Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, and in particular to a precious metal processing device and its material separation mechanism. Background Technology

[0002] In the recycling, refining, and jewelry manufacturing of precious metals (such as gold, silver, and platinum), multiple raw materials are typically processed in a single production run, necessitating separation during processing. However, current separation methods are usually manual, which is not only inefficient but also requires a high level of operator skill, resulting in inconsistent separation quality. Furthermore, due to the high price of precious metals, manual intervention can lead to trust issues and disputes if raw materials are missing or have abnormal weights. Utility Model Content

[0003] In view of this, the present invention provides a precious metal processing device and its material separation mechanism to solve the above problems.

[0004] On one hand, this application provides a material separation mechanism, including a belt drive structure, a discharge structure, and a drive structure. The discharge structure is located at one end of the belt drive structure, and the belt drive structure is used to transport materials to the discharge structure. The discharge structure includes an inlet and an outlet. The inlet faces the belt drive structure, and the outlet faces an angle with the inlet. The drive structure can move relative to the discharge structure and is used to drive the materials in the discharge structure to move towards the outlet.

[0005] On the other hand, this application also provides a precious metal processing apparatus, including the material separation mechanism described above.

[0006] The material separation mechanism provided by this utility model uses a belt drive structure to transport materials through the inlet to the outlet structure. The drive structure can drive the materials on the outlet structure to be discharged from the outlet, achieving automatic feeding and discharging. Furthermore, because the orientation of the inlet and the outlet are different, the movement direction of the materials when entering the outlet structure is different from the movement direction of the materials when discharging from the outlet structure. By changing the movement direction of the materials, automatic separation of materials is achieved without human intervention. This not only improves separation efficiency and quality but also avoids trust crises and disputes caused by separation. Attached Figure Description

Detailed Implementation

[0009] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0010] It should be noted that all directional indicators (such as up, down, left, right, front, back, inside, outside, top, bottom, etc.) in the embodiments of this utility model are only used to explain the relative positional relationship between the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0011] It should also be noted that when a component is referred to as "fixed to" or "set on" another component, the component may be directly on the other component or there may be an intervening component present. When a component is referred to as "connected to" another component, it may be directly connected to the other component or there may be an intervening component present.

[0012] Please see Figures 1 to 5This utility model provides a material separation mechanism 100, which includes a belt drive structure 10, a discharge structure 12, and a drive structure 14. The discharge structure 12 is located at one end of the belt drive structure 10. The belt drive structure 10 is used to transport material 200 to the discharge structure 12. Optionally, the material 200 is a cardboard box containing precious metal. The drive structure 14 can move relative to the discharge structure 12 to push the material 200 on the discharge structure 12 to move.

[0013] The discharge structure 12 includes an inlet 18 and an outlet. The inlet 18 faces the belt drive structure 10, meaning it is located on the side of the discharge structure 12 closest to the drive belt structure. When the belt drive structure 10 drives the material 200 to move towards the discharge structure 12, the material 200 can enter the discharge structure 12 through the inlet 18. The orientation of the outlet forms an angle with the orientation of the inlet 18. The orientation of the outlet is the direction of movement of the material 200 when it exits the discharge structure 12. The drive structure 14 drives the material 200 inside the discharge structure 12 towards the outlet. The orientation of the inlet 18 is the direction of movement of the material 200 when it enters the discharge structure 12. The belt drive structure 10 drives the material 200 towards the inlet 18, causing the material 200 on the discharge structure 12 to exit from the outlet. The orientation of the outlet forms an angle with the orientation of the inlet 18, meaning the feeding direction and the discharging direction of the discharge structure 12 are different. By setting up a belt drive structure 10, a discharge structure 12, and a drive structure 14, the discharge structure 12 can achieve automatic feeding through the belt drive structure 10 and automatic discharge through the drive structure 14. Furthermore, the feeding direction and the discharge direction of the material 200 are different. By changing the movement direction of the material 200, the material 200 can be separated without human intervention. This not only improves separation efficiency and quality but also avoids trust crises and disputes caused by separation.

[0014] In an optional example, the orientation of the discharge port is perpendicular to the orientation of the inlet 18, that is, the direction of movement of the material 200 when it enters the discharge structure 12 from the belt drive structure 10 (i.e., the feeding direction) is perpendicular to the direction of movement of the material 200 when it exits the belt drive structure 10 (i.e., the discharge direction), so as to achieve separation of the material 200.

[0015] The belt drive structure 10 can move multiple materials 200 at a time, while the discharge structure 12 can hold one material 200 at a time. The width of the discharge port is greater than the width of one material 200 but less than the width of two materials 200. Since the discharge structure 12 can only hold one material 200 at a time, the multiple materials 200 on the belt drive structure 10 can only enter the discharge structure 12 one by one in sequence, and the drive structure 14 drives one material 200 at a time to move towards the discharge port.

