Description

Technical Field

[0001] This utility model belongs to the field of shrimp fillet production technology, and relates to a shrimp fillet bagging detection device, particularly a residual metal detection device for shrimp fillet bagging detection. Background Technology

[0002] After processing, shrimp steaks need to be packaged and sealed. However, even after sealing, it's impossible to guarantee that the product is free of any metal impurities. In recent years, as people have become increasingly concerned about food safety, testing packaged products to prevent metal impurities from being mixed into the food or packaging during processing has become an essential process in the food industry.

[0003] A search revealed a metal detection device for packaged shrimp products disclosed in Chinese patent literature [Application No.: CN201821878731.6; Publication No.: CN209215345U]. This metal detection device includes a support platform with a conveying device on it. The conveying device passes through four metal detection boxes, and a flip-plate device is provided between the front and rear metal detection boxes. Each metal detection box has a defective product box and a lifting push plate device on the outside of its discharge end. The discharge end of the conveying device has a finished product box. A control box is located on the outside of the support platform.

[0004] Although the metal detection device for packaged shrimp products disclosed in this patent separates unqualified products from qualified products through a discharge box and a lifting push plate device, the detection device requires flipping the shrimp racks for detection by a flip plate, which is inefficient. Furthermore, the flipping and pushing process can easily damage the finished shrimp racks, increasing the production cost and scrap rate of the shrimp racks. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a residual metal detection device for shrimp fillet bagging. The technical problem this invention aims to solve is: how to achieve efficient double-sided metal detection of shrimp fillets after bagging, while ensuring rapid separation of high-quality products.

[0006] The objective of this utility model can be achieved through the following technical solutions: A residual metal detection device for shrimp fillet bagging includes a frame, multiple conveying rollers rotatably connected above the frame, a drive motor for driving the conveying rollers, a detection box fixedly installed above the frame, and an operating button fitted onto the surface of the detection box. An electric push rod is fixedly installed below the frame, with the electric push rods located on both sides of the frame. A side frame is fixedly installed at the output end of the electric push rod, located below the frame. A rotating rod is rotatably connected to the inner side of the side frame, and a gear disk is fixedly installed on the outer wall of the rotating rod. A side plate is fixedly installed at the end of the rotating rod away from the side frame. Conveying cylinders are rotatably connected to the inner sides of both ends of the side plate. A conveyor belt is meshed with the outer wall of the conveying cylinder, and one of the conveying cylinders is driven by an electric motor. A detection plate is fixedly installed between the two side plates, and the detection plate is located inside the conveyor belt. The outer wall of the gear disk is movably connected to a toothed plate, which is fixedly installed below the frame.

[0007] Using the above structure, the conveyor rollers rotate via a drive motor, causing the bagged shrimp fillets to move along them. A detection box located above the frame detects metal in the bagged shrimp fillets using an internal coil. This is existing technology and will not be elaborated further. To achieve double-sided detection of the bagged shrimp fillets, a detection plate is fixedly installed on the inner side of the side plate. This plate detects metal inside the conveyor belt from below. If no metal is detected inside the shrimp fillet, the conveyor cylinder rotates synchronously via an electric motor, moving the conveyor belt. The conveyor rollers and conveyor belt then sequentially detect metal in the bagged shrimp fillets. When metal is detected, the drive motor and... When the electric motor stops, the conveyor rollers and conveyor belt cease transporting the shrimp fillets. The bagged shrimp fillets containing metal objects remain on the surface of the conveyor belt. The electric push rod retracts, causing the side frame to move downwards via a rotating rod. This causes the side plate to move downwards within the frame. After the conveyor belt descends, a toothed plate is fixedly installed below the frame. Under the fixing action of the toothed plate, a gear disc meshes and rotates on its surface. The rotating rod, fixedly connected to the gear disc, causes the side plate to rotate inside the side frame. This causes the conveyor belt to tilt below the frame, unloading the substandard shrimp fillets. After unloading, the electric push rod drives the conveyor belt upwards in the reverse direction to reset it, facilitating subsequent inspection.

[0008] The conveyor belt is fitted inside the frame and is located below the inspection box. The surface of the conveyor belt is at the same level as the top of the conveyor roller.

