Description

Technical Field

[0001] The invention relates to the technical field of primer spraying and curing, in particular to an integrated machine for automatic spraying and surface curing of epoxy polyurethane primer. Background Art

[0002] Epoxy polyurethane primer is a high-performance coating that combines epoxy resin and polyurethane components. It is widely used in surface treatment of metal, concrete and other materials. It has excellent adhesion, corrosion resistance, wear resistance and weather resistance, and can effectively improve the durability of the coating. Epoxy polyurethane primer is usually used as the first layer of protective coating to provide good substrate surface treatment and ensure the adhesion and durability of subsequent coatings. Its advantages include faster curing speed, good mechanical strength and strong resistance to chemical corrosion. It is often used for anti-corrosion protection in industrial fields such as steel structures, ships, bridges, and storage tanks. At present, painting and curing are generally carried out separately, which is inefficient and time-consuming.

DETAILED DESCRIPTION

[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0029] Example 1 Reference Figure 1 to Figure 8 , which is the first embodiment of the present invention, provides an integrated machine for automatic spraying and surface curing of epoxy polyurethane primer, including a plate 100, a moving mechanism, an adjustment assembly and a light curing assembly, which is suitable for various uneven plate surfaces. The spraying efficiency of the nozzle 303 is bound to the moving speed and adaptively adjusted. The nozzle 303 can rotate when the platform 200 moves to improve the uniformity of primer spraying. At the same time, the curing lamp 402 is automatically adapted, which simplifies the operation steps and improves the efficiency of painting and curing.

[0030] Specifically, it includes a plate 100, wherein the plate 100 is a metal plate with an uneven surface; The moving mechanism includes a platform 200, wherein at least four moving wheels 201 are movably provided at the lower part of the platform 200, and the moving wheels 201 always roll in contact with the surface of the plate 100; The adjustment assembly includes a symmetrically arranged ball bearing 300 and a rotating wheel 301. A rotating table 302 is movably provided on the lower end surface of the platform 200. A nozzle 303 is provided on the rotating table 302. When the relative height of the ball bearing 300 changes, the rotating wheel 301 is driven to rotate. When the rotating wheel 301 rotates, the nozzle 303 is driven to adjust its angle. The light curing assembly includes a ratchet 400 and a rotating shaft 401 disposed at one end of the moving wheel 201. When the rotating shaft 401 rotates, the primer is driven to be sprayed out from the nozzle 303. A curing lamp 402 is also disposed on the turntable 302. When the rotating shaft 401 rotates, the curing lamp 402 is synchronously driven to rotate.

[0031] Among them, a bearing seat 2001 is provided on the lower end surface of the platform 200, the rotating shaft 401 is rotatably arranged in the bearing seat 2001, the ratchet part of the ratchet 400 is fixedly arranged on the outer wall of the moving wheel 201, and the moving wheel 201 is coaxially rotatably provided with a roller 2002, and one end of the roller 2002 is connected to the pawl part of the ratchet 400.

[0032] Preferably, in this embodiment, the platform 200 is provided with four moving wheels 201 and is distributed in a rectangular shape. The front and rear moving wheels 201 are both connected to a ratchet 400, and the two ratchet wheels 400 can rotate in opposite directions. Therefore, when the platform 200 moves forward, the front moving wheel 201 can drive the roller 2002 to rotate, and the rotation of the rear moving wheel 201 cannot drive the roller 2002 to rotate. When moving in the opposite direction, the rotatable rollers 2002 are distributed in the opposite situation.

[0033] More preferably, a pulley 2003 is provided at one end of the roller 2002 and one end of the rotating shaft 401 , a transmission belt 2024 is sleeved between the two pulleys 2003 , the rotating shaft 401 rotates through the turntable 302 , and the nozzle 303 rotates through the turntable 302 .

[0034] Furthermore, a first bevel gear 2004 is provided on the outer wall of the rotating shaft 401, and a second bevel gear 2005 is provided on one end of the nozzle 303 that passes through the turntable 302. The first bevel gear 2004 and the second bevel gear 2005 are meshingly connected. The turntable 302 is provided with at least two, and connecting blocks 2006 are provided between each of the turntables 302 for fixed connection.

[0035] Among them, the turntable 302 is a rectangular frame in the shape of a gate, and a rotating shaft 401 is provided to rotate through two parallel surfaces. The nozzle 303 is arranged perpendicular to the rotating shaft 401. When the nozzle 303 rotates around its own axis, the primer paint is evenly sprayed on the plate 100. The faster the displacement speed of the platform 200 and the faster the rotation speed of the rotating shaft 401, the faster the spraying speed of the paint is, thereby realizing automatic adjustment of the primer spraying amount and the movement efficiency of the platform 200.

