Description

Technical Field

[0001] This utility model relates to the field of material metal content detection technology, specifically a material metal content detection device. Background Technology

[0002] In the industrial production sector, the detection of metal content in materials is a key step in ensuring product quality and controlling the production process. For example, in scenarios such as ore sorting, scrap metal recycling, and food processing for detecting metal impurities, it is necessary to conduct rapid and accurate metal content analysis on batches of materials in order to achieve graded utilization or safety control.

[0003] However, existing detection devices still have certain problems in use:

[0004] For example, a metal detection device with application number CN202222368547.X includes a frame, a belt conveyor mounted on the frame, and a metal detection body disposed above the belt conveyor. The metal detection body is connected to one side of the frame, and the other side of the frame is provided with a pushing mechanism for pushing abnormal products to the outside of the frame and a collection box for receiving abnormal products. The pushing mechanism includes a push rod vertically disposed on one side of the frame and a driving mechanism for driving the push rod to rotate in the vertical direction and in the horizontal direction, so that the push rod can rotate from the vertical state to the horizontal state and rotate on the horizontal plane to push abnormal products out from the side. The collection box is detachably connected to the frame.

[0005] Traditional detection devices often rely on conveyor belts to directly transport materials through the detector. However, during the transmission process, the materials are prone to swaying due to vibration, irregular shape, or initial placement deviation. This can lead to misalignment between the material and the sensing area of ​​the detector, causing the intensity of the metal signal received by the sensor to decrease or fluctuate. Consequently, the detection data becomes distorted, which seriously affects product quality grading or process control.

[0006] In view of this, in-depth research was conducted on the above issues, which led to the creation of this case.

[0007] To address the aforementioned issues, an innovative design was developed based on the existing material metal content detection device. Utility Model Content

[0008] The purpose of this invention is to provide a material metal content detection device to solve the problem that the detection devices mentioned in the background art mostly rely on conveyor belts to directly transport materials through the detector. However, during the transmission process, the materials are prone to swaying due to vibration, irregular shape, or initial placement deviation, which leads to misalignment between the material and the sensing area of ​​the detector. This causes the intensity of the metal signal received by the sensor to decrease or fluctuate, resulting in distorted detection data and seriously affecting product quality grading or process control.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A material metal content detection device includes a frame and a detector. The detector is mounted on the top of the frame, and a display controller is mounted on the outside of the detector. A conveyor belt is mounted on the top of the frame and passes through the middle of the detector. Two sets of baffles are symmetrically mounted above the conveyor belt. A threaded rod is threaded through and threadedly connected to the middle of the two sets of baffles. A handwheel is fixed to the outer end of the threaded rod, and a back plate is provided at the other end of the threaded rod. A bearing is mounted on the rear side of the back plate, and the threaded rod is rotatably connected to the bearing. Four sets of limiting rollers are rotatably connected to the middle of the back plate. Limiting shafts are fixed on both sides of the back plate and are slidably connected to the middle of the baffles.

[0011] By adopting the above technical solution, the screw rod is driven to rotate by rotating the handwheel, and the back plate is moved under the constraint of the limiting shaft by the screw transmission. This allows the four sets of limiting rollers to form a dynamic clamping channel, which corrects the swaying trajectory of the material on the conveyor belt in real time, ensuring that the material passes through the sensing area of ​​the detector accurately. This avoids the attenuation or misjudgment of the metal content detection signal due to positional deviation. At the same time, the adjustable limiting structure adapts to the detection needs of materials with different widths.

[0012] Preferably, a support plate is fixed to one end of the frame, and the surface of the support plate is a smooth plane. A feed plate is fixed to both sides of the support plate, and the surface of the feed plate is a smooth inclined surface design.

[0013] By adopting the above technical solution, the smooth flat design of the bearing plate can reduce the frictional resistance during material feeding. Combined with the material feeding plates with smooth inclined surfaces on both sides, gravity guides the material to slide smoothly along a fixed path, avoiding accumulation or jamming. This enables automatic classification and export of materials after testing, ensuring that materials with different metal contents are quickly separated to designated areas. At the same time, the smooth surface facilitates cleaning and maintenance, improving the operating efficiency and reliability of the equipment.

[0014] Preferably, two sets of limiting blocks are fixed on the upper end surface of the bearing plate, and the distance between the two sets of limiting blocks corresponds to the distance between the two sets of baffles.

[0015] Using the above technical solution, the spacing between the two sets of limiting blocks matches the spacing of the baffles on the conveyor belt. When the material falls from the conveyor belt into the bearing plate, the limiting blocks further constrain the position of the material through physical blocking, ensuring that it falls accurately into the preset range, preventing the material from shifting due to inertia or collision during the transfer process, ensuring the accuracy of sorting after detection, while reducing the need for manual adjustment and improving the degree of automation.

