[0002] Film coating is an advanced surface treatment technology that can achieve a smooth, continuous and uniform coating by evenly coating the surface of the workpiece with liquid coating.

[0003] In the prior art, in order to improve the efficiency of laminating coating, a belt conveyor is usually used to continuously convey the plates to the bottom of the laminating head for coating; this method can ensure that the plates pass through the laminating area smoothly and efficiently, thereby improving the speed and production capacity of the entire coating process.

[0004] However, the above-mentioned belt conveyor still has the following defects during use:

[0005] At present, when the existing spraying device is coating the plate, the angle of the coating head is fixed; however, in the process of using the belt to convey the plate, due to the weight of the plate, it is difficult to ensure that the belt always maintains sufficient tension, so that the plate cannot be completely kept in a horizontal state during the transportation process; when the plate passes under the coating head in a non-horizontal state, the dripping paint will flow to one side under the action of gravity, resulting in uneven coating thickness, affecting the uniformity and appearance quality of the final coating.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] like Figure 1-8 As shown, a coating equipment for a plate, such as Figure 1-4 As shown, it includes a coating head 2 and a belt conveyor mechanism 4 arranged on the chassis 1; the belt conveyor mechanism 4 is used to convey the plate 3 to the bottom of the coating head 2 for coating; a leveling mechanism 5 is arranged on the belt conveyor mechanism 4, and the leveling mechanism 5 includes: a synchronous conveying mechanism 51, which is arranged on the belt conveyor mechanism 4; the synchronous conveying mechanism 51 is used to position the plate 3 on the belt conveyor mechanism 4, so that the plate 3 is conveyed along the transmission direction of the belt conveyor mechanism 4; a distance sensor 52, which is arranged on the coating head 2; the distance sensor 52 is used to detect the distance between the plate 3 and the distance sensor 52; and an angle adjustment mechanism 53, which is arranged on the synchronous conveying mechanism 51; the angle adjustment mechanism 53 is used to adjust the conveying angle of the plate 3, so that the coated surface of the plate 3 is kept horizontal during transportation.

[0036] It should be noted that the plate 3 is positioned on the belt conveyor mechanism 4 and transported synchronously through the synchronous conveying mechanism 51, thereby improving the stability of the conveying of the plate 3; when the plate 3 is transported in a horizontal state, the distance data detected by the distance sensor 52 changes with the conveying speed of the belt conveyor mechanism 4; when the plate 3 is in an inclined state, the data detected by the distance sensor 52 will change. At this time, the plate 3 is driven to rotate through the angle adjustment mechanism 53, so that the plate 3 maintains a horizontal state and is transported to the bottom of the laminating head 2, thereby ensuring the laminating coating effect of the laminating head 2.

[0037] like Figure 1-3 As shown, the synchronous conveying mechanism 51 includes a plurality of positioning bars 511; the plurality of positioning bars 511 are arranged at equal intervals on the belt of the belt conveying mechanism 4; and the distance between adjacent positioning bars 511 is greater than the width of the plate 3; it should be noted that by setting a plurality of positioning bars 511, when the plate 3 is placed on the belt conveying mechanism 4, the plate 3 can be initially positioned, and then the synchronous conveying mechanism 51 can be used to further position the plate 3, thereby improving the conveying stability of the plate 3 and further improving the coating effect.

[0038] like Figure 1-4 As shown, the synchronous conveying mechanism 51 also includes a pair of motors 512, a screw 513, a threaded seat 514 and a clamping mechanism 515; the pair of motors 512 are installed on the belt conveying mechanism 4, the pair of screws 513 are arranged on the belt conveying mechanism 4 in parallel along the conveying direction of the belt conveying mechanism 4, and the output end of the motor 512 is coaxially connected with the screw 513; the pair of threaded seats 514 are respectively threadedly connected to the pair of screws 513; the pair of clamping mechanisms 515 are respectively arranged on the pair of threaded seats 514; the pair of clamping mechanisms 515 are used to clamp the plate 3.

[0039] It should be noted that the screw rod 513 is driven to rotate by the motor 512, and the screw rod 513 drives the threaded seat 514 to move, thereby driving the plate 3 clamped by the clamping mechanism 515 to move synchronously with the belt conveyor mechanism 4, thereby improving the stability of the plate 3 in being transported on the belt conveyor mechanism 4; when the plate 3 is placed between the two positioning bars 511, the motor 512 is not started first, and the plate 3 is moved with the transmission of the belt conveyor mechanism 4 until the plate 3 moves between the two clamping mechanisms 515, and the two clamping mechanisms 515 automatically clamp and position the plate 3, and then the motor 512 is started to achieve the purpose of synchronous positioning and transportation; and when the coating is completed, the clamping mechanism 515 is driven by the motor 512 to move and reset, so that the next plate 3 is clamped by the clamping mechanism 515, and such a cyclic movement is achieved to achieve the purpose of continuously positioning, clamping and synchronously conveying multiple plates 3, thereby improving the efficiency of coating.

[0040] like Figure 4-5 As shown, the clamping mechanism 515 includes a connecting rod 5151, a rotating rod 5153 and a clamping wheel 5154; the connecting rod 5151 is arranged on the threaded seat 514, one end of the rotating rod 5153 is hinged to the connecting rod 5151, and the connecting rod 5151 is provided with a torsion spring connected to the rotating rod 5153, and the clamping wheel 5154 is rotatably connected to the rotating rod 5153; it can be understood that the clamping wheel 5154 is coated with a rubber layer; the clamping wheel 5154 directly contacts and clamps the plate 3 through the rubber layer, which can reduce the problem of excessive clamping and deformation of the plate 3 affecting the coating.

