Description

Technical Field

[0001] The utility model relates to the technical field of processing equipment, in particular to a cast film machine. Background Art

[0002] Cast film is a non-stretched, non-directional flat extruded film produced by melt casting and cooling. Compared with blown film, it is characterized by fast production speed, high output, good film gloss and uniform thickness. As a type of cast film, CPE film is a flat extruded film, which is very convenient for subsequent processes such as printing and lamination. Therefore, it is widely used in the packaging of textiles, industry, food, daily necessities, etc.

[0003] A Chinese patent (authorization announcement number: CN 206937774 U, authorization announcement date: 2018.01.30) proposes an automatic feeding cast film machine. By sealing the feed hopper and connecting it to a suction pipe, a negative pressure is generated in the feed hopper during operation. At this time, the raw material will enter the feed hopper through the suction pipe under the action of the negative pressure.

[0004] The existing film raw material particles are more or less mixed with large particles. Once the large particles are not completely melted, the qualified rate of the film will be greatly affected. In addition, the controllability of the above-mentioned device for feeding by negative pressure is not high, and it is impossible to feed the cast film machine at a uniform speed. In order to solve the problem of large particle raw materials affecting the quality of the film, we propose a cast film machine. Utility Model Content

The screw conveyor 27 is connected with the storage bin 8 through the discharge port 17, and a stirring and crushing component is installed on the storage bin 8. A quantitative feeding component is installed between the storage tank 4 and the connecting tube 30.

[0031] When the device is in use, workers add film raw materials into the storage bin 8, and stir and crush the film raw materials through the stirring and crushing component to prevent large particles in the raw materials from affecting the quality of the film. The crushed raw materials are then transported to the storage tank 4 through screw conveyor 1 5 and screw conveyor 2 7. The raw materials transported to the storage tank 4 are fed at a uniform speed through the quantitative feeding component. Since each conveying mechanism is controlled by the controller 9, and a material level sensor 1 27 and a material level sensor 2 28 are set on the storage tank 4, when the raw material in the storage tank 4 is higher than the material level sensor 1 27, the screw conveyor 1 5 and the screw conveyor 2 7 are turned off. Conversely, when the raw material in the storage tank 4 is higher than the material level sensor 1 27, the screw conveyor 1 5 and the screw conveyor 2 7 are turned on. When the raw material in the storage tank 4 is lower than the material level sensor 2 28, the conveying speed of the screw conveyor 1 5 and the screw conveyor 2 7 is accelerated. Infrared transmitters 14 and infrared receivers 15 are respectively provided on the left and right side walls of the storage bin 8. When the raw material in the storage bin 8 is too low, an alarm 12 is used to warn workers to add materials.

[0032] The mixing and crushing assembly includes a mounting plate 10, on which a drive motor 11 is fixedly mounted. The output shaft end of the drive motor 11 passes through the mounting plate 10 and is fixedly connected to a rotating rod 32, and the other end of the rotating rod 32 is fixedly connected to a first bevel gear 18.

[0033] A filter plate 16 is fixedly installed on the bottom side of the inner wall of the storage bin 8. A number of rotating seats 21 are also fixedly connected to the inner wall of the storage bin 8. The rotating seats 21 are located above the filter plate 16, and a crushing roller 20 is rotatably installed on the rotating seats 21. The other end of the crushing roller 20 is fixedly connected to a second bevel gear 19, which is engaged with the first bevel gear 18.

[0034] The outer surface of the rotating rod 32 is provided with a plurality of spline grooves 34, and the outer surface of the rotating rod 32 is also provided with a lifting sleeve 22. The outer surface of the lifting sleeve 22 is fixedly connected to a plurality of stirring blades 13, and the inner wall of the lifting sleeve 22 is fixedly connected to a plurality of splines 33, which are slidably connected to the spline grooves 34.

[0035] A limiting sleeve 24 is provided on the top side of the lifting sleeve 22. The top end of the limiting sleeve 24 is fixedly connected to the bottom side of the mounting plate 10.

The limiting rod 23 is slidably connected to the annular groove 25.

[0036] When the mixing and crushing assembly is in use, the drive motor 11 is started, the rotating rod 32 is driven by the drive motor 11, and the second bevel gear 19 is engaged with the first bevel gear 18, thereby driving the crushing roller 20 to rotate and crush the raw materials. Since the spline 33 on the lifting sleeve 22 is slidably connected to the spline groove 34 on the rotating rod 32, the lifting sleeve 22 is driven to rotate, and the stirring blade 13 is driven to stir the raw materials. Moreover, since the limit rod 23 on the top side outer surface of the lifting sleeve 22 is slidably connected to the annular groove 25 opened in the limit sleeve 24, the lifting sleeve 22 is lifted and lowered back and forth while rotating, so that the raw materials in the storage bin 8 are evenly mixed.

[0037] The quantitative feeding assembly includes a second drive motor 29 , which is fixedly mounted on the left side of a connecting cylinder 30 . The output shaft end of the second drive motor 29 passes through the connecting cylinder 30 and is fixedly connected to a roller 31 .

[0038] The quantitative feeding component drives the roller 31 to rotate through the driving motor 29, and controls the feeding speed by controlling the rotation speed of the roller 31.

[0043] Working principle: When the device is used, the worker adds the film raw material into the storage bin 8, drives the rotating rod 32 by starting the driving motor 11, and engages the first bevel gear 18 through the second bevel gear 19, thereby driving the crushing roller 20 to rotate and crush the raw material. Since the spline 33 on the lifting sleeve 22 is slidably connected to the spline groove 34 on the rotating rod 32, the lifting sleeve 22 is driven to rotate, and the stirring blade 13 is driven to stir the raw material. Since the limiting rod 23 on the top side outer surface of the lifting sleeve 22 is slidably connected to the annular groove 25 provided on the limiting sleeve 24, the lifting sleeve 22 is lifted and lowered back and forth while rotating, so that the raw materials in the storage bin 8 are evenly mixed. The setting of the stirring blade 13 and the crushing roller 20 prevents large particles in the raw materials from affecting the quality of the film. Then the crushed raw materials are passed through the screw conveyor 5 and the screw conveyor The raw materials are transported to the storage tank 4 by the second 7, and the roller 31 is driven to rotate by the driving motor 29, and the unloading speed of the storage tank 4 is controlled by controlling the rotation speed of the roller 31. Since each conveying mechanism is controlled by the controller 9, and a material level sensor 1 27 and a material level sensor 2 28 are set on the storage tank 4, when the raw materials in the storage tank 4 are higher than the material level sensor 1 27, the screw conveyor 1 5 and the screw conveyor 2 7 are turned off. On the contrary, when the raw materials in the storage tank 4 are higher than the material level sensor 1 27, the screw conveyor 1 5 and the screw conveyor 2 7 are turned on. When the raw materials in the storage tank 4 are lower than the material level sensor 2 28, the conveying speed of the screw conveyor 1 5 and the screw conveyor 2 7 is accelerated. Infrared transmitters 14 and infrared receivers 15 are respectively set on the left and right side walls of the storage bin 8. When the raw materials in the storage bin 8 are too low, an alarm 12 is used to warn workers to add materials.
