Technical Field

[0002] Plastic pipes are tubular materials made of plastic.

Plastic pipes are widely used in building water supply and drainage, municipal water supply and drainage, agricultural irrigation, industrial fluid transportation and other fields. In the construction field, traditional metal pipes are gradually replaced by plastic pipes due to their shortcomings such as easy rust, heavy weight, and complex installation. Plastic pipes can not only meet the requirements of building water supply and drainage, but also reduce the weight of buildings and improve construction efficiency. In municipal engineering, the corrosion resistance of plastic pipes makes it very suitable for water supply and drainage systems. It has great advantages. It can effectively resist the erosion of chemicals and microorganisms in the soil and extend the service life of the pipeline. In agricultural irrigation, the flexibility and lightness of plastic pipes make the installation and maintenance of irrigation systems more convenient. At the same time, the weather resistance of plastic pipes can also adapt to different climatic conditions. In the industrial field, plastic pipes can transport various chemical liquids and gases. Their corrosion resistance and wear resistance can ensure the smooth progress of industrial production. The current production process of plastic pipes is relatively complicated. Therefore, a plastic pipe production device is particularly needed.

The bottom frames inside the box are connected by a buffer rod. As the top frame descends, the sliding shaft at one end of the buffer rod slides in the second slide groove.

As the pipe continues to enter, the buffer plate, under the action of the buffer rod, realizes the slow descent of the pipe, ensuring that the pipe can be evenly cooled during the cooling process, thereby improving the forming effect.

[0023] See also Figure 1-6 The present invention provides a technical solution: a plastic pipe production device, comprising a workbench 1, a supporting leg 2 is fixedly connected to the bottom surface of the workbench 1, a cabinet 3 is fixedly connected to one end of the workbench 1, a cabinet door 4 is installed on the surface of the cabinet 3, an extrusion box 5 is fixedly connected to the upper surface of the workbench 1, a material box 6 is fixedly connected to the upper surface of the extrusion box 5, an air motor 7 is fixedly connected to the upper surface of one end of the workbench 1, a rotating shaft 8 is fixedly connected to the inner end surface of the air motor 7, a spiral rod 9 is fixedly connected to the one end surface of the rotating shaft 8, a heating strip 10 is arranged on the inner wall surface of the extrusion box 5, a discharge pipe 11 is fixedly connected to one end surface of the extrusion box 5, a heat dissipation fin 12 is installed on the outer wall surface of the discharge pipe 11, a mold pipe 13 is fixedly connected to the bottom surface of the discharge pipe 11, a buffer mechanism 14 is arranged on the upper surface of the workbench 1, and a cutting mechanism 15 is arranged inside the cabinet 3;

[0024] The buffer mechanism 14 includes a cooling box 1401, a first slide groove 1402, a buffer plate 1403, a first slider 1404, a first slide bar 1405, a bottom frame 1406, a top frame 1407, a second slide groove 1408, a fixed shaft 1409, a buffer bar 1410 and a sliding shaft 1411. The upper surface of the workbench 1 is fixedly connected with the cooling box 1401, the inner wall surface of the cooling box 1401 is provided with a first slide groove 1402, the inner wall surface of the cooling box 1401 is slidably connected with the buffer plate 1403, the two end surfaces of the buffer plate 1403 are fixedly connected with the first slider 1404, the surface of the buffer plate 1403 is penetrated by the first slide bar 1405, and the cooling box 1401 is fixedly connected with the first slide groove 1402. The bottom surface of the inner part of the box 1401 is fixedly connected with a bottom frame 1406, the bottom surface of the buffer plate 1403 is fixedly connected with a top frame 1407, the surfaces of the bottom frame 1406 and the top frame 1407 are both provided with a second slide groove 1408, the surfaces of the bottom frame 1406 and the top frame 1407 are both fixedly connected with a fixed shaft 1409, the surface of the fixed shaft 1409 is rotatably connected with a buffer rod 1410, the other end surface of the buffer rod 1410 is fixedly connected with a sliding shaft 1411, the sliding shaft 1411 drives the buffer rod 1410 to slide in the second slide groove 1408, through the setting of the buffer mechanism 14, when the extruded plastic pipe is extruded from the mold pipe 13, first The pipe enters the cooling box 1401. At this time, the pipe falls on the buffer plate 1403. Since the buffer plate 1403 is slidably connected to the first slide groove 1402 on the inner wall of the cooling box 1401 through the first slider 1404, and the first slide bar 1405 runs through the surface of the buffer plate 1403, the buffer plate 1403 can move up and down within a certain range. When the pipe falls on the buffer plate 1403, the buffer plate 1403 moves downward under the action of gravity, and the top frame 1407 at the bottom of the buffer plate 1403 also descends. The top frame 1407 and the bottom frame 1406 at the bottom of the cooling box 1401 are connected by the buffer rod 1410. As the top frame 1407 moves downward, the top frame 1407 moves downward. The sliding shaft 1411 at one end of the buffer rod 1410 slides in the second slide groove 1408. Since the buffer rod 1410 is rotatably connected to the fixed shaft 1409, when the top frame 1407 descends, the buffer rod 1410 gradually unfolds to play a buffering role. At the same time, the slow descent of the buffer plate 1403 allows the pipe to gradually enter the coolant in the cooling box 1401, avoiding the bending deformation caused by the rapid cooling of the pipe when it falls directly to the bottom of the cooling box. As the pipe continues to enter, the buffer plate 1403, under the action of the buffer rod 1410, realizes the slow descent of the pipe, ensuring that the pipe can be evenly cooled during the cooling process, thereby improving the molding effect.

