Description

Technical Field

[0001] This utility model relates to the technical field of extrusion devices, specifically an extrusion device for the production of cable protection pipes. Background Technology

[0002] The extrusion device used in cable protection pipe production is a key piece of equipment in the manufacturing of cable sheathing pipes. It is responsible for uniformly and continuously extruding the raw material to form the required cable protection pipe. The working principle of the extrusion device is mainly based on the single-screw extrusion principle. Driven by a motor, the screw rotates and squeezes the raw material inside the sheath, causing it to move forward and be ejected through the nozzle. Due to the rotation and squeezing action of the screw, the raw material is subjected to shearing and frictional forces during the flow process, thereby achieving its plasticization and melting. Finally, the molten raw material is ejected through the nozzle to form the required cable protection pipe.

[0003] The extrusion equipment used in the production of existing cable protection pipes mostly uses granular raw materials. During the storage process, the raw materials may be mixed with impurities or dust due to poor storage environment. The presence of impurities or dust may cause defects on the product surface, reduce the strength and toughness of the product, and even affect the service life of the product. Utility Model Content

[0004] The purpose of this utility model is to provide an extrusion device for the production of cable protection pipes, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An extrusion device for producing cable protection pipes includes a main body, a screw extrusion mechanism on the main body, a feeding hopper on the screw extrusion mechanism, and a purification mechanism on the main body for purifying the raw materials used by the extrusion mechanism.

[0007] Preferably, a conveying screw is rotatably installed inside the feeding hopper, and a motor is fixedly installed on the top of the feeding hopper, with the output end of the motor being fixedly connected to one end of the conveying screw.

[0008] Preferably, an inclined plate is provided below the feed hopper inside the shell, and a material dispersing component is fixedly provided on the inclined plate.

[0009] Preferably, an outer shell is fixedly installed inside the housing, a dust suction end is fixedly installed outside the outer shell, a dust suction box is fixedly installed inside the outer shell, a filter cartridge is fixedly installed inside the dust suction box, a dust suction pipe is installed on the dust suction box, and one end of the dust suction pipe extends into the interior of the dust suction end. A dust suction fan is fixedly installed inside the housing, and the air inlet of the dust suction fan extends into the interior of the dust suction box. An air duct is connected to the air outlet of the dust suction fan, and one end of the air duct extends into the exterior of the housing.

[0010] Preferably, the housing is provided with a storage box inside, and the storage box is located below one side of the inclined plate.

[0011] Preferably, the shell has a cylindrical body inside, and the inlet of the cylindrical body is connected to the outlet of the storage box.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model features a housing. Raw materials enter the housing through a feeding hopper and slide down an inclined plate onto a material dispersing component. The material dispersing component disperses the raw materials, ensuring they fall evenly under gravity. A dust collector starts, generating suction to capture dust and small impurities from the raw materials as they fall evenly. These impurities are then drawn into a dust collection box. Inside the dust collection box, the dust and impurities are filtered by a filter cartridge. Clean air is discharged through the filter cartridge and the exhaust end of the dust collector, exiting the housing through a duct. The dispersed and purified raw materials fall into a storage bin. From the storage bin, the raw materials enter the cylinder's inlet through its outlet. A second motor starts, driving the auger conveyor shaft to rotate, transporting the raw materials inside the cylinder. The transported raw materials then enter the discharge pipe from the cylinder's outlet and are finally delivered to the feeding hopper for use by the screw extrusion mechanism. This process removes impurities and dust from the raw materials, improving their purity and ultimately enhancing the quality and performance of the product. Attached Figure Description

[0019] 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.

