Description

Technical Field

[0001] The present application relates to the field of jewelry processing, and in particular to an automatic jewelry grinding machine. Background Art

[0002] A traditional jewelry grinder typically consists of a rotating grinding barrel and a container containing abrasive and jewelry. During the grinding process, the operator first places the jewelry to be processed into the grinding barrel and then adds the appropriate amount of abrasive. The abrasive can be a variety of granular materials, such as corundum or quartz sand, and is used to grind and polish the jewelry surface. Once loaded, the grinder begins. A motor or other power device rotates the grinding barrel rapidly, driving the abrasive as well. As it rotates, the abrasive continuously contacts the jewelry surface, achieving the desired grinding and polishing effect. This process can take some time to ensure the jewelry surface is fully prepared. Once the jewelry processing is complete or the desired polishing level is achieved, the operator stops the grinder. At this point, the abrasive and jewelry in the grinding barrel are mixed and need to be separated. Traditional jewelry grinders require this step manually. The operator opens the grinder's lid and pours the mixture from the grinding barrel into a screen or other separation device. The screen then filters the jewelry and abrasive, but manual separation is inefficient, affecting jewelry grinding efficiency.

[0003] For this reason, it is necessary to design an automatic grinding machine that can automatically separate abrasives and jewels to solve the problem of low efficiency of manual separation of abrasives and jewels. Utility Model Content

[0025] The embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0026] It should be noted that when a component is considered to be "connected to" another component, it can be directly connected to the other component or there may be an intermediate component. When a component is considered to be "disposed on" another component, it can be directly disposed on the other component or there may be an intermediate component.

[0027] An embodiment of the present application provides an automatic jewelry grinding machine, comprising:

[0028] A grinding barrel, wherein the grinding barrel is provided with a baffle having a first mesh portion, and the interior of the grinding barrel is connected to the outside of the grinding barrel through the first mesh portion;

[0029] an abrasive barrel, the abrasive barrel being slidably connected to the grinding barrel, the abrasive barrel having a second mesh portion, the interior of the abrasive barrel being connected to the exterior of the abrasive barrel via the first mesh portion, the first mesh portion being fitted with the second mesh portion, and the abrasive barrel and the grinding barrel sliding relative to each other to drive the first mesh portion and the second mesh portion to be connected to or blocked from each other;

[0030] The tilting mechanism is configured such that the grinding barrel and the abrasive barrel are arranged on the tilting mechanism, and the tilting mechanism pushes the abrasive barrel toward or away from the tilting mechanism in a first direction parallel to the direction of gravity, and adjusts the spatial position relationship between the abrasive barrel and the grinding barrel to control the flow direction of the abrasive. The automatic jewelry grinding machine provided above is designed with a tilting mechanism and an abrasive barrel. The abrasive barrel is not connected to the grinding barrel during the grinding process. After the grinding is completed, the grinding barrel slides to a position connected to the abrasive barrel. At the same time, the tilting mechanism pushes the abrasive barrel to move, changing the position between the abrasive barrel and the grinding barrel, so that the abrasive in the grinding barrel flows into the abrasive barrel under the action of gravity, while the jewelry remains in the grinding barrel under the action of the baffle, thereby automatically separating the jewelry from the abrasive.

[0031] The following embodiments of the present application are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0032] See also Figure 1-Figure 4The embodiment of the present application provides an automatic jewelry grinding machine 100, including a grinding barrel 1, an abrasive barrel 2 and a tilting mechanism 3. The grinding barrel 1 is provided with a baffle 11, and the baffle 11 has a first leakage part 111. The interior of the grinding barrel 1 is connected to the outside of the grinding barrel 1 through the first leakage part 111. The abrasive barrel 2 is slidably connected to the grinding barrel 1. The abrasive barrel 2 has a second leakage part 21. The interior of the abrasive barrel 2 is connected to the outside of the abrasive barrel 2 through the first leakage part 111. The first leakage mesh part 111 is fitted with the second leakage mesh part 21, and the first leakage mesh part 111 and the second leakage mesh part 21 are connected to or blocked from each other by sliding between the abrasive barrel 2 and the grinding barrel 1. The grinding barrel 1 and the abrasive barrel 2 are arranged on the tilting mechanism 3. The tilting mechanism 3 pushes the abrasive barrel 2 toward or away from the tilting mechanism 3 along a first direction parallel to the direction of gravity, and adjusts the spatial position relationship between the abrasive barrel 2 and the grinding barrel 1 to control the flow direction of the abrasive.

