Description

Technical Field

[0001] This utility model relates to the technical field of integrated metal inspection and weighing machines, specifically an integrated metal inspection and weighing machine. Background Technology

[0002] The metal detection and weighing integrated machine consists of a metal detection section, a weight sorting section, and a conveying and rejection device. The metal detection section is essentially the "gantry" of the metal detector, the core of metal detection. When an item containing metal passes through this "gantry," an alarm is triggered. The metal detector is composed of a control circuit and a coil. The coil generates a stable electromagnetic field. When a metal item passes through this stable magnetic field, the metal item cuts the magnetic field lines, disrupting the magnetic field balance and generating a tiny current change within the coil. This current change is amplified by a current amplification circuit, sampled and processed by a microprocessor, which then sends a command to the control output circuit to control the alarm. The system includes an optical alarm, a list of defective products, and the rejection of defective items. The weight sorting section consists of a weighing system with a weight sorting machine. The weighing system mainly uses weight sensors to detect the weight of the items. The range of the weight sensor determines the weighing range, and its accuracy is also closely related to the accuracy of the weight sensor. The weight sensor detects the weight and outputs a weight analog signal. This weight analog signal is recognized and processed by the internal DSP control unit. Then, it is compared with the set range to select qualified products and reject unqualified products. The system sends a command to the motor of the mechanical part to control whether to start the rejection device, records the information, and then displays the output.

[0003] A search revealed a metal inspection and weighing integrated machine with publication number CN 217474185 U, which relates to the field of metal inspection and weighing integrated machines. It includes a conveyor belt frame and a control cabinet. The conveyor belt frame is located on one side of the control cabinet. The upper outer surface of the conveyor belt frame is equipped with a metal detection mechanism, a weighing area, and a cylinder. The metal detection mechanism is located on one side of the weighing area. This metal inspection and weighing integrated machine, with its separate storage box, allows for product collection. During collection, the product is first pushed onto a flip-top cover. Then, the flip-top cover tilts under gravity via a connecting shaft, causing the product to slide off, thus preventing direct drop and damage. This avoids product waste. The connecting plate, driven by the push plate, cleans the conveyor belt with a cleaning brush, preventing debris from falling onto the conveyor belt surface and ensuring accurate equipment operation. The overall performance is better than traditional methods.

[0004] However, the aforementioned integrated machine still has some shortcomings in use. The metal detector is fixedly installed above the conveyor belt frame, and the detection height cannot be flexibly adjusted according to product specifications (such as thickness and volume), making it difficult to quickly adapt to diverse products, resulting in decreased detection accuracy or limited equipment applicability. At the same time, as a core component, the metal detector may need to be repaired or replaced due to malfunction or sensitivity decay after long-term use. However, the existing structure adopts a fixed installation method, and the disassembly process is cumbersome, requires tools, and is time-consuming, affecting the continuous operation of the production line. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an integrated metal detector and weighing machine. It solves the problem that metal detectors are fixedly installed above the conveyor belt frame, making it impossible to flexibly adjust the detection height according to product specifications (such as thickness and volume), which makes it difficult to quickly adapt to diverse products, resulting in decreased detection accuracy or limited equipment applicability. At the same time, as a core component, the metal detector may require maintenance or replacement due to malfunction or sensitivity decay after long-term use. However, the existing structure adopts a fixed installation method, which makes the disassembly process cumbersome, requires tools, and is time-consuming, affecting the continuous operation of the production line.

[0006] This utility model provides the following technical solution: a metal detection and weighing integrated machine, including a metal detection line, a weight detection line, and a rejection line. A mounting frame is fixedly installed on the metal detection line. Slide grooves are provided on both inner side walls of the mounting frame. Sliding blocks are slidably fitted inside the two slide grooves. A mounting block is fixedly installed between the two sliding blocks. A metal detector is detachably installed below the mounting block. A mounting plate is fixedly installed on the outer shell of the metal detector. The lower surface of the mounting block has a mounting groove that matches the mounting plate. A screw is rotatably installed on the surface of the mounting block. A connecting plate is threaded onto the surface of the screw. A row of locking rods is fixedly connected to the surface of the connecting plate. A row of locking grooves that match the locking rods are opened on the surfaces of both the mounting block and the mounting plate. A lifting assembly is provided on the lower surface of the mounting frame. The mounting block is mounted on the lifting assembly.

[0007] Preferred technical solution 1: A limiting rod is fixedly installed on the surface of the mounting block, and a limiting groove is formed on the surface of the connecting plate. The connecting plate is slidably sleeved on the limiting rod through the limiting groove.

[0008] Preferred technical solution 2: The lifting assembly includes a bidirectional lead screw rotatably mounted on both sides of the inner wall of the mounting frame. Two lead screw sleeves are threaded onto the surface of the bidirectional lead screw. The lifting assembly also includes a slide rod fixedly mounted between the two sides of the inner wall of the mounting frame. Two slide sleeves are slidably mounted on the surface of the slide rod. Connecting rods are movably mounted on the lower surfaces of the two slide sleeves and the two lead screw sleeves. All four connecting rods are movably connected to the mounting block.

[0009] Preferred technical solution 3: An electric push rod is fixedly installed on the side of the rejection line, a push plate is fixedly installed on the output end of the electric push rod, and a storage box is fixedly installed on the other side of the rejection line.

[0010] Preferred technical solution four: A control cabinet is provided on one side of the weight detection line.