[0020] Please see Figures 1-4An extrusion device for producing cable protection pipes includes a main body 1, a screw extrusion mechanism 2 mounted on the main body 1, a feeding hopper 3 mounted on the screw extrusion mechanism 2, a conveying screw 4 rotatably mounted inside the feeding hopper 3, a motor 5 fixedly mounted on the top of the feeding hopper 3, and the output end of the motor 5 fixedly connected to one end of the conveying screw 4. The main body 1 is also equipped with a purification mechanism for purifying the raw materials used in the extrusion mechanism. The purification mechanism is a housing 6, on which a feed hopper 7 and a discharge pipe 8 are respectively mounted. One end of 8 extends into the interior of the feeding hopper 3. The main body 1 is the basic structure of the entire extrusion device, bearing all functional components and ensuring their coordinated operation. The screw extrusion mechanism 2 is the core part of the device, extruding the raw material into the required shape and size through the rotation of the screw. The feeding hopper 3 is located above the screw extrusion mechanism 2 and is used to store and feed the raw material. The conveying screw 4 is located inside the feeding hopper 3 and feeds the raw material evenly into the screw extrusion mechanism 2 through rotation. The motor 5 provides power to the conveying screw 4, ensuring its continuous and stable operation. During the installation of housing 6, raw materials enter the housing 6 through the feed hopper 7 and slide down the inclined plate 9 onto the material dispersing component 10. The material dispersing component 10 disperses the raw materials, ensuring that they fall evenly downwards under gravity. The dust collector 16 is activated, generating suction. The dust collector 15 and the dust collector 14 capture dust and small impurities contained in the raw materials during their even descent and suck them into the dust collection box 12. The dust and impurities are filtered by the filter cartridge 13 in the dust collection box 12. Clean air passes through the filter cartridge 13 and the exhaust air from the dust collector 16. The raw material is discharged from the end and exits the shell 6 through the air duct 17. After dispersion and purification, the raw material falls into the storage box 18. The raw material in the storage box 18 enters the feed port of the cylinder 19 through its discharge port. The motor 21 starts and drives the auger conveyor shaft 20 to rotate, conveying the raw material inside the cylinder 19. The conveyed raw material enters the discharge pipe 8 from the discharge port of the cylinder 19 and is finally conveyed to the feeding hopper 3 for use by the screw extrusion mechanism 2, thereby removing impurities and dust from the raw material, improving the purity of the raw material, and thus improving the quality and performance of the product.

[0021] Please see Figure 3 and Figure 4An inclined plate 9 is installed below the feed hopper 7 inside the housing 6. A material dispersing component 10 is fixedly installed on the inclined plate 9. An outer shell 11 is fixedly installed inside the housing 6. A dust suction end 15 is fixedly installed on the outside of the outer shell 11. A dust suction box 12 is fixedly installed inside the outer shell 11. A filter cartridge 13 is fixedly installed inside the dust suction box 12. A dust suction pipe 14 is installed on the dust suction box 12, and one end of the dust suction pipe 14 extends into the inside of the dust suction end 15. A dust suction fan 16 is fixedly installed inside the housing 6, and the air inlet of the dust suction fan 16 extends into the inside of the dust suction box 12. An air duct 17 is connected to the air outlet of the dust suction fan 16, and one end of the air duct 17 extends into the outside of the housing 6. The feed hopper 7 is located on the upper part of the purification mechanism. The feed hopper 7 is used to feed the raw materials to be purified. The discharge pipe 8 transports the purified raw materials into the feed hopper 3 for use by the screw extrusion mechanism 2. The inclined plate 9 is located below the feed hopper 7 and is inclined so that the raw materials fed into the feed hopper 7 can slide down through the inclined plate 9. The material dispersing component 10 is fixed on the inclined plate 9 to disperse the sliding raw materials, ensuring that the raw materials can fall evenly downwards under gravity. The outer shell 11 is fixed inside the housing 6, providing a closed installation space for the dust collection system. The dust collection end 15 is located outside the outer shell 11 and is connected to the dust collection pipe 14 to capture dust and small impurities contained in the particles during the even sliding of the raw materials. The dust collection box 12 is fixed to the outer shell 11. Inside, the core component of the vacuum system, the suction end 15, collects the dust and impurities captured by the suction end 15. The filter cartridge 13, fixed inside the vacuum chamber 12, filters the air within the chamber, trapping dust and impurities inside while clean air is exhausted through the filter cartridge 13. The suction pipe 14 connects the suction end 15 and the vacuum chamber 12, ensuring that the dust and impurities captured by the suction end 15 can smoothly enter the vacuum chamber 12. The vacuum blower 16, fixed inside the housing 6, extends its air inlet into the vacuum chamber 12 to generate suction, drawing the dust and impurities captured by the suction end 15 into the vacuum chamber 12. The air duct 17 connects the air outlet of the vacuum blower 16 to the outside of the housing 6, serving to circulate the air from the vacuum blower. The clean air discharged from the 16th chamber is discharged outside the housing 6. The raw material enters the housing 6 through the feed hopper 7 and slides down the inclined plate 9 onto the material dispersing component 10. The material dispersing component 10 disperses the raw material, ensuring that it falls evenly downwards under gravity. The dust collector 16 is started, generating suction. The dust collector 15 and the dust collector 14 capture the dust and small impurities contained in the particulate material during the even fall of the raw material and suck them into the dust collection box 12. The dust and impurities are filtered by the filter cartridge 13 in the dust collection box 12. The clean air is discharged through the filter cartridge 13 and the air outlet of the dust collector 16, and is discharged from the housing 6 through the air duct 17, thereby removing impurities and dust from the raw material and improving the quality and performance of the product.

