Description

Technical Field

[0001] The utility model belongs to the field of glue coating devices, and more specifically relates to an automatic glue coating device for the outer wall of a pipeline. Background Art

[0002] As a key component for precise fluid control, ball valves enable efficient regulation of pipeline systems with their excellent sealing and quick operability. When a ball valve is integrated into an independent pipeline, this pipeline unit has the functions of fluid transmission and precise control of flow and direction. However, when connecting a pipeline equipped with a ball valve to other pipelines, it is crucial to ensure the sealing of the connection.

[0003] In this process, the traditional connection method involves applying glue to the outer wall of the ball valve pipe to form a closed connection with the adjacent pipe. However, this operation faces some practical challenges: on the one hand, manually applying glue evenly to the outer wall of the ball valve pipe is a time-consuming task, and it is difficult to improve work efficiency; on the other hand, the sticky nature of the glue itself easily causes it to adhere to the operator's hands during the construction process, thus affecting the operation speed. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the utility model is to provide an automatic gluing device for the outer wall of a pipeline, which has the advantage of increasing the gluing speed of the outer wall of the pipeline.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A device for automatically coating glue on the outer wall of a pipeline comprises a rotating chuck and a coating mechanism arranged on a machine platform, wherein the coating mechanism is located on the side of the rotating chuck; the coating mechanism comprises a linear drive mechanism and a glue outlet hose located on the linear drive mechanism, wherein the opening of the glue outlet hose faces the peripheral wall of the claws of the rotating chuck.

[0007] The advantages of this solution are at least that the ball valve pipe can be coaxially sleeved on the rotating chuck and driven to rotate by the rotating chuck, and then the glue discharge hose moves toward the peripheral side wall of the ball valve pipe through the linear drive mechanism until the outlet end of the glue discharge hose abuts against the upper half peripheral side wall of the ball valve pipe. At this time, the glue discharge hose is slightly tilted upward and leans against the upper half peripheral wall of the ball valve pipe. Glue is sprayed from the glue discharge hose and cooperates with the rotation of the ball valve pipe to spray glue on the peripheral wall of the glue discharge hose. The entire process does not require manual glue coating, which improves the glue coating speed of the outer wall of the pipe.

[0008] The utility model is further configured as follows: an extension tongue is provided at the outlet end of the glue discharge hose extending in the direction of the rotating chuck.

[0009] The advantage of this solution is at least that the inner wall of the extended tongue forms surface-to-surface contact with the peripheral wall of the ball valve pipe, so that the glue sprayed from the glue outlet hose can be smeared on the peripheral wall of the ball valve pipe.

[0010] The utility model is further configured as follows: a fixing frame is provided at the movable end of the linear drive mechanism, the glue outlet hose part is fixed on the fixing frame, and an air extraction pipe is provided above the outlet end of the glue outlet hose on the fixing frame.

[0011] The advantages of this solution are at least that: on the one hand, the vacuum pipe can suck up the outlet end of the glue discharge hose when the glue discharge hose is close to the ball valve pipe, so that the glue discharge hose is slightly tilted upward and leans against the upper half of the outer wall of the ball valve pipe to facilitate subsequent glue coating; on the other hand, the outlet end of the glue discharge hose can be sucked up when the glue discharge hose is outside the ball valve pipe to prevent the outlet end of the glue discharge hose from bouncing downward and causing the glue to be thrown out.

[0012] In summary, the utility model has at least the following advantages:

[0013] 1. By setting a glue outlet hose and limiting its opening to face the peripheral wall of the claw of the rotating chuck, during the glue coating process, the outlet end of the glue outlet hose will be slightly tilted upward and lean against the upper peripheral wall of the ball valve pipe. The glue is sprayed from the glue outlet hose and the ball valve pipe rotates to spray the glue on the peripheral wall of the glue outlet hose. The whole process does not require manual glue coating, which improves the glue coating speed of the outer wall of the pipe;

[0014] 2. By providing an extension tongue, the inner wall of the extension tongue forms a surface-to-surface contact with the peripheral wall of the ball valve pipe, so that the glue sprayed from the glue outlet hose can be applied to the peripheral wall of the ball valve pipe;

[0015] 3. By setting up an air suction pipe, the air suction pipe can suck up the outlet end of the glue discharge hose when the glue discharge hose approaches or moves away from the ball valve pipe, so that the outlet end of the glue discharge hose is tilted upward, so as to locate the position of the outlet end of the glue discharge hose and avoid the problem of glue being thrown out of the glue discharge hose.

