Description

Technical Field

[0001] The present application relates to the technical field of material separation, and in particular to a modular sorting actuator and an intelligent dry separation machine. Background Art

[0002] The intelligent dry separation machine is one of the commonly used ore dressing equipment. The intelligent dry separation machine is a device that spreads the ore flat, uses a ray recognition system to identify the ore, and then separates the material through a blowing device.

[0003] In the prior art, the intelligent dry separation machine mainly consists of a feeding system, an irradiation and detection system, a signal processing system, a separation execution system, etc. Among them, the blowing device in the separation execution system has a great influence on the sorting performance of the dry separation equipment. The smoothness of the blowing path directly affects the blowing sorting effect and stability of the dry separation machine. However, due to factors such as high adhesiveness of the sorted material, unreasonable design of the blowing path, and insufficient blowing pressure, the blowing path of the current dry separation equipment is often blocked, resulting in damage to the solenoid valve and inability to work continuously and stably, seriously affecting the blowing sorting effect and requiring frequent and timely maintenance. However, the existing blowing device is bulky, not convenient for installation and maintenance, and has poor versatility between equipment of different specifications, increasing the difficulty of maintenance. In addition, the blowing device consumes too much air, and huge usage costs are required during the operation of the equipment.

[0004] Therefore, there is an urgent need for a new type of modular sorting actuator and intelligent dry separation machine that is structurally compact, convenient for positioning and installation, and can be used alone or in multiple groups spliced together. Summary of the Invention

[0018] Further, splicing interfaces are respectively arranged on two end faces of the camshaft in the camshaft assembly, and two adjacent camshaft assemblies are coaxially connected through the camshaft.

[0019] Further, the housing body includes an upper cover, a base, a partition board, a guide plate, and a gasket. The upper cover is connected above the base and seals the connection through the gasket to jointly form a relatively sealed chamber, and lubricating grease is contained in the chamber;

[0020] The number of the partition plates is multiple, and the multiple partition plates are arranged at intervals along the Y direction in the base, and the partition plates are used for supporting the camshaft;

[0021] The guide plate is connected to a side plate on the side of the upper cover, and the lower end of the tappet assembly passes through the guide plate.

[0022] Further, the tappet assembly includes a tappet, a return spring, and a mounting seat. One end of the tappet passes through the mounting seat, and a ring-shaped boss is arranged in the middle of the other end. The return spring is sleeved between the mounting seat and the ring-shaped boss, and the mounting seat is connected to the outer housing to support the tappet.

[0023] Further, the push plate assembly includes a push plate, a pressing plate, and a wear-resistant plate. One end of the bottom of the push plate is connected to the tappet assembly, and the other end is hinged to a column on the top of the outer housing. One end of the wear-resistant plate is connected in cooperation with the hinged end of the push plate and is pressed by the pressing plate.

[0024] Further, a position sensor is further included, and the position sensor is arranged corresponding to the camshaft and is used for measuring the rotation angle of the camshaft or the linear displacement of the semi-unusual cam.

[0025] Further, the number of the cam drive modules is at least two, and the at least two cam drive modules are arranged along the X direction, and the camshafts of the power devices of two adjacent cam drive modules are coaxially connected to jointly form a modular cam drive module combination, and the power device and the position sensor are respectively arranged at both ends of the modular cam drive module combination.

[0026] The present application further provides an intelligent dry separator, on which the modular sorting execution mechanism as described above is arranged.

[0027] Further, a feeding mechanism is further included, which is used for feeding the material to be sorted into the feeding mechanism;

[0051] Hereinafter, this application will be further described based on preferred implementation manners with reference to the accompanying drawings.

It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present application.

In the detailed description and claims of the present application, their names may be different.

[0055] The terms used in this specification are for the purpose of describing the embodiments of the present application, but are not intended to limit the present application. It should also be noted that unless otherwise clearly defined and limited, if terms such as "set", "connected", "connected" are used, they should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, a direct connection, or an indirect connection through an intermediate medium, and it can be the communication inside two elements. For those skilled in the art, the specific meanings of the above terms in the present application can be specifically understood.

