Description

Technical Field

[0001] The invention belongs to the technical field of glass sorting, and in particular relates to a waste glass sorting device and a sorting method thereof. Background Art

[0002] Glass is an amorphous inorganic non-metallic material. It is generally made of a variety of inorganic minerals (such as quartz sand, borax, boric acid, barite, barium carbonate, limestone, feldspar, soda ash, etc.) as the main raw materials, and a small amount of auxiliary raw materials. Glass is widely used in buildings to block wind and let light in. It is a mixture. There is also colored glass that is mixed with certain metal oxides or salts to show color, and tempered glass made by physical or chemical methods. Glass products can be reused many times without losing quality, but there are often higher standards for glass fragments used to make new products. Therefore, when the recycled waste glass needs to be processed again for reuse, the broken waste glass needs to be sorted.

[0003] Chinese invention patent CN113926728B provides a glass sorting device and method, wherein the glass sorting device includes: a loading robot, a conveyor line, at least two receiving channels, and a servo motor, each receiving channel includes a receiving module and a receiving box, and the conveyor line is perpendicular to each receiving channel; the loading robot is used to transport the glass that has completed quality inspection to the conveyor line; the glass sorting device has low sorting efficiency and poor sorting effect.

[0004] Chinese invention patent CN109351683B relates to an automated glass sorting and processing equipment and a glass sorting and processing method, including a bottom plate, a water removal device, a screening device, and a cleaning device. The number of the water removal devices is two, and the water removal devices are symmetrically installed on the upper end surface of the bottom plate, the screening device is installed on the middle upper end surface of the bottom plate, and the cleaning device is installed on the upper end surface of the right side of the bottom plate; the sorting and processing equipment is difficult to operate and cannot meet the needs of batch processing and production.

[0005] When waste glass is conveyed backward on the feeding belt, if the waste glass is too large and is between two color sorters, and the two color sorters have different color sorting data for the same piece of waste glass, the prior art cannot adjust the size of the wind force ejected from the nozzle according to the size of the waste glass, thereby reducing the sorting accuracy and efficiency of the waste glass.

[0006] Furthermore, when waste glass is stacked above the feeding belt, the stacked waste glass interacts with each other to produce color differences, which reduces the sorting accuracy of the waste glass by the color sorter and increases the difficulty of subsequent wind zoning and sorting of the waste glass.

[0007] Impurities are easily attached to the outer surface of waste glass, and the existing technologies lack the effect of scraping and cleaning the impurities. When the impurities adhere to the outer surface of the feed belt and are continuously conveyed along with the feed belt, the impurities will not only pollute the waste glass, but also affect the color sorting accuracy of the color sorter for the waste glass.

[0022] The sorting method of the waste glass sorting device as described above comprises the following steps:

[0023] S1. When the waste glass reaches the bottom of the central plate, the waste glass contacts the rubber stopper and drives the trapezoidal swing arm to twist the torsion spring seat to rotate, and the angle value detected by the angle sensor increases to the preset angle value. When the time for the angle value detected by the angle sensor to reach the preset angle value increases, the opening area of ​​the electromagnetic flow valve increases, and the amount of gas sprayed from the nozzle increases;

[0025] S3. When the angle value detected by the angle sensor is greater than the preset angle value, the electric push rod starts to extend and drives the trapezoidal swing rod below to move downward, the extrusion force exerted by the trapezoidal swing rod on the right sliding baffle rod is reduced, the blocking area of ​​the right exhaust hole by the sliding baffle rod on the right side is reduced, the air volume discharged from the exhaust hole on the right side is increased, and the stacked waste glass is pushed in the opposite direction in cooperation with the rubber baffle rod;

[0026] S4. When impurities are adhered to the outer surface of the feeding belt and the impurities reach the bottom of the center plate, the electric push rod starts to extend and drives the trapezoidal swing arm to move downward to the maximum distance. The bottom of the trapezoidal swing arm and the top of the feeding belt are squeezed and contacted with each other. The trapezoidal swing arm swings to the right to the maximum angle and blocks the exhaust hole on the right. The air volume inside the exhaust hole on the left increases and cooperates with the rubber baffle rod to scrape and blow away the impurities.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. This application sets up the mutual cooperation of the unloading component, transmission component, color inspection component and partition component. The device has high sorting accuracy, high sorting efficiency and good sorting effect, which can meet the sorting needs of different waste glass. It is simple to operate, highly controllable and adjustable, stable and efficient, and highly adaptable. It can meet the needs of different working states and is suitable for mass production needs.

