Description

Technical Field

[0001] This utility model relates to the field of centrifuge technology, specifically to the adhesive spraying structure of a rock wool centrifuge. Background Technology

[0002] In the rock wool production process, the rock wool melted in the cupola furnace is combined with the rock wool adhesive in the centrifuge by the action of four centrifugal rollers to form fibers. The uniformity of the adhesive spraying will affect the quality of the fibers, and thus affect the production quality of the rock wool.

[0003] In the Chinese Patent Document Database, patent CN211303459U discloses a spray adhesive structure for a rock wool centrifuge. By rotating the spray nozzle onto the centrifugal roller, it is easy to maintain and replace it. However, in actual use, the spray nozzle is prone to loosening under the high-speed rotation of the centrifugal roller. Summary of the Invention

[0004] The purpose of this invention is to provide a spray adhesive structure for a rock wool centrifuge to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rock wool centrifuge adhesive spraying structure, including a nozzle disposed at the center of the centrifugal roller and an adhesive spraying pipe disposed at the center of the centrifugal shaft. The adhesive spraying pipe is internally connected to the nozzle. The centrifugal roller is internally provided with a mounting base that matches the nozzle, and the nozzle is fixedly connected to the mounting base. A plurality of limiting mechanisms are provided on the outer side wall of one end of the nozzle. A sliding groove is provided radially on the outer peripheral wall of the mounting base. The limiting mechanism includes a limiting slider slidably disposed inside the sliding groove, a positioning post fixed on the limiting slider, and an elastic reset member that pushes the positioning post into the sliding groove. An annular groove for accommodating the insertion of the limiting slider is provided on the inner side wall of the mounting base.

[0006] Furthermore, a positioning plate is provided on the outer wall of the glue spray tube near the nozzle end, one end of the glue spray tube is inserted into the interior of the nozzle, and the positioning plate abuts against one end of the mounting base.

[0007] Furthermore, anti-vibration washers are provided on the contact surfaces of the positioning plate and the mounting base.

[0008] Furthermore, the inner side of the annular groove is provided with a flared section whose size gradually increases.

[0009] Furthermore, the nozzle and the mounting base are connected by threads.

[0010] Furthermore, a retaining ring is detachably installed on the outer wall of the nozzle, and a through hole is provided on the retaining ring to accommodate the positioning post extending to the outside of the slide groove. The dimensions of the positioning post and the through hole are both smaller than the dimensions of the limiting slider.

[0011] Furthermore, the end of the positioning post away from the limiting slider is provided with a rounded top.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] By setting up an installation base and a limiting mechanism, it is convenient to maintain and replace the nozzle. At the same time, when the nozzle rotates synchronously with the centrifugal roller, the positioning pin is thrown out and inserted into the annular groove under the action of centrifugal force, which restricts the axial movement of the nozzle and improves the stability of the nozzle installation.

[0014] By installing anti-vibration washers, the impact of vibrations from the centrifugal roller and centrifugal shaft during operation on the glue spraying hose is reduced, extending the service life of the glue spraying hose and reducing the occurrence of leaks. Attached Figure Description

[0022] Please see Figure 1-4This utility model provides an embodiment of a rock wool centrifuge adhesive spraying structure, including a nozzle 4 disposed at the center of a centrifugal roller 1 and an adhesive spraying pipe 3 disposed at the center of a centrifugal shaft 2. The nozzle 4 has several through holes. The centrifugal shaft 2 is fixed to the center of the centrifugal roller 1 to drive the centrifugal roller 1 to rotate. The adhesive spraying pipe 3 communicates with the interior of the nozzle 4. The interior of the centrifugal roller 1 is provided with a mounting base 5 that matches the nozzle 4, and the nozzle 4 is fixedly connected to the mounting base 5. In this embodiment, the nozzle 4 and the mounting base 5 are connected by threads, but this connection can also be made as needed. The nozzle 4 is bolted together. Several limiting mechanisms 6 are provided on the outer wall of one end of the nozzle 4. A groove 401 is provided radially on the outer peripheral wall of the mounting base 5. Each limiting mechanism 6 includes a limiting slider 601 slidably disposed inside the groove 401, a positioning post 602 fixed to the limiting slider 601, and an elastic reset member 603 that pushes the positioning post 602 into the groove 401. An annular groove 501 is provided on the inner wall of the mounting base 5 to accommodate the insertion of the limiting slider 601. The limiting slider 601 can move axially within the groove 401. The nozzle 4 slides back and forth. The positioning post 602 is located at the end of the limiting slider 601 near the opening of the slide groove 401. A retaining ring 8 is detachably installed on the outer wall of the nozzle 4. The retaining ring 8 has a through hole to accommodate the positioning post 602 extending to the outside of the slide groove 401. The dimensions of the positioning post 602 and the through hole are smaller than the dimensions of the limiting slider 601. The retaining ring 8 can be a circular arc-shaped metal structure with one end open. It is bolted to the nozzle 4. During assembly, the through hole is aligned with each positioning post 602 and then fixed. It is used to limit the limiting slider 601. For easy disassembly and assembly, the elastic reset component 603 can be a spring, which is sleeved on the outside of the positioning post 602. One end abuts against the limiting slider 601, and the other end abuts against the retaining ring 8. During operation, the positioning post 602 is thrown out by the centrifugal force and extends to the outside of the retaining ring 8, inserting into the inside of the annular groove 501, so as to prevent the nozzle 4 from moving in the axial direction of the centrifugal roller 1 and causing it to loosen. When the centrifugal roller 1 stops rotating, the elastic reset component 603 pushes the limiting slider 601 and the positioning post 602 to reset, without affecting the disassembly, assembly and maintenance of the nozzle 4.

[0023] Furthermore, the inner side of the annular groove 501 is provided with a gradually increasing flared section to facilitate the insertion of the positioning post 602 into the interior of the annular groove 501.

[0024] Furthermore, the end of the positioning post 602 away from the limiting slider 601 is provided with a rounded top 604, which also facilitates the insertion of the positioning post 602 into the interior of the annular groove 501;

[0025] A positioning plate 301 is provided on the outer wall of the spray tube 3 near the nozzle 4. One end of the spray tube 3 is inserted into the interior of the nozzle 4. A through hole matching the nozzle 4 is provided through the center of one end of the centrifugal roller 1. One end of the nozzle 4 is inserted into the interior of the mounting base 5, and its nozzle extends to the exterior of the centrifugal roller 1. A slot matching the spray tube 3 is provided on the nozzle 4 inside the centrifugal roller 1. The positioning plate 301 abuts against one end of the mounting base 5. An anti-vibration washer 7 is provided on the abutment surface of the positioning plate 301 and the mounting base 5 to reduce the impact of vibration of the centrifugal roller 1 and centrifugal shaft 2 during operation on the spray tube 3, extend the service life of the spray tube 3, and reduce the occurrence of leakage.

[0026] Working principle: During operation, the glue spray tube 3 supplies glue to the inside of the nozzle 4, and then sprays it out through the spray hole on the nozzle 4 to combine with the rock wool. During the rotation of the centrifugal roller 1 and the centrifugal shaft 2, the nozzle 4 is driven to rotate synchronously. The limit slider 601 and the positioning column 602 are thrown out under the action of centrifugal force. The elastic reset member 603 is in a compressed state. The elastic reset member 603 is inserted into the inside of the annular groove 501, which plays an axial upper limit role for the nozzle 4 and improves the stability of the nozzle 4.

[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
