Technical Field

[0001] The utility model relates to the technical field of PC film production lines, in particular to off-line edge material recovery equipment for PC lines. Background Art

[0002] PC film is the abbreviation of polycarbonate film. It is an amorphous, odorless, non-toxic, highly transparent, colorless or slightly yellow thermoplastic engineering plastic with excellent physical and mechanical properties. It has been widely used in various industries.

[0003] In the process of PC film production, the PC film pressed by the calender needs to be cut by a slitting machine. The cut PC film will produce some scraps that do not meet the specified size. The excess scraps will leave the production line and be recycled. The existing recycling equipment generally rewinds the film through a reel and pulverizes the scraps with a shredder. However, the film needs to be transported from the rewinding structure to the inside of the shredder. The transportation process will incur a certain time cost and is inefficient. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. This PC line off-line scrap recovery equipment installs an active rotating shaft above the second driven conveying shaft, and the active rotating shaft drives multiple cutters to rotate at high speed. The PC film passes through the second driven conveying shaft, the separation shaft, and the scrap winding shaft in turn. When the PC film passes through the upper surface of the second driven conveying shaft, it will be cut into a specified size by the cutter above the second driven conveying shaft and continue to be conveyed. The excess scrap film will enter the surface of the scrap winding shaft through the separation shaft, and will be transported to the inside of the crushing bin by the scrap winding shaft, and crushed by two crushing rollers. The crushed scrap film fragments will fall through the opening of the crushing bin, and will be pulled into the inside of the crushing bin for crushing by the cooperation of the two conveying rollers and the scrap winding shaft inside the crushing bin, which saves the time cost of transportation to a certain extent.

[0013] 2. This PC line off-line scrap recycling equipment drives the scrap winding shaft to rotate through the driving motor inside the motor protection shell, so as to reel up the scrap film. Since both ends of the fixed sleeve and the movable sleeve are slidably connected with the guide slide groove through the slider, the fixed sleeve and the movable sleeve will not rotate with the scrap winding shaft. When the scrap winding shaft needs to be replaced, it is only necessary to remove the motor protection shell from the outer end of the recycling bin and pull the scrap winding shaft out of the recycling bin through the through hole to replace the scrap winding shaft.

[0022] like Figures 1 to 4As shown, the PC line off-line edge material recovery equipment of this embodiment includes a recovery bin 1 and a PC film 20. The PC film 20 is a finished film pressed by a plastic device. The interior of the recovery bin 1 is lateral and rotatably connected to a second driven conveying shaft 7. The second driven conveying shaft 7 can rotate under the action of an external force. An active rotating shaft 3 is rotatably connected to the position above the second driven conveying shaft 7 located inside the recovery bin 1. The active rotating shaft 3 is connected to an external driving device. The driving device can select a common servo motor on the market. The active rotating shaft 3 is driven by the driving device to rotate at a high speed. A plurality of cutters 4 are installed on the surface of the active rotating shaft 3. The active rotating shaft 3 drives the plurality of cutters 4 to rotate at a high speed. The spacing between the plurality of cutters 4 can be adjusted according to the size of the PC film 20 to be cut. A separation shaft 8 is rotatably connected to the position of the second driven conveying shaft 7 located inside the recovery bin 1 at the lower left side. The separation shaft 8 is rotatably connected to the position of the separation shaft 8 under the action of an external force.

[0023] Specifically, a main material winding shaft 9 is rotatably connected to a position above the edge material winding shaft 10 located inside the recovery bin 1. The main material film 22 generated after the PC film 20 is cut passes through the second driven conveying shaft 7 and the separation shaft 8 in sequence and is wound up by the main material winding shaft 9. After being cut by the cutter 4, the main material film 22 that meets the specified size will pass through the separation shaft 8 and be towed and wound up by the main material winding shaft 9. One end of the main material winding shaft 9 is connected to a driving device, and is actively rotated under the drive of the driving device.

