Description

Technical Field

[0001] This disclosure relates to the field of material sorting, specifically to a switch assembly and a sorting machine. Background Technology

[0002] In various types of equipment, switches, as key components controlling the on / off state of external parts or circuits, directly affect the safety and reliability of the equipment. However, switches are often mistakenly triggered due to improperly closed equipment doors, potentially causing equipment shutdowns, or even situations where the door is slightly ajar without triggering the switch. This not only reduces equipment reliability and stability, impacting production efficiency, but also poses significant safety hazards. For example, in the sorting of ores, coal, or plastics, X-rays can be used to identify the ore. To prevent X-ray leakage when the door is open, an X-ray machine power disconnection mechanism is installed, disconnecting the power supply when the door is detected as open. However, the opening and closing of the door may be uncontrolled, leading to false detections and accidental opening of the door, resulting in low safety and reduced production efficiency. Utility Model Content

[0003] To overcome the problems existing in the related technology, an exemplary embodiment of this disclosure provides a first aspect of a switch assembly, wherein the switch assembly includes: a micro switch for being disposed on a fixed plate, the micro switch including a retractable mechanical probe, the mechanical probe being able to trigger a corresponding signal in an extended state and / or a retracted state; a handle for being rotatably disposed on a door panel, wherein the door panel is movable relative to the fixed plate; a trigger member fixedly disposed on the handle and capable of rotating synchronously with the handle, the trigger member having an abutting arc surface; wherein, when the handle is rotated to a first position, the abutting arc surface pushes the mechanical probe to the retracted state; when the handle is rotated to a second position, the abutting arc surface moves away from the mechanical probe to allow the mechanical probe to extend to the extended state.

[0004] In some embodiments, the handle is located in the first position, and the mechanical probe abuts against a first region of the abutting arc surface; the handle rotates from the first position to the second position, and the mechanical probe disengages from the abutting arc surface from its first end; wherein the radius of the first end of the abutting arc surface is smaller than the radius of the first region.

[0005] In some embodiments, the first region is formed with a plane for abutting the mechanical probe when the handle is in the first position; and / or, the abutting arc surface is formed with a protrusion, the protrusion being formed circumferentially between the first region and the first end, the radius of the protrusion being greater than the radius of the first region.

[0006] In some embodiments, the end of the mechanical probe is provided with a roller for rolling on the abutment arc surface.

[0007] In some embodiments, the switch assembly further includes a limiting member disposed on the fixing plate, including a limiting portion perpendicular to the rotation axis of the handle; when the handle is rotated to the first position, the limiting portion is located outside the axis of the trigger member to limit the trigger member.

[0008] In some embodiments, the limiting member is disposed on one side of the micro switch, and when the handle is in the second position, the trigger member is located inside the axial direction of the limiting portion.

[0009] In some embodiments, the switch assembly further includes: a first base, which is connected to the handle for hinged to the door panel; and a second base, which is spaced apart from the first base and fixedly connected to the limiting member for fixing the limiting member to the fixing plate.

[0010] In some embodiments, the curvature of the abutting arc surface is generally 60-80 degrees.

[0011] In some embodiments, the rotation angle of the handle is 60-100 degrees.

[0012] Secondly, this disclosure also provides a sorting machine for material sorting, comprising: a conveying mechanism for conveying materials; an identification mechanism including an X-ray source for identifying the materials conveyed by the conveying mechanism; a housing disposed outside the identification mechanism, including a fixed plate and a door panel movable relative to the fixed plate; a switch assembly as described in the first aspect, wherein the handle is disposed on the door panel and the micro switch is disposed on the fixed plate; and a sorting mechanism for sorting the materials according to the identification result of the identification mechanism.

[0013] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure.

[0014] This disclosure provides a switch assembly and a sorting machine. The switch assembly includes a micro switch, a handle, and a trigger. The abutment arc surface on the trigger cooperates with a mechanical probe to control the triggering of the micro switch. When the handle is rotated to the first position, the abutment arc surface pushes the mechanical probe to a retracted state, ensuring the switch signal is triggered. When the handle is rotated to the second position, the abutment arc surface separates from the mechanical probe, allowing the mechanical probe to extend and disconnect the signal, effectively solving the trigger delay problem of traditional switches. The switch assembly independently integrates the micro switch, handle, and trigger, forming an interlock and effectively linking them. Furthermore, the switch assembly is more adaptable to different installation layouts, avoiding false triggering caused by a poorly closed door when built-in, and delayed triggering when external, thus enhancing the reliability of the switch assembly in various application scenarios. The switch assembly achieves strong linkage functionality through a simple mechanical structure, reducing production and maintenance costs, improving the overall safety and user experience of the equipment, and enhancing the reliability and stability of the equipment. In the first position, the handle can be coupled to the door panel, and the door panel can be in a locked state. This ensures that the door panel remains closed even when the micro switch is closed, thus ensuring stable operation of the equipment, further improving the reliability and efficiency of the equipment.

