Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of plastic particle feeding, in particular to a plastic particle uniform feeding device. Background Art
[0002] Film blowing machine is a machine that heats and melts plastic particles and then blows them into thin films. It is divided into many types such as PE, POF, PVC, etc. It is mainly composed of motor, screw, barrel, die head, etc. There are three important factors when the film blowing machine is working. One is temperature, including machine temperature and room temperature, the second is the spiral, and the third is the cooling system. The heating of the film blowing machine is currently mainly achieved by the friction between plastic particles and screw, plastic particles and barrel, collision friction of particle bonds and external heating of the barrel.
[0003] Film blowing is a plastic processing method that refers to a plastic processing technology that heats and melts plastic particles and then blows them into a film. It usually involves extruding a polymer into a tubular film blank, inflating the tube to the required thickness using high-pressure air under a good melt flow state, and then cooling and shaping it into a film.
[0004] The film blowing process requires a stable input of plastic particles. However, when the existing silo is evenly discharged, as the number of plastic particles in the silo decreases, the total weight of the plastic particles in the silo will decrease, resulting in a decrease in the amount of plastic particles discharged from the silo outlet. Although the change is not significant, it will reduce the pass rate when carrying out more complex plastic parts blown film production. Utility Model Content

[0025] Please refer to 1-5, a device for uniformly feeding plastic particles includes: a silo 1, a material distribution barrel 2 is fixedly connected to the lower end of the silo 1, a material distribution roller 5 is rotatably arranged in the material distribution barrel 2, six slidable baffles 53 are arranged in the material distribution roller 5, two material gathering plates 6 are symmetrically arranged in the material distribution barrel 2, a slider 62 is slidably arranged in the material gathering plate 6, and the outer edge of the baffle 53 is pressed against the slider 62.
[0026] Specifically, the utility model concentrates the plastic particles flowing down from the silo 1 through the gathering plate 6, and abuts the baffle 53 through the slider 62, so that when the dividing drum 5 rotates, the amount of plastic particles taken away per unit time is the same, thereby achieving no matter how much plastic particles are in the silo 1, but the amount of material discharged per unit time is exactly the same, thereby providing technical support for the production of better and more complex plastic parts. At the same time, since the slider 62 is slidably arranged in the gathering plate 6, a good buffer is formed between the dividing drum 5 and the gathering plate 6, thereby avoiding the occurrence of machine jams caused by plastic particles getting stuck between the dividing drum 5 and the gathering plate 6.
