Description

Technical Field

[0001] This utility model relates to the field of paper tube processing technology, specifically to a steel ring assembly device for circular paper tubes. Background Technology

[0002] Paper tubes are cylindrical structures made of paper and used as packaging containers. They are generally made of kraft paper. To enhance the structural strength of the paper tube, steel rings are installed at both ends and on the lid for reinforcement, further enhancing the structural strength of the paper tube and ensuring the protection of the contents.

[0003] When fitting steel rings to the ends of paper tubes, the steel rings are usually pre-fitted onto the ends of the paper tubes. Then, the assembly of the steel rings and paper tubes is placed on the steel ring fitting machine and clamped by turntables on both sides. Inserting discs that can be inserted into the paper tubes are set on the surface of the turntables. Then, the rotating rollers are driven by hydraulic cylinders or air cylinders to roll tightly against the outside of the steel rings. The inserting discs on the inside of the paper tubes provide support, pressing the steel rings and the ends of the paper tubes together.

[0004] When the two turntables approach each other, they will squeeze the two ends of the paper tube. Since the two ends of the paper tube do not have a support structure inside, the steel ring and the analgesic connection are easily squeezed and bent during the squeezing, which will result in defective products. Therefore, further improvements can be made. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides the following technical solution: a steel ring assembly device for circular paper tubes, comprising a housing and an electric slide rail. An electric slider is slidably connected inside the electric slide rail. A servo motor is fixedly installed on both the electric slider and the top of the housing. A turntable is fixedly installed at one end of the output shaft of the servo motor. An inner support ring is fixedly installed on one side of the two turntables opposite to each other. The outer side of the inner support ring has a protruding annular flange. An electric telescopic rod is fixedly installed at the right end of the electric slide rail, and the telescopic end of the electric telescopic rod is fixedly connected to one side of the electric slider. An inner support assembly for supporting the end of the paper tube is provided at the center of one side of the two turntables opposite to each other and inside the inner support ring.

[0006] As an optimization, the inner support assembly includes a fixed tube fixedly installed at the center of the turntable. A groove is provided on the outer side of the fixed tube. A drive component for transmission is provided inside the fixed tube. A support component driven by the fixed tube is provided on the outer side of the fixed tube at the groove. By activating the drive component, the support component can be driven to open outward, thereby supporting the end of the paper tube against the inner wall of the paper tube and minimizing the bending of the paper tube.

[0007] As an optimization, the driving component includes an electric push rod fixedly installed inside the fixed tube. The telescopic end of the electric push rod is fixedly installed with a movable slider, and the movable slider is slidably connected inside the fixed tube. Movable seats are fixedly installed on the outer side array of the movable slider.

[0008] As an optimization, the movable seat is provided with four sets of corresponding slide groove arrays, and the movable seat is slidably connected in the slide groove.

[0009] As an optimization, the support members are arranged around the outside of the fixed tube, and four sets are arranged in an array corresponding to the sliding groove.

[0010] As an optimization, the support includes a fixed seat fixedly installed on the outside of the end of the fixed tube, and a support plate is rotatably connected to the top of both the fixed seat and the movable seat, with a support seat hinged to the top of the support plate.

[0011] As an optimization, a limiting groove is formed inside the support plate, and a sliding rod is slidably inserted into the limiting groove. Horizontal connecting plates are fixedly installed at both ends of the sliding rod.

[0012] The beneficial effects of this utility model are:

[0013] The steel ring assembly for this circular paper tube uses an electric push rod to drive the movable slider, which in turn moves the movable seat. This causes the support plate to tilt upwards, supporting the support seat against the inner wall of the paper tube. Simultaneously, the connecting plate restricts the sliding rods on both sides to be within the limiting grooves, ensuring that the support plates on both sides remain symmetrical. This allows the support seat to stably support the inner wall of the paper tube outwards, thus providing support to the inner wall at the end of the paper tube and minimizing the risk of the paper tube bending due to excessive pressure.

