Description

Technical Field

[0001] This utility model relates to the field of insulating composite film technology, specifically to a blow molding device for insulating composite films. Background Technology

[0002] Blown film is one of the methods for forming plastic films. The process involves melting and plasticizing resin using an extruder to extrude it into a thin-walled tube. Then, under the action of a traction device, taking advantage of the polymer's good flowability at this point, compressed air is used to inflate it to the required thickness. After cooling and shaping, it becomes a film. If the film is not properly cut after production, it is prone to entanglement during the unwinding and winding process, requiring a new type of blown film equipment for insulating composite films.

[0003] The existing patent, CN212422165U, entitled "A Blow Molding Device for Plastic Composite Film," provides a blow molding device for plastic composite film, including a first cleaning ring, a first fixing block, a second fixing block, a second cleaning ring, a light, a handle, a battery compartment, fixing bolts, and cleaning brushes. The first cleaning ring is mounted on the annular side of the take-up roller, the first fixing block is mounted on the upper side of the first cleaning ring, the second cleaning ring is mounted on the right side of the first cleaning ring, the second fixing block is mounted on the upper side of the second cleaning ring, fixing bolts are installed inside the first fixing block and the second fixing block, a handle is mounted on the annular side of the first cleaning ring, a battery compartment is opened inside the first cleaning ring, a light is mounted on the front side of the first cleaning ring, a light is mounted on the front side of the second cleaning ring, and cleaning brushes are mounted on the inner walls of both the first and second cleaning rings. This utility model has a reasonable structure and facilitates the cleaning of the take-up roller in the plastic composite film blow molding device.

[0004] The above-mentioned device facilitates the cleaning of the take-up roller in the plastic composite film blow molding device. However, the composite film is not neat enough when it is wound onto the roller and is prone to entanglement, which causes unnecessary trouble in subsequent winding and unwinding processes and cannot meet people's needs. In view of the above situation, technical innovation is carried out on the basis of the existing blow molding device. Utility Model Content

[0005] The purpose of this invention is to provide a blow molding device for insulating composite films to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a blow molding device for insulating composite film, comprising a blow molding die and a conveyor belt, wherein an extruder is installed on the left side of the blow molding die and a hopper is installed above the extruder, the conveyor belt is installed on the right side of the blow molding die and a pressing assembly is installed on the left side of the conveyor belt, a bracket is installed below the pressing assembly and the bracket is embeddedly connected to the pressing assembly.

[0007] Furthermore, the pressing assembly includes a pressure roller and a damping rod, and damping rods are installed at both ends of the pressure roller. When the film bubble passes between the pressure rollers, the damping rods apply appropriate pressure to the pressure rollers, resulting in a better quality composite film after pressing.

[0008] Furthermore, a lead screw is installed on the left side of the damping rod, and side frames are installed at both ends of the lead screw.

[0009] Furthermore, a slider is installed around the lead screw, and the slider is threadedly connected to the lead screw. The threads of the left and right parts of the lead screw are in opposite directions, so that the sliders move synchronously towards each other, thereby driving the trimming knife on the slider to move.

[0010] Furthermore, a trimming knife is installed in the middle of the slider, and the trimming knife is embedded in the slider.

[0011] Furthermore, a sliding rod is installed at the lower end of the slider, and the sliding rod and the slider are slidably connected. The slider is restricted to move on the sliding rod and the lead screw, which facilitates the cutting of composite films that meet the specifications.

[0012] Furthermore, a roller is installed on the upper left side of the bracket, and the roller is rotatably connected to the bracket. The trimming knife cuts off the irregular parts of the edge, thereby rolling the neat composite film onto the roller for easy storage.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the raw material is poured into the hopper, the extruder blows out the film bubble through the blow molding die, the film bubble passes between two inclined conveyor belts and is gradually pressed together, and then the film bubble passes between the pressure rollers. The damping rod applies appropriate pressure to the pressure rollers. According to the specifications of the composite film being processed, the screw between the rotating side frame is rotated. The threads of the left and right parts of the screw are opposite, so that the slider moves synchronously towards each other, thereby driving the trimming knife on the slide rod to move. The trimming knife removes the irregular parts of the edge.

[0014] 1. In this invention, raw materials are poured into a hopper, and an extruder blows out film bubbles through a blow molding die. The film bubbles pass between two inclined conveyor belts, where they are gradually pressed together to prevent misalignment and wrinkles from occurring during the composite film pressing process. Subsequently, the film bubbles pass between pressure rollers, and a damping rod applies appropriate pressure to the pressure rollers, resulting in a better quality composite film.

[0015] 2. According to the specifications of the composite film being processed, the screw between the rotating side frames of this utility model has opposite thread directions on the left and right sides of the screw, causing the slider to move synchronously towards each other, thereby driving the trimming knife on the slide rod to move. The trimming knife cuts off the irregular parts of the edge, thereby rolling the neat composite film onto the roller for easy storage. Attached Figure Description