[0041] It should be noted that when the belt conveyor mechanism 4 drives the plate 3 to move, the plate 3 moves between the clamping wheels 5154, and the clamping wheels 5154 clamp and position the plate 3 through the action of the torsion spring; after the coating of the plate 3 is completed, the clamping mechanism 515 is directly driven to move in the opposite direction, so that the clamping wheels 5154 roll along the side wall of the plate 3 and are staggered with the plate 3, so as to facilitate the clamping of the next plate 3; and the plate 3 that has completed the coating is transported by the belt conveyor mechanism 4 with the cooperation of the positioning strip 511, thereby improving the convenience of use.

[0042] like Figure 4-5 As shown, the clamping mechanism 515 further includes a connecting shaft 5152 ; the connecting shaft 5152 is slidably connected to the connecting rod 5151 along its axis; a first compression spring 5155 connected to the connecting rod 5151 is sleeved on the connecting shaft 5152 .

[0043] It should be noted that when the plate 3 is placed between the two positioning bars 511, that is, in an inclined state, as the clamping wheel 5154 clamps the plate 3, the clamping wheel 5154 will move obliquely along the side of the plate 3 to maintain effective clamping of the side of the plate 3; at the same time, the first compression spring 5155 will push the plate 3 to rotate and reset, so that the plate 3 is close to a horizontal state, which is conducive to the coating work.

[0044] like Figure 1-2 and Figure 4-8 As shown, the angle adjustment mechanism 53 includes a mounting seat 531, a pair of first cams 532, a second cam 533 and a driving mechanism 534; the connecting rod 5151 is rotatably connected to the threaded seat 514 by a coaxial pin; the mounting seat 531 is fixed to the threaded seat 514, a pair of first cams 532 are rotatably connected to the mounting seat 531 around their axes, and a pair of second cams 533 are rotatably connected to the connecting rod 5151 around their axes; the first cam 532 is in conflict with the second cam 533, and the contact surfaces of the first cam 532 and the second cam 533 are adapted; and when the connecting rod 5151 and the mounting seat 531 are in a parallel state, the axes of the first cam 532 and the second cam 533 coincide.

[0045] When the plate 3 is in an inclined state, the driving mechanism 534 drives the first cam 532 to rotate, and cooperates with the action of the second cam 533 to rotate the connecting rod 5151, thereby driving the plate 3 to adjust its angle, until the distance measuring sensor 52 detects that the distance between the plate 3 and it reaches the standard distance required when the belt conveyor mechanism 4 conveys the plate 3, that is, the plate 3 is restored to a horizontal state, which is convenient for subsequent coating operations; the distance change when the belt conveyor mechanism 4 drives the plate 3 to be conveyed here means that when the belt conveyor mechanism 4 conveys the plate 3 at a constant speed, the distance measuring sensor 52 detects that the distance between the plates 3 will show regular changes; if the distance change detected by the distance measuring sensor 52 deviates from this rule, it indicates that the plate 3 is in an inclined state and an angle adjustment is required.

[0046] like Figure 7-8 As shown, both the first cam 532 and the second cam 533 are provided with a protrusion and a recess; the protrusion on the first cam 532 is matched with the recess on the second cam 533, and the recess on the first cam 532 is matched with the protrusion on the second cam 533; and a rounded transition is used between the protrusion and the recess.

[0047] It should be noted that when the first cam 532 is driven to rotate, the protrusion on the first cam 532 and the recess on the second cam 533 are misaligned, which will push the connecting rod 5151 to rotate, thereby driving the plate 3 to rotate to a horizontal state.

[0048] like Figure 1-8 As shown, it can be understood that the present application does not limit the specific structure and installation method of the driving mechanism 534, and only provides a feasible technical solution below; the driving mechanism 534 includes an electric push rod 5341 and a rack 5342; the electric push rod 5341 is installed on the mounting seat 531, the rack 5342 is arranged at the output end of the mounting seat 531, and the first cam 532 is provided with a tooth groove 5343 that meshes with the rack 5342.

[0049] It should be noted that the rack 5342 is driven to move by the electric push rod 5341, and with the cooperation of the tooth groove 5343, the first cam 532 is driven to rotate, and then the connecting rod 5151 is driven to rotate, so as to achieve the purpose of adjusting the inclination angle of the plate 3.

[0050] like Figure 1-2 and Figure 4-8 As shown, the angle adjustment mechanism 53 also includes a slider 535; a slide groove 536 is provided on the threaded seat 514, the slider 535 is slidably connected to the slide groove 536, the connecting rod 5151 is rotationally connected to the slider 535 through a pin shaft, and a second compression spring 537 connected to the slider 535 is provided in the slide groove 536.

[0051] It should be noted that, in the process of coating the plate 3, the rack 5342 is driven to move by the electric push rod 5341, and with the cooperation of the second compression spring 537, the connecting rod 5151 is driven to move up and down, which will drive the plate 3 to vibrate up and down in a horizontal state, so that the coating slurry is vibrated more evenly, thereby improving the coating effect. At the same time, the vibration of the slurry can break the bubbles in the slurry, further improving the coating effect.

In addition, "first" and "second" are only for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0053] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", etc. should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0054] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
