The center seat 32 is fixedly connected to the support ring 33 through a plurality of groups of connecting rods 31. The top of the supporting assembly 38 contacts the drum paper and fixes the drum paper through friction and suction. The motor 36 drives the center seat 32 to rotate, thereby driving the drum paper to rotate. The telescopic rod 22 sends the gluing assembly 23 to a suitable height, thereby gluing and pasting the edge of the drum paper.

[0025] It should be noted that the glue coating component 23 is located at the top edge of the installation groove 12 .

[0026] See also Figure 3 The glue coating component 23 includes a mounting plate 233, a limiting groove 236 is provided on the front end surface of the mounting plate 233, a rack 231 is slidably connected in the limiting groove 236, a rubber wheel 237 is installed at the end of the rack 231 away from the support frame 21, a driving groove 232 is provided on the side wall of the limiting groove 236, a driving gear 235 is rotatably connected in the driving groove 232, and the driving gear 235 is meshed with the rack 231.

[0027] Specifically, a driving shaft is fixedly connected to the bottom of the driving gear 235, and the driving shaft extends through the bottom of the driving groove 232 and is fixedly connected to a knob 234. An anti-slip sleeve is provided on the lower end surface of the knob 234. The driving gear 235 can be driven to rotate by rotating the knob 234. The driving gear 235 engages the rack 231 to move the rack 231 in the limiting groove 236, thereby adjusting the lateral position of the rubber wheel 237.

[0028] It should be noted that the rubber wheel 237 is connected to the glue injection gun through a hose. The rubber wheel 237 is in the shape of a frustum, and the top area is larger than the bottom area, which can improve the uniformity of the contact between the drum paper and the rubber wheel 237 when rotating.

[0030] Specifically, the support bowl 381 is bowl-shaped and made of rubber material. When the drum paper is placed on the upper end of the support bowl 381, the support bowl 381 is deformed, generating suction to fix the drum paper, so as to prevent the drum paper from being displaced by the centrifugal force and the force of the slide groove 37 during rotation, thereby affecting the uniformity of glue coating. Several groups of inclined surfaces are located directly below the cone. When the cone moves downward, the inclined surface is pushed, so that the slide rod 382 drives the support rod 386 to move outward. At the same time, the limiting ring 383 on the surface of the slide rod 382 compresses the elastic component 384 to move closer to the inner wall of the accommodating groove 35, thereby increasing the position radius of the support bowl 381. When the cone moves upward, the elastic component 384 pushes the limiting ring 383, so that the slide rod 382 drives the support rod 386 to move toward the center of the circle. At this time, the position radius of the support bowl 381 is reduced, and the different sizes of the composite drum paper at each stage in the preparation process can be fixed to improve the stability of glue coating.

[0038] Working principle: Before use, place the drum paper carcass on the upper end of several groups of supporting bowls 381, and gently push the drum paper to deform the supporting bowls 381, so that the supporting bowls 381 discharge the internal air and suck the lower end surface of the drum paper, and the telescopic rod 22 works to move the glue coating component 23 to a suitable height, and then turn the knob 234 to make the driving gear 235 engage the rack 231, so that the rack 231 drives the rubber wheel 237 to move, and when the rubber wheel 237 moves to the edge of the carcass and fits with the edge of the carcass, stop turning the knob 234, start the motor 36, and the motor 36 drives the center seat 32 to rotate, so that the carcass on the upper end of the supporting bowl 381 rotates with the center seat 32, and when the carcass rotates one circle Finally, complete the edge gluing, stick the edge to the outer edge of the carcass, remove the carcass and edge complex, turn the anti-slip knob to rotate the drive rod, and the thread cooperates with the threaded hole to make the cone at the bottom of the drive rod move downward. When the cone moves, the outer wall of the cone cooperates with the inclined surface, so that the slide rod 382 drives the support rod 386 to move, thereby moving the support bowl 381 outward to a suitable position. When the slide rod 382 moves, the limit block 385 is located in the horizontal groove at the bottom of the slide groove 37, thereby improving the stability of the movement of the support bowl 381, fixing the carcass and edge complex at the upper end of the support bowl 381, adjusting the position of the rubber wheel 237, and gluing the edge of the carcass and edge complex.
