Description

Technical Field

[0001] This utility model relates to the field of pipe processing technology, and in particular to an automatic wrapping device for the insulation layer of a cold-insulating pipe. Background Technology

[0002] Cold-insulated pipes are widely used in chemical, energy, and construction industries, and the quality of their insulation layer directly affects the pipe's insulation performance and service life. Traditional cold-insulated pipe insulation layer coating processes mainly rely on manual operation or simple mechanical assistance for installation.

[0003] A search revealed Chinese patent CN211363487U, which discloses an online wrapping device for thermal insulation pipes. The device includes: a shaping mechanism for forming a ring-shaped thermal insulation strip on the pipe surface; a shaping and heating mechanism for exposing two sides of the thermal insulation strip along its length and heating the exposed strip until its surface melts; and an adhesive and shaping mechanism for bonding and compacting the melted portions together. During manufacturing, the thermal insulation strip is first pre-shaped to adhere to the pipe surface. Then, the edges of the bonded strip are heated and melted, and the adhesive and shaping mechanism bonds the melted portions together. After cooling, the thermal insulation strip forms a tubular insulation layer on the pipe surface, thus forming an insulated pipe. Because this patented device can automatically form the insulation layer during pipe production, it avoids production difficulties when the inner hole of the insulation sleeve is too small, and poor insulation performance when the inner hole is too large, thus improving insulation performance without affecting production efficiency.

[0004] Based on the above search results and existing technologies, the following findings were made:

[0005] Existing insulation layer covering devices generally employ a fixed clamping structure, which is difficult to adapt to cold insulation pipes and insulation sleeves of different diameters. For example, when there is a slight deviation between the inner diameter of the insulation sleeve and the outer diameter of the cold pipe, the fixed clamp cannot dynamically adjust the sleeve opening size, leading to difficulties in docking. Specifically, traditional devices lack expandable adsorption components, making it impossible to expand the sleeve opening channel through elastic deformation. This makes it difficult to ensure the coaxiality of the sleeve and the cold pipe, easily causing jamming or even sleeve damage during installation. Furthermore, existing technologies typically rely on single mechanical pressure for covering, lacking precise control at the sleeve opening, resulting in gaps between the insulation layer and the cold pipe, affecting the insulation effect. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model proposes an automatic wrapping device for the insulation layer of a cold-insulating pipe. The cylinder two of the combined clamping mechanism drives the clamping baffle to grab the insulation layer sleeve. The retractable adsorption component cooperates with the arc-shaped telescopic plate through a vacuum generator to realize the adsorption and opening and closing control of the sleeve opening. The track mechanism cooperates with the cylinder one to drive the moving frame to move, and completes the automatic docking and installation of the insulation layer sleeve and the cold pipe body.

[0007] The technical solution to achieve the purpose of this utility model is: an automatic wrapping device for insulation layer of cold pipe, including a processing table, a horizontally corresponding cold pipe body and insulation layer sleeve are arranged on the front side of the processing table, a support mechanism is arranged at the bottom of the cold pipe body, and further includes;

[0008] A track mechanism, wherein the track mechanism is disposed on the inner side of the processing table;

[0009] The movable frame is slidably mounted on a track mechanism, and a cylinder is provided on the processing table to drive the movable frame to reciprocate back and forth along the track mechanism.

[0010] A combined clamping mechanism is provided on the side of the movable frame. The combined clamping mechanism includes a second cylinder provided on the upper and lower sides of the movable frame and two sets of clamping baffles driven to open and close by the second cylinder. The clamping baffles are used to grip one end of the insulation layer sleeve and connect it to the adjacent end of the cold pipe body for installation.

[0011] A retractable adsorption component is provided on two sets of clamping baffles to grip the outer wall of one end of the insulation layer sleeve, thereby controlling the opening of the insulation layer sleeve opening channel.

