Description

Technical Field

[0001] The utility model relates to the technical field of mixing devices, in particular to a raw material mixing device for uniformly stirring film production. Background Art

[0002] Film is a commonly used flexible packaging material with the characteristics of good stretchability and high transparency. The main raw material of the film is polypropylene. In the actual production process, polypropylene and additives need to be mixed into a masterbatch in a certain proportion, and then subsequent processing is carried out. At present, the raw materials are mainly mixed by a mixing device. Announcement No.: CN219765085U discloses a fertilizer raw material mixing device, including a fertilizer raw material receiving barrel, a support frame is installed on the top of the fertilizer raw material receiving barrel, and an assembly through groove is arranged at the middle end of the support frame, and an adjustment groove is arranged on the outer surface of the support frame, a straight plate is installed in the adjustment groove, and a through hole is opened on the straight plate, a limit rod is installed on the outer surface of the straight plate, and the limit rod is connected to the support frame, and a support spring is installed on the outer side of the limit rod, and the support spring is located inside the adjustment groove, and an operating rod is installed through the support frame. The fertilizer raw material mixing device can block and partition the assembly slot through a straight plate, and the elastic force of the support spring pushes the straight plate to maintain the stability of the partition. The positioning can be released by moving the through hole on the straight plate, which is convenient for the subsequent disassembly of the operating rod, and maintenance, cleaning and removal can be carried out. However, during the use of the above technology, the interior of the storage barrel does not have a structure to prevent materials from hanging on the wall, so that part of the stirred materials will adhere to the inner wall of the storage barrel after being discharged from the storage barrel. In the long run, more and more materials will adhere to the inner wall of the storage barrel, which is not conducive to the subsequent stirring and mixing of the materials and the cleaning of the inner wall of the storage barrel.

A discharge pipe 24 is fixedly connected to the bottom of the stirring barrel 3, and a valve 25 is fixedly connected to the surface of the discharge pipe 24. Here, the fully mixed materials can be discharged from the inner barrel through the discharge pipe 24.

[0024] Embodiment Two

[0025] Please refer to Figures 1-5 , a support leg 2 is fixedly connected to the lower surface of the base 1, and an anti-slip pad 10 is fixedly connected to the bottom surface of the support leg 2. Here, the friction between the support leg 2 and the ground can be increased, avoiding the mixing device from shifting relative to the ground due to the vibration generated when the output end of the motor 5 drives the cylindrical rod 6 and the stirring rod 7 to rotate. An output end of the motor 5 is fixedly connected to a fixing block 11, a jack 12 is formed on the surface of the fixing block 11, a U-shaped clamping block 13 is fixedly connected to one end of the cylindrical rod 6, a second round hole 26 is formed on the surface of the U-shaped clamping block 13, the fixing block 11 is inserted into the groove of the U-shaped clamping block 13, a first bolt 14 is inserted inside the jack 12 and the second round hole 26, and the other end of the first bolt 14 is threadedly connected to a nut 15.

[0026] Working principle: During use, first place the material in the mixing barrel 3, and then start the motor 5. The output end of the motor 5 drives the cylindrical rod 6 to rotate. While the cylindrical rod 6 rotates, it drives the stirring rod 7 and the connecting rod 8 to rotate to stir the material in the mixing barrel 3. When the material is fully and evenly stirred, open the valve 25 on the discharge pipe 24 to discharge the material from the discharge pipe 24. After all the material in the mixing barrel 3 has flowed out of the discharge pipe 24, start the motor 5 again. While the output end of the motor 5 rotates, it drives the cylindrical rod 6, the connecting rod 8, and the scraper 9 to rotate again to scrape the residual material on the inner wall of the mixing barrel 3. And the scraper 9 always keeps in contact with the inner wall of the mixing barrel 3 under the action of the T-shaped block 18 and the spring 19, realizing the scraping of the material on the inner wall of the mixing barrel 3, avoiding the phenomenon of material sticking to the wall during the mixing and stirring process and after discharging from the inner barrel, keeping the inner wall of the used mixing barrel 3 clean and tidy, and at the same time avoiding the influence of the residual material on the inner wall of the inner barrel on the next material mixing work. By setting the T-shaped block 18 and the spring 19, the scraper 9 always keeps in contact with the inner wall of the mixing barrel 3. When the mixing device is used for a long time, if the motor 5 fails, at this time, unscrew the nut 15 from the first bolt 14, then pull out the first bolt 14 from the inside of the fixed block 11 and the U-shaped clamping block 13, and then remove the motor 5 from the support frame 4 and repair or replace the motor 5. It realizes the connection between the output end of the motor 5 and the cylindrical rod 6, and at the same time facilitates the disassembly and assembly of the output end of the motor 5 and the cylindrical rod 6, facilitating the repair or replacement of the faulty motor 5 in the later stage.
