[0045] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0046] This utility model discloses a multifunctional facade spraying device, such as Figures 1-3As shown, it includes: a spraying panel 001 and a clamping mechanism 004;
[0047] The spraying panel 001 is provided with a first horizontal slide groove 103 and a second horizontal slide groove 104 in parallel; the clamping mechanism 004 is provided with a first clamping plate 401 and a second clamping plate 402 that are perpendicular to the first horizontal slide groove 103 and the second horizontal slide groove 104; the first clamping plate 401 and the second clamping plate 402 are slidably connected to the first horizontal slide groove 103 and the second horizontal slide groove 104 through a slider, and both the first clamping plate 401 and the second clamping plate 402 can achieve horizontal displacement through the slider.
[0048] The clamping surfaces of the first clamping plate 401 and the second clamping plate 402 are matched with the side of the component to be sprayed, and can maintain the angle between the first horizontal slide 103 and the second horizontal slide 104 and undergo horizontal displacement, forming a clamping area between the first clamping plate 401 and the second clamping plate 402.
[0049] A linkage structure is provided between the first clamping plate 401 and the second clamping plate 402. When one of the first clamping plate 401 and the second clamping plate 402 is moved, the other clamping plate moves in the opposite direction.
[0050] During implementation, the spraying operator can move the first clamp 401 or the second clamp 402 with one hand to clamp or release the component to be sprayed. This frees up one hand for positioning the component to be sprayed, thus enabling one spraying operator to position and clamp the component to be sprayed, greatly improving work efficiency and reducing labor costs.
[0051] It should be noted that existing facade spraying devices often contain two or more clamps, and at least two people are often required to fix the components to be sprayed; at least one person positions the clamps to ensure that their spacing matches the size of the components to be sprayed, and another person adjusts the position of the components to be sprayed so that they match the clamps and do not slip off under the influence of gravity.
[0052] Specifically, the linkage structure includes: a first slide rail 403, a second slide rail 404, a first spring 405, and a second spring 406;
[0053] The first slide rail 403 and the second slide rail 404 are coaxially connected to form a deformable X-shaped cross structure. The first slide rail 403 and the second slide rail 404 can rotate freely in a plane parallel to the spraying plane relative to their own center.
[0054] The first slide rail 403 is divided into two non-connected sliding areas by its center, and the second slide rail 404 is divided into two non-connected sliding areas by its center.
[0055] One end of the first spring 405 is fixedly connected to one end of the first clamping plate 401 and placed in a sliding area of the first slide rail 403, and can move freely in the sliding area; the other end of the first spring 405 is fixedly connected to one end of the second clamping plate 402 and placed in a sliding area of the second slide rail 404, and can move freely in the sliding area.
[0056] One end of the second spring 406 is fixedly connected to the other end of the first clamping plate 401 and placed in another sliding area of the first slide rail 403, and can move freely in the sliding area;
[0057] The other end of the second spring 406 is fixedly connected to the other end of the second clamping plate 402 and placed in another sliding area of the second slide rail 404, and can move freely in that sliding area.
[0058] In practice, taking the example of a spraying operator controlling the displacement of the first clamping plate 401 with one hand to clamp or release the first clamping plate 401 and the second clamping plate 402 onto the component to be sprayed, as follows: Figure 2 As shown:
[0059] When preparing to clamp the painting assembly, the painter first controls the first clamping plate 401 with one hand to move it away from the second clamping plate 402. Simultaneously, one end of the first spring 405 and the second spring 406, which are fixedly connected to the first clamping plate 401, moves horizontally within the first horizontal slide groove 103 and the second horizontal slide groove 104, respectively, and slides within the corresponding sliding area of the first slide rail 403 or the second slide rail 404. This applies force to the first slide rail 403 or the second slide rail 404. Because the first spring 405 and the second spring 406 slide in different directions on the first slide rail 403 or the second slide rail 404... Therefore, the forces acting on the first slide rail 403 and the second slide rail 404 are in different directions, which causes the first slide rail 403 to rotate counterclockwise and the second slide rail 404 to rotate clockwise. This causes the first slide rail 403 and the second slide rail 404 to exert a force on the other end of the first spring 405 and the second spring 406 that moves away from the first end of the spring. This causes the second clamping plate 402, which is fixedly connected to the other end of the first spring 405 and the second spring 406, to move away from the first clamping plate 401. A large displacement is left between the second clamping plate 402 and the first clamping plate 401, providing a space for the assembly to be sprayed.