[0029] 2. This application sets up a color sorter, an electromagnetic flow valve, a nozzle and other components to cooperate with each other. The device can adjust the position of waste glass of different sizes, and adjust the amount of gas sprayed from the nozzle accordingly based on the color sorting results of the color sorter to ensure that all waste glass can reach the appropriate area for recycling and treatment.

[0030] 3. The present application sets an angle sensor and a trapezoidal swing arm and other components to cooperate with each other. When the waste glass is in a stacked state, the height change of the trapezoidal swing arm is used to apply a reverse thrust to the waste glass located above, thereby ensuring that the stacked waste glass is separated from each other, effectively improving the subsequent color sorting and categorizing sorting effect.

[0031] 4. The present application sets up the cooperation between the feeding belt and the exhaust holes and other components. If some impurities adhere to the outer surface of the feeding belt, the trapezoidal swing arm will move further downward and squeeze and contact the outer surface of the feeding belt, and cooperate with the increase in the amount of gas discharged from the left exhaust hole, thereby effectively improving the cleaning effect of the adhered impurities and effectively avoiding the impact on the subsequent color sorting and categorization of waste glass.

[0044] The unloading component 1 includes an unloading frame 101, which is tilted and is located at a low position near the end of the transmission component 2. The waste glass above the unloading frame 101 moves downward to the top of the transmission component 2 for subsequent transmission color inspection and partition recovery processes. The bottom of the unloading frame 101 is evenly arrayed with a plurality of elastic bottom plates 106. The elastic bottom plates 106 themselves are elastic. Therefore, the unloading frame 101 can vibrate elastically above the elastic bottom plates 106, further improving the unloading rate of the waste glass above the unloading frame 101. A collecting hopper 102 is provided on the top of the unloading frame 101. A bottom hole 103 is provided at the bottom of the collecting hopper 102. The bottom output end of the hole 103 is directly opposite to the top of the pouring frame 101, so the broken waste glass enters the collecting bucket 102 and falls along the bottom hole 103 to the top of the pouring frame 101 for pouring. A support plate 104 is provided on the top of the pouring frame 101 and close to the side of the center plate 301. A plurality of vibration motors 105 are evenly arrayed on the top of the support plate 104. The vibration motor 105 works and drives the pouring frame 101 to vibrate through the support plate 104. The pouring frame 101 is continuously vibrated with the elastic support of the elastic bottom plate 106 at the bottom, thereby improving the pouring process of the waste glass above the pouring frame 101 to the top of the transmission assembly 2.

[0045] The transmission assembly 2 includes a support frame 201, which is internally transmission-connected with a feed belt 212. The position of the support frame 201 will not change. A support rod 202 is provided on the top of the support frame 201, and a control panel 203 is provided on the top of the support rod 202. The control panel 203 electrically controls various electrical components. A plurality of legs 204 are evenly arrayed at the bottom of the support frame 201, and a buffer pad is provided at the bottom of the legs 204. The arrangement of the legs 204 ensures the uniformity of the height of the support frame 201. A side panel 205 is provided on the outer wall of the support frame 201, and a drive motor 206 is provided on the top of the side panel 205. A transmission shaft 207 is provided on the output end of the drive motor 206, and a drive wheel 208 is provided on the outer surface of the drive shaft 207. When the drive motor 206 starts, it drives the drive shaft 207 to rotate, and the drive shaft 207 rotates and drives the drive wheel 208 to rotate.