[0016] Preferably, a fixing rod is fixed above the bearing plate, a sliding groove is provided on one side of the fixing rod, a motor is installed at one end of the fixing rod, a lead screw is movably connected to the output end of the motor, a slider is threadedly connected to the outer surface of the lead screw, and a sorting plate is fixed to the outer side of the slider.

[0017] Using the above technical solution, the motor drives the lead screw to rotate, and through the threaded transmission, the slider moves directionally along the chute, thereby controlling the horizontal reciprocating motion of the sorting plate on the carrier plate, realizing the automation of material sorting. Based on the detection results, materials with different metal contents are accurately pushed to the designated area, replacing manual sorting, improving sorting efficiency and accuracy, and adapting to the needs of high-frequency and continuous industrial production.

[0018] Preferably, the bottom of the frame is equipped with casters, and four sets of casters are evenly distributed along the bottom of the frame.

[0019] By adopting the above technical solution and installing four sets of casters on the frame, the equipment can be quickly moved or its position adjusted in the production workshop, increasing the ease of operation.

[0020] Preferably, the bottom of the frame is threaded with an adjusting screw, the bottom end of the adjusting screw is fixed with a foot, the outer surface of the adjusting screw is threaded with an adjusting nut, and four sets of feet are evenly distributed along the bottom of the frame.

[0021] By adopting the above technical solution, the adjusting screw is extended and retracted by rotating the adjusting nut, which drives the foot to move vertically. It can be adjusted independently to adapt to uneven ground. The self-locking characteristic of the thread is used to achieve precise adjustment and stable fixation of the frame height, ensuring that the equipment is placed horizontally. At the same time, it enhances the vibration resistance during the testing process and improves the testing accuracy and equipment stability.

[0022] Compared with the prior art, the beneficial effects of this utility model are: the material metal content detection device,

[0023] 1. Two sets of threaded rods are symmetrically installed on the two sets of baffles of the conveyor belt. The threaded rods are driven to rotate by rotating the handwheel. The threaded rods are connected to the back plate through bearings, which makes the back plate move. Under the action of four sets of limit shafts, the back plate can maintain a parallel or opposite translation. Four sets of limit rollers are installed in the middle of the back plate. When the material is conveyed by the conveyor belt, when the material comes into contact with the four sets of limit rollers, the limit rollers can correct the position of the material while ensuring accurate material transmission. This allows the material to maintain a certain trajectory during movement, preventing swaying and limiting the material on the conveyor belt to the sensing area of ​​the detector. This ensures that the material position is stable when detecting metal content, avoiding signal attenuation or false detection due to deviation. At the same time, it can adapt to the detection needs of materials with different widths, improving the versatility and detection accuracy of the equipment.

[0024] 2. After testing, the material falls onto the smooth surface of the support plate. Based on the test results of the material, the motor drives the lead screw to rotate in the corresponding direction, causing the slider connected to the outer surface threaded to move horizontally along the groove of the fixed rod, and driving the outer sorting plate to push the material to the corresponding feeding plate. The smooth inclined surface design of the feeding plate uses gravity to guide the material to slide out quickly, reducing residue and achieving efficient and accurate sorting of materials with different metal contents. At the same time, it reduces the risk of jamming and improves the stability and sorting efficiency of the equipment.

[0025] 3. Four sets of evenly distributed casters facilitate the rapid transfer of the equipment to the designated workstation within the production workshop. Upon arrival, rotating the adjusting nut drives the adjusting screw to extend or retract relative to the threaded hole at the bottom of the frame, causing the feet to move vertically. The four sets of feet can be independently adjusted in height to compensate for uneven ground. The self-locking characteristic of the threads forms stable support, eliminating the floating gap of the casters. This maintains the ease of equipment movement while ensuring the horizontal stability of the frame during testing, avoiding vibration interference with the accuracy of the testing instrument, and extending the service life of the casters, thus balancing flexibility and reliability.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Example 1

[0034] Please see Figures 1-3 This utility model provides a technical solution:

[0035] A material metal content detection device includes a frame 1 and a detector 2. The detector 2 is installed on the top of the frame 1, and a display controller 3 is installed on the outside of the detector 2. A conveyor belt 4 is installed on the top of the frame 1 and passes through the middle of the detector 2. Two sets of baffles 5 are symmetrically installed above the conveyor belt 4. A threaded rod 6 is threaded through and threadedly connected to the middle of the two sets of baffles 5. A handwheel 7 is fixed to the outer end of the threaded rod 6. A back plate 8 is provided at the other end of the threaded rod 6. A bearing 9 is installed on the rear side of the back plate 8, and the threaded rod 6 is rotatably connected to the bearing 9. Four sets of limiting rollers 10 are rotatably connected to the middle of the back plate 8. Limiting shafts 11 are fixed on both sides of the back plate 8 and are slidably connected to the middle of the baffles 5.

