[0007] The extrusion device includes multiple mounting frames and multiple elastic members, which are staggered. An extrusion airbag is fixedly mounted on the mounting frame, and the extrusion airbag has a rectangular structure. An annular airbag is rotatably connected to the elastic member.

[0013] Compared with the related art, the positioning device for cutting polyurethane foam material provided by the utility model has the following beneficial effects:

[0022] In the specific implementation process, Figures 1-4 As shown, it includes a workbench 1, on which a driving device is installed, and a transverse plate 2 is installed on both movable ends of the driving device, and two movable longitudinal plates 3 are installed at both ends of the transverse plate 2, and an extrusion device is installed on both the transverse plate 2 and the longitudinal plate 3, and the extrusion device includes a plurality of mounting frames 6 and a plurality of elastic members, and the plurality of mounting frames 6 and the plurality of elastic members are staggered. Among them, an extrusion airbag 5 is fixedly installed on the mounting frame 6, and the extrusion airbag 5 is a rectangular parallelepiped structure. An annular airbag 4 is rotatably connected to the elastic member. Through the two movable transverse plates 2 and the movable longitudinal plate 3 on the transverse plate 2, the size of the fixed polyurethane foam material is no longer single, thereby improving the flexibility of use. Through the rotation of the annular airbag 4, when the plate moves, it is not easy to directly contact the transverse plate 2 and the longitudinal plate 3, thereby reducing friction;
[0023] The elastic member includes a telescopic member, a spring 7 and a placement frame 8. The spring 7 is sleeved on the telescopic member. One end of the telescopic member is fixedly connected to the placement frame 8. The placement frame 8 is rotatably connected with an insertion rod 9. The annular airbag 4 is fixedly sleeved on the insertion rod 9. The telescopic member includes a sleeve 10 and a movable rod 11. One end of the movable rod 11 is movably arranged in the sleeve 10, and the other end of the movable rod 11 is fixedly connected to the placement frame 8. The extrusion device on the transverse plate 2, the mounting frame 6, the sleeve 10 and the spring 7 are all fixedly connected to the side wall of the transverse plate 2. The extrusion device on the longitudinal plate 3, the mounting frame 6, the sleeve 10 and the spring 7 are all fixedly connected to the side wall of the longitudinal plate 3;
[0024] The driving device includes a bidirectional screw 13 and two transmission plates 12. The bidirectional screw 13 is rotatably connected to the workbench 1. The two transmission plates 12 are respectively threadedly connected to the two ends of the bidirectional screw 13, and the two transmission plates 12 are movably inserted into the through holes opened in the workbench 1. The two transmission plates 12 are respectively fixedly connected to the two transverse plates 2. A motor 14 is installed on the workbench 1. The output end of the motor 14 is fixedly connected to the end of the bidirectional screw 13. The motor 14 drives the bidirectional screw 13 to rotate, so that the two transverse plates 2 approach each other.
[0025] Electric cylinders 15 are fixedly installed at both ends of the transverse plate 2, and the telescopic ends of the electric cylinders 15 are fixedly connected to movable plates 16. The movable plates 16 are movably inserted into the through holes opened in the transverse plate 2. The movable plates 16 are fixedly connected to the longitudinal plates 3. The longitudinal plates 3 are moved by the electric cylinders 15 to adjust the distance between the two longitudinal plates 3.
[0026] The working principle provided by the present utility model is as follows: when the device is used, the polyurethane foam material is placed on the workbench 1, and the bidirectional screw 13 is driven to rotate by the motor 14, so that the two transverse plates 2 are close to each other. When the polyurethane foam material is placed offset, the annular airbag 4 on one side first contacts the plate and pushes the plate toward the center of the workbench 1. If the plate contacts the annular airbag 4 of the longitudinal plate 3, the annular airbag 4 rotates, thereby reducing the friction force on the plate during movement. Then, the longitudinal plate 3 is driven to move by the electric cylinder 15, and the longitudinal airbag of the transverse plate 2 rotates. As the transverse plate 2 and the longitudinal plate 3 move, the spring 7 is compressed, so that the extrusion airbag 5 contacts the plate. The annular airbag 4 and the extrusion airbag 5 jointly limit the plate to enhance the fixing effect.
