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 inner wall of a pipeline. Background Art

[0002] As a key fluid control component, ball valves play an important role in many industrial applications due to their excellent sealing performance and fast operating response. The core component of this valve is a rotatable ball, which can quickly open and close the fluid through its 90-degree rotation, thereby accurately controlling the flow of fluid in the pipeline.

[0003] The pipeline equipped with a ball valve is a fluid transmission system that integrates the ball valve control function. Such a pipeline system can not only achieve stable and continuous transmission of fluids, but also can flexibly adjust the fluid flow and flow direction through the precise control of the ball valve.

[0004] The pipeline equipped with a ball valve is usually a separate section. When connecting other pipelines, glue needs to be applied on the inner wall of the ball valve pipeline to achieve the effect of sealing connection with other pipelines. The existing method of applying glue is mainly through manual glue application, which is very inefficient. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the utility model is to provide an automatic gluing device for the inner wall of a pipeline, which has the advantage of improving the gluing efficiency.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A device for automatically coating the inner wall of a pipeline with glue comprises a rotating chuck and a gluing mechanism relatively arranged on a workbench. The gluing mechanism comprises a linear driving component and a glue spraying tube located on the linear driving component. One end of the glue spraying tube is connected to a glue bucket filled with glue through a pump, and the other end faces the direction of the rotating chuck.

[0008] The advantages of this solution are at least that: the pipe is clamped on the rotating chuck, the rotating chuck will grab the ball valve pipe and start to rotate, during which the glue spray hose is moved to a position close to the inner wall of the ball valve pipe through a linear drive component, and then glue is sprayed from the glue spray hose to the inner wall of the ball valve pipe through a pump. As the rotating chuck drives the ball valve pipe to rotate, glue is continuously sprayed out from the glue spray hose, and the inner wall of the ball valve pipe can be coated with glue. There is no need for manual gluing, which improves the gluing efficiency.

[0009] The utility model is further configured as follows: a tube tongue with an arc-shaped cross section is extended from the outlet of the glue spraying tube.

[0010] The advantages of this solution are at least that the tube tongue has an arc-shaped cross-section rather than a circular cross-section of a glue spray hose. When the glue flows out of the glue spray hose outlet, the glue will be between the tube tongue and the inner wall of the ball valve pipe. At this time, the tube tongue plays a smearing role, smearing the glue on the inner wall of the ball valve pipe.

[0011] The utility model is further configured as follows: the linear drive member is provided with a mounting seat 1 and a mounting seat 2 located above the mounting seat 1;

[0012] The mounting seat 1 is provided with a clearance groove for the glue spraying hose to be inserted into, the glue spraying hose is inserted into the clearance groove and extends to the outside of the mounting seat 1 at the outlet end, the mounting seat 1 is provided with a spring sheet at the top opening of the clearance groove, and the movable end of the spring sheet is separated from the glue spraying hose;

[0013] The second mounting seat is provided with an air jet pipe, the outlet of which faces the position of the shrapnel below and is used to blow the shrapnel toward the glue spraying pipe.

[0014] The advantages of this solution are at least that the gas ejected from the jet pipe will bounce the active end of the shrapnel toward the glue spray hose, which can instantly squeeze the glue in the glue spray hose to the inner wall of the ball valve pipe on the one hand, and drive the glue spray hose to move downward a short distance, thereby adhering the tube tongue to the inner wall of the ball valve pipe, avoiding the phenomenon of "warping up" of the glue spray hose and ensuring that the tube tongue can apply glue to the inner wall of the ball valve pipe.

[0015] The utility model is further configured as follows: an air suction pipe is provided on the top of the second mounting seat located at the outlet end of the glue spraying tube, and the opening of the air suction pipe is close to the outlet end of the glue spraying tube.

[0016] The advantage of this solution is at least that the suction pipe can suck the outlet end of the glue spray hose upward, so that the end of the glue spray hose close to the tube tongue is lifted up to form a "tilted head" state, ensuring that the glue spray hose can enter the ball valve pipeline when moving toward the ball valve pipeline.

[0017] The utility model is further configured as follows: a slideway for adjusting the position of the air jet pipe is provided on the second mounting seat, and a locking member for locking the air jet pipe on the slideway is provided on the slideway.

[0018] The utility model is further configured as follows: a slideway for adjusting the position of the air intake pipe is provided on the second mounting seat, and a locking member for locking the air intake pipe on the slideway is provided on the slideway.

[0019] In summary, the utility model has at least the following advantages:

[0020] 1. By setting a rotating chuck and a gluing mechanism, the pipe is clamped on the rotating chuck, and the rotating chuck will grab the ball valve pipe and start to rotate. During this process, the glue spraying hose is moved to a position close to the inner wall of the ball valve pipe through a linear drive component, and then the glue is sprayed from the glue spraying hose to the inner wall of the ball valve pipe through a pump. As the rotating chuck drives the ball valve pipe to rotate, glue is continuously sprayed from the glue spraying hose, and the inner wall of the ball valve pipe can be glued. There is no need for manual gluing, which improves the gluing efficiency;

[0021] 2. By setting the tube tongue, the tube tongue plays the role of smearing, which makes it convenient to apply glue on the inner wall of the ball valve pipe;

[0022] 3. By setting the spring piece and the jet pipe, the gas ejected from the jet pipe will bounce the active end of the spring piece toward the glue spraying pipe. On the one hand, it can instantly squeeze the glue in the glue spraying pipe to the inner wall of the ball valve pipe, and on the other hand, it can drive the glue spraying pipe to move downward for a short distance, and then adhere the tube tongue to the inner wall of the ball valve pipe, avoiding the phenomenon of "warping" of the glue spraying pipe, and ensuring that the tube tongue can apply glue to the inner wall of the ball valve pipe;

[0023] 4. By setting up the suction pipe, the suction pipe can suck the outlet end of the spray hose upward, so that the end of the spray hose close to the tube tongue is lifted up to form a "tilted head" state, ensuring that the spray hose can enter the ball valve pipeline when moving toward the ball valve pipeline.

