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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figure 1 - Figure 3 As shown, this utility model is a chain plate type wood pulp conveyor with metal detection function, including plate 1, two plate 1 are arranged symmetrically, a conveyor belt 2 is installed between the two plate 1, and an adjustment mechanism is provided between the conveyor belt 2 and the plate 1 for adjusting the detection range and collecting metal debris. The adjustment mechanism includes a fixed plate 3 mounted on a plate 1. A motor 4 is fixed to one side of the fixed plate 3. A lead screw 5 is fixedly connected to the output end of the motor 4 through the fixed plate 3. A movable frame 6 is fixedly connected to the lead screw 5 via a ball nut. The lead screw 5 passes through the movable frame 6. Four electromagnets 7 are fixed in an array on the movable frame 6. A controller 18 is fixed to one side of the plate 1 and is electrically connected to the electromagnets 7. Support plates 8 are fixed to both sides of the movable frame 6 and are staggered. A protective shell 9 is fixed to the lower end of the support plate 8. A metal sensor 11 is fixed inside the protective shell 9. An alarm 10 is fixed to the upper end of the support plate 8. The controller 18 is electrically connected to the metal sensor 11 and the alarm 10. The protective shell 9 is a transparent acrylic sheet. A limiting post 14 is provided at the end of the movable frame 6 away from the lead screw 5. The limiting post 14 slides through the movable frame 6. A fixing block is fixed to one end of the limiting post 14, and a limiting block 13 is fixed to the end of the limiting post 14 away from the limiting block 13. Two symmetrical collection boxes 12 are fixed to one side of the two plates 1 by bolts, and the collection boxes 12 correspond to the electromagnets 7.
[0020] Specifically, when the conveyor belt 2 is in operation, the staff pours the wood pulp to be transported onto the conveyor belt 2. The conveyor belt 2 is a chain plate type conveyor belt 2, which facilitates the transport of wood pulp. The position of the metal sensor 11 can be easily adjusted through the adjustment mechanism to improve the detection range of the metal sensor 11, facilitate the cleaning of metal debris, reduce the number of manual cleanings, and reduce the impact on the wood pulp conveying efficiency. Specifically, the motor 4 rotates the lead screw 5, causing the ball nut to drive the moving frame 6 to reciprocate. The moving frame 6 slides on the limiting post 14, which restricts the movement of the moving frame 6 and drives the metal sensor 11 (KJT) to move. This adjusts the position of the metal sensor 11 (KJT), increasing the detection range and reducing the detection blind zone. Simultaneously, the moving frame 6 drives the electromagnet 7 to move, and the electromagnet 7 adsorbs and removes metal debris from the wood pulp, facilitating the cleaning of metal debris. Four electromagnets 7 perform two cleaning and removal processes on the metal debris in the wood pulp, reducing metal debris residue. The staggered arrangement of the metal sensors 11 (KJT) increases the detection range and reduces the detection blind zone. A transparent acrylic plate protects the metal sensors 11 (KJT), reducing the impact on them. Furthermore, when the metal sensor 11 (KJT)... When the electromagnet 7 fails to attract metal debris for cleaning, feedback is sent to the controller 18. The controller 18 then activates the alarm 10 and stops the conveyor belt 2. This allows staff to locate the metal debris based on the alarm position and perform manual cleaning, reducing the number of manual cleaning operations, improving cleaning efficiency, and minimizing the impact on wood pulp conveying efficiency. When the electromagnet 7 needs cleaning, the controller 18 stops the motor 4 when the electromagnet 7 enters the collection box 12, de-energizing the electromagnet 7 and causing the metal debris to fall into the collection box 12. To clean the collection box 12, the bolts on the collection box 12 are loosened to release the restriction on the collection box 12, and the box is reset after cleaning.
[0021] In this embodiment, refer to Figure 1 - Figure 3 As shown, a hydraulic telescopic rod 17 is fixed to one side of the plate 1, and the telescopic end of the hydraulic telescopic rod 17 is fixedly connected to the fixed plate 3. A sliding column 16 is fixed to the lower end of the limiting block 13, and a limiting plate 15 is fixed to one side of the plate 1. The sliding column 16 slides through the limiting plate 15.
[0022] Specifically, operating the hydraulic telescopic rod 17 causes the fixed plate 3 to move, which in turn drives the moving frame 6 to rise and fall. This causes the limiting block 13 to drive the sliding column 16 to slide on the limiting plate 15, thus restricting the moving frame 6. This facilitates the adjustment of the height of the metal sensor 11 (KJT) and the electromagnet 7, improves the detection accuracy of the metal sensor 11 (KJT), enhances the cleaning effect of the electromagnet 7, and allows for the adjustment of the height of the moving frame 6 according to the thickness of the wood pulp being transported.