[0009] By adopting the above structure and setting the conveyor belt and conveyor rollers at the same level, the bagged shrimp cutlets can be stably conveyed on the surface of the conveyor belt and conveyor rollers. This ensures that the detection box can detect the moving shrimp cutlets from a fixed position above. Furthermore, by setting a detection plate inside the conveyor belt and placing the detection plate below the detection box, the bagged shrimp cutlets are simultaneously and accurately detected by bidirectional metal detection as they move to the surface of the conveyor belt. Compared with the existing flipping detection, this method is more efficient and avoids damage to the shrimp cutlets, thus ensuring the formation rate of the shrimp cutlets.

[0010] The frame has a slot on top that can accommodate the lifting and lowering movement of the rotating rod and gear disc, and a toothed plate is fixedly connected to one side of the slot. The toothed plate is engaged on one side of the gear disk, and the upper section of the toothed plate does not have tooth grooves.

[0011] By adopting the above structure and setting a slot on the top of the frame, the rotating rod and gear disk are precisely installed, ensuring the movement space of the gear disk and avoiding interference of the frame with the rotating rod. This facilitates the side frame to drive the side plate to be fitted and installed inside the frame through the rotating rod, and enables the bagged shrimp racks to move precisely on the surface of the conveyor roller and conveyor belt.

[0012] The output end of an electric motor is fixedly installed at one end of the conveying cylinder, and the electric motor is fixedly installed on the outer wall of the side plate. The side plates are arranged parallel to each other on the inner side of the side frame.

[0013] By adopting the above structure and installing an electric motor, the conveyor cylinder is precisely driven, which facilitates the movement of the conveyor cylinder and the conveyor belt, enabling the shrimp racks to move below the detection box and ensuring the detection efficiency and movement effect of the bagged shrimp racks.

[0014] The toothed plate and the electric push rod are arranged parallel to each other, and the toothed plate is arranged corresponding to the gear disks on both sides.

[0015] With the above structure, the parallel arrangement of the toothed plate and the electric push rod allows the side frame to move downwards when the electric push rod drives it. Simultaneously, the side frame drives the gear disc to mesh and connect on the outer wall of the toothed plate, achieving precise meshing and rotation of the gear disc on the outer wall of the toothed plate. This facilitates the side plate as a whole driving the conveyor belt to tilt and unload materials.

[0016] Compared with the prior art, the residual metal detection device for shrimp fillet bagging detection of this utility model has the following advantages: In this invention, by lifting and lowering side plates and detection plates inside the frame, the detection plates and detection boxes can simultaneously perform metal detection on bagged shrimp fillets from both sides, resulting in higher detection efficiency and avoiding the flipping and damage of the shrimp fillets during the detection process, thus ensuring the quality of the shrimp fillets. At the same time, by fixing a gear disk to the outer wall of the rotating rod, the meshing action of the gear disk and the toothed plate allows the conveyor belt to rotate after descending, facilitating the conveyor belt to unload unqualified shrimp fillets from the surface. This achieves efficient discharge of unqualified shrimp fillets, ensuring the classification quality of superior products. Furthermore, the structure is simple, the detection accuracy is high, and the working efficiency is high. Attached Figure Description