[0027] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0028] A device for automatically applying glue to the inner wall of a pipe, such as Figure 1As shown, it includes a rotary chuck 1 and a glue coating mechanism 2 relatively arranged on a workbench, and the glue coating mechanism 2 includes a linear drive 21 and a glue spraying tube 22 located on the linear drive 21. The linear drive 21 is composed of a motor, a screw connected to the motor key, and a slider threadedly connected to the screw and cooperating with the slide rail to move only linearly. In other embodiments, the linear drive 21 can also be a cylinder or an oil cylinder, and the outlet end of the glue spraying tube 22 is installed on the slider, and can move to the direction of the rotary chuck 1 along with the slider.

[0029] like Figure 1 and Figure 2 As shown, one end of the glue spraying tube 22 is connected to a glue bucket (not shown) filled with glue through a pump (not shown in the figure), and the other end is directed toward the rotating chuck 1. In some embodiments, a tube tongue 3 is provided extending from the outlet of the glue spraying tube 22. It is worth mentioning that the tube tongue 3 has an arc-shaped cross section, rather than a circular cross section of the glue spraying tube 22.

[0030] The ball valve pipe 8 is clamped on the rotating chuck 1, and the rotating chuck 1 will grab the ball valve pipe 8 and start to rotate. During this process, the glue spraying hose 22 is moved to a position close to the inner wall of the ball valve pipe 8 through the linear drive 21, and then the glue is sprayed from the glue spraying hose 22 to the inner wall of the ball valve pipe 8 through the pump. At this time, the glue will be between the tube tongue 3 and the inner wall of the ball valve pipe 8. As the rotating chuck 1 drives the ball valve pipe 8 to rotate, the tube tongue 3 plays a smearing role, and the inner wall of the ball valve pipe 8 can be coated with glue.

[0031] In order to ensure that the glue spray hose 22 can correctly enter the ball valve pipe 8 under the drive of the linear drive member 21, in some embodiments, a suction pipe 52 is provided at the top of the mounting seat 25 located at the outlet end of the glue spray hose 22, and the opening of the suction pipe 52 is close to the outlet end of the glue spray hose 22. When the glue spray hose 22 moves toward the ball valve pipe 8, the suction pipe 52 can suck the tube tongue 3 upward, so that one end of the glue spray hose 22 outlet is lifted to form a "tilted head" state, thereby ensuring that the glue spray hose 22 can smoothly enter the ball valve pipe 8.

[0032] In order to ensure that the outlet end of the glue spray hose 22 can be glued as close as possible to the inner wall of the ball valve pipe 8 after entering the ball valve pipe 8, in some embodiments, the linear drive member 21 is provided with a mounting seat 1 4 and a mounting seat 2 5 located above the mounting seat 1 4. The mounting seat 1 4 and the mounting seat 2 5 are relatively fixed and can be driven by the linear drive member 21 at the same time.

[0033] The mounting seat 1 4 is provided with a clearance groove 41 for the glue spraying tube 22 to be inserted into. The glue spraying tube 22 is partially inserted into the clearance groove 41, and the outlet end of the glue spraying tube 22 extends to the outside of the mounting seat 1 in the direction of the rotating chuck 1 and connects with the tube tongue 3. The mounting seat 1 4 is provided with a spring 42 at the top opening of the clearance groove 41. The movable end of the spring 42 is separated from the glue spraying tube 22. Under the action of external force, the movable end of the spring 42 can move toward the glue spraying tube 22. When there is no external force, the spring 42 will rebound and remain separated from the glue spraying tube 22.

[0034] The mounting seat 2 5 is provided with an air jet 51, the outlet of which faces the position of the spring sheet 42 below and is used to blow the spring sheet 42 toward the glue spraying tube 22. The gas ejected from the air jet 51 will bounce the movable end of the spring sheet 42 toward the glue spraying tube 22, which can instantly squeeze the glue in the glue spraying tube 22 to the inner wall of the ball valve pipe 8 on the one hand, and drive the glue spraying tube 22 to move downward a short distance on the other hand, so as to adhere the tube tongue 3 to the inner wall of the ball valve pipe 8, thereby avoiding the phenomenon of the glue spraying tube 22 "warping up" and ensuring that the tube tongue 3 can apply glue to the inner wall of the ball valve pipe 8.

[0035] It is worth mentioning that a slide 6 can be set on the mounting seat 2 5 for adjusting the position of the jet pipe 51 and / or the suction pipe 52, and the jet pipe 51 and / or the suction pipe 52 can be locked on the slide 6 through a locking member 7 such as a nut or a screw to facilitate the setting of the glue spray hose 22.

[0036] The working process and beneficial effects of the utility model are as follows: the pipeline is clamped on the rotating chuck 1, the rotating chuck 1 will grab the ball valve pipeline 8 and start to rotate, during which the glue spraying hose 22 is moved to a position close to the inner wall of the ball valve pipeline 8 through the linear drive member 21, and then the glue is sprayed from the glue spraying hose 22 to the inner wall of the ball valve pipeline 8 through the pump, at which time the glue will be between the tube tongue 3 and the inner wall of the ball valve pipeline 8, as the rotating chuck 1 drives the ball valve pipeline 8 to rotate, the tube tongue 3 plays a smearing role, and the inner wall of the ball valve pipeline 8 can be coated with glue, without manual gluing, thereby improving the gluing efficiency.

[0037] 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.
