Description

Technical Field

[0001] The utility model relates to the technical field of winding film manufacturing, in particular to a device for manufacturing a light-degradable polymer PE winding film. Background Art

[0002] Photodegradable polymer PE wrapping film is a plastic packaging material designed to be gradually decomposed under outdoor conditions. This material is added with photodegradable additives, which can accelerate the breakage of molecular chains after being exposed to ultraviolet light, thereby promoting the decomposition of the material and reducing environmental pollution.

[0003] When processing and manufacturing the photodegradable polymer PE stretch film, the molten raw material is extruded through the die head of the extruder, then quickly cooled on a cooling roller to form a film, and then pulled and rolled around a guide cylinder to adjust the uniformity of the overall thickness of the photodegradable polymer PE stretch film. During the pulling and rolling process, photodegradable polymer PE stretch films of different thicknesses require different pulling tensions, and existing photodegradable polymer PE stretch film manufacturing equipment cannot adjust the pulling tension according to the manufacturing requirements of the photodegradable polymer PE stretch film, resulting in quality problems of the manufactured photodegradable polymer PE stretch film.

[0004] In order to solve the above problems, we propose a photodegradable polymer PE stretch film manufacturing equipment, which can adjust the pulling tension according to the manufacturing requirements of the photodegradable polymer PE stretch film. Utility Model Content

[0005] In order to overcome the shortcoming that the existing manufacturing equipment cannot adjust the pulling tension according to the manufacturing requirements of the photodegradable polymer PE stretch film, the technical problem to be solved is: to provide a photodegradable polymer PE stretch film manufacturing equipment.

[0006] The utility model is implemented through the following technical means: a photodegradable polymer PE winding film manufacturing device, including a mounting frame, an extruder is fixedly connected to the mounting frame, a suction pipe is connected to the extruder, a cooling roller is fixedly connected to the mounting frame, a water inlet is connected to the cooling roller, a longitudinally symmetrical sliding tube is slidably connected to the mounting frame, a first film pulling cylinder is rotatably connected between the longitudinally symmetrical sliding tubes, a connecting frame is fixedly connected to the sliding tube on one side, a threaded rod is rotatably connected to the side of the mounting frame close to the connecting frame, and the threaded rod is connected to the connecting frame by threads.

[0007] As an improvement of the above solution, a rotating handle is fixedly connected to the bottom end of the threaded rod.

[0008] As an improvement of the above scheme, it also includes a longitudinally symmetrical sliding rod, the longitudinally symmetrical sliding rod is slidably connected in the sliding tube, a second film-pulling cylinder is rotatably connected between the longitudinally symmetrical sliding rods, an elastic member is connected between the sliding rod and the adjacent sliding tube, a mounting plate is fixedly connected to the mounting frame, a sensor is fixedly connected to the mounting plate, an alarm is fixedly connected to the mounting frame, and the alarm is electrically connected to the sensor.

[0009] As an improvement of the above scheme, it also includes a longitudinally symmetrical installation frame, which is fixedly connected to the installation rack, and a vertically symmetrical guide wheel is rotatably connected inside the installation frame.

[0010] As an improvement of the above solution, it also includes a longitudinally symmetrical cooling fan, which is fixedly connected to the mounting frame.

[0011] As an improvement of the above solution, a filter screen is also included, and the filter screen is fixedly connected to the bottom end of the suction pipe.

[0012] The utility model has the following advantages: 1. The extruder extrude the molten raw material onto the cooling roller for cooling and forming, and then the molten raw material is guided to the right around the upper side of the first film-pulling cylinder for winding. When the first film-pulling cylinder pulls and guides the photodegradable polymer PE stretch film, the height of the first film-pulling cylinder is adjusted by rotating the threaded rod, thereby adjusting the pulling tension of the first film-pulling cylinder on the photodegradable polymer PE stretch film.

[0013] 2. The photodegradable polymer PE stretch film passes through the first film-pulling cylinder and the second film-pulling cylinder. During the moving and conveying process, the thickness difference of the photodegradable polymer PE stretch film will cause the second film-pulling cylinder to move up and down. The sensor monitors the up and down movement distance range of the second film-pulling cylinder. When the up and down movement distance of the second film-pulling cylinder is too large, the alarm will sound to alert the staff.

[0014] 3. The photodegradable polymer PE stretch film transported to the right is guided for a second time by the installation frame and guide wheels to avoid wrinkles of the photodegradable polymer PE stretch film, while the cooling fan can perform secondary cooling to ensure that the photodegradable polymer PE stretch film is shaped for winding.

DETAILED DESCRIPTION

[0021] The above scheme is further described below in conjunction with specific examples. It should be understood that these examples are used to illustrate the present application and are not limited to the scope of the present application. The implementation conditions adopted in the examples can be further adjusted according to the conditions of the specific manufacturer, and the implementation conditions not specified are usually the conditions in conventional experiments.

