Description

Technical Field

[0001] The utility model relates to the technical field of profile production, in particular to a blanking device for a profile forming machine. Background Art

[0002] Each raw material used in profile production forms building materials through an extrusion method according to a specific process ratio, and is widely used in window frames, stair handrails, wire troughs, skirting boards, special-shaped pipes, etc., and has the advantages of light weight, corrosion resistance, and easy transportation.

[0003] In the initial processing stage of profiles, the material ratios used for each batch of profiles are different. When a batch of profiles completes the production volume, the mold is replaced, the residual raw materials inside are cleaned, and new materials are replenished for the production of the next batch of profiles. Therefore, during the discharging process, it is necessary to clean the hopper on the extruder and empty the raw materials. In the original design, the hopper and the extruder are directly connected by a flange spiral, resulting in difficult discharging. For this reason, we propose a blanking device for a profile forming machine to solve the above problems. Content of the Utility Model

The bottom of the hopper is detachably connected with a connecting hopper. One side of the bottom of the connecting hopper is provided with a discharging pipe, and a cover is detachably connected to the discharging pipe. A conveying pipe is arranged at the bottom of the connecting hopper, and the conveying pipe is communicated with the connecting hopper. One end of the conveying pipe is connected with a connecting material box, and an observation window is detachably installed on the top of the connecting material box.

[0024] In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the accompanying drawings.

[0025] See Figures 1-3 , a blanking device for a profile forming machine. This application mainly focuses on the feeding work in the profile extrusion stage. While solving the problem of discharging materials, it also further improves the stability of feeding and discharging. Specifically, it includes a hopper 1 for storing raw materials. The hopper 1 is a conical hopper in the original design. The bottom of the hopper 1 is detachably connected to a connecting hopper 2. The connecting hopper 2 and the hopper 1 are connected by a flange. A clamp 3 is provided on the flange between the hopper 1 and the connecting hopper 2. When disassembling, simply loosen the clamp 3 to separate the hopper 1 and the connecting hopper 2. Lift the hopper 1 by a crane to complete the cleaning work of the connecting hopper 2. Since the hopper 1 can be directly made of aluminum alloy or plastic, due to its small size and light weight, it can be directly removed during disassembly and reinstalled after cleaning. Further, a docking pipe 13 is also provided at the bottom of the hopper 1. The docking pipe 13 extends into the connecting hopper 2, which can be used for positioning when installing the hopper 1 and can also improve the sealing performance when the clamp 3 is fixed;

[0026] The bottom of the connecting hopper 2 is hemispherical, which is not easy to form dead corners and is convenient for discharging materials. A discharge pipe 6 is installed on one side of the bottom of the connecting hopper 2. The discharge pipe 6 is located at a position offset by 20° - 30° from the vertical line directly below the connecting hopper 2, so as to discharge the raw materials as much as possible during discharging. A cover 5 is detachably connected to the discharge pipe 6, and the cover 5 is threadedly connected to the discharge pipe 6, which is convenient for the disassembly of the cover 5. During specific discharging, the discharge pipe 6 is opened, and the bag for loading is put on the discharge pipe 6 to complete the discharging. A conveying pipe is arranged at the bottom of the connecting hopper 2. The conveying pipe is directly below the connecting hopper 2 and is connected to the connecting hopper 2. During the working process, the materials in the connecting hopper 2 enter the conveying pipe and are stably conveyed by the conveying pipe. Specifically, the conveying pipe can adopt the form of an air chute or a screw auger. One end of the conveying pipe is connected to a connecting material box 9, and the materials sent by the conveying pipe are sent into the connecting material box 9. The connecting material box 9 is connected to the extruder through a flange, and the materials are sent to the extruder through the connecting material box 9. On the one hand, an observation window 10 can be detachably installed on the top of the connecting material box 9. The observation window 10 is made of transparent material, so that the feeding situation can be observed without disassembly, improving the reliability of the equipment. On the other hand, it is convenient for the materials to be further mixed in the connecting material box 9, improving the consistency of the materials.

[0027] In the present utility model, in order to discharge the raw materials completely without opening the hopper 1, a nozzle 11 is provided on the side wall of the connecting hopper 2. During installation, the nozzle 11 is arranged obliquely downward, as Figure 2 and Figure 3 shown, compressed air can be blown out along the tangential direction of the side wall of the connecting hopper 2 to clean the connecting hopper 2 and complete the discharging. Further, a compressed air pipe 4 is connected to the side of the nozzle 11 located outside, and compressed air enters through the external compressed air pipe 4. During installation, the relevant compressed air pipes 4 are all controlled by air valves and can be started during cleaning. It should be noted that the method of cleaning with compressed air will generate dust. Therefore, it is best to put a dust-proof bag in the discharge pipe 6 to collect the raw materials.

[0028] In the present utility model, the conveying pipe includes a feeding pipe 7 equipped with a screw auger 12. In this application, the materials are conveyed by the screw auger 12, which can ensure the stable and continuous conveying of the materials. A driving structure connected to the screw auger 12 is installed at one end of the feeding pipe 7, and the other end of the feeding pipe 7 is connected to the connecting material box 9. When the screw auger 12 is conveying, it reduces the generation of dust, is convenient for observing the feeding situation, and can also stir and mix the raw materials.

[0029] As can be seen from the above technical solutions, when feeding materials in this application, the materials are still sent to the hopper 1, enter the conveying pipe through the connecting hopper 2, and then enter the extruder through the connecting material box 9. When changing the materials, open the discharge pipe 6 to discharge the materials in the connecting hopper 2. Further, when the materials in the connecting hopper 2 cannot be completely discharged, the hopper 1 can be removed by a crane (manually), and the materials in the connecting hopper 2 can be discharged through the discharge pipe 6 with a brush, and then reinstalled. This application can completely discharge the materials in the feeding equipment when changing the materials, with simple operation and convenient discharging. Moreover, during the normal working stage, it can discharge materials stably and observe the feeding situation of the raw materials, improving the observability and stability during the feeding stage.
