Description

Technical Field

[0001] This utility model relates to the field of paper tube production and processing technology, specifically a paper tube forming mechanism. Background Technology

[0002] A paper tube is a cylindrical packaging container made of paper or paperboard, typically made of wood pulp-based paperboard, kraft paper, fiberboard, and paper-adhesive composite materials; a paper tube forming mechanism is a device used to manufacture paper tubes.

[0003] In conventional paper tube forming, the material is directly wound around the surface of the forming roller for processing. As the processing time increases, the material on the surface may wrinkle due to processing operations or external factors, thus affecting the quality of paper tube forming.

[0004] Therefore, in view of this, we studied and improved the existing structure and its shortcomings, and proposed a paper tube forming mechanism. Utility Model Content

[0005] The purpose of this invention is to provide a paper tube forming mechanism to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a paper tube forming mechanism, comprising a base and a first leveling component, wherein a forming component is mounted on the top of the base, the first leveling component is disposed on the forming component, and a second leveling component is disposed on the side of the forming component away from the first leveling component, and a tensioning component is mounted on the side of the forming component close to the second leveling component. The first leveling component comprises a pressure holding roller, a bearing seat, a hydraulic rod and a self-resetting hinge, wherein bearing seats are mounted on both the left and right ends of the pressure holding roller, and a hydraulic rod is vertically mounted on the bottom of the bearing seat, and a self-resetting hinge is connected to the bottom of the hydraulic rod.

[0007] Furthermore, the molding component includes a fixed base, a gearbox, and a servo motor. The gearbox is mounted on one side of the fixed base, and the servo motor is horizontally connected to the side of the gearbox away from the fixed base.

[0008] Furthermore, the molding component also includes a support base and a molding roller. The support base is provided on the side of the fixed base away from the gearbox, and the molding roller passes horizontally through the upper end of the support base.

[0009] Furthermore, the power output ends of the gearbox and the servo motor are connected to each other via a coupling, and the forming roller horizontally passes through the middle of the fixed base and is connected to the power output end of the gearbox via a coupling.

[0010] Furthermore, the second leveling component adopts the same structural configuration as the first leveling component, and the horizontal length of the second leveling component is shorter than the horizontal length of the first leveling component.

[0011] Furthermore, the tensioning assembly includes a movable rod, an anti-slip wheel, a double-stage damping hinge, and a telescopic rod. The surface of the movable rod is equipped with an anti-slip wheel, and one end of the movable rod is connected to the double-stage damping hinge. The end of the double-stage damping hinge away from the movable rod is horizontally equipped with a telescopic rod.

[0012] Furthermore, the anti-slip wheels are arranged at equal intervals on the surface of the movable rod, and the anti-slip wheels and the movable rod are connected and combined by a sleeve connection.

[0013] Furthermore, the end of the telescopic rod away from the dual-segment damping hinge is fixedly installed on the side of the support base, and the movable rod and the forming roller are arranged in a parallel structure.

[0014] This utility model provides a paper tube forming mechanism, which has the following beneficial effects:

[0015] 1. This utility model, by respectively mounting a first leveling component and a second leveling component on both sides of the forming component, uses the same structural setting for both the second leveling component and the first leveling component, except for the difference in horizontal length. Utilizing the structural extensibility of the hydraulic rod, combined with the structural flip-adjustment of the self-resetting hinge at its bottom, the surface of the pressure roller can be pressed against the surface of the forming roller with the paper tube material wound on it, thereby assisting in the winding and forming of the paper tube and achieving the purpose of roller pressing and flattening the material. With the use of the above structure, on the one hand, it can minimize the occurrence of wrinkles in the material during the winding and forming process due to external factors, which would affect the quality of the paper tube forming. On the other hand, it can make real-time synchronous adaptation adjustments according to the thickness of the paper tube being wound, thereby ensuring the processing stability of the paper tube winding and forming process, while also ensuring the operational flexibility of the device structure.

