[0019] As Figure 4 , Figure 5 Indicated, the dust collection cover 55 is provided as horn type structure;The dust collection cover 55 of horn type structure can expand the range of dust collection, in the working process of pair roller machine cutting cutter, can more effectively capture the dust generated, thereby improve the collection efficiency of dust near cutting cutter.

[0020] The filter layer 52 is provided as PTFE microporous membrane material;PTFE microporous membrane material filter layer has good filtering performance, can effectively filter out small dust particles.

[0021] As Figure 2 , Figure 3 , Figure 4 ,Figure 5 , Figure 6 As shown in the drawings, the workbench 7 is provided with a reciprocating mechanism 10, which comprises a screw rod 101, guide rods 102, a motor 103, a sliding block 104, a connecting plate 105 and a sensor 106. The screw rod 101 and the guide rods 102 are rotatably installed on the workbench 7, and the two guide rods 102 are located on the two sides of the screw rod 101. The motor 103 is installed on the side wall of the workbench 7, and the screw rod 101 is in transmission connection with the output end of the motor 103. The sliding block 104 is slidably installed on the screw rod 101 and the guide rods 102. The bottom end of the connecting plate 105 is connected with the sliding block 104 on the guide rod 102, and the top end is connected with the supporting plate 4. The sensor 106 is installed on the front and rear ends of the workbench 7. The motor 103 and the sensor 106 are in electrical connection with the controller 6. The position of the sliding block 104 is controlled by the motor 103, so as to realize the adjustment of the position of the dust collection mechanism 5. The guide rods 102 provide stable guiding action for the movement of the sliding block 104. When the dust collection mechanism 5 moves with the sliding block 104, it can ensure that the dust collection mechanism 5 moves along the predetermined track, avoids affecting the dust collection effect due to shaking or deviation, and ensures that the dust collection mechanism 5 stably works near the cutter opening. The sensor 106 can detect the limit position of the dust collection mechanism 5. When the dust collection mechanism 5 moves to the front and rear ends of the workbench 7, the sensor 106 transmits the signal to the controller 6, and the controller 6 can control the motor 103 to stop running or change the running direction.

[0022] Working process:

[0023] The movement of the material belt 8 is started, and the material belt 8 moves on the workbench 7 in a set direction and approaches the cutter 9. When the material belt 8 reaches the cutter 9, the cutter 9 starts the cutting operation on the two side edges of the material belt 8. During the cutting process, the fan 51 of the dust collection mechanism 5 is started to work by the controller 6, and the fan 51 generates suction force. The air containing the corner filaments and material powder is sucked from the dust collecting cover 55 and transmitted to the air inlet of the fan 51 through the dust conveying pipe 54. Since the dust collecting cover 55 is arranged in a horn type structure, the dust collection range is increased and the dust collection efficiency is improved. After the air passes through the fan 51, it flows to the air outlet. When the air passes through the filtering layer 52 of the PTFE microporous membrane material at the air outlet, the dust is blocked by the filtering layer 52, and the clean air is discharged through the air outlet, so that the dust cannot fall on the workbench again or enter the next process. The dust collection mechanism 5 is installed on the supporting plate 4, the supporting plate 4 is installed on the sliding rail 1 through the pulley 2, and the pulley 2 is limited by the limit block 3 on both sides. This structure can flexibly adjust the position of the dust collection mechanism 5 according to the actual working position of the cutter 9, so as to ensure that the dust collecting cover 55 is always located at the best dust collection position. For example, if the position of the cutter 9 needs to be adjusted to adapt to the cutting of material belts 8 of different specifications, the dust collection mechanism 5 can also be adjusted in position accordingly to ensure the dust collection effect. The protective shell 53 is detachable, and the filtering layer 52 is located inside the protective shell 53. This makes the maintenance and replacement of the filtering layer 52 very convenient. When the filtering layer 52 accumulates a lot of corner filaments and material powder after being used for a period of time, affecting the dust collection efficiency, the protective shell 53 can be easily opened to clean or replace the new filtering layer 52, ensuring the long-term effective operation of the filtering layer 52.

[0024] When the material belt 8 is cut, the operator removes the limit block 3 from the sliding rail 1, and then starts the reciprocating motion mechanism 10 through the controller 6. After receiving the instruction, the motor 103 starts to work, drives the screw rod 101 to rotate, and the sliding block 104 slides on the screw rod 101 and the guide rod 102. The sliding of the sliding block 104 drives the supporting plate 4 to move through the connecting plate 105, so as to realize the overall movement of the dust collection mechanism 5 and realize the dust collection operation of the whole workbench 7. The sensors 106 are installed at the front and rear ends of the workbench 7 to monitor the position and motion state of the dust collection mechanism 5 in real time. The sensors 106 transmit the monitored information to the controller 6, and the controller 6 intelligently controls the operation of the motor 103 according to the position and motion state of the dust collection mechanism 5. The design of the reciprocating motion mechanism 10 enables the dust collection mechanism 5 to cover a larger working area, further improving the dust collection effect.

[0025] Finally, it is explained that the above preferred embodiments are only used to illustrate the technical solutions of the present application and are not limited, although the present application has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present application.
