Description

Technical Field

[0001] This invention relates to the field of exterior panel coating technology, specifically to an improved device for segmented coating of exterior panels with paint layer protection without adhesive tape. Background Technology

[0002] In shipbuilding, the term refers to the hull plating, specifically the outer bottom plating and side plating. The steel plates that make up the hull plating are arranged longitudinally along the ship's length, forming a long row called a plate row. In certain areas where the hull plating experiences significant stress, has openings, or is prone to corrosion and wear, it needs to be appropriately thickened. The outer bottom plating and side plating are collectively referred to as the hull plating. The joints between adjacent plate rows are called edge joints or longitudinal joints; the joints between individual plates within the same plate row are called end joints or transverse joints. Each row of plates is named according to its location. The row of plates along the centerline of the hull is called the keel flat or keel bottom plate. The rows of plates on either side of the keel bottom plate are called keel wing plates. From the keel bottom plate to the top plate, each row of plates is conventionally represented by the capital letters K, A, B, C… The keel bottom plate is simply called the K plate. The row of plates arranged along the bilge corners is called the bilge plate, or simply the bilge plate. The uppermost row of plates connecting to the upper deck is called the top plate or side top plate, or simply the S plate. Between these three rows of plates are other rows of outer plates. The bottom rows are called the bottom rows, and the rows on both sides are called the side rows, or simply the bottom plate and side plate, respectively.

[0003] The thickness of the outer plating varies across different sections due to variations in stress during longitudinal bending and the degree of corrosion during operation. In medium and large vessels, the thickness of the outer plating in the same row generally remains constant within a 0.4L range amidships, gradually decreasing towards both ends. Because the keel bottom plating bears significant support from the timbers during shipbuilding and dock repairs, and is located at the hull and susceptible to water corrosion, its thickness is greater than other rows of bottom plating, while its width remains constant throughout its length. For longitudinal strength considerations, the top plating is also thicker than other rows of side plating. Certain special sections of the outer plating, subjected to greater stress, with various openings, or prone to corrosion and wear, require appropriate thickening, such as the engine room area, the bow anchor chain hole area, the stern propeller area, and ice-resistant areas. The painting process for the straight and flat bottom areas of the segmented outer plating generally involves five coats of paint. To ensure proper layering and sanding during the slab assembly phase, each coat of paint at the slab assembly joint requires layered protection. Current layered protection methods involve applying adhesive tape tightly for each coat, generating significant paint waste after each section of painting, increasing the burden and cost of environmental disposal. The layered tape protection for each coat of paint incurs considerable labor and material costs. Furthermore, the removal and collection of tape after each section of painting incurs labor costs. Additionally, insufficient adhesion to the outer panel and foreign objects on the panel often result in poor paint adhesion. Moreover, paint peeling frequently occurs during navigation after painting. Repeated painting of the outer panel is time-consuming and labor-intensive, requiring multiple applications of layered tape, leading to wasted labor and costs. Therefore, we propose an improved tape-free layered paint protection device for sectioned painting of outer panels to solve these problems. Summary of the Invention

It solves the problem that paint often peels off after navigation, even after the paint has been applied. However, multiple coatings of outer panels are time-consuming and labor-intensive, and multiple applications of layered tape are required for covering, resulting in a waste of labor and costs.

The equipment includes a grinding assembly, a paint box on the upper surface of the base plate, a paint supply assembly inside the paint box, a bearing A on the upper surface of the paint box, a shaft B inside the bearing A, a painting wheel on the outer surface of the shaft B, a painting drive wheel at one end of the shaft B, a spraying seat on the upper surface of the base plate, a sprayer inside the spraying seat, a nozzle on the upper surface of the sprayer, a water pump on the side surface of the sprayer, and a water tank on the other side of the water pump.

[0008] Preferably, the grinding support arm assembly includes a support arm seat, a positioning bolt, and an extension arm. The support arm seat is inserted into one side of the equipment base plate, and the positioning bolt passes through the internal thread of the support arm seat. The extension arm passes through the support arm seat through the positioning bolt.

[0009] Preferably, the polishing assembly includes a polishing motor, a polishing shaft, and polishing rollers. The polishing motor is inserted into the inside of the extension arm, and a polishing shaft is inserted into one end of the polishing motor. A polishing roller is sleeved on the outer surface of the polishing shaft.

[0010] Preferably, the paint box includes a paint box, a paint box cover, and a closing plate. The paint box is inserted into the upper surface of the equipment base plate, the paint box cover is snapped onto the upper surface of the paint box, and the closing plate is snapped onto the inside of the paint box cover.

[0011] Preferably, the paint supply assembly includes a paint supply shaft, a paint supply drive wheel, and paint supply blades. The paint supply shaft is rotatably connected inside the paint box. One end of the paint supply shaft is fitted with the paint supply drive wheel, and the surface of the paint supply shaft is fitted with paint supply blades.

