[0044] In ore sorting, various material placement schemes are often employed. In some related technologies, the diverse testing and evaluation of ore sorting machines typically utilizes fixed-viewpoint or single-dimensional monitoring methods. This makes it difficult to comprehensively capture the multidimensional attitude changes of materials under different throwing patterns and speeds (such as flipping, tilting, and spatial distribution during the falling process). Furthermore, it is susceptible to external light interference, leading to blurred material characteristics, unclear dynamic attitude recording, and limited data quality. Simultaneously, the fixed structure of the light source and imaging equipment lacks sufficient adjustment capabilities, making it difficult to quickly adapt to different throwing trajectories. This results in poor testing flexibility and versatility, requiring frequent hardware adjustments or structural reconstruction, leading to low efficiency and high costs, and failing to provide a comprehensive and scientific evaluation basis for commercial sorting standards.

[0045] To overcome the problems existing in related technologies, an exemplary embodiment of this disclosure provides a material throwing test apparatus 100, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the device is used to acquire the posture of the thrown material. The throwing test device 100 may include: a test bracket 110, a light source assembly 120, and a camera assembly 130.

[0046] Test bracket 110, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, it can be made of high-strength materials, such as aluminum or steel. The test bracket 110 can include multiple horizontal and vertical beams, and can mount the light source assembly 120 and the camera assembly 130. The multiple horizontal and vertical beams can be moved in position via sliding tracks, allowing the test bracket 110 to quickly adjust its structural layout to adapt to different material throwing test scenarios. When the light source assembly 120 needs to change its illumination angle or the camera assembly 130 needs to adjust its shooting position, the horizontal or vertical beams can be adjusted to precisely align with different monitoring areas of the material throwing trajectory, ensuring comprehensive capture of material posture changes.

[0047] Light source assembly 120, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 24As shown, the light source assembly 120 can be movably mounted on the test bracket 110 and can be used to support the light source 121 and provide illumination to the thrown material. The light source assembly 120 may include the light source 121 and the light source connector 122. The light source 121 can be fixed to the test bracket 110 via the light source connector 122, and the fixing method can be bolt connection, snap connection, etc. The light source 121 can be set on the test bracket 110, and the height or left and right relationship between it and the material can be adjusted by using the slide on the test bracket 110. At this time, the adjustment can be coarse. After the light source 121 is set on the light source connector 122, it can be movable and adjusted. The position and angle of the light source 121 in the light source assembly 120 can be adjusted through the light source connector 122 to adapt to different angles and positions of the material. At this time, the adjustment can be fine. There can be one or more light source assemblies 120, and the number of light source assemblies 120 can be set according to the number of camera assemblies 130. The light source assembly 120 can be set between the thrown material and the camera assembly 130 to facilitate providing illumination to the thrown material and allowing the camera assembly 130 to accurately capture the posture of the material.

[0048] Camera component 130, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, the camera assembly 130 can be movably mounted on the test bracket 110 to support the camera 131 and capture the posture of the thrown material. The camera assembly 130 is correspondingly positioned with the light source assembly 120 so that the camera 131 captures the material illuminated by the light source 121. The camera assembly 130 may include a camera 131 and a camera connector 132. The camera 131 can be fixed to the test bracket 110 via the camera connector 132, and the fixing connection can be a bolt connection, a snap-fit ​​connection, etc. The camera 131, fixed to the test bracket 110, can be adjusted for height and left / right position via the slide rails of the test bracket 110; this adjustment is a coarse adjustment. After the camera 131 is positioned on the camera connector 132, it can be adjusted according to the angle or position of the material; this adjustment is a fine adjustment. The camera 131 in the camera assembly 130 can capture the posture of the thrown material. There can be one or more camera assemblies 130. One camera assembly 130 can be positioned on the same horizontal plane as the thrown material to capture its posture. Two camera components 130 can be positioned on different horizontal planes. The first camera component 130 can be positioned on the same horizontal plane as the material being ejected, while the second camera component 130 can be positioned below the first camera component 130 to capture the posture of the material in the next stage, specifically the posture of the material during ejection. Corresponding light source components 120 can be configured to provide illumination for the corresponding material. The two camera components 130 can transmit the captured information to software for data comparison and analysis. This allows for comparison of different posture changes of the material and whether the material is evenly distributed, providing a basis for verifying subsequent solutions. Since most materials are irregular, different scanning angles will result in different projected areas, leading to variations in camera time. By examining the adhesion and obstruction of materials distributed at the same camera position, combined with the material drop speed, the optimal material yield can be calculated. By examining the difference in scanning time for the same material at different camera positions, it can be determined whether the material's posture changes as it passes through the two camera positions. Camera 131 can also be replaced with an X-ray machine to scan the material's posture.