[0036] An extension frame 2007 is fixedly provided on the turntable 302 , a curing shaft 2008 is rotatably provided on the extension frame 2007 , a curing lamp 402 is connected to the lower end surface of the curing shaft 2008 , and a reflective cover 2009 is sleeved on the outer wall of the curing shaft 2008 .

[0037] Furthermore, a driven wheel 2011 is further provided on the outer wall of the curing shaft 2008, a transmission wheel 2012 is provided on the lower end surface of the second bevel gear 2005, the transmission wheel 2012 is meshedly connected with the driven wheel 2011, and the curing lamps 402 are distributed in a circular array.

[0038] Among them, eight curing lamps 402 are provided in this embodiment. As the rotating shaft 401 rotates, the curing lamps 402 are driven to rotate to perform uniform light curing to prevent the occurrence of curing dead corners. In this embodiment, the moving wheels 201 are elastically slidably connected to the platform 200 through springs, thereby ensuring that each moving wheel 201 always rolls in contact with the surface of the plate 100.

[0039] In summary, when in use, when the moving wheel 201 rolls along the surface of the plate 100, the ratchet part on the ratchet wheel 400 drives the pawl part on the roller 2002 to rotate, thereby driving the pulley 2003 on the rotating shaft 401 to rotate through the transmission belt 2024. When the rotating shaft 401 rotates, the nozzle 303 is driven to rotate through the first bevel gear 2004 and the second bevel gear 2005. The faster the moving speed of the platform 200 is, the more primer is sprayed out by the nozzle 303, and the faster its own rotation frequency is, so as to ensure uniform spraying of the primer.

[0040] At the same time, the rotation speed of the curing lamp 402 itself also changes synchronously with the rotating shaft 401, so as to be synchronously adapted to the primer spraying efficiency to ensure the curing effect; when multi-layer painting is required, it can be achieved by directly moving the platform 200 in the opposite direction. At this time, the rotating shaft 401 in front stops rotating, and the nozzle 303 no longer sprays the primer, eliminating the steps of turning around or changing the order between the nozzle 303 and the curing lamp 402, simplifying the operation steps, and improving the painting and curing efficiency.

[0041] Example 2 Reference Figure 1 to Figure 8 , which is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but the difference is that the setting mode of the moving wheel 201 is changed to better fit the surface of the plate 100 to prevent slipping. At the same time, the angle of the nozzle 303 is controlled to adjust to prevent the blind area from not being painted due to a sudden change in the angle, thereby reducing the occurrence of excessive local painting and insufficient local painting.

[0042] Specifically, Figure 2 As shown, the moving wheels 201 are divided into two categories, the one on the right is the right driving wheel, and the one on the left is the left driving wheel. By arranging each moving wheel 201 in a zone, the moving wheel 201 can always fit the surface of the uneven plate 100 when rolling on it.

[0043] Among them, the two moving wheels 201 on the right are simultaneously provided with a balance bar 1001, and the balance bar 1001 is rotatably arranged on the platform 200. A first elastic member 1002 is arranged between the two moving wheels 201 on the left and the platform 200, and a material bin 1003 is arranged in an array on the platform 200.

[0044] The first elastic member 1002 is a spring with a large elastic coefficient, so that the two moving wheels 201 on the left side will press down the first elastic member 1002 to produce elastic deformation only when overloaded, to provide buffering and prevent the primer in the silo 1003 from spilling out due to vibration.

[0045] More preferably, the outer cover of the movable wheel 201 on the left side is provided with a hanging frame 1004, on which a folding wire cylinder 1005 is fixedly provided, a support arm 1006 is slidably provided inside the folding wire cylinder 1005, a second elastic member 1007 is provided between the support arm 1006 and the inner wall of the folding wire cylinder 1005, and a balance block 1008 is fixedly embedded in the middle area of ​​the second elastic member 1007.

[0046] Furthermore, in this embodiment, the folding line cylinder 1005 is a hollow cylinder in the shape of an acute folding line, and the support arm 1006 has two sliding arms 1006 respectively arranged on the two acute-angled edges of the folding line cylinder 1005. The center of the folding line cylinder 1005 coincides with the center of the moving wheel 201, and the second elastic member 1007 is a spring, and always pushes the support arm 1006 to slide outside the folding line cylinder 1005.

[0047] The ball bearing 300 is movably mounted on the support arm 1006 . As the moving wheel 201 moves forward, the two support arms 1006 roll forward through the ball bearing 300 . The ball bearing 300 always adheres to the surface of the plate 100 . The two support arms 1006 move synchronously with the moving wheel 201 .

