[0031] The embodiment of the present application provides a bracelet surface sand rolling machine, comprising:

[0032] Power components;

[0033] A sliding plate, one end of which is transmission-connected to the power assembly, and the other end of which is provided with a plurality of sliding grooves, wherein the plurality of sliding grooves are arranged around the rotating axis of the sliding plate;

[0034] A sliding support member, the sliding support member is received in the sliding groove and is slidably connected with the sliding groove, a plurality of the sliding support members correspond to a plurality of the sliding support members respectively, and a spiral groove is provided on a side of the sliding support member away from the sliding disk;

[0035] A rotary drive member is rotationally connected to the sliding disk. A thread is provided on the rotary drive member. The thread portion is received in the spiral groove. The rotation of the rotary drive member drives the thread to rotate. The thread pushes the sliding support member to slide in the sliding groove.

[0036] The bracelet surface sand rolling machine provided above is designed with a sliding disk, a sliding support and a rotating drive member. The sliding support member is pushed to slide on the sliding disk by rotating the rotating drive member, so that the inner sides of bracelets of different sizes can abut against the sliding support member, thereby fixing the bracelet on the sliding support member. The bracelet is then driven to rotate rapidly by a power component, and a sanding knife is used to sand the bracelet while it rotates. In this way, the bracelet can be sanded quickly.

[0037] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0038] See also Figure 1-Figure 6 , an embodiment of the present application provides a bracelet surface sand rolling machine 100, including a power component 1, a sliding disk 2, a sliding support 3 and a rotating drive component 4, wherein one end of the sliding disk 2 is transmission-connected to the power component 1, and the other end is provided with a plurality of sliding grooves 21, and the plurality of sliding grooves 21 are arranged around the rotating axis of the sliding disk 2, the sliding support 3 is accommodated in the sliding groove 21, and is slidingly connected to the sliding groove 21, and the plurality of sliding support components 3 respectively correspond to the plurality of sliding support components 3 one by one, and a spiral groove 321 is provided on the side of the sliding support component 3 away from the sliding disk 2, the rotating drive component 4 is rotatably connected to the sliding disk 2, a thread 41 is provided on the rotating drive component 4, and the thread 41 is partially accommodated in the spiral groove 321, the rotation of the rotating drive component 4 drives the thread 41 to rotate, and the thread 41 pushes the sliding support 3 to slide in the sliding groove 21.

[0039] Specifically, the power assembly 1 is used to provide the power source required by the machine, and usually uses a motor as the power. The speed of the motor output is adjusted by a synchronous pulley to reach the speed required for processing, which is used to process the bracelet workpiece. The main function of the sliding plate 2 is to connect with the power assembly and place the sliding support 3, and drive the sliding support 3 to rotate around the rotating axis of the sliding plate 2, realizing the basis of power transmission and sand rolling process, and ensuring smooth and effective operation. The length direction of the sliding groove 21 opened on the sliding disk 2 is all pointing to the rotation axis of the sliding disk 2, so that the sliding support 3 can move outward or inward from the center of the sliding disk 2 along the radius of the sliding disk 2 when sliding along the length direction of the sliding groove 21. The purpose of setting multiple sliding grooves 21 around the sliding support 3 is to make the sliding support 3 evenly distributed on the sliding disk 2. The sliding support 3 is arranged in the sliding groove 21, and the sliding support 3 is in direct contact with the bracelet. When in contact, the sliding support 3 abuts against the inner wall of the bracelet, thereby fixing the bracelet workpiece on the sliding support 3. Multiple sliding supports 3 can abut against the bracelet from all directions, which increases the stability of the bracelet on the sliding support 3. By making the sliding support 3 slide in the sliding groove 21, the distance between the sliding support 3 and the central axis of the sliding disk 2 is adjusted to adapt to bracelets of various sizes. A thread 41 is provided on the rotating drive 4, and a spiral groove 321 is provided on the sliding support 3.

[0040] Furthermore, a thread 41 is provided on the rotary drive member 4, and a spiral groove 321 is provided on the sliding support member 3. The thread 41 is a spiral protrusion, and the spiral groove 321 is a spiral groove. Their geometric shapes and directions are designed to fit each other, so that the thread 41 can be nested in the spiral groove 321. When the rotary drive member 4 rotates, the thread 41 generates thrust on the spiral groove 321. Because the sliding support member 3 is slidably connected with the sliding groove 21, and the length direction of the sliding groove 21 is the radius direction of the sliding disk 2, the sliding support member 3 will slide along the length direction of the sliding groove 21 as the thread 41 rotates, and the pitch of the thread 41 is fixed. When the rotary drive member 4 rotates one circle, the displacement of all the sliding supports 3 is equal, and multiple rotary supports can move together with the rotation of the rotary drive member 4. Such a design can better support the inner wall of the bracelet.

