Automatic cover pressing machine of plastic covers

Abstract

The invention discloses an automatic cover pressing machine of plastic covers. The automatic cover pressing machine of the plastic covers is characterized by comprising a pressing mechanism used for tightly pressing the plastic covers on cans and a conveying mechanism used for conveying the plastic covers to the entry of the pressing mechanism. The pressing mechanism can automatically adjust the degree of tightness of cover pressing through a tightness self-adjusting spring mechanism according to the bending and the deformation of the plastic covers, the phenomenon of pressure leakage is effectively avoided, and continuous production can be carried out on the cans with various heights. The conveying mechanism places the plastic covers in a sliding channel one by one through a vacuum suction cup to carry out automatic gravity conveying, the whole conveying mechanism can work continuously and stably, the requirements for the flatness of the plastic covers is not high, and the situation that conveying is stopped due to slight distortion of the plastic covers is avoided.

Description

technical field [0001] The invention belongs to the technical field of milk powder packaging equipment, and in particular relates to an automatic plastic cap capping machine for press-fitting a plastic cap and a milk powder tin can together. Background technique [0002] Milk powder is generally packed in iron cans with good sealing performance, and iron cans generally need a plastic cover to seal the lid. In general capping machines, the conveyor belt drives the iron cans to move, and the belt in the middle of the can body stabilizes the position of the iron cans. , and then the plastic cover falls on the tank body, and the plastic cover is compressed by a pneumatic or hydraulic pressure mechanism, but if the plastic cover is placed slightly skewed or the plastic cover is deformed, it may cause pressure leakage or pressure. In addition, the compression of iron cans of different heights requires complex adjustments and even needs to change the production line, and continuous...

[0002] Milk powder is generally packed in iron cans with good sealing performance, and iron cans generally need a plastic cover to seal the lid. In general capping machines, the conveyor belt drives the iron cans to move, and the belt in the middle of the can body stabilizes the position of the iron cans. , and then the plastic cover falls on the tank, and the plastic cover is compressed by a pneumatic or hydraulic pressure mechanism. However, if the plastic cover is slightly skewed or deformed when placed, it may cause pressure leakage or pressure. In addition, the compression of iron cans of different heights requires complex adjustments and even needs to change the production line, so continuous production cannot be carried out, and the plastic cap conveying channel of the existing capping machine is only slightly larger than the plastic cap. If the plastic cover is slightly deformed and twisted, it will block the conveying channel, causing production to stop
