Embodiment Construction
[0027] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0028] A large slenderness ratio propellant automatic end surface coating device, such as figure 1 As shown, it includes: positioning roller 1, powder column 2, air outlet 3, dispensing head positioning motor 4, dispensing head lifting cylinder 5, end cover pressing cylinder 6, end cover adsorption device positioning cylinder 7, end cover Rotary cylinder 8, end cap storage barrel 9, end cap jacking motor 10, end cap storage barrel swing cylinder 11;
[0029] Its connection relationship is:
[0030] The two positioning rollers 1 are fixedly connected in parallel, and then fixed on the installation platform through the fixed bracket; the other two positioning rollers 1 are movably installed on the installation platform through the movable bracket, which can realize opening and closing, which is convenient for putting in the powder column 2 and take out,...

The invention relates to a high fineness ratio propellant automation transverse plane coating apparatus, which belongs to the field of mechanical and electrical automation. Under condition of guaranteeing production safety, the automation transverse plane coating apparatus realizes serialization and automation transverse plane coating of a solid propellant drug column. The automation transverse plane coating apparatus comprises a drug column positioning system, a transverse plane gluing system, an end coating sheets storage apparatus, and a transverse plane coating system. Through theory and simulation verification, the apparatus realizes automation and serialization of a coating process of the drug column transverse plane, gluing of the bonding surface of the large transverse plane of the drug column and the coating sheets is uniform, crack or unstick phenomenon cannot be generated between the coating sheets and the drug column, and the quality requirement with a technology standard can be satisfied.
Description
technical field [0001] The invention relates to an automatic end surface coating device of a large slenderness ratio propellant, which belongs to the field of mechanical and electronic automation. Background technique [0002] The traditional end surface covering process is completed manually, which has poor continuity during the process, makes it difficult to guarantee safety, and also limits work efficiency. The main process is to pour the selected qualified powder into the inner hole with a certain proportion of nitro paint cloth paint, and form a certain thickness of nitro paint cloth coating on the surface of the inner hole of the powder, so as to play a role in the initial combustion of the charge. The role of short-term combustion. And the large end surface of the powder column after the inner hole is coated is covered with a prefabricated nitro paint cloth. The whole process is manually operated, and the coating solution contains acetone, a volatile solvent, result...
