Description

Technical Field

[0001] The present invention relates to the technical field of anti-corrosion layer spraying devices for building materials, and in particular to a quick-detachable nozzle structure, a spraying device and a use method thereof. Background Art

[0002] For corrosion protection of building materials, a double-layer electroplating combined with a spray-coated anti-corrosion coating is widely recognized as a highly effective solution due to its synergistic protective effect. This process first forms a dense metal layer on the substrate surface through electroplating, providing cathodic protection and a physical barrier. A polymer anti-corrosion coating is then sprayed on to fill microscopic pores and resist environmental erosion, significantly extending the material's corrosion life in harsh environments such as salt spray and acid rain.

[0003] However, as a core functional component of a spraying system, nozzle replacement efficiency and connection reliability directly determine equipment operational continuity and maintenance costs. Conventional threaded connections remain the predominant method for nozzle attachment, resulting in low operational efficiency. Replacement requires manual thread alignment and tightening, a process that takes over 60 seconds per step. Repeated assembly and disassembly also leads to mechanical wear of the threaded pair, and the gradual increase in clearance between the threads not only contaminates the equipment but also wastes materials. Summary of the Invention

[0004] In order to solve the above problems, the present invention proposes a construction material anti-corrosion layer spraying device and a method of use to solve the above problems.

[0005] A quick-release nozzle structure includes a fan-shaped nozzle and a matching mounting member. The fan-shaped nozzle has an integral mounting portion on its exterior, which is equipped with a magnet. This mounting portion also has a slot, which contains a magnet. A block that fits within the slot is connected to the mounting member. The magnet provides initial suction force, simplifying the alignment process. This eliminates the need for manual precision adjustment, reducing replacement time and improving operational continuity.

[0006] Furthermore, the slots cooperate with the blocks on the mounting fixture to form a mechanical lock. Magnets help maintain a stable connection, preventing vibrations during the spraying process from causing the nozzle to loosen, ensuring reliability.

[0007] Furthermore, the one-piece design avoids additional connectors, and the slot structure has no threaded pairs. Long-term use will not cause the gap to increase due to wear, thereby reducing maintenance frequency and spare parts costs.

[0008] Furthermore, the card block includes a first plate-shaped portion and a second plate-shaped portion arranged perpendicular to the first plate-shaped portion. The second plate-shaped portion is provided with a magnet and cooperates with the magnet inside the card slot.

[0009] Furthermore, the L-shaped design of the card block, with the first plate-shaped portion for insertion and the second plate-shaped portion for rotational engagement, allows for quick "insert-rotate" installation that can be completed by the user without tools, greatly improving operational efficiency.

[0010] Furthermore, the double cooperation between the clamping block and the magnet in the clamping slot provides additional holding force, ensuring that it will not fall off under high-pressure spraying. At the same time, the mechanical clamping distributes the force, reducing the fatigue risk of the magnet alone.

[0011] Furthermore, a protrusion is provided on the upper surface of the fan-shaped nozzle, a sealing gasket is installed on the surface of the protrusion, and a pipe opening for connecting with the paint pipe is provided on the top of the mounting piece.

[0012] Furthermore, the staggered structure formed by the protrusions and the fixing grooves, combined with the elastic material of the sealing gasket, effectively prevents paint leakage, thus reducing material waste, keeping the equipment clean and avoiding pollution.

[0013] Furthermore, the protrusion and the fixing groove are automatically aligned under the guidance of magnetic attraction, which shortens the installation time and improves the sealing reliability.

[0014] Furthermore, a fixing groove matching the protrusion is provided at the bottom of the mounting piece, and a magnet is installed at the bottom of the mounting piece.

[0015] Furthermore, the standardized nozzle design simplifies paint pipe connections, supports quick switching between different paint types, and improves production flexibility. The base magnet works in conjunction with the nozzle magnet to ensure a tight fit between the mounting bracket and the nozzle, reducing installation errors.

[0016] A spraying device is equipped with a quick-release nozzle structure, including an operating table and a placement table arranged above the operating table. A mounting structure and a nozzle structure are arranged above the operating table. The mounting structure includes a support beam fixedly installed on the upper side of the operating table, an electric push rod is fixedly installed on the top of the support beam, and the output end of the electric push rod is fixedly connected to a mounting frame. A drive component for driving the nozzle structure to move horizontally is provided on one side of the mounting frame.

