Description

Technical Field

[0001] The utility model relates to the field of equipment component surface material brushing devices, in particular to an adaptive plate surface material spraying device. Background Art

[0002] When producing wooden furniture or flooring, in order to enhance its durability and improve its appearance and feel, the corresponding surface material coating is usually applied on the surface of the board. These material layers usually include primer, topcoat and other special coatings. Among them, the primer, as the first layer of the coating system, mainly plays the role of enhancing the adhesion between the coating and the wood, filling the small pores on the wood surface and smoothing the surface. It provides a good foundation for the subsequent coating layer, ensuring that the topcoat can be evenly applied, improving the durability and beauty of the overall coating; while the topcoat is the last layer of the coating, which is in direct contact with the external environment. Its main function is to protect the wood from external factors such as moisture, chemicals, ultraviolet rays, etc., and also give the wood a specific gloss and color. There are many types of topcoats, including matte, semi-matte and high gloss products with different effects, and you can choose the appropriate effect according to your needs. Of course, in addition to conventional primers and topcoats, some special functional coatings may also be used, such as waterproof coatings, fire retardant coatings, etc., to provide additional protection.

[0003] At present, there are also some devices on the market that can realize the spraying treatment of the coating material on the surface of the plate, such as a plate spraying device disclosed in the Chinese invention patent application document with application number CN202310889457.1, which belongs to the field of plate spraying technology, including an operating table, a square plate located on the top of the operating table, a limiting structure and an extrusion structure on the top of the operating table, and a pushing structure installed on the operating table, wherein the limiting structure includes: a sliding plate slidably installed in the card slot at the top of the operating table, an L-shaped limiting member on the top of the sliding plate, a roller between the sliding plate and the L-shaped limiting member, a central axis inserted on the sliding plate, the L-shaped limiting member and the roller to limit the position of the roller, a connecting plate fixed on the top of the sliding plate away from the center of the operating table, a connecting block fixed on the top of the connecting plate, and a knob threadedly connected to the connecting block, wherein the roller rotates and is attached to one side of the square plate. The plate spraying device can constrain the position of the square plate through the limiting structure and the extrusion structure when the square plate needs to be sprayed, thereby improving the stability of its position when the square plate is sprayed. Another example is a plate spraying equipment disclosed in the Chinese invention patent application document with application number CN202311784912.8, which includes a conveying table, a plate and a dust removal component are arranged on the upper side of the conveying table, a moving rod is arranged on the outer side of the conveying table, a moving table is arranged on the side of the moving rod, an elastic sheet is arranged on the inner side of the moving table, a first limit plate and a second limit plate are connected at both ends of the elastic sheet, a steering wheel is rotatably arranged on the inner side of the moving table, a positioning block arranged between the elastic sheet and the second limit plate is installed on the outer side of the steering wheel, a spray head is arranged on the outer side of the steering wheel, and a push block is arranged on the side of the spray head; after the dust removal assembly removes dust from the plate, the moving rod and the moving table drive the spray head to move and spray the plate, and the spray head moves to the middle of the moving rod and is pushed by the push block, so that the positioning block slides over the elastic sheet while the steering wheel rotates, and is clamped between the elastic sheet and the first limit plate, so as to facilitate the adjustment of the inclination direction of the spray head, and to solve the problem that the existing spray machine is inconvenient to spray wooden plates with grooves on the surface as much as possible.

[0004] However, the applicant found that when manufacturing some items such as coffee tables and cabinets that have certain artistic shapes and aesthetic requirements, when the panels used for these items are produced and processed, the processors will cancel the step of grinding and smoothing them, but retain some of the bumps and even scar structures on the surface of the panels, and then apply a layer of coating material with curing and anti-corrosion functions, such as varnish or anti-corrosion material layer. However, in such a processing scenario, due to the uneven surface structure formed by the panel itself, when using these common material spraying equipment for processing, it is easy to cause the coating thickness to vary in various locations on the panel, and there may even be a situation where the coating is extremely thick in some parts, while other parts are thin or even exposed.

[0005] In response to the above problems, the utility model provides an adaptive plate surface material spraying device that can adaptively adjust the distance between the nozzle and the product to be processed for plate products with uneven surfaces, thereby effectively ensuring the consistency of the thickness of the plate surface coating and greatly improving the surface treatment quality of the product.

[0029] The following specific embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make modifications to the embodiments without any creative contribution as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.

[0030] This solution is achieved through the following technical means:

[0031] Embodiment: In this embodiment, a structural scheme for implementing an adaptive plate surface material spraying device is provided. Specifically, the device first includes a supporting platform 2 installed at the bottom in the shape of a rectangular block, and the supporting platform 2 is made of aluminum alloy material to ensure the stability of the device as a whole during operation. It should be noted here that the plate product 1 that needs to be surface sprayed is not only uneven on the upper surface that needs to be sprayed, but also may have a similar uneven state on its lower surface. Under this structure, if the plate is simply placed on a flat workbench, it is likely to cause swaying due to the unstable center of gravity of the plate. Obviously, such movement will affect the stability of the material spraying and easily lead to the problem of poor quality of the surface coating.

[0032] Considering the above problems, a supporting assembly 3 is provided on the supporting platform 2 in the present embodiment for stably and reliably supporting the plate product 1 with an irregular bottom surface. The supporting assembly 3 includes a plurality of groups of adaptive supporting mechanisms 301 arranged at the central area of ​​the supporting platform 2 for placing the plate product 1. The specific structure of the supporting mechanism can be found in the attached manual. Figure 3 The structural diagram is given for explanation.

