Description

Technical Field

[0001] The utility model relates to the technical field of plastic processing, in particular to a high-performance PVC plastic mixer. Background Art

[0002] PVC was once the world's most produced general-purpose plastic and is widely used. There are two types of PVC: hard and soft. Hard polyvinyl chloride is used for building pipes, doors and windows. It is also used to make plastic bottles, packaging, bank cards or membership cards. Adding plasticizers can make PVC softer and more flexible. It can be used for pipes, cable insulation, flooring, signs, phonograph records, inflatable products and rubber substitutes. PVC has poor fluidity, low impact strength, poor weather resistance, and is prone to high temperature degradation during processing. Therefore, heat stabilizers, lubricants and other modifying additives are added during the manufacturing process of PVC to improve the processing properties and usage properties of PVC.

[0003] The patent with the authorization announcement number CN212498471U discloses a dry mixer for producing PVC plastics, which relates to the field of plastic processing, including a shell, in which a lower baffle is fixedly provided, and the lower baffle divides the interior of the shell into a left chamber and a right chamber. The utility model separates drying and stirring to form two stirrings, thereby increasing the homogenization degree of the material; there are multiple agitators and they are arranged in a staggered manner, which increases the stirring time of the material in the shell, so that the materials put in front and behind are contacted and mixed, and prevents the situation where the materials are staggered in drying and stirring. In the process of mixing PVC and modifying additives in the above patent, the process is too complicated, especially in the first process, the raw materials and modifying additives need to be dried and mixed in reverse from top to bottom, the required wind force is large and the effect is limited, and in the early stage when the raw materials and modifying additives are not dried, the raw materials and modifying additives are prone to block the air outlet, resulting in processing stagnation, and there are certain safety risks. At the same time, the processing energy consumption is large, which is not suitable for large-scale plastic processing. Summary of the invention

The height of the outlet 13 is the same as that of the air inlet 15. The front and rear sides above the mixing cylinder 1 are fixedly inserted and installed with a first feed pipe 5 and a second feed pipe 6 respectively. Symmetrically distributed fixing seats 2 are fixedly installed at the bottom of the mixing cylinder 1. A motor 3 is fixedly installed at the central position on the left side of the first baffle 11. The output end of the motor 3 penetrates through the first baffle 11 and is fixedly connected to one end of the central rod 7. During use, PVC materials and modification additives are added into the mixing cylinder 1 through the first feed pipe 5 and the second feed pipe 6 respectively. The external power supply is connected, and the motor 3 and the hot air blower 4 are started. The hot air blower 4 blows hot air into the mixing cylinder 1 through the air inlet 15. The motor 3 drives the central rod 7 and the mixing mechanism to rotate, stirring and mixing the PVC materials and the modification additives. In this way, the mixing and drying of the PVC materials and the modification additives can be carried out synchronously. At the same time, as the PVC materials and the modification additives are dried during mixing, the air blown into the mixing cylinder 1 by the hot air blower 4 can blow and blow out the mixture from the mixing cylinder 1. The thoroughly dried mixture is blown out through the outlet 13, realizing the collection of the dried mixture.

The thoroughly dried mixed material is blown out through the discharge port 13 to realize the collection of the dried mixed material. In this way, the mixing, drying and collection of the PVC material and the modification additive can be completed simultaneously in the mixing cylinder 1, thus realizing the efficient processing of PVC, greatly reducing energy consumption at the same time, and there will be no phenomenon of material blockage; The central rod 7 drives the first mixing plate 71 and the second mixing plate 72 to rotate to stir and mix the PVC material and the modification additive.
