Description

Technical Field

[0001] The invention belongs to the technical field of polystyrene production, and in particular relates to multi-directional stirring equipment for polystyrene production. Background Art

[0002] With the rapid development of modern material technology, people have discovered plastics that are light and easy to use. Generally speaking, plastics refer to polystyrene materials. Polystyrene is easy to process and has the advantages of transparency, cheapness, rigidity, insulation, and good printability. It can be widely used in the light industry market, daily decoration, lighting instructions and packaging. In terms of electricity, it is a good insulating material and heat-insulating material. It can be used to make various instrument housings, lampshades, optical chemical instrument parts, transparent films, capacitor dielectric layers, etc. In the processing of polystyrene, it is necessary to stir the liquid polystyrene constantly to prevent the particles from condensing. The existing halving structure does not stir evenly. It only uses the rotation of the transmission to stir. The liquid polystyrene has strong viscosity and coagulation. This will cause the traditional rotary stirring to easily appear in the four corners or the stirring is not uniform, resulting in local coagulation or local failure to meet the pretreatment requirements and forced to be exported, which affects the quality of product molding. In addition, there is no better structure that can meet the full stirring and self-cleaning effect at the same time, which makes it a big problem to clean the stirring rod after full stirring.

This can be achieved by using springs of different lengths, from After the rebound, the temporary storage tank becomes larger and larger from top to bottom. At this time, when the stirring shaft drives the stirring element to rotate, the centrifugal force can be used to throw the material to the temporary storage tank. Then, the stirring element is set obliquely downward, and the residue thrown to the temporary storage tank can be used at the same time; the centrifugal force continues to slide downward until it is taken over by the temporary storage tank of the next stirring element. This can facilitate the next one to take over by making the previous temporary storage tank smaller than the next temporary storage tank, and the material on the stirring element will not be thrown to the opposite inner wall by the centrifugal force, so that the whole cleaning process is very smooth and there will be no residue, and the cleaning is cleaner.

[0035] Working principle: Embodiment 1: When using the present invention, by closing the transmission box 1 2 and then inserting the limit assembly 204, the stirring shaft 6 inside the heat-insulating shell 1 and the driven paper wheel disc 203 are rotated synchronously on the circumference, and the motor 1 205 and the motor 2 504 are started at the same time, respectively driving the gear ring 1 202 and the gear ring 2 502 to rotate, thereby driving the stirring shaft 6 to make a circumferential revolution in the heat-insulating shell 1, and the gear ring 2 502 drives the synchronous ring 9 and the stirring shaft 6 fixed on the top of the synchronous ring 9 to rotate, so as to realize the upper and lower power source output of the stirring shaft 6 to prevent the sticky power output at one end of the stirring material from affecting the stability of the stirring shaft 6, and then the gear ring 1 202 is used to drive the driven paper wheel disc 203 to rotate synchronously. The paper wheel 203 is driven to move so that the stirring shaft 6 rotates while the stirring shaft 6 revolves around the heat-insulating shell 1, thereby achieving an overall stirring effect. Then, by utilizing the setting of multiple stirring members 7 on the stirring shaft 6, when the stirring shaft 6 rotates counterclockwise, multiple spirally arranged stirring members 7 can be used to form a spiral conveying state, continuously pushing materials upward. At the same time, the shape setting of the stirring members 7 can be used to continuously scrape and remove adhesion on the inner wall of the heat-insulating shell 1, and then the setting of the arc plate is used to guide the pushed-up materials to the middle, forming a spiral stirring from bottom to top, further increasing the stirring effect, and then because of the aggregation During the production and stirring process, styrene is a colloid and viscous substance. Therefore, when cleaning after stirring, it is convenient for the second batch of materials to enter. Traditionally, manual cleaning is required. If the stirring rod adds too many dead corners and is difficult to clean, the quality of polystyrene is affected, resulting in quality problems in the pretreatment of polystyrene. At this time, the active gear 206 is turned to drive the stirring member 7 on the stirring shaft 6 to rotate clockwise, so that the lower arc edge 701 is used to reversely scrape the inner wall of the insulating shell 1 so that the material on the inner wall of the insulating shell 1 is scraped clean, and then the stirring member 7 itself, when the motor 205 is turned over, starts the electromagnet 707 on multiple stirring members 7, so that each time a stirring member 7 is turned over, the stirring member 7 is turned over. When the stirring members 7 touch the inner wall of the heat-insulating shell 1, they will be adsorbed by the heat-insulating shell 1 to form a temporary storage groove 703 of the same size for scraping. Whenever they leave, the rebound of the spring 708 drives the angle between the electromagnet 707 and the elastic metal sheet 706 to become smaller. At the same time, the springs 708 on the multiple stirring members 7 make the rebound force smaller and smaller from top to bottom. This can be achieved by using springs of different lengths, so that the temporary storage groove 703 after rebound becomes larger and larger from top to bottom. At this time, when the stirring shaft 6 drives the stirring member 7 to rotate, the centrifugal force can be used to throw the material to the temporary storage groove 703, and then the stirring member 7 is set obliquely downward, so that it can be used while being thrown to the temporary storage groove 703;The centrifugal force continues to slide down until it is received by the temporary storage tank 703 of the next stirring element 7. This can facilitate the next receiving by making the previous temporary storage tank 703 smaller than the next temporary storage tank 703, and will not cause the material on the stirring element 7 to be thrown onto the opposite inner wall by the centrifugal force, so that the whole cleaning process is connected very smoothly and there will be no residue, and the cleaning is cleaner. ;
