Description

Technical Field

[0001] The utility model relates to the technical field of diamond grinding wheel production equipment, in particular to a raw material grinding equipment for diamond grinding wheel production. Background Technique

[0002] The production of diamond grinding wheels requires a material mixing stage, in which diamond abrasives are evenly mixed with binders such as resins, metal powders, ceramics, etc., and possible fillers. In order to improve the effect of material mixing, it is necessary to ensure that the materials are ground sufficiently, which requires thorough pulverization of materials including metals. After retrieval, the patent with the application number CN201921931814.1 discloses a sheet metal grinding device. During the rotation of the second pulley, the rocker is driven to rotate, thereby driving the moving of the support plate. During the movement of the support plate, the sheet metal is driven to move on the upper surface of the top plate. When the sheet metal moves to the first inclined plate, it moves along the surface of the first inclined plate into the pulverizer body for preliminary pulverization, avoiding insufficient pulverization caused by the accumulation of sheet metals. The feeding is uniform, increasing the efficiency during pulverization.

[0003] The above device needs to place the sheet metal in a fixed direction in advance. Otherwise, the sheet metal is easily blocked by the hopper of the pulverizer in the direction perpendicular to the pulverizer, resulting in inability to enter the interior of the pulverizer, and it is difficult to automatically adjust the direction of the sheet metal to make the stacked and conveyed sheet metal automatically move into the hopper of the pulverizer along its length direction.

[0027] The following will describe the implementation manners of the present application in detail in conjunction with the accompanying drawings and embodiments, so as to fully understand the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects and implement accordingly.

[0028] Embodiment 1

[0029] If the sheet metal moves into the feed hopper along its width direction, it is easily blocked by the feed hopper and cannot enter the feed hopper. Therefore, it is necessary to adjust the feeding direction of the sheet metal. Refer to Figures 1-6 For an embodiment of the present utility model, a raw material grinding device for diamond grinding wheel production is proposed, which includes a crusher 1 and a conveying frame 2 used in cooperation. A feed hopper 3 is installed at the top of the crusher 1, and support legs 4 are installed at the bottom of the conveying frame 2. A belt conveyor 5 is installed inside the conveying frame 2, and a direction adjustment assembly 6 is installed at one end of the conveying frame 2 close to the feed hopper 3. A guiding frame 7 fixed to the conveying frame 2 is installed between the belt conveyor 5 and the direction adjustment assembly 6. During use, the sheet metal in the raw materials for diamond grinding wheel production is placed on the belt conveyor 5, and the belt conveyor 5 conveys the sheet metal towards the feed hopper 3. The sheet metal slides onto the direction adjustment assembly 6 through the guiding frame 7. The direction adjustment assembly 6 adjusts the sheet metal so that its length direction is consistent with its moving direction, and then moves one end of the sheet metal into the feed hopper 3. After passing through the feed hopper 3, it enters the crusher for crushing and grinding. It can automatically adjust the direction of the sheet metal, so that the stacked and conveyed sheet metal automatically moves into the hopper of the crusher along its length direction, preventing the sheet metal from being blocked by the hopper of the crusher in a direction perpendicular to the crusher and causing it to be unable to enter the crusher.

[0030] In order to achieve the purpose of automatically adjusting the direction of the sheet metal, the direction adjustment assembly 6 is provided in this embodiment. Refer to Figure 3 and Figure 4, the direction adjustment component 6 includes a long block 61 installed inside the conveying frame 2. The top of the long block 61 is an arc surface. A plurality of receiving grooves are formed in the top of the long block 61. Inside the receiving groove, a swing block 62 with the same top as the long block 61 is rotatably connected. A columnar groove is formed on one side of the top of the swing block 62 close to the guide frame 7. Inside the columnar groove, a rotating column 63 with one end extending out of the swing block 62 is provided. A rubber pad 64 is fixedly connected to the top of the rotating column 63. A bent plate 65 is fixedly connected to the side of the long block 61 away from the rubber pad 64. A spring 66 is fixedly connected between the swing block 62 and the bent plate 65. During use, the sheet metal on the belt conveyor 5 slides to the top of the swing block 62 through the guide frame 7, and then continues to slide towards the feed hopper 3 along the arc surface of the top of the swing block 62. Since most of the sheet metal is supported by the guide frame 7 on the guide frame 7 at the beginning stage, the force of the sheet metal pressing on the swing block 62 is small and cannot push the swing block 62 to rotate and compress the spring 66. When most of the sheet metal slides onto the swing block 62, the weight of the sheet metal on the swing block 62 pushes the swing block 62 to rotate and move an angle towards the feed hopper 3, compressing and contracting the spring 66. At this time, the rotating column 63 and the rubber pad 64 rotate to the highest position of the swing block 62 to support the sheet metal.

