Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of musical instrument production, specifically to a marking machine for saxophone production. Background Technology

[0002] In the saxophone manufacturing industry, the marking process is a crucial step in identifying the instrument and facilitating brand traceability. Brand logos, model parameters, production numbers, and other information must be marked on the saxophone body, keypad, and other parts. The clarity and positional accuracy of the markings directly affect the instrument's brand recognition and product standardization. As a specialized marking tool, the structural adaptability and operational stability of saxophone marking machines directly determine marking quality and production efficiency. With the increasing refinement and branding of saxophones, the shortcomings of traditional marking equipment have become increasingly apparent: existing saxophone marking machines generally adopt a circular design and rely on handheld operation. When marking irregularly shaped curved surfaces of saxophones, multiple machine position changes are required, making operation cumbersome and prone to marking misalignment, failing to meet the demands for precise and efficient marking. Traditional circular marking machines integrate the marking head and operating handle into one unit. While the circular body makes it easy to hold, the marking range is limited to small flat areas. Saxophones often have irregular curved surfaces to be marked, and different markings (such as logos and numbers) are distributed in different locations. Operators must repeatedly adjust the angle and position of the marking machine while holding it, requiring recalibration after each change. This not only prolongs marking time but also makes the markings prone to shifting or tilting due to slight hand tremors. Furthermore, the circular structure lacks positioning aids adapted to the curved surface of the saxophone, making it difficult to stably adhere to the tube during marking, resulting in uneven marking depth. This is especially problematic on metal saxophone surfaces, where misaligned or uneven markings severely affect the appearance quality. Therefore, developing a marking machine that is compatible with the irregular structure of saxophones, does not require repeated position changes, and is stable in operation has become an urgent need to improve the marking accuracy and production efficiency of saxophones. Utility Model Content

[0003] To overcome the above-mentioned defects, the embodiments of this disclosure provide a marking machine for saxophone production, which solves the technical problems of existing saxophone marking machines generally adopting a circular structure design and relying on hand-held operation. When marking irregular curved surfaces of saxophones, the machine position needs to be changed multiple times, which is cumbersome and prone to marking misalignment.

Both ends of the mounting bracket are bent upwards at 90°. Both sides of the mounting bracket are horizontally connected to support studs via threads. One end of each support stud is rotatably fitted with a clamping disc. The bottom of the movable block is horizontally slidably connected to the surface of the base plate via a slide rail.

[0005] According to another aspect, in at least one embodiment of the present invention, the smoke removal assembly includes a pair of fixing rods, each fixing rod being fixed to the top of the main frame, and each fixing rod having an air intake pipe fitted onto its lower end, with a cavity plate provided at one end of the air intake pipe.

[0006] As a further technical solution, the cavity plates are fixedly connected, a dust suction port is provided on the bottom surface of the cavity plate, a suction fan is provided at one end of the bottom plate surface, a telescopic pipe is provided at the suction end of the suction fan, and a T-shaped pipe is provided at the upper end of the telescopic pipe.

[0007] As a further technical solution, the three-way pipe is connected to a pair of the air intake pipes, and a purification filter element is horizontally inserted and connected to the outer side of the base plate. The purification filter element is inserted and connected to the exhaust end of the suction fan.

[0008] According to another aspect, in at least one embodiment of the present invention, the height adjustment component includes a vertical stud, which is rotatably connected between the main frame and the base plate. A pair of guide posts are connected between the main frame and the base plate. A lifting frame is vertically slidably connected to the guide posts.

