The centrifugal deaerating machine 2 is positioned at the upper end part of the frame 1, a valve 211 is arranged at the middle position of the rubber tube 21, and when the centrifugal deaerating machine 2 is in a working state, the valve 211 is in a closing state; after the deaeration is finished, a user opens the valve 211, and the glue solution enters the vacuum cavity 11 from the rubber tube 21 and is further poured into the joint; because the glue solution is defoamed and filled in a vacuum environment, the glue solution entering the joint does not contain a large amount of bubbles.
Referring to fig. 4, the surface of the joint of the plate is rough through roughening, so that the contact area between the glue solution and the surface of the joint is larger; the two heating plates 8 of the user are heated, and at the moment, the part of the plate positioned in the notch 31 and the glue solution are heated to generate a certain degree of hot melting, so that the combination effect of the glue solution and the joint is improved.
Referring to fig. 2, a plurality of cooling pipes 4 are fixedly installed on the side wall of the vacuum cavity 11, a user controls the temperature in the vacuum cavity 11 to be reduced by using the cooling pipes 4, compared with natural cooling, glue solution and plates near joints can be rapidly cooled, the glue solution is rapidly solidified to realize the connection of the joints, and the glue solution has a small amount of bubbles, the contact area between the glue solution and the surfaces of the joints is larger, the combination effect is better, and the connection effect of the glue solution to the joints is further improved.
The embodiment of the application provides a processing device for an acrylic conical cylinder joint, which comprises the following implementation principles: the user scrapes the polishing plate 51 on the surface of the joint by using the first air cylinder 5 to carry out napping processing, so that the surface of the joint is roughened; then, filling the glue solution after the defoaming treatment in the centrifugal defoaming machine 2 into a joint through a rubber pipe 21 in the vacuum environment of the vacuum cavity 11, so as to reduce bubbles in the glue solution; finally, the temperature of the two heating plates 8 is controlled to rise, so that the part of the plate positioned in the notch 31 and the glue solution are heated to generate a certain degree of hot melting; the joint is connected after the glue solution is solidified, and as the air bubbles contained in the glue solution are very small, the contact area between the glue solution and the joint surface is larger, the combination effect is better, and the connection effect of the glue solution to the joint is further improved.
The above embodiments are not intended to limit the scope of the present application, so: all equivalent changes in structure, shape and principle of the application should be covered in the scope of protection of the application.