[0056] As Figure 1 、 Figure 2 shown, a modular sorting actuator includes a power device 1 and a cam drive module 2. The power device 1 is connected to the cam drive module 2 to provide a power source for the cam drive module 2.

[0057] Further, the cam drive module 2 includes a camshaft assembly 5, a tappet assembly 6, a fork assembly 7, and a push plate assembly 8. The push plate assembly 8 is in cooperation with the camshaft assembly 5 along the Z direction through the tappet assembly 6. The power device 1 drives the camshaft assembly 5 of the cam drive module 2 to rotate continuously. One end of the fork assembly 7 is always in contact with the low position of the camshaft assembly 5. The curved surface contour of the camshaft assembly 5 has the characteristic of transitioning from a straight line to a curve along the X direction. One end of the fork assembly 7 abuts against the low position of the curved surface contour of the camshaft assembly 5. The fork assembly 7 has a degree of freedom of reciprocating displacement along the X direction;

[0058] When sorting needs to be performed, the fork assembly 7 pushes the curved surface contour of the camshaft assembly 5 to move, so as to realize the position change of the tappet assembly 6 between the low position and the high position of the curved surface contour of the camshaft assembly 5, and then drives the push plate assembly 8 to generate a displacement change in the Z direction, so that when the fork assembly 7 cooperates with the high position of the curved surface contour of the camshaft assembly 5, the push plate assembly 8 can strike the material and change the movement trajectory of the material.

[0059] It should be added that with the above settings, the power device 1 drives the camshaft assembly 5 of the cam drive module 2 to rotate continuously. One end of the fork assembly 7 is always in contact with the low position of the camshaft assembly 5. At this time, the fork assembly 7 will not have a vertical displacement in the Z direction, let alone drive the push plate assembly 8 to move upward to strike the material. Only when the system sends a control signal to the fork assembly 7, and the fork assembly 7 controls the camshaft assembly 5 to move in the X direction, one end of the tappet assembly 6 is displaced from the low position of the camshaft assembly 5 to the high working position, and then drives the push plate assembly 8 to perform the sorting action, changing the movement trajectory of the material to be sorted, so that the material to be sorted deviates from the original parabolic movement trajectory, and the material to be sorted and the material that does not need to be sorted are separated.

[0060] It should be emphasized that this kind of movement is non-regular movement. Only after the fork assembly 7 pushes the curved surface contour of the cam drive module 2 to displace, the bottom end of the tappet assembly 6 will be displaced from the low position on the surface of the curved surface contour of the camshaft assembly 5 to the high working position, generating a vertical displacement change, and it has been in a static state before that.

[0061] This setting ensures that one end of the fork assembly 7 is always in stable contact with the low position of the camshaft assembly, avoiding unnecessary Z-direction displacement, and significantly improving the stability and energy utilization efficiency of the system. In addition, this setting not only simplifies the operation process, enhances the flexibility and adaptability of the system, can be flexibly adjusted according to different needs, but also reduces the start-stop times and impact load of the equipment, helps to extend the service life of the overall equipment, and at the same time ensures the high precision and consistency of the sorting action.

[0062] In some preferred embodiments, the sorting execution mechanism further includes a position sensor 3. The position sensor 3 is an encoder and is used to measure the rotation angle or linear displacement of the cam drive module 2.

[0063] In some preferred embodiments, the number of the cam drive modules 2 is at least one set. When the number of the cam drive modules 2 is multiple, two adjacent cam drive modules 2 are connected end to end along the X direction, and the camshafts 10 of the power devices of two adjacent cam drive modules 2 are coaxially connected to jointly form a modular cam drive module combination. At this time, the power device 1 and the position sensor 3 are respectively arranged at two ends of the modular cam drive module combination along the X direction, so that each cam drive module 2 is both independent and can be separately disassembled, and can also be combined and spliced to share a power device 1 to achieve cooperative driving.

