Description

Technical Field

[0001] This utility model belongs to the field of liquefied natural gas and relates to glue spraying technology in the production process of LNG ship insulation materials, specifically to a glue dispenser used in the production of LNG ship insulation materials. Background Technology

[0002] LNG (liquefied natural gas) membrane tanks are devices used to store liquefied natural gas and are commonly used on LNG carriers. Because LNG membrane tanks have very high requirements for sealing, stability, and insulation, their assembly is also very challenging and demanding. During the installation of LNG membrane tanks, many components are fixed together using adhesive, which necessitates the use of an adhesive spraying device.

[0003] Existing glue spraying devices such as Figure 1 As shown, the glue head structure used is a two-part design. This causes the glue outlet to wear easily, and different glue outlets have different wear conditions, which seriously affects the final glue dispensing uniformity.

[0004] To address the aforementioned problems, patent document CN219463880U discloses a glue spraying device for uniform glue application. This device replaces the existing bi-half glue outlet with a circular outlet. The circular outlet is not only less prone to wear, but the wear on each outlet is also roughly the same, seemingly solving the problem of uniform glue application. However, in practical applications, the following problems still exist: 1. Since the glue enters from the glue inlet pipe, the glue flow rate in the middle part of the sprayer pipe will inevitably be greater than that on both sides. This results in a larger glue output in the middle and a smaller output on both sides, making it difficult to achieve the ideal uniform glue output effect.

[0005] 2. The glue inlet pipe and the sealing gasket are welded together as an integrated structure, which makes cleaning the glue inlet pipe very difficult and can easily cause the glue outlet to become blocked due to glue accumulation. Summary of the Invention

[0006] Purpose of the invention: In order to solve the problems of insufficient glue uniformity and difficult cleaning in the existing technology, a glue dispenser for the production of LNG ship insulation boards is provided.

[0007] Technical Solution: To achieve the above objectives, this utility model provides an adhesive dispenser for the production of insulating sheets for LNG ships, including a cover plate and an adhesive inlet head disposed on the cover plate, as well as a dispenser and an adhesive spraying body. The dispenser is fitted onto the adhesive spraying body, and the cover plate is fitted onto the dispenser. The dispenser is provided with a dispensing groove, and a plurality of dispensing holes are arranged on the dispensing groove. The diameter of the dispensing holes on the dispensing groove gradually decreases from both sides to the middle. The adhesive spraying body is provided with a spraying groove, and a plurality of evenly arranged adhesive outlet holes are opened on the spraying groove.

[0008] Furthermore, the dispenser is bolted to the glue sprayer body, which facilitates the separation of the dispenser from the glue sprayer body and solves the problem of difficult cleaning inside the glue sprayer body.

[0009] Furthermore, the cover plate is bolted to the distributor.

[0010] Furthermore, the diameter of the dispensing holes on the dispensing groove is matched with the size of the glue inlet head, so that the glue output of each glue outlet on the final glue spraying body can be approximately the same, achieving the purpose of uniform glue output.

[0011] Furthermore, the cover plate has a glue inlet hole that matches the glue inlet head, and the glue inlet head is installed on the glue inlet hole.

[0012] Beneficial effects: Compared with the prior art, this utility model has the following advantages: 1. By designing a distributor on the glue spraying body, and with the size of the distribution holes on the distributor gradually decreasing from both sides to the middle, the glue distribution in the spraying tank on the glue spraying body can be made uniform, and the glue output of each dispensing hole can be basically consistent, thus truly achieving glue uniformity.

[0013] 2. The dispenser and the glue sprayer are detachably connected, allowing the glue sprayer to be opened, which solves the problem of difficult cleaning inside the glue sprayer and ensures the glue dispensing effect. Attached Figure Description

[0014] Figure 1 This is a schematic diagram of an existing glue spraying device; Figure 2 This is a schematic diagram of the assembled structure of this utility model; Figure 3 This is an exploded structural diagram of the present invention. Detailed Implementation

[0015] The present invention will be further illustrated below with reference to the accompanying drawings and specific embodiments. It should be understood that these embodiments are only for illustrating the present invention and are not intended to limit the scope of the present invention. After reading the present invention, any modifications of the present invention in various equivalent forms by those skilled in the art will fall within the scope defined by the appended claims.

[0016] like Figure 2 and Figure 3 As shown, this utility model provides an adhesive dispenser for the production of insulating sheets for LNG ships, including a cover plate 1, an inlet head 2, a dispenser 3, and an adhesive spraying body 4. The cover plate 1 has an inlet hole 5 that matches the inlet head 2. The inlet head 2 is threaded onto the inlet hole 5. The cover plate 1 and the dispenser 3 are respectively provided with several corresponding and matching first bolt holes 9 and second bolt holes 10. The cover plate 1 is bolted onto the dispenser 3 through the first bolt holes 9 and second bolt holes 10. The dispenser 3 is provided with a dispensing groove 11, on which six dispensing holes 6 are arranged. The diameter of the dispensing hole 6 gradually decreases from both sides to the middle. The glue spraying body 4 is provided with a spraying groove 7, and the spraying groove 7 has several evenly arranged glue outlet holes 8. The glue spraying body 4 is provided with a third bolt hole (not shown in the figure) that matches the second bolt hole 10 and the first bolt hole 9. The distributor 3 is connected to the glue spraying body 4 by bolts. The diameter of the dispensing hole 6 on the dispensing groove 11 matches the size of the glue inlet head 5, so that the glue distribution in the spraying groove 7 on the glue spraying body 4 can be uniform and the glue output of each glue outlet hole 8 can be basically consistent, thus truly achieving glue uniformity.

[0017] In this embodiment, when it is necessary to clean the inside of the glue spray body 4, simply remove the bolts to detach the distributor 3 from the glue spray body 4, thus opening the glue spray body 4. This makes it easier for workers to clean the spray tank 7 and the glue outlet 8, solving the problem of the difficulty in cleaning the inside of the glue spray body 4 and ensuring the glue dispensing effect.
