Abstract

This utility model provides a mixing and batching device for preparing plastic film, relating to the technical field of film batching devices. It includes a batching tank, with a discharge pipe fixedly installed on the left side of the lower end face of the tank. A cavity is formed inside the tank wall, and two inlet pipes are fixedly installed on the outer end face of the right side plate of the tank. In this utility model, a temperature sensor is located on the inner wall of the batching tank. The temperature sensor can monitor the temperature inside the tank in real time and feed the data back to the controller. When the temperature is lower than a set value, the controller can issue a command to improve the heating efficiency of the medium and increase the temperature of the heat-conducting medium. When the set value is reached, the heating power is automatically adjusted to maintain a constant temperature. This solves the problems of existing direct heating methods using electric heating wires, which not only result in large heat loss but also cannot dynamically adjust according to the material temperature, and the problem that some material adheres to the inner wall of the batching tank during mixing, affecting heat transfer.

Description

Technical Field

[0001] This utility model relates to the technical field of film batching devices, and in particular to a mixing and batching device for preparing plastic films. Background Technology

[0002] Plastic films have been widely used in food, medicine and daily necessities packaging, which have brought great convenience to people's lives. When plastic films are prepared, resin raw materials, additives, color masterbatches and other materials need to be mixed evenly in proportion. The mixing quality directly affects the mechanical properties, optical transparency and processing stability of the film.

[0003] However, existing film preparation mixing devices still have some shortcomings in use: First, existing heating medium circulation methods mostly involve direct heating with electric heating wires, which not only results in significant heat loss but also cannot be dynamically adjusted according to the material temperature, affecting the preparation effect.

[0004] Secondly, during the mixing of materials, some materials will adhere to the inner wall of the mixing tank, which will not only affect heat transfer, but also cause cross-contamination between different batches of materials. Utility Model Content

The two feed pipes 104 can respectively transport the main material and the auxiliary material, realizing the initial separation of feeding. Drive motor 2 is fixedly installed at the middle position of the outer end face of the right side plate of the mixing tank 1. The front end face of drive motor 2 is connected to drive shaft 201, and the end of drive shaft 201 is rotatably connected to the left side plate of mixing tank 1. Heater 3 is fixedly installed on the right side of the upper end face of the mixing barrel 1. A connecting pipe 301 is fixedly installed on the outer end face of the heater 3.

Controller 4 is fixedly installed on the upper surface of heater 3 and is electrically connected to heater 3.

[0021] The controller 4 has a connecting rod 401 fixedly installed on its outer end face, and a temperature sensor 4011 is fixedly installed at the end of the connecting rod 401. The temperature sensor 4011 is located on the inner wall surface of the mixing tank 1 and is electrically connected to the controller 4. The outlet end of the heating tube 3011 is fixedly connected to the heater 3. The heating tube 3011 is distributed in an S-shaped structure in the cavity 102. During use, the heater 3 is connected to the heating tube 3011 through the connecting tube 301. The heater 3 delivers the heated heat transfer medium to the inside of the S-shaped heating tube 3011. The heating tube 3011 is distributed in the cavity 102 of the mixing tank 1, forming a 360° heat radiation area around the tank wall, which is beneficial for uniform heating of the inside of the mixing tank 1. The outlet end of the heating tube 3011 is connected to the heater 3 to form a closed-loop circulation system, ensuring efficient heat utilization and reducing energy loss.

[0022] Among them, a blade 2011 is fixedly installed on the outside of the drive shaft 201. The blade 2011 has a spiral structure. The outer end face of the blade 2011 is in contact with the inner wall of the mixing tank 1. During use, when the spiral blade 2011 rotates with the shaft, it applies axial thrust and radial shear force to the material, so that the material inside the mixing tank 1 is fully mixed. The outer end face of the blade 2011 is in contact with the inner wall of the mixing tank 1 to scrape off the material attached to the tank wall, prevent local overheating or material accumulation, and enhance the exchange between the edge material and the center material.

Inside the heating tube 3011, the heating tubes 3011 are distributed in the cavity 102 of the mixing tank 1, forming a 360° heat radiation area around the tank wall, which is conducive to uniform heating of the inside of the mixing tank 1. The outlet end of the heating tube 3011 is connected to the heater 3, forming a closed-loop circulation system to ensure efficient heat utilization and reduce energy loss. The temperature sensor 4011 is located on the inner wall of the mixing tank 1. The temperature sensor 4011 can monitor the temperature inside the mixing tank 1 in real time and feed the data back to the controller 4. When the temperature is lower than the set value, the controller 4 can issue a command to increase the power of the heater 3, thereby improving the heating efficiency of the medium and increasing the temperature of the heat transfer medium. When the set value is reached, the heating power is automatically adjusted to maintain a constant temperature. After the material enters the mixing tank 1, the drive motor 2 is started. The drive motor 2 drives the drive shaft 201 to rotate. The spiral blades 2011 rotate with the shaft, applying axial thrust and radial shear force to the material, so that the material inside the mixing tank 1 is fully mixed. The outer end face of the blades 2011 is in contact with the inner wall of the mixing tank 1, scraping off the material adhering to the tank wall, preventing local overheating or material accumulation, and enhancing the exchange between the edge material and the center material. After the preparation is completed, the stopper plate 1031 is pulled out. The spiral blades 2011 continue to rotate to generate axial thrust, quickly discharging the material, thereby improving the unloading efficiency.