[0046] The inner wall of the support frame 201 is rotatably connected to a driving shaft 211 through a bearing. One end of the driving shaft 211 passes through the support frame 201 and a driven wheel 210 is provided on the outer surface. The outer surfaces of the driving wheel 208 and the driven wheel 210 are transmission-connected to a conveyor belt 209. The driving wheel 208 rotates through the conveyor belt 209 to drive the driven wheel 210 to rotate, and the driven wheel 210 drives the driving shaft 211 to rotate. The other end of the inner wall of the support frame 201 is rotatably connected to a driven shaft 213 through a bearing. The outer surfaces of the driving shaft 211 and the driven shaft 213 are transmission-connected to the inner wall of the feeding belt 212. The driving shaft 211 rotates and drives the feeding belt 212 to rotate, and the other end of the feeding belt 212 drives the driven shaft 213 to rotate, thereby further realizing the conveying and unloading process of the waste glass above the feeding belt 212.

[0047] The color inspection component 3 includes a central plate 301, and splicing plates 302 are symmetrically provided on both sides of the central plate 301. The bottom of the splicing plate 302 is fixedly connected to the top of the support frame 201. The splicing plate 302 is provided to improve the stability and support of the position of the central plate 301. A plurality of bottom grooves 304 are evenly provided at the bottom of the central plate 301 and on one side close to the unloading frame 101. Two arc surfaces 314 are symmetrically provided on both sides below the bottom groove 304. The setting of the arc surface 314 improves the stability and limiting property of the swing of the internal trapezoidal swing rod 308, thereby preventing the trapezoidal swing rod 308 from swinging too much and being clamped with the bottom of the bottom groove 304 to reduce safety.

[0048] An electric push rod 305 is provided at the inner top of the bottom groove 304, and a trapezoidal swing rod 308 is movably connected to the bottom output end of the electric push rod 305, so that the trapezoidal swing rod 308 can move up and down and swing under the electric push rod 305. A cross plate 306 is provided at the bottom output end of the electric push rod 305, and the bottom of the cross plate 306 is rotatably connected to the top of the trapezoidal swing rod 308 through a torsion spring seat 307. When the electric push rod 305 starts to extend, the trapezoidal swing rod 308 at the bottom is driven to move up and down through the cross plate 306 and the torsion spring seat 307, and when the trapezoidal swing rod 308 swings, the torsion spring seat 307 is twisted synchronously and exerted on it. Torsion, the trapezoidal swing rod 308 is tilted near the color sorter 303, and the width of the trapezoidal swing rod 308 gradually increases from top to bottom. A rubber baffle 309 is provided at the bottom of the trapezoidal swing rod 308. The rubber baffle 309 is elastic. When the trapezoidal swing rod 308 moves up and down, it drives the rubber baffle 309 to move up and down. The height of the trapezoidal swing rod 308 inside the bottom groove 304 changes, and the corresponding width of the trapezoidal swing rod 308 also changes. At the same time, the rubber baffle 309 is used to correct the position of the waste glass above the feeding belt 212, so as to further improve the efficiency and effect of subsequent color inspection and zoning of the waste glass.

[0049] The side wall of the trapezoidal swing rod 308 is provided with an angle sensor 310, and the angle sensor 310 is used to detect the swing angle value of the trapezoidal swing rod 308. Two side walls of the bottom groove 304 are symmetrically provided with two transverse grooves 311, and the interior of the transverse groove 311 is sealed and slidably connected with a sliding block rod 313, and the sliding block rod 313 slides in a sealed manner inside the transverse groove 311, and the ends of the sliding block rods 313 that are close to each other are in contact with the side walls of the trapezoidal swing rod 308. When the trapezoidal swing rod 308 swings inside the bottom groove 304, the trapezoidal swing rod 308 squeezes the sliding block rod 313 and drives the sliding block rod 313 to move left and right inside the transverse groove 311. The side wall of the transverse groove 311 is provided with a connecting spring 312, and the other end of the connecting spring 312 is fixedly connected to the side wall of the sliding block rod 313. The setting of the connecting spring 312 further improves the elastic reset performance of the sliding block rod 313 inside the transverse groove 311.

