DETAILED DESCRIPTION

[0026] The following is combined with Figure 1-9 The embodiments of the present invention are described in detail.

A driver 104 and a bearing seat 105 are provided on the frame 1. The driver 104 and the bearing seat 105 are located at the same height. The driving shaft 201 is installed in the driver 104. The driver 104 is a servo motor, which is used to drive the driving shaft 201 to rotate, thereby driving the polishing barrel 205 to rotate as a whole. The rotating shaft 202 is installed in the bearing seat 105.

[0029] A chassis 6 is provided on one side of the frame 1, and a powder supply mechanism 7 is provided on the upper part of the chassis 6. The powder supply mechanism 7 includes a base 701 installed on the chassis 6, a supply pipe 702 is provided on the upper part of the base 701, a pipe cover 724 is provided on the upper part of the supply pipe 702, a powder inlet 725 is provided in the middle of the pipe cover 724, a feed block 705 is provided at the bottom of the supply pipe 702, a feed notch 717 is provided on the feed block 705, a central axis 707 is rotatably provided in the middle of the feed block 705, a rotating disk 706 is connected to the upper end of the central axis 707, the bottom of the rotating disk 706 is arranged to fit the top of the feed block 705 to prevent powder from entering the gap between the two, and a plurality of powder loading through holes 720 are provided on the rotating disk 706. The distance from the center of circle 720 to the center of circle of rotating disk 706 is the same as the distance from the center of feeding notch 717 to the center of circle of rotating disk 706. The size of powder loading hole 720 is not larger than the size of feeding notch 717. Positioning tube 1 714 is provided in the feeding tube 702 at a position above feeding notch 717. The top of positioning tube 1 714 is connected to the bottom of tube cover 724. A blocking block 715 is provided at the lower part of positioning tube 1 714. A part of blocking block 715 is extended into positioning tube 1 714. A first spring 716 is provided inside positioning tube 1 714. One end of the first spring 716 abuts against the bottom of tube cover 724 and the other end abuts against the top of blocking block 715. The size of the bottom of blocking block 715 is larger than the size of powder loading hole 720.

[0030] The lower end of the central shaft 707 passes through the base 701 and is connected to a synchronous wheel 709. A powder supply motor 718 is provided on the base 701. A motor cover 703 is provided outside the powder supply motor 718. The powder supply motor 718 is driven and connected to a driving flywheel 704. A synchronous belt 710 is connected between the driving flywheel 704 and the synchronous wheel 709. A powder supply tee 719 is provided below the base 701. The upper part of the vertical section of the powder supply tee 719 is inserted from bottom to top into the feed notch 717. The powder supply tee 719 is arranged inside, one end of the horizontal section of which is connected to the air pump 602 arranged at the bottom of the chassis 6, and the other end is connected to the powder supply pipe 721. The powder supply pipe 721 is arranged away from the end of the powder supply tee 719 and extends into the powder inlet hole 203. The air pump 602 generates negative pressure by doing work, and the powder that enters the powder supply tee 719 through the discharge notch 717 is transported to the polishing barrel 205 through the powder supply pipe 721 and the powder inlet hole 203.

[0031] Polishing powder enters the feeding tube 702 from the powder inlet 725 in the middle of the tube cover 724, falls on the rotating disk 706, and is filled into the powder loading hole 720. The air supply motor 718 drives the flywheel 704 to rotate, and the flywheel 704 drives the synchronous wheel 709 to rotate through the synchronous belt 710, and the synchronous wheel 709 drives the rotating disk 706 to rotate through the central shaft 707. When the powder loading hole 720 on the rotating disk 706 rotates to the blocking block 715, the blocking block 715 presses against the rotating disk 706 under the action of the first spring 716, thereby blocking the powder on the rotating disk 706, and only the powder in the powder loading hole 720 can reach the unloading gap 717, ensuring that the powder supply amount each time is the amount filled in one powder loading hole 720. The positioning tube 1 714 and the material stopper 715 are both hollow, and the tube cover 724 has a through hole corresponding to the top of the positioning tube 1 714, so that the material discharge gap 717 is connected to the outside. The compressor is operated to form a negative pressure in the powder supply pipeline 721, and the powder reaching the material discharge gap 717 is sucked into the powder supply tee 719, and then moves along the powder supply pipeline 721 and enters the polishing barrel 205 through the powder inlet hole 203. When the powder filling through hole 720 supplied with powder is rotated out from the material stopper 715, the powder on the rotating disk 706 will fall into the powder filling through hole 720 to fill it up.

