The pipeline 30 communicates, and the pressing rod 20 is fixedly connected to the piston 28 .

Working process of the present invention is as follows:

The rotating handle 3 connected with the mainspring 4 is rotated, the mainspring 4 is tightened, and the conveyor belt 7 has a tendency to move from the first roller 1 to the second roller 5, and a blocking rod is inserted in the through hole, and the rotating handle 3 is against the On the stop bar, the first roller 1 has a tendency to rotate because of the potential energy of the mainspring 4, and the conveyor belt 7 on the first roller 1 has a movement tendency from the first roller 1 to the second roller 5. The cotton swab 6 has a tendency to move towards the direction of the second roller 5 along with the conveyor belt 7, but due to the blocking effect of the wedge block 17, the conveyor belt 7 remains motionless. Unclamp the L-shaped bent bar 10 of the pressing mechanism after pressing once, and the L-shaped bent bar 10 drives the slide block 9 to move downward, and then promotes the slide block 9 in the chute of the spring holder 13 to move downward, compressing the first spring 12. The pull wire 10 is loose, and the first magnet enters the through hole of the conveyor belt 7 due to the attractive force with the second magnet block 24, and pushes the cotton swab 6 out.

The bending part of the L-shaped curved rod 10 is connected with a trigger block 19 that hits the wedge block 17, thereby compressing the second spring 16, and the conveyor belt 7 moves toward the second roller 5 under the force of the mainspring 4.

The other end of the L-shaped curved rod 10 hits the pressing rod 20 on the water tank 21, and the pressing rod 20 moves the piston 28 in the water tank 21 downwards, and the water is sprayed from the water spray port 23 to the end of the cotton swab 6 to wet the cotton swab. The rear cotton swab 6 is taken out for animal hair removal. After the pressing rod is released, because the third spring 34 in the compressed state stretches gradually, the piston 28 moves upwards, and the gas enters the water tank 21 from the water outlet pipe 33 .

After the L-shaped bent rod 10 is released, the elastic force of the first spring 12 pushes the slider 9 to move up, and then pulls the pull wire 11 to move up. The pulling force is greater than the attraction force between the first magnet and the second magnet block 24. A magnet ejects from the through hole of the conveyor belt 7 and is fixed on the first magnet frame 15 .

The rebound time of the first spring 12 is shorter than the rebound time of the second spring 16. After a period of time after the first magnet is withdrawn from the through hole, the second spring 16 returns to the wedge-shaped block 17 against the wedge-shaped groove Inside.

In the processing device provided by the present invention, the pressing mechanism and the water spray mechanism are arranged on both sides of the conveyor belt 7, and the conveyor belt 7 moves under the drive of the roller, and the second roller is equipped with a spring, so it is a driving roller, and the conveyor belt 7 There are repeated wedge-shaped grooves with the same size and structure on the bottom surface of the conveyor belt. The cross-section of the wedge-shaped grooves is a right-angled triangle. scroll wheel. The pressing mechanism triggers the cotton swab delivery device and the water spray mechanism at the same time, which realizes the transmission and wetting of a large number of cotton swabs in the animal hair removal process, saves the time and workload of hair removal, and avoids skin damage caused by too slow hair removal and the use of dry cotton swabs , affecting the accuracy of the experiment.

The treatment device provided by the present invention was used in the animal hair removal test, and the three steps of transmission, ejection and wetting were simultaneously realized by pressing the same switch, which greatly reduced the degree of skin damage of mice, as shown in Figure 7 According to the results, one group is the wet cotton swab hair removal group, and the other two is the dry cotton swab hair removal group, and the results have significant statistical differences. Depilation with wet swabs resulted in significantly less skin damage in mice compared with depilation with dry swabs. Legend: n1=31, n2=6, the average value of damaged skin area/total hair removal area in group 1=0.002890893, the average value of damaged skin area/total hair removal area in group 2=0.192366167, P=5.4951E-12.
