Description

Technical Field

[0001] The invention relates to the technical field of a steel drum production line, and in particular to a cover removal device for a steel drum cover production line. Background Art

[0002] During the production process of steel drums, the steel plates are first rolled into barrels, then stamped into barrel bodies, and then the barrel bottoms and barrel covers formed by the pressure of the steel plates are fixed to the barrel bodies, and then the steel drums are spray-painted, dried, and finally covered.

[0003] At present, in the production process of steel drums, except for the covering process, the rest of the processes have basically been automated. Although there are some automatic covering devices for the covering process of steel drums, the automation efficiency of steel drum covering is low, and there is no special automatic production line for steel drum covering. There are only some automatic equipment for individual processes. Moreover, the equipment involved in the process of steel drum covering cannot be connected into a production line due to different production speeds. Even if they are connected into a production line, there are many processes involved in the covering process, at least involving: 1. Removing the cover placed on the mouth of the steel drum during painting, 2. Cooling the steel drum and replacing the air in the steel drum, 3. Injecting inert gas into the steel drum to facilitate the later detection of the sealing performance of the steel drum, 4. Installation of the large and small covers of the steel drum, 5. Installation of the rain cover of the small cover of the steel drum; as long as the efficiency of a certain process is low, the production efficiency of the entire production line will be low. Therefore, there is currently no production line with relatively high production efficiency and high degree of automation on the market for automatic covering production after steel drum painting.

[0004] In order to solve the above technical problems, the applicant has previously applied for a patent for "Automatic Covering Production Line after Steel Drum Painting", but the overall structure is relatively complex, the production cost is high, the control circuit is complex, and it is easy to make mistakes during operation; in addition, in actual use, it is found that the dust cover of the steel drum cannot be sucked away by the electromagnet sometimes when the steel drum is removed. After analysis, it is found that this is mainly because the edge of the dust cover surface is connected to the top surface of the steel drum by a dried paint film, and because the steel drum itself is also a magnetic conductor, the magnetic force of the electromagnet will be interfered by the loss of the steel drum, resulting in a smaller magnetic force on the dust cover; in addition, as the steel drum is conveyed, the angle positioning of the steel drum will fail in the subsequent process, and the positioning requirements of the early process are not high compared to the subsequent positioning requirements; in addition, the production efficiency of the entire production line is still expected to be higher. Summary of the invention

[0005] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a cover removal device for a steel drum cover production line, which, through the action of a vibrating plate, allows the paint film connecting the edge of the dust cover and the drum top to be vibrated off before the dust cover of the steel drum is removed, thereby avoiding damage to the paint surface of the drum top when the dust cover is directly removed;

[0006] Through the action of the blocking rod, the steel barrel at the top vibration station of the steel barrel can be positioned and the remaining steel barrels on the steel barrel feeding conveyor can be ensured not to affect the conveying of the steel barrel after the vibration is completed. In addition, the conveying rhythm of the steel barrel after the vibration is consistent with the conveying rhythm of the steel barrel stepping conveyor, thereby facilitating the automatic conveying docking between different conveying devices.

[0007] Through the structure and position setting of the swing rod B, it can be ensured that the swing rod B is only in contact with the large barrel mouth of the steel drum for positioning. Since the dust cover and the corresponding barrel mouth of the steel drum are only connected for placement, the positioning accuracy requirement itself is not high. Through the contact between the swing rod B and the edge of the large barrel mouth, the positioning requirement of removing the dust cover can be met;

[0008] By replacing the dust cover removal structure with a cover removal fixture and using the assistance of a pressure plate, the quality of cover removal can be better guaranteed compared to the original method of electromagnet adsorbing the dust cover. The dust cover is not adsorbed and affects the subsequent production process, and additional noise is generated when the electromagnet adsorbs the dust cover.

[0056] Eighth, in the cover removal device of the steel drum cover production line of the present invention, the steel drum is cooled by aeration through multiple aeration cooling stations, thereby ensuring the cooling effect inside the steel drum.

[0057] Ninth, the capping device of the steel barrel cap production line of the present invention can simultaneously inflate with inert gas during the process of screwing the small cap on the small barrel mouth at the first capping station, thereby further improving production efficiency.
