Description

Technical Field

[0001] This utility model relates to the field of outer sheath cutting technology, specifically a bevel cutting device for polyethylene outer sheaths. Background Technology

[0002] Polyethylene outer protective pipes are widely used as outer protective structures in centralized heating pipelines, gas transmission pipelines, water supply and drainage pipelines due to their strong corrosion resistance, excellent insulation performance, light weight, and convenient installation. In actual engineering installations, to achieve a sealed connection between pipelines, the ends of the polyethylene outer protective pipes need to be machined into beveled surfaces at specific angles. This places clear demands on the precision, efficiency, and adaptability of the cutting equipment.

[0003] However, the existing devices mostly use a fixed angle for the cutting blade, which is difficult to meet the needs of different engineering scenarios for special angles. Changing the angle requires disassembling and reassembling parts, which is cumbersome. Utility Model Content

[0004] This utility model provides a beveling device for polyethylene outer protective tubes, which solves the problem that existing devices mostly have a fixed cutting blade angle, making it difficult to meet the needs of special angles in different engineering scenarios, and changing the angle requires disassembling and reassembling parts, which is cumbersome.

[0005] This utility model provides the following technical solution: a beveling device for polyethylene outer protective pipe, including a base plate, and further including: two sets of mounting brackets disposed on the top surface of the base plate, with storage blocks fixedly connected to both sides of the top surface of the base plate; a fixing assembly disposed inside the two sets of mounting brackets, the fixing assembly including two sets of screw rods, two sets of rotary valves, two sets of extrusion blocks and four sets of telescopic rods; a fixing frame disposed on the top surface of the base plate, with a storage rack slidably connected inside the fixing frame, and a slider slidably connected inside the storage rack, the top surface of the slider being provided with a rotating assembly, the rotating assembly including a servo motor, a rotating rod, a rotary encoder and a PLC controller.

[0006] As a preferred embodiment of this utility model, the two sets of screw rods are arranged inside the two sets of mounting brackets, and a rotary valve is fixedly connected to one end of each set of screw rods. A pressing block is rotatably connected to one end of each set of screw rods, and two sets of telescopic rods are fixedly connected to the top surface of each set of pressing blocks.

[0007] In a preferred embodiment of this utility model, the servo motor is mounted on the top surface of the slider, a rotating rod is fixedly connected to one end of the servo motor, a rotary encoder is rotatably connected to the outside of the rotating rod, and one end of the rotary encoder is electrically connected to a PLC controller via a power line.

[0008] As a preferred embodiment of this utility model, one end of the rotating rod is fixedly connected to a housing, and a cutting blade is provided inside the housing.

[0009] As a preferred embodiment of this utility model, a heat dissipation box is fixedly connected to the top surface of the slider, and a hydraulic rod is fixedly connected to one side of the shelf.

[0013] Compared with the prior art, the present invention provides a bevel cutting device for polyethylene outer protective tubes, which has the following beneficial effects: 1. This beveling device for polyethylene outer protective pipes, through the setting of the rotating component, allows for the setting of the required cutting angle on the PLC controller during use. The servo motor is then started, driving the rotating rod to rotate, which in turn drives the cutting blade. A rotary encoder detects the rotation angle. When the desired cutting angle is reached, the encoder transmits the data to the PLC controller, which then controls the servo motor to stop rotating, ensuring the cutting blade precisely stops at the preset cutting angle. This enables flexible and precise adjustment of different beveling angles for the polyethylene outer protective pipe, meeting diverse needs for pipe beveling angles in various construction scenarios. It avoids problems such as misaligned pipe connections due to angle deviations, improving the overall accuracy and efficiency of the cutting operation.

[0014] 2. The oblique cutting device for the polyethylene outer protective pipe, through the setting of the fixing component and the placement block, allows the polyethylene outer protective pipe to be placed on the placement block during cutting. Rotating the rotary valve causes the screw rod to rotate, which in turn pushes the extrusion block to move. The extrusion block fixes the polyethylene outer protective pipe, preventing it from shifting or shaking during the cutting process. This ensures the accuracy of the cutting trajectory and avoids problems such as skewed cuts and dimensional deviations caused by pipe displacement. At the same time, it reduces the labor intensity of manual support and improves the stability and safety of the cutting operation. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

The top surface of each set of pressing blocks 403 is fixedly connected to two sets of telescopic rods 404.