[0012] In some embodiments, corresponding slots are provided on adjacent sides of the two clamping baffles. The retractable adsorption assembly includes a vacuum adsorption unit and a telescopic unit. The vacuum adsorption unit includes an arc-shaped telescopic piece disposed at the opening of the corresponding slot. An array of adsorption holes is provided on the arc-shaped telescopic piece. A vacuum generator is installed on the outer side of the clamping baffle. The output end of the vacuum generator is connected to the arc-shaped telescopic piece through a flexible tube. The telescopic unit includes cylinder three installed at the far ends of the two clamping baffles. The output end of each cylinder three extends into the interior of the clamping baffle. A piston rod is connected to one side of the cylinder three extending into the interior of the clamping baffle. The other end of the piston rod is connected to the back of the arc-shaped telescopic piece.

[0013] In some embodiments, the arc-shaped telescopic piece is an internally hollow arc-shaped structure and is made of elastic rubber material.

[0014] In some embodiments, the outer connecting member of the clamping baffle has an L-shaped fixing block, with two sets of fixing blocks arranged symmetrically, and the ends of the fixing blocks that are far apart from each other are connected to the output shaft of the corresponding cylinder two.

[0015] In some embodiments, the support mechanism includes a support platform, a limiting rod on the top of the support platform, and a limiting sleeve. The limiting rod is an L-shaped pipe, and the horizontal end of the top of the limiting rod is inserted into the cold pipe body.

[0016] The limiting sleeve is welded and fixed to the support platform by a connecting rod, and the limiting sleeve is fitted on the outside of the cold pipe body.

[0017] In some embodiments, the track mechanism includes a chute formed inside the processing table and a movable block slidably disposed inside the chute. The bottom of cylinder one is fixed to the side opening of the chute by a support plate, and the output shaft of cylinder one extends into the chute and is fixed to the side of the corresponding movable block.

[0018] Compared with existing technologies, the significant advantages of this invention are:

[0019] Firstly, this utility model incorporates a track mechanism, a moving frame, a combined clamping mechanism, and a retractable adsorption assembly. The track mechanism, with its sliding groove and moving block working in conjunction with cylinder one, drives the moving frame to reciprocate stably along the track. Cylinder two of the combined clamping mechanism opens and closes the clamping baffle, gripping the insulation sleeve. The retractable adsorption assembly features a vacuum adsorption unit and a telescopic unit working together. The vacuum generator performs multi-point adsorption through the adsorption holes on the arc-shaped telescopic plate, and cylinder three controls the arc-shaped telescopic plate to open and close the opening of the insulation sleeve. These structures work together to achieve automatic and precise wrapping and installation of the insulation layer on the cold-insulating pipe, eliminating the need for manual operation, greatly improving wrapping efficiency and installation accuracy, and reducing labor costs and intensity.

[0020] Secondly, the arc-shaped telescopic plate of this utility model adopts an internally hollow arc-shaped structure and is made of elastic rubber material. The elastic material allows it to better fit the outer wall of the insulation layer sleeve under the drive of the cylinder, and the opening and closing are assisted by its own elastic restoring force. The internal hollow structure, together with the adsorption holes, allows the suction force of the vacuum generator to act more evenly, improves the adsorption stability, and ensures that the insulation layer sleeve will not easily fall off or shift during the installation process.

[0021] Thirdly, the L-shaped fixing block on the outer side of the clamping baffle of this utility model is connected to the output shaft of the second cylinder. The symmetrically arranged fixing blocks enable the second cylinder to stably drive the clamping baffle to open and close, ensuring the stability and reliability of the clamping baffle when gripping the insulation sleeve, and avoiding the insulation sleeve from falling off or the installation position from being deviated due to unstable gripping.

[0022] Fourthly, the support mechanism of this utility model includes a support platform, a limiting rod, and a limiting sleeve. The limiting rod is inserted into the inside of the cold pipe body, and the limiting sleeve is fitted on the outside of the cold pipe body. The cold pipe body is limited and fixed from both inside and outside, preventing the cold pipe body from shaking or shifting during the installation of the insulation layer sleeve. This further ensures the accuracy of the connection and installation between the cold pipe body and the insulation layer sleeve, and improves the overall installation quality.

