[0041] In order to make the skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by the skilled in the art without creative labor fall within the scope of protection of the present application.

[0044] In addition, the terms "first", "second", "third", etc. are used only for descriptive purposes and should not be construed as indicating or implying relative importance or an indicated number of technical features. Therefore, the features defined as "first", "second", etc. can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "a plurality of" or "several" is two or more, unless otherwise explicitly and specifically limited.

[0045] It should be understood that the structures, proportions, sizes, etc. shown in the drawings of the present application are only used to cooperate with the content disclosed in the description, to be understood and read by those skilled in the art, and do not have technical significance, and any modification of the structure, change of the proportion relationship or adjustment of the size, without affecting the effect and purpose that can be achieved by the present application, should still fall within the scope of the technical content disclosed by the present application.

[0046] The paper tube gathering structure provided by the present application comprises a paper guide plate, a guide channel for the flow of paper tubes is formed in the paper guide plate; along the conveying direction of the paper tube, the guide channel comprises a first channel and a second channel which are sequentially communicated; and along the conveying direction of the paper tube, the first channel is a width-tapered structure; and the width of the second channel is not greater than the minimum width of the first channel. The first channel in the paper tube gathering structure is a width-tapered structure, so that when the paper tube flows through the first channel, the side wall of the first channel can limit and guide the paper tube located on the side, thereby guiding the paper tube located on the side to gradually move to the inside during the flow process, reducing the spacing distance between the paper tubes, gathering the paper tubes, thereby meeting the subsequent production requirements and ensuring that the paper tubes can smoothly enter the large paper tube.

[0047] Please refer to Figures 1 to 8 In one embodiment, a paper tube gathering structure 100 is provided, which is mainly used to gather a plurality of paper tubes 200 to reduce the distance between the paper tubes 200, thereby meeting the production requirements of subsequent equipment.

[0048] The paper tube gathering structure 100 includes a guide plate 10, in which a guide channel 20 is formed for the paper tube 200 to flow through. Along the conveying direction of the paper tube 200 (e.g., as...) Figure 3 (As shown in the X direction), the guide channel 20 includes a first channel 21 and a second channel 22 connected in sequence. Along the conveying direction of the paper tube 200, the first channel 21 has a tapered width structure. That is, at least one of the sidewalls 211 of the first channel 21 is inclined inward, so that when multiple paper tubes 200 flow through the first channel 21, the paper tubes 200 located on the outer side are limited and guided by the sidewalls 211 of the first channel 21, thereby guiding the outer paper tubes 200 to move inward during the flow of the paper tubes 200, thereby reducing the spacing between the paper tubes 200.

[0049] It is understandable that the maximum and minimum widths of the first channel 21 can be selected according to actual needs. The maximum width of the first channel 21 only needs to meet the following requirements: it is not less than the overall width occupied by each paper tube 200 before they are gathered together, so as to ensure that each paper tube 200 can smoothly enter the first channel 21.

[0050] The width of the second channel 22 is no greater than the minimum width of the first channel 21. Therefore, after the paper tube 200 flows out of the first channel 21, the sidewall of the second channel 22 can continue to limit the outer portion of the paper tube 200, ensuring that the outer portion of the paper tube 200 does not further expand outwards. Specifically, the overall width of the second channel 22 can be the same as the minimum width of the first channel 21, or a portion of the second channel 22 can be configured as a tapered structure.

[0051] Specifically, in one embodiment, the sidewalls 211 on both sides of the first channel 21 are inclined inward, thereby enabling the paper tubes 200 located on both sides to be limited and guided.

[0052] Specifically, in one embodiment, three paper tubes 200 need to flow through the guide channel 20. These three paper tubes 200 are spaced apart from each other. The maximum width of the first channel 21 is not less than the overall width of the three spaced-apart paper tubes 200, and the minimum width of the first channel 21 is not greater than the overall width of the three spaced-apart paper tubes 200. Therefore, when the three paper tubes 200 flow through the first channel 21, the outermost paper tube 200 will be guided inward, thereby reducing the spacing between the paper tubes 200.

