Description

Technical Field

[0001] The utility model relates to the technical field of diamond production equipment, in particular to a diamond micro-powder crushing device. Background Art

[0002] Diamond is commonly known as "diamond drill", which is the original body of diamond we often say. It is a mineral composed of carbon. Diamond powder has high hardness and good wear resistance. It can be widely used in cutting, grinding, drilling, etc. It is an ideal raw material for grinding and polishing high-hardness materials such as cemented carbide, ceramics, gemstones, optical glass, etc. In the industrial production process, diamond is widely used in the cutting and processing of handicrafts and industrial products.

[0003] Graphite can form artificial diamonds under high temperature and high pressure. In the production process of diamond micropowder, most of them need to be shaped and crushed by the diamond matrix. In the existing crushing device, when the diamond matrix is ​​loaded, it is often concentrated or even accumulated in the middle position of the crushing roller, which not only affects the crushing efficiency, but also easily causes blockage. The middle position of the crushing roller will also wear more seriously than the two sides, affecting the crushing effect. Utility Model Content

[0004] The utility model aims to provide a diamond micro powder crushing device, which can improve the crushing efficiency and is not prone to clogging problems.

[0005] In order to achieve the above-mentioned purpose, the utility model discloses a diamond micro powder crushing device, which comprises:

[0006] case;

[0007] A crushing roller is disposed inside the shell and is rotatably connected to the side wall of the shell;

[0008] A driving member, driving the crushing roller to rotate;

[0009] A feeding mechanism is arranged on the top of the shell, and the feeding mechanism includes a linear moving module, a hopper and a control component. The linear moving module drives the hopper to move, and the moving direction of the hopper is parallel to the length direction of the crushing roller. The hopper has a discharge port, and the control component controls the opening and closing of the first discharge port, and the first discharge port extends into the interior of the shell and is arranged close to the crushing roller.

[0010] A screen is placed inside the shell and below the crushing roller, and the screen is tilted;

[0011] A return box is movably arranged at the bottom of the slope of the screen, and a first channel opening for the return box to enter and exit is provided on the shell, and the return box can cover the first channel opening.

[0012] Through the above arrangement, the crushing process of the diamond matrix is ​​carried out inside the shell, which can prevent the fragments from splashing and avoid the loss of precious raw materials. By setting a linear moving module to drive the hopper to move, the diamond matrix can be evenly loaded along the length direction of the crushing roller during loading. The crushing operation will not be concentrated in the middle position of the crushing roller. The utilization rate of the crushing roller is higher and it is less likely to be blocked. The middle position of the crushing roller is less likely to suffer from mechanical fatigue and cause severe wear, which extends the service life of the crushing roller. The discharge port of the hopper is set close to the crushing roller to reduce the collision, bounce and splash of the diamond matrix. The crushed bodies that cannot be screened are collected through the return box, and the return box can be easily taken out, so that the crushed bodies that cannot be screened can be re-loaded for secondary crushing.

[0013] Preferably, the control assembly includes a control valve, a control chip and two trigger switches. The control valve is installed in the hopper, one of the trigger switches is arranged near one end of the linear moving module, and the other trigger switch is arranged near the other end of the linear moving module. The linear moving module or the hopper can touch the trigger switch; the control valve and the trigger switch are connected to the control chip. After being touched, the trigger switch continuously sends out a high level or low level signal (the switching condition of the high and low levels is that the trigger switch is touched) and feeds back to the control chip. The control valve can be set to open only when the signals sent by the two trigger switches are the same or different. After such a setting, the hopper will only discharge materials when going out or returning each time it goes back and forth. Such a setting can well improve the blockage problem.

[0014] Preferably, the hopper includes a storage tank and an extension pipe, a funnel is provided at the bottom of the storage tank, one end of the extension pipe is connected to the funnel, and the other end of the extension pipe is the discharge port; a long hole is provided on the top of the shell for the extension pipe to pass through.

By providing a swing assembly, it is possible to prevent diamond micropowder from sticking to the screen, and it is also possible to facilitate the crushed body that cannot pass the screen to roll into the return box.

[0019] Preferably, a guide port adapted to the return box is formed on the fixed frame; a mounting port is also provided above the first channel port, the mounting port is communicated with the first channel port, a baffle is provided in the mounting port, the upper end of the baffle is rotatably connected to the shell, under normal conditions, the baffle blocks the mounting port, and the baffle is pushed, and the lower end of the baffle can block the guide port. The setting of the guide port can facilitate the crushed body that cannot pass the sieve to roll into the return box. By setting the baffle, when the return box is taken out, the discharge of the guide port can be temporarily blocked to prevent the crushed body that cannot pass the sieve from mixing into the diamond powder.

