AI Technical Summary
During the production of PO film, it is difficult to keep the winding speed of the take-up rollers consistent, resulting in a speed difference in the film material. This can easily cause the film material to be too loose or too tense, damaging the film material and affecting the winding effect.
A tension control structure for PO film production was designed, including a winding assembly and a tension adjustment assembly. By cooperating with limit bolts, sliding blocks and sliding grooves, the positions of the first tension roller and the second tension roller are adjusted to ensure that the film tension is appropriate and to avoid being too loose or too tight.
Effectively regulating the film tension ensures smooth winding of the take-up roller, improving the winding effect of PO film and preventing film damage.

It is usually a polymer of ethylene, propylene or high-grade olefin. Among them, ethylene (PE) and propylene (PP) are the most important. PO film is a new type of agricultural film produced by Japan using high-grade olefin raw materials and other additives through an external spraying and drying process. Its advantages are more prominent, and it has more advantages than traditional PE film and EVA film on the market, but the price is relatively high.

[0025] Please refer to Figures 1-4 , the present application provides a PO film production tension control structure, comprising a winding assembly 10 and a tension adjusting assembly 20.
[0026] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4The winding assembly 10 comprises a frame body 110, the inside of the frame body 110 is sequentially rotatably provided with a first tension roller 140 and a winding roller 120 from front to back, and the frame body 110 is rotatably provided with a second tension roller 170 above the first tension roller 140; wherein the po film to be wound is placed between the first tension roller 140 and the second tension roller 170 and then wound on the winding roller 120, so that the po film can be wound. Through the setting of the first tension roller 140 and the second tension roller 170, the po film to be wound can be pressed and limited, so that the winding roller 120 can be wound more smoothly.
[0027] In the embodiment, one side of the frame body 110 is provided with a moving piece 130, and the moving piece 130 is screwed through the side wall of the frame body 110 and can be extended into and withdrawn from the inside of the winding roller 120.

The moving piece 130 comprises a hand wheel 131 and a threaded rod 132, one end of the threaded rod 132 is fixedly connected with the hand wheel 131, the other end of the threaded rod 132 is sequentially screwed through the mounting frame 160 and the side wall of the frame body 110 and is rotatably connected with a supporting roller 133, one end of the supporting roller 133 close to the winding roller 120 is rotatably connected with a connecting roller, and the connecting roller can be extended into and withdrawn from the inside of the winding roller 120.
[0028] Please refer to Figure 1 , Figure 3 and Figure 4The tension adjusting assembly 20 comprises two sliding plates 210, the opposite surfaces of the two sliding plates 210 are sequentially fixedly connected with a fixed piece 220 and an L-shaped plate 230 from top to bottom, the two ends of the first tension roller 140 are rotationally connected with the two L-shaped plates 230 respectively, the two ends of the second tension roller 170 are rotationally connected with the two fixed pieces 220 respectively, and the two sliding plates 210 are slidably connected with the opposite side walls of the frame body 110 respectively. The outer sides of the two sliding plates 210 are fixedly connected with sliding blocks 260, and the two side walls of the frame body 110 are provided with sliding grooves 111 matched with the sliding blocks 260. The outer sides of the two sliding blocks 260 are fixedly connected with connecting plates 240, the connecting plates 240 are provided with limiting bolts 250 in threaded connection, the shanks of the limiting bolts 250 are in close contact with the outer side walls of the frame body 110, and the outer side wall of the frame body 110 is provided with a first strip-shaped sliding groove 112 matched with the shank of the limiting bolt 250. When the po film is too loose or the tension is too large during winding, the limiting bolts 250 on the two outer sides of the frame body 110 are loosened to be not in contact with the side walls of the frame body 110, then the connecting plate 240 is slid, the sliding block 260 slides left and right in the sliding groove 111, the fixed piece 220 drives the first tension roller 140 and the second tension roller 170 to slide left and right on the frame body 110, so that the first tension roller 140 and the second tension roller 170 are adjusted, and after sliding to the appropriate position, the limiting bolt 250 is tightened and fixed. Through the cooperation of the limiting bolt 250 and the sliding block 260, when the po film between the first tension roller 140 and the second tension roller 170 and the winding roller 120 is too loose or the tension is too large, the tension can be adjusted, so that the winding effect of the winding roller 120 on the po film is better.
[0029] In the specific setting, the fixed piece 220 comprises a first fixed block 221 fixedly connected with the sliding plate 210, the sliding plate 210 is fixedly connected with a fixed plate 223 below the first fixed block 221, a guide rod 224 is fixedly connected between the fixed plate 223 and the first fixed block 221, a moving block 222 is slidably sleeved on the outer side of the guide rod 224 between the fixed plate 223 and the first fixed block 221, and the two ends of the second tension roller 170 are rotationally connected with the two moving blocks 222 respectively. When the po film needs to be placed between the first tension roller 140 and the second tension roller 170, the second tension roller 170 is lifted upward, at this time, the two moving blocks 222 move upward along the guide rod 224, and then the second tension roller 170 also moves upward, so that a gap is formed between the first tension roller 140 and the second tension roller 170. After the po film is placed, the second tension roller 170 is loosened, and under the action of gravity, the second tension roller 170 automatically descends to press the po film, and then rotation is realized to convey the po.
[0030] The working principle of the PO film production tension control structure is as follows:
[0031] When the po film is too loose or too much tension when winding, first loosen the limiting bolt 250 on both sides of the frame body 110, which is not in contact with the side wall of the frame body 110, then slide the connecting plate 240, so that the sliding block 260 slides left and right inside the sliding groove 111, and then the first tensioning roller 140 and the second tensioning roller 170 driven by the fixing piece 220 can slide left and right on the frame body 110, thereby adjusting the first tensioning roller 140 and the second tensioning roller 170, and then tighten the limiting bolt 250 to fix it after sliding to the appropriate position. Through the cooperation of the limiting bolt 250 and the sliding block 260, when the po film between the first tensioning roller 140 and the second tensioning roller 170 and the winding roller 120 is too loose or the tension is too large, the tension can be adjusted, thereby ensuring that the winding effect of the winding roller 120 is better when winding the po film. Through the setting of the first tensioning roller 140 and the second tensioning roller 170, the po film to be wound can be pressed and limited, so that the winding roller 120 is more smooth when winding.