[0064] In some preferred embodiments, for facilitating sorting, when multiple camshaft assemblies 5 are coaxially connected, the initial positions of the cam drive module 2 and the fork assembly 7 are the same, that is, when looking along the X direction, the curved surface contours of the cam drive modules 2 are all in relatively consistent positions during rotation, that is, the semi-heterogeneous cams 11 of the camshaft assemblies 5 have the same initial position and rotation angle on the camshaft 10, and the relative position of the fork assembly 7 relative to the cam drive module 2 on the X axis is the same, which is used to facilitate adjusting the rotation angle and position, so that when each camshaft assembly 5 drives the tappet assembly 6 to move, it can be carried out orderly.

[0065] In some preferred embodiments, at least one set of the camshaft assemblies 5 is arranged in the same cam drive module 2, and the camshaft assemblies 5, the tappet assemblies 6, and the fork assemblies 7 are arranged in one-to-one correspondence. The number settings of the tappet assemblies 6 and the push plate assemblies 8 can either be in one-to-one correspondence or two tappet assemblies 6 correspond to the same push plate assembly 8. When multiple push plate assemblies 8 are correspondingly arranged in the same cam drive module 2, there is a gap between two adjacent push plate assemblies 8, so that the push plate assemblies 8 are independent of each other, so that the corresponding push plate assembly 8 can be selected according to the material sorting position to perform sorting, which is used to increase the flexibility of the push plate assemblies 8 hitting the material during the sorting process.

[0066] In some preferred embodiments, the cam drive module 2 further includes a housing 4. The tappet assembly 6 is arranged along the Z direction, and one end of the tappet assembly 6 passes through the housing 4 and is connected to the push plate assembly 8, and the lower bottom surface of the other end is in contact with the curved surface contour of the camshaft assembly 5, which is used to protect the camshaft assembly 5 and the fork assembly 7 and limit the Z-direction displacement of the tappet assembly 6.

[0067] The following combines the specification drawings to detail each component in the cam drive module 2.

[0068] Figure 4 This is a schematic structural diagram of the housing in the present application, asFigure 4 As shown, the outer housing 4 includes an upper cover 20, a base 21, a partition 22, a guide plate 23, and a gasket 24. The upper cover 20 is connected above the base 21. Lubricating oil is stored in the inner cavity of the base 21 to ensure smoother operation of the mechanism. The gasket 24 is connected to the joint between the upper cover 20 and the base 21, which can prevent the leakage of lubricating oil and also play a role in dust prevention.

[0069] In some preferred embodiments, a plurality of the partitions 22 are provided. The plurality of partitions 22 are arranged at intervals along the Y direction within the base 21, used to support a plurality of coaxially connected camshafts 10, and at the same time can play the role of defoaming and cooling the lubricating oil stored in the inner cavity.

[0070] In some preferred embodiments, the guide plate 23 is connected to a side plate on the side of the upper cover 20. The lower end of the tappet assembly 6 passes through the guide plate 23, used to prevent the tappet 17 from running off track, and at the same time can ensure that the tappet 17 and the semi-unusual cam 11 always maintain a line contact driving form, which is beneficial to reducing wear.

[0071] Figure 5 This is a structural schematic diagram of the camshaft assembly in the present application. As Figure 5 shown, the camshaft assembly 5 includes a camshaft 10 and a semi-unusual cam 11. The semi-unusual cam 11 is sleeved outside the camshaft 10 and has a displacement space along the X direction on the outer surface of the camshaft 10. One end of the semi-unusual cam 11 is a cylinder with equal diameter, and the other end is a special-shaped curved surface contour extending along its radial direction, ensuring that the mechanism has two working states of performing sorting and not performing sorting. When not performing sorting, one end of the tappet assembly 6 always stably contacts the outer surface of the cylinder of the semi-unusual cam 11, and the rotating cylinder surface will not cause unnecessary Z-direction displacement to the push plate assembly 8. Only when it is necessary to perform the sorting action, the fork assembly 7 will push the semi-unusual cam 11 to displace along the X direction until the tappet assembly 6 contacts the special-shaped curved surface contour of the semi-unusual cam 11. The mechanical cooperation greatly reduces the use cost, does not require continuous air supply at the power device 1, and increases the flexibility of sorting execution, and can realize the non-regular Z-direction displacement of the push plate assembly 8.

