[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This sliver-tearing device uses a support frame inside the cotton conveying fan box to fix the drive motor in the middle of its front side. During operation, four brackets extending from the support frame further stabilize the drive motor. The drive motor rotates its drive shaft, causing the fan to rotate and output air through the outlet. The drive motor has a power of 3KW, an output air volume of 3600m³ / h, and an air pressure of 1000Pa. The air duct is formed inside the air outlet box, and material is discharged through the air outlet on the front side of the air outlet. A nylon mesh bag is fitted outside the air outlet, and a fixing outer ring is installed on the outer part of the nylon mesh bag that fits over the air outlet. The nylon mesh bag is adjusted by rotating a knob on the outer side of the fixing outer ring. The nylon mesh bag can be fixed or loosened and removed. The mounting base plate on the left side of the air box and the fixing nut fix the connecting pipe. A bend is installed on the left side of the connecting pipe. The combing strip is put into the air box through the bend. The fan inside the cotton conveying fan box is driven by the motor. The high-speed rotation of the fan creates a rotating airflow and mechanical impact force. After the combing strip enters the air box, it will be directly hit by the rotating fan blades. At the same time, it will be torn and broken by the high-speed airflow. Finally, it will be decomposed into spare raw materials with a length of about 20 cm and discharged into the nylon mesh bag through the air outlet. This makes the equipment more efficient than manual operation. The torn strips are of uniform length, which is convenient for subsequent use and will not entangle the hands, ensuring smooth production.

[0016] 2. This sliver tearing and combing device is fixedly installed to the connecting pile by the fixed column legs below the air box and the cotton conveying fan box. The device can be moved by the casters below the connecting pile. After being moved to the designated work site, the electric push rods on the fixed plates on the left and right sides of the connecting pile are operated to move the push rods up and down axially, pushing the fixed outer frame below the push rods to the ground and lifting the device so that the casters are off the ground, making it more convenient to place or move the device.

The cotton conveying fan box 2 has an output port 7 in the middle of the front side, and the fan 6 is located inside the output port 7. The drive shaft 5 of the drive motor 4 extends forward along the axis and is coaxial with the output port 7. The air outlet box 1 has an air outlet 8 in the middle of the front side. A nylon mesh bag 9 is fitted on the outside of the air outlet 8. The nylon mesh bag 9 has a density of 200 mesh and a total capacity of 200 kg. A fixing outer ring 10 is wrapped around the outside of the nylon mesh bag 9, and the fixing outer ring 10 is installed on the outer wall of the nylon mesh bag 9 outside the air outlet 8.

[0024] A tightening knob 11 is provided on the middle left side of the outer wall of the fixed outer ring 10. A mounting base plate 12 is provided on the middle left side of the air outlet box 1. Fixing nuts 13 are evenly distributed around the outer perimeter of the mounting base plate 12. A connecting pipe 14 is provided on the middle left side of the mounting base plate 12, and the connecting pipe 14 is located in the middle of the inner side of the fixing nut 13. A bend 15 is provided on the left side of the connecting pipe 14. The bend 15 is a φ300mm×45° standard elbow. The angle between the center line of the elbow and the axis of the connecting pipe 14 is exactly 45°. Fixed column legs 16 are provided on the left and right sides below the air outlet box 1 and the cotton conveying fan box 2.

[0025] Connecting posts 17 are evenly distributed at the four corners of the bottom outer side of the fixed column leg 16. Universal wheels 18 are installed below the connecting posts 17. Fixing plates 19 are installed horizontally on the left and right sides of the connecting posts 17. An electric push rod 20 is installed in the middle of the upper part of the fixing plate 19. The axis of the electric push rod 20 is parallel to the center line of the fixed column leg 16. A push rod 21 is installed below the electric push rod 20. A fixed outer frame 22 is installed below the push rod 21. The push rod 21 of the electric push rod 20 passes through the fixing plate 19 and connects to the top of the fixed outer frame 22. There are two sets of electric push rods 20 that move synchronously. The fixed outer frame 22 is located outside the universal wheels 18.

[0026] Working principle: When the tearing and combing device is needed, the equipment is moved to the working location by using the casters 18 installed on the connecting piles 17 below the fixed column legs 16 of the air outlet box 1 and the cotton conveying fan box 2. After moving to the working location, the electric push rods 20 on the fixed plates 19 on both sides of the connecting pile 17 are activated and their push rods 21 are pushed axially downwards, pushing the fixed outer frame 22 to the ground and lifting the casters 18 off the ground, making the equipment more stable. When the equipment needs to be moved, its push rods 21 are retracted upwards. The outer frame 22 is fixed and the casters 18 are placed on the ground for movement. After the equipment is placed, the bent pipe 15 is installed and fixed to the connecting pipe 14 on the left side of the air outlet box 1. The connecting pipe 14 is fixedly connected to the air outlet box 1 by the mounting base plate 12 and the fixing nut 13, forming a passage. When in use, the drive motor 4 inside the cotton conveying fan box 2 is turned on, and the carding strip is put into the air outlet box 1 through the bent pipe 15. The operation of the drive motor 4 inside the cotton conveying fan box 2 causes the fan 6 to rotate. The high-speed rotation of the fan 6 forms a rotation. Due to airflow and mechanical impact, the combed strips are directly struck by the rotating fan blades after entering the air outlet box 1. Simultaneously, driven by the high-speed airflow, they are torn and broken down, ultimately decomposing into spare raw materials approximately 20 cm in length. These materials are then discharged through the air outlet 8 into a nylon mesh bag 9 for collection. The nylon mesh bag 9 has a density of 200 mesh and a total capacity of 200 kg. The nylon mesh bag 9 is fitted onto the outer wall of the air outlet 8 and secured by a fixing outer ring 10. It is tightened by rotating the tension knob 11, and loosening or untightening the tension knob 11 allows for... The collected nylon mesh bags 9 are removed and replaced with new ones. The support frame 3 inside the cotton conveying fan box 2 fixes the drive motor 4 in the middle of its front side. When the drive motor 4 is running, the four brackets extending from the support frame 3 fix it to prevent violent shaking. The operation of the drive motor 4 causes its transmission shaft 5 to rotate and drives the fan 6 to rotate accordingly. The drive motor 4 has a power of 3KW, an output air volume of 3600m³ / h, and an air pressure of 1000Pa. The output is more stable and the power is greater. The impact force generated by the rotation of the fan 6 is greater.

Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
