[0028] like Figures 1-4 As shown in the figure, this embodiment provides a cotton nip and short fiber measuring instrument, including a measuring box 1 and two symmetrical connecting plates 2 on both sides of the upper end face of the measuring box 1. A laser sensor 3 is provided in the middle of the upper end of the two sets of connecting plates 2. A motor 4 is provided on one side of the outer wall of the connecting plate 2. A bidirectional lead screw 5 is connected to the output end of the motor 4. Two sets of symmetrical ball screw sleeves 6 are sleeved on the outer wall of the bidirectional lead screw 5. A fixing component 7 is provided on one side of the outer wall of the ball screw sleeve 6.

[0029] The end of the bidirectional lead screw 5 away from the motor 4 moves through the connecting plate 2 and is rotatably connected to the inner wall of the connecting plate 2.

[0030] The fixing component 7 includes a fixing plate 71 fixedly disposed on one side of the outer wall of the ball screw sleeve 6. Two sets of first slide rods 72 are fixedly disposed inside the fixing plate 71. A slide plate 73 is movably sleeved on the upper outer wall of the first slide rod 72. A receiving plate 74 is fixedly sleeved on the lower end of the first slide rod 72 located on the slide plate 73.

[0031] Voltage plates 75 are fixedly provided at the ends of the sliding plate 73 and the receiving plate 74 that are close to each other.

[0032] The laser sensor 3 also includes a fixed sleeve 77 fixedly disposed on the upper surface of the slide plate 73. A turntable 78 is interlocked in the inner wall of the fixed sleeve 77. A bolt 76 is fixedly disposed on the upper end of the turntable 78. The bolt 76 moves through the fixed sleeve 77 and is threaded into the middle of the upper end of the fixed plate 71.

[0033] According to the length of the neps, the motor 4 drives the bidirectional screw rod 5 to rotate, and the two groups of ball screw sleeves 6 move away from or close to each other. When the distance between the two groups of fixed plates 71 is close to the length of the neps, the sliding sleeve 10 slides along the second sliding rod 9 during the process, increasing the stability of the fixed plate 71 during the movement process. The two ends of the neps are placed on the upper end of the voltage sheet 75 on the upper end of the receiving plate 74, and then the bolt 76 is turned down. The bolt 76 rotates downward along the fixed plate 71, and at the same time, the bolt 76 drives the rotating disc 78 to rotate along the inner wall of the fixed sleeve 77, and the rotating disc 78 drives the fixed sleeve 77 to move downward, so that the sliding plate 73 moves close to the lower end of the receiving plate 74. The two groups of voltage sheets 75 fix the neps, so that the neps of different lengths can be fixed conveniently, and the subsequent opening operation is facilitated. By electrifying the voltage sheet 75, the length of the fiber is determined by measuring the voltage of the fiber at both ends through the voltage sheet 75 at both ends.

[0034] As Figures 1-4 As shown, the measuring box 1 is provided with an opening assembly 8 in the inner cavity. The opening assembly 8 includes a ventilation disc 81 fixedly inserted into the middle of the upper end face of the measuring box 1. A plurality of air holes 82 are uniformly arranged on the inner wall of the ventilation disc 81 from top to bottom. A wind collecting cover 83 is fixedly arranged at the lower end of the ventilation disc 81 in the inner cavity of the measuring box 1. A high-speed fan 84 is fixedly arranged at the bottom end of the inner cavity of the measuring box 1. The outlet end of the high-speed fan 84 is connected with an outlet pipe 85.

[0035] The wind collecting cover 83 is in the shape of a circular truncated cone, and the radius of the upper end face of the wind collecting cover 83 is smaller than the radius of the lower end face of the wind collecting cover 83.

[0036] The end of the outlet pipe 85 away from the high-speed fan 84 is located in the wind collecting cover 83.

[0037] After the neps are fixed, the high-speed fan 84 is started, and high-speed airflow is blown into the wind collecting cover 83 through the outlet pipe 85 and blown out through the air holes 82 at the upper end of the ventilation disc 81. The high-speed airflow blown out of the air holes 82 can open the cotton fibers, avoid the fibers being too dense, and increase the amount of light blocked by the fibers, thereby causing certain interference to the determination of the number of neps and the content of short fibers. The design of the wind collecting cover 83, which is narrow at the top and wide at the bottom, can make the airflow entering the wind collecting cover 83 more concentrated to one end of the ventilation disc 81, so that the airflow is more concentrated and the blowing effect is better. After blowing, the laser sensor 3 can be started to generate corresponding signals according to the passing cotton layer, and the content of neps in the cotton layer and the classification of neps according to size and category can be obtained by processing these signals.

[0038] It should be understood that the use of these embodiments is by way of illustration only and is not intended to limit the scope of the present application. In addition, it should also be understood that, after reading the technical content of the present application, those skilled in the art can make various modifications, modifications and / or variations to the present application, and all of these equivalent forms also fall within the protection scope defined by the claims attached to the present application.