[0025] Furthermore, the support legs 2 are provided in multiple groups on the bottom surface of the workbench 1 and are symmetrically arranged with respect to the central axis of the workbench 1. The arrangement of the support legs 2 can provide a stable and uniform supporting force for the workbench 1. During the operation of the plastic pipe production device, operations such as extrusion and cooling will generate certain vibrations and pressures. Multiple groups of symmetrically distributed support legs 2 can effectively disperse these forces to ensure that the workbench 1 always remains stable without tilting or shaking. This is very important for ensuring the stability and accuracy of the entire production process, especially in key links such as extrusion and cutting. The stability of the workbench 1 directly affects the quality and dimensional accuracy of the plastic pipe.

[0026] Furthermore, the position of the first slider 1404 corresponds to the position of the first chute 1402, and the outer wall size of the first slider 1404 matches the inner wall size of the first chute 1402. Through the first chute 1402 and the arrangement of the first slider 1404, the buffer plate 1403 can slide stably in the cooling box 1401. When the plastic pipe falls on the buffer plate 1403, the buffer plate 1403 needs to move up and down to achieve the buffering effect. The cooperation of the first slider 1404 and the first chute 1402 ensures that the moving direction of the buffer plate 1403 is always vertical without offset or jamming, which helps to ensure the stability and reliability of the buffering effect, so that the pipe can smoothly enter the coolant in the cooling box 1401, and avoid damage to the pipe or uneven cooling due to the unstable movement of the buffer plate 1403.

[0027] Furthermore, two groups of buffer rods 1410 are arranged on the surface of the bottom frame 1406 and the top frame 1407, and are distributed in a cross shape. The arrangement of the buffer rods 1410 greatly enhances the buffering effect of the buffer mechanism 14. When the pipe falls on the buffer plate 1403, the top frame 1407 descends, and the buffer rods 1410 begin to play a role. The two groups of buffer rods 1410 distributed in a cross shape can provide support and buffering force from different directions, so that the buffer plate 1403 descends more smoothly. This uniform buffering force can effectively disperse the gravity of the pipe and reduce the impact on the bottom of the cooling box 1401. At the same time, it can also avoid deformation of the pipe due to excessive local force. In addition, the buffer rods 1410 distributed in a cross shape also increase the structural stability of the entire buffer mechanism 14, thereby improving the durability and reliability of the equipment.

