It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0022] See also Figures 1 to 3In the practical embodiment, an anti-blocking barrel of an injection molding machine is provided.

The lower end of the drop pipe 3 is connected to a feed barrel 4. One end of the lower side of the feed barrel 4 is connected to a feed port 5 connected to the feed end of the injection molding machine. A synchronous drive mechanism is fixedly connected to one side of the storage tank 1. A stirring mechanism is provided in the storage tank 1. A feeding mechanism is provided in the feed barrel 4. Both ends of the synchronous drive mechanism are electrically connected to the stirring mechanism and the feeding mechanism respectively. A dredging mechanism is provided in the drop pipe 3.

[0023] The synchronous drive mechanism includes a rectangular strip shell 6 fixed on one side of the storage tank 1, and a first motor 7 is fixedly connected to one side of the rectangular strip shell 6. The main shaft end of the first motor 7 passes through the rectangular strip shell 6 and is fixedly connected to a double groove wheel 8. One end of the stirring mechanism passes through the rectangular strip shell 6 and is fixedly connected to a first transmission wheel 9. One end of the feeding mechanism passes through the rectangular strip shell 6 and is fixedly connected to a second transmission wheel 10. The double groove wheels 8 are connected to the first transmission wheel 9 and the second transmission wheel 10 through a transmission belt 11. The first motor 7 is started to work and the double groove wheel 8 is driven to rotate. Since the double groove wheel 8 is driven by the first transmission wheel 9 and the second transmission wheel 10 through the transmission belt 11, the stirring mechanism and the feeding mechanism can be driven to work synchronously. Only one motor is needed to realize stirring and feeding operations, saving energy consumption and equipment investment costs, thereby reducing injection molding production costs.

[0024] like Figure 2 As shown: the stirring mechanism includes a cover shell 12 fixed on the upper side of the storage tank 1, and a rotating rod 13 is inserted into the side wall of the cover shell 12 and rotatably connected. One end of the rotating rod 13 penetrates into the rectangular strip shell 6 and is fixedly connected to the first transmission wheel 9. The end of the rotating rod 13 away from the first transmission wheel 9 is fixedly connected to a driving bevel gear 14. A stirring shaft 15 is inserted into the upper side of the storage tank 1 and rotatably connected.

The stirring shaft 15 extends into the storage tank 1 and is fixedly connected to a stirring rod 17. When the first transmission wheel 9 rotates, the rotating rod 13 is driven to rotate. Since the driving bevel gear 14 is meshed with the driven bevel gear 16, the stirring shaft 15 is driven to rotate, which can drive the stirring rod 17 to rotate, so as to stir the plastic particles in the storage tank 1 to prevent accumulation and facilitate material unloading and transportation.

[0025] like Figure 2 As shown: the lower end of the stirring shaft 15 is fixedly connected with a spiral feeding blade 18, which is convenient for forcing the plastic particles in the storage tank 1 into the feeding pipe 3.

[0026] like Figure 2As shown: the feeding mechanism includes a rotating shaft 19 rotatably connected to the inner wall of the feeding barrel 4, one end of the rotating shaft 19 passes through the rectangular strip shell 6 and is fixedly connected to the second transmission wheel 10, and a auger blade 20 is fixedly connected to the rotating shaft 19. When the second transmission wheel 10 rotates, the auger blade 20 on the rotating shaft 19 is driven to rotate, and the plastic particles falling into the feeding barrel 4 can be forcibly transported, and the feeding is stable.

[0027] like Figure 3 As shown: the dredging mechanism includes a casing 21 connected to one side of the blanking tube 3, a second motor 22 is fixedly connected to one side of the casing 21, a main shaft end of the second motor 22 passes through the casing 21 and is fixedly connected to a cam 23, a slide groove 24 is provided on the inner wall of the casing 21, a slider 25 is slidably connected to the inner bottom wall of the slide groove 24, a compression spring 26 is fixedly connected between the inner top wall of the casing 21 and the slider 25, one end of the slider 25 is fixedly connected to a dredging rod 27 arranged in an L shape, one end of the dredging rod 27 extends into the blanking tube 3, when a flow occurs in the blanking tube 3 When blocked, the second motor 22 is started to drive the cam 23 to rotate. When the cam 23 abuts against the slider 25, the slider 25 is pushed upward. At this time, the compression spring 26 is squeezed and contracted to generate elastic force, and at the same time, the dredging rod 27 is driven to move upward. When the cam 23 continues to rotate and separates from the slider 25, the elastic force of the compression spring 26 is used to push the dredging rod 27 fixed to the slider 25 to move downward and reset, thereby realizing the reciprocating up and down displacement movement of the dredging rod 27, thereby dredging the plastic particles in the drop pipe 3, playing a role in preventing blockage, and the anti-blocking effect is good.

[0028] like Figure 3 As shown: two sealing edge strips 28 are fixedly connected to the inner walls on both sides of the inner wall of the connecting port between the blanking pipe 3 and the casing 21, and the dredging rod 27 is arranged between the two sealing edge strips 28 to prevent plastic particles from entering the casing 21 without affecting the up and down displacement of the dredging rod 27.

It is easy to operate and has an external power supply. The circuit involved is a prior art and can be fully implemented by those skilled in the art without further elaboration.

[0030] Working principle of the utility model: when the device is used to feed materials to the feeding end of the injection molding machine, the first motor 7 is started to work, driving the double groove wheel 8 to rotate. Since the double groove wheel 8 is driven by the transmission belt 11 and the first transmission wheel 9 and the second transmission wheel 10, the stirring mechanism and the feeding mechanism can be driven to work synchronously. Only one motor is needed to realize the stirring and feeding operations, saving energy consumption and equipment investment costs, thereby reducing the injection molding production cost. When the first transmission wheel 9 rotates, the rotating rod 13 is driven to rotate. Since the active bevel gear 14 is meshed with the driven bevel gear 16, the stirring shaft 15 is driven to rotate, and the stirring rod 17 can be driven to rotate to stir the plastic particles in the storage tank 1 to prevent accumulation and facilitate unloading and transportation. When the second transmission wheel 10 rotates, the auger blade 20 on the rotating shaft 19 is driven to rotate, and the plastic particles falling into the feeding barrel 4 can be forcibly transported, and the feeding is stable.

[0031] When a blockage occurs in the blanking pipe 3, the second motor 22 is started to drive the cam 23 to rotate. When the cam 23 abuts against the slider 25, the slider 25 is pushed upward. At this time, the compression spring 26 is squeezed and contracted to generate elastic force, and at the same time, the dredging rod 27 is driven to move upward. When the cam 23 continues to rotate and separates from the slider 25, the elastic force of the compression spring 26 is used to push the dredging rod 27 fixed to the slider 25 to move downward and reset, thereby realizing the reciprocating up and down displacement movement of the dredging rod 27, thereby dredging the plastic particles in the blanking pipe 3, playing a role in preventing blockage, and the anti-blocking effect is good.
