Description

Technical Field

[0001] This utility model belongs to the field of PP microtube technology, specifically, it relates to a PP microtube edge locking device. Background Technology

[0002] In the manufacturing of plastic pipes, a flaring machine is used to flare the pipe ends for easier connection. Before flaring, the pipe ends are placed in a heating box to soften them. The softened pipe ends are easier to shape. Then, workers send the softened pipe ends into the flaring system for flaring and shaping.

[0003] A document with publication number CN219214091U discloses a pipe flaring device, which includes a mounting frame. A conveying component and a temperature-adjustable flaring component are respectively mounted on both ends of the top of the mounting frame. A fixing component mounted on the top of the mounting frame is also provided between the conveying component and the flaring component. A PLC controller connected to the flaring component and the fixing component is also mounted on the fixing component. A laser receiver connected to the PLC controller is mounted on the fixing component. A laser emitter corresponding to the laser receiver is mounted on the top of the mounting frame. This invention, by enabling temperature adjustment of the flaring component, eliminates the need for heating and softening the pipe in a heating box before flaring. Instead, the flaring component is heated and its temperature is adjusted, thereby improving the quality of pipe flaring and overall pipe quality.

[0004] The aforementioned device expands the pipe through a flaring assembly. However, most existing flaring methods rely on fixed extrusion. If the center shifts during extrusion, the flaring will shift, resulting in uneven inner walls that are easily damaged, thus affecting the quality of the flaring.

[0005] In view of this, this utility model is hereby proposed. Utility Model Content

[0006] To solve the technical problem of pipe flaring, the basic concept of the technical solution adopted by this utility model is as follows: A PP microtube edge-locking device includes a processing component for processing PP microtubes. The processing component includes a base, a drive motor, an active cylinder, a flaring block, and a support block. The drive motor is fixedly connected to the base, the active cylinder is driven by the output end of the drive motor, the flaring block is arranged around the active cylinder, and the support block is arranged on the base.

[0007] In a preferred embodiment of this utility model, a coupling is fixedly connected to the output end of the drive motor, the coupling is fixedly connected to the inner wall of the drive cylinder, a limiting cylinder is fixedly connected to the outside of the drive cylinder, and a cavity exists between the drive cylinder and the limiting cylinder.

[0008] In a preferred embodiment of this utility model, a guide rod is arranged around the cavity between the active cylinder and the limiting cylinder. Each guide rod is fixedly connected to the active cylinder, and one end of the guide rod extends out of the active cylinder.

[0009] In a preferred embodiment of this utility model, heat-conducting blocks are arranged in an array on the guide rod, each heat-conducting block is fixedly connected to the guide rod, and each heat-conducting block abuts against the inner wall of the limiting cylinder.

[0010] In a preferred embodiment of this utility model, each flared block is connected to the active cylinder by fasteners, the extension part of the guide rod is inserted into the inside of the flared block, and the inside of the flared block is hollow.

[0011] In a preferred embodiment of this utility model, a fixed ring is rotatably connected to the active cylinder, a limiting ring is slidably connected to the fixed ring, the limiting ring engages with the limiting cylinder, and a connecting block is slidably connected to the bottom of the limiting ring.

[0012] In a preferred embodiment of this utility model, the connecting block is provided with a miniature cylinder, the output end of the miniature cylinder is fixedly connected to the connecting block, and the miniature cylinder is fixedly connected to the base.

[0013] In a preferred embodiment of this utility model, a large atmospheric cylinder is fixedly connected to the base, and the support block is fixedly connected to the output end of the atmospheric cylinder.

[0014] Compared with the prior art, the present invention has the following advantages: 1. A PP microtube sealing device, in which the flaring block is rotated, pushes the PP microtube toward the flaring block to achieve flaring during rotation. As the flaring block rotates, it generates a stable circle. The flaring speed of the PP microtube is increased by rotational contact and extrusion. With bottom support, the flaring deviation caused by a single extrusion method is avoided.

[0015] 2. This PP microtube edge-locking device restricts the heat transferred by the heat-conducting block from the cylinder, reduces the cooling rate of the PP microtube after it extends into the interior at the end of the PP microtube, and avoids excessive cooling, which could lead to wall breakage and affect the quality of the PP microtube.

