The control plate is arc-shaped, and a plurality of rollers are arranged in a circular array on one side of the control plate.

[0008] Preferably, linkage plates are rotatably provided on the front and back sides of the force-bearing block, and the top and bottom of the linkage plates are rotatably connected to the top and bottom of the movable cavity. When the force-bearing block is subjected to force on one side, the two linkage plates can be controlled to rotate inward and clamp.

[0009] Preferably, a brake frame is rotatably provided on one side of the front face of the linkage plate, the front face of the brake frame penetrates the housing and extends to the outside of the housing, and a brake plate is provided on the front face of the brake frame, which is also arc-shaped.

[0015] Compared with the prior art, the technical solution of the present invention has the following advantages: (1) A protective cover is provided around the spindle, which can protect the front and back and the left open position of the spindle, and implement multi-directional protection for the spindle without affecting the normal line-discharging operation of the spindle. The horizontal adsorption airflow generated when the spindle rotates can be converted into an upward exhaust airflow through the cooperation between the air inlet shell, the air outlet block and the air duct. If someone approaches to check the thread head on the spindle, the hair or clothes of the person close to the spindle can be blown upward to prevent the hair or clothes from being adsorbed and entangled by the high-speed rotating spindle and causing accidents. The air inlet shell is used to collect the airflow generated during high-speed rotation, and the air duct is used to redirect the collected airflow to a parallel position. When the redirected airflow passes through the air outlet block with a smaller outlet, it will generate a larger wind force due to the faster flow rate. The wind force can change the original rotating airflow and make it flow upward. An observation window is provided on the protective cover, which will not affect the user's normal observation of the winding drum on the spindle; (2) A fixed structure is also provided at the bottom of the protective cover. The fixed structure and the protective cover can form a dual-purpose cover. Under normal conditions, the airflow can be changed to prevent hair from being entangled. When the protective cover is moved, the fixed structure at the bottom of the protective cover can stop the spindles, so that the user can maintain or observe one of the spindles more carefully. Since one spindle and one protective cover are used on the abortion line, the normal operation of other spindles will not be affected when one spindle is stopped, and a separate control effect is achieved. The push wheel provided on the outer shell can temporarily make the tangent belt leave the tangent belt shaft. The spindle that loses the power source will be clamped by the brake plate and stop rotating. The push wheel itself is provided with a limit spring, which plays a buffering role when the push wheel pushes the tangent belt and will not directly push it rigidly to cause damage to the tangent belt; (3) The baffle is also provided with a movable plate and a threaded rod that can adjust the front and rear position and the upper and lower height of the shield. The user can freely adjust it according to actual use needs, which greatly increases the overall adjustability of the device. The baffle is also provided with a connecting plate, which can connect several separate baffles together to form a whole, making it more convenient for the user to open and close the baffle. When not in use, the baffle can also be rotated to lay flat and pushed into the storage box, which is convenient for the user to replace the spindle or thread without obstruction.

[0027] Slide rails 17 are provided on the front and rear sides of the bottom of one side of the baffle 9, and a limit plate 18 is slidably provided between the opposite sides of the two slide rails 17. A handle is provided on one side of the limit plate 18, and the limit plate 18 is adapted to the top block 20. Threaded holes are provided on both sides of the top of the front side of the baffle 9 and on both sides of the bottom. A connecting plate 13 is provided on one side of the baffle 9, and fixing screws are penetrated on both sides of the connecting plate 13, and the fixing screws are adapted to the threaded holes.

[0028] A through groove is provided in the middle of the baffle 9, and sliding grooves are provided on the front and rear sides of one side of the baffle 9. A slider is provided in the sliding groove. A movable plate 10 is slidably provided on the baffle 9. Limiting screws are passed through the front and back sides of the movable plate 10. The limiting screws are adapted to the slider, and a threaded rod 16 is passed through one side of the movable plate 10.

[0029] A connecting block 11 is rotatably provided on one side of the threaded rod 16 , a rotating shaft 19 is rotatably provided on one side of the connecting block 11 , one side of the rotating shaft 19 is fixedly connected to one side of the shield 1 , and a rotating seat 15 is provided on the other side of the threaded rod 16 .

[0030] The working principle and use process of the present invention are as follows: when in use, the user first slides the baffle 9 out of the storage seat 6, and after sliding it out, the baffle 9 is turned upward 90° with the rotation connection with the slide plate 21 as the center of the circle. After rotation, hold the handle to move the limit plate 18 downward along the slide rail 17 until the limit plate 18 covers the top block 20, so that the baffle 9 can be kept upright. When it is needed to be stored later, it can also be stored in the same way. When several baffles 9 are used together, the cooperation between the limit screws and the connecting plate 13 can make several baffles 9 form a whole for easy use. After setting the baffle 9, the user places the winding drum on the spindle 2, and adjusts the shield 1 to The corresponding position can be adjusted by moving the movable plate 10 up and down along the slide slot when the height is adjusted. When the position between the shield 1 and the spindle 2 needs to be adjusted, the rotating seat 15 is rotated. The rotating seat 15 controls the shield 1 to move left and right to adjust the position through the threaded rod 16. When the angle needs to be adjusted, it can be controlled by the rotating shaft 19. After all adjustments are made, the tangential belt on the machine can be started. After the tangential belt is running, it will control the spindle 2 to rotate at high speed through the friction between the tangential belt shaft 4. The lateral airflow generated by the rotation of the spindle 2 will be absorbed by the air inlet shells 3 on three sides of the shield 1. The airflow absorbed by the air inlet shell 3 will enter the air duct 22, and will be discharged outward from the air outlet block 12 after being redirected in the air duct 22. When the airflow is discharged, due to the air outlet block 12 A smaller air outlet will increase the speed of the airflow so that the airflow discharged by the air outlet block 12 is greater than the airflow generated when the spindle 2 rotates, which can destroy the original horizontal rotating airflow and make the overall airflow flow upward. In this way, when the user lowers his head to observe, he can avoid the hair, clothes, etc. being sucked into the horizontal rotating airflow and causing entanglement and accidents. When the user finds that there is a problem with the winding drum on the spindle 2 and needs further observation or needs to stop, the threaded rod 16 can be used to control the further movement of the shield 1. As the shield 1 continues to move, the push wheel 7 on the bottom shell 804 will first contact the dragon belt, and as it continues to move, the push wheel 7 will drive the dragon belt to move a little distance backward. This distance makes the dragon belt detach from the dragon belt shaft 4. The control plate 805 that receives the pressure will drive the force block 808 to move to one side through the control rod 802 and squeeze the reset spring 809. The force block 808 moves backward and drives the two linkage plates 807 to move inward with the rotating connection point inside the shell 804 as the center to form a clamping shape. The linkage plate 807 drives the brake plate 801 to clamp and stop the tangential belt shaft 4 through the brake frame 806, so that the user can operate one of the spindles 2 separately without stopping the entire production line. After the operation, the shield 1 returns to its original position, and the tangential belt continues to connect with the tangential belt shaft 4 to restore the rotation of the spindle 2.