[0019] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0020] A device for automatically applying glue to the outer wall of a pipeline, such as Figure 1 and Figure 2 As shown, it includes a rotating chuck 2 and a glue coating mechanism 3 arranged on a machine table 1. In some embodiments, the rotating chuck 2 can be a three-jaw chuck. The claws 21 of the three-jaw chuck can clamp the ball valve pipe 7 and rotate. The clamping and rotating functions of the rotating chuck 2 belong to the prior art and will not be repeated here.

[0021] The glue coating mechanism 3 is located on the side of the rotating chuck 2. In some embodiments, the glue coating mechanism 3 includes a linear drive mechanism 31 and a glue discharge hose 32 located on the linear drive mechanism 31, wherein the linear drive mechanism 31 can be a screw motor slider assembly or a cylinder, and the glue discharge hose 32 is partially fixed on the linear drive mechanism 31, and the linear drive mechanism 31 drives the glue discharge hose 32 to move linearly. The opening of the glue discharge hose 32 faces the peripheral wall of the claw 21 of the rotating chuck 2, so that the linear drive mechanism 31 can drive the glue discharge hose 32 to approach or move away from the side of the rotating chuck 2. In some preferred embodiments, the opening of the glue discharge hose 32 faces the rotating shaft perpendicular to the rotating chuck 2. It is worth mentioning that the outlet end of the glue discharge hose 32 should be slightly higher than the rotating shaft of the rotating chuck 2, so that when the outlet end of the glue discharge hose 32 approaches the ball valve pipe 7, it will be guided by the outer peripheral wall of the ball valve pipe 7 to tilt upward.

[0022] When applying glue to the end of the outer wall of the ball valve pipe 7, the ball valve pipe 7 is coaxially sleeved on the rotating chuck 2. The rotating chuck 2 drives the ball valve pipe 7 to rotate, and the outlet end of the glue discharge hose 32 is moved toward the peripheral wall of the ball valve pipe 7 through the linear drive mechanism 31 until the outlet end of the glue discharge hose 32 is against the upper half of the peripheral wall of the ball valve pipe 7. At this time, the glue discharge hose 32 is slightly tilted upward and leans against the upper half of the peripheral wall of the ball valve pipe 7. Glue is sprayed from the glue discharge hose 32 to cooperate with the rotation of the ball valve pipe 7, so that the glue can be sprayed on the outer peripheral wall of the glue discharge hose 32.

[0023] In order to make the glue more evenly applied to the outer wall of the ball valve pipe 7, in some embodiments, an extension tongue 4 is provided at the outlet end of the glue outlet hose 32 extending toward the rotating chuck 2. The extension tongue 4 is a sheet-shaped or arc-shaped structure, so that the inner wall of the extension tongue 4 forms a surface contact with the peripheral wall of the ball valve pipe 7, so that when the ball valve pipe 7 rotates, the glue sprayed from the glue outlet hose 32 can be applied to the peripheral wall of the ball valve pipe 7.

[0024] In some implementations, in order to facilitate the positioning of the glue discharge hose 32 and the separation of the glue discharge hose 32 from the ball valve pipe 7, a fixing frame 5 is provided on the movable end of the linear drive mechanism 31, and the part of the glue discharge hose 32 close to the outlet end is fixed on the fixing frame 5. The fixing frame 5 is provided with an air suction pipe 6 above the outlet end of the glue discharge hose 32. The air suction pipe 6 is driven by an air pump and can suck up the outlet end of the glue discharge hose 32, so that the outlet end of the glue discharge hose 32 is sucked up when the glue discharge hose 32 is close to the ball valve pipe 7, so that the glue discharge hose 32 is slightly tilted upward and leans against the upper half of the outer peripheral wall of the ball valve pipe 7 for subsequent glue coating. In addition, the outlet end of the glue discharge hose 32 can be sucked up when the glue discharge hose 32 is not in the ball valve pipe 7, so as to avoid the problem that the outlet end of the glue discharge hose 32 bounces downward and causes the glue to be thrown out.

[0025] The working process and beneficial effects of the utility model are as follows: the ball valve pipe 7 can be coaxially sleeved on the rotating chuck 2 and driven to rotate by the rotating chuck 2, and then the glue discharge hose 32 moves toward the peripheral side wall of the ball valve pipe 7 through the linear drive mechanism 31 until the outlet end of the glue discharge hose 32 abuts against the upper half peripheral side wall of the ball valve pipe 7. At this time, the glue discharge hose 32 is slightly tilted upward and leans against the upper half peripheral wall of the ball valve pipe 7. Glue is sprayed from the glue discharge hose 32 to cooperate with the rotation of the ball valve pipe 7, so that the glue can be sprayed on the peripheral wall of the glue discharge hose 32. The whole process does not require manual glue coating, which improves the glue coating speed of the outer wall of the pipe.

[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the design concept of the present invention should be included in the protection scope of the present invention.
