[0026] Please refer to Figure 1 In one embodiment, a multi-track paper tube forming machine 100 is provided, which is mainly used to achieve synchronous production of multiple paper tubes and improve the production efficiency of paper tubes.

[0027] The multi-track paper tube forming machine 100 includes an unwinding module 10, a gluing module 20 and a forming module 30 which are sequentially arranged, wherein the sequential arrangement is based on the conveying direction of the paper tape. The unwinding module 10 is used to synchronously provide multiple paper tapes to the gluing module 20, that is, the unwinding module 10 is the feeding part, the paper roll can be installed and placed in the unwinding module 10, and the unwinding module 10 synchronously provides multiple paper tapes at one time when feeding the gluing module 20, so that the synchronous forming of multiple paper tubes can be realized in the multi-track paper tube forming machine 100.

[0028] Among them, the way in which the unwinding module 10 provides multiple paper tapes can be: multiple paper rolls are placed in the unwinding module 10, so that the gluing module 20 is fed respectively through the multiple paper rolls, thereby providing multiple paper tapes; or, a slitting mechanism is provided in the unwinding module 10, and the paper tape provided by one paper roll can be slit into multiple paper tapes through the slitting mechanism, thereby providing multiple paper tapes.

[0029] Please refer to Figure 1 and Figure 4 , the gluing module 20 is provided with a plurality of paper tape channels 21, and each of the paper tape channels 21 is provided with a glue gun 22, and the glue gun 22 is used to spray glue on the overlap of the paper tape. That is to say, the gluing module 20 is provided with a plurality of paper tape channels 21 corresponding to the plurality of paper tapes, and the paper tapes can pass through the paper tape channels 21, and each of the paper tape channels 21 is provided with a glue gun 22, so that when the paper tape flows through the position of the glue gun 22, the glue gun 22 can spray glue on the paper tape, and the glue sprayed by the glue gun 22 is sprayed on the overlap of the edge of the paper tape, so as to facilitate the subsequent rolling of the paper tape into a paper tube.

[0030] In this embodiment, "plurality" or "plurality" refers to at least two (two).

[0031] The forming module 30 is provided with a plurality of forming cavities, which are arranged one by one in correspondence with the paper tape channels 21, and the forming cavities are used to roll the paper tape into a paper tube. In other words, the number and position of the forming cavities match the number and position of the paper tape channels 21, so that the forming module 30 can roll a plurality of paper tapes at the same time, thereby completing the synchronous rolling and forming of a plurality of paper tubes.

[0032] The multiple paper tapes provided by the unwinding module 10 first flow through the gluing module 20 for gluing, and then flow into the forming module 30, and the paper tapes are rolled and bent through the forming cavity in the forming module 30, so that the paper tapes are rolled and formed into paper tubes. Since glue is coated on the paper tapes, the overlaps on both sides of the paper tapes can be bonded by glue after rolling, so as to form a stable paper tube.

[0033] Specifically, in one embodiment, the unwinding module 10 is used to synchronously provide three paper tapes, the gluing module 20 is provided with three paper tape channels 21, and the forming module 30 is provided with three forming cavities.

[0034] Specifically, in one embodiment, each module in the multi-track forming paper tube machine 100 is arranged on a frame 101, and an adjustment margin is arranged between each module to meet the requirements of paper tape rolling with different widths. An electric control box 102 is arranged on the frame 101, and the electric control box 102 is used to control the operation of each module, and a foot cup 103 is also arranged at the bottom of the frame 101.

[0035] Please refer to Figure 2 and Figure 3 Preferably, in one embodiment, the unwinding module 10 includes a frame 11 and a plurality of unwinding units 12 installed on the frame 11, and the unwinding unit 12 is used to install and place a paper roll 200 (wherein the paper roll is wound by a paper tape), so that the paper tape can be gradually unwound and fed to the rear side through the unwinding unit 12. That is to say, in this embodiment, the unwinding module 10 provides a plurality of paper tapes in the following manner: a plurality of paper rolls 200 are placed in the unwinding module 10, so that the gluing module 20 is fed respectively by the plurality of paper rolls 200, so as to provide a plurality of paper tapes. More preferably, the paper roll installation positions of each of the unwinding units 12 are mutually staggered along the axial direction. That is to say, if Figure 2 As shown, along the axial direction, the paper roll installation positions of each unwinding unit 12 are spaced apart from each other, so that the unwound paper tapes are spaced apart by a certain distance along the width direction to avoid interference winding.

[0036] Specifically, in one embodiment, three unwinding units 12 are provided, and the three unwinding units 12 are arranged in sequence from top to bottom.