[0033] Specifically, the grinding barrel 1 is the main container for jewelry grinding, and the function of the baffle 11 is to limit the flow of abrasive to ensure the stability and consistency of grinding. The first mesh portion 111 on the baffle 11 allows the abrasive to flow into the grinding barrel 1, and at the same time is connected to the outside of the grinding barrel 1 to ensure the supply and discharge of the abrasive. When the abrasive in the abrasive barrel 2 needs to enter the grinding barrel 1 for grinding, the second mesh portion 21 on the abrasive barrel 2 is aligned with the first mesh portion 111 on the baffle 11 to form a channel. In this case, the abrasive can smoothly pass through the first mesh portion 111 into the grinding barrel 1, thereby completing the grinding process. This connected state ensures the normal supply of abrasive and ensures the continuous progress of the grinding process. When it is necessary to prevent the abrasive from entering the grinding barrel 1, the second mesh portion 21 on the abrasive barrel 2 is misaligned or separated from the first mesh portion 111 on the baffle 11. This misalignment or separation causes the first mesh portion 111 and the second mesh portion 21 to not fit together, forming a barrier and preventing the flow of abrasive. In this state, the abrasive cannot enter the grinding barrel 1, thereby achieving the barrier of the abrasive. The mutual sliding between the abrasive barrel 2 and the grinding barrel 1 is achieved by an external pushing mechanism or an internal transmission device. When the two slide, the second leakage mesh part 21 on the abrasive barrel 2 will be aligned or misaligned with the first leakage mesh part 111 on the baffle 11 accordingly, thereby achieving the state switching of connection or blocking. This actuation process can be controlled by a mechanical structure or an electric device to ensure precise control and flexible operation of the grinding process.

[0034] Furthermore, the abrasive barrel 2 is a container for storing abrasives, and the tilting mechanism 3 pushes the abrasive barrel 2 to move in a first direction of gravity, where the direction of gravity is parallel to the direction of local gravity. By changing the position of the abrasive barrel 2 in the direction of gravity, when the position of the abrasive barrel 2 is higher than that of the grinding barrel 1, the abrasive in the abrasive barrel 2 will flow to the grinding barrel 1; and when the position of the abrasive barrel 2 is lower than that of the grinding barrel 1, the abrasive will flow from the grinding barrel 1 to the abrasive barrel 2.

[0035] In a specific example, the grinding barrel 1 is provided with a sliding groove 12, and the abrasive barrel 2 is provided with a slider 22. The slider 22 slides in the sliding groove 12. The abrasive barrel 2 is transmission-connected to the grinding barrel 1 through the slider 22. The slider 22 moves to one end of the sliding groove 12 to drive the grinding barrel 1 to move along with the slider 22.

[0036] Specifically, when the grinding barrel 1 and the abrasive barrel 2 are combined together, the slider 22 is received in the sliding groove 12. When the abrasive barrel 2 rotates relative to the grinding barrel 1, the slider 22 also slides in the sliding groove 12 along with the movement of the abrasive barrel 2. The grinding barrel 1 is provided with one or more sliding grooves 12, which are usually grooves or channels embedded along the outer surface of the grinding barrel 1. When the slider 22 moves to one end of the sliding groove 12, the abrasive barrel 2 continues to rotate under the drive of external force, thereby driving the grinding barrel 1 to rotate together with the abrasive barrel 2, achieving the effect of transmission connection. The slider 22 acts as the part of the abrasive barrel 2 extending into the grinding barrel 1, and acts as a transmission component.

[0037] In a specific example, a transmission assembly 31 is provided on the tilting mechanism 3, the abrasive barrel 2 is rotatably connected to the tilting mechanism 3, the transmission assembly 31 is transmission-connected to the abrasive barrel 2, the abrasive barrel 2 is transmission-connected to the grinding barrel 1 through the slider 22, the transmission assembly 31 drives the abrasive barrel 2 to rotate, and the abrasive barrel 2 drives the grinding barrel 1 to rotate.

[0038] Specifically, the tilting mechanism 3 is provided with a transmission assembly 31, which can be a component of various mechanical transmission devices. The design purpose is to drive the abrasive barrel 2 to move, which is usually achieved by using a motor 311 as a power source. The abrasive barrel 2 is connected to the tilting mechanism 3 through a rotational connection. This connection is usually achieved through bearings or other rotating connection devices to ensure that the abrasive barrel 2 can rotate around its own axis. The transmission assembly 31 on the tilting mechanism 3 is connected to the abrasive barrel 2 through a transmission connection, so that the tilting mechanism 3 can control the rotational movement of the abrasive barrel 2. This transmission connection is usually achieved through transmission devices such as gears, chains, and belts. By driving the abrasive barrel 2 to rotate through the transmission assembly 31 on the tilting mechanism 3, the abrasive barrel 2 can begin to rotate along its own axis. This rotational movement can be adjusted as needed to meet the requirements of different processing technologies.

[0039] In a specific example, the transmission assembly 31 includes a motor 311 and a synchronous belt transmission member 312 , and the synchronous belt transmission member 312 is respectively connected to the motor 311 and the abrasive barrel 2 .