[0022] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments. Example

[0023] like Figures 1-4 As shown; A residual metal detection device for shrimp fillet bagging includes a frame 1, multiple conveyor rollers 2 rotatably connected above the frame 1, a drive motor 3 for driving the conveyor rollers 2, a detection box 4 fixedly installed above the frame 1, an operating button 5 fitted onto the surface of the detection box 4, an electric push rod 6, a side frame 7, a rotating rod 8, a gear disk 9, a side plate 10, a conveyor cylinder 11, an electric motor 12, a conveyor belt 13, a detection plate 14, and a toothed plate 15. The electric push rod 6 is fixedly installed below the frame 1, and is located on both sides of the frame 1. The electric push rod 6... A side frame 7 is fixedly installed at the output end, located below the frame 1. A rotating rod 8 is rotatably connected to the inner side of the side frame 7, and a gear disk 9 is fixedly installed on the outer wall of the rotating rod 8. A side plate 10 is fixedly installed at the end of the rotating rod 8 away from the side frame 7, and the side plate 10 is arranged parallel to the inner side of the side frame 7. Both ends of the side plate 10 are rotatably connected to conveyor cylinders 11. A conveyor belt 13 is meshed with the outer wall of the conveyor cylinder 11, and one of the conveyor cylinders 11 is driven by an electric motor 12. Specifically, the output end of the electric motor 12 is fixedly installed at one end of the conveyor cylinder 11, and the electric motor... The conveyor roller 12 is fixedly installed on the outer wall of the side plate 10. The installation of the electric motor 12 enables precise driving of the conveyor cylinder 11, facilitating the movement of the conveyor belt 13 and allowing the shrimp racks to move below the detection box 4. This ensures the efficiency of the bagged shrimp rack detection and the movement effect. Simultaneously, a detection plate 14 is fixedly installed between the two side plates 10, located inside the conveyor belt 13. The conveyor belt 13 is fitted inside the frame 1 and located below the detection box 4. Furthermore, the surface of the conveyor belt 13 is flush with the top of the conveyor roller 2. With the conveyor belt 13 and conveyor roller 2 set at the same horizontal level, the bagged shrimp strips can be stably conveyed on the surface of the conveyor belt 13 and conveyor roller 2, ensuring that the detection box 4 can detect the moving shrimp strips at a fixed position above. Moreover, by setting the detection plate 14 inside the conveyor belt 13 and setting the detection plate 14 below the detection box 4, the bagged shrimp strips are simultaneously and accurately detected by bidirectional metal when they move to the surface of the conveyor belt 13. Compared with the existing flipping detection, the working efficiency is higher, and damage to the shrimp strips is avoided, ensuring the forming rate of the shrimp strips. Furthermore, a toothed plate 15 is movably meshed with the outer wall of the gear disk 9. The toothed plate 15 is fixedly installed below the frame 1. A slot is provided on the upper part of the frame 1 to accommodate the lifting and lowering movement of the rotating rod 8 and the gear disk 9. The toothed plate 15 is fixedly connected to one side of the slot. The toothed plate 15 is meshed with one side of the gear disk 9. The upper part of the toothed plate 15 does not have tooth grooves. By providing a slot on the upper part of the frame 1, the rotating rod 8 and the gear disk 9 are precisely installed, ensuring the movement space of the gear disk 9 and avoiding interference of the frame 1 with the rotating rod 8. This facilitates the side frame 7 to drive the side through the rotating rod 8. Plate 10 is fitted inside the frame 1, enabling precise movement of the bagged shrimp racks on the surfaces of the conveyor roller 2 and conveyor belt 13. The toothed plate 15 is set parallel to the electric push rod 6, and the toothed plate 15 is set with corresponding gear discs 9 on both sides. Through the parallel setting of the toothed plate 15 and the electric push rod 6, when the electric push rod 6 drives the side frame 7 to move downward, the side frame 7 simultaneously drives the gear discs 9 to mesh and connect on the outer wall of the toothed plate 15. This achieves precise meshing and rotation of the gear discs 9 on the outer wall of the toothed plate 15, which facilitates the side plate 10 as a whole to drive the conveyor belt 13 to tilt and unload the material.

[0024] The working principle of this utility model is as follows: During operation, the drive motor 3 drives the conveyor roller 2 to rotate, causing the bagged shrimp to move along the conveyor roller 2. With the detection box 4 positioned above the frame 1, the detection box 4 uses an internal coil to detect metal in the bagged shrimp. This is existing technology and will not be elaborated further. To achieve double-sided detection of the bagged shrimp, a detection plate 14 is fixedly installed on the inner side of the side plate 10. The detection plate 14 detects metal in the bagged shrimp from below inside the conveyor belt 13. When no metal is detected inside the shrimp, the conveyor cylinder 11 is simultaneously rotated by the electric motor 12, driving the conveyor belt 13 to move. The conveyor roller 2 and the conveyor belt 13 then sequentially detect metal in the bagged shrimp. When a metal object is detected, the drive motor 3 and the electric motor 12 stop, causing the conveyor roller 2 and the conveyor belt 13 to move. Belt 13 does not convey shrimp fillets. Shrimp fillets with metal objects are placed on the surface of conveyor belt 13. When electric push rod 6 retracts, side frame 7 moves side plate 10 downward via rotating rod 8. This causes side plate 10 to move conveyor belt 13 downward inside frame 1. After conveyor belt 13 descends, toothed plate 15 is fixedly installed below frame 1. Under the fixing action of toothed plate 15, gear disk 9 meshes and rotates on the surface of toothed plate 15. Through the fixed connection between rotating rod 8 and gear disk 9, side plate 10 drives conveyor belt 13 to rotate inside side frame 7. This causes conveyor belt 13 to tilt below frame 1 to unload unqualified shrimp fillets. After unloading, electric push rod 6 drives conveyor belt 13 upward in the reverse direction to reset it, facilitating subsequent testing. This completes the working principle of the residual metal detection device for shrimp fillet bagging inspection.