[0032] Preferably, one end of the driving shaft 201 away from the polishing barrel 205 passes through the driver 104 and is connected to the first detection disk 106, on which a plurality of first detection notches 107 are provided, and the driver 104 is provided with a first infrared detector 108 that matches the first detection notches 107. The first infrared detector 108 detects the passage of the first detection notches 107 on the first detection disk 106, and obtains the rotation of the driving shaft 201, thereby obtaining the number of rotations of the polishing barrel 205.

[0033] Preferably, the lower end of the central axis 707 is connected to a second detection disk 711, and a second detection notch 712 is provided on the second detection disk 711. The lower part of the base 701 is provided with a second infrared monitor 713 that matches the second detection notch 712. The number of the second detection notches 712 is the same as the number of the powder-loading through holes 720, and the positions are arranged in a one-to-one correspondence. By detecting the second detection notches 712 with the second infrared monitor 713, the number of the powder-loading through holes 720 passing through the lower powder notch 717 can be obtained, and this number can be multiplied by the powder loading amount of the powder-loading through holes 720 to obtain the total supply of powder.

[0034] Preferably, a dispersion block 708 is provided in the middle position of the upper part of the rotating disk 706. The dispersion block 708 is a truncated cone and the diameter of the upper end is smaller than the diameter of the lower end. After the powder entering the feeding tube 702 from the powder inlet 725 falls on the dispersion block 708, it slides down along the side of the dispersion block 708 and is scattered on the rotating disk 706, thereby preventing the powder from accumulating in the middle of the rotating disk 706 and failing to fill the powder filling hole 720.

[0035] Preferably, a plurality of observation ports 723 are provided on the feed tube 702, and a transparent tube 722 is provided inside the feed tube 702, and the transparent tube 722 covers the observation ports 723. By providing the transparent tube 722 and the observation ports 723, the amount of powder in the feed tube 702 can be observed, and the powder can be replenished in time when the amount is insufficient.

[0036] Preferably, the sealing mechanism 8 includes a fixed cover 801 fixedly mounted on the polishing barrel 205, two baffle rods 802 are passed through the right side of the fixed cover 801, a contact rod is connected to the right side of the baffle rod 802, a guide rod 805 is connected to the left side of the baffle rod 802, the guide rod 805 is arranged through the left side of the fixed cover 801, a movable cover 803 is arranged on the upper part of the baffle rod 802, a positioning tube 804 is arranged on the movable cover 803, a second spring 806 is sleeved on the guide rod 805, one end of the second spring 806 abuts against the left side of the fixed cover 801, and the other end abuts against the left end of the baffle rod 802, and an electric push rod 807 is arranged at the position corresponding to the abutment rod on the frame 1.

[0037] When feeding or discharging, the electric push rod 807 at the upper and lower ends of the corresponding polishing barrel 205 runs, and the electric push rod 807 abuts against the abutment rod to push the stop rod 802 to move leftward, and the stop rod 802 drives the moving cover 803 to move leftward so that the positioning tube 2 804 is aligned with the openings at the upper and lower ends of the polishing barrel 205. At this time, the capsule enters from the opening at the upper end of the polishing barrel 205 for loading or the polishing barrel 205 is discharged from the opening at the lower end for unloading. The size of the positioning tube 2 804 is not larger than the size of the openings at the upper and lower ends of the polishing barrel 205, ensuring that the capsule will not fall from the gap during the feeding process.

[0038] When sealing, the electric push rod 807 retracts, and the gear rod 802 moves to the right and resets under the action of the second spring 806, so that the positioning tube 804 is staggered with the openings at the upper and lower ends of the polishing barrel 205. At the same time, the lower end of the movable cover 803 fits the openings at the upper and lower ends of the polishing barrel 205 to form a seal, ensuring that the internal capsule will not fall out when the polishing barrel 205 rotates.

[0039] The chassis 6 is provided with a touch screen 601 , through which the operating status of each part of the device can be displayed, and each part of the device can also be operated through the touch screen 601 .

[0040] Preferably, one end of the powder supply pipe 721 extends into the polishing barrel 205 and is located in the middle position of the polishing barrel 205. The end of the powder supply pipe 721 located in the polishing barrel 205 is sealed, and a plurality of powder outlet holes 206 are provided on the outer periphery of the part of the powder supply pipe 721 located in the polishing barrel 205, so that the powder can be directly sprayed out from the powder outlet holes 206 in the form of atomization, and can be better mixed with the capsule for polishing.

[0041] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
