Description

Technical Field

[0001] The utility model relates to the technical field of composite board waterproof coating spraying, in particular to a moisture-proof composite board surface coating spraying device. Background Art

[0002] Composite panels are generally made of two or more wooden panels. Due to the different properties of each layer, the moisture absorption deformation index varies greatly during use. Therefore, spraying a moisture-proof coating on the surface of the panel is an important step in the processing of composite panels. After the moisture-proof coating is applied, the panel can maintain its performance and appearance in a humid environment. The spraying device used in this process generally adopts an axially moving reciprocating sprayer, and its core function is: the movement of the linear belt drives the spray gun to move back and forth to implement the spraying operation.

[0003] In the prior art, the outer shell of a reciprocating sprayer needs to be provided with an axial guide rail or slide groove for movement to achieve internal and external connectivity of the sprayer. During the spraying process, particles of the sprayed waterproof layer will enter the interior of the outer shell through the guide rail or slide groove. As the use time increases, the particles inside the outer shell accumulate, which will inevitably lead to increased wear or instability during the transmission process, ultimately affecting the operation quality and equipment life.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1 to Figure 6 In an embodiment of the utility model, a surface coating spraying device for a moisture-proof composite board material comprises a shell having a front end plate 1, a sliding groove 2 is transversely opened inside the front end plate 1, two synchronous wheels 10 are rotatably installed inside the shell, and the two synchronous wheels 10 are connected by a linear belt 7; the linear belt 7 is connected to a connecting plate 3 through a mounting mechanism, and the mounting mechanism is slidably connected to the sliding groove 2; a shielding mechanism is distributed on the inner wall of the front end plate 1, and the shielding mechanism in the reset state is used to shield the sliding groove 2 to prevent the spraying material from entering the inner cavity of the shell through the sliding groove 2.

[0022] In this embodiment: the moisture-proof spraying of the plate is generally performed by spraying a waterproof layer through a spray gun 6. When a driving motor drives a synchronous wheel 10 to rotate, the synchronous wheel 10 drives another synchronous wheel 10 to rotate synchronously through a linear belt 7. During the transmission process of the linear belt 7, the linear belt 7 drives the spray gun 6 to move back and forth through the mounting mechanism, and cooperates with the plate moving on the conveyor belt. The moving direction of the plate is perpendicular to the moving direction of the spray gun 6, so that the waterproof layer can be sprayed on the upward side of the plate.

[0023] During the transmission process of the linear belt 7, the linear belt 7 drives the installation mechanism to move back and forth along the sliding groove 2. The reciprocating installation mechanism continuously contacts with multiple shielding mechanisms arranged along the extension direction of the sliding groove 2. The shielding mechanism in contact with the installation mechanism moves upward without interfering with the movement of the installation mechanism. The shielding mechanism that is misaligned with the installation mechanism is reset, which can block the opening of the sliding groove 2 located on the inner side of the front end plate 1 to prevent the sprayed waterproof layer particles from entering the interior of the outer shell.

[0024] Please refer to Figure 3 , Figure 4 and Figure 5 The installation mechanism includes an upper clamping plate 11 distributed at the top end of the upper half of the linear belt 7 and a lower clamping plate 12 distributed at the bottom end of the upper half of the linear belt 7. The top of the lower clamping plate 12 is integrally formed with a stud that penetrates to the top of the upper clamping plate 11. A nut is tightened on the outer wall of the stud, and a through hole corresponding to the stud is opened on the linear belt 7; the installation mechanism also includes a connecting piece 9 integrally formed at one end of the upper clamping plate 11, and the connecting piece 9 is slidably connected to the inner cavity of the sliding groove 2.

[0025] In this embodiment, during the transmission process of the linear belt 7 , the linear belt 7 drives the upper clamping plate 11 and the lower clamping plate 12 to move synchronously, and the moving upper clamping plate 11 and the lower clamping plate 12 drive the connecting piece 9 to slide along the sliding groove 2 .

[0026] Please refer to Figure 1 , Figure 2 and Figure 3 One end of the connecting piece 9 is located outside the front end plate 1 and is fixedly connected to a connecting plate 3. A rotating head 5 is rotatably installed at one end of the connecting plate 3. A spray gun 6 is clamped in the inner wall of the annular part of the rotating head 5. A locking bolt 4 for limiting the rotating head 5 is threadedly connected to one side of the connecting plate 3.

[0027] In this embodiment: when the connecting piece 9 slides along the sliding groove 2, the connecting piece 9 drives the connecting plate 3 to move synchronously, and the connecting plate 3 drives the spray gun 6 to reciprocate through the rotating head 5. After the spray gun 6 is started, reciprocating spraying can be performed;

[0028] Before spraying, the angle of the spray gun 6 is adjusted, specifically by rotating the rotating head 5. After the rotating head 5 has rotated completely, the locking bolt 4 is tightened. At this time, the end of the locking bolt 4 effectively abuts against the outside of the rotating head 5, thereby limiting the position of the rotating head 5.

[0029] Please refer to Figure 5 and Figure 6 The shielding mechanism includes a fixed block 16 fixedly connected to the inner wall of the front end plate 1, a movable column 17 is slidably connected to the inside of the fixed block 16, a baffle 14 is fixedly connected to the bottom end of the movable column 17, and the top center of the baffle 14 and the bottom center of the fixed block 16 are fixedly connected to the two ends of the spring 8; the two sides of the lower half of the baffle 14 are formed with compression slopes 15, and the two sides of the upper clamping plate 11 are formed with extrusion slopes 13 that match the compression slopes 15.

[0030] In this embodiment: when the upper clamping plate 11 moves along with the linear belt 7, the extrusion slope 13 of the upper clamping plate 11 contacts the pressure slope 15 of the baffle 14. At this time, the baffle 14 is forced to move upward, and the baffle 14 drives the moving column 17 to move upward. During this process, the spring 8 is compressed. In the above process, the shielding mechanism does not interfere with the movement of the upper clamping plate 11.

[0031] When the upper clamping plate 11 is misaligned with the shielding mechanism, the spring 8 is reset to drive the shielding plate 14 to move downward. At this time, the shielding plate 14 shields the inner opening of the sliding groove 2 to prevent the force of the waterproof coating from entering the interior of the housing.

[0032] Please refer to Figure 6 The lower half of the baffle 14 in the reset state blocks the opening of the sliding slot 2 located on the inner side of the front end plate 1, and a rubber pad is fixedly connected to the inner contact surface of the baffle 14 and the front end plate 1 by adhesive glue.

[0033] In this embodiment: the rubber pad can further reduce the gap between the baffle plate 14 and the front end plate 1, thereby further improving the shielding effect of the shielding mechanism.

[0034] Please refer to Figure 6 A sliding hole is provided inside the fixed block 16 for the moving column 17 to move up and down. The inner diameter of the sliding hole is equal to the diameter of the moving column 17, and an anti-slip portion is formed on the top of the moving column 17, and the diameter of the anti-slip portion is larger than the diameter of the moving column 17.

[0035] In this embodiment, the provision of the anti-slip portion can prevent the movable column 17 from being separated from the sliding hole.

[0036] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
