[0029] In summary, in actual use, in the initial state, the first glue coating and pressing arm assembly 200 and the second glue coating and pressing arm assembly 300 are longitudinally arranged on the glue coating and pressing frame assembly 100, and the semi-finished telescopic tube support arm assembly 400 is also in a longitudinal arrangement. The double-sided gear arm 112 is driven to reciprocate left and right by the first cylinder 111. At this time, the double-sided gear arm 112 is meshed with the gear wheel 203, that is, at this time, the first glue coating and pressing arm assembly 200 and the second glue coating and pressing arm assembly 300 are transposed left and right on the glue coating and pressing frame assembly 100. When the first gluing and pressing arm assembly 200 is rotated left and right on the gluing and pressing frame assembly 100, since the fixed pulley 106 is fixed, the fixed pulley 106 has a traction force on the shaft pulley 402 through the belt 113, and the diameter of the shaft pulley 402 is consistent with the diameter of the fixed pulley 106. When the first gluing and pressing arm assembly 200 swings, the support arm shaft 401 will rotate in the opposite direction through the cooperation of the fixed pulley 106, the belt 113 and the shaft pulley 402. Since the diameter of the shaft pulley 402 is The diameter of the fixed pulley 106 is consistent, that is, the first glue coating and pressing arm assembly 200 rotates a certain degree, and the semi-finished telescopic tube support arm assembly 400 at the end of the first glue coating and pressing arm assembly 200 rotates a certain degree in the opposite direction. In short, through the above-mentioned structure, when the first glue coating and pressing arm assembly 200 swings left and right, the semi-finished telescopic tube support arm assembly 400 at the end of the first glue coating and pressing arm assembly 200 is always in a longitudinal arrangement state, which is convenient for subsequent glue coating and pressing docking. At the same time, the transposition inner arm 206 and the transposition inner arm 206 of the present invention are A telescopic arm structure is arranged between the outer arms 201, and the transposed inner arm 206 slides in the guide rails of the vertical rail groove 104 and the arc rail groove 105 through the rolling shaft rod 205. When sliding in the arc rail groove 105, it is convenient for the first gluing and pressing arm assembly 200 to be transposed left and right on the gluing and pressing frame assembly 100. When sliding in the vertical rail groove 104, it is convenient for the semi-finished telescopic tube support arm assembly 400 at the end of the first gluing and pressing arm assembly 200 and the semi-finished telescopic tube support arm assembly 400 at the end of the second gluing and pressing arm assembly 300 to be in a longitudinal pressing and docking structure.

[0030] In the above structure, that is, when the first glue coating and pressing arm assembly 200 and the second glue coating and pressing arm assembly 300 swing synchronously toward the glue injection pump 110, the small-diameter telescopic tube 500 is fixed to the first glue coating and pressing arm assembly 200 through the semi-finished telescopic tube support arm assembly 400, and the large-diameter telescopic tube 600 is fixed to the second glue coating and pressing arm assembly 300 through the semi-finished telescopic tube support arm assembly 400. At this time, the small-diameter telescopic tube 500 on the first glue coating and pressing arm assembly 200 and the large-diameter telescopic tube 600 on the second glue coating and pressing arm assembly 300 are respectively inserted into the sponge pad seat groove 114 and outside the bottom sponge pad 108. In this way, the gluing of the outer wall of the small-diameter telescopic tube 500 and the inner wall of the large-diameter telescopic tube 600 are achieved.

[0031] In the above structure, after the above-mentioned gluing is completed, the first gluing and pressing arm assembly 200 and the second gluing and pressing arm assembly 300 are synchronously swung to the other side of the gluing and pressing frame assembly 100, that is, the side away from the glue injection pump 110. During the swinging process, the small-diameter telescopic tube 500 on the first gluing and pressing arm assembly 200 and the large-diameter telescopic tube 600 on the second gluing and pressing arm assembly 300 are in a structure of continuous docking and pressing. In this way, when the first gluing and pressing arm assembly 200 and the second gluing and pressing arm assembly 300 are swung left and right on the gluing and pressing frame assembly 100, the gluing and longitudinal pressing and docking of the inner and outer arms of the small-diameter telescopic tube 500 and the large-diameter telescopic tube 600 are completed.

[0032] In the above structure, the small-diameter telescopic tube 500 and the large-diameter telescopic tube 600 of the present invention are fixed to the first gluing and pressing arm assembly 200 and the second gluing and pressing arm assembly 300 through the semi-finished telescopic tube support arm assembly 400. When fixed, in the initial state, the first gluing and pressing arm assembly 200 and the second gluing and pressing arm assembly 300 are longitudinally arranged on the gluing and pressing frame assembly 100. At this time, the small-diameter telescopic tube 500 is sleeved on the semi-finished telescopic tube support arm assembly 400, and the sliding frame seat 406 is driven to slide downward by the second cylinder 404. When the sliding frame seat 406 slides downward on the fixed vertical frame arm 405, the first linkage arm 407 and the second linkage arm 408 are connected. With the cooperation of the linkage arm 410, multiple arc-shaped resistance plates 409 form a synchronously extended structure outside the fixed base column 411. At this time, the small-diameter telescopic tube 500 is centrally fixed on the semi-finished telescopic tube support arm assembly 400, and the fixing method of the large-diameter telescopic tube 600 is consistent with the fixing method of the small-diameter telescopic tube 500. In this way, the small-diameter telescopic tube 500 and the large-diameter telescopic tube 600 can be centrally fixed on the first glue-coated pressing arm assembly 200 and the second glue-coated pressing arm assembly 300. During the longitudinal pressing and docking, the smoothness of the longitudinal pressing and swallowing of the small-diameter telescopic tube 500 and the large-diameter telescopic tube 600 can be guaranteed.

[0033] In the above structure, a telescopic structure is arranged between the transposition outer arm 201 and the transposition inner arm 206 of the present invention. When the left and right transposition action is performed, in order to ensure the tension of the belt 113 between the fixed pulley 106 and the shaft pulley 402, the push arm 208 is used to drive the push wheel 209 to contact the belt 113 (the specific structure of the push arm 208 is an elastic contact arm with a telescopic structure, which is a conventional technology and will not be described in detail). In this way, it is possible to ensure that the fixed pulley 106 has sufficient traction on the shaft pulley 402, thereby ensuring that when the subsequent first gluing and pressing arm assembly 200 swings on the gluing and pressing frame assembly 100, the small-diameter telescopic tube 500 on the first gluing and pressing arm assembly 200 is always in a longitudinally downward placement structure.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