[0050] An exhaust hole 315 is provided at the bottom of the transverse groove 311, and the bottom of the sliding baffle 313 matches the top of the exhaust hole 315. When the sliding baffle 313 is squeezed by the trapezoidal swing rod 308 and corresponds to the squeezing of the connecting spring 312 and moves toward the inner wall end of the transverse groove 311, the blocking area of ​​the exhaust hole 315 by the sliding baffle 313 increases, and the wind force discharged along the exhaust hole 315 decreases. The other end of the exhaust hole 315 passes through the center plate 301 and is located at the end of the arc surface 314. The arc surface 314 matches the side wall of the trapezoidal swing rod 308. When the swing amplitude of the trapezoidal swing rod 308 further increases and reaches the end of the arc surface 314, the trapezoidal swing rod 308 blocks the output end of the exhaust hole 315, so that the exhaust hole 315 on this side no longer discharges wind.

[0051] A plurality of color sorters 303 are arranged in a uniform array at the bottom of the center plate 301 and on one side away from the material unloading frame 101. The color sorters 303 are used to sort the waste glass above the feeding belt 212. A plurality of clean air pumps 316 are arranged in a uniform array at the top of the center plate 301. A plurality of vertical holes 317 are arranged in a uniform array at the top of the center plate 301. The bottom output end of the clean air pump 316 is connected to the top of the vertical hole 317. The clean air pump 316 is started and the clean gas is passed into the vertical hole 317 along the output end. , both sides of the vertical hole 317 are connected with connecting holes 318, the bottoms of the connecting holes 318 are connected with the transverse grooves 311, and the bottoms of the connecting holes 318 correspond to the tops of the exhaust holes 315, so the gas inside the vertical hole 317 reaches the inside of the connecting holes 318 to both sides, and further passes downward through the transverse grooves 311 to be discharged from the exhaust holes 315, and when the sliding blocking rod 313 moves laterally inside the transverse grooves 311 and blocks the connecting holes 318 and the exhaust holes 315, the wind force discharged along the exhaust holes 315 is correspondingly reduced.

[0052] The partition component 4 includes a limit frame 401, an inner groove 402 is provided inside the limit frame 401, and a plurality of nozzles 408 are uniformly arranged inside the inner groove 402. The nozzles 408 work and separate and sort the color-sorted waste glass. A fixed plate 403 is provided on the inner wall of the inner groove 402. The position of the fixed plate 403 does not change. The lower side of the fixed plate 403 close to the support frame 201 is fixedly connected to the side wall of the nozzle 408. The fixed plate 403 supports and fixes the position of the nozzle 408. An output hole 405 is provided on the upper part of the fixed plate 403. A partition air pump 404 is provided on the top of the fixed plate 403. The bottom output end of the air pump 404 is connected to the top of the output hole 405. The partition air pump 404 is started and the partition gas is passed into the output hole 405 along the bottom output end. The bottom of the output hole 405 is connected with a central hole 406. One side of the central hole 406 is evenly connected with multiple inclined holes 407. The other end of the inclined hole 407 is connected to the nozzle 408. The interior of the inclined hole 407 is provided with an electromagnetic flow valve 409. When the electromagnetic flow valve 409 is opened, the gas inside the output hole 405 reaches the interior of the nozzle 408 along the central hole 406 and the inclined hole 407 and is ejected, thereby realizing the partitioning and sorting of the sorted waste glass.

[0053] An air box 412 is provided on one side of the limit frame 401, and partition gas is carried inside the air box 412. A ventilation hose 410 is provided at the top output end of the air box 412. A side hole 411 is provided inside the limit frame 401. The other end of the ventilation hose 410 passes through the side hole 411 and is connected to the input end of the partition air pump 404. The partition air pump 404 is started and the gas inside the air box 412 is extracted with the help of the ventilation hose 410. An impurity box 413 is provided at the bottom of the inner tank 402 and close to the side of the support frame 201. A finished product box 414 is provided on the side of the impurity box 413 away from the support frame 201. The finished product box 414 is located at the inner bottom of the inner tank 402. After the color sorter 303 has color-sorted the waste glass above the feeding belt 212, the nozzle 408 sprays gas and blows impurities into the impurity box 413, and the recycled glass falls into the finished product box 414 under the inertia of the feeding belt 212 for recycling.