[0023] This solution addresses the problems of existing cold insulation pipe insulation layer wrapping relying on manual operation, which is inefficient, inaccurate, labor-intensive, and costly. It also solves the problems of easy positional displacement and unstable gripping of the insulation layer sleeve and cold pipe during installation. Attached Figure Description

[0032] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0033] This utility model provides an improved automatic wrapping device for the insulation layer of a cold insulation pipe. The technical solution of this utility model is as follows:

[0034] Figures 1-5 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-5 The present invention will be further described below.

[0035] like Figures 1-5As shown, an automatic wrapping device for insulation layer of cold pipe includes a processing table 100. A horizontally corresponding cold pipe body 400 and insulation layer sleeve 500 are arranged on the front side of the processing table 100. A support mechanism is arranged at the bottom of the cold pipe body 400. The device also includes a track mechanism, a moving frame 700, a combined clamping mechanism, and a retractable adsorption component. The track mechanism is located inside the processing table 100; the movable frame 700 is slidably mounted on the track mechanism, and the processing table 100 is equipped with a cylinder 102 that drives the movable frame 700 to move back and forth along the track mechanism; the combined clamping mechanism is located on the side of the movable frame 700, including a cylinder 701 located on the upper and lower sides of the movable frame 700 and two sets of clamping baffles 600 driven by the cylinder 701 to open and close. The clamping baffles 600 are used to grip one end of the insulation sleeve 500 and connect it to the adjacent end of the cold pipe body 400; the retractable adsorption component is located on the two sets of clamping baffles 600 and is used to grip the outer wall of one end of the insulation sleeve 500 to control the opening of the insulation sleeve 500.

[0036] like Figure 1 , Figure 2 As shown, in one embodiment, the track mechanism includes a slide groove 101 formed inside the processing table 100 and a movable block 103 slidably disposed inside the slide groove 101. The bottom of cylinder 102 is fixed to the side opening of the slide groove 101 by a support plate, and the output shaft of cylinder 102 extends into the slide groove 101 and is fixed to the side of the corresponding movable block 103. With the arrangement of the slide groove 101, the movable block 103 and the cylinder 102, when the output shaft of cylinder 102 extends and retracts, it can drive the movable block 103 to slide in the slide groove 101, thereby causing the movable frame 700 to move back and forth along the track mechanism, realizing the stable movement of the movable frame 700, and providing a moving basis for the docking and installation of the insulation sleeve 500 and the cold pipe body 400.

[0037] like Figure 2 , Figure 3As shown, in one embodiment, the two clamping baffles 600 of the combined clamping mechanism have corresponding slots 601 on adjacent sides. The retractable adsorption assembly includes a vacuum adsorption unit and a telescopic unit. The vacuum adsorption unit includes an arc-shaped telescopic piece 801 disposed at the opening of the corresponding slot 601. The arc-shaped telescopic piece 801 has an array of adsorption holes 901. A vacuum generator 900 is installed on the outside of the clamping baffles 600. The output end of the vacuum generator 900 is connected to the arc-shaped telescopic piece 801 through a flexible tube. The telescopic unit includes cylinders 800 installed at the far ends of the two clamping baffles 600. The output end of each cylinder 800 extends into the clamping baffle 600, and a piston rod 802 is connected to one side of the cylinder 800 extending into the clamping baffle 600. The other end of the piston rod 802 is connected to the back of the arc-shaped telescopic piece 801. When the combined clamping mechanism grips one end of the insulation sleeve 500, cylinder 3 800 drives piston rod 802 to extend, causing arc-shaped telescopic plate 801 to adhere to the outer surface of the opening of the insulation sleeve 500. Vacuum generator 900 is connected to arc-shaped telescopic plate 801 through a hose, and uses adsorption holes 901 to perform multi-point adsorption on the outer wall surface of the outer opening of the insulation sleeve 500. Since the adsorption holes 901 are arrayed, the adsorption area is increased and the adsorption stability is improved. Subsequently, cylinder 3 800 controls piston rod 802 to retract, causing arc-shaped telescopic plate 801 to open and close up and down on the outer surface of the opening of the insulation sleeve 500. The elastic deformation of arc-shaped telescopic plate 801 expands the internal channel at the outer opening of the insulation sleeve 500, facilitating the docking and installation of the insulation sleeve 500 and the cold pipe body 400.

