Description

Technical Field

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

[0002] Agricultural irrigation is an important link to ensure 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 irrigation systems. 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 shortcomings: insufficient standardization, lack of unified standards for manufacturers, resulting in inconsistent joint specifications, sizes 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 level of automation, many manufacturers still use manual or semi-automatic processing methods, such as manual welding or bonding, with low production efficiency and difficult to ensure 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 problems 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 accuracy, low automation level and low production efficiency in the production of prefabricated pipe joints for water pipes, the present invention provides a molding device and a processing method for prefabricating embedded pipe joints on PE pipes.

[0006] On the one hand, the present invention provides a molding device for prefabricating an embedded pipe joint on a PE pipe, which adopts the following technical solution: A forming device for prefabricating an inlaid pipe joint on a PE pipe, comprising: Positioning mechanism, used to position and control the PE pipe for conveying and processing to the processing position; A processing mechanism, wherein the processing mechanism is controlled and movable and installed at the processing position, and is used for embedding the pipe joint on the PE pipe; The processing mechanism includes a hole cutting component, a hot melt component and an installation component, and respectively performs cutting holes on the PE pipe, heating and melting the contact part between the PE pipe and the pipe joint, and installing the combined PE pipe and the pipe joint; A feeding mechanism is installed on one side of the positioning mechanism and the processing mechanism, and is used to transport the pipe joint to the picking position of the processing mechanism.

[0007] Through the automated 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 achieve mass production. The precise positioning and processing mechanism is conducive to the installation position and quality consistency of each joint. The precise control of the hole cutting component and the hot melt component ensures a tight fit between the pipe and the joint, reducing the risk of leakage or loosening. The automated loading and processing process reduces dependence on manual labor, thereby reducing labor costs. At the same time, precise processing reduces material waste and further reduces production costs. The equipment can adapt to PE pipes and joints of different specifications through simple adjustment or programming to meet different production needs. The flexible module design makes equipment maintenance and upgrades more convenient.

[0008] Furthermore, the positioning mechanism includes a positioning fixture and a conveying wheel, the positioning fixture and the conveying wheel are arranged side by side, the positioning fixture controls the clamping and fixing of the PE pipe, and the conveying wheel controls and drives the conveying of the PE pipe.

[0009] The positioning fixture can firmly clamp and fix the PE pipe, which is beneficial to prevent the pipe from being displaced during the processing, and is conducive to each step of the subsequent cutting, welding and installation operations being carried out in the correct position. The conveying wheel is responsible for driving the conveying of the PE pipe. Its design can be beneficial to the stability and continuity of the pipe during the conveying process. This smooth conveying can effectively reduce the vibration or deviation of the pipe during the conveying process and improve the processing accuracy. The automated positioning and conveying system reduces the difficulty and complexity of manual operation. The positioning fixture has a certain adjustable range and can adapt to PE pipes of different diameters and lengths, increasing the versatility and flexibility of the equipment.

[0010] Furthermore, the positioning fixture includes a fixed chuck and a movable chuck, and the fixed chuck and the movable chuck are installed correspondingly up and down. The fixed chuck is fixedly installed and supports the PE pipe, and the movable chuck is movably installed by the clamp cylinder and is controlled by the clamp cylinder to move closer to and away from the fixed chuck. The conveying wheel is fixed by the wheel seat and rotatably installed on the wheel seat through the bearing. A clamping roller is movably installed above the conveying wheel, and the clamping roller is movably installed by the clamping cylinder and is controlled by the clamping cylinder to move closer to and away from the conveying wheel.

[0011] The fixed chuck provides a solid support that can hold the PE pipe, which helps the pipe to remain stable during processing. The mobile chuck is precisely controlled by the clamp cylinder and can be flexibly moved close to or away from the fixed chuck, thereby achieving adaptive clamping of pipes of different diameters, which helps the pipe not to loosen or slip during processing. The clamping roller cooperates with the rotation of the conveying wheel and provides reliable pressure through the clamping cylinder, which helps the pipe to always be close to the conveying wheel during transportation, avoiding deviation or slipping during transportation. The combined design of the conveying wheel and the clamping roller ensures smooth rotation of the bearing and the clamping cylinder. The movable adjustment enables the pipe to always maintain linear motion during the conveying process, which is beneficial to the high precision of the processing position. The cylinder control system simplifies the operation process. The movement of the mobile chuck and the clamping roller is realized by the automatic cylinder, without manual adjustment, which reduces the difficulty of operation and improves the automation level of the equipment. The flexible adjustment of the clamp cylinder and the clamping 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 clamping roller ensures the stability and consistency of the pipe conveying, thereby improving the quality of the joint installation and reducing the scrap rate.