[0072] In some preferred embodiments, splicing interfaces are respectively provided at both end faces of the camshaft 10 in the camshaft assembly 5. As Figure 6 shown, for example, in the form of concave-convex cooperation between the convex portion 101 and the concave portion 102, two adjacent camshaft assemblies 5 are coaxially connected through the camshaft 10 to ensure that each camshaft assembly 5 can operate independently or can be spliced and used.

[0073] In some preferred embodiments, Figure 7 is a schematic structural diagram of the fork assembly in the present application. As Figure 7 shown, the fork assembly 7 includes a paddle 16 and an electromagnet 15. One end of the paddle 16 is connected to the electromagnet 15, and the other end extends outward and abuts against the outer surface of the semi-heterogeneous cam 11. Under the action of the electromagnet 15, the paddle 16 undergoes a reciprocating displacement along the X direction.

[0074] The tappet assembly 6 includes a tappet 17, a return spring 18, and a mounting seat 19. As Figure 8 shown, one end of the tappet 17 passes through the mounting seat 19, and a ring-shaped boss is provided in the middle of the other end. The return spring 18 is sleeved between the mounting seat 19 and the ring-shaped boss. The mounting seat 19 is connected to the outer housing 4 to support the tappet 17. The return spring 18 can buffer the cooperation between the tappet 17 and the push plate assembly 8 and also play a resetting role, thereby effectively improving the life of the system.

[0075] In some preferred embodiments, the tappet assembly 6 is connected to the push plate assembly 8 through the link mechanism 9. When the link mechanism 9 connects the tappet assembly 6 and the push plate assembly 8, it can achieve flexible conversion of the motion form, meet specific trajectory requirements, improve the load-bearing capacity and lubrication performance, increase the structural flexibility, and simplify the manufacturing and maintenance processes.

[0076] In some preferred embodiments, the push plate assembly 8 includes a push plate 12, a pressing plate 14, and a wear-resistant plate 13. The push plate 12 is made of steel to ensure reliable operation of the mechanism. One end of the bottom of the push plate 12 is connected to the tappet assembly 6, and the other end is hinged to the column at the top of the outer housing 4. One end of the wear-resistant plate 13 is connected in cooperation with the hinged end of the push plate 12 and is pressed by the pressing plate 14. The wear-resistant plate 13 is made of polyurethane material to improve the wear resistance of the mechanism. The pressing plate 14 is used to press the push plate 12 and the wear-resistant plate 13 tightly.

[0077] In some preferred embodiments, the present application also provides an intelligent dry separator. As Figure 10 shown, it is provided with the modular sorting execution mechanism as described above, and further includes a feeding mechanism 30, a feeding mechanism 40, a detection mechanism 50, and a control mechanism. The feeding mechanism 30 is used to feed the material to be sorted into the feeding mechanism 40. The feeding mechanism 40 is used to obtain the material to be sorted from the output end of the feeding mechanism 30 and convey the material to be sorted so that the material to be sorted can be thrown out from the output end of the feeding mechanism 40 at an initial speed.

[0078] In some preferred embodiments, the detection mechanism 50 is disposed above the conveyed material of the feeding mechanism 40, and is used to detect the material to be sorted conveyed on the feeding mechanism 40, so as to detect whether the material to be sorted is a material to be sorted or a material that does not need to be sorted. When the material to be sorted is a material to be sorted, the size and position of the material to be sorted are detected.

[0079] In some preferred embodiments, the control mechanism is configured to, according to the detection result of the detection mechanism 50, when the material to be sorted is a material to be sorted, send a control signal to the fork assembly 7 according to the size and position of the material to be sorted. The fork assembly pushes the semi-odd cam 11 to displace in the X direction, and then drives the tappet assembly 6 to displace from the low position to the high position along the Z direction of the camshaft assembly 5, and drives the material to be sorted to displace upward corresponding to the push plate assembly 8 to strike the material, so that the material to be sorted deviates from the original parabolic motion trajectory.

[0080] The specific embodiments of the present application have been described in detail above. For those skilled in the art of this technology, without departing from the principle of the present application, several improvements and modifications can still be made to the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
