[0019] The following will combine the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0020] Example:

[0021] This embodiment provides a bottle cap mold blank grinding device, which can play a good auxiliary fixing role when grinding the mold blank, while increasing the grinding uniformity and improving the grinding accuracy of the grinding device.

[0022] See also Figure 1-Figure 3 , the utility model provides a technical solution:

[0023] A bottle cap mold blank grinding device includes a support frame 1, a grinding table 2 is installed above the support frame 1, the bottom of the grinding table 2 is fixedly connected to the support frame 1 through multiple groups of support rods 3, the top of the grinding table 2 is rotatably connected to a rotating table 4, the top of the rotating table 4 is installed with a fixed seat 5, the inner side of the fixed seat 5 is provided with a fixing groove 6, the inside of the fixing groove 6 is slidably connected with a clamping block 7, the left side of the clamping block 7 is threadedly connected to the fixed seat 5 through a first threaded rod 8, a driving mechanism 9 is installed on the top of the support frame 1 and below the grinding table 2, and a grinding frame 10 is installed at the top end of the inner side of the support frame 1.

[0024] First, the front and rear sides of the turntable 4 are fixedly connected with a slide 11, and an annular slide groove 12 is provided at the top of the grinding table 2 and at the bottom of the slide 11. The bottom of the slide 11 is slidably connected to the annular slide groove 12 through a slider. When the turntable 4 rotates, the slider at the bottom of the slide 11 slides in cooperation with the inside of the annular slide groove 12, thereby improving the rotation stability of the turntable 4 and ensuring the grinding accuracy of the mold blank.

[0025] Furthermore, a protective pad 13 is installed on the right side of the clamping block 7 and the right side inside the fixing groove 6. The protective pad 13 is made of hard rubber material, and the outer side of the protective pad 13 is provided with anti-slip grooves. The first threaded rod 8 is connected to the clamping block 7 by a rotational connection. An operating handle 14 is installed on the end of the first threaded rod 8 away from the clamping block 7. The position of the mold blank to be polished is placed upward into the fixing groove 6 inside the fixing seat 5, and then the first threaded rod 8 is rotated by the operating handle 14, so that the clamping block 7 slides in the fixing groove 6 and cooperates with the fixing seat 5 to clamp and fix the mold blank. At the same time, when the mold blank is clamped and fixed, the outer side of the mold blank can be protected by the protective pad 13 to prevent damage to the outer side of the mold blank, and at the same time, the fixing effect of the mold blank can be improved.

[0026] In this embodiment, the specific structure of the driving mechanism 9 is as follows:

[0027] The driving mechanism 9 includes a driving box 15, a rotating rod 16, a first bevel gear 17, a first motor 18, a driving rod 19 and a second bevel gear 20. The driving box 15 is located at the top of the support frame 1, the rotating rod 16 is fixedly connected to the center of the bottom of the rotating table 4, the first bevel gear 17 is fixedly connected to the bottom end of the rotating rod 16, the first motor 18 is located at the top of the support frame 1 and on the back of the driving box 15, the driving end of the first motor 18 is rotatably connected to the driving box 15 through the driving rod 19, and the driving rod 19 is meshed with the first bevel gear 17 through the second bevel gear 20.

[0028] Furthermore, after the mold blank is clamped and fixed, the driving rod 19 is driven to rotate by the first motor 18, and under the transmission action of the second bevel gear 20 and the first bevel gear 17, the rotating rod 16 is driven to rotate, thereby driving the rotating table 4 to rotate, and with the cooperation of the grinding frame 10, the surface of the mold blank can be fully polished.

[0029] Secondly, the internal rotation of the grinding frame 10 is connected to the second threaded rod 21, and the second threaded rod 21 is located at the top of the grinding frame 10 and is equipped with a second motor 22. The outer side of the second threaded rod 21 is threadedly connected to the adjusting seat 23, and the front of the adjusting seat 23 is equipped with a telescopic cylinder 24. The driving end of the telescopic cylinder 24 is equipped with a mounting plate, and the inner side of the mounting plate is vertically equipped with an electric grinder 25. After the mold blank is fixed, the second threaded rod 21 is driven to rotate by the second motor 22, so that the adjusting seat 23 is driven to descend by the rotation of the second threaded rod 21, and then the electric grinder 25 is lowered to grind and polish the surface of the mold blank. At the same time, with the cooperation of the telescopic cylinder 24 and the rotating table 4, as the telescopic cylinder 24 is extended and retracted and the rotating table 4 rotates, the electric grinder 25 performs a circular motion from the outside to the inside or from the inside to the outside to uniformly grind the surface of the mold blank, thereby greatly improving the grinding accuracy of the mold blank.

[0030] Finally, a scale plate 26 is installed on the right side of the grinding frame 10, and a pointer is fixedly connected to the position on the right side of the adjustment seat 23 corresponding to the scale plate 26. When the electric grinder 25 grinds the surface of the mold blank, the height to which the adjustment seat 23 is lowered can be observed through the scale plate 26, thereby controlling the grinding thickness and further improving the grinding accuracy of the mold blank.

[0031] In this embodiment, the implementation scenario is specifically as follows: when grinding the surface of the mold blank, the position of the mold blank to be ground is placed upward into the fixing groove 6 inside the fixing seat 5, and then the first threaded rod 8 is rotated to cooperate with the fixing seat 5 to clamp and fix the mold blank, and then the second motor 22 on the grinding frame 10 is started, so that the adjustment seat 23 is driven to descend by the rotation of the second threaded rod 21, and then the electric grinder 25 is lowered to grind and polish the surface of the mold blank, and at the same time, the driving rod 19 is driven to rotate by the first motor 18, and the second bevel gear 20 and the first bevel gear are connected. Under the transmission action of the gear 17, the rotating rod 16 is driven to rotate, thereby driving the rotating table 4 to rotate. With the cooperation of the telescopic cylinder 24 on the grinding frame 10, the electric grinder 25 can comprehensively grind the surface of the mold blank. As the telescopic cylinder 24 is extended and retracted and the rotating table 4 rotates, the electric grinder 25 performs a circular motion from the outside to the inside or from the inside to the outside to uniformly grind the surface of the mold blank. The entire operation process is simple and convenient. Compared with the existing mold blank grinding method, the utility model can improve the overall grinding uniformity and grinding accuracy of the mold blank grinding device through design.

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
