Description

Technical Field

[0001] This utility model relates to the field of thermal insulation material installation equipment, specifically, to a self-adhesive pipe insulation material production device. Background Technology

[0002] With the increasing emphasis on energy efficiency in modern industry and construction, the insulation performance of pipes and their associated components has become increasingly important. Traditional insulation materials suffer from problems such as cumbersome construction, poor adhesion, and significant heat loss, which not only increases construction costs but also reduces insulation effectiveness. While various types of insulation materials are available, most require additional adhesives or mechanical fasteners during installation, increasing construction complexity and time. Therefore, developing a mobile device that can automatically apply adhesive to pipe insulation materials is particularly necessary.

[0003] Utility model patent CN222473347U discloses a continuous forming equipment for insulating felt tubes, including a conveying component, a glue spraying component, a mold component, and a cutting component. The conveying component includes a mounting base structure and a conveying structure, with the conveying structure connected to the mounting base structure. The glue spraying component is connected to the mounting base structure and faces the conveying component. The mold component is located at the discharge end of the conveying component and includes a frame and a mold structure, with the mold structure rotatably connected to the frame. The cutting component is correspondingly positioned to the mold component. This continuous forming equipment for insulating felt tubes effectively solves the problem of poor process continuity in the existing technology during the manufacturing of insulating felt tubes. However, the disclosed structure of this continuous forming equipment involves directly wrapping the soft felt onto the mold component, and it cannot produce a self-adhesive insulating material product for pipe insulation. Utility Model Content

[0004] In order to complete the application of the protective coating, the adhesion of the adhesive and the backing paper on a single set of equipment and realize the continuous production of thermal insulation materials, the technical solution adopted by this utility model is: a self-adhesive pipe insulation material production device, including a mobile chassis, on which an aerogel felt feeding mechanism, a backing paper feeding mechanism, a coating spraying mechanism, an adhesive application mechanism, a turning roller, an adhesive roller, and a receiving mechanism are respectively installed;

[0005] The paint spraying mechanism is located next to the aerogel felt dispensing mechanism and is used to spray paint onto one side of the aerogel felt dispensing mechanism.

[0006] The flipping roller is located on one side of the adhesive coating mechanism and is used to flip the aerogel felt after the coating is sprayed.

[0007] The adhesive application mechanism is located on one side of the flipping roller and is used to apply adhesive to the flipped aerogel felt.

[0008] The adhesive roller is positioned beside the adhesive application mechanism and is used to adhere the backing paper released from the backing paper feeding mechanism to the adhesive-coated side of the aerogel felt.

[0009] The take-up mechanism is located on one side of the adhesive roller and is used to take up the aerogel felt with the backing paper adhered to it.

[0010] Based on the above, in order to facilitate the rolling of the finished product after collection off the device, the collection mechanism includes a collection roller holder fixedly connected to the movable chassis, a collection roller and a magnetic synchronous wheel are rotatably arranged on the top of the collection roller holder, and the magnetic synchronous wheel is driven by a collection roller motor.

[0011] The receiving roller has a magnetic groove at one end, and the magnetic synchronous wheel has a magnetic boss for inserting into the magnetic groove. The receiving roller and the magnetic synchronous wheel are detachably connected by the magnetic groove and the magnetic boss.

[0012] Based on the above, in order to dry the coating sprayed on the aerogel felt in a timely manner and accelerate the solidification of the coating, the mobile chassis is also equipped with a heat preservation box. The heat preservation box is located between the coating spraying mechanism and the base paper feeding mechanism and is used to dry the coating sprayed on the aerogel felt.

[0013] Based on the above, the aerogel felt feeding mechanism includes a felt layer holder fixedly connected to the movable chassis, on which an aerogel felt roll is rotatably mounted.

[0014] Based on the above, the bottom paper feeding mechanism includes a bottom paper holder fixedly connected to the movable chassis, and a bottom paper roll is rotatably mounted on the bottom paper holder.

[0015] Based on the above, in order to facilitate the spraying of paint and to lay the aerogel felt flat to prevent wrinkles, the paint spraying mechanism includes a paint roller and a paint trough arranged side by side at the bottom of the receiving roller frame. The bottom of the paint trough has several paint spray holes, and a piston pump is connected to the outside of the paint trough to pump paint into the paint trough. The paint roller is driven by a paint roller motor. The paint roller is used to lay the aerogel felt flat before spraying paint.

[0016] Based on the above, in order to improve the structural compactness, the adhesive application mechanism, the flipping roller and the bonding roller are respectively located at the end of the heat preservation box away from the paint spraying mechanism.

[0017] Based on the above, the adhesive application mechanism includes an adhesive holder fixedly connected to the insulation box, an adhesive trough with holes at the bottom is rotatably provided on the adhesive holder, and a brush is provided at the bottom of the adhesive trough.

[0018] Based on the above, a telescopic rod is provided at the bottom of the mobile chassis away from the receiving mechanism. The telescopic rod is used to lift one end of the mobile chassis, so that the receiving roller collected by the receiving mechanism rolls off the mobile chassis.

[0019] Based on the above, a roller guide rail is also provided on one side of the top of the receiving roller holder, which is used to guide the rolling receiving roller.