[0053] Preferably, in one embodiment, the second channel 22 includes a connecting channel 221 and a forming channel 222. One end of the connecting channel 221 is communicated with the first channel 21, and the forming channel 222 is communicated with the other end of the connecting channel 221. That is to say, when the paper tube 200 flows through the guiding channel 20, it sequentially flows through the first channel 21, the connecting channel 221, and the forming channel 222. Among them, along the width direction of the forming channel 222, the bottom wall 2221 of the forming channel 222 is divided into multiple bottom wall units, and at least one of the bottom wall units is a sunken structure. The sunken structure means that the height of the bottom wall unit is lower than the height of other bottom wall units. That is to say, among the bottom wall units in the forming channel 222, at least one of the bottom wall units has a height lower than that of other bottom wall units, so as to guide the height of the paper tube 200 flowing through the bottom wall unit to decrease, so as to form a height difference between the paper tubes 200, so that some of the paper tubes 200 are located on the relatively upper side and some of the paper tubes 200 are located on the relatively lower side, thereby completing the change of the height of the paper tube 200.

[0054] Preferably, in one embodiment, along the width direction of the forming channel 222, the bottom wall 2221 of the forming channel 222 is divided into a central bottom wall unit 22211 and side bottom wall units 22212 located on both sides of the central bottom wall unit 22211. Thus, when the three paper tubes 200 flow through the forming channel 222, the paper tube 200 in the center can descend, so that a height difference is formed between the central paper tube 200 and the paper tubes 200 on both sides. When the three paper tubes 200 flow out of the forming channel 222, an inverted "pin" - shaped paper tube group can be formed as a whole.

[0055] Preferably, the central bottom wall unit 22211 includes an inclined bottom wall 222111 close to one side of the connecting channel 221 and a parallel bottom wall 222112 far from one side of the connecting channel 221. Along the conveying direction of the paper tube 200, the height of the inclined bottom wall 222111 gradually decreases. The parallel bottom wall 222112 is connected to the lowest end of the inclined bottom wall 222111. That is to say, the side of the central bottom wall unit 22211 close to the connecting channel 221 is a gradually downward - inclined structure (i.e., the inclined bottom wall 222111), so as to gradually guide the paper tube 200 in the center to descend. During the descending process, there is no protruding step structure in the central bottom wall unit 22211, so it is not easy to damage the paper tube 200.

[0056] Preferably, in one embodiment, along the conveying direction of the paper tube 200, the head end of the forming channel 222 is a width-tapering structure. Here, the head end of the forming channel 222 refers to the part of the forming channel 222 relatively closer to the connecting channel 221. It can be understood that since the paper tube 200 located on the central bottom wall unit 22211 will descend, a certain space will be vacated. By setting the head end of the forming channel 222 as a width-tapering structure, during the flow of the upper paper tube 200, the upper paper tube 200 will be guided to move inward, thereby reducing the spacing distance between the upper paper tubes 200.

[0057] Specifically, in one embodiment, the side walls 2222 on both sides of the head end of the forming channel 222 are both inclined inward, so as to limit and guide the paper tubes 200 located on both sides.

[0058] Preferably, in one embodiment, along the conveying direction of the paper tube 200, at least a part of the bottom wall 212 of the first channel 21 is a height-increasing structure. That is, at least a part of the bottom wall 212 in the first channel 21 can lift the height of the paper tube 200, so as to facilitate the docking of the paper tube gathering structure 100 with the front and rear devices. Specifically, in one embodiment, a raised bottom wall 2121 is provided in the bottom wall 212 of the first channel 21, and the raised bottom wall 2121 is a gradually upward inclined bottom wall.