[0011] Preferred technical solution five: A support frame is provided below the metal detection line, the weight detection line and the rejection line, and each support frame is provided with four legs at the bottom.

[0012] Compared with existing technologies, this utility model provides a metal detection and weighing integrated machine with the following advantages: During use, items are conveyed through a metal detection line, detected by a metal detector, and then conveyed to a weight detection line for weighing. Finally, they flow into a rejection line, where an electric push rod pushes out unqualified items into a storage box for separate storage. Simultaneously, during metal detection, rotating the bidirectional lead screw in either the forward or reverse direction moves two lead screw sleeves in opposite directions, thereby raising or lowering the mounting block and metal detector via a connecting rod. This allows for adjustment of the metal detector height according to different items, making it highly adaptable. When the metal detector is damaged and needs repair or replacement, rotating the screw moves the connecting plate, causing multiple locking rods to disengage from the mounting block and the slots on the mounting plate. The metal detector can then be removed from the mounting block for repair or replacement, which is convenient and quick. This utility model allows for adjustment of the metal detector height according to different items, making it highly adaptable. It also allows for quick installation and removal of the metal detector, facilitating repair or replacement. Attached Figure Description

[0015] Please see Figure 1-3 , Example 1: A metal detection and weighing integrated machine includes a metal detection line 1, a weight detection line 2, and a rejection line 3. A mounting frame 4 is fixedly installed on the metal detection line 1. Slide grooves 5 are provided on both inner side walls of the mounting frame 4. Sliding sliders 6 are slidably fitted inside the two slide grooves 5. A mounting block 7 is fixedly installed between the two sliding sliders 6. A metal detector 8 is detachably installed below the mounting block 7. A mounting plate 9 is fixedly installed on the outer shell of the metal detector 8. The lower surface of the mounting block 7 is provided with a mounting groove 10 that matches the mounting plate 9. A screw 11 is rotatably installed on the surface of the mounting block 7. A connecting plate 12 is threaded onto the surface of the screw 11. A row of locking rods 13 is fixedly connected to the surface of the connecting plate 12. A row of locking grooves 14 that match the locking rods 13 are provided on the surfaces of both the mounting block 7 and the mounting plate 9. A lifting assembly is provided on the lower surface of the mounting frame 4. The mounting block 7 is mounted on the lifting assembly.

[0016] Example 2: The difference between this example and Example 1 is that a limiting rod 15 is fixedly installed on the surface of the mounting block 7, and a limiting groove is opened on the surface of the connecting plate 12. The connecting plate 12 is slidably sleeved on the limiting rod 15 through the limiting groove, which facilitates the restriction of the movement of the connecting plate 12 and makes it easier to install and disassemble the metal detector 8.

[0017] Example 3: The difference between this example and Example 1 is that the lifting assembly includes a bidirectional lead screw 17 rotatably mounted on both sides of the inner wall of the mounting frame 4. Two lead screw sleeves 18 are threaded onto the surface of the bidirectional lead screw 17. The lifting assembly also includes a slide rod 19 fixedly mounted between the two sides of the inner wall of the mounting frame 4. Two slide sleeves 20 are slidably mounted on the surface of the slide rod 19. Connecting rods 21 are movably mounted on the lower surfaces of the two slide sleeves 20 and the two lead screw sleeves 18. All four connecting rods 21 are movably connected to the mounting block 7, which facilitates the adjustment of the height of the metal detector 8.

[0018] Example 4: The difference between this example and Example 1 is that an electric push rod 22 is fixedly installed on the side of the rejection line 3, and a push plate is fixedly installed at the output end of the electric push rod 22. A storage box 23 is fixedly installed on the other side of the rejection line 3 to facilitate the rejection of unqualified items.

[0019] Example 5: The difference between this example and Example 1 is that a control cabinet 24 is provided on one side of the weight detection line 2.

[0020] Example 6: The difference between this example and Example 1 is that a support frame 16 is provided below the metal detection line 1, the weight detection line 2, and the rejection line 3. Each support frame 16 has four feet at its bottom, making the overall structure more stable.

[0021] In summary, the metal detection line 1, weight detection line 2, rejection line 3, and metal detector 8 of this integrated metal detection and weighing machine are all existing technologies, and their control methods and structures are also existing technologies. Therefore, they will not be described in detail in this embodiment. In use, the items are conveyed through the metal detection line 1, detected by the metal detector 8, and then conveyed to the weight detection line 2 for weighing. Finally, they flow into the rejection line 3, where the electric push rod 22 pushes the unqualified items into the storage box 23 for separate storage. At the same time, during metal detection, the two lead screw sleeves 18 can be moved in opposite directions or towards each other by rotating the bidirectional lead screw 17 in either the forward or reverse direction. The connecting rod 21 drives the mounting block 7 and the metal detector 8 to rise or fall, thereby adjusting the height of the metal detector 8 according to different items. It is highly adaptable. When the metal detector 8 is damaged and needs to be repaired or replaced, the connecting plate 12 is moved by rotating the screw 11, thereby causing multiple locking rods 13 to disengage from the locking slots 14 on the mounting block 7 and the mounting plate 9. Then the metal detector 8 can be removed from the mounting block 7 for repair or replacement, which is convenient and quick. In use, the height of the metal detector 8 can be adjusted according to different items, making it highly adaptable. At the same time, the metal detector 8 can be quickly installed and disassembled, facilitating its repair or replacement.