[0038] like Figure 3 As shown, in one embodiment, the arc-shaped telescopic piece 801 has an internally hollow arc-shaped structure and is made of elastic rubber. Due to its elasticity, it can deform under the action of the cylinder 800, better conforming to the outer wall of the insulation sleeve 500. Furthermore, during the stretching and contraction process, it can assist in the opening and closing of the insulation sleeve 500 through its own elastic restoring force. The internally hollow structure, combined with the adsorption hole 901, allows the suction force generated by the vacuum generator 900 to act more evenly on the insulation sleeve 500, further improving the adsorption effect.

[0039] like Figure 2 As shown, in one embodiment, the outer connecting member of the clamping baffle 600 has an L-shaped fixing block 602. Two sets of fixing blocks 602 are symmetrically arranged, with their far ends connected to the output shaft of the corresponding cylinder 701. The connection between the L-shaped fixing block 602 and the output shaft of the cylinder 701 ensures that the cylinder 701 can stably drive the clamping baffle 600 to open and close, guaranteeing the stability and reliability of the clamping baffle 600 in gripping the insulation sleeve 500.

[0040] like Figure 4 and Figure 5 As shown, in one embodiment, the support mechanism includes a support platform 200, a limiting rod 301 on the top of the support platform 200, and a limiting sleeve 302. The limiting rod 301 is an L-shaped pipe structure, and the horizontal end of the top of the limiting rod 301 is inserted into the interior of the cold pipe body 400. The limiting sleeve 302 is welded and fixed to the support platform 200 by a connecting rod, and the limiting sleeve 302 is fitted onto the outside of the cold pipe body 400. The limiting rod 301 is inserted into the interior of the cold pipe body 400, and the limiting sleeve 302 is fitted onto the outside of the cold pipe body 400, thus limiting and fixing the cold pipe body 400 from both the inside and outside directions, preventing the cold pipe body 400 from shaking or shifting during the installation of the insulation sleeve 500, and ensuring the accuracy of the docking and installation of the cold pipe body 400 and the insulation sleeve 500.

[0041] The working principle and usage process of this utility model are as follows: First, the cold pipe body 400 is placed on the support platform 200, so that the limiting rod 301 is inserted into the cold pipe body 400 and the limiting sleeve 302 is fitted on the outside of the cold pipe body 400, thus fixing the cold pipe body 400. At the same time, the insulation sleeve 500 is placed at the corresponding position in front of the processing table 100. Then, cylinder 2 701 drives the clamping baffle 600 to open, and the moving frame 700 moves along the track mechanism to a position above one end of the insulation sleeve 500 under the drive of cylinder 1 102. Then, cylinder 2 701 retracts, causing the clamping baffle 600 to close, gripping one end of the insulation sleeve 500. At this time, cylinder 3 800 drives the piston rod 802 to extend, causing the arc-shaped telescopic plate 801 to adhere to the outer surface of the opening of the insulation sleeve 500. The vacuum generator 900 is started, and the outer wall surface of the outer opening of the insulation sleeve 500 is adsorbed at multiple points through the adsorption hole 901. After adsorption stabilizes, cylinder 3 (800) controls piston rod 802 to retract, causing the arc-shaped telescopic plate 801 to open and close up and down on the outer surface of the opening of the insulation sleeve 500, expanding the internal channel at the outer end opening of the insulation sleeve 500. Then, cylinder 1 (102) restarts, moving the moving frame 700 towards the cold pipe body 400, fitting the insulation sleeve 500 onto the outer surface of the cold pipe body 400. After fitting, vacuum generator 900 stops working, the adsorption unit releases gas, cylinder 3 (800) drives piston rod 802 to extend, causing the arc-shaped telescopic plate 801 to retract into the clamping baffle 600. Cylinder 2 (701) drives clamping baffle 600 to open, and the moving frame 700 returns to its initial position under the action of cylinder 1 (102), awaiting the next round of fitting operation between the insulation sleeve 500 and the cold pipe body 400.

[0042] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
