Description

Technical Field

[0001] This utility model relates to the field of stretch film processing equipment, and more particularly to a swing frame device in a film processing equipment. Background Technology

[0002] In existing technologies, the thickness of the stretch film is uneven when it exits the die head, with some areas being excessively thick. To solve this problem, a swing frame structure is usually used to make the film layer swing continuously during the winding process to achieve a uniform thickness distribution. However, the traditional swing frame structure has the following problems: the swing amplitude is not adjustable, it is fixed after installation, and cannot be flexibly adjusted according to the characteristics of the film layer; the operation stability is poor, the structural limit is imperfect, and there is a lack of effective limit and reinforcement structures. At high speeds (such as above 150 m / min), it is prone to violent shaking, affecting the uniformity of the film layer.

[0003] Therefore, there is an urgent need for a new type of swing frame device that is structurally stable, has an adjustable swing amplitude, and is suitable for high-speed operation. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by providing a swing frame device for thin film processing equipment.

[0005] The present invention solves the above-mentioned technical problems through the following technical solution:

[0006] A swing frame device in a thin film processing equipment includes a swing frame body and a fixed frame. Guide rollers and flattening rollers extending along the x-axis are respectively mounted on both sides of the swing frame body along the z-axis. A central beam extending along the z-axis is disposed in the center of the swing frame body. The swing frame body and another flattening roller are respectively mounted on both sides of the fixed frame along the y-axis. A crossbeam for mounting the swing frame body is disposed in the middle of the fixed frame along the z-axis. A pivot mounting seat is disposed in the center of the crossbeam. A swing center shaft extending along the y-axis is disposed within the pivot mounting seat. The swing center shaft is connected to the swing frame body via a bearing, allowing the swing frame body to swing around the swing center shaft in the plane formed by the x and y axes. The swing center shaft limits the swing frame body to a certain position on one side of the y-axis, enabling smooth fan-shaped swinging of the swing frame body around the swing center shaft.

[0007] The fixed frame is also equipped with a power mounting beam extending in the x-axis direction. The power mounting beam is equipped with a power mounting seat whose position is adjustable in the x-axis direction. A power source is installed on the power mounting seat. An eccentric block is installed at the output end of the power source. A linkage seat is installed on the middle beam. The eccentric block and the linkage seat are connected by a swing arm. The two ends of the swing arm are hinged to the eccentric block and the linkage seat, respectively. The power source drives the eccentric block to rotate, thereby driving the swing arm to swing the swing frame body.

[0008] Preferably, the swing frame body includes connecting plates at the four corners of a rectangle, and diagonal fixing rods are provided at the four corners of the fixed frame. The swing frame body and the fixed frame are connected by a limiting mechanism, which connects the connecting plates and the fixing rods to achieve connection in the z-axis direction. The limiting mechanism can buffer the floating of the swing frame body caused by its swing, keeping the distance between the swing frame body and the fixed frame at a fixed value, and maintaining stable winding during high-speed film winding.

[0009] Preferably, each limiting mechanism includes a limiting seat, which is fixedly connected to a fixed rod. The limiting seat has two fixing holes and a mounting shaft installed in the fixing holes. The mounting shaft is parallel to the connecting plate, and the end of the mounting shaft is provided with a guide wheel that can rotate around the mounting shaft. The front and rear guide wheels can rotate on the front and rear surfaces of the connecting plate, respectively. When the swing frame body swings, the front and rear guide wheels roll on the connecting plate, which can buffer the floating of the swing frame body caused by the swing of the swing frame body. The rolling motion dissipates part of the floating force of the swing frame body, thereby enhancing the load-bearing capacity and anti-vibration performance of the swing frame.

[0010] Preferably, the fixed rod is provided with a sliding groove extending in the y-axis direction, the limiting seat is accommodated in the sliding groove and can move back and forth along the sliding groove, and the limiting seat is locked to the fixed rod by bolts.

[0011] Preferably, the limiting seat has a part that mates with the slide groove and a part for setting the fixing hole.

[0012] Preferably, the two lower limiting seats are F-shaped, and there is a gap between the two parts of the limiting seats with fixing holes for the connecting plate to pass through, so that the guide wheel is located at the upper oblique end of the mounting shaft.

[0013] Preferably, the mounting shafts of the guide wheels installed on the two upper limit seats are perpendicular to the hypotenuse of the connecting plate, while the mounting shafts of the guide wheels installed on the two lower limit seats are parallel to the hypotenuse of the connecting plate. The lower part of the swing frame body is the side where the swing center axis is set, and the upper part needs to swing in a fan shape. The movement trajectory of the guide wheels on the connecting plate is relatively long. The perpendicularity of the mounting shaft to the hypotenuse of the connecting plate allows the guide wheels to swing in an arc along the extension direction of the hypotenuse.

[0014] As a preferred option, the power source is a right-angle geared motor. A right-angle geared motor can change the direction of rotation using helical gears or similar methods, allowing the motor output shaft to be mounted parallel to the power mounting beam, thus saving space.

[0015] Preferably, the position of the linkage seat on the center beam along the z-axis is adjustable. This allows for adjustment of the swing amplitude without replacing the swing arm.

[0016] This utility model, by adopting the above technical solution, has significant technical effects:

[0017] By adopting a swing center shaft and bearing connection method, the swing process is ensured to be smooth, reducing vibration and offset. Through stable swing motion, uniform distribution of film thickness is achieved, thereby improving product quality.

[0018] The power mounting base has an adjustment function, which can adaptively adjust the swing amplitude of the swing frame body according to different film specifications or film layer characteristics, thereby improving the applicability of the equipment and meeting different process requirements.

