[0049] Example 1

[0050] This embodiment achieves automatic feeding and pushing of the shell to be marked by driving the component to automatically reciprocate between the starting position and the marking position, thus improving production efficiency. By forming multiple receiving spaces in the supporting component, the shell marking device can process multiple shells to be marked simultaneously, shortening the production cycle and effectively improving marking efficiency. The specific solution is as follows:

[0051] As per the instruction manual Figure 1-6 As shown, this embodiment provides a shell marking device, including a processing platform 1, a bearing component 2, a driving component 3, and a pushing component 4; the processing platform 1 is defined with a preset starting position a and a preset marking position b;

[0052] The supporting component 2 is fixedly installed on the processing platform 1 near the starting point a, facilitating rapid loading of the shells. The supporting component 2 has at least two receiving spaces 20 arranged horizontally inside to accommodate the shells to be marked. Optionally, there can be two, three, or more receiving spaces 20, enabling the shell marking device to process multiple shells simultaneously, effectively improving marking efficiency. Furthermore, the bottom of the supporting component 2 has a discharge port 21 that communicates with each receiving space 20.

[0053] The pushing component 4 is slidably disposed on the processing platform 1 and located below the discharge port 21. The driving component 3 is connected to the pushing component 4. The driving component 3 is used to drive the pushing component 4 to reciprocate between the starting position a and the marking position b. Specifically, when the driving component 3 drives the pushing component 4 from the starting position a to the marking position b, it pushes the shell to be marked located at the discharge port 21 to the marking position b; and after marking is completed, it drives the pushing component 4 to return from the marking position b to the starting position a.

[0054] Whenever a shell to be marked slides out of the discharge port 21, the push component 4, driven by the drive component 3, quickly and steadily pushes the shell from the starting position a to the marking position b. After pushing the shell to the marking position b, the push component 4 resets under the drive of the drive component 3, preparing for the next pushing operation, thus ensuring the continuity and efficiency of the production line.

[0055] In an optional embodiment, as shown in the appendix to the specification... Figure 3 Included with instruction manual Figure 5 As shown, in order to further improve the stability and operating accuracy of the shell marking device, the shell marking device also includes a guide component 5. The guide component 5 extends along the direction from the starting position a to the marking position b, providing clear guidance and support for the movement of the pushing component 4.

[0056] The driving component 3 is driven and connected to the guiding component 5. The side of the guiding component 5 away from the driving component 3 is connected to the pushing component 4. The guiding component 5 is used to drive the pushing component 4 to reciprocate between the starting position a and the marking position b under the drive of the driving component 3.

[0057] The guide component 5 provides a stable motion trajectory for the push component 4, effectively reducing operational instability caused by vibration or offset, and ensuring long-term stable operation of the device. Through the guide component 5, the push component 4 can move accurately along a preset path, achieving precise positioning of the outer shell between the starting position a and the marking position b, improving the accuracy and consistency of the marking operation, and thus increasing the marking efficiency of the outer shell marking device.

[0058] In an optional embodiment, the guide assembly 5 includes a guide rail 50 and a slider 51 that slides with the guide rail 50, as shown in the appendix to the specification. Figure 3 Included with instruction manual Figure 5 As shown, the guide rail 50 is set in the same direction as the moving direction of the push component 4, and similarly, the slider 51 moves in the same direction as the moving direction of the push component 4.

[0059] In an optional embodiment, two sets of guide rails 50 are arranged in parallel, located on both sides of the pushing component 4, and each set of guide rails 50 has a slider 51 slidably engaged on it. The two sets of parallel guide rails 50 are symmetrically arranged on both sides of the pushing component 4, forming a double linear guide rail with the slider 51. The two guide rails can share the pushing load, avoiding jamming caused by force on one side.

[0060] The drive assembly 3 drives the slider 51, and the side of the slider 51 away from the drive assembly 3 is connected to the push assembly 4. Driven by the drive assembly 3, the slider 51 drives the push assembly 4 to reciprocate along the guide rail 50. The power generated by the drive assembly 3 is transmitted to the slider 51, driving it to move along the trajectory of the guide rail 50. The side of the slider 51 away from the drive assembly 3 is connected to the push assembly 4, thus converting the linear motion of the slider 51 into synchronous movement of the push assembly 4. The combined design of the guide rail 50 and the slider 51 provides a stable motion trajectory and support for the push assembly 4, effectively reducing operational instability caused by vibration or offset, and ensuring long-term stable operation of the device.

