Description

Technical Field

[0001] This utility model relates to the field of PE pipe cutting technology, and in particular to a PE pipe cutting device. Background Technology

[0002] In the field of pipe processing, PE pipes are widely used due to their advantages such as corrosion resistance and good flexibility. With the diversification of engineering needs, the cutting of PE pipes of different specifications is becoming more and more frequent, especially when processing thicker PE pipes, where existing cutting equipment has many shortcomings.

[0003] Currently, traditional PE pipe cutting equipment generally faces difficulties in rotation when cutting thicker PE pipes. Due to the large weight and diameter of thicker PE pipes, the equipment cannot achieve automatic rotation and often requires manual assistance. This is not only inefficient but also poses safety hazards. Furthermore, manual rotation cannot guarantee the stability and uniformity of rotation, resulting in lower cutting accuracy and difficulty in ensuring cutting quality.

[0004] Traditional equipment typically employs a single support method for supporting and moving PE pipes. Either it relies solely on a fixed support structure, which, due to the lack of effective auxiliary structures, makes moving the pipe laborious and prone to misalignment; or, during slitting, the fixed support structure fails to provide adequate conditions for pipe rotation, hindering the smooth operation. This single support method makes the PE pipe slitting and moving process cumbersome and prone to problems like poor movement or unstable slitting, severely limiting the efficiency and quality of the slitting work. Utility Model Content

[0005] The purpose of this utility model is to provide a PE pipe cutting device that solves the problems of traditional PE pipe cutting devices having difficulty rotating automatically when cutting thicker PE pipes, resulting in low cutting efficiency and poor accuracy, as well as the problem of cumbersome operation and unstable cutting due to the single support and movement method.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A PE pipe cutting device, comprising:

[0008] The base is a hollow structure with uprights welded to its surface;

[0009] Multiple sets of rolling components are evenly distributed on the base surface to assist the rotation of the PE pipe;

[0010] Multiple sets of transmission components are evenly arranged on the base surface and alternately distributed with the rolling components to drive the PE pipe to move;

[0011] The cutting assembly, located at the top of the base near the end, is used to cut PE pipes;

[0012] An auxiliary mechanism, located on the surface of the upright, is used to press the PE pipe from above and drive it to rotate;

[0013] The hollow structure of the base is equipped with an adjustment component for adjusting the vertical position of the rolling assembly.

[0014] Preferably, the adjusting component includes a connecting plate and a second electric push rod, the second electric push rod being fixedly installed inside the hollow structure of the base, and its free end being fixedly connected to the connecting plate.

[0015] Preferably, each set of the rolling assembly includes a support rod fixedly mounted on the surface of the connecting plate, the support rod slidingly passing through the top of the base, and its surface is rotatably connected to two rows of rollers distributed symmetrically.

[0016] Preferably, each of the transmission components includes two fixed rods, and a transmission roller is rotatably connected between the two fixed rods. The transmission roller has a larger diameter at both ends and gradually decreases in diameter towards the middle.

[0017] Preferably, the cutting assembly includes a connecting rod fixedly connected to the base, a third electric push rod fixedly mounted on the top of the connecting rod, a cutting machine fixedly mounted on the free end of the third electric push rod, and two limiting rods that slide through the connecting rod fixedly mounted on the top of the cutting machine.

[0018] Preferably, the auxiliary mechanism includes a first electric push rod fixedly installed at the top of the pole, a connecting frame slidably connected to the surface of the pole, the free end of the first electric push rod being fixedly connected to the connecting frame, a pressure roller being rotatably connected to the bottom of the connecting frame, a second transmission disc being fixedly installed on the surface of the pressure roller's shaft, a motor being fixedly installed at the top of the connecting frame, and a first transmission disc being fixedly installed on the motor's output shaft. The first transmission disc and the second transmission disc are connected by a belt drive.

[0019] Preferably, the surfaces of the pressure roller, drum, and transmission roller are all fixedly fitted with anti-slip rubber sleeves.

