Description

Technical Field

[0001] This utility model relates to the field of thin film production technology, specifically to a fully automatic blown film unwinding and core-changing equipment. Background Technology

[0002] After the film is produced, it needs to be wound around a paper core tube by a winding machine to form a roll. During the winding process, the paper core tube is wrapped around the winding shaft, which drives the paper core tube to rotate continuously, thereby continuously winding up the film material. When the set length and the film roll reach the set diameter, the film roll along with the paper core tube needs to be unloaded (this process is called "unwinding"), and the film roll (along with the paper core tube) is pulled out from the winding shaft and then a new paper core tube is installed on the winding shaft. This process is called "core changing". The traditional core changing process mainly relies on manual labor, has a low degree of automation, high labor intensity for workers, and is time-consuming.

[0025] like Figure 1 As shown, in this embodiment, four columns 19 are fixedly connected to the mounting base 18, and a fixing frame 5 is fixedly connected to the columns 19. The fixing frame 5 and the columns 19 form a square frame. A first lead screw slide 2 is fixedly connected to the fixing frame 5. A second cylinder 8 is fixedly connected to the slide of the first lead screw slide 2. A mounting frame 9 is fixedly connected to the piston rod of the second cylinder 8. A first pneumatic gripper 10 is fixedly connected to each end of the mounting frame 9. A first servo motor 1 is fixedly connected to the fixing frame 5. A through hole is opened on the fixing frame 5. The rotating shaft of the first servo motor 1 passes through the through hole of the fixing frame 5 and is fixedly connected to the lead screw of the first lead screw slide 2. The rotating shaft of the first servo motor 1 does not contact the through hole of the fixing frame 5. Starting the first servo motor 1 can control the left and right displacement of the slide of the first lead screw slide 2.

[0026] A second lead screw slide 4 is fixedly connected to the fixed frame 5. A slide plate 6 is fixedly connected to the slide plate 4. Two first cylinders 7 are fixedly connected to the slide plate 6. The piston rod of the first cylinder 7 is fixedly connected to the second pneumatic gripper 17.

Starting the second servo motor 3 can control the left and right displacement of the slide plate of the second lead screw slide 4.

[0027] The mounting base 18 is fixedly connected to the film winding table 16, and the first core 23 and the second core 24 are placed on the film winding table 16. The core rod 21 is slidably connected inside the first core 23 and the second core 24.

[0029] In this embodiment, both the cylinder and the servo motor are connected to a power source and are connected to the controller via signal lines.

[0030] The working principle of this utility model is as follows: A first core 23 is placed on each side of the second core 24 after film winding is completed on the film winding table 16. The three cores are threaded together by the core rod 21. The second servo motor 3 is started, causing the first cylinder 7 to move to the core tube. The first cylinder 7 extends its piston rod, simultaneously activating the second pneumatic gripper 17 to clamp the first cores 23 on both sides. Then, it is raised and moved to the left to the core gripper 22, lowered, and placed inside the core gripper 22. The second pneumatic gripper 17 then disengages from the core. At the same time, the core rod clamp 20 clamps the core rod 20, the third cylinder 15 is started so that the support plate 25 supports the second core 24, the third servo motor 27 is started so that the pull-out frame 13 drives the core rod 21 to be pulled out. After the core rod 21 is pulled out, the two first cores 23 on both sides are clamped by the core clamps 22 on both sides respectively, and the second core 24 in the middle is supported by the support plate 25. Then the third cylinder 27 retracts, and the support plate 25 drags the second core 24 down. At this time, the second core 24 contacts the unloading plate 12 and rolls down along the unloading plate 12 to complete the unloading.

[0031] The second core tube 24 that has not been rolled into film is placed on the feeding plate 11. The first servo motor 1 and the second cylinder 8 are started to make the first pneumatic gripper 10 clamp the second core tube 24 tightly and send it to the top of the support plate 25. The third cylinder 15 is started to raise the support plate 25 and place the second core tube 24 on the support plate 25, making the second core tube 24 coaxial with the first core tube 23. The third servo motor 27 is started to drive the pull-out frame 13 and the core bar 21 to insert into the core tube. After completion, the core bar gripper 20 and the core tube gripper 22 are released. The second servo motor 3 and the first cylinder 7 are started again to make the second pneumatic gripper 17 clamp the second core tube 24 and place it on the film winding table 16 to complete the film winding. This cycle can be repeated.
