Description

Technical Field

[0001] This utility model relates to the field of PE pipe technology, and more specifically, to PE pipe hot melt processing equipment. Background Technology

[0002] In municipal water supply and drainage, gas transmission, and industrial fluid transport, PE pipes are widely used due to their advantages such as corrosion resistance, long service life, and convenient installation. These applications typically require connecting pipes of different lengths into a complete pipeline system, demanding good sealing and mechanical strength at the joints to ensure the safe and reliable operation of the entire system. Currently, most plastic pipes are joined manually using hot-melt welding. Operators need to manually adjust the pipe position and control the heating temperature and pressure. This method is not only time-consuming and labor-intensive, reducing the efficiency of hot-melt welding, but also prone to problems such as eccentricity and tilting during the connection process due to significant human interference, resulting in large precision errors. This directly affects the quality and strength of the hot-melt joint, thus impacting the normal service life of the plastic pipes and the safety of the system.

[0003] Under current technological conditions, operators lack effective rapid pipe positioning and fixing devices when performing hot-melt butt welding. A significant amount of time is required for manual adjustment and calibration before each connection, and disassembling the equipment after welding is equally time-consuming and labor-intensive. This inefficient operating method not only greatly extends the construction cycle and increases labor costs, but also fails to enable rapid positioning, fixing, and disassembly of the pipes, making it difficult to meet the urgent needs of modern engineering construction for efficient and precise construction.

[0005] In view of the problems existing in the prior art, this utility model provides a PE pipe hot melt processing equipment to solve the technical problems mentioned in the background art.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a PE pipe hot melt processing equipment, including a base, a screw rotatably mounted on the base, a motor fixedly mounted on the outside of the base, an output end of the motor fixedly connected to one end of the screw, a transmission block threadedly connected to the outside of the screw, a connecting rod rotatably mounted on the outer wall of the transmission block, multiple sets of the connecting rod, each with a support block rotatably connected to its bottom end, a pressure plate abutting the top of each set of support blocks, a fixing mechanism between the pressure plate and the support plate, the fixing mechanism including a plug rod and a fixing sleeve, the plug rod being fixed to the top surface of the support block and inserted into the pressure plate, the fixing sleeve being inserted into the top of the plug rod and abutting the top surface of the pressure plate, a snap-fit ​​plate fixedly mounted on the inner wall of the fixing sleeve, multiple sets of snap-fit ​​plates, a snap groove opened on the outer wall of the plug rod, a sliding groove opened on the outer wall of the fixing sleeve, multiple sets of sliding grooves slidably connected to a sliding sleeve, a push plate fixedly mounted on the inner side of the sliding sleeve, multiple sets of push plates, insertion holes opened on each of the multiple sets of pressure plates, and insertion holes being multiple sets and respectively inserted into the plug rod.

[0008] The present invention is further configured such that a limiting plate is fixedly provided on the top surface of the sliding sleeve, and multiple sets of the limiting plate are provided. A rotating sleeve is rotatably provided on the outer wall of the fixed sleeve, and an unlocking groove is provided on the outer wall of the rotating sleeve. The multiple sets of the limiting plates abut against the outer side of the rotating sleeve, which can limit the rotation amplitude of the rotating sleeve, prevent it from rotating excessively, and ensure the stability of the device.

[0009] The present invention is further configured such that a guide plate is fixedly provided on the inner side of the fixed sleeve, and a guide groove is provided on the outer wall of the insertion rod. Multiple sets of the guide plate and the guide groove are provided and slidably connected. The cooperation between the guide plate and the guide groove can effectively guide the movement of the insertion rod and ensure that it does not deviate or get stuck during the sliding process.

[0010] The present invention is further provided that a compression spring is provided between the bottom surface of the sliding sleeve and the fixed sleeve. The compression spring can provide a certain elastic force to ensure the balance and buffer between the sliding sleeve and the fixed sleeve and prevent excessive vibration or damage.

[0011] The present invention is further configured such that a compression spring is connected inside the insertion rod, and an abutment plate is fixedly provided on the top surface of the fixing sleeve. The compression spring can provide a reverse elastic force to ensure that the insertion rod can return to its original position under compression, and the abutment plate further ensures that the insertion rod remains stable during movement.

[0012] The present invention is further configured such that all of the multiple sets of snap-fit ​​plates are spring plates and the tops of all of the multiple sets of push plates are arc-shaped. The elasticity of the spring plates can provide an automatic reset function, and the arc shape can reduce friction when in contact with other components, thereby improving the smoothness of movement and durability.

