[0032] The curling unit includes a second cylinder 9 and a pressing plate 10 .

[0033] Among them, the pressing plate 10 is installed at the output end of the second cylinder 9, and the second cylinder 9 is installed on the frame 1 to drive the pressing plate 10 to move up and down to curl the paper tube 01.

The surface of the forming column 15 cooperates with the curling of the paper tube 01. The forming column 15 is truncated cone-shaped, and the bottom of the forming column 15 is arc-shaped.

[0036] The turntable 16 is rotatably connected to the center of the frame 1 , and is provided with a plurality of station slots 17 for placing the paper tubes 01 . The gluing head 7 , the pressing plate 10 and the forming column 15 are arranged on the movable path of the station slots 17 .

[0037] Working principle: install the paper tube 01 to be curled in the station slot 17 on the turntable 16 and rotate the turntable 16 so that the paper tube 01 to be curled corresponds to the glue coating head 7, pour the glue liquid into the material box 2 from the feed port on the material box 2, cooperate with the diaphragm pump 3 to transport the glue liquid in the material box 2 to the glue liquid pipe 4, and transport it to the glue coating head 7 through the glue outlet pipe 5 connected to the glue liquid pipe 4, cooperate with the glue liquid pipe 4 to extend into the channel 76 and correspond to the bottom of the chamber 73, so that the glue entering the glue coating head 7 enters the chamber 73 of the outer shell 71 through the channel 76 on the glue squeezing block 72, and the liquid level of the glue liquid in the chamber is as shown in Figure 2 As shown in the dotted line position, the first cylinder 6 works to drive the glue dispensing pipe 5 to move so that the glue coating head 7 enters the paper tube 01, and the clamping plate 8 on the glue coating head 7 contacts the edge of the paper tube 01, and the glue dispensing pipe 5 drives the glue coating head 7 to continue to move into the paper tube 01, and the clamping plate 8 contacts the upper edge of the paper tube 01 so that the glue squeezing block 72 connected to the glue dispensing pipe 5 moves in the chamber 73 to squeeze the glue liquid in the chamber 73, so that the glue liquid fills the gap between the glue squeezing block 72 and the inner wall of the chamber 73 and overflows from the overflow hole 75 to coat the inner wall of the edge of the paper tube 01. After the gluing work of the paper tube 01 is completed, the first cylinder 6 drives the glue coating head 7 to move upward so that the glue coating head 7 is separated from the paper tube 01; Then, the rotating turntable 16 is coordinated to make the paper tube 01 correspond to the pressing plate 10, and the un-glued paper tube 01 on the adjacent station slot 17 is coordinated with the gluing head 7 to carry out the gluing work of the next paper tube 01, so as to improve the work efficiency. At the same time, the second cylinder 9 drives the pressing plate 10 to move toward the paper tube 01 that has completed the gluing work, and makes the curling ring 23 on the pressing plate 10 press the edge of the paper tube 01, and cooperates with the inner wall of the curling ring 23 to form an arc, so that the edge of the glued paper tube 01 forms an inverted curling edge. At this time, the formed curling edge is attached to the inner wall of the glued paper tube 01, so that the formed curling edge is more firm, and the curling stability of the paper tube 01 is improved, and it is not easy to fall apart. After the curling work of the paper tube 01 is completed, the second cylinder 9 drives the pressing plate 10 to move upward, so that the curling ring 23 on the pressing plate is separated from the paper tube 01 and away from the paper tube 01; The turntable 16 is rotated again so that the paper tube 01 with curled edge is corresponding to the forming column 15, and the adjacent paper tube 01 that has completed the gluing work is corresponding to the pressing plate 10 to complete the curling work, thereby improving the work efficiency. At the same time, the third cylinder 11 works to drive the forming column 15 to move into the curled paper tube 01 so that the forming column 15 contacts the curled edge. The bottom of the forming column 15 is arc-shaped so that the forming column 15 can better enter the paper tube 01. When the forming column 15 is supported in a truncated cone shape and continues to move into the paper tube 01, the outer surface of the forming column 15 can contact the curled edge of the paper tube 01 and squeeze the curled edge of the paper tube 01, thereby The curled edge of the paper tube 01 is better adhered to the inner wall of the paper tube 01 coated with glue to further improve the stability of the curled edge, avoid the formed curled edge from being easily scattered, make the paper tube 01 packaging product more solid, and improve practicality. Then, the third cylinder 11 drives the forming column 15 away from the paper tube 01 to facilitate the rotation of the turntable 16 so that the curled paper tube 01 and the forming column 15 are misaligned, so that the curled paper tube 01 is conveniently removed from the station slot 17 to complete the curling work of the paper tube 01, and then the paper tube 01 to be curled is placed in the corresponding empty station slot 17 to facilitate the next round of curling work of the paper tube 01, which is highly practical. To sum up, it is possible to apply glue to the edge of the inner wall of the paper tube 01, avoiding the need for manual gluing, making it easier for the curled edge formed by the paper tube 01 to be more firmly adhered to the glued portion of the inner wall of the paper tube 01, making it difficult for the curled edge formed on the edge of the paper tube 01 to spread apart, which is beneficial to enhancing the curling stability, avoiding the problem of curling deformation and curling of the paper tube 01, improving the overall stability and durability of the paper tube 01, realizing automatic gluing and curling processing, and improving practicality.