[0022] Embodiment 1: A photodegradable polymer PE wrapping film manufacturing device, such as Figure 1 and Figure 2 As shown, it includes a mounting frame 1, an extruder 2, a suction pipe 3, a water inlet 4, a cooling roller 5, a first film-pulling cylinder 6, a sliding tube 61, a connecting frame 7 and a threaded rod 8. The extruder 2 is fixedly connected to the left side of the mounting frame 1, the suction pipe 3 is connected to the left side of the extruder 2, the cooling roller 5 is fixedly connected to the lower left part of the mounting frame 1, the front side of the cooling roller 5 is connected to the water inlet 4, the upper left part of the mounting frame 1 is slidingly connected to the front and rear symmetrical sliding tubes 61, the first film-pulling cylinder 6 is rotatably connected between the front and rear sliding tubes 61, the front sliding tube 61 is fixedly connected to the connecting frame 7, the front left part of the mounting frame 1 is rotatably connected to the threaded rod 8, the bottom end of the threaded rod 8 is fixedly connected to a turning handle, and the threaded rod 8 is connected to the connecting frame 7 by threads.

[0023] When using the device, the suction pipe 3 sucks the raw material into the extruder 2, and the extruder 2 extrude the raw material onto the cooling roller 5. After the photodegradable polymer PE stretch film is cooled and formed, it bypasses the lower side of the cooling roller 5, and then bypasses the upper side of the first film-pulling cylinder 6 to be transported to the right for winding. The coolant can enter the cooling roller 5 through the water inlet 4 to ensure the cooling effect. When the first film-pulling cylinder 6 pulls and guides the photodegradable polymer PE stretch film, the staff can control the rotation of the threaded rod 8 according to the manufacturing requirements of the photodegradable polymer PE stretch film. The rotation of the threaded rod 8 drives the sliding tube 61 to slide up and down through the connecting frame 7. The sliding tube 61 slides up and down and drives the first film-pulling cylinder 6 to move up and down to adjust the height, thereby adjusting the pulling tension of the first film-pulling cylinder 6 on the photodegradable polymer PE stretch film.

[0024] Embodiment 2: Based on embodiment 1, Figure 1 and Figure 3 As shown, it also includes a second film-pulling cylinder 9, a sliding rod 91, an elastic member 10, a mounting plate 11, a sensor 12 and an alarm 13. The sliding rod 91 is slidably connected in the sliding tube 61, and the second film-pulling cylinder 9 is rotatably connected between the front and rear sliding rods 91. The elastic member 10 is connected between the sliding rod 91 and the adjacent sliding tube 61. The mounting plate 11 is fixedly connected to the left front portion of the upper side of the mounting frame 1, and the sensor 12 is fixedly connected to the mounting plate 11. The alarm 13 is fixedly connected to the lower right portion of the front side of the mounting frame 1, and the alarm 13 is electrically connected to the sensor 12.

[0025] When using the device, the photodegradable polymer PE stretch film will also stick to the lower side of the second film-pulling cylinder 9 when it passes around the upper side of the first film-pulling cylinder 6. In the process of the photodegradable polymer PE stretch film moving to the right, the thickness difference of the photodegradable polymer PE stretch film will cause the second film-pulling cylinder 9 to move up and down, and the sliding rod 91 will slide up and down accordingly, and the elastic part 10 will deform and reset. The sensor 12 is used to monitor the distance range of the second film-pulling cylinder 9 moving up and down. When the up and down movement distance of the second film-pulling cylinder 9 is too large, it means that there is a big problem with the thickness uniformity of the photodegradable polymer PE stretch film, and the alarm 13 will sound an alarm to alert the staff.

[0026] like Figure 1 and Figure 4 As shown, it also includes a mounting frame 14 and guide wheels 15. The upper right part of the mounting frame 1 is fixedly connected to a front-to-rear symmetrical mounting frame 14, and a row of guide wheels 15 symmetrical up and down are rotatably connected inside the mounting frame 14.

[0027] When the device is used, the photodegradable polymer PE wrapping film transported to the right passes through the front and rear mounting frames 14 and is secondary guided by the guide wheel 15 to prevent the photodegradable polymer PE wrapping film from wrinkling.

[0028] like Figure 1 and Figure 4 As shown, a cooling fan 16 is also included, and the upper part of the mounting frame 1 is fixedly connected to the cooling fan 16 which is symmetrical in front and back.

[0029] When the device is used, the cooling fan 16 can cool the photodegradable polymer PE wrapping film again to ensure that the photodegradable polymer PE wrapping film is shaped for winding.

[0030] like Figure 5 As shown, a filter screen 17 is also included, and the lower part of the suction pipe 3 is fixedly connected with the filter screen 17.

[0031] When the device is used, the filter screen 17 can filter the raw materials sucked by the suction pipe 3 to prevent the raw materials from being completely melted and affecting the manufacturing quality of the photodegradable polymer PE wrapping film.

[0032] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
