Description

Technical Field

[0001] The utility model belongs to the technical field of film production, and particularly relates to a device for adjusting the thickness of a stretched film. Background Art

[0002] Film stretching production is a technology that improves the physical properties of polymer films through the stretching process, and is widely used in the production of electronic components, ceramic substrates, multi-layer ceramic devices, etc. The preparation of polymer films by the stretching method includes process steps such as mixing, evaporation, drying, and cutting, and can produce film products with excellent properties. During the production process of the film, before the film is stretched, it is necessary to process the film to increase the uniformity of the stretched film. However, it still has the following disadvantages in actual use:

[0003] During the processing of the film, it is directly heated and softened by roll pressing to facilitate its subsequent stretching deformation. However, during the processing of the film, stretching is also required. When it is conveyed to the stretching processing equipment after roll pressing, when the stretching processing equipment vibrates, it is easy to cause different stretching lengths of the film at the output position of roll pressing heating, affecting the uniformity of film stretching;

[0004] During the processing of the film, it is directly conveyed to a heating device and heated in the heating device, so that after being subjected to a tensile force, it stretches and deforms to increase the length of the film. When running, during the heating process of the film, it is easy to cause the width of the film to increase due to roll pressing, and after stretching, it is stretched too thin, affecting the production quality of the film. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a device for adjusting the thickness of a stretched film. By setting a frame, a support arm, a base, and a guide roller, the problem that when the film is directly roll-pressed and heated during processing, the temperature change of the film is used to control the deformation degree of the film under stretching, and when adjusting the thickness during the stretching process and discharging the film after roll-pressing heating, it is easy to cause uneven stretching thickness due to machine vibration, and the width will increase during roll-pressing heating, affecting the thickness accuracy of the stretched film, is solved.

[0006] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0007] The utility model relates to a device for adjusting the thickness of a stretched thin film, which comprises a frame, support arms, a base and guide rollers. At both short sides of the top of the base, support arms are fixed. The tops of the two support arms are jointly fixed with the frame. Along the horizontal center line at the bottom of the frame, a first moving track is fixed. The outside of the first moving track is movably connected with a first electric hoist. The bottom of the first electric hoist is fixed with a hot air blower. On one side of the two support arms, guide rollers are jointly arranged. During operation, the first moving track is fixed at the bottom thereof through the frame, the frame is supported at the top thereof through the support arms, the support arms and the frame are supported on a workbench surface through the base, and the plastic thin film is guided between the hot air blower and the support base through the guide rollers.

[0008] Further, at the lower parts of the sides of the support arms close to the guide rollers, mounting plates are fixed. The mounting plates are arranged at two mutually separated vertical edges on the sides of the two support arms close to the guide rollers. A mounting opening is vertically and penetratingly formed on one side of the mounting plate. The support arms support the guide rollers thereon through the mounting plates.

[0009] Further, along the horizontal center line at the top of the base, a second moving track is fixed. The two ends of the second moving track are respectively fixed on the mutually close surfaces of the two support arms. The base movably connects a second electric hoist thereon through the second moving track.

[0010] Further, the two ends of the first moving track are respectively fixed on the mutually close surfaces of the two support arms. The second moving track and the first moving track are in corresponding positions. The first moving track and the second moving track are in corresponding positions, which increases the convenience of the synchronous operation of the first electric hoist and the second electric hoist.

[0011] Further, the outside of the second moving track is movably connected with a second electric hoist. The top of the second electric hoist is fixed with a support base. The second electric hoist and the first electric hoist are in corresponding positions. The second moving track drives the support base to move together with the hot air blower through the second electric hoist.

[0012] Further, at both ends of the guide roller, turntables are rotatably connected. At the ends of the turntables away from the guide roller, mounting rods are fixed. At the ends of the mounting rods away from the turntables, limit blocks are fixed. The two mounting rods respectively penetrate and are movably connected in the mounting openings on the two mounting plates. The guide roller is movably connected in the mounting openings on the mounting plates through the mounting rods connected with the turntables, so that the guide roller is supported on the support arms.

