Description

Technical Field

[0001] This utility model relates to a pipe repair fabric composite machine, belonging to the field of pipe repair. Background Technology

[0002] In the field of pipeline repair, pipeline repair fabric is a key material for trenchless pipeline repair. It is formed by laminating pipe fabric with a hot-melt adhesive film. Existing pipeline repair fabric lamination equipment suffers from low lamination efficiency and unstable lamination quality, making it difficult to meet the growing demand for pipeline repair projects. Summary of the Invention

[0003] The purpose of this invention is to provide a pipe repair fabric laminating machine that can improve the lamination quality and production efficiency of pipe repair fabric.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: it includes an air-expanded shaft tube fabric unwinding mechanism for unwinding a flexible tube-shaped pipe fabric, a hot melt adhesive film unwinding roller for unwinding a hot melt adhesive film, a composite mechanism, a cooling mechanism, and an air-expanded shaft tube fabric winding mechanism arranged in sequence. The composite mechanism includes heating rollers located above and below the pipe fabric, respectively. The hot melt adhesive film unwinding roller includes hot melt adhesive film unwinding rollers located above and below the two heating rollers, respectively. After the two hot melt adhesive films are unwound, they are respectively composited on the upper and lower parts of the pipe fabric through the corresponding heating rollers to form a flexible tube-shaped pipe repair fabric.

[0005] Preferably, the air-expanded shaft tube unwinding mechanism includes a tube unwinding roller and a magnetic powder brake, with the magnetic powder brake acting on the tube unwinding roller. By setting the magnetic powder brake to control the unwinding tension of the tube unwinding roller, the tension of the pipe repair fabric during the lamination process can be effectively controlled, effectively avoiding problems such as roller slippage of the pipe fabric.

[0006] Preferably, the composite mechanism also includes a pair of transition rollers. After the pipe fabric is unwound, it passes through the pair of transition rollers. The pair of transition rollers play a transition role, making the pipe fabric before composite fit better without deformation or wrinkles.

[0007] Preferably, the cooling mechanism is an air-cooled cooling channel. The cold air rapidly cools and shapes the composite material, preventing deformation or poor adhesion due to excessive temperature.

[0008] Preferably, the air-shaft tube fabric take-up mechanism includes an air-shaft tube fabric take-up roller and a magnetic powder clutch, with the magnetic powder clutch acting on the air-shaft tube fabric take-up roller. The magnetic powder clutch is used to control the take-up speed of the air-shaft tube fabric take-up roller, ensuring that the unwinding and take-up are at the same speed.

[0009] Preferably, a pair of tension rollers are provided after the cooling mechanism, and the finished pipe repair cloth after the cooling mechanism passes through the pair of tension rollers. By adjusting the tension rollers, the tension of the release paper during the winding process can be precisely controlled to ensure stable tension and reduce the problem of release paper breakage caused by uneven tension.

[0010] Preferably, it also includes two air-expanded release paper take-up rollers to take up the release paper adhered to the corresponding hot melt adhesive film. These are used to collect the release paper that peels off the surface of the hot melt adhesive film.

[0011] With the above structure, this utility model, by setting up an air-expanded shaft tube unwinding mechanism, a hot melt adhesive film unwinding roller, a composite mechanism, a cooling mechanism, and an air-expanded shaft tube winding mechanism, has a compact overall equipment structure. All components work together to achieve continuous and efficient composite of pipeline repair cloth and hot melt adhesive film material, greatly improving composite quality and production efficiency, and meeting the needs of large-scale pipeline repair projects. Attached Figure Description

[0012] Figure 1 This is a schematic diagram of the present invention. Detailed Implementation

[0013] The present invention will be further described in detail below with reference to the embodiments given in the accompanying drawings.

[0014] See Figure 1 As shown, a pipe repair fabric laminating machine includes an air-expanded shaft tube fabric unwinding mechanism 1, a hot melt adhesive film unwinding roller 2, a laminating mechanism 3, a cooling mechanism 4, and an air-expanded shaft tube fabric rewinding mechanism 5.

[0015] See Figure 1As shown, the air-expansion shaft tube fabric unwinding mechanism 1 includes a tube fabric unwinding roller 11 and a magnetic powder brake 12. The tube fabric unwinding roller 11 is an air-expansion shaft design, and the hot melt adhesive film unwinding roller 2 also adopts an air-expansion shaft structure. In this embodiment, the air-expansion shaft is installed on the unwinding bracket, and the raw material roll of the pipe repair fabric is placed on the air-expansion shaft. By inflating the air-expansion shaft, the raw material roll is tightened, ensuring a tight connection between the raw material roll and the air-expansion shaft. The magnetic powder brake 12 is installed at one end of the air-expansion shaft and acts on the tube fabric unwinding roller 11. When unwinding begins, the tube fabric unwinding roller 11 starts to rotate under the drive of the motor, driving the raw material roll to unwind. The magnetic powder brake 12 adjusts the input current according to the preset tension value through the controller. When the fabric roll requires greater tension, the controller increases the current of the magnetic powder brake 12, which strengthens its internal magnetic field, increases the friction between the magnetic powders, and generates a larger resistance torque, hindering the rotation of the air-expansion shaft, thereby allowing the pipe repair fabric to maintain greater tension during the unwinding process. Conversely, when the fabric roll requires less tension, the controller reduces the current, the resistance torque of the magnetic powder brake 12 decreases, the rotational resistance of the air shaft decreases, and the unwinding tension decreases. Throughout the unwinding process, the magnetic powder brake 12 continuously adjusts the current in real time based on the actual tension information fed back by the tension sensor, thereby precisely controlling the resistance torque and working in conjunction with the air shaft to ensure that the duct fabric 20 is unwound with stable tension.

