Description

Technical Field

[0001] The utility model relates to the technical field of crystal product processing, in particular to a double-sided grinding machine for crystal bottle caps. Background Art

[0002] Crystal bottle caps generally refer to caps made of crystal material, which are usually used to cover or close containers, such as bottles, jars, etc. Crystal bottle caps can be individually made decorative objects, or they can be functional components used with specific containers. The crystal bottle caps are usually positioned by the action of a fixture, and their outer surface is polished by a grinder. After polishing, the crystal bottle caps need to be turned over by a flipping mechanism, and the position can be adjusted again before a second polishing can be performed, thereby completing the double-sided polishing of the crystal bottle caps.

[0003] However, the existing grinding machines require the crystal bottle caps to be turned over before secondary grinding. The turning process easily makes it difficult to calibrate the position of the crystal bottle caps, thereby increasing the difficulty of subsequent grinding and posing a risk of scrapping. In view of this, we propose a double-sided grinding machine for crystal bottle caps. Utility Model Content

A guide rod 12 is arranged in the sliding hole. Both ends of the guide rod 12 are fixedly connected to the controller 2 and the opposite wall of the second vertical plate 10, and cooperate with the sliding hole to guide the first vertical plate 3 in a moving state to avoid deviation of its moving trajectory and affect the subsequent grinding of the crystal bottle caps. The output end of the cylinder 4 is fixedly connected to the other side wall of the first vertical plate 3 to provide power for the lateral movement of the first vertical plate 3.

[0021] Furthermore, an outer surface polishing assembly 6 for polishing the outer surface of the crystal bottle cap is installed on the first vertical plate 3. The outer surface polishing assembly 6 includes a first forward and reverse motor 61. The first forward and reverse motor 61 is fixedly installed on the top wall of the first vertical plate 3. A second limiting slide groove is opened on one side wall of the first vertical plate 3. The first bidirectional threaded rod 62 is arranged in the second limiting slide groove. A first bearing is embedded on the bottom wall of the second limiting slide groove. The inner ring surface of the first bearing is connected to the outer ring surface of the first bidirectional threaded rod 62, which is used to limit the bottom end of the first bidirectional threaded rod 62 and assist the first bidirectional threaded rod 62 to rotate in the second limiting rotation groove; a first rotating hole is opened on the top wall of the second limiting rotation groove, and the top end of the first bidirectional threaded rod 62 passes through the first rotating hole and is connected to the output end of the first forward and reverse motor 61; the first outer surface polishing member 63 and The second outer surface polishing member 64 is provided with a first threaded hole and is symmetrically sleeved on the outer ring surface of the first bidirectional threaded rod 62. The two first anti-slip sliding blocks 65 are symmetrically welded on the two side walls of the first outer surface polishing member 63 and cooperate with the second limiting sliding groove, which is conducive to guiding the first outer surface polishing member 63 in a moving state. By starting the first forward and reverse motor 61 to drive the first bidirectional threaded rod 62, the first outer surface polishing member 63 and the second outer surface polishing member 64 can be driven to move in the same direction or in the opposite direction. The first outer surface polishing member 63 and the second outer surface polishing member 64 in the same direction moving state can clamp the outer ring surface of crystal bottle caps of different sizes, and vice versa, the clamping positioning can be released, so that the polishing surfaces of the first outer surface polishing member 63 and the second outer surface polishing member 64 are in close contact with the outer ring surface of the crystal bottle cap, which is convenient for polishing and grinding its outer ring surface.

[0022] Further, a rotating component 7 that can rotate is arranged in the limit rotation opening opened on the second vertical plate 10, and the rotating component 7 includes a rotating drum 71.

A driving assembly 8 is provided below the rotating assembly 7 for driving the rotating assembly 7 to rotate. The driving assembly 8 includes a servo motor 81, which is mounted on the top wall of the base 1. One end of the rotating shaft 82 is connected to the output end of the servo motor 81. The main gear 83 is located below the rotating drum 71 and is fixedly sleeved on the outer ring surface of the rotating shaft 82. It is also meshed with the driven gear 72, so that when the servo motor 81 drives the rotating shaft 82 to rotate, the main gear 83 transmits the driven gear 72, thereby achieving the purpose of driving the rotating drum 71 to rotate and providing power for the subsequent polishing of the crystal bottle cap.

[0023] Furthermore, the rotating assembly 7 is equipped with an inner surface grinding assembly 9 for grinding the inner surface of the crystal bottle cap. The inner surface grinding assembly 9 includes a second forward and reverse motor 91, which is fixedly mounted on the top wall of the rotating drum 71. A second bidirectional threaded rod 92 is arranged in an adjusting cavity in the rotating drum 71. The top end of the second bidirectional threaded rod 92 is connected to the output end of the second forward and reverse motor 91. A second bearing is sleeved on the outer ring surface at the bottom end of the second bidirectional threaded rod 92. The second bearing is installed in an embedded state in a recessed part of the inner surface wall of the rotating drum 71 to assist the second bidirectional threaded rod 92 in rotation and positioning; a second threaded hole is provided on the first inner surface grinding piece 93 and the second inner surface grinding piece 94, and the two are symmetrically sleeved on the outer ring surface of the second bidirectional threaded rod 92 through the second threaded hole. Two second anti-slipping sliders 95 are symmetrically welded on the two side walls of the first inner surface grinding piece 93. Guide grooves are symmetrically provided on the inner surface wall of the rotating drum 71. The two second anti-slipping sliders 95 are respectively arranged at positions In the corresponding guide groove, the first inner surface polishing member 93 in the moving state is guided by the cooperation of the guide groove and the second anti-slip sliding block 95. When the second forward and reverse motor 91 drives the second bidirectional threaded rod 92 to drive the first inner surface polishing member 93 and the second inner surface polishing member 94 to move in opposite directions, the crystal bottle cap inserted on the first inner surface polishing member 93 and the second inner surface polishing member 94 can be propped up and positioned. At this time, the first outer surface polishing member 63 and the second outer surface polishing member 64 can be kept in a relaxed state. With the drive of the driving component 8, the rotating component 7 can drive the inner surface polishing component 9 to rotate, so that the crystal bottle cap can rotate before the inner surface polishing component 9 is limited, and the first outer surface polishing member 63 and the second outer surface polishing member 64 are set to achieve the purpose of polishing its inner surface wall, so that there is no need to flip the crystal bottle cap, avoid position deviation during the flipping process, affect the quality of the finished product, and save the flipping step, which is conducive to improving the polishing speed and providing convenience for the polishing processing of the crystal bottle cap.
