Technical Field

[0001] The utility model relates to the technical field of impregnated paper, in particular to a formaldehyde detection mechanism for low-formaldehyde impregnated paper. Background Art

[0002] Impregnated paper, also known as "melamine" paper, is a kind of plain base paper or printed decorative paper that has been impregnated with amino resin (melamine formaldehyde resin and urea-formaldehyde resin) and dried to a certain degree. It has a certain resin content and volatile content. It can be glued to each other or to the artificial board substrate by hot pressing.

[0003] After the production of impregnated paper is completed, it is necessary to conduct formaldehyde testing on the impregnated paper to avoid the formaldehyde content of the impregnated paper being too high and not meeting environmental protection standards.

[0004] To this end, we proposed a low-formaldehyde impregnated paper formaldehyde testing agency to solve the above problems. Utility Model Content

[0007] The bottom of the linkage plate is fixedly connected to two groups of connection shells, and the inner cavities of the connection shells are fixedly connected to springs, and the other ends of the springs are fixedly connected to linkage rods, and the bottom ends of the two groups of linkage rods are fixedly connected to fixed plates;

[0008] The surface of the recovery shell is fixedly connected with a guide shell, the surface of the guide shell is fixedly connected with a breathable plate, and the surface of the breathable plate is fixedly connected with an air suction pump, and a recovery box is arranged under the guide shell.

[0009] Preferably, a guide shell is fixedly connected to the surface of the guide shell, a plurality of second electric telescopic rods are fixedly connected to the inner wall of the guide shell, and a push plate is fixedly connected to the bottom of the plurality of second electric telescopic rods.

[0010] Preferably, the fixing plate is made of rubber material.

[0011] Preferably, a protrusion for supporting the suction pump is provided on the top of the recovery box.

[0012] Preferably, the fixing plate is horizontally parallel to the conveyor belt.

[0013] Preferably, the recovery shell is arranged in an eight-shaped shape.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] While the first electric telescopic rod pushes the linkage plate to move downward, the linkage plate also drives the cutting blade to move downward to cut the impregnated paper. When the formaldehyde detected by the formaldehyde detector returns to normal, the first electric telescopic rod starts again, pushing the linkage plate to drive the cutting blade to cut the impregnated paper again, and removing the part with excessive formaldehyde. This solves the problem of needing to conduct formaldehyde testing on the impregnated paper after the production of the impregnated paper is completed, to avoid the problem of too high formaldehyde content in the impregnated paper that does not meet environmental protection standards.

DETAILED DESCRIPTION

[0021] 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.

[0022] See also Figure 1-4The utility model provides a technical solution: a formaldehyde detection mechanism for low-formaldehyde impregnated paper, comprising a conveyor belt 1 and a detection shell 2 fixedly connected to the top of the conveyor belt 1, the conveyor belt 1 is used to transport the impregnated paper after production, when the impregnated paper passes through the detection shell 2, the formaldehyde content of the impregnated paper is detected by a formaldehyde detector 3, when the formaldehyde value is too high, an alarm is sounded to start the first electric telescopic rod 4, the first electric telescopic rod 4 pushes the linkage plate 5 to move downward, and the linkage plate 5 also drives the cutting blade 6 to move downward to cut the impregnated paper, when the formaldehyde detected by the formaldehyde detector 3 returns to normal, the first electric telescopic rod 4 is started again, pushing the linkage plate 5 to drive the cutting blade 6 to cut the impregnated paper again, and the part with excessive formaldehyde is removed.

[0023] For details, please refer to Figure 1-4 When the linkage plate 5 moves downward, it first drives the connecting shell 7, the linkage rod 9 and the fixed plate 10 to contact the impregnated paper. The linkage rod 9 is connected to the connecting shell 7 through the spring 8 with a certain elastic space, ensuring that the fixed plate 10 can press the impregnated paper tightly while also preventing the fixed plate 10 from exerting too much pressure on the conveyor belt 1. The fixed plate 10 presses and fixes the impregnated paper to prevent the cutting blade 6 from sliding when cutting.

[0024] For details, please refer to Figure 1-4 After the cutting of the impregnated paper is completed, the suction pump 14 is started to suck the cut impregnated paper into the guide shell 12 through the recovery shell 11. The air permeable plate 13 protects the suction pump 14 to prevent the suction pump 14 from being blocked. The sucked waste impregnated paper is discharged into the recovery box 15 for collection under the guidance of the guide shell 12. When too much impregnated paper blocks the guide shell 12, the multiple second electric telescopic rods 17 in the dredging shell 16 are started, and the multiple second electric telescopic rods 17 push the push plate 18 to dredge the guide shell 12.

[0025] Working principle: The impregnated paper after production is transported by the conveyor belt 1. When the impregnated paper passes through the detection shell 2, the formaldehyde content of the impregnated paper is detected by the formaldehyde detector 3. When the formaldehyde content is too high, an alarm is sounded to start the first electric telescopic rod 4. While the first electric telescopic rod 4 pushes the linkage plate 5 to move downward, the linkage plate 5 also drives the cutting blade 6 to move downward to cut the impregnated paper. When the formaldehyde detected by the formaldehyde detector 3 returns to normal, the first electric telescopic rod 4 is started again, pushing the linkage plate 5 to drive the cutting blade 6 to cut the impregnated paper again, and the part with excessive formaldehyde is removed. When the linkage plate 5 moves downward, it first drives the connecting shell 7, the linkage rod 9 and the fixed plate 10 to contact the impregnated paper first. The linkage rod 9 is connected to the connecting shell 7 by the spring 8 with a certain elastic space to ensure that the fixed plate 10 can The impregnated paper is pressed tightly and at the same time, it also prevents the fixed plate 10 from exerting too much pressure on the conveyor belt 1. The fixed plate 10 presses and fixes the impregnated paper to prevent the cutting blade 6 from sliding when cutting. After the impregnated paper is cut, the suction pump 14 is started to suck the cut impregnated paper into the guide shell 12 through the recovery shell 11. The air-permeable plate 13 protects the suction pump 14 to prevent the suction pump 14 from being blocked. The sucked waste impregnated paper is discharged into the recycling box 15 for collection under the guidance of the guide shell 12. When too much impregnated paper blocks the guide shell 12, the multiple second electric telescopic rods 17 in the dredging shell 16 are started, and the multiple second electric telescopic rods 17 push the push plate 18 to dredge the guide shell 12, which solves the problem that the impregnated paper needs to be tested for formaldehyde after the production of the impregnated paper is completed, so as to avoid the problem that the formaldehyde content of the impregnated paper is too high and does not meet the environmental protection standards.