[0031] Since the sheet metal is not symmetrically distributed on the rubber pad 64, with one end always longer and the other end shorter, the longer end will deflect downward and press the rubber pad 64 to bend. After deflecting downward, the sheet metal will drive the rotating column 63 to rotate until the longer end rotates to the position closest to the feed hopper 3, making the length of the sheet metal consistent with its moving direction. The rubber pad 64 can not only increase the friction between the sheet metal and the rotating column 63 to prevent the sheet metal from slipping when being driven by the rotating column 63, but also bend downward after being pressed by the heavier end of the sheet metal, making the heavier end of the sheet metal downward, so as to drive the rotating column 63 to rotate by using the gravity distribution, making the longer end of the sheet metal move to the position close to the feed hopper 3. Moreover, due to the different positions of the sheet metal distributed on the rotating column 63, the lengths of the sheet metal at the left and right ends of the rotating column 63 are different. Therefore, the angles of inclination of the sheet metal after pressing the rubber pad 64 are also different, which makes the adjacent sheet metals not affect each other when rotating after tilting at different angles. Finally, the longer end of the sheet metal on the rotating column 63 gradually slides towards the feed hopper 3 under the action of its own gravity. After passing through the feed hopper 3, it enters the crusher 1 and is crushed and ground. After the sheet metal falls off the rotating column 63, the spring 66 pushes the swing block 62 to rotate to the initial position, repeating the above process, continuously adjusting the direction of the sheet metal, and being able to automatically adjust the direction of the sheet metal after most of the sheet metal moves onto the swing block 62. At the same time, when adjusting the direction, the sheet metal is tilted at different angles to prevent adjacent sheet metals from affecting each other when adjusting the direction.

[0032] In order to improve the efficiency of crushing and grinding sheet metal, a cutting assembly 9 is provided in this embodiment to cut the relatively large sheet metal into small pieces. Refer to Figure 5 and Figure 6 , the guiding frame 7 includes a support rod 71 fixedly connected to the conveying frame 2. The top of the support rod 71 is fixedly connected with an inclined plate 72. The feed hopper 3 extends below the inclined plate 72. An inclined plate 8 is fixedly connected to the middle inside the feed hopper 3. A plurality of screening holes penetrating the conveying frame 2 are formed in the top of the inclined plate 72. A cutting assembly 9 is installed at the bottom of the inclined plate 8. The cutting assembly 9 includes side plates 91 fixedly connected to the bottom of the inclined plate 8. A cutting wheel 92 is rotatably connected to one side of the side plates 91. The cross section of the cutting wheel 92 is a semi-circle. A long groove adapted to the cutting wheel 92 is formed in the top of the inclined plate 8. A motor 93 for driving the cutting wheel 92 to rotate is installed on one side of the side plates 91.

[0033] During use, the relatively small sheet metal directly falls into the feed hopper 3 through the screening holes on the inclined plate 72, and then directly passes through the feed hopper 3 from one side of the inclined plate 8 and enters the crusher 1 for crushing and grinding. For the relatively large sheet metal, after the direction is adjusted by the direction adjustment assembly 6, it falls onto the inclined plate 8 inside the feed hopper 3, and then slides down along the inclined plate 8 past the cutting wheel 92. The cutting wheel 92 rotates one circle to cut the sheet metal passing above it once, cutting the sheet metal into small pieces. Then the cut sheet metal slides down along the inclined plate 8 and finally enters the crusher 1 through the feed hopper 3 for crushing and grinding. It can screen the sheet metal, directly crush and grind the relatively small sheet metal, shorten the conveying distance of the relatively small sheet metal, reduce the possibility of the relatively small sheet metal falling into the gap during conveying, and perform cutting treatment on the relatively large sheet metal to reduce the volume of the sheet metal, thereby reducing the difficulty of crushing and grinding the sheet metal.

[0034] Embodiment Two

[0035] In order to further set the direction of the sheet metal during conveying, refer to Figures 1-7 , on the basis of Embodiment One, a brush assembly 11 is proposed. An outer frame 10 is fixedly connected to the top of the conveying frame 2. The brush assembly 11 is installed on the outer frame 10. The brush assembly 11 includes a cross plate 111 installed on the outer frame 10. A brush head 112 is fixedly connected to the bottom of the cross plate 111. The cross plate 111 is slidably connected to the top of the outer frame 10. A notch adapted to the brush head 112 is formed in the top of the outer frame 10. The brush head 112 extends into the conveying frame 2 movably. A plurality of bolts 12 movably penetrating the outer frame 10 are provided on the top of the cross plate 111.

[0036] During use, the sheet metal being conveyed on the belt conveyor 5 rubs against the brush head 112, squeezing and bending the brush head 112. The brush head 112 is arranged parallel to the conveying direction of the belt conveyor 5, so that the length direction of the sheet metal is blocked by the brush head 112 during the movement process and gradually tends to the movement direction. It can gradually adjust the direction of the sheet metal during the conveying process, making the length direction of the sheet metal gradually tend to its movement direction, facilitating the entry of the sheet metal into the inside of the feed hopper 3 and being cut. At the same time, it can also clean the dust attached to the surface of the sheet metal.