[0021] like Figures 1-3 As shown, it illustrates a marking machine for saxophone production according to an embodiment of the present disclosure, comprising: The base plate 1 and the main frame 2 are fixed to the surface of the base plate 1. The laser head 3 and the height adjustment component 7 are provided. The laser head 3 is mounted on the main frame 2, and the height adjustment component 7 is mounted on the base plate 1 and the main frame 2. Smoke removal component 6, wherein the smoke removal component 6 is disposed on the base plate 1; The movable block 4 and the positioning component 5 are provided. The movable block 4 is horizontally slidably connected to the surface of the base plate 1, and the positioning component 5 is disposed on the movable block 4. The positioning component 5 includes a mounting bracket 5-1, which is fixed on the movable block 4. Both ends of the mounting bracket 5-1 are bent upward at 90°. Both sides of the mounting bracket 5-1 are horizontally connected to support studs 5-2 by threads. One end of each support stud 5-2 is rotatably fitted with a clamping plate 5-3. The bottom of the movable block 4 is horizontally slidably connected to the surface of the base plate 1 by a slide rail.

[0022] In some examples, to achieve stable fixation and flexible position adjustment of the saxophone during laser marking and to avoid misalignment of the marking caused by instrument displacement or angular deviation during marking, a positioning component 5 is designed. This component includes a mounting bracket 5-1 on the moving block 4 with both ends bent upwards at 90° to form a symmetrical clamping support structure, providing a stable mounting reference for the saxophone. The mounting bracket 5-1 has support studs 5-2 connected horizontally on both sides by threads, and the extension length can be adjusted by screwing, thereby pushing the clamping plate 5-3, which is mounted on one end, closer to the saxophone, achieving adaptive clamping from both sides of the instrument. The rotation design of the clamping plate 5-3 ensures that it can fit the curved surface of the saxophone, avoiding rigid contact that could damage the instrument's surface. At the same time, the self-locking characteristic of the threads maintains stable clamping force, preventing the instrument from loosening during marking. The bottom of the movable block 4 is horizontally connected to the surface of the base plate 1 via a slide rail, forming a horizontal moving structure. The operator can push the movable block 4 to make the saxophone slide smoothly along the slide rail, adjust the relative position of the instrument and the laser head 3, so that the laser head 3 can be accurately aligned with the marking area.

[0023] The precise fit of the slide rails reduces movement gaps, ensuring the saxophone's posture remains stable without wobbling or shifting during position adjustments. The symmetrical distribution design of the support studs 5-2 ensures that the clamping force is evenly applied to both sides of the saxophone, preventing deformation of the instrument due to unilateral force. The surface of the clamping disc 5-3 can be designed with an anti-slip structure to further enhance friction with the saxophone and improve clamping stability.

[0024] During operation, place the saxophone between the mounting brackets 5-1, tighten the support studs 5-2 to clamp the instrument with the clamping discs 5-3, and push the moving block 4 to adjust it to the marking position. Then, start the laser head 3 to perform the marking operation. The bidirectional clamping ensures a stable fixation, the horizontal sliding improves adaptability, and the coordinated operation of all components achieves precise positioning of the saxophone, meeting the marking needs of multiple parts.

[0025] like Figures 1-3As shown in the figure, the smoke removal assembly 6 in this embodiment includes a pair of fixing rods 6-1, both of which are fixed to the top of the main frame 2. Each fixing rod 6-1 has a suction pipe 6-2 fitted onto its lower end. A cavity plate 6-3 is provided at one end of each suction pipe 6-2. The cavity plates 6-3 are fixedly connected to each other. A dust suction port 6-4 is provided on the bottom surface of each cavity plate 6-3. A suction fan 6-5 is provided at one end of the surface of the base plate 1. A telescopic pipe 6-6 is provided at the suction end of the suction fan 6-5. A three-way pipe 6-7 is provided at the upper end of the telescopic pipe 6-6. The three-way pipe 6-7 is connected to the pair of suction pipes 6-2. A purification filter element 6-8 is horizontally inserted and connected to the outer side of the base plate 1. The purification filter element 6-8 is inserted and connected to the exhaust end of the suction fan 6-5.

