[0002] The automatic cap tightening equipment for glass aromatherapy bottles is a specialized piece of equipment developed for the cap tightening process of glass aromatherapy bottles in the field of automated packaging equipment technology. In the production process of aromatherapy products, the cap tightening process of glass aromatherapy bottles is crucial.

[0003] Traditional operating methods have several problems. Manual tightening is inefficient and cannot meet the needs of large-scale production. Furthermore, differences in the force and technique of different workers lead to inconsistent tightening of the caps, making it difficult to guarantee product sealing. This not only affects product quality but may also cause problems such as leakage of the fragrance liquid. During the tightening process, issues such as bottle shaking and inaccurate cap positioning can easily occur, resulting in loose caps or damage to the bottle. To address these issues, an automatic cap tightening device for glass fragrance bottles has been proposed for improvement and upgrading. Utility Model Content

A tightening motor is installed on the outer side of the positioning frame, a reducer is fixedly installed at the output end of the tightening motor, and a guide rod is fixedly connected to one end of the reducer. A tightening head is fixedly installed at one end of the guide rod. Two sets of adjustment structures are provided on both sides of the anti-slip conveyor belt at the upper end of the conveyor frame.

[0006] The conveyor frame is symmetrically positioned on both sides of the tightening head. The positioning structure includes positioning seats fixedly installed at opposite positions on the upper end of the conveyor frame. Positioning cylinders are fixedly installed inside the two positioning seats. One end of each positioning cylinder is fixedly connected to a clamping positioning plate, and a flexible rubber pad is fitted to the outer wall of the clamping positioning plate. The two clamping positioning plates are adapted to the size of the aromatherapy bottle.

[0007] As a preferred embodiment of the above technical solution, the outer wall of the clamping positioning plate is symmetrically fixedly equipped with protrusions, and the outer walls of both sets of protrusions are fixedly connected with telescopic rods, with the bottom of the telescopic rods installed on the outer wall of the positioning seat.

[0008] As a preferred embodiment of the above technical solution, a support frame is fixedly provided on the upper end of the positioning frame, and a telescopic cylinder is fixedly installed inside the support frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model device is equipped with a positioning structure. Through precise positioning, clamping, and tightening control, two positioning cylinders drive two clamping positioning plates to move relative to each other to clamp and position the empty bottle. At the same time, a flexible rubber pad protects the outside of the empty bottle. Then, a drive telescopic cylinder drives a guide slider to move downward along the slide rail, which drives the tightening motor to drive the tightening head on the guide rod to tighten the bottle cap. This ensures that each bottle cap is tightened with the appropriate torque, improving the consistency of bottle cap tightening and the sealing of the product, effectively reducing the defect rate, avoiding problems such as inconsistent tightening degree caused by differences in the operating force and technique of different workers, and improving the stability and efficiency of automatic tightening of glass aromatherapy bottle caps.

[0014] 2. The device of this utility model is equipped with an adjustment structure. By rotating two sets of rotating handwheels, the limit frame on the adjustment screw is moved precisely using the scale line, which causes the two sets of internal multiple limit rollers to move relative to each other to limit the sliding of glass aromatherapy bottles of different sizes. This ensures that the position of the glass aromatherapy bottle is always relative to the position of the tightening head, thus improving the applicability of the tightening equipment.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figures 1 to 4As shown in the figure, this embodiment provides an automatic glass aromatherapy bottle cap tightening device, including a machine base 1. A conveyor frame 3 is fixedly installed on the upper surface of the machine base 1. An anti-slip conveyor belt 4 is rotatably installed inside the conveyor frame 3. A transparent protective cover 2 is fixedly installed above the conveyor frame 3. A photoelectric sensor 6 is fixedly installed on the inner wall of the transparent protective cover 2. A PLC controller 8 is fixedly installed on the outer wall of the transparent protective cover 2. A positioning frame 91 is fixedly installed inside the transparent protective cover 2. A tightening motor 95 is set on the outer side of the positioning frame 91. A reducer is fixedly installed at the output end of the tightening motor 95. A guide rod 96 is fixedly connected to one end of the reducer. A tightening head 9 is fixedly installed at one end of the guide rod 96. Two sets of adjustment structures 5 are set on both sides of the anti-slip conveyor belt 4 at the upper end of the conveyor frame 3.

[0024] A positioning structure 7 is symmetrically arranged on both sides of the tightening head 9 above the conveyor frame 3. The positioning structure 7 includes a positioning seat 71 fixedly installed at the upper end of the conveyor frame 3. A positioning cylinder 72 is fixedly installed inside each of the two positioning seats 71. A clamping positioning plate 74 is fixedly connected to one end of each of the two positioning cylinders 72, and a flexible rubber pad 75 is attached to the outer wall of the clamping positioning plate 74. The two clamping positioning plates 74 are adapted to the size of the aromatherapy bottle.