[0049] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 24 As shown, the camera assembly 130 can capture and record the trajectory of the material not only from the front but also from the side. When the camera assembly 130 is positioned on the front of the material, it can focus on comparing the posture of the same batch of material at different positions; in this case, a line scan camera can be used. When the camera assembly 130 is positioned on the side of the material, it can focus on recording the process changes in the trajectory of a single material; in this case, a surface scan camera can be used.

[0050] In this embodiment, the material throwing test device 100 is equipped with a camera assembly 130 and a light source assembly 120. This allows the camera assembly 130 to clearly record the posture changes of the material at different stages during the throwing process in different forms. This provides a high-quality data foundation for subsequent image analysis of the material's posture stability and provides a basis for determining whether the material spreading process meets sorting requirements. Furthermore, the camera assembly 130 and the light source assembly 120 can be flexibly installed. The illumination angle of the light source 121 and the shooting angle of the camera 131 can be flexibly adjusted according to different throwing forms and different movement trajectories of the material. This ensures that the camera 131 can capture the posture of the material, meeting the testing requirements of diverse material spreading schemes and improving the versatility of the material throwing test device 100.

[0051] In some embodiments, such as Figure 6 , Figure 7 , Figure 8 , Figure 9 As shown, the light source assembly 120 may include: a horizontal plate 123, a vertical plate 124, a light source connector 122, a handle 125, a rotating shaft 126, a first fixing bolt 127, and a light source 121.

[0052] like Figure 6 , Figure 7 , Figure 8 , Figure 9 As shown, a horizontal plate 123 can be fixed to the test bracket 110; a vertical plate 124 can be connected to the horizontal plate 123 and extends downward, and the vertical plate 124 can be provided with a first circular hole and a circumferential strip hole; a light source connector 122 can be fixedly connected to the vertical plate 124, and the light source connector 122 can be provided with two second circular holes for fixing the light source 121. The horizontal plate 123 can be made of high-strength aluminum alloy sheet and can be fixedly connected to the test bracket 110 by bolts or clips. The vertical plate 124 can be integrally formed with the horizontal plate 123 or welded, and is set perpendicular to the horizontal plate 123 and extends downward, and the surface of the vertical plate 124 can be provided with a first circular hole and a circumferential strip hole. Two light source connectors 122 can be provided, respectively fixed to both sides of the light source 121. They can be in the form of a rectangular groove structure. The bottom end of the rectangular groove can be fixedly connected to the light source 121, such as by bolts, and the side end of the rectangular groove can be fixedly connected to the vertical plate 1224, such as by bolts, thereby fixing the light source 121 to the vertical plate 124. Two second circular holes can be formed on the side end of the light source connector 122 for bolt fixing to the vertical plate 124.

[0053] Handle 125, such as Figure 6 , Figure 7 , Figure 8 , Figure 9As shown, the light source connector 122 can be a rectangular strip-shaped piece, which can be fixedly connected to the vertical plate 124. The handle 125 can be provided with two third circular holes. The rotating shaft 126 can pass through the first circular hole, one of the second circular holes, and one of the third circular holes. The first fixing bolt 127 can pass through the circumferential holes, one of the second circular holes, and one of the third circular holes. The light source connector 122 can be fixed to multiple positions on the vertical plate 124 by the first fixing bolt 127. A light source 121 can be mounted on the light source connector 122 to provide illumination to materials. The handle 125 can be a rectangular strip-shaped metal piece with two third circular holes on its surface. It can be used as an operating handle or for angle positioning. The rotation angle of the handle 125 can be ±20 degrees. The rotating shaft 126 can be a high-precision stainless steel shaft, which can pass through the first circular hole, one of the second circular holes, and one of the third circular holes to form a rotation fulcrum, allowing the light source connector 122 to rotate around the rotating shaft 126. The first fixing bolt 127 can pass through the circumferential slot, another second circular hole, and the third circular hole. Tightening the nut allows for multi-angle positioning and fixation of the light source connector 122. The light source connector 122 can be rotatably connected to the vertical plate 124 via the rotating shaft 126. Simultaneously, the first fixing bolt 127 slides within the circumferential slot, allowing for angle and position adjustment. The handle 125, the vertical plate 124, and the light source connector 122 are linked via the rotating shaft 126 and the fixing bolt. The handle 125 can push the light source connector 122 to rotate. After adjusting to a suitable angle, the retaining spring can fix the rotating shaft, and tightening the bolt locks it in place, thus achieving angle adjustment of the light source 121.