[0054] When the waste glass is above the feeding belt 212 and is conveyed backward, if the waste glass is too large and is between the two color sorters 303, and the color sorting data of the two color sorters 303 for the same piece of waste glass are different, it is easy to cause the subsequent sorting accuracy of the waste glass to decrease. When the size of the waste glass changes, if the amount of gas sprayed by the nozzle 408 remains unchanged, the efficiency of the nozzle 408 in separating the waste glass by reverse blowing is reduced, thereby making it impossible to reasonably zon the waste glass for recycling; and when the waste glass is overlapped above the feeding belt 212, When stacking, the stacked waste glass cannot be removed by the elastic force of the rubber stopper 309 itself, and the color sorting accuracy of the stacked waste glass by the color sorter 303 is reduced, so the subsequent wind zoning and sorting of the waste glass is more difficult; at the same time, if there are impurities attached to the outer surface of the waste glass, the existing technology lacks the effect of scraping and cleaning the impurities, and when the impurities adhere to the outer surface of the feeding belt 212 and are continuously conveyed with the feeding belt 212, the impurities will not only pollute the waste glass, but also affect the color sorting accuracy of the waste glass by the color sorter 303.

[0055] In actual use, this embodiment is Figure 3 Distinguishing between left and right directions, the broken waste glass is poured into the collecting bucket 102, and falls onto the pouring frame 101 along the bottom hole 103 at the bottom of the collecting bucket 102, the vibration motor 105 is started and drives the pouring frame 101 to vibrate through the support plate 104, and cooperates with the elastic support of the elastic bottom plate 106 to achieve the stability and support of the up and down vibration of the pouring frame 101, and the waste glass above the pouring frame 101 is continuously and evenly poured down onto the feeding belt 212, so as to avoid stacking or contact of the waste glass, etc., which reduces the accuracy of subsequent color sorting and wind zoning and sorting.

[0056] At the same time, the driving motor 206 starts and drives the transmission shaft 207 to rotate, the transmission shaft 207 drives the driving wheel 208 to rotate, the driving wheel 208 drives the conveyor belt 209 to rotate, the conveyor belt 209 drives the driven wheel 210 to rotate, the driven wheel 210 drives the driving shaft 211 to rotate, the driving shaft 211 cooperates with the driven shaft 213 to drive the feeding belt 212 to rotate, thereby realizing the backward transmission of the waste glass above the feeding belt 212.

[0057] When the waste glass reaches the bottom of the central plate 301 above the feeding belt 212, the waste glass is first cleaned and corrected by the elastic contact force of the rubber stopper 309, and the cleaning air pump 316 is started to discharge the gas into the vertical hole 317. The gas in the vertical hole 317 goes down along the connecting hole 318 to the end of the horizontal groove 311, and finally goes down to the exhaust hole 315 and is discharged. The wind force cleans the surface of the waste glass and the top of the feeding belt 212, further improving the accuracy of subsequent color sorting of the waste glass. Under the thrust of the waste glass, the rubber stopper 309 drives the trapezoidal swinging rod 308 to stretch the torsion spring seat 307 to rotate toward the end of the color sorter 303. The angle value detected by the angle sensor 310 increases, and the trapezoidal swinging rod 308 squeezes the torsion spring seat 307. The sliding baffle rod 313 on the right side is pressed, and the sliding baffle rod 313 on the right side squeezes the connecting spring 312 and moves to the right side along the transverse groove 311, so that the blocking area of ​​the exhaust hole 315 on the right side by the sliding baffle rod 313 increases, and the sliding baffle rod 313 on the left side moves to the right side under the elastic force of the connecting spring 312, and the blocking area of ​​the exhaust hole 315 on the left side by the sliding baffle rod 313 decreases, so that the exhaust volume of the exhaust hole 315 on the left side increases, and the exhaust volume of the exhaust hole 315 on the right side decreases, thereby cooperating with the rubber baffle rod 309 to improve the scraping and cleaning effect of impurities on the outer surface of the waste glass, and at the same time, the pulse change of the wind force inside the exhaust hole 315 can further improve the wind cleaning effect of impurities inside the exhaust hole 315 and the outer surface of the feeding belt 212, with stronger adaptability and higher stability.