[0061] In an optional embodiment, as shown in the appendix to the specification... Figure 4 As shown, the supporting component 2 includes a supporting part 22 and a blocking part 23. The supporting part 22 is provided with the accommodating space 20. The blocking part 23 is connected to the supporting part 22 for opening or closing the accommodating space.

[0062] Optionally, the specific dimensions of the support portion 22 and the receiving space 20 can be adjusted according to the dimensions of the shell to be marked, ensuring that the shell to be marked can be stably placed therein. If the dimensions of the support portion 22 and the receiving space 20 are too large, the shell to be marked will wobble; if the dimensions of the support portion 22 and the receiving space 20 are too small, the shell to be marked cannot be placed inside.

[0063] In some embodiments, the blocking part 23 may be a rotating door structure rotatably connected to the supporting part 22. When the operator needs to add the shell to be marked into the receiving space 20, the rotating door can be opened to quickly put the shell to be marked into the receiving space 20; after the addition is completed, the operator closes the rotating door, which can effectively prevent the shell to be marked from falling out of the receiving space 20 during subsequent operations (such as vibration or movement during the marking process).

[0064] In one optional implementation, the edge of the rotating door can adopt a streamlined arc transition, with the curvature matching the shape and center of gravity distribution of the shell to be marked. When the rotating door begins to close, the arc edge will first contact the side wall of the shell to be marked. According to the principle of force decomposition, the force generated at the moment of contact can be decomposed into a horizontal corrective force and a slight vertical pressure. The horizontal corrective force can cleverly push the shell to be marked to translate and rotate within the receiving space 20, gradually adjusting it to the preset standard position; the slight vertical pressure plays an auxiliary fixing role, preventing excessive shaking of the shell during the alignment process.

[0065] In an optional embodiment, the surface of the support portion 22 may also be provided with a positioning guide groove, which is linked with the arc-shaped structure of the rotating door edge. When the rotating door is closed, the bottom or side of the shell to be marked will slide along the guide groove under the action of the corrective force, further ensuring the accuracy and stability of the alignment direction. In this way, when the rotating door is fully closed, the shell to be marked will be in the ideal position, laying a solid foundation for subsequent marking operations, greatly improving marking efficiency and product consistency, and reducing the defect rate caused by shell position deviation.

[0066] In an optional embodiment, to improve the connection stability and ease of operation between the support portion 22 and the sealing portion 23, the support assembly 2 further includes a magnetic attraction mechanism 24. The magnetic attraction mechanism 24 includes a first magnetic attractor 240 and a second magnetic attractor 241. The first magnetic attractor 240 is disposed on the end region of the support portion 22 near the sealing portion 23, and the second magnetic attractor 241 is correspondingly disposed on the mating region of the sealing portion 23 near the support portion 22. The first magnetic attractor 240 and the second magnetic attractor 241 are arranged with opposite magnetic poles, forming a magnetic attraction when the sealing portion is closed.

[0067] When the sealing part 23 is in the closed state, a magnetic attraction force is generated between the first magnetic attractor 240 and the second magnetic attractor 241, forming a stable closing holding force. During equipment operation, the magnetic attraction force can effectively suppress unintended opening caused by mechanical vibration or instantaneous impact. At the same time, the magnetic opening and closing mechanism does not require precise alignment operation, and can achieve quick opening and closing with one hand, greatly improving the convenience of operation.

[0068] The first magnetic attractor 240 and the second magnetic attractor 241 can be permanent magnets, electromagnets, etc.

[0069] In an optional embodiment, the carrier component 2 further includes partitions 25, vertically disposed between adjacent receiving spaces 20, with the bottom of each partition 25 extending to a position flush with the discharge port 21. The partitions 25 not only serve as spatial dividers but also provide precise positioning for the shell to be marked, ensuring stable positioning of the shell during the carrying process.

[0070] Optionally, the size and shape parameters of the partition 25 can be customized according to the geometric features of the shell to be marked and the structural parameters of the receiving space 20. When the shell to be marked is placed in the receiving space 20, the partition 25, through its limiting structure, forms a three-dimensional constraint in the horizontal, longitudinal, and vertical dimensions of the horizontal plane, effectively suppressing the degree of freedom of the shell, ensuring that it maintains an absolutely stable posture during the conveying process, and preventing abnormal phenomena such as displacement and sway caused by inertia or vibration.