[0016] This embodiment uses two types of raw materials: the aforementioned pipe fabric 20 and the hot melt adhesive film 30. The lamination process involves bonding the hot melt adhesive film 30 to the upper and lower parts of the pipe fabric 20 to form a flexible tube structure. Therefore, the unwinding of the hot melt adhesive film 30 requires two unwinding rollers simultaneously. There are two hot melt adhesive film unwinding rollers 2, located above and below the two heating rollers 14 respectively. After unwinding, they are heated by the corresponding heating rollers 14 before being bonded to the upper and lower parts of the pipe fabric 20. Both hot melt adhesive film unwinding rollers 2 are passive rollers.

[0017] See Figure 1 As shown, the laminating mechanism 3 includes a transition roller 13 and a heating roller 14. The transition roller 13 and the heating roller 14 are used in pairs, located above and below the pipe fabric 20, respectively. In this embodiment, after the pipe fabric 20 is guided by the transition roller 13, the transition roller 13 guides the pipe fabric 20 between the two heating rollers 14 for lamination. The heating rollers 14 are turned on, and the temperature is adjusted to 100-120℃, so that the hot melt adhesive film 30 melts and fully laminates with the pipe fabric 20.

[0018] See Figure 1 As shown, a cooling mechanism 4 is provided after the composite mechanism 3. The cooling mechanism is an air-cooled channel in which air is blown. The cold air cools and shapes the composite material quickly. In this embodiment, the composite pipe repair cloth and hot melt adhesive film pass through the cooling mechanism 4, where the adhesive layer is quickly cooled and cured to form a stable composite structure.

[0019] Since both sets of hot melt adhesive films 30 in this embodiment are covered with release paper, the hot melt adhesive film 30 and the release paper need to be peeled off after lamination. See Figure 1 As shown, a pair of tension rollers 17 and a pair of air-shaft release paper take-up rollers 6 are provided between the air-shaft tube winding mechanism 5 and the cooling mechanism 4. The release paper is wound up by the corresponding air-shaft release paper take-up rollers 6 after passing through the tension rollers 17.

[0020] The final product, pipe repair cloth, is wound up by the air-shaft pipe cloth winding mechanism 5. The air-shaft pipe cloth winding mechanism 5 includes an air-shaft pipe cloth winding roller 15 and a magnetic powder clutch 16. The magnetic powder clutch 16 in the air-shaft pipe cloth winding mechanism 5 is installed at one end of the air-shaft. When winding the pipe cloth, the magnetic powder clutch 16 is used to control the rotation speed of the air-shaft pipe cloth winding roller 15 to avoid winding too fast or too slow.

[0021] See Figure 1 As shown, this utility model is equipped with an air-expanded shaft tube fabric unwinding mechanism 1, a hot melt adhesive film unwinding roller 2, a laminating mechanism 3, a cooling mechanism 4, and an air-expanded shaft tube fabric winding mechanism 5. The rolled pipe repair fabric raw material and hot melt adhesive film are respectively installed on the air-expanded shaft tube fabric unwinding mechanism 1 and the hot melt adhesive film unwinding roller 2 of the laminating machine. After the equipment is started, the unwinding mechanism will release the pipe repair fabric and hot melt adhesive film according to the set speed and tension. The transition roller 13 plays a guiding and tensioning role at this time, ensuring that the repair fabric and adhesive film can smoothly enter the next process and prevent problems such as deviation and loosening. Under the action of the heating roller 14, the hot melt adhesive film 30 is heated to a molten state and laminated with the pipe fabric 20. After being laminated, the pipe repair cloth is cooled and cured by the cooling mechanism 4 to form a stable composite structure. The cooled and shaped composite pipe repair cloth is neatly rolled up by the air-expansion shaft pipe cloth winding mechanism 5. At the same time, the release paper is also neatly rolled up by the air-expansion shaft release paper winding roller 6 under the action of the tension roller 17, so that the rolled product has a neat and compact appearance, which is convenient for subsequent storage and transportation.

[0022] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present utility model, and these all fall within the protection scope of the present utility model.
