Description

Technical Field

[0001] The utility model relates to the technical field of composite pipe production, in particular to a heating device for composite pipe production. Background Art

[0002] Currently, during the production process of composite pipes, the composite pipes need to be heated. For example, a wire mesh reinforced composite pipe needs to be heated after being wrapped with the wire mesh so that the wire mesh can be better composited with the core pipe.

[0003] The existing heating device for composite pipe production is composed of a heating tube and a bracket. An electric heating belt is arranged inside the heating tube. The composite pipe passes through the heating tube and the electric heating belt is energized to heat the composite pipe. When the composite pipe passes through the heating tube, the situation of the composite pipe inside the heating tube is not easy to be observed, so the composite pipe is prone to deflection when it moves. If the composite pipe deflects in one direction, it is easy to scratch the inner wall of the heating tube, and then the outer wall of the composite pipe is prone to overheating and softening after being contacted by the electric heating belt, which is not conducive to heating treatment of the composite pipe. For this reason, we propose a heating device for composite pipe production. Utility Model Content

[0004] The purpose of the present invention is to provide a heating device for composite pipe production, so as to solve the problem in the above background technology that the composite pipe is prone to deflection when moving.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a heating device for producing composite pipes, comprising:

[0006] A heating cylinder, wherein a plurality of heating belts are embedded in the inner wall of the heating cylinder, a support block is fixedly connected to the outer circumference of the heating cylinder, and a horizontal column is provided on the side wall of the support block;

[0007] A lower pressing piece, the lower pressing piece is matched with the front side of the heating cylinder, an upper pushing piece is provided at the bottom of the lower pressing piece, an inner piece is embedded in the upper pushing piece, a plurality of rollers are embedded in the inner piece, a vertical screw is passed through the top of the lower pressing piece, a locking ring is provided on the outside of the vertical screw, a fine-tuning hole is opened on the front side wall of the upper pushing piece, and a locking screw is provided on the side wall of the upper pushing piece;

[0008] A cleaning ring is arranged on the rear side of the heating cylinder, a side ring is provided on the side wall of the cleaning ring, a brush ring is provided inside the cleaning ring, a sewage discharge hole is opened at the bottom of the cleaning ring, and a connecting seat is provided on the outer wall of the cleaning ring.

[0009] Preferably, a spring is sleeved on the outside of the vertical screw.

[0010] Preferably, the spring is fitted between the lower pressing piece and the upper pushing piece.

[0011] Preferably, the transverse column fits inside the fine-tuning hole.

[0012] Preferably, the transverse column passes through the side wall of the connecting seat.

[0013] Preferably, grooves are provided between the bristle circles.

[0014] Preferably, the drain hole is fitted into the bottom of the groove.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. The utility model provides a lower pressing piece and an upper pushing piece at both ends of the heating tube. When the composite pipe passes through the interior of the heating tube for heating, the locking ring of the lower pressing piece is rotated so that the lower pressing piece cooperates with the vertical screw to move downward and then cooperates with the upper pushing piece to approach the outer wall of the composite pipe. At this time, the pipe can cooperate with the rolling of the rollers inside the lower pressing piece and the upper pushing piece to perform limit clamping, thereby avoiding the problem that the composite pipe deflects when passing through the heating tube and then scrapes and softens against the inner wall of the heating tube. The composite pipe can pass through the heating device stably without deflection, which is conducive to heating the composite pipe using the heating device for composite pipe production.

[0017] 2. According to the present invention, after the composite pipe passes through the lower pressure piece and the upper push piece on the rear side, the composite pipe enters the cleaning ring and then enters the heating cylinder. At this time, the brush ring inside the cleaning ring brushes the outer wall of the composite pipe, so that the dust on the outer wall of the composite pipe is brushed off and falls into the inside of the groove, and finally can be discharged from the drain hole, thereby cleaning the dust on the outer wall of the composite pipe, avoiding the problem of dust accumulation inside the heating cylinder caused by a lot of dust on the outer wall of the composite pipe during heating, which is beneficial to keeping the inside of the heating cylinder clean with less dust.
