Barrel cover pre-coiling and glue spraying machine

Abstract

The invention discloses a barrel cover pre-coiling and glue spraying machine. The top of a table-board of a rack is connected with a supporting plate in a vertically movable manner, and barrel covers are conveyed on the top face of the supporting plate; the supporting plate is provided with a through hole A, a through hole B and a through hole C in sequence in the conveying direction of the barrel covers, and a material preparation station, a pre-coiling station and a glue spraying station are arranged at the positions, corresponding to the through hole A, the through hole B and the trough hole C, on the rack; a barrel cover conveying device is arranged on the supporting plate, the conveying device is movably connected with a fixing frame at the top of the rack, and the supporting plate is connected with the table-board of the rack through pistons C in a vertically movable manner. It is known from the above structure of the barrel cover pre-coiling and glue spraying machine that two processes of pre-coiling and glue spraying of the barrel covers are divided into two stations to perform operation on different barrel covers simultaneously, therefore operation time of each process is saved, the bottleneck problem of the production speed of a whole barrel body is solved, and thus the production efficiency of the barrel body is improved.

Description

technical field [0001] The invention relates to the technical field of metal barrel production, in particular to a barrel cover pre-roll glue spraying machine. Background technique [0002] With the continuous development and improvement of production automation, the production of metal barrels can gradually realize automatic production, but in the entire production cycle, there are two bottlenecks in production efficiency, one is the metal plate rolled and welded into a barrel structure process, the second is the pre-roll glue spray process. [0003] For the former, due to the current limited technical capabilities, it can only roll 7-8 barrels per minute for the time being, which cannot significantly improve efficiency. If one more barrel is rolled per minute on this basis, the cost of equipment is much higher than Equipment that rolls 7-8 barrels per minute, so the price is low. [0004] As for the pre-rolling glue spraying process, the old-fashioned pre-rolling glue sp...

Problems solved by technology

For example, the structure of the invention patent with the application number of 2016204140890, because the pre-rolling and glue spraying are operated at one station, the time consumed by the station is relatively long, so that the entire production line needs to be equipped with multiple pre-rolling glue spraying machines at the same time , which increases the production cost of the enterprise; in addition, because the pre-rolling and glue spraying processes of the barrel cover are operated at the same station, the station speed cannot be adjusted

In actual production, the lid needs to maintain a high speed during pre-rolling, otherwise it will lead to poor curling surface quality of the lid and increase the wear of the pre-rolling mold; while the speed of the lid during glue spraying requires a higher speed. Low, otherwise the thickness of the sprayed glue cannot be guaranteed, and the glue in the curling edge is thrown out of the curling edge by the centrifugal force generated by the faster speed when it is not solidified, resulting in waste of glue and pollution of pre-rolled glue spraying The working environment around the machine, due to the uncertainty of the glue thrown out, further cannot guarantee the thickness of the glue sprayed in the curling
