Technical Field

[0001] The present invention relates to the technical field of water pipe processing, in particular to a forming device and a processing method for prefabricating and embedding a pipe joint on a PE pipe. Background Art

[0002] Agricultural irrigation is an important link in ensuring agricultural production. The efficient transportation of water resources is directly related to the growth and yield of crops. In modern agriculture, water pipes have become the core components of the irrigation system. Traditional water transportation methods have problems such as water evaporation and leakage, and are inefficient. The use of water pipes can significantly reduce these losses.

[0003] Water pipes for agricultural irrigation mainly include traditional PVC pipes, PE polyethylene pipes, composite pipes and hoses. Among them, PE polyethylene pipes have good flexibility, corrosion resistance, light weight, easy transportation and installation, and are widely used as basic water pipes for agricultural irrigation.

[0004] Prefabricated pipe joint water pipe refers to a product in which the pipe joint is directly embedded or connected to the pipe during the pipe production process. Under the current processing technology and equipment level, the production of prefabricated pipe joint water pipe still has the following deficiencies: insufficient standardization, lack of unified standards for manufacturers, resulting in inconsistent joint specifications, dimensions and material properties, making it difficult to use them in different systems, insufficient design of the combined installation precision of pipes and joints, affecting the connection quality and service life; low automation level, many manufacturers still use manual or semi-automatic processing methods, such as manual welding or bonding, with low production efficiency and difficulty in ensuring quality stability, the lack of automated equipment limits large-scale production, especially in the key links of joint inlay and pipe forming; low processing efficiency, existing processing methods usually require multiple steps, and the connection between each step is not smooth enough, resulting in a long production cycle, high energy consumption and high material loss also increase processing costs, which is not conducive to large-scale promotion. Summary of the Invention

[0005] In order to solve the problems of insufficient standard precision, low automation level and low production efficiency in the production of prefabricated pipe joints for water pipes, the present invention provides a forming device and a processing method for prefabricating embedded pipe joints on PE pipes.

[0006] On the one hand, the present invention provides a forming device for prefabricating an embedded pipe joint on a PE pipe, which adopts the following technical solution:

[0007] A forming device for prefabricating an embedded pipe joint on a PE pipe, comprising:

[0008] Positioning mechanism, used to position and control the PE pipes used for conveying to the processing location;

[0009] A processing mechanism is arranged at the processing position to inlay the pipe joint on the PE pipe;

[0010] The processing mechanism includes a hole cutting assembly, a hot melting assembly, and an installation assembly, which respectively perform hole cutting on the PE pipe, heating and melting the PE pipe at the contact position with the pipe joint, and installing the combined PE pipe and pipe joint.

[0011] A feeding mechanism is arranged on one side of the positioning mechanism and the processing mechanism to deliver the pipe joint to the pickup position of the processing mechanism.

[0012] Through the automatic positioning, cutting, heating, and installation processes, the need for manual intervention is significantly reduced, and the overall production efficiency is improved. This automated process can shorten the production cycle and realize mass production. Precise positioning and the processing mechanism are conducive to the consistency of the installation position and quality of each joint. The precise control of the hole cutting assembly and the hot melting assembly ensures the tight combination between the pipe and the joint, reducing the risk of water leakage or loosening. The automated feeding and processing processes reduce the dependence on manual labor, thereby reducing labor costs. In addition, precise processing reduces material waste, further reducing production costs. The equipment can be easily adjusted or programmed to adapt to different specifications of PE pipes and joints, meeting different production needs. The flexible modular design makes it easier to maintain and upgrade the equipment.

[0013] Further, the positioning mechanism includes a positioning clamp and a conveying wheel arranged side by side. The positioning clamp controls the clamping and fixing of the PE pipe, and the conveying wheel controls and drives the conveying of the PE pipe.

[0014] The positioning clamp can firmly clamp and fix the PE pipe, which is conducive to preventing displacement of the pipe during the processing process. This facilitates each step of the cutting, welding, and installation operations to be performed at the accurate position. The conveying wheel is responsible for driving the conveying of the PE pipe. Its design can facilitate the stability and continuity of the pipe during the conveying process. This stable conveying can effectively reduce the vibration or deviation of the pipe during the conveying process, improving the processing precision. The automatic positioning and conveying system reduces the difficulty and complexity of manual operation. The positioning clamp has a certain adjustable range, which can adapt to PE pipes of different diameters and lengths, increasing the versatility and flexibility of the equipment.

The movable clamp head is precisely controlled by the clamp cylinder and can be flexibly close to or away from the fixed clamp head, thereby realizing adaptive clamping of pipes of different diameters, which is conducive to preventing the pipe from loosening or sliding during processing. The pressing roller cooperates with the rotation operation of the conveying wheel and provides reliable pressure by the pressing cylinder, which is conducive to the pipe being tightly attached to the conveying wheel during conveying to avoid deviation or slipping during conveying. The combination design of the conveying wheel and the pressing roller ensures that the pipe always maintains linear motion during conveying through the smooth rotation of the bearing and the active adjustment of the pressing cylinder, which is conducive to high precision of the processing position. The cylinder control system simplifies the operation process, and the movement of the movable clamp head and the pressing roller is realized by automatic cylinders without manual adjustment, which reduces the operation difficulty and improves the automation level of the equipment. The flexible adjustment of the clamp cylinder and the pressing cylinder enables the equipment to quickly complete the clamping and conveying preparation of the pipe, improving the work efficiency. The efficient cooperation of the conveying wheel and the pressing roller ensures the stability and consistency of pipe conveying, thereby improving the quality of joint installation and reducing the scrap rate.

The conveying wheel chains are meshed with the tension sprocket, which can adjust the tightness of the chains to ensure that the tension of the chains is in the best state during operation, thereby preventing the chains from falling off or loosening and improving the transmission efficiency and conveying stability.

The precise movement control of the displacement assembly enables seamless connection between processes, avoiding the time waste and error accumulation caused by traditional manual adjustment or step-by-step operation. The moving cylinder controls the sliding position of the moving frame on the moving track through extension and contraction, which can realize accurate positioning of the hole cutting, hot melting and mounting assemblies, and is beneficial to the accurate processing position of each process.
