Description

Technical Field

[0001] The utility model relates to the technical field of extruders, in particular to extrusion equipment for producing PCABS alloy. Background Art

[0002] PCABS alloy is also called engineering plastic alloy. This material has the excellent heat and weather resistance, dimensional stability and impact resistance of PC resin, and the excellent processing flowability of ABS resin. After searching, the Chinese patent authorization number CN218399342U discloses an extrusion device for the production of chemically resistant PCABS alloy. The device uses a baffle and a plurality of flow holes. The spacing between the baffle and the extrusion head and the diameter of the flow hole are smaller than the inner diameter of the extrusion tube, so that the impurities that will be stuck in the extrusion tube will be stuck before the baffle, so that the impurities inside the extrusion tube can be cleaned. The device filters the impurities through the baffle. After the baffle is used for a long time, the impurities will accumulate on one side of the baffle, but the space on one side of the baffle is small and cannot store too many impurities, thereby increasing the number of disassembly and cleaning. Utility Model Content

[0003] In view of the shortcomings of the prior art, the utility model provides an extrusion device for the production of PCABS alloy, which solves the problem that the existing device proposed in the background technology filters impurities through a baffle, and the impurities will accumulate on one side of the baffle after long-term use of the baffle, but the space on one side of the baffle is small and cannot store too many impurities, thereby increasing the number of disassembly and cleaning times.

[0004] To achieve the above purpose, the utility model is implemented through the following technical solutions: extrusion equipment for PCABS alloy production, including a device body, a filter tube, a first gear, a second gear and an extrusion port; a feed pipe is welded on the top of one end of the device body, and the bottom end of the feed pipe is connected to the inside of the filter tube, the filter tube is arranged inside the device body, and the outer wall of one end of the filter tube is welded to the device body, the first auger is located inside one end of the filter tube, the first auger is tightly fitted with the inner wall of the filter tube, and the first gear is mounted on the outside of one end of the first auger, the first gear is meshed with the second gear, and the second gear is mounted on the outside of the output end of the drive motor, the drive motor is installed on the outside of one end of the device body by screws, and the extrusion port is welded on the other end of the device body.

[0005] Preferably, the second gear is meshed with the third gear, and the third gear is mounted on the outside of one end of the second auger. The second auger is located at the bottom end inside the device body. When the second gear rotates, it can drive the third gear to rotate. The rotation of the third gear will drive the second auger to rotate, so that the second auger can transport the plastic alloy inside the device body and scrape and clean the inner wall of the device body.

[0006] Preferably, circular holes are evenly opened on the surface of the filter tube, and the top of one end of the filter tube is open, and a cover plate is arranged on the top of one end of the filter tube, and both ends of the cover plate are connected to the top of one end of the device body by screws. Impurities filtered inside the filter tube will gather at one end of the filter tube under the action of the first auger, and can then be cleaned by opening the cover plate.

[0007] Preferably, a rectangular hole is opened on one side of the device body, and a baffle is arranged outside the rectangular hole on one side of the device body. Both ends of the baffle are connected to the device body by screws. By removing the baffle, it is convenient to clean the inside of the device body through the hole on the side of the device body.

[0008] Preferably, the top of one end of the device body is in an arc-shaped protrusion, and there is a gap between the inner wall of the device body and the outer wall of the filter tube, which is conducive to allowing the plastic alloy inside the filter tube to enter the device body from all around the filter tube through the holes and grooves on the surface of the filter tube, thereby facilitating the improvement of fluidity.

[0009] Preferably, a top block is provided inside one end of the filter tube, the top block is welded to the pressure sensor, the pressure sensor is installed on the outside of the other end of the device body, and the pressure sensor and the device body are sealed, the pressure sensor is electrically connected to the indicator light, and the indicator light is located on both sides of the pressure sensor. When there are too many impurities inside one end of the filter tube, the impurities are continuously transported to one end of the filter tube under the drive of the first auger, so that the impurities at one end of the filter tube are continuously squeezed and compressed, and then the impurities will exert pressure on the top block, and the pressure on the top block is monitored by the pressure sensor. When the pressure is too high, the indicator light lights up, thereby reminding to clean the impurities inside the filter tube.

[0010] The utility model provides an extrusion device for producing PCABS alloy, which has the following beneficial effects:

[0011] (1) The extrusion equipment for producing PCABS alloy, when the device is in use, the heated and melted plastic alloy enters the interior of the filter tube through the feed port, and the second gear is driven to rotate by the driving motor. The second gear can drive the first gear to rotate while rotating, and then the first gear will drive the first auger to rotate. The plastic alloy in the feed tube can be transported to the interior of the filter tube through the first auger. After entering the interior of the filter tube, the plastic alloy will be filtered through the through holes on the surface of the filter tube, and impurities will remain in the filter tube. Driven by the first auger, the impurities in the filter tube will be pushed to one end of the filter tube for storage. The filtered plastic alloy enters the interior of the device through the through holes on the surface of the filter tube and is then extruded through the extrusion port. Under the scraping of the first auger, the impurities on the inner wall of the filter tube can be cleaned to avoid blocking the hole groove. The impurities are stored through the space at one end of the filter tube, which greatly increases the space for impurity storage, thereby reducing the number of disassembly and cleaning times.

[0012] (2) When there are too many impurities inside one end of the filter tube, the extrusion equipment for the production of PCABS alloy continuously transports the impurities to the one end of the filter tube under the drive of the first auger, so that the impurities at one end of the filter tube are continuously squeezed and compressed, and then the impurities exert pressure on the top block. The pressure on the top block is monitored by the pressure sensor. When the pressure is too high, the indicator light lights up, thereby reminding the user to clean the impurities inside the filter tube, which is conducive to improving the convenience of using the device, and then the inside of the filter tube can be cleaned by opening the cover.

[0013] This solves the problem that the existing device filters impurities through the baffle, and the impurities will accumulate on one side of the baffle after long-term use, but the space on one side of the baffle is small and cannot store too many impurities, thereby increasing the number of disassembly and cleaning times.
