Description

Technical Field

[0001] This utility model relates to the field of polystyrene board technology, and in particular to a flame retardant performance testing device for polystyrene board production. Background Technology

[0002] Polystyrene boards are flammable and produce toxic fumes when burned, so flame retardants need to be added during the production process to improve their fire resistance.

[0003] To ensure the safety of the polystyrene boards during transportation and use, a flame retardancy test is conducted after production. Operators ignite waste materials from the production line and observe the burning behavior. However, this process is often performed without protective gear, with the boards directly ignited in the waste area of ​​the production line. If the boards lack sufficient flame retardancy and produce a noticeable flame, the safety of the test cannot be guaranteed. Utility Model Content

[0015] like Figure 1-3The device shown is a flame retardant performance testing device for polystyrene board production, comprising a belt conveyor and a testing assembly. The belt conveyor includes a conveyor belt 1 and two mounting plates 2, with the conveyor belt 1 installed between the two mounting plates 2. The testing assembly includes a blade 3, an observation chamber 8, a gas pipe 9, and a water pipe 10. The blade 3 is movably mounted above the conveyor belt 1, positioned between the two mounting plates 2. The observation chamber 8 is mounted on the outer wall of one of the mounting plates 2. A row of gas pipes 9 is installed on one side of the upper outer wall of the observation chamber 8, and a drain pipe 10 is installed on the other side. Observation plates, made of transparent acrylic sheets, are installed on both sides of the observation chamber 8. Cylinders 6 are fixedly installed on the outer walls of both mounting plates 2, and the two ends of the blade 3 are fixedly connected to the output ends of the cylinders 6.

[0016] A fixing plate 7 is fixedly installed on one side of the outer wall of one of the mounting plates 2. An observation chamber 8 is fixedly installed above the fixing plate 7. The observation chamber 8 has an opening facing the side of the mounting plate 2. A slot is provided on the side of the mounting plate 2 near the opening of the observation chamber 8. A cylinder 5 is installed on one side of one of the mounting plates 2. The cylinder 5 is installed on the mounting plate 2 away from the observation chamber 8. The cylinder 5 is fixedly installed on the outer wall of the mounting plate 2. A push plate 4 is fixedly installed at the output end of the cylinder 5. The push plate 4 is installed facing the observation chamber 8.

[0017] A U-shaped groove is formed through the outer wall of the fixing plate 7. A motor 13 is fixedly installed at the bottom of the fixing plate 7. A screw 14 is fixedly installed at the output end of the motor 13. One end of the screw 14 is connected to the outer wall of the mounting plate 2 through a bearing. A slider 12 is fitted to the outer wall of the screw 14. A connecting plate 11 is fixedly installed above the slider 12. The connecting plate 11 passes through the U-shaped groove and has multiple needles fixedly installed at its top.

[0018] Example: Polystyrene sheets are transported on conveyor belt 1. At this time, the ends of the polystyrene sheets have not been ground or trimmed. When a portion of the sheet passes under the blade 3, cylinder 2 6 drives the blade 3 to fall and cut the end of the sheet. After cutting, cylinder 1 5 is activated, pushing push plate 4. Push plate 4 pushes the cut portion towards the observation chamber 8. Initially, the spikes at the top of the connecting plate 11 are close to the slots on the mounting plate 2. As push plate 4 pushes, the spikes embed into the sheet, fixing the connecting plate 11 and the sheet. Then, motor 13 is activated, and slider 12 is driven by screw 14. The slide plate 12 then moves the connecting plate 11, which in turn moves the plate through the needles, pulling it above the fixed plate 7. Combustible gas is then injected into the gas pipe 9 at the top of the observation chamber 8. The observation chamber 8 has a built-in igniter that ignites the gas, causing a flame to erupt from the gas pipe 9. The flame contacts the plate, and the operator observes the ignition status through a transparent window. If the plate is not visibly ignited, it indicates that the plate's flame retardancy is up to standard. The gas pipe 9 is then shut off, and water is sprayed from the water pipe 10 to cool the plate. The operator removes the experimental plate from the observation chamber 8. If the experimental plate is visibly burning, it indicates that the plate's flame retardancy is not up to standard. The operator will immediately shut off the gas pipe 9, open the water pipe 10 to extinguish the flame, and the batch of plates will be scrapped and recycled.

[0019] It should be noted that the parts not covered in this utility model are the same as or can be implemented using existing technology; the various drives in this utility model can be implemented by corresponding power structures such as cylinders, oil cylinders, electric cylinders, and motors in conjunction with connecting rods, guide rods, etc., and are not limited to the structures described in the specification and the drawings.