[0058] After that, the waste glass reaches the bottom of the color sorter 303, and multiple color sorters 303 are started and cooperate with the camera system carried by themselves to color sort the waste glass. When the color of the waste glass does not meet the requirements, the color sorter 303 provides a corresponding signal. Then, when the waste glass reaches the end of the limit frame 401 after color sorting, the control panel 203 controls the partition air pump 404 to start and apply suction force. The gas inside the air box 412 is discharged to the output hole 405 along the ventilation hose 410, and reaches the inside of each inclined hole 407 along the output hole 405 and the center hole 406. When the waste glass that meets the color requirements reaches the end of the feeding belt 212, the control panel 203 controls the electromagnetic flow valve 409 to be closed. When the waste glass that does not meet the color requirements flies out along the end of the feeding belt 212, the control panel 203 controls the electromagnetic flow valve 409 at the corresponding position to start and open, and the gas inside the inclined hole 407 is directly ejected along the nozzle 408. The gas ejected from the nozzle 408 exerts a wind force on the waste glass, thereby pushing the waste glass to fly obliquely to the impurity box 413 for recycling, thereby further realizing the color sorting and zoning of the waste glass, with higher sorting efficiency and better sorting effect.

[0059] At the same time, when the waste glass comes into elastic contact with the rubber baffle 309 under the conveying action of the feeding belt 212, the rubber baffle 309 drives the trapezoidal swinging rod 308 to synchronously stretch the torsion spring seat 307 to rotate, and the angle value detected by the angle sensor 310 increases. When the trapezoidal swinging rod 308 rotates to a certain angle, that is, the angle value detected by the angle sensor 310 reaches the preset angle value, the waste glass passes under the rubber baffle 309. At the same time, when the volume of the waste glass is larger, the waste glass drives the rubber baffle 309 to be in an inclined state for a longer time, and the corresponding angle value detected by the angle sensor 310 is in the preset angle value for a longer time. In order to ensure that the nozzle 408 reaches the end of the feeding belt 212 for the waste glass that does not meet the color requirements, the control panel 203 controls the electromagnetic flow valve 409 at the corresponding position to open more, and the amount of gas sprayed along the nozzle 408 increases, and the force exerted by the gas sprayed from the nozzle 408 on the waste glass that does not meet the color requirements increases and causes it to fly back to the impurity box 413 for recycling.

[0060] And when the time for the angle value detected by the angle sensor 310 to reach the set angle preset value is greater than the set preset time, it means that the volume of the waste glass is too large. When the waste glass that meets the color requirements is conveyed to the end of the feeding belt 212, since the waste glass that meets the color requirements will fall off the finished product box 414 when it falls under its own weight, the control panel 203 controls the electromagnetic flow valve 409 at the corresponding position to open a certain size, and a small amount of gas in the inclined hole 407 is ejected along the nozzle 408, thereby applying a reverse thrust to the waste glass that meets the color requirements, further ensuring that the waste glass that meets the color requirements can stably fall into the finished product box 414 for recycling and processing, and avoiding its separation and damage due to excessive weight.

[0061] If the size of the waste glass is too large, and when it reaches the bottom of the central plate 301 under the conveying action of the feeding belt 212, the waste glass belt exerts an action on the adjacent multiple rubber baffles 309 and drives the trapezoidal swing rod 308 to stretch the torsion spring seat 307 to rotate, then the angle values ​​detected by the multiple adjacent angle sensors 310 increase and reach the preset angle value. In this case, it means that the waste glass is a whole piece, and it needs to be color-sorted and sorted as a whole later. When the waste glass breaks away from the rubber baffle 309 and reaches the bottom of the multiple color sorters 303, the corresponding multiple color sorters 303 color sort the waste glass. If each color sorter 303 detects that the waste glass meets the color requirements, the color of the large-sized waste glass meets the requirements. When it reaches the end of the feeding belt 212 later, the control panel 203 controls the multiple electromagnetic flow valves 409 at the corresponding positions to start the smaller size, and the multiple adjacent nozzles 408 are started at the same time and spray part of the gas, so that the waste glass can accurately fall into the finished product box 414 for recycling.

