[0040] Embodiment 3

[0041] The main difference between the disc paper grabbing device of the present embodiment and that of Embodiment 2 is that, as shown in Figure 2 , Figure 3 and Figure 4 , in order to guide the second pulley set, and ensure that the second pulley set can be effectively guided during lifting, the first housing 35 is further provided with a first connecting arm 7.

[0048] That is, when the second pulley set moves up or down as a whole, since one end of the second synchronous belt 23 is fixed, the fixed end of the second synchronous belt 23 does not move down with the second pulley set as a whole, but is folded and turned over from the fixed end by the pulling and pushing action of the third and fourth pulleys 15 and 16.

[0052] Embodiment 6

[0053] The embodiment provides a disc paper grabbing device, and the main difference from the embodiment 5 is that in the embodiment, specifically, the driving mechanism comprises a servo motor 4, a speed reducer 5, a driving gear 6 and a driven gear 12. The first pulley 11 is coaxially arranged with the driven gear 12, the servo motor 4 drives the driving gear 6 to rotate through the speed reducer 5, and then drives the driven gear 12 to rotate, and then drives the first pulley 11 to rotate.

[0054] Embodiment 7

[0055] The embodiment provides a disc paper grabbing device, and the main difference from the embodiment 5 is that in the embodiment, specifically, the driving mechanism comprises a servo motor 4, a speed reducer 5, a driving gear 6 and a driven gear 12. The first pulley 11 is coaxially arranged with the driven gear 12, the servo motor 4 drives the driving gear 6 to rotate through the speed reducer 5, and then drives the driven gear 12 to rotate, and then drives the first pulley 11 to rotate. Figure 5 And Figure 6 As shown in the drawings, in order to facilitate the tightening of the inner circle of the disc paper by the tightening method, and facilitate grabbing, the grabbing mechanism comprises a mounting plate 28 connected to the lower end of the secondary telescopic profile 19. The mounting plate 28 is provided with an air claw 25, and the air claw 25 is connected with a supporting block 27 for tightening the inner circle of the disc paper.

[0056] That is, by opening the three air claws, the three supporting blocks 27 are driven to tighten on the inner circle of the disc paper, and the grabbing action of the disc paper is completed.

[0057] Embodiment 8

[0058] The embodiment provides a disc paper grabbing device, and the main difference from the embodiment 7 is that in the embodiment, in order to turn over during the grabbing process, the air claw 25 is reversibly connected to the mounting plate 28 through an air claw turnover shaft.

[0059] The mounting plate 28 is provided with a turnover driving air cylinder 30 for driving the air claw turnover shaft to rotate, and the extension end of the turnover driving air cylinder 30 is connected with the air claw turnover shaft through a connecting block 31.

[0060] That is, if the disc paper needs to be turned over and placed during the grabbing and transporting process and after being transported to the position, the air claw turnover shaft can be driven to rotate by the turnover driving air cylinder, and then the disc paper sleeved on the air claw changes state.

[0061] Embodiment 9

[0062] The main difference between the disc paper grabbing device and the embodiment 8 is that, in the embodiment, the outer side cover of the air claw 25 is provided with a connecting shell 24, so as to facilitate the disc paper to be unloaded from the air claw.

[0063] Specifically, the disc paper grabbing device provided by the utility model has the following working steps:

[0064] In the lifting mechanism, the servo motor 7 drives the driving gear 6 to work through the speed reducer 5, and after the driving gear 6 works, the first synchronous belt 22 starts to rotate. Since the upper end of the first synchronous belt 22 is fixed to the first connecting plate 20, and the first connecting plate 20 is fixed to the first sliding block 14 and the second connecting plate 21 respectively, the second connecting plate 21 is connected with the second housing 34, the second connecting arm 8, the third belt pulley 15 and the fourth belt pulley 16.

[0065] Therefore, when the first synchronous belt 22 starts to rotate, the second connecting arm 8, the third belt pulley 15, the fourth belt pulley 16 and the first sliding block 14 will be driven to move downward along the fixed first guide rail 9 as a whole through the second connecting plate 21 and the second housing 34.

[0066] At the same time, since the lower end of the second synchronous belt 23 is connected with the second sliding block 17, the outer side of the second sliding block 17 is fixedly connected with the first housing 35, and the inner side of the second sliding block 17 is slidably connected with the second guide rail on the second connecting arm 8.

[0067] Therefore, when the second connecting arm 8 moves downward as a whole, the second synchronous belt 23 will be pushed to rotate and spread downward through the third belt pulley 15 and the fourth belt pulley 16.

[0068] Since the upper end of the outer side of the second synchronous belt 23 is fixed with the third sliding block 33 and the third connecting plate 18, and the third connecting plate 18 is connected with the secondary telescopic profile 19, when the second synchronous belt 23 rotates, the secondary telescopic profile 19 will move downward along the third guide rail 32 through the third connecting plate 18 and the third sliding block 33.

[0069] Since the grabbing mechanism is fixed to the bottom end of the secondary telescopic profile 19, finally, one motor rotation drives two synchronous belts to rotate, and then drives the grabbing mechanism to quickly move downward, which reduces the occupied space of the disc paper grabbing device, improves the flexibility and positioning accuracy of the device, and improves the telescopic speed and telescopic efficiency of the device.

[0070] The specific action of the grabbing mechanism is that the turnover driving cylinder 30 can push the connecting block 31 to rotate, the connecting block 31 and the shaft are connected through a key, and then the claw turnover shaft is driven to rotate, so that the rear grabbing mechanism 2 is turned over.

[0071] The support block 27 on the grabbing mechanism 2 is fixed on the claw 25, the claw 25 can be expanded, and then the support block 27 supports the inner circle of the disc paper, so that the disc paper is clamped. After reaching the next work position, the guide rod cylinder 26 can push the disc paper to the specified work station through the push plate 29.

[0072] Finally, it should be noted that: the above examples are used to illustrate the technical solutions of the present application, but not to limit it; although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that: the specific implementation of the present application can still be modified or some technical features can be replaced by equivalent; without departing from the spirit of the technical scheme of the present application, it should be covered in the technical scheme range of the present application claimed by the present application.