[0020] In this embodiment, when in use, turning the rotary valve 402 will cause the screw rod 401 to rotate. When the screw rod 401 rotates inside the mounting bracket 2, it moves in the vertical direction, pushing the extrusion block 403 to move. The extrusion block 403 fixes the polyethylene outer protective tube. At this time, the telescopic rod 404 is used to limit the extrusion block 403 to prevent the screw rod 401 from rotating and causing the extrusion block 403 to rotate, thereby preventing the outer protective tube from shifting during cutting.

[0021] Specifically, the servo motor 801 is mounted on the top surface of the slider 7. One end of the servo motor 801 is fixedly connected to a rotating rod 802. A rotary encoder 803 is rotatably connected to the outside of the rotating rod 802. One end of the rotary encoder 803 is electrically connected to a PLC controller 804 via a power line.

[0022] In this embodiment, during use, the servo motor 801 drives the rotating rod 802 to rotate, thereby rotating the cutting blade 10 and adjusting the angle of the cutting blade 10. At this time, the PLC controller 804 controls the operation of the rotary encoder 803, which detects the angle of the rotating rod 802, so that the angle of the cutting blade 10 can be adjusted according to the cutting requirements.

[0023] Specifically, one end of the rotating rod 802 is fixedly connected to the outer casing 9, and the inside of the outer casing 9 is provided with a cutting blade 10.

[0024] In this embodiment, the outer shell 9 is used to protect the cutting blade 10, which is used to cut the polyethylene outer sheath.

[0025] Specifically, a heat dissipation housing 11 is fixedly connected to the top surface of the slider 7, and a hydraulic rod 12 is fixedly connected to one side of the shelf 6.

[0026] Specifically, the fixed frame 5 has a threaded rod 13 inside, and one end of the threaded rod 13 is fixedly connected to a rotating motor 14.

[0027] In this embodiment, the rotary motor 14 is used to drive the threaded rod 13 to rotate, thereby enabling height adjustment of the cutting blade 10.

[0028] Specifically, a limiting groove is provided on the outer side of the fixing frame 5, and a storage chassis 15 is fixedly connected to the top surface of the fixing frame 5.

[0029] Specifically, four sets of support legs 16 are fixedly connected to the bottom surface of the base plate 1, and a control box 17 is fixedly connected to one side of the base plate 1.

[0030] The working principle and usage process of this utility model are as follows: When in use, the required cutting angle is set on the PLC controller 804, the servo motor 801 is started, the servo motor 801 rotates and drives the rotating rod 802 to rotate, the rotating rod 802 rotates and drives the cutting blade 10 to rotate, the rotary encoder 803 is used to detect the rotation angle, when the required cutting angle is reached, the rotary encoder 803 transmits the data to the PLC controller 804, the PLC controller 804 controls the servo motor 801 to stop rotating, so that the cutting blade 10 stops precisely at the preset cutting angle position, thereby realizing flexible and precise adjustment of different oblique cutting angles of polyethylene outer protective pipe, meeting the diverse needs of pipe oblique cutting angles in different construction scenarios, avoiding problems such as pipe connection mismatch caused by angle deviation, and improving the overall cutting operation accuracy and efficiency; During cutting, the polyethylene outer protective tube is placed on the placement block 3, and the rotary valve 402 is rotated. The rotation of the rotary valve 402 drives the screw rod 401 to rotate, and the screw rod 401 pushes the extrusion block 403 to move. The extrusion block 403 fixes the polyethylene outer protective tube, so that the polyethylene outer protective tube will not shift or shake during the cutting process, thereby ensuring the accuracy of the cutting trajectory and avoiding problems such as skewed cuts and dimensional deviations caused by pipe displacement. At the same time, it reduces the labor intensity of manual support and improves the stability and safety of the cutting operation.

[0031] In summary, the oblique cutting device for polyethylene outer protective tube, through the arrangement of rotating component 8, fixing component 4 and placement block 3, enables the device to cut the polyethylene outer protective tube into different angles as needed, while also preventing the outer protective tube from shifting during cutting.
