Description

Technical Field

[0001] This utility model belongs to the field of thermal insulation pipe technology, specifically relating to a thermal insulation layer coating device for thermal insulation pipes. Background Technology

[0002] The basic structure of an insulated pipe typically consists of a working pipe, an insulation layer, and an outer protective pipe. The working pipe is responsible for transporting the medium, while the insulation layer's main function is to reduce heat loss and prevent heat from being transferred to the outside through the pipe, thereby improving energy efficiency and economic benefits. Adding an insulation layer to an insulated pipe requires a covering device. When using the covering device, adhesive is first applied to the outer wall of the insulated pipe, and then the semi-circular insulation layer is adhered to the adhesive-coated outer wall of the pipe.

[0003] The existing patent with publication number CN222080097U provides a device for covering the insulation layer of an insulation pipe. It is equipped with a movable plate, a glue roller, a fixed plate, a sealing plate, a limiting block, a glue tank, and a limiting groove. By placing the movable plate on the side of the glue roller, the thickness of the glue adsorbed by the glue roller can be controlled, which to a certain extent avoids the glue waste caused by excessive glue adhering to the glue roller. Later, the fixed plate can be moved up by the movable plate to clean up the impurities and residual glue that fall off the movable plate.

[0004] However, the above method can only clean the residual glue and impurities on the movable board after the glue application is completed. The glue residue on the movable board is prone to solidification during the glue application process, which increases the difficulty of later cleaning and leads to cleaning difficulties. Utility Model Content

[0005] To address the problems existing in the background technology, this utility model provides a thermal insulation layer covering device for thermal insulation pipes.

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

[0007] An insulation layer coating device for an insulated pipe includes two fixed seats, with a vacuum assembly and a liquid storage tank fixedly disposed between the two fixed seats. The liquid storage tank stores adhesive. Each fixed seat is equipped with both a lifting assembly and a power assembly for driving the lifting assembly to move. The lifting assembly is equipped with a clamping assembly that acts on the insulated pipe. The liquid storage tank is equipped with two fixed plates and a rotatable glue roller. The two fixed plates are symmetrically disposed on the inner walls of both sides of the liquid storage tank. Filter plates can be detachably installed in both fixed plates. Heating plates are fixedly disposed on the opposite sides of the two fixed plates. The heating plates are inclined, with the lower end of the heating plate fixedly connected to the fixed plate, and the higher end fixedly provided with a glue scraping part facing the glue roller and having the same curvature as the glue roller.

[0008] Furthermore, the fixed plate has limit grooves on both sides, and limit blocks are fixedly installed at both ends of the filter plate. The number of limit blocks and limit grooves are equal and correspond one-to-one. Each limit block is engaged with the corresponding limit groove.

[0009] Furthermore, the power assembly includes a second motor, and the second motor is fixedly mounted on two fixed seats, and a support plate is also fixedly provided on them. Each output shaft of the second motor is fixedly provided with a lead screw, and the other end of each lead screw is rotatably connected to the support plate on the fixed seat. Each of the two fixed seats is provided with a slider for limiting sliding, and each slider is threadedly connected to the lead screw on the fixed seat.

[0010] Furthermore, the lifting assembly includes a second cylinder, with a second cylinder fixedly installed on one side of each of the two sliders, and a movable seat fixedly installed on the telescopic shaft of each of the two second cylinders, with the two movable seats arranged symmetrically.

[0011] Furthermore, the clamping assembly includes a first cylinder, with the first cylinder fixedly mounted on one of the movable seats and the first motor fixedly mounted on the other movable seat; a clamping plate is rotatably mounted on the telescopic shaft of the first cylinder, and another clamping plate is fixedly mounted on the output shaft of the first motor, with the two clamping plates facing each other.

[0012] Furthermore, a placement plate is connected to the top of the air extraction assembly, and several air holes are formed on the placement plate.