[0048] More preferably, one end of the balancing block 1008 extending outside the folding tube 1005 is provided with a connecting rod 1009, and the other ends of the two balancing blocks 1008 corresponding to the connecting rod 1009 are respectively provided with a first rack 1011 and a second rack 1012, and the first rack 1011 slides through the second rack 1012.

[0049] Among them, an empty groove is opened between the second racks 1012, so that the first rack 1011 can slide in the second rack 1012, and the folding cylinder 1005 always moves synchronously with the hanging frame 1004, so as to always vertically contact the outer wall of the plate 100, and the rotating wheel 301 is fixedly connected to the turntable 302 and rotates synchronously therewith.

[0050] Preferably, the first rack 1011 and the second rack 1012 are meshedly connected with the rotating wheel 301 at the same time. In this embodiment, the two arms 1006 are 30° apart, so that the angle between the first rack 1011 and the second rack 1012 is 30°.

[0051] In summary, when in use, as the moving wheel 201 on the left enters the uphill area from the flat area, the support arm 1006 on the front side is first compressed and rebounds along the folding tube 1005, and then the second elastic member 1007 drives the balance block 1008 to move upward, and the connecting rod 1009 drives the second rack 1012 to slide upward, and the rotating wheel 301 rotates to drive the first rack 1011 to move downward, and pushes the support arm 1006 on the rear side to slide outward through the balance block 1008 and the second elastic member 1007, thereby increasing the squeezing force between the ball 300 and the surface of the plate 100 until the friction force increases and a balance is reached, thereby increasing the power and preventing slipping.

[0052] At the same time, as the rotating wheel 301 rotates, the turntable 302 is driven to rotate. At this time, the first bevel gear 2004 is relatively stationary, and the second bevel gear 2005 rolls around the first bevel gear 2004, thereby driving the nozzle 303 to rotate so that it is always perpendicular to the outer wall of the plate 100. Since the nozzle 303 is located at the moving wheel 201 on the front side, the angle can be adjusted in time according to the terrain there, and the angle can be adjusted slowly as it slowly goes uphill to keep the nozzle 303 at the optimal spraying angle, prevent the angle from changing too much suddenly, resulting in a blind area without painting, and reduce the occurrence of excessive local painting and insufficient local painting.

[0053] Example 3 Reference Figure 1-Figure 8 , which is the third embodiment of the present invention. This embodiment is based on the previous embodiment, but the difference is that the curing lamp 402 is no longer fixed, but is connected to the turntable 302 through a universal joint to adjust the distance between the curing lamp 402 and the sprayed primer, thereby adjusting the curing efficiency.

[0054] Specifically, the curing lamp 402 is connected to the turntable 302 by a universal joint. Under the action of gravity, the curing lamp 402 is always vertically downward. When only one painting is required, the painting and the first step of curing are performed in the manner described in the previous embodiment.

[0055] Among them, after the painting is completed, an end slope is set at the end point of the painting. When the support arm 1006 reaches the highest point of the end slope, it reaches the highest point and is locked in this position. Then the wheel 301 rotates, and the nozzle 303 flips upward and stops spraying, so that the curing lamp 402 and the turntable 302 rotate synchronously, the distance between the curing lamp 402 and the outer wall of the plate 100 changes, and the light intensity and the spacing change synchronously, so as to adjust the curing efficiency, and perform supplementary curing during reciprocating movement, thereby improving the curing effect and reducing the time required for curing.

[0056] Importantly, it should be noted that the construction and arrangement of the present application shown in a plurality of different exemplary embodiments are only exemplary. Although only a few embodiments are described in detail in this disclosure, it should be readily understood by those who refer to this disclosure that many modifications are possible (e.g., the size, scale, structure, shape and ratio of various elements, and parameter values ​​(e.g., temperature, pressure, etc.), installation arrangements, use of materials, color, directional changes, etc.) without substantially departing from the novel teachings and advantages of the subject matter described in the application. For example, an element shown as integrally formed can be composed of a plurality of parts or elements, the position of the element can be inverted or otherwise changed, and the nature or number or position of the discrete element can be changed or changed. Therefore, all such modifications are intended to be included within the scope of the present invention, and the order or sequence of any process or method steps can be changed or reordered according to alternative embodiments. The present invention is not limited to a specific embodiment, but extends to a variety of modifications that still fall within the scope of the appended claims.

[0057] Additionally, in order to provide a concise description of exemplary embodiments, all features of an actual embodiment may not be described (ie, those features that are not relevant to the best mode presently contemplated for carrying out the invention or those features that are not relevant to implementing the invention).

[0058] It will be appreciated that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will be a routine task of design, fabrication, and production for those of ordinary skill having the benefit of this disclosure without undue experimentation.

[0059] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
