[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1.

The baffle blocks the dust and prevents the dust in the material box from escaping when the material is subsequently dumped. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Example 1

[0022] Please refer to Figure 1-3 As shown, the utility model provides a feeding device for an injection molding machine, comprising a base plate 1 and two connecting blocks 7, two vertical rods 2 are installed on the top surface of the base plate 1, and a lifting plate 3 is slidably installed on the outer sides of the two vertical rods 2, a lifting adjustment component for driving the lifting plate 3 to move is provided on the top surface of the base plate 1, a rotating component is provided on one side of the lifting plate 3, a rotating plate 8 is welded to one side of the two connecting blocks 7, one side of the connecting block 7 is connected to the inner side of the lifting plate 3 through a rotating shaft, and the other side of the connecting block 7 is fixed between the rotating component on one side of the lifting plate 3;

[0023] A slide groove 9 is provided on the surface of the rotating plate 8, and a slider 10 is slidably installed inside the slide groove 9. An elastic member connected to the inner wall of the slide groove 9 is provided on one side of the slider 10. The elastic member is specifically a spring 11. One end of the spring 11 is installed on one side of the slider 10 by a screw, and the other end of the spring 11 is installed on one side of the inner wall of the slide groove 9 by a screw. A material box 12 is fixedly installed on the top surface of the slider 10, and a filter screen 13 is provided inside the material box 12. An impurity blocking component is provided inside the material box 12. A vertical plate 17 is fixedly installed on the top surface of the bottom plate 1, and a number of second interference blocks 18 are welded on one side of the vertical plate 17. A number of first interference blocks 16 are installed on one side of the material box 12. The second interference block 18 is hemispherical, and the first interference block 16 is hemispherical.

[0024] Specifically, after the material is put into the material box 12, the material box 12 is controlled to rise, and the interaction between the first resistance block 16 and the second resistance block 18 causes the material to shake, so that impurities on the surface of the material can pass through the filter screen 13 and fall down.

[0025] Among them: the lifting and adjusting component includes a first motor 4, the first motor 4 is installed on the top surface of the base plate 1, and a threaded rod 5 is fixedly installed at the output end of the first motor 4. The threaded rod 5 passes through the lifting plate 3. Turning on the switch of the first motor 4 drives the threaded rod 5 to rotate, thereby driving the lifting plate 3 to move upward or downward.

[0026] Among them: the rotating assembly includes a second motor 6, the second motor 6 is fixedly installed on one side of the lifting plate 3 by bolts, the output end of the second motor 6 passes through the lifting plate 3, and the output end of the second motor 6 is fixed to a connecting block 7 on one side. Turning on the switch of the second motor 6 can drive the rotating plate 8 to rotate through the connecting block 7.

[0027] Among them: the impurity blocking component includes a third motor 14, the third motor 14 is installed on the outside of the material box 12, the output end of the third motor 14 passes through one side of the material box 12, and a baffle 15 is fixedly installed on the output end of the third motor 14. The length and width of the baffle 15 are appropriately matched with the length and width of the lower part of the inner side of the material box 12. Turning on the switch of the third motor 14 drives the baffle 15 to flip 180 degrees, so that the dust on the surface of the baffle 15 falls below the baffle 15 in the inner cavity of the material box 12, and the baffle 15 blocks the dust.

[0028] Working principle: The utility model is a feeding device for an injection molding machine. When in use, rubber raw materials are fed into the material box 12, and the raw materials will fall on the surface of the filter screen 13. Then, the switch of the first motor 4 is turned on, driving the threaded rod 5 to rotate, thereby causing the lifting plate 3 to move upward, and driving the slider 10 and the material box 12 to move upward through the connecting block 7 and the rotating plate 8, thereby lifting the raw materials. In this process, the first resistance block 16 continuously resists the second resistance block 18, and the second resistance block 18 pushes the first resistance block 16 to move in the direction away from the vertical plate 17, thereby driving the material box 12 to move, which can drive the slider 10 to move to one side and reset under the action of the spring 11. When resetting, the slider 10 drives the material box 12 to move in the direction away from the vertical plate 17, so that the material box 12 completes the reciprocating shaking effect. The shaking of the material can cause the dust attached to its surface to fall through the filter screen 13 and fall on the surface of the baffle 15;

[0029] After the material box 12 is lifted to the specified height, the switch of the third motor 14 is turned on to drive the baffle 15 to flip 180 degrees, so that the dust on the surface of the baffle 15 falls below the baffle 15 in the inner cavity of the material box 12. The baffle 15 blocks the dust to prevent it from escaping. At this time, the second motor 6 is controlled to turn on, driving the connecting block 7 and the rotating plate 8 to rotate, so that the material box 12 rotates to one side, thereby dumping the rubber raw material in the material box 12 into the hopper of the injection molding machine, completing the feeding work.