[0016] 3. In this PP microtube locking device, a micro cylinder pushes a connecting block through its output end. The connecting block drives a limiting ring to move. The limiting ring and the limiting cylinder are tightly engaged. The limiting ring is helical toothed, which restricts the position of the limiting cylinder and thus restricts the rotation of the active cylinder, making it convenient for loading and unloading PP microtubes.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0021] Please see Figure 1-5 A PP microtube edge-locking device includes a processing component for processing PP microtubes. The processing component includes a base 1, a drive motor 2, an active cylinder 21, a flaring block 24, and a support block 41. The drive motor 2 is fixedly connected to the base 1. The active cylinder 21 is driven by the output end of the drive motor 2. The flaring block 24 is arranged around the active cylinder 21. The support block 41 is arranged on the base 1. Before processing, the PP microtube end is first parallel to the corresponding flaring block 24. Then, the height of the support block 41 is adjusted to place the PP microtube in a horizontal state. Then, the PP microtube end is softened by the heat of the flaring block 24 itself. The drive motor 2 drives the active cylinder 21 and the flaring block 24 to rotate through the output end. As the flaring block 24 rotates, it squeezes and expands the end of the PP microtube. At this time, only manual pushing is needed to complete the flaring of the PP microtube. Under the method of rotating and squeezing to flare, the PP microtube can ensure rapid flaring and that the flaring position does not shift.

[0022] The output end of the drive motor 2 is fixedly connected to a coupling 5, which is fixedly connected to the inner wall of the drive cylinder 21. A limiting cylinder 3 is fixedly connected to the outside of the drive cylinder 21. There is a cavity between the drive cylinder 21 and the limiting cylinder 3. A guide rod 22 is arranged around the cavity between the drive cylinder 21 and the limiting cylinder 3. Each guide rod 22 is fixedly connected to the drive cylinder 21, and one end of the guide rod 22 extends out of the drive cylinder 21. Heat-conducting blocks 23 are arranged in an array on the guide rod 22. Each heat-conducting block 23 is fixedly connected to the guide rod 22, and each heat-conducting block 23 abuts against the inner wall of the limiting cylinder 3. Each flared block 24 is connected to the drive cylinder 21 by fasteners. The extended part of the guide rod 22 is inserted into the inside of the flared block 24. The inside of the flared block 24 is hollow. First, the guide rod 22 is started. The guide rod 22 generates a lot of heat during operation. The guide rod 22 transfers the heat to the heat-conducting block 23 and the flaring block 24, thereby preheating the flaring block 24 and the limiting cylinder 3. Then, after the pipe is placed in a suitable position, the output end of the drive motor 2 cooperates with the coupling 5 to drive the active cylinder 21 to rotate. The rotation of the active cylinder 21 drives the flaring block 24 to rotate. The rotation of the flaring block 24 pushes the PP microtube toward the flaring block 24, realizing flaring during rotation. Because the rotation of the flaring block 24 generates a stable circle, the flaring speed of the PP microtube is increased by rotational contact extrusion. Moreover, with bottom support, the flaring deviation caused by a single extrusion method is avoided. During the rotation, the contact between the flaring block 24 and the tube opening is dynamic and continuous. If there is a slight eccentricity, the force generated by the rotation will have an automatic correction tendency, causing the tube opening to expand evenly in all directions, eventually forming a perfect circular opening centered on the rotation axis. This effectively avoids unilateral compression. The deformation of each point is completed by the continuous and uniform rolling of the rotating flaring block 24, rather than being completed by a one-time hard push. Therefore, the fiber flow is smoother and the inner wall is smoother and more uniform. The flared block 24 itself acts as a heat source for direct processing, eliminating the need for preheating of the PP microtube. It also limits the heat transferred from the heat-conducting block 23 to the cylinder 3, reducing the cooling rate of the PP microtube after it extends into the interior, thus preventing excessive cooling and wall breakage that could affect the quality of the PP microtube. After processing, the PP microtube can be removed.