[0019] By using four-corner limiting devices, the limiting seat and the sliding groove locking structure of the fixed rod, together with the guide wheel, improve the stability of the device under high-speed operation, effectively avoid vibration, and are suitable for high-speed operating conditions.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0027] Example 1

[0028] A swing frame device in a thin film processing equipment, such as Figures 1-3As shown, the device includes a swing frame body 1 and a fixed frame 4. Guide rollers 2 and flattening rollers 3 extending along the x-axis are respectively installed on both sides of the swing frame body 1 in the z-axis direction. A central beam 11 extending along the z-axis direction is provided in the center of the swing frame body 1. The swing frame body 1 and another flattening roller 3 are respectively installed on both sides of the fixed frame 4 in the y-axis direction. A crossbeam 41 for mounting the swing frame body 1 is provided in the middle of the fixed frame 4 in the z-axis direction. A rotating shaft mounting seat 42 is provided in the center of the crossbeam 41. A swing center shaft 43 extending along the y-axis direction is provided in the rotating shaft mounting seat 42. The swing center shaft 43 is connected to the swing frame body 1 by a bearing so that the swing frame body 1 can swing around the swing center shaft 43 in the plane formed by the x and y axes.

[0029] The fixed frame 4 is also provided with a power mounting beam 44 extending in the x-axis direction. A power mounting seat 45 with an adjustable position in the x-axis direction is provided on the power mounting beam 44. A power source 46 is installed on the power mounting seat 45. An eccentric block 47 is installed at the output end of the power source 46. A linkage seat 12 is provided on the middle beam 11. The eccentric block 47 and the linkage seat 12 are connected by a swing arm 13. The two ends of the swing arm 13 are respectively hinged to the eccentric block 47 and the linkage seat 12. The power source 46 drives the eccentric block 47 to rotate, thereby driving the swing arm 13 to swing the swing frame body 1.

[0030] The swing frame body 1 includes a rectangular connecting plate 14 at the four corners, and a fixed rod 48 at the four corners of the fixed frame 4. The swing frame body 1 and the fixed frame 4 are connected by a limiting mechanism 49 to connect the connecting plate 14 and the fixed rod 48 to achieve the connection in the z-axis direction.

[0031] like Figure 4 As shown, each set of limiting mechanisms 49 includes a limiting seat 491, which is fixedly connected to the fixing rod 48. The limiting seat 491 is provided with two fixing holes 492 and a mounting shaft 493 installed in the fixing holes 492. The mounting shaft 493 is parallel to the connecting plate 14. The end of the mounting shaft 493 is provided with a guide wheel 494 that can rotate around the mounting shaft 493. The front and rear guide wheels 494 can rotate on the front and rear surfaces of the connecting plate 14 respectively.

[0032] The fixed rod 48 is provided with a slide groove 481 extending in the y-axis direction. The limiting seat 491 is accommodated in the slide groove 481 and can move back and forth along the slide groove 481. The limiting seat 491 is locked to the fixed rod 48 by bolts.

[0033] The limiting seat 491 has a part that mates with the slide groove 481 and a part for setting the fixing hole 492.

[0034] like Figure 5As shown, the two lower limiting seats 491 are F-shaped. The two parts of the limiting seats 491 are provided with fixing holes 492 and have a gap between them for the connecting plate 14 to pass through, so that the guide wheel 494 is located at the upper oblique end of the mounting shaft 493.

[0035] The mounting shafts 493 of the guide wheels 494 installed on the two upper limit seats 491 are perpendicular to the hypotenuse of the connecting plate 14, while the mounting shafts 493 of the guide wheels 494 installed on the two lower limit seats 491 are parallel to the hypotenuse of the connecting plate 14.

[0036] The power source 46 is a right-angle geared motor.

[0037] The swing frame device can be installed horizontally or vertically. In this embodiment, vertical installation is taken as an example. The film is wound in an S-shape around two flattening rollers 3 and guide rollers 2. During the film transport process, the swing frame body 1 can swing around the swing center axis 43 in the plane formed by the xy axis, thereby making the film evenly distributed.

[0038] The adjustment method of the swing frame body 1 is as follows: the fixed frame 4 is also provided with a power mounting beam 44 extending in the x-axis direction. The power mounting beam 44 is provided with a power mounting seat 45 whose position is adjustable in the x-axis direction. The power mounting seat 45 is locked by mechanical means such as bolts or locking blocks, or the power mounting seat 45 is connected to a power source that drives it to move along the x-direction. After each movement of the power source, the power mounting seat 45 is fixed in that position. As one embodiment, the position of the power mounting seat 45 changes, but the position of the linkage seat 12 does not change. By replacing the swing arm 13 with a swing arm of different lengths, or by making the swing arm itself telescopic, one side of the eccentric block 47 drives one end of the swing arm to make an arc-shaped movement to change the swing angle of the swing arm, thereby changing the swing amplitude. In one embodiment, the length of the swing arm 13 remains unchanged, the position of the power mounting seat 45 changes, and the position of the linkage seat 12 on the middle beam 11 along the z-axis direction can be adjusted, thereby changing the angle between the swing arm at its initial position and the x-axis direction. When the eccentric wheel rotates, the swing arm swings and acts on the linkage seat 12. Since the position of the swing center axis 43 of the swing frame body 1 remains unchanged, the movement amplitude of the swing arm changes, and the stroke also changes, thereby changing the swing amplitude of the swing frame body 1 accordingly.
