Description

Technical Field

[0001] This utility model belongs to the field of PE film processing technology, and specifically relates to a PE film tension adjustment device. Background Technology

[0002] PE protective film is the simplest structural polymer organic compound and the most widely used polymer material in the world today. PE protective film uses special polyethylene (PE) plastic film as its base material and is classified into high-density polyethylene, medium-density polyethylene, and low-density polyethylene protective films according to their density. During the processing of PE protective film, a tension control system is needed to achieve automatic tension adjustment. However, current technology cannot adjust the position of the positioning mechanism according to the size of the PE film during tension processing, which easily leads to the risk of lateral displacement during film tension adjustment, causing wrinkles in the PE film and affecting product quality. Utility Model Content

[0003] In view of the above-mentioned shortcomings in the prior art, the present invention provides a PE film tension adjustment device to solve the problems in the background art.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A PE film tension adjustment device includes a base plate, with a second fixed plate symmetrically arranged on the upper end of the base plate. A first guide rod and a second guide rod are connected to the inner side of the second fixed plate. The first guide rod is slidably connected to a first limiting plate, and the second guide rod is slidably connected to a second limiting plate. The first limiting plate and the second limiting plate are jointly connected to a driving assembly for moving the first limiting plate and the second limiting plate. A first tension roller is arranged on the inner side of the second fixed plate. The first tension roller is connected to a rotating assembly for driving the first tension roller to rotate. A fifth fixed plate is connected to the upper end of the base plate. A winding drum is arranged on the upper end of the fifth fixed plate. A detection assembly is arranged on the outer side of the second fixed plate. An auxiliary tension adjustment assembly is arranged between the detection assembly and the fifth fixed plate.

[0006] Preferably, the detection component includes a tension sensor, a third fixing plate is symmetrically arranged on the outer side of the second fixing plate, a fixing column is connected to the inner side of the third fixing plate, and the tension sensor is sleeved on the outer side of the fixing column.

[0007] Preferably, a bidirectional threaded rod is rotatably connected to the inner side of the third fixing plate, a second motor is connected to the third fixing plate, the output shaft of the second motor is connected to the bidirectional threaded rod, and connecting blocks are connected to both ends of the bidirectional threaded rod, with the connecting blocks connected to a tension sensor.

[0008] Preferably, the drive assembly includes a first connecting plate, which is connected to a first limiting plate and a second limiting plate, and the first connecting plate is connected to a connecting block.

[0009] Preferably, the auxiliary tension adjustment assembly includes a fourth fixed plate, a bracket connected to the upper end of the fourth fixed plate, a third motor connected to the fourth fixed plate, a second tension roller rotatably connected to the inner side of the fourth fixed plate, the output shaft of the third motor connected to the second tension roller, a cylinder connected to the upper end of the bracket, a second connecting plate connected to the output end of the cylinder, a connecting column connected to the lower end of the second connecting plate, and a pressure roller connected to the lower end of the connecting column.

[0010] Preferably, the drive assembly includes a first motor, which is connected to a first fixed plate. A rotating shaft is rotatably connected to the inner side of the first fixed plate, and the rotating shaft is connected to a first tension roller.

[0011] Preferably, a control console is connected to the upper end of the base plate.

[0012] Preferably, the upper end of the base plate is connected to a first fixing plate, and the upper end of the first fixing plate is provided with a roll unwinding drum.

[0013] Compared with the prior art, this utility model has the following advantages:

[0014] 1. The first guide rod and the second guide rod are slidably connected to the first limiting plate and the second limiting plate respectively. When the second motor is started, it drives the bidirectional threaded rod to rotate, thereby causing the connecting blocks on both sides of the bidirectional threaded rod to move along the thread direction, thereby driving the first connecting plate connected to the connecting block to move. This allows the position of the first limiting plate and the second limiting plate connected to the first connecting plate to be adjusted. Since the first limiting plate and the second limiting plate are slidably connected to the first guide rod and the second guide rod, the PE film entering the first guide rod and the PE film output to the second guide rod can be limited, thereby accurately constraining the edge of the film. In addition, the tension sensor connected to the upper end of the connecting block simultaneously detects the tension of the PE film and makes rapid adjustments to avoid film deformation caused by uneven tension.

