Description

Technical Field

[0001] This utility model relates to the field of spraying, and in particular to a spraying device for surface processing of wear-resistant parts. Background Technology

[0002] Wear-resistant pipes play a crucial role in industrial applications, especially in environments that require materials with high wear and corrosion resistance, such as mining, chemical, oil and gas extraction. Due to the harsh working environment, equipment often faces serious wear and corrosion problems. Therefore, spraying wear-resistant pipes to enhance their surface hardness, wear resistance and corrosion resistance has become a key measure to improve equipment service life and reduce maintenance costs.

[0003] However, existing spraying equipment usually sprays paint directly onto the surface of wear-resistant pipes. A large amount of paint fails to adhere effectively to the surface of the wear-resistant pipes and instead escapes into the air in the form of paint mist, resulting in a large amount of paint waste. This not only increases production costs but also reduces the economic efficiency and environmental friendliness of the spraying operation. Utility Model Content

[0004] In order to overcome the shortcomings of existing spraying equipment that usually sprays paint directly onto the surface of wear-resistant pipes, resulting in a large amount of paint failing to adhere effectively to the surface of the wear-resistant pipes and instead dissipating into the air in the form of paint mist, leading to a large amount of paint waste, this utility model provides a spraying device for surface processing of wear-resistant parts.

[0005] Technical Solution: A surface coating device for wear-resistant parts, comprising a housing, a spray pipe, and fixing components; the housing is fixedly connected to the spray pipe; the housing is connected to two fixing components, which are used to fix the wear-resistant pipe and drive it to rotate; it also includes rotating rods, winding rods, a motor, a discharge pipe, connecting belts, and a recycling membrane; the housing is connected to four rotating rods; the housing is rotatably connected to two winding rods; the housing is fixedly connected to a motor matching the number of winding rods, and the output shaft of each motor is fixedly connected to the corresponding winding rod; the housing is connected to and fixedly connected to the discharge pipe; the discharge pipe has two slots; the front winding rod winds up and is fixedly connected to two connecting belts distributed to the left, and all connecting belts are fixedly connected to the rear connecting belt, and each connecting belt is in contact with the housing, each connecting belt is in contact with all rotating rods, and each connecting belt is slidably connected to all slots; the front winding rod winds up and is fixedly connected to a recycling membrane for covering the spray pipe and the wear-resistant pipe, and the recycling membrane is fixedly connected to all connecting belts.

[0006] To further explain, the fixed assembly includes a turntable, a sliding plate, a fixed plate, an electric push rod, and a power unit; the turntable is rotatably connected to the housing; the sliding plate is slidably connected to the turntable; the fixed plate is fixedly connected to the sliding plate; at least one electric push rod is fixedly connected to the turntable, and the telescopic part of the electric push rod is fixedly connected to the sliding plate; the housing is connected to a power unit for driving the turntable and its connected parts to rotate, and the power unit is connected to the turntable.

[0007] To further explain, the power unit includes a second motor, a gear, and a gear ring; the second motor is fixedly connected to the housing; the output shaft of the second motor is fixedly connected to the gear; the turntable is fixedly connected to the gear ring, and the gear ring meshes with the gear.

[0008] Further explanation includes the presence of scraper strips; scraper strips are also fixedly attached to the housing.

[0009] To further explain, it also includes air ducts; at least one air duct is fixedly connected to the casing.

[0010] Further explanation: It also includes electric sliders, mounting plates, limiting rods, and annular limiting plates; electric sliders matching the number of rotating rods are slidably connected to the left and right sides of the housing, and each electric slider is rotatably connected to the corresponding rotating rod; each electric slider is fixedly connected to a mounting plate; each left mounting plate is fixedly connected to a limiting rod, and each limiting rod is fixedly connected to the corresponding right mounting plate, and each limiting rod is in contact with all connecting strips; two annular limiting plates are fixedly connected to the left and right sides of the housing.

[0011] The beneficial effects are as follows: by covering the spray pipe and wear-resistant pipe with a recycling membrane, the escaping paint mist adheres to and condenses on the surface of the recycling membrane, and then moves along the surface of the recycling membrane towards the discharge pipe. Finally, it enters the external recycling device for storage through the discharge pipe. In this way, the escaping paint is recycled to reduce paint waste. This avoids the problem that existing spraying equipment usually sprays paint directly onto the surface of the wear-resistant pipe, and a large amount of paint fails to adhere effectively to the surface of the wear-resistant pipe, but instead escapes into the air in the form of paint mist, resulting in a large amount of paint waste.

[0012] The paint adhering to the surface of the recycling membrane is scraped off by a scraper, and the scraped paint falls into the discharge pipe, which further improves the paint recycling efficiency and ensures the cleanliness of the recycling membrane, making it easier to use the recycling membrane next time.

[0013] By adding air ducts, an external air pump blows air into the inside of the recycling membrane through the air ducts, so that the paint mist remaining on the inside of the recycling membrane is blown into the external recycling device for storage through the discharge pipe, thus avoiding the problem of a small amount of unrecovered paint mist remaining on the inside of the recycling membrane.