[0013] This application has the following beneficial effects:

[0014] 1. In the process of gluing the insulation pipe, when there is a lot of glue left on the heating plate, the heating plate can heat the remaining glue, causing the solidified glue to melt and flow into the fixing plate under the tilting guidance of the heating plate. The glue flowing into the fixing plate will be filtered by the filter plate and then flow back into the storage tank. This not only improves the utilization rate of the glue, but also avoids the problem of glue being difficult to clean later due to solidification, resulting in better actual use effect.

[0015] 2. The filter plate and the fixed plate are detachable, and the limiting block and the limiting groove are slidably engaged to facilitate the disassembly of the filter plate, thereby making it easier to clean the impurities on the filter plate and further reducing the difficulty of subsequent cleaning.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0026] Example: Figures 1-6 As shown, the technical solution adopted by this utility model is as follows: a heat insulation layer covering device for a heat insulation pipe includes two fixed seats 1, and a vacuum component 2 and a liquid storage tank 5 are fixedly installed between the two fixed seats 1. The liquid storage tank 5 stores glue 20. The top of the vacuum component 2 is connected to a placement plate 3, and a plurality of air holes 4 are opened on the placement plate 3. The vacuum component 2 is existing technology and will not be described in detail in this solution. The vacuum component 2 generates a negative pressure on the top of the placement plate 3, thereby adsorbing and limiting the heat insulation layer.

[0027] The liquid storage tank 5 has two fixed plates 17 fixedly installed inside, and a roller cylinder 6 is rotatably installed inside. The two fixed plates 17 are symmetrically arranged on the inner walls of both sides of the liquid storage tank 5, and a filter plate 16 is detachably installed inside each fixed plate 17.

[0028] Each fixed plate 17 has a limiting groove 1703 on both sides, and each filter plate 16 has a limiting block 1601 fixedly installed at both ends. The number of limiting blocks 1601 and limiting grooves 1703 are equal and correspond one-to-one. Each limiting block 1601 is engaged with the corresponding limiting groove 1703. Through the engagement of the limiting blocks 1601 and the limiting grooves 1703, the filter plate 16 is detachably installed in the fixed plate 17.

[0029] Heating plates 1701 are fixedly mounted on the opposing sides of the two fixed plates 17. The heating plates 1701 are inclined, with the lower end of the heating plate 1701 fixedly connected to the fixed plate 17, and the higher end of the heating plate 1701 fixedly mounted with a scraper part 1702. The scraper part 1702 is close to the glue roller 6 and has the same curvature as the glue roller 6. The scraper part 1702 is used to scrape off a portion of the glue 20 that is too thick on the glue roller 6, so as to avoid excessive glue 20 on the glue roller 6 and causing waste.

[0030] In addition, the adhesive 20 in this solution can be made of acrylic adhesive. Acrylic adhesive itself has good fluidity, and heating by the heating plate 1701 can further improve the fluidity of adhesive 20, facilitating filtration by the filter plate 16. The filter plate 16 can be made of materials suitable for filtering viscous liquids, such as polypropylene and PTFE. PTFE filter screens have excellent non-stick properties and chemical stability. At the same time, PTFE material itself has extremely low surface energy, making it less wettable to substances with high surface tension, such as acrylic adhesive, thereby reducing the risk of clogging caused by surface tension.

[0031] The fixed base 1 is equipped with both a lifting component and a power component that drives the lifting component to move. The lifting component is equipped with a clamping component for acting on the insulation pipe.

[0032] The power assembly includes a second motor 14. One second motor 14 is fixedly mounted on each of the two fixed bases 1, and a support plate 13 is also fixedly mounted on each of them. Each second motor 14 has a lead screw 12 fixedly mounted on its output shaft, and the other end of each lead screw 12 is rotatably connected to the support plate 13 on its fixed base 1. Additionally, a slider 15 is slidably mounted on each of the two fixed bases 1, and each slider 15 is threadedly connected to the lead screw 12 on its fixed base 1.