[0016] In an alternative example, material 200 is a cardboard box containing precious metals. The volume and weight of the precious metals inside the cardboard box are small, resulting in a low overall weight of material 200. The belt drive structure 10 drives material 200 to move through the friction between the conveyor belt and material 200. The magnitude of the friction is positively correlated with the weight of material 200. The low weight of material 200 results in low friction, which may cause material 200 to slip and not move well with the belt drive structure 10.

[0017] The material separation mechanism 100 also includes a pusher block 20, the weight of which is greater than the weight of a single material 200. Therefore, the friction between the pusher block 20 and the belt drive structure 10 is greater than the friction between the material 200 and the belt drive structure 10. During the transport of the material 200 by the belt drive structure 10, the pusher block 20 is positioned behind the material 200 and abuts against it. Due to the relatively large friction between the pusher block 20 and the belt drive structure 10, slippage is less likely, and the pusher block 20 can stably move with the belt drive structure 10. The pusher block 20 can push the material 200 located in front of it to move together, and even if the friction between the material 200 and the belt drive structure 10 is small, it can still move stably towards the discharge structure 12. Optionally, the belt drive structure 10 is used to move multiple materials 200 simultaneously, with the pusher block 20 positioned behind the last material 200 and abutting against it.

[0018] In one embodiment, the material separation mechanism 100 further includes a sensor 22, which is located on the side of the discharge structure 12 away from the discharge port and is electrically connected to the transmission structure and the drive structure 14. The sensor 22 is used to detect the position of the material 200 within the discharge structure 12. When the sensor 22 detects that the material 200 is at a preset position in the discharge structure 12, the material 200 is positioned directly opposite the discharge port, the belt drive structure 10 stops moving, thereby temporarily stopping the transport of the material 200, and the drive structure 14 moves relative to the discharge structure 12, driving the material 200 at the preset position towards the discharge port, so that the material 200 is discharged from the discharge port. During the material discharge process, when the drive structure 14 drives the material 200 to move towards the discharge port, the belt drive structure 10 will stop moving first, that is, stop feeding. After the previous material 200 is discharged along the discharge port and the drive structure 14 is reset, the belt drive structure 10 will feed again. The feeding and discharging of the discharge structure 12 are staggered in time to prevent the feeding and discharging from interfering with each other, and at the same time, it can better separate the material 200.

[0019] The specific type of sensor 22 is not limited, such as pressure sensor 22, photoelectric sensor 22, etc., as long as it can detect the position of material 200. In an optional example, when material 200 moves to contact with sensor 22, sensor 22 determines that material 200 has moved to a preset position.

[0020] The specific location of the drive structure 14 is not limited. For example, it can be located between the discharge structure 12 and the belt drive structure 10, or it can be located on the side of the discharge structure 12 away from the belt drive structure 10, or it can be located on the side of the discharge structure 12 away from the discharge port, as long as it can drive the material 200 in the discharge structure 12 to move towards the discharge port.

[0021] In one embodiment, the drive structure 14 is at least partially located between the belt drive structure 10 and the discharge structure 12. The drive structure 14 is provided with a clearance opening 30, which is located between the belt drive structure 10 and the feed inlet 18 and is connected to the feed inlet 18. That is, the clearance opening 30 is located in the area of ​​the drive structure 14 between the belt drive structure 10 and the discharge structure 12. The size of the clearance opening 30 is larger than the size of the material 200. When the belt drive structure 10 moves the material 200 to the discharge structure 12, the material 200 can move to the discharge structure 12 through the clearance opening 30.

[0022] The drive structure 14 includes a fixed member 24 fixed relative to the discharge structure 12, a movable member 26 movably engaged with the fixed member 24, and a drive member 28 connected to the movable member 26. The fixed member 24 is located between the discharge structure 12 and the belt drive structure 10, and a clearance opening 30 is provided through the fixed member 24. The movable member 26 is movably engaged with the fixed member 24, and the drive member 28 is used to drive the movable member 26 to move relative to the fixed member 24, thereby causing the movable member 26 to move relative to the discharge structure 12, so as to drive the material 200 on the discharge structure 12 to move.

