DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] Reference Figure 1-6 An injection molding production line includes an injection molding machine 1 and a conveyor belt 2. A frame 3 is fixedly arranged at the lower end of the injection molding machine 1. One end of the conveyor belt 2 is arranged in the frame 3. A fixed frame 11 is arranged on the injection molding machine 1. An injection molding head 13 is connected to the fixed frame 11 through a cylinder mechanism 12. The conveyor belt 2 is arranged below the discharge end of the injection molding machine 1.

[0030] A collecting hopper 4 is provided on the frame 3, and the collecting hopper 4 is provided between the injection molding machine 1 and the conveyor belt 2, the feeding port of the collecting hopper 4 corresponds to the discharging end of the injection molding machine 1, and the discharging port of the collecting hopper 4 corresponds to the conveyor belt 2;

[0031] The collecting hopper 4 is provided with an anti-blocking mechanism 5 , the frame 3 is fixedly provided with a mounting frame 6 , and the mounting frame 6 is provided with a motor 7 for driving the anti-blocking mechanism 5 .

[0032] In the present invention, the workpieces molded by the injection molding machine 1 are transferred to the conveyor belt 2 through the collecting hopper 4, and the anti-blocking mechanism 5 is provided to prevent the workpieces molded by the injection molding machine 1 from being blocked in the collecting hopper 4, so that the workpiece unloading is smoother. In this embodiment, the cylinder mechanism 12 includes a cylinder fixedly provided on a fixed frame 11, and the output shaft of the cylinder is fixedly provided with a connecting frame. The injection head is provided on the connecting frame, and the combined mold composed of the movable mold and the fixed mold is injection molded. After the workpiece is injection molded, the injection molding head is controlled by the cylinder to move downward to eject the workpiece to avoid adhesion.

[0033] Furthermore, in this embodiment, the anti-blocking mechanism 5 includes a material guiding portion 51 slidably disposed in the collecting hopper 4, and the material guiding portion 51 is power-connected to the motor 7 via a connecting rod mechanism. The motor 7 controls the material guiding portion 51 to move up and down via the connecting rod mechanism, thereby clearing the collecting hopper 4.

[0034] In this embodiment, the connecting rod mechanism includes an eccentric wheel 52 fixedly arranged on the output shaft of the motor 7, and a connecting rod 53 is rotatably connected to the eccentric wheel 52, and the connecting rod 53 is rotatably connected to the material guide part 51. When the motor 7 drives the eccentric wheel 52 to rotate, the eccentric wheel 52 will pull or drag the connecting rod 53 to move, thereby driving the material guide part 51 to move up and down, thereby clearing the collecting hopper 4.

[0035] Furthermore, in the present embodiment, a slide groove 54 cooperating with the material guiding portion 51 is provided on one side of the collecting hopper 4, and the connecting rod mechanism includes a connecting portion 55 fixedly arranged on one side of the material guiding portion 51 and cooperating with the slide groove 54, and the connecting portion 55 is rotatably connected with the connecting rod 53. When the connecting rod 53 moves, it will drive the connecting portion 55 and the material guiding portion 51 to move up and down, and because it is a rotatably connected structure, when the angle of the connecting rod 53 changes, it will not affect the linear movement of the connecting portion 55 and the material guiding portion 51.

[0036] In this embodiment, a guide groove 56 is provided on the material guide part 51, and a guide block 57 matching with the guide groove 56 is fixedly provided on the inner wall of the collecting hopper 4. The guide block 57 cooperates with the guide groove 56 on the material guide part 51 to limit the moving trajectory of the material guide part 51, so that it moves up and down in a straight line.

[0037] It should be noted that, in the present embodiment, a first return spring 58 is provided between the guide block 57 and the guide groove 56, and an exhaust hole is provided on the guide block 57 or the material guide portion 51. The material guide portion 51 is moved upward and reset by the first return spring 58, so that the material guide portion 51 can move back and forth to clear the collecting hopper 4. The exhaust hole is provided to prevent the air inside the guide groove 56 from affecting the operation of the material guide portion 51.

[0038] In this embodiment, the anti-blocking mechanism 5 also includes a knocking assembly 8 arranged on one side of the aggregate hopper 4. The knocking assembly 8 is power-connected to the eccentric wheel 52. The aggregate hopper 4 is knocked by the knocking assembly 8, so that the aggregate hopper 4 and the workpieces inside it vibrate, thereby loosening the workpieces and moving them downward to avoid blockage.

[0039] In addition, in this embodiment, the knocking assembly 8 includes a bracket 81 fixedly connected to the collecting hopper 4, and a knocking part 82 is slidably provided on the bracket 81. The knocking part 82 is connected to a guide part 83 that cooperates with the eccentric wheel 52. The knocking part 82 is driven by the guide part 83 to move and knock on the outer wall of the collecting hopper 4.

[0040] In this embodiment, a second reset spring is connected between the knocking part 82 and the bracket 81, and the guide part 83 includes a connecting plate 831, on which a guide rod 832 is fixedly connected. The second reset spring is elastically deformed and accumulates potential, so that the knocking part 82 is controlled to knock on the aggregate hopper 4 when resetting.

[0041] To say it in more detail, in the present embodiment, a groove 84 cooperating with the guide rod 832 is provided on the eccentric wheel 52. When the eccentric wheel 52 rotates, the guide part 83 drives the knocking part 82 to move, and the second return spring undergoes elastic deformation and accumulates potential. When the guide part 83 is in the groove 84, it loses support from the support object, and the second return spring undergoes deformation and resets, driving the knocking part 82 to contact the collecting hopper 4 to knock it. The eccentric wheel 52 is also provided with a guide groove 85 cooperating with the guide rod 832. The guide rod 832 is movably connected to the guide groove 85. The guide groove 85 is provided to guide the guide rod 832 to prevent it from being separated from the eccentric wheel 52.

[0042] Working mode: When working, the injection molding of the workpiece is carried out through the injection molding machine 1, and the eccentric wheel 52 is driven to rotate by the motor 7, pulling or dragging the connecting rod 53 to move, thereby driving the material guide part 51 to move up and down, and the collecting hopper 4 is unblocked. The material guide part 51 is moved up and reset by the first return spring 58, so that the material guide part 51 can move back and forth to unblock the collecting hopper 4. When the eccentric wheel 52 rotates, the guide part 83 drives the knocking part 82 to move, and the second return spring undergoes elastic deformation and accumulates potential. When the guide part 83 is in the groove 84, it loses support from the support object, and the second return spring undergoes deformation and reset, driving the knocking part 82 to contact the collecting hopper 4 and knock it, so that the workpieces are loosened and moved downward to avoid blockage.