[0071] Meanwhile, to address the potential initial angular deviation of the outer casing during placement, the partition 25 can be designed using an elastic composite material and a streamlined structure. When the outer casing to be marked comes into contact with the partition 25, the elastic deformation characteristics of the partition 25 can absorb impact energy. Simultaneously, its pre-fabricated guide slope or curved surface contour forms a dynamic coupling with the edge of the outer casing, applying a progressive correction effect to the outer casing through the elastic restoring force generated by micro-deformation. This process, through the synergistic effect of material mechanics and geometric constraints, allows the outer casing to automatically complete angular correction without external force intervention, achieving precise spatial orientation.

[0072] Through the dual mechanism of physical limiting and elastic correction, not only is the efficiency bottleneck caused by manual adjustment in traditional processes eliminated, but the positioning accuracy of the shell is also improved, thereby enhancing the automation level of the production line and product consistency, laying the foundation for subsequent high-precision marking operations.

[0073] In an optional embodiment, to further improve the processing accuracy and stability of the shell marking device, the shell marking device further includes a limiting component 6. The limiting component 6 is disposed on the processing platform 1 in the area near the marking position b, so as to limit the shell to be marked at the marking position b, and prevent it from being displaced due to factors such as vibration, airflow or operation error during the marking process, thereby ensuring that the marking pattern or text can be accurately and clearly printed on the designated position of the shell.

[0074] Optionally, the limiting component 6 can be flexibly adjusted according to the shape, size, and marking process requirements of the shell to be marked. For example, the limiting component can achieve precise changes in position and angle through transmission components such as slide rails and lead screws to adapt to the limiting requirements of shells of different specifications.

[0075] In an optional embodiment, the shell marking device further includes a transmission assembly 7, one side of which is drivenly connected to the drive assembly 3, and the other side of which is drivenly connected to the push assembly 4. The transmission assembly 7 enables stable power transmission between the drive assembly 3 and the push assembly 4, resulting in smoother and more coordinated operation of the entire shell marking device, effectively improving the overall performance and working efficiency of the device.

[0076] In an optional embodiment, the transmission assembly 7 may include transmission elements such as gears, chains, and belts to convert and distribute the power from the drive mechanism 3 and transmit it to the push assembly 4. Upon receiving the power from the transmission assembly 7, the push assembly 4 pushes the shell to be marked accurately to the marking position, laying a solid foundation for subsequent marking operations. Through the power transmission of the transmission assembly 7, the overall operation of the shell marking device is smoother and more coordinated, effectively improving the overall performance and working efficiency of the device.

[0077] In an optional embodiment, as shown in the appendix to the specification... Figure 1 Included with instruction manual Figure 6 As shown, the shell marking device also includes a fixing component 8. One side of the fixing component 8 is connected to the bearing component 2, and the other side of the fixing component 8 is connected to the processing platform 1. The bearing component 2 is fixedly connected to the processing platform 1 through the fixing component 8. During the operation of the device, it can effectively reduce the loosening and displacement of components caused by vibration, impact and other factors, improve the stability and reliability of the device, and reduce the probability of equipment failure.

[0078] The pushing component 4 is located between the processing platform 1 and the fixing component 8.

[0079] In an optional embodiment, the fixing component 8 has an opening 80 that matches the discharge port 21. The opening 80 allows the shell to be marked in the carrying component 2 to fall out from the discharge port 21 and the opening 80 in sequence, and be pushed by the pushing component 4 to the preset processing position to realize the marking operation, optimize the overall production process, and improve production efficiency.

[0080] In an optional embodiment, the fixing component 8 may include a support plate vertically disposed on the processing platform 1, the upper end of the support plate being fixedly connected to the bearing component 2 and the lower end being fixedly connected to the processing platform 1, and the pushing component 4 being located between the support plate and the bearing component 2.

[0081] The support plate has a through hole corresponding to the discharge port, and the size of the through hole is larger than the size of the discharge port.

[0082] The fixed component 8 forms a rigid support structure through a vertically arranged support plate. Its upper end is fixedly connected to the load-bearing component 2, and its lower end is fixedly connected to the processing platform 1, forming a stable triangular force transmission path. This effectively resists the lateral torque generated when the pushing component 4 moves, preventing the load-bearing component 2 from shifting or vibrating. The through-hole size on the support plate is larger than the discharge port, forming a non-contact avoidance structure to prevent interference between the outer casing and the support plate during conveying, ensuring a smooth discharge path.

[0083] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model.