[0060] After the component to be painted is positioned, the painter uses their second hand to manually fix the component to be painted, while the first hand releases the first clamping plate 401. Under the tension of the first spring 405 and the second spring 406, the first slide rail 403 rotates clockwise and the second slide rail 404 rotates counterclockwise. The two ends of the first spring 405 and the two ends of the second spring 406 move towards each other, which drives the first clamping plate 401 and the second clamping plate 402 to move until their distance is just enough to clamp and engage the component to be painted, thus achieving the clamping and fixing of the component to be painted.
[0061] When preparing to release the component to be sprayed, the spraying operator first controls the first clamp 401 to move away from the second clamp 402 with one hand, the steps are the same as when preparing to clamp the component to be sprayed.
[0062] It should be noted that the second clamping plate 402 and the first clamping plate 401 can also be used to clamp or release the component to be sprayed by the spraying operator controlling the displacement of the second clamping plate 402 with one hand. The process will replace the active operation of the first clamping plate 401 with the second clamping plate 402.
[0063] Compared with the prior art, this utility model sets up a first clamping plate and a second clamping plate with a linkage structure, so that when the first clamping plate or the second clamping plate is moved, the other clamping plate moves in the opposite direction. This allows the spraying operator to move the first clamping plate or the second clamping plate with one hand to clamp or release the component to be sprayed, freeing up one hand for positioning the component to be sprayed. This enables one spraying operator to position and clamp the component to be sprayed, greatly improving work efficiency and reducing labor costs.
[0064] Preferably, the first clamping plate 401 and the second clamping plate 402 are detachable, and the first clamping plate and the second clamping plate with different clamping surfaces are selected according to the different sides of the component to be sprayed.
[0065] Compared with the prior art, this utility model sets the first clamping plate and the second clamping plate as detachable structures, and matches the side of the component to be sprayed with the clamping surfaces of the first clamping plate and the second clamping plate, so that the clamping mechanism can adapt to components of different shapes and sizes to be sprayed, greatly expanding the types of components that can be processed to be sprayed.
[0066] Specifically, the multi-functional facade spraying device also includes a support structure 002 and an angle adjustment mechanism 003; the spraying panel 001 is connected to the support structure 002 through the angle adjustment mechanism 003 and can rotate to adjust its angle relative to the horizontal plane.
[0067] Specifically, the angle adjustment mechanism 003 is equipped with a rotating shaft 307;
[0068] The spraying panel 001 includes a spraying plane 101, and two supporting side plates 102 are provided on opposite sides of the spraying plane 101.
[0069] The support structure 002 includes a bracket 201 and a base 202; there are two brackets 201, which are vertically fixed to the base 202 and are distributed on opposite sides of the base 202.
[0070] The rotating shaft 307 passes through the two supporting side plates 102 and is fixedly connected to the supporting side plates 102;
[0071] The two ends of the rotating shaft 307 are movably connected to the two supports 201, and can rotate freely relative to the supports 201 with its own axis as the center.
[0072] During implementation, when the rotating shaft 307 rotates freely relative to the support 201, it can drive the spraying panel 001 to rotate coaxially, thereby achieving the adjustment of the angle of the spraying panel 001 relative to the horizontal plane, and thus achieving the adjustment of the spraying angle.
[0073] Preferably, the angle adjustment mechanism 003 further includes a ratchet mechanism, which adjusts the rotation angle of the rotating shaft to achieve the angle adjustment of the sprayed panel.
