Description

Technical Field

[0001] This utility model relates to the field of thermal insulation pipe technology, specifically a polyethylene resin winding device for thermal insulation pipe production. Background Technology

[0002] Insulated pipes, also known as thermally insulated pipelines, reduce heat loss or cold loss of the transported medium (liquid, gas, steam, etc.). Furthermore, by wrapping the outer layer of the insulated pipe with polyethylene resin, it acquires excellent corrosion resistance, insulation, and mechanical properties, maintaining the stability of its operation.

[0003] For example, a polyethylene resin winding device for producing thermal insulation pipes, with application number CN202420717188.0, includes a workbench, flexible polyethylene resin, a first vertical plate, a second vertical plate, a thermal insulation pipe, an electric push rod, a U-shaped plate, a first pressure roller, and a second pressure roller. The distance between the second pressure roller and the first pressure roller can be adjusted, and the thickness of the flexible polyethylene resin being extruded and conveyed can be adjusted according to the wall thickness of the thermal insulation pipe, and then wound onto the thermal insulation pipe.

[0004] When the aforementioned insulation pipe is wound with polyethylene resin, the thickness of the wound flexible polyethylene resin is adjusted by the distance between the second pressure roller and the first pressure roller. However, the tension of the flexible polyethylene resin cannot be adjusted during winding, and uneven tension during winding can easily lead to air bubbles or wrinkles, thus affecting the winding quality.

[0005] Therefore, we propose a polyethylene resin winding device for the production of thermal insulation pipes to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide a polyethylene resin winding device for the production of thermal insulation pipes, so as to solve the problem mentioned in the background art that the tension of flexible polyethylene resin cannot be adjusted during winding, and the uneven tension during winding of flexible polyethylene resin easily leads to air bubbles or wrinkles, thereby affecting the winding quality.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a polyethylene resin winding device for producing thermal insulation pipes, comprising a base and a fixed block fixedly installed on the upper end of the base, a thermal insulation pipe movably installed on one end of the fixed block, a movable locking block movably installed on the other side of the thermal insulation pipe, a drive screw threadedly connected to the lower end of the movable locking block, an electric push rod fixedly installed on one side of the upper end of the base, a support component fixedly installed on one end of the electric push rod, an adjustment component threadedly installed on the upper end of the support component, and a tensioning component fixedly installed on one side of the outer wall of the support component;

[0008] The support assembly includes a concave support block and an insertion magnetic block fixedly installed in the middle of the lower end of the concave support block. The lower end of the insertion magnetic block is magnetically connected to a sliding block. A first pressure roller is movably installed in the middle of the inner wall of the concave support block near the lower movable shaft. Penetrating grooves are respectively opened on both sides of the upper end of the inner wall of the concave support block, and a connecting groove is opened in the middle of one side of the inner wall of the penetrating groove.

[0009] Preferably, a long groove is formed in the middle of one side of the upper end of the base, and a limiting groove is formed in the middle of both sides of the inner wall of the long groove.

[0010] Preferably, a drive motor is fixedly installed on one side of the outer wall of the fixing block, and an H-shaped cylinder is movably installed at the upper middle part of the fixing block.

[0011] Preferably, right-angled blocks are fixedly installed on both sides of one end of the outer surface of the concave support block, and a through groove is provided in the middle of one side of the outer wall of the right-angled block.

[0012] Preferably, a square magnetic groove is provided at the middle of the upper end of the sliding block, and extension blocks are fixedly installed at the middle of both sides of the outer wall of the sliding block.

[0013] Preferably, the adjusting assembly includes a connecting shaft and a second pressure roller movably mounted on the outer surface of the connecting shaft, with short screws fixedly mounted at both ends of the outer wall of the connecting shaft.

