Description

Technical Field

[0001] This utility model relates to the field of anti-corrosion and heat-insulating pipe production technology, and more specifically, it relates to a polyethylene propulsion structure for anti-corrosion and heat-insulating pipe production. Background Technology

[0002] Corrosion-resistant and heat-insulating pipes are widely used in construction, medicine, petrochemical and other fields for transporting water, steam, petroleum and liquid chemical raw materials. In the processing of these pipes, polyethylene is used. The polyethylene raw material is heated and reshaped to produce the pipes used in the production of heat-insulating pipes. However, polyethylene granules are prone to blockage during feeding, generally requiring a pushing structure to push the material. Existing pushing structures, however, easily affect feeding, are inconvenient to adjust, and the pushing end is easily damaged after prolonged use, making replacement cumbersome. Furthermore, the overall length of the pushing structure is limited for different external feeding funnels, indicating a need for improved practicality. Utility Model Content

[0027] Please see Figures 1-5A polyethylene propulsion structure for the production of anti-corrosion and heat-insulating pipes includes a fixed base 1 with a fixed hole 2, limiting plates 3 at both ends of the fixed base 1, a support plate 4 on top of the fixed base 1, the support plate 4 being rotatably mounted relative to the two limiting plates 3, limiting rods 5 penetrating the two limiting plates 3, limiting holes 6 at both ends of the support plate 4 corresponding to the limiting rods 5, a through groove 7 on the support plate 4, an adjusting plate 8 slidingly mounted inside the through groove 7, a support rod 9 penetrating the adjusting plate 8, a connecting plate 10 at the upper end of the support rod 9, an electric push rod 11 on the upper surface of the adjusting plate 8, the electric push rod 11 being connected to the connecting plate 10, and a detachable mounting sleeve 12 at the bottom of the outer end face of the support rod 9, with multiple sets of mounting sleeves 12 of different models.

[0028] In this embodiment, the fixed base 1 is installed corresponding to the external feeding funnel. The bolts pass through the fixed holes 2 on both sides and are tightened to fix the feeding funnel. When it is necessary to add material, the upper limit rod 5 of the limiting plate 3 is pulled outward, and the support plate 4 is rotated and retracted relative to the limiting plate 3. Material is added through the feeding funnel. After the material is added, the support plate 4 is rotated to the vertical position. After rotating to the vertical position, the limiting rod 5 is inserted into the limiting hole 6 to achieve the limiting and tightening of the vertical position.

[0029] More specifically, when a blockage occurs during the feeding process, the control device has its own control system. The electric push rod 11 drives the connecting plate 10 to rise and fall, and the connecting plate 10 drives the support rod 9 to rise and fall relative to the adjusting plate 8. The sleeve 12 installed on the support rod 9 pushes the polyethylene raw material inside the feeding funnel to avoid blockage.

[0030] Please see Figure 1 and Figure 2 As one implementation method for limiting: each of the two limiting rods 5 is provided with a limiting ring 13 on its outer end, and a spring 14 is provided between the limiting ring 13 and the limiting plate 3.

[0031] Specifically, by grasping the limiting ring 13, the limiting rod 5 is pulled outward, the spring 14 is stretched, and after the support plate 4 rotates to a vertical position, the limiting ring 13 is released, the spring 14 retracts, and the limiting ring 13 drives the limiting rod 5 to reset and insert into the limiting hole 6.

[0032] Please see Figure 1 , Figure 4 and Figure 5 As one embodiment of the mounting sleeve 12: multiple sets of mounting sleeves 12 are symmetrically provided with first threaded holes 15, and the support rod 9 is provided with second threaded holes 16 corresponding to multiple sets of first threaded holes 15. The first threaded holes 15 and the second threaded holes 16 are connected by bolts. Multiple sets of mounting sleeves 12 are symmetrically provided with locking blocks 17, and the support rod 9 is provided with locking grooves 18 corresponding to multiple sets of locking blocks 17.

[0033] Specifically, the mounting sleeve 12 is installed in relation to the support rod 9. The locking block 17 and the slot 18 cooperate to achieve sliding guidance during installation. The first threaded hole 15 and the second threaded hole 16 are locked together by bolts, which facilitates installation and locking, and facilitates material pushing and adjustment.

[0034] Please see Figure 1 , Figure 3 and Figure 4 As one embodiment of the adjusting plate 8: a first locking hole 19 is provided on the upper end face of the support plate 4, and a second locking hole 20 is provided on the adjusting plate 8 corresponding to the first locking hole 19. Multiple second locking holes 20 are spaced apart. The first locking hole 19 and the second locking hole 20 are connected by bolts. Guide blocks 21 are symmetrically provided on the adjusting plate 8. Guide rods 22 are provided on both guide blocks 21. Guide holes 23 are provided on both guide rods 22 on the support plate 4 corresponding to both guide rods 22. Fixing rings 24 are provided on both guide rods 22 corresponding to the support plate 4.

[0035] Specifically, when the adjusting plate 8 slides relative to the through groove 7, the guide rod 22 and the guide hole 23 cooperate to slide and guide, the fixing ring 24 provides anti-detachment protection for the front position, and the guide block 21 provides anti-detachment protection for the rear position. When it slides to the appropriate position, the bolt passes through the first locking hole 19 and the appropriate second locking hole 20 and aligns, and the bolt passes through and is tightened and fixed.

[0036] In summary, the overall equipment is in use:

[0037] When in the installation and adjustment state, select the appropriate installation sleeve 12 according to the usage requirements. The installation sleeve 12 is installed corresponding to the support rod 9. The locking block 17 and the locking groove 18 cooperate to guide the sliding. The bolt passes through the first threaded hole 15 and the second threaded hole 16 and is tightened to fix it. After the installation sleeve 12 is installed, the fixed seat 1 is installed corresponding to the feeding funnel. The bolt passes through the fixing hole 2 of the fixed seat 1 and is installed and locked corresponding to the feeding funnel, which facilitates the installation of feeding funnels of different models.

[0038] When the material pushing position is adjusted, the adjusting plate 8 slides relative to the through groove 7 of the support plate 4. The guide rod 22 and the guide hole 23 cooperate to slide and guide. The guide block 21 provides anti-detachment protection for the rear side, and the fixing ring 24 provides anti-detachment protection for the front side. The adjusting plate 8 drives the support rod 9 to slide to the appropriate position. The bolt passes through the first locking hole 19 and the appropriate second locking hole 20 and is tightened and fixed, which facilitates position adjustment and material pushing adjustment for different models of feeding funnels.

[0039] When in the retraction and adjustment state, grasp the limiting ring 13, pull the limiting rod 5 outward, the spring 14 is stretched, the limiting rod 5 is pulled out from the limiting hole 6, the support plate 4 rotates relative to the limiting plate 3 and retracts, and the feeding operation through the feeding funnel avoids feeding conflict. After the feeding is completed, the support plate 4 rotates and adjusts, grasp the limiting rod 5 and pull it outward, the spring 14 is stretched, after rotating to the vertical state, release the limiting ring 13, the spring 14 retracts, the limiting rod 5 resets and inserts into the limiting hole 6, and the vertical state is locked.
