DETAILED DESCRIPTION
[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0024] Reference Figure 1-5 A PE blown film automatic production line comprises a frame 1 and a PE film body 2. Two squeezing rollers 3 are installed on the upper end of the frame 1.
[0025] The winding mechanism is used to wind up the PE film body 2. The winding mechanism includes two L-shaped plates 4 fixedly connected to the upper end of the frame 1. The winding mechanism also includes a winding roller 6. The side wall of the L-shaped plate 4 is provided with an L-shaped through groove 5. The side walls of the winding roller 6 are respectively fixedly connected to two rotating shafts 7, and the rotating shaft 7 is located in the L-shaped through groove 5.
[0026] Further, such as Figure 1 As shown, the PE film body 2 passes through two squeezing rollers 3 and is then rolled up on a winding roller 6 . At this time, the two squeezing rollers 3 can flatten the PE film body 2 .
[0027] The clamping mechanism is used to clamp the PE film body 2. The clamping mechanism includes a connecting plate 8 fixedly connected between two L-shaped plates 4. The lower end of the connecting plate 8 is fixedly connected to a fixing frame 9. The inner wall of the fixing frame 9 is slidably connected to a clamping plate 10. The side wall of the clamping plate 10 is in contact with the PE film body 2. The inner wall of the fixing frame 9 is elastically connected to the side wall of the clamping plate 10 through a plurality of springs 11.
[0028] Furthermore, when the winding roller 6 winds up the PE film body 2, the clamping plate 10 is tightly fitted with the PE film body 2 under the action of multiple springs 11, and then the PE film body 2 on the winding roller 6 is pressed, avoiding the phenomenon in the prior art that when the motor stops, the wound PE film is easily loosened, resulting in the PE film being loosely wound when it is continued to be wound.
[0029] The dust suction mechanism includes a dust collector 14 fixedly connected to the lower end of the frame 1, a dust suction pipe 12 is fixedly connected to the side wall of the pressing plate 10, a dust suction port 13 is opened at the bottom of the dust suction pipe 12, the input end of the dust collector 14 is connected to the inner wall of the dust suction pipe 12 through the dust suction pipe 15, and the output end of the dust collector 14 is connected to an external dust collecting bag.
[0030] Furthermore, when the pressing plate 10 presses the PE film body 2, the pressing plate 10 will scrape off the fluff on the PE film body 2. At this time, the vacuum cleaner 14 is started to extract the fluff to prevent the fluff from floating in the workshop.
[0031] The frame 1 is provided with a rotating mechanism for driving the winding roller 6 to rotate, and the rotating mechanism includes a first wheel 17, and the first wheel 17 is connected to one of the rotating shafts 7 through a connecting mechanism. A motor 20 is fixedly connected to the upper end of the frame 1, and a second wheel 21 is fixedly connected to the movable end of the motor 20. A synchronous belt is connected between the first wheel 17 and the second wheel 21.
[0032] The connection mechanism includes a collar 16 fixedly connected to the side wall of the first wheel 17, wherein two threaded holes 18 are provided on the side wall of one of the rotating shafts 7, and two bolts 19 are threadedly connected to the side wall of the collar 16, and the two bolts 19 are threadedly connected to the inner walls of the two threaded holes 18 respectively.
[0033] Furthermore, the motor 20 is connected to one of the rotating shafts 7 through a connecting mechanism, and the rotation of the motor 20 drives the rotating shaft 7 to rotate through the first wheel 17, the synchronous belt and the second wheel 21, and then drives the winding roller 6 to rotate. When the winding roller 6 needs to be removed, the synchronous belt is first removed from the first wheel 17, and then the two bolts 19 are rotated to separate from the threaded holes 18, so as to complete the separation between the first wheel 17 and the rotating shaft 7;
[0034] After the subsequent replacement, it is only necessary to install the first wheel 17 on the rotating shaft 7 again, and then connect the synchronous belt between the first wheel 17 and the second wheel 21.
[0035] When the PE film body 2 is rolled up, the PE film body 2 is passed between the two squeezing rollers 3, and the side walls of the two squeezing rollers 3 are in contact with the side walls of the PE film body 2, and then the PE film body 2 is in contact with the side wall of the winding roller 6. At this time, the pressing plate 10 is in close contact with the PE film body 2 under the elastic force of the multiple springs 11;
[0036] Then the driving motor 20 rotates, and then the first wheel 17, the synchronous belt, the second wheel 21 and the ring 16 drive the rotating shaft 7 to rotate, and then the winding roller 6 rotates to wind up the PE film body 2. During this process, the pressing plate 10 maintains a close fit with the PE film body 2, and then presses the PE film body 2 on the winding roller 6, so as to avoid the phenomenon in the prior art that when the motor stops, the rolled PE film is easily loosened, resulting in the PE film not being rolled tightly when it is subsequently rolled up;
[0037] At this time, the vacuum cleaner 14 is started, and the fluff scraped off by the pressing plate 10 can be discharged into an external dust collection bag through the dust suction pipe 15, the dust suction pipe 12 and the plurality of dust suction ports 13.
[0038] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