[0074] Preferably, the ratchet mechanism includes a ratchet 301 and a pawl 306, with the ratchet 301 located at one end of the rotating shaft extending out of the bracket, and the rotating shaft 307 extending out of one end of the bracket 201;
[0075] The angle adjustment mechanism 003 is also equipped with a pedal 302, a connecting rod 303 and a first rebound structure 304;
[0076] The fixed part of the pedal 302 is fixed to the base 202, and the moving part is fixedly connected to one end of the connecting rod 303; a first rebound structure 304 is provided between the fixed part and the moving part of the pedal 302, which is used to compress and store energy when the pedal 302 is subjected to pressure, and to restore the displacement of the fixed part and the moving part to the initial position after the pressure is released.
[0077] The other end of the connecting rod 303 is fixedly connected to the pawl 306. When the ratchet 301 rotates to different angles, the pawl 306 can engage with it, so that the rotation angle of the ratchet 301 can be fixed, thereby fixing the angle between the spraying plane 101 and the plane at the target angle.
[0078] During implementation, the spraying operator steps on pedal 302, causing the connecting rod 303 and pawl 306 to move downwards. The pawl 306 and ratchet 301 are disengaged and locked. The spraying operator can adjust the angle of the spraying plane 101 relative to the horizontal plane by hand. After the spraying plane 101 reaches the target position, the spraying operator releases the external force on the foot pedal 302. Under the action of the first rebound structure 304, the moving part of the pedal 302 drives the connecting rod 303 and pawl 306 to move upwards and reset, restoring the engagement and locking state of the pawl 306 and ratchet 301, thereby fixing the angle of the spraying plane 101 relative to the horizontal plane.
[0079] It should be noted that the ratchet has radial teeth on its rim, and the pawl is set parallel to the ratchet's axis and is kept in contact with the ratchet teeth by a spring or other device. When the ratchet rotates in one direction, the pawl slides over the ratchet teeth, allowing the ratchet to rotate freely. When the ratchet attempts to rotate in the opposite direction, the pawl gets stuck on the ratchet teeth, preventing the ratchet from rotating in the opposite direction.
[0080] Compared with the prior art, this utility model, through ratchet, pedal, connecting rod, first spring structure for pedal return, and pawl for engaging the connecting rod, enables the spraying operator to make stepless free adjustment of the angle of the spraying plane relative to the horizontal plane by a single person, one hand, and one foot. Compared with the prior art which requires at least two people to operate, this greatly reduces manpower and improves operating efficiency.
[0081] On the other hand, the infinitely adjustable angle between the spraying plane and the horizontal plane allows operators to appropriately reduce the angle with the horizontal plane, improve sagging, and thus select the optimal spraying angle.
[0082] Specifically, the ratchet 301 includes protrusions 3011 and recesses 3012 spaced apart, and the pawl 306 can engage and be fixed to the recesses 3012 between two adjacent protrusions 3011.
[0083] Preferably, the other end of the connecting rod 303 is also provided with a second spring structure 305, one end of the second spring structure 305 is fixedly connected to the connecting rod 303, and the other end is fixedly connected to the bracket 201;
[0084] When the pedal 302 is subjected to pressure, the second rebound structure 305 stretches and stores energy; after the pressure on the pedal 302 is released, the second rebound structure 305 assists the pawl 306 to engage with the recess 3012.
[0085] Preferably, the bottom of the base 202 is also provided with casters 203 to facilitate the movement of the spraying device.
[0086] To better illustrate this utility model, the following embodiments are further provided:
[0087] Example
[0088] This embodiment discloses a multifunctional facade spraying device, such as... Figures 1-3 As shown, it includes: a spraying panel 001, a support structure 002, an angle adjustment mechanism 003, and a clamping mechanism 004;
[0089] The spraying panel 001 is provided with a first horizontal slide groove 103 and a second horizontal slide groove 104 that are parallel to each other; the clamping mechanism 004 is provided with a first clamping plate 401 and a second clamping plate 402 that are perpendicular to the first horizontal slide groove 103 and the second horizontal slide groove 104. The clamping surfaces of the first clamping plate 401 and the second clamping plate 402 are matched with the side of the component to be sprayed, and can maintain a constant angle with the first horizontal slide groove 103 and the second horizontal slide groove 104 while undergoing horizontal displacement.
[0090] A linkage structure is provided between the first clamping plate 401 and the second clamping plate 402. When one of the first clamping plate 401 and the second clamping plate 402 is moved, the other clamping plate moves in the opposite direction.
