One end of the folding shaft 5 is fixedly connected to the sealing plate 6. The sealing plate 6 is provided with a gravity sensor 10. Through the coordinated design of the feed hopper 13, the side plate 2, the movable plate 3, the fixed plate 12, the weighing mechanism and the driving mechanism, not only can the effect of quantitative feeding of the raw materials be achieved, but also the problem of the existing problem of foam particles falling easily when the raw materials are transported to the raw material bearing box through the feed funnel, thereby causing a waste of resources, and the structure is simple and more practical.

[0032] In this embodiment, a weighing plate 11 is provided on the top of the sealing plate 6 , and the weighing plate 11 is connected to the gravity sensor 10 for weighing the raw materials in the quantitative barrel 4 .

[0033] In this embodiment, the driving mechanism includes a fixed plate 7, a cylinder 8 and a push rod 9. The fixed plate 7 is fixedly connected to the workbench 1, and the cylinder 8 is fixedly installed on the fixed plate 7. The output end of the cylinder 8 is connected to the quantitative barrel 4 for driving the weighing mechanism, thereby achieving the effect of quantitative feeding.

[0034] In this embodiment, the output end of the cylinder 8 is fixedly connected to a push rod 9, and one end of the push rod 9 is fixedly connected to the quantitative barrel for driving the quantitative barrel 4 to move.

[0035] In this embodiment, a control module 14 is provided on the workbench 1, and the cylinder 8 and the gravity sensor 10 are both connected to the control module 14 for transmission, and are detachably connected.

[0036] In this embodiment, the two side plates 2 are fixedly connected with the same fixing plate 2 12, and the fixing plate 2 12 is slidably connected with the sealing plate 6. The fixing plate 2 12 acts on the sealing plate 6, and the sealing plate 6 rotates in the opposite direction and returns to its original state, and the sealing plate 6 seals the bottom of the quantitative barrel 4.

[0037] In this embodiment, a sliding groove 15 is provided on each of the two side plates 2, and the movable plate 3 slides in the two sliding grooves 15, so as to facilitate the movement of the movable plate 3 and achieve the effect of supporting the movable plate 3 and the quantitative barrel 4.

[0041] Working principle: when in use, the raw materials are conveyed into the quantitative barrel 4 through the feed hopper 13, and the raw materials in the quantitative barrel 4 are weighed through the weighing plate 11 and the gravity sensor 10. When the raw materials in the quantitative barrel 4 reach the set value, the gravity sensor 10 transmits the signal to the control module 14, and the control module drives and controls the cylinder 8. At the same time, the output end of the cylinder 8 drives the push rod 9 to extend, and the push rod 9 pushes the quantitative barrel 4 to move to the left. At the same time, the quantitative barrel 4 drives the moving plate 3 and the sealing plate 6 to move synchronously. When the quantitative barrel 4 drives the sealing plate 6 to separate from the fixed plate 12, the fixed plate 12 releases the support for the sealing plate 6. At the same time, through the action of gravity and the folding shaft 5, the sealing plate 6 rotates a certain angle and separates from the quantitative barrel 4, so that the raw materials in the quantitative barrel 4 fall into the feed port on the foam pre-expander body 17, thereby achieving the quantitative feeding effect;

[0042] When the movable plate 3 slides to the left, the movable plate 3 seals one end of the feed hopper 13, thereby preventing the raw materials from spilling;

[0043] The control module controls the reverse drive of the cylinder 8, so that the output end of the cylinder 8 contracts, and at the same time the push rod 9 pulls the metering barrel 4 to slide to the right, and makes the metering barrel 4 correspond to the feed hopper 13 again. In this process, the fixed plate 12 acts on the sealing plate 6, and makes the sealing plate 6 rotate in the opposite direction and restore its original state, and makes the sealing plate 6 seal the bottom of the metering barrel 4.

[0044] The technical progress achieved by the utility model compared with the prior art is that through the cooperation of various components, not only can the effect of quantitative feeding of raw materials be achieved, but also the problem of foam particles falling easily when the raw materials are transported into the raw material bearing box through the feed funnel, thereby causing waste of resources is solved, and the structure is simple and the practicality is higher.
