Description

Technical Field

[0001] This utility model relates to the field of cosmetic sealing technology, specifically a screw capping device for cosmetic production. Background Technology

[0002] Cosmetic bottles are typically sealed with threaded caps. The tightening of the cosmetic bottle and cap is usually done by a capping device. However, ordinary capping devices cannot secure the bottle body during the capping process; they merely place the bottle body into the slot. This can cause the bottle body to rotate with the cap during the capping process, affecting the tightness of the connection between the cosmetic bottle and the cap, resulting in a loose connection between the cap and the bottle body.

[0003] Utility model CN217479022U discloses a capping device for cosmetic production, including a base, a support frame fixedly connected to one side of the base, a first cylinder fixedly mounted on one side of the support frame, a movable platform fixedly connected to the output end of the first cylinder, and a connecting rod fixedly connected to one side of the movable platform. The advantages of this utility model are: through the coordinated arrangement of the first cylinder, movable platform, connecting rod, pressure block, push block, push rod, mounting plate, telescopic rod, positioning spring, positioning plate, and protective pad, compared to ordinary capping devices, an additional structure for fixing the cosmetic bottle is added. This avoids the phenomenon that the bottle will rotate with the cap during the capping process, thereby ensuring the tightness between the cosmetic bottle and the cap, making the connection between the cap and the bottle body more secure, and thus preventing cosmetic spillage due to a loose connection between the cap and the bottle body.

[0004] However, the above-mentioned existing technology still has shortcomings in use: 1. The second cylinder that drives the clamping plate to perform clamping action is set on the rotating frame. When the cap is screwed on, the rotating frame needs to rotate, and when the rotating frame rotates, it needs to drive the second cylinder to revolve. Moreover, the number of turns of the cosmetic bottle cap is usually at least one turn. This has the defect that the wiring of the connected circuit (air pipe, wire) is more difficult due to the back and forth movement of the second cylinder; 2. The bottom of the movable stage is connected to the pressure block through the connecting rod. The pressure block has a right-angled triangular structure. When it moves downward, it can use the inclined plane to push the push rod on the platform to move, so that the positioning plate can clamp the bottle on the platform. Since the pressure block is fixedly connected to the movable stage through the connecting rod, the clamping force of the positioning plate on the bottle cannot be adjusted, which easily leads to unreliable clamping problems.

[0005] Therefore, this utility model provides a capping device for cosmetic production. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a capping device for cosmetic production to solve the problems mentioned in the background art. This utility model has the advantages of reducing the difficulty of wiring the components required to drive the bottle cap clamping and rotation, and also has the advantages of easy adjustment of the clamping force on the bottle body.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a capping device for cosmetic production, comprising a gantry frame, a cylinder 1 disposed at the top of the gantry frame, a capping motor fixedly connected to the bottom of the push-pull shaft of the cylinder 1, a cap sleeve fixedly attached to the bottom of the rotating shaft of the capping motor, three circumferentially distributed pressure rods extending through the outer peripheral wall of the cap sleeve, the pressure rods and the cap sleeve being elastically slidingly engaged, a drive sleeve capable of vertical movement being fitted around the outside of the cap sleeve, one end of each pressure rod abutting against the inner peripheral wall of the drive sleeve, the inner peripheral wall of the drive sleeve being conical, a horizontal plate fixedly connected to the push-pull shaft above the capping motor, a cylinder 2 fixedly disposed on the horizontal plate, the bottom of the output shaft of the cylinder 2 being in rolling engagement with the top of the drive sleeve.

[0008] Furthermore, the upper end face of the cover is fixedly connected to three axially evenly distributed guide shafts, the top of the drive sleeve is fixedly connected to a suspension plate, and the free end of the suspension plate is fixedly connected to a guide sleeve sleeved on the guide shafts.

[0009] Furthermore, a lug plate located outside the cover sleeve is welded to one side of the pressure rod, and a support spring is provided between the lug plate and the cover sleeve.

[0010] Furthermore, one end of the pressure rod is provided with a roller that contacts the inner circumferential wall of the drive sleeve.

[0011] Furthermore, a clamping plate is fixedly connected to the other end of the pressure rod, and a soft rubber pad is adhered to one side of the clamping plate.

