Description

Technical Field

[0001] This utility model belongs to the field of cooling equipment, and specifically relates to an extrusion cooling device for PPS composite material production. Background Technology

[0002] Extrusion cooling units for PPS composite material production are key equipment in the process of producing polyphenylene sulfide (PPS) composite materials. Their main function is to rapidly and effectively cool the high-temperature PPS composite material extruded from the extruder to ensure product quality and performance. Current PPS composite material extrusion cooling units have certain drawbacks, mostly relying on common single water cooling or single air cooling systems. This single structure stems primarily from limitations of traditional design thinking and cost control considerations. Early research and development and production processes did not fully consider the complex thermophysical properties of PPS composite materials and the diverse production process requirements. When the cooling structure is singular, uneven cooling is prone to occur because different parts of the PPS composite material have varying degrees of contact with the cooling medium during extrusion, potentially leading to uneven internal stress distribution, deformation, and other quality problems. Conventional methods to address this include optimizing the flow rate and temperature control of the cooling medium, such as more precisely adjusting the water flow rate for water cooling or the air velocity for air cooling. However, this method has a limited adjustable range and cannot completely overcome the problem of uneven cooling. Therefore, a new structure is needed to solve the aforementioned technical problems. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an extrusion cooling device for PPS composite material production, so as to solve the problems mentioned in the background technology.

[0004] This utility model is achieved through the following technical solution: a PPS composite material production extrusion cooling device, comprising: an extrusion assembly and a cooling assembly, wherein the outlet of the extrusion assembly is equipped with a cooling assembly for cooling the PPS composite material, the extrusion assembly comprises: a base plate, a transmission component and an extruder, the extruder is mounted on the upper surface of the base plate via the transmission component, an extrusion tube is installed inside the extruder, a feed hopper is mounted on the upper side of the outer surface of the extruder, an auger is mounted inside the extrusion tube via the transmission component, the cooling assembly comprises: a cooling shell, a water-cooled pipe and an air-cooled pipe, the cooling shell is mounted on the outer surface of the extruder, the water-cooled pipe and the air-cooled pipe are installed through the outer surface of the cooling shell, and a collecting plate is mounted on the lower surface of the cooling shell.

[0005] In a preferred embodiment, the base plate has an L-shaped structure. A base one and a base two are mounted on the upper surface of the base plate. A transmission component is mounted in front of the base one through the base plate. An extruder is mounted on the upper surface of the base two. The extruder includes a protective shell, an extrusion tube, and a feed hopper.

[0006] In a preferred embodiment, an extrusion tube is installed on the upper surface of the second base through a protective shell. An auger is rotatably installed inside the extrusion tube via a transmission component. A discharge port is provided at the end of the extrusion tube away from the first base. A feed hopper is installed on the upper surface of the protective shell, and the feed hopper is connected to the inside of the extrusion tube. In use, since the cooling component is directly installed at the discharge port of the extrusion component, the transmission distance of the PPS composite material from extrusion to entering the cooling stage is extremely short, greatly reducing the possibility of the material being disturbed by external factors during transmission.

[0007] In a preferred embodiment, a cooling shell is installed on one side surface of the protective shell with a discharge port. The cross-sectional section of the cooling shell matches the cross-sectional section of the protective shell. A collection plate with a semi-arc structure is installed on the lower surface of the protective shell. A drain valve is installed on the lower surface of the collection plate. A filter screen is provided at the connection between the collection plate and the cooling shell.

[0008] In a preferred embodiment, a water-cooling pipe is symmetrically installed through the left and right edges of the upper surface of the cooling shell. The end of the water-cooling pipe away from the cooling shell is connected to a water supply device. An air-cooling pipe is symmetrically installed on the left and right surfaces of the cooling shell. In use, the water-cooling pipe and the air-cooling pipe are installed through the outer surface of the cooling shell, which can cool the extruded part and the PPS composite material inside it from all directions. This multi-dimensional cooling method can ensure that the material is cooled uniformly in all directions.

[0009] In a preferred embodiment, the air-cooled pipe is designed with an inner higher and outer lower slope at a 25-degree angle. The end of the air-cooled pipe away from the cooling shell is connected to the cooling distribution equipment. The air outlet end of the air-cooled pipe and the water outlet end of the water-cooled pipe are both collinear with the central axis of the discharge port.

[0010] After adopting the above technical solution, the beneficial effects of this utility model are as follows: By setting an extrusion assembly, a cooling assembly for cooling PPS composite material is installed at the discharge port of the extrusion assembly. The extrusion assembly includes a base plate, a transmission component, and an extruder. During use, since the cooling assembly is directly installed at the discharge port of the extrusion assembly, the transmission distance of the PPS composite material from extrusion to entering the cooling stage is extremely short, which greatly reduces the possibility of the material being disturbed by external factors during transmission. For example, it avoids problems such as uneven temperature drop of the material, contamination, or shape change due to gravity caused by excessive transmission distance. This ensures that the state of the material is relatively stable when it enters the cooling assembly, which is beneficial to the uniformity and stability of the subsequent cooling process, thereby improving the consistency of product quality.

