Description

Technical Field

[0001] The utility model relates to the technical field of surface spraying of melamine impregnated paper, in particular to a surface spraying device for melamine impregnated paper. Background Art

[0002] Melamine-impregnated paper, also known as melamine-impregnated adhesive paper or "melamine" paper, is a specially treated decorative paper. It is made by impregnating plain base paper or printed decorative paper with amino resin (primarily melamine formaldehyde resin and urea-formaldehyde resin) and drying it to a certain degree to give it a certain resin content and volatile matter content. After heat pressing, this paper can be bonded to other materials such as artificial boards. It is widely used in decorative fields such as furniture and flooring. During the processing of melamine-impregnated paper, it needs to be sprayed.

[0003] For example, Chinese patent CN217856867U discloses a surface spraying device for melamine-impregnated paper. The device comprises a transmission structure, a movable frame, and a nozzle. The melamine-impregnated paper body is clamped by a clamping plate. The "U"-shaped movable frame moves back and forth on both sides of the melamine-impregnated paper body via the transmission structure, thereby spraying both sides of the melamine-impregnated paper body simultaneously. Two sides are sprayed at a time without manual flipping, achieving the effect of spraying both sides of the melamine-impregnated paper body at a time. Compared with the existing single-sided spraying, the spraying efficiency is greatly improved. The device comprises a screw rod, a movable block, and a clamping plate. The screw rod is rotated to drive the two clamping plates toward or away from each other, thereby clamping melamine-impregnated paper bodies of different sizes, thereby improving the actual use effect.

[0004] Although this structure can be used to spray melamine-impregnated paper, the nozzle can only spray in a reciprocating motion, and it is inconvenient for the nozzle to spray in a sweeping manner, resulting in poor spraying effect. Therefore, we propose a surface spraying device for melamine-impregnated paper that can perform sweeping spraying to make the spraying more uniform and improve the spraying effect of melamine-impregnated paper.

[0009] Preferably, the end of the square rod is set in an arc surface, and the outer wall of the protrusion is set in an arc surface. Under their restriction, when the square rod and the protrusion are squeezed, the square rod drives the connecting pipe and the spray plate to move up and down, thereby expanding the spraying range.

[0010] Preferably, the connecting pipe is a hard pipe body, the outer wall of the connecting pipe is fixedly installed inside the square rod, and the delivery pipe is a soft pipe body.

Under the restriction of the support plate 442, the push rod 440 compresses the spring 441 sleeved on its outer wall, so that the push rod 440 pushes the push block 439, and the push block 439 pushes the clamping plate 437 through the connecting plate 438, so that the sliding rod 436 fixedly installed on the outer wall of the clamping plate 437 slides inside the fixed block 435, so that the two clamping plates 437 move in opposite directions. At this time, the melamine-impregnated paper body 3 is placed on the inner side of the clamping plate 437, and the push rod 440 is released. Under the elastic action of the spring 441, the push rod 440 is pushed The push rod 440 drives the push block 439 to move upward, so that the push block 439 pulls the clamping plate 437 through the connecting plate 438, so that the sliding rod 436 fixedly installed on the outer wall of the clamping plate 437 slides inside the fixed block 435, and the two clamping plates 437 move in opposite directions to clamp the melamine-impregnated paper body 3, clamping the two ends of the melamine-impregnated paper body 3.
