pile, and the updated standard length threshold of the material pile is ensured to be less than or equal to the upper limit of the standard length of the material pile, thereby ensuring that each target material pile can be fully heated by the material pile heating module.

[0120] Specifically, the stockpile heating module may include a heat storage chamber and a spray gun, wherein the heat storage chamber is used to increase the heat source, and the spray gun is used to heat the pool wall of the material storage area in the material storage pool to heat the target stockpile in the material storage area. The heating temperature can be adjusted by the heat storage chamber, and the heating angle can also be adjusted by controlling the spray gun.

[0121] See also Figure 5 In some embodiments, step 103 may also include but is not limited to steps 501 to 503:

[0122] Step 501, performing temperature detection on a target stockpile to obtain the stockpile temperature;

[0123] Step 502, comparing the material pile temperature with a preset material pile standard temperature threshold to obtain a temperature comparison result;

[0124] Step 503, if the temperature comparison result indicates that the material pile temperature is not equal to the material pile standard temperature threshold, the thickness of the target material pile is adjusted according to a preset second thickness adjustment range so that the initial material pile length is equal to the material pile standard length threshold; wherein the second thickness adjustment range is smaller than the first thickness adjustment range.

[0125] The advantage of this embodiment is that after comparing the initial material pile length with the material pile standard length threshold and determining that the initial material pile length is not equal to the material pile standard length threshold, the target material pile is also subjected to temperature detection, and the material pile temperature is compared with the preset material pile standard temperature threshold. If the material pile temperature is not equal to the material pile standard temperature threshold, the thickness of the target material pile is adjusted according to a second thickness adjustment amplitude that is smaller than the first thickness adjustment amplitude, thereby taking into account the influence of temperature on the length of the target material pile and improving the reliability of the feeding control method.

[0126] It should be noted that the temperature of the stockpile will affect the melting rate of the target stockpile, thereby affecting the rate of change of the length of the target stockpile. Specifically, the higher the stockpile temperature, the faster the melting rate of the target stockpile, and the faster the length of the target stockpile changes, resulting in a more unstable shape of the target stockpile. Therefore, a smaller adjustment range is used to adjust the thickness of the target stockpile to avoid excessive single adjustment, thereby improving the stability of the target stockpile and avoiding affecting the quality of the glass; for example, if the length of the target stockpile is too long, it may cause the glass raw materials that are not fully melted in the target stockpile to leave the melting zone and mix into the glass liquid in the clarification zone, resulting in impurities in the glass produced after cooling.

[0127] In step 501 of some embodiments, the temperature of the target stockpile can be detected by a temperature sensor to obtain the temperature of the stockpile. Specifically, the target stockpile is located in the material processing area of ​​the material processing tank, and the temperature sensor can be set on the tank wall of the material processing area.

[0128] In step 502 of some embodiments, the temperature comparison result may be used to indicate that the temperature of the pile is equal to a standard temperature threshold of the pile, or that the temperature of the pile is not equal to the standard temperature threshold of the pile.

[0129] In step 503 of some embodiments, the second thickness adjustment range may be one third of the first thickness adjustment range. The second thickness adjustment range may also be set in other ways, which is not limited in the embodiments of the present application.

[0130] In some embodiments, the target stockpile is obtained by feeding the material into the material processing area by a feeding module, the feeding module includes a driving motor and a valve, the valve is slidably connected to a scraper, and the scraper is arranged perpendicular to the feeding direction;

[0131] Adjust the thickness of the target stockpile, including:

[0132] The height of the scraper of the feeding module is controlled by the driving motor of the feeding module to adjust the thickness of the target material pile.

[0133] Specifically, the feeding module also includes a silo and a pusher. The silo stores glass raw materials. The pusher puts the glass raw materials in the silo into the material processing area through a valve to form a target material pile. The scraper is slidably connected to the fixed frame of the valve. The scraper can slide up and down. The height of the scraper rises equal to the thickness of the target material pile.
