Description

Technical Field

[0001] The present application belongs to the technical field of preparation of exhaust pipes for water heaters, and in particular to an exhaust pipe plug assembly device. Background Art

[0002] The smoke exhaust pipe is an important component of the water heater for discharging heat and smoke to the outside. Generally, during actual installation, the smoke exhaust pipe will be extended to the outside so that the smoke can be discharged directly to the outside. In order to prevent backflow of rain or strong wind, the smoke exhaust pipe is generally installed at an angle so that the end of the smoke exhaust pipe is tilted downward to greatly reduce the probability of backflow. At the same time, in order to maintain smooth exhaust and avoid strong wind backflow, an array of exhaust holes are generally set on the side wall at the end of the smoke exhaust pipe, and then a plug is installed at the end of the smoke exhaust pipe to achieve circumferential exhaust at the end, while avoiding direct convection backflow from the end. Figure 1 As shown, it is a schematic diagram of the exploded structure of the end 11 and the plug 12 of a smoke exhaust pipe. It can be seen that a plurality of groups of exhaust holes in a circular array are arranged around the end 11, and the plug 12 protrudes toward one end of the smoke exhaust pipe to form a conical guide portion, so that the exhaust smoke can be deflected at the protrusion and discharged to the side. In actual production, manual operation is generally used to complete the assembly of the plug 12 to the end 11, and then the plug 12 is sent to the welding environment to complete the installation, and finally the end 11 with the plug 12 installed is installed on the smoke exhaust pipe body. Since there is generally a certain interference fit between the plug 12 and the end 11, the operator will need a good level of proficiency when operating, so as to grasp the matching strength and matching distance, avoid abnormal deformation, and affect subsequent welding. Utility Model Content

[0003] In order to solve the above-mentioned deficiencies of the prior art, the present application provides a smoke exhaust pipe plug assembly device, which automatically assembles the plugs delivered in sequence to the ends of the smoke exhaust pipes delivered in sequence, thereby improving the matching efficiency and reducing the matching error, and has strong practicality.

[0018] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings, but the embodiments described in the utility model are only part of the embodiments of the utility model, rather than all the embodiments.

[0019] The present application provides a smoke exhaust pipe plug assembly device, which is used to Figure 1The plug 12 shown is assembled to the exhaust pipe end 11, and the specific device includes: Figure 2-Figure 3 The first conveying mechanism 21, the second conveying mechanism, the arc clamping plate 23, the guide cylinder 33, the lower pressing block 35, etc. are shown.

[0020] The first conveying mechanism 21 is used to convey the exhaust pipe end 11 to be assembled. The conveyed exhaust pipe end 11 is in an upright state and one end for assembly is facing upward. In the current posture, the upper end of the exhaust pipe end 11 is one end for assembly with the plug 12, and the other end is for assembly with the exhaust pipe body. The second conveying mechanism is arranged above the first conveying mechanism 21 and is used to convey the plug 12 to be assembled. According to the actual layout of the factory area, the conveying directions of the two can be set to the same direction or the opposite direction, as long as the positions at the ends match.

[0021] There is a pair of arc-shaped clamping plates 23, which are arranged at the end of the conveying direction of the first conveying mechanism 21, and are respectively located on both sides of the conveyed exhaust pipe end 11, and are movable and arranged in a direction perpendicular to the conveying direction of the first conveying mechanism 21. Specifically, they can be realized by connecting the movable ends of a horizontal cylinder 24 respectively, and are used to clamp the conveyed exhaust pipe end 11 from both sides. When the exhaust pipe end 11 conveyed at the front is about to reach the clamping position, the arc-shaped clamping plate 23 moves toward the middle to clamp the exhaust pipe end 11 in the final centering position, that is, the position for assembly. At this time, according to the situation, the conveying of the first conveying mechanism 21 can be suspended to facilitate the step-by-step operation.

[0022] The guide cylinder 33 is connected to the end of the second conveying mechanism and is located above the arc clamping plate 23. It is used to receive the transported plug 12 and guide the plug 12 to the upper end of the exhaust pipe end 11 that has been clamped by the arc clamping plate 23. The lower pressing block 35 is arranged above the guide cylinder 33 and is movable in the vertical direction. Specifically, it can be realized by connecting the movable end of a vertical cylinder 36. When the plug 12 falls into the upper end of the exhaust pipe end 11 through the guide cylinder 33, it is pressed down by the lower pressing block 35 to complete the assembly of the plug 12 on the exhaust pipe end 11.

[0023] Optionally, the first conveying mechanism 21 may use a conveyor belt for conveying. Preferably, in order to maintain a relatively straight arrangement of the smoke exhaust pipe ends 11 being conveyed, limit bars 22 may be provided on both sides of the first conveying mechanism 21, and the limit bars 22 may be fixed by other brackets.

[0024] Specifically, as described in the background technology, the plug 12 has a conical protrusion in order to cooperate with the exhaust holes circumferentially of the exhaust pipe end 11 to exhaust and avoid strong wind backflow. Specifically, the plug 12 includes an annular portion and a conical protrusion formed on the annular portion, and the outer diameter of the annular portion is greater than the maximum diameter of the conical protrusion. Based on this structure, the second transmission mechanism may include a pair of spaced guide bars 31, such as Figure 4As shown, the spacing of the guide bar 31 is greater than the maximum diameter of the conical protrusion and smaller than the outer diameter of the annular portion, so that the conical protrusion of the plug 12 is facing downward and hung on the guide bar 31 for transportation. The specific transportation can be pushed and transported in sequence by the pushing force from the rear side.

[0025] Along the conveying direction of the second conveying mechanism, the inner wall of the end of the guide bar 31 is concave outward to form an arc-shaped enlarged diameter section 32. The diameter of the arc-shaped enlarged diameter section 32 is larger than the diameter of the annular portion, so that the plug 12 can fall from between the arc-shaped enlarged diameter sections 32 when it is conveyed here. Because it is a conical protrusion, even if there is a certain position error after the plug 12 falls, it will not affect its cooperation with the upper end of the exhaust pipe end 11. Specifically, as Figure 2-Figure 4 As shown, the guide cylinder 33 is connected to the lower part of the arc-shaped enlarged diameter section 32 and is coaxially arranged with the arc-shaped enlarged diameter section 32. The inner diameter of the guide cylinder 33 is larger than the diameter of the annular portion, which is convenient for guiding the falling plug 12 so that it can fall relatively accurately into the upper end of the clamped smoke exhaust pipe end 11. On this basis, further, the upper part of the guide cylinder 33 has an avoidance hole 34, which is opened on the side of the guide cylinder 33 facing the direction of the plug 12.

[0026] Preferably, Figure 2 , Figure 4 As shown, the top end of the guide cylinder 33 extends upward to form a limit arc stop higher than the arc-shaped expansion section 32 , which is used to limit the plug 12 transported into the arc-shaped expansion section 32 .

[0027] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application.
