Description

Technical Field

[0001] This utility model relates to the field of spraying machine technology, and more specifically, to a spraying machine for the outer wall of a bushing. Background Technology

[0002] A bushing outer wall spraying machine is a specialized piece of equipment used to apply coatings to the outer surface of bushings (common connecting or supporting components in machinery). This type of spraying machine is mainly used to improve the wear resistance, corrosion resistance, or other functional requirements of bushings, such as spraying anti-corrosion coatings, lubricating coatings, thermal spraying materials, etc.

[0003] However, during the spraying process, the coating distribution on the outer wall of the bushing is not uniform, resulting in some areas having coatings that are too thick or too thin. This not only affects the protective effect of the coating, but also makes it impossible to effectively collect and reuse excess paint, resulting in waste of resources and increased production costs. In addition, the spraying structure of the spraying machine cannot be automatically adjusted according to the specific size of the bushing during actual use, which seriously affects production efficiency.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a spraying machine for the outer wall of a bushing to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows: A spraying machine for the outer wall of a bushing includes a spraying frame, an auxiliary component on the spraying frame, a motor on the spraying frame, a placement frame at one end of the motor via a coupling, a collection hood inside the spraying frame, an adsorption tube passing through the bottom of the collection hood, an adsorption pump at one end of the adsorption tube, and a spraying component at one end of the adsorption pump.

[0007] Furthermore, in order to better adjust the height of the thermal spray gun according to the spraying situation, the spraying assembly includes multiple electric telescopic rods installed above the spraying frame. Each of the multiple electric telescopic rods has a fixing plate at one end. The thermal spray gun is mounted on one side of the fixing plate via an electric guide rail. Multiple delivery pipes are connected to the thermal spray gun. One end of each delivery pipe is connected to a delivery pump. One end of one delivery pump is connected to a spray cylinder. One side of the spray cylinder is located on one side of the spraying frame. The spray cylinder is connected to one end of the delivery pump and the adsorption pump. One end of the other delivery pump is connected to a gas tank.

[0008] Furthermore, in order to better agitate the powder placed in the spraying cylinder and prevent the powder from caking or accumulating and affecting the spraying effect, a second motor is installed at the bottom of the spraying cylinder. One end of the second motor passes through the spraying cylinder and is connected to a stirring rod. Multiple scraper blades are installed on the stirring rod, and one side of the scraper blades contacts the inner wall of the spraying cylinder.

[0009] Furthermore, in order to better improve the sealing performance of the spray gun, a sealing cap is hinged to the top of the spray gun, and multiple fixing buckles are provided on one side of the sealing cap, with one side of the fixing buckles connected to the surface of the spray gun.

[0010] Furthermore, to better improve the stability of the gas canister, the surface of the gas canister is equipped with a mounting bracket, with one side of the mounting bracket positioned on one side of the spraying rack.

[0011] Furthermore, in order to better assist in limiting the size of the bushing, the placement frame is provided with equally spaced auxiliary slots. The inner wall of the auxiliary slot is provided with multiple auxiliary springs. One end of the auxiliary spring is connected to the placement plate, and the outer periphery of the placement plate is located on the inner wall of the auxiliary slot.

[0012] Furthermore, in order to better collect, filter, and clean the sprayed powder, a filter screen is installed on the inner wall of the collection hood, a cleaning brush is installed above the filter screen, and an electric telescopic rod is installed on one side of the cleaning brush. One end of the electric telescopic rod is connected to one side of the inner wall of the collection hood.

[0013] The beneficial effects of this utility model are as follows: (1) The auxiliary components set in the spray frame can not only place and fix the bushings that need to be sprayed, but also effectively collect the excess paint generated during the spraying process, reducing resource waste and production costs. At the same time, the spraying components set in the auxiliary components can flexibly adjust the height of the thermal spray gun according to the size and shape of the bushing, ensuring that the spraying distance of the thermal spray gun is always kept at the best state, thereby achieving uniform spraying of various parts of the outer wall of the bushing, effectively avoiding the problem of excessively thick or thin coatings in some areas, and improving the uniformity and protective effect of the coating.

[0014] (2) By using the motor, agitator, and scraper installed in the spraying cylinder, the paint can be prevented from settling or condensing in the spraying cylinder, ensuring the uniformity and fluidity of the paint and improving the spraying quality. At the same time, the filter screen, cleaning brush, and electric telescopic rod installed in the collection hood can not only filter the collected spraying powder, but also prevent the filter screen from becoming clogged due to long-term use, ensuring the ventilation and collection efficiency of the collection hood, reducing the frequency and difficulty of manual cleaning, reducing the labor intensity of operators, and improving the maintenance efficiency of the equipment.

