Inner single-blade type capping method and mechanism

Abstract

The invention discloses an inner single-blade type capping method and an inner single-blade type capping mechanism, and relates to filling and sealing equipment in the technical fields of pharmaceutical machinery and food packaging machinery. The capping mechanism consists of a central shaft (14), a large rotary disc (17), a support disc (13), a cam (12), a pallet (6), a gearwheel (5), a roller (11), a roller guide base (10), a roller guide rod (9), a rolling cutter holder (8), a rolling cutter (7), a returning spring (16), a tension spring column (15), a gland head (3), a gland head transmission gear (4) and a bottle lifter component (1). The method and the mechanism have the characteristics of good capping effect, high efficiency, low energy consumption, small occupied space, good working environment and the like, canbe used for capping bottles such as oral liquid bottles, cillin bottles, large infusion bottles, wine bottles, drinking bottles and the like in the fields of pharmacy, foods and beverages and the like, and can also be used for capping glass bottles, plastic bottles or other bottles in various industries.

Description

technical field [0001] The invention relates to filling and sealing equipment in the technical fields of pharmaceutical machinery and food packaging machinery, in particular to an inner single-knife capping method and a capping mechanism thereof. Background technique [0002] In the field of pharmaceutical machinery and food packaging machinery, capping is an important process in the production of bottled products such as oral liquid bottles, vials, large infusion bottles, alcoholic beverage bottles, etc. Currently, there are four main methods of capping: 1. One is the single-knife outer oblique cutting type; the second is the three-knife type; the third is the center single-knife type; the fourth is the built-in swing single-knife type. The single-knife outer oblique cutting capping method requires mechanisms such as a swing arm and a rotary plate to complete the action. Its structure is more complicated and the stroke of the swing arm is large; while the three-knife cappin...

AI Technical Summary

Problems solved by technology

The single-knife outer oblique-cut capping method requires mechanisms such as a swing arm and a rotary plate to complete the action. Its structure is more complicated and the stroke of the swing arm is large; while the three-knife capping method requires three knives for each bottle. Rolling, the pitch between the bottles of this structure is large, and three rolling knives need to be adjusted for each bottle, and the adjustment workload is large; the center single-knife capping method is to place a rolling knife at the center position, and through rotation, let The bottle is rolled and pressed relative to the cutter head. Due to the errors in the height and diameter of the bottle, it is difficult to ensure the quality of the capping. improve
