Description

Technical Field

[0001] The utility model relates to the technical field of capping mechanisms, in particular to a capping mechanism for filling and capping. Background Art

[0002] In the liquid filling and packaging process, it is necessary to use a capping device to perform capping and sealing processing on the filled plastic bottles.

[0003] However, the capping devices in the prior art have single functions and low integration. Before capping, workers need to first put the bottle caps on the bottle mouths. Obviously, this will not only increase the labor intensity of the workers, but also easily cause the liquid materials in the bottles to be contaminated. More importantly, there is a lack of a structure for limiting the position of the plastic bottles, and the bottle body is prone to tipping during capping processing, making it inconvenient to use. Summary of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a capping mechanism for filling and capping, which solves the technical problems of low integration of the capping devices in the prior art, lack of a bottle body limiting structure, and inconvenient use, and has the advantages of being able to automatically fix the position of the plastic container during the capping process and high integration.

[0005] To solve the above technical problems, the utility model provides the following technical solutions: A capping mechanism for filling and capping includes a base body. A leveling component is movably installed at the lower end of the base body. A quantitative filling device is detachably installed at the upper end of the base body. A plastic container is placed below the quantitative filling device. A container conveying mechanism is arranged on the base body, and an automatic capping mechanism is arranged above the container conveying mechanism. After the worker places the plastic container on the container conveying mechanism, first, the quantitative filling device will perform quantitative filling on the container. Next, the automatic capping mechanism will perform capping and sealing on the container. The automatic capping mechanism includes a first support fixedly installed on the base body. A feeding convex block is fixedly installed on the first support. A vertical circular tube is coaxially arranged at the upper end of the feeding convex block. A feeding channel is opened on the feeding convex block, and the feeding channel is coaxially arranged with the vertical circular tube. A limiting component capable of enabling the bottle caps to fall in sequence is arranged on the inner side wall of the feeding channel. A positioning sensor for sensing the position of the container is arranged inside the first support. A second support is fixedly installed on one side of the first support. A driving box body is fixedly installed on the second support. A capping component is arranged at the lower end of the driving box body. When the plastic container moves below the feeding convex block, the bottle caps will fall above the container under the action of the limiting component, thereby completing the cap placing operation. Subsequently, the capping component will tighten the bottle caps.

[0006] Preferably, telescopic clamping plates for fixing the container are symmetrically installed on the second support. When the plastic container moves below the driving box body, the telescopic clamping plates will clamp and fix the plastic container.

[0007] Preferably, the limiting component is composed of two groups of limiting pieces that alternately protrude from each other. Initially, the lower group of limiting pieces is in the protruding state, thus preventing the bottle cap from falling. When the lower limiting pieces start to contract, the upper group of limiting pieces will simultaneously protrude outward. When the lower limiting pieces are completely contracted, the bottle cap located between the two groups of limiting pieces will fall downward, thereby ensuring that only one bottle cap falls each time.

[0008] Preferably, the cap screwing assembly includes a telescopic rod. A cap screwing sleeve is coaxially and fixedly installed at the lower end of the telescopic rod. A rubber ring is fixedly installed inside the cap screwing sleeve. When the telescopic rod extends downward, the cap screwing sleeve will be sleeved outside the bottle cap. Next, as the cap screwing sleeve rotates, the bottle cap will be screwed tightly.

[0009] Preferably, a driving motor is fixedly installed inside the driving box body. The output end of the driving motor is in transmission connection with the telescopic rod. When the driving motor is energized and operates, the telescopic rod will rotate rapidly.

[0010] Preferably, the container conveying mechanism includes a left mounting plate and a right mounting plate symmetrically arranged at the upper end of the seat body. Conveying rollers are respectively installed on the left mounting plate and the right mounting plate. A conveyor belt is arranged between the two conveying rollers. When the conveyor belt moves under the action of the conveying rollers, it will perform horizontal feeding on the plastic container.

[0011] By means of the above technical solution, the present utility model provides a cap screwing mechanism for filling and screwing caps, which at least has the following beneficial effects:

[0012] 1. By setting an automatic cap screwing mechanism and using the mutual cooperation between the limiting component and the cap screwing component, the present utility model can simultaneously complete the processes of placing the cap and screwing the cap, with high integration and convenient use. It can effectively improve the efficiency of cap screwing and encapsulation processing. Moreover, when screwing the cap, the telescopic clamping plate will automatically fix the position of the plastic container, which can effectively prevent the container from tipping during the cap screwing process.

[0013] 2. By setting a container conveying mechanism and using the mutual cooperation between the conveying rollers and the conveyor belt, the present utility model can automatically convey the plastic container, eliminating the need for manual feeding by workers. This can not only improve the processing efficiency but also ensure the accuracy during the filling and cap screwing operations. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0021] Embodiment 1

[0022] The capping equipment in the prior art has a single function and low integration. Before capping, the staff needs to first put the bottle cap on the bottle mouth. Obviously, this will not only increase the labor intensity of the staff, but also easily cause the liquid material in the bottle to be contaminated. More importantly, there is a lack of a structure for limiting the plastic bottle, and the bottle body is prone to tipping during the capping process, making it inconvenient to use. To solve this technical defect in the prior art, this embodiment proposes a capping mechanism for filling and capping, which can complete the processes of placing the cap and capping simultaneously, with high integration and convenient use, and can effectively improve the efficiency of capping and packaging. The lower end of the seat body 1 of the capping mechanism is movably installed with a leveling component 2, the upper end of the seat body 1 is detachably installed with a metering filling equipment 3, a plastic container 6 is placed below the metering filling equipment 3, a container conveying mechanism 4 is arranged on the seat body 1, and an automatic capping mechanism 5 is arranged above the container conveying mechanism 4. After the staff places the plastic container 6 on the container conveying mechanism 4, first, the metering filling equipment 3 will quantitatively fill the container, and then, the automatic capping mechanism 5 will cap and package the container.

