[0001] The invention relates to the technical field of marking, and in particular to a powder spray head marking device. Background Art

[0002] In the metal processing industry, accurate marking of products is a key process, especially in automated production lines, where the requirements for marking accuracy and efficiency are getting higher and higher. Traditional marking methods often rely on manual operation, which is not only inefficient but also difficult to ensure accuracy. With the development of industrial automation technology, powder spray marking devices have gradually emerged. They form clear and accurate markings on the metal surface by spraying powder, greatly improving production efficiency and marking accuracy.

[0003] However, the existing powder spray head marking device still has some shortcomings in structural design. For example, the position adjustment of the spray head is not flexible enough to meet the marking requirements of complex metal products; the supply and injection control of the powder material is not precise enough, which easily leads to unstable marking quality. Therefore, the development of a powder spray head marking device with reasonable structure, simple operation and high marking accuracy has become an urgent problem to be solved in the metal processing industry. Summary of the invention

DETAILED DESCRIPTION

[0027] The present invention is described below with specific embodiments, but they are not intended to be limiting of the invention.

[0028] Embodiment 1

[0029] like Figure 1-Figure 7 As shown, in this embodiment, a powder spray head marking device is provided, including a conveying device 1, a support frame and a spray head. The conveying device 1 is provided with a conveying channel for moving the product to be marked. In this embodiment, the product to be marked discussed specifically refers to metal plates or block metal components. In order to realize the automated conveying of these products, a plurality of rollers are arranged in the conveying channel. These rollers not only serve as the supporting surface of the product, but also effectively promote the product placed thereon to move smoothly along the conveying channel through their own rotational movement. In order to realize the continuous rotation of the roller, a driving device is integrated on the conveying device 1, and the device usually uses a motor as a power source, which is based on the wide application and maturity of motor drive technology in the field of industrial automation. It is worth noting that although the rotation mechanism of the roller is a common component in the prior art and is not the core innovation of the present invention, its ingenious application in this embodiment provides a solid technical support for the efficient and stable conveying of metal products. Therefore, the focus of the present invention is not to elaborate on the specific implementation method of the rotation of the roller.

[0030] The support frame is a double-layer structure, including a bottom frame 2 and a top frame 3. The top frame 3 is slidably installed above the bottom frame 2. The core function of this support frame is to firmly support the nozzle for spraying powder, ensuring that it can accurately and stably apply powder to the metal product to be scribed during operation. The design of the support frame is divided into two parts: the bottom frame 2 and the top frame 3. The bottom frame 2, as the cornerstone of the entire structure, is installed on the conveying device 1 in a reliable fixing manner, providing a solid support foundation for the entire support frame. The top frame 3 is designed to be more flexible. It can slide along the preset track of the bottom frame 2 and move up and down above the bottom frame 2.

[0031] The end of the nozzle is the discharge port. The nozzle includes a shell 4 and an inner pin 5. The shell 4 is connected to the bottom frame 2, and the inner pin 5 is connected to the top frame 3. The sliding connection design between the bottom frame 2 and the top frame 3 gives them two different working states: a separated state and a merged state. In the initial state, the inner pin 5 (as a movable part inside the nozzle) is closely connected to the shell 4 (the main part of the nozzle, including the discharge port), ensuring that the powder can be smoothly ejected from the storage cavity 401 through the discharge port. When the bottom frame 2 and the top frame 3 are in a separated state, the up and down movement of the top frame 3 will pull the inner pin 5 to slide inside the shell 4. In this process, the inner pin 5 will slide outward for a preset distance, resulting in a certain gap between it and the discharge port. The generation of this gap effectively interrupts the spraying of the powder. On the contrary, when the bottom frame 2 and the top frame 3 re-enter the merged state, the reset action of the top frame 3 will drive the inner pin 5 to slide in the opposite direction until its end is in close contact with the discharge port again. The sliding connection between the bottom frame 2 and the top frame 3 and the ingenious coordination between the inner pin 5 and the shell 4 enable the nozzle to achieve precise control and adjustment of powder injection, meeting the diverse needs during the metal product scoring process. A storage chamber 401 for storing powder is provided inside the shell 4, and the discharge port is connected to the storage chamber 401. Under the action of gravity, the powder inside the storage chamber 401 accumulates at the bottom of the storage chamber 401. When the end of the inner pin 5 is separated from the discharge port, the powder will fall downward.

