Description

Technical Field

[0001] The utility model belongs to the technical field of burr trimming of lamp shades, and particularly relates to a burr trimming device for the edge of a lamp shade. Background Technique

[0002] A lamp shade is a cover used to concentrate light or protect against wind and rain around the flame or on the bulb. The lamp shade not only serves to gather light together but also prevents electric shock and has a role in protecting the eyes. The burrs on the edge of the lamp shade refer to the tiny, sharp metal or plastic protrusions generated on the edge during the manufacturing process of the lamp shade, especially after the stamping or cutting steps. These burrs are usually caused by plastic deformation and mechanical stress during the processing of materials. They not only affect the appearance quality of the product but also may pose safety hazards to users. The edge of the lamp shade usually refers to the opening part of the lamp shade, that is, the edge area in contact with the outside world.

[0003] However, most of the current lamp shade burr trimming devices are not convenient to adjust during the trimming of edge burrs, resulting in poor removal effect of the lamp shade burrs. Moreover, trimming the burrs with a scraper may cause scratches of different depths on the edge of the lamp shade, and safety problems such as scratches may occur during installation and use.

A connecting rod 81 is fixedly connected to the lower surface of the first rotating shaft 8. The upper surface of the downward pressing suction cup 82 is fixedly connected to one end of the connecting rod 81. There is an empty groove at one end of the bearing rod 5. A first motor 11 is provided in the empty groove. The output shaft of the first motor 11 is connected to a second rotating shaft 12. The second rotating shaft 12 is rotatably installed on the upper surface of the bearing rod 5. The lampshade bearing block 13 is fixedly installed at the center of the second rotating shaft 12.

[0030] Among them, by inserting the screwing screw 3 into one end of the lower pressing plate 7 and threadedly connecting the screwing screw 3 into the threaded hole provided on the fixing plate 2, then rotating the screwing screw 3 to adjust the distance between the lower pressing plate 7 and the lamp cover, so that the lower pressing suction cup 82 provided at one end of the lower surface of the lower pressing plate 7 closely adheres to the upper surface of the lamp cover, which can prevent the lamp cover from shifting during the trimming process and improve the stability during trimming. After trimming one side of the lamp cover, the first motor 11 drives the second rotating shaft 12, so that the second rotating shaft 12 drives the lamp cover bearing block 13 fixedly installed on the upper surface to rotate, and the lamp cover pressed on the lamp cover bearing block 13 rotates together. During the rotation, the lower pressing suction cup 82 attached to the upper surface of the lamp cover rotates through the first rotating shaft 8 rotatably installed on the lower surface of the lower pressing plate 7, and there will be no phenomenon of rotation jamming, which can effectively adjust the orientation. Then, the trimming assembly 6 trims the remaining side of the lamp cover. The trimming assembly 6 can evenly process the entire edge of the lamp cover and can adapt to lamp covers of various shapes and sizes, improving the applicable range and flexibility during adjustment.

[0031] See attached Figure 4 to attached Figure 6 As shown, the trimming assembly 6 includes a second motor 601, and the second motor 601 is arranged on one side of the trimming table 4. The same sliding grooves 602 are provided on both sides of the trimming table 4. A slider 604 is slidably installed in the sliding groove 602. One end of one of the two groups of sliders 604 is provided with a second threaded hole, and a lead screw 603 is threadedly connected in the second threaded hole. The output shaft of the second motor 601 is connected to one end of the lead screw 603. Connecting blocks 605 are fixedly installed on one side of the sliders 604. One end of the connecting block 605 is provided with a third threaded hole, and an adjustable distance threaded rod 606 is threadedly connected in the third threaded hole. The other end of the adjustable distance threaded rod 606 is fixedly connected to a mounting plate 608, and a first sponge sandpaper 609 is provided on the surface of one end of the mounting plate 608. A linkage plate 610 is fixedly connected between the two groups of sliders 604. A burr scraper 607 is fixedly installed on the upper surface of the linkage plate 610. The burr scraper 607 is inclined. A long-shaped empty groove is provided at the other end of the upper surface of the linkage plate 610, and a second sponge sandpaper 611 is provided in the long-shaped empty groove.

[0032] Among them, the second motor 601 drives the lead screw 603 to run, enabling the slider 604 to drive the burr scraper 607 provided at one end to clean the burrs on the edge of the lampshade. The distance between the trimming table 4 and the lampshade is adjusted in advance by the electric push rod 9. Moreover, the burr scraper 607 is inclined, and when the burr scraper 607 moves, it can effectively scrape and remove the burrs on the lampshade. The surface polishing work is carried out by the second sponge sandpaper 611 provided at one end of the burr scraper 607, thereby reducing the scratches caused when removing the burrs. Through the connecting blocks 605 provided at both ends of the slider 604 and the distance-adjusting threaded rod 606 threadedly connected to one end of the connecting block 605, the staff rotates the distance-adjusting threaded rod 606 to adjust the distance between the mounting plate 608 connected to one end and the lampshade, so that the first sponge sandpaper 609 provided at one end of the mounting plate 608 fits on both sides of the lampshade surface, and follows the slider 604 to move to polish both sides of the lampshade for removing burrs in other parts, thus improving the quality of burr removal.

[0033] Working principle: Place the lampshade to be trimmed on the lampshade bearing block 13. Then, insert the screwing screw 3 into one end of the lower pressing plate 7, and then thread the screwing screw 3 into the threaded hole provided on the fixing plate 2. Then rotate the screwing screw 3 to adjust the distance between the lower pressing plate 7 and the lampshade, so that the lower pressing suction cup 82 provided at one end of the lower surface of the lower pressing plate 7 closely adheres to the upper surface of the lampshade, fixing the lampshade between the lower pressing suction cup 82 and the lampshade bearing block 13. Then, through the telescopic movement of the electric push rod 9, the linkage block 10 connected to the piston rod drives the trimming table 4 to lift and lower, adjusting the distance from the lampshade, so that the burr scraper 607 is placed on the lower surface of the lampshade, facilitating the burr trimming and removal work. After the distance adjustment is completed, the staff rotates the distance-adjusting threaded rod 606 threadedly connected to the connecting block 605 to adjust the distance between the mounting plate 608 and the lampshade, so that the first sponge sandpaper 609 on the surface of the mounting plate 608 fits on both sides of the lampshade surface. Then, start the second motor 601 to drive the lead screw 603 to run, so that the slider 604 threadedly connected to the lead screw 603 can drive the burr scraper 607 provided at one end and the first sponge sandpaper 609 attached to both sides of the lampshade to move linearly, cleaning and polishing the burrs on the edge and both sides of the lampshade. When scraping, the first sponge sandpaper 609 provided at one end of the burr scraper 607 polishes the edge of the scraped lampshade to avoid the burr scraper 607 causing scratches on the lampshade. After that, start the first motor 11 to drive the second rotating shaft 12, so that the second rotating shaft 12 drives the lampshade bearing block 13 fixedly installed on the upper surface to rotate, and the placed lampshade rotates accordingly to adjust the trimming direction.
