Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of metal detection equipment, in particular to a split type metal detector suitable for bulk materials and packaged materials. BACKGROUND

[0002] The common metal detection equipment similar to the present application in the market mainly comprises a detection channel, a detection sensor, a control unit, a display operation unit and an alarm device, but in the use process, the detection channel is usually a fixed tubular or channel structure, the materials are conveyed into the detection channel by a conveying belt or artificial way, the detection sensor generally adopts electromagnetic induction principle, and most of them can only detect magnetizable metals, and the detection sensitivity for non-magnetizable metals such as copper and aluminum is low, and even cannot be detected, so it is difficult to meet the detection needs of such impurities in recycled materials.

[0003] To overcome the above-mentioned defects, the existing technology (Chinese patent application with application number CN201120572588.X, application date 2011-12-31) metal detection device can detect paper products containing metal foreign objects, and when passing through the automatic rejection mechanism, the paper products containing metal foreign objects are discharged from the conveyor belt without affecting the operation of other paper products. This type of metal detection device can not only effectively ensure the quality of paper products and avoid product quality problems caused by operator negligence, but also save labor and reduce product processing costs. There is also existing technology (Chinese patent application CN201520018032.4, application date 2015-01-12) of a metal foreign object detection machine with a conveyor belt containing a metal joint, which effectively overcomes the interference of the metal joint on the detector and avoids the incorrect rejection of normally inspected items. And there is existing technology (Chinese patent application CN201610487842.3, application date 2016-06-29) of a conveyor belt tracking device for non-magnetic metal objects in mineral materials, which is controlled by signals from existing metal detectors around the conveyor belt. After the metal detector sends a signal that metal has been detected, it uses a traction electromagnetic... The movement of the iron causes the marker to fall automatically onto the conveyor belt. After adjusting the installation position of this device according to the reaction time of the equipment controlled on site, the marker can accurately indicate the location of metal debris, greatly reducing the scope of manual searching, reducing the downtime of the unit and the labor intensity of workers, improving production efficiency, and bringing high efficiency and convenience to the manual removal of metal parts. When tested in the metal detection and removal process of the port nylon conveyor system, it demonstrated good safety and field application value. Although existing technologies can complete the detection work, some equipment has poor adaptability to materials during operation and cannot simultaneously meet the detection needs of bulk materials such as crushed plastic recycling materials, electronic waste debris and packaging materials such as waste packaging containers. It is also difficult to clean the equipment, and the installation process is relatively complicated and inconvenient to meet the switching of different physical forms.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1-9 The present invention provides a technical solution: a split-type metal detector suitable for bulk materials and packaged materials, which is provided with a conveying component 1 and a support base 2 assembled on the upper surface of the conveying component 1.

[0023] Example 1: As Figures 1-9 The present invention provides the following technical solution: a split-type metal detector suitable for bulk materials and packaged materials, comprising: a detection housing 3 disposed on the upper surface of a support base 2, a detector body 4 assembled on the inner surface of the detection housing 3, a lifting ring 5 installed on the upper surface of the detection housing 3, a lifting component 6 installed on the lower surface of the detector body 4, the lifting component 6 being connected to a positioning component 7 via a limiting lifting mechanism, a locking assembly 15 installed on the outer surface of the detector body 4, the locking assembly 15 being connected to the lifting component 6 via a pressing and engaging mechanism, a cleaning frame 27 connected to the detector body 4 via a reciprocating drive mechanism, and a magnetic base 29 installed on the lower surface of the positioning component 7.

[0024] In use, a support base 2 is assembled on the outer surface of the conveying component 1. The detector body 4, assembled on the support base 2, is connected to the detection housing 3, which controls the stability of the detector body 4 during operation. A lifting ring 5 installed on the upper side of the detector body 4 facilitates lifting operations, adapting to various working environments. A lifting component 6 and a positioning component 7 are assembled on the lower side of the detector body 4, controlling the lifting and lowering of these components. This adapts to the conveying and detection of bulk and packaged materials, improving detection efficiency. Combined with a magnetic base 29, it can be directly connected to different equipment, adapting to different working environments. A ceramic coating is applied to the detection surface of the detector body 4. A nano-alumina ceramic coating, compared to a Teflon coating, offers improved wear resistance, making it suitable for detecting recycled materials containing hard particles. Alternatively, a PEEK coating, using a high-temperature curing PEEK coating, provides excellent acid and alkali resistance, suitable for detecting recycled materials containing acidic or alkaline contaminants, preventing corrosion damage to the coating.

