During the process of entering and leaving frame body 1, the workpiece contacts dust curtain 5 and drives dust curtain 5 to move. Under natural conditions, the bottom end of dust curtain 5 contacts the surface of conveying belt 2, preventing dust in frame body 1 from spreading to the external environment through both ends of frame body 1.

[0024] As shown in Figure 1 , the adjacent two dust curtains 5 are in close contact, and the side wall of the outermost dust curtain 5 is in close contact with the inner wall of frame body 1, so as to ensure the dustproof effect of dust curtain 5. One end of collecting roller 4 extends to the side of side plate 3 away from dust curtain 5, which facilitates the rotation of collecting roller 4 by the staff.

[0025] In further preferable embodiments of the utility model, as shown in Figure 4 The driving part 7 includes two support plates 71 fixedly connected to the top of the rack body 1, a top shell 72 fixedly connected to the top of the two support plates 71, a sliding bar 73 slidingly arranged in the lower half of the top shell 72, a rough pressing plate 74 fixedly connected to the bottom of the sliding bar 73, the bottom surface of the rough pressing plate 74 being attached to the outer circumferential surface of the collecting roller 4, a moving plate 75 fixedly connected to the top of the sliding bar 73, two electric push rods 76 fixedly connected to the inner bottom wall of the top shell 72, the output ends of the electric push rods 76 being fixedly connected to the bottom of the moving plate 75, and a linkage part 77 arranged above the moving plate 75.

[0026] In the present embodiment, in the initial state, the rough pressing plate 74 tightly presses against the outer circumferential surface of the collecting roller 4, the bottom surface of the rough pressing plate 74 is rough, and the outer circumferential surface of the collecting roller 4 located directly below the rough pressing plate 74 is also rough. Therefore, in the initial state, the collecting roller 4 does not rotate.

[0027] When the staff wants to replace the dust screen 5, the electric push rods 76 are driven to work, the moving plate 75 is driven to move upwards, the sliding bar 73 and the rough pressing plate 74 are driven to move upwards by the moving plate 75, and the rough pressing plate 74 is separated from the corresponding collecting roller 4.

[0028] In further preferable embodiments of the utility model, as shown in Figure 3 The cutting part 8 includes a bottom shell 81 fixedly connected to the inner bottom wall of the rack body 1, a first piston 82 slidingly arranged in the bottom shell 81, a cutting knife 83 fixedly connected to one side of the first piston 82, the cutting knife 83 partially slidingly passing through the inner side wall of the bottom shell 81, a limiting plate 84 fixedly connected to the inner top wall of the rack body 1, and the dust screen 5 passing between the cutting knife 83 and the limiting plate 84.

[0029] In the present embodiment, the first piston 82 is fully attached to the inner wall of the bottom shell 81, and fluid cannot pass through the first piston 82. In the initial state, the cutting knife 83 does not contact the dust screen 5, and one side of the dust screen 5 is attached to the limiting plate 84.

[0031] In the embodiment, the top shell 72 is filled with hydraulic oil above the second piston 771, and the flow pipe 773 and the bottom shell 81 are filled with hydraulic oil on the side of the first piston 82 close to the flow pipe 773. After the electric push rod 76 drives the moving plate 75 to move upward by a distance, the moving plate 75 contacts the second piston 771, drives the second piston 771 to move upward, the spring 772 is compressed, the second piston 771 drives the first piston 82 to move through the hydraulic oil, and the first piston 82 drives the cutting knife 83 to pass through the dust screen 5 to cut the dust screen 5.

[0032] After the dust screen 5 is cut, the electric push rod 76 is retracted, the moving plate 75 moves downward until the second piston 771 returns to the initial position and is in a natural state, at this time, the first piston 82 also returns to the initial position, and the cutting knife 83 returns to the initial position. At this time, the rough pressing plate 74 is still located above the collecting roller 4, the staff can rotate the collecting roller 4 to release the dust screen 5 wound on the outer periphery of the collecting roller 4 until the bottom surface of the dust screen 5 contacts the surface of the conveying belt 2, and then the electric push rod 76 continues to retract to the initial position, the moving plate 75 returns to the initial position, and the rough pressing plate 74 tightly presses the collecting roller 4 to prevent the collecting roller 4 from rotating again.

[0033] In a further preferred embodiment of the utility model, as shown in Figure 3 The limiting plate 84 is provided with an avoiding opening 85 on the side close to the dust screen 5 and corresponding to the position of the cutting knife 83.

[0034] In the embodiment, when the cutting knife 83 cuts the dust screen 5, part of the cutting knife 83 is inserted into the avoiding opening 85 to prevent the cutting knife 83 from being damaged due to collision between the cutting knife 83 and the limiting plate 84.

[0035] The embodiments of the specific embodiment are preferred embodiments of the utility model, and are not limited to the protection scope of the utility model, so that: equivalent changes made according to the structure, shape and principle of the utility model should be covered in the protection scope of the utility model.