[0023] In order to be able to perform both lid placing and lid screwing operations simultaneously and improve processing efficiency, an automatic lid screwing mechanism 5 is provided in this embodiment. Specifically, the automatic lid screwing mechanism 5 includes a first bracket 501 fixedly installed on the seat body 1. A feeding projection 502 is fixedly installed on the first bracket 501. A vertical circular tube 503 is coaxially arranged at the upper end of the feeding projection 502. A feeding channel is formed on the feeding projection 502, and the feeding channel is coaxially arranged with the vertical circular tube 503. A limiting component 504 capable of enabling the bottle caps to fall successively is provided on the inner side wall of the feeding channel. The limiting component 504 is composed of two groups of limiting pieces that alternately extend out. Initially, the lower group of limiting pieces is in the extended state, thus preventing the bottle caps from falling. When the lower limiting pieces start to contract, the upper group of limiting pieces will synchronously extend outwards. When the lower limiting pieces are completely contracted, the bottle caps located between the two groups of limiting pieces will fall downwards, thereby ensuring that only one bottle cap falls each time. A positioning sensor 505 for sensing the position of the container is provided inside the first bracket 501. A second bracket 506 is fixedly installed on one side of the first bracket 501. A driving box body 507 is fixedly installed on the second bracket 506. A lid screwing assembly 508 is arranged at the lower end of the driving box body 507. The lid screwing assembly 508 includes a telescopic rod. A lid screwing sleeve is coaxially and fixedly installed at the lower end of the telescopic rod. Rubber is fixedly installed inside the lid screwing sleeve. When the plastic container 6 moves to the lower part of the feeding projection 502, the bottle caps will fall above the container under the action of the limiting component 504, thereby completing the lid placing operation. Subsequently, the telescopic rod will extend downwards, so that the lid screwing sleeve is sleeved outside the bottle caps. Next, as the lid screwing sleeve rotates, the bottle caps will be screwed tightly. Telescopic clamping plates 509 for fixing the container are symmetrically installed on the second bracket 506. When the plastic container 6 moves to the lower part of the driving box body 507, the telescopic clamping plates 509 will clamp and fix the plastic container 6. A driving motor is fixedly installed inside the driving box body 507, and the output end of the driving motor is in transmission connection with the telescopic rod. When the driving motor is energized and operates, the telescopic rod will rotate rapidly.

[0024] In order to achieve automatic feeding, a container conveying mechanism 4 is provided in this embodiment. Specifically, the container conveying mechanism 4 includes a left mounting plate 401 and a right mounting plate 402 symmetrically arranged at the upper end of the seat body 1. Conveying rollers 403 are respectively installed on the left mounting plate 401 and the right mounting plate 402. A conveyor belt 404 is arranged between the two conveying rollers 403. When the conveyor belt 404 moves under the action of the conveying rollers 403, it will perform horizontal feeding on the plastic container 6.

[0025] As Figure 1 shown, during processing, the staff will successively place the plastic containers 6 above the conveyor belt 404. Next, the conveyor belt 404 will first convey the plastic containers 6 to the lower part of the quantitative filling device 3. Subsequently, the quantitative filling device 3 will add a certain amount of liquid material into the plastic containers 6.

[0026] Subsequently, the plastic container 6 filled with liquid material will move under the action of the conveyor belt 404 to the lower part of the discharging bump 502. At this time, the lower set of limiting pieces will automatically contract, causing a bottle cap to fall onto the plastic container 6, thus completing the cap placing operation.

[0027] Next, the plastic container 6 with a bottle cap will move under the action of the conveyor belt 404 to the lower part of the driving box body 507. Subsequently, the two telescopic clamping plates 509 will approach each other, thereby fixing and limiting the plastic container 6.

[0028] Next, the cap screwing sleeve will be sleeved outside the bottle cap under the action of the telescopic rod. Subsequently, the cap screwing sleeve will rotate synchronously with the telescopic rod, thereby screwing the bottle cap tightly and completing the cap screwing process.

[0029] In this embodiment, by setting the automatic cap screwing mechanism 5 and utilizing the mutual cooperation between the limiting component 504 and the cap screwing component 508, the cap placing and cap screwing processes can be completed simultaneously, with high integration and convenient use. It can effectively improve the efficiency of cap screwing and encapsulation processing. Moreover, when screwing the cap, the telescopic clamping plates 509 will automatically fix the position of the plastic container 6, which can effectively prevent the container from tipping during the cap screwing process. Additionally, in this embodiment, by setting the container conveying mechanism 4 and utilizing the mutual cooperation between the conveying rollers 403 and the conveyor belt 404, the plastic container 6 can be automatically conveyed without manual feeding by the staff, which can not only improve the processing efficiency but also ensure the accuracy during the filling and cap screwing operations.
