The bent end of the upper end of the feed pipe 2 is coaxially arranged with the bent end of the lower end of the feed pipe 4, and is located in the same plane as the axis of each cylinder 6. The axis of the cylinder 6 intersects the axis of the rotating ring 5 at right angles. The plurality of cylinders 6 are distributed in a circular array around the axis of the rotating ring 5. When the feed pipe 4 is connected to the cylinder 6, the polyurethane raw material can be filled into the cylinder 6.

[0026] A quantitative rod 7 is slidably inserted inside the cylinder 6, and a push plate 13 is provided on the side of the quantitative rod 7 close to the axis of the rotating ring 5. The push plate 13 is slidably inserted inside the cylinder 6, and the push plate 13 is elastically connected to the adjacent quantitative rod 7 through a push spring 10. The inner ring surface of the cylinder 6 is provided with a plurality of grooves, and the outer ring surface of the push plate 13 is provided with a convex structure with the grooves of the cylinder 6, so that the push plate 13 will not move out of the cylinder 6, and the side of the quantitative rod 7 close to the push plate 13 is a concave structure, and the push spring 10 is located at the quantitative rod 7. Inside the concave structure of the measuring rod 7, when the polyurethane raw material is filled into the cylinder 6, the raw material pushes the push disk 13 to compress the push spring 10 and contact the quantitative rod 7. The quantitative rod 7 and the position limit the maximum capacity of the filling. The upper end of the rotating ring 5 is rotatably sleeved with a dislocation cylinder 11. The upper surface of the inner ring of the dislocation cylinder 11 is threaded with a threaded pressure rod 9. When the threaded pressure rod 9 is rotated and meshed with the dislocation cylinder 11 and pressed downward against the rotating ring 5, the dislocation cylinder 11 and the rotating ring 5 are fixed together. The quantitative rod 7 is located on the outer side of the cylinder 6. The upper surface of the end is fixedly connected with an inner rod 17, and the upper end of the inner rod 17 is slidably sleeved with an inclined frame 12. The distances between the two ends of the inclined frame 12 and the axis of the rotating ring 5 are different. The inner rod 17 is vertically arranged with the connected quantitative rod 7. When the position of the inner rod 17 in the inclined frame 12 is different, the position of the quantitative rod 7 is driven to change differently. The inclined frame 12 is fixedly connected with the outer ring surface of the offset cylinder 11. A gear ring B14 is arranged above the rotating ring 5. The upper surface of the gear ring B14 is fixedly connected with a pressure telescopic rod 15. The other end of the pressure telescopic rod 15 is fixedly connected with a pressure telescopic rod 15. One end is fixedly connected to the offset cylinder 11, and the upper end of the threaded pressure rod 9 is fixedly sleeved with a gear B16, which meshes with the outer ring surface of the gear ring B14. The pressure telescopic rod 15 is in the shape of an arc, and the arc axis of the pressure telescopic rod 15 is coaxially arranged with the rotating ring 5. The pressure telescopic rod 15 meshes with the gear B16 by pushing the gear ring B14, and has a tendency to press the rotating ring 5 after pushing the threaded pressure rod 9 to mesh with the offset cylinder 11. When the gear ring B14 rotates, it can drive multiple threaded pressure rods 9 to rotate synchronously.

[0027] A power structure 8 is installed on the outer surface of the feed pipe 2, and the output end of the power structure 8 is connected to the rotating ring 5. The power structure 8 includes a motor 81, a gear A82 and a gear ring A83. The gear A82 is meshed with the gear ring A83. The gear A82 is fixedly sleeved on the output end of the motor 81. The motor 81 is installed on the outer surface of the feed pipe 2, and the gear ring A83 is installed on the bottom surface of the rotating ring 5. Each time the motor 81 is started, the angle at which the rotating ring 5 is driven to rotate is the angle between two adjacent cylinders 6.

[0028] During use, when the gear ring B14 is not subjected to external force, the pressure telescopic rod 15 pushes the gear ring B14 to mesh with the gear B16, driving the multiple threaded pressure rods 9 to rotate and press against the rotating ring 5, and the position of the inner rod 17 in the inclined frame 12 is fixed. When the rotating ring 5 rotates, it drives different cylinders 6 to be intermittently connected with the lower end of the feeding pipe 4 and the upper end of the feeding pipe 2. The feeding pipe 4 fills the connected cylinders 6 with polyurethane raw materials, pushing the pushing plate 13 to compress the push spring 10 to contact the quantitative rod 7 to achieve the maximum filling amount, and the cylinder 6 and the feeding pipe 2 are connected. When the two ends are connected, the compressed push spring 10 pushes the polyurethane raw material into the feed pipe 2 by pushing the push plate 13, ensuring that the amount of raw material added each time is the same. When the relative pressure telescopic rod 15 is applied to the gear ring B14 to exert a reverse torque, the multiple threaded pressure rods 9 are driven to disengage from the rotating ring 5 synchronously by engaging with the gear B16, so that the offset cylinder 11 can rotate relative to the rotating ring 5, so that the position of the inner rod 17 in the inclined frame 12 changes, and the distance between the inner end of the quantitative rod 7 and the fixed ring 3 is adjusted, so as to synchronously control the amount of raw materials that can be filled into the multiple cylinders 6.

[0029] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
