Description

Technical Field

[0001] The utility model relates to the technical field of fiber tube testing, in particular to an electrostatic property measuring device. Background Art

[0002] The static electricity property of untwisted coarse fibers is measured by cutting the fibers into a specified length and then passing the fibers through a stainless steel plate. The static electricity property of the fibers is obtained by measuring the amount remaining on the stainless steel plate.

[0003] At present, when conducting measurements, there are high requirements for the indoor environment, such as whether there is wind. When the indoor air flows faster, it will affect the measurement results. In addition, when collecting the adsorbed fiber filaments, some of the fiber filaments are likely to fall off, thus causing large errors. Utility Model Content

[0004] The utility model provides an electrostatic property measuring device to solve the above-mentioned deficiencies of the prior art, and can conduct an electrostatic adsorption test in a relatively closed space, thereby preventing the flow of indoor air from affecting the test result, and has strong practicality.

And the movable rod arranged on the collection box is a screw, and this arrangement method facilitates the operator to completely remove the collection box from the discharge outlet.

[0007] Furthermore, a rectangular feed tube is provided in the feed port, the lower end of the rectangular feed tube is inclined, and the upper end of the rectangular feed tube is provided with a limit frame.

[0008] Furthermore, a cover plate is provided at the discharge port, and the setting of the cover plate can further ensure the test environment in the box.

[0009] Furthermore, the guide plate has an L-shaped structure to improve the guiding effect.

[0010] Furthermore, the support frame includes a pair of support plates, the upper end of the support plate is provided with an inclined support plate, one side of the inclined support plate is opened to form a U-shaped groove, a locking screw is provided in the U-shaped groove, and the locking screw is arranged on the inclined plate.

[0021] like Figure 1~Figure 5 As shown, an electrostatic property measuring device comprises a box body 1, a feed port 12 is provided at the upper end of the box body 1, a discharge port 10 is provided at the lower end of the box body 1, and a cover plate is provided at the discharge port 10. Transverse holes 11 are provided at the lower ends of both sides of the box body 1, and inclined holes are provided on both sides of the box body 1, and guide plates 60 are provided on both sides of the inclined holes, and the guide plates 60 are L-shaped structures.

[0022] An inclined plate 34 is arranged obliquely in the box body 1. The inclined plate 34 is a steel plate. The inclined plate 34 is installed in the box body 1 through a pair of support frames. The support frames include a pair of support plates 3. An inclined support plate 30 is arranged at the upper end of the support plate 3. A U-shaped groove 31 is formed in an opening on one side of the inclined support plate 30. A locking screw 32 is arranged in the U-shaped groove 31. The locking screw 32 is arranged on the inclined plate 34. The inclined support plate 30 is made of insulating material.

[0023] A movable rod 40 is inserted into the transverse hole 11 , and a collecting box 6 is provided at the inner end of the movable rod 40 .

[0024] An inner rod 41 is inserted into the inclined hole, a fastener 4 is provided at the inner end of the inner rod 41 , and the fastener 4 is sleeved on the guide plate 60 . A concave plate 44 is provided at the inner end of the inner rod 41 , and a brush 45 is provided on the concave plate 44 .

[0025] A rectangular feed pipe 2 is provided in the feed port 12 . The lower end of the rectangular feed pipe 2 is inclined, and a limit frame 20 is provided at the upper end of the rectangular feed pipe 2 .

[0026] In this embodiment, when conducting the adsorption test, the brush 45 is moved to the upper end of the box body 1, and the rectangular feed tube 2 is inserted into the feed port 12. After the insertion, there is a certain distance between the lower end of the rectangular feed tube 2 and the inclined plate 34, and the collecting box 6 is moved to the bottom of the inclined plate 34. Then, the fiber filaments cut by the short cutter will enter the box body 1 through the rectangular feed tube 2. When the fiber filaments are cut by the short cutter, the fiber filaments will carry static electricity due to friction. When the fiber filaments pass through the inclined plate 34, the fiber filaments will be adsorbed on the inclined plate 34 due to static electricity. When the fiber filaments move downward, the friction between them and the inclined plate 34 will increase the static electricity potential, so they are finally adsorbed on the inclined plate 34. When the amount of fiber filaments entering reaches a predetermined amount, the cutting of the fiber filaments is stopped, and the rectangular feed tube 2 is pulled out, and the collecting box 6 is removed at the same time, and then the brush 45 is moved to clean the fiber filaments on the inclined plate 34 into the collecting box 6. After completion, the limit of the collecting box 6 by the movable rod 40 is cancelled, and the fiber filaments are weighed, and finally the electrostatic properties are obtained. The less the mass of the adsorbed fiber filaments, the stronger the anti-static ability, and vice versa.

[0027] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Obviously, those skilled in the art can make various changes and modifications to the utility model without departing from the spirit and scope of the utility model. Thus, if these modifications and variations of the utility model fall within the scope of the claims of the utility model and their equivalents, the utility model is also intended to include these modifications and variations.
