[0023] Embodiment 1
[0024] Refer to Figure 1-2, 5, is the first embodiment of the present utility model, providing a feeding mechanism for an injection molding machine, including: a rectangular outer frame 1 and a feeding cylinder 2. The feeding cylinder 2 penetrates through the upper surface of the rectangular outer frame 1. A rectangular filter plate 3 is slidably connected to the vertical surface inside the rectangular outer frame 1. An arc-shaped baffle 4 is fixedly connected to the vertical surface inside the rectangular outer frame 1. A feeding port is penetrated and opened on the upper surface of the arc-shaped baffle 4. A pair of rotating rods 5 penetrate through between the long vertical surfaces inside the rectangular outer frame 1, and a crushing cylinder 6 is fixedly connected to the rod body of the rotating rod 5. A pair of connecting plates are further provided on the lower surface of the arc-shaped baffle 4, and an arc-shaped protective sleeve 7 is provided on the lower surface of the connecting plate. Lifting grooves 8 are opened on the short vertical surfaces inside the rectangular outer frame 1.
[0025] An arc-shaped guiding frame 9 is penetrated and communicated with the upper surface of the rectangular filter plate 3. The vertical part at the lower end of the arc-shaped guiding frame 9 is slidably connected to a rectangular receiving sleeve 10, and the rectangular receiving sleeve 10 is fixedly connected to the arc-shaped baffle 4.
[0026] A pair of mutually meshing gear columns 11 are fixedly connected to the arc-shaped parts of the rotating rods 5 outside the rectangular outer frame 1. A driving motor 12 is provided directly below the gear columns 11. A transmission wheel 13 is fixedly connected to the output end of the driving motor 12 and the rod body of one of the rotating rods 5. A pair of transmission wheels 13 are both connected to a belt 14. An aggregate funnel 15 is provided at the cross-section of the lower end of the rectangular outer frame 1. The cross-section of the lower end of the aggregate funnel 15 is penetrated and communicated with a placement frame.
[0027] During use, first start the driving motor 12. Because a transmission wheel 13 is fixedly connected to the output end of the driving motor 12 and the rod body of one of the rotating rods 5, and a pair of transmission wheels 13 are both connected to the belt 14, as the driving motor 12 rotates, the rotating rod 5 will also rotate. Because a pair of mutually meshing gear columns 11 are fixedly connected to the arc-shaped parts of the rotating rods 5 outside the rectangular outer frame 1, when one of the rotating rods 5 rotates, the other rotating rod 5 can be driven to rotate through the mutually meshing gear columns 11. Because the rod body of the rotating rod 5 is fixedly connected to the crushing cylinder 6, the crushing cylinder 6 will rotate. At this time, the plastic raw materials can be poured through the feeding cylinder 2. Then start the vibration device outside the rectangular outer frame 1. Under the operation of the vibration device, larger particles will be blocked above the rectangular filter plate 3, and the raw materials of the appropriate size will fall onto the upper surface of the arc-shaped baffle 4, and finally fall into the aggregate funnel 15 through the feeding port opened on the arc-shaped baffle 4. The larger raw materials continuously accumulate. During the accumulation process, they fall into the inside of the arc-shaped guiding frame 9 through vibration, and finally the raw materials are conveyed between the pair of crushing cylinders 6 through the arc-shaped guiding frame 9, thus enabling the crushing process.
[0028] Embodiment 2
[0029] Refer to Figure 1 、3 4. This is the second embodiment of the present utility model. The difference between this embodiment and the first embodiment is that a rectangular lifting plate 16 is provided at the vertical plane of the rectangular filter plate 3 close to the lifting groove 8. A plurality of guide rods 17 with the same spacing are provided at the bottom surface inside the lifting groove 8. A memory spring 18 is provided at the bottom surface of the lifting groove 8, and the top end of the memory spring 18 is connected to the bottom surface of the rectangular lifting plate 16.
[0030] A rectangular limiting plate 19 is provided at the bottom surface inside the lifting groove 8, and a rotating cylinder 20 penetrates through the vertical planes of a pair of rectangular limiting plates 19. Round rods 21 are provided at the cross-sections of the rotating cylinder 20 and the rectangular lifting plate 16, and a ring sleeve 22 is connected between the pair of round rods 21. A rectangular connecting plate is provided on the upper surface of the arc-shaped baffle 4, and a removing structure 23 is provided on the upper surface of the rectangular connecting plate. A driving motor is also provided on the vertical plane outside the rectangular outer frame 1, and the output end of the driving motor is connected to the circular surface of the rotating cylinder 20. The rotating cylinder 20 and the rectangular limiting plate 19 are in a rotating relationship.
[0031] During use, first follow the operation steps in Embodiment 1. When it is found that the rectangular filter plate 3 is blocked, start the driving motor provided on the vertical plane of the rectangular outer frame 1. Since the output end of the driving motor is connected to the circular surface of the rotating cylinder 20, and the rotating cylinder 20 and the rectangular limiting plate 19 are in a rotating relationship, as the rotating cylinder 20 rotates, because round rods 21 are provided at the cross-sections of the rotating cylinder 20 and the rectangular lifting plate 16, and a ring sleeve 22 is connected between the pair of round rods 21, as the rotating cylinder 20 rotates continuously, the ring sleeve 22 will drive the rectangular filter plate 3 to descend. Since a rectangular connecting plate is provided on the upper surface of the arc-shaped baffle 4, and a removing structure 23 is provided on the upper surface of the rectangular connecting plate, and a cylindrical rod with the same hole size as that of the rectangular filter plate 3 is provided on the removing structure 23, as the rectangular filter plate 3 descends continuously, several cylindrical rods will push out the particles stuck on the rectangular filter plate 3, so that the rectangular filter plate 3 can achieve the filtering ability.
[0032] The remaining structures are the same as those in Embodiment 1.
