[0032] A paper bag tube forming device according to an embodiment of the utility model is described below in conjunction with the accompanying drawings.

[0033] Reference Figure 1 , Figure 2 and Figure 3 A paper bag tube forming device according to an embodiment of the utility model includes a frame 100, a traction mechanism 120, an upper guide mechanism, a limit frame 160 and an inner guide mechanism.

[0034] Regarding the frame 100 , a support platform 110 is disposed on the frame 100 , and the support platform 110 is used to support the movement of the paperboard strip, thereby making the conveying movement of the paperboard strip more stable.

[0035] The traction mechanism 120 is located at the discharge end of the support platform 110 and is used to traction and convey the paperboard strip to move, thereby realizing the automatic conveyance of the paperboard strip by the paper bag tube forming device and improving efficiency.

[0036] Specifically, the traction mechanism 120 includes an upper traction roller and a lower traction roller rotatably arranged on the frame 100 and a first motor driving the upper traction roller or the lower traction roller to rotate. The upper traction roller and the lower traction roller clamp and traction and convey the paperboard strip.

[0037] As for the upper guide mechanism, the upper guide mechanism includes two upper guide assemblies 130, and the two upper guide assemblies 130 respectively guide the bottom surfaces of both sides of the paperboard strip to fold upward. The upper guide assembly 130 includes a first frame 140 installed on the frame 100, and a first wheel 150 rotatably arranged on the first frame 140. The first wheel 150 abuts against the bottom surface of the paperboard strip for guidance.

[0038] It can be understood that when the cardboard strip moves forward, the first wheel 150 abuts against the bottom surface of the cardboard strip and guides the side of the cardboard strip to bend upward. At the same time, the first wheel 150 can roll on the cardboard strip, thereby reducing the friction resistance when the first wheel 150 abuts against the cardboard strip. On the one hand, it reduces the risk of the first wheel 150 scratching the cardboard strip, and on the other hand, it makes the transportation of the cardboard strip more labor-saving.

[0039] In some specific embodiments, the first frame 140 includes a first vertical rod 240, a connecting block 250 and a first cross rod 260. The first vertical rod 240 is fixed on the frame 100. The connecting block 250 has a first through hole extending up and down and a second through hole extending horizontally. The first through hole is used to install the first vertical rod 240, and the second through hole is used to install the first cross rod 260. The first wheel 150 is rotatably arranged at one end of the first cross rod 260, so as to facilitate the first vertical rod 240, the connecting block 250 and the first cross rod 260 to cooperate and support the rotation of the first wheel 150.

[0040] Furthermore, the first vertical rod 240 is slidably connected to the first through hole up and down, and the connecting block 250 is threadedly connected with the first bolt 270, and the first bolt 270 abuts against the first vertical rod 240 to fix the first vertical rod 240, thereby making it convenient to adjust the height of the connecting block 250 by loosening and tightening the first bolt 270, and further, to facilitate adjusting the height of the first wheel 150.

[0041] In some specific embodiments, the first cross bar 260 is horizontally slidably connected to the second through hole, the connecting block 250 is threadedly connected with the second bolt 280, and the second bolt 280 abuts against the first cross bar 260 to fix the first cross bar 260, thereby facilitating the adjustment of the horizontal position of the first cross bar 260 by loosening and tightening the second bolt 280, and further facilitating the adjustment of the horizontal position of the first wheel 150.

[0042] In some specific embodiments, the rotation direction of the first wheel 150 is arranged to be inclined upward along the conveying direction of the paperboard strip, so that the first wheel 150 guides and bends the paperboard strip upward in the inclined upward direction when rotating.

[0043] The limiting frame 160 is located between the two upper guide assemblies 130. The limiting frame 160 includes a frame body 170 connected to the frame 100 and two limiting arms 180 located at the bottom of the frame body 170. One end of the two limiting arms 180 is extended along the moving direction of the paperboard strip, and the two limiting arms 180 are respectively in contact with the top surfaces on both sides of the paperboard strip for limiting.

[0044] It is understandable that when the paperboard strip passes between the upper guide assembly 130 and the limiting arm 180, the upper guide assembly 130 can guide the side of the paperboard strip upward to bend, and at the same time, the limiting arm 180 can limit the paperboard strip above the paperboard strip to limit the upward shaking of the paper strip board, thereby ensuring the paper tube forming effect.

[0045] In some specific embodiments, a support roller 220 is rotatably provided at the bottom of the limit frame 160. The support roller 220 is located on the side of the limit arm 180 away from the discharge end of the support platform 110. The bottom of the support roller 220 is in contact with the top surface of the paperboard strip for support, so that the paperboard strip can pass through the support roller 220 and the limit arm 180 in sequence during transportation. When the paperboard strip passes through the support roller 220, the support roller 220 can roll with the paperboard strip, thereby preventing the paperboard strip from being directly rubbed and collided with the sharp corners of the limit arm 180 and damaged.

[0046] Furthermore, the end of the support roller 220 has an arc surface, which abuts against the top surface of the paperboard strip for support, thereby reducing the collision between the sharp corner of the support roller 220 and the paperboard strip, thereby reducing the risk of damaging the paperboard strip.

[0047] As for the inner guide mechanism, the inner guide mechanism is located on one side of the upper guide mechanism close to the discharge end of the support platform 110, and the inner guide mechanism includes at least two inner guide components 190, and the at least two inner guide components 190 respectively guide the two sides of the paperboard strip inward after being folded upward, and the inner guide component 190 includes a second frame 200 installed on the frame 100, and a second wheel 210 rotatably set on the second frame 200, and the second wheel 210 abuts against the bottom surface of the paperboard strip for guidance.

[0048] It is understandable that when the cardboard strip with both sides bent upwards continues to move through the inner guide mechanism, the two second wheels 210 guide and bend both sides of the cardboard strip inwards respectively, so that the edges of both sides of the cardboard strip overlap each other, thereby forming a cylindrical shape of the cardboard strip.

[0049] In some specific embodiments, two inner guide assemblies 190 are arranged on the same side of the paperboard strip. The two inner guide assemblies 190 on the same side of the paperboard strip are arranged in sequence along the conveying direction of the paperboard strip, so that the inner guide mechanism has a better shaping effect on guiding the paperboard strip to bend inward.

[0050] In some specific embodiments, a pressing roller 290 is further provided on the frame 100. The pressing roller 290 is located on one side of the inner guide mechanism close to the discharge end of the support platform 110. The bottom of the pressing roller 290 is used to abut against one side edge of the cardboard strip, and the top of the pressing roller 290 is used to abut against the other side edge of the cardboard strip. Thus, the pressing roller 290 can guide the two side edges of the cardboard strip to be arranged up and down, thereby facilitating the two side edges of the cardboard strip to fit together up and down.

[0051] In some specific embodiments, the frame 100 is further provided with a flattening roller 300, which is located on the side of the edge pressing roller 290 close to the discharge end of the support platform 110. The flattening roller 300 cooperates with the support platform 110 to flatten the paperboard strip after tube making, so that the flattening roller 300 can flatten the cylindrical paperboard strip, thereby facilitating subsequent transportation.
