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 multiple spinnerets by laser cleaning. Background Art

[0002] The spinneret is an indispensable precision part in the spinning machine of the chemical fiber industry. In the production process of high-speed spinning of polyester filaments, mechanical impurities, gels, carbonization, heat generation 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 yarns", "fine yarns", "hairs", 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 inconvenient to operate and consumes a large amount of chemical reagents. It not only easily corrodes the micropores of the spinneret, but also generates a large amount of pollutants, causing environmental pollution. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the defects of the prior art and provide a device for cleaning micropores of multiple spinnerets by laser cleaning, which uses the laser cleaning method to clean the spinneret.

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

[0006] A device for cleaning micropores of multiple spinnerets by laser cleaning, characterized by comprising:

[0007] A laser device, which is arranged at the laser cleaning station and is used to emit laser to clean the spinneret;

[0008] A cleaning fixture, which has a plurality of spinneret positioning holes. When the spinneret is fixed in the spinneret positioning holes, the front and back sides of the spinneret are respectively exposed on both sides of the spinneret positioning holes;

[0009] A swing clamping mechanism, which is used to clamp the cleaning fixture at the cleaning station and can flip the cleaning fixture so that the front and back sides of the spinneret on the cleaning fixture can respectively face the laser device, and then laser cleaning of the front and back sides can be carried out respectively.

[0010] The present invention uses laser cleaning to clean spinnerets. First, several spinnerets are placed on a cleaning fixture. The fixture is then swiveled to clamp the fixture and flip it over. Since the front and back sides of the spinnerets are exposed to both sides of the spinneret positioning holes, flipping the fixture allows the front and back sides of the spinnerets on the fixture to correspond to the laser device, allowing laser cleaning of both sides. Furthermore, the cleaning fixture can hold multiple spinnerets simultaneously, allowing for multiple cleaning operations, significantly improving cleaning efficiency.

[0011] In order to improve the cleaning efficiency, it is preferred to further include:

[0012] The conveying mechanism is used to convey the cleaning fixture to the laser cleaning station.

[0013] As an advantage, it also includes:

[0014] The lifting mechanism is arranged at the laser cleaning station and is used for lifting the cleaning fixture so that the swing clamping mechanism can clamp the cleaning fixture.

[0015] When the cleaning fixture is located at the laser cleaning station, the sensor senses that there is a cleaning fixture here, and the lifting mechanism lifts the cleaning fixture here. After it is lifted into place, the swing clamping mechanism located above clamps the cleaning fixture, and the lifting mechanism returns to its original position. At this time, the swing clamping mechanism flips over to perform laser cleaning of the spinneret. After cleaning is completed, the lifting mechanism rises to take over the cleaning fixture, and finally descends to its original position and is transported out by the conveying mechanism. The above process is repeated to operate the next cleaning fixture.

[0016] The jacking mechanism in the present invention has various structural forms and can adopt various structural forms. As a preferred embodiment, the jacking mechanism includes:

[0017] a lifting plate, used for supporting the cleaning fixture transported by the transport mechanism;

[0018] The lifting cylinder is used to drive the lifting plate to rise and fall.

[0019] The cleaning fixture of the present invention can have various structural forms and can adopt various structural forms. As a preferred embodiment, the cleaning fixture includes:

[0020] A lower base plate having a plurality of lower clamping holes matched with the spinneret;

[0021] An upper base plate is detachably connected to the lower base plate and has a plurality of upper clamping holes corresponding one-to-one to the lower clamping holes of the lower base plate;

[0022] When the upper clamping hole and the lower clamping hole correspond to each other, the spinneret positioning hole is formed.

[0023] In the present utility model, the spinneret is fixed in the upper and lower clamping holes through the upper bottom plate and the lower bottom plate. First, place the spinneret in the lower clamping hole, and then cover the upper bottom plate on the lower bottom plate, so that the upper and lower clamping holes correspond one by one to fix the spinneret.

[0024] Preferably, the lower bottom plate and the upper bottom plate are in sliding fit with each other, and are locked by a locking mechanism between the lower bottom plate and the upper bottom plate.

[0025] In the present utility model, a sliding fit manner can be adopted between the upper bottom plate and the lower bottom plate. When it is necessary to place the spinneret, just pull the upper bottom plate. After placing it, lock it through the locking mechanism. There can also be various structural forms of the locking mechanism. For example, screws can be used.

[0026] There can also be various cooperation manners between the upper bottom plate and the lower bottom plate in the present utility model. For example, it can be set as a hinged manner. For example, one end of the upper bottom plate and the lower bottom plate is hinged. After loading the spinneret, the upper bottom plate is flipped and covered on the lower bottom plate, and then locked through the locking mechanism.

[0027] Preferably, the laser device includes a laser emitter and a laser moving three-axis platform for driving the laser emitter to move in three-dimensional directions.

[0028] In the present utility model, the laser moving three-axis platform can drive the laser emitter to move in three-dimensional directions. For example, it moves up and down along the Z-axis to control the distance between the laser emitter and the spinneret workpiece, so that this distance conforms to the working focal length of the laser. A ranging sensor is arranged on the laser device to feedback and measure the distance from the laser emitter to the working surface of the spinneret. The laser device moves in two directions of the XY axis, and can perform laser cleaning on each spinneret on the cleaning fixture.

[0029] Preferably, the laser device further includes a dust suction mechanism for absorbing the residues after laser cleaning. In order to remove the residues after cleaning, the residues can be absorbed through the dust suction mechanism. There are various structural forms of the dust suction mechanism. The dust suction hood can be set to be connected to a vacuum cleaner for dust suction.

[0030] One or more swing clamping mechanisms can be set in the present utility model. Preferably, there are two swing clamping mechanisms, which are arranged oppositely and are respectively used for clamping the opposite ends of the cleaning fixture. The two swing clamping mechanisms make the cleaning fixture clamped more firmly.

[0031] Preferably, the swing clamping mechanism includes a clamping jaw, a clamping cylinder and a swing cylinder.

[0032] Preferably, it further includes:

[0033] A blowing dust removal device for purging a cleaning fixture after laser cleaning.

[0034] In the present utility model, a blowing dust removal device can be arranged at the end of the conveying mechanism. The blowing dust removal device uses high-pressure air to blow and remove dust from the cleaning fixture. By adopting auxiliary devices such as dust suction and blowing, the cleaning cleanliness of the spinneret workpiece is improved.

[0035] The beneficial effects of the present utility model compared with the prior art are as follows:

[0036] In the present utility model, the spinneret is cleaned by laser cleaning. First, several spinnerets can be placed on the cleaning fixture, and then the swing clamping mechanism clamps the cleaning fixture and can flip the cleaning fixture. Since the front and back sides of the spinneret are exposed on both sides of the spinneret positioning hole, when the cleaning fixture is flipped, the front and back sides of the spinneret on the cleaning fixture can respectively correspond to the laser device, so as to perform laser cleaning on the front and back sides of the spinneret. And in the present utility model, multiple spinnerets can be placed on the cleaning fixture at the same time, so multiple spinnerets can be cleaned, greatly improving the cleaning efficiency. In addition, the laser device is controlled by a three-axis moving platform to move, and automatically and continuously performs laser cleaning on multiple spinneret workpieces, improving the working efficiency of cleaning the spinneret workpieces.