[0041] In a specific example, the sliding support member 3 includes a sliding portion 32 located in the sliding groove 21 and an abutting portion 31 located at one end of the sliding portion 32 , and the spiral groove 321 is located on the sliding portion 32 .

[0042] Specifically, the sliding part 32 is used to slide in the sliding groove 21, and is usually made of a smooth and wear-resistant material, while the abutting part 31 is in direct contact with the bracelet and is made of a rougher and softer material. The sliding part 32 and the abutting part 31 are usually connected in a detachable manner. The purpose of this design is to facilitate the replacement of the abutting part 31. The sliding part 32 is relatively expensive, and the abutting part 31 requires a different shape to fit the shape of the bracelet. Therefore, designing the abutting part 31 and the sliding part 32 separately helps to cope with different processing environments. A specific abutting part 31 shape can be made for a specific bracelet without making a new sliding part 32, which also saves costs.

[0043] In a specific example, an anti-slip layer 311 is disposed on a side of the abutting portion 31 away from the sliding portion 32 .

[0044] Specifically, the anti-skid layer 311 is usually a layer of material or special treatment provided on the outer surface of the abutment portion 31, and this material or treatment method has a high friction coefficient. The main function of the anti-skid layer 311 is to increase the friction between the abutment portion 31 and the sliding groove 21. This is achieved by selecting a material with good friction properties or using a special surface treatment technology. By increasing the friction coefficient, the anti-skid layer 311 can improve the adhesion between the abutment portion 31 and the sliding groove 21, prevent accidental sliding or detachment during the sand rolling process, thereby ensuring the stability of the mechanical transmission.

[0045] In a specific example, the sliding groove 21 has a limiting portion 211 , and the limiting portion 211 is located on the sliding path of the sliding support member 3 to limit the sliding of the sliding support member 3 .

[0046] Specifically, the limiting portion 211 refers to a boss on the inner wall of the sliding groove 21. Due to the existence of the limiting portion 211, when the sliding support member 3 attempts to pass through the limiting portion 211, the limiting portion 211 will produce a physical blockage in the direction perpendicular to the movement of the sliding support member 3. This is like on the side of a mountain, the support member needs to climb or lower to pass over the boss. This vertical blocking effect limits the movement of the support member in the length direction of the sliding groove 21.

[0047] In a specific example, a hand-held portion 42 is provided on a side of the rotary driving member 4 away from the sliding plate 2 .

[0048] Specifically, the hand-held portion 42 is located on the side of the rotary drive member 4 away from the sliding disk 2. This means that the hand-held portion 42 is located on one side of the entire sand rolling machine structure, usually the side operated by the user. The hand-held portion 42 is usually designed to be ergonomically shaped to provide a comfortable hand-holding feeling. Such a design helps to reduce the user's hand fatigue and improve the convenience of operation. The operator pinches the hand-held portion 42 with his fingers and rotates the hand-held portion 42 to drive the rotary drive member 4 to rotate. Such a design provides the operator with a gripping portion on the rotary drive member 4, making it easier to rotate the rotary drive member 4.

[0049] In a specific example, a fastening screw 22 is provided on the sliding disk 2, and the rotating driving member 4 is located between the fastening screw 22 and the sliding disk 2, and the rotating driving member 4 is rotatably connected to the sliding disk 2 through the fastening screw 22, and the preload force between the sliding disk 2 and the rotating driving member 4 is controlled by the fastening screw 22.

[0050] Specifically, a fastening screw 22 is provided on the sliding disk 2, and the fastening screw 22 is usually provided in the central area, and acts as a fastener and a rotating shaft at the same time. The main function of the fastening screw 22 is to connect the sliding disk 2 and the rotating drive member 4, and to provide a means for adjusting the pre-tightening force between the sliding disk 2 and the rotating drive member 4. When the fastening screw 22 is screwed outward, the pre-tightening force between the sliding disk 2 and the rotating drive member 4 is reduced, so that the friction between the sliding disk 2 and the rotating drive member 4 is reduced, and the friction is reduced to a size that can drive the rotating drive member 4 to rotate relative to the sliding disk 2 by manpower, and then the rotating drive member 4 is rotated to adjust the position of the sliding support member 3. When the position of the sliding support member 3 is determined, the fastening screw 22 is tightened to increase the pre-tightening force between the sliding disk 2 and the rotating drive member 4, so that the sliding disk 2 and the rotating drive member 4 will not generate relative movement when the sliding disk 2 and the rotating drive member 4 are driven to rotate by the power assembly, ensuring that the bracelet will not be separated from the sliding support member 3 due to the change in the position of the sliding support member 3.

