Description

Technical Field

[0001] This utility model relates to the field of nozzle technology, and in particular to a self-limiting calibration curved surface forming nozzle. Background Technology

[0002] Existing nozzles with calibration functions use calibration components to obtain the reference position parameters of the nozzle detection reference point to ensure the accuracy of nozzle spraying. The nozzle position is then precisely calibrated using these parameters. However, this method is not convenient for adjusting the nozzle tilt angle, requiring manual adjustment by the operator, which is inconvenient. For example, a nozzle position precision calibration device disclosed in Chinese Patent Application No. CN202220656834.8 uses a calibration device to obtain the reference position parameters of the detection reference point on the reference nozzle. The position of the nozzle at the calibration location is then precisely calibrated using these reference parameters. However, this method is also not convenient for adjusting the nozzle tilt angle, requiring manual adjustment by the operator, which is inconvenient. Utility Model Content

[0003] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a self-limiting and calibrating curved surface forming nozzle. The nozzle tip adopts a curved surface forming design, and a calibration surface is formed on the upper surface of the limiting block. The calibration surface is inclined. After the device is disassembled and assembled, the inner wall of the nozzle tube can fit with the calibration surface, realizing the automatic limiting calibration of the nozzle tube. This ensures that the nozzle tube always maintains the optimal distance from the curved surface, and the nozzle tilt angle can be adjusted to ensure that the material spraying direction is perpendicular to the curved surface of the nozzle tip, reducing anisotropy. The gasket can squeeze the gasket and the retaining spring on its lower surface, so that the retaining spring squeezes the locking block, realizing the locking block fastening the limiting block and the internal nozzle. It can also reduce the vibration generated when spraying materials and ensure the stability of the spraying shape.

[0004] This utility model also provides a curved surface forming nozzle with the above-mentioned self-limiting calibration, comprising: a nozzle tube, a gasket at the bottom end of the nozzle tube, a torsion spring fixedly connected to the side surface of the nozzle tube, a handle fixedly connected to the top end of the torsion spring, a pull rod on the lower surface of the handle, a locking block at the bottom end of the nozzle tube, a gasket on the side surface of the locking block, and a retaining spring on the lower surface of the gasket; and a mounting block, a limiting block inside the mounting block, a curved surface formed at the contact point between the limiting block and the mounting block, a guide block on the upper surface of the limiting block, a calibration surface on the upper surface of the limiting block, and a nozzle inside the limiting block. The above components incorporate a curved surface design for the nozzle tip. A calibration surface is provided on the upper surface of the limiting block, and this surface is inclined. After disassembly and assembly, the inner wall of the nozzle tube can fit against the calibration surface, achieving automatic limiting calibration of the nozzle tube. This ensures that the nozzle tube maintains the optimal distance from the curved surface and allows adjustment of the nozzle tilt angle. This ensures that the material spraying direction is perpendicular to the curved surface of the nozzle tip, reducing anisotropy. The gasket can compress the gasket and the retaining spring on its lower surface, causing the retaining spring to compress the locking block. This secures the locking block to the limiting block and the internal nozzle, reducing vibration during material spraying and ensuring the stability of the spray shape.

[0005] According to the present invention, a self-limiting and calibrated curved surface forming nozzle includes a nozzle shell on the side surface of the nozzle tube. The bottom end of the nozzle shell is fixedly connected to the inner wall of the pad shell, and the top of the handle and pull rod are located at the top of the nozzle shell. These components protect the torsion spring and the nozzle tube from the nozzle shell, while ensuring that the top of the handle and pull rod is outside the nozzle shell.

[0006] According to the present invention, a self-limiting and calibrated curved surface forming nozzle includes a limiting ring fixedly connected to the side surface of the nozzle housing, and the upper surface of the nozzle housing contacting the top end of the nozzle tube. Through these components, the limiting ring limits the pull rod, facilitating control of the nozzle tube's rotation.

[0007] According to the present invention, a self-limiting and calibrated curved surface forming nozzle has an inner wall of a limiting ring in contact with a pull rod, and the bottom end of the pull rod is engaged with the bottom end of the nozzle tube. These components enable the pull rod to rotate the nozzle tube, facilitating nozzle tube installation.