[0059] Preferably, in one embodiment, the paper tube gathering structure 100 further includes a glue gun 30, and the gun head 31 of the glue gun 30 extends into the second channel 22 to coat glue on the paper tubes 200 in the second channel 22. By coating glue on the paper tubes 200 through the glue gun 30, the paper tubes 200 can be firmly connected. The glue gun 30 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.

[0060] Specifically, in one embodiment, the gun head 31 of the glue gun 30 extends into the central area of the forming channel 222, so as to coat glue on the central paper tube 200, bond the three paper tubes 200, and enable the three paper tubes 200 to stably form an inverted "pin" - shaped paper tube group. And due to the extension of the gun head 31 of the glue gun 30, it can also have a certain pressing-down effect to ensure that the central paper tube 200 can move downward.

[0061] Preferably, in an embodiment, the paper guiding plate 10 comprises a bottom plate 11 and a cover plate 12 arranged on the bottom plate 11, the guiding channel 20 is arranged on the bottom plate 11, and the cover plate 12 is provided with a glue gun hole 121 for avoiding the glue gun 30. The upper side of the paper tube 200 can be limited by the cover plate 12, so as to avoid the paper tube 200 from being bounced upward.

[0062] It can be understood that, in the production process, the paper tube 200 (paper tape) may be deviated in the transverse direction due to various factors, so as to cause a certain deviation of the front and back positions of the paper tube 200 (paper tape). Preferably, in an embodiment, the paper tube gathering structure 100 further comprises a sliding unit, the paper guiding plate 10 is arranged on a sliding table of the sliding unit, and the slidable direction of the sliding table is the width direction of the paper guiding plate 10. The sliding unit can be arranged to facilitate the adjustment of the transverse position of the paper guiding plate 10, so as to better adapt to the deviation of the paper tube 200 (paper tape). Specifically, the sliding unit can adopt any required structure, for example, an electric sliding table, a pneumatic sliding table, etc., or even a manually driven mode, as long as it can drive the paper guiding plate 10 to move in the transverse direction.

[0063] Please refer to Figure 9 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, a forming mechanism 330 and the paper tube gathering structure 100. The glue applying mechanism 320 is located at the rear side of the raw material placing position 310, the forming mechanism 330 is located at the rear side of the glue applying mechanism 320, and the paper tube gathering structure 100 is located at the rear side of the forming mechanism 330. The raw material placing position 310 is used to place a paper roll wound by a paper tape. The paper tape in the paper roll flows into the glue applying mechanism 320 to be coated with glue, and then flows into a cavity in the forming mechanism 330 to be formed into a paper tube. Specifically, in an embodiment, the glue applying mechanism 320 applies hot melt glue to the edge of the paper tape, and the forming mechanism 330 is provided with a hot-press forming block.

[0064] Specifically, a tape conveying mechanism is provided in the shaping mechanism 330. The tape conveying mechanism includes a driving wheel, a driven wheel, and a tape wound between the driving wheel and the driven wheel. The driving wheel is connected to a motor, so that the motor drives the driving wheel to rotate, and then drives the tape to run. Through the running of the tape, the paper tube 200 and the paper tape are continuously moved, and the tape is used for the winding and shaping of the paper tape to wind the paper tape into the paper tube 200.

[0065] Preferably, in one embodiment, a paper tube forming unit is further provided. The paper tube forming unit includes the paper tube forming machine 300 and a large paper tube forming machine 400. The shaping mechanism of the large paper tube forming machine 400 is located behind the paper tube gathering structure 100. After the paper tube 200 flows out of the paper tube gathering structure 100, it directly flows into the shaping mechanism of the large paper tube forming machine 400, so as to directly feed the "pin" - shaped small paper tube group into the large paper tube.

[0066] The above are only the embodiments of the present invention. It should be noted here that for those of ordinary skill in the art, without departing from the creative concept of the present invention, improvements can still be made, but these all fall within the protection scope of the present invention.
