Description

Technical Field

[0001] The utility model relates to the technical field of dynamic balance detection devices, in particular to a non-woven fabric roller dynamic balance detection device. Background Art

[0002] The non-woven fabric roller is a roller in a calender during the post-processing of non-woven fabrics. The roller contains an iron core and is covered with sheet-like non-woven fabric. It is pressed and formed after lathing. After it is produced, it needs to be dynamically balanced before leaving the factory to ensure its normal use.

[0003] The publication number in the existing public technology is: CN216524564U. A rotating roller dynamic balance detection device includes a laterally movable detection component, the detection component is fixedly connected to the screw sleeve, a transmission screw is inserted inside the screw sleeve, and the transmission screw is installed in the screw seat; the detection component includes a mounting block, an upper guide sleeve and a lower guide sleeve are installed in the mounting block, and a vertically arranged detection head is arranged inside the upper guide sleeve and the lower guide sleeve, and a compression spring and a pressure sensor are arranged at the top of the detection head in sequence; the two ends of the screw seat are respectively connected to the vertical telescopic cylinder, the vertical telescopic cylinder is fixed to the top of the crossbeam, and the two ends of the crossbeam are respectively provided with longitudinal beams arranged vertically therewith, and the inner sides of the longitudinal beams facing each other are respectively provided with rotating components, and the two rotating components can move toward or away from each other. The utility model can reduce the existence of detection blind spots, make the dynamic balance detection process more comprehensive, facilitate the installation of the roller body, and significantly improve the dynamic balance detection efficiency.

[0004] However, the above patent still has certain disadvantages when used: although it can determine whether the roller is in dynamic balance through the change in pressure value detected by the pressure sensor, the visualization degree of the detected value is not high. Although some equipment can display the dynamic balance value of the roller on the computer, after leaving the terminal, the personnel cannot obtain the corresponding data on the surface of the roller in time, and the overall detection intuitiveness is not very good. When processing the rollers later, the personnel are likely to confuse multiple rollers together, and even need to perform the detection operation twice, which increases the labor intensity of the operation, is not conducive to the operation use, and the overall practicality is not very ideal.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0031] In one embodiment, a bidirectional screw rod 2 is provided in the middle position on the top of the workbench 1, one end of the bidirectional screw rod 2 passes through one side of the workbench 1 and is connected to the second motor 19, and a movable seat 3 is symmetrically sleeved on the outer periphery of both ends of the bidirectional screw rod 2. The movement of the movable seat 3 facilitates personnel to fix different types of non-woven fabric rollers, which is convenient for subsequent detection operations.

[0032] In one embodiment, a bearing groove 4 is opened in the middle position of the surface of the movable seat 3, and a rotating disk 5 is rotatably connected inside the bearing groove 4. One end of the rotating disk 5 passes through one side of the movable seat 3 and is connected to the third motor 20.

The controller is a common control device and is only used here to control the operation of the equipment in the structure. It is not marked in the figure and there are various types on the market, so it will not be described in detail.

[0036] In one embodiment, the pressure sensor 13 is electrically connected to an external terminal via a wire. The external terminal may be a computer.

[0038] Working principle: In actual use, personnel can insert the two ends of the non-woven roller that needs to be dynamically balanced into the internal position of the bearing groove 4 on the surface of the moving seat 3, and the moving seat 3 can drive the rotation of the bidirectional screw rod 2 through the operation of the second motor 19, so as to realize the two groups of structures approaching or moving away from each other, so as to facilitate the fixing operation of the non-woven roller, and then the operation of the third motor 20 can drive the rotating disk 5 connected thereto to rotate, and at this time, the rotating disk 5 can drive the non-woven roller clamped by it to rotate, so as to realize the dynamic balance detection operation, and when the non-woven roller rotates, the moving plate 6 can be moved down as a whole through the ejection of the vertical telescopic cylinder 8, so that the detection head 17 on its surface can contact the surface of the non-woven roller. After the detection head 17 contacts the non-woven roller, it will compress the internal compression spring 14, so that the pressure acting on the pressure sensor 13 changes. The change in pressure can determine whether the non-woven roller is in dynamic balance. If the non-woven roller is not dynamically balanced, then Then the pressure acting on the pressure sensor 13 will change significantly. At this time, the motor 11 can be triggered to rotate according to the difference between the amount of pressure change and the amount at standard time, and then the gear plate 23 can be driven to rotate through the gear. At this time, the different brushes 24 on the surface of the gear plate 23 can be rotated toward the position directly below the electric hydraulic rod 21. At this time, the brush 24 can be moved down as a whole through the compression of the electric hydraulic rod 21, so that its bottom is in contact with the non-woven roller, so that lines can be left on the surface of the non-woven roller. Then, through the continuous movement of the moving platform 12 and the detection of the pressure sensor 13 and the use of different brushes 24, different line segments can be left at different positions on the surface of the non-woven roller. Subsequent personnel can clearly judge whether it is in a dynamic balance state and an area without dynamic balance by observing whether there are line segments on the surface of the non-woven roller and the color difference of the line segments at different positions, which is convenient for subsequent personnel to use and improves the overall practicality. The device as a whole has the advantages of high detection intuitiveness, detection distinction, and strong practicality.
