Description

Technical Field

[0001] This application belongs to the field of dispensing apparatus, and more specifically, relates to a dispensing apparatus for UV-curing glass fiber tubing. 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] See Chinese Patent Publication No. CN110303703A, which discloses a glue-filling device and method for a glass fiber flexible tube with an inner membrane, and further 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] The applicant believes that the first-stage glue-filling structure can be redesigned to achieve more stable glue-filling quality and efficiency in the first-stage glue-filling device, reduce the difficulty of the second-stage glue-filling, and improve the glue-filling quality and efficiency of the UV-curable glass fiber hose.

The pressure roller adjusting cylinder 4 is mounted on the horizontal frame of the first pressure roller seat 2. The telescopic end of the pressure roller adjusting cylinder 4 extends downward and is hinged to the hinge arm adjusting rod 5.

[0024] Based on the above embodiments, the following paragraphs will continue to describe in detail the technical features involved and the functions and roles of these technical features in this technical solution, so as to help those skilled in the art to fully understand the technical solution and reproduce it.

[0025] In this application, the frame 1 is provided with a first pressure roller 6 at the tail end. There is a gap between the first pressure roller 6 and the conveyor belt that allows for vacuuming but does not allow resin to flow through. When used as a second stage, the distance between the first pressure roller 6 and the conveyor belt 7 can be adjusted by adjusting the first pressure roller 6.

[0026] In this application, the second pressure roller 13 and the third pressure roller 14 are used to adjust the thickness of the adhesive in the UV-curable glass fiber hose after adhesive filling, so that the thickness of the adhesive in the UV-curable glass fiber hose is maintained within a set range. The second pressure roller 13 and the third pressure roller 14 can be adjusted and linked synchronously, which can further ensure the consistency of the adhesive thickness.

[0027] In this application, a movable triangularly arranged top roller 22 and two side rollers 12 are provided between the second pressure roller 13 and the first pressure roller 6. The triangularly arranged side rollers 12 and top roller 22 can form a space for accommodating resin adhesive between themselves and the second pressure roller 13. After the resin adhesive is poured in from one end of the opening of the UV-curable glass fiber hose, it can accumulate within the aforementioned space. As the UV-curable glass fiber hose moves forward with the conveyor belt 7, the resin adhesive is distributed within the UV-curable glass fiber hose, that is, distributed between the inner film, the glass fiber cloth, and the outer film.

[0028] In this application, the second pressure roller 13 and the third pressure roller 14 can adjust their distance relative to the conveyor belt 7 through the pressure roller linkage plate 15. This distance adjustment includes adjusting the height between them and the conveyor belt 7, which can adjust the thickness of the glue filling in the UV-curable glass fiber hose; it also includes adjusting the distance between the second pressure roller 13 and the third pressure roller 14, which can ensure the consistency of the glue filling thickness in the UV-curable glass fiber hose.

[0029] In this application, one end of the pressure roller linkage plate 15 is hinged to both ends of the lifting side plate 18, the lifting side plate 18 is fixed to both ends of the lifting horizontal connecting plate 19, and the lifting horizontal connecting plate 19 can move relative to the connecting plate adjustment frame 20 under the drive of the horizontal lifting cylinder 24, that is, it can move relative to the conveyor belt 7.

[0030] In this application, the lifting side plate 18 is also equipped with a double-headed hydraulic cylinder, which can be connected to the cylinder linkage plate 16 respectively. The cylinder linkage plate 16 slides along the strip hole of the pressure roller linkage plate 15 through its shaft. The strip hole of the pressure roller linkage plate 15 is arranged along the length direction of the pressure roller linkage plate 15. Driven by the roller linkage hydraulic cylinder 17, the extension end of the roller linkage hydraulic cylinder 17 can drive the cylinder linkage plate 16 to move. The shaft of the cylinder linkage plate 16 drives the pressure roller linkage plate 15 to move by sliding along the strip hole in the pressure roller linkage plate 15. This enables the opening or tightening of the pressure roller linkage plates 15 on both sides of the lifting side plate 18, and also enables the adjustment of the distance between the second pressure roller 13 and the third pressure roller 14 and the conveyor belt 7.

[0031] In this application, the top roller 22 can be raised and lowered along the mounting adjustment hole 23 under the drive of the top roller adjusting cylinder 10, so that its distance relative to the conveyor belt 7 can be adjusted. The telescopic end of the top roller adjusting cylinder 10 is rotatably connected to the shafts at both ends of the top roller 22 through the seat. The height adjustment of the top roller 22 can adapt to the adjustment of the amount of glue poured into the UV-curable glass fiber hose, adapting to different glue pouring amounts, thereby realizing the glue pouring amount according to the different lengths of UV-curable glass fiber hoses.

[0032] In this application, the second-stage structure, such as the inclined conveyor belt 7 and the configured roller structure, enables secondary glue filling, as described in the prior art. Alternatively, the structure described in this application can be used to achieve secondary glue filling. Since the first pressure roller 6, the second pressure roller 13, and the third pressure roller 14 in this application can all be adjusted relative to the conveyor belt 7, the structure described in this application can still be adapted to the second-stage glue filling, ensuring that the resin glue is evenly distributed between the inner film, the outer film, and the fiberglass cloth.

[0033] Finally, although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
