[0015] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0016] Reference Figure 1 to Figure 3 The automatic cutting and gluing mechanism of the cover plate of the roll paper packaging machine includes a cutting frame 1, a cutting device 2, a gluing device 3 and a rotating device 4. The cutting frame 1 is provided with a cutting table 5. The rotating device 4 is arranged below the cutting table 5 and connected to the cutting table 5. The cutting device 2 and the gluing device 3 are both arranged on the cutting frame 1 and located on one side of the cutting table 5. The cutting device 2 includes a cutting knife 21, which is located above the cutting table 5. The gluing device 3 includes a gluing hose 31, which corresponds to the cutting table 5. The rotating device 4 includes a rotating motor 41, the output shaft of which is connected to the cutting table 5, and the cutting table 5 is driven to rotate by the rotating motor 41.

[0017] When the cover plate automatic cutting and gluing mechanism of the roll paper packaging machine of the utility model is used, the cover plate to be cut is placed on the cutting table 5, and the rotating motor 41 drives the cutting table 5 to rotate, so that the cover plate rotates with the cutting table 5. As the cutting table 5 rotates, the cutting knife 21 can cut the entire circumference of the cover plate, so that the cover plate is cut to a corresponding size. When the cover plate is cut and rotated, the glue spraying tube 31 sprays glue, so that the glue is sprayed on the cover plate.

[0018] The cutting device 2 also includes a mounting frame 22, a moving motor 23 and a lifting cylinder 24. The cutting frame 1 is provided with a first slide rail 11. The moving motor 23 is a screw stepping motor. The mounting frame 22 is arranged on the first slide rail 11, the moving motor 23 is arranged on the cutting frame 1, the mounting frame 22 is connected to the screw of the moving motor 23, the lifting cylinder 24 is arranged on the mounting frame 22, and the cutting knife 21 is connected to the piston rod of the lifting cylinder 24. Through the various structures of the cutting device 2, when the cover plate needs to be cut, according to the size of the cover plate to be cut, the moving motor 23 works, and the screw of the moving motor 23 pushes the mounting frame 22 to move to the corresponding position along the first slide rail 11, thereby driving the cutting knife 21 to move to the corresponding position, so as to facilitate the cover plate to be cut into the corresponding size. Specifically, when the size of the cover plate is small, the moving motor 23 pushes the cutting knife to move inward; on the contrary, when the size of the cover plate is large, the moving motor 23 drives the cutting knife 21 to move outward.

[0019] When the cutting knife 21 moves to the front and rear position on the first slide rail 11, the cutting table 5 drives the cover plate to rotate, and the piston rod of the lifting cylinder 24 moves downward, pushing the cutting knife 21 to move downward, so that the cutting knife can act on the cover plate to cut the cover plate. When the cutting is completed, the piston rod of the lifting cylinder 24 is pulled upward, driving the cutting knife 21 to move upward and separate from the cover plate.

[0020] The glue spraying tube 31 is arranged on the mounting frame 22, and the nozzle of the glue spraying tube 31 is located on the inner side of the cutting knife 21 (i.e., the side close to the center of the cover plate). Therefore, by setting the position of the nozzle of the glue spraying tube 31, it can be ensured that the glue can be sprayed on the inner side of the edge of the cover plate, so that the cover plate is conveniently fixed to the end surface of the roll of paper by gluing.

[0021] The cover plate automatic cutting and gluing mechanism of the roll paper packaging machine of the utility model also includes a pressing device 6, which includes a pressing cylinder 61 and a pressing plate 62. The cylinder body of the pressing cylinder 61 is fixed on the cutting frame 1 and is located above the cutting table 5. The pressing plate 62 is connected to the piston rod of the pressing cylinder 61, and the pressing plate 62 is arranged corresponding to the cutting table 5. In order to prevent the cover plate from moving when the cutting table 5 rotates, the piston rod of the pressing cylinder 61 is extended so that the pressing plate 62 presses down on the cover plate, ensuring that the cover plate can rotate with the cutting table 5 while having a certain downward pressure to prevent the cover plate from moving, so that the cutting knife can cut the entire circumference of the cover plate.

[0022] The automatic cutting and gluing mechanism of the cover plate of the roll paper packaging machine also includes a feeding device 7, which includes a feeding motor 71, a first gear 72, a second gear 73, a rotating shaft 74, a rotating arm 75, a first suction cup cylinder 76 and a first suction cup frame 77. The feeding motor 71 is located on one side of the cutting frame 1, the first gear 72 is sleeved on the output shaft of the feeding motor 71, the second gear 73 is sleeved on the rotating shaft 74, the second gear 73 is meshed with the first gear 72, one end of the rotating arm 75 is sleeved on the rotating arm 75, the first suction cup cylinder 76 is installed at the other end of the rotating arm 75, the first suction cup frame 77 is connected to the piston rod of the first suction cup cylinder 76, and the first suction cup frame 77 corresponds to the cutting table 5, that is, the first suction cup frame 77 can absorb the cover plate and place it on the cutting table 5.

[0023] In actual use, the cover plates to be cut can be stacked on the side of the entire mechanism. When the cutting knife 21 needs to cut the cover plates, the material taking motor 71 works, and its output shaft drives the first gear 72 to rotate, thereby driving the second gear 73 to rotate; the second gear 73 drives the rotating shaft 74 to rotate, thereby driving the rotating arm 75 and the first suction cup frame 77 to rotate. When the first suction cup frame 77 rotates to the top of the stacked cover plates to be cut, the piston rod of the first suction cup cylinder 76 extends downward, pushing the first suction cup frame 77 downward, so that the suction cup on the first suction cup frame 77 sucks the cover plates tightly. Subsequently, the material taking motor 71 rotates in the opposite direction until the cover plates are located above the cutting table 5. At this time, the first suction cup frame 77 puts down the cover plates to realize automatic material taking of the cover plates, which is convenient for cutting of the cover plates. After the cover plates are completed, the external material taking structure takes away the cut cover plates, which is convenient for the placement and cutting of the next cover plates. Subsequently, the first suction cup frame 77 is reset, which is convenient for automatic material taking of the next cover plates.

[0024] The cover plate automatic cutting and gluing mechanism of the roll paper packaging machine of the utility model also includes a push rod 9, a push rod cylinder 10 and a second slide rail 20. The second slide rail 20 is fixed on the cutting frame 1. The push rod 9 cooperates with the second slide rail 20. The push rod cylinder 10 is connected to the push rod 9. The bottom end surface of the push rod 9 is higher than the upper end surface of the cutting table 5. Among them, the push rod cylinder 10 is a rodless cylinder, which can be directly installed under the push rod 9, so that the push rod can move along the second slide rail 20. When the cut cover plate is removed by the material moving device 8, the waste left by the cutting can be pushed away by the push rod 9. Specifically, since the push rod 9 is located on the cutting table 5, when the push rod cylinder 10 pushes the push rod 9 to move, the waste on the cutting table 5 is pushed to one side by the push rod 9 and will not continue to stay on the cutting table 5, thereby facilitating the cutting of the next cover plate.

[0025] The automatic cutting and gluing mechanism for the cover of the roll paper packaging machine also includes a storage box 50, which is located below the cutting table 5 and corresponds to the push rod 9, that is, the waste pushed to one side by the push rod 9 falls into the storage box 50; wherein, the storage box 50 can be set in the form of a drawer to facilitate regular cleaning of the waste in the storage box 50.

[0026] The above are only preferred implementations of the present invention. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