[0028] Furthermore, the cutting mechanism 15 includes a fixed plate 1501, a first fixed block 1502, a first motor 1503, a threaded rod 1504, a first moving block 1505, a clamping block 1506, a first limiting block 1507, a fixed box 1508, a limiting groove 1509, a clamping table 1510, an electric push rod 1511, a fixed rod 1512, a second slider 1513, a second fixed block 1514, a second slider 1515, a second motor 1516, a screw rod 1517, a second moving block 1518, a second limiting block 1519, a limiting rod 1520 and a cutting knife 1521. The inner bottom surface of the cabinet 3 is fixedly connected to the fixed plate 1501, the upper surface of the fixed plate 1501 is fixedly connected to the first fixed block 1502, and the first fixed The fixed block 1502 is fixedly connected to the first motor 1503 on one end surface, the first motor 1503 is fixedly connected to the threaded rod 1504 on one end surface, the first moving block 1505 is slidably connected to the outer wall surface of the threaded rod 1504, the surface of the first moving block 1505 is fixedly connected to the clamping block 1506, the bottom surface of one end of the first moving block 1505 is fixedly connected to the first limit block 1507, the upper surface of one end of the fixed plate 1501 is fixedly connected to the fixed box 1508, the surface of the fixed box 1508 is provided with a limit groove 1509, the upper surface of the fixed plate 1501 is fixedly connected to the clamping table 1510, the inner top surface of the cabinet 3 is fixedly connected to the electric push rod 1511, and the bottom surface of the electric push rod 1511 is fixedly connected to the fixed The fixed rod 1512 has a second slider 1513 fixedly connected to both ends of the fixed rod 1512. The inner two side surfaces of the cabinet 3 are fixedly connected to second fixed blocks 1514. The surface of the second fixed block 1514 is fixedly connected to a second slide bar 1515. The second slide bar 1513 drives the fixed rod 1512 to slide on the surface of the second slide bar 1515. The bottom end surface of the fixed rod 1512 is fixedly connected to a second motor 1516. The end surface of the second motor 1516 is fixedly connected to a screw rod 1517. The surface of the screw rod 1517 is slidably connected to a second moving block 1518. The upper surface of the second moving block 1518 is fixedly connected to a second limiting block 1519. The inner side of the fixed rod 1512 is fixedly connected to a limiting rod 1520. The second moving block 15 18 slides on the surface of the limiting rod 1520 through the second limiting block 1519, and the bottom surface of the second moving block 1518 is fixedly connected with a cutting knife 1521. Through the setting of the cutting mechanism 15, when the plastic pipe production reaches a certain length and needs to be cut, the first motor 1503 is started, and the first motor 1503 drives the threaded rod 1504 to rotate. Since the first moving block 1505 is slidably connected with the threaded rod 1504, and the first limiting block 1507 at the bottom of the first moving block 1505 is restricted in the limiting groove 1509 on the surface of the fixed box 1508, the first moving block 1505 can only move along the axial direction of the threaded rod 1504, and the clamping block 1506 on the first moving block 1505 moves accordingly to cooperate with the clamping table 1510.The plastic pipe is clamped and fixed, then the electric push rod 1511 is started, the electric push rod 1511 pushes the fixing rod 1512 to move downward, and the second sliders 1513 at both ends of the fixing rod 1512 slide on the surface of the second slide rod 1515 on the second fixing blocks 1514 on both sides of the cabinet 3 to ensure that the fixing rod 1512 descends vertically and stably. When the fixing rod 1512 descends to a suitable position, the second motor 1516 is started, the second motor 1516 drives the screw rod 1517 to rotate, the second moving block 1518 is slidably connected with the screw rod 1517, and the second The second limit block 1519 above the moving block 1518 is restricted to slide on the surface of the limit rod 1520 inside the fixed rod 1512, so that the second moving block 1518 can only move along the axial direction of the screw rod 1517, and the cutting knife 1521 at the bottom of the second moving block 1518 moves accordingly to cut the clamped plastic pipe. Through such a workflow, the cutting mechanism 15 can accurately and efficiently cut the plastic pipe to ensure that the length of the pipe meets the production requirements, thereby improving the automation and production efficiency of the plastic pipe production device.

[0029] Furthermore, the threads of the threaded rod 1504 are symmetrically distributed, and the outer dimensions of the first limit block 1507 match the inner wall dimensions of the limit groove 1509. Through the arrangement of the threaded rod 1504, the first limit block 1507 and the limit groove 1509, the threads of the threaded rod 1504 are symmetrically distributed, so that the movement of the first moving block 1505 on the threaded rod 1504 is more stable. The symmetrically distributed threads can ensure that the first moving block 1505 is evenly stressed during the movement and will not be biased to one side, so that when clamping the plastic pipe, it can provide a more stable The clamping force can prevent the pipe from shifting during the cutting process. The outer dimensions of the first limit block 1507 are consistent with the inner wall dimensions of the limit groove 1509, ensuring the stability and accuracy of the first moving block 1505 during the movement. The first limit block 1507 slides in the limit groove 1509, limiting the moving direction of the first moving block 1505 so that it can only move along the axial direction of the threaded rod 1504, avoiding deviation or shaking. This is crucial for accurately moving the clamping block 1506 to the appropriate position and clamping the plastic pipe, thereby ensuring the accuracy and quality of the cutting.