[0020] Preferably, a limit pin is further included, and a first limit hole and a second limit hole adapted to the limit pin are provided in the installation opening, and the limit pin is plugged and matched with the first limit hole to limit the movement of the baffle plate to the outside of the shell, and the limit pin is plugged and matched with the second limit hole to keep the baffle plate blocking the material guide port.

[0038] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0039] like Figures 1 to 5As shown, the utility model discloses a diamond powder crushing device, which includes: a housing 10, a crushing roller 20, a driving member 30, a feeding mechanism, a screen 50, a return box 70, a swing assembly 60 and a collecting bin 80. The housing 10 has an inner cavity, the crushing roller 20 is placed in the inner cavity, and the crushing roller 20 is rotatably connected to the side wall of the housing 10, and the driving member 30 drives the crushing roller 20 to rotate. The driving member 30 selects a motor, and the driving member 30 can be installed outside the housing 10.

[0040] The feeding mechanism is arranged at the top of the housing 10, and includes a linear moving module 41, a hopper 42 and a control assembly. The linear moving module 41 is a prior art. In this case, it includes a slide rail 411, a threaded rod 412, a slider 413 and a motor 414. The slide rail 411 and the threaded rod 412 are parallel to each other. The slider 413 is slidably connected to the slide rail 411, and the threaded rod 412 is threadedly connected to the slider 413. The motor drives the threaded rod 412 to rotate. The hopper 42 is mounted on the slider 413. After such arrangement, the hopper 42 can move along the length direction of the guide rail under the drive of the motor 414, and the guide rail is parallel to the crushing roller 20. By controlling the operation of the motor 414 of the linear moving module 41, the hopper 42 can be made to move back and forth, and then the feeding can be carried out back and forth along the length direction of the crushing roller 20. The diamond matrix fed will not be accumulated in a certain place, and the utilization rate of the crushing roller 20 is higher.

[0041] The hopper 42 includes a storage tank 421 and an extension tube 423. A funnel 422 is provided at the bottom of the storage tank 421. One end of the extension tube 423 is connected to the funnel 422, and the other end of the extension tube 423 is a discharge port 424. A long hole 11 is provided at the top of the shell 10 for the extension tube 423 to pass through. One end of the extension tube 423 with the discharge port 424 extends into the inner cavity of the shell 10, so that the discharge port 424 is arranged close to the crushing roller 20. The diamond matrix coming out of the discharge port 424 can be closer to the crushing roller 20, reducing the problems of collision, bouncing and splashing, and ensuring that the loaded diamond matrix can basically be squeezed and crushed by the crushing roller 20. In order to prevent the crushed dust from flying out of the shell 10, two elastic sealing strips 12 that abut against each other are provided in the long hole 11, such as a thin rubber strip. Under normal circumstances, the two elastic sealing strips 12 block the long hole 11. The extension tube 423 is inserted between the two elastic sealing strips 12. When the hopper 42 moves, the extension tube 423 pushes the elastic sealing strips 12 to move. In order to strengthen the strength of the extension tube 423, a reinforcing rib can be connected between the storage tank 421 and the extension tube 423.

[0042] The control component controls the orderly opening and closing of the first discharge port 424. The control component includes a control valve 431, a control chip and two trigger switches 432. The control valve 431 is installed in the hopper 42 (the position of the hopper 422). One of the trigger switches 432 is set near one end of the linear moving module 41, and the other trigger switch 432 is set near the other end of the linear moving module 41. The slider 413 of the linear moving module 41 or the hopper 42 can touch the trigger switch 432. The control valve 431 and the trigger switch 432 are connected to the control chip. After being touched, the trigger switch 432 continuously sends a high level or low level signal (the switching condition of the high and low levels is that the trigger switch 432 is touched) and feeds back to the control chip. The control valve 431 can be set to open only when the signals sent by the two trigger switches 432 are the same or different. After this setting, each round trip of the hopper 42 will only discharge materials when going or returning. This setting can well improve the blockage problem.