[0012] Furthermore, the conveying wheels include two groups and are respectively installed on the front and rear sides of the processing position. The two groups of conveying wheels are connected to each other through a conveying wheel chain. One group of conveying wheels is connected to the rotating spindle of the conveying wheel motor through a coupling. The conveying wheel chain is meshed with a tensioning sprocket. A supporting roller is provided at the processing position between the two groups of conveying wheels. The supporting roller supports the PE pipe at the PE pipe processing position.

[0013] The two sets of output wheels are connected by synchronous transmission through the conveyor wheel chain, which is conducive to the consistent rotation speed of the front and rear conveyor wheels, avoiding the slippage or deviation of PE pipes during transportation due to speed difference. The conveyor wheel chain is meshed and connected through the tensioning sprocket. The tensioning sprocket can adjust the tightness of the chain to ensure that the tension of the chain is in the best state during operation, avoid chain falling off or loosening, and improve transmission efficiency and transportation stability. The combined design of the front and rear conveyor wheels can adapt to PE pipes of different lengths, with greater flexibility and a wider range of applications. The setting of the support roller avoids damage to the equipment or safety hazards caused by pipe sagging due to gravity or unstable transportation.

[0014] Furthermore, the positioning mechanism also includes a measuring component, which includes a measuring wheel and a laser locator. The measuring wheel is pressed against the PE pipe and follows the PE pipe in transmission. The measuring wheel is connected to an encoder, which monitors the rotation of the measuring wheel and further calculates the transmission length of the PE pipe. The laser locator is arranged in a row with the conveying wheel and emits laser toward the PE pipe to detect the end face position of the PE pipe.

[0015] The measuring wheel is pressed tightly against the PE pipe and moves with it. The encoder monitors the rotation of the measuring wheel in real time and accurately calculates the conveying length of the PE pipe based on the rotation data. This design can continuously track the movement of the pipe during the processing, which is beneficial to the accuracy of length measurement. The high-resolution data provided by the encoder can achieve precise control of the pipe length, meet high-precision processing requirements, and avoid processing quality problems caused by length errors. The laser locator is aligned with the conveying wheel and emits a laser to the PE pipe to detect its end face position. The laser locator can quickly and accurately identify the position of the pipe. The combination of the measuring wheel and the laser locator realizes the automatic monitoring of the pipe length and position, reduces the frequency of manual measurement and adjustment, and improves processing efficiency.

[0016] Furthermore, the hole cutting assembly, hot melt assembly and installation assembly are all installed on the shift assembly and follow the movement controlled by the shift assembly. The shift assembly includes a moving frame, a moving rail and a moving cylinder. The moving frame is slidably installed on the moving rail. The moving frame is connected to the moving cylinder and slides on the moving rail through the telescopic control of the moving cylinder. The hole cutting assembly, hot melt assembly and installation assembly are arranged on the moving frame in sequence along the sliding direction of the moving frame.

[0017] The hole cutting component, hot melt component and installation component are arranged in sequence on the mobile frame. Through the control of the shifting component, continuous processing of multiple processes can be realized, which reduces the switching time between components and improves the processing efficiency. The precise movement control of the shifting component enables seamless connection between each process and avoids the time waste and error accumulation caused by traditional manual adjustment or step-by-step operation. The mobile cylinder controls the sliding position of the mobile frame on the mobile track by telescoping, which can realize the precise positioning of the hole cutting, hot melt and installation components, which is conducive to the accurate processing position of each process. The hole cutting component, hot melt component and installation component are all independent modules, and the functional configuration of the components can be flexibly adjusted according to production needs to adapt to the processing of PE pipes of different types or specifications. The mobile frame is slidably installed on the mobile track and maintains straight line operation during movement, reducing the processing instability caused by deviation of the running track.

[0018] Furthermore, the hole cutting assembly includes a hole cutting knife and a hole cutting lifting cylinder, the hole cutting knife is movably lifted and installed on the mobile frame by the hole cutting lifting cylinder, the hole cutting knife is connected to the telescopic end of the hole cutting lifting cylinder through the lifting knife frame, a blower is installed on the lifting knife frame, the blower is arranged on one side of the hole cutting knife, and a waste trough is arranged on the other side of the hole cutting knife, the hot melt assembly includes an upper heating head and a lower heating head, the upper heating head is movably lifted and installed on the mobile frame by the hot melt lifting cylinder, and the lower heating head is fixedly installed on one side of the PE pipe processing position, the installation assembly includes a clamp and an installation lifting cylinder, the clamp is movably lifted and installed on the mobile frame by the installation lifting cylinder, the spacing between the clamp and the upper heating head is equal to the spacing between the upper heating head and the hole cutting knife, and is equal to the spacing between the lower heating head and the PE pipe processing position, the hole cutting knife, the upper heating head and the clamp are aligned with the PE pipe processing position in sequence under the drive of the mobile frame.