[0054] In this embodiment, by setting up a light source 121 and other connecting components, the light source 121 can be fixed on the test bracket 110. Through the circumferential adjustment and cooperation of other circular holes in the connecting components, the handle 125 can rotate the light source connector 122 to adjust the position and angle of the light source 121. The adjustment is simple and can provide a reliable lighting control scheme for the attitude test of the material distribution scheme of the mining sorting machine. It can also enable the camera component 130 to clearly record the attitude changes of the material at different stages during the different forms of material throwing. This can provide a high-quality data foundation for subsequent image analysis of the material attitude stability and provide a basis for subsequent judgment on whether the material distribution process meets the sorting requirements.

[0055] In some embodiments, such as Figure 10 , Figure 11 As shown, the camera assembly 130 may include: a bracket connecting plate 133, a camera connector 132, at least three screws 134, and a camera 131.

[0056] Bracket connecting plate 133, such as Figure 10 , Figure 11As shown, it can be fixed to the test bracket 110. The bracket connecting plate 133 can be a high-strength aluminum alloy plate. The camera connector 132 can be fixedly connected to the bracket connecting plate 133 at its bottom, and at least three nuts can be fixedly provided on its side wall. At least three screws 134 can be provided corresponding to the nuts and can be used to fix the camera 131. The camera 131 can be installed on the camera connector 132 and can be used to photograph the posture of the material. The bracket connecting plate 133 can be an L-shaped plate structure. The bottom plate of the bracket connecting plate 133 can be provided with multiple mounting holes, which can be strip holes, to fix the camera 131 to the test bracket 110, which can be done by bolt connection, snap connection, etc. The side plate of the bracket connecting plate 133 can be provided with round holes for placing the camera 131. The camera connector 132 can be a vertical rectangular groove structure. The lower part of the camera connector 132 can be fixedly connected to the bracket connecting plate 133, which can be fixed by bolts. Multiple nuts, at least three, can be fixedly installed on the side wall of the camera connector 132. The three nuts can be directly welded to the camera connector 132, or directly fixed to the bracket connecting plate 133 by three adjusting screws 134. Through three-point positioning, the position of the camera 131 can be calibrated and fine-tuned. The camera 131 can be fixed to the camera connector 132, and the camera 131 can capture the posture and state of the material.

[0057] In this embodiment, the camera 131 can be fixed to the camera connector 132 by setting at least three adjusting screws 134. The position of the camera 131 can be calibrated and fine-tuned by the three adjusting screws 134. The position and angle of the camera 131 can be precisely adjusted. This allows the camera 131 to clearly record the posture changes of materials at different stages during different forms of material throwing. This provides a high-quality data foundation for subsequent image analysis of material posture stability and provides a basis for subsequent judgment on whether the material spreading process meets the sorting requirements.

[0058] In some embodiments, such as Figure 24 As shown, the material throwing test device 100 may further include: a side camera mounting bracket and a side camera 150.

[0059] The side camera mounting bracket can be movably mounted on the test bracket 110 and extends to the side. The side camera mounting bracket, relative to the test bracket 110, can be positioned beside the material being thrown. The side camera mounting bracket can be directly positioned to the side of the material, or the test bracket 110 can be extended to the side of the material. The side camera mounting bracket can be equipped with multiple horizontal and vertical beams, which are movable and can be moved via slide rails, thereby adjusting the height and left-right position of the side camera 150.

[0060] Side camera 150, such as Figure 10 , Figure 11As shown, it can be mounted on a side camera mounting bracket to capture the posture of the material from the side when it is thrown. The side camera 150 can be a surface scan camera, which can focus on the process changes of the trajectory of a single material. The square camera 131 can focus on capturing the posture comparison of the same batch of materials at two or more positions, and can be a line scan camera. The side camera 150 can be fixed on the side camera mounting bracket to capture the motion state of the material. The side camera 150 can be equipped with a corresponding light source assembly 140 to provide illumination for the thrown material. The side camera 150 can be equipped with a corresponding side camera connector to adjust the position and angle of the side camera 150.

[0061] In this embodiment, by setting a side camera mounting bracket 140 and a side camera 150 beside the material, the side posture of the material can be captured, and the process changes of the movement trajectory of a single material can be recorded. This achieves accurate monitoring of the side posture of the material and solves the problem of information loss in traditional single-view shooting. It has significant advantages in terms of flexibility, stability, and testing efficiency, and provides key technical support for the scientific evaluation of material placement schemes for mining sorting machines.

