DETAILED DESCRIPTION

[0048] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0049] Example 1:

[0050] In this embodiment, as Figures 1-3 As shown, the present invention proposes a PE film anti-wrinkle winding device, including a base plate 1 with an installation space at the top, and further including a guiding component 2, a cooling component 3, a conveying component 4, an adjusting component 5, and a winding component 6. The bottom of the guiding component is connected to the base plate, and the guiding component can guide and flatten the film 7 produced by the blown film machine; the cooling component is located behind the guiding component and can regulate the temperature of the film; the conveying component is located behind the cooling component and can convey and further flatten the film; the adjusting component is located behind the conveying component and can adjust the tension of the film; the winding component is located behind the adjusting component and can receive and wind the film.

[0051] In this example, after the blown film extrudes the film bubble, the film bubble is clamped to form a film, and then reaches the guide assembly after passing through multiple traction stages. The blown film machine and the clamping assembly are existing technologies and are not shown in the figure.

[0052] In this embodiment, the guiding assembly is further configured to include a frame 21 and a guide roller 22. The bottom of the frame 21 is connected to the base plate. The guide roller is located at the top of the frame 21, and both ends of the guide roller are movably connected to the frame 21. The guide roller guides and flattens the passing film.

[0053] In this embodiment, the guide rollers are further arranged in an array at the top of the frame, and the guide rollers are provided with grooves 221, which are arranged in an array on the outer edge of the guide rollers.

[0054] In the present example, three guide rollers are provided, and the concave-convex groove has a flow guiding effect. When the uncooled film contacts the guide rollers, it is restricted to move along a specific path by the concave-convex groove, just like water flows in a river channel. The film is guided to move forward along the direction of the concave-convex groove, thereby realizing accurate control of the film flow direction, so that it is accurately conveyed to the next station according to the requirements of the production process, and has the effect of correcting deviation. At the same time, since the film has a certain plasticity when it is uncooled, under the action of the stretching force, the wrinkles or uneven parts that may exist are gradually flattened, so that the concave-convex groove has the effect of stretching and flattening.

[0055] In the present embodiment, the cooling assembly further comprises a rack two 31, a cooling roller 32 and a motor one 33. The bottom of the rack two is connected with the bottom plate. The cooling roller is located at the top of the rack two, and the two ends of the cooling roller are movably connected with the rack two, respectively. The cooling roller cools the passing film. The output end of the motor one is connected with one end of the cooling roller, and the motor one drives the cooling roller to rotate.

[0056] In the present example, the cooling roller is a prior art. When the film is extruded, it is usually at a high temperature and has a certain plasticity. The cooling roller can quickly take away the heat of the film by directly contacting the film and using the principle of heat conduction, so that the temperature of the film is rapidly reduced, the film is quickly shaped, and the film is prevented from sticking and deforming due to long time at a high temperature.

[0057] In the present embodiment, the cooling assembly further comprises a rack two 31, a cooling roller 32 and a motor one 33. The bottom of the rack two is connected with the bottom plate. The cooling roller is located at the top of the rack two, and the two ends of the cooling roller are movably connected with the rack two, respectively. The cooling roller cools the passing film. The output end of the motor one is connected with one end of the cooling roller, and the motor one drives the cooling roller to rotate.

[0058] In the present embodiment, the cooling assembly further comprises a rack two 31, a cooling roller 32 and a motor one 33. The bottom of the rack two is connected with the bottom plate. The cooling roller is located at the top of the rack two, and the two ends of the cooling roller are movably connected with the rack two, respectively. The cooling roller cools the passing film. The output end of the motor one is connected with one end of the cooling roller, and the motor one drives the cooling roller to rotate.

[0059] In the present example, the film moves along the winding direction under the action of the conveying roller. The conveying roller and the fixed roller have a gap for accommodating the passing film. When the film passes through the gap, it is extruded by the conveying roller and the fixed roller, so that the film is further flattened, and wrinkles are avoided.

[0060] In this embodiment, the adjustment assembly is further configured to include a slide rail 51, a cylinder 52, a frame 53, a sensor 54, a slider 55, a spring assembly 56, and an adjusting roller 57. The bottom of the slide rail is connected to the base plate, and a slide groove 511 is provided inside the slide rail. The slide rail has a pair of cylinders located between the two slide rails. The top of the frame 531 is provided with a slot 531, and the bottom sides of the frame 532 are provided with support plates 532, which are inserted into the slide grooves. One end of the bottom of the frame 532 is connected to the output end of the cylinder, and the cylinder drives the frame 532 to move along the direction of the slide groove. The sensor is fixedly installed at the bottom of the slot. The slider is inserted into the slot, and a through hole is provided in the middle of the slider. The top of the spring assembly is connected to the slider, and the bottom of the spring assembly is connected to the sensor. The two ends of the adjusting roller are movably connected to the slider.

[0061] In this example, two sets of adjustment components can be set. One set of adjustment components is higher than the winding component, and the other set of adjustment components is lower than the winding component. The adjustment components are used to keep the film in a taut state during the conveying process, which can smooth the film in time, prevent wrinkles and streaks, and ensure the balance of film tension.

[0062] In this embodiment, the winding assembly is further configured to include a frame 61, a winding roller 62, a motor 63, and a limiting plate 64. The bottom of the frame 61 is connected to the base plate. The winding roller is located at the top of the frame 61, and its two ends are movably connected to the frame 61. The winding roller receives and winds the film. The output end of the motor 63 is connected to one end of the winding roller, and the motor 63 drives the winding roller to rotate. The limiting plate is sleeved on the winding roller and limits the two ends of the film.

[0063] In this example, as the film passes the adjusting roller during the winding process, the film tension can be acquired in real time by a sensor. The sensor is an existing product that can be purchased directly from the market. As the film thickness on the winding roller increases, the pressure on the film increases, and the sensor feeds the signal back to the control unit. The control unit then uses a cylinder to drive the adjusting roller to move left and right along the film conveying direction, adjusting the distance between the adjusting roller and the winding roller to always ensure the balance of film tension and improve the flatness of the PE film winding.

[0064] Example 2:

[0065] In this embodiment, as Figure 4 As shown, based on Embodiment 1, the slide rail and cylinder can be replaced with a lead screw frame, a lead screw and a lead screw motor. A lead screw hole is provided at the bottom of the frame four. The lead screw passes through the lead screw hole, and both ends of the lead screw hole are connected to the lead screw frame. The output end of the lead screw motor is connected to the lead screw, and the frame four is driven to move by the lead screw motor.