[0025] In some related technologies, the microswitch can be installed inside the door panel. If the door is not closed tightly, the microswitch may be accidentally triggered, leading to unnecessary activation. In other related technologies, the microswitch is independently installed on the outside of the door panel. Due to the presence of the microswitch, even if the door is slightly ajar, the microswitch may not be triggered. The lack of independent interlocking between the microswitch and the door handle, and the absence of an effective correlation between the microswitch's opening and closing, the handle's rotation, and the door's opening and closing, may cause the equipment to stop or open accidentally.

[0026] To overcome the problems existing in related technologies, exemplary embodiments of this disclosure provide a switching component 100, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the switch assembly 100 may include: a micro switch 110, a handle 120, and a trigger 130.

[0027] Micro switch 110, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the micro switch 110, which can be mounted on a fixed plate, may include a retractable mechanical probe 111. The mechanical probe 111 can trigger a corresponding signal when it is extended or retracted. The micro switch 110 can be fixed to the fixed plate by bolts, welding, or other methods. The mechanical probe 111 can be provided at the end of the micro switch 110. The mechanical probe 111 can be made of a high-hardness alloy and can extend and retract. This extension and retraction is achieved by the extension and retraction of a spring inside the micro switch 110. The extension and retraction stroke can be 1mm-30mm. When the trigger 130 acts on the mechanical probe 111, the mechanical probe 111 undergoes an extension and retraction displacement. When the mechanical probe 111 is in the extended state, there is no external force acting on it. The mechanical probe 111 extends to its maximum position, and the micro switch 110 outputs an open signal. When the mechanical probe 111 is in the retracted state, the trigger 130 applies an external force, causing the mechanical probe 111 to retract, and the micro switch 110 outputs a closed signal.

[0028] Handle 120, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, a handle 120 is rotatably mounted on a door panel, allowing the door panel to move relative to a fixed plate. The handle 120 can be made of high-strength aluminum alloy and can be mounted on the door panel via a pivot, enabling rotation. The door panel and fixed plate can be spaced apart, either vertically or horizontally. The fixed plate can be a wall panel or a movable plate. The fixed plate can be installed indoors or on large equipment, such as a sorting machine. The door panel can move relative to the fixed plate, opening by sliding or rotating. When an operator applies force to turn the handle 120, a trigger 130 mounted on the side of the handle 120 rotates synchronously with it.

[0029] Trigger 130, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, it can be fixedly installed on the handle 120 and can rotate synchronously with the handle 120; the trigger 130 forms an abutting arc surface 131; wherein, as Figure 5 , Figure 6 As shown, the handle 120 is in the first position. When the handle 120 is rotated to the first position, it abuts against the arc surface 131 and pushes the mechanical probe 111 to the retracted state; as shown... Figure 2 As shown, the handle 120 is in the second position. When the handle 120 is rotated to the second position, the abutting arc surface 131 moves away from the mechanical probe 111, causing the mechanical probe 111 to extend to its extended state. The trigger 130 can be fan-shaped and can be fitted with the handle 120 through a positioning hole. It can be fixed with screws or integrally formed to ensure no angular deviation when rotating synchronously with the handle 120. The abutting arc surface 131 of the trigger 130 can abut against the mechanical probe 111. When the door needs to be closed, the handle 120 rotates to the first position, such as... Figure 1 As shown, the rotation is clockwise. When the handle 120 is rotated, the trigger 130 rotates synchronously, gradually approaching the mechanical probe 111 from the abutting arc surface 131. Upon contact, the probe retracts, at which point the internal contacts of the microswitch 110 close, outputting a device start signal. When the door needs to be opened, the handle 120 rotates in the opposite direction, causing the abutting arc surface 131 to gradually disengage from the mechanical probe 111. The mechanical probe 111 then retracts under the action of an internal spring, and the microswitch 110 returns to its initial state.

