The horizontal drawing device includes a bracket, a push rod assembly, a forming assembly, and a bundling assembly. The push rod assembly is connected to the bracket. The push rod assembly includes a traveling unit and a push rod unit connected to the traveling unit. The push rod unit can push a quartz glass rod to advance along a first direction under the action of the traveling unit. The first direction is parallel to the horizontal direction. The forming assembly includes a tundish detachably connected to the bracket and a melting rod unit arranged below the tundish. The tundish and the push rod unit are oppositely arranged in the first direction, so that the quartz glass rod enters the tundish under the action of the push rod unit and is processed by the melting rod unit to form quartz glass fibers. The bundling assembly is arranged on one side of the forming assembly. The defect of this prior art is that there is no cooling structure specifically set for the tundish. Each time when the tundish needs to be repaired or replaced, the machine needs to be stopped and waited for the tundish to cool down before the operation can be carried out.

[0003] In order to solve the above technical problems, Chinese Patent Application Publication No. 215559890U, with a publication date of January 18, 2022, discloses a cooling device for replacing a glass fiber tundish, including a tank body.

The water spray pipes are connected with at least one water inlet pipe. The water inlet pipe penetrates through the tank body and is hermetically connected with the tank body. At least one drain port is arranged at the bottom of the tank body. Two corresponding handles are fixed on the outer side wall of the tank body. The defect of this prior art is that each time it is used, the cooling device needs to be manually installed to carry out the cooling operation. The assembly time plus the cooling time greatly increases the maintenance duration, and each installation is also extremely inconvenient.

[0004] In view of the above situation of the prior art, there is an urgent need for a technical solution that can solve the above defects. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide a forming assembly for a horizontal drawing device. A cooling structure is arranged inside the tundish structure. There is no need to stop the machine and re-assemble the cooling structure each time. After the cooling operation is completed, the cooling structure releases the interference so that the tundish structure can be lifted for the staff to maintain the tundish. It is convenient to use, shortens the maintenance duration, and improves the convenience of tundish maintenance.

[0006] The present invention provides a forming component for a horizontal wire drawing device, including a nozzle plate structure and a melt rod device. The melt rod device is arranged on one side below the nozzle plate structure, and further includes a cooling structure and a removal structure;

A vertical guide rail groove is opened along the height direction on an inner side wall of the outer mounting frame opposite to the convex platform, and a limiting convex column corresponding to be inserted into the vertical guide rail groove is arranged on a side surface of the inner positioning mounting frame opposite to the vertical guide rail groove. A push-pull cover plate is arranged on the upper surface of the outer mounting frame;

[0009] The removal structure includes a telescopic drive motor, a hinge seat, and an elastic hinge arm. The telescopic drive motor is fixedly installed at the bottom of the outer mounting frame. A hinge seat is installed at the power output end of the telescopic drive motor. One end of the elastic hinge arm is hinged to the hinge seat, and the other end of the elastic hinge arm is rotationally connected to the corresponding roller through a rotating shaft.

[0035] 3. The removal structure drives the cooling structure to be removed outside the inner positioning mounting bracket;

[0036] 4. Since the inner positioning mounting bracket is disengaged from the interference of the removal structure, the inner positioning mounting bracket rises under the elastic force of the spring, so that the upper surface of the leakage plate body is exposed outside the outer mounting bracket;

[0037] 5. After rotating the knob 32 by a predetermined angle, the limit stop piece 29 is urged to disengage from the interference with the upper surface of the leakage plate body 13;

[0038] 6. The operator pulls out the leakage plate body for maintenance;

[0039] 7. After completing the replacement or maintenance of the leakage plate body, insert the leakage plate body into the vertical installation slot, and after rotating the knob 32 by a predetermined angle, the limit stop piece 29 presses against the upper surface of the leakage plate body 13;

[0040] 8. Press down the inner positioning mounting bracket 16 into the outer mounting bracket 10;

[0041] 9. The removal structure drives the cooling structure to reset into the inner positioning mounting bracket and be in contact with the leakage plate body 13.

[0042] The present invention does not require re-assembling the cooling structure every time the machine stops. After the cooling operation is completed, the cooling structure releases the interference with the inner positioning mounting bracket 16 so that the leakage plate structure can extend out of the outer mounting bracket 10 for the staff to maintain the leakage plate body. It is convenient to use, shortens the maintenance time, and improves the convenience of leakage plate maintenance.

[0043] Furthermore, while the cooling structure releases the interference with the inner positioning mounting bracket 16, the leakage plate structure can also extend out of the outer mounting bracket 10. Only one telescopic drive motor 22 is used to complete two sets of actions, making the structure compact and saving components.

[0044] The above embodiments only represent one implementation manner of the present invention.