[0043] The screen 50 is placed inside the shell 10 and below the crushing roller 20, and the screen 50 is tilted. The screen 50 includes a fixed frame 51 and a filter 52, and the edge of the filter 52 is fixedly connected to the fixed frame 51.

The screen 50 can be inserted into the shell 10 from the second channel opening 15, which is convenient for replacement, cleaning and maintenance of the screen 50. Although the screen 50 is tilted, its inclination should not be too large. However, when the inclination is small, the crushed body that cannot be screened will not roll down along the slope, so a swing assembly 60 is provided to assist.

[0044] The swing assembly 60 is arranged outside the housing 10, and includes a swing cylinder 61, a seesaw 62, a pin 63 and a connector 64. The seesaw 62 is rotatably connected to the housing 10. An oblong hole 621 is provided at one end of the seesaw 62, and a socket 622 and a pin hole are provided at the other end of the seesaw 62. The seat of the swing cylinder 61 is connected to the housing 10. A sliding member 611 matching the oblong hole 621 is provided on the push rod of the swing cylinder 61. The sliding member 611 is connected to the oblong hole 621. When the swing cylinder 61 is actuated, the seesaw 62 can be pushed to perform the seesaw 62 action. The connector 64 is plugged into the socket 622, and the pin 63 is plugged into the pin hole, and the pin 63 restricts the connector 64 from slipping out of the socket 622 (the connector 64 is also provided with a socket matching the pin 63). A groove 641 is provided on the connecting piece 64, and a handle 512 is provided on the fixing frame 51 to limit the groove 641. By setting the swing assembly 60, the screen 50 can be repeatedly pulled to prevent the diamond powder from sticking to the screen 50, and it can also help the crushed body that cannot pass the screen to roll into the return box 70. The connecting piece 64 is connected to the seesaw 62 in a plug-in manner and is limited by the pin 63, which can facilitate loading and unloading and facilitate the removal of the screen 50.

[0045] The return box 70 is used to collect the crushed bodies that cannot be screened. The return box 70 is movably arranged at the bottom of the slope of the screen 50. A guide port 513 adapted to the return box 70 is formed on the fixed frame 51. The housing 10 is provided with a first passage opening 14 for the return box 70 to enter and exit. The return box 70 is inserted into the first passage opening 14, and the return box 70 can cover the first passage opening 14. The crushed bodies collected by the return box 70 are re-introduced into the hopper 42.

[0046] A mounting opening 17 is also provided above the first channel opening 14, and the mounting opening 17 is communicated with the first channel opening 14. A baffle 171 is provided in the mounting opening 17, and the upper end of the baffle 171 is rotatably connected to the housing 10. Under normal conditions, the baffle 171 can block the mounting opening 17 to prevent diamond micropowder or crushed bodies from falling out of the housing 10. When the baffle 171 is pushed, the lower end of the baffle 171 can block the material guide opening 513, and when the return box 70 is taken out, the material guide opening 513 can be temporarily blocked from discharging materials to prevent the crushed bodies that cannot pass the sieve from mixing into the diamond micropowder.

[0047] In order to facilitate operation, a limit pin 172 is further provided, and a first limit hole 173 and a second limit hole 174 adapted to the limit pin 172 are provided in the installation opening 17. When the limit pin 172 is plugged into and matched with the first limit hole 173, the limit pin 172 abuts against the lower end position of the baffle 171 and restricts the baffle 171 from moving outside the housing 10, ensuring that the baffle 171 can reliably block the installation opening 17. When the limit pin 172 is plugged into and matched with the second limit hole 174, the limit pin 172 abuts against the upper end position of the baffle 171, so that the baffle 171 maintains a state of shielding the material guide opening 513.

[0048] In addition, a preliminary plate 18 can be provided inside the housing 10. The preliminary plate 18 is provided at an angle to limit the position where the falling object falls on the screen 50. Some fine powders and crushed bodies may temporarily stick to the crushing roller 20 after being crushed. In addition, some possible splashing diamond matrixes may also fall directly. By providing the preliminary plate 18, all the falling objects are screened by the screen 50. In addition, some fine powders may also stick to the crushed bodies. During the rolling process of the crushed bodies, this part of the fine powders can also be separated to a certain extent.

[0049] The collecting bin 80 is movably arranged inside the housing 10. A third passage opening 16 for the collecting bin 80 to enter and exit is arranged below the housing 10. The collecting bin 80 is located below the screen 50. By arranging the collecting bin 80, the collection and removal of the diamond powder can be facilitated.