[0033] The lifting assembly includes a second cylinder 9. A second cylinder 9 is fixedly installed on one side of each of the two sliders 15. A movable seat 7 is fixedly installed on the telescopic shaft of each of the two second cylinders 9. The two movable seats 7 are arranged symmetrically.

[0034] The clamping assembly includes a first cylinder 11, with the first cylinder 11 fixedly mounted on one of the movable seats 7 and the first motor 8 fixedly mounted on the other movable seat 7. The telescopic shaft of the first cylinder 11 is rotatably mounted with a clamping plate 10, and the output shaft of the first motor 8 is fixedly mounted with another clamping plate 10. The two clamping plates 10 are arranged facing each other.

[0035] Working principle: The device provides the necessary power to the electrical appliances inside the device through an external power supply. When in use, the insulation tube is placed between the two clamping plates 10, the first cylinder 11 is started, and the extension shaft of the first cylinder 11 drives the clamping plate 10 connected to it to move closer to the other clamping plate 10, thereby clamping and limiting the insulation tube.

[0036] Subsequently, the second cylinder 9 is activated, and its telescopic shaft causes the lower edge of the insulation tube to press against the upper edge of the roller 6. The first motor 8 is then activated, and its output shaft drives the clamping plate 10 connected to it to rotate, thereby causing the insulation tube to rotate. The insulation tube causes the other clamping plate 10 to rotate relative to the telescopic shaft of the first cylinder 11.

[0037] The rotation of the insulation tube causes the glue roller 6 to rotate, bringing its surface into contact with the glue 20. This allows the glue 20 to adhere to the surface of the roller 6, and the glue-coated roller 6 then contacts the insulation tube, thus applying glue to its surface. During rotation, the glue scraping part 1702 on the fixing plate 17 scrapes the glue from the surface of the roller 6, preventing excessive glue from adhering to its surface and thus avoiding excessive glue being carried out of the storage tank 5, thus preventing glue waste.

[0038] During the glue application process, some impurities and glue 20 will fall onto the heating plate 1701 and gradually solidify. When a significant amount of glue 20 solidifies on the heating plate 1701, the heating plate 1701 can heat the solidified glue 20, causing it to melt and flow into the fixing plate 17 under the inclined guidance of the heating plate 1701. The glue 20 flowing into the fixing plate 17 will be filtered through the filter plate 16 and then flow back into the storage tank 5. This not only improves the utilization rate of the glue 20 but also avoids the problem of the glue 20 being difficult to clean later due to solidification, resulting in better actual performance.

[0039] When it is necessary to clean the collected impurities, simply pull the filter plate 16 upward to release the locking block 1601 and the limiting groove 1703, and pull the filter plate 16 out, thereby realizing the centralized treatment and recycling of impurities.

[0040] After the adhesive is applied, the insulation layer is placed on the placement plate 3, and the suction assembly 2 is activated. Since the insulation layer is above the air vents 4, the suction assembly 2 can limit the insulation layer by using the air vents 4 when suctioning. At this time, the second cylinder 9 is activated. The telescopic shaft of the second cylinder 9 drives the insulation tube to move upward through the moving seat 7. At the same time, the second motor 14 is activated. The output end of the second motor 14 drives the lead screw 12 to rotate. The rotation of the lead screw 12 can drive the slider 15 to slide, thereby driving the insulation tube to move closer to the placement plate 3.

[0041] When the insulation pipe moves to the edge of the insulation layer, the second cylinder 9 is activated. The telescopic shaft of the second cylinder 9 drives the insulation pipe downward until the lower edge of the insulation pipe contacts the insulation layer. Then, the first motor 8 is activated, which drives the insulation pipe to rotate. The rotation of the insulation pipe, through the adhesive 20, wraps the insulation layer around the insulation pipe. The suction force generated by the suction component 2 is less than the adhesive force of the adhesive 20, thus achieving the wrapping of the insulation layer on the outside of the insulation pipe.

[0042] After the covering is completed, the clamping limit on the insulation tube is released by the telescopic shaft of the first cylinder 11.

[0043] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