[0017] Furthermore, the electric push rod can drive the mounting frame, the driving assembly and the nozzle structure to move up and down, and the driving assembly can drive the nozzle structure to move horizontally, thereby adjusting the height and horizontal position of the nozzle structure.

[0018] Furthermore, the drive assembly includes a mounting shell fixedly mounted on one side of the mounting frame, a threaded rod is rotatably mounted inside the mounting shell, a moving block is threadedly connected to the outer side of the threaded rod, and a connecting block is fixedly connected between the moving block and the mounting member.

[0019] Furthermore, a first servo motor is fixedly mounted on one side of the mounting housing, and one end of the threaded rod is fixedly connected to an output end of the first servo motor. The threaded rod can be driven to rotate by the first servo motor to control the rotation direction of the threaded rod.

[0020] Furthermore, a through slot is defined on one side of the mounting housing, adapted to accommodate the connecting block. The connecting block extends through the slot and is slidably connected to the slot. The connecting block slides along the slot on one side of the mounting housing, limiting the position of the connecting block and the movable block. A sliding block on one side of the mounting frame slides along a slide member on one side of the support beam, limiting the travel of the mounting frame and ensuring stable raising and lowering of the mounting frame.

[0021] Furthermore, a mounting shaft is fixedly installed on the top of the placement table, and the mounting shaft is rotatably connected to the operating table through a bearing seat. A rotating structure is provided at the bottom of the operating table, and the rotating structure includes a protective shell fixedly installed on the bottom of the operating table, and a second servo motor is fixedly installed on one side of the protective shell. The output end of the second servo motor is fixedly connected to the first bevel gear, and the bottom end of the mounting shaft is fixedly connected to the second bevel gear meshing with the first bevel gear.

[0022] A method for using a spraying device comprises the following steps:

[0023] (a1) Fixing the workpiece: Place the building material to be sprayed on the placement table and fix it;

[0024] (a2) Paint supply: Connect the paint pipe to the nozzle on the top of the mounting part to supply the anti-corrosion paint to the fan-shaped nozzle;

[0025] (a3) Adjust the nozzle height: Start the electric push rod to drive the mounting frame, drive assembly and nozzle structure to the preset height;

[0026] (a4) Horizontal movement of the nozzle: start the first servo motor to drive the threaded rod to rotate;

[0027] The threaded rod drives the moving block to move horizontally, and pushes the nozzle structure to move back and forth through the connecting block;

[0028] (a5) Adjusting the workpiece rotation: starting the second servo motor to drive the first bevel gear to rotate; the first bevel gear engages with the second bevel gear to drive the mounting shaft to rotate, so that the placement table drives the workpiece to rotate;

[0029] (a6) Start synchronous spraying: Combine the horizontal reciprocating movement of the nozzle, height adjustment and continuous rotation of the workpiece to achieve all-round uniform spraying of the building material.

[0030] During use, the building materials to be processed are placed on the placement table and fixed, and the external paint pipe at the pipe mouth on the top of the mounting part transports paint to the mounting part and the fan-shaped nozzle. At the same time, the electric push rod is started to drive the mounting frame, drive assembly and nozzle structure to a suitable height, and the first servo motor is started to control the rotation of the threaded rod, driving the moving block, connecting block and nozzle structure threadedly connected to it to move, controlling the reciprocating horizontal movement of the nozzle structure, and the second servo motor is started to drive the first bevel gear, the second bevel gear, the mounting shaft and the placement table to rotate, thereby realizing the rotation adjustment of the building materials to be processed and completing the all-round spraying treatment of the building materials.

[0031] By adopting the above technical solution, the second servo motor can drive the first bevel gear, the second bevel gear and the installation shaft to rotate, and the installation shaft can then drive the placement table to rotate, thereby realizing the rotation adjustment of the building materials to be processed, and facilitating the completion of all-round spraying.

[0032] Compared with the existing technology, the present application has the following beneficial effects: through the coordinated arrangement of the various components in the nozzle structure, a quick-release connection structure combining snaps and magnetic attraction is adopted to achieve rapid disassembly and assembly between the fan-shaped nozzle and the mounting part, shortening the nozzle replacement time while providing stable connection and fixation, thereby improving replacement efficiency.

[0033] The mounting frame, drive assembly and nozzle structure are lifted and lowered by an electric push rod. The drive assembly can drive the nozzle structure to move horizontally to adjust the height and horizontal position of the nozzle structure. In conjunction with the setting of the rotating structure, it can drive the rotation and adjustment of the placement table and the building materials to be processed to complete a full range of spraying processing.