[0091] The spraying operator can move the first clamp 401 or the second clamp 402 with one hand to clamp or release the component to be sprayed, freeing up one hand for positioning the component to be sprayed. This allows one spraying operator to position and clamp the component to be sprayed, greatly improving work efficiency and reducing labor costs.
[0092] The linkage structure includes: a first slide rail 403, a second slide rail 404, a first spring 405, and a second spring 406;
[0093] The first slide rail 403 and the second slide rail 404 are coaxially and movably connected, and the first slide rail 403 and the second slide rail 404 can rotate freely in a plane parallel to the spraying plane relative to their own center.
[0094] The first slide rail 403 is divided into two non-connected sliding areas by its center, and the second slide rail 404 is divided into two non-connected sliding areas by its center.
[0095] One end of the first spring 405 is placed in a sliding area of the first slide rail 403 and can move freely in the sliding area; at the same time, one end of the first spring 405 is fixedly connected to one end of the first clamping plate 401.
[0096] The other end of the first spring 405 is placed in a sliding area of the second slide rail 404 and can move freely in the sliding area; at the same time, the other end of the first spring 405 is fixedly connected to one end of the second clamping plate 402.
[0097] One end of the second spring 406 is placed in another sliding area of the first slide rail 403 and can move freely in that sliding area; at the same time, one end of the second spring 406 is fixedly connected to the other end of the first clamping plate 401.
[0098] The other end of the second spring 406 is placed in another sliding area of the second slide rail 404 and can move freely in that sliding area; at the same time, the other end of the second spring 406 is fixedly connected to the other end of the second clamping plate 402.
[0099] Taking the example of a spraying operator using one hand to control the displacement of the first clamping plate 401 to clamp or release the first clamping plate 401 and the second clamping plate 402 onto the component to be sprayed, as follows: Figure 2 As shown:
[0100] When preparing to clamp the spraying assembly, the spraying operator first controls the first clamping plate 401 with one hand to move it away from the second clamping plate 402. Simultaneously, one end of the first spring 405 and the second spring 406, which are fixedly connected to the first clamping plate 401, moves horizontally within the first horizontal slide groove 103 and the second horizontal slide groove 104, respectively, and slides within the corresponding sliding area of the first slide rail 403 or the second slide rail 404. This applies force to the first slide rail 403 or the second slide rail 404. Since the first spring 405 and the second spring 406 slide in different directions on the first slide rail 403 or the second slide rail 404... Therefore, the first slide rail 403 and the second slide rail 404 are subjected to different forces, which causes the first slide rail 403 to rotate counterclockwise and the second slide rail 404 to rotate clockwise. As a result, the first slide rail 403 and the second slide rail 404 exert a force on the other end of the first spring 405 and the second spring 406 that moves away from the first end of the spring. This causes the second clamping plate 402, which is fixedly connected to the other end of the first spring 405 and the second spring 406, to move away from the first clamping plate 401. A large displacement is left between the second clamping plate 402 and the first clamping plate 401, providing a space for the clamping of the component to be painted.
[0101] After the component to be painted is positioned, the painter uses their second hand to manually fix the component to be painted, while the first hand releases the first clamping plate 401. Under the tension of the first spring 405 and the second spring 406, the first slide rail 403 rotates clockwise and the second slide rail 404 rotates counterclockwise. The two ends of the first spring 405 and the two ends of the second spring 406 move towards each other, which drives the first clamping plate 401 and the second clamping plate 402 to move until their distance is just enough to clamp and engage the component to be painted, thus achieving the clamping and fixing of the component to be painted.
[0102] When preparing to release the component to be sprayed, the spraying operator first controls the first clamp 401 to move away from the second clamp 402 with one hand, the steps are the same as when preparing to clamp the component to be sprayed.
[0103] This invention features a first clamping plate and a second clamping plate with a linkage structure, such that when the first or second clamping plate is moved, the other clamping plate moves in the opposite direction. This allows the spraying operator to clamp or release the components to be sprayed by moving the first or second clamping plate with one hand, freeing up one hand for positioning the components. This enables a single spraying operator to position and clamp the components, greatly improving work efficiency and reducing labor costs.
