Technical Field

[0001] The utility model relates to an adjustable double-roller tension frame, belonging to the field of cloth processing. Background Art

[0002] During the processing and production of elastic materials, a tension frame is needed to adjust the tension of the elastic material to ensure the elastic force of the elastic material.

[0003] Conventional double-roller tension frames are difficult to adjust and therefore difficult to adapt to the production needs of different elastic materials.

[0004] The utility model proposes a new solution to the above problems. Utility Model Content

[0006] The purpose of the utility model can be achieved by adopting the following technical solutions:

[0007] An adjustable double-roller tension frame comprises a workbench, a fixed roller frame fixedly mounted on the upper surface of the workbench, and a guide rail fixedly mounted on the upper surface of the workbench, the inner wall of the guide rail is slidably connected to a slider, the upper surface of the slider is fixedly connected to a movable roller frame, the inner walls of the fixed roller frame and the movable roller frame are both rotatably connected to connecting rollers, the surface of the fixed roller frame is fixedly connected to a mounting frame, the surface of the mounting frame is fixedly connected to a cylinder, the side of the movable roller frame is fixedly connected to a connecting roller, and the output end of the cylinder is fixedly connected to the connecting roller.

[0008] Preferably, a weight-reducing cavity is provided inside the connecting roller, and an anti-slip sleeve is fixedly connected to the surface of the connecting roller.

[0009] Preferably, a mounting block is fixedly connected to the upper surface of the workbench, and a bidirectional electric push rod is fixedly connected to the upper surface of the mounting block.

[0010] Preferably, both output ends of the bidirectional electric push rod are fixedly connected to a mounting rod, and one end of the mounting rod is fixedly connected to a limiting wheel.

[0011] Preferably, a guide frame is fixedly connected to the upper surface of the workbench, a sliding sleeve is inlaid on the surface of the mounting rod, and an inner wall of the sliding sleeve is slidably connected to the guide frame.

The cylinder extends so that the fixed roller frame and the movable roller frame move away from each other, thereby stretching the elastic material. Conversely, the cylinder contracts, thereby relaxing the elastic material. Vibration is easily generated during the transfer device, causing the damping upper seat and the damping lower seat to slide, thereby causing the spring to deform and reduce vibration, making the device less likely to be damaged.

[0023] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is described in further detail below with reference to embodiments and drawings, but the implementation manner of the present invention is not limited thereto.

[0024] like Figures 1-6As shown, this embodiment provides an adjustable double-roller tension frame, including a workbench 1, a fixed roller frame 2 fixedly mounted on the upper surface of the workbench 1, and a guide rail 4 fixedly mounted on the upper surface of the workbench 1, the inner wall of the guide rail 4 is slidably connected with a slider 5, the upper surface of the slider 5 is fixedly connected with a movable roller frame 3, the inner walls of the fixed roller frame 2 and the movable roller frame 3 are both rotatably connected with connecting rollers 8, the surface of the fixed roller frame 2 is fixedly connected with a mounting frame 6, the surface of the mounting frame 6 is fixedly connected with a cylinder 7, the side of the movable roller frame 3 is fixedly connected with a connecting roller 8, the output end of the cylinder 7 is fixedly connected to the connecting roller 8, the elastic material is wound around the two connecting rollers 8, and then the cylinder 7 is started. The cylinder 7 extends to make the fixed roller frame 2 and the movable roller frame 3 move away from each other, thereby stretching the elastic material, and conversely, the cylinder 7 contracts, thereby relaxing the elastic material.

[0025] In this embodiment, if Figure 1 and Figure 3 As shown, a weight-reducing cavity 9 is provided inside the connecting roller 8, and an anti-slip sleeve 10 is fixedly connected to the surface of the connecting roller 8. The weight-reducing cavity 9 reduces the weight of the connecting roller 8, and the anti-slip sleeve 10 improves the anti-slip ability of the connecting roller 8.

[0026] In this embodiment, if Figure 1 and Figure 4 As shown, the upper surface of the workbench 1 is fixedly connected to a mounting block 19, and the upper surface of the mounting block 19 is fixedly connected to a bidirectional electric push rod 20. Both output ends of the bidirectional electric push rod 20 are fixedly connected to a mounting rod 11, and one end of the mounting rod 11 is fixedly connected to a limiting wheel 21. The upper surface of the workbench 1 is fixedly connected to a guide frame 13, and the surface of the mounting rod 11 is inlaid with a sliding sleeve 12. The inner wall of the sliding sleeve 12 is slidably connected to the guide frame 13. The bidirectional electric push rod 20 extends or contracts, thereby driving the mounting rod 11 to move. The moving direction of the mounting rod 11 is limited by the cooperation of the sliding sleeve 12 and the guide frame 13, and the position of the limiting wheel 21 is adjusted to limit the position of the elastic material, so that the elastic material is not easily detached from the anti-slip sleeve 10.

[0027] In this embodiment, if Figure 1 、 Figure 5 and Figure 6 As shown, the lower surface of the workbench 1 is fixedly connected with a damping upper seat 16, and the surface of the damping upper seat 16 is slidably connected with a damping lower seat 14. A spring 15 is arranged inside the damping lower seat 14, and a connecting hole 17 is opened on the lower surface of the damping lower seat 14. The inner wall of the connecting hole 17 is buckled with an anti-slip pad 18. The anti-slip pad 18 improves the anti-slip ability of the damping lower seat 14. Vibration is easily generated during the transportation of the device, causing the damping upper seat 16 and the damping lower seat 14 to slide, thereby causing the spring 15 to deform and reduce vibration, making the device less likely to be damaged.

[0028] In this embodiment, if Figures 1-6As shown, the working principle of an adjustable double-roller tension frame provided in this embodiment is as follows:

[0029] The elastic material is wound around the two connecting rollers 8, and then the cylinder 7 is started. The cylinder 7 extends to make the fixed roller frame 2 and the movable roller frame 3 move away from each other, thereby stretching the elastic material. Conversely, the cylinder 7 contracts to relax the elastic material. The bidirectional electric push rod 20 extends or contracts, thereby driving the installation rod 11 to move. The moving direction of the installation rod 11 is limited by the cooperation of the sliding sleeve 12 and the guide frame 13, and the position of the limiting wheel 21 is adjusted to limit the position of the elastic material, so that the elastic material is not easily separated from the anti-slip sleeve 10.

[0030] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and concept of the present invention within the scope disclosed by the present invention, which falls within the protection scope of the present invention.