Detailed Implementation

[0021] The preferred technical solution of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] Example: A spraying device for surface processing of wear-resistant parts, such as... Figures 1-6 As shown, the device includes a housing 1, a spray pipe 2, and fixing components. The housing 1 is equipped with a PLC control system for controlling all electrically driven parts of the device.

[0023] It also includes a rotating rod 3, a winding rod 4, a motor 5, a discharge pipe 6, connecting belts 7, and a recycling membrane 8; the housing 1 is connected to four rotating rods 3 arranged in a rectangular pattern; the housing 1 is rotatably connected to two winding rods 4 arranged in a front-to-back pattern; the housing 1 is bolted to two motors 5, and the output shaft of each motor 5 is fixedly connected to the corresponding winding rod 4; the housing 1 is connected to and fixedly connected to the discharge pipe 6, and the discharge pipe 6 is connected to an external device for recycling spilled paint; the discharge pipe 6 has two sliding grooves 601 arranged in a front-to-back pattern; the front winding rod 4 winds up and is fixedly connected to two connecting belts 7 arranged to the left, and all connecting belts 7 are fixedly connected to the rear connecting belt 7, and each connecting belt 7 is in contact with the housing 1, and each connecting belt 7 is in contact with all rotating rods 3, and each connecting belt 7 is slidably connected to all sliding grooves 601; the front winding rod 4 winds up and is fixedly connected to the recycling membrane 8, and the recycling membrane 8 is fixedly connected to all connecting belts 7.

[0024] The fixed assembly includes a turntable 111, a sliding plate 112, a fixed plate 113, electric push rods 114, and a power unit; the turntable 111 is rotatably connected to the housing 1; the sliding plate 112 is slidably connected to the turntable 111; the fixed plate 113 for fixing the wear-resistant tube is fixedly connected to the sliding plate 112; the turntable 111 is bolted to two electric push rods 114 distributed vertically, and the telescopic parts of all electric push rods 114 are fixedly connected to the sliding plate 112; the housing 1 is connected to the power unit, and the power unit is connected to the turntable 111.

[0025] The power unit includes a second motor 121, a gear 122 and a gear ring 123; the housing 1 is bolted to the second motor 121; the output shaft of the second motor 121 is fixedly connected to the gear 122; the turntable 111 is fixedly connected to the gear ring 123, and the gear ring 123 meshes with the gear 122.

[0026] It also includes a scraper 9; the housing 1 is fixed with a scraper 9 for scraping off the paint adhering to the recycling membrane 8.

[0027] It also includes air ducts 10; the housing 1 is fixedly connected to two air ducts 10 distributed in a front-to-back manner, and all air ducts 10 are connected to an external air pump.

[0028] It also includes an electric slider 131, a mounting plate 132, a limiting rod 133, and an annular limiting plate 134; four rectangularly distributed electric sliders 131 are slidably connected to the left and right sides of the housing 1, and each electric slider 131 is rotatably connected to the corresponding rotating rod 3; each electric slider 131 is fixedly connected to a mounting plate 132; each left mounting plate 132 is fixedly connected to a limiting rod 133, and each limiting rod 133 is fixedly connected to the corresponding right mounting plate 132, and each limiting rod 133 is in contact with all connecting strips 7; two annular limiting plates 134 distributed front to back are fixedly connected to the left and right sides of the housing 1.

[0029] It should be noted in advance that all electrically driven components of this device are controlled by a PLC control system installed in the housing 1.

[0030] During spraying, the operator first manually rotates the handle on door 101 to open the machine casing 1. Then, the wear-resistant tube is placed horizontally between the two fixed plates 113. Next, the extension part of the electric push rod 114 is controlled to push the corresponding sliding plate 112 and fixed plate 113 towards the wear-resistant tube, so that the fixed plate 113 is inserted into the wear-resistant tube and the wear-resistant tube is fixed under the restriction of the two fixed plates 113. Then, the operator manually rotates the handle on door 101 to close the machine casing 1, thereby completing the assembly of the wear-resistant tube.

[0031] After assembly, the output shaft of motor 121 is controlled to drive the fixed plate 113 to rotate sequentially through the corresponding gear 122, gear ring 123, turntable 111 and sliding plate 112. The fixed plate 113 drives the wear-resistant tube to rotate. During this process, the external conveying device is controlled to convey the paint to the spraying pipe 2, so that the spraying pipe 2 atomizes the paint and sprays it evenly onto the surface of the wear-resistant tube until the surface of the wear-resistant tube is completely coated with paint.

[0032] After the wear-resistant tube is painted, the operator manually rotates the handle on door 101 to open the machine casing 1. The operator then holds the painted wear-resistant tube and controls the telescopic part of the electric push rod 114 to move the corresponding sliding plate 112 and fixed plate 113 away from the wear-resistant tube. This causes the fixed plate 113 to be pulled out of the wear-resistant tube, releasing the two fixed plates 113 from fixing the wear-resistant tube. Finally, the operator removes the painted wear-resistant tube from the machine casing 1, thus completing the entire painting process of the wear-resistant tube.