[0030] The trigger 130 can be adjusted relative to the handle 120. A sliding groove can be provided on the inner side of the handle 120. The trigger 130 can slide up and down relative to the pivot of the handle 120. The trigger 130 can extend or retract relative to the handle 120. When the handle 120 is rotated to the first position, the trigger 130 can extend to compress the mechanical probe 111. When the handle 120 is rotated to the second position, the trigger 130 can retract, increasing the flexibility of the switch assembly 100.

[0031] In some embodiments, in material sorting machines for ores, plastics, coal, etc., the ore content is typically identified by emitting X-rays. The microswitch 110 can directly control the power supply of the X-ray machine. When the door is closed, the trigger 130 pushes the mechanical probe 111 of the microswitch 110, turning on the X-ray machine. When the door is opened, the mechanical probe 111 of the microswitch 110 extends, turning off the power supply to the X-ray machine. The microswitch 110 can also be coupled to other control power supplies or connected to other mechanical components.

[0032] In this embodiment, the engagement of the abutment arc surface 131 on the trigger 130 with the mechanical probe 111 controls the triggering of the micro switch 110. When the handle 120 is rotated to the first position, the abutment arc surface 131 pushes the mechanical probe 111 to a retracted state, ensuring the triggering of the switch signal. When the handle 120 is rotated to the second position, the abutment arc surface 131 can separate from the mechanical probe 111, allowing the mechanical probe to extend and disconnect the signal, effectively solving the trigger delay problem. The switch assembly 100 independently links the micro switch 110, handle 120, and trigger 130, forming an interlock and effectively associating them. Furthermore, the switch assembly 100 is more adaptable to different installation layouts, avoiding false triggering caused by a door not closing properly when built-in, and untimely triggering when external, thus enhancing the reliability of the switch assembly 100 in different application scenarios. The switch assembly 100 can achieve complex linkage functions through a simple mechanical structure, reducing production and maintenance costs, improving the overall safety and user experience of the equipment, and enhancing its reliability and stability. In the first position, the handle 120 can be coupled to the door panel, which can be in a locked state. This ensures that the door panel remains closed even when the micro switch 110 is closed, guaranteeing stable operation of the equipment and further improving its reliability and efficiency.

[0033] In some embodiments, such as Figure 3 , Figure 4 , Figure 5 , Figure 6As shown, when the handle 120 is in the first position, the mechanical probe 111 can abut against the first area of ​​the abutment surface 131. When the handle 120 rotates from the first position to the second position, the mechanical probe 111 disengages from the first end of the abutment surface 131. The radius of the first end of the abutment surface 131 can be smaller than the radius of the first area. The first area can be a portion of the abutment surface 131 when the mechanical probe 111 abuts against it, at which point the mechanical probe 111 is in a fully retracted state. The trigger 130 can be fan-shaped, so that when the handle 120 is in the first position, the mechanical probe 111 can completely abut against the first area of ​​the abutment surface 131. The radius of the first end of the abutment surface 131 can be smaller than the radius of the first area. When the handle 120 rotates from the first position to the second position, the mechanical probe 111 begins to slide along the abutment surface 131 and gradually moves towards the first end. As the mechanical probe 111 approaches the first end, its radius decreases, allowing it to extend directly and disengage from the abutment surface 131. When the handle 120 rotates from the second position to the first position, the mechanical probe 111 begins to slide along the first end and gradually moves towards the abutment surface 131. As the mechanical probe 111 approaches the first region, its radius increases, causing it to retract directly and completely press against the abutment surface 131. The radius difference between the first end and the first region matches the extension amount of the mechanical probe 111; when the mechanical probe 111 reaches its maximum extension, it can completely disengage from the first end. The edge of the first end can be designed with a 2mm-3mm wide guide plane. When the handle 120 begins to rotate, the inclined plane can guide the mechanical probe 111 to smoothly transition to and from the abutment surface 131, or smoothly disengage from it.

[0034] In this embodiment, by making the radius of the first region larger than the radius of the first end of the abutting arc surface 131, the mechanical probe 111 can be fully abutted against the abutting arc surface 131 through the radius difference, so as to achieve a smooth transition. This greatly improves the response speed and service life of the micro switch 110, and can reduce the maintenance cost and failure rate of the equipment.