[0023] Optionally, the fixing member 24 is a fixing plate, which is perpendicular to the length direction (i.e., the direction of movement) of the belt drive structure 10. The clearance opening 30 is a square opening that penetrates the fixing member 24. The orientation of the feed inlet 18 is consistent with the orientation of the clearance opening 30, so that the orientation of the feed inlet 18 is consistent with the direction of movement of the belt drive structure 10, so that the material 200 on the belt drive structure 10 enters the discharge structure 12 through the clearance opening 30 and the feed inlet 18. The movable member 26 is located on the side of the fixing plate closer to the discharge structure 12, and the driving member 28 is located above the clearance opening 30.

[0024] The specific type of the driving component 28 is not limited, such as a motor, cylinder, etc. In an optional example, the driving component 28 is a cylinder. The piston of the cylinder is fixed relative to the movable component 26. When the piston moves in extension and retraction, it drives the movable component 26 to move together. The extension and retraction direction of the piston is consistent with the orientation of the discharge port.

[0025] The movable part 26 has a mounting groove on the side near the driving part 28. A connector 31 is provided in the mounting groove. An annular groove is provided on the outer side of the connector 31. A protrusion is provided in the mounting groove. The protrusion is inserted into the annular groove, so that the movable part 26 and the connector 31 are kept relatively fixed in the discharge direction. The piston of the driving part 28 is fixedly connected to the connector 31, so that it is kept relatively fixed with the movable part 26 in the discharge direction.

[0026] In one embodiment, a sliding structure is provided between the fixed member 24 and the movable member 26. The fixed member 24 and the movable member 26 achieve sliding engagement through the sliding structure, so that the movable member 26 can slide relative to the fixed member 24 under the drive of the driving member 28.

[0027] In an optional example, the sliding structure is a linear bearing type sliding structure, which includes a slide rail 32 and a slider 34. The slide rail 32 is provided on the side of the fixed member 24 facing the movable member 26, and the slider 34 is provided on the side of the movable member 26 facing the fixed member 24. The slide rail 32 and the slider 34 are movably engaged, thereby forming a movable engagement between the movable member 26 and the fixed member 24. The slide rail 32 extends along the direction of the discharge port. During the movement of the movable member 26 driven by the drive member 28, the slider 34 slides along the extension direction of the slide rail 32. The engagement between the slider 34 and the slide rail 32 can play a limiting and guiding role, making the movement of the movable member 26 more stable relative to the fixed member 24.

[0028] Optionally, the number of sliders 34 and slide rails 32 can be one or more, with each slider 34 slidingly engaging with a corresponding slide rail 32. In an optional example, the number of sliders 34 and slide rails 32 is two, with the two slide rails 32 arranged parallel to each other at intervals along a direction perpendicular to their extension direction. Each slider 34 is movably engaged with a corresponding slide rail 32, and the piston of the drive member 28 is located between the two slide rails 32, making the sliding of the movable member 26 relative to the fixed member 24 more stable under the drive of the drive member 28.

[0029] In other embodiments, the sliding structure can also be a bushing-type sliding structure, which includes a guide rod and a bushing movably sleeved outside the guide rod. The bushing is connected to the movable part, and the guide rod is connected to the fixed part. The movable part can also slide relative to the fixed part under the drive of the driving part.

[0030] The movable component 26 includes a connecting portion 36 movably connected to the fixed component 24, and a pushing portion 38 connected to the connecting portion 36. The driving component 28 is connected to the connecting portion 36, and the pushing portion 38 extends from the connecting portion 36 in a direction away from the fixed component 24, and the pushing portion 38 is located on the side of the discharge structure 12 away from the discharge port. The connecting portion 36 and the pushing portion 38 form an L-shaped structure. The connecting portion 36 is used to connect with the fixed component 24 and the driving component 28. The pushing portion 38 can move towards the discharge port under the action of the driving component 28, thereby pushing the material 200 located between the pushing portion 38 and the discharge port to move, so that the material 200 moves towards the discharge port and is discharged from the discharge port.

[0031] The movable part 26 also includes a reinforcing part 40, which is connected to the connecting part 36 and the pushing part 38 to enhance the overall strength of the movable part 26. The reinforcing part 40, the connecting part 36, and the pushing part 38 can be integrally formed or separately connected.

[0032] The connecting part 36, the pushing part 38 and the reinforcing part 40 are all plate-shaped, and the three are perpendicular to each other in pairs. That is, any two of the connecting part 36, the pushing part 38 and the reinforcing part 40 form a perpendicular relationship.

[0033] In one embodiment, the discharge structure 12 includes a base plate 42 and a side plate 44. The base plate 42 is located on the side of the fixing member 24 away from the belt drive structure 10 and is used to support the material 200 transported by the belt drive structure 10. The side plate 44 is located on the side of the base plate 42 away from the fixing member 24 and is disposed opposite to the feed port 18 to limit the material 200 moving from the belt drive structure 10 and prevent the material 200 from falling off the side of the discharge structure 12 away from the feed port 18 along the feeding direction.