[0020] This utility model has at least the following beneficial effects:

[0021] Through the coordinated operation of the auxiliary mechanism and the rolling assembly, automatic rotation of the PE pipe is achieved when slitting thicker PE pipes. The pressure roller in the auxiliary mechanism rotates under the drive of a motor, using friction to drive the PE pipe to rotate. The roller of the rolling assembly provides stable support from below and reduces rotational friction. The combination of the two ensures that the PE pipe rotates continuously and stably during the slitting process, greatly reducing the difficulty of slitting and effectively improving slitting efficiency and quality. It can easily handle even large-diameter and heavy PE pipes.

[0022] When the PE pipe needs to be moved, the adjusting component moves the rolling assembly downwards, allowing the PE pipe to fall onto the drive roller. The unique shape of the drive roller, which is large at both ends and small in the middle, provides stable support for the PE pipe, facilitating the direct application of thrust to adjust its position and creating favorable conditions for cutting. This design of alternating support from the drive roller and the drum not only simplifies the operation process but also avoids problems such as poor PE pipe movement or unstable cutting caused by a single support method, making the cutting and moving of the PE pipe more convenient and efficient.

[0033] Reference Figure 1-6 A PE pipe cutting device includes: a base 1, which has a hollow structure and has uprights 2 welded to its surface;

[0034] Multiple sets of rolling components 4 are evenly distributed on the surface of the base 1 to assist the rotation of the PE pipe;

[0035] Multiple sets of transmission components 6 are evenly arranged on the surface of the base 1 and are alternately distributed with the rolling components 4 to drive the PE pipe to move;

[0036] Cutting component 5 is located at the top of base 1 near the end and is used to cut PE pipes;

[0037] Auxiliary mechanism 3, set on the surface of upright 2, is used to press the PE pipe from above and drive it to rotate;

[0038] The hollow structure of the base 1 has an adjustment component inside, which is used to adjust the vertical position of the rolling component 4.

[0039] The base 1, as the basic component, adopts a hollow structure, reserving installation space for internal adjustment components and providing an installation carrier for the auxiliary mechanism 3 via welded uprights 2. Rolling components 4 are evenly distributed on the surface of the base 1. During the slitting process, when the PE tube needs to rotate, the adjustment components move the rolling components 4 upwards, bringing the roller 41 into contact with the PE tube, significantly reducing rotational friction and facilitating smooth rotation of the PE tube. At this time, the PE tube does not contact the drive roller 62. When the PE tube needs to be moved, the adjustment components move the rolling components 4 downwards, causing the PE tube to fall onto the drive roller 62. The drive roller 62's special structural design interacts with the PE tube surface, propelling the PE tube along a predetermined path. The drive component 6 and rolling components 4 are alternately distributed, working together to switch between the two working states of PE tube rotation and movement. The cutting component 5 is installed at the top of the base 1 near the end. When the PE tube moves to the designated position, it can precisely perform the cutting operation to meet the slitting requirements. The auxiliary mechanism 3 is installed on the surface of the upright 2, which can press the PE pipe from above to ensure its stability during the cutting process. It also has the function of driving the PE pipe to rotate, working in conjunction with the rolling assembly 4 to improve the reliability of the PE pipe rotation. The adjustment component is located inside the hollow structure of the base 1. By flexibly adjusting the vertical position of the rolling assembly 4, it can not only adapt to PE pipes of different diameters, but also realize the switching of the PE pipe's working state, effectively enhancing the equipment's versatility and applicability.

[0040] Furthermore, the adjusting components include a connecting plate 7 and a second electric push rod 8, which is fixedly installed inside the hollow structure of the base 1, with its free end fixedly connected to the connecting plate 7.