[0013] The utility model has the following beneficial effects:

[0014] The utility model solves the problem that during the processing of the film, when directly roller-pressing and heating, due to the temperature change of the film, it is difficult to control the degree of deformation of the film caused by stretching, and it is easy to cause uneven stretching thickness when discharging the film after roller-pressing and heating during the stretching process, by setting a frame, a support arm and a base. When starting the electric hoist one and the electric hoist two, the hot air blower is driven by the electric hoist one to move between the frame and the base along the length direction of the moving track one, and the support seat and the hot air blower are driven by the electric hoist two to move synchronously. After the hot air blower heats the air, it blows the air onto the film passing over the top of the support seat, so that the film is heated. When the film is heated, its temperature rises, increasing the uniformity of the force on each position of the film during stretching and enhancing the uniformity of the film during the stretching process.

[0015] The utility model solves the problem that when directly roller-pressing and heating the film during the processing, it will cause the width of the film to increase, affecting the thickness accuracy of the stretched film, by setting a frame, a support arm, a base and a guiding roller. After the plastic film is conveyed to the outside of the frame by an external conveying structure, it passes through the circumference of the guiding roller through a plurality of pipes and is conveyed between the hot air blower and the support seat. At the same time, the electric hoist one and the electric hoist two are started, so that the hot air generated by the hot air blower blows onto the film, and the film is supported by the support seat to prevent the hot air blown out by the hot air blower from deforming the plastic film. During the operation, the film is directly blown soft by the hot air, and the film is also supported by the support seat, so that its width will not change during the heating process, and the thickness accuracy of the stretched film is higher.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention. First specific embodiment

[0025] Please refer to Figures 1-4 , the present invention is a device for adjusting the thickness of a stretched thin film, including a frame 1, a support arm 2, a base 3 and a guide roller 4. Support arms 2 are fixed at both short sides of the top of the base 3. When the base 3 is working, the support arms 2 are supported on the working platform, and the frame 1 is connected and supported on the base 3 through the support arms 2. The tops of the two support arms 2 are jointly fixed with the frame 1, and the first moving track 101 is fixedly supported at the bottom of the frame 1 through the frame 1. The first moving track 101 is fixedly supported along the horizontal center line at the bottom of the frame 1. The outside of the first moving track 101 is movably connected with the first electric hoist 102, and the bottom of the first electric hoist 102 is fixed with a hot air blower 103. The first electric hoist 102 is movably connected to the first moving track 101 through the first moving track 101 to provide support during the operation of the first electric hoist 102. The hot air blower 103 is fixed on the first electric hoist 102. When the hot air blower 103 is working, hot air is blown between the hot air blower 103 and the support seat 303, so that the plastic film passing through the top of the support seat 303 is heated, which is more convenient for stretching to a suitable thickness during stretching. A guide roller 4 is jointly arranged on one side of the two support arms 2, and the plastic film is guided to between the hot air blower 103 and the support seat 303 through the guide roller 4.

[0026] Specifically, mounting plates 201 are fixed at the lower parts of the support arms 2 close to the guide roller 4. The mounting plates 201 are arranged at two mutually separated vertical edges on the side of the two support arms 2 close to the guide roller 4. A mounting opening 202 is vertically penetrated on one side of the mounting plate 201. The support arm 2 movably connects the mounting rod 402 through the mounting opening 202 on the mounting plate 201, so that the guide roller 4 is supported on the support arm 2.

[0027] Further, a second moving track 301 is fixed along the horizontal center line at the top of the base 3. The two ends of the second moving track 301 are respectively fixed on the mutually adjacent surfaces of the two support arms 2. The base 3 supports the second electric hoist 302 on the base 3 through the second moving track 301.

[0028] Further, the two ends of the first moving track 101 are respectively fixed on the mutually adjacent surfaces of the two support arms 2. The second moving track 301 and the first moving track 101 are in corresponding positions. By corresponding to each other, the first moving track 101 and the second moving track 301 facilitate the position correspondence between the first electric hoist 102 and the second electric hoist 302.