[0012] Furthermore, there are two cylinders, which are located on both sides of the capping motor, and the output end of the cylinder is provided with a roller that abuts against the upper surface of the cap.

[0013] Furthermore, the horizontal plate is provided with two lifting shafts located on both sides of the cover sleeve. A wedge plate is fixedly connected to the bottom of the lifting shaft. A lead screw located on one side of the lifting shaft is rotatably mounted on the horizontal plate. A threaded sleeve sleeved outside the lead screw is fixedly connected to the outer peripheral wall of the lifting shaft through a connecting arm.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. In this utility model, a cap sleeve, a pressure rod, a cross plate, a second cylinder, and a drive sleeve are provided. When the drive sleeve moves downward, it can drive the pressure rod to clamp the bottle cap inside the cap sleeve. The output shaft of the second cylinder and the top of the drive sleeve are in rolling engagement. The second cylinder provides a downward driving force to the drive sleeve. Due to the rolling engagement, the second cylinder is stationary when the cap sleeve rotates. Compared with the prior art, this greatly reduces the difficulty of wiring the second cylinder (air pipe, wire, etc.).

[0016] 2. In this utility model, a lifting shaft and a lead screw located on one side of the lifting shaft are provided at the bottom of the horizontal plate. Then, a wedge block is fixedly provided at the bottom of the lifting shaft. The lead screw has the function of controlling the lifting shaft to lift and lower, and can adjust the initial position of the wedge block, thereby facilitating the adjustment of the clamping force of the positioning plate used to clamp the bottle.

[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] Please see Figures 1 to 4This utility model provides a technical solution: a capping device for cosmetic production, including a gate frame 1, a platform is provided at the bottom of the gate frame 1, and a clamp for clamping the bottle is provided above the platform. The structure of the clamp and the platform can adopt the structure in the patent documents mentioned in the background art. Since it is prior art, this application will not describe the structure of the clamp and the platform (not shown in the figure).

[0024] In this technical solution, a cylinder 2 is installed at the top inside the gantry frame 1. A capping motor 3 is fixedly connected to the bottom of the push-pull shaft 21 of the cylinder 2. The cylinder 2 provides driving force for the up-and-down movement of the capping motor 3. A cap sleeve 4 is fixed to the bottom of the rotating shaft 31 of the capping motor 3. The capping motor 3 provides driving force for the rotation of the cap sleeve 4. The cap sleeve 4 has an opening facing downwards and a blind end at the top. The space inside the cap sleeve 4 is for placing bottle caps.

[0025] Furthermore, three circumferentially distributed pressure rods 5 are provided through the outer peripheral wall of the cap sleeve 4. When the pressure rods 5 move radially in the opposite direction to the cap sleeve 4 and towards the center, they can clamp the bottle cap located inside the cap sleeve 4. The pressure rods 5 and the cap sleeve 4 are elastically slidingly engaged. The elasticity here serves to reset the pressure rods 5. Specifically, the pressure rods 5 are continuously subjected to an outward elastic thrust. In a preferred implementation, an ear plate 51 located outside the cap sleeve 4 is welded to one side of the pressure rod 5. A support spring 9 is provided between the ear plate 51 and the cap sleeve 4. The support spring 9 applies an elastic thrust to the pressure rod 5 through the ear plate 51. A drive sleeve 6 that can move up and down is fitted on the outside of the cap sleeve 4. Specifically, three axially evenly distributed guide shafts 41 are fixedly connected to the upper end face of the cap sleeve 4. A suspension plate 61 is fixedly connected to the top of the drive sleeve 6. A guide sleeve 611 fitted on the guide shafts 41 is fixedly connected to the free end of the suspension plate 61. One end of the aforementioned pressure rod 5 abuts against the inner peripheral wall of the drive sleeve 6. The inner peripheral wall of the drive sleeve 6 is conical, with the large end of the cone facing downwards. When the drive sleeve 6 moves downwards, it uses the inner conical surface to push each pressure rod 5 to move laterally, so that each pressure rod 5 can simultaneously clamp the bottle cap inside the cap sleeve 4 in the center.

[0026] A clamping plate 52 can be fixedly connected to the other end of the pressure rod 5. A soft rubber pad 521 is glued to one side of the clamping plate 52. When the bottle cap is clamped, the soft rubber pad 521 abuts against the outer peripheral wall of the bottle cap. The soft rubber pad 521 can prevent the bottle cap from being pinched and can also increase the friction between the clamping plate 52 and the bottle cap.