[0013] The present invention is further configured such that each of the bottom surfaces of the multiple sets of support blocks is fixedly provided with a slider, and a groove is provided on the top surface of the base.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the present invention provides a PE pipe hot melt processing equipment, which has the following beneficial effects:

[0017] 1. This device uses a motor to drive a screw to rotate and drive a transmission block. The connecting rod then pushes multiple sets of support blocks to achieve precise alignment and hot-melt butt welding of PE pipes. This solves the problems of time-consuming, labor-intensive, and inaccurate joints in traditional manual butt welding. At the same time, it adopts a fixing mechanism that combines a plug rod and a fixing sleeve. With the help of a pressure plate, it can quickly and firmly fix the pipes, effectively preventing pipe displacement during hot-melt welding, ensuring the quality of the joints, and greatly improving the working efficiency and connection accuracy of hot-melt butt welding of PE pipes.

[0018] 2. This device features a unique quick-unlocking mechanism. By cooperating with the rotating sleeve and the limiting plate, simply rotating the rotating sleeve will disengage the limiting plate from the abutment state. Then, the compression spring will drive the sliding sleeve to push the push plate to deform and disengage from the slot, thus quickly releasing the fixed sleeve from the insertion rod. The compression spring provides automatic ejection force, allowing the fixed sleeve to quickly disengage from the pressure plate. The entire unlocking process is simple and quick, requiring no complicated operations, and significantly shortening the pipe disassembly time.

[0019] 3. The precise guiding movement of the support block is achieved through the sliding groove and slider on the base, and the precise lifting and lowering of the heating plate assembly is controlled by the electric push rod, making the hot melting and docking process highly automated. At the same time, the elastic design of the snap-fit ​​plate and the arc-shaped push plate ensures the smooth and reliable snap-fit ​​and unlocking process. The design of the guide plate and guide groove ensures the accurate positioning of the fixing sleeve and the insertion rod. These designs together constitute a highly efficient, precise and easy-to-operate PE pipe hot melting processing system, which perfectly solves the problems of unstable pipe fixing, low docking accuracy and complicated operation in the existing technology.

The insert rod 8 is fixed to the support block. The top surface of the 6 is inserted into the pressure plate 7. The fixing sleeve 9 is inserted into the top of the insertion rod 8 and abuts against the top surface of the pressure plate 7. The inner wall of the fixing sleeve 9 is fixedly provided with a snap-fit ​​plate 10. Multiple sets of snap-fit ​​plates 10 are provided. The outer wall of the insertion rod 8 is provided with a snap-fit ​​groove 11. The outer wall of the fixing sleeve 9 is provided with a sliding groove 12.

Multiple sets of limiting plates 16 abut against the outer side of the rotating sleeve 17. The limiting plates 16 limit the rotation amplitude of the rotating sleeve by contacting the rotating sleeve 17, preventing it from rotating excessively and improving the stability of the system.

[0031] A guide plate 19 is fixedly provided on the inner side of the fixed sleeve 9, and a guide groove 20 is provided on the outer wall of the insertion rod 8. Multiple sets of guide plates 19 and guide grooves 20 are provided and slidably connected. The cooperation between the guide plates 19 and guide grooves 20 can ensure that the insertion rod 8 slides smoothly, avoids deviation or jamming, and improves the motion accuracy.

[0032] A compression spring 21 is provided between the bottom surface of the sliding sleeve 13 and the fixed sleeve 9. The compression spring 21 can provide elastic support, ensure the balance between the sliding sleeve 13 and the fixed sleeve 9, and play a buffering role to prevent vibration or damage.

[0033] A compression spring 22 is connected inside the insertion rod 8, and an abutment plate 23 is fixed on the top surface of the fixing sleeve 9. The function of the compression spring 22 is to provide a reverse elastic force to ensure that the insertion rod 8 can return to its original position after being subjected to compression force, while the abutment plate 23 stabilizes the movement of the insertion rod 8 and prevents it from deviating.

[0034] All sets of snap-fit ​​plates 10 are spring plates, and the tops of all sets of push plates 14 are rounded. The spring plates provide elasticity during snap-fit ​​and automatically reset, while the rounded tops of the push plates reduce friction with other components, improving the smoothness of movement and durability.

[0035] Multiple sets of support blocks are fixedly provided with sliders 24 on their bottom surfaces, and the top surface of the base 1 is provided with a sliding groove 25. Multiple sets of sliders 24 are slidably connected in the sliding groove 25. The cooperation between the sliders 24 and the sliding groove 25 ensures the smooth sliding of the support blocks on the base 1, and enhances the stability of the structure and the accuracy of the movement.

