[0025] The primary storage bin 5 of the device is the main raw material temporary storage unit, which bears the heavy responsibility of storing molten raw materials for subsequent processing links in the production process, and its storage capacity and feeding rhythm have a direct impact on the continuity of production. Compared with the existing technology, the extrusion type melting machine is usually connected with only one storage bin, and the device also increases the secondary storage bin 8, which is used to store the excess molten raw materials when the processing capacity of the primary storage bin 5 is saturated, and plays an auxiliary storage and buffering role to prevent raw material backlog or supply interruption. The use of the device has the following advantages: it can effectively shorten the production cycle, which can be shortened by 20% or more according to different products; it avoids the wear caused by frequent start and stop of the extrusion type melting machine, thereby effectively prolonging the service life of these key components; through the design of the main bin body 1 and the control of the switching valve 10, the raw material flow can be better planned and fixed, the production process can be optimized, and the production efficiency and stability can be improved.
[0026] As shown in Figure 4 , the switching valve 10 includes a pushing part 1001 and a working part 1002 fixed on the end face of the pushing part 1001. The structure of the pushing part 1001 of the switching valve 10 is a cylinder, and the pushing part 1001 of the switching valve 10 is fixed outside the main bin body 1. The structure of the working part 1002 of the switching valve 10 is a cylinder that fits the movable groove 102 inside the main bin body 1. The end of the working part 1002 of the switching valve 10 away from the pushing part 1001 is provided with an arc-shaped notch. The working part 1002 of the switching valve 10 is slidingly arranged in the movable groove 102 of the main bin body 1 and can extend out of the main bin body 1. When the secondary storage bin 8 is storing materials, as shown in Figure 2 , the switching valve 10 is in a closed state. The setting of the arc-shaped notch increases the space of the movable groove 102 not occupied by the switching valve 10, so that the amount of raw materials that the movable groove 102 can accommodate increases, effectively alleviating the wear caused by the frequent start and stop of the extrusion type melting machine, thereby prolonging the service life of these key components. When the primary storage bin 5 is storing materials, as shown in Figure 1 , the switching valve 10 is in an open state. At this time, the discharge port 3 is blocked by the side wall of the switching valve 10, and the first material passage 4 can communicate with the movable groove 102 due to the setting of the arc-shaped notch, thereby providing a space for the raw materials to flow into the primary storage bin 5, avoiding the need to set a curved through hole 11 to connect the first material passage 4 and the discharge port 3 which are staggered in position on the main bin body 1, and reducing the operation difficulty when the device bores the through hole 11 on the switching valve 10.
[0027] As shown in Figure 5The first storage bin 5 is a hollow cylindrical structure, one end of the first storage bin 5 is fixed to the side of the main bin body 1, the internal space of the first storage bin 5 includes a first passing part 501 away from the main bin body 1 and a first buffer part 502 close to the main bin body 1, and the diameter of the first buffer part 502 gradually decreases in the direction close to the main bin body 1. This setting plays a buffering role for the raw material entering and leaving the first storage bin 5.
[0028] As shown in Figure 5 The first bin push head 6 is composed of a first movable block 601 in a cylindrical structure and a first push rod 602 fixed to the end face of the first movable block 601, and the outer periphery of the first movable block 601 is provided with a first protrusion 12. The first protrusion 12 can increase the contact area between the first movable block 601 and the inner wall of the first storage bin 5, increase the friction, and further buffer the raw material entering and leaving the first storage bin 5.
[0029] As shown in Figure 6 The second storage bin 8 is a hollow cylindrical structure, one end of the second storage bin 8 is fixed to the top surface of the main bin body 1, the internal space of the second storage bin 8 includes a second passing part 801 away from the main bin body 1 and a second buffer part 802 close to the main bin body 1, and the diameter of the second buffer part 802 gradually decreases in the direction close to the main bin body 1. This setting plays a buffering role for the raw material entering and leaving the second storage bin 8.
[0030] As shown in Figure 6 The second bin push head 9 is composed of a second movable block 901 in a cylindrical structure and a second push rod 902 fixed to the end face of the second movable block 901, and the outer periphery of the second movable block 901 is provided with a second protrusion 14. The second protrusion 14 can increase the contact area between the second movable block 901 and the inner wall of the second storage bin 8, increase the friction, and further buffer the raw material entering and leaving the second storage bin 8.
[0031] Working principle:
[0032] Before working, the device needs to be connected to the end of the extrusion type melting material machine, that is, the output end of the extrusion type melting material machine is connected to the feeding port 2 of the device.
[0033] When the device works, it is divided into two states: the first storage bin 5 stores material and the second storage bin 8 stores material.
[0034] The first storage bin 5 stores material (as shown in Figure 1 The switching valve 10 is opened, one side of the switching valve 10 blocks the discharge port 3, the feeding port 2 is communicated with the first passing port 4, and the second bin push head 9 is pressed down to close the second storage bin 8; the raw material enters from the feeding port 2, enters the first storage bin 5 through the movable groove 102, and the first storage bin 5 temporarily stores the raw material;
[0035] Secondary storage bin 8 storage (e.g.) Figure 2 (As shown): After the raw materials in the primary storage bin 5 reach the production demand, the switching valve 10 is closed. The through hole 11 on the switching valve 10 is connected to the first material outlet 4 and the discharge outlet 3 respectively. At this time, the primary bin pusher 6 is activated to push the material in the primary storage bin 5 out through the first material outlet 4, through hole 11 and discharge outlet 3. At the same time, the secondary bin pusher 9 is pulled, and the raw materials entering from the inlet 2 enter the secondary storage bin 8 through the movable groove 102 and the second material outlet 7. The secondary storage bin 8 provides auxiliary storage for the raw materials.
[0036] After the primary storage silo 5 is emptied, the switching valve 10 is opened again to restore the storage process of the primary storage silo 5. The two states cycle repeatedly to ensure continuous production.