[0035] In some embodiments, the first region may be formed with a plane for abutting the mechanical probe 111 when the handle 120 is in the first position. In the structural configuration of the trigger 130, the first region may be provided with a planar structure to provide stable support for the switch assembly 100. When the handle 120 is in the first position, the mechanical probe 111 can abut against the plane. Since the radii of the first region and the first end are different, under the action of the spring force and other forces inside the micro switch 110, the mechanical probe 111 is driven to slide towards the arc surface with the smaller radius, thereby causing the trigger 130 to slide, which in turn causes the handle 120 to rotate, causing the micro switch 110 to disengage from the abutting arc surface 131, resulting in unstable contact between the mechanical probe 111 and the abutting arc surface 131. Therefore, the plane set in the first area can achieve a stable contact with the mechanical probe 111. Combined with the spring preload inside the micro switch 110, a stable structure is formed. During the operation of the equipment, even if it is subjected to external interference such as vibration and impact, the mechanical probe 111 is not easy to be displaced, ensuring that the micro switch 110 continuously outputs a reliable trigger signal.

[0036] In some embodiments, the abutting arc surface 131 may have a protrusion formed therein, which is formed circumferentially between the first region and the first end, and the radius of the protrusion may be larger than the radius of the first region. In the structural configuration of the trigger 130, the protrusion may also be disposed between the first region and the first end. When the handle 120 moves to the first position, if the radii of the first region and the first end are not the same, the spring force or other forces inside the micro switch 110 can drive the mechanical probe 111 to slide towards the arc surface with the smaller radius, causing the trigger 130 to slide and the handle 120 to rotate accordingly, causing the micro switch 110 to disengage from the arc surface 131, making the contact between the two unstable. The protrusion can make the mechanical probe 111 and the abutting arc surface 131 form a stable structure, preventing the handle 120 from sliding. During the operation of the equipment, even if subjected to external interference such as vibration and impact, the mechanical probe 111 is not easily displaced, ensuring that the micro switch 110 continuously outputs a reliable trigger signal.

[0037] In this embodiment, the first region may be formed with a plane or with a protrusion between the first region and the first end, both of which can prevent the mechanical probe 111 from shifting when in contact, ensuring the stability of the mechanical probe contact, extending the service life of the mechanical probe 111 and the trigger 130, reducing the frequency of equipment maintenance due to wear, improving the reliability and stability of the switch assembly 100, increasing production efficiency, and reducing manufacturing costs.

[0038] In some embodiments, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, a roller 112 can be provided at the end of the mechanical probe 111, and the roller 112 can be used to roll on the abutting arc surface 131. The roller 112 can be cylindrical and can roll against the abutting arc surface 131. The central axis of the circular surface of one end plane or both end planes of the roller 112 can be fixedly connected to the lower end of the mechanical probe 111, and the fixed connection method can be welding or the like. The roller 112 can also be spherical and fixedly provided at the lower end of the mechanical probe, rolling against the abutting arc surface 131. In this embodiment, by rolling the end of the mechanical probe 111 against the abutting arc surface 131 when the door panel is open or closed, relative movement can be generated. At the same time, it is necessary to keep the lower end of the mechanical probe 111 in a retracted state. By setting the roller 112, it can roll on the abutting arc surface 131. Compared with the mechanical probe directly contacting the abutting arc surface 131, wear between components can be reduced, the service life of components can be extended, and maintenance costs can be reduced. The setting of the roller 112 can make the movement smooth and prevent jamming.

[0039] In some embodiments, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, the switch assembly 100 may further include a limiting member 140, which is disposed on the fixed plate and includes a limiting portion perpendicular to the rotation axis of the handle 120. When the handle 120 is rotated to the first position, the limiting portion is located outside the axial direction of the trigger member 130 to limit the trigger member 130. The limiting member 140 may be made entirely of high-strength stainless steel and may be L-shaped and perpendicular to the rotation axis of the handle 120. The thickness of the limiting member 140 may be 2mm-10mm, and the width may be 5mm-20mm. This not only provides sufficient support strength but also avoids interference with the rotation of the trigger member 130. The limiting member 140 can be fixed to the fixing plate by bolts. The limiting member 140 may include a limiting part perpendicular to the axial direction of the handle 120. When the handle 120 is rotated to the first position, the limiting part may be located on the outer side of the axial direction of the trigger member 130. The direction away from the fixing plate is the outer side. The limiting part can prevent the trigger member 130 from moving in the direction away from the fixing plate, thereby ensuring that the mechanical probe 111 is stably set on the abutting arc surface 131 while the door panel is closed.

