Description
Technical Field
[0001] The utility model relates to the technical field of film blowing machines, in particular to a PETG twisted film blowing machine. Background Art
[0002] The film blowing machine heats and melts plastic particles and then blows them into thin films. Dry polyethylene particles are added to the lower hopper of the extruder. The particles enter the screw from the hopper by their own weight. When the particles come into contact with the bevel of the thread, the rotating bevel surface produces a thrust perpendicular to the bevel surface on the plastic, pushing the plastic particles forward. During the pushing process, the plastic gradually melts due to the friction between the plastic and the screw, the plastic and the barrel, the collision and friction between the particles, and the external heating of the barrel. The molten plastic is filtered through the die head to remove impurities and comes out from the die head. It is cooled by the air ring, pulled, and rolled to form a finished film.

[0028] The key point of this scheme is the traction device, which does not require manual climbing and is easy to operate. Figure 1 and Figure 2 As shown, the traction device includes a support frame, a frame guide rail bracket 15 is installed on one side of one of the support frames, the top height of the frame guide rail bracket 15 is higher than the height of the support frame, a frame guide rail 14 is provided at one edge of the frame guide rail bracket 15, and a matching slider 9 is provided on the frame guide rail 14, and the slider 9 can make a circular motion along the frame guide rail 14, and a support arm 5 is horizontally connected to one side of the slider 9, so that the support arm 5 can move along the frame guide rail 14, and the support arm 5 is horizontally placed at the side of the support frame, as shown in FIG. Figure 1 As shown, a support 11 is vertically provided on one side of the slider 9 close to the support arm 5, and the support 11 is detachably connected to the support arm 5, and the two are specifically connected by bolts;
[0029] Support shafts 17 are provided at the four corners of the frame guide rail bracket 15. The support shafts 17 are respectively vertically installed on the side of the support frame body, and the free ends of the support shafts 17 are located outside the frame guide rail 14. A support groove wheel 13 is rotatably installed at the end of each support shaft 17. The four support groove wheels 13 are connected by a pull rope 7. The depth of the groove on the surface of the support groove wheel 13 is greater than the diameter of the pull rope 7, so that the pull rope 7 can be stuck inside the support groove wheel 13 and loosened;
[0030] like Figure 1 As shown, the pull rope 7 and the slider 9 are connected by an L-shaped connecting frame 10, and the height of the L-shaped connecting frame 10 can be climbed over the supporting frame body;
[0031] Specifically, the free end of the film extruded from the film blowing head 20 is fixed on the support arm 5. Specifically, a clamping rod 6 is provided on one side of the support arm 5, and bolts are vertically provided at both ends of the clamping rod 6. Two slots 23 corresponding to the bolts are provided on the support arm. The bolts are placed in the slots 23 and fastened by nuts. In this way, the free end of the film can be firmly clamped between the clamping rod 6 and the support arm 5. Then the operator pulls the pull rope 7 to allow the pull rope 7 to drive the support arm 5 to cross the top of the support frame and be placed on the outer side of the support frame. In this way, the extruded film can move from the traction device to the outside along with the support arm 5. Therefore, the operator only needs to pull the pull rope to complete the process of traction of the film, and there is no need to manually climb onto the traction frame.

The second arc rods 12 and the first arc rods 4 are both semicircular ring-shaped. The second arc rods 12 correspond to the first arc rods 4 one by one. The second arc rods 12 and the first arc rods 4 form a plurality of circular rings for supporting the extruded film.
[0035] The specific working process of the support frame is that before the extrusion work, the pull rope is pulled to stop the support arm 5 above the film blowing head 20, and then the film in the film blowing head 20 is locked and gradually extruded, and the free end of the film is fixed on the support arm 5. As the film is squeezed longer and longer, the operator can pull the pull rope to drive the support arm 5 to lift the film upward, and finally the film follows the support arm 5 to cross the top of the support frame 1, and the support arm drives the film to continue to move downward until it reaches a height that the operator can touch, and then the support arm 5 is placed at the bottom of the frame guide rail 14. In order to save the material of the frame guide rail 14, the frame guide rail 14 can be set to a U-shaped structure with the opening facing downward, but limit blocks are provided at both ends of the U-shaped structure to prevent the slider from falling.