[0024] Furthermore, two first driven conveying shafts 2 are installed in the two recovery bins 1 at the lower right side of the second driven conveying shaft 7. Figure 2As shown, the horizontal position and the vertical position of the first driven conveying shaft 2 are inconsistent, and gradually approach the second driven conveying shaft 7. The second driven conveying shaft 7 plays a certain guiding role in the conveying of the PC film 20. Compared with laying the PC film 20 on the second driven conveying shaft 7, the conveying and guiding by the two first driven conveying shafts 2 can avoid the folding of the PC film 20 during the conveying process.

[0025] Furthermore, two guide ring mechanisms 14 are symmetrically installed on the surface of the scrap material winding shaft 10, and a motor protection shell 18 is installed at the outer end of the recovery bin 1. The output end of the driving motor inside the motor protection shell 18 passes through the recovery bin 1 and is connected to one end of the scrap material winding shaft 10. Since the scrap material film 21 is small in size, it is stacked too much on the surface of the scrap material winding shaft 10. When the thickness is thick, it is easy to fall off. The two scrap material films 21 can be pulled from the edge position of the scrap material winding shaft 10 to the center position through two symmetrically installed guide ring mechanisms 14, and the scrap material film 21 can be prevented from stacking on the surface of the scrap material winding shaft 10.

[0026] Furthermore, a fixed sleeve 17 and a movable sleeve 19 are respectively installed at both ends of the edge material winding shaft 10, and two parallel sliders 16 are symmetrically installed on the surfaces of the fixed sleeve 17 and the movable sleeve 19. The output end of the driving motor passes through the fixed sleeve 17 and is connected to the edge material winding shaft 10. One end of the movable sleeve 19 contacts the inner wall of the recycling bin 1. A conveying channel 12 is provided at the connection between the inside of the recycling bin 1 and the crushing bin 5. Two mutually parallel fixed plates 13 are fixedly installed at the position inside the recycling bin 1 on the right side of the conveying channel. A guide slide groove 15 used in conjunction with the slider 16 is provided at the inner end of the fixed plate 13. The edge material winding shaft 10 is driven to rotate by the driving motor inside the motor protection shell 18, thereby The edge material film 21 is rolled up. Since both ends of the fixed sleeve 17 and the movable sleeve 19 are slidably connected to the guide groove 15 through the slider 16, the fixed sleeve 17 and the movable sleeve 19 will not rotate with the edge material winding shaft 10. When the edge material winding shaft 10 needs to be replaced, it is only necessary to remove the motor protection shell 18 from the outer end of the recovery bin 1, and pull the edge material winding shaft 10 out from the inside of the recovery bin 1 through the through hole to replace the edge material winding shaft 10. It should be noted that after the edge material winding shaft 10 is installed into the two fixed plates 13 through the through hole, the motor protection shell 18 is fixed to the outer end of the recovery bin 1 by bolts. At this time, one end of the movable sleeve 19 is in contact with the inner wall of the recovery bin 1.

[0027] The method of using this embodiment is as follows: by installing an active rotating shaft 3 above the second driven conveying shaft 7, the active rotating shaft 3 drives multiple cutters 4 to rotate at high speed, and the PC film 20 passes through the second driven conveying shaft 7, the separation shaft 8, and the edge material winding shaft 10 in sequence. When the PC film 20 passes through the upper surface of the second driven conveying shaft 7, it will be cut into a specified size by the cutter 4 above the second driven conveying shaft 7 and continue to be conveyed. The main material film 22 that meets the specified size will enter the surface of the main material winding shaft 9 through the separation shaft 8 for winding, and the excess edge material film 21 will enter the surface of the edge material winding shaft 10 through the separation shaft 8, and will be transported to the inside of the crushing bin 5 by the edge material winding shaft 10, and will be crushed by two crushing rollers 11. The crushed edge material film 21 fragments will fall through the opening of the crushing bin 5.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein with equivalents.