[0025] Example 2: Figures 1-6The technical solution shown, based on Embodiment 1, further discloses the stability of the assembly between the lifting component 6 and the positioning component 7 and the detector body 4, and controls the height adjustment between the lifting component 6 and the positioning component 7, improving the stability of the disassembly and assembly of the detector body 4, preventing detachment, and adapting to the conveying of different bulk and packaged materials. It solves the problems of some equipment having poor material adaptability during operation, being unable to simultaneously meet the detection requirements of bulk materials such as crushed plastic recycling materials, electronic waste debris, and packaged materials such as waste packaging containers, and the difficulty in cleaning the equipment and the complexity of the installation process. Specifically, the detection housing 3 and the detector body 4 form a nested structure, and the detection housing 3 and the lifting ring 5 form a threaded structure. The detector body 4 and the lifting component 6 form a limiting engagement structure, while the lifting component 6 and the positioning component 7 form a lifting structure; Figure 3 and Figure 4 As shown, the limiting lifting mechanism also includes a rotating shaft 8 rotatably connected to the positioning component 7, and a bevel gear set 9 connected to the outer surface of the rotating shaft 8. A horizontal gear in the bevel gear set 9 is connected to a lifting threaded rod 10. Simultaneously, a lifting rod 11 is threadedly connected to the outer surface of the lifting threaded rod 10, and the lifting rod 11 is installed on the lower surface of the lifting component 6. A nested rod 12 is telescopically connected to the outer surface of the lifting rod 11, and the lifting threaded rod 10 is positioned and rotated on the inner surface of the nested rod 12. The nested rod 12 is installed on the upper surface of the positioning component 7, and a telescopic assembly 13 is installed on the outer surface of the positioning component 7. A telescopic rod 14 is telescopically connected to the inner surface of the telescopic assembly 13, and the telescopic rod 14 is installed on the side of the lifting component 6. Figure 3 and Figure 4 As shown, the positioning component 7 forms a rotating structure with the bevel gear set 9 via the rotating shaft 8, and the bevel gear set 9 forms a coaxial rotating structure with the lifting threaded rod 10. Furthermore, the positioning component 7 and the nested rod 12 form an integrated structure, while the nested rod 12 forms a threaded lifting structure with the lifting rod 11 via the lifting threaded rod 10, and the lifting rod 11 forms an integrated structure with the lifting component 6. Figure 3 and Figure 4 As shown, the positioning component 7 is embedded in the outer surface of the telescopic assembly 13, and the telescopic assembly 13 forms a limiting lifting structure with the lifting component 6 through the telescopic rod 14. Furthermore, the telescopic assembly 13 is symmetrically arranged about the middle section of the outer surface of the positioning component 7. Figure 5 and Figure 6As shown, the compression locking mechanism also includes a rotating member 16 rotatably connected to the inner surface of the locking assembly 15, and a connecting rod 17 rotatably connected to the outer surface of the rotating member 16. A moving rod 18 is rotatably connected to the other end of the outer surface of the connecting rod 17, limiting the sliding of the moving rod 18 on the inner surface of the locking assembly 15. A compression spring 20 is elastically connected between the locking assembly 15 and the moving rod 18. A locking member 19 is installed on the outer surface of the moving rod 18, limiting and locking the locking member 19 in the slot 23 opened in the lifting member 6. A positioning post 21 is installed on the lower surface of the locking assembly 15, and a positioning sleeve 22 is nested on the outer surface of the positioning post 21, installing the positioning sleeve 22 on the outer surface of the lifting member 6. Figure 5 and Figure 6 As shown, the locking assembly 15 and the rotating member 16 form a rotating structure, and the rotating member 16 forms a crank-connecting rod structure with the moving rod 18 via the connecting rod 17. The moving rod 18 forms an elastic sliding structure with the locking assembly 15 via the compression spring 20, and the moving rod 18 and the locking member 19 form an integrated structure. Figure 5 and Figure 6 As shown, the moving rod 18 forms a limiting engagement structure with the lifting component 6 through the locking component 19 and the slot 23, and the locking component 15 and the positioning post 21 form an integrated structure, and the locking component 15 forms an embedded structure with the positioning sleeve 22 through the positioning post 21.

