Abstract
Description
Technical Field
[0001] This utility model relates to the field of shrink film production technology, and in particular to a shrink film raw material particle mixing device. Background Technology
[0002] Shrink film is mainly used for the outer packaging of products. It has the functions of stabilizing, covering and protecting products. It tightly packages objects by pre-stretching and shrinking them by heat. Before shrink film production, the raw material particles used to produce shrink film need to be mixed by a mixer to ensure the quality of the shrink film output.
[0003] When mixing shrink film raw material particles, existing mixers first pour the shrink film particles directly into the mixer. This method results in extremely uneven distribution of different types of raw materials. Furthermore, when mixing the molten shrink film raw material, the existing mixing mechanism moves along with the mixing blades. This means that the mixing blades do not move relative to the molten shrink film raw material, resulting in an unsatisfactory mixing effect.
[0004] To address the issues that the direct pouring method results in uneven distribution of different types of raw materials and unsatisfactory mixing effects due to the melting shrink film material moving with the mixing blades, a mixing device is designed that can break up the shrink film material during the pouring process and allow the mixing blades to move up and down during mixing to overcome these problems. Utility Model Content
[0005] To overcome the problems that directly pouring raw materials into the mixer would result in extremely uneven distribution of different types of raw materials and that the molten shrink film material would move with the mixing blades, leading to an unsatisfactory mixing effect.

[0010] Preferably, a connecting shaft is fixedly installed at the lower end of the dispersion box, and stirring blades are slidably connected to both sides of the connecting shaft. The stirring blades are used to stir and mix the molten shrinkage material in the heating chamber.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0023] Please see Figure 1 - Figure 7 This utility model provides an embodiment: a shrink film raw material particle mixing device, including a heating chamber 1, an upper shell 9 and a stirring blade 14. The upper shell 9 is fixedly installed at the upper end of the heating chamber 1. The stirring blade 14 is provided inside the heating chamber 1. The upper shell 9 is provided with a stirring component for dispersing and stirring the shrink film raw material. The upper end of the stirring blade 14 is provided with a lifting component for raising and lowering the stirring blade 14.
[0024] Please see Figure 2 and Figure 6 In this embodiment, a heater 2 is fixedly installed on one side of the heating chamber 1. The heater 2 is used to heat and melt the shrink film material in the heating chamber 1. A control panel 3 is fixedly installed on one side of the heater 2. A connecting pipe 8 is fixedly connected to one side of the upper shell 9. One end of the connecting pipe 8 passes through the upper shell 9. A blower 7 is fixedly installed at one end of the connecting pipe 8. A feed pipe 6 is fixedly connected to the upper end of the connecting pipe 8. A feed interface 4 is fixedly installed at the upper end of the feed pipe 6. A discharge port 5 is fixedly installed at the lower end of one side of the heating chamber 1. A ventilation hole is provided on the upper side of the heating chamber 1. A motor 10 is fixedly installed at the upper end of the upper shell 9. A stirring rod 11 is fixedly installed at the lower end of the output shaft of the motor 10. The stirring rod 11 is located inside the upper shell 9. A dispersion box 12 is fixedly installed at the lower end of the stirring rod 11. Openings are evenly distributed on the surface of the dispersion box 12. The stirring rod 11 is used to disperse the shrink film material. The dispersion box 12 is used to separate the shrink film material in various directions.
[0025] Please see Figure 4 , Figure 5 and Figure 7 In this embodiment, a connecting shaft 13 is fixedly installed at the lower end of the dispersion box 12. Agitating blades 14 are slidably connected to both sides of the connecting shaft 13. The agitating blades 14 are used to agitate and mix the molten shrinkage material in the heating chamber 1. Rollers 15 are rotatably connected to both ends of the agitating blades 14. The heating chamber 1 has undulating protrusions. The rollers 15 move undulatingly on the protrusions in the heating chamber 1. The connecting shaft 13 has a slot. A spring 16 is provided in the slot of the connecting shaft 13. A locking block is provided in the center of the agitating blades 14. The locking block of the agitating blades 14 slides in the slot of the connecting shaft 13. The spring 16 is used to push the locking block on the agitating blades 14.
[0026] During use, the conveying pipe for transporting the shrink film material is first connected to the feed port 4. The control panel 3 is then used to start all equipment. After the blower 7 is turned on, a pressure difference is generated inside the upper shell 9 due to the airflow. The shrink film material is drawn into the upper shell 9 by the airflow due to the pressure difference and falls into the heating chamber 1. As the shrink film material passes through the upper shell 9, the motor 10 drives the stirring rod 11 to disperse and mix the material. The dispersed and mixed material then falls into the lower dispersion box 12. The motor 10 drives the dispersion box 12 to rotate rapidly. Due to centrifugal force, the shrink film material in the dispersion box 12 flows out from the evenly distributed openings on the surface of the dispersion box 12. The airflow generated by the blower 7 also flows out from the openings of the dispersion box 12. Thus, under the blowing of the airflow... The shrink film material in the dispersion box 12 will not be blocked. After being separated by the dispersion box 12, the shrink film material will be evenly distributed in the heating chamber 1. Compared with the traditional direct pouring and mixing, the distribution of the shrink film material will be more uniform. The heater 2 heats and melts the shrink film material in the heating chamber 1. During the process of the motor 10 driving the connecting shaft 13 to rotate, the stirring blade 14 stirs and mixes the shrink film material. At the same time, the roller 15 at the end of the stirring blade 14 moves up and down on the undulating protrusion on the inner wall of the heating chamber 1. In this way, the stirring blade 14 moves up and down at the same time. During the stirring process, the melted shrink film material is broken up longitudinally to prevent the melted shrink film material from moving with the stirring blade 14, which would result in an unsatisfactory stirring effect. After the stirring is completed, the shrink film material is discharged from the discharge port 5 to enter the next process.
[0027] Through the above steps, the device can break up and mix the shrink film material during the pouring process. The broken up and mixed shrink film material is then further evenly distributed in the heating chamber 1 by centrifugation, thereby avoiding the problem of uneven material distribution. During stirring, the stirring blade 14 moves up and down at the same time, thereby breaking up the molten shrink film material longitudinally and preventing the molten shrink film material from moving with the stirring blade 14, thus ensuring the mixing effect.
[0028] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