[0034] The feed inlet 18 is located on the side of the base plate 42 away from the side plate 44, and the discharge outlet is located on the side of the base plate 42 adjacent to the side plate 44. The pushing part 38 of the movable part 26 extends from the connecting part 36 toward the side plate 44 and is located on the side of the base plate 42 away from the feed inlet 18. That is, the pushing part 38 and the feed inlet 18 are located on opposite sides of the base plate 42, and the pushing part 38 is spaced a certain distance from the side plate 44 to prevent them from interfering with each other and affecting the movement of the movable part 26. The base plate 42 and the side plate 44 form an L-shaped structure, so that the discharge structure 12 has openings on the side away from the side plate 44 and on both sides adjacent to the side plate 44. The opening away from the side plate 44 serves as the feed inlet 18, one opening adjacent to the side plate 44 serves as the discharge outlet, and the other opening serves as the entrance for the pushing part 38 to enter the discharge structure 12. This makes the overall structure of the discharge structure 12 relatively simple while meeting the requirements of feeding and discharging.

[0035] Optionally, the base plate 42 is rectangular and includes a first side, a second side, a third side, and a fourth side. The first side and the third side are spaced apart and opposite to each other, and the second side and the fourth side are spaced apart and opposite to each other. The side plate 44 is connected to the first side of the base plate 42, the feed port 18 is located on the third side of the base plate 42, the discharge port is located on the second side of the base plate 42, and the pushing part 38 is located on the fourth side of the base plate 42.

[0036] The discharge structure 12 is provided with a guide trough 46 at the discharge port. The guide trough 46 is connected to the discharge port and extends along the direction of the discharge port. The material 200 on the discharge structure 12 can move from the discharge port to the guide trough 46 under the action of the drive structure 14. The guide trough 46 has the effect of limiting and guiding, so that after the material 200 is discharged from the discharge port, it can continue to move forward a certain distance along the discharge direction, so that the material 200 can be stably discharged along the preset trajectory and direction.

[0037] Optionally, the guide trough 46 is located on the side of the base plate 42 away from the pusher 38. The guide trough 46 is U-shaped and includes a bottom and two sides fixed to opposite sides of the bottom. The bottom is fixedly connected to the base plate 42 to support the material 200, and the two sides are used to limit and guide the material 200.

[0038] In one embodiment, the belt drive structure 10 includes a conveyor belt and a motor connected to the conveyor belt. The discharge structure 12 is located at one end of the conveyor belt. The motor drives the conveyor belt to move. When material 200 is placed on the conveyor belt, the conveyor belt can move the material 200 together, thereby transporting the material 200 to the discharge structure 12. The conveyor belt can transport multiple materials 200 at the same time, but the discharge structure 12 can only hold one material 200 at a time. Therefore, the material 200 on the discharge structure 12 must be discharged before the next material 200 can move in.

[0039] In one alternative example, the feed inlet 18 is oriented in the same direction as the length of the conveyor belt, and the discharge outlet is oriented in the same direction as the width of the conveyor belt, so that the feed direction and the discharge direction are perpendicular.

[0040] A cover 47 is provided above the conveyor belt. The cover 47 is U-shaped, with its two sides located on opposite sides of the conveyor belt. The cover 47 extends along the length of the conveyor belt. During the process of transporting material 200, the material 200 passes through the inside of the cover 47. The cover 47 can limit the material 200 and prevent it from falling off the conveyor belt during transport.

[0041] Understandably, in order to adjust the speed of the conveyor belt and thus the feed speed, a tensioner or speed controller can be installed to adjust the speed of the conveyor belt.

[0042] In one embodiment, the material separation mechanism 100 further includes a mounting frame 48 and a cabinet 50. The mounting frame 48 and the cabinet 50 are arranged opposite each other at a distance. One end of the belt drive structure 10 is mounted on the mounting frame 48, and the other end of the belt drive structure 10, as well as the drive structure 14 and the discharge structure 12, are mounted on the cabinet 50. Electrical components are provided inside the cabinet 50. The sensor 22, the drive structure 14, and the belt drive structure 10 are all electrically connected to the electrical components inside the cabinet 50 and work under the control of the electrical components.

[0043] This utility model also provides a precious metal processing apparatus, including a material separation mechanism 100, the specific structure of which can be referred to the description of the above embodiments. Since the precious metal processing apparatus adopts the above-mentioned material separation mechanism 100, it has at least all the beneficial effects brought about by the material separation mechanism 100 in the above embodiments, which will not be repeated here.

[0044] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
