[0015] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0016] like Figure 1~Figure 2 The system shown is an automatic system for making thin paper tubes, which includes a paper loading mechanism 2, a conveying mechanism, a gluing mechanism, a cutting mechanism, a forming mechanism, and an output mechanism 26 installed on a machine body 1.

[0017] At least two paper tray installation positions 301 are set in the paper feeding mechanism 2, on which the old paper tray 5 and the new paper tray 4 are respectively installed, and the old paper tape 82 and the new paper tape 81 on the old paper tray 5 and the new paper tray 4 can be overlapped. Its specific structure is: the paper feeding mechanism 2 is composed of a paper tray frame 3, an old paper tray 5, a new paper tray 4, and a plurality of front steering rollers 6. The old paper tray 5 and the new paper tray 4 are both installed on the rotatable paper tray frame 3. The old paper tape 82 is drawn out from the old paper tray 5 and then passes through the front steering roller 6 and enters between the two lower rollers 7, and passes through the lower roller 7 to enter the first steering roller 12 of the conveying mechanism. A knife anvil 9 is also provided below the lower roller 7. The lower roller 7 drives the paper tape 8 to be conveyed to the knife anvil 9. The knife anvil 9 is connected to a negative pressure device, and the paper tape 8 is adsorbed on the knife anvil 9. A cutter 11 is provided on one side of the knife anvil 9. The cutter 11 is opposite to the gap in the middle of the knife anvil 9, and a paper head collecting device 10 is provided on the rear side of the knife anvil 9.

[0018] When the paper tape 8 on the old paper tray 5 is about to run out, the new paper tray 4 is installed on the paper tray rack 3, and the new paper tape 81 is manually guided around the front steering roller 6 and then introduced between the lower rollers 7 to continue to be guided downward through the gap in the middle of the anvil 9 to be connected to the paper head collecting device 10. At this time, the new paper tape 81 and the old paper tape 82 will be superimposed on the upper part of the gap in the anvil 9, and the cutter 11 moves toward the gap in the anvil 9 to cut off the old paper tape 82. The cut new paper tape 81 and the old paper tape 82 are adsorbed on the anvil 9, and then the rear section of the new paper tape 81 and the front section of the old paper tape 82 are pasted together at the gap using paper tape. The rear section of the old paper tape 82 will stop due to loss of power, and the front section of the new paper tape 81 will be cut off and rolled away by the paper head collecting device 10.

[0019] In addition, the paper tray rack 3 itself can rotate, and the two paper tray mounting positions 301 on the paper tray rack 3 can be interchanged in upper and lower positions. In order to ensure the same structure after the interchange, the front steering roller 6 corresponding to each paper tray mounting position 301 is centrally symmetrically arranged. When the new paper tape 81 on the new paper tray 4 is nearly one-third remaining, the paper tray mounting rack rotates 180°, and the two paper tray mounting positions 301 are interchanged.

[0020] The paper tape 8 of the paper feeding mechanism 2 enters the cutting mechanism through the conveying mechanism and the gluing mechanism to be cut into segments. The paper segments form paper tubes 32 in the forming mechanism, and the output mechanism 26 takes the paper tubes 32 out of the forming mechanism and continues to output them forward.

[0021] The conveying mechanism is composed of a first steering roller 12, a paper-drawing roller 13, a second steering roller 15, and a paper-controlling roller 16. The paper-drawing roller 13 is driven to rotate by a power device. Multiple first steering rollers 12 and second steering rollers 15 are provided. The paper tape 8 passes through the first steering roller 12, the paper-drawing roller 13, the second steering roller 15, and the paper-controlling roller 16 in sequence, and then enters the gluing mechanism after passing through the paper-controlling roller 16, thereby realizing stable conveying and tension control of the paper tape 8.

[0022] The glue coating mechanism consists of a glue pool 17, a glue transport roller 18, and a glue coating roller 19. The glue pool 17 is provided with liquid glue. The glue transport roller 18 is located in the glue pool 17. The glue coating roller 19 is located above the glue transport roller 18 and in contact with the glue transport roller 18. The paper tape 8 is wrapped around the upper side of the glue coating roller 19. The glue transport roller 18 transports the liquid glue in the glue pool 17 to the glue coating roller 19, and the glue coating roller 19 coats the liquid glue on the paper tape 8.