[0016] 2. This utility model, by installing one end of a telescopic rod on the side of a support base, utilizes the telescopic nature of the rod to drive the movable rod to move horizontally. The double-segment damping hinge connecting the movable rod and the telescopic rod allows the movable rod to swing vertically within a certain angle range. This structure allows for tension adjustment of the paper tube material conveyed to the forming roller surface in the upstream equipment, preventing unnecessary wrinkles during processing. Furthermore, multiple sets of anti-slip wheels fitted onto the movable rod surface minimize unnecessary slippage and deviation during material conveying, ensuring material conveying stability. This also further enhances the flexibility of the device structure, facilitates equipment maintenance, and avoids unnecessary structural interference. Attached Figure Description

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0023] like Figures 1 to 4 As shown, a paper tube forming mechanism includes a base 1 and a first leveling component 3. A forming member 2 is mounted on the top of the base 1. The first leveling component 3 is disposed on the forming member 2, and a second leveling component 4 is disposed on the side of the forming member 2 away from the first leveling component 3. A tensioning component 5 is mounted on the side of the forming member 2 close to the second leveling component 4. The first leveling component 3 includes a pressure roller 301, a bearing seat 302, a hydraulic rod 303, and a self-resetting hinge 304. Bearing seats 302 are mounted on both the left and right ends of the pressure roller 301. A hydraulic rod 303 is vertically mounted at the bottom of 302, and a self-resetting hinge 304 is connected to the bottom of the hydraulic rod 303. The second leveling component 4 adopts the same structural setting as the first leveling component 3, and the horizontal length of the second leveling component 4 is shorter than the horizontal length of the first leveling component 3. By utilizing the structural extensibility of the hydraulic rod 303 and the structural flipping adjustment of the self-resetting hinge 304 at its bottom, the surface of the pressure roller 301 can be pressed against the surface of the forming roller 205 with the paper tube material wound on it, so as to assist the paper tube winding and forming.

[0024] like Figures 1 to 4As shown, the molding component 2 includes a fixed base 201, a gearbox 202, and a servo motor 203. The gearbox 202 is mounted on one side of the fixed base 201, and the servo motor 203 is horizontally connected to the side of the gearbox 202 away from the fixed base 201. The molding component 2 also includes a support base 204 and a molding roller 205. The support base 204 is provided on the side of the fixed base 201 away from the gearbox 202, and the molding roller 205 is horizontally passed through the upper end of the support base 204. The power output ends of the gearbox 202 and the servo motor 203 are connected to each other through a coupling, and the molding roller 205 horizontally passes through the middle of the fixed base 201 and is connected to the power output end of the gearbox 202 through a coupling. The tensioning component 5 includes a movable rod 501, an anti-slip wheel 502, a double-stage damping hinge 503, and a telescopic rod 504. The surface of the movable rod 501 is equipped with the anti-slip wheel 502. 02, and one end of the movable rod 501 is connected to a double-segment damping hinge 503, and the end of the double-segment damping hinge 503 away from the movable rod 501 is horizontally mounted with a telescopic rod 504. Anti-slip wheels 502 are evenly arranged on the surface of the movable rod 501, and the anti-slip wheels 502 and the movable rod 501 are connected by a sleeve. The end of the telescopic rod 504 away from the double-segment damping hinge 503 is fixedly installed on the side of the support base 204, and the movable rod 501 and the forming roller 205 are arranged in a parallel structure. The telescopic extension of the telescopic rod 504 can drive the movable rod 501 to move and adjust horizontally, and the double-segment damping hinge 503 connected between the movable rod 501 and the telescopic rod 504 can drive the movable rod 501 to swing up and down within a certain angle range in the vertical direction.

[0025] In summary, as Figures 1 to 4 As shown, when the paper tube forming mechanism is in use, the paper tube material to be wound and formed is first connected to the surface of the forming roller 205. At this time, the entire first leveling component 3 and the second leveling component 4, under the structural action of the self-resetting hinge 304 and the structural extension and retraction of the hydraulic rod 303, press the topmost pressure roller 301 against the surface of the forming roller 205 with the paper tube material wound on it, thereby forming a roller pressing structure on both sides of the forming roller 205.

[0026] Then, as needed, the position of the movable rod 501 with anti-slip wheel 502 mounted on its surface is adjusted by utilizing the structural extensibility of the telescopic rod 504 and the structural swing adjustment of the double-section damping hinge 503. This adjusts the tensioning component 5 relative to the second leveling component 4, thereby achieving the tensioning effect on the conveyed paper tube material.

[0027] Then, driven by the servo motor 203 and in conjunction with the structural transmission of the gearbox 202, the forming roller 205 on one side of the fixed seat 201 is rotated, thereby winding and forming the material on the surface of the forming roller 205, and the wound paper tube is conveyed from the other end of the forming roller 205 to the downstream equipment.
