Description

Technical Field

[0001] The utility model belongs to the technical field of cover processing, in particular to a cover supply device for gluing and conveying covers. Background Art

[0002] Metal lids such as can lids and bottle caps are widely used in packaging due to their durability, good sealing effect, and convenient transportation. As lids are used more and more widely in packaging, the market demand for lids in packaging is huge.

[0003] In the existing technology, the production process of metal caps such as can caps and bottle caps usually involves punching and stretching the cut sheet material into the shape of the cap using a punching machine, and then applying glue to the cap using a glue injection machine. There are two main ways to convey the caps punched out by the punching machine to the glue injection machine for gluing: one is to manually place the caps one by one under the glue injection machine, and then the glue injection machine applies glue to the caps; the other is to set a cap feeding and conveying structure with multiple curved paths between the punching machine and the glue injection machine bracket, and use a cap feeding and conveying machine to deliver the caps. The existing cap feeding and conveying method has the following shortcomings:

[0004] 1) The efficiency of manual cap feeding is very low, and the caps need to be placed manually, which affects the gluing process of the caps. The degree of automation of cap feeding and gluing is low, and the work efficiency is low, which limits the production and processing of the caps, resulting in production supply exceeding demand and failing to meet the packaging needs of users;

[0005] 2) The existing cap feeding conveying structure needs to set up multiple cap feeding conveying lines with curved routes. Each cap feeding conveying line needs to be set up as a roller conveying structure composed of multiple rollers. The roller conveying structure needs to be set up with a large number of rollers, and a transmission structure needs to be set up between two adjacent rollers. The number of rollers and transmission structures required for a single roller conveying structure is relatively large, and its structure is relatively complex and inconvenient to install. In addition, when multiple cap feeding conveying lines with curved routes are set up, the caps need to be bent and transferred multiple times during the conveying process, which cannot ensure the stability of the cap conveying process and the continuous feeding of the caps for gluing cannot be ensured.

The first guide slide rod 21 and the second guide slide rod 22 are spaced apart from each other and distributed on the slide support frame 23 at an inclined fixed interval. The distance between the first guide slide rod 21 and the second guide slide rod 22 forms the cover feeding slide 2; the cover pushing conveyor line 3 includes a cover pushing structure 31, a rocker structure 32, and a cover pushing drive structure 33. One end of the rocker structure 32 is connected to the cover pushing structure 31, and the other end of the rocker structure 32 is connected to the cover pushing drive structure 33 by transmission. The utility model connects the front end of the cap feeding conveyor line 1 with the discharge conveying end of the punching machine, and uses the cap feeding conveyor line 1 to send the cap body 4 punched by the punching machine to the cap feeding slide 2. The first guide slide rod 21 and the second guide slide rod 22 are fixed on the slide support frame 23 in an inclined manner, so that the cap body 4 slides downward on the cap feeding slide 2 by its own gravity, so that the cap body 4 quickly falls to the front end of the cap pushing conveyor line 3. The cap pushing structure 31, under the driving and pushing action of the cap pushing drive structure 33 and the rocker structure 32, will automatically push the cap body 4 to the glue injector 5, and the glue injector 5 will automatically push the cap body 4 to the glue injector 5.
