Detailed Description

The present invention will be described in further detail with reference to specific examples.

Examples

As shown in fig. 1 to 5, the discharging structure for the dust-free cloth transverse cutting machine comprises a frame (not shown), and a pressing mechanism 1, a cutting mechanism 2 and a pulling mechanism 3 which are sequentially arranged on the frame along a feeding direction, wherein a supporting table 4 is arranged below the pulling mechanism 3.

As shown in fig. 1 and 3, the pressing mechanism 1 includes a fixed clamp plate 11, a movable clamp plate 12 that can be lifted up and down relative to the fixed clamp plate 11, and a first driving member 13 that drives the movable clamp plate 12 up and down. The fixed clamping plate 11 and the movable clamping plate 12 are used for fixing the rear part of the dust-free cloth 5 during blanking, and are loosened when the material pulling mechanism 3 needs to continue pulling, so that poor cutting of the dust-free cloth 5 caused by shaking of the mechanism is avoided. The first driving part 13 may be a cylinder, an electric cylinder or other linear driving part.

As shown in fig. 3, the blanking mechanism 2 includes a heating wire 21 perpendicular to a feeding direction, a lifting block 22 to straighten both ends of the fixed heating wire 21, and a second driving part 23 to drive the lifting block 22 to lift. When the pulling mechanism 3 has pulled the dust-free cloth 5 out of the predetermined length, the movable clamp 12 presses the other end of the dust-free cloth 5 against the fixed clamp 11, and then the second driving member 23 drives the pressing bar 24 and the heating wire 21 downward, and the heating wire 21 contacts the dust-free cloth 5 to cut it into sheets 51. The second drive member 23 may be a pneumatic cylinder, an electric cylinder or other linear drive member.

As shown in fig. 1 to 5, the drawing mechanism 3 includes a first moving member 31 provided on the frame, a fixed plate 32 driven by the first moving member 31 to move back and forth in the feeding direction, and a drawing unit 33 provided on the fixed plate 32, the drawing unit 33 includes a gripping unit 331 and a discharging unit 332, the gripping unit 331 includes a fixed grip 3311, a movable grip 3312 provided above the fixed grip 3311, and a third driving member 3313 driving the movable grip 3312 to move toward or away from the fixed grip 3311, the discharging unit 332 includes a swinging block 3321 for fixing the gripping unit 331 and a fourth driving member provided on the fixed plate 32 and driving the swinging block 3321 to swing, the swinging block 3321 has a gear portion 33211 thereon, the fourth driving member is a biaxial cylinder 3322 and a rack 3323 driven by the biaxial cylinder 3322, and the gear portion 33211 is engaged with the rack 3323. The swinging of the swinging block 3321 is realized by a rack and pinion transmission manner, so that the discharging unit 332 lowers the sheet 51 at a position closer to the pallet 4. During clamping, the first moving part 31 drives the material pulling component 33 to be close to the material pressing mechanism 1, the fixed clamping strip 3311 and the movable clamping strip 3312 clamp the front end of the dust-free cloth 5, at the moment, the fixed clamping plate 11 and the movable clamping plate 12 release the dust-free cloth 5, the clamping unit 331 keeps clamping, the dust-free cloth 5 is pulled out to a preset length, the dust-free cloth 5 is kept taut, the material cutting mechanism 2 is cut in place, the tail end of the sheet 51 falls, the clamping unit 331 releases the front end of the sheet 51, and the sheet 51 can be placed on the supporting table 4. The discharging structure can enable cut sheets 51 to be stacked on the supporting table 4 more orderly, avoids disorder of the sheets 51 and facilitates collection. The first moving member 31 may be a moving module. The third drive member 3313 may be a pneumatic cylinder, an electric cylinder, or other linear drive member.

As shown in fig. 2 to 5, a second moving part 41 is arranged on the frame 1 between the blanking mechanism 2 and the pulling mechanism 3, the second moving part 41 drives a supporting strip 42 capable of moving back and forth along the feeding direction, the height of the supporting strip 42 is positioned between the upper surface of the fixed clamping plate 11 and the upper surface of the supporting table 4, and the upper surface of the supporting strip 42 is a slope in the oblique feeding direction. When the heating wire 21 cuts off the dust-free cloth 5, the supporting strip 42 can support the tail of the sheet 51, and under the condition that the clamping unit 331 is kept to clamp the head of the sheet 51, the second moving part 41 drives the supporting strip 42 to move towards the side of the blanking mechanism 2, the slope structure of the supporting strip 42 can enable the sheet 51 to be leveled and then fall onto the supporting table 4, and finally the clamping unit 331 releases the front end of the sheet 51, so that the front sheet 51 and the rear sheet 51 can be basically stacked in order during continuous operation. The second moving member 41 may be a belt conveyor.

As shown in fig. 1 and 2, the fixing plate 32 is provided with a fifth driving part 34, and the fifth driving part 34 drives a pressing plate 35 capable of vertically moving under the fixing plate 32. When the fixing plate 32 moves above the sheet 51, the first moving part 31 stops the sheet 51 slightly, and presses the stacked sheet 51 by the pressing plate 35, so that the influence on the continuous pulling of the sheet 51 due to fluffiness is avoided. The fifth drive member 34 may be a pneumatic cylinder, an electric cylinder, or other linear drive member.

What has been described above is merely some embodiments of the present invention. It will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the spirit of the invention.