[0025] like Figures 2 to 3 As shown, protrusions 76 are symmetrically fixedly installed on the outer wall of the clamping positioning plate 74. Telescopic rods 73 are fixedly connected to the outer walls of both sets of protrusions 76, and the bottom of the telescopic rods 73 is installed on the outer wall of the positioning seat 71. A support frame is fixedly installed on the upper end of the positioning frame 91, and a telescopic cylinder 92 is fixedly installed inside the support frame. A guide slider 93 is fixedly connected to one end of the telescopic cylinder 92, and the guide slider 93 is slidably connected to the slide rail 94. The slide rail 94 is fixedly installed on the outer wall of the positioning frame 91. The tightening motor 95 is fixedly installed on the upper end of the guide slider 93, and the reducer housing is installed on the guide slider 93.

[0026] Glass aromatherapy bottles are fed onto the bottle conveyor frame 3 via an automatic feeding device. The bottles then move sequentially towards the tightening station via an anti-slip conveyor belt 4. A vibratory feeder automatically sorts and feeds the bottle caps, with an orientation mechanism at the feeder outlet to ensure the caps enter the feeding track in the correct orientation. A vacuum suction device, driven by a robotic arm, descends to pick up the caps and place them above the bottle opening. This technology is mature and widely used. A telescopic cylinder 92 drives the tightening motor 95 on the guide slider 93 to move up and down, facilitating the tightening of the caps and bottle. The tightening process is performed by setting a protrusion 76 on the rear side of the clamping positioning plate 74 and connecting it to the telescopic rod 73 within the positioning seat 71 for sliding engagement, which facilitates the relatively stable movement of the clamping positioning plate 74. The PLC controller 8 can set parameters such as tightening torque and speed through the touch screen operation panel. A photoelectric sensor 6 is set at the discharge end of the conveyor. When the empty bottle moves towards the tightening station with the anti-slip conveyor belt 4 and reaches the discharge end, it will block the light emitted by the photoelectric sensor 6. The photoelectric sensor 6 detects the bottle's arrival signal. The photoelectric sensor 6 is an IO-Link photoelectric sensor 6.

[0027] like Figure 4 As shown, the adjustment structure 5 includes two sets of limit seats 51 fixedly installed on both sides of the anti-slip conveyor belt 4. The two sets of limit seats 51 are internally threaded with adjustment screws 53. One end of the adjustment screw 53 is fixedly connected to a rotating handwheel 52. One end of the adjustment screw 53 is rotatably mounted with a limit frame 54. The limit frame 54 is rotatably mounted with a limit roller 55. The limit frame 54 is symmetrically fixedly mounted with a slide rod 56 on the rear side. The slide rod 56 is slidably connected inside the limit seat 51.

[0028] By rotating two sets of handwheels 52, the limiting brackets 54 on the adjusting screw 53 are moved, causing two sets of several limiting rollers 55 to move relative to each other to limit the movement of glass aromatherapy bottles of different sizes. The operator only needs to replace the clamping positioning plate 74, which is simple to operate.

[0029] The working principle and process of this utility model: The glass aromatherapy bottle enters the bottle conveyor frame 3 through the automatic feeding device. The glass aromatherapy bottle moves to the tightening station in sequence under the drive of the anti-slip conveyor belt 4. The vacuum suction device of the cap supply mechanism descends under the drive of the mechanical arm, picks up the cap and places it above the bottle mouth. At this time, according to the different sizes of glass aromatherapy bottles, the adjusting screws 53 on the two sets of rotating handwheels 52 are rotated inside the limiting seat 51. The adjusting screws 53 synchronously drive the multiple limiting rollers 55 in the limiting frame 54 to move relatively accurately using the scale lines on the conveyor frame 3. When the two sets of limiting rollers 55 are in contact with the outside of the glass aromatherapy bottle, they stop moving. This can adapt to the tightening of bottle caps of glass aromatherapy bottles with different diameters.

[0030] When the photoelectric sensor 6 detects that the bottle has reached the tightening station, the anti-slip conveyor belt 4 stops running. At this time, the positioning cylinders 72 in the two positioning seats 71 drive the clamping positioning plates 74 to move relative to each other to clamp the outside of the glass aromatherapy bottle. The flexible rubber pads 75 on the outer wall of the clamping positioning plates 74 fit against the glass aromatherapy bottle to protect it during clamping. Then, the telescopic cylinder 92 drives the tightening motor 95 on the guide slider 93 to move downward. When the tightening head 9 is fitted with the glass aromatherapy bottle, the reducer drives the tightening head 9 on one end of the guide rod 96 to rotate. The tightening head 9 tightens the bottle cap onto the bottle. During the tightening process, after tightening is completed, the tightening motor 95 stops rotating. The telescopic cylinder 92 moves the tightening motor 95 upward. Finally, the positioning cylinder 72 drives the clamping positioning plates 74 to release the bottle. The bottle continues to run on the anti-slip conveyor belt 4 and the glass aromatherapy bottle with the tightened bottle cap is transported to the next process.
