[0013] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work are within the protection scope of the present application.
[0014] Please refer to Figures 1-4The application provides a grid cloth guide device for carton board production, which comprises a rack 1, a deflection shaft 2, swing frames 3, a circular arc guide rail 4, a standby roll 5, a guide roll 6, a fixed platform 7, a placing plate 8, a guide rod 9, a rear pushing mechanism 10, a front pushing mechanism 20, a buffer sleeve group 30 and a stop mechanism 40. The rack 1 is a frame welded by square tubes. The deflection shaft 2 is arranged in the middle of the rack 1 through a bearing seat and is driven by a power mechanism. The swing frames 3 are arranged in pairs and are fixed at the two sides of the deflection shaft 2. The front ends of the swing frames 3 are provided with fixed grooves. The two ends of the circular arc guide rail 4 are fixed at the front side and the top of the rack 1. The top of the circular arc guide rail 4 is provided with a fixed groove. The circular arc guide rail 4 is matched with the swing frames 3. The standby roll 5 is placed in the fixed groove of the swing frame 3. The guide roll 5 is placed in the fixed groove of the circular arc guide rail 4. The fixed platform 7 is arranged on the upper side of the rack 1. The placing plate 8 is fixed at the front of the fixed platform. The guide rod 8 is fixed on the rack 1 below the guide roll 6 through a support. The rear pushing mechanism 10 is arranged at the rear of the fixed platform 7. The front pushing mechanism 20 is arranged at the front side of the fixed platform 7. The buffer sleeve group 30 is arranged at the rear side of the rack 1. The stop mechanism 40 comprises a stop cylinder 41 and a stop pressing frame 42. The stop mechanism 40 is arranged on the rack 1 at the rear of the fixed platform 7. The stop pressing frame 42 is fixed at the telescopic end of the stop cylinder 41.
[0015] In the normal production state, the standby roll 5 is placed in the fixed groove of the swing frame 3 and the guide roll 6 is placed in the fixed groove of the circular arc guide rail 4. At this time, the swing frame 3 is in a horizontal state. The end of the grid cloth strip in the standby roll 5 is pasted with adhesive tape and placed on the placing plate 8. The grid cloth strip of the guide roll 5 is sequentially wound around the guide rod 9, the rear pushing mechanism 10 and the buffer sleeve group 30. When the remaining amount of the guide roll 5 is insufficient, the end of the grid cloth strip slides out and is detected. The stop cylinder 41 of the stop mechanism 40 pushes the stop pressing frame 42 to lower the height and press the grid cloth strip. Due to the existence of the buffer sleeve group 30, the grid cloth strip of the rear equipment can be normally guided out and does not affect the normal processing of the subsequent equipment. After the end of the grid cloth strip slides out, it is pushed to the placing plate 8 by the rear pushing mechanism 10. The end of the guide roll 5 is first pressed to the front end of the standby roll 5. After the pressing, the rear pushing mechanism 10 returns to the initial position. At this time, the front pushing mechanism 20 performs the second pressing to further improve the firmness of the butt joint. After the butt joint is completed, the stop mechanism 40 releases the grid cloth strip for normal guiding and conveying. The tension of the buffer sleeve group 30 is released and returns to the initial state. The empty shaft of the guide roll 6 is quickly taken off by hand. At this time, the deflection shaft 2 drives the swing frame 3 to deflect under the drive of the power equipment until the standby roll 5 falls into the fixed groove of the circular arc guide rail 4 to become a new guide roll 6. A new standby roll 5 can be placed by hand. The end of the grid cloth strip in the standby roll 5 is pasted with adhesive tape and placed on the placing plate 8 for cyclic operation.
[0016] Further, the rear pushing mechanism 10 comprises a rear pushing cylinder 11, a rear moving seat 12, a swing arm 13, a rear pushing roller 14, a pressure spring 15, a supporting wheel 16 and a lifting guide rail 17. The rear pushing cylinder 11 is fixed on the frame 1 through a support. The rear moving seat 12 is fixed on the telescopic end of the rear pushing cylinder 11. The swing arm 13 is symmetrically arranged on both sides of the front end face of the rear moving seat 12 through a pin shaft. The rear pushing roller 14 is connected to the outer end of the swing arm 13 through a bearing seat on both sides. One end of the pressure spring 15 is fixed on the rear moving seat 12, and the other end is fixed on the outer end of the swing arm 13. The supporting wheel 16 is fixed on the outer side of the swing arm 13. The lifting guide rail 17 is fixed on the frame 1. The lifting guide rail 17 is matched with the supporting wheel 16, and the front end of the lifting guide rail 17 is a beveled surface.
