Description

Plastic composite pipe sealing and conveying integrated machine Technical Field The invention relates to the technical field of plastic composite pipe processing, in particular to a plastic composite pipe sealing and conveying integrated machine. Background The plastic composite pipe has the advantages of corrosion resistance, light weight, convenient molding and the like, and is widely applied to the field of fluid transportation and related industries. In the production process of plastic composite pipes, the pipe ports are usually required to be heated and softened and subjected to hot-melting sealing treatment with sealing caps so as to ensure the sealing performance and the use reliability of the pipes. Therefore, the clamping stability, the conveying precision and the port heating uniformity of the plastic composite pipe are required in the sealing process. In the existing plastic composite pipe sealing equipment, common structural forms are usually separated from a conveying mechanism by an independent clamping mechanism. For example, the pipe is clamped by clamping jaws, pressing wheels or a fixed clamping sleeve, and then the axial movement of the pipe is realized by a conveying roller or a pushing mechanism. The structure often needs to clamp for many times or shift the tubular product between different stations in the in-service use, easily causes the axis skew because of repeated location, influences the seal precision, and overall structure is complicated, and the operation continuity is relatively poor. In the aspect of radial clamping of the pipe, a single point or a few pinch rollers are commonly used for clamping the pipe in the prior art, and part of equipment applies clamping force through a spring or an air cylinder. When the pipe diameter is changed or the pipe has slight ellipticity, the clamping mode is difficult to ensure that the stress in all directions is uniform, and the conditions of partial extrusion or insufficient clamping are easy to occur, so that the damage to the surface of the pipe is likely to be caused, and the slip is likely to occur in the conveying or heating process, so that the processing stability is affected. In addition, in the sealing heating process, part of the existing equipment only carries out axial conveying on the plastic composite pipe, continuous and stable autorotation motion is not applied to the pipe, or the pipe is driven to rotate only through external friction, so that the port of the pipe is heated unevenly in the heating process, the problem of partial overheating or insufficient softening easily occurs, and the quality and the consistency of a finished product of the hot-melt sealing are further affected. Meanwhile, for equipment adopting a plurality of groups of pressing wheels or a multi-station conveying structure, most common driving modes in the prior art are independently arranged by each driving unit, and an effective linkage mechanism is lacked. When equipment needs to be adjusted to the pinch roller position according to pipe diameter change, not only the adjustment process is loaded down with trivial details, and the rotation synchronism between the multiunit pinch roller is difficult to guarantee moreover, has further increased equipment debugging degree of difficulty and operation instability. In summary, the existing plastic composite pipe sealing equipment still has the defects in the aspects of clamping and conveying integration degree, radial clamping uniformity, synchronization of a plurality of groups of conveying members, heating uniformity in the sealing heating process and the like, and the comprehensive requirements of structure simplification, operation stability and sealing quality control are difficult to be met. Therefore, it is necessary to provide a plastic composite pipe sealing and conveying integrated machine which has compact structure, integrates clamping and conveying, can realize the linkage of multiple conveying pipe components and ensures the uniform heating of pipe ports, so as to overcome the technical defects. Disclosure of Invention The invention aims to solve the problems that clamping, conveying and heating processes are mutually independent, clamping times are high, positioning consistency is poor, heating of pipe ends is uneven in a heating process, sealing quality stability is poor and the like in the conventional plastic composite pipe sealing equipment. In order to achieve the above purpose, the invention adopts the following technical scheme: The invention provides a plastic composite pipe sealing and conveying integrated machine which comprises a pipe conveying frame, a pipe supporting seat and an electric heating box which are arranged along the same axial direction. The pipe conveying frame is used for carrying out radial clamping, axial conveying and rotation driving on the plastic composite pipe, the pipe supporting seat is used for supporting the plastic composite pipe in the conveying pr
