Description

Technical Field

[0001] The utility model relates to the technical field of PE drainage pipe production, in particular to a forming device for PE drainage pipe production. Background Technique

[0002] PE drainage pipes do not rust, so they are ideal pipes to replace ordinary iron water supply pipes. The production process of PE drainage pipes mainly includes raw material selection, extrusion molding, cooling and shaping, cutting and packing, etc. After the selected high-quality raw materials are precisely adjusted and mixed in formula, the raw materials are sent into an extruder for melting and extrusion, and a pipe blank is formed through a die. This process requires strict control of temperature and pressure to ensure uniform wall thickness and smooth surface of the pipeline. The extruded pipe blank is quickly cooled through a cooling water tank to make the pipeline structure stable and achieve a shaping effect. Finally, the shaped pipeline is cut according to a preset length and subjected to quality inspection, and after passing the inspection, it is packed and shipped.

[0003] However, the die head of the existing forming device for PE drainage pipe production is not convenient for disassembly and assembly. After long-term use, the raw materials adhered to the die head need to be regularly disassembled and cleaned, which reduces work efficiency. Moreover, the existing forming device has uneven blanking, which affects the extrusion molding of the pipe blank. To solve the deficiencies of the existing technology, we propose a forming device for PE drainage pipe production. Content of the Utility Model

[0021] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with the specific implementation modes.

[0022] As Figures 1-3 shown, a forming device for producing PE drain pipes includes a main body 1 of the forming device. A first driving motor 2 is detachably installed on one side of the main body 1 of the forming device. One end of the output end of the first driving motor 2 is detachably installed with an extrusion screw 3. One end of the extrusion screw 3 is rotatably connected to one side of the inner wall of the main body 1 of the forming device. A connector 4 is detachably installed on one side of the main body 1 of the forming device. By tightening the tightening set screw 7, the second mounting head 6 is pulled to move towards the chamfered side of the first mounting head 5. The second mounting head 6 drives the limiting ring 8 to tightly abut against one end of the first mounting head 5. Thus, the connector 4 connects the die head 9 through the first mounting head 5, the second mounting head 6, the tightening set screw 7 and the limiting ring 8. By using the chamfer provided on the first mounting head 5 and the tightening set screw 7 to limit the installation of the second mounting head 6, the die head 9 is convenient for disassembly and cleaning, facilitating the operation of the staff and improving the cleaning efficiency.

[0023] As Figure 2 and Figure 4 shown, a feeding assembly 10 is provided on one side of the top of the main body 1 of the forming device. The feeding assembly 10 includes a feeding cylinder 11. One end of the feeding cylinder 11 is connected through the top of one side of the main body 1 of the forming device. Support rods 12 are symmetrically and detachably installed on the inner wall of the feeding cylinder 11. The second driving motor 14 drives the feeding screw 15 to drive the connecting frame 16 to drive the rotating cylinder 17. The rotating cylinder 17 drives the fixed rod 18 to stir the raw materials in the rotating cylinder 17, and then drives the raw materials into the main body 1 of the forming device through the feeding screw 15. By using the rotating cylinder 17 to drive the fixed rod 18 to stir and mix the raw materials, the raw materials are fed more evenly. Also, the feeding screw 15 stably conveys the raw materials into the main body 1 of the forming device, the raw material conveyance in the main body 1 of the forming device is more stable, reducing the cavities generated by the vacancy of raw materials in the main body 1 of the forming device and improving the quality of the pipe blank extruded by the main body 1 of the forming device.

[0024] Working principle

[0025] It should be noted that the present utility model is a forming device for the production of PE drain pipes. When in use, first, the staff pours the raw materials into the feeding cylinder 11. The raw materials enter the rotating cylinder 17 through the feeding cylinder 11. Then, the second driving motor 14 is started. One end of the output end of the second driving motor 14 drives one end of the feeding screw rod 15 to rotate in the feeding cylinder 11. The feeding screw rod 15 drives the connecting frame 16 to drive the rotating cylinder 17 to rotate in the feeding cylinder 11. The rotating cylinder 17 drives the fixed rod 18 to stir the raw materials in the rotating cylinder 17. The raw materials are sent into the main body 1 of the forming device through the feeding cylinder 11 driven by the feeding screw rod 15. The raw materials entering the main body 1 of the forming device are heated. The first driving motor 2 is started. The output end of the first driving motor 2 drives the extrusion screw rod 3 to send the molten raw materials into the connecting head 4. The molten raw materials pass through the connecting head 4 and then enter the connected die head 9 through the first mounting head 5 and are extruded. The molten raw materials extruded through the die head 9 form a tubular blank. By using the rotating cylinder 17 to drive the fixed rod 18 to drive the raw materials to pass through the feeding screw rod 15 evenly, the purpose of more uniform feeding is achieved.

[0026] When disassembling and assembling the die head 9 for cleaning, by turning the fastening set screw 7 so that it no longer abuts against the chamfered side of the first mounting head 5, pull the die head 9 to drive the second mounting head 6 to disengage from the first mounting head 5. Replace the old die head 9 with a new one and clean the old die head 9. Then, pull the new die head 9 to drive the second mounting head 6 to be sleeved on the first mounting head 5. Then tighten the fastening set screw 7. One end of the fastening set screw 7 moves along the chamfered side of the first mounting head 5. The fastening set screw 7 pulls the second mounting head 6 to move towards the chamfered side of the first mounting head 5. The second mounting head 6 drives the limiting ring 8 to closely abut against one end of the first mounting head 5. Thus, the die head 9 is connected by the first mounting head 5, the second mounting head 6, the fastening set screw 7 and the limiting ring 8, achieving the purpose of convenient disassembly and assembly of the die head 9.
