Description

Technical Field

[0001] The utility model relates to the technical field of roller shafts, in particular to a roller support device for a long roller. Background Art

[0002] Rollers refer to cylindrical objects that can rotate in machinery. Power sources are often used to drive rollers in machinery. In order to reduce the load on the power source, thicker rollers generally use hollow structures to reduce weight. However, the ability of a long roller with a hollow structure to withstand radial forces at different positions along its length is often different, so it will deform. In the prior art, the wall thickness of the long roller is generally increased to obtain greater strength and greater anti-deformation properties, which undoubtedly increases the load power of the power source (usually a motor).

[0023] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0024] A roller device for long rollers, see Figure 1-5 , including a roller seat 2, on which two rollers 3 are rotatably connected, and the central axes of the two rollers 3 are parallel. When installed, the two rollers 3 are placed under the long roller 1, and the central axes of the two rollers 3 are parallel to the central axis of the long roller 1, and the two rollers 3 are in close and tangential contact with the circumferential surface of the long roller 1. An overlong roller is easy to deform and bend in the middle. When the long roller 1 is deformed, the deformed part contacts the roller 3, and the deformed part is corrected as the long roller 1 rotates, ensuring that the long roller 1 is not easily deformed during long-term use.

[0025] In addition, by arranging the roller 3 to support the long roller 1, the long roller 1 is not easily deformed, and objectively the long roller 1 with a smaller wall thickness can be used in the workpiece, thereby overcoming the problem of obtaining a greater non-deformation characteristic by increasing the wall thickness of the long roller 1.

[0026] See also Figure 5 The roller seat 2 has two arc-shaped cavities 21, and the two rollers 3 coaxially rotate in the arc-shaped cavities 21 of the roller seat 2 through the shaft 22. The upper side of the roller 3 has a part extending out of the arc-shaped cavity 21. By setting the arc-shaped cavity 21, the roller 3 can be limited to prevent it from escaping from the arc-shaped cavity 21, thereby improving safety.

[0027] In this embodiment, a frame 4 is also included, a slide rail 5 is arranged in the middle of the frame 4, and the roller seat 2 is slidably connected to the slide rail 5. Two parallel slide rails 5 are preferably arranged on the frame 4, and two notches are provided below the roller seat 2, which are slidably connected to the two slide rails 5 respectively. A linear module 7 is fixedly connected to the frame 4, and the linear module 7 is arranged in parallel below the two slide rails 5. The sliding seat of the linear module 7 is fixedly connected to the roller seat 2, and the linear module 7 drives the roller seat 2 to slide along the axial direction of the roller 3 on the slide rail 5. The roller seat 2 is driven to move by the linear module 7, so that the roller seat 2 can drive the roller 3 to move to different positions in the axial direction of the long roller 1, and different positions of the long roller 1 can be supported and deformed.

[0028] In addition, a side rail 6 parallel to the slide rail 5 is provided on the frame 4, and a slide seat 8 is slidably connected to the side rail 6; a detection device 9 is provided on the slide seat 8, and the detection device 9 includes a rotating rod 91, a support rod 92 fixed on the upper surface of the slide seat 8, and a contact wheel 93 fixed on the upper end of the rotating rod 91, the rotating rod 91 is hinged to the upper end of the support rod 92 at its middle, and the lower end of the rotating rod 91 is horizontally bent to form a flat section 911, and a trigger switch 94 is fixed on the upper surface of the flat section 911, and a tension spring 95 is fixedly connected between the lower surface of a section of the rotating rod 91 close to the contact wheel 93 and the upper surface of the slide seat 8; a bent plate 96 is fixed on the upper surface of the slide seat 8, and the bent plate 96 has a blocking section 961 extending to the top of the trigger switch 94; a control panel 10 is provided on the frame 4, and the trigger switch 94 and the linear module 7 are electrically connected to the control panel 10.

[0029] The contact wheel 93 contacts the surface of the long roller 1. When the long roller 1 is deformed, the deformed part will push the contact wheel 93 during rotation and drive the rotating rod 91 to rotate. The rotating lower end drives the trigger switch 94 to move. When it touches the blocking section 961, the trigger switch 94 is triggered and transmits a signal to the control panel 10. The control panel 10 controls the linear module 7 to drive the roller seat 2 to move to the deformed position, thereby supporting and correcting the deformed part. By moving the detection device 9 along the slide 8, the deformation of different positions on the long roller 1 can be detected, and the roller seat 2 can be driven to move in time for correction, thereby improving the response capability.

[0030] In addition, a cylinder 11 is fixed on the frame 4, and the telescopic end of the cylinder 11 is connected to the slide 8 to drive the slide 8 to slide along the length direction of the side rail 6. The cylinder 11 is also electrically connected to the control panel 10. The control panel 10 controls the cylinder 11 to extend and retract regularly and drive the slide 8 to move, so that the deformed part of the long roller 1 can be automatically detected regularly.

[0031] In this embodiment, side rails 6 are provided on both sides of the slide rail 5 on the frame 4, and slide seats 8 are slidably connected to the two side rails 6.