[0062] At the same time, when one of the color sorters 303 at the multiple corresponding positions detects that the color does not meet the requirements, while the other color sorters 303 detect that the color meets the requirements, it means that the color of the large-sized waste glass does not meet the requirements. As the feeding belt 212 drives the large-sized waste glass to the end of the feeding belt 212, the control panel 203 controls the multiple electromagnetic flow valves 409 at the corresponding positions to open a larger size. The gas sprayed from the nozzle 408 exerts a force on the large-sized waste glass and makes it fly back to the impurity box 413 for recycling, thereby further improving the sorting precision and accuracy of waste glass of different sizes, with stronger adaptability and higher stability.

[0063] When the waste glass is in a stacked state, the waste glass reaches the bottom of the central plate 301 under the conveying action of the feeding belt 212 and contacts with the rubber stopper 309 and drives the trapezoidal swing rod 308 to twist the torsion spring seat 307 to rotate. At the same time, due to the stacking of the waste glass, the waste glass drives the trapezoidal swing rod 308 to increase its rotation angle through the rubber stopper 309, and the angle value detected by the angle sensor 310 is greater than the preset angle value. If the stacked waste glass is allowed to be conveyed backward, it will affect the color sorting of the subsequent color sorter 303. The control panel 203 controls the electric push rod 305 to start and drives the trapezoidal swing rod 308 to move downward through the cross plate 306 and the torsion spring seat 307. The trapezoidal swing rod 308 drives the rubber stopper 309 to move downward, and the force exerted by the rubber stopper 309 on the waste glass located above increases. In addition, since the width of the trapezoidal swing rod 308 close to the color sorter 303 gradually increases from top to bottom, even if the trapezoidal swing rod 308 tilts to the right, the extrusion force exerted by the trapezoidal swing rod 308 on the sliding stopper 313 on the right is reduced, and the trapezoidal swing rod 308 is The squeezing force applied by the rod 308 to the sliding baffle rod 313 on the left side remains unchanged, and the connecting spring 312 on the right side drives the sliding baffle rod 313 to move to the left side under the action of the elastic force, and the blocking area of ​​the exhaust hole 315 by the sliding baffle rod 313 on the right side is reduced, while the blocking area of ​​the exhaust hole 315 by the sliding baffle rod 313 on the left side remains unchanged, and the amount of gas discharged from the connecting hole 318 along the right exhaust hole 315 increases, and the corresponding right side gas applies a thrust to the right side of the rubber baffle rod 309, and cooperates with the torsion spring seat 307 to push the trapezoidal swing rod 308 and the rubber baffle rod 309 themselves The elastic force exerts a reverse force on the waste glass stacked on top, thereby ensuring that the stacked waste glass slides down, and the force exerted by the waste glass on the rubber stopper 309 is reduced to the initial value, and the angle value detected by the angle sensor 310 is restored to the preset angle value, then the control panel 203 controls the electric push rod 305 to start in the reverse direction and drives the trapezoidal swing rod 308 to move upward and return to its original position through the cross plate 306 and the torsion spring seat 307, thereby preventing the waste glass from stacking and reducing the color sorting effect of the subsequent color sorter 303, thereby ensuring the normal and stable operation of the sorting device.

[0064] At the same time, when the waste glass is continuously cleaned, some impurities will adhere to the outer surface of the feeding belt 212, and the impurities will affect the normal color sorting of the waste glass, that is, when the impurities reach the color sorter 303 and are detected, the impurities are transported by the feeding belt 212 and arrive under the center plate 301 again, and the control panel 203 controls the electric push rod 305 at the corresponding position to start and extend downward to the maximum value, and the electric push rod 305 drives the trapezoidal swing rod 308 to move downward to the maximum distance through the cross plate 306 and the torsion spring seat 307, and the bottom of the trapezoidal swing rod 308 contacts the top of the feeding belt 212, and as the feeding belt 212 continues to rotate, the trapezoidal swing rod 308 applies a scraping force to the impurities, thereby improving the cleaning effect of the impurities.

