Covering device

Abstract

The invention discloses a cover rolling device, which comprises a motor, a transmission device, several rolling knives, a planet gear wheel transmission device, a groove cam, a rotation disc, a dial wheel, and a driving transmission gear wheel. Wherein, said motor via transmission device is connected to the planet gear wheel transmission device; the rolling knives are connected to the planet gear wheel of planet gear wheel transmission device; the groove cam is fixed on frame; the rotation disc under the rolling knives is connected to the driving transmission gear wheel;; the dial wheel is fixed on the rotation disc; the shape of rolling knives is triangle star with arc; the concave and convex parts of triangle star of nearby rolling knives are concave-convex relatively arranged, while the rotations of nearby ones are reversed. The invention has simple structure, high efficiency and better property.

Description

technical field [0001] The invention mainly relates to the field of capping devices for bottle packaging containers in the pharmaceutical and food industries, in particular to a capping device of a rolling knife set type. Background technique [0002] At present, the capping device of the capping machine has two types: the single knife type and the rolling knife group type. The plastic cover is rolled and sealed. The shape of the rolling knife group is a triangular star with a circular arc. Due to the needs of rolling the cap, its outer dimension is basically a certain value. During the working process, the rolling knife group cannot interfere with each other. Their transmission The mechanism adopts the planetary gear type, that is, the central gear drives the planetary gears on the same plane to revolve around itself, and the planetary gears rotate on their own center. The planetary gears have the same parameters, and the center distance between the planetary gears must be ...

[0002] At present, the capping device of the capping machine has two types: the single knife type and the rolling knife group type. The plastic cover is rolled and sealed. The shape of the rolling knife group is a triangular star with a circular arc. Due to the needs of rolling the cap, its outer dimension is basically a certain value. During the working process, the rolling knife group cannot interfere with each other. Their transmission The mechanism adopts the planetary gear type, that is, the central gear drives the planetary gears on the same plane to revolve around itself, and the planetary gears rotate on their own center. The planetary gears have the same parameters, and the center distance between the planetary gears must be greater than the diameter of the addendum circle , due to the constraints of the above two conditions, the device has large dimensions, high mass, high manufacturing cost, and low work efficiency