[0033] In the aforementioned adaptive support and support mechanism 301, firstly, a cylindrical slot portion 3011 concave downwardly is provided on the support platform 2 in the vertical direction, and a cylindrical support column 3012 is installed in the slot portion 3011. The support column 3012 can be lifted and moved in the vertical direction in the slot portion 3011, and a spring member 3013 is provided between the bottom of the support column 3012 and the bottom surface of the slot portion 3011. At the same time, a plurality of locking holes 3014 extending in the horizontal direction and penetrating the two sides of the support column 3012 are provided on each support column 3012. A positioning plug hole 3015 penetrating from the outside to the inside to the position of the slot portion 3011 is provided on the support platform 2. When a plate component with an irregular concave-convex bottom surface is placed in the processing area near the center of the support platform 2, the weight of the plate component itself will press down the top support column 3012 in each adaptive top support mechanism 301 to varying degrees and maintain it in a stable state. At this time, the staff only needs to use a slender metal locking rod 3016 to pass through the positioning plug hole 3015 and the locking hole 3014 from the outside to the inside in turn, so as to lock and fix at least one top support column 3012. Of course, the instructions attached to the manual are as follows. Figure 3 Taking the structure shown in as an example, a locking rod 3016 can also be used to simultaneously and sequentially pass through multiple locking holes 3014 opened on different supporting top columns 3012 to achieve stable support for the bottom of the sheet product 1 at multiple positions at one time, thereby effectively avoiding the shaking of the sheet to be sprayed and reducing the quality of the spraying process.

[0034] Of course, as a preferred structure, a flexible pad 3017 made of rubber and protruding upward in a hemispherical shape can also be installed on the top of the supporting column 3012 to avoid damage to the sheet product 1 during the fixing process.

[0035] In order to fix the plate product 1 in the horizontal direction, a transverse clamping mechanism 7 for positioning the plate product 1 in the horizontal direction needs to be provided on the supporting platform 2. Specifically, the transverse clamping mechanism 7 includes a limit block 701 provided at one end of the supporting platform 2, and a transverse clamping assembly 702 installed at the other end of the supporting platform 2. Figure 1 and 2In the structure shown, the transverse clamping assembly 702 can be a connecting block fixed on the supporting platform 2 and having a threaded hole in the horizontal direction, and an adjustable screw screwed on the connecting block. When the plate is locked and fixed transversely, one end of the plate can be supported and fixed with the limit block 701, and the other end can be supported and clamped by rotating the adjustable screw.

[0036] After the installation and fixation of the plate product 1 is completed, the process of spraying the surface coating material can be carried out. Specifically, the adaptive spraying assembly 4 which is also arranged on the supporting platform 2 is used to realize the process treatment step. The adaptive spraying assembly 4 here includes a movable stand 401 arranged on the supporting platform 2, and the movable stand 401 includes a base column part 402 for connecting with the supporting platform 2, and a spraying bracket part 403 which can be lifted and moved in the vertical direction relative to the base column part 402. Refer to the attached manual Figure 1 In order to realize the reciprocating translational motion of the movable platform 401 and the various parts installed thereon in the horizontal direction, it is necessary to form a mutually engaged guide rail sliding structure between the lower end of the base column part 402 and the outer side surface of the supporting platform 2. Of course, in order to drive the translational motion of the movable platform 401, the cooperation of the stepping motor and the gear set can be used, and of course the chain transmission structure can also be used. Since such a structure is relatively mature and common, it will not be elaborated here. On the aforementioned base column, a probe rod 6 extending forward is installed, and a downward detection probe 601 is installed at the lower end of the probe rod 6. A spray head 502 is installed at the lower front end of the aforementioned spray bracket part 403, and a spray discharge device 5 is also installed at the upper end of the spray bracket part 403. A coating material transmission pipe 501 is connected between the lower end of the spray discharge device 5 and the spray head 502. The spraying and discharging device 5 here integrates the functions of storing coating materials and pressurizing and delivering liquid coating materials with sufficient pressure to the coating material transmission pipe 501, which will not be further described here.

[0037] As an important improvement of this embodiment scheme compared with the conventional spraying device, it is that the aforementioned detection probe 601 includes a device capable of identifying and judging the distance between it and the surface of the plate below at the coordinate position, for example, it can be realized by using a photoelectric distance measuring probe or a visual recognition probe; and the detection probe 601 here is electrically connected to the driving device for controlling the relative lifting movement between the spraying support part 403 and the base column part 402 in the movable stand 401. Then at this time, as the movable stand 401 moves and the spray head 502 continues to spray the coating material outward in a stable state, the detection head is always fixed to the base column part 402, so its height will not change, and it can send multiple sets of continuous X-axis coordinates and Y-axis coordinates on the left side that can reflect the undulating state of the plate surface obtained during the movement to the processor. After a relatively suitable spacing value is preset between the nozzle head 502 and the spraying position point on the plate surface, the processor can send a signal to the movable stand 401 and control the spraying support part 403 to move up and down, thereby ensuring that the coating material discharged from the nozzle of the nozzle head 502 always maintains a relatively constant and suitable spacing value with the surface of the plate, thereby improving the spraying processing quality of the surface coating.

[0038] As a preferred structure, refer to the attached Figure 4 As shown, a rotation adjustment mechanism 503 may be formed between the spray head 502 and the spray support 403 to adjust the angle of the nozzle on the spray head 502 relative to the plate product 1. For example, the rotation adjustment mechanism 503 here may select a gear transmission component to achieve precise adjustment of the deflection angle of the spray head 502.

[0039] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the utility model, and these modifications or replacements should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
