Description

Technical Field

[0001] The utility model relates to the technical field of PVC heat stabilizer production equipment, in particular to a stirring device for PVC heat stabilizer. Background Art

[0002] Polyvinyl chloride (PVC) is widely used in building materials, industrial products, daily necessities, floor coverings, floor tiles, artificial leather, pipes, wires and cables, packaging films, bottles, foaming materials, sealing materials, fibers, etc. However, it has poor stability to light and heat. At temperatures above 100°C or after prolonged exposure to sunlight, it will decompose to produce hydrogen chloride, which is harmful to human health. It will further autocatalytically decompose, causing discoloration and a rapid decline in physical and mechanical properties. Therefore, heat stabilizers are essential additives in the PVC plastic molding process.

[0003] A stirring device for PVC heat stabilizer is disclosed in the Chinese utility model patent application with the specification CN213032360U. Although the sliding sleeve can move up and down in the sliding cavity by controlling the hydraulic rod, the stirring shaft can also move up and down to stir more fully while stirring, which not only can make the powder heat stabilizer and the solution uniform and fully mixed with equal concentration, but also is very simple to operate, saving time and effort and improving efficiency. However, the stock solution precipitated at the bottom of the equipment cannot be fully stirred during the stirring process, resulting in more raw materials remaining at the bottom of the equipment, resulting in unnecessary waste. Therefore, a stirring device for PVC heat stabilizer is proposed. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] By starting the motor, the rotating rod is driven to rotate, thereby driving the stirring rod and the cleaning plate to rotate synchronously. At this time, under the action of the stirring rod, the auxiliary rod and the cleaning plate, the solid salt raw materials and the liquid inside the machine body can be effectively stirred. At the same time, the cleaning plate contacts the bottom end of the machine body, and the liquid stirred at the bottom end of the machine body can be effectively pushed upward along the inclined surface of the cleaning plate surface, so that the solid salt raw materials and liquid inside the machine body will not settle at the bottom end of the machine body, but will continuously and repeatedly move up and down inside the machine body, so as to achieve a fully uniform stirring effect.

[0014] By placing the material receiving box on the carrying plate and placing the positioning block into the positioning groove, and then pushing it inward, when the positioning block contacts the pressure rod, it will move along the inclined surface of the pressure rod, and the pressure rod can be easily moved upward. At this time, when the positioning block contacts the bottom end of the positioning groove, the pressure rod moves downward under the action of the counterweight block, and is stuck in the through groove inside the positioning block, forming a positioning effect for the material receiving box. This setting can keep the placement position of the material receiving box consistent each time and is below the discharge port, so that the mixed raw materials can all fall into the material receiving box. At the same time, this operation is relatively simple and quick. After the material receiving is completed, you only need to lift the pull rod upward to cancel the positioning effect of the material receiving box, which is convenient for removing the material receiving box, thereby improving the overall practical effect of the equipment.