[0040] Specifically, the transmission assembly 31 is a mechanical device for transmitting power and motion. In this patented design, the transmission assembly 31 also provides power to the abrasive barrel 2. It includes a motor 311 and a synchronous belt drive 312. The motor 311 is the power-generating component, converting electrical energy into mechanical motion. In this scenario, the motor 311 provides rotational power to drive the abrasive barrel 2. The synchronous belt drive 312 is a transmission device for transmitting power and motion, typically consisting of a synchronous belt and corresponding gears. The synchronous belt drive 312 may consist of a synchronous belt and matching gears, connecting the motor 311 and the abrasive barrel 2. One end of the synchronous belt drive 312 is connected to the motor 311, and the power provided by the motor 311 drives the movement of the synchronous belt drive 312. The other end of the synchronous belt drive 312 is connected to the abrasive barrel 2, and the power transmitted by the synchronous belt drive 312 drives the rotation of the abrasive barrel 2. This connection may be achieved through a transmission device such as a gear, a chain, or a belt to ensure that the power provided by the motor 311 can be smoothly transmitted to the abrasive barrel 2.

[0041] In a specific example, the tilting mechanism 3 includes an upper plate 32 and a lower plate 33 rotatably connected to the upper plate 32. The grinding barrel 1 and the abrasive barrel 2 are arranged on the upper plate 32. A first rotating part 321 is provided on the side of the upper plate 32 away from the grinding barrel 1. The distance between the first rotating part 321 and the two ends of the upper plate 32 is equal. A second rotating part 331 is provided on the side of the lower plate 33 close to the upper plate 32. The upper plate 32 and the lower plate 33 are rotatably connected through the first rotating part 321 and the second rotating part 331.

[0042] Specifically, the upper plate 32 and the lower plate 33 are connected by a rotational connection, which can be achieved through bearings, pins, or other rotational connection devices. This ensures a secure connection and free rotation between the upper and lower plates 32, 33, allowing them to rotate relative to each other. The grinding barrel 1 and the abrasive barrel 2 are placed on the upper plate 32, allowing them to tilt and adjust accordingly as the upper plate 32 rotates. A first rotating portion 321 is provided on the side of the upper plate 32 facing away from the grinding barrel 1, while a second rotating portion 331 is provided on the side facing closer to the grinding barrel 1. The first and second rotating portions 321, 331 may be part of bearings, pins, or other rotational connection devices, and they facilitate the rotational connection between the upper and lower plates 32, 33. The first rotating portion 321 is equidistant from both ends of the upper plate 32, ensuring balanced and stable rotation of the upper plate 32. The rotational connection between the first and second rotating portions 321, 331 allows for flexible adjustment and control of the tilting mechanism 3.

[0043] In a specific example, the upper plate 32 has a support portion 322 , the abrasive barrel 2 is transmission-connected to the support portion 322 , and the motor 311 is disposed between the abrasive barrel 2 and the upper plate 32 .

[0044] Specifically, the supporting portion 322 is used to support the abrasive barrel 2 so that there is a space between the abrasive barrel 2 and the upper plate 32 for installing structures such as the transmission assembly 31.

[0045] The design of the support part 322 needs to leave enough space to accommodate structures such as the transmission assembly 31. These transmission assemblies 31 may include a motor 311, a synchronous belt transmission 312, gears, chains, etc., and there needs to be enough space between them and the abrasive barrel 2 to install and operate. The support part 322 not only provides support, but also needs to provide a transmission connection function. The transmission assembly 31 usually needs to be installed on the support part 322 and connected to the abrasive barrel 2 to achieve the purpose of the motor 311 providing power and transmitting it to the abrasive barrel 2. The design of the support part 322 needs to take into account the balance and stability of the entire tilting mechanism 3. A good design of the support part 322 can ensure that the abrasive barrel 2 remains balanced during operation, avoiding vibration or shaking caused by instability, thereby affecting the processing quality and equipment life.

[0046] In a specific example, a hydraulic support rod 332 is provided on the lower plate 33 , and the hydraulic support rod 332 is transmission-connected with the upper plate 32 . The hydraulic support rod 332 pushes the upper plate 32 to rotate around the lower plate 33 .

[0047] Specifically, the hydraulic support rods 332 are devices that utilize hydraulic principles to provide support and motion control. In this scenario, the hydraulic support rods 332 are used to control the tilt angle of the tilting mechanism 3, thereby adjusting the flow direction of the abrasive and the processing process. These hydraulic support rods 332 are mounted on the lower plate 33 of the tilting mechanism 3. These hydraulic support rods 332 can use hydraulic force to rotate the upper plate 32. The hydraulic support rods 332 are connected to the upper plate 32 via a fixing device or other connector that can accommodate the motion relationship between the hydraulic support rods 332 and the upper plate 32. Through this connection, the hydraulic support rods 332 can apply force and control the movement of the upper plate 32. When the hydraulic support rods 332 are subjected to hydraulic pressure, they exert force to propel the upper plate 32 to rotate about the lower plate 33. When controlled by hydraulic pressure, the hydraulic support rods 332 apply force to the upper plate 32 according to the set pressure and flow rate, thereby rotating the upper plate 32. This rotational motion can be adjusted as needed to meet the requirements of different processing processes.