[0019] The hole cutting knife, upper heating head and clamping claw are arranged in sequence on a mobile frame. As the mobile frame moves, they can be aligned with the PE pipe processing position in sequence, thereby realizing continuous hole cutting, hot melting and installation operations, reducing the intermediate process conversion time and improving processing efficiency. The hole cutting lifting cylinder and the hot melting lifting cylinder respectively control the vertical movement of the hole cutting knife and the upper heating head to avoid mutual interference during movement, thereby improving the controllability of the processing steps. The blower is installed on one side of the hole cutting knife, which can blow away the waste chips generated during the hole cutting process to avoid waste accumulation affecting the processing accuracy and quality.

[0020] Furthermore, the feeding mechanism includes a vibration plate and a feeding rail, the feeding rail is connected to the conveying discharge end of the vibration plate and receives the pipe joints arranged in a selected direction from the vibration plate, the conveying end of the feeding rail is a material shifting position and is aligned with the clamping claw, positioning strips are respectively arranged on both sides of the upper surface of the feeding rail, the positioning strip at the material shifting position at the conveying end of the feeding rail is notched, and a feeding cylinder is installed at the notch of the positioning strip on one side, the feeding cylinder controls the front end to fill the notch of the positioning strip, and an optical fiber locator is installed at the material shifting position at the conveying end of the feeding rail.

[0021] The vibration plate can automatically select and arrange the pipe joints, which is conducive to each pipe joint being in the correct direction and position when entering the feeding track, greatly reducing manual intervention and improving loading efficiency. The feeding track is connected to the conveying and discharging end of the vibration plate, which is conducive to the pipe joints to maintain the correct direction during transportation. The design on both sides of the positioning bar provides additional guidance and positioning support to prevent the pipe joints from shifting during transportation. The optical fiber locator is installed at the shifting position at the conveying end of the feeding track, which is conducive to each pipe joint. Accurate detection can be achieved when it reaches the specified position, improving the overall positioning accuracy. The gap in the positioning bar at the shifting position at the end of the feeding track allows the pipe joint to have a certain adjustment space when positioning, avoiding the jamming problem caused by dimensional deviation. The feeding cylinder is responsible for pushing the front end to fill the gap in the positioning bar, and can fix the pipe joint after it is positioned, which is conducive to its stability during the material transfer process. The shifting position at the conveying end of the feeding track is aligned with the clamping claw activity, which is conducive to the efficient transfer of the pipe joint to the next process, reducing the intermediate conversion time and improving the overall production efficiency.

[0022] Furthermore, a supporting mechanism is installed at the bottom or side of the positioning mechanism, the processing mechanism and the feeding mechanism, and the supporting mechanism includes a workbench and a conveying roller frame. The positioning mechanism, the processing mechanism and the feeding mechanism are installed on the workbench and fixed to the ground through the workbench. Conveying roller frames are installed and connected on both sides of the workbench, and the upper surface of the conveying roller frame is aligned with the processing position of the processing mechanism.

[0023] The workbench provides a stable installation platform for the positioning mechanism, processing mechanism and feeding mechanism. By fixing it on the ground, it is beneficial to the stability of the entire system during operation and reduces processing errors caused by equipment vibration or unevenness. The upper surface of the conveyor roller frame is aligned with the processing position of the processing mechanism, which is beneficial for the material to be smoothly conveyed from the feeding mechanism to the processing position. The modular design of the workbench and conveyor roller frame allows flexible adjustment of the system layout, and can be reconfigured according to production needs and space conditions to adapt to different production environments.

[0024] On the other hand, the present invention provides a method for prefabricating an embedded pipe joint on a PE pipe, which adopts the following technical solution: A processing method for prefabricating an inlaid pipe joint on a PE pipe, using the above-mentioned molding device for prefabricating an inlaid pipe joint on a PE pipe, comprises the following processing steps: The PE pipe is transported and positioned to the predetermined processing position through the positioning mechanism, and during the processing, the PE pipe is automatically controlled to move intermittently and equidistantly according to the preset pipe joint installation spacing; The pipe joint is transported and positioned to the predetermined material taking position of the processing mechanism through the feeding mechanism; The PE pipe is automatically cut, melted and butted in sequence by the processing mechanism, wherein the hot melt component used for melting heats and melts the cutting edge of the PE pipe and the outer edge of the pipe joint installation at the same time.