[0026] In some examples, in order to efficiently handle the fumes generated during laser marking of saxophones and prevent the fumes from spreading and polluting the processing environment or endangering the health of operators, a fume extraction component 6 is designed. This component includes a pair of fixed rods 6-1 fixed at the top of the main frame 2 to provide vertical installation support for the suction pipe 6-2, ensuring the stability of the suction pipe 6-2. The bottom surface of the cavity plate 6-3 connected to one end of the suction pipe 6-2 has a dust suction port 6-4, and the cavity plates 6-3 are fixedly connected to form an integral suction structure that can cover the space above the laser marking area, so that the fumes generated during marking can quickly enter the suction pipe 6-2 through the dust suction port 6-4, preventing the fumes from spreading to the surroundings. The suction fan 6-5 at one end of the base plate 1 provides power for the flow of flue gas. Its suction end is connected to the tee pipe 6-7 through the telescopic pipe 6-6. The tee pipe 6-7 is connected to a pair of suction pipes 6-2 to form a flue gas delivery channel. When the suction fan 6-5 is started, it draws the flue gas in the suction pipes 6-2 through the telescopic pipe 6-6 and the tee pipe 6-7. The telescopic feature of the telescopic pipe 6-6 is adapted to the position adjustment of the equipment components to avoid damage to the pipes. The purification filter element 6-8 inserted on the outside of the base plate 1 is connected to the exhaust end of the suction fan 6-5. It can filter and purify the sucked flue gas, remove dust particles and harmful components, and ensure that the purified gas meets the emission standards, thus reducing environmental pollution.

[0027] The integrated design of the cavity plate 6-3 ensures that the dust inlets 6-4 are evenly distributed, improving the efficiency of smoke capture; the sealed connection of the air intake pipe 6-2 prevents smoke leakage, and the plug-in design of the purification filter element 6-8 facilitates regular replacement and reduces maintenance costs.

[0028] During operation, the fumes generated by laser marking enter the suction pipe 6-2 through the dust inlet 6-4, and are then transported to the purification filter element 6-8 by the exhaust fan 6-5, where they are purified before being discharged. Directional suction ensures thorough fume collection, and purification filtration achieves environmentally friendly emissions. All components work together to create a clean and safe marking environment, meeting production requirements.

[0029] like Figures 1-3 As shown in the figure, the height adjustment component 7 in this embodiment includes a vertical stud 7-1, which is rotatably connected between the main frame 2 and the base plate 1. A pair of guide posts 7-2 are connected between the main frame 2 and the base plate 1. A lifting frame 7-3 is vertically slidably connected to the guide posts 7-2. The lifting frame 7-3 is connected to the vertical stud 7-1 by a threaded connection. The laser head 3 is installed at the bottom of the lifting frame 7-3.

[0030] In some examples, in order to achieve precise adjustment of the vertical height of the laser head 3, adapt to the height requirements of different specifications or different marking parts, and avoid blurry marking or collision of the laser head 3 with musical instruments due to improper height, a height adjustment component 7 is designed. This component includes a vertical stud 7-1 that rotatably connects the main frame 2 and the base plate 1 as the core of the lifting drive. It and the lifting frame 7-3 are connected by threads to form a lifting transmission structure. When the vertical stud 7-1 is rotated, the lifting frame 7-3 is driven to slide vertically along the guide post 7-2 through the thread transmission, thereby adjusting the height of the laser head 3 installed at the bottom of the lifting frame 7-3. The self-locking characteristic of the thread transmission ensures that the lifting frame 7-3 can be stably stopped at the target height after adjustment, avoiding height deviation due to gravity sliding.

[0031] A pair of guide columns 7-2 between the main frame 2 and the base plate 1 are vertically slidably fitted with the lifting frame 7-3, providing symmetrical guide support for the lifting frame 7-3, ensuring that the lifting frame 7-3 remains horizontal during the lifting process without tilting or shaking, thereby ensuring the stability of the marking reference of the laser head 3 and avoiding laser marking position deviation caused by the tilt of the lifting frame 7-3.

