Description

Technical Field

[0001] The utility model relates to the technical field of the chemical fiber industry, and particularly relates to a device for cleaning micropores of a spinneret by using laser. Background Art

[0002] A spinneret is an indispensable precision part in a spinning machine in the chemical fiber industry. In the high-speed spinning production process of polyester filaments, mechanical impurities, gels, carbonization, heat and other microparticles existing in the melt often block the micropores of the spinneret, resulting in uneven fineness of the spun filaments and defects such as "stub yarn", "thin yarn", "fuzz yarn", etc. Therefore, the spinneret and its micropores need to be cleaned regularly.

[0003] At present, the cleaning of spinnerets generally uses chemical reagents for cleaning, and the process is as follows: calcination (or salt bath, triethylene glycol, etc.) - or alkali boiling (or triethylene glycol boiling) - ultrasonic cleaning - microscopy. Using chemical reagents for cleaning is relatively inconvenient in operation and consumes a large amount of chemical reagents. It is not only easy to corrode the micropores of the spinneret, but also generates a large amount of pollutants, causing environmental pollution. In the prior art, there are also some ways to clean spinnerets by using laser, but usually the spinneret is clamped and suspended in the air for cleaning both the front and back sides. This method ensures work efficiency, but there are spinnerets of different thicknesses and sizes. The position of the suspended spinneret is fixed relative to the laser module, which may affect the distance between the laser module and the spinneret, making the focal length required by the laser module not meet the requirements of laser cleaning, and thus affecting the laser cleaning effect. Summary of the Invention

[0004] The purpose of the utility model is to overcome the defects of the prior art and provide a device for cleaning micropores of a spinneret by using laser, which adopts the laser cleaning method and can adjust the laser focal length.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A device for cleaning micropores of a spinneret by using laser, comprising a laser cleaning mechanism and a laser cleaning working platform; a spinneret placement area for placing the spinneret is provided on the laser cleaning working platform, and the laser cleaning mechanism includes:

[0007] A laser module for emitting laser to clean the spinneret;

[0008] A distance adjustment module for adjusting the distance between the laser module and the spinneret on the spinneret placement area to adjust the focal length required for laser cleaning by the laser module.

[0009] In the present utility model, a spinneret is cleaned by means of laser cleaning. When performing laser cleaning, the spinneret is placed in the spinneret placement area, and the distance between the laser module and the spinneret placement area is adjusted by a distance adjustment module. Thus, the focal length required for laser cleaning can be adjusted according to the thickness of the spinneret, ensuring that the distance between the laser emission surface and the cleaning surface meets the requirements.

[0010] In the present utility model, the distance adjustment module can adopt various existing drive structure forms.

[0011] Preferably, the spinneret placement area is provided with through holes arranged in an array.

[0012] During laser cleaning operation, soot and ash will be generated on the surface of the spinneret, which are likely to adhere to the surface of the spinneret and block the micropores of the spinneret. The soot will also pose a hazard to the health of the operator inside the equipment. Preferably, a side blowing device for blowing air towards the spinneret is provided on the side of the laser cleaning working platform.

[0013] In the present utility model, the side blowing device can include a nozzle and a valve block. The side blowing device can be provided in two and arranged diagonally. High-pressure air passes through the nozzle and the valve block to blow high-pressure air onto the surface and micropores of the spinneret to remove impurities such as soot and ash on the surface and inside the spinneret.

[0014] Preferably, a dust suction device is provided on the laser cleaning working platform.

[0015] Preferably, the dust suction device includes a bottom dust suction device provided at the bottom of the laser cleaning working platform and a side dust suction device provided on the side of the laser cleaning working platform.

[0016] In the present utility model, the ash or blockage in the micropores of the spinneret can be absorbed by the bottom dust suction device through the through holes, and the soot, floating ash, and burned substances on the surface of the spinneret can be blown into the side dust suction device by the side blowing device. The bottom dust suction device and the side dust suction device can ensure that the equipment and the indoor environment are clean and tidy during the spinneret cleaning operation.

[0017] Preferably, a dust-proof cover is provided on the laser cleaning working platform. In the present utility model, the dust-proof cover can prevent impurities such as soot and floating ash from spreading into the equipment and the external environment.