[0033] It should be noted that before spraying the wear-resistant pipe, using a left-to-right view as a reference, first control the output shaft of the front motor 5 to drive the corresponding take-up rod 4 to rotate clockwise, causing the front take-up rod 4 to continuously unwind the connecting strip 7 and the recovery film 8. At the same time, control the output shaft of the rear motor 5 to drive the corresponding take-up rod 4 to rotate clockwise, causing the rear take-up rod 4 to continuously wind up the connecting strip 7. This allows the recovery film 8 to first pass through the front slide groove 601, then pass through all the rotating rods 3 counterclockwise in sequence, and finally pass through the rear slide groove 601. This causes the recovery film 8 to unwind from the wound state into a rectangular shape, so that the recovery film 8 covers the spraying pipe 2 and the wear-resistant pipe. Inside the spray pipe 2, during the process of spraying paint onto the surface of the wear-resistant pipe, when the paint mist in the air inside the housing 1 comes into contact with the inside of the recovery membrane 8, the paint mist will adhere to and condense on the surface of the recovery membrane 8, and then move along the surface of the recovery membrane 8 towards the discharge pipe 6, and finally enter the external recovery device for storage through the discharge pipe 6. In this way, the paint mist is recovered to reduce paint waste and avoid the problem that existing spraying equipment usually sprays paint directly onto the surface of the wear-resistant pipe, and a large amount of paint fails to adhere effectively to the surface of the wear-resistant pipe, but instead escapes into the air in the form of paint mist, resulting in a large amount of paint waste.

[0034] After the wear-resistant pipe surface is coated, using a left-to-right view as a reference, firstly, control the output shaft of the front motor 5 to drive the corresponding winding rod 4 to rotate counterclockwise, so that the front winding rod 4 continuously winds up the connecting strip 7 and the recycling film 8. At the same time, control the output shaft of the rear motor 5 to drive the corresponding winding rod 4 to rotate counterclockwise, so that the rear winding rod 4 continuously unwinds the connecting strip 7, so that the front winding rod 4 rewinds the recycling film 8 back to its initial state, so that the recycling film 8 no longer covers the coating pipe 2 and the wear-resistant pipe, allowing the worker to normally remove the coated wear-resistant pipe from the machine housing 1. Furthermore, during the winding process of the recycling film 8, the scraper 9 will scrape off the paint adhering to the surface of the recycling film 8, so that the scraped paint falls into the discharge pipe 6, further improving the paint recycling efficiency and ensuring the cleanliness of the recycling film 8, making it easy to use the recycling film 8 next time.

[0035] Considering that although the design of covering the spray pipe 2 and the wear-resistant pipe with the recycling membrane 8 can recover most of the escaping paint mist, a small amount of unrecovered paint mist still remains inside the recycling membrane 8. Therefore, during the process of the front winding rod 4 rewinding the recycling membrane 8 back to its initial state, the paint mist remaining inside the recycling membrane 8 will also enter the machine housing 1. That is, when the machine housing 1 is manually opened, the paint mist trapped inside the machine housing 1 will drift into the outside air, affecting the quality of the workshop environment and causing potential health risks.

[0036] Therefore, an air duct 10 connected to an external air pump is added. After the wear-resistant pipe surface is sprayed, the external air pump is controlled to send air to the inside of the recovery membrane 8 through the air duct 10. The air blows the paint mist remaining on the inside of the recovery membrane 8 into the external recovery device for storage through the discharge pipe 6, so as to avoid the problem that a small amount of unrecovered paint mist remains on the inside of the recovery membrane 8.

[0037] It should be noted that before the external air pump supplies air to the inside of the recycling membrane 8 through the air duct 10, firstly, control the electric slider 131 to drive the corresponding rotating rod 3, mounting plate 132, and limiting rod 133 to move closer to the annular limiting plate 134. Simultaneously, using a left-to-right view as a reference, control the output shaft of the front motor 5 to drive the corresponding winding rod 4 to rotate counterclockwise, causing the front winding rod 4 to continuously wind up the connecting strip 7 and the recycling membrane 8. At the same time, control the output shaft of the rear motor 5 to drive the corresponding winding rod 4 to rotate counterclockwise, causing the rear winding rod 4 to continuously unwind the connecting strip 7. This ensures that the connecting strip 7 and the recycling membrane 8 remain taut during the movement of the rotating rod 3, until the connecting strip 7 is... Figure 6 The state shown is in contact with the corresponding annular limiting plate 134, so that the recycling membrane 8, under the action of the connecting belt 7 and the annular limiting plate 134, will change from a rectangular state to a rectangular state. Figure 6 As shown in the diagram, the overall space covered by the recycling membrane 8, including the spray pipe 2 and the wear-resistant pipe, will be reduced, allowing the air blown from the duct 10 to be better connected to the external air pump and blow the residual paint mist inside the recycling membrane 8 into the discharge pipe 6, thereby accelerating the removal of the residual paint mist inside the recycling membrane 8.

[0038] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