[0037] Preferably, in one embodiment, the unwinding unit 12 includes an unwinding portion 121, a connecting portion 122, and a tension control portion 123. The unwinding portion 121 is connected to the connecting portion 122, and the unwinding portion 121 is used to install and place the paper roll 200. The connecting portion 122 is connected to the frame 11. The tension control portion 123 is connected to the unwinding portion 121, and is used to control the unwinding tension of the unwinding portion 121.

[0038] Specifically, in one embodiment, the connecting portion 122 includes a fixing plate 1221, and the fixing plate 1221 is connected to the frame 11 by screws, so as to realize the installation of a single unwinding unit 12. The unwinding portion 121 includes an unwinding shaft 1211 and a clamping assembly arranged on the unwinding shaft 1211, and the unwinding shaft 1211 is connected to the fixing plate 1221 by a bearing seat. The clamping assembly is used to clamp the paper roll 200, and the clamping assembly includes a supporting bushing 1212, a clamping block 1213, and a locking nut 1214. The supporting bushing 1212 and the clamping block 1213 clamp the paper roll 200 by steps and inclined surfaces, and then the paper roll 200 is fixed by the locking nut 1214.

[0039] Considering the moment balance, a counterweight rod 1222 is provided at the rear end of the fixed plate 1221. Preferably, in one embodiment, the connecting portion 122 further comprises a counterweight rod 1222 and a seat bearing plate 1223, the seat bearing plate 1223 is relatively spaced from the fixed plate 1221, the counterweight rod 1222 passes through the fixed plate 1221 and is connected to the seat bearing plate 1223, and the unwinding shaft 1211 passes through the seat bearing plate 1223. In one embodiment, after fixing a single unwinding unit 12, by changing the length of the counterweight rod 1222 between the fixed plate 1221 and the seat bearing plate 1223, the position of the paper roll 200 is offset by 24 mm, thereby achieving the staggered installation of the three paper rolls 200. Specifically, in one embodiment, the tension control portion 123 can be installed on the seat bearing plate 1223.

[0040] Preferably, in one embodiment, the tension control part 123 includes a tension block 1231, a tension spring 1232, and a tension adjustment screw 1233. The tension block 1231 is provided with an arc-shaped groove, and a friction plate is bonded to the groove surface to contact the support bushing 1212. The flange of the tension adjustment screw 1233 at the rear end of the tension block 1231 presses against the tension spring 1232, and the tension spring 1232 is compressed or stretched by rotating the tension adjustment screw 1233, so as to increase or decrease the friction force of the tension block 1231, thereby realizing tension control.

[0041] Specifically, in one embodiment, the frame 11 is an aluminum profile frame.

[0042] The tension of the paper roll 200 is controlled by the design of the tension control part 123 and the counterweight rod 1222. This design ensures that the tension of the paper roll 200 is uniform during the unwinding process, thereby avoiding wrinkles and damage to the paper tape and improving the molding quality of the paper tube.

[0043] Please refer to Figure 4 Preferably, in one embodiment, the glue coating module 20 includes a glue coating bottom plate 23 and the glue gun 22, the paper tape channel 21 is opened on the glue coating bottom plate 23, and the paper tape channel 21 is extended along the length direction of the glue coating bottom plate 23. The glue gun 22 is connected to a glue box storing glue, and the gun head of the glue gun 22 is aligned with the edge of the paper tape channel 21, so that the glue sprayed from the glue gun 22 will be sprayed into the edge overlap of the paper tape.

[0044] The length direction of the rubber-coated bottom plate 23 is Figure 4 The width direction of the glue-coated bottom plate 23 is Figure 4 In the Y direction, the thickness direction of the glue-coated bottom plate 23 is Figure 4 Z direction shown.

[0045] The glue gun 22 is installed on the glue coating bottom plate 23 through a moving unit 24, and the moving unit 24 is used to drive the glue gun 22 to move so as to adjust the spraying position of the glue gun 22. That is, the moving unit 24 can drive the glue gun 22 to move, thereby changing the relative position between the glue gun 22 and the glue coating bottom plate 23, so as to adjust the spraying position of the glue gun 22 on the paper tape. Specifically, in one embodiment, the moving unit 24 can be a biaxial moving unit, and the moving unit 24 can drive the glue gun 22 to move in two directions (for example, the width direction and the thickness direction of the glue coating bottom plate 23). Through the setting of the moving unit 24, the fine adjustment of the glue coating position can be achieved, and it is also convenient to clean the gun head of the glue gun 22.

