Description

Technical Field

[0001] The utility model relates to the technical field of laser water washing equipment, in particular to a light blocking structure of a laser water washing device. Background Art

[0002] Laser washing (laser cleaning) is a surface cleaning process that uses laser technology. It uses a focused laser to act on the surface of denim fabric, causing it to vaporize or peel off the surface part quickly, thereby achieving the effect of wear or fading. It is non-contact, consumable, pollution-free, highly precise, and damage-free or minimal.

[0003] Lasers are dangerous due to their high energy. During loading and unloading of laser washers, workers often extend their bodies under the scanning head, posing a significant safety hazard. Existing technology involves installing a switch inside the optical path component to block the emission of light. However, optical path components are high-precision electronic devices and are susceptible to electromagnetic interference, which can lead to unexpected opening of the switch or scattering of light. Summary of the Invention

[0004] In response to the problems in the related technology, the utility model proposes a light-blocking structure for a laser water washing device, which can be opened before the laser works and closed after the laser works to block the laser that may be emitted, avoid safety hazards, and can be used / operated stably.

[0005] The utility model is achieved in this way:

[0006] A light-blocking structure for a laser water cleaning device, wherein a working area is provided inside the laser water cleaning device; a light outlet is provided at the top of the working area, and a laser generating unit is fixedly provided above the light outlet; an operating table is provided at the bottom of the working area; an operating port is provided on the side of the laser water cleaning device, the operating port being in communication with the working area; laser light generated by the laser generating unit is emitted from the light outlet toward the operating table;

[0007] The light blocking structure includes a rotatable light blocking plate and a driving unit; the driving unit is in transmission connection with the light blocking plate; the rotation axis of the light blocking plate faces the horizontal direction;

[0008] When the laser generating unit does not emit light, the light blocking plate is horizontally oriented and blocks the light outlet, thus being in a closed state;

[0009] When the laser generating unit emits light normally, the light shielding plate rotates toward the operating port by a preset angle and is in an open state; the preset angle is at least 90°.

[0010] The light-blocking structure is separated from the laser generating unit to avoid electromagnetic interference and ensure stable operation. The light-blocking plate can be automatically closed or opened at different stages to prevent the laser from directly hitting the workers.

[0011] As a further optimization of the above solution, it further includes a positioning unit; the positioning unit rotates synchronously with the light barrier;

[0012] A first positioner and a second positioner are also fixedly provided in the working area;

[0013] When the positioning unit cooperates with the first positioner, the light shield is in a closed state;

[0014] When the positioning unit cooperates with the second positioner, the light shield is in an open state.

[0015] The rotation angle of the light barrier can be identified and controlled according to the position of the positioning unit, that is, the start and stop of the light barrier can be controlled. Specifically, the first positioner, the second positioner, the drive unit and the control unit can be connected to each other by telecommunications to start and stop the drive unit according to the signal.

[0016] As a further optimization of the above solution, the driving unit is a motor; the motor is fixedly arranged on the top of the working area; the output end of the motor is horizontally oriented;

[0017] The light blocking plate is a rectangular structure, and the two short sides and one long side of the light blocking plate are vertically bent toward the same side to form a bent portion;

[0018] It also includes a connecting piece; the connecting piece is a block structure; the output end of the motor is fixedly connected to the connecting piece; the connecting piece is also fixedly connected to the bent portion of the light shielding plate on a short side.

[0019] The light-blocking plate has a relatively simple structure and has no rotating shaft. The cooperation between the connecting piece and the bending part can enhance the connection stability between the motor output end and the light-blocking plate, ensuring stable transmission. At the same time, the setting of the bending part also improves the structural strength of the light-blocking plate.

[0020] As a further optimization of the above solution, the extension line of the output end of the motor coincides with a long side of the light-blocking plate having a bent portion;

[0021] It also includes a light shielding plate; the light shielding plate is vertically fixed on the top of the working area, and the two sides of the light shielding plate face the horizontal direction; the light shielding plate is located below the light shielding plate; one long side of the light shielding plate is adjacent to the lower edge of the light shielding plate and is parallel to each other.

[0022] As a further optimization of the above solution, the upper edge of the light shielding plate is adjacent to the edge of the light outlet.

[0023] As a further optimization of the above solution, the first locator and the second locator are both U-shaped photoelectric switches; the U-shaped photoelectric switches have a U-shaped groove;

[0024] The positioning unit is an L-shaped sheet structure, comprising a fixing surface and a positioning surface perpendicular to each other; the fixing surface is fixedly connected to the connecting member; the orientation of the positioning surface is the same as the orientation of the output end of the motor; when the light baffle rotates, the positioning surface rotates synchronously;

[0025] The positioning surface is embedded in the U-shaped groove, which means that the positioning unit cooperates with the first positioner or the second positioner.

[0026] As a further optimization of the above solution, it also includes a motor fixing seat; the motor fixing seat includes a horizontal plate portion and a vertical plate portion; the horizontal plate portion is arranged at the top of the working area and is fixedly connected to the laser water washing device; the vertical plate portion is perpendicular to the surface of the horizontal plate portion, so that the motor fixing seat has a T-shaped structure; the motor is fixedly connected to the vertical plate portion, and the output end of the motor passes through the vertical plate portion.

[0027] As a further optimization of the above solution, the edge of the operating table close to the operating port is a limit edge;

[0028] When the light barrier is in an open state, the maximum angle light emitted by the laser generating unit is emitted along the surface of the light barrier and finally hits the limit edge or does not exceed the limit edge.

[0029] As a further optimization of the above solution, the number of the light blocking plates is one or two.

[0030] As a further optimization of the above solution, the number of the operation ports is one or two;

[0031] When there are two operating ports and two light shielding plates, the two operating ports are on opposite sides of each other. In the open state, the two light shielding plates respectively rotate toward the closest operating port.

[0032] The utility model provides a light blocking structure for a laser water washing device, which has the following beneficial effects:

[0033] (1) The light shield can rotate automatically and open automatically when the laser generating unit is working; when the laser stops emitting or the user adjusts or replaces the fabric, the light shield will automatically block the laser generating unit to prevent the laser from directly shining on the user and causing safety hazards;

[0034] (2) The light shield drive unit is separated from the laser generating unit, which prevents electromagnetic interference and avoids hidden dangers such as the light shield failing to open or close normally or abnormal laser emission;

[0035] (3) Setting a positioning unit and a positioner to adjust the rotation degree of the auxiliary driving unit to ensure the stable rotation of the light barrier;

[0036] (4) The light shield is set at a preset angle, and the laser can only be emitted along the light shield to the edge of the operating table at most, avoiding accidental emission outside the working area. BRIEF DESCRIPTION OF THE DRAWINGS
