[0042] Please refer to Figures 1 to 4 In one embodiment, a gluing structure 100 is provided to solve the problem that the existing gluing mechanism can only be used for single paper tube production and cannot meet the production needs of multiple paper tubes (small paper tubes are additionally arranged inside large paper tubes).

[0043] The glue applying structure 100 comprises a paper guide plate 10, a first glue gun 20, a second glue gun 30 and a connecting plate 40. The paper guide plate 10 is provided with a paper guide channel 11 for accommodating a paper strip 200, which can flow through the paper guide plate 10 via the paper guide channel 11 during production. The gun head 21 of the first glue gun 20 is arranged in alignment with the edge of the paper guide channel 11, so that the glue sprayed from the gun head 21 of the first glue gun 20 is applied to the edge 210 of the paper strip 200 (i.e. the overlap part of the paper strip) during production. The glue sprayed from the first glue gun 20 is mainly used for the subsequent roll forming and bonding of the paper strip 200. The gun head 31 of the second glue gun 30 is arranged in alignment with the central region of the paper guide channel 11, so that the glue sprayed from the gun head 31 of the second glue gun 30 is applied to the central region 220 of the paper strip 200 during production. The glue sprayed from the second glue gun 30 is mainly used for the subsequent bonding of the paper strip 200 and the small paper tube inside.

[0044] That is, the glue applying structure 100 provided in this embodiment is mainly used for applying glue to the outer large paper tube in the multiple paper tubes. When applying glue to the paper strip before being formed into a large paper tube, the paper strip 200 is applied with glue at two positions by the first glue gun 20 and the second glue gun 30, one position for the roll forming of the paper strip 200 and the other position for the bonding of the paper strip 200 and the small paper tube inside.

[0045] The paper strip 200 is mainly divided into the central region 220 in the center and the edges 210 on both sides of the central region 220 along the width direction. The first glue gun 20 can only spray glue on one of the edges 210. The specific spraying position of the second glue gun 30 on the central region 220 can be selected according to actual production requirements (which can be selected according to the position or number of the small paper tube to be bonded).

[0046] The connecting plate 40 is connected to the side edge 12 of the paper guide plate 10, and the first glue gun 20 and / or the second glue gun 30 are connected to the paper guide plate 10 via the connecting plate 40. That is, at least one of the first glue gun 20 and the second glue gun 30 is directly connected to the paper guide plate 10 via the connecting plate 40 and is directly mounted on the paper guide plate 10. Since the connecting plate 40 is connected to the side edge 12 of the paper guide plate 10, it will not block the paper strip 200 and will not affect the normal conveying of the paper strip 200.

[0047] It can be understood that, in the production process, the paper tape 200 can be offset in the transverse direction due to various factors, resulting in a certain offset difference in the front and back positions of the paper tape 200 (paper tube). In order to compensate for the offset difference in the front and back positions, the paper guide plate 10 is usually moved in the transverse direction to adjust the position of the paper tape 200 in the paper guide plate 10. After adjusting the position of the paper guide plate 10, the positions of the first glue gun 20 and the second glue gun 30 also need to be adjusted synchronously to ensure the accuracy of the glue spraying position. By connecting the first glue gun 20 and / or the second glue gun 30 with the paper guide plate 10 through the connecting plate 40, the first glue gun 20 and / or the second glue gun 30 are moved synchronously when the position of the paper guide plate 10 is adjusted, so that the positions of the first glue gun 20 and / or the second glue gun 30 do not need to be adjusted separately, and the first glue gun 20 and / or the second glue gun 30 do not need to be aligned with the paper guide plate 10 again, thereby reducing the difficulty of adjustment. In the maintenance process, the first glue gun 20 and / or the second glue gun 30 are connected with the paper guide plate 10 as a whole, thereby reducing the difficulty of maintenance and installation.

[0048] It should be noted that when the first glue gun 20 and the second glue gun 30 are connected with the paper guide plate 10: the first glue gun 20 and the second glue gun 30 can be connected on the same connecting plate 40; or the first glue gun 20 and the second glue gun 30 can be connected with the paper guide plate 10 through different connecting plates 40.

[0049] Preferably, in an embodiment, the paper guide channel 11 extends along the length direction of the paper guide plate 10. The glue applying structure 100 further comprises a sliding unit 50, the paper guide plate 10 is arranged on a sliding table 51 of the sliding unit 50, and the slidable direction of the sliding table 51 is along the width direction of the paper guide plate 10. The sliding unit 50 can facilitate the adjustment of the position of the paper guide plate 10. Specifically, the sliding unit 50 can adopt any required structure, such as an electric sliding table, a pneumatic sliding table, etc., or even a manually driven mode, as long as it can drive the paper guide plate 10 to move in the transverse direction.

[0050] The length direction of the paper guide plate 10 is the X direction shown in the figure, the width direction of the paper guide plate 10 is the Y direction shown in the figure, and the thickness direction of the paper guide plate 10 is the Z direction shown in the figure. Figure 2 Figure 2 Figure 2

[0051] ​​​Preferably, in an embodiment, the second glue gun 30 is connected with the paper guide plate 10 through the connecting plate 40. That is, in this embodiment, at least the second glue gun 30 is mounted on the paper guide plate 10 through the connecting plate 40.

