Description

Technical Field

[0001] This application relates to the technical field of injection molding machines, and particularly to a plastic processing injection molding machine. Background Art

[0002] A plastic injection molding machine is also called a plastic injection molding machine or a plastic injection machine. It is the main molding equipment for making various shaped plastic products using thermoplastic or thermosetting plastics with plastic molding dies. It is divided into vertical, horizontal, and all-electric types. A plastic injection molding machine can heat plastic, apply high pressure to the molten plastic, and inject it to fill the mold cavity. Existing plastic injection molding machines usually use a hopper to convey plastic particles into it. However, since the hopper is generally set as an inverted cone, the diameter of its discharge port is relatively small, and plastic particles are likely to accumulate at the discharge port, causing blockage. For this reason, a plastic processing injection molding machine is proposed. Summary of the Utility Model

[0003] In order to solve the problem that the hopper of the existing injection molding machine is generally set as an inverted cone, the diameter of its discharge port is relatively small, and plastic particles are likely to accumulate at the discharge port, causing blockage, this application provides a plastic processing injection molding machine.

[0005] A plastic processing injection molding machine includes an injection molding machine body. An inlet hopper is provided at the feed inlet of the injection molding machine body. The discharge pipe of the inlet hopper includes an outer rigid pipe and an inner flexible pipe. The upper ports of the outer rigid pipe and the inner flexible pipe are both fixedly connected to the inlet hopper. The lower port of the outer rigid pipe is fixedly and penetratively installed at the feed inlet of the injection molding machine body. A flaring mechanism is provided at the bottom of the inner flexible pipe.

[0006] Preferably, the flaring mechanism includes multiple groups of sliders fixedly installed on the outer surface of the inner flexible pipe. Sliding grooves adapted to the sliders are provided on the surface of the outer rigid pipe. One end of the slider penetrates through the sliding groove to the outside of the outer rigid pipe, and a moving mechanism is provided at the end of the slider located outside the outer rigid pipe. The moving mechanism can drive the slider to move inside the sliding groove.

[0007] Preferably, at least three groups of sliders are provided, and the sliders are distributed in a circular array with the axis of the inner flexible pipe as the base point.

[0008] Preferably, the moving mechanism includes a toothed plate fixedly installed at one end of the slider. The toothed plates are all located outside the outer rigid tube. A toothed ring is rotatably connected to the surface of the injection molding machine body. The toothed ring is sleeved on the outer surface of the outer rigid tube. A plurality of double-headed gears are rotatably connected to the surface of the injection molding machine body. The double-headed gears correspond to the toothed plates one by one. One end of the double-headed gear meshes with the toothed ring, and the other end of the double-headed gear meshes with the toothed plate. A fixing plate is also fixedly installed on the upper surface of the injection molding machine body. A motor is fixedly installed on the surface of the fixing plate. The output shaft of the motor is fixedly connected to one of the double-headed gears.

[0009] Preferably, the outer rigid tube, the inner flexible tube, and the toothed ring are all coaxially arranged, and the slider is arranged in the radial direction of the outer rigid tube.

[0010] In summary, the present application includes the following beneficial technical effects:

[0011] The discharge channel of the feed hopper in the present utility model is arranged in a double-layer structure. Among them, the outer rigid tube located on the outer layer is used to support the feed hopper, and the inner flexible tube located on the inner layer is used to convey the plastic particles in the feed hopper. And by setting the flaring mechanism to cooperate with the inner flexible tube, when the plastic particles are blocked inside the inner flexible tube, the flaring mechanism can be used to increase the diameter of the inner flexible tube, so that the plastic particles blocked inside the inner flexible tube can be smoothly discharged, ensuring the normal feeding function of the feed hopper.

[0016] The following further describes the present application in detail with reference to the attached Figures 1-3 drawings.

[0017] The embodiment of the present application discloses a plastic processing injection molding machine, including an injection molding machine body 1. A feed hopper 2 is arranged at the feed inlet of the injection molding machine body 1. The discharge pipeline of the feed hopper 2 includes an outer rigid tube 3 and an inner flexible tube 4. The upper ports of the outer rigid tube 3 and the inner flexible tube 4 are both fixedly connected to the feed hopper 2. The lower port of the outer rigid tube 3 is fixedly and penetratingly installed at the feed inlet of the injection molding machine body 1. A flaring mechanism is arranged at the bottom of the inner flexible tube 4.

[0018] In this embodiment, the discharge channel of the feed hopper 2 is arranged in a double-layer structure. Among them, the outer hard pipe 3 located on the outer layer is used to support the feed hopper 2, and the inner flexible pipe 4 located on the inner layer is used to convey the plastic particles in the feed hopper 2. And it is used in cooperation with the inner flexible pipe 4 by setting a flaring mechanism. When the plastic particles are blocked inside the inner flexible pipe 4, the flaring mechanism can be used to increase the diameter of the inner flexible pipe 4, so that the plastic particles blocked inside the inner flexible pipe 4 can be smoothly discharged, ensuring the normal material conveying function of the feed hopper 2.

[0019] Furthermore, the flaring mechanism includes multiple groups of sliders 8 fixedly installed on the outer surface of the inner flexible pipe 4. Sliding grooves 11 adapted to the sliders 8 are formed on the surface of the outer hard pipe 3. One end of the slider 8 penetrates through the sliding groove 11 to the outside of the outer hard pipe 3, and moving mechanisms are arranged at the ends of the sliders 8 located outside the outer hard pipe 3. The moving mechanisms can drive the sliders 8 to move inside the sliding grooves 11.

[0020] Furthermore, at least three groups of sliders 8 are provided, and the sliders 8 are distributed in a circular array with the axis of the inner flexible pipe 4 as the base point.

[0021] Furthermore, the moving mechanism includes a toothed plate 5 fixedly installed at one end of the slider 8. The toothed plates 5 are all located outside the outer hard pipe 3. A toothed ring 7 is rotatably connected to the surface of the injection molding machine body 1. The toothed ring 7 is sleeved on the outer surface of the outer hard pipe 3. And multiple groups of double-headed gears 6 are rotatably connected to the surface of the injection molding machine body 1. The double-headed gears 6 correspond to the toothed plates 5 one by one. One end of the double-headed gear 6 is meshed with the toothed ring 7, and the other end of the double-headed gear 6 is meshed with the toothed plate 5. A fixed plate 9 is also fixedly installed on the upper surface of the injection molding machine body 1. A motor 10 is fixedly installed on the surface of the fixed plate 9. The output shaft of the motor 10 is fixedly connected to one of the double-headed gears 6.

[0022] Furthermore, the outer hard pipe 3, the inner flexible pipe 4 and the toothed ring 7 are all coaxially arranged, and the sliders 8 are arranged in the radial direction of the outer hard pipe 3.

[0023] In this embodiment, the motor 10 is used to drive one of the double-headed gears 6 to rotate. Since the double-headed gear 6 is meshed with the toothed ring 7, the toothed ring 7 and the other double-headed gears 6 are driven to rotate synchronously. And because the double-headed gear 6 is meshed with the toothed plate 5, the toothed plate 5 and the slider 8 also move accordingly. The movement of the slider 8 can thus pull the inner flexible pipe 4 to move, expanding or resetting the diameter of the inner flexible pipe 4. The movement direction of the slider 8 is controlled by the rotation direction of the motor 10.

[0024] It should be noted that: the switch interface of the motor 10 is connected to an external power supply through a wire. The circuits involved and the driving program for the rotation direction of the motor 10 are all conventional existing technologies and will not be elaborated here.