[0025] PE pipes are moved intermittently and equidistantly through the positioning mechanism, which is conducive to the accurate installation of pipe joints according to the preset spacing, reduces human operation errors, and improves production efficiency. The entire process from pipe positioning, pipe joint loading to hole cutting, melting, and docking is automated, reducing manual participation and greatly improving production efficiency. The loading mechanism is conducive to the accurate delivery of pipe joints to the predetermined material picking position of the processing mechanism.

[0033] The following is combined with Figure 1-6 The present invention is described in further detail. Example 1

[0034] The embodiment of the present invention discloses a forming device for prefabricating an embedded pipe joint on a PE pipe, referring to Figure 1 and 2 ,include: Positioning mechanism 1, used for positioning and controlling the PE pipe for conveying and processing to the processing position; Processing mechanism 2, the processing mechanism 2 is controlled and movably installed at the processing position, and is used to embed the pipe joint on the PE pipe; The processing mechanism 2 includes a hole cutting component 22, a hot melt component 23 and an installation component 24, and performs cutting holes on the PE pipe, heating and melting the contact part between the PE pipe and the pipe joint, and installing the combined PE pipe and the pipe joint respectively; The feeding mechanism 3 is installed on one side of the positioning mechanism 1 and the processing mechanism 2, and is used to transport the pipe joint to the picking position of the processing mechanism 2.

[0035] The positioning mechanism 1 is responsible for conveying and accurately positioning the PE pipe to the processing position. The positioning mechanism 1 automatically controls the PE pipe to move intermittently and equidistantly according to the preset pipe joint installation spacing through the conveying device to ensure that each section of the pipe is processed at the correct position; The feeding mechanism 3 is installed on one side of the positioning mechanism 1 and the processing mechanism 2, and is responsible for conveying the pipe joint to the predetermined material picking position of the processing mechanism 2. The feeding mechanism 3 ensures that the pipe joint can be accurately picked up by the processing mechanism 2, and is ready for subsequent installation operations; The hole cutting component 22 first performs a hole cutting operation on the positioned PE pipe to ensure that an accurate hole is formed on the pipe to prepare for the subsequent installation of the pipe joint. After the hole cutting is completed, the hot melt component 23 simultaneously heats and melts the edge of the PE pipe hole and the outer edge of the pipe joint, thereby ensuring that the materials can form a firm connection after heating, thereby improving the sealing and durability of the joint. After the heating and melting are completed, the installation component 24 is responsible for accurately installing the pipe joint onto the PE pipe to ensure the firmness and accuracy of the installation.

[0036] After the PE pipe and the pipe joint are connected, the positioning mechanism 1 continues to push the pipe to proceed to the next stage of processing, and the above steps are repeated. Example 2

[0037] On the basis of Example 1, add: Reference Figure 2 The positioning mechanism 1 includes a positioning fixture 11 and a conveying wheel 12, which are arranged side by side. The positioning fixture 11 controls the clamping and fixing of the PE pipe, and the conveying wheel 12 controls and drives the conveying of the PE pipe.

[0038] The positioning fixture 11 and the conveying wheel 12 are started alternately. When the positioning fixture 11 releases the PE pipe, the conveying wheel 12 starts to convey the PE pipe. After the PE pipe is conveyed to the right place, the positioning fixture 11 clamps the PE pipe.

[0039] Reference Figure 3 and Figure 5 The positioning fixture 11 includes a fixed chuck 111 and a movable chuck 112, which are installed correspondingly up and down. The fixed chuck 111 is fixedly installed and supports the PE pipe, and the movable chuck 112 is installed and moved by the fixture cylinder 113 and controlled by the fixture cylinder 113 to move close to and away from the fixed chuck 111; The conveying wheel 12 is fixedly mounted by a wheel seat 121 and rotatably mounted on the wheel seat 121 through a bearing. A clamping roller 13 is movably mounted above the conveying wheel 12 . The clamping roller 13 is movably mounted by a clamping cylinder 131 and is controlled to move closer to and away from the conveying wheel 12 by the clamping cylinder 131 .

[0040] The fixed clamp 111 and the movable clamp 112 are both V-shaped and butted against each other, so as to facilitate clamping of PE pipes of different specifications and sizes.

[0041] The conveying wheel 12 is narrow in the center and wider on both sides, so as to increase the contact area with the PE pipe, improve the stability of transmission and reduce slippage.

[0042] The clamping roller 13 is composed of two rollers arranged in a V shape, which can clamp the PE pipe and reduce the shaking of the PE pipe.

