An air cushion floating non-contact waxing mechanism

Abstract

The invention relates to an air-cushion floating non-contact wax coating mechanism which is characterized in that a wax coating spindle penetrates through axial center holes of a first expansion sleeve and a second expansion sleeve sequentially; an air distribution hub is arranged on the profile surface of the first expansion sleeve in an embedding manner; a star wheel hub is arranged on the profile surface of the second expansion sleeve in an embedding manner; a wax coating star wheel is fixedly connected with the star wheel hub; air guide holes are formed in the edge of the wax coating starwheel; a closed space is formed among the air distribution hub, a star wheel hub and a wax coating star wheel; vacuum spacing blocks and compressed air spacing blocks are arranged inside the closed space; the closed space is divided by the vacuum spacing blocks and the compressed air spacing blocks into vacuum adsorption areas and compressed air action areas; and the vacuum adsorption areas or thecompressed air action areas in the closed space communicate through the air guide holes. According to the technical scheme, pop-top cans are prevented from being in contact with a metallic wax coating star wheel body when coated with wax, the rejection rate during the production can be reduced, the structure can be simplified, the maintenance cost can be reduced, the downtime can be shortened, and the production efficiency can be improved.

Description

technical field [0001] The invention relates to an air cushion floating non-contact waxing mechanism, and relates to the technical field of pop can production. Background technique [0002] With the vigorous development of the can market, the demand is increasing year by year, and the competition in the industry is becoming increasingly fierce, which prompts the can production plant to continuously improve the production efficiency of the can and reduce the production cost, so as to have a stronger market competitiveness. This technical solution should be implemented under this background And born. [0003] The existing wax-coated star wheel works under vacuum adsorption, and the wax-coated rubber rollers driven by two gears drive the cans to rotate. When the cans rotate, they need to be in contact with the driving rubber rollers and the metal star wheel body. In this case, "can body scratches" are very easy to occur, and the scratched cans will be regarded as waste product...

AI Technical Summary

Problems solved by technology

[0003] The existing wax-coated star wheel works under vacuum adsorption, and the wax-coated rubber rollers driven by two gears drive the cans to rotate. When the cans rotate, they need to be in contact with the driving rubber rollers and the metal star wheel body. In this case, "can body scratches" are very easy to occur, and the scratched cans will be regarded as waste products in subsequent production and will be rejected, resulting in an increase in the waste rate of can production

In addition, due to the characteristics of the rubber material of the waxed rubber roller, it is also very easy to be damaged during work. After the damage occurs, it needs to be replaced in time, the equipment is shut down, and the production is suspended, which reduces the production efficiency and increases the cost of production and maintenance.