[0040] In this embodiment, the limiting member 140 can prevent the trigger member 130 from shifting away from the fixed plate when the handle 120 is rotated to the first position. This allows the mechanical probe 111 to be stably positioned on the abutting arc surface 131 while keeping the door panel closed, thus improving the reliability and stability of the switch assembly 100 and preventing the device from stopping accidentally due to the door panel being opened.

[0041] In some embodiments, the limiting member 140 may be disposed on one side of the micro switch 110, and when the handle 120 is in the second position, the trigger member 130 is located axially inside the limiting portion. The limiting member 140 may be disposed on the left or right side of the micro switch 110, and the abutting arc surface 131 of the limiting member 140 may make abutting contact with the mechanical probe 111 of the micro switch 110. When the handle 120 is in the second position, such as Figure 2 As shown, when the mechanical probe 111 extends out and does not contact the abutting arc surface 131, the trigger 130 is still located inside the limiting part, and the limiting part still plays a certain limiting role on the trigger 130. When the trigger 130 continues to rotate until the limiting part no longer plays a limiting role on the trigger 130, the door panel opens.

[0042] like Figure 6 , Figure 5 As shown, when the mechanical probe 111 of the microswitch 110 is compressed, the microswitch 110 closes and is triggered; this is the initial state, the first position. The handle 120 then moves from... Figure 6 , Figure 5 Rotate the position counterclockwise to Figure 4 , Figure 3 In this state, the mechanical probe 111 of the microswitch 110 extends first, causing the handle 120 to rotate to the second position, such as... Figure 2 As shown, at this time, the trigger 130 is still inside the limit member 140, the door panel has not yet been opened, and the handle 120 continues to rotate counterclockwise until... Figure 1 When in the state, the trigger 130 is completely disengaged from the limiter 140, and the door panel opens.

[0043] like Figure 1 As shown, in the initial state, the door panel is open. When the door panel needs to be closed, the handle 120 needs to be rotated clockwise to the limit member 140, as follows. Figure 2 As shown, close the door panel tightly, then continue rotating it clockwise, as... Figure 3 , Figure 4 As shown, Figure 4 for Figure 3 After rotating clockwise to the next position, rotate clockwise to... Figure 5 , Figure 6 As shown, Figure 6 for Figure 5Continuing to rotate clockwise to the next position, the handle 120 is in the first position. The mechanical probe 111 of the micro switch 110 is compressed, and the micro switch 110 is closed and triggered. The three have a certain linkage relationship and form an effective connection.

[0044] In this embodiment, when the handle 120 is in the second position, the trigger 130 is still inside the axial direction of the limiting part, which has a certain limiting effect on the trigger 130. As the handle 120 continues to rotate, the door panel opens. The three are independent of each other and form an interlock, effectively linking the micro switch 110, the handle 120 and the closing of the door panel. This solves the problem of the micro switch 110 being falsely triggered due to the door panel not closing tightly, causing the equipment to stop, or the door panel being open but the micro switch 110 still not being triggered.

[0045] In some embodiments, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, the switch assembly 100 may further include: a first base 150 and a second base 160.

[0046] The first base 150 can be connected to the handle 120 to hinge the handle 120 to the door panel. Both the first base 150 and the second base 160 can be plate-like structures. The first base 150 may have handle mounting holes to mount the handle 120 to the door panel, which can be done by bolting or welding. By hinged to the door panel, the handle 120 can rotate, allowing the trigger 130 to rotate synchronously with the handle 120. The second base 160 can be spaced apart from the first base 150 and can be fixedly connected to the limiting member 140 to fix the limiting member 140 to the fixing plate. The second base 160 and the first base 150 can be spaced apart, either vertically or horizontally. The second base 160 may have limiting member mounting holes to fix the limiting member 140 to the fixing plate, which can be done by bolting or welding. In this embodiment, a first base 150 and a second base 160 are provided, which can respectively hinge the handle 120 to the door panel and fix the limiting member 140 to the fixing plate. This can realize the cooperative setting of the handle 120 and the limiting member 140, provide a stable foundation for the switch assembly 100, improve the overall stability and reliability of the assembly, and realize reliable cooperation between the components.

