Technical Field

The invention relates to the technical field of plastic film production and processing, and in particular to a raw material stirring device used for plastic film production.

Background Art

With the development of economy, plastic film is widely used in life, and there are multiple processes in the production process of plastic film. First of all, a granulator is needed in the production and preparation process of plastic film. Generally, a feed hopper is directly set at the upper end of the barrel of the granulator, and then the material is directly put into the feed hopper, and falls into the barrel by gravity. Then the raw material is melted into liquid material by heating mechanism, and then processed into strip material by extrusion molding mechanism, and finally made into granular material by shearing mechanism.

The current raw material stirring device is prone to uneven mixing when mixing multiple raw materials, and the materials are prone to adhere to the inner wall of the hopper during heating and stirring, which is difficult to remove, so there is a need for improvement.

Summary of the invention

The above technical problems of the present invention are solved by the following technical solutions: a raw material stirring device for plastic film production, comprising a stirring bracket, a stirring barrel is provided on the stirring bracket, a plurality of raw material barrels are mounted above the stirring barrel, a mixing barrel is provided on the top of the stirring barrel, the raw material barrel is connected to the mixing barrel through a conveying pipe, a plurality of mixing and stirring rods are provided in the mixing barrel, and a discharge port is provided on one side of the bottom of the stirring barrel; a mixing motor is provided on the top of the mixing barrel, a driving shaft is installed on the mixing motor extending downward, the mixing and stirring rods are installed on the driving shaft, a plurality of linkage cross bars are symmetrically provided at the bottom of the driving shaft, a scraper is fixedly provided at the end of each linkage cross bar, and the scraper is against the inner wall of the stirring barrel. During operation, the number of raw material barrels can be adjusted according to demand. The utility model takes two raw material barrels as an example for explanation. Different raw materials are stored in the two raw material barrels respectively. The unmixed raw materials in the two raw material barrels will be transported to the mixing barrel along the conveying pipe. The mixing and stirring rod in the mixing barrel fully mixes the two raw materials. The mixed materials fall into the mixing barrel and are stirred again before being discharged. The function of the mixing motor is to provide power for the rotation of the driving shaft and the mixing and stirring rod. The mixing motor can drive the driving shaft and the mixing and stirring rod to rotate in the mixing barrel. The linkage cross bar is fixed at the bottom of the driving shaft, and the linkage cross bar can rotate synchronously with the mixing and stirring rod. The scraper on the linkage cross bar is attached to the inner wall of the mixing barrel, and the scraper will continuously scrape off the raw materials adhered to the inner wall of the raw material barrel to avoid the accumulation of raw materials adhered to the inner wall of the raw material barrel.

Preferably, the mixing barrel is an open-bottomed barrel. The top of the mixing barrel is sealed and the bottom is open. The unmixed raw materials in the raw material barrel are transported to the mixing barrel along the conveying pipe. The mixing and stirring rod in the mixing barrel fully mixes the raw materials, making it easier for the raw materials to fall into the stirring barrel.

Preferably, the scraper is fixed obliquely on the linkage cross bar, and the scraper is attached to the inner wall of the mixing barrel. The inclined scraper can well scrape off the raw materials adhering to the inner wall of the mixing barrel, and can prevent the raw materials from adhering to the scraper.

Preferably, the mixing barrel is symmetrically provided with feeding belts on both sides. A feeding belt is installed on the outer side of each mixing barrel, and when working, the feeding belt transports the raw materials to be mixed upward into the raw material barrel.

Preferably, the mixing and stirring rod is an obliquely installed stirring rod, which can slow down the falling speed of the raw materials while mixing two or more raw materials.

Preferably, the bottom of the mixing barrel is provided with a plurality of raw material stirring rods, which are driven by a stirring motor fixed at the bottom of the mixing barrel. The stirring motor can drive the raw material stirring rods to rotate at the bottom of the mixing barrel, and can fully stir the mixed raw materials.

Preferably, a heating plate is embedded in the inner wall of the mixing barrel. The heating plate can be turned on as needed to heat the inside of the mixing barrel to ensure that the raw materials are mixed and stirred sufficiently.

Therefore, the raw material stirring device for plastic film production of the present invention has the following advantages: two or more raw materials can be fully mixed during feeding, ensuring that the raw materials can be fully heated and stirred after mixing, and preventing the raw materials from accumulating and adhering to the inner wall of the stirring barrel after heating.
