Description

Technical Field

[0001] The utility model relates to the technical field of polyvinyl chloride resin processing, in particular to an anti-clogging polyvinyl chloride resin stirring device. Background Art

[0002] Polyvinyl chloride resin is one of the five general-purpose plastics and is widely used in industry, agriculture, construction and other fields. During the production process of polyvinyl chloride resin, a mixing barrel is required to continuously stir the polyvinyl chloride resin raw materials and add corresponding additives so that the final polyvinyl chloride resin product obtains the desired properties.

[0003] PVC resin is in a fluid form with high viscosity. Therefore, residues will appear near the discharge port during the mixing and discharging process. As the equipment is used multiple times, the residual PVC resin near the discharge port accumulates more and more, gradually causing the discharge port to be blocked. Therefore, it is necessary to manually clean the discharge port of the mixing equipment regularly. However, the PVC resin has solidified at this time, making it difficult to clean and requiring a large amount of labor.

[0004] Therefore, in order to address the problem that during the above-mentioned polyvinyl chloride resin mixing process, there is material residue near the discharge port of the equipment for a long time, which easily causes the discharge port to be blocked and is difficult to clean manually, a polyvinyl chloride resin mixing device that can automatically clean the discharge port can be designed to eliminate manual cleaning and ensure the normal operation of the equipment. Utility Model Content

[0005] In order to overcome the problem that there is material residue near the discharge port of the polyvinyl chloride resin mixing equipment for a long time, which easily causes the discharge port to be blocked and makes manual cleaning difficult.

[0007] Preferably, the melting temperature of the polyvinyl chloride resin is 170°C-190°C, and the high-temperature resistant silicone material used in the mouth-opener is a special silicone with a high-temperature resistance coefficient of 260°C-320°C, and its high-temperature resistance can be further improved by changing the composition of the silicone material, so that when it dredges the discharge port, it first crushes and lifts the solidified polyvinyl chloride resin blocking the inner wall of the discharge port and drops it at the junction of the bottom wall of the stirring tank and the discharge port. After entering the expansion cavity, the mouth-opener is deformed by the reverse pressure of the expansion cavity, and a gap is left between the bottom and the discharge port. While the broken polyvinyl chloride resin slides out through the gap, the mouth-opener is heated by the heating rod and has high temperature. When it is pulled back, it acts on the polyvinyl chloride resin remaining at the junction of the bottom wall of the stirring tank and the discharge port, causing this part of the polyvinyl chloride resin to melt. During the continuous pulling back of the mouth-opener, the polyvinyl chloride resin melted by the high temperature is scraped and removed from the discharge port.

[0008] Preferably, the stirring mechanism includes a driving motor and a central axis column; a bracket is fixedly installed on the inner wall of the feed port, the driving motor is installed at the upper end of the bracket, and the lower end of the transmission shaft of the driving motor is installed with a central axis column extending into the stirring tank, the expansion cavity is fixedly connected to the lower end of the central axis column, the central axis column is a hollow structure connected to the expansion cavity, the power supply module of the heating rod is arranged in the cavity of the central axis column, the heating module of the heating rod is in the expansion cavity, the driving motor controls the central axis column to rotate in clockwise and counterclockwise directions, and the rotation cycle is 1-2 minutes, and a sealing structure is arranged between the heating module of the heating rod and the cavity of the central axis column to prevent molten polyvinyl chloride resin from entering the cavity.

[0009] Preferably, the stirring mechanism further comprises an edge stirring frame, an upper stirring frame, a lower stirring frame, and a bottom mixer; the edge stirring frame has eight groups, and the edge stirring frame is composed of an outer oblique straight portion, a vertical portion, and an inner oblique straight portion distributed from bottom to top, and the outer oblique straight portion, the vertical portion, and the inner oblique straight portion are all rod-shaped structures that fit the line of the inner wall of the stirring tank, the lower end of the outer oblique straight portion is fixedly connected to the outer wall of the expansion cavity, the outer wall of the vertical portion is fixedly connected to a Y-shaped upper stirring frame on the side facing the central axis column, the Y-shaped intersection of the upper stirring frame is parallel to the central axis column, the lower stirring frame below the upper stirring frame is fixedly connected between the outer wall of the vertical portion and the outer oblique straight portion, and the vertical portion is fixedly connected to the outer wall of the vertical portion. A pentagonal cavity is formed between the straight portion, the outer oblique straight portion and the lower stirring frame, and the bottom mixer is arranged in the pentagonal cavity. In practical applications, the upper stirring frame can use a Y-shaped structure as in the present technical solution, or an oblique cross-shaped structure, etc., both of which can have a deep stirring effect on the resin particles that have not been completely melted in the upper layer of the stirring tank. The pentagonal cavity formed by the vertical portion, the outer oblique straight portion and the lower stirring frame can also be designed as a circular or rectangular structure in practical applications, aiming to provide an obstacle-free space for the operation of the bottom mixer, while having a stirring effect on the molten resin materials in the middle and lower layers.

[0010] Preferably, the bottom mixer is composed of a motor and a mixing roller. The motor is installed on the vertical part. A plurality of prying rods are fixedly connected to the outer wall of the mixing roller. One end of the mixing roller is fixedly connected to the drive shaft of the motor and is driven by the motor to stir the polyvinyl chloride resin material in the pentagonal cavity. The bottom mixer fully stirs the molten resin material passing through the pentagonal cavity by rotating the mixing roller arranged obliquely downward at high speed, thereby strengthening the contact area between the resin material and the lower stirring frame, and greatly enhancing the stirring impact effect.

[0011] Preferably, the flipping and positioning mechanism includes a swivel arm, a bracket, and a steering motor; two swivel arms are symmetrically arranged on the left and right, and the upper ends are movably connected to the pallet through a rotating shaft, a bracket is fixedly connected between the lower ends of the swivel arms, a steering motor is installed on one side of the pallet, the rotating shaft of the swivel arm is fixedly connected to the drive shaft of the steering motor, and the steering motor drives the swivel arm and the bracket to flip at an angle of ninety degrees.