[0023] In this embodiment, refer to Figure 2 - Figure 4As shown, two symmetrical support legs 25 are fixed to the lower ends of the two plates 1. A motor 20 is fixed to one side of one of the support legs 25. The output end of the motor 20 passes through the support leg 25 and is fixedly connected to a cleaning column 21. Cleaning brushes 22 are fixed on the cleaning column 21 and arranged in an array. The cleaning brushes 22 are in contact with the conveyor belt 2. A scraper 23 is provided on one side of the cleaning brush 22 and is set at an angle. The scraper 23 is a flexible silicone plate and is in contact with the conveyor belt 2. The scraper 23 is fixedly connected to the support leg 25. A placement box 19 is fixed between the two support legs 25. A cleaning plate 24 is fixed inside the placement box 19 and is in contact with the cleaning brush 22. A baffle is fixed to one side of the placement box 19, and the baffle corresponds to the cleaning brush 22.
[0024] Specifically, the plate 1 is supported by the support leg 25. When the conveyor belt 2 is running, the cleaning brush 22 cleans the metal debris and other impurities on the conveyor belt 2, reducing the impact of impurities and debris on the quality of wood pulp. The motor 20 is turned to make the cleaning column 21 rotate, which improves the cleaning effect of the cleaning brush 22 on the conveyor belt 2 and reduces the residue of impurities and debris. Then, the scraper 23 performs a second scraping cleaning on the conveyor belt 2, which improves the cleaning effect and reduces the residue of impurities and debris. The cleaning plate 24 cleans the impurities and debris on the cleaning brush 22, reducing the impact on the cleaning effect of the cleaning brush 22. The cleaned impurities and debris fall into the placement box 19 through the baffle, which facilitates the collection of impurities and debris and facilitates the cleaning and operation of the conveyor belt 2.
[0025] The working principle of this utility model is as follows: when the conveyor belt 2 is running, the workers pour the wood pulp to be transported onto the conveyor belt 2. The conveyor belt 2 is a chain plate type conveyor belt 2, which supports the plate body 1 through the support legs 25 to facilitate the transport of wood pulp. Then, the motor 4 is operated, causing the lead screw 5 to rotate, which in turn causes the ball nut to drive the moving frame 6 to move back and forth. The moving frame 6 slides on the limiting post 14, which restricts the moving frame 6 and drives the metal sensor 11 (KJT) to move. This adjusts the position of the metal sensor 11 (KJT), increasing the detection range and reducing the detection blind zone. At the same time, the moving frame 6 drives the electromagnet 7 to move, and the electromagnet 7 is operated to adsorb and remove metal debris from the wood pulp, facilitating the cleaning of metal debris. The four electromagnets 7 clean and remove metal debris from the wood pulp twice, reducing metal debris residue. The staggered arrangement of the metal sensors 11 (KJT) increases the detection range and reduces the detection blind zone. The metal sensors 11 (KJT) are protected by a transparent acrylic plate to reduce the impact on the metal sensors 11 (KJT). At the same time, when the metal sensor 11 (KJT) When the electromagnet 7 fails to pick up the metal debris to be cleaned, it sends a signal to the controller 18. The controller 18 then activates the alarm 10 and stops the conveyor belt 2. This allows staff to locate the metal debris based on the alarm position and perform manual cleaning, reducing the number of manual cleaning operations and minimizing the impact on the wood pulp conveying efficiency. When the electromagnet 7 needs cleaning, the controller 18 stops the motor 4 when the electromagnet 7 enters the collection box 12, de-energizing the electromagnet 7 and causing the metal debris to fall into the collection box 12. Then, the hydraulic telescopic rod 17 is operated, causing the fixed plate 3 to move and the moving frame 6 to rise and fall. This causes the limiting block 13 to drive the sliding column 16 to slide on the limiting plate 15, thus restricting the moving frame 6. This facilitates the adjustment of the height of the metal sensor 11 (KJT) and the electromagnet 7, improving the detection accuracy of the metal sensor 11 (KJT) and the cleaning effect of the electromagnet 7. It also facilitates adjustment according to the transport thickness of the wood pulp. When the conveyor belt 2 is running, the cleaning brush 22 cleans the metal debris and other impurities on the conveyor belt 2, reducing the impact of impurities on the quality of the wood pulp. The motor 20 is operated, causing the cleaning column 21 to rotate, improving the cleaning effect of the cleaning brush 22 on the conveyor belt 2 and reducing the residue of impurities. Then, the scraper 23 performs a second scraping and cleaning of the conveyor belt 2, improving the cleaning effect and reducing the residue of impurities. The cleaning plate 24 cleans the impurities on the cleaning brush 22, reducing the impact on the cleaning effect of the cleaning brush 22. The cleaned impurities fall into the placement box 19 through the baffle, facilitating the collection of impurities.
