Description
Technical Field
[0001] The utility model relates to the technical field of packaging, in particular to a coil anti-jump device. Background Art
[0002] When a packaging machine performs packaging work on coils such as paper rolls, it is necessary to roll the coils such as paper rolls and wind packaging paper or packaging film around the outer periphery of the coils such as paper rolls. When the coils such as paper rolls are rolling, some coils are prone to jump out of the driving roller due to their light weight, so it is necessary to use a coil anti-jump device.
[0003] Chinese Patent Publication No. CN217706611U, published on November 1, 2022, discloses a coil anti-jump device, which includes a base, a swing arm hinged to the base, and a coil pressing structure connected to the swing arm. The coil pressing structure is located above the coil to be pressed, and the coil pressing structure can contact and limit the coil to be pressed.
[0004] For example, the existing coil anti-jump device as described above swings the swing arm on the base to drive the coil pressing structure to contact and limit the coil to be pressed, or drive the coil pressing structure to separate from the coil to be pressed. When the coil pressing structure contacts and limits the coil to be pressed, the coil pressing structure presses on the top of the coil to be pressed to prevent the coil to be pressed from jumping at the working station. In the specific implementation process, after the swing arm drives the pressure roller to be combined above the paper roll, the vertical position of the pressure roller is relatively fixed. As the packaging film is wound, the thickness of the outer side of the paper roll will change to a certain extent, and the pressure roller is prone to over-fit with the winding film, resulting in damage to the winding film. Therefore, it is urgent to propose a corresponding coil anti-jump device to solve the above problems. Summary of the Utility Model
[0005] The purpose of the utility model is to provide a coil anti-jump device to solve the above problems.
[0006] To achieve the above purpose, the utility model adopts the following technical scheme:
[0007] A coil anti-jump device includes a first bracket and a second bracket. The first bracket and the second bracket are fixedly connected. A connecting rod is rotatably connected to the side of the second bracket away from the first bracket. A driving component for pushing the connecting rod is arranged between the connecting rod and the first bracket. An open end of the connecting rod is fixedly installed with a swing arm. A rotating rod is rotatably connected to the open end of the swing arm. A connecting frame is fixedly connected to the outer surface of the rotating rod. A pressure roller is rotatably connected to the outer surface of the connecting frame. An elastic component for axially resetting the rotating rod is arranged between the rotating rod and the swing arm.
[0008] Preferably, a second push cylinder is fixedly installed at the bottom of the connecting rod. The output end of the second push cylinder is fixedly connected to the bottom of the swing arm, and a sliding fit portion is provided between the inner wall of the swing arm and the connecting rod.
[0009] Preferably, the sliding fit portion includes a slide bar. The outer wall of the slide bar is slidably connected to the inner wall of the swing arm, and the cross-section of the slide bar is in a rectangular structure.
[0010] Preferably, the first bracket and the second bracket are fixedly connected by a cross bar, and connecting pieces are fixedly installed on the outer walls of the first bracket and the second bracket.
[0011] Preferably, the drive assembly includes a first push cylinder. The outer wall of the first push cylinder is rotatably connected to the outer wall of the first bracket, and the output end of the first push cylinder is hinged to the outer wall of the connecting rod.
[0012] Preferably, the elastic assembly includes a connecting block. The connecting block is fixedly connected to the rotating rod. A spring is fixedly installed between the connecting block and the swing arm, and the inner wall of the spring is in contact with the outer wall of the rotating rod.
[0013] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present utility model are as follows:
[0014] 1. In this application, when the first push cylinder works to push the connecting rod, the connecting rod drives the swing arm through the slide bar. The swing arm drives the rotating rod and the connecting frame to deflect until the pressure roller is lapped on the top of the paper roll. In the initial state, the spring positions the swing arm and the rotating rod in a stable state through its own elastic force, and the pressure roller stably abuts against the paper roll, realizing the vertical anti-jump of the paper roll. As the winding film is wound around the outside of the paper roll, while the pressure roller always maintains a state of being in contact with the top of the paper roll, the connecting frame drives the rotating rod to rotate, and the spring is expanded, thereby ensuring stable limiting of the paper roll and avoiding excessive cooperation between the pressure roller and the winding belt, thus improving the use effect of the coil anti-jump device.
[0015] 2. In this application, when the diameter of the paper roll changes, the output end of the second push cylinder provides a traction force for the swing arm, so that the inner wall of the swing arm and the outer wall of the slide bar are in sliding fit, thereby realizing synchronous adjustment of the position of the pressure roller, replacing the traditional integral swing arm design. There is no need for the paper roll to adapt to the position of the pressure roller, so that the pressure roller can be stably combined on the top of the paper roll. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.