[0027] A horizontal plate 7 located above the capping motor 3 is fixedly connected to the push-pull shaft 21. A cylinder 8 is fixedly mounted on the horizontal plate 7. The bottom of the output shaft of the cylinder 8 rolls into contact with the top of the drive sleeve 6. The function of the cylinder 8 is to provide downward driving force to the drive sleeve 6. Specifically, the output end of the cylinder 8 is equipped with a roller 81 that abuts against the upper surface of the cap sleeve 4. Since the cap sleeve 4 rotates, it will drive the drive sleeve 6 to rotate synchronously. The roller 81 allows the cylinder 8 to push the drive sleeve 6 downward in place. Preferably, there are two cylinders 8, located on both sides of the capping motor 3. The arrangement of two cylinders 8 ensures that the drive sleeve 6 is subjected to force evenly. In order to improve the support strength of the horizontal plate 7, telescopic guide rods can be installed between the two ends of the horizontal plate 7 and the top inside the gantry frame 1.

[0028] In this embodiment, one end of the pressure rod 5 is provided with a roller 53 that contacts the inner peripheral wall of the drive sleeve 6. This arrangement greatly reduces the friction between the pressure rod 5 and the inner peripheral wall of the drive sleeve 6. Thus, when the cylinder 8 returns, the pressure rod 5 will elastically reset and push the drive sleeve 6 upward through the roller 53 in conjunction with the conical surface inside the drive sleeve 6. At this time, the pressure rod 5 no longer clamps the bottle cap and has the function of automatic reset of the pressure rod 5.

[0029] In this embodiment, two lifting shafts 101 are respectively located on both sides of the cap sleeve 4 on the horizontal plate 7. In specific implementation, a positioning sleeve can be welded to the bottom of the horizontal plate 7 and fitted onto the outside of the lifting shafts 101. The lifting shafts 101 can move up and down along the positioning sleeve. A wedge plate 102 is fixedly connected to the bottom of the lifting shafts 101. When the lifting shafts 101 move up and down, the distance between the wedge plate 102 and the horizontal plate 7 can be changed, thereby changing the initial position of the wedge plate 102. When the horizontal plate 7 descends, the wedge plate 102 will descend and use its own inclined surface to push the push block at one end of the push rod on the platform to move laterally. When the initial position of the wedge plate 102 changes, the position of the push block changes accordingly, thereby adjusting the clamping force of the positioning plate on the bottle. This makes the clamping force of the positioning plate on the bottle adjustable, and this device can make the bottle be in the optimal clamping and anti-rotation state during the capping process. It should be noted that this setting can reduce the difficulty of clamping bottles with different outer diameter specifications.

[0030] Furthermore, a lead screw 103 located on one side of the lifting shaft 101 rotates on the horizontal plate 7. Specifically, the lead screw 103 is set to pass through the horizontal plate 7 vertically. A positioning sleeve that is rotatably connected to the lead screw 103 can be welded to the lower end face of the horizontal plate 7. A threaded sleeve 1012 sleeved on the outside of the lead screw 103 is fixedly connected to the outer peripheral wall of the lifting shaft 101 through the connecting arm 1011. When the lead screw 103 rotates, it can use the rotational force to push the lifting shaft 101 to move axially. In specific implementation, a knob can be welded to the upper end face of the lead screw 103 for convenient manual turning operation.

[0031] Working principle: When it is necessary to screw caps onto the bottle, first place the bottle on the platform, then put the cap on the bottle opening, then control the push stroke of cylinder 2, the push-pull shaft 21 descends, and the cap sleeve 4 is put on the outside of the cap. Then start cylinder 8, the output shaft of cylinder 8 pushes the drive sleeve 6 downward. The drive sleeve 6 uses its inner conical surface to cooperate with roller 53 to push the pressure rod 5 towards the center of the cap sleeve 4, and the support spring 9 is compressed. At this time, the clamping plate 52 uses the soft rubber pad 521 to clamp the cap. Then start the capping motor 3, and at the same time control the push-pull shaft 21 of cylinder 2 to feed, the cap sleeve 4 rotates, and the cap is screwed onto the bottle, completing the capping process.

[0032] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