[0015] 2. By setting an auxiliary tension adjustment component, the second tension roller can be driven to rotate by a third motor, thereby adjusting the speed of film conveying. The cylinder drives the second connecting plate to move up and down. Since the second connecting plate is connected to a connecting column, and the connecting column is connected to a pressure roller, the height of the pressure roller is adjusted, changing the pressure of the pressure roller on the film, and further reducing the generation of wrinkles.

[0026] Furthermore, the detection assembly includes a tension sensor 17, a third fixing plate 7 symmetrically arranged on the outer side of the second fixing plate 4, a fixing post 29 connected to the inner side of the third fixing plate 7, the tension sensor 17 sleeved on the outer side of the fixing post 29, a bidirectional threaded rod 15 rotatably connected to the inner side of the third fixing plate 7, a second motor 6 connected to the third fixing plate 7, the output shaft of the second motor 6 connected to the bidirectional threaded rod 15, connecting blocks 16 connected to both ends of the bidirectional threaded rod 15, the connecting blocks 16 connected to the tension sensor 17, and the drive assembly includes a first connecting plate 18, the first connecting plate 18 connected to the first limiting plate 19 and the second limiting plate 20, and the first connecting plate 18 connected to the connecting block 16.

[0027] The auxiliary tension adjustment component of Yujing Peninsula includes a fourth fixed plate 8, a bracket 10 connected to the upper end of the fourth fixed plate 8, a third motor 9 connected to the fourth fixed plate 8, a second tension roller 26 rotatably connected to the inner side of the fourth fixed plate 8, the output shaft of the third motor 9 connected to the second tension roller 26, a cylinder 12 connected to the upper end of the bracket 10, a second connecting plate 23 connected to the output end of the cylinder 12, a connecting column 24 connected to the lower end of the second connecting plate 23, and a pressure roller 25 connected to the lower end of the connecting column 24. The drive component includes a first motor 5, which is connected to the first fixed plate 2. A rotating shaft 13 is rotatably connected to the inner side of the first fixed plate 2, and the rotating shaft 13 is connected to the first tension roller 14. A control console 11 is connected to the upper end of the base plate 1, and the first fixed plate 2 is connected to the upper end of the base plate 1. A roll unwinding drum 3 is provided on the upper end of the first fixed plate 2.

[0028] Working principle:

[0029] After the equipment is started, the PE film placed on the roll 3 on the upper end of the first fixed plate 2 first enters the conveying path. When it is necessary to adjust the width of the limiting plate to accommodate different PE films, the second motor 6 is started. When the second motor 6 is started, its output shaft drives the bidirectional threaded rod 15 on the inner side of the third fixed plate 7 to rotate. Since the connecting blocks 16 at both ends of the bidirectional threaded rod 15 are threadedly connected to the threaded rod, the connecting blocks 16 will move relative to each other along the thread direction. The movement of connecting block 16 causes the connected first connecting plate 18 to move synchronously, thereby adjusting the positions of the first limiting plate 19 and the second limiting plate 20 connected to the first connecting plate 18 on the first guide rod 21 and the second guide rod 22. The first limiting plate 19 can constrain the edge of the PE film entering the area of ​​the first guide rod 21, and the second limiting plate 20 can limit the edge of the PE film output to the area of ​​the second guide rod 22, thereby accurately constraining the edge of the film and preventing the film from shifting during the conveying process. The first motor 5 is connected to the first fixed plate 2, and its output shaft drives the rotating shaft 13 inside the first fixed plate 2 to rotate. The rotating shaft 13 is connected to the first tension roller 14, thereby realizing the rotation of the first tension roller 14 and driving the PE film to be continuously conveyed. Meanwhile, the tension sensor 17 connected to the upper end of the connecting block 16 is sleeved on the outside of the fixed post 29. During the process of limiting the film, the tension sensor 17 detects the tension of the PE film in real time. When uneven tension is detected, the relevant signal is transmitted to the control console 11. Then the control console 11 controls the cylinder 12, so that the output end of the cylinder 12 drives the second connecting plate 23 to move up and down. The connecting post 24 at the lower end of the second connecting plate 23 moves accordingly, and the height of the pressure roller 25 at the lower end of the connecting post 24 is also adjusted accordingly. The change in the height of the pressure roller 25 will change its pressure on the film. By adjusting the pressure, the film tension is further optimized, and the generation of wrinkles is reduced. After processing, the PE film is finally conveyed to the winding drum 28 at the upper end of the fifth fixed plate 27 to complete the winding operation.