[0019] In the description of this application, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-2 A steel ring assembly device for circular paper tubes includes a housing 1 and an electric slide rail 2. An electric slider 3 is slidably connected inside the electric slide rail 2. A servo motor 4 is fixedly mounted on both the electric slider 3 and the top of the housing 1. A turntable 5 is fixedly mounted on one end of the output shaft of the servo motor 4. An inner support ring 6 is fixedly mounted on the opposite side of the two turntables 5. The outer side of the inner support ring 6 has a protruding annular flange 7. An electric telescopic rod 8 is fixedly mounted on the right end of the electric slide rail 2, and the telescopic end of the electric telescopic rod 8 is fixedly connected to one side of the electric slider 3. An inner support component 9 for supporting the ends of the paper tube is provided at the center of the opposite side of the disc 5 and inside the inner support ring 6. The electric telescopic rod 8 can extend and retract to drive the electric slider 3 to slide inside the electric slide rail 2, thereby adjusting the distance between the two inner support rings 6 to accommodate paper tubes of different lengths. When the right turntable 5 is pushed closer, the annular flange 7 will squeeze the steel ring, causing the steel ring to deform and tightly fit around both ends of the paper tube. The inner support component 9 supports the inner walls of both ends of the paper tube, which can minimize the risk of the paper tube bending due to excessive pressure.

[0022] Please see Figure 2-3The inner support assembly 9 includes a fixed tube 10 fixedly installed at the center of the turntable 5. A groove 11 is provided on the outer side of the fixed tube 10. A drive component for transmission is provided inside the fixed tube 10. A support component driven by the fixed tube 10 is provided on the outer side of the fixed tube 10 at the groove 11. By activating the drive component, the support component can be driven to open outward, thereby supporting the end of the paper tube against the inner wall of the paper tube and avoiding bending the paper tube as much as possible.

[0023] Please see Figure 3-4 The driving component includes an electric push rod 12 fixedly installed inside the fixed tube 10. A movable slider 13 is fixedly installed at the telescopic end of the electric push rod 12, and the movable slider 13 is slidably connected inside the fixed tube 10. Movable seats 14 are fixedly installed in an array on the outer side of the movable slider 13. Four sets of movable seats 14 are arranged in an array corresponding to the slide groove 11, and the movable seats 14 are slidably connected inside the slide groove 11. By activating the electric push rod 12, the movable slider 13 can be pushed to slide, which in turn drives the movable seats 14 to slide synchronously to transmit power to the support component.

[0024] Please see Figure 3-4 The support members are arranged around the outside of the fixed tube 10, and four sets are arranged in an array corresponding to the slide groove 11. The support members include a fixed seat 15 fixedly installed on the outside of the end of the fixed tube 10. The top of the fixed seat 15 and the movable seat 14 are rotatably connected to the support plate 16. The top of the support plate 16 is hinged to the support seat 17. The sliding of the movable seat 14 will drive the support plate 16 to deflect upward and support it, which will then drive the support seat 17 to abut against the inner wall of the paper tube, thereby providing support for the inner wall of the end of the paper tube.

[0025] Please see Figure 3-4 The support plate 16 has a limiting groove 18 inside, and a slide rod 19 is slidably inserted into the limiting groove 18. Horizontal connecting plates 20 are fixedly installed at both ends of the slide rod 19. By limiting the slide rods 19 on both sides to be located in the limiting groove 18 through the connecting plates 20, the support plates 16 on both sides can be kept symmetrical, which facilitates the upward support of the support base 17.

[0026] In use, the electric telescopic rod 8 is first activated to extend and retract, which drives the electric slider 3 to slide inside the electric slide rail 2. This allows the spacing between the inner support rings 6 on both sides to be adjusted. Then, the paper tube can be placed between the two annular flanges 7 and fitted onto the outside of the inner support rings 6. Then, the electric telescopic rod 8 is used to push the right turntable 5 closer to the left, which will squeeze the steel ring through the annular flange 7, causing the steel ring to deform and tightly fit around both ends of the paper tube.

[0027] At the same time, by activating the electric push rod 12, the movable slider 13 can be pushed to slide, which in turn drives the movable seat 14 to slide synchronously. The sliding of the movable seat 14 will cause the support plate 16 to deflect upward and support it, which in turn causes the support seat 17 to abut against the inner wall of the paper tube for support. Meanwhile, by using the connecting plate 20 to restrict the sliding rods 19 on both sides to be located in the limiting groove 18, the support plates 16 on both sides can be kept symmetrical, so that the support seat 17 can stably support the inner wall of the paper tube outward.

[0028] In summary, the steel ring assembly for the circular paper tube can be activated by starting the electric push rod 12, which pushes the movable slider 13 to slide the movable seat 14. This causes the support plate 16 to deflect upwards, which in turn causes the support seat 17 to press against the inner wall of the paper tube for support. At the same time, the connecting plate 20 restricts the sliding rods 19 on both sides to be within the limiting groove 18, thus ensuring that the support plates 16 on both sides remain symmetrical. This allows the support seat 17 to stably support the inner wall of the paper tube outwards, thereby providing support for the inner wall at the end of the paper tube and minimizing the risk of the paper tube bending due to excessive pressure.