[0036] A support frame 26 is fixedly mounted on the base 1. An electric push rod 27 is fixedly mounted on the inner side of the support frame 26. A heating plate assembly 28 is fixedly mounted on the bottom end of the electric push rod 27. The electric push rod 27 provides the necessary power support, while the heating plate assembly 28 ensures that the material is heated evenly during the heating process, thereby improving heating efficiency.

[0037] In this embodiment, during use, the PE pipe to be heat-fused is placed on the support block 6, then the pressure plate 7 is abutted against the top surface of the PE pipe, and the insertion hole 15 is inserted into the insertion rod 8. The fixing sleeve 9 is then inserted into the top of the insertion rod 8. Multiple sets of guide plates 19 are positioned and inserted into the guide groove 20. The top of the insertion rod 8 pushes multiple sets of snap-fit ​​plates 10 to deform. When all sets of snap-fit ​​plates 10 have moved into the slot 11, they reset and abut against the outer wall of the slot 11. The compression spring 22 is compressed by the abutment plate 23, causing the fixing sleeve 9 to snap into the insertion rod 8 and abut against the top surface of the pressure plate 7. The PE pipe is fixed in place. The heating plate assembly 28 can be raised and lowered at any time by pushing the electric push rod 27. The motor 3 is started to drive the screw 2 to rotate. The screw 2 is threadedly engaged with the transmission block 4 and pulls multiple sets of connecting rods 5. The multiple sets of connecting rods 5 pull multiple sets of support blocks 6 to slide along the slide groove 25 through the slider 24. The support blocks 6 drive the PE pipe to move and abut against the heating plate assembly 28. The heating plate assembly 28 heats and melts the PE pipe. Then the electric push rod 27 retracts the heating plate assembly 28. The multiple sets of support blocks 6 drive the PE pipe to move and connect.

[0038] More specifically, when it is necessary to disassemble the PE pipe, rotating the rotating sleeve 17 causes multiple unlocking slots 18 to move to the inside of the limiting plate 16, so that the multiple limiting plates 16 release from contact with the outer wall of the rotating sleeve 17. The compression spring 21 pushes the sliding sleeve 13 to slide along the sliding groove 12, and drives multiple push plates 14 to push multiple snap-fit ​​plates 10 to deform and disengage from the snap-fit ​​groove 11, thereby releasing the snap-fit ​​between the fixing sleeve 9 and the insertion rod 8. The compression spring 22 pushes the abutment plate 23 and causes the fixing sleeve 9 to release from contact with the pressure plate 7. Then the pressure plate 7 and the insertion rod 8 can be separated to disassemble the PE pipe.

[0039] In summary, during the use or operation of the overall equipment: When in use, place the PE pipe to be heat-fused onto the support block 6, then place the pressure plate 7 against the top surface of the PE pipe and insert the insertion hole 15 into the insertion rod 8. Next, insert the fixing sleeve 9 into the top of the insertion rod 8. Position the insertion through multiple sets of guide plates 19 and guide grooves 20, and push multiple sets of snap-fit ​​plates 10 to deform through the top of the insertion rod 8. Once all sets of snap-fit ​​plates 10 have moved into the slot 11, they reset and abut against the outer wall of the slot 11. The compression spring 22 is compressed by the abutment plate 23, causing the fixing sleeve 9 to snap into the insertion rod 8 and abut against the pressure plate 23. The PE pipe is fixed on the top surface of plate 7. The heating plate assembly 28 can be raised and lowered at any time by pushing the electric push rod 27. The motor 3 is started to drive the screw 2 to rotate. The screw 2 is threadedly engaged with the transmission block 4 and pulls multiple sets of connecting rods 5. The multiple sets of connecting rods 5 pull multiple sets of support blocks 6 to slide along the slide groove 25 through the slider 24. The support blocks 6 drive the PE pipe to move and abut against the heating plate assembly 28. The heating plate assembly 28 heat-melts the PE pipe. Then the heating plate assembly 28 is retracted by the electric push rod 27. The multiple sets of support blocks 6 drive the PE pipe to move and connect.

[0040] When it is necessary to disassemble the PE pipe, rotating the rotating sleeve 17 causes multiple unlocking slots 18 to move to the inside of the limiting plate 16, so that the multiple limiting plates 16 release their contact with the outer wall of the rotating sleeve 17. The compression spring 21 pushes the sliding sleeve 13 to slide along the sliding groove 12, and drives multiple push plates 14 to push multiple snap-fit ​​plates 10 to deform and disengage from the snap-fit ​​slot 11, thereby releasing the snap-fit ​​between the fixing sleeve 9 and the insertion rod 8. The compression spring 22 pushes the abutment plate 23, causing the fixing sleeve 9 to release its contact with the pressure plate 7. Then the pressure plate 7 and the insertion rod 8 can be separated, and the PE pipe can be disassembled.
