[0043] Example

[0044] Please refer to Figures 1-5This utility model provides a vertical barrel mouth rolling machine, including a frame 1 that supports and connects various structures. A rolling structure 4 is provided on the top of the frame 1. A clamping mold 2 is provided on the frame 1. The clamping mold 2 and the rolling structure 4 are vertically aligned, which facilitates the placement of the paper tube in the clamping mold 2 and the use of the upper rolling structure 4 to perform the barrel mouth rolling work of the paper tube.

[0045] In order to achieve complete paper tube opening edge rolling, the edge rolling structure 4 is connected to the rotary drive structure 5, which drives the edge rolling end to rotate and roll the paper tube opening. The clamping mold 2 is installed on the lifting structure 3, which drives paper tubes of different heights on the clamping mold 2 to enter the upper edge rolling end, realizing the opening edge squeezing and rolling. A chuck structure 8 is also provided between the clamping mold 2 and the lifting structure 3. The chuck structure 8 is used to clamp and position the paper tubes between different openings in the clamping mold 2, so that the upper rotating edge rolling end can rotate relative to the opening. A demolding structure 6 is also provided at the center of the rotating shaft 52 of the edge rolling end. The demolding structure 6 is connected to the displacement drive mechanism, which can perform vertical displacement. After the paper tube opening edge rolling is completed, the paper tube is removed from the clamping mold 2 for easy manual handling, and the edge rolling effect of the paper tube opening is maintained when the paper tube is removed from the clamping mold 2.

[0046] For details, please refer to Figure 2 In this embodiment, the lifting mechanism includes a lifting plate 31, a slide rail 32, a lead screw 33, and a motor 34.

[0047] The lifting plate 31 is fixedly installed on the slider of the slide rail 32, and the track of the slide rail 32 is fixedly installed on the frame 1, so that the lifting plate 31 can be vertically displaced through the slide rail 32. A lead screw 33 is also vertically inserted on the lifting plate 31. The lead screw 33 is threadedly matched with the lifting plate 31. One end of the lead screw 33 is coaxially fixedly connected to the drive end of the motor 34. When the motor 34 drives the lead screw 33 to rotate, it can drive the lifting plate 31 to move vertically to achieve the lifting function.

[0048] For details, please refer to Figure 3 and Figure 4 In this embodiment, the rotary drive structure 5 includes a second motor 51, a rotating shaft 52, and a transmission belt 53.

[0049] The ejection structure 6 includes an extension rod 61 and a tray 62.

[0050] Motor 2 51 is fixedly mounted on frame 1, and shaft 52 is rotatably mounted on top of frame 1. The drive end of motor 2 51 and the top end of shaft 52 are respectively fitted with the two ends of transmission belt 53. When motor 2 51 starts and the drive end rotates, the drive end drives shaft 52 to rotate synchronously on frame 1 through friction between it and transmission belt 53. The lower end of shaft 52 is fixed with flange structure 4, which drives the entire flange structure 4 to rotate.

[0051] The shaft 52 has a vertical through hole through its center. The extension rod 61 slides vertically through the through hole. The top of the extension rod 61 is connected to the displacement drive structure 7, which is a cylinder. The cylinder is fixed on the top of the frame 1. The drive end of the cylinder is fixedly connected to the extension rod 61. The bottom of the extension rod 61 is coaxially fixedly connected to the tray 62. The tray 62 is disc-shaped, and the diameter of the tray 62 is not greater than the inner wall diameter of the paper tube. This allows the tray 62 to extend into the paper tube before the paper tube is rolled, which facilitates the paper tube to be pulled out of the clamping mold 2 after the subsequent rolling is completed.

[0052] It is worth noting that the clamping mold 2 is set as a platform with a circular flange. The diameter of the inner wall of the circular flange is the same as the diameter of the outer wall of the paper tube to be processed, so that the paper tube can be placed on the platform.

[0053] It is worth noting that, please refer to Figure 1 In some embodiments, the chuck structure 8 is configured as a pneumatic chuck, which is provided with at least two pneumatic jaws that can be opened or closed. Each pneumatic jaw is fixedly connected to a part of the platform of the clamping mold 2. The part of the platform on all the pneumatic jaws together constitutes a whole platform with a circular guard, thereby using multiple openable and closable pneumatic jaws to drive the split clamping mold 2 to clamp and fix paper tubes of different diameter specifications.