[0043] Reference Figure 4 The conveying wheels 12 include two groups and are respectively installed on the front and rear sides of the processing position. The two groups of conveying wheels 12 are connected to each other through a conveying wheel chain 123. One group of conveying wheels 12 is connected to the rotating spindle of the conveying wheel motor 122 through a coupling. The conveying wheel chain 123 is meshed and connected with a tensioning sprocket 124. A supporting roller 125 is provided at the processing position between the two groups of conveying wheels 12. The supporting roller 125 supports the PE pipe at the PE pipe processing position.

[0044] Reference Figure 3-Figure 6 The positioning mechanism 1 also includes a measuring component 14, which includes a measuring wheel 141 and a laser locator 143. The measuring wheel 141 is pressed against the PE pipe and follows the PE pipe to be transported. The measuring wheel 141 is connected to an encoder 142. The encoder 142 monitors the rotation of the measuring wheel 141 and further calculates the transport length of the PE pipe. The laser locator 143 is arranged in a row with the conveying wheel 12 and emits laser toward the PE pipe to detect the end surface position of the PE pipe.

[0045] The positioning fixture 11 is installed near the initial end of the PE pipe transportation, and the laser positioner 143 is installed near the final end of the PE pipe transportation.

[0046] The distance between the laser locator 143 and the PE pipe processing position is fixed, for example, 200mm. When the laser locator 143 detects the end face of the PE pipe, the first processing position to be processed at this time is 200mm away from the end face. When the first processing position to be processed is 300mm away from the end face, after the laser locator 143 is positioned to the end face of the PE pipe, the conveying wheel 12 drives the PE pipe to be conveyed another 100mm, and so on. Example 3

[0047] On the basis of Example 1, add: Reference Figure 3 and Figure 4 The hole cutting assembly 22, the hot melt assembly 23 and the installation assembly 24 are all installed on the displacement assembly 21 and follow the displacement assembly 21 to control the movement; The shifting assembly 21 includes a moving frame 211, a moving rail 212 and a moving cylinder 213.

The hole cutting assembly 22, the hot melt assembly 23 and the installation assembly 24 are arranged on the moving frame 211 in sequence along the sliding direction of the moving frame 211.

[0048] The movable cylinder 213 drags the hole cutting component 22, the hot melt component 23 and the installation component 24 twice. Initially, the hole cutting component 22 is aligned with the processing position of the PE pipe to make a hole. Then, the movable cylinder 213 drives the hot melt component 23 to align with the hole at the processing position of the PE pipe to perform hot melt treatment. Then, the movable cylinder 213 drives the installation component 24 to align with the processing position of the PE pipe to make a hole after hot melt treatment to install the pipe joint.

[0049] Reference Figure 3-Figure 6 The hole cutting assembly 22 includes a hole cutting knife 221 and a hole cutting lifting cylinder 223.

The blower 224 is arranged on one side of the hole cutting knife 221. A waste trough 225 is arranged on the other side of the hole cutting knife 221. The hot melt assembly 23 includes an upper heating head 231 and a lower heating head 233. The upper heating head 231 is movably lifted and installed on the movable frame 211 by a hot melt lifting cylinder 232, and the lower heating head 233 is fixedly installed on one side of the PE pipe processing position. The mounting assembly 24 includes a clamp 241 and an installation lifting cylinder 242. The clamp 241 is movably lifted and lowered on the movable frame 211 by the installation lifting cylinder 242. The distance between the clamp 241 and the upper heating head 231 is equal to the distance between the upper heating head 231 and the hole cutting knife 221, and is also equal to the distance between the lower heating head 233 and the PE pipe processing position. Driven by the movable frame 211, the hole cutting knife 221, the upper heating head 231 and the clamp 241 are aligned with the PE pipe processing position in sequence.

[0050] When the hole cutting knife 221 is facing the processing position of the PE pipe, the clamping claw 241 is facing the material shifting position at the conveying end of the feeding rail 32, and the hole cutting lifting cylinder 223 drives the hole cutting knife 221 to cut holes in the PE pipe, and the installation lifting cylinder 242 drives the clamping claw 241 to clamp the pipe joint.

[0051] When the upper heating head 231 is facing the PE pipe processing position, the clamping claw 241 is facing the lower heating head 233. At this time, the hot melt lifting cylinder 232 and the installation lifting cylinder 242 are started at the same time, and the PE pipe opening and pipe joint heating are performed at the same time.

[0052] After heating and hot melting are completed, quickly install the pipe joint in the opening of the PE pipe. Example 4