[0062] In some embodiments, the material throwing test apparatus 100 may further include: a material receiving device 160, such as... Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 12 , Figure 13 As shown, the receiving device 160, positioned below the test bracket 110, can be used to receive the thrown material. The receiving device 160 can be open to allow material to fall smoothly into it. The shape of the container can be designed according to actual needs, such as square or round. For ease of handling and operation, the receiving device 160 can be equipped with a handle or similar structure. The receiving device 160 effectively receives the thrown material, ensuring that the material does not scatter, thus improving the safety of the testing process and the material recovery rate.

[0063] In this embodiment of the disclosure, by setting up a receiving device 160, the thrown material can be received in the receiving device 160, which can effectively receive the thrown material, ensure that the material does not scatter, and improve the safety of the testing process and the material recovery rate.

[0064] In some embodiments, such as Figure 12 , Figure 13 As shown, the receiving device 160 may include: a hopper 161, a bottom support 162, and multiple ground wheels 163.

[0065] Hopper 161, such as Figure 12 , Figure 13As shown, the front plate of the hopper 161 can be inclined to receive the thrown material; the bottom support 162 can be flat and can be set at the bottom of the hopper 161; and multiple wheels 163 can be set at the bottom of the bottom support 162. The hopper 161 can adopt an inclined front plate design to effectively guide the thrown material to slide smoothly into the hopper. The hopper as a whole is semi-enclosed and open, and can be made of high-strength metal sheet bent and welded. The sides and rear plates can be set vertically to provide a confinement space for the material. The inclined extension of the front plate forms a guiding slope. This structure increases the material receiving range and guides the material to the rear. The bottom support 162 can be a flat structure and can be made of steel plate of appropriate thickness, with good load-bearing capacity. The size of the bottom support 162 can be adapted to the bottom of the hopper 161, ensuring stable support of the hopper while providing a flat base plane for the installation of the wheels 163. The number of ground wheels 163 can be no less than three or four, and they can be evenly distributed at the bottom of the base support 162. The hopper 161 is fixed to the upper surface of the base support 162 by welding or bolting to ensure that the two are firmly connected and that there is no relative displacement when receiving materials.

[0066] In this embodiment, the material receiving device 160 comprises a hopper 161, a base support 162, and wheels 163. The hopper 161, as the main material receiving component, effectively receives various types of thrown materials due to its open opening and inclined front plate design, completing the initial material collection. The wheels 163 allow the material receiving device 160 to move, enabling operators to easily move the device to a designated location according to testing needs. This allows for quick adjustments within the testing site and transfers between different testing areas. The base support 162 provides stable support for the hopper 161, ensuring its balance during material reception. Even when receiving heavy or impact-prone materials, the device remains stable and does not tilt or tip over. The material receiving device 160 efficiently and stably completes the material receiving task. The inclined front plate design significantly improves the material collection success rate, reducing cleanup work and material loss caused by material spillage. Its flexible mobility allows the device to quickly respond to different testing needs, shortening test preparation time and improving testing efficiency. The stable support structure ensures the reliable operation of the device under various working conditions, reduces the safety risks caused by device instability, and provides a strong guarantee for the smooth progress of testing.

[0067] In some embodiments, the receiving device 160 may further include: two side baffles 164, such as Figure 12 , Figure 13As shown, the side baffles 164 are rectangular plate-shaped structures that can be installed on the side walls of both sides of the hopper 161 and extend upwards to prevent material spillage. The side baffles 164 can also be rectangular plate-shaped structures made of high-strength and lightweight alloy plates to ensure sufficient strength to withstand material impact. The side baffles 164 can be fixed to the side walls of the hopper 161 by welding or bolting. If welding is used, continuous welding is performed at the contact edges between the side baffles 164 and the side walls of the hopper 161 to ensure a firm connection and form a unified structure that can effectively withstand material impact. If bolting is used, mounting holes are pre-drilled at corresponding positions on the side baffles 164 and the side walls of the hopper 161, and high-strength bolts and nuts are used for fastening. This method facilitates the disassembly and replacement of the side baffles. The vertically upward-extending structure effectively blocks materials that splash or slide upwards or sideways during the receiving process due to inertia or collision, greatly reducing the risk of material spillage and improving the integrity of material collection.

[0068] In this embodiment, by providing side baffles 164 on both sides of the hopper 161, materials can be effectively intercepted, preventing them from overflowing from both sides of the hopper 161. This ensures that all materials are collected inside the hopper 161, reducing material spillage and lowering manual cleaning costs and material loss. When the material trajectory is irregular, the side baffles 164 can guide the material, directing it towards the center of the hopper, assisting the front side plate in efficiently collecting the material. This prevents materials from overflowing outside the testing area, avoiding accidental impacts to operators or surrounding equipment, and ensuring a safe working environment at the testing site.