[0047] In some embodiments, the overall curvature of the abutment surface 131 is 60-80 degrees. The trigger 130 can be fan-shaped. The overall curvature of the abutment surface 131 should not be too small. If the curvature is too small, there may be no limiting element 140 to limit the contact when the trigger 130 contacts the mechanical probe 111, resulting in unstable contact and the micro switch 110 may disconnect at any time. The overall curvature of the abutment surface 131 should also not be too large. If the curvature is too large, the door panel may remain closed when the trigger 130 contacts the mechanical probe 111, and the trigger 130 and mechanical probe 111 will remain in contact as the handle 120 rotates, preventing the door panel from opening and rendering the rotation of the handle 120 ineffective. Therefore, the overall curvature of the abutment surface 131 needs to be set to a suitable angle, such as 60-80 degrees. The arc angle can be 60 degrees, 75 degrees, or 80 degrees. This not only allows the trigger element 130 to be limited by the limiting element 140 when it comes into contact with the mechanical probe 111, ensuring the stability of the micro switch 110's triggering, but also allows the mechanical probe 111 to retract quickly and the door to open promptly when the door needs to be opened, ensuring the overall flexibility of the switch assembly 100. Furthermore, the first area, where the mechanical probe 111 fully contacts the abutting arc surface 131, can be less than 60-80 degrees, slightly smaller than the overall arc angle of the abutting arc surface 131. This allows for a reserved area for the mechanical probe 111 to slide against the abutting arc surface 131, ensuring smooth contact and disengagement between them.

[0048] In some embodiments, the rotation angle of the handle 120 can be 60-100 degrees. The rotation angle of the handle 120 should not be too small. If the rotation angle is too small, when the door panel needs to be closed and the micro switch 110 needs to be triggered, the door panel is already closed, but the trigger 130 cannot trigger the micro switch 110 in time, or it may result in the trigger 130 being able to trigger the micro switch 110, but the door panel will open. The rotation angle of the handle 120 should also not be too large. If the rotation angle is too large, the rotation of the handle 120 cannot trigger the micro switch 110 and close the door panel. The rotation angle of the handle 120 can be 60 degrees, 80 degrees, or 100 degrees. A suitable rotation angle allows the handle 120 to open the door panel in its normal state, and to close the door panel by rotating it a certain angle, and to trigger the micro switch 110 by continuing to rotate it a certain angle; or, in the initial state, the micro switch 110 is triggered, the handle 120 rotates a certain angle to disconnect the micro switch 110, and to open the door panel by continuing to rotate it a certain angle. In this embodiment of the present disclosure, by rotating the handle 120 at a suitable angle, it is possible to effectively achieve the following: when the micro switch 110 is open, the door panel is in a closed state; when the door panel is in an open state, the micro switch 110 is in a closed state. This method is highly efficient, easy to implement, and easy to operate.

[0049] Based on the same inventive concept, an exemplary embodiment of this disclosure also provides a sorting machine that can sort materials such as ores, plastics, and coal, including: a conveying mechanism, an identification mechanism, a housing, a switching mechanism 100 as in any of the foregoing embodiments, and a sorting mechanism.

[0050] A conveyor mechanism is used to transport materials. Conveyor mechanisms can be belts, conveyor belts, etc. Materials can be placed on the conveyor mechanism and transported to the identification mechanism.

[0051] Identification mechanisms, including X-ray sources, can be used to identify materials conveyed by a conveying mechanism.

[0052] The housing, which can be located outside the identification mechanism, includes a fixed plate and a door panel that can move relative to the fixed plate. The fixed plate and the door panel can be spaced apart, either vertically or horizontally.

[0053] Switch assembly 100, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6As shown, the handle 120 can be mounted on the door panel, and the micro switch 110 can be mounted on the fixed plate. Furthermore, the engagement of the abutment arc surface 131 on the trigger element 130 of the switch assembly 100 with the mechanical probe 111 controls the triggering of the micro switch 110. When the handle 120 is rotated to the first position, the abutment arc surface 131 pushes the mechanical probe 111 to the retracted state, ensuring the switch signal is triggered. When the handle 120 is rotated to the second position, the abutment arc surface 131 can separate from the mechanical probe 111, allowing the mechanical probe to extend and disconnect the signal, effectively solving the trigger delay problem of traditional switches. The switch assembly 100 independently links the micro switch 110, handle 120, and trigger element 130, forming an interlock and effectively associating them. Furthermore, the switch assembly 100 is more adaptable to different installation layouts, avoiding false triggering caused by the door not closing properly when built-in, and delayed triggering when external, thus enhancing the reliability of the switch assembly 100 in different application scenarios. The switch assembly 100 can achieve complex linkage functions through a simple mechanical structure, reducing production and maintenance costs, improving the overall safety and user experience of the equipment, and enhancing the reliability and stability of the equipment.

