Description

technical field [0001] The invention relates to a manufacturing equipment for extruded polystyrene foam boards, in particular to a cross-cutting device for producing extruded polystyrene foam boards. Background technique [0002] Extruded polystyrene foam board, also known as XPS extruded board, is a material that is continuously extruded and foamed by a special process. structure, so it has the characteristics of high compression resistance, light weight, non-water absorption, airtight wear resistance, and non-degradation. Compared with EPS polystyrene foam board, its strength, heat preservation, and water vapor penetration resistance have been greatly improved. It is especially suitable for heat insulation, heat preservation, and moisture-proof treatment of buildings. It is one of the high-quality and cheap construction materials in today's construction industry. [0003] XPS extruded board has the characteristics of high thermal resistance, low linearity, and low expansi...

AI Technical Summary

Problems solved by technology

Since the cross-cutting is also cut with a saw blade, dust is generated, which can easily block the photoelectric switch and affect the stable operation.

If the length of the insulation board produced changes, it is very inconvenient to adjust the photoelectric switch to change the length, and it will cause continuous production or a lot of unqualified products in the middle, and the board length accuracy and stability are also relatively poor. It adopts the working principle Yes, when the signal from the photoelectric switch arrives, the cylinder of the device is pressed down, and the saw blade moves quickly from one side to the other on the moving trolley. Although the time is extremely short, since the trolley cannot move at the same speed as the board, it will inevitably result in continuous production of boards. Deformation extrusion, because the cooling frame is longer, it can withstand short-term deformation extrusion, but it still has a certain impact on the quality of the board. Later, many manufacturers also improved. They use photoelectric switches or encoders to measure the length. The saw blade trolley is equipped with a trolley that moves along the direction of the plate. Through frequency conversion speed regulation, a similar linear speed is adjusted to catch up in advance. When the caught up linear speed is consistent with the linear speed measured by the encoder, the cylinder is pressed down. The saw trolley moves quickly from side to side

Although the problem of producing plates after extrusion is approximately solved, the length cannot be precisely controlled, because its accuracy depends on the arrival of each signal.

In this process, the distance used for acceleration must be consistent each time to ensure accuracy. It requires no changes in electrical and mechanical aspects, and even the grid voltage must not change in any way, so as to ensure that each time the car is used to accelerate and chase. The distance is the same, this is theoretical, it is impossible to have such electrical and mechanical consistency in actual production, so the length accuracy varies within 1cm, and the accuracy is not high

[0006] Moreover, for the plate produced due to the uncontrollable length, only the electric heating wire can be used for secondary cutting, which increases manpower and cost