[0069] In some embodiments, such as Figure 12 , Figure 13 As shown, the receiving device 160 may further include: a bearing housing 165 and a rotating shaft 166.

[0070] The bearing housing 165 can be fixedly mounted on the upper front side of the base bracket 162; the rotating shaft 166 can be fixed below the front side plate and can pass through the bearing housing 165, allowing the hopper 161 to pour material around the rotating shaft 166. The bearing housing 165 can be made of high-strength cast iron and can have a semi-enclosed U-shaped structure. The bearing housing 165 is provided with multiple positioning holes and mounting holes. The positioning holes are used for precise positioning with the base bracket 162, and the mounting holes are used for bolt fixing, ensuring that the bearing housing is firmly mounted on the upper front side of the base bracket 162. The rotating shaft 166 can be connected to a bushing below the front side plate. In fact, the bushing can be integrated with the front side plate, either by welding or other means, to ensure that the rotating shaft 166 is firmly connected to the hopper 161, allowing the hopper 161 to rotate flexibly around the rotating shaft 166. After the material is collected, it needs to be transported to the designated unloading area. Multiple lifting rings can be installed on the rear arm of the hopper 161 and the bottom support 162. The hopper can be flipped up along the rotation axis 166 by the overhead crane holding the lifting rings of the hopper 161 to complete the unloading.

[0071] In this embodiment of the present disclosure, by setting a bearing seat 165 and a rotating shaft 166, when unloading is required, the rear side of the hopper 161 can be lifted, and the hopper 161 can automatically tilt around the rotating shaft 166 as the axis to quickly pour the material to the designated position. The unloading process can be completed quickly, reducing the force required for the operator to pour the material. Even if the hopper is full, the unloading operation can be easily completed, which is convenient and fast.

[0072] In some embodiments, such as Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, the material throwing test device 100 may further include: a stand 170, which can be set below the test bracket 110 and can be used to adjust the height of the test bracket 110. The stand 170 can be fixedly connected to the test bracket 110, which can be fixed by bolts, clips, etc. The stand 170 can be set as a foot cup to adjust the height of the test bracket 110. Connecting seats with mounting holes can be welded to the four corners of the bottom of the test bracket 110, and the top of the cup body is fixedly connected to the connecting seats by bolts to ensure a firm connection. The adjusting screw passes through the cup body and the anti-slip base. By rotating the adjusting screw, the overall height of the foot cup can be raised or lowered. After adjusting to a suitable height, tighten the locking nut to fix the adjusting screw to the cup body to prevent the screw from loosening during use and to ensure the stability of the test bracket 110. The foot cup can adjust the vertical height of the test bracket 110, which can eliminate the error caused by uneven bottom surface on the test results and ensure the shooting accuracy of the camera 131.

[0073] In this embodiment of the present disclosure, by setting a tripod 170 below the test bracket 110, the height of the test bracket 110 in the vertical direction can be adjusted to adapt to uneven ground conditions on site, and the shooting accuracy of the camera 131 can be ensured. This allows the camera 131 to clearly record the posture changes of materials at different stages during the process of throwing materials in different forms, which can provide a high-quality data foundation for subsequent image analysis of material posture stability and provide a basis for subsequent judgment on whether the material spreading process meets the sorting requirements.

[0074] Based on the same inventive concept, exemplary embodiments of this disclosure also provide a material throwing test device, wherein, as Figure 1 , Figure 2 As shown, the material throwing test equipment may include: a material throwing component 200, such as the material throwing test device 100 in the aforementioned embodiment.

[0075] Material throwing assembly 200, such as Figure 14 , Figure 15 , Figure 16 As shown, it can be used to throw materials. The throwing assembly 200 can be directly fed by a vibrating feeder, or it can be a sluice box throwing fixture, roller throwing fixture, belt throwing fixture, etc., which can ensure that the thrown material is evenly scattered. If a sluice box throwing fixture, roller throwing fixture, belt throwing fixture, etc. are used, the material can be fed by the vibrating feeder at the top instead of being directly thrown by the vibrating feeder. There will be no amplitude, and the instantaneous position of the material leaving the feeder will not be different. During the subsequent falling process, the horizontal deviation of the material from the camera position will not be large as time increases. At the same time, the tumbling of the material during the falling process can also be effectively avoided.

[0076] Material throwing test device 100, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, one side of the throwing component 200 can be set to record the posture of the thrown material. The throwing test device 100 is equipped with a camera component 130 and a light source component 120, so that the camera component 130 can clearly record the posture changes of the material at different stages during different throwing processes. This provides a high-quality data foundation for subsequent image analysis of the material's posture stability and provides a basis for judging whether the material distribution process meets the sorting requirements. Furthermore, the camera component 130 and the light source component 120 can be flexibly installed, allowing for flexible adjustment of the illumination angle of the light source 121 and the shooting angle of the camera 131 according to different throwing methods and different movement trajectories of the material. This ensures that the camera 131 can capture the posture of the material, meeting the testing needs of diverse material distribution schemes and improving the versatility of the throwing test device 100.

