[0002] Packaging equipment is usually used to pack powdered or granular materials, dividing them into multiple packages of equal quality to facilitate their subsequent centralized storage or transportation. During the packaging process, a feeding device is required to transport the materials to the packaging area.

At this time, the material slides down the inclined surface of the hopper 2 to the inside of the rectangular frame 4, thereby filling the inside of the rectangular frame 4. At this time, the cylinder 6 is controlled to extend its inner piston rod 7, thereby pushing the rectangular frame 4 to slide on the inside of the chute 3 toward one end of the trough plate 9. At this time, the scraper 8 scrapes out the excess material on the surface of the rectangular frame 4. After the rectangular frame 4 moves to the top side of the trough plate 9, the material falls into the inside of the trough plate 9 and is then transported to the packaging equipment body 17 for packaging. After that, the cylinder 6 is controlled to retract the rectangular frame 4 to the inside of the hopper 2. The cycle operation realizes the function of quantitative material transportation by cyclically transporting a fixed volume of material, and the transportation efficiency is higher, without the need for frequent weighing.

[0022] See also Figure 3 As shown, the loosening mechanism includes a top plate 10, which is located in the middle position of the top side of the hopper 2, and a driving motor 11 is fixedly installed on the bottom side of the top plate 10, and a rubber block 12 is fixed to the output end of the driving motor 11, and one end of the rubber block 12 contacts the surface of the top plate 10 during rotation, and a flat plate 13 is fixed to the inner end of the support plate 1; during operation, when encountering material blockage, which causes the device to be unable to quantitatively transport materials, the driving motor 11 is controlled through the structure of the loosening mechanism to drive the rubber block 12 at the output end to rotate rapidly. During the rotation of the rubber block 12, it frequently hits the bottom surface of the top plate 10, thereby driving the hopper 2 to vibrate through the top plate 10, and dredging the material inside the hopper 2, thereby playing the role of loosening the material, and ensuring that the device can continuously and quantitatively feed the material.

[0023] See also Figure 4As shown, the cleaning mechanism includes a flat plate 13, and air holes 14 are evenly opened on the surface of the flat plate 13.

One side of the slot plate 9 is placed on the packaging device body 17. During operation, when encountering the problem that materials are adhered to the inner wall of the frame and affect the conveying of materials, the structure of the cleaning mechanism is used to control the air pump 15 to convey air to the closed area on the top side of the flat plate 13 through the conduit 16. At this time, the air is ejected from the air holes 14 on the bottom side of the flat plate 13. When the rectangular frame 4 moves to the top side of the slot plate 9, the air is ejected through the air holes 14 to blow away the logistics adhered to the inner surface of the rectangular frame 4, thereby ensuring that the device can convey materials normally.

[0024] See also Figure 5 As shown, the inner side of the rectangular frame 4 is evenly provided with limit grooves 18, and the inner side of the limit grooves 18 is buckled with a clamping block 19; when working, when encountering the problem of being unable to adjust the single feeding quality, through the structure of the clamping block 19, a suitable number of clamping blocks 19 are selected and buckled on the inner side of the limit groove 18, thereby changing the inner capacity of the rectangular frame 4, realizing the function of adjusting the single feeding quality, and making the device more flexible and convenient to use.

[0025] Working principle: Packing equipment is usually used to pack powdery materials or granular materials, and divide them into multiple packages of equal quality, so as to facilitate their subsequent centralized storage or transportation. During the packing process, a feeding device is required to transport the materials to the packing area. During the packing process, the existing feeding device needs to first transport the materials to the weighing structure, and then pack them after weighing. The operation is relatively cumbersome, and the processing efficiency of the packing equipment is low. In order to solve this problem, a feeding mechanism and a cleaning mechanism are set up to add the material to be packed into the hopper 2. At this time, the material slides from the inclined surface of the hopper 2 to the inside of the rectangular frame 4, thereby filling the inside of the rectangular frame 4. At this time, the cylinder 6 is controlled to extend its inner piston rod 7, thereby pushing the rectangular frame 4 to slide on the inside of the chute 3 toward one end of the trough plate 9. At this time, the scraper 8 scrapes out the excess material on the surface of the rectangular frame 4. At this time, the partition 5 can prevent the material inside the hopper 2 from falling into the inside of the chute 3. After the rectangular frame 4 moves to the top side of the trough plate 9, the material The material falls into the inner side of the groove plate 9 and is then transported to the packaging equipment body 17 for packaging. At the same time, the air pump 15 is controlled to transport air to the closed area on the top side of the flat plate 13 through the conduit 16. At this time, the air is ejected from the air holes 14 on the bottom side of the flat plate 13. When the rectangular frame 4 moves to the top side of the groove plate 9, the air is ejected through the air holes 14 to blow away the logistics adhering to the inner surface of the rectangular frame 4. Then the cylinder 6 is controlled to retract the rectangular frame 4 to the inside of the hopper 2, and the drive motor 11 is controlled to drive the output end rubber block 12 to rotate rapidly. During the rotation of the rubber block 12, it frequently hits the bottom surface of the top plate 10, thereby driving the hopper 2 to vibrate through the top plate 10, dredging the material inside the hopper 2, so that the material can fall into the inside of the rectangular frame 4, preventing blockage during the material transportation process, and cyclically operating the device to achieve the function of quantitative material transportation by cyclically transporting a fixed volume of material, thereby solving the problem of low working efficiency of the existing feeding device.
