Description

Technical Field

[0001] The utility model belongs to the technical field of film material processing, and particularly relates to a film material conveying device. Background Art

[0002] Film materials such as PVC film materials have very wide applications in the industry, such as protective films on the screens of multimedia devices such as mobile phone screens and computer screens. Film materials have the characteristic of being soft in texture. Therefore, in the industry, in order to improve the performance of film materials, the finished film materials are mostly composite film structures, that is, multiple films with different performances are compounded into a film material with higher performance to meet the performance requirements.

[0003] In the process of film material production, the transmission of film materials is a key link in production, which is reflected in that the unwound film material needs to be transmitted over a long distance before it can reach the processing equipment for processing.

[0004] Due to the flexible characteristics of film materials, it is determined that during the transmission process, especially during long-distance transmission, the film material is slack, resulting in low transmission stability. Specifically, during the transmission process, due to the soft texture of the film material, it is easy to have different transmission rates or be too slack when the film material is unwound, resulting in low tension.

[0005] Low tension is likely to cause the film material to be too slack. In severe cases, the film material is easily contaminated due to the film material forming a loop. For example, when the slack film that fails to be effectively tensioned contacts the working equipment, the ground, etc., dust and other contaminating substances are adsorbed on the film material due to static electricity, resulting in the film material being contaminated.

[0006] The contaminated film material cannot be effectively cleaned at all, so it can only be treated as waste. However, in the actual production process, it is impossible to judge at all after the film material is contaminated due to slack and forming a loop. Only after entering subsequent processes such as coating and hot pressing can defects such as insufficient adhesive force and low tightness of hot pressing be found, which not only wastes a lot of manpower and material resources, but also causes serious material waste and economic losses.

[0007] Therefore, ensuring the stable transmission of thin film materials is very important for improving production efficiency and effect. Content of the Utility Model

[0043] Embodiment 1

[0044] As Figures 1-4 shown, a film material conveying device includes a film material conveying and tensioning mechanism; the film material is tensioned during the film material transmission process through the film material conveying and tensioning mechanism.

[0045] The membrane material conveying and tensioning mechanism includes a tensioning frame 1 arranged at intervals (connecting screws 11 are respectively installed at both ends of the tensioning frame 1 for installing the tensioning frame 1 on the transmission frame), and flipping tensioning components are respectively assembled and connected between both ends of the tensioning frame 1. Specifically, the flipping tensioning component includes flipping rods 21 that are respectively angle-adjustably installed on the tensioning frame 1, and a plurality of material guiding rollers 22 are rotatably connected between the flipping rods 21 (specifically, two parallel material guiding rollers 22 are rotatably connected to the flipping rod 21, and the membrane material is inserted between the material guiding rollers 22).

[0046] Specifically, rotating shafts are respectively fixedly connected to the flipping rods 21, and the rotating shafts are rotatably connected to the tensioning frame 1; a locking bolt 11 that locks onto the rotating shaft is threadedly connected to the tensioning frame 1.

[0047] During the working process, after the membrane material is inserted through the right flipping tensioning component, it is output after being inserted through the left flipping tensioning component. During the process of inserting the membrane material, in order to tension the membrane material, after loosening the locking bolt 11, the flipping rod 21 is flipped and rotated. At this time, the material guiding roller 22 raises or lowers the membrane material, and the membrane material is tensioned during the process of raising or lowering the membrane material. This method realizes tensioning the transmitted membrane material in a simple and effective manner, with simple tensioning operation and high tensioning effect.

[0048] Embodiment 2

[0049] As Figures 1-4 shown, on the basis of the structure of Embodiment 1, in order to further improve the tensioning effect on the membrane material, the above-mentioned membrane material conveying and tensioning mechanism further includes a plurality of elastic tensioning components arranged between the flipping tensioning mechanisms. Specifically, two elastic tensioning components arranged at intervals left and right are installed between the tensioning frames 1;

[0050] The right elastic tensioning component is installed between the tops of the tensioning frames 1, and the left elastic tensioning component is installed between the bottoms of the tensioning frames 1.

[0051] The specific structure of the elastic tensioning component is as follows:

[0052] The elastic tensioning component includes adjusting plates 31 respectively fixedly installed on the tensioning frame 1, a tensioning rod 32 is installed between the adjusting plates 31, and both ends of the tensioning rod 32 are slidably connected to the adjusting plates 31 through spring structures.

[0053] Specifically, chutes are opened on the adjusting plates 31; the spring structure includes slide rods 322 fixedly connected in the chutes, and L-shaped adjusting sliding seats 321 slidably connected to the slide rods 322 are respectively fixedly connected to both ends of the tensioning rod 32.

[0054] Meanwhile, the spring structure further includes a telescopic spring 323 sleeved on the sliding rod 322, and both ends of the telescopic spring 323 are fixedly connected to the L-shaped adjusting sliding seat 321 and the chute respectively.

[0055] During the working process, after the film material penetrates through the top of the tension rod 32 of the right elastic tensioning assembly, it penetrates through the bottom of the tension rod 32 of the left tensioning assembly.

[0056] Under the cooperation of tensioning and lower tensioning on the double-sided tension rod 32, the film material is fully tensioned. Specifically, by using the elastic force of the telescopic spring, the tension rod 32 elastically abuts against the film material, that is, while tensioning the film material, the film material is protected.

[0057] The above elastic tensioning assembly further includes a height adjustment structure, and the height adjustment structure includes long adjustment screws 33 respectively slidably connected to both sides of the adjustment plate 31; the bottom of the long adjustment screw 33 is fixedly connected to the tensioning frame 1; nuts 331 for adjusting the height of the tensioning frame 1 are respectively threadedly connected above and below the long adjustment screw 33.

[0058] During the working process, after loosening the nut 331, the height of the elastic tensioning assembly is adjusted, and then the tensioning force between the tension rod 32 and the film material is adjusted to achieve further adjustable tensioning.

[0059] Embodiment 3

[0060] As Figures 1-4 shown, on the basis of the structure of Embodiment 2, during the transmission of the film material, in order to correct the offset film material and transmit the film material along the normal trajectory, the above film material transmission device further includes a film transmission correction assembly respectively fixedly connected to the tensioning frame 1.

[0061] Specifically, the film transmission correction assembly includes a fixed seat, and an adjustment arm 42 is rotatably connected to the fixed seat. At the same time, the film transmission correction assembly further includes a motor 43 for driving the adjustment arm 42 to rotate. Specifically, the motor 43 is fixedly installed at the bottom of the fixed seat, and its output shaft is fixedly installed at the central position of the adjustment arm 42.

[0062] At the same time, push shafts 41 are respectively rotatably connected to both sides of the top of the adjustment arm 42. Specifically, the bottom of the push shaft 41 is fixedly connected to a short rotating shaft rotatably connected to the adjustment arm 42. During the working process, once the film material is offset, such as offset to the rear side, at this time, the operator turns on the motor 43 on the film transmission correction assembly at the rear side, drives the adjustment arm 42 to rotate close to the edge of the film material, and until the push shaft 41 abuts against the edge part of the film material. Along with the push shaft 41 continuously pushing the film material inward, the film material corrects its posture while being transmitted until the film material is transmitted along the normal trajectory.

[0063] Similarly, when the membrane material is displaced towards the front side, the transmission posture is corrected by the thin film transmission correction component on the front side.

[0064] Of course, the above description is not a limitation of the present utility model, and the present utility model is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the substantial scope of the present utility model should also fall within the protection scope of the present utility model.