[0077] In some embodiments, such as Figure 14 , Figure 15 , Figure 16 , Figure 17 , Figure 18 As shown, the material throwing assembly 200 may include: a material throwing bracket 210, a material throwing device 220, and a camera position guide 230.

[0078] Material throwing bracket 210, such as Figure 14 , Figure 15 , Figure 16 , Figure 17 , Figure 18 As shown, it can be made of high-strength materials, such as aluminum or steel. The throwing bracket 210 can include multiple horizontal and vertical beams, and can mount the throwing device 220 and camera position guide 230. The multiple horizontal and vertical beams can be moved in position, and can be equipped with slide rails for movement, allowing the throwing bracket 210 to quickly adjust its structural layout and adapt to different throwing test scenarios.

[0079] The material throwing device 220 can be installed on the upper part of the material throwing bracket 210 and can be used to throw materials. The material throwing device 220 can be set on the upper part of the material throwing bracket 210. It can be used for direct feeding from a vibrating feeder, or it can be a sluice box throwing fixture, roller throwing fixture, belt throwing fixture, etc., ensuring that the thrown material is evenly distributed. The vibrating feeder can consist of an electromagnetic vibrator, a trough, and damping springs. The material is thrown by high-frequency vibration of the trough driven by electromagnetic force. The sluice box throwing fixture can include an inclined sluice, a material guide chute, and an adjustable-angle bracket. The material is conveyed to the top of the sluice by the vibrating feeder and then slides down the smooth surface of the sluice by gravity and is thrown out. If sled throwing fixtures, roller throwing fixtures, or belt throwing fixtures are used, the material can be fed by an upper vibrating feeder instead of being directly thrown by the vibrating feeder. This avoids amplitude generation, and the instant the material leaves the feeder, there will be no discrepancy in its position. During the subsequent descent, the material's horizontal distance from the camera position will not deviate significantly over time, and the tumbling of the material during descent can be effectively avoided. Roller throwing fixtures can consist of a powered roller assembly, a tensioning device, and a material carrying tray. The rollers rotate synchronously via belt drive, accelerating the material on the tray and throwing it out. Belt throwing fixtures can integrate a drive motor, a circular conveyor belt, and a material baffle, controlling the initial velocity of the material by adjusting the belt speed.

[0080] Camera position guide bracket 230, such as Figure 14 , Figure 15 , Figure 16As shown, it can be installed on the throwing bracket 210, or positioned below the throwing device 220, and can be used to assist in the installation of the camera assembly 130. The camera position guide 230 can be an L-shaped metal frame, serving as an auxiliary tooling. When the second camera 131 is suspended in the air, making camera 131 calibration inconvenient, the camera position guide 230 can extend from the throwing bracket 210. The position of the second camera 131 can be calculated based on different material placement methods and speeds, thus facilitating camera and optical engine calibration. Whether changing the height or position of the throwing device 220, or adjusting the test space layout, the camera position guide 230 can be adjusted to ensure the camera is always in a precise shooting position, improving the flexibility and versatility of the entire throwing test device 100.

[0081] In this embodiment, by setting up a material throwing bracket 210, a material throwing device 220, and a camera position guide frame 230, the instantaneous position of the material leaving the feeder will not have a discrepancy. During the subsequent descent, the material's horizontal distance from the camera position will not deviate significantly over time, and the tumbling of the material during descent can also be effectively avoided. Furthermore, whether changing the height or position of the material throwing device 220, or adjusting the spatial layout of the test, the camera position guide frame 230 can be adjusted to ensure that the camera is always in a precise shooting position, improving the flexibility and versatility of the entire material throwing test device 100. This allows the camera assembly 130 to clearly record the posture changes of the material at different stages during different forms of throwing, providing a high-quality data foundation for subsequent image analysis of material posture stability and providing a basis for subsequent judgment on whether the material distribution process meets the sorting requirements. Furthermore, the camera assembly 130 and the light source assembly 120 can be flexibly installed, allowing for flexible adjustment of the illumination angle of the light source 121 and the shooting angle of the camera 131 according to different material throwing methods and different material movement trajectories. This ensures that the camera 131 can capture the posture of the material, meeting the testing needs of diverse fabric solutions and improving the versatility of the material throwing test device 100.

