[0029] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.
[0030] As shown in Figure 1, Figure 2 and Figure 7 As shown, this embodiment provides an automatic feeding device for plastic molding with raw material crushing, including a storage tank 1. The upper end of the storage tank 1 is provided with a feeding hopper 2. Movable cover plates 3 are movably installed on both sides of the upper end of the feeding hopper 2. The lower end of the movable cover plate 3 is provided with a reset structure. The reset structure includes a groove. The groove is opened on both sides of the upper end inside the feeding hopper 2. Multiple fixing rods 23 are evenly fixedly installed inside the groove. A sliding seat 24 is movably sleeved on the surface of the fixing rod 23. A support spring 26 connected to the sliding seat 24 is sleeved on the surface of the fixing rod 23. A movable support rod 25 is rotatably installed on the upper end of the sliding seat 24. One end of the movable support rod 25 is movably connected to the lower end of the movable cover plate 3.
[0031] In this embodiment, the user squeezes the material through the movable cover plate 3 and feeds it into the hopper 2. The movable cover plate 3 rotates downward under force. The movable cover plate 3 drives the sliding seat 24 to move along the fixed rod 23 via the movable support rod 25. The sliding seat 24 compresses the support spring 26, causing the movable cover plate 3 to open. After the material is fed in, the sliding seat 24 returns to its original position under the action of the support spring 26. The sliding seat 24 drives the movable cover plate 3 to rotate via the movable support rod 25, so that the movable cover plate 3 can close the hopper 2, preventing the material from splashing when the crushing teeth 22 crush the plastic material, thus avoiding the impact on the workers and the surrounding environment.
[0032] As shown in Figure 1, Figure 2 and Figure 7As shown, this embodiment provides an automatic feeding device for plastic molding with raw material crushing. Two rotating shafts 6 are rotatably installed inside the feeding hopper 2. Crushing teeth 22 are provided on the surface of the rotating shafts 6. One end of the two rotating shafts 6 extends to the outside of the feeding hopper 2 and is equipped with meshing gears 7. The two meshing gears 7 mesh with each other. A driver 4 is installed on one side of the surface of the feeding hopper 2. The output end of the driver 4 is connected to one of the rotating shafts 6. A grate 9 is detachably installed at the lower end inside the feeding hopper 2.
[0033] In this embodiment, the driver 4 drives one rotating shaft 6 to rotate. The two rotating shafts 6 rotate simultaneously through meshing gears 7. The two rotating shafts 6 rotate towards the middle, which facilitates the crushing of plastic material by crushing teeth 22. The crushed plastic material falls onto the grate plate 9, which facilitates the filtering of the material. The crushed and filtered plastic material can fall into the storage tank 1 for feeding.
[0034] like Figure 2 and Figure 4 As shown, this embodiment provides an automatic feeding device for plastic molding with raw material crushing. A slot is opened on one side of the feeding hopper 2. An installation seat 5 is fixedly installed on the surface of the feeding hopper 2 on one side of the slot. The grate plate 9 is inserted into the inside of the feeding hopper 2 through the slot. An installation groove 11 is opened in the middle of both sides of the installation seat 5. A slot 12 connected to the installation groove 11 is opened on both sides of the installation seat 5. One end of the grate plate 9 extends into the inside of the installation seat 5 and is installed with an installation plate 10. A movable groove is opened in the middle of both ends of the installation plate 10. A movable block 15 is movably installed inside the movable groove. An installation rod 13 is fixedly installed on one side of the movable block 15. One end of the installation rod 13 extends through the installation groove 11 into the inside of the slot 12 and is installed with a locking block 16. The locking block 16 is engaged with the slot 12. A locking spring 14 connected to the movable block 15 is sleeved on the surface of the installation rod 13.
[0035] In this embodiment, the user pulls the locking block 16, which moves the mounting rod 13. The mounting rod 13 moves the movable block 15 inside the movable slot, compressing the locking spring 14. When the locking block 16 moves out of the slot 12, the mounting rod 13 can be pulled out from inside the mounting slot 11, allowing the mounting plate 10 to be pulled out from inside the mounting base 5. This allows the grate plate 9 to be pulled out from inside the feed hopper 2 through the slot, facilitating the installation and removal of the grate plate 9.
[0036] As shown in Figure 5 and Figure 6As shown in the figure, this embodiment provides an automatic feeding device for plastic molding with raw material crushing. The lower end of the grate 9 is provided with an auxiliary feeding structure, which includes a fixing plate 18.
[0037] Fixed plates 18 are fixedly installed on both sides inside the feed hopper 2. Fixed plates 18 are located on both sides below the grate plate 9. Striking rods 19 are movably inserted on both sides of fixed plates 18. Connecting seats 20 are fixedly installed at the lower end of striking rods 19. Return springs 21 connected to connecting seats 20 and fixed plates 18 are sleeved on the surface of striking rods 19. Rotating rods 8 are rotatably installed on both sides of the lower end inside the feed hopper 2. The two rotating rods 8 are connected to each other through a transmission sprocket and a transmission chain. One of the rotating rods 8 is connected to one of the rotating shafts 6 through a transmission sprocket and a transmission chain. Cams 17 that fit with connecting seats 20 are fixedly sleeved at both ends of rotating rods 8.
[0038] In this embodiment, when the rotating shaft 6 rotates, it drives a rotating rod 8 to rotate via a transmission sprocket and a transmission chain. The two rotating rods 8 rotate synchronously under the action of the transmission sprocket and the transmission chain. The rotating rod 8 drives the cam 17 to rotate. When the longer end of the cam 17 contacts the lower end of the connecting seat 20, the connecting seat 20 moves upward. The connecting seat 20 drives the striking rod 19 to move upward, striking the lower end of the grate 9. When the longer end of the cam 17 disengages from the connecting seat 20, the connecting seat 20 and the striking rod 19 move downward under the action of the return spring 21 and gravity, so that the striking rod 19 can move up and down repeatedly, which facilitates repeated striking of the grate 9, avoids blockage of the grate 9, and speeds up the material feeding speed.
