Embodiment 1

[0030] A high-efficiency and safe melting film equipment for flexible polyurethane foam coils, which consists of: a circular pressure-resistant container 1, the circular pressure-resistant container is connected to a circular quick-opening upper door 3 through a circular chuck 2, and the The circular quick-opening upper door is connected to the lifting and translation device 4; wherein, the bottom of the circular pressure-resistant container is connected to a group of gas injection ports 5, and the circular quick-opening upper door is connected to the air suction port 6.

[0031] The circular pressure-resistant container is used to hold the foam roll 7, and is used as a place for pumping, injecting, and igniting and blasting.

Embodiment 2

[0033] According to the high-efficiency and safe melting film equipment for flexible polyurethane foam coils described in Example 1, the circular pressure-resistant container also has an isolation device 8, and the cylinder wall of the circular pressure-resistant container also has a Group monitoring device9.

[0034] The monitoring device also has a pressure sensor and a data processing system.

Embodiment 3

[0036] A processing method of high-efficiency and safe melting film equipment for flexible polyurethane foam coils. The first step is to start the lifting and translation device to open the circular quick-opening door, and install the foam coil with the movable igniter 10 in the center together with the isolation device. into a circular pressure vessel;

[0037] In the second step, after closing the circular quick-opening door, lock it with the circular pressure-resistant container with a circular chuck, and at this time, use the pumping system to vacuumize the container through the pumping port;

[0038] In the third step, after vacuuming, use the gas injection system to inject hydrogen and oxygen through the gas injection port;

Abstract

High-efficiency and safe melting film equipment for flexible polyurethane foam coils and its processing method. One of the existing foam blasting melt film technologies is to cut the rectangular foam blocks into coils after melting the film, which wastes man-hours and materials, and the surface pore size and physical properties of the unfolded coils are not uniform; The membrane reticulation coil is put into the melting film equipment of the rectangular container to melt the membrane reticulation, resulting in a waste of melting film space, deformation or damage of the coil; the existing equipment is simple and unfavorable to safe operation, process design and uniform distribution of blasting force. The method of the present invention includes: a circular pressure-resistant container (1), the circular pressure-resistant container is connected to a circular quick-opening upper door (3) through a circular chuck (2), and the circular quick-opening upper door is connected to a lift A translation device (4); wherein, the bottom of the circular pressure-resistant container is connected to a group of gas injection ports (5), and the circular quick-opening upper door is connected to a gas extraction port (6). The invention is used for reticulated foam processing.

Description

[0001] Technical field: [0002] The invention relates to a high-efficiency and safe melting film equipment for flexible polyurethane foam coils and a processing method thereof. [0003] Background technique: [0004] Existing production methods of reticulated foam coils: one is to use a rotary cutting device to cut off the four corners of the rectangular foam block after the melt film is reticulated to form a cylinder, and then perform spiral cutting. Gradually cut, the cylindrical foam block is cut into a super long thin sheet with use value, and then packed in rolls for storage and transportation. [0005] Another method is to cut the extra-long unmelted film reticulated rectangular foam block from top to bottom into super-long thin sheets of required thickness layer by layer, and then roll them into rolls, and then roll the rolls The material is put into the melting film equipment of the rectangular container for melting film reticulation treatment to obtain reticulated fo...