[0046] Specifically, in one embodiment, a groove may be further provided on the glue coating bottom plate 23 so that the moving unit 24 can drive the glue gun 22 to move.

[0047] Specifically, in one embodiment, the glue gun 23 is connected to the mobile unit 24 via a fixed base plate 25, the mobile unit 24 is connected to the glue coating base plate 23 via a support bar 26, and the support bar 26 is fixedly connected to the glue coating base plate 23 via screws.

[0048] Specifically, in one embodiment, the three equidistant paper tapes from the unwinding module 10 are transported to the gluing module 20 , and the gluing is completed through the gluing bottom plate 23 in cooperation with the glue gun 22 .

[0049] Preferably, in one embodiment, the glue coating bottom plate 23 is further provided with an inspection and cleaning hole 231, and the inspection and cleaning hole 231 penetrates the glue coating bottom plate 23 along the thickness direction of the glue coating bottom plate 23. The inspection and cleaning hole 231 is arranged to align with the gun head of the glue gun 22, and each glue gun 22 is correspondingly provided with one inspection and cleaning hole 231. It is understandable that when the glue gun 22 is working, glue is easily left on the gun head of the glue gun 22, thereby causing problems such as clogging of the gun head, affecting the normal glue coating of the glue gun 22, and therefore, the gun head of the glue gun 22 often needs to be cleaned and maintained. By setting the inspection and cleaning hole 231, when the gun head of the glue gun 22 needs to be cleaned and maintained, there is no need to disassemble the glue gun 22. The gun head of the glue gun 22 can be cleaned by passing the cleaning parts through the inspection and cleaning hole 231 from the back side of the glue coating base plate 23, thereby improving the cleaning and maintenance efficiency of the glue gun 22 and reducing the difficulty of cleaning and maintenance.

[0050] It is understandable that during the production process, the paper tape may be laterally offset due to various factors, resulting in a certain offset difference in the front and rear positions of the paper tape. Preferably, in one embodiment, the gluing module 20 also includes a gluing sliding unit 27, and the gluing base plate 23 is arranged on a slide of the gluing sliding unit 27, and the sliding direction of the slide is the width direction of the gluing base plate 23. The setting of the gluing sliding unit 27 can facilitate the adjustment of the lateral position of the gluing base plate 23 to better adapt to the offset of the paper tape. Specifically, the gluing sliding unit 27 can adopt any desired structure, such as an electric slide, a pneumatic slide, etc., and can even be manually driven, as long as it can drive the gluing base plate 23 to move laterally.

[0051] Specifically, in one embodiment, the glue sprayed by the glue gun 22 to the paper tape is hot melt glue. Specifically, in one embodiment, the glue gun 22 is a glue dispensing valve.

[0052] The gluing module 20 can accurately adjust the gluing and molding positions. This design not only ensures the uniformity and accuracy of gluing, but also ensures the stability of the paper tape during the molding process, thereby improving the consistency and quality of the product.

[0053] Preferably, in one embodiment, a paper guide roller may be further provided between the unwinding module 10 and the gluing module 20 .

[0054] Please refer to Figure 1and Figure 5 Specifically, in one embodiment, the paper tapes provided by the unwinding module 10 are all paper tapes with a narrow width, so that paper tubes with a smaller diameter can be produced. Preferably, in one embodiment, a pre-pressing module 40 is further provided between the gluing module 20 and the forming module 30, and the pre-pressing module 40 includes a pre-pressing bottom plate 41 and a pre-pressing block 42. A pre-pressing channel 411 is provided on the pre-pressing bottom plate 41, and the pre-pressing channel 411 is arranged one-to-one with the paper tape channel 21, and a pre-pressing block 42 is correspondingly arranged above each pre-pressing channel 411. That is to say, in this embodiment, the number and position of the pre-pressing channels 411 match the number and position of the paper tape channels 21, so that after each paper tape is glued in the gluing module 20, it can flow into the pre-pressing module 40 accordingly, and each paper tape is pre-pressed by the pre-pressing module 40 to facilitate the subsequent forming of the paper tube. It can be understood that the diameter of the paper tube formed in the multi-track paper tube forming machine 100 is smaller, and therefore the forming difficulty is greater. By setting the pre-pressing module 40, the paper tape can be pre-bent by the pre-pressing module 40, so that the paper tape enters the forming module 30 in a bent form, thereby reducing the difficulty of the forming module 30 in rolling the paper tape into the paper tube, and improving the stability of the multi-track paper tube forming machine 100 in forming the paper tube.

