[0002] In the production process of medical non-woven fabrics, a large amount of static electricity will be generated due to dry weather and insufficient air humidity. If the static electricity is not handled, it may cause problems such as dust adsorption, flying flowers, and cloth strip entanglement, making it impossible to carry out production work normally and reducing production efficiency.

[0003] According to the existing Chinese patent CN 213991119 U, a non-woven fabric static elimination device belongs to the field of static elimination technology, including: a support frame fixed on the non-woven fabric production equipment, used to support the entire device; a telescopic rod, arranged in the support frame; a lifting block, fixedly connected to the lower end of the telescopic rod; an electrode rod, arranged on the lifting block, and a discharge needle is arranged at the bottom; and a static elimination host connected to the electrode rod through a wire. The support frame includes two frames, which are fixed on both sides of the non-woven fabric. The electrode rod is arranged between the two support frames and fixedly connected to the lifting block. The telescopic rod drives the lifting block and the electrode rod to move up and down to adapt to non-woven fabrics of different thicknesses. The utility model has a simple structure and is easy to operate, and can effectively improve the production efficiency of non-woven fabrics.

The application has high practicality, and the length of the device can be adjusted according to production needs. A suitable electrostatic ion rod 5 can be selected to achieve effective cost savings.

[0033] Figures 6 to 8A second embodiment is shown, and its main difference from the first embodiment is that: the clamping assembly includes a lower clamping strip 13, the protruding end of the square electric push rod 4 is fixedly connected to the lower clamping strip 13, the outer wall of the protruding end of the square electric push rod 4 is slidably connected to the upper clamping strip 14, the upper clamping strip 14 is located directly above the lower clamping strip 13, and a positioning assembly for positioning the lower clamping strip 13 and the upper clamping strip 14 is installed on the side of the lower clamping strip 13 away from the support frame 1, and semicircular grooves 15 are symmetrically opened on the side of the upper clamping strip 14 close to the lower clamping strip 13 and the side of the lower clamping strip 13 close to the upper clamping strip 14, and two corresponding semicircular grooves 15 on the upper clamping strip 14 and the lower clamping strip 13 form a cylindrical groove, and both ends of the electrostatic ion rod 5 are inserted into the cylindrical groove.

[0035] This application provides a clamping component and a positioning component on the clamping component, so that when the device is adjusted in length, it is convenient to replace electrostatic ion rods 5 of different lengths. When the electrostatic ion rod 5 is used for a long time and the static electricity removal effect is weakened, it can also be replaced more quickly, saving time and effort.

[0036] Working principle:

[0037] The device is set up on the medical non-woven fabric production equipment, so that the non-woven fabric passes under the electrostatic ion rod 5, and the four electrostatic ion rods 5 remove static electricity from the non-woven fabric passing through. The setting length of the device is adjusted according to production needs, and the device is set with two gear lengths.

[0038] When the electrostatic ion rod 5 is not installed, the length of the device is adjusted. First, the insertion rod 10 is pulled to stretch the first spring 11. When the insertion rod 10 leaves the socket 12, the lower connecting bar 6 can be dragged to change the installation length of the device, which can drive the first slide rail 2 to slide on the inner wall of the first slide bar 3, and the second slide rail 7 also slides on the inner wall of the second slide bar 9 until the insertion rod 10 is aligned with the other socket 12. The insertion rod 10 is released to make the first spring 11 rebound, and the insertion rod 10 enters the other socket 12, thereby fixing the adjusted length, and then the electrostatic ion rod 5 to be installed is selected according to the length.

[0039] First, the square electric push rod 4 is extended to its longest length, and two opposite square electric push rods 4 are selected in turn to install the electrostatic ion rod 5. The pull handle 20 is pulled in the direction away from the lower clamping strip 13, and the pull block immediately leaves the card slot 19. At this time, the upper clamping strip 14 can be pushed up. There is a large friction force between the upper clamping strip 14 and the outer wall of the extended end of the square electric push rod 4. After the upper clamping strip 14 is pushed up, the friction force between its inner wall and the outer wall of the extended end of the square electric push rod 4 ensures that the upper clamping strip 14 is pre-positioned at the top, and then the two ends of the two electrostatic ion rods 5 are placed on the lower clamping strip 13 in turn. The inner wall of the semicircular groove 15 is pushed downward, and then the upper clamping strip 14 is pushed downward to close the upper clamping strip 14 and the lower clamping strip 13. During the closing process, the upper clamping strip 14 will push the inclined surface at the top of the clamping strip 18 to make the clamping strip 18 slide away until it is completely closed. The spring pulls the clamping strip 18 into the clamping slot 19, and the upper clamping strip 14 and the lower clamping strip 13 are positioned to position the electrostatic ion rod 5. After the four electrostatic ion rods 5 are installed, the square electric push rod 4 can be used to adjust the height of the electrostatic ion rod 5. The device is set up on the non-woven fabric production equipment and the electrostatic ion rod 5 is turned on for use.
