Description

Technical Field

[0001] The utility model relates to the technical field of plastic winding pipe processing, and more specifically to a heating roller device for reinforcing welding of large-caliber HDPE winding pipes. Background Art

[0002] At present, the welding process of plastic wrapped pipe includes welding the plastic wrapped pipe section and the head on the rotary platform using a plastic welding extruder, welding the inside of the plastic wrapped pipe using a long arm welder, and welding special positions on the head using a manual handheld welding gun.

[0003] For example, the prior art discloses a plastic winding pipe welding processing production line, which includes a long-arm welding machine for plastic winding pipes, a rotating platform for rotating pipe fittings, and a plastic welding extruder arranged corresponding to each rotating platform; at least two groups of rotating platforms are arranged in parallel and at intervals, and each rotating platform is slidably connected to a longitudinal guide rail parallel to the axis of the pipe fitting on the rotating platform; the plastic welding extruder, a lifting mechanism for up and down movement and positioning is fixed on the base, and a first working platform corresponding to the welding position of the plastic welding extruder is fixed on the power output end of the lifting mechanism; the long-arm welding machine is slidably connected to a transverse track placed on the front side of the longitudinal guide rail; the plastic welding extruder of this scheme is used for welding pipe sections and heads.

[0004] However, the extrusion process of the prior art determines that the side wall of the profile is a smooth structure. Since the winding tube is formed by extruding and welding large-sized profiles, the welding strength determines the performance of the tube to a large extent. The strength of the welding part of the side wall of the profile with a smooth structure is difficult to ensure, resulting in great risks to the performance of the tube. Therefore, there is a technical problem in the prior art that the side wall welding strength of the winding tube is weak. Utility Model Content

[0005] The utility model aims to overcome the disadvantage of weak side wall welding strength of the winding pipe in the prior art and provide a heating pressure roller device for reinforcing welding of large-diameter HDPE winding pipe.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] A heating pressure roller device for large-diameter HDPE winding pipe reinforcement welding comprises a frame and a pressure roller rotatably arranged on the frame, wherein the surface of the pressure roller is evenly provided with a plurality of protrusions that can roll in contact with the side wall of the winding pipe profile, and the pressure roller can generate heat so that the shape of the protrusions is imprinted on the side wall of the winding pipe profile.

[0008] The utility model discloses a heating pressure roller device for reinforced welding of large-diameter HDPE winding pipe, in which a pressure roller is rotatably arranged on a frame, and a plurality of protrusions which can roll in contact with the side wall of the winding pipe profile are evenly arranged on the surface of the pressure roller. Since the pressure roller can generate heat so that the shape of the protrusions is imprinted on the side wall of the winding pipe profile, the side wall of the smooth winding pipe profile becomes uneven, thereby improving the friction force of the side wall of the winding pipe profile, thereby improving the welding strength of the side wall of the winding pipe profile, improving the overall performance of the winding pipe, and effectively solving the technical problem of weak welding strength of the side wall of the winding pipe in the prior art.

[0009] Furthermore, the two ends of the pressure roller are coaxially provided with limiting columns, the diameter of the limiting columns is larger than the diameter of the pressure roller, and the axial length of the pressure roller is larger than the side wall height of the winding tube profile. Coaxial limiting columns are provided at both ends of the pressure roller. Since the diameter of the limiting columns is larger than the diameter of the pressure roller, the upper and lower end surfaces of the winding tube profile are ensured to be clamped between the limiting columns on both sides, playing a role of limiting guide; and the axial length of the pressure roller is larger than the side wall height of the winding tube profile, ensuring that the upper and lower edges of the side wall of the winding tube profile are fully contacted by the pressure roller.

[0010] Furthermore, the frame is movably provided with a support frame, and a rotating column is provided on the side of the limit column away from the pressure roller, and the rotating columns at both ends are rotatably provided on the support frame. A rotating column is provided on the side of the limit column away from the pressure roller, and the rotating columns at both ends are rotatably provided on the support frame to realize the free rotation of the pressure roller; the support frame is movably provided on the frame to facilitate the movable adjustment of the support frame.

[0011] Furthermore, a heating rod is inserted into the pressure roller, and the top end of the heating rod passes through the limit column and the rotating column. Inserting the heating rod into the pressure roller realizes the heating function, and passing the top end of the heating rod through the limit column and the rotating column facilitates electrical connection to realize electric heating.

[0012] Furthermore, the frame is movably provided with an adjustment column, the support frame is arranged at the end of the adjustment column, the axial direction of the adjustment column is perpendicular to the rotation axis of the pressure roller and the conveying direction of the winding tube profile, and the adjustment column can adjust its position along its own axial direction relative to the frame. Since the outer wall of the pressure roller rolls in contact with the side wall of the winding tube profile, the rotation axis of the pressure roller is perpendicular to the conveying direction of the winding tube profile, and the axial direction of the adjustment column is perpendicular to the rotation axis of the pressure roller and the conveying direction of the winding tube profile, and the adjustment column can adjust its position along its own axial direction relative to the frame, so as to achieve targeted adjustment of the distance from the pressure roller to the side wall of the winding tube profile for winding tube profiles of different sizes.

[0013] Furthermore, an adjustment sleeve is provided at one end of the adjustment column close to the support frame, and the support frame is rotatably connected to the adjustment sleeve, and the rotation axis of the support frame relative to the adjustment sleeve is perpendicular to the rotation axis of the pressure roller and parallel to the conveying direction of the winding tube profile. The support frame is rotatably connected to the adjustment sleeve, and since the rotation axis of the support frame relative to the adjustment sleeve is perpendicular to the rotation axis of the pressure roller and parallel to the conveying direction of the winding tube profile, the side walls of the winding tube profile in different directions can be adapted to rolling contact by adjusting the rotation of the support frame relative to the adjustment sleeve.

[0014] Furthermore, a rotating platform is provided on the side of the support frame away from the pressure roller, and two sets of fixed platforms are provided on the end of the adjustment sleeve away from the adjustment column. The two sets of fixed platforms are respectively provided on both sides of the rotating platform, and bolts are simultaneously passed through the two sets of fixed platforms and the rotating platform and threadedly connected with the nuts on the other side so that the rotating platform can be rotated and adjusted relative to the fixed platform. The two sets of fixed platforms are respectively provided on both sides of the rotating platform to improve the stability of the rotating connection; bolts are simultaneously passed through the two sets of fixed platforms and the rotating platform and threadedly connected with the nuts on the other side to adjust the angle of the rotating platform relative to the fixed platform by adjusting the tightness of the bolts and nuts.

[0015] Furthermore, the adjusting column is threadedly connected to the frame, and the adjusting sleeve is threadedly connected to the adjusting column. The adjusting column is threadedly connected to the frame to achieve the axial position adjustment of the adjusting column relative to the frame; the adjusting sleeve is threadedly connected to the adjusting column to facilitate the secondary adjustment of the angle of the adjusting sleeve after the axial position of the adjusting column is adjusted.

[0016] Furthermore, a hand wheel is provided at one end of the adjusting column away from the adjusting sleeve. The hand wheel is provided at one end of the adjusting column away from the adjusting sleeve to facilitate rotational adjustment of the adjusting column.

[0017] Furthermore, the surface of the pressure roller is evenly distributed with grid-like grooves, and each protrusion is surrounded by four adjacent and intersecting grooves in sequence to form a quadrilateral. Since the surface of the pressure roller is evenly distributed with grid-like grooves, each protrusion is surrounded by four adjacent and intersecting grooves in sequence to form a quadrilateral, which is convenient for processing and has a good anti-slip effect.
