Description

Technical Field

[0001] This application belongs to the field of UV-curable glass fiber hose production, and more specifically, it relates to a glue-filling device, a glue-filling process, and a UV-curable glass fiber hose using the above-mentioned glue-filling process. Background Technology

[0002] The UV-curable fiberglass hose consists of an outer membrane, a fiberglass cloth layer, and an inner membrane, from the outside to the inside. During the production process, resin glue needs to be injected between the outer membrane and the inner membrane to connect the inner membrane and the outer membrane and to ensure that the fiberglass cloth layer between the inner and outer membranes is completely impregnated.

[0003] Refer to Chinese Patent Publication No. CN110303703A, which discloses a glue-filling device and method for a glass fiber flexible tube with an inner membrane, and specifically discloses the following technical solution: The glue-filling device is a single asynchronous glue-filling method, which fills the gap between the outer membrane and the inner membrane on the lower and upper sides of the tube sequentially on the same production line. The process only requires the transmission mechanism to completely transport the tube once, greatly improving production efficiency, saving glue-filling time, and reducing production costs. The operating table is tilted upwards, and the first and second anti-flow smoothing mechanisms are arranged along the lower and upper sides of the conveying mechanism. This ensures that the injected resin glue flows back under gravity when filling the lower or upper side of the tube, thereby accelerating the glue-filling time. Meanwhile, the first anti-flow and smoothing mechanism can ensure that the resin glue on the lower side of the injection tube does not flow back and that the thickness of the resin glue on the lower side of the injection tube is uniform; the second anti-flow and smoothing mechanism can ensure that the resin glue on the upper side of the injection tube does not flow back and that the thickness of the resin glue on the upper side of the injection tube is uniform.

[0004] Referring to Chinese Patent Publication No. CN120816751A, which discloses a glue-filling device for UV-curable glass fiber tubing, the patent document further discloses the following technical content: a frame with a first pressure roller, a second pressure roller, and a third pressure roller, and a conveyor belt. A seat mounting plate is provided between the second pressure roller and the first pressure roller. The seat mounting plate is located on both sides of the frame and is slidably connected to the frame slide rails via seat slide rail seats. The frame slide rails are located on both sides of the frame. The seat slide rail seats are connected to seat adjustment cylinders via plates, and the seat adjustment cylinders are arranged along the conveying direction of the conveyor belt. Side rollers and top rollers are respectively installed on the seat mounting plate, with the side rollers located on both sides of the top roller. This application can achieve glue filling between the inner and outer membranes of UV-curable glass fiber tubing without tilting the conveyor device, allowing the glue between the outer and inner membranes to fully impregnate the glass fiber cloth layer, thereby improving the glue filling effect and quality.

[0005] Referring to Chinese Patent Publication No. CN120307676A, a glue-filling production line for UV-curable glass fiber hoses is disclosed, specifically revealing the following technical details: The conveyor frame has side rails with a track carriage attached to the frame. The frame has a stop-flow roller and a smoothing roller connected to a roller fine-tuning plate and a roller adjusting plate, respectively. The roller adjusting plate is rotatably connected to the frame via the frame base. The top of the roller adjusting plate has a plate linkage rod with a rod-driven block. The top of the rod-driven block slides within a pressure plate guide groove. The sliding pressure plate is fixedly connected to the pressure plate linkage plate. The sliding pressure plate is connected in the pressure plate guide groove. The pressure plate linkage plate slides relative to the central frame under the drive of a vertical adjustment motor. The central frame is located in the middle of the frame and fixedly connected to it. This application enables the adjustment of the stop-flow roller and the smoothing roller, improving the flexibility and stability of the device adjustment and meeting the production requirements of UV-curable glass fiber hoses.

[0006] As can be seen from the patent documents CN110303703A, CN120816751A, and CN120307676A mentioned above, in the prior art, the operation method for filling UV-curable glass fiber tubes with adhesive is mostly horizontal. The horizontal setting results in a long production line, which cannot make full use of space, and the quality of adhesive filling requires a relatively complex process to ensure.

After the opening at the top of the UV-curable glass fiber hose is closed, it is guided by the transition roller A (18) and the transition roller B (19) and sent into the top conveyor belt (21), and then sent out horizontally by the top conveyor belt (21). The transition roller adjuster (20) is used to adjust the position of the transition roller A (18) and the transition roller B (19) relative to the top conveyor belt (21) so that the excess glue inside can flow into the UV-curable glass fiber hose in the space formed by the glue-filling roller group (13) and the auxiliary glue-filling roller group (17).

9. A UV-curable glass fiber flexible tube, characterized in that, It is produced using the potting process described in claim 8.