[0055] Specifically, in one embodiment, three pre-pressing channels 411 are provided, and three pre-pressing blocks 42 are provided correspondingly.

[0056] Specifically, in one embodiment, the pre-pressing channel 411 is an arc-shaped groove structure as a whole, and the bottom of the pre-pressing block 42 is an arc-shaped structure, which is conducive to bending the paper tape.

[0057] Preferably, in one embodiment, the pre-pressing block 42 is provided with a core shaft 43, and the core shaft 43 extends into the molding cavity of the molding module 30. Therefore, when the molding module 30 rolls the paper tape into shape, the core shaft 43 can correspondingly press against the inner side of the paper tape and support from the inner side of the paper tube, thereby ensuring that the paper tube is reliably rolled and formed, and ensuring that the formed paper tube will not have problems such as concave.

[0058] Specifically, in one embodiment, the pre-pressing block 42 is disposed on a pre-pressing bracket 44 .

[0059] Please refer to Figure 1Preferably, in one embodiment, the forming module 30 includes a forming plate group 31, a conveying and guiding module 32, and a hot pressing module 33. The cloth tape in the conveying and guiding module 32 passes through the forming plate group 31, and the cloth tape in the conveying and guiding module 32 is used to drive the paper tape to move and roll the paper tape into shape. The hot pressing module 33 can be flipped and arranged above the forming plate group 31 to heat the hot melt adhesive on the paper tape. That is to say, in this embodiment, the conveying and guiding module 32 provides power to drive the paper tape to move, thereby also pulling the paper tape on the front side, so as to realize the continuous movement of the paper tape (paper tube) in the entire multi-track paper tube forming machine 100, so that the paper roll 200 in the unwinding module 10 can be continuously unwound.

[0060] Please refer to Figure 6 and Figure 7 Specifically, in one embodiment, the conveying guide module 32 includes a driving unit (not shown), a driving wheel 321, a driven wheel 322, and a cloth belt 323. The driving unit is connected to the driving wheel 321 to drive the driving wheel 321 to rotate, and the driving unit can be a motor. The driven wheel 322 includes a first driven wheel 3221 and a second driven wheel 3222, and the first driven wheel 3221 and the second driven wheel 3222 are arranged in parallel and spaced apart.

[0061] The cloth belt 323 is provided with a plurality of (at least two) cloth belts, and each cloth belt 323 is sequentially wound around the driving wheel 321, the first driven wheel 3221, and the second driven wheel 3222. That is to say, after the cloth belt 323 is wound around the driving wheel 321, it will first be wound around the first driven wheel 3221, and then around the second driven wheel 3222, and then back to the driving wheel 321 via the second driven wheel 3222.

[0062] Preferably, in one embodiment, the cloth belt 323 passes through the pre-pressing module 40 .

[0063] Specifically, in one embodiment, three cloth belts 323 are provided, and the three cloth belts 323 are arranged parallel to each other and spaced apart along the axial direction of the driving wheel 321. The three cloth belts 323 are sequentially divided into a first cloth belt 3231, a second cloth belt 3232, and a third cloth belt 3233. Since three cloth belts 323 are provided, when the driving unit drives the driving wheel 321 to rotate, the three cloth belts 323 can be driven to operate synchronously.

[0064] The forming plate group 31 is located at the rear side of the first driven wheel 3221, wherein the rear side and the front side are based on the running direction of the cloth belt 323.

The first cloth belt 3231 passes through the first channel, the second cloth belt 3232 passes through the second channel, and the third cloth belt 3233 passes through the third channel. Specifically, at least part of the receiving channel is an arc-shaped cross-sectional structure, so that the receiving channel can bend the cloth belt 323 into an arc-shaped structure. In the process of the cloth belt 323 driving the paper belt to move, the cloth belt 323 will be bent into an arc-shaped structure, thereby bending the paper belt into a paper tube. That is, the cloth belt 323 is used to drive the paper belt to move and is also used to form the paper tube. The forming cavity for forming the paper tube is formed by bending and winding the cloth belt 323. After driving the paper belt into the accommodating channel, the cloth belt 323 is bent due to the guidance of the accommodating channel, so that the cloth belt 323 bends the paper belt and forms the paper belt into a paper tube.

[0065] More preferably, in one embodiment, a pressing plate may be provided on the forming plate group 31, and an arc groove may be provided on the lower side of the pressing plate to facilitate the forming of the paper tube.

