Description

Technical Field

[0001] This utility model relates to the field of crystal processing equipment, and in particular to a multi-row feeding mechanism. Background Technology

[0002] Crystal products need to be polished to make the surface clear. To facilitate the transfer of blanks, the crystal blanks need to be arranged neatly in a straight line before polishing. The current feeding mechanism can only prepare one row of blanks at a time, which is not efficient. At the same time, the feeding mechanism cannot perform initial screening of broken and defective blanks, which causes defective blanks to flow into subsequent processing steps, affecting the overall processing efficiency of the machine.

[0024] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model proposes a multi-row feeding mechanism, see reference. Figure 1 , 3 The feeding mechanism includes a frame 1, on which a movable frame 11 is slidably connected. A first drive mechanism 12 is provided between the frame 1 and the movable frame 11, which pushes the feeding mechanism to a subsequent transfer mechanism. A feeding plate 2 is fixed on the movable frame 11. Several storage troughs 21 are arranged in a matrix on one side of the feeding plate 2. The storage troughs 21 are used to hold blanks. The bottom of the storage troughs 21 is provided with screening holes 22. During the feeding process, the crushed blanks fall out of the screening holes 22, thus ensuring that only blanks of the correct size remain in the storage troughs 21. In addition, a pin in the transfer mechanism can extend into the screening holes 22 to lift the blanks in the storage troughs 21 upwards, thereby assisting in the material transfer.

[0027] This feeding mechanism also includes a material box 3 for storing blanks. The material box 3 is slidably connected to the feeding plate 2. The lower surface of the material box 3 has an opening 31. The opening 31 is close to the feeding plate 2, and a gap can still be left between the opening 31 and the surface of the feeding plate 2, but the height of the gap cannot exceed the thickness of the blank to prevent the blank from falling out. A second drive mechanism 32 is provided between the material box 3 and the frame 1. During the feeding process, this feeding mechanism first drives the material box 3 to slide back and forth on the feeding plate 2 through the second drive mechanism 32. The blank in the material box 3 falls into the storage tank 21 through the opening 31. The back-and-forth movement of the material box 3 can also flatten the blank in the storage tank 21, which is convenient for the subsequent transfer mechanism to pick up. After the blank is dropped, the first drive mechanism 12 pushes the material box 3 and the moving frame 11 together to the bottom of the transfer mechanism.

[0028] See Figure 3 In Example 1, taking a three-row storage tank 21 as an example, a single feeding can provide three rows of materials for the common transfer mechanism to suck up the material, while the material dropping time consumed by the material box is the same as that of the existing single-row feeding mechanism, thereby improving the feeding efficiency. Figure 4 As shown in Example 2, two sets of feeding mechanisms are arranged opposite each other on both sides of the transfer mechanism. This significantly improves the feeding efficiency. Specifically, the feeding mechanisms on both sides can provide blanks to the transfer mechanism in sequence, avoiding transfer interruptions caused by waiting for the material box to be fed, and ensuring the continuous operation of the transfer mechanism.

[0029] See Figure 1 , 2 The frame 1 is provided with a first slide rail 13, the bottom surface of the movable frame 11 is provided with a first slider 14, the first slider 14 is slidably connected to the first slide rail 13, the upper surface of the movable frame 11 is provided with a second slide rail 15, and the two ends of the material box 3 are provided with second sliders 34, the second sliders 34 are slidably connected to the second slide rail 15. Multiple first sliders 14 and second sliders 34 can be provided to ensure the sliding stability of the movable frame 11 and the material box 3.

[0030] See Figure 2 The first drive mechanism 12 includes a first drive motor 121, a drive screw 122, and a screw nut 123. The first drive motor 121 is fixed on the frame 1. The screw nut 123 is fixedly connected to the movable frame 11. The screw nut 123 is sleeved on the drive screw 122. The motor shaft of the first drive motor 121 is fixed to the drive screw 122. The first drive motor 121 drives the drive screw 122 to rotate, and the movable frame 11 slides back and forth through the screw drive.

[0031] See Figure 1 , 2The frame 1 is provided with a vertical plate 16. The second drive mechanism 32 includes a second drive motor 321 fixed on the vertical plate 16. The second drive motor 321 is provided with an output shaft. The end of the output shaft is provided with a drive block 322. The second drive motor 321 drives the drive block 322 to rotate. A drive rod 324 is slidably connected to the vertical plate 16. The drive block 322 can be cam-like in shape. The drive block 322 pushes the drive rod 324 to extend, thereby pushing the material box 3 towards the storage tank 21. A return spring 35 is provided between the moving frame 11 and the material box 3. When the drive rod 324 retracts, since there is no connection between the drive rod 324 and the material box, the pull-back of the material box 3 must be achieved through the return spring 35, thereby cyclically realizing the reciprocating sliding of the material box 3.

[0032] See Figure 2 The drive block 322 is a long strip-shaped block. The output shaft is fixed to one end of the drive block 322. A connecting rod 323 is hinged between the drive block 322 and the drive rod 324. The hinge position of the connecting rod 323 and the drive block 322 is set away from the output shaft. If the output shaft is taken as the center of rotation, the hinge position of the connecting rod 323 is located in an eccentric position. When the second drive motor 321 drives the drive block 322 to rotate, the drive rod 324 can achieve telescopic movement by being pulled by the connecting rod 323.

[0033] See Figure 2 The material box 3 is provided with support frames 33 at both ends. A crossbar 36 is fixed on the support frame 33. The crossbar 36 is located between the material box 3 and the drive rod 324. When the drive rod 324 extends, it contacts the crossbar 36, thereby pushing the material box 3 to move as a whole. The material box 3 itself is relatively fragile. If it directly contacts the drive rod 324, it is easy to break. The two ends of the return spring 35 are respectively connected to the moving frame 11 and the support frame 33.

[0034] See Figure 5 A vibration motor 23 is fixed on the bottom surface of the feeding plate 2. An eccentric block is fixed on the output shaft of the vibration motor 23. When the eccentric block rotates at high speed, the vibration generated by the vibration motor 23 will drive the feeding plate 2 to vibrate synchronously. The vibration motor is a standard product and can be purchased directly. The vibration motor 23 is particularly useful when feeding non-circular billets, as it can facilitate the movement of the billets and speed up the falling of the billets into the storage tank 21. At the same time, the vibration can also straighten the billets in the storage tank 21, which is convenient for subsequent processing of the billets.

All technical solutions that fall within the scope of the present utility model are protected by the present utility model.