[0082] In some embodiments, such as Figure 14 , Figure 15 , Figure 16 As shown, the material throwing device 220 may include a buffer assembly 221 and a slide assembly 222.

[0083] Buffer component 221, such as Figure 14 , Figure 15 , Figure 16As shown, it can be installed on the upper part of the material throwing bracket 210 to receive and buffer materials. The buffer assembly 221 can be made of high-strength stainless steel and has a cuboid structure with an open top. It can be bolted to the material throwing brackets 210 on both sides. Side baffles can be provided on both sides of the buffer assembly 221 to prevent material spillage. The buffer assembly 221 can use flexible materials such as rubber or scraper cloth to buffer the impact force of the material. Side baffles 223 can also be provided on both sides of the buffer assembly 221. The side baffles 223 can extend upward to prevent materials from being ejected from the sides during the fall.

[0084] Slide assembly 222, such as Figure 14 , Figure 15 , Figure 16 As shown, the chute assembly 222 can be tilted below the buffer assembly 221 and fixed to the material throwing bracket 210. It can be used to receive and discharge the material from the buffer assembly 221. The chute assembly 222 can be made of smooth stainless steel plate, with an angle of 30° to 45° to the horizontal direction, ensuring smooth material descent. The chute assembly 222 can be positioned below the buffer assembly 221 and fixed to the material throwing bracket 210 by bolts, clips, etc. The adjustable bracket of the chute assembly 222 supports fine-tuning of the angle, enabling precise control of the initial velocity and trajectory of the material, adapting to different testing scenarios, and adjusting the material to achieve a suitable descent speed. The chute assembly 222 can receive the material from the buffer assembly 221 and throw it out.

[0085] In this embodiment, by setting up a buffer component 221 and a slide component 222, the material is first buffered by the buffer component 221, and then slides down to the slide component 222. This can maintain the stability of the material's posture, ensure that the material reaches a suitable sliding speed, maintain the stability of the material's posture, prevent collisions between materials, keep the horizontal distance between the material and the camera position consistent, and ensure a balanced falling speed. This can improve the output of material sorting, facilitate the recording of different throwing patterns and different movement trajectories of the material, and allow for flexible adjustment of the illumination angle of the light source 121 and the shooting angle of the camera 131. This can ensure that the camera 131 can capture the posture of the material, meet the testing requirements of diverse material laying schemes, and improve the versatility of the throwing test device 100.

[0086] In some embodiments, such as Figure 19 , Figure 20 As shown, the buffer assembly 221 may include: rubber 2211, horizontal part 2212, vertical part 2213, and pressure plate 2214.

[0087] Rubber 2211, such as Figure 19 , Figure 20As shown, it can be used to receive materials. The horizontal section 2212 may be provided with elongated holes. The horizontal section 2212 can be fixed to multiple positions along the horizontal direction of the material throwing bracket 210 by a second fixing bolt. The horizontal section 2212 is a rectangular plate. Multiple elongated holes are evenly distributed on the plate surface. The length direction of the elongated holes is consistent with the horizontal direction of the material throwing bracket 210, and the hole width is slightly larger than the diameter of the second fixing bolt, providing adjustment space for the installation of the horizontal section. The elongated holes of the horizontal section 2212 can adjust the movement of the buffer assembly 221 in the left and right directions.

[0088] Vertical part 2213, such as Figure 19 , Figure 20 As shown, it can be fixedly connected to the horizontal part 2212 and extend upwards, and can be used to fix the rubber 2211. It also uses a steel plate of the same thickness as the horizontal part, and can be integrally formed with the horizontal part 2212, vertically welded to one end of the horizontal part 2212 and extending upwards. The height of the vertical part 2213 is designed according to actual needs, and its outer surface is machined with multiple threaded holes for installing the pressure plate 2214 and fixing the rubber 2211.

[0089] Pressure plate 2214, such as Figure 19 , Figure 20 As shown, it can be a rectangular plate structure. The pressure plate 2214 can be used to fix the rubber 2211 to the vertical part 2213 via a third fixing bolt. The length of the pressure plate 2214 can match that of the vertical part 2213. A through hole is provided on the pressure plate corresponding to the threaded hole position of the vertical part 2213. The third fixing bolt passes through the through hole to fasten the pressure plate 2214 to the vertical part 2213, thereby firmly clamping the rubber 2211 between the pressure plate 2214 and the vertical part 2213.