[0066] It should be noted that in other embodiments, the number of the cloth belts 323 may be greater, for example, a fourth cloth belt, a fifth cloth belt, etc. may be provided, and accordingly, the number of the accommodating channels in the forming plate group 31 may also be changed accordingly. This embodiment is described by taking only three cloth belts 323 as an example.

[0067] The conveying guide module 32 is provided with a plurality of cloth belts 323, so that the plurality of paper tubes can be synchronously driven to move for forming, and the forming and conveying requirements of the plurality of paper tubes can be met. In addition, a plurality of accommodating channels are provided, so that the paper tubes can be guided and formed during the conveying process, and the paper tubes can be ensured not to deflect during the conveying process.

[0068] Preferably, in one embodiment, the conveying guide module 32 further includes an adjusting wheel group 325 and a tensioning wheel group 326. The adjusting wheel group 325 and the tensioning wheel group 326 are located at the rear side of the driving wheel 321 and at the front side of the first driven wheel 3221. The cloth belt 323 is wound out of the adjusting wheel group 325 and the tensioning wheel group 326 and then wound into the first driven wheel 3221. Through the arrangement of the adjusting wheel group 325 and the tensioning wheel group 326, each of the cloth belts 323 can be controlled and tensioned to ensure stable operation.

[0069] Preferably, in one embodiment, an angle wheel may be further provided near the driving wheel 321 .

[0070] Preferably, in one embodiment, the adjusting wheel group 325 includes a first adjusting wheel 3251, a second adjusting wheel 3252, a third adjusting wheel 3253, and a fourth adjusting wheel 3254, which are sequentially arranged in parallel and spaced apart. The tensioning wheel group 326 includes a first tensioning wheel 3261, a second tensioning wheel 3262, and a third tensioning wheel 3263, which are sequentially arranged in parallel and spaced apart. The first tensioning wheel 3261 is located below the first adjusting wheel 3251 and the second adjusting wheel 3252, and is located in the middle of the first adjusting wheel 3251 and the second adjusting wheel 3252. The second tensioning wheel 3262 is located below the second adjusting wheel 3252 and the third adjusting wheel 3253, and is located in the middle of the second adjusting wheel 3252 and the third adjusting wheel 3253. The third tensioning wheel 3263 is located below the third adjusting wheel 3253 and the fourth adjusting wheel 3254, and is located in the middle of the third adjusting wheel 3253 and the fourth adjusting wheel 3254. After the first cloth belt 3231 passes through the top of the first adjustment wheel 3251, the second adjustment wheel 3252, and the third adjustment wheel 3253, it goes around the bottom of the third tensioning wheel 3263, and then passes out from the top of the fourth adjustment wheel 3254. After the second cloth belt 3232 passes through the top of the first adjustment wheel 3251 and the second adjustment wheel 3252, it goes around the bottom of the second tensioning wheel 3262, and then passes out from the top of the third adjustment wheel 3253 and the fourth adjustment wheel 3254. After the third cloth belt 3233 passes through the top of the first adjustment wheel 3251, it goes around the bottom of the first tensioning wheel 3261, and then passes out from the top of the second adjustment wheel 3252, the third adjustment wheel 3253, and the fourth adjustment wheel 3254. Through this structure, the tensioning effect of the first cloth belt 3231, the second cloth belt 3232, and the third cloth belt 3233 is guaranteed. At the same time, the first cloth tape 3231, the second cloth tape 3232, and the third cloth tape 3233 can be made of the same length type, so that during maintenance, cloth tapes of the same length type can be used for maintenance and replacement.

[0071] Preferably, in one embodiment, it further includes a first tensioning control unit 3264, a second tensioning control unit 3265, and a third tensioning control unit 3266. The first tensioning control unit 3264 is connected to the first tensioning wheel 3261 to drive the first tensioning wheel 3261 to rise and fall. The second tensioning control unit 3265 is connected to the second tensioning wheel 3262 to drive the second tensioning wheel 3262 to rise and fall. The third tensioning control unit 3266 is connected to the third tensioning wheel 3263 to drive the third tensioning wheel 3263 to rise and fall. Through the setting of the tensioning control unit, the control of the tensioning wheel is more convenient and simple. And when the cloth belt 323 needs to be repaired and replaced, it is only necessary to drive the tensioning wheel to rise through the tensioning control unit to loosen the cloth belt 323, so as to facilitate the repair and replacement of the cloth belt 323. After the replacement is completed, it is only necessary to drive the tensioning wheel to descend through the tensioning control unit to tension the cloth belt 323. Specifically, the first tensioning control unit 3264, the second tensioning control unit 3265, and the third tensioning control unit 3266 can all adopt cylinders.