[0041] The adjusting component consists of a connecting plate 7 and a second electric push rod 8. The second electric push rod 8 is fixedly installed within the hollow structure of the base 1, serving as the power core and converting electrical energy into mechanical energy to achieve telescopic movement. Its free end is fixedly connected to the connecting plate 7. When the second electric push rod 8 telescopically extends or retracts, it drives the connecting plate 7 to move vertically. The connecting plate 7 serves as the mounting carrier for the rolling assembly 4; as the connecting plate 7 moves, the vertical position of the rolling assembly 4 changes accordingly. In actual operation, the operator precisely controls the telescopic length of the second electric push rod 8 according to the slitting process requirements. When the PE pipe needs to rotate, the second electric push rod 8 extends, driving the rolling assembly 4 upwards, allowing the roller 41 to support the PE pipe and disengage it from the transmission roller 62. At this time, the rolling assembly 4 assists in rotation. When the PE pipe needs to be moved, the second electric push rod 8 shortens, driving the rolling assembly 4 downwards, allowing the PE pipe to fall onto the transmission roller 62, which then propels the PE pipe forward. This structural design allows the adjusting component to adapt to PE pipes of different diameters and flexibly switch the working state of the PE pipe, significantly improving the practicality and efficiency of the equipment.

[0042] Furthermore, each set of rolling components 4 includes a support rod 42 fixedly mounted on the surface of the connecting plate 7. The support rod 42 slides through the top of the base 1, and its surface is rotatably connected to two rows of rollers 41 arranged symmetrically.

[0043] Each rolling assembly 4 consists of a support rod 42 and rollers 41. The support rod 42 is fixed to the surface of the connecting plate 7, serving as a support for the rollers 41. It can slide through the top of the base 1, ensuring stability and guidance during vertical movement with the connecting plate 7. The rollers 41 are symmetrically arranged in two rows and rotated on the surface of the support rod 42. When the rolling assembly 4 moves upward and the rollers 41 come into contact with the PE pipe, the rollers 41 can rotate freely on the support rod 42 during the rotation of the PE pipe, greatly reducing the friction between the two and ensuring smooth rotation of the PE pipe. The symmetrical arrangement of the two rows of rollers 41 supports and assists the rotation of the PE pipe from both sides, further enhancing the stability of the PE pipe rotation, avoiding deviation or jamming during the cutting process, and ensuring smooth cutting operations.

[0044] Furthermore, each transmission assembly 6 includes two fixed rods 61, and a transmission roller 62 is rotatably connected between the two fixed rods 61. The diameter of the transmission roller 62 is larger at both ends and gradually decreases towards the middle.

[0045] Each transmission assembly 6 includes two fixed rods 61 and one transmission roller 62. The fixed rods 61 are fixedly mounted on the surface of the base 1 to support the transmission roller 62 and ensure its stable position during operation. The transmission roller 62 is rotatably connected between the two fixed rods 61. Its unique shape, with large diameters at both ends and gradually decreasing in the middle, provides stable support when in contact with the PE pipe. When manually pushing the PE pipe, the rotation of the transmission roller 62 can reduce friction and facilitate adjustment of the PE pipe's position.

[0046] Furthermore, the cutting assembly 5 includes a connecting rod 51 fixedly connected to the base 1. A third electric push rod 52 is fixedly mounted on the top of the connecting rod 51, and a cutting machine 54 is fixedly mounted on the free end of the third electric push rod 52. Two limiting rods 53 that slide through the connecting rod 51 are fixedly mounted on the top of the cutting machine 54. The cutting assembly 5 consists of the connecting rod 51, the third electric push rod 52, the cutting machine 54, and the limiting rods 53. The connecting rod 51 is fixedly connected to the base 1, providing a stable support foundation for the entire cutting assembly 5. The third electric push rod 52 is mounted on the top of the connecting rod 51 and extends and retracts via electrical energy, providing vertical power to the cutting machine 54. The cutting machine 54 is fixed to the free end of the third electric push rod 52 and is the core component for cutting PE pipes. It moves up and down under the drive of the third electric push rod 52 to cut the PE pipe that has reached the cutting position. Two limiting rods 53 are fixed to the top of the cutting machine 54 and slide through the connecting rod 51. Their function is to guide and limit the movement of the cutting machine 54, prevent the cutting machine 54 from deviating or shaking when moving up and down, and ensure that the cutting machine 54 moves accurately in the vertical direction, thereby ensuring the cutting accuracy of PE pipe and improving the cutting quality and working reliability of the slitting equipment.