[0023] Among them, a fixed ring 32 is rotatably connected to the active cylinder 21, a limiting ring 31 is slidably connected to the fixed ring 32, the limiting ring 31 is engaged with the limiting cylinder 3, a connecting block 33 is slidably connected to the bottom of the limiting ring 31, a micro cylinder 34 is provided on the connecting block 33, the output end of the micro cylinder 34 is fixedly connected to the connecting block 33, and the micro cylinder 34 is fixedly connected to the base 1. In processing steps where the rotation of the active cylinder 21 is not required, such as loading and unloading PP microtubes, the micro cylinder 34 pushes the connecting block 33 through the output end. The connecting block 33 drives the limiting ring 31 to move. The limiting ring 31 and the limiting cylinder 3 are tightly engaged, and the limiting ring 31 is helical toothed, which restricts the position of the limiting cylinder 3, thereby restricting the rotation of the active cylinder 21 and facilitating the loading and unloading of PP microtubes.

[0024] Among them, a large air cylinder 4 is fixedly connected to the base 1, and the support block 41 is fixedly connected to the output end of the large air cylinder 4. After the position of the PP microtube is confirmed, the output end of the atmospheric cylinder 4 drives the support block 41 to rise and fall. The support block 41 provides horizontal support for the PP microtube, realizing horizontal processing of the PP microtube and reducing errors.

[0025] Working principle: Before processing, the PP microtube end is first parallel to the corresponding flaring block 24. Then, the height of the support block 41 is adjusted to place the PP microtube in a horizontal position. Subsequently, the flaring block 24 softens the PP microtube end through its own heat. The drive motor 2 drives the active cylinder 21 and the flaring block 24 to rotate through the output end. As the flaring block 24 rotates, it squeezes and expands the end of the PP microtube. At this time, only manual forward pushing is needed to complete the flaring of the PP microtube. Under the rotating and squeezing flaring method, the flaring of the PP microtube can be ensured to be rapid and the flaring position does not shift. First, the guide rod 22 is started. The guide rod 22 generates a lot of heat during operation, and the guide rod 22 transfers the heat. The heat is drawn into the heat-conducting block 23 and the flaring block 24, thereby preheating the flaring block 24 and the limiting cylinder 3. After the pipe is placed in a suitable position, the output end of the drive motor 2, in conjunction with the coupling 5, drives the active cylinder 21 to rotate. The rotation of the active cylinder 21 drives the flaring block 24 to rotate, pushing the PP microtube towards the flaring block 24, achieving flaring during rotation. Because the rotation of the flaring block 24 generates a stable circle, the flaring speed of the PP microtube is increased through rotational contact compression. Furthermore, with bottom support, the flaring deviation caused by a single compression method is avoided. During rotation, the contact between the flaring block 24 and the pipe opening is dynamic and continuous. If a slight deviation exists... The force generated by the rotation has an automatic alignment tendency, causing the tube opening to expand evenly in all directions, ultimately forming a perfectly circular opening centered on the rotation axis. This effectively avoids unilateral compression. The deformation at each point is completed by the continuous and uniform rolling of the rotating flaring block 24, rather than by a one-time hard pressing. Therefore, the fiber flow is smoother, and the inner wall is smoother and more uniform. The flaring block 24 itself acts as a heat source for direct processing, eliminating the need for preheating of the PP microtube. It also limits the heat transferred from the heat-conducting block 23 to the cylinder 3, reducing the cooling rate of the PP microtube after it extends into the interior, preventing excessively rapid cooling and wall fracture. The quality of the PP microtube is affected. After processing, the PP microtube can be removed. In processing steps where the rotation of the active cylinder 21 is not required, such as loading and unloading the PP microtube, the micro cylinder 34 pushes the connecting block 33 through the output end. The connecting block 33 drives the limiting ring 31 to move. The limiting ring 31 and the limiting cylinder 3 are tightly engaged. The limiting ring 31 is helical toothed, which restricts the position of the limiting cylinder 3, thereby restricting the rotation of the active cylinder 21 and facilitating the loading and unloading of the PP microtube. After the position of the PP microtube is confirmed, the output end of the large cylinder 4 drives the support block 41 to rise and fall. The support block 41 provides horizontal support for the PP microtube, realizing horizontal processing of the PP microtube and reducing errors.
