Description

Technical Field

[0001] This utility model relates to the field of screw conveyor technology, specifically to a screw conveyor with a feeding structure. Background Technology

[0002] Because injection molding machines are large and have high inlet heights, a screw feeder is needed to transport plastic raw materials into the machine's hopper during the injection molding process. Since most plastic raw materials are packaged in bags, operators need to lift the bags, cut them open, and then pour the plastic raw materials into the screw feeder. When operators lift the bags, they may lose their grip, causing the plastic raw materials to spill. Furthermore, lifting the bags for extended periods of time makes feeding plastic raw materials more tiring and laborious for the operators.

[0003] In summary, there is a current need for a screw conveyor with a feeding structure. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a screw conveyor with a feeding structure, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A screw conveyor with a feeding structure includes a frame, an inlet hopper fixedly disposed on the inner side of the frame, a screw conveyor pipe connected to the outlet of the inlet hopper, one end of the screw conveyor pipe passing through a first through slot, the first through slot being opened on the right side of the frame, an opening slot being opened on the inner bottom of the frame near the rear, and second through slots being opened on both the left and right sides of the frame near the rear.

[0007] Furthermore, a lead screw is rotatably connected to the inner wall of the second through-slot, and the upper end of the lead screw passes through the second through-slot and is connected to the output shaft of the first motor.

[0008] Furthermore, a movable frame is provided through the lead screw, and a support plate frame is fixedly connected to the inner end of the movable frame. A first rotating shaft is rotatably connected to the inner wall of the support plate frame, and a limiting plate frame is fixedly connected to the inner end of the first rotating shaft.

[0009] Furthermore, the inner side of the limiting plate frame is provided with a sliding groove, and the two limiting plate frames are slidably connected to the material box through the two sliding grooves. The lower end of the material box is provided with a roller.

[0010] Furthermore, the first rotating shaft on one side passes through the support plate frame and is connected to the second rotating shaft via a meshing gear set, and the second rotating shaft is connected to the output shaft of the second motor.

[0011] This utility model provides a screw conveyor with a feeding structure. Compared with the prior art, it has the following advantages:

[0012] First, the plastic raw material from the packaging bag is poured into the material box. The material box is moved and adjusted by the rollers and slidably connected between the limiting plate frame through the slide groove. The limiting plate frame on both sides limits and fixes the material box. Under the action of the first motor and the lead screw, the moving frame moves and adjusts on the lead screw, thereby lifting the material box containing the plastic raw material, reducing manual operation. At the same time, the material box loads the plastic raw material, avoiding the plastic raw material from spilling during the lifting process of the original packaging bag. After being lifted to an appropriate height, the second motor, the second rotating shaft, the meshing gear set and the first rotating shaft drive the limiting plate frame to rotate, thereby causing the material box to flip and pour the plastic raw material in the material box into the hopper, and then convey it through the spiral conveyor pipe.

[0024] The opening slot 5 facilitates the movement of the material box 14 between the limiting plate frame 12.

[0025] In this embodiment, a lead screw 7 is rotatably connected to the inner wall of the second through slot 6. The upper end of the lead screw 7 passes through the second through slot 6 and is connected to the output shaft of the first motor 8. A movable frame 9 is installed through the lead screw 7.

The inner end of the first rotating shaft 11 is fixedly connected to a limiting plate frame 12.

[0026] By the action of the first motor 8 and the lead screw 7, the moving frame 9 moves and adjusts on the lead screw 7, thereby lifting the material box 14 containing plastic raw materials.

[0027] Example 2

[0028] like Figures 1-5 As shown, based on the above embodiments, this embodiment further provides the following:

[0029] In this embodiment, a sliding groove 13 is provided on the inner side of the limiting plate frame 12. The two limiting plate frames 12 are slidably connected to the material box 14 through the two sliding grooves 13. A roller 15 is provided at the lower end of the material box 14. A first rotating shaft 11 on one side passes through the support plate frame 10 and is connected to the second rotating shaft 17 through the meshing gear set 16.

[0030] The second motor 18, the second rotating shaft 17, the meshing gear set 16 and the first rotating shaft 11 drive the limiting plate frame 12 to rotate, thereby causing the material box 14 to flip and pour the plastic raw material in the material box 14 into the hopper 2.

[0031] Working principle and usage process of this utility model:

[0032] In use:

[0033] Step 1: Pour the plastic raw material from the packaging bag into the material box 14, move and adjust the material box 14 under the action of the roller 15, and slide the material box 14 between the limiting plate frame 12 through the slide groove 13. The limiting plate frame 12 on both sides limits and fixes the material box 14.

[0034] Step 2: Under the action of the first motor 8 and the lead screw 7, the moving frame 9 moves and adjusts on the lead screw 7, thereby lifting the material box 14 containing plastic raw materials, reducing manual operation. At the same time, the plastic raw materials are loaded through the material box 14. After being lifted to an appropriate height, the limiting plate frame 12 is driven to rotate by the second motor 18, the second rotating shaft 17, the meshing gear set 16 and the first rotating shaft 11, thereby causing the material box 14 to flip and pour the plastic raw materials in the material box 14 into the hopper 2, and then conveyed through the spiral conveying pipe 3.
