Description

Technical Field

[0001] This utility model relates to the field of polyethylene film production technology, and in particular to a cooling and shaping device for polyethylene film production. Background Technology

[0002] Cooling and setting equipment for polyethylene film production is used to cool and reduce the temperature of polyethylene film to achieve a stable physical form and properties for subsequent processing and use.

[0003] Existing cooling and shaping devices for polyethylene film production have the following shortcomings: After the polyethylene film is extruded from the extruder, it adheres to the surface of the cooling roller. The cooling medium inside the cooling roller continuously circulates to absorb the heat transferred by the film for cooling and shaping. However, the surface flatness of the film itself is not good during the extrusion process, which makes it difficult to completely adhere to the roller surface and easily leaves gaps. This results in inconsistent local cooling rates of the film, which in turn causes the film to warp or have wavy edges.

[0004] Therefore, a cooling and shaping device for polyethylene film production is needed to solve the above problems. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments.

[0030] Example 1

[0031] Reference Figure 1 and Figure 2 This is the first embodiment of the present invention. This embodiment provides a cooling and shaping device for polyethylene film production, which can achieve the effect of flattening and cooling the film. It includes a film feeding mechanism 100 disposed on an extruder, and a water-cooled roller 101 disposed on the film feeding mechanism 100.

[0032] The pressing assembly 200 is disposed on the side wall of the film conveying mechanism 100. The pressing assembly 200 includes a pressing rod 202 and a lead screw 204.

[0033] The pressing rod 202 is located below the water-cooled roller 101 and is used to roll and limit the film. The lead screw 204 is located inside the film feeding mechanism 100 and is used to move the pressing rod 202.

[0034] The cleaning assembly 300 includes a cleaning component 301, which is disposed below the pressure bar 202 and is used to clean the pressure bar 202.

[0035] In use, by rotating the lead screw 204, the pressure rod 202 can be moved upward until the gap between the pressure rod 202 and the water-cooling roller 101 is suitable for the thickness of the film. At this time, the extruded film can be passed through the pressure rod 202 and multiple sets of water-cooling rollers 101 for cooling and shaping. The pressure rod 202 improves the adhesion of the film to the water-cooling roller 101, avoids gaps between the film and the roller surface, and prevents uneven cooling of the film, resulting in warping or wavy edges, thus improving the uniformity of film cooling.

[0036] Example 2

[0037] Reference Figures 1 to 4 This is the second embodiment of the present invention. Unlike the previous embodiment, the pressing assembly 200 also includes a shaft 201, which is rotatably connected to the inner wall of the pressing rod 202.

[0038] The shaft 201 has sliders 203 fixedly connected to both sides. The film feeding mechanism 100 has a corresponding groove 203a on one side. The sliders 203 are slidably connected inside the groove 203a. The lead screw 204 is rotatably connected inside the groove 203a. The sliders 203 are threadedly connected to the outer wall of the lead screw 204. The rotation of the two sets of lead screws 204 can drive the two sets of sliders 203 to slide upward. At the same time, the sliders 203 can drive the pressure rod 202 to move upward. This makes it easy to adjust the distance between the pressure rod 202 and the water-cooled roller 101 according to the thickness of the film, thus improving its applicability.

[0039] The film conveying mechanism 100 is internally connected to a connecting rod 207. Both ends of the connecting rod 207 are fixedly connected to a driving bevel gear 206, and the bottom of the lead screw 204 is fixedly connected to a driven bevel gear 205. The driving bevel gear 206 and the driven bevel gear 205 mesh with each other. The film conveying mechanism 100 is internally equipped with a motor and other driving components, and the output shaft of the motor is fixed to the connecting rod 207. The motor can drive the connecting rod 207 and the driving bevel gear 206 to rotate. At the same time, the two sets of driving bevel gears 206 can drive the driven bevel gear 205 and the lead screw 204 to rotate.

[0040] The cleaning component 300 also includes a vertical rod 302, which is fixedly connected to the bottom of the shaft 201. The cleaning component 301 is inserted into the bottom of the shaft 201. A fixing component 303 is threadedly connected to the bottom of the shaft 201, and the fixing component 303 abuts against the bottom of the cleaning component 301. A cleaning pad 301a is fixedly connected to the top of the cleaning component 301, and the cleaning pad 301a contacts the outer wall of the pressure rod 202. By inserting the cleaning component 301 into the bottom of the shaft 201 and fixing it by rotating the fixing component 303, the pressure rod 202 can be cleaned through the cleaning component 301. This avoids the surface of the pressure rod 202 from easily attracting dust due to static electricity, which would cause film contamination and improves the cleanliness of the film during cooling.

[0041] In use, the motor first drives the connecting rod 207 and the active bevel gear 206 to rotate. At the same time, the two sets of active bevel gears 206 can drive the passive bevel gear 205 and the lead screw 204 to rotate. The rotation of the two sets of lead screws 204 can drive the two sets of sliders 203 to slide upward. Then, the sliders 203 can drive the pressure rod 202 to move upward, so as to adjust the distance between the pressure rod 202 and the water-cooling roller 101 according to the thickness of the film. Finally, the extruded film can be passed through the pressure rod 202 and multiple sets of water-cooling rollers 101 for cooling and shaping.

[0042] The specific functions and principles of the film feeding mechanism 100 and the water-cooled roller 101 on the extruder can be found in the film feeding extruder model XH-432.

[0043] It should be understood that numerous specific implementation decisions can be made during the development of any actual implementation method, and in any engineering or design project. Such development efforts may be complex and time-consuming, but for those of ordinary skill in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