[0008] According to the self-limiting calibration curved surface forming nozzle of this utility model, the upper surface of the gasket is in contact with the lower surface of the gasket shell, and the inner wall of the retaining spring is fitted with the side surface of the locking block. These components facilitate the compression of the gasket by the gasket shell, allowing the gasket and retaining spring to secure the locking block.

[0009] According to the present invention, a self-limiting and calibrated curved surface forming nozzle comprises a guide block side surface that fits against the inner wall of the nozzle tube, and a calibration surface that fits into the inner wall of the nozzle tube. These components enable the guide block to discharge material, preventing leakage, and the calibration surface, in conjunction with the nozzle tube, achieves self-limiting and calibrating of the nozzle tube.

[0010] According to the present invention, a self-limiting and calibrated curved surface forming nozzle comprises a limiting block side surface that fits against the inner wall of a locking block, and a mounting block located on the side of the locking block and the nozzle housing. These components enable the locking block to secure the limiting block and the mounting block to protect the internal components.

[0011] According to the present invention, a self-limiting and calibrated curved surface forming nozzle has a nozzle tip located inside the nozzle tube and a nozzle middle located inside the material guide block. These components allow material to flow laterally from the nozzle.

[0012] Beneficial effects:

[0013] Compared with the prior art, this utility model adopts a curved surface design for the nozzle tip and a calibration surface is provided on the upper surface of the limiting block. The calibration surface is inclined. After the device is disassembled and assembled, the inner wall of the nozzle tube can fit with the calibration surface, realizing automatic limiting calibration of the nozzle tube. This ensures that the nozzle tube always maintains the optimal distance from the curved surface and can adjust the nozzle tilt angle to ensure that the material spraying direction is perpendicular to the curved surface of the nozzle tip, reducing anisotropy. The pad can squeeze the pad and the retaining spring on its lower surface, so that the retaining spring squeezes the locking block, realizing the locking block fastening the limiting block and the internal nozzle. It can also reduce the vibration generated when spraying materials and ensure the stability of the spray shape. Attached Figure Description

[0023] Specifically, the gasket 2 can compress the gasket 7 and the retaining spring 8 on its lower surface, causing the retaining spring 8 to compress the locking block 6. The locking block 6 can then fasten the limiting block 10 inside it. The operator can control the rotation of the nozzle tube 1 through the handle 4 and the pull rod 5 to adjust the rotation of the nozzle 14 inside it, so that the nozzle tube 1 and the nozzle 14 can match the curved surface 11, preventing the nozzle angle from having a negative impact on the spraying effect.

[0025] Specifically, the limiting block 10 can restrict the nozzle tube 1 and the nozzle head 14 inside, and the calibration surface 13 on the upper surface of the limiting block 10 can fit into the inner wall of the nozzle tube 1. After the device is disassembled and assembled, the inner wall of the nozzle tube 1 can fit into the calibration surface 13, realizing the automatic limiting calibration of the nozzle tube 1, so that the nozzle tube 1 always maintains the optimal distance from the curved surface 11, and the nozzle tilt angle can be adjusted to ensure that the material spraying direction is perpendicular to the curved surface 11 at the tip of the nozzle head 14, reducing anisotropy.

[0026] Working principle: During the use of the device, the pad 2 can compress the pad 7 and the retaining spring 8 on its lower surface, so that the retaining spring 8 compresses the locking block 6, and the locking block 6 can fasten the limiting block 10 inside. The operator can control the rotation of the nozzle tube 1 through the handle 4 and the pull rod 5 to adjust the rotation of the nozzle 14 inside, so that the nozzle tube 1 and the nozzle 14 can match the curved surface 11, preventing the nozzle angle from having a negative impact on the spraying effect. The limiting block 10 can restrict the nozzle tube 1 and the nozzle 14 inside, and the calibration surface 13 on the upper surface of the limiting block 10 can fit into the inner wall of the nozzle tube 1. After the device is disassembled and assembled, the inner wall of the nozzle tube 1 can fit into the calibration surface 13, realizing the automatic limiting calibration of the nozzle tube 1, so that the nozzle tube 1 always maintains the optimal distance from the curved surface 11, and can adjust the nozzle tilt angle to ensure that the material spraying direction is perpendicular to the curved surface 11 at the tip of the nozzle 14, reducing anisotropy.