[0065] The air in the connecting hole 318 cannot be discharged along the right exhaust hole 315, while the left exhaust hole 315 is still in an open state. At this time, as the trapezoidal swing arm 308 rotates, the thrust of the sliding baffle 313 on the left side is reduced. Under the elastic force of the connecting spring 312, the sliding baffle 313 is driven to move to the right side, and the blocking area of ​​the exhaust hole 315 by the sliding baffle 313 is reduced. The amount of gas discharged from the connecting hole 318 along the left exhaust hole 315 is increased, and the rubber baffle 309 is used to scrape off the impurities adhering to the top of the feeding belt 212, thereby further improving the cleaning effect of the impurities, so that the impurities can be separated from the feeding belt 212 and avoid affecting the subsequent color sorting and categorizing of the waste glass.

[0066] As the impurities are cleaned, the control panel 203 controls the electric push rod 305 to move upward in the reverse direction to return to its original position, and the bottom of the trapezoidal swing rod 308 is separated from the feeding belt 212, and the device resumes normal working state and repeats the above process to color sort and classify the subsequent waste glass.

[0067] The device has high sorting accuracy, high sorting efficiency and good sorting effect, which can meet the sorting requirements of different waste glasses, and is simple to operate, highly controllable and adjustable, stable and efficient, and highly adaptable, which can meet the requirements of different working states and is suitable for mass production. The device can also adjust the position of waste glasses of different sizes, and adjust the amount of gas ejected by the nozzle 408 in accordance with the color sorting result of the color sorter 303, so as to ensure that all waste glasses can reach the appropriate area for recycling and treatment. When the waste glasses are in a stacked state, a reverse thrust is applied to the waste glasses located above by means of the height change of the trapezoidal swing rod 308, so as to ensure that the stacked waste glasses are separated from each other, and the subsequent color sorting and zoning sorting effect is effectively improved. At the same time, when some impurities are adhered to the outer surface of the feeding belt 212, the trapezoidal swing rod 308 moves further downward and contacts with the outer surface of the feeding belt 212 by mutual compression, and cooperates with the increase of the amount of gas discharged from the left exhaust hole 315, so as to effectively improve the cleaning effect of the adhered impurities, and effectively avoid affecting the subsequent color sorting and zoning sorting of waste glasses.

[0068] The sorting method of the waste glass sorting device as described above comprises the following steps:

[0069] S1. When the waste glass reaches the bottom of the central plate 301, the waste glass contacts the rubber stopper 309 and drives the trapezoidal swing arm 308 to twist the torsion spring seat 307 to rotate. The angle value detected by the angle sensor 310 increases to the preset angle value. When the time for the angle value detected by the angle sensor 310 to reach the preset angle value increases, the opening area of ​​the electromagnetic flow valve 409 increases, and the amount of gas sprayed from the nozzle 408 increases.

[0070] S2. When the angle values ​​detected by the adjacent multiple angle sensors 310 change at the same time, the multiple color sorters 303 at the corresponding positions simultaneously sort the same waste glass, and the multiple nozzles 408 at the corresponding positions simultaneously spray gas.

[0071] S3. When the angle value detected by the angle sensor 310 is greater than the preset angle value, the electric push rod 305 starts to extend and drives the trapezoidal swing rod 308 below to move downward, the extrusion force applied by the trapezoidal swing rod 308 to the right sliding baffle 313 is reduced, the blocking area of ​​the right exhaust hole 315 by the right sliding baffle 313 is reduced, the air volume discharged from the right exhaust hole 315 is increased and cooperates with the rubber baffle 309 to push the stacked waste glass in the opposite direction.

[0072] S4. When impurities are adhered to the outer surface of the feeding belt 212 and the impurities reach the bottom of the center plate 301, the electric push rod 305 starts to extend and drives the trapezoidal swing rod 308 to move downward to the maximum distance. The bottom of the trapezoidal swing rod 308 and the top of the feeding belt 212 are squeezed and contacted with each other. The trapezoidal swing rod 308 swings to the right to the maximum angle and blocks the exhaust hole 315 on the right. The air volume inside the exhaust hole 315 on the left increases and cooperates with the rubber baffle rod 309 to scrape and blow away the impurities.

[0073] By further limiting the sorting method, the sorting efficiency can be improved and the sorting quality can be guaranteed.
