Abstract
Description
Technical Field
[0001] This utility model relates to the field of impregnated paper technology, and in particular to a formaldehyde detection device for impregnated paper production. Background Technology
[0002] After the impregnated paper is produced, the formaldehyde content needs to be tested to see if it meets the factory standards. The general testing method is to stack multiple layers of impregnated paper and put them in a sealed testing chamber to simulate a high-density loading environment. Under limited ventilation conditions, the formaldehyde release may increase significantly due to the cumulative effect.
[0003] However, this testing environment cannot simulate the indoor environment after the impregnated paper is laid. Conducting tests is closer to actual living conditions and reflects the formaldehyde concentration that users are exposed to on a daily basis. Utility Model Content
[0004] The purpose of this application is to provide a formaldehyde detection device for impregnated paper production to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this application provides the following technical solution: A formaldehyde detection device for impregnated paper production includes a housing and a detection assembly installed inside the housing. The detection assembly includes a mounting rod, a fixed rod, and a movable rod. The mounting rod is movably installed inside the housing. Multiple fixed and movable rods are arranged alternately below the mounting rod, with the edges of each fixed and movable rod abutting against each other. One end of each fixed rod is fixedly connected to the bottom surface of the mounting rod, and the ends of each movable rod are movably connected to the fixed rod. A mesh plate is fixedly installed on the lower inner wall of the housing, and a limit plate is fixedly installed above the mesh plate. Multiple detection tubes are fixedly installed on the outer side wall of the housing, and each detection tube is fitted with multiple fan-shaped adhesive blocks whose edges abut against each other for sealing.
[0006] Preferably, multiple electromagnets are embedded inside the mounting rod, the number and installation position of which correspond to the moving rod. The end of the moving rod has a slot, the shape of which is adapted to the electromagnet. The fixing rod of the moving rod is made of ferrous metal. Multiple slotted plates are fixedly installed on one inner wall of the housing. Guide slots are formed inside the slotted plates, the number and installation position of which correspond to the fixing rod and the moving rod. A guide block is fixedly installed at one end of both the fixing rod and the moving rod, and the guide block is embedded inside the guide slot of the slotted plate.
[0007] Preferably, both ends of the limiting plate are equipped with screws via bearings. The screws are vertically mounted on the limiting plate, and a motor is mounted at the top of the screw. The motor is fixedly mounted on the inner side wall of the housing, and the screw is driven by the motor. Both ends of the mounting rod are fixedly mounted with sliders, and the sliders are threadedly connected to the screw.
[0008] The beneficial effects of this invention are: by setting up a detection component, stacking and unfolding tests can be performed simultaneously to detect the formaldehyde concentration of impregnated paper under two conditions, providing two sets of data for comparison and improving the accuracy of the detection data.

[0012] like Figure 1-3 The formaldehyde detection device for impregnated paper production shown includes a housing 1 and a detection assembly installed inside the housing 1. The detection assembly includes a mounting rod 5, a fixed rod 3, and a movable rod 4. The mounting rod 5 is movably installed inside the housing 1. Multiple fixed rods 3 and movable rods 4 are arranged alternately below the mounting rod 5, with the edges of each fixed rod 3 and movable rod 4 fitting together. One end of each fixed rod 3 is fixedly connected to the bottom surface of the mounting rod 5, and the ends of each movable rod 4 are movably connected to the fixed rod 3. A mesh plate 2 is fixedly installed on the lower inner wall of the housing 1, and a limit plate 7 is fixedly installed above the mesh plate 2. Multiple detection tubes are fixedly installed on the outer side wall of the housing 1, and multiple fan-shaped adhesive blocks are installed on the detection tubes. The edges of the fan-shaped adhesive blocks fit together to provide a sealing effect.
[0013] Multiple electromagnets 6 are embedded inside the mounting rod 5. The number and installation position of the multiple electromagnets 6 correspond to the moving rod 4. The end of the moving rod 4 has a slot 8, the shape of which is adapted to the electromagnet 6. The fixing rod 3 of the moving rod 4 is made of iron metal. Multiple slot plates 11 are fixedly installed on one side inner wall of the housing 1. The slot plates 11 have guide grooves inside. The number and installation position of the multiple slot plates 11 correspond to the fixing rod 3 and the moving rod 4. A guide block is fixedly installed at one end of both the fixing rod 3 and the moving rod 4. The guide block is embedded in the guide groove of the slot plate 11.
[0014] Both ends of the limiting plate 7 are equipped with screws 10 via bearings. The screws 10 are vertically mounted on the limiting plate 7. A motor 9 is mounted on the top of the screw 10. The motor 9 is fixedly mounted on the inner side wall of the housing 1. The screw 10 is driven by the motor 9. Both ends of the mounting rod 5 are fixedly mounted with sliders 12. The sliders 12 are threadedly connected to the screws 10.
[0015] Example: Open the door panel of the chamber 1, place the stacked experimental impregnated paper on the mesh plate 2, then start the motor 9. The motor 9 drives the screw 10 to rotate, the screw 10 drives the slider 12, and the slider 12 drives the mounting rod 5 to move towards the limiting plate 7. The electromagnet 6 is energized and its on / off state is controlled by the internal electrical control terminal of the chamber 1. The electromagnet 6 is engaged and attracted with the slot 8 of the moving rod 4. The mounting rod 5 drives the fixed rod 3 and the moving rod 4 to move. The ends of the fixed rod 3 and the moving rod 4 slide on the slot plate 11, so that the fixed rod 3 and the moving rod 4 are in contact with the upper surface of the limiting plate 7, so that the area of the chamber 1 below the limiting plate 7 forms a closed space, simulating a high-density loading environment, and testing the formaldehyde release under this environment.
[0016] The sample is laid flat or placed in a single layer to simulate a real-world usage scenario (such as an indoor environment after installation). The electromagnet 6 can be de-energized. After de-energization, the moving rod 4 stops on the limiting plate 7. Then, the motor 9 starts, driving the screw 10 to rotate. The screw 10 drives the mounting rod 5 to rise, and the mounting rod 5 drives the fixing rod 3 to rise. At this time, there is space between the multiple fixing rods 3. The operator can place the entire sheet of impregnated paper in a wavy shape on the fixing rods 3, so that a large area of the impregnated paper is exposed to the air, and the formaldehyde content in this environment can be tested.
