Description

Technical Field

[0001] The utility model relates to the field of crystal processing equipment, in particular to a feeding mechanism for a crystal grinding and polishing machine. Background Art

[0002] At present, most of the machines used for crystal grinding and polishing are fully automatic multi-process surface grinding and polishing machines, which are also equipped with automatic feeding mechanisms. The current feeding mechanism includes a reciprocating sliding material box, in which the crystal blank is placed, and a discharge hole is provided on the bottom surface of the front end of the material box. A template is provided under the material box, and a row of mold holes are provided on the template corresponding to the discharge hole. The sliding of the material box causes the crystal blank to shake, and causes the crystal blank to fall from the discharge hole into the mold hole. This type of feeding device needs to shake continuously for a period of time to ensure that there is crystal blank entering each mold hole, and the feeding efficiency is not high. At the same time, the sewage generated by the grinding and polishing machine during the processing process is easily gathered on the template with the operation of the equipment, affecting the smooth entry of the crystal blank into the mold hole, resulting in unstable feeding of the crystal blank by the equipment.

[0024] 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 of 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.

[0025] See also Figure 1 The utility model provides a feeding mechanism for a crystal grinding and polishing machine, including a frame 1, a template 11 is fixed on the frame 1, a plurality of mold holes 111 are provided on the template 11, and a feed port 112 is provided on one side of the mold hole; a material table 2 is obliquely arranged above the frame 1, a plurality of feed troughs 21 are provided on the material table 2, and the ends of the feed troughs 21 are connected to the feed port 112; a material box 3, the material box 3 can slide back and forth relative to the material table 2, and a plurality of discharge holes are provided on the lower surface of the material box 3, and the discharge holes are located above the feed troughs 21.

[0026] When the mechanism is in use, the material box 3 slides back and forth, causing the crystal blank inside to shake and fall into the feed trough 21 from the discharge hole. The material table 2 is tilted, and the crystal blank continues to slide along the feed trough 21 under the action of gravity until it slides into the mold hole 111 through the feed port 112. At the same time, the sewage on the material table 2 will automatically flow out under the action of gravity, ensuring the dryness of the surface of the material table 2. In the working state, the material box 3 maintains continuous reciprocating sliding, and the crystal blanks that fall out are arranged in the feed trough 21. When the crystal blanks in the mold hole 111 are transported away, the crystal blanks in the feed trough 21 can immediately enter the mold hole 111 without waiting for the material box 3 to unload, thereby improving the feeding efficiency of the crystal blanks.

[0027] like Figure 4 As shown, a lifting bar 22 is provided between adjacent feed troughs 21, and an anti-slip sheet 23 is fixed on the lifting bar 22. The anti-slip sheet 23 partially covers the top of the feed trough 21, and the anti-slip sheet 23 is used to prevent the crystal blank from falling out of the feed trough 21, thereby ensuring the normal feeding of the crystal blank.

[0028] like Figure 2 As shown, an adjusting rod 24 is hinged at each corner of the material platform 2, an adjusting plate 12 is fixed on the frame 1, and a plurality of adjusting holes 121 are provided on the adjusting plate 12. The adjusting rod 24 can be fixed in the adjusting holes 121 at different positions, so as to achieve the effect of adjusting the inclination angle of the material platform 2.

[0029] like Figure 2 As shown, linkage blocks 25 are rotatably connected on both sides of the material platform 2, linkage rods 251 and synchronization rods 252 are fixed between the linkage blocks 25, extension pieces 253 are fixed on the linkage rods 251, the linkage rods 251 and the extension pieces 253 are both located above the material platform 2, a plurality of spaced-apart pressing pieces 254 are provided at the ends of the extension pieces 253, the pressing pieces 254 are located between the anti-slipping pieces 23, the synchronization rods 252 are located below the material platform 2, and the synchronization rods 252 are located below the material platform 2. The step rod 252 is connected with a material pressing driving cylinder 255, which is arranged on the frame 1. The material pressing driving cylinder 255 can push the linkage block 25 to rotate, and at the same time drive the positioning piece to move toward the gap between the anti-slip pieces 23. When the end of the positioning piece enters the feed trough 21, the positioning piece can position the crystal blank in the feed trough 21 to avoid the crystal blank in the feed trough 21 from piling up at the feed port 112 of the mold hole 111, thereby ensuring that the crystal blank is fed in an orderly manner.

[0030] like Figure 1As shown, the frame 1 is provided with a feeding swing cylinder 31, and the material box 3 is connected to the end of the feeding swing cylinder 31. The feeding swing cylinder 31 pushes the material box 3 to move in the downward direction of the crystal blank. Guide rods 32 are fixed on both sides of the material table 2, and the material box 3 is slidably connected to the guide rods 32. A spring 33 is provided between the material box 3 and the material table 2, and the spring 33 is used for the retraction of the material box 3. The retraction force provided by the spring 33 is softer than that of the cylinder, especially when the crystal blank is stuck between the material box 3 and the feed trough 21, damage to parts or blanks caused by forced pulling can be avoided.

[0031] like Figure 2 , 3 As shown, the linkage block 25 is L-shaped, the synchronization rod 252 is fixed to one end of the linkage block 25, the other end of the linkage block 25 is rotatably connected to the material table 2, and the linkage rod 251 is arranged in the middle of a straight side on the linkage block 25.

[0032] like Figure 4 As shown, the material platform 2 is penetrated by a plurality of strip holes 211, and the strip holes 211 are located at the middle and low positions of the feed trough 21. The sewage, impurities or smaller waste materials on the material platform 2 can be discharged through the strip holes 211, thereby improving the drainage effect of the material platform 2 and ensuring the dryness of the surface of the material platform 2.