[0032] The high-strength design of the guide column 7-2 can withstand the weight of the lifting frame 7-3 and the laser head 3, preventing component deformation and extending the service life of the equipment. The rotation drive of the vertical stud 7-1 allows operators to precisely control the lifting speed and height, meeting the needs of fine height adjustments in different marking scenarios; the stable connection between the lifting frame 7-3 and the laser head 3 ensures that the laser head 3 does not loosen during lifting, guaranteeing marking accuracy.

[0033] During operation, depending on the saxophone specifications or marking requirements, rotating the vertical stud 7-1 drives the lifting frame 7-3 and laser head 3 to rise and fall. After adjusting to the appropriate height, the laser head 3 can be started for marking. The threaded drive ensures precise height adjustment, and the guide column 7-2 ensures smooth lifting. The coordinated operation of all components enables flexible adaptation of the laser head 3 height, meeting diverse marking needs and improving the equipment's versatility and marking quality.

[0034] For example, such as Figure 1 As shown, the pair of cavity plates 6-3 are tilted in opposite directions and are located on both sides of the laser head 3.

[0035] In some examples, the design of a pair of cavity plates 6-3 tilted in opposite directions and located on both sides of the laser head 3 can form a bidirectional converging smoke capture area. The smoke generated by laser marking will diffuse in all directions, and the tilted cavity plates 6-3 can guide the smoke to converge towards the dust collection port 6-4 through the inclined surface. At the same time, the layout on both sides can cover the left and right sides of the marking area of ​​the laser head 3, preventing the smoke from escaping from the side.

[0036] For example, such as Figure 3 As shown, one of the clamping discs 5-3 is a cylindrical structure with a funnel-shaped opening.

[0037] In some examples, one of the clamping plates 5-3 is a cylindrical structure with a flared opening, which can accommodate the irregular contours of the saxophone end (such as the mouthpiece interface and bell mouth). The saxophone end is mostly an arc-shaped structure with a gradually changing diameter. The flared opening can form a wraparound support from the outside of the end, increasing the contact area with the instrument and avoiding the problem of excessive local force caused by the traditional flat clamping plate 5-3.

[0038] For example, such as Figure 1 As shown, handles 8 are provided on all side surfaces of the movable block 4.

[0039] In some examples, the handle 8 on the side surface of the movable block 4 provides a convenient point of force for the operator to adjust the position of the movable block 4. Saxophone marking requires frequent pushing of the movable block 4 to adjust the marking area. The ergonomic design of the handle 8 allows the operator to easily push the movable block 4 with one hand, which is less strenuous than directly pushing the top of the movable block 4 and allows for precise control of the movement speed, preventing the movable block 4 from wobbling due to uneven force application.

[0040] In actual use: Place the saxophone between the mounting brackets 5-1 of the positioning component 5, and screw on the support studs 5-2 on both sides of the mounting bracket 5-1 to clamp the saxophone from both sides. One of the flared clamping discs 5-3 is adapted to the contour of the instrument end to ensure a stable fixation. Hold the handle 8 on the side surface of the moving block 4 and push the moving block 4 to slide horizontally along the slide rail of the base plate 1 to adjust the saxophone to the marking area below the laser head 3. Activate the height adjustment component 7, rotate the vertical stud 7-1 to drive the lifting frame 7-3 to slide vertically along the guide column 7-2, and adjust the laser head 3 to the appropriate marking height. Turn on the exhaust fan 6-5 of the smoke removal component 6. The smoke generated by the laser head 3 during marking is drawn in through the dust inlets 6-4 of the inclined cavity plates 6-3 on both sides, and transported to the purification filter element 6-8 through the suction pipe 6-2, the three-way pipe 6-7 and the telescopic pipe 6-6, and discharged after filtration. During the marking process, the position of the saxophone can be adjusted by moving block 4 to complete the marking of different areas. The entire process does not require repeated disassembly or switching of equipment, thus achieving precise marking of irregular curved surfaces of the saxophone.
