Description

Technical Field

[0001] The utility model relates to the technical field of polishing and filtering, in particular to an optical lens polishing and filtering machine. Background Art

[0002] A lens is an optical element made of transparent material with a spherical surface. There are two types of lenses: plastic lenses and glass lenses. The processing technology of lenses is divided into hot processing and cold processing. Since glass is easy to adhere to the mold surface during hot processing, and the product is also prone to pores and cold mold marks, lenses are mostly cold processed. The head lens needs to be polished during the cold processing stage. Before polishing, the lens needs to be coarsely ground, then finely ground, and finally polished. During this period, polishing fluid is required. The polishing fluid takes away the worn particles during the coarse and fine grinding process. Since the polishing fluid is expensive, it generally needs to be reused. Therefore, the used polishing fluid needs to be filtered, and the filter residue after filtering the polishing fluid accumulates on the surface of the filter. The accumulation of filter residue on the surface of the filter reduces the filtering effect and needs to be manually cleaned, thereby reducing the cleaning efficiency.

[0003] For example, a polishing and filtering device for cold processing of optical lenses disclosed in a Chinese patent document (publication number: CN214389046U) uses a tube slip ring to drive the mounting frame and the slide rod to slide inside the mounting plate, and uses the slide rod to pull the spring, and the elastic force of the spring drives the slide rod to vibrate, thereby vibrating the filter screen and causing the filter residue to fall from the surface of the filter screen. The filter residue falls to the bottom end of the U-shaped through pipe under the action of gravity, and the regulating valve is opened to discharge the filter residue from the inside of the through pipe along the sewage pipe. However, since the filter screen is located inside the pipeline, it is impossible to know whether the filter screen is blocked, so it needs to be cleaned by manual vibration at regular intervals, and the cleaning effect by vibration is poor, which not only makes the operation more cumbersome, but also increases manual labor and wastes manual labor.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-Figure 4 The utility model provides a technical solution: an optical lens polishing filter, comprising a mounting plate 1, the inner wall of the mounting plate 1 is respectively fixedly sleeved with a first filter tube 2 and a second filter tube 3, the lower end of the first filter tube 2 is fixedly connected with an arc-shaped elbow 4, one end of the arc-shaped elbow 4 is fixedly connected with the lower end of the second filter tube 3, the outer surface of the arc-shaped elbow 4 is fixedly connected with a drain pipe 5, and the outer surface of the drain pipe 5 is fixedly installed with a solenoid valve 6;

[0021] An automatic cleaning device is provided at the upper end of the first filter tube 2 , and the automatic cleaning device includes a filter bucket 7 , and the lower surface of the filter bucket 7 is fixedly connected to the upper end of the first filter tube 2 .

[0022] Furthermore, a fixed frame 71 is movably inserted into the front of the filter bucket 7, and the two side surfaces of the fixed frame 71 are respectively in contact with the two side inner walls of the filter bucket 7, and the back of the fixed frame 71 is in contact with the rear inner wall of the filter bucket 7. The arc-shaped bend pipe 4 has the characteristic of an arc-shaped inner wall, so that the impurities inside the first filter tube 2 and the second filter tube 3 will enter the sewage pipe 5 through the arc-shaped bend pipe 4 for storage after precipitation, and then the accumulated impurities are cleaned up by opening the solenoid valve 6 regularly.

[0023] Furthermore, a large-aperture filter screen 72 is fixedly sleeved on the inner wall of the fixed frame 71, a liquid level sensor 73 is fixedly installed on the inner wall of the first filter tube 2, a water outlet pipe 74 is fixedly connected to the outer surface of the second filter tube 3, and an annular mounting block 75 is fixedly sleeved on the inner wall of the second filter tube 3. The fixed frame 71 adopts a movable plug-in method to facilitate the removal and cleaning of the large-aperture filter screen 72, and the water outlet pipe 74 serves to transport the polishing liquid after filtration.

