Description

Technical Field

[0001] This utility model belongs to the field of fire door processing technology, and in particular relates to an adhesive coating device for producing fire doors. Background Technology

[0002] Fire doors, as the name suggests, are fire-resistant partitions. To ensure their function, fire doors are generally made of multi-layer boards. To facilitate the processing of multi-layer boards, an adhesive spraying device is usually used to automatically apply adhesive to the boards.

[0003] An existing document with publication number CN222093811U discloses an automatic coating device for rectangular sheet metal, including a frame, a gantry frame mounted on top of the frame, and a coating assembly mounted on the gantry frame. The coating assembly includes a moving module, with a coating rack at the moving end. Each side of the coating rack has an adhesive storage pipe, with a one-way valve on the outside of the pipe and an adhesive dispensing valve at the bottom. The bottom of the storage pipe is connected to a module, and the bottom of the module is an adhesive dispensing module with multiple adhesive dispensing holes arranged in a straight line. In this designed coating assembly, the drive shaft on the frame is responsible for stably conveying the sheet metal.

[0004] However, it still has the following drawbacks in practical use:

[0005] 1. The automatic spraying device mentioned above includes a moving module, a connecting module, and a glue dispensing module, etc. The moving module drives the board to move, and the glue dispensing module sprays glue onto the board. However, during use, it is not convenient to automatically clean the board, as dust and other debris adhering to the board affect the glue spraying effect.

[0006] 2. The automatic spraying device mentioned above includes a moving module, a connecting module, and a glue dispensing module, etc. The moving module drives the board to move, and the glue dispensing module sprays glue onto the board. However, during use, it lacks a structure to limit the board during feeding to prevent the board from shifting during the glue application process and affecting the glue spraying effect.

[0007] To address these issues, we provide an adhesive coating apparatus for producing fire doors. Utility Model Content

[0047] Example 2

[0048] Please see Figure 1 , Figure 9 , Figure 10 , Figure 11 , Figure 12 and Figure 13As shown, this is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but differs from the previous embodiment in that: a dust removal component 5 is also provided on one side of the spray frame 1. The dust removal component 5 includes a mounting frame 501, a mounting plate 502, a cleaning disc 503, a third drive motor 504, and a dust collection hood 505. The third drive motor 504 drives the cleaning disc 503 and the brush 503b to clean the dust on the surface of the board, and the dust collection hood 505 collects the dust, thus solving the problem that it is inconvenient to clean the glued board.

[0049] Specifically, there are two mounting frames 501, which are fixedly connected to the front and rear ends of the feed side of the transport frame 2 respectively. The mounting frames 501 are movably connected to the mounting plate 502. Multiple rotating shafts 503a are rotatably connected to the surface of the mounting plate 502 along the longitudinal direction at equal intervals. A cleaning disc 503 is fixedly connected to the bottom end of each rotating shaft 503a. A brush 503b is fixedly connected to the bottom of the cleaning disc 503. A driven gear 503c is fixedly connected to the top end of each rotating shaft 503a. A transmission gear 502b meshes between the driven gears 503c. The transmission gear 502b is rotatably connected to the upper surface of the mounting plate 502. A third drive motor 504 is fixedly connected to the front end of the upper surface of the mounting plate 502 through a third motor frame 504a. The output shaft of the third drive motor 504 is sleeved with a drive gear 504b. A dust collection cover 505 is fixedly connected to one side of the mounting plate 502.

[0050] Furthermore, the mounting frame 501 is internally rotatably connected to a threaded rod 501a, and a third slider 502a is threadedly sleeved on the outer wall of the threaded rod 501a. The end of the third slider 502a located on the outside of the mounting frame 501 is fixedly connected to the front and rear end faces of the mounting plate 502.

Fixing rods 505a are fixedly connected to the front and rear ends of the dust collection hood 505. The end of the fixing rod 505a away from the dust collection hood 505 passes through the L-shaped frame 502c and is threaded with a fastening nut 505b. The top of the dust collection hood 505 is fixedly connected to the dust collection pipe 505c.

[0053] The rest of the structure is the same as in Example 1.

[0054] The operation process of this embodiment is as follows: The handwheel 501b is rotated, causing the threaded rod 501a to rotate synchronously. The threaded rod 501a, through the third slider 502a, causes the mounting plate 502 to rise and fall, so that the brush 503b at the bottom of the cleaning disc 503 contacts the upper surface of the board. Then, the third drive motor 504 is started. The output shaft of the third drive motor 504 drives the drive gear 504b to rotate. Combined with the transmission action of the transmission gear 502b, the rotating shaft 503a drives the cleaning disc 503 and the brush 503b to move. The brush 503b cleans the dust on the board. At the same time, the dust collection hood 505 is connected to a dust removal fan through the dust collection pipe 505c, and the dust is collected by the dust collection hood 505, thus realizing automatic cleaning of the board to be glued.