[0022] Please see Figure 3 and Figure 4The housing 6 contains a storage bin 18 located below one side of the inclined plate 9. A cylinder 19 is also located inside the housing 6, with its inlet connected to the outlet of the storage bin 18. The outlet of the cylinder 19 is connected to one end of the discharge pipe 8. An auger conveyor shaft 20 is rotatably mounted inside the cylinder 19. A second motor 21 is fixedly mounted outside the cylinder 19, with its output end fixedly connected to one end of the auger conveyor shaft 20. The storage bin 18, located below one side of the inclined plate 9, is used to temporarily store the dispersed and purified raw materials. The cylinder 19 serves as a conveying channel for the purified raw materials, transporting them from the inlet to the outlet via the rotation of the auger conveyor shaft 20. The auger conveyor shaft 20 serves as the power source for raw material conveying. Through the rotation of its spiral blades, the raw material is conveyed inside the cylinder 19. Motor 21 provides power to the auger conveyor shaft 20, ensuring its continuous and stable rotation, thereby completing the conveying of raw materials. The raw material enters the shell 6 through the feed hopper 7, and after being dispersed and purified by the inclined plate 9 and the material dispersing component 10, it falls into the storage box 18. The raw material in the storage box 18 enters the feed inlet of the cylinder 19 through its discharge port. Motor 21 starts, driving the auger conveyor shaft 20 to rotate, conveying the raw material inside the cylinder 19. The conveyed raw material enters the discharge pipe 8 from the discharge port of the cylinder 19 and is finally conveyed to the feeding hopper 3 for use by the screw extrusion mechanism 2.

[0023] Working principle: Raw materials enter the housing 6 through the feed hopper 7 and slide down the inclined plate 9 onto the material dispersing component 10. The material dispersing component 10 disperses the raw materials, ensuring that they fall evenly downwards under gravity. The dust collector 16 starts, generating suction. The dust collector 15 and the dust collection pipe 14 capture dust and small impurities contained in the raw materials during their even descent and suck them into the dust collection box 12. The dust and impurities are filtered by the filter cartridge 13 in the dust collection box 12. Clean air passes through the filter cartridge 13 and the exhaust air from the dust collector 16. The raw material is discharged from the end and exits the shell 6 through the air duct 17. After dispersion and purification, the raw material falls into the storage box 18. The raw material in the storage box 18 enters the feed port of the cylinder 19 through its discharge port. The motor 21 starts and drives the auger conveyor shaft 20 to rotate, conveying the raw material inside the cylinder 19. The conveyed raw material enters the discharge pipe 8 from the discharge port of the cylinder 19 and is finally conveyed to the inside of the feeding hopper 3 for use by the screw extrusion mechanism 2, thereby removing impurities and dust from the raw material, improving the purity of the raw material, and improving the quality and performance of the product.
