Description

Technical Field

[0001] This utility model belongs to the field of bottle sealing technology, specifically relating to a rotary capping machine. Background Technology

[0002] In packaging production lines of industries such as food, pharmaceuticals, and daily chemicals, capping machines are key equipment for achieving automated sealing connections between bottles and caps. Their capping efficiency and sealing reliability directly affect the packaging quality and production pace of products.

[0003] Currently, traditional capping devices mostly use single-wheel pressing or step-by-step rotation to complete the capping action. Their transmission structure is complex, and the synchronization of multiple drive components is poor. This can easily lead to inconsistent speeds of the pressing rollers, resulting in uneven force on the bottle cap and further reducing the stability of the capping quality.

[0004] Therefore, a rotary cap-locking machine was designed to overcome the aforementioned technical shortcomings. Utility Model Content

[0022] This specific embodiment is a rotary cap-locking machine, and its structural schematic diagram is shown below. Figures 1-4As shown, the system includes a conveyor platform 1. Two limiting platforms 2 are mounted on the top surface of the conveyor platform 1. A transmission component 3, comprising a servo motor and a conveyor belt, is installed on the top surface of each limiting platform 2. The conveyor belt is distributed on the opposite sidewall of each limiting platform 2. The area between the two limiting platforms 2 is the bottle conveying area. The conveyor belt can be used for auxiliary bottle conveying, and the use of the transmission component 3 can be selected according to actual needs. Two clamping assemblies are provided on the top surface of each limiting platform 2. A bracket 4 is fixedly connected to the rear sidewall of the conveyor platform 1. A control box 5 is fixedly connected to the sidewall of the bracket 4. Four limiting slots are symmetrically opened on the bottom of the control box 5. A drive shaft 8 is rotatably connected within each limiting slot. A pressure roller 9 is mounted at the bottom end of the drive shaft 8, and a drive assembly is provided on the sidewall of the drive shaft 8.

[0023] Among them, the pressure roller 9 is preferably made of rubber, and the surface of the pressure roller 9 is provided with anti-slip texture, which can increase the friction between it and the bottle cap, so as to drive the bottle cap to lock quickly and prevent slippage. In addition, the height of the pressure roller 9 is greater than the height of the bottle cap. During the capping process, the bottle cap can move down between the pressure rollers 9, thereby ensuring the contact surface between the bottle cap and the pressure roller 9 and improving its stability.

[0024] like Figure 1 As shown, the clamping assembly includes a first cylinder 6 fixedly installed on the top surface of the limiting platform 2. An arc-shaped plate 7 is fixedly connected to the telescopic end of the first cylinder 6. The arc surfaces of the two arc-shaped plates 7 face each other, and the two arc-shaped plates 7 are located below the pressure roller 9. The structure used in the clamping assembly is a mature existing technology and will not be described in detail in this solution.

[0025] like Figure 3 As shown, the drive assembly includes a motor 10 fixedly installed on the top surface of the control box 5. A first gear 13 is fixedly connected to the output end of the motor 10. Two support plates 11 are provided on the inner wall of the control box 5. The top end of the drive shaft 8 passes through the support plate 11 and is fixedly connected to a second gear 12. The drive shaft 8 is rotatably connected to the support plate 11. A clamping assembly is provided on the side wall of the support plate 11.

[0026] Specifically, in the initial state of the pressure roller 9, the second gear 12 and the first gear 13 are not meshed. When the pressure roller 9 is pressed against the bottle cap, the second gear 12 moves with the transmission shaft 8 and can mesh with the first gear 13 to achieve synchronous transmission. Furthermore, the diameter of the first gear 13 is larger than the diameter of the second gear 12, which can realize synchronous transmission of the four second gears 12.

[0027] like Figure 4As shown, the clamping assembly includes a horizontal plate 14 fixedly connected to the inner wall of the control box 5, racks 15 fixedly connected to the side walls of the support plate 11, a third gear 16 rotatably connected to the top surface of the horizontal plate 14 between the two racks 15, the racks 15 on both sides meshing with the third gear 16, a second cylinder 17 fixedly installed on the top surface of the horizontal plate 14, and the telescopic end of the second cylinder 17 fixedly connected to the end face of one of the racks 15.

[0028] The second cylinder 17 is used as the drive, and the third gear 16 and rack 15 work together to make the two side support plates 11 move relative to each other, thereby driving the two side pressure rollers 9 to move synchronously. When the pressure rollers 9 contact the bottle cap, their contact force is consistent.

[0029] like Figure 3 and Figure 4 As shown, two sliding grooves 19 are provided on the top surface of the horizontal plate 14, and the support plate 11 is L-shaped, with one end face of the support plate 11 slidably connected to the sliding groove 19. The sliding groove 19 can limit the position of the support plate 11, and the other side wall of the support plate 11 can be slidably connected to the inner wall of the control box 5.

[0030] like Figure 4 As shown, a mounting plate 18 is fixedly connected to the side wall of the horizontal plate 14, and the mounting plate 18 is fixedly connected to the inner wall of the control box 5. The mounting plate 18 is only one fixing or supporting method in this scheme. In actual assembly, other installation methods can be used to replace it.

[0031] Working principle: First, bottles are sequentially fed onto the conveyor table 1 via external equipment. The bottles move between the conveyor table 1 and the limiting table 2. During this movement, an external cap-placement mechanism places the caps on the bottles. When the bottles move between the two curved plates 7, the first cylinder 6 is activated. The telescopic end of the first cylinder 6 drives the curved plates 7 to clamp the bottles, simultaneously using the curved surface of the curved plates 7 to center the bottles. Then, the second cylinder 17 is activated. The telescopic end of the second cylinder 17 drives one of the racks 15 to move. The rack 15 meshes with the third gear 16 to drive... On the other side, rack 15 moves in the opposite direction. Both racks 15 drive the two transmission shafts 8 to move toward the bottle cap via support plate 11, which is used to press the bottle cap. When pressure roller 9 is in contact with the bottle cap, the second gear 12 meshes with the first gear 13. Then the motor 10 is started. The output shaft of motor 10 drives the first gear 13 to rotate. The first gear 13 drives the four second gears 12 to rotate synchronously, and drives the pressure roller 9 to rotate via transmission shaft 8, thus tightening the bottle cap onto the bottle body. After the cap is locked, the second cylinder 17 is reset, thus completing one cap locking cycle, effectively improving the stability and efficiency of cap locking.

[0032] All technical features in this embodiment can be freely combined according to actual needs.

[0033] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
