Description

Technical Field

[0001] This utility model relates to the field of PVC plastic granule production technology, specifically a mixing device for PVC plastic granule production. Background Technology

[0002] In modern industrial production, PVC (polyvinyl chloride) plastic granules are widely used in building pipes, packaging materials, and electronic appliance housings due to their excellent chemical resistance, mechanical strength, and processing performance. As market demands for the quality of PVC plastic granules continue to increase, the mixing process becomes crucial, as the mixing effect directly affects the physical properties and molding quality of the granules.

[0003] According to patent document CN216831702U, a raw material mixing device for the production of ABS dyed plastic granules is disclosed. The device includes a supporting base frame, which is fixedly installed at the lower middle part of the outer wall of the mixing device body. A flow guiding mechanism is installed at the upper middle part of the inner wall of the mixing device body. A stirring mechanism is fixedly installed on the inner side of the mixing device body. A sealing block is installed at the middle of the bottom of the mixing device body via a closing mechanism. This invention can relatively conveniently and thoroughly mix the raw materials inside the mixing device body, avoiding the uneven mixing that often occurs with traditional devices. This improves the working efficiency of the device during use. Furthermore, the bottom of the mixing device body can be opened and closed relatively conveniently, effectively collecting the mixed raw materials inside the mixing device body, thus improving the practicality and convenience of the device during use.

[0004] Currently, most traditional PVC granule mixing equipment only has a single stirring and mixing function. In actual production, the materials to be mixed are prone to agglomeration and adhesion during storage and transportation due to moisture, electrostatic adsorption, or physical interactions between components. When these agglomerated material clumps enter the mixing equipment, they are not only difficult to disperse evenly, but also lead to prolonged mixing time, increased energy consumption, and even local over- or under-mixing, which seriously affects the quality stability of PVC granules.

The output end of the second motor 308 is fixedly connected to a crushing roller 309, and the bottom of the inner wall of the material box 304 is fixedly connected to a sieve plate 310. By setting a pre-treatment mechanism 3, the material to be pre-treated is poured into the inner cavity of the material box 304. Then, the second motor 308 is started by the external PLC controller. The second motor 308 drives the crushing roller 309 to rotate, thereby crushing the agglomerated material. After the material is smaller than the aperture of the sieve plate 310, the material will fall into the inner cavity of the housing 1. At the same time, the first motor 201 is started. When the first motor 201 is working, it will cause the connecting shaft 301 to rotate. The connecting shaft 301 drives the synchronous pulley 302 to rotate, and the synchronous pulley 302 drives the synchronous belt 303 to rotate, thereby driving the fixed rod 307 to rotate.

By setting the bearing and the connecting seat, the operation of the connecting shaft 301 is stabilized and displacement of the connecting shaft 301 is prevented. A vertical rod is fixedly connected to the bottom of the shell 1, and a hollow rod 311 is fixedly connected to one side of the vertical rod. The rear side of the inner cavity of the hollow rod 311 is provided with a drive sprocket 312. The inner cavity of the drive sprocket 312 is fixedly connected to the second stirring roller 204. A chain 313 is meshed on the surface of the sprocket 312, and a driven sprocket 314 is meshed on the front side of the inner surface of the chain 313.

[0025] Working principle: By setting up a pre-treatment mechanism 3, the material to be pre-treated is poured into the inner cavity of the material box 304. Then, the second motor 308 is started by the external PLC controller. The second motor 308 drives the crushing roller 309 to rotate, thereby crushing the agglomerated material. After the material is smaller than the aperture of the sieve plate 310, the material will fall into the inner cavity of the shell 1. At the same time, the first motor 201 is started. When the first motor 201 is working, it will cause the connecting shaft 301 to rotate. The connecting shaft 301 drives the synchronous wheel 302 to rotate. The synchronous wheel 302 drives the synchronous belt 303 to rotate, thereby driving the fixed rod 307 to rotate. The fixed rod 307 drives the connecting plate 306 to move. The connecting plate 306 drives the telescopic rod 305 to move. The telescopic rod 305 drives the material box 304 to move back and forth, thereby making the material fall evenly into the inner cavity of the shell 1, thus improving the mixing efficiency.

[0026] By setting up the stirring mechanism 2, the first motor 201 is started to work. The first motor 201 will drive the first stirring roller 203 to rotate. At the same time, through the cooperation of the pulley 205 and the belt 206, the second stirring roller 204 can be easily driven to rotate, which can stir the material and facilitate the mixing of the material.