[0051] In a specific example, the distances between the plurality of sliding supports 3 and the fastening screws 22 are equal.

[0052] Specifically, the distances between the sliding supports 3 and the fastening screws 22 are equal, which means that the distances from one sliding support 3 to the next adjacent sliding support 3 and to the fastening screws 22 are consistent. This design helps to ensure that the positions of the sliding supports 3 in the sliding groove 21 are evenly distributed throughout the sliding system. This helps to balance the mechanical properties of the sliding system and provide more stable and uniform movement. By keeping the distances between the sliding supports 3 and the fastening screws 22 equal, the imbalance within the sliding system can be reduced. If the distances are inconsistent, some places may be subjected to greater forces while other places are subjected to smaller forces, affecting the stability of the system. This uniform distribution helps to improve the accuracy of the entire sliding system and ensure that the movement of each component during the sand rolling process is more uniform, thereby improving the consistency and controllability of the processing.

[0053] In a specific example, a connecting rod 23 is provided on a side of the sliding plate 2 away from the rotary driving member 4 , and the connecting rod 23 is used for transmission connection with the transmission assembly 11 .

[0054] Specifically, a connecting rod 23 is provided on the side of the sliding disk 2 away from the rotating drive member 4. The function of this connecting rod 23 is to connect the sliding disk 2 with the transmission assembly 11, and to transmit motion and force. The connecting rod 23 is used for transmission connection with the transmission assembly 11, which means that through this connecting rod 23, the sliding disk 2 can be powered by the transmission assembly 11 to achieve corresponding sliding motion, and the power on the connecting rod 23 is transmitted through the transmission assembly 11, so that the sliding disk 2 can perform rotational motion in the sliding groove 21.

[0055] In a specific example, the power assembly includes a transmission assembly 11 transmission-connected to the sliding disk 2 and a tachometer 12 disposed between the transmission assembly 11 and the sliding disk 2 .

[0056] Specifically, the tachometer 12 is a device for measuring the speed of a moving object. In this scenario, it is installed between the transmission assembly 11 and the sliding disk 2. The main function of the tachometer 12 is to measure the movement speed of the sliding disk 2. It can monitor the movement speed of the sliding disk 2 in real time through different sensors or technologies, such as photoelectric sensors, Hall effect sensors, etc. By measuring the movement speed of the sliding disk 2 in real time, the system can control the movement of the sliding disk 2 more accurately to ensure the stability and accuracy of the sand rolling process. The movement speed information provided by the tachometer 12 can be used as a feedback signal to adjust the output of the transmission assembly 11, thereby realizing real-time adjustment of the movement of the sliding disk 2.

[0057] In a specific example, a gasket 221 is disposed on the fastening screw 22 , and the gasket 221 is located between the fastening screw 22 and the rotary driving member 4 .

[0058] Specifically, the gasket 221 is a thin and strong sheet-like part, which is usually used to fill or adjust the gap of the mechanical device to provide additional support, shock absorption or adjustment. The gasket 221 is placed between the fastening screw 22 and the rotating drive member 4, that is, a space for the gasket 221 is formed between the two. This design is intended to provide a certain buffering and adjustment function between the fastening screw 22 and the rotating drive member 4 through the gasket 221. The presence of the gasket 221 can provide a certain buffering effect between the fastening screw 22 and the rotating drive member 4 to reduce the direct contact and friction between the two. The thickness and hardness of the gasket 221 can be selected as needed. By adjusting the characteristics of the gasket 221, the fastening force of the fastening screw 22 can be affected and adjusted. The presence of the gasket 221 helps to reduce the direct friction between the fastening screw 22 and the rotating drive member 4, thereby extending the service life of the two.

[0059] The above is only an implementation method of the present application. It should be pointed out that a person skilled in the art can make improvements without departing from the inventive concept of the present application, but these improvements are within the scope of protection of the present application.