[0072] Preferably, in one embodiment, a deviation correction structure is provided in the conveying guide module 32, and the cloth belt 323 passes through the deviation correction structure. The deviation correction structure is provided with a cloth belt deviation adjustment roller group 327, and three cloth belt deviation adjustment roller groups 327 are provided, and each cloth belt 323 passes through a corresponding cloth belt deviation adjustment roller group 327. The cloth belt deviation adjustment roller group 327 can be used to adjust the lateral position of the corresponding cloth belt 323 to avoid the deflection of the cloth belt 323. Specifically, the cloth belt deviation adjustment roller group 327 is a manual deviation adjustment structure. The cloth belt deviation adjustment roller group 327 can be installed on the truss 328.

[0073] Please refer to Figure 8Specifically, in one embodiment, the deflection adjusting roller set 327 includes a deflection adjusting roller 3271, a star-shaped handle 3272, a positioning pin 3273, a bearing bushing 3274, and a threaded shaft 3275. The deflection adjusting roller 3271 can be mounted on the threaded shaft 3275, the star-shaped handle 3272 can be mounted on one end of the threaded shaft 3275, and the bearing bushing 3274 is connected to the deflection adjusting roller 3271 and mounted on the positioning pin 3273. By rotating the star-shaped handle 3272 and utilizing the threaded interaction between the bearing bushing 3274 and the threaded shaft 3275, the deflection adjusting roller 3271 and the bearing bushing 3274 can be moved axially along the positioning pin 3273 as a whole. The deviation adjusting roller 3271 is designed with an annular groove, the diameter of which is slightly smaller than the width of the cloth belt 323 and the groove should have a certain depth so that the cloth belt 323 can be well stuck and not fall off when passing through the deviation adjusting roller 3271. After adjustment, the deviation adjusting roller 3271 can be aligned with the accommodating channel in the forming plate group 31.

[0074] By setting the cloth tape deviation adjustment roller group 327, the position and angle of the cloth tape can be flexibly adjusted to ensure the precise alignment of each paper tape during the production process.

[0075] Please refer to Fig. 9 , the hot pressing module 33 is mainly used for heating and drying glue after the paper tube is formed. Specifically, in one embodiment, the hot pressing module 33 includes a forming layer 331 and a flipping mechanism 332. The forming layer 331 is provided with a heating rod 3311 and a temperature sensor 3312. The controller supplies power to the heating rod 3311 to increase the temperature. The sensor 3312 detects the temperature signal and feeds it back to the thermostat through the junction box 3313. Then the thermostat controls the controller to achieve real-time adjustment of the heating rod 3311, so as to accurately control the temperature of the heating rod 3311, thereby completing the heating and drying glue process control. The end of the flipping mechanism 332 is provided with a handle 3321, and the entire module can be flipped by applying force through the handle 3321. The end of the flipping mechanism 332 is also provided with a locking screw 3322, and the locking screw 3322 is used to connect and fix with other structures when it is put down, so as to stably press the hot pressing module 33. The heating rod 3311 and the temperature sensor 3312 can realize precise control of the glue drying process.

[0076] Please refer to Fig.10Preferably, in one embodiment, the forming module 30 further includes a cooling and shaping module 34, which is located above the forming plate group 31 and behind the hot pressing module 33, and is used to cool and shape the paper tube. That is to say, in this embodiment, after the cloth belt 323 drives the paper belt to move and form the paper tube, it will first pass through the hot pressing module 33 to heat the sol, and then pass through the cooling and shaping module 34 to cool and shape the glue, so as to ensure the forming effect of the paper tube.

[0077] Specifically, in one embodiment, the cooling and shaping module 34 includes a pressing clamp 341 and a shaping plate 342. The pressing clamp 341 is disposed on the truss 328. The shaping plate 342 is located above the shaping plate group 31, and a circular arc groove may be provided on the lower surface of the shaping plate 342. The pressing clamp 341 provides a certain pressure to the paper tube entering the channel by pressing the shaping plate 342, thereby further consolidating the paper tube shaping effect.

[0078] By setting the cooling and shaping module 34, the cooling and shaping effect of the paper tube after the glue is dried is ensured, thereby further consolidating the forming quality of the paper tube.

[0079] Preferably, in one embodiment, a pressing block may be provided at the rear side of the cooling and shaping module 34 to further consolidate the paper tube forming effect.

[0080] Please refer to Figure 1 Preferably, in one embodiment, the multi-track paper tube forming machine 100 further includes a paper tube gathering module 50 , and the paper tube gathering module 50 is located at the rear side of the forming module 30 .

