Description

Technical Field

[0001] This utility model relates to the field of plastic processing technology, specifically to a molding device for plastic processing. Background Technology

[0002] In the plastics processing industry, converting plastic raw materials into moldable granules suitable for manufacturing various products is a crucial step. This typically requires a series of complex and precise processing steps using molding equipment, encompassing extrusion molding, cooling and setting, dehydration and drying, and pelletizing. Regarding cooling and setting, some equipment uses water cooling, which leaves a significant amount of moisture on the material. Currently, drying is often achieved by blowing air through fans. This method removes moisture through airflow, requiring specific pre-drying structures. However, when there is a high level of moisture on the outer surface of the material, the drying effect is poor, leading to uneven drying and impacting the quality of the final product, especially when precise moisture content control is required. Utility Model Content

[0003] The purpose of this invention is to provide a molding apparatus for plastic processing to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a molding apparatus for plastic processing, comprising...

[0005] Extruder;

[0006] A cold water tank is placed at the discharge end of the extruder;

[0007] A dewatering tank is located at the end of the cold water tank. The dewatering tank has two suction pipes installed inside, one above the other. The top of the suction pipe has a slot, and both sides of the slot are fixed with limit baffles. A roller filter screen is installed on the outer side of the suction pipe and is slidably connected to the limit baffles. This is used to perform negative pressure dewatering while pulling and conveying materials.

[0008] The pelletizer is fixed to one end of the dewatering tank.

[0009] Preferably, one end of the drum filter screen is rotatably connected to the dewatering tank, and gears are fixedly connected to the ends of the drum filter screen. The upper and lower gears are meshed together, and a motor that drives one of the gears is fixedly connected to the bottom of the dewatering tank.

[0010] Preferably, the water suction pipe is fixed to one side of the water removal tank, and one end of the water suction pipe is fixed to a bend connector.

[0011] Preferably, one end of the bent pipe joint is fixedly connected to a filter box, and a vortex air pump that draws the inside of the filter box into negative pressure is installed on the outside of the filter box.

[0012] Preferably, a heating box is fixed to the outside of the water tank, an electric heating wire is installed inside the heating box, and a fan for blowing air into the heating box is installed on one side of the heating box.

[0013] Preferably, a metal pipe is fixed to the top of the heating box, and an air outlet hood is installed at the end of the metal pipe.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: Two suction pipes are symmetrically arranged vertically inside the dewatering tank. The top of each suction pipe has a slot and two limit baffles on both sides. A rubber plate is installed on the top of the limit baffles and slidably connected to the outside of the drum filter screen. When the drum filter screen rotates, a vortex air pump draws negative pressure inside the suction pipe. Under the protection of the limit baffles, the drum filter screen and the slot of the suction pipe have negative pressure, which can effectively adsorb moisture from the outside of the material while conveying it, thus improving the dewatering efficiency. One end of the drum filter screen is rotatably connected to the dewatering tank, and a gear is fixedly connected to the other end. Furthermore, the upper and lower gears are meshed and connected. The motor at the bottom of the water tank drives one of the gears, which in turn drives the two gears to rotate via a transmission belt and pulley. This, in turn, drives the two roller filter screens to rotate, thus conveying and pulling the material forward. Water on the outside of the roller filter screens enters the suction pipe through the through holes, and then enters the filter box through the bent pipe joint. Inside the filter box, the water absorption net is arranged from the inside out as a stainless steel mesh, a layer of super absorbent resin particles, and another stainless steel mesh. This can fully remove water from the passing air, prevent water from re-entering the system, and ensure the negative pressure water removal effect. Attached Figure Description

The formed material enters the cold water tank 2 for water cooling and shaping. After shaping, it passes through two roller filters 15. During the rolling of the upper and lower roller filters 15, the strip-shaped material is conveyed to one end. At the same time, the vortex air pump 11 draws negative pressure into the suction pipe 16. Under the protection of the limiting baffle 17, the suction pipe 16 has negative pressure at the opening of the roller filters 15 and the suction pipe 16, thereby adsorbing and removing water from the outside of the material during the conveying process. Then, it enters the pelletizer for cutting.

[0026] In one embodiment, the suction pipe 16 is fixed to one side of the dewatering tank 3, and one end of the suction pipe 16 is fixed to a bend joint 12. One end of the bend joint 12 is fixed to a filter box 10. A vortex air pump 11 is installed on the outside of the filter box 10 to draw the inside of the filter box 10 into negative pressure.

[0027] It should be noted that in this embodiment, the vortex air pump generates negative pressure to extract the gas inside the filter box, thereby creating a negative pressure environment inside the filter box. Under the connection between the elbow joint 12 and the water suction pipe 16, the groove of the water suction pipe 16 is under negative pressure, so that the water on the outside of the roller filter screen 15 enters the water suction pipe 16 through the through hole and then enters the filter box 10 through the elbow joint 12. The filter box 10 is equipped with a water suction net, which is arranged from the inside to the outside as a stainless steel mesh, a super absorbent resin particle filling layer, and a stainless steel mesh, thereby removing water from the air passing through the filter box 10.
