The end of the double-layer bag-packaged film which is subjected to blow molding flattening extends between the cutting knife 84 and the knife holder 81, the elastic telescopic rod 83 is pressed downwards to drive the cutting knife 84 to be inserted into the knife groove 82, and meanwhile, the end of the film is cut, so that the end of the film forms a strip-shaped opening, and the double-layer film is sleeved on the horizontal plate 2 conveniently.
The troweling mechanism 9 includes a mounting plate 91, a first guide groove 92, a second guide groove 93, a first link 94, a second link 95, a connecting rod 96, a second motor 97, a second bidirectional screw 98, and a press roller 99. The mounting plate 91 is parallel to the horizontal plate 2 and is fixedly connected to the vertical rod 10. The mounting plate 91 is provided with a first guide groove 92 and a second guide groove 93 which are parallel to each other in the left-right direction. Two telescopic first connecting frames 94 are symmetrically and slidably matched in the first guide groove 92 in a left-right mode, and two telescopic second connecting frames 95 are symmetrically and slidably matched in the second guide groove 93 in a left-right mode. A connecting rod 96 perpendicular to the first guide groove 92 is horizontally and fixedly installed between the corresponding first and second connecting frames 94 and 95. A second motor 97 is fixedly mounted on the mounting plate 91 through a motor base, and a second bidirectional screw 98 parallel to the first guide groove 92 is fixedly mounted at the output end of the second motor 97. A second bidirectional lead screw 98 extends through the connecting rod 96 and is threadedly and rotatably engaged with the connecting rod 96. A pressing roller 99 perpendicular to the first guide groove 92 is horizontally rotatably installed between the corresponding first and second link frames 94 and 95. In the process of rolling the film by the rolling mechanism 7, the pressing roller 99 is separated from the surface of the film, and the second motor 97 drives the second bidirectional screw 98 to rotate in the forward direction, so as to drive the two connecting rods 96 to move from the left side to the right side to the middle, and further drive the two pressing rollers 99 to move from the left side to the right side to the middle. In the process that the film is wound by the winding mechanism 7 in a pause mode, the film is in a static state, the compression rollers 99 are attached to the surface of the film, and the second bidirectional screw 98 is driven to rotate reversely by the second motor 97, so that the two connecting rods 96 are driven to move from the middle to the left and right sides, and the two compression rollers 99 are driven to move from the middle to the left and right sides to trowel the film.
In this embodiment, the first connecting bracket 94 includes a guide sleeve 941, a sliding rod 942, a first magnet 943, a second mushroom nail 944, a second card slot 945, and a spring 946. The guide sleeve 941 is horizontally slidably mounted in the first guide groove 92 in the left-right direction, and the slide rod 942 is vertically slidably mounted in the guide sleeve 941. The slide bar 942 is rotatably provided with a press roller 99. Fixed mounting has first magnet piece 943 on the slide bar 942 terminal surface, and fixed mounting has second mushroom nail 944 on the first magnet piece 943, offers on the inside terminal surface of uide bushing 941 with the second draw-in groove 945 of mutually supporting of second mushroom nail 944. A spring 946 is vertically arranged between the inner end surface of the guide sleeve 941 and the first magnet block 943; the first and second connecting frames 94 and 95 are identical in structure. The floating mechanism 9 further includes a strip plate 910, a second magnet block 911, and a third magnet block 912. A strip-shaped plate 910 is horizontally and fixedly mounted on the mounting plate 91 at a position corresponding to the first guide groove 92 and the second guide groove 93. Two second magnet blocks 911 are symmetrically and fixedly mounted in the left and right of the middle of the strip-shaped plate 910, and two third magnet blocks 912 are symmetrically and fixedly mounted at the left and right ends of the strip-shaped plate 910. When the first connecting frame 94 is located at two sides of the first guide slot 92, a suction force is generated between the third magnet piece 912 and the first magnet piece 943, so that the first magnet piece 943, the sliding rod 942, the second mushroom nail 944 and the press roller 99 are driven to move in the vertical direction against the elastic force of the spring 946 until the second mushroom nail 944 is clamped into the second clamping slot 945; the press roller 99 is separated from the surface of the film. When the first connecting frame 94 drives the press rollers 99 to move towards the middle from the left side and the right side, the second mushroom nails 944 are always clamped in the second clamping grooves 945, so that the press rollers 99 are always separated from the surface of the film, and the left and right transverse movement of the press rollers 99 cannot cause the surface of the film to generate wrinkles when the film moves in the front-back direction and is rolled. When the first connecting frame 94 moves to the middle of the first guide groove 92, the magnetic force repelling each other is generated between the second magnet piece 911 and the first magnet piece 943, and under the combined action of the magnetic force and the elastic force of the spring 946, the first magnet piece 943 drives the second mushroom nail 944 to be separated from the second clamping groove 945, and drives the sliding rod 942 and the press roller 99 to slide along the vertical direction until the press roller 99 is attached to the surface of the film. Subsequently, the winding mechanism 7 suspends winding the film, the film enters a static state, and the pressing rollers 99 are driven by the first connecting frame 94 and the second connecting frame 95 to move from the middle to the left and right sides, so that the surface of the film is smoothed.
As shown in fig. 1, the embodiment further provides a process for preparing a biodegradable high-barrier plastic film material, which is completed by matching the biodegradable high-barrier plastic film material preparation machine, and the process includes the following steps:
step one, cutting the end part of the film: the flattened end part of the double-layer bagged film formed by blow molding extends into a cutting mechanism 8, and the end part of the film is cut by the cutting mechanism 8 to form an opening.
Step two, opening the double-layer film: a film with an opening formed at the end part is sleeved on the horizontal plate 2, the screw rod 15 is rotated to drive the door-shaped frame 14 to horizontally move to extrude hydraulic oil in the oil groove 12, and the sealing rod 13 is further used for pushing the sliding plate 4 and the supporting bar 5 to horizontally slide towards the left side and the right side synchronously, so that the internal tensioning of the film is realized.
Step three, cutting and simultaneously winding: the film is divided into an upper film and a lower film by the dividing mechanism 6, the upper film and the lower film are simultaneously and periodically rolled by the rolling mechanism 7, and the press rollers 99 in the trowelling mechanism 9 are always separated from the surface of the film and move from the left side to the right side to the middle in the rolling process. In the process of suspension of winding, the press rollers 99 in the troweling mechanism 9 are attached to the surface of the film and move from the middle to the left and right sides, so that the film before winding is trowelled.
