Description

Technical Field

[0001] The utility model relates to the technical field of foam board processing equipment, in particular to a foam board strip cutting device. Background Art

[0002] Foam board, also known as polystyrene board, is a white object made of expandable polystyrene beads containing volatile liquid foaming agent, which is pre-expanded by heating and then heated and formed in a mold. It has the structural characteristics of fine closed cells and is mainly used for building walls, roof insulation, composite board insulation, cold storage, air conditioning, vehicle, ship insulation, floor heating, decoration and carving, etc. It has a wide range of uses.

[0003] At present, foam boards need to be processed into strips for easy assembly and positioning. The existing foam board cutting equipment uses a cutter for cutting, which easily causes deformation of the foam board during the cutting process, resulting in poor flatness of the cut surface of the foam board after cutting and low production efficiency. In addition, there are also equipment that uses electric heating wire to cut foam boards. Compared with the cutting efficiency of the cutter, however, cutting the foam board with the electric heating wire is prone to produce toxic gases, which will cause harm to the operator's body and seriously pollute the environment. In the process of cutting the foam board, the foam board needs to be pressed manually, otherwise the foam board is prone to deviation and side shifting, the cutting accuracy is low, and the manual labor intensity is high.

The frame 1 is suspended by the four legs 10. One end of the frame 1 is set as a loading end for adding foam boards to the frame 1 for cutting, and the other end is set as a unloading end for unloading the cut foam boards. A horizontal active roller 11 is horizontally arranged at the loading end of the frame 1. The two ends of the active roller 11 are rotatably supported by two first shaft seats arranged on the frame 1. One end of the active roller 11 is set for driving The motor 111 drives the rotation of the motor 111, and the unloading end of the frame 1 is provided with a driven roller 12 parallel to the active roller 11. The two ends of the driven roller 12 are supported by two second shaft seats provided on the frame 1. The active roller 11 and the driven roller 12 are connected by multiple conveyor belts 13. The two ends of each conveyor belt 13 are respectively connected to the two pulleys 14 corresponding to the active roller 11 and the driven roller 12. A vertical heating wire 2 is provided between the adjacent two conveyor belts 13. The heating wire 2 is an existing commercially available product. It heats the foam board by connecting the power supply. For cutting, the diameter of the heating wire 2 is 0.25mm, and the cutting seam of the heating wire 2 is only 1mm, which can greatly reduce the plate loss rate. A first crossbeam 15 is set above the frame 1 and a second crossbeam 16 is set below. The two ends of the first crossbeam 15 are supported and fixed by two first vertical beams 17 set on the top of the frame 1, and the two ends of the second crossbeam 16 are supported and fixed by two second vertical beams 18 set at the bottom of the frame 1. The upper end of each heating wire 2 is connected to the first crossbeam 15 and the lower end is connected to the second crossbeam 16. The upper and lower ends of each heating wire 2 correspond to the first crossbeam 1 5. Two threaded holes are provided on the second crossbeam 16, and each internal threaded hole is threadedly connected to an adjusting screw 153. The upper and lower ends of the heating wire 2 are respectively connected to the first crossbeam 15 and the adjusting screw 153 on the second crossbeam 16 are fixedly connected. The adjusting screw 153 is made of insulating material. The two adjusting screws are used to facilitate keeping the heating wire 2 in a vertical tensioned state. The active roller 11 is driven to rotate by the motor 111, driving the conveyor belt 13 to transport the foam board through the nine heating wires 2, so that the foam board is quickly cut into strips with high cutting efficiency and high cutting accuracy.

The negative pressure exhaust pipe 151 is a hollow tube with both ends closed. A plurality of air intakes 152 are set at the bottom of the negative pressure exhaust pipe 151. One end of the negative pressure exhaust pipe 151 is connected to the negative pressure pipeline to suck the polluted gas generated by the hot-melt cutting of the foam board (the main components are toxic gases such as carbon monoxide and hydrogen cyanide) into the negative pressure exhaust pipe 151 from the air intake 152, and then collected through the negative pressure pipeline to the exhaust treatment equipment for treatment to prevent the harmful gas from polluting the environment.

[0039] It can be seen from the above technical solution that when in use, first, the foam board is placed horizontally on the feeding end of the conveyor belt 13, and the guide rod 72 is used to guide and move in the guide hole 711 to push the positioning plate 73 to fit tightly with one side of the foam board on the conveyor belt 13 for positioning, and then the front end of the conveyor belt 13 is used to make the cutting surface of the foam board consistent with the shape of the foam board, and then the positioned foam board is pressed by lifting the pressure roller 3. At the same time, the controller controls the heating wire 2 to be energized and heated, and then the motor 111 drives the active roller 11 to rotate, driving the conveyor belt 13 to transport the foam board longitudinally through the nine heating wires 2 and cut into strips. During the cutting process, after the foam board passes through the heating wire 2, the other pressure roller 3 is lifted to press the foam board to prevent the foam board from dispersing during the cutting process.