[0011] By setting up a cooling assembly, which includes a cooling shell, water-cooled pipes, and air-cooled pipes, the cooling shell is installed on the outer surface of the extruder. The water-cooled pipes and air-cooled pipes are installed through the outer surface of the cooling shell. A collection plate is installed on the lower surface of the cooling shell. During use, the water-cooled pipes and air-cooled pipes are installed through the outer surface of the cooling shell, which can cool the extruder and its internal PPS composite material in all directions. This multi-dimensional cooling method can ensure that the material is cooled evenly in all directions, avoiding problems such as product deformation and internal stress concentration caused by local overheating or uneven cooling, thereby improving the quality and performance stability of the product.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1 to 3 This utility model provides a technical solution: a PPS composite material production extrusion cooling device, including: an extrusion assembly and a cooling assembly. The outlet of the extrusion assembly is equipped with a cooling assembly for cooling the PPS composite material. The extrusion assembly includes: a base plate 100, a transmission component 110 and an extruder. The extruder is installed on the upper surface of the base plate 100 through the transmission component 110. An extrusion tube 150 is installed inside the extruder. A feed hopper 140 is installed on the upper side of the outer surface of the extruder. An auger is installed inside the extrusion tube 150 through the transmission component 110. The cooling assembly includes: a cooling shell 200, a water-cooled pipe 210 and an air-cooled pipe 220. The cooling shell 200 is installed on the outer surface of the extruder. The water-cooled pipe 210 and the air-cooled pipe 220 are installed through the outer surface of the cooling shell 200. A collection plate 240 is installed on the lower surface of the cooling shell 200.

[0020] Please see Figures 1 to 3 As the first embodiment of this utility model: the base plate 100 has an L-shaped structure, and a base 120 and a base 2 are installed on the upper surface of the base plate 100. A transmission component 110 is installed in front of the base 120 through the base plate 100. An extruder is installed on the upper surface of the base 2. The extruder includes: a protective shell 130, an extrusion tube 150, and a feed hopper 140.

[0021] An extrusion tube 150 is installed on the upper surface of the base 2 through the protective shell 130. An auger is rotatably installed inside the extrusion tube 150 through the transmission component 110. A discharge port is provided at the end of the extrusion tube 150 away from the base 1 120. A feed chamber 140 is installed on the upper surface of the protective shell 130. The feed chamber 140 is connected to the inside of the extrusion tube 150.

[0022] When using the product, the user first melts the PPS composite material using external equipment and discharges it into the extrusion tube 150 through the feed hopper 140. While the PPS composite material is being discharged through the feed hopper 140, the user can activate the transmission component 110, which drives the auger inside the extrusion tube 150, causing it to rotate (the opening diameter at the outlet of the extrusion tube 150 gradually decreases). After the extruder extrudes the PPS composite material, the user can cool and shape it using the cooling component. Because the cooling component is directly installed at the outlet of the extrusion component, the transmission distance of the PPS composite material from extrusion to the cooling stage is extremely short, greatly reducing the possibility of external interference during transmission. This avoids problems such as uneven temperature drop, contamination, or shape changes due to gravity caused by excessive transmission distance, ensuring a relatively stable state of the material upon entering the cooling component. This is beneficial for the uniformity and stability of the subsequent cooling process, thereby improving the consistency of product quality.

[0023] Please see Figures 1 to 3 As a second embodiment of the present invention: a cooling shell 200 is installed on one side surface of the protective shell 130 with a discharge port. The cross section of the cooling shell 200 matches the cross section of the protective shell 130. A collection plate 240 with a semi-arc structure is installed on the lower surface of the protective shell 130. A drain valve is installed on the lower surface of the collection plate 240. A filter screen 230 is provided at the connection between the collection plate 240 and the cooling shell 200.

[0024] A water-cooling pipe 210 is symmetrically installed through the left and right edges of the upper surface of the cooling housing 200. The end of the water-cooling pipe 210 away from the cooling housing 200 is connected to the water supply equipment. An air-cooling pipe 220 is symmetrically installed on the left and right surfaces of the cooling housing 200.

[0025] The air-cooled pipe 220 is designed with an inner high and outer low slope at 25 degrees. The end of the air-cooled pipe 220 away from the cooling shell 200 is connected to the cooling sub-equipment. The air outlet end of the air-cooled pipe 220 and the water outlet end of the water-cooled pipe 210 are both collinear with the central axis of the discharge port.

[0026] During use, after the PPS composite material is extruded through the outlet end of the extrusion pipe 150, the user can activate the external water supply and cooling equipment (both of which are existing technologies, and their structures and principles will not be elaborated here). The water supply and cooling equipment will then spray cold water and cold air onto the extruded PPS composite material through the water-cooling pipe 210 and the cold air pipe, respectively. The PPS composite material will then be rapidly cooled by the cold water and cold air. The sprayed water will fall through the filter screen 230 into the collection plate 240 and then be discharged through the drain valve on the lower surface of the collection plate 240 for recycling. Because the water-cooling pipe 210 and the air-cooling pipe 220 are installed through the outer surface of the cooling shell 200, they can provide all-around cooling for the extruded part and the PPS composite material inside. This multi-dimensional cooling method ensures that the material is cooled uniformly in all directions, avoiding problems such as product deformation and internal stress concentration caused by localized overheating or uneven cooling, thereby improving product quality and performance stability. (In actual use, the protective shell 130 is at a certain distance from the outlet end to avoid the cooling effect of the cooling components directly affecting the outlet. Instead, the outlet is cooled after a certain length of material has been discharged.)

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
