DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0036] See also Figure 1-6 As an embodiment of the utility model, a device for polishing the edge of an easy-pull bottle cap comprises a workbench 1, a feeding tray 2 is rotatably provided on the top of the workbench 1, a plurality of workstations 3 are provided on the feeding tray 2 at equal intervals along the circumference, a polishing wheel 24 is also provided on the workbench 1, and the polishing wheel 24 is connected to a driving device, and the driving device can drive the polishing wheel 24 to rotate so as to polish the easy-pull bottle cap in the workstation 3;

[0037] A power structure is also provided between the driving device and the workbench 1, and the power structure is used to drive the polishing wheel 24 and the driving device to reciprocate alternately;

[0038] The power structure is also connected to the feeding tray 2, so that after the polishing wheel 24 moves upward to separate from the easy-pull bottle cap, the feeding tray 2 is driven to rotate and switch the workstation 3;

[0039] The driving device is also provided with a positioning structure, which fixes the feeding tray 2 at the current work station 3 when the polishing wheel 24 moves downward to approach the easy-pull bottle cap.

[0040] The polishing wheel 24 is driven to rotate at a high speed by the driving device. When the power structure drives the polishing wheel 24 to move downward to the lowest point of its travel, the high-speed rotating polishing wheel 24 can polish and grind the pop-top bottle cap located below it; after the polishing is completed, the power structure drives the polishing wheel 24 to be lifted and separated from the pop-top bottle cap after polishing; after the polishing wheel 24 is separated from the pop-top bottle cap, the power structure is used to drive the feeding tray 2 to rotate a certain angle to switch the workstation 3, so that the next pop-top bottle cap to be processed rotates to the bottom of the polishing wheel 24;

[0041] Then the power structure drives the polishing wheel 24 to move downward to the lowest point of its stroke again, and polishes it, and the continuous processing of multiple easy-pull bottle caps is completed in this reciprocating manner.

[0042] like Figure 5 As shown, the power structure includes a first motor 16, the output end of the first motor 16 is fixedly connected to a turntable 19, and a track groove 20 is opened on the turntable 19. The power structure also includes a fixed seat for mounting the driving device, and a moving shaft 22 and a slider 23 are fixedly connected to the fixed seat. The moving shaft 22 is slidably connected to the inside of the track groove 20;

[0043] The track groove 20 includes a small arc and a large arc, and the arc is connected to the large arc.

[0044] The first motor 16 drives the turntable 19 to rotate. When the turntable 19 rotates, the track groove 20 on it will also rotate and change its angle, and the moving shaft 22 will slide along the track inside the track groove 20. Initially, the moving shaft 22 is located in the small arc. As the turntable 19 continues to rotate, the moving shaft 22 will move to the connection between the small arc and the large arc, and then enter the large arc through the guidance of the connection. When entering the large arc, the moving shaft 22 will slide outward. Similarly, when entering the small arc from the large arc, the moving shaft 22 will slide inward, thereby driving the driving device to perform a short-distance reciprocating motion.

[0045] Through the design of large arcs and small arcs in the track groove 20, the driving device can be driven to reciprocate when the turntable 19 rotates. Compared with the traditional cylinder drive, the overall purpose is achieved completely through the cooperation of the mechanical structure while reciprocating. The rising and falling time is fixed, and there will be no problem of affecting the polishing accuracy due to untimely control or damage to electronic components, and the processing is more precise.

[0046] like Figure 4 As shown, the power structure also includes a fixed frame 13 fixedly connected to the top of the workbench 1, a guide plate 14 is fixedly connected to the fixed frame 13, a guide groove 15 is provided on the guide plate 14, and a moving shaft 22 and a slider 23 are both slidably connected inside the guide groove 15;

[0047] When the moving shaft 22 slides inside the track groove 20 , the guide groove 15 limits the sliding direction of the slider 23 .

[0048] When the turntable 19 rotates to drive the driving device to slide, the moving shaft 22 and the sliding block 23 on the fixed seat will slide along the guide groove 15.

[0049] Through the design of the guide plate 14 and the guide groove 15, the movable shaft 22 and the slider 23 can only slide in a limited direction along the limit of the guide groove 15, so that the drive device can be installed to run in the required direction, avoiding movement deviation or dislocation and improving processing stability.