[0104] The first clamping plate 401 and the second clamping plate 402 are detachable. The first clamping plate and the second clamping plate with different clamping surfaces are selected according to the different sides of the component to be sprayed.
[0105] This invention sets the first and second clamping plates as detachable structures, and matches the side of the component to be coated with the clamping surfaces of the first and second clamping plates, so that the clamping mechanism can adapt to components of different shapes and sizes to be coated, greatly expanding the types of components that can be processed for coating.
[0106] The angle adjustment mechanism 003 is equipped with a rotating shaft 307;
[0107] The spraying panel 001 includes a spraying plane 101, and two supporting side plates 102 are provided on opposite sides of the spraying plane 101.
[0108] The support structure 002 includes a bracket 201 and a base 202; there are two brackets 201, which are vertically fixed to the base 202 and are distributed on opposite sides of the base 202.
[0109] The rotating shaft 307 passes through the two supporting side plates 102 and is fixedly connected to the supporting side plates 102;
[0110] The two ends of the rotating shaft 307 are movably connected to the two supports 201, and can rotate freely relative to the supports 201 with its own axis as the center.
[0111] When the rotating shaft 307 rotates freely relative to the bracket 201, it can drive the spraying panel 001 to rotate coaxially, thereby realizing the adjustment of the angle of the spraying panel 001 relative to the horizontal plane, and thus realizing the adjustment of the spraying angle.
[0112] A ratchet 301 is provided at one end of the pivot 307 extending out of the bracket 201;
[0113] The angle adjustment mechanism 003 is also equipped with a pedal 302, a connecting rod 303, a first spring-loaded structure 304, and a pawl 306;
[0114] The fixed part of the pedal 302 is fixed to the base 202, and the moving part is fixedly connected to one end of the connecting rod 303; a first rebound structure 304 is provided between the fixed part and the moving part of the pedal 302, which is used to compress and store energy when the pedal 302 is subjected to pressure, and to restore the displacement of the fixed part and the moving part to the initial position after the pressure is released.
[0115] The other end of the connecting rod 303 is also provided with a pawl 306. When the ratchet 301 rotates to different angles, the pawl 306 can engage with it, so that the rotation angle of the ratchet 301 can be fixed, thereby fixing the angle between the spraying plane 101 and the plane at the target angle.
[0116] When the spraying operator steps on pedal 302, it causes the connecting rod 303 and pawl 306 to move downwards. Pawl 306 disengages from ratchet 301, allowing the spraying operator to adjust the angle of the spraying surface 101 relative to the horizontal plane by hand. Once the spraying surface 101 reaches the target position, the spraying operator releases the external force on pedal 302. Under the action of the first rebound structure 304, the moving part of pedal 302 causes the connecting rod 303 and pawl 306 to move upwards and reset, restoring the engagement and locking state of pawl 306 and ratchet 301, thereby fixing the angle of the spraying surface 101 relative to the horizontal plane.
[0117] This invention, through a ratchet, pedal, connecting rod, a first spring-loaded structure for pedal return, and a pawl for engaging the connecting rod, enables a single person, using one hand and one foot, to freely adjust the angle of the spraying plane relative to the horizontal plane. Compared to existing technologies that require at least two operators, this invention significantly reduces manpower and improves operational efficiency.
[0118] The ratchet 301 includes protrusions 3011 and recesses 3012 spaced apart, and the pawl 306 can engage and fix itself to the recesses 3012 between two adjacent protrusions 3011.
[0119] The other end of the connecting rod 303 is also provided with a second spring structure 305. One end of the second spring structure 305 is fixedly connected to the connecting rod 303, and the other end is fixedly connected to the bracket 201. When the pedal 302 is subjected to pressure, the second spring structure 305 stretches and stores energy. After the pressure on the pedal 302 is released, the second spring structure 305 assists the pawl 306 to engage with the recess 3012.
[0120] The base 202 is equipped with casters 203 at the bottom to facilitate the movement of the spraying device.
[0121] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