[0020] Example 2: like Figures 1-2 , Figure 5As shown, according to an embodiment of the present invention, a spraying machine for the outer wall of a bushing includes a spraying assembly 3 connected to one end of an adsorption pump 25. The spraying assembly 3 includes two electric telescopic rods 31 mounted above a spraying frame 1 for adjusting the height of a fixed plate 32. A fixed plate 32 is mounted at one end of each of the two electric telescopic rods 31 for mounting a thermal spraying gun 33. The thermal spraying gun 33 is mounted on one side of the fixed plate 32 via an electric guide rail. The thermal spraying gun 33 and the moving block of the electric guide rail are actually installed using screws or other detachable methods (not shown in the figure; this structure is conventional and therefore not described or drawn in detail). Two conveying pipes 34 are connected to the thermal spraying gun 33 for conveying gas and spraying powder. The thermal spraying gun 33 is used in practical applications... During use, a cooling pipe and wire (not shown in the figure) are also connected to circulate and cool the thermal spray gun 33 and to electrically connect the spray gun to the power supply through the wire. One end of each of the two delivery pipes 34 is connected to a delivery pump 35 for conveying gas and spray powder. The delivery pump 35 is a flexible hose. One end of one delivery pump 35 is connected to a spray cylinder 36 for holding the spray powder. One side of the spray cylinder 36 is set on one side of the spray frame 1. The spray cylinder 36 is connected to one end of the delivery pump 35 and the adsorption pump 25. One end of the other delivery pump 35 is connected to a gas tank 37 for storing the gas (compressed air, oxygen, acetylene or other fuel gas) required during the spraying process. The surface of the gas tank 37 is covered with a mounting bracket 9. One side of the mounting bracket 9 is set on one side of the spray frame 1. A motor 4 is installed below the spraying cylinder 36 to rotate the stirring rod 5. One end of the motor 4 passes through the spraying cylinder 36 and is connected to the stirring rod 5 to stir the spraying powder in the spraying cylinder 36, reducing the possibility of powder blockage or obstruction during spraying. Two scraper blades 6 are installed on the stirring rod 5 to scrape the spraying powder inside the spraying cylinder 36. One side of the scraper blade 6 contacts the inner wall of the spraying cylinder 36. A sealing cover 7 is hinged to the top of the spraying cylinder 36 to assist in shielding and sealing the spraying cylinder 36. Two fixing buckles 8 are installed on one side of the sealing cover 7 to improve the tightness between the sealing cover 7 and the spraying cylinder 36. One side of the fixing buckle 8 is connected to the surface of the spraying cylinder 36. Motor 2 4, wire, conveying pump 35, adsorption pump 25, electric telescopic rod 1 31, electric telescopic rod 2 14, motor 1 21, and electric guide rail are electrically connected to a controller (not shown in the figure) in actual use. The controller is a PLC (programmable logic controller) or a microcontroller. The specific working control program of the controller is written and set according to the actual situation, which is conducive to the precise control of the electrically connected electrical components.

Motor 2 4, wires, conveying pump 35, adsorption pump 25, electric telescopic rod 1 31, electric telescopic rod 2 14, motor 1 21, thermal spray gun 33, electric guide rail, and gas tank 37 are existing technologies and will not be described in detail. The specific model and specifications need to be selected and determined according to the actual specifications of the device.

[0021] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0022] In summary, with the help of the above-mentioned technical solution of this utility model, when in use, the operator pre-places the bushing on the placement frame 22, and the placement frame 22 adaptively fixes bushings of different sizes through the auxiliary spring 10 and the placement plate 11. After installation, the operator places one end of the placement frame 22 into the coupling. After installation, the motor 21 drives the placement frame 22 to rotate through the coupling, so that the outer wall of the bushing is evenly exposed to the spraying area. Meanwhile, the electric telescopic rod 31 of the spray frame 1 drives the fixed plate 32 to rise and fall, flexibly adjusting the height of the thermal spray gun 33 to ensure that the spraying distance is always in the optimal state. The thermal spray gun 33 moves laterally through the electric guide rail to achieve all-round spraying of the outer wall of the bushing. During spraying, the delivery pump 35 delivers the paint powder in the spray cylinder 36 and the compressed gas or gas in the gas tank 37 to the thermal spray gun 33 through the delivery pipe 34 to complete the spraying operation.

[0023] During spraying, motor 4 drives the stirring rod 5 to rotate and the scraper 6 to scrape off residual paint from the inner wall of the spray cylinder 36, preventing paint sedimentation or caking. The sealing cover 7 and fixing buckle 8 of the spray cylinder 36 ensure the airtightness of the spray cylinder 36, avoiding paint contamination or volatilization. During the spraying process, excess paint is adsorbed by the collection hood 23. The paint is then transported by the adsorption pump 25 through the adsorption pipe 24 to the spraying cylinder 36 for recycling. The filter screen 12 installed inside the collection hood 23 filters the recycled paint. The cleaning brush 13 installed on the filter screen 12 is driven by the electric telescopic rod 14 to clean the filter screen 12 regularly to prevent clogging and ensure ventilation and collection efficiency.
