Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of spraying machines, in particular to an adjustable pipeline spraying machine. Background Art
[0002] A pipe sprayer is a machine designed to apply a protective or decorative coating to pipe surfaces. This type of equipment is used in a variety of industries, particularly the petroleum, chemical, water treatment, and construction industries, to extend the life of pipes, prevent corrosion, and enhance their appearance.
[0003] However, traditional pipe spraying equipment is typically designed for specific pipe diameters, with limited functionality and applicability. When working with pipes of varying diameters, these devices often require replacement equipment or cumbersome mechanical adjustments, which not only increases the complexity of the operation but also increases time and financial costs. Utility Model Content
[0004] In response to the above-mentioned problems, the present invention provides an adjustable pipe spraying machine, which effectively solves the problem that traditional pipe spraying equipment is difficult to handle pipes of different diameters.
[0005] The utility model adopts the following technical solution: an adjustable pipe sprayer, comprising a disc, one side of the disc being rotatably connected to a driven gear via a rotating shaft, an air motor being provided on the other side of the disc, one end of the air motor passing through the disc being connected to a driving gear, the driving gear being meshed with the driven gear, a spray head being provided on one side of the driven gear, a connecting rod fixing frame being provided on the other side of the disc, a screw being provided on one side of the connecting rod fixing frame, a nut being threadedly connected to the screw, a connecting rod mounting sleeve being slidably connected to the screw, three first connecting rods being provided on the connecting rod fixing frame, three second connecting rods being provided on the connecting rod mounting sleeve, corresponding second connecting rods being hingedly connected to corresponding first connecting rods, rollers being provided on one end of both the second connecting rod and the first connecting rod, and a handle being provided on one side of the nut.
[0006] Furthermore, the first connecting rod is rotatably connected to the connecting rod fixing bracket, and the second connecting rod is rotatably connected to the connecting rod mounting seat.
[0007] Furthermore, the outer surface of the handle is provided with an anti-slip texture.
[0008] Furthermore, the roller is made of wear-resistant rubber.
[0009] Furthermore, the first connecting rod, the second connecting rod, the connecting rod fixing bracket and the connecting rod mounting sleeve are all made of reinforced material.
[0010] The advantages of this utility model lie in that by rotating the handle to adjust the relative position of the nut and screw, the expansion or contraction of the first and second connecting rods can be flexibly adjusted, allowing the roller to expand outward or contract inward, thereby adapting to pipes of different diameters. This design enables the sprayer to operate in pipes of various sizes, increasing its flexibility and versatility. The pneumatic motor drives the meshing operation of the driving and driven gears, allowing the spray head to rotate stably and quickly, improving spraying efficiency. This power transmission method not only ensures spraying speed but also spraying quality, resulting in uniform coating of the inner wall and reducing waste of raw materials.

[0014] In order to help those skilled in the art better understand the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.
[0015] In the description of the present invention, it should be understood that the terms "longitudinal", "transverse", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.
[0016] See Figure 1-2As shown, an adjustable pipe sprayer includes a disc 1, one side of the disc 1 is rotatably connected to a driven gear 2 through a rotating shaft, and the other side of the disc 1 is provided with an air motor 3, one end of the air motor 3 passes through the disc 1 and is connected to a driving gear 4, the driving gear 4 is meshed with the driven gear 2, and a nozzle 5 is provided on one side of the driven gear 2, and the other side of the disc 1 is provided with a connecting rod fixing frame 6, one side of the connecting rod fixing frame 6 is provided with a screw rod 7, a nut 8 is threadedly connected to the screw rod 7, and a connecting rod mounting sleeve 9 is slidably connected to the screw 7, three first connecting rods 10 are provided on the connecting rod fixing frame 6, and three second connecting rods 11 are provided on the connecting rod mounting sleeve 9, and the corresponding second connecting rods 11 are hingedly connected to the corresponding first connecting rods 10, and the second connecting rod 11 and one end of the first connecting rod 10 are both provided with rollers 12, and a handle 13 is provided on one side of the nut 8.
[0017] The first connecting rod 10 is rotatably connected to the connecting rod fixing bracket 6, and the second connecting rod 11 is rotatably connected to the connecting rod mounting seat, so that the overall adjustment mechanism is more flexible and accurate when adjusting to suit different pipe diameters.
[0018] The outer surface of the handle 13 is provided with anti-slip texture to increase the grip stability.
[0019] The roller 12 is made of wear-resistant rubber to protect the pipe from being scratched.
[0020] The first connecting rod 10, the second connecting rod 11, the connecting rod fixing bracket 6 and the connecting rod mounting sleeve 9 are all made of reinforced materials, which improves the durability and load-bearing capacity of the entire machine.
[0021] Working Principle: Rotating the operating handle 13 rotates the nut 8, which is threadedly connected to the screw 7. This causes the nut 8 to move linearly along the screw 7 as it rotates, pushing the connecting rod mounting sleeve 9 to slide. This, in turn, causes the first and second connecting rods 10 and 11 to contract, causing the roller 12 to expand outward, thus accommodating different pipe diameters. Activating the pneumatic motor 3 rotates the driving gear 4, which meshes with the driven gear 2, driving the rotation of the driven gear 2. The driven gear 2 is directly connected to the spray head 5, so when the driven gear rotates, the spray head also rotates, achieving uniform spraying within the pipe.