[0036] This material metal content detection device has two sets of threaded rods 6 symmetrically installed on the two sets of baffles 5 of the conveyor belt 4. The threaded rods 6 are driven to rotate by rotating the handwheel 7. The threaded rods 6 are connected to the back plate 8 through the bearing 9, which makes the back plate 8 move. Under the action of four sets of limiting shafts 11, the back plate 8 can maintain a lateral or opposite translation. Four sets of limiting rollers 10 are installed in the middle of the back plate 8. When the material is conveyed by the conveyor belt 4, when the material comes into contact with the four sets of limiting rollers 10, the limiting rollers 10 can correct the position of the material while ensuring accurate material transmission. This allows the material to maintain a certain trajectory during movement, preventing swaying and confining the material on the conveyor belt 4 within the sensing area of ​​the detector 2. This ensures that the material position is stable during metal content detection, avoids signal attenuation or false detection due to deviation, and adapts to the detection needs of materials of different widths, improving the versatility and detection accuracy of the equipment.

[0037] Example 2

[0038] Please see Figure 4 This utility model provides a technical solution:

[0039] A support plate 12 is fixed to one end of the frame 1, and the surface of the support plate 12 is a smooth plane. Feed plates 14 are fixed to both sides of the support plate 12, and the surface of the feed plates 14 is a smooth bevel design. Two sets of limiting blocks 13 are fixed to the upper surface of the support plate 12, and the spacing between the two sets of limiting blocks 13 corresponds to the spacing between the two sets of baffles 5. A fixing rod 15 is fixed above the support plate 12. A sliding groove 16 is provided on one side of the fixing rod 15. A motor 17 is installed at one end of the fixing rod 15. A lead screw 18 is movably connected to the output end of the motor 17. A slider 19 is threaded onto the outer surface of the lead screw 18. A sorting plate 20 is fixed to the outer side of the slider 19.

[0040] In this material metal content detection device, the detected material falls onto the smooth surface of the support plate 12. The two sets of limiting blocks 13 are spaced with the baffles 5 of the conveyor belt 4 to form a secondary positioning constraint, ensuring that the material slides down the preset path to the sorting area. According to the detection result of the material by the detector 2, the motor 17 drives the lead screw 18 to rotate. Its external thread cooperates with the threaded hole of the slider 19 to convert into linear motion, so that the slider 19 moves horizontally along the slide groove 16 of the fixed rod 15, driving the outer sorting plate 20 to push the material to the corresponding feeding plate 14. The smooth inclined surface design of the feeding plate 14 uses gravity to guide the material to slide out quickly, reducing residue and realizing efficient and accurate sorting of materials with different metal contents. At the same time, it reduces the risk of jamming and improves the stability and sorting efficiency of the equipment operation.

[0041] Example 3

[0042] Please see Figure 5 This utility model provides a technical solution:

[0043] The bottom of the frame 1 is equipped with casters 21, and four sets of casters 21 are evenly distributed along the bottom of the frame 1. The bottom of the frame 1 is threaded with an adjusting screw 22, the bottom end of the adjusting screw 22 is fixed with a foot 23, and the outer surface of the adjusting screw 22 is threaded with an adjusting nut 24, and four sets of foot 23 are evenly distributed along the bottom of the frame 1.

[0044] This material metal content detection device features four evenly distributed casters 21, facilitating rapid transfer of the equipment to designated workstations within the production workshop. Upon arrival, rotating the adjusting nut 24 drives the adjusting screw 22 to extend or retract relative to the threaded hole at the bottom of the frame 1, causing the feet 23 to move vertically. The four feet 23 independently adjust their height to compensate for uneven ground, forming stable support through the self-locking characteristic of the threads and eliminating the floating gap of the casters 21. This design maintains the ease of equipment movement while ensuring the horizontal stability of the frame 1 during testing, preventing vibration from interfering with the accuracy of the detector 2, and extending the service life of the casters 21, thus balancing flexibility and reliability.

[0045] Working principle:

[0046] In the detection stage, the rotating handwheel 7 drives the threaded rod 6 to rotate, which, through the transmission between the bearing 9 and the back plate 8, drives the limiting shaft 11 to slide within the baffle 5, so that the four sets of limiting rollers 10 form a dynamic clamping channel, correcting the sway of the material on the conveyor belt 4 and ensuring that it stably passes through the sensing area of ​​the detector 2. In the sorting stage, the detected material falls onto the smooth surface of the bearing plate 12, and the motor 17 drives the lead screw 18 to rotate, which, through the threaded transmission, causes the slider 19 to move horizontally along the slide groove 16, driving the sorting plate 20 to push the material to the inclined surface of the corresponding unloading plate 14, using gravity to achieve rapid diversion and discharge. In the deployment stage, the four sets of universal wheels 21 support the flexible movement of the equipment to the workstation, and rotating the adjusting nut 24 drives the adjusting screw 22 to extend and retract, so that the four sets of feet 23 can be independently leveled. The floating gap of the universal wheels 21 is eliminated by the threaded self-locking, and finally a closed-loop control of the entire process of detection-sorting-positioning is formed, taking into account material adaptability, sorting accuracy and equipment stability.
