The two sides of the single groove of the current spiral groove anti-corrosion pipe are designed with a certain inclined surface with a clamp to the axis of the pipe body. After each groove anti-corrosion pipe is cut, polyethylene delamination will appear at the inclined surface, resulting in unqualified anti-corrosion quality. When polyethylene delamination occurs, the pipe body needs to be manually flipped over and heated and repaired with a hot air gun, which is labor-intensive and affects production efficiency.

[0036] The roller 3 can drive the pipe 2 to rotate around its own axis while driving the pipe 2 to move forward in a straight line along its axis.

[0037] The first powered roller conveyor and the second powered roller conveyor adopt existing equipment, and their further structural details are not described in detail here.

[0038] A base 5 is provided on one side of the area between the first powered roller and the second powered roller, and at least one pressing mechanism 6 is installed on the base 5. In this embodiment, the polyethylene in the two rows of grooves of the pipeline 2 is pressed, so two pressing mechanisms 6 are provided, and the two pressing mechanisms 6 are arranged side by side.

[0039] like Figure 5-Figure 8 As shown, the base 5 includes a first support block 5-1 and a second support block 5-2, and a support rod 5-3 is provided between the first support block 5-1 and the second support block 5-2. The axial direction of the support rod 5-3 is parallel to the forward direction of the pipeline 2, and the support rod 5-3 is slidably connected to the bottom ends of the two pressing mechanisms 6, and the pressing mechanisms 6 can slide along the support rod 5-3.

[0040] The structures of the two pressing mechanisms 6 are exactly the same, and one of the pressing mechanisms is used as an example for explanation:

[0041] The pressing mechanism includes a vertical telescopic rod 6-1, the axis of the vertical telescopic rod 6-1 is vertically arranged, and the top end of the vertical telescopic rod 6-1 is slidably connected to a horizontal rod 6-2, the axis of the horizontal rod 6-2 is horizontally arranged and perpendicular to the travel direction of the pipeline 2, and the sliding direction of the horizontal rod 6-2 is perpendicular to the travel direction of the pipeline 2. A roller frame 6-3 is provided at one end of the horizontal rod 6-2 close to the pipeline 2, and the roller frame 6-3 is rotatably connected to a pressure roller 6-4, and the pressure roller 6-4 is used to press the polyethylene in the groove.

[0042] The vertical telescopic rod 6-1 includes a fixed part and a telescopic part, the telescopic part and the fixed part are telescopically connected, a sliding sleeve 6-5 is provided at the bottom end of the fixed part, and the support rod 5-3 passes through the sliding sleeve 6-5 and is slidably connected to the sliding sleeve 6-5.

[0043] Furthermore, the support rod 5-3 and the sliding sleeve 6-5 are slidably connected via a linear bearing, which reduces friction and makes the movement smoother.

[0044] In another embodiment, a sliding groove is provided on the support rod 5-3, and correspondingly, a slider matching the sliding groove is provided on the inner side of the sliding sleeve 6-5, and the slider cooperates with the sliding groove to realize the sliding connection between the support rod and the sliding sleeve.

[0045] A second locking component is provided between the fixed portion and the telescopic portion, and the second locking component is used to lock and fix the fixed portion and the telescopic portion.

[0046] The second locking component adopts a second locking bolt 6-6, which is threadedly connected to the fixed part. The rod of the second locking bolt 6-6 contacts the telescopic part, pressing the telescopic part against the inner side of the fixed part.

[0047] Furthermore, in order to ensure the firmness of the locking between the fixed portion and the telescopic portion, a plurality of second locking bolts 6 - 6 are provided, and preferably two second locking bolts 6 - 6 are provided.

[0048] A sleeve 6-7 is provided at the top of the telescopic portion of the vertical telescopic rod, and the horizontal rod 6-2 passes through the sleeve 6-7 and is slidably connected to the sleeve 6-7. The horizontal rod 6-2 can move along its own axial direction.

[0049] A first locking component is provided between the sleeve 6-7 and the horizontal rod 6-2, and the first locking component is used to lock and fix the sleeve and the horizontal rod.

[0050] The first locking component adopts a first locking bolt 6-8, which is threadedly connected to the wall of the sleeve 6-7. The rod of the first locking bolt 6-8 presses the horizontal rod 6-2 against the inner side of the sleeve 6-7 to fix the horizontal rod 6-2 and the sleeve 6-7.

[0051] A roller frame 6-3 is fixed to the end of the horizontal rod 6-2 close to the pipe 2. The roller frame 6-3 adopts a U-shaped structure, including a first roller frame part and a second roller frame part and a third roller frame part arranged at both ends of the first roller frame part. A roller shaft is provided between the second roller frame part and the third roller frame part, and the roller shaft is rotatably connected to the pressure roller 6-4.

[0055] Adjust the vertical telescopic rod 6-1 so that the position of the pressure roller 6-4 corresponds to the position of the center line of the spiral groove anti-corrosion pipe.

[0056] The first powered roller and the second powered roller drive the pipeline 2 to rotate around its own axis while driving the pipeline 2 to move forward in a straight line along its own axis. When the pipeline 2 reaches the extruder, the operator wraps polyethylene around the outer surface of the spiral grooved pipe to be anti-corrosive.

[0057] When the joint position of the two adjacent spiral groove pipes advances to the corresponding position of the two pressing mechanisms 6, the operator manually pushes the horizontal rod 6-2, so that the pressing roller 6-4 is pressed on the groove 7 position of the two spiral groove pipes, and the first locking bolt 6-8 is tightened. The pressing mechanism 6 moves along the support rod 5-3 with the pipeline 2, and the polyethylene is pressed into the inside of the groove through the pressing roller 6-4 and fits tightly to the groove surface of the spiral groove pipe, ensuring that there are no bubbles and stratification between the polyethylene and the spiral pipe groove slope, thereby ensuring product quality, reducing rework, reducing the labor intensity of the staff, and improving production efficiency.

[0058] In the pressing device of this embodiment, the pressing roller 6-4 and the horizontal rod 6-2 can be adjusted in height through the vertical telescopic rod 6-1, which meets the use requirements of pipes of different specifications, and the applicability of the entire device is high.