[0014] Preferably, the tensioning assembly includes a threaded rod and circular blocks fixedly installed at the outer ends of the threaded rod, and a roller is movably installed in the middle of the outer surface of the threaded rod.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. Adjust the distance between the first and second pressure rollers to control the winding thickness of the flexible polyethylene resin. Adjust the height of the threaded rod within the through groove to change the roller height and thus adjust the winding tension of the flexible polyethylene resin. Manually clamp the flexible polyethylene resin and spread it at an angle onto the insulation pipe. The electric push rod then drives the concave support block to move along the rotation direction of the insulation pipe to complete the winding process.

[0017] 2. When the electric actuator drives the concave support block to move, the inserted magnetic block at its bottom is fixed in the square magnetic groove by magnetic attraction. The sliding block and the extension block slide along the long groove and the limiting groove, forming a double guiding structure, which effectively improves the moving stability of the concave support block. This design combines magnetic fixing and mechanical limiting to achieve guidance. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0024] Example 1: Please refer to Figures 1-4 A polyethylene resin winding device for producing thermal insulation pipes includes a base 1 and a fixing block 2 fixedly installed on the upper end of the base 1. A thermal insulation pipe 3 is movably installed on one end of the fixing block 2, and a movable locking block 4 is movably installed on the other side of the thermal insulation pipe 3. A drive screw 5 is threadedly connected to the lower end of the movable locking block 4. One end of the drive screw 5 is installed on one end of the inner cavity of the base 1 through a bearing. The movable locking block 4 can be moved by rotating the drive screw 5.

[0025] An electric push rod 6 is fixedly installed on one side of the upper end of the base 1. A support component 7 is fixedly installed on one end of the electric push rod 6. An adjustment component 8 is threadedly installed on the upper end of the support component 7. A tensioning component 9 is fixedly installed on one side of the outer wall of the support component 7.

[0026] A drive motor 21 is fixedly installed on one side of the outer wall of the fixed block 2. An H-shaped cylinder 22 is movably installed at the upper middle part of the fixed block 2. One end of the H-shaped cylinder 22 is fixedly installed with the output end of the drive motor 21, and one end of the heat insulation pipe 3 is movably installed in the inner cavity of the H-shaped cylinder 22.

[0027] By rotating the drive screw 5, the movable locking block 4, which is threadedly connected to its outer surface, is moved. Since the upper middle part of the movable locking block 4 is provided with a semi-circular groove, by inserting one end of the insulation pipe 3 into the inner cavity of the H-shaped cylinder 22, and then rotating the drive screw 5 in the opposite direction to move the movable locking block 4, the other end of the insulation pipe 3 is inserted into the upper middle part of the movable locking block 4, thus completing the movable limiting installation of the insulation pipe 3.

[0028] The electric actuator 6 is configured to push the support assembly 7 to move in position. The electric actuator 6 is a current technology and is not limited here. It can be installed by purchasing commercially available finished products, such as the YB-520 series electric actuator.

[0029] The support assembly 7 includes a concave support block 71 and an insertion magnetic block 72 fixedly installed in the middle of the lower end of the concave support block 71. The lower end of the insertion magnetic block 72 is magnetically connected to a sliding block 73. A first pressure roller 74 is movably installed in the middle of the inner wall of the concave support block 71 near the lower end movable shaft. Penetrating grooves 75 are respectively opened on both sides of the upper end of the inner wall of the concave support block 71. A connecting groove 76 is opened in the middle of one side of the inner wall of the penetrating groove 75.

[0030] The adjusting assembly 8 includes a connecting shaft 81 and a second pressure roller 82 movably mounted on the outer surface of the connecting shaft 81. Short screws 83 are fixedly mounted on both ends of the outer wall of the connecting shaft 81. The connecting shaft 81 is movably mounted in the inner cavity of the through groove 75, and the short screws 83 are movably mounted in the inner cavity of the connecting groove 76 and are fixed by threaded limit by nuts.

[0031] The tensioning assembly 9 includes a threaded rod 91 and round blocks 92 fixedly installed at the outer ends of the threaded rod 91. A roller 93 is movably installed in the middle of the outer surface of the threaded rod 91. Both ends of the threaded rod 91 are movably installed in the inner cavity of the through groove 712 and are fixed by threaded clamping with nuts. The thread position of the threaded rod 91 is set from both ends to the round blocks 92, and there is no thread in the middle of the threaded rod 91.