[0032] Among them, the upper end of the inner pin 5 extends out of the storage chamber 401 and is fixed with a driving gear 11. A linkage mechanism for driving the driving gear 11 to rotate is installed on the top frame 3 (the linkage mechanism includes a second slide 8, a driven slide 9 and a fixed block 10). The linkage mechanism can drive the inner pin 5 to rotate through the driving gear 11. The discharge port is a cylindrical hole. The end of the inner pin 5 is fixed with a spiral body 15 arranged inside the discharge port. When the inner pin 5 component slides upward, the spiral structure at its end will rotate accordingly. This rotation action effectively pushes the powder falling from the storage chamber 401 downward step by step. When the spiral 15 is in a non-rotating state, due to the close fit of the contact parts between it and the inner wall of the discharge port, this design ensures that even if the spiral 15 stops rotating, the powder will not continue to slide down spontaneously, thereby achieving precise control of the flow of powder. A sphere 14 is fixed at the connection between the spiral 15 and the end of the inner pin 5. The sphere 14 is located inside the storage chamber 401. The diameter of the sphere 14 is larger than the diameter of the discharge port. The sphere 14 is designed to block the entrance of the discharge port. When the top frame 3 and the bottom frame 2 are in a tightly combined state, the sphere 14 is located exactly at the discharge port, forming an effective seal, thereby preventing the powder from passing through. In this closed state, even if the inner pin 5 rotates, the powder cannot continue to fall down due to the blocking effect of the sphere 14 on the discharge port, ensuring the sealing of the system and the stable storage of the powder.

[0033] Embodiment 2

[0034] like Figure 1-Figure 7 As shown, based on the first embodiment, this embodiment provides a driving method for the inner pin 5, which is as follows:

[0035] The first slideway 7 is slidably installed inside the chassis 2, and the slider 6 is slidably installed inside the first slideway 7. The sliding directions of the first slideway 7 and the slider 6 are perpendicular to each other, forming an X direction and a Y direction on the horizontal plane. The housing 4 is fixed on the slider 6, and the slider 6 can drive the housing 4 to slide arbitrarily inside the chassis 2. The slider 6 slides on the horizontal plane formed by the X axis and the Y axis. The sliding mechanism of the slider 6 can be a cylinder drive and a screw drive. In the cylinder drive mode, the cylinder is firmly installed on the chassis 2 and the first slideway 7. The output end of the cylinder is connected to the first slideway 7 and the slider 6 respectively. Through the piston movement of the cylinder, the first slideway 7 and the slider 6 can be directly driven to move relative or coordinated on the horizontal plane. In the screw drive mode, the rotatable screw is cleverly embedded in the internal structure of the chassis 2 and the first slideway 7. This screw runs through the first slideway 7 and the slider 6 at the same time, forming a mechanical connection. When the screw is rotated by an external force, the interaction between its thread and the slider 6 and the thread groove inside the first slide 7 can cause the first slide 7 and the slider 6 to slide inside the base frame 2 and the first slide 7 respectively, thereby realizing the displacement control of the slider 6. The installation method of the screw and the cylinder is the existing technology and is not the innovation of the present invention, so it is not explained in detail in the present invention.

[0036] The second slideway 8 is slidably installed inside the top frame 3. The second slideway 8 is slidably installed on the first slideway 7 through a slide rod. The second slideway 8 is designed to slide vertically up and down only above the first slideway 7. Therefore, when the first slideway 7 slides, the second slideway 8 will move vertically accordingly.

[0037] A fixed block 10 is slidably installed on the second slide 8, and a driven slide 9 is fixed on the fixed block 10. The driven slide 9 is provided with teeth inside, and the gear 11 meshes with the teeth on the driven slide 9. When the slider 6 and the fixed block 10 slide, the gear 11 will also slide inside the driven slide 9. During the sliding process of the gear 11, the gear 11 will drive the inner pin 5 connected thereto to rotate.

[0038] The shell 4 is provided with a feed port, which is connected to the external powder feeding device through a pipeline. A feed port is specially designed on the shell 4 of the nozzle, and this feed port is the key channel for the powder to enter the internal storage chamber 401 of the nozzle. In order to ensure that the powder can be continuously and stably supplied to the inside of the nozzle, the feed port is closely connected to the external powder feeding device through a special pipeline. In this way, when the powder feeding device starts working, the powder will flow smoothly into the storage chamber 401 of the nozzle along the pipeline, providing sufficient raw materials for the subsequent scribing process.