[0054] The sorting mechanism is used to sort materials based on the identification results of the identification mechanism. The sorting mechanism can be set downstream of the conveying mechanism. The sorting mechanism can separate materials according to their categories, thus separating different categories of materials from each other.

[0055] The sorting machine of this embodiment can transport materials via a conveying mechanism, facilitating identification and classification by the identification mechanism. Based on the identification mechanism, the materials transported by the conveying mechanism can be identified and classified using an X-ray machine. Finally, different types of materials are sorted according to the sorting mechanism, enabling accurate and rapid classification and sorting of the materials to be tested, with high identification and sorting accuracy. The engagement of the abutting arc surface 131 on the trigger element 130 of the switch assembly 100 with the mechanical probe 111 controls the triggering of the micro switch 110. When the handle 120 is rotated to the first position, the abutting arc surface 131 can push the mechanical probe 111 to the retracted state, ensuring the triggering of the switch signal. When the handle 120 is rotated to the second position, the abutting arc surface 131 can separate from the mechanical probe 111, allowing the mechanical probe to extend and disconnect the signal, effectively solving the triggering delay problem of traditional switches. Furthermore, the switch assembly 100 is more adaptable to different installation layouts, avoiding false triggering caused by the door not closing properly when built-in, and delayed triggering when external, thus enhancing the reliability of the switch assembly 100 in different application scenarios. The switch assembly 100 can achieve complex linkage functions through a simple mechanical structure, improving the reliability and stability of the equipment, reducing production and maintenance costs, and improving the overall safety and user experience of the equipment.

[0056] In some embodiments, the fixing plate can be spaced vertically from the door panel. For example... Figure 7 As shown, a second micro switch 210 can be additionally installed on the fixed plate, and a support plate 220 is installed on the door panel. The support plate 220 has a horizontally extending top surface and can be fixedly installed on the door panel. The support plate 220 can be made of a material with high strength and hardness, such as sheet metal. The top surface of the support plate 220 can extend horizontally, and one end of the top surface can be fixedly installed on the door panel using bolt connection or similar methods. The top surface can be positioned close to the fixed plate. The second micro switch 210 can be vertically installed on the fixed plate and coupled to the power supply of the X-ray machine. The mechanical probe of the second micro switch 210 can extend vertically downwards and can retract and extend vertically. In the closed state, the mechanical probe can abut against the top surface and retract, and the second micro switch 210 can turn on the power supply of the X-ray machine. In the open state, the mechanical probe can detach from the top surface and extend, and the second micro switch 210 can turn off the power supply of the X-ray machine. The second microswitch 210 can be vertically mounted on the fixed plate and positioned close to the door panel, allowing its mechanical probe to extend vertically to abut against the top surface of the support plate 220. The second microswitch 210 can be fixedly mounted on the fixed plate, using methods such as bolt connection. The second microswitch 210 can be coupled to the X-ray power supply. This coupling can be a direct electrical connection or a connection to a control device. The control device can control the on / off state of the X-ray machine based on the microswitch's on / off state. When the mechanical probe of the second microswitch 210 retracts upwards, the X-ray power supply is turned on; when the mechanical probe extends downwards, the X-ray power supply is turned off. When the door panel is closed, the mechanical probe of the second micro switch 210 can abut against the top surface of the support plate 220 and be in a retracted state. At this time, the second micro switch 210 can directly turn on the power supply of the X-ray machine, or it can turn on the power supply of the X-ray machine by connecting the control device. When the door panel is open, the mechanical probe of the second micro switch 210 can detach from the top surface of the support plate 220 and be in an extended state. At this time, the second micro switch 210 can directly turn off the power supply of the X-ray machine, or it can turn off the power supply of the X-ray machine by disconnecting the control device.

[0057] In this embodiment, by providing another second micro switch 210, it can cooperate with the micro switch 110 of the switch assembly 100. When the door panel is open, both the second micro switch 210 and the micro switch 110 are disconnected. When the door panel is closed, both the second micro switch 210 and the micro switch 110 are triggered. This allows for efficient control of the power supply or control module, as well as the on / off operation of mechanical components. It is highly efficient and easy to coordinate.