[0032] In this embodiment: After adjusting the setting position of the connecting shaft 81 in the cavity of the through groove 75, the short screw 83 is threaded and fixed to one side of the groove opening of the connecting groove 76 by using a nut. This completes the adjustment of the distance between the first pressure roller 74 and the second pressure roller 82, and thus completes the thickness adjustment of the soft polyethylene resin during winding. By passing the soft polyethylene resin through the lower end of the roller 93, the setting height of the roller 93 can be adjusted by adjusting the height of the threaded long rod 91 in the cavity of the through groove 712, thereby completing the tension adjustment of the winding of the soft polyethylene resin. The soft polyethylene resin is manually clamped and tilted onto the insulation pipe 3 by external clamps. The insulation pipe 3 rotates, and the output shaft of the electric push rod 6 drives the concave support block 71 to move along the winding direction of the insulation pipe 3, so that the soft polyethylene resin can be wound onto the insulation pipe 3.

[0033] Example 2: This example is an improvement on Example 1. For details, please refer to [link / reference]. Figure 3 A long groove 11 is provided in the middle of one side of the upper end of the base 1. Limiting grooves 12 are respectively provided in the middle of both sides of the inner wall of the long groove 11. The sliding block 73 is slidably installed in the inner cavity of the long groove 11, and the extension block 732 is slidably installed in the inner cavity of the limiting groove 12.

[0034] A right-angle block 711 is fixedly installed on both sides of one end of the outer surface of the concave support block 71, and a through groove 712 is opened in the middle of one side of the outer wall of the right-angle block 711.

[0035] A square magnetic groove 731 is provided in the middle of the upper end of the sliding block 73. Extension blocks 732 are fixedly installed in the middle of both sides of the outer wall of the sliding block 73. The magnetic blocks 72 and the square magnetic groove 731 are inserted and magnetically connected and fixed to complete the fixed installation of the concave support block 71 in the upper end of the sliding block 73.

[0036] In this embodiment: when the electric push rod 6 pushes the concave support block 71 to move, the insertion magnetic block 72, which is fixedly installed at the lower end of the concave support block 71, is magnetically fixed in the inner cavity of the square magnetic groove 731. The movement of the concave support block 71 can drive the sliding block 73 and the extension block 732 to slide along the long groove 11 and the limiting groove 12, thereby assisting the concave support block 71 in sliding guidance and improving the stability of the movement of the concave support block 71.

[0037] Working principle: After adjusting the position of the connecting shaft 81 in the cavity of the through groove 75, the short screw 83 is threaded and fixed to one side of the groove opening of the connecting groove 76 by using a nut. This allows for adjustment of the distance between the first pressure roller 74 and the second pressure roller 82, thus adjusting the thickness of the soft polyethylene resin during winding. By passing the soft polyethylene resin through the lower end of the roller 93, the height of the roller 93 can be adjusted by adjusting the height of the threaded rod 91 in the cavity of the through groove 712, thereby adjusting the tension of the soft polyethylene resin winding. The conveyor is manually clamped by external clamps. The soft polyethylene resin is spread at an angle on the insulation pipe 3. When the insulation pipe 3 rotates, the output shaft of the electric push rod 6 drives the concave support block 71 to move along the winding direction of the insulation pipe 3, so that the soft polyethylene resin can be wound on the insulation pipe 3. At the same time, when the electric push rod 6 pushes the concave support block 71 to move, the insertion magnetic block 72, which is fixedly installed at the lower end of the concave support block 71, is magnetically fixed in the inner cavity of the square magnetic groove 731. The movement of the concave support block 71 can drive the sliding block 73 and the extension block 732 to slide along the long groove 11 and the limiting groove 12, thereby assisting the concave support block 71 to slide and guide.