[0054] Furthermore, when setting up a clamping mold 2 that can accommodate paper tubes of different diameters, its top edge-winding structure 4 should also be adapted to accommodate paper tubes of different diameters for edge-winding operations. Therefore, to achieve the above effect, please refer to... Figures 4-6 In this embodiment, the rolled edge structure 4 includes a rolled edge main disk 41.

[0055] The main edge-rolling disc 41 is coaxially fixed to the bottom end of the rotating shaft 52. The bottom surface of the main edge-rolling disc 41 has at least one annular edge-rolling groove with the opening of the groove facing downwards. Each annular edge-rolling groove is matched with the edge of the paper tube of the corresponding diameter specification. When the edge-rolling operation is performed, the paper tube is gradually raised into the annular edge-rolling groove of the main edge-rolling disc 41 through the lifting structure 3. Then the main edge-rolling disc 41 starts to rotate. During the rotation, the paper tube is slowly raised through the lifting structure 3, so that the edge of the paper tube is pressed into the groove wall of the annular edge-rolling groove, guided and bent inwards, thereby rolling the edge of the tube into the inside to achieve edge-rolling. The continuously rotating main edge-rolling disc 41 can maintain the edge-rolling consistency of each edge of the paper tube through the rotating groove surface and form a shaped edge-rolling crease on the paper tube to maintain the edge-rolling effect of the paper tube.

[0056] Specifically, the groove wall of the annular rim groove of the main rim disc 41 forms a guide arc edge 411 and an inwardly rolled arc edge 412 from the outer ring to the inner ring. Both the guide arc edge 411 and the inwardly rolled arc edge 412 are arc-shaped groove edges, and the curvature of the guide arc edge 411 is greater than that of the inwardly rolled arc edge 412. When the cylindrical barrel edge enters the annular rim groove, it first contacts the guide arc edge 411 and is pre-bent through the large curvature guide arc edge 411 to reduce the situation where the barrel edge is directly folded due to the excessive initial bending angle. Then, the barrel edge at the pre-bent point enters the small curvature inwardly rolled arc edge 412 for a large-angle bend, thereby achieving the inward rolling of the barrel edge.

[0057] Among them, the arc-shaped opening of the guide arc edge 411 faces the inner ring side, which facilitates the guide paper tube barrel edge to bend inward, and the arc-shaped opening of the inward-rolled arc edge 412 faces the outer ring side, which facilitates the guide paper tube barrel edge to be rolled inward.

[0058] Furthermore, although different diameter annular edge grooves can be set on the edge main plate 41 to match different specifications of paper tubes, the arc shape of the aforementioned annular edge groove is a fixed arc. When some paper tubes need to have different inward curling shapes and amplitudes on the tube edge, it is difficult to achieve this using only the aforementioned edge main plate 41. Processing guide arc edges 411 and inward curling arc edges 412 with different arcs on the edge main plate 41 is not only difficult to process (the milling cutters in the prior art are difficult to process surfaces with excessively large arc angles), but also in actual production, manufacturing edge main plates 41 with different arcs will also generate large manufacturing costs, which is not practical.

[0059] To solve the above problems, please refer to Figure 6 In this embodiment, a secondary flange 42 is also fitted and installed on the bottom surface of the main flange 41. The secondary flange 42 and the main flange 41 are matched and installed by screws and screw holes, so that the secondary flange 42 can be quickly disassembled and replaced. On the top surface of the secondary flange 42, at the position corresponding to the annular flange groove of the main flange 41, an annular groove is also provided. The groove surface of the annular groove is also an arc edge. The arc edge of the inner ring side of the annular groove is seamlessly connected with the inner rolled arc edge 412 of the main flange 41, and the arc edge of the outer ring side of the annular groove corresponds vertically to the inner rolled arc edge 412 of the main flange 41.

[0060] During the edge-rolling process, the edge of the paper tube sequentially enters the guide arc edge 411 for pre-bending, then enters the inward-rolling arc edge 412 to begin inward rolling. After the edge slides past the inward-rolling arc edge 412, it will continue to seamlessly enter the annular slot of the edge-rolling sub-disc 42 for further inward rolling. By changing different edge-rolling sub-discs 42 to alter the arc curvature of the annular slot, the inward rolling shape and amplitude of the paper tube edge can be quickly adjusted, thereby reducing processing difficulty and cost and improving adjustment efficiency.