[0023] Please refer to Figures 1-4 , the present invention provides a technical solution:
[0024] The coiled material anti-jump device includes a first support 1 and a second support 2. The first support 1 and the second support 2 are fixedly connected. A connecting rod 4 is rotatably connected to one side of the second support 2 away from the first support 1. A driving component for pushing the connecting rod 4 is arranged between the connecting rod 4 and the first support 1. The open end of the connecting rod 4 is fixedly installed with a swing arm 5. The open end of the swing arm 5 is rotatably connected to a rotating rod 6. The outer wall of the rotating rod 6 is fixedly connected with a connecting frame 7. And a pressure roller 8 is rotatably connected to the outer wall of the connecting frame 7. And an elastic component for axially resetting the rotating rod 6 is arranged between the rotating rod 6 and the swing arm 5;
[0025] When the first push cylinder 3 works to push the connecting rod 4, the connecting rod 4 drives the swing arm 5 through the slide bar 10. The swing arm 5 drives the rotating rod 6 and the connecting frame 7 to deflect until the pressure roller 8 is lapped on the top of the paper roll. In the initial state, the spring 12 maintains the stable state of the swing arm 5 and the rotating rod 6 through its own elastic force. The pressure roller 8 stably abuts against the paper roll, realizing the vertical anti-jump of the paper roll. As the winding film is wound around the outside of the paper roll, while the pressure roller 8 always keeps in contact with the top of the paper roll, the connecting frame 7 drives the rotating rod 6 to rotate, and the spring 12 is expanded, thereby ensuring the stable limit of the paper roll and avoiding the over-matching between the pressure roller 8 and the winding belt, thus improving the use effect of the coiled material anti-jump device.
[0026] Specifically, as Figure 2 And Figure 4As shown, a push cylinder 2 9 is fixedly installed at the bottom of the connecting rod 4, and the output end of the push cylinder 2 9 is fixedly connected to the bottom of the swing arm 5, and a sliding fitting portion is provided between the inner surface wall of the swing arm 5 and the connecting rod 4, and the sliding fitting portion includes a slide bar 10, and the outer wall of the slide bar 10 is slidably connected to the inner surface wall of the swing arm 5, and the cross-section of the slide bar 10 is a rectangular structure, which can limit the axial deflection of the swing arm 5. When the diameter of the paper roll changes, the output end of the push cylinder 2 9 provides traction for the swing arm 5, so that the inner surface wall of the swing arm 5 and the outer surface wall of the slide bar 10 slide and cooperate, thereby realizing the synchronous adjustment of the position of the pressure roller 8, replacing the traditional integrated swing arm 5 design, and no paper roll is required to adapt to the position of the pressure roller 8, so that the pressure roller 8 can be stably combined on the top of the paper roll.
[0027] Specifically, such as Figure 2 and Figure 3 As shown, bracket 1 and bracket 2 are fixedly connected by a cross bar, and the outer walls of bracket 1 and bracket 2 are fixedly installed with connecting plates for installation of the entire device. The driving component includes a push cylinder 3, the outer wall of the push cylinder 3 is rotatably connected to the outer wall of bracket 1, and the output end of the push cylinder 3 is hinged to the outer wall of the connecting rod 4. The push cylinder 3 works to push the connecting rod 4, and the connecting rod 4 is linked to the swing arm 5 through the slide bar 10. The elastic component includes a connecting block 11, which is fixedly connected to the rotating rod 6. A spring 12 is fixedly installed between the connecting block 11 and the swing arm 5, and the inner wall of the spring 12 is in contact with the outer wall of the rotating rod 6. In the initial state, the spring 12 maintains the stable state of the swing arm 5 and the rotating rod 6 through its own elastic force. As the wrapping film is wound around the outside of the paper roll, the pressure roller 8 always maintains a state of contact with the top of the paper roll. At the same time, the connecting frame 7 will drive the rotating rod 6 to rotate, and the spring 12 is expanded, thereby ensuring the stable limit of the paper roll.
[0028] Working principle: the push cylinder 3 works to push the connecting rod 4, the connecting rod 4 is linked to the swing arm 5 through the slide rod 10, and the swing arm 5 drives the rotating rod 6 and the connecting frame 7 to deflect until the pressure roller 8 is overlapped on the top of the paper roll. In the initial state, the spring 12 maintains the stability of the swing arm 5 and the rotating rod 6 through its own elastic force, and the pressure roller 8 is stably in contact with the paper roll to achieve vertical anti-jump of the paper roll. As the wrapping film is wound around the outside of the paper roll, the pressure roller 8 always keeps in contact with the top of the paper roll, and the connecting frame 7 drives the rotating rod 6 When the paper roll is rotated, the spring 12 is expanded, thereby ensuring the stable position limit of the paper roll and avoiding excessive fit between the pressure roller 8 and the winding belt, thereby improving the use effect of the roll anti-jump device. When the diameter of the paper roll changes, the output end of the push cylinder 2 9 provides traction for the swing arm 5, so that the inner surface wall of the swing arm 5 and the outer surface wall of the slide rod 10 slide and fit, thereby realizing the synchronous adjustment of the position of the pressure roller 8, replacing the traditional integrated swing arm 5 design, and no paper roll is required to adapt to the position of the pressure roller 8, so that the pressure roller 8 can be stably combined with the top of the paper roll.