[0039] Embodiment 3

[0040] like Figure 1-Figure 7As shown, based on the first and second embodiments, this embodiment provides a connection diagram of the first slide 7 and the second slide 8, which is as follows:

[0041] A plurality of first slide posts 12 are fixed on the first slideway 7, a plurality of first slide holes adapted to the first slide posts 12 are provided on the second slideway 8, and the second slideway 8 is slidably installed on the first slideway 7 through the cooperation between the first slide holes and the first slide posts 12, and the second slideway 8 can utilize the close cooperation between these slide holes and the first slide posts 12 to realize stable and accurate up and down sliding installation on the first slideway 7. This sliding installation method ensures the stability of the second slideway 8 during movement.

[0042] The bottom frame 2 is fixed to the conveying device 1 through a connecting rod 201. A plurality of second slide posts 13 are fixed to the four corners of the bottom frame 2. A second slide hole adapted to the second slide post 13 is provided on the top frame 3. The top frame 3 and the bottom frame 2 are connected by sliding up and down through the cooperation between the second slide post 13 and the second slide hole. The bottom frame 2 is a stable foundation for the entire device. It is tightly fixed to the conveying device 1 through a series of connecting rods 201, ensuring the stability of the entire system during operation. In order to further enhance the flexibility of the system, a plurality of second slide posts 13 are specially designed at the four corners of the bottom frame 2. These slide posts not only play a supporting role, but also serve as a guide component for the sliding of the top frame 3. Correspondingly, a second slide hole fully adapted to the shape and size of the second slide post 13 is provided on the top frame 3. Through the close cooperation between these slide holes and the second slide post 13, the top frame 3 is designed to be able to slide up and down along the bottom frame 2.

[0043] A bearing 16 is fixed to the position of the inner pin 5 located at the fixed block 10 . The bearing 16 is rotatably installed inside the fixed block 10 . The bearing 16 can support the inner pin 5 and prevent the shaft pin from falling downward under force.

[0044] Working principle:

[0045] The roller on the conveying device 1 is driven to rotate by a motor, pushing the metal product to move smoothly along the conveying channel, providing a stable conveying platform for the marking operation. The support frame is a double-layer structure, the bottom frame 2 is fixed to the conveying device 1 through a connecting rod 201, and the top frame 3 is slidably connected to the bottom frame 2 through a sliding column. The sliding connection design between the top frame 3 and the bottom frame 2 enables the nozzle to flexibly adjust the height in the vertical direction. The nozzle includes a shell 4 and an inner pin 5, the shell 4 is fixed on a slider 6, and the inner pin 5 is connected to the top frame 3. When the top frame 3 and the bottom frame 2 are in different states, the relative position of the inner pin 5 and the shell 4 will change, thereby controlling the spraying of the powder. At the same time, a driving gear 11 is provided at the upper end of the inner pin 5, which can drive the inner pin 5 to rotate through a linkage mechanism to push the powder in the storage chamber 401 to the discharge port. The design of the sphere 14 is used to block the discharge port when necessary to prevent powder leakage. The sliding movement of the slider 6 can be achieved by a cylinder or a screw drive.

[0046] In the oil cylinder drive mode, the piston movement of the oil cylinder drives the slider 6 and the first slide 7 to move; in the screw drive mode, the rotation of the screw interacts with the slider 6 and the thread groove inside the first slide 7 through the thread to achieve displacement control of the slider 6. The second slide 8 slides vertically on the first slide 7 through the slide rod, driving the movement of the nozzle in the vertical direction. The powder is transported to the storage chamber 401 of the nozzle through the pipeline through the external feeding device, and the powder in the storage chamber 401 accumulates at the bottom of the chamber under the action of gravity. When the inner pin 5 is separated from the discharge port, the powder will fall downward to the spiral body 15, and will be pushed to the discharge port for injection through the rotation of the spiral body 15.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate rather than limit the technical solutions of the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the present invention can still be modified or replaced by equivalents. Any modification or partial replacement that does not depart from the spirit and scope of the present invention should be included in the scope of the claims of the present invention.