[0026] When the detector body 4 is working at a higher position on the conveying assembly 1, the detector body 4 is assembled on the conveying assembly 1. The motor assembled on the outside of the positioning component 7 drives the bevel gear set 9 assembled on the rotating shaft 8 to rotate. This allows the lifting threaded rod 10, which is assembled with the horizontal gear in the bevel gear set 9, to be positioned and rotated on the inner surface of the nested rod 12. The lifting rod 11 is limited to rising and falling on the inner surface of the nested rod 12 by adjusting the thread of the lifting threaded rod 10. This controls the lifting component 6 to rise or fall on the outer surface of the positioning component 7, thereby controlling the height of the detector body 4. During the lifting and lowering adjustment process, the telescopic component 13 assembled through the positioning component 7 and the telescopic rod 14 assembled through the lifting component 6 are limited to extend and retract, improving the stability of the lifting and lowering control between the lifting component 6 and the positioning component 7, and also ensuring that the detector body 4 can be disassembled and replaced as needed. When replacing the detector body 4, the rotating part 16 inside the locking assembly 15 is rotated by starting the detector body 4. This rotates the connecting rod 17, which in turn rotates the rotating part 16. The moving rod 18 is controlled to slide and extend within the locking assembly 15, and the compression spring 20 between the locking assembly 15 and the moving rod 18 is controlled to retract. This causes the clip 19 installed on the moving rod 18 to disengage from the slot 23, allowing the detector body 4 to be removed and replaced. The positioning post 21 of the new detector body 4 is then nested in the positioning sleeve 22, improving the stability of the detector body 4 assembly. The clip 19 controlled by the locking assembly 15 is stably nested in the slot 23 opened in the lifting part 6. By releasing the handle controlling the rotating part 16, the clip 19 is engaged in the slot 23 by the elasticity of the compression spring 20, improving the engagement stability.

[0027] Example 3: Figure 7 , Figure 8 and Figure 9 The technical solution shown, based on Embodiment 2, further discloses the cleaning stability of the detector body 4 and its ability to be assembled with the magnetic base 29 on different devices, improving the convenience of adjusting the working position and solving the problem of inconvenience in switching physical forms according to different working environments. The specific details are as follows: The reciprocating drive mechanism also includes a controller 24 mounted on the outer surface of the detector body 4 via a lifting member 6, and a protective shell 25 nested on the outer surface of the controller 24. A reciprocating threaded rod 26 rotates on the lower surface of the detector body 4, and a cleaning frame 27 is slidably connected to the outer surface of the reciprocating threaded rod 26. A cleaning rod 28 is mounted on the outer surface of the cleaning frame 27, and the lifting member 6 is assembled with the magnetic base 29 via a positioning member 7; Figure 7 , Figure 8 and Figure 9As shown, the detector body 4 is integrated with the controller 24 via the lifting component 6, and the controller 24 and the protective shell 25 form a nested structure. The detector body 4 is also integrated with the cleaning frame 27 via the reciprocating threaded rod 26, and the cleaning frame 27 and the cleaning rod 28 form an integrated structure. The lifting component 6 is integrated with the magnetic base 29 via the positioning component 7.

[0028] During use, the controller 24, assembled by the lifting component 6, is nested with the protective shell 25 to improve the stability of the controller 24 assembly. After the detector body 4 has been working for a long time, the reciprocating threaded rod 26 driven by the motor assembled on the lower side of the detector body 4 will rotate. This will control the cleaning rod 28 installed on the cleaning frame 27 connected to the reciprocating threaded rod 26 to contact the lower side of the detector body 4, thereby cleaning the impurities of the detector body 4. This will cooperate with the ultrasonic transducer installed on the outside of the detection channel of the detector body 4. The magnetic base 29 can be assembled during the assembly of the detector body 4 to control the detector body 4 to adapt to different equipment.

[0029] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0030] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