[0030] Furthermore, the fixed rod 1512 slides up and down on the surface of the second slide bar 1515 through the electric push rod 1511 and the second slider 1513, and the second motor 1516 and the screw rod 1517 cooperate with each other to form a rotating structure. Through the arrangement of the electric push rod 1511, the fixed rod 1512, the second slider 1513, the second slide bar 1515, the second motor 1516 and the screw rod 1517, the fixed rod 1512 slides up and down on the surface of the second slide bar 1515 through the electric push rod 1511 and the second slider 1513, so that the cutting knife 1521 can accurately reach the cutting position. The electric push rod 1511 provides a stable power to ensure that the fixed rod 1512 can move vertically up and down, and the sliding of the second slider 1513 on the second slide bar 1515 The stability and linearity of the movement of the fixed rod 1512 are guaranteed to avoid tilting or offset, so that the cutting knife 1521 can maintain the correct cutting angle and depth when cutting the plastic pipe, thereby improving the quality and efficiency of cutting. The second motor 1516 and the screw rod 1517 cooperate with each other to form a rotating structure, which provides power for the horizontal movement of the cutting knife 1521. The second motor 1516 drives the screw rod 1517 to rotate, so that the second moving block 1518 can move along the axial direction of the screw rod 1517. This rotating structure can accurately control the moving distance and speed of the cutting knife 1521, ensuring the accuracy and consistency of cutting. At the same time, it also improves the degree of automation of the cutting mechanism 15 and reduces the errors and labor intensity of manual operation.

[0031] Working principle: First, add the plastic raw material into the material box 6, and the raw material enters the extrusion box 5 under the action of gravity, start the pneumatic motor 7, and the pneumatic motor 7 drives the rotating shaft 8 to rotate, and then the rotating shaft 8 drives the screw rod 9 to rotate, and the heating strip 10 on the inner wall of the extrusion box 5 heats the raw material to melt it. The screw rod 9 pushes the molten plastic raw material forward during the rotation process and extrude it from the discharge pipe 11 at one end of the extrusion box 5. The heat dissipation fins 12 on the outer wall of the discharge pipe 11 preliminarily cool the extruded plastic to prevent the plastic from overheating and deformation. The extruded plastic enters the mold pipe 13 from the discharge pipe 11 to form a plastic pipe of a specific shape. The plastic pipe extruded from the mold pipe 13 enters the cooling box 1401, and the pipe first falls on the buffer plate 1403, and the buffer plate 14 03 moves downward under the action of gravity. Since the first sliders 1404 at both ends of the buffer plate 1403 are slidably connected with the first slide groove 1402 on the inner wall of the cooling box 1401, and the first slide rod 1405 runs through the surface of the buffer plate 1403, the buffer plate 1403 can move up and down vertically and stably within a certain range. As the top frame 1407 at the bottom of the buffer plate 1403 descends, the buffer rod 1410 between the top frame 1407 and the bottom frame 1406 at the bottom of the cooling box 1401 begins to play a role. The sliding shaft 1411 at one end of the buffer rod 1410 slides in the second slide groove 1408. Since the buffer rod 1410 is rotatably connected with the fixed shaft 1409, when the top frame 1407 descends, the two groups of buffer rods 1410 distributed in a "cross" shape are 410 is gradually unfolded to play a buffering role, so that the pipe can slowly enter the coolant in the cooling box 1401, avoiding bending deformation caused by rapid cooling, ensuring that the pipe can be evenly cooled during the cooling process, and improving the molding effect. When the plastic pipe production reaches a certain length and needs to be cut, the first motor 1503 is started, and the first motor 1503 drives the threaded rod 1504 to rotate. Since the first moving block 1505 is slidably connected to the threaded rod 1504, and the first limiting block 1507 at the bottom of the first moving block 1505 is limited in the limiting groove 1509 on the surface of the fixing box 1508, the first moving block 1505 can only move along the axial direction of the threaded rod 1504, and the clamping block 1501 on the first moving block 1505 506 moves accordingly and cooperates with the clamping table 1510 to clamp and fix the plastic pipe. Then, the electric push rod 1511 is started, and the electric push rod 1511 pushes the fixing rod 1512 to move downward. The second sliders 1513 at both ends of the fixing rod 1512 slide on the surfaces of the second slide bars 1515 on the second fixing blocks 1514 on both sides of the interior of the cabinet 3 to ensure that the fixing rod 1512 descends vertically and stably. When the fixing rod 1512 descends to a suitable position, the second motor 1516 is started, and the second motor 1516 drives the screw rod 1517 to rotate, and the second moving block 1518 is slidably connected to the screw rod 1517, and the second limit block 1519 above the second moving block 1518 is limited to slide on the surface of the limit rod 1520 on the inner side of the fixing rod 1512.The second moving block 1518 can only move along the axial direction of the screw rod 1517, and the cutting knife 1521 at the bottom of the second moving block 1518 moves accordingly to cut the clamped plastic pipe. The multiple groups of support legs 2 at the bottom of the workbench 1 are symmetrically arranged with the central axis of the workbench 1 to provide a stable and uniform support force for the entire device. During the operation of the plastic pipe production device, the vibration and pressure generated by operations such as extrusion, cooling and cutting can be effectively dispersed by the multiple groups of support legs 2 to ensure that the workbench 1 always remains stable without tilting or shaking.