[0090] The horizontal section 2212 can be connected to the horizontal beam of the material throwing bracket 210 via a second fixing bolt passing through its elongated hole. Due to the elongated hole, the horizontal section 2212 can be adjusted horizontally on the beam; once adjusted, tightening the second fixing bolt secures it. The vertical section 2213 and the horizontal section 2212 are welded together to form an integral L-shaped structure. The pressure plate 2214 presses against the rubber sheet from the outside. The third fixing bolt passes sequentially through the through hole on the pressure plate 2214, the rubber sheet 2211 (with pre-drilled small holes at corresponding positions), and is tightened into the threaded hole on the vertical section 2213, firmly fixing the rubber sheet to the vertical section 2213.

[0091] In this embodiment, the rubber sheet 2211 effectively reduces the impact of falling materials through its own elastic deformation, protecting the materials from damage, especially suitable for fragile and delicate materials. The adjustable design of the horizontal part 2212 allows the buffer assembly to be flexibly adjusted according to different positions and throwing trajectories of the throwing device 220, ensuring that the materials fall accurately onto the rubber sheet and improving buffering efficiency. The combined structure of the vertical part 2213 and the rubber sheet 2211 not only buffers the materials but also guides them, causing them to slide into the slide assembly 222 in a preset direction. This ensures smooth material conveying, maintains material stability, ensures appropriate sliding speed, and prevents collisions. It also maintains a consistent horizontal distance between the materials and the camera position, resulting in a balanced falling speed, increased material sorting output, and facilitates recording different throwing patterns and different movement trajectories of the materials.

[0092] In some embodiments, such as Figure 21 , Figure 22 , Figure 23 As shown, the slide assembly 222 may include: a bracket 2221, an arc-shaped guide head 2222, and multiple slide channels 2223.

[0093] Bracket 2221, such as Figure 21 , Figure 23 As shown, it can be a rectangular frame structure and can be fixedly mounted on the throwing bracket 210. The bracket 2221 can be welded from high-strength aluminum alloy profiles and can be a rectangular frame structure. Multiple mounting holes are provided on the sides and bottom of the frame for fixed connection with the throwing bracket 210 and for mounting the slide channel 2223.

[0094] Arc-shaped guide head 2222, such as Figure 21 , Figure 23 As shown, a material throwing bracket 210 can be installed, with an arc-shaped upper end, to receive and discharge the material discharged from the buffer assembly 221. The arc-shaped guide head 2222 is stamped from stainless steel sheet, with a smooth arc-shaped upper end to ensure smooth material flow. Ear plates with bolt holes on both sides of the arc-shaped guide head 2222 are used for fixing to the material throwing bracket 210. The arc-shaped guide head 2222 can also be welded from a round tube, which can decelerate the rapidly falling material by changing its direction via an arc before it enters the chute channel 2223.

[0095] Multiple slide channels 2223, such as Figure 21 , Figure 22 , Figure 23As shown, the material can be arranged side-by-side on one side of the bracket 2221 to receive and discharge the material discharged from the arc-shaped guide head 2222. Multiple chute channels 2223 can be provided, and the material's speed is slowed to approximately uniform when entering the chute channels 2223. The chute channels 2223 ensure that the material's posture does not change during the sliding process. The angle of the chute channels 2223 can be changed to adjust the material's sliding speed. The bracket 2221 is fixedly connected to the crossbeam and vertical beam of the throwing bracket 210 by bolts passing through mounting holes on its sides and bottom. Rubber pads are added at the connection points to reduce vibration transmission. The arc-shaped guide head 2222 is fixed to the top crossbeam of the throwing bracket 210 by bolts through bolt holes on the ear plate, ensuring a stable installation. The side plate of the sluice channel 2223 is connected to the mounting holes on the side of the bracket 2221 by bolts, and the bottom plate is fixed to the support structure at the bottom of the bracket 2221 by clips or bolts, which facilitates adjustment of the tilt angle of the sluice channel. The discharge port of the arc-shaped guide head 2222 is connected to the inlet of the sluice channel 2223 to form a continuous material conveying channel.

[0096] In this embodiment, a bracket 2221, an arc-shaped guide head 2222, and multiple chute channels 2223 are provided. Material can slide from the buffer assembly 221 to the chute assembly 222, and then slide out through the chute channels 2223 within the chute assembly 222. The arc structure of the arc-shaped guide head 2222 decelerates the rapidly falling material by changing its direction, before it enters the chute channels 2223. The tilt angle of the chute channels 2223 is adjustable to accommodate different types and flow rates of material, meeting diverse material throwing test requirements and adjusting the material to achieve a suitable falling speed. This ensures the material maintains a stable posture, achieves a suitable falling speed, maintains a stable posture without collisions, keeps the horizontal distance between the material and the camera position consistent, and ensures a uniform falling speed. This improves material sorting output and facilitates recording different throwing patterns and different movement trajectories of the material.