[0050] like Figure 2 As shown, a worm gear 4 is fixedly connected to the corner of the feed tray 2, a feed pipe 8 is fixedly connected to one side of the top of the workbench 1, a material guide frame 6 is fixedly connected to the bottom of the workbench 1, and the depth of the station 3 is slightly lower than the thickness of the easy-pull bottle cap;

[0051] The easy-pull bottle caps are regularly stacked and placed inside the feed tube 8. When the feed tray 2 rotates, the workstation 3 docks with the feed tube 8, and the bottle caps inside the feed tube 8 fall into the workstation 3. Then the feed tray 2 continues to rotate, and another bottle cap is blocked by the top of the feed tray 2. Then the workstation 3 with the bottle cap rotates to the polishing wheel 24 for polishing. After polishing is completed, the feed tray 2 continues to rotate to switch the workstation 3. The workstation 3 rotates to the discharge point and is slid out through the guide frame 6.

[0052] By making the depth of station 3 slightly lower than the thickness of the easy-pull bottle cap, when the bottle cap falls into station 3, since the bottle cap is higher than the station, the bottle caps stacked above will continue to be supported by the bottle caps in station 3 and will not fall, thereby preventing repeated loading. The whole process is automated, and both loading and unloading are simple and convenient.

[0053] like Figure 2 and 3 As shown, a rotating shaft is fixedly connected to the middle of the workbench 1, and the feeding tray 2 is rotatably connected to the rotating shaft;

[0054] The workbench 1 is also provided with a discharge port 5 adapted to the work station 3, and a material guide frame 6 is connected to the discharge port 5;

[0055] A first mounting frame 7 is also fixedly connected to one side of the top of the workbench 1 , and a feeding pipe 8 is fixedly connected to the first mounting frame 7 .

[0056] The feeding tray 2 rotates along the rotating shaft to switch the workstation 3. When the workstation 3 switches to the discharge port 5, the bottom of the workstation 3 loses its limit and then falls into the discharge port 5 and is discharged through the guide frame 6.

[0057] like Figure 3As shown, the workbench 1 is fixedly connected to a second mounting frame 9, the second mounting frame 9 is rotatably connected to a shaft 10, the shaft 10 is respectively provided with a half toothed disc 12 and a first belt pulley 11, the first motor 16 is also sleeved with a second belt pulley 17, a belt 18 is tensioned on the first belt pulley 11 and the second belt pulley 17, and the half toothed disc 12 is meshed with the worm rack 4;

[0058] The half toothed disc 12 is a half worm gear structure. When the half toothed disc 12 is engaged with the worm gear 4, it drives the feed tray 2 to rotate. When it rotates to the other half, it loses engagement with the worm gear 4, the half toothed disc 12 continues to rotate, and the feed tray 2 does not move.

[0059] The first motor 16 rotates to drive the second pulley 17 to rotate, and the second pulley 17 drives the first pulley 11 to rotate through the belt 18. The first pulley 11 rotates to drive the shaft 10 to rotate, thereby driving the half toothed disc 12 to rotate and engage with the worm rack 4.

[0060] Through the design of the half toothed disc 12, the feed tray 2 can perform intermittent fixed-distance movements during the continuous rotation of the first motor 16. No additional driving equipment is required and the use of the first motor 16 is not affected. The overall production cost is low, and the stability is enhanced through the connection of the mechanical structure.

[0061] like Figure 5 As shown, the driving device includes a second motor 21 fixedly connected to a fixed seat, and a polishing wheel 24 is fixedly connected to an output end of the second motor 21 .

[0062] like Figure 6 As shown, the positioning structure includes a mounting column 25 fixedly connected to the side wall of the second motor 21, the mounting column 25 is elastically and telescopically connected to the extrusion column 27, and one end of the extrusion column 27 extends out of the mounting column 25 and is fixedly installed with an extrusion head 28;

[0063] During the downward movement of the second motor 21, the extrusion column 27 is driven by the mounting column 25 to follow the downward movement, so that the extrusion head 28 contacts and extrude the feeding tray 2;

[0064] A slide groove is provided inside the mounting column 25, one end of the extrusion column 27 is slidably connected inside the extrusion head 28, and a spring 26 is provided inside the slide groove, and both ends of the spring 26 are respectively in contact with the extrusion column 27 and the top of the slide groove.

[0065] During the descent of the second motor 21, the extrusion head 28 will descend synchronously and contact the feed tray 2 in advance. As it continues to descend, the extrusion head 28 will drive the extrusion column 27 to slide in the slide groove inside the mounting column 25, while resisting the spring 26, thereby fixing the feed tray 2.

[0066] By fixing the feed tray 2, polishing can be performed stably, avoiding the feed tray 2 from rotating during the polishing process, and improving the processing accuracy.

[0067] The above embodiments are exemplary rather than restrictive, so without departing from the spirit or basic features of the present invention, the technical solutions of the present invention that can be implemented in other specific forms are all included in the present invention.