[0061] In some embodiments, please refer to the following for details. Figure 6When the arc edge of the annular slot of the roll edge sub-disc 42 is set as the upward-curving exit arc edge 421, the paper tube barrel edge that starts to roll inward after passing the inward-curving arc edge 412 will roll inward along the upward-curving exit arc edge 421 towards the upper part of the paper tube barrel wall, with the end of the inward roll facing the upper part of the barrel wall.

[0062] In some embodiments, please refer to the following for details. Figure 7 When the arc edge of the annular slot of the roll edge sub-disc 42 is set as the plane exit arc edge 422, the paper tube barrel edge that starts to roll inward after passing the inward rolling arc edge 412 will be horizontally rolled inward along the plane exit arc edge 422 toward the paper tube barrel wall, and the end of the inward roll is perpendicular to the barrel wall.

[0063] In some embodiments, please refer to the following for details. Figure 8 When the arc edge of the annular slot of the roll edge sub-disc 42 is set as the downward-curving exit arc edge 423, the paper tube barrel edge that starts to roll inward after passing the inward-curving arc edge 412 will roll inward along the downward-curving exit arc edge 423 towards the lower part of the paper tube barrel wall, with the end of the inward roll facing the lower part of the barrel wall.

[0064] It is worth noting that in actual production, when a secondary edge disc 42 is installed below the main edge disc 41, although the outer ring edge of the secondary edge disc 42 is located within the projection of the annular edge groove of the main edge disc 41 and will not interfere with the paper tube edge entering the annular edge groove, after the subsequent inner winding of the tube edge is completed, when the paper tube separates from the edge structure 4, the edge position of the paper tube is easily in contact with the annular groove of the secondary edge disc 42, causing interference.

[0065] In this embodiment, when the paper tube is rolled inward, its rolled edge is close to the tube wall and is therefore located at the projection position corresponding to the guide arc edge 411. The outermost of the annular slot of the rolled edge sub-disc 42 is located at the projection position of the inward rolled arc edge 412. The two projection positions are a certain distance apart. When the paper tube moves down with the clamping mold 2, the outermost of the annular slot of the rolled edge sub-disc 42 will abut and press against the bending surface of the paper tube at the inward rolled part. Because the annular slot is biased towards the bending surface side of the paper tube at the inward rolled part, when the paper tube at the inward rolled part is slightly deformed by the pressure (the center of the paper tube at the inward rolled part is hollow, so it has a certain deformation space), the annular slot on the bending surface side can be separated from the paper tube. After separation, the inward rolled part of the paper tube will restore its inward rolled shape due to the small deformation and the bending elasticity of its own paper surface, without affecting the rolled edge effect of the paper tube.

[0066] It is worth noting that the working steps of the demolding structure 6 in the paper tube edge-rolling process are as follows: When the paper tube rises to the bottom surface of the edge-rolling main plate 41 through the lifting structure 3, the displacement driving structure 7 drives the tray 62 to move down a certain distance, so that the tray 62 enters the inside of the paper tube. The circular tray 62 can clean up various paper scraps or debris at the top of the paper tube opening, reducing the occurrence of debris being rolled into it when the edge-rolling is completed. When the edge-rolling work is completed, the lifting structure 3 moves down, and the paper tube moves down and separates from the edge-rolling structure 4. During the downward movement, the chuck structure 8 will drive the clamping mold 2 to release the paper tube. Then the inward-rolled position of the paper tube will contact the tray 62, which has stopped moving down, so that the paper tube is supported by the tray 62 and thus disengages from the clamping mold 2.

[0067] The outer edge of the tray 62 is fixed with an elastic rubber ring. When the tray 62 moves down, the elastic rubber ring can push away debris. After the paper tube moves down and is supported by the tray 62, when the worker takes out the paper tube, the inner curl of the paper tube will squeeze the elastic rubber ring, causing the elastic rubber ring to contract elastically, so that it can be quickly removed from the tray 62, completing the paper tube's edge curling work.

[0068] The various embodiments of this utility model have now been described in detail. To avoid obscuring the concept of this utility model, some details known in the art have not been described. Those skilled in the art will fully understand how to implement the technical solution of this utility model based on the above description. The scope of this utility model is defined by the appended claims.