[0020] This invention represents a substantial advancement over existing technologies. Specifically, the self-adhesive pipe insulation material production device provided by this invention simultaneously mounts an aerogel felt roll, a coating roller, a turning roller, an adhesive tank, a backing paper roll, and an adhesive roller on a mobile chassis. This allows the coating roller to apply coating to one side of the aerogel felt as a protective layer. Then, the turning roller flips the aerogel felt over, the adhesive tank applies adhesive to the other side, and finally, the adhesive roller joins the backing paper and aerogel felt together. Thus, the application of the protective coating layer, the adhesion of the adhesive, and the bonding of the backing paper are all completed in one set of equipment.

[0021] Therefore, this self-adhesive pipe insulation material production device can eliminate the need for additional adhesives and cumbersome mechanical fixing devices, as well as the step of applying a protective layer over the insulation layer in the traditional process. This not only simplifies the construction process and improves construction efficiency, but also enables automated production, improves production efficiency, and ensures that the quality and performance of each batch of materials are consistent, reducing human error.

[0022] Furthermore, the device can operate in a closed environment, which helps reduce environmental pollution, prevents workers from coming into contact with harmful substances in the coating, improves safety, avoids material contamination, and reduces waste.

[0023] Furthermore, by applying a coating layer to the aerogel felt, the coating layer can replace the traditional aluminum plate as a protective layer outside the insulation layer. This not only provides the protection of the traditional aluminum plate, but also reduces the burden on the pipe support structure. Attached Figure Description

[0050] Example 2

[0051] This embodiment provides a self-adhesive pipe insulation material production device. The main difference from Embodiment 1 is that in this embodiment, a telescopic rod 14 is provided at the bottom of the mobile chassis 1 away from the receiving mechanism. The telescopic rod 14 is used to lift one end of the mobile chassis 1 so that the receiving roller 7 collected by the receiving mechanism rolls off the receiving roller holder 17.

[0052] Example 3

[0053] This embodiment provides a self-adhesive pipe insulation material production device. The main difference from embodiment 2 is that in this embodiment, a roller guide rail 6 is also provided on the top side of the receiving roller holder 17. The roller guide rail 6 is used to guide the rolling receiving roller.

[0054] Specifically, the mobile preparation device for self-adhesive pipe insulation material provided by this utility model has the following usage steps:

[0055] After moving the device to the designated position, rotate the aerogel felt roll 5 and place it on the felt layer holder 4, place the bottom paper roll 12 on the bottom paper holder 13, place the take-up roller 7 on the take-up roller holder 17, and energize the magnetic synchronous wheel 8 to attract the magnetic protrusion 25, so that the magnetic protrusion 25 is inserted into the magnetic groove 20 on the take-up roller 7, thereby realizing the rotation and fixation of the take-up roller 7 and the magnetic synchronous wheel 8.

[0056] like Figure 6 As shown, in the initial state, following the path of the felt backing paper, the aerogel felt 16 and the backing paper 24 are manually moved around each roller according to the process, and then stretched onto the take-up roller 7. One end of the aerogel felt 16 and the backing paper 24 is fixed by the clamping seam 19 on the take-up roller 7.

[0057] Subsequently, the paint roller motor and the take-up roller motor drive the paint roller and take-up roller to move respectively. At the same time, the temperature of the insulation box is adjusted to 70℃ and the insulation time is set to 120 minutes.

[0058] As the paint roller 9 and the receiving roller 7 move the aerogel felt 16, the paint tank 10 and the paint roller 9 apply pressure to spray paint onto one side of the aerogel felt 16. The aerogel felt 16 is then conveyed to the insulation box 11 for heat preservation and curing.

[0059] After curing, the aerogel felt 16 is flipped by the flipping roller 15 and guided to the adhesive tank 21, where the adhesive in the adhesive tank 21 flows into the uncoated side of the aerogel felt 16.

[0060] Then, the backing paper 24 and the aerogel felt 16 coated with paint and adhesive pass together through the bonding roller 23, so that the backing paper adheres to the adhesive-coated side of the aerogel felt 16. Afterwards, the take-up roller 7 rotates to collect the adhered backing paper 24 and aerogel felt 16.

[0061] After preparation, the magnetic synchronous wheel 8 is de-energized, the magnetic boss 25 retracts to collect the material roller 7, and the telescopic rod 14 located at the rear end of the mobile chassis 1 extends to lift the mobile chassis 1, causing the material roller 7 to roll down along the roller guide rail 6.

[0062] The coating thickness, uniformly sprayed onto one side of the aerogel felt, can be 1mm to 2mm, and the temperature of the insulation box can be 50℃ to 200℃. The aerogel felt can be nano-silica aerogel insulation felt with a thickness of 5mm to 20mm. The adhesive can be one of acrylic glue, silicone glue, polyurethane glue, or epoxy resin glue. The backing paper can be one of glassine paper, kraft paper, polyester, coated paper, or polyethylene paper. The coating can be one of polyurethane coating, epoxy resin coating, ceramic coating, or rubber asphalt coating with waterproof and anti-corrosion functions.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