[0023] The cutting mechanism is composed of a plurality of supporting rollers 20, a paper cutting roller 23 and a cutter 24. The paper tape 8 passing through the glue coating roller 19 enters the paper cutting roller 23 through the plurality of supporting rollers 20. The paper cutting roller 23 is a negative pressure roller. The paper cutting roller 23 is provided with cutting grooves 27 evenly distributed on the circumference. The cutter 24 is a rotating knife with multiple blades 28. The cutter 24 is located on the outer side of the paper cutting roller 23. The rotating blade 28 of the cutter 24 cuts the paper tape 8 into segments at the cutting groove 27 to achieve precise cutting.

[0024] The forming mechanism includes an active disk 25, which is located below the paper cutting roller 23. The active disk 25 is driven to rotate by a power device. One side of the active disk 25 is provided with forming rods 29 and pressing rods 30 evenly distributed in a circle. The forming rods 29 are located outside the pressing rods 30. The forming rods 29 correspond to the pressing rods 30 one by one and can be separated and pressed. The forming rods 29 are negative pressure rods and can rotate. The forming rods 29 are located on the lower side of the paper cutting roller 23 and are tangent to the paper cutting roller 23 at the closest point.

[0025] The paper strip 8 reaching the paper cutting roller 23 is cut into paper segments of required width by the cutter 24, and is adsorbed on the outer circular surface by the negative pressure system on the paper cutting roller 23 and rotates together with the paper cutting roller 23. When the cut paper segments rotate with the paper cutting roller 23 to the intersection with the active disk 25, the suction is disconnected and the paper segments are transferred to the forming rod 29. The adsorption system on the forming rod 29 adsorbs on the surface of the forming rod 29 and rotates with the forming rod 29, and is supported, guided and revolves with the active disk 25 through the smoothing component 31; the paper segments are pressed by the pressing rod 30 and rolled and pasted into paper tubes 32 under the action of the common rotation of the forming rod 29.

[0026] The output mechanism 26 is located below the active disk 25, and is composed of a tube taking device 33, a conveyor belt 34, an identification device 35, a rejection device 36, and a waste box 37. The tube taking device 33 takes the paper tube 32 rotating with the active disk 25 from the forming rod 29 and sends it to the conveyor belt 34. The conveyor belt 34 transports the paper tube 32 backward and the identification device 35 identifies whether it is qualified. Unqualified paper tubes 32 are rejected by the rejection device 36 located on one side of the conveyor belt 34 into the waste box 37, thereby realizing the output and quality screening of the paper tubes 32.

[0027] As a further improvement of the present invention, a paper pressing roller 14 is provided on the upper side of the paper tractor roller 13 to cooperate with it. The distance and contact pressure between the paper pressing roller 14 and the paper tractor roller 13 are adjustable. The paper pressing roller 14 presses the paper tape 8 against the paper tractor roller 13 to enhance the friction force of the paper tape 8 during transportation.

[0028] As a further improvement of the present invention, two paper pressing rollers 14 are provided and symmetrically arranged on both sides of the upper part of the paper pulling roller 13 to further improve the pressing effect.

[0029] As a further improvement of the present invention, a U-shaped groove is provided in the middle of the paper control roller 16, and the paper tape 8 passes through the U-shaped groove. The position of the U-shaped groove can be adjusted by changing the distance between the paper control roller 16 and the machine body 1, so as to facilitate the control of the position of the paper tape 8.

[0030] As a further improvement of the present invention, a tensioning roller 21 is provided between the supporting rollers 20. The tensioning roller 21 itself has a rotating power and is an elliptical structure. When the paper tape 8 is cut on the paper cutting roller 23, the tensioning roller 21 will tighten the paper tape 8 to ensure smooth cutting and effective cutting.

[0031] As a further improvement of the present invention, a heater 22 is further provided between the support roller 20 and the paper cutting roller 23, and the uncoated surface of the paper tape 8 is close to the upper side of the heater 22 to ensure the viscosity of the liquid glue and facilitate pasting and molding.

[0032] As a further improvement of the present invention, a smoothing component 31 is provided behind the tangent point between the paper cutting roller 23 and the forming rod 29. The lower side surface of the smoothing component 31 is an arc-shaped surface, which is close to the outer side of the forming rod 29. The paper segment is supported and guided by the arc-shaped surface to ensure that the paper tape 8 enters the forming link smoothly.