[0012] Preferably, a bolt seat is inserted into the lower surface of the equipment base plate, and hand-tightening bolts pass through both sides of the bolt seat.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides an improved device for segmented coating of outer panels with paint layer protection without adhesive tape, which has the following beneficial effects:

[0018] 1. This improved tape-free paint layer protection device for segmented coating of outer panels uses an electromagnet regulating valve to adjust the magnetic strength of the electromagnet, making manual operation during coating more convenient. It avoids the inconvenience of pushing the equipment due to excessive magnetic force and the hand fatigue of manually lifting the equipment due to insufficient magnetic force. After adjusting the height, paint is placed inside the paint box, and the paint box cover is closed. The paint supply blades rotate to supply paint to the coating wheel. It is worth noting that the coating drive wheel and the paint supply drive wheel on one side of the coating wheel are in contact with each other. During the initial coating, pushing the coating drive wheel of this device will open the closed cover, at which time the paint will be supplied normally. At the same time, it can also prevent paint from being exposed when installing the paint box.

[0019] 2. This improved tape-free paint layer protection device for segmented painting of the outer hull allows for length adjustment by pressing down the fixing head of the locator and pushing the second extension rod. Under the action of shaft A, the edging roller can move parallel, avoiding jamming. Simultaneously, when painting other parts of the hull hull is required, the first extension rod can be removed for painting, avoiding the need to change painting tools and increasing work efficiency. During initial painting, the sanding roller can sand the hull hull. When sanding the hull hull, the angle of the extension arm can be adjusted using the positioning bolts to adjust the contact surface between the sanding roller and the hull hull, avoiding over-sanding due to an excessively large contact surface. Simultaneously, the sanding assembly can be flipped out and closed to directly proceed with painting, avoiding the need to change painting tools and further increasing work efficiency.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figures 2-8 The equipment includes a base plate 1, an electromagnet 2 inserted into the upper surface of the base plate 1, a first extension rod 3 inserted into one side of the base plate 1, a positioner 4 inserted into one side of the first extension rod 3, a second extension rod 5 inserted into the other side of the positioner 4, a shaft A6 inserted into the upper surface of the second extension rod 5, an edged roller 7 sleeved on the outer surface of the shaft A6, a grinding support arm assembly 8 inserted into one side of the base plate 1, and a grinding assembly 9 inserted into the interior of the grinding support arm assembly 8. A paint box 10 is inserted into the upper surface, and a paint supply assembly 11 is inserted into the inside of the paint box 10. A shaft seat A12 is inserted into the upper surface of the paint box 10, and a shaft B13 is inserted into the inside of the shaft seat A12. A painting wheel 14 is sleeved on the outer surface of the shaft B13, and a painting drive wheel 15 is inserted into one end of the shaft B13. A sprayer seat 16 is inserted into the upper surface of the equipment base plate 1, and a sprayer 17 is inserted into the inside of the sprayer seat 16. A nozzle 1701 is inserted into the upper surface of the sprayer 17.

[0032] A water pump 18 is inserted into the side surface of the sprayer 17, and a water tank 19 is inserted into the other side of the water pump 18. According to existing technology, the painting process for the straight bottom and flat bottom areas of the segmented outer plate generally involves five coats of paint. To ensure the layered sanding and painting of each coat of paint on the outer plate in the docking area during the segmentation stage, each coat of paint at the outer plate docking joint needs to be protected with a layer of paint. Currently, layered protection is achieved by using adhesive tape to tightly adhere each coat. This generates a large amount of paint waste after each segment is painted, resulting in significant cost waste. Furthermore, manual application of the tape requires reaching the top, increasing the risk and burden of environmental disposal, as well as costs and safety concerns. The layered tape protection for each coat of paint incurs considerable labor and material costs, and the removal and collection of the tape after the segmented painting is completed also incurs certain labor costs.

[0033] The device is attached to the surface of the hull by an electromagnet 2 inserted into the upper surface of the device base plate 1, so that the grinding assembly 9 and the painting wheel 14 come into contact on the hull for grinding and painting. During painting, paint is put into the paint box 10. After closing the paint box cover 1102, the closing plate 1003 is pushed to the closed state. The paint is supplied to the painting wheel 14 by the rotation of the paint supply blade 1103. It is worth noting that the painting drive wheel 15 and the paint supply drive wheel 1102 on one side of the painting wheel 14 are in contact with each other. During the initial painting, pushing the painting drive wheel 15 of this device will push the closing cover 1003 to the open state, at which time the paint will be supplied normally.

[0034] The grinding rollers 903 provided in the grinding assembly 9 can be used to grind the outer hull plate. When grinding the outer hull plate, the angle of the extension arm 803 can be adjusted by the positioning bolts 802 to adjust the contact surface between the grinding rollers 903 and the outer hull plate, thus avoiding over-grinding caused by an excessively large contact surface. At the same time, the grinding assembly 9 can be flipped out to close the grinding state and paint can be applied directly.

[0035] The hardener and antioxidant placed inside the water tank 19 can be sprayed out through the nozzle 1701 to coat the paint surface after the painting is completed. It is worth noting that the surface of the sprayer 17 is equipped with 4 nozzles 1701, which can perform coating operations on the painted hull plate over a large area, thus better ensuring the coating effect.