[0052] Preferably, in an embodiment, the second glue gun 30 is rotatably connected with the connecting plate 40, and the rotation axis of the second glue gun 30 is parallel to the width direction of the paper guide plate 10. By setting the second glue gun 30 in a rotatable structure, the position of the second glue gun 30 can be adjusted when the equipment is stopped, and the second glue gun 30 can also be conveniently maintained and cleaned. For example, when the equipment is stopped, the second glue gun 30 can be rotated to rotate the gun head 31 of the second glue gun 30 to a standby position, so as to avoid waste of glue, and also to avoid excessive glue being applied to the paper tape 200 when the equipment is stopped, which affects the stability of subsequent molding. Moreover, when being maintained, the gun head 31 can be cleaned and maintained only by rotating the second glue gun 30, which reduces the difficulty of maintenance.

[0053] Preferably, in an embodiment, a positioning structure 60 is arranged between the second glue gun 30 and the connecting plate 40. The positioning structure 60 comprises a positioning protrusion and a positioning hole 61 matched with the positioning protrusion. The positioning protrusion is arranged on one of the second glue gun 30 and the connecting plate 40, and the positioning hole 61 is arranged on the other one of the second glue gun 30 and the connecting plate 40. That is, when the positioning protrusion is arranged on the second glue gun 30, the positioning hole 61 is arranged on the connecting plate 40; when the positioning protrusion is arranged on the connecting plate 40, the positioning hole 61 is arranged on the second glue gun 30. The positioning hole 61 is arranged at least in two, and the two positioning holes 61 are arranged at intervals along the rotatable direction of the second glue gun 30. Thus, by rotating the second glue gun 30, the positioning protrusion is clamped into different positioning holes 61, so as to quickly adjust and position the position of the second glue gun 30. For example, when the second glue gun 30 is rotated to clamp the positioning protrusion into one positioning hole 61, the second glue gun 30 is located at a working position, so as to quickly adjust and position the working position; when the second glue gun 30 is rotated to clamp the positioning protrusion into another positioning hole 61, the second glue gun 30 is located at a standby position, so as to quickly adjust and position the standby position.

[0054] Preferably, in an embodiment, the second glue gun 30 is rotatably connected with the connecting plate 40 through a transition plate 70. The positioning hole 61 is arranged on the transition plate 70, and the positioning protrusion is arranged on the connecting plate 40.

[0055] Preferably, in an embodiment, the first glue gun 20 and the second glue gun 30 are connected to the paper guide plate 10 through the connecting plate 40 respectively. That is, in this embodiment, the first glue gun 20 and the second glue gun 30 are both connected to the paper guide plate 10.

[0056] Preferably, in an embodiment, the first glue gun 20 is a hot-melt glue gun, and the second glue gun 30 is a cold glue gun. That is, the glue stored in the glue tank connected to the first glue gun 20 is hot-melt glue, so that the glue sprayed through the first glue gun 20 is hot-melt glue; the glue stored in the glue tank connected to the second glue gun 30 is cold glue, so that the glue sprayed through the second glue gun 30 is cold glue.

[0057] Preferably, in an embodiment, the second glue gun 30 is located on the front side of the first glue gun 20. Wherein, the front side is referenced to the conveying direction of the paper tape 200. That is, when the paper tape 200 flows through the paper guide plate 10, the paper tape 200 will first pass through the position where the second glue gun 30 is located, and then pass through the position where the first glue gun 20 is located.

[0058] Please refer to Figure 5 . Meanwhile, in an embodiment, a paper tube forming machine 300 is also provided, which comprises a raw material placing position 310, a glue applying mechanism 320, and a forming mechanism 330. The raw material placing position 310 is used to place a paper roll wound by the paper tape 200. The glue applying mechanism 320 is located on the rear side of the raw material placing position 310, and is provided with the glue applying structure 100. The forming mechanism 330 is located on the rear side of the glue applying mechanism 320. The paper tape 200 in the paper roll first flows into the glue applying mechanism 320 for glue applying, and then flows into a cavity in the forming mechanism 330 for paper tube forming. Specifically, in an embodiment, the glue applying mechanism 320 applies hot-melt glue to the edge 210 of the paper tape 200, and the forming mechanism 330 is provided with a hot-press forming block.

[0059] Specifically, in an embodiment, the forming mechanism 330 is provided with a cloth tape conveying mechanism, which comprises a driving wheel, a driven wheel, and a cloth tape wound between the driving wheel and the driven wheel. The driving wheel is connected to a motor, so that the driving wheel is driven to rotate by the motor, thereby driving the cloth tape to move. Through the movement of the cloth tape, the paper tube (the paper tape 200) is continuously moved. And the cloth tape is used to roll the paper tape 200 into a paper tube.

[0060] Preferably, in an embodiment, the paper tube forming machine set further comprises a small paper tube forming machine 400 located in front of the paper tube forming machine 300, which is used to form 3 small paper tubes (compared with the paper tubes formed by the paper tube forming machine 300, the paper tubes formed by the small paper tube forming machine 400 are smaller in diameter). After the small paper tube forming machine 400 forms the small paper tubes, the small paper tubes are sent into the forming mechanism 330 and located inside the paper tubes formed by the paper belt 200, so that the finally formed paper tubes are multi-layer paper tube structures (i.e. structures in which a large paper tube contains multiple small paper tubes), thereby meeting the production and use requirements.

[0061] The small paper tube forming machine 400 can also comprise corresponding raw material placing positions, gluing mechanisms, forming mechanisms, thereby realizing automatic rolling and forming of the paper belt into the paper tube, which will not be described herein.

[0062] The above only describes the embodiments of the present application, and it should be pointed out that, for those skilled in the art, improvements can be made without departing from the inventive concept of the present application, but these all belong to the protection scope of the present application.
