Description

Technical Field

[0001] The utility model belongs to the technical field of glass bead grinding and polishing, and more specifically, particularly relates to a glass bead grinding and polishing device. Background Art

[0002] Glass beads are a common jewelry accessory, widely used in clothing, evening gowns, shoes, hats, handbags, headwear, wool textiles, bead embroidery, lighting, handicrafts, etc. They are composed of silicon dioxide. The surface of glass beads needs to be polished after production. After grinding the rough surface of the glass beads, the surface of the glass beads becomes smoother and more transparent, which improves the look and feel of the glass beads.

[0003] Based on the above, the following problems were found: the existing polishing device usually places multiple glass beads inside the polishing device for polishing. During polishing, the glass beads are prone to collide with each other, resulting in scratches on the surface of the glass beads. After polishing, some tiny gaps will still remain, resulting in lower quality of the glass beads.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a glass bead grinding and polishing device is provided to achieve a more practical purpose. Utility Model Content

[0026] Example:

[0027] As attached Figure 1 To Attachment Figure 5 As shown:

[0028] The utility model provides a glass bead grinding and polishing device, comprising a base 1, a supporting platform 2 is fixed on the top of the base 1, a grinding sandpaper 6 is detachably installed on the top of the supporting platform 2, a supporting rod 7 is fixed at one end of the supporting platform 2, a collecting box 16 is slidably connected to the other end of the supporting platform 2, an electric telescopic rod 8 is fixed to one side of the top of the supporting rod 7, a moving box 9 is fixed to the power output end of the electric telescopic rod 8, a cover plate 10 is hinged on one side of the top of the moving box 9, a telescopic sleeve rod 13 is fixed to the middle part of the bottom of the cover plate 10, an extrusion plate 11 is fixed to the bottom end of the telescopic sleeve rod 13, a spring 14 is provided on the outer wall of the telescopic sleeve rod 13, and a feeding plate 15 is fixed to the other side of the top of the moving box 9.

[0029] Among them, the maximum length value of the telescopic sleeve 13 is greater than the height value of the moving box 9, the top end of the spring 14 is fixed to the cover plate 10, and the bottom end of the spring 14 is fixed to the extrusion plate 11. The extrusion plate 11 and the moving box 9 are used in conjunction with each other. The elastic force is released by the spring 14, so that the extrusion plate 11 is always located at the bottom of the moving box 9. The moving box 9 is in the shape of a hollow rectangular block, so that when glass beads are poured into the moving box 9, the spring 14 pushes the extrusion plate 11 so that the glass beads fit tightly to the top of the grinding sandpaper 6.

[0030] Among them, the feed plate 15 is arranged in an inclined shape, and the inclination angle between the horizontal planes of the feed plate 15 is less than 30 degrees. The top of the cover plate 10 and the feed plate 15 are mutually engaged, and the glass beads to be processed are poured from the feed plate 15. At the same time, the cover plate 10 is opened so that the glass beads can fall to the bottom of the moving box 9. The amount of glass beads poured depends on the size of the moving box 9, so that the glass beads can be spread flat on the bottom of the moving box 9. The inclination angle of the feed plate 15 is small, which reduces the speed of pouring the glass beads.

[0031] Among them, both ends of the bottom of the moving box 9 parallel to the support platform 2 are rotatably connected with rollers 12, the height of the rollers 12 is less than 5 mm, and the bottom of the rollers 12 is arranged to fit the top of the support platform 2. The bottom of the moving box 9 is supported by the rollers 12 to prevent the moving box 9 from directly touching the grinding sandpaper 6 when moving.

[0032] Among them, a guide plate 17 is fixed to the inner wall of the collection box 16 close to the support platform 2, and the guide plate 17 is set in an inclined shape. After polishing is completed, the electric telescopic rod 8 is controlled to extend to the longest, driving the moving box 9 to move to the top of the collection box 16, and the polished glass beads enter the collection box 16 along the guide plate 17.

[0033] Among them, placement grooves 3 for placing grinding sandpaper 6 are opened on both sides of the top of the supporting platform 2, and threaded rods 4 are threadedly connected on both sides of the bottom of the supporting platform 2. The top of the threaded rod 4 is rotatably connected with an extrusion rod 5 for cooperating with the supporting platform 2 to fix the grinding sandpaper 6. The grinding sandpaper 6 is laid flat on the top of the supporting platform 2, and the extrusion rod 5 is used to limit the flattened grinding sandpaper 6 to prevent bulging of the grinding sandpaper.

[0034] Among them, the tops of both sides of the supporting platform 2 are both L-shaped, and the two ends of the grinding sandpaper 6 are respectively located on the tops of the two extrusion rods 5. When the grinding sandpaper 6 needs to be replaced after long-term use, the threaded rod 4 is rotated to drive the extrusion rod 5 to move downward, and then the old grinding sandpaper 6 is removed, and then the new grinding sandpaper 6 is placed on the top of the supporting platform 2 and the two ends of the grinding sandpaper 6 are placed in the placement groove 3, and the threaded rod 4 is rotated to use the extrusion rod 5 to squeeze and limit the two ends of the grinding sandpaper 6.

[0035] The specific usage and function of this embodiment are as follows:

[0036] In the utility model, the cover plate 10 is first separated from the feed plate 15, and the glass beads to be processed are poured from the feed plate 15, and the glass beads fall on the bottom of the moving box 9. The number of glass beads poured depends on the size of the moving box 9. The glass beads are spread flat on the bottom of the moving box 9. The feed plate 15 is set with a small inclination angle, which reduces the speed of pouring the glass beads and reduces the impact force of the glass beads. Then, the cover plate 10 is buckled and connected to the feed plate 15. The spring 14 releases the elastic force to push the extrusion plate 11 so that the glass beads are closely attached to the top of the grinding sandpaper 6, and then the electric telescopic rod 8 is controlled to extend and retract, which can drive the glass beads to rub and grind on the top of the grinding sandpaper 6. The roller shaft 12 supports the bottom of the moving box 9 to prevent the moving box 9 from directly touching the grinding sandpaper 6 when moving. After grinding, the electric telescopic rod 8 is controlled to extend to the longest, driving the moving box 9 to move to the top of the collecting box 16, and the polished glass beads enter the collecting box 16 along the guide plate 17. When the grinding sandpaper 6 needs to be replaced after long-term use, the threaded rod 4 is rotated to drive the squeezing rod 5 to move downward, and then the old grinding sandpaper 6 is removed, and then the new grinding sandpaper 6 is placed on the top of the supporting platform 2 and the two ends of the grinding sandpaper 6 are placed in the placement groove 3, and the threaded rod 4 is rotated to use the squeezing rod 5 to squeeze and limit the two ends of the grinding sandpaper 6.
