DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of this patent to clearly and completely describe the technical solutions in the embodiments of this patent. Obviously, the described embodiments are only part of the embodiments of this patent, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0021] See also Figure 1-2This patent provides a technical solution: a crushing and recycling device for metal cutting waste, including a shell 1, a rotating shaft 2 is rotatably installed on the inner wall of the shell 1, the rotating shaft 2 is connected to an external motor, a crushing wheel 3 is sleeved on the outside of the rotating shaft 2, and a cutting mechanism 4 is installed inside the shell 1, and the cutting mechanism 4 is arranged above the rotating shaft 2;

[0022] The cutting mechanism 4 can cut off the long thin strips of cutting waste and shorten their length, thereby preventing the waste from winding around the crushing wheel 3 and affecting the crushing of the cutting waste by the crushing wheel 3;

[0023] The cutting mechanism 4 includes an electric control push rod 41, a support plate 42, a cutter 43 and a top block 44. The outer wall of the housing 1 is provided with the electric control push rod 41, which is electrically connected to an external power supply. The output end of the electric control push rod 41 is provided with a support plate 42, and a cutter 43 is provided on the side wall of the support plate 42. The cutter 43 penetrates through the side wall of the housing 1. The side wall of the housing 1 is provided with a top block 44, which can fit with the cutter 43.

[0024] When the waste enters the housing 1, the electric control push rod 41 is started, driving the support plate 42 to slide left and right, so that the waste inside the housing 1 is cut off through the cooperation of the top block 44 and the cutter 43;

[0025] A grinding mechanism 5 is slidably mounted on the side wall of the top block 44, and the grinding mechanism 5 can fit with the end of the cutter 43;

[0026] Because the blade of the cutter 43 is inevitably damaged after multiple cuttings, resulting in a decrease in sharpness, the device is provided with a grinding mechanism 5 on its top block 44, so that the cutter 43 can be ground without removing the cutter 43, which is very convenient to operate.

[0027] Specifically, the grinding mechanism 5 includes a sliding block 51, a slot 52 and a tungsten steel blade 53. The side wall of the top block 44 is provided with a slot 6, the sliding block 51 is slidably installed in the slot 6, the side wall of the sliding block 51 is provided with a slot 52, the cutter 43 can be inserted into the slot 52, and a tungsten steel blade 53 is installed on the inner wall of the slot 52. There are two tungsten steel blades 53, and the two tungsten steel blades 53 are arranged at a V-shaped angle.

[0028] Herein, the cutter 43 is in the shape of a flat strip. When grinding, the cutter 43 needs to be inserted into the slot 52 first, and then the sliding block 51 in the sliding slot 6 is slid so that the sliding block 51 slides from one side of the top block 44 to the other side. While sliding, the tungsten steel blade 53 in the slot 52 will grind the cutter 43 to improve the sharpness of the cutter 43.

[0029] Specifically, a feed hopper 7 is sleeved on the upper part of the housing 1, and placement grooves 8 are provided on both the left and right sides of the inside of the feed hopper 7, and a conveyor belt 9 is installed in the placement groove 8, and the conveyor belt 9 is electrically connected to an external power supply;

[0030] The conveyor belt 9 can drive the cutting waste to move downward and enter the shell 1. Since the conveyor belt 9 continuously drives the cutting waste in the feed hopper 7 downward, the cutting waste on the upper layer will squeeze the cutting waste on the lower layer, thereby preventing the cutting waste from stopping moving in the shell 1 and affecting the cutting efficiency.

[0031] Specifically, a discharge port 10 is provided at the bottom of the shell 1, and support frames 11 are installed at the four corners of the lower end of the shell 1;

[0032] The support frame 11 props up the housing 1 so that sufficient space is left below the discharge port 10 for placing a material receiving trolley.

[0033] Specifically, a stopper 12 is installed on the inner wall of the feed hopper 7, and there are two stoppers 12, which are respectively located above the two conveyor belts 9;

[0034] By setting the stopper 12, it is possible to prevent the cut waste from entering between the conveyor belt 9 and the placement groove 8, which would increase the difficulty for the staff to clean the device.

[0035] Specifically, a horizontal plate 13 is installed on the side wall of the support frame 11, a threaded hole 14 is opened on the upper wall of the horizontal plate 13, a screw rod 15 is rotatably installed in the threaded hole 14, and a universal wheel 16 is installed below the screw rod 15;

[0036] When the device is working, the device is supported by the support frame 11. If the position of the device needs to be moved, the screw 15 can be rotated to support the device through the universal wheel 16, so as to facilitate the movement of the position of the device.

[0037] Working principle: When cutting, first start the external motor to drive the rotating shaft 2 to rotate, so that the crushing wheel 3 rotates with the rotating shaft 2. In this article, the rotation directions of the two rotating shafts 2 are opposite, the left one rotates clockwise, and the right one rotates counterclockwise. Then put the cut waste into the feed hopper 7, and under the drive of the internal conveyor belt 9, the cut waste enters the shell 1, and then the electric control push rod 41 is started to drive the support plate 42 to slide left and right, so that it can cut the waste inside the shell 1 through the cooperation of the top block 44 and the cutter 43;

[0038] The cut cutting waste will fall between the two crushing wheels 3 for further crushing. When the cutting force of the cutter 43 decreases, the cutter 43 needs to be inserted into the slot 52 first, and then the sliding block 51 in the sliding slot 6 is slid so that the sliding block 51 slides from one side of the top block 44 to the other side. While sliding, the tungsten steel blade 53 in the slot 52 will grind the cutter 43 to improve the sharpness of the cutter 43.

[0039] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
