Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of sealant gun, specifically is a pneumatic sealant glue gun. BACKGROUND

[0002] In the industrial production and various building decoration fields, the application of the pneumatic sealant glue gun is extremely wide. The existing pneumatic sealant glue gun generally comprises a gun body and a nozzle connected to the connecting column of the gun body. In actual use, the glue extruded by the glue gun is usually in the form of a cylindrical strip structure, but in many cases, the extruded glue needs to be smoothed to meet the use requirements.

[0003] At present, the conventional method is to use a tool separately to perform the smoothing operation of the glue after the glue injection is completed. This operation method not only increases the complexity of the process, but also leads to low gluing efficiency, consumes more time and labor cost.

[0004] In order to solve the above problems, the application provides a pneumatic sealant glue gun with a detachable smoothing mechanism. The smoothing mechanism can complete the smoothing work while extruding the glue, greatly improving the gluing efficiency, and the detachable structure enables the smoothing operation to be conveniently detached when not needed, making the use more flexible and meeting the use requirements in different scenes.

[0021] With reference to the accompanying drawings, the technical solutions in the embodiments of the present application will be clearly and completely described below, obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work belong to the protection scope of the present application.

[0022] It should be noted that if the embodiments of the present application involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative positional relationship, movement condition, etc. between the components in a certain specific posture (as shown in the drawings), and if the specific posture changes, the directional indications will also change accordingly.

[0023] The utility model provides a kind of pneumatic sealant glue injection gun.

[0024] In the embodiment, with reference to Figures 1-2 The pneumatic sealant glue injection gun comprises a gun body 1, a nozzle 3 connected to the connecting column 2 of the gun body 1, and a smearing mechanism detachably connected to the nozzle for smearing the glue from the nozzle base.

[0025] The smearing mechanism comprises a smearing plate 4, a supporting rod 5 connected to one end of the smearing plate 4, and a sleeve ring 6 connected to one end of the supporting rod 5. The smearing plate 4 is provided with a nozzle port 7 that can be sleeved on the nozzle. The sleeve ring is sleeved and connected to the connecting column.

[0026] In the above technical solution, by providing a detachable smearing mechanism on the nozzle, the glue injection and smearing operations are synchronized, greatly improving the gluing efficiency. In actual use, there is no need to separately perform the smearing process after glue injection, saving time and labor costs. At the same time, the detachable structure design enables the user to conveniently detach the smearing mechanism when the smearing function is not needed, making the use of the glue injection gun more flexible, adapting to different working scenarios, and expanding the application range of the glue injection gun.

[0027] Specifically, the smearing plate is provided with a material blocking step 8 on both sides. The material blocking step 8 is provided with a smearing platform step 9 away from the nozzle port.

[0028] In the embodiment, the material blocking steps provided on both sides of the smearing plate can effectively block the overflow of glue during the glue injection process, can limit and drain the overflowing glue, avoid the random flow of glue, and ensure the accuracy of glue injection and the neatness of the working area. The smearing platform step away from the nozzle port side provides a standard reference surface for smearing the glue, so that the surface of the smeared glue is more flat and uniform, improving the smearing quality and aesthetic degree of the sealant, and further improving the overall quality of the product or engineering.

[0029] Specifically, the material blocking step and the troweling platform step form a "U" shaped structure with one end open.

[0030] In the embodiment, the material blocking step and the troweling platform step form a "U" shaped structure with one end open. This structure is beneficial in that, on the one hand, the gel can flow into the "U" shaped area naturally during the injection process, and is effectively restrained and guided, further enhancing the material blocking effect. On the other hand, the open design facilitates the cleaning of residual gel after the injection is completed, avoiding the gel from drying and sticking to the troweling mechanism, which affects the next use. At the same time, it also facilitates daily maintenance and maintenance work.

[0031] Specifically, the outer circle of the connecting column is provided with a plurality of wedge-shaped plates 10.

[0032] In the embodiment, the plurality of wedge-shaped plates provided at the outer circle of the connecting column can limit the sleeve ring on the connecting column when the sleeve ring is sleeved and connected on the connecting column, so that the connection of the sleeve ring and the connecting column is more stable and reliable, preventing the sleeve ring from loosening due to vibration and other reasons during the injection process. At the same time, the positioning by the wedge-shaped plates also facilitates the disassembly and assembly of the troweling mechanism.

[0033] Specifically, the troweling plate is provided with a direction indicating arrow 11 at the bottom.

[0034] In the embodiment, the direction indicating arrow is provided at the bottom of the troweling plate, which is used to correctly indicate the sliding direction of the extruded gel.

[0035] Note to all technical personnel: Although the utility model has been described according to the above specific embodiments, the utility model idea is not limited to this utility model, and any modification using the utility model idea will be included in the scope of protection of this patent.