[0081] Please refer to Figures 11 to 17 The paper tube gathering module 50 includes a gathering guide paper 51, and a guide channel 52 for paper tubes to flow through is provided in the gathering guide paper 51. Fig.13 The guide channel 52 includes a first guide channel 521 and a second guide channel 522 that are connected in sequence. Along the conveying direction of the paper tube, the first guide channel 521 is a structure with a gradually decreasing width. That is, at least one of the side walls 5211 of the first guide channel 521 is inclined inward, so that when multiple paper tubes flow through the first guide channel 521, the paper tubes located on the outside will be limited and guided by the side walls 5211 of the first guide channel 521, so that during the flow of the paper tubes, the paper tubes on the outside are guided to move inward, thereby reducing the spacing between the paper tubes.

[0082] It can be understood that the maximum width and the minimum width of the first guide channel 521 can be selected according to actual needs, and the maximum width of the first guide channel 521 only needs to meet the following requirements: not less than the overall width occupied by each paper tube before being gathered, ensuring that each paper tube can smoothly enter the first guide channel 521.

[0083] The width of the second guide channel 522 is not greater than the minimum width of the first guide channel 521, so that after the paper tube flows out of the first guide channel 521, the side wall of the second guide channel 522 can continue to limit the outer paper tube, ensuring that the outer paper tube will not spread outward. Specifically, the overall width of the second guide channel 522 can be the same as the minimum width of the first guide channel 521, or a part of the second guide channel 522 can also be set to a gradually narrowing width structure.

[0084] Specifically, in one embodiment, the side walls 5211 on both sides of the first guide channel 521 are inclined inward, so as to achieve position limiting and guiding of the paper tubes located on both sides.

[0085] Specifically, in one embodiment, there are three paper tubes that need to flow through the guide channel 52, and the three paper tubes are spaced apart from each other. The maximum width of the first guide channel 521 is not less than the overall width of the three paper tubes spaced apart from each other, and the minimum width of the first guide channel 521 is not greater than the overall width of the three paper tubes spaced apart from each other. Therefore, after the three paper tubes flow through the first guide channel 521, the outermost paper tubes will be guided inward, thereby reducing the spacing between the paper tubes.

[0086] Preferably, in one embodiment, the second guide channel 522 includes a connecting channel 5221 and a forming channel 5222, one end of the connecting channel 5221 is connected to the first guide channel 521, and the forming channel 5222 is connected to the other end of the connecting channel 5221. That is, when the paper tube flows through the guide channel 52, it flows through the first guide channel 521, the connecting channel 5221, and the forming channel 5222 in sequence. Wherein, along the width direction of the forming channel 5222, the bottom wall 52221 of the forming channel 5222 is divided into a plurality of bottom wall units, and at least one of the bottom wall units is a sunken structure. Wherein the sunken structure refers to that the height of the bottom wall unit is lower than the height of the other bottom wall units. That is to say, among the bottom wall units in the forming channel 5222, at least one bottom wall unit has a height lower than that of the other bottom wall units, so that the height of the paper tube flowing through the bottom wall unit can be guided to decrease, forming a height difference between the paper tubes, allowing some paper tubes to be located on the relatively upper side and some paper tubes to be located on the relatively lower side, thereby completing the change of the paper tube height.

[0087] Preferably, in one embodiment, along the width direction of the forming channel 5222, the bottom wall 52221 of the forming channel 5222 is divided into a central bottom wall unit 522211 and side bottom wall units 522212 located on both sides of the central bottom wall unit 522211. Thus, when three paper tubes flow through the forming channel 5222, the paper tube in the center can descend, so that a height difference is formed between the paper tube in the center and the paper tubes on both sides. When the three paper tubes flow out of the forming channel 5222, an inverted "pin" - shaped paper tube group can be formed as a whole.

[0088] Preferably, the central bottom wall unit 522211 includes an inclined bottom wall 5222111 close to one side of the connecting channel 5221 and a parallel bottom wall 5222112 far from one side of the connecting channel 5221. Along the conveying direction of the paper tube, the height of the inclined bottom wall 5222111 gradually decreases. The parallel bottom wall 5222112 is connected to the lowermost end of the inclined bottom wall 5222111. That is to say, the side of the central bottom wall unit 5222111 close to the connecting channel 5221 is a gradually downward - inclined structure (i.e., the inclined bottom wall 5222111), so that the paper tube in the center can be gradually guided to descend. During the descending process, there is no convex step structure on the central bottom wall unit 5222111, so that the paper tube is not easily damaged.

