[0004] When the tightening device in the above patent rotates the bottle cap, the bottle cap needs to be placed in the middle of multiple clamping sleeves inside the tightening sleeve first, and the bottle cap is fixed by the second pneumatic rod. When the tightening sleeve is driven to rotate by the rotating motor, the multiple second pneumatic rods on the tightening sleeve are connected to the air circuit. In this way, the connecting pipe between the second pneumatic rod and the air circuit will become knotted or broken during rotation, so that the second pneumatic rod cannot effectively fix the bottle cap.

[0005] Therefore, we provide an automatic tightening mechanism for the top cover of a mascara. In this device, the mascara bottle is fixed by two first cylinders, and then the motor is driven downward by the second cylinder and the L-shaped frame.

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] See also Figure 1-8In an embodiment of the utility model, an automatic tightening mechanism for a mascara top cover comprises a conveyor 1; a guide plate 2 symmetrically installed is arranged on the conveyor 1; the guide plate 2 is fixedly installed with the conveyor 1 through a support rod 12; first cylinders 4 are arranged on both sides of one end of the guide plate 2; two first cylinders 4 are fixedly installed with the conveyor 1 through a mounting seat 3; a motor 10 is arranged above the middle position of the two first cylinders 4; a plurality of support arms 13 are arranged at the bottom of the motor 10; a pressure block 14 is arranged inside the plurality of support arms 13; the pressure block 14 is arranged in a stepped shape; the pressure block 14 is connected to the support arm 13 by screws;

[0032] One side of the motor 10 is fixedly mounted with the push rod of the second cylinder 15 via an L-shaped frame 16; the second cylinder 15 is fixedly mounted on one side of the slide plate 6 via an L-shaped fixing plate 17, and the slide plate 6 is also provided with a third cylinder 11;

[0033] Both ends of the slide plate 6 are slidably connected to the slide column 5 through a sliding sleeve; two slide columns 5 are provided with a support plate 7 at the top of the third cylinder 11; the support plate 7 is detachably connected to the slide column 5 through a bolt; the side of the support plate 7 away from the third cylinder 11 is movably connected to the screw rod 9 through a bearing; both ends of the third cylinder 11 are fixedly installed with the support plate 7 and the slide plate 6;

[0034] By adopting the above technical solution, when in use, the mascara bottle body is placed on the conveyor 1, and the bottle body is passed through in sequence through the two guide plates 2, and then the top cover is placed on the top of the bottle body, so as to realize effective transmission in sequence and prevent the occurrence of a messy situation;

[0035] Furthermore, after the bottle body is separated from the guide plate 2, the push rods of the two first cylinders 4 are used to fix the bottle body through the induction of the sensor 18. After the two first cylinders 4 are fixed, the second cylinder 15 installed on one side of the slide plate 6 drives the motor 10 to move through the L-shaped frame 16. When the push rod of the second cylinder 15 is retracted to the bottom, the pressing block 14 on the inner side of the support arm 13 at the bottom of the motor 10 fits with the top of the top cover, and driven by the motor 10, the pressing block 14 drives the top cover to rotate;

[0036] A top plate 8 is also fixedly mounted on the top of the slide column 5; a threaded hole is opened in the middle of the top plate 8, and a screw rod 9 is installed through it;

[0037] The bottom of the slide column 5 is fixedly mounted to the conveyor 1 via the mounting seat 3 .

[0038] By adopting the above technical solution, when tightening downward, the third cylinder 11 drives the slide plate 6 to move downward to compensate for the stroke of the second cylinder 15, so that the motor 10 can move downward while rotating, effectively ensuring the tightening of the top cover and the bottle body.

[0039] In this embodiment, a sensor 18 is provided on one side of one of the two first cylinders 4 ; the sensor 18 is fixedly mounted to the conveyor 1 via an L-shaped mounting seat 19 ; and the probe of the sensor 18 is located in the middle of the two guide plates 2 .

[0040] Specifically, a circular groove for easy clamping is provided at the end of the push rod of the first cylinder 4, and a rubber pad is arranged in the circular groove.

[0041] By adopting the above technical solution, when the sensor 18 detects the passage of a bottle body, the two first cylinders 4 are controlled to fix the position of the bottle body. A rubber pad is installed on the push rod of the first cylinder 4, which can effectively prevent the bottle body from breaking when the two push rods clamp the bottle body.

[0042] The working principle of the utility model is as follows: when in use, the bottle body containing mascara is first placed on the conveyor 1, and the bottle body is sequentially conveyed through the two guide plates 2 on the conveyor 1. During the conveying process, the top cover is placed on the top of the bottle body, so that the bottle body and the top cover reach the sensing position of the sensor 18 at the same time. When the bottle body is separated from the guide plate 2, the sensor 18 senses the bottle body, and the push rods of the two first cylinders 4 are used by the controller to clamp and fix the bottle body.

[0043] After clamping and fixing, the second cylinder 15 on one side of the slide plate 6 drives the L-shaped frame 16 to realize the up and down movement of the motor 10. During the downward movement of the motor 10, the pressing block 14 on the inner side of the support arm 13 at the bottom of the motor 10 fits with the top cover. After fitting, the motor 10 drives the support arm 13 and the pressing block 14 to rotate.

[0044] At this time, the third cylinder 11 drives the slide plate 6 to move downward along the slide column 5, so that the movement of the slide plate 6 can achieve compensation for the stroke of the second cylinder 15, effectively achieving that the motor 10 drives the support arm 13 and the pressing block 14 to rotate and move downward at the same time, effectively ensuring that the pressing block 14 screws the top cover tightly on the top of the bottle body;

[0045] After the tightening is completed, the slide plate 6 is first moved upward by the third cylinder 11 to separate the pressing block 14 from the top cover, and then the L-shaped frame 16 is driven upward by the second cylinder 15 to reset the motor 10;

[0046] Since the pressing block 14 is arranged in a stepped shape, the pressing block 14 can effectively fit the top covers of different diameters when tightening.

[0047] When the top covers of different heights are tightened, the distance between the slide plate 6 and the conveyor 1 is adjusted by rotating the bolts through the hand wheel.