[0024] Furthermore, an annular small-aperture filter screen 76 is fixedly sleeved on the inner wall of the annular mounting block 75, a sealing block 77 is fixedly sleeved on the inner wall of the annular small-aperture filter screen 76, and a mounting frame 78 is fixedly connected to the upper surface of the mounting plate 1. The annular small-aperture filter screen 76 serves to intercept and filter fine particle impurities.

[0025] Furthermore, a rotating rod 79 is installed on the inner wall of the mounting frame 78 through a bearing, and a first bevel gear 710 is fixedly sleeved on the outer surface of one end of the rotating rod 79, and the other end of the rotating rod 79 passes through and extends to the lower surface of the sealing block 77. The rotation of the first bevel gear 710 enables the rotating rod 79 to be positioned and rotated through the cooperation between the mounting frame 78 and the bearing.

[0026] Furthermore, the other end of the rotating rod 79 is fixedly connected to a cleaning plate 711, and the upper surface of the cleaning plate 711 is fixedly connected to symmetrically distributed elastic bristles 712, and one end of multiple elastic bristles 712 are in contact with the lower surface of the annular small-aperture filter 76. A servo motor 713 is fixedly installed on the upper surface of the mounting plate 1 through a mounting seat. The rotation of the rotating rod 79 drives the elastic bristles 712 to rotate through the cleaning plate 711, thereby cleaning impurities adsorbed under the annular small-aperture filter 76.

[0027] Furthermore, the output shaft of the servo motor 713 is fixedly installed with a rotating shaft 714 through a coupling, and a second bevel gear 715 is fixedly sleeved on the outer surface of one end of the rotating shaft 714. The tooth surface of the second bevel gear 715 is meshed with the tooth surface of the first bevel gear 710. The servo motor 713 drives the second bevel gear 715 to rotate through the rotating shaft 714, and the rotation of the second bevel gear 715 drives the meshing first bevel gear 710 to rotate.

[0028] Through the automatic cleaning device, when the annular small-aperture filter screen 76 is blocked, the effect of automatic cleaning and unblocking is achieved, thereby solving the problem that the existing filter screen needs to be manually vibrated and cleaned at regular intervals, which not only has a poor cleaning effect, but also is cumbersome to operate, does not make rational use of manual labor, and causes a waste of manpower.

[0029] Working principle: Step 1, add the used polishing liquid into the filter bucket 7, intercept and filter the large particle impurities in the polishing liquid through the large aperture filter 72, so that the small particle impurities and the polishing liquid enter the first filter tube 2, and enter the arc elbow 4 through the first filter tube 2, and then enter the second filter tube 3, and the small particle impurities in the polishing liquid are intercepted by the annular small aperture filter 76 in the second filter tube 3, so that the filtered polishing liquid is discharged through the outlet pipe 74 for reuse;

[0030] Step 2: When the lower surface of the annular small-aperture filter screen 76 absorbs a large number of small particles and causes blockage, the polishing liquid cannot pass through the outlet pipe 74, so that the polishing liquid in the first filter tube 2 is accumulated and the liquid level rises. When the liquid level sensor 73 senses that the liquid level is higher than the preset value, the servo motor 713 is started to work, and the servo motor 713 drives the second bevel gear 715 to rotate through the rotating shaft 714. The rotation of the second bevel gear 715 drives the rotating rod 79 to rotate through the meshing first bevel gear 710;

[0031] Step three, the rotation of the rotating rod 79 is positioned and rotated through the cooperation of the bearing and the mounting frame 78, and drives the cleaning plate 711 to rotate. The rotation of the cleaning plate 711 cleans the small particle impurities adsorbed on the lower surface of the annular small-aperture filter 76 through the cooperation of the elastic bristles 712. The cleaned impurities fall into the drain pipe 5 through the arc-shaped inner wall of the arc-shaped elbow 4 for collection. The impurities can be cleaned by opening the solenoid valve 6 regularly. When the annular small-aperture filter 76 is unblocked, the liquid level in the first filter tube 2 begins to drop. When the liquid level sensor 73 senses that the liquid level is lower than the preset value, the servo motor 713 is turned off.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