[0047] Furthermore, the auxiliary mechanism 3 includes a first electric push rod 31 fixedly installed at the top of the upright 2, a connecting frame 32 slidably connected to the surface of the upright 2, the free end of the first electric push rod 31 being fixedly connected to the connecting frame 32, a pressure roller 33 being rotatably connected to the bottom of the connecting frame 32, a second transmission disc 36 being fixedly installed on the surface of the rotating shaft of the pressure roller 33, a motor 34 being fixedly installed at the top of the connecting frame 32, a first transmission disc 35 being fixedly installed on the output shaft of the motor 34, and the first transmission disc 35 and the second transmission disc 36 being connected by belt drive.

[0048] The auxiliary mechanism 3 mainly consists of a first electric push rod 31, a connecting frame 32, a pressure roller 33, a second transmission disc 36, a motor 34, and a first transmission disc 35. The first electric push rod 31 is fixed to the top of the upright 2 and drives the connecting frame 32 to move vertically on the surface of the upright 2 through its telescopic movement. The connecting frame 32 is slidably connected to the upright 2 and connected to the free end of the first electric push rod 31, sliding up and down under the action of the first electric push rod 31. The pressure roller 33 is rotatably connected to the bottom of the connecting frame 32, pressing the PE pipe from above to prevent it from shaking or jumping during the cutting process, ensuring stability. The second transmission disc 36, installed at the shaft of the pressure roller 33, is connected to the first transmission disc 35 on the output shaft of the motor 34 at the top of the connecting frame 32 via a belt drive. After the motor 34 starts, the first transmission disc 35 rotates, which drives the second transmission disc 36 via the belt, and then drives the pressure roller 33 to rotate. When the pressure roller 33 rotates, it drives the PE pipe to rotate synchronously, working in coordination with the rolling assembly 4 to further improve the stability of the PE pipe rotation, providing good assistance for the PE pipe cutting work, ensuring a smooth cutting process and meeting the cutting quality standards.

[0049] Furthermore, the surfaces of the pressure roller 33, the drum 41, and the transmission roller 62 are all fixedly fitted with anti-slip rubber sleeves.

[0050] During equipment operation, the pressure roller 33, drum 41, and drive roller 62 all come into direct contact with the surface of the PE pipe. The use of anti-slip rubber sleeves serves multiple purposes: Firstly, the excellent anti-slip performance of the rubber sleeves increases friction with the PE pipe surface, making the pressure roller 33 more stable when pressing and driving the PE pipe, preventing slippage; the drum 41 better conforms to the PE pipe during auxiliary rotation, ensuring smooth rotation; and the drive roller 62 more effectively transmits power when moving the PE pipe, preventing slippage or jamming. Secondly, the elasticity and cushioning properties of the anti-slip rubber sleeves reduce damage to the PE pipe surface, protecting its surface quality, while also reducing equipment operating noise and vibration, improving equipment stability and service life, and comprehensively enhancing the overall performance and effectiveness of the PE pipe slitting equipment.

[0051] In summary, the PE pipe is first placed on the surface of the transmission roller 62, and the entire transmission roller 62 is adjusted to prevent the PE pipe from contacting the roller 41.

[0052] Manually push the PE pipe so that the position of the PE pipe to be cut is directly below the cutting component 5. Then use the adjusting component to move the entire roller 41 upward. At this time, the roller 41 will push the PE pipe upward so that it does not contact the drive roller 62.

[0053] The first electric push rod 31 in the auxiliary mechanism 3 drives the pressure roller 33 to move down, so that the pressure roller 33 is located at the top of the PE pipe and contacts it to form a squeezing effect, thereby making the PE pipe three-point fixed.

[0054] The third electric push rod 52 in the cutting assembly 5 drives the cutting machine 54 to move down and cut the PE pipe. At the same time, the motor 34 in the auxiliary mechanism 3 is started, which drives the pressure roller 33 to rotate. The pressure roller 33 uses friction to drive the PE pipe to rotate on the roller 41, thereby achieving the purpose of the cutting machine 54 to cut the entire PE pipe.

[0055] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model.