[0036] The device can be positioned by using the edging roller 7. When adjustment is needed, the fixed head of the positioner 4 can be pressed down to push the second extension rod 5 to adjust the length. Under the action of the shaft A6, the edging roller 7 can move in parallel to avoid jamming. At the same time, when it is necessary to paint other parts of the hull plate, the first extension rod 3 can be removed for painting, avoiding the need to change painting tools and increasing work efficiency.

[0037] like Figure 9 As shown, the first telescopic rod 22 and the second telescopic rod 24 can be adjusted according to the height of the hull plating via the limiter 23. A battery 26 is installed inside the second telescopic rod 24. Notably, the magnetic strength of the electromagnet 2 is adjusted by regulating the electromagnet regulating valve 25, which facilitates manual operation during painting, avoiding the difficulty of pushing the equipment due to excessive magnetic force and the hand fatigue caused by manually lifting the equipment due to insufficient magnetic force. The electromagnet regulating valve 25 used in this device compares the measured value of the parameter during the energization process of the electromagnet 2 with the given value. After obtaining the deviation, it generates an output signal according to a certain adjustment rule to drive the actuator to eliminate the deviation, keeping the parameter near the given value or according to a predetermined value. The controller, which operates according to a set pattern, can control the magnetic strength of electromagnet 2. The device is equipped with an L298N driver, a dual-channel full-bridge motor driver chip capable of accepting high voltage and high current. It operates at up to 46V and can output up to 4A. It employs a dynamic adjustment circuit and has a logic power input terminal. Through a built-in 78MO5 voltage regulator chip, the internal logic circuitry can operate at low voltage, while also outputting a 5V logic voltage. All electrical components mentioned in this document are connected to the external L298N main controller and 220V AC mains power. The main controller can be a computer or other conventionally known control device.

[0038] In use, the limiter 23 can be used to adjust the first telescopic rod 22 and the second telescopic rod 24. A battery 26 is located inside the second telescopic rod 24. It is worth noting that the magnetic strength of the electromagnet 2 can be adjusted by regulating the electromagnet regulating valve 25, which facilitates manual operation during painting and avoids difficulties in pushing the equipment due to excessive magnetic force or hand fatigue when manually lifting the equipment due to insufficient magnetic force. After adjusting the height, paint is placed inside the paint box 10, and the paint box cover 1102 is closed, followed by the closing plate 1003. When pushed to the closed position, the paint supply blade 1103 rotates to supply paint to the painting wheel 14. It is worth noting that the painting drive wheel 15 and the paint supply drive wheel 1102 on one side of the painting wheel 14 are in contact with each other. During the initial painting process, pushing the painting drive wheel 15 will open the closed cover 1003, at which point the paint will be supplied normally. The electromagnet 2, inserted into the upper surface of the equipment base plate 1, causes the equipment to adhere to the surface of the hull hull, allowing the sanding assembly 9 to contact the painting wheel 14 for sanding and painting on the hull hull. When adjusting the edge angle of the hull hull plating, pressing down the fixing head of the locator 4 and pushing the second extension rod 5 allows for length adjustment. Under the action of shaft A6, the edging roller 7 can move parallel, preventing jamming. Simultaneously, when painting other parts of the hull hull plating, the first extension rod 3 can be removed for painting, avoiding the need to change painting tools and increasing work efficiency. During initial painting, the sanding roller 903 can sand the hull hull plating. When sanding the hull hull plating, the extension arm 80 can be adjusted using the positioning bolt 802. The angle of 3 allows for adjustment of the contact surface between the sanding roller 903 and the hull plate, avoiding over-sanding caused by an excessively large contact surface. Simultaneously, the sanding assembly 9 can be flipped out to close the sanding state and directly proceed with painting. The hardener and antioxidant stored inside the water tank 19 can be sprayed out through the nozzle 1701. After painting, a film is applied to the paint surface. It is worth noting that the sprayer 17 has four nozzles 1701 on its surface, enabling large-area film application to the painted hull plate, thus better ensuring the film's effectiveness.

[0039] In summary, this improved tape-free paint layer protection device for segmented coating of outer panels, by adjusting the magnetic strength of the electromagnet through a regulating valve, facilitates manual operation during coating. It avoids the problems of excessive magnetic force causing difficulty in pushing the equipment and insufficient magnetic force causing hand fatigue when manually lifting the equipment. The device utilizes a coating drive wheel and a paint supply drive wheel located on one side of the coating wheel. During initial coating, pushing the coating drive wheel opens the closed cover, allowing for normal paint supply. This also prevents paint leakage when installing the paint box. In this case, the length can be adjusted by pressing down the fixing head of the locator to push the second extension rod. Under the action of shaft A, the edging roller can move in parallel to avoid jamming. By removing the first extension rod for painting, the need to change painting tools is avoided, increasing work efficiency. The angle of the extension arm can be adjusted by adjusting the positioning bolt to adjust the contact surface between the grinding roller and the hull plate, avoiding over-grinding caused by an excessively large contact surface. At the same time, the grinding set can also be flipped out and the grinding state closed by the above operation, and painting can be carried out directly without changing painting tools.
