Description

Technical Field

[0001] The present invention belongs to the technical field of capping machines, and particularly relates to a novel capping mechanism. Background Art

[0002] As a packaging device widely used in industries such as food, beverage, and pharmaceutical, the main function of a capping machine is a machine that presses plastic raw materials into bottle caps by applying a certain pressure. Traditional capping machines mostly use a hydraulic system as the power source and utilize the pressure transmission of hydraulic oil to achieve the capping action. Although the hydraulic system has certain advantages in providing a large output force and smooth movement, with the continuous improvement of industrial automation and environmental protection requirements, the application of the hydraulic system in capping machines has gradually exposed many drawbacks.

[0003] Firstly, the maintenance cost of the hydraulic system is relatively high. The hydraulic system consists of complex components such as hydraulic pumps, hydraulic cylinders, control valves, oil tanks, and pipelines. These components need to be maintained and replaced regularly. In particular, the aging problems of hydraulic oil and seals increase the maintenance difficulty and cost of the equipment. Secondly, the hydraulic system is prone to oil leakage, which not only causes environmental pollution but also may affect the normal operation of the equipment and reduce production efficiency. In addition, the energy loss of the hydraulic system is relatively large during operation, especially in the no-load or low-load state, and the system efficiency is low, resulting in energy waste. The noise generated by hydraulic pumps and valve components during operation will affect the working environment, and the response speed of the system is slow, making it difficult to meet the requirements of high precision and high speed in modern production lines. Finally, the viscosity of hydraulic oil is relatively sensitive to temperature changes. Under extreme temperature conditions, the performance of the system may be affected, resulting in unstable capping quality. In summary, although the hydraulic system has played an important role in capping machines, its inherent drawbacks have gradually become a bottleneck restricting the improvement of equipment performance. Therefore, exploring a more efficient, environmentally friendly, and reliable power system to replace the hydraulic system has become an important direction for the development of capping machine technology.

[0004] Therefore, how to provide a novel capping mechanism that can solve the above technical problems is one of the problems that those skilled in the art urgently need to solve. Summary of the Invention

[0005] To solve the above problems, the present invention uses a servo motor reducer to drive a rack and pinion structure, and uses the thrust generated by the rack as the driving force and pressing force of the bottle cap bottom mold. The present invention adopts the following technical solutions:

A plurality of capping head components are arranged at the upper end of the capping machine frame, and a plurality of bottle cap bottom mold components are arranged at the lower end of the capping machine frame corresponding to the capping head components one by one;

[0007] Each of the bottom die assemblies of the bottle cap includes a bottom die of the bottle cap, a speed reducer, and a rack; the rack is movably connected to the frame of the capping machine, and the upper end of the rack is fixedly connected to the bottom die of the bottle cap, and the lower end thereof is in gear transmission connection with the gear fixedly connected to the output end of the speed reducer; the speed reducer is fixedly arranged at the bottom of the frame of the capping machine.

[0008] Preferably, a press head mounting seat is provided at the upper end of the frame of the capping machine, and a bottom die mounting seat of the bottle cap is provided in the middle; a plurality of the press head assemblies are evenly distributed on the press head mounting seat; the bottom dies of the bottle cap are evenly distributed on the bottom die mounting seat of the bottle cap, and the rack passes through the inside of the bottom die mounting seat of the bottle cap, and the bottom die mounting seat of the bottle cap is fixedly connected to the frame of the capping machine.

[0009] Preferably, the lower half of the rack is set to the shape of the rack tooth profile corresponding to the gear, and the upper half is a smooth cylinder and is slidably connected with a bushing.

[0010] Preferably, the bushing is fixedly connected to the bottom die mounting seat of the bottle cap, and the rack slides up and down in the hole at the center of the bushing.

[0011] Preferably, the output end of the speed reducer is fixedly connected to the gear, and a speed reducer support seat is also arranged between the speed reducer and the gear.

[0013] Preferably, a servo motor is further included, and the servo motor is fixedly connected to the lower end of the speed reducer.

[0014] Beneficial effects:

[0015] By adopting the meshing transmission of the gear and the rack, the gear drives the rack to reciprocate vertically. The front end of the rack is fixedly connected to the bottom die of the bottle cap. Through the reciprocating movement of the rack, the thrust generated by the rack can be used as the driving force and pressing force of the bottom die of the bottle cap to drive the bottom die of the bottle cap to open and close the mold, so as to realize the capping operation; the defects such as leakage of the original hydraulic system are eliminated, the production of the hydraulic station is saved, the cost is greatly saved, the energy consumption is reduced, and the system efficiency is effectively improved.