[0018] Preferably, it further includes:

[0019] A clamping and flipping mechanism for clamping the spinneret and capable of flipping the spinneret;

[0020] A moving platform for driving the clamping and flipping mechanism to move so as to transport the spinneret clamped by the clamping and flipping mechanism to the spinneret placement area.

[0021] In the present utility model, the clamping and flipping mechanism is installed on the mobile platform. The mobile platform can be a two-axis mobile platform, and the two-axis mobile platform uses 2 motor modules to achieve horizontal movement and vertical lifting. The clamping and flipping mechanism consists of a pneumatic gripper and a hollow rotary motor, which realizes the clamping and flipping of the spinneret workpiece.

[0022] The two-axis mobile platform drives the clamping and flipping mechanism to clamp the spinneret workpiece, realizing the movement and handling of the spinneret from the conveying channel to the laser cleaning working platform.

[0023] Preferably, the laser cleaning working platform is further provided with a movable blowing device, and the movable blowing device can move relative to the clamping and flipping mechanism so that the blowing air flow direction corresponds to the micropores of the spinneret.

[0024] Preferably, it further includes:

[0025] A conveyor for conveying the spinneret to the cleaning station and conveying the spinneret after laser cleaning to the next process.

[0026] Preferably, it further includes a stop mechanism for blocking the spinneret on the conveyor to keep it at the cleaning station.

[0027] In the present utility model, the conveyor can adopt a double-row synchronous belt conveyor. When the spinneret workpiece enters the conveyor belt and the sensor senses that the spinneret reaches the position, the stop mechanism is activated to prevent the spinneret workpiece from stopping moving and the conveyor stops working. The stop mechanism of the present utility model can include a stop rod and a driving structure for driving the stop rod to extend and retract. For example, when the stop rod extends, it blocks the spinneret, and when it retracts, the spinneret can continue to be conveyed.

[0028] When the present utility model performs laser cleaning, the specific operations include:

[0029] The clamping and flipping mechanism drives the clamping of the spinneret workpiece under the drive of the mobile platform (which can adopt the two-axis mobile platform mode), transfers the spinneret workpiece to the spinneret placement area of the laser cleaning workbench, and the laser module performs laser cleaning on the spinneret workpiece. The air nozzles of the side blowing device on the laser cleaning workbench blow air on the spinneret for dust removal, and the bottom dust suction device and the side dust suction device adsorb the generated ashes, soot and the attached substances burned by the laser.

[0030] After the above-mentioned one-time laser cleaning, the clamping and flipping mechanism clamps the spinneret workpiece, lifts it to a certain height, flips the spinneret workpiece by 90 degrees, the movable blowing device on the laser cleaning workbench blows air vertically on the spinneret and its micropores, and the dust suction device on the laser cleaning fixed platform adsorbs the generated ashes and the attached substances burned by the laser.

[0031] The clamping and flipping mechanism flips the spinneret plate back to 180 degrees again. The moving platform places the spinneret plate back on the laser cleaning workbench. The laser module conducts laser cleaning on the spinneret plate workpiece again. The side air blowing device on the laser cleaning workbench blows air on the spinneret plate to remove dust. The side dust suction device and the bottom dust suction device adsorb the generated ashes, soot, and the attached substances burned by the laser.

[0032] The clamping and flipping mechanism flips the spinneret plate to 270 degrees again. The movable air blowing device on the laser cleaning workbench blows air vertically on the spinneret plate and its micropores. The dust suction device on the laser cleaning workbench adsorbs the generated ashes and the attached substances burned by the laser.

[0033] The clamping and flipping mechanism resets the spinneret plate to the 0-degree plane. The moving platform drives the clamping and flipping mechanism to place the spinneret plate workpiece back on the conveyor. The conveyor operates to transport the spinneret plate to the next process.

[0034] The beneficial effects of the present utility model compared with the prior art are:

[0035] In the present utility model, the spinneret plate is placed on a fixed working surface for cleaning, ensuring that the working focal length during laser cleaning is within the set range, and avoiding the reduction of laser cleaning performance caused by the influence of the laser focal length when cleaning the floating spinneret plate.

[0077] Driven by a moving platform (a two-axis moving platform can be used), the clamping and flipping mechanism clamps the spinneret workpiece and transfers the spinneret workpiece to the spinneret placement area of the laser cleaning workbench.