[0048] In a specific example, the grinding barrel 1 is provided with two baffles 11, and the two baffles 11 are respectively located at the two ends of the grinding barrel 1, and the two abrasive barrels 2 are respectively provided at the two ends of the grinding barrel 1, and the tilting mechanism 3 is provided with two transmission components 31, and one abrasive barrel 2 is transmission-connected to one transmission component 31.

[0049] Specifically, arranging two abrasive barrels 2 on the grinding barrel 1 can reduce the working frequency of the tilting mechanism 3. Sliding grooves 12 are opened at both ends of the grinding barrel 1. The opening directions of the two sliding grooves 12 are opposite and staggered. This is to stagger the two abrasive barrels 2. When one of the abrasive barrels 2 is rotated to be connected with the grinding barrel 1 due to the drive of the transmission component 31, the other abrasive barrel 2 is in a state of being disconnected from the grinding barrel 1 due to the opening direction of the corresponding sliding groove 12. This ensures that only one abrasive barrel 2 is connected with the grinding barrel 1 when the abrasive barrel 2 and the grinding barrel 1 rotate. If the two abrasive barrels 2 are connected with the grinding barrel 1 at the same time, the abrasive cannot stay in the grinding barrel 1. The two abrasive barrels 2 are each equipped with a set of transmission components 31 to improve the working efficiency of the machine.

[0050] In a specific example, the tilting mechanism 3 also includes a rotating rod 34, which passes through the first rotating part 321 and the second rotating part 331. The upper plate 32 and the lower plate 33 use the rotating rod 34 as a rotation axis, and the upper plate 32 and the lower plate 33 rotate around the length direction of the rotating rod 34.

[0051] Specifically, the rotating rod 34 is a key component of the tilt mechanism 3 . Its primary function is to serve as a rotational axis, enabling the upper and lower plates 32 and 33 to rotate about the rotating rod 34 . The rotating rod 34 extends through the first rotating portion 321 and the second rotating portion 331 of the tilt mechanism 3 . This means that the rotating rod 34 is connected to the upper and lower plates 32 and 33 via the first and second rotating portions 321 and 331 . The rotating rod 34 is typically an axis-like structure, with a length tailored to the overall dimensions of the tilt mechanism 3 , ensuring that the upper and lower plates 32 and 33 are securely mounted on the rotating rod 34 . The upper and lower plates 32 and 33 are connected by the rotating rod 34 , located on either side of the rotating rod 34 . The rotating rod 34 serves as a connection point, enabling the upper and lower plates 32 and 33 to rotate about the rotating rod 34 . This connection ensures relative motion between the upper and lower plates 32 and 33 about a fixed axis, thereby enabling adjustment and control of the tilt mechanism 3 . The upper plate 32 and the lower plate 33 rotate about the length of the rotating rod 34, which means that their rotation axes are parallel to the length of the tilt mechanism 3. With the rotating rod 34 as the rotation axis, the upper plate 32 and the lower plate 33 can achieve rotational movement about the axis, thereby adjusting the angle and position of the tilt mechanism 3.

[0052] In a specific example, the support portion 322 is threadedly connected to the upper plate 32 .

[0053] Specifically, the support portion 322 is a structural component within the tilting mechanism 3, typically used to support the abrasive barrel 2 or other related components to ensure the stability and proper operation of the entire mechanism. In this description, the support portion 322 is connected to the upper plate 32 using a threaded connection. Threaded connections are a common mechanical connection method that connects and secures components through the interlocking of threads. The support portion 322 may have a threaded structure on its surface to facilitate threaded connection with a corresponding portion on the upper plate 32. Typically, the support portion 322 will have a certain strength and stability to ensure a secure and reliable connection. The upper plate 32 may have a hole or threaded structure that matches the thread of the support portion 322. Thus, when the support portion 322 is inserted into the threaded hole of the upper plate 32, it can be tightly connected to the upper plate 32 by rotating the support portion 322. The threaded connection allows the support portion 322 to be removed from the upper plate 32, thereby better securing the abrasive barrel 2 and the grinding barrel 1 between the two support portions 322.

[0054] The above is only an implementation method of the present application. It should be pointed out that for ordinary technicians in this field, improvements can be made without departing from the creative concept of the present application, but these all fall within the scope of protection of the present application.