[0038] The outer shell 71 is transparent, which facilitates the glue to enter the cavity 73 and timely replenish the glue in the cavity 73 to avoid the problem that the glue cannot overflow from the overflow hole 75 to the outer wall of the outer shell 71 when the glue squeezing block 72 squeezes the glue due to insufficient glue in the cavity 73. The bottom of the outer shell 71 is arc-shaped, which facilitates the glue coating head 7 to enter the paper tube 01 more smoothly. The bottom of the glue squeezing block 72 cooperates with the bottom of the outer shell 71 to facilitate the glue to rise to the overflow hole 75 better when the glue squeezing block 72 squeezes the glue and overflow from the overflow hole 75 to the inner wall of the edge of the paper tube 01, which is conducive to better gluing the edge of the paper tube 01.

The forming column 15 is provided with an air pipe 26 connected to the cold air chamber 24. The frame 1 is provided with an air cooler 27. The air pipe 26 is connected to the output end of the air cooler 27. When the forming column 15 moves into the paper tube 01 and squeezes the curled edge formed on the paper tube 01 so that the curled edge is better adhered to the inner wall of the paper tube 01 coated with glue, the cold air blower 27 works to generate cold air which enters the cold air chamber 24 of the forming column 15 through the air pipe 26 and is blown out through a plurality of cold air holes 25 connected to the cold air chamber 24, thereby drying the glue on the inner wall of the paper tube 01 used to adhere the curled edge of the paper tube 01, which helps the curled edge of the paper tube 01 to be adhered to the glue-coated part of the inner wall of the paper tube 01 faster and more firmly, further avoiding the problem of curling of the paper tube 01, thereby improving practicality.

[0042] The turntable 16 is provided with a mounting column 35 which is detachably connected to the station slot 17. The mounting column 35 is provided with a placement slot 36 which matches with the paper tube 01. The paper tube 01 is placed in the placement slot 36 and one end of the paper tube 01 extends out of the placement slot 36. The paper tube 01 is placed in the placement slot 36 of the mounting column 35, which is convenient for installing the paper tube 01 to be curled and removing the curled paper tube 01. The operation is simple. When the pressing plate 10 curls the edge of the paper tube 01 through the curling ring 23, the paper tube 01 is placed The placement groove 36 of the mounting column 35 prevents the paper tube 01 from being displaced or tilted during the pressing process, which is conducive to forming a uniform curling edge, improving the curling accuracy and stability, and further improving practicality.
