Description

Technical Field

[0001] This application relates to the technical field of chip removal for milling machines, and particularly to a chip removal mechanism for milling machines. Background Art

[0002] With the rapid development of science and technology and industrial production, the precision, efficiency, and requirements of machining are constantly increasing. Milling machines are often used for large workpieces. With the rapid development of milling machines, the requirements for chip removal mechanisms of milling machines have also increased. The chip removal mechanism of a milling machine is a device specifically designed to collect the chips generated during milling machine processing.

[0003] Compared with the actual use process, among the existing chip removal mechanisms for milling machines, one is to drive and convey the collected chips through a worm. However, since the milled metal chips are all in a curly sheet shape and relatively fluffy, this causes the chips to occupy too much internal space of the collection mechanism during the collection process, resulting in frequent replacement of the chip collection mechanism and thus reducing the processing efficiency.

[0004] Therefore, to solve the above problems, this application provides a chip removal mechanism for milling machines.

[0005] The above information disclosed in this background art is only used to increase the understanding of the background art of this application. Therefore, it may include prior art that is not known to those of ordinary skill in the art. Utility Model Content

[0008] Three support rods are welded inside the feed hopper. In the middle of the tops of the three support rods, a bearing is rotatably connected. A rotating rod is rotatably connected to the middle of the bearing. A grinding bowl is welded to the bottom of the rotating rod. A number of grinding teeth are welded to the outer edge of the grinding bowl and the inner surface of the grinding bin.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following is a further detailed description of the present application in conjunction with the attached Figures 1 - 3 to further illustrate the present application.

[0021] Embodiment 1

[0022] Referring to Figures 1 - 3 , a chip removal mechanism for a milling machine includes a support chamber 1. A fixing frame 2 is welded to the top inside of the support chamber 1. The middle of the top end of the fixing frame 2 is welded with a bottom chamber 3. The top end of the bottom chamber 3 is welded with a grinding chamber 4. The diameter of the grinding chamber 4 is smaller than the width of the support chamber 1. In order to prevent the ground debris from flowing out of the outside of the collection mechanism, the bottom end inside the grinding chamber 4 is funnel-shaped. In order to enable the unground debris to slide towards the feed end of the grinding mechanism, a plurality of discharge windows 5 are opened at the connection between the grinding chamber 4 and the top end of the bottom chamber 3. A crushing motor 6 is installed in the middle inside the bottom chamber 3 through a base. The top end of the grinding chamber 4 is welded with a feed hopper 7;

[0023] Inside the feed hopper 7, three support rods 8 are welded. In the middle of the tops of the three support rods 8, a bearing 9 is rotatably connected. In order to support the grinding mechanism and make it more stable, a rotating rod 10 is rotatably connected in the middle of the bearing 9. At the bottom end of the rotating rod 10, a grinding bowl 11 is welded. The top end of the bottom bin 3 is frustum-shaped. The driving end of the crushing motor 6 penetrates through the top end of the bottom bin 3 and is connected to the bottom end of the grinding bowl 11. A number of grinding teeth 12 are welded on the outer edge of the grinding bowl 11 and the inner surface of the grinding chamber 4. In order to grind the debris, both the top and bottom ends of the grinding bowl 11 are arc-shaped. The grinding teeth 12 welded on the outside of the grinding bowl 11 and the inside of the grinding chamber 4 are meshed with each other. The debris collection cart 13 is slidably inserted into the inner bottom end of the support bin 1.

[0024] Working principle: First, the operator places the feed hopper 7 of the equipment at the debris discharging end of the milling machine. Then, the crushing motor 6 is started. At this time, the crushing motor 6 will drive the grinding bowl 11 connected to its driving end to rotate with the bottom bin 3 as the support. And the grinding bowl 11 will drive the rotating rod 10 welded to its top end to rotate. The top end of the rotating rod 10 is rotatably connected to the inside of the bearing 9, and the bearing 9 is supported and connected by three support rods 8. This can ensure the stability of the grinding bowl 11 during rotation. As more and more grinding debris falls into the inside of the feed hopper 7 through the milling machine, the debris will enter the gap between the grinding chamber 4 welded to the bottom end of the feed hopper 7 and the grinding bowl 11.

[0025] With the rotation of the grinding bowl 11, the grinding teeth 12 welded on the outside of the grinding bowl 11 and the grinding teeth 12 welded on the inside of the grinding chamber 4 will crush the debris during rotation. This can break the fluffy milling debris. The crushed debris will slide down through the arc-shaped top of the bottom bin 3 until it slides out through the discharge window 5 opened at the connection between the grinding chamber 4 and the bottom bin 3, and then slides into the inside of the debris collection cart 13 slidably inserted at one end of the support bin 1. As the rotation continues, more and more debris will accumulate. And since the width of the support bin 1 is greater than the diameter of the bottom bin 3, during the period when the debris slides out, the debris will not slide out of the outer side of the top end of the support bin 1. This can enable the storage mechanism to store more debris compared to the previous one of the same volume. After the debris collection cart 13 stores a certain amount of debris inside, the operator can pull out the debris collection cart 13 and replace it with a new one. The universal wheels at the bottom end of the debris collection cart 13 can increase the replacement speed and improve the overall processing efficiency.

[0026] The above are all the preferred embodiments of this application. The protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