[0089] Preferably, in one embodiment, along the conveying direction of the paper tube, the head end of the forming channel 5222 is a width - tapering structure. Wherein, the head end of the forming channel 5222 refers to the part of the forming channel 5222 relatively close to the connecting channel 5221. It can be understood that since the paper tube on the central bottom wall unit 522211 will descend, a certain space will be vacated. By setting the head end of the forming channel 5222 as a width - tapering structure, during the flow of the upper paper tubes, the upper paper tubes will be guided to move inward, thereby reducing the spacing distance between the upper paper tubes.

[0090] Specifically, in one embodiment, the side walls 52222 on both sides of the head end of the forming channel 5222 are both inclined inward, so as to realize the limiting and guiding of the paper tubes on both sides.

[0091] Preferably, in one embodiment, along the conveying direction of the paper tube, at least a part of the bottom wall 5212 of the first guiding channel 521 is a structure with gradually increasing height. That is, at least a part of the bottom wall 5212 in the first guiding channel 521 can lift the height of the paper tube, so as to facilitate the docking of the paper tube gathering module 50 with the front and rear devices. Specifically, in one embodiment, a raised bottom wall 52121 is provided in the bottom wall 5212 of the first guiding channel 521, and the raised bottom wall 52121 is a gradually upward inclined bottom wall.

[0092] Preferably, in one embodiment, the paper tube gathering module 50 further includes a paper tube connecting glue gun 53, and the gun head 531 of the paper tube connecting glue gun 53 extends into the second guiding channel 522 to apply glue to the paper tubes in the second guiding channel 522. By applying glue to the paper tubes through the paper tube connecting glue gun 53, the paper tubes can be firmly connected. The paper tube connecting glue gun 53 can be connected to structures such as a glue tank for storing glue, which is well known in the art and will not be elaborated here.

[0093] Specifically, in one embodiment, the gun head 531 of the paper tube connecting glue gun 53 extends into the central area of the forming channel 5222, so as to be able to apply glue to the paper tube located in the center, bond three paper tubes, and enable the three paper tubes to stably form an inverted "pin" - shaped paper tube group. And due to the extension of the gun head 531 of the paper tube connecting glue gun 53, it can also have a certain pressing - down effect to ensure that the central paper tube can move downward.

[0094] Preferably, in one embodiment, the gathering guide cardboard 51 includes a bottom plate 511 and a cover plate 512 covering the bottom plate 511, the guiding channel 52 is opened on the bottom plate 511, and a glue gun hole 5121 for avoiding the paper tube connecting glue gun 53 is provided on the cover plate 512. Through the setting of the cover plate 512, the upper side of the paper tube can be limited. To prevent the paper tube from bouncing upward.

[0095] Specifically, in one embodiment, the cover plate 512 is an acrylic cover plate.

[0096] Preferably, in one embodiment, the paper tube gathering module 50 further includes a gathering sliding unit, and the gathering paper guide 51 is arranged on a slide of the gathering sliding unit, and the sliding direction of the slide is the width direction of the gathering paper guide 51. The arrangement of the gathering sliding unit can facilitate the adjustment of the lateral position of the gathering paper guide 51 to better adapt to the deviation of the paper tube (paper tape). Specifically, the gathering sliding unit can adopt any desired structure, such as an electric slide, a pneumatic slide, etc., and can even be manually driven, as long as it can drive the gathering paper guide 51 to move lateral.

[0097] Specifically, in one embodiment, the paper tube connecting glue gun 53 is a glue dispensing valve.

[0098] Preferably, in one embodiment, the paper tube connection glue gun 53 is installed on a movable platform 55, and the movable platform 55 can drive the paper tube connection glue gun 53 to move, so as to accurately adjust the glue dispensing position of the paper tube connection glue gun 53.

[0099] The gathering module 50 is used to achieve fine adjustment of the finished product character structure by merging three 24mm-spaced paper tubes, and can apply glue to the gaps between the three-track paper tubes to initially bond and fix the character-shaped paper tube group, so that it has a certain structural strength.

[0100] The multi-track paper tube forming machine 100 uses technologies such as multi-track synchronous unwinding, precise gluing, stable forming and efficient dry glue, which realizes the finished product character structure of three-way small paper tube merging, significantly improves the efficiency and quality of paper tube production, and meets market demand.

[0101] The above description is only an implementation mode of the present invention. It should be pointed out that, for ordinary technicians in this field, improvements can be made without departing from the creative concept of the present invention, but these all belong to the protection scope of the present invention.