[0017] In the normal feeding state, the rear pushing cylinder 11 is in the retracted state. Under the action of the supporting wheel 16 and the lifting guide rail 17, the rear pushing roller 14 is lifted and used as a guide roller. When the pushing is needed, the rear pushing cylinder 11 pushes the rear moving seat 12 to move forward. Since the front end of the lifting guide rail 17 is a beveled surface, after pushing, the supporting wheel 16 is released, and the pressure spring 15 pushes the swing arm 13 to swing downward, so that the rear pushing roller 14 pushes the butt joint of the mesh cloth strip on the placing plate 8. After the pushing is completed, the rear pushing cylinder 11 is retracted, and the rear pushing roller 14 is lifted again under the action of the supporting wheel 16 and the lifting guide rail 17.
[0018] Further, the front pushing mechanism 20 comprises a front pushing cylinder 21, a front moving seat 22, a swing frame 23, a front pressing roller 24 and a turnover cylinder 25. The front pushing cylinder 21 is fixed on the frame 1. The front moving seat 22 is fixed on the telescopic end of the front pushing cylinder 21 and is movably connected to the frame 1 through a slide rail. One side of the swing frame 23 is movably connected to one side of the front moving seat 22 through a pin shaft. The front pressing roller 24 is connected to the swing frame 23 through a bearing seat. The turnover cylinder 25 is movably connected to the front moving seat 22 through a pin shaft seat, and the telescopic end of the turnover cylinder 25 is movably connected to one end of the swing frame 23 through a pin shaft seat.
[0019] After the end of the mesh cloth strip in the standby roll 5 is pasted with adhesive tape and placed on the placing plate 8, the turnover cylinder 25 pushes the swing frame 23 to turn to the horizontal state, so that the front pressing roller 24 is pressed on the placing plate 8. After the rear pushing mechanism 10 pushes, the front pushing cylinder 21 is retracted to pull the front moving seat 22, so that the front pressing roller 24 pushes the butt joint again to improve the firmness. Before the swing frame 3 is deflected, the turnover cylinder 25 pushes the swing frame 23 to turn to the vertical state, so that the standby roll 5 is switched to the lead-in roll 6.
[0020] Further, the buffer sleeve group 30 comprises a fixed pulley seat 31 and a movable pulley seat 32, the fixed pulley seat 31 is fixed on the upper rear side of the frame 1, and at least two groups of pulleys 33 are uniformly arranged on the fixed pulley seat 31, the movable pulley seat 32 is arranged below the fixed pulley seat 31 and is supported by the bottom of the frame 1, and at least two groups of pulleys 33 are uniformly arranged on the movable pulley seat 32, and the scrim strips pass through the pulleys 33 in the fixed pulley seat 31 and the movable pulley seat 32 in sequence.
[0021] Since the scrim strips pass through the pulleys 33 in the fixed pulley seat 31 and the movable pulley seat 32 in sequence, when the front end of the scrim strips is fixed by the stopping mechanism 40, the tension of the scrim strips is increased, the movable pulley seat 32 is pulled to provide a position, and the normal export of the scrim strips of the rear-end equipment is completed, which does not affect the normal processing of the subsequent equipment. Further, a cutting mechanism 50 is arranged below the guide rod 9, the cutting mechanism 50 comprises a fixed knife 51, a movable knife 52 and a cutting cylinder 53, the fixed knife 51 is fixed on the frame 1 below the guide rod 9, the movable knife 52 is movably connected to the frame 1 through a pin shaft, the movable knife 52 is matched with the fixed knife 51, and the cutting cylinder 53 is movably connected to the frame 1 through a pin shaft seat, and the telescopic end of the cutting cylinder 53 is connected to the end of the movable knife 52 through the pin shaft seat.
[0022] By arranging the cutting mechanism 50 below the guide rod 9, the scrim strips are cut when the scrim strips of the guide-in roll 6 are less, the excess control at the butt joint is reduced, and thus the precision of the butt joint is ensured, because if the scrim strips of the guide-in roll 6 are released to the end, the length of the end is long, the end of the scrim strips is loose, and the precision of the butt joint is reduced; the movable knife 52 is pushed to rotate by the cutting cylinder 53, and when the movable knife 52 contacts the fixed knife 51, the scrim strips can be effectively cut, the length of the end is short and the end is in a tense state, the length of the end is accurately controlled, and the precision of the butt joint is improved.
[0023] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and variations can be made in these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
